RESUMO
BACKGROUND: An endoscopist's adenoma detection rate (ADR) is inversely related to interval colorectal cancer risk and cancer mortality. Previous studies evaluating the impact of gastroenterology fellow participation in colonoscopy on ADR have generated conflicting results. AIMS: We aimed to determine the impact of fellow participation, duration of fellowship training, and physician sex on ADR and advanced ADR (AADR). METHODS: We retrospectively analyzed average-risk patients undergoing screening colonoscopy at Veterans Affairs New York Harbor Healthcare System Brooklyn Campus and Kings County Hospital Center. Review of colonoscopy and pathology reports were performed to obtain adenoma-specific details, including the presence of advanced adenoma and adenoma location (right vs. left colon). RESULTS: There were 893 colonoscopies performed by attending only and 502 performed with fellow participation. Fellow participation improved overall ADR (44.6% vs. 35.4%, p < 0.001), right-sided ADR (34.1% vs. 25.2%, p < 0.001), and AADR (15.3% vs. 8.3%, p < 0.001); however, these findings were institution-specific. Year of fellowship training did not impact overall ADR or overall AADR, but did significantly improve right-sided AADR (p-value for trend 0.03). Female attending physicians were associated with increased ADR (47.1% vs. 37.0%, p = 0.0037). Fellow sex did not impact ADR. CONCLUSIONS: Fellow participation in colonoscopy improved overall ADR and AADR, and female attending physicians were associated with improved ADR. Year of fellowship training did not impact overall ADR or AADR.

BACKGROUND & AIMS: Endoscopic surveillance of patients with Barrett's esophagus (BE) is inefficient. Risk stratification of patients might improve the effectiveness of surveillance. We performed a systematic review and meta-analysis to identify factors associated with progression of BE without dysplasia or BE with low-grade dysplasia (LGD) to high-grade dysplasia or esophageal adenocarcinoma. METHODS: We performed a systematic search of databases through May 2016 to identify cohort studies of patients with baseline BE without dysplasia or BE with LGD that reported predictors of progression. Pooled estimates (odds ratios) of associations of age, sex, smoking, alcohol use, obesity, baseline LGD, segment length, and medication use with progression were calculated. RESULTS: We identified 20 studies, reporting 1231 events in 74943 patients. The studies associated BE progression with increasing age (12 studies; odds ratio [OR], 1.03; 95% CI, 1.01-1.05), male sex (11 studies; OR, 2.16; 95% CI, 1.84-2.53), ever smoking (current or past, 8 studies; OR, 1.47; 95% CI, 1.09-1.98), and increasing BE segment length (10 studies; OR, 1.25; 95% CI, 1.16-1.36), with a low degree of heterogeneity. LGD was associated with a 4-fold increase in risk of BE progression (11 studies; OR, 4.25; 95% CI, 2.58-7.0). Use of proton pump inhibitors (4 studies; OR, 0.55; 95% CI, 0.32-0.96) or statins (3 studies; OR, 0.48; 95% CI, 0.31-0.73) were associated with lower risk of BE progression. Alcohol use and obesity did not associate with risk of progression. CONCLUSIONS: In a systematic review and meta-analysis, we associated older age, male sex, smoking, longer BE segment, and LGD with risk of progression of BE. Individuals with these features should undergo more intensive surveillance or endoscopic therapy. Smoking is a modifiable risk factor for cancer prevention in patients with BE.

BACKGROUND AND AIMS: Previous estimates of incidence of intestinal metaplasia (IM) recurrence after achieving complete remission of IM (CRIM) through endoscopic therapy of Barrett's esophagus (BE) have varied widely. We performed a systematic review and meta-analysis of studies to estimate an accurate recurrence risk after CRIM. METHODS: We performed a systematic search of multiple literature databases through June 2015 to identify studies reporting long-term follow-up after achieving CRIM through endoscopic therapy. Pooled incidence rate (IR) of recurrent IM, dysplastic BE, and high-grade dysplasia (HGD)/esophageal adenocarcinoma (EAC) per person-year of follow-up after CRIM was estimated. Factors associated with recurrence were also assessed. RESULTS: We identified 41 studies that reported 795 cases of recurrence in 4443 patients over 10,427 patient-years of follow-up. This included 21 radiofrequency ablation studies that reported 603 cases of IM recurrence in 3186 patients over 5741 patient-years of follow-up. Pooled IRs of recurrent IM, dysplastic BE, and HGD/EAC after radiofrequency ablation were 9.5% (95% CI, 6.7-12.3), 2.0% (95% CI, 1.3-2.7), and 1.2% (95% CI, .8-1.6) per patient-year, respectively. When all endoscopic modalities were included, pooled IRs of recurrent IM, dysplastic BE, and HGD/EAC were 7.1% (95% CI, 5.6-8.6), 1.3% (95% CI, .8-1.7), and .8% (95% CI, .5-1.1) per patient-year, respectively. Substantial heterogeneity was noted. Increasing age and BE length were predictive of recurrence; 97% of recurrences were treated endoscopically. CONCLUSIONS: The incidence of recurrence after achieving CRIM through endoscopic therapy was substantial. A small minority of recurrences were dysplastic BE and HGD/EAC. Hence, continued surveillance after CRIM is imperative. Additional studies with long-term follow-up are needed.

BACKGROUND: The management of ascites can be problematic. This is especially true in patients with diuretic refractory ascites who develop a tense abdomen. This often results in hypotension and decreased venous return with resulting renal failure. In this paper, we further examine the risks and benefits of utilizing an indwelling peritoneal catheter to remove large-volume ascites over a 72-h period while maintaining intravascular volume and preventing renal failure. METHODS: We retrospectively reviewed charts and identified 36 consecutive patients undergoing continuous large-volume paracentesis with an indwelling peritoneal catheter. At the time of drain placement, no patients had signs or laboratory parameters suggestive of spontaneous bacterial peritonitis. The patients underwent ascitic fluid removal through an indwelling peritoneal catheter and were supported with scheduled albumin throughout the duration. The catheter was used to remove up to 3 L every 8 h for a maximum of 72 h. Regular laboratory and ascitic fluid testing was performed. All patients had a clinical follow-up within 3 months after the drain placement. RESULTS: An average of 16.5 L was removed over the 72-h time frame of indwelling peritoneal catheter maintenance. The albumin infusion utilized correlated to 12 mg/L removed. The average creatinine trend improved in a statistically significant manner from 1.37 on the day of admission to 1.21 on the day of drain removal. No patients developed renal failure during the hospital course. There were no documented episodes of neutrocytic ascites or bacterial peritonitis throughout the study review. CONCLUSION: Large-volume peritoneal drainage with an indwelling peritoneal catheter is safe and effective for patients with tense ascites. Concomitant albumin infusion allows for maintenance of renal function, and no increase in infectious complications was noted.
RESUMO
Annular pancreas is a rare congenital anomaly that has been often implicated in duodenal and biliary obstructions. However, the true incidence of such presentation is very low. We present a case of a 57-year-old female with mixed hepatocellular and obstructive jaundice where annular pancreas was an innocent bystander.
