- ItemGastrectomía laparoscópica en cáncer gástrico: Experiencia preliminar(2007) Escalona, Alex; Pérez Blanco, Gustavo Adolfo; Crovari Eulufi, Fernando; Boza, Camilo; Pimentel Muller, Fernando; Devauda, Nicolás; Guzmán Karadima, Sergio; Ibáñez Anrique, LuisBackground: The development of the laparoscopic surgery has allowed its incorporation to the surgical treatment of gastric cancer. Aim: To evaluate the feasibility and safety of laparoscopic gastrectomy in gastric cancer in our institution. Patients and methods: Prospective data in four patients who underwent laparoscopic gastrectomy for gastric cancer from May to August of 2005 was reviewed. Demographic data, clinical characteristics and postoperative results were registered. Patients were staged according to TNM-AJJC staging system. Results: Four patients aged 48 to 80 years (three males), underwent a completely laparoscopic R0 gastrectomy with lymph node dissection. Two patients underwent total gastrectomy. A subtotal Billroth II gastrectomy was performed in the other two patients. The mean operative time was 260 minutes (Range 180-330). There were no conversions to open surgery. The mean postoperative hospital stay was 6.5 days (Range 6-7 days). There were no complications. According to pathology, one patient presented carcinoma in stage IA, two patients in stage IB and one patient in stage IIIB. The mean number of lymph nodes dissected was 40 (Range 35-54). Conclusions: Laparoscopic gastrectomy is a feasible procedure with good postoperative results in this preliminary experience.

En la mayoría de los casos, el tratamiento es quirúrgico, sin embargo, este se asocia a una alta morbilidad. El desarrollo de la cirugía mí
- ItemSobrevida alejada de pacientes operados por cáncer gástrico incipiente(2008) Butte Barrios, Jean Michel Domingo; Torres Montes, Paula Javiera; Viviani García, Paola; Duarte, Ignacio; Crovari Eulufi, Fernando; Guzmán Karadima, Sergio; Cabrera Valenzuela, José Roberto; Pedemonte Trewhela, Juan Cristóbal; Llanos López, OsvaldoBackground: Early gastric cancer involves mucosa and submucosa, independent of lymph node involvement. Radical gastrectomy is the standard treatment. Aim: To assess long term survival of patients operated for an early gastric cancer. Material and methods: Retrospective Rev iew of medical and pathology records of patients subjected to a gastrectomy for an early gastric cancer, between 1975 and 2002. All were treated using a standardized protocol and staged according to 2002 TNM classification of the American Joint Committee of Cáncer (AJCC). Demographic and pathologic features, operation performed and long term survival were recorded. Survival was analyzed using Kaplan-Meier method. Results: The series is comprised by 64 males and 41 females aged 61 + 1 years. Tumor was located in the upper third of the stomach on 33 subjects and a total gastrectomy was performed in 53. Pathology showed an intestinal type adenocarcinoma in 82 and a diffuse type in 23. In patients with involvement of mucosa and submucosa, 24 ± 14 and 22 ± 14 lymph nodes were excised, respectively. Lymph node involvement was present in 8% and 22% of patients with involvement of mucosa and submucosa, respectively. Five years survival was 94% and 78% in patients without and with lymph node involvement, respectively. Survival among patients in stage IA and IB was 94% and 76%, respectively. Multivariate analysis showed that the lymph node involvement was an independent mortality risk factor. Conclusions: Total gastrectomy in patients with early gastric cancer is associated with a good survival. Lymph node involvement is a mortality risk factor.
