Improvement in quality of life measures after laparoscopic antireflux surgery

Short- and long-term outcome and health-related quality of life after severe peritonitis

The short-form survey 36 (SF-36) is a useful and qualified instrument for measurement of health-related quality of life (HRQL) in critically ill patients. In this study we determined hospital mortality, hospital discharge mortality, and HRQL of 136 patients with severe peritonitis admitted to our hospital between January 1996 and May 1999. Hospital mortality was 46% and hospital discharge mortality 10%. The HRQL-questionnaire was answered completely by 97% of the patients who where still alive during the study period. Age significantly reduced physical functions in these patients. Patients with cancer had significant impaired physical functions in the first year, followed by significant impairment in emotion. Generally, patients who survived peritonitis and had no malignancy had an acceptable outcome when compared to individuals from a large normal population. Health-related quality of life measurements in peritonitis patients justify the high efforts in the treatment of these patients, but they do not provide a useful tool in the outcome prediction for individual patients.

Endoluminal delivery of radiofrequency energy to the gastroesophageal junction in uncomplicated GERD: efficacy and potential mechanism of action

OBJECTIVES

The endoluminal delivery of radiofrequency energy to the gastroesophageal junction has been shown to decrease symptoms of gastroesophageal reflux disease in a multicenter study. In this single-center trial, we sought to further examine its efficacy and physiological effects in patients with uncomplicated gastroesophageal reflux disease.

METHODS

Patients with chronic heartburn requiring maintenance antisecretory therapy but without a hiatal hernia >2 cm, severe esophagitis, or complications of gastroesophageal reflux disease were prospectively studied. Radiofrequency energy was delivered to the gastroesophageal junction using a transorally delivered, flexible bougie-tipped catheter and a thermocouple-controlled generator, under sedation and analgesia. The primary outcome measure was effect on reflux symptoms, assessed at baseline and at 1, 3, and 6 months, after treatment. Other outcome measures included effects on antireflux medication use, quality of life, overall patient satisfaction, esophageal motility, esophageal acid exposure, esophageal wall thickness, appearance of the cardioesophageal flap valve, and vagal efferent function.

RESULTS

A total of 18 patients underwent successful outpatient treatment without a serious adverse event. A significant improvement in symptom scores (Gastroesophageal Reflux Disease [GERD] Activity Index: 112.5 [range 76.2-140.6] vs 81.0 (74.2-97.6); p < 0.0001) and antacid use (17/wk [range 0-81] vs 0 (0-10); p < 0.0001) was noted at 6-month follow-up. No adverse effect on abdominal vagal function was identified and no significant change in any esophageal motility parameter was seen; however, a trend was noted toward a reduction in the number of transient lower esophageal sphincter relaxations induced by gastric air distension (3.5/h vs 1.0/h, p = 0.13). No detrimental effects on peristalsis or swallow-induced lower esophageal sphincter relaxation pressure were seen. Nonsignificant trends (p = 0.06) were noted regarding a decrease in the Hill score and an increase in esophageal wall thickness after treatment. Finally, although a decrease in all pH parameters in both the upper and lower esophagus was seen, none reached statistical significance.

CONCLUSIONS

Radiofrequency energy delivery to the region of the gastroesophageal junction provides effective symptom relief over the short term in patients with uncomplicated gastroesophageal reflux disease. It may achieve its therapeutic effect by reducing the frequency of transient lower esophageal sphincter relaxations triggered by gastric distension.

Dysphagia and quality of life after laparoscopic Nissen fundoplication in patients with and without prosthetic reinforcement of the hiatal crura

BACKGROUND

Recurrent hiatal hernia with or without intrathoracic wrap migration ("slipping Nissen") is one of the most common complications after laparoscopic Nissen fundoplication (LNF). Therefore, we decided to reinforce the hiatal crura using a prosthetic mesh prosthesis in an attempt to reduce recurrent hiatal hernia.

METHODS

The current nonrandomized study compares the surgical outcome, including quality of life data [Gastrointestinal Quality of Life Index (GIQLI)] and subjective degree of dysphagia, in a total of 200 patients with (n = 100) or without (n = 100) mesh prosthesis for a follow-up for at least 1 year.

