Treatment of surgical disease in the gravid patient requires a unique and careful approach where safety of the mother and fetus are both considered. Approaches to diagnosis and therapy of surgical disease in the gravid patient are increasingly clarified and defined in the literature. Laparoscopy, once described as contraindicated in pregnancy, has been steadily accepted and applied as data supporting its safety and use have accumulated. An extensive review of the literature was performed to define the use of laparoscopy in pregnancy. Diagnoses for independent surgical diseases as well as imaging modalities and techniques during pregnancy are reviewed. Preoperative, intraoperative, and postoperative management of the pregnant patient are described and evaluated with focus on use of laparoscopy. Literature supporting safety and efficacy of laparoscopy in cholecystectomy, appendectomy, solid organ resection, and oophorectomy in the gravid patient is outlined. Based on level of evidence, this review includes recommendations specific to surgical approach, trimester of pregnancy, patient positioning, port placement, insufflation pressure, monitoring, venous thromboembolic prophylaxis, obstetric consultation, and use of tocolytics in the pregnant patient.

Delivery of the hypoxia inducible vascular endothelial growth factor (RTP-VEGF) plasmid using a novel reducible disulfide poly(amido ethylenediamine) (SS-PAED) polymer carrier was studied in vitro and in vivo. In vitro transfection of primary rat cardiomyoblasts (H9C2) showed SS-PAED at a weighted ratio of 12:1 (polymer/DNA) mediates 16 fold higher expression of luciferase compared to an optimized bPEI control. FACS analysis revealed up to 57 ± 2% GFP positive H9C2s. The efficiency of plasmid delivery to H9C2 using SS-PAED was found to depend upon glutathione (GSH) levels inside the cell. SS-PAED mediated delivery of RTP-VEGF plasmid produced significantly higher levels of VEGF expression (up to 76 fold) under hypoxic conditions compared to normoxic conditions in both H9C2 and rat aortic smooth muscle cells (A7R5). Using SS-PAED, delivery of RTP-VEGF was investigated in a rabbit myocardial infarct model using 100 μg RTP-VEGF. Results showed up to 4 fold increase in VEGF protein expression in the region of the infarct compared to injections of SS-PAED/RTP-Luc. In conclusion, SS-PAED mediated therapeutic delivery improves the efficacy of ischemia-inducible VEGF gene therapy both in vitro and in vivo and therefore, has potential for the promotion of neo-vascular formation and improvement of tissue function in ischemic myocardium.

Pancreatectomies are high-risk operations with substantial perioperative morbidity and mortality. Risk-adjusted outcomes for patients treated at PS hospitals were found to be superior to those for patients treated at VA hospitals in the study.

The addition of ketorolac to lidocaine for ankle block contributed to longer duration and better quality analgesia after foot surgery compared with plain 1.73% lidocaine or 1.73% lidocaine plus intravenous ketorolac. The ethanol vehicle is unlikely responsible for the analgesic effects of ketorolac. Ketorolac retains its chemical stability when placed in local solutions of lidocaine or bupivacaine.
