Severe complications following a "barium swallow" investigation for dysphagia

OBJECTIVE: To highlight the risks of investigation of patients with swallowing disorders by "barium swallow", when the disorders may arise from dysfunction of the upper swallowing tract. CLINICAL FEATURES: An 81-year-old Italian woman presented to her local doctor with a history of dysphagia of five days' duration. A barium swallow resulted in aspiration of a large amount of barium into the right main bronchus, causing severe problems. After a period of intensive respiratory care including intubation and continuous positive airway pressure, she recovered sufficiently to be referred to a rehabilitation unit. She had mild hemiplegia but severe dysphagia, secondary to a brain stem infarct. INTERVENTION AND OUTCOME: Persisting severe dysphagia was confirmed, with extreme risk of aspiration. The patient underwent percutaneous endoscopic gastrostomy and was discharged to live independently, but requiring long-term gastrostomy feeding. CONCLUSION: When a patient presents with dysphagia, great care should be taken to exclude upper tract dysfunction with its attendant risk of aspiration, generally by referral to a centre or consultant with expertise in this area, before ordering or carrying out investigations appropriate to disorders of the lower tract.     

Swallowing changes in cerebrovascular accidents: incidence, natural history, and repercussions on the nutritional status, morbidity, and mortality

OBJECTIVE: To determine the frequency of dysphagia in CVA, its natural history and value as a risk factor of respiratory infection, malnutrition and death. PATIENTS AND METHODS: A prospective study was made of 187 consecutive patients with cerebrovascular accidents (CVA). A standardized test for dysphagia was done during the first two days of the illness and repeated three days a week. The levels of urea, total proteins and albumin were determined on admission and on discharge. The patients were questioned by phone after 6 months. RESULTS: There was dysphagia of liquids in 36.4% of the patients. The incidence of dysphagia for semisolids was of the same frequency but more severe. Coma was the cause of inability to swallow in 25.7% of the patients. During their stay in hospital one third of the patients with dysphagia died, one third became normal and one third still had dysphagia when they were discharged. After one week, one, three and six months respectively, the cure rate for dysphagia was 29.4%, 4.1%, 55.9% and 55.9%, and survival 83.8%, 67.6%, 61.8% and 60.3%. Thus after 6 months only 3 patients (4.4%) were alive and dysphagic. Half of the 'cures' occurred in the first week, and none occurred after more than 77 days. As compared to the non-dysphagic patients, the dysphagic patients had 10 times more risk of respiratory infection, 18 times higher risk of death, greater loss of albumin and less loss of urea. CONCLUSIONS: There is a high prevalence of dysphagia in CVA and although functional prognosis is not unfavorable, respiratory infections, malnutrition and death are frequent.     

Solid bolus swallowing in the radiologic evaluation of dysphagia

Patients with dysphagia, heartburn and chest pain are regularly referred for radiologic evaluation of swallowing. The liquid barium swallow has been of great value for the biphasic evaluation of the pharynx and esophagus. Though many patients complain of dysphagia specifically for solids, solid bolus swallow is usually not part of the evaluation. For the present study we therefore included the use of a solid bolus with a diameter of 13 mm and interviewed the patients carefully for any symptoms during this tablet swallow. Of 200 patients examined, the tablet passed through the esophagus without delay in 102. In the 98 patients with delayed passage, the solid bolus arrest occurred in the pharynx in 5 and in the esophagus in 93. Arrest in the esophagus was due to esophageal dysmotility in 48 patients. Twenty of these were symptomatic during the tablet swallow. A narrowing was the cause in 45, of whom 9 had symptoms. In 18 patients (9%) the solid bolus added key information to the radiologic evaluation. We therefore recommend that the solid bolus is included in the routine radiologic work-up of patients with dysphagia. Careful attention to symptoms during the tablet swallow is important.     

Arthroscopic removal of an osteoid osteoma at the talar neck

PURPOSE: This study used simultaneous videomanometry to measure pressure characteristics in a group of patients with evidence of laryngeal and/or tracheal barium penetration, and to compare the results to those of one group of healthy volunteers and one group of patients with dysphagia but a normal barium swallow. MATERIAL AND METHODS: Videomanometry during barium swallowing was performed in 25 patients who showed penetration of barium into the laryngeal vestibule. Manometric abnormalities were determined by comparing these mean values with those of 25 healthy volunteers, and the frequency of manometric abnormalities was compared to that of 19 patients presenting with oropharyngeal dysphagia with a normal barium swallow. RESULTS: The frequency of abnormalities for four parameters (pharyngo-esophageal segment (PES) resting pressure, PES relaxation duration, pharyngeal peak pressure, pharyngeal contraction duration) differed significantly between the patients with penetration and those with normal barium studies. There was, however, no association between manometric abnormalities and the degree of barium penetration. CONCLUSION: The differences in manometric abnormalities between patients with laryngeal penetration and patients with normal barium swallows may be useful in identifying the mechanisms of laryngeal penetration.     

