Laparoscopic totally extraperitoneal hernia repair in patients with a history of previous abdominopelvic surgery.

A retrospective cohort study of patients undergoing laparoscopic inguinal hernia repair compared short- and long-term outcomes between individuals with or without history of previous abdominopelvic surgery, aiming to determine the feasibility of totally extraperitoneal (TEP) repair within this population. All patients who underwent elective TEP inguinal hernia repair by one consultant surgeon across three London hospitals from January 2017 to May 2023 were retrospectively analysed to assess perioperative outcomes. Two hundred sixty-two patients were identified, of whom two hundred forty-three (93%) underwent laparoscopic TEP repair. The most frequent complications were haematoma (6.2%) and seroma (4.1%). Recurrence occurred in four cases (1.6% of operations, 1.1% of hernias). One hundred eighty-four patients (76%) underwent day-case surgery. There were no mesh infections or explanations, vascular or visceral injuries, port-site hernias, damage to testicle, or persisting numbness. There were no requirements for blood transfusion, returns to theatre, or readmissions within 30 days. There was one conversion to open and one death within 60 days of surgery. Eighty-three (34%) had a history of previous AP surgery. There was no significant difference in perioperative outcomes between the AP and non-AP arms. This finding carried true for subgroup analysis of 44 patients whose AP surgical history did not include previous inguinal hernia repair and for those undergoing repair of recurrent hernia. In expert hands, laparoscopic TEP repair is associated with excellent outcomes and low rates of long-term complications, and thus should be considered as standard for patients regardless of a history of AP surgery.

Risks Factors Associated with the Development of Crohn's Disease After Ileal Pouch-Anal Anastomosis for Ulcerative Colitis: A Systematic Review and Meta-Analysis.

BACKGROUND: Following ileal pouch-anal anastomosis [IPAA] for ulcerative colitis [UC], up to 16% of patients develop Crohn's disease of the pouch [CDP], which is a major cause of pouch failure. This systematic review and meta-analysis aimed to identify preoperative characteristics and risk factors for CDP development following IPAA. METHODS: A literature search of the MEDLINE, EMBASE, EMCare and CINAHL databases was performed for studies that reported data on predictive characteristics and outcomes of CDP development in patients who underwent IPAA for UC between January 1990 and August 2022. Meta-analysis was performed using random-effect models and between-study heterogeneity was assessed. RESULTS: Seven studies with 1274 patients were included: 767 patients with a normal pouch and 507 patients with CDP. Age at UC diagnosis (weighted mean difference [WMD] -2.85; 95% confidence interval [CI] -4.39 to -1.31; p = 0.0003; I2 54%) and age at pouch surgery [WMD -3.17; 95% CI -5.27 to -1.07; p = 0.003; I2 20%) were significantly lower in patients who developed CDP compared to a normal pouch. Family history of IBD was significantly associated with CDP (odds ratio [OR] 2.43; 95% CI 1.41-4.19; p = 0.001; I2 31%], along with a history of smoking [OR 1.80; 95% CI 1.35-2.39; p < 0.0001; I2 0%]. Other factors such as sex and primary sclerosing cholangitis were found not to increase the risk of CDP. CONCLUSIONS: Age at UC diagnosis and pouch surgery, family history of IBD and previous smoking have been identified as potential risk factors for CDP post-IPAA. This has important implications towards preoperative counselling, planning surgical management and evaluating prognosis.

Comparing and contrasting clinical consensus and guidelines for anal intraepithelial neoplasia in different geographical regions.

Anal Squamous Cell Carcinoma (ASCC) is an uncommon cancer with a recognised precursor Anal Intraepithelial Neoplasia (AIN). Although there are consistent evidence-based guidelines for the management of ASCC, historically this has not been the case for AIN and as a result there have been geographical variations in the recommendations for the treatment of AIN. More recently there have been updates in the literature to the recommendations for the management of AIN. To assess whether we are now closer to achieving an international consensus, we have completed a systematic scoping review of available guidelines for the screening, treatment and follow-up of AIN as a precursor to ASCC. MEDLINE and EMBASE were systematically searched for available clinical guidelines endorsed by a recognised clinical society that included recommendations on either the screening, treatment or follow-up of AIN. Nine clinical guidelines from three geographical areas were included. The most recent guidelines agreed that screening for AIN in high-risk patients and follow-up after treatment was necessary but there was less consensus on the modality of screening. Six Guidelines recommended the treatment of high-grade AIN and four guidelines describe a follow-up protocol of patients diagnosed with AIN. There appears to be increasing consensus on the treatment and follow-up of patients despite a poor evidence base. There is still significant discrepancy in guidance on the method to identify patients at risk of ASCC and AIN despite consensus between geographical regions on which patient subgroups are at the highest risk.

Anal squamous cell carcinoma in a high HIV prevalence population.

