Predictability of dysphagia after laparoscopic nissen fundoplication

Correlation analysis between the changes in plasma ghrelin level and weight loss after sleeve gastrectomy combined with fundoplication

BACKGROUND

Laparoscopic sleeve gastrectomy combined with fundoplication (LSGFD) can significantly control body weight and achieve effective anti-reflux effects. The aim of this study is to investigate the correlation between the alteration in Ghrelin levels and weight loss following SGFD, and to compare Ghrelin levels, weight loss and metabolic improvements between SG and SGFD, with the objective of contributing to the existing body of knowledge on SGFD technique in the management of patients with obesity and gastroesophageal reflux disease (GERD).

METHODS

A retrospective analysis was conducted on the clinical data of 115 obese patients who underwent bariatric surgery between March 2023 and June 2023 at the Department of Minimally Invasivew Surgery, Hernia and Abdominal Wall Surgery, People's Hospital of Xinjiang Uygur Autonomous Region. The subjects were divided into two groups based on surgical methods: sleeve gastrectomy group (SG group, 93 cases) and sleeve gastrectomy combined with fundoplication group (SGFD group, 22 cases). Clinical data, such as ghrelin levels before and after the operation, were compared between the two groups, and the correlation between changes in ghrelin levels and weight loss effectiveness after the operation was analyzed.

RESULTS

Three months after the operation, there was no significant difference in body mass, BMI, EWL%, fasting blood glucose, triglyceride, cholesterol, and uric acid levels between the SG and SGFD groups (P > 0.05). However, the SGFD group exhibited a significant decrease in body weight, BMI, and uric acid levels compared to preoperative levels (P < 0.05), while the decrease in ghrelin levels was not statistically significant (P > 0.05). Logistic regression analysis indicated that ghrelin levels three months after the operation were influential in postoperative weight loss.

CONCLUSION

The reduction of plasma Ghrelin level in patients after SGFD is not as obvious as that in patients after SG, but it can make obese patients get the same good weight loss and metabolic improvement as patients after SG. Ghrelin level at the third month after operation is the influencing factor of postoperative weight loss.

"Comparison of Nissen Rossetti and Floppy Nissen techniques in laparoscopic reflux surgery"

OBJECTIVE

The present study makes a comparative assessment of the Floppy-Nissen (FN) and Nissen-Rossetti fundoplication (NRF) procedures.

METHODS

Included in the study were 80 patients who presented to the General Surgery Department outpatient clinic of Balcalı Hospital of the Cukurova University Faculty of Medicine with gastroesophageal reflux between March 2010 and March 2013 All patients were operated on by the same surgeon using the laparoscopic FN or NRF techniques in a randomized controlled manner. The preoperative and postoperative reflux-specific and nonspecific gastrointestinal symptoms of the patients were compared.

RESULTS

The duration of symptoms had no effect on the level of satisfaction; regurgitation, bloating and heartburn were more common in those with a longer duration of symptoms Of the patients, 92.5% were satisfied with their resulting condition, and 92.5% were inclined toward the surgery. It was further found that there was no difference between the symptoms or satisfaction levels of the patient groups who underwent the FN procedure and those who underwent the NRF procedure, other than those related to the duration of surgery. laparoscopic NF and the NRF fundoplication treatments, aside from the duration of surgery.

CONCLUSION

Our study revealed no significant difference between the laparoscopic NF and the NRF fundoplication treatments, aside from the duration of surgery.KEY MESSAGESThe Nissen-Rossetti technique can be used safely based on the similarity of its outcomes with those of the classical Nissen technique.Despite the documented success of laparoscopic anti-reflux surgery, the absence of studies comparing surgery and medical treatments prevents these discussions from being concluded.Comparison of Nissen Rossetti and Floppy Nissen Techniques in Laparoscopic Reflux Surgery.

Dysphagia after antireflux fundoplication: endoscopic, radiological and manometric evaluation

BACKGROUND

The transient dysphagia after fundoplication is common and most often disappears until six weeks postoperatively.

AIM

Analyze a group of patients who presented late and persistent dysphagia postoperatively.

METHODS

Forty-one patients after Nissen fundoplication, 14 male and 27 female, mean age 48 year, were evaluated based on medical history, esophagogastroduodenoscopy, contrast radiographic examination and esophageal manometry. The results were compared with another 19 asymptomatic individuals.

RESULTS

Contrast radiographic examination of the esophagus revealed in six cases delayed emptying, characterizing that four patients had achalasia and two diffuse spasm of the esophagus. Esophageal manometry showed that maximal expiratory pressure of the lower sphincter ranged from 10 to 38 mmHg and mean respiratory pressure from 14 to 47 mmHg, values similar to controls. Residual pressure ranged from 5 to 31 mmHg, and 17 patients had the same values as the control group.

CONCLUSION

The residual pressure of the lower sphincter was higher and statistically significant in patients with dysphagia compared with those operated without dysphagia. Future studies individualizing and categorizing each motility disorder, employing other techniques of manometry, and the analysis of the residual pressure may contribute to understand of persistent dysphagia in the postoperative fundoplication.

