RESUMEN
OBJECTIVES: Pancreatic pseudocysts (PPC) are fluid collections with a well-defined wall that persist for more than 4 weeks inside or around the pancreas as a result of pancreatic inflammation and/or a ductal lesion. PPC have been successfully treated with endoscopic ultrasound (EUS)-guided drainage using different stents. This study aimed to evaluate the safety and efficacy of EUS-guided drainage of PPC using double-pigtail plastic stents in a tertiary hospital. METHODS: Patients with PPC referred for EUS-guided drainage between May 2015 and December 2019 were included in this case series. The primary endpoint was to evaluate the efficacy (clinical success) and safety (adverse events and mortality) of EUS-guided drainage of PPC. Secondary endpoints included technical success and pseudocyst recurrence. RESULTS: Eleven patients (mean age, 44.5±18.98 years) were included in this study. The etiologies for PPC were acute biliary pancreatitis, chronic alcoholic pancreatitis, and blunt abdominal trauma. The mean pseudocyst size was 9.4±2.69 cm. The clinical success rate was 91% (10/11). Adverse events occurred in three of 11 patients (27%). There were no cases of mortality. The technical success rate was 100%. Pseudocyst recurrence was identified in one of 11 patients (9%) at 12 weeks after successful clinical drainage and complete pseudocyst resolution. CONCLUSION: EUS-guided transmural drainage of PPC using double-pigtail plastic stents is safe and effective with high technical and clinical success rates.

Background - Upper gastrointestinal bleeding implies significant clinical and economic repercussions. The correct establishment of the latest therapies for the upper gastrointestinal bleeding is associated with reduced in-hospital mortality. The use of clinical pathways for the upper gastrointestinal bleeding is associated with shorter hospital stay and lower hospital costs. Objective - The primary objective is the development of a clinical care pathway for the management of patients with upper gastrointestinal bleeding, to be used in tertiary hospital. Methods - It was conducted an extensive literature review on the management of upper gastrointestinal bleeding, contained in the primary and secondary information sources. Results - The result is a clinical care pathway for the upper gastrointestinal bleeding in patients with evidence of recent bleeding, diagnosed by melena or hematemesis in the last 12 hours, who are admitted in the emergency rooms and intensive care units of tertiary hospitals. In this compact and understandable pathway, it is well demonstrated the management since the admission, with definition of the inclusion and exclusion criteria, passing through the initial clinical treatment, posterior guidance for endoscopic therapy, and referral to rescue therapies in cases of persistent or rebleeding. It was also included the care that must be taken before hospital discharge for all patients who recover from an episode of bleeding. Conclusion - The introduction of a clinical care pathway for patients with upper gastrointestinal bleeding may contribute to standardization of medical practices, decrease in waiting time for medications and services, length of hospital stay and costs.

