Urgent situations in phlebology--variceal bleeding and it's treatment.

The aim of this study was to compare the therapeutic results of patients whose bleeding points were sutured and patients treated with compression sclerotherapy. In the years 1983-2000, 56 patients with profuse bleeding from varicose veins were treated. In a subgroup of patients with compression sclerotherapy--Fegan's way (32 patients), bleeding wound was healed completely within 7 days on average (5-13). All ulcers have healed within 2 months. The presented approach used is a surgical procedure (stitch, removal of large varicosities). Fegan's technique of compression sclerotherapy, with a detergent sclerosing solution (S.T.D.), enables to complete sclerotherapy of all pathological reflux points during 1-2 visits not only with good results, but also as a one-day surgery, keeping the patient work (Ref. 7).

Conditions responsible for small bowel resection.

The authors deal with the problems of surgery of small intestine. They analyze causes leading to small bowel resection, including small intestinal obstructions, tumors, diverticles, Crohn's disease and traumas of small intestine, in a group of patients operated at Ist Department of Surgery, University Hospital, Commenius University, Bratislava, during the last 30 years. Authors also discuss the problems of short bowel syndrome (SBS) as the consequence of an extensive small bowel resection, reporting the surgical approach to its therapy. (Tab. 1., Ref. 5.)

The abdominal compartment syndrome.

The abdominal compartment syndrome has received considerable attention only recently. It may be defined as adverse physiologic consequences that occur as a result of an acute increase in the intraabdominal pressure. The most common causes of ACS are haemorrhage, visceral oedema, pancreatitis, bowel distension, venous mesenterial obstruction, abdominal packs, tense ascites, peritonitis, tumor. The mostly affected organ systems include cardiovascular, pulmonary, renal, central nervous and splanchnic. The diagnosis depends on the recognition of the clinical syndrome followed by an objective measurement of intraabdominal pressure, preferably that of the urinary bladder. The treatment consists of adequate fluid resuscitation and surgical decompression when necessary. (Tab. 1, Ref. 29.).

Long term results of compression sclerotherapy.

AIMS: To compare the short and long term results of different techniques of compression sclerotherapy. PATIENTS AND METHODS: In the past 10 years the authors treated 1622 pts due to chronic venous insufficiency. There were 3 groups of patients: 1) Pts treated by Sigg's technique using Aethoxysclerol, 2) Pts treated by Fegan's technique with Fibrovein, and 3) Pts treated by Fegan's procedure, but using a combination of both sclerosants. In all cases, the techniques of empty vein, bubble air, uninterrupted 6-week compression and forced mobilisation were used. RESULTS: In the group of pats. treated by Sigg's procedure, the average cure rate was 67.47% after 6 months, 60.3% after 5 years of follow-up. In Fegan's group this rate was 83.6% after 6 months and 78.54% after 5 year assessment. Statistically, significant differences were found only by the disappearance of varices and reduction of pain in favour of Fegan's technique. In the group of pts treated by Fegan's (Aethoxysclerol + Fibrovein) this rate after 5 years was 86%. The only statistically significant difference was found by the disappearance of varices in favour of Fegan's technique using a combination of 2 detergent sclerosants. CONCLUSIONS: Sclerotherapy is effective when properly executed in any length of vein no matter how dilated it has become. The recurrences are attributed more to inadequate technique than to the shortcoming of the procedure. Sclerotherapy is miniinvasive, with few complications, and can be repeated on out-patient basis. (Tab. 1, Ref. 22.).

Retrocaval ureter with ureteral carcinoma.

The authors report a rare congenital anomaly, retrocaval ureter (RCU) with carcinoma. The patient had recurrent pyelonephritis, hematuria and renal colic. Urography shows no function on right side. Abdominal ultrasound revealed marked right hydronephrosis. Antegrade ureterography through nephrostomy revealed a RCU. Helical C.T. confirmed the RCU and also revealed a defect in contrast medium in the upper ureter. We performed percutaneus antegrade nephro-ureteroscopy and found carcinoma of the retrocaval ureter. This may be the first case of tumor in the RCU. We did not find any other in the literature. (Fig. 3, Ref. 14.).

Oncological radicality in colonic cancer operation.

Lymphadectomy should extend to the level of the origin of the primary feeding vessel, suspected positive lymph nodes outside the standart resection should be removed when feasible. A minimum 5 cm bowel margins proximally and distally should be used and peroperative histology must confermend tumor free anastomosis. En-block resection should be performed for tumors adherent to local structures. Inadvertent bowel perforation increases the risk of recurrence and should be avoided. Ovaries grossly involved with tumor should be removed. In all women having operations for cancer of the colon bilateral oophorectomy should be performed. In premenopausal women the ovary is a frequent site for metastatic disease (the Krukenberg tumor) which occures as often as 25 percent of the time. The incidence of of ovarian metastasis is much lower in postmenopausal women but the consequences of oophorectomy are also less severe in that age group. (Ref. 9.).

