Abstract
PURPOSE Incisional hernia (IH) is a common complication following abdominal surgery. Surgical repair of IH is associated with the alleviation of symptoms and improvement of quality of life. Operative intervention can pose a significant burden to the patient and healthcare facilities. This study aims to describe and compare outcomes of elective and emergency surgical repair of IH. METHODS This study is a single-centre comparative retrospective study including patients who had repair of IH. Patients were divided into Group I (Emergency) and Group II (Elective), and a comparison was conducted between them. RESULTS Two hundred sixty-two patients were identified with a mean age of 61.8 ± 14.2 years, of which 152 (58%) were females. The mean BMI was 31.6 ± 7.2 kg/m2. More than 58% had at least one comorbidity. 169 (64.5%) patients had an elective repair, and 93 (35.5%) had an emergency repair. Patients undergoing emergency repair were significantly older and had higher BMI, p = 0.031 and p = 0.002, respectively. The significant complication rate (Clavien-Dindo III and IV) was 9.54%. 30 and 90-day mortality rates were 2.3% (n = 6) and 2.68% (n = 7), respectively. In the emergency group, the overall complications, 30-day and 90-day mortality rates were significantly higher than in the elective group, p ≤ 0.001, 0.002 and 0.001, respectively. Overall, 42 (16.1%) developed wound complications, 25 (9.6%) experienced a recurrence, and 41 (15.71%) were readmitted within 90 days, without significant differences between the two groups. CONCLUSION Patients who underwent emergency repair were significantly older and had a higher BMI than the elective cases. Emergency IH repair is associated with higher complication rates and mortality than elective repair.

Abstract
Abstract
Introduction
Over the last 20-years there has been increasing opioid related deaths, in the context of a worldwide epidemic of misuse including addiction and overdose. Startlingly, opioid commencement is usually iatrogenic. Most published data is from the USA with little evidence from UK surgical practice.
Method
Retrospective analysis of surgical unit opioid prescriptions. Data included opioids prescribed on discharge, 1, 3- and 6-months post-discharge usage and milligrams-of-morphine equivalence(mgEq) used to compare regimes.
Results
One hundred cases reviewed. 35% of patients were opioid naïve on admission and of these 20%, 5.71% and 8.57% remained on opioids at 1, 3- and 6-months post discharge respectively.
Females more likely to remain on long-term opioids at 6 months at lower doses (42% v 30%).
Only 6% of discharge summaries recommended GP follow-up and assessment of opioid requirements. Furthermore, none were prescribed a tapering dosage regime on-discharge.
Patients receiving Acute Pain Team reviews, more likely to remain on long-term opioids, at lower doses (30.67mgEq, 29.25mgEq and 32.63mgEq at 1-, 3- and 6-months post-discharge) compared to those without (69.16mgEq, 74.25mgEq and 65.13mgEq).
Only 11% of patients with pre-existing opioid prescriptions were reviewed by the acute pain team.
Worryingly, there was no documented assessment of opioid misuse risk in patients.
Conclusions
Standardised assessments i.e., opioid Risk Assessment Tools and mgEq need to be documented and monitored in primary and tertiary care. Acute pain team services should be offered to more patients. Our study hopes to raise awareness of the need for effective opioid stewardship in surgical patients.

Abstract
Abstract
Aim
We evaluated time to definitive treatment of Gallstone Pancreatitis (GSP) against the BSG guidelines during the first wave of COVID-19, comparing it to data of the same time period the previous year. Did the first wave of Covid-19 impact on time to intervention for patients diagnosed with GSP?
Method
Data were obtained retrospectively for 40 patients identified via the hospital coding department that presented with GSP between March 2019 - June 2019 and March 2020 – June 2020. Patient demographics, length of stay, time to intervention and re-admission awaiting intervention were recorded.
Results
Twenty-three patients were admitted during the non-COVID period. 30% (n = 7) of the non-COVID cohort had definitive management of GSP during index admission or within 2 weeks.
Seventeen patients were admitted during the first wave of Covid-19. 64.7% (n = 11) of the COVID-19 cohort had definitive management of GSP during the index admission or within 2 weeks.
Conclusions
Prior to COVID-19, we were not meeting guidelines for definitive management on index admission / within 2 weeks. During the first wave of COVID-19, more patients received definitive management of GSP during index admission / within 2 weeks than during the non-COVID period. A higher percentage of patients received surgical management within 2 weeks than in the non-COVID cohort. Those that did not receive management within 2 weeks, waited longer for intervention and had higher rates of re-admission than the non-COVID cohort. Despite anticipated future waves of COVID-19, prioritisation of urgent OP services is essential for those diagnosed with GSP to help reduce re-admission rates whilst awaiting intervention.

