Although there are studies showing that the amplitude of contraction in the distal esophageal body may be lower in gastroesophageal reflux (GER) disease than in asymptomatic subjects, there are no data about proximal striated muscle contraction in this disease. We studied the esophageal contraction 2 or 3 cm below the upper esophageal sphincter in response to swallowing a 5-ml bolus of water in 122 consecutive patients submitted to esophageal manometry who complained of heartburn and acid regurgitation. Sixty-nine had esophagitis seen at endoscopy. Thirty-three also complained of dysphagia. No patients had esophageal stenosis, esophageal motility abnormalities in distal esophagus, chest pain, or extraesophageal manifestations of GER. We also studied 20 patients with systemic sclerosis (SSc), a disease with no involvement of striated muscle. When we measured the amplitude, duration, and area under the curve (AUC) of the proximal esophageal contraction, we did not find any differences (P > 0.05) between patients with esophagitis (N = 69) or without esophagitis (N = 53), with dysphagia (N = 33) or without dysphagia (N = 89), with mild (N = 55) or severe (N = 14) esophagitis, or younger than 40 years (N = 45) or older than 60 years (N = 19). There was also no difference between patients with GER symptoms and patients with SSc (P > 0.05). We conclude that patients with GER symptoms with or without esophagitis and with or without dysphagia have similar esophageal striated muscle contractions.

In this article we analyze our experience of surgical treatment of hiatal hernia, complicated with gastroesophageal reflux. We operated 134 patients with hernia hiatus esophagi, complicated with gastroesophageal reflux, from 03.1998 till 10.2001. One hundred twenty-six Nissen and 8 Toupet laparoscopic gastrofundoplications were performed. We evaluated clinical signs of gastroesophageal reflux, performed endoscopy and esophageal biopsy with histological examination and stomach X-ray examination with barium meal before the operation. Esophagus and stomach X-ray examination with water contrast on the first day after operation were performed in order to evaluate the position and function of created wrap. We also analyzed intraoperative and postoperative complications. Long-term follow-up (12 months) was obtained by using a structured questionnaire. We evaluated heartburn, dysphagia, regurgitation and patient's satisfaction of surgery. RESULTS. Postoperative complications rate was 8.96%. Eighty-two percent of our patients completed our questionnaire. Ninety-one percent of patients had no heartburn signs, 95.5% any signs of regurgitation. Eighty-three percent of our patients were satisfied with our performed laparoscopic gastrofundoplication. We performed 6 refundoplications, when gastroesophageal reflux clinical signs renewed shortly after operation. CONCLUSIONS. Laparoscopic gastrofundoplication is a safe and effective treatment of hernia hiatus esophagi, complicated with gastroesophageal reflux. Operation success was about 90% in our study. Recurrences are more frequent in elderly patients or those with long disease anamnesis. Refundoplications can be successfully done laparoscopicaly as well.

The purpose of this study was to evaluate the efficiency and safety of oesophageal balloon dilatation in strictures secondary to surgical treatment of oesophageal atresia in 25 children. Patients comprised 15 males and 10 females, aged 1-36 months. Median age was 4 months (interquartile range (IQR)=19). The strictures were more than 50% of oesophageal lumen and the delay from surgical treatment to balloon dilatation varied from 1 month to 36 months. Associated gastroesophageal reflux was noted in 15 patients. All procedures were performed under sedation using fluoroscopic guidance. Balloons of increasing diameter, 4-20 mm were used. Water soluble contrast swallow was performed after each dilatation session. A total of 115 balloon dilatation sessions were performed with a range of 1-14 procedures per patient (median 4 dilatations, IQR=4.5). Dilatation relieved the stricture in all patients over a follow-up period varying from 4 months to 33 months. The best results were noted in children under 6 months, who needed two or few dilatation sessions, with relative risk (RR) of 0.52 and 95% confidence interval of 0.29-0.92. The presence of associated gastroesophageal reflux indicated a high risk (RR of 12, p<0.001) for undergoing more than two balloon dilatation sessions. The only serious complications observed were two cases of oesophageal perforation, which were treated conservatively. Fluoroscopically guided balloon dilatation is a safe and effective treatment in the management of strictures secondary to surgical repair of oesophageal atresia, especially when started early (within 6 months of surgery) and not associated with gastroesophageal reflux.

