Selected parameters of nutritional status in patients with pancreatic head cancer - own experience.

Introduction: Around 200,000 new cases of pancreatic cancer are diagnosed yearly worldwide. It is the fourth most common cause of cancer deaths. Pancreatic cancer has a high mortality rate due to unspecific symptoms being responsible for late diagnosis. Aim: In this study, the authors analysed selected nutritional parameters and the severity of anaemia in patients diagnosed with pancreatic head cancer. Material and methods: Data were collected upon admission to the 2nd Clinical Department of General, Gastrointestinal, and Oncological Surgery in the University Clinical Hospital in Bialystok, Poland and retrospectively with the help of correctly collected anamnesis. Results: It has been shown that most patients with pancreatic cancer are malnourished at the time of diagnosis. Body mass index (BMI) is the least valuable parameter primarily. Weight loss has been determined to be the most accurate predictor of the patient's metabolic status, although it should never be the only parameter. Although these factors do not suggest an inflammatory process, serum protein levels and albumin concentration should be considered. Conclusions: When assessing the nutritional status of patients with pancreatic cancer, many predictive factors should be considered. BMI seems to be the least accurate parameter for assessing nutritional status in patients diagnosed with cancer. However, when combined with weight loss and serum albumin levels, it can be quite useful as a prognostic factor.

Phase Angle and Postoperative Complications in a Model of Immunonutrition in Patients with Pancreatic Cancer.

BACKGROUND: The aim of this study was to determine the influence of our own model of immunonutrition on phase angle and postoperative complications. Our goal was to establish modern prehabilitation procedures for patients operated on for pancreatic cancer. METHODS: Patients with pancreatic cancer who qualified for surgical treatment were divided into two groups. Group I (20 patients; 12 with pancreatic head cancer, 8 with pancreatic tail/body cancer) was given immunonutrition (Impact Oral 3× a day, 237 mL, for 5 days before surgery, and after surgery for an average of 3.5 days). Group II (20 patients; 12 with pancreatic head cancer, 8 with pancreatic tail/body cancer) did not receive immunonutrition. Body weight, body mass index and phase angle were assessed on admission to the hospital, after preoperative immunonutrition, on the third and eighth postoperative days. C-reactive protein and Interleukin-1 α were measured on admission to the hospital, after preoperative immunonutrition, on the eighth postoperative day. Postsurgical complications were assessed via Clavien-Dindo classification. RESULTS: On admission to the hospital, the phase angle was 5.0° (4.70-5.85) in Group I and 5.1° (5.00-6.25) in Group II. After 5 days of using preoperative immunonutrition, it increased statistically significantly (p < 0.02) to 5.35°. In Group I, on the third day after surgery, it decreased statistically significantly (p < 0.001) to 4.65°, and then, increased to 4.85° on the eighth day. In Group II, statistically significant decreases in the phase angle were observed on the third (4.5°; p < 0.002) and eighth (4.55°; p < 0.008) days after surgery. A statistically significant increase in CRP (86.6 mg/dL; p < 0.02) and IL-1α (18.5 pg/mL; p < 0.03) levels was observed on the eighth day after surgery in this group. In Group I, a statistically significant negative correlation (R -0.501106; p < 0.002) of the phase angle after 5 days of preoperative immunonutrition with postoperative complications was observed. CONCLUSIONS: This study used our own model of immunonutrition in patients undergoing surgery for pancreatic cancer. The applied model of perioperative IN improved the postoperative course of patients operated on due to pancreatic cancer. Fewer complications were observed in patients in the group receiving IN. Also, the PA value increased after the 5-day preoperative IN, and the use of perioperative IN improved the PA value on the eighth postoperative day compared to the group that did not receive IN. On this day, an increase in inflammatory parameters was also observed in the group that did not receive IN. In addition, PA correlated negatively with complications. The PA can be a useful tool to assess the effectiveness of the applied IN, and thus, to predict the occurrence of postoperative complications. Therefore, there is a further need for studies on larger groups of patients.

Preoperative Glutamine Supplementation in Gastric Cancer-Thrombocyte Phagocytic Activity and Early Postoperative Outcomes.

