Cutaneous Sensory Block Area of the Laparoscopic Assisted Transversus Abdominis Plane Block
CholecystolithiasisThe goal of this observational study is to assess the size and location of cutaneous sensory block area after dual laparoscopic assisted transverse abdominis plane block (L-TAP) with ropivacaine in patients undergoing laparoscopic cholecystectomy. L-TAP is applied as a medial subcostal infiltration between midclavicular and central sternal lines and a lateral subcostal infiltration between midclavicular and anterior axillary line bilaterally.
Study on the Learning Curve for Fundus First With Ultrasonic Tissue Coagulation in Elective Cholecystectomy...
CholecystolithiasisThe present study aims at analyzing the learning curve for fundus first with the ultrasonic tissue coagulation dissection technique in elective cholecystectomy. Patients included in the study are planned for an elective cholecystectomy, on the basis of the gallstone disease. All participating surgeons have experience of the traditional approach with electrocautery. The operation time as well as the surgeons own evaluation of difficulty and performance are noted. Selected films are analyzed by independent surgeons with experience of the fundus first technique. The Swedish registry of gallstone surgery and ERCP (GallRiks) are used to record the intra and postoperative complication rate.
Indications for Gallbladder Surgery in Gallstone Disease
GallstonesThe aim of the study is to identify patients with gallstone disease that should be operated and those that may potentially be observed. This selection was based on symptoms and clinical presentation. The consequences that may arise for the patient if observation is chosen compared with outcome after cholecystectomy has been markers of outcome.
Closed-Loop Target Controlled Infusion in Laparoscopic Cholecystectomy
CholecystolithiasisLaparoscopic Cholecystectomy applied to Artificial pneumoperitoneum and the extent of Surgical stimulation cause the wave of hemodynamics increase vigorously, which make it difficult to judge the depth of anesthesia according to traditional hemodynamics index such as heart rate and blood pressure.In case of this, the investigators design this research to study the Closed-Loop Target Controlled Infusion to anaesthesia of individualization guided by a Narcotrend index monitor in Laparoscopic Cholecystectomy.
Microbiomes in Patients of Recurrent Common Bile Duct Stones
CholelithiasisCholedocholithiasisBile duct stones is a common biliary tract disease, which is characterized by high morbidity and frequent recurrence. Endoscopic retrograde cholangiopancreatography (ERCP) is an effective therapy for common bile duct stones, and endoscopic sphincterotomy (EST) which associated with recurrent cholangiolithiasis often carried out on difficult intubation or extracting stones, probably due to enhanced reflux of intestinal contents that changes the microenvironment. Patients with cholangiolithiasis were consecutively recruited and their bile was collected intra-operatively for high-throughput experiments. Pyrosequencing of 16S ribosomal RNA gene was performed to characterize the microbiota in the bile and other body fluids. A liquid chromatography mass spectrometry-based method was used to profile bile composition. Clinical manifestation, microbiome, and bile composition were compared between patients with or without recurrent of bile duct stones. The aim of our study was to identify the impact of microbiomes on the recurrent of bile duct stones after ERCP+EST therapy.

