Outcomes of fundoplication in children with cystic fibrosis

Purpose Children with cystic fibrosis (CF) have a high prevalence of gastroesophageal reflux disease (GERD). As GERD is associated with chronic respiratory symptoms and feeding problems, fundoplication is often performed in children with CF. Although the outcomes of fundoplication have been described across diverse pediatric groups, there is no published experience with CF. Methods The records of 25 children with CF who underwent fundoplication in our center were reviewed. Data on symptoms and diagnostic testing results as well as on complications related to fundoplication were collected. Nutritional parameters and pulmonary function were compared before and after fundoplication. Results There was no mortality associated with fundoplication, but 12% had complications that required a subsequent surgical procedure. Whereas 28% were able to discontinue their antireflux medications, 48% developed symptoms of recurrent GERD. Overall, there was no change in body mass index, body mass index percentile, or the slope of forced expiratory volume in 1 second (FEV 1) after fundoplication. Children who had an FEV 1 of less than 60% predicted at the time of fundoplication exhibited an improvement in FEV 1 slope compared to those with FEV 1 of 60% or more (+5.3% vs −8.6% per year, P = .004). Conclusion The complication rate of fundoplication is similar to what has been reported in large series in children without CF. There is a high rate of recurrent GERD and little apparent benefit for either nutritional or pulmonary outcomes. The observed difference on FEV 1 slope, in those with moderate-severe vs mild lung disease, highlights the need to thoroughly evaluate the role of fundoplication in children with CF.

Radiofrequency energy delivery to the lower esophageal sphincter (Stretta procedure) in patients with recurrent reflux after antireflux surgery

Recurrent reflux following antireflux surgery (ARS) can be difficult to manage, especially in patients who also fail medical management. In these patients, redo ARS remains the only treatment option. Endoscopic radiofrequency energy delivery to the lower esophageal sphincter (the Stretta procedure; Stretta, Curon, Sunnyvale, CA) has been shown to significantly decreased symptom scores and improve quality of life in patients with gastroesophageal reflux disease (GERD). The aim of this study was to evaluate the use of the Stretta procedure in treating patients with recurrent reflux after fundoplication. Between March 2002 and December 2003, eight patients with recurrent reflux following ARS underwent the Stretta procedure. All patients were asked to complete an institutional symptom survey pre-Stretta and at 1, 6, and 12 months after the procedure. Patients rated 7 reflux-related symptoms (heartburn, dysphagia, regurgitation, cough, voice changes/hoarseness, asthma, chest pain) on a 0 (none) to 3 (severe) scale. Data were analyzed using a Wilcoxon matched pairs signed rank test where appropriate. Complete data were obtained for seven of the eight patients, with a median follow-up of 253 days (range, 67-378 days). One patient was lost to follow-up and not included in our analysis. Symptom scores decreased significantly, with six patients noting both improved typical and atypical symptoms. Overall, six patients (85%) were satisfied with their results. Based on this small series, the Stretta procedure significantly reduces subjective symptoms of GERD. The Stretta procedure may serve an important role as an additional management strategy to help manage recurrent GERD after ARS.

Anatomic findings and outcomes after antireflux procedures in morbidly obese patients undergoing laparoscopic conversion to Roux-en- Y gastric bypass

Background To report the anatomic findings and outcomes in patients undergoing laparoscopic takedown of Nissen fundoplication with conversion to Roux-en- Y gastric bypass. Methods We reviewed the records of patients who underwent laparoscopic Nissen takedown with conversion to Roux-en- Y gastric bypass from January 2001 to April 2006 at the University of Minnesota Medical Center. Results Eleven patients were identified. Nine patients had gastroesophageal reflux disease preoperatively, of whom six underwent 24-hour pH monitoring. In 2 patients, the pH study findings were negative. Eight prior procedures had been performed laparoscopically. Eight patients were women. The mean age was 44 years. The average body mass index preoperatively was 44 kg/m 2 (range 35–61). The mean follow-up was 13.8 months (range 4–39). The body mass index at follow-up was 30.2 kg/m 2. The operative time was 349 minutes (range 222–624). The hospital length of stay was 3.4 days (range 2–6). No conversions to open surgery were required. No major short-term complications developed. Minor complications included wound or drain site infection in 3 patients, with abscess in 2, pressure sore of the lateral aspect of the foot in 1, pneumonia in 2, and marginal ulcer in 2 patients. No strictures were observed. One internal hernia occurred. Of the 9 patients with gastroesophageal reflux disease preoperatively, all had 100% improvement in symptoms, with complete resolution in 7 (78%). Wrap disruption was present in 5 (45%) of 11 patients. Herniation of an intact wrap had occurred in 1 patient. One patient had both herniation and wrap disruption. Conclusion Laparoscopic conversion of Nissen fundoplication to Roux-en- Y gastric bypass is a feasible salvage operation for recurrent gastroesophageal reflux disease in the morbidly obese. The incidence of wrap disruption appears to be relatively high and the incidence of intact wrap herniation low in obese patients after failed Nissen fundoplication, suggesting that the mechanism of failure after primary antireflux surgery in obese patients may be different than that in normal-weight patients.

