Clinical features and long-term outcomes of lower esophageal sphincter-dependent and lower esophageal sphincter-independent jackhammer esophagus.

Background: The most recent Chicago Classification expanded the criteria for diagnosis of jackhammer esophagus (JHE) to include the distal contractile integral (DCI) of the lower esophageal sphincter (LES). The clinical impact of the manometric inclusion of LES hypercontractility remains unclear. We aimed to analyze the clinical features and long-term outcomes of measured LES-dependent (LD-JHE) and LES-independent (LI-JHE) jackhammer esophagus.

Comparison of Small Versus Large Volume Split Dose Preparation for Colonoscopy: A Study of Colonoscopy Outcomes.

Background: Split dose bowel preparations (SDP) have superior outcomes for colonoscopy as compared to evening before regimens. However, the association of the actual volume of the SDP to colonoscopy outcome measures has not been well studied.

Aims: Compare adenoma detection rate (ADR), sessile serrated polyp detection rate (SDR), mean bowel cleanse score, and predictors of inadequate exams between small volume SDP and large volume SDP.
