Acute renal failure is typical in patients with renal cortical necrosis, with associated complications (eg, hyperkalemia, fluid overload). Chronic renal failure, occurring in 30-50% of patients, requires dialysis and transplantation.
The average hospital stay is 1 to 3 nights which varies depending on type of surgery and your overall condition. Duodenal switch surgery: 2 to 3 days; Gastric bypass surgery: 2 to 3 days; Gastric sleeve surgery: 2 to 3 days; Mini gastric bypass: 2 to 3 days; Gastric banding surgery (LAP-BANDÂ®): 1 day or less; Gastric Balloon: Same-day (outpatient)
Mini-gastric bypass is a quicker operation compared to traditional laparoscopic gastric bypass surgery. Operating times are reduced, on average by 50 minutes (Laparoscopic Roux-en-Y Versus Mini-Gastric Bypass for the Treatment of Morbid Obesity). The stomach is divided with a laparoscopic stapler.