RESULTS

There are no significant differences between groups in postoperative DeMeester score or lower esophageal sphincter pressure. In the group without mesh prosthesis, in 6 cases laparoscopic redo surgery was necessary due to severe and persistent dysphagia (n = 2) or a slipping Nissen (n = 4). Additionally, in 5 patients we found recurrent hiatal hernia, but patients have been without symptoms for at least 1 year. In the group with mesh prosthesis, laparoscopic refund application was performed in only 1 patient due to a slipping Nissen. In this group, recurrent hiatal hernia was not found in endoscopy. After laparoscopic antireflux surgery, GIQLI showed an equal improvement in both groups with an outcome comparable to that for healthy individuals. Postoperative dysphagia was significantly higher in the group with mesh prothesis within the 3 first months after surgery. One year after surgery no differences could be found.

CONCLUSIONS

Our findings suggest that LNF with reinforcement of the hiatal crura reduces the risk of recurrent hiatal hernia with or without wrap migration. In addition, LNF with mesh prosthesis improves patient's quality of life significantly to the same level as that in patients without mesh prosthesis. Postoperative dysphagia is higher in the early period after surgery, but this is only temporary. Long-term results of a randomized trial must be obtained before a general standardization can be discussed.

Health-related quality of life and gastrointestinal disease

Society is changing rapidly, and new aspects need to be considered when evaluating treatment of disease. Health-related quality of life (HRQL) is a relatively new addition to the tools clinicians use to gain a better understanding of the impact of disease and its treatment. The questions 'What is it?', 'How it is measured?' and 'How can the information be used?' are now better understood than a few years ago. Generic instruments to capture HRQL enable a broad assessment of a range of aspects and can be used to make comparisons between different patient populations. Irrespective of the choice of instrument, they can classify the influence of different factors, such as gender, age, general health status and disease severity. Health-related quality of life assessments have been made in many areas of gastroenterology, such as reflux disease, inflammatory bowel disease and irritable bowel syndrome, to describe the burden of illness and the impact of treatment. Health-related quality of life as a prediction of treatment response is another interesting option. Its ability in the context of surgical intervention and outcomes is also emerging even though more work must be done in this area. Health-related quality of life evaluations, as an additional tool in the management of patients, are here to stay.

Absence of gastroesophageal reflux disease in a majority of patients taking acid suppression medications after Nissen fundoplication

Recent studies have shown that many patients use acid suppression medications after antireflux surgery. The aim of this study was to determine the frequency of gastroesophageal reflux disease in a cohort of surgically treated patients with postoperative symptoms and a high prevalence of acid suppression medication use. The study group consisted of 86 patients who had symptoms following Nissen fundoplication that were sufficient to merit evaluation with 24-hour distal esophageal pH monitoring. All completed a detailed symptom questionnaire. The mean postoperative follow-up period was 28 months (median 18 months). Thirty-seven patients (43%) were taking acid suppression medications after fundoplication. Only 23% (20 of 86) of all the patients and only 24% (9 of 37) of those taking acid suppression medications had abnormal esophageal acid exposure on the 24-hour pH study. Heartburn and regurgitation were the only symptoms that were significantly associated with an abnormal pH study. Endoscopic assessment of the fundoplication was the most significant factor associated with an abnormal pH study. Multivariable logistic regression analysis showed that patients with a disrupted, abnormally positioned fundoplication had a 52.6 times increased risk of abnormal esophageal acid exposure. Most patients who use acid suppression medications after antireflux surgery do not have abnormal esophageal acid exposure, and the use of these medications is thus often inappropriate. Because of the limited predictive power of symptoms, objective evidence of reflux disease should be obtained before prescribing acid suppression medication for patients who have undergone antireflux surgery.

Quality of life after antireflux surgery compared with nonoperative management for severe gastroesophageal reflux disease

BACKGROUND

Gastroesophageal reflux disease significantly affects a patient's quality of life (QOL). Laparoscopic fundoplication offers an alternative to medical therapy, but few studies have compared outcomes. Our objective was to examine QOL scores in gastroesophageal reflux disease patients treated medically and surgically.

