[Postoperative lavage treatment of chronic pancreatic abscess].

The authors present their experiences in treatment of chronic pancreatic abscess and infected pancreatic necrosis. In this paper they refer to patients only whose acute necrotizing pancreatitis occurred 4-6 weeks earlier and had intra- and peripancreatic abscesses. They describe their successful lavage method for treatment of pancreatic abscesses. Between 1985 and 1998 they treated 16 patients with only one mortality. The majority of their patients were relatively old and most of them suffered from several severe unrelated diseases. In their opinion, careful dissection and long period of lavage and drainage are a successful method for treating this high-risk surgical group.

[Treatment of open wounds of the heart and the pericardium: analysis of the relation between the time factor and diagnostic procedures].

Authors summarize their experiences connected with the treatment of open wounds of the heart and the pericardium during the past 35 years. Between 1962 and 1997 the authors operated on 31 cases of injuries affecting the heart. 10 wounds were situated in the isolated pericardium. They also deal with the history of treating injuries of the heart and pericardium. The value of diagnostical procedures was analysed and compared with Hungarian literature data that describes further cases. They emphasize the importance of immediate physical examination (including that of circulation, breathing, heart rate, consciousness, etc.) in cases of wounds close to the heart. Authors discuss the effects and the importance of the circumstances that directly affect the life expectancy of the patient during the treatment, such as time factor, the planning of cooperation within the operating team, practice in the field of thoracic surgery and management. They also put stress on correct thoracotomy, drainage and suction, so as to avoid postoperative pleural complications.

[Initial experiences in drainage operation for refractory ascites with saphenous valves].

Authors explains his operational procedure for the treatment of refractory ascites to replace generally used shunt types (LeVeen, Denver, Agishi). It means leading ascites fluid from the abdominal cavity into the venous system with the help of a silicone drain. For maintaining one-way flow they he used the double saphenous valve before the sapheno-femoral junction. They gives a step by step description of the procedures applied during the operation and also explains the first results. The method well deserves attention and further examination because it is simple, cheap and reliable due to the use of saphenous valves coming from the body itself.

[Technical difficulties of microlaparotomy for cholecystectomy].

Microlaparotomy cholecystectomy (MLC) is an alternative for minimal invasive surgical interventions of the biliary tract. In Hungary over 7000 operations were performed in 21 surgical departments as at December 31. 1998 and numerous additional departments have indicated their demand for the initiation of the method. Every new surgical procedure requires a "learning curve" during the application of MLC, difficulties encountered with the surgical solution occurred in a 14-15% range. We studied difficulties noticed during micro-, minilaparotomy cholecystectomy in 2400 unselected cases from the adoption of the surgical method in our department until December 31, 1998. We grouped our findings into avoidable, and unavoidable difficulties. Circumstances that can present unavoidable difficulties include: the patient's abnormal change in build, surgical interventions that have to be performed on patients 8-10 days after obstructive cholecystitis, abnormal gallbladder not indicated during preoperative examination, as well as biliary tract variations. A considerable part of the difficulties can be avoided by MLC-desirable positioning of the patient on the operating table, appropriate choice of surgical incision site and method, satisfactory anaesthesia, the use of necessary instruments suitable for exposure and unobjectionable illumination of the surgical area, as well as the performance of cholecystectomy with required modifications per given circumstances. The concomitant 2.5-16% alternating conversion rate after minicholecystectomy is indicative of the importance of the use of instruments assuring adequate exposure and excellent illumination of the surgical area. During the practice in our department this occurrence was recorded in 0.29% with the use of the ROMICRO R-set.

[Results of parathyroidectomy for primary hyperparathyroidism].

We have performed 16 operations on 14 patients with primary hyperparathyoidism caused by a solitary parathyroid adenoma in our department between 1st jan. 1990-31 dec. 1999. In each case bilateral neck exploration was carried out. As in one case it was located in ectopic neck position, in the other case papillocarcinoma of the thyroid gland and ectopic parathyroid adenoma in mediastinal position were present, primary hyperparathyroidism persisted, so reoperation was needed. Histological examination proved the presence of adenomin all cases. Diffuse hyperplasia and parathyroid cancer did not occur. Before operation all patients underwent US and seven of them had radionuclide scintigraphy. CT scan aided in its localization with four patients. We did not make use of invasive methods, after the first operation 12 patients showed normal S-Ca levels very quickly. In two cases this level was too high after the operation and reoperation was necessary which resulted in normal Ca levels. Even though the number of our cases is rather modest, all the patients recovered. This may prove that we can successfully cure our patients of modern methods of diagnostics used for meticulous examination alongside with careful preparation of the patients by internal specialists are followed by the standard operative techniques available.

