During the past decade, intraperitoneal therapy of ovarian cancer has evolved from a pharmacologic model into an established treatment technique for women with this malignancy. Approximately 40% of patients with small-volume residual ovarian cancer (microscopic disease or macroscopic tumor, < or = 0.5 cm in maximum tumor diameter), after an objective response to initial organoplatinum-based sys...

An investigation is reported of a comparison by three methods of the degree and certainty of differentiation of strains of S. typhosa of different virulence for mice. These methods were (a) intracerebral injection, (b) intraperitoneal injection of saline suspensions, and (c) intraperitoneal injection of mucin suspensions of the test organisms. With the strains of S. typhosa employed, differenti...

BACKGROUND The prognosis of patients with peritoneal tumors has been improved by the association of cytoreductive surgery with hyperthermic intraperitoneal chemotherapy, though still with an unclear impact on patients' quality of life. The purpose of our study was to evaluate the quality of life in 18 cases submitted to cytoreductive surgery and hyperthermic intraperitoneal chemotherapy and par...

Colon perforation is an uncommon but serious complication of colonoscopy. It may occur as either intraperitoneal or extraperitoneal perforation or in combination. The majority of colonic perforations are intraperitoneal, causing air and intracolonic contents to leak into the peritoneal space. Rarely, colonic perforation can be extraperitoneal, leading to the passage of air into the retroperiton...

Of all the hernia varieties, groin hernias are most prevalent. A gap in endo-abdominal fascia known as an inguinal is large enough to allow evacuation of intraperitoneal or preperitoneal contents into groin.

BACKGROUND Clinical data indicate that laparoscopic surgery reduces postoperative inflammatory response and benefits patient recovery. Little is known about the mechanisms involved in reduced systemic and local inflammation and the contribution of reduced trauma to the abdominal wall and the parietal peritoneum. METHODS Included were 61 patients, who underwent elective colorectal resection wi...

The current enhanced permeability and retention (EPR)-based approved nanomedicines have had little impact in terms of prolongation of overall survival in patients with cancer. For example, the two Phase III trials comparing Doxil(®), the first nanomedicine approved by the US Food and Drug Administration, with free doxorubicin did not find an actual translation of the EPR effect into a statistic...

Central and intraperitoneal C75, an inhibitor of fatty acid synthase and stimulator of carnitine palmitoyl-transferase-1, inhibits eating in mice and rats. Mechanisms involved in feeding inhibition after central C75 have been identified, but little is yet known about how systemic C75 might inhibit eating. One issue is whether intraperitoneal C75 reduces food intake in rats by influencing normal...

BACKGROUND We aimed to compare plasma concentrations of carbon dioxide (CO(2)) in dogs that underwent intra- and preperitoneal CO(2) insufflation. MATERIALS AND METHODS Thirty dogs were studied. Ten formed a control group, 10 underwent intraperitoneal CO(2) insufflation, and 10 underwent preperitoneal CO(2) insufflation. General anesthesia with controlled ventilation was standardized for all ...

Local-regional and peritoneal metastases still develop despite improvements in surgical techniques. Intraperitoneal chemotherapy has been proved to be effective in reducing the rate of local-regional and peritoneal metastases in many malignancies. There is adequate evidence that intraperitoneal perioperative chemotherapy after aggressive resection of locally advanced tumors of the digestive sys...
