Purpose: Pledget is a PTFE felt that is usually used for suture reinforcement in cardiovascular surgery. In order to minimize the difficulty in intracorporeal continuous gastrointestinal suturing by reducing the number of tied knots, we have used pledget as substitute for a knot (pledget suturing). Materials and Methods: Thirty-two consecutive patients who underwent totally laparoscopic uncut Roux-en-Y gastrojejunostomy after distal gastrectomy in our institution were enrolled in this study, and the patients were divided into three groups according to the method of intracorporeal anastomosis. Basically, intracorporeal anastomosis was performed by several firings of linear staplers; however, the entry holes for the stapler at the jejunojejunostomy and the gastrojejunostomy were closed by pledget suturing in group A (8 patients), the entry hole for the stapler at jejunojejunostomy was closed by conventional suturing in group B (8 patients), and all of the entry holes for the stapler were closed by stapling in group C (16 patients). The surgical outcomes of each group were compared to each other. Results: The anastomotic time in group A was not longer than in group B, although there were more sutures used in group A, but it was longer than in group C. The number of stapler cartridges used in group A was the smallest among the three groups. In group B, there were two cases of a break of suture material during anastomosis, there were no such cases in group A. There was no complication related to anastomosis in all of the groups. Conclusion: Pledget was found to be useful for minimizing the difficulty in intracoproreal continuous gastrointestinal suturing and reducing the number of stapler cartilages used in intracorporeal anastomosis.

Purpose: In arthroscopic rotator cuff repairs there are generally weak link in tendon suture interface, arthroscopic rotator cuff repairs can have higher retear rates than open repairs. The purpose of this study was to compare the strength of UU (Ulsan University) suture than open modified MA (Mason-Allen) suture when suture anchored into bone. Materials and Methods: The human supraspinatus tendons were harvested from the shoulder of the cadaver and split in 2 times, producing four tendons per one shoulder, for a total of 24 specimens. Two suture configurations (UU, MA) were randomized and checked on each set of tendons. Specimens were cyclically loaded under force control between 5 and 30 N at 0.25 Hz for fifty cycles. Each specimen was loaded to failure under displacement control at 1 mm/sec. Cyclic elongation, peak to peak displacement, stiffness, ultimate tensile load, mode of failure were checked. Results: No significant difference was found between two suture configuration with respect to peak to peak displacement, cyclic elongation, and stiffness. With regard to ultimate failure load, there were no significant difference statistically between the UU suture and modified MA suture (109.4 N, 110.6 N). The most common mode of failure between both sutures was suture pull-out through the tendon. Conclusion: The UU suture and modified MA suture produced similar biomechanical properties.

Purpose: The various suture techniques can be utilized in order to maximize the keratinized tissue healing around dental implants. The aim of this study is to compare the soft tissue healing pattern between two different suture techniques after implant placement. Materials and Methods: 15 patients with 18 implants were enrolled in this study. Simple implant placement without any additional bone graft was performed. Two different suture techniques were used to tug in the mobilized flap near the healing abutment after paramarginal flap design. Digital intraoral scan was performed at baseline, post-operation, stitch out, and 3 months after operation. The scan data were aligned using multiple points such as cusp, fossa of adjacent teeth, and/or healing abutment. After subtracting scan data at baseline with other time-point results, closed space indicating volume increment of peri-implant mucosa was selected. The volume of the close space was measured in mm³. The volume between two suture techniques at three time-points was compared using nonparametric rank-based analysis. Results: Healing was uneventful in both groups. Both suture technique groups showed increased soft tissue volume immediately after surgery. The amount of volume increment significantly decreased after 3 months (P < 0.001). Flap folding suture group showed higher median of volume increment than interrupted suture group after 3 months without any statistical significance (P > 0.05). Conclusion: After paramarginal flap reflection, the raised flaps stabilized by flap folding suture showed relatively higher volume maintenance after 3-month healing period. However, further studies are warranted.
