Upright,supine, or bipositional reflux

INTRODUCTION: This study was undertaken to determine if the body position in which gastroesophageal reflux occurs before fundoplication--i.e., pattern of reflux--affects symptoms before or after laparoscopic Nissen fundoplication. METHODS: A total of 417 patients with gastroesophageal reflux disease (GERD) underwent pH studies, and the severity of reflux in the upright and supine positions was determined. The percent time with pH less than 4 was used to assign patients to one of four groups: upright reflux (pH < 4 more than 8.3% of time in upright position, n = 80), supine reflux (pH < 4 more than 3.5% of time in supine position, n = 73), bipositional reflux (both supine and upright reflux, n = 163), or neither (n = 101). Before and after laparoscopic Nissen fundoplication, the frequency and severity of symptoms of reflux (e.g., dysphagia, regurgitation, choking, heartburn, chest pain) were scored on a Likert scale (0 = never/not bothersome to 10 = always/very bothersome). For each patient, symptom scores before versus after fundoplication were compared using the Wilcoxon matched pairs test; comparisons of symptom scores among patients grouped by reflux patterns were made using Kruskal-Wallis test. RESULTS: Before fundoplication, the patterns of reflux did not affect the frequency or severity of reflux symptoms. After laparoscopic fundoplication, all symptoms of bipositional reflux improved, and essentially all symptoms of isolated supine or upright reflux or neither improved. CONCLUSIONS: Preoperatively, regardless of the patterns of reflux, symptoms among patients were similar. After fundoplication, symptoms of GERD improved for all patterns of reflux. Laparoscopic fundoplication imparts dramatic and broad relief of symptoms of GERD, regardless of the patterns of reflux. Application of laparoscopic Nissen fundoplication is encouraged.     

Gastroesophageal reflux disease (GERD) and chest pain

Background

Laparoscopic fundoplication cures heart-burn and regurgitation in patients with gastroesophageal reflux disease (GERD) but its effect on the chest pain that is also experienced by some patients is less clear. Confusion stems from the fact that it is difficult to determine preoperatively whether the chest pain is actually caused by the reflux. Therefore, we designed a study in patients with GERD and chest pain that would assess the value of pH monitoring in establishing a correlation between the symptom and the disease, the predictive value of pH monitoring on the results of surgical treatment, and the outcome of laparoscopic fundoplication on chest pain in patients with GERD.

Methods

Of 487 patients who underwent laparoscopic fundoplication for GERD at our institution between October 1992 and July 2000, 165 (34%) complained of chest pain in addition to heartburn and regurgitation. Their symptoms had been present for an average of 118 months. The pH monitoring tracings were analyzed for a correlation between episodes of reflux and chest pain. The mean length of follow-up was 13 months.

Results

Among the 165 patients with chest pain, the relationship between pain and reflux during pH monitoring was as follows: 39 patients (group A) experienced no chest pain during the study; in 28 patients (group B), chest pain correlated with reflux in ≥40% of instances; in 98 patients (group C), chest pain correlated with reflux in ≥40% of instances. Chest pain improved post-operatively in 65% of group A patients, 79% of group B patients, and 96% of group C patients (group C vs A and B: p<0.05). Heartburn and regurgitation resolved or improved in 97% and 95% of patients, respectively.

Conclusions

These data show that pH monitoring helped to identify a relationship between chest pain and reflux; and when the two coincided, the chest pain was relieved by antireflux surgery.

