Is the Morbidity Increased for Gastric Band Removal When the Band Is Placed Around the Esophagus?

Abstract

Introduction: Laparoscopic adjustable gastric band (LAGB) procedures declined worldwide in the recent years. In the majority of the national registers, the numbers of gastric band removal and revisions following LAGB have surpassed the implants. Still a good knowledge of different techniques is important for young bariatric surgeons to diminish the morbidity of revisional surgery. Methods: From January 2015 to December 2016, a total of 139 patients were retrospectively reviewed after undergoing a gastric band removal. The study included all consecutive patients who underwent a gastric band removal in this period of time with no exclusion criteria. Sixteen patients (18.8%) received the perigastric technique, 57 patients (67.1%) received the pars flaccid technique, 54 patients (38.8%) received bands with periesophageal technique, and for 12 patients (14.1%), the operative reports did not allow to identify the techniques used. In the present study, the operative times and the reported complications of the three main bands techniques were compared. Results: There were 124 women (89.2%) and 15 men (10.8%), with a median age of 44 years (range: 24-71). The overall mean preoperative body mass index was 34\u2009±\u20097.6\u2009kg/m2 (range: 22-52\u2009kg/m2), and the mean preoperative weight was 93.7\u2009±\u200924.9kg (range: 49-165\u2009kg). One hundred and seventeen patients (84.2%) had procedures performed on an out-patient basis. The overall mean operative time was 23.9\u2009±\u200913.7 minutes (range: 7-83 minutes). We recorded three cases of bleeding with one conversion to laparotomy. The overall percentage of complications in the entire series was 6.5%. No mortality was recorded. Conclusions: Our study regarding the band removal revealed that no correlation was found for operative morbidity among the three different types of bands. The only proven difference was the operative time, which was greater for periesophageal approach. For the latter one, a particular attention should be paid to the risk of injury for diaphragmatic or left suprahepatic vein.
