Gastric lipoma is a rare benign tumor. The symptoms are correlated with the size and the dimensions of neoplasm. It can be the cause of bleeding, gastroduodenal intussusception and intestinal obstruction, as in case reported and surgically treated. The Authors make a literature review to define the better diagnostic and surgical approach.
Intra- and early (first week) post-operative haemorrhages are the most common complications in stapled hemorrhoidectomy PPH (Procedure for Prolapse and Hemorrhoids) and in circumferential resection of the rectal prolapse STARR (Stapled Trans Anal Rectal Resection). Performing PPH and STARR we employed a gelatin based haemostatic sealant with thrombin component (FloSeal) to control intra-operative bleeding and to reduce post-operative bleeding avoiding haemostatic stitches on suture line. We report the preliminary results on 197 PPH and 64 STARR; 44 PPH (22.4%) and 27 STARR (42.2%) were treated by FloSeal. No major post-operative bleeding was observed in all patients treated by FloSeal, compared to 1.3% and 2.7% of hemorrhage respectively in PPH and STARR patients treated without sealant. Post-operative pain was less severe in patients treated by FloSeal, without a difference statistically significant. The data are preliminary and must be confirmed in prospective randomized trials in larger series.

A case of myofibroblastic pseudosarcomatous tumor of the bladder occurred in a patient previously submitted to TURB is reported. Aim of this investigation is to demonstrate, on the basis of the literature, the importance of histopathology in the diagnosis of bladder pseudosarcoma, since endoscopical and radiological methods can erroneously show a neoplasm. A 65-year-old male patient with hematuria, submitted to ultrasonography and cystoscopy, revealed a bladder superficial papillary formation. A TURB was performed and the histological study showed a superficial bladder cancer (T1-G1-2). After a second hematuria episode with stranguria a new bladder formation was diagnosed and resected; the histological study revealed a bladder pseudosarcoma. The absolute benignity of the lesion and the slight difference in the symptomatology between urothelial carcinoma and pseudosarcoma are underlined. Furthermore, the importance of histopathology to obtain an accurate diagnosis is stressed. The difficulty of a preoperative diagnosis without histopathological examination is pointed out.
Historically, carcinoids have long been known as a morphologically distinct class of rare intestinal tumors which behave less aggressively than the more common intestinal adenocarcinomas. In recent decades refined methods in pathology improved our knowledge on the diffuse neuroendocrine system, leading to some confusion in classification and nomenclature of carcinoids. The World Health Organization (WHO) classification of endocrine tumors has cleared the definition of carcinoids. The Authors report on 7 cases of midgut carcinoid tumors and 1 case of carcinoid syndrome focusing on the newer approaches to the diagnosis, localization, and role of surgery and peptide therapy.
The Authors report on a case of blind-ending ureter. A young woman (29 years old) underwent surgery because of recurrent urinary tract infections and left loin pain. The operation consisted in a radical resection of the blind branch together with Coen's operation for the coexistence of vesicoureteral reflux. Authors' goal was to review the international Literature on this rare pathology pointing out their opinion on the existing terminology which is still far from being clear and definite.
Nutritional support for acute pancreatitis is a matter of debate, clear guidelines based on objective data do not exist. We report our experience in patients with severe disease. Parenteral nutrition appears to be a safe initial therapy, but the enteral route has many practical and theoretical advantages and should be started as soon as possible.
Iatrogenic bile duct injury during cholecystectomy is the most serious complication of this surgical procedure. Initial reports suggest that this complication is particularly troublesome during laparoscopic cholecystectomy. Proper identification of the biliary anatomy in the subhepatic region is the only way to avoid this catastrophe. The potential benefits of a simple, reliable method for intraoperative delineation of biliary anatomy are self-evident. In this experimental study on rabbits, we show how the simple i.v. injection of a fluorescent bile salt, cholyl-lysyl-fluorescein, enables the surgeon to visualize the entire biliary tree in anatomic detail.
The authors briefly report their experience regarding the opportunities offered by the use of current ultrasound methods in carotid surgery. They describe: a system for the quantification of athcromasic plaque used to monitor non-operated patients over time; ultrasound methods used to analyse the carotid wall to establish whether it can be utilised as an index of vascular aggression in hypertension, diabetes and atherosclerosis; the use of transcranial Doppler; criteria for the definition of high risk plaque; the applications of eco-color Doppler. The paper also illustrates a new pathology identified by the authors, defined as primary intimal fibrous hyperplasia, and the evolution of the carotid wall after endarterectomy. The structural characteristics of primary hyperplasia can only be shown using ultrasound given that arteriography cannot distinguish it from atheromatic stenosis. After endarterectomy the carotid wall is subject to hematic and hemodynamic stimuli which determine the type of evolution of the wall itself. The authors therefore examine the myointimal reaction, myointimal hyperplasia, early restenosis and late restenosis as different facets of the same phenomenon.
In this study a good sensibility of ultrasound in identifying ductal disease was demonstrated. We evaluated the relationship between nipple discharge and ductal ectasia and the importance of the ectasia in maintaining nipple discharge. From our data the hypothesis of a possible role of oestroprogestinic hormones in the genesis or maintaining of ductal ectasia emerged.

Primary lymphoma of the lung is a rare pathological condition arising from mucosa-associated lymphoid tissue (MALT). The lack of specific symptoms and the related diagnostic problems induced the authors to report a clinical case recently observed. Therefore, some histopathologic characteristics useful for a correct differential diagnosis with the pseudolymphoma of the lung and the interstitial lymphocyte pneumonia are analysed.
Hyperparathyroidism due to parathyroid carcinoma is rare. The natural history of this neoplastic disease is poorly understood for the extremely small number of cases reported in literature. The Authors observed three cases and discuss the clinical features illustrating how to recognize and treat this neoplasia.
