Outcome of floppy Nissen fundoplication with intraoperative manometry to treat sliding hiatal hernia

SUMMARY.  The aim of this study was to evaluate the effectiveness of floppy Nissen fundoplication with intraoperative esophageal manometry. Between February 1992 and July 2004, there were 102 patients with sliding hiatal hernia undergoing transabdominal Nissen fundoplication. They were divided into three groups: 27 patients were in the Nissen group (CNF), 44 in the floppy Nissen group (FNF, including 5 with laparoscopic Nissen fundoplication), and 31 in the intraoperative-esophageal-manometry group (INF, 13 with laparoscopic Nissen fundoplication). There were no operation-related deaths. Operation-related complications occurred in five patients within 1 month after operation: In CNF, two patients suffered from dysphagia and one from regurgitation; in FNF, one patient had slight dysphagia and two had regurgitation; in INF, there was no one who complained about dysphagia or regurgitation, but pneumothorax occurred in one case. After more than 2 years of follow-up, two patients, in CNF, suffered from severe dysphagia, one recurred and two with abnormal 24 h pH monitoring. In FNF, one patient had dysphagia, one recurred and three had abnormal 24 h pH monitoring; in INF, two patients had acid reflux on 24 h pH monitoring. The postoperative lower esophageal sphincter pressure was in the normal range in 30 of 31 patients (96.5%). The normal rate of postoperative tests in CNF, FNF and INF were 81.5%, 86.4% and 93.5%, respectively. Both the Nissen fundoplication and the floppy Nissen fundoplication are effective approaches to treat patients with sliding hiatal hernia. Intraoperative manometry is useful in standardizing the tightness of the wrap in floppy Nissen fundoplication and may contribute to reducing or avoiding the occurence of postoperative complications.     

Heller''s esophagomyotomy with or without a 360° floppy Nissen fundoplication for achalasia. Long-term results from a prospective randomized study

Heller's esophagomyotomy relieves dysphagia but does not restore esophageal peristalsis. The myotomy may induce reflux and the addition of a 360 degrees fundoplication may be hazardous with regard to the remaining aperistaltic esophagus. The aim of this prospectively randomized clinical trial was to compare the outcome for patients with uncomplicated achalasia who underwent an anterior Heller's esophagomyotomy (H group) with or without an additional floppy Nissen fundoplication (H + N group). Between 1984 and 1995, 20 patients were prospectively randomized to one or other of the performed operations, 10 patients per group. Esophagitis including Barrett's esophagus (n = 2) was seen under medical treatment, in 6 of 9 in the H group but none in the H + N group. No patient in the H + N group required postoperative continuous acid-reducing drugs. Twenty-four-hour esophageal pH-studies in median 3.4 years after surgery showed pathological reflux expressed as a percentage of time below pH 4 of 13.1% in the H group compared to 0.15% (P < 0.001) in H + N group. One patient with recurrent dysphagia in the H + N group later had an esophagectomy. The remaining patients reported significant improvement of dysphagia without symptoms of reflux at 8.0 years follow-up. Heller's esophagomyotomy eliminates dysphagia, but can induce advanced reflux that requires medical treatment. The addition of a 360 degrees fundoplication eliminates reflux without adding dysphagia in the majority of patients and can be recommended for most patients with uncomplicated achalasia.     

Antireflux surgery for Barrett''s esophagus: comparative results of the Nissen and Collis-Nissen operations

Using a Collis-Nissen repair instead of a standard Nissen fundoplication to treat the reflux disease of Barrett's esophagus is controversial. This paper compares the Nissen and Collis-Nissen operations when treating Barrett's esophagus. Thirty-three patients with documented Barrett's esophagus (male : female, 26 : 7, median age, 48.8 years) had a Nissen fundoplication during 1976-1989. Fifty-one patients (male : female = 41 : 10, median age = 53.2 years) underwent a Collis-Nissen operation between 1990 and 1999. Clinical assessments, esophagogram, radionuclide emptying, manometry, 24-h pH study, and endoscopy were obtained pre- and postoperatively. There was no operative death in either group. Median follow-up was 8.0 years for the Nissen group and 6.5 years for the Collis group. Postoperative reflux symptoms were more frequent in the Nissen group (52%) when compared to the Collis group (7%, P < 0.001). These symptoms correlated with the 24-h pH recordings revealing an increased acid exposure in the Nissen group (3.4%) as opposed to 1% in the Collis group (P = 0.003). Endoscopy revealed mucosal erosions and ulcers in 39% of patients receiving a standard Nissen repair while these damages were seen in 7% of patients who were offered an elongation gastroplasty with a total fundoplication (P = 0.007). The cumulative success rate was 83% for the Nissen group and 100% for the Collis group at 5 years, and 63% versus 90% at 10 years (Log-rank test, P = 0.004). The Collis-Nissen fundoplication provides better reflux protection for Barrett's patients than a standard Nissen repair. It lowers the risk of fundoplication failure.     

