Robotic ambulatory colorectal resections: a systematic review.

Colorectal surgery has progressed greatly via minimally invasive techniques, laparoscopic and robotic. With the advent of ERAS protocols, patient recovery times have greatly shortened, allowing for same day discharges (SDD). Although SDD have been explored through laparoscopic colectomy reviews, no reviews surrounding robotic ambulatory colorectal resections (RACrR) exist to date. A systematic search was carried out across three databases and internet searches. Data were selected and extracted by two independent reviewers. Inclusion criteria included robotic colorectal resections with a length of hospital stay of less than one day or 24 h. 4 studies comprising 136 patients were retrieved. 56% of patients were female and were aged between 21 and 89 years. Main surgery indications were colorectal cancer and recurrent sigmoid diverticulitis (43% each). Most patients had low anterior resections (48%). Overall, there was a 4% complication rate postoperatively, with only 1 patient requiring readmission due to postoperative urinary retention (< 1%). Patient selection criteria involved ASA score cut-offs, nutritional status, and specific health conditions. Protocols employed shared similarities including ERAS education, transabdominal plane blocks, early removal of urinary catheters, an opioid-sparing regime, and encouraged early oral intake and ambulation prior to discharge. All 4 studies had various follow-up methods involving telemedicine, face-to-face consultations, and virtual ward teams. RACrRs is safe and feasible in a highly specific patient population; however, further high-quality studies with larger sample sizes are needed to draw more significant conclusions. Several limitations included small sample size and the potential of recall bias due to retrospective nature of 2 studies.

Improving the Knowledge and Competency of UK Foundation Doctors in Nasogastric Tube Placement: A National Study.

Objective This study aims to improve foundation doctors' knowledge of guidelines for confirming nasogastric (NG) tube position and to enhance their confidence and competency in NG tube placement. Methods A three-part educational approach was designed, which included an educational leaflet and allowed the assessment of a participant's knowledge of guidelines pertaining to NG tube positioning before and after education. This educational leaflet and accompanying pre- and post-learning assessments were distributed among NHS Foundation Trusts in the UK between January 2022 and June 2022. All participants were foundation doctors in the UK. Those who had entered further training after the completion of their foundation training, at the time of assessment distribution, were excluded. Results A total of 173 participants completed this assessment. We found a significant increase in confidence among participants following the education (p<0.05). There was also a significant improvement in objective knowledge of guidelines on NG tube position confirmation following education (p<0.05). Conclusions Current knowledge on NG tube positioning is lacking among foundation doctors, but this can be significantly improved with simple educational leaflets. Furthermore, many participants felt that more training is needed, and this topic should be included in an essential teaching program.

Relationship between the m-FI 11 score and 2-year survival in octogenarians undergoing colorectal cancer resection.

Introduction: The modified Frailty Index (m-FI) offers a simple scoring tool, predicting short-term outcomes in elderly colorectal cancer (CRC) patients. However, links between m-FI scores and 2-year postoperative mortality in octogenarian CRC resection patients remain underexplored. A streamlined frailty index can aid in preoperative assessments to identify elderly patients who are likely to live longer after curative resection surgery to then tailor postoperative care. Our study aims to assess the association between m-FI scores and 2-year postoperative mortality in elderly CRC surgery patients. Methods: A retrospective analysis was conducted on a cohort of consecutive patients aged older than or equal to 80 years who underwent colorectal cancer resection at a tertiary referral centre between 2010 and 2017. The m-FI-11 scores less than or equal to two denoted the non-frail category, whereas m-FI scores equal to or exceeding 3 were categorised as frail. The primary outcome measure was defined as 2-year all-cause mortality. Results: A total of 337 patients were studied. The 2-year overall survival rate was 83% with an overall median survival time of 84 months (95% CI: 74-94 months). Patients with m-FI scores less than or equal to 2 had a 2-year survival rate of 85% and a median survival time of 94 months (95% CI: 84-104 months). Conversely, patients with m-FI scores greater than or equal to 3 had a 2-year survival rate of 72% and a median survival time of 69 months (95% CI: 59-79 months). An m-FI score greater than or equal to 3 showed a hazard ratio of 1.73 (95% CI: 0.92-3.26, P=0.092) for 2-year mortality compared to an m-FI score less than or equal to 2. Conclusion: Higher m-FI scores significantly correlate with an increased 2-year mortality risk among octogenarian CRC resection patients. This highlights the potential of the m-FI as a preoperative tool for identifying patients likely to survive longer post-surgery. Its integration aids in tailored postoperative care strategies, ensuring efficient recovery to functional baselines in this cohort.

