A contemporaneous comparison of hospital charges for laparoscopic and open Nissen fundoplication

Implementation of Laparoscopic Nissen Fundoplications in a Developing South African Pediatric Surgical Service

Introduction

Pediatric laparoscopic Nissen fundoplication (LNF) has become the standard approach at many centers. We developed a minimal access surgery (MAS) training curriculum to enhance the delivery of MAS for pediatric patients in a resource-limited setting. We reviewed our 10-year experience in implementing and performing LNF at our institution.

Methods

We described the challenges of implementing MAS training for LNF and how we addressed them. Beneficial technical considerations were described. A retrospective review was performed on all pediatric LNFs performed.

Results

We performed 268 LNFs. Specialists or trainees under supervision performed all LNFs. The trainee group performed 43 LNFs (16%). The median operative time for the specialists was 94 min (interquartile range [IQR] 50), and the trainee group was 140 min (IQR 62.5). The median number of cases performed until we improved operative time amongst the trainees was nine (IQR 3). There were seven repeat LNFs, and 11 cases were converted to open. The overall complication rate was 8.9%. A reduction in complications among specialists occurred over the years. The 30-day mortality post-LNF was 0.7%.

Conclusion

LNF can be successfully introduced at a tertiary training centre in South Africa with good outcomes. A comprehensive quality improvement program, including MAS training, supported this.

Cost-effectiveness of proton pump inhibitors versus laparoscopic Nissen fundoplication for patients with gastroesophageal reflux disease: a systematic review of the literature

BACKGROUND

Gastroesophageal reflux disease is a common condition in Western countries. It is unknown whether medical or surgical treatment is more cost-effective. This study was conducted to determine whether laparoscopic Nissen fundoplication or treatment by proton pump inhibitors is the most cost-effective for gastroesophageal reflux disease in the long term.

METHODS

Medline, EMBASE, and Cochrane databases were searched for articles published between January 1990 and 2010. The search results were screened by two independent reviewers for economic evaluations comparing costs and effects of laparoscopic Nissen fundoplication and proton pump inhibitors in adults eligible for both treatments. Cost and effectiveness or utility data were extracted for both treatment modalities. The quality of the economic evaluations was scored using a dedicated checklist, as were the levels of evidence.

RESULTS

Four publications were included; all were based on decision analytic models. The economic evaluations were all of similar quality and all based on data with a variety of evidence levels. Surgery was more expensive than medical treatment in three publications. Two papers reported more quality-adjusted life-years for surgery. However, one of these reported more symptom-free months for medical treatment. In two publications surgery was considered to be the most cost-effective treatment, whereas the other two favored medical treatment.

CONCLUSIONS

The results with regard to cost-effectiveness are inconclusive. All four economic models are based on high- and low-quality data. More reliable estimates of cost-effectiveness based on long-term trial data are needed.

Extracorporeal "Giant" locking sliding knot in pediatric and neonatal minimally invasive surgery: indications, techniques, and outcomes

AIM

A prospective study to assess the clinical application of extracorporeal "Giant" locking sliding knot (GLSK) in pediatric and neonatal minimally invasive surgery (MIS).

MATERIALS AND METHODS

A total of 152 MIS, of various complexities were performed over a 14-month period with more than 1100 GLSKs used in 126 procedures.

RESULTS

There were no major complications or deaths in this cohort. Unraveling of the GLSK was observed in three instances (0.3%) secondary to excessive manipulation. Only a copolymer of glycolic acid/trimethylene carbonate material (Maxon suture; Covidien, Norwalk, CT) and polyproplene (Prolene suture; Ethicon, Sommerville, NJ) can be used for the GLSK technique due to their very smooth surface.

CONCLUSION

Extracorporeal GLSKs can replace intracorporeal knots because they are safe, faster to tie, and reduce the surgeon's fatigue during complex MIS.

Locking sliding knots in laboratory model of thoracoscopic repair of esophageal atresia

AIM

The study aimed to assess feasibility and strength of locking sliding knots, in comparison to intracorporeal square knots, in a thoracoscopic model of esophageal atresia (EA).

METHODS

A simple thoracoscopic model of EA was created, and inside this model, 26 sliding knots were used to suture a soft drain together. In all cases, ten 5-0 monofilament sutures were used for this "anastomosis." The drain is then mounted on a motorized digital tensometer, and the knots with the best tension profile were retested 4 more times to obtain an average. The tensometer measured the knots' strength by producing a constant and increasing weight on the sutured EA model and continuous readings were taken by integrated computer software. The point, at which either the knot slipped, broke, or the drain disrupted, was taken as the maximum load tolerated by the sliding knots. Knot pushers were not required for any of these knots.