Laparoscopic fundoplication in patients with an aperistaltic esophagus and gastroesophageal reflux

A minority of patients with severe gastroesophageal reflux who present to surgeons for antireflux surgery have absent esophageal peristalsis when investigated before surgery with esophageal manometry. Some of these patients also have systemic sclerodema. While conventional wisdom suggests that these patients are at risk of a poor outcome if they proceed to fundoplication, some will have severe reflux symptoms, which are poorly controlled by medical therapy, and surgery will therefore offer the only chance of 'cure'. We performed this study to determine the outcome of laparoscopic fundoplication in the subset of patients with gastroesophageal reflux and an aperistaltic esophagus. From 1991 to 2003, the operative and follow-up details for all 1443 patients who underwent a laparoscopic fundoplication in our Departments have been prospectively collected on a database. These patients were then followed yearly using a standardized symptom assessment questionnaire. A subset of patients whose preoperative esophageal manometry demonstrated complete absence of esophageal body peristalsis and absent lower esophageal sphincter tone (aperistaltic esophagus) were identified from this database, and their outcome following laparoscopic fundoplication was determined. Twenty-six patients with an aperistaltic esophagus who underwent a laparoscopic fundoplication were identified. Six of these had a systemic connective tissue disease (scleroderma), and 20 had an aperistaltic esophagus without a systemic disorder. A Nissen fundoplication was performed in four patients, and an anterior partial fundoplication in 22. Follow-up extended up to 12 years (median, 6). A good overall symptomatic outcome was achieved in 88% at 1 year, 83% at 2 years and 93% at 5-12 years follow-up. Reflux symptoms were well controlled by surgery alone in 79% at 1 year, and 79% at 5-12 years. At 2 years, 87% were eating a normal diet. Two patients underwent further surgery - one at 1 week postoperatively for a tight esophageal hiatus, and one at 1 year for recurrent reflux. Patients with troublesome reflux and an aperistaltic esophagus can be effectively treated by laparoscopic fundoplication. An acceptable outcome will be achieved in the majority of patients.     

Nissen fundoplication in infants and children: a long-term clinical study

BACKGROUND/AIMS: Infants and children who underwent open Nissen fundoplication for gastroesophageal reflux disease were retrospectively evaluated to assess the success and complications of this operation. METHODOLOGY: Twenty-six neurologically normal children (16 boys and 10 girls between 6 months and 11 years old) underwent Nissen fundoplication for intractable or complicated gastroesophageal reflux between October 1982 and February 2002. Before surgery and at follow-up visits, all children were subjected to thorough history, barium meal study and gastroscopy with multiple esophageal biopsies. The median follow-up period was 28 months (range: 11 months-19 years). RESULTS: Persistent vomiting or regurgitation since birth was the main symptom (24 patients, 92.3%), chest symptoms occurred in 5 patients (19.2%), malnutrition and retarded growth were found in 4 patients (15.4%), hematemesis and/or melena occurred in 2 patients (7.7%) and dysphagia due to esophageal stricture occurred in 4 patients (15.4%). There was no mortality. The mean hospital stay was 4.1 days. Twenty-two patients (84.6%) had no recurrent reflux. Reflux symptoms recurred in 4 cases (15.4%). One of these cases had no evidence of recurrent pathological reflux, 2 cases with preoperative stricture developed wrap disruption, recurrent reflux and re-stricture. Both refused a second operation. The fourth case developed melena and reflux esophagitis due to wrap herniation through the hiatus and was successfully managed by a second operation. CONCLUSIONS: Nissen fundoplication is an effective operation to correct gastroesophageal reflux in infants and children when the drug therapy fails. The operation should be done before occurrence of complications to decrease the recurrence of reflux.     

