Assess the impact of preoperative serum antitumor necrosis factor-α (anti-TNFα) drug levels on 30-day postoperative morbidity in inflammatory bowel disease (IBD) patients. ⋯ Increasing preoperative serum anti-TNFα drug levels are associated with adverse postoperative outcomes in CD but not UC patients.

This study aimed to determine the prognostic significance of extramural venous invasion (EMVI) after chemoradiotherapy (CRT) by both magnetic resonance imaging (MRI) (ymrEMVI) and histopathology (ypEMVI). ⋯ Detection of EMVI post-CRT is prognostically significant whether detected by MRI or histopathology. EMVI status after treatment may be used to counsel patients regarding ongoing risks of metastatic disease, implications for surveillance, and systemic chemotherapy.

To assess the long-term survival and quality of life in total pancreatectomies and to identify risk factors for perioperative morbidity and mortality. ⋯ Standard total pancreatectomy, if needed, is associated with good long-term outcome in pancreatic cancer. Marked surgical morbidity and impaired survival associated with vascular resections reflect the invasiveness of extended total pancreatectomies and the underlying advanced malignant disease.

The aim of this study was to demonstrate lymphatic isolation in a model of hind limb lymph node (LN) excision, consisting of ipsilateral popliteal and inguinal LN excision and to evaluate the immunologic response to allogeneic skin transplanted onto this region of lymphatic isolation. ⋯ Lymph node excision completely interrupts lymphatic flow of the hind limb. This model of lymphatic isolation impairs the ability of the transplant recipient to acutely mount a Th1 or Th2 response to allogeneic skin transplants.
