Abstract
BACKGROUND AND AIMS Performing a high-quality colonoscopy is critical for optimizing the adenoma detection rate (ADR). Colonoscopy withdrawal time (a surrogate measure) of ≥6 minutes is recommended; however, a threshold of a high-quality withdrawal and its impact on ADR are not known. METHODS We examined withdrawal time (excluding polyp resection and bowel cleaning time) of subjects undergoing screening and/or surveillance colonoscopy in a prospective, multicenter, randomized controlled trial. We examined the relationship of withdrawal time in 1-minute increments on ADR and reported odds ratio (OR) with 95% confidence intervals. Linear regression analysis was performed to assess the maximal inspection time threshold that impacts the ADR. RESULTS A total of 1142 subjects (age, 62.3 ± 8.9 years; 80.5% men) underwent screening (45.9%) or surveillance (53.6%) colonoscopy. The screening group had a median withdrawal time of 9.0 minutes (interquartile range [IQR], 3.3) with an ADR of 49.6%, whereas the surveillance group had a median withdrawal time of 9.3 minutes (IQR, 4.3) with an ADR of 63.9%. ADR correspondingly increased for a withdrawal time of 6 minutes to 13 minutes, beyond which ADR did not increase (50.4% vs 76.6%, P < .01). For every 1-minute increase in withdrawal time, there was 6% higher odds of detecting an additional subject with an adenoma (OR, 1.06; 95% confidence interval, 1.02-1.10; P = .004). CONCLUSIONS Results from this multicenter, randomized controlled trial underscore the importance of a high-quality examination and efforts required to achieve this with an incremental yield in ADR based on withdrawal time.

Abstract
There are limited data on the safety of same-day discharge (SDD) after peroral endoscopic myotomy (POEM). The aim of our study is to assess the frequency and relationship to POEM for emergency department (ED) visits and hospitalizations after SDD in these patients. We retrospectively identified consecutive patients between November 2019 and August 2021 who underwent POEM with SDD and at least 6 months follow-up. Criteria for SDD includes: (1) no serious procedure-related adverse event; (2) post-POEM esophagram without leak; (3) stable vital signs; (4) ability to take liquids orally; (5) pain controlled without IV analgesia; (6) adequate social support; (7) American Society of Anesthesiologists (ASA) class I-III. A causative relationship between POEM and ED visits and hospitalizations was assigned by consensus. Out of 185 POEMs performed, 78 (41.7%, 42M, mean 51±16 years) had SDD. Within 30 days of POEM, 8 ED visits occurred in 7/78 (9%) patients and 2 (25%) were considered related to POEM; hospitalization was required in 3 (38%). After 30 days, 11 ED visits occurred in 10/78 (12.8%) patients and 1 (9%) was considered related to POEM; hospitalization was required in 5 (45%). In this study of consecutive SDD patients after POEM, 3/19 (16%) ED visits and 2/8 (25%) hospitalizations within 6 months were considered related to the procedure. Therefore, eligible patients who follow and fulfill a strict protocol after POEM may be safely discharged the same day.

