Introduction: Severe abdominal pain is a cardinal symptom of chronic pancreatitis (CP) associated with a high economic and societal burden. In other chronic pain conditions, cognitive-behavioral therapy (CBT) has demonstrated efficacy in improving patient outcomes (e.g., pain-related disability and depression). However, CBT has not yet been evaluated in adult patients with painful CP. We aimed to (i) evaluate the feasibility and acceptability of an adapted Internet CBT program for CP and (ii) generate pilot data regarding the effects of treatment on patient pain outcomes., Methods: Thirty adults (mean age = 49.8 years, SD = 12.5; 80% women) with suspected or definite CP were randomized to Internet CBT (Pancreatitis Pain Course) versus control. The Pancreatitis Pain Course has 5 CBT lessons (e.g., thought challenging, relaxation, and activity pacing) delivered over 8 weeks. Pain interference, pain intensity, and quality of life were assessed at pretreatment, posttreatment, and the 3-month follow-up. Qualitative interviews were conducted at posttreatment with a subset of participants., Results: Eighty percent of participants rated the program as highly acceptable; 64.3% completed all 5 lessons. Qualitative data revealed positive perceptions of program features, relevancy, and skills. Patients randomized to Internet CBT demonstrated moderate to large effects in reducing pain intensity and pain interference from baseline to 3 months. The proportion of treatment responders (>30% improvement) was significantly greater in the Internet-CBT group than in the control group (50% vs 13%, Fisher exact t test P = 0.04)., Discussion: In this first trial of CBT pain self-management in CP, feasibility, acceptability, and preliminary efficacy for reducing pain and disability were demonstrated. Future definitive trials of CBT are needed., (Copyright © 2021 The Author(s). Published by Wolters Kluwer Health, Inc. on behalf of The American College of Gastroenterology.)

