Abstract
Background The most common complication following ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis (UC) is pouchitis. Our study aimed to investigate the relationship between histopathologic findings of ileitis, granuloma, or transmural inflammation on the colectomy specimen of patients with clinically and endoscopically diagnosed UC and the development of pouchitis within the first 2 years after IPAA. Methods We performed a retrospective cohort study evaluating patients undergoing colectomy with IPAA for UC between January 1, 2004 and December 31, 2016. Bivariate analyses were conducted to evaluate the relationship between clinical factors and the development of pouchitis. We performed multivariate logistic regression to evaluate the relationship between histologic, clinical, and demographic factors at the time of colectomy and subsequent development of pouchitis. Results Among 626 patients, pouchitis occurred in 246 (39%). Patients with primary sclerosing cholangitis were more likely to develop pouchitis (adjusted odds ratio [aOR] 2.81, 95% confidence interval [CI] 1.02-7.72), as were patients with a family history of inflammatory bowel disease (aOR 1.75, 95% CI 1.11-2.77). Histologic findings of ileitis, granuloma, or transmural inflammation were not associated with an increased odds of developing pouchitis (aOR 0.70, 95% CI 0.45-1.08). Discussion/Conclusion Patients with ileitis, granulomas, or transmural inflammation at the time of colectomy were not at greater risk for development of pouchitis in the 2 years after IPAA. These pathological findings should not preclude IPAA for UC.

Abstract
Acute pouchitis is the most common complication after a restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis, affecting 40% of patients within the first year after surgery.1 Although up to 80% of patients can develop pouchitis symptoms,2,3 substantial gaps remain in our understanding of the epidemiology and burden of pouchitis. Administrative claims have been used to advance the knowledge of other areas of inflammatory bowel disease4-6; however, a prerequisite to conducting such studies in pouchitis is a valid, reliable case-finding algorithm. Given concerns that the International Classification of Diseases (ICD) code for pouchitis may not be reliably used by clinicians (resulting in a low sensitivity), the objectives of the study were to (1) develop a series of case-finding definitions for acute pouchitis and (2) compare the performance of these case-finding definitions to that of a single ICD code for pouchitis.

Abstract
BACKGROUND Risk factors for the development of chronic antibiotic dependent pouchitis (CADP) are not well understood. METHODS Using multivariable logistic regression, we compared clinical factors between 194 patients with acute antibiotic responsive pouchitis or CADP. RESULTS Individuals with CADP were significantly older (40.9 vs 30.8 years, P < 0.001) and demonstrated a longer disease duration before IPAA (10.3 vs 7.0 years, P = 0.004). Age ≥55 years at the time of IPAA was significantly associated with CADP (adjusted odds ratio = 4.35, 95% confidence interval = 1.01-18.7). CONCLUSIONS Although older age should not represent a barrier to IPAA, further studies evaluating etiologies of this association are warranted.

Abstract
BACKGROUND Ulcerative colitis (UC) patients requiring colectomy often have a staged ileal pouch anal anastomosis (IPAA). There are no prospective data comparing timing of pouch creation. We aimed to compare 30-day adverse event rates for pouch creation at the time of colectomy (PTC) with delayed pouch creation (DPC). METHODS Using prospectively collected data from 2011-2015 through the National Surgical Quality Improvement Program, we conducted a cohort study including subjects aged ≥18 years with a postoperative diagnosis of UC. We assessed 30-day postoperative rates of unplanned readmissions, reoperations, and major and minor adverse events (AEs), comparing the stage of the surgery where the pouch creation took place. Using a modified Poisson regression model, we estimated risk ratios (RRs) with 95% confidence intervals (CIs) adjusting for age, sex, race, body mass index, smoking status, diabetes, albumin, and comorbidities. RESULTS Of 2390 IPAA procedures, 1571 were PTC and 819 were DPC. In the PTC group, 51% were on chronic immunosuppression preoperatively, compared with 15% in the DPC group (P < 0.01). After controlling for confounders, patients who had DPC were significantly less likely to have unplanned reoperations (RR, 0.42; 95% CI, 0.24-0.75), major AEs (RR, 0.72; 95% CI, 0.52-0.99), and minor AEs (RR, 0.48; 95% CI, 0.32-0.73) than PTC. CONCLUSIONS Patients undergoing delayed pouch creation were at lower risk for unplanned reoperations and major and minor adverse events compared with patients undergoing pouch creation at the time of colectomy. 10.1093/ibd/izy082_video1izy082.video15776112442001.

