A Simple Technique of Tunnel Constructing for Occluding Splenic Vessels During Laparoscopic Splenectomy in Patients with Cirrhosis.

Purpose: Dissecting and ligating the splenic artery is crucial for bleeding control during laparoscopic splenectomy (LS). However, for patients with portal hypertension from liver cirrhosis, it is difficult for identification and ligation because the splenic vessel is circuitous and dilated. The aim of this study was to describe a simple technique of constructing a tunnel behind the tail of the pancreas for occluding the splenic vessels during LS in patients with portal hypertension. Materials and Methods: The clinical data of 61 patients who underwent LS from April 2016 to January 2017 were retrospectively analyzed. In 27 patients, the tunnel construction (TC) behind the tail of the pancreas approach was performed owning to difficulty in dissecting and ligating the splenic artery (TC group), including 17 patients who received the TC method directly and 10 patients who received the TC method after trying to dissect the splenic artery. The remaining 34 patients underwent traditional ligating of the splenic artery (LA group). The peri- and postoperative outcomes of operative time, blood loss, conversion rate, postoperative oral diet intake, postoperative hospital stay, and postoperative complication rate of the two groups were analyzed. All the operations were completed by the same group of surgeons. Results: All 61 operations were successfully completed. Compared with patients in the LA group, patients in the TC group had less blood loss (120.37 ± 40.74 mL versus 162.65 ± 87.47 mL; t  = -2.317, P  = .024). There was no statistical difference of operative time, conversion rate, complication rate, postoperative hospital stays, and follow-up between the two groups. Conclusions: The technique of constructing a tunnel behind the tail of the pancreas for occluding the splenic vessels was effective and safe in those patients whose splenic artery was difficult to dissect and ligate.
