BACKGROUND: Recently, investigators have reported the use of endoscopic myotomy in the treatment of esophageal achalasia. As with the open operation, considerable disagreement exists regarding the appropriate length of the myotomy and the need for a concomitant antireflux procedure. METHODS: Patients presenting with symptomatic achalasia between 1993 and 1997 were included in this prospective study. Preoperative studies included barium upper gastrointestinal study, endoscopy, and esophageal manometry. Laparoscopic myotomy was completed in all 20 patients; 18 had concomitant Toupet fundoplication. RESULTS: Operative times ranged from 95 to 345 minutes (mean 216). Blood loss ranged from 50 to 300 cc (mean 100 cc). There were 7 minor complications (5 mucosal injuries repaired laparoscopically, 1 bile leak and 1 splenic capsular tear). Nine patients began a liquid diet on the first day postoperatively; 19 were tolerating liquids by postoperative day 3. Hospital stay ranged from 2 to 20 days (mean 5). Eighteen patients had complete relief of dysphagia, with less than one reflux episode per month. One individual continues to have mild persistent solid food dysphagia. Another patient initially did well but subsequently developed mild recurrent dysphagia and reflux. One patient required laparoscopic take-down of the wrap because of recurrent dysphagia and now has no problems swallowing, but does complain of mild reflux. Two other patients also have mild reflux, 1 of whom did not undergo fundoplication. CONCLUSIONS: Laparoscopic Heller myotomy can be performed safely with excellent results in patients with achalasia. Adding a partial fundoplication appears to help control postoperative symptoms of reflux. This procedure should be considered the procedure of choice in patients with symptomatic esophageal achalasia. 相似文献

BACKGROUND: The purpose of this study is to determine the morbidity, mortality, and short-term outcomes associated with laparoscopic paraesophageal hernia repair (LPHR). METHODS: A series of 58 consecutive LPHRs performed by the author were reviewed with an average 1-year follow-up. Morbidity and mortality rates were compared with historical series of open repairs. Anatomy and technical considerations pertinent to LPHR were reviewed. RESULTS: There were no procedure-related or perioperative deaths in this series of patients undergoing LPHR. Four major complications occurred (7%), two of which required reoperation, all in urgently repaired patients. One patient required conversion to laparotomy (1. 7%). Based on symptoms, there were no reherniations. No patients had long-term dysphagia worse than preoperatively. Preoperative symptoms of chest pain, esophageal obstruction, hemorrhage, and reflux were resolved in all patients. CONCLUSIONS: LPHR is safe, effective, and compares favorably to historical series of open paraesophageal hernia repair. 相似文献

The principal mechanism leading to gastro-oesophageal reflux is an increased frequency of transient lower oesophageal sphincter relaxations; other factors are oesophageal hypersensitivity to gastric juice, hiatus hernia, and possible duodenal reflux. Patients with classical symptoms such as heartburn and regurgitation may be treated pharmaceutically combined with life style counselling. If the symptoms have not improved after 6 to 12 weeks, endoscopical examination is performed and, if necessary, 24-hour pH monitoring, barium radiographing and manometry. In the case of atypical symptoms such as dysphagia, laryngitis, asthma and chest pain, there is more reason to pursue diagnostic testing. In patients with dysphagia endoscopy is indicated to exclude malignancy. Drug treatment can be subdivided into antacids, H2 receptor antagonists, cytoprotective agents, prokinetics and proton pump inhibitors. In general practice a step-up approach to treatment is preferable, while for specialist treatment a stepdown approach is more (cost-)effective. Drawbacks of medical treatment are considerable frequency of recurrence of oesophagitis, persistence of regurgitation in 'volume refluxers' and controversial data on the possible development of (pre)malignant lesions of oesophagus and stomach. Surgical treatment is a good alternative for patients with persistent severe regurgitation during medical therapy and for young patients who prefer surgery to lifelong medication. Patients with Barrett's oesophagus should undergo regular endoscopic biopsy surveillance. 相似文献