BACKGROUND: The aim of this study was to determine the phagocytic activity of thrombocytes in patients with gastric cancer and to assess the effect of oral and parenteral preoperative glutamine-based immunonutrition on nutritional status, thrombocyte phagocytic activity, and early postoperative outcomes. METHODS: Patients suffering from invasive gastric cancer had been treated with preoperative immunonutrition with glutamine, and they were compared to patients without nutritional treatment. Nutritional status, percentage of weight loss, and BMI were assessed. Levels of total protein, albumin, cholesterol, triglycerides, platelets, and their phagocytic ability were measured twice. Postsurgical complications were assessed via the Clavien-Dindo classification. RESULTS: Group I consisted of 20 patients with an oral glutamine-10 g daily. Group II had 38 patients who received intravenous glutamine, 1.5 mL per kg body weight of Dipeptiven. Group III consisted of 25 patients who did not receive preoperative immunonutrition. In total, 47% of patients in Group I, 54% of patients in Group II, and 33% of patients in Group III were malnourished. In Group I, the percentage of phagocytizing platelet (%PhP) was 1.1 preoperatively and 1.2 postoperatively. The phagocytic index (PhI) was 1.0 and 1.1. In Group II, %PhP was 1.1 and 1.2 and PhI was 1.0 and 1.1. In Group III, the %PhP was 1.0 and 1.2 and PhI was 1.0 and 1.1. An increase in triglyceride level was observed in both immunonutrition groups. There was a decline in total protein and albumin level in Group II. In Group III, there was a decline in total protein, albumin, and cholesterol level. The total platelet count and PhI were increased in both immunonutrition groups. There was also a rise in %PhP in Group II. In Group III, there was a rise in blood platelet level, %PhP, and PhI. The complication rates were 53% in Group I, 29% in Group II, and 40% in Group III. CONCLUSIONS: In invasive gastric cancer, laboratory nutritional parameters are significantly reduced, causing malnutrition in 44.7% of patients. Oral glutamine supplementation inhibited the postoperative decline in protein metabolism parameters; however, this did not affect the reduction in the percentage of postoperative complications. Glutamine used preoperatively significantly reduced the percentage of serious surgical complications, regardless of the way it was supplemented. Patients with invasive gastric cancer have a significant decrease in platelet phagocytic activity. The administered preoperative parenteral nutrition and the surgical procedure itself influenced the improvement of the phagocytic activity of blood platelets. Glutamine did not have this effect, regardless of the route of administration.

Laparoscopic organ-sparing surgery for cystic lesions of the spleen - own observations.

<b>Introduction:</b> Splenic cysts are quite rare. In this publication, authors focus on presenting their own observations related to the management of patients with such lesions. </br></br> <b> Aim:</b> To evaluate the effectiveness of laparoscopic procedures in the case of patients with splenic cysts. </br></br> <b>Material and methods:</b> The study included patients treated surgically for cystic lesions located in the spleen at the 2^nd Department of General, Gastroenterological and Oncological Surgery of the Medical University of Bialystok over the years 2017-01.2020. </br></br> <b>Results:</b> All patients were referred for elective excision of the spleen lesion (the size of the lesions ranged from 7 to 15 cm - based on CT examination). In all cases, excision of the anterior wall of the cyst was performed with the help of advanced surgical tools. The duration of the procedure ranged between 65 and 100 minutes. No significant blood loss was observed. No postoperative complications were found. </br></br> <b>Conclusions:</b> In conclusion, sparing laparoscopic surgery for cystic lesions of the spleen seem to be safe and rarely associated with complications or relapses. Extending the scope of the procedure to total splenectomy should also not pose a major problem.

Foods for Special Medical Purposes in Home Enteral Nutrition-Clinical Practice Experience. Multicenter Study.

