RESUMEN
Background and study aims: Endoscopy plays an essential role in managing patients with ulcerative colitis (UC), as it allows us to visualize and assess the severity of the disease. As such assessments are not always objective, different scores have been devised to standardize the findings. The main aim of this study was to assess the interobserver variability between the Mayo Endoscopy Score (MES), Ulcerative Colitis Endoscopy Index of Severity (UCEIS) and Ulcerative Colitis Colonoscopy Index of Severity (UCCIS) analyzing the severity of the endoscopic lesions in patients with ulcerative colitis. Patients and methods: This was a single-cohort observational study in which a colonoscopy was carried out on patients with UC, as normal clinical practice, and a video was recorded. The results from the video were classified according to the MES, UCEIS and UCCIS by three endoscopic specialists independently, and they were compared to each other. The Mayo Endoscopy Score (MES) was used to assess the clinical situation of the patient. The therapeutic impact was analyzed after colonoscopy was carried out. Results: Sixty-seven patients were included in the study. The average age was 51 (SDâ±â16.7) and the average MES was 3.07 (SDâ±â2.54). The weighted Kappa index between endoscopists A and B for the MES was 0.8; between A and C 0.52; and between B and C 0.49.âThe intraclass correlation coefficient for UCEIS was 0.92 among the three endoscopists (CI 95â%: 0.83-0.96) and 0.96 for UCCIS among the three endoscopists (CI 95â% 0.94-0.97). A change in treatment for 34.3â% of the patients was implemented on seeing the results of the colonoscopy. Conclusions: There was an adequate, but not perfect, correlation between the different endoscopists for MES, UCEIS, UCCIS.âThis was higher with the last two scores. Thus, there is still some subjectivity to be minimized through special training, on assessing the seriousness of the endoscopic lesions in patients with UC.

INTRODUCTION: endoscopy plays an essential role in the management of patients with ulcerative colitis (UC), as it allows us to visualize and assess the severity of the disease. Different scores have been devised to standardize the findings because such assessments are not always objective. AIMS: the aim of this study was to assess the interobserver variability between the Index of Mayo Endoscopy (IME) and the Ulcerative Colitis Endoscopy Index of Severity (UCEIS), analyzing the severity of the endoscopic lesions in patients with UC. The secondary aim was to analyze if the cathartic preparation affected the degree of concordance amongst the endoscopists. MATERIAL AND METHODS: this was a single-cohort observational, comparative study in which a colonoscopy was performed in patients with UC, as the normal clinical practice. The results were classified according to the IME and the UCEIS by three endoscopic specialists. In order to assess the degree of interobserver correlation, the Kappa index for IME was used and the intraclass correlation coefficient was used for UCEIS. RESULTS: sixty-seven patients were included in the study. The average age was 51 (SD ± 16.7) and the average Mayo Clinic index was 3.07 (SD ± 2.54). The weighted Kappa index between endoscopists A and B for the IME was 0.8, 0.52 between A and C and 0.49 between B and C. The intraclass correlation coefficient for UCEIS was 0.922 between the three endoscopists (95 % CI: 0.832-0.959). A better interobserver correlation was found when the cathartic preparation was ≥ 8 based on the Boston Scale. CONCLUSIONS: there was a higher correlation between the different endoscopists for the UCEIS than for the IME. Thus, this should be considered to be the best index to use in the clinical practice. A good cleansing preparation is important to improve the interobserver correlation.

