Fundoplication in paediatric surgery: a survey in 40 German institutions

BACKGROUND

There is no generally accepted standard surgical approach to gastrooesophageal reflux disease (GERD) at present. However, laparoscopic fundoplication has been advocated to be the procedure of choice for gastrooesophageal reflux disease in children. We aimed to assess the standards of the diagnostic workup and operative techniques in paediatric surgical institutions in Germany.

MATERIAL AND METHODS

A questionnaire including 14 items was sent to all 71 departments of paediatric surgery in Germany. Forty (56 %) took part in the survey. Concepts of routine diagnostic workup, operative techniques, number of procedures, and conversions were assessed.

RESULTS

The average annual frequency of fundoplications was less than 20 in 36 units (90 %). Experience with laparoscopic fundoplication was present in 24 institutions (60 %). In 19 out of these (79 %) fewer than 50 laparoscopic fundoplications had been performed altogether up to the time of the survey. Out of 584 fundoplications performed in the year 2002, 184 (32 %) had been done laparoscopically. The ratio of conventional versus laparoscopic fundoplication was 170/130 (57/43 %) in academic, and 226/54 (81/19 %) in non-academic departments. The preferred technique of fundoplication, irrespective of the approach, was the Nissen wrap in 28 (70 %) of the departments. The number of paediatric surgeons performing laparoscopic fundoplication was 1 - 2 in 16 institutions (67 %), 3 or 4 in 6 (25 %), and 5 in 2 (8 %) departments. The conversion rate was reported to be less than 5 % in 15 departments (63 %), and 5 - 10 % in 3 (13 %).

CONCLUSION

The laparoscopic approach for surgical repair of GERD in children is not yet generally accepted in Germany. In most departments, training remains problematic due to low numbers of procedures. However, the feasibility of laparoscopic fundoplication in Germany is excellent, with a low rate of conversions.

[Results of laparoscopic antireflux surgery at five years and beyond]

Laparoscopic antireflux surgery was first introduced in 1991. As with any new technique, there was a learning curve during which surgeons had a unique opportunity to prospectively document the evolution of the technique and its results. We have regularly assessed our results and conducted randomised prospective studies with the aim of obtaining solid long-term outcome data. We now have at least 5 years of follow-up for two groups of patients. Group I consists of the first 178 patients who underwent fundoplicature, i.e. during the learning curve. Group II consists of 107 patients who were enrolled in a randomised trial comparing total fundoplicature with anterior partial fundoplication. The re-operation rate was 15% in Group I and only 6% in Group II. Overall, about 85% of patients were free of reflux symptoms 5-8 years after fundoplication, indicating that laparoscopic surgery provides a durable benefit in the vast majority of patients.

Witnessed and unwitnessed esophageal foreign bodies in children

OBJECTIVE

The purpose of this study was to describe the clinical presentation of children with either an unwitnessed or witnessed esophageal foreign body.

METHODS

Retrospective chart review was performed. Patients were identified using ICD-9 code for esophageal foreign body. Clinical data and management techniques, along with complications were abstracted.

RESULTS

For the 5-year period of review, 255 patients were identified with an esophageal foreign body. 214 children had a witnessed ingestion. The mean age of the unwitnessed ingestion group was 2.3 years, compared to 4.6 years for a witnessed ingestion. In both groups, males and females were distributed equally and the most common ingested object was a coin. Bivariate, unadjusted analysis revealed that history of wheeze (OR, 4.35) and fever (OR, 11.15) had the largest association with patients who had an unwitnessed ingestion. Multivariate analysis indicated that any physical findings of wheeze, rhonchi, stridor, or retractions were associated significantly with a diagnosis of an unwitnessed foreign body. Children less than 2 years of age and with a documented fever are also predictive of an unwitnessed ingestion. Eleven children (4.3%) with esophageal abnormalities were also noted to have foreign bodies.

CONCLUSIONS

Children who present to the emergency department two years old and younger, who have a documented fever and with respiratory findings should be considered at risk for having a retained esophageal foreign body. Children with esophageal abnormalities may also be at risk for retained esophageal foreign bodies.