Abstract
Background and study aims The aim of this study was to evaluate whether timed barium esophagram within 24 hours post-per-oral endoscopic myotomy (POEM) (TBE-PP) could predict clinical outcomes. Patients and methods This was a single-center retrospective study of prospectively collected data on consecutive patients with ≥ 6-month follow-up who underwent POEM followed by TBE-PP. Esophageal contrast retention 2 minutes after TBE-PP was assessed as Grade 1 (< 10 %), 2 (10 %-49 %), 3 (50 %-89 %) or 4 (> 90 %). Eckardt score, esophagogastroduodenoscopy (EGD), high-resolution manometry (HRM) and function lumen imaging probe (FLIP) of the esophagogastric junction (EGJ) were obtained at baseline. These tests along with pH testing of antisecretory therapy were repeated 6 and 24 months after POEM. Clinical response by Eckardt score ≤ 3, EGJ-distensibility index (EGJ-DI) > 2.8 mm 2 /mm Hg, and integrated relaxation pressure (IRP) < 15 mm Hg and incidence of gastroesophageal reflux disease (GERD) were compared by transit time. Results Of 181 patients (58 % male, mean 53 ± 17 yr), TBE-PP was classified as Grade 1 in 122 (67.4 %), Grade 2 in 41 (22.7 %), Grade 3 in 14 (7.7 %) and Grade 4 in 4 (2.2 %). At 6 months, overall clinical response by ES (91.7 %), IRP (86.6 %), EGJ-DI (95.7 %) and the diagnosis of GERD (68.6 %) was similar between Grade 1 and Grade 2-4 TBE-PP. At 24 months, Grade 1 had a higher frequency of a normal IRP compared to Grades 2-4 (95.7 % vs. 60 %, P = 0.021) but overall response by ES (91.2 %), EGJ-DI (92.3 %) and the diagnosis of GERD (74.3 %) were similar. Conclusions Contrast emptying rate by esophagram after POEM has limited utility to predict clinical response or risk of post-procedure GERD.

Abstract
OBJECTIVES Celiac disease (CD) is commonly found in women. Given the sex differences in diagnosed patients, we hypothesized sex differences in physicians obtaining biopsies for CD may exist. MATERIALS AND METHODS We retrospectively reviewed duodenal biopsies for suspected CD excluding pre-existing CD patients. Appropriate biopsy practice was defined as ≥5 specimens per ACG guidelines. RESULTS We included 125 patients (females, 92). There were 85 properly (68%) biopsied. Presence of a female endoscopist was associated with better adherence to biopsy guidelines (OR, 2.99, 95% CI, 1.19-7.54; p = .02) which remained significant after multivariable adjustment (adjusted OR, 2.7; p = .047). CONCLUSIONS Physician sex-based differences in biopsy patterns may exist.

Abstract
BACKGROUND AND AIMS Endocuff (Arc Medical Design, Leeds, UK) and Endocuff Vision (Arc Medical Design, Leeds, UK) are effective mucosal exposure devices for improving polyp detection during colonoscopy. AmplifEYE (Medivators Inc, Minneapolis, Minn, USA) is a device that appears similar to the Endocuff devices but has received minimal clinical testing. METHODS We performed a randomized controlled clinical trial using a noninferiority design to compare Endocuff Vision with AmplifEYE. RESULTS The primary endpoint of adenomas per colonoscopy was similar in AmplifEYE at 1.63 (standard deviation 2.83) versus 1.51 (2.29) with Endocuff Vision (P = .535). The 95% lower confidence limit was 0.88 for ratio of means, establishing noninferiority of AmplifEYE (P = .008). There was no difference between the arms for mean insertion time, and mean inspection time (withdrawal time minus polypectomy time and time for washing and suctioning) was shorter with AmplifEYE (6.8 minutes vs 6.9 minutes, P = .042). CONCLUSIONS AmplifEYE is noninferior to Endocuff Vision for adenoma detection. The decision on which device to use can be based on cost. Additional comparisons of AmplifEYE with Endocuff by other investigators are warranted. (Clinical trial registration number: NCT03560128.).

