A 14-year-old girl was admitted to our hospital for treatment of abdominal pain after an attempt to commit suicide by swallowing a caustic soda solution. Severe esophageal stricture following corrosive esophagitis occurred 2 weeks after admission. First, we tried to dilate the stenotic esophagus by using an esophageal bougie, but it was not effective and was also painful, and the treatment was stopped. Next, we tried endoscopic balloon dilation. This procedure was less painful and more effective for dilating the stenotic esophagus than was the bougie. At first, we used a pneumatic balloon and injected a steroid locally under the mucosal layer after dilation. The same procedure was continued in the outpatient clinic, but each interval of the procedures, about 3 weeks, was not changed for about 1 year. After 1 year of consecutive trials of frequent dilatation using a pneumatic balloon, the type of balloon was changed to a hydrostatic type. Three months after changing the type of balloon, treatment with tranilast, which was expected to be effective for prevention of restenosis, was started instead of steroid injection to the stenotic portion. After starting tranilast treatment, the interval of dilation became longer and the stricture itself gradually became dilated. Twenty-one months later, the interval of dilation was 3–4 months and oral intake had improved greatly. We therefore concluded that frequent endoscopic balloon dilation is effective for dilating stenosis after corrosive esophagitis. In addition, this case suggests that treatment with tranilast could be effective for preventing esophageal restenosis after balloon dilation. 相似文献

Objectives: To describe the technique of pneumatic dilation for achalasia without fluoroscopic guidance and to assess its safety and efficacy. Methods: Twenty-seven consecutive patients who underwent pneumatic dilation with the Rigiflex achalasia balloon under direct endoscopic visnalization were reviewed. The balloon was passed into the stomach over a guidewire, withdrawn across the gastroesophageal junction, and dilated with the endoscope positioned proximally. Patients wore graded pre- and posttreatment on the frequency of dysphagia, daytime regurgitation, nighttime symptoms, chest pain, and heartburn. Response was assessed by the Improvement in dysphagia frequency. Results: Twenty-seven patients (16 females, 11 males; mean age 54.0 yr) underwent 30 pneumatic dilations. The 30-mm balloon was used in most cases (67%). The mean postdilation follow-up was 21.1 months (1.5–57.4 months). The range of inflation pressures was 8–18 psi (median 15 psi), and the duration of inflation was 30–120 s (median 90 s). Eighteen of 27 patients (67%) had excellent or good results, six (22%) had fair results, and three (11%) had poor results. The outcome of pneumatic dilation was successful in 78% of patients after a single dilation and in 89% of patients overall. There were no perforations related to balloon inflation. Conclusions: The Rigiflex balloon can be successfully positioned across the gastroesophageal junction and dilated under direct endoscopic observation. Pneumatic dilation for achalasia can therefore be performed simply, safely, and effectively without the use of fluoroscopy. 相似文献

Graded Pneumatic Dilation using Rigiflex Achalasia Dilators in Patients with Primary Esophageal Achalasia 总被引:14,自引:0,他引:14
Shailesh C. Kadakia M.D. F.A.C.P. F.A.C.G. F.C.C.P. Roy K. H. Wong M.D. F.A.C.P. F.A.C.G. 《The American journal of gastroenterology》1993,88(1):34-38
Pneumatic dilation is the initial therapy for primary esophageal achalasia. Recently, polyethylene balloon (Rigiflex) dilators have been used with varying success and complication rate. We performed a total of 47 dilations in 29 consecutive patients with achalasia using the Rigiflex dilators. The 3.0-cm balloon was always used first. If there was no symptomatic response, a 3.5-cm balloon was used after 4–8 wk. If there was still no symptomatic response after 4-8 wk, a 4.0-cm dilator was used. Eighteen (62%) patients were successfully dilated with a 3.0-cm balloon only. Of 11 patients not responding to a 3.0-cm balloon, five were dilated successfully with a 3.5-cm balloon. Of six patients not responding to a 3.5-cm balloon, four were successfully dilated with a 4.0-cm balloon dilator. Two patients eventually required surgery. The overall success with Rigiflex balloon dilator was achieved in 27 of 29 (93%) patients. There were no complications. We conclude that pneumatic dilation for esophageal achalasia performed in a graded fashion starting with Rigiflex 3.0-cm balloon dilator has a high success rate without complications in patients with achalasia. 相似文献

