Surgical site infections (SSI) can represent a major complication of pancreaticoduodenectomy (PD). We summarize the outcomes of process improvement efforts to reduce the SSI rates in PD that includes replacing Cefazolin with Ceftriaxone-Metronidazole as antibiotic prophylaxis. Additional efforts included current assessment of biliary microbiome and potential prophylactic failures based on bile cultures and suspected antibiotic allergies.A single-center review of PD patients from January-2012 to March-2021. Study groups were divided into Pre and Post May-2015 (Group 1 and 2, respectively) when Ceftriaxone-Metronidazole prophylaxis and routine intraoperative cultures were standardized. Univariate and multivariable analyses were conducted to assess groups' differences and association with SSI.Six hundred ninety patients identified [267(38.7%) and 423(61.3%) in Group 1 and Group2, respectively]. After antibiotic change, SSI rates decreased from 28.1% to 16.5% (incisional: 17.6%-7.5%, organ-space or abscess: 17.2%-13.0%), Group 1 and Group 2, respectively, P0.001. Ceftriaxone-Metronidazole was used in 75.9% of patients Group 2. When adjusting for other covariates, an SSI-decrease was associated only with Ceftriaxone-Metronidazole (OR 0.34, P0.001).Ongoing process improvement has resulted in decreased SSIs with Ceftriaxone-Metronidazole prophylaxis. The benefit of Ceftriaxone-Metronidazole is independent of the biliary microbiome. Improving prophylaxis for those with suspected penicillin allergy is warranted.

ImportanceThe benefits from colorectal cancer (CRC) screening may take 10 to 15 years to accrue. Therefore, screening is recommended for older adults who are in good health.ObjectiveTo determine the number of screening colonoscopies done in patients older than 75 years with a life expectancy of fewer than 10 years, diagnostic yield, and associated adverse events within 10 days and 30 days of the procedure.DesignThis cross-sectional study with a nested cohort between January 2009 and January 2022 in an integrated health system assessed asymptomatic patients older than 75 years who underwent screening colonoscopy in the outpatient setting. Reports with incomplete data, any indication other than screening, patients who had a colonoscopy within the previous 5 years, and patients with a personal history of inflammatory bowel disease or CRC were excluded.ExposuresLife expectancy based on a prediction model from previous literature.Main Outcomes and MeasuresThe primary outcome was the percentage of screened patients who had limited (ResultsA total of 7067 patients older than 75 years were included. The median (IQR) age was 78 (77-79) years, 3967 (56%) were women, and 5431 (77%) were White with an average of 2 comorbidities (taken from a select group of comorbidities). The proportion of colonoscopies performed on patients with a life expectancy of fewer than 10 years aged 76 to 80 years was 30% in both sexes and increased with age—82% of men and 61% of women aged 81 to 85 years (71% total), and 100% of patients beyond the age of 85 years. Adverse events requiring hospitalizations were common at 10 days (13.58 per 1000) and increased with age, particularly among patients older than 85 years. The detection of advanced neoplasia varied from 5.4% among patients aged 76 to 80 years to 6.2% in those aged 81 to 85 years and 9.5% among patients older than 85 years (P = .02). Of the total population, 15 patients (0.2%) had invasive adenocarcinoma; among patients with a life expectancy of fewer than 10 years, 1 of 9 was treated, whereas 4 of 6 patients with a life expectancy of greater than or equal to 10 years were treated.Conclusions and RelevanceIn this cross-sectional study with a nested cohort, most screening colonoscopies performed in patients older than 75 years were in patients with limited life expectancy and associated with increased risk of complications. Colorectal cancer was exceedingly rare.

Chronic intestinal pseudo-obstruction (CIP) is a rare motility disorder characterized by dilated small bowel in the absence of mechanical obstruction. CIP has a known association with small intestinal bacterial overgrowth (SIBO); however, data regarding association with specific subtypes such as methane-positive (M+) and hydrogen-positive (H+) SIBO are limited. Therefore, we conducted this study to characterize subtypes of SIBO in CIP and compare them with non-CIP patients.The aim is to explore the association and prevalence of hydrogen and methane subtypes of SIBO in patients with CIP.A retrospective chart review was conducted for 494 patients who underwent glucose breath tests (GBT) in 2019. CIP was diagnosed based on clinical suspicion and after ruling out mechanical obstruction. We also reviewed demographic data, including age, gender, body mass index, tobacco and alcohol history, medical comorbidities, use of proton pump inhibitors, and history of colectomy.Among 494 patients, 7.7% (38) had CIP. The prevalence of M+ GBT in CIP patients was higher compared with non-CIP patients, and it was significant [52.6% (20/38) versus 11.8% (54/456), p 0.001]. The prevalence of H+ GBT in our cohort of CIP patients was similar to that of non-CIP patients [23.7% (9/38) versus 25.7% (117/456), p = 0.941].The prevalence of methane-positive GBT was higher in CIP patients than in patients without CIP. This finding further strengthens the hypothesis that the relationship between motility disorders and methanogen overgrowth is facilitative.

