"Double N": Evolution of the Surgical Technique for Laparoscopic Herniorrhaphy After 10-Year Experience in a Single Center

Derivation of a complication burden score based on disability-adjusted life years to assess patient burden following surgery: a pilot study

BACKGROUND

Comparing adverse outcomes following alternative surgical interventions is a complex process for both patients and providers. Disability-adjusted life years (DALYs) are used globally as a quantitative indicator of burden of disease. However, DALYs have not been applied to the burden of postoperative complications. This study explores the feasibility and utility of DALYs in measuring the burden of postoperative complications, using 2 pediatric surgical procedures as a test model.

METHODS

A literature review was undertaken of postoperative complications following pediatric inguinal hernia repair and intestinal atresia repair. Relevant studies were included, and incidence rates and durations of all key complications were identified. Using existing disability weights of equivalent health states to the complications, we estimated the burden in DALYs of each complication. These estimates were combined into a unitary procedure-specific complication burden score.

RESULTS

The key complications contributing to the postoperative burden following inguinal hernia repair were recurrence (0.016 DALYs), hydrocele (0.010), metachronous hernia (0.014) and port-site hernia (0.012). In the case of intestinal atresia repair, death (6.278), reoperation (12.100), stenosis (5.025) and anastomotic stricture (5.327) accounted for most of the postoperative DALYs. The complication burden score was 0.06 DALYs for inguinal hernia and 36.86 for intestinal atresia repair.

CONCLUSION

As a proof of concept, this study supports the feasibility of using DALYs to derive a complication burden score following surgical intervention, and to our knowledge it represents the first application of burden of disease metrics to postoperative adverse outcomes. Future studies should focus on deriving de novo disability weights for common postoperative complications and adverse outcomes.

Laparoscopic Treatment of Inguinal Ovarian Hernia in Female Infants and Children: Standardizing the Technique

BACKGROUND

Sliding indirect inguinal hernias containing ovary are not uncommon in girls. We reported our experience with laparoscopic treatment of inguinal ovarian hernias in female infants and children with the aim to standardize the surgical technique.

METHODS

The medical records of all girls who underwent laparoscopic inguinal hernia repair in our unit over the past 5 years were retrospectively reviewed. Only patients with an ovary found intraoperatively in the hernia sac were included in the study. All patients younger than 1 year received preoperatively a bowel preparation with simethicone and enemas.

RESULTS

A total of 289 girls (median age 3.2 ± 0.5 years) underwent laparoscopic inguinal hernia repair during the study period. Thirty-seven patients (12.8%) had an ovarian hernia and were included in the study. Of these 37 girls, 9 (28.1%) were younger than 1 month, 20 (62.5%) ranged in age from 2 months to 1 year, and 3 (9.4%) were from 1 to 7 years. The average operative time was 23.7 minutes (range 18-43 minutes). No necrotic ovary was found intraoperatively, and all the procedures were accomplished laparoscopically. Neither intraoperative nor postoperative complications were reported. A patency of the contralateral canal of Nuck was found in 16 of the 37 patients (43.2%) and repaired during the same procedure. The average length of hospitalization was 21.8 hours (range 18-36 hours). No hernia recurrence or ovarian atrophy was recorded at a mean follow-up of 36 months (range 1-60 months).

CONCLUSIONS

On the basis of our experience, laparoscopy should be considered the gold standard for the treatment of inguinal ovarian hernias in girls. Key points for standardization of the technique are as follows: bowel preparation in children younger than 1 year, use of 5-mm umbilical balloon trocar, correct positioning of 3-mm working screw trocars, section of the abnormal attachment of ovarian suspensory ligament, section of the periorificial peritoneum, and use of nonresorbable sutures.