Diverticulitis and Diverticulosis of the Appendix: A Case Series.

Introduction Diverticula of the appendix is a rare entity, may be complicated by inflammation/infection, and clinically mimics acute appendicitis. The reported associated risk factors include male gender, Hirschprung's disease, cystic fibrosis and adult age, where some reports claim that they are also associated with an increased risk of appendiceal malignancy. Imaging has a place in pre-operative diagnosis, however, most of the cases were diagnosed during a pathological examination after surgery. They are associated with a higher rate of perforation (more than four times compared with classical acute appendicitis). In this review, we present a case series of five patients diagnosed with diverticulitis and one with diverticulosis of the appendix that were managed at a single centre. Our aim is to explore the common clinical, radiological, and intra-operative findings associated with this disease as well as the outcome of management. Materials and methods A total number of six cases of diverticular disease of the appendix diagnosed and managed at Basildon University hospital in the period between 2016 and 2020 were studied. The demographic details and clinical data including presenting symptoms, laboratory results, radiological characteristics, intraoperative findings and histopathological features were analysed. Results The study group included four males and two females, with an age range of 20-84 years. The most common presenting clinical symptoms were right iliac fossa abdominal pain, nausea, anorexia, and diarrhoea. Half of the cases showed a thickened appendix in the pre-operative CT scan. An inflamed or perforated appendix was seen in five cases as well as inflammation of the diverticula. Conclusion Appendiceal diverticulitis is an uncommon pathology that imitates acute appendicitis, and appendicectomy is the standard treatment. Prophylactic appendicectomy is recommended for non-inflamed diverticula - this is due to the potential risk of inflammation, perforation, and the risk of developing an appendiceal neoplasm.

Chronic Pain as a Complication in Open Inguinal Hernia Repair: A Retrospective Study of Consenting Practice in a Single Centre.

Introduction Inguinal hernia repair is one of the most commonly performed procedures in general surgery in the United Kingdom. Chronic pain as a long-term postoperative complication of this procedure has been extensively documented in the literature. However, this complication is often undisclosed during the consenting process. This omission impairs the patients' informed decision-making process. The Montgomery v Lanarkshire Health Board case, in 2015, changed the way in which patient consent is viewed legally. This has made proper consent practices more important to surgeons undertaking procedures. Aim The objective is to assess if there has been an improvement in consenting practices by comparing consent forms from 2015 (the year of the Montgomery ruling) and 2019, specifically in regard to the risk of chronic groin pain following open inguinal hernia repair with mesh. Methods This was a retrospective review of patients who underwent open inguinal hernia repair using a prosthetic mesh in 2015 and 2019. The medical records were retrieved on the trust's electronic medical record system using the patient's hospital number. The following parameters were obtained: patient demographics, preoperative clinic letters, operation notes and consent forms. The clinic letters and consent forms were systematically reviewed for any mention of chronic groin pain. Results In 2015 and 2019, 163 and 56 open inguinal hernia repairs with mesh were performed, respectively. The median age of patients was 63 (28-88) and 64.5 (19-88) in the respective years. Throughout both years there was a predominance in male patients, and the majority of cases were performed on an elective basis. Consent for chronic pain was present in 60.7% and 62.5% of cases in 2015 and 2019, respectively (p=0.055). Conclusion Despite the importance of adequate consenting practice, we found no significant improvement in consenting practice for chronic pain following open inguinal hernia repair in the four years following the Montgomery ruling.

Thyroid Hemiagenesis: Narrative Review and Clinical Implications.

