Failed antireflux surgery: results after reoperation

The Belsey Mark IV procedure in the era of minimally invasive antireflux surgery

BACKGROUND

Different surgical techniques exist in the treatment of giant and complex hiatal hernia. The aim of this study was to identify the role of the Belsey Mark IV (BMIV) antireflux procedure in the era of minimally invasive techniques.

METHODS

A single-center, retrospective cohort study was conducted. All patients who underwent an elective BMIV procedure aged 18 years or older, during a 15-year period (January 1, 2002 until December 31, 2016), were included. Demographics, pre-, per- and postoperative data were analyzed. Three groups were compared. Group A: BMIV as first procedure-group B: BMIV as a second procedure (first redo intervention)-group C: patients who had two or more previous antireflux interventions.

RESULTS

A total of 216 patients were included for analysis (group A n = 127; group B n = 51; group C n = 38). Median follow-up in groups A, B and C was 28, 48 and 56 months, respectively. Patients in group A were older and had a higher American Society of Anesthesiologists score compared to groups B and C. There was zero mortality in all groups. The severe complication rate of 7.9% in group A was higher compared with the 2.9% in group B and 3.9% in group C. Long-term outcome showed true recurrence, defined as both radiographic recurrence as well as associated symptoms, in 9.5% of cases in group A, 24.5% in group B and 44.7% in group C.

CONCLUSIONS

The BMIV procedure is a safe procedure with good results, moreover in the aging and comorbid patient with primary repair of a giant hiatal hernia.

Management of Recurrent Paraesophageal Hernia

Introduction: Recurrent paraesophageal hernias (rPEH) represent a clinical and surgical challenge. Even with a relatively high incidence, most of them are minimally symptomatic, and the need for reoperation is low. For those patients who are candidates for surgery, laparoscopic revision is a feasible and safe technique although there are other treatment options available. Methods: This article provides an overview of the definition, mechanisms of recurrence, epidemiology, clinical presentation, and indications for treatment of rPEH, as well as an overview of the surgical management options and a description of the technical principles of the repair and/or resection. Results: Surgeons should consider multiple factors when deciding the appropriate treatment of patients with rPEH, and all of them require a complete and comprehensive evaluation. The surgical options need to be individualized and include a redo PEH repair and revisional fundoplication, a partial or total gastrectomy with Roux-en-Y reconstruction, or an esophagectomy. There are key steps during the surgical repair that contribute to a successful operation and also auxiliary techniques that can improve postoperative outcomes. After laparoscopic redo most patients have improvement of their symptoms and an acceptable rate of perioperative complications when they are performed by experienced foregut surgeons. In obese patients with rPEH, bariatric surgery can be the best treatment option. Conclusions: Laparoscopic reoperative management should be considered in symptomatic patients who are not controlled with maximal nonoperative therapy, after a thorough work-up and appropriate counseling. In cases with multiple hernia repairs, it is important to consider alternative operations.

LAPAROSCOPIC REDO FUNDOPLICATION ALONE, REDO NISSEN FUNDOPLICATION, OR TOUPET FUNDOPLICATION COMBINED WITH ROUX-EN-Y DISTAL GASTRECTOMY FOR TREATMENT OF FAILED NISSEN FUNDOPLICATION

BACKGROUND:

Laparoscopic Nissen fundoplication fails to control the gastroesophageal reflux in almost 15% of patients, and most of them must be reoperated due to postoperative symptoms. Different surgical options have been suggested.

AIMS:

This study aimed to present the postoperative outcomes of patients submitted to three different procedures: redo laparoscopic Nissen fundoplication alone (Group A), redo laparoscopic Nissen fundoplication combined with distal gastrectomy (Group B), or conversion to laparoscopic Toupet combined with distal gastrectomy with Roux-en-Y gastrojejunostomy (Group C).

METHODS:

This is a prospective study involving 77 patients who were submitted initially to laparoscopic Nissen fundoplication and presented recurrence of gastroesophageal reflux after the operation. They were evaluated before and after the reoperation with clinical questionnaire and objective functional studies. After reestablishing the anatomy of the esophagogastric junction, a surgery was performed. None of the patients were lost during follow-up.

RESULTS:

Persistent symptoms were observed more frequently in Group A or B patients, including wrap stricture, intrathoracic wrap, or twisted fundoplication. In Group C, recurrent symptoms associated with this anatomic alteration were infrequently observed. Incompetent lower esophageal sphincter was confirmed in 57.7% of patients included in Group A, compared to 17.2% after Nissen and distal gastrectomy and 26% after Toupet procedure plus distal gastrectomy. In Group C, despite the high percentage of patients with incompetent lower esophageal sphincter, 8.7% had abnormal acid reflux after surgery.

CONCLUSIONS:

Nissen and Toupet procedures combined with Roux-en-Y distal gastrectomy are safe and effective for the management of failed Nissen fundoplication. However, Toupet technique is preferable for patients suffering from mainly dysphagia and pain.

