Modified Laparoscopic Pyloroplasty During Laparoscopic Splenectomy and Azygoportal Disconnection for the Prevention of Postoperative Gastroparesis.

BACKGROUND: Gastroparesis is a common complication after splenectomy and azygoportal disconnection, remaining a chronic debilitating disorder with considerable treatment challenges. To minimize postoperative gastroparesis, we have developed a new modified laparoscopic pyloroplasty (LP) technique for use during laparoscopic splenectomy and azygoportal disconnection (LSD).

METHODS: We retrospectively evaluated the outcomes of 31 cirrhotic patients with portal hypertensive bleeding and secondary hypersplenism who underwent synchronous LSD with modified LP (n = 14) or LSD without modified LP (n = 17) between January 2015 and August 2015. Perioperative variables were compared.

RESULTS: LSD with and without modified LP were successful in all patients. Operation time was significantly longer for LSD with modified LP than LSD without modified LP ( P = .001). However, the LSD with modified LP group had significantly reduced incidences of bloating 1 month postoperatively ( P < .05), nausea ( P < .05), and bloating ( P < .05) 3 months postoperatively, gastric retention 3 months postoperatively ( P < .0001), and prokinetic use at 1 month ( P = .009) and 3 months postoperatively ( P < .05) compared with the LSD without modified LP group. Gastric emptying scintigraphy showed that the mean time required to empty 50% of the ingested meal was significantly shorter in the LSD with modified LP group than in the LSD without modified LP group at 3 months postoperatively (74.3 ± 19.1 vs 261.7 ± 61.0 minutes, P < .0001).

CONCLUSIONS: Modified LP during LSD was feasible, effective, and safe, and significantly reduced short-term symptoms of postoperative gastroparesis.
