OBJECTIVE: Distal pancreatectomy with splenectomy may be required for optimal cytoreductive surgery in patients with epithelial ovarian cancer (EOC) metastasized to splenic hilum. This study evaluates the morbidity and treatment outcomes of the uncommon procedure in the management of advanced or recurrent EOC. METHODS: This study recruited 18 patients who underwent distal pancreatectomy with splenectomy during cytoreductive surgery of EOC. Their clinicopathological characteristics and follow-up data were retrospectively analyzed. RESULTS: All tumors were confirmed as high-grade serous carcinomas. The median diameter of metastatic tumors located in splenic hilum was 3.5 cm (range, 1 to 10 cm). Optimal cytoreduction was achieved in all patients. Eight patients (44.4%) suffered from postoperative complications. The morbidity associated with distal pancreatectomy and splenectomy included pancreatic leakage (22.2%), encapsulated effusion in the left upper quadrant (11.1%), intra-abdominal infection (11.1%), pleural effusion with or without pulmonary atelectasis (11.1%), intestinal obstruction (5.6%), pneumonia (5.6%), postoperative hemorrhage (5.6%), and pancreatic pseudocyst (5.6%). There was no perioperative mortality. The majority of complications were treated successfully with conservative management. During the median follow-up duration of 25 months, nine patients experienced recurrence, and three patients died of the disease. The 2-year progression-free survival and overall survival were 40.2% and 84.8%, respectively. CONCLUSION: The inclusion of distal pancreatectomy with splenectomy as part of cytoreduction for the management of ovarian cancer was associated with high morbidity; however, the majority of complications could be managed with conservative therapy.

Sclerosing angiomatoid nodular transformation (SANT) of the spleen, a newly defined primary lesion of the spleen, is very rare. Immunohistochemistry is the only way to confirm the diagnosis of SANT. We present the clinical characteristics and postoperative outcomes of five SANT cases that underwent splenectomy from January 2007 to October 2010. Although SANT had specific imaging findings, differential diagnosis from other splenic tuomrs or malignant lesions preoperatively was difficult. The hand-assisted laparoscopic splenectomy was a useful and effective technique for the management and postoperative diagnosis of SANT. All SANT patients had good prognosis without recurrence after splenectomy.

Portal annular pancreas is one of the pancreatic fusion anomalies in which the uncinate process of the pancreas extends to fuse with the dorsal pancreas by encircling the portal vein or superior mesenteric vein. We report two consecutive patients with portal annular pancreas. The first case is a 71-year-old male patient who underwent a pancreaticoduodenectomy for intraductal papillary mucinous neoplasm in the head of pancreas. His preoperative computed tomography scan showed the suprasplenic type portal annular pancreas. The second case is a 74-year-old female patient who underwent a laparoscopic anterior radical antegrade modular pancreatosplenectomy (RAMPS) for pancreatic body cancer. In operative finding, portal confluence (superior mesenteric vein-splenic vein-portal vein) was encased with the uncinate process of pancreas in both cases. Therefore, they required pancreatic division at the pancreatic neck portion twice. During the postoperative period, grade B and A, respectively, postoperative pancreatic fistulas occurred and were controlled by conservative management. Surgeons need to know about this rare pancreatic condition prior to surgical intervention to avoid complications, and to provide patients with well-designed, case-specific pancreatic surgery.

OBJECTIVETo study the clinicopathologic features, differential diagnosis and pathogenesis of sclerosing angiomatoid nodular transformation of spleen.

METHODSTen cases of sclerosing angiomatoid nodular transformation of spleen were retrieved from the archival file. Histochemical and immunohistochemical (EnVision method) studies were performed. Ultrastructural findings were also available in one of them.

RESULTSSclerosing angiomatoid nodular transformation was characterized by micronodular appearance of vascular spaces lined by plump endothelial cells with interspersed ovoid spindle cells. Immunohistochemical study showed that the endothelial cells of vessels in the angiomatoid nodules had various expressions of immunologic phenotypes and could be mainly classified into 3 types: CD34(+)/CD31(+)/CD8⁻ endothelial cells of the capillaries, CD8(+)/CD31(+)/CD34⁻ lining cells of the sinusoids and CD31(+)/CD8⁻/CD34⁻ endothelial cells of the small veins. Collagen network and dilated lymphatic sinuses were evident under transmission electron microscope.

CONCLUSIONSSclerosing angiomatoid nodular transformation of spleen is a rare benign entity. It may represent a reactive condition and bears some relationship with splenic angioma. It needs to be distinguished from borderline or malignant vascular tumors of spleen.