STUDY DESIGN

We undertook a retrospective analysis of patients undergoing surgical or medical treatment for gastroesophageal reflux disease over a 1-year period (August 1997 to August 1998). Followup QOL was measured using the Short-Form 36, and heartburn severity was measured using the Health Related Quality of Life scale (a disease-specific instrument with a best score of 0 and a worst score of 45).

RESULTS

Laparoscopic fundoplication was undertaken in 120 patients with a median age of 47 years (range 17 to 80 years). The medical cohort included 51 patients selected from the gastroenterology clinic with a median age of 48 years (range 17 to 82 years). Duration of heartburn was not significantly different, with 40 (78.4%) of the 51 medical and 98 (81.7%) of the 120 surgical patients having had symptoms for longer than 12 months. There were no operative deaths. There were 12 complications (esophageal perforation 1, pneumothorax 2, pneumonia 1, pulmonary embolus 3, other/miscellaneous 5). Mean length of stay was 1.6 days, time to oral intake 1.2 days, and return to normal activity 4.2 weeks. Routine followup was available in 118 surgical and 47 medical patients. The medical cohort had increased (p < 0.05) symptoms of heartburn (43% versus 19%), waterbrash (26% versus 8%), and regurgitation (30% versus 8%) and greater requirement for proton pump inhibitors (74% versus 19%) and propulsid (19% versus 3%) over the surgical group. Detailed outcomes were available in 101 surgical and 37 medical patients. Mean (+/-SE) Health Related Quality of Life scores were better (p < 0.05) in the surgical group (4+/-0.6 versus 21+/-1.4). More of the medical patients were dissatisfied (21.6% versus 5.9%). Short-Form 36 scores at followup were better (p < 0.05) in six of eight domains for surgical patients.

CONCLUSION

Heartburn scores and global QOL scores were superior after laparoscopic fundoplication compared with medical management in this patient population. Laparoscopic fundoplication should be considered for patients who are dissatisfied with medical treatment.

Using quality of life scores to help determine treatment: is restoring bowel continuity better than an ostomy?

OBJECTIVE: In colorectal surgery, evaluation of heath-related quality of life (HRQL) has been relatively minimal when compared to other medical specialties. Would the performance of such HRQL evaluations change our decision-making in patient care? In familial adenomatous polyposis (FAP), procedures that restore bowel continuity (i.e. Ileorectal anastomosis or ileal pouch anal anastomosis) are routinely preferred to ileostomy because of the perceived, but unproven, better HRQL. This study evaluates FAP patients who underwent prophylactic colectomy with either permanent ileostomy or 'restored bowel continuity' reconstruction. The functional outcomes of both groups are reported, and the HRQL assessments are compared. METHODS: All FAP patients who underwent (procto) colectomy resection with reconstruction, either restored bowel continuity (BC) or permanent ileostomy (OST), between 1980 and 1998 were studied. Functional data were obtained by questionnaire and medical record review. HRQL was assessed by 2 validated instruments - the SF-36 Physical and Mental Health Summary Scales and the SF-36 Health Survey - which measure physical summary (PSF) and mental summary functioning (MSF) as well as eight separate health quality dimensions including health perception (HP), physical (PF) and social functioning (SF), physical (PR) and emotional role limitations (ER), mental health (MH), bodily pain (BP), and energy level (E). RESULTS: Results were obtained in 54 patients; bowel continuity (44), ileostomy (10). Mean patient age was 39 years, mean follow up time was 10.5 years. Mean patient age at operation was 28 years. Functional results for BC included number of bowel movements/day (6.7), leakage (30%), having to wear a pad (11%), perianal skin problems (25%), food avoidance (68%), and inability to distinguish gas (27%). Functional results for OST were routinely excellent. Results of the HRQL surveys reveal no significant differences for BC vs OST (HP: 67 +/- 28 vs 79 +/- 39; PF: 91 +/- 14 vs 90 +/- 17; SF: 86 +/- 23 vs 97 +/- 5; PR: 79 +/- 34 vs 83 +/- 40; ER: 86 +/- 28 vs 88 +/- 27; MH: 77 +/- 19 vs 82 +/- 14; BP: 78 +/- 24 vs 71 +/- 32; E 60 +/- 21 vs 58 +/- 18, respectively). CONCLUSION: Although the perceived quality of life for ileostomy patients is generally worse than the 'restored bowel continuity' group, the measured HRQL is the same for both groups. These results suggest that a permanent ileostomy should be included as a viable and appropriate first line treatment option for FAP patients after resection. This study also suggests that HRQL should play a greater role in the evaluation of care and treatment in colorectal surgery.

