Laparoscopic revisional surgery after malabsorptive procedures in bariatric surgery, more specifically after duodenal switch.

Laparoscopic revisional surgery for both biliopancreatic diversion and duodenal switch is not a frequent event, and literature is sparse. Nevertheless, like any other weight loss surgical procedures, weight gain is possible or aggressive weight loss combined with micronutrients malnutrition may oblige surgeons to revise these original procedures. Reintervention strategies may include surgical improvements, conversion to other surgical procedures, or reversal. Revisions after duodenal switch are usually around 5% and may involve performing a re-sleeve or an elongation of the common channel at the expense of the biliopancreatic limb.