Outcomes of Laparoscopic Redo Fundoplication in Patients With Failed Antireflux Surgery: A Systematic Review and Meta-analysis

OBJECTIVE

The aim of this meta-analysis was to summarize the current available evidence regarding the surgical outcomes of laparoscopic redo fundoplication (LRF).

SUMMARY OF BACKGROUND DATA

Although antireflux surgery is highly effective, a minority of patients will require a LRF due to recurrent symptoms, mechanical failure, or intolerable side-effects of the primary repair.

METHODS

A systematic electronic search on LRF was conducted in the Medline database and Cochrane Central Register of Controlled Trials. Conversion and postoperative morbidity were used as primary endpoints to determine feasibility and safety. Symptom improvement, QoL improvement, and recurrence rates were used as secondary endpoints to assess efficacy. Heterogeneity across studies was tested with the Chi-square and the proportion of total variation attributable to heterogeneity was estimated by the inconsistency (I2) statistic. A random-effect model was used to generate a pooled proportion with 95% confidence interval (CI) across all studies.

RESULTS

A total of 30 studies and 2,095 LRF were included. The mean age at reoperation was 53.3 years. The weighted pooled proportion of conversion was 6.02% (95% CI, 4.16%-8.91%) and the meta-analytic prevalence of major morbidity was 4.98% (95% CI, 3.31%-6.95%). The mean follow-up period was 25 (6-58) months. The weighted pooled proportion of symptom and QoL improvement was 78.50% (95% CI, 74.71%-82.03%) and 80.65% (95% CI, 75.80%-85.08%), respectively. The meta-analytic prevalence estimate of recurrence across the studies was 10.71% (95% CI, 7.74%-14.10%).

CONCLUSIONS

LRF is a feasible and safe procedure that provides symptom relief and improved QoL to the vast majority of patients. Although heterogeneously assessed, recurrence rates seem to be low. LRF should be considered a valuable treatment modality for patients with failed antireflux surgery.

Patient-related risk factors associated with symptomatic recurrence requiring reoperation in laparoscopic hiatal hernia repair

Background

Recurrent hiatal hernia remains a challenge.

Methods

For initial repairs at our center: patients with 1 repair were compared to those who required reoperation for symptomatic recurrence. Subsequently, patients who had 1 repair at our center were compared to all patients who required reoperation (including initial repair at another center).

Results

There were 401 repairs: 308 primary repairs at our center and 93 reoperations, 287/308 (93%) required 1 repair and 21/308 (7%) required reoperation. Comparing 1 repair versus 21 reoperations, risk factors were abdominoplasty odds ratio = 32.0 (4.1-250.6), P < .001, postoperative lifting/vomiting odds ratio = 11.6 (3.2-42.1), P < .0002, tubal ligation odds ratio = 4.9 (1.1-22.6), P < .04 and height < 160 cm odds ratio = 3.9 (1.1-13.3) P < 0.03. Comparing 287 with 1 repair versus all 93 reoperations, risk factors were post-operative vomiting odds ratio = 22.7 (2.3-218.0), P < .007, abdominoplasty odds ratio = 5.6 (1.0-31.4), P < .0495, post-operative lifting odds ratio = 5.4 (2.2-12.9), P < .0002, age < 52 odds ratio = 3.6 (1.8-7.3), P < .0003, tubal ligation odds ratio = 3.2 (1.2-8.7), P < 0.019 and height < 160 cm odds ratio = 3.0 (1.5-6.1), P < 0.003.

Conclusions

Younger age, shorter stature, heavy lifting or vomiting after surgery, abdominoplasty and tubal ligation are risk factors associated with symptomatic recurrence requiring reoperation.

FAILURE AFTER FUNDOPLICATION: RE-FUNDOPLICATION? IS THERE A ROOM FOR GASTRECTOMY? IN WHICH CLINICAL SCENARIES?

Background:

Re-fundoplication is the most often procedure performed after failed fundoplication, but re-failure is even higher.

Aim:

The objectives are: a) to discuss the results of fundoplication and re-fundoplication in these cases, and b) to analyze in which clinical situation there is a room for gastrectomy after failed fundoplication.

Method:

This experience includes 104 patients submitted to re-fundoplication after failure of the initial operation, 50 cases of long segment Barrett´s esophagus and 60 patients with morbid obesity, comparing the postoperative outcome in terms of clinical, endoscopic, manometric and 24h pH monitoring results.

Results:

In patients with failure after initial fundoplication, redo-fundoplication shows the worst clinical results (symptoms, endoscopic esophagitis, manometry and 24 h pH monitoring). In patients with long segment Barrett´s esophagus, better results were observed after fundoplication plus Roux-en-Y distal gastrectomy and in obese patients similar results regarding symptoms, endoscopic esophagitis and 24h pH monitoring were observed after both fundoplication plus distal gastrectomy or laparoscopic resectional gastric bypass, while regarding manometry, normal LES pressure was observed only after fundoplication plus distal gastrectomy.

Conclusion:

Distal gastrectomy is recommended for patients with failure after initial fundoplication, patients with long segment Barrett´s esophagus and obese patients with gastroesophageal reflux disease and Barrett´s esophagus. Despite its higher morbidity, this procedure represents an important addition to the surgical armamentarium.

