Abstract
AIMS To evaluate comparative outcomes of laparoscopic spleen-preserving distal pancreatectomy (LSPDP) and laparoscopic distal pancreatectomy with splenectomy (LDPS). METHODS A systematic search of multiple electronic data sources and bibliographic reference lists were conducted. Comparative studies reporting outcomes of LSPDP and LDPS were considered followed by evaluation of the associated risk of bias according to ROBINS-I tool. Perioperative complications, clinically important postoperative pancreatic fistula (POPF), infectious complications, blood loss, conversion to open, operative time and duration of hospital stay were the investigated outcome parameters. RESULTS Nineteen studies were identified enrolling 3739 patients of whom 1860 patients underwent LSPDP and the remaining 1879 patients had LDPS. The patients in the LSPDP and LDPS groups were of comparable age (p = 0.73), gender (p = 0.59), and BMI (p = 0.07). However, the patient in the LDPS group had larger tumour size (p = 0.0004) and more malignant lesions (p = 0.02). LSPDP was associated with significantly lower POPF (OR:0.65, p = 0.02), blood loss (MD:-28.30, p = 0.001), and conversion to open (OR:0.48, p < 0.0001) compared to LDPS. Moreover, it was associated with significantly shorter procedure time (MD: -22.06, p = 0.0009) and length of hospital stay (MD: -0.75, p = 0.005). However, no significant differences were identified in overall perioperative (OR:0.89, p = 0.25) or infectious (OR:0.67, p = 0.05) complications between two groups. CONCLUSIONS LSPDP seems to be associated with lower POPF, bleeding and conversion to open compared to LDPS in patients with small-sized benign tumours. Moreover, it may be quicker and reduce hospital stay. Nevertheless, such advantages are of doubtful merit about large-sized or malignant tumours. The available evidence is subject to confounding by indication.

Abstract
AIMS To evaluate short-term clinical and long-term survival outcomes of pancreatic resection for pancreatic metastasis from renal cell carcinoma (RCC). METHODS A retrospective evaluation of patients undergoing pancreatic resection for metastasis from RCC over a 12-years period was conducted. Furthermore, a systematic search of electronic data sources and bibliographic reference lists were conducted to identify studies investigating the same clinical question. Short-term clinical and long-term survival outcomes were evaluated. Kaplan-Meier survival plots were constructed for survival outcomes. Cox-proportional regression analysis was performed to determine factors associated with survival. Finally, meta-analysis of survival outcomes was conducted using random-effects modelling. RESULTS Eighteen patients underwent pancreatic resections for RCC pancreatic metastasis within the study period. The mean age of the included patients was 63.8 ± 8.0 years. There were 10(55.6 %) male and 8(44.4 %) female patients. Pancreatectomy was associated with 4(25.0 %) Clavien-Dindo (C-D) I, 5(31.3 %) C-D II, and 7(43.7 %) C-D III complications, 7(38.8 %) pancreatic fistula, 3(16.7 %) post-pancreatectomy acute pancreatitis, 1(5.6 %) delayed gastric emptying, and 1(5.6 %) chyle leak. The mean length of hospital stay was 18 ± 16.3 days. The median survival was 64 months (95 % CI 60-78). The 3-and 5-year disease-free survival rates were 83.3 % and 55.5 %, respectively. The 3-and 5-year survival rates were 100 % and 55.6 %, respectively. The pooled analyses of 553 patients demonstrated 3-and 5-year survival rates of 77.6 % and 60.7 %, respectively. CONCLUSIONS Pancreatectomy for RCC metastasis is associated with acceptable short-term clinical and promising long-term survival outcomes. Considering the rarity of the entity, escalation of level of evidence in this context is challenging.

