Eligibility Criteria
Inclusion
- Preoperative
- Subject is ≥22 years at the time of consent.
- Subject has a BMI ≤ 50 kg/m2.
- Subject has an ASA score of ≤ 3.
- Subject has benign lesion(s) of the rectum or sigmoid colon, such as adenoma (with low- or high-grade dysplasia), neuroendocrine tumor, or other type of polyp as assessed by the most recent colonoscopy/flexible sigmoidoscopy.
- Subject has lesion ≤ 7 cm in size (dimension of greatest extent) and ≤ 75% of the colorectal circumference as assessed by the most recent colonoscopy/flexible sigmoidoscopy.
- Subject is eligible for standard endoscopic submucosal dissection.
- Subject agrees to participate in the study by giving signed informed consent.
- Preoperative
Exclusion
- Subject anatomy is unsuitable for endoscopic visualization or endoluminal surgery.
- Subject has a history of inflammatory bowel disease.
- Subject has an untreated active infection at the time of the procedure.
- Subject is considered part of a vulnerable population (e.g., prisoners, mentally disabled).
- Subject has a severe concomitant illness that drastically shortens life expectancy or increases risk of therapeutic interventions (e.g., cancer).
- Subject is breastfeeding or pregnant or intends to become pregnant during the study.
- Subject is currently enrolled in or discontinued within the last 30 days from a clinical trial of an investigational drug or device, or concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study.
- Subject with EF ≤ 45, high cardiac or high pulmonary risk (these subjects require clearance from a cardiologist and pulmonologist, as applicable).
- Subject on preoperative blood thinners, such as coumadin or heparin, that cannot be weaned prior to surgery.
- Subject is moderately or severely immunocompromised.
- In the opinion of the Investigator, the subject is unable to comply with the requirements of the study protocol or is unsuitable for the study for any reason.
- Intraoperative Exclusion Criteria (assessed with third-party endoscope):
- Inadequate bowel prep.
- Complex anatomical findings not feasible for an endoluminal approach.
- Anatomical narrowing distal to the lesion site.
- Lesion not located in the rectum or sigmoid colon.
- Lesion size \>7 cm (dimension of greatest extent) or occupies \>75% of the colorectal circumference.
- Lesion demonstrates characteristics indicative of invasive carcinoma, such as failure to lift upon submucosal injection, or any other features that raise the Investigator's suspicion of cancer.
- Intraoperative Exclusion Criteria (assessed with study device):
- In the opinion of the Investigator, the subject and/or subject anatomy is not suitable for study device use for any reason.
- Lesion location not accessible by the study device.
