Abstract
Patients with gastroesophageal reflux disease (GERD) may present with a variety of symptoms, including heartburn, regurgitation, dysphagia, chronic cough, laryngitis, or even asthma. Therefore, the clinical presentation of GERD varies among individuals and conversely symptoms not always correspond to the presence of actual reflux. For that reason, the diagnosis poses certain challenges to the physician. To overcome these challenges, a thorough clinical examination followed by objective functional testing could improve diagnostic accuracy. In addition, a proper evaluation of patients with GERD can help in identifying those who will likely benefit the most from an antireflux procedure. The diagnostic work-up of these patients should include: symptomatic evaluation, upper endoscopy, barium swallow, high-resolution manometry, and ambulatory pH monitoring. Once a proper diagnosis of GERD is achieved, antireflux surgery is an excellent option for patients with partial control of symptoms with medication, for patients who do not want to be on long-term medical treatment (compliance/cost), or when complications of medical treatment occur.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) may present with heartburn, regurgitation, dysphagia, chronic cough, laryngitis, or even asthma. The clinical presentation of GERD is therefore varied and poses certain challenges to the physician, especially given the limitations of the diagnostic testing. DISCUSSION The evaluation of patients with suspected GERD might be challenging. It is based on the evaluation of clinical features, objective evidence of reflux on diagnostic testing, correlation of symptoms with episodes of reflux, evaluation of anatomical abnormalities, and excluding other causes that might account for the presence of the patient's symptoms. CONCLUSIONS The diagnostic evaluation should include multiple tests, in addition to a thorough clinical examination.

Abstract
Gastric necrosis is a rare condition because of the rich blood supply and the extensive submucosal vascular network of the stomach. "Gas-bloat" syndrome is a well known Nissen fundoplication postoperative complication. It may cause severe gastric dilatation, but very rarely an ischemic compromise of the organ. Other factors, such as gastric outlet obstruction, may concur to cause an intraluminal pressure enough to blockade venous return and ultimately arterial blood supply and oxygen deliver, leading to ischaemia. We report a case of a 63-year-old women, who presented a total gastric necrosis following laparoscopic Nissen fundoplication and a pyloric phytobezoar which was the trigger event. No preexisting gastric motility disorders were present by the time of surgery, as demonstrated in the preoperative barium swallow, thus a poor mastication (patient needed no dentures) of a high fiber meal (cabbage) may have been predisposing factors for the development of a bezoar in an otherwise healthy women at the onset of old age. A total gastrectomy with esophagojejunostomy was performed and patient was discharged home after a 7-d hospital stay with no immediate complications. We also discuss some technical aspects of the procedure that might be important to reduce the incidence of this complication.

Abstract
OBJECTIVES Obesity has been associated with gastroesophageal reflux disease (GERD) but the relationship between body mass index (BMI) and esophageal acid exposure remains poorly understood. We hypothesized that overweight (OW) and obese (OB) patients with GER symptoms would have a higher degree of esophageal acid exposure than with normal weight (NW) patients. METHODS 157 patients separated in groups according to BMI were studied for 48h while off antisecretory medications using ambulatory wireless capsule pH-metry. The pH capsule was appropriately positioned and esophageal pH data were collected. Appropriate univariate and multivariate statistical methods were used. RESULTS Groups did not differ in age, but more women were in the NW group. OB patients had a fivefold increase in odds for abnormal total acid exposure compared with NW (OR=5.01; 95% CI 2.94, 12.95). Total acid exposure time (AET) was elevated in OB (8.7%+/-5.1%) compared with NW (5.3%+/-5.2%; P<0.05). AET was highest during awake, upright periods. The DeMeester score was higher in OB (31.7+/-19.2) and OW (26.0+/-16.8) groups compared with the NW (19.8+/-17.6) group (P<0.001). AET increased from day 1 to day 2 in the OB group only. CONCLUSIONS This is the first study to report a positive relationship between BMI and esophageal acid exposure time using prolonged, continuous wireless esophageal pH-metry. Abnormal AET was more frequent in OB patients. Variability in AET increased from day 1 to day 2 in the OB group, supporting the use of more prolonged pH studies in subsets of patients.

