[Gastrointestinal bleeding caused by small bowel leiomyosarcoma]. / Hemorragia digestiva por leiomiosarcoma de intestino delgado.

The small bowel leiomyosarcoma is a infrequent tumour in the clinical practice. We report the case of a 50 year old male admitted to the hospital on two occasions for gastrointestinal bleeding. On the second occasion a push enteroscopy located in jejunum a tumour. The pathologic diagnosis was a low grade jejunal leiomyosarcoma. The patient required a surgical intervention with resection of the affected portion of the jejunum.

[Evaluation and improvement in the information of the patients who carry out a digestive endoscopy]. / Evaluación y mejora en la información de los pacientes que se realizan una endoscopia.

INTRODUCTION: The information is an important part of the attendance process though in occasions it can be inadequate or deficient. AIM: We detect an opportunity of improvement in the inadequate information of the patients who carry out an endoscopia. The aim is to evaluate and to improve the quality of the information. METHOD: We realize the first evaluation with 100 patients proceeding from consultations, detecting ignorance of the technology. Actions of improvement are applied, for 4 months, to realize the second evaluation, with the same number of patients and to evaluate improvement with regard to the situation of item. RESULTS: A deficit of information has been detected in the moment to indicate the endoscopia (little information contributed by the doctor prescriptor and in an important number of cases informed assent was not contributed) and after realizing the test, not contributing recommendations. We prioritize our action to this level with measures of improvement and after a new evaluation, a significant improvement decides in these situations. CONCLUSIONS: The studies of qualit level allow us to detect deficit situations and to improve situations in the services of health.

[Multiple angiodysplasia of the small intestine. A diagnostic and therapeutic challenge]. / Angiodisplasia múltiple de intestino delgado. Un reto diagnóstico y terapéutico.

Small bowel bleeding is infrequent and presents a challenge to the clinician. Approximately 30-40% of gastrointestinal bleeding localized in the small bowel is due to angiodysplasia, a vascular malformation. We present the case of a patient with multiple angiodysplasia of the small bowel who required push enteroscopy and capsule endoscopy to establish the diagnosis. Treatment with subcutaneous octreotide was successful. In conclusion, in doubtful cases or in patients with persistent hemorrhage, capsule endoscopy can improve the diagnostic yield of enteroscopy in bleeding gastrointestinal vascular lesions such as angiodysplasia. Endoscopic treatment (laser coagulation) and drug therapy (somatostatin or analogs) are valid alternatives in inoperable or non-resectable cases.

Short myotomy for vigorous achalasia.

Vigorous achalasia has been considered an indication for surgery, in which a thoracic approach is recommended for extending the myotomy along the whole of the oesophageal body to the point where manometry shows high-amplitude waves. Clinical results and postoperative manometric findings in 16 patients with vigorous achalasia undergoing abdominal surgery with myotomy limited to the lower oesophageal sphincter (LOS) were analysed to assess whether extended myotomy is necessary in surgery for this form of achalasia. The clinical results were excellent or good in all cases. Surgery induced a significant decrease (P < 0.01) in the diameter of the oesophagus as determined radiologically. The most significant postoperative manometric changes were a decrease in the resting pressure of the LOS and oesophageal body, a lowering of wave amplitude at all levels of the oesophagus, and a reduction in the proportion of repetitive waves. The results suggest that vigorous achalasia can be treated surgically in the same way as classical achalasia and question, at least from a therapeutic viewpoint, the use of the term vigorous achalasia.

Management of the perineal wound following abdominoperineal resection: prospective study of three methods.

A prospective study was made of three procedures for treating the perineal wound and presacral cavity in 102 patients undergoing abdominoperineal excision for cancer of the rectum: (1) packing of the presacral space after suture of the pelvic peritoneum; (2) suture of the pelvic peritoneum and perineal wound, leaving two drains through the perineum; and (3) no suture of the pelvic peritoneum, and primary closure of the perineal wound, leaving drains through the abdomen for physiological saline irrigation. The parameters analysed were incidence of infection, primary healing of the perineum, extraperineal complications and mean hospital stay. Primary healing of the perineum was best with method 3, and overall incidence of infection highest with method 2. There were no differences between the methods with regard to extraperineal complications. Hospital stay was shortest with method 3.

[Mallory-Weiss syndrome as etiologic factor of upper gastrointestinal hemorrhage. A review of 142 cases]. / El síndrome de Mallory-Weiss como factor etiológico en la hemorragia digestiva alta. Revisión de 142 casos.

The diagnosis of Mallory-Weiss syndrome was made in 142 patients with upper gastrointestinal haemorrhage by early endoscopy. These patients represent 5.16% of all patients with haemorrhage treated in our unit over a period of ten years. Emergency surgery was needed in 13 due to persistent haemorrhage. In the remaining 129, conservative management sufficed to stop the bleeding. All patients receiving medical therapy survived while one of the surgically treated patients died of pulmonary thromboembolism in the early postoperative period.

[Early cancer of the stomach. Review of 29 cases]. / Cáncer gástrico precoz. Revisión de 29 casos.

A series of 29 patients with early gastric cancer operated on in our department over a period of 10 years is presented; this figure represents 9.10% of total number of gastric cancers. The most common symptom was epigastric pain, present in 51.72% of cases. Diagnosis was established by endoscopy and biopsy in 96.5% patients. Treatment was subtotal gastrectomy in 28 cases; most lesions (24) were located in the distal third of the stomach. Lesion was intramucosal in 44.8% of cases; in 55.17% there was infiltration of the submucosal layer and only 13.8% of tumors presented lymph node metastases. Macroscopically the most common pattern of the lesions was the ulcerated type. All patients have been followed up at least 4 years; of them died: one of carcinoma of the bladder and three of chronic respiratory failure. There were no recurrences of the gastric lesion and the 5 years actuarial survival was 84.32%.

[Quantification of gastro-esophageal reflux in Barrett's esophagus]. / Cuantificación del reflujo gastro-esofágico en el esófago de Barrett.

In the present paper we analyze the importance of gastro-oesophageal reflux in 20 patients with Barrett's oesophagus and in 20 patients with esophagitis without Barrett's mucosa; ten of this last group had mild esophagitis and ten severe inflammatory changes. In all the cases the oesophageal pH was measured during 24 hours; the results showed that although the reflux was more important in the group of patients with Barrett's esophagus than in the whole group of patients with esophagitis without Barrett's esophagus, figures were similar in the group with severe oesophagitis and the group with Barrett's oesophagus. We conclude that the pathogenesis of Barrett's esophagus includes factors other than gastroesophageal reflux.

[Barrett esophagus: epidemiologic data and risk of becoming malignant]. / Esófago de Barrett: datos epidemiológicos y riesgo de malignización.

A series is presented of 152 patients diagnosed over a 9-year period by endoscopy and biopsy as Barrett's esophagus. We analyzed epidemiological data and the risk of malignancy, and calculated the prevalence and incidence in our series.
