Topical pharyngeal anesthesia improves tolerance of upper gastrointestinal endoscopy: a randomized double-blind study.

BACKGROUND AND STUDY AIMS: The usefulness of topical pharyngeal anesthesia is not well established. The aim of the present study was to determine its benefits in relation to patient tolerance and facilitation of the procedure in unsedated patients undergoing upper gastrointestinal endoscopy. PATIENTS AND METHODS: A randomized double-blind study comparing Topicaina spray - a mixture of benzocaine butyl aminobenzoate (butoforme), amethocaine, and butacaine - and a placebo was carried out on 256 outpatients referred for diagnostic endoscopy. No additional premedication was used. After the examination, both the tolerance to and difficulty of the intubation and examination were evaluated by patients and endoscopists respectively, using visual analogue scales and a questionnaire. RESULTS: Three patients (1.2%) did not tolerate the endoscopy. One patient was excluded for unexpected therapeutic endoscopy. One hundred twenty-five patients received the active spray and 127 received the placebo. The two groups were similar with respect to patient characteristics. Both intubation and examination, assessed with visual analogue scales, were better tolerated (both p = 0.0001) and more easily performed (p = 0.02 and p = 0.0001 respectively) in the active treatment group. Patients receiving the active spray had a better tolerance for the procedure, according to questionnaire replies. CONCLUSIONS: Topical pharyngeal anesthesia in unsedated patients undergoing diagnostic upper gastrointestinal endoscopy improves tolerance and makes examination easier.

Endoscopic sclerotherapy in upper gastrointestinal bleeding due to the Mallory-Weiss syndrome.

OBJECTIVES: Therapeutic endoscopic techniques have changed the need for emergency surgery in gastrointestinal bleeding episodes. However, there is only little information about endoscopic therapies in severe gastrointestinal bleeding due to the Mallory-Weiss syndrome. The aim of this clinical study was to assess the usefulness of early endoscopic examination and sclerotherapy for severe or recurrent bleeding due to the Mallory-Weiss syndrome. METHODS: We studied all 50 cases of gastrointestinal bleeding secondary to the Mallory-Weiss syndrome seen in 2175 consecutive emergency endoscopic examinations performed in a University Hospital over a 3-year period. Endoscopic sclerotherapy (1/10000 adrenaline + 1% polidocanol) was performed in all patients with active bleeding or visible vessel at endoscopic examination. The remaining patients were medically treated. RESULTS: Active bleeding or a visible vessel were found in 13 patients; definitive hemostasis was obtained in all cases with sclerotherapy. The remaining 37 patients were successfully treated by conservative therapy. On admission, the severity of the hemorrhagic episodes was significantly higher in patients treated with sclerotherapy than in those who did not require this procedure. An esophageal perforation, successfully managed by conservative means, was the only complication recorded in the subset of patients undergoing sclerotherapy. CONCLUSIONS: Severe bleeding due to Mallory-Weiss syndrome can be successfully treated by sclerotherapy. Early endoscopic examination is an accurate procedure in identifying patients who do not require sclerotherapy.

Intraoperative colonoscopy in patients with colorectal cancer.

Sixty-seven patients underwent intraoperative colonoscopy during elective surgery for colorectal cancer. Complete examination of the colon was achieved in 65 patients (97 per cent), albeit with insertion through a colotomy in three (4 per cent). A synchronous carcinoma was found in six patients (9 per cent), which necessitated a change of planned surgical procedure. Synchronous polyps were detected and removed in 24 patients (36 per cent); two had polyps with carcinoma in situ. The mean age of patients with synchronous carcinoma was significantly higher than that of those without (74.1 versus 61.2 years, P = 0.02). Intraoperative colonoscopy took a mean of 15 min surgical time and only two minor complications (serosal lacerations) were encountered. In patients with colorectal cancer, intraoperative colonoscopy allows complete assessment of the colon and identifies synchronous lesions.

Dietary factors and stomach cancer in Spain: a multi-centre case-control study.