RESULTS

Of the 26 sliding knots, only locking sliding knots tolerated reasonably high tensions. However, when comparing these knots to the standard square knot, only Giant and Field knots had similar tension readings. Field knot was found to be very complex and therefore impractical with 5-0 suture material, leaving Giant knot as the only knot with favorable results.

CONCLUSIONS

Locking sliding knots and particularly Giant knot could have an enormous impact in minimally invasive surgery of neonatal conditions and can potentially replace intracorporeal knots. Giant knot is faster to tie and thus could reduce surgeon's fatigue during complex procedures.

Randomized clinical trial and follow-up study of cost-effectiveness of laparoscopic versus conventional Nissen fundoplication

BACKGROUND

Laparoscopic Nissen fundoplication (LNF) has essentially replaced its conventional open counterpart (CNF). An economic evaluation of LNF compared with CNF based on prospective data with adequate follow-up is lacking.

METHODS

Data from two consecutive studies (a randomized clinical trial (RCT) of 57 patients undergoing LNF and 46 undergoing CNF that was terminated prematurely, and a follow-up study of 121 consecutive patients with LNF) were combined to determine incremental cost-effectiveness 1 year after surgery.

RESULTS

Mean operating time, reoperation rate and hospital costs of LNF were lower in the second series. The mean overall hospital cost per patient was euro 9126 for LNF and euro 6989 for CNF at 1 year in the initial RCT, and euro 7782 in the second LNF series. The success rate of both LNF and CNF at 1 year was 91 per cent in the RCT, and LNF was successful in 90.1 per cent in the second series. A cost reduction of euro 998 for LNF would cancel out the cost advantage of CNF. Similarly, if the reoperation rate after LNF decreased from 0.05 to below 0.008 and/or if the mean duration of sick leave after LNF was reduced from 67.2 to less than 61.1 days, the procedure would become less expensive than CNF. Complications, reoperation rate and quality of life after both operations were similar.

CONCLUSION

Including reinterventions, the outcome at 1 year after LNF and CNF was similar. In a well organized setting with appropriate expertise, the cost advantage of CNF may be neutralized.

Anti-reflux surgery in the laparoscopic era

The introduction of laparoscopic anti-reflux surgery has led to a renewed interest in the operative treatment of gastro-oesophageal reflux disease (GORD). Three groups of patients can be identified who are particularly suited to laparoscopic anti-reflux surgery. Failure to respond to medical treatment has been historically the main determinant for those referred for anti-reflux surgery. With the availability of modern anti-secretory drugs most patients with chronic GORD can control their symptoms adequately by these means. Even effective medical therapy, however, is not without problems. In many patients rapid and consistent relapse of symptoms and oesophagitis occurs on cessation of therapy. Some of these patients do not want to be reliant on a form of medication that has yet to firmly establish its record for safety over many years of continued use. A second readily identifiable group of patients are those who are often described as 'volume refluxers'. They are bothered by persistent fluid regurgitation despite adequate control of their heartburn with acid suppressive drugs. Third there are those individuals who develop oesophageal strictures and those with Barrett's oesophagus and concomitant reflux symptoms and also those with respiratory complications associated with presumed aspiration of gastric juice into the pharynx and into the respiratory tree. The low morbidity associated with laparoscopic surgery that has been achieved in the best modern series means that the pendulum may swing back to surgery and therefore it is even more important that the right operation (fundoplication) is done for the right patient. Failure to create an adequate crural repair behind the wrap is associated with a risk of early post-operative para-oesophageal herniation and proximal wrap migration. The question of tailored anti-reflux surgery based on the pre-operative motor function of the body of the oesophagus is widely applied, although the scientific basis for these selective approaches is rather weak. Partial fundoplication seems to be associated with very low rates of dysphagia and of gas bloat. Assessment of the post-operative result should ideally be done by an independent observer and should consider not only traditional outcome measures but also the impact of surgery on the quality of the patient's life. Investigations on the cost effectiveness of these surgical therapeutic strategies suggest important benefits of surgery, which should be incorporated into the clinical decision process when assessing different long-term management alternatives for patients with chronic GORD.

Feasibility of 23-hour hospitalization after laparoscopic fundoplication

PURPOSE

In order to reduce the costs of laparoscopic fundoplication, a pilot program for outpatient surgery was instituted in 1995. The risks and benefits of reducing postoperative hospitalization to < or =23 hours were assessed.

PATIENTS AND METHODS

Patients in ASA grade I or II (N = 22) with refractory gastroesophageal reflux disease underwent laparoscopic fundoplication over a 21-month period in a hospital-affiliated outpatient facility. The results were compared with those of a similar group of 16 patients whose surgery was performed on an inpatient basis.

