Abstract
PURPOSE: Children with chronic ulcerative colitis (CUC) are at increased risk for venous thromboembolism, especially after colectomy procedures. We aim to review our patients with CUC who underwent a colectomy and suffered intra-abdominal thrombosis; moreover we wanted to define thrombotic incidence and outcomes METHODS: In this is IRB approved retrospective study, we reviewed our patients who underwent colectomy for CUC from January 1999 to December 2011 for development of intra-abdominal thrombosis. RESULTS: Of 366 patients with CUC who underwent colectomy, 15 (4%) were diagnosed with a venous thromboembolism. All patients presented with acute abdominal pain. The locations of thrombus formation varied: 13 (87%) developed thrombi in the portal vein, 4 (27%) in the splenic vein, 2 (13%) in the superior mesenteric vein, 1 (7%) in the hepatic vein, and 1 (7%) in the hepatic artery. The mean number of post-operative days at diagnosis of thrombus was 38.7 days (range 3-180 days). Fourteen patients (93%) underwent anticoagulation for treatment. The mean number of days of anticoagulant therapy until documented resolution of thrombus on imaging was 96.3 days (range 14-364 days). All thrombi resolved with therapy. There was no mortality during follow-up. CONCLUSIONS: Four percent of our pediatric patients with chronic ulcerative colitis who underwent colectomy developed symptomatic intra-abdominal venous thromboembolism. 3 to 6 months of anticoagulant therapy is adequate treatment in almost all patients. Practitioners should have a high index of suspicion for intra-abdominal venous thrombus when these patients complain of abdominal pain postoperatively. Based on our experience, prophylactic anticoagulation should be strongly considered peri-operatively in this population.