     

Symptomatic and physiologic outcomes after operative treatment for extraesophageal reflux

Background: Pharyngeal pH monitoring has recently been used to identify patients with extraesophageal symptoms induced by gastroesophageal reflux. We employed this method of acid detection to evaluate patients with respiratory symptoms prior to and after laparoscopic Nissen fundoplication to further elucidate the relationship between GERD and respiratory symptoms. Methods: Twenty-one consecutive patients with extraesophageal symptoms thought to be caused by reflux underwent symptomatic and functional evaluation (esophageal manometry and 24-h pH monitoring with a pharyngeal probe) before and after laparoscopic Nissen fundoplication. Episodes of pharyngeal acid exposure were considered abnormal if the pH dropped below 4, occurred simultaneously with esophageal acidification, and occurred outside meal times. Results: All patients had gastroesophageal reflux disease (GERD) and respiratory symptoms; nine of 15 (60%) had evidence of pharyngeal reflux preoperatively. Antireflux procedures resulted in a significant decrease in pharyngeal reflux (7.9 to 1.6 episodes/24h; p <0.05) and esophageal acid exposure (7.5% to 2.1%; p <0.05). In patients with pharyngeal reflux and complete postoperative testing, three (60%) obtained improvement of respiratory symptoms and resolution of pharyngeal reflux. In two patients with recurrent respiratory symptoms after surgery, persistent pharyngeal reflux was detected. Conclusions: Operative treatment of GERD is effective in controlling extraesophageal reflux, measured subjectively and objectively. Evidence of pharyngeal reflux on pH testing helps to identify which patients with respiratory symptoms will benefit from an antireflux procedure.     

Gastrointestinal symptoms and patient satisfaction more than 1?year after laparoscopic Nissen fundoplication

Background  

Symptoms from poorly controlled gastroesophageal reflux disease (GERD) such as heartburn and regurgitation often resolve after laparoscopic Nissen fundoplication. Unfortunately, new gastrointestinal symptoms such as bloating may occur for some patients. Accurate data regarding the gastrointestinal symptoms experienced by patients who have had a laparoscopic fundoplication may help patients to make more informed decisions about pursuing surgery for their reflux disease.     

Laparoscopic fundoplication for symptomatic but physiologic gastroesophageal reflux

Esophageal pH monitoring identifies some patients who have physiologic amounts of esophageal acid exposure but have a strong correlation between symptoms of esophageal reflux events. These patients with symptomatic physiologic reflux probably have enhanced sensory perception of reflux events and may be difficult to control with acid-suppressive therapy. Little is known about the role of fundoplication in such patients. Patients with no endoscopic evidence of gastroesophageal reflux disease and a normal 24-hour pH composite score (<22.4 in our laboratory), but a symptom index (SI = number of symptoms with pH <4/total number of symptoms) greater than 50% were offered laparoscopic fundoplication if acid-suppressive therapy was unsatisfactory. This group comprised 18 (4%) of 459 patients undergoing fundoplication at our institution. Heartburn, dysphagia, and reflux symptoms were scored on a scale of 0 to 10 with patients on and off medicine preoperatively, and at a mean of 7.2 months (range 1 to 32 months) postoperatively. The 18 patients with symptomatic physiologic reflux (6 males and 12 females) had heartburn as a major complaint. Preoperative response to proton pump inhibitors for heartburn was 72% and for all symptoms was 60%. The group had a mean pH composite score of 14 (range 4 to 22). The symptom used to calculate the symptom index was heartburn in 12 patients, regurgitation in three, chest pain in two, and cough in one. An average of 18 symptoms (range 2 to 56) were recorded. The mean symptom index was 82 % (range 50% to 100%). A Nissen fundoplication was performed in nine patients and a Toupet fundoplication in nine. Surgery was successful (>90%) in alleviating reflux symptoms in 14 patients and partially successful (>75%) in three of the remaining four patients. Gas bloat and dysphagia were seen in one patient each. Fundoplication is effective at relieving reflux symptoms in carefully selected patients with symptomatic physiologic reflux, with minimal side effects.

Refractory gastroesophageal reflux disease as diagnosed by impedance-pH monitoring can be cured by laparoscopic fundoplication

Background

Some patients with typical (heartburn/regurgitation) symptoms of gastroesophageal reflux disease (GERD) are refractory to proton pump inhibitor (PPI) therapy. Impedance-pH monitoring can identify PPI-refractory patients who could benefit from laparoscopic fundoplication, but outcome data are scarce. We aimed to assess whether PPI-refractory GERD as diagnosed by impedance-pH monitoring can be cured by laparoscopic fundoplication.