Laparoscopic treatment of Barrett’s esophagus: long-term results

Gastroesophageal reflux disease (GERD) is considered the main etiologic process in the metaplastic development of Barrett's esophagus (BE). The most serious complication of BE is the possible dysplastic evolution to esophageal carcinoma. Many treatments have been described to prevent the progression of BE. The outcomes of these interventions are controversial. The aim of this study was to assess whether laparoscopic fundoplication for GERD had an impact on the development of BE. Prospective data were collected from patients who were treated with a laparoscopic fundoplication for BE. Data was collected and analyzed for a variety of clinical and pathologic outcomes. Laparoscopic fundoplications were completed between 1993 and 2001, with a total sample size of 92 (mean age 53 +/- 11.8 years). Each patient was diagnosed with GERD associated with BE confirmed by both endoscopy and biopsy. A laparoscopic fundoplication was performed in all patients (360 degree fundoplication in 81 patients and partial fundoplication in 11 patients). There was no postoperative mortality or major complications from the procedure. The mean postoperative stay was 3 +/- 1 days. Seventy patients (76% of the overall sample size) were followed up for a mean 4.2 +/- 2.6 years. Of the patients available for follow-up, 33% (n = 23) had a complete regression of their BE; 21% (n = 15) had a decrease in the degree of metaplasia/dysplasia; 39% (n = 27) had no significant change; and 7% (n = 5) experienced a progression of the BE. Five patients required further procedures for three reasons: (1) GERD recurrence (n = 2), (2) progression of BE (n = 2), and (3) intrathoracic migration (n = 1). No patients developed high-grade dysplasia or esophageal carcinoma. The results of this study suggest that laparoscopic fundoplication offers a safe and effective long-term treatment for BE. The procedure also demonstrated regression of BE in more than 50% of the sample size.

Laparoscopic redo Nissen fundoplication in infants and children

From January 1994 to December 2004, 118 patients with recurrent gastroesophageal reflux disease (GERD) after fundoplication underwent laparoscopic redo Nissen fundoplication. The patients ranged in age from 6 months to 19 years (mean, 7 years), and weighed from 6.4 to 85 kg. Of the 118 patients, 64 had previous open fundoplications, 53 had previous laparoscopic fundoplications, and 19 had more than one previous fundoplication. All the procedures had been successfully completed laparoscopically. The average operative time was 100 min. The intraoperative complication rate was 1.1%. The average time to full feeding was 1.8 days, and the average hospital stay was 2.2 days. The postoperative complication rate was 3.6%. The wrap failure rate during an average follow-up period of 48 months was 6%. Laparoscopic redo Nissen fundoplication for a failed antireflux procedure is a safe and effective procedure. It has the same benefits as a primary laparoscopic Nissen for GERD, with low morbidity and a quicker recovery. Early follow-up evaluation suggests that the long-term outcome is superior to that associated with open redo fundoplication.

