Natural Orifice Specimen Extraction in Low Rectal Cancer Surgery (NOSES)

June 25, 2024 updated by: Istituto Clinico Humanitas

Postoperative Outcomes of Natural Orifice Specimen Extraction (NOSE) in Low Rectal Cancer Surgery

This study aims to compare the postoperative outcomes of low rectal cancer patients who underwent surgery with Natural Orifice Specimen Extraction (NOSE) versus traditional Pfannenstiel extraction.

Study Overview

Status

Status

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

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

Natural Orifice Specimen Extraction (NOSE) in colorectal surgery allows the extraction of the surgical specimen through the anal orifice. Several studies demonstrated improved postoperative pain, bowel movements, patient-reported cosmetic satisfaction, and psychological wellbeing after NOSE compared with traditional Pfannenstiel extraction. However, most of these studies focused on colon surgery. The aim of this retrospective propensity score matched study is to investigate the postoperative outcomes of NOSE in low rectal cancer surgery, classified according to the English National Low Rectal Cancer Development Programme (LOREC).

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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

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
Surgical Site Infections (SSI)
Time Frame: 30 days after surgery
Rate difference of 30-day Surgical Site Infections (SSI)- defined according to the definition of the Center for Disease Control and Prevention (CDC) [Ref]- between the study cohorts.
30 days after surgery

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
Opioid rescue
Time Frame: From the date of surgery to the date of discharge
Difference in the proportion of patients requiring opioid rescue during the hospitalization
From the date of surgery to the date of discharge
Postoperative pain
Time Frame: 72 hours after surgery
The median difference of 72-hour patient-reported pain- measured on the Visual Rating Scale (VRS)
72 hours after surgery
Postoperative ileus
Time Frame: 30 days after surgery
Rate difference of 30-day postoperative functional ileus (define as the absence of bowel function for at least three days)
30 days after surgery
Incisional hernia
Time Frame: 6 months after surgery
The rate difference of six-month incisional hernia
6 months after surgery
Overall postoperative complications
Time Frame: 30 days after surgery
The rate difference of overall 30-day postoperative complications, classified according to the Clavien-Dindo scale [ranging from 0 (no complications) to 5 (complications leading to death)]
30 days after surgery

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
