Successful endoscopic treatment of an esophageal duplication cyst.

Duplication cysts of the gastrointestinal tract are rare, particularly in adults. Endoscopic minimally invasive treatment is still a challenging approach even in the endoscopically accessible sections of the gastrointestinal tract. In a 25-year-old patient suffering from dysphagia, an endoscopy and subsequent endosonography revealed a spherical duplication cyst in the lower third of the esophagus, which prompted us to puncture the cyst and subsequently to perform a fenestration (marsupialization; diameter 1 cm) in the anterior wall of the cyst, resulting in permanent drainage of the cystic fluid.

Intrasurgical pancreas cytology.

Introduction: A differential therapy of chronic pancreatitis and carcinoma calls for evaluation of the validity of findings. Presurgical suspicion of a carcinoma often requires intrasurgical diagnostics such as excisional biopsies, punch biopsies, and fine-needle aspiration cytology (FNAC) for confirmation.

Aims: To evaluate FNAC as an intraoperative diagnostic method of very high probability.
