We conducted this study to investigate the efficacy, safety, and clinical value of postoperative compression in preventing seroma formation, relieving acute pain, and improving QoL after groin hernia repair.
This multi-center, prospective, observational real-world study was conducted from March 1, 2022, to August 31, 2022. The study was completed in 53 hospitals in 25 provinces in China. A total of 497 patients who underwent groin hernia repair were enrolled. All patients used a compression device to compress the operative region after surgery. The primary outcome was seroma incidence 1 month after surgery. Secondary outcomes included postoperative acute pain and QoL.
A total of 497 patients [median (IQR) age 55 (41–67) years, 456 (91.8%) male] were enrolled, of whom 454 underwent laparoscopic groin hernia repair and 43 open hernia repair. The follow-up rate was 98.4% 1 month after surgery. Seroma incidence was 7.2% (35 of 489 patients) overall, lower than reported by previous research. No significant differences were found between the two groups (P > 0.05). VAS scores after compression were significantly lower than before compression overall and in both groups (P < 0.001). The laparoscopic group showed a high level of QoL compared with the open group, but there was no significant difference between the two groups (P > 0.05). CCS score correlated positively with VAS score.
Postoperative compression, to a certain extent, can reduce seroma incidence, relieve postoperative acute pain, and improve QoL after groin hernia repair. Further large-scale randomized controlled studies are warranted to determine long-term outcomes.
