Comparison of Laparoscopic 270° Posterior Partial Fundoplication vs Total Fundoplication for the Treatment of Gastroesophageal Reflux Disease

Restoration of the esophagogastric junction competence is critical for effective long-term treatment of gastroesophageal reflux disease. Surgical repair results in such restoration, but mechanical adverse effects seem unavoidable. Minimizing these adverse effects without jeopardizing reflux control is warranted. To determine whether partial fundoplication (PF) or total fundoplication (TF) is superior in laparoscopic antireflux surgery. In this double-blind, randomized clinical trial of 1171 patients scheduled for laparoscopic antireflux surgery at a single university-affiliated center between November 19, 2001, and January 24, 2006, 456 patients were randomized and followed up for 5 years. Data were collected from November 2001 to April 2012, and data were analyzed from April 2012 to September 2018. A 270° posterior PF or a 360° Nissen TF. Esophageal acid exposure at 3 years after surgery. Of the 456 randomized patients, 268 (58.8%) were male, and the mean (SD) age was 49.0 (11.7) years. A total of 229 patients were randomized to PF, and 227 patients were randomized to TF. At 3 years postoperatively, the median (interquartile range) esophageal acid exposure was reduced from 14.6% (9.8-21.9) to 1.8% (0.7-4.4) after PF and from 16.0% (10.4-22.7) to 2.5% (0.8-6.8) after TF (P = .31). Likewise, reflux symptoms were equally and effectively controlled. Early postoperative dysphagia (6 weeks) was common in both groups but then decreased toward normality. A small but statistically significant difference in favor of PF was noted in the mean (SD) scoring of dysphagia for liquids at 6 weeks (PF, 1.6 [0.9]; TF, 1.9 [1.3]; P = .01) and for solid food at 12 months (PF, 1.3 [1.0]; TF, 1.9 [1.4]; P < .001) and 24 months (PF, 1.3 [0.9]; TF, 1.7 [1.2]; P = .001). Quality of life was reduced before surgery but increased to normal values after surgery and remained so over 5-year follow-up, with no difference between the groups. The results from this randomized clinical trial suggest that although PF and TF could be recommended for treatment of gastroesophageal reflux disease, PF might be superior by inducing less dysphagia.

A Large Epiphrenic Esophageal Diverticulum Communicating with the Left Lower Lobe

Epiphrenic diverticula are known to cause a series of complications. We report the case of a 54-year-old woman who was diagnosed with an epiphrenic diverticulum at a regular checkup in November 2006. Ten years later, she presented with massive hematemesis. Imaging studies revealed an epiphrenic diverticulum measuring 7.8 cm in diameter and a large amount of bleeding inside the diverticulum. Computed tomography showed fistula formation between the diverticulum and the left lower lobe of the lung, leading to the development of a pulmonary abscess. Diverticulectomy and 180° posterior partial fundoplication were performed transabdominally. The pulmonary abscess was treated with antibiotics alone. She was discharged 16 days after the operation without any complications over 7 months of follow-up.

Laparoscopic Heller Myotomy for Achalasia: Experience from a Single Referral Tertiary Center.

BACKGROUND Achalasia is the most well known esophageal motility disorder. Laparoscopic Heller myotomy (LHM) is the most effective treatment for achalasia. The aim of this study was to review our results on LHM for achalasia. METHODS In this cross-sectional study all patients undergoing LHM between 2015 and 2017 were studied. The myotomy was followed by an anterior or posterior partial fundoplication. All patients were followed up for at least six months. RESULTS We conducted this prospective study on 36 consecutive patients who underwent LHM over 3 years. The mean age of the patients was 36.64 ± 13.47 years. 30 patients (83.3%) underwent Toupet and 6 patients (16.7%) received Dor fundoplication. 11 patients (30.6%) developed reflux after the procedure. According to the Eckardt Symptom Scoring (ESS), the symptoms improved in 74.2% of the patients and remained unchanged in 25.8% of the patients. Analysis of the ESS, indicated a significant change in regurgitation and retrosternal pain, dysphagia, and weight loss after the surgery (p = 0.001, p = 0.002, p = 0.046, and p = 0.001, respectively). CONCLUSION LHM with anterior or posterior partial fundoplication is safe and achieves a good outcome in the treatment of achalasia, especially in patients who have not responded to other methods while no serious complication was reported despite several prior endoscopic interventions.

