Esophageal papillomatosis is a very rare condition that is believed to have a benign clinical course. Recent reports underscore the potential development of a malignancy in association with squamous papillomatosis of the esophagus. A case of esophageal papillomatosis complicated by the development of esophageal invasive squamous cell carcinoma diagnosed after esophagectomy, despite multiple nondiagnostic endoscopic biopsies, is described. The patient also developed squamous cell carcinoma in the oral cavity and pyloric channel. The finding of extensive esophageal papillomatosis and unremitting dysphagia symptoms should prompt investigations into an underlying associated malignancy.
In a patient with a mid-common bile duct stone, the traction wires of a mechanical lithotriptor snapped, resulting in lithotriptor basket impaction. Simultaneous occurrence of these two potential complications of endoscopic stone extraction is very rarely reported. Extracorporeal shock wave lithotripsy failed to fragment the stone entrapped within the impacted basket. Endoscopic intracorporeal electrohydraulic shock wave lithotripsy successfully fragmented the stone under direct visualization through a cholangioscope. The entrapped stone within the basket could subsequently be pulled into the supra-ampullary bile duct for the final fragmentation with an extra-endoscopic mechanical lithotriptor cable. The present report is the first to describe a safe and effective use of endoscopic intracorporeal electrohydraulic shock wave lithotripsy followed by extra-endoscopic mechanical lithotripsy in the management of an impacted lithotriptor basket.
The diagnostic yield of EUS-FNA of the upper GI SELs with an onsite cytopathologic interpretation was 72.7%. Lesion size < 2 cm significantly reduces the diagnostic yield of EUS-FNA for the upper GI SELs.
Azathioprine and 6-mercaptopurine (6-MP) are effective in inflammatory bowel disease (IBD). However, between 10% and 29% of patients treated with these drugs are forced to stop therapy due to side effects. Pulmonary toxicity due to azathioprine/6-MP has been reported infrequently. We describe 3 patients who developed severe, noninfectious pulmonary toxicity within 1 month after the initiation of azathioprine or 6-MP for the treatment of IBD colitis (2 Crohn's disease and 1 ulcerative colitis). All patients presented with dyspnea, cough, and fever after initiation of azathioprine/6-MP. Evaluation for infectious etiologies, including bronchoscopy (3/3 patients) and open-lung biopsy (2/3 patients) was negative. Histopathologic examination of the lung biopsies revealed bronchiolitis obliterans organizing pneumonia in one, and usual interstitial pneumonitis in another patient. Cessation of purine analog therapy resulted in clinical improvement in all 3 cases. Azathioprine/6-MP-related pulmonary toxicity is a rare but serious side effect, and it is important for clinicians to have a high index of suspicion for this adverse reaction which occurs within 1 month after initiation of treatment for IBD.
Endoscopic ultrasound (EUS)-guided pancreatic cyst ablation with alcohol lavage or paclitaxel-based regimens are investigative modalities. To evaluate the safety and efficacy of EUS-guided pancreatic cyst ablation with alcohol lavage or paclitaxel-based regimens. A systematic review of computerized bibliographic databases was carried out for studies of EUS-guided pancreatic cyst ablation with alcohol lavage or paclitaxel-based regimens from January 1980 to February 2018. EUS-guided cyst ablation-related outcomes (cyst resolution) and complications. Data were extracted from six studies (N=207 patients) for EUS-guided cyst ablation with alcohol lavage and eight studies (N=347 patients) for EUS-guided cyst ablation with paclitaxel-based regimens. The pooled proportion of patients with complete cyst resolution was 68/207 (32.8%) for EUS-guided cyst ablation with alcohol lavage and 221/347 (63.6%) for EUS-guided cyst ablation with paclitaxel. Postablation adverse events with EUS-guided ablation with alcohol lavage were 44/207 (21.7%), and those with EUS-guided ablation with paclitaxel-based regimens were 52/347 (15%). Limitations of this study are because of the variability in study design and regimens tested, paucity of randomized trials, and differences in pancreatic cyst types receiving treatment. EUS-guided cyst ablation appears to be effective and safe. The effect on pancreatic cancer incidence is unknown; EUS-guided pancreatic cyst ablation modalities require further improvement and validation to determine their role in the treatment of patients with pancreatic cystic lesions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
