Abstract

Purpose

Obesity has become a pandemic nowadays. Bariatric surgery is increasingly performed to manage obesity. Currently, laparoscopic sleeve gastrectomy (LSG) is a widely accepted procedure given its feasibility and efficacy. Previous studies revealed conflicting results regarding the change of gastric emptying following sleeve gastrectomy. The primary aim of the present study is to assess gastric motor function by gastric emptying scintigraphy in a cohort of non-diabetic patients undergoing laparoscopic sleeve gastrectomy (LSG) for treatment of severe obesity.

Methods

This prospective observational study included 100 obese, non-diabetic patients attending the surgery clinic at Cairo University Hospitals and Al Azhar University Hospitals. LSG was performed following a standardized protocol, with no complications observed. All patients had gastric emptying scintigraphy done through a standard semisolid meal (250 kcal), marked with 0.5 mCiTc 99, pre-operatively and 3 months after LSG.

Results

The mean age was 38.71 years (9.2) and males comprised 57% of the cohort. The body mass index, low-density lipoproteins, and glycated hemoglobin declined significantly at 3-month postsurgery. The scintigraphy study revealed a significantly reduced percent retention at equivalent time points 3 months after LSG. In addition, the percent of patients suffering from GERD decreased significantly after LSG.

Conclusion

Gastric emptying becomes faster after LSG in morbidly obese non-diabetic patients. GERD symptoms improve after surgery.