Quality of Life in GERD Patients: Medical Treatment Versus Antireflux Surgery

Medical and surgical treatments are able to improve symptoms in patients with gastroesophageal reflux disease (GERD). The aim of this study was to evaluate the outcome in GERD patients without therapy, under continuous medical treatment, and after laparoscopic antireflux surgery. Five hundred seventy-nine consecutive patients underwent medical or surgical treatment for GERD-induced symptoms. Patients were studied in detail before and after treatment by means of a symptom questionnaire, endoscopy, esophageal manometry, 24-hour esophageal pH monitoring, and a barium esophagogram. In addition, quality of life was measured by the means of the Gastrointestinal Quality of Life Index (GIQLI) and the Health-Related Quality of Life (HRQL) questionnaire. Surgery was indicated and performed in 351 patients with persistent or recurrent GERD symptoms and/or complications, and in patients preferring surgery to medical treatment, despite the use of an adequate medication. The remaining 228 patients were treated with proton pump inhibitors (PPI) in the standard dose, or if required, the double dose. The outcome was assessed 3 and 12 months after treatment. While symptoms and quality of life were highly impaired in GERD patients without therapy compared with normal people, a significant improvement was obtained by PPI therapy. Following surgery, quality of life was normalized in all subsections and was significantly higher compared with the medically treated group. These results stayed constant in short-term and intermediate follow-up. Medical and surgical therapies are both able to improve symptoms and quality of life in GERD patients. Nevertheless, the outcome is significantly better following surgery. It can be suggested that surgical treatment may be the more successful therapy in the long-term.

Failed Antireflux Surgery: Results After Reoperation

Since laparoscopy has become a common surgical approach for antireflux surgery, little is known regarding reoperation for failed antireflux surgery. Records of all patients who underwent reoperation without esophageal resection for symptoms of recurrent gastroesophageal reflux disease or hiatal hernia between July 1, 1995 and April 1, 2004 were reviewed. There were 126 patients. Two patients declined research participation. The remaining 124 patients (71 women and 53 men) formed the basis for this study. Median age was 53 years (range, 19 to 83 years). The initial operation was a laparoscopic antireflux procedure in 76 patients (61.3%) and an open repair in 48 (38.7%). A single previous operation had been done in 100 patients, two operations in 20, and three operations in 4. The median interval between the most recent reoperation and the previous operation was 28 months. All patients were symptomatic. The surgical approach was a thoracotomy in 83 patients, laparotomy in 36, laparoscopy in 4, and thoracoabdominal in 1. A Nissen fundoplication was performed in 86 patients (69.4%), Belsey fundoplication in 31(25.0%), and others in 7. There were no operative deaths. Complications occurred in 27 patients (21.7%). Median hospitalization was 6 days (range, 5 to 58 days). Follow-up ranged from 10 days to 10 years (median, 9.7 months). Improvement was observed in 114 patients (91.9%). Functional results were classified as excellent in 69 patients (55.6%), good in 19 (15.4%), fair in 26 (20.9%), and poor in 10 (8.1%). No single operative approach was functionally superior. We conclude that reoperation for failed antireflux surgery is safe and effective. Results of reoperation were not affected by the type of reoperation or whether the previous approach was laparoscopic or open.

Effect of pregnancy on effectiveness of laparoscopic Nissen fundoplication

Symptoms of gastroesophageal reflux disease (GERD) are experienced by up to 85% of pregnant women. Some young women on maintenance proton pump inhibitor (PPI) treatment are choosing surgery to stop their medical treatment and avoid severe symptoms during pregnancy. There are no reports describing the effect of pregnancy on the long-term efficacy of laparoscopic Nissen fundoplication. The aim of this study was to evaluate the effect of pregnancy on the efficacy of laparoscopic Nissen fundoplication. This study surveyed 146 women of childbearing age with proven GERD who had undergone laparoscopic Nissen fundoplication from 1992 through 2002. The patients who became pregnant (group 1) were compared with those who did not (group 2). The study focused on 25 patients who became pregnant after surgery. Of these patients, 40% (n = 10) had chosen surgery as a way to discontinue PPI treatment before pregnancy. The mean time from laparoscopic Nissen fundoplication to pregnancy was 25.9 +/- 4.6 months. A total of 19 patients (76%) had no reflux symptoms, whereas 5 (20%) required antacids during pregnancy. One patient (4%) experienced an acute intrathoracic stomach migration during her pregnancy and required emergency open surgery, which resulted in the loss of her fetus. After pregnancy, six patients (24%) had recurrence of GERD symptoms, and three (12%) required a redo fundoplication. The higher rate of GERD recurrence (24% vs 16.7%) and redo surgery (12% vs 4%) in group 1 did not reach statistical significance, but showed a definite trend. For most patients, laparoscopic Nissen fundoplication is effective in controlling GERD symptoms during and after pregnancy.

