Abstract:
Objective To investigate the clinical efficacy of Da Vinci robot-assisted radical resection for right colon cancer.Methods The retrospective cross-sectional study was conducted.The clinical data of 85 patients with right colon cancer who were admitted to the First Hospital Affiliated to Army Medical University from August 2013 to February 2019 were collected.There were 56 males and 29 females,aged from 29 to 84 years,with an average age of 60 years.All patients underwent Da Vinci robot-assisted radical resection of right colon cancer,named right hemicolon D3 + complete mesocolic excision,and received infection prevention and total parenteral nutrition treatment after surgery.According to clinical pathological staging of guideline issued by National Comprehensive Cancer Network,patients underwent postoperative chemotherapy within 1 year after surgery.Observation indicators:(1) treatment status;(2) postoperative pathological examination;(3) follow-up.Follow-up was conducted using outpatient examination,telephone interview and mail every 3 months within 1 year after surgery,every 6 months from 1 to 3 years after surgery,and once a year from 3 to 5 years after surgery up to March 2019.The postoperative tumor metastasis and survival of patients were obtained.Measurement data with normal distribution were represented as Mean±SD,and measurement data with skewed distribution were described as M (range).Count data were expressed as absolute number.Survival rates were calculated using life-table method.Results (1) Treatment status:85 patients underwent Da Vinci robot-assisted right hemicolon D3 + complete mesocolic excision successfully.The operation time,volume of intraoperative blood loss,time for postoperative outof-bed activities,time to recovery of gastrointestinal function,time to liquid diet intake were (178±28) minutes,(85±33) mL,(2.9± 1.8) days,(3.1 ± 2.7) days,(3.9± 1.9) days,respectively.There was no perioperative death.Eleven patients had postoperative complications including 5 of anastomotic leakage,2 of anastomotic bleeding,2 of pulmonary infection,1 of gastric emptying disorder and 1 of incomplete intestinal obstruction;they were cured and discharged after conservative treatment.All the 85 patients received postoperative infection prevention and total parenteral nutrition support,including 64 receiving systemic intravenous chemotherapy with 6 -8 cycles of FOLFOX or XELOX,7 receiving 6-8 cycles of oral capecitabine,and 14 receiving no chemotherapy.(2) Postoperative pathological examination:the number of harvested lymph nodes was 20± 11 and 25 had lymph node metastasis.The length of proximal and distal cutting edge of the specimens was (16±5) cm and (9±5)cm,respectively.There was no cancerous cell on the cutting edge.High-differentiated adenocarcinoma,moderatedifferentiated adenocarcinoma,moderate-differentiated tubular adenocarcinoma,low-differentiated adenocarcinoma,mucinous adenocarcinoma,tubular combined with mucinous adenocarcinoma were detected in 2,40,14,16,9,4 patients,respectively.There were 8,28,24,5,12,8 patients in Ⅰ stage,Ⅱ A stage,Ⅱ B stage,Ⅱ C stage,ⅢB stage,Ⅲ C stage of TNM staging,respectively.(3) Follow-up:85 patients were followed up for 1-67 months,with a median follow-up time of 19 months.During the follow-up,1 of 85 patients had liver metastasis at 14 months after surgery and had survived after radiofrequency ablation treatment up to the end of follow-up.Three cases died of abdominal tumor metastases,1 of which in Ⅱ C stage died at 32 months after surgery,1 in Ⅲ B stage died at 4 months after surgery and 1 in Ⅲ B stage died at 16 months after surgery.The 1-,3-year overall survival rates were 97.1％ and 94.0％,respectively.Conclusion Da Vinci robot-assisted radical resection of right colon cancer is safe and feasible,with good short-and long-term outcomes.
