[Dynamic graciloplasty in the treatment of severe fecal incontinence--2 case reports].

Severe fecal incontinence is a serious problem not only for the patient whose quality of life is diminished, but also for the surgeon, who sometimes has difficulties how to manage all the aspects of this complicated condition. Conservative treatment is often ineffective, while operative sphincter repair is feasible only when anal sphincter is relatively functional and conserved. Dynamic graciloplasty is a method where functional anal neosphincter is constructed by transposing m. gracilis and wrapping it around the anal canal with subsequent implantation of electric neurostimulator and electrodes. Relatively good continence can be achieved with this technique, especially in-patients where all other therapeutic options failed. We present two patients, 25 and 21 years old, operated on our department, both suffered from severe fecal incontinence from the time they were born. They were interviewed, underwent a physical examination and evaluated by anal manometry, defecography and electromyography. Severe fecal incontinence was revealed (18 and 20, according to the Continence grading scale). In both cases, Gamma graciloplasty was performed. At first patient, implantation of the neurostimulator was performed 8 months after graciloplasty, while in second case, both graciloplasty and implantation of the electrodes with neurostimulator were performed at the same time. Postoperative recovery was uneventful in both cases. There was minor infection of the perineal wound in one patient. Electrostimulation training program was started on 9th postoperative day in both cases. Functional results were revealed by questionnaire and anal manometry. The quality of life was significantly improved in both cases, with good continence and psychological recovery. Anal manometry revealed increased anal contraction pressure comparing with preoperative basal and squeeze pressures. Dynamic graciloplasty is a relatively new; high specialized method in treatment of intractable, fecal incontinence. It is safe and reliable procedure in hands of an well-experienced surgeon, if well indicated and performed.

Immediate effects of endoscopic sphincterotomy on sphincter of Oddi motility.

The evidence exists that incomplete sphincterotomy in patients with biliary tract diseases may result in early symptoms reoccurrence or lack of improvement. Sphincter of Oddi manometry (SOM) can be used to verify the completeness of the procedure. The purpose of the study was to investigate the immediate effects of biliary endoscopic sphincterotomy (BES) and common bile duct stones (CBDS) clearance on biliary sphincter of Oddi (SO) motility. Moreover the percentage of incomplete sphincterotomies was estimated. 26 patients (6 male, 20 female, 24-93 years) with confirmed choledocholithiasis were investigated. All underwent BES followed by CBDS extraction, and then SO manometry (SOM) was performed. Moreover 6 patients underwent SOM prior to BES. SOM was performed with a triple lumen 5 Fr catheter attached to the water perfused low compliance system. Immediately after sphincterotomy and extraction of the CBDS common bile duct pressure dropped from a mean of 10.9 mmHg to 2.9 mmHg (p < 0.05). Similarly basal biliary sphincter pressure decreased from 22.7 mmHg to 7.3 mmHg (p < 0.05). 20 patients presented duodeno-choledochal gradient of less than 5 mmHg. However only 10 patients had also basal sphincter pressure lower than 5 mmHg. The phasic sphincter activity was abolished in 16 patients, whereas phasic contractions persisted in 10 patients. Seven patients displayed uncoordinated, low amplitude contractility. BES significantly decreases SO and CBD pressures, but when performed for CBDS extraction, commonly does not abolish SO motor activity nor ablate choledocho-duodenal gradient. Therefore to confirm the completeness of sphincterotomy, SO manometry is recommended.

Selection criteria and long-term results of surgery in symptomatic rectocele.

BACKGROUND: The aim of this study was to confirm some selection criteria for the transrectal repair of the anterior rectocele and to compare our surgical results with those reported in the literature. METHODS: From January 1992 to December 1999, 30 females (mean age 52.9 years, range 28-70 yrs) affected by anterior rectocele were prospectively evaluated with a standard questionnaire, clinical examination, proctosigmoidoscopy, colonic transit time, dynamic defecography, anal EMG, anal manometry. Then, they were submitted to transrectal repair of rectocele with anterior plication of the rectal muscular wall. Fourteen (46.6%) of them were also submitted to perineal levatorplasty. Patients were followed postoperatively (mean 25.7 months) with the same standard questionnaire, clinical examination, defecography, and manometry. Results were tested by Fisher's Exact text, Wilcoxon's test, and "t"-test. RESULTS: Rectal dyschezia, incomplete evacuation, digital help in defecating, mean stool frequency, and rectal bleeding significantly improved. After 3 months, 30% of patients had no complaints, 40% had only 1-2 episodes/month complaints, 13.3% had evacuation only using laxatives, and 16.6% were unchanged. Defecography showed a significant reduction of the rectocele in 70% of patients after 3 months. Manometric parameters were not significantly modified. Four (28.6%) out of 14 patients submitted to perineal levatorplasty complained of dyspareunia. CONCLUSIONS: Our surgical results were comparable with those reported in the literature, with more than 80% of successful outcome. Preoperative clinical data and defecography were confirmed to be basic parameters in selecting patients for surgery. Colonic transit time, anal EMG, and anorectal manometry demonstrated to be useful to recognize conditions as slow colonic transit time, peripheral denervation, and reduced voluntary contraction that could lead to a less satisfactory outcome after surgery, and might benefit with a postoperative perineal rehabilitation by biofeedback and anal electrostimulations. The perineal levatorplasty is not suitable in young females, due to the risk of dyspareunia.

