    Arteriovenous malformation of the pancreas: Report of a case
    (2007) Butte, Jean M.; Francisco, Ignacio F. San; Pacheco, Francisco; Solar, Antonieta; Crovari, Fernando J.; Jarufe, Nicolas P.
    Arteriovenous malformation (AVM) of the pancreas (AVMP) is uncommon and generally asymptomatic; therefore, few cases have so far been reported. The symptoms of AVMP include gastrointestinal bleeding, pain, and portal hypertension. Definitive diagnosis is confirmed by angiographic study, and surgery is the only effective treatment. We report a case of AVMP confirmed by computed tomography, magnetic resonance imaging, and angiographic study of the abdomen, in a patient who presented to us with epigastric pain. He underwent a pancreaticoduodenectomy, following which his symptoms resolved.

    Cervical metastases of glucagonoma in a patient with multiple endocrine neoplasia type 1: Report of a case
    (2008) Butte, Jean M.; Montero, Pablo H.; Solar, Antonieta; Torres, Javiera; Olmos, Pablo R.; Goni, Ignacio; Quintana, Juan C.; Martinez, Jorge; Llanos, Osvaldo
    Multiple endocrine neoplasia type 1 (MEN 1) is a syndrome characterized by tumors of the parathyroid glands, pancreatic islet cells, duodenum, and pituitary gland. We report a case of cervical metastases of glucagonoma with MEN 1. The patient was a 34-year-old woman admitted to our hospital with epigastric pain. Her medical history included two resections of prolactinoma and two upper GI hemorrhages secondary to duodenal ulcers. Computed tomography (CT) showed two hypervascular lesions in the tail of the pancreas and cervical ultrasound showed multiple hypoechogenic ovoid images in the neck. A cervical CT scan confirmed two 15-mm lymph nodes in the left cervical region and 111In-DOTATOC imaging showed focal abnormal somatostatin expression in the pancreatic tail and the cervical nodes. The patient had asymptomatic hypoglycemic episodes, with blood sugar levels as low as 30 mg/dl, which raised our suspicion of MEN 1 associated with pancreatic insulinoma. Thus, we performed a distal pancreatectomy with bilateral cervical dissection and parathyroid gland resection. Histopathological examination revealed 12 pancreatic tumors as well as metastases in four cervical lymph nodes. The resected parathyroid glands had normal structure, suggesting parathyroid hyperplasia. A follow-up CT scan, 18 months after surgery, showed new tumors in the head of the pancreas and in the duodenal wall. A pancreatoduodenectomy was performed and histopathological examination revealed nine nonfunctioning endocrine tumors in the pancreas, one tumor in the duodenal wall, and metastases in two peripancreatic lymph nodes. The patient recovered well and remains asymptomatic.

    ' IHPBA-APHPBA clinical practice guidelines': international Delphi consensus recommendations for gallbladder cancer
    (2024) Palepu, Jagannath; Endo, Itaru; Chaudhari, Vikram Anil; Murthy, G. V.

    Background: The Delphi consensus study was carried out under the auspices of the International and Asia-Pacific Hepato-Pancreato-Biliary Associations (IHPBA-APHPBA) to develop practice guidelines for management of gallbladder cancer (GBC) globally. Method: GBC experts from 17 countries, spanning 6 continents, participated in a hybrid four-round Delphi consensus development process. The methodology involved email, online consultations, and in-person discussions. Sixty eight clinical questions (CQs) covering various domains related to GBC, were administered to the experts. A consensus recommendation was accepted only when endorsed by more than 75% of the participating experts. Results: Out of the sixty experts invited initially to participate in the consensus process 45 (75%) responded to the invitation. The consensus was achieved in 92.6% (63/68) of the CQs. Consensus covers epidemiological aspects of GBC, early, incidental and advanced GBC management, definitions for radical GBC resections, the extent of liver resection, lymph node dissection, and definitions of borderline resectable and locally advanced GBC. Conclusions: This is the first international Delphi consensus on GBC. These recommendations provide uniform terminology and practical clinical guidelines on the current management of GBC. Unresolved contentious issues like borderline resectable/locally advanced GBC need to be addressed by future clinical studies.

    Pulse Contour Analysis and Transesophageal Echocardiography: A Comparison of Measurements of Cardiac Output During Laparoscopic Colon Surgery
    (LIPPINCOTT WILLIAMS & WILKINS, 2009) Concha, Mario R.; Mertz, Veronica F.; Cortinez, Luis I.; Gonzalez, Katya A.; Butte, Jean M.
    BACKGROUND: Pulse wave analysis (PWA) allows cardiac output (CO) measurement after calibration by transpulmonary thermodilution. A PWA system that does not require previous calibration, the FloTrac/Vigileo (FTV), has been recently developed. We compared determinations of CO made with the FTV to simultaneous measurements using transesophageal echocardiography (TEE).

    Regional Differences in Gallbladder Cancer Pathogenesis: Insights from a Comparison of Cell Cycle-Regulatory, PI3K, and Pro-Angiogenic Protein Expression
    (2013) Butte, Jean M.; Torres, Javiera; Veras, Emanuela F.; Matsuo, Kenichi; Goenen, Mithat; D'Angelica, Michael I.; Waugh, Enrique; Meneses, Manuel; Inayama, Yoshiyaki; Fong, Yuman; DeMatteo, Ronald P.; De La Fuente, Hernan; Endo, Itaru; Klimstra, David S.; Jarnagin, William R.
    The variable incidence of gallbladder cancer (GBCA) suggests regional pathogenetic differences. This study compares cell cycle-regulatory, angiogenesis-related, and PI3K pathway protein expression in GBCAs from three continents.

    Sleeve gastrectomy as obesity after orthotopic treatment for severe liver transplantation
    (2007) Butte, Jean M.; Devaud, Nicolas; Jarufe, Nicolas P.; Boza, Camilo; Perez, Gustavo; Torres, Javiera; Perez-Ayuso, Rosa M.; Arrese, Marco; Martinez, Jorge
    Obesity is highly prevalent in both liver transplant candidates and recipients, and can have a significant impact on perioperative morbidity and mortality and the overall cost of transplantation. Herein, we describe an obese patient who was managed sequentially with an intragastric balloon in the pre-transplant setting and a gastric sleeve following transplantation, with good long-term results. Sleeve gastrectomy is a non-malabsorptive bariatric procedure with potential benefit for liver transplant patients due to its lack of influence on the absorption of immunosuppressive agents.

    The Volume of Lactated Ringer's Solution Required to Maintain Preload and Cardiac Index During Open and Laparoscopic Surgery
    (LIPPINCOTT WILLIAMS & WILKINS, 2009) Concha, Mario R.; Mertz, Veronica F.; Cortinez, Luis I.; Gonzalez, Katya A.; Butte, Jean M.; Lopez, Francisco; Pinedo, George; Zuniga, Alvaro
    BACKGROUND: Recent studies have emphasized the importance of perioperative fluid restriction. However, fluid restriction regimens may increase the likelihood of insufficient perioperative fluid administration or may result in excess intravascular crystalloid replacement. We postulate that the use of transesophageal echocardiography may reduce the amount of crystalloid administered during open and laparoscopic colorectal surgery.
