Acute abdomen due to strangulated intravesical hernia with incidental finding of kidney tumor: A case report and literature review.

Internal supravesical hernia is a rare type of internal abdominal hernia with overall incidence <4% of all internal abdominal hernias. The clinical diagnosis is a major preoperative diagnostic challenge for both the surgeon and the radiologist. It is a rare cause of small bowel obstruction, but in case of strangulation it can be fatal and it necessitates urgent surgical intervention. In this case study, we report a case of intravesical type of supravesical hernia in a 63-year-old man with acute intestinal obstruction and an accidental finding of a kid-ney tumor. In the article, we discuss the clinical picture, diagnosis, risk factors, treatment strategy and complications of this rare entity.

A prospective cohort study for prediction of difficult laparoscopic cholecystectomy.

INTRODUCTION: Difficult laparoscopic cholecystectomy (DLC) is a stressful condition for surgeon which is followed by greater risk for various injuries (biliary, vascular etc.) Preoperative factors that are related to DLC are landmarks for surgeon to assess the possibilities for overcoming difficulties and making early decision about conversion to an open surgery. In prospective cohort study we evaluated and defined the importance and impact of preoperative parameters on difficulties encountered during surgery, defined DLC, predictors of DLC and index of DLC. MATERIALS AND METHODS: All patients in the study were operated by the same surgeon. We defined the total duration of the operation as the time from insertion of Veress needle to the extraction of gallbladder (GB) and DLC as a laparoscopic cholecystectomy (LC) that lasted longer than the average duration of LC and the value of one standard deviation. RESULTS: Multivariate logistic regression analysis identified five predictors significantly related to DLC: GB wall thickness > 4 mm, GB fibrosis, leukocytosis ˃10 × 109 g/L, ˃ 5 pain attacks that lasted longer than 4 h and diabetes mellitus. The sensitivity of the generated index of DLC in our series is 81.8% and specificity 97.2%. CONCLUSION: Preoperative prediction of DLC is important for the surgeon, for his operating strategy, better organization of work in operating room, reduction of treatment expenses, as well as for the patient, for his timely information, giving a consent for an operation and a better psychological preparation for possible open cholecystectomy (OC).