Network meta-analysis of surgical management of gastro-oesophageal reflux disease in adults.

Proton pump inhibitors are the mainstay of treatment for gastro-oesophageal reflux disease, but are associated with ongoing costs and side-effects. Antireflux surgery is cost-effective and is preferred by many patients. A total (360o or Nissen) fundoplication is the traditional procedure, but other variations including partial fundoplications are also commonly performed, with the aim of achieving durable reflux control with minimal dysphagia. Many RCTs and some pairwise meta-analyses have compared some of these procedures but there is still uncertainty about which, if any, is superior. Network meta-analysis allows multiple simultaneous comparisons and robust synthesis of the available evidence in these situations. A network meta-analysis comparing all antireflux procedures was performed to identify which has the most favourable outcomes at short-term (3-12 months), medium-term (1-5 years) and long-term (10 years and more than 10 years) follow-up. Article databases were searched systematically for all eligible RCTs. Primary outcomes were quality-of-life measures and dysphagia. Secondary outcomes included reflux symptoms, pH studies and complications. Fifty-one RCTs were included, involving 5357 patients and 14 different treatments. Posterior partial fundoplication ranked best in terms of reflux symptoms, and caused less dysphagia than most other interventions including Nissen fundoplication. This was consistent across all time points and outcome measures. Posterior partial fundoplication provides the best balance of long-term, durable reflux control with less dysphagia, compared with other treatments.

Heller Myotomy: To Wrap or Not to Wrap?

Heller myotomy (HM) is widely recognized as the most effective treatment of achalasia. Although effective in improving dysphagia symptoms, HM is associated with reflux. Over a five-year period, 63 laparoscopic HM were performed. Patients underwent myotomy alone or HM plus reconstitution of the angle of His without any fundoplication, anterior, or posterior partial fundoplication. Two postoperative outcomes were examined: dysphagia and reflux. Twenty-two patients received no fundoplication (34.9%). Forty-one (65.1%) antireflux procedures were performed, including 21 reconstitutions of the angle of His (33.3%), nine (14.3%) anterior fundoplications, and 11 (17.5%) posterior fundoplications. All patients demonstrated preoperative dysphagia. Postoperative dysphagia was present in 23 of 63 (36.5%). Of these, 13 (56.5%) patients had an antireflux procedure, whereas 28 of 40 who had an antireflux procedure (70%) had no postoperative dysphagia (P = 0.28). Thirty-nine of 62 (62.9%) had symptomatic esophageal reflux preoperatively, and postoperative reflux was reported in 22 of 63 (34.9%). Reflux was present in 72.7 per cent of patients who had an antireflux procedure versus 61 per cent of those without the addition of an antireflux procedure (P = 0.415). However, HM independently improved reflux status regardless of whether an antireflux procedure was performed using the exact McNemar's test (P = 0.0014). Although the performance of an antireflux procedure did not appear to alter the reflux status after HM for achalasia, neither was it associated with postoperative dysphagia. More importantly, HM was independently associated with an improvement of reflux symptoms regardless of the type of antireflux procedure performed or whether one was used or not.

Effectiveness of Nissen fundoplication versus anterior and posterior partial fundoplications for treatment of gastro-esophageal reflux disease: a systematic review protocol.

The objective of this review is to determine the relative effectiveness of Nissen fundoplication compared to anterior and posterior partial fundoplication in controlling the symptoms of gastro-esophageal reflux disease and reducing their side effect profile in adults.The specific questions posed by this review are: what is the effectiveness of Nissen fundoplication in comparison to anterior partial fundoplication (90 degree, 120 degree and 180 degree) and posterior 270 degree fundoplication in terms of symptom control of gastro-esophageal reflux disease, and what are the side effects of these surgical interventions?

Laparoscopic Heller Myotomy and Fundoplication: What Is the Evidence?