Thyroid Hemiagenesis (THA) is an uncommon, congenital anomaly defined by the absence of one thyroid lobe with or without the isthmus. Reports suggest it may be found more often in regions endemic for hypothyroidism. Genetic abnormalities are thought to have a role based on findings in monozygotic twins. Most cases are sporadic, however familiar clusters have also been documented. It is found more frequently in females. A majority of patients report no symptoms and THA is found incidentally during investigations or intraoperatively. THA is usually associated with normal thyroid function, but it can present with thyroid hypofunction. Since a majority of patients are asymptomatic, there are no specific recommendations for management. Ultrasound imaging and thyroid scintigraphy using technetium or iodine are useful in diagnosis. Its clinical importance occurs when the remnant thyroid lobe requires excision leading to the lifelong requirement for thyroxine supplementation. Published English literature (Medline, PubMed, and Embase databases) was searched. Medical subject headings (MeSH) terms used were "thyroid hemiagenesis," "one thyroid lobe," and "thyroid aplasia". Case reports, case series, and original articles were selected to provide a framework for this review. Articles reviewed were published in the past 20 years. The association of THA with thyroid cancer was explored. In this group, the F:M ratio was 3.25:1. Left THA constituted 53% of cases, right THA in 29.4%, and isthmus absence in 17.6% of cases. Also, the authors investigated the link between THA and hyperparathyroidism, both left and right THA are seen in an equal number of cases in the hyperparathyroidism subgroup. In patients with THA and Grave's disease, left THA was seen in a majority of cases (86.7%), while an equal number of left and right THA was observed in patients with Hashimoto's thyroiditis. In addition, congenital abnormalities associated with THA were observed, the left THA was seen in 60% and right THA in 40% of cases of this subgroup. The summative review provided a detailed insight into the epidemiology, aetiopathogenesis, genetics, symptomatology, diagnosis, and treatment for THA by combining findings and results from almost a hundred research papers from around the world. THA remains a poorly understood, often incidentally detected, abnormality in euthyroid patients undergoing investigations and treatment for other thyroid disorders.

Instituting a Green Zone for Elective Surgery During the Second Wave of COVID-19.

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.

Acute mesenteric ischaemia due to superior mesenteric vein (SMV) thrombosis.

A 77-year-old male patient presented with a 5-day history of abdominal pain, coffee ground vomiting and blood-stained diarrhoea. CT scan of the abdomen and pelvis demonstrated a long segment thrombotic occlusion of the superior mesenteric vein (SMV) extending up to the proximal portion of the portal vein causing significant acute small bowel ischaemia. Patient's deteriorating clinical condition warranted surgical management. Successful surgical management required multidisciplinary teamwork between emergency, vascular surgeons, anaesthetists and intensivists. Emergency laparotomy revealed gangrene of an estimated 120 cm of small bowel segment starting from duodenojejunal junction and a long segment thrombotic occlusion of the SMV extending up to the portal confluence. Resection of gangrenous small bowel without anastomosis and thrombo-embolectomy of SMV along with laparostomy was done at the initial operation. Patient was admitted in the intensive care unit on systemic heparinisation through intravenous administration of unfractionated heparin. Second relook exploration was done after 48 hours followed by anastomosis of the small bowel and closure of the abdomen. Patient made a good recovery following anticoagulation therapy and was discharged on postoperative day 10.

Lessons for Emergency Surgery in the Second Wave: One-Month Single-Centre Experience During the First Wave of COVID-19.

Introduction The global COVID-19 pandemic had a deleterious effect upon elective and emergency surgery. Focus of patient care was directed to emergency services. Association of Surgeons of Great Britain and Northern Ireland guidelines advised a trend towards conservative management. Traditional surgical intervention was reserved only for selected cases only. We evaluated our emergency practice over a four-week period during the first peak of COVID-19. Methods A retrospective single-centre analysis was performed of consecutive patients seen by the emergency general and vascular surgery on-call team in a District General Hospital over a four-week period (30 March 2020-26 April 2020). Primary outcome was 30-day COVID-19 mortality. Secondary outcomes were 30-day complications, readmission rate and non-COVID-19-related mortality. Adherence to intercollegiate guidelines was also assessed.  Results A total of 184 patients were assessed during the period. The median age was 55 years (interquartile range 34-75), with a male:female ratio of 1:0.7. Thirty-day COVID-19- and non-COVID-19-related mortalities were 3% and 8%, respectively. Thirteen percent of patients developed complications and 9% represented to the emergency department within 30 days. Conservative management was initially employed in 78% of patients. This had success rates in appendicitis and cholecystitis of 72% and 75%, respectively. A CT thorax was included in 89% having a CT abdomen and pelvis. Thirty-eight percent had a COVID-19 polymerase chain reaction (PCR) swab test performed throughout the study period. Fifty-two percent of individuals who underwent emergency surgery had a swab performed prior to operative intervention. Conclusions Conservative management seems to be reasonably effective and may re-shape the way we treat a proportion of surgical pathologies in the future. Further long-term data are required in order to evaluate this. A paucity of PCR testing was due to nationwide capacity shortcomings. This must be addressed in future peaks with rapid testing in order to triage patients to the appropriate setting.