Background & Aims: IgG4-related disease (IgG4-RD), a multi-organ fibroinflammatory syndrome, typically responds to steroids. However, some cases are steroid resistant, and pancreaticobiliary IgG4-RD commonly relapses after steroid withdrawal. Rituximab induces remission of IgG4-RD, but the need for and safety of maintenance rituximab treatment are unknown. We compared outcomes of patients with pancreaticobiliary IgG4-RD treated with or without maintenance rituximab therapy., Methods: We performed a retrospective study of patients with pancreaticobiliary IgG4-RD treated with rituximab at the Mayo Clinic in Rochester, Minnesota, from January 2005 through December 2015. The cohort was divided into patients who received only rituximab induction therapy (group 1, n = 14) and patients who received rituximab induction followed by maintenance therapy (group 2, n = 29). We collected data on recurrence of IgG4-RD symptoms and findings, as well as information on evaluations, treatment, and adverse events., Results: Median follow-up times were similar between group 1 (34 mo) and group 2 (27 mo) (P = .99). Thirty-seven patients (86%) were in steroid-free remission 6 months after rituximab initiation. A higher proportion of patients in group 1 had disease relapse (3-year event rate, 45%) than in group 2 (3-year event rate, 11%) (P = .034). Younger age, higher IgG4 responder index score after induction therapy, and increased serum levels of alkaline phosphatase at baseline or after rituximab induction were associated with relapse. Infections developed in 6 of 43 patients, all in group 2 (P = .067 vs group 1); all but 1 occurred during maintenance therapy., Conclusions: In a retrospective study of patients with pancreaticobiliary IgG4-RD, we found rituximab maintenance therapy prolongs remission. Relapses are uncommon among patients receiving maintenance therapy, but maintenance therapy may increase risk of infection. Patients with factors that predict relapse could be candidates for rituximab maintenance therapy., (Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Background & Aims: A diagnosis of pancreatic cancer in a first-degree relative increases an individuals' risk of this cancer. However, it is not clear whether this cancer risk increases in individuals with pancreatic cystic lesions who have a first-degree relative with pancreatic cancer. The Fukuoka criteria are used to estimate risk of pancreatic cancer for patients with pancreatic cystic lesions: individuals with cysts with high risk or worrisome features (Fukuoka positive) have a higher risk of pancreatic cancer than individuals without these features (Fukuoka negative). We aimed to compare the risk of pancreatic cancer and surgery based on presence or absence of pancreatic cystic lesions and a first-degree relative with pancreatic cancer., Methods: We performed a retrospective study of patients seen at the Mayo Clinic in Rochester, Minnesota, from January 1, 2000, through December 31, 2012. We identified individuals with: pancreatic cystic lesions and first-degree relative with pancreatic cancer (group 1, n = 269), individuals with pancreatic cystic lesions but no first-degree relative with pancreatic cancer (group 2, n = 1195), and individuals without pancreatic cystic lesions but with a first-degree relative with pancreatic cancer (group 3, n = 720). We compared, among groups, as well among patients with cysts classified according to Fukuoka criteria, proportions of individuals who developed pancreatic cancer or underwent pancreatic surgery within a 5-year period., Results: A significantly higher proportion of individuals in group 1 developed pancreatic cancer during the 5-year period than in group 3 (6.64% vs 1.69%; P = .03); there was no significant difference between the percentage of individuals in group 1 vs group 2 who developed pancreatic cancer (6.64% vs 4.05%; P = .41). There was no significant difference in pancreatic cancer development among individuals with Fukuoka-positive cysts with vs without a family history of pancreatic cancer (P = .39). There was no significant difference in the proportion of patients in group 1 vs group 2 who underwent pancreatic surgery for their pancreatic cyst over the 5-year period (14.37% vs 11.80%; P = .59). Among patients with Fukuoka-negative cysts, a significantly higher proportion underwent surgery in group 1 than in group 2 (10.90% vs 5.90%; P = .03). However, among patients with Fukuoka-positive cysts, there was no difference in proportions of patients who underwent surgery between groups 1 and 2 (P = .66)., Conclusions: In a retrospective study of patients with pancreatic cysts and/or cancer, we found that a family history of pancreatic cancer does not affect 5-year risk of pancreatic cancer in patients with pancreatic cystic lesions. Despite this, among patients with Fukuoka-negative cysts, a higher proportion of those with a family history of pancreatic cancer undergo surgery than patients without family history of pancreatic cancer., (Copyright © 2018 AGA Institute.

Background: New-onset diabetes mellitus after a pancreaticoduodenectomy (PD) remains poorly defined. The aim of this study was to define the incidence and predictive factors of immediate post-resection diabetes mellitus (iPRDM)., Methods: Retrospective review of patients undergoing PD from January 2004 through to July 2010. Immediate post-resection diabetes mellitus was defined as diabetes requiring pharmacological treatment within 30 days post-operatively. Logistic regression was conducted to identify factors predictive of iPRDM., Results: Of 778 patients undergoing PD, 214 were excluded owing to pre-operative diabetes (n= 192), declined research authorization (n= 14) or death prior to hospital discharge (n= 8); the remaining 564 patients comprised the study population. iPRDM occurred in 22 patients (4%) who were more likely to be male, have pre-operative glucose intolerance, or an increased creatinine, body mass index (BMI), pre-operative glucose, operative time, tumour size or specimen length compared with patients without iPRDM (P < 0.05). On multivariate analysis, pre-operative impaired glucose intolerance (P < 0.001), pre-operative glucose ≥ 126 (P < 0.001) and specimen length (P= 0.002) were independent predictors of iPRDM. A predictive model using these three factors demonstrated a c-index of 0.842., Discussion: New-onset, post-resection diabetes occurs in 4% of patients undergoing PD. Factors predictive of iPRDM include pre-operative glucose intolerance, elevated pre-operative glucose and increased specimen length. These data are important for patient education and predicting outcomes after PD., (Published 2012. This article is a U.S. Government work and is in the public domain in the USA.)

