    ABSTRACT: Intra-abdominal lymphadenopathy is a common diagnostic challenge faced by clinicians. In the absence of palpable peripheral nodes, tissue is usually obtained from the abdominal nodes by image-guided biopsy or surgery. We speculate that EUS-guided FNA (EUS-FNA) avoids the morbidity of a laparotomy and might be equally effective. To evaluate the role of EUS-FNA in abdominal lymphadenopathy. Prospective study conducted over 42 months. Tertiary care center in New Delhi, India. Patients with abdominal lymphadenopathy in whom image-guided node biopsy failed were considered for EUS-FNA. A total of 3 passes were performed at each site. Slides were prepared per protocol and sent for cytopathologic evaluation. A total of 142 patients were enrolled, but only 130 (91.5%) underwent FNA. The mean lymph node size was 22 ± 3.2 mm; 71.8% of the nodes were hypoechoic (n = 102), and 28.1% were heterogeneous with an anechoic center (n = 40). In 120 patients (84.5%), the lymph nodes were intra-abdominal only, and in 22 patients (15.5%), they were both intra-abdominal and mediastinal in location. EUS-FNA was successful in establishing a diagnosis in 90.8% of these patients; 76.1% were found to have tuberculosis, 7.04% sarcoidosis, 6.33% Hodgkin's lymphoma, and 0.74% non-Hodgkin's lymphoma. In 8.4% patients, nodes were inaccessible because of their retropancreatic location. EUS-FNA is a safe, accurate, and minimally invasive modality for diagnosing the cause of abdominal lymphadenopathy. In highly endemic areas, tuberculosis is the most common cause.

    ABSTRACT: Endoscopic ultrasound guided pancreatic pseudocyst drainage (EUS-PPD) is increasingly being used for management of pancreatic pseudocysts. We evaluated the outcome and complications of EUS-PPD with modified combined technique by inserting both endoprosthesis and naso-cystic drain. Forty patients referred between August 2007 and January 2010 for EUS-PPD were prospectively studied. EUS-PPD was attempted for symptomatic pancreatic pseudocysts which were; (i) resistant to conservative treatment, (ii) in contact with the gastric or duodenal wall on EUS and (iii) having no bulge seen on endoscopy. Controlled radial expansion wire guided balloon dilation of the puncture tract was performed followed by insertion of a 10 French double pigtail stent and 7-Fr naso-biliary drain. The early and late outcome and complications of EUS-PPD were analyzed. Thirty-two patients had non-infected and eight had infected pseudocysts. EUS-PPD was technically successful in all. Pseudocysts resolved completely in 39 patients, while one with infected pseudocyst underwent surgical resection for bleeding in the cyst. Naso-cystic drain was removed in 39 patients after median duration of 13 days. Thereafter, the double pigtail stent was removed in all cases after median duration of 10 weeks. Pseudocyst recurred in one patient requiring a second session of EUS-PPD. All 32 patients without cystic infection were successfully treated by EUS-PPD. Seven out of eight patients (87%) with cystic infection were successfully treated by EUS-PPD. Endoscopic ultrasound guided pancreatic pseudocyst drainage with modified combined technique is safe and is associated with high success rate.
