Background
The aim of this study was to investigate the safety and efficacy of self-retaining barbed sutures in comparison with monofilament clip-fixated sutures for rectal wall closure in transanal endoscopic microsurgery.
Methods
Horizontal full-thickness wall defects (3.5 cm) of cattle rectal specimens were closed via transanal endoscopic microsurgery using a monofilament suture with clips at the end (Surgipro® 2/0; Covidien, Mansfield, MA, USA, n = 25) or a self-retaining barbed suture (V-Loc™ 180 3/0; Covidien, Mansfield, MA, USA, n = 25). The primary endpoint was the pneumatic leakage pressure of the suture line. As a secondary endpoint, suture time was evaluated.
Results
The median pneumatic leakage pressure for barbed sutures was 45.5 mbar (range 17–106 mbar) and 33.5 mbar (range 19–106 mbar) for monofilament sutures (p = 0.58). A pneumatic leak at a critical pressure below 25 mbar occurred in 3 cases with barbed sutures and in 7 cases with monofilament sutures (p = 0.29). Median suturing time [19:25 min:s (range 12:00–33:30) vs. 20:41 (17:00–28:33), p = 0.23] did not differ between the two groups.
Conclusions
Barbed sutures display the same bursting pressure as monofilament sutures and their use for rectal wall closure seems feasible.