Achalasia is a disorder characterized by abnormal motility of the esophageal body and the lower esophageal sphincter, resulting in dysphagia, regurgitation, and chest pain. Treatment options for achalasia include Botulinum toxin injection, pneumatic balloon dilation, and surgical esophagomyotomy. The aim of this study was to determine the cost-effectiveness of these three strategies in the treatment of achalasia in adults. We constructed a Markov cost-effectiveness model comparing Botox injection, pneumatic balloon dilation, and laparoscopic esophagomyotomy as initial treatments of achalasia. Costs and probabilities were derived from the published literature. The utility for symptomatic achalasia was derived from a sample of patients with achalasia. Sensitivity analyses were performed. Over a five-year time horizon, pneumatic dilation was the most cost-effective treatment strategy for achalasia, with an incremental cost-effectiveness ratio of $1348 per quality-adjusted life-year compared to Botox. Although laparoscopic esophagomyotomy was more effective than the other treatment options, it was not cost-effective because of its high initial cost. In conclusion, pneumatic dilation is the most cost-effective treatment option for adults with achalasia. Further studies should examine the long-term relapse rates following treatment with Botox and more precisely determine the quality of life of symptomatic achalasia. 相似文献

Two unusual cases of achalasia with endoscopic and histologic documentation of Barrett's esophagus are presented. One patient had Barrett's esophagus at the time of initial endoscopy for achalasia, before any treatment. The other patient developed specialized columnar epithelia in the esophagus after treatment with pneumatic dilation. Each patient had evidence of low-grade dysplasia. Including these two patients, 30 cases of Barrett's esophagus in patients with achalasia have been reported in the literature. In 73% (22 of 30) of the cases, Barrett's esophagus was detected after esophagomyotomy. In 20% (6 of 30) of the cases of achalasia and Barrett's esophagus, adenocarcinoma developed. The current two cases are unusual because Barrett's esophagus in achalasia generally develops from gastroesophageal reflux after esophagomyotomy. No other patients have been reported to develop Barrett's esophagus after pneumatic dilation alone. Patients with achalasia and Barrett's esophagus may be at a particularly high risk for developing dysplasia and adenocarcinoma. 相似文献

Levels of muscle enzymes in the serum after esophageal pneumatic dilation in patients with achalasia
N. A. Kimchi Y. Ron D. Abramowich H. Shirin E. Scapa Y. Avni 《Diseases of the esophagus》2005,18(5):332-334
The success rate of pneumatic dilation of the esophagus in patients with achalasia is variable. We aim to assess whether levels of muscle enzymes in the serum are useful for predicting the efficacy of this procedure. Consecutive adults with symptomatic achalasia treated with pneumatic dilation were included. Blood samples were taken immediately before the procedure and after 12, 24 and 32 h. Clinical efficacy of the pneumatic dilation was evaluated on the basis of a symptom score defined prior to, and 2 months after the procedure. Eleven patients underwent 13 pneumatic dilations. In nine patients this was the first dilation attempt. Ten dilations were clinically effective. The study was discontinued after enzyme levels did not show a trend of increase in any of our patients. Moreover, a statistically significant unexpected decrease in creatine phosphokinase values was found 12 h after the procedure, among the 10 successful dilations. We believe that levels of muscle enzymes in the serum cannot predict the efficacy of pneumatic dilation in patients with achalasia. 相似文献

Achalasia is a primary motor disorder of the esophagus, in which esophageal emptying is impaired.Diagnosis of achalasia is based on clinical findings. The diagnosis is confirmed by radiographic, endoscopic,and manometric evaluations. Several treatments for achalasia have been introduced. We searched the PubMed Database for original articles and metaanalyses about achalasia to summarize the current knowledge regarding this disease, with particular focus on different procedures that are used for treatment of achalasia. We also report the Iranian experience of treatment of this disease, since it could be considered as a model for mediumresource countries. Myotomy,particularly laparoscopic myotomy with fundoplication,is the most effective treatment for achalasia.Compared to other treatments, however, the initial cost of myotomy is usually higher and the recovery period is longer. When performing myotomy is not indicated or not possible, graded pneumatic dilation with slow rate of balloon inflation seems to be an effective and safe initial alternative. Injection of botulinum toxin into the lower esophageal sphincter before pneumatic dilation may increase remission rates. However, this needs to be confirmed in further studies. Due to lack of adequate information regarding the role of expandable stents in the treatment of achalasia, insertion of stents does not currently seem to be a recommended treatment. In summary, laparoscopic myotomy can be considered as the procedure of choice for treatment of achalasia. Graded pneumatic dilation is an effective alternative when the performance of myotomy is not possible for any reason. 相似文献

