BACKGROUND: Fluorescence cholangiography using indocyanine green (ICG) can enhance orientation of bile duct anatomy during laparoscopic cholecystectomy. To ensure clear discrimination between bile ducts and liver, the fluorescence ratio between both should be sufficient. This ratio is influenced by the ICG dose and timing of fluorescence imaging. We first systematically identified all strategies for fluorescence cholangiography. Second, we aimed to optimize the dose of ICG and dosing time in a prospective clinical trial...

The benefits of electrosurgery have been acknowledged since the early 1920s, and nowadays more than 80% of surgical procedures involve devices that apply energy to tissues. Despite its widespread use, it is currently unknown how the operator's choices with regard to instrument selection and application technique are related to complications. As such, the manner in which electrosurgery is applied can have a serious influence on the outcome of the procedure and the well-being of patients. The aim of this study is to investigate the variety of differences in usage of electrosurgical devices...

BACKGROUND: Situs inversus totalis is a rare autosomal disorder in which the patient's affected visceral organs are a perfect mirror image of their normal positions. Surgery in these patients is technically challenging. Minimally invasive surgery such as laparoscopic cholecystectomy is the standard treatment for symptomatic cholelithiasis, but it can be difficult to perform. Laparoscopic cholecystectomy in patients with situs inversus totalis may be even more technically challenging. Fluorescence cholangiography is a new innovation in the field of navigation surgery...

BACKGROUND: Laparoscopic cholecystectomy (LC) to treat mild biliary acute pancreatitis (MBAP) during index admission is recommended. However, the optimal surgical timing is controversial, considering that patients are actually often discharged from hospital and readmitted for elective cholecystectomy. Moreover, previous studies showed an uneven patients' stratification for pancreatitis severity. The aim of this study was to determine the outcome of patients homogenously categorised for MBAP according to the newest pancreatitis classifications, undergoing cholecystectomy with different timing...

BACKGROUND: Although early laparoscopic cholecystectomy is widely performed for acute cholecystitis, the optimal timing of a cholecystectomy in clinically ill patients remains controversial. This study aims to determine the best practice for the patients presenting with acute cholecystitis focused on disease severity and co-morbidities. PATIENTS AND METHODS: An international multicentric retrospective observational study was conducted over a 2-year period. Patients were divided into four groups, Group A: primary cholecystectomy, Group B: cholecystectomy after gallbladder drainage, Group C: gallbladder drainage alone, and Group D: medical treatment alone...

Surgical workflow recognition has numerous potential medical applications, such as the automatic indexing of surgical video databases and the optimization of real-time operating room scheduling, among others. As a result, surgical phase recognition has been studied in the context of several kinds of surgeries, such as cataract, neurological, and laparoscopic surgeries. In the literature, two types of features are typically used to perform this task: visual features and tool usage signals. However, the used visual features are mostly handcrafted...

The laparoscopic cholecystectomy (LC) is an important approach of treating acute cholecystitis and the timing of performing this given treatment is associated with clinical outcomes. Although several meta-analyses have been done to investigate the optimal timing of implementing this treatment, the conflicting findings from these meta-analyses still confuse decision-making. And thus, we performed this systematic review to assess discordant meta-analyses and generate conclusive findings to facilitate informed decision-making in clinical context eventually...

Acute cholecystitis is one of the most common surgical diagnoses encountered by general surgeons. Despite its high incidence there remains a range of treatment of approaches. Current practices in biliary surgery vary as to timing, intraoperative utilization of biliary imaging, and management of bile duct stones despite growing evidence in the literature defining best practice. Management of patients with acute cholecystitis with early laparoscopic cholecystectomy (LC) results in better patient outcomes when compared with delayed surgical management techniques including antibiotic therapy or percutaneous cholecystostomy...

INTRODUCTION: Definitive assessment of laparoscopic skill improvement after virtual reality simulator training is best obtained during an actual operation. However, this is impossible in medical students. Therefore, we developed an alternative assessment technique using an augmented reality simulator. METHODS: Nineteen medical students completed a 6-week training program using a virtual reality simulator (LapSim). The pretest and post-test were performed using an object-positioning module and cholecystectomy on an augmented reality simulator(ProMIS)...

Gallstones are a very common disease in our area, with a prevalence of 21.9%. Among the most common complications, choledocholithiasis is associated in about 3% to 10% of cases. The treatment may be performed by minimally invasive laparoscopy, endoscopy or a combination of both. There is no current consensus on what is the best strategy for treatment. We aimed to review the evidences of highest quality available, comparing two therapeutic strategies for cholelithiasis. Choledocholithiasis is divided into that in patients who underwent a cholecystectomy and that in patients with associated cholelithiasis...

PURPOSE: The rise of intraoperative information threatens to outpace our abilities to process it. Context-aware systems, filtering information to automatically adapt to the current needs of the surgeon, are necessary to fully profit from computerized surgery. To attain context awareness, representation of medical knowledge is crucial. However, most existing systems do not represent knowledge in a reusable way, hindering also reuse of data. Our purpose is therefore to make our computational models of medical knowledge sharable, extensible and interoperational with established knowledge representations in the form of the LapOntoSPM ontology...