Agile Application of Video Telemedicine During the COVID-19 Pandemic.

Background The coronavirus disease 2019 (COVID-19) pandemic led to a need to introduce video telemedicine for outpatients as an emergency measure without widespread stakeholder consultation. The patient and clinician experience of video outpatient consultation during the peak of the pandemic was studied for acceptability and to gather recommendations to improve the service during continuing infection control measures. Methods Outpatient video telemedicine was introduced over a 14-day period including the provision of equipment, systems integration and stakeholder communication. Patient and clinician experience were measured between 15 April 2020 and 5 May 2020. Results A total of 43 patients and 79 clinicians provided feedback. Of the patients, 86% were above the age of 30 years, with the largest patient group aged 51-70 years. Patient experience was positive. All (100%) patients found joining the video consultation easy; 93% of them recommended to use it for future consultations. Clinician satisfaction was >90% with sound and video quality. Patients were less satisfied than clinicians in that they had communicated everything they wanted to (86% versus 95%). All (100%) patients thought that the video telemedicine solution met their needs, but 25% of clinicians believed that the patient experience of a video consultation was worse than a face-to-face clinic appointment. The three significant factors identified for introducing video consultations were successful IT, improved patient experience and digital healthcare records. Conclusions In the COVID-19 crisis, video telemedicine played a central role in outpatient consultations with excellent levels of success. With some differences in satisfaction level, clinicians significantly underestimate the level of patient satisfaction with outpatient video consultation.

Informed Consent for Surgery at Resumption of Elective Activity After the First Wave of COVID-19.

Background The coronavirus disease 2019 (COVID-19) pandemic has changed the dynamics of healthcare, and the elective surgical consent process has also evolved. The Royal College of Surgeons of England published guidance on consent during COVID-19. Through this study, we aimed to assess our local consent adherence to these guidelines on the resumption of elective activity after the first wave of COVID-19. Methods This prospective review of consecutive elective surgical consent forms was conducted from 20 July 2020 to 16 August 2020 at the Princess Alexandra Hospital NHS Trust, England. The primary outcome was evidence of COVID-19 risk documentation on the consent forms. Results A total of 116 patients' consent forms were reviewed. Most patients were American Society of Anaesthesiologists (ASA) grade 2 (n=70; 60.34%). Only 25 consent forms (21.55%) had COVID -19 and its associated risks documented, with registrars being the most compliant (19/46; 41.3%) followed by consultants (6/51; 11.7%). With regards to the surgical sub-specialities, general surgery, orthopaedics and ENT had the highest compliance with the guidance. Conclusions As the elective activity resumes, peri-operative risks of COVID-19 should be weighted in during the informed consent process, as mentioned in the latest international guidelines on consent to avoid litigation and negligence claims.

Single centre concept of 'cold site' elective surgery during the peak of COVID-19 pandemic : A cohort study.

OBJECTIVE: The COVID-19 pandemic caused a major strain on healthcare systems across the globe. As these systems got overwhelmed with the emergency care of the infected patients, widespread cancellations of elective surgery occurred. Our hospital utilised local private hospital as a dedicated cold site (CS) for urgent elective surgery during the peak of the COVID-19 pandemic. We aim to analyse the outcomes at this dedicated cold site. METHOD: A retrospective review of a prospectively maintained database of all the cases operated at the CS during a 2-month period (30 March 2020 to 29 May 2020) was carried out. The primary outcome was 30-day COVID-19 related mortality. The secondary outcomes were 30-day non-COVID-19 related mortality, complications, readmission and development of COVID-19 symptoms. RESULTS: A total of 153 patients were operated at the CS over the study period with a median age of 57 years (Interquartile range, IQR 47-70). 62% were females and 82% had a Body Mass Index (BMI) less than 30. 73% of the operations were performed for cancer. 59% of the surgeries were graded as intermediate and 26% as major or complex. There was no mortality at 30 days from COVID-19 or non COVID-19 causes. There was only 1 (0.65%) readmission. 7 patients (4.57%) developed complications. 1 (0.65%) patient was diagnosed with COVID-19 in the postoperative period while 3 had COVID-19 symptoms but were tested negative. CONCLUSION: Urgent elective surgery is safe and feasible during the COVID-19 pandemic if a dedicated cold site is available.