Day Case Varicose Vein Surgery: Patient Health Outcome

Background:

The success of day case varicose vein surgery (DCWS) is traditionally denned clinically. However, the patient's perception of his or her own health prior to and following DCWS has not been established. This study prospectively measured the health status of patients with varicose veins, compared this with established population norms and assessed the impact of DCWS on both general health perception and varicose vein symptoms.

Method:

Fifty-three consecutive patients undergoing DCWS over a 9 month period were enrolled in this study. The SF-36 health assessment questionnaire and a vein-symptom-specific questionnaire were administered on the morning of surgery, 7 weeks postoperatively and 1 year following surgery. All patients in this study underwent a standard varicose vein operation and followed a standard protocol of postoperative management.

Results:

DCWS population health scores were lower than general population norms preoperatively. There was a significant improvement in the 7 week postoperative group in physical function and health perception (p<0.05). One year after surgery physical function, health perception, mental health and physical role were significantly improved from preoperative scores (p<0.05). Symptom-specific scores demonstrated a sustained trend towards improvement over the postoperative year.

Conclusion:

Varicose veins are associated with diminished well-being. Day case varicose vein surgery improves patient health perception and symptoms and is the treatment of choice for suitable patients with varicose veins.

Quality of life 2 years after laparoscopic total fundoplication: a prospective study

This study was a prospective evaluation of the quality of life of 50 patients after laparoscopic total fundoplication surgery for gastroesophageal reflux disease. The quality of life of 50 consecutive patients who underwent laparoscopic total fundoplication was evaluated using the Gastrointestinal Quality of Life Index questionnaire, which included 36 items in five different areas: symptoms, physical well-being, psychologic well-being, social relationships, and effects of medical treatment. Twenty-seven men and 23 women with a mean age of 52.6 +/- 16 years (range, 31-68 years) with gastroesophageal reflux disease were treated by laparoscopic total fundoplication (Nissen-Rosetti) and were included in the study. The follow-up was at least 2 years after surgery. The quality of life was evaluated before the surgery and 1 month, 3 months, 6 months, 1 year, and 2 years after surgery with follow-up in 100% of the cases. A control group of 50 healthy volunteers representing an identical population to that of the patients operated on (with respect to age, sex, body mass index, profession, and smoking) anonymously completed the same questionnaire. The preoperative and postoperative Gastrointestinal Quality of Life Index questionnaire scores of patients who had laparoscopic total fundoplication were compared with the Gastrointestinal Quality of Life Index questionnaire scores of the control group. Before surgery, the Gastrointestinal Quality of Life Index questionnaire score (86.7 +/- 8.5) was much inferior to that of the control group (123.8 +/- 13.6) (P < 0.001). This score significantly improved 3 months after surgery and was comparable (not significant) to that of the healthy control population 3 months, 6 months, 1 year, and 2 years after surgery (119.3 +/- 7.8). Improvements were reported mainly with respect to gastrointestinal symptoms and physical well-being. Social relationships were not modified. The quality of life of patients after laparoscopic surgery for gastroesophageal reflux disease improved and was close to the level expected in a healthy individual.