Laparoscopic Nissen fundoplication without division of short gastric vessels in children

Purpose It has been suggested that routine division of short gastric vessels (SGVs) results in a more “floppy” Nissen fundoplication leading to improved outcomes, that is, less dysphagia and lower incidences of recurrent gastroesophageal reflux disease (GERD). The aim of this retrospective study was to assess whether laparoscopic Nissen fundoplication without division of SGVs (Rossetti modification) (laparoscopic Nissen-Rossetti fundoplication [LNRF]) is associated with acceptable clinical outcome in children. Method The charts of 368 children who underwent LNRF between January 1996 and September 2004 by 1 primary surgeon were retrospectively reviewed. Children were divided into 2 groups: LNRF + gastrostomy (A) and LNRF alone (B). Mean follow-up period of all groups was 4.2 years. Results Laparoscopic Nissen-Rossetti fundoplication was completed in 99% (365/368). Mean operating time for group A was 74 minutes and 61 minutes for group B. None in group A required postoperative esophageal dilatation, and 9 in group B (22.5%) required 12 dilatations; 3.6% developed recurrent GERD, 3.7% in group A and 2.5% in group B. Conclusion Laparoscopic Nissen-Rossetti fundoplication can be performed with acceptable long-term outcome in children, especially in the majority also requiring chronic gastrostomy access. Short-term, reversible dysphagia may be seen in a small percentage of children having fundoplication alone.

Gastrointestinal complications of fundoplication

In children with medically refractory gastroesophageal reflux disease (GERD), fundoplication is effective and safe. However, in a subset of patients, gastrointestinal dysfunction occurs postoperatively. Symptoms include chest pain, persistent dysphagia in 5%, gas bloat in 2% to 4%, diarrhea in up to 20%, and dumping syndrome in up to 30%. Symptoms are often nonspecific, arising from recurrent or persistent GERD, anatomic complications such as disrupted or herniated wrap, functional disturbances such as rapid gastric emptying or altered gastric accommodation, or alternative diagnoses such as cyclic vomiting syndrome or food allergy. Detailed investigation, including various combinations of pHmetry, videofluoroscopy, endoscopy, motility studies, and dumping provocation testing, may be required to clarify pathophysiology and guide management.

Outcomes of surgical fundoplication in children

Surgical fundoplication has been recommended for children with persistent GERD. The purpose of this study was to determine the frequency of postoperative symptoms requiring medical evaluation and/or treatment after fundoplication in children with or without associated medical disorders. In a retrospective cohort study, we reviewed the medical records of all children who underwent fundoplication during 1996-1999. Data were collected to analyze the following: (1) postoperative complications, (2) postoperative symptoms, (3) procedures performed to evaluate postoperative symptoms, (4) medical treatment, and (5) repeat surgery. A total of 198 children underwent fundoplication, and 176 (89%) came for follow-up evaluation within 2 months after surgery. The median age at the time of surgery was 2.1 y (range, 6 mo-18 y) and the median duration of follow-up was 2.0 y (range, 1.2-4.8 y). A total of 130 (74%) children had one or more associated medical disorders including neurodevelopmental delay (70%), cystic fibrosis (8%), tracheoesophageal anomalies (8%), bronchopulmonary dysplasia (8%), and reactive airway disease (35%). Postoperatively, children with associated medical disorders had a higher frequency of lung infections (52% vs. 22%, P = .03) and dumping syndrome (2% vs. 0%, P = .05). Most children (63%) received evaluation and treatment for symptoms suggestive of recurrent reflux despite fundoplication. Nearly two thirds of children who received fundoplication and were followed-up within 2 months after surgery either have symptoms or receive medical therapy for reflux. Fundoplication for the control of GERD in children needs further evaluation.

Laparoscopic Gastric Bypass after Antireflux Surgery for the Treatment of Gastroesophageal Reflux in Morbidly Obese Patients: Initial Experience

