Long-term outcome is worse after laparoscopic than after conventional Nissen fundoplication

Objective. No long-term studies of laparoscopic and open fundoplication were available in 1994. The aim of this study was to compare reflux control and side effects after laparoscopic and open fundoplication. Material and methods. Adult patients with uncomplicated gastro-oesophageal reflux disease were included in this prospective randomized clinical trial between laparoscopic and open 360° fundoplication. Patients with uncomplicated gastro-oesophageal reflux disease were included with the exception of those with weak peristalsis or suspected short oesophagus. Two senior surgeons, well trained in laparoscopic antireflux surgery, performed the 45 laparoscopic operations. Forty-eight patients underwent open surgery performed or supervised by two other senior surgeons, also well trained in gastro-oesophageal surgery. One of the latter recruited all the patients. Manometry and 24-h oesophageal pH monitoring were performed before operation and 6 months postoperatively. Manometry also included a short-term reflux test, an acid clearing test and an acid perfusion test. Symptom evaluation was performed before surgery, 6 moths after and at long-term follow-up (33–79 months postoperatively) by the same surgeon. Long-term follow-up also included endoscopy. Results. Six months after laparoscopy 4 patients had disabling dysphagia. None of the patient had disabling dysphagia after laparotomy. Four patients had mild heartburn 6 months after laparoscopy and 2 patients after laparotomy. Between 6 months’ follow-up and long-term follow-up, 6 patients were reoperated on in the laparoscopy group and 2 patients in the laparotomy group. Three patients operated on with laparotomy had died of intercurrent diseases. After laparoscopy, at long-term follow-up, 62% of patients (28/45) were satisfied compared with 91% (41/45) after laparotomy. The difference was significant (p<0.01). Conclusions. Early postoperative reflux control was similar for laparoscopic and conventional fundoplication. At long-term follow-up significantly more patients were satisfied after laparotomy than after laparoscopy.     

Transoral incisionless fundoplication for gastro-esophageal reflux disease: Techniques and outcomes

Gastro-esophageal reflux disease(GERD)is a verycommon disorder that results primarily from the loss of an effective antireflux barrier,which forms a mechanical obstacle to the retrograde movement of gastric content.GERD can be currently treated by medical therapy,surgical or endoscopic transoral intervention.Medical therapy is the most common approach,though concerns have been increasingly raised in recent years about the potential side effects of continuous longterm medication,drug intolerance or unresponsiveness,and the need for high dosages for long periods to treat symptoms or prevent recurrences.Surgery too may in some cases have consequences such as longlasting dysphagia,flatulence,inability to belch or vomit,diarrhea,or functional dyspepsia related to delayed gastric emptying.In the last few years,transoral incisionless fundoplication(TIF)has proved an effective and promising therapeutic option as an alternative to medical and surgical therapy.This review describes the steps of the TIF technique,using the Esophy X#174;device and the MUSETM system.Complications and their management are described in detail,and the recent literature regarding the outcomes is reviewed.TIF reconfigures the tissue to obtain a full-thickness gastroesophageal valve from inside the stomach,by serosato-serosa plications which include the muscle layers.To date the procedure has achieved lasting improvement of GERD symptoms(up to six years),cessation or reduction of proton pump inhibitor medication in about 75%of patients,and improvement of functional findings,measured by either p H or impedance monitoring.     

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.     

Gastroesophageal reflux disease in children: efficacy of Nissen fundoplication in treating digestive and respiratory symptoms. Experience of a single center

Fundoplication has been commonly performed in neurologically impaired and normal children with complicated gastroesophageal reflux disease. The relationship between gastroesophageal reflux disease and respiratory diseases is still unclear. We aimed to compare results of open and laparoscopic procedures, as well as the impact of fundoplication over digestive and respiratory symptoms. From January 2000 to June 2007, 151 children underwent Nissen fundoplication. Data were prospectively collected regarding age at surgery, presence of neurologic handicap, symptoms related to reflux (digestive or respiratory, including recurrent lung infections and reactive airways disease), surgical approach, concomitant procedures, complications, and results. Mean age was 6 years and 9 months. Eighty‐two children (54.3%) had neurological handicaps. The surgical approach was laparoscopy in 118 cases and laparotomy in 33. Dysphagia occurred in 23 patients submitted to laparoscopic and none to open procedure (P = 0.01). A total of 86.6% of patients with digestive symptoms had complete resolution or significant improvement of the problems after the surgery. A total of 62.2% of children with recurrent lung infections showed any reduction in the frequency of pneumonias. Only 45.2% of patients with reactive airway disease had any relief from bronchospasm episodes after fundoplication. The comparisons demonstrated that Nissen fundoplication was more effective for the resolution of digestive symptoms than to respiratory manifestations (P = 0.04). Open or laparoscopic fundoplication are safe procedures with acceptable complication indices and the results of the surgery are better for digestive than for respiratory symptoms.

