[Robotic-assisted surgery of rectal cancer-Technique, limitations and results].

Background: The number of oncological robotic-assisted rectal cancer resections is rapidly increasing in Germany and worldwide; however, the indications, technique and potential limitations of this surgical technique are still discussed.

Material And Methods: The standardized modular surgical technique, the results in our clinic and the currently published evidence are presented.

Results: The procedure should be divided into seven modules in terms of standardization and teaching.

Carcinoma cunniculatum on the shoulder: an atypical localisation of a verrucous carcinoma.

Carcinoma cunniculatum is a rarely occurring type of verrucous carcinoma (VC) which is considered a low-grade variant of squamous cell carcinoma. The tumour usually appears in the oral, genitogluteal, and plantar region; however, potentially it can arise anywhere on the skin. Carcinoma cunniculatum on the shoulder is a very rare manifestation with only two cases being reported in the literature.

Anatomical basis and clinical application of the infragluteal perforator flap.

Background: When selecting flaps for coverage of pressure ulcers of the sacrum and perineal region in paraplegic patients, long-term high recurrence rates should be considered. Therefore, the authors developed an infragluteal perforator flap to avoid "burning bridges" for future reconstruction.

Methods: Infragluteal perforator flaps were dissected in five fresh human cadavers to define the anatomy of the cutaneous branches of the descending branch of the inferior gluteal artery and cluneal nerves and define anatomical landmarks for clinical application.

The prepuce as a donor site for reconstruction of an extravasation injury to the foot in a newborn.

Extravasation injury is a common event in pediatric intensive-care units. This is the first report of successful utilization of the prepuce as a skin graft to reconstruct a full thickness skin necrosis due to a phenobarbital extravasation to the forefoot of a newborn.