Methods

Forty-four consecutive GERD patients with heartburn/regurgitation refractory to high-dose PPI therapy entered a 3-year outcome assessment following robot-assisted laparoscopic fundoplication. Preoperative on-PPI impedance-pH diagnostic criteria consisted of positive symptom association probability (SAP)/symptom index (SI), and/or abnormal percentage esophageal acid exposure time (%EAET), and/or abnormal number of total refluxes. GERD cure was defined by 3-year postoperative off-PPI normal impedance-pH findings with persistent symptom remission.

Results

Preoperatively, 24 of 38 (63 %) patients who completed the outcome assessment had a positive SAP/SI, 20 of 38 (53 %) for weakly acidic refluxes; 3 of 38 (8 %) patients had an abnormal %EAET, 11 of 38 (29 %) an abnormal number of total refluxes only. Postoperatively, heartburn/regurgitation recurred in 3 patients; abnormal impedance-pH findings were found in two of them, and they responded to PPI therapy. GERD cure was achieved in 34 of 38 (89 %) patients, 11 of 11 with an abnormal number of total refluxes as the only preoperative abnormal impedance-pH finding. Postoperatively, there was a significant decrease of the %EAET (1 vs. 0.1 %, P = 0.002) and of the number of total refluxes (68 vs. 8, P = 0.001), with the latter finding mainly due to a decrease in the number of weakly acidic refluxes.

Conclusions

Normal reflux parameters and persistent symptom remission at 3-year follow-up can be achieved with laparoscopic fundoplication in the majority of patients with PPI-refractory GERD as diagnosed by impedance-pH monitoring. On-PPI impedance-pH diagnostic criteria should include SAP/SI positivity, an abnormal %EAET, and an abnormal number of total refluxes. Weakly acidic refluxes have a major role in the pathogenesis of PPI-refractory GERD.     

Respiratory symptoms and dysphagia in patients with gastroesophageal reflux disease: a comparison of medical and surgical therapy

 Background: Gastroesophageal reflux disease (GERD) is a common condition and may frequently lead to dysphagia and respiratory symptoms. The aim of this study was to investigate the effects of medical and surgical therapy to control these symptoms. Methods: Eighty GERD patients with either dysphagia or respiratory symptoms were studied by means of a detailed symptom questionnaire, upper gastrointestinal endoscopy, esophageal manometry, 24-h esophageal pH monitoring and a barium esophagogram. All patients had been receiving medical therapy with proton-pump inhibitors and cisapride for 6 months. After withdrawal of medical therapy and relapse of GERD, 62 patients decided to undergo anti-reflux surgery (laparoscopic Nissen fundoplication in 19 and laparoscopic partial posterior fundoplication in 43 patients). Symptoms were assessed prior to treatment, at 6 months following medical therapy and 6 months after surgery. Results: Heartburn and esophagitis were effectively treated by medical and surgical therapy. Dysphagia was improved in all patients following surgery but only in 27% of patients following medical therapy. Improvement of respiratory symptoms was found in 86% of patients following surgery but only in 14% following medical therapy. Improvement of regurgitation was registered only following surgical therapy. Conclusions: Since medical treatment is likely to fail in GERD patients with complex symptoms such as dysphagia, regurgitation and respiratory symptoms, the need for surgery arises in these patients and may be the only successful treatment in the long term.

