Suture line recurrence in the jejunal pouch after curative proximal gastrectomy for gastric cancer: report of two cases.

We report two patients with suture line recurrence in the jejunal pouch after curative proximal gastrectomy for gastric cancer. The first patient was a 60-year-old asymptomatic woman with gastric cancer (T2N0M0) after curative proximal gastrectomy with jejunal pouch interposition. She had to undergo a second resection for suture line recurrence in the jejunal pouch 12 months later. On examination of the resected specimen, histological examination revealed a moderately differentiated adenocarcinoma, which was similar to that of the primary tumor. The second patient was a 74-year-old man who was also diagnosed as having locoregional recurrences in the jejunal pouch after a curative proximal gastrectomy with an S-shaped pouch for gastric cancer (T2N0M0). Histological examination of the resected specimen revealed moderately differentiated adenocarcinoma, which had a similar histopathology to that of the primary tumor. During the first procedure, the jejunal pouch was formed using several disposable devices and the end-to-side esophagojejunostomy was performed with another circular stapler to avoid contamination through surgical instruments. Exfoliated cancer cells that may have detached from the primary tumor during the surgical procedures could have contributed to local recurrence along the longitudinal suture line of the pouch.
