Atypical incisional hernia following Pfannenstiel incision.
BACKGROUND
Herniation following Pfannenstiel incision is rare. Closure of the incision in four layers including the rectii abdominis, is done uncommonly. The authors report five cases of interstitial herniae between the rectus muscles and the anterior rectus sheath, incarcerating omentum and bowel. Four patients underwent repair, two as an emergency. One patient was managed conservatively.


METHODS
Subsequently all consultant and specialist registrars in obstetrics and gynaecology in the Wessex region were sent questionnaires on their methods of closure of Pfannenstiel incisions and rates of associated herniae. Fifty-three of 74 surgeons responded and only three (5.6 %) routinely closed the abdominal recti. The surveyed surgeons felt post-Pfannenstiel incisional hernia rates were low (0-1 %) though the rate was unknown to 33 % of surgeons.


CONCLUSIONS
Complex incisional interstitial herniae of this type have not previously been described. Closure of the rectii abdominis (as originally described by Pfannenstiel in 1900) could minimise the incidence of incisional herniae.