[Regional chemotherapy in thoracic surgery].

The authors introduce their experiences on intracavital chemotherapy of mainly secondary pleural and pericardial malignant effusions based on a 5 years term of routinely used practise. In the cases of patients proper to the indicational conditions palliative regional cytostatic treatment was applied through transthoracal and intraopericardial (inserted by modified Fontenelle method) drains in order to cessate definitively the exsudation to improve the quality of life.

[Primary manifestation of monophasic synovial sarcoma in the lung].

The authors introduce a case of a 41 years old male patient who was examined first on pulmonology department due to thoracic pain, haemoptoe and fever. In the background of symptoms a 10 cms diameter formation was found in the right thorax side joined to the hilus. Even a through row of examination was unable to determine the histologic type. After the patient's admittance to the authors' thoracic surgery department the tumor occupying the central part of the right upper pulmonary lobe was resected by lobectomy via right thoracotomy. The histologic result was monophasic synovial sarcoma of which primary pulmonary appearance is very rare. The authors consider the rarity of this tumor type worth to publish.

[Experiences with the modified Fontenelle operation for pericardial effusion].

The authors summarize their experiences on the surgical treatment of pericardial effusions by surveying the clinical data of patients in the last 4 years. They call attention on the advantages of subxyphoideal pericardium fenestration, the modified Fontenelle operation, which method is routinely used by them.

[Endoscopic pericardium fenestration].

Author describes thoracoscopic fenestration applied to treat pericardial effusion in an elderly patient with etiologically not identified chronic pericarditis. The operation can be performed easily, quickly and with minimal functional harm with the help of minimal invasive method. Thoracoscope gives a detailed view of the inner surface of the pericardial sac and the epicardium and the cutting of the pericardial window can be performed safely. Apart from description of operation technique applied the author gives a brief summary of place and significance of minimal invasive pericardial intervention in the treatment of the ever growing pericardial effusion.

[Correlation between long survival and shunt patency in patients treated surgically for refractory ascites].

The survival data of 31 patients operated on for refractory ascites in the 7-year-long period between 1983 and 1989 have been analysed in relation to the patency of the shunt. In the follow-up examination of the 7 patients who had survived 3 years flow-through contrast material was used and the patency of the shunt was documented by percutaneous injection of the contrast material under X-ray. The authors search for explanation in cases where the shunt was non-conducting (blocked) in ascites-free patients. No considerable difference was found between the two long survival assuring types of the shunt (LeVeen and Denver). 55% out of the 31 patients operated on had survived 2 years and almost 30% had survived 3 years.

Complications associated with the implantation of peritoneo-venous valves and possibilities of prevention.

The author describes the complications associated with the implantation of peritoneo-venous valves in the therapy of refractory ascites. They survey the various complications (disorders in the healing of the wound, valve occlusion, ascites induced coagulation disorders) observed during the treatment of 71 patients and give full account of their work performed while observing these complications, their prevention and avoidance. They stress the importance of haematologic examinations and postoperative haemostasis parameters of patients having undergone valve implantation.

[Umbilical hernioplasty with valve implantation in cirrhotic-ascitic patients].

The authors summarize the treatment results of patients managed by them suffering from umbilical hernia associated with intractable ascites. Through a period of 10 years, 17 out of the 164 patients operated on for umbilical hernia were cirrhotic with ascites. In the course of the presentation of the data of such treated patients, the authors point at the increased danger of postoperative complications in ascites-induced umbilical hernia, and the high mortality rate; facts backed up by data from previous study. On the basis of their experiences in ascitic-valve implantation over the past decade, during the past 3 years in 5 cases of refractory ascites-induced umbilical hernia, hernioplasty was performed together with ascitic-valve implantation at the same sitting. The observed good results unanimously speak in favour of the continuation of this method. The authors suggest that such patients have to be referred to those surgical departments/hospitals where the prerequisites for the above mentioned surgical method--personnel and material--are given.

Cytogenetic studies on rural populations exposed to pesticides.

The authors have carried out cytological analysis of 72 h lymphocyte cultures from peripheral blood and internal examinations of 80 workers professionally exposed to a complex of pesticides and that of 24 control persons. There was a significant increase of chromosome aberrations in relation to the duration of exposure. The additive role of alcohol consumption and smoking in evoking aberrations was also studied with inconclusive results because of the limited number of cases. Internal examinations revealed a more frequent occurrence of acute as well as chronic diseases among the workers aged 21-40 years.