Predictors of clinical outcomes following fundoplication for gastroesophageal reflux disease remain insufficiently defined: a systematic review

OBJECTIVES

Surgical treatment is a therapeutic option for patients with gastroesophageal reflux disease (GERD). It is unclear which patient characteristics influence postoperative success. The purpose of this paper was to review the literature on prognostic factors for patients with GERD treated with fundoplication.

METHODS

We searched Medline and the Cochrane Library Central for studies from 1966 through July 2007. We identified additional studies by reviewing bibliographies of retrieved articles and by consulting experts. We included English language studies that evaluated factors potentially affecting the outcomes after surgical treatments in patients with GERD. We recorded baseline patient characteristics associated with treatment efficacy, details on the study design, comparators, and definitions of outcomes.

RESULTS

We assessed 6,318 abstracts; 53 cohorts and 10 case-control studies met our inclusion criteria. Age, body mass index, sex, esophagitis grade, and dysmotility were generally not associated with treatment outcomes. There were no consistent associations between preoperative response to acid suppression medications, baseline symptoms, baseline acid exposure, degree of lower esophageal sphincter competence, or position of reflux and surgical outcomes. Certain psychological factors might be associated with worse treatment outcomes.

CONCLUSIONS

Although several preoperative predictors of surgical outcomes have been described, the quality and consistency of the data were mixed and the strength of the associations remains unclear. Additional studies with improved methodological designs are needed to better define which patient characteristics are associated with surgical outcomes following fundoplication.

Hospital admissions for respiratory symptoms and failure to thrive before and after Nissen fundoplication

PURPOSE

The purpose of this study is to determine whether Nissen fundoplication decreases hospital admissions for respiratory symptoms and failure to thrive (FTT).

METHODS

A retrospective study using discharge abstract data from Southern California Kaiser Permanente hospitals during the last decade was done. Three hundred forty-two pediatric patients had at least one Nissen fundoplication. Hospital admissions for aspiration and other pneumonia, respiratory distress/apnea, and FTT were determined before and after Nissen fundoplication. Age and associated neurologic disorders were also studied. Statistical analysis was determined by chi(2) analysis, Poisson regression analysis, and relative risk.

RESULTS

The number of patients requiring hospital admission for aspiration and other pneumonia, respiratory distress/apnea, and FTT was similar before and after Nissen fundoplication. The proportion of readmission within 1 year after Nissen fundoplication for aspiration pneumonia was 0.1250 (95% confidence interval [CI], 0.0266-0.3236); other pneumonia, 0.5465 (95% CI, 0.4355-0.6542); respiratory distress/apnea, 0.5039 (95% CI, 0.4145-0.5931); and FTT, 0.5669 (95% CI, 0.4761-0.6545). Associated neurologic disorders independently increased hospital admissions for aspiration and other pneumonia, respiratory distress/apnea, and FTT. Age was inversely related to hospital admissions for respiratory distress and FTT.

CONCLUSION

Nissen fundoplication did not improve hospital admissions for pneumonia, respiratory distress/apnea, and FTT. Associated neurologic disorders increased readmissions for pneumonia, respiratory distress/apnea, and FTT, whereas increasing age decreased readmission for respiratory distress and FTT.

Complications and antireflux medication use after antireflux surgery

BACKGROUND & AIMS

Although antireflux surgery is increasingly common, few studies have assessed the associated complications and health care use after surgery. The aim of this study was to estimate postoperative complications and continued use of antireflux medications and to identify predictors of complications.

METHODS

Through a review of the Department of Veterans Affairs administrative databases, all patients undergoing antireflux surgery from October 1, 1990, through January 29, 2001, were identified. Of 3367 patients identified, 222 were excluded as a result of a diagnosis of esophageal cancer, achalasia, or because there was no diagnosis related to gastroesophageal reflux disease. Medication use was determined for 2406 patients who had a minimum of 1 year of follow-up, including 1 or more outpatient visits at least 6 months after surgery and during the time when national pharmacy records were available.

RESULTS

Dysphagia was recorded in 19.4%, dilation was performed in 6.4%, and a repeat antireflux surgery was performed in 2.3%. The surgical mortality rate was .8%. Prescriptions were dispensed repeatedly for H2 receptor antagonists in 23.8%, proton pump inhibitors in 34.3%, and promotility agents in 9.2% of patients. Overall, 49.8% of patients received at least 3 prescriptions for one of these medications.

CONCLUSIONS

A moderate proportion of patients undergoing antireflux surgeries experienced complications and approximately 50% of patients received multiple prescriptions for antireflux medications at a median of 5 years of follow-up evaluation. Therefore, before surgery is performed, patients considering surgery should be counseled fully about the risk for complications and the likelihood of continued antireflux medication use.

[The outcomes of laparoscopic fundoplication for gastro-oesophageal reflux disease. Long term results]

INTRODUCTION

The aim of this study was to evaluate the long term efficacy of laparoscopic treatment of gastroesophageal reflux disease (GERD).