Abstract
BACKGROUND & AIMS Despite the availability of endoscopic therapy, many patients in the United States undergo surgical resection for nonmalignant colorectal polyps. We aimed to quantify and examine trends in the use of surgery for nonmalignant colorectal polyps in a nationally representative sample. METHODS We analyzed data from the Healthcare Cost and Utilization Project National Inpatient Sample for 2000 through 2014. We included all adult patients who underwent elective colectomy or proctectomy and had a diagnosis of either nonmalignant colorectal polyp or colorectal cancer. We compared trends in surgery for nonmalignant colorectal polyps with surgery for colorectal cancer and calculated age, sex, race, region, and teaching status/bed-size-specific incidence rates of surgery for nonmalignant colorectal polyps. RESULTS From 2000 through 2014, there were 1,230,458 surgeries for nonmalignant colorectal polyps and colorectal cancer in the United States. Among those surgeries, 25% were performed for nonmalignant colorectal polyps. The incidence of surgery for nonmalignant colorectal polyps has increased significantly, from 5.9 in 2000 to 9.4 in 2014 per 100,000 adults (incidence rate difference, 3.56; 95% confidence interval 3.40-3.72), while the incidence of surgery for colorectal cancer has significantly decreased, from 31.5 to 24.7 surgeries per 100,000 adults (incidence rate difference, -6.80; 95% confidence interval -7.11 to -6.49). The incidence of surgery for nonmalignant colorectal polyps has been increasing among individuals age 20 to 79, in men and women and including all races and ethnicities. CONCLUSIONS In an analysis of a large, nationally representative sample, we found that surgery for nonmalignant colorectal polyps is common and has significantly increased over the past 14 years.

Abstract
BACKGROUND AND AIMS Despite evidence that most nonmalignant colorectal polyps can be managed endoscopically, a substantial proportion of patients with a nonmalignant colorectal polyp are still sent to surgery. Risks associated with this surgery are not well characterized. We describe 30-day postoperative morbidity and mortality and explore risk factors for adverse events in patients undergoing surgical resection for nonmalignant colorectal polyps. METHODS We analyzed data collected prospectively as part of the National Surgical Quality Improvement Program. Our analysis included 12,732 patients who underwent elective surgery for a nonmalignant colorectal polyp from 2011 through 2014. We report adverse events within 30 days of the index surgery. Modified Poisson regression was used to estimate risk ratios and 95% confidence intervals. RESULTS Thirty-day mortality was .7%. The risk of a major postoperative adverse event was 14%. Within 30 days of resection, 7.8% of patients were readmitted and 3.6% of patients had a second major surgery. The index surgery resulted in a colostomy in 1.8% and ileostomy in .4% of patients. Patients who had surgical resection of a nonmalignant polyp in the rectum or anal canal compared with the colon had a risk ratio of 1.58 (95% confidence interval, 1.09-2.28) for surgical site infection and 6.51 (95% confidence interval, 4.97-8.52) for ostomy. CONCLUSIONS Surgery for a nonmalignant colorectal polyp is associated with significant morbidity and mortality. A better understanding of the risks and benefits associated with surgical management of nonmalignant colorectal polyps will better inform discussions regarding the relative merits of management strategies.

