Radical surgery-peritonectomy with HIIQ has been shown to be a surgical procedure with high tolerability, low morbimortality, enhanced survival, and prolonged disease-free interval in patients with peritoneal carcinomatosis so much for recurrent or primary ovarian cancer.
HIPEC is a complement to radical surgery/ peritonectomy, which has been shown to be a surgical procedure with high tolerability, low morbimortality, enhanced survival and prolonged disease-free interval in patients with peritoneal carcinomatosis for recurrent ovarian cancer.
There is not unanimous agreement in the literature regarding the effects of bleeding on pulmonary gas exchange in polycythemic patients. Spirometry, alveolar-arterial O2 and CO2 tension differences, PaO2 breathing 100% oxygen and carbon monoxide-diffusing capacity were measured before and after 1 week of chronic phlebotomy in 4 chronic mountain polycythemic patients. Studies were carried out at 3,700 m above sea level (PB = 491 mm Hg). Before phlebotomy, 2 patients showed abnormal spirometry and gas exchange. Only 1 patient had high PaCO2 and all of them showed low values of PaO2 breathing oxygen. Phlebotomy improved both spirometry and gas exchange. Improvement in arterial oxygen saturation and PaO2 could not be attributed to changes in alveolar ventilation, but rather to better distribution of VA/QC ratios since physiological dead space decreased. Our results are similar to those reported in polycythemia vera patients. A significant correlation between the changes in PaO2 with phlebotomy and the control PaO2 have been found from 45 polycythemic patients with chronic obstructive pulmonary disease collected from the literature. It is concluded that excessive polycythemia worsened hypoxemia and that phlebotomy improved gas exchange.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
