[Usefullness of scintigraphy with somatostatin analogues in the imaging of insulinoma of the pancreas].

We present a case of a 74-years-old female with insulinoma of the pancreas. Neuroglycopenic symptoms (Whipple's triad) and a positive fast test established the diagnosis. The fast was terminated after 5 hours and 40 minutes because of neuroglycopenic symptoms with the serum glucose and insulin levels of 40 mg/dl and 34,01 microU/ml respectively. The tumor was invisible in ultrasound, abdominal CT scan and MRL The only means that enabled preoperative visualization was 111-Indium labeled octreotide scintigraphy (OctreoScan). Laparotomy was performed, and a tumor was disclosed in intraoperative ultrasonography within the head of the pancreas. The tumor of 37 mm diameter was excised. Histopatological examination revealed benign insulinoma. After surgery the symptoms alleviated completely. The patient with proper glucose levels and insulin concentration of 3,04 microU/ml was discharged in good health. This case confirms high usefulness of preoperative OctreoScan and intraoperative ultrasonography in the approach to a patient with insulinoma.

[Adrenal tumours in a selected 10-years surgical material].

UNLABELLED: The aim of the study was to analyze the number and proportions of different adrenal tumours resected during the last 10 years in our centre. Besides, we seek correlations between the size of tumours and the age and body mass indexes (BMI) of the examined patients. MATERIAL AND METHODS: The tumours where measured on CT and MRI before surgery, and on pathological examination after resection. The examined group consisted of 69 patients, 22 males and 47 females, mean age 50.51 +/- 12.26 yrs. In 45 (65.22%) cases the right adrenal was affected, in 21 (30.43%)--the left, in 3 (4.35%)--both. RESULTS: 12 adrenocortical cancers, 20 phaeochromocytomas, 9 cortisol-secreting adenomas, 4 aldosteronomas, 18 hormonally inactive adenomas, 6 miscellaneous tumours were found. Malignant tumours where significantly larger than benign (12.20 +/- 6.81 vs 6.71 +/- 5.62 cm, p < 0.005). We observed no correlation between the age and preoperative tumor size (p = 0.1756), between the age and pathological tumor size (p = 0.3601), and between BMI and the preoperative and histopathologic size (p = 0.4204, and p = 0.6478, respectively). CONCLUSIONS: The most common tumour was phaeochromocytoma. Most tumours where found in the right adrenal. The malignant tumours where larger than benign ones. No correlations between age and BMI, and tumour size where demonstrated.

Effects of gastrectomy or colectomy on liver metabolism and liver morphology in an experimental rat model.

BACKGROUND: It is sometimes necessary to translocate part of the gastrointestinal tract into the site of the organ earlier resected. This occurs after total esophageal, stomach or colon resection, which can lead to disturbances in the anatomical and functional balance of the gastrointestinal tract and the body as a whole. The aim of this study was to evaluate the effects of different resective surgical procedures performed on the proximal and distal GI tract in terms of total body weight, selected liver function tests, and ultrastructural changes in the liver in laboratory rats. MATERIAL/METHODS: The total of 57 resective procedures consisted of 31 total gastric and 26 total colon resections. The control group consisted of 12 animals on which only laparotomy was performed. Body weight, stool character, and the general condition of the animals were evaluated from the time of the operation. Twenty-six blood samples were collected for analysis of hemoglobin, total plasma protein, and liver aminotransferases levels. Thirty liver tissue samples from the 3 groups were taken and examined. RESULTS: We observed statistically significant decreases in total body weight, hemoglobin, and total plasma protein levels in the group where reconstructive procedures following gastrectomy were performed. In the group in which reconstructive procedures followed colectomy, a statistically significant decrease in total body weight was observed. Aminotransferase level changes were neither characteristic nor significantly different in any of the three groups involved in the investigation. CONCLUSIONS: Abnormalities of liver structure were observed at the ultrastructural level. Any correlation between these changes, general condition, and selected biochemical parameters requires further controlled clinical and experimental studies.

Diagnostic difficulties in pouchitis--experience from a single institution.

The aim of the study was to analyze the clinical, endoscopic and histological signs of pouchitis in patients operated on because of ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Between 1984 and 2002, the Department of Surgery carried out 218 restorative proctocolectomies in patients with UC and 120 in FAP patients. The follow-up to assess the intensity of inflammatory changes included 110 patients: 72 UC and 38 FAP. During the endoscopic examination, samples were taken for routine histological examinations. The histological assessment was based on the so-called Moskwitz's Histological System. Acute pouchitis is diagnosed if the score is > or =4, and chronic condition--if the score is > or =4. We used a modified PDAI scale to analyze the symptoms, taking into account the microscopically detectable histological features of chronic pouchitis. The clinical symptoms of pouchitis were revealed in 28 patients (25.5%), endoscopic symptoms in 36 patients (32.7%), and histological parameters in 48 patients (28-58.3% with > or =4 score of acute pouchitis and 20-41.7% with > or =4 score of chronic pouchitis). The signs of acute and chronic pouchitis were evident in endoscopy and histology, with no clinical features observed in many cases. Patients with symptoms of chronic pouchitis require a continuous follow-up.

[Primary clear cell carcinoma of the thyroid--case report].

UNLABELLED: We present a case of a 59-year old woman in whom incidentally a thyroid nodule of 10 mm diameter was discovered. A fine needle aspiration biopsy was performed and it revealed follicular tumour. The patient was referred to surgery and she had a subtotal thyreoidectomy performed with a part of the left lobe spared. The histopathological examination of the nodule led to a different diagnosis. The diagnosis was clear cell carcinoma in the thyroid, probably metastatic, the most probable primary site being the kidney. A computed tomography scan of the kidneys and abdomen was performed but it revealed no changes. The patient has been seen for a year in follow-up, with CT scans performed every six months that revealed no changes. The patient has been in good condition during the whole period of observation. CONCLUSIONS: We describe an extremely rare case of a primary thyroid clear cell carcinoma.

[Insulinoma of the pancreas--difficulties with imaging].

We present a case of 29-year old man in whom despite the lack of finding tumor in USG and CT surgical intervention was performed and insulinoma of the pancreas was excised. Insulinoma was diagnosed on the basis of clinical picture (Whipple's triade) that was reassured by positive fast test. The fast was terminated at 11 and half hours because of neuroglycopenic symptoms with serum glucose and insulin levels 2.0 mmol/l (36 mg/dl) and 11.07 microU/ml respectively, which established the diagnosis. Laparotomy was performed, during which the tumor was palpated and seen in ultrasonography in the head of pancreas. The tumor of 12 mm diameter was excised. Histopathological examination revealed benign insulinoma. After surgery the symptoms alleviated completely. The patient with proper glucose levels was discharged in good health. The case supports high usefulness of intraoperative ultrasonography and surgeon's palpation.
