[Endoscopic palliation of malignant esophageal stenoses].

The choice of the appropriate endoscopic procedure for treating a malignant esophageal obstruction depends on the tumor localisation, the tumor configuration, on specific patient data and last but not least on the technical possibilities of the hospital involved. Successfully performed is the mechanical dilatation, the tube insertion and stent implantation, the laser therapy, the argon plasma coagulation and the local sclerotherapy. The procedures differ in rate of complication, long term palliation and the improvement of dysphagia. In a case discussion we demonstrate that in the wide range of disease and patient specific facts that have to be dealt with, only the combined use of different endoscopic procedures will lead to the best results.

[Benign pleural mesothelioma. Report of 2 cases].

We report two cases of benign pleura mesothelioma. We compare our pre-, intra- and postoperative findings with other reports in the literature. This tumor is rare. The patients have few symptoms. Large tumors may cause hypoglycemia. The treatment of choice is complete resection of the tumor. The prognosis is good.

[Clinical aspects and therapy of Boerhaave syndrome].

We report of a case of spontaneous rupture of the Oesophagus (Boerhaave's-Syndrome) from a 56 year old female alcoholic, who was soon operatively treated. First the patient was explored by a left thoracotomy, the rupture was sutured from abdominal and butressed with the gastric fundus and a feeding jejunostomy was established. Because of postoperatively complications the patient was treated with haemofiltration. The way was prolongated because of severe obstructive airway disease, the patient left intensive care after 22 days.

[Glomus tumor--a rare stomach tumor].

We report on a 72 year old woman with a large glomus tumor of the stomach is given. The difficulty of preoperative diagnostics is described, and the importance of immediate section of microscopic examination during surgery in order to minimize the extent of resection is shown. Gastric glomus tumors are rare, benign, and normally solitary lesions in the antrum or pyloric region. When the exact intraoperative diagnosis is possible, a local excision is seen as a sufficient treatment.

[Mesenteric panniculitis].

We report three cases of mesenteric panniculitis in which the disease took different courses. The first case clinically mimicked an acute diverticulitis and consequently laparotomy was performed. During this operation a large space-occupying tumour was found in the lower abdomen. After resecting this tumour mass of uncertain classification (benign or malignant) a preternatural anus of sigmoid colon was formed. Histological exploration revealed mesenteric panniculitis. Six months later we restored continuity of large bowel by end-to-end anastomosis. No residues of the preexisting panniculitic alterations were seen. The second case concerned a female patient who again complained of discomfort after surgical treatment of colon carcinoma. We measured an elevated erythrocyte sedimentation rate and suspected a relapse of the malignant disease. Notwithstanding radiological and endoscopic diagnostics, the origin and classification of an intra-abdominal tumour could not be determined preoperatively. Laparoscopically we took a biopsy of the local mass, but a definite diagnosis was not found. Postoperatively undulant fever occurred, uninfluenced by cortisone treatment. Finally the patient died because of unstoppable hemorrhage under coagulopathy. Mesenteric panniculitis was identified as causative disease by autopsy.

[The Askin tumor].

The Askin tumor, a primitive malignant small-cell tumor of the chest wall, is mostly seen among children and adolescents. It is closely related to Ewing's sarcoma of the same location, both tumors showing a chromosomal translocation t(11;22). Its origin from neuroectodermal cells is deducted from several ultrastructural details and from the expression of specific markers like NSE. Pain and deformation of the chest wall are the cardinal clinical signs of the tumor. Chest X-rays will frequently show destruction of ribs and pleural effusions. Effective therapy consists of radical surgery, local radiation and adjuvant chemotherapy. This multimodal concept allows minority of patients to remain disease-free but the overall outcome is rather unfortunate.

[Argon gas embolism in laparoscopic cholecystectomy with the Argon Beam One coagulator].

The report is about argon embolism in a 37-year-old female patient during laparoscopic cholecystectomy and coagulation of a liver bed bleeding with the "Argon Beam One". The presented case report is to show that in spite of technical perfection and correct use of the Argon Beam One coagulator unfavorable anatomical conditions can cause life threatening gas embolism.

