    11 beta-Hydroxysteroid Dehydrogenase Type 1 is Overexpressed in Subcutaneous Adipose Tissue of Morbidly Obese Patients
    (SPRINGER, 2009) Munoz, Rodrigo; Carvajal, Cristian; Escalona, Alex; Boza, Camilo; Perez, Gustavo; Ibanez, Luis; Fardella, Carlos
    11 beta-Hydroxysteroid dehydrogenase type 1 (11 beta-HSD1) enzyme catalyzes interconversion of inactive cortisone to active cortisol. Its expression in adipose tissue has been associated with obesity and some of its metabolic disorders. Controversies regarding which fat depots [subcutaneous adipose tissue (SAT) or visceral adipose tissue (VAT)] have higher expression still remain. The aim of this work was to evaluate 11 beta-HSD1 expression in SAT and VAT of obese patients and evaluate its association to metabolic features of metabolic syndrome.

    Gastrectomía 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, Luis
    Background: 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.

    Objectives: Natural orifice translumenal endoscopic surgery (NOTES) is evolving as a promising alternative for abdominal surgery. IMTN Registry was designed to prospectively document early results of natural orifice surgery among a large group of clinical cases. Methods: Sixteen centers from 9 countries were approved to participate in the study, based on study protocol requirements and local institutional review board approval. Transgastric and transvaginal endoscopic natural orifice surgery was clinically applied in 362 patients. Intraoperative and postoperative parameters were prospectively documented. Results: Mean operative time for transvaginal cholecystectomy was 96 minutes, compared with 111 minute for transgastric cholecystectomy. A general complication rate of 8.84% was recorded (grade I-II representing 5.8%, grade III-IV representing 3.04%). No requirement for any analgesia was found in one fourth of cholecystectomy and appendectomy patients. Conclusions: Results of clinical applications of NOTES in the IMTN Study showed the feasibility of different methods of this new minimally invasive alternative for laparoscopic and open surgery.

    Laparoscopic Roux-en-Y gastric bypass versus laparoscopic sleeve gastrectomy: a case-control study and 3 years of follow-up
    (ELSEVIER SCIENCE INC, 2012) Boza, Camilo; Gamboa, Cristian; Salinas, Jose; Achurra, Pablo; Vega, Andrea; Perez, Gustavo
    Background: Laparoscopic sleeve gastrectomy (LSG) has become a popular surgical procedure among bariatric surgeons. Few studies have compared the efficacy of the procedure to laparoscopic Roux-en-Y gastric bypass (LRYGB). We performed a case-control study to assess the surgical results, weight progression, and remission of co-morbid conditions.
