Article Synopsis
- The study focused on liver retransplantation as the sole treatment for patients with irreversible graft loss, examining data from three medical centers over 30 years.
- It included 66 patients and identified hepatic artery thrombosis as the leading cause for retransplantation, with a significant portion occurring within 30 days after the first transplant.
- The findings revealed that survival rates after retransplantation were lower than those after the initial transplant, with various factors like male gender and higher MELD score linked to increased mortality.
Background: Despite its increasing popularity, laparoscopy is not the option for bariatric surgeries performed in the Brazilian public health system.
Aims: To compare laparotomy and laparoscopic access in bariatric surgery, considering aspects such as morbidity, mortality, costs, and length of stay.
Methods: The study included 80 patients who were randomly assigned to perform a Roux-en-Y gastric bypass.
Background: Laparoscopic cholecystectomy is the preferable treatment for chronic or acute cholecystitis. Some factors may increase the rate of laparoscopic conversion to open cholecystectomy and perioperative complications. The role of gender as a risk factor for laparoscopic cholecystectomy is controversial.

Purpose: To compare the polypropylene mesh (Marlex®) to Vicryl®, Parietex composite® and Ultrapro® meshes to assess the occurrence of adhesions in the intraperitoneal implantation.
Methods: Sixty Wistar rats were allocated into three groups: PP+V, in which all the animals received a polypropylene and a Vicryl® mesh; PP+PC, with the implantation of polypropylene and Parietex composite® meshes and PP+UP, in which there was implantation of polypropylene and Ultrapro®. Macroscopic analysis was performed 28 days later to assess the percentage of mesh area affected by adhesion.
Objective: to compare intraperitoneal adhesion formation in rats when using polypropylene and polypropylene with poliglecaprone meshes.
Methods: we used twenty male, Wistar rats, divided in two groups. In group 1, the rats received the polypropylene mesh on their right side and the polypropylene with poliglecaprone mesh on their left side.