Austrian experiences with redo antireflux surgery

BACKGROUND

From 1996, the entire number of fundoplications performed in Austria increased dramatically, favoring the laparoscopic technique. Despite good results, some patients experience failure of antireflux surgery and therefore require redo surgery if medical therapy fails to control symptoms. The aim of the study was to describe the refundoplication policy in Austria with evaluation of the postoperative results.

METHODS

A questionnaire was sent to all Austrian surgical departments at the beginning of 2003 with questions about redo fundoplications (number, techniques, intraoperative complications, history, migration of patients, preoperative workup, mortality, and postoperative long-term complaints). It also included questions about primary fundoplications (number, technique, postoperative symptoms).

RESULTS

Out of 4,504 primary fundoplications performed in Austria since 1990, 3,952 have been carried out laparoscopically. In a median of 31 months after the primary operation, 225 refundoplications have been performed, laparoscopically in the majority of patients. The Nissen and the partial posterior fundoplication were the preferred techniques. The conversion rate in these was 10.8%, mainly because of adhesions and lacerations of the spleen, the stomach, and the esophagus. The mortality rate after primary fundoplications was 0.04%, whereas the rate after refundoplications was 0.4%, all resulting from an open approach.

CONCLUSION

Laparoscopic refundoplications are widely accepted as a treatment option after failed primary antireflux surgery in Austria. However, the conversion rate is 6 times higher and the mortality rate is 10 times higher than for primary antireflux surgery. Therefore, redo fundoplications should be performed only in departments with large experience.

High prevalence of gastroesophageal reflux in children after lung transplantation

Bronchiolitis obliterans and its clinical correlate bronchiolitis obliterans syndrome (BOS) are a major cause of morbidity and mortality following lung transplantation. Gastroesophageal reflux disease (GERD) may be a contributing factor for the development of BOS. Since 2002, all recipients of lung and heart-lung transplantation at our institution have been routinely investigated for GERD. In this observational study, we report on the prevalence of GERD in this population, including all pediatric patients undergoing single (SLTx) or double (DLTx) lung transplantation or heart-lung (HLTx) transplantation from January 2003-May 2004. GERD was assessed 3-6 months after transplantation by 24-hr pH testing. The fraction time (Ft) with a pH < 4 within a 24-hr period was recorded. Spirometry data, episodes of confirmed acute rejection, and demographic data were also collected. Ten transplant operations were performed: 4 DLTx, 1 SLTx, and 5 HLTx. Nine patients had cystic fibrosis. One patient had end-stage pulmonary disease secondary to chronic aspiration pneumonia and postadenovirus lung damage. Of 10 patients tested, 2 had severe GERD (Ft > 20%), 5 had moderate GERD (Ft 10-20%), 2 had mild GERD (Ft 5-10%), and 1 had no GERD. The only patient in this group with no GERD had a Nissen fundoplication pretransplant. All study patients were asymptomatic for GERD. All patients with episodes of rejection had moderate to severe GERD posttransplant. There was no association between severity of GERD and peak spirometry results posttransplant. Moderate to severe GERD is common following lung transplantation in children.

Laparoscopic Nissen fundoplication in patients with nonerosive reflux disease. Long-term quality-of-life assessment and surgical outcome

BACKGROUND

It is known that laparoscopic antireflux surgery (LARS) can achieve an excellent surgical outcome including quality of life improvement in patients with erosive gastroesophageal reflux disease (GERD; EGD-positive). Less is known about the long-term surgical outcome in GERD patients who have no evidence of esophagitis (EGD-negative) before surgery. The aim of this study was to evaluate the surgical outcome in a well-selected group of EGD-negative patients compared to that of EGD-positive patients.

METHODS

From a large sample of more than 500 patients who underwent LARS, 89 EGD-negative patients (mean age, 51 +/- 6 years; 56 males) were treated surgically because of persistent reflux-related symptoms despite medical therapy. In all cases, preoperative 24-h pH monitoring showed pathological values. To perform a comparative analysis, a matched sample of EGD-positive patients (mean age, 54 +/- 10 years; 58 males) was selected from the database. Surgical outcome included for all patients objective data (e.g., manometry and pH data and endoscopy), quality of life evaluation [Gastrointestinal Quality of Life Index (GIQLI)] symptom evaluation, as well as patients' satisfaction with surgery. The data of a complete 5-year follow-up are available.

