*<IP_ADDRESS> Content of HSE plan*

The content of HSE plan includes, but not limited to, the following contents; in other words, the main contents of the HSE plan are as follows:

	- "Project overview, worksite, and the surroundings" and "personnel and equipment" are set up to identify hazardous factors. For projects of mobile operations, changes may most likely happen to the project itself and the surrounding environment, personnel, equipment, and facilities, so the HSE plan focuses on these two parts for comprehensive identification of hazardous factors. Specifically, in the "personnel and equipment" part, potential risks are identified through analyzing changes (placement, shifts, etc.) in project personnel (especially those in key positions), and appropriate measures are developed. Regarding equipment and facilities, risks arising from frequent relocation and installation are considered, such as safety accessories lost, damaged, etc.
	- "Identification of additional hazardous factors and main risk warnings" and "risk prevention, mitigation, and control" are the focus of the HSE plan. When compiling the plan, the first step is to identify hazardous factors through analyzing the "project overview, worksite, and the surroundings" and "personnel and equipment." On this basis, the next step is to refer to the HSE guidance to determine additional hazardous factors of the project (i.e., hazardous factors of the project that are not included in the HSE guidance), then find out the to-be-controlled hazardous factors and main risks of the project through risk assessment, and develop risk control measures against additional hazards. As to the control of main risks, given that the main risks are mostly discipline-related conventional risks whose control measures have been included in the position-specific HSE guidance, there is no need to develop risk control measures against additional hazards in the HSE plan. But if the main risks of the project are unconventional risks, control measures must be included in the HSE plan.

○ "Emergency response plan" is not the main content of the HSE plan but an annex to the plan for educational purpose. According to the current situation of emergency management work, at present every grassroots organization will develop a variety of emergency response plans based on the characteristics of the discipline, so there is no need to repeat the preparation of emergency response plan when compiling the HSE plan. But if the emergency response plan is not operable, you need to modify and improve it. In addition, it should be noted that the "emergency response plan" in the HSE plan and the "emergency response procedures" in the HSE guidance are different but related. The "emergency response procedures" is a part of the "emergency response plan." Being included in the position-specific HSE guidance, the "emergency response procedures" is provided for educational purpose. The "emergency response plan" is set up considering significant risks of a project, which is provided for communication before the start of a project. Once there are significant risks spreading out of control, the "emergency response plan" shall be launched immediately and call for the professional rescue force to minimize the consequences of the accident.

In order to further simplify the preparation of HSE plan for small projects or activities and to enhance the dynamic risk management of long-cycle projects, we added the risk management sheet (**Table 2**) to the version II template of the HSE plan. When using the HSE-TDOC, grassroots organizations may conduct risk management referring to the risk management sheet in the following cases:

Case one: for operating projects with long cycle and relatively fixed location (e.g., drilling of exploratory wells and critical wells and refinery shutdown for maintenance), compile the project-specific HSE plan, and incorporate the risk management sheet into the HSE plan before construction. During the construction process, carry out identification of hazardous factors on a regular basis, identify additional hazards which may arise as time changes, develop appropriate risk mitigation and control measures based on the HSE plan, and fill in the risk management sheet as a supplement to the HSE plan.

Case two: for operations with long cycle and mobile location (e.g., geophysical exploration operation and pipeline construction), compile the project-specific HSE plan, and incorporate the risk management sheet into the HSE plan before construction. During the construction process, timely identify additional hazards which may arise as time and environment change; develop appropriate risk mitigation and control measures based on the HSE plan, and fill in the risk management sheet as a supplement to the HSE plan.

Case three: for operational activities with short cycle and mobile location that are carried out in the same block (e.g., drilling of development shallow wells, downhole repair and fracturing, mud logging, wireline logging, and cementing operations that are carried out in the same block), compile the block-specific HSE plan, and incorporate the risk management sheet into the HSE plan before construction. Before single-well construction in the same block, identify additional hazards which may arise as time and environment change; and develop appropriate mitigation and control measures based on the HSE plan, and fill in the risk management sheet as a supplement to the HSE plan.

