The economics of laparoscopic Nissen fundoplication

BACKGROUND & AIMS

A major impetus for laparoscopic Nissen fundoplication (LNF) is its purported cost savings compared with medical therapy, but few studies have examined these economic outcomes. The aim was to analyze health care costs and use among a cohort of patients undergoing LNF and compare them with patients with medically treated gastroesophageal reflux disease (GERD).

METHODS

Comparison of health care use and direct costs from the third-party payer perspective using 13 United HealthCare Plans. Sixty-one patients who underwent LNF from January 1994 to June 1998 and 178 matched controls were used for this study. Outcome variables included the cost of hospital and outpatient visits, hospitalizations, related endoscopic procedures, and pharmacy claims for proton pump inhibitors, H(2) receptor antagonists, and prokinetics. Cost of LNF or index esophagogastroduodenoscopy was not included.

RESULTS

Sixty-one LNF patients and 178 controls were studied. No differences were seen for the costs of office visits and hospital admissions or the number of gastrointestinal procedures. LNF patients had significantly lower gastrointestinal medication costs. Median total health care costs were significantly lower in the LNF group but mean total costs were not different. This was attributable to $201,000 in costs for managing complications in one patient that skewed total health care cost in the LNF group.

CONCLUSIONS

For the 12 months after surgery, LNF reduced costs for gastrointestinal medications but not total costs for the cohort. LNF cost is impacted greatly by the cost of associated complications. Based on these data, LNF does not appear to significantly reduce the direct cost of health care for GERD patients on a population basis.

Motion--Laparoscopic Nissen fundoplication is more cost effective than oral PPI administration: arguments against the motion

Discussion of the cost effectiveness of medical and surgical treatments of gastroesophageal reflux disease (GERD) is plagued by a number of logical fallacies. Several of these defects in reasoning are reviewed. For example, it is inappropriate to compare the costs of therapies unless they are equally effective. The relative cost effectiveness of various treatment options is difficult to determine because monetary expenditures and gains in health status cannot easily be measured in commensurate units. Not everything can be translated into incremental cost effectiveness ratios. Two decision analyses from European investigators seemed to show that Nissen fundoplication was more cost effective than long term acid-suppression therapy, but they failed to consider the costs of surgical complications and failures. The most comprehensive decision analysis, employing a Markov chain model, found that the two treatment options were roughly equivalent, at least during the first seven years of follow-up. Decision analyses often do not reflect actual practice patterns and cannot provide solutions to problems that cannot be solved by appropriate medical reasoning. Moreover, results that are reported by specialized surgical centres probably cannot be duplicated by less experienced surgeons. The increasing incidence of esophageal adenocarcinoma has been erroneously attributed to the use of potent acid-suppressant medications, but the actual cause has been shown to be the decreased prevalence of Helicobacter pylori. There are no significant differences in the incidence of this tumour after medical or surgical therapy of GERD. It is unlikely, however, that arguments will convince proponents of one treatment or another to change their opinions.

Laparoscopic antireflux procedures in children: evaluating the evidence

A growing number of the pediatric antireflux procedures are performed laparoscopically. Although there are no prospective randomized studies comparing conventional open surgery to laparoscopic surgery, there are retrospective and anecdotal data suggesting that the laparoscopic approach is at least as good and, in many cases, better than the open procedure. Once the significant learning curve is achieved, one may attain similar operative times with the benefit of magnification and enhanced visualization of the operative field compared to open surgery. The greatest benefits of laparoscopic antireflux surgery are the cosmetic result, a decrease in postoperative analgesia requirements, and an earlier return to normal daily life for both parents and their children.

Motion--Laparoscopic Nissen fundoplication is more cost effective than oral PPI administration: arguments for the motion

Gastroesophageal reflux disease is a mechanical disorder of the foregut. While medications can only provide symptom relief, surgery can correct the pathophysiological abnormality of the lower esophageal sphincter. The costs of medical and surgical therapy are much greater than the costs of medication or hospitalization alone. In the case of medical therapy, one must consider the costs of serial monitoring and of failed treatment. The effectiveness of treatment also depends on patient-related factors, including weight, socioeconomic factors, smoking, alcohol use, dietary habits and the use of nonsteroidal anti-inflammatory drugs. Surgical results depend on the experience and skill of the surgeon, as well as the attributes of the institution in which the procedure is undertaken. Therefore, studies that come from specialized centres may not be applicable to the community. Data from the author's facility indicate that laparoscopic Nissen fundoplication is the most cost effective option when it is undertaken by experienced surgeons on otherwise healthy patients who have documented gastroesophageal reflux disease.

