PURPOSE: Multi-organ segmentation from CT images is an essential step for computer-aided diagnosis and surgery planning. However, manual delineation of the organs by radiologists is tedious, time-consuming and poorly reproducible. Therefore, we propose a fully automatic method for the segmentation of multiple organs from three-dimensional abdominal CT images. METHODS: The proposed method employs deep fully convolutional neural networks (CNNs) for organ detection and segmentation, which is further refined by a time-implicit multi-phase evolution method...

Cancer of uterine cervix is one of the most common malignancies in women. Metastatic recurrence of cervical cancer in spleen is rare, mostly seen in autopsies. Splenic metastasis from cervical cancer in a living patient without disseminated metastases is rarer. Here, we present the case of a lady aged 46 years with cervical cancer-squamous cell carcinoma-who had undergone radical hysterectomy and postoperative 50 Gy of intensity modulated radiation therapy in 25 fractions and 50 mg of weekly cisplatin for 6 weeks...

Introduction Splenectomy in children is nowadays widely performed by laparoscopy, the major risk being operative hemorrhage. We hereby compare the results of two different techniques of vascular control. Materials and Methods We retrospectively reviewed all patients undergoing a laparoscopic splenectomy (LS) for hematologic disease at a single institution from 2004 to 2013. LS was performed by a lateral approach. The 10-mm optic port was placed in the umbilicus and two 5-mm working ports were placed in the left lower quadrant and in the right upper quadrant near the midline...

Pancreatic cystic neoplasm(PCN) are common and increasingly detected in recent years including serous cystic neoplasms, mucinous cystic neoplasms, intraductal papillary mucinous neoplasms, solid pseudopapillary neoplasms and cystic pancreatic neuroendocrine tumors.Some of PCN have a low risk of malignancy while others have a high risk and need interventions, even in the same type of cystic neoplasms. The management of PCN requires risk stratification for malignant potential, and clinicians should have a systematic approach for establishing a diagnosis and determining which patients require surgical treatment...

Although the protective role of HO-1 induction in various forms of kidney disease is well established, mechanisms other than heme catabolism to biliverdin, bilirubin and carbon monoxide have recently been identified. Unraveling these mechanisms requires the generation of appropriate animal models. The present study describes the generation of a HO-1 deficient Hmox1 (-/-) rat model and characterizes its renal and extrarenal phenotype. Hmox1 (-/-) rats had growth retardation and splenomegaly compared to their Hmox1 (+/+) littermates...

Coccidiosis is regarded as the parasitic disease with the greatest economic impact on the poultry industry due to reduced performance and increased mortality. A study was conducted to investigate the effects of in ovo administration of probiotics on hatchability, performance, immune organ weights, and lesion scores in broiler chicks during a mixed Eimeria infection. At embryonic day 18, 210 eggs were injected with either sterile water or 1×10(6) cfu probiotic bacteria. On day 3 post-hatch, half of the chicks from each treatment group were challenged with a mixed inoculum of Eimeria acervulina, Eimeria maxima and Eimeria tenella...

It is unclear if persistent splenomegaly in the presence of a negative positron emission tomography (PET) scan before allogeneic hematopoietic cell transplantation (HCT) influences post-transplantation outcomes in patients with lymphoma. We retrospectively reviewed records of 152 patients who underwent allogeneic HCT for various lymphomas. Centralized review of pretransplantation computed tomography (CT) and PET images was performed. Spleen volume (SV) was measured using the freehand volume segmentation tool in AW Workstation software (General Electric, Waukesha, WI)...

3D Statistical Shape Models (3D-SSM) are widely used for medical image segmentation. However, during segmentation, they typically perform a very limited unidirectional search for suitable landmark positions in the image, relying on weak learners or use-case specific appearance models that solely take local image information into account. As a consequence, segmentation errors arise, and results in general depend on the accuracy of a previous model initialization. Furthermore, these methods become subject to a tedious and use-case dependent parameter tuning in order to obtain optimized results...

BACKGROUND: We describe our experience with what is, to our knowledge, the first case of robotic assisted ex vivo partial splenectomy with auto-transplantation for a benign non parasitic cyst. MATERIALS AND METHODS: The patient is a 32 year-old female with a giant, benign splenic cyst causing persistent abdominal pain. Preoperative imaging showed a cystic lesion measuring 8.3 × 7.6 cm, in the middle portion of the spleen. Due to the central location of the bulky lesion a partial splenectomy was not feasible...
