Abstract
Case 1 was a 2-year-old male with a polyp (2.5×2cm) in the middle portion of the descending colon. Case 2 was a 12-year-old male who underwent interval appendectomy 2 months after acute appendicitis. We performed an operation for the two childhood cases using single incision laparoscopic surgery. After a Y-shaped skin incision consisting of an underumbilical incision from 9 to 3 and a midline incision (slightly less than 1cm) on the umbilical caudal side, an SILS^<TM> port was inserted. The pneumoperitoneal pressure was 8mmHg, and a rigid laparoscope (5mm, 30°), REAL HAND^[○!R] with a movable tip, and general 5-mm forceps were used. In case 1, the descending colon was mobilized under laparoscopy by sharp and blunt dissections from the retroperitoneum. In case 2, the adhering appendix was dissected, and the mesoappendix was coagulated and resected. In both patients, the SILS^<TM> port was removed, and pulled out of the abdominal cavity through the same area. In case 1, the intestine was incised, and the polyp was resected under direct vision. In case 2, the appendix was resected, and the cut end was buried with purse string sutures. The operation time was 90 minutes in case 1 and 80 minutes in case 2. Both patients were discharged without complications 6 and 4 days, respectively, after the operation. We thought that single incision laparoscopic surgery from the navel is more difficult than conventional laparoscpic surgery but superior cosmetically.
