Predictors of improvement in health-related quality of life in patients undergoing cholecystectomy

BACKGROUND: Few studies have assessed health-related quality of life (HRQoL) among patients undergoing cholecystectomy. This study aimed to determine clinical variables that predict changes in HRQoL following cholecystectomy. METHODS: This was a prospective study of consecutive patients undergoing elective cholecystectomy for gallstones in six hospitals. Patients were asked to complete two questionnaires-the Short Form 36 (SF-36) and the Gastrointestinal Quality of Life Index (GIQLI)-before and 3 months after cholecystectomy. Multivariate linear regression models were used to examine factors potentially contributing to changes in HRQoL. RESULTS: Patients with symptomatic cholelithiasis and low surgical risk experienced the highest HRQoL gains in several SF-36 and GIQLI domains, with significant improvements in physical function detected by both instruments, compared with asymptomatic individuals at high surgical risk. Patients with asymptomatic cholelithiasis or high surgical risk experienced least improvement. CONCLUSION: These data indicate that cholecystectomy is appropriate for patients with symptomatic cholelithiasis and low surgical risk. In terms of HRQoL, the risk to benefit ratio seems poor for patients with asymptomatic gallstones.     

Responsiveness and Minimal Clinically Important Differences after Cholecystectomy: GIQLI Versus SF-36

Introduction  To compare responsiveness and minimal clinically important differences (MCID) between the Gastrointestinal Quality of Life (GIQLI) and the Short Form 36 (SF-36), we prospectively analyze 159 patients undergoing cholecystectomy at two tertiary academic hospitals. Patients and Methods  All patients completed the disease-specific GIQLI and the generic SF-36 before and 3 months after surgery. Scores using these instruments were interpreted by generalized estimating equation before and after cholecystectomy. The bootstrap estimation was used to derive 95% confidence intervals for differences in the responsiveness estimates. Results and Discussion  Mean changes in all GIQLI and the SF-36 subscales were statistically significant (p < 0.05). Comparisons of effect size (ES), standardized response means (SRM), and relative efficiency (>1) indicated that the responsiveness of the GIQLI was superior to that of the SF-36. In the equivalence test, all lower or upper confidence limits presented no equivalence (>5), indicating good MCID. The ES and SRM for emotions and physical function in the GIQLI significantly differed from those of the SF-36 (p < 0.05). Conclusion  The data in this study indicate that clinicians and health researchers should weight disease-specific measures more heavily than generic measures when evaluating treatment outcomes.     

Comparison of long-term quality of life after laparoscopic and open cholecystectomy

Background: Although many studies have compared open and laparoscopic procedures, showing many advantages in favor of the laparoscopic technique during the early postoperative period, only a limited number of reports in the literature compare the two techniques during the later follow-up period with regard to quality of life. This study aimed to compare the effects of these two cholecystectomy techniques on the quality of life and clinical outcome of the patients during long-term follow-up evaluation. Methods: This study evaluated 200 patients who underwent cholecystectomy operations with either technique between 1993 and 1999 in our department. There were 100 patients in each group. Both groups were similar with respect to age, gender, body mass indexes, American Society of Anesthesiology (ASA) scores, and indications for surgery. The Medical Outcome Study Short Form 36 Health survey (SF-36), which includes 36 items, was used for evaluating the quality-of-life index. In addition to this, a system-specific instrument for gastrointestinal diseases was used to investigate clinical outcome. Results: The mean administration time for the questionnaire was 46.8 ± 18.7 months in the laparoscopic cholecystectomy (LC) group and 41.5 ± 16 months in the open cholecystectomy (OC) group. Statistically significant differences were noted in the scores for all eight SF = 36 health status domains in favor of laparospopic surgery. No statistically significant difference was found for abdominal pain, location of the pain, referral to a doctor for the pain, accompanying symptoms, relieving factors for the pain, distention, and dyspeptic complaints, usage of antacid therapy, weight changes, changes in bowel habit, need for a special diet, or sexual functions between the two groups. Conclusions: The gastrointestinal clinical symptoms were similar in the two groups during the long-term follow-up evaluation, but laparoscopic cholecystectomy was found to be significantly superior to the open technique with respect to the quality of life over the long term.     

