Population-based observational study of acute pancreatitis in southern England.

INTRODUCTION: Acute pancreatitis is a common surgical emergency. Identifying variations in presentation, incidence and management may assist standardisation and optimisation of care. The objective of the study was to document the current incidence management and outcomes of acute pancreatitis against international guidelines, and to assess temporal trends over the past 20 years. METHODS: A prospective four-month audit of patients with acute pancreatitis was performed across the Wessex region. The Atlanta 2012 classifications were used to define cases, severity and complications. Outcomes were recorded using validated systems and correlated against guideline standards. Case ascertainment was validated with clinical coding and hospital episode statistics data. RESULTS: A total of 283 patient admissions with acute pancreatitis were identified. Aetiology included 153 gallstones (54%), 65 idiopathic (23%), 29 alcohol (10%), 9 endoscopic retrograde cholangiopancreatography (3%), 6 drug related (2%), 5 tumour (2%) and 16 other (6%). Compliance with guidelines had improved compared with our previous regional audit. Results were 6.5% mortality, 74% severity stratification, 23% idiopathic cases, 65% definitive treatment of gallstones within 2 weeks, 39% computed tomography within 6-10 days of severe pancreatitis presentation and 82% severe pancreatitis critical care admission. The Atlanta 2012 severity criteria significantly correlated with critical care stay, length of stay, development of complications and mortality (2% vs 6% vs 36%, P < 0.0001). CONCLUSIONS: The incidence of acute pancreatitis in southern England has risen substantially. The Atlanta 2012 classification identifies patients with severe pancreatitis who have a high risk of fatal outcome. Acute pancreatitis management is seen to have evolved in keeping with new evidence and updated clinical guidelines.

What is the role of enhanced recovery after surgery in children? A scoping review.

PURPOSE: Enhanced recovery after surgery (ERAS) pathways are standard practice in adult specialties resulting in improved outcomes. It is unclear whether ERAS principles are applicable to Paediatric Surgery. We performed a scoping review to identify the extent to which ERAS has been used in Paediatric Surgery, the nature of interventions, and outcomes. METHODS: Pubmed, Cochrane library, Google Scholar, and Embase were searched using the terms enhanced recovery, post-operative protocol/pathway, fast track surgery, and paediatric surgery. Studies were excluded if they did not include abdominal/thoracic/urological procedures in children. RESULTS: Nine studies were identified (2003-2014; total 1269 patients): three case control studies, one retrospective review and five prospective implementations, no RCTs. Interventional elements identified were post-operative feeding, mobilisation protocols, morphine-sparing analgesia, reduced use of nasogastric tubes and urinary catheters. Outcomes reported included post-operative length of stay (LOS), time to oral feeding and stooling, complications, and parent satisfaction. Fast-track programmes significantly reduced LOS in 6/7 studies, time to oral feeding in 3/3 studies, and time to stooling in 2/3 studies. CONCLUSION: The use of ERAS pathways in Paediatric surgery appears very limited but such pathways may have benefits in children. Prospective studies should evaluate interventions used in adult ERAS on appropriate outcomes in the paediatric setting.

A study evaluating the bidirectional relationship between inflammatory bowel disease and self-reported non-celiac gluten sensitivity.

BACKGROUND: Non-celiac gluten sensitivity and the associated use of a gluten-free diet (GFD) are perceived to belong to the spectrum of irritable bowel syndrome (IBS). However, recent reports suggest substantial use of a GFD in inflammatory bowel disease (IBD). We assessed the bidirectional relationship between IBD and self-reported non-celiac gluten sensitivity (SR-NCGS). METHODS: A cross-sectional questionnaire screened for SR-NCGS and the use of a GFD in 4 groups: ulcerative colitis (n = 75), Crohn's disease (n = 70), IBS (n = 59), and dyspeptic controls (n = 109). We also assessed diagnostic outcomes for IBD in 200 patients presenting with SR-NCGS. RESULTS: The prevalence of SR-NCGS was 42.4% (n = 25/59) for IBS, followed by 27.6% (n = 40/145) for IBD, and least among dyspeptic controls at 17.4% (n = 19/109); P = 0.015. The current use of a GFD was 11.9% (n = 7/59) for IBS, 6.2% (n = 9/145) for IBD, and 0.9% (1/109) for dyspeptic controls; P = 0.02. No differences were established between ulcerative colitis and Crohn's disease. However, Crohn's disease patients with SR-NCGS were significantly more likely to have stricturing disease (40.9% versus 18.9%, P = 0.046), and higher mean Crohn's Disease Activity Index score (228.1 versus 133.3, P = 0.002), than those without SR-NCGS. Analysis of 200 cases presenting with SR-NCGS suggested that 98.5% (n = 197) could be dietary-related IBS. However, 1.5% (n = 3) were found to have IBD; such patients had associated alarm symptoms, and/or abnormal blood parameters, prompting colonic investigations. CONCLUSIONS: SR-NCGS is not only exclusive to IBS but also associated with IBD, where its presence may be reflecting severe or stricturing disease. Randomized studies are required to further delineate the nature of this relationship and clarify whether a GFD is a valuable dietetic intervention in selected IBD patients.

