Mechanical strength of biliary defect closure after topical sealing: Comparison of four sealants in a porcine model

Long-term persistence of carrier-bound fibrin sealant (TachoSil®) following abdominal surgery: a decade-long follow-up study

This study analyzed the long-term effects of carrier-bound fibrin sealant (CBFS) following abdominal surgery by tracking patients for years post-application. From 2006 to 2022, patients who underwent this procedure were contacted via telephone. Those who died due to underlying diseases, natural causes, or refused the check-up were excluded from the study. After 11 years of follow-up, CBFS was observed in different forms on computed tomography scans in four patients. Our findings indicate that CBFS can persist for years after the procedure. While we cannot confirm any secondary effects, it appears that CBFS sponges are not resorbed within 12 weeks and can remain for many years post-implantation.

Collagen patch cover facilitates recovery of bowel function after laparoscopic colectomy

BACKGROUND

Numerous factors can influence bowel movement recovery and anastomotic healing in colorectal surgery, and poor healing can lead to severe complications and increased medical expenses. Collagen patch cover (CPC) is a promising biomaterial that has been demonstrated to be safe in animal models and has been successfully applied in various surgical procedures in humans. This study.

METHODS

A retrospective review of medical records from July 2020 to June 2022 was conducted to identify consecutive patients who underwent laparoscopic colectomy. Patients who received CPC at the anastomotic site were assigned to the collagen group, whereas those who did not receive CPC were assigned to the control group.

RESULTS

Data from 241 patients (collagen group, 109; control group, 132) were analyzed. Relative to the control group, the collagen group exhibited a faster recovery of bowel function, including an earlier onset of first flatus (2.93 days vs. 3.43 days, p < 0.01), first defecation (3.73 days vs. 4.18 days, p = 0.01), and oral intake (4.30 days vs. 4.68 days, p = 0.04). CPC use was also associated with lower use of postoperative intravenous analgesics. The complication rates in the two groups did not differ significantly.

CONCLUSIONS

CPCs can be safely and easily applied to the anastomotic site during laparoscopic colectomy, and can accelerate bowel movement recovery. Further studies on the effectiveness of CPCs in colorectal surgery involving larger sample sizes are required.
