Esophagoenteral stents in patients with recurrent gastric adenocarcinoma.

One of the problems that can appear in patients with total gastrectomy for adenocarcinoma with esophagoenteral anastomosis is the appearance of a stenosis of the anastomosis. These stenosis are frequently malignant due to relapse of neoplasia. The therapeutic possibilities available are the surgical bypass or palliative treatment. There is very little experience described in the literature (21 cases) on the placing of self-expandable metal stents as a palliative treatment for the symptoms of stenosis.We present our experience of 3 patients, in whom 4 esophageal stents were fitted (1 covered and 3 uncovered) with good results. The dysphagia disappeared or improved, it allowed the ingestion of a soft diet and meant an improvement in the quality of life and at the same time stopped the weight loss. It seems an effective palliative treatment as a treatment for dysphagia in patients with tumoral relapse in the anastomosis of total gastrectomies.

Prótesis esofagoenterales en pacientes con recidiva de adenocarcinoma gástrico / Esophagoenteral stents in patients with recurrent gastric adenocarcinoma

Uno de los problemas que puede aparecer en los pacientescon gastrectomía total por adenocarcinoma con anastomosis esofagoenterales la aparición de estenosis de la anastomosis o próximaa ella. Estas estenosis con frecuencia son malignas debido a laaparición de recidiva en la neoplasia. Las posibilidades terapéuticasde las que disponemos son el bypass quirúrgico o bien el tratamientopaliativo. Existe muy poca experiencia descrita en la literatura(21 casos) sobre la colocación de prótesis metálicasautoexpandibles como tratamiento paliativo de los síntomas de laestenosis.Presentamos nuestra experiencia en 3 pacientes, en los que secolocaron 4 prótesis esofágicas (1 recubierta y 3 no recubiertas)con buenos resultados. Desapareció o mejoró la disfagia, permitióla ingesta de dieta blanda y supuso una mejora en la calidad devida a la vez que impide la pérdida ponderal. Parece un tratamientopaliativo eficaz como tratamiento de la disfagia en pacientescon recidiva tumoral en la anastomosis de las gastrectomías totales

Tratamiento del esófago de Barrett en el siglo XXI: controversias y perspectivas futuras / Treatment of Barrett´s esophagus in the century XXI: controversies and future perspectives

El esófago de Barrett continua siendo hoy en día, una de las patologías digestivas que más interés suscita en todas las reuniones y congresos de la especialidad, a pesar de haber sido descrito hace ya 50 años. Su definición ha cambiado; se ha reconocido su predisposición al desarrollo del adenocarcinoma esofágico; se ha desarrollado un tratamiento más efectivo en el control del reflujo gastroesofágico (inhibidores de la bomba de protones v/s fundusplicatura laparoscópica); se han protocolizado programas de vigilancia sobre todo en pacientes con displasia; se están investigando nuevas estrategias terapéuticas. A pesar de ello, todavía persisten numerosas controversias. El conocimiento exacto y preciso de la fisiopatología constituye la base del tratamiento y la prevención de la enfermedad por reflujo gastroesofágico y sus complicaciones (AU)

[Treatment of Barrett esophagus in the XXI century: controversies and future perspectives]. / Tratamiento del esófago de Barrett en el siglo XXI: controversias y perspectivas futuras.

Barrett's esophagus is today, one of the digestive pathologies that raises more interest in all the meetings and congresses of the specialty, in spite of have been described 50 years ago. The definition has changed; the rising incidence of adenocarcinoma has been recognized; a most effective therapy to control gastroesophageal reflux has been developed (proton pump inhibitor v/s laparoscopic fundoplication); appropriate surveillance intervals of patients with dysplasia have been protocolized; new treatment strategies are being investigating. Although, numerous controversies still persist. The exact and accurate knowledge of physiopathology constitutes the base of treatment and prevention for gastroesophageal reflux disease and their complications.

Influence of physical factors on the development of gastroesophageal reflux in man: analysis by means of an experimental mechanical model.

