Review Case Reports
Handlebar hernia: a case report and literature review on traumatic abdominal wall hernia in children.
A rare case of abdominal trauma, a handlebar hernia, is described, as well as a review of the pertinent literature. A 7-year-old boy presented to our emergency room after sustaining blunt force to the abdomen; he fell on the handlebar of his bicycle. ⋯ Handlebar hernia is a diagnosis that is easily missed, which can lead to strangulation and incarceration of the bowel. With this case report, we hope to augment the knowledge on traumatic abdominal wall hernia, hopefully leading to early diagnosis and treatment.

Biologic meshes are increasingly used in parastomal hernia repair. This study evaluates the efficacy and safety of diisocyanate cross-linked acellular porcine dermal collagen mesh for parastomal hernia repair, with particular reference to the relationship of the stoma site to the rectus sheath. ⋯ For parastomal hernias within the rectus sheath, diisocyanate cross-linked porcine dermal collagen mesh onlay repair gives good results and is safe to use. Repair of a parastomal hernia where the stoma is lateral to the rectus sheath has a significantly higher risk of recurrence and is not recommended.

Clinical Trial
Occult hernias detected by laparoscopic totally extra-peritoneal inguinal hernia repair: a prospective study.
One distinct advantage of laparoscopic inguinal hernia repair is the opportunity for clear visualization of the direct, indirect, femoral, obturator and other groin spaces. The aim of this study was to examine/assess the potential of the laparoscopic totally extraperitoneal (TEP) inguinal hernia repair method in detecting unexpected additional hernias. ⋯ The laparoscopic inguinal hernia repair approach allows viewing of the entire myopectineal orifice, facilitating repair of any unexpected hernias and thereby reducing the chance of recurrence.

Incisional hernia is a long-term complication of laparotomy. Its exact frequency varies according to different authors, but is always around 10-15%. There are patients who present with systemic associated diseases [chronic obstructive pulmonary disease (COPD), obesity, severe cardiopathies, immunodeficiencies, etc.] that favour or increase the risk of appearance of an incisional hernia. The aim of the present study was to assess whether the prophylactic placement of a polypropylene mesh in patients at risk can reduce or avoid the appearance of an incisional hernia. ⋯ Prophylactic use of a low-molecular-weight polypropylene mesh in abdominal surgery may be useful for the prevention of incisional hernia.

To evaluate the biocompatibility of heavyweight polypropylene (HWPP), lightweight polypropylene (LWPP), and monofilament knit polytetrafluoroethylene (mkPTFE) mesh by comparing biomechanics and histologic response at 1, 3, and 5 months in a porcine model of incisional hernia repair. ⋯ The maximum tensile strength of mesh in the abdominal wall decreased over time for HWPP, LWPP, and mkPTFE mesh materials alike. This trend may actually reflect inability to adequately grip specimens at later time points rather than any mesh-specific trend. Histologically, inflammation decreased with time (P = 0.000), and tissue ingrowth increased (P = 0.019) for all meshes. No specific trends were observed between the polypropylene meshes and the monofilament knit PTFE, suggesting that this novel construction may be a suitable alternative to existing polypropylene meshes.
