Chronic dysphagia following laparoscopic fundoplication

Nissen Versus Toupet Fundoplication For Gastro-oesophageal Reflux Disease, Short And Long-term Outcomes. A Systematic Review And Meta-analysis

BACKGROUND

Gastroesophageal reflux disease (GERD) remains one of the most commonly encountered gastrointestinal disorders. Proton pump inhibitors still show an inadequate effect on about 10% to 40% of the patients. Laparoscopic antireflux surgery is the surgical alternative for managing GERD in patients who are not responding to proton pump inhibitors.

AIM OF THE STUDY

This study objected at comparing laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication (LTF) concerning the short-term and long-term outcomes.

PATIENTS AND METHODS

This is a systematic review and meta-analysis that evaluated the studies comparing between Nissen fundoplication and LTF for the treatment of GERD. Studies were obtained by searching on the EMBASE, the Cochrane Central Register of Controlled Trials, and PubMed central database.

RESULTS

The LTF group showed significantly longer operation time, less postoperative dysphagia and gas bloating, less pressure on the lower esophageal sphincter, and higher Demeester scores. No statistically significant differences were found between the 2 groups in the perioperative complications, the recurrence of GERD, the reoperation rate, the quality of life, or the reoperation rate.

CONCLUSION

LTF is favored for the surgical treatment of GERD being of lower postoperative dysphagia and gas bloating rates. These benefits were not at the expense of significantly additional perioperative complications or surgery failure.

Efficacy of laparoscopic Toupet fundoplication compared to endoscopic and surgical procedures for GERD treatment: a randomized trials network meta-analysis

PURPOSE

We aim to review and quantitatively compare laparoscopic Toupet fundoplication (LTF), Nissen fundoplication (LNF), anterior partial fundoplication (APF), magnetic augmentation sphincter (MSA), radiofrequency ablation (RFA), transoral incisionless fundoplication (TIF), proton pump inhibitor (PPI), and placebo for the treatment of GERD. A number of meta-analyses compared the efficacy of surgical and endoscopic procedures for recalcitrant GERD, but considerable debate on the effectiveness of operative strategies remains.

METHODS

A systematic review of MEDLINE databases, EMBASE, and Web of Science for randomized controlled trials (RCTs) comparing the aforementioned surgical and endoscopic GERD treatments was performed. Risk ratio and weighted mean difference were used as pooled effect size measures, whereas 95% credible intervals (CrI) were used to assess relative inference.

RESULTS

Thirty-three RCTs were included. Surgical and endoscopic treatments have similar RR for heartburn, regurgitation, bloating. LTF has a lower RR of post-operative dysphagia when compared to APF (RR 3.3; Crl 1.4-7.1) and LNF (RR 2.5; Crl 1.3-4.4). The pooled network meta-analysis did not observe any significant improvement regarding LES pressure and pH < from baseline. LTF, APF, LNF, MSA, RFA, and TIF had have a similar post-operative PPI discontinuation rate.

CONCLUSION

LTF has a lower rate of post-operative dysphagia when compared to APF and LNF. The pre-post effects, such as GERD-HQRL, LES pressure, and pH <4, should be avoided in meta-analyses because results may be biased. Last, a consensus about the evaluation of GERD treatments' efficacy and their outcomes is needed.

A Chinese randomized prospective trial of floppy Nissen and Toupet fundoplication for gastroesophageal disease

INTRODUCTION

To evaluate the clinical outcomes of laparoscopic floppy Nissen fundoplication (LNF) and laparoscopic Toupet fundoplication (LTF) for the treatment of gastroesophageal disease (GERD).

METHODS

A total of 84 patients with GERD were randomized to either LNF (n = 43) or LTF (n = 41) between January 2010 and January 2013. The primary endpoint measures were the DeMeester score, distal esophageal amplitude (DEA), peristaltic frequency, lower esophageal sphincter pressure (LESP), short-term and long-term postoperative dysphagia and recurrence rate. The secondary endpoints were improvements in symptom scores and quality of life (QoL), and perioperative complications.

RESULTS

LNF group had a lower DeMeester score and a higher LESP compared to LTF group after surgery (DeMeester score: P = 0.007; LESP: P = 0.027). The mean DEA and peristaltic frequency both improved significantly after surgery in 2 groups. There was no difference in the incidence of short-term adverse events (including dysphagia, heartburn, regurgitation et al.) between the two groups (P = 0.157). At the time of the latest follow-up, there was no difference in the incidence of symptomatic reflux symptom (heartburn and regurgitation) between the two groups (heartburn: P = 0.363; regurgitation: P = 1.000). A higher frequency of dysphagia was present in the LNF group compared with the LTF group (P = 0.023).

DISCUSSION

LNF is associated with an excessive elevation of LESP which may lead to further persistent dysphagia. Partial fundoplication may provide adequate reflux control, improve esophageal body motility and minimize complications associated with an 'over-tight' fundal wrap.

CONCLUSION

LTF seems to be as safe and effective on the long-term as LNF, but with a lower incidence of postoperative dysphagia (ChiCTR-TRC-13003945).

Randomized controlled trial of transoral incisionless fundoplication vs. proton pump inhibitors for treatment of gastroesophageal reflux disease

OBJECTIVES

Transoral incisionless fundoplication (TIF) was developed in an attempt to create a minimally invasive endoscopic procedure that mimics antireflux surgery. The objective of this trial was to evaluate effectiveness of TIF compared with proton pump inhibition in a population consisting of gastroesophageal reflux disease (GERD) patients controlled with proton pump inhibitors (PPIs) who opted for an endoscopic intervention over lifelong drug dependence.

METHODS

Patients with chronic GERD were randomized (2:1) for TIF or continuation of PPI therapy. American Society of Anesthesiologists >2, body mass index >35 kg/m(2), hiatal hernia >2 cm, and esophageal motility disorders were exclusion criteria. Primary outcome measure was GERD-related quality of life. Secondary outcome measures were esophageal acid exposure, number of reflux episodes, PPI usage, appearance of the gastroesophageal valve, and healing of reflux esophagitis. Crossover for the PPI group was allowed after 6 months.

