An international experience with single-operator cholangiopancreatoscopy in patients with altered anatomy.

Background and study aims The utility of digital single- operator cholangiopancreatoscopy (D-SOCP) in surgically altered anatomy (SAA) is limited. We aimed to evaluate the technical success and safety of D-SOCP in patients SAA. Patients and methods Patients with SAA who underwent D-SOCP between February 2015 and June 2020 were retrospectively evaluated. Technical success was defined as completing the intended procedure with the use of D-SOCP. Results Thirty-five patients underwent D-SOCP (34 D-SOC, 1 D-SOP). Bilroth II was the most common type of SAA (45.7 %), followed by Whipple reconstruction (31.4 %). Twenty-three patients (65.7 %) patients had prior failed ERCP due to the presence of complex biliary stone (52.2 %). A therapeutic duodenoscope was utilized in the majority of the cases (68.6 %), while a therapeutic gastroscope (22.7 %) or adult colonoscope (8.5 %) were used in the remaining procedures. Choledocholithiasis (61.2 %) and pancreatic duct calculi (3.2 %) were the most common indications for D-SOCP. Technical success was achieved in all 35 patients (100 %) and majority (91.4 %) requiring a single session. Complex interventions included electrohydraulic or laser lithotripsy, biliary or pancreatic stent placement, stricture dilation, and target tissue biopsies. Two mild adverse events occurred (pancreatitis and transient bacteremia). Conclusions In SAA, D-SOCP is a safe and effective modality to diagnose and treat complex pancreatobiliary disorders, especially in cases where standard ERCP attempts may fail.

Venous thromboembolism prophylaxis in inflammatory bowel disease flare-ups.

BACKGROUND: Inflammatory bowel disease (IBD) is a set of chronic inflammatory diseases associated with significant morbidity. Generally, IBD patients have twice the risk of venous thromboembolism (VTE) compared to healthy controls. VTE in IBD is associated with greater morbidity and mortality. This is compounded by the underutilization of pharmacological anticoagulation in hospitalized patients with IBD. One study showed that half the IBD patients who developed VTE were not receiving any thrombotic prophylaxis. METHOD: We carried out a retrospective chart review of VTE prophylaxis use and safety in patients admitted with IBD flare-up between 2014 and 2017. RESULTS: We evaluated 233 patients (mean age 36.7 years; 53.6% male). Of these patients, 55.2% were Caucasian and 40.5% were African American; 72.5% had Crohn's disease and 21% ulcerative colitis. About one-third of our patients were on chronic steroids. Pharmacological prophylaxis was used in 39.7% of the patients. This significantly correlated with male sex, recent surgery, history of VTE, smoking, and chronic steroid use. Meanwhile, hematochezia, aspirin use, and a history of gastrointestinal bleeding were correlated with less use of pharmacological prophylaxis. Patients receiving pharmacological prophylaxis showed no difference in the incidence of bleeding events. CONCLUSIONS: Multiple factors were associated with the use of pharmacological prophylaxis in hospitalized patients, including sex, steroid use, history of VTE events or gastrointestinal bleeding, and hematochezia. The incidence of major bleeding was not significantly greater in IBD patients receiving pharmacological prophylaxis.

Pulmonary vein thrombosis in a patient with polycythemia vera.

Pulmonary vein thrombosis (PVT) is a rarely encountered disease entity with varied clinical presentations. It is usually associated with lung carcinoma, lung surgeries and as a complication of the radiofrequency catheter ablation procedure for atrial fibrillation. Its clinical manifestations can vary from mild hemoptysis to lung infarction with hemodynamic compromise. A 76-year-old male presented with a 2-d history of pleuritic left sided chest pain. His past medical history included polycythemia vera, atrial fibrillation, coronary artery disease, pulmonary embolism and pulmonary hypertension. Chest radiograph was normal, troponins were normal and the 12-lead electrocardiogram did not show any ischemic changes. A computerized tomography pulmonary angiogram revealed a filling defect in the left lower lobe pulmonary vein. He was treated with subcutaneous enoxaparin and his symptoms improved. This case highlights a rare etiology of chest pain and the first reported case of the association of polycythemia vera and pulmonary vein thrombosis. A high index of suspicion is required for appropriate diagnostic work up. PVT can mimic pulmonary embolism. The diagnostic work up and treatment strategies depend on acuity of presentation.