Medical or surgical therapy for erosive reflux esophagitis: cost-utility analysis using a Markov model

OBJECTIVE

To compare the cost and utility of healing and maintenance regimens of omeprazole and laparoscopic Nissen fundoplication (LNF) in the framework of the Canadian medical system.

SUMMARY BACKGROUND DATA

Medical therapy with proton pump inhibitors for endoscopically proven reflux esophagitis is a safe and effective treatment option. Of late, the surgical treatment of choice for this disease has become LNF.

METHODS

The authors' base case was a 45-year-old man with erosive reflux esophagitis refractory to H2-blockers. A cost-utility analysis was performed comparing the two strategies. A two-stage Markov model (healing and maintenance phases) was used to estimate costs and utilities with a time horizon of 5 years. Discounted direct costs were estimated from the perspective of a provincial health ministry, and discounted quality-of-life estimates were derived from the medical literature. Sensitivity analyses were performed to test the robustness of the model to the authors' assumptions and to determine thresholds. A Monte Carlo simulation of 10,000 patients was used to estimate variances and 95% interpercentile ranges.

RESULTS

For the 5-year period studied, LNF was less expensive than omeprazole (3519.89 dollars vs. 5464.87 dollars per patient) and became the more cost-effective option at 3.3 years of follow-up. The authors found that 20 mg/day omeprazole would have to cost less than 38.60 dollars per month before medical therapy became cost effective; conversely, the cost of LNF would have to be more than 5,273.70 dollars or the length of stay more than 4.2 days for medical therapy to be cost effective. Estimates of quality-adjusted life-years did not differ significantly between the two treatment options, and the incremental cost for medical therapy was 129,665 dollars per quality-adjusted life-years gained.

CONCLUSIONS

For patients with severe esophagitis, LNF is a cost-effective alternative to long-term maintenance therapy with proton pump inhibitors.

Early experiences of robotic surgery in children

BACKGROUND

Laparoscopic surgery using a robotic system (Da Vinci) was recently introduced into surgical practice for adult patients. To investigate the feasibility of this system in pediatric surgery, laparoscopic fundoplication (Thal and Nissen), cholecystectomy, and bilateral salpingo-oophorectomy were performed.

METHODS

Eleven children with a mean age of 12 years (range, 7-16 years) underwent either laparoscopic anterior partial fundoplication (Thal, n = 8) or Nissen fundoplication (n = 3) for correction of gastroesophageal reflux disease in the presence of uncontrolled symptoms of regurgitation and pulmonary infection. Two children underwent laparoscopic cholecystectomy due to symptomatic cholecystolithiasis. One child underwent bilateral salpingo-oophorectomy due to a gonadoblastoma.

RESULTS

Mean operating time for fundoplication was 146 min (range, 105-180 min), the operating times for cholecystectomy were 150 and 105 min, and that for salpingo-oophorectomy was 95 min. No complications were registered during either the robotic procedures or the postoperative courses.

CONCLUSIONS

Compared to conventional laparoscopy, the three-dimensional high-quality vision, advanced instrument movement, and improved ergonomic position of the surgeon appear to enhance surgical precision. Robotic surgery in children using the Da Vinci system seems to be feasible and safe. However, the technique is limited due to the fact that instruments adapted to the size of small children are not available. Furthermore, the high costs and prolonged system setup are disadvantages.

Economic implications of current surgical management of gastroesophageal reflux disease

BACKGROUND/PURPOSE

Surgical management of gastroesophageal reflux disease in children has evolved with the development of laparoscopy. Because concerns persist regarding increased costs associated with this technique, the authors studied the economic parameters of antireflux surgery at their institution.

METHODS

Seventy-eight patients undergoing either laparoscopic or open fundoplication were studied retrospectively between June 1998 and June 2000 comparing average operating room costs, total inpatient costs, and length of stay. Univariate comparisons were performed using Student's t test, and multivariate analysis was performed using multiple linear regression.