Up to one third of individual cardiac patients have a decline in quality of life post-intervention

OBJECTIVE: To investigate clinically relevant intra-individual and mean changes in health-related quality of life (HRQoL) with the Short Form-36 Health Survey (SF-36) need to acknowledge that SF-36 is trademarked ie: SF-36(R) following cardiac intervention for Australian and Danish patients. DESIGN: Prospective observational study in tertiary cardiac centres in Townsville, Queensland, Australia and Copenhagen, Denmark. Two hundred coronary artery bypass graft surgery (CABG) patients of two Townsville hospitals, and 47 CABG or percutaneous coronary intervention (PCI) patients of a Copenhagen hospital. The main outcome measures are eight SF-36 health subscales at baseline and six months post-intervention. RESULTS: Australian and Danish patients experienced similar HRQoL pre-intervention. By six months post-intervention, patients experienced a significant mean improvement in all subscales of the SF-36 survey (p < or = 0.05), although up to 27% of patients had a clinically significant decline in HRQoL from baseline. CONCLUSIONS: These results demonstrate that it is necessary to investigate intra-individual changes in HRQoL as well as group mean changes as they produce different conclusions. In addition, establishing clinically significant intra-individual change standards may assist researchers and clinicians in determining whether an individual may benefit from therapy or intervention.     

Using quality-of-life measurements to predict patient satisfaction outcomes for antireflux surgery

HYPOTHESIS: Preoperative quality-of-life measurement can predict which patients will be satisfied with surgical fundoplication in the treatment of gastroesophageal reflux disease (GERD). DESIGN: Review of a prospectively gathered database. SETTING: Tertiary referral center. PATIENTS: All patients underwent preoperative physiological testing by upper endoscopy, esophageal manometry, and 24-hour esophageal pH monitoring, and some had contrast radiography and gastric emptying scintigraphy. Patients were examined for symptoms and completed a symptom severity questionnaire (the GERD-Health-Related Quality of Life questionnaire) and a generic quality-of-life instrument (the 36-Item Short-Form Health Survey [SF-36]). Patients then underwent either open or laparoscopic fundoplication. MAIN OUTCOME MEASUREMENTS: Patients were contacted to assess satisfaction 2 months to 5 years postoperatively. They completed the GERD-Health-Related Quality of Life questionnaire and the SF-36. Patients were grouped into those satisfied and dissatisfied. RESULTS: Two hundred ninety patients were included. Median follow-up was 29 months. Thirty-four patients (12%) were dissatisfied with their surgical outcomes for any reason. The dissatisfied patients had statistically significantly worse scores preoperatively in 6 of the 8 domains of the SF-36 than satisfied patients. Dissatisfied patients had less symptomatic improvement. The satisfied patients had statistically significant improvement in 6 domains, whereas the dissatisfied patients had statistically significant worsening of scores in 2 domains. CONCLUSIONS: Quality-of-life measurements are frequently used as an outcome end point. This study shows that a generic quality-of-life instrument can preoperatively identify patients with GERD who are likely to be dissatisfied with antireflux surgery. Use of quality-of-life instruments as a predictive tool for surgical outcomes deserves further study.     

Laparoscopic-assisted versus open ileocolic resection for Crohn's disease: a randomized trial