BACKGROUND: Pneumatic balloon dilation is a popular method of treating patients with achalasia cardia. It may be useful to know the factors that predict response to this treatment. AIM: To determine predictors of outcome following pneumatic balloon dilation in patients with achalasia cardia. METHODS: Records of 62 patients who had undergone pneumatic dilation using Rigiflex balloon dilators (Boston Scientific, Boston, MA, USA) were reviewed. Follow-up data were available for 52 patients. Data from patients with and without improvement in symptoms were compared. RESULTS: Of the 52 patients (age mean 44 [range 11-68] years; 27 male; median symptom duration 20 [4-90] months], 42 (81%) patients had response in symptoms after balloon dilatation. On univariate analysis, the responders more often had age> 40 years (26/42 [62%] versus 1/10 [10%], p=0.003), and less often had lower esophageal sphincter pressure> 50 mmHg (8/10 [80%] versus 10/42 [24%], p=0.0007) and mid-esophageal body hypocontraction (7/10 [70%] versus 12/24 [29%] p=0.01) than the non-responders.

Postvagotomy dysphagia is typically a temporary phenomenon but a small subgroup of patients appear to develop irreversible motility disorders of the esophagus. Two patients are reported with persistent symptomatic esophageal dysfunction demonstrated by modern hydraulic infusion technics. Both intially lost weight rapidly and then stabilized. The distal esophagus of both was greatly dilated but in one patient, lower esophageal sphincter pressure was normal. Aperistalsis with diminished motor activity was present throughout the body of the esophagus. Dysphagia and objective esophageal abnormalities were refractory to dilations with simple mercury bougies in one patient whose condition was improved by treatment with pneumatic dilation. The cause of this unusual complication is unknown but may involve a nonneoplastic form of secondary achalasia. 相似文献

In a retrospective study, 33 achalasia patients were treated with dilation therapy using large diameter mercury bougienage (mean, 56 French) and/or pneumatic balloon dilation. Mean follow-up time was 35 months. Mercury bougienage, performed in 20 patients, was successful in 10 (50%) with no complications. Pneumatic dilation was performed as initial therapy or in those having failed previous pharmacologic therapy and/or bougienage. A successful response was achieved in 19 of 23 patients (83%), with a 3.2% complication rate. In addition, in four patients with eventual recurrence of symptoms after initial pneumatic dilation, bougienage was used as a successful alternative to repeat pneumatic treatment. The combined efficacy of both forms of dilation was 88% with a complication rate of 1.4%. These data indicate that mercury bougienage should be considered initial therapy for achalasia in view of its simplicity, safety, and acceptable efficacy, followed by pneumatic dilation if bougienage is unsuccessful. Bougienage also may be considered if eventual recurrent symptoms develop after initially successful pneumatic dilation. Surgery should be utilized only if dilation therapy fails to achieve a satisfactory response. 相似文献

Objective: To conduct a retrospective analysis of one center's experience with treating achalasia over 4 yr with skilled gastroenterologists using primarily the Rigiflex halloon dilator and with a senior surgeon performing Heller myotomies. Methods: Newly diagnosed cases of achalasia were identified hy a computer search of hospital records. Charts were reviewed for the presence/ severity of dysphagia, regurgitation, heartburn, and chest pain. Weight loss was also recorded. Esophageal manometries and barium swallows were reviewed. Choice of treatment was made freely by patients. With an a priori definition of success, follow-up was conducted by telephone interviews. Results: A total of 45 achalasia patients (mean age, 46 yr; 32 females, 13 males) were identified with a symptoms-frequency as follows: dysphagia, 100%; regurgitation, 78%; heartburn, 50%; and chest pain, 42%. Mean weight loss was 17.5 pounds. Primary treatment was pneumatic dilation in 36 patients and surgery in nine patients. In a total of 45 pneumatic dilations, three (6.6%) were complicated by perforation. Five (14%) patients required repeat dilation. Mean duration of follow-up for pneumatic dilation and surgery was 27 months and 20.8 months, respectively. The overall excellent-good success rates were: pneumatic dilation 88% and surgery 89%. In comparing the efficacy of pneumatic dilation versus surgery, all symptoms were improved significantly ( p < 0.01) in both groups, except heartburn, which increased postmyotomy. Conclusions: If both procedures are available by skilled operators, pneumatic dilation and surgery are equally effective in the treatment of achalasia. 相似文献