RESULTS

A total of 60 patients (TIF n=40, PPI n=20, mean body mass index 26 kg/m(2), 37 male) were included. At 6 months, GERD symptoms were more improved in the TIF group compared with the PPI group (P<0.001), with a similar improvement of distal esophageal acid exposure (P=0.228) compared with baseline. The pH normalization for TIF group and PPI group was 50% and 63%, respectively. All patients allocated for PPI treatment opted for crossover. At 12 months, quality of life remained improved after TIF compared with baseline (P<0.05), but no improvement in esophageal acid exposure compared with baseline was found (P=0.171) and normalization of pH was accomplished in only 29% in conjunction with deteriorated valve appearances at endoscopy and resumption of PPIs in 61%.

CONCLUSION

Although TIF resulted in an improved GERD-related quality of life and produced a short-term improvement of the antireflux barrier in a selected group of GERD patients, no long-term objective reflux control was achieved.

Effect of laparoscopic antireflux surgery on esophageal motility

BACKGROUND/AIMS

The effect of laparoscopic antireflux surgery on esophageal motility is incompletely understood, and any indication for this procedure in patients with motility disorder is disputed in literature. We evaluated the influence of laparoscopic Nissen fundoplication on impaired esophageal motility.

METHODS

In this pathological manometric study, we divided the patients into two groups preoperatively: the hypomotility group (mean amplitude of esophageal contraction wave <40 mm Hg; HYPO group, n = 11) and the normal group (mean amplitude of esophageal contraction wave >40 mm Hg; NORM group, n = 43). The amplitudes of esophageal contraction waves 3 and 8 cm above the lower esophageal sphincter and the percentage of peristaltic contraction waves of the tubular esophagus were analyzed pre- and postoperatively.

RESULTS

In total, 54 patients with GERD underwent esophageal manometry before and 6 months after Nissen fundoplication. The length and pressure of the lower esophageal sphincter were increased in both groups postoperatively (p < 0.01). Patients in the HYPO group (n = 11) showed a statistically significant increase of mean amplitude of esophageal contraction (32.8 vs. 57.3 mm Hg; p < 0.01), while no change was found in the NORM group (n = 43). A total of 72% of patients with preoperative motility disorder showed normal postoperative manometry.

CONCLUSION

Nissen fundoplication normalizes esophageal motility, especially in patients with preoperative hypomotility. Patients with impaired esophageal motility should not per se be excluded from antireflux surgery.

Is the advanced age a contraindication to GERD laparoscopic surgery? Results of a long term follow-up

Background

In this prospective non randomized observational cohort study we have evaluated the influence of age on outcome of laparoscopic total fundoplication for GERD.

Methods

Six hundred and twenty consecutive patients underwent total laparoscopic fundoplication for GERD. Five hundred and twenty-four patients were younger than 65 years (YG), and 96 patients were 65 years or older (EG). The following parameters were considered in the preoperative and postoperative evaluation: presence, duration, and severity of GERD symptoms, presence of a hiatal hernia, manometric and 24 hour pH-monitoring data, duration of operation, incidence of complications and length of hospital stay.

Results

Elderly patients more often had atypical symptoms of GERD and at manometric evaluation had a higher rate of impaired esophageal peristalsis in comparison with younger patients. The duration of the operation was similar between the two groups. The incidence of intraoperative and postoperative complications was low and the difference was not statistically significant between the two groups. An excellent outcome was observed in 93.0% of young patients and in 88.9% of elderly patients (p = NS).

Conclusions

Laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients, warranting low morbidity and mortality rates and a significant improvement of symptoms comparable to younger patients.

Impact of ineffective oesophageal motility and wrap type on dysphagia after laparoscopic fundoplication

BACKGROUND

Laparoscopic 360° fundoplication is the most common operation for gastro-oesophageal reflux disease, but is associated with postoperative dysphagia in some patients. Patients with ineffective oesophageal motility may have a higher risk of developing postoperative dysphagia, but this remains unclear.

METHODS

From 1991 to 2010, 2040 patients underwent primary laparoscopic fundoplication for gastro-oesophageal reflux disease and met the study inclusion criteria; 343 had a 90°, 498 a 180° and 1199 a 360° fundoplication. Primary peristalsis and distal contraction amplitude during oesophageal manometry were determined for 1354 patients. Postoperative dysphagia scores (range 0-45) were recorded at 3 and 12 months, then annually. Oesophageal dilatations and/or reoperations for dysphagia were recorded.

RESULTS

Preoperative oesophageal motility did not influence postoperative dysphagia scores, the need for dilatation and/or reoperation up to 6 years. Three-month dysphagia scores were lower after 90° and 180° compared with 360° fundoplication (mean(s.e.m.) 8·0(0·6) and 9·8(0·5) respectively versus 11·9(0·4); P < 0·001 and P = 0·003), but these differences diminished after 6 years of follow-up. The incidence of dilatation and reoperation for dysphagia was lower after 90° (2·6 and 0·6 per cent respectively) and 180° (4·4 and 1·0 per cent) fundoplications than with a 360° wrap (9·8 and 6·8 per cent; both P < 0·001 versus 90° and 180° groups).

CONCLUSION

Tailoring the degree of fundoplication according to preoperative oesophageal motility by standard manometric parameters has no long-term impact on postoperative dysphagia. There is, however, a proportionate increase in short-term dysphagia scores with increasing degree of wrap, and a corresponding proportionate increase in dilatations and reoperations for dysphagia. These differences in dysphagia scores diminish with time.

Evidence-based appraisal in laparoscopic Nissen and Toupet fundoplications for gastroesophageal reflux disease

AIM: To demonstrate the optimal surgical procedure for gastroesophageal reflux disease.

METHODS: The electronic databases of Medline, Elsevier, Springerlink and Embase over the last 16 years were searched. All clinical trials involved in the outcomes of laparoscopic Nissen fundoplication (LNF) and laparoscopic Toupet fundoplication (LTF) were identified. The data of assessment in benefits and adverse results of LNF and LTF were extracted and compared using meta-analysis.

