[INTRODUCTION - The leading role of laparoscopy in the surgical treatment of functional diseases of the gastro-esophageal junction has become indisputable. But has the time of the “classic”, open surgical interventions really gone for good? PATIENTS AND METHODS - Between January 1., 2000 and December 31., 2004 we performed hiatal reconstruction and antireflux plastics for 186 patients. 83.3% (155/186) of the operations was performed laparoscopically, while 16.7% (31/186) with the traditional approach. The average age of patients was 46.9 years, 7% of the operations was performed on children. In case of recurrent paraoesophageal hernias the surgical plan was drawn up based on the result of the barium swallow X-ray performed after endoscopic clipping of the Z-line. In case of a brachy-esophagus, we formed the neo-esophagus by performing the Collis-Nissen operation modified by us (Neodinium magnet + plastic sliding scale) from the traditional abdominal exposure. RESULTS - The indication for hiatal reconstruction and antireflux operation was sliding hernia in 68.2%, paraesophageal hernia in 17.8% and reflux disease in 14%. We observed signs of panmural esophagitis in 22%, while latent or true brachy-esophagus in 10.7%. Antireflux procedures were grouped as Nissen type operation in 82.7%, Toupet type in 9.67%, Narbona in 2.1%, Belsey-Mark IV in 1.61%, and resection type operation in 3.76%. To narrow the diaphragmatic openings, two sutures were needed in most cases (57.1%). Conversion to laparotomy was necessary in 3.2%. We observed recurrences in 3.3% after laparoscopic interventions. In case of open operations we experienced no recurrences in the studied period. The barium swallow X-ray examination performed after endoscopic clipping of the Z-line could reveal brachy-esophagus before the operation. CONCLUSION - Open surgical interventions can not fall into oblivion even in the age of laparoscopic hiatal reconstructions and antireflux plastics. Open surgical procedures are justified even in the new milennium in cases when the patient's medical history contains upper abdominal operations - due to an increased risk of injury because of adhesions -,in cases of primarily recurrent paraesophageal hernias after an unsuccessful open and/or laparoscopic reconstruction, as well as in cases of reflux with complications.]

[SUBCONJUNCTIVAL NEMATODE INFECTION]

ACZÉL Klára, DEÁK György, FARKAS Róbert, MAJOROS Gábor

[INTRODUCTION - Nematode infection of the eye occur only sporadically in the continental area. The pathogenic parasite in these cases is usually a Dirofilaria species, mostly D. repens. CASE REPORT - A case of human subconjunctival dirofilariosis is reported, where acquisition from abroad or animal contact in the background of the infection were excluded. The surgical removal of the entire living worm resulted in the complete cure of the patient. CONCLUSION - Knowing the occurrence of Dirofilaria infection of dogs and the increasing spread of the vector mosquitoes during the summer (in towns, too), the increasing occurrence of human dirofilariosis affecting the eye and orbital area in 10-20% of the cases must be taken into account.]

[THE CLINICAL PHARMACOLOGIC BASIS OF THE SAFE USE OF STATIN ANALOGS]