Laparoscopic fundoplication in elderly patients with gastroesophageal reflux disease

HYPOTHESIS: It is unclear if age should be considered a factor in the choice of treatment for gastroesophageal reflux disease (GERD) and if fundoplication in elderly patients is as safe and effective as it is in younger patients. We hypothesized that the outcome of laparoscopic antireflux operations in patients younger than 65 years is similar to that of patients 65 years and older. DESIGN: Retrospective review of findings from a prospectively acquired database. SETTING: University-based tertiary care center. PATIENTS: Three hundred four consecutive patients underwent laparoscopic fundoplication for GERD. Two hundred forty-one patients were younger than 65 years (group A; median age, 46 years), and 63 patients were 65 years or older (group B; median age, 69 years). MAIN OUTCOME MEASURES: Presence, duration, and severity of GERD symptoms; presence of a hiatal hernia or esophageal stricture; duration of operation; incidence of complications; and length of hospital stay. RESULTS: Elderly patients more often had regurgitation and respiratory symptoms in addition to heartburn. Hiatal hernias were more common among elderly patients (77% vs 51%). The duration of the operation was similar for the 2 groups. The incidence of intraoperative and postoperative complications was low and similar in the 2 groups. The median hospital stay was 24 hours for each group. Heartburn resolved in approximately 90% of patients in each group. CONCLUSIONS: Elderly patients more often had hiatal hernias and respiratory symptoms. Laparoscopic antireflux surgery was as safe in elderly patients as it was in younger patients, and clinical outcomes were as good.     

Evaluation of laparoscopic Toupet fundoplication as a primary repair for all patients with medically resistant gastroesophageal reflux

Background: This prospective study assesses the outcome results in 100 consecutive patients with gastroesophageal reflux disease (GERD) treated with a laparoscopic Toupet fundoplication. Methods: GERD was confirmed by 24-h pH study and/or esophagogastroduodenoscopy (EGD). Pre- and postoperative symptoms, operative times, and perioperative complications were recorded on standardized data forms. Early follow-up was at 3 months and late follow-up, including 24-h pH, manometry, and EGD was at 22 months. Results: Preoperative symptoms included heartburn (92%), regurgitation (58%), water brash (39%), and dysphagia (39%). Mean operative time was 3.2 hours. There were no conversions to celiotomy and there were no mortalities. The perioperative complication rate was 14%; 6% (5/83) of patients reported heartburn at 3 months and 20% (15/74) at 22 months. Early and late dysphagia was 20% (17/83) and 9% (7/74), respectively; 24-h pH testing was abnormal in 90% of symptomatic patients (9/10), 39% of asymptomatic patients (12/31), and 51% overall. Conclusions: Despite early improvement in reflux symptoms following laparoscopic Toupet fundoplications, there is a high incidence of recurrent GERD. Symptomatic follow-up underestimates the true incidence of 24-h pH-documented reflux. Based on these results we cannot recommend the laparoscopic Toupet repair for GERD patients with normal esophageal motility. Received: 24 March 1997/Accepted: 28 May 1997     

Chronic cough due to gastroesophageal reflux disease

BACKGROUND: Gastroesophageal reflux disease (GERD) can be overlooked as the cause of chronic cough (CC) when typical gastrointestinal symptoms are absent or minimal. We analyzed the outcomes of Nissen fundoplication (NF) for patients who failed medical therapy for CC attributable only to GERD (G-CC). We performed a prospective outcome evaluation of 21 consecutive patients with G-CC undergoing NF from 1997 to 2000 at a tertiary care university hospital. MATERIALS AND METHODS: Twenty-one patients without prior antireflux surgeries had G-CC diagnosed by a clinical profile and 24-h pH monitoring showing a cough-reflux correlation. Respiratory symptoms alone were present in 53% of patients. NF was performed when G-CC persisted despite intensive medical therapy, including an antireflux diet. Preoperatively, all patients underwent 24-h pH monitoring, esophageal manometry, barium swallow, gastric emptying study, bronchoscopy, and upper endoscopy. NF was utilized in all cases, laparoscopically in 18. Before and after surgery, patients graded their cough severity using the Adverse Cough Outcome Survey (ACOS). Quality of life was measured using the Sickness Impact Profile (SIP). Results: Postoperatively, 18 patients (86%) reported an improvement of their cough. G-CC considerably improved in 16/21 patients (76%), with complete resolution in 13 patients (62%). Mild to moderate improvement was found in 2 patients (10%). Patient-reported cough severity (ACOS) and quality of life (SIP) both significantly improved early (6-12 weeks) postoperatively and persisted during the long-term (1 year) follow-up. The average hospital length of stay was 1.78 +/- 0.2 (l-4) days for the laparoscopic (n = 18) and 6.3 +/- 1.2 (4-8) days for the open surgery (n = 3) groups. CONCLUSION: Twenty-four-hour esophageal pH monitoring is a valuable tool for preoperative cough-reflux correlation. Antireflux surgery is effective in carefully selected patients whose refractory CC is attributable only to GERD. NF controls the severity of cough while improving the quality of life. Outcomes are further enhanced using laparoscopic procedures with shorter hospital stays.     

