We aimed to prospectively evaluate NIR-C, VR-AR, and x-ray intraoperative cholangiography (IOC) during robotic cholecystectomy. ⋯ This high-tech protocol illustrates the multimodal imaging of biliary anatomy towards precision cholecystectomy. Those visualization techniques could complement to reduce the likelihood of biliary injuries (NCT01881399).

The paper evaluates the application of a mixed reality (MR) headmounted display (HMD) for the visualization of anatomical structures in complex visceral-surgical interventions. A workflow was developed and technical feasibility was evaluated. ⋯ MR technology has a high potential to improve the surgeon's action and perception in open visceral surgery by displaying 3D anatomical models close to the surgical site. Superimposing anatomical structures directly onto the organs within the surgical site remains challenging, as the abdominal organs undergo major deformations due to manipulation, respiratory motion, and the interaction with the surgical instruments during the intervention. A further application scenario would be intraoperative ultrasound examination displaying the image directly next to the transducer. Displays and sensor-technologies as well as biomechanical modeling and object-recognition algorithms will facilitate the application of MR-HMD in surgery in the near future.

During the last decade, face allotransplantation has been shown to be a revolutionary reconstructive procedure for severe disfigurements. However, offer to patients remains limited due to lifelong immunosuppression. To move forward in the field, a new pathway in tissue engineering is proposed. ⋯ Complex acellular facial scaffolds were obtained, preserving simultaneously a cell-friendly extracellular matrix and a perfusable vascular tree. This step will enable further engineering of postmortem facial grafts, thereby offering new perspectives in composite tissue allotransplantation.

Multicenter Study Comparative Study
Survival Benefit of Neoadjuvant Treatment in Clinical T3N0M0 Esophageal Cancer: Results From a Retrospective Multicenter European Study.
Based on current guidelines, clinical T3N0M0 esophageal tumors may or may not receive neoadjuvant treatment, according to their perception as locally advanced (cT3) or early-stage tumors (stage II). The study aim was to assess the impact of neoadjuvant treatment upon survival for cT3N0M0 esophageal cancer patients, with subgroup analyses by histological type (squamous cell carcinoma vs adenocarcinoma) and type of neoadjuvant treatment (chemotherapy vs radiochemotherapy). ⋯ Neoadjuvant treatment offers a significant survival benefit for clinical T3N0M0 esophageal cancer.

Multicenter Study Comparative Study
Transanal Versus Transabdominal Minimally Invasive (Completion) Proctectomy With Ileal Pouch-anal Anastomosis in Ulcerative Colitis: A Comparative Study.
This study aims to compare surgical outcome of transanal ileal pouch-anal anastomosis (ta-IPAA) with transabdominal minimal invasive approach in ulcerative colitis (UC), using the comprehensive complication index (CCI). ⋯ Ta-IPAA for UC is a safe procedure, resulting in fewer patients with morbidity, but comparable CCI when morbidity is present. Overall, ta-IPAA led to lower CCI scores.