RESULTS: We ultimately identified a total of 32 references reporting nine randomized controlled trials, eight prospective cohort trials and 15 retrospective trials. These studies reported a total of 6236 patients, of whom 4252 (68.18%) underwent LNF and 1984 (31.82%) underwent LTF. There were no differences between LNF and LTF in patients’ satisfaction, perioperative complications, postoperative heartburn, reflux recurrence and re-operation. Both LNF and LTF enhanced the function of lower esophageal sphincter and improved esophagitis. The postoperative dysphagia, gas-bloating syndrome, inability to belch and the need for dilatation after LNF were more common than after LTF. Subgroup analyses showed that dysphagia after LNF and LTF was similar in patients with normal esophageal peristalsis (EP), but occurred more frequently in patients with weak EP after LNF than after LTF. Furthermore, patients with normal EP after LNF still had a higher risk of developing dysphagia than did patients with abnormal EP after LTF.

CONCLUSION: Compared with LNF, LTF offers equivalent symptom relief and reduces adverse results.

Randomized controlled trial of laparoscopic Nissen versus Lind fundoplication for gastro-oesophageal reflux disease

OBJECTIVE

To compare the effect of laparoscopic Nissen and Lind fundoplication on gastro-oesophageal reflux disease by means of a prospective randomized controlled trial.

MATERIAL AND METHODS

One hundred and twenty-one patients were randomized to undergo either Nissen (61) or Lind (60) fundoplication. Initial enrollment and subsequent clinical appointments were undertaken 1, 3, 6 and 12 months after the procedure using a standardized questionnaire. Ambulatory pH monitoring and manometry were undertaken both preoperatively and at approximately 3 months post-procedure.

RESULTS

The mean operating time was similar in both groups (44.8 versus 45 min). One operation in the Lind group was converted to open surgery. Postoperative dysphagia symptoms at 3 and 6 months were higher in the Nissen fundoplication group than in the Lind group (3 months p=0.003; 6 months p=0.020). The time taken to return to work was statistically longer in the Nissen group: at 1 month, 9 of 40 versus 2 of 45 patients had not returned to full activities (p=0.013). Three individuals required re-operation in the Nissen group and 4 individuals in the Lind group because of dysphagia caused by mechanical obstruction. Both procedures demonstrated good Visick scores at 12 months; the Nissen group having 33 (97%) patients with a Visick score of 1 or 2, and the Lind group having 38 (100%) patients with a Visick score of 1 or 2.

CONCLUSIONS

Both operations provide good quantitative and qualitative control of gastro-oesophageal reflux. Operation time and postoperative comparators were similar in both groups. There were no statistically significant differences between the groups at 1 year.

Antireflux transoral incisionless fundoplication using EsophyX: 12-month results of a prospective multicenter study

Background

A novel transoral incisionless fundoplication (TIF) procedure using the EsophyX system with SerosaFuse fasteners was designed to reconstruct a full-thickness valve at the gastroesophageal junction through tailored delivery of multiple fasteners during a single-device insertion. The safety and efficacy of TIF for treating gastroesophageal reflux disease (GERD) were evaluated in a prospective multicenter trial.

Methods

Patients (n = 86) with chronic GERD treated with proton pump inhibitors (PPIs) were enrolled. Exclusion criteria included an irreducible hiatal hernia > 2 cm.

Results

The TIF procedure (n = 84) reduced all hiatal hernias (n = 49) and constructed valves measuring 4 cm (2–6 cm) and 230° (160°–300°). Serious adverse events consisted of two esophageal perforations upon device insertion and one case of postoperative intraluminal bleeding. Other adverse events were mild and transient. At 12 months, aggregate (n = 79) and stratified Hill grade I tight (n = 21) results showed 73% and 86% of patients with ≥50% improvement in GERD health-related quality of life (HRQL) scores, 85% discontinuation of daily PPI use, and 81% complete cessation of PPIs; 37% and 48% normalization of esophageal acid exposure; 60% and 89% hiatal hernia reduction; and 62% and 80% esophagitis reduction, respectively. More than 50% of patients with Hill grade I tight valves had a normalized cardia circumference. Resting pressure of the lower esophageal sphincter (LES) was improved significantly (p < 0.001), by 53%. EsophyX-TIF cured GERD in 56% of patients based on their symptom reduction and PPI discontinuation.

Conclusion

The 12-month results showed that EsophyX-TIF was safe and effective in improving quality of life and for reducing symptoms, PPI use, hiatal hernia, and esophagitis, as well as increasing the LES resting pressure and normalizing esophageal pH and cardia circumference in chronic GERD patients.

Persistent dysphagia after laparoscopic fundoplication for gastro-esophageal reflux disease

Persistent postoperative dysphagia is a potentially severe complication of fundoplication for gastroesophageal reflux disease (GERD). The aim of this retrospective study was to analyze our experience of laparoscopic fundoplication for GERD in 276 consecutive patients, to determine the frequency of postoperative dysphagia and assess treatments and outcomes. There was no relation between preoperative dysphagia, present in 24 patients (8.7%), and postoperative DeMeester grade 2 or 3 dysphagia, present in 25 patients (9.1%). Ten (3.6%) patients had clinically significant postoperative dysphagia, eight (2.9%) underwent esophageal dilation, with symptom improvement in five. Four (1.4%) of our patients (two with failed dilation) and 11 patients receiving antireflux surgery elsewhere, underwent re-operation for persistent dysphagia 12 months (median) after the first operation. DeMeester grade 0 or 1 dysphagia was obtained in 10/13 evaluable patients. Our experience is fully consistent with that of the recent literature. Redo surgery is necessary in only a small fraction of operated patients with GERD with good probability of resolving the dysphagia. Best outcomes are obtained when an anatomical cause of the dysphagia is documented preoperatively.

