Natural Orifice Transluminal Endoscopic Surgery (NOTES) is an evolving experimental field exploring the technical feasibility and outcome of therapeutic interventions performed through the natural orifices of the body. The knowledge accumulating in NOTES is the result of animal experimentation and ongoing early clinical experience in humans. In this report we describe a patient treated with tra...

Rectal atresia (RA) with a normal anus is a rare anomaly. We describe a case of rectal atresia in a newborn male presenting with an abdominal distension and failure of passing meconium. The rectal atresia was primarily operated by transanal route.

Widespread popularity of the double-stapler technique has created the potential for anal sphincter and anal canal injury during transanal insertion of the end-to-end anastomosing stapler. The Faensler operating anoscope helps eliminate that potential by symmetrically dilating the anal canal, thereby permitting atraumatic insertion of the end-to-end anastomosing stapler.

An 89-year-old male, with rectal adenocarcinoma, stage IIA, treated with transanal resection, end anastomosis and radiotherapy is reported. At the last follow-up, he shows significant elevation of CEA serum levels, changes in bowel and an extraparietal rectal nodule. 18F-FDG PET/CT scan showed a tumor local recurrence, pelvic lymph node involvement, peritoneal metastatic implants and liver meta...

Transanal endoscopic microsurgery (TEM) is a well-established surgical approach for certain benign or early malignant lesions of the rectum under specific indications. The skill required in performing the procedure and the prolonged learning curve period necessitate an experienced surgeon. Furthermore, the procedure is known as expensive for a health care system. We describe a novel hybrid tech...

Rectal gastrointestinal stromal tumours (GISTs) are uncommon tumours and usually present with large sizes. We present two cases of rectal GIST. Imatinib was used in the setting of neoadjuvant and adjuvant therapy. Both tumours were resected transanally by the transanal endoscopic operation (TEO) platform. Oncosurgeons are recommended to implement sphincter-sparing surgeries for these cases.