PATIENT AND METHODS

Between 1(st) January 1992 and 31 December 1996, 161 patients underwent complete or partial laparoscopic fundoplication for a symptomatic GERD. One hundred and twenty three patients were submitted to Nissen-Rossetti fundoplication, 26 patients to Nissen fundoplication and 12 patients to a partial posterior Toupet fundoplication.141 patients were evaluated at 3 months, 2-years and 5-years. Since undergoing the operation, four patients died of unrelated causes, 16 patients could not be contacted for follow up (10%). pH monitoring and oesophageal manometry were performed preoperatively and at 3 months postoperatively. The patients were evaluated 2 and 5-years after surgery by specific phone questionnaire.

RESULTS

There was no mortality, the morbidity rate was 1.2% and the conversion rate was 5%. Incidence of dysphagia 3 months after surgery was 23.4%, and 5-years after 12%; 12% of patients had recurrent symptoms at 5 years.

CONCLUSION

The overall satisfaction rate at 5 years was 91.4%. Nissen-Rossetti fundoplication seems to have better results at 5-years regarding postoperative dysphagia and symptoms recurrence.

Dysphagia after laparoscopic antireflux surgery: a problem of hiatal closure more than a problem of the wrap

BACKGROUND

Postoperative dysphagia after laparoscopic antireflux surgery usually is transient and resolves within weeks after surgery. Persistent dysphagia develops in a small percentage of patients after surgery. There still is debate about whether postoperative dysphagia is caused by the type or placement of the fundic wrap or by mechanical obstruction of the hiatal crura. This study aimed to investigate patients who experienced recurrent or persistent dysphagia after laparoscopic antireflux surgery, and to identify the morphologic reason for this complication.

METHODS

A sample of 50 patients consecutively referred to the authors' unit with recurrent, persistent, or new-onset of dysphagia after laparoscopic antireflux surgery were prospectively reviewed to identify the morphologic cause of postoperative dysphagia. According to their radiologic findings, these patients were divided into three groups: patients with signs of obstruction at or above the gastroesophageal junction suspicious of crural stenosis (group A; n = 18), patients with signs of total or partial migration of the wrap intrathoracically (group B; n = 27), and patients in whom the hiatal closure was radiologically assessed to be correct with a supposed stenosis of the wrap (group C; n = 5). The exact diagnosis of a too tight (group A) or too loose (group B) hiatus in contrast to a too tight wrap (group C) was established during laparoscopic redo surgery (groups B and C) or by x-ray during pneumatic dilation (group A).

RESULTS

For all 18 group A patients, intraoperative x-ray during pneumatic dilation showed the typical signs of hiatal tightness. Of these, 15 were free of symptoms after dilation, and 3 had to undergo laparoscopic redo surgery because of persistent dysphagia. In all these patients, the hiatal closure was narrowing the esophagus. All the group B patients underwent laparoscopic redo surgery because of intrathoracic wrap migration. Intraoperatively, all the patients had an intact fundoplication, which slipped above the diaphragm. Definitely, only in 10% of all 50 patients (group C) presenting with the symptom of dysphagia, was the morphologic reason for the obstruction a problem of the fundic wrap.

CONCLUSIONS

In most patients, postoperative dysphagia is more a problem of hiatal closure than a problem of the fundic wrap.

Gastrointestinal complications of fundoplication

In children with medically refractory gastroesophageal reflux disease (GERD), fundoplication is effective and safe. However, in a subset of patients, gastrointestinal dysfunction occurs postoperatively. Symptoms include chest pain, persistent dysphagia in 5%, gas bloat in 2% to 4%, diarrhea in up to 20%, and dumping syndrome in up to 30%. Symptoms are often nonspecific, arising from recurrent or persistent GERD, anatomic complications such as disrupted or herniated wrap, functional disturbances such as rapid gastric emptying or altered gastric accommodation, or alternative diagnoses such as cyclic vomiting syndrome or food allergy. Detailed investigation, including various combinations of pHmetry, videofluoroscopy, endoscopy, motility studies, and dumping provocation testing, may be required to clarify pathophysiology and guide management.

Functional Problems Following Esophageal Surgery

Functional problems following esophageal surgery for GERD are not infrequent. The majority of patients improve with time. Careful patient selection and attention to surgical technique are key factors in preventing such functional disorders. When anatomic abnormalities related to the fundoplication are identified, reoperation may offer symptom relief. Before embarking on re-fundoplication, a thorough preoperative evaluation of the esophageal physiology is recommended.

Reflux, dysphagia, and gas bloat after laparoscopic fundoplication in patients with incidentally discovered hiatal hernia and in a control group

BACKGROUND

Laparoscopic fundoplication effectively controls reflux symptoms in patients with gastroesophageal reflux disease (GERD). However, symptom relapse and side effects, including dysphagia and gas bloat, may develop after surgery. The aim of the study was to assess these symptoms in patients who underwent laparoscopic fundoplication, as well as in control subjects and patients with hiatal hernia.

METHODS

A standardized, validated questionnaire on reflux, dysphagia, and gas bloat was filled out by 115 patients with a follow-up of 1 to 7 years after laparoscopic fundoplication, as well as by 105 subjects with an incidentally discovered hiatal hernia and 238 control subjects.

