RESUMEN
Background and Objectives: In portal hypertension, gastric varix-associated bleeding is known to have higher transfusion requirements, uncontrolled bleeding, rebleeding, intensive care unit requirements, and death. EUS-guided coil insertion is now an acceptable modality for endoscopic management in cases of gastric varices. With this study, we discuss our large single-center experience in the use of EUS for coil and glue injection in gastric varices. We also look into adverse events associated with and possibilities of using this modality as both primary prophylaxis and a rescue therapy. Methods: The study was conducted in a tertiary care center in India. A total of 86 patients were included in the study. The indication for EUS-guided coil and glue was divided into 3 clinical situations, namely, rebleed, rescue, and primary. The technical success and clinical success, that is, control of bleed in patients, were confirmed by absence of Doppler signal on EUS, endoscopic view, and stabilized hemoglobin with no need of blood product transfusion to maintain hemoglobin. Results: The mean Child-Turcotte-Pugh score and Model for End-Stage Liver Disease-Na score were 9.2 and 14.6, respectively. The mean size of the gastric varices was 18.9 mm. The mean number of coils used was 2.9, and the average quantity of glue required was 1.6 mL. The technical success was 100% across the patient group. Clinical success was seen in 90% of the patient group. Mean follow-up was seen for 175.2 days. Conclusions: EUS-guided coil and glue therapy has a role in different clinical settings, as primary therapy, rebleed, and rescue therapy. It has significant technical and clinical success. Its role in treatment algorithms needs to be further studied in prospective studies. It may offer a cost advantage in comparison to interventional radiology-led interventions.
RESUMEN
BACKGROUND AND STUDY AIMS: The role of endoscopic-ultrasound (EUS) guided fine-needle aspiration (FNA) in patients with lymphadenopathy in terms of diagnostic adequacy and safety in large population is not well defined. The aim of this study was to evaluate diagnostic adequacy and safety of EUS-FNA in patients with lymphadenopathy. PATIENTS AND METHODS: Retrospective study from October 2010 to September 2015 at tertiary care center in Delhi-NCR. We analyzed data from 1005 EUS- FNAs of lymph nodes. RESULTS: The study cohort comprised 1005 lymph nodes in 865 patients; 68â% were males, mean age was 50â±â14 years. Indications of FNA were to look for etiology of pyrexia of unknown origin or staging of malignancy mainly. FNA was taken from mediastinal nodes (nâ=â528, 52.5â%) and intra-abdominal nodes (nâ=â477, 47.5â%). Median size of nodes at long axis and short axis was 17 (12â-â25.7) and 10 (8â-â15) mm respectively. Adequate material by FNA was obtained in 92.8â% cases. The cytopathologic diagnosis were malignancy in 153 (15.2â%), granulomatous change in 452 (42 %), and reactive lymphadenopathy in 328 (35.6â%). There was statistically significant difference seen between groups with pathological and reactive lymph nodes regarding size at long and short axis, hypoechoic nature, well defined borders and presence of necrosis and calcification. Procedure-related adverse effects were encountered in 6 patients (0.8â%). Four patients had mild mucosal bleeding in chronic liver disease patients and two had mild hepatic encephalopathy related to sedation. CONCLUSION: EUS-FNA of lymph nodes has good diagnostic adequacy and safety.
RESUMEN
BACKGROUND: Fine-needle aspiration (FNA) of adrenals is needed in patients with pyrexia of unknown origin (PUO) and adrenal enlargement in absence of other diagnostic clues. Adrenals are easily accessible by endoscopic ultrasound (EUS) due to proximity; however, there is no systemic study available on FNA of adrenals in patients with PUO. The aim of this study was to evaluate the diagnostic yield and safety of EUS-FNA of enlarged adrenal in patients with PUO. METHODS: Data was analyzed from October 2010 to September 2016 at a single tertiary care center in northern India. EUS-FNA of enlarged adrenals was done in 52 patients for the etiological diagnosis of PUO in whom a definitive diagnosis could not be made with other means. RESULTS: The mean age was 48±14 years; 36 were males and 16 were females. EUS-FNA was done from the left adrenal in 50 patients and from the right sample in 2 patients. A technical success was achieved in 100% cases. The 19-G needle was used in the majority (75%) to the presence of necrotic areas in adrenals; median numbers of passes were 2. The cytopathological diagnoses were tuberculosis (n = 36), histoplasmosis (n = 13), lymphoma (n = 2), and metastasis from undiagnosed neuroendocrine tumor of lung (n = 1). Thus, a diagnosis could be made in 52/52 (100%) patients. None of the patients had any procedure-related complications. CONCLUSIONS: EUS-FNA is a safe and effective method for evaluating etiology of PUO in patients with adrenal enlargement.

