The Comparison of Single Incision Laparoscopic Appendectomy and Three Port Laparoscopic Appendectomy

March 21, 2013 updated by: manuk norayk manukyan, Maltepe University
Laparoscopic techniques have allowed surgeons to perform complicated intrabdominal surgery with minimal trauma. In numerous studies, when conventional laparoscopic appendectomy using 3 ports is compared with open appendectomy, it has advantages of reduced pain, reduced hospital stay, and enhanced cosmetic effects. Single incision laparoscopic surgery (SILS) was developed with the aim of reducing the invasiveness of conventional laparoscopy. In this study the investigators aimed to compare results of SILS appendectomy and three port conventional laparoscopic appendectomy prospectively.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Total of 50 patients who undergoing laparoscopic appendectomy for acute appendicitis will randomly assign to undergo SILS appendectomy group (n = 25) or Three port laparoscopic appendectomy group (n= 25) according to a computer-generated table of random numbers. Demographics (ie, age, gender, body mass index (BMI), American Society of Anesthesiology (ASA) score, need for conversion to a standard or three port laparoscopic appendectomy, need for conversion to an open appendectomy will be recorded. Outcome measures include operative morbidity, operative time, pain score, hospital stay. Morbidity will be evaluated by rates of colonic leak, wound infection, intrabdominal abscess hospital readmission, and hernia.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
Pain score
Time Frame: Postoperative first 24 hours
Postoperative pain will be assessed according Visual analog scale from 0 (no pain) to 10 (worst pain imaginable. Postoperative six hour VAS (POSH-VAS) and postoperative first day VAS (POFD-VAS) will be recorded and compared.
Postoperative first 24 hours

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
Intraoperative complications
Time Frame: Average of 50 minutes

Per operative complications will be recorded.

  • Bleeding
  • Iatrogenic injury
  • Bowel perforation
  • Complications associated with increased intra-abdominal pressure
Average of 50 minutes
Operating time
Time Frame: Average of 50 minutes
The operating time will be defined as the time from the first incision to the last suture's placement.
Average of 50 minutes

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.