Laparoscopic fundoplication versus lansoprazole for gastro-oesophageal reflux disease. A pH-metric comparison

BACKGROUND: Treatment strategies that abolish abnormal reflux could prevent long-term complications of gastro-oesophageal reflux disease. AIMS: To compare the efficacy of laparoscopic fundoplication and lansoprazole in abolishing abnormal reflux in patients with gastro-oesophageal reflux disease. PATIENTS: Study population comprised 130 patients referred for possible antireflux surgery and with heartburn as the dominant symptom. METHODS: After oesophageal manometric and pH-metric evaluation and detailed information 55 patients asked to undergo laparoscopic antireflux surgery while 75 chose a medical treatment regimen based on lansoprazole. Treatment efficacy was assessed by ambulatory oesophageal pH-monitoring. RESULTS: All 55 patients who underwent fundoplication became free of heartburn: oesophageal pH-monitoring gave normal results in 85%. In patients treated with lansoprazole, at individualized daily dosages titrated to abolish both heartburn and abnormal acid reflux, normal pH-metric results were obtained in 96% of cases (p<0.05 vs surgically treated patients). CONCLUSIONS: Lansoprazole at individualized dosages was significantly more effective than laparoscopic fundoplication, in the short-term, in abolishing abnormal reflux in gastro-oesophageal reflux disease patients.     

Influence of esophagealmotility on the outcome of laparoscopic total fundoplication

SUMMARY.   The aim of this study is to evaluate if esophageal dysmotility can influence the outcome of laparoscopic total fundoplication for gatro-esophageal reflux disease (GERD). The advent of laparoscopic fundoplication has greatly reduced the morbidity of antireflux surgery and by now, it should be considered the surgical treatment of choice for GERD. Some authors assert that total versus partial fundoplication should improve the rate of postoperative dysphagia or gas bloat syndrome, particularly in patients with esophageal dysmotility. From September 1992 to December 2005, 420 consecutive patients 171 male and 249 female, mean age 42.8 years (range 12–80) underwent laparoscopic Nissen-Rossetti fundoplication. At manometric evaluation, we divided patients into two groups: group A (163/420; 38.8%) with impaired esophageal peristalsis (peristaltic waves with a pressure < 30 mmHg), and group B (257/420; 61.2%) without impaired peristalsis. We followed up clinically 406 out of 420 (96.7%) patients, 156/163 patients (95.7%) in group A and 250/257 patients (97.3%) in group B. An excellent outcome was observed in 143/156 (91.7%) group A patients and in 234/250 (93.6%) group B patients ( P  = NS). Both groups showed significant improvement in clinical symptom score with no statistically significant difference between patients with normal and impaired peristalsis. Thus, preoperative defective esophageal peristalsis is not a contraindication to total laparoscopic fundoplication.     

Is patient satisfaction sufficient to validate endoscopic anti-reflux treatments?

Endoscopic anti-reflux treatment is emerging as a new option for gastro-esophageal reflux disease (GERD) treatment in patients with the same indications as for laparoscopic fundoplication. There are many techniques, the first of which are transoral incisionless fundoplication (TIF) and nonablative radio-frequency (STRETTA) that have been tested with comparative studies and randomized controlled trials, whereas the other more recent ones still require a deeper evaluation. The purpose of the latter is to verify whether reflux is abolished or significantly reduced after intervention, whether there is a valid high pressure zone at the gastroesophageal junction, and whether esophagitis, when present, has disappeared. Unfortunately in a certain number of cases, and especially in the more recently introduced ones, the evaluation has been based almost exclusively on subjective criteria, such as improvement in the quality of life, remission of heartburn and regurgitation, and reduction or suspension of antacid and antisecretory drug consumption. However, with the most studied techniques such as TIF and STRETTA, an improvement in symptoms better than that of laparoscopic fundoplication can often be observed, whereas the number of acid episodes and acid exposure time are similar or higher, as if the acid refluxes are better tolerated by these patients. The suspicion of a local hyposensitivity taking place after anti-reflux endoscopic intervention seems confirmed by a Bernstein test at least for STRETTA. This examination should be done for all the other techniques, both old and new, to identify the ones that reassure rather than cure. In conclusion, the evaluation of the effectiveness of the endoscopic anti-reflux techniques should not be based exclusively on subjective criteria, but should also be confirmed by objective examinations, because there might be a gap between the improvement in symptoms declared by the patient and the underlying pathophysiologic alterations of GERD.     