Abstract
INTRODUCTION It has been postulated that in patients with connective tissue disorders (CTD) and gastroesophageal reflux disease (GERD), esophageal function is generally deteriorated, often with complete absence of peristalsis. This belief has led to the common recommendation of avoiding antireflux surgery for fear of creating or worsening dysphagia. METHODS We hypothesized that in most patients with CTD and GERD: (a) esophageal function is often preserved; (b) peristalsis is more frequently absent when end-stage lung disease (ESLD) is also present; (c) a tailored surgical approach (partial or total fundoplication) based on the findings of esophageal manometry allows control of reflux symptoms without a high incidence of postoperative dysphagia. Forty-eight patients with CTD were evaluated by esophageal manometry and 24-hour pH monitoring (EFT). Twenty patients (group A) had EFT because of foregut symptoms, and 28 patients with ESLD (group B) had EFT as part of the lung transplant evaluation. Two hundred and eighty-six consecutive patients with GERD by pH monitoring served as a control group (group C). A laparoscopic fundoplication was performed in two group A patients (total), eight group B patients (three patients total, five patients partial) and in all group C patients (total). RESULTS Esophageal peristalsis was preserved in all patients with CTD and GERD. In contrast, peristalsis was absent in about half of patients when ESLD was also present. A tailored surgical approach resulted in control of reflux symptoms in all patients. One patient only developed postoperative dysphagia, which resolved with two Savary dilatations. CONCLUSION These data show that esophageal motor function is preserved in most patients with CTD, so that they should be offered antireflux surgery early in the course of their disease to prevent esophageal and respiratory complications. In patients with ESLD in whom peristalsis is absent, a partial rather than a total fundoplication should be performed, as it allows control of reflux symptoms while avoiding postoperative dysphagia.

Abstract
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.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is prevalent among patients with end-stage lung disease (ESLD). This disease can lead to microaspiration and may be a risk factor for lung damage before and after transplantation. A fundoplication is the best way to stop reflux, but little is known about the safety of elective antireflux surgery for patients with ESLD. This study aimed to report the safety of laparoscopic fundoplication for patients with ESLD and GERD before or after lung transplantation. METHODS Between January 1997 and January 2007, 305 patients were listed for lung transplantation, and 189 patients underwent the procedure. In 2003, routine esophageal studies were added to the pretransplantation evaluation. After the authors' initial experience, gastric emptying studies were added as well. RESULTS A total of 35 patients with GERD or delayed gastric emptying were referred for surgical intervention. A laparoscopic fundoplication was performed for 32 patients (27 total and 5 partial). For three patients, a pyloroplasty also was performed. Two patients had a pyloroplasty without fundoplication. Of the 35 operations, 15 were performed before and 20 after transplantation. Gastric emptying of solids or liquids was delayed in 12 (92%) of 13 posttransplantation studies and 3 (60%) of 5 pretransplantation studies. All operations were completed laparoscopically, and 33 patients recovered uneventfully (94%). The median hospital length of stay was 2 days (range, 1-34 days) for the patients admitted to undergo elective operations. Hospitalization was not prolonged for the three patients who had fundoplications immediately after transplantation. CONCLUSIONS The results of this study show that laparoscopic antireflux surgery can be performed safely by an experienced multidisciplinary team for selected patients with ESLD before or after lung transplantation, and that gastric emptying is frequently abnormal and should be objectively measured in ESLD patients.

Abstract
BACKGROUND Barium swallow is considered essential in the preoperative assessment of gastroesophaeal reflux disease and hiatal hernias. The objective of this study was to investigate the effective value of a barium swallow if complementary to the commonly recommended endoscopy before laparoscopic antireflux and hiatal hernia surgery. METHODS We prospectively evaluated 40 consecutive patients who were tested with preoperative barium swallow and endoscopy before laparoscopic surgery for gastroesophageal reflux disease and/or symptomatic hiatal hernia. Results regarding the presence and the type of hiatal hernia found by barium swallow and endoscopy were correlated with the intraoperative finding as the reference standard. RESULTS Intraoperative findings revealed 21 axial, 7 paraesophageal, and 12 mixed hiatal hernias. Barium swallow and endoscopy allowed the diagnosis of hiatal hernia in 75% and 97.5%, respectively (p = 0.003). The correct classification of hiatal hernia was confirmed in 50% by barium swallow and 80% by endoscopy (p = 0.005). CONCLUSIONS Although barium swallow is recommended as an important diagnostic tool in the workup before surgical antireflux and hiatal hernia therapy, our results suggest that if mandatory endoscopy is performed preoperatively, a barium swallow does not provide any further essential information. It seems that barium swallow can be omitted as a basic diagnostic test before primary laparoscopic antireflux and hiatal hernia surgery.

