Long-term outcomes after laparoscopic antireflux surgery

OBJECTIVES: We studied the long-term outcomes of laparoscopic antireflux surgery (LARS) and the factors that determine it, as neither has been previously well established. METHODS: From September 1993 (start of our program) to September 1999, 441 patients underwent LARS. Preoperative symptoms and the results of esophageal functional studies as well as details of the operation and follow-up were recorded prospectively in our database. In 2004, with the help of a private investigator, we were able to contact 288 (65%). There were no differences in presentation profiles of those patients contacted and those we could not. RESULTS: At a median follow-up of 69 months, individual symptoms, among those who had it preoperatively, were as follows: heartburn (N = 282) improved in 254 (90%) and resolved in 188 (67%); regurgitation (N = 258) improved in 238 (92%) and resolved 199 (70%); dysphagia (N = 123) improved in 96 (78%) and resolved in 76 (62%); cough (N = 119) improved in 82 (69%) and resolved in 48 (40%); and hoarseness (N = 106) improved in 73 (69%) and resolved in 50 (47%). Univariate regression analysis showed that the presence of heartburn (P= 0.02), male gender (P= 0.03), and younger age (P= 0.04) predicted symptom resolution, whereas preoperative dysphagia (P= 0.03), airway manifestations (P= 0.03), bloating (P= 0.04), and defective esophageal motility (P= 0.08) were negative predictive factors. By multivariate analysis, male gender, dysphagia, and age remained significant (P < 0.05). Seven patients (2%) developed a new onset of dysphagia; 32 patients (11%) developed new or increased diarrhea and 27 patients (9%) developed bloating postoperatively. One hundred nineteen patients (41%) were taking some form of antacid medication; 66 (23%) patients were using PPIs and 10 (3%) had undergone reoperation. CONCLUSION: LARS provides effective long-term relief of GERD. Younger patients, men, and those without dysphagia are predictors of superior outcomes.     

Failed antireflux surgery: quality of life and surgical outcome after laparoscopic refundoplication

BACKGROUND AND AIMS: Laparoscopic antireflux surgery has in recent years become the standard procedure for treating severe gastroesophageal reflux disease. Both laparoscopic antireflux surgery and open surgery cause failures which lead to repeat surgery in 3-6% of cases. We evaluated prospectively quality of life and surgical outcome following laparoscopic refundoplication for failed initial antireflux surgery. PATIENTS AND METHODS: We prospectively studied 51 patients undergoing laparoscopic refundoplication for primary failed antireflux surgery, with complete follow-up 1 year after surgery. In 20 cases the initial surgery used the open technique; four had surgery twice previously. In 31 cases primary procedure was performed laparoscopically. Indication for repeat surgery were recurrent reflux ( n=29), dysphagia ( n=12), and a combination of the two ( n=10). Preoperative and postoperative data including 24-h pH monitoring, esophageal manometry, and quality of life (Gastrointestinal Quality of Life Index) were used to assess outcome. RESULTS: Forty-nine procedures (96%) were completed by the laparoscopic technique. Conversion was necessary in two cases with primary open procedure, in one patient because of injury to the gastric wall and in one severe bleeding of the spleen. Postoperatively two patients (3.9%) suffered from dysphagia and required pneumatic dilatation within the first postoperative year. Average operating time was 245 min after an initial open procedure and 80 min after an initial laparoscopic procedure. The lower esophageal sphincter pressure increased significantly from preoperatively 2.8+/-1.8 mmHg at 3 months (12.8+/-4.1 mmHg) and 1 year (12.3+/-3.9 mmHg) after repeat surgery. In these cases the DeMeester score decreased significantly from preoperative 67.9+/-10.3 to 15.5+/-9.4 at 3 months and 13.1+/-8.1 at 1 year after surgery. Mean Gastrointestinal Quality of Life Index increased from 86.7 points preoperatively to 121.6 points at 3 months and 123.8 points at 1 year and was comparable to that of a healthy population (122.6 points). CONCLUSION: Laparoscopic repeat surgery for recurrent or persistent symptoms of gastroesophageal reflux disease is effective and can be performed safely with excellent postoperative results and a significant improvement in patient's quality of life for a follow-up period of 1 year.     