Laparoscopic fundoplication: a model for assessing new technology in surgical procedures

BACKGROUND

Surgical success has traditionally been judged from the surgeon's perspective. A more complete evaluation of outcome incorporates the patient's, surgeon's, and payor's perspectives. Because gastroesophageal reflux disease (GERD) is primarily a quality-of-life (QOL) problem, the evaluation of laparoscopic fundoplication (LF) is a useful model for evaluating outcomes from these 3 perspectives.

METHODS

Between 1995 and 2000, 74 patients underwent primary LF for GERD. In addition to undergoing physiologic testing, 63 patients (85%) were evaluated with use of a disease-specific health-related QOL scale (GERD-HRQL), scored from 0 (no symptoms) to 45 (incapacitating symptoms). Thirty-three patients also completed a generic QOL questionnaire (SF-12), in which patient satisfaction was scored from 1 (very satisfied) to 5 (very dissatisfied). Preoperative and postoperative data were compared with use of the Wilcoxon signed rank test or the paired t test.

RESULTS

The median GERD-HRQL score improved from 18 to 0 at 2 years postoperation (P <.01). The median satisfaction score improved from 5 to 1 (P <.01). The SF-12 summary scores also improved after 6 weeks postoperatively (P <.05). The mean +/- SD lower esophageal sphincter pressure rose from 7.3 +/- 4 mm Hg preoperatively to 17.5 +/- 6 postoperatively (P <.01), and the mean percentage of time that the esophagus was exposed to a pH of less than 4 declined from 14.7% +/- 12% to 1.1% +/- 2% (P <.01). The median operative time was 110 minutes, which declined with experience with the procedure (P <.01). Median postoperative stay was 2 days.

CONCLUSIONS

In evaluating the outcomes of a new procedure, 3 overlapping points of view were addressed: the patient's (QOL, satisfaction), the surgeon's (physiologic changes), and the payor's (operating room time, hospital stay). With use of this framework, we found that LF for GERD improves QOL, corrects the physiologic abnormalities, and is associated with short hospitalization and operating time that declines with experience with the procedure.

[Surgical treatment of gastroesophageal reflux disease in adults]

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

The quality of quality of life studies in general surgical journals

BACKGROUND

There has been a tremendous increase in interest on quality of life in surgical research. An increase in interest does not necessarily translate into better research. This study evaluates surgical articles that claim to measure or make some conclusion on quality of life.

STUDY DESIGN

All articles published in the calendar years 1996 and 1999 that purported to assess quality of life as end points or make some conclusion about quality of life were chosen for review from eight general surgical journals. Articles were assessed for use of a quality of life instrument, type of instrument, validation of the instrument, appropriateness of the instrument for the hypothesis, quality of statistical analysis, and adherence to the Gill and Feinstein criteria.

RESULTS

Of the 18 articles published in 1996, 72% used a quality of life instrument. Eighteen instruments were used in 13 studies: 7 generic, 10 disease-specific, and 1 ad hoc. Forty-three percent were validated, 39% were appropriate for the study hypothesis, 39% had correct statistical analysis. The majority did not meet the Gill and Feinstein criteria. Of the 24 studies published in 1999, 63% used a quality of life instrument. Twenty-two instruments were used in 15 studies: 11 generic, 5 disease-specific, and 6 ad hoc. Fifty-five percent were validated, 45% were appropriate, 45% had correct statistical analysis. Once again, the majority did not meet the Gill and Feinstein criteria.

CONCLUSIONS

Despite the emphasis on quality of life outcomes, a substantial number of studies made errors in conceptually defining quality of life and in use of quality of life instruments. Researchers and journal reviewers need to be better versed on the techniques of quality of life research.

[Quality of life one year after laparoscopic fundoplication is close to that of a control group: prospective study]

AIM OF THE STUDY

Prospective evaluation of the quality of life of patients after laparoscopic fundoplication for gastroesophageal reflux disease (GERD).