Third-time ("redo-redo") anti-reflux surgery: patient-reported outcomes after a thoracoabdominal approach

BACKGROUND

Approximately 3-6% of patients undergoing anti-reflux surgery require "redo" surgery for persistent gastroesophageal reflux disease (GERD). Further surgery for patients with two failed prior anti-reflux operations is controversial due to the morbidity of reoperation and poor outcomes. We examined our experience with surgical revision of patients with at least two failed anti-reflux operations.

METHODS

Adults undergoing at least a second-time revision anti-reflux surgery between 1999 and 2017 were eligible. The primary outcomes were general and disease-specific quality-of-life (QoL) scores determined by Short-Form-36 (SF36) and GERD-Health-Related QoL (GERD-HRQL) instruments, respectively. Secondary outcomes included perioperative morbidity and mortality.

RESULTS

Eighteen patients undergoing redo-redo surgery (13 with 2 prior operations, 5 with 3 prior operations) were followed for a median of 6 years [IQR 3, 12]. Sixteen patients (89%) underwent open revisions (14 thoracoabdominal, 2 laparotomy) and two patients had laparoscopic revisions. Indications for surgery included reflux (10 patients), regurgitation (5 patients), and dysphagia (3 patients). Intraoperative findings were mediastinal wrap herniation (9 patients), misplaced wrap (2 patients), mesh erosion (1 patient), or scarring/stricture (6 patients). Procedures performed included Collis gastroplasty + fundoplication (6 patients), redo fundoplication (5 patients), esophagogastrectomy (4 patients), and primary hiatal closure (3 patients). There were no deaths and 13/18 patients (72%) had no postoperative complications. Ten patients completed QoL surveys; 8 reported resolution of reflux, 6 reported resolution of regurgitation, while 4 remained on proton-pump inhibitors (PPI). Mean SF36 scores (± standard deviation) in the study cohort in the eight QoL domains were as follows: physical functioning (79.5 [± 19.9]), physical role limitations (52.5 [± 46.3]), emotional role limitations (83.3 [± 36.1]), vitality (60.0 [± 22.7]), emotional well-being (88.4 [± 8.7]), social functioning (75.2 [± 31.0]), pain (66.2 [± 30.9]), and general health (55.0 [± 39.0]).

CONCLUSION

An open thoracoabdominal approach in appropriately selected patients needing third-time anti-reflux surgery carries low morbidity and provides excellent results as reflected in QoL scores.

One More Time: Redo Paraesophageal Hernia Repair Results in Safe, Durable Outcomes Compared with Primary Repairs

The incidence and causes of failed paraesophageal hernia repairs (PEHR) remain poorly understood. Our study aimed to evaluate long-term clinical outcomes after reoperative fundoplication as compared with initial PEHR. A prospectively maintained institutional hernia-specific database was queried for PEHR between 2008 and 2017. Patients with prior history of PEHR were categorized as “redo” paraesophageal hernia (RPEH). Primary outcomes included postoperative morbidity, mortality, symptom resolution, and hernia recurrence. A total of 402 patients underwent minimally invasive PEHR (Initial PEH = 305, RPEH = 97). Redo PEHR had more prevalent preoperative nausea/vomiting (50.6% vs 34.1%, P < 0.007) and weight loss (24.1% vs 13.5%, P < 0.02). RPEH had had longer mean operative time (256.4 ± 91.2 vs 190.3 ± 59.9 minutes, P < 0.0001) and higher rate of conversion to open (10.3% vs 0.67%, P < 0.0001); however, no difference was noted in postoperative complications, hernia recurrence, or mortality between cohorts. Laparoscopic revision of prior PEHR in symptomatic patients can be safely performed with favorable outcomes compared with initial PEHR. Despite redo procedures seeming to be more technically demanding (as noted by longer operative time and higher conversion rates), outcomes are similar and overall resolution of symptoms is achieved in most patients.

Esophageal hiatal hernia: risk, diagnosis and management

Esophageal hiatal hernia involves abnormal abdominal entry into thoracic cavity. It is classified based on orientation between esophageal junction and diaphragm. Sliding hiatal hernia (Type-I) comprises the most frequent category, emanating from right crus of diaphragm. Type-II esophageal hernia engages both left and right muscular crura. Type-III and IV additionally include the left crus. Age and increased body mass index are key risk factors, and congenital skeletal aberrations trigger pathogenesis through intestinal malrotations. Familiar manifestations include gastric reflux, nausea, bloating, chest and epigastric discomfort, pharyngeal and esophageal expulsion and dysphagia. Weight loss and colorectal bleeding are severe symptoms. Areas covered: This review summarizes updated evidence of pathophysiology, risk factors, diagnosis and management of hiatal hernias. Laparoscopy and oesophagectomy procedures have been discussed as surgical procedures. Expert commentary: Endoscopy identifies untreatable gastric reflux; radiology is better for pre-operative assessments; manometry measures esophageal peristalsis, and CT scanning detects gastric volvulus and associated organ ruptures. Gastric reflux disease is mitigated using antacids and proton pump and histamine-2-receptor blockers. Severe abdominal penetration into chest cavity demands surgical approaches. Hence, esophagectomy has chances of post-operative morbidity, while minimally invasive laparoscopy entails fewer postoperative difficulties and better visualization of hernia and related vascular damages.