Long-term outcomes of laparoscopic antireflux surgery for gastroesophageal reflux disease (GERD)-related airway disorder

A strong link exists between gastroesophageal reflux disease (GERD) and airway diseases. Surgical therapy has been recommended as it is more effective than medical therapy in the short term, but there is little data on the effectiveness of surgery long-term. We analyzed the long-term response of GERD-related airway disease after laparoscopic anti-reflux surgery (LARS). Methods In 2004, we contacted 128 patients with airway symptoms and GERD who underwent laparoscopic antireflux surgery (LARS) between 12/1993 and 12/2002. At median follow-up of 53 months (19–110 mo) we studied the effects on symptoms, esophageal acid exposure, and medication use and we analyzed the data to determine predictors of successful resolution of airway symptoms. Results Cough, hoarseness, wheezing, sore throat, and dyspnea improved in 65-75% of patients. Heartburn improved in 91 % (105/116) of patients and regurgitation in 92% (90/98). The response rate for airway symptoms was the same in patients with and without heartburn. Almost every patient took proton pump inhibitors (PPIs) preoperatively (99%, 127/128) and 61% (n = 78) were taking double or triple dose. Postoperatively, 33% (n = 45) of patients were using daily anti-acid therapy but no one was on double dose. The only factor that predicted a successful surgical outcome was the presence of abnormal reflux in the pharynx as determined by 24-hour pharyngeal pH monitoring. One hundred eleven (87%) patients rated their results as excellent (n = 78, 57%) or good (n = 33, 24%). Conclusion LARS provides an effective and durable barrier to reflux, and in so doing improves GERD-related airway symptoms in ∼70% of patients and improves typical GERD symptoms in ∼90% of patients. Pharyngeal pH monitoring identifies those patients more likely to benefit from LARS, but better diagnostic tools are needed to improve the response of airway symptoms to that of typical esophageal symptoms.     

Symptom-focused results after laparoscopic fundoplication for refractory gastroesophageal reflux disease—a prospective study

Background and aims  Symptoms of gastroesophageal reflux disease (GERD) are common in the general population. Although the results of laparoscopic fundoplication are well documented, there have been no reports on the operative outcome in patients refractory to or with only partial response to medical therapy for GERD. Patients–methods  Thirty-two patients with GERD, whose continuous high doses of medical treatment with proton-pump inhibitors produced no or only partial symptom relief, underwent laparoscopic Nissen fundoplication. Symptoms were evaluated with a standardized questionnaire preoperatively and 12 months after surgery. Results  The complete follow-up evaluation was obtained in 30 out of the 32 patients. The main symptoms before surgery were regurgitation (93%), heartburn (60%), epigastric pain (47%), and globus sensation (47%). All patients were relieved from heartburn, vomiting, and globus sensation. Dysphagia was relieved in 75% of the patients and regurgitation in 86%. Dysphagia as a new symptom occurred in 9%. The overall morbidity rate was 16%. Patient satisfaction rate was 87%. Conclusion  Laparoscopic fundoplication seems to be an effective treatment for severe, drug-resistant GERD. The high patient satisfaction rate and the positive therapeutic response in 95% of patients justify this procedure in this strictly selected group of patients.     