RESULTS

There were no significant differences in symptomatic improvement, percentage of persistent surgical side-effects, or objective parameters. In general, patients' satisfaction with surgery was comparable in both groups: 95% rated long-term outcome as excellent or good and would undergo surgical treatment again if necessary, respectively. Quality of life improvement was significantly better (p < 0.05) in the EGD-negative group because of the fact that GIQLI was more impaired before surgery (preoperative GIQLI, 81.7 +/- 11.6 points/EGD-negative vs 93.8 +/- 10.3 points/EGD-positive). Five years after surgery, GIQLI in both groups (121.2 +/- 8.5 for EGD-negative vs 120.9 +/- 7.3 for EGD-positive) showed comparable values to healthy controls (122.6 +/- 8.5).

CONCLUSION

We suggest that LARS is an excellent treatment option for well-selected patients with persistent GERD-related symptoms who have no endoscopic evidence of esophagitis.

Laparoscopic myotomy for oesophageal achalasia--adding an antireflux procedure is not always necessary

Laparoscopy is the access of choice for functional surgery of the gastroesophageal junction, and oesophagocardiomyotomy, as the conventional surgical treatment of achalasia, is one of the favourable indications for laparoscopic surgery. Laparoscopic anterior myotomy technique is highly effective and secure for relieving dysphagia with minimal risk of gastroesophageal reflux. Fifteen patients with the diagnosis of achalasia were treated with laparoscopic anterior face oesophagocardiomyotomy without a concomitant antireflux procedure. There was not any perioperative complication and no procedure was converted to open operation. Oesophageal cineradiography, manometry and 24-h pH monitoring were repeated postoperatively. Manometry showed a significant reduction of the resting tone (48-34.4 to 18-3.2 mmHg), and patients were free of symptoms for reflux and dysphagia at the follow-up between 8 and 96 (median 42) months. Only one patient needed pneumatic dilation, 1 year after the operation for mild dysphagia, and one patient had moderate reflux, which was managed by medication. Thanks to minimal invasive technique of laparoscopic surgery and intraoperative endoscopy, oesophagocardiomyotomy can safely be performed in a length needed without dividing lateral and posterior phrenoesophageal ligamentous attachments. Consequently, adding an antireflux procedure routinely is not necessary. We advocate laparoscopic anterior oesophagocardiomyotomy alone as the first-line treatment for achalasia.

Mid term analysis of safety and quality of life after the laparoscopic repair of paraesophageal hiatal hernia

BACKGROUND

Initial experience with the laparoscopic repair of paraesophageal and type III mixed hiatal hernias showed that it is safe and feasible, with excellent immediate and short-term results. However, after a longer follow-up, a recurrence rate of < or =40% has been demonstrated. Data related to the outcome of paraesophageal hernia repair and the recurrence rate are still lacking. Quality-of-life scores may offer a better means of assessing the impact of surgical treatment on the overall health status of patients. Therefore, we performed prospective evaluation of anatomic and/or symptomatic recurrences after paraesophageal or large hiatal hernia repair. In addition, we investigated the correlation between recurrence and the patient's quality of life.

METHODS

All patients after who had undergone repair of paraesophageal of mixed hiatal hernia were identified prospectively from a database consisting of all patients who had had laparoscopic operations for gastroesophageal pathology at our hospital between February 1998 and December 2002. The preoperative symptoms were taken from patients' clinical files. In March 2003, all patients with > or =6 months of follow-up had a barium swallow and were examined for radiological and clinical signs of recurrence. Thereafter, the patients' quality of life after surgery was evaluated using three standard questionnaires (Short Form 36 [SF-36], Glasgow Dyspepsia Severity Score [GDSS], and Gastrointestinal Quality of Life Index [GIQLI].