Bile reflux into the esophagus. Bilitec 2000 measurements in normal subjects and in patients after Nissen fundoplication.

BACKGROUND: Bilitec 2000 is a new spectrophotometric system that can detect bilirubin within the esophagus. The aim of this study was to test this new system in vitro and in vivo with special attention to patients operated on laparoscopically for gastroesophageal reflux with Nissen fundoplication. METHODS: In vitro studies of gallbladder bile dilution curves at different pHs were performed with a combined pH and Bilitec probe and by investigation of the drift of the Bilitec system. In vivo studies were performed in 34 normal individuals and 12 patients operated on with a laparoscopic Nissen fundoplication. Intra/intervariations were evaluated in normal individuals. RESULTS: The Bilitec system was able to detect changes in absorbance value within the range 0.14-0.6. Absorbance values were about 30% lower in an acid environment. The percentage of the total time with bile reflux was a median (range) of 3.9 (0-49.6) in normal individuals, with an intravariation within the intervariation, and 8.7 (0-36.6) in patients after a Nissen fundoplication. These values did not differ significantly. Eighty-two per cent of the normal subjects had some degree of bile reflux, if an absorbance value > or = 0.14 was accepted as the threshold value for the presence of bile reflux. CONCLUSIONS: Bile reflux in normal individuals is frequent and not different from that in patients after a Nissen fundoplication. Surprisingly, the latter had bile reflux but no or minimal acid reflux. Factors other than bilirubin may interfere with the measurements.     

Prospective evaluation of 24 hour ambulatory pH metry in Belsey Mark IV antireflux surgery.

This study evaluated the effect of the 270 degrees Belsey Mark IV fundoplication on 24 hour ambulatory pH metry variables. Thirty seven patients with confirmed gastro-oesophageal reflux disease who had a Belsey Mark IV antireflux procedure were evaluated preoperatively and three to six months postoperatively including endoscopy, lower oesophageal sphincter manometry, and 24 hour ambulatory pH metry. In 30 of 37 patients the Belsey Mark IV fundoplication was judged successful based on symptom relief and healing of oesophagitis. In these 30 patients percentage reflux for total, upright, and supine time (median and range) decreased significantly (p < 0.001) from 10.0% (2.7-35.3%), 10.8% (3.2-39.9%), and 6.7 (0.0-33.0%) respectively to 0.5% (0.0-7.4%), 0.6% (0.0-13.7%), and 0.1% (0.0-4.9%) after operation. This decrease in reflux time resulted predominantly from a significant (p < 0.001) reduction in the number of reflux episodes from 98 (23-231) to 14 (0-82) postoperatively. Normalisation of total reflux time (upper limit of normal for time with pH below 4:4%) was found in 89% and normalisation of total and upright and supine reflux in 64% of successfully operated patients with confirmed abnormal acid reflux before operation. A successful antireflux procedure was associated with significant (p < 0.001) increases in lower oesophageal sphincter pressure from 7.8 (0.6) mm Hg to 14.5 (0.7) mm Hg mean (SEM). In seven patients with a failed antireflux operation basal lower oesophageal sphincter pressure did not change significant;y (preoperative value 5.7 (1.3) mm Hg; postoperative value 7.8 (0.8) mm Hg). In these patients reflux time did not decrease after the operation and remained in the abnormal range in all patients. It is concluded that a successful, in contrast with a failed, Belsey Mark IV fundoplication is associated with significant decreases in total, upright, and supine reflux time. Normalisation of pH metry variables is not a prerequisite for successful antireflux surgery. A surgery. A successful 270 degree Belsey Mark IV fundoplication was associated with a significant increase in basal lower oesophageal sphincter pressure, in contrast with the failure group. Restoration of a sufficient lower oesophageal sphincter barrier is an important aim in antireflux surgery.     

