Primary solitary tuberculosis of the liver.

Primary solitary tuberculous involvement of the liver is a rare condition. We present the case of a patient who was operated on with a preoperative diagnosis of hepatocellular carcinoma. Liver resection was performed and antituberculous therapy was started. It is difficult to make the correct diagnosis preoperatively except when a successful needle biopsy can be performed. Despite the rarity of the condition primary solitary tuberculosis should be considered among the space occupying lesions of the liver.

Villous tumors of the duodenum.

Two patients with villous adenomas in the duodenum are described. These lesions have a predilection for the ampullary region, and tend to present with obstructive jaundice, especially if malignancy is present. The first patient, with a villous adenoma located at the ampulla of Vater, presented with jaundice and underwent pancreaticoduodenectomy at a second operation because of a high rate of false-negative biopsies. The second patient was admitted with partial mechanical obstruction symptoms and was treated by partial duodenectomy and antrectomy for a supraampullary villous adenoma, including in situ carcinoma.

Incidence and prognostic significance of intraventricular conduction abnormalities after coronary bypass surgery.

To determine the incidence and prognostic significance of new postoperative conduction disturbances, 2,000 consecutive patients who underwent primary elective coronary bypass surgery were evaluated. One hundred eleven (5.5%) of the 2,000 patients developed a new intraventricular conduction defect that persisted to hospital discharge. Right bundle branch block occurred in 86 (85%), left bundle branch block in 5 (4%) and nonspecific intraventricular conduction defect in 9 (11%). One hundred of these 111 patients were successfully matched with others in the study population who had maintained normal intraventricular conduction during the operative period. Patients were matched on the basis of age, gender, absence of preoperative conduction disturbances, left ventricular function and bypass grafts to the same vessels. Follow-up of the two groups for a period of 1 to 76 months (mean 60 months) failed to show any difference in survival or cardiac events such as myocardial infarction, repeat coronary bypass surgery, coronary angioplasty and permanent pacemaker implantation. The appearance of right or left bundle branch block or a nonspecific intraventricular conduction defect after coronary bypass surgery does not appear to have an unfavorable impact on the long-term prognosis of these patients.

Hydatid cysts of liver and portal hypertension.

Two cases of portal hypertension due to hydatid cysts of the liver are reported. In one of the patients, symptoms were secondary to obstruction of inferior vena cava and hepatic outflow tract. The other patient was operated on with a diagnosis of extrahepatic presinusoidal portal hypertension caused by extrinsic compression of the liver by an hydatid cyst. Although hydatidosis is a benign disease, it can produce serious complications as in these reported cases. Therefore hydatidosis should be remembered amongst the causes of portal hypertension in countries where the disease is endemic.

Introflexion as a method of surgical treatment for hydatid disease.

For the management of the residual cavity after removal of a hydatid cyst, several surgical methods have been suggested. To prevent the undesirable results of the previously suggested techniques, we have been using a new method called introflexion. This simple, safe and effective method has been described and discussed herein.

Treatment of liver hemangiomas by enucleation.

Nine patients with hemangiomas of the liver were treated by enucleation between 1976 and 1985 at the Surgical Department of Istanbul (Turkey) Medical School. The tumors were removed by dissecting the plane between the capsule of the hemangioma and normal liver tissue. The diameters of the tumors ranged from 8 to 23 cm. There was no mortality and no massive bleeding. It is suggested that hemangiomas can be removed by an enucleation technique with low mortality and morbidity, rather than by liver resection.

Choledochoduodenostomy for intrabiliary rupture of hydatid cysts of liver.

Frank intrabiliary rupture is an important complication of liver hydatid cysts and its incidence is between 5 and 25 per cent. The main principles of management are the surgical treatment of the cyst with removal of all cystic elements and drainage of the biliary tree. Accurate pre- and intra-operative diagnosis and permanent drainage of the biliary tree by a wide choledochoduodenostomy are important to reduce morbidity and mortality. In this report 28 cases of frank intrabiliary rupture of hydatid cysts treated by choledochoduodenostomy are presented.

[Blunt abdominal injuries in childhood (author's transl)].

Traffic accidents are among the most important causes of child death. It is sometimes quite difficult to diagnose blunt abdominal traumata due to traffic accidents. 35 blunt hepatic and splenic injuries treated in our clinic during the period of 1971 to 1976 have been evaluated and pertinent references reviewed.

Atrial pacemaker leads compared.

In order to analyze the impact of different polarity and electrode designs on the acute pacing and sensing characteristics of pacemaker leads, 80 patients with complete heart block or sinus node dysfunction undergoing pacemaker implantation received eight different leads from five manufacturers. Once the leads were positioned, volt and current thresholds, P wave, peak-to-peak, and slew rate were assessed prospectively. There was no statistically significant difference between acute pacing thresholds, sensing characteristics, or unipolar and bipolar pacing thresholds. Active fixation leads allow atrial mapping and lead placement in areas generally inaccessible to tined tip leads. This is an advantage, especially for patients with a history of open heart surgery.