Preoperative evaluation of patients with gastroesophageal reflux disease

All patients who are candidates for laparoscopic fundoplication for the treatment of gastroesophageal reflux disease (GERD) should have a symptom review, barium swallow imaging, endoscopy, esophageal manometry, and ambulatory pH monitoring. The presence of a typical primary symptom, an abnormal 24-hour pH score, and a good response to acid-suppression therapy are predictive of a successful surgical outcome. The surgeon should be particularly wary of the following types of patients who may be referred for fundoplication but not have GERD: those who do not respond to proton pump inhibitors, those without esophagitis, those with only atypical symptoms, those in whom pH monitoring was done without previous manometry, and those with a borderline reflux score, severe vomiting, severe dysphagia and heartburn, unusual symptoms, severe depression, or morbid obesity.     

Laparoscopic Nissen fundoplication improves quality of life in patients with atypical symptoms of gastroesophageal reflux

Laparoscopic Nissen fundoplication has been shown to improve overall quality of life (QOL) in patients with gastroesophageal reflux, but most studies have not addressed patients with atypical symptoms. We investigated the effect of laparoscopic Nissen fundoplication on QOL using the Gastrointestinal Quality of Life Index (GIQLI) survey modified to address both typical (heartburn, regurgitation, dysphagia) and atypical (hoarse voice, chronic cough, adult-onset asthma, vocal cord polyps) symptoms. One-hundred forty-eight patients underwent laparoscopic Nissen fundoplication for gastroesophageal reflux disease (GERD) at UCLA Medical Center from January 1, 1995 to May 1, 2002. Surveys evaluating pre- and postoperative QOL were administered after surgery: 55 per cent of patients responded (82/148). Forty-eight per cent of all patients (72/148) had atypical symptoms. Perioperative morbidity and mortality were 8.8 per cent and 0.7 per cent, respectively. Mean length of postoperative stay was 2.96 +/- 1.5 days. Mean follow-up for the entire cohort was 18.5 months. Postoperative dysphagia not present before surgery occurred in 4.7 per cent of patients. Eighty per cent of patients were medication-free following surgery. QOL scores for all participants increased significantly from 52.5 +/- 15.3 preoperatively to 72.0 +/- 14.9 postoperatively (P < 0.0001). Patients with atypical symptoms or typical symptoms alone showed significant mean QOL score increases from 48.3 +/- 17.6 preoperatively to 71 +/- 15.7 postoperatively (P < 0.0001) and from 55.7 +/- 12.6 to 72.8 +/- 14.4 (P < 0.0001), respectively. Laparoscopic Nissen fundoplication can effectively improve overall QOL for patients with GERD. Patients with atypical GERD symptoms can experience increases in QOL similar to those with only typical gastrointestinal symptoms.     

Gastroesophageal reflux disease: symptoms versus pH monitoring results.

OBJECTIVES: The reason why some patients with gastroesophageal reflux disease (GERD) have symptoms of upper aerodigestive system irritation, while others mainly have gastroenterologic symptoms, is not well established. This retrospective case series study was designed to examine the existence of a correlation between symptoms and reflux characteristics, based on data obtained from esophageal pH monitoring. METHODS: The study population consisted of 139 patients; 97 patients presented with laryngopharyngeal symptoms of GERD, including unexplained hoarseness, throat clearing, chronic cough, laryngospasm, globus, throat pain, and 42 patients presented with gastroenterologic symptoms, including heartburn and regurgitation. The results of 24-hour, double-channel ambulatory esophageal pH monitoring were analyzed comparing 2 symptom groups. The incidence of abnormal acid reflux at the upper and lower esophageal segments and the effects of upright and supine positions on reflux parameters were evaluated. RESULTS: The incidence of laryngopharyngeal reflux was significantly higher in the laryngopharyngeal symptom group than in the other (52% versus 38%). The patients with laryngopharyngeal reflux from both groups showed no significant differences in terms of number of acid reflux episodes, percentage of times pH was 4, and esophageal acid clearance. Upright and supine parameters did not show significant differences between the patient groups. Upright acid reflux episodes were, however, common in both groups at the lower esophageal and laryngopharyngeal segments. CONCLUSION: Recent studies suggesting that otolaryngologic patients commonly show upright, daytime reflux with normal esophageal clearance and that typical GERD patients commonly have supine, nocturnal reflux with prolonged esophageal clearance are not supported by this study. This study indicates that acid reflux parameters and positional changes are not sufficient to explain why patients with GERD experience different symptoms. The regional symptoms of GERD may be attributed to the impairment of epithelial resistance, motor activity, and buffering systems for the esophageal antireflux barrier.     

