We report the case of a 65-year-old woman with a 10-year history of dysphagia, regurgitation, cough, and 10-kg weight loss caused by an epiphrenic diverticulum associated with esophageal achalasia managed with a laparoscopic approach. A preoperative barium swallow showed a dilated sigmoid esophagus with a 6-cm epiphrenic diverticulum. Esophageal manometry confirmed the absence of peristalsis in the esophageal body. We performed a laparoscopic diverticulectomy and a 7-cm distal esophageal myotomy with a Dor fundoplication. The postoperative course was uneventful. On the third postoperative day a barium swallow showed no leak, and the patient started oral intake. She was discharged home 5 days after the operation free of symptoms and tolerating a soft diet. Sixteen months after surgery, she was asymptomatic and had gained 8 kg. A barium swallow showed a normal-size esophagus with regular emptying. We reaffirm the feasibility, safety, and efficacy of the laparoscopic diverticulectomy and distal myotomy with Dor fundoplication to manage epiphrenic diverticula resulting from esophageal achalasia.

Esophageal pH monitoring identifies some patients who have physiologic amounts of esophageal acid exposure but have a strong correlation between symptoms of esophageal reflux events. These patients with symptomatic physiologic reflux probably have enhanced sensory perception of reflux events and may be difficult to control with acid-suppressive therapy. Little is known about the role of fundoplication in such patients. Patients with no endoscopic evidence of gastroesophageal reflux disease and a normal 24-hour pH composite score (<22.4 in our laboratory), but a symptom index (SI = number of symptoms with pH <4/total number of symptoms) greater than 50% were offered laparoscopic fundoplication if acid-suppressive therapy was unsatisfactory. This group comprised 18 (4%) of 459 patients undergoing fundoplication at our institution. Heartburn, dysphagia, and reflux symptoms were scored on a scale of 0 to 10 with patients on and off medicine preoperatively, and at a mean of 7.2 months (range 1 to 32 months) postoperatively. The 18 patients with symptomatic physiologic reflux (6 males and 12 females) had heartburn as a major complaint. Preoperative response to proton pump inhibitors for heartburn was 72% and for all symptoms was 60%. The group had a mean pH composite score of 14 (range 4 to 22). The symptom used to calculate the symptom index was heartburn in 12 patients, regurgitation in three, chest pain in two, and cough in one. An average of 18 symptoms (range 2 to 56) were recorded. The mean symptom index was 82% (range 50% to 100%). A Nissen fundoplication was performed in nine patients and a Toupet fundoplication in nine. Surgery was successful (>90%) in alleviating reflux symptoms in 14 patients and partially successful (>75%) in three of the remaining four patients. Gas bloat and dysphagia were seen in one patient each. Fundoplication is effective at relieving reflux symptoms in carefully selected patients with symptomatic physiologic reflux, with minimal side effects.

Achalasia cardia is a disease of adolescents and is rare in children. In total, 12 children with primary achalasia, with a mean age of 10.8 +/- 2 years, were prospectively evaluated for the efficacy of a 30-mm-diameter Rigiflex balloon for relief of symptoms and weight gain after 1 and 6 months of follow up. The 12 children were evaluated and treated for achalasia, with pneumatic balloon dilatation, from January 1998 to December 2000. They were studied for basal, 1-, and 6-month post-dilatation composite symptoms for dysphagia, regurgitation, night cough and heartburn. Basal and 5-min post-dilatation barium swallow were obtained to compare barium height and width for efficacy of dilatation and to evaluate for complications. There were no complications. Barium height, width, composite symptom score and weight improved significantly up to the 6-month follow up. Rigiflex balloon dilatation of 30-mm diameter is safe and effective in children with achalasia.

In general terms, all patients who undergo a laparoscopic fundoplication procedure should have objective evidence of gastroesophageal reflux. However, occasionally patients without objective evidence of reflux disease are referred for surgery. This study assessed the outcome of a highly selected group of patients who underwent laparoscopic fundoplication without objective evidence of reflux at either preoperative endoscopy or pH monitoring. Data from all patients undergoing laparoscopic fundoplication in our department over a 9-year period from December 1991 to January 2001 were collected prospectively. From a total of 1,003 patients, a subgroup of 15 patients was identified who had no evidence of ulcerative oesophagitis at endoscopy or abnormal reflux on 24-h pH monitoring. Eight of these patients had typical symptoms of reflux (four had predominantly heartburn, four had predominantly volume regurgitation) and seven patients had atypical symptoms such as cough, bloating, chest pain, or sore throat. All patients had tried medication for acid suppression before surgery, with five gaining little or no benefit. The mean acid exposure time was 2% (range 0.1-3.6%). A correlation between typical symptoms and reflux events of over 50% was noted in three patients. All patients underwent laparoscopic fundoplication, with one conversion to an open procedure. Mean patient satisfaction score (0-10 linear score) was 8.7 at 3 months and 1 year postoperatively. Three patients failed to improve following surgery. These three all had atypical symptoms, a symptom correlation of less than 50% with acid reflux on pH monitoring, and two of the three had a poor response to medication. All other patients benefited symptomatically from surgery. We concluded that the absence of objective evidence of reflux should not always preclude patients from a laparoscopic fundoplication. Carefully selected patients with typical reflux symptoms can have a good outcome. However, patients who do not have typical symptoms and who respond poorly to acid suppression are not likely to benefit from surgery.

