[The significance of laboratory chemical parameters for the diagnosis of mesenteric infarction (author's transl)].

A laparotomy was performed on 23 dogs with and without ligation of the mesenteric artery. Twenty-eight laboratory parameters of blood samples taken immediately and then every two hours after the operations were checked for systematic trends. The analysis of variance showed some differences between both groups. It was impossible to use the individual results of this investigation for a general diagnostic approach. Difficult and long-lasting biochemical investigations are of dubious value since time loss is one of the most important problems in mesenteric occlusion. Indications for invasive diagnostic procedures and for laparotomy should not be postponed; they should depend on the different aspects of clinical symptoms, as it is practised now.

[Morphology and physiopathology of Billroth I gastroduodenostomy].

97 patients subjected from 1 to 7 years previously to partial gastric resection by gastroduodenostomy (Billroth I) have been studied endoscopically and radiologically. Acid secretion after pentagastrin injection has also been determined. The most frequent mucous alterations identified by endoscopy were erosions in the stomach residue with inflammatory granulation in the anastomosis region. Recurrent ulcers were observed in 3% of cases. Acid secretion was reduced in 87% by comparison with the preoperative picture. The quantity of residual recretion depended on the greater curvature of the residual stomach. Radiological studies highlighted functional modifications indicative of organized motility in the residual stomach and pseudopyloric function at anastomosis level making coordinated draining possible.

[Morphology and pathophysiology of Billroth I gastro-duodenostomy (author's transl)].

Endoscopic and radiological studies were undertaken in 97 patients who had had a partial gastric resection with gastro-duodenostomy (Billroth I) one to seven years previously. Acid secretion was also analyzed after injection of pentagastrin. The most frequent mucosal changes seen at endoscopy were erosion in the residual stomach, with inflammatory granulation in the region of the anastomosis. Recurrent ulcers were seen in 3%. Acid secretion was reduced by 87% from its pre-operative level. The amount of residual secretion depended on the length of the greater curvature in the residual stomach. Radiological studies revealed functional changes indicating that there is a motility pattern in the residual stomach and a pseudopyloric function at the anastomosis which makes co-ordinated emptying possible.

[Endoscopy of postoperative hemorrhage in the upper gastrointestinal tract].

In hemorrhages from the upper gastrointestinal tract, emergency endoscopy is becoming more and more significant. Hemorrhages during the early postoperative stage, particularly in abdominal surgery, require particular attention due to the generally difficult postoperative situation. In most instances, intragastral hemorrhages are due to erosions and anastomotic bleeding. A detailed knowledge of the surgery performed may contribute to a quick and successful examination. Among the most important premises for a high rate of correct diagnoses are the experience of the examining physician as well as an early or immediate identification of the indications. In addition to the diagnostic significance, under favorable circumstances endoscopy makes possible definitive or temporary staunching of the bleeding by means of diathermy, laser beam or sclerotization.

[Pancreatic pain: a clinical-experimental study].

In 26 patients endoscopic-radiologic pancreography routinely performed caused severe pain with certain origin from pancreatic glan. Pain could be stopped immediately and with constant effect by lingual application of nitroglycerine. According to these informations we suppose that pancreatic pain is started by vascular reactions and ischemia. The good effect of nitroglycerine is worth a control in patients with common acute pancreatitis.

[Duodenal reflux and gastritis after Billroth I gastric resection (author's transl)].

Endoscopic and biopsy studies were undertaken in 92 patients who had undergone partial gastric resection (end-to-end gastroduodenostomy, Billroth I) one to seven years previously. In addition, the amound of duodeno-gastric reflux was evaluated by measuring bromsulphalein excretion in gastric juice. Atrophic gastritis occurred in 36%, while superficial gastritis was noted in 49% of patients. The degree and severity of the inflammatory changes was most marked near the anastomosis. The severity of the duodenal gastric reflux was decisive in the development of the atrophic mucosal changes. There was no demonstrable relationship between the degree of mucosal changes and the interval since the operation.

[Endoscopic transpapillary cholangiography (author's transl)].

Endoscopic transpapillary Cholangiography is able to give valuable informations for indication and operative procedure in biliary diseases especially in obstructive jaundice. Indication for "blind" explorative laparotomy seems to become more rare as well as necessity for clearing situations of biliary tract by surgical preparation or X-ray-examinations as usually performed. If one is well trained in technical procedures and in interpretation of radiologic findings, very helpful diagnostic hints can be presented. In opposition to retrograde pancreaticography, endoscopic examination of the biliary tract can be propagated with more enthusism.

[Radiological and clinical aspects of resection of the cardia].

Following resection of the cardia, problems may arise during two phases; in these, clinical and radiological examination may be required. Immediately after the operation one is concerned particularly with checking the incision or the extent and localisation of suture abnormalities. In the late post-operative period the problems are different. In addition to a description of the anatomy at the proximal and distal ends of the stomach, it is necessary to estimate functional conditions, such as passage through the anastomosis and the pylorus, the reservoir function of the gastric remnant and gastro-oesophageal reflux. An important task is to demonstrate tumour recurrence. For this purpose endoscopic, biopsy and cytological examinations are required.

[Postoperative pancreatitis].

Incidence and extent of increased alpha-amylase concentration were examined in serum and urine following routine surgical intervention in the epigastrium. Only patients with non-specific clinical symptoms (n=49) and a control group who had undergone surgery for inguinal hernia (n=10) were included in the study. Patients previously subjected to gastric surgery (selective gastric vagotomy = 10, gastric resection according to Billroth I = 10) were significantly more often found to have results within a range usually considered pathological. Patients who had undergone surgery of the bile duct were markedly less affected. The diagnosis, based on the benefit of the hindsight, of a postoperative pancreatitis in cases where specific complaints and increased maylase concentration coincide does therefore not appear justified--particularly following gastric surgery. This becomes significant if a choice between various conservative treatments or relaparotomy is being considered.
