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.

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.

The purpose of this study was to evaluate the efficacy of a specially selected cornstarch-supplemented formula on clinical symptoms, gastric emptying and weight gain in infants with regurgitation. We performed a prospective randomised trial evaluating the therapeutic efficacy of two different formula feedings (cornstarch-thickened formula, group A; 25% strengthened formula, group B) in 81 young infants with regurgitation/vomiting > or = 3 times/day. A Tc-99 m milk scintigraphy was performed at inclusion and after 2 months to quantify gastric emptying time; all studied infants underwent a 2-month period of clinical follow-up evaluating regurgitation and body weight gain. At inclusion, group A and B had a similar age and weight. After the 2-month period of intervention, regurgitation and vomiting had both greater decrease (both P < 0.001 at 1 and 2 months) in group A (from a score of 4.19 +/- 1.71 to 0.93 +/- 0.42) than in group B (from a score of 4.15 +/- 1.68 to 2.89 +/- 1.16). Non-regurgitation symptoms (irritability, cough, choking, night-waking) decreased (P = 0.045 at 1 month and 0.017 at 2 months) in group A (from a score of 18 at baseline to 3 after 8 weeks) as compared to group B (from a score of 18 at baseline to 11 after 8 weeks). Weight increased more in group A (29.1 +/- 3.9 g/day over 8 weeks) versus group B (23.6 +/- 3.5 g/day over 8 weeks) (P < 0.01 at 1 and 2 months) Gastric emptying improved significantly in group A as compared with group B (all P < 0.001 for T1/2, and residual volume at 60 and 90 min). Ingested feeding volume was significantly larger in the group receiving cornstarch-thickened formula, both at 4 weeks (109.4 +/- 24.5 vs. 98.5 +/- 23.6 mL/meal) (P: 0.042) and at 8 weeks (137.6 +/- 27.9 vs. 115.7 +/- 26.5 mL/meal) (P < 0.001). Cornstarch-thickened formula feeding decreases the frequency of regurgitation/vomiting, provides better body weight gain and has an accelerated gastric emptying in comparison to a 25% strengthened regular formula in infants with regurgitation.

The purpose of this study was to compare the outcomes of patients with different types of gastroesophageal reflux disease (upright, supine, or bipositional) after laparoscopic Nissen fundoplication and determine if patients with upright reflux have worse outcomes. Two hundred and twenty-five patients with reflux confirmed by 24-h pH monitoring were divided into three groups based on the type of reflux present. Patients were questioned pre- and post-fundoplication regarding the presence and duration of symptoms (heartburn, regurgitation, dysphagia, cough and chest pain). Symptoms were scored using a 5-point scale, ranging from 0 (no symptom) to 4 (disabling symptom). Esophageal manometry and pH results were also compared. There was no statistically significant difference in lower esophageal sphincter length, pressure or function between the three groups. There was no significant difference in any of the postoperative symptom categories between the three groups. The type of reflux identified preoperatively does not have an adverse effect on postoperative outcomes after Nissen fundoplication and should not discourage physicians from offering antireflux surgery to patients with upright reflux.

Megaoesophagus resulting from achalasia is a rare but serious cause of airway obstruction. The exact aetiology remains unclear. Achalasia normally presents as weight loss, dysphasia and regurgitation but frequently considerable oesophageal distension can occur without complain and very rarely cause of achalasia presents with stridor or respiratory distress. The authors presents a 19 -year old young lady who had respiratory symptoms and had been treated as a cause of chronic asthma, was found by us to have oesophagus achalasia. She had complained of cough, dispneia and had a pulmonary function studies that showed a severe airway obstruction. After surgery the symptoms disappeared and she had a marked improvement in the flow-volume curve. Oesophagus achalasia should be considered as one of the differential diagnoses of airway obstruction.

In this article, we reviewed our experience of treatment of the delayed intrathoracic nonmalignant esophageal perforation employing modified intraluminal esophageal stent. Between February 1990 and August 2006, eight patients were included in this study. Five patients experienced sepsis. The interval time between perforation and stent placement ranged from 36 h to 27 days (average, 8.6 days). Esophageal stenting and throracotomy for foreign body removal were performed in four patients. The remaining four patients underwent stent placement and thoracostomy. Nutrition was initiated through gastrostomy after 7 to 10 days after the stenting. The stent was removed after the patients resumed oral intake of food and the esophagogram showed that perforation was closed. There was no death in this group. Signs of sepsis remitted 1 week after stent placement. Complications included stress ulcer, stimulative cough, and pneumonia each. Stent removal ranged 32 to 120 days (average 66.7) after its placement. The stent was kept in place for 4 months to prevent formation of esophageal stricture in one patient with caustic esophageal burns. The follow-up was completed in all the patients. The mean follow-up period was 59 months (range 12-180). One patient with caustic esophageal burn underwent cicatricial esophagectomy and gastric transposition 3 years later due to the esophageal stricture. Barium swallow demonstrated that there was a diverticulum-like outpouching in one patient and slight esophageal stricture at T2 and T3 level in another. One patient developed reflux esophagitis 5 years after stent removal. All the patients finally had a normal intake of food. Modified esophageal stenting is an effective method to manage the delayed intrathoracic esophageal perforation. Prevention of stent migration and its convenient adjustment might be the major advantages of this method.

Twenty-four-hour multichannel intraluminal impedance and pH (MII-pH) esophageal monitoring detects both acid and nonacid gastroesophageal reflux episodes. The MII-pH catheter contains six impedance segments placed 3, 5, 7, 9, 15, and 17 cm above the lower esophageal sphincter (LES). A pH electrode at 5 cm above the LES identifies the type of reflux, i.e. acid or nonacid. Patients with acid and nonacid reflux exhibit typical and atypical symptoms often within 5 min following a reflux episode. The aim of this study is to compare the timing of symptoms after reflux episodes in patients with acid and nonacid reflux. Methods include a review of 70 MII-pH tracings (42 females, mean age 40, range 18-85 years) either on (50 points) or off (20 points) acid suppression therapy. Typical (heartburn, regurgitation) and atypical (cough) symptoms with acid or nonacid reflux episodes detected by impedance were analyzed. Symptoms were considered positive with acid reflux if there was a pH drop to <4, plus an MII detected a reflux episode and with nonacid reflux if pH remained >4 and MII detected a reflux episode. The timing of the symptom after each reflux episode was recorded. Symptom perception occurred significantly sooner after acid versus nonacid reflux (P < 0.05). Acid reflux episodes are more likely to be perceived in the first 2 min following the reflux episode. Patients with acid reflux are likely to perceive symptoms earlier, and symptoms with acid and nonacid reflux may be produced by different mechanisms.