Evaluation of community-based trichiasis surgery in Northwest Ethiopia.

BACKGROUND: Surgery to correct trachomatous trichiasis (TT) is recommended to prevent blindness caused by trachoma. This study evaluated the outcomes of community-based trichiasis surgery with absorbable sutures, conducted in Amhara Regional State, Ethiopia. METHODS: A simple random sample of 431 patients was selected from surgical campaign records of which 363 (84.2%) were traced and enrolled into the study. Participants were interviewed and examined for trichiasis recurrence, complications of TT surgery and corneal opacity. Multilevel logistic regression models were used to explore the associations between trichiasis recurrence, corneal opacity and explanatory variables at the eye level. RESULTS: The prevalence of trichiasis recurrence was 9.4% (95% Confidence Interval [CI] 6.6-12.8) and corneal opacity was found in 14.3% (95% CI 10.9-18.3) of the study participants. The proportion of participants with complications of TT surgery was: granuloma 0.6% (95% CI 0.1-2.0); lid closure defects 5.5% (95% CI 3.4-8.4) and lid notching 16.8% (95% CI 13.1-21.1). No factors were identified for trichiasis recurrence. Corneal opacity was associated with increased age (Ptrend=0.001), more than 12 months post surgery (OR=2.7; 95%CI 1.3-5.6), trichiasis surgery complications (OR=2.9; 95%CI 1.4-5.9) and trichiasis recurrence (OR=2.5; 95%CI 1.0-6.3). CONCLUSION: Prevalence of recurrent trichiasis and granuloma were lower than expected but higher for lid closure defects and lid notching. The majority of the participants reported satisfaction with the trichiasis surgery they had undergone. The findings suggest that recurrence of trichiasis impacts on the patients' risk of developing corneal opacity but longitudinal studies are required to confirm this.

Pre-operative chemoradiation for non-metastatic locally advanced rectal cancer.

BACKGROUND: This review sets out to assess the efficacy of pre-operative chemoradiation when compared to radiotherapy alone before surgery in the treatment of advanced non metastatic rectal surgery. OBJECTIVES: To determine the efficacy of pre-operative chemoradiation (CRT) compared with radiation (RT) alone, in locally advanced rectal cancer with respect to overall survival, local recurrence and 30 day mortality, sphincter preservation and toxicity of treatment (both acute and late). SEARCH METHODS: In September 2011, we searched clinical trial registers, the Cochrane Central Register of Controlled Trials, Web of Science, EMBASE and MEDLINE and reviewed reference lists. Further hand searches were conducted of relevant journal proceedings. No language constraints were applied.The following search terms were used: colorectal, rectal, rectum, cancer, carcinoma, tumour, radiotherapy, chemotherapy, chemoradiotherapy, chemoradiation, 5-Fluorouracil, 5-FU, neo-adjuvant, preoperative, surgery, anterior resection, abdominoperineal resection, total mesorectal excision. SELECTION CRITERIA: Male and female patients aged over 18 years undergoing preoperative chemoradiation or radiotherapy followed by surgery for locally advanced non-metastatic rectal cancer. There was no upper age limit for participants. Locally advanced non-metastatic cancer was defined as stage 3 rectal tumours. These are tumours of any T stage with nodal involvement, without evidence of distant metastases. DATA COLLECTION AND ANALYSIS: Primary outcome parameters included overall survival and local recurrence rate. Secondary outcome parameters included 30 day mortality, sphincter preservation, pathological response of tumour, acute and late toxicity of treatment. The outcome parameters were summarized using the odds ratio and 95% confidence intervals (CI). MAIN RESULTS: There were 6 randomised controlled trials eligible for inclusion. A reduction in local recurrence was seen in the CRT group in comparison to the RT group (OR 0.56, 95% CI 0.42-0.75, P<0.0001). The results for overall survival were (OR=1.01 95%CI 0.85-1.20, P=0.88).The 30 day mortality was the same for both groups, CRT vs RT (OR 1.73, 95% CI 0.88-3.38). Sphincter preservation (stoma rate) was also similar for the two interventions (OR 1.02, 95% CI 0.85-1.21, P=0.64). An increase in acute grade 3/4 treatment related toxicity was seen in the CRT group versus the RT group (OR 3.96, 95% CI 3.03, 5.17, P<0.00001), although this result did display heterogeneity P=0.0005. Late toxicity events were similar between the two groups (OR 0.88, 95% CI 0.50, 1.54, P=0.65). AUTHORS' CONCLUSIONS: RT was compared to the more intensive CRT in the treatment of T3-4, node positive (locally advanced) rectal cancer. While there was no difference in overall survival between RT and CRT, CRT was associated with less local recurrence.