RESULT

During the study period, 46 patients had been operated on. The mean age was 63 years (range, 28-93). Thirty seven of them had a follow-up of > or =6 months. Eight patients (21%) had postoperative gastrointestinal symptoms. Barium swallow was performed in 30 patients (81%) and showed a recurrence in six of them (20%). According to SF-36 and GDSS, the patients' postoperative quality of life reached normal values and did not differ significantly from the standard values for the Spanish population of similar age and with similar comorbidities. Successfully operated patients reached a GIQLI value comparable to the standard population. However, symptomatic patients had significantly lower GIQLI scores than the asymptomatic or the Rx-recurrent group.

CONCLUSION

The laparoscopic treatment of large paraesophageal and mixed hiatal hernias is not only feasible and safe but also offers a good quality of life on a midterm basis. However, the anatomic and functional recurrence rate is high. The next step is to identify the subset of patients who are at risk of failure and to establish technical alternatives that would ensure the durability of the repair.

Does laparoscopic fundoplication provide long-term control of gastroesophageal reflux related cough?

BACKGROUND

Of patients with chronic cough, 21% have GERD. Up to half of these patients may not respond adequately to medical, but the long-term results of antireflux surgery for cough is unknown.

METHODS

A total of 905 patients (209 with respiratory symptoms, mainly cough) underwent laparoscopic Nissen fundoplication. Preoperatively patients underwent esophageal motility studies, 24-h pH monitoring, and symptom evaluation using a validated scale. Of eligible patients, 81% were followed at 6 months, 73% at 2 years, and 60% at 5 years.

RESULTS

Before surgery, 83% of respiratory patients (RP) and 51% of nonrespiratory patients (NRP) had cough. RP had higher cough scores ( p < 0.0001), but improvement in cough compared to baseline was similar in the RP and NRP ( p = 0.1105 at 6 months, 0.4206 at 2 years, and 0.1348 at 5 years). Cough improved in 83% at 6 months, 74% at 2 years, and 71% at 5 years.

CONCLUSIONS

Laparoscopic Nissen fundoplication is successful in the long-term control of GERD-related cough, even in patients who fail medical therapy.

Clinical outcome of laparoscopic antireflux surgery for patients with irritable bowel syndrome

BACKGROUND

The prevalence of irritable bowel syndrome (IBS) is higher among subjects with gastroesophageal reflux disease (GERD). This study aimed to assess the effect of IBS on the postoperative outcome of antireflux surgery.

METHODS

For this study, 102 patients who underwent laparoscopic fundoplication were screened preoperatively for IBS with the Rome II criteria. There were 32 patients in the IBS group and 70 patients in the non-IBS group. Most of the patients (97%) (31 of 32 IBS and 68 of 70 non-IBS patients) had both pre- and postoperative IBS evaluation. A visual analog GERD-specific scoring scale was used to evaluate GERD symptoms prospectively.

RESULTS

In both groups, GERD symptom scores were statistically improved postoperatively. Of the 31 IBS patients 25 (80.6%) showed a reduction in their symptoms below the Rome II criteria for IBS diagnosis postoperatively.

CONCLUSION

Irritable bowel syndrome does not have a negative effect on the outcome of laparoscopic antireflux surgery. Surgical correction of GERD may improve the severity of irritable bowel symptoms.

Laparoskopische Eingriffe

Many laparoscopic operations can usually be performed on an outpatient or at least short-term inpatient basis. Since the postoperative risk is easily estimated and can be determined on the 1st or 2nd postoperative day, it quickly becomes clear whether the healing process will be undisturbed or complications will occur. Prerequisites are comprehensive information to the patient as well as his cooperation and that of his social setting. From a medical standpoint, suitable administrative and infrastructural conditions must be arranged that enable safe, efficient preop preparation and guarantee reliable postoperative care of the patient. The newly begun shift in the German health care delivery system toward outpatient and short-term inpatient treatment must be introduced carefully and step by step, since the resultant reduction in postoperative inpatient care goes hand in hand with reduced patient comfort and without question places a greater burden on the patient's social setting.Clearly, optimal collaboration with local doctors is necessary to accompany this nationwide reduction in hospital stay, and the distribution of responsibility among the various physicians must be clarified. However, independently these elements, the success of outpatient and short-term inpatient laparoscopy still can be guaranteed only by surgeons' high experience and minimal complications.