Laparoscopic Nissen fundoplication offers high patient satisfaction with relief of extraesophageal symptoms of gastroesophageal reflux disease

Nissen fundoplication is applied for patients with gastroesophageal reflux disease (GERD), usually because of symptoms of esophageal injury. When presenting symptoms are extraesophageal, there is less enthusiasm for operative control of reflux because of concerns of etiology and efficacy. This study was undertaken to evaluate the efficacy of laparoscopic Nissen fundoplication in palliating extraesophageal symptoms of GERD. Patients were asked to score their symptoms before and after laparoscopic Nissen fundoplication on a Likert scale (0 = never/none to 5 = always/every time I eat). A total of 322 patients with extraesophageal symptoms (asthma, cough, gas/bloat, chest pain, and odynophagia) of 4 to 5 were identified and analyzed. After fundoplication, all extraesophageal symptom scores improved (P < 0.0001 for all, Wilcoxon matched-pairs test). Likewise, postoperative symptoms were noted to be greatly improved or resolved in 67 per cent to 82 per cent of patients for each symptom. Furthermore, after fundoplication, patients were less likely to modify their dietary (82% vs 49%) or sleeping habits (70% vs 28%) to avoid initiating/ exacerbating symptoms. Although extraesophageal symptoms are conventionally thought to be inadequately palliated by surgery, this study documents excellent relief of extraesophageal symptoms after laparoscopic Nissen fundoplication, denotes high patient satisfaction, and encourages application of laparoscopic Nissen fundoplication.     

The significance of pH and manometric testing after laparoscopic fundoplication

Laparoscopic antireflux surgery has become the standard operation for gastroesophageal reflux disease (GERD). This study examined the outcomes of laparoscopic antireflux surgery, hypothesizing that both subjective symptoms and objective pH would correlate with manometric parameters to reflect the absence of reflux after fundoplication. We evaluated 56 patients who underwent laparoscopic antireflux surgery. Preoperative and postoperative symptoms were documented by chart reviews and confirmed by telephone interviews with the patient. Preoperative pH probe and esophageal manometry studies were compared with postoperative studies performed 3 to 6 months after fundoplication. Subjective symptoms were correlated with objective measurements of acid reflux and lower esophageal sphincter pressure (LESP). The follow-up period was 3 to 29 months. Symptomatic improvement was seen in 91% of patients, and good to excellent improvement in preoperative symptoms was cited. Postoperatively, there was significant improvement in percentages of upright supine times when esophageal pH was less than 4 (p <0.001). There was an increase in LESP from an average of 16.9 mmHg preoperatively to 22.7 mmHg postoperatively (p <0.001). There was no correlation between postoperative LESP and symptoms or LESP and 24-h pH results. However, there was a predictive correlation between LESP and postoperative heartburn symptoms (p <0.001). These findings imply that symptom follow-up evaluation is adequate in the asymptomatic patient after laparoscopic fundoplication, and that routine physiologic testing is not necessary.     

Response of atypical symptoms of gastro-oesophageal reflux to antireflux surgery.

