Sessile Serrated Lesion of the Appendix in a Teenage Girl.

According to the literature, serrated lesions and polyps of the appendix are extremely rare in children or teenagers. Herein, we present the pathologic and molecular features of a sessile serrated lesion (SSL) that was incidentally found in the appendix of a teenage girl. Our findings not only illustrate that appendiceal SSL may occur in young patients such as teenagers but also confirm further that V600E mutation may be found in a subset of these neoplastic lesions.

Chronic stomal variceal bleeding after colonic surgery in patients with portal hypertension: efficacy of beta-blocking agents?

In patients with portal hypertension, ileostomy or colostomy carries the risk of the development of stomal varices at the site of the mucocutaneous junction of a stoma. Such varices are often the source of difficult-to-treat recurrent or chronic bleeding. In this setting, transjugular intrahepatic portosystemic shunt insertion and embolisation is considered the best therapeutic approach in spite of relatively high mortality and morbidity rates.

[Drainage-lavage and closure of a late esophageal perforation with esophagopleural fistula and encysted pleural effusion after endoscopic injection sclerotherapy for varices].

We report a case of late perforation of the thoracic esophagus with an esophagopleural fistula after endoscopic sclerotherapy for esophageal varices in a Child-Pugh B9 cirrhotic patient. The existence of a thoracic empyema without diffuse mediastinitis allowed management of the fistula by percutaneous drainage-lavage and antibiotic therapy with subsequent closure of the esophageal wall defect and recovery from sepsis. This observation indicates that minimally invasive management of an esophageal perforation complicated by an esophago-pleural fistula is possible in highly selected patients.
