Preoperative duplex vein mapping (DVM) reduces costs in patients undergoing infrainguinal bypass surgery: results of a prospective randomised study.

OBJECTIVES: Surgical site infections (SSIs) after bypass procedures provoke major costs. The aim of this prospective randomised trial was to assess if preoperative duplex vein mapping (DVM) reduces costs generated by SSI. MATERIALS/METHODS: Patients undergoing primary infrainguinal bypass were randomised to DVM of the ipsilateral greater saphenous vein (group A) or none (group B). Costs were calculated by the hospital's accounting department. RESULTS: From December 2009 to April 2011, 130 patients (65 each group) were enrolled. Both cohorts were equal regarding demographics, risk factors and costs for primary bypass surgery, respectively. SSIs were classified minor (A: n = 13 vs. B: n = 13, P = n.s.) and major (A: n = 1 vs. B: n = 12, P = .0154). Preoperative DVM was the only significant factor to prevent major SSI (P = .011). Theatre costs for SSI: A: 537 € versus B 6553 € (P = .16). Recovery room/intensive care unit (ICU) costs for SSI: A: 0 € versus B: 8016 € (P = .22). Surgical ward costs for SSI: A: 2823 € versus B: 22 386 € (P = .011). Costs for outpatient visits due to SSI: A: 6265 € versus B: 12 831 € (P = .67). Total costs of patients without SSI: 8177 € versus major SSI: 10 963 € (P < .001). CONCLUSION: DVM significantly reduces costs generated by re-admission in patients suffering from major SSI.

Clinical value of cervical mediastinoscopy in the staging of bronchial carcinoma.

Whether mediastinoscopy is indicated in the preoperative staging of bronchogenic carcinoma is still a controversial issue. It may be performed routinely (to exclude locally inoperable patients from surgery), selectively, or it may be regarded as superfluous (in centers which prefer an extended lympho adenectomy at the time of thoracotomy). We regard mediastinoscopy as indicated for the following purposes: 1) staging of NSCLC and SCLC; 2) diagnostic (mediastinal masses or lung tumors without previous histology); 3) restaging after primary chemotherapy; 4) assessment of prognosis in patients with borderline operability. The indication for 224 mediastinoscopies performed at our institution in the period from September 1991 through March 1999 was mainly for staging (59.2%) or diagnostic (30.6%). Eight (5.4%) patients underwent mediastinoscopy for the assessment of operability, and 7 (4.8%) after primary chemotherapy for the restaging of loco-regionally advanced lung cancer. Sensitivity and specificity rates were 87% and 100%, respectively, with an accuracy of 93% for the mediastinoscopy performed for the staging of lung cancer at all stages. If we consider the N2 tumors (42 cases) alone, the sensitivity was 76.7% and the specificity 100%, with an accuracy of 83.3%. Overall positive and negative predictive value resulted 100% and 87%, respectively, according to the data reported in literature. Our data confirm the role of mediastinoscopy as the gold standard for regional staging of lung cancer.

[Gastric neoplasia in pregnancy: report of a case]. / Neoplasia gastrica in gravidanza: case report.

CASE REPORT: Gastric cancer in a 29 years old pregnant woman. A total of 109 cases were collected in the whole from 1916 to 1988; to these, we add one new case of a 29 years old pregnant woman observed in 1993 in Verona University Surgical Sciences Department. DISCUSSION: Cancer of the digestive tract during pregnancy is really rare and has poor prognosis. The diagnosis during pregnancy is difficult because the symptoms are frequently masked by factors related to the normal first trimester in pregnancy. X-ray are often restricted. Gastroendoscopy is applied to pregnant women only when evident symptoms are present such as: severe anemia, jaundice and weight loss. The incidence of inoperable cases is elevated such as the mortality in the operated cases. The whole survival rate after three years is 21%. CONCLUSION: Gastric cancer in pregnancy has a poor prognosis. The possible reasons are: delayed detection, low differentiation degree, restricted therapeutic approach because of pregnancy, personal factors as the patients' desire for a child, religious, ethical considerations.
