RESUMEN

BACKGROUND: The incidence of direct inguinal hernia in the pediatric population is relatively low and is usually discovered intraoperatively, rendering it unfamiliar to most pediatric surgeons. The traditional approach involves directly addressing the peritoneal defect, which includes dissecting the sac and repairing the peritoneum, reinforced with the umbilical ligament. In this paper, we present our experience with a novel approach to anatomical repair utilizing a non-mesh transabdominal preperitoneal (TAPP) approach. METHODS: This a retrospective case series of direct inguinal hernia that were operated laparoscopically using the novel approach of repair from January 2018 to January 2024. Data were analyzed for demographics, presentation, type of defect, operative time, complications, and recurrence. The new approach utilizes the pre-peritoneal approach to delineate the exact facial defect then, primary anatomical repair is established using 2/0 non-absorbable braided sutures. Finally, closure of the peritoneum was performed using running 4/0 absorbable sutures. This is a retrospective case series of direct inguinal hernias that were operated on laparoscopically using the novel repair approach from January 2018 to January 2024. Data were analyzed for demographics, presentation, type of defect, operative time, complications, and recurrence. The new approach employs the pre-peritoneal approach to accurately delineate the fascial defect, followed by primary anatomical repair using 2/0 non-absorbable braided sutures. Finally, the peritoneum is closed using running 4/0 absorbable sutures. RESULTS: Data from nine cases were included. Six cases were on right side, and three cases were on left side. Patients were predominantly boys (8 boys and 1 girl). The mean age at operation was 25.1 months (range:11 month to 5 years). Four patients had previous indirect inguinal hernia repair on the same side. The mean operative time was 34 ± 9 min. No intraoperative complications occurred. The median follow up period was 24 months with no recurrence was detected in any of the cases. CONCLUSION: The non-mesh TAPP approach offers excellent exposure of the fascial structures, facilitating accurate identification and repair of the defect. Despite being technically demanding, it allows for the establishment of a robust anatomical repair. No recurrences occurred in the study group; however, a longer follow up and a larger sample are needed to provide more reliable evaluation. LEVEL OF EVIDENCE: III.
