Gastroesophageal reflux, quality of life, and satisfaction in patients with achalasia treated with open cardiomyotomy and partial fundoplication

Laparoscopic calibrated total vs partial fundoplication following Heller myotomy for oesophageal achalasia

AIM: To compare the mid-term outcomes of laparoscopic calibrated Nissen-Rossetti fundoplication with Dor fundoplication performed after Heller myotomy for oesophageal achalasia.

METHODS: Fifty-six patients (26 men, 30 women; mean age 42.8 ± 14.7 years) presenting for minimally invasive surgery for oesophageal achalasia, were enrolled. All patients underwent laparoscopic Heller myotomy followed by a 180° anterior partial fundoplication in 30 cases (group 1) and calibrated Nissen-Rossetti fundoplication in 26 (group 2). Intraoperative endoscopy and manometry were used to calibrate the myotomy and fundoplication. A 6-mo follow-up period with symptomatic evaluation and barium swallow was undertaken. One and two years after surgery, the patients underwent symptom questionnaires, endoscopy, oesophageal manometry and 24 h oesophago-gastric pH monitoring.

RESULTS: At the 2-year follow-up, no significant difference in the median symptom score was observed between the 2 groups (P = 0.66; Mann-Whitney U-test). The median percentage time with oesophageal pH < 4 was significantly higher in the Dor group compared to the Nissen-Rossetti group (2; range 0.8-10 vs 0.35; range 0-2) (P < 0.0001; Mann-Whitney U-test).

CONCLUSION: Laparoscopic Dor and calibrated Nissen-Rossetti fundoplication achieved similar results in the resolution of dysphagia. Nissen-Rossetti fundoplication seems to be more effective in suppressing oesophageal acid exposure.

Balloon dilatation of esophageal strictures/achalasia

Achalasia is an esophageal motor disorder characterized by increased lower esophageal sphincter (LES) pressure, diminished-to-absent peristalsis in the distal portion of the esophagus composed of smooth muscle, and lack of a coordinated LES relaxation in response to swallowing. These abnormalities are recognized radiographically by aperistalsis, esophageal dilatation, and decreased opening of the LES, with a characteristic "bird-beak" appearance. The principal symptom of this disorder is dysphagia and pneumatic dilatation is designed to alleviate or cure this symptom.

Disease-specific health-related quality of life in patients with esophageal achalasia before and after therapy

BACKGROUND

To evaluate disease-specific health-related quality of life (HRQoL) in patients with symptomatic esophageal achalasia before and after therapy.

METHODS

Symptoms and disease-specific HRQoL were evaluated before and 3 months after therapy. Therapy selection, either dilatation or myotomy, depended exclusively on the opinion of the physician on charge of the patient. Symptom severity was graded from 0 to 3, using a scoring system. A disease-specific questionnaire for achalasia developed and validated in Spanish language with 18 items and four subscales (AE-18) was used to evaluate HRQoL. Changes after therapy in HRQoL and its association with clinical improvement were analyzed.

KEY RESULTS

Sixty-five patients were prospectively included in eight hospitals in Spain. Of them, 47 were treated with dilatation, and 18 with laparoscopic Heller myotomy. After therapy, AE-18 global and subscales scores improved significantly. Changes in HRQoL were associated with improvement in symptoms. An important improvement in symptoms (>or=50%) was needed to obtain a minimal clinically important improvement (>or=20%) in HRQoL.

CONCLUSIONS & INFERENCES

Disease-specific HRQoL improves in patients with symptomatic achalasia after therapy with dilatation or myotomy. The degree of improvement of HRQoL depends on the degree of improvement of esophageal symptoms.

Significance of limited hiatal dissection in surgery for achalasia

INTRODUCTION

It is speculated that postoperative pathologic gastroesophageal reflux after Heller's myotomy can be diminished if the lateral and posterior phrenoesophageal attachments are left intact. The aim of this study was to evaluate the effectiveness of limited hiatal dissection in patients operated due to achalasia.