There is no agreement about the best type of fundoplication to add in patients undergoing laparoscopic Heller myotomy (LHM) for achalasia to reduce the risk of postoperative gastroesophageal reflux. This article reviews the current evidence about the outcomes in achalasia patients undergoing LHM with a partial anterior, a partial posterior, or a total fundoplication. We performed a review of the literature in PubMed/Medline electronic databases, which was evaluated according to the GRADE system. The results of the published randomized controlled trials show with a high level of evidence that the addition of a fundoplication reduces the risk of postoperative abnormal reflux, without impairing the food emptying of the esophagus. LHM with partial fundoplication is considered in most centers worldwide the standard of care for the treatment of patients with achalasia. The current evidence fails to show any significant difference between partial anterior and posterior fundoplication. In the absence of further large randomized controlled trial, the decision of performing an anterior or a posterior wrap is based on the surgeon's experience and preference. The addition of a partial fundoplication to LHM leads to a significantly lower rate of postoperative pathological reflux without impairing the esophageal emptying.

Laparoscopic Antireflux Surgery: Importance of Patient's Selection and Preoperative Workup.

Laparoscopic antireflux surgery (LARS) is an excellent option for patients with symptoms refractory to medical treatment, for patients who have complications secondary to the use of proton pump inhibitors, and for those who do not want to take medications for a long period of time. We hypothesized that (1) LARS has excellent outcomes if a complete preoperative workup and proper patient selection are performed and (2) recurrent symptoms often are not due to failure of the fundoplication to control the pathologic reflux. Every patient referred for antireflux surgery underwent a detailed symptomatic evaluation, barium swallow, esophagogastroduodenoscopy (EGD), high-resolution manometry (HRM), and pH monitoring. A fundoplication was performed in all of them. Data were analyzed to determine outcomes across 8 years. From 2008 to 2016, 176 patients with gastroesophageal reflux disease (GERD) underwent LARS. One hundred and thirty-four patients (76.1%) had a total fundoplication, 31 (17.6%) had an anterior partial fundoplication, and 11 (6.3%) had a posterior partial fundoplication. Thirty-nine patients (22.2%) referred persistent or recurrent symptoms after the procedure and underwent EGD, HRM, and pH monitoring. Abnormal reflux was documented in 5 patients (2.8%). Among these failures, 3 patients had a body mass index (BMI) ≥30 and 2 had ≥35. The results of this study showed that (1) laparoscopic fundoplication is an effective procedure for GERD; (2) patient's BMI can affect the outcome of a fundoplication; and (3) pH monitoring is important to establish if recurrent symptoms are secondary to failure of the operation.

Robot-assisted Heller’s myotomy for achalasia in children

Background: Achalasia is rare in children. Surgical options include open, laparoscopic and robotic approaches. However, Heller’s myotomy remains the treatment of choice. This report describes our experience with robot-assisted Heller’s myotomy in children and presents a review of the literature.Methods: Included in this study are children who underwent robot-assisted Heller’s myotomy for esophageal achalasia via the Da Vinci surgical system between 2004 and 2015 at King Saud University Medical City, Riyadh, Saudi Arabia. The medical records of these patients were reviewed for demographic data, presenting symptoms, diagnostic modalities, operative procedures, complications, outcomes and follow-ups.Results: Six patients were identified. The age of the patients at surgery ranged between 2 and 12 years (mean 7.1 years). The most common presenting symptoms were dysphagia, vomiting and nocturnal cough. Contrast swallow and upper gastrointestinal endoscopy established a diagnosis of esophageal achalasia in all of the patients. Four patients underwent esophageal dilatation 2–5 times before the definitive procedure. All patients underwent successful robot-assisted Heller’s myotomy with concomitant partial posterior fundoplication. The postoperative course was uneventful. Five patients had a complete resolution of the symptoms and one patient improved. The follow-up assessments have been consistent and have ranged from 0.5 to 11 years (mean 4.4 years).Conclusion: Robotic-assisted Heller’s myotomy for esophageal achalasia in children is safe and effective and is a suitable alternative to open and laparoscopic approaches.

