Background/Aims: Ineffective esophageal motility (IEM) is the most frequently encountered esophageal manometric abnormality. Nonobstructive dysphagia is frequently associated with severe esophageal peristaltic dysfunction. This study aims to evaluate the presenting symptoms and association between dysphagia and specific manometric findings in patients with IEM. Methods: We retrospectively reviewed 228 IEM patients diagnosed on high-resolution manometry at an academic institution (2010-2013). We collected data regarding the main presenting symptoms and manometric findings: bolus transit, distal esophageal pressure amplitude, and lower esophageal sphincter (LES) resting and relaxation pressure. Results: Dysphagia was the main presenting symptom (25%) in IEM patients. Bolus transit was incomplete in either liquid or viscous swallows (30%) and incomplete in both liquid and viscous swallows (59%) in IEM patients. The LES resting pressure and LES relaxation pressure were elevated (9% and 36%, respectively) in IEM patients. There was no significant difference between dysphagia and either poorly relaxing LES (P = 0.725) or defective bolus transit (DBT) to liquid and viscous swallows (P = 0.372) compared to the rest of the IEM patients. However, there was a significant association between dysphagia and the combination of poorly relaxing LES and DBT in liquid and viscous swallows (P = 0.006). Subgroup analysis comparing dysphagia with heartburn/regurgitation demonstrated a similar significant association between dysphagia and the combination of poorly relaxing LES and DBT during viscous and liquid swallows (P = 0.016). Conclusions Dysphagia is a variable symptom associated with complex esophageal motility abnormalities. IEM patients with a combination of poorly relaxing LES and DBT are more likely to have dysphagia.

Esophageal varices develop in almost half of the patients with cirrhosis, and variceal hemorrhage constitutes an ominous sign with an increased risk of mortality. Variceal banding is considered an effective and mostly safe measure for primary and secondary prophylaxis. Although adverse events related to banding including dysphagia, stricture formation, bleeding, and ligation-induced ulcers have been described, complete esophageal obstruction is rare, with only 10 reported cases in the literature. Among those cases, 6 were managed conservatively; 1 patient had esophageal intraluminal dissection from an attempt to remove the bands using biopsy forceps but ultimately recovered with conservative management. Three patients developed strictures following removal of the bands, requiring repeated sessions of dilation therapy. We report on a patient who developed absolute dysphagia and complete esophageal obstruction after variceal banding. We successfully used the endoloop cutter hook to release the bands intact and restore luminal integrity.

There is paucity in the literature on the use of endoscopic ultrasound (EUS) for evaluating the thyroid gland. We report the first case of primary papillary thyroid cancer diagnosed by using EUS and fine needle aspiration (FNA). A 66-year-old man underwent EUS for the evaluation of mediastinal lymphadenopathy. FNA of the lymph nodes showed benign findings. A hypoechoic mass was noted in the right lobe of the thyroid gland. Therefore, FNA was performed. The cytological results were consistent with primary papillary thyroid cancer.