METHODS

Prospective, randomized, 3 years follow-up of 84 patients operated due to achalasia. In 26 patients, Heller-Dor with complete hiatal dissection was done (G1), limited hiatal dissection combined with myotomy and Dor's procedure was performed in 36 patients (G2), and with Heller's myotomy alone in 22 (G3). Stationary manometry and 24 h pH study were performed in regular postoperative intervals.

RESULTS

Postoperatively, higher median values of lower esophageal sphincter resting pressures were marked in G2 and G3, while patients in G1 were presented with higher median values of pH acid score (p < 0.001). Abnormal DeMeester score 3 years after surgery was present in 23.1% of patients in G1 and 8.5% and 9.1% in G2 and G3 accordingly. There was no statistical difference between the groups concerning postoperative dysphagia recurrence.

CONCLUSION

Indicating further long-term studies, 3 years after the operation limited hiatal dissection compared to complete obtains better reflux control in achalasia patients, regardless of Dor's fundoplication.

Treatment for Barrett's oesophagus

BACKGROUND

Treatments for Barrett's oesophagus, the precursor lesion of adenocarcinoma, are available but whether these therapies effectively prevent the development of adenocarcinoma, and in some cases eradicate the Barrett's oesophagus segment, remains unclear.

OBJECTIVES

To summarise, quantify and compare the efficacy of pharmacological, surgical and endoscopic treatments for the eradication of dysplastic and non-dysplastic Barrett's oesophagus and prevention of these states from progression to adenocarcinoma.

SEARCH STRATEGY

We searched CENTRAL (The Cochrane Library 2004, issue 4), MEDLINE (1966 to June 2008) and EMBASE (1980 to June 2008).

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing medical, endoscopic or non-resectional surgical treatments for Barrett's oesophagus. The primary outcome measures were complete eradication of Barrett's and dysplasia at 12 months, and reduction in the number of patients progressing to cancer at five years or latest time point.

DATA COLLECTION AND ANALYSIS

Three authors independently extracted data and assessed the quality of the trials included in the analysis.

MAIN RESULTS

Sixteen studies, including 1074 patients, were included. The mean number of participants in the studies was small (n = 49; range 8 to 208). Most studies did not report on the primary outcomes. Medical and surgical interventions to reduce symptoms and sequelae of gastro-oesophageal reflux disease (GORD) did not induce significant eradication of Barrett's oesophagus or dysplasia. Endoscopic therapies (photodynamic therapy (PDT with aminolevulinic acid or porfimer sodium), argon plasma coagulation (APC) and radiofrequency ablation (RFA)) all induced regression of Barrett's oesophagus and dysplasia. The data for photodynamic therapy were heterogeneous with a mean eradication rate of 51% for Barrett's oesophagus and between 56% and 100% for dysplasia, depending on the treatment regimens. The variation in photodynamic therapy eradication rates for dysplasia was dependent on the drug, source and dose of light. Radiofrequency ablation resulted in eradication rates of 82% and 94% for Barrett's oesophagus and dysplasia respectively, compared to a sham treatment. Endoscopic treatments were generally well tolerated, however all were associated with some buried glands, particularly following argon plasma coagulation and photodynamic therapy, as well as photosensitivity and strictures induced by porfimer sodium based photodynamic therapy in particular.

AUTHORS' CONCLUSIONS

Despite their failure to eradicate Barrett's oesophagus, the role of medical and surgical interventions to reduce the troubling symptoms and sequelae of GORD is not questioned. Whether therapies for GORD reduce the cancer risk is not yet known. Ablative therapies have an increasing role in the management of dysplasia within Barrett's and current data would favour the use of radiofrequency ablation compared with photodynamic therapy. Radiofrequency ablation has been shown to yield significantly fewer complications than photodynamic therapy and is very efficacious at eradicating both dysplasia and Barrett's itself. However, long-term follow-up data are still needed before radiofrequency ablation can be used in routine clinical care without the need for very careful post-treatment surveillance. More clinical trial data and in particular randomised controlled trials are required to assess whether or not the cancer risk is reduced in routine clinical practice.