Abstract
BACKGROUND To evaluate comparative outcomes of pancreatic cancer resection with or without adjuvant chemotherapy in patients with stage I pancreatic cancer. METHODS A systematic search of MEDLINE, CENTRAL, and Web of Science and bibliographic reference lists were conducted. All comparative studies reporting outcomes of pancreatic cancer resection for stage I cancer with or without adjuvant chemotherapy were included, and their risk of bias was assessed using the Risk Of Bias In Non-randomized Studies-of Interventions tool. Survival outcomes were analyzed using the hazard ratio and odds ratio for the time-to-event and dichotomous outcomes, respectively. RESULTS We included 6 comparative studies reporting a total of 6,874 patients with resected stage 1 pancreatic cancer, of whom 3,951 patients had no adjuvant chemotherapy, and the remaining 2,923 patients received adjuvant chemotherapy. The use of adjuvant chemotherapy was associated with significantly higher overall survival (hazard ratio 0.71, 95% confidence interval 0.62-0.82, P < .00001) and 2-year survival (65.1% vs 57.4%, odds ratio 1.99; 95% confidence interval 1.01-1.41, P = .04) compared to no use of adjuvant chemotherapy. However, there was no statistically significant difference in 1-year (86.8% vs 78.4%, odds ratio 1.60; 95% confidence interval 0.72-3.57, P = .25), 3-year (46.0% vs 44.0%, odds ratio 1.07; 95% confidence interval 0.90-1.29, P = .43), or 5-year survival (24.8% vs 23.3%, odds ratio 1.03; 95% confidence interval 0.80-1.33, P = .81) between the 2 groups. CONCLUSION Meta-analysis of best available evidence (level 2a with low to moderate certainty) demonstrates that adjuvant chemotherapy may confer survival benefits for stage I pancreatic cancer when compared to the use of surgery alone. Randomized control trials are required to escalate the level of evidence and confirm these findings with consideration of contemporary chemotherapy agents and regimens.

Abstract
OBJECTIVES To evaluate the ability of the c-reactive protein-to-albumin ratio (CAR) in predicting outcomes in patients undergoing pancreatic cancer resection. METHODS A systematic search of electronic information sources and bibliographic reference lists was conducted. Survival outcomes and perioperative morbidity were the evaluated outcome parameters. RESULTS Eight studies reporting a total of 1056 patients undergoing pancreatic cancer resection were identified. The median cut-off value for CAR was 0.05 (range 0.0003-0.54). Using multivariate analysis, all studies demonstrated that a higher CAR value was an independent and significant predictor of poor overall survival in patients undergoing pancreatic cancer resection. The estimated hazard ratio (HR) ranged from 1.4 to 3.6. Although there was a positive correlation between the reported cut-off values for CAR and HRs for overall survival, it was weak and non-significant (r = 0.36, n = 6, p = 0.480). There was significant between-study heterogeneity. CONCLUSIONS Preoperative CAR value seems to be an important prognostic score in predicting survival outcomes in patients undergoing pancreatic cancer resection. However, the current evidence does not allow the determination of an optimal cut-off value for CAR, considering the heterogeneous reporting of cut-off values by the available studies and the lack of knowledge of their sensitivity and specificity. Future research is required.

Abstract
BACKGROUND Strasberg proposed classifying subtotal cholecystectomy techniques into fenestrating (fSC) and reconstituting (rSC) subtypes. The aim of this study is to compare our outcomes of laparoscopic subtotal cholecystectomies of both subtypes against laparoscopic total cholecystectomy (TC) in difficult emergency laparoscopic cholecystectomies. METHODS Patients undergoing emergency laparoscopic cholecystectomy were identified over 2 years and all Nassar scale 3 and 4 cholecystectomies were included for analysis. RESULTS 108 fSC and 24 rSC were compared against 317 TC. Patients undergoing fSC and rSC were older and more likely to be male. fSC (128 min) and rSC (141 min) recorded longer median operative times than TC (109). Post-operative ERCP was more common after rSC (16.7%). Patients undergoing fSC (2 days) and rSC (3.5 days) had longer post-operative stays. Bile leaks were more likely in fSC (9.3%) and rSC (8.3%) compared to TC (1.9%), Long term morbidity was higher in the rSC group (12.5% vs 10%). And these were solely due to gallbladder remnant complications. CONCLUSION Laparoscopic fSC and rSC techniques are associated with a higher rate of bile leaks and rSC has more long term morbidty as compared to TC.

