Long-term comparative study on open versus laparoscopic biliopancreatic diversion

Area of Science:

• Bariatric surgery
• Obesity treatment
• Surgical techniques

Background:

• Morbid obesity is a growing epidemic requiring effective treatment.
• Bariatric surgery, specifically Scopinaro's biliopancreatic diversion (BPD), is a primary intervention.
• Evaluating laparoscopic versus open approaches for BPD is crucial.

Purpose of the Study:

• To assess the impact of laparoscopy on weight loss parameters in morbidly obese patients.
• To compare early and late complications between open and laparoscopic BPD.
• To evaluate the effectiveness of laparoscopic biliopancreatic diversion.

Main Methods:

• A longitudinal retrospective study of 277 patients undergoing BPD (1999-2015).
• Comparison between open BPD and laparoscopic BPD groups, with laparoscopy introduced in 2006.
• Assessment of operative time, blood loss, hospital stay, and complications (Clavien-Dindo classification).

Main Results:

• No significant differences in mean age (43.9 years) or BMI (52.5 kg/m²).
• Laparoscopic BPD showed a statistically significant reduction in hospital stay.
• Laparoscopic BPD demonstrated a significant decrease in incisional hernia incidence.

Conclusions:

• Laparoscopic biliopancreatic diversion (BPD) is a safe and effective bariatric procedure.
• The laparoscopic approach leads to a shorter hospital stay than open surgery.
• Laparoscopic BPD significantly reduces the incidence of incisional hernias.