Achalasia: A review of Western and Iranian experiences

Achalasia is a primary motor disorder of the esophagus, in which esophageal emptying is impaired. Diagnosis of achalasia is based on clinical findings. The diagnosis is confirmed by radiographic, endoscopic, and manometric evaluations. Several treatments for achalasia have been introduced. We searched the PubMed Database for original articles and meta-analyses about achalasia to summarize the current knowledge regarding this disease, with particular focus on different procedures that are used for treatment of achalasia. We also report the Iranian experience of treatment of this disease, since it could be considered as a model for medium-resource countries. Myotomy, particularly laparoscopic myotomy with fundoplication, is the most effective treatment for achalasia. Compared to other treatments, however, the initial cost of myotomy is usually higher and the recovery period is longer. When performing myotomy is not indicated or not possible, graded pneumatic dilation with slow rate of balloon inflation seems to be an effective and safe initial alternative. Injection of botulinum toxin into the lower esophageal sphincter before pneumatic dilation may increase remission rates. However, this needs to be confirmed in further studies. Due to lack of adequate information regarding the role of expandable stents in the treatment of achalasia, insertion of stents does not currently seem to be a recommended treatment. In summary, laparoscopic myotomy can be considered as the procedure of choice for treatment of achalasia. Graded pneumatic dilation is an effective alternative when the performance of myotomy is not possible for any reason.

After laparoscopic Heller myotomy, do emergency department visits or readmissions predict poor long-term outcomes?

INTRODUCTION

Laparoscopic Heller myotomy is a first-line treatment for achalasia. To improve outcomes after myotomy and to determine if poor early results predict later outcomes, emergency department (ED) visits and readmissions within 60 days following laparoscopic Heller myotomy were studied.

MATERIALS AND METHODS

Since 1992, 352 patients have undergone laparoscopic Heller myotomy and are followed through a prospectively maintained registry. Causes of ED visits and readmissions within 60 days after myotomy were determined. Patients scored their symptoms of achalasia before myotomy and at last follow-up; scores were compared to determine if the reasons leading to ED visits and/or readmissions impacted long-term outcome after myotomy.

RESULTS

Fourteen (4%) patients had ED visits, and 18 (5%) patients had readmissions within 60 days following myotomy. Sixty-four percent of ED visits were for dysphagia/vomiting and 36% were for abdominal/chest pain, while 37% of readmissions were for dysphagia/vomiting. Pneumonia was complicated by empyema in four patients, all without leaks; two patients expired. Despite ED visits/readmissions, achalasia symptom (e.g., dysphagia, regurgitation, choking, heartburn, and chest pain) frequency and severity scores improved after myotomy (p < 0.05 for all).

CONCLUSIONS

ED visits and readmissions are infrequent following laparoscopic Heller myotomy. ED visits were generally due to complaints related to achalasia or edema after myotomy, while readmissions were generally related to complications of operative intervention or chronic ill health. Despite ED visits or readmissions early after myotomy, symptoms of achalasia are well palliated by myotomy long-term.

Patterns of esophageal acid exposure after laparoscopic Heller's myotomy and Dor's fundoplication for esophageal achalasia

BACKGROUND

Heller's myotomy for esophageal achalasia is associated with less esophageal acid gastroesophageal reflux when combined a Dor's fundoplication. The Aim of the study was to assess the incidence of postoperative esophageal acid exposure after laparoscopic Heller's myotomy and Dor's fundoplication (HM-DF).

METHODS

Seventy six patients (37 males) with esophageal achalasia were prospectively followed-up by clinical interview and laboratory tests before and after laparoscopic HM-DF. A symptom score was used for clinical assessment. Laboratory assessment included esophageal standard manometry, esophagogram and esophageal pH 24-hour monitoring before and 1- and 5-years after surgery.