Acquired TEF is a rare complication that can occur from a variety of causes. The most common etiology of nonmalignant TEF is as a complication of intubation with cuff-related tracheal injury. Most patients present with increased secretions, pneumonia, and evidence of aspiration of gastric contents while the patient is on mechanical ventilation. When diagnosed after extubation, the most frequent sign of TEF is coughing after swallowing. A high index of suspicion is required in patients at risk for developing a TEF. The diagnostic evaluation is by bronchoscopy and esophagoscopy. When the diagnosis has been made, the immediate goal should be to minimize tracheobronchial soilage by placing the cuff of a tracheostomy tube distal to the fistula. Reflux of gastric contents is diminished by placement of a gastrostomy tube, and adequate nutrition is facilitated by inserting a jejunostomy tube. Surgical correction is required because spontaneous closure is rare, but surgery should be postponed until the patient is weaned from mechanical ventilation because positive pressure ventilation after tracheal repair carries an increased risk of anastomotic dehiscence and restenosis. An anterior cervical collar incision can be used for most cases of post-intubation TEFs. The esophagus should be closed in two layers over a nasogastric tube and buttressed with a pedicled strap muscle flap. If the tracheal defect is small, primary repair can be employed. In most cases, however, the best results can be achieved with tracheal resection and reconstruction. The patient should be extubated at the completion of the case, if possible. With this strategy, as first described by Grillo and colleagues [27], single-stage repair can be performed safely and with a high success rate. Malignant TEFs cannot be cured because of the underlying incurable disease process. As with nonmalignant TEFs, the principal complications are tracheo-bronchial contamination and poor nutrition. Without prompt palliation, death occurs rapidly, with a mean survival time of between 1 and 6 weeks in patients who are treated with supportive care alone. The most common primary tumor causing malignant TEF is esophageal carcinoma. The other frequent cause is lung cancer. Patients present with signs and symptoms typical of TEF, including coughing after swallowing. Diagnosis is made by barium esophagography, and the location and size of the fistula is determined by bronchoscopy and esophagoscopy. Treatment must correct the two problems of airway contamination and poor nutrition. The most effective treatments are esophageal bypass and esophageal stenting. Bypass is demonstrated to resolve respiratory soilage and allow fairly normal swallowing, but it should be reserved for patients who can tolerate a major operation. Stenting can be offered to nearly all patients regardless of their physiologic condition. Stenting also limits aspiration and allows swallowing. Esophageal exclusion is rarely indicated in the current era of familiarity with stenting techniques. Direct fistula closure and fistula resection do not yield satisfactory results. Radiation therapy and chemotherapy combined might offer a survival benefit compared with supportive care alone. The complication of TEF secondary to malignancy is a devastating problem that carries a bleak prognosis, but when it is performed promptly after the diagnosis of a malignant TEF, esophageal bypass or stenting improves survival and quality of life for these unfortunate patients.

The association between gastroesophageal reflux disease (GERD) and extraesophageal disease is often referred to as extraesophageal reflux (EER). This article reviews EER, discussing epidemiology, pathogenesis, diagnosis, and treatment with a focus on the most studied and convincing EER disorders-asthma, cough, and laryngitis. Although EER comprises a heterogeneous group of disorders, some general characterizations can be made, as follows. First, although GERD's association with extraesophageal diseases is well-established, definitive evidence of causation has been more elusive, rendering epidemiological data scarce. Secondly, regarding the pathogenesis of EER, 2 basic models have been proposed: direct injury to extraesophageal tissue by acid and pepsin exposure or injury mediated through an esophageal reflex mechanism. Third, because heartburn and regurgitation are often absent in patients with EER, GERD may not be suspected. Even when GERD is suspected, the diagnosis may be difficult to confirm. Although endoscopy and barium esophagram remain important tools for detecting esophageal complications, they may fail to establish the presence of GERD. Even when GERD is diagnosed by endoscopy or barium esophagram, causation between GERD and extraesophageal symptoms cannot be determined. Esophageal pH is the most sensitive tool for detecting GERD, and it plays an important role in EER. However, even pH testing cannot establish GERD's causative relationship to extraesophageal symptoms. In this regard, effective treatment of GERD resulting in significant improvement or remission of the extraesophageal symptoms provides the best evidence for GERD's pathogenic role. Finally, EER generally requires more prolonged and aggressive antisecretory therapy than typical GERD requires.