Abstract
BACKGROUND AND AIMS Self-expanding metal stents (SEMSs) when deployed across the gastroesophageal junction (GEJ) can lead to reflux with risks of aspiration. A SEMS with a tricuspid antireflux valve (SEMS-V) was designed to address this issue. The aim of this study was to evaluate the efficacy and safety of this stent. METHODS A phase III, multicenter, prospective, noninferiority, randomized controlled trial was conducted on patients with malignant dysphagia requiring SEMSs to be placed across the GEJ. Patients were randomized to receive SEMSs with no valve (SEMS-NV) or SEMS-V. Postdeployment dysphagia score at 2 weeks and Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) questionnaire score at 4 weeks were measured. Patients were followed for 24 weeks. RESULTS Sixty patients were randomized (SEMS-NV: 30 patients, mean age 67 ± 13 years; SEMS-V: 30 patients, mean age 65 ± 12 years). Baseline dysphagia scores (SEMS-NV, 2.5 ± .8; SEMS-V, 2.5 ± .8) and GERD-HRQL scores (SEMS-NV, 11.1 ± 8.2; SEMS-V, 12.8 ± 8.3) were similar. All SEMSs were successfully deployed. A similar proportion of patients in both arms improved from advanced dysphagia to moderate to no dysphagia (SEMS-NV, 71%; SEMS-V, 74%; 95% confidence interval, 1.93 [-17.8 to 21.7]). The dysphagia scores were also similar across all follow-up time points. Mean GERD-HRQL scores improved by 7.4 ± 10.2 points in the SEMS-V arm and by 5.2 ± 8.3 in the SEMS-NV group (P = .96). The GERD-HRQL scores were similar across all follow-up time points. Aspiration pneumonia occurred in 3.3% in the SEMS-NV arm and 6.9% in the SEMS-V arm (P = .61). Migration rates were similar (SEMS-NV, 33%; SEMS-V, 48%; P = .29). Two SEMS-V spontaneously fractured. There was no perforation, food impaction, or stent-related death in either group. CONCLUSIONS The SEMS-V was equally effective in relieving dysphagia as compared with the SEMS-NV. Presence of the valve did not increase the risks of adverse events. GERD symptom scores were similar between the 2 stents, implying either that the valve was not effective or that all patients on proton pump inhibitors could have masked the symptoms of GERD. Studies with objective evaluations such as fluoroscopy and/or pH/impedance are recommended. (Clinical trial registration number: NCT02159898.).

Abstract
Background and aims The impact of the advent of an institutional endoscopic eradication therapy (EET) program on surgical practice for Barrett's esophagus (BE)-associated high grade dysplasia (HGD) or suspected T1a esophageal adenocarcinoma (EAC) is unknown. The aims of this study are to evaluate the different endoscopic modalities used during development of our EET program and factors associated with the use of EET or surgery for these patients after its development. Methods Patients who underwent primary endoscopic or surgical treatment for BE-HGD or early EAC at our hospital between January 1992 and December 2014 were retrospectively identified. They were categorized by their initial modality of treatment during the first year, and the impact over time for choice of therapy was assessed by multivariable logistic regression. Results We identified 386 patients and 80 patients who underwent EET and surgery, respectively. EET included single modality therapy in 254 (66 %) patients and multimodal therapy in 132 (34 %) patients. Multivariable logistic regression showed that, for each subsequent study year, EET was more likely to be performed in patients who were older ( P = 0.0009), with shorter BE lengths ( P < 0.0001), and with a pretreatment diagnosis of HGD ( P = 0.0054) compared to surgical patients. The diagnosis of EAC did not increase the utilization of EET compared to surgery as time progressed ( P = 0.8165). Conclusion The introduction of an EET program at our hospital increased the odds of utilizing EET versus surgery over time for initial treatment of patients who were older, had shorter BE lengths or the diagnosis of BE-HGD, but not in patients with EAC.

Abstract
BACKGROUND Level 1 programs have improved outcomes by expediting the multidisciplinary care of critically ill patients. We established a novel level 1 program for the management of esophageal emergencies. METHODS After institutional review board approval, we performed a retrospective analysis of patients referred to our level 1 esophageal emergency program from April 2013 through November 2015. A historical comparison group of patients treated for the same diagnosis in the previous 2 years was used. RESULTS Eighty patients were referred and transported an average distance of 56 miles (range, 1-163 miles). Median time from referral to arrival was 2.4 hours (range, 0.4-12.9 hours). Referrals included 6 (7%) patients with esophageal obstruction and 71 (89%) patients with suspected esophageal perforation. Of the patients with suspected esophageal perforation, causes included iatrogenic (n = 26), Boerhaave's syndrome (n = 32), and other (n = 13). Forty-six percent (n = 33) of patients were referred because of pneumomediastinum, but perforation could not be subsequently demonstrated. Initial management of patients with documented esophageal perforation included operative treatment (n = 25), endoscopic intervention (n = 8), and supportive care (n = 5). Retrospective analysis demonstrated a statistically significant difference in mean Pittsburgh severity index score (PSS) between esophageal perforation treatment groups (p < 0.01). In patients with confirmed perforations, there were 3 (8%) mortalities within 30 days. More patients in the esophageal level 1 program were transferred to our institution in less than 24 hours after diagnosis than in the historical comparison group (p < 0.01). CONCLUSIONS Development of an esophageal emergency referral program has facilitated multidisciplinary care at a high-volume institution, and early outcomes appear favorable.