Background: Enteral nutrition (EN) with foods for special medical purposes (FSMP) is recommended for most patients on home enteral nutrition (HEN). Although there are disease-specific guidelines for energy, protein, and micronutrient provision, only a few studies are showing real-life experience in the long-term use of FSMP. Methods: In a multicenter study, the influence of the FSMP composition and administration technique (bolus vs. continuous) on protein and energy provision in HEN was analyzed. Provision of vitamins and minerals was compared to recommended daily allowance (RDA) and upper tolerable limit (UL). Results: Approximately, 772 patients on HEN, mostly (88.6%) with oncological and neurological diseases, were enrolled. The patients on standard FSMP received less protein and energy than those on hypercaloric and protein enriched despite receiving higher volumes of EN (p < 0.05). No differences were observed in jejunal feeding with oligomeric vs. polymeric FSMP in terms of energy, protein, and volume. Continuous gastric feeding provided more protein, energy, and volume vs. bolus feeding (p < 0.05). Significant number of patients received less than 100% RDA of vitamin D (50.5%), vitamin B3 (49%), vitamin K (21.8%), vitamin B5 (64.3%), vitamin B9 (60%). Majority of the patients received less than 100% RDA of sodium (80.2%), potassium (99%), chloride (98%), calcium (67%), magnesium (87%), fluoride (99%), and iodine (43%). Approximately, 43.63% of cancer and 49.9% of neurological patients received less than 1 g/kg/day of protein and 51.7% of cancer and 55.5% of neurological patients received less than 25 kcal/kg/day. Conclusion: Awareness of the available compositions of FSMP and advantageous profiles of specific diets may lead to the implementation of recommendations for EN. HEN professionals need to analyze all the patient's needs and requirements to provide more tailored matching of nutritional support.

Body composition of patients suffering from pancreatic cancer.

Pancreatic cancer, despite significant progress in diagnosis and treatment still has poor prognosis. Surgical treatment remains the only cure option. Unfortunately, the percentage of patients in whom radical tumor removal is possible is less than 20%. Resection procedures are burdened with a high degree of difficulty, as well as a high complication rate. One of the important factors contributing to the high morbidity of the perioperative period is malnutrition, and rapidly progressing malnutrition which occurs in about 85% of pancreatic cancer patients. Abnormal nutritional status is closely related to a change in the composition in the body.The aim of the study was to determine the changes in the body composition of patients with pancreatic cancer and their consequences based on the results of the current research.The available reports have shown that the body composition of a patient with pancreatic cancer undoubtedly changes and is dependent on the stage, location and type of cancer. Furthermore, the fact if antitumor treatment is applied or not, also plays a significant role.It appears that in patients with pancreatic cancer, weight loss with a decline in parameters such as body fat and skeletal muscle mass appears early and worsens as the tumor grows and the disease progresses. The above data suggest that knowing the patient's body composition and observing its changes may be a prognostic factor for survival and the occurrence of complications. Additionally, there are reports that dosing chemotherapy based on body composition rather than conventional measures can help reduce the toxicity of the treatment. Therefore, knowing the patient's body composition seems to be an important aspect.

Organizational issues of home parenteral nutrition during COVID-19 pandemic: Results from multicenter, nationwide study.

OBJECTIVES: Patients on home parenteral nutrition (HPN) are prone to severe complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The pandemic requires adaptation of the health care standards, including epidemiologic surveillance, logistics of home supply, and monitoring. Potential lack of medical professionals may worsen the standard of care. The aim of this study was to evaluate the medical staff resources in HPN units. RESULTS: The study was conducted by major Polish scientific societies in clinical nutrition. A questionnaire was distributed among all Polish adult HPN centers concerning statistics from the first 3 mo of the pandemic (March through May 2020). Data on medical staff resources and organizational issues of the units were collected. Modifications of the home procedures, SARS-CoV-2 infection rates of HPN patients and health care workers (HCW) were analyzed. Influence of the pandemic on the rates of new qualifications for home artificial nutrition (HAN) was estimated. Fourteen of 17 adult Polish HPN units took part in the study. The point prevalence of HPN in Poland was 30.75/1 million citizens. Of HCWs, 344 were involved in patient care in Polish HPN units; 18.9% were physicians (49% surgeons, 18.46% internal medicine specialists, 15.38% anesthesiologists, 7.69% pediatricians, 1.54% palliative care specialists), 32.27% nurses, 5.23% dietitians, 9.01% pharmacists, 4.94% pharmacy technicians, 3.2% pharmacy assistants, 5.81% administrative workers, 3.49% physiotherapists. HAN patient-to-HCW ratios for physicians, nurses, pharmacists, dietitians were 49.5, 29.15, 111.6, and 181.6, respectively. Medium ages of physicians and nurses were 45.6 and 44.15 y, respectively. Slightly less than half (53.8%) of physicians and 31.53% of nurses worked parallelly in hospital wards. Thirty-one pharmacists overall were working in all HPN units (2.21 per unit) as were 18 dietitians (1.3 per unit). Nine patients had a confirmed COVID-19 infection (four HPN, five home enteral nutrition). All the units introduced telemedicine solutions in the first months of the pandemic. The number of new qualifications for HPN and home enteral nutrition in the units did not significantly decline from March through May in comparison with a similar period in 2019. CONCLUSIONS: A shortage of HPN medical professionals requires attention when planning health care organization, especially during a pandemic. Severe restrictions in public health systems may not reduce the number of new qualifications for the HPN procedure. There is a need for the continuation of data collection during the evolution of the pandemic as it may have a detrimental effect on HPN including serious issues with access to professional HCWs.