Abstract
BACKGROUND Ulcerative colitis patients have been historically treated with standard single, 2-, and 3-stage operative approaches. We perform a variant 2-stage procedure beginning with total abdominal colectomy and end ileostomy followed by completion proctectomy and ileal pouch-anal anastomosis (IPAA) without a diverting loop ileostomy. This study evaluates the effectiveness of this innovative alternative. STUDY DESIGN Patients with ulcerative colitis, admitted to the University of North Carolina Hospital between 2003 and 2010 for IPAA, were eligible for inclusion. The 3-year cumulative incidence of pouch leaks among patients undergoing variant 2-stage were compared with those undergoing classic 2-stage, using inverse probability-of-treatment weighted Kaplan- Meier survival curves, and 95% CIs were estimated using nonparametric bootstrapping. RESULTS There were 248 patients who underwent IPAA; 139 (56.1%) underwent classic 2-stage and 109 (43.9%) underwent variant 2-stage. After standardization, there was no significant difference in the 3-year cumulative incidence of pouch leaks between patients undergoing variant 2-stage, compared with the standard single- or 2-stage procedure (risk difference 0.01; 95% CI -0.08, 0.15). At the time of the first surgical procedure, patients undergoing a variant 2-stage were more likely to have lower BMIs (median 22.5 kg/m2 vs 26.7 kg/m2; p < 0.0001), an urgent/emergent procedure (56.9% vs 0.0%; p < 0.0001), biologic use within 2 weeks of surgery (32.1% vs 17.5%; p = 0.003), and high dose steroid use (60.4% vs 16.7%; p ≤ 0.0001). CONCLUSIONS Variant 2-stage IPAA is a safe and effective operative approach with comparable outcomes in a more acute population based on BMI, steroid use, and urgency of operation.

Abstract
BACKGROUND Adhesions can result in serious clinical complications and make ileostomy closure, which is relatively simple procedure into a complicated and prolonged one. The use of sodium hyaluronate and carboxymethyl cellulose membrane (Seprafilm) was proven to significantly reduce the postoperative adhesions at the site of application. The aim of this study was to assess the incidence and severity of adhesions around a loop ileostomy and to analyze the length of time and morbidity for mobilization at the time of ileostomy closure with and without the use of Seprafilm. METHODS Twenty-nine surgeons from 15 institutions participated in this multicenter prospective randomized study. 191 patients with loop ileostomy construction were randomly assigned to either receive Seprafilm under the midline incision and around the stoma (Group I), only under the midline incision (Group II), or not to receive Seprafilm (Group III). At ileostomy closure, adhesions were quantified and graded; operative morbidity was also measured. RESULTS All 3 groups were comparable relative to gender, mean age and number of patients with prior operations (26, 25 and 19, respectively). Group II patients were significantly more likely to have pre-existing adhesions than Group III patients (30.6% vs. 14.1%, p = 0.025). At stoma mobilization, significantly more patients in Group III than in Group I had adhesions around the stoma (95.2% vs. 82.3%, p = 0.021). Mean operative times were 27, 25, and 28 minutes, respectively (p = 0.38), with significant differences among sites. There was no significant difference in the number of patients needing myotomy or enterotomy (29, 27 and 24 patients, respectively), nor in the number of postoperative complications (7, 9 and 7 patients, respectively). CONCLUSIONS When consistently applied, Seprafilm significantly decreased adhesion formation around the stoma but not operative times without any increase in the need for myotomy or enterotomy. These findings were not seen in the overall study population possibly due to the large number of surgeons using a variety of application techniques.