Laparoscopic Roux-en-Y gastric bypass (LRYGBP) has been proven effective against gastroesophageal reflux disease (GERD) in morbidly obese patients. We present our experience with revision of antireflux procedures to LRYGBP in obese patients with recurrent GERD, weight gain or a combination of both and discuss the indications and technical considerations involved. Between June 2000 and December 2003, 7 morbidly obese patients with a mean BMI of 37.5 kg/m(2) underwent revision of an antireflux procedure to LRYGBP by our group. Important steps of the revision include dissection of the diaphragmatic crura and gastroesophageal fat pad, reduction and repair of hiatal hernia, and complete take-down of the wrap to avoid stapling over the fundoplication which can create an obstructed, septated pouch. Mean operative time was 6 hr 12 min and length of stay was 4.8 days. There were 3 major complications postoperatively and no deaths. During follow-up, 5 patients developed anastomotic strictures and 2 patients were re-explored for gastric remnant herniation and intestinal obstruction. At a mean follow-up of 24 (3-44) months, mean excess weight loss was 70.7% and 14/20 (70%) co-morbid conditions were improved or resolved. GERD evaluation with the GERD-HRQL scale showed a significant reduction of GERD scores postoperatively (P =0.006). Although LRYGBP after antireflux surgery is a technically more difficult procedure with a higher morbidity, it is feasible and effective for the treatment of recurrent GERD and worsening obesity with the additional advantage of weight loss and improvement of co-morbidities.

Late laparoscopic reoperation of failed antireflux procedures.

Failures of antireflux procedures occur in 5% to 10% of the patients. Our objective is to report our experience with laparoscopic management of failed antireflux operations. Of 1698 patients who underwent laparoscopic treatment of gastroesophageal reflux disease (GERD), 53 were reoperations following either a previous open or laparoscopic antireflux procedure. The indications for surgical reoperation were persistent or recurrent GERD in 35 patients (66%), presence of paraesophageal hiatal hernia in 4 (7.5%), and severe dysphagia in 14 (26.4%). Hospital stay varied from 1 to 8 days, with an average of 1.2 days. Conversion to open laparotomy occurred in 10 patients (18.8%). The main causes for persistent or recurrent GERD were herniation (n=20) and disruption (n=12) of the fundoplication. Two patients had both herniation and disruption of the fundoplication. The main reason for severe dysphagia was tight hiatus. The most common reoperations were hiatal repair for hernia correction (n=26), redo fundoplication (n=16), and widening of the hiatus (n=12). Two patients had both hiatal repair and redo fundoplication. Intra (n=5) and postoperative (n=16) complications were frequent, but they were usually minor. There was no mortality. The present study demonstrated that laparoscopic reoperation for failed antireflux procedures may be performed safely in most patients with excellent result, low severe morbidity, and no mortality.

Use of radiofrequency ablation of the lower esophageal sphincter to treat recurrent gastroesophageal reflux disease

Purpose Recurrent gastroesophageal reflux disease (GERD) after gastroesophageal surgery is a troublesome problem. Reoperative surgery often is complicated by adhesions and recurrence. Radiofrequency ablation or energy delivery (RF or the Stretta procedure) is a new method for treating GERD. This study is the first report describing the use of the Stretta procedure in pediatric patients. Methods Six patients who underwent previous gastroesophageal surgery presented with recurrent GERD. Medical records were reviewed and the severity of reflux graded using a modified scoring system. All underwent RF and were graded for GERD at 6 months postprocedure. Results Mean operating time was 80 ± 12 minutes. Mean age at initial operation was 12 ± 4 years and for the RF, 18.0 ± 3.4 years. All patients were discharged as outpatients. Early complications occurred in one child with self-resolving acute gastric distension. Five of 6 patients were completely asymptomatic at 3 months after the procedure, and 3 stopped anti secretory agents. One patient was improved but still symptomatic and needed a redo fundoplication. Another required a repeat application of RF 10 months after the initial one. Mean GERD score pre-Stretta was 5.2 ± 1.0, which improved to 1.6 ± 1.9 at 6 months postprocedure ( P < .05; paired t test). Conclusions Use of RF treatment of the lower esophageal sphincter is a potentially successful modality to treat recurrent GERD in children. Long-term follow-up is required.

