![]() ![]() ![]() Pathological examination was performed by pathology department of our hospital. ![]() The specimens were dissected by the surgeon after operation, and all the accessible lymph nodes were routinely submitted for examination. Naked the intestine 10 cm proximal of the tumor and 5 cm at the distal of the tumor and transected, removed the tumor specimen, and anastomosed by circular stapler. Ligate the artery after being clamped by Hem-O-lock at the root of IMA and IMV about 2 cm, resected IMA-LNs. Separate the root of the naked inferior mesenteric artery and clean the lymph nodes at the root of the inferior mesenteric artery. Mobilize the sigmoid colon along the inferior mesenteric artery, find the Toldt’s fascia, and mobilize the lateral peritoneum. General anesthesia, adjust the patient’s position, and laparoscopic exploration. The study was approved by the Research Ethics Committee of Renji Hospital and carried out in accordance with the ethical standards formulated in the Helsinki Declaration. Routine MR examinations were performed before surgery, and clinical TN staging was performed. Inclusive criteria: no distant metastasis, no obstruction, no emergency surgery, no radiotherapy or chemotherapy and other anti-tumor treatment, no history of other malignant tumors, and no colorectal multiple primary cancer. 2020, we performed a retrospective analysis of patients who were eligible to receive proctectomy surgery in the Department of Gastrointestinal Surgery, Renji Hospital, Shanghai Jiao Tong University School of Medicine. We should choose the appropriate surgical methods to achieve better oncological results and reduce the incidence of postoperative complications.įrom Jan. Conclusionĭistance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs. Multivariate analysis showed that distance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs. Positive IMA-LNs were associated with distance from anal verge, CEA, pathological type, differentiation, nerve invasion, T stage, and N stage. There were 29 cases with IMA-LN metastasis the metastasis rate was 5.98% (29/485). ResultsĪ total of 485 cases were included in this study. Clinical features of patients, including gender, age, BMI, tumor size, pathological type, differentiation, nerve invasion, lymph nodes, tumor marker, and pathological examinations, were analyzed. MethodsĤ85 rectal cancer patients underwent proctectomy surgery were collected in this study. This study aimed to explore the pathological characteristics of lymph nodes around inferior mesenteric artery in rectal cancer and its risk factors and its impact on tumor staging. ![]()