RESULTS

Symptom score improved at 1-year after surgery (P < 0.001). Heartburn was only reported by 5 patients, dysphagia or/and regurgitation by 28 and substernal pain by 12. 91% of patients had satisfactory functional results. Pathological esophageal exposure to acid was seen in 21% of the cases. Pathological acid events showed the features of pseudoreflux in 66%t and those of true GER in 34%. Pathologically increased esophageal exposure to acid was more commonly detected in patients with a pseudodiverticulum (P = 0.001) and was related to the diameter of distal esophagus and symptom score (P < 0.001). There was no reduction in esophageal acid exposure after treatment with proton pump inhibitors in 16 patients. Neither the symptom score nor esophageal acid exposure at esophageal pH monitoring changed significantly at the 5-year follow-up in 35 patients. Esophageal configuration remained unchanged.

CONCLUSIONS

Increased esophageal exposure to acid after laparoscopic HM-DF for esophageal achalasia i) is detected in 21% of patients, and is rather the result of food stagnation than of true GER, ii) is more commonly seen in cases with pseudodiverticulum, iii) is related to the diameter of distal esophagus, iv) does not respond to antisecretory treatment and v) does not deteriorate by time.

Results of laparoscopic Heller myotomy without anti-reflux procedure in achalasia. Monocentric prospective study of 106 cases

BACKGROUND

Heller myotomy (HM) combined with an anti-reflux procedure has been shown to be effective for the treatment of achalasia, as postoperative gastro-esophageal reflux (GER) is observed in about 10% of the cases. Laparoscopy has brought an undeniable benefit in providing excellent visualisation of the gastro-esophageal junction (GEJ) without lateral and posterior dissection. Respecting the anatomical fixation of the GEJ seems to permit the performing of HM without an anti-reflux procedure, the need for which is therefore debatable. The purpose of this study was to analyse the results of this controversial procedure.

METHODS

A monocentric prospective study was carried out on 106 patients who underwent HM without an anti-reflux procedure. The postoperative assessment consisted of a manometry and a 24-hour pH study two months after surgery, and a yearly clinical examination for a minimum of five years. The data capture was done using a statistical analysis.

RESULTS

There was no mortality, one conversion to an open procedure, and four mucosal perforations. Postoperative morbidity was 2%. The average follow-up period was 55 months (range, 2 to 166), with 10 patients lost to follow-up. Good functional results were observed in 91.4% of patients at one year, and 78.6% at five years. Two months after surgery, a 9.4% prevalence of GER was detected in the pH study, and the lower esophageal sphincter pressure had significantly decreased. After a long term follow-up we observed an 11.3% global rate of GER. No repeat surgery was necessary to control postoperative GER.

CONCLUSIONS

Laparoscopic HM without anti-reflux procedure gives good functional results provided the anatomical fixation of the GOJ is respected.

Persisting symptoms and decreased health-related quality-of-life in a cross-sectional study of treated achalasia patients

BACKGROUND

Little is known about symptom characteristics of treated achalasia patients and their effect on health-related quality-of-life (HRQoL).

AIMS

To examine clinical remission, achalasia-associated symptoms and HRQoL in treated achalasia patients.

METHODS

The Eckardt clinical symptom score, RAND-36 and a disease-specific HRQoL questionnaire were sent to 171 treated achalasia patients.

RESULTS

76.6% of the patients returned their questionnaire. 44.9% of them were not in symptomatic remission. Prevalence of frequent dysphagia (at least daily) and chest pain (at least weekly) was 46% and 38%, respectively. Achalasia patients had lower general HRQoL scores than control subjects (all RAND-36 subscales, except health change; P < or = 0.002). Patients with frequent symptoms of chest pain and dysphagia showed lower HRQoL than patients with less frequent symptoms on three RAND-36 subscales (pain, social functioning and general health perceptions; P < 0.003). Patients in clinical remission showed higher HRQoL than patients who were not, however HRQoL in the 'remission group' remained significantly impaired as compared to controls (all RAND-36 subscales except emotional role limitations and mental health; P < 0.001).

CONCLUSIONS

Many achalasia patients remain severely symptomatic after treatment and have decreased HRQoL. Frequent symptoms are associated with lower HRQoL. Patients in clinical remission show substantially improved, but not restored HRQoL.