Laparoscopic Nissen fundoplication: results and prognostic factors

Introduction: Laparoscopic Nissen fundoplication is the technique of choice in the surgical treatment of gastroesophageal reflux disease. Aims: To review the cases of laparoscopic Nissen fundoplication carried out at our hospital and to analyze the prognostic factors that influenced surgical outcome. Material and methods: A total of 226 patients that underwent laparoscopic Nissen fundoplication within the time frame of 1996 to 2010 were retrospectively reviewed. Surgical results and prognostic factors were evaluated in 182 patients that had a follow-up longer than one year. Results: The Nissen-Rossetti technique was carried out in 219 patients, without short gastric vessel division, and the "floppy"-Nissen technique was performed on seven patients. Intraoperative complication rate was 3.1%, conversion rate was 6.6%, and postoperative complication rate was 4%. Mortality was 0. After surgery, 19% of patients presented with dysphagia that was persistent in only 3.5%. Of the 182 patients with a follow-up longer than one year, 166 (91.2%) were satisfied with the surgical results. In the univariate analysis, esophagitis (OR=0.59) was a protective factor, while a DeMeester score >50 (OR=1.97) and medical treatment resistance (OR=1.75) were risk factors. In the multivariate analysis a DeMeester score >50 (OR=4.24) was the only independent prognostic factor associated with poor outcome. Conclusions: Our results with laparoscopic Nissen fundoplication are comparable to those found in the medical literature, with a high degree of patient satisfaction. Esophagitis is associated with good outcome, while massive reflux and medical treatment resistance are negative prognostic factors.     

Laparoscopic fundoplication for patients with symptoms but no objective evidence of gastroesophageal reflux

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.     

Nonacid reflux in patients with chronic cough on acid-suppressive therapy

BACKGROUND: It is generally accepted that extraesophageal gastroesophageal reflux disease (GERD) symptoms and their persistence despite acid-suppressive therapy are poor prognostic factors for antireflux surgery. Recent studies indicating that cough can be temporally associated with reflux episodes of pH 4 to 7 (ie, nonacid reflux) reinvigorates the need for a more careful workup in patients with cough suspected to be due to GERD. Aim: To evaluate the frequency of chronic cough associated with nonacid reflux and the response of these patients to laparoscopic Nissen fundoplication. METHODS: We retrospectively reviewed data from patients with persistent cough despite twice-daily proton pump inhibitor (PPI) with or without the use of nighttime regimens of histamine-2 receptor antagonist (H2RA), who had undergone combined multichannel intraluminal impedance and pH monitoring. The association of cough and reflux was evaluated by calculating the symptom index (SI) [positive if > or = 50%]. A subset of patients with positive SI values for impedance-detected reflux with therapy was referred for laparoscopic Nissen fundoplication. RESULTS: Of 50 patients (38 female patients; mean age, 43 years; age range, 6 months to 84 years) who were monitored while receiving therapy, 13 patients (26%) had a positive SI for cough. The SI-positive group had a lower percentage of female patients and patients of younger age compared to the SI-negative group. Laparoscopic Nissen fundoplication was performed in six SI-positive patients who became asymptomatic and stopped receiving acid-suppressive therapy during follow-up evaluations (median time, 17 months; range, 12 to 27 months). CONCLUSION: Impedance pH monitoring should be performed while receiving therapy in patients with persistent symptoms who are receiving PPI therapy. A positive SI for nonacid reflux may be helpful in selecting patients who will benefit from antireflux surgery.     

Duodenogastroesophageal reflux: results of medical treatment and antireflux surgery

