Sedation for gastroscopy: a comparison between midazolam and midazolam with nalbuphine.

Forty patients received either midazolam or midazolam with nalbuphine in a double-blind randomised study of sedation for upper gastrointestinal endoscopy. There were less retching, gagging and salivation in the combination group compared to midazolam alone. They were also more cooperative. These resulted in greater ease of insertion of the gastroscope. There was no significant difference in the degree of amnesia in both groups. A significant decrease in oxygen saturation was noted in both groups during the procedure. Monitoring with a pulse oximeter is recommended when sedation is administered during gastroscopy.

[Nosocomial transmission of Helicobacter pylori through fiberoptic gastroscopy].

The relationship of nosocomial transmission of Helicobacter pylori (Hp) by fiberoptic gastroscopy was investigated. Hp was cultured from the materials obtained from the suction/biopsy channel (4/12 times) and biopsy forceps (3/10 times). The positive rate of Hp was increased with times undertaking endoscopy in the past in elder patients with chronic gastritis. The rate from Hp negative transforming into positive also increased with the times of receiving endoscopic follow-up in the past in patients with Hp negative chronic gastritis. The average age of Hp positive patients were older in those patients under follow-up studies than that in randomly age-matched normal or chronic gastritis controls. The results suggested that the contamination of gastroscopic equipment played a potential role as vehicle causing nosocomial infection of Hp. The risks of Hp transmission correlated with times of undertaking endoscopy, especially in the elderly.

[Significant value and therapeutic implications of routine gastroscopy before cholecystectomy].

Endoscopy of the upper digestive tract was performed in 338 consecutive patients undergoing cholecystectomy between January 1991 and December 1992. Pathological findings were seen in 160 (47.3%), 6.8% of the patients had peptic ulcers, 1.8% gastric erosions, 25.7% gastritis, 3.2% polyps, 4.7% hiatal hernias, 3.0% oesophagitis and 0.6% gastric cancer. In most patients the gastroscopic results did not correlate with the clinical symptoms. The therapy concept had to be changed in 8.3% of the patients due to gastroscopic findings, 23 patients with ulcers, 2 with erosions and 1 with oesophagitis had to be treated medically and so the cholecystectomy was postponed. Two patients with gastric cancer underwent gastrectomy. These results underline the importance of a routine gastroscopy before elective cholecystectomy.

[A new method of administering analgesic sedation before gastroscopy--a comparative study of 100 patients].

The authors administered to two groups (56 and 44) patients before gastroscopy analgosedation-5 mg diazepam and local anaesthesia of the throat. To the first group diazepam was administered by the i.v., to the second group by the sublingual route. The objective was to find out whether analgosedation is desirable from the patients aspect and whether the sublingual form of premedication is accepted by the patients. The authors found that 90% of the patients wish to have analgosedation and anaesthesia before the procedure. The sublingual form of administration was accepted by 89% of the patients.

[Myocardial infarct after gastroscopy. Case report and pathogenetic considerations].

Three cases are reported of myocardial infarction and severe myocardial ischemia following gastroscopy in patients with coronary heart disease. These cases demonstrate the high risk of endoscopy in such patients. It is assumed that the main pathogenetic factors are catecholamine-mediated tachycardia and the close vicinity of the lower esophagus to the right coronary artery, with its tendency to coronary spasmus.

Gastrointestinal blood loss. Effect of aspirin, fenoprofen, and acetaminophen in rheumatoid arthritis as determined by sequential gastroscopy and radioactive fecal markers.

The feasibility of determining the exact site and amount of drug-induced gastric bleeding was tested. Fourteen patients with rheumatoid arthritis received equivalent therapeutic doses of the antinflammatory drugs aspirin, 4 gm/day, and fenoprofen calcium, 2.4 gm/day, in randomized order for seven days. Acetaminophen was given for 14 days just prior to each of these periods. By fiberoptic gastroscopy, antral ulceration and acute mucosal lesions were found in seven patients following aspirin ingestion, in one taking fenoprofen, and in none taking acetaminophen. Fecal blood loss in four-day stool collections, quantitated by autologous chromium 51-labeled erythrocytes shed into the stool averaged 5.0 ml/day while taking aspirin, 2.2 ml/day while taking fenoprofen calcium, and 0.8 ml/day while taking acetaminophen. The mean blood loss was greater for those in whom gastric lesions developed while taking aspirin than for those in whom lesions did not develop. The short-term risk of erosive gastritis was greater for aspirin than fenoprofen.

No effect of oxygen therapy on myocardial ischaemia during gastroscopy.

BACKGROUND: Myocardial ischaemia (defined as an ST-segment depression on ECG) may occur during upper gastrointestinal endoscopy, but the mechanism is still unknown. The aim of our study was to evaluate the effect of oxygen therapy and tachycardia on the occurrence of ST-segment depression during routine diagnostic esophagogastroduodenoscopy. METHODS: Eighty-nine consecutive patients were randomized to receive either oxygen (21/min by nasal prongs) or nothing during endoscopy, in which arterial oxygen saturation was measured by continuous pulse oximetry, and ECG was measured continuously with a Holter tape recorder. RESULTS: A total of 28 patients (12 receiving oxygen) developed ST-segment depression ( > 0.1 mV) during endoscopy. In 22 patients (12 receiving oxygen) ST depression was related to tachycardia, and in 5 of these (none receiving oxygen) simultaneous episodic hypoxaemia was present during the event. Thus, in every case of ST depression related to episodic hypoxaemia there was simultaneous tachycardia. In six patients developing ST depression during endoscopy we did not find preendoscopy levels, and 63 patients (29 receiving oxygen) developed tachycardia during the procedure (rate > 100 min-1_. CONCLUSIONS: Oxygen therapy had no significant effect on the occurrence of ST-segment depression during upper gastrointestinal endoscopy. The results suggest that tachycardia is more important than hypoxaemia in the pathogenesis of ST depression during gastroscopy.

