Total Pancreatectomy for Locally Advanced Pancreatic Adenocarcinoma with Coeliac Trunk Resection and Retrograde Gastric Revascularization Through Aorto-Hepato-Spleno Allograft.
Ann Surg Oncol

Department of HPB Surgery and Liver Transplantation, Hôpital Beaujon, Assistance Publique-Hôpitaux de Paris (AP-HP), Université de Paris-Cité, Clichy, France.
Background: Locally advanced pancreatic adenocarcinomas (LA-PDAC) are more frequently operated now than in the past because of new regimen chemotherapy and improvement in surgical technique. Resection of the coeliac trunk (CT) during pancreatoduodenectomy (PD) or total pancreatectomy (TP) is not routinely done owing to the risk of liver and gastric ischaemia. In this video, a patient with LA-PDAC underwent TP with CT resection and retrograde gastric revascularization through the distal splenic artery.

Introduction: Surgeries in the occipitocervical and upper cervical region are always quite challenging and need adequate surgical experience and expertise. Especially in cases, where both anterior and posterior surgical access is required, complication rates could be significantly high. The transoral approach for the ventral pathologies of the upper cervical region has been previously described using the conventional open technique where post-operative morbidity is a concern.

Introduction: Primary bladder neck obstruction (PBNO) is a rare but significant cause of BOO and LUTS in females, with unclear etiology involving theories of fibrotic narrowing, tissue hyperplasia, or muscle abnormalities. Due to nonspecific symptoms, PBNO diagnosis remains challenging, and optimal surgical treatment needs to be better defined.
Case Presentation: We report two cases of females in their 50s with recurrent urinary retention managed by indwelling catheters.
Establishment of a survival rabbit model for laryngotracheal stenosis: A prospective randomized study.
Laryngoscope Investig Otolaryngol

National Engineering Research Center of Light Alloy Net Forming, State Key Laboratory of Metal Matrix Composites, School of Materials Science and Engineering Shanghai Jiao Tong University Shanghai China.
Objective: To develop a reproducible survival rabbit model for laryngotracheal stenosis (LTS).
Methods: Seventy New Zealand white (NZW) rabbits were randomly divided into experimental groups ( = 30) and a control group ( = 40). In experimental groups, a nylon brush was inserted retrograde from the tracheotomy through the subglottis and rotated until a full layer circumferential mucosal injury to cartilage exposure, assisted by fiberoptic laryngoscopy (FOL) visualization.
Mechanical properties of snake skin vary longitudinally, following large prey ingestion and among species.

The ability for snakes to ingest large prey (macrostomy) is a widespread, derived trait that involves distending the skin during ingestion and metabolic upregulation during digestion. The material behavior of the skin must accommodate significant stretch associated with a large prey bolus, but data remain sparse for how the material properties of snake skin vary: longitudinally within an individual, after ingesting large prey and among species. To test whether these three factors affected the mechanical properties of snake skin, we quantified uniaxial stresses and strains in circumferential loops of skin from the neck, mid-body and tail of fasted and recently fed Boa constrictor.