Abstract
Abstract
Background
Traditional single surgical quality indicators are commonly used however they are poor for assessing global outcomes for patients. Composite outcomes such as the ‘Textbook Outcome’ (TO) is a composite outcome to determine the success of the quality of the surgical process, and compare outcomes between institutions and patient groups, described by the Dutch Pancreatic Cancer Audit Group for Pancreatoduodenectomy (PD). They reported national TOs for PD of 58.3%, we compared this to TOs in a UK high volume specialist pancreas-only centre, Royal Stoke.
Methods
Patients who underwent PD from January 2017 to December 2020 were identified from our database. TO was defined as absence the following: post-operative pancreatic fistula (POPF) (grade B/C), post-pancreatectomy haemorrhage (PPH), bile leak, severe complications (Clavien Dindo grade III or more), 30-day readmission and 30-day mortality.
Results
153 patients underwent PD during the 4-year study period. The median age was 71years (range 37-85 years), and there was a slight male preponderance (54.9%, 84/153). 47% had pancreatic ductal adenocarcinoma (72/153), 17% ampullary carcinoma (26/153), 9% cholangiocarcinoma (14/153), 9% duodenal carcinoma (14/153), and benign pathology included cases with IPMN and duodenal polyps with high grade dysplasia. There was a statistically significant difference in textbook outcome in our cohort compared to the Dutch Study (70.3%, 108/153 vs 58.3%, 895/1536; p=0.003086), with components of TO shown in Figure 1.
Conclusions
TO represent composite outcome for identifying good practice, areas for shared learning and areas for improvement. PD performed in high-volume pancreas-only specialist centers appear to have better outcomes following PD than lower-volume centres. Further investigation is required to assess why outcomes are different between centres, and identify how best practice can be shared.

Abstract
Abstract
Background
During the first wave of the COVID pandemic surgical services we paralysed globally, with cancellation of an estimated 28-million operations during the first 12 weeks. Worryingly, surgical patient with COVID were reported to have unacceptably high peri-operative mortality, approaching 25%. However, there was an urgent clinical need to progress with category 1 and 2 operations, to prevent disease progression and avoidable morbidity and mortality from non-COVID pathologies. During the second and subsequent waves of the pandemic it was vital to protect patients from peri-operative COVID whilst undertaking urgent surgery safely.
Methods
Our centre developed a ring-fenced 'Green Pathway' for category 1 and 2 patients requiring surgery. Patients were treated in physically separate area of the hospital, with no interaction between COVID and non-COVID patients, healthcare staff or facilities. Patients self-isolated for 14-days prior to admission, and had pre- and peri-operative COVID RT-PCR tests. We assessed outcomes for patients immediately prior to the introduction of the Green Pathway (1/10/2020) and following implementation (31/12/2020) to assess safety. Textbook outcomes for pancreatoduodenectomy were compared to assess safety and quality. Other data suggests that UGI surgery couldn't continue in other hospitals from December 2020.
Results
There were 47 admissions to surgical HDU following category 1 and 2 upper GI operations during the study; 31 pre-pathway (PP) implementation, and 16 green pathway (GP) patients.
Median age 66-years (43-78 range) PP vs 65-years (range 42-74) GP, median ASA 3 vs 2. Median HDU length of stay (LOS) 5-days vs 7-days, and median hospital LOS 11.5-days vs 9-days for PP vs GP respectively. There were 6 cases of peri-operative COVID in PP cohort, and 1 in GP (contract following discharge). There was no mortality within either cohort. For the subgroup of patients undergoing PD: 10 patients PP, 6 patients GP, textbook outcomes were achieved in 90% vs 67% PP vs GP.
Conclusions
The implementation of the Green Pathway at our institution enabled continuation of surgery for patients with category 1 and 2 operations during the COVID pandemic with a significant reduction in peri-operative COVID infection, no mortality and no increase in length of stay. The TO rate was lower with the GP (not statistically significant), but our 4-year institution TO rate is 70.3%, comparing favourably to other studies. This pathway has enabled safe continuation of urgent surgery during the pandemic and could be a model for adoption in other centres especially if there is resurgence of COVID cases during the coming winter.

