Single-Port Laparoscopic Distal Pancreatectomy: Initial Experience

Abstract

Introduction: 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. Materials and Methods: 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). Results: 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. Conclusions: 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.