Case four: for operational activities with short cycle and relatively fixed location (e.g., production auxiliary operations, refinery temporary inspection, and maintenance), carry out hazard identification activities and fill in the risk management sheet before operation.

## *4.2.3 The HSE checklist*

#### *<IP_ADDRESS> Content of HSE checklist*

Compilation of the HSE checklist should be based on the principle of territorial management. The territorial scope of different positions should be divided, and the territorial management categories of tools, machines, equipment, and facilities should be defined. The key components, critical parts, and vulnerable parts should be highlighted according to the relevant inspection standards.

Compared with HSE guide and HSE plan, HSE checklist is quite simple. Just like the HSE guide, HSE checklist is prepared according to different work posts. The

worker should be responsible for the condition of hardware (machinery, equipment, tools) he/she uses or manages; the items need to be checked will be listed in his/her HSE checklist in order to facilitate his/her inspection; special attention should be given to the critical parts or vulnerable components of facilities. It is a form designed according to a scientifically reasonable route (order) to prompt inspection personnel to do his/her check efficiently.

#### *<IP_ADDRESS> Compilation and application of HSE checklist*

For worksites of different natures, the ways to compile the HSE checklist are different. For example, the checklist for the standardized and customized worksites of drilling and other operations can be compiled together with the HSE guidance due to the relative fixed placement of equipment and facilities and remains relatively fixed. Different checklists should be developed according to the placement of field equipment and facilities for construction and other worksites where the placement of equipment and facilities is not fixed.

The HSE checklist is a form designed to cover all the abovementioned inspection contents according to a scientifically reasonable route (order). During shift changes or patrol inspections, relevant personnel may pay more attention to the equipment, facilities, tools, and machines under their control and be referring to the checklist, especially the critical parts of the equipment and facilities, so as to improve the efficiency of discovering hazards and ensure that the hardware facilities are in a safe condition. Although the HSE checklist is relatively simple compared with "two documents," it focuses on the inspection on the safety state of objects, which is not included in the HSE case.

### **5. HSE-TDOC works as project risk management mode**

In the HSE-TDOC risk management mode, the HSE guidance can be used to control conventional operational risks; the HSE plan can be used to prevent unconventional operational risks, i.e., the "two documents" are to regulate human behavior; and the HSE checklist, i.e., "one checklist," can be used to inspect the state of objects. HSE-TDOC not only can be used for the risk control of mobile projects but also for the safety management of fixed workplaces. Besides, HSE-TDOC not only can be used for safety management in normal conditions but also for emergency response. Therefore, HSE-TDOC could serve as a HSE risk management mode to manage HSE risks arising from daily production and operation activities in grassroots organizations. Till now, HSE-TDOC as project risk management mode has been successfully applied in the frontline organizations of China National Petroleum Corporation (CNPC) for more than 20 years [11].

#### **5.1 HSE guidance for conventional operational risk management**

Conventional risks are the risks arising from conventional operational activities. As the content and environment of conventional operational activities are relatively fixed, the pre-established operating procedures and technical specifications such as standard operating procedures (SOP) are usually adopted for this kind of risk management. To give play to the role of risk prevention of such operating procedures and technical specifications, education for employees is required. Only through education, behavior of employees can be regulated. In order to have employees to grasp the position-specific operating procedures, the pre-established operating

procedures and technical specifications are put into the HSE guidance. Through educating with the HSE guidance in daily training, the knowledge including the operating procedures can be grasped by employees, and the operating procedures can only be obeyed by them on the basis of their knowing, otherwise if they know

At present, although many enterprises have paid great attention to staff education/training, the training effect is not satisficing due to single method, disorganized contents, and lack of continuity [12–16]. To a certain extent, the HSE guidance has solved problems relating to staff technical skill training. As the HSE guidance contains all the information that should be grasped by employees such as position-specific operating procedures and emergency response procedures, it is a collection of technical skills that should be grasped by employees for a specific position. Through continuous education of the HSE guidance, employees will grasp all the knowledge required by the position and hence improve their skills to

