RESUMO
Introduction Bile duct injuries (BDIs) still occur during laparoscopic cholecystectomy. Although management of such complications is challenging, collaboration of a multidisciplinary team and development of treatment methods and materials often lead to the successful treatment. Materials and methods Medical records of 67 patients who have experienced bile duct injures after laparoscopic cholecystectomy were retrospectively reviewed. All injures were classified according to the European Association for Endoscopic Surgery ATOM classification and investigated by manifestation of the injury, surgical repair technique, early and late complications. Results In 28 (41.8 %) patients with partial divisions, the surgical treatment of BDI was completed with endoscopic retrograde cholangiopancreatography (ERCP) and stenting while in 14 (20.1%) cases, the defect of bile duct was closed by suture. End-to-end ductal anastomosis was performed for 6 (13.4%) patients with complete division while 19 (28.3%) patients underwent hepaticojejunostomy. We followed up 58 (92.1%) of 63 patients. The mean follow-up duration was 25.7 (3 - 123) months. Twenty-three (39.7%) patients were found with strictures. Discussion Intraoperative detection and management of BDIs is crucial to achieve good results. The routine intraoperative cholangiography and possibilities of repair by initial surgeons in peripheral hospitals remain controversial. Stenting with a covered self-expanding metal stent is promising for the patients with partial divisions of bile ducts. Initial hepaticojejunostomy is often a preferred treatment for transected bile ducts because of lower rate of anastomosis strictures. However, as end-to-end anastomosis is more physiological, and endoscopy allows successful management of the strictures, we suggest choosing this treatment when possible Recommendation for paperwork content: Classifying bile duct injuries according to the new ATOM classification may be useful in the decision of the most appropriate treatment in each case.

BACKGROUND: Ultrasound guided fine needle aspiration biopsy with cytologic analysis is an initial step in diagnostic of thyroid nodules. Unfortunately, up to 30% of biopsies are indeterminate and diagnostic surgery is required. The aim of this study was to estimate the diagnostic value of BRAF V600E mutation status combined with cytomorphological features for diagnosis of papillary thyroid cancer (PTC) in cytologically indeterminate thyroid nodules. METHODS: A prospective study analyzed patients who had ultrasound suspicious thyroid nodules, underwent fine needle aspiration and cytological examination, and were classified according to the Bethesda system. Patients from indeterminate diagnostic categories were examined for BRAF V600E mutation and 22 cytomorphological features, and underwent thyroid surgery. A binary logistic regression model was used to evaluate the diagnostic utility. RESULTS: A total of 219 patients met study criteria. After histological examination, 77 (35.2%) patients were diagnosed with PTC and 142 (64.8%) with benign nodular thyroid disease. According to logistic regression model, significant features for PTC diagnosis were: liquid colloid consistency, papillary structures, eosinophilic colloid bodies, and BRAF V600E mutation. Risk groups classified by this model have sensitivity of 80.5% (95% CI: 69.9 to 88.7), specificity of 99.3% (95% CI: 96.1 to 100), positive predictive value of 98.4% (95% CI: 89.8 to 99.8), negative predictive value of 90.4% (95% CI: 85.7 to 93.7), and accuracy of 92.7% (95% CI: 88.4 to 95.8) for PTC diagnosis. CONCLUSIONS: Evaluation of BRAF V600E mutation status combined with cytomorphological features for diagnosis of PTC in cytologically indeterminate thyroid nodules can significantly improve diagnostic accuracy and reduce the number of diagnostic operations (calculator available at www.ptc-calc.we2host.lt).
