Effectiveness and feasibility of laparoscopic distal pancreatectomy on patients at high anesthetic risk.

Abstract

Laparoscopic distal pancreatectomy (LDP) is the most acceptable procedure in laparoscopic pancreatic surgery. Nevertheless, knowledge regarding patients at a high anesthetic risk during lengthy and technically demanding LDP is controversial. This study aims to assess the feasibility and safety of LDP in patients with high anesthetic risk. We conducted a prospective collection retrospective review of patients underwent LDP and open distal pancreatectomy (ODP) from January 2011 until December 2013. By the American Society of Anesthesiologists score, patients were divided into low- and high-risk patients. We compared the clinical, perioperative, and postoperative results in these patients. The cohort included 77 patients: 20 underwent LDP, and 57 underwent ODP. There were 30 patients in the low-risk group and 47 patients in the high-risk group. In high-risk patients, LDP, compared with ODP, presented a shorter operating time (mean, 220.8±101.1 minutes versus 299.4±124.3 minutes; P=.038), less blood loss (409.3±569.9 mL versus 1083.1±1583.0 mL; P=.039), higher rate of spleen preservation (73.3% versus 43.8%, P=.037), and shorter length of postoperative hospital stay (LOS) (9.5±3.0 days versus 15.7±9.4 days; P=.044). In conclusion, LDP provides early recovery and better cosmetic appearance. In high anesthetic risk patients, LDP shows less operative time, less perioperative blood loss, a higher rate of spleen preservation, slighter complication, and shorter LOS, which might explain why LDP is a feasible and effective procedure.
