[Comparative scintigraphic functional study of 3 different reconstruction technics following total gastrectomy]

Area of Science:

• Gastroenterology
• Surgical Oncology
• Medical Imaging

Background:

• Total gastrectomy necessitates esophago-jejunal reconstruction.
• Common reconstruction techniques include interposed jejunal loop, Roux-en-Y loop, and "omega" loop with Braun anastomosis.

Purpose of the Study:

• To compare the functional outcomes of three esophago-jejunal reconstruction techniques after total gastrectomy for cancer.
• To determine which technique most closely replicates the function of an unoperated stomach.

Main Methods:

• Three groups of 15 patients each, who underwent total gastrectomy for Stages I-III cancer, were assessed.
• Esophago-jejunal transit, cholangio-scintigraphy, and biliary acid absorption tests were performed 4-10 months post-surgery.
• A control group of 10 healthy individuals was included for comparison.

Main Results:

• The interposed jejunal loop (Mouchet) demonstrated functional results closest to the unoperated stomach.
• Comparative data supported the superiority of the interposed jejunal loop technique.

Conclusions:

• The interposed jejunal loop (Mouchet technique) is the preferred method for esophago-jejunal reconstruction after total gastrectomy.
• This technique offers the most natural functional outcome compared to Roux-en-Y or "omega" loop reconstructions.