RESULTS

Patients who underwent fundoplication had better reflux scores than patients with hiatal hernia ( P = .0001) and similar scores to control subjects ( P = .11). They also had significantly more dysphagia and gas bloat than patients with hiatal hernia and controls ( P < .005 for all comparisons). Gas bloat and dysphagia were more severe in hiatal hernia patients than in controls ( P < 0.005). After fundoplication, the 25% of the patients with the shortest follow-up (1.5 +/- 0.2 years) and the 25% patients with the longest follow-up (5.8 +/- 0.6 years) had similar reflux, dysphagia, and gas bloat scores ( P = .43, .82, and .85, respectively).

CONCLUSION

In patients with severe GERD, laparoscopic fundoplication decreases reflux symptoms to levels found in control subjects. These results appear to be stable over time. However, patients who underwent fundoplication experience more dysphagia and gas bloat than controls and patients with hiatal hernia-symptoms that should be seen as a side effect of the procedure and of GERD itself.

Prospective analysis of convalescence and early pain after uncomplicated laparoscopic fundoplication

BACKGROUND

The aim of this study was to define factors that limit a short period of convalescence and to characterize the pain experienced after laparoscopic fundoplication.

METHODS

This prospective study included 60 consecutive patients who underwent uncomplicated laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease. Patients were recommended to convalesce for 2 days after operation. Duration of convalescence, dysphagia, fatigue, nausea, vomiting and different pain components were registered daily during the first week and on days 10 and 30 after fundoplication.

RESULTS

Thirty-nine patients took a median of 13 (range 3-41) days off work and 60 stayed away from recreational activity for a median of 4 (range 1-22) days. Pain, fatigue and plans made before operation were the main contributors to prolonged convalescence. Some 30-40 per cent of the patients reported moderate or severe dysphagia during the study period. Fatigue scores were significantly increased for 6 days after surgery (P < 0 . 001). Visceral pain dominated over incisional and shoulder pain throughout the study. At day 30, 17 per cent of the patients reported moderate or severe visceral pain.

CONCLUSION

Pain and dysphagia are significant problems after uncomplicated total laparoscopic fundoplication. The time taken off work and away from recreational activity exceeded the recommended 2 days of convalescence, justifying further efforts to optimize early clinical outcome after total laparoscopic fundoplication.

Significant weight loss after laparoscopic Nissen fundoplication

BACKGROUND

Laparoscopic Nissen fundoplication (LNF) has evolved as a gold standard in antireflux surgery. However, the association between body weight and gastroesophageal reflux disease (GERD) is still unclear, and no data are available concerning the effect of fundoplication on body weight. We present the first report elucidating the impact of LNF on body weight in GERD patients with special emphasis on patients' quality of life.

METHODS

From July 2000 to March 2003, LNF was carried out in 213 patients (85 women and 128 men) after thorough preoperative examination including clinical interview with standardized assessment of symptoms and quality of life (QoL), endosocopy, barium swallow, 24-h pH-metry, and manometry. Follow-up investigations were performed 3 and 12 months after LNF obtainable from 209 patients (98.1%) and 154 patients (72.3%), respectively.

RESULTS

The mean body mass index (BMI) decreased significantly after LNF (27.6 +/- 5.6 kg/m(2) before LNF vs 26.0 +/- 3.8 kg/m(2) after LNF, p < 0.001). Twelve months after LNF, neither a tendency toward a renewed increase nor a further decrease in BMI was observable. The average body weight loss was 3.9 kg. BMI reduction was higher in women than in men (p < 0.002), and obese patients lost more weight than lean patients (p < 0.001). There was no association between BMI reduction and dysphagia. Plasma cholesterol and triglyceride levels did not change after LNF. The mean general score of the Gastrointestinal Quality of Life Index markedly improved (90.1 +/- 21.3 before LNF vs 118.0 +/- 16.2 after LNF, p < 0.01), as did the GERD-Health Related Quality of Life Index (21.9 +/- 6.4 before LNF vs 3.5 +/- 2.7 after LNF, p < 0.001). However, there was no association between changes in BMI and QoL.

CONCLUSION

LNF leads to significant and persistent body weight loss.

Effects of manometrically discovered nonspecific motility disorders of the esophagus on the outcomes of antireflux surgery

Nonspecific motility disorders (NMDs) of the esophagus are common manometric findings in patients evaluated for gastroesophageal reflux disease (GERD). However, it is unclear how these disorders affect the outcomes of antireflux surgery. The purpose of this study was to assess symptomatic outcomes of patients with and without NMDs undergoing surgical treatment for GERD. A prospectively gathered database of all patients undergoing antireflux surgery was retrospectively reviewed for preoperative symptoms, symptom severity using the GERD-HRQL (best score 0, worst score 50), esophageal manometry measurements, presence of NMD, type of operation, any transient or permanent postoperative dysphagia, severity of postoperative dysphagia (best score 0, worst score 5), and postoperative symptom severity. A total of 239 patients were studied; 24% had a NMD identified by preoperative esophageal manometry, and 17% of this +NMD group had preoperative dysphagia or atypical chest/epigastric pain compared to 28% of those without a NMD (-NMD group) (P=NS). Preoperative symptom scores were +NMD 33 vs. -NMD 27 (P=0.01). Postoperative symptom scores were +NMD 5 vs. -NMD 3 (P=NS). There were no differences in preoperative or postoperative dysphagia scores. Transient postoperative dysphagia was 15.8% in the +NMD group vs. 16.4% in the -NMD group (P=NS). Postoperative dilation was 0% in the +NMD group vs. 2% in the -NMD group (P=NS). Manometrically discovered NMDs do not appear to affect preoperative symptoms or symptomatic outcomes of patients surgically treated for GERD. These findings my reflect the severity of GERD and may improve with antireflux surgery.