Various gastroenteric surgical procedures have been attempted laparoscopically. Laparoscopic esophagomyotomy (LE) with or without fundoplication, performed for achalasia, has gained popularity. In our clinic, LE (Heller's myotomy) was performed on six patients with achalasia. All patients underwent barium esophagography, endoscopy, and esophageal manometry for diagnosis. Extramucosal myotomy was started 6 cm above the cardioesophageal junction on the left anterolateral aspect of the esophagus and continued 1 cm below this area. Endoscopic control of the distal esophageal mucosa and the stomach was carried out under direct laparoscopic visualization following the completion of myotomy during the operation. LE was completed without complication in five patients. In one patient (16%), mucosal perforation occurred after myotomy during endoscopic control and was repaired with endostitches. There were no postoperative complications. The average hospital stay was 3 days. Three of the six patients agreed to 24-h pH monitoring, the results of which showed no evidence of reflux. All patients were completely symptom free in the postoperative period. The average preoperative lower esophageal sphincter pressure was 44 mm Hg, whereas in the early postoperative period and 6 months later, it was 11 mm Hg. There was no dysphagia or reflux esophagitis during the follow-up period (range 12 to 24 months). LE is associated with low morbidity and a high success rate, comparable with an open procedure, and can be done without an antireflux procedure. 相似文献

Oropharyngeal dysphagia in adults is secondary to either a structural lesion or neuromuscular disorder of the upper esophageal sphincter. In cricopharyngeal achalasia (incomplete relaxation of the upper esophageal sphincter), the etiology is usually either related to neck surgery or other neuromuscular disorders. We report on a rare case of neuromuscular oropharyngeal dysphagia secondary to bone metastases to the base of the skull. The patient is an 81-year old man with prostate cancer with metastases to the sacrum. A gastroscopy was attempted to discern the etiology of his dysphagia, but the endoscope could not be advanced. A barium swollow showed cricopharyngeal achalasia, and an magnetic resonance image of the brain demonstrated bone destruction to the floor of the left posterior fossa in the region of the jugular foramen and foramen magnum. The bone destruction caused disruption of the glosso-pharyngeal and vagus nerves. Selective radiotherapy resulted in rapid improvement in his symptoms. The primary treatment of cricopharyngeal achalasia is to correct the underlying process, if possible. This case illustrates an unusual presentation of secondary cricopharyngeal achalasia caused by cranial nerve involvement secondary to bone metastases. 相似文献

Achalasia is a functional disorder of the alimentary tract due to decreased or absent peristalsis of the esophageal body and obstructive outlet of the esophagus. Surgical treatment, eg. esophagomyotomy of the lower esophageal sphincter (LES), was one choice for resolving the problem and its effect was affirmative from reviews of many internationally authorized articles. However, few reports have ever questioned the long-term effects of it. From January 1968 to May 1996, 159 esophageal achalasic patients, 90 males and 69 females, were admitted due to dysphagia or food regurgitation. One hundred and forty-five patients had received 158 operations related to this benign motor disorder. The majority of patients received either modified Heller esophagomyotomy (M) or M plus modified Belsy Mark IV antireflux procedure (M+W) for primary treatment of their esophageal disorder, while conditional selection with addition of esophageal resection as advanced procedures for failure of primary surgery. We retrospectively studied these patients, collected their preoperative and postoperative clinical results, analyzed the causes of recurrent symptoms, compared the long-term results in different surgical procedures and searched for the pathogenesis of their failure. The results disclosed that the overall success rate for both methods was 73.1% with 85.7% for patients receiving M+W (56) and 64.9% of M (77) only. Through long-term follow-up, we had an improvement rate of 97.4% at an early stage and 53.3% for M at a late stage and 98.4% and 55.6% for M+W, respectively. The postoperative natural course of achalasic patients could be seen and progressive deterioration of the operated patients with time was noted. Several factors might contribute to the causes of unsuccessful surgery. We summarized them as incomplete myotomy, fused or healed myotomy, gastroesophageal reflux (GER), mucosal hernia and co-combined antireflux procedure by hypercalibrated or floppy wrapping. Esophagomyotomy or myotomy plus antireflux procedure for the esophagus could be concluded to rather effective in the long-term but palliative treatments for achalasia chronic deterioration of the results could be found for both of them. Defective myotomy and GER may be the major causes for their failure. The choice of types of surgery between M and M+W was not the cause of the unsuccessful results whereas the operative strategy and procedures would have a certain significance on the long-term effect. 相似文献

