NCT07478601
Postoperative pulmonary dysfunction is frequently observed after laparoscopic abdominal surgery due to the combined effects of general anesthesia, pneumoperitoneum, diaphragmatic dysfunction, and postoperative pain. These factors may impair respiratory mechanics, reduce lung volumes, and negatively affect postoperative recovery. Effective postoperative analgesia plays a crucial role in preserving respiratory function by allowing adequate ventilation and reducing pain-related respiratory limitation. The erector spinae plane (ESP) block is a relatively novel ultrasound-guided fascial plane block that provides thoracoabdominal analgesia through the spread of local anesthetic along the paraspinal fascial planes. By reducing postoperative pain and opioid consumption, ESP block may contribute to improved respiratory mechanics and preservation of postoperative pulmonary function. The aim of this prospective randomized controlled study is to evaluate the effect of ultrasound-guided erector spinae plane block on postoperative respiratory function and pain in patients undergoing elective laparoscopic cholecystectomy. Patients will be randomized into two groups: an ESP block group receiving bilateral ultrasound-guided erector spinae plane block and a control group receiving standard analgesic management. Postoperative respiratory parameters will be evaluated using spirometry measurements including forced expiratory volume in one second (FEV1), forced vital capacity (FVC), the FEV1/FVC ratio, and forced expiratory flow at 25-75% of the pulmonary volume (FEF25-75). In addition, arterial blood gas parameters and postoperative pain scores will be assessed and compared between the groups. The study aims to determine whether ultrasound-guided erector spinae plane block improves postoperative respiratory function and contributes to better postoperative recovery in patients undergoing laparoscopic cholecystectomy.
NCT05975385
The purpose is to find out if intraoperative acupuncture performed by needling PC 6 and LI4 point bilaterally, and Yin Tang point will help reduce the incidence postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy when added to a prophylactic regimen consisting of ondansetron and dexamethasone. The hypothesis is that the addition of this acupuncture treatment to ondansetron and dexamethasone given for prophylaxis will help reduce the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy when compared to patients receiving ondansetron and dexamethasone without acupuncture.

NCT06123117
This trial is a prospective randomized superiority trial comparing sole ropivacaine based local trocar site infiltration to local infiltration combined with laparoscopic ropivacaine TAP block (STALL) in LCC. There are only a few randomized trials comparing sole local anesthesia to additional laparoscopic TAP block in laparoscopic cholecystectomy and they have yet failed to show evidence in favor of TAP block. We hypothesize STALL (Single Transversus Abdominis Laparoscopy-guided plane block combined with Local trocar site ropivacaine infiltration) is superior to local port site infiltration, provided that the sample size is sufficiently big. The aim of this randomized study is to compare the efficacy of sole local anesthesia of trocar sites to STALL in LCC.
NCT07113704
This retrospective cross-sectional study evaluated the safety and effectiveness of the fundus-first laparoscopic cholecystectomy (FFLC) technique in patients with difficult gallbladders. A total of 124 patients who underwent FFLC between 2023 and 2024 were reviewed. The study assessed operative time, intraoperative complications, conversion rates, and postoperative outcomes. The results suggest that FFLC is a safe and feasible approach that can reduce the need for conversion to open surgery in complex cases. The study was conducted at a private hospital in Istanbul, Turkey
NCT07051980
Endoscopic retrograde cholangiopancreatography (ERCP) is a technique for evaluating the bile duct, pancreatic duct, and ampulla. Hypoxia is the most common cardiopulmonary complication during ERCP, with a reported rate of 16.2 to 39.2%. The key to preventing hypoxia is to ensure the sufficient oxygenation and ventilation of patients during these procedures. The commonly used approaches to treat hypoxia with a non-instrumented airway are increasing the oxygen flow and lifting the jaw, applying with both hands, displacing the jaw upwards and anteriorly, which allowed the upper airway to remain open. We hypothesized that the supraglottic oxygen delivery via an endotracheal tube can reduce the incidence of hypoxia in patients under deep sedation during ERCP.
NCT07021300
This study compares two different timing approaches for gallbladder removal surgery in patients with acute gallbladder inflammation (acute cholecystitis). When someone develops acute cholecystitis, doctors need to remove the gallbladder using a minimally invasive technique called laparoscopic surgery. However, there is ongoing debate about the best timing for this surgery. Some doctors prefer to operate early (within 3 days of diagnosis), while others prefer to wait and operate later (after 4 weeks of medical treatment). In this study, we randomly assigned 166 patients with acute cholecystitis to receive either: * Early surgery: Laparoscopic gallbladder removal within 72 hours of diagnosis * Delayed surgery: Laparoscopic gallbladder removal after 4 weeks of antibiotic treatment All surgeries were performed by the same experienced surgeon using standard techniques. We measured how long each surgery took, how many days patients stayed in the hospital, and how often the surgeon needed to switch from the minimally invasive approach to open surgery. The study found that patients who had early surgery had shorter operation times, went home from the hospital sooner, and were less likely to need open surgery compared to patients who waited 4 weeks for their operation. This research helps doctors and patients make better decisions about the timing of gallbladder surgery when someone has acute cholecystitis.