Iatrogenic esophageal perforation--diagnosis and therapy.

The diagnosis and therapy of iatrogenic esophageal perforation in a group of patients treated for this condition. During the period of 1994-2002 twelve patients suffered iatrogenic esophageal perforation with a mortality rate of 33.3%. The therapeutical approach consisted of either primary repair of the perforation, drainage of the mediastinum and pleural cavity or inserting a stent. (Ref. 6.).

The treatment of venous leg ulcers by compression sclerotherapy.

PURPOSE: To assess the results of complex sclerotization therapy of pure venous ulcers on all levels of venous system. PATIENTS: Over the last 10 years the authors treated 698 patients with venous ulcerations and compared the therapeutic results in 3 groups of patients treated by Fegan's technique of compression sclerotherapy combined with an antireflux operation of the deep venous system in ulcers not responding to superficial and perforator therapy. RESULTS: 84% of patients with venous ulcers had pathological reflux in the deep venous system and all of them (100%) had insufficiency of the perforators. Using Fegan's technique of compression sclerotherapy the authors managed to heal 95.4% of ulcers with an average time of complete ulcer epithelialization of 39 +/- 12 days. The recurrence rate within 5 years was 18% (126 patients). The average time of disability during the course of sclerotisation was 7 days and no hospitalisation was needed. The healing process depends on the presence of reflux in the popliteal vein in statistically significant fashion. In patients, where a new valve was constructed or direct valvuloplasty was done, all ulcers (except 3) responded to the compression sclerotherapy and healed within 3 months. CONCLUSION: The authors consider compression sclerotherapy (Fegan's technique) to be the easiest and most effective way of treating patients with venous ulcers. Direct valve repair techniques are appropriate only in non-thrombotic deep vein reflux which is very rare (0.6% - 4 patients). In patients with torpid ulcers, where compression sclerotherapy failed (4.6% - 28 patients) in situ construction of a new venous valve helped to heal these ulcers. (Tab. 1, Ref. 18.).

Fournier's gangrene: can aggressive treatment save life?

Fournier's gangrene (FG) is a rapidly progressive, fulminant infection of the scrotum, perineum and the abdominal wall. FG is caused by synergic aerobic and anaerobic organisms. Modern surgical series report mortality of up to 67%. This originally rare disease has become more frequent. Aggressive treatment including antibiotics, antigangrenous serum, and treatment of all accompanied diseases and disorders can be successful. Treatment also includes debridement and plastic corrections. Authors describe management of 8 patients with FG. Treatment of FG and all accompanied diseases was in all cases successful. Treatment costs of this kind of patients were approximately 20 times higher than treatment of patients with other urologic diseases.

Could deep vein thrombosis be safely treated at home?

BACKGROUND: The aim of this prospective study was to analyse the group of patients with DVT (deep vein thrombosis) treated at home with LMWH (low-molecular weight heparin), compression, intensive mobilization. METHODS: 106 consecutive patients with the diagnosis of DVT were treated at home with enoxaparin (Clexane Rhône-Poulenc) administered subcutaneously (1 mg/kg) b.i.d. for a minimum of 7 days. All patients wore elastic second degree compression stockings during the whole treatment and for further 12 months, and were encouraged to walk 1-2 kms daily. In this group of 106 patients the upper limit of thrombosis was iliofemoral vein--45 pts (42.4%), femoral or popliteal vein--33 pts (31%), crural veins--28 pts (26%). The diagnosis was done by compression ultrasonography, by contrast phlebography, platelet scintigraphy (Tromboscint test). RESULTS: Perfusion gammagraphy of the lungs was done in 54 patients where thrombosis was localised in the popliteal and iliofemoral veins. In 28 patients there were signs of non-fatal pulmonary embolism (52%), but only 7 pts (25%) suffered from mild non-specific clinical signs; 21 pts (75%) with the diagnosis of pulmonary embolism were symptom-free. 8-12 weeks after this treatment, control sonography and phlebography were done in 75 pts (71%), in 53% (40 pts), we found partial, and in 32% (24 pts) total recanalisation. In the rest of 11 pts (15%) there were no signs of recanalisation. Compared with the group of patients treated by the classical method (UH, immobilisation) in the period from January 1995 to February 1997, out of 48 pts where the recanalisation was retrospectively analysed, 17 pts (36%) did not show any signs of recanalisation. The difference is significant (p < 0.01). In this group of 54 pts, 4 died of PE (post mortem verified) compared with no death in the group treated with LMWH and mobilisation. The difference is not significant (p < 0.9). Eighty six patients (81%) out of 106 were satisfied and pleased with home treatment and mobilization. From this group of patients treated with LMWH and forced mobilisation 46 were investigated after one year by duplex scan. None of these patient had recurrence, but 7 pts (15%) had pathological reflux (more than 0.5 s) in the deep venous system, majority of them--5 pts on the popliteal vein. CONCLUSION: Home treatment of DVT is possible and effective, safe and cost-effective. On the average, 40 percent of expenses per patient were saved when compared with hospital stay in spite of more expensive LMWH. The patients who received LMWH spent a mean of 1.2 days in the hospital, as compared with 12.7 days for the standard-heparin group. A long-term (12 months at minimum) of compressive stocking (45 mmHg) with activation of the muscle-venous pump by forced mobilisation can prevent recurrence and decrease the percentage of the post-thrombotic syndromes.