Five isonitrogenous diets (1-5) with 40% protein using oilcakes as protein sources were formulated and fed to Cirrhinus mrigala fingerlings maintained both under laboratory and field conditions. Water soaking of oilcakes for 24 h before incorporation in the diets helped in the reduction of antinutrient factors (phytase and tannins). Live weight gain in fish fingerlings fed on a diet containing groundnut oilcake (GNOC) was significantly (P < 0.05) enhanced in comparison to the other dietary treatments when examined at the end of a feeding schedule. Laboratory studies have further revealed that APD, PER, GPR and GER values were significantly (P < 0.05) enhanced, while those of feed conversion ratio were significantly (P < 0.05) reduced in fish fed on diet 1 containing GNOC. An analysis of water samples collected at two hourly interval from the aquaria revealed low levels of total ammonia (N-NH4+) excretion and reactive phosphate (O-PO4) production in fish fed on diet 1. Proximate carcass composition also revealed high accumulation of protein, fat, energy and phosphorus in fingerlings fed on a diet containing GNOC. Even in field studies a significant (P < 0.05) increase in mean fish weight gain and specific growth rate (SGR% d(-1)) was observed in fingerlings fed on diet 1, followed by canola (2), sunflower (3), mustard oilcake (4) and sesame (5). Water and sediment quality characteristics also correlated well with fish growth.

The aim of this study was to define the clinical presentation, motility characteristics, and prevalence and patterns of gastroesophageal reflux in patients with hypertensive lower esophageal sphincter (HTLES). HTLES was defined by a resting pressure measured at the respiratory inversion point on stationary manometry of greater than 26 mm Hg (ninety-fifth percentile of normal). One hundred consecutive patients (80 women, 20 men; mean age 54.7 years, range 23 to 89 years), diagnosed with HTLES at our institution between September 1996 and October 1999, were studied. Patients with achalasia or other named esophageal motility disorders or history of foregut surgery were excluded, but patients with both HTLES and "nutcracker esophagus" were included. The most common symptoms in patients with HTLES were regurgitation (75%), heartburn (71%), dysphagia (71%), and chest pain (49%). The most common primary presenting symptoms were heartburn and dysphagia. The intrabolus pressure, which is a manometric measure of outflow obstruction, was significantly higher in patients with HTLES compared to normal volunteers. The residual pressure measured during LES relaxation induced by a water swallow was also significantly higher than in normal persons. There were no significant associations between any of the relaxation parameters studied (residual pressure, nadir pressure, duration of relaxation, time to residual pressure) and either the presence or severity of any symptoms or the presence of abnormal esophageal acid exposure. Seventy-three patients underwent 24-hour pH monitoring, and 26% had increased distal esophageal acid exposure. Compared to a cohort of patients with gastroesophageal reflux disease but no HTLES (n=300), the total and supine periods of distal esophageal acid exposure were significantly lower in the patients with HTLES and abnormal acid exposure. Patients with HTLES frequently present with moderately severe dysphagia and typical reflux symptoms. Approximately one quarter of them have abnormal esophageal acid exposure on pH monitoring. Patients with HTLES have significantly elevated intrabolus and residual relaxation pressures on liquid boluses, suggesting that outflow obstruction is present.

The prescription of peritoneal dialysis should be individualized based on parameters of tolerance and adequacy. Determination of the intraperitoneal fill volume is essential for optimal patient care. Fill volume enhancement is a factor of exchange surface area recruitment: the wetted, contact peritoneal dialysis membrane. Nevertheless, fill volume enhancement can also lead to patient discomfort, with the potential risk of too high an intraperitoneal pressure (hernia, gastro-esophageal reflux). The perception of the individual patient is also a subjective parameter of fill volume tolerance assessment. In contrast, measurement of the hydrostatic intraperitoneal pressure (IPP, cmH(2)O) allows an objective approach to fill volume tolerance. From our clinical experience of more than 10 years of IPP measurements in child care, we can give a recommendation for normal values in children: less than 18 cm of water, usually between 5 and 15 cm, correlated to the intraperitoneal fill volume (naturally), but individually taking into account age, gender, "accustomization" and overall body mass index.

