13. Necrose da mucosa esofágica como complicação da cardiomiotomia à heller para tratamento de megaesôfago chagásico
This article presents a complication of the laparoscopic technique for Heller cardiomyotomy and anterior fundoplication. This procedure is safe and provides excellent relief of disphagia in esophageal achalasia. Nevertheless, there are rare but dangerous complications, such as late active digestive bleeding, presented in this paper which was resistant to con

14. Esophageal striated muscle contractions in patients with Chagas' disease and idiopathic achalasia
Chagas' disease causes degeneration and reduction of the number of intrinsic neurons of the esophageal myenteric plexus, with consequent absent or partial lower esophageal sphincter relaxation and loss of peristalsis in the esophageal body. The impairment of esophageal motility is seen mainly in the distal smooth muscle region. There is no study about esopha

15. Microbiota in chagasic megaesophagus / Microbiota no megaesôfago chagásico.
The stasis of saliva and swallowed food in the esophageal lumen of patients with chagasic megaesophagus causes: (1) bacterial overgrowth in the esophageal lumen, (2) recurring pulmonary aspirations and respiratory infections, (3) increased risk of surgical or endoscopic procedures if perforation occurs by the major possibility of contamination, and (4) the d

16. Upper esophageal sphincter pressure in patients with Chagas' disease and primary achalasia
The most important component of the upper esophageal sphincter (UES) is the cricopharyngeal muscle. During the measurement of sphincter pressure the catheter passed through the sphincter affects the pressure value. In Chagas' disease and primary achalasia there is an esophageal myenteric plexus denervation which may affect UES pressure. We measured the UES p

17. Role of gastrin supersensitivity in the pathogenesis of lower esophageal sphincter hypertension in achalasia
Intraluminal manometric studies were carried out in 19 patients with untreated achalasia and in 20 normals. Lower esophageal sphincter (LES) pressure was 50.5 ±4.6 mm Hg in patients with achalasia as compared with 19.4 ±1.3 mm Hg in the normal group. In both groups, the LES pressure was lowered when exogenous 0.1 N HCl was placed into the stomach. Although

18. A study of swallowing difficulties in first degree relatives of patients with achalasia.
Of 167 patients with achalasia asked to provide details of swallowing difficulties among their first degree relatives, 159 completed the survey (95% response rate). One thousand and twelve first degree relatives were identified, and 14 were reported to have dysphagia including two with reported achalasia. Review of the case notes of these 14 relatives showed

19. Preliminary report of an association between measles virus and achalasia.
Complement fixation tests were performed on sera from 18 patients with achalasia and 12 age- and sex-matched controls against a number of bacterial and viral agents in an attempt to ascertain any association with previous infection or any evidence of an altered immune response. There was a statistically significant increase of antibody titre against measles

20. Acute thoracic inlet obstruction in achalasia of the oesophagus.
A case of acute thoracic inlet obstruction presenting as a rare complication of achalasia is described. The probable mechanism, diagnosis, and management are discussed.

21. Achalasia: outcome of patients treated with intrasphincteric injection of botulinum toxin.
BACKGROUND: To evaluate the safety and clinical efficacy of botulinum toxin (BT) in patients with achalasia followed up for six months. METHODS: Fifty five symptomatic patients with manometrically proven achalasia were included in a multicentre prospective trial. Before and two weeks and two months after intrasphincteric injection of BT, symptoms of dysphagi

22. Physiologic evaluation of esophageal function in patients with achalasia and diffuse esophageal spasm.
To evaluate function of the normal and pathologic esophageal body under more physiologic conditions than those utilized for traditional laboratory testing, manometry was performed before and during eating using a catheter assembly containing three peripheral transducers. Studies were evaluated from seven normal volunteers, 18 typical achalasia patients (eigh

23. Oesophagomyotomy for achalasia of the cardia.
Experience of 48 cases of achalasia of the cardia, treated by oesophagomyotomy, and of three cases of failed 'Heller' operation, treated by jejunal interposition, is recorded. Some technical details and the results are discussed.

24. Current results of surgery for achalasia of the cardia.
Several treatment options are available in the management of achalasia of the cardia. Of a recent series of 14 children, 12 were treated by a modified Heller's myotomy combined with a floppy Nissen fundoplication. Symptoms were dramatically improved in nine during a mean follow up period of 3.9 years. Recurrent oesophageal pain was the most resistant symptom
