| 1 | Imatinib-induced fatal acute liver failure显示文摘Imatinib mesylate is a drug that has been approved for treatment of chronic myeloid leukemia (CML) in blast crisis, accelerated or chronic phase, and also for advanced gastrointestinal stromal tumors. Severe hepatic toxicity and three deaths from hepatic failure have been reported. We report the case of a 51-year-old woman who was admitted to our institution with severe acute hepatitis. She was diagnosed with CML and began treatment with imatinib mesylate at a dose of 400 mg/d. Five months after beginning treatment, she developed severe hepatitis associated with coagulopathy, and was admitted to our institution. She had been consuming acetaminophen 500-1000 mg/d after the onset of symptoms. She had a progressive increase in bilirubin level and a marked decrease of clotting factor Ⅴ. Five days after admission, grade Ⅱ encephalopathy developed and she was referred for liver transplantation. Her clinical condition progressively deteriorated, and 48 h after being referred for transplantation she suffered a cardiac arrest and died. This report adds concern about the possibility of imatinib-mesylate-induced hepatotoxicity and liver failure, particularly in the case of concomitant use with acetaminophen. Liver function tests should be carefully monitored during treatment and, with the appearance of any elevation of liver function tests, treatment should be discontinued. | Ezequiel Ridruejo Roberto Cacchione Alejandra G Villamil Sebastián Marciano Adrián C Gadano Oscar G Mandó | 2007 | World Journal of Gastroenterology2007，13，48： | 5 |
| 2 | Interplay between post-translational cyclooxygenase-2 modifications and the metabolic and proteomic profile in a colorectal cancer cohort显示文摘BACKGROUND Colorectal cancer(CRC) is the second most common cause of cancer death worldwide. It is broadly described that cyclooxygenase-2(COX-2) is mainly overexpressed in CRC but less is known regarding post-translational modifications of this enzyme that may regulate its activity, intracellular localization and stability. Since metabolic and proteomic profile analysis is essential for cancer prognosis and diagnosis, our hypothesis is that the analysis of correlations between these specific parameters and COX-2 state in tumors of a high number of CRC patients could be useful for the understanding of the basis of this cancer in humans.AIM To analyze COX-2 regulation in colorectal cancer and to perform a detailed analysis of their metabolic and proteomic profile.METHODS Biopsies from both healthy and pathological colorectal tissues were taken under informed consent from patients during standard colonoscopy procedure in the University Hospital of Bellvitge(Barcelona, Spain) and Germans Trias i Pujol University Hospital(Campus Can Ruti)(Barcelona, Spain). Western blot analysis was used to determine COX-2 levels. Deglycosylation assays were performed in both cells and tumor samples incubating each sample with peptide N-glycosidase F(PNGase F). Prostaglandin E2(PGE2) levels were determined using a specific ELISA. 1 H high resolution magic angle spinning(HRMAS) analysis was performed using a Bruker AVIII 500 MHz spectrometer and proteomic analysis was performed in a nano-liquid chromatography-tandem mass spectrometer(nano LC-MS/MS) using a QExactive HF orbitrap MS.RESULTS Our data show that COX-2 has a differential expression profile in tumor tissue of CRC patients vs the adjacent non-tumor area, which correspond to a glycosylated and less active state of the protein. This fact was associated to a lesser PGE2 production in tumors. These results were corroborated in vitro performing deglycosylation assays in HT29 cell line where COX-2 protein profile was modified after PNGase F incubation, showing higher PGE2 levels. Moreover,HRMAS analysis indicated that tumor tissue has altered metabolic features vs non-tumor counterparts, presenting increased levels of certain metabolites such as taurine and phosphocholine and lower levels of lactate. In proteomic experiments, we detected an enlarged number of proteins in tumors that are mainly implicated in basic biological functions like mitochondrial activity,DNA/RNA processing, vesicular trafficking, metabolism, cytoskeleton and splicing.CONCLUSION In our colorectal cancer cohort, tumor tissue presents a differential COX-2 expression pattern with lower enzymatic activity that can be related to an altered metabolic and proteomic profile. | Patricia Prieto Rafael I Jaén Daniel Calle María Gómez-Serrano Estefanía Nú?ez María Fernández-Velasco Paloma Martín-Sanz Sergio Alonso Jesús Vázquez Sebastián Cerdán Miguel ángel Peinado Lisardo Boscá | 2019 | World Journal of Gastroenterology2019，25，4： | 4 |
