Rates of complications in Achilles tendon rupture repair using absorbable and nonabsorbable suture material; A systematic review

BACKGROUND

The impact of suture type on tensile strength, re-rupture rates and infection risk in Achilles tendon rupture repair is not been well established. The aim of this review is to evaluate existing literature on the associated risk of postoperative infection with absorbable and non-absorbable suture materials in Achilles tendon rupture repair.

METHODS

A systematic review of search databases PubMed; Google Scholar; and OVID Medline was made to identify studies related to complications associated with Achilles tendon rupture repair. PRISMA guidelines were utilised for this review. Meta-analysis was used to compare rupture rates and infections following rupture repair.

RESULTS

12 studies with a total of 460 patients, 230 in both nonabsorbable and absorbable suture groups were included for analysis. Risk of wound complications was significantly higher in patients with non-absorbable sutures (p < 0.001).

CONCLUSION

Nonabsorbable braided sutures is associated with the highest risk of postoperative wound complications following Achilles tendon rupture repair.

Absorbable versus non-absorbable sutures for vaginal mesh attachment during sacrocolpopexy: a randomized controlled trial

INTRODUCTION AND HYPOTHESIS

The purpose of the study was to analyze anatomical and functional outcomes after sacrocolpopexy (SCP) for vaginal vault prolapse pelvic organ prolapse quantification (POPQ) II-III by random use of absorbable (Vicryl) and non-absorbable sutures (Ethibond) for vaginal mesh fixation.

METHODS

This study was designed as a two-center randomized controlled study (RCT). The primary objective was to evaluate the anatomical outcome. Success was defined when the vaginal apex (point C; POPQ) did not descend more than 50% of the total vaginal length (tvl) during Valsalva. Patients completed a pelvic examination incorporating the POPQ and questionnaires (the German pelvic floor questionnaire and the PISQ-12 questionnaire) at baseline and 6 months postsurgery. Perioperative adverse events (AE) were recorded. Sample size calculations, based on a 10% non-inferiority limit required 100 participants per group, with power = 90%.

RESULTS

In 190 out of 195 women (ETH group n = 96; VIC group n = 94) anatomical success was achieved. The relative risk of anatomical success failure in the VIC group versus the ETH group was 0.69, with a 95% confidence interval 0.12-4.02. The change in the symptom scores did not differ significantly between the ETH and the VIC group. In the ETH group, three suture penetrations into the vagina were observed, and none in the VIC group 6 months postoperatively.

CONCLUSIONS

Anatomical success after SCP for vaginal vault prolapse POPQ II-III is not affected by suture type for vaginal monofilament mesh attachment. Moreover, we did not see any differences in functional outcomes between the two groups. Three suture penetrations into the vagina were observed in the ETH group, and none in the VIC group 6 months postoperatively.
