[Primary gastric lymphomas]. / Linfomas gástricos primarios.

A series of 13 patients with primary gastric lymphoma treated between 1981 and 1990 are presented. Primary gastric lymphoma made up 4.8% of all gastric tumors treated during this period of time. Histologically, there were 3 lymphoplasmocytoid and 3 centroblastic forms (according to Kiel's classification) followed by 2 lymphocytic and 2 centrocytic-centroblastic. According to Mushoff's classification. 4 patients belonged to stage I E, 3 to II E1, 3 to II E2, 2 to III E, and one patient to stage IV E. In all cases gastrectomy was performed (9 subtotal and 4 total) although 3 out the former were palliative (23%). The operative morbidity was 30.7% and the mortality 7.7%. Seven patients received additional treatment with chemotherapy. Survival after 2 years was 70%.

[Acute appendicitis in the elderly patient]. / Apendicitis aguda en el anciano.

Presentation of 55 patients aged more than 65 years, appendectomized with the diagnosis of acute appendicitis. After histological study, we saw 6 normal cecal appendixes (10.9%), so the real number of acute appendicitis operated was 49 out of 435 (11.2%) interventions. The clinical history was typical in most of the patients and, nevertheless, we noticed a diagnostic delay greater than 24 hours in 31 (63.2%), and greater than 48 hours in 17 patients (34.6%). We verified the existence of a high percentage of perforated appendicitis (36.7%) closely related to a long evolution time, not being able to show, in the group studied, an increase of early appendix perforations in comparison with the rest. These results suggest that the high morbidity of acute appendicitis in old patients is due, to a great extent, to a delay in the performance of the appendectomy.
