Single-port laparoscopic distal pancreatectomy: initial experience.

Abstract

Laparoscopic distal pancreatectomy has become the standard treatment of choice for pancreatic tail cystic and solid tumors when technically feasible. Technological advances have led to the development of single-port laparoscopic surgery, a safe alternative procedure. We present our experiences with single-port laparoscopic distal pancreatectomy. We retrospectively reviewed clinical records and compared clinical outcomes in 40 patients diagnosed with a pancreatic tail mass between 2007 and 2013 who received either conventional laparoscopic (n=28) or single-port laparoscopic distal pancreatectomy (n=12). The mean surgery time in the single-port group (279.8±53.0 minutes) was significantly longer than in the conventional group (186.9±86.6 minutes) (P=.001). The mean duration of postoperative hospital stay in the single-port group (12.2±5.4 days) was also significantly longer than in the conventional group (8.3±4.7 days) (P=.028). The spleen was preserved more in the conventional group (60.7%) than in the single-port group (33.3%), but the difference was not significant (P=.112). There were no significant differences in intraoperative blood loss, tumor size, conversion rate, or postoperative complications between the two groups. Blood loss and postoperative complications of single-port laparoscopic distal pancreatectomy are similar to those of conventional laparoscopic distal pancreatectomy. Single-port laparoscopic distal pancreatectomy can be performed safely and effectively in select patients with pancreas tail neoplasms, but is associated with a longer surgery time and postoperative hospital stay.
