Laparoscopic Appendectomy by Multi-port vs Single Port. (AMUSING)

November 2, 2012 updated by: Nereo Vettoretto, Associazione Chirurghi Ospedalieri Italiani

Randomized Controlled Trial Comparing Single Incision Laparoscopic Appendectomy Versus Standard Three Port Appendectomy in a Selected Cohort of Patients

Laparoscopic appendectomy (LA) is nowadays considered the gold standard in fertile women affected by uncomplicated appendicitis. The level of evidence for benefits from LA in this subgroup is high. Since the dissemination of single access surgery (no-scars surgery) ameliorated outcome has been supposed in these patients regarding post-operative pain, hospital stay and cosmetics results, and keeping the same safety as LA. This randomized controlled study is supposed to give answers to these questions.

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.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Single incision laparoscopic appendectomy
Acute appendicitis with surgical indication
Procedure: Single incision laparoscopic appendectomy
A multiport device will be introducted through a 2-2.5 transumbilical incision. Retraction of the appendix would be performed with a forceps. The mesoappendix will be divided with bipolar or monopolar cautery. The appendix stump will be ligated with suture loop or with an endo-stapler. The specimen will be delivered within a plastic bag or in any protected way (without any contact with the abdominal wall) via the umbilical port. Any fluid will be suctioned and washing performed if required. Fascial defects will be closed with 2-O polydioxanone sutures and skin closed with 4-O non-absorbable sutures. No pelvic drain will be inserted. A three-band dressing will be applied in the end.

  • SILA
Active Comparator: Multiport Laparoscopic appendectomy
Acute appendicitis with surgical indication
Procedure: Multiport laparoscopic appendectomy
Three ports will be inserted as follows: One 10/12 umbilical port, one 5mm suprapubic (or right suprapubic)port, one 5mm or 10/12mm port in left iliac fossa (or left suprapubic). One additional trocar can be inserted following surgeons preference. Retraction of the appendix would be performed with a forceps. The mesoappendix will be divided with bipolar or monopolar cautery. The appendix stump will be ligated with suture loop or with an endo-stapler. The specimen will be delivered within a plastic bag or in any protected way (without any contact with the abdominal wall) via the umbilical port. Any fluid will be suctioned and washing performed if required. Fascial defects (10/12 trocars)will be closed with 2-O polydioxanone sutures and skin closed with 4-O non-absorbable sutures. No pelvic drain will be inserted. A three-band dressing will be applied in the end.

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.

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.