Abstract
INTRODUCTION The SARS-CoV-2 pandemic presented healthcare providers with an extreme challenge to provide cancer services. The impact upon the diagnostic and treatment capacity to treat pancreatic cancer is unclear. This study aimed to identify national variation in treatment pathways during the pandemic. METHODS A survey was distributed to all United Kingdom pancreatic specialist centres, to assess diagnostic, therapeutic and interventional services availability, and alterations in treatment pathways. A repeating methodology enabled assessment over time as the pandemic evolved. RESULTS Responses were received from all 29 centres. Over the first six weeks of the pandemic, less than a quarter of centres had normal availability of diagnostic pathways and a fifth of centres had no capacity whatsoever to undertake surgery. As the pandemic progressed services have gradually improved though most centres remain constrained to some degree. One third of centres changed their standard resectable pathway from surgery-first to neoadjuvant chemotherapy. Elderly patients, and those with COPD were less likely to be offered treatment during the pandemic. CONCLUSION The COVID-19 pandemic has affected the capacity of the NHS to provide diagnostic and staging investigations for pancreatic cancer. The impact of revised treatment pathways has yet to be realised.

Abstract
BACKGROUND Laparoscopic distal pancreatectomy (LDP) is increasingly being performed as an alternative to open surgery. Whether the implementation and corresponding learning curve of LDP have an impact on patient outcome is unknown. The aim was to investigate the temporal trends in practice across UK centres. METHODS This was a retrospective multicentre observational cohort study of LDP in 11 tertiary referral centres in the UK between 2006 and 2016. The learning curve was analysed by pooling data for the first 15 consecutive patients who had LDP and examining trends in surgical outcomes in subsequent patients. RESULTS In total, 570 patients underwent LDP, whereas 888 underwent open resection. For LDP the median duration of operation was 240 min, with 200 ml blood loss. The conversion rate was 12·1 per cent. Neuroendocrine tumours (26·7 per cent) and mucinous cystic neoplasms (19·7 per cent) were commonest indications. The proportion of LDPs increased from 24·4 per cent in 2006-2009 (P1) to 46·0 per cent in 2014-2016 (P3) (P < 0·001). LDP was increasingly performed for patients aged 70 years or more (16 per cent in P1 versus 34·4 per cent in P3; P = 0·002), pancreatic ductal adenocarcinoma (6 versus 19·1 per cent; P = 0·005) and advanced malignant tumours (27 versus 52 per cent; P = 0·016). With increasing experience, there was a trend for a decrease in blood transfusion rate (14·1 per cent for procedures 1-15 to 3·5 per cent for procedures 46-75; P = 0·008), ICU admissions (32·7 to 19·2 per cent; P = 0·021) and median duration of hospital stay (7 (i.q.r. 5-9) to 6 (4-7) days; P = 0·002). After 30 procedures, a decrease was noted in rates of both overall morbidity (57·7 versus 42·2 per cent for procedures 16-30 versus 46-75 respectively; P = 0·009) and severe morbidity (18·8 versus 9·7 per cent; P = 0·031). CONCLUSION LDP has increased as a treatment option for lesions of the distal pancreas as indications for the procedure have expanded. Perioperative outcomes improved with the number of procedures performed.

Frontline Gastroenterol 2018; 9:185-191. [PMID: 30046422 PMCID: PMC6056079 DOI: 10.1136/flgastro-2017-100839] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [What about the content of this article?

