    Abstract:
    BACKGROUND: Conventional open and conventional laparoscopic splenectomy and azygoportal disconnection (CLSD) result in poor quality of life because of damage to the vagal nerve. We have developed vagus nerve-preserving laparoscopic splenectomy and azygoportal disconnection (VLSD). This study aimed to evaluate whether VLSD is effective and safe, and to determine whether a reduction in the incidence of postoperative complications improves postoperative quality of life compared with CLSD. METHODS: We retrospectively evaluated outcomes in 72 cirrhotic patients with portal hypertensive bleeding and secondary hypersplenism who underwent CLSD (n = 40) or VLSD (n = 32) between April 2015 and December 2016. Their demographic, intraoperative, and postoperative variables were compared. RESULTS: No patients required conversion to laparotomy in CLSD and VLSD. There was no difference in estimated intraoperative blood loss, volume of intraoperative blood transfused, time to first flatus, time to off-bed activity, and postoperative hospital stay between the two groups. VLSD was associated with a shorter operation time (P = 0.020) and less postoperative complications (P < 0.0001), including less diarrhea (P < 0.0001), epigastric fullness (P < 0.0001), and delayed gastric emptying (P < 0.0001), compared with CLSD. With VLSD, there was a significant increase in body weight and plasma albumin levels at 6 months postoperatively compared with preoperative values (all P < 0.05). The curative effect of improving esophageal/gastric variceal bleeding was similar in the groups. CONCLUSIONS: VLSD is effective and safe for reducing the incidence of postoperative complications, contributing to improving postoperative quality of life.
