Our experience with 101 consecutive T.H.A.'s in 91 patients was examined in an attempt to identify preoperative risk factors for postoperative medical complications, especially pulmonary embolism and thrombophlebitis. Six per cent of patients developed postoperative clinical thrombophlebitis, and 8% a pulmonary embolism. Advancing age and previous venous thrombosis served as predictors for pulmonary embolism and thrombophlebitis, respectively (p less than 0.01), but obesity, venous varicosities, diabetes mellitus, cigarette smoking, previous pulmonary embolism, and length of surgery did not, for either. Fifty per cent of the patients with preoperative abnormal kidney function developed some form of medical complication postoperatively, a significant increase in risk (p less than 0.05) over patients with normal kidney function. We were unable to identify an increase in postoperative atelectasis or pneumonia associated with smoking or obesity in these patients. No consistent decrease in post-operative medical morbidity could be assigned to preoperative medical consultations, suggesting that we have not yet identified all significant risk factors. A thorough preoperative preparation and improvement in intra- and postoperative techniques and management may account for differences found in this study from traditionally held risk factors.

The most common pulmonary complication of EVS is pleural effusion. The most clinically significant pulmonary complication of EVS is delayed perforation with formation of esophagopleural or esophagobronchial fistula. Pneumonia, empyema, pulmonary infarction, and atelectasis can also occur. Endoscopic variceal sclerotherapy probably does not cause ARDS, but that issue remains unsettled. Transient relative pulmonary hypertension during EVS is probably of no clinical significance, but caution is urged when sclerosing varices in a patient with borderline right heart function.

Twenty-six stage II/III malignant melanoma patients with 321 measurable metastatic lesions were imaged using Fab fragments of an IgG murine monoclonal antibody labeled specifically with 10-30 mCi Tc-99m with a bi-functional chelating method (NeoRx, Seattle, WA). There were no side effects or adverse reactions. Immunoscintigraphy demonstrated 66.6% of lesions larger than 1 cm and 92.5% of lesions larger than 3 cm. Most frequently detected metastases were in lymph nodes, subcutaneous areas, and bone. Of lesions less than 1 cm, 23.6% were detected if superficial cutaneous lesions were excluded. The smallest detectable lesion was 4 mm. Twenty-one additional clinically unsuspected sites were visualized in 12 of the 26 patients studied. Of these, 56% were confirmed as metastasis by other tests. There were apparent nonspecific localizations owing to other causes, including fracture, varicosities, skin abscess and pneumonitis. Increased experience in image analysis facilitates correct interpretation of these localizations. This study demonstrates that imaging with Tc-99m labeled antibody fragments detects melanoma lesions in organs routinely surveyed and in other areas not routinely assessed by other imaging techniques. The procedure is readily performed and safe. The principal advantage of the test is its ability to survey the entire body and all organs with a single test. Its principal limitation, in common with other diagnostic imaging procedures, is its poor sensitivity for detecting lesions less than 1 cm.

The authors report their 2-year experience of esophageal endoscopic sclerotherapy for prevention of recurrent variceal bleeding in patients with liver cirrhosis. Sixty-three alcoholic cirrhotics underwent sclerotherapy 10 +/- 6 days (SD) after hospital admission for variceal bleeding. Varices were successfully eradicated in 43 patients (68 p. 100), with an average of 3 injection sessions, over a mean period of 5 weeks. Unsuccessful treatment was due to abbreviated course of treatment because of early rebleeding and early mortality. Early rebleeding episodes after therapy occurred in 19 patients (30 p. 100): 10 in whom the esophageal varices were eradicated, 9 in whom sclerotherapy had failed. Recurrent hemorrhage was the cause of death in 6 patients. After variceal eradication had been achieved, new varices were observed in 7 p. 100 of patients after a mean follow-up of 8 months. The risk of further variceal bleeding was 0.008 hemorrhage/patient/month. Minor complications (thoracic pain, dysphagia, esophageal ulcers, pleural effusion) occurred in 60 p. 100 of patients. An esophageal stricture developed in 13 out of the 43 successfully treated patients (30 p. 100). Major complications occurred in 5 patients and was the cause of death in 4: mediastinitis, esophageal perforation, bronchoesophageal fistulae, cardiogenic shock and aspiration pneumonitis. The survival curve, assessed by cumulative life analysis, showed a 60 p. 100 survival rate after 12 months and 56 p. 100 after 18 months. It was significantly different (p less than 0.001) between groups of cirrhosis classified according to Child-Pugh's criteria (95, 52 and 9 p. 100 at 12 months for groups A, B and C respectively).(ABSTRACT TRUNCATED AT 250 WORDS)

Thirteen patients with acute or recent bleeding from gastro-oesophageal varices were treated by sclerotherapy using flexible fiberoptic endoscope. Primary haemostasis was obtained in 10 of 11 admissions with active bleeding. Three patients have been treated for gastric varices with the same method. Such treatment has not been reported before. During the follow-up period, three patients died, two of variceal haemorrhage and one of pneumonia. Ten patients are still alive 2-53 months after the first admission. A total of 117 treatment courses were given, on an average 9 per patient. Complications included superficial mucosal necrosis without clinical consequences in several cases, 3 patients developed oesophageal and gastric ulcers and one moderate oesophageal stenosis. Rebleeding occurred in 4 patients, in 2 of them because of ulcers at the sites of injections.