Influence of esophageal motility on the outcome of laparoscopic total fundoplication

The aim of this study is to evaluate if esophageal dysmotility can influence the outcome of laparoscopic total fundoplication for gatro-esophageal reflux disease (GERD). The advent of laparoscopic fundoplication has greatly reduced the morbidity of antireflux surgery and by now, it should be considered the surgical treatment of choice for GERD. Some authors assert that total versus partial fundoplication should improve the rate of postoperative dysphagia or gas bloat syndrome, particularly in patients with esophageal dysmotility. From September 1992 to December 2005, 420 consecutive patients 171 male and 249 female, mean age 42.8 years (range 12-80) underwent laparoscopic Nissen-Rossetti fundoplication. At manometric evaluation, we divided patients into two groups: group A (163/420; 38.8%) with impaired esophageal peristalsis (peristaltic waves with a pressure < 30 mmHg), and group B (257/420; 61.2%) without impaired peristalsis. We followed up clinically 406 out of 420 (96.7%) patients, 156/163 patients (95.7%) in group A and 250/257 patients (97.3%) in group B. An excellent outcome was observed in 143/156 (91.7%) group A patients and in 234/250 (93.6%) group B patients (P = NS). Both groups showed significant improvement in clinical symptom score with no statistically significant difference between patients with normal and impaired peristalsis. Thus, preoperative defective esophageal peristalsis is not a contraindication to total laparoscopic fundoplication.

Nissen versus Toupet fundoplication: results of a randomized and multicenter trial

BACKGROUND

Laparoscopic Toupet fundoplication (TF) is reported to be as effective as Nissen (NF), but to be associated with fewer unfavorable postoperative side-effects. This study evaluates the one- and three-year clinical outcome of 140 randomized patients after a laparoscopic NF or TF.

PATIENTS AND METHODS

Inclusion criteria included patients over 16 years old with complications of gastro-oesophageal reflux disease (GORD) and persistence or recurrence of symptoms after three months of treatment. Subjects with a previous history of gastric surgery or repeated fundoplication, brachy-oesophagus or severe abnormal manometry results were excluded. Seventy-seven NF and 63 TF were performed. The severity of symptoms was assessed before and after the procedure.

RESULTS

One hundred and twenty-one of the 140 patients after one year, and 118 after three years, were evaluated and no statistically significant clinical difference was observed. The level of satisfaction concerning the outcome of the operation remained high after one or three years regardless of the type of fundoplication performed.

CONCLUSIONS

Functional complications after NF are not avoided with TF.

Dysphagia after laparoscopic Nissen fundoplication

OBJECTIVE

To investigate the frequency and severity of dysphagia during the first 8 weeks after laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease. So far, there have been no studies reporting data on day-to-day occurrence of dysphagia after laparoscopic fundoplication in a consecutive series of patients. This may explain why the frequency of dysphagia varies greatly in the literature (4-100%).

MATERIAL AND METHODS

Forty consecutive patients, undergoing elective laparoscopic Nissen fundoplication, completed a standard dysphagia registration diary each day during the first 8 weeks after surgery. Patients who preoperatively had suffered from dysphagia were excluded. Thus, none of the patients had dysphagia in the 2-month period before surgery. Ten patients undergoing elective cholecystectomy served as controls. Data were quantified, and a score value of 4 or more was considered bothersome.

RESULTS

Thirty-seven patients (93%) experienced some degree of dysphagia during the observation period. Sixteen patients (44%) had at least one day with annoying dysphagia. The dysphagia started 1-2 days after surgery, was most prominent during the first few weeks, and subsided in nearly all cases after 5-6 weeks. Two patients with persistent dysphagia were treated once with balloon dilatation. None of the patients in the control group had dysphagia.

CONCLUSIONS

Nearly all patients experience some degree of dysphagia after laparoscopic Nissen fundoplication, and in nearly half of the patients it is considered annoying. However, even severe dysphagia usually disappears within 5-6 weeks. These results suggest a conservative attitude for the first 1-2 months after surgery. The data may also serve as a background for preoperative information to the patients.

Assessment of quality of life after laparoscopic Nissen fundoplication in patients with gastroesophageal reflux disease

BACKGROUND

In this study two different quality of life items are compared, and correlation of patient satisfaction with preoperative and postoperative symptoms after laparoscopic Nissen fundoplication (LNF) for chronic gastroesophageal reflux disease is evaluated.

MATERIALS AND METHODS

Between December 2002 and December 2004, 60 patients with a diagnosis of chronic gastroesophageal reflux disease scheduled for laparoscopic Nissen fundoplication were recruited prospectively and volunteered to participate in this study. Patients underwent endoscopy, and their disease-specific symptoms were scored on a scale. Quality of life was measured preoperatively and in the first and sixth postoperative months with two questionnaires: Short Form-36 (SF 36) (preoperatively) and the Gastroesophageal Reflux Disease - Health-Related Quality of Life (GERD-HRQL) (postoperatively).

RESULTS

In more than 90% of the patients, typical symptoms (regurgitation and pyrozis) were controlled postoperatively (p < 0.001). In the first postoperative month, however, dysphagia (early dysphagia) was seen in 46 (76%) patients, whereas in the sixth postoperative month (late dysphagia) its incidence decreased to only 2 (3.3%) patients. Similarly, in the first postoperative month 42 (70%) patients had gas bloating, but the incidence of this symptom decreased to 26 (43.3%) patients by the sixth month (p = 0.01). The quality-of-life measurements obtained from both SF 36 and GERD-HRQL showed that quality of life of the patients improved significantly in the related domain of each item after surgery (p < 0.001).

CONCLUSIONS

Laparoscopic Nissen fundoplication is an effective operation that controls the typical symptoms and improves the quality of life of patients, but new-onset symptoms affect postoperative well-being. For closer evaluation of the benefits of the operation, we need new questionnaires that comprehensively evaluate the symptom spectrum of GERD both preoperatively and postoperatively.

Influence of age on outcome of total laparoscopic fundoplication for gastroesophageal reflux disease

AIM: To demonstrate that age does not influence the choice of treatment for gastroesophageal reflux disease (GERD). We hypothesized that the outcome of total fundoplication in patients > 65 years is similar to that of patients aged ≤ 65 years.