Laparoscopic Repair for Failed Antireflux Procedures

Minimally invasive procedures have become common, and more reoperations for failed antireflux procedures are performed laparoscopically. We wanted to study the outcomes of laparoscopic reoperations for reflux. Medical records of all patients who underwent reoperation without esophageal resection after previous antireflux procedures between January 2000 and October 2012 were reviewed. Seventy-five patients were included in this report: 56 (77%) women and 19 (23%) men. Median age was 58 years. The previous operation was laparoscopic antireflux procedures in 65 (87%) patients. The median interval between the last antireflux procedure and laparoscopic reoperation was 42 months. The median body mass index (BMI) was 28.7. All patients were symptomatic. Intraoperative findings included recurrent hiatal hernia in 47 (63%) patients, incompetent fundoplication in 14 (19%) patients, tight fundoplication in 8 (11%) patients, and tight crura in 2 (3%) patients. Laparoscopic Nissen fundoplication was performed in 57 (76%) patients, partial posterior fundoplication was performed in 12 (16%) patients, partial anterior fundoplication was performed in 3 (4%) patients, removal of crural stitches was performed in 2 patients, and a combination of partial posterior fundoplication and removal of crural stiches was performed in 1 patient. Complications occurred in 13 (15%) patients. Improvement in symptoms was observed in 70 (93%) patients in early postoperative follow-up and in 59 (78%) patients in long-term follow-up. Functional results were classified as excellent in 59 (78%) patients, good in 6 (7%) patients, fair in 7 (8%) patients, and poor in 3 (4%) patients. Laparoscopic reoperation for failed antireflux operations is a complex procedure, but it is safe and effective in selected patients. Reoperation after a failed antireflux repair results in excellent or good functional status in a majority of patients, but these results may deteriorate over time.

Toupet versus Dor as a procedure to prevent reflux after cardiomyotomy for achalasia: Results of a randomised clinical trial

BackgroundThe optimal anti-reflux procedure after Heller cardiomyotomy for oesophageal achalasia remains unclear. The most commonly used procedure is the anterior partial fundoplication according to Dor, although during recent years the posterior counterpart (Toupet) has become popular. MethodsPatients with newly diagnosed achalasia and referred for cardiomyotomy were randomised to receive either an anterior or partial posterior fundoplication following a classical cardiomyotomy. The effect of surgery was assessed during the first postoperative year by Eckardt scores, EORTC QLQ-OES18 scores and HRQL questionnaires. Timed barium oesophagogram (TBO) and ambulatory 24-h pH monitoring were performed to determine oesophageal emptying and the degree of reflux control, respectively. ResultsForty-two patients were randomised into Dor (n = 20) and Toupet (n = 22) groups. Eckardt scores improved dramatically with both procedures, but the EORTC QLQ-OES18 (functional scales) scores revealed significantly better relative improvements in the Toupet group compared to the Dor repair (P = 0.044). Corresponding advantages in favour of Toupet were observed postoperatively in the percentage of oesophageal emptying at TBO (P = 0.011 in height and P = 0.018 in area), an effect not observed in the Dor group. There were no other significant differences recorded between the study groups concerning HRQL evaluations and objective assessment of gastro-oesophageal acid reflux. ConclusionsA partial posterior fundoplication after cardiomyotomy seems to achieve more improvement in oesophageal emptying and EORTC QLQ-OES18 functional scale scores than the anterior fundoplication. Otherwise no differences between the two anti-reflux repairs were noted. Trial registration numberClinicalTrials.gov Identifier: NCT01933373.

Randomized controlled trial of laparoscopic anterior 180° partial versus posterior 270° partial fundoplication

Previous trials show good outcomes following anterior and posterior partial versus Nissen fundoplication for gastro-oesophageal reflux. However, it is unclear which partial fundoplication performs best. This study compared anterior 180° versus posterior 270° fundoplication. At three hospitals, patients were randomized to anterior 180° versus posterior 270° partial fundoplication, and clinical outcomes were determined using a structured questionnaire at 3, 6 and 12 months. Heartburn, dysphagia and satisfaction were assessed using 0-10 analoue scales, and adverse outcomes and side effects were determined. Endoscopy, manometry and pH monitoring were performed 6 months after surgery. Forty-seven patients were randomized to anterior (n = 23) versus posterior (n = 24) fundoplication. Clinical outcomes for 93-98% of patients were available at each follow-up point. At 12 months, the mean heartburn score was higher following anterior fundoplication (2.7 versus 0.8, P = 0.045), although differences were not significant at earlier follow-up. Conversely, following posterior fundoplication, patients were less able to belch at 3 (56% versus 16%, P = 0.013) and 6 months (43% versus 9%, P = 0.017). No significant differences were demonstrated for dysphagia. Both groups had high rates of satisfaction with the outcome - 85% versus 86% satisfied at 12 months follow-up. Both partial fundoplications are effective treatments for gastro-oesophageal reflux. Posterior partial fundoplication is associated with less reflux symptoms offset by more side effects.