Abstract
BACKGROUND Following recommendations from the Royal College of Anaesthetists and the British Society of Gastroenterology, we report our results of propofol sedation for complex endoscopic procedures delivered by a single consultant anaesthetist over a 5-year period. METHODS A weekly session was provided in the endoscopy department for procedures that were complex or could previously not be completed successfully. Deep sedation was provided by intermittent propofol bolus doses, supplemented with fentanyl where necessary, titrated to clinical effect. Patients were usually in semiprone or lateral positions and spontaneously breathed air supplemented with nasal oxygen. Service evaluation included patient recall, endoscopist satisfaction with conditions, procedural success and airway-related adverse outcomes. RESULTS We completed 1000 procedures, 42.5% of which were endoscopic retrograde cholangiopancreatography, with the remainder comprising a diverse range of endoscopic procedures of 3-156 min duration. Procedural conditions were excellent in 79% of cases, 261 procedures were completed which had been previously abandoned, 246 patients (24.6%) had a better experience than previously and none recalled any part of their procedure. Three patients required transient bag and mask ventilation, and nasal airways were used in 12 patients, but none required tracheal intubation or vasopressor support. CONCLUSIONS These guidelines facilitated a propofol sedation service with considerable benefits for patients and endoscopists. Provision of deep propofol sedation by an anaesthetist, in patients with an unsecured airway, appears practical, effective and efficient. Small adjustments to the airway were fairly common, but the incidence of adverse events and requirement for airway instrumentation was low.

Abstract
Abstract
Background
The aims of this prospective population-based cohort study were to identify the patient and hospital characteristics associated with emergency cholecystectomy, and the influences of these in determining variations between hospitals.
Methods
Data were collected for consecutive patients undergoing cholecystectomy in acute UK and Irish hospitals between 1 March and 1 May 2014. Potential explanatory variables influencing the performance of emergency cholecystectomy were analysed by means of multilevel, multivariable logistic regression modelling using a two-level hierarchical structure with patients (level 1) nested within hospitals (level 2).
Results
Data were collected on 4744 cholecystectomies from 165 hospitals. Increasing age, lower ASA fitness grade, biliary colic, the need for further imaging (magnetic retrograde cholangiopancreatography), endoscopic interventions (endoscopic retrograde cholangiopancreatography) and admission to a non-biliary centre significantly reduced the likelihood of an emergency cholecystectomy being performed. The multilevel model was used to calculate the probability of receiving an emergency cholecystectomy for a woman aged 40 years or over with an ASA grade of I or II and a BMI of at least 25·0 kg/m2, who presented with acute cholecystitis with an ultrasound scan showing a thick-walled gallbladder and a normal common bile duct. The mean predicted probability of receiving an emergency cholecystectomy was 0·52 (95 per cent c.i. 0·45 to 0·57). The predicted probabilities ranged from 0·02 to 0·95 across the 165 hospitals, demonstrating significant variation between hospitals.
Conclusion
Patients with similar characteristics presenting to different hospitals with acute gallbladder pathology do not receive comparable care.

Abstract
Objectives To determine the incidence of bile duct reconstruction (BDR) following laparoscopic cholecystectomy (LC) and to identify associated risk factors. Background Major bile duct injury (BDI) requiring reconstruction is a serious complication of cholecystectomy. Methods All LC and attempted LC operations in England between April 2001 and March 2013 were identified. Patients with malignancy, a stone in bile duct or those who underwent bile duct exploration were excluded. This cohort of patients was followed for 1 year to identify those who underwent BDR as a surrogate marker for major BDI. Logistic regression was used to identify factors associated with the need for reconstruction. Results In total, 572,223 LC and attempted LC were performed in England between April 2001 and March 2013. Five hundred (0.09 %) of these patients underwent BDR. The risk of BDR is lower in patient that do not have acute cholecystitis [odds ratio (OR) 0.48 (95 % CI 0.30–0.76)]. The regular use of on-table cholangiography (OTC) [OR 0.69 (0.54–0.88)] and high consultant caseload >80 LC/year [OR 0.56 (0.39–0.54)] reduced the risk of BDR. Patients who underwent BDR were 10 times more likely to die within a year than those who did not require further surgery (6 vs. 0.6 %). Conclusions The rate of BDR following laparoscopic cholecystectomy in England is low (0.09 %). The study suggests that OTC should be used more widely and provides further evidence in support of the provision of LC services by specialised teams with an adequate caseload (>80).