The HSE plan is a document developed to prevent unconventional risks of a project that are not included in the HSE guidance. Unconventional risks not only include risks arising from a variety of unconventional activities which cannot be normalized by the pre-established operating procedures and technical specifications due to the changes such as the content or environment of the operational activities but also risks arising from various changes. It should be clear that if the risk has been already managed by either PTW (the risks arising from excavation, hot work, work at height, temporary electricity, entry into confined space, etc.) or MOC or other management tools, there is no need to mention in the HSE plan. The HSE plan is designed to manage the risks that have not been controlled by either HSE guidance or PWT or MOC or other management tools that have not been man-

Due to the reason that the management of unconventional risks of a project is not included in the HSE guidance which is about the management of conventional risks, they can be basically managed by means of the combined use of HSE plan, PTW, and MOC. Therefore, all the identified risks (conventional risks + unconventional risks) can be managed through the combined use of HSE guidance and

thereby improving the efficiency of safety check.

Based on the principle of territorial management, HSE checklist is a form designed according to a scientifically reasonable route (order) to prompt inspection personnel to pay more attention to critical parts or vulnerable components of field hardware facilities that are used or managed by employees on each position, such as tools and machines, equipment, etc., in order to improve the efficiency of discovering hidden dangers.

The HSE plan is a document developed to prevent unconventional risks of a project that are not included in the HSE guidance.

Due to the reason that the management of unconventional risks of a project is not included in the HSE guidance which is about the management of conventional risks, they can be basically managed by means of the combined use of HSE plan, PTW, and MOC.

Pancreatic surgery has higher morbidity and mortality than other forms of gastrointestinal tract surgery, due to associated problems like pancreatic fistula formation and loss of pancreatic function. Until recently laparoscopic surgery of the pancreas was limited to laparoscopic staging or to the evaluation of periampullary cancer for detecting small metastatic nodules or local invasion (Jang et al., 2007; Schachter et al., 2000). Advances in laparoscopic techniques and instrumentation have expanded the role of laparoscopic surgery to a degree that could not have been imagined such as Whipple's procedure (Gagner & Gentileschi, 2001).

Recent reports on laparoscopic surgery of the pancreas are encouraging and support the advantages of laparoscopy. We believe that well selected enucleation and laparoscopic distal pancreatectomy, with or without spleen preservation, are acceptable and recommendable for the treatment of benign or low grade malignant diseases of the pancreas. Moreover, surgeons and laparoscopic industries have developed new techniques and devices that increase convenience, ease, and safety of complicated laparoscopic surgeries, and these efforts will undoubtedly increase the role of laparoscopic or minimal invasive surgery for the treatment of pancreatic disease.

In this chapter, we will discuss the current status of the laparoscopic pancreatic surgery and the role of its associated procedures for the treatment of pancreatic disease.

Most of reports demonstrate the feasibility of laparoscopic approach with acceptable morbidity (10~30%) and nearly no mortality.

Laparoscopic Pancreatic Surgery 31

According to several reports comparing the clinical results of laparoscopic surgery with open surgery, no statistical differences were found in terms of operation time, morbidity, or recurrence. However, mean length of hospital stay was shorter in the laparoscopic group than in the open surgery group (Table 2) ( Vijan et al., 2010; Kooby et al., 2008; Velanovich, 2006; Misawa et al., 2007; Teh et al., 2007; Kim et al., 2008; Matsumoto et al., 2008; Eom et al.,

We could conclude that laparoscopic distal pancreatectomy is a safe and feasible method equivalent to open distal pancreatectomy in terms of early and late outcome for benign and borderline lesions of pancreas such as pancreas cystic neoplasms and neuroendocrine tumors. Considering superior cosmetic results and early functional recovery, laparoscopic distal pancreatectomy could be treatment of choice in most of non-cancerous diseases

The role of laparoscopic distal pancreatectomy for the treatment of pancreatic cancer remains controversial. Many pancreatic surgeons worry about the oncological safety of laparoscopic pancreatectomy in relation to surgical margin, retroperitoneal clearance, and