Home medical nutrition during SARS-CoV-2 pandemic - A position paper.

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of a worldwide rapidly spreading illness, Coronavirus Disease 2019 (COVID-19). Patients fed enterally and parenterally at home are exposed to the same risk of infection as the general population, but more prone to complications than others. Therefore the guidance for care-givers and care-takers of these patients is needed. METHODS: The literature search identified no relevant systematic reviews or studies on the subject. Therefore a panel of 21 experts from 13 home medical nutrition (HMN) centres in Poland was formed. Twenty-three key issues relevant to the management of SARS-CoV-2 infection or COVID-19 in the HMN settings were identified and discussed. Some statements diverge from the available nutrition, surgical or ICU guidelines, some are based on the best available experience. Each topic was discussed and assessed during two Delphi rounds subsequently. Statements were graded strong or weak based on the balance between benefit and harm, resource and cost implications, equity, and feasibility. RESULTS: the panel issued 23 statements, all of them were graded strong. Two scored 85.71% agreement, eleven 95.23%, and ten 100%. The topics were: infection control, enrolment to HMN, logistics and patient information. CONCLUSIONS: the position paper present pragmatic statements for HMN to be implemented in places without existing protocols for SARS-CoV-2 pandemic. They represent the state of knowledge available at the moment and may change should new evidence occurs.

Home Enteral Nutrition in Adults-Nationwide Multicenter Survey.

Home enteral nutrition (HEN) is an important part of the health care system, with a growing population of patients around the world. The aim of our study was to analyze one of the largest cohorts of HEN patients to provide the most recent data available in European literature. A multicenter, nation-wide survey in the period of 1 January 2018-1 January 2019 was performed in Poland. Data concerning adult patients on HEN in 2018 during 1 year of observation time were analyzed: demographic characteristics, primary disease, technique of enteral feeding, diet formulation and amount of energy provided. A total of 4586 HEN patients (F: 46.7%, M: 53.3%) were included in the study. The primary diseases were: 54.5% neurological (17.4%-neurovascular, 13.7%-neurodegenerative), 33.9% cancer (20.2%-head and neck, 11.7%-gastrointestinal cancer), 2.5%-gastroenterology, 1.5%-inherited diseases. Of new registrations in 2018-cancer patients 46.3%, neurological patients 45.1%. The median age overall was: 64 yr., BMI-20.2 kg/m2, NRS 2002 score-4.28. A total of 65% of patients were treated with PEG, 11.6% with surgical gastrostomy, 14.3% with naso-gastric tube and 7% with jejunostomy. Boluses were the most common method of feeding (74.4%). Gravity flow was used in 17.6% and peristaltic pump was used in 8% patients. The median energy provision was 1278 kcal/day and 24 kcal/kg/day. The most commonly used diets were: isocaloric (28.1%), protein-enriched isocaloric (20%) and protein-enriched hypercaloric (12%). The median overall duration of HEN was 354 days, 615 days for neurological and 209 days for cancer patients. A number of new registrations of cancer patients was significant and long duration of HEN in this group is encouraging. A developing spectrum of enteral formulas available enables more specified nutritional interventions.

Significance of selected morphological and histopathological parameters of colon tumors as prognostic factors of cancer spread.