BACKGROUND/AIMS: Recent studies have shown that reflux of the duodenal content to the esophagus plays an important role in esophageal mucosal damage. The aim of the study is to compare the duodenogastroesophageal (DGER) reflux with the severity of reflux esophagitis and evaluate its response to either medical and/or antireflux surgery. METHODOLOGY: Ninety-six patients with DGER were subjected to thorough history, upper GI endoscopy, barium study, esophageal manometry and 24-hr esophageal pH metry combined with Bilitec 2000. Medical treatment was given for all, while Nissen fundoplication was done for 28 patients. All patients were evaluated after Nissen fundoplication and treatment. RESULTS: The age of studied patients was 36.26+/-12.7 years with male to female ratio 2:1. The chief symptom was heartburn in 73 (76%) patients. Upper GI endoscopy revealed, 30 (31.2%) patients had grade I reflux, 30 (31.2%) patients had grade II reflux, 7 patients had grade III reflux, 5 patients had grade VI reflux, Barrett's esophagus in 14 patients (14.5%), hiatus hernia (HH) in 26 (27%) patients. Barium study revealed that, 40 (41.6%) patients had evidence of reflux, while 34 (35.4%) patients had reflux with HH. Esophageal motility revealed the mean LESP (12.7+/-7.6), 68 patients (70.8%) had normotensive body while ineffective esophageal body motility was encountered in 28 (29.1%) patients. Esophageal 24-hr pH study and Bilitec 2000 revealed that 54 (56.2%) patients had bile reflux with pathological acid reflux, while 42 (43.7%) patients had bile reflux in alkaline pH. Medical treatment gave excellent to good response in 68 (70.8%) patients, while Nissen fundoplication was done for 28 (29.2%) patients. Endoscopic examination 6 months after Nissen fundoplication showed marked improvement in endoscopic injury. Barium study after Nissen fundoplication revealed repair of HH and control of GERD in all patients except one. Esophageal motility, 24 hr pH study and Bilitec 2000, after 6 months of Nissen shows high significant increase in LESP, decrease in acid and bile reflux. No significant difference between open or laparoscopic fundoplication in LESP, acid and bile reflux. CONCLUSIONS: DGER in acid medium is more injurious to the esophagus than DGER in alkaline pH. The severity of esophageal injury does not correlate with the severity of acid or bile reflux but has a direct correlation with impaired distal esophageal motility. Medical treatment gives satisfactory control of symptoms and healing of esophageal lesion in 70% of DGER. The response to medical treatment does not depend on the severity of esophageal injury but depends on the severity of bile and acid reflux. Nissen fundoplication in refractory patients, either open or laparoscopic, was effective in control of heartburn in 95% of patients contrary to 50% in mixed symptoms.     

Fundoplication and the risk of esophageal cancer in gastroesophageal reflux disease: a Veterans Affairs cohort study

BACKGROUND AND AIMS: It has been proposed that fundoplication can reduce the risk of esophageal cancer in patients with gastroesophageal reflux disease (GERD). In this cohort study, we assessed the effect of fundoplication on the incidence of esophageal cancer. METHODS: We identified all Veterans Affairs (VA) patients with GERD who had fundoplication between 1986 and 1990 and matched (1-2) to controls with GERD and no fundoplication and to controls with no GERD. We calculated incidence rates for esophageal cancer through October 2002 and examined the effect of fundoplication on the risk of esophageal cancer using Kaplan-Meier survival analysis and Cox proportional hazard analysis. We calculated and adjusted for the propensity score for receiving fundoplication. RESULTS: We identified 946 patients who had fundoplication, 1,892 patients who had GERD without fundoplication, and 5,676 patients with no GERD. The mean age was 55 yr and 97.5% were men in all three groups. During a follow-up of 11,156 patient-years (PY), there were eight cases of esophageal cancer (72/100,000) in the fundoplication group. During a follow-up of 20,115 PY, there were eight cases of esophageal cancer (40/100,000) in the GERD without fundoplication group. During a follow-up of 59,439 PY, no patients in the group with no GERD developed esophageal cancer. The Kaplan-Meier analysis showed no significant difference in cumulative esophageal cancer rates between the fundoplication group and the GERD no-fundoplication group. The adjusted hazard ratio of esophageal cancer with fundoplication was 1.88 (95% CI: 0.70-5.03). CONCLUSIONS: GERD is a risk factor for esophageal cancer, but there is insufficient evidence that fundoplication reduces that risk.

Revision of failed transoral incisionless fundoplication by subsequent laparoscopic Nissen fundoplication