AIM: To evaluate the efficacy and safety of undiluted N-butyl-2 cyanoacrylate plus methacryloxysulfolane (NBCM) as a prophylactic treatment for gastric varices (GV) bleeding. METHODS: This prospective study was conducted at a single tertiary-care teaching hospital between October 2009 and March 2013. Patients with portal hypertension (PH) and GV, with no active gastrointestinal bleeding, were enrolled in primary prophylactic treatment with NBCM injection without lipiodol dilution. Initial diagnosis of GV was based on endoscopy and confirmed with endosonography (EUS); the same procedure was used after treatment to confirm eradication of GV. After puncturing the GV with a regular injection needle, 1 mL of undiluted NBCM was injected intranasally into GV. The injection was repeated as necessary to achieve eradication or until a maximum total volume of 3 mL of NBCM had been injected. Patients were followed clinically and evaluated with endoscopy at 3, 6 and 12 mo. Later follow-ups were performed yearly. The main outcome measures were efficacy (GV eradication), safety (adverse events related to cyanoacrylate injection), recurrence, bleeding from GV and mortality related to GV treatment. RESULTS: A total of 20 patients (15 male) with PH and GV were enrolled in the study and treated with undiluted NBCM injection. Only 2 (10%) patients had no esophageal varices (EV); 18 (90%) patients were treated with endoscopic band ligation to eradicate EV before inclusion in the study. The patients were followed clinically and endoscopically for a median of 31 mo (range: 6-40 mo). Eradication of GV was observed in all patients (13 patients were treated with 1 session and 7 patients with 2 sessions), with a maximum injected volume of 2 mL NBCM. One patient had GV recurrence, confirmed by EUS, at 6-mo follow-up, and another had late recurrence with GV bleeding after 35 mo of follow-up; overall, GV recurrence was observed in 2 patients (10%), after 6 and 35 mo of follow-up, and GV bleeding rate was 5% (1 patient). Mild epigastric pain was reported by 3 patients (15%). No mortality or major complications, including embolism, or damage to equipment were observed. CONCLUSION: Endoscopic injection with NBCM, without lipiodol, may be a safe and effective treatment for primary prophylaxis of gastric variceal bleeding.
RESUMEN
OBJECTIVE: To investigate the impact of transgastric peritoneal access on plasma biomarkers of acute inflammatory response in comparison to laparoscopy. METHODS: This was a prospective and comparative study in a porcine model. Transgastric peritoneal access performed by natural orifice transluminal endoscopic surgery was compared with laparoscopy. Laparotomy and sham groups were used as positive and negative controls, respectively. Thirty-four pigs were assigned to receive transgastric natural orifice transluminal endoscopic surgery (nâ=â12), laparoscopy (nâ=â8), laparotomy (nâ=â8) or a sham procedure involving only anesthesia (nâ=â6). In the natural orifice transluminal endoscopic surgery group, peritoneoscopy was performed with a gastroscope via transgastric access. Blood samples were collected at baseline and 1, 3, 6, 9 and 24 h after the surgical procedure for measurement of interleukins 1ß, 6 and 10 and tumor necrosis factor-α. A complete blood count was performed, and C-reactive protein levels were measured at baseline and at 24 h. RESULTS: All surgical and endoscopic procedures were performed without major complications. Peritoneal cavity inventory showed no signs of peritonitis in any animal. Interleukin 1ß, interleukin 10 and tumor necrosis factor-α levels were below the threshold of detection. The mean level of interleukin 6 was statistically significantly higher in the laparotomy group than in the other groups (p<0.05), with no significant differences among the sham, laparoscopy and natural orifice transluminal endoscopic surgery groups (p>0.05). C-reactive protein analysis indicated significant increases in all groups, with no differences among the groups. Complete blood count analysis showed no differences among the groups. CONCLUSIONS: Based on the observed interleukin 6 patterns, the systemic inflammatory response resulting from transgastric peritoneal access by natural orifice transluminal endoscopic surgery is similar in intensity to the response that occurs after laparoscopy.

BACKGROUND: One of the main concerns of natural orifice surgery is the local and systemic impact on physiology. Few studies have compared natural orifice transluminal endoscopic surgery (NOTES) with other surgical modalities. Most studies are based on systemic variables such as postoperative serum cytokines, with conflicting results. Surgical trauma induces an early inflammatory response, release of cytokines, and local leukocyte activation and oxidative burst. Major surgical trauma is related to impairment of phagocytic function and an increase in production of active oxygen species by phagocytes. The aim of this study was to evaluate the impact of transgastric peritoneoscopy on peritoneal innate immune response compared with laparoscopy and laparotomy in swine. METHODS: Thirty-four male Sus scrofa domesticus swine were assigned to four groups: transgastric peritoneoscopy (13), laparoscopy (7), laparotomy (7), and sham procedure (7). Twenty-four hours after the procedure, peritoneal fluid cells were harvested by peritoneal washing after necropsy. Flow cytometry analysis of labeled S. aureus and E. coli phagocytosis by peritoneal neutrophils and macrophages was blindly performed. Oxidative burst activity measured by H(2)O(2) production under different challenges was also evaluated. RESULTS: Total operative time varied between all groups. The transgastric, laparoscopy, and laparotomy groups required 56, 17.2, and 40.3 min of mean operative time, respectively (p < 0.05). Even though the mean percentage and intensity of phagocytosis by peritoneal phagocytes were higher in the sham, transgastric, and laparoscopy groups, there was no significant difference between these groups and laparotomy. Macrophage production of H(2)O(2) has been shown to be similar among the transgastric, laparoscopy, and sham groups, and smaller than that in laparotomy (p < 0.05), either under basal conditions, while performing E. coli phagocytosis, or challenged by the presence of E. coli membrane lipopolysaccharide. CONCLUSION: Under the conditions of this study, transgastric peritoneoscopy has been shown to have minimal impact on peritoneal innate immune response.