The optimal management of reflux-induced esophageal strictures that occur after esophagomytomy for achalasia is uncertain. This paper presents our experience with the nonsurgical treatment of postesophagomyotomy strictures in achalasia patients using endoscopic dilation and gastric acid suppression. Six patients with achalasia who had undergone prior esophagomyotomy subsequently developed recurrent dysphagia and were found to have an esophageal stricture. Esophagrams typically showed a markedly dilated esophagus with a narrowed, sharply angulated gastroesophageal junction. Esophageal manometry confirmed esophageal aperistalsis and, when measured, the LES pressure was<5 mm Hg. Endoscopy showed esophageal inflammation and a fixed stricture at the gastroesophageal junction. Strictures were dilated under direct visualization using through-the-scope balloon dilators. Patients began gastric acid suppressive treatment at the same time. Five patients who remained symptomatic underwent repeat endoscopy, which demonstrated improvement in esophagitis. Dilation was then repeated with a larger balloon dilator. Over a mean follow-up period of 3.8 years, the average number of repeat dilations per patient was 3.6 (range: 0–12). All patients had symptomatic improvement and weight gain. No patient required surgery. We conclude that esophageal strictures after esophagomyotomy for achalasia can be safely treated using endoscopic dilation and gastric acid suppression, thus avoiding the need for reoperation. 相似文献

We describe a case of a long-standing, untreated achalasia with a huge sigmoid esophagus in a 58-year-old Caucasian man who declined surgery. All means of classical endoscopic approach for pneumatic dilation, including the use of an overtube, were impossible because any attempt to propel the balloon dilator made the guide wire pull back out of the stomach because of the large loops and the tortuosity of the esophagus. For this reason, we used, for the first time, a combined approach of percutaneous gastrostomy and endoscopy in order to fix the guide wire at two points, achieving a pneumatic dilation in this way. A few months later, a significant improvement in the symptoms and nutritional status of the patient were observed. 相似文献

Pneumatic balloon dilation in achalasia: a prospective comparison of balloon distention time 总被引:7,自引:0,他引:7

Objective: Duration of Inflation in pneumatic balloon dilatation as treatment of achalasia has been variable ranging from 15 s to 6 min. A 60 s duration appears to be most often used. We compared the efficacy of dilation of achalasia with either 6- or 60-s inflation duration using a Rigiflex dilator of 3.0 cm diameter.
Methods: Eighty-one consecutive patients were prospectively studied in a randomized fashion, 41 in the 60-s group (A) and 40 patients in the 6-s group (B). Mean age of group A was 43 ± 16.2 yr and of group B was 40 ± 16.4 yr. Symptoms of dysphagia, chest pain, heartburn, regurgitation, and night cough were evaluated at basal (before dilation), 1- and 6-month intervals after dilation in both groups. Barium swallow was done to assess esophageal emptying 1 wk before dilation and 5 min postdilation in both groups.
Results: Significant and sustained improvement was seen for all symptoms in both groups. In addition, the degree of improvement in symptom scores between the two groups was similar. Barium esophagram in both groups at basal and immediately postdilation showed significant improvement in barium emptying but there was no significant difference between the two groups, indicative of equal efficacy in both distention times. Two patients needed repeat dilatation in group A and one in group B, with one drop out from group A, who was lost to follow-up, and was excluded from the analysis. No perforation occurred.
Conclusion: Short duration of pneumatic balloon dilatation (6-s) is as effective as longer duration (60-s) in treatment of achalasia. 相似文献

Forceful dilation of the lower esophageal sphincter is considered primary therapy for achalasia. The Witzel pneumatic balloon dilator, unlike fluoroscopically placed dilators, is placed over a standard gastroscope allowing positioning and dilation under direct vision. We report our experience with the Witzel dilator in 45 patients with achalasia over a 5-year period. All patients had at least one major symptom score of 8 out of 10 for dysphagia and/or regurgitation before dilation. After Witzel dilation, symptomatic response was graded as excellent (score 0 to 2), good (score 3 to 5), fair (score 6 to 8), and poor (no improvement). Symptom response was assessed after 1 week, 1 month, 6 month, 1 year, and present. The mean period of follow-up was 25 months (range, 3 to 85 months). Passage of the balloon across the gastroesophageal junction was technically unsuccessful in three patients. Esophageal perforation occurred in two patients (4%) and transient chest pain greater than 2 days in three patients (7%). There was no bleeding or death. Symptomatic long-term improvement was excellent in 25 patients (63%), good in 6 patients (15%), fair in 4 patients (10%), and poor in 5 patients (12%). A repeat Witzel dilation was performed in five patients but resulted in good/excellent improvement in only one patient. We conclude that pneumatic dilation with the Witzel balloon is a safe, effective procedure for achalasia. 相似文献