Relief of dysphagia after laparoscopic Heller myotomy improves long-term quality of life

BACKGROUND AND OBJECTIVE

Quality of life (QoL) is getting more attention in the medical literature. Treatment outcomes are now gauged by their effect on the QoL along with their direct effect on the diseases they are targeting. The aim of the study was to assess the impact of residual dysphagia on QoL after laparoscopic Heller myotomy for achalasia.

METHODS

QoL was evaluated using the short-form-36 (SF-36) and postoperative dysphagia was assessed using a dysphagia score. The score (range 0-10) was calculated by combining the frequency of dysphagia (0=never, 1 = < 1 day/wk, 2 = 1 day/wk, 3 = 2-3 days/wk, 4 = 4-6 days/wk, 5=daily) with the severity (0=none, 1=very mild, 2=mild, 3=moderate, 4=moderately severe, 5=severe). Patients were classified in the Nonresponder group when their dysphagia score was in the upper quartile.

RESULTS

Questionnaires were mailed to 110 patients. The overall response rate was 91% with 100 patients (54 female) returning the questionnaires. The average follow-up was 3.3 years. There was a significative inverse correlation between dysphagia score and mental component (P = 0.0001) and total SF-36 (P = 0.001) scores. According to their postoperative dysphagia scores, 77 patients were assigned to the Responder Group and 23 patients to the Nonresponder Group. The two groups were similar in terms of age, gender, rate of fundoplication, and length of follow-up. Mental component and total SF-36 scores were significantly (P < 0.05) higher in the Responder group. Successful relief of dysphagia after Heller myotomy was associated with health-related quality of life scores that were 13 higher in Vitality (P < 0.05), 11 points higher in mental health (P < 0.05), and 12 points higher in General Health (P < 0.05). Overall patient satisfaction with surgical outcome was 92%, with only eight patients not satisfied with the surgery.

CONCLUSION

Laparoscopic Heller myotomy offers excellent long-term relief of achalasia-related symptoms, namely dysphagia, and this was projected on a significant improvement in quality of life and patient satisfaction.

Management of achalasia with transabdominal esophagocardiomyotomy and partial posterior fundoplication

In this article we present our experience in the management of achalasia. From May 1988 through August 2005, 71 patients with achalasia underwent transabdominal esophagocardiomyotomy and partial posterior fundoplication. Barium swallow, manometry, and 24-h pH studies were performed in all patients preoperatively. Manometry and 24-h pH monitoring were only carried out in 58 patients at the third post-operative week and in 43 patients during follow-up, even though 52 patients were included in the follow-up. There were no operative deaths or complications. All the 71 patients were able to eat semifluid or solid food without dysphagia and heartburn at discharge. Esophageal barium studies showed that the maximum esophageal diameter decreased 2.2 cm and the minimum gastroesophageal junction diameter increased 8.4 mm after operation. Manometry examination in 58 patients revealed that the lower esophageal sphincter resting pressure decreased 15.0 mmHg in the wake of the procedure. Twenty-four hour pH monitoring demonstrated that reflux events were within the normal post-operative range. Fifty-five of the 58 patients had normal DeMeester scores. Among the patients with a mean 90-month follow-up, 49 patients had normal intake of food without reflux, the remaining three had mild dysphagia without requiring treatment. All the patients resumed their preoperative work and social activities. The manometry and 24-h pH studies in the 43 patients showed there were no significant changes between the third post-operative week and during follow-up. Transabdominal esophagocardiomyotomy and posterior partial fundoplication are able to relieve the functional outflow obstruction of the lower esophageal sphincter, obviate the rehealing of the myotomy edge and prevent gastroesophageal reflux in patients who have undergone myotomy alone.

Long-term results of laparoscopic Heller myotomy with partial fundoplication for the treatment of achalasia

BACKGROUND

Treatment options for achalasia include medications, endoscopic balloon dilation, injection of botulinum toxin, or surgery.

METHODS

The clinical course of 75 consecutive patients who underwent minimally invasive Heller myotomy and partial fundoplication for achalasia between 1991 and 2001 was reviewed by means of a questionnaire.

