department. Early diagnosis and treatment of AC has a positive effect on morbidity and mortality. Laparoscopic cholecystec- tomy (LC) is an important approach for treating acute cholecys- titis nowadays. Issued data indicated that approximately 917,000 and >50,000 LCs were annually performed to treat acute cholecystitis in the United States and England, respectively. Although LCs have been extensively performed to manage acute cholecystitis, the optimal timing of LC for this given con- dition is inconclusive. Aim of the work: The aim of this study is to prospectively com- pare between early and delayed laparoscopic cholecystectomy as a management of acute calcular cholecystitis along with their operative and post-operative outcomes. Patients and methods: From December 2019 to December 2020 in Ain Shams University Hospitals, a prospective randomized study was conducted over 20 patients of acute cholecystitis: 10 of them underwent laparoscopic cholecystectomy from 3 day to 7 day of symptoms of acute cholecystitis, and the other 15 after 6- 8 weeks. Operation time, intraoperative and postoperative surgical complications and duration of hospital stay were assessed and compared in the 2 groups. Results: Although the operation time was longer in the group with early laparoscopic cholecystectomy, but the overall com- Role Of Laparoscopy In Blunt Abdominal Trauma: A Comparative Prospective Cohort Study Between Laparoscopy And Laparotomy In Patients With Blunt Abdominal Trauma Tarek Ismail Ouf, Mohamed ElSayed ElShinawi, Ahmed Adel Abbas, Mostafa El Sayed Nagy General Surgery Department, Faculty of Medicine, Ain Shams University Background: Trauma is considered to be the main leading cause of death in young adults under 35 years old. Blunt mechanisms accounts for about 95% of injuries. Generally, laparotomy is con- sidered to be the standard procedure used in the trauma cases. Recently, laparoscopic techniques have been increasingly intro- duced as an alternative to open surgery in trauma cases. This study aims to assess the efficacy of Laparoscopy in manage- ment of patients with Blunt abdominal trauma in order to avoid unnecessary laparotomies. Objective: To investigate the effectiveness and role of laparo- scopy in the management of blunt abdominal trauma patients. Patients and Methods: Observational prospective cohort study.
