552. LAPAROSCOPIC RE DO FUNDOPLICATION

Laparoscopic fundoplication though an effective form of therapy for patients with refractory gastroesophageal reflux disease, can fail due to poor patient selection or compromised surgical technique. Redo laparoscopic fundoplication is a challenging task prone to further failures. Retrospective analysis of consecutive patients who underwent laparoscopic redo fundoplication in a tertiary care center between July 2015 and March 2022. There were a total of 24 patients that underwent redo fundoplication during the study period. Wrap migration was noted in 8 (33.3%) patients while the wrap was too tight which led to dysphagia in 5 (20.8%) patients. Two patients had previously undergone laparoscopic redo fundoplication while one patient initially underwent open Nissen’s fundoplication. All the patients were managed successfully laparoscopically without any conversion. The median time interval between the first surgery and the redo operation was 8 months (3 months to 12 years). Symptomatic improvement was observed in 20 (83.3%) while 4 (16.7%) patients continued to have symptoms. Laparoscopic redo fundoplication can yield satisfactory results in patients after initially failed anti reflux surgery when performed in experienced centers. Proper case selection and meticulous surgical technique to address the primary cause of failure is paramount.
