Quality-of-life assessments in evaluation of laparoscopic Rosetti fundoplication

It has recently been suggested that quality-of-life investigations should be included in the evaluation of new medical and surgical regimens. We present the quality-of-life evaluations for the first 40 consecutive patients undergoing laparoscopic antireflux surgery at our department. Two well-established and validated questionnaires, the Psychological General Well Being (PGWB) Index, and the Gastrointestinal Symptom Rating Scale (GSRS), were used. The PGWB gives a general measure of patients' well-being while the GSRS concentrates on gastrointestinal complaints. In untreated reflux esophagitis patients, the PGWB score is very low. We found normal PBWB scores preoperatively during optimal medical treatment with potent acid inhibition. The average score became significantly better (than on medical treatment, P<0.05) 1 month postoperatively, after which it fell off to normal values 3 and 8–12 months after operation. The GSRS scores were good in all subgroups postoperatively, especially regarding reflux syndrome, where scores were significantly (P<0.05) better than on medical treatment.In conclusion: After laparoscopic antireflux surgery, patients had good quality-of-life scores, better than untreated patients and as good as or better than on optimal medical treatment. Different treatment regimens could be discriminated by adding the patients' view of the treatment effect. We suggest that quality-of-life effects should be included when evaluating new regimens in laparoscopic surgery.Presented at the annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons (SAGES), Nashville, Tennessee, USA, 18–19 April 1994     

Randomized clinical trial of laparoscopic Nissen fundoplication compared with proton-pump inhibitors for treatment of chronic gastro-oesophageal reflux

BACKGROUND: Both laparoscopic Nissen fundoplication (LNF) and proton-pump inhibitor (PPI) therapy are established in the treatment of gastro-oesophageal reflux disease (GORD). The aim of this study was to compare these two treatments in a randomized clinical trial. METHODS: Between July 1997 and August 2001, 340 patients with a history of GORD for at least 6 months were investigated by endoscopy, 24-h pH monitoring and manometry. Of these, 217 were randomized, 109 to LNF and 108 to PPI therapy. The two groups were well matched for age, sex, weight and severity of reflux. Twenty-four-hour pH monitoring and manometry were performed 3 months after treatment, and quality of life was assessed in both groups using the Psychological General Well-being Index and the Gastrointestinal Symptom Rating Scale at 3 and 12 months after treatment. RESULTS: At 3 months there was an improvement in lower oesophageal sphincter pressure from 6.3 to 17.2 mmHg in the LNF group but no change in the PPI group (8.1 and 7.9 mmHg before and after treatment respectively) (P < 0.001). The mean DeMeester acid exposure score improved from 42.7 to 8.6 (P < 0.001) in the LNF group and from 36.9 to 17.7 in the PPI group (P < 0.001). The mean gastrointestinal symptom and general well-being scores improved from 31.7 and 95.4 respectively before treatment to 37.0 and 106.2 at 12 months after LNF, compared with changes from 34.3 and 98.5 to 35.0 and 100.4 respectively in the PPI group. The differences in both of these scores were significant between the two groups at 12 months (P = 0.003). CONCLUSION: LNF leads to significantly less acid exposure of the lower oesophagus at 3 months and significantly greater improvements in both gastrointestinal and general well-being after 12 months compared with PPI treatment.     

Comparison of patient-centered outcomes after laparoscopic Nissen fundoplication for gastroesophageal reflux disease or paraesophageal hernia

