Standard therapy of enterocutaneous (ECF) and colocutaneous (CCF) fistulas consists of "conservative" management, with surgery reserved for failures of maximal medical treatment. We conducted a five-year retrospective review of 28 patients with low-output ECF and CCF to determine the outcome of early surgical and nonsurgical treatment of these conditions. Twelve men and 16 women with a mean age of 60 years presented with 22 ECF and 6 CCF. Six patients had early operative intervention in an attempt to close their fistulas, while the remaining 22 patients were treated without surgery. In addition, four of the nonsurgical group received parenteral somatostatin analog (SA). None of the surgical patients was septic preoperatively (mean WBC = 9.7), the mean preoperative hospital stay was 11 days, and no patients required a proximal diverting stoma. All of the surgical group resumed normal gastrointestinal function within two weeks, and seven of the nine (78 percent) demonstrated no recurrence of the fistula at a mean follow-up of 8.3 months. Of the 22 medically treated patients, three of the four who received SA healed their fistulas within two weeks. Only two of the other 13 medically treated patients (15 percent) healed their fistulas. Early surgery or the use of SA should be considered in the treatment of patients with low-output intestinal fistulas.
Nine patients with suspicious thyroid nodules were studied with positron emission tomography (PET) following the administration of [18F]-2-deoxy-2-fluoro-D-glucose (FDG) prior to surgical excision. Three patients were ultimately determined to have papillary carcinoma, four were shown to have follicular adenomas, and two were proven to have multinodular goiters with dominant nodules. All three malignancies and four of the six benign lesions were easily detected visually as areas of increased FDG uptake. While visual analysis alone did not discriminate between the benign and malignant lesions, all three malignancies had dose uptake ratios (DURs) for FDG in excess of 8.5 while the DURs for benign lesions ranged between 1.9 and 6.3. The mean FDG DUR for the three papillary carcinomas (10.9 +/- 3.9; mean +/- SD) was significantly greater (p = 0.0019) than that of the six benign lesions (3.2 +/- 1.7). There was no significant difference between the FDG DUR for the follicular adenomas and the dominant nodules of multinodular goiters. Further research is needed to confirm the usefulness of PET in the differential diagnosis of thyroid nodules, and, in particular, whether or not PET can discriminate between benign and malignant follicular neoplasms.
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.
