Abstract

Background and Objectives: Left-sided colon cancer has many features that differ from right-sided colon cancer in both pathology and histopathology. Laparoscopic surgery for left-sided colon cancer also has its own characteristics that need to be studied and discussed. Methods: This is a retrospective study of patients undergoing laparoscopic left-sided colectomy for the treatment of primary adenocarcinoma of the colon with no distant metastases. Results: During the period from January 2017 to December 2022, we collected on 72 patients who were eligible for the study. The mean age of the study group was 62.72 ± 12.35 years old. Of these, 61.1% are male and 38.9% are female. Tumor locations included 13 (18.1%) splenic flexure colon, 11 (15.3%) descending colon and 48 (66.6%) sigmoid colon. The average surgery time was 154.79 ± 38.57 minutes. Surgical techniques included 12 (16.7%) left high colectomy, (22.2%) left-sided colectomy and 44 (61.1%) sigmoidectomy. The average blood loss was 25.3 ± 8.1ml, the rate of intraoperative complications was 2.8%. There were 16.7% anastomosis of the transverse colon and sigmoid colon by hand sutures and 60 (83.3%) anastomosis of the colon and rectum by EEA instrument. The average number of lymph nodes removed was 14.6 ± 3.5 lymph nodes and 42 patients had lymph node metastasis. The rate of postoperative complications was 19.4%, including anastomosis fistula, anastomosis bleeding, intestinal obstruction, pancreatitis, pneumonia and surgical site infection. There were 79.2% of patients discharged from the hospital with good results. The estimated overall survival after surgery at 48 months was 96.8%. Conclusion: Laparoscopic left-side colectomy for colon cancer has shown that in addition to the advantages about early results, it has met the oncological requirements.