RESULTS

Mean follow-up was 5.3 (range .8 to 10.9) years. Sixty-four percent of questionnaires were returned. Thirty-seven patients (84%) felt much better and 6 (14%) slightly better; 1 (2%) rated the result as unchanged. Twenty-six patients (59%) experienced weight gain. Seven patients (16%) had persistent swallowing problems and 5 (11%) reported frequent reflux. Twenty-five percent underwent additional therapy, including dilation (n = 8, 18%), repeat surgery (n = 2, 5%), and botulinum toxin injection (n = 2, 5%). Eighteen patients (41%) were using a proton pump inhibitor or H2 blocker, three were on a calcium channel blocker (7%), and 1 was using nitroglycerine (2%).

CONCLUSION

Laparoscopic Heller myotomy can achieve short- and long-term results comparable to open surgery and should be considered the treatment of choice for patients suffering from achalasia. Despite the frequent need for further therapy, patient satisfaction is good.

Relationship between subjective and objective outcome measures after Heller myotomy and Dor fundoplication for achalasia

BACKGROUND

The purpose of this study is to assess how subjective evaluation (heartburn, dysphagia, quality of life, and satisfaction) correlates with objective data after Heller myotomy and Dor fundoplication for achalasia.

METHODS

A total of 53 consecutive patients with achalasia undergoing laparoscopic Heller myotomy and Dor fundoplication were studied prospectively. Subjective evaluation was done preop and postop using the Gastroesophageal Reflux Disease Health-Related Quality of Life instrument (GERD-HRQL; 0 = best, 45 = worse), 4-point dysphagia and heartburn scales (0 = best, 3 = worst), patient satisfaction scale (0 = very satisfied, 5 = incapacitated), and the SF-12 general health-related quality-of-life score. At 3 months postop, patients were asked to undergo objective evaluation with 24-h pH testing, manometry, and endoscopy. Data are expressed as median (interquartile range) and analyzed by Wilcoxon signed rank test or Mann-Whitney U test.

RESULTS

Forty-nine patients were more than 3 months postsurgery. Comparing preop to postop, improvements were found in dysphagia [3 (2-3) to 0 (0-1)], heartburn [1 (0-2) to 0 (0-1)], GERD-HRQL [13.5 (6.3-22.5) to 2 (0-5)], satisfaction [3 (3-4) to 1 (0-1)], and SF-12 mental component summary [46 (37-56) to 58 (50-59)] and physical component summary [46 (36-53) to 55 (48-56)] scores (p < 0.0001 for all). Thirty-eight patients (78%) agreed to undergo objective testing, and complete data were available for 32 (65%). Four of 32 patients (12.5%) had evidence of reflux based on 24-h pH testing. Of nine patients with GERD-HRQL >5, only two had positive pH test (22%). Of 23 patients with GERD-HRQL <5, two had positive pH test (7%). Of four tested patients with moderate to severe heartburn, two had an abnormal pH test. There was no significant relationship between GERD-HRQL score and pH test results. Lower esophageal sphincter pressure (LESP) decreased from 24 (16-35) to 13 mmHg (11-17) (p < 0.001). There was no relationship between dysphagia score and postop absolute LESP or a decrease in LESP after operation.

CONCLUSIONS

Laparoscopic Heller myotomy and Dor fundoplication is an effective treatment for achalasia. Subjective evaluation can document patient satisfaction and health-related quality of life but does not accurately reflect postop reflux. Twenty-four-hour pH study is required to accurately assess reflux disease.

Laparoscopic Heller myotomy provides durable relief from achalasia and salvages failures after botox or dilation

OBJECTIVE

To report outcome after laparoscopic Heller myotomy in a large number of patients.

SUMMARY BACKGROUND DATA

Laparoscopic Heller myotomy has been undertaken for over a decade, but most studies involve small numbers of patients with limited follow-up.

METHODS

Since 1992, 262 patients have undergone laparoscopic Heller myotomy and been prospectively followed. Concomitant fundoplication was undertaken for a patulous hiatus or large hiatal hernia or to buttress the repair of an esophagotomy until recently when it became routinely applied. With mean follow-up at 32 months, symptoms were scored by patients on a Likert scale (frequency: 0 = Never to 10 = Every time I eat/always; severity: 0 = Not bothersome to 10 = Very bothersome).