Abstract
Abstract
Background
Lymphadenectomy is central to tumor prognosis. 12 LNY during CRC resection is a standard of good oncological resection, but 30–50 percent of resections do not achieve this. LNR was suggested to be a more accurate predictive factor.
Aim
To examine the prognostic significance of LNY and LNR on survival in patients with non-metastatic CRC.
Method
A retrospective study on patients with CRC treated at a DGH from January 2015 to February 2017. Outcome measures were Disease-Free (DFS) and Overall Survival (OS).
Results
265 cases were identified. The mean age was (71.4±11.3) years with a median follow-up of 56 (range 0–72) months. Median LNY was 18 (range 0–66) nodes. 74.9% of the cases have> 12 LNY and only 25.1% of the cases have < 12 LN yielded in the specimen; however, 76.4% have LNR of 0-<0.25. Increasing LNR was associated with poorer OS and
DFS (p-value 0.0001). An LNR of (0.75–1) was associated with a very poor prognosis (p-value 0.0001); it showed 30 and 33 months less in median OS and DFS retrospectively than LNR
(0-<0.25). LNY did not show any statistically significant predictive factor in survival.
Multivariate analysis showed OS and DFS are affected (R2 = 27.3% and 26.1% retrospectively) mainly by LNR. It did not show statistical significance with the other variables, including TNM, LNY, and Dukes' stages.
Conclusions
Increasing LNR was a marker of poor survival; however, LNY was not a statistically significant predictive factor. LNR is better in predicting survival than TNM and Dukes' staging.

Abstract
Abstract
Introduction
Post-operative pain relief commonly involves opiates. Rising concerns about misuse has increased scrutiny of prescribing practices. In the UK, 12.5% of prescriptions are for opiates. In the US, the Department of Health and Human Services has declared an epidemic of opiate misuse. We aimed to evaluate opiate prescribing practices post-operatively, within a UK teaching hospital, and establish the risk of prolonged opiate use.
Method
A pan-speciality retrospective observational cohort study was performed. Patients who underwent surgery in the year 2018 were included. Patients were opiate naïve if their admission Medicine reconciliation and GP record described no opiates for the previous year. Endpoints: the proportion of patients discharged with opiates and the proportion of patients remaining on opiates at 1- and 2-years post admission.
Results
20526 operations were performed on 17524 patients, across pan-specialities. 8772 patients were discharged on opiates. 673 required further opiates from their GP after discharge, of which 331 were previously opiate naive. At 1 year post op, 180 previously naive patients remained on opiates.
Conclusions
Attention needs to be given to the risk of developing opiate dependence post-operatively. An evidence-based approach should support clinicians in preventing an opiate crisis in the UK.