PATIENTS AND METHODS

The quality of life of 30 consecutive patients who underwent laparoscopic fundoplication was evaluated using the GIQLI (gastrointestinal quality of life index) questionnaire, which included 36 items in five different areas: digestive symptoms, physical condition, emotional reaction, social integration and medical treatment. Seventeen men and 13 women (mean age: 50.2 +/- 17 years (32-68) were included with a follow-up of at least 1 year and with complete data available. The quality of life was evaluated before surgery, and at 1 month, 3 months, 6 months and 1 year after surgery with a 100% follow-up. Thirty healthy volunteers representing an identical population (with respect to age, sex, BMI, profession, smoking, etc.) anonymously filled in the same questionnaire. The pre- and postoperative GIQLI scores of patients operated for GERD were compared with the GIQLI score of the control group.

RESULTS

Preoperatively, the GIQLI score (87 +/- 9.5) was much lower than that of the control group (123.4 +/- 13.6) (p < 0.001). This score significantly improved 3 months and 1 year after surgery and was comparable to that of the healthy population (115.3 +/- 9.6 vs 123.4 +/- 13.6 [ns]). Improvements were reported mainly with respect to digestive symptoms and physical condition. Social integration was slightly modified.

CONCLUSION

The quality of life of patients after laparoscopic antireflux surgery was greatly improved and was close to the level expected in an healthy population. However, the study demonstrated the possible presence of postoperative functional digestive disorders, although these symptoms were not considered as being uncomfortable, since the level of satisfaction was 96.6% (n = 29).

Quality of life before and after laparoscopic Heller myotomy for achalasia

BACKGROUND

Because the surgical treatment of achalasia is directed at the palliation of chronic symptoms, it is important to assess how surgery affects patients' health-related quality of life (HRQL).

METHODS

We evaluated upper gastrointestinal symptoms, satisfaction, and HRQL in 19 patients with achalasia before and after undergoing a laparoscopic Heller myotomy and partial fundoplication. HRQL was assessed using the Medical Outcomes Study 36-item short form health survey (SF-36).

RESULTS

The mean age of the patients was 40 years (range 16 to 74), and 58% were men. After a median follow-up of 21 months (range 2 to 35), 12 of 16 patients were satisfied with the results of their surgery. Liquid and solid dysphagia scores were improved after surgery, and the prevalence of heartburn symptoms did not change. Although all the health concepts measured by the SF-36 instrument showed some improvement, statistically significant increases (on a 0 to 100 scale) were detected in physical functioning (11.1, P = 0.02), role-physical (25.0, P = 0.05), bodily pain (12.2, P = 0.01), vitality (13.7, P = 0.02), and social functioning (18.4, P = 0.02).

CONCLUSIONS

Most aspects of HRQL improve after a laparoscopic Heller myotomy and partial fundoplication for achalasia.

Quality of life before and after laparoscopic Nissen fundoplication

BACKGROUND

Gastroesophageal reflux disease (GERD) is a common disorder in the Western world. The acute disease can usually be managed by medical therapy. To prevent relapse, many patients require lifelong medication. In these patients, laparoscopic antireflux surgery offers a good alternative. The aim of this study was to evaluate the postoperative results and compare pre- and postoperative quality of life after laparoscopic Nissen fundoplication.

METHODS

Clinical investigations, including esophageal manometry, pH monitoring, and endoscopy, and a previously validated Quality of Life Index, were performed before and a median of 41 month after antireflux surgery in 75 patients.

RESULTS

After laparoscopic Nissen fundoplication, the percentage of total time with pH <4 decreased from 10.4% to 3.2% on 24-h pH monitoring. The mean pressure of the lower esophageal sphincter improved from 8.1 to 12.3 mmHg. Esophagitis healed in 63 of 66 patients in whom it was present prior to surgery. The overall Quality of Life Index improved significantly from 86 +/- 16 to 116 +/- 16.

CONCLUSION

Laparoscopic fundoplication provides effective and durable relief of reflux in patients with GERD. The Quality of Life Index showed significant improvement after surgery.

Psychiatric disorders affect outcomes of antireflux operations for gastroesophageal reflux disease

BACKGROUND

Most of the information used to determine a patient's candidacy for antireflux surgery has centered on physiologic measurements of esophageal functioning and quantitative assessment of acid reflux. Unfortunately, little attention has been paid to the study of psychosocial factors that could affect outcomes. The purpose of this study was to establish whether concomitant psychiatric disorders might affect the symptomatic outcomes of antireflux surgery.