Several reports showed that laparoscopic distal pancreatectomy provided similar short- and long-term oncologic outcomes as compared with open surgery, with potentially shorter hospital stay even in pancreatic cancer. These results suggest that laparoscopic distal pancreatectomy is an acceptable approach for resection of pancreatic ductal adenocarcinoma (PDAC) of the left pancreas in selected patients (Kooby & Chu, 2010; Dulucq et al., 2005;

Although the result of laparoscopic distal pancreatectomy for pancreatic cancer seems to be favorable in limited cases, we must wait for more long term results to reach a conclusion on

Spleen preservation and method of preservation are important issues of laparoscopic distal pancreatectomy, and surgeons showed diverse preferences for surgical method (Table 1). Spleen-preserving distal pancreatectomy was introduced by Mallet et al. in 1943 (Mallet & Vachon, 1943), and as knowledge of the immunologic role of spleen increased, efforts to

According to the recently published data, 15~70% of distal pancreatectomies were performed preserving spleen (Table 1). Two techniques are employed during spleenpreserving operations. The first involves splenic artery and vein transection such that the left gastroepiploic vessels and short left gastric vessels will supply the spleen (Warshaw's technique) (Warshaw, 1997), whereas in the second the splenic artery and vein are preserved

This second method demands more advanced instrumentation and skill in terms of dividing the transverse branches of splenic vessels and has a risk of left-sided portal hypertension if

Table 2. Comparisons of laparoscopic and Open distal pancreatectomy

According to several reports comparing the clinical results of laparoscopic surgery with open surgery, no statistical differences were found in terms of operation time, morbidity, or recurrence. However, mean length of hospital stay was shorter in the laparoscopic group than in the open surgery group (Table 2) ( Vijan et al., 2010; Kooby et al., 2008; Velanovich, 2006; Misawa et al., 2007; Teh et al., 2007; Kim et al., 2008; Matsumoto et al., 2008; Eom et al., 2008; Nakamura et al., 2009).

We could conclude that laparoscopic distal pancreatectomy is a safe and feasible method equivalent to open distal pancreatectomy in terms of early and late outcome for benign and borderline lesions of pancreas such as pancreas cystic neoplasms and neuroendocrine tumors. Considering superior cosmetic results and early functional recovery, laparoscopic distal pancreatectomy could be treatment of choice in most of non-cancerous diseases located at pancreas body and tail.

The role of laparoscopic distal pancreatectomy for the treatment of pancreatic cancer remains controversial. Many pancreatic surgeons worry about the oncological safety of laparoscopic pancreatectomy in relation to surgical margin, retroperitoneal clearance, and retrieval of peripancreatic lymph node (Kubota, 2011; Kooby & Chu, 2010).

Several reports showed that laparoscopic distal pancreatectomy provided similar short- and long-term oncologic outcomes as compared with open surgery, with potentially shorter hospital stay even in pancreatic cancer. These results suggest that laparoscopic distal pancreatectomy is an acceptable approach for resection of pancreatic ductal adenocarcinoma (PDAC) of the left pancreas in selected patients (Kooby & Chu, 2010; Dulucq et al., 2005; Kooby et al., 2010).

Although the result of laparoscopic distal pancreatectomy for pancreatic cancer seems to be favorable in limited cases, we must wait for more long term results to reach a conclusion on oncological safety of laparoscopic resection for pancreatic cancer.

Spleen preservation and method of preservation are important issues of laparoscopic distal pancreatectomy, and surgeons showed diverse preferences for surgical method (Table 1). Spleen-preserving distal pancreatectomy was introduced by Mallet et al. in 1943 (Mallet & Vachon, 1943), and as knowledge of the immunologic role of spleen increased, efforts to conserve the organ have intensified (Robey et al., 1982; Yamaguchi et al., 2001).

According to the recently published data, 15~70% of distal pancreatectomies were performed preserving spleen (Table 1). Two techniques are employed during spleenpreserving operations. The first involves splenic artery and vein transection such that the left gastroepiploic vessels and short left gastric vessels will supply the spleen (Warshaw's technique) (Warshaw, 1997), whereas in the second the splenic artery and vein are preserved (Figure 1).

