Clinical Study of Single Incision Laparoscopic Cholecystectomy in the Treatment of Patients With Acute Cholecystitis

November 18, 2024 updated by: Second Affiliated Hospital, School of Medicine, Zhejiang University
Gallstone is a common disease in China.At present, the prevalence of gallstones in China is 15 %, and about 210 million people are sick. Acute cholecystitis is acute gallbladder inflammation, is one of the main complications of cholelithiasis or gallstones. The removal of gallbladder and gallstones in patients with acute cholecystitis in the presence of biliary pain will prevent the recurrence of gallbladder and reduce the risk of cholecystitis progression. If gallbladder perforation is not treated in time, the mortality rate is 30 %. Acute acalculous cholecystitis without treatment will be life-threatening, with a mortality rate of up to 50 %. At present, the vast majority of patients with acute cholecystitis are treated with 4-hole traditional laparoscopic cholecystectomy and open cholecystectomy. Their postoperative quality of life, pain and scar-related complications, remain major factors for patients.In recent years, with the renewal of the concept of minimally invasive surgery and the continuous advancement of instruments and technology, single-incision laparoscopic cholecystectomy has also maximized the quality of life after surgery and reduced postoperative pain and scar-related complications. At present, there are few reports on randomized controlled clinical trials of SILC in patients with acute cholecystitis, and there is a lack of large sample size studies.Due to the difficulty of SILC operation, the longer learning curve, the different equipment conditions and technical characteristics of each center, and the lack of standardized training, there is no effective consensus on the application indications and operation procedures of SILC in acute cholecystitis surgery. Based on the current status, the purpose of this study was to investigate the effect of SILC on postoperative quality of life, postoperative pain, scar assessment and postoperative complications in patients with acute cholecystitis, so as to propose a standardized single incision laparoscopic operation procedure in the treatment of acute cholecystitis.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Quality of life (time to return to normal life)
Time Frame: 3 years
The quality of life of patients after operation was investigated by a unified SF-36 questionnaire. The higher the final score, the better the quality of life.
3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cosmetic result
Time Frame: 3 years
Evaluation of postoperative incisional scarring using the Vancouver Scar Scale. The lower the score, the higher the scar satisfaction.
3 years

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