RESULTS

Seventeen patients (77%) were discharged within 23 hours of surgery. The maximum length of stay was 3 days. There were no deaths. Nineteen patients (86%) reported excellent results. The average facility cost declined from $7,169 for the inpatient group to $4,588 for patients on operated under the outpatient protocol. The decrease resulted from a reduction in the cost of room, operating suite, supplies, and anesthesia.

CONCLUSION

Laparoscopic fundoplication can be performed safely in a hospital-affiliated outpatient setting, resulting in a significant reduction in procedure costs.

Antireflux surgery in the laparoscopic era

BACKGROUND

The recent development of laparoscopic techniques for fundoplication has created renewed interest in surgery for gastro-oesophageal reflux disease, leading to reports of large clinical series from many centres. However, controversy remains about technical aspects of laparoscopic antireflux surgery, with no consensus yet reached about a standard operative technique. It is important, therefore, to reassess critically the results of laparoscopic surgery for reflux disease, so that its current status can be determined.

METHODS

Published outcome studies for laparoscopic antireflux surgery, as well as selected studies from the era of open antireflux surgery, were reviewed to assess outcomes.

RESULTS

The results of case series for laparoscopic antireflux surgery with short- and medium-term follow-up, as well as the early results of randomized trials, confirm that this approach reduces the early overall morbidity of surgery for reflux disease. However, certain complications may be more common, for instance paraoesophageal hiatus herniation, pneumothorax and oesophageal perforation, requiring surgeons to use specific strategies which can help to avoid these problems. Published studies and trials do not support the routine or selective application of a posterior partial fundoplication technique or routine division of the short gastric vessels during Nissen fundoplication.

CONCLUSION

At present, a short loose Nissen fundoplication performed laparoscopically, with or without division of the short gastric vessels, is an appropriate surgical approach for gastro-oesophageal reflux disease. However, long-term outcomes following laparoscopic antireflux surgery will not be available for some years, and must be awaited before the final status of the various laparoscopic techniques can be confirmed.

The treatment of gastroesophageal reflux disease with laparoscopic Nissen fundoplication: prospective evaluation of 100 patients with "typical" symptoms

OBJECTIVE

To evaluate prospectively the outcome of laparoscopic fundoplication in a large cohort of patients with typical symptoms of gastroesophageal reflux.

SUMMARY BACKGROUND DATA

The development of laparoscopic fundoplication over the past several years has resulted in renewed interest in the surgical treatment of gastroesophageal reflux disease (GERD).

METHODS

One hundred patients with typical symptoms of GERD were studied. The study was limited to patients with positive 24-hour pH studies and "typical" symptoms of GERD. Laparoscopic fundoplication was performed when clinical assessment suggested adequate esophageal motility and length. Outcome measures included assessment of the relief of the primary symptom responsible for surgery; the patient's and the physician's evaluation of outcome; quality of life evaluation; repeated upper endoscopy in 30 patients with presurgical esophagitis; and postsurgical physiologic studies in 28 unselected patients, consisting of 24-hour esophageal pH and lower esophageal sphincter manometry.

RESULTS

Relief of the primary symptom responsible for surgery was achieved in 96% of patients at a mean follow-up of 21 months. Seventy-one patients were asymptomatic, 24 had minor gastrointestinal symptoms not requiring medical therapy, 3 had gastrointestinal symptoms requiring medical therapy, and 2 were worsened by the procedure. Eighty-three patients considered themselves cured, 11 were improved, and 1 was worse. Occasional difficulty swallowing not present before surgery occurred in 7 patients at 3 months, and decreased to 2 patients by 12 months after surgery. There were no deaths. Clinically significant complications occurred in four patients. Median hospital stay was 3 days, decreasing from 6.3 in the first 10 patients to 2.3 in the last 10 patients. Endoscopic esophagitis healed in 28 of 30 patients who had presurgical esophagitis and returned for follow-up endoscopy. Twenty-four-hour esophageal acid exposure had returned to normal in 26 of 28 patients studied after surgery. Lower esophageal sphincter pressures had also returned to normal in all patients, increasing from a median of 5.1 mmHg to 14.9 mmHg.

CONCLUSIONS

Laparoscopic Nissen fundoplication provides an excellent symptomatic and physiologic outcome in patients with proven gastroesophageal reflux and "typical" symptoms. This can be achieved with a hospital stay of 48 hours and a low incidence of postsurgical complications.

