Surgical treatment of gastroesophageal reflux with esophageal stricture in infancy and childhood

During the past 5 years, 26 infants and children with gastroesophageal reflux were operated on. The results have been highly satisfactory and unattended by serious complications or mortality. Barium fluoroscopy was the most reliable diagnostic method. The indications for operation were persistent vomiting with failure to thrive, recurrent aspiration pneumonia, gastrointestinal bleeding and peptic stricture of the esophagus, not relieved by medical treatment. The high incidence of peptic stricture of the esophagus (50 percent) may reflect delay in diagnosis and medical treatment, which is successful in 60 to 87 percent of the infants with gastroesophageal reflux. Surgical treatment consisted of Nissen fundoplication combined with gastrostomy in cases of esophageal stenosis where dilatations were indicated. Complications related to the operation were minimal. In a follow-up period of 9 months to 5 years, all patients had obtained relief of symptoms of reflux and had excellent nutritional status and normal growth.     

Laparoscopic gastroesophageal dissociation in neurologically impaired children with gastroesophageal reflux disease

Purpose

Neurologically impaired children with severe gastroesophageal reflux disease (GERD) are a challenging group of patients. We theorized that a laparoscopic gastroesophageal dissociation (LGED) may decrease reflux-related readmissions and healthcare visits, and improve quality of life (QOL) for them and their caregivers.

The effect of medical therapy and antireflux surgery on dysphagia in patients with gastroesophageal reflux disease without esophageal stricture

BACKGROUND: Poor esophageal body motility and trapping of the hernial sac by the hiatal crura are the major pathomechanisms of gastroesophageal reflux disease (GERD)-induced dysphagia. There is only little knowledge of the effect of medical therapy or antireflux surgery in reflux-induced dysphagia. METHODS: Fifty-nine consecutive GERD patients with dysphagia were studied by means of a symptom questionnaire, endoscopy, barium swallow, esophageal manometry, and 24-hour pH monitoring of the esophagus. Patients had proton pump inhibitor therapy and cisapride for 6 months. After GERD relapsed following withdrawal of medical therapy, 41 patients decided to have antireflux surgery performed. The laparoscopic Nissen fundoplication was chosen in 12 patients with normal esophageal body motility and the laparoscopic Toupet fundoplication in 29 patients with impaired peristalsis. Dysphagia was assessed prior to treatment, at 6 months of medical therapy, and at 6 months after surgery. RESULTS: Heartburn and esophagitis were effectively treated by medical and surgical therapy. Only surgery improved regurgitation. Dysphagia improved in all patients following surgery but only in 16 patients (27.1%) following medical therapy. Esophageal peristalsis was strengthened following antireflux surgery. CONCLUSIONS: Medical therapy fails to control gastroesophageal reflux as it does not inhibit regurgitation. Thus, it has little effect on reflux-induced dysphagia. Surgery controls reflux and improves esophageal peristalsis. This may contribute to its superiority over medical therapy in the treatment of GERD-induced dysphagia.     

Gastric emptying in children with gastroesophageal reflux and in healthy children

Purpose

The aim of this report is to examine whether children with gastroesophageal reflux (GER) have delayed gastric emptying compared to healthy children.

Methods

All patients had GER verified by 24-hour pH monitoring. Gastric emptying of cow’s milk was examined by radionuclide scintigraphy in 51 patients with GER and in 24 controls. Gastric emptying rate was expressed as exponential half time (T_1/2).

Results

Median age was 4.4 years [range 0.1–15.4] in patients and 6.1 years [range 2.5–10.0] in controls (p = .10). A wide range of gastric emptying rates was observed both in GER patients [range 16–121] and controls [range 29–94]. One GER patient (2%) had slower gastric emptying (T_1/2 = 121 min) than the healthy child with the longest T_1/2 (94 min). Mean T_1/2 was 49 minutes (SD 20.1) and 46 minutes (SD 14.2) in GER patients and controls, respectively (p = .51).

Conclusions

Gastric emptying rate of milk was not significantly different between children with GER and healthy children. A wide range of gastric emptying rates was observed in both groups.     

