    (2016) Elena Molina, Maria; Bellolio, Felipe; Klaassen, Julieta; Gomez, Javier; Villalon, Constanza; Francisco Guerra, Juan; Zuniga, Alvaro
    Background: In patients suffering intestinal failure due to short bowel, the goal of an Intestinal Rehabilitation Program is to optimize and tailor all aspects of clinical management, and eventually, wean patients off lifelong parenteral nutrition. Aim: To report the results of our program in patients suffering intestinal failure. Patients and Methods: A registry of all patients referred to the Intestinal Failure unit between January 2009 and December 2015 was constructed. Initial work up included prior intestinal surgery, blood tests, endoscopic and imaging studies. Also demographic data, medical and surgical management as well as clinical follow-up, were registered. Results: Data from 14 consecutive patients aged 26 to 84 years (13 women) was reviewed. Mean length of remnant small bowel was 100 cm and they were on parenteral nutrition for a median of eight months. Seven of 14 patients had short bowel secondary to mesenteric vascular events (embolism/thrombosis). Medical management and autologous reconstruction of the bowel included jejuno-colic anastomosis in six, enterorraphies in three, entero-rectal anastomosis in two, lengthening procedures in two, ileo-colic anastomosis in one and reversal Roux-Y gastric bypass in one. Thirteen of 14 patients were weaned off parenteral nutrition. Conclusions: Our Multidisciplinary Intestinal Rehabilitation Program, allowed weaning most of the studied patients off parenteral nutrition.

    Splenic rupture following colonoscopy
    (BAISHIDENG PUBLISHING GROUP INC, 2008) Francisco Guerra, Juan; San Francisco, Ignacio; Pimentel, Fernando; Ibanez, Luis
    Colonoscopy is a safe and routinely performed diagnostic and therapeutic procedure for different colorectal diseases. Although the most common complications are bleeding and perforation, extracolonic or visceral injuries have also been described. Splenic rupture is a rare complication following colonoscopy, with few cases reported. We report a 60-year-old female who presented to surgical consultation 8 h after a diagnostic colonoscopy. Clinical, laboratory and imaging findings were suggestive for a massive hemoperitoneum. At surgery, an almost complete splenic disruption was evident, and an urgent splenectomy was performed. After an uneventful postoperative period, she was discharged home. Splenic injury following colonoscopy is considered infrequent. Direct trauma and excessive traction of the splenocolic ligament can explain the occurrence of this complication. Many times the diagnosis is delayed because the symptoms are due to colonic insufflation, so the most frequent treatment is an urgent splenectomy. A high index of suspicion needs an early diagnosis and adequate therapy. (C) 2008 The WJG Press. All rights reserved.

    Trasplante hepático: Evolución, curva de aprendizaje y resultados después de los primeros 300 casos
    (2019) Francisco Guerra, Juan; Luis Quezada, Jose; Cancino, Alejandra; Arrese, Marco; Wolff, Rodrigo; Benitez, Carlos; Carlos Pattillo, Juan; Cristobal Gana, Juan; Concha, Mario; Cortinez, Luis; Vera, Magdalena; Miranda, Paula; Rubilar, Francisco; Troncoso, Andres; Briceno, Eduardo; Dib, Martin; Jarufe, Nicolas; Martinez, Jorge
    Background: Liver transplantation (LT) is an option for people with liver failure who cannot be cured with other therapies and for some people with liver cancer. Aim: To describe, and analyze the first 300 LT clinical results, and to establish our learning curve. Material and Methods: Retrospective cohort study with data obtained from a prospectively collected LT Program database. We included all LT performed at a single center from March 1994 to September 2017. The database gathered demographics, diagnosis, indications for LT, surgical aspects and postoperative courses. We constructed a cumulative summation test for learning curve (LC-CUSUM) using 30-day post-LT mortality. Mortality at 30 days, and actuarial 1-, and 5-year survival rate were analyzed. Results: A total of 281 patients aged 54 (0-71) years (129 women) underwent 300 LT. Ten percent of patients were younger than 18 years old. The first, second and third indications for LT were non-alcoholic steatohepatitis, chronic autoimmune hepatitis and alcoholic liver cirrhosis, respectively. Acute liver failure was the LT indication in 51 cases (17%). The overall complication rate was 71%. Infectious and biliary complications were the most common of them (47 and 31% respectively). The LC-CUSUM curve shows that the first 30 patients corresponded to the learning curve. The peri-operative mortality was 8%. Actuarial 1 and 5-year survival rates were 82 and 71.4%, respectively. Conclusions: Outcome improvement of a LT program depends on the accumulation of experience after the first 30 transplants and the peri-operative mortality directly impacted long-term survival.