METHODS: Four hundred and twenty consecutive patients underwent total laparoscopic fundoplication for GERD. Three hundred and fifty-five patients were younger than 65 years (group Y), and 65 patients were 65 years or older (group E). The following elements were considered: presence, duration, and severity of GERD symptoms; presence of a hiatal hernia; manometric evalu-ation, 24 h pH-monitoring data, duration of operation; incidence of complications; and length of hospital stay.

RESULTS: Elderly patients more often had atypical symptoms of GERD and at manometric evaluation had a higher rate of impaired esophageal peristalsis in compari-son with younger patients. A mild intensity of heartburn often leads physicians to underestimate the severity of erosive esophagitis. The duration of the operation was similar between the two groups. The incidence of intraoperative and postoperative complications was low and the difference was not statistically significant between the two groups. An excellent outcome was observed in 92.9% young patients and 91.9% elderly patients.

CONCLUSION: Laparoscopic antireflux surgery is a safe and effective treatment for GERD even in elderly patients, warranting low morbidity and mortality rates and a significant improvement of symptoms comparable to younger patients.

Effects of laparoscopic Nissen fundoplication on esophageal motility

BACKGROUND

This study aimed to evaluate the long-term impact of laparoscopic Nissen fundoplication on esophageal motility in patients with preoperative esophageal dysmotility.

METHODS

This study prospectively followed 580 patients who underwent laparoscopic Nissen fundoplication between 1992 and 1999. Esophageal manometry, 24-h pH monitoring, and symptom score assessment were performed before surgery, then 6 months, 2 years, and 5 years after surgery. Preoperatively, 533 of the patients (93.5%) had normal esophageal contractile pressure (group 1), whereas 38 of the patients (6.5%) had reduced contractile pressure (<30 mmHg) (group 2).

RESULTS

Esophageal contractile pressures increased significantly in the patients with low preoperative values, whereas it remained unchanged in the patients with normal preoperative contractile pressures. Both groups reported a significant reduction in the dysphagia symptom score after surgery.

CONCLUSION

Nissen fundoplication produces a significant long-lasting increase in esophageal contractile pressures in patients with preoperative esophageal dysmotility (i.e., contractile pressure lower than 30 mmHg). Preoperative esophageal dysmotility is therefore not a contraindication to laparoscopic Nissen fundoplication.

Symptomatic and functional outcome after laparoscopic reoperation for failed antireflux surgery

BACKGROUND

The aim was to determine symptomatic and functional outcome after reoperative antireflux surgery for recurrent reflux, persistent dysphagia and severe gas bloat, using a primarily laparoscopic surgical approach.

METHODS

This was a retrospective analysis of prospectively collected data from 118 patients, of whom 70 had reoperative surgery for recurrent reflux, 35 for dysphagia and 13 for gas bloat. DeMeester scores before and 1 year after surgery, functional symptoms after surgery and overall patient satisfaction were analysed.

RESULTS

Reoperation was completed laparoscopically in 101 patients (85.6 per cent), in 28 after previous open hiatal surgery. The operation was converted from an initial laparoscopic approach to open surgery in 17 patients. One-year follow-up data were available for 104 patients (88.1 per cent). After reoperation for recurrent reflux, 84 per cent had a DeMeester heartburn score of zero or one, and 87 per cent had a regurgitation score of zero or one. After reoperation for dysphagia, 21 of 32 patients had a dysphagia score of zero or one, with improvement observed in 25. All patients undergoing reoperation for severe gas bloat were satisfied with the outcome 1 year after operation.

CONCLUSION

Revisional surgery for recurrent reflux using a laparoscopic approach offered high rates of success and patient satisfaction. Swallowing returned to normal in two-thirds of patients after reoperation.

Antireflux Surgery in the Setting of Lung Transplantation: Strategies for Treating Gastroesophageal Reflux Disease in a High-Risk Population

In lung transplant recipients, GERD is associated with increased incidence of acute rejection, earlier onset of chronic rejection, and higher mortality. Surgical treatment of GERD in lung recipients seems to prevent early allograft dysfunction and improve overall survival. A total (360 degrees) fundoplication is shown to be a safe and effective method for treating GERD in lung transplant recipients and is the authors' procedure of choice, in most cases, for this high-risk patient population. The principal goal should be to minimize reflux of enteric contents that may lead to micro- or macroaspiration events in this complicated group of patients. Perioperative care should involve a multidisciplinary approach, including physicians and other health care providers familiar with the complexities of lung transplant recipients.

Short-term cost effectiveness and long-term cost analysis comparing laparoscopic Nissen fundoplication with proton-pump inhibitor maintenance for gastro-oesophageal reflux disease

BACKGROUND

This study examined the short-term cost-effectiveness and long-term cost of laparoscopic Nissen fundoplication (LNF) versus maintenance proton-pump inhibitor (PPI) medication for severe gastro-oesophageal reflux disease (GORD) based on a randomized clinical trial.

METHODS

Costs and outcomes for 12 months were obtained from the first 100 patients in the trial. Detailed costing was performed using resource use data from hospital records and general practitioners' notes. Short-term incremental cost-effectiveness ratios, calculated as the cost difference divided by the effectiveness difference between LNF and PPI therapy, were analysed using net benefit and bootstrap approaches. Long-term cost was examined using sensitivity analyses incorporating published data from other large series.

RESULTS

The incremental cost of LNF compared with PPI therapy per additional patient returned to a physiologically normal acid score (less than 13.9) at 3 months was pound5515 (95 per cent confidence interval (c.i.) pound3655 to pound13 400) and the incremental cost per point improvement in combined Gastro-Intestinal and Psychological Well-being score at 12 months was pound293 (90 per cent c.i. pound149 to pound5250). On average, LNF cost pound2247 (95 per cent c.i. pound2020 to pound2473) more than PPI therapy in year 1 and broke even in year 8. Break-even was highly sensitive to hospital unit costs but less sensitive to PPI ingestion rate after LNF, LNF reoperation rate, PPI relapse rate, future PPI price, PPI dose escalation and discount rate.