Abstract
Establishing cell lines is a good model for experimental applications to study molecular mechanisms and cell-specific gene expression. Equids have a diffuse epitheliochorial placenta, where the invasive trophoblast is represented by the chorionic girdle (CG) and the noninvasive trophoblast by the allantochorion (AC). Embryonic CG cells are unique to horses and have a crucial role in equine chorionic gonadotropin (eCG) production and maintenance of pregnancy during the first trimester. This study had three objectives: (1) establishing a stable cell line from Day 30 CG cells and AC using lentivirus encoding hTERT; (2) characterisation of Day 30 CG cells and AC cell morphology and expression of eCG α (eCGA) and β (eCGB) subunits, major histocompatibility complex class II (MHCII), and Kisspeptin receptor (KISS1R) in CG and AC cells; (3) investigating eCG protein production invitro from Day 30 CG and AC cells. Three mares (n=3) were used to collect Day 30 conceptuses by non-surgical uterine lavage on Day 30 of pregnancy. All 3 conceptuses were dissected for CG and AC cells then cultured invitro to confluency in cell culture plates. Second-generation lentiviral particles were generated using a three-vector system including transfer vector pLV-hTERT-IRES-hygro, and human telomerase reverse transcriptase (hTERT) lentivirus was utilised to establish stable hygromycin-resistant equine embryonic cell lines. Reverse-transcription PCR (RT-PCR) was used to study gene expression in cells and radioimmunoassay was used to investigate protein presence in the media. We established a hygromycin-resistant Day 30 CG and AC cell lines that express eCGA, eCGB, and hTERT and confirmed using RT-PCR yielding the predicted bands. The cell lines were maintained for 16 passages (7±2 days/passage), 10 of which were cultured after the lentiviral infection steps. Also, we characterised CG cells as fast-growing, large, binucleated, and epithelioid, and AC cells as rapid-growing showing smaller, squamous, mononucleate, epithelioid, and elongated fibroblastic cells. The RT-PCR results showed eCGA and eCGB subunits are expressed by both Day 30 CG and AC cells, but MHCII and KISS1R genes were not expressed in either of cells. Moreover, radioimmunoassay results showed that Day 30 CG cells did produce eCG protein (35.42ngmL−1) invitro earlier than what previous literature has shown. However, Day 30 AC cells did not produce eCG protein (0.042ngmL−1) invitro, and both CG and AC cell lines stopped secreting eCG in the media after the lentiviral infection. To conclude, establishing stable and hygromycin-resistant cell lines from Day 30 equine CG and AC cells using lentivirus encoding pLV-hTERT-IRES-hygro is attainable. Also, equine chorionic gonadotropin eCG protein is produced invitro as early as Day 30 from CG cells.

Abstract
Aim To determine whether the introduction of a clinical pathway for the treatment of pyelonephritis in obstetric patients would improve outcomes. Methods This was a retrospective study conducted in a maternity hospital using quantitative analysis methods. Patients who met laboratory and clinical criteria for pyelonephritis during data collection were included. Results The study included analysis of 23 patients pre-intervention and 19 post-intervention. Baseline and patient characteristics were similar for both groups. A statistically significant difference was seen in 3 of 7 outcome measures. Increased use of gentamicin (13% Vs 52% p=0.006), Increased number of renal ultrasounds (17% Vs 47%, p=0.04) and increased use of prophylaxis (21% Vs 68%, p=0.003). The proportion of patients receiving ≥ 10 days of IV antimicrobials decreased from 48% to 21% post-intervention (p=0.07). Discussion This study has shown that the introduction of a pathway for the treatment of pyelonephritis in pregnancy had a positive impact on several important clinical outcomes.

Abstract
Background Treatment options for achalasia include endoscopic and surgical techniques that carry the risk of esophageal bleeding and perforation. The rare coexistence of esophageal varices has only been anecdotally described and treatment is presumed to carry additional risk. Methods Experience from physicians/surgeons treating this rare combination of disorders was sought through the International Manometry Working Group. Results Fourteen patients with achalasia and varices from seven international centers were collected (mean age 61 ± 9 years). Five patients were treated with botulinum toxin injections (BTI), four had dilation, three received peroral endoscopic myotomy (POEM), one had POEM then dilation, and one patient underwent BTI followed by Heller's myotomy. Variceal eradication preceded achalasia treatment in three patients. All patients experienced a significant symptomatic improvement (median Eckardt score 7 vs 1; p < 0.0001) at 6 months follow-up, with treatment outcomes resembling those of 20 non-cirrhotic achalasia patients who underwent similar therapy. No patients had recorded complications of bleeding or perforation. Conclusion This study shows an excellent short-term symptomatic response in patients with esophageal achalasia and varices and demonstrates that the therapeutic outcomes and complications, other than transient encephalopathy in both patients who had a portosystemic shunt, did not differ to disease-matched patients without varices.

