This article reports an incidental finding of leptospirosis during a special consultation, which was initiated due to the pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The focus on SARS-CoV‑2 and the uncharacteristic symptoms of these two diseases make it much more difficult to find the correct diagnosis. Leptospirosis is predominantly a tropical zoonosis but also occurs in Germany.

The spectrum of endoscopic techniques has been greatly enlarged in recent years. Lesions and also (iatrogenic) complications that required surgical procedures in the past can now often be treated endoscopically. Advances in endoscopic mucosal resection and submucosal dissection also enable the resection of large or laterally spreading polyps in the gastrointestinal tract. ⋯ By the creation of a submucosal tunnel submucosal lesions can be completely excised and the muscle fibers of the lower esophageal sphincter can be endoscopically severed in achalasia patients. Endosonography-guided interventions have developed into the standard procedure for complicated pancreatitis and the use of cholangioscopy offers new therapeutic procedures for the bile and pancreatic ducts. In this continuing medical education article interventional endoscopic techniques are presented and critically evaluated.