CONCLUSION

From a National Health Service perspective, LNF may be cost-saving after 8 years compared with maintenance PPI therapy for the treatment of GORD.

Randomized clinical trial of laparoscopic Nissen fundoplication compared with proton-pump inhibitors for treatment of chronic gastro-oesophageal reflux

BACKGROUND

Both laparoscopic Nissen fundoplication (LNF) and proton-pump inhibitor (PPI) therapy are established in the treatment of gastro-oesophageal reflux disease (GORD). The aim of this study was to compare these two treatments in a randomized clinical trial.

METHODS

Between July 1997 and August 2001, 340 patients with a history of GORD for at least 6 months were investigated by endoscopy, 24-h pH monitoring and manometry. Of these, 217 were randomized, 109 to LNF and 108 to PPI therapy. The two groups were well matched for age, sex, weight and severity of reflux. Twenty-four-hour pH monitoring and manometry were performed 3 months after treatment, and quality of life was assessed in both groups using the Psychological General Well-being Index and the Gastrointestinal Symptom Rating Scale at 3 and 12 months after treatment.

RESULTS

At 3 months there was an improvement in lower oesophageal sphincter pressure from 6.3 to 17.2 mmHg in the LNF group but no change in the PPI group (8.1 and 7.9 mmHg before and after treatment respectively) (P < 0.001). The mean DeMeester acid exposure score improved from 42.7 to 8.6 (P < 0.001) in the LNF group and from 36.9 to 17.7 in the PPI group (P < 0.001). The mean gastrointestinal symptom and general well-being scores improved from 31.7 and 95.4 respectively before treatment to 37.0 and 106.2 at 12 months after LNF, compared with changes from 34.3 and 98.5 to 35.0 and 100.4 respectively in the PPI group. The differences in both of these scores were significant between the two groups at 12 months (P = 0.003).

CONCLUSION

LNF leads to significantly less acid exposure of the lower oesophagus at 3 months and significantly greater improvements in both gastrointestinal and general well-being after 12 months compared with PPI treatment.

Functional Problems Following Esophageal Surgery

Functional problems following esophageal surgery for GERD are not infrequent. The majority of patients improve with time. Careful patient selection and attention to surgical technique are key factors in preventing such functional disorders. When anatomic abnormalities related to the fundoplication are identified, reoperation may offer symptom relief. Before embarking on re-fundoplication, a thorough preoperative evaluation of the esophageal physiology is recommended.

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.

Reflux, dysphagia, and gas bloat after laparoscopic fundoplication in patients with incidentally discovered hiatal hernia and in a control group

BACKGROUND

Laparoscopic fundoplication effectively controls reflux symptoms in patients with gastroesophageal reflux disease (GERD). However, symptom relapse and side effects, including dysphagia and gas bloat, may develop after surgery. The aim of the study was to assess these symptoms in patients who underwent laparoscopic fundoplication, as well as in control subjects and patients with hiatal hernia.

METHODS

A standardized, validated questionnaire on reflux, dysphagia, and gas bloat was filled out by 115 patients with a follow-up of 1 to 7 years after laparoscopic fundoplication, as well as by 105 subjects with an incidentally discovered hiatal hernia and 238 control subjects.

RESULTS

Patients who underwent fundoplication had better reflux scores than patients with hiatal hernia ( P = .0001) and similar scores to control subjects ( P = .11). They also had significantly more dysphagia and gas bloat than patients with hiatal hernia and controls ( P < .005 for all comparisons). Gas bloat and dysphagia were more severe in hiatal hernia patients than in controls ( P < 0.005). After fundoplication, the 25% of the patients with the shortest follow-up (1.5 +/- 0.2 years) and the 25% patients with the longest follow-up (5.8 +/- 0.6 years) had similar reflux, dysphagia, and gas bloat scores ( P = .43, .82, and .85, respectively).

CONCLUSION

In patients with severe GERD, laparoscopic fundoplication decreases reflux symptoms to levels found in control subjects. These results appear to be stable over time. However, patients who underwent fundoplication experience more dysphagia and gas bloat than controls and patients with hiatal hernia-symptoms that should be seen as a side effect of the procedure and of GERD itself.

Gastroenterologists' views of symptoms following laparoscopic fundoplication: anecdotally based medicine?

BACKGROUND

Currently gastro-oesophageal reflux disease (GORD) can be managed either medically or surgically. The management decision is often based on the referring doctor's perception of the pros and cons of surgical management versus the medical alternative. A large group of gastroenterologists was surveyed to determine their understanding of the common outcomes of surgical management of GORD.

METHODS

A 15-question survey was sent to all gastroenterologists in Australia who were members of the Gastroenterology Society of Australia. Questions centred on management decisions and postoperative symptoms in fundoplication patients. The findings were compared to current published outcome data.

RESULTS

One hundred and thirty-four gastroenterologists responded anonymously to the survey. More than 75% described fundoplication as a safe and established procedure, and 80% had referred patients who were well controlled on medication for surgical management. The gastroenterologists' perceptions of the problems of postoperative dysphagia and bloating differed from published outcomes.

CONCLUSIONS

Gastroenterologists are often the gatekeepers for the management of patients with GORD. The understanding that this group has about surgical outcomes is important so that patients can make well-informed management decisions. The present study found that gastroenterologists are likely to convey to their patients higher degrees of postoperative dysphagia and bloating following fundoplication than is actually reported. This may deter some patients who would benefit from fundoplication from consulting a surgeon.

Total fundoplication is superior to partial fundoplication even when esophageal peristalsis is weak1 1No competing interests declared

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.

Surgery of gastroesophageal reflux disease: a competitive or complementary procedure?