Role of transperineal Doppler and ultrasound in evaluating anal sphincter injury after stapled haemorrhoidopexy.

The stapler treatment first described by Longo is considered by some authors to be a good technical solution for mucohaemorrhoidectomy. The aim of the present prospective study was to assess the function and morphology of the internal and external anal sphincters preoperatively and one month after surgery by means of a clinical examination, anorectal manometry and transperineal ultrasound. Ten patients (6 M, 4 F) underwent rectal mucosal prolapsectomy according to Longo. Anoscopy, anorectal manometry and transperineal ultrasound were performed in all patients preoperatively and again one month after surgery. The thickness and integrity of the internal and external anal sphincters were ascertained and colour Doppler was performed to assess the presence, quantity and size of any haemorrhoid swellings. All anatomical specimens underwent histological examination in search of smooth muscle fibres. Anorectal manometry revealed no postoperative sphincter tone defects. Transperineal ultrasound detected no postoperative sphincter lesions and the presence of venous swellings (always present at preoperative colour Doppler) never persisted at postoperative follow-up. The mean follow-up was 52.7 days (range: 31-151). Transperineal ultrasound proved useful in demonstrating the lifting of the mucohaemorrhoid prolapse within the ampulla of the rectum one month after surgery. The Longo procedure, in our albeit limited experience, caused no sphincter lesions.

Radionuclide gastroesophageal motor studies.

Disorders of the upper digestive tract have a high impact on modern society, in terms of both direct and indirect health care costs and of social burden. The most common presenting symptom is either dysphagia or dyspepsia. Discriminating specific diagnoses within this wide group of diseases requires sound clinical judgment and application of procedures to distinguish organic from nonorganic disease and to further characterize the functional or motility disturbance of nonorganic diseases. Non-radionuclide-based diagnostic techniques include both noninvasive tests (upper gastrointestinal barium series, ultrasonography, and breath test for gastric emptying) and invasive procedures (fiberoptic endoscopy, esophagogastroduodenoscopy, pharyngeal manometry, stationary esophageal manometry, 24-h pH monitoring, esophageal biliary reflux monitoring, multichannel intraluminal impedance, and electrogastrography). Some of these techniques are not well tolerated by patients or not widely available. Radionuclide transit/emptying scintigraphy provides a means of characterizing exquisite functional abnormalities with a set of low-cost procedures that are easy to perform and widely available, entail a low radiation burden, closely reflect the physiology of the tract under evaluation, are well tolerated and require minimum cooperation by patients, and provide quantitative data for better intersubject comparison and for monitoring response to therapy. Despite the relatively low degree of standardization both in the scintigraphic technique per se and in image processing, these methods have shown excellent diagnostic performance in several function or motility disorders of the upper digestive tract. Dynamic scintigraphy with a radioactive liquid or semisolid bolus provides important information on both the oropharyngeal and the esophageal phases of swallowing, thus representing a useful complement or even a valid alternative to conventional invasive tests (such as stationary esophageal manometry) for evaluating abnormalities of oropharyngoesophageal transit. Clinical applications of esophageal transit scintigraphy include disorders such as nutcracker esophagus, esophageal spasm, noncardiac chest pain of presumed esophageal origin, achalasia, esophageal involvement of scleroderma, and gastroesophageal reflux and monitoring of response to therapy (either medical or surgical treatment of disease-for example, organic disease such as esophageal cancer). Scintigraphy with a radiolabeled test meal represents the gold standard for evaluating gastric emptying, whereas more recent radionuclide methods include dynamic antral scintigraphy and gastric SPECT for assessing gastric accommodation. Clinical applications of gastric-emptying scintigraphy include, among others, evaluation of patients with dyspepsia and evaluation of gastric function in various systemic diseases affecting gastric emptying. The present review includes the proposal of clinical algorithms for evaluating patients with the main disorders of the upper digestive tract. These algorithms, originally derived from available literature, have been developed on the basis of a vast clinical experience in conjunction with the specialists more deeply involved in the care of patients with such disorders (medical and surgical gastroenterologists and nuclear medicine physicians). The role of radionuclide gastroesophageal motor studies is clearly identified in the various steps of patients' management, from the initial diagnostic approach to functional characterization to postoperative follow-up or monitoring of medical therapy.

