Clinical study of single-incision laparoscopic cholecystectomy

Abstract

We experienced 63 patients with non-inflammatory disease who underwent single-incision laparoscopic cholecystectomy (TANKO-LC). Herein we report the procedure of operation and the short-term results. We compared 63 cases of TANKO-LC with 109 cases of non-inflammatory conventional laparoscopic cholecystectomy (S-LC) within the same period. At first, our standard procedure was to insert multiple trocars in the abdominal cavity through a single wound ; now, we insert only a single trocar all cases. In the 63 cases investigation, 3 cases required trocar addition and one case converted to open surgery. Intra and postoperative complications were recognized in 2 cases (port-site infection). No significant complications were recognized. In comparing the TANKO-LC group and the S-LC group, the operation time was intentionally longer in the TANKO-LC group (TANKO-LC group : 118 min, S-LC group : 90 min), but there were no differences in the blood loss, the rates of intra and postoperative complications and the conversion rate. Laparoscopic cholecystectomy is a standard operation for gallbladder removal, but single-incision laparoscopic cholecystectomy is considered a useful operation with the same low operative complication rate yet more satisfactory cosmetic results