Enteryx

Enteryx (ethylene vinyl alcohol copolymer) was developed as a bulking agent to be injected endoscopically at the lower oesophageal sphincter (LOS) to increase the competency of the gastro-oesophageal barrier in patients suffering from gastro-oesophageal reflux disease (GORD). Preliminary clinical studies have shown that Enteryx implantation is a fast, minimally invasive and safe procedure. In prospective multicentre studies, significant improvement in reflux symptoms, reduction in the use of proton pump inhibitors (PPIs), and objective improvement in acid oesophageal exposure time were observed after 6 months of follow-up. Improvement of GORD symptoms seems to be correlated with the persistence of the implant. Preliminary data suggest a lengthening and an increase in the LOS relaxation pressure as mechanisms of action of this injection technique. Longer follow-up and controlled sham studies are needed to confirm the efficacy of this technique before it can be proposed as a routine alternative to medical or surgical therapies for GORD.

The outcome of laparoscopic antireflux surgery in relation to patients' subjective degree of compliance with former antireflux medication

It is well known that several patient-related factors are able to affect the surgical outcome such as quality of life or symptom relief after laparoscopic antireflux surgery. The aim of the current study was to evaluate and compare surgical outcome up to 1 year after laparoscopic antireflux surgery in relation to patients' subjective degree of compliance with former antireflux medication. Based on a three-level grading of subjective compliance with primary antireflux medication, a total of 140 patients undergoing antireflux surgery were divided into three subgroups: group 1/TC (totally compliant; n = 60), group 2/PC (partially compliant; n = 49); and group 3/NC (noncompliant; n = 31). Gastrointestinal Quality of Life Index (GIQLI), satisfaction with surgery, and the subjective degree of dysphagia as well as traditional outcome data (e.g., DeMeester score, lower esophageal sphincter pressure, side effects) were evaluated in all patients. As a result of surgery, only patients out of group 1/TC (GIQLI, preoperative 86.3 + 9.3 vs. 1 year postoperatively 123.1 + 7.2 points) and group 2/PC (GIQLI, preoperative 94.2 + 8.6 vs. 1 year postoperatively 120.8 + 7.8 points) showed a significant quality of life improvement that remained stable for at least 1 year (P < 0.05-0.01). In contrast, group 3/NC (GIQLI, preoperative 100.2 + 6.1 vs. 1 year postoperatively 117.2 + 9.8 points) patients had no significant quality of life improvement and patient satisfaction with surgery was less good when compared with that of the other groups. In these patients, also the subjective degree of postoperative dysphagia was significantly (P < 0.05-0.001) higher during the 1-year follow-up when compared with patients from group 1/TC or group 2/PC. A total of 42% of group 3/NC patients reported surgical side effects, whereas only 3% from group 1/TC and 10% from group 2/PC stated to be affected by any new symptoms (P < 0.0001). None of group 1/TC or group 2/PC patients suffered from recurrent symptoms or underwent laparoscopic reoperation. Of group 3/NC, a total of four patients (13%) needed any kind of additional intervention in relation to antireflux surgery (reoperation, n = 3; pneumatic dilatation, n = 1). There were no significant differences between the three groups when postoperative values of esophageal manometry and 24-hour pH monitoring were compared. What the current study does show is that the efficacy and the surgical outcome after laparoscopic antireflux surgery partly depends on the subjective degree of patient compliance with primary antireflux medication. Patients with no compliance in relation to former antireflux medication should generally not be refused antireflux surgery. But these patients should be evaluated with great care before surgery and should also be informed that surgical outcome may be affected in several aspects.

Psychological and emotional aspects of gastroesophageal reflux disease

A synergy exists between the psychological and physiological aspects of esophageal and other gastrointestinal symptoms. Based on a biopsychosocial model of disease, several multidisciplinary concepts of interventions in gastrointestinal disorders have been evaluated. The role of psychological factors in gastroesophageal reflux disease (GERD) has been under study. This article reviews psychological and emotional factors influencing GERD symptoms and treatment.

