Laparoscopic splenectomy and devascularization for massive splenomegaly in portal hypertensive patients: a retrospective study of a single surgical team's experience with 6-year follow-up data

BACKGROUND: In China, laparoscopic splenectomy and esophagogastric devascularization (LSED) are effective and safe tools that are used to treat esophageal-fundic variceal bleeding with portal hypertension (PHT) with minimal trauma; however, due to the increased difficulty of operation, their application in massive splenomegaly (MS) remains limited. This study sought to determine the efficacy and safety of LSED in treating MS patients with PHT. METHODS: The data of 124 patients who underwent LSED by a single surgical team at our department from January 2015 to December 2020 were retrospectively analyzed. The characteristics of the patients, perioperative parameters, and long-term follow-up data were examined. RESULTS: A total of 61 MS and 63 mild-to-moderate splenomegaly (MMS) patients underwent LSED. Much larger spleen and significant lower of white blood cells and platelets was found in MS group compared the MMS group preoperation (P