Background Patients undergoing laparoscopic Nissen fundoplication (LNF) with paraesophageal hernias (PEH) are not only older and less healthy than those with gastroesophageal reflux disease (GERD), but in addition the repair is more complicated. We evaluated whether outcomes relating to GERD symptoms and quality of life (QOL) were impacted by the presence of PEH. Methods Prospectively entered data from 149 patients (109 GERD and 40 PEH) were evaluated prior to and one year after LNF with standardized and validated symptoms scores. Scores for heartburn, dysphagia, disease-specific QOL (GERD-HRQL), and general health-related QOL (SF-12 physical and mental component scores) were compared between patients undergoing LNF for PEH or for GERD alone, at baseline and one year after surgery. p < 0.05 was considered statistically significant. Results Preoperative data for GERD-HRQL, heartburn, and dysphagia were available for 134 patients, with 96% one-year follow-up. SF-12 data were collected for 98 patients with 100% follow-up. PEH patients were older and had greater comorbidity. Preoperative GERD-HRQL and heartburn were significantly worse in the GERD group. One year after surgery, both GERD and PEH patients showed significant improvement in GERD-HRQL, heartburn and dysphagia scores, with no difference in any of these disease or symptom measures between the two study groups. Postoperative PCS and MCS scores showed improvement in GERD patients, while PEH patient scores remained at or below the population mean. Conclusions LNF is equally effective as an antireflux procedure in both GERD and PEH patients, prevents symptoms of reflux in PEH patients that have none preoperatively, and does not increase dysphagia in either group. Despite the increased complexity of the procedure, LNF provides an effective control of reflux symptoms in patients undergoing PEH repair.

The prevalence of gastrointestinal symptoms in patients with chronic renal failure is increased and associated with impaired psychological general well-being.

BACKGROUND: Malnutrition occurs frequently in patients with end-stage renal disease (ESRD). Gastrointestinal (GI) symptoms may lead to reduced food intake, resulting in malnutrition and impaired well-being in these patients. The prevalence of GI symptoms in various chronic renal failure (CRF) groups is unexplored. We assessed the prevalence of GI complaints in patients on either haemodialysis (HD), peritoneal dialysis (PD), or in the pre-dialysis stage. Patients with and without diabetic nephropathy were also compared. METHODS: A total of 233 patients with CRF (128 HD, 55 PD, and 50 pre-dialytic patients) completed two self-administered questionnaires: the Psychological General Well-Being (PGWB) index and the Gastrointestinal Symptom Rating Scale (GSRS), which measures GI symptoms. The values were compared with reference values obtained from the general population. The association between GI symptoms and serum (s-)albumin was also studied. RESULTS: The total GSRS score in patients with CRF was significantly higher than the reference values (HD 2.14 (1.97-2.31), PD 2.24 (2.00-2.48), and pre-dialytic patients 2.03 (1.82-2.25) vs controls 1.53 (1.50-1.55; P<0.001). When comparing CRF subgroups there was no overall difference between the groups, but PD patients had more severe reflux and eating dysfunction. In patients with diabetic nephropathy, only eating dysfunction was significantly more common than in the non-diabetic patients. There was a negative correlation between GI symptoms and psychological general well-being in CRF patients (Rho=-0.46, P<0.001) indicating that patients with a high GI symptom profile have impaired psychological general well-being. A negative correlation was found between eating dysfunction and s-albumin (Rho=-0.33, P<0.01). CONCLUSION: The prevalence of GI symptoms is high in patients with CRF and is associated with impairment in psychological general well-being. Presence of dialysis or not, type of dialysis, and presence or absence of diabetes mellitus seem to have limited impact on GI symptoms.     

Gastroesophageal disease and nausea: does fundoplication help or hurt?

HYPOTHESIS: Nausea associated with gastroesophageal reflux disease is cured by laparoscopic Nissen fundoplication (LNF). DESIGN: Prospective cohort study of unselected patients who underwent LNF from January 1, 1995, through March 31, 1999. Patients were followed up by a physician for 6 to 36 months. SETTING: A large community teaching hospital. PATIENTS: One hundred consecutive patients with gastroesophageal reflux disease who underwent LNF; all patients were followed up. Patients were grouped according to the presence (group A, n = 33) or absence (group B, n = 67) of preoperative nausea. Interventions were LNF, esophageal manometry, 24-hour pH monitoring, and nuclear gastric emptying studies. MAIN OUTCOME MEASURES: Resolution of symptoms after LNF. RESULTS: Nausea was the most common atypical symptom of gastroesophageal reflux disease, occurring in 33 patients (33%). There were no differences in esophageal manometry or 24-hour pH results between groups. There was a female preponderance in group A (55% vs 33%; P = .003). Patients in group A had a higher prevalence of preoperative dysphagia (P = .02). Patients with persistent postoperative nausea had a higher prevalence of cough (P = .003) and dysphagia (P = .009). The LNF was more effective in reducing heartburn (95% reduction) and regurgitation (95% reduction) than cough and dysphagia (60% reduction). There was a 79% reduction in the number of patients with nausea (33 to 7; P<.001). CONCLUSION: Laparoscopic Nissen fundoplication is effective in eliminating nausea associated with gastroesophageal reflux disease and is not contraindicated in these patients.     

