ABSTRACT
Objective@#To investigate the application value of parallel and cross-to-overlap anastomosis method (PCOA) in three-dimensional (3D) laparoscopic radical resection of right hemicolon cancer.@*Methods@#The retrospective cross-sectional study was conducted. The clinicopathological data of 138 patients who underwent 3D laparoscopic radical resection of right hemicolon cancer at Henan Provincial People′s Hospital between July 2016 and July 2019 were collected. There were 83 males and 55 females, aged from 30 to 76 years, with a median age of 64 years. All the 138 patients with right hemicolon tumors were diagnosed as malignant tumors by enteroscopy and pathological examination before operation. The lymph node dissection and radical resection of right hemicolon cancer were performed according to the 9th edition of Japanese General Rules for Cancer of Colon, Rectum and Anus of the Japanese Colorectal Cancer Association. Observation indicators (1) surgical situations; (2) postoperative conditions; (3) follow-up. Follow-up was conducted by outpatient examination or telephone interview to detect survival of patients and tumor recurrence and metastasis up to September 2019. Measurement data with normal distribution were represented as Mean±SD. Measurement data with skewed distribution were represented as M (range). Count data were represented as percentages or absolute numbers.@*Results@#(1) Surgical situations all the 138 patients underwent 3D laparoscopic radical resection of right hemicolon cancer using PCOA to reconstruct digestive tracts, without conversion to open surgery. The operation time, time for PCOA, and volume of intraoperative blood loss was (151.0±54.0)minutes, (20.1±2.0)minutes, and (60±21)mL. (2) Postoperative situations the time to first flatus, time to semi-liquid food intake, length of auxiliary incision, and incidence rate of postoperative complications were (2.5±0.4)days, (4.0±1.3)days, (3.0±0.2)cm, and 3.62%(5/138), respectively. Of the 5 patients with postoperative complications, 1 patient with intestinal obstruction was cured after conservative treatment including gastrointestinal decompression and nutritional support, 1 patient with anastomotic leakage was cured after conservative treatment including gastrointestinal decompression, local patency drainage, infection control and nutritional support, 1 patient with ascites and abdominal infection was cured after computed tomography-guided percutaneous catheter drainage, 1 patient with incisional infection was cured by controlling infection, strengthening dressing changes, local irrigation and drainage, 1 patient with pulmonary infection was cured after anti-infective treatment.The number of lymph nodes dissected after surgery, duration of postoperative hospital stay, and hospital expenses were 19±8, (7.2±4.1)days, and (4.8±1.4)×104 yuan. All the 138 patients were confirmed as colonic adenocarcinoma by postoperative pathological examination, including 27 cases of poorly differentiated adenocarcinoma, 92 cases of moderately differentiated adenocarcinoma, 10 cases of highly differentiated adenocarcinoma, and 9 cases of mucinous adenocarcinoma. (3) Follow-up 133 of 138 patients were followed up for 2-38 months, with a median follow-up time of 18 months. During the follow-up, 2 patients died, 1 of which was detected multiple liver metastases at postoperative 16 months and died at postoperative 21 months, and the other was detected multiple liver metastases at postoperative 20 months and died at postoperative 24 months. Eight patients had distant metastasis, including 5 cases of liver metastasis, 1 case of lung metastasis, and 2 cases of abdominal metastasis. The 10 patients with death and tumor metastasis were confirmed as stage Ⅲ by postoperative pathological examination, and the other 123 patients were generally in good condition.@*Conclusion@#PCOA is safe and effective for 3D laparoscopic radical resection of right hemicolon cancer.