Does combined multichannel intraluminal esophageal impedance and manometry predict postoperative dysphagia after laparoscopic Nissen fundoplication?

Laparoscopic Nissen fundoplication (LNF) is an effective treatment for gastroesophageal reflux disease; however, some patients develop dysphagia postoperatively. Manometry is used to evaluate disorders of peristalsis, but has not been proven useful to identify which patients may be at risk for postoperative dysphagia. Multichannel intraluminal impedance (MII) evaluates the effective clearance of a swallowed bolus through the esophagus. We hypothesized that MII combined with manometry may detect those patients most at risk of developing dysphagia after LNF. Between March 2003 and January 2007, 74 patients who agreed to participate in this study were prospectively enrolled. All patients completed a preoperative symptom questionnaire, MII/manometry, and 24‐h pH monitoring. All patients underwent LNF. Symptom questionnaires were administered postoperatively at a median of 18 months (range: 6–46 months), and we defined dysphagia (both preoperatively and postoperatively) as occurring more than once a month with a severity ≥4 (0–10 Symptom Severity Index). Thirty‐two patients (43%) reported preoperative dysphagia, but there was no significant difference in pH monitoring, lower esophageal sphincter pressure/relaxation, peristalsis, liquid or viscous bolus transit (MII), or bolus transit time (MII) between patients with and without preoperative dysphagia. In those patients reporting preoperative dysphagia, the severity of dysphagia improved significantly from 6.8 ± 2 to 2.6 ± 3.4 (P < 0.001) after LNF. Thirteen (17%) patients reported dysphagia postoperatively, 10 of whom (75%) reported some degree of preoperative dysphagia. The presence of postoperative dysphagia was significantly more common in patients with preoperative dysphagia (P= 0.01). Patients with postoperative dysphagia had similar lower esophageal sphincter pressure and relaxation, peristalsis, and esophageal clearance to those without dysphagia. Neither MII nor manometry predicts dysphagia in patients with gastroesophageal reflux disease or its occurrence after LNF. The presence of dysphagia preoperatively is the only predictor of dysphagia after LNF.     

Results of laparoscopic reoperation for failed antireflux surgery: does the indication for redo surgery affect the outcome?

Short and medium term outcomes from laparoscopic antireflux surgery are generally excellent. A small number of patients suffer recurrent reflux or intolerable side-effects and may require reoperation. In this paper we describe our experience of 35 laparoscopic reoperations from a single center. Data on patients undergoing antireflux surgery in our unit has been prospectively collected and includes more than 600 primary laparoscopic antireflux operations since 1993. Laparoscopic reoperations have been performed between 1996 and 2005 for patients suffering recurrent reflux, dysphagia or severe gas bloat symptomatic despite medical treatment. All patients underwent preoperative barium studies and endoscopy with selective manometry and pH studies. Symptomatic outcomes were evaluated at 6 weeks and 12 months with Visick scores. Anatomical results were assessed with barium studies at between 6 and 12 months. Thirty-five laparoscopic reoperations were performed in 20 women and 13 men (median age 56 years). Primary surgery had been performed in our unit in 27 (77%) and elsewhere in eight (23%). Median time from primary surgery was 28.5 months (5-360). Two patients underwent a second reoperation. Indication was recurrent reflux in 28 (80%), dysphagia in five (14%) and gas bloat in two (6%). Thirty-two of the 35 reoperations (91.4%) were completed laparoscopically, median operating time was 120.5 min (65-210) and median hospital stay 2 days. There was no mortality and there were only five minor complications. Twelve-month follow-up was available for 32 reoperations (91%). Overall good symptomatic outcomes were obtained in 26 (74%) Visick I or II at 6 weeks and 24 of 32 (75%) at 12 months. In reoperations for dysphagia/gas bloat there was a relative risk of 4.26 of a poor symptomatic outcome (Visick III or IV) at 12 months compared to those for recurrent reflux (P < 0.05, Fisher's exact test). Laparoscopic reoperation is feasible with low conversion rates and minimal morbidity for patients who have undergone previous abdominal or thoracic hiatal repair. Symptomatic outcomes are generally good, particularly if the indication is recurrent reflux.     

Esophageal dysmotility and other preoperative factors associated with acid suppressive therapy after fundoplication

Abstract

Background and aims: Acid suppressive therapy (AST) is frequently used after fundoplication. Prior studies show that most patients requiring AST after fundoplication have normal esophageal acid exposure and therefore do not need AST. Our aim was to determine the indications for AST use following fundoplication and the associated factors.