Laparoscopic fundoplication

BACKGROUND: The effectiveness of laparoscopic Nissen fundoplication (LNF) was assessed in patients with chronic gastroesophageal reflux disease (GERD) using pH study and different quality-of-life indexes. We correlated both types of data and hypothesised that improvement in quality of life following LNF does not necessarily correlate with improvement in pH values. METHODS: Seventy patients presenting with typical symptoms of GERD (14 with Barrett's esophagus) underwent LNF between May 1997 and December 2000. All patients were evaluated both prior to and 3 months after surgery using 24-h pH study, endoscopy, and a validated quality-of-life questionnaire. RESULTS: Following LNF, reflux was reduced to normal in all but six patients. Howevers despite persistent reflux, the Gastrointestinal Quality of Life Index (GQLI), of these six patients improved postoperatively from 79.5 +/- 12.2 to 111.7 +/- 8.3. These results correlate with those of patients who had normal postoperative pH studies-namely, 88.5 +/- 19.3 to 112 +/- 16.7. There was no difference in quality-of-life improvement between patients with Barrett's esophagus and those without it. CONCLUSION: There is only a weak correlation between quality-of-life assessment and pH study. Because the patient's quality of life is likely to improve following LNF, an objective means parameter of assessing the effectiveness of antireflux surgery, such as pH study or endoscopy, is recommended.     

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.     

Is the use of a bougie necessary for laparoscopic Nissen fundoplication?

HYPOTHESIS: Esophageal intubation with a bougie during laparoscopic Nissen fundoplication (LNF) is commonly used to prevent an excessively tight wrap. However, a bougie may cause intraoperative gastric and esophageal perforations. We hypothesized that LNF is safe and effective when performed without a bougie. DESIGN: Retrospective review of 102 consecutive patients who underwent LNF without a bougie. SETTING: Tertiary care university hospital. PATIENTS: All patients presented with symptoms of reflux disease. Mean (+/- SD) percentage of time with pH of less than 4 was 12.6% +/- 9.4%. Mean DeMeester score was 47.8. Mean (+/- SD) resting lower esophageal sphincter pressure was 15.0 +/- 9.4 mm Hg. Mean (+/- SD) distal esophageal amplitude was 69.4 +/- 39.2 mm Hg. INTERVENTION: During LNF, we obtained 2 to 3 cm of intra-abdominal esophagus, divided all short gastric vessels, reapproximated the crura, and performed a loose 360 degrees fundoplication without a bougie. MAIN OUTCOME MEASURES: Postoperative rates of dysphagia, gas bloat, and recurrent reflux. RESULTS: In the early postoperative period, 50 patients (49.0%) complained of mild, 11 (10.8%) of moderate, and 7 (6.9%) of severe dysphagia. Average (+/- SD) duration of early dysphagia was 4.6 +/- 2.1 weeks. Dysphagia resolved in 61 (89.7%) of 68 patients within 6 weeks. Late resolution of dysphagia was noted in 4 (5.8%) patients. Three patients were successfully treated with esophageal dilatations. Persistent dysphagia was found in 1 patient. Thirty patients (29.4%) had transient gas bloat. Mild persistent reflux, requiring daily medication, was noted in 5 (4.9%) patients. CONCLUSIONS: Performance of LNF without a bougie offers a safe and effective therapy for gastroesophageal reflux disease. While avoiding the potential risks for gastric and esophageal injury, it may provide low rates of long-term postoperative dysphagia and reflux recurrence.     

