Modified open anterior mesh repair Effective for Groin Hernias in Women in Low-Resource Settings: JAMA
Researchers have found in a new randomized clinical trial that modified open anterior mesh repair repair is a suitable option for groin hernia repair in women, especially in low-resource settings. Femoral hernias were highly prevalent, and exposing the femoral canal was crucial for their accurate detection. The study was published in JAMA Network by Alphonsus M. and colleagues.
The research was a two-arm, double-blind, randomized clinical trial between October 2019 and February 2023 in two public hospitals in Northern Uganda. The trial recruited 200 adult females aged 18 years or more, who all had a primary groin hernia and were of American Society of Anesthesiologists (ASA) class I or II. Informed consent was given by all the subjects. The women were randomized to receive either the routine OAM repair or the MOAM repair, the primary difference in the MOAM technique being opening of the transversalis fascia and closure of the femoral canal with a mesh flap.
There were 200 women who participated in the trial. The mean age was 52.7 years with a standard deviation of 14.0 years. Of the 200 women, 99 (49.5%) were randomly assigned to the OAM repair and 101 (50.5%) to the MOAM repair. It was interesting to observe that almost 45% of the participants (89 out of 200) had a femoral hernia. Surprisingly, 35 women (35.4%) assigned initially to the OAM group received the MOAM procedure instead because of intraoperative findings of femoral hernias necessitating femoral canal exposure.