OBJECTIVES Islet cultures are routinely performed in total pancreatectomy with islet autotransplantation (TPIAT), and the need for empiric antibiotic treatment based on culture results is unknown. We evaluated the effect of postoperative antibiotic treatment for positive islet cultures on clinical infection. METHODS Seventy-nine patients undergoing TPIAT were reviewed. Prophylactic perioperative ceftriaxone and metronidazole were administered, and transplanted islet preparations included ciprofloxacin. Postoperative antibiotics were not routinely given for positive cultures unless a clinical infection was suspected. The primary end point was 30-day infectious complications. RESULTS Fifty-one patients (65%) had a positive culture. Overall, 39 patients (87%) had organisms susceptible to our perioperative antibiotic regimen. There was no difference in the infectious complication rate between those with positive compared with negative cultures (16% vs 29%, P = 0.17). Patients with a positive culture had similar 30-day postoperative infectious complication rates whether receiving postoperative antibiotics (n = 7) or not (14% vs 16%, P = 0.91). Only 1 patient had a correlation of clinical and islet cultures. CONCLUSIONS Beyond prophylactic antibiotics, empiric antibiotic treatment for a positive culture is not warranted and provides a rationale for the abandonment of routine cultures in TPIAT.

Aim In patients with anorectal Crohn's disease, it remains uncertain whether a total proctocolectomy with end ileostomy or proctectomy with end colostomy should be recommended due to the unknown rate of disease recurrence in the remaining colon. Methods A retrospective review of all patients with a known diagnosis of Crohn's disease who underwent a proctectomy with end colostomy for distal Crohn's disease between January 1, 2010 and January 1, 2019 at two IBD referral centres was conducted. Data collected included patient demographics, surgical variables at the time of proctectomy, and postoperative clinical, endoscopic and surgical recurrence rates. Results A total of 63 patients were included; mean age was 47 years (SD 15 years) and 32 (50.8%) were female. The majority of patients underwent a proctectomy with end colostomy (n = 56; 88.9%) while the remaining seven patients (11.1%) underwent a proctectomy with end colostomy and concurrent ileocectomy. A total of 55 patients (87.3%) had proctitis, 51 (81%) had perianal fistulating disease, and 34 (54%) had anal canal stenosis or ulceration. Most patients had medically refractory disease (n = 54; 85.7%) versus neoplasia (n = 9; 14.3%). The median length of long-term follow-up was 17.7 months (IQR: 4.72, 38.7 months). During that time, 14 (22.2%) experienced clinical recurrence, 10 of 34 evaluated (29.4%) had endoscopic recurrence, and 3 (4.76%) required a completion total abdominal colectomy for recurrent medically refractory disease in the colon. Conclusion Colonic recurrence remains low following proctectomy and descending colostomy suggesting this operative management strategy is reasonable in Crohn's patients with distal disease.

Socioeconomic disparities adversely affected healthcare use during COVID-19 lockdown. However, trends in these disparities post lockdown are unknown. Therefore, our aim was to study temporal trends and factors associated with gastroenterology healthcare access and disparities during and after COVID-19 lockdown. This cohort study consisted of patients receiving outpatient care in the Cleveland Clinic gastroenterology department between March 2020 and June 2020 and corresponding time periods in 2019 and 2021. Patient demographics and socioeconomic factors were extracted and analyzed. There were 47,031 patients (mean age 56.3±17.6 years, 61.9% female and 76.4% white) included. Patients ≥65 years sought healthcare less frequently during and after the lockdown (40.1% vs 34.8% vs 35.2% in 2019, 2020, and 2021 respectively). Missed visits (4.2% vs 10% vs 10.4%), tobacco (11.4% vs 15.9% vs 16.1%), alcohol (38.6% vs 45.5% vs 50.9%), and illicit drug use (3.5% vs 5.8% vs 10.7%) have steadily increased during and after the lockdown compared with prepandemic levels. Factors associated with reduced telehealth use were black race (OR 0.89, 95% CI 0.81 to 0.99), Hispanic race (OR 0.63, 95% CI 0.51 to 0.77)), Medicaid/other public insurance (OR 0.87, 95% CI 0.79 to 0.95)), unemployed status (OR 0.85, 95% CI 0.79 to 0.92)), and non-English/Spanish speakers (OR 0.66, 95% CI 0.46 to 0.94)). In conclusion, socioeconomic and ethnic disparities persist in healthcare use even a year after the onset of the COVID-19 pandemic. There is an alarming increase in missed visits and substance abuse. Therefore, efforts should be targeted on improving healthcare access for these aforementioned vulnerable groups.