Abstract
BARD, the BioAssay Research Database (https://bard.nih.gov/) is a public database and suite of tools developed to provide access to bioassay data produced by the NIH Molecular Libraries Program (MLP). Data from 631 MLP projects were migrated to a new structured vocabulary designed to capture bioassay data in a formalized manner, with particular emphasis placed on the description of assay protocols. New data can be submitted to BARD with a user-friendly set of tools that assist in the creation of appropriately formatted datasets and assay definitions. Data published through the BARD application program interface (API) can be accessed by researchers using web-based query tools or a desktop client. Third-party developers wishing to create new tools can use the API to produce stand-alone tools or new plug-ins that can be integrated into BARD. The entire BARD suite of tools therefore supports three classes of researcher: those who wish to publish data, those who wish to mine data for testable hypotheses, and those in the developer community who wish to build tools that leverage this carefully curated chemical biology resource.

Abstract
OBJECTIVE To examine the outcome of endoscopic retrograde cholangiopancreatography (ERCP) in the management of common bile duct (CBD) stones. DESIGN A retrospective review of 100 consecutive ERCPs performed for CBD stones. RESULTS 100 ERCPs were performed on 84 patients with a median cohort age of 77. Completion in this cohort, as defined by duct clearance, was achieved in 65% of cases. Completion rates fell rapidly after two ERCPs. 33% of the cohort had small stones <10 mm, and 67% had stones >10 mm. Size, but not number of stones, affected the completion rate and frequency of complications (16%). Presence of periampullary diverticulum did not affect completion or complication rates. MR cholangiopancreatography (MRCP) had a 90% sensitivity for detecting CBD stones compared with 56% for CT. DISCUSSION AND CONCLUSIONS ERCP remains a high-risk procedure with a significant complication rate when performed to deal with CBD stones. MRCP should be the second choice of investigation for CBD stones. This cohort had an unusually high number of larger stones at ERCP of 67% compared with other published UK cohorts of 8%, and this was reflected in the completion and complication rate.

Abstract
A 73-year-old man was admitted with symptoms of large bowel obstruction. An emergency CT scan revealed pneumobilia and large bowel obstruction at the level of the rectosigmoid due to a 4×4 cm impacted gallstone. Flexible sigmoidoscopy confirmed the diagnosis but initial attempts to drag the stone into the rectum failed. An endoscopic mechanical lithotripter was employed to repeatedly fracture the gallstone into smaller fragments, which were passed spontaneously the next day. The patient made a complete recovery avoiding the potential dangers of surgery. This case report discusses cholecystoenteric fistula and a novel minimally invasive treatment for large bowel obstruction due to gallstones.

Abstract
INTRODUCTION The aim of this study was to investigate whether definitive treatment of gallstone pancreatitis (GSP) by either cholecystectomy or endoscopic sphincterotomy in England conforms with British Society of Gastroenterology (BSG) guidelines and to validate these guidelines. METHODS Hospital Episode Statistics data were used to identify patients admitted for the first time with GSP between April 2007 and April 2008. These patients were followed until April 2009 to identify any who underwent definitive treatment or were readmitted with a further bout of GSP as an emergency. RESULTS A total of 5,454 patients were admitted with GSP between April 2007 and April 2008, of whom 1,866 (34.2%) underwent definitive treatment according to BSG guidelines, 1,471 on the index admission. Patients who underwent a cholecystectomy during the index admission were less likely to be readmitted with a further bout of GSP (1.7%) than those who underwent endoscopic sphincterotomy alone (5.3%) or those who did not undergo any form of definitive treatment (13.2%). Of those patients who did not undergo definitive treatment before discharge, 2,239 received definitive treatment following discharge but only 395 (17.6%) of these had this within 2 weeks. Of the 505 patients who did not undergo definitive treatment on the index admission and who were readmitted as an emergency with GSP, 154 (30.5%) were admitted during the 2 weeks immediately following discharge. CONCLUSIONS Following an attack of mild GSP, cholecystectomy should be offered to all patients prior to discharge. If patients are not fit for surgery, an endoscopic sphincterotomy should be performed as definitive treatment.

