Billroth II, more formally Billroth's operation II, is an operation in which a partial gastrectomy (removal of the stomach) is performed and the cut end of the stomach is closed. The greater curvature of the stomach (not involved with the previous closure of the stomach) is then connected to the first part of the jejunum in end-to-side anastomosis.
All patients lose weight after gastrectomy, although the extent of weight loss is dependent on the extent of surgery (total gastrectomy vs partial gastrectomy) and the pre-operative BMI. Maximum weight loss occurs by 12 months and many patients regain weight afterwards. [6]
The Hofmeister–Finsterer operation is a partial gastrectomy, devised by Franz von Hofmeister, based upon a procedure by Eugen Pólya. It was later refined by Hans Finsterer and became known as the Hofmeister–Finsterer gastrectomy. Here upper part of the cut end of the stomach is closed and remaining lower portion is anastomosed with jejunum.
Roux-en-Y reconstruction following partial or complete gastrectomy for stomach cancer. [4] Roux-en-Y hepatico jejuno stomy used to treat (macroscopic) bile duct obstruction which may arise due to: a common bile duct tumour or hepatic duct tumour (e.g. resection of cholangiocarcinoma) [5] a bile duct injury (e.g. cholecystectomy, iatrogenic, trauma)
Sleeve gastrectomy or vertical sleeve gastrectomy, is a surgical weight-loss procedure, typically performed laparoscopically, in which approximately 75 - 85% of the stomach is removed, [1] [2] along the greater curvature, [3] which leaves a cylindrical, or "sleeve"-shaped stomach the size of a banana.
Antrectomy, also called distal gastrectomy, is a type of gastric resection surgery that involves the removal of the stomach antrum to treat gastric diseases causing the damage, bleeding, or blockage of the stomach. [1] [2] This is performed using either the Billroth I (BI) or Billroth II (BII) reconstruction method.
This procedure is similar to the sleeve gastrectomy surgery, but a sleeve is created by suturing, rather than physically removing stomach tissue. [69] This allows for the natural ability of the stomach to absorb nutrients to remain intact. [69] This procedure is reversible, is a less invasive procedure, and does not use hardware or staples. [70]
Surgery on the digestive system's organs is referred to as digestive system surgery, gastrointestinal surgery, or gastrointestinal (GI) surgery. Nutrients from the food we eat are processed and absorbed by the digestive system. Surgery could be required to remedy or treat certain problems or diseases that affect the digestive tract.