RESULTS

Univariate analysis showed that patients receiving the laparoscopic procedure had significantly shorter inpatient stays (2.4 v. 3.96 days; P =.004) than those receiving open procedures. Average operating room costs were similar (laparoscopic, $2,611; open, $2,162; P =.237), but total costs for the laparoscopic procedure were lower ($4,484 v $5,129; P =.006). Multivariate analysis results suggested that in addition to procedure type, patients who required an intensive care unit admission incurred $6,595 in additional total costs (P <.0001) and 4.8 additional hospital days (P <.0001). After controlling for other variables, the laparoscopic procedure did not significantly reduce total hospital costs ($447; P =.192) but was associated with a significant decrease in length of stay of 1.3 days (P <.0001).

CONCLUSION

These results suggest that laparoscopic procedures are comparable with open operations in terms of operative costs and that other factors are important determinants of the costs associated with antireflux surgery in children.

Fundoplication and gastrostomy versus image-guided gastrojejunal tube for enteral feeding in neurologically impaired children with gastroesophageal reflux

BACKGROUND

Neurologically impaired children with gastroesophageal reflux (GER) usually are treated with a fundoplication and gastrostomy (FG); however, this approach is associated with a high rate of complications and morbidity. The authors evaluated the image-guided gastrojejunal tube (GJ) as an alternative approach for this group of patients.

METHODS

A retrospective review of 111 neurologically impaired patients with gastroesophageal reflux was performed. Patients underwent either FG (n = 63) or GJ (n = 48). All FGs were performed using an open technique by a pediatric surgeon, and all GJ tubes were placed by an interventional radiologist.

RESULTS

The 2 groups were similar with respect to diagnosis, age, sex and indication for feeding tube. Patients in the GJ group were followed up for an average of 3.11 years, and those in the FG group for 5.71 years. The groups did not differ statistically with respect to most complications (bleeding, peritonitis, aspiration pneumonia, recurrent gastroesophageal reflux [GER], wound infection, failure to thrive, and death), subsequent GER related admissions, or cost. Children in the GJ group were more likely to continue taking antireflux medication after the procedure (P <.05). Also, there was a trend for GJ patients to have an increased incidence of bowel obstruction or intussusception (20.8% v 7.9%). Of the FG patients 36.5% experienced retching, and 12.7% experienced dysphagia. Eighty-five percent of patients in the GJ group experienced GJ tube-specific complications (breakage, blockage, dislodgment), and GJ tube manipulations were required an average of 1.68 times per year follow-up. Nine patients (14.3%) in the FG group had wrap failure, with 7 (11.1%) of these children requiring repeat fundoplication. In the GJ group, 8.3% of patients went on to require a fundoplication for persistent problems. A total of 14.5% of GJ patients had their tube removed by the end of the follow-up period because they no longer needed the tube for feeding.

CONCLUSIONS

Image-guided gastrojejunal tubes are a reasonable alternative to fundoplication and gastrostomy for neurologically impaired children with GER. The majority can be inserted without general anesthesia. This technique failed in only 8.3% patients, and they subsequently required fundoplication. A total of 14.5% of GJ patients showed some spontaneous improvement and had their feeding tube removed. Each approach, however, still is associated with a significant complication rate. A randomized prospective study comparing these 2 approaches is needed.

The cost of long term therapy for gastro-oesophageal reflux disease: a randomised trial comparing omeprazole and open antireflux surgery

BACKGROUND AND AIM

To comprehensively assess the relative merits of medical and surgical therapy for gastro-oesophageal reflux disease (GORD), health economic aspects have to be incorporated. We have studied the direct and indirect costs of medical and surgical therapy within the framework of a prospective randomised multicentre trial.

METHODS

After initial treatment of reflux oesophagitis with omeprazole to control symptoms and to heal oesophagitis, 154 patients were randomised to continue treatment with omeprazole (20 or 40 mg daily) and 144 patients to have an open antireflux operation (ARS). In case of GORD relapse, patients allocated to omeprazole were offered ARS and those initially operated on had either a reoperation or were treated with omeprazole. The costs were assessed over five years from randomisation.

RESULTS

Differences in cumulative direct medical costs per patient between the two therapeutic strategies diminished with time. However, five year direct medical costs per patient when given omeprazole were still significantly lower than for those having ARS in Denmark, Norway, and Sweden (differences were DKK 8703 (US$1475), NOK 32 992 (US$ 5155), and SEK 13 036 (US$ 1946), respectively). However, in Finland the reverse was true (the difference in favour of ARS amounted to FMK 7354 (US$ 1599)). When indirect costs (loss of production due to GORD related sick leave) were also included, the cost of surgical treatment increased substantially and exceeded the cost of medical treatment in all countries.

