Validation of a Tool-Based Visual Anorectal Examination Advanced Simulator for the Early Detection of Colorectal Cancer.

Rectal examination through proctoscopy or rigid sigmoidoscopy is a common investigation in clinical practice. It is an important diagnostic tool for the workup and management of anorectal pathologies. Performing the examination can be daunting not only for patients but also for junior doctors.

An Unusual, Delayed Presentation of a Migrated Intrauterine Contraceptive Device Into the Rectosigmoid Colon.

The current literature suggests that serious complications after intrauterine contraceptive device (IUCD) insertion are rare. We present a rare case of a migrated IUCD into the rectosigmoid colon. A 33-year-old woman (parity one) presented to the emergency department with a three-day history of flank pain, upper urinary tract infection symptoms, and a low-grade fever.

Robotic-assisted Laparoscopic Repair of a Penetrating Extraperitoneal Bladder Injury.

Background: Traumatic intraperitoneal or complicated extraperitoneal bladder injuries are conventionally managed with open exploration and repair. There are rare reports in the literature of laparoscopic repair of intraperitoneal bladder injury secondary to blunt abdominal trauma, as well as two reports of laparoscopic repair of extraperitoneal bladder injuries from blunt abdominal trauma. There are no reported cases of a minimally invasive surgical repair of a penetrating bladder injury.

Splenic Capsule Injury: A Rare Complication of Sigmoid Volvulus.

Sigmoid volvulus can lead to life-threatening complications. We report a splenic capsule avulsion injury requiring laparotomy as a complication of sigmoid volvulus. A 73-year-old woman was admitted with abdominal distension, rigidity, and tenderness.

Intraoperative Anastomotic Evaluation Methods: Rigid Proctoscopy Versus Flexible Endoscopy.

Introduction: Rigid proctosigmoidoscopy (RP) and flexible sigmoidoscopy (FS) are two modalities commonly used for intraoperative evaluation of colorectal anastomoses. This study seeks to determine whether there is an association between the endoscopic modality used to evaluate colorectal anastomoses and the rate of anastomotic leak (AL), organ space infection, and overall infectious complication.

Methods: The 2012-2018 American College of Surgeons National Surgical Quality Improvement Program database was queried for patients undergoing colorectal anastomoses.

Assessment of the efficacy of Handmade Vacuum-Assisted Sponge Drain for Treatment of Anastomotic leakage after Low Anterior Rectal Resection.

Anastomotic leakage is one of the major complications of colorectal surgery, which might lead to reoperation, increased hospital stays, further intervention and mortality. Vacuum-assisted closure by devices such as Endo-SPONGE® produced by (B-Braun Medical B.V.

Health-related quality of life in patients with long-standing ulcerative colitis in remission.

Introduction: Ulcerative colitis (UC) contributes to impaired health-related quality of life (HRQoL). Although disease activity is the most important factor, reduced HRQoL has been reported even in quiescent UC. We aimed to determine HRQoL, and identify predictors thereof, in patients with long-standing UC in remission.

Delayed traumatic rupture of ovarian endometrioma on re-exploration after blunt abdominal trauma.

Traumatic rupture of an ovarian endometrioma is extremely rare injury. We describe a case of a 63-year-old female presenting after a motor vehicle crash (MVC) with complex abdominal injuries requiring exploratory laparotomy that was complicated by delayed presentation of an ovarian endometrioma rupture on second look laparotomy. During the repeat exploration of the abdomen, multiple regions of small bowel and the pelvic floor were noted to be covered with a brown-colored material which was concerning for fecal matter from a missed enterotomy.

Linitis plastica of the rectum secondary to metastatic prostate cancer: A case report of a rare presentation and literature review.

Linitis plastica is a rare tumor with poor prognosis. It is a circumferentially infiltrating intramural tumor which can result in rigid, nondistensible thickening of the affected organ. It most commonly affects the stomach, followed by the rectum, and can be due to primary or secondary cancer.

An Observational Analysis of a Novel Digital Rectoscope.

Background: This is an analysis of the first 50 in-human uses of a novel digital rigid sigmoidoscope. The technology provides digital image capture, telemedicine capabilities, improved ergonomics, and the ability to biopsy under pneumorectum while maintaining the low cost of conventional rigid sigmoidoscopy. The primary outcome was adverse events, and the secondary outcome was diagnostic view.

