[show abstract][hide abstract] ABSTRACT: To report a multiinstitutional experience of men presenting with infertility secondary to inguinal hernia repair using polypropylene mesh.
An estimated 80% of inguinal hernia operations involve placement of a knitted polypropylene mesh to form a "tension-free" herniorrhaphy. The prosthetic mesh induces a chronic foreign-body fibroblastic response creating scar tissue that imparts strength to the floor and leads to fewer recurrences. However, little is known about the long-term effects of the polypropylene mesh on the vas deferens, especially with regard to fertility.
Eight institutions in the United States reported a total of 14 cases of azoospermia secondary to inguinal vasal obstruction related to previous polypropylene mesh herniorrhaphy. Patient characteristics and operative findings were forwarded to 1 center for tabulation of data.
Mean patient age was 35.5 years with an average duration of infertility of 1.8 years. Mean number of years between urologic evaluation and herniorrhaphy was 6.3 years. Types of inguinal hernia repair previously performed were: open (10), laparoscopic (2), or both (2). Nine patients had bilateral obstruction and 5 patients had unilateral obstruction with contralateral testicular atrophy or epididymal obstruction. Surgical exploration revealed a dense fibroblastic response encompassing the polypropylene mesh with either trapped or obliterated vas in all patients. Surgical reconstruction was performed in 8 of 14 men (57%).
Reconstruction to restore fertility can be difficult secondary to fibrotic reaction. Before undergoing polypropylene mesh herniorrhaphy, men, especially of young reproductive age or with a solitary testicle, need to be carefully advised of potential obstruction and compromise to future fertility.

[show abstract][hide abstract] ABSTRACT: Study was conducted to evaluate the feasibility and benefits of inguinal hernia repair with prolene hernia system (PHS) mesh under local anaesthesia as a day surgery procedure in a multinational society of United Arab Emirates. One hundred and seventy-eight inguinal hernias in 172 consecutive adults of whom 154 (89.5%) fitted the criteria of inclusion in the day-case surgery settings were operated upon including one early recurrence. Conversion from local to general anaesthesia was required in five (2.8%) patients. The mean operation time was 65 min, including the anaesthesia injection. The mean hospital stay was 2.1 days for all patients and 1.01 days for those who fitted in the ambulatory surgery program. Inguinal hernia repair using the PHS technique under local anaesthesia could be mastered by many of the surgeons in our hospital with minimal morbidity and short hospital stay with a potential to lessen recurrence.
[show abstract][hide abstract] ABSTRACT: Massive ventral hernias are difficult to repair, especially with multiple recurrences. Numerous methods of repair have been described with an overall recurrence rate up to 33% after first repair and 44% after second repair, mostly occurring within 3 years of the repair.
This is a prospective study on 41 patients who underwent surgery between January 2000 and August 2004 for recurrent large ventral hernias. Patients were randomized into two groups: group A included 22 patients, who were subjected to suture repair with an onlay polypropylene mesh, and group B, which included 19 patients, who were subjected to a tailored double mesh (Vicryl + polypropylene) intraperitoneal repair.
Superficial wound infection occurred in two patients (4.8%), one in each group. By a median follow up of 30 months, seroma formation or hernia recurrence was not found in group B in comparison to seven and six cases, respectively, in group A (p < or = 0.000). There was no intraabdominal complication in the cases subjected to double mesh intraperitoneal repair due to the protective effect of the inner Vicryl layer, which is characterized by its low reactivity.
A double mesh intraperitoneal repair (ADMIR) is successful for the repair of recurrent large ventral hernias as it is applicable to all sites of ventral hernias. The mesh is mostly hidden within the abdomen with relatively affordable pain allowing for early mobilization, the complication rate is low and so far no recurrence was reported. A long-term follow up with a larger number of cases is advisable in order to determine the long-term success of this kind of repair.