This second method demands more advanced instrumentation and skill in terms of dividing the transverse branches of splenic vessels and has a risk of left-sided portal hypertension if the splenic vein becomes occluded after surgery (Yoon et al., 2009).

Whereas Warshaw's technique is technically easy and requires shorter operative time (Kaneko et al., 2004; Mori et al., 2005), it may result in splenic infarction and splenic abscess formation due to insufficient blood flow to the spleen (Warshaw, 1997).

#### **2.2 Pancreatoduodenectomy**

Although laparoscopic pancreatoduodenectomy was introduced at 1994 by Dr. Gagner (Gagner & Pomp, 1994), this procedure is still technically challenging.

There have been limited case reports on laparoscopic pancreatoduodenectomy (Table 3) (Gagner & Pomp, 1997; Staudacher et al., 2005; Dulucq et al., 2006; Palanivelu et al., 2007; Pugliese et al., 2008; Cho et al., 2009; Kendrick & Cusati, 2010), and some surgeons advocate its safety and feasibility. However, lack of tactile sensation, difficulties in localizing lesions, and the anatomic complexity of peripancreatic organs to make laparoscopic pancreatoduodenectomy difficult (Cuschieri, 1996).

Even Dr. Gagner, the initiator of laparoscopic pancreatoduodenectomy, concluded that this procedure offers no advantage in terms of patient outcome and may be associated with increased morbidity (Gagner & Pomp, 1997). Nevertheless, laparoscopic experience has allowed some surgeons to claim promising results for laparoscopic pancreatoduodenectomy (Gagner & Pomp, 1997; Staudacher et al., 2005; Dulucq et al., 2006; Palanivelu et al., 2007; Pugliese et al., 2008; Cho et al., 2009; Kendrick & Cusati, 2010; Cuschieri, 1996).

However, laparoscopic pancreatoduodenectomy has many pitfalls. Pancreatoduodenectomy itself requires meticulous anastomosis to reduce morbidities associated with pancreatic leakage, and adequate dissection to remove diseased tissue including lymph nodes and nerve plexus. Small operative windows cannot highlight the merit of minimally invasive surgery in pancreatoduodenectomy because of the long operation time and high morbidity due to pancreato-enteric anastomosis.

On the other hand, it can be expected that technical advances, like robotic surgery (Makary, 2011; Horiguchi et al., 2011), will continue to make pancreatoduodenectomy by minimal invasive surgery more feasible and safe.

Laparoscopic Pancreatic Surgery 35

The yield of laparoscopy for the detection of metastatic disease, especially of small peritoneal lesions that have not been detected by imaging modalities, ranges from 15 to 46% (Jimenez et al., 2000; Menack et al., 2001; Minnard et al., 1998; Velasco et al., 1998; Liu & Traverso, 2005). Recent studies have shown lower yields for laparoscopy than for improved non invasive imaging modalities like multi detector CT. The yield of laparoscopy alone is clearly impaired by its inability to detect locally advanced or intra-parenchymal liver disease. To overcome this obvious limitation, laparoscopic ultrasound has been added to laparoscopic staging, and this leads to a marked increase in yield and accuracy (Dulucq et al., 2006). Studies comparing laparoscopy and laparoscopic ultrasound with radiological staging modalities have produced controversial results. However, several studies have found that laparoscopy and laparoscopic ultrasound are more accurate than contrast-

In contrast, three large studies using contrast-enhanced multi-detector CT imaging as a baseline radiological investigation were unable to confirm this, and found yields as low as 10-15% and accuracies of 35-56% for laparoscopy (Nieveen van Dijkum et al., 2003; Brooks et al., 2002). Despite the use of a pre-operative staging algorithm including laparoscopic ultrasound, up to 20% of patients were still found to be unresectable at the time of laparotomy, mainly because of local invasion (Talamini et al., 1998). Moreover, as diagnostic yields have fallen, due to improvements in non-invasive imaging, the additional costs of laparoscopy have been called into question, particularly since it requires separate anesthesia. Thus, at present, laparoscopy has a limited role in the staging of peri-pancreatic

