Interrater Agreement of Height Assessment by Rigid Proctoscopy/Rectoscopy for Rectal Carcinoma.
Dis Colon Rectum
August 2024
Department of Neurosurgery, Haukeland University Hospital, Bergen, Norway.
Background: Some guidelines for rectal carcinoma consider 12 cm, measured by rigid endoscopy, to be the cutoff tumor height for optional neoadjuvant chemoradiation therapy. Measuring differences of only a few centimeters may predetermine the choice of further therapy. However, rigid endoscopy may exhibit similar operator dependence to most other clinical examination methods.

Article Synopsis
- Rectocutaneous fistulae develop from infections in anal glands and can lead to perineal masses, as seen in a rare case of cellular angiofibroma (CAF) associated with such a fistula.
- A 52-year-old male with a 2-year history of a painful perineal mass underwent imaging that revealed its connection to a rectocutaneous fistula, leading to surgical excision and diagnosis of CAF.
- The case illustrates that CT imaging is effective for diagnosing perineal lesions, and CAFs can be successfully removed even when linked to cutaneous fistulas.
High-resolution rectoscopy using MHz optical coherence tomography: a step towards real time 3D endoscopy.

Interdisciplinary Endoscopy, Medical Department 1, University Hospital Schleswig-Holstein, Campus Kiel, Kiel, Germany.
Colonoscopy and endoscopic ultrasound play pivotal roles in the assessment of rectal diseases, especially rectal cancer and inflammatory bowel diseases. Optical coherence tomography (OCT) offers a superior depth resolution, which is a critical factor for individualizing the therapeutic concept and evaluating the therapy response. We developed two distinct rectoscope prototypes, which were integrated into a 1300 nm MHz-OCT system constructed at our facility.

Consultant Colorectal Surgeon, Imperial College Healthcare NHS Trust, London, UK
Background: Access to community rectoscopy might help to ease the burden on hospital services and reduce costs for the NHS. To assess this, a prospective multicentre observational phase I feasibility study of a novel digital rectoscope and telestration software for the triage of lower gastrointestinal (GI) symptoms was undertaken.
Aim: To determine if digital rectoscopy is feasible, acceptable, and clinically safe.
An evaluation of trans-anal rectoscopic-assisted minimally invasive surgery (ARAMIS): a new platform for transanal surgery.
Int J Colorectal Dis
September 2020
Department of Surgery, Oncology and Gastroenterology, Section of Surgery, University of Padova, Clinica Chirurgica 3^, Sesto Piano Policlinico, Via Giustiniani 2, 35128, Padova, Italy.
Purpose: The study aimed to evaluate the feasibility and safety of a new trans-anal rectoscopic-assisted minimally invasive surgery (ARAMIS) platform to treat rectal lesions.
Methods: ARAMIS was first compared with two transanal minimally invasive surgery platforms (SILS Port and GelPOINT Path) on human cadavers. Surgeons with different experience performed running sutures at different distances, at four quadrants, using the three platforms and gave a score to visibility, safety, and maneuverability.
