The objective of this retrospective study was to evaluate the influence of neoadjuvant systemic chemotherapy on patients with colorectal carcinomatosis before a curative procedure. ⋯ In patients with PC from colorectal cancer without extraperitoneal metastases, failure of neoadjuvant systemic chemotherapy should not constitute an absolute contraindication to a curative procedure combining CRS and HIPEC.

Because of its retrospective character, the classification system of the International Study Group of Pancreatic Fistula (ISGPF) lacks prognostic capacity regarding fistula-related complications. This study aimed to evaluate the options and limitations of the ISGPF classification system and to identify risk factors with respect to clinical decision making. ⋯ The ISGPF classification system has its limitations in clinical decision making, because it does not adequately describe a large subgroup of patients. To improve clinical decision making about management of patients, it is crucial that the ISGPF classification system is merged with newer clinical data.

To investigate the mechanism of propranolol on regression of infantile hemangiomas. ⋯ Collectively, these data suggest that propranolol exerts its suppressive effects on hemangiomas through the HIF-1α-VEGF-A angiogenesis axis, with effects mediated through the PI3/Akt and p38/MAPK pathways. These findings provide a plausible mechanism of action of propranolol on regression of infantile hemangiomas.

Esophagectomy is a complex operation and is associated with significant morbidity and mortality. In an attempt to lower morbidity, we have adopted a minimally invasive approach to esophagectomy. ⋯ MIE in our center resulted in acceptable lymph node resection, postoperative outcomes, and low mortality using either an MIE-neck or an MIE-chest approach. The MIE Ivor Lewis approach was associated with reduced recurrent laryngeal nerve injury and mortality of 0.9% and is now our preferred approach. Minimally invasive esophagectomy can be performed safely, with good results in an experienced center.

Inflammatory bowel diseases are costly chronic gastrointestinal diseases. We aimed to determine whether immediate colectomy with ileal pouch-anal anastamosis (IPAA) after diagnosis of severe ulcerative colitis (UC) was cost-effective compared to the standard medical therapy. ⋯ Under the appropriate clinical settings, early colectomy with IPAA after diagnosis of severe UC reduces health care expenditures and provides comparable quality of life compared to exhaustive standard medical therapy.
