Laparoscopic sleeve gastrectomy is a recently developed technique for treating morbid obesity. Since it is a simple procedure, many bariatric surgeons have adopted it in recent years with good results. However, there is still no standard procedure across different surgical teams. We will discuss the more controversial aspects of the surgical technique: the size of the bougie, the beginning of the distal section, the section shape at the gastroesophageal junction, the necessity and manner of reinforcing the staple line, and the routine use of intraoperative leak testing.

The volume of the gastric remnant increased significantly during the first year after LSG. However, this increase was not associated with weight loss. Further prospective research with longer follow-up periods is needed to confirm or contrast the present results.

Laparoscopic sleeve gastrectomy is a safe and effective technique for the treatment of morbid obesity. Its use is associated with a significant reduction in the presence of comorbidities associated with obesity. Multicentre studies with a longer period of monitoring are required to confirm the efficacy and safety of this surgical technique.