Acute PancreatitisAcute Pancreatic Necrosis8 moreAcute pancreatitis (AP) is an inflammatory disease of the pancreas, most commonly caused by gallstones, or excessive use of alcohol. It represents a management challenge and a significant healthcare burden. The incidence of AP ranges globally from 5 to 30 cases per 100.000 inhabitants/year, and there is evidence that the incidence has been rising in recent years. The overall case-fatality rate for AP is roughly 5%, and it is expectedly higher for more severe stages of the disease. In most cases (80%), the outcome of AP is rapidly favorable. However, acute necrotizing pancreatitis (ANP) may develop in up to 20% of cases, and is associated with significant rates of early organ failure (38%), needing some type of surgical/endoscopic intervention (38%) and death (15%). In the United States, AP is a leading cause of inpatient care among gastrointestinal conditions: more than 270.000 patients are hospitalized for AP annually, at an aggregate cost of over 2.5 billion dollars per year. In Europe, the UK incidence of AP is estimated as 15-42 cases per 100.000/year and is rising by 2.7% each year. Despite existing evidence-based practice guidelines for the management of biliary AP, clinical compliance with recommendations is poor, with studies on this field identifying major discrepancies between evidence-based recommendations and daily clinical practice. Audits about biliary AP have been performed in Italy, Germany, France, and England, with quite disappointing results. Indeed, in these audits, the treatment of biliary AP differed substantially from the recommendations. For example, less than 15% of the responders stated that they strictly followed all recommendations included in the guidelines in Germany and 25.8% of patients did not receive definitive treatment for biliary AP within 1 year in the UK. These findings support the view that publication alone of nationally or internationally developed and approved guidelines is insufficient to modify the practice of non-specialists and raises the question of how best to spread guideline recommendations. In 2020, the spread of the virus Covid-19 has represented a pandemic that also had a profound impact on the surgical community. There are many ways through which the outbreak of the Covid-19 pandemic could have influenced daily clinical practice for patients with biliary AP also leading to a failure to adhere to the recommendations coming from the guidelines, especially those regarding the early and definitive treatment with cholecystectomy or ERCP and sphincterotomy. First of all, the recommendation to postpone all non-urgent endoscopic procedures during the peak of the pandemic. Second, the recommendation to conservatively treat inflammatory conditions such as acute cholecystitis and acute appendicitis wherever possible. Since the clinical compliance with recommendations about AP is poor and the impact of implementing guideline recommendations in biliary AP has not been well studied on a global basis, we launched the MANCTRA-1 study with the aim to demonstrate areas where there is currently a sub-optimal implementation of contemporary guidelines on biliary AP. Moreover, we argue that during the Covid-19 pandemic the tendency to disregard the guidelines recommendations has been more marked than usual and we will try to find out if AP patients' care during the Covid-19 pandemic resulted in a higher rate of adverse outcomes compared to non-pandemic times due to the lack in the compliance of the guidelines. The MANCTRA-1 can identify a number of areas for quality improvement that will require new implementation strategies. Our aim is to summarize the main areas of sub-optimal care to provide the basis for introducing a number of bundles in the management of AP patients to be implemented during the next years. The primary objective of the study is to evaluate which items of the current AP guidelines if disregarded, correlate with negative clinical outcomes according to the different clinical presentations of the disease. Secondary objectives are to assess the compliance of surgeons worldwide to the most up-to-date international guidelines on biliary AP, to evaluate the medical and surgical practice in the management of biliary AP during the non-pandemic (2019) and pandemic Covid-19 periods (2020), and to investigate outcomes of patients with biliary AP treatment during the two study periods.
Efficacy of Choleretics in Acalculous Gallbladder in Situ After Endoscopic Removal of Biliary Stones...
Common Bile Duct StonesGallbladder in Situ2 moreIn patients with gallbladder in situ after complete removal of common bile duct (CBD) stones, there is no definite guideline for the management of remnant acalculous gallbladder. This study was planned to evaluate the efficacy of choleretic agents in those patients comparing with non-treatment group during short (2 years) and long-term (5 to 10 years) period. So that, the investigators want to establish the treatment guideline in gallbladder in situ without definite stones following complete removal of CBD stones. Second, the protective or preventive effect of choleretics may be defined.
Chinese Registry Study on Treatment of Cholecysto-Choledocholithiasis
GallstonesCholelithiasis2 morePatients with gallstone and confirmed common bile duct stones are registered in this study. The three managements for common bile duct stones are endoscopic sphincterotomy (EST), laparoscopic common bile duct exploration (LCBDE) and laparoscopic transcystic common bile duct exploration (LTCBDE). Patients will be assessed at baseline, preoperative investigations, operative method, operative time, conversion to open procedure, intraoperative and postoperative complications, and the presence of retained and recurrent stones. All patients were followed up for 3 years by telephone interview ang outpatient visits. Abdominal US and liver function tests were carried out whenever any abdominal symptom appeared during the follow-up period. If there were unusual findings, magnetic resonance cholangiopancreatography(MRCP) was carried out.
