[Zenker diverticulum: therapeutic approach]

BACKGROUND

Pharyngoesophageal or Zenker diverticula are a few frequent pathology that could represent between 1 and 3% of the patients with dysphagia and their physiopathology even at present is scarcity clear.

OBJECTIVE

Therapeutic procedures results about this pathology were analyzed.

SETTING

Caraffa and Sucre Clinic.

DESIGN

Retrospective observational study.

METHOD

It analyzed 13 patients operated by Zenker diverticula 9 of which were male and 4 were female sex with an average age of 55.6 years. Dysphagia occurred in 100% of the cases. Besides clinical finding the diagnosis was made evident by esophageal X-ray with contrast medium and endoscopy. Diverticulectomy by one stage through a left cervicotomy was the surgical procedure of choice.

RESULTS

There was no surgical mortality. Related with morbility 2 patients presented fistulas managed medically and in other 2 patients abscesses of surgical wound occurred. The follow-up was carried on 6 months, 4 and 7 years respectively without relapses and with a good posterior evolution.

CONCLUSIONS

Based on our short experience and the results attained we think the treatment of Zenker or pharyngoesophageal diverticulum by diverticulectomy through a left cervicotomy is safe and effective procedure to control this pathology.

[Value of the nuclear magnetic cholangio resonance in the study of the patient with jaundice]

This report analyse the results about forty three (43) patients, thirty six (36) of which showed an extrahepatic obstructive biliary Syndrome was made evident by ultrasonography, five (5) with a cholecistolithiasis and doubtful history of jaundice were evaluated to carry out a video-surgery procedure and two (2) patients whom hepatic-yeyunostomy had been practiced, a control of anastomosis in postoperative period was required. Nuclear Magnetic Resonance and Operative Cholangiography findings were correlated and afterward with the anatomopathological studies when they arrived. In all cases the Nuclear Magnetic Cholangio Resonance (NMCR) let us prove the diagnosis of extrahepatic biliary obstruction determining with precision furthermore the topographical site of the lesion. Respecting the aetiology of obstruction, NMCR was accurate in 34 out of 36 cases (94.4%). In conclusion Cholangio-Resonance is an excellent diagnostic method to evaluate biliary ductal system including anatomic changes. However, there are some limitations yet in order to determine the aetiology of lesions about extrahepatic biliary via extremes. We emphasize its features such as non-invasive, little operating dependent, and without morbimortality that become it as a method of choice to study the biliary via from a diagnostic viewpoint.
