Abstract: Objective To introduce the specific operation method and application value of applying a single absorbable suture for manual bowel anastomosis.
Methods From July 2017 to June 2018, a total of 224 patients underwent manual bowel anastomosis due to abdominal and pelvic neoplastic diseases; they were divided into two groups according to different methods of anastomosis, 98 cases in the manual group, with a single absorbable suture. 126 patients in the instrument group, with silk thread reinforcement additionally. The anastomosis time, anastomotic hemorrhage, anastomotic stenosis, and anastomotic cost were compared between the two groups, and the application value of single absorbable suture interactive inversion suture in manual bowel anastomosis was statistically analyzed.
Results All 224 patients were successfully completed the operation. The postoperative anastomotic leakage in the manual group and the instrument group were 3 and 15 respectively, the anastomotic bleeding was 1 and 19, and the anastomotic stenosis was 0 and 13 cases. The operation time was (3.2±1.1) min and (5.5±2.1) min, and the cost of anastomosis was (53±13.2) yuan and (2753±899.2) yuan respectively. The difference between the two groups was statistically significant.
ConclusionUsing  a single absorbable suture in interactive inversion suture is a safe and reliable method in manual bowel anastomosis, with fewer complications associated with anastomosis, which is beneficial to reduce the operation time and reduce the cost of hospitalization.
