Abstract:Objective To investigate the feasibility and safety of continuous suture in laparoscopic common bile duct exploration of primary suture.Methods 70 patients with calculus of common bile duct treated from October 2018 to September 2022 were selected. Both groups underwent laparoscopic common bile duct exploration and were divided into the intermittent suture group (35 cases) and the continuous suture group (35 cases) according to different suture methods. Both groups received the same postoperative treatment, they were followed up for 6 months. The operation-related indexes, postoperative recovery indexes, quality of life before and 14 days after operation, inflammatory reaction and stress response before and 3 days after operation, complications and residual and recurrence of stones during follow-up were compared between the two groups.Results The suture time of common bile duct, operation time, hospitalization time and drainage tube removal days of the continuous suture group were shorter than those of the intermittent suture group, and the intraoperative blood loss less than that of the intermittent suture group, visual analogue scale (VAS) were lower than that of the intermittent suture group, the differences were statistically significant (P < 0.05). The scores and total scores of gastrointestinal quality of life index (GIQLI) of the two groups 14 days after operation were higher than those before operation, and the continuous suture group was higher than that of the intermittent suture group. The levels of serum interleukin-6 (IL-6), procalcitonin (PCT), adrenocorticotropic hormone (ACTH), cortisol (Cor), norepinephrine (NE), C- peptide (C-P) and peripheral blood neutrophil (NEUT) 3 days after operation of the two groups were higher than those before operation, while the continuous suture group was lower than that of the intermittent suture group, and the differences were statistically significant (P < 0.05). There were no significant differences in the total incidence of complications, residual rate of stones and recurrence rate of stones between the two groups (P > 0.05).Conclusion The application of continuous suture in primary suture of laparoscopic common bile duct exploration can improve operation-related indexes, relieve postoperative inflammatory reaction and stress response, and improve the quality of life of patients, without increasing the risk of stone residue and recurrence.