The management of chronic gastroesophageal reflux disease (GERD) has both been simplified and immensely improved by the development of modern medical therapies. These are built entirely on the concept of profound acid inhibition, which is very successful in a substantial proportion of GERD patients. Despite the efficacy of proton pump inhibitors (PPIs) some failures are unavoidable, and some patients experience incomplete control of major GERD symptoms on ordinary dosing of PPIs. Although the safety profile of PPIs is very reassuring, some people express some concern about the safety of drug treatment extending beyond 10 years especially when alternative therapeutic strategies are available. Some patients complain of alleged respiratory complications to severe reflux, and in those situations as well as in cases with e.g. Barrett's esophagus, a complete control of reflux also incorporating the duodenal components in the refluxate may be warranted. In all those situations antireflux surgery can be considered indicated for the treatment of chronic GERD and thus be looked upon as complementary to medical therapy. Furthermore, some patients who have their GERD symptoms under control on PPIs still want to have an operation to avoid dependency on drugs. Hence in none of these clinical situations does antireflux surgery play a competitive role in relation to medical therapy. However, in the very few randomized clinical trials in which a head-to-head comparison has been completed between medical and surgical therapy, the latter has been found to be somewhat more effective in terms of reflux control. The other side of the coin is that antireflux surgery has some side effects that signify the importance of this surgery being performed in specialized centers.

Symptomatic outcome of laparoscopic fundoplication, using a minimal dissection technique

BACKGROUND AND AIMS

The symptomatic outcome of 135 consecutive patients operated laparoscopically for gastro-oesophageal reflux disease (GORD) by a minimal paraoesophageal dissection technique is reported.

PATIENTS AND METHODS

At a median (range) follow-up time of 25 months (6-82 months) we sent the patients a self-assessment questionnaire regarding symptomatic outcome of the operation.

RESULTS

Median (range) operation time was 65 minutes (33-185 minutes). Per- and postoperative complications occurred in four patients (3%). There were no conversions and no mortality. The answering rate was 91%. Of all patients, 87% were free of reflux symptoms, 84% without any medication, 99% reported at least improvement, 90%-95% reported persistence of favourable outcome, 90% were satisfied, 91% scored the outcome as good or excellent, and 95% of the patients were ready to recommend the operation to family or friend. However, 31% reported dysphagia and 76% troublesome gas bloating, causing problems in 24% of the patients. No association between different outcome variables and crural repair could be shown.

CONCLUSION

Laparoscopic fundoplication can be done in a simple and fast way, with minimal morbidity, short hospital stay and without compromising outcome. Nevertheless, the operation is seldom without some sequel for the patient.

Laparoscopic surgery for gastroesophageal reflux disease patients with impaired esophageal peristalsis: total or partial fundoplication?

BACKGROUND

It has been proposed that partial fundoplication is associated with less incidence of postoperative dysphagia and consequently is more suitable for patients with gastroesophageal reflux disease (GERD) and impaired esophageal body motility. The aim of this study was to assess whether outcomes of Toupet fundoplication (TF) are better than those of Nissen-Rossetti fundoplication (NF) in patients with GERD and low-amplitude esophageal peristalsis.

STUDY DESIGN

Thirty-three consecutive patients with proved GERD and amplitude of peristalsis at 5 cm proximal to lower esophageal sphincter (LES) less than 30 mmHg were randomly allocated to undergo either TF (19 patients: 11 men, 8 women; mean age: 61.7 +/- 8.7 SD years) or NF (14 patients: 7 men, 7 women; mean age: 59.2 +/- 11.5 years), both by the laparoscopic approach. Pre- and postoperative assessment included clinical questionnaires, esophageal radiology, esophageal transit time study, endoscopy, stationary manometry, and 24-hour ambulatory esophageal pH testing.

RESULTS

Duration of operation was significantly prolonged in the TF arm (TF: 90 +/- 12 minutes versus NF: 67 +/- 15 minutes; p < 0.001). At 3 months postoperatively, the incidences of dysphagia (grades I, II, III) and gas-bloat syndrome were higher after NF than after TF (NF: 57% versus TF: 16%; p < 0.01 and NF: 50% versus TF: 21%; p = 0.02, respectively), but decreased to the same level in both groups at the 1-year followup (NF: 14% versus TF: 16% and NF: 21% versus TF: 16%, respectively). At 3 months postoperatively, patients with NF presented with significantly increased LES pressure than those with TF (p = 0.02), although LES pressure significantly increased after surgery in both groups, as compared with preoperative values. Amplitude of esophageal peristalsis at 5 cm proximal to LES increased postoperatively to the same extent in both groups (TF, preoperatively: 21 +/- 6 mmHg versus postoperatively: 39 +/- 12 mmHg; p < 0.001, and NF, preoperatively: 20 +/- 8 mmHg versus postoperatively: 38 +/- 12 mmHg; p < 0.001). Reflux was abolished in all patients of both groups.

CONCLUSIONS

Both TF and NF efficiently control reflux in patients with GERD and low amplitude of esophageal peristalsis. Early in the postoperative period, TF is associated with fewer functional symptoms, although at 1 year after surgery those symptoms are reported at similar frequencies after either procedure.

Influence of spastic motor disorders of the esophageal body on outcomes from laparoscopic antireflux surgery

BACKGROUND

The clinical outcomes of laparoscopic antireflux surgery (LARS) in patients with the spectrum of nonspecific spastic esophageal motor disorders (NSSDs) are not known.

METHODS

From a prospective database of patients undergoing LARS between 1997 and 2000, those with preoperative manometry at our institution and follow-up at ?6 months were identified.

RESULTS

Of the 121 patients, 35 had NSSDs. There were no differences in symptoms between groups preoperatively, but in the immediate postoperative period NSSD patients had more symptoms than nonspastic patients. At 18-month mean follow-up, NSSD patients reported significantly more heartburn (22% vs 7%), waterbrash (14% vs 4%), and medication usage (17% vs 5%) than nonspastic patients (p <0.05 for each). Despite this difference, nearly all patients reported subjective improvement postoperatively, and the degree of improvement was similar between groups.

CONCLUSIONS

Patients with NSSDs are more likely to have esophageal symptoms following LARS than subjects without these abnormalities. However, these patients still experience significant improvement in preoperative symptoms.