Anal Squamous Cell Carcinoma (ASCC) is a rare cancer that has a rapidly increasing incidence in areas with highly developed economies. ASCC is strongly associated with HIV and there appears to be increasing numbers of younger male persons living with HIV (PLWH) diagnosed with ASCC. This is a retrospective cohort study of HIV positive and HIV negative patients diagnosed with primary ASCC between January 2000 and January 2020 in a demographic group with high prevalence rates of HIV. One Hundred and seventy six patients were included, and clinical data was retrieved from multiple, prospective databases. A clinical subgroup was identified in this cohort of younger HIV positive males who were more likely to have had a prior diagnosis of Anal Intraepithelial Neoplasia (AIN). Gender and HIV status had no effect on staging or disease-free survival. PLWH were more likely to develop a recurrence (p < 0.000) but had a longer time to recurrence than HIV negative patients, however this was not statistically significant (46.1 months vs. 17.5 months; p = 0.077). Patients known to have a previous diagnosis of AIN were more likely to have earlier staging and local tumour excision. Five-year Disease-Free Survival was associated with tumour size and the absence of nodal or metastatic disease (p < 0.000).

Unique case of herniated small bowel infarction within a colonic stomal prolapse.

The number of permanent colostomies carried out in the United Kingdom is approximately 6400 per year1. Stomal prolapse is a known complication of colostomy formation. We presented the first case of small bowel herniation into a healthy stomal prolapse with subsequent ischaemia of the herniated bowel in a 102-year-old patient. This rare sequela of a relatively common stomal complication highlights an important consideration when faced with a large prolapse presenting acutely. It also raises an important discussion point for the management of our ever-ageing patient population.

Exploiting opportunities for leadership development of surgeons within the operating theatre.

It is increasingly recognised that leadership skills are a key requirement in being successful in surgery, regardless of speciality and at all levels of experience and seniority. Where the emphasis was previously on technical ability, knowledge and diagnostic acumen, we now know that non-technical skills such as communication and leadership contribute significantly to patient safety, experience and outcomes, and should be valued. The operating theatre is a unique micro-environment which is often busier, noisier, more stressful and more physically demanding than the clinic or ward setting. As a result surgeons and their trainers, who are striving to develop leadership skills require an in-depth awareness of the challenges in this environment and the opportunities that arise from them to develop leadership effectively. This article outlines why leadership learning is so beneficial in the operating theatre, both for the team and the patient as well as what elements of daily routine activity such as the WHO checklist use, list-planning and audit can be exploited to transform the average busy operating theatre into a rich, learning environment for future leaders in surgery.

Building effective clinical teams in healthcare.

PURPOSE: This article aims to review teamwork and the creation of effective teams within healthcare. DESIGN/METHODOLOGY/APPROACH: By combining research material found in management, psychology and health services research the article explores the drivers increasing the importance of teamwork, reviews the current knowledge base on how to build a team and focuses on some of the barriers to effective team performance. FINDINGS: The simultaneous inflation of healthcare costs and necessity to improve quality of care has generated a demand for novel solutions in policy, strategy, commissioning and provider organisations. A critical, but commonly undervalued means by which quality can be improved is through structured, formalised incentivisation and development of teams, and the ability of individuals to work collectively and in collaboration. Several factors appear to contribute to the development of successful teams, including effective communication, comprehensive decision making, safety awareness and the ability to resolve conflict. Not only is strong leadership important if teams are to function effectively but the concept and importance of followership is also vital. RESEARCH LIMITATIONS/IMPLICATIONS: Building effective clinical teams is difficult. The research in this area is currently limited, as is the authors' understanding of the different requirements faced by those working in different areas of the health and social care environment. ORIGINALITY/VALUE: This article provides a starting place for those interested in leading and developing teams of clinicians.

A framework to establish a mentoring programme in surgery.

INTRODUCTION: Mentoring programmes help to facilitate the process of continuous professional development in surgery, providing an organizational structure around a mentor-mentee relationship which helps to develop the mentee. The lack of guidelines outlining how to set up such mentoring programmes, the fragmented inter-relationships of existing schemes and the lack of a unified strategy for their implementation are obstacles to the creation of such initiatives within many surgical departments. METHODS: We draw upon previous research, the experiences of certain authors and our own reflections to identify the key features of a surgical mentoring programme. RESULTS: We propose a ten step process which aims to encourage the development of formalised mentoring programmes in surgery. CONCLUSION: This outline may improve the delivery and effectiveness of mentoring programmes, which may ultimately enhance surgical training and hence quality of patient care.

Do miniaturized extracorporeal circuits confer significant clinical benefit without compromising safety? A meta-analysis of randomized controlled trials.

