Psychological variables as predictors of the length of post-operative hospitalization.

The extent to which measures of anxiety and personality characteristics, which had been assessed preoperatively, could predict the length of hospital stay following surgery, above and beyond what could be predicted on the basis of biographical, medical-status and post-operative anxiety variables, was examined in 58 patients with gall-bladder disease. Hierarchical multiple regression analysis revealed that gender, previous operations, complications and State Anxiety (A-State) measured on the third day post-operatively, jointly explained a significant proportion of the variance in the length of hospitalization. Neither preoperative anxiety measures nor personality characteristics had any significant incremental value in the prediction.

[Relationship between perioperative anxiety and postoperative recovery].

One day before surgery and three days postoperatively, 118 cholecystectomy patients were investigated by means of several self-report anxiety-question(naire)s. On the basis of these, the patients were assigned to either the category more anxious postoperatively (A+) or the category less anxious postoperatively (A-). A+ patients rated preoperatively lower and postoperatively higher on the anxiety-question(naire)s than A- patients, and they stayed longer in hospital postoperatively.

Conservative versus operative treatment of displaced noncomminuted tibial shaft fractures. A retrospective comparative study.

The results of conservative (mainly, functional bracing) and operative treatment (mainly, plate fixation) have been compared in a retrospective study of 170 displaced noncomminutive tibial shaft fractures. The characteristics of the fractures in both treatment groups showed no significant differences. The follow-up analysis revealed no statistical differences in outcome between the two methods. However, because of the many factors analyzed and the restricted number of patients studied, it is impossible to compare all factors independently. Surgical treatment resulted in a higher rate of complications (such as implant failure, osteitis, and refracture) and a longer total hospitalization time. Conservative treatment showed a longer duration of fracture healing and a higher rate of malalignment. Malalignments of up to 10 degrees with no adverse effects have been seen so far. In conservative treatment, two fracture types were identified with a higher rate of malalignment: short oblique isolated tibial fractures and fully dislocated transverse crural fractures. Conservative therapy is favored, because there is less discomfort for the patient and the treatment is cost contained.

Diagnostic evaluation and survival analysis of colorectal cancer patients with liver metastases.

Clinical features and their prognostic value were evaluated in 83 colorectal cancer patients with liver metastasis. The clinical features analysed included presenting symptoms and signs, liver function tests, extent of liver involvement, associated extrahepatic tumor growth, and physical condition of the patients. Overall median survival time after diagnosis of liver metastases was 8.4 months. Prognostic factors related to survival were symptoms, when referable to liver metastasis, and 5' Nt. Information is supplied to survey what selection of patients should be considered for various treatment options. A predominance of the patients showed bilobar liver involvement (79.6%), extrahepatic tumor growth (49.4%), or had an unresectable primary tumor (30.1%), thus leaving only 6% of the patients with liver metastases for surgical treatment with the intention of cure.

An evaluation of routine follow-up for detection of breast cancer recurrences.

Four hundred patients who were radically treated for breast carcinoma during the period May 1974 to December 1980 were followed for a minimum of 4 years. The outcomes of the 128 patients with recurrences were studied. A differentiation into two groups was made: those in whom recurrences were detected as a real result of follow-up (27%) and those in whom this was not the case (73%). Both groups were comparable as regards age, period "at risk," nature and site of recurrence, type of therapy instituted, and their response to it. No differences could be found in any of these factors. The recurrence-free interval, the survival after institution of therapy, and the total survival after the primary procedure were the same in both groups.
