Active clinical trials for "Cholecystitis"

Transvaginal hybrid procedures especially the transvaginal hybrid cholecystectomy are of interest as an available NOTES-Procedure for the clinical routine. Few authors have demonstrated the feasibility and safety in a selected patient collective. The aim of this prospective data collection is to evaluate the feasibility in the clinical routine in a non select patient collective. Therefore all patients giving the informed consent to the transvaginal hybrid cholecystectomy will be included and assessed concerning feasibility to perform the transvaginal approach and complete the operation transvaginally.

The aim of this manuscript is to illustrate a new method permitting safe cholecystectomy in terms of complications with respect to the common bile duct (CBD). The core of this new technique is identification of the continuity of the cystic duct with the infundibulum. The cystic duct can be identified between the inner gallbladder wall and inflamed outer wall. In the last 2 years, 3 patients have been treated with the reported technique without complications. Among the various cholecystectomy procedures, this is a new approach that ensures the safety of the structures of Calot's triangle while providing the advantages gained from total removal of the gallbladder.

Rationale: Several clinical feasibility studies have shown the potential benefit of near-infrared fluorescence (NIRF) imaging using indocyanine green (ICG) for enhanced and earlier biliary anatomy visualization during laparoscopic cholecystectomy with the aim to reduce the number of vascular and biliary injuries. Although the incidence of injuries is low (0.7%), the impact on patients in terms of morbidity, quality of life and costs are dramatic. The Critical View of Safety (CVS) technique is regarded as the safety valve in conventional laparoscopic cholecystectomy (CLC). It is hypothesized that standard application of near-infrared fluorescence imaging during laparoscopic cholecystectomy can be useful to obtain establishment of CVS (at least 5 minutes) earlier and with more certainty regarding visualization when compared to conventional laparoscopic imaging alone. Study design: A multicenter randomized controlled trial with two study arms. Patients scheduled for an elective laparoscopic cholecystectomy will be recruited and randomized at the outpatient clinic (n = 308 total). One group will undergo near-infrared fluorescence cholangiography assisted laparoscopic cholecystectomy (NIRF-LC) and the other group will undergo conventional laparoscopic cholecystectomy (CLC). Compared with standard care, patients in the NIRF-LC group have to receive one preoperative intravenous injection of ICG. This is the only additional minimally invasive action for the patient. Initially, patients participating in this study will not benefit from the application of NIRFC during the surgical procedure. The administration of ICG and the modified laparoscope itself are not related with any kind of additional risk for the patient. Despite the encouraging results from several (pre)clinical feasibility studies, wide clinical acceptance of the routine use of ICG fluorescence laparoscopy is still lacking due to the absence of reliable and validated clinical data. A randomized clinical study is desirable to assess the potential added value of the NIRF imaging technique during laparoscopic cholecystectomy. Strong evidence in favor of routine implementation of this new imaging technique during laparoscopic cholecystectomy, will probably lead to worldwide routine application of the NIRF technique. Therewith long term sustainability of this research project is guaranteed.

The aim of this study is to compare early postoperative outcomes of unselected consecutive patients underwent laparoscopic cholecystectomy (LC) under spinal versus general anesthesia.

This VA QUERI Partnered Evaluation Initiative will evaluate the impact of an immersive Point-of-care Ultrasound (POCUS) Training Course on provider skill acquisition and retention; the frequency of POCUS use by trained providers; and the barriers/facilitators to POCUS in the VHA. Data sources include pre- and post-course assessment tools, medical coding data, and course evaluations. Providers that participate in the POCUS Training Course will be compared to control providers from wait-listed facilities. Additionally, participating facilities vs. wait-listed facilities for the POCUS Training Course will be compared. Findings from this project will guide ongoing efforts of the investigators' operating partners, VA Specialty Care Centers of Innovation (SCCI) and the VA Simulation Learning and Research Network (SimLEARN), to develop a national POCUS training program and facilitate implementation of POCUS use system-wide in the VA healthcare system.

A semi-rigid cervical collar is recommended for immobilization of the cervical spine in patients with cervical spine injury. It has been suggested that a reduction in mouth opening is the major contributing factor to the deterioration in the glottic view obtained. Fiberoptic intubation is among the most versatile techniques for managing both the anticipated and the unanticipated difficult airway. Recently, combination of fiberoptic bronchoscope with videolaryngoscope has been suggested to permit visual control of the passage of the tube over the fibrescope into the laryngeal inlet. The aim of this study is to compare the intubation time and ease of intubation between fiberoptic bronchoscope alone and bronchoscope with pentax airwayscope.

Patients diagnosed with acute cholecystitis benefit from emergency laparoscopic cholecystectomy (LC). Patients who had emergency LC showed improvement in quality of life in one month compared to those treated. Delayed LC (after the acute cholecystitis has passed) and less time to recover from work. This strategy reduces the risk of repeated referrals with more pain or pancreatitis. There are many studies on the efficacy of intraoperative intraperitoneal bupivacaine(IPBV) with elective LC on pain of IPBV. However, the prospective study of reducing the postoperative pain of emergency LC - IPBV is very few. This study will be conducted to evaluate the efficacy of IPBV in patients with emergency LC.

This is a prospective observational cohort study to assess the utility of bio-degradable bile duct stent in the drainage of bile duct. All consecutive patients who will undergo ERCP procedure for bile leaks and patients with bile duct stones and intact gall bladder will be recruited to the study. The planned sample size is 53 and patients will be followed up for 180 days. The primary objective is to assess the utility of biodegradable bile duct plastic stents in the drainage of bile duct. The secondary Secondary objectives are To assess Technical success of biodegradable stents Complications Patient related cost savings (Time off work, travel time for the patient) Hospital related cost savings (Repeat procedure costs, follow up appointments)

With the progressive aging of the population in industrialized countries, acute calculous cholecystitis (ACC) has been constantly increasing among elderly. Because ACC is the most common complication of biliary gallstone disease and the population will become older, ACC in elderly is expected to increase. In 2017, the incidence of gallstone disease in Italian population is was 18.8% in women and 9.5% in men; the prevalence was 15% and 24% at 70 years and 24% and 35% at 90 years for males and females respectively. Since the increase in age is often associated with an increase in comorbidity, fragility, surgery related complications, morbidity and mortality, the surgical indication for gallstone is still debated and often based on anesthetic risk. In order to avoid surgery for elderly and high-risk patients, alternative treatments to surgery have been developed. The present study aimed to compare two groups of patients with acute calculous cholecystitis undergone laparoscopic cholecystectomy, under and over 70 years old and to assess whether laparoscopy can offer the same safety and efficacy to older people.

This study looks at the differences in inflammatory mediators in gallbladder tissue between males and females and the possibility that these differences contribute to a higher perception of post-operative pain in females following laparoscopic cholecystectomy.
