Necrotizing Enterocolitis in a patient post Roux-En-Y Gastric Bypass.

 Benjamin Schapira

A 42-year-old female patient (BMI 51.2) underwent RYGB. At 12 months follow-up she presented with diarrhoea, vomiting, tachypnoea and hypotension. She was severely acidotic (pH 6.9), white cell count (24x10⁹/L) and lactate (7.3U/L). CT presented dilated bowel most prominently at the upper jejunum and she subsequently underwent laparotomy for small-bowel resection, subtotal colectomy and end ileostomy. Intraoperatively, patchy necrotic segments of colon were noted. Postoperatively, her lactate increased to 10U/L, necessitating relook laparotomy for further bowel resection. Caecal and ascending colon samples showed ischaemic and necrotic areas with transmural inflammation and marked bacterial overgrowth with no evidence of vascular compromise. These features resembled acute NEC. Clostridium, Campylobacter, Salmonella, Shigella and vasculitis screening were negative. She had a slow recovery, requiring total parenteral nutrition and at 36 months follow-up she is making good progress.
