UNLABELLED Percutaneous endoscopic gastrostomy (PEG) is the most commonly used method of access to the gastrointestinal tract in long‑term home enteral nutrition (HEN) in patients with neurogenic deglutition and stenosis of the upper gastrointestinal tract caused by tumour. One of the most common complications of HEN is pneumonia resulting from aspiration of saliva or food. The risk of aspiration and the potential consequent sudden death is further increased by concomitant delayed gastric emptying and gastroesophageal reflux disease. The aim of the study was to evaluate the efficacy of changing percutaneous endoscopic gastrostomy to a gastrojejunostomy inserted through the PEG (PEG-J) in the prevention of aspiration pneumonia. MATERIAŁ AND METHODS: The study involved 158 patients receiving HEN by percutaneous endoscopic gastrostomy (PEG), aged 19 to 90 years. Indications for enteral nutrition in the study subjects included: neurogenic dysphagia--95 patients (60%), and obstruction of the upper gastrointestinal tract due to cancer--63 patients (40%). RESULTS The pulmonary and gastrointestinal complications were observed in 28 patients receiving gastric nutrition through PEG within one to nine months following the start of the feeding. In 20 patients, because of the symptoms of aspiration pneumonia with accompanying gastroesophageal reflux and delayed gastric emptying, PEG was changed to PEG-J as an alternative. There were no reports on food reflux and aspiration pneumonia in patients whose PEG has been replaced by PEG-J. CONCLUSIONS The use of PEG-J appears to prevent the occurrence of aspiration pneumonia in patients receiving home enteral nutrition in the long-term.

UNLABELLED According to the ESPEN and ASPEN guidelines, in the case of a long-term (>3-month) parenteral nutrition should be administered via a subcutaneous central venous catheter (CVC). There are three types of mechanical complications of tunnelled central catheter: catheter rupture, occlusion by TPN depositing and thrombofibrotic occlusion. The aim of the study was to analyse the incidence of complications central catheter in a group of patients receiving HPN. MATERIAL AND METHODS Between January 2010 and June 2014, HPN was conducted in 584 patients (306 women and 278 men), ninety-nine patients were enrolled in the study: 67 women and 32 men in whom mechanical complications of central catheters were found. RESULTS Among 99 patients, 71 used the tunnelled Broviac catheter. Groshong catheters were placed only in patients receiving parenteral nutrition due to cancer. Analyses have shown differences between the older and younger in the number of mechanical complications. Younger patients were found to have a larger number of catheter complications (1.6 ± 1.1) in comparison with older patients (1.3 ± 0.7). The catheter that was most commonly damaged was the Broviac catheter 76.8%. The most frequent type of mechanical complications was catheter rupture 64.81%. CONCLUSIONS Mechanical complications of tunnelled central catheters in HPN patients can be repaired in an outpatient setting in half of the cases, which enables continuation of parenteral nutrition without the need to hospitalise the patient. The centres that conduct HPN should offer 24-hour care and help in case of problems with the central venous line to the patients.

BACKGROUND & AIMS Home parenteral nutrition (HPN) enables patients who cannot eat normally to survive and function. Catheter-related bloodstream infections (CRBSIs) are the most dangerous complication, which may be fatal if left untreated or if treatment is delayed. For over 20 years CRBSIs were managed by catheter removal and implantation of a new one after completion of antibiotic treatment. However, frequent catheter replacements put the patient at risk of large vein thrombosis, which may render parenteral nutrition impossible. The management of CRBSIs evolved into antibiotic treatment without catheter removal. The effectiveness of this approach was, however, limited by the low penetration of the antibiotics into the biofilm. Filling catheters with concentrated ethanol destroys the biofilm and does not result in the emergence of drug resistance. The aim of our study was to assess the remote outcomes of CRBSI treatment using two approaches: antibiotic-ethanol lock therapy and catheter replacement. METHODS We retrospectively analysed the treatment outcomes of CRBSI diagnosed and managed in HPN patients. During the analysed period, a total of 428 patients between 13 and 96 years of age were on HPN and a total of 181 of them suffered a total of 352 CRBSI episodes managed with one of the two approaches. RESULTS We showed no significant differences between the two approaches in terms of survival likelihood or duration of catheter use after an episode of CRBSI caused by various bacterial species. CONCLUSION The use of antibiotic-ethanol lock therapy in the management of CRBSI is equally effective as catheter replacement.

