BACKGROUND: The main side effect of long-term laparoscopic sleeve gastrectomy is the onset of severe gastroesophageal reflux disease (GERD).

OBJECTIVES: The aim of this study was to evaluate the effectiveness of gastric bypass conversion in controlling postsleeve GERD.

SETTING: University Hospital and Private Hospital, France and Private Hospital, Italy.

METHODS: This retrospective multicenter study included patients who underwent laparoscopic sleeve gastrectomy and suffered from postoperative GERD, who did not respond to medical treatment and were converted to laparoscopic Roux-en-Y gastric bypass. The study involved 2 French university hospitals, 4 French private centers, and an Italian public hospital.

RESULTS: A total of 80 patients were reviewed. Treatment of a hiatal hernia was performed during laparoscopic sleeve gastrectomy in 3 patients, while 19 patients were operated for hiatal hernia during conversion to bypass (P = .0004). Six months after surgery, 23 of 80 patients maintained reflux symptomatology with a daily frequency, for which continued proton pump inhibitor treatment was required. The persistence of GERD was significantly more frequent among patients with previous gastric banding (n = 19) compared with patients with no history of gastric banding (n = 4, P = .02). In other words, the likelihood of having poor clinical success from conversion of the sleeve to bypass because of intractable GERD was 3 times higher if the patient had a history of gastric banding (relative risk = 2.89, odds ratio = 3.69).

CONCLUSION: The results of this study show that, despite the conversion, the symptomatology of GERD does not always disappear, especially in patients with previous gastric banding.