Goals and background Clinical staging with endoscopic ultrasound (EUS) and positron emission tomography (PET) is used to identify esophageal adenocarcinoma (EAC) patients with locally advanced disease and therefore, benefit from neoadjuvant therapy. However, EUS is operator dependent and subject to interobserver variability. Therefore, we aimed to identify clinical predictors of locally advanced EAC and build a predictive model that can be used as an adjunct to current staging methods. Study This was a cross-sectional study of patients with EAC who underwent preoperative staging with EUS and PET scan followed by definitive therapy at our institution from January 2011 to December 2017. Demographic data, symptoms, endoscopic findings, EUS, and PET scan findings were obtained. Results Four hundred and twenty-six patients met the study criteria, of which 86 (20.2%) patients had limited stage EAC and 340 (79.8%) had locally advanced disease. The mean age was 65.4±10.3 years of which 356 (83.6%) were men and 393 (92.3%) were White. On multivariable analysis, age (above 75 or below 65 y), dysphagia [odds ratio (OR): 2.84], weight loss (OR: 2.06), protruding tumor (OR: 2.99), and tumor size >2 cm (OR: 3.3) were predictive of locally advanced disease, while gastrointestinal bleeding (OR: 0.36) and presence of visible Barrett's esophagus (OR: 0.4) were more likely to be associated with limited stage. A nomogram for predicting the risk of locally advanced EAC was constructed and internally validated. Conclusions We constructed a nomogram to facilitate an individualized prediction of the risk of locally advanced EAC. This model can aid in decision making for neoadjuvant therapy in EAC.

Total pancreatectomy with islet autotransplantation (TP-IAT) is an uncommon surgical procedure with unique perioperative management. We evaluated the short- and long-term morbidity and mortality of TP-IAT to optimize surgical technique and heparin dosing during islet autotransplantation.Eighty patients with chronic pancreatitis undergoing TP-IAT were reviewed. Primary outcome was to evaluate morbidity and mortality based on operative technique: classic (resection of antrum) vs pylorus-preserving. Secondary outcome was to evaluate the effect of heparin dosing (60 vs ≥ 60 units/kg) during islet autotransplantation on postoperative hemorrhage and portal vein thrombosis (PVT) rates.There was no 90-day mortality, and median length of stay was 9 days. All patients underwent an open operation with 53 (66%) pylorus-preserving resections. The 30-day morbidity rate was 39%, with no difference between operative technique (p = 0.82). The median dose was different for each heparin group (60: 52 units/kg vs ≥ 60: 66 units/kg, p 0.0001). No difference was observed in postoperative hemorrhage rates between heparin groups (60: 9% vs ≥ 60: 9%, p = 0.97), with no known incidence of PVT. Median follow-up was 36 months (IQR, 14-71). Morbidity30 days after TP-IAT was 43% with a higher rate in the pylorus-preserving group (55% vs 15%, p 0.0001), mainly attributed to marginal ulcer formation (15% vs 0%, p = 0.03).A classic TP-IAT technique should be universally adopted to achieve optimal outcomes, particularly to prevent the formation of marginal ulcers. When considering PVT versus postoperative hemorrhage risk, a lower heparin dose nearing 50 units/kg is optimal. These findings highlight potential areas for future improvement.

Despite the high prevalence of asymptomatic gallstones (AGs), there are limited data on their natural history. We aimed to determine the rate of symptom development in a contemporary population, determine factors associated with progression to symptomatic gallstones (SGs), and develop a clinical prediction model.We used a retrospective cohort design. The time to first SG was shown using Kaplan-Meier curves. Multivariable competing risk (death) regression analysis was used to identify variables associated with SGs. A prediction model for the development of SGs after 10 years was generated and calibration curves were plotted. Participants were patients with AGs based on ultrasound or computed tomography from the general medical population.From 1996 to 2016, 22,257 patients (51% female) with AGs were identified; 14.5% developed SG with a median follow-up period of 4.6 years. The cumulative incidence was 10.1% (±0.22%) at 5 years, 21.5% (±0.39%) at 10 years, and 32.6% (±0.83%) at 15 years. In a multivariable model, the strongest predictors of developing SGs were female gender (hazard ratio [HR], 1.50; 95% CI, 1.39-1.61), younger age (HR per 5 years, 1.15; 95% CI, 1.14-1.16), multiple stones (HR, 2.42; 95% CI, 2.25-2.61), gallbladder polyps (HR, 2.55; 95% CI, 2.14-3.05), large stones (HR, 2.03; 95% CI, 1.80-2.29), and chronic hemolytic anemia (HR, 1.90; 95% CI, 1.33-2.72). The model showed good discrimination (C-statistic, 0.70) and calibration.In general medical patients with AGs, symptoms developed at approximately 2% per year. A predictive model with good calibration could be used to inform patients of their risk of SGs.

