Successful Laparoscopy-Assisted Resection of the Descending Colon in a Patient with Multiple Large Renal Cysts and Stricture of the Colon due to Ischemic Colitis

Large pathological structures in the abdominal cavity curb the application of laparoscopic surgery. This case report describes a successful laparoscopy-assisted colectomy for benign colon disease in a patient with multiple large renal cysts. An 82-year-old man was referred to our department for treatment of stenosis of descending colon secondary to ischemic colitis. An abdominal computed tomography revealed multiple large renal cysts occupying a large proportion of the peritoneal cavity. To minimize the postoperative recovery period, laparoscopic surgery was planned despite the renal cysts. After inserting access ports, the walls of the several renal cysts were fenestrated with an electronic scalpel and the serous fluid was aspirated to enable continuation of the laparoscopic colectomy. The left colon was mobilized and extracted through an incision at the umbilicus, and the affected part of the colon was resected safely. The patient's postoperative course was uneventful, and the present case suggests that laparoscopy-assisted colectomy can be performed safely even in patients with multiple large renal cysts.