Primary and Redo Antireflux Surgery: Outcomes and Lessons Learned

INTRODUCTION

Some patients require one or more reoperative interventions after undergoing primary antireflux surgery (ARS). We compared outcomes after primary and reoperative ARS.

METHODS

We queried a prospectively maintained database to identify patients who underwent ARS from September 23, 2003 to May 28, 2016. Patients were categorized into four groups: A (primary ARS), B (first reoperative ARS), C (second reoperative ARS), or D (≥ third reoperative ARS). Patients completed follow-up foregut symptom surveys and satisfaction questionnaires at regular intervals.

RESULTS

In total, 940 patients were studied (A: n = 545, B: n = 302, C: n = 80, D: n = 13). Age, sex, and BMI were comparable across groups. Heartburn was the most common preoperative symptom in A, whereas dysphagia was more common in B-D. Open approach, mean operative time, and mean blood loss increased from A to D (P < 0.05), as did need for Roux-en-Y reconstruction. Vagal injury (2-19-33-54%; P < 0.05), visceral perforation (2-20-36-23%; P < 0.05), postoperative leak (0.2-2-6-8%; P < 0.05 A vs. all), and morbidity (2-10-14-39%; P < 0.05) also increased from A to D. At mean follow-up of 36 months, the proportion of patients who reported no significant symptoms, excellent satisfaction, and likeliness to recommend this surgery to a friend progressively declined with each successive reintervention (P < 0.05).

CONCLUSIONS

Complications and patient-reported outcomes worsen with each reoperative ARS.

A modification of Nissen fundoplication improves patients' outcome and may reduce procedure-related failure rate

BACKGROUND

Laparoscopic anti-reflux surgery has a failure rate of 10-20%. We aimed to investigate whether a modification of Nissen fundoplication (MNF) may improve patients' outcome and reduce failure rate.

MATERIALS & METHODS

We prospectively compared 40 consecutive patients with gastroesophageal reflux disease who underwent anti-reflux surgery: 20 Nissen fundoplication (NF) and 20 the MNF approach. Eight cases in the MNF group needed redo surgery. The MNF consisted in suturing the esophagus to the diaphragmatic crura on each side by means of 4 non-absorbable stitches and in fixing the upper stitch of the valve to diaphragm. In case of clearly weak crura, a reinforcement with Ultrapro mesh was used. All patients were assessed before and after surgery using validated symptoms and quality of life (GERD-HRQL) questionnaires, manometry and 24-h impedance-pH monitoring, endoscopy and barium-swallow.

RESULTS

Mortality and postoperative complications were nil. At a median follow-up of 36 months, no significant differences emerged between the MNF and NF group in terms of symptoms, GERD-HRQL scores, manometric findings, and impedance-pH features. Dysphagia was not reported by the MNF group, while it was quite common (20% vs.0%, p = ns) in the NF group. Anti-reflux surgery was successful in all patients in the MNF group, whereas two patients in the NF group presented a slipped wrap and one recurrent reflux; two of these cases required redo-surgery (10% vs. 0%, p = ns).

CONCLUSIONS

Our preliminary data demonstrated that the MNF is a safe and effective procedure. Further, it seems to reduce the failure rate associated to the surgical procedure.

Pre-operative clinical and instrumental factors as antireflux surgery outcome predictors

Gastroesophageal reflux disease (GERD) is nowadays a highly prevalent, chronic condition, with 10% to 30% of Western populations affected by weekly symptoms. Many patients with mild reflux symptoms are treated adequately with lifestyle modifications, dietary changes, and low-dose proton pump inhibitors (PPIs). For those with refractory GERD poorly controlled with daily PPIs, numerous treatment options exist. Fundoplication is currently the most commonly performed antireflux operation for management of GERD. Outcomes described in current literature following laparoscopic fundoplication indicate that it is highly effective for treatment of GERD; early clinical studies demonstrate relief of symptoms in approximately 85%-90% of patients. However it is still unclear which factors, clinical or instrumental, are able to predict a good outcome after surgery. Virtually all demographic, esophagogastric junction anatomic conditions, as well as instrumental (such as presence of esophagitis at endoscopy, or motility patterns determined by esophageal high resolution manometry or reflux patterns determined by means of pH/impedance-pH monitoring) and clinical features (such as typical or atypical symptoms presence) of patients undergoing laparoscopic fundoplication for GERD can be factors associated with symptomatic relief. With this in mind, we sought to review studies that identified the factors that predict outcome after laparoscopic total fundoplication.

Laparoscopic repair for failed antireflux procedures

BACKGROUND

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.

METHODS

Medical records of all patients who underwent reoperation without esophageal resection after previous antireflux procedures between January 2000 and October 2012 were reviewed.

RESULTS

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.

CONCLUSIONS

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.

