[A Case of Laparoscopic Sigmoidectomy for Sigmoid Colon Cancer after Open Total Cystectomy]

We report a case of laparoscopic sigmoidectomy for sigmoid colon cancer after open total cystectomy for bladder cancer. Case: A 73-year-old male with a history of open total cystectomy for bladder cancer was diagnosed with a type 2 lesion in the sigmoid colon during a lower gastrointestinal endoscopy for positive fecal occult blood. The preoperative diagnosis was cT3N0M0, cStage Ⅱa. A laparoscopic sigmoidectomy(D3 dissection)was performed. Considering the course of the ureter, we avoided dissecting the caudal side of the sacral promontory and prioritized mobilizing near the root of the IMA. Surgery was completed laparoscopically without damaging the ureter or ileal conduit. The patient was discharged on the 7th postoperative day after an uneventful recovery. Conclusion: We successfully performed laparoscopic surgery for sigmoid colon cancer using a magnified view and precise surgical maneuvers provided by laparoscopy. This case demonstrates the feasibility and safety of laparoscopic surgery in patients who have extensive adhesions from previous open surgeries, along with a review of relevant literature.
