Parestomal hernia repair. Prospective observational study based on the Spanish Registry of Incisional Hernia (EVEREG)

Abstract Introduction The results of parastomal hernia (PH) repair based on data from registries are scarce. The objective of this work is to analyze the data collected on PH in the National Registry of Incisional Hernia (EVEREG) and thus evaluate current practices and results in PH repair. Methods Data from the PH cohort recorded in the period from July 2012 to June 2018 are analyzed. Complications, recurrences and associated factors of the entire PH cohort are analyzed, regardless of the type of stoma they are associated with. Subsequently, the same PH group analysis was performed in relation to a colostomy (larger group). Results 353 PH were studied. Of these, 259 (73%) were PH in the context of a terminal colostomy, 74 (21%) in the context of a terminal ileostomy, and 20 (6%) in the context of a ureteroileostomy (Bricker). The global mean age was 68.7 ± 11.1 years and 135 (38%) patients were female. The open approach and elective surgery were predominant (78% and 92% respectively); 99% were repaired with a non-absorbable synthetic mesh. Global postoperative complications were high (30.6%). As well as, the global recurrence (27.5%) after a mean follow-up of 9.4 months. Conclusions PH repair is infrequent. PH surgery seems to be associated with a high percentage of postoperative complications and recurrence.