[The value of aimed biopsy in gastroscopy].

The introduction of the fiberscops with the possibility of the aimed biopsy has considerably improved the diagnostic evidence of gastroscopy, though there exists a whole series of technical problems in the histological ascertainment. Though all regions of the stomach are accessible to the biopsy forceps, the histological findings cannot always be ascertained clearly histologically. Of 105 carcinomata of the stomach and the oesophagus only 84 were verified clearly histologically. Of 101 ulcers appearing benign five proved to be malignant in histological respect. In 14 scars in two cases a carcinoma could be proved. Altogether from 27 polyps appearing benign bioptic material was taken, which in all cases confirmed the primary diagnosis, nevertheless at the operation one polyp proved to be malignant. In 105 cases endoscopically the diagnosis of a carcinoma was made, but in seven cases it was a benign ulcer clearly confirmed by the operation. It is reported on some own experiences concerning the improvement of the result of the aimed biopsy.

Percutaneous endoscopic gastroscopy tube migration: a rare cause of a common surgical problem.

Percutaneous endoscopic gastroscopy (PEG) is now the preferred method for long-term enteral nutrition for patients with inadequate oral intake. It is usually replaced by a Foley catheter when it becomes non-functional because of blockage or wear and tear. PEG tube migration is an unusual complication which may not be noticed by the patient or the medical staff and may present as delayed small bowel obstruction. We report on a patient who developed such a complication and the missing PEG tube was replaced by a Foley catheter when it was thought the original tube had fallen out. The use of catheters with an external stop device is recommended to prevent this rare complication.

Acustimulation of the Neiguan point during gastroscopy: its effects on nausea and retching.

BACKGROUND/AIMS: Gastroscopic procedure causes nausea and retching in many patients. Recently, alternative methods have been employed in an effort to reduce these symptoms. The Neiguan point (P6) is an acupuncture point that has been used for approximately 3,000 years to overcome gastric symptoms including nausea and retching. The aim of this study was to investigate the effects of the stimulation of the P6 acupoint on swallowing, nausea and retching during the gastroscopic procedure. METHODS: Three hundred and twenty-seven patients who visited the gastroenterology unit for dyspeptic complaints were included in the study. A portable transcutaneous electrical nerve stimulation device (Reliefband; Maven Lab, Yuba City, CA) was used for acustimulation. The device was attached 15 minutes before the endoscopic procedure and no sedation was applied. The device was turned on in 78 patients (Group 1). The device was attached but not turned on in another 79 patients (Group 2). In Group 3, the device was attached to the Sham point (n: 79). In Group 4 the procedure was performed with no attachments (n: 77). Fourteen patients dropped out of the study because esophagogastroduodenoscopy could not be completed due to patient intolerance or to obstruction in the upper gastrointestinal tract. After the procedure, each patient's opinion about the severity of nausea and retching was measured on a visual analogue scale. Distress in swallowing and the impression of the endoscopist during the procedure were scored from 1 to 4. Patients were queried regarding their willingness to undergo re-endoscopy. RESULTS: Groups were compared regarding their distress in swallowing the endoscope, nausea and retching, the impression of the endoscopist during the procedure and their acceptance of re-endoscopy. Groups 1, 2, 3 and 4 were compared using the chi-square test, and no significant difference was observed between the groups (p>0.05). CONCLUSIONS: Acustimulation of the Neiguan (P6) acupoint does not relieve patients of the nausea observed during gastroscopy, and its application does not facilitate the procedure.

[Disposable protection for flexible gastroenterologic endoscopy: prospective comparative evaluation of a new gastroscopy system (Endosheath) compared to the standard fiberglass gastroscope].

The reprocessing of flexible gastrointestinal endoscopes is time-consuming and expensive. Endoscopically transmitted infections due to insufficient disinfection are already of clinical importance. A new developed prototype of a flexible, fiberoptic gastroscope was tested in a prospective open randomized trial to evaluate the function. reprocessing and hygienical safety of this disposable, sheathed endoscopic system and was compared with a standard gastroscope. This new endoscopical system utilizes a disposable sheath to cover and protect all working surfaces of the endoscope from contamination. A prospective, randomized trial was performed in our unit to compare the disposable gastroscope (G-F100) with a standard-gastroscope of the newest Generation (GIF-Q 30). Visual analog rating scales were used to record evaluations of endoscope performance and reprocessing by endoscopists and reprocessing personnel. We recorded the time of reprocessing, the time to perform the procedures, depth of insertion, total instrument downtime and any problems which occurred during the procedure. Microbiological swabs were taken from each endoscope. 40 procedures (20 standard, 20 sheathed) were performed. The sheathed gastroscope 8.9 min versus 7.1 min. The overall instrument downtime was significantly shortened by the endosheath (9.8 min versus 47.5 min with the standard gastroscope). The disposable gastroscope-system permits an increase of procedure-frequency up to a factor of 2.9. The standard gastroscope was preferred by the endoscopists and the reprocessing personnel. No microbiological contaminations of the sheathed or the standard gastroscopes could be demonstrated, and no leak of the sheaths was recorded after gastroscopy. The disposable gastroscope has important advantages of decreased instrument turn-around time and potentially increased staff and patient safety.