Abstract
INTRODUCTION Despite increasing evidence of the benefits and safety of early laparoscopic cholecystectomy (LC) in acute gallstone disease, it is not widely practised in England. The Royal College of Surgeons of England support the separation of emergency and elective surgical care. The aim of this prospective study was to examine the impact of the implementation of 'Surgeon of the Week (SoW)' model on the number of early LCs performed and the efficiency of the emergency theatre activity in our hospital. This study also looked into its implications on specialist registrar training for early LC, and the financial impact to the hospital. PATIENTS AND METHODS Between January 2007 and May 2008, demographic data, admission and discharge dates, complications, conversions to an open operation and deaths were collected for all patients who underwent early laparoscopic cholecystectomies. For ease of comparison, patients were divided into Group A representing before introduction of SoW (1 January 2007 to 30 August 2007) and Group B representing after introduction of SoW (1 October 2007 to 31 May 2008). The total numbers of operations performed in the emergency theatre list in the two groups were also calculated. RESULTS A total of 1361 emergency operations were performed on the emergency theatre list in Group A, of which 951 were general surgical procedures. In Group B, the numbers of emergency procedures were 1537, of which 1138 were general surgical operations. There was a significant increase in the number of general surgical operations after introduction of SoW (P = 0.013). Before introduction of the SoW rota, 45 early LCs were performed. This increased to 118 after SoW which was significant (P < 0.001). In Group A, the number of early LCs performed by surgical trainees was 10 (22%). In Group B, the number of LCs performed by surgical trainees was 35 (30%; not significant). CONCLUSIONS This study has demonstrated an increase in the efficiency of the emergency theatre with an increase in the number of early LCs on their index admission without extra morbidity following implementation of the SOW model in our hospital. We recommend the introduction of a suitable emergency surgical consultant on-call model separating emergency and elective surgical care depending on local circumstances. This can lead to significant cost savings and reduce re-admissions with gallstone-related complications.

Abstract
BACKGROUND The place of laparoscopic repair of perforated peptic ulcer followed by peritoneal toilet has been established, although it is not routinely practiced. This prospective study compared laparoscopic and open repair of perforated peptic ulcer disease. We evaluated whether the early results from laparoscopic repair resulted in improved patient outcome compared with conventional open repair. METHODS All patients who underwent repair of perforated peptic ulcer disease during a 12-month period in our unit were included in the study. The primary end points that were evaluated were total operative time, nasogastric tube utilisation, intravenous fluid requirement, total time of urinary catheter and abdominal drainage usage, time taken to return to normal diet, intravenous/intramuscular opiate use, time to full mobilization, and total in-patient hospital stay. RESULTS Thirty-three patients underwent surgical repair of perforated peptic ulcer disease (19 laparoscopic repairs and 14 open repairs; mean age, 54.2 (range, 32-82) years). There was no increase in total operative time in patients who had undergone laparoscopic repair (mean: 61 minutes laparoscopic versus 57 minutes open). There was significantly less requirement for intravenous/intramuscular opiate analgesia in patients who had undergone laparoscopic repair (mean time to oral analgesia: 1.2 days laparoscopic versus 3.8 days open). In addition there was a significant decrease in the time that the nasogastric tube (mean: 2.1 days laparoscopic versus 3.1 days open), urinary catheter (mean: 2.3 days laparoscopic versus 3.7 days open) and abdominal drain (mean: 2.2 days laparoscopic versus 3.8 days open) were required during the postoperative period. Patients who had undergone laparoscopic repair required less intravenous fluids (mean: 1.4 days laparoscopic versus 3.1 days open) and returned to normal diet (mean: 2.3 days laparoscopic versus 4.8 days open) and full mobilization significantly earlier than those who had undergone open repair (mean: 2.3 days laparoscopic versus 3.3 days open). In addition, patients who had undergone laparoscopic repair required a shorter in-patient hospital stay (mean: 3.1 days laparoscopic versus 4.3 days open). CONCLUSIONS Laparoscopic repair is a viable and safe surgical option for patients with perforated peptic ulcer disease and should be considered for all patients, providing that the necessary expertise is available.

