SOARES, Pedro França da Costa; CARVALHO, Rita Barbosa de; CHAIM, Elinton Adami  y  CAZZO, Everton. Brown bowel syndrome: a rare malnutrition-related complication of bariatric surgery. Nutr. Hosp. [online]. 2019, vol.36, n.3, pp.743-747.  Epub 17-Feb-2020. ISSN 1699-5198.

Case report:

we present the case of a 44-year-old male who presented with uncontrollable diarrhea, severe protein-calorie malnutrition and multiple vitamin deficiencies, along with peripheral neuropathy ten years after classic biliopancreatic diversion (BPD). He underwent nutritional support and had the surgery converted to a Roux-en-Y gastric bypass, with an uneventful outcome. The histopathology of the resected bowel revealed lipofuscinosis of the muscular layer compatible with brown bowel syndrome.


brown bowel syndrome is a rare complication of malnutrition that can be observed after BPD. It is associated with vitamin E deficiency. After recovery with nutritional support, a reoperation that elongates the common channel, and thus minimizes the degree of malabsorption, should be indicated in these cases.