Impaired esophageal body motility is a complication of chronic gastroesophageal reflux disease (GERD). In patients with this disease, a 360-degree fundoplication may result in severe postoperative dysphagia. Forty-six patients with GERD who had a weak lower esophageal sphincter pressure and a positive acid reflux score associated with impaired esophageal body peristalsis in the distal esophagus (amplitude <30 mm Hg and >10% simultaneous or interrupted waves) were selected to undergo laparoscopic Toupet fundoplication. They were compared with 16 similar patients with poor esophageal body function who underwent Nissen fundoplication. The patients who underwent Toupet fundoplication had less dysphagia than those who had the Nissen procedure (9% vs.44%; P=0.0041). Twenty-four-hour ambulatory pH monitoring and esophageal manometry were repeated in 31 Toupet patients 6 months after surgery. Percentage of time of esophageal exposure to pH <4.0, DeMeester reflux score, lower esophageal pressure, intra-abdominal length, vector volume, and distal esophageal amplitude all improved significantly after surgery. Ninety-one percent of patients were free of reflux symptoms. The laparoscopic Toupet fundoplication provides an effective antireflux barrier according to manometric, pH, and symptom criteria. It avoids potential postoperative dysphagia in patients with weak esophageal peristalsis and results in improved esophageal body function 6 months after surgery. 相似文献

OBJECTIVE: To examine the factors affecting outcome in patients with advanced gastroesophageal reflux disease. DESIGN: Retrospective analysis. SETTING: University tertiary referral center. PATIENTS: Thirty-seven patients with advanced gastroesophageal reflux disease and no previous antireflux surgery. INTERVENTIONS: Thirty patients underwent Collis gastroplasty for esophageal lengthening and Belsey partial fundoplication. Seven patients with esophageal stricture and global loss of esophageal body motility who underwent primary esophagectomy and reconstruction were used as a comparison group. OUTCOME MEASURES: Symptomatic outcome in all 37 patients was assessed by questionnaire at a median of 25 months (range, 5-156 months) after surgery. In a subset of 11 patients undergoing the Collis-Belsey procedure, outcome was measured using 24-hour pH and results of motility studies. RESULTS: The Collis-Belsey procedure was successful in relieving symptoms of gastroesophageal reflux in 21 (70%) of the 30 patients. The outcome was excellent or good in 16 (89%) of 18 patients who presented with symptoms other than dysphagia, but only in 5 (42%) of 12 patients with dysphagia (P = .01). The outcome was particularly poor if dysphagia was associated with a previously dilated esophageal stricture. Persistent or induced dysphagia was the reason for failure in all but 1 patient. Results of 24-hour esophageal pH studies were returned to normal in 8 (73%) of 11 patients undergoing postoperative evaluation. Contraction amplitudes in the distal esophagus and the prevalence of simultaneous contractions in these segments did not change after the operation. All 7 patients who underwent primary esophagectomy were classified as having an excellent or good outcome and were relieved of their reflux symptoms, including dysphagia. Six of these could eat 3 meals per day and enjoyed an unrestricted diet. CONCLUSIONS: The outcome of the Collis-Belsey procedure in patients with advanced gastroesophageal reflux disease without dysphagia is excellent. It is less so in patients with dysphagia as a preoperative symptom. Esophagectomy can provide a good outcome in patients who have a combination of dysphagia stricture and a profound loss of esophageal motility. 相似文献

The Nissen fundoplication is the most common operative approach to the correction of gastroesophageal reflux disease (GERD) in the United States. This report describes our success in performing this anti-reflux procedure laparoscopically in 28 patients with symptomatic GERD refractory to conventional medical therapy. Our laparoscopic technique does not differ significantly from the traditional, open Nissen fundoplication. After surgery, all patients reported symptomatic relief, and none required medication for the control of reflux symptoms. Oral feedings were begun on the first postoperative day, and patients were typically discharged on the second day after surgery. All but two patients resumed normal eating within an average of 26 days. Two patients experienced longer term postoperative dysphagia, including one who had undergone a highly selective vagotomy concurrent with the antireflux surgery. 相似文献

