Abstract To investigate the safety and efficacy of laparoscopic splenectomy and portaazygous devascularization, we studied laparoscopic splenectomy and porto-azygos devascularization patients within the peri-operative period. Clinical data and curative effect are detailed alongside statistical analysis. The laparoscopic splenectomy and porto-azygos devascularization operation time was 2.56 + 0.62 hours. The intraoperative bleeding and anal exhaust time was 149.5 + 32.7ml 3.47 + 1.32 days, and the hospitalization time was 5.05 + 1.22 days. When the spleen volume was greater than or equal to 1.5 liters, the rate of open abdominal surgery increased significantly. After 1, 2, 3, and 4 years of follow-up, cumulative recurrence bleeding rates were 0, 5.20%, 9.98%, and 15.83%, respectively. Laparoscopic splenectomy and pericardial devascularization is safe, effective, and feasible, and it can be confirmed by enhanced spiral computed tomography (CT). Whether spleen volume greater than 1.5L is suited to laparoscopic surgery requires further research.

Idiopalhic thrombocytopenic purpura is an autoimmune disease in which macrophages of reticuloendothelial system, mainly in the spleen, remove platelets covered by autoantibodies from circulation. By removing the spleen 60-80% of patients are cured. Partial remission is achieved in 10-20% cases. Very few patients do not react on splenectomy. Recurrency of idiopathic thrombocytopenic purpura in a splenectomized patient after already achieved complete remission, may be caused by hypertrophy of one or more of the retained accessory spleens. We present 3 patients, 41, 23 and 44 year old, in whom splenectomy for HP had been performed 10, 3 and 11 years earlier. After full remission which lasted 10, 2.5 and 10.5 years a full recurrency of ITP took place with signs of severe thrombocytopenia and haemorrhagic syndrom. Using ultrasonography, computed tomography and scintigraphy accessory spleen/s, were discovered. By their removal, a full remission was achieved in all 3 patients, but full favorable effect appeared approximately three months after surgery during which period additional steroid therapy was necessary.

Abstract BACKGROUND: Sclerosing angiomatoid nodular transformation of the spleen is one kind of exceedingly rare benign lesions originated from spleen. The incidence and pathogen remain unclear partially due to its rarity and short history. Consequently, preoperative diagnosis become extremely perplex. Splenectomy is a predominated therapy approach as well as diagnosis method for sclerosing angiomatoid nodular transformation of the spleen. We reported a case underwent computed tomography scan, magnetic resonance imaging and ultrasonic scan preoperatively. Examinations conclusion highly suspected sclerosing angiomatoid nodular transformation of the spleen and was confirmed by pathology after laparoscopic splenectomy. We herein reviewed some literatures on imaging characters of to reveal the possibility of preoperative diagnosis when clinicians encounter and investigated whether laparoscopic splenectomy is an appropriate treatment.CASE PRESENTATION: A 50-year-old female was found with a low dense mass in the spleen by abdominal computed tomography incidentally without any positive symptom. Further enhanced computed tomography scan revealed the lesion with asynchronous enhancement and magnetic resonance imaging showed radio-like rift missing from central. Ultrasonic scan imaging presented hypoechoic gap in the center, pretty similar to magnetic resonance imaging. These radiology imaging features deduced to Sclerosing angiomatoid nodular transformation of the spleen. Laparoscopic splenectomy was performed successfully by our team and histopathological findings convinced the preoperative diagnosis. Gross inspection was coincident to the performance of magnetic resonance imaging.CONCLUSION: By comprehending imaging character profoundly, sclerosing angiomatoid nodular transformation of the spleen can be a differential diagnosis preoperatively when encounter lesion of spleen. We believe that laparoscopic splenectomy is a reliable and effective therapy option for such rare benign lesion of spleen without risk of recurrence.

Three Dimensional Images

We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As conventionally practiced in medical Computed Tomography (CT), radiologists produce maps of bone and tissue structure in several planar sections that reveal features with 1mm resolution and 1% contrast. Microtomography extends the capability of CT in several ways. First, the resolution which approaches one micron, is one thousand times higher than that of the medical CT. Second, our approach acquires and analyses the data in a panoramic imaging format that directly produces three-dimensional maps in a series of contiguous stacked planes. Typical maps available today consist of three hundred planar sections each containing 512x512 pixels. Finally, and perhaps of most import scientifically, microtomography using a synchrotron X-ray source, allows us to generate maps of individual element.
