Parastomal hernias (PHs) frequently complicate enterostomy creation. Decision for PH repair (PHR) is driven by patient symptoms due to the frequency of complications and recurrences. The European Hernia Society (EHS) PH classification is based on the PH defect size and the presence/ absence of concomitant incisional hernia. The aim of this study was to evaluate PHR outcomes based on EHS classification. An Institutional Review Board–approved retrospective review of a prospective database between 2009 and 2017 was performed. Patient demographics, enterostomy type, EHS classification, operative technique, and clinical outcomes (postoperative complications, 30-day readmission, and PH recurrence) were obtained. Cases were analyzed by EHS classifications I and II (SmallPH) versus III and IV (LargePH). Sixty-two patients underwent PHR (35: SmallPH, 27: LargePH). Patient groups (SmallPH vs LargePH) were similar based on American Society of Anesthesiologists Class III and obesity. Hernia recurrence was seen in 26 per cent of repairs with no difference between groups. The median recurrence-free survival was 3.9 years. There was no difference in superficial SSI, deep SSI, nonwound complications, or readmission between SmallPH and LargePH. Both small and large PHs experience similar outcomes after repair. Strategies to improve outcomes should be developed and implemented universally across all EHS PH classes.

Introduction:Current guidelines recommend at least 3 months of guideline-directed medical therapy (GDMT) for patients with a new onset of non-ischemic cardiomyopathy (NICM) and left bundle branch block (LBBB) prior to cardiac resynchronization therapy (CRT). For patients who do not receive optimal GDMT, response to CRT is unknown.Methods: Patients with NICM and LBBB with QRS ≥ 120 ms were identified among all patients who underwent CRT. Patients who received GDMT for ≥ 3 months before CRT were compared to those who did not. Among 38 patients who met inclusion criteria, 24 received optimal GDMT prior to implantation (Group 1) and 14 did not (Group 2).Results: QRS narrowing occurred in Group 1 (160 AE 9 ms to 138 AE 20 ms, P = 0.001) and Group 2 (160 AE 17 ms to 139 AE 30 ms, P = 0.021). Left ventricular ejection fraction (LVEF) improvement occurred in Group 1 (21.3 AE 5.9% to 34.4 AE 13.9%, P < 0.001) and Group 2 (18.8 AE 4.7% to 31.1 AE 13%, P = 0.010). QRS interval and LVEF changes were similar between groups (P = NS). There was a trend towards greater CRT response in women than in men, although differences did not reach statistical significance. Conclusion:In patients with NICM and LBBB, CRT is associated with improvements in LV size and function independent of prior GDMT. The ability of resynchronization to improve LVEF without GDMT suggests that CRT without waiting 3 months for GDMT optimization may benefit some patients with NICM and LBBB.
