Area of Science:

  • Bariatric Surgery
  • Minimally Invasive Surgery
  • Obesity Treatment

Background:

  • Laparoscopic sleeve gastrectomy (SG) is a popular bariatric procedure.
  • High cost of linear staples limits SG in some regions.
  • Bipolar vessel sealer offers a potential cost-effective alternative for gastric division.

Purpose of the Study:

  • To evaluate the feasibility of a stapleless laparoscopic SG.
  • To assess the safety and efficacy of using a bipolar vessel sealer in SG.
  • To explore an alternative to expensive stapling devices in bariatric surgery.

Main Methods:

  • Prospective study of 9 morbidly obese patients (BMI 38.2 kg/m²).
  • Stapleless laparoscopic SG performed using a bipolar vessel sealer for gastric division.
  • Sleeve created over a 42 French bougie, closed with sutures. Data on surgical time, morbidity, and weight loss collected.

Main Results:

  • Mean operative time: 117 minutes; Mean hospital stay: 2.3 days.
  • No major morbidity; two cases of basal atelectasis resolved medically.
  • Mean excess weight loss of 78.4% after 6.8 months follow-up.

Conclusions:

  • Stapleless laparoscopic SG using a bipolar vessel sealer is a valid alternative when staples are unavailable.
  • This technique shows promise for treating morbid obesity in resource-limited settings.
  • Further large-scale studies with long-term follow-up are needed.
