Abstract

Introduction: Up to 30 % of patients who have undergone laparoscopic sleeve gastrectomy require revision surgery for inadequate weight loss, weight regain, and/or the development of severe upper gastrointestinal symptoms. The aim of this retrospective study was to evaluate the safety and efficacy of laparoscopic fundectomy (LF) in cases of a residual fundus/neofundus development regarding GERD symptoms.

Methods: The study group comprised 19 patients (17 female; mean BMI 35.4 kg/m(2)) divided into 2 groups. Group A (n = 10) patients with severe GERD and evidence of residual fundus/neofundus, Hiatal hernia with good results in terms of weight loss. Group B (n = 9) patients with severe GERD, a residual fundus/neofundus, inadequate weight loss or weight regain. Fundectomy was indicated when a residual fundus/neofundus was associated with severe GERD symptoms. The presence of a residual fundus/neofundus was assessed by a barium swallow and/or multislice computed tomography.

Results: No mortality or intra-operative complications occurred. Five postoperative complications occurred: 2 cases of bleeding, 1 mid-gastric stenosis and 2 leaks (10.5 %). All patients experienced improvements in their GERD symptoms and stopped PPI treatment. Group B exhibited an additional %EWL of 53.4 % at 24 months.

Conclusion: LF and cruroplasty is feasible and has good results in terms of GERD symptoms control and additional weight loss. The high rate of postoperative complications observed in this series remains a matter of concern. A re-sleeve procedure might be considered as an alternative to RYGB/DS conversion restricted to selected patients.