CONCLUSIONS

The total costs of medical therapy for chronic GORD were lower than those of open ARS when prospectively assessed over a five year period, although significant differences in cost estimates were revealed between countries.

What did the laparoscopic Nissen approach of the gastro-oesophageal reflux really change for the patients 8 years later?

BACKGROUND

Nissen fundoplication (NF) is recognized as the surgical treatment of the gastro-oesophageal reflux disease (GERD). NF can be achieved either by open surgery or by laparoscopic approach.

METHODS

From 1987 to 1997, 210 patients were treated for GERD by NF: 61 by open and 149 by laparoscopic approach. All the patients were followed more than 1 year and were scored by clinical assessment (Visick scale adaptation). In case of Visick score > 1, GI-endoscopy, X-ray series or 24-hour pH-study complete the evaluation.

RESULTS

The operative time was comparable between both groups. The postoperative recovery was statistically faster in the laparoscopic group (p = 0.0001). The mean time of follow-up was 6 years after open NF and 4 years after laparoscopic NF. After open NF or laparoscopic NF, 72% and 67% of the patients are respectively scored Visick 1, 13% and 21%--Visick 2, 6.8% and 6%--Visick 3 and 8.2% and 6%--Visick 4 (NS). Patients with recurrence of GERD were scored Visick 4, so failure of the surgical treatment is observed in 5 patients after open NF and 9 patients after laparoscopic NF. The occurrence of incisional hernia was significantly higher in the open group (p = 0.0001).

CONCLUSION

NF remains a safe procedure for surgical treatment of GERD and can be achieved by laparoscopic approach with comparable results to those by open laparotomy. In our experience, the advantages of the laparoscopic approach is a faster postoperative recovery and a lower risk of incisional hernia.

The economics of laparoscopic antireflux operations compared with open surgery

In Sweden laparoscopic antireflux surgery started in 1991, and within four years replaced the open procedure as the method of choice. It is, however, not yet settled which of the two techniques is most cost effective. To compare these two operations in economic terms we studied all reports up to September 1997 as well as the register in the epidemiological unit of the National Board of Health and Welfare (EpC). We found numerous reports on consecutive series of laparoscopic procedures, several non-randomised studies, and only one randomised prospective study comparing open and laparoscopic antireflux surgery. The few studies about the economics of antireflux surgery indicated that hospital costs were equal or less for the laparoscopic procedure. If one adds the costs from loss of production (sick leave) it will be an even more favourable outcome for the laparoscopic treatment. The figures from EpC showed that antireflux surgery is done infrequently in many surgical departments. This may have a substantial influence on the economic outcome as well as the effectiveness of antireflux surgery in Sweden. Few studies have compared open and laparoscopic methods from an economic perspective. As a tool for cost benefit analysis these reports are incomplete.

Current medical and surgical treatment options for gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is one of the most common disorders in medicine. The options of medical versus surgical therapies have been highlighted by more potent acid suppression medications and by the introduction of minimally invasive surgery for GERD. Many factors will impact on the treatment selection for each individual patient: the underlying pathophysiology, typical vs atypical symptoms, presence of reflux complications, and success and limitations of medical and surgical treatments. Medical antireflux therapy is very effective and safe, but long-term maintenance therapy is required for most patients. Minimally invasive antireflux surgery has provided excellent results, but outcome is dependent on patient selection and surgical expertise. Careful pre-operative evaluation is essential to determine the optimal treatment and surgical approach.

A cost-minimization analysis of alternative treatment strategies for achalasia

OBJECTIVE

The aim of this study is to compare the costs per cure of alternative strategies for the treatment of achalasia.

METHODS

A cost-minimization model compared three strategies for otherwise healthy adults of any age with achalasia: 1) laparoscopic Heller myotomy with fundoplication (LHM); 2) pneumatic dilation (PD), with LHM reserved for treatment failures; 3) botulinum toxin (Botox) injection of the lower esophageal sphincter, with PD reserved for treatment failures. Probabilities of short- and long-term efficacy, treatment failure, symptomatic recurrence rates, and complications were derived from the published literature. Only direct costs were considered during the 5-yr time horizon.