Outcome of laparoscopic redo fundoplication

BACKGROUND

To date, there has been no objective evidence for the effectiveness of laparoscopic redo fundoplication. We therefore reviewed our experience and based our analysis on a number of objective parameters.

METHODS

We prospectively followed 28 consecutive patients (five men and 23 women; mean age, 48.64 +/- 2.57 years) who required redo fundoplication. These patients were part of a series of laparoscopic Nissen fundoplications done between 1992 and 2001. The indications were recurrent symptoms of gastroesophageal reflux disease (GERD) (21 patients), acute herniation of the wrap (three patients), and chronic paraesophageal hernia (four patients). A diagnosis of recurrent GERD was based on endoscopy, 24-h pH study, manometry, and symptom score evaluation. A diagnosis of paraesophageal and acute herniation was based on contrast swallow studies and/or gastroscopy.

RESULTS

Twenty-six redo fundoplications were completed laparoscopically; two were converted to open. The mean operative time was 55.43 +/- 3.81 min. There were no intraoperative complications. The mean hospital stay was 3.0 +/- 0.35 days. Postoperative complications included postoperative pneumonia in one patient. Two patients from the laparoscopic group required a third operation-one for acute herniation of the redo wrap, which was fixed laparoscopically, and the other for acute recurrent paraesophageal hernia, which was fixed via an open transthoracic approach. The mean follow-up after revision is 25.14 +/- 3.48 months, with a significant decrease in acid reflux from 5.01% +/- 0.99 to 0.48% +/- 0.23 ( p < 0.0001), a significant decrease in symptom score from 28.96 +/- 2.93 to 10.75 +/- 2.61 ( p < 0.0001), and a small but significant increase in lower esophageal sphincter (LES) pressure from 13.71 +/- 1.79 to 16.69 +/- 1.50 ( p = 0.04).

CONCLUSIONS

Laparoscopic redo fundoplication is technically feasible and clinically effective over a 2-year objective follow-up. Conversion and complication rates are low.

Laparoscopic repair of large paraesophageal hernia is associated with a low incidence of recurrence and reoperation

BACKGROUND

Laparoscopic repair of paraesophageal hernia (LRPEH) is a feasible and effective technique. There have been some recent concerns regarding possible high recurrence rates following laparoscopic repair.

METHODS

We reviewed our experience with LRPEH from 5/1996 to 8/2002. Large paraesophageal hernia (PEH) was defined by the presence of more than one-third of the stomach in the thoracic cavity. Principles of repair included reduction of the hernia, excision of the sac, approximation of the crura, and fundoplication. Pre- and postoperative symptoms were evaluated utilizing visual analogue scores (VAS) on a scale ranging from 0 to 10. Patients were followed with VAS and barium esophagram studies. Statistical analysis was performed using two-tailed Student's t-test.

RESULTS

A total of 166 patients with a mean age of 68 years underwent LRPEH. PEH were type II ( n = 43), type III ( n = 104), and type IV ( n = 19). Mean operative time was 160 min. Fundoplications were Nissen (127), Toupet (23), Dor (1), and Nissen-Collis (1). Fourteen patients underwent a gastropexy. One patient required early reoperation to repair an esophageal leak. Mean hospital stay was 3.9 days. At 24 months postoperatively there was statistically significant improvement in the mean symptom scores: heartburn from 6.8 to 0.5, regurgitation from 5.9 to 0.3, dysphagia from 4.0 to 0.5, chest pain from 3.7 to 0.3. Radiographic surveillance was obtained in 120 patients (72%) at a mean of 15 months postoperatively. Six patients (5%) had radiographic evidence of a recurrent paraesophageal hernia (two required surgery), 24 patients (20%) had a sliding hernia (two required surgery), and four patients (3.3%) had wrap failure (all four required surgery). Reoperation was required in 10 patients (6%); two for symptomatic recurrent PEH (1.2%), four for recurrent reflux symptoms (2.4%), and four for dysphagia (2.4%). Patients with abnormal postoperative barium esophagram studies who did not require reoperation have remained asymptomatic at a mean follow up of 14 months.