Laparoscopic versus open fundoplication in infants

BACKGROUND: Laparoscopic esophagogastric fundoplication is an effective treatment for severe gastroesophageal reflux disease (GERD), although its role in the very young is still largely undetermined. We review our surgical outcome in infants with severe GERD, comparing laparoscopic (LNF) with open (ONF) Nissen fundoplication. METHODS: This study reviewed 55 consecutive Nissen fundoplications performed for GERD on infants less than 1 year old at our institution between January 1996 and June 2000. The follow-up period for LNF averaged 14.2 months (range, 3.3-42 months), as compared with 16.5 months (range, 1-37.1 months) for ONF (p was not significant, t-test). Surgical outcome was compared in terms of the following parameters: average operative time, times to initiation and completion of feeding schedule, postoperative complications, and recurrence rates. RESULTS: For the study, 53 infants were divided into two groups: LNF (n = 39; 73.6%) and ONF (n = 14; 26.4%). The average operating time for LNF was 120 +/- 24 min (range, 60-195 min), as compared with 91 +/- 21 min (range, 60-135 min) for ONF (p < 0.05, t-test). Time to initiation of postoperative feeding schedule was 1.3 +/- 0.3 days for LNF, as compared with 3 +/- 0.9 days for ONF (p < 0.05, t-test). Full feedings were reached in 1.7 +/- 0.6 days for LNF, as compared with 1.3 +/- 0.9 for ONF (p was not significant, t-test). During the short-term follow-up period, recurrent reflux developed in 2/14 ONF patients (14.3%) as compared with 1/39 LNF patients (2.6%) (p < 0.05). CONCLUSIONS: We conclude that in addition to sparing infants the morbidity of celiotomy, laparoscopic Nissen fundoplication had a surgical outcome comparable to that of traditional open fundoplication in infants with severe GERD. Importantly, resumption of goal nutritional regimens was equally efficient in both groups.     

Preoperative symptom evaluation and esophageal acid infusion predict response to laparoscopic Nissen fundoplication in gastroesophageal reflux patients who present with cough

BACKGROUND: Most patients with cough and gastroesophageal reflux disease (GERD) improve on medical treatment with proton pump inhibitors (PPI). Nonresponders may be considered for antireflux surgery, but the selection of patients is difficult. METHODS: We have performed laparoscopic Nissen fundoplications (LNF) in 677 patients. Of these patients, 81% have undergone 6-month follow-up assessment with 24-h pH testing, esophageal manometry, symptom scores, and quality-of-life scores. RESULTS: LNF controlled heartburn in 93% and improved cough in 81%. Stepwise multiple regression showed that the preoperative cough score (r = 0.620, p <0.0001) and change in cough on and off PPI (r = 0.296, p = 0.0002) predicted improvement after surgery. A positive result on a randomized acid infusion test was associated with a greater improvement in cough after surgery (p = 0.0243). CONCLUSION: An acid infusion test and assessment of cough on and off PPI may be useful preoperative tools for the selection of patients with cough for LNF.     

Prospective study of laparoscopic nissen fundoplication in a community hospital and its effect on typical, atypical, and nonspecific gastrointestinal symptoms.

BACKGROUND: Laparoscopic Nissen fundoplication (LNF) provides long-term improvement in the typical symptoms of gastroesophageal reflux disease. Few studies have prospectively addressed LNF in the community hospital or the effect of LNF on specific atypical symptoms, other related gastrointestinal symptoms, and weight change. METHODS: Data were collected prospectively on consecutive patients having LNF. Three typical, 6 atypical, and 3 other gastrointestinal symptoms were studied. RESULTS: Short-term data on 91 patients and long-term data on 84 patients were studied. Overall long-term improvement was 98%. Regarding typical symptoms, the greatest improvement occurred in heartburn and regurgitation. Regarding atypical symptoms, the greatest improvement occurred in cough and sore throat, but chest pain, hoarseness, and throat clearing also showed significant durable improvement. Bloating, nausea, and diarrhea showed no significant change from preoperative to postoperative surveys. Mild weight loss was common. CONCLUSION: LNF can be safely performed in a community hospital with results equal to those of university hospitals. Improvement in typical symptoms was greater than improvement in atypical symptoms, but results for both were significant and durable. Nonspecific gastrointestinal symptoms, such as nausea, bloating, and diarrhea, may be unrelated to Nissen fundoplication.     

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.     