CONTEXT: Band ligation (BL) is the most appropriate endoscopic treatment for acute bleeding or prophylaxis of esophageal variceal bleeding. Sclerotherapy with N-butyl-2-cyanoacrylate (CY) can be an alternative for patients with advanced liver disease. Bacteremia is an infrequent complication after BL while the bacteremia rate following treatment with CY for esophageal varices remains unknown. OBJECTIVES: To evaluate and compare the incidence of transient bacteremia between cirrhotic patients submitted to diagnostic endoscopy, CY and BL for treatment of esophageal varices. METHODS: A prospective study comprising the period from 2004 to 2007 was conducted at Hospital of Universidade Federal de São Paulo, UNIFESP, SP, Brazil. Cirrhotic patients with advanced liver disease (Child-Pugh B or C) were enrolled. The patients were divided into two groups according treatment: BL Group (patients undergoing band ligation, n = 20) and CY Group (patients receiving cyanoacrylate injection for esophageal variceal, n = 18). Cirrhotic patients with no esophageal varices or without indication for endoscopic treatment were recruited as control (diagnostic group n = 20). Bacteremia was evaluated by blood culture at baseline and 30 minutes after the procedure. RESULTS: After 137 scheduled endoscopic procedures, none of the 58 patients had fever or any sign suggestive of infection. All baseline cultures were negative. No positive cultures were observed after CY or in the control group - diagnostic endoscopy. Three (4.6 %) positive cultures were found out of the 65 sessions of band ligation (P = 0.187). Two of these samples were positive for coagulase-negative staphylococcus, which could be regarded as a contaminant. The isolated microorganism in the other case was Klebsiella oxytoca. The patient in this case presented no evidence of immunodeficiency except liver disease. CONCLUSIONS: There was no significant difference in bacteremia rate between these three groups. BL or CY injection for non-bleeding esophageal varices may be considered as low-risk procedures regarding bacteremia even when performed on patients with advanced liver disease.

CONTEXTO: A ligadura elástica é considerada o melhor tratamento endoscópico para o sangramento agudo por varizes esofágicas ou para profilaxia do sangramento varicoso, sendo a escleroterapia com N-2-butil-cianoacrilato uma alternativa para os pacientes com doença hepática avançada e distúrbio de coagulação. Bacteriemia é uma complicação rara associada à ligadura elástica, por outro lado, a incidência de bacteriemia relacionada com o uso de N-2-butil-cianoacrilato permanece desconhecida. OBJETIVOS: Avaliar e comparar a incidência de bacteriemia transitória entre os pacientes cirróticos submetidos a endoscopia digestiva alta diagnóstica, escleroterapia com N-2-butil-cianoacrilato ou ligadura elástica para tratamento das varizes esofágicas. MÉTODOS: Estudo prospectivo realizado entre 2004 e 2007 foi conduzido no Hospital da Universidade Federal de São Paulo, UNIFESP, Brasil. Cirróticos com doença hepática avançada (Child B ou C) foram incluídos. Os pacientes foram divididos em dois grupos de acordo com o tratamento: grupo ligadura elástica (pacientes submetidos a ligadura elástica, n = 20) e grupo N-2-butil-cianoacrilato (pacientes submetidos a injeção de N-2-butil-cianoacrilato, n = 18). Cirróticos sem varizes esofágicas ou com varizes esofágicas sem indicação de tratamento endoscópico foram recrutados como controles (grupo endoscopia diagnóstica, n = 20). Bacteriemia foi avaliada por hemocultura basal e 30 minutos após o procedimento. RESULTADOS: Dos 137 procedimentos endoscópicos realizados, nenhum dos 58 pacientes apresentou febre ou qualquer sinal sugestivo de infecção. Todas as hemoculturas de base foram negativas. Nenhuma cultura positiva foi observada após o uso de N-2-butil-cianoacrilato ou no grupo controle. Três (4,6 por cento) culturas positivas foram encontradas após as 65 sessões de ligadura elástica (P = 0,187). Duas dessas foram positivas para Staphylococcus coagulase-negativo, provavelmente relacionadas à contaminação. O microorganismo isolado no terceiro caso foi Klebsiella oxytoca. Nesse caso, o paciente apresentava a própria doença hepática como única situação relacionada à imunodeficiência. CONCLUSÕES: Não houve diferença significante na incidência de bacteriemia entre os três grupos de pacientes. Ligadura elástica ou injeção de N-2-butil-cianoacrilato para profilaxia do sangramento varicoso podem ser considerados procedimentos de baixo risco quanto ao surgimento de bacteriemia, mesmo em pacientes com doença hepática avançada.

