International scientific production in digestive laparoscopic surgery.

OBJECTIVE: To obtain data on research in laparoscopic digestive surgery over the period of 1991 to 1996. MATERIAL AND METHODS: We used Medline and the Science Citation Index to obtain general data on production. For more specific data (contents, etc.) we used random samples with a confidence level of 99%. RESULTS: There were 4825 publications on laparoscopic digestive surgery and 4.085 on other specialties; of these, articles represented 85% and editorials and letters 15%. University hospitals published 40% of this production. The producing countries were USA (45%), France (8.2%), United Kingdom (7.9%) and Germany (7.5%). The publishing countries were USA (41%), Germany (15.3%), United Kingdom (9.7%) and France (6.7%). The publication with the largest influence was the New England Journal of Medicine with a total Impact Factor of 589; the British Journal of Surgery with a factor of 436, Archives of Surgery with 343, American Journal of Surgery with 336 and Annals of Surgery with 302; the mean relative Impact Factor was 1.886. Method was involved in 756 retrospective studies, 275 prospective studies and 43 random clinical trials; the rest were not series. The majority of contents are on techniques and instruments, indications and general reflections. The most researched anatomical region was the gall bladder, followed by the bile ducts and the colon. The differences had a "z" > 1.645, that is to say, p < 0.05, and so considered statistically significant. CONCLUSIONS: The largest production and publication takes place in the USA and the journal with the greatest influence is the New England. Important studies on method are extremely scarce, random clinical trials representing only 1%.

[Verrucous carcinoma of the anal margin. The Buschke-Loewenstein tumor].

The Buschke-Loewenstein tumour is a rare variety of squamous cell carcinoma of low-grade malignancy; it is located in the external genital organs and the perianal region. We present a new case of this uncommon tumour of short evolution in a 73 years old male patient. Resection was the only treatment, without relapse at 12 months. A review of the literature shows only 13 cases previously published; we comment the human papillomavirus role in their pathogenesis and the various therapies proposed, concluding that the best is surgical treatment.

[Stomach in inguinal-scrotal hernia].

We present two cases of inguinoscrotal hernia that contains stomach, both associated with a chronic obstructive pulmonary disease; one of them is shown with a intermittent gastric obstruction syndrome, the other being a radiological finding in a patient with dispeptic symptoms. The first one died of a respiratory infection, before operation, and the second refused operation because of his scarce symptomatology. A review of the literature shows 60 cases reported including our cases.

[Synchronous intestinal, tonsillar and pulmonary tuberculosis].

OBJECTIVES: To emphasize the unusual synchronous presentation of intestinal, pulmonary and tonsillar tuberculosis in the same patient. CLINICAL CASE: A 43 years old male consults for abdominal pain and alternating episodes of diarrhoea-constipation. Based on radiologic, endoscopic and pathologic studies the diagnosis of Crohn's ileo-cecal disease is achieved and a treatment with salazosulphapyridine and corticosteroid is started. Two months later the patient presents with a tonsilar ulceration that is diagnosed as tuberculosis on biopsy material. At the same time, chest x-rays film reveal active tuberculous lesions, and tuberculous bacili are seen in the sputum. Simultaneously the intestinal disease worsens and complicates with incomplete occlusion that requires a right hemicolectomy. Pathologic study of the specimen shows evident tuberculous lesions. Specific treatment for tuberculosis is started, and the patient remains free of disease one year later. CONCLUSIONS: Due to the increase in the prevalence of tuberculous diseases, we must keep it in mind in the differential diagnosis of intestinal strictures, even though they are suggestive of Crohn's disease, and a radical surgical procedure must also be evaluated.

[Biliary surgery on those over 70: an analysis of 109 cases].

109 patients older than seventy years of age and operated of gallstone disease in our service during a period of 4.5 years are presented. The average age of the series was 78.8 years, with a male/female (M/F) ratio of 1/1.6. 77% of the patients were admitted on an emergency basis due to a complication derived from the gallstone disease they were suffering. Only 39.8% of the patients were previously diagnosed of gallstone disease at the time of admission and 10% presented an associated surgical condition which was treated simultaneously. Overall morbidity of the series was 36%, with a mortality of 2 cases (1.9%).

[Colorectal tuberculosis].

Intestinal tuberculosis has been a clinical rarity in the western world since the tuberculostatic agents were discovered. The most common location of these lesions is usually the ileocecal region, lesions of the transverse colon being much less frequent and perforation of this viscus being exceptional. The etiological diagnosis is usually difficult because there are no specific radiological signs and false negatives are often found in biopsy material obtained by colonoscopy since the process is mainly submucous. This disease is often diagnosed during operation so treatment is usually resection. Should a preoperative diagnosis be made, the picture generally responds to tuberculostatics.