Results of laparoscopic fundoplication where atypical symptoms coexist with oesophageal reflux

BACKGROUND: Laparoscopic Nissen fundoplication (LNF) has been increasingly performed for gastro-oesophageal reflux disease. The outcomes of LNF for patients with concurrent symptoms other than heartburn are unclear. The purpose of the present paper was to review the outcomes of LNF performed by one surgeon over 4 years and compare the outcomes of patients with reflux symptoms with those of patients having reflux symptoms plus atypical symptoms. METHODS: The records of a consecutive series of 90 patients were reviewed. Preoperative symptoms were defined as typical (heartburn and reflux) or atypical (other symptoms, e.g. cough, atypical chest pain, choking). At the time of follow up an independent observer interviewed patients, and collected data on current symptoms and patient satisfaction. A questionnaire of current symptoms and patient satisfaction was completed. A satisfaction score from 1 to 10 was given by patients, with 1 being very unsatisfied and 10 being very satisfied. RESULTS: Of the 90 patients, 97% had typical symptoms and 56% had concurrent atypical symptoms. Eighty-three of 90 patients were contacted; typical reflux symptoms improved in 95% of patients whereas atypical symptoms improved in only 54%. Overall, the mean satisfaction score was 8.7. Patients with atypical symptoms had a lower satisfaction score of 8.0 versus a satisfaction score of 9.0 for patients with only typical symptoms (P < 0.05). Patients with a satisfaction score < 8.0 had a higher rate of atypical symptoms (75%) than patients with a satisfaction score > or = 8 (50%). CONCLUSION: Laparoscopic Nissen fundoplication controlled typical reflux symptoms very well but atypical symptoms were improved in only approximately 50%. A lower satisfaction score was associated with preoperative atypical symptoms.     

Laparoscopic Nissen fundoplication: two-year comprehensive follow-up of a technique of minimal paraesophageal dissection.

OBJECTIVE: To provide a comprehensive follow-up of 381 patients after laparoscopic Nissen fundoplication (LNF) using a technique of minimal paraesophageal dissection. METHODS: Patients underwent a 24-hour pH recording, esophageal manometry, and symptom score assessment for six symptoms of gastroesophageal reflux disease preoperatively. To date, 260 patients have undergone repeat studies at 6 months and 108 patients at 2 years. RESULTS: LNF was associated with a significant (p < 0.0001) increase in the lower esophageal sphincter (LES) pressure and a significant (p < 0.0001) drop in duration of acid reflux in 24 hours and symptom score 6 and 24 months after surgery when compared to preoperative values. Twelve patients (3%) have experienced recurrence of reflux symptoms, 8 presenting in the first 6 months and 4 by the second year after surgery, but only 1 has required repeat surgery. The incidence of clinical dysphagia was found to be 1.3% of the patient group. CONCLUSIONS: LNF remains an effective antireflux procedure at 2 years. Most recurrences occur early, and there is no significant deterioration in the high-pressure zone at the LES, the percentage reflux in 24 hours, or symptom control between 6 months and 2 years after surgery, suggesting that the long-term results should be satisfactory.     

Comparison of laparoscopic and open Nissen fundoplication 2 years after operationrid=""

BACKGROUND: Laparoscopic operation has replaced the conventional open procedure in the treatment of gastroesophageal reflux disease (GERD) in spite of the fact that long-term results based on controlled clinical trials have been lacking. The objective of this study was to compare outcome, quality of life, and patient satisfaction after laparoscopic and open Nissen fundoplication in a community hospital setting with a 2-year follow-up. METHODS: Forty-two patients with GERD were randomized to either laparoscopic (LNF) or open (ONF) Nissen fundoplication. Outcome evaluation included reflux symptoms, gastrointestinal quality of life (GIQLI), and upper GI endoscopy. RESULTS: Esophagitis was cured among all patients in the LNF group and in 90% of the ONF group. There were two patients (10%) in both groups who had medicine-dependent recurrent reflux together with significant worsening in the GIQLI scores. One patient in the LNF group has been reoperated due to a suture granuloma in the left epigastric port. Two patients in the LNF group needed esophageal dilatation due to persistent dysphagia. GIQLI scores (scale, 0-144) were equally normalized in both groups. Overall, 90% in the LNF and 100% in the ONF group were either satisfied or very satisfied with the operation. There was only one patient (LNF) who would not choose to have the operation again. CONCLUSIONS: Laparoscopic and open Nissen fundoplication seem to be equally effective methods for improving reflux symptoms and quality of life, resulting in a high rate of satisfaction among patients with an intermediate follow-up period of 2 years.     

