Non-surgical Management of a Malecot Tube Migrating From a Small Bowel Fistula.

Foreign bodies are encountered relatively often within the practice of general surgery. We present a unique case of a rubber, self-retaining, radiopaque "mushroom-tip" Malecot tube placed for fistula drainage control due to an enterocutaneous fistula (ECF) that became a gastrointestinal foreign body.  A 24-year-old male presented in shock with gunshot wounds to his right chest and right upper abdomen to a Level I trauma center. He required a prolonged hospital stay with additional urological and thoracic procedures and an interventional radiology procedure for hepatic pseudoaneurysm and subsequently developed an ECF. The patient was discharged to a rehabilitation facility with a wound management system (WMS) for ECF drainage but returned to the clinic with chemical burns and skin excoriation due to poorly controlled output and suboptimal WMS fit. A better fitting WMS was employed and a 20-French Malecot catheter was placed to assist with drainage control. The patient later returned with abdominal pain reporting the Malecot advanced forward spontaneously and was not externally visible. CT scan revealed the Malecot across the prior ileocolic anastomosis. After considering potential treatment options, we initially proceeded with aggressive bowel stimulation, and saline enemas hoping the tube would pass through his colostomy. He was discharged and the catheter passed at home a few days later via the stoma. Gastroenterological literature recommends invasive management for sharp, corrosive, or elongated foreign bodies exceeding 6cm in length. This unusual case demonstrates a 30-centimeter (cm) blunt object passing through the small bowel and colon in the absence of an ileocecal valve.

MultiCenter Study of Intra-Abdominal Abscess Formation After Major Operative Hepatic Trauma.

INTRODUCTION: One of the significant complications of operative liver trauma is intra-abdominal abscesses (IAA). The objective of this study was to determine risk factors associated with postoperative IAA in surgical patients with major operative liver trauma. METHODS: A retrospective multi-institutional study was performed at 13 Level 1 and Level 2 trauma centers from 2012 to 2021. Adult patients with major liver trauma (grade 3 and higher) requiring operative management were enrolled. Univariate and multivariate analyses were performed. RESULTS: Three hundred seventy-two patients were included with 21.2% (n = 79/372) developing an IAA. No difference was found for age, gender, injury severity score, liver injury grade, and liver resections in patients between the groups (P > 0.05). Penetrating mechanism of injury (odds ratio (OR) 3.42, 95% confidence interval (CI) 1.54-7.57, P = 0.02), intraoperative massive transfusion protocol (OR 2.43, 95% CI 1.23-4.79, P = 0.01), biloma/bile leak (OR 2.14, 95% CI 1.01-4.53, P = 0.04), hospital length of stay (OR 1.04, 95% CI 1.02-1.06, P < 0.001), and additional intra-abdominal injuries (OR 2.27, 95% CI 1.09-4.72, P = 0.03) were independent risk factors for IAA. Intra-abdominal drains, damage control laparotomy, total units of packed red blood cells, number of days with an open abdomen, total abdominal surgeries, and blood loss during surgery were not found to be associated with a higher risk of IAA. CONCLUSIONS: Patients with penetrating trauma, massive transfusion protocol activation, longer hospital length of stay, and injuries to other intra-abdominal organs were at higher risk for the development of an IAA following operative liver trauma. Results from this study could help to refine existing guidelines for managing complex operative traumatic liver injuries.