Selection of patients for laparoscopic antireflux surgery

Since the first laparoscopic fundoplication was performed, the frequency of antireflux surgery has increased rapidly with some centers now having an experience of about 1,000 procedures. The question arises whether this increase is due to a change in indications for the surgical treatment of gastrointestinal reflux disease (GERD) despite the simultaneous appearance of powerful antisecretory medications. Adequate knowledge of the pathophysiology of GERD is necessary in order to establish selection criteria for patients suitable for laparoscopic antireflux surgery. In this article, we review the epidemiology and pathophysiology, and provide a rationale for medical and surgical treatment. We also offer an approach to patient selection for antireflux surgery.     

Laparoscopic antireflux surgery for gastroesophageal reflux disease: experience with 668 laparoscopic antireflux procedures

BACKGROUND AND AIMS: In the past decade laparoscopic antireflux surgery has become the standard operation for treating severe gastroesophageal reflux disease. Several studies have been published showing that it can achieve good to excellent results at short- and medium-term follow-up. We present our experience with 668 laparoscopic antireflux procedures. PATIENTS AND METHODS: Between September 1993 and July 2001 we performed 668 laparoscopic antireflux procedures (76% laparoscopic 360 degrees "floppy" Nissen fundoplications in patients with normal esophageal motility, 24% laparoscopic 270 degrees Toupet partial fundoplications in patients with poor esophageal motility or severely disordered peristalsis). Patients with achalasia were excluded from analysis. Preoperative and postoperative data including 24-h pH monitoring, esophageal manometry, and analysis of failure were prospectively reviewed. RESULTS: Overall complication rate was 7.6%. Conversion to open surgery was necessary in five patients (0.8%). Seventy-four laparoscopic redo procedures were performed due to failed primary intervention. There was no death. At a mean follow-up of 4.8 years (range 3-94 months) 24-h pH monitoring and esophageal manometry showed normal values in 93% of patients. CONCLUSION: Laparoscopic antireflux surgery is feasible and effective and can be performed safely without mortality and low morbidity with good to excellent functional and symptomatic results.

Barrett''s esophagus: combined treatment using argon plasma coagulation and laparoscopic antireflux surgery

The treatment of Barrett's esophagus is still controversial. Actually, the only method to prevent the development to cancer is endoscopic surveillance, which ensures good results in terms of long-term survival. An ideal treatment capable of destroying columnar metaplasia, followed by squamous epithelium regeneration could potentially result in a decrease of the incidence of adenocarcinoma. Recently most ablative techniques were used, such as photodynamic therapy, ablation therapy with Nd-YAG laser or argon plasma coagulation and endoscopic mucosal resection. We started a prospective study in January 1998, enrolling 94 patients affected by Barrett's esophagus and candidates for antireflux repair in order to assess the effectiveness and the results of endoscopic coagulation with argon plasma combined with surgery in the treatment of uncomplicated Barrett's esophagus. All patients underwent endoscopic treatment with argon plasma; we observed complete response in 68 patients (72.34%), 27 of them (39.7%) underwent antireflux surgery and the other 41 continued medical therapy. Post-operatively 19 patients (70%) underwent regular surveillance endoscopies and in two cases metaplasia recurred. The final objective of these combined treatments should be the complete eradication of metaplastic mucosa. Our experience was that argon plasma coagulation combined with antireflux surgery or proton pump inhibitor therapy gave satisfactory results, even if follow-up is too short to evaluate the potential evolution of metaplasia to cancer. For this reason, we recommend that this technique should be done only in specialized centres and that these patients continue their endoscopic surveillance program.     

