Abstract

Background: The COVID19 pandemic has resulted in a significant reduction in referrals to the colorectal cancer 2-week wait pathway. The aim of this study was to describe this 'missing cohort of referrals' by comparing the characteristics of referrals made during the pandemic with historic referrals. Methods: Demographics, index of multiple deprivation deciles (IMD), labs, faecal immunochemical tests (FIT) and cancer outcomes data of referrals between January 2015 and September 2020 were included. The historic cohort (Jan 2015 to Feb 2020) was compared with the pandemic cohort (Apr to Sep 2020). Referrals made in March 2020 were excluded. Results: 16704 referrals were included -14800 historic, 1583 pandemic and 321 excluded. There was no difference in age (median 69 years), gender (47% male), ethnicity (95% Caucasian), IMD (median 7) or cancer incidence (any malignancy 4.7% vs 5.0%, colorectal cancer 3.1% vs 3.9%). There were fewer referrals with iron-deficiency anaemia (11% vs 15%, P < 0.01) due to introduction of a separate pathway in 2019. FIT testing doubled during the pandemic (64% vs 31% in 2019, P < 0.001) after it was made mandatory. Conclusion: Clinical risk and outcome characteristics of pandemic referrals did not differ significantly from historic referrals. They were neither a selective high-risk cohort due to improved triage nor a low-risk cohort because of concerns of high-risk patients attending hospital during the pandemic. The 'missing cohort' are likely to have similar clinical characteristics as historic referrals including 5% cancer incidence and 10% polyp incidence. Urgent action is required to avoid further harm to these patients.

Abstract

Introduction\ud \ud Patients with cancer who develop small bowel obstruction are at high risk of malnutrition and morbidity following compromise of gastrointestinal tract continuity. This study aimed to characterise current management and outcomes following malignant small bowel obstruction.\ud \ud \ud \ud Methods\ud \ud A prospective, multicentre cohort study of patients with small bowel obstruction who presented to UK hospitals between 16th January and 13th March 2017. Patients who presented with small bowel obstruction due to primary tumours of the intestine (excluding left-sided colonic tumours) or disseminated intra-abdominal malignancy were included. Outcomes included 30-day mortality and in-hospital complications. Cox-proportional hazards models were used to generate adjusted effects estimates, which are presented as hazard ratios (HR) alongside the corresponding 95% confidence interval (95% CI). The threshold for statistical significance was set at the level of P ≤ 0.05 a-priori.\ud \ud \ud \ud Results\ud \ud 205 patients with malignant small bowel obstruction presented to emergency surgery services during the study period. Of these patients, 50 had obstruction due to right sided colon cancer, 143 due to disseminated intraabdominal malignancy, 10 had primary tumours of the small bowel and 2 patients had gastrointestinal stromal tumours. In total 100 out of 205 patients underwent a surgical intervention for obstruction. 30-day in-hospital mortality rate was 11.3% for those with primary tumours and 19.6% for those with disseminated malignancy. Severe risk of malnutrition was an independent predictor for poor mortality in this cohort (adjusted HR 16.18, 95% CI 1.86 to 140.84, p = 0.012). Patients with right-sided colon cancer had high rates of morbidity.\ud \ud \ud \ud Conclusions\ud \ud Mortality rates were high in patients with disseminated malignancy and in those with right sided colon cancer. Further research should identify optimal management strategy to reduce morbidity for these patient groups.

3. The introduction of an emergency safety protocol coupled with simulation training in robotic surgery, has enabled a more cohesive and efficient response to emergencies.

Abstract

With the increasing popularity of robotic surgery, arise a unique set of challenges. In-order to minimise the risk and optimise patient safety, teams need to anticipate these, plan and train to improve familiarity with the nuances of robotic surgery. Human factors and simulation training (ST) are now an integral part of surgery and we have extended these principles to our robotic practice. From our experience with emergencies and a thorough debrief, we have realised the importance of an emergency safety protocol (ESP) for the undocking of the robot, and how training with the correct systems in place optimises our non-technical skills and improves our efficiency. This protocol is used across all robotic specialties allowing for clear communication, situational awareness and role clarity, thereby reducing errors in a high-pressured environment. We aim to share our protocol, highlight the importance of ST and show that coupling of the ESP with ST, including addressing a disrupted power supply and how to avoid the resulting loss of image capture, is where our paper contributes to the current literature. There is a paucity in the literature regarding emergency undocking, and also techniques for avoiding power interruptions, for which we utilise the Uninterruptible Power Supply (UPS) system. By sharing experiences and systems used, we create an opportunity that will result in a culture of shared learning in the robotic community, thereby encouraging other robotic teams to review their protocols and training practices and adapt as necessary., (Copyright © 2021 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Abstract

A 62-year-old Asian man presented with a 3-month history of right iliac fossa pain which had progressively worsened over the last 3 weeks. All blood parameters were found to be unremarkable except for mildly elevated erythrocyte sedimentation rate. CT imaging demonstrated thickening of the ascending colon and caecum. Colonoscopic biopsies showed submucosal granulomas with features suggestive of schistosomiasis and parasite serology was positive for Schistosoma antibodies. He was treated with praziquantel and showed subsequent symptomatic and radiological improvement. However, he represented nearly 2 years later and underwent a right hemicolectomy for small bowel obstruction. The resected bowel showed an inflammatory caecal mass and a terminal ileal adenocarcinoma., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Abstract

Background: Short-term studies have shown that patients with type III intestinal failure often develop gallstones and have recommended prophylactic cholecystectomy. In this retrospective cohort study, we aimed to define the incidence and clinical consequences of cholelithiasis over an extended time period, in order to refine the role of prophylactic cholecystectomy in type III intestinal failure., Methods: Data were retrospectively collected from a prospectively maintained audit. Patients with intestinal failure for 5 years or more were included. Kaplan-Meier analysis was used to estimate cumulative incidence over time. Predictors of cholelithiasis were evaluated by Cox regression., Results: Between 1 January 1983 and 1 December 2008, 81 patients were commenced on parenteral support lasting 5 years or more. Of 63 patients with no pre-existing gallstones on imaging, 17 (27%) developed gallstones during a median observation period of 133 months. On Kaplan-Meier analysis, the incidence at 10 years was 21%; at 20 years, 38%; and at 30 years, 47%. Thirteen of the 17 had symptoms and ten required surgical and/or endoscopic intervention. Increased weekly calorific content (P 0.003) and the provision of parenteral lipids (P 0.003) were predictors of cholelithiasis on univariable Cox regression., Conclusion: Many patients with long-term intestinal failure develop gallstones over time, with a 20-year incidence of 38%. The majority of those have symptoms or complications and require intervention. Therefore, prophylactic en-passant cholecystectomy is justified when gallstones are present in type III intestinal failure, supporting routine pre-operative imaging of the gallbladder prior to abdominal surgery.