OBJECTIVE: The aim of the study was to compare laparoscopic-assisted and open ileocolic resection for primary Crohn's disease in a randomized controlled trial. METHODS: Sixty patients were randomized for laparoscopic-assisted or open surgery. Primary outcome parameter was postoperative quality of life (QoL) during 3 months of follow-up, measured by SF-36 and GIQLI questionnaire. Secondary parameters were operating time, morbidity, hospital stay, postoperative morphine requirement, pain, and costs. RESULTS: Patient characteristics were not different. Conversion rate was 10% (n=3). Median operating time was longer in laparoscopic compared with open surgery (115 versus 90 minutes; P<0.003). Hospital stay was shorter in the laparoscopic group (5 versus 7 days; P=0.008). The number of patients with postoperative morbidity within the first 30 days differed between the laparoscopic and open group (10% versus 33%; P=0.028). There was no statistically significant difference in QoL between the groups during follow-up. Significant time effects were found on all scales of the SF-36 (P<0.001) and the GIQLI score (P<0.001). QoL declined in the first week, returned to baseline levels after 2 weeks, and was improved 4 weeks and 3 months after surgery. Median overall costs during the 3 months follow-up were significantly different: euro6412 for laparoscopic and euro8196 for open surgery (P=0.042). CONCLUSIONS: Although QoL measured by SF-36 and GIQLI questionnaires was not different for laparoscopic-assisted compared with the open ileocolic resection, morbidity, hospital stay, and costs were significantly lower.     

Laparoscopic versus small-incision cholecystectomy: Health status in a blind randomised trial

BACKGROUND: Gallstones are a major cause of morbidity, and cholecystectomy is a commonly performed procedure. Minimal invasive procedures, laparoscopic cholecystectomy (LC) and small-incision cholecystectomy (SIC), have replaced the classical open cholecystectomy. No differences have been found in primary outcome measures between LC and SIC, therefore secondary outcome measures have to be considered to determine preferences. The aim of our study was to examine health status applying evidence-based guidelines in LC and SIC in a randomised trial. METHODS: Patients with symptomatic cholecystolithiasis were included in a blind randomised trial. Operative procedures, anaesthesia, analgesics and postoperative care were standardised in order to limit bias. Questionnaires were filled in preoperatively, the first day postoperatively, and at outpatients follow-up at 2, 6 and 12 weeks. In accordance with evidence-based guidelines, the generic short form (SF-36) and the disease-specific gastrointestinal quality-of-life index (GIQLI) questionnaires were used in addition to the body image questionnaire (BIQ). RESULTS: A total of 257 patients were randomised between LC (120) and SIC (137). Analyses were performed according to intention-to-treat (converted procedures included) and also distinguishing converted from minimal invasive (nonconverted) procedures. Questionnaires were obtained with a response rate varying from 87.5% preoperatively to 77.4% three months postoperatively. Except for two time-specific measurements in one SF-36 subscale, there were no differences between LC and SIC. There were significant differences in several subscales in all three questionnaires comparing minimal invasive versus converted procedures. CONCLUSIONS: Applying adequate methodological quality and evidence-based guidelines (by using SF-36 and GIQLI), there are no significant differences in health status between LC and SIC.     

Assessment of long-term quality of life after laparoscopic and open surgery for Crohn''s disease

OBJECTIVE: Surgery for Crohn's disease (CD) is associated with a high recurrence rate and quality of life (QOL) in these patients is controversial. The aim of this study was to assess QOL in patients after laparoscopic and open surgery for CD by two different validated instruments, a generic nonspecific score and a specific gastrointestinal QOL index. PATIENTS AND METHODS: Patients with CD who underwent elective laparoscopic or open ileocaecal resection with primary anastomosis between 1992 and 2000 were followed for recurrence and surgery-related complications. QOL was assessed by the SF-36 Health Survey containing a mental (MCS) and a physical (PCS) component summary score and by the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch. RESULTS: Thirty-seven patients with a mean age of 48.8 +/- 18.4 years including 23 females and 14 males were evaluated at a mean follow-up of 42.6 +/-25.8 months (minimum of 8 months). Twenty-one (57%) patients underwent laparoscopic resection and 16 (43%) open surgery. Both groups were well matched for age, gender, ASA class and body mass index. Fourteen (38%) patients developed recurrent disease and 3 (8%) had postoperative incisional hernias. Overall, QOL scores were 103 +/- 26.8 for the GIQLI, 47.2 +/- 11.8 for the PCS, and 49.2 +/- 11.5 for the MCS. The GIQLI correlated well with the SF36, correlation coefficient = 0.68 for GIQLI vs PCS (95% CI, 0.41,0.95) and 0.67 for GIQLI vs MCS (95%CI, 0.39, 0.95), respectively. When compared to the general US population, mean GIQLI scores (-13.8, P = 0.002) and mean PCS scores (-4.7, P = 0.001) were significantly lower in these patients than in healthy individuals. In a multivariate analysis of impact factors on QOL, recurrence within the follow-up period was the single significant determinant reducing the PCS (-35.1, P = 0.026) and the GIQLI (-36.1, P = 0.018). CONCLUSION: QOL is significantly reduced in patients with CD at long-term follow-up after both laparoscopic and open surgery. Recurrence is the only factor adversely affecting QOL of CD patients in remission irrespective of the operative technique applied.     