Chronic cough is a common and distressing symptom. A novel algorithm has been developed for the management of chronic cough, in which an assessment of clinical probability of disease determines the need to proceed to investigation. In this study, the performance of this algorithm in clinical practice was prospectively evaluated. A total of 131 consecutively referred patients (86 females) whose principal presenting symptom was a cough of duration >8 weeks were studied. Their age (median (range)) was 60 (16-88) yrs and cough duration 5.9 (0.2-65) yrs. A cause of cough was established in 93% of cases. The most frequent diagnoses were asthma (24% of cases), gastro-oesophageal disease (22%), post-viral cough (8%), bronchiectasis (8%) and interstitial lung disease (8%). Primary pulmonary disease was significantly more likely in patients with a productive cough and in patients with an abnormal chest radiograph. Only a small proportion (<8%) of patients had multiple causes of cough. The probability of treatment started on the basis of a high clinical suspicion of either asthma, gastro-oesophageal disease or rhinitis being successful was 74%. Overall, 26% of the patients were managed successfully without the need for any form of investigation other than chest radiography and spirometry. Use of the algorithm resulted in identification of the cause of cough and successful treatment in the large majority of cases. It is concluded that this protocol has the potential to improve management by providing a structured approach, reducing the number of investigations performed, and minimising unnecessary delays in treatment.

Pneumatic balloon dilatation is the treatment of choice for esophageal achalasia. Rigiflex (Microvasive, Watertown, MA) polyethylene balloon dilators have been used with varying success and complications. The aim of this study was to evaluate the efficacy of graded balloon dilatation, to achieve symptomatic improvement in patients with achalasia. From January 1987 until the end of December 2003, 300 patients were evaluated and treated for achalasia, with 30 mm balloons. Patients who did not achieve satisfactory symptomatic responses during follow up underwent repeat dilatation with 35-mm balloons. They were studied at the onset then at 1 and 6 month intervals and then yearly for postdilatation symptom evaluation for dysphagia, regurgitation, night cough and heartburn. Baseline and 5-min postdilatation barium swallow studies were obtained to compare barium height and width for efficacy of dilatation and to evaluate for complications. No patients developed cancer of the esophagus in 16 years follow up. Barium height, width, composite symptom score and weight improved significantly during follow up. Two patients, who needed repeat dilatation with 35-mm balloons, developed esophageal perforation; one was successfully managed with intensive medical care management, whereas the other patient died despite surgical intervention. The authors conclude that pneumatic balloon (Rigiflex) dilatation for achalasia of the esophagus is a successful first option, when applied in an incremental balloon size to achieve desired results in symptomatic relief.

We report on a 75-year-old woman with an isolated colonic hernia through the esophageal hernia. The patient had suffered from cough, palpitation and dyspnea. A chest X-ray showed a colon loop gas in the mediastinum. Simultaneous barium swallow and enema showed the herniation of the only transverse colon into the mediastinum and displacement of the distal esophagus by the migrated colon. The patient underwent an open-mesh cruroplasty and a Hill's posterior gastropexy. The postoperative clinical course was uneventful. The patient has cessation of the symptoms. To our knowledge, there are only five reports presenting patients with isolated colonic hernia through the esophageal hiatus, including our case.

Two techniques for treatment of Zenker's diverticulum, endoscopic stapler-assisted esophagodiverticulostomy and open cricopharyngeal myotomy by transcervical approach, were compared with regard to patient satisfaction and quality of life. Between January 1994 and December 2004 a total of 47 patients with Zenker's diverticulum underwent surgery in our department. Besides the usual retrospective evaluation of details of surgery, all patients were sent a questionnaire on their actual complaints and quality of life according to the Gastrointestinal Quality of Life Index (GIQLI). Twenty patients had the endoscopic procedure (Group A), and 27 the open procedure (Group B). The preoperative symptoms were dysphagia in 96%, regurgitation of undigested food in 60%, cough in 19%, and pneumonia caused by recurrent aspiration in 9%. The length of surgery was on average 32 min (range 5-70 min) in Group A and 106 min (range 45-165 min) in Group B, and the length of hospital stay was 5.5 days (range 1-10 days) and 12.3 days (range 7-25 days), respectively. The results of the questionnaire showed that the preoperative symptoms had disappeared in up to 83%, and 91% in Group A and 100% in Group B would be willing to undergo surgery again. The mean GIQLI was 123 points in Group A and 118 points in Group B (healthy volunteers in the literature, 125 points). Both techniques showed good results in a long-term follow-up with regard to relief of symptoms and patient satisfaction. Both groups had an excellent Gastrointestinal Quality of Life Index, comparable to that of a healthy standard population.