Postoperative Dysphagia in Laparoscopic Paraesophageal Hernia Repair

Dysphagia following laparoscopic paraesophageal hernia repair is an uncommon but difficult problem that may be due to technical factors. We looked for an association between esophageal angulation after posterior crural repair and postoperative dysphagia. Patients undergoing paraesophageal hiatus hernia repair were identified from a prospectively maintained dedicated database. All patients underwent a standardized laparoscopic repair. Essentially the hernia sac was dissected from the mediastinum, a posterior hiatal repair was carried out with interrupted polyester sutures, and augmented with mesh on lay. A partial posterior fundoplication was then carried out. We used the number of posterior sutures as a proxy for anterior esophageal angulation. Quality-of-life data and dysphagia scores were recorded preoperatively, at 6 weeks postoperatively and 12 months postoperatively using validated instruments. Between November 2004 and September 2010, 114 consecutive patients underwent paraesophageal hiatus hernia repair. There was 1 postoperative death in the series. Median age was 67 years (interquartile range, 59 to 77 y) and 90 (79%) were female. Median hospital stay was 3 days (interquartile range, 2 to 5 y). Follow-up data were available in 87 (76%) of patients at 6 weeks and 94 (82%) of patients at 12 months postoperation. Overall, there was a significant improvement in quality of life that was sustained out to 12 months (P<0.001). Dakkak dysphagia scores were significantly improved postoperatively. Improvement was sustained out to 12 months (P<0.001). Three patients underwent endoscopic esophageal dilation for dysphagia following surgery. There was no significant correlation between the number of posterior sutures used and dysphagia outcome. Specifically there was no association with overall Dakkak scores or change in Dakkak score. Anterior angulation due to posterior hiatal repair does not result in worsening dysphagia, even in patients with large hiatal defects. A posterior repair should therefore remain the standard approach for hiatal closure.

Influence of wrap length on the effectiveness of Nissen and Toupet fundoplications: 5-year results of prospective, randomized study

Long-term results in antireflux surgery may depend on fundoplication type and wrap length. We compared the outcome of two different wrap lengths among the patients undergoing partial or total fundoplications. This study is the next part of a prospective 5-year follow-up assessment. A total of 153 patients were randomized to Nissen or Toupet 1.5- or 3-cm wrap laparoscopic fundoplication. The primary endpoint--treatment failure rate was defined as a recurrent GERD or persistent dysphagia. Intensity of heartburn, dysphagia, gas-bloating, presence of esophagitis were assessed as a secondary outcome at 1-year and 5-year follow-up. At 5-year follow-up, data were collected from 129 (85 %) patients. At 1-year follow-up, 17 (11 %) treatment failures were detected. At the end of the fifth year, the numbers reached 23 (15 %). The failures were more common in the 1.5-cm Toupet (25 %) and the 3-cm Nissen group (18.2 %). The significant difference in failure rates was found between 1.5-cm and 3-cm Toupet groups (P < 0.05). Dysphagia remained low during the follow-up in all of the groups. The prevalence of higher scores of heartburn after 5 years was detected in Nissen 1.5-cm group (20.8 %). The lowest scores were observed in Toupet 3-cm group. Bloating symptoms were more prevalent among Nissen and Toupet 3-cm group patients at 5-year follow-up. At the end of the fifth year, the prevalence of esophagitis was lower in Nissen 1.5-cm (19.3 %) and Toupet 3-cm (13.3 %) groups. The highest prevalence of esophagitis-32.4 %-was found in Toupet 1.5-cm group. Nissen and Toupet fundoplication achieved sufficient control of reflux with success rate of 85 % at 5-year follow-up. There were no significant differences in the postoperative dysphagia, esophagitis, and bloating rates. However, the distribution of treatment failures leads us to conclude that 1.5-cm wrap length is insufficient in cases of posterior partial fundoplication.

