Active clinical trials for "Acalculous Cholecystitis"

The aim of this retrospective study was to assess the different outcomes of early (performed on the patient's first admission for acute cholecystitis) and delayed cholecystectomy (done on a second admission) at King Abdulaziz University Hospital in Jeddah, Saudi Arabia.

The ideal management of cholecysto-choledocholithiasis is an open cholecystectomy (OC) with the common bile duct (CBD) exploration worldwide. The single setting 2-stage approach- endoscopic retrograde cholangiopancreatography (ERCP), endoscopic sphincterotomy (EST), and CBD clearance followed by laparoscopic cholecystectomy (LC) offers an advantage, mainly by reducing the hospital stay, the cost, and the morbidity. Investigators did a prospective study in patients admitted for the management of the cholecysto-choledocholithiasis in the Department of Surgery at the Lumbini Medical College and Teaching Hospital from November 2012- October 2015. They underwent 2-stage ERCP+LC in a single setting and investigators compared them with 2-stage OC+CBD exploration in a single setting approach. The patients with the open procedure were the investigator's control groups. All the included cases in the study were elective.

The goal of this observational study is to compare the use of Airseal versus a standard insufflation, in children who underwent laparoscopic cholecystectomy, between January 2021 and December 2022. The main questions it aims to answer are: amount of analgesics consumed postoperatively mean digital pain scale Data are directly extracted from patients medical files. The investigators will compare the Airseal group (A group) to the Standard insufflation group (S group) to see if the A group consumes significatively less analgesics and are less painful than the S group.

Study is designed to investigate whether the history of ERCP is associated with subtotal cholecystectomy rates in patients underwent laparoscopic cholecystectomy operations with the diagnosis of acute cholecystitis.

Standard Pressure Laparoscopic Cholecystectomy，as the standard for cholecystectomy, can lead to about 15% of pulmonary atelectasis. According to literature, low pressure laparoscopic cholecystectomy is thought to probably decrease cardio-pulmonary related complications and postoperative pain. However, the previous studies have presented controversial results. Our study aim to evaluate the potential pulmonary benefit of low pressure laparoscopic cholecystectomy in elderly or patients accompanied with cardio-pulmonary disorders.