Transoral application of EEA stapler after subtotal oesophagectomy.

OBJECTIVE: To describe a new transoral technique of cervical oesophagogastric and oesophagojejunal anastomoses using the EEA stapler. DESIGN: Prospective clinical study. SETTING: University Hospital, Bratislava, Slovakia. SUBJECTS: Two patients with squamous cell carcinoma of the middle and distal third of the oesophagus. INTERVENTIONS: Transhiatal subtotal oesophagectomy without thoracotomy, and cervical oesophageal anastomosis by transoral EEA stapling. MAIN OUTCOME MEASURES: Morbidity and mortality. RESULTS: Transoral stapling was successful in both patients with no anastomotic leaks. The patients were discharged on the 14th and 21st postoperative days, respectively. CONCLUSIONS: Transoral stapling of the cervical anastomosis gave good results in two patients. More development and evaluation are needed.

The home treatment of deep vein thrombosis with low molecular weight heparin, forced mobilisation and compression.

BACKGROUND: The aim of this prospective study was to analyse a group of patients with DVT (deep vein thrombosis) treated at home with LMWH (low-molecular weight heparin), compression and intensive mobilisation and to evaluate its feasibility, efficacy and safety from possible risks of pulmonary embolism. METHODS: From March 1997 to September 1999, 96 consecutive patients with diagnosed DVT were enrolled in a prospective study and treated at home with enoxaparin (Clexane Rh ne-Poulenc) administered subcutaneously at doses depending on body weight (1 mg/kg) b.i.d. for a minimum of seven days. Oral anticoagulants were started two days before discontinuing LMWH and given later for three months according to the haemocoagulation parameters. All patients wore elastic second degree compression stockings during the whole period of treatment and for 12 months there after. They were encouraged to walk 1-3 km daily. The sites of thrombosis were ilio-femoral vein--38 patients (40%), femoral or popliteal vein--32 patients (33%), crural veins--26 patients (27%). According to our surgical criteria two years ago 17 patients would have been operated on and trombectomy performed. The diagnosis was made by compression ultrasonography using a colour duplex scanner (Acuscan 125), by contrast phlebography, and platelet scintigraphy (Tromboscint test). Perfusion-ventilation scintigraphy of the lungs was performed only if there were clinical signs or even a suspicion of pulmonary embolism and on all patients with iliofemoral thrombosis. Perfusion gamagraphy of lungs was carried out on 51 patients where thrombosis was localised in proximal veins. RESULTS: In 27 patients there were signs of non-fatal pulmonary embolism (53%), but only seven patients (26%) suffered mild non-specific clinical signs; 20 patients with diagnosed pulmonary embolism (74%) were symptom-free. Out of 96 patients, three admitted to hospital (3%), 67 (70%) injected LMVH themselves and felt comfortable. Eight to 12 weeks after this treatment control sonography and phlebography were carried out in 70 patients to assess the localisation and progress of the thrombosis. In 51% (36 patients) partial and 31% (22 patients) total recanalisation was found. Five out of 96 complained of minor bleeding (5%). No thrombocytopenia was noticed. The first five days on home treatment were crucial. All patients were able to walk and live at home without difficulty. None of our patients with proximal deep vein thrombosis used a vena cava filter. CONCLUSIONS: Home treatment of DVT is possible and is effective, safe and less costly on average and per patient 40% in costs was saved compared with those of a hospital stay in spite of the greater expense of LMWH. The patients who received LMWH spent a mean of 1.2 days in the hospital, as compared with 12.7 days for the standard-heparin group.

[True aneurysms of the popliteal artery--surgical treatment].

