Heinicke, JM; Schnueriger, B; Borbely, YM; Mueller, P; Candinas, D (2008). Distal Roux-en-Y gastric bypass for the treatment of morbid obesity. In: 95. Jahreskongress der Schweizerischen Gesellschaft für Chirurgie. Basel, Switzerland. 28.–30.5.2008.
Background:
Classical Roux-en-Y gastric bypass (cRYGB) is a combined restrictive and slightly malabsorptive operation. Excess-BMI-loss (EBMIL) in cRYGB is ~60%, but is diminished for super obese patients (BMI > 50 kg/m2). We therefore designed a modified, mainly malabsorptive distal RYGB (dRYGB).
Methods:
We report mid-term results after 77 consecutive dRYGB in which malabsorption is inversely related to the length of the common channel. The common channel was 100–150 cm long depending on preoperative BMI, the biliopancreatic limb was 100 cm long, which left >>250 cm for the alimentary channel. To avoid the potentially dangerous combination of malabsorption with sustained restriction the pouch size was increased to ~50ml and a 25 mm circular stapler was used for the gastro-jejunostomy.
Results:
33 open and later on 44 laparoscopic interventions have been performed. Median preoperative BMI was 50.2 kg/m 2. No severe intraoperative complications have been observed and no anastomotic
leakage was noted in the postoperative period. 5 patients needed balloon dilation of an anastomotic stricture. 3 marginal ulcers occurred at the gastrojejunostomy. The 54 patients with a follow-up time of over 12 months (median 24 months) showed an overall
median BMI-reduction of 17 to an actual median BMI of 31.6 kg/m2, corresponding to a EBMIL of 74.5%. Obesity-related comorbid conditions were significantly reduced or cured. Intermittent diarrhea or steatorrhea in 12 patients was easily treated by pancreatic enzyme
supplementation.
Conclusion:
dRYGB is technically more demanding than cRYGB, but shows excellent results in terms of weight-loss and therefore also in reduction of comorbidity especially in super-obese patients. Measuring all three limb lengths allows for a calibration of the malabsorption. The quality of food-intake being important to (super-) obese patients in terms of quality of life, a less restrictive pouch seems more adapted to them. Lifelong multidisciplinary follow-up is mandatory.
