Obliterated processus vaginalis diagnosed by intraoperative laparoscopy is unlikely to develop into a clinical hernia
Background:
This study was conducted to evaluate if a subsequent inguinal hernia would occur in the contralateral obliterated processus vaginalis shown by intraoperative laparoscopic examination.
Methods:
From July, 1993 to February, 1994, 120 patients with a unilateral inguinal hernia were identified as obliterated processus vaginalis by intraoperative laparoscopic examination of the contralateral internal ring when they received unilateral herniorrhaphy. A five-year follow-up of the contralateral side to determine the rate of subsequent inguinal hernia was carried out during an outpatient clinic check-up or by telephone contact.
Results:
One patient, among the first few patients having laparoscopic examinations, had a subsequent contralateral inguinal hernia. Two patients had hydroceles and each of the operative findings was a communicating hydrocele that could not possibly develop into a clinical hernia.
Conclusions:
It is unlikely for an obliterated processus vaginalis indicated by intraoperative laparoscopic examination to become a clinical inguinal hernia.