Up to one third of individual cardiac patients have a decline in quality of life post-intervention

Objective. To investigate clinically relevant intra-individual and mean changes in health-related quality of life (HRQoL) with the Short Form-36 Health Survey (SF-36) need to acknowledge that SF-36 is trademarked ie: SF-36® following cardiac intervention for Australian and Danish patients. Design. Prospective observational study in tertiary cardiac centres in Townsville, Queensland, Australia and Copenhagen, Denmark. Two hundred coronary artery bypass graft surgery (CABG) patients of two Townsville hospitals, and 47 CABG or percutaneous coronary intervention (PCI) patients of a Copenhagen hospital. The main outcome measures are eight SF-36 health subscales at baseline and six months post-intervention. Results. Australian and Danish patients experienced similar HRQoL pre-intervention. By six months post-intervention, patients experienced a significant mean improvement in all subscales of the SF-36 survey (p?≤?0.05), although up to 27% of patients had a clinically significant decline in HRQoL from baseline. Conclusions. These results demonstrate that it is necessary to investigate intra-individual changes in HRQoL as well as group mean changes as they produce different conclusions. In addition, establishing clinically significant intra-individual change standards may assist researchers and clinicians in determining whether an individual may benefit from therapy or intervention.     

Health-related quality of life and appropriateness of cholecystectomy

OBJECTIVE: To evaluate the relationship among appropriateness of the use of cholecystectomy and outcomes. SUMMARY BACKGROUND DATA: The use of cholecystectomy varies widely across regions and countries. Explicit appropriateness criteria may help identify suitable candidates for this commonly performed procedure. This study evaluates the relationship among appropriateness of the use of cholecystectomy and outcomes. METHODS: Prospective observational study in 6 public hospitals in Spain of all consecutive patients on waiting lists to undergo cholecystectomy for nonmalignant disease. Explicit appropriateness criteria for the use of cholecystectomy were developed by a panel of experts using the RAND appropriateness methodology and applied to recruited patients. Patients were asked to complete 2 questionnaires that measure health-related quality of life-the Short Form 36 (SF-36) and the Gastrointestinal Quality of Life Index (GIQLI)-before the intervention and 3 months after it. RESULTS: Patients judged as being appropriate candidates for cholecystectomy, using the panel's explicit appropriateness criteria, had greater improvements in the bodily pain, vitality, and social function domains of the SF-36 than those judged to be inappropriate candidates. They also demonstrated improvements in the GIQLI's physical impairment domain. Interventions judged as inappropriate were performed primarily among patients without symptoms of cholelithiasis. Those asymptomatic had a lower improvement in the bodily pain, social functioning, and physical summary scale of the SF-36 and in the symptomatology, physical impairment, and total score domains of the GIQLI. CONCLUSIONS: These results suggest a direct relationship between the application of explicit appropriateness criteria and better outcomes, as measured by health-related quality of life. They also indicate that patients without symptoms are not good candidates for cholecystectomy.     

