Watch-and-wait has emerged as a new strategy for the management of rectal cancer when a complete clinical response is achieved after neoadjuvant therapy. In an attempt to standardize this new clinical approach, initiated by the Spanish Cooperative Group for the Treatment of Digestive Tumors (TTD), and with the participation of the Spanish Association of Coloproctology (AECP), the Spanish Society of Pathology (SEAP), the Spanish Society of Gastrointestinal Endoscopy (SEED), the Spanish Society of Radiation Oncology (SEOR), and the Spanish Society of Medical Radiology (SERAM), we present herein a consensus on a watch-and-wait approach for the management of rectal cancer. We have focused on patient selection, the treatment schemes evaluated, the optimal timing for evaluating the clinical complete response, the oncologic outcomes after the implementation of this strategy, and a protocol for surveillance of these patients.

Endoscopic retrograde cholangiopancreatography (ERCP) with cholangioscopy is the standard of care in the presence of large stones, with a success rate close to 80% in managing migration of clips-related stones [[3]]. Distal common bile duct (CBD) is normal, and pancreatic duct is slightly dilated Graph: Fig. 1 Magnetic resonance (MR) cholangiography showing a dilated intrahepatic bile duct and a large stone probably in remnant cystic duct with a 23 mm diameter.