CONCLUSION

LPEHR is a safe and effective treatment for PEH. Postoperative radiographic abnormalities, such as a small sliding hernia, are often seen. The clinical importance of these findings is questionable, since only a small percentage of patients require reoperation. True PEH recurrences are uncommon and frequently asymptomatic.

The myth of the short esophagus

BACKGROUND

The advent of laparoscopic surgery has increased the number of fundoplications performed today. With the increase in laparoscopic fundoplications, the reports of short esophagus continue to increase. This investigation was undertaken to review our data regarding the entity described as "short esophagus."

METHOD

All charts of patients who had laparoscopic fundoplications performed from 1991 to 2000 were reviewed. Patients with laparoscopic fundoplications received esophagrams at 3 months postoperatively and then at 6 months.

RESULTS

A total of 628 fundoplications were performed, with 351 requiring hiatal hernia repair. After appropriate esophageal mobilization was performed, no further esophageal lengthening procedure was needed. There were 4 conversions, 16 recurrences, and 7 complications, and no deaths. Recurrences were due to "slipped fundoplications" ( n = 3), ineffective valves ( n = 5), and hiatal hernia disruptions ( n = 8).

CONCLUSIONS

In our series of fundoplications and hiatal hernia repairs, no short esophagus was noted. With proper esophageal mobilization, clinically the entity described as "short esophagus" may not exist.

Does the learning phase influence the late outcome of patients with gastroesophageal reflux disease after laparoscopic fundoplication?

BACKGROUND

Although the degree of surgical experience clearly affects early outcome of laparoscopic antireflux surgery, its influence on long-term results has not been fully evaluated. The aim of this study was to verify whether the initial experience in laparoscopic antireflux surgery could also influence the late clinical outcome.

METHODS

Clinical and endoscopic findings, together with quality of life, of the first 25 patients successfully submitted to laparoscopic fundoplication were compared with those of 25 matched controls operated on later.

RESULTS

At more than 2 years', follow-up, reflux symptoms, endoscopic findings, use of antisecretory drugs, side effects, and quality of life were not significantly different in both groups, despite a high occurrence of major anatomical failures (three vs one) in the first set of patients.

CONCLUSION

The late clinical outcome of patients with gastroesophageal disease operated on during the learning phase or after gaining experience is not different, provided the surgeon is adequately trained in laparoscopic surgery.

The laparoscopic experience of surgical graduates in the United States

BACKGROUND

Although laparoscopic surgery has become widespread during the past decade, no systematic study of the training needs exists. To obtain guidance for planning, we analyzed the national resident operative experience during the past 8 years.

METHODS

The laparoscopic experiences of all surgical residents graduating between 1994 and 2001 were subjected to regression analysis. The laparoscopic volume of each trainee and change in ratio of laparoscopic/open operation over time were used to estimate the growth of individual laparoscopic operations in training programs.

RESULTS

Laparoscopic surgery constituted only 5.7% of a trainee's total surgical experience in 1994, but comprised 13% by 2001. A resident completing training in 1994 performed 53 laparoscopic operations, of which 79% (42) were cholecystectomies. By 2001, a graduate performed 126 laparoscopic operations, of which 68% (86) were cholecystectomies. During the interim, most laparoscopic operations exhibited growth. Trainee experience in some newer operations has also increased steadily but at a much slower rate.

CONCLUSIONS

This descriptive statistical survey of training experience yields a comprehensive picture of the laparoscopic capability of the young surgeon. The growth potential of some newer operations has also been measured. Using these data, guidelines can be drawn as to which operation programs should focus resources on training residents. Since competence depends on exposure, residency training alone may not provide sufficient depth to allow recent graduates to perform the newer operations independently.