Endoscopic ultrasound (EUS)-guided drainage of pancreatic collections has replaced surgery as the first line of treatment due its accuracy and safety profile. A higher success rate and fewer adverse events has been observed using fully covered metal stent for the drainage. However, complications of EUS-guided drainage can appear. We present a case of late migration of the stent.
RESUMEN
Endoscopic ultrasound (EUS)-guided drainage is now the treatment of choice in cases of pancreatic pseudocysts and walled-off necrosis, especially in the absence of luminal bulging and in patients with portal hypertension. Malignant refractory ascites usually heralds a poor prognosis and substantially impairs the quality of life of patients because of the symptoms experienced and the need for repeated paracentesis. EUS-guided placement of lumen-apposing, fully covered, self-expandable metal stents (FCSEMS) has been reported for the drainage of malignant ascites. Herein, we present the results of EUS-guided placement of plastic pigtails stents for the drainage of refractory malignant ascites in three patients. The aim was to improve symptoms and minimize the possible drawbacks of large-caliber FCSEMS.âIn this preliminary experience, EUS-guided placement of plastic stents was feasible and avoided further paracentesis.
RESUMEN
BACKGROUND: Therapy of gastric varices (GV) is still challenging. Cyanoacrylate (CYA) injection is the recommended treatment for bleeding GV, but has a known adverse event rate, which could be reduced if EUS is used for guidance. Otherwise, EUS-guided coil application (ECA) may be an alternative. OBJECTIVES: To compare CYA and ECA embolization of feeding GV for feasibility, safety, and applicability. DESIGN: Retrospective analysis of a prospectively maintained database. SETTING: Multicenter study, tertiary referral centers. PATIENTS AND INTERVENTIONS: Thirty consecutive patients with localized GV who received either CYA injection or ECA were included with follow-up for 6 months after treatment. RESULTS: There were 11 patients in the coil group and 19 patients in the CYA group. The GV obliteration rate was 94.7% CYA versus 90.9% ECA; mean number of endoscopy sessions was 1.4 ± 0.1 (range 1-3). Adverse events occurred in 12 of 30 patients (40%) (CYA, 11/19 [57.9%]; ECA, 1/11 [9.1%]; P < .01); only 3 were symptomatic, and an additional 9 (CYA group) had glue embolism on a CT scan but was asymptomatic. No further adverse events occurred during follow-up. Six patients (20%) died unrelated to the procedures or bleeding. LIMITATIONS: Nonrandomized; EUS expertise necessary. CONCLUSIONS: EUS-guided therapy for GV by using CYA or ECA is effective in localized GV. ECA required fewer endoscopies and tended to have fewer adverse events compared with CYA injection. Larger comparative studies are needed to prove these data.

BACKGROUND: Bleeding from gastric varices can be challenging because of its high mortality and recurrent bleeding rates. Endoscopic therapy with tissue adhesives can control acute hemorrhage, but recurrent bleeding could appear if obliteration is not achieved, and endoscopic vision could be troublesome in the case of massive hemorrhage. The glue injected could be responsible for embolic phenomena and local complications. EUS has proved useful in minimizing the risk of recurrent bleeding from gastric varices, accurately showing if they are obturated or not. The presence of perforating veins detected by EUS has been reported as a risk factor for recurrent bleeding from esophageal varices. OBJECTIVE: To assess the efficacy of EUS-guided cyanoacrylate injection in gastric varices at the entrance of the perforating veins to obtain variceal obturation. DESIGN: Open-basis case series study. SETTING: Tertiary care, academic medical center, Seville, Spain. PATIENTS: Five consecutive patients with gastric varices were enrolled from May 2005 through May 2006. INTERVENTIONS: We injected cyanoacrylate-lipiodol in gastric varices with 22-gauge needles by EUS guidance. MAIN OUTCOME MEASUREMENTS: To analyze the obliteration of gastric varices, the recurrent bleeding rate, and safety of EUS-guided cyanoacrylate-lipiodol injection. RESULTS: EUS-guided injection of the perforating veins by using cyanoacrylate-lipiodol was successful in eradicating gastric varices in the 5 patients treated, without recurrent bleeding or other complications during the study follow-up. LIMITATION: This is a single-center nonrandomized study. CONCLUSIONS: EUS-guided injection of cyanoacrylate at the level of the perforating veins in the treatment of gastric varices seems to be a safe, efficient, and accurate approach. Further controlled studies are warranted.

BACKGROUND AND AIMS: There are several treatment options for gastroesophageal variceal hemorrhage. In severe cases, bleeding persists and is associated with a dismal outcome. The coagulation disorders might be correlated with risk of bleeding in patients with portal hypertension. The administration of activated recombinant factor VII corrects prothrombin time transiently in nonbleeding patients with cirrhosis as well as in bleeding ones. The aim of this study was to assess the hemostatic efficacy of activated recombinant factor VII in bleeding esophageal varices. METHODS: Between May 2001 and September 2002, 112 patients with cirrhosis and an episode of acute esophageal variceal bleeding were admitted. On an open basis with a single intravenous dose of 4.8 mg of recombinant factor VII, we treated 8 patients experiencing severe and active hemorrhage from esophageal varices unresponsive to pharmacologic therapy, endoscopic therapy, or balloon tamponade. RESULTS: Eight (7%) of 112 patients met entry criteria. Hemostasis was achieved in all the cases after recombinant activated factor VII therapy. Rebleeding and mortality rates were 25% and 50% (2 and 4 patients), respectively. CONCLUSIONS: In our experience, recombinant activated factor VII achieves hemostasis in bleeding esophageal varices unresponsive to standard treatment.
