Abstract

Background

Capella surgery is one of the technical variations of Roux-en-Y gastric bypass. The method includes the preparation of an alimentary (Roux) limb with a standardized length (110 cm) in order to induce deficiencies in the absorption of macronutrients and thereby contribute to weight loss. The recognized variation in jejunoileal length in humans (approximately 4 to 9 m) is not considered, although this range correlates with the wide variation in the length of the common limb.

Methods

In order to assess the influence of variations in jejunoileal and common limb lengths on weight loss, intra-operative measurements were made of these segments on 100 patients undergoing Capella surgery. Patients were followed for a period of 1 year. Statistical analysis included subdivisions of the population by gender and body mass index.

Results

Average jejunoileal length was 671.4 ± 115.7 cm (434–990 cm). Average common limb length was 505.3 ± 113.3 cm (268–829 cm). No correlation was detected between jejunoileal length and weight loss at 6 months or 1 year following surgery. A weak negative correlation was detected between weight loss and common limb length at 1 year following surgery in male and super-obese patients.

Conclusions

Jejunoileal and common limb length vary widely in gastric bypass patients. To make modifications in the alimentary and/or biliopancreatic limb length, surgeons must consider the variability of the jejunoileal and common limb length.