Failed antireflux surgery: surgical outcome of laparoscopic refundoplication in the elderly

BACKGROUND/AIMS: Antireflux surgery has a failure rate between 5 and 20%. Laparoscopic redo-surgery is feasible, but little is known about the surgical outcome in elderly patients. The aim of this prospective study was to evaluate early surgical experience and outcome, including quality of life, after laparoscopic refundoplication in patients older than 65 years. METHODOLOGY: Eleven patients, mean age of 71 years (range: 65-78), underwent laparoscopic redo-surgery. Six patients had the former antireflux procedure performed by the open technique, one having had it twice, one had both laparoscopic and open antireflux procedures, and in 4 the primary intervention was performed laparoscopically. Quality of life was evaluated by using the Gastrointestinal Quality of Life Index. All patients were evaluated prior to surgery, and at 3 months and 12 months after laparoscopic refundoplication, as well as with esophageal manometry and 24-hour pH-monitoring. RESULTS: Redo-procedures were completed laparoscopically in 10 patients. In one patient conversion to an open laparotomy was necessary because of severe bleeding from the spleen. One patient had an injury to the gastric wall, successfully managed laparoscopically. Postoperatively, one patient had moderate dysphagia for a period of two months, another had epigastric pain for the same period. Esophageal manometry and 24-hour pH-monitoring showed normal values in all patients after redo-surgery. Prior to redo-surgery, the mean Gastrointestinal Quality of Life Index was 85.2 points. Three months (mean: 119.8 points) and one year (mean: 119.2 points) after laparoscopic reoperation the general score increased significantly (P < 0.01) and attained the equivalent level of comparable healthy individuals (118.7 points). CONCLUSIONS: Laparoscopic refundoplication in the elderly patient is feasible, safe and an effective treatment after failed antireflux surgery. Older patients with failed antireflux surgery have poor quality of life. Laparoscopic redo-surgery improves quality of life significantly to the level of healthy individuals and normalizes objective outcome criteria without any long-term restrictions in daily life.     

Comorbidity of aerophagia in GERD patients: outcome of laparoscopic antireflux surgery

BACKGROUND: While there is evidence that physiological data correlate poorly with quality-of-life data or patient-perceived symptom severity, most outcome studies of antireflux surgery still refer physiologic criteria. The aim of this prospective study was to establish whether concomitant aerophagia in GERD (gastroesophageal reflux disease) patients might influence the surgical outcome of laparoscopic 'floppy' Nissen fundoplication. METHODS: A total of 112 patients were divided into 2 subgroups: group 1 comprising GERD patients without aerophagia (n = 94; 84%); group 2 of GERD patients with concomitant aerophagia (n = 28; 16%). In all patients, requirements for surgery included an evaluation of symptoms (list of 17 symptoms; patients' grading from no--mild to moderate--severe), quality of life (Gastrointestinal Quality of Life Index: GIQLI), esophagogastroduodenoscopy, esophageal manometry and 24-h pH monitoring. Additionally, we asked for any potential stress relations to GERD symptoms. Surgical outcome was assessed 3 months and 1 year postoperatively. RESULTS: In group 2 patients before surgery, we found a significantly higher percentage with a mild impairment of esophageal motility, with a subjectively and objectively dominant reflux in the upright position, with a lower grading of esophagitis or Barrett esophagus, and with a stronger belief that stress was in any relation to perceived symptoms compared with group 1 patients. Additionally, these patients perceived typical and untypical symptoms more intensively. Factors such as DeMeester score and lower esophageal sphincter pressure did not differ preoperatively, the same as after antireflux surgery. Both groups profit significantly from surgery-a continuous reduction of symptom severity and quality-of-life improvement was found. Group 1 patients showed an improvement in mean GIQLI from 93.4+/-8.3 points preoperatively to 123.1+/-7.3 and 122.9+/-9.0 points 3 months and 1 year postoperatively, whereas group 2 patients demonstrated a lower outcome, from 82.2+/-9.1 points to 112.4+/-8.1 and 116.8+/-7.9 points postoperatively. This lesser improvement is the result of preoperative symptoms such as belching, bloating or flatulence, which many patients had after surgery. In addition, some of the group 2 patients suffered from subjective mild to moderate heartburn or dysphagia, but without any objective correlation. CONCLUSION: GERD patients with concomitant aerophagia demonstrated less symptomatic relief than patients without aerophagia. Moreover, patients with aerophagia showed less quality-of-life improvement after laparoscopic antireflux surgery. There were no significant differences in physiological outcome data between groups. Surgery in GERD patients with symptoms relating to aerophagia should be approached with great care. An additional psychological intervention in these patients might improve surgical outcome.     

