| Objective:By analyzing the clinical effects of elective surgery at different times after stent placement in patients with left-sided obstructive colorectal cancer,we hope to provide a benchmark for choosing the best timing of surgery for patients with left-sided obstructive colorectal cancer.In order to achieve better surgical results in clinical practice and improve the quality of life of patients after surgery.Methods: The clinical data of 89 patients who underwent elective radical surgery for left obstructive colorectal cancer after SEMS placement in the Fourth Affiliated Hospital of China Medical University and the Fourth People’s Hospital of Shenyang from September 2017 to October 2021 were retrospectively analyzed.According to the different operation intervals between stent placement and elective surgery,the patients were divided into two groups,A and B,group A（SEMS placement time < 14 days）with 46 cases,and B group（SEMS placement time ≥ 14 days）with 43 cases,Statistical processing using SPSS 25.0 for data analysis.Measurement data were expressed as mean ± standard deviation（（?） ± S）,t-test was used for comparison between two groups,enumeration data was described by case number and rate（%）,and c~2 test was used for comparison between two groups.P < 0.05 was considered statistically significant.The operation-related conditions,perioperative conditions（including operation time,intraoperative blood loss,number of lymph node dissections,postoperative hospital stay,postoperative first defecation time）and postoperative complications were compared between the two groups.Results: A total of 89 patients were included in this study,with an average age of65.16±4.93 years.Among them,54 were male patients and 35 were female patients.Among the 89 patients,46 patients belonged to group A.The tumor location included17 patients in descending colon,21 patients in sigmoid colon,and 8 patients in high rectum.The other 43 patients belonged to group B.The tumor location in group B included 14 patients in descending colon and 18 patients in sigmoid colon.,11 people with high rectum.1.Comparison of the perioperative conditions between the two groups: the operation time,intraoperative bleeding and the number of dissected lymph nodes in group B（radical tumor resection after 14 days or more after colon stent placement）were better than those in group A（Colonic stent placement less than 14 days after radical tumor resection）,the first defecation time and postoperative hospital stay in group B were shorter than those in group A,and the differences in the above indicators were statistically significant（P < 0.05）.2.Comparison of postoperative conditions between the two groups: the postoperative complications in group B were less than those in group A,and the difference was statistically significant（P < 0.05）.Conclusion: Patients in group B（who underwent radical tumor resection within14 days after colon stent placement）and patients in group A（who underwent radical tumor resection less than 14 days after colon stent placement）had perioperative related indicators（operation time,There were statistically significant differences in intraoperative blood loss,number of lymph node dissections,postoperative first bowel movement time,postoperative hospitalization time）and postoperative complications.That is,patients in group B can recover better and faster in their intestinal and physical conditions.The results of this study suggest that patients with obstructive left-sided colorectal cancer who undergo colonic stent placement for 14 days or more after radical tumor resection have better clinical effects and are more conducive to the recovery of patients,and are worthy of clinical recommendation.. |
