Robotic surgery at ABC Medical Center: first 500 procedures experience.

Background: Robotic surgery is a technological advance that is used in multiple surgical specialties in the world. Its acceptance in various areas has been supported by comparative studies with laparoscopic surgery and open surgery.

Objective: To document the robotic surgery program initial experience in a private hospital of Mexico City by analyzing its results and complications.

Rectal cancer: diagnosis, screening and treatment.

Rectal cancer is one of the primary malignant neoplasms occurring in Mexican patients of reproductive age. Unfortunately, randomized studies in rectal cancer do not exist as they do with well-recognized colon cancer. We must individualize the epidemiology, risk factors, diagnostic approach, staging and treatment because management is different in rectal cancers affecting the mid- and lower third of the rectum than in the upper third and in colon cancers.

[Laparoscopic appendectomy. Present situation. ABC medical center experience during the last five years].

Objective: To compare the diagnostic and therapeutic accuracy of laparoscopic appendectomy versus open appendectomy.

Background Data: Appendectomy is the treatment of choice for acute appendicitis. Open Appendectomy (OA) has its complications rates (10-20%) and negative explorations in young women are about 25-30%.

[Ileocecal valve lipoma. Case report and review of the literature].

Background: Lipomas are the most frequent benign tumors of the digestive tract and 50% are localized in the colon. Most are found submucosally and may vary in their incidence, localization, symptoms and pathogenesis, making diagnosis difficult. We undertook this study to learn the different presentations of an ileocecal valve (ICV) lipoma and conduct a review of the literature due to this uncommon location.

[Intraoperative endoscopy in laparoscopic fundoplications].

Background: Laparoscopic fundoplications are the standard surgical treatment of patients with gastroesophageal reflux disorder. Adequate technique is the most important outcome factor. There is no standardized method to evaluate the procedure itself.

[Refundoplication for failed antireflux surgery. Experience in sixteen cases].

Background: We undertook this study to identify the main causes leading to a failed funduplication and to determine the feasibility and effectiveness of reoperation by laparoscopic approach.

Methods: A retrospective and descriptive study was carried out with a review of patient charts. Patients were reoperated for failed antireflux surgery between January 1999 and September 2004.
