Surgical treatment of intrabiliary rupture of hydatid cysts of liver: comparison of choledochoduodenostomy with T-tube drainage.
BACKGROUND: Intrabiliary rupture is one of the most serious complications of liver hydatid cysts (LHC). The kind of surgery for these patients is still controversial. T-tube drainage and choledochoduodenostomy (CD) are used by most of the surgeons. But there is no comparative study in the literature. METHODS: Eighty patients with symptomatic intrabiliary rupture were treated between 1980 and 1995. All patients had jaundice. In addition to treatment of the cyst cavity, T-tube drainage of the common bile duct (CBD) was performed in 53 patients, 25 patients underwent a CD for biliary drainage and two patients were treated by a T-tube placed in the CBD without treating the cyst. The T-tube drainage and CD groups were compared in regard to morbidity, mortality, duration of the operation, rate of relaparatomy and duration of postoperative hospital stay. RESULTS: The morbidity rate was 40% (10/25) after CD and 18.1% (10/55) after T-tube drainage. Relaparatomy was necessary in 8% (2/25) and 1.8% (1/55) of patients treated with CD and T-tube drainage, respectively. T-tube drainage was performed much more rapidly than CD (p < 0.05). The length of hospital stay for both groups was the same. One patient who was treated with CD died postoperatively. CONCLUSION: Our results suggest that T-tube drainage is superior to CD for intrabiliary rupture of LHC in most cases.

Sister chromatid exchange rate from pleural fluid cells in patients with malignant mesothelioma.
This study assessed the impact of malignant mesothelioma on the frequencies of sister chromatid exchange (SCE) in the pleural effusion cells. Ten patients with mesothelioma and 20 control subjects were included in the study. The control subjects were the patients with tuberculosis pleurisy, and the remaining 10 subjects of control group were healthy volunteers and only heparinized blood samples were collected from these subjects. The pleural effusion cells were cultured with conventional culture methods. The samples were obtained from the patients after histopathologic confirmation of the malignancy but before the initiation of chemotherapy or radiotherapy. At the end of the culture period and 48 h prior the harvesting, BrdU was added into flasks. Totally, 100 metaphases were scored for each sample. In this study, we found that the SCE frequencies of malignant pleural mesotheliomas were significantly higher than the control subjects (P<0.001). Six of 10 patients came from central Anatolia, which is of great importance due to high rate of exposure to asbestosis in this region.

Beneficial effects of iloprost during experimentally induced hemorrhagic shock.
BACKGROUND: The aim of the study was to evaluate the efficacy of iloprost on myocardial insufficiency associated with hypovolemic shock in dogs. We designed the study as a controlled randomized study. METHODS: Sixteen mixed-breed dogs were included into the study and divided into two equal groups as the control and iloprost groups. Mean arterial pressure was reduced to 45 mmHg by withdrawing the arterial blood into citrated bags. The control group did not receive any drug but the other group received iloprost at a rate of 20 ng/kg/min by an infusion pump. Iloprost infusion was started 30 min after the blood pressure was reduced to 45 mmHg. All measurements were made before removal of blood, 45 min after exsanguination and at 1 hour intervals for 3 hours. Left ventricular stroke work index was measured 72 hours after the study. The hemodynamic and biochemical parameters and blood gas analysis were obtained. RESULTS: After hemorrhage, cardiac index (CI) decreased significantly from 132 +/- 14 to 51 +/- 8 ml/kg/min in the control group and from 128 +/- 11 ml/kg/min to 47 +/- 13 ml/kg/min in the iloprost group, respectively but at the end of the third hour it was 81 +/- 8 ml/kg/min in the control group and 105 +/- 6 ml/kg/min in the iloprost group (p < 0.05). Tumor necrosis factor-alpha (TNF alpha) was 41 +/- 8 pg/ml in the control group and 18 +/- 6 in the iloprost group 3 hours after bleeding (p < 0.05). Tumor necrosis factor-alpha concentration was significantly higher in the control group than in the iloprost group. There was no significant difference in pH between the groups but actual bicarbonate concentrations were different between the groups (p < 0.05). At the end of the third hour total body oxygen consumption was 105 +/- 11 ml/min in the control group and 132 +/- 12 ml/min in the iloprost group (p < 0.05). Oxygen delivery 3 hours after hemorrhage was 201 +/- 19 ml/min in the control group and 252 +/- 24 ml/min in the iloprost group (p > 0.05). Left ventricular stroke work index was higher in the iloprost group (p < 0.05). CONCLUSIONS: Hemorrhagic shock causes tumor necrosis factor-alpha release which may lead to multiple organ failure. Organ dysfunction still persists even after the appropriate treatment. Iloprost attenuates the release of tumor necrosis factor-alpha which may improve the adverse effects of hemorrhagic shock.