Two cases of recurrent and persistent respiratory symptoms after primary repair of esophageal atresia and tracheoesophageal fistula are described. The diagnostic workup included barium swallow examination, radionuclide study for gastroesophageal reflux, and bronchoscopy. The tracheal diverticulum was detected on bronchoscopy. Treatment consisted of endoscopic cauterization of the mucosa of the diverticulum and its orifice using electrocoagulation in case 1 and the Nd:YAG laser in case 2. Electrocoagulation produced tracheal edema, which caused severe respiratory distress necessitating temporary tracheostomy. Cauterization with the Nd:YAG laser was safe, effective, and uncomplicated. 相似文献

Lansoprazole is a proton pump inhibitor that reduces gastric acid secretion. It has proved effective in combination regimens for the eradication of Helicobacter pylori and as monotherapy to heal and relieve symptoms of gastric or duodenal ulcers and gastro-oesophageal reflux. After initial healing, it may be used to prevent recurrence of oesophageal erosions or peptic ulcers in patients in whom H. pylori is not the major cause of ulceration and to reduce basal acid output in patients with Zollinger-Ellison syndrome. Usual dosages are 15 to 60 mg/day, although dosages of < or = 180 mg/day have been used in patients with hypersecretory states. In patients with duodenal or gastric ulcer, short term lansoprazole monotherapy was similar to omeprazole and superior to histamine H2 receptor antagonists in achieving healing rates > 90%. Lansoprazole was as effective a component of H. pylori eradication regimens as omeprazole, tripotassium dicitrato bismuthate (colloidal bismuth subcitrate) or ranitidine. Lansoprazole was superior to ranitidine in symptom relief and healing of gastro-oesophageal reflux disease and tended to relieve symptoms more rapidly than omeprazole, although initial healing was similar. As maintenance treatment, lansoprazole was similar to omeprazole and superior to ranitidine in relieving symptoms and preventing relapse. Lansoprazole was also superior to ranitidine in healing and relieving symptoms of oesophageal erosions associated with Barrett's oesophagus; healing was maintained for a mean of 2.9 years in > or = 70% of patients. Lansoprazole was also superior to ranitidine in prophylaxis of redilatation of oesophageal strictures. After > or = 4 years of use in patients with Zollinger-Ellison syndrome, lansoprazole 60 to 180 mg/day effectively controlled basal acid output. Dosages may be reduced in some patients once healing and symptom relief has been achieved. Preliminary studies of lansoprazole in patients at risk of aspiration pneumonia or stress ulcers show promise. Although studies show lansoprazole is potentially effective in treating gastrointestinal bleeding, future studies should assess patients' H. pylori status. Lansoprazole has been well tolerated in clinical trials, with headache, diarrhoea, dizziness and nausea appearing to be the most common adverse effects. Tolerability of lansoprazole does not deteriorate with age and the drug is well tolerated in long term use (< or = 4 years) in patients with Zollinger-Ellison syndrome or reflux disease. Thus, lansoprazole is an important alternative to omeprazole and H2 receptor antagonists in acid-related disorders. In addition to its efficacy in healing or maintenance treatment, it may provide more effective symptom relief than other comparator agents. 相似文献

Results of an ongoing clinical study treating achalasia patients with laparoscopic Heller myotomy and Dor anterior fundoplication are presented. 18 patients underwent surgery between August 1991 and July 1995. Completeness of myotomies and calibration of fundoplications were measured using intraoperative manometry. Only one intraoperative complication, a perforation of the mucosa sutured laparoscopically, was encountered. There were no surgical mortalities nor postoperative morbidities. Mean hospital stay was 3.4 days. Complete relief of dysphagia and modifications of radiological and manometric patterns were achieved in all patients. All patients remain asymptomatic at 2 to 48 months from surgery. These results compare favourably with those of traditional surgery and of pneumatic dilatation. 相似文献

Hoarseness, asthma, and bronchitis are common but sometimes obscure manifestations of gastroesophageal reflux, the etiology of when respiratory symptoms predominate. In 300 consecutive patients who underwent surgical correction for gastroesophageal reflux, 129 (43%) had major respiratory complaints. Group 1 patients (82, 64%) were those referred for respiratory problems alone. In Group 2 (patients referred because of peptic complaints), 47 had associated respiratory problems in various combinations, including an additional 10 patients who had bronchiectasis. Treatment with appropriate surgical resection, in addition to antireflux procedures, was carried out in these people. Noticeable relief of respiratory symptoms was obtained in 96 (74%) of the 129 patients; 30 were improved and 2 were unchanged. Recurrent hiatus hernia or esophagitis was documented in 21 (7%) of the 300 patients. 相似文献

