Preoperative Nutritional Optimization of the Oncology Patient: A Scoping Review.

Background: Malnutrition is common among patients with cancer and is a known risk factor for poor postoperative outcomes; however, preoperative nutritional optimization guidelines are lacking in this high-risk population. The objective of this study was to review the evidence regarding preoperative nutritional optimization of patients undergoing general surgical operations for the treatment of cancer.

Methods: A literature search was performed across the Ovid (MEDLINE), Cochrane Library (Wiley), Embase (Elsevier), CINAHL (EBSCOhost), and Web of Science (Clarivate) databases.

Performance of a novel temporary arterial shunt in a military-relevant controlled hemorrhage swine model.

Background: In military trauma, temporary vascular shunts restore arterial continuity until delayed vascular reconstruction, often for a period of hours. A novel US Air Force-developed trauma-specific vascular injury shunt (TS-VIS) incorporates an accessible side port for intervention or monitoring, which may improve patency under adverse hemodynamic conditions. Our objective was to evaluate TS-VIS patency in the setting of volume-limited resuscitation from hemorrhagic shock.

Conversion of the Abdominal Aortic and Junctional Tourniquet (AAJT) to Infrarenal Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) Is Practical in a Swine Hemorrhage Model.

Background: Two methods of controlling pelvic and inguinal hemorrhage are the Abdominal Aortic and Junctional Tourniquet (AAJT; Compression Works) and resuscitative endovascular balloon occlusion of the aorta (REBOA). The AAJT can be applied quickly, but prolonged use may damage the bowel, inhibit ventilation, and obstruct surgical access. REBOA requires technical proficiency but avoids many of the complications associated with the AAJT.

Therapeutic cardiac arrest as an adjunct to resuscitative endovascular balloon occlusion of the aorta: Bridging the gap from fatal hemorrhage to definitive surgical control in swine.

Background: Uncontrolled hemorrhage is the leading cause of potentially survivable combat casualty mortality, with 86.5% of cases resulting from noncompressible torso hemorrhage. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a minimally invasive technique used to stabilize patients with noncompressible torso hemorrhage; however, its application can take an average of 8 minutes to place.

Noninvasive Cerebral Perfusion and Oxygenation Monitoring Augment Prolonged Field Care in a Non-Human Primate Model of Decompensated Hemorrhage and Resuscitation.

Background: Decompensated hemorrhagic shock (DHS) is the leading cause of preventable death in combat casualties. "Golden hour" resuscitation effects on cerebral blood flow and perfusion following DHS in prolonged field care (PFC) are not well investigated. Using an established non-human primate model of DHS, we hypothesized noninvasive regional tissue oxygenation (rSO2) and Transcranial Doppler (TCD) would correlate to the invasive measurement of partial pressure of oxygen (PtO2) and mean arterial pressure (MAP) in guiding hypotensive resuscitation in a PFC setting.

Resuscitative endovascular balloon occlusion of the aorta for thoracic trauma in the setting of platelet dysfunction: A translational swine study.

Background: In patients with noncompressible torso hemorrhage, antiplatelet medications may lead to worse outcomes. Resuscitative endovascular balloon occlusion of the aorta (REBOA) may potentially stabilize these patients, but currently, major thoracic bleeding is a contraindication. The goal of this study was to determine if REBOA use for shock with major thoracic bleeding has worse outcomes in the setting of platelet dysfunction (PD).

Resuscitative endovascular balloon occlusion of the aorta for thoracic trauma: A translational swine study.

Unlabelled: Noncompressible torso hemorrhage in trauma is particularly lethal. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has the potential to stabilize these patients, but currently is contraindicated for major thoracic bleeding. The goal of this study was to evaluate the effect of REBOA on the hemodynamic and metabolic profile as well as its effect on early survival in a porcine model of thoracic hemorrhage and shock.

Clinical and Quality of Life Assessment of Patients Undergoing Laparoscopic Hiatal Hernia Repair.

Hiatal hernia repair (HHR) and fundoplication are similarly performed among all hiatal hernia types with similar techniques. This study evaluates the effect of HHR using a standardized technique for cruroplasty with a reinforcing polyglycolic acid and trimethylene carbonate mesh (PGA/TMC) on patient symptoms and outcomes. A retrospective review of patient perioperative characteristics and postoperative outcomes was conducted for cases of laparoscopic hiatal hernia repair (LHHR) using a PGA/TMC mesh performed over 21 months.

Compliance of the abdominal wall during laparoscopic insufflation.

Background: To provide adequate workspace between the viscera and abdominal wall, insufflation with carbon dioxide is a common practice in laparoscopic surgeries. An insufflation pressure of 15 mmHg is considered to be safe in patients, but all insufflation pressures create perioperative and postoperative physiologic effects. As a composition of viscoelastic materials, the abdominal wall should distend in a predictable manner given the pressure of the pneumoperitoneum.

Quality-of-life scores in laparoscopic preperitoneal inguinal hernia repair.

Background: Published support exists for using lightweight polypropylene mesh (PPM) to repair inguinal hernias with increased biocompatibility and decreased foreign body reaction and pain. However, quality of life (QOL) has not been assessed. We assess QOL in patients undergoing laparoscopic totally extraperitoneal hernia repair (TEP) with lightweight PPM.
