Laparoscopic reversal of mini-gastric bypass to original anatomy for severe postoperative malnutrition

Twenty-six of 2934 patients underwent a laparoscopic reversal of mini-gastric bypass (RMGB) after a mean delay of 20.9 ± 13.4 months due to severe malnutrition syndrome.

• At presentation, patients had a mean body mass index of 22 ± 4.4 kg/m and an albumin serum level of 25.5 ± 3.6 gr/L.
• Sixty-three percent of patients experienced at least one severe complication related to malnutrition, including severe edema and infectious complications.
• Surgical exploration revealed that 66.5% of patients had a biliary limb longer than 200 cm, and 34.6% reported bile reflux symptoms.
• Overall postoperative morbidity was 30.8%, with lower rates when the entire previous gastrojejunostomy was resected.
• After a mean follow-up of 8 ± 9.7 months, all patients showed complete clinical and biological regression of severe malnutrition despite weight regain in 61.5% of cases.