BACKGROUND AND AIM: There is paucity of data about endoscopic pancreatic sphincteroplasty (EPS) after endoscopic pancreatic sphincterotomy (EPST) in the treatment of chronic pancreatitis. The aim of this study was to establish the indications for EPS, complications related to it, and to examine its effectiveness in managing chronic pancreatitis after a year of follow-up. METHODS: We evaluated the safety and efficacy of pancreatic balloon dilation coupled with sphincterotomy for the treatment of chronic pancreatitis. The technical success rate of balloon dilation, stone clearance, frequency of pancreatic stenting, and procedure-related adverse events were recorded. RESULTS: Out of 580 patients who underwent pancreatic endotherapy between July 2014 and February 2016, 80 patients underwent EPS. The mean age of these 80 patients was 34â±â11 years, and 80â% (nâ=â64) were males. The common indications were removal of large radiolucent stones in 31 patients; unyielding radiopaque stones post extracorporeal shock wave lithotripsy (ESWL) in 20 patients, and pancreatic duct stricture combined with stones in 29 patients. EPS could be successfully completed in 98.75â% of patients. Complete ductal clearance in a single session was achieved in only 25 patients, while 26 patients required two sessions. There were two adverse events of pain requiring admission for more than 24 hours and one procedure related bleeding, all of which were managed conservatively. The patients had an average follow-up of 8 months (6â-â12 months) and all the patients were pain free. CONCLUSIONS: Endoscopic pancreatic sphincteroplasty is a relatively safe procedure with a low incidence of complications and a high rate of treatment success.
RESUMEN
BACKGROUND AND STUDY AIM: Different types of endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) techniques are used in clinical practice; the best method in terms of outcome has not been determined. The aim of the study was to compare the diagnostic adequacy of aspirated material, and the cytopathological and EUS morphological features between capillary action, suction, and no-suction FNA methods. PATIENTS AND METHODS: This was a prospective, single-blinded, randomized study conducted at a tertiary care hospital. Patients were randomized to the three groups: capillary action, suction, and no suction. A total of 300 patients were included, with 100 patients in each arm. RESULTS: A total of 300 patients (195 males) underwent EUS-FNA of 235 lymph nodes and 65 pancreatic masses (distribution not statistically different between the groups). The mean age was 52â±â14 years. A 22 gauge needle was used in the majority (93â%) of procedures. There was no statistical difference between the three groups regarding lymph node size at the largest axis and ratio, type of needle, echo features, echogenicity, calcification, necrosis, shape, borders (lymph nodes), number of passes, and cellularity. Diagnostic adequacy of the specimen was 91â%, 91â%, and 94â% in the capillary, suction, and no suction groups, respectively ( P â=â0.67). Significantly more slides and blood clots were generated by the suction method compared with the other methods. CONCLUSION: The capillary action, suction, and no suction methods of EUS-FNA are similar in terms of diagnostic adequacy of the specimen. The suction method has the disadvantages of causing more bleeding and generating more slides.
RESUMEN
BACKGROUND AND AIMS: Endoscopic ultrasound (EUS) guided drainage of symptomatic pancreatic walled-off necrosis (WON) followed by fully covered self-expanding metal stent (FCSEMS) placement offers several advantages such as higher technical success rate and the option of necrosectomy. The aim of this study was to evaluate the safety and efficacy of EUS guided drainage of patients with WON by using FCSEMS and intracavitary lavage with a solution containing hydrogen peroxide and adopting a step-up approach. METHODS: A prospective open label study was carried out at a single tertiary care center between January 2014 and January 2016. Patients with symptomatic WON who underwent EUS guided drainage followed by FCSEMS placement were included. Primary end points were complete drainage with improvement in symptoms or major adverse events. Secondary end points were minor adverse events related to the procedures. RESULTS: A total of 64 patients (mean age 36 years; 52 males) were included. Technical success was achieved in 100â% of patients and clinical success was achieved in 90.6â%. Complete drainage was achieved with FCSEMS alone in 18 (28.1â%), FCSEMS with necrosectomy using lavage in 40 (62.5â%), FCSEMS with percutaneous drainage (PCD) in 5 (7.8â%), and 1 (1.6â%) patient required salvage surgery. The major adverse event was life threatening bleeding in 3 (4.7â%) patients. Minor adverse events were non-life threatening bleeding in 2 (3.1â%) patients and stent migration in 3 (4.7â%) patients. CONCLUSION: EUS guided WON drainage with FCSEMS followed by necrosectomy with lavage using a solution containing hydrogen peroxide as a step-up approach is a minimally invasive and effective method with a high technical and clinical success rate. Patients with solid debris >â40â% need aggressive management.
