Laparoscopic Sleeve Gastrectomy Changes in the Last Decade: Differences in Morbidity and Weight Loss

Abstract

Abstract

Purpose:

Aim is to report the learning curve and standardization process of Laparoscopic Sleeve Gastrectomy (LSG), describing the evolution in surgical technique and patient management in the authors' experiences.

Methods:

One hundred twenty-seven patients were divided in three Groups (A, B, and C), based on bougie size and technical details, and included 36, 46, and 45 patients, respectively.

Results:

Mean operative time in Groups A, B, and C was 201.5, 150.8, and 172 minutes, respectively. Conversion to open surgery occurred in 1 Group A case. Eleven postoperative complications (8.6%) were observed (1 Group A, 8 Group B, 2 and Group C). Mean hospital stay in Groups A, B, and C, was 7.1, 6.9, and 3.1 days, respectively. At a mean follow-up of 69.7 months (Group A), 33.3 months (Group B), and 14.8 months (Group C), mean postoperative body mass index is 32.6, 28.1, and 31.5 kg/m², respectively. Percentage estimated body mass index loss (%EBMIL) was 74.8% for Group A, 85.7% for Group B, and 68.1% for Group C.

Conclusions:

LSG is a safe and effective procedure. In the postoperative course, meticulous alertness to early warning signs of sepsis and aggressive patient management are mandatory to prevent mortality. The use of a larger bougie size was associated with weight regain.