Abstract
Background Intrapapillary capillary loops (IPCLs) represent an endoscopically visible feature of early squamous cell neoplasia (ESCN) which correlate with invasion depth - an important factor in the success of curative endoscopic therapy. IPCLs visualised on magnification endoscopy with Narrow Band Imaging (ME-NBI) can be used to train convolutional neural networks (CNNs) to detect the presence and classify staging of ESCN lesions. Methods A total of 7046 sequential high-definition ME-NBI images from 17 patients (10 ESCN, 7 normal) were used to train a CNN. IPCL patterns were classified by three expert endoscopists according to the Japanese Endoscopic Society classification. Normal IPCLs were defined as type A, abnormal as B1-3. Matched histology was obtained for all imaged areas. Results This CNN differentiates abnormal from normal IPCL patterns with 93.7% accuracy (86.2% to 98.3%) and sensitivity and specificity for classifying abnormal IPCL patterns of 89.3% (78.1% to 100%) and 98% (92% to 99.7%), respectively. Our CNN operates in real time with diagnostic prediction times between 26.17 ms and 37.48 ms. Conclusion Our novel and proof-of-concept application of computer-aided endoscopic diagnosis shows that a CNN can accurately classify IPCL patterns as normal or abnormal. This system could be used as an in vivo, real-time clinical decision support tool for endoscopists assessing and directing local therapy of ESCN.

Abstract
INTRODUCTION Emergency laparotomy in the elderly is an increasingly common procedure which carries high morbidity and mortality. Risk prediction tools, although imperfect, can help guide management decisions. Novel markers of surgical outcomes may contribute to these scoring systems. The neutrophil:lymphocyte ratio (NLR) and CRP:albumin ratio (CAR) have been associated with outcomes in malignancy and sepsis. We assessed the use of ratio NLR and CAR as prognostic indicators in patients over the age of 80 undergoing emergency laparotomy. METHODS A retrospective analysis of all patients over the age of 80 who underwent emergency laparotomy during a 3 year period was conducted. Pre and post-operative NLR and CAR were assessed in relation to outcome measures including inpatient, 30-day and 90-day mortality. Statistical analysis was conducted with Mann-Whitney U, receiver operating characteristics, Spearmans rank correlation coefficient and chi-squared tests. RESULTS One hundred and thirty-six patients over the age of 80 underwent emergency laparotomy. Median age was 84 years (range 80-96 years). Overall inpatient mortality was 19.2%. Pre-operative and post-operative NLR and CAR were significantly raised in patients with sepsis v no sepsis (p < 0.05). Pre-operative NLR was significantly associated with inpatient (p = 0.046), 30-day (p = 0.02) and 90-day mortality (p = 0.01) in patients with visceral perforation. A pre-operative NLR value of greater than 8 was associated with significantly increased mortality (p = 0.016, AUC:0.78). CAR was not associated with mortality. CONCLUSION Pre-operative NLR is associated with mortality in patients with visceral perforation undergoing emergency laparotomy. NLR > 8 is associated with a poorer outcome in this group of patients. CAR was not associated with mortality in over-80s undergoing emergency laparotomy.