The authors discuss the history of treatment of popliteal aneurysm, causes of its development and its surgical treatment. They recommend surgery of an asymptomatic aneurysm with a diameter greater than 2 cm because of possible development of thrombosis with subsequent embolization into the periphery and development of gangrene of the extremity which may end by amputation. Early thrombolysis of a thrombotized aneurysm can be successful and combined with subsequent surgery can save the extremity. When a peripheral aneurysm is detected thorough surgical examination is necessary using ultrasonography, computed tomography and magnetic resonance resp. to detect aneurysms at other sites.

[Pathophysiologic aspects of chronic venous insufficiency].

Knowledge of the pathophysiology of the venous circulation and its evaluation before treatment determines not only the best therapeutic plan, but at the same time makes it possible to avoid operations which are not necessary and a priori doomed to lead to a relapse. The basic therapeutic principles in the treatment of chronic venous insufficiency after evaluation and localization of the functional disorder by an objective examination method (duplex sonography, phlebography ...) are: a) compression, b) severing of pathological points of insufficient perforators, orifices of both saphenous veins, c) antireflux operation of the deep veins with preference of the popliteal vein. Any therapeutic procedure which does not have the aim to reduce venous hypertension is a priori doomed to failure and very soon a relapse develops. From this aspect it is not important to remove chaotically and extensively superficial varicosities (surgically or by sclerotherapy) but to severe the insufficient perforators and the insufficient orifices of saphenous veins surgically or by sclerotherapy.

[Ambulatory treatment of deep venous thrombosis using low-molecular heparin, compression and mobilization].

From data in the literature as well as the authors' own experience ensues that diagnosed and objectively confirmed deep venous thrombosis can be successfully treated in out-patients departments by low-molecular heparin and compression with full mobilization without any major risk of pulmonary embolism and without the need of hospital admission (65 out-patients). Despite the high price of low-molecular heparin, treatment is economical as it does not require monitoring of haemocoagulation for hospital admission. Partsch et al. 1997 proved unequivoca lambda y that the rate of new attacks of pulmonary embolism during treatment is significantly lower than during classical treatment with non-fractionated heparin and immobilization.

[Anti-reflux surgery of the popliteal vein].

Any effective therapy of chronic vein insufficiency resides in the replacement or at least reduction of the pathological reflux causing venous hypertension. The aim of our study is to indicate the significance of the reconstruction of the damaged valves in the profound venous system, namely in the most critical popliteal area. On the basis of the experimental works of Wilson et al. (1991) we have introduced his technique of anti-reflux operation by the technique of invagination after the prolongation of the popliteal vein by three-fold average of its diameter by means of the axillary vein with a valve. This operation was performed in 6 patients on 7 veins. The operation lasted 3 hours in average without marked operative and post-operative complications. On the seventh day after operation, the full sufficiency is investigated by means of descendent phlebography in 5 newly formed valves and in two valves a particular insufficiency is developed. 4 patients yield a full recovery of ulcers, one patient slipped out from evidence, however sclerotisation of insufficient perforators leads quickly to recovery of dermal defects. Reconstruction of prothrombotically damaged valves is practically impossible and thus, valvuloplastic operation constructed from vascular wall in the target segment is not only possible but effective at the same time.

[Nutritional status in patients after reconstructive surgery of the upper digestive tract--status after 3 years].

The authors present an analysis of the nutritional status of eleven patients after reconstruction operations of the upper digestive tract (9 men and 2 women, aged 27-67 years, 7 times gastric resection, 4 times resection of the oesophagus), almost in all instances on account of malignant tumours. During the investigation the patients were given dietary advice incl. on the need of a higher vitamin and mineral intake. Three years after surgery the nutritional status of the investigated subjects did not change significantly as compared with the status before surgery but some trends were detected (decline of the serum calcium and albumin concentrations). Based on the results assembled in this small group the authors support views reported in the literature that reconstruction surgery of the upper digestive tract is safe as regards the patient's nutritional status.

[Compressive sclerotherapy monitored by ultrasound].

Echosclerotherapy and sonographic control of aimed sclerotherapy resp. is a major advance in the treatment of chronic venous insufficiency. It facilitates not only aimed administration of highly active substances but ensures above all prevention of serious complications. Functional examination of the venous system helps to locate relatively accurately the sites of pathological reflux which are in the first place responsible for the development of the whole symptomatology and it prevents the administration of excessive amounts of sclerotizing substances into intact portions of the venous system. Similarly as Baccaglini et al. (1995) the authors achieved by compressive sclerotherapy with monitoring by ultrasound occlusion of up to 90% important reflux sites such as the saphenofemoral and saphenopopliteal orifice which are to a great extent responsible for serious clinical symptoms.
