Carcinoid tumors. Retrospective review of 25 patientsBackground: The incidence of carcinoid tumors (CT) has increased in the last fi ve decades. These supposedly benign tumors may not always behave as such. The largest series of CT show that the most common primary tumor site (appendiceal) changed over the years. Aim: To evaluate the management of gastrointestinal CT at the National Cancer Institute from 2000 to 2006, describe their anatomic location and estimate disease specifi c survival. Material and Methods: Review of the database of the Cancer Committee, during a period of 7 years, looking for patients with a pathological diagnosis of CT, whose clinical records were analyzed. Results: The records of 25 patients with gastrointestinal CT, aged 18 to 79 years (19 females) were analyzed. Five years disease specifi c survival was 91.1%. The most common location was appendiceal in 56% of cases, with a 5 years disease specifi c survival of 100%. Right hemicolectomy was performed in seven patients with appendiceal carcinoid. Other seven patients only underwent appendectomy. Five years disease specifi c survival was 100% in both groups. Conclusions: The appendix is still the most common location of CT in this series and long term survival is acceptable.
Factors associated with early morbidity in laparoscopic colorectal surgery Introduction: Different factors have been associated with increased risk of complications in laparoscopic colorectal surgery. The aim of this study is to identify these factors in our series. Method: Retrospective cohort. All patients undergoing laparoscopic colorectal surgery between January 2000 and June 2012 were included. Patients who had postoperative complications until 30 days postoperatively were identified and analyzed by univariate and multivariate logistic regression. A p value less than 0.2 was used was used as a criteria for entry into the multivariate model. Results: The series consists of 848 patients with a median age of 58 ± 22 years. Main surgical indications were: neoplasia (42.3%), diverticular disease (27.8%) and inflammatory bowel disease (8.8%). Most frecuently-performed procedures were: sigmoidectomy (39.5%), anterior resection of the rectum (13.4%), right hemicolectomy (13%) and total colectomy (8.7%). On univariate analysis, factors associated with complications were age over 75 years (OR 1.82, 95% CI 1.02 to 3.25) and red blood cell transfusion (OR 8.47, 95% CI 3.69 to 19.43). On multivariate analysis, red blood cell transfusion (OR 7.9 95% CI 1.78 to 35.88) and ASA III or IV (OR 3.26 95% CI 1.01 to 17.23) were independent factors associated with postoperative complications. Conclusion: Intraoperative red blood cell transfusion and ASA score III or IV are independent risk factors associated with complications in laparoscopic colorectal surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