Quality of life after knee arthroplasty. A randomized study of 3 designs in 42 patients, compared after 4 years

BACKGROUND: An initial multicenter study using a 21 mm flanged esophageal Z stent demonstrated excellent palliation but an 11% immediate complication rate at placement and a 27% migration rate at 1 month. This North American multicenter trial prospectively studied a 25 mm flanged Z stent to define its palliative ability and whether the increased diameter affected placement or migration problems. METHODS: Fifty patients who had esophageal Z stents at seven university or regional referral hospitals were prospectively studied. Indications for prosthesis placement, previous therapy, patient demographics, incidence of concomitant tracheoesophageal fistula, and degree of dysphagia were defined, as were procedural and subsequent stent-related problems, survival times, the ability to occlude a tracheoesophageal fistula, and subsequent degree of dysphagia. RESULTS: Twenty-four patients had infiltrating malignancy (16 exophytic and 10 extrinsic), 9 of whom had concomitant tracheoesophageal fistulas. Ten patients (20%) had misplaced stents requiring retrieval and replacement, 12 patients (24%) had subsequent stent-related problems including exsanguination (2), aspiration (3), tumor overgrowth (3), and postplacement migration (4) (8%). There was statistically significant improvement in prestent versus poststent dysphagia and two thirds of patients had complete occlusion of their tracheoesophageal fistula. CONCLUSIONS: Redesign of the esophageal Z stent has decreased the migration rate without increasing placement or subsequent erosion problems. Its efficacy appears comparable to the currently marketed Z stent for the palliation of malignant dysphagia and occlusion of tracheoesophageal fistula.     

Schatzki ring in children and young adults: clinical and radiologic findings

BACKGROUND: The Schatzki ring is a well-known clinical and radiologic entity in adults, but is thought to be rare in childhood. Objective. To review the clinical presentations and radiologic findings of children and young adults with Schatzki rings. MATERIALS AND METHODS: A retrospective review of all barium swallow examinations done between 1990 and 1996 revealed 20 patients with Schatzki rings. RESULTS: The most frequent presenting symptoms of these patients were progressive dysphagia with solid food and acute food impaction. Radiographic findings of Schatzki rings were typical in all cases. Twelve patients had endoscopy and all had evidence of esophagitis. CONCLUSION: Schatzki rings are not rare in childhood. The patients are symptomatic, presenting with either progressive dysphagia with solids or acute food impaction. A thorough evaluation of the distal esophagus should be performed in patients with a suggestive clinical history.     

Endoscopic treatment of malignant dysphagia

Palliative endoscopic treatment of dysphagia in patients with inoperable oesophageal cancer includes: dilation, Nd:YAG laser photocoagulation and intubation, used alone or in combination. Such procedures are usually performed on an outpatient basis and are associated with a low rate of morbidity and mortality. From 1978 to 1988, 476 patients (401 males, 75 females) were treated at the Endoscopy division of the National Cancer Institute of Milan for inoperable primary or recurrent malignancies of the oesophagus or cardia or for extra-oesophageal neoplasms causing dysphagia. Dilation was used in 172 cases, Nd:YAG laser photocoagulation in 90, prosthesis insertion in 72, dilation and laser in 97, and prosthesis and laser in 45. Functional improvement was reported in 75% of patients after dilation, in 89% after laser treatment, in 80% after intubation, in 80% after dilation and photocoagulation, and in 89% after laser and intubation. The median duration of dysphagia-free interval was 4 weeks in dilated patients, 6-8 weeks in photocoagulated patients and 20 weeks intubate patients. Overall median survival was 6.2 months. The complication rate was: 1.4% in dilation treatment, 1.4% in laser photocoagulation, and 8.8% in prosthesis intubation. Mortality related to endoscopic treatment was 2.1% (10/476 patients). Relief of dysphagia is one of the most important goals of palliative treatment in patients with inoperable oesophageal neoplasms. Moreover, endoscopic palliation improves the quality of life in the patients, with a low complication rate.     