Background In patients with resectable esophageal adenocarcinoma (EAC), the decision for neoadjuvant treatment depends on clinical staging with endoscopic ultrasound (EUS) and positron-emission tomography (PET) scan. Patients with locally advanced EAC pathology misclassified as early EAC by clinical staging are missing the opportunity to receive neoadjuvant therapy. We aim to identify predictors of locally advanced pathology in EAC to determine more accurately those who benefit from neoadjuvant therapy. Methods Retrospective study of patients who underwent upfront endoscopic or surgical resection for EAC without neoadjuvant therapy from January 2011 to December 2017 was performed. Clinical characteristics, EUS, PET scan and histologic findings were analyzed. Multivariable analysis of predictors of locally advanced stage was performed and a risk prediction score was developed. Results A total of 97 patients were included; 68 patients were staged as early EAC (pT1 or pT2 and pN0) and 29 patients were staged as locally advanced EAC (pT1 or pT2 with pN1 and pT3 or pT4 irrespective of N status). In a predictive model of EAC, patients presenting with dysphagia, tumor size >2 cm, exophytic mass appearance on endoscopy and absence of hiatal hernia were more likely to be have locally advanced pathology with a probability of 70% (C-statistic 0.766). Conclusions A risk prediction model based on the presence of dysphagia, tumor size >2 cm, exophytic mass appearance and absence of hiatal hernia can be used to identify locally advanced pathology in EAC patients.

Background Recommendations regarding management of colorectal dysplasia in the setting of IBD continue to evolve. Objective This study aimed to determine the rate of progression from dysplasia to adenocarcinoma, specifically focusing on the differences in unifocal and multifocal low-grade dysplasia and dysplasia found on random biopsy versus targeted biopsies. Design This is a retrospective review. Setting This study was conducted at an IBD referral center. Patients All adult patients (≥18 years of age) with a known diagnosis of either ulcerative colitis or Crohn's disease, who underwent a surveillance colonoscopy between January 1, 2010 and January 1, 2019, were selected. Main outcomes measures The primary outcomes measured were the progression of dysplasia and the risk factors for progression. Results A total of 23,751 surveillance colonoscopies were performed among 12,289 patients between January 1, 2010 and January 1, 2019. The mean age at colonoscopy was 52.1 years (SD 16.9 years), 307 patients (2.5%) had a history of primary sclerosing cholangitis, and 3887 (3.15%) had a family history of colorectal cancer. There was a total of 668 patients (5.4%) with low-grade dysplasia, 76 patients (0.62%) with high-grade dysplasia, and 68 patients (0.55%) with adenocarcinoma in the series. The 1-, 2-, and 5-year cumulative incidence rate of progressing from low-grade dysplasia to high-grade dysplasia were 1.6%, 4.8%, and 7.8%. The 1- and 2-year cumulative incidence rates of progressing from low-grade dysplasia to adenocarcinoma were 0.7% and 1.6%. There were no significant differences in unifocal and multifocal progression. Primary sclerosing cholangitis, ulcerative colitis, male sex, and advanced age were all found to be significant risk factors for neoplasia on multivariable analysis. Limitations A retrospective database was a source of information. Conclusion Progression of low-grade dysplasia to adenocarcinoma, regardless of its being unifocal or multifocal, remains very low in the setting of adequate surveillance and medical management. The presence of multifocal low-grade dysplasia should not change the decision making to pursue ongoing endoscopic surveillance versus proctocolectomy. Patients who had primary sclerosing cholangitis with dysplasia found on random biopsies may be at highest risk for dysplasia progression. See Video Abstract at http://links.lww.com/DCR/A649. El desenlace de la displasia de bajo grado unifocal versus multifocal durante la colonoscopia en pacientes con enfermedad inflamatoria intestinal ANTECEDENTES:Las recomendaciones para el tratamiento de la displasia colorrectal en el contexto de la enfermedad inflamatoria intestinal siguen evolucionando.OBJETIVO:Determinar la tasa de progresion de displasia a adenocarcinoma, centrandose especificamente en las diferencias en displasia de bajo grado unifocal y multifocal, y displasia encontradas en biopsias aleatorias versus biopsias dirigidas.DISENO:Revision retrospectiva.AMBITO:Centro de referencia de EII.PACIENTES:Todos los pacientes adultos (> 18 anos) con un diagnostico comprobado de colitis ulcerosa o enfermedad de Crohn que se sometieron a una colonoscopia de vigilancia entre el 1 de enero de 2010 y el 1 de enero de 2019.PRINCIPALES VARIABLES ANALIZADAS:Progresion de la displasia y factores de riesgo de progresion.RESULTADOS:Se realizaron un total de 23.751 colonoscopias de vigilancia en 12.289 pacientes entre el 1/1/2010 y el 1/1/2019. La edad media en el momento de la colonoscopia fue de 52,1 anos (DE 16,9 anos), 307 pacientes (2,5%) tenian antecedentes de colangitis esclerosante primaria y 3887 (3,15%) tenian antecedentes familiares de cancer colorrectal. Hubo un total de 668 pacientes (5,4%) con displasia de bajo grado, 76 pacientes (0,62%) con displasia de alto grado y 68 pacientes (0,55%) con adenocarcinoma en la serie. La tasa de incidencia acumulada de 1, 2, 5 anos de progresion de displasia de bajo grado a displasia de alto grado fue del 1,6%, 4,8% y 7,8%. Las tasas de incidencia acumulada de 1 y 2 anos de progresion de displasia de bajo grado a adenocarcinoma fueron 0,7% y 1,6%, respectivamente. No hubo diferencias significativas en la progresion unifocal y multifocal. Se encontro que la colangitis esclerosante primaria, la colitis ulcerosa, el sexo masculino y la edad avanzada eran factores de riesgo significativos de neoplasia en el analisis multivariable.LIMITACIONES:Base de datos retrospectiva.CONCLUSION:La progresion de la displasia de bajo grado a adenocarcinoma, independientemente de que sea unifocal o multifocal, sigue siendo muy baja en el contexto de una vigilancia y un tratamiento medico adecuados. La presencia de displasia multifocal de bajo grado no deberia cambiar la toma de decision para continuar con vigilancia endoscopica continua o realizar la proctocolectomia. Los pacientes con colangitis esclerosante primaria y displasia encontrada en biopsias aleatorias pueden tener una mayor progresion de la displasia.

