[The x-ray characteristics of the function of the upper digestive tract in nonspecific ulcerative colitis].

A roentgenological examination was carried out of the upper regions of the digestive canal in 52 patients with unspecific ulcerative colitis with a different extension of the pathological process in the colon. The obtained results were verified by means of fibrogastroduodenoscopy. Most of the examined patients revealed pathological changes in the stomach and duodenum that significantly deteriorate the course of the main disease. There was a direct dependence between the frequency of inflammatory lesions of the gastroduodenal zone and severity of the course of unspecific ulcerative colitis.

[The importance of the diagnostic imaging of malignant gastrointestinal tumors for radiotherapy].

The importance of diagnostic imaging in malignant gastrointestinal tumors has moved from the primary diagnosis towards staging and follow-up studies. An accurate staging by diagnostic radiology is the cornerstone in planning radiation therapy. Especially in estimating the T- and N-stage as well as the primary diagnosis in esophagus-, gastric and rectal cancer endoscopy with endoscopic ultrasound is the method of choice. When planning radiation therapy barium studies of the esophagus and contrast enema of the colon are important. Only in the case of gastric lymphoma an upper gastrointestinal series is necessary. In the case of suspected recurrent rectal cancer CT-guided biopsy distinguishes between tumor recurrence and reactive fibrosis.

Status evaluation: endoscopic ultrasonography. American Society for Gastroenterology Endoscopy. Technology Assessment Committee.

Endoscopic ultrasound is a new technology that improves the local staging of esophageal, gastric, and rectal carcinomas. In addition, EUS may provide useful information which will affect management in individual patients with subepithelial masses (e.g., varices, leiomyomas) and pancreatic diseases. Other imaging studies such as transcutaneous ultrasonography and CT are still necessary to detect distant metastatic disease. At present, EUS may be best reserved for use by individuals who have sufficient patient materials to provide broad experience with the technique. Physicians at centers where large numbers of patients with gastrointestinal cancer are evaluated may find this technology most useful. Even in patients with malignancy, however, studies are needed to show that the improved local staging by EUS will translate into changes in patient management and improved outcome.

Predictive value of visible lesions (cheeks, lips, oropharynx) in suspected caustic ingestion: may endoscopy reasonably be omitted in completely negative pediatric patients?

The relationship between absence or presence of grossly visible lesions in the cheeks, lips, and oropharynx (C.L.O. burns) and the incidence, site, and degree of visceral burns was evaluated in all children referred to our hospital for a suspected caustic ingestion during a 10-year period. All children underwent eso-gastro-duodenoscopy within 24 hours. Of the 156 children, 96 (61.6%) showed no visible signs of contact with the caustic substance; however, in 36/96 (37.5%), endoscopy revealed burns in one or more visceral sites. Eight of 36 children (22.2%) sustained potentially dangerous lesions (second to third degree). Sixty of 156 children (38.4%) showed visible lesions; in 30/60 (50%), endoscopy revealed other burns in one or more visceral sites. Fourteen of 30 patients (46.6%) sustained potentially dangerous lesions (second to third degree). A total of 50 esophageal burns have been recorded: first degree (E1), 32; second degree (E2), 12; third degree (E3), 6. Two of 12 patients with E2 lesions and 6/6 with E3 lesions developed esophageal stenosis. One patient in this latter group died because of complications related to a tracheostomy. A total of 31 gastric burns have been recorded: G1 (22), G2 (6), G3 (3). One gastric perforation was observed in the G3 group, whereas the remaining two lesions healed with residual asymptomatic scarring. Minimal scarring was observed in two of six patients with G2 burns. A total of eight lesions have been recorded in the larynx [L1 (3), L3 (1)] and in the duodenum [D1 (2), D2 (2)].(ABSTRACT TRUNCATED AT 250 WORDS)

[Therapeutic endoscopy in diseases of the digestive system].

A study of 374 patients with ulcer disease, chronic gastroduodenitis and esophagitis allowed to distinguish three clinico-endoscopic syndromes (erosive-ulcerative, irritated pylorus, regurgitating syndromes). Therapeutic endoscopic manipulations were carried out: transesophageal block of the vagal nerve, pricking of the ulcer with trimecaine, solkoseryl, oxyferriscorbone, trental and laser treatment. The results were favourable.

[Echo-endoscopy of the digestive system].

Endoscopic ultrasonography of the gastrointestinal tract allows a precise ultrasound study of the accessible gastrointestinal walls (oesophagus, stomach, duodenum, rectum) and, through these walls, of the adjacent organs (lymph nodes, posterior mediastinum, pancreas, extrahepatic biliary ducts and perirectal region). This method is better than computerized tomography to evaluate the local and regional extension of oesophageal and cardial carcinomas producing little or no stenosis and of gastric and rectum carcinomas and lymphomas. It is the examination of choice to detect a perianastomotic recurrence of these cancers and to evaluate submucosal tumors of the gastrointestinal tract. This method, with no morbidity, is better than computerized tomography or ultrasonography in the aetiological diagnosis of obstacles in the biliary tract and in the diagnosis and pretherapeutic assessment of pancreatic cancer or endocrine tumors.

[The surgical and endoscopic therapeutic procedures in acute hemorrhages of the upper digestive tract].