METHODS

We retrospectively reviewed a prospectively gathered database of patients with gastroesophageal reflux disease (GERD) who underwent either open or laparoscopic antireflux surgery. A history of a psychiatric disorder was considered to be present if the patient had been previously diagnosed with a DSM-IV psychiatric diagnosis and was being medically treated for it. Preoperatively, patients were evaluated with the symptom severity questionnaire, the GERD-HRQL (best score 0, worst score 50). Later in the series, patients were also evaluated with the generic quality-of-life questionnaire, the SF-36 (best score 100, worst score 0). After antireflux surgery, patients completed both questionnaires 6 weeks postoperatively.

RESULTS

A total of 94 patients underwent antireflux surgery. Seventy-seven of them had laparoscopic antireflux surgery (either Nissen or Toupet fundoplication), and 17 had open antireflux surgery (Nissen, Toupet, Collis-Nissen, or Belsey fundoplications). Nine patients had psychiatric disorders (five major depression, four anxiety disorders). At 6-week follow-up, 95.3% of patients without psychiatric disorders were satisfied with surgery, as compared to 11.1% of patients with psychiatric disorders (p < 0.000001). Patients satisfied with surgery had a median SF-36 mental health domain score of 76, as compared to a score of 36 for patients dissatisfied with surgery (p = 0.0002). Patients without psychiatric disorders showed improvement in the median total GERD-HRQL score from 27 preoperatively to 1 postoperatively (p < 0.000001), whereas patients with psychiatric disorders demonstrated less improvement, from 30 preoperatively to 10.5 postoperatively (p = 0.03).

CONCLUSIONS

Patients with psychiatric disorders are rarely satisfied with the results of antireflux surgery. Moreover, these patients demonstrated less symptomatic relief than patients without psychiatric disorders. Patients who were dissatisfied with antireflux surgery--even those without psychiatric disorders--had lower scores on the SF-36 mental health domain. These results suggest that even patients who might otherwise be candidates for antireflux surgery may have a poor symptomatic outcome, if they also have low mental health domain scores. Antireflux surgery in patients who suffer from major depression or anxiety disorder should be approached with great trepidation.

[Assessment of quality of life after antireflux surgery]

AIM OF THE STUDY

To assess the quality of life (QoL) of patients operated for gastroesophageal reflux disease (GERD).

PATIENTS AND METHODS

This prospective study included 82 consecutive patients submitted to antireflux surgery between October 1998 and January 1999. A new questionnaire was used to assess their QoL: the Gastrointestinal Quality of Life Index (GIQLI) that includes 36 items concerning 5 dimensions: symptoms, vitality, emotions, social relations and medical treatment. The series consisted of 44 men and 38 women with a mean age of 47 years (range: 18-78). QoL was assessed before and 6 months after surgery; the follow-up rate was 94% (77/82). The pre- and postoperative GIQLI scores of the study group and the GIQLY score of a control group of 110 healthy patients were compared.

RESULTS

Before surgery, the GIQLI score (90 +/- 23) was greatly impaired compared to the score (123 +/- 13) observed in the control group (p < 0.001). After surgery, the GIQLI score (110 +/- 23) increased significantly (p < 0.001), but remained statistically lower than the score of the control group (p < 0.001). The postoperative score recorded in the symptoms dimension was lower than the control group score: 55 +/- 11 versus 66 +/- 6 (p < 0.001), while no significant difference was observed in the other 4 dimensions. Univariate statistical analysis revealed that the postoperative GIQLI score (y) was correlated with the preoperative GIQLI score (x) according to the formula: y = 0.43 x + 71 (p < 0.001) and the sex of the patients, as the postoperative GIQLI score was higher in male patients (115 +/- 19) than in female patients (103 +/- 23) (p < 0.02).

CONCLUSION

The QoL of the patients was greatly improved after antireflux surgery, but remained lower than that of a control group of healthy subjects. Better patient selection should improve the results. In our series, male patients or patients with a high preoperative GIQLI score were the best candidates for antireflux surgery.

