Flushable exo-endodrainage: a modified palliative approach to non-resectable malignant biliary obstruction.

The introduction of new imaging techniques has markedly improved the diagnosis of hepatobiliary disorders. Due to their anatomic situation, a substantial percentage of malignancies located near the hilus is not suitable for surgical management. We discuss an effective palliative intervention to relieve jaundice. In many instances drainage is a superior choice when biliodigestive anastomoses are not technically feasible and palliative resection carries a high complication rate. We present an irrigatable exo-endodrainage method employing a modified port-a-cath system as a new alternative. In four patients, all older than 75 years, this system was implanted because of jaundice due to unresectable malignant stenosis of the extrahepatic bile duct. One patient (80 years old) died of pre-existing acute necrotizing pancreatitis, although hyperbilirubinemia was found to decrease on the 7th postoperative day. The other three patients showed complete normalization of their bilirubin levels and their port-a-cath systems remained open until their death (at 3 weeks, 6 months and 7 months respectively).

Determination of placental ferritin-positive peripheral lymphocytes in early stages of breast cancer.

"Ferritin-blocked lymphocytes" or placental ferritin (PLF) -positive T cells have repeatedly been described in the circulation of patients with female breast cancer. Since a monoclonal antibody directed against PLF became available, a study was performed to evaluate its usefulness in an easily reproducible system. One hundred patients with controversial or highly suspicious findings on mammography who subsequently underwent operation entered this trial. Sixty-one healthy blood donors served as controls. Patients with early (lymph-node negative) stages of breast cancer (in situ and T1N0 tumors) revealed significantly higher numbers of PLF-positive cells (9.00% +/- 4.5% and 6.21% +/- 3.4%) as compared with controls or patients with benign lumps (p < 0.001). Patients with negative lymph nodes differed significantly from node-positive patients (9.79% versus 2.55%; p < 0.001), whereas no difference as related to menopausal and estrogen-receptor status was observed. In order to define the sensitivity and specificity of this test, we analyzed four different cutoff levels (3%, 4%, 5%, and 6% of PLF-positive T cells). At a level of PLF-positive lymphocyte cells of 4%, 94% of cancer patients with stage T1N0 disease or ductal carcinoma in situ, 5% of patients with benign lumps, and 7% of healthy controls were identified. Furthermore, 88% of all lymph node-negative cancer patients had more than 4% positive cells, compared with only 25% in patients with axillary node involvement. The fact that more than 90% of all patients with in situ carcinomas and patients with stage T1N0 cancer had values above 4% offers promising aspects for this method to be used to complement mammography in the early detection of breast cancer.

Local gentamicin application for perineal wound healing following abdominoperineal rectum excision.

A major complication of abdominoperineal rectum excision for rectal or anal carcinoma is local wound infection. The main reason for this infection is that systemically administered antibiotic prophylaxis does not reach sufficiently high concentrations of antibiotic in the tissue of the sacroperineal wound. Since gentamicin-polymethylmethacrylate (PMMA) in the form of chains of beads has been confirmed as a useful tool in the treatment of local infection in bone and soft tissue surgery, we have evaluated its effect on the abdominoperineal rectum excision in a prospective, randomized trial. Forty-four patients with rectal or anal carcinoma entered the study. Only patients with stage Dukes D were excluded from the trial. Following randomized selection, the patients were treated either with local gentamicin and drainage (Group A) or drainage alone (Group B), using the Lloyd-Davies procedure. The two groups were comparable regarding age, sex, tumor stage and level, and risk factors predisposing for an infectious complication (anemia, nutritional status, blood transfusion). The postoperative mortality rate was 0% in both series. Analysis of local perineal wound healing revealed a statistically significant higher percentage of primary wound healing in Group A than in Group B (87% versus 46%; p less than 0.01). This led to a significantly shorter hospitalization period for patients in Group A (p less than 0.01). Gentamicin-PMMA chains have been demonstrated to exert a favorable effect on local wound healing and the postoperative outcome of patients with abdominoperineal rectum excision.

[Breast cancer in the male--a retrospective analysis of 15 cases]. / Mammakarzinom beim Mann--Eine retrospektive Analyse von 15 Fällen.

We report about 15 cases of cancer of the male breast treated within the period 1972-1988 at the Surgical Department of the Hanusch-Krankenhaus, Vienna. Patients age ranged from 38 to 82 years, averaging 61.7 years. After a median follow-up period of 40 months (ranging from 1-171 months) two-thirds of our patients had died, 40% from the primary disease. In cases with a follow-up period of more than 5 years, only 1 out of 11 patients is still alive, 6 of them having died in the meantime. In 40% of our patients the first symptom noticed was a painful lump accompanied by gynecomastia. Seven patients out of 15 (i.e. 46.6%) had been treated previously with aldosterone antagonists of spironolactone type. Except for 1 patient who had had X-ray radiation in the past, no other exposure to possible risks could be observed. A multicentre data input and central processing of generic data for the evaluation of optimal treatment of this rare disease is desirable.

[Consecutive series of 100 colonic resections with a modified continuous suture technic]. / Konsekutive Serie von 100 Colonresektionen mit einer modifizierten fortlaufenden Nahttechnik.

Based on a consecutive series it is reported about a modified type of "continuous" suture on the colon, used especially in elderly patients for being a secure and prompt method of anastomosing. The rate of insufficiency and mortality, as far as the clinical relevance is concerned, turns out to be 2% each and there was no relation between mortality and insufficient anastomosis. The complication rate was 11%, whereby the urological complications predominated with 6% of the total.
