Indocyanine green in laparoscopic cholecystectomy: utility and correlation with a preoperative risk score.

Background: This study aims to compare the visualization of the cystic duct-common bile duct junction with indocyanine green (ICG) among 3 groups of patients divided according to the difficulty of elective laparoscopic cholecystectomy.

Methods: Conducted at a single center, this non-randomized, prospective, observational study encompassed 168 patients who underwent elective laparoscopic cholecystectomy and were assessed with a preoperative risk score to predict difficult cholecystectomies, including clinical factors and radiological findings. Three groups were identified: low, moderate, and high risk.

Need for a targeted perioperative antibiotic treatment protocol for patients with preoperative biliary drainage undergoing pancreaticoduodenectomy.

Purpose: To evaluate the bacterobilia in patients undergoing pancreaticoduodenectomy (PD) based on whether they carry a preoperative biliary drainage or not and to analyse if a targeted perioperative antibiotic treatment based on the expected microbiology leads in no differences in Surgical Site Infections (SSI) between the groups.

Methods: Retrospective observational single-center study of patients undergoing pancreaticoduodenectomy with preoperative biliary stent (group P, Prosthesis) and without stent (group NP, No Prosthesis). Postoperative complications including SSI and its subtypes were analyzed after applying a targeted perioperative antibiotic treatment protocol with cefotaxime and metronidazole (group NP) and piperacillin-tazobactam (group P).