[The Mexican consensus on gastroesophageal reflux disease. Part II]

OBJECTIVE

To update the themes of endoscopic and surgical treatment of Gastroesophageal Reflux Disease (GERD) from the Mexican Consensus published in 2002.

METHODS

Part I of the 2011 Consensus dealt with the general concepts, diagnosis, and medical treatment of this disease. Part II covers the topics of the endoscopic and surgical treatment of GERD. In this second part, an expert in endoscopy and an expert in GERD surgery, along with the three general coordinators of the consensus, carried out an extensive bibliographic review using the Embase, Cochrane, and Medline databases. Statements referring to the main aspects of endoscopic and surgical treatment of this disease were elaborated and submitted to specialists for their consideration and vote, utilizing the modified Delphi method. The statements were accepted into the consensus if the level of agreement was 67% or higher.

RESULTS

Twenty-five statements corresponding to the endoscopic and surgical treatment of GERD resulted from the voting process, and they are presented herein as Part II of the consensus. The majority of the statements had an average level of agreement approaching 90%.

CONCLUSION

Currently, endoscopic treatment of GERD should not be regarded as an option, given that the clinical results at 3 and 5 years have not demonstrated durability or sustained symptom remission. The surgical indications for GERD are well established; only those patients meeting the full criteria should be candidates and their surgery should be performed by experts.

The Belsey Mark IV: an operation with an enduring role in the management of complicated hiatal hernia

BACKGROUND

The Belsey Mark IV operation has been used for the management of hiatal hernia for over 40 years, but with the introduction of laparoscopic techniques its role has become questionable. To determine the current role of this procedure we present a contemporary series of patients.

METHODS

We reviewed fifteen consecutive patients, mean age of 63 years, who underwent a Belsey Mark IV fundoplication for gastroesophageal reflux in the presence of a hiatal hernia in our Department from January 2005 to March 2011. Indications for the thoracic approach included paraesophageal hernias, recurrent hiatal hernias and previous upper abdominal surgery.

RESULTS

There was no operative mortality. Immediate postoperative morbidity included 1 case of bleeding, 1 case of pneumonia and 1 case of atrial fibrillation. The mean length of stay was 5.9 days. After a mean follow-up time of 49 months, all patients reported total or partial alleviation of their symptoms. No hernia recurrence was detected during barium swallow examination.

CONCLUSIONS

The Belsey approach is a procedure that can be useful as an alternative in selected cases when there are co-morbidities complicating the transabdominal (laparoscopic) approach.

Incidence and predisponent factors for the migration of the fundoplication by Nissen-Rossetti technique in the surgical treatment of GERD

BACKGROUND

Gastroesophageal reflux is the gastrointestinal tract disease most frequently find nowadays. The Nissen-Rossetti fundoplication is widely used for the surgical treatment, and intrathoracic migration of the valve is the most frequent complication.

AIM

To assess the incidence of the fundoplication and its risk factors.

METHODS

Were analyzed retrospectively medical records of 207 patients undergoing laparoscopic fundoplication by the Nissen-Rossetti technique for the treatment of reflux disease. The variables analyzed were: sex, age, esophagitis grade, size of the herniation, enlargement of the cardia and esophageal shortening. For quantitative variables, was considered the Student's t test. For the nominal, was considered the chi-square or Fisher's exact test. P values ​​<0.05 were considered statistically significant.

RESULTS

Of the total, 135 were women (65.22%) and 72 men (34.78%) with mean age of 47.43 years. The size of the hernia varied between 2 and 6 cm. Two hundred patients had esophagitis (96.62%) and 113 (56.50%) grade I, 75 grade II (37.50%) and 12 grade III or IV (6%). Enlargement of the cardia and Barrett's esophagus were seen in 153 (73.91%) and 13 (6.28%) cases, respectively. One patient had esophageal shortening. Among women, 33 (24.4%) showed migration and among men, only six (8.3%) (p = 0.005). The average age of patients with and without migration was 54.03 and 45.89 years, respectively (p = 0.001).

CONCLUSION

The incidence of the fundoplication migration was 18.8%. The gender (female) and higher age influence the probability of migration. The degree of esophagitis, size of hernia and enlargement of the cardia were not risk factors for intrathoracic migration of the fundoplication.

Update on fundoplication for the treatment of GERD

Rudolph Nissen firstly implemented the idea of surgical treatment of gastroesophageal reflux more than 55 years ago. Today, laparoscopic fundoplication has become the surgical "golden standard" for the treatment of GERD. However, the initial enthusiasm and increasing number of performed procedures in the early 1990s declined dramatically between 2000 and 2006. Despite its excellent outcome, laparoscopic fundoplication is only offered to a minority of patients who are suffering from GERD. In this article we review the current indications for antireflux surgery, technical and intraoperative aspects of fundoplication, perioperative complications as well as short and long-term outcome. The focus is on the laparoscopic approach as the current surgical procedure of choice.

Transthoracic repair of slipped Nissen fundoplications: technique and results

BACKGROUND

Laparoscopic Nissen fundoplication is a common operation performed for reflux disease, generally with good results. A small percentage of patients experience transthoracic migration of the wrap, causing recurrent symptoms and eventually requiring transthoracic repair.