UNLABELLED The issue of the quality of life considering patients with a temporary or permanent intestinal stoma, as well as the necessity for chronic parenteral nutrition at home remain a poorly understood problem. Daily care of the intestinal stoma and the need to comply with sterile procedures required for parenteral nutrition require such patients to commit their time, which secondarily is associated with the broad aspects of social and personal life. The aim of the study was to analyse the quality of life considering patients with intestinal stomas subjected to chronic parenteral nutrition, before and after gastrointestinal tract continuity restoration. MATERIAL AND METHODS The survey was conducted between May and July, 2014 on a group of 71 patients (33 female and 38 male) who were under the care of the Department of General Surgery and Clinical Nutrition, Warsaw Medical University, operated during the period between 2007 and July, 2014 with a present stoma (32 patients - 45%), as well as after stoma closure (39 patients - 55%). The analysed questionnaire contained 31 questions, and the SF-36 questionnaire was additionally used, determining the quality of life. RESULTS Analysis of the study material showed differences in the quality of life, considering three most important determinants. Significantly worse assessment of the quality of life was reported by patients with a stoma and subject to intravenous nutrition (83.2±30.5), as compared to those after stoma closure subject to normal nutrition (52.3±33.8). Based on the SF-36 questionnaire differences between patients with a stoma and those without amounted to t(69)=2.84 (p=0.006) demonstrating that those with a stoma reported a lower quality of life. Analysis between younger and older patients, based on the SF-36 questionnaire (t(62.87)=2.49; p=0.016) showed that younger patients achieved lower results, considering dissatisfaction with life (61.55±27.5), as compared to the elderly (80.8±36.9). CONCLUSIONS The group of patients without a stoma seem to be more independent- the vast majority do not use the help of family members (43.6%), or friends (64.1%). Patients with a stoma more often withdraw from social life. The factor that mostly reduces the quality of life is the presence of a stoma, which impairs daily functioning a lot more than the sterile procedures associated with parenteral nutrition. All patients after stoma closure consider that their overall functioning has significantly improved.

UNLABELLED Irritable bowel syndrome (IBS) belongs to functional gastrointestinal disorders and is characterized by abdominal pain and change in stool consistency and/or bowel habits. Etiological factors include gastrointestinal peristalsis disturbances, visceral hypersensitivity, chronic inflammation of the mucous membrane, dysbacteremia, intestinal infections, psychosomatic and nutritional factors. Gastrointestinal motility disturbances in case of IBS are manifested by the inhibition of the intestinal passage, which favors the development of constipation or occurrence of diarrhea. The aim of the study was to evaluate IBS symptoms and demonstrate the relationship between physical activity and place of residence amongst Warsaw University students. MATERIAL AND METHODS The study was conducted in march, 2014 using a specific questionnaire, amongst Warsaw University students. The study group comprised 120 female patients, aged between 19 and 27 years (M=23.43; SD=1.29). The chi-square test was used for analysis, p<0.05 was considered as statistically significant. RESULTS The BMI of investigated patients ranged between 16.30-31.22 kg/m2 (M=21.27; SD=2.71). The majority of respondents (76.6%) weighed within the normal limits. Abdominal pain or discomfort occurred more frequently in the group of students who considered their physical activity as low. In case of respondents with a low physical activity bowel movement disorders and stool continence changes occurred more often, as compared to those with moderate physical activity. The most common symptom was rectal tenesmus, the least common-presence of mucous in the stool. Analysis showed that students with low physical activity were more frequently absent from school/work, due to abdominal symptoms. The respondents with moderate activity more often considered their abdominal symptoms, being associated with stress. CONCLUSIONS IBS symptoms are common amongst Warsaw University students. In case of respondents with low physical activity, abdominal pain or discomfort occurred more often. It has been demonstrated that diet and stress might contribute to the occurrence of abdominal symptoms, being evidence of IBS.

