Global Impact of COVID-19 on Colorectal Cancer Screening: Current Insights and Future Directions

The coronavirus disease 2019 (COVID-19) pandemic has brought significant challenges to many aspects of healthcare delivery since the first reported case in early December 2019. Once in the body, SARS-CoV-2 can spread to other digestive organs, such as the liver, because of the presence of ACE2 receptors. Colorectal cancer (CRC) remains the second-leading cause of death in the United States (US). Therefore, individuals are routinely screened using either endoscopic methods (i.e., flexible sigmoidoscopy and colonoscopy) or stool-based tests, as per the published guidelines. At the beginning of the COVID-19 pandemic, the Centers for Medicare and Medicaid Services (CMS) recommended that all non-urgent surgical and medical procedures, including screening colonoscopies, be delayed until the pandemic stabilization. This article aims to review the impact of COVID-19 on CRC screening.

EP.TU.170Audit to assess the management of patients presenting with lower gastrointestinal (LGI) bleeds in the Trust

Aims To identify presentations of LGI bleeds, assimilate learning and make appropriate recommendations to improve management in hospital. Methods 336 patients with ‘PR bleed’ on their coding summary in 2019 were identified. Data obtained through eCare and EDM was analysed as outlined: Results 69% were emergency presentations of LGI bleed and the remaining 31% were elective admissions. 5% of emergency LGI bleed patients were discharged on the same day as compared to 97.4% of elective patients. The remaining 80% of emergency patients went on to have outpatient investigations. Positive cases included haemorrhoids, inflammatory bowel disease and diverticulitis. Conclusions All emergency presentations occurred during inpatient stay creating disparities in manner of presentation and duration of admission between cohorts. However, outcomes between the cohorts were broadly similar, suggesting absence of significant disparities in management. Colonoscopy is the gold standard diagnostic investigation in LGI bleeds however, flexible-sigmoidoscopy can be considered in under 50’s. 80% of patients had a colonoscopy during admission as per guidelines. No reasoning was documented for patients who underwent other methods of investigation as first-line, thus creating a need for improved documentation when deviating from guidelines. Recommendation to re-audit in 1 year to assess changes.

TP1.2.7The stuck colonoscope

Background With the increased awareness and push for earlier diagnosis of colorectal cancer, the number of patients undergoing colonoscopy is increasing. Being a common condition, a number of these patients will have herniae. We describe a rare complication during a Sigmoidoscopy in a patient with an Inguinal hernia. The case A 75-year-old man was booked for a flexible sigmoidoscopy for rectal bleeding. The scope was successfully inserted to the Splenic flexure. During withdrawal, the scope stopped moving. It was still possible to advance the scope, but not to withdraw. The patient confirmed the presence of a left inguinal hernia. Physical examination and the position on magnetic scope imager confirmed the loop in the hernia. Various manoeuvres to withdraw the scope were unsuccessful. A colleague was called for a second opinion. We came up with a plan to maintain a ‘long loop‘ position in the hernia, by holding the scope through the scrotum and allowing it to slide on withdrawal. This was successful and the patient was discharged. Discussion Incarceration of the scope in the hernia occurs when the hernial defect permits entry and exit of the scope, leaving a loop in the hernia, in a long loop position. During withdrawal, the configuration changes to a short loop, crowding the hernial defect, preventing the scope from sliding. On searching literature, we found that this technique has been described by Koltun et al and is known as the “Pulley” technique. We suggest that colonoscopists are familiar with this technique.

EP.FRI.971 Is routine endoscopic evaluation of the colon necessary after an episode of acute diverticulitis?

Aim Currently standard practice is for patients diagnosed with diverticulitis to undergo endoscopic evaluation of the colon following the acute episode. The primary aim of endoscopy is to exclude underlying malignancy which may have been undetectable on initial CT scanning. We aim to determine if endoscopic evaluation of the colon is necessary for all patients. Methods All patients with CT proven diverticulitis were included between May 2017 and July 2018. Medical records, CT and endoscopy reports of 154 consecutive patients were retrospectively reviewed. Based on the CT reports, diverticulitis was classified as either uncomplicated (colonic wall thickening, pericolic fat stranding) or complicated (perforation, abscess, generalised free air and/or fluid). Results There were 154 patients included in the study. 59% percent were male. Median age at the time of diagnosis was 56 years old. There were 114 patients with uncomplicated and 40 patients with complicated diverticulitis. 79 patients (50 flexible sigmoidoscopy, 29 colonoscopy) with uncomplicated diverticulitis and 21 patients (15 flexible sigmoidoscopy, 6 colonoscopy) with complicated diverticulitis underwent endoscopy. Of the patients that underwent endoscopy, one patient (1.3%) with uncomplicated disease and one patient (4.8%) with complicated disease were found to have colorectal cancer (both rectal). Neither of these were associated with the diverticular segment. Conclusions Our data shows that routine endoscopic evaluation of the colon after an episode of acute diverticulitis may not be necessary in all cases. Patient numbers in this study are small therefore further work is required to draw conclusions which could influence future clinical practice.

EP.FRI.248 The bezoar, the bowel, and the blockage: A rare case of a spontaneously passed phytobezoar

Background Bezoar, from the Persian meaning antidote, denotes a trapped mass in the gastrointestinal system. There are several types, but here we present a case of phytobezoar. A phytobezoar is one which is composed of undigestible plant material. While all bezoars account for less than 4% of intestinal obstruction, most occur within the stomach or small intestine. Phytobezoars causing large bowel obstruction appear to be extremely rare. Case report We present a case of a phytobezoar causing large bowel obstruction in a 29-year-old man. He presented with a four-day history of abdominal pain and distension with associated vomiting and no bowel opening. An abdominal X-ray demonstrated significant dilatation of transverse colon. Subsequent CT revealed large bowel obstruction with transition point in the distal sigmoid. An intraluminal lesion, with mottled appearance, containing locules of gas – a phytobezoar – was noted as the cause. The Patient was clinically well with no peritonism and planned for a flexible sigmoidoscopy in the first instance. However, the patient went on to pass two large, hard bowel motions leading to significant resolution of symptoms. A flexible sigmoidoscopy was carried out to exclude other pathology and demonstrated that the obstruction had been relieved. Conclusion While it seems phytobezoar is an incredibly rare cause for large bowel obstruction, most of the literature suggests operative management of the problem by means of laparotomy and enterotomy. This case demonstrates the potential for conservative management and possibility for spontaneous resolution, despite emergency presentation.
