ABSTRACT

OBJECTIVES: (1) To identify the factors predicting arterial extravasation in pelvic trauma and (2) to assess the efficacy of preperitoneal pelvic packing (PPP) in controlling arterial hemorrhage. METHODS: Institutional review board approved the retrospective study of 139 consecutive pelvic trauma patients who underwent angiographic intervention with or without prior PPP between January 2011 and December 2016. Patient demographics and presenting characteristics were recorded. Both groups of patients were combined for analysis of predictors for arterial extravasation using univariate logistic regression followed by multivariate logistic regression. Significance level was defined as p < 0.05. RESULTS: Forty-nine out of 139 patients had PPP prior to pelvic angiogram. Embolization was performed in 85 (61.2%) patients and the technical and clinical success rate was 100%. Sixty-nine (49.7%) patients had unstable Young-Burgess (Y&B) type fractures, of which 58% had arterial hemorrhage compared with 38.6% of those with stable Y&B fractures (p = 0.02). Of the patients who had PPP prior to angiogram, 28(57.1%) continued to have arterial extravasation on subsequent angiography. Unstable Y&B type fractures are independent predictors of arterial hemorrhage (OR 2.3, 95%CI 1.1 to 4.7, p = 0.02). CONCLUSION: Unstable Y&B type pelvic fractures are predictors of arterial extravasation. PPP alone is not effective for arterial hemorrhage control in pelvic trauma. Angiographic intervention remains a minimally invasive and definitive treatment of arterial hemorrhage from pelvic trauma. KEY POINTS: • Unstable Young-Burgess pelvic fractures are predictors of arterial hemorrhage in pelvic trauma. • Pelvic angiography and embolization should precede PPP wherever feasible.

ABSTRACT

INTRODUCTION: Biliary duct injuries pose a significant management challenge due to the propensity for recurrent biliary strictures. Development of a modified Roux-en-Y hepaticojejunostomy known as a Hutson-Russell Pouch (HRP) provides a point of entry for repetitive access to the biliary tree. We aim to highlight the effectiveness of using the HRP as an access point for the long-term management of anastomotic and distal biliary strictures, thereby showcasing the value in potential widespread adoption of this modification to a standard surgical procedure. MATERIALS AND METHODS: IRB-approved retrospective study of 36 patients (10 M, 26 F; mean age 55.19 ± 13.94; 15-83) underwent a total of 110 transjejunal cholangiograms. Indications for cholangiogram included cholangitis (n = 38), surveillance (n = 36), and elevated liver enzymes (n = 36). Technical success was defined by the ability to access and intervene in the biliary tree via HRP access. In case of stenosis, the ability to successfully dilate (< 30%) residual stenosis was considered a technically successful procedure. Clinical success was defined by normalization of the liver function tests or resolution of cholangitis. RESULTS: Technical success was achieved in 83/110 (75.45%) of the cases, and clinical success was achieved in 102/110 (98.2%). Transhepatic access was needed in 27/110 (24.5%) of the cases. Interventions performed included balloon cholangioplasty in 104/110 (94.5%), biliary stone removal in 2/110 (1.8%), biliary stent placement in 2/110 (1.8%), and biliary drain placement in 4/110 (3.6%). There were a total of 9/110 complications (8.2%). CONCLUSION: The HRP was an effective access point in the management of recurrent benign biliary strictures in this cohort.