Esophageal leiomyomatosis 25 years after myotomy for achalasia

BACKGROUND: Esophageal leiomyomatosis is a rare hamartomatous disorder with cumulative proliferation of the smooth muscle layer of the esophagus causing stenosis and slowly progressive dysphagia. Children and young adults are predominantly affected by this condition. METHODS: Case report. RESULTS: We report about an unusual case of esophageal leiomyomatosis in a 30-year-old female patient with a history of achalasia with Heller myotomy and partial posterior fundoplication as a child. The radiological and endoscopic findings revealed a big circumferential tumor of the gastroesophageal junction with prestenotic dilation. The diagnosis was complicated by the large extension of the tumor and the unusual medical history of the patient mimicking a malign neoplasm. The surgical treatment consisted of esophageal resection with gastric pull-up. To the best of our knowledge, this case report is the first description of the unusual coincidence of an achalasia as a child and an esophageal leiomyomatosis as an adult. CONCLUSIONS: Esophageal leiomyomatosis is an interesting differential diagnosis for all those dealing with patients with diseases of the esophagus.

Laparoscopic Dor versus Toupet fundoplication following Heller myotomy for achalasia: results of a multicenter, prospective, randomized-controlled trial

The type of fundoplication that should be performed in conjunction with Heller myotomy for esophageal achalasia is controversial. We prospectively compared anterior fundoplication (Dor) with partial posterior fundoplication (Toupet) in patients undergoing laparoscopic Heller myotomy. A multicenter, prospective, randomized-controlled trial was initiated to compare Dor versus Toupet fundoplication after laparoscopic Heller myotomy. Outcome measures were symptomatic GERD scores (0-4, five-point Likert scale questionnaire) and 24-h pH testing at 6-12months after surgery. Data are mean±SD. Statistical analysis was by Mann-Whitney U test, Wilcoxon signed rank test, and Freidman's test. Sixty of 85 originally enrolled and randomized patients who underwent 36 Dor and 24 Toupet fundoplications had follow-up data per protocol for analysis. Dor and Toupet groups were similar in age (46.8 vs. 51.7years) and gender (52.8 vs. 62.5% male). pH studies at 6-12months in 43 patients (72%: Dor n=24 and Toupet n=19) showed total DeMeester scores and % time pH<4 were not significant between the two groups. Abnormal acid reflux was present in 10 of 24 Dor group patients (41.7%) and in 4 of 19 Toupet patients (21.0%) (p=0.152). Dysphagia and regurgitation symptom scores improved significantly in both groups compared to preoperative scores. No significant differences in any esophageal symptoms were noted between the two groups preoperatively or at follow-up. SF-36 quality-of-life measures changed significantly from pre- to postoperative for five of ten domains in the Dor group and seven of ten in the Toupet patients (not significant between groups). Laparoscopic Heller myotomy provides significant improvement in dysphagia and regurgitation symptoms in achalasia patients regardless of the type of partial fundoplication. Although a higher percentage of patients in the Dor group had abnormal 24-h pH test results compared to those of patients who underwent Toupet, the differences were not statistically significant.

Total or Posterior Partial Fundoplication in the Treatment of GERD

We lack long-term data (>10 years) on the efficacy of antireflux surgery when evaluated within the framework of randomized clinical trials Hereby we report the outcome of a randomized trial comparing open total (I) and a Toupet posterior partial fundoplication (II) performed between 1983 and 1991. One hundred and thirty-seven patients with gastroesophageal reflux disease and were enrolled into the study. The mean follow up has now reached 18 years. During these years 26% had died and 16% were unable to trace for follow up. Symptom outcomes were assessed by the use of validated self-reporting questionnaires. Long-term control of heartburn and acid regurgitation (reported as no or mild symptoms) were reported by 80% and 82% after a total fundoplication (I) and corresponding figures were 87% and 90% after a partial posterior fundoplication (II), respectively (n.s.).The dysphagia scores were low 4.6 ± 1.3 (SEM) in group I and 3.3 ± 0.9 (SEM) in group II (n.s). The point prevalences of rectal flatulence and gas distension related complaints were of similar magnitude in the 2 groups. Twenty-three percentage of the patients in the total fundoplication group noted some ability to vomit compared with 31% in the partial posterior fundoplication group. Both a total and a partial posterior fundoplication maintain a high level of reflux control after 2 decades of follow up. The previously reported differences in mechanical side effects, in favor of the partial wrap, seemed to disappear over time.

