Longer Antrum Length Tied to Better Outcomes Following Gastrectomy

NEW YORK (Reuters Health) Mar 05 – Leaving an antral segment of 2.5 cm during pylorus-preserving gastrectomy (PPG) is associated with better postoperative outcomes than leaving a segment of only 1.5 cm, according to a report published in the February issue of The British Journal of Surgery.
Conventional distal gastrectomy can often lead to the dumping syndrome and to duodenogastric reflux. PPG can prevent these problems, but symptoms of gastric fullness can occur postoperatively resulting in poor food intake.

In the current study, Dr. Y. Nakane and colleagues, from Kansai Medical University in Osaka, Japan, investigated whether the length of the retained antral segment had any bearing on gastric fullness symptoms and food intake.

The study included 30 patients with early gastric cancer who underwent PPG. In 20 patients, the distal transection line was 1.5 cm proximal to the pylorus. In the remaining patients, the line was 2.5 cm proximal to the pylorus.

Six months after the procedure, 10 patients in the shorter antrum group complained of gastric fullness compared with only one patient in the longer antrum group (p < 0.05). …