Laparoscopic vs open surgery

BACKGROUND: The purported advantages of laparoscopic surgery over conventional open techniques are less pain and faster return to normal functional status. Very few studies have included validated measures of quality of life as end points. This study prospectively assessed the health status outcomes of patients undergoing four types of laparoscopic and open operations. METHODS: Preoperatively, patients undergoing elective inguinal hernioplasty, esophageal surgery, cholecystectomy, and splenectomy completed the SF-36, a well-tested, validated health-status instrument. This instrument measures physical functioning (PF), role-physical (RP), role-emotional (RE), bodily pain (BP), vitality (VT), mental health (MH), social functioning (SF), and general health (GH) health status domains. Patients then underwent either laparoscopic or open surgery. Patients were reassessed with the instrument > or =6 weeks after surgery. A total of 100 patients underwent these procedures. RESULTS: Compared to preoperative values, median SF-36 scores for laparoscopic cholecystectomy patients were improved in the domains of PF (85 vs 95, p = 0.01), BP (42 vs 75, p = 0.002), and VT (47.5 vs 70, p = 0.04); open cholecystectomy patients did not show statistically significant improvements over preoperative values. In addition, laparoscopic cholecystectomy patients had a better score than open cholecystectomy patients in the BP domain (75 vs 41, p = 0.05). Laparoscopic esophageal surgery patients had better scores than open surgery patients in the domains of RP (100 vs 0, p = 0.02) and VT (65 vs 52.5, p = 0.05). Compared to preoperative values, laparoscopic splenectomy patients had an improved score in GH (52 vs 77, p = 0.02) and better scores than open splenectomy patients in PF (90 vs 45, p = 0.05) and BP (84 vs 55.5, p = 0.01). Compared to preoperative values, open mesh hernioplasty patients showed improved scores in PF (70 vs 92.5, p = 0.03) and MH (72 vs 84, p = 0.05). Laparoscopic hernioplasty did not produce improved scores compared to either preoperative values or open hernioplasty. CONCLUSIONS: Laparoscopic surgery has demonstrably better quality-of-life outcomes than open surgery for cholecystectomy, splenectomy, and esophageal surgery. However, open hernioplasty has at least as good, if not better, health status outcomes than laparoscopic repair.     

The effect of long saphenous vein stripping on quality of life

PURPOSE: Long saphenous vein (LSV) stripping in the treatment of varicose veins may reduce the recurrence of varices but may also increase morbidity rates. The effect of stripping on health-related quality of life (HRQoL) is unknown. The aim of this study was to examine the effect of LSV surgery, with and without successful stripping, on HRQoL. METHODS: This prospective study comprises 102 consecutive patients who underwent varicose vein surgery that included attempted stripping of the LSV to the knee. HRQoL was assessed before surgery and at 4 weeks, 6 months, and 2 years after surgery with the Aberdeen varicose vein severity score (AVSS; disease-specific) and the Short-Form 36 (SF-36; generic). Patients defined as stripped were those in whom complete thigh stripping to the knee was confirmed with postoperative duplex scanning at 2 years. Patients defined as incompletely stripped were those in whom any LSV remnant was found in the thigh after surgery. Deep venous reflux (DVR) was defined as reflux of 0.5 seconds or more in at least the popliteal vein. RESULTS: Sixty-six of 102 patients (65%) provided complete HRQoL data at all four time points. At baseline, there was no significant difference between patients who were stripped (n = 25) and incompletely stripped (n = 41) in terms of AVSS, SF-36, age, gender, DVR, or CEAP grade. Significantly more patients in the incompletely stripped group underwent surgery for recurrent disease (29/41, 71%, versus 8/25, 32%; P =.002, with chi(2) test). Both groups gained significant improvements in AVSS scores for as much as 2 years. After adjustment for recurrent disease, stripping conferred additional benefit in terms of AVSS at 6 months (median [interquartile range]) (9 [4 to 16] versus 15 [9 to 24]; P =.031) and 2 years (7 [2 to 10] versus 9 [5 to 15]; P =.014), which was statistically significant in patients without preoperative DVR but not significant in patients with preoperative DVR. SF-36 scores were not affected by stripping. CONCLUSION: LSV surgery leads to a significant improvement in disease-specific HRQoL for as much as 2 years. In patients without DVR, stripping to the knee confers additional benefit.     

