Tailgut cyst or retrorectal cystic hamartoma is a rare congenital lesion, thought to arise from a portion of the embryological hindgut, usually benign, with no or unspecific symptoms, mainly diagnosed in middle-aged women. Complete surgical resection of the cyst is recommended to avoid complications and confirm the diagnosis. In this report, we present our experience in the successful endoscopic management of a tailgut cyst, outlining the endoscopic resection technique and discussing under what conditions this approach may be applicable.

- Undifferentiated early gastric cancer (UD-EGC) can be treated effectively with endoscopic submucosal dissection (ESD), and this study focused on understanding recurrence rates and risk factors related to this treatment.
- Data was gathered from 17 centers, involving 71 patients, indicating a low recurrence rate of 5.6% after an average follow-up period of about 29 months.
- Factors like lymphovascular and perineural invasion were found to be significantly linked to local recurrence, while lesion size was not a predictor, suggesting that ESD is a viable initial treatment option for UD-EGC when certain risk factors are absent.