Complications of laparoscopic fundoplication in the elderly

Our objective was to assess the complications of laparoscopic fundoplication in 77 patients older than 70 years of age. The indications for surgery were (1) complications of reflux esophagitis (n = 17), (2) large hiatal hernia (n = 10), (3) asthma and bronchitis (n = 7), (4) the need for other surgery (n = 13), and (5) a patient's desire to discontinue medical treatment that was controlling reflux esophagitis (n = 30). Operative time varied from 34 to 250 minutes (mean [standard deviation], 116 +/- 20). Hospital stay varied from 12 hours to 19 days (mean, 1.2). No patient needed conversion to open operation. Intraoperative complications were observed in 4 patients (5.2%): left pneumothorax in 2, major operative bleeding in 1, and minor spleen lesion in 1. The most common postoperative complications were gas-bloating syndrome and dysphagia. Gastric ulcer was diagnosed in two. Other postoperative complications included acute delirium, acute urinary retention, and acute ischemia of the lower extremity. One patient died of congestive heart failure. It is concluded that laparoscopic fundoplication is an effective procedure for treating geriatric patients with reflux esophagitis and may be performed with low morbidity and mortality rates.

Endoscopic implantation of enteryx for the treatment of gastroesophageal reflux disease: technique, pre-clinical and clinical experience

The implantation of Enteryx polymer in the LES is a fast, minimally invasive procedure with anticipated low procedural risks and limited costs. Preliminary clinical data after 6 months of follow-up show good results in more than 80% of the patients, with objective improvement of acid reflux time. Enteryx is effective in the management of GERD, as evidenced by the ability of GERD patients with a history of use of PPIs and other GERD medications to eliminate or significantly reduce use of these medications. Mechanisms of action of Enteryx implantation suggest a change in distensibility of the LES, allowing a greater competency of the cardia. LES pressure and length might be increased after polymer implantation, and further studies are needed to study the effect of Enteryx on transient relaxations of the LES, which is the prevalent mechanism of reflux in patients with mild GERD. Challenges with this procedure include refining technique to deliver adequate volume in each patient and determining if the ring-shaped implant is needed. In addition to acid reflux, another indication for use of this treatment might be biliary reflux in gastrectomized patients; preliminary data suggest that Enteryx may reduce symptoms and improve bile reflux (J. Devière, unpublished observations, 2002). Further studies are needed to definitively establish the safety of the procedure. This is a major point because gastroenterologists are not dealing with ill patients but primarily with individuals who have a good quality of life while taking PPIs. The other area to investigate is the efficacy of the treatment through a sham-controlled study. Finally, this endoscopic technique will have to be evaluated in terms of cost-effectiveness against medical and surgical therapies.

Austrian experiences of antireflux surgery

BACKGROUND

Antireflux surgery (ARS) is a well established treatment for GERD (gastroesophageal reflux disease). The present study gives an overview of experience in Austria regarding the frequency of open and laparoscopic ARS and how Austrian departments meet the requirements for surgery.

METHODS

A questionnaire was sent to 115 surgical departments in Austria to evaluate in how many institutions antireflux surgery (open and/or laparoscopically) was performed since 1990, and which pre- and postoperative tests were obligatory, optional, or not performed. Units were divided into specialized and nonspecialized.

RESULTS

The laparoscopic approach has gained in importance by about 300% in the past 5 years in the few hospitals performing this procedure. Esophageal manometry and 24-h pH monitoring were rarely done in nonspecialized units, despite the fact that GERD is mainly a functional disorder of the esophagus and stomach. In contrast to the nonspecialized units, the specialized unit performed upper endoscopy, esophageal manometry and 24-h esophageal pH monitoring as obligatory tests.

CONCLUSIONS

ARS, both open and laparoscopic, is not commonly performed in surgical departments in Austria but the frequency has significantly increased in recent years. Laparoscopic ARS is a safe procedure in hospitals performing this frequently. Laparoscopic ARS should only be performed in specialized units with significant experience in gastroesophageal diseases, where functional testing of the esophagus can be done.

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

OBJECTIVE

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

SUMMARY BACKGROUND DATA

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Laparoscopic antireflux surgery with routine mesh-hiatoplasty in the treatment of gastroesophageal reflux disease

One of the most frequent complications after laparoscopic antireflux surgery is intrathoracic migration of the wrap ("slipped" Nissen fundoplication). The most common reasons for this are inadequate closure of the crura or disruption of the crural closure. The aim of this prospective study was to evaluate surgical outcomes in patients who underwent laparoscopic antireflux surgery with simple nonabsorbable polypropylene sutures for hiatal closure in comparison to patients who underwent routine mesh-hiatoplasty. Between 1993 and 1998, a group of 361 patients underwent primary laparoscopic Nissen or Toupet fundoplication with the use of simple nonabsorbable polypropylene sutures for hiatal closure. Since December 1998, in all patients (n = 170) who underwent laparoscopic antireflux surgery, a 1 x 3 cm polypropylene mesh was placed on the crura behind the esophagus to reinforce them. Functional outcome, symptoms of gastroesophageal reflux disease, and postoperative complications such as recurrent hiatal hernia with or without intrathoracic migration of the wrap have been used for assessment of outcomes. In the initial series of 361 patients, postoperative herniation of the wrap occurred in 22 patients (6.1%). Of these 22 patients, 17 of them (4.7%) had to undergo laparoscopic redo surgery. The remaining five patients were free of symptoms. In comparison to these results, in a second group of 170 patients there was only one (0.6%) who had postoperative herniation of the wrap into the chest. There have been no significant differences in objective data such as DeMeester scores or lower esophageal sphincter pressure between the two groups. Postoperative dysphagia was increased during the early period after surgery in patients undergoing mesh-hiatoplasty but resolved without any further treatment within the first year after laparoscopic antireflux surgery. We concluded that routine hiatoplasty with the use of a polypropylene mesh is effective in preventing postoperative herniation of the wrap and leads to a significantly better surgical outcome than closure of the hiatal crura with simple sutures, without any additional long-term side effects.

