TeleInGEstion Remote Video Capsule Endoscope.

We describe 2 cases in which video capsule endoscopy was performed remotely using TeleInGEstion Remote Video Capsule Endoscopy (TIGER VCE), given limited access to endoscopy during the COVID-19 pandemic. The patients ingested the CapsoCam capsule during a televisit, and the video was subsequently reviewed remotely by the physician. TIGER VCE was used to diagnose a benign etiology of melena and used to confirm a diagnosis of Crohn's disease before the initiation of biologic therapy. These cases demonstrate the safety and efficacy of TIGER VCE. We feel that this technique may be considered as a standard ingestion technique in the future.

Cardiac Standstill With Intracardiac Clot Formation.

This case describes and depicts cardiac standstill with thrombosed blood within the chambers of the heart. This was likely due to stasis of blood from a prolonged no-flow state. After viewing this ultrasound finding, the decision was made to halt resuscitative efforts in this case of a patient in cardiac arrest.

Endoscopic ultrasound-guided fine-needle aspiration and Trucut biopsy in thoracic lesions: when tissue is the issue.

BACKGROUND: Endoscopic ultrasound-guided fine-needle aspiration (EUS FNA) has a high accuracy in the evaluation of mediastinal lesions. The use of a core biopsy needle for EUS guided biopsy (EUS TCB) may further improve the yield of EUS. The aims of this study are to evaluate the safety of EUS TCB in thoracic lesions and to compare the diagnostic accuracy of TCB with FNA and FNA + TCB. METHODS: A single-center retrospective study. All patients underwent EUS-FNA and TCB. A cytopathologist was not present during the procedure. EUS FNA, TCB and FNA + TCB diagnostic accuracy were compared. RESULTS: A total of 48 patients were included. The lesions sampled included 41 lymph nodes (six aorto-pulmonary window, 32 subcarinal, two right paratracheal, one paraesophageal ATS station 8), five lung masses, and two esophageal masses. Twenty-nine patients had malignant disease and 19 had benign disorders. The overall diagnostic accuracy of FNA, TCB and FNA + TCB was 79%, 79% and 98% respectively (p = 0.007). TCB changed the diagnosis in nine cases missed by FNA. EUS TCB was better than FNA for benign diseases (89% vs. 63%, p = 0.04). All eight patients with a prior failed biopsy had a correct diagnosis established by EUS. No patient required mediastinoscopy or thoracoscopy after EUS. CONCLUSION: The combination of TCB and FNA is superior to FNA alone. EUS-guided TCB should be considered in patients with benign disorders of the mediastinum when other modalities fail to yield a diagnosis.

Evaluation of fine needle aspiration vs. fine needle capillary sampling on specimen quality and diagnostic accuracy in endoscopic ultrasound-guided biopsy.

OBJECTIVE: To compare percutaneous and endoscopic ultrasound (EUS)-guided biopsy techniques. STUDY DESIGN: From July 2005 to February 2006, all patients referred for EUS-guided fine needle aspiration (FNA) were considered. If inclusion criteria were met, the first 2 biopsy passes were performed without suction (fine needle capillary [FNC] sampling). Two additional passes were performed using the same needle with 10 mL of applied suction (FNA). A single blinded pathologist later retrospectively evaluated each set of slides. Fifty-three patients met inclusion criteria. The study group comprised pancreatic masses (23), lymph nodes (26), subepithelial masses (3) and liver lesion (1). There were 38 malignant and 15 benign lesions. RESULTS: No statistically significant differences were found with the scoring systems considered in the study. In the subgroups of patients with pancreatic masses, lymph nodes, benign disease and malignant disease, no statistically significant outcomes were noted. CONCLUSIONS: No difference exists between quality and diagnostic accuracy of specimens obtained from EUS-guided tissue acquisition via FNC and FNA. The decision to use FNC or FNA should be left to the discretion of the individual endosonographer.

Advantage of EUS Trucut biopsy combined with fine-needle aspiration without immediate on-site cytopathologic examination.

BACKGROUND: Endoscopic ultrasonographically guided fine-needle aspiration (EUS-FNA) is a safe and accurate method for obtaining diagnostic material from lesions within and immediately adjacent to the upper GI tract. OBJECTIVE: To determine whether EUS Trucut biopsy (EUS-TCB) (Quickcore, Wilson-Cook, Winstom Salem, NC) can increase the accuracy of EUS-guided tissue sampling when combined with FNA when no cytopathologist is present. DESIGN: Retrospective case review. SETTING: University-based referral practice. PATIENTS: All patients who had lesions that were accessible through the esophagus or stomach and that were greater than 20 mm and amenable to Trucut biopsy were included. INTERVENTIONS: A total of 41 patients underwent both EUS-FNA and TCB with a separate pathologist evaluating each specimen. MAIN OUTCOME MEASUREMENTS: The diagnostic performance of FNA, TCB, and its combination were compared. RESULTS: The overall accuracy in our series was as follows: FNA, 76%; TCB, 76% (P not significant); and combination of FNA and TCB, 95% (P = .007). In the 26 patients with malignant diagnoses, the accuracy of combination was 100% versus 77% for FNA (P = .03). The median number of passes with the FNA and TCB was 4.4 (range 2-8) and 2.8 (range 2-5), respectively. One patient in the series had fever and chest pain after EUS biopsy. LIMITATIONS: Retrospective study. CONCLUSION: In our series EUS-TCB accuracy was equal to FNA when no on-site cytopathologist is present. TCB was helpful in the diagnosis of pancreatic masses, gastric submucosal lesions, lymphoma, and necrotic tumors. A 100% accuracy of FNA + TCB was seen in patients with malignant diseases and in patients who had failed or been refused biopsy by other modalities in the past. More data are needed before the exact role of TCB in the absence of on-site cytopathology can be accurately defined.

Contraindications to capsule endoscopy: do any still exist?

In patients requiring WCE most contraindications are relative and the procedure can be performed safely in almost all clinical settings. The only true remaining contraindications to capsule endoscopy are obstruction/pseudo-obstruction and pregnancy. Informed consent of the risks and benefits, including NNE, should be discussed with all patients undergoing WCE examination.

Pulmonary manifestations of inflammatory bowel disease.

Extraintestinal manifestations of both Crohn's disease and ulcerative colitis (UC) have been well described, although pulmonary findings are often overlooked. We summarize the experience of more than 400 cases of pulmonary manifestations of inflammatory bowel disease (IBD). These manifestations will be categorized by disease mechanism into drug-induced disease, anatomic disease, over-lap syndromes, autoimmune disease, physiologic consequences of IBD, pulmonary function test abnormalities, and nonspecific lung disease. We intend to provide the clinician with a practical working update on the spectrum of pulmonary dysfunction associated with IBD.