Myocardial hemodynamic and metabolic changes during abdominal insufflation with carbon dioxide.
It is a well-known fact that laparoscopic procedures performed with carbon dioxide insufflation impair myocardial function. In this study, we aimed to determine the safety limitations of various intra-abdominal pressure values during abdominal insufflation with carbon dioxide. Of the 24 mongrel dogs, 6 were assigned to one of four different pressure groups (10, 15, 20 and 30 mm Hg), respectively. Cardiac output, right/left heart pressures, and the first derivative of ventricular pressure were monitored. Myocardial oxygen consumption, myocardial lactate/oxygen extraction, tissue lactate and adenosine triphosphate levels were determined. Measurements were performed initially as a control, at 15-min intervals during 1 h of insufflation and 1 h after desufflation. At 10 mm Hg carbon dioxide pressure, hemodynamic and metabolic parameters were not significantly different. Cardiac output decreased significantly in the 20 and 30 mm Hg groups (p < 0.05: 10, 15 vs. 20, 30 mm Hg). Although cardiac output did not change at 15 mm Hg, the dp/dt value was significantly reduced. Cardiac output at the 60th min was 1,960+/-75 ml/min in the 10 mm Hg group, 1,885+/-40 ml/min in the 15 mm Hg group, 1,770+/-45 ml/min in the 20 mm Hg group and 1,695+/-40 ml/min in the 30 mm Hg group. Myocardial oxygen consumption was reduced at 15, 20 and 30 mm Hg (p < 0.05: 10 vs. 15, 20 and 30 mm Hg). In the myocardial tissue, ATP decreased from 19+/-2 to 12+/-1.2 micromol/g at 15 mm Hg, from 19+/-1.9 to 9.4+/-1.3 micromol/g at 20 mm Hg and from 18+/-3.2 to 8.2+/-1.9 micromol/g at 30 mm Hg. Changes in hemodynamic and metabolic parameters of the heart are reversible and may not lead to any significant impairments in patients having normal cardiopulmonary function, but pose a risk in patients with respiratory disease and limited myocardial reserve.

Caroli's disease: 1977-1995 experiences.
OBJECTIVE: Until recently, congenital cystic dilatation of the intrahepatic biliary ducts (Caroli's disease) has been recognized infrequently. This report aimed to analyse and discuss our observations on 21 adult patients with the disease. PATIENTS: From 1977 to 1995, 21 patients (eight women and 13 men), aged 17 to 68 years, were diagnosed and treated for Caroli's disease at Yuksek Ihtisas Hospital. The mean duration of the disease was 6.5 years. RESULTS: The commonest presenting symptom was abdominal pain, a feature in 18 cases. The distribution of the biliary lesions was bilobar in 12 patients and monolobar in nine. Two of them were congenital hepatic fibrosis. Twenty-one patients had coexisting hepatobiliary disease, associated with Caroli's disease. Approximately 95% of our patients had cystolithiasis, cholelithiasis or both. Surgical treatment was used in 18 patients, a partial hepatectomy being carried out in seven of them, an internal biliary drainage by choledocystojejunostomy in five cases, and by choledochotomy in four cases. Three cases with Caroli's disease were treated with endoscopic sphincterotomy and stone extraction. In the follow-up period, four of our patients died. CONCLUSION: Caroli's disease is being diagnosed more frequently as a result of improved diagnostic capabilities. The aim of the treatment is to obtain sufficient biliary drainage and to relieve the symptoms.

Surgery for hydatid cysts of the liver.
This report details the perioperative management of 488 patients who underwent surgery for hydatid cysts of the liver. The most common pathology was a single cyst in the right lobe of the liver (53%). The preferred surgical procedures were partial cystectomy with closure of the residual cavity by suturing (31%) and total cystectomy (18%). Communication with the biliary system was found in 13% of cysts. The presence of multiple cysts and the need for additional procedures contributed to the overall perioperative morbidity (42%) and mortality (1%).

Intussusception due to inflammatory fibroid polyp of the ileum. A report of two cases from Turkiye.
Intussusception due to inflammatory fibroid polyps is a very rare entity. In this article two cases of inflammatory fibroid polyps of the ileum (A 32-year old man and a 50-year old woman) in Turkiye are described. Both patients were admitted to the hospital because of acute intestinal obstruction as a result of an intussusception caused by a polyp. The lesions were characterized by an eozinophil containing loosely structured fibrous tissue comprising an onion-skin like arrangement of reticular fibers with spindle-shaped nuclei localised in the submucosa and the base of the mucosa, and variable proliferation of fibroblasts and small vessels. The aetiology of these polyps remains obscure but they appear to be a reactive process (allergic or foreign body reaction) rather than neoplastic. Nkanze et al reported 12 cases of intussusception due to fibroid polyps in Africa. Our two cases are the first cases in Turkiye.

Human fascioliasis.
Infestation with fasciola hepatica is not often seen in humans. Only a few cases have been reported previously, while in our clinic only three cases have been observed in 20 years. All three cases (two males aged 35 and 40 and a 45-year-old female) were operated on with the possible diagnosis of choledocholithiasis, and parasites were later incidentally discovered at operation. In recent years praziquantel has been used with a high rate of success in the medical treatment of this disease. We have also prescribed praziquantel for our last two cases in order to prevent recurrence and to kill any parasites that might still remain after the operation. In the post-operative follow-up a complete cure was observed in all cases.
