ABSTRACT
INTRODUCTION: Appropriately selecting patients with chronic pancreatitis associated with pancreas divisum (PD) for endoscopic retrograde cholangiopancreatography (ERCP)-based therapy versus surgery remains difficult. The objective of this study was to identify factors that predict success or failure of ERCP for treatment of chronic pancreatitis in PD. METHODS: Patients undergoing ERCP for a diagnosis of PD and pancreatitis between 2008 and 2016 were identified and grouped according to whether they required one or two ERCPs or three or more ERCPs. Groups were compared along demographic, diagnostic, laboratory, ERCP-related, and outcome variables. RESULTS: Patients requiring 1-2 ERCPs were less likely to have back pain on initial presentation (4 vs. 24%, p = 0.02) and less likely to have a dilated bile duct on imaging prior to their first ERCP (8 vs. 30%, p = 0.04) than those requiring 3+ ERCPs. Patients requiring 1-2 ERCPs were also less likely to eventually require operative intervention for treatment of their chronic pancreatitis than those requiring 3+ ERCPs (24 vs. 44%, p = 0.047). On multivariable analysis, a dilated bile duct (odds ratio (OR) = 6.0, 95% confidence interval (CI) = 1.01-36.0, p = 0.048) was independently associated with requiring 3+ ERCPs. Back pain (OR = 6.3, 95% CI = 0.73-54.2, p = 0.09) trended toward but did not reach statistical significance for being independently associated with requiring 3+ ERCPs. CONCLUSIONS: The success of endoscopic treatment of chronic pancreatitis in patients with PD is dependent on proper patient selection. Patients with a dilated bile duct and back pain upon presentation may not respond well to endoscopic treatment alone and are more likely to eventually require operative intervention. Consideration should be given to early operative intervention in these patients.

INTRODUCTION: Over the last 5 years, the American Association for the Surgery of Trauma has developed grading scales for emergency general surgery (EGS) diseases. In a previous validation study using diverticulitis, the grading scales were predictive of complications and length of stay. As EGS encompasses diverse diseases, the purpose of this study was to validate the grading scale concept against a different disease process with a higher associated mortality. We hypothesized that the grading scale would be predictive of complications, length of stay, and mortality in skin and soft-tissue infections (STIs). METHODS: This multi-institutional trial encompassed 12 centers. Data collected included demographic variables, disease characteristics, and outcomes such as mortality, overall complications, and hospital and ICU length of stay. The EGS scale for STI was used to grade each infection and two surgeons graded each case to evaluate inter-rater reliability. RESULTS: 1170 patients were included in this study. Inter-rater reliability was moderate (kappa coefficient 0.472-0.642, with 64-76% agreement). Higher grades (IV and V) corresponded to significantly higher Laboratory Risk Indicator for Necrotizing Fasciitis scores when compared with lower EGS grades. Patients with grade IV and V STI had significantly increased odds of all complications, as well as ICU and overall length of stay. These associations remained significant in logistic regression controlling for age, gender, comorbidities, mental status, and hospital-level volume. Grade V disease was significantly associated with mortality as well. CONCLUSION: This validation effort demonstrates that grade IV and V STI are significantly predictive of complications, hospital length of stay, and mortality. Though predictive ability does not improve linearly with STI grade, this is consistent with the clinical disease process in which lower grades represent cellulitis and abscess and higher grades are invasive infections. This second validation study confirms the EGS grading scale as predictive, and easily used, in disparate disease processes. LEVEL OF EVIDENCE: Prognostic/Epidemiologic retrospective multicenter trial, level III.

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) with stent placement is used for the management of many pancreaticobiliary disorders. It is generally safe with a few short-term complications. The risk factors for the development of post-ERCP cholangitis due to stent occlusion have not been previously described. This study identified such risk factors among patients undergoing ERCP and stent placement for pancreatic or biliary obstruction. METHODS: 3648 ERCPs performed at the University of Louisville from 2008 to 2016 were reviewed. Data including patient demographics, diagnostic, laboratory, and ERCP related data were included. Patients were classified as having post-ERCP cholangitis if they developed jaundice, fever, right upper quadrant abdominal pain, and confirmatory findings of stent occlusion and/or purulent drainage at the time of repeat ERCP. These patients were compared to those who did not develop post-ERCP cholangitis using univariate and multivariate analyses. RESULTS: A total of 431 patients met inclusion criteria. Of these, 57 (13.2%) developed post-ERCP cholangitis. The average age of patients was 57 years with 57% women and 43% men. On univariate analysis, patients developing post-ERCP cholangitis were more likely to be of increased age, have higher white blood cell count (WBC), total bilirubin (TBili), AST, ALT, and alkaline phosphatase (AlkPhos), and a decreased serum albumin level. Risk factors for post-ERCP cholangitis due to stent occlusion identified on multivariate analysis include: a diagnosis of cancer, the placement of multiple biliary stents at index ERCP, and low serum albumin level. CONCLUSIONS: The development of post-ERCP cholangitis due to stent occlusion is strongly associated with the presence of malignancy, the placement of multiple biliary stents, and low serum albumin. A decreased threshold to monitor for stent occlusion, including routine liver function tests and prophylactic stent removal or exchange, should be employed in patients with these characteristics.