Abstract
BACKGROUND The value of narrow-band imaging (NBI) for detecting serrated lesions is unknown. OBJECTIVE To assess NBI for the detection of proximal colon serrated lesions. DESIGN Randomized, controlled trial. SETTING Two academic hospital outpatient units. PATIENTS Eight hundred outpatients 50 years of age and older with intact colons undergoing routine screening, surveillance, or diagnostic examinations. INTERVENTIONS Randomization to colon inspection in NBI versus white-light colonoscopy. MAIN OUTCOME MEASUREMENTS The number of serrated lesions (sessile serrated polyps plus hyperplastic polyps) proximal to the sigmoid colon. RESULTS The mean inspection times for the whole colon and proximal colon were the same for the NBI and white-light groups. There were 204 proximal colon lesions in the NBI group and 158 in the white light group (P = .085). Detection of conventional adenomas was comparable in the 2 groups. LIMITATIONS Lack of blinding, endoscopic estimation of polyp location. CONCLUSION NBI may increase the detection of proximal colon serrated lesions, but the result in this trial did not reach significance. Additional study of this issue is warranted.

Abstract
BACKGROUND Both long-term proton pump inhibitor (PPI) use and surgical fundoplication have potential drawbacks as treatments for chronic gastroesophageal reflux disease (GERD). This multi-center, prospective study evaluated the clinical experiences of 69 patients who received an alternative treatment: endoscopic anterior fundoplication with a video- and ultrasound-guided transoral surgical stapler. METHODS Patients with well-categorized GERD were enrolled at six international sites. Efficacy data was compared at baseline and at 6 months post-procedure. The primary endpoint was a ≥ 50 % improvement in GERD health-related quality of life (HRQL) score. Secondary endpoints were elimination or ≥ 50 % reduction in dose of PPI medication and reduction of total acid exposure on esophageal pH probe monitoring. A safety evaluation was performed at time 0 and weeks 1, 4, 12, and 6 months. RESULTS 66 patients completed follow-up. Six months after the procedure, the GERD-HRQL score improved by >50 % off PPI in 73 % (48/66) of patients (95 % CI 60-83 %). Forty-two patients (64.6 %) were no longer using daily PPI medication. Of the 23 patients who continued to take PPI following the procedure, 13 (56.5 %) reported a ≥ 50 % reduction in dose. The mean percent of total time with esophageal pH <4.0 decreased from baseline to 6 months (P < 0.001). Common adverse events were peri-operative chest discomfort and sore throat. Two severe adverse events requiring intervention occurred in the first 24 subjects, no further esophageal injury or leaks were reported in the remaining 48 enrolled subjects. CONCLUSIONS The initial 6-month data reported in this study demonstrate safety and efficacy of this endoscopic plication device. Early experience with the device necessitated procedure and device changes to improve safety, with improved results in the later portion of the study. Continued assessment of durability and safety are ongoing in a three-year follow-up study of this patient group.