Natural history of gastro-oesophageal reflux disease without oesophagitis (NERD) – a reappraisal 10 years on

Background and aim. Ten years ago we published a study describing the 6-month outcome of 33 outpatients with typical gastro-oesophageal reflux disease symptoms and pH-metry proven excess gastro-oesophageal reflux but without endoscopical evidence of oesophagitis, currently referred to as patients with gastro-oesophageal reflux disease without oesophagitis. We now present an update of that report concerning morbidity, drug consumption and quality of life of the original patients 10 years after the initial diagnosis. Methods. The study consisted of the retrieval and revision of all clinical and instrumental records concerning the cohort of 33 above-mentioned patients. Data are available regarding annual intervals within the first 5 years from original diagnosis and, subsequently, with a follow-up ranging from 7 to 14 years (median 10 years). The records of these 33 patients were reviewed, including the results of clinical visits at the outpatients department, of oesophagogastroduodenoscopies and pH- metries. Finally, a telephonic interview was conducted by means of a structured questionnaire, aiming at evaluating present symptoms, actual therapy if any, health-related quality of life and other information regarding any gastro-oesophageal reflux disease symptoms. Results. Of the original 33 patients, 31 are still alive and 2 were lost to follow-up. Of the 29 remaining, only 1 is definitively not complaining of any gastro-oesophageal reflux disease-related symptoms. Within 5 years of the first diagnosis, oesophagitis was found in all but one of the 18 subjects who underwent repeated endoscopy. At the latest follow-up check, after a median of 10 years, out of the 28 still complaining of gastro-oesophageal reflux disease symptoms, 21 (75%) were presently taking antisecretory drugs (proton pump inhibitors and H-2 receptor antagonists) because of gastro-oesophageal reflux disease symptoms/lesions, 12 of whom intermittently or on demand and the remaining 9 continuously. Two patients (2/28) underwent antireflux surgery, but despite this were still taking antisecretory drugs (in one case H2-RA; in the other proton pump inhibitor). The health-related quality of life, self-evaluated by the patient by means of a VAS scoring from 0 (worst possible) to 10 (best possible) increased significantly from 3.2 to 6.5 from baseline (before therapy) to present time, possibly due to the positive effect of present therapy. Conclusions. Our study conducted on a cohort of endoscopy-negative patients with pH-metry-confirmed reflux disease has shown that after a median time of 10 years following the original diagnosis, the majority of patients have, in fact, developed reflux oesophagitis and are on prolonged antisecretory therapy because of recurrent gastro-oesophageal reflux disease symptoms/lesions. The study confirms that gastro-oesophageal reflux disease without oesophagitis, as well as gastro-oesophageal reflux disease at large, is a chronic disease characterised by increasing severity with time, which requires protracted medical therapy in a vast proportion of patients. Absence of endoscopic oesophagitis at presentation does not represent a positive prognostic factor.

Selection of patients with gastroesophageal reflux disease for antireflux surgery based on esophageal manometry.

Gastroesophageal reflux disease (GERD) is caused by a mechanically defective lower esophageal sphincter (LES) and may be worsened by impaired esophageal peristalsis. The aim of this study was to evaluate the efficacy of medical treatment depending on the function of the LES and esophageal peristalsis. We studied 128 GERD patients with mild esophagitis. Group 1 (N = 26) consisted of patients with a normal LES and normal esophageal peristalsis. Group 2 (N = 63) comprised patients with a defective LES but normal peristalsis. Patients of group 3 (N = 39) had a defective LES as well as impaired esophageal peristalsis. The patients were continuously treated with omeprazole. Clinical evaluation and endoscopy were repeated after 3, 6, and 12 months. Recurrence of GERD was diagnosed if there was relapse of heartburn and/or esophagitis. The recurrence rate was 7.7% in group 1, 38.1% in group 2 (P < 0.05) and 79.5% in group 3 (P < 0.05). In conclusion, in GERD patients with a mechanically defective LES, especially in those with deteriorated esophageal peristalsis, antireflux surgery should be considered since medical therapy reveals a high recurrence rate.