BACKGROUND/AIMS: The identification of prognostic factors of metastatic development is one of the most important issues in colorectal cancer (CRC) research. The aim of this study was to determine the usefulness of colon tumor characteristics, including location, circumferential location, histological type, and histological grade, as predictors of metastases. MATERIALS AND METHODS: To identify potential predictors of CRC spread, we analyzed data of 191 patients who had undergone surgery for colon tumors. We searched for potential associations between the location in the right or left colon, circumferential location, histological type, and histological grade (G-parameter) of colon tumors and the incidence of lymph node and distal metastases. The analysis was based on Pearson's chi-square (χ2) test with a statistical significance of p<0.05. RESULTS: Lymph node metastases were found in 100 patients, including 44 patients with synchronous liver metastases. Lymph node involvement was detected in 43 (52.4%) patients with right-sided and in 57 (52.3%) patients with left-sided tumors (p=0.984). Liver metastases were detected in 19 (23.17%) patients with right-sided colon tumors and in 25 (22.9%) patients with left-sided tumors (p=0.969). Lymph node and liver metastases were found in 60 (47.6%) and 24 (19.0%) patients with annular tumors, respectively (p=NS), and these were found on the mesenteric side in 75.0% (n=30) and 20.0% (n=8) patients (p=0.004) and on the antimesenteric side in 47.6% (n=10) and 48.0% (n=12) patients (p=0.044), respectively. CONCLUSION: The circumferential location of primary colon tumors is a significant predictor of their metastatic potential. The mesenteric location of the tumor is predisposed to lymphatic spread, whereas the antimesenteric location predicts hematogenous spread.

Co-existence of insulinoma and diabetes: A case report.

Neuroendocrine tumors constitute a group of heterogeneous neoplasms, both those that are clinically asymptomatic and those which present with an array of symptoms. This variable clinical manifestation and unsatisfactory detection rate on diagnostic imaging make preoperative diagnosis particularly challenging. Insulinoma is a rare tumor originating from insulin-synthetizing pancreatic beta cells which clinically manifests hypoglycemia. The current study presents the case of a patient with a one month history of diabetes, and a tumor of the pancreatic head diagnosed at the Regional Hospital of Lomza (Lomza, Poland). The patient subsequently underwent surgery. The histological examination indicated insulinoma; islet cell tumor of the pancreas. The patient's postoperative period was uneventful and during two years of follow-up, the patient has remained in good health with completely controlled diabetes mellitus. The hereby-presented case of pancreatic insulinoma confirms this finding, as a correct diagnosis could only be established on the basis of pathomorphological examination. In addition, radical surgical resection is currently the only available treatment.

Own experiences of endoscopic self-expandable stent placement for malignant colorectal ileus.

INTRODUCTION: Acute low neoplasm ileus requires emergency surgery. Nowadays there are increased numbers of patients with comorbidities, which causes higher risk of intra- and postoperative complications. AIM: To evaluate the clinical usefulness of endoscopic self-expandable stent placement for malignant colorectal ileus. MATERIAL AND METHODS: Twenty-one patients (8 women and 13 men), mean age 66.7 years, with low neoplasm obstruction, underwent endoscopic stenting of the stricture. This procedure was performed as a bridge to the surgery especially for high-risk patients. Eight of them had coagulation system impairment, 5 severe metabolic disorders, 4 circulatory insufficiency, 3 severe malnutrition and 1 patient undiagnosed synchronic rectal tumor. In 10 patients cancer was located in the sigmoid colon, in 7 in the rectum, in 2 in the ascending colon, and the transverse and ascending colon was involved in another 2 patients. RESULTS: All 21 patients (100%) underwent endoscopic stenting successfully. There were no complications after stent placement. The authors underline that placement of expandable metallic stents for patients with malignant colon obstruction with acute ileus is a safe and effective method. It gives an opportunity for quick balance of fluid, electrolyte, and the coagulation system and improvement of efficiency of the circulatory and respiratory system. CONCLUSIONS: Endoscopic treatment of ileus helps precisely estimate tumor advancement and gives the possibility of a single stage radical surgical procedure.