A multi-centre case-control study of diet and gastric cancer was carried out in 4 regions of Spain (Aragon, Castile, Catalonia and Galicia). We selected 354 cases of pathologically confirmed gastric adenocarcinoma from 15 hospitals, representative of nearly all those in the study areas. A control for each case, matched by age, sex and area of residence, was selected from the same hospital as the case. Habitual diet was investigated by the dietary history method, and past diet by means of a frequency questionnaire. The results regarding consumption of food items are presented here. With respect to habitual diet, an increase in risk was associated with consumption of preserved fish, cold cuts and oleaginous fruits. A high intake of cooked green vegetables, fresh noncitrus fruit and dried fruit showed an inverse association with the risk of gastric cancer. Simultaneous intake of 2 groups of food which increase or decrease the risk of cancer strengthens the respective individual effect. The intake of protective food items seems to neutralize the effects of food items which increase risk. With reference to past diet, a possible protective effect was observed for daily consumption of fresh fruit and green vegetables.

[A descriptive epidemiological study of ulcerative colitis in a community hospital (1985-1989)].

BACKGROUND: The incidence of ulcerative colitis (UC) shows a marked geographical variation. It is high in Anglo-Saxon and Scandinavian countries, while in Mediterranean countries the available data on its epidemiological features are few. Spain is not an exception. METHODS: The new cases of UC diagnosed during the period 1985-1989 in the Hospital de Sabadell (a reference center of an area with a markedly industrial population of 343924) were retrospectively evaluated. The definitive diagnosis of UC required a negative fecal microbiological study and findings in colonoscopy and biopsy consistent with UC. RESULTS: During the study period 68 new cases of UC were diagnosed, representing a mean yearly incidence of 3.95/10(5) population, and 5.26/10(5) considering only the adult population (age greater than 14 years). No significant differences were found (p greater than 0.05) in the sex and age distributions, although the male/female ratio was 1.06. In 84% of cases UC was limited to the rectum and/or distal colon, with a low frequency of pancolonic forms (5%). In 70% of patients UC was classified as a low severity disease. CONCLUSIONS: Although the estimation of incidence only from hospital cases underestimates the true incidence, and also considering the limitation of comparing results of studies from several time periods, the incidence of UC in our area is the highest one reported to the present time in Spain and Southern Europe. Nevertheless, it is lower than that in most Northern European countries.

Site and size of bleeding peptic ulcer. Is there any relation to the efficacy of hemostatic sclerotherapy?

In 78 patients with high-risk bleeding peptic ulcers (either with active bleeding or non-bleeding visible vessel) endoscopic hemostasis by injection of adrenaline and polidocanol was attempted. Sclerotherapy was performed in 70 (90%) patients. Initial hemostasis was achieved in 35 (94.5%) patients with active bleeding, and permanent hemostasis in 61 (87%). Efficacy of injection therapy was significantly lower in ulcers larger than 2 cm (p = 0.001), and in those located on the posteroinferior duodenal wall (p = 0.03). It was not possible to perform endoscopic injection in 8 (10%) patients due to difficulty of access, lesions located mainly high on the lesser gastric curvature and on the posteroinferior duodenal wall. From these results we conclude that endoscopic injection is a very useful technique for the initial treatment of high-risk bleeding peptic ulcer, although the size and anatomical location of the lesions may be a limitation of its use.

Occupation and gastric cancer in Spain.

The association between occupational exposure and stomach cancer was investigated in a multicenter case-referent study conducted in Spain on 354 histologically confirmed cases and 354 hospital referents, matched by age, gender, and residence. An increased risk of gastric cancer was found for coal mining workers [odds ratio (OR) 11.8], but the number of workers was small, and therefore the 95% confidence interval (95% CI) was wide (95% CI 1.36-103). An increased risk was observed for wood and furniture workers (OR 1.76), construction workers (OR 1.68), and glass and ceramic workers (OR 2.18), but none of these risks were statistically significant. According to an occupation-exposure linkage system an increased risk was found for occupations associated with exposure to silica and mineral dust (OR 1.80, 95% CI 0.90-3.59). All of the OR estimates were adjusted for the confounding factors socioprofessional status and dietary habits. The possibility of a causal association between stomach cancer and coal and mineral dust is supported by the results.