OBJECTIVE: To determine whether Model for End-stage Liver Disease (MELD) Child-Turcotte-Pugh (CTP) classification, AST to platelet ratio index (APRI), and laboratory tests could predict the presence of esophageal varices (EV) or varices which need prophylactic therapy (medium or large size EV). METHODS: Three hundred patients with cirrhosis (193 men; mean age 53.1 years; majority with chronic C hepatitis) were prospectively analyzed. The presence of EV (any size and medium or large EV) was correlated with patients' characteristics (MELD, CTP classification, APRI, platelets count, and liver tests). RESULTS: One hundred and seventy-one patients (57%) had EV, of whom 35% (105) had varices which need prophylactic therapy (VPT). The distribution of EV according to CTP classification was as follows: A, 49%; B, 75.3% and C, 80%. Independent predictors of EV were: MELD higher than 8 (P=0.02); APRI higher than 1.64 (P=0.01); platelet count lower than 93,000/mm³ (P<0.01); aspartate aminotransferase higher than 1.34 × UNL (P=0.01), and total bilirubin higher than 1 mg/dl (P=0.04). MELD higher than 8 had the highest discriminative value for presence of EV (sensitivity=80.1%; specificity=51.2%; area under receiver operating characteristics=0.68). Factors independently associated with VPT were: thrombocytopenia (<92,000/mm³; P<0.01) and aspartate aminotransferase higher than 1.47 × UNL (P=0.03). Platelet count lower than 92,000/mm³ had sensitivity of 65.7%, specificity of 57.9%, and an area under receiver operating characteristics of 0.62 for the presence of VPT. CONCLUSION: High values on MELD are associated with EV and thrombocytopenia, with varices which need prophylactic therapy. As a result of their low sensitivity and specificity, it is suggested to maintain the recommendation of upper gastrointestinal endoscopy for all patients with cirhosis.

BACKGROUND: The results of variceal band ligation (VBL) in patients with advanced liver disease are unknown. Cyanoacrylate injection (CI) might have a better outcome than VBL in the treatment of esophageal varices (EV) in these patients. AIM: To compare VBL and CI in the treatment of EV in patients with advanced liver disease. PATIENTS AND METHODS: Thirty-eight patients with medium or large EV and Child-Pugh index of at least eight were randomized into two groups: VBL (n=20) and CI (n=18). The patients were followed-up for at least 6 months after the end of treatment. Main outcomes were eradication, bleeding, mortality, complication, and recurrence rates. RESULTS: Variceal eradication rates were similar in the VBL and CI groups (90 vs. 72%, P=0.39). Mean number of sessions until eradication was 3.17 and 3, respectively. Bleeding episodes until eradication were equally observed in both groups (P=0.17). Mortality (55 vs. 56%, P=0.52) and major complication rates (5 and 17%, P=0.32) were similar. Chest pain with dysphagia was more frequent in the CI group (55.6 vs. 10%, P=0.004). A higher risk of variceal recurrence was observed in the CI group (33 vs. 57%, P=0.04). CONCLUSION: No significant differences between the VBL and CI groups were observed in the treatment of EV in patients with advanced liver disease regarding mortality, variceal eradication, and major complications rates. However, minor complications and variceal recurrence were significantly more common in the CI group. In addition, there was a clear trend toward more bleeding episodes in patients included in the CI group.

BACKGROUND: Patients with liver cirrhosis frequently undergo diagnostic or therapeutic upper GI endoscopy (UGIE), and the liver disease might impair the metabolism of drugs usually administered for sedation. OBJECTIVE AND SETTING: To compare sedation with a combination of propofol plus fentanyl and midazolam plus fentanyl in cirrhotic outpatients undergoing UGIE. DESIGN: A prospective, randomized, controlled trial was conducted between February 2008 and February 2009. MAIN OUTCOMES MEASUREMENTS: Efficacy (proportion of complete procedures using the initial proposed sedation scheme), safety (occurrence of sedation-related complications), and recovery time were measured. RESULTS: Two hundred ten cirrhotic patients referred for UGIE were randomized to 2 groups: midazolam group (0.05 mg/kg plus fentanyl 50 µg intravenously) or propofol group (0.25 mg/kg plus fentanyl 50 µg intravenously). There were no differences between groups regarding age, sex, weight, etiology of cirrhosis, and Child-Pugh or American Society of Anesthesiologists classification. Sedation with propofol was more efficacious (100% vs 88.2%; P < .001) and had a shorter recovery time than sedation with midazolam (16.23 ± 6.84 minutes and 27.40 ± 17.19 minutes, respectively; P < .001). Complication rates were similar in both groups (14% vs 7.3%; P = .172). LIMITATIONS: Single-blind study; sample size. CONCLUSION: Both sedation schemes were safe in this setting. Sedation with propofol plus fentanyl was more efficacious with a shorter recovery time compared with midazolam plus fentanyl. Therefore, the former scheme is an alternative when sedating cirrhotic patients undergoing UGIE.