In this paper, the isolated influence of physical factors on the development of gastroesophageal reflux in man is analyzed by means of a mechanical model. We evaluate the influence of gravity, intraabdominal pressure, intrathoracic pressure, transmission of intraabdominal pressure to the high pressure zone, filling volume of the stomach, and the existence of a high pressure zone on the appearance of gastroesophageal reflux. PH-metry is used to record the episodes of reflux in the model. We wish to demonstrate the importance of gravity and intraabdominal pressure in the production of reflux. Intrathoracic pressure acts as an antireflux mechanism only when associated with a zone of high pressure. The intraabdominal pressure may be transmitted to the high pressure zone as a purely mechanical effect and the greater gastric filling volume may, when associated with the intraabdominal pressure, facilitate reflux without physical changes in the high pressure zone (the equivalent of a reduction in the length of the lower esophageal sphincter in man). We conclude that this model may help to explain the influence of the physical factors mentioned above on the development of gastroesophageal reflux in man.

Recurrent acute pancreatitis as a complication of cystic fibrosis: report of one case treated surgically.

We present the case of a young woman previously diagnosed with cystic fibrosis (CF) manifested primarily by respiratory symptoms and pancreatic exocrine insufficiency. Only 0.5% of these patients suffer from episodes of recurrent acute pancreatitis, the majority of which respond to conservative treatment. In this case, recurrent episodes of acute pancreatitis made it necessary to perform a surgical pancreatic drainage procedure.

[The surgical treatment of esophageal leiomyomas: a report of 9 cases and a review of the literature]. / Tratamiento quirúrgico de los leiomiomas esofágicos: aportación de nueve casos y revisión de la literatura.

We report a series of 9 leiomyomas of the esophagus treated surgically. We review the literature, emphasizing diagnostic and therapeutic aspects, calling special attention to the good results obtained by submucosal enucleation of the tumor.

Hepatic myelolipoma: new case and review of the literature.

We present a case of hepatic myelolipoma that was treated by performing a right hepatic lobectomy. These tumors are very uncommon and present great problems for the pre-operative diagnostic evaluation. Currently, the diagnosis is essentially histopathological with a definitive diagnosis being made by immunocytochemical staining. We have found no reports on this type of tumor in the Spanish literature; a review of the published cases confirms our observations and conclusions regarding hepatic myelolipoma.

Results of surgery for cancer of the rectum with sphincter conservation. A randomized study on instrumental versus manual anastomosis.

We present results obtained in a group of patients included in a randomized study from 1979 to 1985 for evaluation of mechanical anastomosis after anterior resection for cancer of the rectum; 113 patients were operated on, 58 with manual and 55 with instrumental anastomosis. There was no significant difference in morbidity or mortality between the groups. The incidence of anastomotic fistulas (clinical and subclinical) was similar (12% vs. 15%), although a large number of tumors in the lower third of rectum was treated by manual anastomosis. Concerning late complications, more stenoses, although mainly asymptomatic, were detected after instrumental anastomosis (15% vs. 6%). The incidence of local recurrence within 3 years was quite similar in the 2 groups (about 15%), and usually occurred in patients who already had generalized disease.

Left gastric arteriovenous fistula after selective distal splenorenal shunt.

We present the case of a 64-year-old alcoholic who had suffered two episodes of hemorrhage from esophageal varices. For control of variceal hemorrhage, he underwent a distal splenorenal shunt. His immediate postoperative course was complicated by the development of marked ascites and intermittent episodes of encephalopathy. Routine postoperative angiography was performed after 4 months and demonstrated a fistula between the left gastric artery and vein. Patency of the shunt was demonstrated by direct percutaneous splenoportography. Two months after this admission, the patient was readmitted with the complaints of anorexia and nausea. Marked encephalopathy was noted. Eight hours following admission, he developed acute abdominal distention and hypotension. An abdominal tap revealed bloody fluid, and the patient was immediately prepared for transport to the operating room. He suffered cardiac arrest during transport, and all efforts at resuscitation were unsuccessful. Although a postmortem examination was not performed, it is suspected the arteriovenous fistula resulted in severe portal venous hypertension leading to intraperitoneal rupture of one of the affected veins, producing a massive hemoperitoneum.