RESULTS

Before myotomy, 79% received Botox or bag dilation: 52% had Botox, 59% underwent dilation, and 36% had both. Inadvertent esophagotomy occurred in 5%. Concomitant diverticulectomy was undertaken in 4%, and fundoplication was undertaken in 30%. Complications were infrequent. Median length of stay was 1 day. After myotomy, the frequency and severity of symptoms of achalasia and reflux significantly decreased. Eighty-eight percent of patients felt their symptoms were greatly improved or resolved, and 90% felt their outcome was satisfying or better. Ninety-three percent felt they would undergo myotomy again, if necessary.

CONCLUSIONS

Laparoscopic Heller myotomy can safely and durably relieve symptoms of dysphagia while also reducing symptoms of reflux. Length of stay is short and patient satisfaction is very high with extended follow-up. Laparoscopic Heller myotomy is strongly encouraged for patients with symptomatic achalasia and is efficacious even after failures of dilation and/or Botox therapy.

A total fundoplication is not an obstacle to esophageal emptying after heller myotomy for achalasia: results of a long-term follow up

OBJECTIVE

The aim of this study was to evaluate the role and efficacy of a total 360 degrees wrap, Nissen-Rossetti fundoplication, after esophagogastromyotomy in the treatment of esophageal achalasia.

SUMMARY BACKGROUND DATA

Surgery actually achieves the best results in the treatment of esophageal achalasia; the options vary from a short extramucosal esophagomyotomy to an extended esophagogastromyotomy with an associated partial fundoplication to restore the main antireflux barrier. A total 360 degrees fundoplication is generally regarded as an obstacle to esophageal emptying.

MATERIALS AND METHODS

Since 1992 to November 2003, a total of 195 patients (91 males, 104 females), mean age 45.2 years (range, 12-79 years), underwent laparoscopic treatment of esophageal achalasia. Intervention consisted of Heller myotomy and Nissen-Rossetti fundoplication with intraoperative endoscopy and manometry.

RESULTS

In 3 patients (1.5%), a conversion to laparotomy was necessary. Mean operative time was 75 +/- 15 minutes. No mortality was observed. Overall major morbidity rate was 2.1%. Mean postoperative hospital stay was 3.6 +/- 1.1 days (range, 1-12 days). At a mean clinical follow up of 83.2 +/- 7 months (range, 3-141 months) on 182 patients (93.3%), an excellent or good outcome was observed in 167 patients (91.8%) (dysphagia DeMeester score 0-1). No improvement of dysphagia was observed in 4 patients (2.2%). Gastroesophageal pathologic reflux was absent in all the patients.

CONCLUSIONS

Laparoscopic Nissen-Rossetti fundoplication after Heller myotomy is a safe and effective treatment of esophageal achalasia with excellent results in terms of dysphagia resolution, providing total protection from the onset of gastroesophageal reflux.

Age Affects Presenting Symptoms of Achalasia and Outcomes after Myotomy

Older patients with achalasia presumably have had a longer, more indolent course than younger patients. This study was undertaken to determine the impact of patient age and duration of symptoms on symptom severity and outcome after Heller myotomy. Two hundred sixty-two patients (142 men and 120 women), of average age 49 years ± 17.7 (SD), have undergone laparoscopic Heller myotomy. Patients scored their symptoms using a Likert scale and subjectively rated their overall outcome. Data are presented as median, mean ± SD, when appropriate. Follow-up is 25 months, 32 months ± 28.7. Symptom severity scores improved after myotomy ( P < 0.001 for all, paired Student's t test). Before myotomy, older patients had less dysphagia, regurgitation, choking, and chest pain ( P < 0.05). Duration of preoperative symptoms did not correlate with frequency of symptoms. After myotomy, older patients had lower scores for dysphagia, chest pain, choking, and heartburn ( P < 0.01); patients with prolonged durations of symptoms had lower dysphagia and choking scores. Neither age nor duration of symptoms had a significant effect on overall subjective outcomes. All patients should expect significant reductions in symptoms of achalasia following myotomy. Age and duration of symptoms impact symptoms before and after myotomy, but neither seem to impact subjective measure of outcome.