Ineffective motility is not a marker for gastroesophageal reflux disease

OBJECTIVE

Previous studies have suggested that ineffective esophageal motility (IEM) may be a marker for gastroesophageal reflux disease (GERD), particularly supraesophageal reflux disease. We evaluated the relationship between esophageal acid exposure and esophageal body motility in patients undergoing both esophageal manometry and 24-h pH metry in the absence of antisecretory therapy.

METHODS

We conducted a retrospective database review of 84 patients (mean age 47 yr, 46% male) evaluated in our GI physiology laboratory. The indication for testing was recorded and characterized as esophageal or supraesophageal. Abnormal esophageal acid exposure was defined as a distal esophageal pH <4 for more than 4.2% of the total monitoring time (>6.3% upright, >1.2% supine) or a proximal esophageal acid exposure time of greater than 1.1% total (>1.3% upright, 0% supine). IEM was defined as more than two of 10 ineffective peristaltic waves.

RESULTS

Seventy-two patients had esophageal-presenting symptoms, and 12 had supraesophageal symptoms. The prevalence of abnormal esophageal acid exposure was similar in patients with esophageal and supraesophageal symptoms (69% vs 92%, p = 0.17). Abnormal motility was identified in 26 patients (31%). IEM was the most common motility disturbance (77%, 20 patients). The frequency of motility disorders was similar in patients with and without abnormal esophageal acid exposure (30% vs 35%, p = 0.79), in patients with esophageal or supraesophageal symptoms (32% vs 25%, p = 0.75, for all patients; 30% vs 27%, p = 1.00, for patients with abnormal esophageal acid exposure), and among upright, supine, and combined refluxers (33%, 9%, and 35%, p = 0.26).

CONCLUSIONS

IEM does not stand alone as a significant marker for the presence of GERD in general or supraesophageal reflux disease in particular.

Early reoperation for acute dysphagia following laparoscopic fundoplication

BACKGROUND

A small number of patients develop acute severe dysphagia for which reoperation is necessary within 10 days of laparoscopic fundoplication. The aim of this study was to identify clinical variables that might predict the likelihood of this condition occurring, such that it could be avoided in the future.

METHODS

This was a prospective cohort study from three tertiary referral centres, using reoperation for acute dysphagia as the main outcome variable. Gastrointestinal symptom rating scale, and psychological well-being index questionnaires were undertaken before laparoscopic fundoplication, and dysphagia scores were determined before operation and 1 year later. Standard preoperative assessment included gastroscopy, oesophageal manometry and pH studies.

RESULTS

Twelve (1.9 per cent) of the 617 patients suffered acute dysphagia, which was predicted by older age and female sex, and resulted in a longer duration of hospital stay. This condition was not predicted by any other demographic, clinical, investigative or operative variables.

CONCLUSION

The study did not identify useful criteria by which severe acute dysphagia could be anticipated and thereby avoided following laparoscopic fundoplication.

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.

[Surgical treatment of gastroesophageal reflux disease in adults]

Pathological gastroesophageal reflux is common. The aim of this review was to compare the results of different surgical techniques. Papers were selected on Medline from 1990 to April 2001. A critical analysis was performed, concerning definitions of included patients, surgical techniques, and criteria of evaluation. For comparison, the results of 23 randomized studies were mainly selected. Their heterogeneity has not allowed a meta-analysis. A few techniques had poorer results than others: simple closure of His angle, Hill operation, Belsey Mark IV technique, and Angelchik prosthesis. In most studies, results of partial fundoplication on reflux were as good as those of total Nissen fundoplication and fewer patients had postoperative dysphagia. In a double blind trial, immediate advantages of laparoscopic approach were less important than those observed in non comparative studies. Another trial was interrupted after inclusion of 103 patients because of the higher rate of side-effects in the laparoscopic group. These results may help the surgeon in the choice of a technique. Patients have to be informed of potential adverse effects of the different techniques chosen by their surgeon.

[Clinical and functional results after Laparoscopic fundoplication. Prospective evaluation]

OBJECTIVE

To prospectively assess the medium- and long-term clinical and functional results in consecutive patients undergoing laparoscopic procedures for gastroesophageal reflux.

PATIENTS AND METHOD

The series included the interventions performed or assisted by the first author in 325 patients referred for surgical evaluation between December 1992 and June 2000. Forty patients were excluded from the study because they did not fulfil the inclusion criteria for laparoscopic surgery. A further 20 patients who underwent laparoscopic surgery were excluded because they required conversion to open surgery. Thus, 265 patients were included in the study. One hundred ninety-six total fundoplications (Nissen-Rossetti) and 69 partial fundoplications(42 posterior-Toupet and 27 anterior-Dor) were performed. The surgical technique employed was a slight modification of that described by Dallemagne et al with five-trocars. Preoperative evaluation was established by clinical features, endoscopy with biopsy, barium contrast radiography, esophageal manometry and esophageal pH monitoring.

RESULTS

The mean follow-up was 47.1 3.3 months (range: 4-92 months). Heartburn, regurgitation, and dysphagia were relieved in 92.5%, 97.7%, and 88.1% of patients respectively. Complete relief of symptoms was achieved in all patients who presented preoperative respiratory symptoms as a complication of gastroesophageal reflux. Esophagitis healed in 98.2% of patients with preoperative esophagitis. Correction of lower esophageal sphincter pressure and lower esophageal sphincter length were statistically significant compared with preoperative status (p = 0.006 and p = 0.003, respectively). Pre- and postoperative differences in the percentage of patients with a pH < 4 in 24-hour ambulatory esophageal pH monitoring were also significant (p = 0.005), confirming correction of acid reflux. Morbidity appeared in 6.7% of patients and there was no mortality. Conversion to open procedures was required in 7.5%. The mean operative time was 115 6.3 minutes.

CONCLUSIONS

These preliminary results suggest that when performed by experienced surgeons laparoscopic fundoplication provides an excellent alternative in selected patients with gastroesophageal reflux. Both medium- and long-term clinical and functional results, as well as morbidity, were satisfactory and were similar to those of open fundoplication.
