The authors presented a rare case of lymphatic angioma of mesentery of the small intestine. The patient underwent successful surgery. The study presents clinical symptoms, diagnostic and therapeutic problems in patients with lymphatic angiomas.

The aim of this work was to develop a simple and fast technique for spatial visualisation of colour cell specific markers in digital microscopy. Colour light microscopy images were transformed into their spatial representation by introducing image brightness as the third dimension. Based on spatial representation, the expression of selected colour specific markers was assessed by their surface, volume, area fraction and colour intensity. This technique was implemented for quantitative analysis of expression of PCNA, Ki67 and bcl-2 in chronic parathyroiditis cases. Comparing to standard, colour sampling techniques, the presented method based on spatial visualisation of the expression of markers in tissue sections, seems an effective and practical application in objective assessment of their distribution in the investigated material.

Pancreatic cancer is the thirteen leading most common malignancy, accounting for up to 2% of all malignancies. In majority of cases pancreatic cancer is diagnosed when local progression of the malignancy makes radical surgical treatment impossible. The extent of surgical treatment of tumors of the pancreatic head is planned on the basis of preoperative imaging studies and endoscopic studies and the final decision depends on intraoperative assessment of the lesion progression and results of cytological or histopathological examination of intraoperatively collected specimens. Fine needle aspiration biopsy (FNAB) is performed before possible resection of the tumor of the pancreatic head.The aim of the study was to compare results of FNAB with final histopathological assessment of collected specimen and survival of patients with negative cytological examination and patients in whom transduodenal fine needle aspiration biopsy confirmed the presence of cancer cells.Material and methods. This retrospective study involved 63 patients hospitalized due to tumor of the pancreatic head in Department of General, Gastroenterological and Endocrinological Surgery between 2000 and 2007. All patients underwent fine needle aspiration biopsy during the laparotomy. In some patients, an intraoperative decision was taken to proceed to core biopsy from suspected malignancy sites despite negative result of cytological examination. This analysis included only patients with evaluable material collected for cytological examination. Long-term results of treatment were obtained basing on clinical examination of patients who attended a follow-up visit and telephone survey conducted among patients and their families in the event of patients who did not attend a followup visit.Results. The longest overall survival of patients with positive cytological examination who underwent a palliative procedure was 10 months, while in patients who underwent radical treatment amounted to 2 years. Sensitivity of fine needle aspiration biopsy (FNAB) in our study was 85.7%Conclusions. FNAB is an indispensible part of diagnostic workup in the pancreatic cancer and cannot be omitted even in inoperable cancers confirmed by imaging studies. FNAB not only guides surgical treatment but also dictates adequate adjuvant and neoadjuvant systemic therapy - radio- and chemotherapy.

Inulin supplementation in rat model of pouchitis

Available data indicates potential effectiveness of prebiotic therapy in alleviating inflammation and prolonging the remission in inflammatory bowel disease. Documented successes of such therapies were the basis for this study. So far, there is no data related to the effectiveness of inulin application in symptomatic or severe pouchitis in humans or in animal model. The aim of the study was to determine the effect of inulin supplementation on the expression of intestinal inflammation and feeding efficiency in rats with induced pouchitis. Twenty-four Wistar rats were operated. After induction of pouchitis animals were randomly divided into control and supplementation groups receiving, respectively, semi-synthetic diet with or without inulin (in a lower (LD) or higher (HD) dose: 2.5 % or 5 % of total dietary content of mass) for a period of 6 weeks. Selected nutritional parameters were assessed throughout the study. Histopathological and immunohistochemical analysis of pouch mucosa specimens was also performed. The energy intake, weight gain, feeding efficiency, quality of stools were comparable in all studied groups. The intensity of inflammation (Moskovitz scale) and adaptive changes (Laumonier scale) did not differ between compared groups. The tissue expression of pro- and anti-inflammatory interleukins (IL-1α, IL-6, IL-10 and IL-12) was not different either. Inulin supplementation does not improve the quality of stools or the expression of intestinal inflammation in rats with induced pouchitis. It has no impact on the intensity of pouch adaptation or on feeding efficiency.

Restorative proctocolectomy is considered a surgical treatment of choice in ulcerative colitis (UC) and familial adenomatous polyposis (FAP).The aim of the study was to evaluate postoperative complications in patients who underwent surgery for familial adenomatous polyposis and ulcerative colitis, on the basis of a retrospective data analysis.Material and methods. Data of 138 patients after restorative proctocolectomy performed between 1985 and 2008 were collected at routine follow-up visits in 2004-2008. We evaluated the presence of pouchitis, the degree of ileal pouch mucosa atrophy, the presence of ileal pouch mucosal metaplasia, the presence of ileal pouch malignancies, the necessity for diverting ileostomy, the necessity for pouch resection, and severe faecal incontinence.Results. Complications were observed in 45 (32.4%) patients. Thirty-seven patients developed pouchitis (26.6%). Low-degree dysplasia, severe dysplasia or malignancies were observed in total in 20 patients (14.4%). Six (4.3%) operated patients developed other analysed complications.Conclusions. The most common complications of restorative proctocolectomy were dysplasia and pouchitis. The most common complication in patients operated for UC was pouchitis. The low observed incidence of intestinal pouchitis may be attributed to the implemented prophylaxis of inflammation. Dysplasia was the most common complication in patients undergoing proctocolectomy for FAP. Due to an increased risk of dysplastic lesions as compared with UC patients, careful endoscopic follow-up examinations are obligatory in this patient group. Other analysed complications were uncommon and were mostly a consequence of chronic pouchitis. Clinical symptoms of pouch-related problems were similar in both analysed groups.

Detection of mutations in families with a hereditary predisposition to colon cancer gives an opportunity to precisely define the high-risk group. 36 patients operated on for colon cancer, with familiar prevalence of this malignancy, were investigated using the DNA microarrays method with the potential detection of 170 mutations in MLH1, MSH2, MSH6, CHEK2, and NOD2 genes. In microarrays analysis of DNA in 9 patients (25% of the investigated group), 6 different mutations were found. The effectiveness of genetic screening using the microarray method is comparable to the effectiveness of other, much more expensive and time-consuming methods.