Abstract
BACKGROUND Solid organ transplant recipients have an increased cancer risk owing to immunosuppression and oncogenic viral infections. We report on the incidence and types of bladder cancer in kidney transplant recipients in Ireland, describing possible additional risk factors and outcomes in these patients. METHODS We identified kidney transplant recipients diagnosed with de novo bladder cancer between January 1, 1994, and July 31, 2012, by integrating data from the Irish National Cancer Registry and National Renal Transplant Registry. We calculated the standardized incidence ratio (SIR) and examined patient and tumor characteristics and 1-year survival rate. RESULTS Fifteen patients were diagnosed with de novo bladder cancer during the study period, representing 0.48% of kidney transplant recipients. The SIR was 2.5 (95% CI, 1.4-4.2; P < .001). The mean interval between transplantation and diagnosis of bladder tumor was 8.6 years and mean age at time of diagnosis was 55.7 years. Sixty percent of patients were male. The tumor types were transitional cell carcinoma (9 patients), squamous cell carcinoma (3 patients), adenocarcinoma (1 patient), carcinoma in situ (1 patient), and diffuse large B-cell lymphoma (1 patient). Beside immunosuppression, risk factors associated with bladder cancer were urogenital disease (6 patients), cyclophosphamide exposure (2 patients), BK nephropathy (1 patient), analgesic nephropathy (1 patient), and extensive smoking (1 patient). Eight patients underwent radical cystectomy for invasive tumors, with resection of other pelvic organs in 7 patients. Mortality rate within the first year was 40%. CONCLUSION Bladder cancer occurred more commonly in kidney transplant recipients with a predominance of aggressive tumors and a high mortality. In patients with preexisting risk factors such as urologic abnormalities and cyclophosphamide exposure careful assessment before transplantation and vigilant monitoring posttransplantation with a low threshold for cystoscopy may improve outcomes.

Abstract
Organ Donation following the Circulatory determination of Death was introduced in Beaumont Hospital during 2011. The Intensive Care Society of Ireland formally endorsed a national DCD clinical practice guideline in 2012. This retrospective audit covers a 2-year period during which eleven patients were considered suitable for DCD and where consent was obtained. Nine patients died within the ninety-minute period following the withdrawal of life sustaining therapies and subsequently donated organs (82%). Eighteen kidneys were recovered and seventeen patients received renal transplants--one patient received a nephron-dosing dual renal transplant. Lungs were recovered on two occasions and one patient received a lung transplant. Heart valves were recovered on one occasion. To date sixteen of seventeen recipient patients have functioning renal transplants (94%). In conclusion, this model of deceased donation has proven acceptable to families, nursing and medical staff and the outcomes reported are consistent with international best practice.

Abstract
There have been few studies of patients with renal allografts functioning for more than 20 years. We sought to identify clinical factors associated with ultra long-term (>20 year) renal allograft survival and to describe the clinical features of these patients. We performed a retrospective analysis of the Irish Renal Transplant Database and included 1174 transplants in 1002 patients. There were 255 (21.74%) patients with graft function for 20 years or more. Multivariate analysis identified recipient age (HR 1.01, CI 1.01-1.02), gender (male HR 1.25, CI 1.08-1.45), acute rejection (HR 1.26, CI 1.09-1.45) and transplant type (living related donor vs. deceased donor) (HR 0.52, CI 0.40-0.66) as significantly associated with long-term graft loss. Median serum creatinine was 115 μmol/L. The 5-year graft survival in 20-year survivors was 74.7%. The mean age at death was 62.7 years (±10.6). The most common causes of death were cardiovascular disease and malignancy. The two major causes of graft loss were death (with function) and interstitial fibrosis/tubular atrophy. Comorbidities included skin cancer (36.1%), coronary heart disease (17.3%) and other malignancies (14.5%). This study identifies factors associated with long-term allograft survival and a high rate of morbidity and early mortality in long-term transplant recipients.

Abstract
Pressure related complications such as abdominal wall hernias occur with relative frequency in patients on peritoneal dialysis. Less frequently, a transudative pleural effusion containing dialysate can develop. This phenomenon appears to be due to increased intra-abdominal pressure in the setting of congenital or acquired diaphragmatic defects. We report three cases of pleuroperitoneal leak that occurred within a nine-month period at our institution. We review the literature on this topic, and discuss management options. The pleural effusion resolved in one patient following drainage of the peritoneum and a switch to haemodialysis. One patient required emergency thoracocentesis. The third patient developed a complex effusion requiring surgical intervention. The three cases highlight the variability of this condition in terms of timing, symptoms and management. The diagnosis of a pleuroperitoneal leak is an important one as it is managed very differently to most transudative pleural effusions seen in this patient population. Surgical repair may be necessary in those patients who wish to resume peritoneal dialysis, or in those patients with complex effusions. Pleuroperitoneal leak should be considered in the differential diagnosis of a pleural effusion, particularly a right-sided effusion, in a patient on peritoneal dialysis.
