Abstract Sleeve gastrectomy (SG) has become the primary surgical modality of treatment for obesity. This operation could be associated with motor gastric dysfunction and abnormal gastric emptying. The purpose of this prospective study is to present a comparison study of gastric emptying to solids after performing sleeve gastrectomy with two different techniques using scintigraphy. Prospectively; 26 morbidly obese patients were submitted for laparoscopic SG. Group A: 15 patients had sleeve gastrectomy started 7 cm from the pylorus and then vertical gastrectomy along a 40 French size tube. Group B: 11 patients have the sleeve started at 4 cm from the pylorus and then vertical gastrectomy along a 40 french size gastric tube. Gastric emptying of solids was measured by scintigraphic technique. Results of gastric emptying after SG is variable according to point of starting sleeve gastrectomy from the pylorus. At 4 cm it is associated with delayed emptying in 73% of patients and at 7 cm it is associated with accelerated emptying for solids in 87% of patients. These results should be considered to select the appropriate technique according to gender and preoperative foregut condition.