Health-related quality of life after retroperitoneoscopic and hand-assisted laparoscopic nephrectomy

BACKGROUND AND PURPOSE: The assessment of postoperative recovery typically involves the use of measures that are open to bias. Whilst there has been some work done on the short-term postoperative recovery comparison for hand-assisted laparoscopic nephrectomy (HALN) and retroperitoneoscopic nephrectomy (RPN), to our knowledge, this is the first study to look at long-term health outcomes for these two procedures. This study sought objectively to compare long-term postoperative health-related quality of life (HRQoL) after retroperitoneoscopic and hand-assisted transperitoneal laparoscopic nephrectomy undertaken for renal pathology. This was achieved by both reviewing perioperative data from medical records and by using the SF-36 questionnaire postoperatively. PATIENTS AND METHODS: Patients who had undergone elective retroperitoneoscopic (N = 19) or transperitoneal HALN (N = 32) between 2001 and 2004 at our institution underwent objective HRQoL assessment via a validated telephone questionnaire (SF-36) and by review of postoperative data from the medical records. This survey was administered between 3 and 6 months after surgery. The data then underwent statistical analysis using the paired Student's t-test. RESULTS: Perioperative data showed no significant difference in the postoperative complication rate in the two groups. The HRQoL scores gathered from the SF-36 questionnaire gave mean scores of 67.4 and 68.5 for the HALN and RPN groups, respectively (100 represents maximum quality of life). This difference was not statistically significant. CONCLUSIONS: This is the first study to look at long-term (mean follow-up 6 months) health outcomes for patients undergoing RPN and HALN. The results show no greater long-term health benefit for one procedure over the other. This finding supports the data in the literature on the benefits of HALN over RPN in terms of a less protracted learning curve, greater technical ease, fewer intraoperative complications, and consequently reduced operating times with no loss of the long-term health benefit that is traditionally associated with the standard laparoscopic technique.     

Health-related quality of life in patients with skull base tumours

The objective of the investigation was to report on the health-related quality of life (HRQoL) of patients diagnosed with skull base tumours using the Short Form Health Survey questionnaire (SF-36). Those patients suffering with vestibular schwannoma were examined to determine the effect facial nerve function had on their quality of life. It took place at the tertiary referral centre at the Department of Clinical Neurosciences, Western General Hospital, Edinburgh. A prospective study of 70 consecutive patients was taken, who harboured the following tumours: 54 vestibular schwannomas, 13 meningiomas, two haemangioblastomas and one hypoglossal schwannoma. Patients were interviewed using the short form 36 (SF-36) questionnaire. Facial nerve function was assessed in those patients who had vestibular schwannomas. The entire cohort of live skull base patients were assessed after a median follow-up time of 38.4 months. Patients with vestibular schwannoma treated conservatively with interval MRI had a quality of life similar to t he normal population. Those who underwent surgery had a significant difference in two of the SF-36 domains. No statistically significant correlation was found at final assessment between the degree of facial nerve functioning and any of the domains of SF-36. Patients with non-vestibular tumours had an impaired HRQoL in seven of the eight domains. Patients with skull base tumours have a significant impairment of their HRQoL. A conservative policy of follow up with interval MRI for patients with small vestibular schwannomas may therefore be more appropriate to preserve their HRQoL. Facial nerve outcome has little influence on quality of life in vestibular schwannoma patients.     

Quality of life after laparoscopic bilateral adrenalectomy for Cushing's disease

BACKGROUND: Bilateral adrenalectomy to control symptoms of Cushing's disease after failed transsphenoidal operation is effective. We examined surgical outcomes and quality of life after laparoscopic bilateral adrenalectomy for the treatment of Cushing's disease. METHODS: Eighteen patients underwent laparoscopic bilateral adrenalectomy from November 1994 through December 2000. Patient data were obtained from chart reviews. Patients completed a follow-up survey including the SF-36 health survey (QualityMetric Inc, Lincoln, Neb). RESULTS: Laparoscopic bilateral adrenalectomy was accomplished in all 18 patients. There was 1 intraoperative complication of a colotomy, and 2 postoperative complications including 1 pancreatic pseudocyst and 1 hemorrhage. Three patients died at 12, 19, and 50 months after operation. At a median follow-up of 29 months, patients reported improvement in all Cushing's-related symptoms. Nine of 11 patients who responded to the survey stated their heath was improved after adrenalectomy. Results of the SF-36 health survey showed significantly lower scores in all 8 measured parameters when compared with the general population. CONCLUSIONS: Results of laparoscopic bilateral adrenalectomy show this procedure is comparable with open adrenalectomy in controlling symptoms of Cushing's disease. Despite patient reported improvement in health after adrenalectomy, this patient population continues to experience poor health as measured by the SF-36 when compared with the general population.     