The role of surgery in the management of acute pancreatitis is markedly being reduced because less invasive intervention and intensive medical care are evolving. Although some clinicians advocate a non surgical approach even in cases of infected necrotizing pancreatitis, due to the improved results of medical or interventional treatment (Chang et al., 2006), current indications for surgery in pancreatitis are infected necrotizing pancreatitis,

The treatment of infected necrosis has changed dramatically during the last few years, and a multimodality approach has emerged, where a combination of several techniques are used in a single patient, and the risks of intervention are weighed against the need for adequate

Minimally invasive surgery has consistently been shown to be associated with reduced inflammatory response activation than equivalent open surgery, and some evidence suggests that local sepsis and inflammatory response may also be lessened by minimally invasive surgery. It has been suggested that by minimizing the massive inflammatory injury associated with open pancreatic necrosectomy, a minimally invasive approach to the management of infected pancreatic necrosis may lessen the risk of multiple organ failure, and reduce respiratory and wound morbidity in necrotizing pancreatitis (Garden, 2005; Parekh, 2006).

The laparoscopic approach depends on the localization of pancreatic necrosis. The alternatives are an intraperitoneal approach, direct entry of the retroperitoneal space, and an intraperitoneal transgastric approach. Our group experienced three successful cases of

an organizing pseudocyst, or related complications.

#### **2.3 Other miscellaneous pancreatectomy and palliative procedures**

Enucleation is one of commonly conducted procedures of laparoscopic pancreatectomy. According to a review by Tagaya et al (Tagaya et al., 2003), laparoscopic enucleation has been used to treat relatively small benign or low grade malignancies, and tumors located on the surface of the pancreas remote from the pancreatic duct. Tumor location is an important factor for successful laparoscopic enucleation to avoid pancreatic duct injury, and some advocate that enucleation is a safe and simple procedure under laparoscopic ultrasonographic guidance (Matsumoto et al., 1999).

The enucleation offers the possibility of complete tumor removal without loss of pancreatic parenchyma, possible diabetes, and splenectomy in some endocrine tumor or pancreatic cystic neoplasm. However, enucleation seems to be a debatable procedure in patients with pancreas cystic tumors, and does not address the malignant potential of these tumors, and thus, should be used cautiously in selected cases to avoid inadequate safe surgical margins and rupture (Fernandez-Cruz et al., 2005). In addition, the incidence of pancreatic fistula after tumor enucleation has been reported to be 30% to 75%, which is relatively higher than that of conventional pancreatectomy (Pyke et al., 1992; Talamini et al., 1998; Iihara et al., 2001). Moreover, considerations of oncological and operational safety require that surgeons exercise caution when selecting indications for laparoscopic enucleation.

Some surgeons have developed more intricate procedures like laparoscopic central pancreatectomy and ventral pancreatectomy (Orsenigo et al., 2006; Kang et al., 2011; Giulianotti et al., 2010).

Laparoscopy may be used in a palliative context for locally advanced or metastatic pancreatic/periampullary cancers. Many patients with periampullary cancer have symptoms associated with biliary or gastric outlet obstruction, and traditionally these patients have been managed by open bypass surgery. Recently, minimally invasive laparoscopic approaches to gastric and biliary bypass have been successfully applied, and have been shown by non-randomized comparative studies to be safer and to be associated with reduced periods of hospitalization than open surgery (Schwarz & Beger, 2000; Bergamaschi et al., 1998; Rothlin et al., 1999; Rhodes et al., 1995).

Although endoscopic or radiologic procedures for palliative treatment have been enormously developed and have achieved early success rates for endoscopic stent which is comparable to those of surgery with reduced morbidity and hospital stays, the long-term results of endoscopic procedures are not as satisfactory (van den Bosch et al., 1994). Thus, randomized comparisons of laparoscopic biliary bypass and interventional biliary stents in unresectable periampullary cancer are needed.

#### **3. Laparoscopic diagnosis/staging**

Laparoscopic diagnosis and staging are controversial in patients with suspected pancreatic cancer. Its main role is to detect occult intra-abdominal metastatic disease, during the procedure any suspicious lesion can be biopsied and peritoneal cytology can also be obtained by instilling normal saline into the peritoneum (Michl et al., 2006; Merchant et al., 1999; Nieveen van Dijkum et al., 1999).