Abstract
BACKGROUND We conducted a phase I study to determine the maximum tolerated dose of docetaxel in combination with gemcitabine for patients with refractory solid tumors. METHODS From January 1998 to November 1999, we treated 28 patients on a phase I protocol with gemcitabine given at a constant dose of 800 mg/m2 i.v. over 30 minutes on days 1, 8, and 15. Docetaxel was administered by a phase I schedule over 1 hour on day 1 of a 28-day cycle with a starting dose of 50 mg/m2 and increased by increments of 10 mg/m2 based on dose-limiting toxicity (DLT) that occurred in the first cycle. RESULTS Neutropenia and thrombocytopenia were the dose-limiting toxicities. The maximum tolerated dose was 60 mg/m2. The most significant nonhematologic toxicities included fatigue, nausea, vomiting, mucositis, and hypersensitivity reactions. There was one partial response at 15 months in a patient with gastric cancer and six patients with stable disease for 4.0 to 15.0 months. CONCLUSIONS The maximum tolerated dose of docetaxel with gemcitabine is 60 mg/m2. A Phase II study in selected primary sites is planned.

Abstract
Increased gut permeability (GP) following burn injury has been implicated in the predisposition to sepsis and multiple systems organ failure (MSOF). Since previous studies have identified only "global" alterations in GP, we examined the jejunum, ileum, and colon individually for GP using probes of two different sizes: fluorescein isothiocyanate-dextran-3 (FDEX, molecular weight 4387 d) and horseradish peroxidase (HRP, molecular weight 40,000 d). Animals were examined for GP at 1, 2, or 4 days following burn. The GP was significantly increased in all segments combined following burn injury to both the small probe (FDEX, p < 0.001) and the larger probe (HRP, p < 0.06) versus controls. The GP was significantly greater for FDEX versus HRP (p < 0.001). Jejunal permeability to FDEX and HRP increased most at 24 hours. Ileal and colonic GP to FDEX increased early also, but were higher at days 2 and 4. These results suggest that, following burn injury, there is differential GP that is size and site dependent, and that increased GP may last well beyond 24 hours postburn despite feeding.

Abstract
We compared the first year's experience in performing laparoscopic cholecystectomy in a university hospital and a community hospital to determine the impact of postgraduate surgical training on outcome. Laparoscopic cholecystectomy was attempted on 446 patients. The conversion rate to open cholecystectomy was 8.3% and did not differ between institutions. Surgical house staff performed 43% of the cases at the university hospital compared with 8% at the community hospital. The greater use of laser and cholangiograms resulted in significantly longer mean operative time at the university hospital (141 +/- 26 min) than at the community hospital (114 +/- 52 min). The overall complication rate did not differ significantly (p = 0.15). Complications included common duct injury (three cases), bile leak (five cases), bleeding or hematoma (six cases), epigastric artery hematoma (one case), and death (one case). Operative inexperience during this first year may be a major determinant for the complication rates at both hospitals. It is too early to determine the impact of graduate surgical education on complications. Intense education and supervised instruction is requisite to minimizing the morbidity associated with laparoscopic cholecystectomy regardless of whether it is performed at a university or community hospital.

Abstract
Adinazolam is a triazolobenzodiazepine with anxiolytic and antidepressant activity. Adinazolam is metabolized extensively; the major metabolite, N-desmethyladinazolam (NDMAD), possesses significant pharmacologic activity. NDMAD is eliminated predominantly by renal excretion. Ranitidine, a histamine H2-receptor antagonist, is also excreted renally and may compete with NDMAD for renal secretion. The purpose of this study was to examine the effect of ranitidine on the pharmacokinetics and pharmacodynamics of adinazolam and NDMAD. In a randomized, cross-over study, 12 healthy male volunteers received 300 mg of ranitidine orally followed by 30 mg of adinazolam 1 hour later (treatment A), or adinazolam alone (treatment B). Pharmacodynamic alterations were assessed using card sorting, digit-symbol substitution, and short-term memory tests. Venous blood samples were obtained over 24 hours for analysis of adinazolam and NDMAD by high-performance liquid chromatography. Urine samples also were collected and analyzed for NDMAD. No significant difference in adinazolam oral clearance (1,149 vs. 1,135 ml/hr/kg) was noted between treatments (A vs. B, respectively). Furthermore, the renal clearance of NDMAD (196 vs. 198 ml/min) and the cumulative urinary excretion of NDMAD (% dose; 61.2 vs. 62.3) were not significantly different. Repeated-measures analysis of variance indicated no significant differences in psychomotor performance or short-term memory between treatments. Results suggest that ranitidine has no effect on adinazolam disposition, NDMAD renal clearance, or the central nervous system effects mediated by the drug.