Quality-of-life assessment of surgical reconstruction after laparoscopic cholecystectomy-induced bile duct injuries: what happens at 5 years and beyond?

HYPOTHESIS: Quality of life of patients after biliary reconstruction for laparoscopic injuries is comparable to that of patients after laparoscopic cholecystectomy. DESIGN: Outcomes study. SETTING: Tertiary referral center. PATIENTS: Records of 59 consecutive patients undergoing surgical reconstruction of the biliary tract after injury induced by laparoscopic cholecystectomy between 1990 and 1997 were reviewed. Hepp-Couinaud technique or Roux-en-Y hepaticojejunostomy was used in 53 patients; other procedures included cholangiojejunostomy, choledochorrhaphy, and hepaticoduodenostomy. INTERVENTIONS: Quality-of-life questionnaires (36-Item Short-Form Health Survey [SF-36]) were mailed to each patient in the group and to patients who underwent uneventful laparoscopic cholecystectomy, matched individually by year, sex, and age group. Values from the general population matched by age and sex were gathered (national norms). Minimum time of follow-up was 5 years. RESULTS: Eighty-nine (81%) of 110 potential respondents to the survey completed the SF-36 questionnaires. All 8 values evaluated in the SF-36 questionnaire (physical functioning, role-physical, bodily pain, general health perceptions, vitality, social functioning, role-emotional, and mental health index) for patients undergoing biliary reconstruction were similar to those of both their matched controls (all P >.10) and national norms (all P >.05). The standardized physical component scale was also similar between the 2 groups (cases vs controls, 51 vs 48; P =.47), as was the standardized mental component scale (cases vs controls, 55 vs 55; P =.60). CONCLUSIONS: With a minimum of 5 years of follow-up, the quality of life after surgical biliary reconstruction compares favorably with that of both patients undergoing uneventful laparoscopic cholecystectomy and national norms.     

Quality of life following lung cancer surgery

BACKGROUND: Patients with non-small cell bronchogenic carcinoma have a limited survival. Quality of life (QoL) is therefore an issue of importance in this group of patients. The aim of the present study was to evaluate QoL in lung cancer patients after open surgery. METHODS: During a 4 year period (1997-2000) 194 patients with primary bronchogenic carcinoma of the lung underwent surgery at the Department of Thoracic and Cardiovascular Surgery in Uppsala, Sweden; 132 patients were alive on 1 April 2001. These patients received the Short Form-36 (SF-36) health questionnaire, Hospital Anxiety and Depression (HAD) scale, and special questions related to pulmonary symptoms (response rate 85%). Patients who underwent coronary bypass surgery (CABG) served as a comparison group (response rate 91%). Corresponding estimates of QoL in healthy controls were obtained from the SF-36 manual for the Swedish population. RESULTS: Lung cancer patients differed from CABG patients in only one subgroup of the SF-36 (role physical), but had poorer QoL than healthy controls. No difference in anxiety was found between the lung cancer patients and the CABG patients, but the latter were more likely to suffer from depression (5.0% v 3.0%). Current smokers scored lower in the mental health dimension assessment. CONCLUSION: Lung cancer patients who undergo open traditional surgical resection have a QoL comparable to that of CABG patients. Lung cancer patients have poorer physical function because of reduced pulmonary function, but show no sign of increased anxiety or depression. Those who continued to smoke after surgery had impaired mental health.     