Barrett's esophagus control after antireflux surgery.

OBJECTIVE: To study the esophageal motor disorders in patients with Barrett's esophagus after surgical treatment. DESIGN: From January 1993 to September 1998 a prospective study with 25 patients referred to our service for surgical treatment of Barrett's esophagus was conducted. Barium transit, endoscopy, 24-hour monitoring of intraluminal pH and stationary esophageal manometry were carried out in all patients pre- and postoperatively. The results were compared before and after surgery. A p < 0.05 was considered statistically significant. PATIENTS: 18 male (72%) and 7 women (28%). Mean age was 54.20 +/- 13.29 years (range: 25-71 years). The most frequent clinical manifestation was heartburn (92%). A laparotomy procedure was performed in 68% (n = 17) and laparoscopy in 32% (n = 8) of patients. A 360 degrees fundoplication was always performed. RESULTS: 96% of patients presented a defective lower esophageal sphincter. The statistical study demonstrated significant differences after surgery for all pH-metric parameters and lower esophageal sphincter (p < 0.01), except for relaxation (p = 0.465). In the esophageal body, the statistical study only demonstrated significant differences for mean pressure of the peristaltic waves in segment I (p = 0.038) and mean rate of non-transmitted waves in esophageal segment IV-V (p = 0.031). CONCLUSIONS: Antireflux surgery in Barrett's esophagus contributes to the control of gastroesophageal reflux improving esophageal clearing and with significant differences for the mean rate of non-transmitted waves in the distal esophagus.     

Illness behavior and laparoscopic antireflux surgery: tailoring the wrap to suit the patient

Psychological factors are believed to play a role in gastroesophageal reflux disease. It has previously been shown that preoperative illness behavior influences the outcome after laparoscopic Nissen fundoplication. Between August 2001 and June 2004 we considered a partly subjective assessment of illness behavior when selecting patients with gastroesophageal reflux disease for laparoscopic anterior partial (n = 77) or total fundoplication (n = 90). A prospective questionnaire study of illness behavior was also undertaken and the results were correlated with clinical follow up after 12 months. There was a statistically significant difference in age (P < 0.001), primary esophageal peristalsis on manometry (P = 0.037) and two illness behavior category scores related to hypochondriasis (P = 0.041 and P = 0.025) between laparoscopic anterior partial fundoplication and Nissen total fundoplication groups. Despite these differences, there was no significant correlation between preoperative illness behavior score and patient satisfaction in either group. There was a statistically significant negative correlation between the ability to express personal feelings and postoperative heartburn score in those who had a laparoscopic anterior partial fundoplication (P = 0.048). The clinical outcome in both groups was good to excellent in terms of postoperative heartburn and satisfaction scores. A tailored approach in the choice of wrap, taking into account psychological factors preoperatively, is an appropriate strategy for laparoscopic fundoplication.     

Quality of life and surgical outcome after laparoscopic antireflux surgery in the elderly gastroesophageal reflux disease patient