Abstract
OBJECTIVES The association between gastroesophageal reflux disease and idiopathic pulmonary fibrosis has not been fully characterized. The aims of this study were to determine in patients with idiopathic pulmonary fibrosis (1) the prevalence of reflux symptoms, (2) the esophageal manometric profile, and (3) the prevalence of proximal and distal esophageal reflux. METHODS Between May 1999 and March 2006, 30 patients with idiopathic pulmonary fibrosis were referred to the Swallowing Center at the University of California San Francisco. Each patient underwent a structured symptom assessment, esophageal manometry, and 24-hour dual sensor ambulatory pH monitoring. RESULTS Twenty (67%) patients had abnormal esophageal reflux. Typical reflux symptoms, although more common in those with reflux, were not reliable as a screening test (sensitivity 65%, specificity 71%). Sixty-five percent of patients with abnormal reflux had a hypotensive lower esophageal sphincter. Abnormal esophageal peristalsis was more common among those with reflux (50% vs 10%; P = .03). In 9 (30%) patients, acid refluxed into the proximal esophagus for over 1% of the study time. CONCLUSIONS A majority of patients with idiopathic pulmonary fibrosis have pathologic reflux. Symptoms do not distinguish between those with and without reflux. In these patients, reflux is associated with a hypotensive lower esophageal sphincter and abnormal esophageal peristalsis, and often extends into the proximal esophagus.

Abstract
BACKGROUND The usefulness of the anatomy-function-pathology (AFP) score was examined to evaluate its prediction of recurrence after laparoscopic fundoplication for erosive reflux esophagitis. METHODS Of the patients undergoing laparoscopic fundoplication for erosive reflux esophagitis of Los Angeles classification grade A or higher from December 1994 to December 2004, 107 who underwent preoperative barium esophagogram, pH monitoring, and endoscopy were selected as subjects. The AFP score was calculated by A, F, and P factor grades of the AFP classification. By comparing patients with and without recurrence, the usefulness of the AFP score for predicting recurrence was examined. RESULTS Reflux esophagitis recurred in seven patients. No significant difference in age, sex, or A or F factor was observed between the groups, whereas a significant difference was observed in the P factor (p = 0.008). On the other hand, the mean AFP score in the recurrence group was 16.9 +/- 5.3, whereas that in the nonrecurrence group was 8.9 +/- 5.3 (p = 0.0021). Among the patients with a score of 17 points or more (n = 23), recurrence was found in 6 patients (26%). On the other hand, among the patients with a score lower than 17 points (n = 84), recurrence was found in 1 patient, but not in the remaining 83 patients (1%). Sensitivity was thus 85.7% (95% confidence interval [CI], 42.1-99.6), and specificity was 83% (95% CI, 74.2-89.8). The positive predictive value was 26.1% (95% CI, 10.2-48.4), and the negative predictive value was 98.8% (95% CI, 93.5-99.9). Multiple logistic regression analysis was performed, and receiver operating characteristics curves were obtained. The area under the curve for the AFP score was 0.8457, whereas that for the P factor was 0.7907 (p = 0.0045), suggesting that the AFP score may more accurately predict recurrence than the P factor. CONCLUSION The AFP score may be useful for predicting postoperative recurrence. If surgery is performed when the AFP score is lower than 17 points, the likelihood of postoperative recurrence is expected to be very low.

Abstract
OBJECTIVE To determine the prevalence and proximal extent of gastroesophageal reflux (GERD) in patients awaiting lung transplantation. BACKGROUND GERD has been postulated to contribute to accelerated graft failure in patients who have had lung transplantations. However, the prevalence of reflux symptoms, esophageal motility abnormalities, and proximal esophageal reflux among patients with end-stage lung disease awaiting lung transplantation are unknown. METHODS A total of 109 patients with end-stage lung disease awaiting lung transplantation underwent symptomatic assessment, esophageal manometry, and esophageal pH monitoring (using a probe with 2 sensors located 5 and 20 cm above the lower esophageal sphincter). RESULTS Reflux symptoms were not predictive of the presence of reflux (sensitivity, 67%; specificity, 26%). Esophageal manometry showed a high prevalence of a hypotensive lower esophageal sphincter (55%) and impaired esophageal peristalsis (47%) among patients with reflux. Distal reflux was present in 68% of patients and proximal reflux was present in 37% of patients. CONCLUSIONS These data show that in patients with end-stage lung disease: 1) symptoms were insensitive and nonspecific for diagnosing reflux; 2) esophageal motility was frequently abnormal; 3) 68% of patients had GERD; 4) in 50% of the patients with GERD, acid refluxed into the proximal esophagus. We conclude that patients with end-stage lung disease should be screened with pH monitoring for GERD.