BACKGROUND: Atypical manifestations of gastro-oesophageal reflux (GOR) include asthma, chest pain, cough and hoarseness. The effectiveness of antireflux surgery for these symptoms is uncertain. The present study compared symptomatic response rates for typical and atypical GOR symptoms after fundoplication. METHODS: Between October 1991 and January 1998, 324 patients underwent laparoscopic fundoplication at Emory University Hospital and returned postoperative questionnaires. Severity of typical (heartburn) and atypical (asthma, chest pain, cough and hoarseness) GOR symptoms was reported by patients on a 0-4 scale before surgery, and at 6 and 52 weeks after operation. Patients were stratified based on preoperative symptoms into three groups: group 1 (severe heartburn/minimal atypical symptoms), group 2 (severe heartburn/severe atypical symptoms) and group 3 (minimal heartburn/severe atypical symptoms). RESULTS: In group 1 (n = 173) heartburn improved in 99 per cent and resolved in 87 per cent. In group 2 (n = 95) heartburn improved in 95 per cent and resolved in 76 per cent, and atypical symptoms improved in 94 per cent and resolved in 42 per cent. In group 3 (n = 56) atypical symptoms improved in 93 per cent and resolved in 48 per cent. Although all symptoms were improved by fundoplication, resolution was more likely for heartburn than for atypical symptoms. CONCLUSION: Atypical symptoms of GOR are improved by fundoplication, but symptom resolution occurs in fewer than 50 per cent of patients.     

Surgical management of gastroesophageal reflux and outcome after laryngectomy in patients using tracheoesophageal speech

BACKGROUND: Gastroesophageal reflux disease (GERD) is common in patients with head and neck carcinoma. The impact of laparoscopic fundoplication on laryngectomy patients with tracheoesophageal prostheses for voice restoration is unknown. METHODS: Nine laryngectomy patients who use tracheoesophageal speech underwent laparoscopic fundoplication for documented reflux. Preoperative and postoperative symptoms were recorded. Quality of speech was documented before and after fundoplication. RESULTS: Although 88% of patients had resolution of GERD symptoms, all developed bloating and hyperflatulence. There was no difference in quality of esophageal speech after laparoscopic fundoplication. CONCLUSIONS: Fundoplication in laryngectomy patients that use tracheoesophageal speech eliminates symptoms of gastroesophageal reflux and resolves regurgitation associated prosthesis erosion. Although nearly all patients are satisfied with outcome, there is a high incidence of postfundoplication bloating and hyperflatulence that may be life limiting. Poor quality tracheoesophageal speech should not be used as an indication for antireflux surgery.     

Postoperative esophageal physiology studies may help to predict long-term symptoms following laparoscopic Nissen fundoplication

Background Laparoscopic Nissen fundoplication is an established treatment for gastroesophageal reflux disease (GERD). Postoperative improvement in esophageal physiology can be indicative of successful surgery, but the degree to which it correlates with symptom control remains questionable. We have performed this study to assess the utility of postoperative esophageal physiology studies in predicting long-term symptomatic outcome. Methods Between August 1997 and August 2003, 145 patients with symptomatic GERD underwent laparoscopic Nissen fundoplication as part of a randomized trial. Four months after surgery patients were invited to have postoperative esophageal physiology studies. In November 2005, a postal questionnaire was sent to all patients in order to assess reflux symptomatology (DeMeester symptom score). Results Completed symptom questionnaires were returned by 108 patients (74%) after a median of 5.7 years postoperatively. Linear regression of manometry data showed a significant correlation between the level of postoperative neosphincter pressure either above or below the median and long-term scores for heartburn (p = 0.03), dysphagia (p = 0.02), regurgitation (p = 0.01), and total symptom score (p = 0.002). In contrast, there was no evidence of a significant correlation between results of postoperative esophageal pH studies and symptom scores. Conclusion Postoperative physiology studies, particularly manometry, may be predictive of long-term symptoms following laparoscopic Nissen fundoplication.
