[A Case of Transverse Colon Cancer Undergoing Laparoscopic Right Hemicolectomy after Distal Gastrectomy with Billroth Ⅱ Reconstruction].

A 79-year-old man was diagnosed with transverse colon cancer who had a history of distal gastrectomy and antecolic Billroth Ⅱ(B-Ⅱ)reconstruction for duodenal ulcer. We performed laparoscopic right hemicolectomy. Surgical findings indicated that the tumor was located in the center of the transverse colon. After we performed mobilization of right colon and lymph node dissection, we performed mobilization of left colon and we peeled off those adhesions with the jejunal limb and transverse colon mesentery. Then, we resected transverse colon and removed right hemicolon. We reconstructed a functional end-to-end anastomosis on the ventral side of the jejunal limb. The patient was discharged without complications on the 10th postoperative day. In post B-Ⅱ reconstruction cases, we can perform laparoscopic colectomy safely with preoperative CT confirmation and adequate colon mobilization.