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.

Analysis of medical compliance in gastro-oesophageal reflux disease patients referred to pre-surgical examination

BACKGROUND

Despite potential of modern pharmacotherapy to control gastro-oesophageal reflux disease and also to improve patients' quality of life, an efficient long-term management always depends on patients compliance with medication.

AIMS

To evaluate and analyse potential aspects of compliance or non-compliance with medical and clinical prescriptions in a selected group of gastro-oesophageal reflux disease patients referred to pre-surgical examination because of persistent or recurrent symptoms.

PATIENTS

A total of 182 gastro-oesophageal reflux disease patients have been divided by patient rating to 3 different subgroups: group 1/TC consisted of patients who subjectively stated to be totally compliant (n=71; 39%); group 2/PC of patients with partial compliance (n=65; 36%), and group 3/NC consisted of patients with non-compliance (n=46; 25%) in relation to the prescriptions of their doctor taking care of their treatment.

METHODS

All patients have been asked for potential aspects of compliance or non-compliance. The following aspects have been analysed: understandable medical prescription, information about gastro-oesophageal reflux disease, subjective severity of gastro-oesophageal reflux disease-related symptoms, severity of disease, side-effects of medication, general rejection of medication, multi-medication, patient age and sex, quality of life, and a specific construct of personality (health locus of control).

RESULTS

Significant differences could be calculated between patients' age and gender showing that female and elderly patients are more compliant with medication. Group 1/TC patients suffered from a significantly longer period of symptoms and received medication for a longer period when compared to the other groups. Quality of life was impaired in all patients but patients in group 3/NC had a significantly better quality of life than patients in group 1/TC. The leading aspects for total compliance were: an understandable medical prescription (95%), high severity of perceived symptoms (76%) and of disease (88%). The major factors in group 2/PC patients have been unclear information about gastro-oesophageal reflux disease (41%), mild severity of perceived symptoms (59%), low severity of disease (30%), and a general rejection of medical treatment (21%). General rejection of drug treatment has been the major factor in group 3/NC patients (80%) which can be viewed in relation to patients' personality

CONCLUSION

Compliance or non-compliance in this selected group of patients depended on several factors such as information, subjective severity of symptoms, severity of disease but, in addition, on patients' personality Therefore, new strategies for compliance with long-term treatment in gastro-oesophageal reflux disease patients should be discussed.

Quality of life and symptomatic outcome three to five years after laparoscopic Toupet fundoplication in gastroesophageal reflux disease patients with impaired esophageal motility

BACKGROUND

Many centers practice a tailored approach to laparoscopic antireflux surgery in attempt to prevent postoperative side effects in gastroesophageal reflux disease (GERD) patients with an impaired esophageal motility. As a result of controversial findings reported in literature no worldwide accepted consensus exists regarding the appropriate indication for this tailored approach. The aim of this prospective study was to evaluate quality of life and symptomatic outcome in selected patients for a follow-up of 3 to 5 years.

METHODS

A total of 155 patients with esophageal dismotility underwent laparoscopic Toupet fundoplication (LTF). Basic requirements for surgery included in all patients a detailed evaluation of symptoms and quality of life (Gastrointestinal Quality of Life Index [GIQLI]), esophagogastroduodenoscopy, 24-hour pH monitoring, and esophageal manometry. Patients were evaluated 6 weeks, 3 months, 1 year, and 3 to 5 years after LTF.

RESULTS

GERD-related symptoms such as heartburn, regurgitation, dysphagia, or chest pain showed a significant improvement (P <0.05 to 0.001) in all gradings immediately after surgery. During the complete follow-up, a total of 4 patients (2.6%) required laparoscopic redo surgery because of recurrent GERD symptoms. Two patients (1.3%) were adequately maintained on short-term proton pump inhibitor therapy because of mild symptoms. All these patients have shown a pathological DeMeester score within the early period after surgery (3 months or 1 year control). Severe and persistent side effects have been present in 7 patients (4.5%), mild to moderate side effects in 11 patients (7.1%). Other side effects have been temporary and resolved spontaneously. GIQLI improved significantly (P <0.05 to 0.01) in all dimensions and persisted for at least 5 years with mean values comparable with healthy individuals.

CONCLUSIONS

LTF is effective, well tolerated, and improves quality of life, improving long-term outcome with an acceptable rate of long-term side effects in GERD patients with moderate to severe esophageal dismotility for a follow-up period of 3 to 5 years.

Laparoscopic antireflux surgery in gastro-oesophageal reflux disease patients with concomitant anxiety disorders

BACKGROUND

Several psychological factors are known to affect the subjective outcome, such as quality of life, after laparoscopic antireflux surgery.