Post-fundoplication dyspepsia is a common complication of gastric fundoplication surgeries. This can be attributable to the loss of fundal relaxation, decreased gastric accommodation, and/or alterations in gastric motility and sensitivity following fundoplication. The role of neuromodulators in the management of such symptoms is unknown. We retrospectively assessed the efficacy of neuromodulators such as tricyclic antidepressants, buspirone, and mirtazapine for the management of post-fundoplication dyspepsia.

No long-term pouch studies have included follow-up30 years or an analysis in patients80 years old.This study aimed to investigate pouch function and pouch failure in patients with a pouch in situ30 years and in patients80 years old.This is a retrospective review.This study was conducted at an IBD referral center.Adult patients with ulcerative colitis who underwent an IPAA between 1983 and 1990 were selected.The primary outcomes measured were pouch function and pouch failure rates.Data collection included diagnosis, age at IPAA, indication for IPAA, medications at IPAA, pathology at the time of IPAA, postoperative morbidity, functional outcomes, quality of life, pouch excision or ileostomy and indication, and date of last follow-up. All living patients were contacted in April 2020 to retrieve functional data and pouch failure rates.A total of 566 patients had a pouch constructed between 1983 and 1990; of the 145 at most recent contact, 75 had their pouch in situ ≥30 years and 14 were ≥80 years old. Mean age at diagnosis was 25.8 years (10.6 SD), age at surgery was 34.7 years (11.3 SD), and age at last follow-up was 60.5 years (13.2 SD). At a median of 30 years (IQR, 21-32), 145 patients responded to the functional survey. Significantly increased rates of urgency (always, mostly, sometimes: 71.5% vs 23.5%) and seepage during the day (71.4% vs 22.4%) were observed in patients ≥80 years. In patients ≥80 years with a pouch in situ ≥30 years, urgency and incontinence were sometimes experienced by nearly 50% and pouch failure occurred in one third of patients. The overall rate of pouch failure was 19.4% (n = 110) at a median follow-up of 15 years; risk factors were female sex, 3-stage approach, and pelvic sepsis.A retrospective database was used.Patients with IPAA maintain good pouch function even after 30 years and in patients over the age of 80 years. Pouch function declines with time and failure rates increase over time.

Se contactaron a todos los pacientes vivos en abril de 202 para recuperar la información de los índices de funcionalidad o disfunción de la bolsa.Se les construyó una bolsa a un total de 566 pacientes entre 1983 y 1990; de los 145 mas recientemente contactados, 75 permanecían con su bolsa in situ ≥ 30 años y 14 eran mayores de 80 años. La edad media en el momento de diagnóstico fue de 25.8 años (con desviación estándar de 10.6, sd), edad al momento de la cirugía fue de 34.7 años (11.3sd), y la edad en el último seguimiento de 60.5 años (13.2,sd). A una media de 30 años (IQR: 21,32), 145 pacientes respondieron al cuestionario de funcionalidad. En pacientes mayores de 80 años se observaron tasas aumentadas de urgencia (siempre, la mayor parte de las veces, algunas veces: 71.5% vs 23.5%) y fuga durante el día (71.4% versus 22.4%). En pacientes mayores de 80 años con una bolsa in situ durante 30 años o más, experimentaron urgencia e incontinencia en cerca del 50% y disfunción de la bolsa en un tercio de los pacientes. La tasa global de fallo de la bolsa fue de 19.4% (n = 110) en un seguimiento a 15 años; los factores de riesgo asociados fueron: sexo femenino, abordaje de tres tiempos y sepsis pélvica.Información retrospective.Los pacientes con IPAA continúan con una función adecuada de la bolsa aún después de 30 años de efectuada así como en pacientes mayores de 80 años. La funcionalidad de la bolsa disminuye con el tiempo y las tasa de falla aumentan de igual forma con el tiempo. Consulte Video Resumen en http://links.lww.com/DCR/B684.