Management of gastroesophageal reflux associated with malrotation in children

Aim

Children being investigated for gastroesophageal reflux (GOR) have a high incidence of malrotation. Current literature suggests these patients should be managed with a combined antireflux and Ladd's procedure. We review our experience, the largest series to date, of performing an elective Ladd's procedure as the first-line intervention.

Method

Retrospective case note review of 20 children with significant symptoms of GOR and an incidental finding of malrotation. Children presenting immediately with bilious vomiting were excluded. All patients underwent a Ladd's procedure as their sole primary operative intervention.

Results

Median age at operation was 7 months (21 days-12 years). Fifteen patients (75%) had evidence of reflux on barium contrast study. All children were followed up for at least 6 months. Eighteen (90%) had resolution or significant improvement of their symptoms postsurgery. Only 3 have not managed to tolerate a full oral diet, all unrelated to GOR. None of our series required an antireflux procedure.

Conclusion

In children with debilitating vomiting necessitating surgical management, a contrast study is imperative in the work up. The high incidence of GOR and the significant improvement after correction of malrotation show the relationship between delayed gastric emptying and GOR. We suggest that when an abnormally placed duodenojejunal flexure is found, a Ladd's procedure alone is sufficient and may obviate the need for a more invasive antireflux procedure.     

Alkaline gastroesophageal reflux in infants and children

The incidence of alkaline gastroesophageal reflux (GER) was examined in 111 consecutive children referred for evaluation of GER during a 1-year period. The results of 24-hour pH monitoring studies and the medical records were retrospectively evaluated. Acid reflux was defined as occurring whenever the pH was less than 4 and alkaline reflux was defined whenever the pH was greater than 7. The percentage of time that reflux occurred, the number of reflux episodes, the number of episodes greater than 5 minutes, and the longest episode were all recorded. Based on these data, four categories of patients were identified as compared with normal values as determined by Pellegrini et al. When using criteria based on the percentage of time that reflux occurred, the largest group of children with GER was found to reflux acid (50%). However, 27 children (24%) had combined acid and alkaline reflux. Eighteen (16%) had predominantly alkaline reflux. Previously, these 18 children would have been considered as having a low likelihood of reflux by pH criteria. Endoscopic examination showed that pathological evidence of esophagitis occurred in four of the children with pure alkaline reflux. This review shows that symptomatic GER in infants and children may be due to acid or alkaline secretions or a mixture of both. A previously unrecognized cohort exists of children who demonstrate primary alkaline reflux. These patients need to be recognized and may benefit from a therapeutic program specifically designed to control alkaline reflux.     

Management of severe gastroesophageal reflux in children

To evaluate response to fundoplication, clinical results for 66 consecutive pediatric patients operated on for gastroesophageal reflux were retrospectively reviewed. Indications for operation were gastroesophageal reflux with apnea, repeated emesis, recurrent pneumonia, failure to thrive, stricture, and esophagitis. All patients had preoperative documentation of significant gastroesophageal reflux by either cinefluoroscopic reflux esophagogram or reflux nuclear scan. Fundoplication was effective in 56 (87%) of 64 patients. None of the patients considered to be operative failures had persistent gastroesophageal reflux. Operative failures occurred primarily in patients with gastroesophageal reflux and apnea or recurrent pneumonia. More advanced diagnostic tests, such as pH monitoring, may help to select patients whose symptoms of apnea and recurrent pneumonia are truly due to reflux. Gastroesophageal reflux produces significant morbidity in pediatric patients and is well treated operatively by fundoplication.     

Laparoscopic treatment for gastroesophageal reflux in children

Since 1998 we have operated 5 patients with gastroesophageal reflux (GER) by laparoscopic procedure, aged between 6 and 16 years. In the 3 smaller patients we have done the Boix-Ochoa antireflux technique. In the other 2 patients we have done the Nissen fundoplicature. At 3 months of postoperative course, the 24 hours-pHmetry is normal in all the patients. They also refer the absence of symptomatology of vomiting and/or pyrosis. In 3 patients we could do a postoperative manometry of the distal esophagic sphincter, with normal values. The postoperative dysphagia of the first seems to be lesser in the group treated with the Boix-Ochoa technique.     