OBJECTIVE: To evaluate and to compare the diagnostic yield of ERCP brush cytology (ERCP) and EUS-FNA in patients with biliary strictures and evaluates the agreement between general pathologists (GP) and expert GI pathologists (GIP) in the final diagnosis of biliary strictures. METHODS: Patients with biliary strictures documented by ERCP were included. Brush cytology was performed and during EUS, only visible mass lesions or localized bile duct wall thickening were aspirated. The gold standard method for diagnosis was surgical histology and/or follow-up. Tissue sampling results were: malignant, suspicious, atypical, insufficiently or benign. Specimens were interpreted by GP and GIP, blinded for prior tests results. RESULTS: 46 patients were included. Final diagnosis was malignancy in 37 (26 pancreatic--11 biliary) and benign in 9 (8 chronic pancreatitis--1 common bile duct inflammatory stricture). Sensitivity and accuracy for ERCP brush cytology were 43.2% and 52.2% for GP and 51.4% and 58.7% for GIP. Sensitivity and accuracy for EUS-FNA were 52.8% and 58.5%, respectively for GP and 69.4% e 73.2% for GIP. In comparison, the combination of brush cytology and EUS-FNA demonstrated higher sensitivity and accuracy for both GP (64.9% and 69.6%, respectively) and GIP (83.8% and 84.8%, respectively) and improved agreement with final diagnosis for both (mostly for GIP). CONCLUSION: Both, ERCP brush cytology and EUS-FNA has a similar yield for the diagnosis of biliary strictures. However, the combination of these methods results in an improved diagnostic accuracy. In addition, GIP might be expected to interpret specimens with greater accuracy than GP.

BACKGROUND: Pancreatic cancer and cholangiocarcinoma are the main causes of malignant biliary stricture. Both types of cancers have dismal survival rates, and treatment has little or no effect on prolonging the patients lives. Prognostic definition at initial endoscopic retrograde cholangiopancreatography is important to choose the most suitable management. AIM: To analyse endoscopic brushing and bilirubinemia importance in determination of the survival of patients with malignant biliary stricture. METHODS: Patients with biliary strictures diagnosed during endoscopic retrograde cholangiopancreatography were submitted to double brushing cytology. Serum samples were taken from all patients for bilirubinemia assay. Patients were followed to determine the final diagnosis and survival rates. RESULTS: A total of 50 patients with biliary stricture underwent endoscopic retrograde cholangiopancreatography (40 ultimately found to have a final diagnosis of malignant disease). Hyperbilirubinemia or cytology brushing positive for malignancy was related to a shorter survival rate. CONCLUSION: This research data demonstrate the possibility of determining the prognosis of patients with malignant biliary stricture using endoscopic brushing results and bilirubinemia levels.

A maioria dos pacientes com câncer de esôfago é diagnosticada em estádio final da doença com alta morbimortalidade cirúrgica, e sobrevida em cinco anos muito baixa. O objetivo deste estudo foi comparar três métodos de paliação endoscópica para pacientes que não são candidatos a cirurgia. Num período de 36 meses, 42 pacientes com câncer de esôfago foram examinados. Após critérios de exclusão, 15 foram randonizados em três grupos (cinco em cada grupo): grupo I - prótese plástica esofágica, grupo II - injeção de álcool e grupo III - gastrostomia endoscópica. Avaliação nutricional foi feita antes e depois do tratamento.Índice de Karnofsky, escore de disfagia e avaliação subjetiva da qualidade de vida também foram estudados. Os pacientes foram seguidos até o óbito. Apesar do número pequeno, todos os três foram bons métodos de paliação. Os autores discutem os prós e contras de cada tratamento. Gastrostomia é provavelmente o melhor ( e mais barato) tratamento para manter o status nutricional em pacientes com fase final de neoplasia de esôfago. Apesar da prótese plástica e de injeção de álcool serem eficientes em aliviar a disfagia, os pacientes geralmente desenvolvem anorexia grave