BACKGROUND Anal squamous cell carcinoma has rarely been reported in the setting of ulcerative colitis. OBJECTIVE This study aimed to understand the prognosis of anal squamous cell carcinoma in the setting of ulcerative colitis. DESIGN This is a retrospective review. SETTING This study was conducted at a referral center. PATIENTS Adult patients with both ulcerative colitis (556.9/K51.9) and anal squamous cell carcinoma (154.3/C44.520) between January 1, 2000 and August 1, 2019 were included. MAIN OUTCOMES MEASURES The primary outcomes measured are treatment and survival of anal squamous cell carcinoma. RESULTS Of the 13,499 patients with ulcerative colitis treated, 17 adult patients with ulcerative colitis and anal dysplasia and/or anal squamous cell carcinoma were included in the study: 6 had a diagnosis of anal squamous cell carcinoma, 8 had high-grade squamous intraepithelial lesions, and 3 had low-grade squamous intraepithelial lesions. There were 4 men (23%) and a median age of 55 years (range, 32-69) years. At diagnosis, 6 had an IPAA, of which 5 had active pouchitis, 1 had an ileorectal anastomosis with active proctitis, 1 had a Hartmann stump with disuse proctitis, 5 had pancolitis, and 4 had left-sided colitis. Of the 6 with anal squamous cell carcinoma, all received 5-fluorouracil and mitomycin C with external beam radiation therapy. Four patients had an IPAA, all of whom required intestinal diversion or pouch excision because of treatment intolerance. At a median follow-up of 60 months, 3 patients died: one at 0 months (treatment-related myocardial infarction), one at 60 months (metastatic anal squamous cell carcinoma), and one at 129 months (malignant peripheral nerve sheath tumor); the remaining patients had no residual disease. LIMITATIONS This study was limited because of its retrospective nature and small number of patients. CONCLUSION Anal squamous cell carcinoma in the setting of ulcerative colitis is extremely rare. In the setting of IPAA, diversion may be necessary to prevent radiation intolerance. Careful examination of the perianal region should be performed at the time of surveillance endoscopy.

Background The effects of varying levels of pre-operative opioids on post-operative outcomes following elective laparoscopic cholecystectomy is largely unknown. Methods Patients who underwent elective laparoscopic cholecystectomy from 2012 to 2019 were reviewed and categorized by the number of outpatient opioid prescriptions received in the 90 days preceding surgery: none (Naive), one (1 Rx), two (2 Rx), or three or more (Chronic). Operative time, hospital length of stay, and 30-day readmission rate were analyzed. Results Of the 11911 patients identified, 2958 (24.8%) used opioids pre-operatively. Among patients with an overnight admission, the Naive, 1 Rx, and 2 Rx cohorts had a shorter length of stay compared to the Chronic cohort. The Naive group had the lowest 30-day readmission rate (5.0%) followed by the 1 Rx (5.9%), 2 Rx and Chronic groups (9.1% and 8.7%, respectively) (p Conclusions Prevalence of pre-operative opioid use is high and warrants surgeon assessment to minimize adverse post-operative outcomes.

Background Fecal diversion with an ileostomy is selectively used in cases of medically refractory Crohn’s proctocolitis or advanced perianal disease. The aim of this study was to evaluate clinical improvement after fecal diversion in Crohn’s disease (CD) and factors associated with clinical improvement. Methods A retrospective chart review of adult CD patients undergoing ileostomy formation for distal disease between 2000 and 2019 at 2 CD referral centers was conducted. The primary outcome was the rate of clinical improvement with diversion that allowed for successful restoration of intestinal continuity. Secondary outcomes included the rate of clinical and endoscopic improvement after fecal diversion, ileostomy morbidity, need for subsequent total proctocolectomy and end ileostomy, and factors associated with a clinical response to fecal diversion. Results A total of 132 patients with a median age of 36 years (interquartile range, 25–49) were included. Mean duration of disease was 16.2 years (10.4) years. Indication for surgery was medically refractory proctocolitis with perianal disease (n = 59; 45%), perianal disease alone (n = 24; 18%), colitis (n = 37; 28%), proctitis (n = 4; 3%), proctocolitis alone (n = 4; 3%), and ileitis with perianal disease (n = 4; 3%). Medications used before surgery included corticosteroids (n = 59; 45%), immunomodulators (n = 55; 42%) and biologics (n = 82; 62%). The clinical and endoscopic response to diversion was 43.2% (n = 57) and 23.9% (n = 16). At a median follow-up of 35.3 months (interquartile range, 10.6–74.5), 25 patients (19%) had improved and had ileostomy reversal, but 86 (65%) did not improve, with 50 (38%) undergoing total proctocolectomy for persistent symptoms. There were no significant predictors of clinical improvement. Conclusions The use of a “temporary” ileostomy is largely ineffective in achieving clinical response.