Videoscopic Heller myotomy with intraoperative endoscopy promotes optimal outcomes.

BACKGROUND AND OBJECTIVES: Minimally invasive surgical techniques are applicable to achalasia, but the optimum approach to intraoperative assessment of adequacy of myotomy remains unestablished. We set out to show that videoscopic Heller myotomy with concurrent endoscopy ensures adequacy of myotomy while limiting postoperative clinically apparent reflux. METHODS: Seventy-eight consecutive patients with achalasia underwent videoscopic Heller myotomy with concomitant endoscopy between 1992 and 1998. Fundoplication was not routinely undertaken. RESULTS: Preoperative symptoms consisted of dysphagia (100%), emesis/regurgitation (68%), heartburn (58%), and postprandial chest pain (49%). Following myotomy, significant improvement (P < 0.0001) was seen in dysphagia (43%), postprandial chest pain (13%), and emesis/regurgitation (9%) at a mean follow-up of 33+/-2.2 months. Mean reflux score (scale 0 to 5) improved from 3.7+/-0.3 to 1.5+/-0.2 (P < 0.0001). Improvement in symptoms was reported in 96% of patients. Fundoplication was used in 8 patients as part of hiatus reconstruction (n = 6) or repair of esophageal perforation (n = 2). CONCLUSIONS: Intraoperative endoscopy during videoscopic Heller myotomy guides the extent and adequacy of myotomy. By utilizing a focused dissection with preservation of the natural antireflux mechanisms around the gastroesophageal junction and limiting the extent of myotomy along the cardia, postoperative reflux symptoms are minimized. We advocate concomitant endoscopy during Heller myotomy to guide myotomy and submit that routine fundoplication is clinically unnecessary.     

Motor function of the esophagus and the lower esophageal sphincter in children who undergo laparoscopic nissen fundoplication

BACKGROUND/PURPOSE: To define the clinical role of laparoscopic Nissen fundoplication (LNF) in children with gastroesophageal reflux (GER), an appropriate understanding of its functional effects is required. The aim of this study was to investigate the motor function of the esophageal body and the lower esophageal sphincter (LES) with special reference to the effects of caloric nutrients in children undergoing LNF. METHODS: Studies were performed in 12 children with GER (age, 6 months to 13 years) before and a month after LNF. Continuous manometric examination was performed with an infusion system using a sleeve sensor for an hour each before and after the administration of apple juice (AAJ; 10 mL/kg). RESULTS: AAJ increased postoperative basal LES pressure from 15 +/- 7 to 20 +/- 6 mm Hg, whereas it decreased the preoperative values from 13 +/- 5 to 10 +/- 4 mm Hg (P < .05). Significant residual pressure was noted at the nadir of swallow-induced LES relaxation after LNF, which was increased by AAJ from 7 +/- 3 to 11 +/- 4 mm Hg. A child with a high nadir LES pressure showed postoperative dysphagia. Significant changes in the patterns of esophageal contractions were not noted after LNF. CONCLUSIONS: Characteristics of the effect of LNF on the LES were a postprandial increase of basal LES pressure and significant residual LES pressure at the nadir of LES relaxation. The motor function of the esophageal body was not affected by LNF.     

Radiofrequency energy delivery to the lower esophageal sphincter (Stretta procedure) does not provide long-term symptom control

The Stretta procedure (radiofrequency energy application to the lower esophageal sphincter) is a unique endoluminal technique for the management of gastroesophageal reflux. This article reports on the long-term effectiveness of the Stretta procedure in patients with significant gastroesophageal reflux disease (GERD) referred to a surgical practice. Patients who underwent Stretta with a minimum of 36 months follow-up were included. Thirty-two patients with an average follow-up of 53 months were included; 19 proceeded to anti-reflux surgery. Those not undergoing surgery showed a significant improvement in their GERD satisfaction from 3.14 to 1.46 (P = .0006) but had significantly lower preprocedure heartburn scores (2.43) than those who proceeded to surgery (3.66, P = .0401). The Stretta procedure was effective in reducing symptoms in 40% of patients. Responders had less severe preoperative heartburn. Radiofrequency energy delivery to the lower esophageal sphincter may be effective in selected patients for the treatment of gastroesophageal reflux.     

