Safety of monofilament barbed sutures with a helical and an oppositional barbes design in the single anastomosis formation during laparoscopic mini-gastric bypass

Introduction. The available literature lacks information on the advantages of different knotless tissue fixation devices for the laparoscopic intracorporeal gastroenterostomy, making their informed choice difficult.
The purpose of the study. To evaluate the short-term clinical outcomes of the monofilament barbed sutures with a helical and an oppositional barbes design in the single anastomosis formation during laparoscopic mini-gastric bypass (LMGB).
Material and methods. Knotless tissue fixation devices were used for manual intracorporeal formation of gastrojejunal anastomosis during LMGB in 80 patients: with a helical barbes design – in the first group (38 patients) and with an oppositional – in the second group (42 patients). No significant differences were detected in the baseline demographic characteristics, body mass index, comorbidity and the frequency of previous abdominal surgeries between groups.
Results. There were no differences in total intraabdominal operation time and the duration of the gastrojejunal anastomosis formation in the clinical groups. Gastrojejunostomy using knotless tissue fixation devices, on average, took up to 24,4% of the operation time. Intraoperatively, only incidents of severity grade 1 (Satava-Kazaryan classification) were recorded with a frequency of 5,3–7,1 % (р=0,999). Postoperatively, minor complications (severity grade 1 of the Clavien-Dindo-Strasberg system) were recorded in 7,9 % and 11,9 % of patients in the first and second clinical groups, respectively (p=0,715).
Conclusion. This study revealed no significant differences between short-term clinical outcomes of the monofilament barbed sutures with a helical and an oppositional barbes design in the gastroenteric anastomosis manual formation during LMGB.