AIM:To evaluate the feasibility and outcomes of laparoscopic Nissen fundoplication after failed transoral incisionless fundoplication(TIF).METHODS:TIF is a new endoscopic approach for treating gastroesophageal reflux disease(GERD).In cases of TIF failure,subsequent laparoscopic fundoplication may be required.All patients from 2010 to 2013 who had persistence and objective evidence of recurrent GERD after TIF underwent laparoscopic Nissen fundoplication.Primary outcome measures included operative time,blood loss,length of hospital stay and complications encountered.RESULTS:A total of 5 patients underwent revisional laparoscopic Nissen fundoplication(LNF)or gastrojejunostomy for recurrent GERD at a median interval of 24mo(range:16-34 mo)after TIF.Patients had recurrent reflux symptoms at an average of 1 mo following TIF(range:1-9 mo).Average operative time for revisionalsurgical intervention was 127 min(range:65-240 min)and all surgeries were performed with a minimal blood loss(<50 m L).There were no cases of gastric or esophageal perforation.Three patients had additional finding of a significant hiatal hernia that was fixed simultaneously.Median length of hospitalization was 2 d(range:1-3 d).All patients had resolution of symptoms at the last follow up.CONCLUSION:LNF is a feasible and safe option in a patient who has persistent GERD after a TIF.Previous TIF did not result in additional operative morbidity.     

Fate of Nissen fundoplication after 20 years. A clinical, endoscopical, and functional analysis.

Of 46 patients who had Nissen fundoplication for proved gastro-oesophageal reflux, 25 were available for follow up after a median of 20 years, 15 had died of unrelated causes, and six could not be traced. All 25 patients in the follow up study were personally interviewed: 21 consented to an endoscopy, 14 to 24 hour recording of oesophageal pH and manometry, and 15 to radionuclide transit test. Repeat fundoplication for recurrent reflux was performed in two cases during the study. Heartburn and regurgitation were significantly lessened (p < 0.005), but the incidence of dysphagia was slightly increased. Endoscopy showed six of 21 fundic wraps to be defective. Erosive oesophagitis was seen in two patients, and Barrett's oesophagus (histologically confirmed) in one of them and six other patients. Total reflux time was abnormal in four of 14 patients. No patient with an intact fundic wrap seen on endoscopy, only two of seven with Barrett's oesophagus, and one of four with abnormal reflux had oesophagitis. Fundoplication in itself did not affect oesophageal motility or transit, provided that the wrap was intact. It is concluded that Nissen fundoplication gave a reasonably good longterm effect in chronic reflux disease, with the stage of the fundic wrap as the main determinant of outcome.     

Lung transplantation in patients with connective tissue disorders and esophageal dysmotility

SUMMARY. Lung and esophageal dysfunction are common in patients with connective tissue disease (CTD). Recent reports have suggested a link between pathologic gastroesophageal reflux and bronchiolitis obliterans syndrome (BOS) after lung transplant. Because patients with CTD have a high incidence of esophageal dysmotility and reflux, this group may be at increased risk of allograft dysfunction after lung transplantation. Little is known about antireflux surgery in these patients. Our aims were to describe: (i) the esophageal motility and reflux profile of patients with CTD referred for lung transplantation; and (ii) the safety and outcomes of laparoscopic fundoplication in this group. A retrospective review of 26 patients with CTD referred for lung transplantation between July 2003 and June 2007 at a single center. Esophageal studies included manometry and ambulatory 24‐h pH monitoring. Twenty‐three patients had esophageal manometry and ambulatory 24‐h pH monitoring. Nineteen patients (83%) had pathologic distal reflux and 7 (30%) also had pathologic proximal reflux. Eighteen patients (78%) had impaired or absent peristalsis. Eleven of 26 patients underwent lung transplantation. Ten patients are alive at a median follow‐up of 26 months (range 3–45) and one has bronchiolitis obliterans syndrome‐1. Six patients had a laparoscopic fundoplication, 1 before transplantation and 5 after. All fundoplication patients are alive at median follow‐up of 25 months (range 19–45). In conclusion, esophageal dysmotility and reflux are common in CTD patients referred for lung transplant. For this group, laparoscopic fundoplication is safe in experienced hands.     

Prevalence and clinical picture of gastroesophageal prolapse in gastroesophageal reflux disease