BACKGROUND: Ventricular septal myotomy/myectomy (Morrow procedure) is the standard surgical option for severely symptomatic patients with hypertrophic cardiomyopathy (HCM) and marked basal obstruction to left ventricular outflow due to mitral valve systolic anterior motion. In some patients, however, congenital malformations of the mitral apparatus may be responsible for outflow obstruction; the failure to recognize this morphology before operation could have adverse consequences. METHODS AND RESULTS: We recently evaluated 2 patients with obstructive HCM operated on at Mayo Medical Center in 1997 who demonstrated direct anomalous papillary muscle insertion into the anterior mitral leaflet, producing muscular midcavity obstruction. This anomaly is potentially identifiable with echocardiography by exaggerated anterior displacement of hypertrophied papillary muscles within the left ventricular cavity and the direct continuity between papillary muscle and anterior leaflet associated with a rigid motion pattern of the mitral apparatus. Echocardiographic diagnosis, however, was confused in both patients by the association of systolic anterior motion of the mitral valve, probably produced by freely mobile margins of the mitral leaflet unencumbered by papillary muscle insertion, and in 1 patient probably representing a second and more basal level of obstruction. Because outflow tract morphology was judged unsuitable for conventional myotomy/myectomy, a novel surgical strategy was designed to remove the outflow gradient in which an extensive myectomy trough (wider at its apical than basal extent) was created within the ventricular septum to papillary muscle level; also, in 1 patient, attachment of anterolateral papillary muscle with the lateral free wall was partially severed to increase mobility of the mitral apparatus. After surgery, both patients reported substantial relief of symptoms and improved exercise tolerance and also showed reduced or abolished basal outflow obstruction. CONCLUSIONS: In HCM, outflow obstruction due to anomalous papillary muscle insertion directly into anterior mitral leaflet is challenging to identify but should always be contemplated before operative intervention. This important (but often unsuspected) congenital malformation may require alternative surgical strategies to standard myotomy/myectomy, similar to those described here. 相似文献

Dysphagia, or disordered swallowing, can be demonstrated at any time over the course of many myopathies. Ability to swallow may be impaired because of weakness, inflammation, or dysfunction of the oropharyngeal, laryngeal, and esophageal musculature. Dysphagia may occur during the progression of disease regardless of whether the patient is properly treated. The presentation of signs of dysphagia can vary among patients because of differing patterns of weakness or incoordination of the facial muscles, lips, tongue, palate, pharyngeal constrictors, or smooth and striated muscles of the esophagus. Although the literature has focused on problems in the esophagus, scant attention has been paid to the oropharynx, which is often equally affected. Studies suggest that surgical myotomy and botulinum toxin injection may provide benefits for some patients with esophageal dysfunction. Although the condition is pervasive, there is little information on the incidence of dysphagia in muscular disorders. Because a major complication of dysphagia is aspiration, any sign of swallowing impairment demands medical attention and treatment. 相似文献

Most patients with carcinoma of the esophagus have advanced disease at presentation. Since cure is usually not possible, the goal of treatment is the palliation of dysphagia. Palliative modalities include bougies, balloons, stents, tumor probe, laser, surgery, chemotherapy, and radiation. In recent years, combined chemotherapy and radiation has shown promising results. However, the relief of dysphagia is slow and frequently incomplete. We compared the effectiveness of dilatation alone versus dilatation plus Nd-YAG laser therapy for the relief of dysphagia while assessing the role of chemotherapy and radiation as an adjunct to surgery. Fifteen patients with squamous cell carcinoma of esophagus who were deemed fit for intensive chemotherapy and radiation were randomized to receive either dilatation alone (N = 7) or dilatation plus laser (N = 8); the end-point for initial success was the passage of a 45 French Savary dilator, and the relief of dysphagia. At entry, 13 of these 15 patients were judged potentially resectable. However, after chemotherapy and radiation, only 3 of 13 (20%) patients could be offered surgery; the remainder were considered too poor a surgical risk. Follow-up was for 30 months, or until death. Further dilatations were performed as needed for relief of dysphagia. No difference was observed between the laser plus dilatation and the dilatation alone group with respect to the degree of dysphagia, weight record, quality of life index (Karnofsky score), or mortality rate. Our results indicate that in patients undergoing chemotherapy and radiation for esophageal carcinoma, dilatation alone provides adequate palliation of dysphagia, and in these patients, chemotherapy and radiation is a poor adjunct to surgical treatment. 相似文献