Telemedicine in Australia. Recent developments

To assess the frequency and natural history of swallowing problems following an acute stroke, 121 consecutive patients admitted within 24 hours of the onset of their stroke were studied prospectively. The ability to swallow was assessed repeatedly by a physician, a speech and language therapist, and by videofluoroscopy. Clinically 51% (61/121) of patients were assessed as being at risk of aspiration on admission. Many swallowing problems resolved over the first 7 days, through 28/110 (27%) were still considered at risk by the physician. Over a 6-month period, most problems had resolved, but some patients had persistent difficulties (6, 8%), and a few (2, 3% at 6 months) had developed swallowing problems. Ninety-five patients underwent videofluoroscopic examination within a median time of 2 days; 21 (22%) were aspirating. At 1 month a repeat examination showed that 12 (15%) were aspirating. Only 4 of these were persistent; the remaining 8 had not been previously identified. This study has confirmed that swallowing problems following acute stroke are common, and it has been documented that the dysphagia may persist, recur in some patients, or develop in others later in the history of their stroke.     

Treatment of progressive supranuclear palsy with amitriptyline: therapeutic and toxic effects

BACKGROUND: Progressive supranuclear palsy (PSP) is a parkinsonian-like disorder characterized by postural instability, rigidity, bradykinesia, supranuclear ocular palsy, dysarthria, dysphagia, and dementia. There is no satisfactory treatment. Two patients with advanced (PSP) reported here had clinically meaningful improvement in motor function on low dose amitriptyline (AMI) but developed cognitive and behavioral disturbances at higher doses. CASE REPORTS: During 11 weeks of upward dose titration, a 65-year-old man was partially relieved of severe bradykinesia, dysarthria, and dysphagia at an optimal dose of 40 mg bid (plasma AMI 39 ng/mL) such that he could feed himself, swallow easily, and transfer from wheelchair to toilet. Nocturnal confusion and urinary incontinence appeared at 70 mg bid, then resolved at 40 mg bid. Benefits were sustained during the next 14 months. A 77-year-old man had substantial relief of severe rigidity, bradykinesia, poor balance, and blepharospasm at 10 mg bid, such that he could feed himself and walk independently. At 40 mg bid (plasma AMI 62 ng/mL) 3 weeks later, he became aggressive, irritable, and increasingly confused. He reverted to his untreated state with drug withdrawal, then improved when AMI was reintroduced at 10 mg bid (plasma AMI 17 ng/mL). CONCLUSION: Low dose AMI may improve severe motor dysfunction in PSP significantly. Dosing must be individualized for optimal response and minimal toxicity.     

Evaluation of an immunohistochemical test with polyclonal antibodies raised against mycobacteria used in formalin-fixed tissue compared with mycobacterial specific culture

OBJECTIVES: In neurogenic dysphagia a good cough is important for airway protection. If triggering of cough, or its effectiveness, is impaired this might result in an increased aspiration risk. Capsaicin, an agent which induces cough through sensory nerve stimulation, was used to test cough sensitivity in groups of patients with and without neurogenic dysphagia. METHODS: On the basis of swallowing speed (ml/s) in a validated water test 28 alert neurological inpatients (16 women, aged 22-71 years) were classified into 13 with abnormal and 15 with normal swallowing (median swallowing speed 23% and 99%, median volume/swallow 43% and 106% of that predicted for age and sex respectively: p<0.001). Capsaicin nebulised on air in saline was inhaled via a low resistance valve using a mouthpiece and noseclip. Up to seven incremental concentrations of capsaicin ranging from 0.07-20.0 x 10(-4) mol/l were each inhaled for up to a minute. A pneumotachograph connected to the expiratory limb gave a paper recording of expiratory air flow. Coughs were recorded as high flow expirations of short duration. Capsaicin concentrations at first cough (threshold) were recorded; concentrations at frequencies of 10 and 20 coughs/minute were interpolated from the dose-response curve. RESULTS: Cough threshold tended to be lower in those with abnormal swallowing (non-significant): the (log) concentration of capsaicin producing 10 or 20 coughs/ minute also tended to be lower (p=0.12 and 0.07 respectively) in those with abnormal swallowing. CONCLUSION: Contrary to expectation, these results suggest that cough responsiveness is enhanced in alert patients with neurogenic dysphagia even after allowing for diagnostic category, the possible presence of a bulbar upper motor neuron lesion, or voluntary respiratory capacity. It is concluded that these patients with neurogenic dysphagia do not have a reduced sensitivity of cough triggering.     

