Abstract
Gastroesophageal reflux disease (GERD) is nowadays a highly prevalent, chronic condition, with 10% to 30% of Western populations affected by weekly symptoms. Many patients with mild reflux symptoms are treated adequately with lifestyle modifications, dietary changes, and low-dose proton pump inhibitors (PPIs). For those with refractory GERD poorly controlled with daily PPIs, numerous treatment options exist. Fundoplication is currently the most commonly performed antireflux operation for management of GERD. Outcomes described in current literature following laparoscopic fundoplication indicate that it is highly effective for treatment of GERD; early clinical studies demonstrate relief of symptoms in approximately 85%-90% of patients. However it is still unclear which factors, clinical or instrumental, are able to predict a good outcome after surgery. Virtually all demographic, esophagogastric junction anatomic conditions, as well as instrumental (such as presence of esophagitis at endoscopy, or motility patterns determined by esophageal high resolution manometry or reflux patterns determined by means of pH/impedance-pH monitoring) and clinical features (such as typical or atypical symptoms presence) of patients undergoing laparoscopic fundoplication for GERD can be factors associated with symptomatic relief. With this in mind, we sought to review studies that identified the factors that predict outcome after laparoscopic total fundoplication.

Abstract
OBJECTIVES We set out to investigate the impact of the preoperative reflux pattern on long-term outcome after Nissen fundoplication. Recent studies disagree on whether patients with pathological upright reflux should be discouraged from undergoing surgery. METHODS A total of 338 patients underwent Nissen fundoplication. Of these, 234 of 289 patients had pathological acid exposure on preoperative 24-h esophageal pH monitoring and their reflux was classified as pathological upright (n=81), supine (n=55), or bipositional (n=98). Clinical outcomes and results of endoscopy, manometry, and 24-h pH monitoring were compared before surgery, and at 3 months and 5 years after surgery. RESULTS Patients with pathological upright and supine reflux had similar preoperative reflux parameters. In patients with pathological bipositional reflux, however, preoperative total acid exposure was higher than that in patients with upright or supine reflux (18.3% vs. 10.7 and 7.5%; P<0.001 and P<0.001). Prevalence of esophagitis was higher in patients with bipositional reflux than in those with upright reflux, both before (64.0 vs. 45.6%; P=0.035) and 3 months after surgery (16.0 vs. 3.5%; P=0.018). Before surgery, mean lower esophageal sphincter (LES) pressure was lower compared with the upright and supine reflux groups (1.0 vs. 1.5 and 1.6 kPa; P=0.007 and 0.005, respectively). The increase in quality of life, reduction of symptoms, use of acid-suppressing drugs, total acid exposure, and esophagitis were independent of reflux pattern at 3 months and 5 years after surgery (all P<0.05). Prevalence of recurrent pathological acid exposure was higher in the bipositional group than in the upright group (40.9 vs. 10.7%; P=0.013). Surgical reintervention was significantly more common in bipositional reflux patients (20.0 vs. 8.9% for upright and 4.1% for supine). CONCLUSIONS All three pathological reflux patterns respond favorably to Nissen fundoplication in the long term. Patients with pathological bipositional reflux, however, suffer from more severe disease with higher chance of recurrence and reoperation.

Abstract
OBJECTIVES Surgical treatment is a therapeutic option for patients with gastroesophageal reflux disease (GERD). It is unclear which patient characteristics influence postoperative success. The purpose of this paper was to review the literature on prognostic factors for patients with GERD treated with fundoplication. METHODS We searched Medline and the Cochrane Library Central for studies from 1966 through July 2007. We identified additional studies by reviewing bibliographies of retrieved articles and by consulting experts. We included English language studies that evaluated factors potentially affecting the outcomes after surgical treatments in patients with GERD. We recorded baseline patient characteristics associated with treatment efficacy, details on the study design, comparators, and definitions of outcomes. RESULTS We assessed 6,318 abstracts; 53 cohorts and 10 case-control studies met our inclusion criteria. Age, body mass index, sex, esophagitis grade, and dysmotility were generally not associated with treatment outcomes. There were no consistent associations between preoperative response to acid suppression medications, baseline symptoms, baseline acid exposure, degree of lower esophageal sphincter competence, or position of reflux and surgical outcomes. Certain psychological factors might be associated with worse treatment outcomes. CONCLUSIONS Although several preoperative predictors of surgical outcomes have been described, the quality and consistency of the data were mixed and the strength of the associations remains unclear. Additional studies with improved methodological designs are needed to better define which patient characteristics are associated with surgical outcomes following fundoplication.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is a very common disorder that substantially affects the patient's quality of life. AIM Our aim was to detect the frequency of GERD in patients with hiatal hernia (HH), to compare the acid reflux pattern in patients with and without HH, and to search the relationship between the erosive gastroesophageal reflux (GER) and HH. METHODS Forty patients with HH diagnosed by at least two methods, and 121 patients with GERD as a control group were studied. The frequency of GERD in patients with HH, the acid reflux pattern, the relation of body mass index and erosive esophagitis with HH and control group was studied. RESULTS Among patients with HH 67.5% of patients had GER. On comparison of acid reflux pattern, the isolated distal esophageal reflux was seen more in patients with HH than in the control group (P < 0.0001). Erosive GERD was seen more in patients with HH than in the control group (P = 0.017). There was no difference in body mass indices between patients with HH and erosive gastroesophageal reflux disease and patients with HH and non-erosive GERD. CONCLUSION Hiatal hernia is very closely associated with GERD, and isolated distal esophageal reflux is seen more in patients with HH than in patients without HH. There is no effect of body mass index on GER in patients with HH.