OBJECTIVE: To study extensively the therapeutic approach of gastroesophageal reflux disease in intellectually disabled children. DESIGN: We studied the effect of omeprazole sodium on healing and symptom relief in 52 institutionalized intellectually disabled children (male-female, 21:31; mean age, 15.4 years; range, 4-19 years). INTERVENTION: Endoscopically proven esophagitis (grades I-IV, Savary-Miller classification) was treated with omeprazole sodium, 40 mg/d (20 mg/d for children weighing <20 kg) as healing dose for 3 months, and 20 mg/d (10 mg/d for children weighing <20 kg) as maintenance dose for another 3 months. After 3 and 6 months, results of treatment were evaluated using symptom scoring and/or endoscopy. For patients with relapse, the dose was increased. RESULTS: At first endoscopy, 19 patients (36%) of 52 showed grade I esophagitis; 20 (38%), grade II; 6 (12%), grade III; and 7 (13%), grade IV. In 44 (86%) of 51 patients, treatment was effective in healing esophagitis and keeping patients in remission, independent of the severity of esophagitis. In 7 patients (14%), a symptomatic relapse was observed after decreasing the dose. However, these patients became symptom free again after increasing the dose and showed healing on endoscopy at the end of the study. One child did not finish the study for reasons not related to therapy. Marked improvement of persistent vomiting, regurgitation, food refusal, iron deficiency anemia, and signs of depression was seen at the end. CONCLUSIONS: Omeprazole is highly effective for all grades of esophagitis in intellectually disabled children, without adverse effects. The dose needed to maintain the remission can be titrated according to the reflux symptoms. One disadvantage of medical therapy is that it is open ended, in contrast to operation, but surgery in this population has high mortality and complication rates. 相似文献

Gastroesophageal reflux (GER) can develop in patients with esophageal achalasia either before treatment or following pneumatic dilatation or Heller myotomy. In this study we assessed the value of pre- and postoperative pH monitoring in identifying GER in patients with esophageal achalasia. Ambulatory pH monitoring was performed preoperatively in 40 patients with achalasia (18 untreated patients and 22 patients after pneumatic dilatation), 27 (68%) of whom complained of heartburn in addition to dysphagia (group A), and postoperatively in 18 of 51 patients who underwent a thoracoscopic (n=30) or laparoscopic (n=21) Heller myotomy (group B). The DeMeester reflux score was abnormal in 14 patients in group A, 13 of whom had been treated previously by pneumatic dilatation. Two types of pH tracings were seen: (1) GER in eight patients (7 of whom had undergone dilatation) and (2) pseudo-GER in six patients (all 6 of whom had undergone dilatation). Therefore 7 (32%) of 22 patients had abnormal GER after pneumatic dilatation. Postoperatively (group B) seven patients had abnormal GER (6 after thoracoscopic and 1 after laparoscopic myotomy). Six of the seven patients were asymptomatic. These findings show that (1) approximately one third of patients treated by pneumatic dilatation had GER; (2) symptoms were an unreliable index of the presence of abnormal GER, so pH monitoring must be performed in order to make this diagnosis; and (3) the preoperative detection of GER in patients with achalasia is important because it influences the choice of operation. 相似文献

Manometric, pH-metric, radiological and histological examinations were performed in 15 of 18 consecutive patients with gastro-esophageal reflux before and after fundoplication. In 13 of these 15 patients, reflux symptoms largely or completely disappeared after the operation. In the successfully operated patients, the reflux provocation test markedly improved but lower esophageal sphincter pressure did not rise. Six successfully operated patients in whom hiatus hernia was present after the operation and 7 patients without hernia had similar esophageal function tests. Therefore, success of surgery does not depend on resting pressure and position of the lower esophageal sphincter. 相似文献

In four children, barium was refluxed into the nasopharynx, eustachian tubes, and middle ears during routine upper gastrointestinal series. Three children had gastroesophageal reflux and one had incoordination of swallowing. The possible significance of such reflux with regard to middle ear disease is not known. 相似文献
