Abstract
Introduction: Surgery for colorectal cancer consists of resection in the tumor block and ? 12 regional lymph nodes, it must include the ligation of the main vessel of the segment. This set of techniques can be laparoscopically performed and the objective of this study is to present the results of a single center with the surgical laparoscopic surgical approach in a group of patients diagnosed with
colorectal cancer.
Methods: In the Department of Oncological Surgery of the Hospital "Solón Espinosa Ayala" of Quito, a descriptive, retrospective study was carried out during the period from January 2009 to September 2012. All cases of patients with the initial diagnosis of colorectal tumor, previous examinations, tumor markers, chest-abdomen tomography, and those that have been developed as a colonoscopic diagnostic method will be analyzed. We excluded patients with neoplasms of secondary origin, with incomplete clinical histories that make analysis impossible. The variables sex, age, tumor location, histopathological diagnosis and perioperative morbidity will be studied. The statistical analysis
performed was descriptive).
Results: 25 patients with mediastinal tumor diagnosis were evaluated, with an average age of 61 years. There were 15 women (60 %). The postoperative histopathological study had 10 cases (40 %) with moderately differentiated adenocarcinoma, 7 cases (28 %) with well differentiated
adenocarcinoma. Resection of ?12 regional lymph nodes was performed in 15 cases (75 %). In 13 cases (52 %) they received adjuvant. 1 case required conversion to open surgery. Morbidity occurred in 2 cases (8 %) with fistula and 1 case (4 %) pneumonia.
Conclusion: Adenocarcinoma was the most frequent malignant tumor in this series. Laparoscopic surgical management of colored tumors had a low complication rate and a surgical approach in 75 % of the cases with resection of more than 12 peritumoral lymph nodes.