Abstract
Mycobacterium avium subsp. paratuberculosis is a robust and phenotypically versatile pathogen which causes chronic inflammation of the intestine in many species, including primates. M. avium subsp. paratuberculosis infection is widespread in domestic livestock and is present in retail pasteurized cows' milk in the United Kingdom and, potentially, elsewhere. Water supplies are also at risk. The involvement of M. avium subsp. paratuberculosis in Crohn's disease (CD) in humans has been uncertain because of the substantial difficulties in detecting this pathogen. In its Ziehl-Neelsen staining-negative form, M. avium subsp. paratuberculosis is highly resistant to chemical and enzymatic lysis. The present study describes the development of optimized sample processing and DNA extraction procedures with fresh human intestinal mucosal biopsy specimens which ensure access to M. avium subsp. paratuberculosis DNA and maximize detection of these low-abundance pathogens. Also described are two nested PCR methodologies targeted at IS900, designated IS900[L/AV] and IS900[TJ1-4], which are uniquely specific for IS900. Detection of M. avium subsp. paratuberculosis in mucosal biopsy specimens was also evaluated by using mycobacterial growth indicator tube (MGIT) cultures (Becton Dickinson). IS900[L/AV] PCR detected M. avium subsp. paratuberculosis in 34 of 37 (92%) patients with CD and in 9 of 34 (26%) controls without CD (noninflammatory bowel disease [nIBD] controls) (P = 0.0002; odds ratio = 3.47). M. avium subsp. paratuberculosis was detected by IS900[L/AV] PCR in MGIT cultures after 14 to 88 weeks of incubation in 14 of 33 (42%) CD patients and 3 of 33 (9%) nIBD controls (P = 0.0019; odds ratio = 4.66). Nine of 15 (60%) MGIT cultures of specimens from CD patients incubated for more than 38 weeks were positive for M. avium subsp. paratuberculosis. In each case the identity of IS900 from M. avium subsp. paratuberculosis was verified by amplicon sequencing. The rate of detection of M. avium subsp. paratuberculosis in individuals with CD is highly significant and implicates this chronic enteric pathogen in disease causation.

Abstract
We report the experimental dynamics of a new two-dimensional (2D) fluid phenomenon that occurs when an intense, pointlike vortex is placed within a diffuse, circular vortex. Our observations, made using strongly magnetized electron columns to model the 2D fluid, support the analysis performed by Jin and Dubin.

Abstract
The concept of dual opposite injection in capillary electrophoresis (DOI-CE) for the simultaneous separation, under conditions of suppressed electroosmotic flow, of anionic and cationic compounds with no bias in resolution and analysis time, is extended to a higher pH range in a zone electrophoresis mode (DOI-CZE). A new DOI-CE separation mode based on electrokinetic chromatography is also introduced (DOI-EKC). Whereas conventional CZE and DOI-CZE are limited to the separation of charged compounds with different electrophoretic mobilities, DOI-EKC is shown to be capable of separating compounds with the same or similar electrophoretic mobilities. In contrast to conventional EKC with charged pseudostationary phases that often interact too strongly with analytes of opposite charge, the neutral pseudostationary phases appropriate for DOI-EKC are simultaneously compatible with anionic and cationic compounds. This work describes two buffer additives that dynamically suppress electroosmotic flow (EOF) at a higher pH (6.5) than in a previous study (4.4), thus allowing DOI-CZE of several pharmaceutical bases and weakly acidic positional isomers. Several DOI-EKC systems based on nonionic (10 lauryl ether, Brij 35) or zwitterionic (SB-12, CAS U) micelles, or nonionic vesicles (Brij 30) are examined using a six-component test mixture that is difficult to separate by CZE or DOI-CZE. The effect of electromigration dispersion on peak shape and efficiency, and the effect of surfactant concentration on retention, selectivity, and efficiency are described.

Abstract
Pulmonary function testing was used in MRFIT to monitor the presence of airways disease and to assess changes in pulmonary function over time. The pulmonary function indices that were measured were FEV1, FVC, and MMEF, (FEF25-75). Quality control of technician training, equipment maintenance, data collection, and data measurement were essential to ensure that results, over time and from various clinics, could be compared. Based on the MRFIT experience, it is strongly recommended that centralized training in testing techniques and spirometer maintenance take place before a clinical trial begins, and periodically throughout a trial. Such training, combined with quality control follow-up, should prevent the loss of data due to inadequate spirometer maintenance and invalid testing procedures.