Penetrating gluteal injuries in North West London: a retrospective cohort study and initial management guideline.

Background: Penetrating gluteal injuries (PGIs) are an increasingly common presentation to major trauma centers (MTCs) in the UK and especially in London. PGIs can be associated with mortality and significant morbidity. There is a paucity of consistent guidance on how best to investigate and manage these patients.

Organ Preservation in the Treatment of Stage II and III Rectal Cancer.

A 65-year-old man underwent colonoscopy to evaluate rectal bleeding and was found to have a low rectal mass. Biopsy revealed moderately differentiated microsatellite stable adenocarcinoma. The tumor was palpable at the fingertip in the anterior rectum with the inferior border 5 cm from the anal verge by rigid proctoscopy.

Treatment Strategies for Massive Presacral Bleeding.

An 84-year-old male patient was complaining of constipation and rectal bleeding for 6 months. Colonoscopy and rigid sigmoidoscopy showed a posterior upper rectal mass (13 cm from anus). Histopathology confirmed moderately differentiated adenocarcinoma.

How to accurately measure the distance from the anal verge to rectal cancer on MRI: a prospective study using anal verge markers.

Purpose: To determine an accurate method for localizing rectal cancer using the distance from the anal verge on preoperative MRI.

Methods: This prospective study included 50 patients scheduled for MRI evaluation of rectal cancer. After rectal filling with gel, MRI was performed with two markers attached at the anal verge.

Contemporary management of rectal trauma - A South African experience.

Introduction: The management of rectal trauma remains controversial. There are three modalities which have been used to manage these injuries; proximal diversion (PD), washout of the distal rectum (DRW) and presacral drainage (PSD). The EAST group tentatively advocate mandatory proximal diversion for extraperitoneal rectal injuries and omitting DRW or PSD.

Management of acute sigmoid volvulus in a provincial centre-a 20-year experience.

Aim: At our institution there has been a long-standing early operative approach to large bowel volvulus as well as initial decompression with rigid sigmoidoscopy. The primary aim of this study was to investigate the safety and efficacy of this approach on reducing readmissions and complications. Secondary aims were to investigate the safety and efficacy of bedside rigid sigmoidoscopy in decompression of sigmoid volvulus and investigate the sensitivity of abdominal x-ray in the diagnosis of acute large bowel volvulus.

Computed tomography and magnetic resonance imaging findings of metastatic rectal linitis plastica from prostate cancer: A case report and review of literature.

Linitis plastica is a rare condition showing circumferentially infiltrating intramural anaplastic carcinoma in a hollow viscus, resulting in a tissue thickening of the involved organ as constricted, inelastic, and rigid. While most secondary rectal linitis plastica (RLP) is caused by metastasis from stomach, breast, gallbladder, or bladder cancer, we report an extremely rare and unique case of secondary RLP due to prostate cancer with computed tomography (CT) and magnetic resonance imaging (MRI) findings, including diffusion weighted imaging (DWI). A 78-year-old man presented with approximately a 2-mo history of constipation and without cancer history.

Repeated rectal application of a hyperosmolar lubricant is associated with microbiota shifts but does not affect PrEP drug concentrations: results from a randomized trial in men who have sex with men.

Introduction: Oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) is highly effective in preventing HIV infection among men who have sex with men (MSM). The effects of consistent personal lubricant use in the rectum on tissue PrEP drug concentrations and the rectal microbiota are unknown. We investigated rectal PrEP drug concentrations and the microbiota in MSM before and after repeated rectal application of a hyperosmolar lubricant.

Accuracy of pelvic MRI in measuring tumor height in rectal cancer patients with or without preoperative chemoradiotherapy.

Introduction: In measuring tumor height for rectal cancer, rigid sigmoidoscopy (RS) is a standard modality, and the accuracy of magnetic resonance imaging(MRI) in patients with/without preoperative chemoradiotherapy (CRT) has not been fully investigated. The aim of this study was to investigate the accuracy of MRI for measuring tumor height.

Materials And Methods: Among rectal cancer patients seen between July 2006 and May 2012, the initial group (RS and MRI available at initial diagnosis) and the post-CRT group (RS and MRI available after the completion of preoperative CRT) were selected.