Miniaturized extracorporeal circulation (mECC) attempts to reduce the adverse effects of conventional extracorporeal circulation (CECC) bypass. However, the potential benefits remain unclear and safety concerns persist. A systematic literature review identified 29 studies incorporating 2,355 patients: 1,181 (50.1%) who underwent cardiac surgery with CECC and 1,174 (49.9%) with mECC. These were meta-analyzed using random effects modeling. Heterogeneity, subgroup analysis, and risk of bias were assessed. Primary endpoints were 30-day mortality, neurovascular compromise, and end organ dysfunction. Secondary endpoints were length of stay and transfusion burden. Miniaturized extracorporeal circulation significantly reduced postoperative arrhythmias (p = 0.03), but no significant difference in 30-day mortality, neurocognitive disturbance, cerebrovascular events, renal failure, or myocardial infarction was identified. Miniaturized extracorporeal circulation also significantly reduced mean blood loss (p < 0.00001) and number of patients transfused (p < 0.00001); however, duration of hospitalization, units transfused per patient, chest tube drainage, and revision for rebleeding remained unchanged. Subgroup analysis of larger studies (10 studies, n ≥ 31) showed mECC to significantly reduce ventilation period, hospital stay, and intensive care unit (ICU) stay. Similarly, a significant reduction in neurocognitive disturbance was seen in studies with closely matched demographic groups. Miniaturized extracorporeal circulation is not associated with increased cerebrovascular injury and may confer an advantage, reducing postoperative arrhythmia, blood loss, and transfusion burden.

Medical leadership: why it's important, what is required, and how we develop it.

Good medical leadership is vital in delivering high-quality healthcare, and yet medical career progression has traditionally seen leadership lack credence in comparison with technical and academic ability. Individual standards have varied, leading to variations in the quality of medical leadership between different organisations and, on occasions, catastrophic lapses in the standard of care provided to patients. These high-profile events, plus increasing evidence linking clinical leadership to performance of units, has led recently to more focus on leadership development for all doctors, starting earlier and continuing throughout their careers. There is also an increased drive to see doctors take on more significant leadership roles throughout the healthcare system. The achievement of these aims will require doctors to develop strong personal and professional values, a range of non-technical skills that allow them to lead across professional boundaries, and an understanding of the increasingly complex environment in which 21st century healthcare is delivered. Developing these attributes will require dedicated resources and the sophisticated application of a variety of different learning methodologies such as mentoring, coaching, action learning and networking.

How minimalized extracorporeal circulation compares with the off-pump technique in coronary artery bypass grafting.

Recognition of the adverse effects of conventional extracorporeal circulation (CECC) led to the development of alternative technologies and techniques to minimize their impact while maintaining circulation during coronary artery bypass grafting (CABG). Off-pump coronary artery bypass (OPCAB) grafting has become established as one such alternative and more recently minimalized extracorporeal circulation (MECC) circuits have been developed with the aim of providing circulatory support while minimizing the interface between blood and the foreign surfaces of the circuit that initiates the associated adverse effects of CECC. Recently, some authors have suggested that MECC may be an alternative to OPCAB in patients undergoing CABG; the aim of this article is to systematically analyze and compare the impact of CABG with MECC with that of OPCAB, studying the adverse outcomes related to CECC. We performed a systematic search to identify all studies directly comparing OPCAB and MECC. Endpoints were subcategorized into four key areas of interest: length of stay (LOS), hemorrhage, cerebrovascular injury, and 30-day mortality. Random effect modeling techniques were applied to identify differences in outcomes between the two groups. Six studies fulfilled the inclusion criteria, incorporating 2,072 patients of whom 930 underwent OPCAB and 1,142 underwent revascularization supported by MECC. We found no statistically significant difference in hospital or intensive care unit (ICU) LOS, blood loss, mean number of patients transfused, neurocognitive disturbance, or 30-day mortality between the two groups but a trend toward an increased number of cerebrovascular events in the MECC group was observed. The number of studies comparing these alternative techniques for coronary revascularization is small, and there is a lack of high-quality data. Currently, there seems little difference between MECC and OPCAB but larger randomized controlled trials focusing on high-risk patients are required.

Variations in the application of various perfusion technologies in Great Britain and Ireland--a national survey.

In an attempt to reduce the negative sequelae of cardiopulmonary bypass (CPB), a variety of new technologies have been created. This study investigates variations in the application of these technologies throughout Great Britain and Ireland (GB & I). All perfusion departments within GB & I were surveyed about equipment and technologies used in CPB. Eighty-five percent of units use a standard arterial line filter in all cases. Forty percent of units occasionally use leukocyte-depleting filters in various sites within the circuit. Sixteen percent always use some element of heparin-bonded circuit, but 62% never use them. Twenty-five percent use solely rotary pumps, 18% use solely centrifugal pumps, and 56% use both. Finally, 20% are now using minimal extracorporeal circulation in certain clinical scenarios. These decisions are most frequently affected by clinician preference and cost. This survey has highlighted significant variation in the utilization of various technologies used in CPB. While some variation between centers is to be expected, as innovative technologies are adopted at varying rates, surveys such as this are useful for alerting clinicians to gaps between evidence-based knowledge and clinical practice.