METHODS

A retrospective chart review was performed for all patients who underwent a transthoracic repair of a slipped Nissen fundoplication at our institution from 2006 to 2010. Data included demographics, previous antireflux operations, symptoms at presentation, findings at operation, and overall outcome.

RESULTS

Sixteen patients with a mean age of 61 years (range, 51-76 years) were identified who fit inclusion criteria. The most common presenting symptom was pain. Intraoperative findings included hiatal breakdown in all patients, shortened esophagus in 10 (62%) patients, and foreign body/mesh in 4 (25%) patients. Nine (56%) patients underwent a Collis gastroplasty along with a Nissen fundoplication. Nissen fundoplication alone was performed in 6 (38%) patients and a Belsey fundoplication with a Collis gastroplasty was performed in 1 (6%) patient. Minor complications occurred in 4 (25%) patients and major complications were seen in 2 (13%) patients. The median length of stay was 9 days (range, 6-30 days). There were no postoperative deaths. Overall, 12 (75%) of the patients were judged to have a good outcome, 3 (19%) a fair outcome, and 1 (6%) a poor outcome over a median 9-month follow-up.

CONCLUSIONS

Transthoracic repair in patients who have had transthoracic migration of a previous Nissen fundoplication has acceptable surgical outcome and affords symptomatic relief to the majority of patients.

Efficacy and feasibility of laparoscopic redo fundoplication

BACKGROUND

Nearly 15% of patients who undergo anti-reflux surgery report recurrent symptoms on long-term follow-up and may be candidates for redo anti-reflux surgery (redo-ARS). In the last 10 years, several studies have evaluated the feasibility and short-term results of redo-ARS. The purpose of the present study was to critically review our experience with 102 redo fundoplications with short- to medium-term follow-up and special emphasis on subjective outcomes for redo-ARS.

METHODS

A retrospective chart analysis was done on consecutive 102 redo fundoplications performed between December 2003 and March 2008. The patients were divided into two groups, the open group (group A) and the laparoscopic (group B). Subjective symptom analysis was performed on an annual basis using a standard questionnaire.

RESULTS

There was no significant difference in mean age, body mass index (BMI), or time since first surgery between the two groups. Significant differences were noted between operative time, estimated blood loss, and median hospital stay between the two groups. A total of 16 patients were found to have short esophagus and underwent Collis gastroplasty. Complications included 11 hollow viscus injuries seen in group A and 13 such injuries in group B. There was significant improvement in all symptom scores in the two groups, along with a significant decrease in the use of acid suppression therapy. In the open group 58% of patients rated their satisfaction as excellent compared to 90% in the laparoscopic group.

CONCLUSIONS

This study clearly establishes the safety and efficacy of redo laparoscopic anti-reflux surgery with excellent outcomes after short- to medium-term follow-up.

Re-operation for failed gastro-esophageal fundoplication. What results to expect?

The aim of this study is to evaluate short and medium term results of re-operation for failed fundoplication in a retrospective monocentric cohort of 47 patients.

PATIENTS AND METHODS

Between 1995 and 2011, 595 patients underwent a laparoscopic primary fundoplication (PFP) for gastroesophageal reflux disease (GERD). During the same period, 47 patients required a re-operative fundoplication (RFP). In 11 patients, the original wrap had herniated into the thorax. All these revisions consisted of a complete takedown of the original wrap before constructing a tension-free wrap using a standardized technique. Patients with a follow-up of at least 2 years were matched to patients who had been operated only once to assess satisfaction and quality of life.

RESULTS

Short term: All patients were operated by laparoscopy with no conversion. There was no mortality. Two postoperative complications necessitating re-operation were observed (morbidity 4.3%): one complete aphagia and one gastric perforation. Long term: 29 re-operated patients with a follow-up of at least 2 years (mean: 4,5 years) (Group RFP) were compared to a matched group of 29 patients operated only once (Group PFP). These groups were comparable in age, sex ratio, BMI and follow-up. In both groups, all patients were operated by laparoscopy without conversion. Morbidity was 3.5% in the RFP group, none in the PFP group. There was no mortality in either group. The length of stay and operative time were significantly higher in the RFP group (4.6 vs. 2.6 days, p<0.05). Two RFP patients (5%) required re-operation at three and seven months vs. none in the PFP group. The long-term satisfaction was comparable in the two groups (78% vs. 85%, p=NS). Quality of life assessed by the GIQLI was significantly better in the PFP group (104 vs. 84, p<0.05).

CONCLUSION

Re-do fundoplication is a safe procedure and is feasible by laparoscopy. In the long-term, patient satisfaction is comparable to primary intervention with, however, a slightly poorer quality of life.

Reoperative antireflux surgery for failed fundoplication: an analysis of outcomes in 275 patients

BACKGROUND

With an increase in the performance of laparoscopic antireflux procedures, more patients with a failed primary antireflux operation are being referred to thoracic surgeons for complex redo procedures. The objective of this study was to evaluate our results of redo antireflux surgery.