Acute calculous cholecystitis (ACC) is the second most frequent surgical condition in emergency departments, the complication rate of ACC is 20-55%, and the mortality rate is 0.5-15% in recent series. The Tokyo Guidelines (TG) advocate for different initial treatments of ACC with no clear evidence that all patients will benefit from them. The objective of the study is to identify the risk factors for mortality in ACC and compare them with TG classification. It is a retrospective cohort study conducted from January 2011 to December 2016 in a single center with a dedicated surgical emergency unit in a Metropolitan University Hospital in Barcelona, Spain. The analysis of the data was finished in March 2020. The study candidates comprised 963 consecutive patients with a diagnosis of ACC according to the TG18 and/or received a diagnosis of ACC in the Pathology report in those that an emergent cholecystectomy was performed. The study case definition was a 'Pure Acute Cholecystitis' (pure ACC); therefore, patients with any other concomitant diagnosis potentially influencing outcome (Postoperative cholecystitis, Acute Cholangitis, Acute Pancreatitis, Incidental Cholecystectomy, Acalculous Cholecystitis, Chronic Cholecystitis/Persistent Colic, Post-endoscopic retrograde pancreato-cholangiography, or Neoplasia) were excluded from the final analysis. Variables: Primary data were available from a prospective database maintained in File Maker v.12 (Mountainview, CA, USA), which included basic demographic data, type of interventions, sex, days of admission, and complications. Every record was completed by browsing the electronic patient record, adding laboratory and microbiology data, as well as antibiotic therapy, duration of procedure, additional procedures, and grade of acute cholecystitis according to the TG18 diagnostic criteria. Preoperative comorbidities were assessed using the Charlson Comorbidity Index and surgical risk by ASA classification. The type of initial treatment was classified as Surgical Treatment (Cholecystectomy either by laparoscopy or laparotomy) or Non-Surgical Treatment, which was either percutaneous cholecystostomy or intravenous antibiotics alone. The main outcome measure was the mortality after the diagnostic of ACC. In the patients that were discharged, 30 days after the diagnosis, if the patients was not discharged in 30 days, at any time during the same admission. Interventions: All patients received intravenous antibiotic therapy from the moment the diagnosis was formulated, according to a fixed protocol. Ultrasound-guided cholecystostomy was performed percutaneously with an 8-Fr catheter (SKATER ™, Argon Medical Devices, Rochester, NY, USA) by either transhepatic or transperitoneal insertion, at the discretion of the radiologist. Laparoscopic Cholecystectomy was performed according to the French technique using 4 trochars. The content of the gallbladder was evacuated by Veress needle puncture when necessary. Statistical Analysis: The normal distribution of the quantitative variables was assessed using the Kolmogorov-Smirnov test, which showed that none of the variables were normally distributed; therefore, their values were expressed as median and interquartile ranges. The Mann-Whitney U non-parametric test was used to assess the significance of differences between means. The association between qualitative variables was assessed with the chi-square test or Fisher's exact test, as required. The increased risk of an event associated with a variable was reported as the odds ratio (OR) and 95% confidence interval (CI). As this was a retrospective observational study and the treatment groups were markedly asymmetric, we used the propensity score matching method to select and compare two subgroups of patients evenly balanced by severity according to the TG18 criteria and by comorbidity according to the Charlson Comorbidity Index. A model for predicting mortality was built using binomial logistic regression with stepwise progressive conditional entry and standard baseline conditions for admission and rejection of variables with significant differences in the univariate analysis. The discrimination power of the model was assessed by receiver operating characteristic (ROC) curves and was compared with the DeLong method. Legal and Ethical considerations This study was approved by the clinical research ethical committee of the Hospital del Mar and was classified as a non-clinical trial.

In theory, increased vascularity of GB wall could be associated with intraoperative findings, such as, GB wall inflammation and accompanying adhesions. There are not enough reports in the literature describing the correlation between GB wall vascularity and operative findings according to adhesion scoring scale. In this prospective clinical study, we aimed to highlight the correlation between preoperative power Doppler sonography detected GB wall vascularity and intraoperative findings - postoperative outcomes of chronic and acute cholecystitis patients.

The aim of this study is: To describe the natural course of acute cholecystitis, by performing repeated ultrasound examinations from day of admission to hospital until day of surgery or discharge. To investigate if there is anything in the ultrasound picture that can predict a difficult operation. Patients will be prospectively enrolled. The ultrasound picture (ultrasound variables: gallbladder volume, gallbladder wall thickness, and presence of oedema in the gallbladder wall), will be compared to clinical variables (tenderness in right upper quadrant, WBC, CRP and temperature) and to the time (hours) from onset of symptoms. Statistical analyses will be made to see if statistically significant, and clinically relevant, associations between variables exist. Furthermore, for participants receiving acute surgery, an upper GI surgeon will evaluate the operation as easy, intermediate or difficult. In extension, investigators will look at associations between difficult surgery and all the variables previously mentioned (both ultrasound variables, clinical variables and time).

In this retrospective study, the investigators evaluate the relationship of post-ERCP-choledocholithiasis(PEC ) and the gallbladder status as a risk factor.

Percutaneous cholecystostomy is used to reduce the complications and mortality associated with surgery in patients with high surgical risk in acute cholecystitis. Although this method generally acts as a bridge treatment for interval cholecystectomy in patients, interval cholecystectomy is not performed in every patient after percutaneous cholecystostomy. The aim of this study was to determine the recurrence rate of patients who did not have interval cholecystectomy after treatment with percutaneous cholecystostomy and to investigate the factors that may affect the recurrence.