Five-year subjective and objective results of laparoscopic and conventional Nissen fundoplication: a randomized trial

OBJECTIVE: The purpose of this prospective study was to compare the subjective and objective outcome of laparoscopic (LNF) and conventional Nissen fundoplication (CNF) up to 5 years after surgery as obtained in a multicenter randomized controlled trial. SUMMARY OF BACKGROUND DATA: LNF is regarded as surgical treatment of first choice for refractory gastroesophageal reflux disease by many surgeons based on several short- and mid-term studies. The long-term efficacy of Nissen fundoplication, however, is still questioned as objective data gathered from prospective studies are lacking. METHODS: From 1997 to 1999, 177 patients were randomized to undergo LNF or CNF. Five years after surgery, all patients were requested to fill in questionnaires and to undergo esophageal manometry and 24-hour pH-metry. RESULTS: A total of 148 patients agreed to participate in the follow-up study: 79 patients after LNF and 69 after CNF. Of these, 97 patients (48 LNF, 49 CNF) consented to undergo esophageal manometry and 24-hour pH-metry. At 5 years follow-up, 20 patients had undergone reoperation: 12 after LNF (15%) and 8 after CNF (12%). There was no difference in subjective outcome, with overall satisfaction rates of 88% and 90%, respectively. Total esophageal acid exposure times (pH < 4) were 2.1% +/- 0.5% and 2.0% +/- 0.6%, respectively (P = 0.21). Antisecretory medication was taken daily in 14% and 16%, respectively (P = 0.29). There was no correlation between medication use and acid exposure and indices of symptom-reflux association (symptom index and symptom association probability). No significant differences between subjective and objective results at 3 to 6 months and results obtained at 5 years after surgery were found. CONCLUSIONS: The effects of LNF and CNF on general state of health and objective reflux control are sustained up to 5 years after surgery and the long-term results of LNF and CNF are comparable. A substantial minority of patients in both groups had a second antireflux operation or took antisecretory drugs, although the use of those medications did not appear to be related to abnormal esophageal acid exposure.     

Gastrointestinal-specific patient-reported outcome instruments differentiate between renal transplant patients with or without GI complications

BACKGROUND: Gastrointestinal (GI) complications are frequently reported postrenal transplant and are often associated with immunosuppressant regimens including mycophenolate mofetil (MMF). This study evaluated the ability of two GI-specific patient-reported outcome (PRO) instruments to differentiate between patients with and without GI complaints. METHODS: Discriminant validity of the Gastrointestinal Symptom Rating Scale (GSRS) and Gastrointestinal Quality of Life Index (GIQLI), as well as two generic instruments (Psychological General Well-Being Index (PGWB) and EQ-5D, was assessed in a multinational study of renal transplant recipients. Patients received therapy that included a calcineurin inhibitor and MMF. Both t-tests and ANOVAs were used to examine differences between patients with and without GI complaints, among levels of severity, and between patients reporting presence/absence of specific GI side effects. RESULTS: Of 96 patients recruited (56% male), 43% had none, 39% mild, 13% moderate, and 6% severe GI symptoms. All GSRS subscales and the GIQLI total and four of the five subscale scores significantly differentiated between patients with/without GI complications (P < .05). The PGWB total score and three subscales, the EQ-5D significantly differentiated between the two groups (P < .05). Only GI-specific instruments discriminated between some severity levels; for example, the GSRS abdominal pain subscale discriminated between patients at all levels of severity (P < .05). The GIQLI total score and symptoms subscale differentiated between patients with no symptoms and those with mild or moderate or severe symptoms (P < .05). CONCLUSIONS: The GSRS and GIQLI differentiated between patients with/without GI side effects and by symptom severity better than did generic instruments, demonstrating excellent discriminant ability in this population.