The objective of this study was to describe the health problems of a group dementia patients on admission and during residence in a Dutch nursing home and to compare these with figures of patients of 75 years and over from general practice. In 890 nursing home patients suffering from dementia prevalence of health problems on admission and the incidence during the residence were classified by means of the ICHPPC-2-defined. The differences between men and women were studied as was the influence of the season on the incidence during the stay. Results were compared with figures of patients of seventy five year and over from the continuous morbidity registration (CMR) from 'Nijmegen'. The most frequently occurring health problems on admission were: varicose veins of legs, acquired deformation of the spine, presbyacusis, hypertension, arthrosis, COPD, cerebrovascular disorders, heart murmur, cataract and chronic ischemic heart disease. During the residence the following health problems were frequently diagnosed: urinary tract infection, side effect of medicine, constipation, pneumonia, pressure sore, feeding problem, contusion, heart failure, cold and conjunctivitis. There were clear differences between men and women. Especially the incidence of intercurrent diseases showed great differences from the patterns in general practice. Prevalence of health problems on admission to the nursing home home agreed mor with figures from general practice. Respiratory tract infections frequently occurred in winter and urinary tract infections, pressure sores and conjunctivitis seemed to occur more in the summer. Nursing home patients with dementia have a lot of chronic and intercurrent health problems. They differ clearly from patients in general practice.(ABSTRACT TRUNCATED AT 250 WORDS)

Twelve consecutive patients admitted for bleeding from ruptured gastric varices were treated with transjugular intrahepatic portosystemic shunts and followed for a mean of 6 +/- 3 months (range: 8-293 days). The shunt was performed successfully in all 12 patients. The shunt occluded in 3 patients (respectively 19, 101 and 103 days after insertion) of whom one remained asymptomatic and two experienced rebleeding. Four patients presented with acute encephalopathy, spontaneously in two and after rebleeding in two. Three patients died, two after rebleeding and one of septic shock secondary to pneumonia. Overall, 9 patients survived a mean of 211 +/- 92 days with no rebleeding, 8 of whom have not yet experienced any complications. These results suggest that transjugular intrahepatic portosystemic shunts could be useful in treating hemorrhages from ruptured gastric varices and in preventing their recurrence.

A 45-year-old alcoholic male patient presented with hypovolemic shock and intense anemia (Hemoglobin 04.7 g/dl), and was operated on. A bleeding retroperitoneal varix located near the right colon was responsible for the clinical picture and was sutured. After operation the patient developed haemodynamic instability and pneumonia a situation which was reverted with intensive medical therapy. The patient is now doing well.

Endoscopic variceal ligation has emerged as a superior alternative to endoscopic injection sclerotherapy, however, the "single-shot" mechanism of the generally used Stiegman-Goff ligator made the procedure tedious and time-consuming and required overtube placement, associated with discomfort and potentially life-threatening complications. In this study we describe our experience with the Saeed Six-Shooter (multiple-ligation device). Fifty consecutive patients with variceal bleeding were prospectively studied. After initial endoscopic ligation, subsequent sessions were every 2 weeks. Study outcomes were: the ability to control active bleeding, the frequencies of rebleeding, the number of treatment sessions and time required for irradication, the percentage eradication of varices, complications, and mortality. Active bleeding was controlled in all eight (100%) patients. Four (8%) patients rebled, three from esophageal varices, and one from portal hypertensive gastropathy. Esophageal varices were eradicated in 47 (94%) patients (3.1 +/- 1.3 sessions). Time needed till eradication was 6.2 +/- 1.9 weeks. Chest pain was reported in two (4%), low, grade pyrexia in two (4%), and pneumonia in one (2%) patient. There were three deaths, none due to exsanguination. The Six-Shooter is a safe and efficient device for the endoscopic ligation of esophageal varices which has overcome the limitations of the single-shot ligator: (1) Visualization is better (the endoscopic "tunnel vision" and internal light reflection from the stainless-steel banding cylinder of the single-shot device are avoided); and (2) the use of an overtube is no longer necessary and serious complications can be avoided.

Intestinal microflora plays an important role in the pathogenesis of hepatic cirrhosis (HC) complications. These patients are at a high risk of bacterial infections, mainly spontaneous ascitis infection or spontaneous bacterial peritonitis, pneumonia, or pleural empyema. Other HC complications, such as varicose vein hemorrhage, gastropathy, hepatorenal and hepatopulmonary syndromes, and portopulmonary hypertension, develop mainly due to portal hypertension. Portal hypertension is primarily caused by increased intrahepatic resistance, while after the forming of collateral circulation high portal pressure is maintained by increased splanchnic blood inflow secondary to vasodilatation. Itraorganic vasodilatation initiates hyperdynamic circulatory status, which exacerbates HC complications. Intestinal microflora plays a role in the development of both infectious complications and hyperdynamic circulatory status in HC. The article contains evidence of the influence of intestinal microflora on the development of HC complications.
