Abstract

Background: Obesity, a major health crisis, is significantly associated with increased mortality and various serious health conditions, leading to the rise of surgical interventions.

Aim of the work: To evaluate the effects of the distance of resection from the pyloric ring on changes in body mass index (BMI), estimated weight loss (%EWL), and food tolerance following laparoscopic sleeve gastrectomy (LSG).

Methods: This prospective, randomized trial involved 50 morbidly obese patients. Two approaches were compared: a total antral sacrifice starting 2 cm from the pylorus (Group A) and an antral preserving technique starting 5 cm from the pylorus (Group B).

Results: Preoperative data showed mean BMI as 47.29±6.07 kg/m² in Group A and 49.03±6.59 kg/m² in Group B. Three months post-surgery, BMI decreased to 38.78±4.98 kg/m² in Group A and 41.19±5.53 kg/m² in Group B. At 6 months, further reductions were observed, with Group A at 32.96±4.23 kg/m² and Group B at 35.01±4.70 kg/m². Both groups exhibited significant BMI reductions from baseline to three months (P<0.001). There were no significant differences in the two groups' food tolerance scores at three and six months after surgery (P = 0.284 and P = 0.185, respectively).

Conclusion: Both surgical techniques lead to significant weight loss and enhanced food tolerance without any significant differences in %EWL, BMI changes, or food tolerance among the groups. This indicates that the gastric resection distance from the pylorus in LSG does not significantly impact short-term outcomes in weight loss or food tolerance.