| 3 | Robotic transanal total mesorectal excision:Is the future now?显示文摘Total mesorectal excision(TME)is the standard surgical treatment for the curative radical resection of rectal cancers.Minimally invasive TME has been gaining ground favored by the continuous technological advancements.New procedures,such as transanal TME(TaTME),have been introduced to overcome some technical limitations,especially in low rectal tumors,obese patients,and/or narrow pelvis.The earliest TaTME reports showed promising results when compared with the conventional laparoscopic TME.However,recent publications raised concerns regarding the high rates of anastomotic leaks or local recurrences observed in national series.Robotic TaTME(R-TaTME)has been proposed as a novel technique incorporating the potential benefits of a perineal dissection together with precise control of the distal margins,and also offers all those advantages provided by the robotic technology in terms of improved precision and dexterity.Encouraging short-term results have been reported for R-TaTME,but further studies are needed to assess the real role of the new technique in the long-term oncological or functional outcomes.The present review aims to provide a general overview of R-TaTME by analyzing the body of the available literature,with a special focus on the potential benefits,harms,and future perspectives for this novel approach. | Juan Carlos Sebastián-Tomás Aleix Martínez-Pérez Elías Martínez-López Nicola de'Angelis Marcos Gómez Ruiz Eduardo García-Granero | 2021 | World Journal of Gastrointestinal Surgery2021，13，8： | 2 |
| 4 | Conservative management of perforated duodenal diverticulum: A case report and review of the literature显示文摘Duodenal diverticula are a relatively common condition. They are asymptomatic, unless they become complicated, with perforation being the rarest but most severe complication. Surgical treatment is the most frequently performed approach. We report the case of a patient with a perforated duodenal diverticulum, which was diagnosed early and treated conservatively with antibiotics and percutaneous drainage of secondary retroperitoneal abscesses. We suggest this method could be an acceptable option for the management of similar cases, provided that the patient is in good general condition and without septic signs. | David Martínez-Cecilia Alvaro Arjona Sánchez Manuel Gómez álvarez Eva Torres Tordera Antonio Luque Molina Victor Valentí Azcárate Javier Briceo Delgado Francisco Javier Padillo Pedro López-Cillero Sebastián Rufián Pea | 2008 | World Journal of Gastroenterology2008，14，12： | 2 |

| 12 | Laparoscopic approach in complicated diverticular disease显示文摘AIM: To analyze the results of laparoscopic colectomy in complicated diverticular disease.METHODS: This was a retrospective cohort study conducted at an academic teaching hospital. Data were collected from a database established earlier, which comprise of all patients who underwent laparoscopic colectomy for diverticular disease between 2000 and 2013. The series was divided into two groups that were compared: Patients with complicated disease(abscess, perforation, fistula, or stenosis)(G1) and patients undergoing surgery for recurrent diverticulitis(G2). Recurrent diverticulitis was defined as two or more episodes of diverticulitis regardless of patient age. Data regarding patient demographics, comorbidities, prior abdominal operations, history of acute diverticulitis, classification of acute diverticulitis at index admission and intra and postoperative variables were extracted. Univariate analysis was performed in both groups.RESULTS: Two hundred and sixty patients were included: 28%(72 patients) belonged to G1 and 72%(188 patients) to G2. The mean age was 57(27-89) years. The average number of episodes of diverticulitis before surgery was 2.1(r 0-10); 43 patients had no previous inflammatory pathology. There were significant differences between the two groups with respect to conversion rate and hospital stay(G1 18% vs G2 3.2%, P = 0.001; G1: 4.7 d vs G2 3.3 d, P < 0.001). The anastomotic dehiscence rate was 2.3%, with no statistical difference between the groups(G1 2.7% vs G2 2.1%, P = 0.5). There were no differences in demographic data(body mass index, American Society of Anesthesiology and previous abdominal surgery), operative time and intraoperative and postoperative complications between the groups. The mortality rate was 0.38%(1 patient), represented by a death secondary to septic shock in G2.CONCLUSION: The results support that the laparoscopic approach in any kind of complicated diverticular disease can be performed with low morbidity and acceptable conversion rates when compared with patients undergoing laparoscopic surgery for recurrent diverticulitis. | Nicolás A Rotholtz Alejandro G Canelas Maximiliano E Bun Mariano Laporte Emmanuel E Sadava Natalia Ferrentino Sebastián A Guckenheimer | 2016 | World Journal of Gastrointestinal Surgery2016，8，4： | 0 |
| 13 | Superior mesenteric artery syndrome in a patient with Charcot Marie Tooth disease显示文摘The extrinsic compression of the third part of the duodenum as it passes through the aorto-mesenteric angle is known as the superior mesenteric artery syndrome(SMAS).This syndrome is a rare mechanical cause of upper intestinal obstruction,with a reported incidence of between 0.2% and 0.78%.Clinical manifestations of SMAS may be chronic or acute;chronic symptoms include intermittent gastric pain,fullness and occasional episodes of postprandial vomiting,while acute symptoms include incoercible vomiting,oral intolerance,mainly epigastric abdominal distension and abdominal pain.Surgery is recommended only when initial conservative treatment fails.Here,we report what appears to be the third published case of SMAS associated with hereditary motor and sensory neuropathy or Charcot Marie Tooth disease. | óscar Dario Gómez Beltrán Amparo Valverde Martínez María del Carmen Pérez Manrique Joaquín Sánchez Rodríguez Enrique Lizárraga Febres Sebastián Ruf ián Pea | 2011 | World Journal of Gastrointestinal Surgery2011，3，12： | 0 |
