Is Endoscopy Really Necessary for Placing Intragastric Balloons?

Intragastric balloons for obesity: critical review of device design, efficacy, tolerability, and unmet clinical needs

INTRODUCTION

Sustaining a healthy weight is a challenge and obesity, with associated risk of co-morbidities, is a major public health concern. Bariatric surgery has shown a great promise for many where pharmacological and lifestyle interventions failed to work. However, challenges and limitations associated with bariatric surgery has pushed the demand for less invasive, reversible (anatomically) interventions, such as intragastric balloons (IGBs).

AREAS COVERED

This review critically appraises IGBs used in the past, present, and those in clinical trials, discussing the device designs, limitations, placement and removal techniques, patient eligibility, efficacy, and safety issues.

EXPERT OPINION

Several intragastric balloons were developed over the years that brought excitement to patients and healthcare professionals alike. Albeit good efficacy, there had been several safety issues reported with IGBs such as spontaneous deflation, intestinal occlusion, gut perforation, and mucosal ulcerations. This led to evolution of IGBs design; device material, filling mechanism, fluid type, inflation volume, and further innovations to ease ingestion and removal of device. There are some IGB devices under development aimed to swallow like a conventional pill and excrete naturally through defecation, however, how successful they will be in clinical practice in terms of their efficacy and tolerability remains to be seen in the future.

The Safety and Efficacy of Procedureless Gastric Balloon: a Study Examining the Effect of Elipse Intragastric Balloon Safety, Short and Medium Term Effects on Weight Loss with 1-Year Follow-Up Post-removal

INTRODUCTION

The Ellipse intragastric balloon (EIGB) is a new swallowable balloon that does not require endoscopy at insertion or removal. The aim of this study is to investigate the safety of EIGB and its efficiency in weight reduction even after 1 year of expulsion.

METHOD

Prospective study on our initial experience with a consecutive group of patients who underwent the insertion of EIGB in the period between September 2016 and February 2017. The patients were followed up to assess pain, nausea, and vomiting after procedure. As well as, the time of balloon extraction, route of extraction, and weight loss.

RESULTS

Total of 112 patients underwent EIGB placement. A 1-year follow-up was obtained on 85% of patients. Mean weight and BMI before the procedure 92.2 kg and 34.3 kg/m², respectively. One patient had small bowel obstruction. Six patients did not tolerate EIGB and three patients had early deflation. Total weight loss % (TWL%) 10.7, 10.9, and 7.9% at 3, 6, and at date of last follow-up. When data were stratified according to BMI into two groups: group 1 (BMI 27.5-34.9) and group 2 (BMI 35-49), the TWL% for group 1 at 3 months, 6 months, and last day of follow-up are as follows: 10.2%, 10.6%, and 8.8%, while it was 11.5%, 11.2%, and 6.6% for group 2.

CONCLUSION

EIGB are effective, safe, and feasible non-invasive method for weight loss.