[Can endoscopic methods decrease the mortality and complication rate of bleeding stomach and duodenal ulcer? A study of the literature].

Bleedings from gastroduodenal ulcers still pose a major threat to health and life of a patient. Recent technical developments have provided the endoscopist with several methods for achieving hemostasis. In the present paper the results from clinical studies concerning interventional endoscopy shall be discussed. Criteria for the therapeutic approach for an individual patient shall be presented. Optimal results are possible if diagnosis and initial treatment are handled quickly by an experienced endoscopist. Early cooperation with the surgeon will further improve the outcome.

[Chronic reflux esophagitis with endobrachyesophagus and multifocal adenocarcinoma].

In approximately 10% of all cases of endobrachesophagus a malignant degeneration occurs. A frequent endoscopic and bioptic control of the endobrachesophagus is the prognostic decision in order for a developing adenocarcinom to be identified in the early stages. Our casuistry demonstrates the problematic nature of the diagnostic and therapy of a multifocal adenocarcinom in an endobrachesophagus.

[Gastrointestinal leiomyosarcoma].

The clinical course of 12 patients was analyzed in a retrospective study; all of these patients were operated on a gastrointestinal leiomyosarcoma. The most common site of metastasis was the liver (33%). These data confirm that histologic grade, size and the extent of resection are the most important prognostic factors. Because the differential diagnosis between benign and malignant smooth muscle tumors is often quite difficult and a high risk of local recurrence the enucleation of these tumors is insufficient.

[Primary non-Hodgkin lymphoma of the stomach: diagnostic and therapeutic procedure].

It is reported on 13 patients with gastric non-Hodgkin's lymphoma, who underwent surgery between Jan 1st, 1984, and Sept 1st, 1987. Common symptoms included abdominal pain, weight loss and decline in health and strength. Endoscopy or barium studies had established the diagnosis of a gastric neoplasma in 12 cases. A total gastrectomy (n = 4) or a distal resection (B I n = 3, B II n = 5) was performed, depending on the size of the tumor and its location. Potentially curative resection was followed by radiotherapy in patients with high-grade lymphoma (stage I E). Patients with involvement of regional lymph nodes and advanced gastric lymphoma (stage II E1-IV E) underwent postoperative chemotherapy. So far follow-up (mean 25.3 months) revealed one case of relapse. These results confirm the value of surgical treatment in diagnosis, staging and treatment of primary gastric lymphoma. Survival in patients with advanced lymphoma and high-grade malignancy can be improved significantly by radical tumor resection, followed by multiagent chemotherapy and radiation.

[Diffuse eosinophilic gastroenteropathy].

Eosinophilic gastroenterocolitis is a very rare disease of the gastrointestinal tract. As a result, frequently the diagnosis is missed and/or symptoms get misinterpreted. Histological examination and blood analysis however support the finding of the correct diagnosis in most cases. We report here the case of a 47 year old female patient with diffuse gastroenterocolitis and we will comment the diagnostic problems.

[The solid-cystic pancreas tumor].

Solid-cystic pancreas neoplasia is a rare condition mostly observed in young adults and women. We report three cases of this rare tumor. In all three instances the patients were young, slender women. The tumors were removed by total resection of the pancreas. In two cases these tumors were very large. In two cases we also observed criteria which could indicate that these tumors were malignant: the tumors had infiltrated the adjacent spleen and adjoining lymphnode or displayed a destroyed capsula. Until now, such infiltrative or malignant qualities have not been reported. That such criteria can be conclusively evaluated as an indication of malignancy, remains, however, unclear.

[Camurati-Engelmann disease (progressive diaphyseal dysplasia). Differential diagnostic problems].

The Camurati-Engelmann disease is characterized by sclerotical hyperostosis, which can appear mainly bilaterally symmetrical at the diaphyses of the long bones, but also at all other bones of the skeleton. The Camurati-Engelmann disease is a rare one, up to now hardly more than 120 cases have been published. The rarity explains the fact that the disease is often misdiagnosed and mistaken for other bone diseases. This is a case report of a Camurati-Engelmann disease which was detected by radiological diagnosis. The problem of differential-diagnosis is described.
