En bloc resection of the superior mesenteric vein (SMV), portal vein (PV), and/or splenic vein (SV) with concomitant venous reconstruction is required in 11-65 % of cases of locally advanced pancreatic cancer.1 Early retropancreatic dissection of the superior mesenteric artery (SMA) from behind the pancreatic head utilizing an 'artery first' approach has been reported to be an efficient and safe approach to pancreaticoduodenectomy when SMA involvement is suspected.2 Additionally, this technique has been shown to reduce blood loss and result in shorter PV clamp times.3 While there are multiple variations to 'artery first' resection,4 this video will illustrate the critical steps of using the 'posterior approach' in patients with locally advanced pancreatic cancer. This approach has the benefit of early identification of a replaced right hepatic artery, but may be difficult in obese patients or those with extensive peripancreatic inflammation. These difficulties may be overcome by utilizing an 'inferior supracolic (anterior) approach', but this necessitates early division of the pancreatic neck and stomach.5 METHODS: Select video clips were compiled from several pancreatoduodenectomies to demonstrate this technique. A variety of bipolar devices were utilized for dissection depending on surgeon preference. All patients were diagnosed with locally advanced pancreatic cancer by Americas Hepato-Pancreato-Biliary Association/Society of Surgical Oncology (AHPBA/SSO) consensus criteria, confirmed by biopsy, and completed neoadjuvant chemotherapy. Patients were restaged by pancreas protocol computed tomography scan at the end of chemotherapy and offered local resection if the tumor did not progress and they were medically fit. No Institutional Review Board approval was required. ⋯ The 'artery first' approach has been shown to be safe and feasible in pancreatic resections. This technique should be considered whenever tumor is thought to involve the SMV and/or PVs as a means to facilitate safe venous resection and reconstruction while preserving sound oncologic principles.

Although pancreatoduodenectomy (PD) with mesenterico-portal vein resection (VR) can be performed safely in patients with resectable pancreatic ductal adenocarcinoma (PDAC), the impact of this approach on long-term survival is controversial. ⋯ PD with VR has similar morbidity but worse OS compared with a PD-VR. Although VR is not predictive of survival, tumors requiring a PD+VR have more adverse biological features.

Patients with stage IV colorectal cancer and peritoneal carcinomatosis are increasingly treated with curative intent and perioperative systemic chemotherapy combined with targeted therapy. The aim of this study was to analyze the potential impact of bevacizumab on early morbidity after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with peritoneal carcinomatosis of colorectal origin. ⋯ Administration of bevacizumab before surgery with complete cytoreduction followed by HIPEC for colorectal carcinomatosis is associated with twofold increased morbidity. The oncologic benefit of bevacizumab before HIPEC remains to be evaluated.

The specific aim of this study was to conduct a systematic review of the literature to assess outcomes data on complications and aesthetic results associated with autologous tissue-based breast reconstruction performed before or after chest wall irradiation. ⋯ Review of the current literature suggests similar rates of complications and success rates in autologous breast reconstruction patients exposed to pre- or post-reconstruction radiation. Immediate autologous reconstruction should be considered as a viable option even in patients who are likely to require postmastectomy radiotherapy.

The perioperative coagulopathy, hemodynamic instability, and infectious complications that may occur during cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has raised concerns about the safety of epidural analgesia in patients undergoing such procedures. ⋯ With close hematologic monitoring and particular attention to sterility, epidural analgesia can be safely provided to patients undergoing CRS with HIPEC. Early initiation of continuous epidural infusions during surgery could lead to decreased blood loss and less intraoperative fluid administration. Prospective randomized studies are required to further investigate these potential benefits.