Utilization of laparoscopic antireflux surgery at a single Veterans Affairs facility compared with the Veterans Affairs national trend

BACKGROUND

The widespread use of laparoscopy in the early 1990s has led to an increase in the utilization of antireflux procedures for the treatment of gastroesophageal reflux disease (GERD). This trend has been observed in the private sector, but not within the Department of Veterans Affairs (VA) health care system. Published data suggest that among patients undergoing antireflux surgical procedures, those in the VA were less likely than those in the private sector to undergo laparoscopic surgery. The objective of this study was to determine the trend in the use of laparoscopic antireflux surgical procedures at our VA facility and compare it with the national VA trend.

METHODS

All antireflux operations performed at our VA facility from 1991 to 2002 were recorded along with techniques used. National VA data on the utilization of antireflux procedures from 1991 to 1999 was extracted from a recent publication by Finlayson et al.

RESULTS

In contrast to the trend observed nationally across VA hospitals, the rate of utilization of antireflux surgery at our VA facility has increased compared with baseline in 1991. Of 83 fundoplications performed from 1991 to 2002, 76 (92%) were attempted or completed laparoscopically. The conversion rate from laparoscopic to open approach was 6.6%.

CONCLUSIONS

We have observed an increase in the utilization of antireflux surgery since 1991 at our VA facility. In addition, most fundoplications were performed laparoscopically. These findings are in contrast to published national VA data. The presence of surgeons with interest in laparoscopy, institutional support, and a dedicated esophageal function laboratory may explain these findings.

Thoracoscopic Belsey fundoplication with 5-year outcomes

BACKGROUND

To determine the indications for a minimally invasive thoracic technique in gastroesophageal reflux disease (GERD), we conducted a retrospective review of outcomes with our first 21 thoracoscopic Belsey fundoplications.

METHODS

A thoracoscopic Belsey fundoplication was completed in 21 patients (12 males, 9 female; ages, 38-83 years). Preoperative evaluation revealed 13 primary motility disorders, 9 strictures, and 3 epiphrenic diverticuli. Six patients had previous gastric surgery. Sixteen patients underwent 20 ancillary procedures (esophagomyotomy, 14; excision of diverticulum, 2; lung volume reduction, 2; prosthetic diaphragmatic repair, 1; and Thal-Woodward esophagoplasty, 1).

RESULTS

Mean follow-up was 75.6 months (range, 67-85 months). There was one operative death (4.8%). Early morbidity included two esophageal leaks (9.8%). Late morbidity included three patients (15.7%) with persistent dysphagia and five patients (26%) with recurrent GERD.

CONCLUSION

Thoracoscopic Belsey fundoplication was associated with a high morbidity and recurrence rate in our long-term experience.

The respiratory advantage of laparoscopic Nissen fundoplication

BACKGROUND/PURPOSE

Laparoscopic Nissen fundoplication is replacing the open approach in the treatment of children with gastroesophageal reflux. The postoperative respiratory advantages seem obvious but remain unproven. The authors hypothesized that laparoscopic Nissen fundoplication provides postoperative respiratory advantages in neurologically normal children as well as those with mental retardation or profound neurologic impairment.

METHODS

The charts of all laparoscopic Nissen fundoplications over a 4-year period were reviewed. Sixty-one laparoscopic procedures were compared with the most recent 61 consecutive open Nissen fundoplications. The following variables were reviewed: age, weight, gender, preexisting comorbidities, operating time, postoperative pulmonary complications, and length of stay. Categorical data were compared for significance utilizing chi2 cross tabulation. Variables representing numerical data were compared by t test.

RESULTS

Although there appeared to be a trend toward sicker patients in the open group, the laparoscopic group showed significantly improved rates of extubation, shorter recovery room stays, shorter durations of chest physiotherapy, fewer intensive care unit admissions, more rapid resumption of baseline feedings, and overall decreased length of stay (P < 0.05). Pulmonary benefits also were noted in the neurologically impaired population when analyzed separately.

CONCLUSIONS

Laparoscopic Nissen fundoplication confers a definable benefit with a significant pulmonary advantage in both neurologically normal children and those with neurologic impairment.