In adults, esophageal motor responses facilitate forward, or aboral, transit during swallowing, and protect the aerodigestive tract during retrograde movement of the bolus, which may occur with gastroesophageal reflux. It is unclear in the pediatric literature whether the activation of appropriate esophageal motor defense responses occurs during these events in infants. This investigation therefore studied the esophageal motor responses during the basal state and upon esophageal stimulation in infants. Using the water-perfusion manometry technique and a specially designed manometric catheter, 3 likely mechanisms that may protect the aerodigestive tract were recognized: secondary peristalsis, esophago-upper esophageal sphincter contractile reflex, and esophagodeglutition response.

Zenker's diverticulum (ZD) is a rare pathology, with a prevalence of between 0.01% and 0.11%. Definitive diagnosis of ZD can be accomplished by contrast radiographic examination (barium oesophagogram, BE); oesophageal manometry (ME) is recommended mainly for those patients suffering from dysphagia and/or gastro-oesophageal reflux. The aims of the present study were to assess whether oropharyngo-oesophageal scintigraphy (OPES) is able (a) to visualise ZD and (2) to demonstrate the corresponding alteration in the swallowing phases. We studied 16 patients (nine male, seven female, mean age 67.4 years), and 17 healthy volunteers (ten male, seven female, mean age 53 years) as a control group. All the patients underwent ME, BE and OPES. Nine patients underwent surgery and six of them were re-evaluated after 6 months. We administered 10 ml of water with 37 MBq of technetium-99m colloid through a straw, acquiring 480 sequential images (0.125 s/frame for a total of 60 s) with the patient standing in front of the gamma camera in the 80 degrees right anterior oblique position. Two static images were performed at the end of the dynamic phase, before and after ingestion of 100 ml of unlabelled water to evaluate the presence of inflammation (persistence of radioactivity in the diverticulum or oesophagus). Study of the sequential scintigraphic images and time-activity curves permitted both qualitative (diverticulum visualisation, multiple deglutitions, reflux, presence of inflammation) and quantitative analyses [oral, pharyngeal and oesophageal transit times and retention indexes, tracheal aspiration percentage] of swallowing disorders. OPES showed a good correlation with the results of other diagnostic techniques usually performed in patients with this pathology, and especially with ME in the evaluation of oropharyngeal phase disorders. Furthermore, OPES is a sensitive and simple technique that is well tolerated and entails a low irradiation dose for patients.

Fifteen cases of intractable chronic esophagitis due to gastroesophageal reflux were treated with a continuous intraesophageal antacid drip. A proprietary antacid preparation, Gelusil or monalium hydrate (Riopan), in a concentration of one part of antacid to nine parts of water, was infused into the mid-esophagus through a polyethylene tube with an internal diameter which admits a No. 18 blunted needle. Patients are not confined to bed while the drip is in progress. If the flow is constant and the end of the tube is below the cricopharyngeal sphincter, patients do not experience discomfort even if the drip is administered continuously for several days.Results indicate that remission of symptoms can be achieved in almost every patient, even those who have previously failed to respond to oral antacid therapy.

A 81-year-old man, who had been diagnosed in multiple cerebral infarction and Alzheimer's disease, was followed up in his local clinic since 1997. He had been bedridden before admission, but could eat. He was admitted with severe aspiration pneumonia in December 1999. Since severe dementia and dysphagia were noted after admission, he was examined to find out whether or not he could swallow while the treatment of his pneumonia was conducted at the same time. The water swallowing test indicated a risk of aspiration, thus, percutaneous endoscopic gastrostomy was performed on January 26, 2000 after the completion of the treatment for pneumonia. Although the patient's condition was complicated by aspiration pneumonia, enteral feeding through the gastric fistula gradually became successful, and he was discharged in June 2000. His family physician followed him up by visiting at home to examine and observe his general physical condition including consciousness, vital signs, skin and respiration, while taking measures in cooperation with the local health care visiting nurse. The patient, thereafter, was repeatedly admitted and discharged because of exacerbation and remission of symptoms, including coughing, sputum and fever, probably caused by aspiration pneumonia. When he was admitted in December 2001, which was his sixth admission, since there were troubles with the infusion tube and frequent gastroesophageal reflux, the gastric fistula management was judged to be a great burden on the patient. In January 2002, the gastrostomy tube was removed and the patients, whose alimentation was managed using intra-venous hyperalimentation (IVH), was discharged. Besides periodic visits by his family physician, a 24-hour house visit system was introduced to control his IVH and deal with his family members' anxiety. His general condition, thereafter, has not markedly changed. The patient has continuously received medical treatment for 14 months after being discharged and his condition is stable.
