[Radical D2,D3 lymph node excision of stomach carcinoma in situs inversus totalis and malrotation of the colon].

The combination of Situs inversus totalis (SIT) with incomplete rotation of the colon is an extremely rare anomaly and especially of interest when presented with advanced gastric cancer. The routine en-bloc resection of gastric cancer with D2,D3 lymphadenectomy according to the recommendations of the Japanese Research Society for Gastric Cancer [5] can, as in this case, present tactical operative problems, due to the mirror-image anatomy and potential vessel anomalies, which might complicate the operative procedure. The preoperative diagnosis of SIT is not only essential to allow an adequate operative approach but furthermore to prevent vessel injury.

Bovine dowels for anterior cervical fusion: experience in 66 patients with a note on postoperative CT and MRI appearance.

Anterior cervical discectomy and vertebral interbody fusion is a widely used technique in the treatment of radicular or cord compression. Instead of using autologous bone removed from the iliac crest, a heterologous bovine dowel was used for fusion. Sixty-six patients presenting with radicular pain or myelopathy were entered into the study retrospectively. Medial herniated, soft or calcified disc, osteophytes with and without herniated disc material, and bony stenosis at one or two levels were shown by CT or MRI studies. Postoperatively, 88% of the patients noted relief of pain and motor improvement. Most of the patients' sensory deficits and myelopathy improved within 6-12 months. No complications occurred and only one re-operation had to be performed at the same level. In the follow-up period between 1-4 years, no cases of instability after surgery were reported. Operating time and postoperative pain were reduced because bone harvest from the iliac crest was not necessary. In postoperatively performed CT and MRI, the bovine dowel was surrounded by a "halo"-like structure and the specific structure of the bovine implant was still present. No real bony fusion occurred, but clinical stability was equivalent to autologous bone fusion reported in the literature. However, there was no MRI evidence of "living bone tissue" within the bovine dowel. This finding is in contrast to the current belief that the bovine implant is replaced or infiltrated by bony growth.

[Intracranial hemorrhages in mature and premature infants. Computer tomography and clinical follow-up studies].

The findings of CT-follow-up-studies on a group of 94 infants, who had suffered intracranial hemorrhage, were correlated with the clinical and neurological outcome. Purpose of the retrospective study was to work out prognostic criteria dependent on the typ and location of the hemorrhage. Among the infants with intraventricular hemorrhage, there was a direct relationship between the severity of the hemorrhage and major handicaps on the one hand and the mortality rate on the other hand. Neurologic sequelae were noted in 16.5% of the infants with tentorial hemorrhages, in 56% of the infants with intracerebral hemorrhages and 37.5% of the infants with subarachnoid hemorrhages. Our results indicate, that the outcome of infants with intracranial hemorrhages is not dependent on the typ and severity of the bleeding only, but is also influenced by additional factors, like perinatal asphyxia.

[Spontaneous rupture of an infected kidney cyst].

Spontaneous or traumatic rupture of renal cysts is a rare occurrence. The contents of the cyst can perforate into the renal calyx system or into the perirenal space. Perforation into the peritoneal cavity has also been described (1, 2, 4, 5).

Does acute endoscopic evacuation improve the outcome of patients with spontaneous intracerebral hemorrhage?

A new endoscopic technique is presented, which allows burr hole evacuation of intracerebral hematomas under video control. Clot removal is achieved using a suction-irrigation system built in the 6-mm-diameter endoscope; in addition, an ultrasonic morcellement device has been developed for transendoscopic application. Small bleeding vessels in the hematoma cavity can be coagulated using a 1.5 mm Neodym YAG Laser microprobe introduced through the endoscope under visual control. A randomized prospective study has been started to raise again the question of indications for the surgical treatment of intracerebral hemorrhages, comparing medical treatment with the new surgical technique.

[Sonographic visualization of the left ovarian vein. A contribution to the diagnosis of compression syndrome of the left renal vein].

Amongst 737 sonographic and CT examinations of women aged 18 to 60 years of age, seven cases of ectasia of the left ovarian vein were found (0.95%). The aetiology and significance of this finding in the context of the "compression syndrome of the left renal vein" are discussed. The value to sonography in elucidating this condition is stressed.

[Transabdominal sonography of the lumbar intervertebral disks and intraspinal structures].

This paper reports a prospective study on 64 patients in whom sonography was used to diagnose pathological changes in lumbar discs and intraspinal space occupying lesions; the results were compared with myelography and computer assisted tomography (CAT). The sonographic device used was a mechanical sector scanner with a medium focused transducer with a frequency of 3.5 MHz. The normal and pathological anatomy as shown by ultrasound was correlated to the known anatomy of CAT-scanning; the nerve roots, the dural sac and the intervertebral discs were recognizable in sonography and in CAT. The extent of an intraspinal lesion beyond the upper and lower limiting planes of the intervertebral discs were not demonstrable by ultrasound. The sonographic study was at least partially successful in 55 of 64 patients (86%). It failed in 14% (9 cases) because of obesity or because of diminution of the intervertebral space. The study revealed a specificity and sensitivity of transabdominal spinal sonography of 0.86 respectively 0.84.

[Sonographic demonstration of an ectopic ureter orifice].

In a case report an ectopic ureter evaluated by means of ultrasound and proved by surgery is discussed with respect to its embryologic development, incidence and clinical aspects. Sonography is shown to be of diagnostic value in localizing the orifice of an ectopic ureter.

[Pancreas cancer: staging with dynamic computerized tomography].

Carcinoma of the pancreas continues to present a most unfavorable prognosis. 90% of the tumours cannot be operated on and the survival time of these patients is 2-6 months. In a prospective study based on 23 patients it was investigated whether comprehensive staging of the carcinoma of the pancreas can be performed via computed tomography so that operable carcinomas alone must be presented for laparotomy. Results of CT were compared with those of angiography and laparotomy. Differentiation between stage 1 (tumour restricted to organ) and stage 2 (limited lymph node metastasising) is limited if effected via CT. However, it was possible to differentiate between the non-operable stages 3 and 4 with a sensitivity of 88% and a specificity of 78%. CT showed particularly high sensitivity in patients with vascular involvement.

[Involvement of diaphragmatic lymph nodes in Hodgkin's disease].

The authors report on a case of Hodgkin's disease with enlargement of diaphragmal lymph nodes. Detailed attention is paid to the anatomy, radiological diagnosis and differential diagnosis of these mediastinal lymph nodes. The clinical importance of this group of lymph nodes in Hodgkin's disease and in non-Hodgkin lymphomas is discussed.

[Liver metastases: sonography or scintigraphy? A comparative prospective study].

In 278 patients with known malignancy a sonogram, scintigram and laboratory examination were done on the same day. The comparison of the examinations revealed nearly the same accuracy for both imaging modalities with 90% for sonography and 89% for scintigraphy. Sonography showed the more uniform results, because scintigraphy had a high percentage of false positive results. The value of both methods as the utility of an additional laboratory examination are discussed.

[Free programmable image functions (windows) for computer tomography].

Software windows are a flexible and general method for defining arbitrary functions for the mapping of Hounsfield-numbers of CT-scans on to the grey levels of the display image. The method which is illustrated with the aid of a few examples has been implemented on an EMI viewing console.
