[Postoperative cicatrical hernias of the Spigelian line].

Among 640 patients operated upon due to multiple recurrences of ventral hernias Spigelian hernia was revealed in 11 cases, and primary surgery for Spigelian hernia was performed only in one case. The diagnosis of Spigelian hernias in this category of patients presents considerable difficulties. It is the authors' opinion that operative treatment of Spigelian hernias after repeat operations on abdominal organs should be performed with application of allomaterials. As an alloprosthesis the authors recommend to use a specially manufactured material from Lavsan threads No 200 with 2-3 mm mesh. An examination of patients 10-12 years following herniotomy indicated that neither recurrent hernia nor complications related with the utilization of Lavsan alloprosthesis were noted in any case.