[Esophageal function remains unchanged in systemic sclerosis at four years of follow-up].

AIM: Esophageal involvement is one of the earliest gastrointestinal manifestations of systemic sclerosis. Reduced lower esophageal sphincter pressure and reduced esophageal motility can both be measured by manometry. METHODS: 15 patients with systemic sclerosis (6 with altered manometric values and 9 with symptoms of pyrosis and/or dysphagia but with normal manometric values) were reassessed after a follow-up period of over 46 months. RESULTS: Low though still within normal range values in lower esophageal pressure were found on manometry. Distal esophageal amplitude remained substantially unchanged. Only in one patient was the amplitude significantly reduced. In all patients, the symptom scores for pyrosis and dysphagia had worsened slightly. CONCLUSIONS: Esophageal involvement does not necessarily occur in all patients with systemic sclerosis; more time may be required before its manifestations can be assessed by esophageal manometry.

[Constipation: Initial evaluation and diagnostic approach].

Constipation is a common gastrointestinal symptom and affects about 20% of the general population. This symptom can reflect a vast array of problems, from inadequate fiber intake to colonic dismotility function. Identifying chronic constipation subtypes on underlying physiology guides the therapeutic choices. Chronic constipation subtypes includes: slow-transit constipation, functional constipation, irritable bowel syndrome with constipation predominance and pelvic floor dysfunction. The most useful tests for the evaluation of those patients are the colonic transit time with radiopaque markers and anorrectal manometry with balloon expulsion test. Patients with both normal tests have either functional constipation or irritable bowel syndrome with constipation. Subjects with a delayed colonic transit and normal anorectal manometry maybe classified as colonic inertia. Pelvic floor dysfunction maybe suspected if the patient had an abnormal manometry with failure to expulse de balloon. Initial treatments of chronic constipation are dietary fiber and medicinal bulk. Subsequent treatments if fiber is not successful or tolerated would include saline osmotic laxatives such as lactulose and polyethylene glycol, or stimulants like senna or bisacodyl. For patients with pelvic floor dyssynergia biofeedback therapy is the first therapeutic option. In this article we present an overview of current diagnostic tools for patients with chronic constipation.

[Diagnosis and treatment of pediatric anismus].

OBJECTIVE: To explore the diagnosis and treatment methods of pediatric anismus. METHODS: Twenty-nine patients with idiopathic chronic constipation, diagnosed with anismus by colon barium contrast and anorectal manometry from Nov. 2001 to Nov. 2004 in our hospital, were investigated retrospectively. RESULTS: This group consisted of 13 men and 16 women whose mean age was (6.7+/-4.0) years. Hirschsprung diseases were excluded from the patients by colon barium contrast and rectoanal inhibitory reflex (RAIR) examination. Normal RAIR (5-10 ml elicited) was showed on 21 cases while weakened RAIR (15-30 ml elicited) was showed on 8 cases. After the diagnosis, the patients were treated by toilet training, diet regulation and laxative for 1-2 months. 4 cases were recovered, 5 cases were improved and 20 cases were relied on glycerin suppository. Four cases, relied on glycerin suppository, underwent Lynn procedure and had good results after 5-24 months follow-up. Two cases were re-examined by anorectal manometry 3 and 6 months after surgery, the resting pressure and the high pressure zone (HPZ) decreased, but the simulation defecation reflex was still abnormal. CONCLUSIONS: The diagnosis of pediatric anismus relies on history of constipation, combined with anorectal manometry and colon barium contrast. Lynn procedure could be chosen for the patients unsatisfied in toilet training and other non-operative treatment.

Abdominal and pelvic stop-flow chemotherapy. Effect of chemotherapeutic agents and tissue ischemia on rectoanal pressures.

