title: Hand-assisted laparoscopic hepatic resection.
abstract: Thanks to recent advances, performance of liver resection is now possible using laparoscopic procedures. However, still there are some difficulties to overcome. The hand-assisted method lends safety and reliability to the laparoscopic procedure. A 54-year-old man diagnosed with hepatocellular carcinoma (HCC) was referred for hepatectomy. Angiography with computed tomography (CT) scans revealed a 2-cm hepatocellular carcinoma (HCC) at segment V, close to the gallbladder. A hand-assisted laparoscopic hepatic resection was performed. Four 10-mm trocars, one for wall lifting and three for working, were placed in the upper abdomen. A small incision was added at the right side of umbilicus, and the operator's left hand was inserted through it. A microwave tissue coagulator and laparoscopic ultrasonic dissector were used for liver resection. Total operation time was 162 min; blood loss was 20 g. The postoperative course was uneventful, and the postoperative hospital stay was 7 days. We thus demonstrated that laparoscopic liver resection is safer and easier when the hand of the operator can be inserted into the abdomen. The small incision does not greatly diminish the benefits that accrue from minimally invasive laparoscopic surgery. The hand-assisted procedure allows better access to the tumor. In addition, hand assistance restores the sense of touch to the operator and is an effective means of controlling sudden and unexpected bleeding.