Laparoscopic esophageal surgery

In its 9-year history, laparoscopic esophageal surgery has become second only to gallbladder surgery in the frequency of minimally invasive procedures performed in routine surgical practice. Laparoscopic fundoplication has assumed a central role in the surgical treatment of gastroesophageal reflux. Laparoscopic myotomy has emerged as the optimal form of therapy for achalasia, and staging laparoscopy has been identified as an important adjunct to the preoperative evaluation of esophageal and gastroesophageal junction carcinoma. Laparoscopic paraesophageal hernia repair and remedial laparoscopic antireflux surgery currently are gaining acceptance. Laparoscopic gastroplasty, esophagectomy, and diverticulectomy are undergoing clinical trials, and their roles remain to be defined.

Quality of life before and after laparoscopic fundoplication

BACKGROUND

Laparoscopic fundoplication is a well-established surgical option for the treatment of gastroesophageal reflux disease. The aim of this study was to assess the surgical outcomes from the patient's point of view by using a validated quality of life instrument.

METHODS

Fifty patients have been prospectively included. All patients underwent a standardized 270-degree posterior fundoplication. Quality of life was measured by the Gastrointestinal Quality of Life Index (GIQLI), a 36-item-questionnaire. The patients received the questionnaire before surgery, and 3 months and 1 year after surgery.

RESULTS

Preoperative score was 95.6+/-21 points. The score increased significantly (P <0.0005) at 3 months (103.6+/-16) and 1 year (111.4+/-22) after surgery. This improvement concerned the four domains of the questionnaire (symptoms, social functioning, physical status, and emotions). The score in patients at 1 year remained, however, significantly lower than that in healthy persons (126+/-18).

CONCLUSIONS

GIQLI is a sensitive tool to assess surgical outcomes after fundoplication. The quality of life after surgery did not reach the level of healthy population, not because of failure of surgery to treat GERD but probably because of functional dyspepsia that was present prior to surgery and did not change after fundoplication.

Measuring improved quality of life after laparoscopic Nissen fundoplication

BACKGROUND

While the correction of pathologic gastroesophageal reflux by means of laparoscopic Nissen fundoplication (LNF) has been well documented, the psychological profiles of patients with this disease and the impact on their quality of life are less well understood. We obtained a baseline psychological profile and measured the impact of LNF on patients' quality of life with 2 standardized instruments: the psychological general well-being index (PGWB) and the gastrointestinal symptoms rating scale (GSRS). The study included 34 consecutive patients with typical symptoms of gastroesophageal reflux who underwent LNF in 1995 at a tertiary care university medical center.

METHODS

Patients filled out PGWB and GSRS surveys preoperatively and at 2 weeks, 2 months, and 12 months postoperatively. Data were collected in a blinded fashion by a study nurse and analyzed after completion of the study. Data are expressed as mean +/- standard deviation.

RESULTS

The mean preoperative PGWB score (69.6 +/- 17.3) of study patients with gastroesophageal reflux disease was lower than that expected for a healthy population. This was primarily attributable to low scores in the general health domain of the questionnaire, although LNF patients also had low scores in the vitality and positive well-being domains of the PGWB scale. LNF improved the PGWB score to a normal level (78.7 +/- 19.3) (P = .05 vs the preoperative PGWB score) at 12 months post surgery. The GSRS also showed improvement from 34.7 +/- 7.8 to 28.1 +/- 10 (P = .008). The improvement in GSRS was attributed to improvement in the heartburn (7.12 +/- 2.4 to 2.72 +/- 1.2, P < .001) and abdominal pain (6.58 +/- 2.5 to 4.92 +/- 1.6, P = .006) domains of the scale. LNF had no impact on the diarrhea, indigestion, and obstipation domains of the GSRS.

CONCLUSIONS

Patients with gastroesophageal reflux disease who are candidates for LNF have low psychological and general well-being scores that are restored to normal levels by successful LNF. When compared with baseline measurements, LNF effectively relieved heartburn and did not cause significant new gastrointestinal complaints.