In hypoxic stop-flow chemoperfusion high doses of chemotherapeutic agents are almost directly administered to locally advanced tumors without risking significant systemic toxicity, although chemotherapy-induced neurotoxicity is still a problem. The aim of the study was to assess rectoanal motility and sensation before, during and after abdominal and pelvic stop-flow chemotherapy using the methods of stationary and ambulatory manometry. Stationary rectoanal manometry was performed within 24 hrs before and repeated 48 hrs after stop-flow chemotherapy in 7 consecutive patients with a history of locally advanced or recurrent abdominal and pelvic tumors. Anal sphincter resting and squeeze pressures, rectal sensitivity, rectoanal inhibitory reflex and rectal volumes at which temporary and permanent urge to defecate were reported were examined. Rectal volume associated with leak of rectal contents and rectal compliance were also assessed. Intraoperatively, changes in rectal and anal resting pressures before, during and after occlusion of the vessels and after administration of chemotherapeutic agent were as well recorded, analyzed and interpreted using ambulatory manometry. Induction of anesthesia reduced distal and proximal anal resting pressures. Vascular occlusion further and dramatically decreased resting pressures at all levels, which were fully recovered after re-establishing local blood circulation and for the rest of the recording period. Intraoperative administration of chemotherapy did not further affect anal resting pressures during or after hypoxia. No significant changes in rectoanal motility and sensation were detected on the 48 hrs postoperative assessment as compared to the preoperative state. Tissue hypoxia induced by vascular occlusion during stop-flow chemotherapy procedure, seems to be the only factor leading to a dramatic drop of anal pressures. Anal pressures fully recover after reperfusion of the isolated area. Furthermore, anorectal motility and sensation are not affected by any direct or indirect toxic action of the chemotherapeutic agents.

Late functional adaptation after colectomy, mucosal proctectomy, and ileal pouch-anal anastomosis.

Ileal pouch-anal anastomosis (IPAA) is currently an alternative to proctocolectomy and ileostomy for patients with ulcerative colitis or familial polyposis. Some studies have suggested significant anal sphincter damage after mucosal proctectomy. Our aim was to assess prospectively late sphincter function after IPAA. In 250 patients, anorectal pressures were assessed with a pneumohydraulic perfused catheter manometry system. Each patient underwent colectomy, mucosal proctectomy, ileoanal anastomosis of a 15 cm ileal J-pouch, and loop ileostomy. Eight weeks after IPAA, anal manometry was repeated, and the ileostomy was closed. Manometry was repeated at yearly intervals. A decline in resting tone of the anal sphincter occurred early after IPAA with a gradual recovery toward control. External sphincter squeeze after pressures were not affected by IPAA and steadily increased to 8 years after operation. During this time, a progressive increase in J-pouch capacity was noted, and 24-hour stool frequency declined from 7.9 +/- 0.3 stools to 6.5 +/- 0.3 stools (p less than 0.05). We conclude that mucosal proctectomy results in internal anal sphincter trauma but is associated with long-term sphincter recovery, coupled with a significant improvement in external sphincter capacity, ileal pouch volume, and stool frequency.

Stasis syndromes following gastric surgery: clinical and motility features of 60 symptomatic patients.

We retrospectively reviewed the records of 60 patients who had been referred for gastrointestinal manometry because of stasis after gastric surgery. Nausea, vomiting, bloating, abdominal pain, and weight loss were the most common symptoms. Two thirds of these patients had a well-documented history of peptic ulcer before their initial operations; in others, surgery was performed for other reasons, such as obesity (5%) or reflux esophagitis (8%). Twelve patients had undergone truncal vagotomy and a "drainage operation" and 48 had received a partial gastrectomy with a gastroenterostomy: Billroth I (n = 8), Billroth II (n = 11), Roux-en-Y (n = 29). All patients had recordings of gastrointestinal manometry; 16 also had a scintigraphic measurement of gastric emptying. Measurements were compared with data from healthy controls. Gastric manometry, which could be assessed only in the group with an intact antrum, was characterized by antral hypomotility (p less than 0.05). Gastric emptying studies showed rapid early emptying of liquids and delayed emptying of solids (both p less than 0.05). In the whole group, fasting jejunal motility was characterized by absence of phase II in 13, presence of bursts of phasic activity in 18, and abnormal propagation of phase III in 8. A significantly increased frequency of phase III of MMC was noted in the patients after Billroth II and Roux-en-Y operations. Postprandially, 19 patients failed to develop a "fed pattern."(ABSTRACT TRUNCATED AT 250 WORDS)

Inaccuracy of Doppler estimates of pulmonary artery pressure using pulmonary flow acceleration time.