Abstract
BACKGROUND Factors associated with successful endoscopic therapy with temporary stents for esophageal leaks, fistulae, and perforations (L/F/P) are not well known. OBJECTIVES To evaluate the safety, efficacy, and outcomes of esophageal stenting in these patients and identify factors associated with successful closure. DESIGN Retrospective. SETTING Academic tertiary referral center. PATIENTS All patients with attempted stent placement for esophageal L/F/P between January 2003 and May 2012. INTERVENTION Esophageal stent placement and removal. MAIN OUTCOME MEASUREMENTS Factors predictive of therapeutic success defined as complete closure after index stent removal (primary closure) or after further endoscopic stenting (secondary closure). RESULTS Sixty-seven patients with 132 attempted stents for esophageal L/F/P were considered; 13 patients were excluded. Among the remaining 54 patients, 117 stents were placed for leaks (29 patients; 64 stents), fistulae (15 patients; 36 stents), and perforations (10 patients; 17 stents). Procedural technical success was achieved in all patients (100%). Primary closure was successful in 40 patients (74%) and secondary closure in an additional 5 (83% overall). On short-term (<3 months) follow-up, 27 patients (50%) were asymptomatic, whereas 22 (41%) had technical adverse events, including stent migration in 15 patients (28%). Factors associated with successful primary closure include a shorter time between diagnosis of esophageal L/F/P and initial stent insertion (9.03 vs 22.54 days; P = .003), and a smaller luminal opening size (P = .002). LIMITATIONS Retrospective, single-center study. CONCLUSIONS Temporary stents are safe and effective in treating esophageal L/F/P. Defect opening size and time from diagnosis to stent placement appear to be candidate predictors for successful closure.

Abstract
BACKGROUND AND AIMS Endoscopic prediction of polyp histology is rapidly improving to the point where it may not be necessary to submit all polyps for formal histologic assessment. This study aimed to quantify the expected costs and outcomes of removing diminutive polyps without subsequent pathologic assessment. METHODS Cross-sectional analysis of a colonoscopy database for polyp histology; decision models that quantify effects on guideline-recommended surveillance and subsequent costs and consequences. The database was composed of consecutive colonoscopies from 1999 to 2004 at a single-institution tertiary care center. Patients were those found to have at least one diminutive polyp removed during colonoscopy, irrespective of indication. The main outcome measurements include up-front cost savings resulting from forgoing pathologic assessment; frequency and cost of incorrect surveillance intervals based on errors in histologic assessment; number needed to harm (NNH) for perforation and/or interval cancer. RESULTS Incorrect surveillance intervals were recommended in 1.9% of cases when tissue was submitted for pathologic assessment and 11.8% of cases when it was not. Based on the annual volume of colonoscopy in the US, the annual up-front cost savings of forgoing the pathologic assessment would exceed a billion dollars. An upper estimate on the downstream costs and consequences of forgoing pathology suggests that less than 10% of the up-front savings would be offset and the NNH exceeds 11000. CONCLUSION Endoscopic diagnosis of polyp histology during colonoscopy and forgoing pathologic examination would result in substantial up-front cost savings. Downstream consequences of the resulting incorrect surveillance intervals appear to be negligible.