AIM

To evaluate: a. outcome of laparoscopic antireflux surgery in gastro-oesophageal reflux disease patients with concomitant anxiety disorders, b. potential effects of laparoscopic antireflux surgery on psychiatric comorbidities.

PATIENTS AND METHODS

Out of more than 550 patients who underwent laparoscopic antireflux surgery, 21 suffered from additional anxiety disorders. Outcome assessments included traditional data, evaluation of symptoms and side-effects, and quality of life. These data were evaluated before laparoscopic antireflux surgery and 6 weeks, 3 months and 1 year after surgery,

RESULTS

Post-operative lower oesophageal sphincter pressure and DeMeester score were normal in all patients. Subjective severity of anxiety disorders remained unchanged in 13 patients 1 year after surgery. One patient suffered from severe dysphagia and required single dilatation. In this patient, severity and frequency of panic attacks increased for approximately 6 months after laparoscopic antireflux surgery. In 7 patients, total relief of panic symptoms was reported within 3 months post-operatively. Severity of most gastro-oesophageal reflux disease-related symptoms decreased significantly after laparoscopic antireflux surgery, but severity of some symptoms remained stable in patients with continuing anxiety disorders. In all patients, Gastrointestinal Quality of Life Index increased significantly. This improvement was less marked in patients with continuing anxiety disorders. Patients presenting total relief of panic symptoms showed an outcome comparable to normal data.

CONCLUSIONS

Data obtained suggest that patients with concomitant anxiety disorders should not generally be excluded from laparoscopic antireflux surgery but should be selected more carefully. In these patients, surgery significantly improves quality of life and eliminates gastro-oesophageal reflux disease-related symptoms. Some patients demonstrated less symptomatic relief. In contrast, laparoscopic antireflux surgery was able to eliminate panic disorders in one third of our patients.

Practical approaches to dysphagia caused by Esophageal motor disorders

Dysphagia is a common symptom with which patients present. This review focuses primarily on the esophageal motor disorders that result in dysphagia. Following a brief description of the normal swallowing mechanisms and the messengers involved, more specific motor abnormalities are discussed. The importance of achalasia, as the only pathophysiologically defined esophageal motor disorder, is discussed in some detail, including recent developments in pathogenesis and treatment options. Other esophageal spastic disorders are described, with relevant manometric tracings included. In recent years, the importance of gastroesophageal reflux as a primary cause of esophageal dysmotility has been recognized, and this is also discussed. In addition, the motility disturbances that develop after surgical fundoplication are reviewed.

Dysphagia after antireflux surgery

BACKGROUND

Dysphagia is experienced by many patients after antireflux surgery. This literature review examines factors associated with the development, prediction and management of postoperative dysphagia.

METHODS

Published studies examining issues related to dysphagia, gastro-oesophageal reflux and fundoplication were reviewed.

RESULTS

Postoperative dysphagia is usually temporary but proves troublesome for 5--10 per cent of patients. Technical modifications, such as a partial wrap, division of short gastric vessels and method of hiatal closure, have not conclusively reduced its incidence. There is no reliable preoperative test to predict dysphagia.

CONCLUSION

It is uncertain whether postoperative dysphagia arises from patient predilection or is largely a consequence of mechanical changes created by fundoplication. Anatomical errors account for a significant proportion of patients referred for correction of dysphagia but these are uncommon in large single-institution studies. Abnormal manometry cannot predict dysphagia and, on current evidence, 'tailoring' the operation does not prevent its occurrence.

Analysis and surgical treatment of persistent dysphagia after Nissen fundoplication

BACKGROUND

After Nissen fundoplication, troublesome dysphagia develops in 5-10 per cent of patients. The mechanism of dysphagia has not been fully resolved, in spite of a number of studies focusing on oesophageal motility and lower oesophageal sphincter (LOS) dynamics. Tightness and length of the wrap have had considerable attention, without giving a fully satisfactory explanation of the pathophysiological mechanism.

METHODS

Eighteen patients with persistent dysphagia after Nissen fundoplication needing reoperation were studied. Eighteen patients, matched for age and sex, without dysphagia after Nissen fundoplication were used as controls. Reoperation consisted of conversion of a 360 degrees into a 270 degrees wrap. Barium swallow, endoscopy, oesophageal manometry and 24-h pH monitoring were performed before and after (re)operation.

RESULTS

Peristaltic amplitude, velocity and duration of contraction were not significantly influenced by operation. In 16 of 18 patients with dysphagia, LOS relaxation was incomplete and the residual relaxation pressure was significantly higher than that in the group without dysphagia (P < 0.01). No correlation was found between LOS pressure and peristaltic amplitude, nor between LOS pressure and ramp pressure in the distal oesophagus. After reoperation, basal LOS pressure decreased significantly (P < 0.01) and LOS relaxation was complete in all but three patients; residual relaxation pressure decreased (P < 0.01) and was significantly lower than that after uncomplicated Nissen fundoplication. In the latter group, LOS pressure, residual relaxation pressure and ramp pressure increased significantly after operation (P < 0.01).

CONCLUSION

A return to complete LOS relaxation and a decrease in residual relaxation pressure play an important role in resolving dysphagia.