METHODS

We conducted a retrospective review of patients who underwent redo surgery for failed fundoplication. The primary endpoint was failure of the redo operation; other endpoints included gastroesophageal reflux disease-health-related quality of life (HRQOL) after redo fundoplication.

RESULTS

A total of 275 patients (median age, 52 years; range, 17 to 88 years; men 82, women 193) underwent redo antireflux surgery. The most common pattern of failure of the initial operation was transmediastinal migration-recurrent hernia in 177 patients (64%). Redo surgery included Nissen fundoplication in 200 (73%), Collis gastroplasty in 119 (43%), and partial fundoplication in 41 (15%). There was no perioperative mortality. At a median follow-up of 39.6 months, 31 patients (11.2%) had a failure of the redo surgery, requiring reoperation. The two-year estimated probability of freedom from failure was 93% (95% confidence interval 89% to 96%). The HRQOL scores, available for 186 patients, were excellent to satisfactory in 85.5%, and poor in 14.5%.

CONCLUSIONS

Redo antireflux surgery can be performed safely in experienced centers with outcomes that are similar to published open results. Complete takedown and reestablishment of the normal anatomy, recognition of a short esophagus, and proper placement of the wrap are essential components of the procedure. Thoracic surgeons with significant laparoscopic and open esophageal surgical experience can perform minimally invasive, complex redo esophageal antireflux procedures safely with good results.

Laparoscopic conversion from Nissen to partial fundoplication for refractory dysphagia

Laparoscopic Nissen fundoplication is effective for treating gastroesophageal reflux and is usually well tolerated. Some patients, however, experience postoperative dysphagia refractory to conservative measures. We report our experience and operative technique for laparoscopic conversion of previous laparoscopic Nissen fundoplication to partial fundoplication to relieve dysphagia. We retrospectively reviewed the medical records of 6 patients with refractory dysphagia after laparoscopic Nissen fundoplication who underwent laparoscopic conversion to partial fundoplication using a laparoscopic linear stapler. There were no perioperative deaths and no fundoplication-related complications. In short-term follow-up, all patients reported improvement of dysphagia symptoms.

Reoperation for failed reflux surgery

Common causes of failure for gastroesophageal reflux surgery, whether associated with hiatal hernia (HH) or not, include a too tight closure of the crurae, a too tight fundoplication, recurrent HH, total or partial disruption of the wrap and a slipped fundoplication in the chest or down onto the stomach. A laparoscopic approach to patients with failure or complication after antireflux surgery now represents the standard of care after a laparoscopic procedure. The transthoracic approach may be of added value after one or two reoperations, and remains a firm option in more complicated patients.

Reoperative antireflux surgery for dysphagia

BACKGROUND

Troublesome dysphagia is a common indication for redo antireflux surgery (Re-ARS). This study is aimed to analyze the efficacy of Re-ARS in resolving dysphagia and to identify risk factors for persistent or new-onset dysphagia after Re-ARS.

METHODS

A prospectively maintained database was retrospectively reviewed to identify patients after Re-ARS. Dysphagia severity was graded on a scale of 0 to 3 before and after Re-ARS based on responses to a standardized questionnaire. Patients reporting grade 2 or 3 symptoms were considered to have significant dysphagia. Satisfaction was graded using a 10-point analog scale.

RESULTS

Between December 2003 and July 2008, 106 patients underwent Re-ARS. Significant preoperative dysphagia was reported by 54 patients, and impaired esophageal motility was noted in 31 patients. Remedial surgery included redo fundoplication (n = 87), Collis gastroplasty with redo fundoplication (n = 16), and takedown of the fundoplication or hiatal closure alone (n = 3). At least 1 year follow-up period (mean 21.8 months) was available for 92 patients. For patients with significant preoperative dysphagia (n = 46), the mean symptom score declined from 2.35 to 0.78 (p < 0.0001). Persistent dysphagia was reported by 13 patients and new-onset dysphagia by 4 patients. No patients reported grade 3 dysphagia after Re-ARS. Dilations were used to treat 11 patients. Multivariate logistic regression analysis identified Collis gastroplasty (p = 0.03; adjusted odds ratio [OR], 5.74) and preoperative dysphagia (p = 0.01; adjusted OR, 6.80) as risk factors for significant postoperative dysphagia. The overall satisfaction score was 8.3, but certain subsets had significantly lower satisfaction scores. These subsets included patients with esophageal dysmotility (7.1; p = 0.04), patients who required Collis gastroplasty (7.0; p = 0.09), and patients with esophageal dysmotility who required Collis gastroplasty (5.0; p < 0.01).

CONCLUSION

Although dysphagia is a common symptom among patients requiring Re-ARS, intervention provides a significant benefit. Patients with preoperative dysphagia, especially those requiring Collis gastroplasty, are at increased risk for persistent dysphagia and decreased satisfaction after Re-ARS.

Esophagectomy after anti-reflux surgery

OBJECTIVE

There are few data on whether prior fundoplication has an impact on subsequent esophageal resection and reconstruction. The aim of this study is to review our experience with patients undergoing esophagectomy after previous fundoplication.