Achalasia: diagnosis and management. 总被引:5,自引:0,他引:5

Achalasia is a primary esophageal motor disorder of unknown cause that produces complaints of dysphagia, regurgitation, and chest pain. The current treatments for achalasia involve the reduction of lower esophageal sphincter (LES) pressure, resulting in improved esophageal emptying. Calcium channel blockers and nitrates, once used as an initial treatment strategy for early achalasia, are now used only in patients who are not candidates for pneumatic dilation or surgery, and in patients who do not respond to botulinum toxin injections. Because of the more rigid balloons, the current pneumatic dilators are more effective than the older, more compliant balloons. The graded approach to pneumatic dilation, using the Rigiflex (Boston Scientific Corp, Boston, MA) balloons (3.0, 3.5, and 4.0 cm) is now the most commonly used nonsurgical means of treating patients with achalasia, resulting in symptom improvement in up to 90% of patients. Surgical myotomy, once plagued by high morbidity and long hospital stay, can now be performed laparoscopically, with similar efficacy to the open surgical approach (94% versus 84%, respectively), reduced morbidity, and reduced hospitalization time. Because of the advances in both balloon dilation and laparoscopic myotomy, most patients with achalasia can now choose between these two equally efficacious treatment options. Botulinum toxin injection of the LES should be reserved for patients who can not undergo balloon dilation and are not surgical candidates. 相似文献

Risk factors for immediate complications after progressive pneumatic dilation for achalasia 总被引:7,自引:0,他引:7

OBJECTIVE: The aim of this retrospective study was to determine the risk factors of early complications after progressive pneumatic dilation for achalasia. METHODS: Five hundred four dilations were performed in 237 consecutive achalasic patients between 1980 and 1994 with the same technique: low-pressure pneumatic dilation every other day with balloons of increasing diameter until success criteria were obtained (depending on manometric examination and esophageal x-ray transit performed 24 h after each dilation). Clinical, radiographical, endoscopical, and manometrical data as technical procedure characteristics for patients with perforations or other early complications were compared with those without complications. RESULTS: We observed 15 complications (6% of patients): 7 perforations (3%), 3 asymptomatic esophageal mucosal tears, 4 esophageal hematomas, and 1 fever. Perforations occurred in 6 of 7 patients during the first dilation. The mean age was 68.5 yr in the group with complications versus 56.4 yr for the remainder (p < 0.05). Two deaths occurred in patients older than 90 yr. Instability of the balloon during dilations was noted in 8 of 15 cases of complications versus 57 of 222 patients (p < 0.05). No other data differed significantly. CONCLUSIONS: This study showed a low prevalence of early complications using this progressive technique. Patients with hiatal hernia, esophageal diverticulum, or vigorous achalasia may safely undergo progressive pneumatic dilation. Only patients older than 90 yr should be referred for progressive pneumatic dilation with caution. Most of perforations arose during the first dilation, but there was no predictive pretherapeutic factor of perforation. 相似文献

Forceful balloon dilation: an outpatient procedure for achalasia 总被引:7,自引:0,他引:7

The initial treatment of choice in patients with achalasia is balloon dilation. Heretofore, this procedure was performed on an in-hospital basis resulting in high patient cost. This study evaluated the safety and efficacy of pneumatic dilation as an outpatient procedure. Sixty-one procedures were performed on 50 patients at two centers. An overall treatment success rate of 95% (47 of 50 patients) was achieved. Two patients had elective surgical treatment and a third underwent surgery for perforation secondary to dilation. A total of three patients complained of post-procedure chest pain within 4 hours and were hospitalized. Two had perforations; one required surgical repair. The third patient had resolution of symptoms. We conclude that performing balloon dilation as an outpatient procedure is safe, efficacious, and cost effective. 相似文献