Health-related quality of life during the first year after severe brain trauma with and without polytrauma

OBJECTIVE: The increasing number of patients surviving severe traumatic brain injury (sTBI) but with significant sensorimotor and neuropsychological deficits is a challenge to rehabilitation medicine. So far, most research initiatives have focused on mortality rates, physiological or economic parameters to estimate therapeutic effects of rehabilitation strategies. Investigations on health-related quality of life (HRQoL) after TBI with and without concomitant polytrauma are rare compared to other disorders. DESIGN/PATIENTS: A prospective study was conducted to investigate HRQoL using the SF-36 questionnaire in 49 patients with sTBI (Glasgow Coma Scale < 9 for more than 24 hours) with and without concomitant polytrauma 6 and 12 months after injury. RESULTS: The SF-36 score profiles 6 and 12 months after trauma were similar. Scores 12 months after trauma, however, were higher in 7/8 dimensions indicating an improvement over time. Similar observations were made for physical and mental sum scores. There was no difference in the SF-36 scoring pattern between the patients with isolated TBI and the patients with concomitant polytrauma, except for physical functioning after 12 months. CONCLUSION: While there is significant overall improvement of HRQoL over time, sTBI appears to bear major influence on post-traumatic HRQoL and outcome.     

Health-related quality of life in morbidly obese patients: effect of gastric bypass surgery

Background: The effect of gastric bypass on the health-related quality of life (HRQoL) of morbidly obese patients was investigated in a cross-sectional study. Methods: A postoperative group of 78 patients on average 13.8 years after gastric bypass was compared with a preoperative control group of 110 patients. The SF-36 was used to assess HRQoL. In preoperative patients, the SF-36 was self-administered, while in the postoperative group, telephone interviews were conducted. In the postoperative sample, multiple stepwise linear regression analyses were carried out to examine putative predictors of the physical (PCS) and the mental (MCS) composite scores of the SF-36. Results: Significant differences between the preand postoperative group were found for all subscales except Mental Health, in favor of the postoperative group. On average 13.8 years after gastric bypass, most of the sub-scales were similar to the US norm values. However, the Bodily Pain and the overall Physical Composite scale (PCS) scores were lower (more impaired) in the postoperative group compared with the US norms. Female patients, patients who were hospitalized since the surgery, and those who had lost less weight had more impaired values on the PCS and patients who reported binge-eating disorder (BED) at follow-up had more impaired values on the Mental Composite Scale (MCS) of the SF-36. Conclusion: HRQoL was significantly better in postoperative gastric bypass patients in comparison to a sample of preoperative patients. However, HRQoL, specifically the physical domain of the SF-36, was more impaired in long-term follow-up patients compared with US norm values. The reoccurrence of BED after surgery negatively influenced the mental domain of the SF-36.     

Ambulatory and admitted laparoscopic cholecystectomy patients have comparable outcomes but different functional health status

BACKGROUND: Laparoscopic cholecystectomy is frequently an ambulatory procedure, but some patients are best admitted for a brief hospital stay. In this study, we compared the functional health status, symptoms, and outcomes of patients undergoing ambulatory elective laparoscopic cholecystectomy to those with brief hospital admission. The purpose was to assess patient satisfaction and to identify factors that might assist in selecting patients for ambulatory vs short-stay operations. METHODS: A total of 140 patients scheduled for elective cholecystectomy completed the SF-36 health survey and provided additional information regarding symptoms preoperatively, at 2 months, and at 6 months after operation. RESULTS: All patients had symptomatic gallstones; 76 were admitted to the hospital, and 64 were ambulatory. Admitted patients reported more emotional role limitations on preoperative SF-36. They also reported symptoms of depression more often. Patients in both groups were equally relieved of symptoms of pain, nausea, vomiting, and tenderness. Satisfaction with care was similar for both groups; however, at 2 and 6 months, admitted patients continued to report significantly poorer functional health status than ambulatory patients. CONCLUSION: A reliable, reproducible measure of functional health status, such as the SF-36, may be useful for identifying patients who are appropriate for short-stay hospital admission after laparoscopic cholecystectomy as part of a decision process that tries to optimize outcomes while utilizing resources efficiently.