A total of 2995 patients with esophagogastroduodenal bleeding have been treated the Department of Emergency Surgery for the period 1984-1988. A significant group were patients in advanced and senile age (beyond 65--42.4 per cent). The therapeutic and surgical approach to gastroduodenal bleeding was based on the solution of the following diagnostic-tactic problems: cause, source, localization and intensity of the bleeding, temporary or definitive hemostasis patterns, severity of blood loss. Essential is also the underlying disease, patient age and accompanying diseases. Express emergency endoscopy allows early and explicit visualization of the pathologic area and enables to gain knowledge on the nature and intensity of the bleeding or the character of spontaneous hemostasis. In this respect, express endoscopy is a guiding principle in managing upper digestive tract bleeding at the Department of Emergency Surgery. Of all hospitalized patients in this study were operated 203. Operations were performed after obligatory attempt for endoscopic hemostasis. The operative case fatality rate for the study period was, as follows: in gastric and duodenal ulcer 21.6 per cent, in gastric cancer 42.0 per cent, in hemorrhagic gastritis 33.3 per cent and in Mallory-Weiss syndrome 9.1 per cent.

[Main indications for upper digestive endoscopy].

Upper gastrointestinal endoscopy (UGI) is now widely accepted as the first-line examination of the digestive tract. UGI provides the diagnosis of most oesophageal and gastroduodenal diseases such as ulcer, cancer or oesophagitis. It is also valuable in the diagnosis of chronic diarrhoea, immunodeficiencies (immunoglobulin deficiency) and in AIDS patients. Improvements in disinfection and anesthesia make UGI a safe and well-tolerated procedure. Finally, it is, of course, the gold standard for the diagnosis of upper gastrointestinal haemorrhages and in many cases requiring endoscopic therapy.

Indications of endoscopic ultrasonography of the digestive tract.

Endoscopic ultrasonography of the digestive tract provides for a precise ultrasonic study of the accessible gastrointestinal walls (esophagus, stomach, duodenum, rectum) and through the walls, of the adjacent organs (lymph node clusters, posterior mediastinum, pancreas, extrahepatic biliary ducts and perirectal environment). This method is more efficient than computerized tomography to evaluate the local and regional extension of esophageal, gastric and rectal carcinomas, producing little or no stenosis. It is the examination of choice to detect a perianastomotic recurrence of these cancers in the aetiological diagnosis of obstacles in the biliary tract and in the diagnosis and the pretherapeutic assessment of pancreatic cancers.

Endoscopic ultrasonography of the upper gastrointestinal tract.

EUS unites two established imaging techniques and extends the range of observation into and beyond the wall of the GI tract. The close proximity of the sonographic probe to the region of interest combined with high ultrasonic frequencies of between 7.5 and 12 MHz yields images of high resolution. EUS is used in the staging of benign and malignant neoplastic disorders of the oesophagus, stomach, pancreas and extrahepatic bile ducts. It helps to establish operability, to plan surgical approach, to follow response to therapy and to search for recurrence. The predictive value in defining the T and N stages of oesophageal carcinoma lies between 80 and 90% and 65 and 85%, respectively. It is clearly superior to CT in tumour stages T1 and T2. In gastric cancer, resectability based on the TNM staging system can be correctly assessed by EUS in 85% of cases and EUS detection and staging of early gastric cancer reaches an accuracy of 90%. The EUS accuracy rate for resectability of pancreatic carcinoma is 83% and tumour infiltration into the portal and splenic vein can be correctly determined by EUS in 94% and 67%, respectively. A reliable EUS differentiation between chronic pancreatitis and pancreatic carcinoma based on the echo pattern and outer margins is not possible. The development of EUS-guided needle biopsy should improve the specificity of EUS in this regard. Experience to data suggests as well that EUS will assume an important place in the staging of bile duct tumours. EUS has expanded our endoscopic and sonographic capabilities and it is to be hoped that further technical improvement, e.g. the construction of forward-viewing endoscopes combined with radial scanning devices, will contribute to a widespread use of this technique by gastroenterologists.

The SADE system: an endoscopic database manager.

The development of the SADE database manager was commenced in 1985 since no commercially available systems were suited for the needs of a large endoscopy unit. Over a period of five years, this database was programmed, revised and enhanced through the joint efforts of gastroenterologists and programmers, the SADE system being implemented for daily use on 1 January 1989. The patient administration and medical record modules are fully implemented and functional, while the statistical module has only recently been finished. The present features of the system are described, and the limitations discussed. Instant report generation and direct access to previous medical data are the most immediate benefits of the system. The initial intention to have structured anamnestic data had to be modified to suit the need for flexibility and ease of free text input by the users.

SADE database for endoscopic procedures: aspects of clinical use.

The time aspects of daily use of a clinical database system in an endoscopy department were studied. The SADE database system for endoscopic procedures was introduced for daily use at Ullevål Hospital on 1 January 1989. The average weekly programme of the endoscopy unit includes 57 gastroduodenoscopies, 23 colonoscopies and 12 ERCP/EPTs. During three consecutive weeks of the study the mean physician input time was 4 min 17 sec per patient (range 57 sec to 15 min), individual variation depending mainly on the extent of the report. Assistants spent a mean time of 4 min 23 sec for each patient. Thus, a total of 8 min 40 sec was spent for every patient seen. Endoscopic units should analyze their routines and needs before introducing an electronic data base manager.
