Laparoscopic versus open groin hernia repair in older adults: a systematic review and meta-analysis.

BACKGROUND

Groin hernia repair is a common surgical procedure and includes both open and laparoscopic techniques. Studies comparing outcomes of laparoscopic versus open groin hernia repair specifically in the geriatric population are lacking. This study compares the outcomes of laparoscopic versus open groin hernia repair techniques in older adults.

METHODS

A literature search was conducted in each of the five selected databases up till June 2021: PubMed (MEDLINE), EMBASE, CINAHL, Cochrane and PsychInfo (OVID). Outcomes measured included but were not limited to total length of hospital stay, mean total operative time, intraoperative complications, post-operative complications such as wound infection, seroma formation, chronic pain, mesh infection and recurrence of inguinal hernia.

RESULTS

A total of five articles were included in the final analysis. The length of postoperative hospitalization stay was shorter in patients who underwent laparoscopic hernia repair (95% CI: -1.50 to -0.72; P < 0.01, I  = 79%). The laparoscopic repair group had a significantly smaller number of patients who sustained postoperative wound infections (95% CI: 0.02 to 0.47; P = 0.003, I  = 0%), and lower incidence of chronic pain (95% CI: 0.14 to 0.37, P < 0.01, I  = 46%). Analysis of the remaining outcomes did not reveal any statistically significant differences between open and laparoscopic hernia repair.

CONCLUSIONS

The results of this analysis showed a shorter length of stay, lower wound infection rates and lower chronic pain with laparoscopic groin hernia repair as compared to open repair in older adults. Future prospective studies examining the impact of age on the relationship between surgical approach (open versus laparoscopic) and surgical outcomes are needed.
