Seroma is a frequent problem after mastectomy (ME) and axillary lymph node dissection (ALND). Seroma is associated with pain, discomfort, impaired mobilisation and repeated aspirations, often resulting in a surgical site infection (SSI). It has already been demonstrated that minimizing dead space through fixation of the skin flaps to the underlying muscles (quilting) lowers the incidence of seroma. The aim of this study was to evaluate the effect of quilting on the incidence of seroma, and SSI. ⋯ Quilting is an effective method for preventing seroma and its complications.

Stroke volume variation in hepatic resection: a replacement for standard central venous pressure monitoring.
Central venous pressure (CVP) is the standard method of volume status evaluation during hepatic resection. CVP monitoring requires preoperative placement of a central venous catheter (CVC), which can be associated with increased time, cost, and adverse events. Stroke volume variation (SVV) is a preload index that can be used to predict an individual's fluid responsiveness through an existing arterial line. The purpose of this study was to determine if SVV is as safe and effective as CVP in measuring volume status during hepatic resection. ⋯ SVV can be used safely as an alternative to CVP monitoring during hepatic resection with equivalent outcomes in terms of blood loss and parenchymal transection time. Using SVV as a predictor of fluid status could prove to be advantageous by avoiding the need for CVC insertion and therefor eliminating the risk of CVC related complications in patients undergoing hepatic resection.

Peritoneal carcinomatosis (PC) is an unmet medical need. Despite recent improvements, systemic chemotherapy has limited efficacy. We report the first application of intraperitoneal chemotherapy as a pressurized aerosol in human patients. ⋯ PIPAC shows superior pharmacological properties with high local concentration and low systemic exposure. PIPAC can induce regression of PC in chemoresistant tumors, using 10% of a usual systemic dose.

Peritoneal metastasis of gastric cancer has extremely poor clinical outcomes. Recently, we developed a combination chemotherapy that used intraperitoneal (IP) paclitaxel (PTX) and produced excellent antitumor effects against peritoneal lesions. However, no information is available about the benefit of gastrectomy in cases with malignant ascites. ⋯ Salvage gastrectomy after chemotherapy of S-1 with IV and IP PTX is promising, even for patients with highly advanced gastric cancer and severe peritoneal metastasis and malignant ascites.

Neoadjuvant chemoradiation and chemotherapy provided for borderline or locally advanced, potentially resectable pancreatic adenocarcinoma improves resectability rates. Response to therapy is also an important prognostic factor. There are no data in the literature regarding optimal time interval or duration of chemotherapy after chemoradiation before surgery, and pathologic response rates. Using our database, we evaluated these relationships and the effect on overall and progression-free survival. ⋯ Patients who underwent a prolonged time interval after neoadjuvant chemoradiation with ongoing chemotherapy were more likely to have an improved pathologic response at time of surgical resection, which was associated with improved median overall survival.