BACKGROUND: Generally, treatment of gastroesophageal reflux disease (GERD) in the elderly follows the same principles as for any adult patient. Currently laparoscopic antireflux surgery (LARS) has not been clearly established in the elderly patient. The aim of this prospective study was to evaluate the surgical outcome including quality of life after LARS in patients older than 65 years. METHODS: Since 1993 more than 500 patients underwent LARS in our institute. A total of 72 patients, older than 65 years, has been treated with laparoscopic 'floppy' Nissen (n = 51) or Toupet (n = 21) fundoplication. The patients included 23 women and 49 men, with a mean age of 71 years (range, 66-79 years). Quality of life was evaluated using the Gastrointestinal Quality of Life Index (GIQLI). The GIQLI was evaluated prior to surgery, and 3 months and 1 year after surgery, with 24-h pH monitoring and esophageal manometry being performed. RESULTS: Intraoperative complications occurred in two patients (both injury of the spleen), successfully managed laparoscopically. Conversion to laparotomy and mortality were 0%. Postoperative complications occurred twice: one patient had a perianal thrombosis; one had an epileptic seizure. Three months and 1 year after surgery 24-h pH monitoring (mean DeMeester score: preoperative, 61.4+/-23.7; 3 months, 8.4+/-6.4; 1 year, 7.8+/-7.2) and esophageal manometry (mean: preoperative, 2.3 = 1.8 mmHg; 3 months, 13.9+/-3.7 mmHg; 1 year, 12.3+/-3.2 mmHg) showed normal values in all patients. GIQLI increased significantly (mean: preoperative, 86+/-9.7 points; 3 months, 120.1+/-8.9 points; 1 year, 119.3+/-10.1 points) after surgery and is comparable to healthy individuals (118.7 points). One patient suffered from severe dysphagia and required dilatation. In two patients laparoscopic refundoplication was necessary 1 year after the initial procedure because of a 'slipping Nissen' and a 'telescope phenomenon'. Three years after LARS (n = 32) data are comparable to I year after surgery. CONCLUSION: As our data show, LARS can be a safe and effective procedure that significantly improves quality of life in the elderly patient suffering from GERD. Age should no longer be a contraindication to LARS.     

Cardiovascular abnormalities accompanying acute spinal cord injury in humans: incidence, time course and severity

The frequency of cardiovascular abnormalities was evaluated in 71 consecutive patients with acute injury to the spinal cord. Persistent bradycardia was universal in all 31 patients with severe cervical cord injury and less common in milder cervical injury (6 of 17) or thoracolumbar injury (3 of 23) (p less than 0.00001). Marked sinus slowing (71 versus 12 versus 4%, respectively, p less than 0.00001), hypotension (68 versus 0 versus 0%, p less than 0.00001), supraventricular arrhythmias (19 versus 6 versus 0%, p = 0.05) and primary cardiac arrest (16 versus 0 versus 0%, p less than 0.05) were significantly more frequent in the severe cervical injury group. The frequency of bradyarrhythmias peaked on day 4 after injury and gradually declined thereafter. All observed abnormalities resolved spontaneously within 2 to 6 weeks. The primary mechanism underlying these observations appears to involve the acute autonomic imbalance created by the disruption of sympathetic pathways located in the cervical cord. Acute severe injury to the cervical spinal cord is regularly accompanied by arrhythmias and hemodynamic abnormalities not found with thoracolumbar cord trauma. These abnormalities are limited to the first 14 days after injury, a period in which life-threatening disturbances must be anticipated.     

Hepatitis E virus infection after haploidentical haematopoietic stem cell transplantation: incidence and clinical course

Hepatitis E virus (HEV) is increasingly found to cause hepatitis in allogeneic haematopoietic stem cell transplantation (HSCT) patients. However, little is known about HEV infection in patients receiving haploidentical HSCT (haplo-HSCT). Here, we retrospectively evaluate the incidence and clinical course of HEV infection in haplo-HSCT patients. From January 2014 to July 2017, 177 patients with unexplained elevated transaminases after receiving haplo-HSCT at Peking University Institute of Haematology were screened for HEV using HEV serology. HEV RNA was assessed in blood samples when HEV-IgG and/or IgM antibodies were positive. Acute HEV infection was identified in 7 patients (3·9%), 1 of whom had developed a chronic HEV infection. The median time from haplo-HSCT to HEV infection was 17·5 (range, 6–55) months. HEV infection was confirmed by the presentation of anti-HEV IgM + anti-HEV IgG (rising) (n = 5) or HEV-RNA + anti-HEV IgM + anti-HEV IgG (n = 2). None of the patients died of HEV infection directly: 2 patients with HEV infection died showing signs of ongoing hepatitis, and 5 patients cleared HEV with a median duration of HEV infection of 1·5 (range, 1·0–5·7) months. In conclusion, HEV infection is a rare but serious complication after haplo-HSCT. We recommend screening of HEV in haplo-HSCT.