Clinical and electrophysiological evaluation of dysphagia in myasthenia gravis

OBJECTIVE: To evaluate dysphagia at the oropharyngeal stage of swallowing and to determine the pathophysiological mechanisms of dysphagia in patients with myasthenia gravis. METHODS: Fifteen patients with myasthenia gravis with dysphagia and 10 patients without dysphagia were investigated by a combined electrophysiological and mechanical method described previously. Laryngeal movements were detected by a piezoelectric transducer and the related submental EMG (SM-EMG) and sometimes the EMG of cricopharyngeal muscle of the upper esophageal sphincter (CP-EMG) were recorded during dry or wet swallowing. The results of these electrophysiological variables were compared with those of normal age matched control subjects. RESULTS: In patients with myasthenia gravis with dysphagia, it was found that the time necessary for the larynx to remain in its superior position during swallowing and swallowing variability in successive swallows increased significantly compared with normal subjects and with patients with myasthenia gravis without dysphagia. The total duration of SM-EMG activity was also prolonged in both groups but more severely in the dysphagic patients. Electromyographic activity of the CP sphincter was found to be normal in the dysphagic patients investigated. All the patients with myasthenia gravis with dysphagia had pathological dysphagia limits (<20 ml water) whereas other patients except two, were within normal limits. CONCLUSIONS: Because the electrophysiological variables related to oropharyngeal swallowing were prolonged even in patients with myasthenia gravis without dysphagia, it is concluded that the submental and laryngeal elevators are involved subclinically in myasthenia gravis and, because of compensating mechanisms, the patient may not be dysphagic. As the CP-EMG behaviour was found to be normal, a coordination disorder between normal CP sphincter muscle and the affected striated muscles of the laryngeal elevators may be one of the reasons for dysphagia in myasthenia gravis. This method also made it possible to investigate the myasthenic involvement in the laryngeal elevators that cannot be evaluated by other electrophysiological methods in myasthenia gravis.     

Improvement of swallowing ability in advanced oesophageal cancer

Without different types of palliation the patients with inoperable oesophageal cancer have a poor quality of life, rapid weight loss which leads to death. The aim of palliation is the complete relief of dysphagia. Our modified procedure is a simplified way of a well known method described by Tytgat in 1986. The prosthesis is positioned under continuous visual control using only local anaesthesia. This method is safe and not expensive. During the last three years 73 consecutive patients were treated with palliative fiberoscopic intubation with Tygon prosthesis. 46 patients had esophageal carcinoma, 19 had gastric, 8 had pulmonary carcinoma obstructing the gullet. Among them 11 patients had bronchoesophageal fistula. The early complications were perforations (7) bleeding (2), and later complications: food impaction (5) tumor overgrowth (5) and tube migration (2). The mortality was 2%. All patients have received antibiotic prevention. Although the improvement of life quality is more important than extension of life, for many patients survival will be prolonged due to improved nutrition as a result of treatment. This study summaries our experience with this technique and analyzes the problems and complications encountered in our patients.     

Motility disorders of the esophagus: diagnosis with barium-rice administration

PURPOSE: To evaluate the role of barium-rice administration for a standardized diagnosis of dysphagia and esophageal motility disorders. MATERIALS AND METHODS: Sixty healthy volunteers and 218 patients with various esophageal disorders (achalasia, scleroderma and other connective tissue diseases, neurologic diseases, esophagitis and others) were examined both by a conventional barium study and by a barium-rice study. The barium-rice meal consisted of barium sulfate and boiled rice, mixed half and half. The time required for esophageal clearance of one sip was measured. RESULTS: Normal esophageal transit time in healthy controls was between 5 and 15 s for both methods. In patients, the conventional barium study revealed a prolonged transit time in only 16.5% (36 of the 218 cases). The barium-rice study was abnormal in 51.8% (113 of 218 cases), independent of the underlying disease. The barium-rice study was pathological in 77 of those 182 patients (42.3%) who had normal barium transit time. In 24 patients the radiologic results was confirmed by endoscopy and manometric measurements. CONCLUSIONS: Esophageal motility abnormalities are detected by a barium-rice study with a high sensitivity. With this simple and low-cost method, quantitative and reproducible results can be obtained. Barium-rice administration is a suitable tool for screening and follow-up of patients with dysphagia and esophageal motility disorders.     