Acid exposure and esophageal motility following laparoscopic fundoplication: A comparative randomized study.

Review: Gastro-esophageal reflux disease is one of the most widely spread diseases allover the world. The principle underlying its surgical management is the creation of a mechanical antireflux barrier between the esophagus and the stomach through the creation of either a total (360 degree), or partial anterior or posterior fundal wraps around the lower esophageal end. The ability of surgery to mechanically control the reflux has been documented. The pathogenesis of gastro-esophageal reflux disease is essentially a motility-related problem with varying contributory elements. The role of different techniques in correcting the underlying motility disorder has been little studied in the randomised literature. Aim: The aim of this study was to compare the ability of the laparoscopic partial posterior and the laparoscopic total fundoplication techniques in objectively controlling the reflux and correcting the underlying esophageal motility disorder in gastro-esophageal reflux patients on the mid-term. Patients and methods: In the period between June 1998 and July 2007, 40 patients considered for antireflux surgery in the department of surgery, Tanta University Hospital, were prospectively recruited and randomised to undergo either laparoscopic total (Nissen) or laparoscopic partial posterior (Toupet) fundoplication. In addition to the clinical follow-up, objective follow up through esophageal manometry, 24-h pH monitoring and upper gastrointestinal endoscopy were performed 24 months after operation and compared to the same data recorded preoperatively. Results: Both the total and the partial posterior fundoplication techniques showed excellent control of heartburn and regurgitation postoperatively. This correlated well with the postoperative endoscopic findings, where both techniques were equally effective in correcting hiatus hernias and healing reflux esophagitis. In the Nissen group, the lower esophageal resting pressure significantly increased postoperatively from a median of 23, to 33 mmHg (p 0.05). Length of the abdominal component was significantly increased postoperatively from a median of 3 to 4 cm and from a median of 2 to 4 cm in the Nissen and Toupet groups respectively (p 0.05). No significant changes were found in the esophageal body contraction amplitude on comparing the pre and postoperative values in both groups (p>0.05). The median total acid exposure time in the Nissen and Toupet groups was significantly reduced from a preoperative 13% to 1% and from 17 % to 0% respectively, with similar reduction in the number of pH proven reflux episodes from a median of 24 to 2 and from 30 to 2 respectively (p < 0.01). The small number of cases with Barrett’s metaplasia in our study made it difficult to draw hard conclusions on the difference between the two surgical techniques in this particular type of patients. Conclusion: The partial posterior and total fundoplication techniques are equally effective in restoring the lower esophageal pressure profile and in objectively controlling the reflux on the mid-term. No changes in the esophageal body contraction amplitude could be found with either technique. No objective advantages could be demonstrated for either technique to support a tailored approach.

Total or Posterior Partial Fundoplication in the Treatment of GERD: Results of a Randomized Trial After 2 Decades of Follow-up

Surgical therapy of gastro-oesophageal reflux disease

Surgery should always be looked upon as complementary to medical therapy in the long-term management of patients with chronic GORD. Available medical therapies are effective and adequate for the control of disease manifestations in the great majority of GORD patients. For patients who have a suboptimal disease control under medical therapy and in those who for various reasons want to discuss an alternative to medical long-term therapy, the following message can be transmitted. Anti reflux surgery is a well-documented effective long-term therapeutic alternative to control GORD. The outcome after surgery is dependent on the experience and quality of the surgeon. These operations are safe but mortality can never attain a zero level and the morbidity has to be realised. Anti reflux surgery has to be centralised within each country. With the aim of optimising the outcome of anti reflux surgery, the surgeon has to perform and master a delicate act of balance on the choice between various fundoplication procedures. On one hand we have the total fundoplication with its proved efficacy regarding reflux control but with it associated somewhat more frequent mechanical side-effects. The posterior partial fundoplication has obvious advantages with less postfundoplication complaints without compromising the level of reflux control and can therefore often be recommended. Most studies present very promising results following anterior partial fundoplications. The spectrum of postfundoplication symptoms can be minimised provided that the surgeon fully comprehend the mechanism of action of these procedures and adhere to technical perfectionism. Evaluation and management of failures after anti reflux surgery have to be centralised within each country.
