RT Journal Article SR Electronic T1 An unusual case of caecal perforation following ileostomy reversal JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e229961 DO 10.1136/bcr-2019-229961 VO 12 IS 8 A1 Gamze Aksakal A1 Suat Ng A1 Vinna An YR 2019 UL http://casereports.bmj.com/content/12/8/e229961.abstract AB A 63-year-old man with a history of gastro-oesophageal reflux disease underwent defunctioning loop ileostomy for obstructing metastatic rectal cancer prior to receiving long-course neoadjuvant chemoradiotherapy. Four months post completion of neoadjuvant therapy, he underwent an uncomplicated elective ultra-low anterior resection with formation of colonic J pouch and first stage liver metastasectomy for bilobar liver disease. At 1 year, he proceeded to an elective closure of loop ileostomy. Unfortunately, his postoperative course was complicated by profuse diarrhoea with subsequent colonic perforation, necessitating an emergency laparotomy and ileocolic resection with end ileostomy formation. Histopathology and stool studies were consistent with Salmonella Typhi infection. At the present time, Salmonella Typhi causing toxic megacolon and subsequent colonic perforation is an uncommon phenomenon in Australia. Here, we present an unusual case and explain why bowel perforation in this instance likely had a multifactorial aetiology.
