Atraumatic laparoscopic intraperitoneal mesh fixation using a new laparoscopic device: an animal experimental study.

PURPOSE: Laparoscopic ventral and incisional hernia repair (LVIHR) has become a common procedure because of its feasibility and safety, but it is not free of complications. Acute and chronic post-operative pain and bleeding caused by traumatic fixation of the mesh are frequently prolonging the hospital stay. The aim of this study was to analyze the behavior of n-butyl-cyanoacrylate (GLUBRAN® 2) as only mesh fixation METHODS: Ten female pigs were involved in the study and were divided into two groups of five (A and B). Animals in each group underwent a laparoscopic procedure in which two meshes were placed intraperitoneally and fixed with the same synthetic glue only. Animals in group A were sacrificed after 3 weeks, and those in group B were sacrificed after 12 weeks. We studied the morphological, biomechanical, and histological characteristics of the intraperitoneal mesh-tissue interface RESULTS: No disruption, migration or folding was observed in any of the pigs. In group A, the mean tensile strength was 1.4 N/cm (± 0.2) while in group B, the mean tensile strength was 2.5 N/cm (± 0.8). Histological analyses, in areas where mesh was fixed using the glue, showed a chronic lymphocytic inflammatory reaction with a granulomatous component and a marked desmoplastic reaction made up of immature collagen and numerous fibroblasts acquiring myofibroblastic characteristics. In some areas corresponding to fixation, the desmoplastic reaction originated from mature lamellar bone tissue with osteocytes and osteoblasts. CONCLUSION: Laparoscopic mesh fixation with only the synthetic comonomer glue GLUBRAN® 2 is feasible, effective, and safe in intraperitoneal incisional/ventral hernia repair in this animal model.

Does correlation exist between anorectal manometry and endoanal ultrasound findings in healthy subjects according to age?

BACKGROUND: different studies have demonstrated the correlation between anorectal manometry and endoanal ultrasonography data in patients with fecal incontinence, but there is no almost interest describing the same in healthy subjects according to age. AIMS: to study the possible correlation between anorectal manometry and endoanal ultrasonography data in a homogeneous group of healthy women, also according to age. MATERIAL AND METHODS: prospective observational study of a healthy subjects cohort (n=14). Homogeneous group of healthy volunteer women divided in 2 subgroups according to age. RESULTS: there was no proved correlation between the internal anal sphincter's measurement and the resting pressure in the whole sample as well as the analysis according to age. Neither there was any proved statistically significant correlation between the external anal sphincter´s thickness and the squeeze pressure, in the whole sample and by groups. CONCLUSIONS: it does not exist statistically significant correlation between the thickness of the sphincters and its function in a healthy subjects homogeneous group, neither in 2 groups according to age.

Prevalence of faecal incontinence and analysis of its impact on quality of life and mental health.

AIM: Faecal incontinence is a significant healthcare problem, with an estimated prevalence of up to 5% of the general population. Little is known about its prevalence among patients attending primary care. METHOD: A cross-sectional multicentre study was undertaken. Adult patients attending 10 primary health centres were interviewed. Faecal incontinence was defined as involuntary leakage of flatus, liquid or solid stool at least once in the preceding 4 weeks. Health-related and disease-specific quality of life was assessed using the 36-item Short-Form Health Survey and the Fecal Incontinence Quality of Life scale, respectively. Mental health status was assessed using the 28-item General Health Questionnaire. An adjusted multivariate analysis was performed to study the association of faecal incontinence with the presence of altered mental health status. RESULTS: A total of 518 subjects (mean age 60.3 years) were studied. The prevalence of faecal incontinence was 10.8%. Altered mental health status was found in 51.8% of patients with faecal incontinence and in 30.5% of those without (P = 0.001). Faecal incontinence was a significant independent factor for altered mental health status (odds ratio, 2.088; 95% CI 1.138-3.829; P = 0.017). CONCLUSION: The prevalence of faecal incontinence in primary care is high, with a significant impact on quality of life and mental health status.