An unexpected surprise: rare association of neuroendocrine tumours in inflammatory bowel disease.

Neuroendocrine neoplasms are rare malignancies, more so when cancerous metastasis occurs without a known primary source. Here we discuss a case of an ulcerative colitis sufferer, 43-year-old lady presented with what was thought to be a flare up. Situation deteriorated and was taken to theatre to find a significantly ischaemic colon, secondary to extensive venous thrombosis. The ischaemic bowel was resected alongside with what was thought to be a large, reactive lymph node. To our surprise, the resected lymph node returned with evidence of neuroendocrine neoplastic metastasis. Multiple laboratory and imaging investigations were performed in hope to identify the primary source. A second metastatic lymph node was identified and subsequently resected but the primary remains elusive. Currently, there are no visible evidences of active disease.

A cross-sectional survey on availability of facilities to healthcare workers in Pakistan during the COVID-19 pandemic.

INTRODUCTION: COVID-19 pandemic has caused a healthcare crisis across the world. Low-economic countries like Pakistan lag behind in an adequate response including supply of Personal Protective Equipment (PPE), leading to panic among healthcare workers. We aim to evaluate hospital settings and state in Pakistan regarding availability of resources and views of healthcare workers on COVID-19. METHOD: A questionnaire survey was carried out among healthcare workers in public and private sector hospitals across Pakistan for a period of one month. The primary measured outcomes were presence of local Standard Operating Procedures (SOPs), availability and training of PPE, specific isolation wards and staff wellbeing support by the hospital management. RESULTS: There were 337 participants, 307 (91.1%) doctors and 11 nurses (3.3%). About two-third of the participants (n = 199, 59%) reported non-availability of PPE and 40% (n = 136) denied availability of local Standard Operating Procedures. About a quarter of the participants (n = 94, 27.8%) had training in Donning and Doffing. Most of the participants (n = 277, 82.1%) felt that it was necessary to have testing available for frontline workers. CONCLUSION: There is lack of PPE and adequate facilities in hospitals as COVID-19 continue to spread in Pakistan. Local medical governing bodies and societies should come forward with guidelines to ascertain wellbeing of the healthcare workers.

COVID-19: Results of a national survey of United Kingdom healthcare professionals' perceptions of current management strategy - A cross-sectional questionnaire study.

OBJECTIVE: COVID-19 has caused a global healthcare crisis with increasing number of people getting infected and dying each day. Different countries have tried to control its spread by applying the basic principles of social distancing and testing. Healthcare professionals have been the frontline workers globally with different opinions regarding the preparation and management of this pandemic. We aim to get the opinion of healthcare professionals in United Kingdom regarding their perceptions of preparedness in their workplace and general views of current pandemic management strategy. METHOD: A questionnaire survey, drafted using Google Forms, was distributed among healthcare professionals working in the National Health Service (NHS) across the United Kingdom. The study was kept open for the first 2 weeks of April 2020. RESULTS: A total of 1007 responses were obtained with majority of the responses from England (n = 850, 84.40%). There were 670 (66.53%) responses from doctors and 204 (20.26%) from nurses. Most of the respondents (95.23%) had direct patient contact in day to day activity. Only one third of the respondents agreed that they felt supported at their trust and half of the respondents reported that adequate training was provided to the frontline staff. Two-thirds of the respondents were of the view that there was not enough Personal Protective Equipment available while 80% thought that this pandemic has improved their hand washing practice. Most of the respondents were in the favour of an earlier lockdown (90%) and testing all the NHS frontline staff (94%). CONCLUSION: Despite current efforts, it would seem this is not translating to a sense of security amongst the UK NHS workforce in terms of how they feel trained and protected. It is vital that healthcare professionals have adequate support and protection at their workplace and that these aspects be actively monitored.
