Aim: Relations between laparoscopic adjustable gastric banding (LAGB), gastroesophageal reflux (GER) and hiatal hernia (HH) are controversial. In this context the role of preoperative investigations to assess upper gastrointestinal (GI) function and its impact on the approach to LAGB and outcomes remains unclear. The aim was to define the value of preoperative upper GI testing, and to relate the findings with postoperative outcomes.
Methods: Seventy-eight cases were enrolled among 250 patients undergoing LAGB from January 2010 to December 2011 in our Center for the Multidisciplinary treatment of severe obesity. Patients were submitted preoperatively to endoscopy and radiologic series with oral contrast to assess the state of upper GI mucosa, the presence of HH, GER or cardias incontinence. According to the findings, patients were assigned to group A, if one or both exams showed positive results; or to the control group B if both exams were negative.
Results: GI series showed GER in 14.1% of patients, HH in 6.4%, altered motility in 5.1%, gastritis in 3.1%and were negative in 75.6%. Endoscopy showed gastritis in 71.8%of patients, HH in 30.8%, esophagitis in 7.7%, duodenitis in 7.7%, LES incontinence in 8%; while only 21.8% of patients had a negative exam. Differences between group A and B are not statistically significant in terms of pre- and post-operative BMI, EBWL%, long-term complications, time and number of regulations.
Conclusion: Positive findings in preoperative testing rarely postpone or change the surgical approach and postoperative outcomes. Our results encourage the omission of upper GI series from routine evaluation protocol prior to LAGB.
