Endoscopic Ultrasound-Guided Random Omental Fine Needle Aspiration: A Novel Technique for the Diagnosis of Peritoneal Carcinomatosis: Pradeep Kumar Siddappa, Neha Jain, Naveen K.

Background
/Aims: Diagnostic abdominal paracentesis has been described in literature to have variable sensitivity of 50%–75% for the detection of peritoneal carcinomatosis (PC). We believe that random needle aspirates from the omentum, even in the absence of obvious deposits by endoscopic ultrasound (EUS), could prove malignancy in patients with PC.
Methods
Consecutive patients who underwent EUS for diagnosis and staging of cancer and found to have ascites were included after obtaining informed consent. EUS-guided fine needle aspiration (EUS-FNA) from random sites in the omentum was performed through the transgastric route using a linear echoendoscope.
Results
Fifty-four patients underwent EUS during October 2015 to April 2017 for detection, staging, or FNA of a suspected malignant lesion. Ascites was seen in 17 patients and 15 patients who fulfilled the criteria were included. The procedure was successful in all patients. Cytology was suggestive of malignancy in 12 (80%) but not suggestive of malignancy in 3 (20%) patients. Three patients who tested negative had hyperbilirubinemia with biliary obstruction. Their ascitic fluid analysis result was also negative.
Conclusions
Random FNA of the omentum in patients with malignancy-related ascites is highly effective in the diagnosis of PC and could be employed during EUS evaluation of malignancies.

Omental Patching and Purse-String Endosuture Closure after Endoscopic Full-Thickness Resection in Patients with Gastric Gastrointestinal Stromal Tumors: Faisal Inayat, Aysha Aslam, Mathew D.

Abstract PDF

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, primarily arising from the stomach. With the widespread utilization of and technical advancements in endoscopy, gastric GISTs are being increasingly detected at an early stage, enabling complete endoscopic resection. Endoscopic full-thickness resection (EFTR) is an advanced technique that has been recognized as a treatment tool for neoplasms in the digestive tract in selected patients. Although a number of methods are available, closing large iatrogenic defects after EFTR can be a concern in clinical practice. If this potential problem is appropriately solved, patients with gastric GISTs would be suitable candidates for resection utilizing this technique. To our knowledge, this is the first study to propose omental patching and purse-string endosuture closure following EFTR as a feasible endoscopic option in patients with gastric GISTs.
