Bile Aspiration vs Drain in Acute Cholecystitis

In order to compare percutaneous cholecystostomy and leaving a drain in situ with percutaneous gallbladder aspiration we plan to undertake a double-blind randomized controlled trial.

Prevention of Postoperative Hernias in Emergency Surgery

The aim of this observational study is to understand the risk factors and incidence of postoperative hernias among patients undergoing emergency surgery. The main question it aims to answer is: What is the incidence of postoperative hernias in this group of patients? A brief telephone interview will be conducted with participants who will be included in this study one year after the surgery. If the presence of a postoperative hernia is suspected, the patient will be invited to a follow-up visit to the surgical clinic, where the diagnosis will be confirmed by imaging tests.

EOIB for Laparoscopic Cholecystectomy

Laparoscopic cholecystectomy, while less painful compared to conventional methods, is still a surgery that can cause significant pain for patients. Preventing postoperative pain is crucial for reducing respiratory complications, shortening hospital stays, and increasing patient satisfaction. Interfascial plane blocks have been widely used for postoperative analgesia in recent years worldwide. The External Oblique Intercostal Plane Block is one of the interfascial plane blocks used in abdominal surgeries. In our study, we aimed to compare the postoperative pain scores of patients who underwent laparoscopic cholecystectomy under general anesthesia, specifically between those who received the external oblique intercostal plane block and those who had trocar entry site infiltration.

Optimal Timing for Laparoscopic Cholecystectomy After Cholecystostomy in Acute Cholecystitis Tokyo II/III Setting

Percutaneous drainage in acute cholecystitis has been recommended by the recent update of the Tokyo Guidelines for patients with grade II and III disease who are unable to undergo surgical treatment due to their condition or associated comorbidities. There are no reports providing high-quality scientific evidence on the optimal timing for surgery after percutaneous transhepatic gallbladder drainage, so a consensus has not been reached. The grade III stage generates the most controversy; after percutaneous drainage, delaying the cholecystectomy can lead to new episodes of exacerbation during the waiting period or may limit the procedure to a specific group of patients with this pathology. The economic impact, including the number of readmissions, increased length of stay, and associated morbidity and mortality, generates controversy regarding the subsequent therapeutic decisions after the medical management of cholecystitis in this special group of patients.

Prospective Evaluation of Ultrasound-guided Percutaneous Cholecystostomy With the Trocar Technique

The purpose of this study is to further evaluate and investigate the safety and efficacy of ultrasound (US)-guided percutaneous cholecystostomy (PC) with the trocar technique by the patient's bedside.

Endosonography-guided Gallbladder Drainage vs Non-endoscopic Treatment in Inoperable Acute Cholecystitis

In this project the investigators propose to carry out a clinical trial that compares non-endoscopic treatment of cholecystitis with antibiotics versus endoscopic drainage in non-operable acute cholecystitism (AC), especially focused on the rate of subsequent EBP and recurrence of AC, as well as the impact on the quality of life, also exploring the costs. The ultimate goal of this project is to generate knowledge and scientific evidence that makes it easier for health professionals to choose the most appropriate strategy for non-operable patients with lithiasic AC. Ourworking hypothesis is that endoscopic treatment (EUS-GBD) will significantly reduce the number of EBP compared to non-endoscopic treatment in patients with non-operable lithiasic AC.
