Background Whereas specimen radiography (SR) is an established strategy for intraoperative resection margin analysis during breast-conserving surgery for nonpalpable lesions, the use of frozen section analysis (FSA) is still a matter of debate. Methods A retrospective review was conducted of 115 consecutive operations in which the two objectives sought were the excision of nonpalpable malignant lesions and breast conservation. Breast surgery was performed in the Gynecology and the Surgery Departments at the Basel University Hospital Breast Center. Whereas one department preferably uses SR for intraoperative margin assessments of lesions involving ductal carcinoma in situ (DCIS) or atypical ductal hyperplasia, the other uses FSA to increase the rate of complete removal of these lesions with a single procedure. The respective accuracy and therapeutic impact of these two techniques are compared here. Results Intraoperative resection margin assessments were performed with FSA in 80 and SR in 35 of a total of 115 operations performed on 111 patients with pTis, pT1, or pT2 nonpalpable breast cancer. FSA diagnostic accuracy, sensitivity, and specificity were 83.8%, 80.0%, and 87.5%, respectively, compared to 60%, 60%, and 60%, respectively, for SR. FSA tended to have a stronger therapeutic impact than SR in terms of the number of patients in whom initially positive margins were rendered margin-negative thanks to intraoperative analysis and immediate reexcision or mastectomy (27.5% vs. 14.3%; p = 0.124). More importantly, significantly fewer secondary reexcisions were performed in the FSA series than in the SR series (12.5% vs. 37.1%; p = 0.002). Finally, the intraoperative detection of invasive cancer with FSA led to a significantly lower number of secondary procedures for axillary lymph node staging (5% vs. 25.7%; p = 0.001). Conclusions The present results suggest that FSA may be more accurate than SR for analyzing intraoperative resection margins during breast-conserving surgery for nonpalpable lesions.
We report a case of a 63-years-old woman with a ten years history of increasing abdominal girth with associated abdominal pain. Abdomino-pelvic ultrasound and computed tomography scan revealed a large left ovarian cyst. The patient underwent laparotomy, resection of ovarian cyst and hysterectomy with bilateral ovarian resection. The removed huge mucinous cystadenoma, weighed 27 kg. Her post-operative course was unremarkable.
Postoperative delirium, morbidity, and mortality in our elderly patients with secondary perionitis of colorectal origin is described. This is a chart-based retrospective analysis of 63 patients who were operated on at the University Hospital Basel from April 2001 to May 2004. Postoperative delirium occurred in 33%. Overall morbidity was 71.4%. Surgery-related morbidity was 43.4%. Mortality was 14.4%. There was no statistical significance between delirium, morbidity and mortality (P = 0.279 and P = 0.364). There was no statistically significant correlation between the analyzed scores (American Society of Anesthesiologists classification, Mannheimer Peritonitis Index, Acute Physiology and Chronic Health Evaluation score II, physiological and operative surgical severity and enumeration of morbidity and mortality score' or short 'cr-POSSUM') and postoperative delirium, morbidity or mortality. Postoperative delirium occurred in one-third of the patients, who seem to have a trend to higher morbidity. Even if the different scores already had proven to be predictive in terms of morbidity and mortality, they do not help the risk stratification of postoperative delirium, morbidity, or mortality in our collective population.
We report the first documented case of distal thromboembolism originating from an abdominal aortic aneurysm (AAA) after a blunt trauma. A 72-year-old man with a known 6.2 cm AAA was brought to our emergency department with signs of bilateral acute limb ischemia developing immediately after an accidental fall. The occlusion was confirmed at computed tomographic angiography, and the aneurysm showed a fragmentated/ulcerated mural thrombus, morphologically different as compared to the previous computed tomography (CT). A thromboembolectomy was performed and, after treatment of the ischemic complications, the aneurysm was repaired by open surgery. Embolization from aneurysms in the setting of a trauma is a challenge for the vascular surgeon, also because of its rare occurrence. We describe the management and discuss the operative strategy we opted for in this patient.