Laparoscopic reoperation following unsuccessful antireflux surgery in childhood

We determine the feasibility of laparoscopic revision surgery in children following previous open and laparoscopic antireflux operations. To give an objective overview about this topic, we analyzed the outcome of 15 children (8 girls and 7 boys) who had undergone attempted laparoscopic revision between 4 and 72 months (median 16 months) after a previous antireflux operation. Seven patients had previously undergone an open antireflux procedure (4 Nissen fundoplication; 3 Thal procedure) and 8 a laparoscopic procedure (5 Nissen; 3 Toupet's procedure). Two of these children were mentally handicapped. The indications for revision were: recurrent reflux, 5; valve migration, 5; valve dismount, 5. Eight procedures comprised construction of a new Nissen fundoplication and in 7 cases a Toupet's procedure was performed. Revision was successfully completed laparoscopically in 10 cases, 7 of 8 patients following a previous laparoscopic procedure and in 3 of 7 following a previous open operation. Operating time ranged between 70 and 140 minutes (median 90 minutes). No perioperative complications occurred in either group. All patients were discharged within 3 to 4 days after the redo procedure. Follow-up time varied between 6 months and 7 yrs. Preoperative symptoms were relieved in all patients and all antireflux medication has been discontinued, except in two cases that still had rare symptoms. Although technically challenging, laparoscopic reoperation for recurrent gastroesophageal reflux disease can be performed safely and with good results, in the hands of experienced endoscopic surgeons. Reoperation is likely to be more difficult following failure of an open procedure than after failure of a laparoscopic one. Concerning the type of procedure, redo surgery is more difficult to perform after Nissen's than after Toupet's or Thal's procedure.

Mechanisms responsible for recurrent gastroesophageal reflux in neurologically impaired children who underwent laparoscopic Nissen fundoplication.

In this study, we attempted to define the lower esophageal sphincter (LES) motor events associated with the occurrence of gastroesophageal reflux (GER) in neurologically impaired children in whom of GER disease recurred after laparoscopic Nissen fundoplication (LNF). Of 45 neurologically impaired children who had previously undergone LNF, six children in whom recurrence of GER disease was documented by 24-h esophageal pH monitoring were studied. Concurrent esophageal manometry and pH monitoring were conducted for 1 h both before and after the administration of apple juice (10 ml/kg). A total of 89 reflux episodes were recorded in the course of the study. Of these, 51 episodes (57%) were associated with transient LES relaxation. In the remainder, reflux occurred across a contracted LES in 21 episodes (24%) and during absent basal LES tone in 15 episodes (17%). In four of six patients, transient LES relaxation was responsible for more than half of the reflux episodes. Transient LES relaxation is the predominant mechanism of reflux in neurologically impaired children with recurrent GER after LNF.

Quality of life and symptomatic outcome three to five years after laparoscopic Toupet fundoplication in gastroesophageal reflux disease patients with impaired esophageal motility

Background: Many centers practice a tailored approach to laparoscopic antireflux surgery in attempt to prevent postoperative side effects in gastroesophageal reflux disease (GERD) patients with an impaired esophageal motility. As a result of controversial findings reported in literature no worldwide accepted consensus exists regarding the appropriate indication for this tailored approach. The aim of this prospective study was to evaluate quality of life and symptomatic outcome in selected patients for a follow-up of 3 to 5 years. Methods: A total of 155 patients with esophageal dismotility underwent laparoscopic Toupet fundoplication (LTF). Basic requirements for surgery included in all patients a detailed evaluation of symptoms and quality of life (Gastrointestinal Quality of Life Index [GIQLI]), esophagogastroduodenoscopy, 24-hour pH monitoring, and esophageal manometry. Patients were evaluated 6 weeks, 3 months, 1 year, and 3 to 5 years after LTF. Results: GERD-related symptoms such as heartburn, regurgitation, dysphagia, or chest pain showed a significant improvement ( P <0.05 to 0.001) in all gradings immediately after surgery. During the complete follow-up, a total of 4 patients (2.6%) required laparoscopic redo surgery because of recurrent GERD symptoms. Two patients (1.3%) were adequately maintained on short-term proton pump inhibitor therapy because of mild symptoms. All these patients have shown a pathological DeMeester score within the early period after surgery (3 months or 1 year control). Severe and persistent side effects have been present in 7 patients (4.5%), mild to moderate side effects in 11 patients (7.1%). Other side effects have been temporary and resolved spontaneously. GIQLI improved significantly ( P <0.05 to 0.01) in all dimensions and persisted for at least 5 years with mean values comparable with healthy individuals. Conclusions: LTF is effective, well tolerated, and improves quality of life, improving long-term outcome with an acceptable rate of long-term side effects in GERD patients with moderate to severe esophageal dismotility for a follow-up period of 3 to 5 years.

Angioedema and systemic sclerosis

We report a case of chronic idiopathic recurrent urticaria-angioedema and gastroesophageal reflux disease in a 35-years-old man, followed after 2 years by Raynaud's phenomenon and esophageal dysphagia, recurrent cough and dyspnoea, and after 4 years by systemic sclerosis. A review of the literature and possible correlated pathogenetic mechanisms are presented.
