Gastrojejunostomy in Roux-En-Y Gastric Bypass for Morbid Obesity: Linear Stapler Length Does Not Affect Mid-term
1Imperial College Weight Loss Centre, Imperial College Healthcare Trust, St Mary's Hospital, London, UK.
Background:
The purpose of this study was to compare whether different linear stapler lengths used to form the gastrojejunostomy during laparoscopic Roux-En-Y gastric bypass affects mid-term weight loss outcomes.
Materials And Methods:
A retrospective single center analysis was performed. Surgical technique was identical other than either a 35 or 45 mm linear stapler being used to form the gastrojejunostomy. Multivariate regression was used to assess the relationship between the different stapler lengths and weight loss outcomes 2 years following surgery.
Results:
Of the 97 patients identified, 67 (69.1%) were included in the study. There were 30 patients in the 35 mm group and 37 in the 45 mm group. The groups were comparable in terms of basic demographic data and preoperative weight characteristics. There was no significant difference in weight loss outcomes 2 years following surgery when comparing between the different linear stapler lengths.
Conclusion:
Thirty-five versus 45 mm linear stapler lengths does not affect mid-term weight loss outcomes.