National trends in utilization and outcomes of antireflux surgery

BACKGROUND

Studies examining the outcomes of surgery for gastroesophageal reflux disease (GERD) have consisted primarily of case series. We sought to assess trends in both utilization and outcomes of antireflux surgery from a national perspective.

METHODS

Using ICD-9 codes, we identified all antireflux procedures (N = 24,208) performed on adults from 1990 to 1997 in hospitals participating in the Nationwide Inpatient Sample, the largest all-payer inpatient care database in the United States. Using sampling weights and U.S. Census data, we then calculated the national population-based rate of antireflux surgery for each year and examined secular trends in utilization, in-hospital mortality, splenectomy (a technical complication), and length of hospital stay. Using a coding algorithm, we also assessed trends in the proportion of procedures performed via the laparoscopic, open abdominal, and thoracic approaches.

RESULTS

From 1990 to 1997, the population-based annual rate of antireflux surgery increased from 4.4 to 12.0 per 100,000 adults. A substantial increase in utilization was observed from 1993 to 1995, but annual rates before and after this period were relatively stable. Between 1990 and 1997, in-hospital surgical mortality decreased from 1.2% to 0.5% (p = 0.002), splenectomy rates decreased from 3.9% to 1.5% (p <0.001), and median length of stay decreased from 7 to 2 days (p <0.01). The proportion of antireflux procedures performed laparoscopically increased from 0.5% to 64% (p <0.001), and the proportion of procedures performed using a thoracic approach decreased from 12% to 1% (p <0.001).

CONCLUSIONS

With the dissemination of the laparoscopic approach, the population-based rate of antireflux surgery has more than doubled. At the same time, operative mortality and splenectomy risks have diminished.

Risks and benefits of surgical management of gastroesophageal reflux in neurologically impaired children

BACKGROUND

The aim of this study was to investigate the feasibility and results of laparoscopic antireflux procedure in neurologically impaired children.

METHODS

Over a 5-yr period, 259 children affected by gastroesophageal reflux disease underwent laparoscopic antireflux procedure. Eighty of them (30.8%) were neurologically impaired. In 58 children we performed an anterior fundoplication according to Thal and in 22 patients a 360 degrees fundoplication according to Nissen. Forty-eight children underwent an associated gastrostomy placement at the same time as the laparoscopic antireflux procedure.

RESULTS

We recorded 4/80 intraoperative complications; in all cases the complication was managed laparoscopically and no conversion was needed. Follow-up ranged from 6 months to 6 yrs (median 3 yrs). We recorded 24/80 postoperative complications, 5 of which required a redo procedure. We have a mortality rate of 17.5% but in only one case was the event related to the antireflux procedure.

CONCLUSIONS

Laparoscopic fundoplication can be performed safely and with acceptable results in neurologically impaired children. The indication to add a gastrostomy should be tailored to the needs of the individual patient. Mortality rate in neurologically impaired children patients with gastroesophageal reflux disease is high but in most cases unrelated to the antireflux 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.

Recurrence after laparoscopic and open Nissen fundoplication: a comparison of the mechanisms of failure

BACKGROUND

Laparoscopic Nissen fundoplication as treatment for gastroesophageal reflux disease (GERD) in adults has a reported recurrence rate of 2-17%. We investigated the rates and mechanisms of failure after laparoscopic Nissen fundoplication in children.

METHODS

All patients who underwent a laparoscopic Nissen fundoplication for GERD and who subsequently required a redo Nissen were reviewed (n = 15). The control group consisted of the most recent 15 patients who developed recurrent GER after an open Nissen, fundoplication.

RESULTS

Between 1994 and 2000, laparoscopic Nissen fundoplication was performed in 179 patients. Fifteen patients (8.7%) underwent revision. The mechanisms of failure were herniation in four patients, wrap dehiscence in four, a too-short wrap in three, a loosened wrap in two, and other reasons in two. The reoperation was performed laparoscopically in five patients (33%). The failure mechanisms were different in the open patients: eight were due to slipped wraps; three to dehiscences; and two to herniations.

CONCLUSION

The failure rate after laparoscopic Nissen is acceptably low. A redo laparoscopic Nissen can be performed safely after an initial laparoscopic approach.
