OBJECTIVE To implement a fast-track (FT) protocol in a colorectal surgery unit, checking its safety when applied to patients subjected to elective colorectal surgery, by evaluating the differences in morbidity and hospital stay compared to a control group with traditional care. We also analyse the functional recovery of the FT group. MATERIAL AND METHOD A(More)
OBJECTIVE to evaluate the possible existence of the so-called <<Roux-en-Y syndrome>> in a group of 21 patients who underwent surgery to correct postoperative alkaline reflux gastritis. METHODS the study group consisted of 15 men and 6 women (mean age 39.2 years). All had undergone Billroth II subtotal gastrectomy (20 for ulcer and 1 for gastric cancer).(More)
OBJECTIVE To analyze the results obtained with a "one-stop" specialty service designed as part of a collaborative program involving primary and specialized care in order to improve communication between levels of care and reduce the delay in referral and surgical treatment for patients eligible for outpatient surgery. DESIGN Prospective, descriptive,(More)
The authors report a case of carcinoma arising in a longstanding Zenker's diverticulum, in a 66 years old man that refused surgical treatment for 25 years. Three months prior to his admission to our hospital, an exacerbation of his dysphagia, which became severe, was observed; and so was regurgitation, with passage to the airway during swallowing or when(More)
A retrospective analysis is made of the risk factors in 229 patients admitted to hospital with hemorrhage from peptic ulcer. The factors that have been studied are: 1) age. 2) type of ulcer lesion. 3) associated disease. 4) antiinflammatory intake. 5) prior ulcer symptoms. 6) intensity and outcome of the bleeding episode. 7) endoscopic findings. 8)(More)
OBJECTIVE We studied the effect of prophylaxis for thromboembolism with low-molecular-weight heparin (LMWH) during hospitalization on the biological hemostasis system in patients who had undergone laparoscopic cholecystectomy. METHODS This was a prospective paired cohort study without a control group (i.e., a before-after study). The subjects were 20(More)
Changes in serum gastrin levels in the late postoperative period have been studied in 24 patients with non-stenotic duodenal ulcer who underwent proximal gastric vagotomy. Twenty healthy volunteers were used as a control group. Serum gastrin levels were determined under basal conditions and after a high protein meal stimulation. Both measurements were done(More)
In order to determine the causes of postvagotomy dysphagia, we examined microscopic changes in the lower esophagus after a proximal gastric vagotomy. Forty dogs were divided into 4 groups (n = 10). Group I was used as control. In group II, the effect of denervation was studied by means of transthoracic vagotomy. In group III, the effect of mechanical(More)
