[Nonelective colorectal surgery. Does age determine the results?].

OBJECTIVE: To evaluate the influence of age on the morbi-mortality after non-elective colorectal surgery. DESIGN: Retrospective analysis. SUBJECTS: 150 consecutive patients who underwent non-elective colorectal surgery between 1986 and 1992 [65 patients aged under 70 years (Group I)] and 85 patients aged 70 years or over (Group II)]. RESULTS: Using multiple regression analysis we have found: 1) Mortality is determined by the presence of associated risk factors (p < 0.001 tv = 4.11), the presence of peritonitis (p < 0.05 tv = 2.08) and by the admission-operation interval (p < 0.05 tv = 2.10). 2) Overall morbidity increases with age (p < 0.01, tv = 3.22) and the benign nature of the colorectal disease (p < 0.05, tv = 2.00). CONCLUSION: Age does not influence mortality in non-elective colorectal surgery even though it is a determinant risk factor in morbidity increase.

[Idiopathic ulcer of the small intestine].

Two cases of multiple idiopathic ulcers of the small intestine are reported, which were found in two aged patients with a significant history of vascular pathology. Despite this, the pathological examination of the surgical specimens could not demonstrate a vascular origin of such lesions.

[Appendicular invagination].

Two cases of intussusception of the appendix are reported. The first case stands out for its rarity, corresponding exclusively to intussusception of appendicular mucosa. The second case was due to cystoadenoma of the appendix. Both cases were treated by right hemicolectomy due to the difficulty of diagnosing the condition.

[Digestive hemorrhage caused by vascular malformation (Rendu-Osler-Weber). A diagnostic and therapeutic challenge].

We present a case of gastrointestinal bleeding due to vascular malformation (Osler-Weber-Rendu disease), without cutaneous manifestations but with mucous manifestations and familiar and personal history of epistaxis. Until diagnosis, the patient underwent multiple radiologic and endoscopic tests and two surgical procedures. We would underline the diagnostic and therapeutic difficulty of recurrent gastrointestinal bleeding secondary to vascular malformation.

[Anisakiasis as a cause of acute appendicitis and rheumatologic picture: the first case in medical literature].

We report a case of acute abdomen due to appendicular lumen occlusion by anisakis larvae. This is the first case of human anisakiasis known in Spain, and the first case of acute appendicitis, in the medical World literature, produced by this nemathode. The association of myalgias and arthralgias stands out, being in this aspect the second case found the in medical litterature.
