Abdominal computed tomographic scan in the selection of XXXX with @entity298 for cytoreductive surgery.

@entity1 @entity5 @entity189 @entity298
BACKGROUND: Cytoreductive surgery and intraperitoneal chemotherapy have been used to treat peritoneal @entity189 . A complete surgical resection is required for optimal results to be achieved. This study evaluated the preoperative computed tomographic (CT) findings in @entity1 with @entity298 in order to predict the probability of a complete resection. STUDY DESIGN: Computed tomographic scans of the abdomen and pelvis were reviewed retrospectively in 45 @entity1 with a diagnosis of @entity298 who were treated with surgery and intraperitoneal chemotherapy. According to the completeness of cytoreduction, @entity1 were divided into two groups. @entity1 in the first group (n = 25) had complete cytoreduction (CR) with no @entity5 deposits 2.5 mm in diameter or larger left behind. The surgical resection of @entity5 was incomplete in the second group of @entity1 (n = 20). Sixteen CT parameters were initially examined in each group of @entity1 and statistically evaluated according to the completeness of the cytoreductive surgical procedure. RESULTS: The incidences of six CT findings were significantly different in the two groups of @entity1 . These findings were: @entity5 volume in small bowel mesentery (p < 0.001), @entity5 volume in proximal jejunum (p = 0.003), @entity5 volume in distal jejunum (p = 0.002), @entity5 volume in proximal ileum (p = 0.003), mesentery configuration (p < 0.001), and obstruction of @entity5 (p < 0.001). A statistical approach using a tree-structured diagram showed that @entity1 with both obstruction of @entity5 and @entity5 diameter greater than 0.5 cm on small bowel surfaces exclusive of distal ileum on preoperative CT scan, had an 88 percent probability of incomplete resection. @entity1 without these two CT findings had a 92 percent probability of complete resection. CONCLUSIONS: This study shows that selection criteria for @entity1 with @entity298 are available on a preoperative CT scan of the abdomen and pelvis. @entity1 whose scans @entity5 and @entity5 diameter greater than 0.5 cm on small bowel surfaces exclusive of distal ileum are unlikely to be candidates for cytoreductive surgery for the treatment of peritoneal @entity189 .