Pulsed Doppler echocardiography was used to estimate mean pulmonary artery pressure (PAP), mean pulmonary artery wedge pressure PAWP) and the changes in PAP and PAWP following intervention in an unselected population composed of 60 patients undergoing routine diagnostic cardiac catheterization. Simultaneous Doppler and strain gauge manometry recordings of PAP and PAWP were interpreted by independent observers in a blinded fashion. A first set of measurements was obtained before left ventricular angiography and a second soon after the injection of contrast dye. The mean Doppler PAP and PAWP were derived from acceleration time and calculated using previously published regression equations: PAP = -0.45 x AcT + 79, PAWP = 57 - 0.39 x AcT. At rest, PAP measurements by strain gauge manometry ranged from 13 to 45 mmHg with a mean of 24 +/- 10 (one standard deviation); PAWP ranged from 2 to 40 mmHg with a mean of 15 +/- 6. Following left ventricular angiography, the PAP ranged from 18 to 50 mmHg with a mean of 29 +/- 7; PAWP ranged from 6 to 45 mmHg with a mean of 20 +/- 7. The values obtained by pulsed Doppler before and after intervention correlated poorly with those obtained by strain gauge manometry (r = 0.09 and 0.26 for PAP; r = 0.03 and 0.25 for PAWP).(ABSTRACT TRUNCATED AT 250 WORDS)

[A modified Hill's procedure in the surgical treatment of hiatal hernia].

After an introduction on the problems regarding indications and surgical management of gastro-oesophageal reflux disease, the Authors describe the technique they use, which is a modification of Hill's posterior gastropexy, involving the placement of suture through the median arcuate ligament, without exposing the celiac axis. The preliminary results of a prospective randomized clinical trial, conducted at the Surgical Clinic Department of Catholic University, Rome, are described. The trial evaluated early and late results of Hill's modified technique versus a control group, in which a Dor technique has been used. Intraoperative oesophageal manometry has been performed in both groups, to set the cardioplasty more properly. Ninety-one patients out of 132 have been studied; 65 had a good response to medical therapy and 26 have been operated upon. In 9 cases (6 Dor and 3 Hill) intraoperative manometry was performed. All patients have been studied pre-operatively with upper g.i. series, endoscopy with biopsies, oesophageal manometry and 24-h pH monitoring; this protocol has been repeated after 3 to 6 months postoperatively, to evaluate the results more accurately. The preliminary data, although statistically non significant because of the small study group, seem to favour the Hill modified technique, both for complication and reflux control. Further data are needed to confirm them.

[Sphincter rupture in the course of labor].

Thirty-eight women with anal sphincter rupture during childbirth were followed for three to 12 months. Fourteen patients presented with continence disturbances, nine to solid or fluid faeces and five to gas. Incontinence was present in nine patients three months after childbirth. Anal manometry and anal electromyography were performed on the patients three to five days after delivery and repeated at three, six and twelve months after childbirth. Manometry and electromyography were performed on 16 control subjects and 24 primiparous control patients who were investigated three to five days and three months after delivery. Anal manometry and anal electromyography showed significant differences between both incontinent and continent patients compared to control subjects and primiparous control patients. Primiparous control patients had decreased squeeze pressure as well as decreased electromyographic activity during the first days after delivery compared to control subjects. After three months no differences were found. Continence disturbances are frequent after sphincter rupture and these patients should be monitored after delivery and those with persisting incontinence offered sphincter repair.

[Chronic constipation. Use of cisapride].

We studied the effect of Cisapride (10 mg vo every 8 hours) on the characteristics of the evacuations, orocoecal transit time and motility trough rectoanal manometry in patients diagnosed with chronic constipation. The patients (N = 51) received placebo and/or drug in a controlled, randomized, double blind, crossed study during two treatment phases of 30 days each. The end of each phase was followed by a clinical evaluation, a rectoanal manometry and hydrogen breath test. Cisapride increased the rhythm of ecacuations (5.53 days +/- 3.11 vs 1.59 days +/- 1.15 p < 0.05) improved the frequency of evacuations and diminished the consistency of the feces (p < 0.05), shortened the orocoecal transit time (271.57 min +/- 9.87 vs 201.18 min +/- 29.30 p < 0.05) and improved the parameters of the rectoanal manometry readings such as the pressure of internal anal sphincter (58.14 mmHg 7.33 vs 53.90 mmHg 5.19 p < 0.05), and its relaxation percentage (73.41% +/- 15.30 vs 66.84% +/- 11.83 p < 0.05). Side effects associated with Cisapride were not significant. It is concluded that Cisapride improves intestinal motility in chronic constipation.