A Rare Spontaneous Gastrobiliary Fistula.

We report the case of a 69-year-old man with a spontaneous gastrobiliary fistula. Internal biliary fistulas are usually the result of longstanding, untreated choledocholithiasis, cholecystolithiasis, peptic ulcers or rarely neoplasia. This patient's unspecific clinical picture led to a late diagnosis, which was made during surgery. How to cite this article: Chwiesko A, Jurkowska G, Kedra B, Okulczyk B, Kamocki Z, Dabrowski A. A Rare Spontaneous Gastrobiliary Fistula. Euroasian J Hepato-Gastroenterol 2014;4(2):101-103.

The effect of perioperative immunonutrition on the phagocytic activity of blood platelets in advanced gastric cancer patients.

BACKGROUND AND AIMS: Perioperative immunonutrition can influence the phagocytic activity of platelets in advanced gastric cancer. METHODS: 51 patients with stage IV gastric cancer divided into four groups depending on the clinical status and 40 normal donors were analyzed. Patients of groups I and II underwent palliative gastrectomy. Patients of groups III and IV had exploratory laparotomy. Perioperative immunonutrition was administered as follows: group I--TPN, II--oral arginine, peripheral TPN, III--TPN preoperatively, and IV--without nutrition. The phagocytic activity of blood platelets was determined before and after nutritional therapy and was assessed by measuring the fraction of phagocytic thrombocytes (%phag) and the phagocytic index (Ixphag). RESULTS: The percentage of phagocytizing platelets and the phagocytic index prior to and after the surgery amounted to the following: group I--1.136-1.237, P = NS, and 1.007-1.1, P = NS, respectively, II--1.111-1.25, P < 0.05, and 1.011-1.083, P < 0.05, III--1.112-1.186, P = NS, and 0.962-1.042, P = NS, and IV--1.085-0.96, P = NS, and 1.023-1.04, P = NS. CONCLUSIONS: The phagocytic activity of platelets in patients with advanced gastric cancer is significantly impaired. Perioperative immunonutrition with oral arginine-rich diet can partially improve the phagocytic activity of blood platelets. This trial is registered with Clinicaltrials.gov--NCT01704664.

Primary splenic angiosarcoma - the same diagnosis yielding two different clinical pictures. Case report.

Splenic angiosarcoma has been presented as an extremely rare malignant tumour. Amongst the rarest of all neoplasms, primary splenic angiosarcoma comprises 0.14-0.25 of all annually reported cases per one million persons Splenic angiosarcoma was first described in 1879 by T. Langerhans. The clinical symptoms and diagnostic values associated with splenic angiosarcoma are extremely variable. Nonetheless, majority of the patients (75%) complain of abdominal pain, and a quarter to one-third present with rupture of the involved organ. We hereby report our experience with two splenic angiosarcoma cases, which despite being similar in their diagnosis, nonetheless present with an entirely different clinical picture. Our first case, whereby the patient presented with a liver that was also affected by the angiosarcoma of the spleen. In the second case however, although the patient did show evidence of metastasis to the abdominal cavity as well as the liver, she also suffered from primary adenocarcinoma of the colon. To our knowledge, no previous article has made mention of primary splenic angiosarcoma existing independently of another primary neoplasm. Both may be found in common practice, and ought to be highlighted for their significance as such.

Assessment of platelet activation and phagocytic activity in gastric cancer patients.

AIM: To assess the activation of platelets and their phagocytic activity in the course of gastric cancer. METHODS: Forty-three gastric cancer patients were recruited to the study. The patients were divided into 3 groups depending on tumor stage. Group E included 6 patients with early gastric cancer; group A 18 patients with locally advanced cancer; and group M-19 with metastatic cancer. The investigations were performed twice, prior to surgery and 12-14 d afterwards. RESULTS: The platelet count and the level of soluble platelet selectin (sP-selectin) were found to increase with the disease progression. The level of sP-selectin was lowest in early cancer and was observed to increase after surgery in all the study patients. Irrespective of tumor stage, a statistically significant decrease was noted in the percentage of phagocytizing platelets and in the phagocytic index in gastric cancer patients as compared to healthy subjects. Despite increased platelet count and stimulation of thrombocytopoiesis, the phagocytic functions of blood platelets were markedly impaired. Tumor development seems to impair metabolic processes. CONCLUSION: A decreasing phagocytic activity can promote both inflammatory processes and cancer growth.