RESULTS

Respective reference case costs per cure of PD, Botox, and LHM strategies were $3,111, $3,723, and $10,792. Despite short- and long-term efficacy of 96% and 94%, respectively, the LHM strategy was most costly. Initial PD remained less costly than initial Botox, provided that rates of PD efficacy and perforation were > or = 70% and < 9.5%, respectively, and cost of a Botox session was > or = $450. The results were not sensitive to the probabilities of short- and long-term response to Botox, recurrence after PD, LHM efficacy, and post-LHM gastroesophageal reflux disease, nor to the costs of LHM and PD.

CONCLUSIONS

For otherwise healthy patients with achalasia, initial PD is the least costly strategy provided that the PD perforation rate remains < 10%. Initial Botox is less costly only when nonendoscopic-related costs decrease by 25%. Initial LHM is the most costly strategy under all clinically plausible scenarios. Subsequent analyses should include a longer time horizon and an assessment of patient ference for each strategy.

[Laparoscopic surgery--evidence-based ?]

The literature has been searched for current results in laparoscopic cholecystectomy, hernia repair, appendectomy and fundoplication. This was performed as a systematic review. Laparoscopic cholecystectomy was judged to be safe and cost/effective, with good patient acceptability. However a need for further studies is indicated. Laparoscopic technique in hernia repair has a longer learning curve and is more expensive than open repair, with no major difference in recurrence rates. It is preferable in bilateral repairs. Laparoscopic appendectomy in the hands of experienced surgeons is cost/effective. Time to recovery is shorter and the rate of infectious complications is lower than in conventional procedures. There are still too few results reported from laparoscopic fundoplication to permit reliable conclusions.

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.

Current state, techniques, and results of laparoscopic antireflux surgery

The introduction of laparoscopic fundoplication has dramatically changed the face of antireflux surgery. Central to the success of laparoscopic fundoplication is careful preoperative patient evaluation and attention to surgical technique. Emerging evidence has questioned the long-term durability of laparoscopic partial fundoplications underscoring the place of laparoscopic Nissen fundoplication as the procedure of choice for most patients. The technique of laparoscopic Nissen fundoplication should incorporate crural closure, complete fundic mobilization by short gastric vessel division, and the creation of a short, loose fundoplication by enveloping the anterior and posterior fundic walls around the esophagus. Relief of typical reflux symptoms can be anticipated in over 90% of patients. The outcome of atypical reflux symptoms is less predictable, on average two thirds of patients benefiting. The cost of laparoscopic fundoplication compares favorably to long-term medical therapy and open fundoplication. Current trends indicate that laparoscopic fundoplication is being used increasingly as an alternative to long-term medical therapy.

Cost-effectiveness of laparoscopy in children

BACKGROUND

Laparoscopy may offer fast recovery and improved cosmesis, but its cost has been perceived as excessive.

OBJECTIVE

To analyze the total hospital costs of laparoscopy vs open surgery.

DESIGN

Retrospective cost-effectiveness analysis evaluating all cases performed in a 36-month period (September 1995 to August 1998). Cases were evaluated for operative time, itemized cost of supplies, and length of hospitalization.

SETTING

Operations performed by pediatric surgeons in a tertiary care children's hospital.

PATIENTS

Consecutive children undergoing laparoscopic or open appendectomies, cholecystectomies, fundoplications, and splenectomies. Patients were not randomized to laparoscopy, or open surgery.

INTERVENTIONS

Laparoscopic procedures performed with a core set of reusable equipment and a limited number of disposable instruments.

MAIN OUTCOME MEASURES

Cost surplus of laparoscopy was evaluated, and compared with savings associated with decreased hospital stay, to obtain cost-effectiveness of laparoscopy per procedure.

RESULTS

There were 26 laparoscopic and 359 open appendectomies; 33 laparoscopic and 3 open cholecystectomies; 16 laparoscopic and 18 open fundoplications; and 16 laparoscopic and 7 open splenectomies. Excess operating costs per procedure were $442.00 for appendectomy, $634.60 for fundoplication, $847.50 for cholecystectomy, and $1551.30 for splenectomy. Hospital stay was decreased for all laparoscopies, resulting in an overall savings per laparoscopic procedure of $2369.90 for appendectomy, $5390.90 for fundoplication, $1161.00 for cholecystectomy, and $858.90 for splenectomy.

CONCLUSIONS

Laparoscopy is cost-effective, particularly for fundoplication, appendectomy, and cholecystectomy. Detailing the costs of supplies, operating time, and length of stay allows interinstitutional comparison and critical cost-analysis of laparoscopy. With a more selective use of reusable instruments and further shortening of operative time, the global savings of laparoscopy may increase.

