Cholecystolithiasis

This study aims to understand public/patient attitudes toward gallbladder preservation surgery by means of questionnaires, and hopes to achieve the following objectives: 1. To understand public/patient attitudes towards gallbladder preservation surgery and provide new evidence for the controversy over gallbladder preservation surgery; 2. Introduce a new kind of "evidence" into this controversy: social or preference evidence； 3. Verify the applicability of informed choice and shared decision making； 4. Provide "public opinion" reference for medical policy and guideline formulation ，and help them develop guidelines or policies that are more in line with patients 'needs； 5. Help clinicians understand patients 'concerns, provide basis for making more scientific individualized treatment decisions, and promote the standardization process of diagnosis and treatment of benign gallbladder diseases. The survey will be conducted in the Second People's Hospital of Changzhou City from July 2026 to December 2026 in the form of questionnaire (electronic questionnaire). The questionnaire will be distributed to all regions of the Chinese mainland, and will be conducted daily by in-hospital doctors and designated questionnaire collectors.

Common bile duct stones (CBDS) may be asymptomatic but can cause pancreatitis, obstructive jaundice, and/or cholangitis. In Sweden, intraoperative cholangiography (IOC) is usually performed during gallstone surgery in order to detect CBDS and proactively extract them. The intervention to extract them may, however, cause complications by itself such as pancreatitis, bleeding, or perforation. In many countries, IOC is performed selectively when CBDS are suspected preoperatively (by patient history, imaging, or blood tests), or if the anatomy is unclear. There is a knowledge gap regarding the relation between risks associated with refraining from IOC and, thus, leaving undetected CBDS in situ, or actively diagnosing and removing the stones. To compare these risks, we propose a national multicenter randomized controlled trial. The study will be embedded in the Swedish Registry for Gallstone Surgery (GallRiks), which will include all variables for inclusion and follow-up. Population: Patients undergoing gallstone surgery without suspicion of CBDS Intervention: IOC Control: No IOC Outcome: Readmission or reintervention (Clavien-Dindo grade ≥IIIa) related to the cholecystectomy within 12 months after the operation. A total of 6000 patients will be recruited. The results will have the potential to provide level A evidence for routines used in gallstone surgery not only in Sweden, but also internationally.

Endotracheal tube (ETT) is the gold standard conduit for providing controlled ventilation during general anaesthesia (GA). however, the supra-glottic airway (SGA) devices in particular the laryngeal mask airway (LMA) and its variants have become a reliable alternative to ETT for carrying out controlled ventilation. Of the several variants of LMA available today, the proseal LMA (PLMA) is preferred for controlled ventilation. The various advantages of LMA includes, a lower incidence of postoperative sore throat and superior haemodynamic profile during surgery. However, one aspect of providing anaesthesia with LMA compared to ETT is the ability of LMA to maintain equivalent depth of anaesthesia with lower anaesthetic requirement, is quiet intriguing and evidence to this regard is very limited. By measuring the anaesthesia requirement using a robust computerised delivery system such as the closed loop anaesthesia delivery system (CLADS) we can establish for sure the anaesthesia required for maintaining intraoperative mechanical ventilation with the use of these two (ETT and PLMA) airway management devices. This randomised controlled study aims to calculate the anaesthesia requirement as determined by the total amount of propofol consumed for maintaining anaesthesia with ETT versus PLMA

This prospective clinical cohort study will include patients with gallstones and abdominal pain scheduled for surgery (laparoscopic cholecystectomy). Data on quality of life, abdominal pain, gallstone disease, and patient characteristics will be collected before surgery. The outcomes will be assessed three months following surgery and will primarily be determinants for resolution of pain. The aim is to make a prediction score that may aid clinicians and patients in decision making about surgery.
