Active clinical trials for "Cholecystitis, Acute"

The smoke produced by the electric section of the tissues during laparoscopy alters the vision of the operative field and presents potential risks. A new medical device with CE marking (Ultravision ©) has been developed to limit electroprecipitation on the wall and tissues of the abdomen. The aim of the work is to evaluate the effectiveness of this medical device in laparoscopic cholecystectomy for cholecystitis. It is an intervention for a common pathology where smoke is particularly important due to the tissue inflammation and due to the extensive dissection necessary to perform the surgical procedure. A randomized double-blinded study will be conducted in two academic hospitals (Marseille North Hospital and Timone, APHM) evaluating the use of a smoke electroprecipitation device (Ultravision ©) during laparoscopic cholecystectomy for cholecystitis operated at the acute phase. A group of 30 patients using the device will be compared to a control group of 30 patients. The evaluation will last thirty days per patient and the duration of inclusion is 2 years. The main objective is to demonstrate a significant reduction in operating duration by using the device. The secondary objectives are to reduce the CO2 consumption, the surgical incidents and the discomfort of the surgeon related to the smoke.

Meta-analysis of randomized controlled trials and population based studies in acute cholecystitis are in favor for early laparoscopic surgery versus a delayed operation several weeks later. The main problems in these studies are the exclusion criteria used, thus not reflecting the real world setting of acute cholecystitis. The purpose of this study is to demonstrate that a delayed laparoscopic cholecystectomy in a real world scenario has no worse outcome in comparison with an early operation (within 72 hours after onset of symptoms).

Acute calculous cholecystitis (ACC) is the second most frequent surgical condition in emergency departments, the complication rate of ACC is 8-20%, and the mortality rate is 0.5-6% in recent series. The Tokyo Guidelines (TG) advocate for different risk factors and 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 complications in ACC. 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 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.

Acute calculous cholecystitis (ACC) is the most common complication of gallstone disease, and laparoscopic cholecystectomy is the gold standard treatment. Several prospective studies have demonstrated that same-admission, early LC (ELC), for ACC is safe when compared with delayed LC (DLC). However, there is still controversy on the indication of ELC in high risk patients with important comorbidities, in cases of severe inflammation of the gallbladder and in patients with ACC and suspicious of a choledocholithiasis. The advantages of ELC in high risk patients with severe comorbidities have been recently questioned, with Tokyo Guidelines 2018 (TG18) proposing an initial conservative management of this cases, assessing the benefit of ELC according to specified criteria. However, the recent CHOCOLATE trial, demonstrated the advantages of ELC over an initial conservative management. Performing an ELC for ACC can be a straightforward procedure for an on-call general surgeon or a very challenging procedure even for experienced hepatopancreaticobiliary (HPB) laparoscopic surgeon, depending on disease features, surgeons experience, centres volumes and resources available. Deciding whether the ELC should be performed by the on-call team or by HPB surgical team, or whether the operation should be delayed are still matter of debate in daily practice. Several preoperative scores assessing the risk of difficult cholecystectomy have been proposed, but they were mainly focused on elective procedures and on risk of conversion to open cholecystectomy or other intraoperative complications. They did not asses the risk of post-operative complications in a subgroup of patients, for whom, indication to ELC by the on-call general surgeon is still questionable according to the more recent guidelines.

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.

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.

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.

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.

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.