Abstract
OBJECTIVES Flat and depressed colon neoplasms are an increasingly recognized precursor for colorectal cancer (CRC) in Western populations. High-definition chromoscopy is used to increase the yield of colonoscopy for flat and depressed neoplasms; however, its role in average-risk patients undergoing routine screening remains uncertain. METHODS Average-risk patients referred for screening colonoscopy at four U.S. medical centers were randomized to high-definition chromocolonoscopy or high-definition white light colonoscopy. The primary outcomes, patients with at least one adenoma and the number of adenomas per patient, were compared between the two groups. The secondary outcome was patients with flat or depressed neoplasms, as defined by the Paris classification. RESULTS A total of 660 patients were randomized (chromocolonoscopy: 321, white light: 339). Overall, the mean number of adenomas per patient was 1.2+/-2.1, the mean number of flat polyps per patient was 1.4+/-1.9, and the mean number of flat adenomas per patient was 0.5+/-1.0. The number of patients with at least one adenoma (55.5% vs. 48.4%, absolute difference 7.1%, 95% confidence interval (-0.5% to 14.7%), P=0.07), and the number of adenomas per patient (1.3+/-2.4 vs. 1.1+/-1.8, P=0.07) were marginally higher in the chromocolonoscopy group. There were no significant differences in the number of advanced adenomas per patient (0.06+/-0.37 vs. 0.04+/-0.25, P=0.3) and the number of advanced adenomas<10 mm per patient (0.02+/-0.26 vs. 0.01+/-0.14, P=0.4). Two invasive cancers were found, one in each group; neither was a flat neoplasm. Chromocolonoscopy detected significantly more flat adenomas per patient (0.6+/-1.2 vs. 0.4+/-0.9, P=0.01), adenomas<5 mm in diameter per patient (0.8+/-1.3 vs. 0.7+/-1.1, P=0.03), and non-neoplastic lesions per patient (1.8+/-2.3 vs. 1.0+/-1.3, P<0.0001). CONCLUSIONS High-definition chromocolonoscopy marginally increased overall adenoma detection, and yielded a modest increase in flat adenoma and small adenoma detection, compared with high-definition white light colonoscopy. The yield for advanced neoplasms was similar for the two methods. Our findings do not support the routine use of high-definition chromocolonoscopy for CRC screening in average-risk patients. The high adenoma detection rates observed in this study may be due to the high-definition technology used in both groups.

Abstract
BACKGROUND Colonoscopy may fail to detect neoplasia located on the proximal sides of haustral folds and flexures. The Third Eye Retroscope (TER) provides a simultaneous retrograde view that complements the forward view of a standard colonoscope. OBJECTIVE To evaluate the added benefit for polyp detection during colonoscopy of a retrograde-viewing device. DESIGN Open-label, prospective, multicenter study evaluating colonoscopy by using a TER in combination with a standard colonoscope. SETTING Eight U.S. sites, including university medical centers, ambulatory surgery centers, a community hospital, and a physician's office. PATIENTS A total of 249 patients (age range 55-80 years) presenting for screening or surveillance colonoscopy. INTERVENTIONS After cecal intubation, the disposable TER was inserted through the instrument channel of the colonoscope. During withdrawal, the forward and retrograde video images were observed simultaneously on a wide-screen monitor. MAIN OUTCOME MEASUREMENTS The number and sizes of lesions (adenomas and all polyps) detected with the standard colonoscope and the number and sizes of lesions found only because they were first detected with the TER. RESULTS In the 249 subjects, 257 polyps (including 136 adenomas) were identified with the colonoscope alone. The TER allowed detection of 34 additional polyps (a 13.2% increase; P < .0001) including 15 additional adenomas (an 11.0% increase; P < .0001). For lesions 6 mm or larger, the additional detection rates with the TER for all polyps and for adenomas were 18.2% and 25.0%, respectively. For lesions 10 mm or larger, the additional detection rates with the TER for all polyps and for adenomas were 30.8% and 33.3%, respectively. In 28 (11.2%) individuals, at least 1 additional polyp was found with the TER. In 8 (3.2%) patients, the polyp detected with the TER was the only one found. Every polyp that was detected with the TER was subsequently located with the colonoscope and removed. For all polyps and for adenomas, the additional detection rates for the TER were 9.7%/4.1% in the left colon (the splenic flexure to the rectum) and 16.5%/14.9% in the right colon (the cecum to the transverse colon), respectively. LIMITATIONS There was no randomization or comparison with a separate control group. CONCLUSIONS A retrograde-viewing device revealed areas that were hidden from the forward-viewing colonoscope and allowed detection of 13.2% additional polyps, including 11.0% additional adenomas. Additional detection rates with the TER for adenomas 6 mm or larger and 10 mm or larger were 25.0% and 33.3%, respectively. ( CLINICAL TRIAL REGISTRATION NUMBER NCT00657371.).