Endoscopic treatment of Zenker's diverticulum using CO2 laser. 17 cases

OBJECTIVES: Various treatment regimens have been used for the management of Zenker's diverticulum. These include surgery (transcervical diverticulectomy, myotomy) and endoscopic treatment with rigid instruments or flexible endoscope. The aim of this study is to report the results of the treatment of Zenker's diverticulum with rigid endoscope applied CO2 laser and to compare them with other types of treatment. PATIENTS AND METHODS: Between May 1991 and November 1996, 17 patients (8 males, 9 females) with symptomatic Zenker's diverticulum underwent endoscopic treatment under short general anesthesia applied CO2 laser. The mean age of the patients was 73.2 years (range: 54 to 97 yrs). All patients had significant symptoms such as dysphagia (15 patients out of 17). All patients were clinically evaluated after the procedure. RESULTS: The endoscopic incision was performed in one session per patient. Symptoms and dysphagia disappeared in all patients except one (dysphagia). Two complications (one cervical emphysema, one fistula) were managed clinically. Mortality was 0%. Mean follow-up was 17 months. There was no recurrence of dysphagia, all patients remained asymptomatic. CONCLUSIONS: Rigid endoscopic treatment of symptomatic Zenker's diverticulum applied with laser CO2 is an efficient and safe method. It should be considered as an alternative therapy for Zenker's diverticulum, especially for patients at a high surgical risk.     

Well differentiated cerebellar tissue within a mature cystic teratoma

OBJECTIVE: Oesophageal self-expanding metal endoprostheses (SEMS, or stents) are recognized as a safe means of palliating dysphagia caused by malignancy. Stent designs that have covered or uncovered walls are now available. The purpose of this study was to compare the outcome of use of these two designs. DESIGN: Thirty consecutive cases were reviewed. All the patients had been referred over a period of 25 months for palliation of dysphagia caused by malignant obstruction. Either a covered or an uncovered stent was placed in each patient. Palliation of dysphagia, 30 day mortality, mean survival time, and the number of endoscopic re-interventions required, were assessed. RESULTS: Uncovered Ultraflex stents were used in 14 patients, and Schneider Wallstents were used in 16 patients. Dysphagia improved by one grade or more in 69% of patients. The 30 day mortality was 27%, with an overall mean survival time of 99 days. There was no significant difference between the two groups for these three parameters. Ten patients needed a total of 28 repeat endoscopic procedures to maintain stent patency, with overall rates for each group of 1.64 procedures per patient, for uncovered stents, compared with 0.31 for covered stents (significant at the P < 0.05 level). The number of repeat procedures increased with survival time. CONCLUSION: The use of covered self-expanding metal oesophageal endoprostheses is associated with a significant reduction in the need for endoscopic reintervention after stent placement.     

Treatment of advanced gastroesophageal reflux disease with Collis gastroplasty and Belsey partial fundoplication

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.     

Permanent endoprostatic prostheses in patient with obstruction caused by benign hyperplasia of the prostate

Presentation of the results obtained using the intraprostatic prosthesis UroLume in 78 patients wit BPH obstruction, 69 of which presented high surgical risk (ASA IV). Mean age was 79.8 years (r: 62-93). All patients carried urethral catheters, except 4 (5.1%) who had a provisional metal coil that required replacement. Prosthesis were implanted successfully in 72 cases (93.3%). The most significant exclusion criterion was an excessive length of prostate urethra. Mean follow-up was 15.3 months (r: 3-38). Mean maximum flow at 1 year after implant was 12.7 mL/sec; mean symptoms score (I-PSS score) was 6.2 points and in most prosthesis, epithelization had taken place. Three patients required implant of another prosthesis, either during the same surgical procedure (1 case) or later due to retention or dysuria (2 cases). Due to acute urine retention (AUR) during the immediate postoperative, resection of the middle lobe was performed in one case while a second case required late resection of intraluminal hyperplastic tissue. Three patients (4.1%) had haematuria that forced hospital admission some months after the implant, and three cases (4.1%) required removal of the prosthesis; at patient's request (1 case), due to calcification (1 case) and for stress incontinence (1 case). After a follow-up of over three years, it can be concluded that the UroLume prosthesis is an effective alternative to TUR in patients at high surgical risk.     

