Several studies suggest patients with a body mass index of 60 have a greater operative risk.
This requires 2 separate operations and all associated risks.
Dr Deborah Abeles and colleagues from Massachusetts, USA analyzed their experience in this population with a single-stage laparoscopic Roux-en-Y gastric bypass.
The research team compared 95 patients with a body mass index of 60 with 1311 patients with a body mass index less than 60 undergoing laparoscopic Roux-en-Y gastric bypass from 2001 to 2007.
Data recorded included age, body mass index , estimated blood loss, operating time, length of stay, and complications within the first 30 days after operation.

Analyses of the data were performed using unpaired Student's t-test, with p < 0.05 as significant.
The researchers found that there were no statistically significant differences in age, estimated blood loss, length of stay, overall complications, or 30-day mortality for patients with body mass index less than 60 as compared with patients with body mass index 60.
The difference in operating time between the 2 groups was statistically significant but likely reflected the learning curve.
Dr Abeles’ team concluded, “In our experience, there were no differences in the incidence of complications or mortality for patients with a body mass index of 60 undergoing laparoscopic Roux-en-Y gastric bypass as compared with those with a body mass index less than 60.”
“These high-risk patients can safely undergo a single-stage laparoscopic Roux-en-Y gastric bypass.”