[Use of the harmonic scalpel (Ultracision) in laparoscopic antireflux surgery]

Gastroesophageal reflux disease can effectively be treated by laparoscopic fundoplication. A new multifunctional device has recently been introduced, Ultracision (UC), which can be expected to be especially effective in laparoscopy. Since 9/1995 laparoscopic fundoplication is being performed at our institution. We routinely divide the "short-gastric vessels" and have been using clip-appliers and Endo-GIAs before dividing the vessels with endo-scissors. Since 2/1997 we also use the UC, which applies ultrasonic energy to cause denaturing of proteins and subsequent hemostasis and dissection. This open, non-randomized study compares operative time, intra- and postoperative complications and conversion rates as well as costs of both methods. Between 2/1997 and 12/1997 20 consecutive patients received a floppy Nissen fundoplication by 2 surgeons. In 8 patients clips/EndoGIA were used (m:w = 5:3, mean age 52 years [33-69]), in 12 patients UC (m:W = 10:2, 53 years [25-74]) was used. 2 patients in each group had had previous open abdominal surgery. In the first group 2 procedures had to be converted to open surgery (1 bleeding, 1 anatomical problem), median operative time was 214 min (135-360). In the UC group all procedures were completed laparoscopically, median operative time 132 min (75-240). Postoperative major complication and mortality rates were 0 in both groups. Use of the harmonic scalpel reduced operative time and costs without increasing conversion rates and perioperative complications.

Comparison of costs between laparoscopic and open Nissen fundoplication: a prospective randomized study with a 3-month followup

BACKGROUND

Laparoscopic antireflux surgery has replaced conventional operation despite the fact that currently no randomized trials have been published regarding its cost effectiveness. The objective of the present study was to compare costs and some short-term outcomes of laparoscopic and open Nissen fundoplication.

STUDY DESIGN

Forty-two patients with documented gastroesophageal reflux disease were randomized between October 1995 and October 1996 to either laparoscopic (LNF) or open (ONF) Nissen fundoplication. Some short-term outcomes, Gastrointestinal Quality of Life Index (GIQLI) hospital costs, and costs to society were assessed. Followup was 3 months.

RESULTS

Medians of operation times in the LNF and ONF groups were 98 min and 74 min, respectively. Hospital stay was 2.5 days shorter after laparoscopic operation (LNF 3 days versus ONF 5.5 days). Both operations were equally safe and effective, but the LNF group experienced significantly less pain and fatigue during the first 3 postoperative weeks. Improvement in the GIQLI and overall patient satisfaction were comparable between the methods. Convalescence was faster in the LNF group: return to normal life being 14 versus 31 days and return to work being 21 versus 44 days in the LNF and ONF groups, respectively. Hospital costs were similar, $2,981 and $3,140 in the LNF and ONF groups, respectively, but total costs were lower ($7,506 versus $13,118) in the LNF group as a result of an earlier return to work.

CONCLUSIONS

LNF is superior in cost effectiveness, assuming that the longterm results between the methods are comparable.

Early laparoscopic Nissen fundoplication for recurrent reflux esophagitis: a cost-effective alternative to omeprazole

BACKGROUND

Eighty percent of patients treated medically for gastroesophageal reflux disease relapse after treatment. Many of these patients require indefinite treatment with omeprazole to prevent recurrence. Nissen fundoplication has been shown to be effective, safe and cost effective in the management of gastroesophageal reflux disease. We suggest a treatment algorithm, which encourages early surgical intervention in cases of recurrent esophagitis after a previously successful two-month course of omeprazole.

METHODS

We have offered laparoscopic Nissen fundoplication since 1993. Patients who received Nissen fundoplication since 1990 were asked to report return to baseline activity, medications, and lifestyle changes. Concurrent chart review of patients treated with omeprazole was conducted to analyze cost.

RESULTS

Patients receiving laparoscopic Nissen fundoplication were discharged significantly sooner and spent significantly less time convalescing when compared to those who underwent open Nissen fundoplication. Laparoscopic Nissen fundoplication became cost effective at 1.5 to 2 years when compared to omeprazole.

CONCLUSION

Based on cost analysis, patient satisfaction, acceptable complication rate, and efficient use of time and resources, we recommend laparoscopic Nissen fundoplication as the appropriate treatment in patients who develop recurrent esophagitis after a two-month treatment with omeprazole.