The prevalence of gastroesophageal (GE) mucosal prolapse in patients with gastroesophageal reflux disease (GERD) was investigated as well as the clinical profile and treatment outcome of these patients. Of the patients who were referred to our service between 1980 and 2008, those patients who received a complete diagnostic work-up, and were successively treated and followed up at our center with interviews, radiology studies, endoscopy, and, when indicated, esophageal manometry and pH recording were selected. The prevalence of GE prolapse in GERD patients was 13.5% (70/516) (40 males and 30 females with a median age of 48, interquartile range 38-57). All patients had dysphagia and reflux symptoms, and 98% (69/70) had epigastric or retrosternal pain. Belching decreased the intensity or resolved the pain in 70% (49/70) of the cases, gross esophagitis was documented in 90% (63/70) of the cases, and hiatus hernias were observed in 62% (43/70) of the cases. GE prolapse in GERD patients was accompanied by more severe pain (P < 0.05) usually associated with belching, more severe esophagitis, and dysphagia (P < 0.05). A fundoplication was offered to 100% of the patients and was accepted by 56% (39/70) (median follow up 60 months, interquartile range 54-72), which included two Collis-Nissen techniques for true short esophagus. Patients who did not accept surgery were medically treated (median follow up 60 months, interquartile range 21-72). Persistent pain was reported in 98% (30/31) of medical cases, belching was reported in 45% (14/31), and GERD symptoms and esophagitis were reported in 81% (25/31). After surgery, pain was resolved in 98% (38/39) of the operative cases, and 79% (31/39) of them were free of GERD symptoms and esophagitis. GE prolapse has a relatively low prevalence in GERD patients. It is characterized by epigastric or retrosternal pain, and the need to belch to attenuate or resolve the pain. The pain is allegedly a result of the mechanical consequences of prolapse of the gastric mucosa into the esophagus.     

Outcomes of surgical fundoplication in children.

BACKGROUND & AIMS: Surgical fundoplication has been recommended for children with persistent GERD. The purpose of this study was to determine the frequency of postoperative symptoms requiring medical evaluation and/or treatment after fundoplication in children with or without associated medical disorders. METHODS: In a retrospective cohort study, we reviewed the medical records of all children who underwent fundoplication during 1996-1999. Data were collected to analyze the following: (1) postoperative complications, (2) postoperative symptoms, (3) procedures performed to evaluate postoperative symptoms, (4) medical treatment, and (5) repeat surgery. RESULTS: A total of 198 children underwent fundoplication, and 176 (89%) came for follow-up evaluation within 2 months after surgery. The median age at the time of surgery was 2.1 y (range, 6 mo-18 y) and the median duration of follow-up was 2.0 y (range, 1.2-4.8 y). A total of 130 (74%) children had one or more associated medical disorders including neurodevelopmental delay (70%), cystic fibrosis (8%), tracheoesophageal anomalies (8%), bronchopulmonary dysplasia (8%), and reactive airway disease (35%). Postoperatively, children with associated medical disorders had a higher frequency of lung infections (52% vs. 22%, P = .03) and dumping syndrome (2% vs. 0%, P = .05). Most children (63%) received evaluation and treatment for symptoms suggestive of recurrent reflux despite fundoplication. CONCLUSIONS: Nearly two thirds of children who received fundoplication and were followed-up within 2 months after surgery either have symptoms or receive medical therapy for reflux. Fundoplication for the control of GERD in children needs further evaluation.     

Surgical experience improves the long-term results of Nissen fundoplication

BACKGROUND: Nissen fundoplication relieves symptoms of gastro-oesophageal reflux and effectively heals oesophagitis. During long-term follow-up some cases of recurrent reflux are seen. We investigated the possibility that long-term cure of gastro-oesophageal reflux after fundoplication is influenced by the surgeon's experience and focused interest, in line with results of surgery for rectal, gastric, and breast cancer. METHODS: One hundred and five consecutive patients were evaluated a median of 77 months after open Nissen-Rossetti fundoplication for erosive oesophagitis. Follow-up included personal interviews and upper gastrointestinal endoscopy by an investigator not previously involved in the patients' treatment. The surgeons were classified as experienced (>10 of the operations in the series), less experienced (<10 operations), or trainees. RESULTS: Of the most experienced surgeons' patients, 97% had no or at most mild reflux symptoms at follow-up, compared with 88% of the of less experienced surgeons' patients (P = 0.04). Healing of erosive oesophagitis was commoner when the operations were performed by experienced specialist surgeons (88% versus 72%; P = 0.04). The reoperation rate fell as the surgeons' experience increased, from 12% to 4%. CONCLUSIONS: Surgery for gastro-oesophageal reflux should be centralized to units specializing in the techniques and with sufficient annual numbers of operations to optimize results. This policy becomes especially advisable as laparoscopic surgery increases the numbers of treated patients.
