Evaluation of pathological outcomes and surgical radicality after laparoscopic resection of colon adenocarcinoma

Aim The aim of the present study was to assess the efficacy, pathological outcomes, and oncologic radicality after laparoscopic resection of colon adenocarcinoma. Patients and methods The study was conducted on 30 consecutive patients who had undergone laparoscopic resection of colon adenocarcinoma in the Surgical Oncology Unit, Department of Surgery, Faculty of Medicine, Alexandria University, Egypt (with exclusion criteria of patients with history of extensive abdominal surgery and obese patients with BMI>45kg/m(2) and metastatic colorectal cancer). Results The mean age of the studied cases was 55.6 years, 53% of the studied cases had BMI more than 30kg/m(2), 33% of the cases were sigmoid cancer, half of the cases (50%) were T2, and almost the other half were T3. The average procedure duration in the study was 190 min, 23% of the cases (seven cases) have been converted to open surgery, and the mean number of lymph nodes harvested was 13.5, with a range from 6 to 22. The analysis for the number of lymph nodes harvested by BMI showed that as the BMI increases, the likelihood for harvesting 12 lymph nodes or less increases as well. The Cramer's V test statistic (a measure of the degree of association between the two categorical variables 'lymph nodes harvested' and 'BMI') yielded a very strong correlation (value of '0.434'). Conclusion Laparoscopy is a reliable method in colon cancer resection regarding surgical radicality, pathological outcomes, and efficacy.
