A patient with a jejunal leiomyoblastoma presented with lower gastrointestinal haemorrhage, a most unusual occurrence according to the literature. The provisional diagnosis was made by arteriography and confirmed pathologically. The characteristics of these tumours are analyzed and the management discussed.
The authors present a case of hemangiopericytoma of the rectal mesentery, this is an uncommon type of vascular tumor, exceptional in this localization. We analyze the difficulty of a preoperative diagnosis, the lack of specificity of the clinical signs and the importance of the radical resection linked to the biological aggressiveness and the frequency of local recurrences and distant metastases.
The authors report a case of gastric lipoma which was discovered because of severe upper gastrointestinal bleeding. The entity is seldom reported in the literature; only 17 cases have been reported in our country. The diagnostic possibilities are analyzed. In most cases they only confirm the diagnosis of a benign tumour and pathological verification is necessary. Surgical treatment is recommended in the light of the frequent complications of this tumor.
We compared the measurements obtained with different systems presently used to study the pressure characteristics of the anal channel (an open perfusion probe, a closed perfusion probe and a microtransducer). We also studied rectal sensitivity to distention in an attempt to define the exactness and reliability of the measurements made with these different techniques. The results indicate that although the measurements obtained vary with the diameter of the catheters used, the differences were not statistically significant. In contrast, the maximum tolerated volume of patients is greater with a slow and continuous rhythm of infusion than when saline is infused rapidly and in boluses. The published literature is reviewed and results are discussed, as well as the advantages and disadvantages of different methods.

A case of splenic hydatid cyst perforating into stomach is reported, only three similar cases being documented in the literature. Frequency, symptomatology, diagnostic methods and therapy of splenic hydatid cyst and of this strange complication are discussed.

Study of a sample of surgical patients, evaluating their preoperative nutritional state using anthropometric parameters and normality reference tables used by most authors and those used in Spain. Results obtained with both were compared. A significant difference was found (p < F0.001) in the results using one or the other table, and this leads us to question the universal use of these tables.
The preoperative nutritional state of a sample of surgical patients was studied, relating this to postoperative complications and mortality. No significant relation was found to exist between the anthropometric parameters used and the complications and/or mortality, which was seen to have little prognostic value.
Four cases of intestinal intussusception in adults are presented. Etiology was not common in all of them. Frequency, clinic presentation and diagnostic approach are discussed. A emergency right colectomy was performed in all of them.
