Abstract
Obesity is a pandemic health problem in both developed and developing countries and the costs of care continue to grow in parallel with the prevalence of the disease. This morbid condition leads to a high incidence of complications and a decrease in life expectancy, especially among younger adults.
Surgical treatment of morbid obesity results in significant sustained weight loss, which reduces obesity-related morbidity and increases survival compared with patients receiving optimal medical therapy.
The aim of this study is to compare between antral resection (gastrectomy 2 cm from pylorus) and antral preservation (gastrectomy 6 cm from pylorus) during laparoscopic gastric sleeve and its influence on the percentage of weight loss, postoperative complications and nutritional and elemental deficiencies.
This is a prospective randomized study that will be conducted in Ain-Shams University Hospitals bariatric surgery unit over 40 morbid obese patients with minimal follow-up of 12 months starting from September 2018 to September 2019. Patients were divided into 2 groups: group A: composed of 20 patients assigned to antral resection sleeve gastrectomy (gastrectomy 2 cm from pylorus). group B: composed of 20 patients assigned to antral preservation sleeve gastrectomy (gastrectomy 6 cm from pylorus).
The mean of Postoperative gastric emptying t1/2 was much delayed in group A mean t1/2 was 95.3 min. while mean t1/2 for group B was 30.85 min. and the difference between the groups was statistically significant (P=0.02).
The results of our study further highlight the need for more strong and long term randomized trials to compare between the two techniques in questions, as the data observed can differ between trials and still no definite stance is taken towards the antral size in LSG for obesity management.
We concluded that the surgical approach regarding the size of the antrum doesn’t matter from the safety and postoperative complications point of view, but it is still not clear whether or not there is a difference between antral resection and preservation regarding the weight loss; our study suggests that there is no significant difference in the weight loss after surgery during the first year of follow up.