BACKGROUND Chemotherapy for pancreatic adenocarcinoma (PDAC) has significantly improved in recent years. While the involvement of the hepatic artery lymph node (HALN; station 8a lymph node) likely represents advanced disease, a comparison to patients with metastases on modern chemotherapy is lacking. METHODS Patients who underwent pancreatoduodenectomy with HALN sent for pathologic review at a single institution from 2003 to 2018 were reviewed. Patients who presented with liver-only metastases at the time of PDAC diagnosis (Stage IV) and received chemotherapy were identified. Multivariate Cox proportional hazards regression modeling was utilized and overall survival (OS) was estimated using Kaplan-Meier analysis. RESULTS Of the 112 patients with a HALN sent for analysis, 17 (15%) were positive and 13 (76%) received chemotherapy. Ninety-four stage IV patients were identified and were significantly more likely to have received a multiagent rather than single-agent chemotherapy regimen compared to HALN positive patients (79.8% vs. 38.5%, p

Gallbladder adenocarcinoma has a poor prognosis as it is often diagnosed incidentally, and patients have a high risk for residual and occult metastatic disease. Expert guidelines recommend definitive surgery for ≥T1b tumors; however, surgical management is inconsistent. This study evaluates the factors that affect the completion of radical resection with portal lymphadenectomy and its impact on survival. A retrospective review of patients who underwent surgery for gallbladder cancer from 2008 to 2017 at an academic institution was performed. Patients were analyzed based on whether they underwent definitive surgical resection. Patient factors and clinical decision-making were analyzed; overall survival was compared using Kaplan-Meier analysis. Seventy-five patients with ≥T1b tumors were identified, of who 32 (42.7%) underwent definitive resection. Fifty-four (72%) patients had gallbladder cancer identified as an incidental diagnosis following laparoscopic cholecystectomy. Among patients who did not undergo definitive resection, the underlying factors were varied. Only 24 (55.8%) patients in the non-definitive resection group were seen by surgical oncology. Among patients who underwent re-operation for definitive resection, 12 (38.7%) were upstaged on final pathology. Of the 43 patients who did not undergo definitive resection, 4 (9.3%) had metastatic disease identified during attempted re-resection. Patients who underwent definitive resection had a significantly longer median overall survival compared to those who did not (4.3 v. 1.9 years, p = 0.02). Patients undergoing definitive resection have a significantly improved survival, including as part of a re-operative strategy. Universal referral to a surgical specialist is a modifiable factor resulting in increased definitive resection rates.

Severe acute respiratory syndrome coronavirus 2 (SARS coronavirus 2, or SARS-CoV-2) is the cause of the respiratory infection known as COVID-19. From an immunopathological standpoint, coronaviruses such as SARS-CoV-2 induce increased levels of a variety of T-helper 1 (Th1) and inflammatory cytokines and chemokines, including interleukin-1 (IL-1), IL-6, CCL2 protein, and CXCL10 protein. In the absence of proven antiviral agents or an effective vaccine, substances with immunomodulatory activity may be able to inhibit inflammatory and Th1 cytokines and/or yield an anti-inflammatory and/or Th2 immune response to counteract COVID-19 symptoms and severity., Severe acute respiratory syndrome coronavirus 2 (SARS coronavirus 2, or SARS-CoV-2) is the cause of the respiratory infection known as COVID-19.

This report briefly describes the following four unconventional but commercially accessible immunomodulatory agents that can be employed in clinical trials to evaluate their effectiveness at alleviating disease symptoms and severity: low-dose oral interferon alpha, microdose DNA, low-dose thimerosal, and phytocannabinoids.