Long-term outcome of Heller myotomy in achalasic sigmoid esophagus

OBJECTIVE

We sought to assess the long-term outcome of Heller myotomy and anterior fundoplication in patients with achalasic sigmoid esophagus.

METHODS

Fourteen patients with achalasia and sigmoid esophagus (median age, 42.5 years) operated on by the same surgeon through a laparotomy (n = 8) or laparoscopic approach (n = 6) between 1985 and 2000 were evaluated. According to a 4-grade classification (1, no symptoms; 4, persistent symptoms), both dysphagia and regurgitation had a median score of 4.0. Five patients complained of respiratory symptoms. Six patients had undergone previous pneumatic dilation. Preoperative and postoperative workup included an esophagogram, esophagoscopy, manometry, and health-related quality-of-life assessment with the Short-Form 36-item questionnaire.

RESULTS

Median follow-up was 85 months. At 24 months, esophageal width decreased by 10 mm (P =.003), and the change correlated inversely with the age of the patients (R = -0.61; P =.02). Lower esophageal sphincter pressure decreased by 17 mm Hg (P =.001), and both dysphagia and regurgitation scores decreased to 1.0 (P <.003). Comparison with the results of 37 patients with earlier-stage achalasia showed no difference in changes of esophageal width, lower esophageal sphincter pressure, dysphagia score, and regurgitation score. Quality-of-life Short-Form 36-item questionnaire domains, including general health, social functioning, and vitality, improved significantly. Overall results were classified as excellent or good in 10 patients and as satisfactory and unsatisfactory in 2 patients each. No patient required esophagectomy or had esophageal carcinoma.

CONCLUSIONS

In this study Heller myotomy proved effective in improving subjective, objective, and quality-of-life outcome measures in patients with achalasic sigmoid esophagus and should be considered as the first-choice treatment for this severe condition.

Laparoscopic esophagomyotomy for achalasia: does anterior hemifundoplication affect clinical outcome?

OBJECTIVE

To determine whether the addition of anterior hemifundoplication to laparoscopic esophagomyotomy for achalasia yields better clinical outcomes than laparoscopic esophagomyotomy alone.

SUMMARY BACKGROUND DATA

Although hemifundoplication may prevent gastroesophageal reflux after esophagomyotomy for achalasia, it may also lead to persistent dysphagia in these patients with esophageal aperistalsis.

METHODS

This is a retrospective study of 51 consecutive patients (mean age 47.5 +/- 12.6 years) who had laparoscopic esophagomyotomy for achalasia by our group between August 1995 and January 2001. In 29 patients (57%) an anterior hemifundoplication was added to the esophagomyotomy. In 22 patients (43%), no wrap was added. Patients scored (0 = none; 1 = mild; 2 = moderate; 3 = severe) symptom severity (dysphagia, regurgitation, heartburn, chest pain) preoperatively and postoperatively. Weight gain, use of gastrointestinal (GI) medication, tolerance to food, and patient satisfaction were also assessed.

RESULTS

Mean patient follow-up was 33 months, and there were no operative deaths. Four patients were converted to open operation (8%). The wrap and no wrap groups were similar in terms of esophageal dilation, preoperative symptom severity and duration (5.7 +/- 7.1 versus 6.1 +/- 7.0 years), and preoperative weight loss (18 +/- 15 versus 20 +/- 20 pounds). Both groups had similar improvement in symptom grade postoperatively and equivalent satisfaction rates (86%). Postoperative weight gain, GI medication use, and food intolerance was also similar. Postoperatively, patients in the wrap group did not have higher dysphagia scores or lower heartburn scores than the no wrap group.

CONCLUSION

The addition of anterior hemifundoplication to esophagomyotomy for achalasia does not improve or worsen clinical results.