Abstract
BACKGROUND Some studies have suggested that patients with predominantly upright reflux have a poor outcome after laparoscopic antireflux surgery. It has been proposed that this might be related to gastric emptying. The aim of this study was to evaluate the relationship between preoperative upright reflux pattern, gastric emptying rate and outcome after laparoscopic fundoplication. METHODS Patients presenting for antireflux surgery underwent 24-h ambulatory pH testing and dual-isotope radionuclide gastric emptying studies. Reflux pattern was determined by the acid exposure in the distal oesophagus (percentage of time at pH < 4) during supine and upright posture. Outcome after fundoplication was assessed by a standardized postal questionnaire administered at 3 months, and 1, 2 and 5 years after surgery. RESULTS Of 372 patients identified from a prospectively maintained database, 109 had upright reflux, 57 supine reflux and 206 bipositional reflux. Overall patient satisfaction was not influenced by reflux pattern at any time after surgery. Delayed gastric emptying was documented in 31.0 per cent of patients, but there was no relationship with reflux pattern. CONCLUSION Patients with upright reflux did not have a less favourable outcome after fundoplication. Categorizing patients according to reflux pattern is of no value in predicting outcome or selecting patients for surgery.

Abstract
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.

Abstract
The reason why patients with isolated supine reflux do not reflux in the upright position and patients with isolated upright reflux do not reflux in the supine position is unknown. Our objective was to determine the characteristics of the crura, lower esophageal sphincter, crurasphincter dynamics, and esophageal body on manometry, endoscopy, and X-ray in patients with isolated upright and isolated supine reflux. Eighty consecutive patients with isolated upright reflux were compared with 82 consecutive patients with isolated supine reflux. Manometrically there was no difference in lower esophageal sphincter characteristics and esophageal contractions between the two groups. The prevalence of a hiatal hernia on manometry was similar between upright and supine refluxers (88% vs 88%). Upright refluxers had shorter hiatal hernias [median (interquartile range) 1.1 (0.65–1.8) vs 1.2 (1–2.3), P < 0.046)]. The median crural pressure, crura-sphincter pressure gradient, and crura-sphincter pressure ratio in upright refluxers was 14.96 (9.5–21.27), 3.28 (1.7–12.2), and 1.33 (0.87–2.8) mm Hg, respectively. These values were significantly higher ( P < 0.001) in supine refluxers at 21.43 (16.6–29.9), 10.66 (4.3–19.7), and 2.1 (1.3–4.2) mm Hg, respectively. We conclude that the significantly higher crural pressure in patients with supine reflux acts as a mechanical ring and as a physiologic protector against the unfolding of the sphincter in the postprandial and upright periods. Higher crura-sphincter pressure gradient and larger-size hiatal hernias in patients with supine reflux results in pressurization of the hernia sac and subsequent reflux when these patients are in a supine position.

Abstract
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.

Abstract
OBJECTIVE To evaluate prospectively the outcome of laparoscopic fundoplication in a large cohort of patients with typical symptoms of gastroesophageal reflux. SUMMARY BACKGROUND DATA The development of laparoscopic fundoplication over the past several years has resulted in renewed interest in the surgical treatment of gastroesophageal reflux disease (GERD). METHODS One hundred patients with typical symptoms of GERD were studied. The study was limited to patients with positive 24-hour pH studies and "typical" symptoms of GERD. Laparoscopic fundoplication was performed when clinical assessment suggested adequate esophageal motility and length. Outcome measures included assessment of the relief of the primary symptom responsible for surgery; the patient's and the physician's evaluation of outcome; quality of life evaluation; repeated upper endoscopy in 30 patients with presurgical esophagitis; and postsurgical physiologic studies in 28 unselected patients, consisting of 24-hour esophageal pH and lower esophageal sphincter manometry. RESULTS Relief of the primary symptom responsible for surgery was achieved in 96% of patients at a mean follow-up of 21 months. Seventy-one patients were asymptomatic, 24 had minor gastrointestinal symptoms not requiring medical therapy, 3 had gastrointestinal symptoms requiring medical therapy, and 2 were worsened by the procedure. Eighty-three patients considered themselves cured, 11 were improved, and 1 was worse. Occasional difficulty swallowing not present before surgery occurred in 7 patients at 3 months, and decreased to 2 patients by 12 months after surgery. There were no deaths. Clinically significant complications occurred in four patients. Median hospital stay was 3 days, decreasing from 6.3 in the first 10 patients to 2.3 in the last 10 patients. Endoscopic esophagitis healed in 28 of 30 patients who had presurgical esophagitis and returned for follow-up endoscopy. Twenty-four-hour esophageal acid exposure had returned to normal in 26 of 28 patients studied after surgery. Lower esophageal sphincter pressures had also returned to normal in all patients, increasing from a median of 5.1 mmHg to 14.9 mmHg. CONCLUSIONS Laparoscopic Nissen fundoplication provides an excellent symptomatic and physiologic outcome in patients with proven gastroesophageal reflux and "typical" symptoms. This can be achieved with a hospital stay of 48 hours and a low incidence of postsurgical complications.
