Preoperative scoring system validation and analysis of associated risk factors in predicting difficult laparoscopic cholecystectomy in patients with acute calculous cholecystitis: A prospective observational study.

Objectives: Today laparoscopic cholecystectomy (LC) is the treatment of choice for acute cholecystitis. However, the presence of severe inflammation makes it challenging for the surgeons to accurately recognize the Calot's triangle which increases the risk of intraoperative complications. The aim of this study was to explore the validity of a scoring system used to predict difficult LC and to analyse the risk factors associated with difficult cholecystectomy in the setting of acute calculous cholecystitis.

Efficacy of hydrogastric sonography and spiral Computed Tomography in staging of gastric carcinoma--a comparative study.

Objective: Accurate preoperative diagnosis and staging of patients with gastric cancer is essential for optimal treatment. The standard of care for staging gastric carcinoma is helical CT. This study was conducted to compare the efficacy of hydrogastric sonography (HGS) with that of helical CT in the staging of patients with gastric carcinoma.