KERPEL-FRONIUS Sándor

[Statins, specific inhibitors of the 3-hydroxy-3-methylglutaryl- coenzyme A (HMG-CoA), decrease significantly pathologically elevated cholesterol levels. The effectiveness and the side effects of the different analogs depend on their inhibitory potency, lipid solubility, active uptake into the liver cells and on the difference in their metabolism. The statins can be divided into three groups on the basis of their clinical effectiveness: the highly effective agents are rosuvastatin and atorvastatin; simvastatin exhibits an intermediate activity, while lovastatin, pravastatin and fluvastatin are the least active drugs. The main metabolic pathways of the statins are oxidation and glucoronidation and finally the spontaneous inactivation by lactone ring formation of the glucoronidated products. Gemfibrozil increases the plasma level of all statin analogs by inhibiting the activity of UGT1A1 and UGT1A3 isoenzymes of the UDPglucoronosyltransferase. Therefore, when a statinfibrate combination is needed, fenofibrate and bezafibrate are recommended, the metabolism of which are linked to other UGT isoenzymes. Similarly elevated plasma levels are produced by inhibiting the specific cytochrome isoforms participating in the oxidation of a particular statin. Severe side effects are rarely observed. The most frequent adverse reaction is the development of myopathy of various severity. Using various statins rhabdomyolysis occurred in 0.0-0.3 cases /100 000 statin prescriptions if the already withdrawn cerivastatin is not considered. The statin+gemfibrozil combination increases the number of rhabdomyolysis approximately tenfold. The long-term benefit of statin therapy far exceeds the risk of the treatment. For achieving very low lipid target values even the most effective statins must be used in high doses. Nevertheless, this goal cannot be reached in about 20% of the cases. High dose statin treatment should be administered with the gradual increase of the dose, tight control of the patients and by meticulously selecting the drugs given simultaneously. Further development can be expected from the application of agents with new mechanisms of action, such as the cholesterol uptake inhibitor ezetimibe.]

[The diagnostic value of a glass of soda water in case of a cardiac space-occupying lesion]

PÁLINKÁS Attila, CZAKÓ László, CSÁSZÁR Ildikó, NAGY Edit, SZABÓ Marianna

[INTRODUCTION - Large hiatal hernias may result in cardiac space-occupying lesions. Our case study discusses the clinical aspects and the possible diagnostic approaches for such large hiatal hernias that cause cardiac compression. CASE REPORT - In an elderly patient with no cardiovascular symptoms, transthoracic echocardiography revealed a left atrial space-occupying mass. The diagnosis regarding the origin of the cardial mass was clarified by a glass of soda water drunk by the patient during echocardiography, as it resulted in a decrease in the inhomogenous echodensity of the mass and the appearance of “contrast bubbles” within it. This phenomenon suggested the presence of a large hiatal hernia compressing the heart, which was confirmed by gastroscopy and upper gastrointestinal barium examination. CONCLUSION - Drinking soda water during transthoracic echocardiography can help to diagnose lesions that look like intracardial tumours.]

[THE FACTORS BEHIND CHRONIC PELVIC PAIN]

SZENDEI György

[There are no data available on the prevalence of chronic pelvic pain syndrome in Hungary. Even international literature provides an equivocal view of this disease. Dealing with the pelvic pain syndrome puts not only the patients in a challenging situation but the health care system as well. In many cases the etiology and the pathophysiology of the disease is not very well known. Endometriosis, pelvic inflammatory diseases and postoperative adhesions are the most frequent causes of the pelvic pain syndrome. However, irritable bowel syndrome, interstitial cystitis and the pain caused by diseases of the musculosceletal or nervous systems can also be accompanied with similar symptoms. Although the organic mechanisms of the formation and the modulation of pain are well known, the psychological factors should also be taken account. Psychotic status may generate pain on its own, or may influence the experience of the pain. In case of pelvic pain syndrome, similarly to other chronic diseases, the biopsychosocial model tries to integrate the physical, psychological and social factors of the pain.]

[Economic relations of laparoscopic colorectal surgery in hopitals]

BENEDEK Zsófia, KRENYÁCZ Éva

[In this review, we compared economic and physiological observations reported in the literature that are related to laparoscopic versus conventional colorectal surgery. Our study group has modeled the patient journey of those with colorectal disease, and analysed the accounting and controlling data of an impatient institution in Budapest for various types of colorectal interventions. We compared the costs determined for laparoscopic and conventional colorectal surgery and the actual costs spent by the inpatient care institution with financing data of the National Health Insurance Fund. On the basis of our study, we conclude that in Hungary colorectal surgery performed by laparoscopy is much more expensive that conventional surgery as the cost of the operating room - in particular, the disposable tools - is high and currently it is not financed as a separate intervention type. In case of colorectal diseases, laparoscopic and traditional interventions have not been differentiated, observed and compared yet.]