Platelets and inflammatory markers in patients with gastric cancer.

The aim of the study was to assess the contribution of platelets and inflammatory markers in gastric cancer. We studied 50 patients. Taking into consideration the advancement of gastric cancer, patients were divided into 3 groups. Group (E)--13 patients with early gastric cancer, group (A)--18 patients with regionally advanced cancer, and group (M)--19 patients with metastatic cancer. The determinations were performed twice prior to surgery and after surgery. In patients with gastric cancer, there is an increase in IL-6 and IL-23 compared with the healthy group. The highest values of IL-6 were obtained in early cancer (more than 8-fold increase), which seems to confirm the presence of acute inflammation. The lowest value of both of these cytokines was obtained in patients with metastatic cancer. In all patients, regardless of tumor stage, there was an increase in the concentration of CRP. An increase of PLT, higher proportion of the percentage of large platelets (LPLT), and increased mean platelet volume (MPV) were observed in the process of disease development. A positive correlation between MPV and LPLT and the accompanying decrease in the concentration of proinflammatory cytokines indicates the presence of an existing relationship between the platelet morphological parameters and the inflammation process in the development of gastric cancer.

Hereditary mixed polyposis syndrome--own experience.

Hereditary mixed polyposis syndrome (HMPS) is a rare condition of unknown genetic origin. The paper presents 25-year clinical follow up in a female patient with multiple gastrointestinal tract polyps of varied histology. They most likely served as sites of multiple colorectal cancers development. The clinical course is interesting in terms of diagnostics and therapy. The patient required extended genetic testing, intensive conservative treatment and numerous surgical procedures. This is the first case of HMPS presented in Polish publications.

Angiosarcoma of the large intestine - a case report.

Hemangioendotheliomas are poorly differentiated neoplasms built from strands of endothelial cells and have a very narrow lumen filled with blood cells. Hemangioendotheliomas are commonly detected during the initial six months of life, concerning mainly soft tissues and skin. It is the most common bening liver cancer in children. In adults, hemangioendotheliomas are very rare findings, being mostly described in the liver, lungs, brain and bones. Hemangioendotheliomas of the large intestine are extremely rare in adults. Cancer developing there is of high degree of malignancy. The authors present the case of 68 year old patient in whom preoperative benign tumor with ulcers were diagnosed. Intraoperative macroscopic picture suggested malignant process. The patient underwent anterior rectal resection with regional lymphadenectomy. The postoperative histopathological evaluation with immunohistochemical studies angiosarcoma was diagnosed. A four year survival free of cancer was obtained, and the patient died due to myocardial infarct. Literature describes the short periods of survival of patients with vascular sarcoma of the colon. The most common reason for decease are metastases with massive haemorrhages. Bleeding tendency results from growing Kasabach-Merritt syndrome. It is characterized by profound thrombocytopenia and coagulopathy. The presented patient is a unique example of angiosarcoma with long period of survival.

Double tract reconstruction (DTR) - an alternative type of digestive tract reconstructive procedure after total gastrectomy - own experience.

UNLABELLED: The only proven, effective therapy in case of the gastric cancers is surgery. THE AIM OF THE STUDY: The most common procedure which is made in such a situation is total resection of the stomach. In our publication we would like to present and to recommend a very rare made type of the reconstructive procedures after total gastrectomy, which is called "double tract reconstruction" (DTR). This type of reconstruction is occasionally made mainly in Japan.Material and methods. Double tract reconstruction has been made in 2nd Department of General and Gastroenterological Surgery since 2000. Till today 75 patients were treated with this method. RESULTS: The frequency of complications after double tract reconstruction was occasional, and there were no differences between this procedure and Roux-en-Y method of the reconstruction. There were no differences in the time of the operation between this two methods. The most important advantage of this method is that duodenal passage is extant. Because of that the endoscopic examination of papilla Vateri can be made. CONCLUSIONS: We would like to recommend this method as an alternative to Roux-en-Y procedure because of its simplicity and safeness.
