Impact of changing diagnostic criteria on the diagnosis of serrated polyposis syndrome.

The World Health Organization criteria for serrated polyposis syndrome (SPS) were established in 2010 and modified in 2019. Neither set of criteria have been validated against genetic markers or proven to be the optimal criteria for defining colorectal cancer risk in patients with serrated colorectal lesions. In this study, we sought to gain insight into how frequently the change in SPS criteria in 2019 impacted the diagnosis of SPS.

Prevalence of synchronous neoplasia in patients with large pedunculated colorectal polyps.

Background: Large (≥ 20 mm) nonpedunculated colorectal lesions have high rates of synchronous neoplasia and advanced neoplasia. Synchronous neoplasia prevalence in patients with large pedunculated lesions is uncertain. We describe synchronous neoplasia in patients with large pedunculated colorectal polyps, using a cohort of patients with large nonpedunculated lesions as controls.

Outcomes of large colorectal polyp endoscopic resections during small audience live endoscopy events with endoscopist at their home endoscopy unit.

Live endoscopy courses are popular. The safety of performing live endoscopy has been questioned. In this study, we compared outcomes of large colorectal polyp resections during live endoscopy events (LEEs) (with a small audience of 2 to 5 physicians) to those removed during standard procedure days (SPDs) (without an audience).

Incidence and Predictors of Surgical Site Infection Complications in Diabetic Patients Undergoing Lower Limb Amputation.

Background: Surgical site infections (SSIs) following lower extremity amputations (LEAs) are a major cause of patient morbidity and mortality. The objectives of this study are to investigate the annual incidence of SSI and risk factors associated with SSI after LEA in diabetic patients.

Methods: LEAs performed on diabetic patients between 2005 and 2017 were retrospectively analyzed from the American College of Surgeons National Surgical Quality Improvement Program database.

Implications of stable or increasing adenoma detection rate on the need for continuous measurement.

Background And Aims: Measurement of the adenoma detection rate (ADR) is resource intensive, and the benefit of continuous measurement for colonoscopists with high ADR is unclear. We examined the ADR trends at our center to determine whether continuous measurement for consistently high ADR is warranted.

Methods: Among colonoscopies performed between January 1999 and November 2019 at a tertiary center, we analyzed data from colonoscopists performing at least 50 screening colonoscopies annually for 5 consecutive years.

Adverse events and residual lesion rate after cold endoscopic mucosal resection of serrated lesions ≥10 mm.

Background And Aims: Cold EMR is being increasingly used for large serrated lesions. We sought to measure residual lesion rates and adverse events after cold EMR of large serrated lesions.

Methods: In a single academic center, we retrospectively examined a database of serrated class lesions ≥10 mm removed with cold EMR for safety and efficacy.

Room temperature water infusion during colonoscopy insertion induces rectosigmoid colon mucus production.

Background: Water filling during colonoscopy improves several colonoscopy outcomes. We evaluated an anecdotal observation that room temperature water filling during colonoscope insertion results in mucus production in the left colon, which may impair mucosal visualization during withdrawal.

Methods: We performed 55 colonoscopies with either water or saline filling during insertion, and video recorded the examinations.

Coordinating the Provision of Health Services in Humanitarian Crises: a Systematic Review of Suggested Models.

Background: Our objective was to identify published models of coordination between entities funding or delivering health services in humanitarian crises, whether the coordination took place during or after the crises.

Methods: We included reports describing models of coordination in sufficient detail to allow reproducibility. We also included reports describing implementation of identified models, as case studies.
