Mini-Gastric Bypass by Mini-Laparotomy: A Cost-Effective Alternative in the Laparoscopic Era


Laparoscopic mini-gastric bypass (MGB) is being increasingly performed worldwide. Results of MGB by mini-laparotomy (minilap MGB) are hereby reported.


126 patients undergoing minilap MGB from October 2004 to October 2006, were reviewed at an academic institution.


Mean age was 35 ± 11.4 years (range 15–72), preoperative BMI was 44 ± 6.9 kg/m2 (range 35–61.8) and 80 (63.4%) were women. Co-morbidities were present in 42 (33.3%). Operative time was 144 ± 15.8 minutes (range 120–160) and length of hospital stay was 3.32 ± 0.62 days (range 2–18).There was no hospital mortality, and the inhospital complication rate was 4.7%. No anastomotic leakage occurred, and the incidence of wound sepsis was 2.3%. The mean total cost of the procedure was 3408 ± 547 USD (range 2967–6876). Five patients (3.9%) developed incisional hernias and 3 (2.3%) marginal ulcers. BMI at 6 months was 33.0 ± 3.1 kg/m2 (range 26.8–43.5, P < 0.001) compared with preoperative value. At 1 year, mean excess weight loss was 68.4% and comorbidities resolved in 85%.


Minilap MGB is a simple, safe, effective and low-cost gastric bypass. It represents an attractive cost-effective alternative to laparoscopic MGB.