[Results of fundoplication by laparoscopic approach in the treatment of gastroesophageal reflux. Apropos of 224 cases]

STUDY AIM

The aim of this paper is to evaluate prospectively immediate and 2-year results of laparoscopic fundoplicature (LF) for gastroesophageal reflux disease (GERD).

PATIENTS AND METHODS

Patients presenting GERD who had been previously submitted to a long-term medical treatment were included in this study. Preoperative workup included upper GI tract endoscopy, esophageal manometry and 24-hour pHmetry. Standard surgical procedure incorporated a Nissen-Rossetti 360 degrees fundoplicature. Short vessels division (Nissen operation) was performed in case of high strength of the wrap and a partial fundoplicature (Toupet 270 degrees) was performed when motility disorders of the esophagus were demonstrated by manometry. Postoperative morbidity and results were evaluated, with a clinical appreciation at 3 and 22 months, and by manometry and pHmetry at 3 months.

RESULTS

Two hundred and thirty-five patients were observed, and 224 included in the study (143 men and 92 women). Nissen-Rossetti fundoplication was performed in 169 cases (80%), Nissen in 30 (14%) and Toupet in 13 (6%). In 12 cases (5%). LF was converted to an open Nissen-Rossetti procedure. There was no hospital mortality and complications were noted in three cases (1.5%): pneumonia (n = 2) and gastroplegia (n = 1). With a mean 22-month follow up, among the 103 patients who answered to a questionnaire, the rate of relapse of GERD was 14%, dysphagia was present in 2% and four patients had been reoperated on (one for a slipped Nissen, one for a stenosis of the esogastric junction and two incisional hernias).

CONCLUSION

On the basis of this experience, LF for GERD is a safe and efficient operation, with 86% of good results at 2 years.

Early experience and learning curve associated with laparoscopic Nissen fundoplication

BACKGROUND

Laparoscopic approach for hiatal hernia repair is relatively new. Information on the learning curve is limited.

METHODS

From January 1994 to September 1996, 280 patients underwent antireflux surgery at our institution. A laparoscopic repair was attempted in 60 patients (21.4%). There were 38 men and 22 women. Median age was 49 years (range 21 to 78 years). Indications for operation were gastroesophageal reflux in 59 patients and a large paraesophageal hernia in one. A Nissen fundoplication was performed in all patients; 53 (88.3%) had concomitant hiatal hernia repair.

RESULTS

In eight patients (13.3%) the operation was converted to an open procedure. Median operative time for the 52 patients who had laparoscopic repair was 215 minutes (range 104 to 320 minutes). There were no deaths. Complications occurred in five patients (9.6%). Median hospitalization was 2 days (range 1 to 5 days). Median operative time and median hospitalization were significantly longer in the first 26 patients than in the subsequent 25 patients (248 vs 203 minutes and 2 days vs 1 day, respectively; p = 0.03). Seven of the first 30 patients (23.3%) required laparotomy as compared with two of the second 30 (6.7%) (p = 0.07). Follow-up in the 51 patients who had laparoscopic fundoplication for reflux was complete in 50 (98.0%) and ranged from 7 to 38 months (median 13 months). Functional results were classified as excellent in 34 patients (68.0%), good in 6 (12.0%), fair in 7 (14.0%), and poor in 3 (6.0%). Three patients were reoperated on for recurrent reflux symptoms at 5, 5, and 11 months.

CONCLUSIONS

We conclude that laparoscopic Nissen fundoplication can be performed safely. The operative time, hospitalization, and conversion rate to laparotomy are higher during the early part of the experience, but all are reduced after the learning curve.

Experimental development of an endoscopic approach to neck exploration and parathyroidectomy

BACKGROUND

Recent advances in minimally invasive surgical technology have the potential to lead to new applications outside body cavities. The purpose of the present study was to develop techniques for obtaining endoscopic exposure and access to the pretracheal space in the neck with the goal of performing neck exploration and parathyroidectomy and to evaluate the safety and efficacy of such an approach experimentally.

METHODS

The technique for endoscopic neck exploration was developed in eight adult mongrel dogs and was further evaluated in a survival dog model and in human cadavers. The pretracheal space was accessed by a 2.5 cm midline incision in the lower neck. This space was expanded with a balloon dissector, and exposure was maintained with an external lift device. A 5 or 10/12 mm midline port and two to four lateral 5 mm cervical ports were placed, and dissection was carried out with pediatric endoscopic instruments and an ultrasonic coagulator. Excised parathyroid tissue was verified histologically.