Methods: Retrospective analysis of patients who underwent fundoplication at our institution between 2006 and 2013 with pre and postoperative esophageal physiologic studies was performed. Demographic data, symptoms, and findings on high resolution manometry, esophageal pH monitoring and upper endoscopy were collected.

Results: Three hundred and thirty-nine patients were included with a median follow up time of 12.8[2.6, 47.7] months. Mean age was 59.6?±?13.3?years and 71.4% were women. Of those, 39.5% went on AST following fundoplication with a median time to AST use of 15.7[2.8, 36.1] months. The most common reason for AST use was heartburn. Only 29% of patients had objective evidence of acid reflux. Preoperative factors associated with AST use following fundoplication were male gender (HR1.6, p?=?0.019), esophageal dysmotility (HR1.7, p?=?0.004), proton pump inhibitor use (HR2.3, p?<?0.001) and prior history of fundoplication (HR1.8, p?=?0.006). In those with paraesophageal hernia repair with Collis gastroplasty (N?=?182), esophageal dysmotility (HR1.7, p?=?0.047) and NSAID use (HR1.9, p?=?0.023) were associated with AST use postoperatively.

Discussion: AST use is common after fundoplication. Male gender, preoperative esophageal dysmotility, proton pump inhibitor use and redo fundoplication were associated with AST use following fundoplication. In those undergoing combined Collis gastroplasty, preoperative NSAID use and esophageal dysmotility predicted AST use.     

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.     

Laryngopharyngeal Reflux Disease Treated with Laparoscopic Fundoplication

The objective of this clinical prospective study was to find out if laparoscopic Nissen fundoplication is an effective treatment in laryngopharyngeal reflux disease. Twenty-two consecutive patients, 16 female and 6 male, who were referred to laparoscopic fundoplication and operated by a senior gastroenterology surgeon were included in this study. Their mean age was 41 years (SD 13), and ranged from 18 to 64. The patients selected for surgical treatment had LPRD with several vocal and laryngeal symptoms. The status findings were typical for laryngopharyngeal reflux and the symptoms and signs had responded to antireflux medication. Vocal symptoms were interviewed and patients underwent laryngoscopy, esophagogastroscopy, and 24-h esophageal pH monitoring. The follow-up of symptoms and signs were 3 months after beginning of medication, before surgery, 3 months, and 1 year after surgery. The number of patients experiencing vocal symptoms decreased during the medical treatment, from the situation before medical treatment to the situation before surgery (P < 0.001), from the situation before surgery to the situation 3 months (P < 0.001) and 1 year post operation (P < 0.001), but no significant changes were found from the situation 3 months to 1 year post operation. Voice quality improved significantly only from the time point before surgery to 3 months post operation. Three months after medical treatment, laryngeal and pharyngeal findings did not decrease significantly, but several findings decreased significantly (P < 0.001) from the time point before surgery compared to 3 months and to 1 year post operation. Based on this study, the laparoscopic fundoplication is an effective and safe treatment of LPRD.     

Narrative review of management controversies for paraesophageal hernia

ObjectiveTo review management controversies in paraesophageal hernia and options for surgical repair.BackgroundParaesophageal hernia is an increasingly common problem. There are controversies over whether and when paraesophageal hernias should be surgically repaired. In addition, if these hernias are to be repaired, the method of repair, need for mesh reinforcement, need for fundoplication, and need for gastropexy are not uniformly accepted.MethodsRecent literature was reviewed on need for repair, approach (open, laparoscopic or robotic surgery), method of repair (primary suture, use of relaxing incisions, use of mesh reinforcement), materials and configuration of mesh reinforcement, need and type of fundoplication, and need for gastropexy, with emphasis on surgical outcomes.ConclusionsThe extant literature suggests that paraesophageal hernia should be approached in a patient-centered, precision medicine manner. In general, hernia reduction, sac excision and primary suture approximation of the hiatal crura are mandatory. Use of mesh should be based on individual risk factors; if mesh is used, biological meshes appear to have a more favorable safety profile, with the “reverse C” or keyhole configuration allowing for increase in crural tensile strength at it most vulnerable areas. Use and choice of fundoplication or magnetic sphincter augmentation should be based on individual considerations. Finally, gastropexy is generally ineffective and should be used only in extreme circumstances.     

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.     

