Lung biopsy using harmonic scalpel: a randomised single institute study.

OBJECTIVE: Applicability of harmonic scalpel in lung biopsy was investigated in a randomised single institute study. METHODS: Safety of the method, morbidity, drainage duration and in-hospital stays were compared in two randomised groups of patients in which either ultrasonic harmonic scalpel (n:20) or endostapler (n:20) were used for pulmonary biopsies during VATS. RESULTS: An advantage of 16min in average operation time was found in favour of the harmonic scalpel (30.75 vs 46.9min) which was significant. There were no differences in average drainage duration (40.2 vs 30.6h) and pleural fluid volume (258 vs 232ml). Minor complication rates (3 vs 3) were identical and in-hospital stays (7.6 vs 7.2 days) were also similar. CONCLUSIONS: Overall, the vibration transmission method was shown not to be inferior to the standard endostapling technique. A safe new method offers an alternative technique for peripherial lung biopsy.

Cutting lung parenchyma using the harmonic scalpel--an animal experiment.

OBJECTIVE: Applicability of harmonic scalpel in lung surgery was investigated using an animal model. METHODS: Air tightness, control of bleeding and features of tissue regeneration were compared in a 4-week time frame of investigation in animals in which either surgical stapler or harmonic scalpel were used for pulmonary resection. RESULTS: No significant differences between the two methods were found on a clinical and histopathological basis. CONCLUSIONS: Complete lack of granuloma formation at the resection line and in its vicinity consequently restitutio ad integrum demonstrate the advantage of the harmonic scalpel over the stapler in the circumstances investigated. Overall the vibration transmission method was shown not to be inferior to the standard methods in peripheral lung tissue resection.

Long-term follow-up results of surgery for chronic pancreatitis.

BACKGROUND/AIMS: Based on a mean follow-up period of 86 months, the long-term results of 87 drainage and resection operations performed for chronic pancreatitis between 1990-94 were evaluated. METHODOLOGY: To evaluate the results, two questionnaires were filled out by the patients. The first was related to the pancreatitis and the long-term complications, the second was a Gastrointestinal Quality of Life Index questionnaire. Data of deceased patients were collected with the help of general practitioners. RESULTS: Based on the analysis of disease-related and quality of life questionnaire forms only 34% of the investigated patients could be classified as a group showing good results. There was a high incidence of long-term mortality (25%). Eighty-three percent of the deceased patients (18 patients) died after the seventh postoperative year. The most threatened group seems to be the alcoholic and insulin-dependent diabetic one. The combination of the two pathologies was the cause of death in a third of the cases. Insulin-dependent diabetes mellitus developed in 13 patients after an average of 3.9 years following surgery, mainly as a consequence of the irreversible and progressive nature of disease. The rate of disability was 51%. No significant difference could be demonstrated between the resected and the decompressed group according to either disability or late mortality rate. CONCLUSIONS: Based on these results, the authors wish to emphasize that in chronic pancreatitis the short-term follow-up results may be deceptive, and that the real outcome of the surgical treatment can only be expected five years following surgery.
