METHODS: Incidence of thigh pain was lower in 2008 compared to 2006 and 2007 (p < 0.0001). The percentage of patients requiring blood transfusions (p = 0.09), duration of IDC ≥ 7 days (p = 0.27), wound dehiscence and re-operation rate were lower in 2008 in contrast to 2006 and 2007 (p = 0.43). Only 209 patients (82.3%) were available for review at 1 year. There were two (1.0%) cases of recurrent vault prolapse.
RESULTS: The subjective and objective cure rates at 1 year after this mesh implant surgery in 2006, 2007 and 2008 were 92.1% and 92.1%; 97.0% and 92.4% and 100% and 97%, respectively. The mesh erosion rate was remarkably lower in 2008 as compared to 2007 and 2006 (p < 0.001).
CONCLUSIONS: This synthetic mesh-augmented implant surgery is effective and safe, and surgical outcome appears related to the learning curve of the surgeon.
CASE PRESENTATION: A 61-year old lady with previous peptic ulcer disease underwent a laparoscopic intraperitoneal placement of mesh for incisional hernia utilising a fish oil coated polypropylene mesh. The patient presented 3 months after the procedure complaining of dyspepsia and pain at the operative site. There was no discharge. The patient was managed conservatively. She presented 10 months post-operatively with progressively worsening symptoms and a hard palpable mass in the epigastrium. Abdominal laparoscopy revealed dense adhesive disease around the mesh with exudates. Adhesiolysis, mesh explantation and a partial gastrectomy was performed. Histopathological examination revealed a foreign body granuloma formation to the mesh.
CONCLUSION: In-vivo studies looking at intraperitoneal mesh placement with fish oil coatings including data on surgical outcomes such as fistula and adhesive characteristics are scarce in the literature. Further monitoring and studies are required to investigate the safety and efficacy profile of this mesh type in in-vivo models.
STUDY DESIGN: The study is a prospective observational study which included 122 patients who had symptomatic POP stage III and IV. AvaultaPlus™ (collagen coated, CC group) was compared to Perigee™ (non collagen coated, NC group). Introital ultrasound morphology, measure of neovascularization by color Doppler and clinical outcomes were assessed. Student t test was used for comparison of pre- and post-operation continuous data (p value of <0.05).
RESULTS: A total of 110 (CC group=50, NC group=60) women completed the study. A woman in the CC group developed ureteral injury. Both groups had comparable morphologic and clinical outcomes however, the onset of changes in mesh thickness and neovascularization occurred earlier in the NC group (1 month) compared to the CC group (6 months to 1 year).
CONCLUSION: CC group was comparable to the NC group in terms of erosion rate, ultrasound and clinical assessment. Collagen coating may induce delayed inflammatory response however may also delay tissue integration. The onset of changes in mesh thickness and neovascularization may give us an insight toward utilization of collagen coated mesh for host-tissue integration.
METHODS: Thirty-eight female Sprague-Dawley rats were divided into three groups: mesh, sham (no mesh), and control. Urodynamic study and NGF analysis of the urogenital tissues were done and results were compared among all groups. The urodynamic studies of the mesh and sham groups were further divided into the 4th and 10th days. A P-value mesh and sham groups when compared to the control. The mesh group showed a larger area of inflammation as compared to the sham. The NGF levels increased significantly in the mesh and sham groups on the 4th and 10th days when compared to the control (P < 0.001, P < 0.001, respectively). Both the mesh and sham groups had shorter voiding interval and lower voiding volume on days 4 and 10 when compared to the control group (P mesh group than the sham group.
CONCLUSION: A higher level of NGF in the early days post-transvaginal mesh implantation is associated with a shorter voiding interval and a smaller bladder capacity, which represents abnormal lower urinary tract symptoms following transvaginal mesh implantation.