Abstract
INTRODUCTION The introduction of wireless pH monitoring has been touted as a significant advance in the diagnosis of gastroesophageal reflux and associated disorders. We prospectively enrolled patients in a research registry to assess the feasibility and safety in clinical use. METHODS All patients undergoing endoscopy with wireless pH studies (Medtronic Bravo pH system) for a 12-month period starting in April 2004 were prospectively enrolled. Probes were placed 6 cm above the endoscopically localized squamocolumnar junction. Successful completion was defined as at least 24 hours of pH recording. Safety data were obtained by review of patient diaries. All results are given as median with 25% to 75% confidence interval (CI). RESULTS A total of 217 studies with endoscopy and capsule placement were performed (65% women; median age, 51 years; range, 42-58 years) and included in the study; 1 patient refused participation in the registry and 5 studies were performed without preceding endoscopy and were excluded from this analysis. The pH study was successfully completed in 95.1%; early capsule detachment (1 hours; CI, 0-5 hours) or receiver malfunction occurred in 7 and 2 cases, respectively. There were no immediate adverse effects; 18 patients (9%) complained about significant chest discomfort, associated with odyno- or dysphagia, requiring removal of the capsule in 3 patients (1.5%). Of the completed studies, 56% were abnormal with 32.2% being abnormal on both days, whereas 16.1% and 6.9% only showed increased acid exposure on day 1 or 2, respectively. The higher likelihood of abnormal results for day 1 was associated with a significantly increased esophageal acid exposure during the first 6 hours after capsule insertion on day 1 (total time with pH < 4: 6.9%; CI, 3.2%-16.5%) compared with the corresponding time on day 2 (5.0%; CI, 0.9%-10.8%; P < 0.01), without differences esophageal acidification during the remaining time or differences in recorded activity. CONCLUSIONS Using a large registry of patients with suspected gastroesophageal reflux symptoms, our data show that wireless pH studies can be safely completed in more than 90% of patients. Whereas variability during prolonged recordings should be expected, the significantly higher likelihood of abnormal findings during the initial period of pH monitoring suggests a systematic influence of endoscopy and associated premedication, typically performed prior to capsule insertion, which needs to be considered when pH data are analyzed.

Abstract
This study determines the relationship among esophageal dysmotility, esophageal acid exposure, and esophageal mucosal injury in patients with gastroesophageal reflux disease (GERD). A total of 827 patients with GERD (confirmed by ambulatory pH monitoring) were divided into three groups based on the degree of mucosal injury: group A, no esophagitis, 493 patients; group B, esophagitis grades I to III, 273 patients; and group C, Barrett's esophagus, 61 patients. As mucosal damage progressed from no esophagitis to Barrett's esophagus, there was a significant decrease in lower esophageal sphincter pressure and amplitude of peristalsis in the distal esophagus, with a subsequent increase in the number of reflux episodes in 24 hours, the number of reflux episodes longer than 5 minutes, and the reflux score. These data suggest that in patients with GERD, worsening of esophageal mucosal injury may determine progressive deterioration of esophageal motor function with impairment of acid clearance and increase of esophageal acid exposure. These findings suggest that Barrett's esophagus is an end-stage form of gastroesophageal reflux, and that if surgical therapy is performed early in the course of the disease, this cascade of events might be blocked.

Patti MG, Robinson T, Galvani C, Gorodner MV, Fisichella PM, Way LW. Total fundoplication is superior to partial fundoplication even when esophageal peristalsis is weak1 1No competing interests declared. J Am Coll Surg 2004; 198:863-9; discussion 869-70. [PMID: 15194064 DOI: 10.1016/j.jamcollsurg.2004.01.029] [Citation(s) in RCA: 88] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2003] [Revised: 01/14/2004] [Accepted: 01/14/2004] [Indexed: 02/09/2023]
Abstract
BACKGROUND About a decade ago, partial (240 degrees) fundoplication became popular for treating gastroesophageal reflux disease in cases where the patient's primary esophageal peristalsis was weak. A total (360 degrees) fundoplication was reserved for patients with normal peristalsis (tailored approach). The theory was that partial fundoplication was an adequate antireflux measure, and by posing less resistance for the weak esophageal peristalsis to overcome, it would give rise to less dysphagia. Short-term results seemed to confirm these ideas. STUDY DESIGN This study reports the longterm followup of patients in whom a tailored approach (type of wrap chosen to match esophageal peristalsis) was used, and the results of a nonselective approach, using a total fundoplication regardless of the amplitude of esophageal peristalsis. We analyzed clinical and laboratory findings in 357 patients who had an operation for gastroesophageal reflux disease between October 1992 and November 2002. Group 1 was composed of 235 patients in whom a tailored approach was used between October 1992 and December 1999 (141 patients, partial fundoplication and 94 patients, total fundoplication). Group 2 contained 122 patients in whom a nonselective approach was used (total fundoplication regardless of quality of peristalsis). RESULTS In group 1, heartburn from reflux (ie, pH monitoring test was abnormal) recurred in 19% of patients after partial fundoplication and in 4% after total fundoplication. In group 2, heartburn recurred in 4% of patients after total fundoplication. The incidence of postoperative dysphagia was similar in the two groups. CONCLUSIONS These data show that laparoscopic partial fundoplication was less effective than total fundoplication in curing gastroesophageal reflux disease, and compared with a partial (240 degrees) fundoplication, a total (360 degrees) fundoplication was not followed by more dysphagia, even when esophageal peristalsis was weak.