Abstract
BACKGROUND Colonoscopes with short bending sections facilitate retroflexion but their effect on other aspects of colonoscope insertion are unknown. We sought to determine the impact of short bending on cecal insertion, terminal ileal intubation, and proximal colon retroflexion. METHODS Two studies were performed. In study 1, we randomized 104 adult patients with intact colons to undergo colonoscopy with a standard pediatric colonoscope (Olympus PCF-160), a prototype pediatric colonoscope with short bending in four directions (PCF-AYL), or a prototype pediatric colonoscope with short bending in two directions, and normal bending in two directions (PCF-AY3L). In study 2, we randomized 70 patients with intact colons to undergo colonoscopy with a prototype 170 degrees wide angle colonoscope (CFQ160-WL) with a standard bending section length or to a prototype 170 degrees colonoscope with a short bending section (CFQ160-W2L). RESULTS In study 1, the cecum was reached in all patients. Using the AYL, the cecal intubation time (4.08 min) was significantly longer when compared to both the PCF-160 (2.62 min; p=0.0001) and the AY3L (3.25 min; p=0.02). The AYL required the application of abdominal pressure (79%) and activation of the variable stiffness device (70%) more frequently when compared to both the PCF-160 (32%; p=0.0001 and 41%; p=0.02, respectively) and the AY3L (34%; p=0.0003 and 41%; p=0.02, respectively). Successful cecal retroflexion was possible less often with the PCF-160 (57%) when compared to either the AYL (94%; p=0.005) or AY3L (91%; p=0.001). The ability to intubate the terminal ileum was similar in all three groups (PCF-160 and AY3L 100%; AYL 94%) as was the time needed to intubate (p=0.73). Depth of ti intubation was deeper for the PCF-160 when compared to the AYL (p=0.0002) or AY3L (p=0.02). There was a trend toward deeper ileal intubation with the AY3L compared to AYL (p=0.09). In study 2, no difference was noted in cecal intubation time (p=0.1) or in frequency of application of abdominal pressure (p=0.28), position change (p=0.15), or activation of the stiffening device (p=0.46). Cecal retroflexion was successful more often when using the W2L when compared to the WL (p=0.00001). CONCLUSION Short bending sections facilitate proximal colon retroflexion for both pediatric and adult colonoscopes, but can negatively impact cecal insertion and terminal ileal intubation in pediatric colonoscopes. A pediatric colonoscope with short bending in only two directions had good function for both cecal insertion and proximal colon retroflexion.

Abstract
BACKGROUND & AIMS Autoimmune hepatitis is a common cause of chronic hepatitis, and acute presentation is thought to be uncommon. The aim of this study was to compare clinical, biochemical, and histological features in patients with autoimmune hepatitis presenting with either acute or chronic hepatitis. METHODS Retrospective review of all patients with autoimmune hepatitis presenting to a University medical center from 1993 to 2002. RESULTS One hundred fifteen patients with autoimmune hepatitis were identified. Ten patients with autoimmune hepatitis were identified as having acute presentation (group I), and 20 patients with a classic presentation as chronic hepatitis (group II) served as age- and sex-matched controls. All patients met criteria published by the International Autoimmune Hepatitis Group. Patients with acute presentation differed significantly with regard to encephalopathy, albumin levels, and bilirubin levels. Blinded liver biopsy review demonstrated that those with acute presentation had significantly less fibrosis, and significantly greater interface hepatitis, lobular disarray, lobular hepatitis, hepatocyte necrosis, zone III necrosis, and submassive necrosis. CONCLUSIONS In our study, patients with an acute presentation of autoimmune hepatitis differed from patients with a classical presentation clinically, biochemically, and histologically. In our review, a majority of patients with acute autoimmune hepatitis presented with fulminant hepatic failure. The pattern of zone 3 necrosis may be a specific finding in those with acute autoimmune hepatitis.

In our review, a majority of patients with acute autoimmune hepatitis presented with fulminant hepatic failure. The pattern of zone 3 necrosis may be a specific finding in those with acute autoimmune hepatitis.