Influence of psychopathological changes on quality of life after laparoscopic fundoplication for the treatment of gastroesophageal reflux

There are references in medical literature to the influence of psychopathological changes and their negative impact on the results of laparoscopic fundoplication. The objective of this study is to analyze the influence of psychological changes, as assessed by the General Health Questionnaire-28 (GHQ-28), on patients undergoing surgery for gastroesophageal reflux.
This is a prospective study in a series of 103 consecutive patients (62 males and 41 females with a mean age of 40 years) undergoing laparoscopic fundoplication. In addition to functional studies, patients completed the SF-36, Gastrointestinal Quality of Life Index, and GHQ-28 before surgery. Functional tests and questionnaires were repeated 6 months after surgery. Patients were also questioned about their degree of satisfaction. Postoperative results of patients with a normal GHQ-28 and patients showing psychopathological changes as defined by the GHQ-28 questionnaire before surgery were compared.
Overall, all patients experienced an improvement in their quality of life. Forty-one patients showed a pathological result in the preoperative GHQ-28 questionnaire. No differences were found in functional results and degree of satisfaction with surgery between patients with normal and pathological results in the preoperative GHQ-28 questionnaire. However, patients with a pathological result in the preoperative GHQ-28 had poorer results in all domains of the postoperative Gastrointestinal Quality of Life Index and SF36 quality of life questionnaires as compared to patients with a normal preoperative GHQ-28 questionnaire.
Patients with pathological results in the preoperative GHQ-28 had poorer results in terms of postoperative quality of life despite having normal postoperative physiological studies; this decreased quality of life did not have an impact on the degree of satisfaction with surgery performed. The GHQ-28 does not therefore appear to serve as a predictor of postoperative satisfaction.     

Symptoms experienced during 24-h pH monitoring and their relationship to outcome after laparoscopic total fundoplication

SUMMARY.  Some patients having a 24-h pH monitoring test prior to laparoscopic fundoplication experience no symptoms at all in spite of having a positive test, and other patients experience only atypical symptoms in spite of having a positive test. This study investigates the postoperative outcome of such patients. All patients underwent esophageal manometry and 24-h esophageal pH monitoring before laparoscopic total fundoplication. Patients were divided into three groups based on their symptom profile recorded during a positive 24-h pH monitoring: those with typical symptoms ( n = 104), those with atypical symptoms ( n = 28) and those who experienced no symptoms at all ( n = 23). The outcomes measured were heartburn score (0–10), dysphagia composite score (0–45) and satisfaction score (0–10) at 12 months after surgery. Outcome analysis reveals the heartburn scores were significantly reduced postoperatively for all groups of patients. At 1 year after surgery, there was no difference among the three groups of patients in terms of heartburn score and dysphagia composite scores, nor the experience of bloating, belching, or their willingness to repeat surgery. Despite one group experiencing no symptoms, and another group atypical symptoms during a positive pH study, the postoperative satisfaction scores for these two groups was good, but significantly less ( P = 0.03, P = 0.02, respectively) than the group of patients with a typical symptom index. In conclusion, patients who experience only atypical symptoms or no symptoms at all during their preoperative positive 24-h pH monitoring may still obtain a good result from antireflux surgery. However, these symptom profiles should alert the surgeon that such patients may have an outcome which is not as good as patients who experience only typical symptoms during a pH study.     

Fundoplication for gastroesophageal reflux disease: regional variability and factors predicting operative approach

We have recently shown that the majority of patients undergoing fundoplication in the United States are women. Based on these findings, we hypothesized that nonbiological factors contribute to the decisions on surgical reflux therapy. Using State Inpatient Databases of the Agency for Healthcare Research and Quality, we extracted annual fundoplication rates, sex distribution, age cohorts, racial background, and insurance coverage. To account for potential differences in state populations, the results were normalized and correlated with Census data, adult obesity rates, median income, poverty rates, and physician workforce within the state. Fundoplication rates varied fivefold between states, ranging from 4.1 ± 0.1 per 100 000 in New Jersey to 21.8 ± 0.4 per 100 000 in Oregon. Higher poverty rates and a higher fraction of Caucasians within a state independently predicted higher fundoplication rates. While the majority of operations were performed laparoscopically, surgical approaches also differed between states with rates of laparoscopic ranging from 52.3 ± 1.8% in Oklahoma to 87.4 ± 1.7% in Hawaii. A lower number of pediatric and Medicaid‐insured patient and a higher fraction of privately insured patients best predicted higher rates of laparoscopic surgery. Our study shows significant regional variation in surgical reflux management, which cannot be explained by differences in disease mechanisms. Insurance coverage and racial background influenced the likelihood of surgery, suggesting a role of financial incentives.