The management of pancreatic pseudocyst, complicated (acute or chronic) pancreatitis represents another important role of laparoscopy in pancreatitis. Pseudocysts complicate 5- 10% of acute pancreatitis attacks and often arise as a result of disruption of the pancreatic duct in the presence of gland necrosis. Large (≥6cm diameter), persistent (≥6 weeks), and symptomatic pseudocysts are indications for drainage, which is best achieved

Endoscopic transmural (transgastric or transduodenal) drainage may be possible in some patients with pancreatic pseudocysts, and is best reserved for pseudocysts that complicate chronic pancreatitis (rather than acute pancreatitis) in the head or body of the pancreas, and those with a wall thickness of less than 1cm (Beckingham et al., 1999). Surgery remains the gold standard for the management of large, persistent and recurrent pseudocysts. Internal drainage is conventionally achieved through a pseudocyst-gastrostomy or pseudocystjejunostomy, procedures that are now safely and effectively accomplished laparoscopically (Weber et al., 2009). Transgastric (via anterior gastrostomy) (Smadja et al., 1999), endogastric (Mori et al., 2000; Ammori et al., 2002), a posterior approach through the lesser sac, and Roux-en-Y pseudocyst-jejunostomy have been described (Hagopian et al., 2000). Although reported cases of laparoscopic management of pseudocysts are limited, the data presented are promising, and support the advantages of a relatively short postoperative hospital stay and rapid recovery (Smadja et al., 1999; Mori et al., 2000; Ammori et al., 2002; Hagopian et

#### **5. Conclusion**

The anatomical complexity of the pancreas and high postoperative morbidity have hindered evaluations of laparoscopic surgery with respect to early functional recovery, and thus, have probably retarded the adoption of laparoscopic surgery for the management of pancreatic diseases. Nevertheless, recent reports on pancreatic laparoscopic surgery are encouraging and maintain consensus option concerning the merits of the technique.

Well selected cases of enucleation and laparoscopic distal pancreatectomy with or without spleen preservation are currently both acceptable and recommendable for the treatment of benign or low grade malignant diseases of pancreas. Most reports on advanced laparoscopic pancreatectomy have concluded that these procedures are feasible and safe when conducted by skilled laparoscopic surgeons. However, technical feasibility does not obviate sound clinical judgment, and caution should be exercised before new technologies are adopted in the absence of well designed clinical trials (Werner et al., 2005).

Nevertheless many surgeons and the laparoscopic industries have developed new techniques and devices that are more convenient and increase the safety of laparoscopic surgery, and their efforts will undoubtedly increase the role of laparoscopic or minimal invasive surgery for the treatment of pancreatic disease.

**Laparoscopy in Trauma Patients**

The burden of major trauma, predominantly blunt in nature, continues to rise in most countries. More often the young are affected with lifelong debilitating consequences. Minimally invasive techniques, such as laparoscopic procedures, have become standard for the treatment of many surgical conditions, being able to minimize the impact of surgery, to reduce postoperative pain, time in hospital, time to recover, and to improve cosmetic

The use of laparoscopy as an aid in the diagnosis of abdominal trauma was first described in 1977 (Simon, Gazzaniga, Carnevale). In 1988 Cuschieri compared diagnostic peritoneal lavage with a laparoscopy (using a 4-mm scope) in blunt abdominal trauma patients demonstrating that laparoscopy carried a higher positive predictive value when compared to diagnostic peritoneal lavage (Cuschieri). Since then, the use of laparoscopy in abdominal trauma has increased exponentially. In trauma patients laparoscopy may avoid unnecessary (non-therapeutic) laparotomy, may improve operative visualisation of diaphragm, and may

Despite these clear potentialities, laparoscopy has not yet gained wide acceptation and it is

1. In bleeding, or potentially bleeding patients, timing is of essence. The logistics for laparoscopy set up of theatre still takes longer than for open surgery. Once the operation has started it takes longer to gain access, identify the bleeder and, especially,
