Segmentectomy is the excision (removal) of a portion of any organ or gland. The procedure has several variations and many names, including segmental resection, wide excision, lumpectomy, tumorectomy, quadrantectomy, and partial mastectomy.
[edit on Wikidata] Jejunostomy is the surgical creation of an opening (fistula) through the skin at the front of the abdomen and the wall of the jejunum (part of the small intestine). It can be performed either endoscopically, or with formal surgery. A jejunostomy may be formed following bowel resection in cases where there is a need for bypassing the distal small bowel and/or colon due to a bowel leak or perforation.