RESULTS

Two-gland parathyroidectomy was successfully completed in five of six dogs; inadequate exposure led to a failed procedure in one animal. Mean operative time was 130 +/- 6 minutes, and there were no operative complications. Serum calcium levels did not change significantly after operation (p = not significant). At autopsy, approximately 20 ml of clear sterile fluid was present in the pretracheal space of every dog. In five human cadavers mean dissection time for attempted four-gland parathyroidectomy was 69 +/- 38 minutes (range, 45 to 135 minutes). Four of four parathyroids were identified and removed in two patients, three of three parathyroids in one patient, three of four parathyroids in one patient, and two of four parathyroids in one patient.

CONCLUSIONS

Parathyroidectomy may be performed safely and reliably in an animal model with minimally invasive techniques that can be applied to parathyroid dissection in human cadavers. These results suggest that an endoscopic approach to neck exploration and parathyroidectomy is potentially feasible and may warrant further study in clinical trials.

Laparoscopic adrenalectomy. A new standard of care

OBJECTIVE

The authors review their experience with laparoscopic adrenalectomy in patients with benign adrenal neoplasms. Efficacy, safety, and cost effectiveness of the procedure are examined.

BACKGROUND

Laparoscopic adrenalectomy is replacing open adrenalectomy in some medical centers as the standard surgical approach for uncomplicated tumors. However, laparoscopic adrenalectomy often is considered more difficult and more expensive than traditional "open" surgery.

METHODS

Perioperative and postoperative records as well as hospital charges from the first 19 patients undergoing laparoscopic unilateral adrenalectomies at the authors' medical institutions were examined and compared with 19 patients who underwent open unilateral adrenalectomies.

RESULTS

None of the 19 patients undergoing unilateral laparoscopic adrenalectomy required conversion to open adrenalectomy. Mean operative times as well as total hospital charges were similar in those patients undergoing either laparoscopic or open adrenalectomy. However, the morbidity and postoperative length of hospital stay were significantly less in those patients undergoing laparoscopic adrenalectomy.

CONCLUSIONS

Laparoscopic adrenalectomy can be performed safety and with the benefits associated with minimally invasive surgery. In addition, the procedure is cost effective. These factors suggest that laparoscopic adrenalectomy should be the preferential surgical technique for benign adrenal disease.

Comparative analysis of laparoscopic versus open splenectomy

BACKGROUND

Laparoscopic splenectomy (LS) has been used to treat a variety of splenic disorders. However, there have been few direct comparisons of this approach with open splenectomy (OS).

METHODS

Results and outcomes were compared retrospectively in 46 consecutive patients treated by laparoscopic (n = 26) or open splenectomy (n = 20) from January 1990 through March 1996. The two groups were similar in age, sex, and American Society of Anesthesiology classification. Splenectomy was performed for a variety of indications, and the majority of patients in both groups had normal or near-normal size spleens. All data are expressed as mean +/- standard deviation.

RESULTS

Laparoscopic splenectomy was successfully completed in all 26 attempted cases. Operative times were significantly longer for LS (202 +/- 55 minutes) than for OS (134 +/- 43 minutes) (P < 0.001); however, operative times in the last 13 LS cases (176 +/- 48 minutes) averaged 51 minutes less than in the first 13 cases (227 +/- 51 minutes). Estimated operative blood loss was less for LS (222 +/- 280 mL) than for OS (376 +/- 500 mL) (P = not significant). A mean of 2.0 units of red blood cells was transfused in 4 (15%) of 26 patients during LS vs 1.0 unit transfused in 2 (10%) of 20 patients who had OS (P = NS). Patients who underwent LS required significantly less parenteral pain medications, had a more rapid return to regular diet, and were discharged sooner than patients who had OS. Complication rates were similar in the two groups.

CONCLUSIONS

These results suggest that LS is technically safe and has several advantages over OS. Laparoscopic splenectomy should become the procedure of choice for the removal of normal and near-normal size spleens.

Laparoscopic Nissen fundoplication is less expensive than open Belsey Mark IV

Laparoscopic Nissen fundoplication is a relatively new technique used to treat gastroesophageal reflux disease (GERD). The purpose of this study was to compare the cost to the patient and insurer of a laparoscopic Nissen fundoplication (LN) to an open Belsey Mark IV (B4), the previous standard operation for GERD at Emory University Hospital. A retrospective review of 20 consecutive patients undergoing LN or B4 for GERD was performed. Patients were well matched for age, severity of disease, and comorbid illness. The data were analyzed using an unpaired Student's t-test or Wilcoxon signed rank analysis. The results are as follows (mean +/- SD): [table: see text] We conclude that the charges for laparoscopic Nissen fundoplication are significantly less than the charges for Belsey Mark IV. The majority of the savings resulted from a shortened hospital stay.
