Abstrakt: Introduction and Objectives: Laparoscopic splenectomy and esophagogastric devascularization (LSED) are minimally invasive, effective, and safe in treating esophageal-fundic variceal bleeding with portal hypertension (PHT). The study aimed to assess the learning curve of LSED by cumulative summation (CUSUM) analysis. The 10-year follow-up data for LSED and open surgery were also examined.
Patients and Methods: Five hundred and ninety-four patients were retrospectively analyzed. Operation time, intraoperative blood loss, open operation conversion, and postoperative complications were selected as the evaluation indicators of surgical ability. The learning curve of LESD was assessed by the CUSUM approach. Patient features, perioperative indices, and 10-year follow-up data were examined.
Results: Totally 236 patients underwent open surgery, and 358 underwent LSED. Patient characteristics were similar between groups. The LSED patients experienced less intraoperative blood loss, fewer complications, and faster recovery compared to the open surgery cohort. The learning curve of LESD was maximal for a case number of 50. Preoperative general characteristics were comparable for both stages. But the skilled stage had decreased operation time, reduced blood loss, less postoperative complications, and better recovery compared to the learning stage. The LSED group had higher recurrent hemorrhage-free survival rate and increased overall survival in comparison with cases administered open surgery in the 10-year follow-up. Free-liver cancer rates were similar between two groups.
Conclusions: About 50 cases are needed to master the LSED procedure. Compared to open surgery, LSED is a safer, feasible, and safe procedure for PHT patients, correlating with decreased rebleeding rate and better overall survival.