Summary Barrett’s esophagus (BE), a consequence of gastroesophageal reflux disease (GERD), is a premalignant condition for esophageal adenocarcinoma. Impaired gastric emptying leads to increased gastric volume and therefore more severe reflux. We seek to investigate the association between gastroparesis and BE and the predictors of BE among patients with gastroparesis. This is a retrospective review of patients seen at Cleveland Clinic between 2011 and 2016 who had an upper endoscopy and a gastric emptying study. Demographics, symptoms, medications, endoscopic and histological findings, and therapeutic interventions were abstracted. Risk of BE among gastroparesis group and control group was assessed, and logistic regression analysis was performed to identify predictors of BE among gastroparesis patients. Of the 4,154 patients, 864 (20.8%) had gastroparesis and 3, 290 (79.2%) had normal gastric emptying. The mean age was 51.4 ± 16.4 years, 72% were women and 80% were Caucasians. Among the gastroparesis group, 18 (2.1%) patients had BE compared to 71 (2.2%) cases of BE in the control group, P = 0.89. There were no differences in gender, race, reflux symptoms, or esophageal findings between the two groups. Among gastroparesis group, predictors of developing BE were a history of alcohol use (odds ratio [OR] 6.76; 95% confidence intervals [CI]: 1.65–27.67, P = 0.008), history of pyloroplasty (OR: 8.228; CI: 2.114–32.016, P = 0.002), and hiatal hernia (OR: 8.014; CI: 2.053–31.277, P = 0.003). Though gastroparesis is a known contributing factor for GERD, there was no increased prevalence of BE in gastroparesis. Among patients with gastroparesis, predictors of BE are history of alcohol use, hiatal hernia, and pyloroplasty.

BACKGROUND: Inadequate bowel preparation (IBP) is associated with reduced adenoma detection. However, limited research has examined the impact of different commercial bowel preparations (CBPs) on IBP and adenoma detection. We aim to determine whether type of CBP used is associated with IBP or adenoma detection. METHODS: We retrospectively evaluated outpatient, screening or surveillance colonoscopies performed in the Cleveland Clinic health system between January 2011 and June 2017. IBP was defined by the Aronchick scale. Multilevel mixed-effects logistic regression was performed to assess the association between CBP type and IBP and adenoma detection. Fixed effects were defined as demographics, comorbidities, medication use, and colonoscopy factors. Random effect of individual endoscopist was considered. RESULTS: Of 153,639 colonoscopies, 75,874 records met inclusion criteria. Median age was 54; 50% were female; 17.7% had IBP, and adenoma detection rate was 32.6%. In adjusted analyses, compared to GoLYTELY, only NuLYTELY [OR 0.66 (95% CI 0.60, 0.72)] and SuPREP [OR 0.53 (95% CI 0.40, 0.69)] were associated with reduced IBP. Adenoma detection did not vary based on the type of bowel preparation used. CONCLUSIONS: Among patients referred for screening or surveillance colonoscopy, choice of CBP was not associated with adenoma detection. Decisions about CBP should be based on other factors, such as tolerability, cost, or safety.

Energy healing is a therapy said to manipulate and balance the flow of “energies” in the body. One such technique, the Bengston Healing Method (BHM), has shown some success in healing malignant tumors in animals and humans, but the mechanism of action and factors influencing therapeutic success of this method are poorly understood. In this study, we tested in vivo the antitumor potential of magnetic signals recorded during BHM healing. Balb/c mice engrafted with 4T1 breast cancer cells were exposed to this recording for 4 h/d on a weekly or daily basis for 28 days; control mice were not exposed at all. Tumors showed a trend to grow slower in the treatment versus control group during the fourth week of treatment. Elevated leukocyte counts, associated with an increase in blood levels of granulocyte–macrophage colony stimulating factor and interleukin-6, were observed in tumor-bearing mice exposed to the BHM recording but not in healthy animals exposed to the recording. This suggests that exposure to a recording of BHM may induce a biological response in tumor-bearing mice, but limited effects on tumor growth when observed within the predefined end point of 28 days. Studies involving longer end points are recommended to observe the progression of tumor growth.

Background and Aims Serrated polyposis syndrome (SPS) is common but under-recognized and is associated with an increased risk of colorectal cancer. The diagnosis is based on the World Health Organization (WHO) criteria and is inclusive of the cumulative number of lifetime serrated polyps. We used natural language processing (NLP) to extract colonoscopy and pathology data from the electronic medical record (EMR). The aim of this study was to assess feasibility of using an NLP-based SPS tool to identify patients with SPS. Methods NLP was used to extract data from 323,494 colonoscopies performed in 255,074 distinct patients between August 1998 and March 2016 to identify individuals who met SPS criteria. The accuracy of diagnosis of SPS was assessed by manual review of the EMR. Results Of 255,074 patients, 71 were identified as meeting 1 WHO criteria for SPS. Manual review confirmed the diagnosis of SPS to be accurate in 66 cases (93%). Erroneous diagnosis in the remaining 5 cases occurred because of duplicate polyp data by NLP extraction. Only 25 of 66 patients (38%) were diagnosed with SPS by a clinician in the EMR. Of these, SPS was diagnosed by NLP at least 2 years before the clinician in 5 of 25 patients (20%). Conclusions In a large cohort, NLP accurately identified SPS in over 90% of cases, most of which were not previously recognized. NLP can assist in collating colonoscopy and pathology data across multiple procedures in the same patient to make an accurate and earlier diagnosis of SPS.