[Heller's intervention for esophageal achalasia].

From 1962 to 1992 sixtythree patients with esophageal achalasia underwent primary surgical treatment. The intervention performed was a cardiomiotomy according to Heller in 20 patients (Group A), a cardiomiotomy according to Heller with anti-reflux procedure according to Lortat-Jacob in 12 patients (Group B), a cardiomiotomy according to Heller with fundoplicatio according to Dor in 31 patients (Group C). Preoperative study was performed by radiological evaluation in patients of Group A, while patients of Group B and Group C were submitted also to endoscopy and esophageal manometry. Postoperative evaluation in Group A was performed by clinical and endoscopical controls, while in Groups B and C by clinical and radiological studies 6 months after the intervention and by clinical and endoscopical studies every two years. During the early two years after operation a functional study (esophageal manometry and esophagogastric pH-monitoring) was performed. The follow-up was complete for 13 patients of Group A, 10 patients of Group B and 28 patients of Group C. Good results (complete absence or slight dysphagia) have been obtained in 70% of Group A, in 90% of Group B and 90% of Group C. Esophageal manometry found a decrease of both resting pressure and length in every patient in Groups B and C. Gastro-esophageal reflux symptoms were found in 15% of Group A, 20% of Group B and 11% of Group C. A various degree of esophagitis was found by endoscopy in 40% of Group A, 50% of Group B and 18% of Group C. Esophago-gastric pH-monitoring, performed in Group C patients, showed pathologic refluxes in 22% of the subjects. The clinical and functional study demonstrates that Heller's cardiomiotomy, in the way it is performed nowadays (complete miotomy over 7 cm of the esophagus and 3-4 cm of the stomach), allows the complete disappearance of dysphagia. On the other side the anti-reflux procedures till now performed (including the 180 degrees fundoplicatio according to Dor) are not effective enough to avoid post-operative gastro-esophageal reflux.

Dysphagia lusorum in children.

The association of difficulty in swallowing and an aberrant right subclavian artery is termed dysphagia lusorum. Dysphagia lusorum has been reported not to occur in children. We describe four children who had difficulty swallowing and aberrant right subclavian arteries. Esophageal manometry showed high pulsatile pressure in the area of the aberrant right subclavian artery in each child (12 to 100 mm Hg). Three of the four children underwent surgical correction, and their symptoms resolved. Postoperatively, esophageal manometric findings were normal. We conclude that dysphagia lusorum occurs in children and esophageal manometry shows persistently increased intraesophageal pressure, causing a functional partial obstruction in symptomatic children with dysphagia lusorum.

Symptoms are a poor indicator of reflux status after fundoplication for gastroesophageal reflux disease: role of esophageal functions tests.

BACKGROUND: If a patient develops foregut symptoms after a fundoplication, it is assumed that the operation has failed, and acid-reducing medications are often prescribed. Esophageal function tests (manometry and pH monitoring) are seldom performed early in the management of these patients. HYPOTHESIS: In patients who are symptomatic after fundoplication for gastroesophageal reflux disease, a symptom-based diagnosis is not accurate, and esophageal function tests should be performed routinely before starting acid-reducing medications. DESIGN: Prospective study. SETTING: University hospital. PATIENTS AND METHODS: One hundred twenty-four patients who developed foregut symptoms after laparoscopic fundoplication (average, 17 months postoperatively) underwent esophageal manometry and pH monitoring. Sixty-two patients (50%) were taking acid-reducing medications. MAIN OUTCOME MEASURES: Postoperative symptoms, use of antireflux medications, grade of esophagitis, esophageal motility, and DeMeester scores. RESULTS: Seventy-six (61%) of the 124 patients had normal esophageal acid exposure, while the acid exposure was abnormal in 48 patients (39%). Only 20 (32%) of the 62 patients who were taking acid-reducing medications had reflux postoperatively. Regurgitation was the only symptom that predicted abnormal reflux. CONCLUSIONS: These results show that (1) symptoms were due to reflux in 39% of patients only; (2) with the exception of regurgitation, symptoms were an unreliable index of the presence of reflux; and (3) 68% of patients who were taking acid-reducing medications postoperatively had a normal reflux status. Esophageal function tests should be performed early in the evaluation of patients after fundoplication to avoid improper and costly medical therapy.
