Design,biomechanical study,and clinical application of a new pterygo-shaped titanium mesh cage

Objective  

In recent years, Cage/SyCages or titanium mesh cages with interbody fusion have become a common surgical treatment for patients with cervical spondylosis and traumatic lesions. However, numerous complications have been reported, including hardware failure or breakage, which necessitate reoperation, and complications at the bone graft site. To improve upon the existing traditional titanium mesh cage, we designed a new pterygo-shaped titanium mesh cage (PTMC).     

One-year results of a prospective,randomised clinical trial comparing four meshes in laparoscopic inguinal hernia repair (TAPP)

Background  

A low rate of chronic pain and maximum postoperative comfort are the main goals today in inguinal hernia repair. This four-arm randomised trial compares these parameters after laparoscopic hernia repair (TAPP) with a standard heavyweight mesh (HW), a pure middleweight polypropylene mesh (MW), a lightweight composite polypropylene mesh (LW), or a titanised lightweight mesh (TLW). The primary endpoint of the study was the incidence of chronic pain of any severity at the site of hernia repair at 1 year.     

The safety of biologic mesh for laparoscopic repair of large,complicated hiatal hernia

Background  

Biologic mesh is widely used for repair of large, complicated hiatal hernias. Recently, there have been reports of complications after its implantation. We studied the course of a large group of patients who had undergone hiatal hernia repair with use of biologic mesh to determine the rate of immediate and late complications related to its use.     

Different methods of mesh fixation in open retromuscular incisional hernia repair: a comparative study in pigs

Purpose  

Reinforcement of the abdominal wall with alloplastic mesh material in incisional hernia repair is well established. To avoid dislocation and migration of the prostheses, mesh fixation is recommended. However, there seems to be a correlation between postoperative pain and mesh fixation. Furthermore, it remains unclear whether mesh fixation is necessary at all.     

Shrinkage of intraperitoneal onlay mesh in sheep: coated polyester mesh versus covered polypropylene mesh

Background  

Currently, the laparoscopic placement of intraperitoneal mesh constitutes an acceptable option in the management of ventral hernia. To date, relatively little has been published on the consequences of intra-abdominal placement of a mesh with respect to the decrease of mesh size (shrinkage).     

Serum analyses for protein,albumin and IL-1-RA serve as reliable predictors for seroma formation after incisional hernia repair

Purpose  

The aim of this study was to identify potential parameters as predictors for seroma formation after incisional hernia mesh repair.     

Testicular functions,chronic groin pain,and quality of life after laparoscopic and open mesh repair of inguinal hernia: a prospective randomized controlled trial

Background  

Laparoscopic inguinal hernia repair is still not the gold standard for patients with inguinal hernia. The aim of this study was to compare testicular dysfunction, incidence and factors influencing chronic groin pain, and quality of life after laparoscopic and open mesh repair.     

Fever after redo Nissen fundoplication with hiatal hernia repair

Background

Fevers often arise after redo fundoplication with hiatal hernia repair. We reviewed our experience to evaluate the yield of a fever work-up in this population.

Methods

We performed a retrospective review of children undergoing redo Nissen fundoplication with hiatal hernia repair between December 2001 and September 2012. Temperatures and fever evaluations of those children receiving a mesh repair were compared with those without mesh. A fever defined as temperature ≥38.4°C.

Results

Fifty one children received 46 laparoscopic, 4 open, and 1 laparoscopic converted to open procedures. Biosynthetic mesh was used in 25 children whereas 26 underwent repair without mesh. A fever occurred in 56% of those repaired with mesh compared with 23.1% without mesh (P = 0.02). A fever evaluation was conducted in 32% of those with mesh compared with 11.5% without mesh (P = 0.52). A urinary tract infection was identified in one child after mesh use and an infection was identified in two children without mesh, one pneumonia and one wound infection (P = 1). In those repaired with mesh, there was no significant difference in maximum temperature.

Conclusions

Fever is common after redo Nissen fundoplication with hiatal hernia repair and occurs more frequently, and with higher temperatures in those with mesh. Fever work-up in these patients is unlikely to yield an infectious source and is attributed to the extensive dissection during the redo procedure.     

Can infected composite mesh be salvaged?

Background  

Composite mesh, once infected, creates a difficult dilemma. Many times, the mesh is deemed unsalvageable and leads to removal and potentially more morbidity. This article describes successful salvage of infected composite mesh.     

Mesh Graft Infection Following Abdominal Hernia Repair: Risk Factor Evaluation and Strategies of Mesh Graft Preservation. A Retrospective Analysis of 476 Operations

Background  

Mesh graft infection after prosthetic hernia repair is a challenging complication usually treated by mesh removal. The aim of this study was to identify risk factors associated with mesh infection and to assess the efficacy of conservative wound therapy in preserving an infected mesh.     

Shrinkage evaluation of heavyweight and lightweight polypropylene meshes in inguinal hernia repair: a randomized controlled trial

Background  

One of the current complications in inguinal repair is shrinkage following the use of mesh. The selected mesh material, heavyweight (HWM) mesh or lightweight (LWM) mesh, is associated with the frequency of shrinkage. The aim of this study was to investigate shrinkage of these two types of mesh in a controlled trial of male inguinal hernia repair.     

Trocar-guided total tension-free vaginal mesh repair of post-hysterectomy vaginal vault prolapse

Safety and Sterilization of Mosquito Net Mesh for Humanitarian Inguinal Hernioplasty

Background  

Inguinal hernia repair is one of the most commonly performed operations in Africa. Prosthetic repair with commercially available mesh is generally considered too expensive in low-income countries. Elective groin hernia surgery with mosquito net mesh has recently been described. However, can mesh sterility in resource-poor countries be guaranteed to ensure both effectiveness and safety?     

A self-adhering mesh for inguinal hernia repair: preliminary results of a prospective,multicenter study

Background  

Prosthetic reinforcement is the gold standard treatment for inguinal hernia and reduces the risk of recurrence. Yet up to one-third of patients complain of post-surgical pain due to irritation and inflammation caused by the mesh and the fixation materials. Of these patients, 3–4% will experience severe and disabling chronic pain. We performed a prospective multicenter clinical study of a self-adhering prosthesis, consisting of a lightweight polypropylene mesh (40 g/m2) coated on each side with synthetic glue, to evaluate early postoperative complications and patient outcomes.
