Abstract
BACKGROUND: A true incidence of occult inguinal and Spigelian hernias in adult population is unknown. The frequency of incipient hernias was studied during laparoscopy of other abdominal diseases. METHODS: The 201 laparoscopic procedures included 104 cholecystectomies, 55 fundoplications, 36 diagnostic, and 6 miscellaneous operations. There were 133 females and 68 males with a mean age of 53 +/- 14 years. The orifices of all inguinal and Spigelian hernias were carefully recorded at the beginning of laparoscopy by using 30 degrees optic. RESULTS: The overall frequency of unexpected hernias was 43 of 201 (21%) including 36 (18%) inguinal hernias, 5 (2%) Spigelian hernias and 2 (1%) ventral hernias. The number of hernias was higher in males than in females (P = .003). The most common finding was indirect inguinal hernia in 27 (13%) subjects. Usually hernia orifices were insignificant and only 5 of 201 laparoscopic hernioplasties were undertaken without any complications. CONCLUSIONS: Occult hernia orifices are commonly found in laparoscopic operation. Usually the defects are asymptomatic and hernioplasty is not needed. Herniation of Spigelian fascia is rare (<2%) in adults during laparoscopy.