UNLABELLED Home enteral nutrition (HEN for short) allows practically normal living for patients who cannot be fed orally but at the same time do not have to stay in hospitals, which is often found to decrease their mental condition, increase of probability of complications and costs of medical treatment. The aim of the study was to analyze the frequency of nutritional, mechanical and septic complications in patients fed enterally in home conditions. MATERIAL AND METHODS The study performed using retrospective analysis of study results and reports from control visits for patients in the period between 2012-2013. 147 patients fed enterally using HEN method participated in the study, including 70 men and 77 women aged 19 to 99 years (average 65 years). The following type of gastrointestinal tract access was used for patients: PEG in 113 (76.5%), feeding jejunostomy - 21 (1.4%), PEG-PEJ - 5 (3.5%), in case of the remaining 8 patients the nasogastric gavage (5.5%) was used. RESULTS The most common complication were infections (of gastric tract, skin soft tissue in the region of nutritional fistula entry, in three cases the aspiration pneumonia was diagnosed) found in 55 (49.1%) of cases. Mechanical complications were found out in 29 (25.9% of all complications), nutritional complications were present 28 times, which constituted 25% of all complications. CONCLUSIONS In the studied group of patients with an implemented HEN procedure, septic complications were the most common problem. The longest average nutrition time with PEG-PEJ probably results from the effective protection of the patient against aspiration pneumonia.

UNLABELLED If planned improperly, parenteral nutrition may result in a number of severe metabolic complications caused by insufficient or excessive delivery of individual nutrients. One of the most common and the most dangerous complication is parenteral nutrition-associated liver disease (PNALD). Such a complication may also result from using RTU (ready-to-use) bags that are not adjusted adequately to individual patients. The aim of the study was the analysis of prevalence and determining the cause of liver disease in patients who had been receiving parenteral nutrition in primary centres prior to the implementation of home parenteral nutrition in the specialist centre. MATERIAL AND METHODS The study enrolled 146 patients who were referred to the Clinic in the period of 2006-2012 in order to be qualified for home parenteral nutrition. Interview and medical documentation revealed that 100 patients had been receiving parenteral nutrition by means of ready-to-use (RTU) bags in their primary centres. In the remaining 46 patients, such feeding had not been implemented. Upon admission, the following parameters were evaluated: bilirubin, aspartate aminotransferase (AspAT), alanine aminotransferase (AlAT), lactate dehydrogenase (LDH), gamma-glutamyltranspeptidase (GGTP), alkaline phosphatase (AP), triglycerides (TG), cholesterol, protein, albumins, amylase, urea, creatinine and C-reactive protein (CRP). The analysis of the results was conducted with the use of the Students T-test. RESULTS The patients who had been receiving parenteral nutrition manifested significantly increased (p < 0.05) levels of total bilirubin, TG, AlAT, LDH, GGTP, AP and CRP. 23% of patients were diagnosed with jaundice, in 70%, GGTP > 100 i.u. and a half manifested biochemical features of cholestasis. No correlation was observed between the CRP level and results of liver function tests. CONCLUSIONS It was found that there is a correlation between parenteral nutrition with RTU bags and liver disease. The probable cause of liver disease associated with parenteral nutrition received prior to the transfer to the Clinic is excessive administration of lipids. It can be accompanied by excessive administration of glucose. Modification of parenteral nutrition helped to compensate for liver disorders in all patients.

