Assessment of nodal target definition and dosimetry using three different techniques: implications for re-defining the optimal pelvic field in endometrial cancer.

Purposes: 1. To determine the optimal pelvic nodal clinical target volume for post-operative treatment of endometrial cancer. 2.

Small-bowel obstruction associated with sigmoid diverticulitis: CT evaluation in 16 patients.

Objective: The purpose of this study was to identify acute sigmoid diverticulitis as a cause of small-bowel obstruction and to describe the CT findings.

Conclusion: CT scanning enabled accurate preoperative diagnosis of colonic diverticulitis as the cause of the small-bowel obstruction, thereby allowing proper management and surgical planning.

Prospective evaluation of colonic obstruction with computed tomography.

Background: To determine whether computed tomography (CT) can satisfactorily diagnose and evaluate patients with suspected colonic obstruction.

Methods: Seventy-five patients with suspected colonic obstruction were evaluated prospectively by CT and compared with the gold standards of surgery and/or endoscopy in 65 patients, clinical course in nine, and contrast enema (CE) in one. A limited comparison between CT and CE (26) patients was also made in those patients who had both studies.

Abdominal CT findings when the superior vena cava, brachiocephalic vein, or subclavian vein is obstructed.

Objective: We evaluated findings on contrast-enhanced abdominal CT scans that suggest obstruction of the superior vena cava, brachiocephalic vein, or subclavian vein.

Subjects And Methods: We conducted a retrospective review of 22 patients with superior vena caval, brachiocephalic vein, or subclavian vein obstruction and analyzed the upper abdominal images on a chest CT scan or an abdominal CT scan. We assessed collateral vessels in the upper abdomen to answer the following question: Did enhancement approach undiluted IV contrast or were there other findings? In the second part of our study, we conducted a prospective review of abdominal CT scans of 200 patients without known mediastinal disease or known upper extremity venous occlusion to determine the frequency of abnormal enhancement of these vessels in a healthy population.

Case report. Small bowel obstruction due to phytobezoar formation within Meckel diverticulum: CT findings.

Intestinal obstruction due to a phytobezoar within a Meckel diverticulum is exceedingly rare, with only seven reported cases in the surgical literature. The most important precipitating factor is the ingestion of agents high in fiber and cellulose. Small bowel obstruction in all but one case was due to retrograde propagation of the bezoar into the small bowel lumen.
