Abstract
Background: Obesity is one of the leading preventable causes of death worldwide and with rates of adult and childhood obesity increasing, authorities views it as one of the most serious public health problem of the 21st century.
Aim of the Work: This study aims to prospectively assess the physiological changes in gastric emptying after sleeve gastrectomy and determine the time needed for accommodation. Recommendation of prokinetic therapy may be reached after this study.
Methodology: This study includes 30 morbidly obese patients who fulfilled the criteria for bariatric surgery with BMI >40 or >35 with associated co-morbidities with failure of other methods of weight loss.
Results: This study includes thirty (30) patients 24 females and 6 males , with a mean age of 37.50±8.72 years (range, 23 - 50 ) who underwent laparoscopic sleeve gastrectomy .The mean preoperative body mass index BMI is 44.65±4.26 kg/m2 (range,40 - 53 ) and the mean preoperative body weight is 123.90±14.79 kg ( range, 105 - 155).
Conclusion: Gastric emptying was significantly accelerated after sleeve gastrectomy with application of tight bougi ( 36 french size) and preservation of the antrum. There was strong correlation between delayed gastric emptying and appearance of postprandial symptoms which subsided after prokinetic therapy. However, further studies are required for comparison between tight and wide bougi as regards their effect on gastric emptying and weight regain.
