The present study was undertaken to evaluate the impact of surgical exploration on survival of patients with potentially resectable pancreatic cancer, who intraoperatively were found to have unresectable disease. Methods: Patients with pancreatic adenocarcinoma undergoing surgical exploration, without tumor resection, at our institution between 2009 and 2014, were selected and case-matched to patients who underwent primary palliative treatment. Results: A total of 116 patients were included. The surgical exploration group (n = 29) had significantly lower CRP levels at the time of diagnosis compared to the palliative controls (n = 87), 4 mg/L vs 12 mg/L;p = 0.004. The percentage of patients who received palliative chemotherapy was comparable between groups, but the time until start of chemotherapy was significantly longer in the surgical exploration group, 2 months vs 1 months;p Conclusion: In this case-control study, we could not detect any survival disadvantage due to surgical exploration in the setting of unresectable pancreatic cancer. Surgical exploration was associated with delayed start of palliative chemotherapy, but the percentage of patients who ultimately received chemotherapy was comparable to patients undergoing primary palliative treatment.展开更多

If in closed trauma, a morphological assessment of the lesion is usually necessary before treatment, in open trauma otherwise, namely in the case of testicular evisceration, surgical exploration is the rule. Objective: To present the management of open scrotal trauma. Case Presentation: These were two adults aged 42 and 63, admitted for post-traumatic testicular evisceration. One of the patients presented with signs of infection due to a diagnosis delay. Management consisted on surgical exploration, with scrotal debridement and testicular reintegration. The evolution was favourable. Conclusion: Open scrotal trauma is a rare lesion that can cause testicular evisceration. It requires surgical exploration, which should be systematic.展开更多

Patient and Methods: Thirty patients suspected to have small bowel neaoplasms were examined with 64 MDCT and underwent surgical exploration. Result: Contrast enhanced MDCT enterography easily diagnosed twenty patients with small intestinal neoplasms which were confirmed with surgical exploration and histopathological results. Conclusions: Our study has been proved that MDCT can be used as a front-line imaging modality for detection of small bowel neoplasms, regarding its ability to show intraluminal, mural and extraintestinal lesions with their characteristic density and features to successfully differentiate between the different neoplasms and sometimes stage them. However, operative exploration with curative resection or biopsy is still the confirmatory diagnostic method.展开更多

Operative exploration revealed anterior communicating aneurysms in these patients. It is thought possible that these patients harbored aneurysms which failed to exhibit on angiograms due to temporary thrombosis or development of abnormal cerebral vessels. CT scanning was important for diagnosis of these patients.展开更多