Laparoscopic or open fundoplication? A complete cost analysis

BACKGROUND

As part of a prospective observational trial, we set out to determine the direct and indirect costs of an open versus a laparoscopic fundoplication for chronic gastroesophageal reflux disease (GERD).

METHODS

Two groups of patients, each comprising 28 subjects, were studied.

RESULTS

All patients received a functioning fundoplication that did not require any additional therapy. Because 19 and 12 patients in the open and laparoscopy groups, respectively, were employed in the work force, we were able to assess the costs due to loss of production. The mean operating time was similar for both groups, but postoperative stay differed significantly; though it amounted to 8 days for the open group, it was only 2 days for the laparoscopy group. Postoperative sick leave was 29.9 days in the open and 9.9 in the laparoscopy group (p < 0.05). The costs of the operations were 18,363 SEK for laparoscopy and 12,856 SEK for conventional fundoplication. On the other hand, the cost for hospital stay amounted to 35,488 SEK in the open group but was only 25,571 SEK for those undergoing laparoscopy. When we add outpatient visits, endoscopies, and other medical expenses, the total direct costs in the laparoscopy group come to 27,693 SEK, as compared to 37,482 SEK for the open fundoplication. The indirect medical costs, which were dominated by loss of production (36,732 versus 12,126 SEK), came to 37,126 and 12,595 SEK in the open and laparoscopy groups, respectively.

CONCLUSIONS

The total community-based costs for the open and laparoscopic operations for chronic GERD amounted to 74,608 and 40,289 SEK, respectively. Thus, we would recommend the laparoscopic procedure in most cases.

Quality of life and antireflux medication use following laparoscopic Nissen fundoplication

With the advent of minimally invasive techniques, the surgical treatment of gastroesophageal reflux disease has received renewed interest. The efficacy of laparoscopic Nissen fundoplication in eliminating reflux has been documented. This study was undertaken to determine changes in quality of life and cost of antireflux medications after laparoscopic Nissen fundoplication. One hundred patients undergoing laparoscopic Nissen fundoplication between 1992 and 1997 completed questionnaires assessing changes in pre- and postoperative cost and number of antireflux medications, reflux symptoms, and quality of life. The average number of antireflux medications was significantly reduced (1.8 versus 0.3, P < 0.0001) as was the average monthly cost ($170 versus $30, P < 0.0001). Patients reported significant (P < 0.05) symptomatic improvement in postprandial heartburn, nocturnal heartburn, postprandial nausea, postprandial vomiting, dysphagia, and gas/bloating. Patients in this series noted fewer symptoms and used fewer antireflux medications at less cost after laparoscopic Nissen fundoplication. Symptoms commonly thought of as complications of fundoplication (vomiting, dysphagia, gas/bloating) were less common after fundoplication. This report documents the efficacy of laparoscopic fundoplication in improving quality of life and reducing use and cost of antireflux medications.

[How expensive is treatment of reflux disease?]

In a prospective documented series of reflux patients, a retroelective analysis of medication cost and duration of conservative therapy as well as the costs for surgical therapy including preoperative diagnostic workup, cost during hospitalization, and costs for complications with necessary additional treatment and readmissions is assessed. Cost-relevant factors are in conservative treatment cost-relevant factors are those patients who need increasing dosages, while in surgical treatment the cost-relevant patients are those with complications who need additional treatment.

Lifetime costs of surgical versus medical treatment of severe gastro-oesophageal reflux disease in Finland

BACKGROUND

Gastro-oesophageal reflux disease (GERD) can be effectively treated pharmacologically or surgically. As GERD is often a chronic condition, we compared the long-term costs of medical and surgical management.

METHODS

The medical regimens were ranitidine (150 or 300 mg/day), omeprazole (20 or 40 mg/day), and lansoprazole (30 mg/day), with costs calculated for total life expectancy after diagnosis and for one-third of that time. Costs for open or laparoscopic surgery (Nissen fundoplication) included pre- and post-operative investigations, sick leave, and calculated financial loss due to fatal outcome.

RESULTS

Costs were lowest with ranitidine, 150 mg/day, for one-third of the patient's lifetime and highest with lifelong omeprazole, 40 mg/daily. The cost of open or laparoscopic operation was less than that of lifelong daily treatment with proton pump inhibitors or ranitidine, 300 mg daily.

CONCLUSION

In Finland, antireflux surgery for GERD is cheaper than lifetime treatment with proton pump inhibitors.