INTRODUCTION Resection is an optimal way of treatment of hepatic tumors and metastasis from another organ. The operational injury may influence on patients body composition examined by bioelectrical impedance (BIA). Analysis of parameters may be helpful in identifying early changes indicating of deterioration in nutritional status. THE AIM OF THE STUDY was to assess changes in body composition of patients before and after resection of liver tumors and potential radiofrequency ablation of lesions. MATERIAL AND METHODS The study included a group of 50 patients of the Department of General, Gastroenterological and Oncological Surgery, Medical University of Warsaw, who were qualified for radical surgical treatment of tumors within the liver. Data on water content, fat, muscle and cell mass were analyzed. RESULTS Comparing data obtained from patients before and after intervention in the liver, statistically significant (p <0.05) loss of intracellular water, muscle mass, cell mass, as well as adipose tissue, was demonstrated. The phase angle value in these patients also significantly changed, decreasing by an average of 0.61°. On the other hand, the increase in content was noted in the case of extracellular water. CONCLUSIONS Surgical intervention within the liver causes noticeable, unfavorable changes in the body composition, as evidenced by the reduction in the value of muscle mass, as well as cellular mass, resulting in a decrease in the phase angle. Bioelectric impedance is a suitable method for assessing changes in body composition of patients undergoing liver resection and is useful in clinical practice. It is advisable to conduct further research in the group of patients undergoing invasive treatment of the liver due to: an increasing number of such operations and centers where this type of surgical intervention is performed.

Introduction An end stoma syndrome is usually the result of an intentional surgical intervention in the course of staged treatment or a complication of surgery. These patients most frequently suffer from water and electrolyte disturbances, malnutrition syndromes caused by malabsorption of trace elements and/or vitamins, and undernutrition. Aim To present early metabolic disturbances observed in patients with an end jejunostomy or end ileostomy syndrome on the first day of their hospitalization in a specialist Home Parenteral Nutrition (HPN) center. Material and methods The study included 142 patients with an end stoma syndrome (76 women and 66 men), hospitalized between 2004 and 2014. Patients were divided into two main groups. Group A consisted of 90 patients with an end jejunostomy and group B consisted of 52 patients with an end ileostomy. Results After comparing the patients with an end jejunostomy vs. those with an end ileostomy, significant differences were found as regards pH (7.34 vs. 7.39, p = 0.043) and BE (3.24 vs. –0.86, p = 0.005). Depending on the lack or possibility of oral food intake, patients in the end jejunostomy group had different levels of the markers phosphate, Mg, Ca, urea, and creatinine, with all of these parameters within normal laboratory limits. When the end ileostomy group was divided into subgroups depending on the lack or possibility of oral food intake, differences in C-reactive protein activity were found (55.6 vs. 25.7, p = 0.041). Conclusions Patients with an end jejunostomy syndrome are more prone to metabolic acidosis with significant alkali deficiencies.

Introduction The ESPEN guidelines on long-term (> 3 months) parenteral nutrition recommend the use of tunnelled central venous catheters (CVCs) to minimise the risk of insertion site infection. A developed symptomatic infection of the soft tissue tunnel surrounding a CVC may rapidly become directly life threatening if the infection progresses along the catheter tunnel towards its end inserted into the venous system. This requires immediate management to eliminate infection and limit its effects. Aim To compare two surgical techniques for the treatment of suppurative inflammation of a CVC tunnel: conventional drainage of the infected tissues (surgical technique A) vs. radical en bloc excision of the infected tissues together with the infected central catheter (surgical technique B). Material and methods Seventy-three patients hospitalised due to CVC tunnel phlegmon between April 2004 and May 2014 were included in the retrospective study. Thirty-four (46.5%) patients underwent surgical procedure A and another 39 (53.5%) underwent procedure B. Results The mean duration of antibiotic therapy following procedure A was 8 ±3 days, whereas procedure B required 7 ±2 days of antibiotic therapy (NS). The mean hospitalisation period following procedure B was over 8 days shorter in comparison to that following procedure A (16.54 ±7.59 vs. 24.87 ±10.19, p = 0.009, respectively). Conclusions The surgical treatment of CVC tunnel phlegmon involving radical en bloc excision of suppurated tissues along with the infected CVC shortens hospitalisation, expedites the insertion of a new CVC, and potentially reduces treatment costs.
