Dynamic self-regulating prosthesis in inguinal hernia repair

Inguinal hernia repair is one of the most common surgical procedure performed in Western countries and it consumes a lot of healthcare resources. Several types of different mesh are now disposable and tension-free techniques represent the “golden standard”. In our study, fifty male patients were operated on for inguinal hernia and a PAD (i.e., dynamic self-regulating prosthesis) used for the repair of the inguinal defect: this technique demonstrated to be safe, effective and easy to perform.

Small bowel obstruction caused by mesh migration. Case report

Introduction. Endoscopic hernia repair methods have become increasingly popular over the past 15 years. Nonetheless, there is no consensus regarding an optimal fixation method. Transabdominal sutures and titanium tacks or staples are the most traditional ones. Case report. We present a case of mechanic small bowel obstruction due to mesh migration occurring one year and a half after incisional hernia repair with polytetrafluoroethylene mesh fixed by spiral tacks. Discussion. Titanium spiral tacks are dangerous because of their sharp components, which can damage organs such as the small intestine, by causing microperforations. The type of prosthesis used has also contributed to the intraluminal migration, since polytetrafluoroethylene mesh is very flexible and poorly integrates in the abdominal wall. Conclusion. A prosthesis of a different material combined with a different fixation system such as absorbable tacks, biological glue, or mechanical tacks without sharp components, would have obviated mesh migration. .