Objective: We described the entity moderately severe acute pancreatitis (MSAP), characterized by local complications (LCs) without organ failure (OF). The aim of this study was to validate MSAP., Methods: We classified a prospectively collected cohort of 137 acute pancreatitis patients admitted to Mayo Clinic Hospitals into (a) severe acute pancreatitis (SAP; n = 15), presence of OF with/without LCs; (b) MSAP (n = 27), presence of LCs without OF; and (c) mild acute pancreatitis (MAP; n = 95), no OF and LCs. Primary outcomes were need for intensive care unit (ICU) care, total ICU days, total hospital stay, need for interventions, and death., Results: Scores in the Acute Physiology and Chronic Health Evaluation II during admission were significantly different among the 3 groups (MAP vs MSAP, P = 0.02; MSAP vs SAP, P = 0.001); scores in the systemic inflammatory response syndrome during admission were similar between MAP and MSAP. Compared with patients with MAP, patients with MSAP had a significantly longer hospital stay (4 [3.0-7.0] vs 6 [4.0-18.0] days). Compared with those with SAP, a significantly smaller proportion of patients with MSAP required ICU care (12% vs 80%); total hospital stay and need for interventions were similar (6 [4.0-18.0] vs 21 [11.8-27] days and 44% vs 33%, respectively). None of the MSAP patients died compared with 40% from the SAP group., Conclusions: We have validated MSAP as an exclusive entity.

Background & Aims: Colorectal cancer (CRC) screening has been advocated increasingly during the past 2 decades, but there is little direct evidence that it has affected cancer incidence or presentation at the population level. This study assessed concurrent trends in CRC incidence, presentation, survival, mortality, and polypectomies in Olmsted County, Minnesota., Methods: Longitudinal observational study was conducted of all Olmsted County residents with colorectal adenocarcinoma first diagnosed in 1980-1999., Results: Altogether, 889 invasive CRCs were diagnosed among Olmsted County residents from 1980 through 1999. Annual age- and sex-adjusted CRC incidence rates decreased significantly during this period (P = .02) with a 23% decline from 60 per 100,000 in 1980-1984 to 46 per 100,000 in 1995-1999. This was primarily accounted for by a 40% reduction in left-sided CRC (P < .001). The incidence of right-sided CRC remained unchanged, but the proportion of right-sided CRC increased from 46% to 58%. Cancer stage shifted downward, and survival improved over time. The overall proportion of screen-detected CRC rose from 8% to 17%. Annual adjusted adenomatous polypectomy rates increased dramatically from 86 to 320 per 100,000 (P < .001)., Conclusions: The incidence of CRC in Olmsted County has declined in recent years. An impact of screening is suggested by the observed upward trend in screen-detected cases, a favorable stage shift, and a concurrent rise in polypectomy rates. However, the incidence of right-sided cancer remains unaltered and might be less affected by historically used screening interventions. Most CRCs still present symptomatically, and more effective population screening is needed.

Objective: To determine whether unexplained gastrointestinal (GI) symptoms are more common in people with self-reported sleep disturbance., Participants and Methods: From November 1988 to June 1994, valid self-report questionnaires were mailed to age- and sex-stratified random samples of Olmsted County, Minnesota, residents aged 20 to 95 years., Results: Of 2269 study participants (74% response rate), 52% were women (mean age, 45.0 years). The overall age- and sex-adjusted prevalence of sleep disturbance per 100 population was 13.5% (95% confidence interval [CI], 11.7%-15.3%). Among study participants with sleep disturbance, the prevalence of irritable bowel syndrome (IBS) was 33.3% (95% CI, 26.0%-40.5%) and the prevalence of frequent dyspepsia (FD) was 21.3% (95% CI, 14.4%-28.2%). After adjusting for age, sex, and somatization score, IBS was significantly more common in those with sleep disturbance (odds ratio, 1.6; 95% CI, 1.1-2.2), but the univariate association with FD was no longer statistically significant (odds ratio, 1.3; 95% CI, 0.9-1.9)., Conclusions: Both IBS and FD are prevalent in those with self-reported sleep disturbance. Sleep disturbance was independently associated with IBS but not FD in the general population.
