Background Patients with familial adenomatous polyposis (FAP) are at increased risk of developing gastric adenomas. There is limited understanding of their clinical course and no consensus on management. We reviewed the management of gastric adenomas in patients with FAP from two centres. Patients and methods Patients with FAP and histologically confirmed gastric adenomas were identified between 1997-2018. Patient demographics, adenoma characteristics management/surveillance outcomes were collected. Results One hundred and four (49 female) of 726 patients (14%) were diagnosed with gastric adenomas at a median age of 47 years (range 19-80). The median size of gastric adenoma was 6mm (range 1.5-50mm); 64 (62%) patients had adenomas located distal to the incisura. Five (5%) patients had gastric adenomas demonstrating high grade dysplasia (HGD) on initial diagnosis, distributed equally within the stomach. The risk of HGD was associated with adenoma size (p=0.04). Of adenomas larger than 20mm, 33% contained HGD. Two patients had gastric cancer at initial gastric adenoma diagnosis. Sixty-three (61%) patients underwent endoscopic therapy for gastric adenomas. Complications occurred in three (5%) patients and two (3%) had recurrence, all following piecemeal resection of large (30-50mm) lesions. Three patients were diagnosed with gastric cancer during follow-up, a median of 66 months (range 66-115) after initial diagnosis. Conclusions In this series, we observed gastric adenomas in 14% of patients with FAP. Five per cent contained HGD; risk of HGD correlated with adenoma size. Endoscopic resection was feasible, with few complications and low recurrence rates, but does not completely eliminate the cancer risk.

Introduction Acute appendicitis is the most common general surgical emergency globally. Its etiology includes the presence of luminal obstruction by faecoliths, lymphoid hyperplasia, impacted stool, and rarely by appendiceal or caecal cancer. Malignancy related to acute appendicitis is usually seen in the older age group. Aim To identify the subset rate of patients operated for acute appendicitis who have appendiceal carcinoma and analyze the outcome of their post-operative management. Material and methods A retrospective study of a cohort of 529 patients aged > 40 diagnosed with acute appendicitis with subsequent appendectomy in the period between 1 January 2014 and 31 December 2019 at Basildon and Thurrock University Hospital, Essex, United Kingdom was conducted. We analyzed the clinical data of the cohort including demographic information, diagnosis, pre-operative imaging, histological diagnosis as well as post-operative management where indicated. Results The median age of patients was 54.5 years (range 40-92). The male to female ratio in the appendicectomy cohort was 1:1.1. About 45% were aged 40-49 years, 24.8% were aged 50-59 and 30.2% were ≥60 years. Post-operative histology revealed acute appendicitis in 82.4% of the group. In 11% of the patients, the histology revealed the presence of other benign pathology as mucocele of the appendix, acute diverticulitis, follicular hyperplasia, and fibrous obliteration. The diagnosis of appendicular malignancy was seen in 1.9%. Conclusion Incidental appendiceal cancers in the resected specimens after acute appendicitis are rare but may be associated with a poor prognosis. It is recommended to consider such diagnosis in particular when dealing with acute appendicitis in older patients with longer symptom history, and in presence of peri-appendicular mass.

Introduction Current NHS guidelines recommend that treatment of colorectal patients referred through the two-week wait referral system should occur within sixty two days from the date of referral. The COVID-19 pandemic which started in March 2020 has however led to significant delays in the delivery of health services, including colorectal cancer treatments. This study investigates the effects of delayed colorectal cancer treatments during the COVID pandemic on disease progression. Methods A retrospective chart review of 107 patients with histologically confirmed diagnosis of colorectal cancer was conducted. The occurrence of cancer upstaging after initial diagnosis was assessed and compared between patients with treatment delays and patients who received treatments within the period recommended by NHS guidelines. A logistic regression was performed to evaluate the association between treatment delays beyond 62 days and cancer upstaging. Results The median age of the cohort was 71.2 years and 64.5% of the patients were over 65 years. Treatment delays were observed in 53.3% of reviewed patients. Patients with treatment delays received cancer treatments 95.8 (31.0) days on average after referral, compared to 46.3 (11.5) days in patients who experienced no treatment delays (p-value<0.0001). 38.6% of patients with treatment delays experienced cancer upstaging by the time of treatment, compared to 20% in the non-delay group (p-value = 0.036). Patients who received treatment after sixty two days from date of referral were 3.27 times more likely to experience colorectal cancer upstaging compared to those who received timely treatments. Conclusion Although an effective response to the Covid-19 pandemic requires the reallocation of healthcare resources, there is a need to ensure that treatments and health outcomes of patients with chronic diseases such as colorectal cancer continue to be prioritized and delivered in timely fashion.

The endolymphatic administration of IL2 is associated with less toxicity than the intravenous route but still achieves a systemic effect; a lower tumour burden may prove more responsive to this therapy.

Objective Elective surgery came to a standstill during the first wave of COVID-19. The safe resumption of elective surgery with COVID-19 prevalent in the community remains a significant challenge. The aim of this study was to look into the outcomes of elective general surgery in a dedicated ‘Green Zone (GZ)’ during the second wave of COVID-19 in the United Kingdom. Method A ‘Green Zone’ pathway, meant to provide a COVID-free environment, was created. A retrospective review of prospectively collected data was done on consecutive patients who underwent an elective general surgical procedure at a single NHS trust over a six-month period (September 1, 2020, to February 28, 2021). The primary outcome was 30-day COVID-19 mortality. Secondary outcomes included 30-day non-COVID-19 mortality, readmissions, and complications. Results The study included 331 patients with a median age of 55 years (interquartile range, IQR, 41-67); 169 (51%) were females. The majority of the patients were American Society of Anaesthesiologists grade 2 (ASA 2; n=177, 53%) followed by ASA 3 (n=76, 23%). Forty-seven patients (14%) had been shielding earlier in the year. Most of the cases were day cases (n=224, 67%). There was no 30-day COVID-19 or non-COVID-19 mortality. One patient developed COVID-19 three weeks after the index operation. Thirty-day readmission and complication rate were 4% (n=14) and 6% (n=21). Most of the complications were Clavien-Dindo grade 2 (n=10, 3%) followed by an equal number of grades 1 and 3b (n=5, 1.5%). Conclusion This study has shown that a dedicated ‘Green Zone’ elective operating pathway is safe and feasible provided a balanced risk assessment approach is adopted.

Aim Nutrition is an important aspect in the patient’s road to recovery after any surgical procedure. Often there is a communication gap which is not beneficial for the patient. The aim of this audit was to evaluate the communication regarding patient nutrition requirements. Method All consecutive patients on a General surgical morning ward round were included. Four communication points were reviewed: Data was collected prospectively on a predesigned proforma. Results First Cycle: Second Cycle: Conclusion Nutrition in surgical patients is very important. It is proven that patients on ERAS programme have fewer complications, more rapid return to function and shorter hospital stay. Emphasis and education about the importance of nutrition is the way forward.