Systemic clotting activation by low-grade endotoxaemia in liver cirrhosis: a potential role for endothelial procoagulant activation

Laparoscopic fundoplication is technically feasible in treating gastroesophageal reflux disease (GERD). Although medication is the primary treatment for GERD, not all patients respond completely or are able to adhere to a medical regimen. In the present series, 59 patients were laparoscopically treated for GERD at three centers using a standardized technique. All patients had been medically treated prior to referral, although 84 per cent had heartburn and 2 per cent had laryngitis despite 20 to 40 mg/day of omeprazole. Fifteen per cent of patients were intolerant of or would no longer take omeprazole. Patients were evaluated by esophageal manometry (in 100%) and 24-hour pH studies (in 66%). Seventy-six per cent of patients had lower-esophageal sphincter pressure <15 mm Hg. Five patients had low esophageal body peristaltic pressures (<35 mm Hg). These patients underwent Toupet partial fundoplication, whereas 54 patients underwent Nissen fundoplication. Mean operative time was 158 +/- 7 minutes, and three patients (5%) were converted to an open procedure. Operative complications were minor and occurred in 13 per cent. In 45 patients evaluated 1 year after surgery, heartburn had resolved in 98 per cent. Thirty-nine of 56 patients (70%) had mild early (<1 month postoperatively) dysphagia, and 9 (19%) had severe early dysphagia, which improved in 7 after nonoperative dilatation. Two of these had continued mild dysphagia. Two patients had severe dysphagia and were laparoscopically converted from Nissen to Toupet fundoplications, which resulted in marked improvement. Early gas bloat symptoms occurred in 45 per cent and dropped to 5 per cent at 1 year. Laparoscopic treatment of GERD is safe and effective in preventing reflux symptoms. Although mild dysphagia occurs after the procedure, this is transient in most patients. Patients with severe dysphagia can be treated with nonoperative dilatation or laparoscopic partial fundoplication and maintain the antireflux characteristics of the wrap.     

"Direct" indirect training approach to rehabilitation of dysphagia patients--a new method for rehabilitation with a feeding-tube

The rehabilitation approaches for training patients with dysphagia consist of both direct approaches (eating training) and indirect approaches (basic training for dysphagia patients without food). On the other side, some recent reports revealed that some patients who had had severe dysphagia were improved while the feeding approach was with a naso-gastic tube and an oral-esophago feeding tube. So we thought that stimulation of these feeding tubes for the pharynx and the larynx would produce some useful reactions for dysphagia patients. We developed a new method for the rehabilitation of such patients. The technique is the repeated insertion of the naso-gastric tube at the time of the swallowing motion, which we called the "direct" indirect training approach. Sometimes, other basic training procedures for dysphagia patients are admissible. We treated 26 patients by this method. The patients included those with disorders of the corticobulbar tract (n = 11), a disorder of the medulla (n = 5), a disorder of the peripheral nerve (n = 7), and a long-lasting disused state (n = 3). Twenty-four patients were improved and could eat orally without major problems. Laryngeal elevation curves of this approach in the pre- and post-therapeutic states revealed that the threshold of the swallowing reflux was lower, and the swallowing actions were changed dynamically, and became more useful.     

Malignant esophageal-respiratory fistula and esophageal stenosis treated with a Gianturco-Z-stent

Oesophago-respiratory fistula in most instances in a complication of advanced malignant tumours of the oesophagus or the lung. In our patient group eleven oesophago-respiratory and one gastro-respiratory fistulas were encountered. Three patients were operated upon. In one of them with achalasia, early oesophageal carcinoma was discovered in the background of the fistula. Two patients had fistulas without of oesophageal narrowing, therefore, stent implantation into the trachea and bronchus was performed. One of them was previously managed endoscopically with lyodura plug and fibrin glue, but only temporary occlusion of the fistula was obtained. In five patients, seven conventional oesophageal prosthesis (6 Cook, 1 Rüsch) were used to close the fistulas. In one of these patients, three oesophago-respiratory fistulas developed one after the other at the level of the prosthesis funnel. They were closed with three prostheses connected with short silicone tubes. In the last two patients, Gianturco-Z stent was employed. Its advantages over the plastic prostheses include small basic and lager final luminal diameter, lesser predilatation, easier implantation, lower complication and mortality rate. The silicone coated and double funnel stent with expansile force is effective in fistulas closure. On implantation, stent shortening in minimal, allowing precise placement of the stent even in proximal malignant oesophageal stenosis with oesophago-bronchial fistula. The high price of the stent is compensated for by the lower complication rate, shorter hospitalization and subsequent reduction is hospital expenses. Therefore these metal stents should be financed by the National Health Service, at least in specialized centers for managing patients with dysphagia.
