Background: Patient navigation (P.N.) is designed to eliminate barriers to care. The objective of this study was to evaluate the impact of a novel P.N. program on timeliness of care in patients with esophageal cancer. Methods: This retrospective study compared the timeliness of care for esophageal cancer patients before (January 2014-March 2018) and after the implementation of a novel P.N. program (April 2018-March 2020), called EDAP, at a tertiary care center. The primary outcome was time from biopsy to first treatment; secondary outcomes included time from biopsy to complete staging, biopsy to complete preoperative workup, and referral to the first point of contact. The outcomes were evaluated in the entire cohort and then in a subgroup of patients undergoing curative multimodality therapy. Results: There were 96 patients in the pre-EDAP group and 98 patients in the post-EDAP group. There was no significant difference between pre-and post-EDAP in the time from biopsy to first treatment and time from biopsy to staging in the overall cohort. In the subgroup of patients undergoing curative multimodality therapy, there was a significant decrease in time from biopsy to first treatment postnavigation (60-51 days, p = 0.02), in addition to a significant decrease in time from biopsy to preoperative workup and time from biopsy to staging. Conclusions: This is the first study demonstrating that a novel P.N. program for patients with esophageal cancer improved timeliness of care. The group of patients who benefited most were those undergoing curative multimodality therapy, likely given the extensive coordination of services required by this group. [ABSTRACT FROM AUTHOR]

Background: Peroral endoscopic myotomy (POEM) for achalasia is technically challenging to carry out in patients with type III, multiple prior treatments, prior myotomy, and sigmoid type. Herein, we present a series of consecutive patients with complex achalasia and introduce the POEM difficulty score (PDS). Aim: To demonstrate the application and discuss the utility of PDS and present the feasibility, safety, and efficacy of POEM in complex achalasia patients. Methods: Forty consecutive POEM were carried out with 28 meeting the criteria for complex achalasia. Primary outcome was clinical success (Eckardt score ≤3) at a minimum of 3 months follow‐up. Secondary outcomes included adverse events, procedural velocity and PDS. Results: Twenty‐eight complex and 12 non‐complex POEM procedures were carried out with 100% and 92% clinical success, respectively, without any major adverse events with a median follow up of 15 months (complex) and 8 months (non‐complex). Mean velocities for non‐complex, type III, prior myotomy, ≥4 procedures and sigmoid type were as follows: 4.4 ± 1.6, 4.8 ± 1.5, 5.9 ± 2.2, 6.9 ± 2.2 and 8.2 ± 3.2 min/cm, respectively. Median PDS for non‐complex, type III, prior myotomy, ≥4 treatments and sigmoid type were 1 (0–3), 2 (0–4), 2.5 (1–6), 3 (2–6) and 3.5 (1–6), respectively. PDS was shown to correlate well with procedural velocity with a correlation coefficient of 0.772 (Spearman's P < 0.001). Conclusions: PDS identifies the factors that contribute to challenging POEM procedures and correlates well with procedural velocity. The order of increasing difficulty of POEM in complex achalasia appears to be type III, prior myotomy, ≥4 treatments and sigmoid type. [ABSTRACT FROM AUTHOR]