Adrenocortical carcinoma (ACC) is rare within the adult population. Ectopic ACC proves even rarer. This variant is formed by cortical fragments arrested during embryologic migration. ACC is also known to be associated with several genetic syndromes and has recently been linked to Lynch syndrome in 3% of cases. We present the case of a 68-year-old male with a confirmed diagnosis of Lynch syndrome secondary to a germline MSH2 mismatch-repair gene-mutation who presented with 2 months history of non-specific abdominal pain. After imaging work-up, the patient was found to have a right upper quadrant, retroperitoneal mass. Biochemical tests were without any evidence of a hormonally active process. Fine needle aspiration of the mass revealed a poorly differentiated carcinoma of unknown etiology. The lesion was resected and found to be consistent with ectopic ACC with an associated MSH2 mutation.

BACKGROUND: To date, no studies have evaluated the correlation between number of endoscopic ultrasound (EUS) criteria met for chronic pancreatitis (CP) and symptom severity over the course of the disease. This study assessed the relationship between number of EUS-based diagnostic criteria for CP and CP severity over time. METHODS: A University of Louisville database was queried for patients undergoing EUS due to concern for chronic pancreatitis between 2005 and 2016. Patients were grouped based on EUS criteria met for CP and groups were compared along outcome and procedural variables. RESULTS: Of a total of 243 patients, 24, 129, and 90 patients met 1-3, 4-5, and ≥6 EUS diagnostic criteria, respectively. Median follow-up time was 33 months. Along all follow-up parameters, number of diagnostic criteria was positively correlated with an increased percentage of patients requiring operative intervention for chronic pancreatitis on univariate and multivariate analysis. CONCLUSIONS: In addition to the role of EUS criteria in establishing the diagnostic severity of patients with symptomatic chronic pancreatitis, the number of EUS-based criteria may help predict patients who will eventually require operative intervention and thus prompt referral to a pancreatobiliary surgeon earlier in the course of a patient's disease.

BACKGROUND: The diagnostic and therapeutic roles for endoscopic intervention are expanding. To continue emphasis on endoscopy in surgical training, The Society of American Gastrointestinal and Endoscopic Surgeons has developed the Fundamentals of Endoscopic Surgery (FES) course to standardize and assess endoscopy training. However, little demographic information exists about the current practice of endoscopy by general surgeons and how to best integrate endoscopic skills into surgical training. METHODS: A survey to collect data regarding the current practice patterns of endoscopy was sent to surgeons with a valid email address in the American Medical Association masterfile. Information regarding the type of training (academic vs. community general surgery residency) and current practice environment (academic medical center vs. community hospital) was collected. The respondents' current practice volume of upper endoscopy and colonoscopy over the prior year was stratified into three groups: rare (<1 per month), moderate (1-10 per month), and frequent (>10 per month). Pearson's Chi-squared test was used to analyze the data. RESULTS: The survey was sent to 9902 general surgeons. There were 767 who provided answers regarding their current practice of endoscopy. Mean time in practice was 18 ± 10 years, 87 % were male, and 83 % practiced in a metropolitan area. Respondents who trained at academic general surgery programs were less likely than those at community programs to frequently perform colonoscopy (17.3 vs. 27.9 %, p < 0.05) and upper endoscopy (11.8 vs. 17.1 %, p < 0.05). Those who currently practice in academic medical centers were also less likely to be frequent performers of colonoscopy (5.6 vs. 24.7 %, p < 0.05) and upper endoscopy (9.8 vs. 14.8 %, p < 0.05) than those who practice at community hospitals. CONCLUSIONS: The type of residency training and current practice setting of general surgeons has a significant influence on the volume of endoscopic procedures performed. This study identifies areas where more emphasis on endoscopic skills training is needed, such as FES.

BACKGROUND: The ABO blood subgroup A2 expresses lower levels of A antigen on the cell surface and is less immunogenic toward anti-A immunoglobulin present in blood type O or B recipients. Previous studies have shown successful kidney transplantation from A2 donors into O or B recipients with low pre-transplant anti-A titers. Previous studies suggest good results with recipient IgG titers <1:8. Few studies have specifically evaluated the importance of anti-A1 IgM titers on early outcomes following A2 to O or B kidney transplantation. METHODS: We performed a single center, retrospective review of all A2 to O living donor kidney transplants. All recipients had pre-transplant anti-A IgG titers <1:8. IgM titers were measured in all recipients and were reported but not used to determine eligibility for transplant. RESULTS: From 2001 to 2013, we performed seven consecutive A2 to O living donor kidney transplants. Early allograft dysfunction, acute rejection or thrombotic microangiopathy, occurred in four patients and were associated with high IgM titers despite low IgG titers. CONCLUSIONS: Our data show a high incidence of early acute rejection or thrombotic microangiopathy in A2 to O kidney transplants with high recipient anti-A IgM titers despite low IgG titers. Steps to lower anti-IgM pre-transplant may reduce the risk of early allograft dysfunction in A2 to O or B kidney transplants. Attention should be paid to IgM titers in establishing individual center selection criteria for A2 to B kidney transplants under the new UNOS kidney allocation system.
