A. The bypass biliary-pancreatic or operation Scopinaro (Diagram No. 6):
Described by an Italian surgeon, Nicola Scopinaro in 1979, is the intervention malabsorbtive type. The fact that the vast majority of the small intestine is deprived of bile and pancreatic secretions (rich in digestive enzymes) creates a poor absorption of certain foods, especially fats, resulting in an apparent weight loss without restriction in food.
In return, a serious medical surveillance is needed, and side effects or reactions are common (diarrhea). In technical terms, it includes the following times:
– Removal of half of the stomach (hemi-gastrectomy)
– Removal of the gallbladder (cholecystectomy)
– Preparation of a portion of small intestine (severed) measuring 250 cm
– Anastomosis gastrointestinal jéjunale = suture between the stomach and small intestine
– Other intestinal anastomosis, called “at the foot of the cove, about 100 cm before the cecum
(ie the junction between large and small intestine)
– The small intestine and is divided into three portions: a portion of “food”, a portion “biliary-pancreatic”
(which collects secretions liver and pancreas), and a portion.
B. The bypass biliary-digestive altered or “duodenal switch” (Diagram No. 7):
Described by Hesse and Marceau in 1995, it aims to add to bypass biliary-pancreatic conservation of the pylorus (the “sphincter” lower stomach), and a “useful” for the stomach. His times are as follows:
– Release of the stomach
– Section duodenum
– Gastrectomy
– Anse jéjunale severed climb to 250 cm of cecum
– Anastomosis duodéno-jéjunale
– Anastomosis “at the foot of the loop”
This change is very fashionable now, and is the subject of numerous descriptions by the method coelioscopique.