Abstract
OBJECTIVE To assess the statistical association of the Acute Physiology and Chronic Health Evaluation (APACHE II) score with multiple intervention and outcome variables in surgical ICU patients. DESIGN Continuous data collection on every patient admitted to the surgical ICU for a 21-month period. MATERIALS AND METHODS For every admitted patient in the surgical ICU, APACHE II scores were calculated and the relationship between APACHE II score as an independent predictor of outcome was assessed with multiple outcome variables selected for study. The outcome and intervention variables tested included: treatment intervention measures such as days on ventilator; days with an arterial catheter, central venous catheter, triple lumen catheter, pulmonary artery catheter; days receiving total parenteral nutrition; days receiving tube feedings; number of transducers per days in the ICU; number of infusion pumps per ICU days, days in the hospital, number of complete blood counts; number of electrolyte determinations; number of blood gases; number of units of blood transfused; ICU and hospital mortality rates in the presence of complications, including: respiratory distress syndrome, renal failure, congestive heart failure, coma, requirement of cardiopulmonary resuscitation, and others. RESULTS The APACHE II score was statistically associated with each intervention and outcome variable tested. Unfortunately, the associations, although consistent, were weak with r2 values ranging from .03 to a maximum of .22 for Pearson's correlation coefficients. CONCLUSION The APACHE II score was statistically associated with all the variables examined in our surgical patients, but its predictive power for the individual surgical patient was limited. These findings suggest that the score may be useful for retrospective analyses of large cohorts of patients but should not be used as a triage tool or as a predictor of outcome for the individual patient. Triage decisions should continue to be based on the best available clinical judgment.

Abstract
Theoretical consideration and experimental findings of 31P nuclear magnetic resonance spectroscopy (NMR) studies of exercising human muscle suggest that a graded, steady-state work protocol is highly suitable for performance evaluation in health and disease. We describe a similar rat model for repeated 31P-NMR studies that follows many of the 31P-NMR features observed in normal human controls. Calf muscles of rats anesthetized with chloral hydrate were indirectly stimulated at four frequencies (0.25, 0.5, 1.0, and 2.0 Hz). It was found that 1) several steady states can be briefly maintained in this model; 2) work-induced phosphocreatine (PCr) fall and inorganic phosphate (Pi) rise is stoichiometric; 3) a linear relationship between stimulation rate and Pi/PCr was obtained, with a slope of 2.01 +/- 0.4 (+/- 2SD, n = 15); 4) no significant drop in ATP was observed, allowing the estimation of phosphorylation potential (PP) changes during this range of muscle work (PP at rest was 61,603 +/- 25,100 M-1 and fell to 6,700 +/- 900 M-1 at the end of exercise); and 5) poststimulation recovery was rapid, with a rate of 2.27 +/- 0.5 PCr/Pi U/min. This simple model can be used for prolonged studies of chronic animal muscle disorders.

Abstract
Four relatively new techniques that apply electromagnetic or sound waves promise to play a major role in the study of human body composition and in clinical nutritional assessment. Computerized axial tomography, nuclear magnetic resonance, infrared interactance, and ultrasonography provide capabilities for measuring the following: total body and regional fat volume; regional skeletal muscle volume; brain, liver, kidney, heart, spleen, and tumor volume; lean tissue content of triglyceride, iron, and high-energy intermediates; bone density; and cardiac function. Each method is reviewed with regard to basic principles, research and clinical applications, strengths, and limitations.