Laparoscopic cholecystectomy is done traditionally with four ports. It has been observed that the same could be achieved using three ports. In this study we will study the outcomes of laparoscopic cholecystectomy done with both techniques.
NCT06130163
At the Kepler University Hospital Linz all variants of ERCP (preoperative, intraoperative, postoperative ERCP) are performed in cases of simultaneous cholecysto- and choledocholithiasis. Hardly any other hospital in Austria prefers intraoperative ERCP or offers it at all. A standardized procedure with implemented logistics has been established. This study compares intraoperative and postoperative ERCP.
NCT06522308
Researchers aim to determine the exact prevalence and risk factors for the association of gallstones and umbilical hernia. Umbilical hernia is defined according to the European Hernia Society Classification for primary and incisional abdominal wall hernias as hernias occurring from 3 cm above to 3 cm below the umbilicus. The main outcome measures are the presence of gallstones in patients presenting with umbilical hernia and the presence of umbilical hernia in patients diagnosed with gallstones. Patients with umbilical hernia are examined with biliary ultrasound, while patients with cholelithiasis are evaluated for umbilical hernia by physical examination and ultrasound. Factors such as age, gender, body mass index (BMI), family history, comorbidities, tobacco use, parity, and history of multiple pregnancy are analyzed as potential risk factors.
NCT06244589
This retrospective controlled study aims to evaluate risk factors that affect open conversion in laparoscopic cholecystectomy. Patient characteristics, medical history, biochemical and radiological studies of the patient will searched from the hospital database and factors affecting open conversion will be analysed.
NCT05557669
Prospective cohort study. POPULATION: patients with gallstone disease qualified for laparoscopic cholecystectomy INTERVENTION: patients undergoing cholecystectomy for gallstones COMPARISON: gallstone disease without surgery in an observation period OUTCOME: metabolic syndrome symptoms evaluated in 3 months period The main inclusion criteria is cholelithiasis confirmed by ultrasound examination in patients between 18-75 years old. The main exclusion criteria are metabolic syndrome, diabetes, thyroid diseases, pancreatic diseases, serious abdominal surgeries in the past, pregnancy, and lactation. Participants who qualified for laparoscopic cholecystectomy in 3 months are included in the investigation group. Those not having cholecystectomy planned in the upcoming three months for any reason (no consent for surgery, long term) are included in the control group. The intervention is to assess all metabolic syndrome criteria (blood pressure, glucose tolerance, dyslipidemia, abdominal obesity) before and three months after surgery. The endpoint is to evaluate if the risk of metabolic syndrome after cholecystectomy is higher than in patients with gallstones.

NCT02149797
Cholecystectomy is one of the most common operation performed by general surgeons. Since, first video-laparoscopic cholecystectomy in 1987, laparoscopic cholecystectomy (LC) has become the gold standard treatment for benign biliary disease. In daily practice, LC has increased general surgeons familiarity to video-laparoscopic operations and has become the first step to search more minimally invasive techniques and to perform advanced laparoscopic operations. In order to move forward the minimal invasive surgery concept with less surgical trauma and better cosmetic results, surgeons firstly reduced the number of incision and ports, then the idea of totally eliminating skin incisions through the use of natural orifices was implemented in selected cases. In theory, minimal incision must provide minimal postoperative pain and better cosmetic results. With the use of single-incision laparoscopic cholecystectomy (SILC), this purpose is achieved by means of cosmesis but providing minimal postoperative pain is still controversial. Recent reports on, LC vs. SILC showed significantly favorable cosmetic benefit, comparable complication rate and hospital stay with SILC, but the mean operation time was significantly longer. Today, lack of standardized operation technique, the need for specialized instruments, the fear of inability to apply safe cholecystectomy principles, longer operation time, cost-effectivity and advanced laparoscopic experience are still limiting factor to performing SILC. The aim of this prospective randomized controlled trial is to compare gold standard LC and SILC using our new technique called "Pick'n roll" (SILC-PR). Our goal was to provide critical view of safety and safe cholecystectomy principles on SILC, improve operator ergonomics and shorten operation time while eliminating the need for specialized instruments.