Redo fundoplication in infants and children with recurrent gastroesophageal reflux

The Nissen fundoplication is well established as the surgical treatment for medically refractory gastroesophageal reflux (GER) in childhood. Recurrent GER following fundoplication is a challenging problem with a reported incidence ranging from 0% to 12%. From January 1974 to January 1989, 286 children have been treated for GER with Nissen fundoplication and gastrostomy tube placement at the University of Michigan C.S. Mott Children's Hospital; 242 of these children have been followed for an average of 30 months, the remaining 44 have been lost to follow-up. Twenty-nine children (12%) have developed recurrent reflux following fundoplication. Medical management with thickened upright feelings, gastrostomy feedings, or gastrojejunostomy tube feedings has been successful for 11 children with control of reflux symptoms. Five additional children who were treated nonoperatively died of coexistant medical problems within 2 months following documentation or recurrent reflux. The remaining 13 children have required redo fundoplication for wrap disruption or herniation, and an additional six children, initially treated at other institutions, have also undergone redo fundoplications. One other child treated at this hospital required redo fundoplication for a postoperative partial gastric volvulus causing gastric outlet obstruction. Of the 20 children who have undergone a second Nissen fundoplication, 16 (80%) are doing well without recurrent GER. Four children have developed recurrent GER with wrap disruption; 1 is doing well following a third fundoplication, 2 have been managed successfully with continuous feedings via gastrojejunostomy feeding tubes, and a fourth child died of complications related to a recurrent tracheoesophageal fistula. Conservative management with gastrojejunal tube feedings should be considered in the initial management of children with recurrent GER following fundoplication.(ABSTRACT TRUNCATED AT 250 WORDS)     

Surgery for gastroesophageal reflux in children with normal pH studies

Esophageal pH monitoring is recognized as the best diagnostic procedure for gastroesophageal reflux (GER) and operation is seldom recommended in the absence of abnormal pH data. To emphasize that operation should not be ruled out for children who may have false-negative pH studies, we report 14 patients operated on for GER in spite of normal pH-monitoring. The mean age was 54 months (range, 18 to 90). Clinical features included vomiting, dysphagia, respiratory disease, anemia, and torticollis. All had radiologic evidence of GER, and 10 had endoscopic and histological esophagitis. Conventional pH-monitoring values were normal but lower esophageal sphincter pressure and propulsive peristalsis were significantly decreased whereas nonpropulsive contractions were predominant. Operation was recommended after an average of 24 months of unsuccessful medical treatment. Independent postoperative assessment showed that 13 of the 14 patients were relieved of their symptoms and dysphagia persists in one. We suggest that the diagnosis of GER should be accepted on the basis of sound clinical judgement plus more than one abnormal test even when pH results are normal. Operation should not be withheld when clinically indicated. There are several explanations for false-negative pH studies, of which alkaline reflux is probably the most important and warrants further investigation in children.     

Fundoplication as treatment for gastroesophageal reflux in children

Esophageal stricture resulting from gastroesophageal reflux is common among children in Ecuador. The sequence of events is vomiting, recurrent pneumonia, failure to thrive and stricture with resulting malnutrition. The diagnosis is confirmed by barium meal and esophagoscopy. The age of the affected population ranges from one month to 12 years. In the past, surgical treatment included esophageal replacement but the most appropriate current treatment is Nissen fundoplication to restore the gastroesophageal sphincter function.     

Jejunal interposition for recurrent gastroesophageal reflux in children

There is limited experience with surgical treatment for recurrent gastroesophageal reflux after an antireflux procedure. In four pediatric patients with recurrent reflux after surgical therapy, interposition of an isoperistaltic segment of jejunum produced excellent short-term results. Further follow-up is needed as experience broadens. At the present time, this procedure merits consideration in patients with recurrent gastroesophageal reflux.
