This study evaluated a new vertical-banded gastroplasty technique to reduce staple line complications. While reducing perforations, long-term weight loss success varied by initial BMI, and reoperation rates remained high.

Area of Science:

  • Bariatric surgery
  • Surgical innovation
  • Obesity treatment

Background:

  • Staple line perforations are a major cause of failure in vertical-banded gastroplasty (VBG).
  • A novel VBG technique was developed to eliminate reliance on staple lines, aiming to prevent this complication.

Purpose of the Study:

  • To assess the efficacy and long-term outcomes of a modified VBG procedure designed to avoid staple line complications.
  • To evaluate the impact of initial body mass index (BMI) on weight loss success and complication rates.

Main Methods:

  • One hundred two patients with BMI > 35 kg/m2 underwent the modified VBG with a specific orifice size.
  • The procedure involved division between vertical staple lines to prevent fistulas.
  • Ninety-eight patients were followed for a minimum of 4 years.

Main Results:

  • Sixty-two percent of patients achieved excellent or good results (BMI < 35 kg/m2 or < 50% excess weight) after 4.5 years.
  • Success rates were higher in obese (90%) versus morbidly obese (75%) and superobese (30%) patients.
  • Staple line disruption was reduced, but reoperation was needed in 36% due to stenosis, weight loss failure, or late weight gain.

Conclusions:

  • The modified VBG reduced staple line complications but did not eliminate the need for reoperation in a significant portion of patients.
  • Gastric bypass is considered superior to gastroplasty revision for remedial operations.
  • The study questions the overall long-term value of VBG in obesity treatment, even with improved staple line integrity.
