Transanal-transrektale endoskopische Resektion einer Schwanzdarmzyste
摘要
Tailgut cysts are a residual of the embryonic development and are a rare primarily benign finding in the retrorectal space but they have the potential of becoming malignant. The majority of patients are asymptomatic but symptoms may occur due to the space-occupying effect. Based on a case report the transanal transrectal endoscopic resection with the transanal endoscopic microsurgery (TEM) instruments is described and the necessary diagnostics and possible surgical strategies are discussed.