METHODS

Medical records were reviewed of all patients undergoing esophageal resection from 1988 to 2008 at the Mayo Clinic. Patients with a fundoplication before esophagectomy were compared with a matched control group who had esophagectomy alone.

RESULTS

There were 2313 esophageal resections, and 80 patients had undergone at least 1 previous anti-reflux surgery. Indications for esophagectomy were benign stricture/perforation in 41 patients, cancer in 28 patients, and dysplasia in 11 patients. The surgical approach was Ivor Lewis in 38 patients, left thoracoabdominal in 29 patients, transhiatal in 10 patients, and McKeown in 3 patients. The conduit used was stomach in 70 patients, jejunum in 6 patients, and colon in 3 patients; 1 patient had a diversion and cervical esophagostomy only. Operative mortality occurred in 3 patients (3.7%). Postoperative complications occurred in 50 patients (62.5%), including anastomotic leak in 17 (21.5%). Sixteen patients (20%) required reoperation for complications. Complication, anastomotic leak, and reoperation rates were significantly higher in patients with anti-reflux surgery before esophagectomy compared with matched controls.

CONCLUSION

Esophagectomy after prior anti-reflux surgery is challenging, but the stomach is usually a suitable conduit for esophageal replacement. Patients with a history of anti-reflux surgery who undergo esophagectomy are at significantly increased risk for postoperative complications, anastomotic leak, and need for reoperation.

Outcomes after esophagectomy in patients with prior antireflux or hiatal hernia surgery

BACKGROUND

Esophagectomy is indicated occasionally for the treatment of patients with refractory gastroesophageal reflux disease (GERD) or recurrent hiatus hernia. The purpose of this study was to evaluate the impact of previous gastroesophageal operations on outcomes after esophagectomy for recurrent GERD or hiatus hernia.

METHODS

Using a prospectively accumulated database, a retrospective review was performed to identify patients undergoing esophagectomy for complicated GERD or hiatus hernia. Mortality, perioperative and functional outcomes, and need for reoperation were evaluated, assessing esophagectomy patients who had undergone prior operations for GERD or hiatus hernia.

RESULTS

Of 258 patients with GERD or hiatus hernia undergoing esophagectomy, 104 had undergone a previous operation, with a median interval to esophagectomy of 28 months. Transhiatal resection was accomplished in fewer patients undergoing reoperation (87 of 104 versus 151 of 154; p<0.005). A gastric conduit was used as an esophageal replacement in fewer patients with previous operation(s) (89 of 104 versus 150 of 154; p<0.005). Esophagectomy patients with a history of prior gastroesophageal surgery, as compared with those without, sustained more blood loss and were more likely to require reoperation, and fewer reported good to excellent swallowing function (p<0.05). There was no difference in the occurrence of anastomotic leak.

CONCLUSIONS

Esophagectomy in patients who have undergone prior operations for either GERD or hiatus hernia can be accomplished without thoracotomy and with satisfactory intermediate-term quality of life. Such patients should be evaluated and prepared for the use of alternative conduits should the remobilized stomach prove to be an unsatisfactory esophageal substitute at the time of esophagectomy.

Roux-en-Y reconstruction for failed fundoplication

BACKGROUND

Redo fundoplication has acceptable outcomes in patients with failed previous fundoplications. However, a subset of patients require Roux-en-Y (RNY) reconstruction for symptom relief.

AIM

The aim of this study was to demonstrate safety and efficacy of RNY reconstruction for failed fundoplications.

METHOD

Retrospective review of data on patients who underwent short-limb RNY gastrojejunostomy (GJ) or esophagojejunostomy (EJ) between the years 2005 and 2007 was performed.

RESULTS

Twenty-two patients underwent RNY reconstructions. Fourteen (64%) patients had one, six (27%) patients had two, and 2 (9%) patients had three previous anti-reflux procedures. RNY GJ was performed in 18 patients and EJ in four patients. Gastrectomy was performed in 13 of these patients. Seven patients (32%) had ten major or minor complications within the 30-day postoperative period, without any mortality observed. At a mean follow-up of 23 months, completed in 21 of these patients (95%), the average heartburn score was 0.38 (range, 0-2). The average regurgitation score was 0.23 (range, 0 to2) and the average dysphagia score was 0.7 (range, 0-2). The mean postoperative BMI was 25.4 compared to a preoperative BMI of 31.

CONCLUSION

RNY reconstruction with GJ or EJ for failed anti-reflux procedures is a safe, valid surgical option in difficult situations, where a redo fundoplication is either non-feasible or expected to fail. However, it is associated with higher morbidity.

Long-term outcomes of revisional surgery following laparoscopic fundoplication

BACKGROUND

A small proportion of patients who have laparoscopic antireflux procedures require revisional surgery. This study investigated long-term clinical outcomes.

METHODS

Patients requiring late revisional surgery following laparoscopic fundoplication for gastro-oesophageal reflux were identified from a prospective database. Long-term outcomes were determined using a questionnaire evaluating symptom scores for heartburn, dysphagia and satisfaction.

RESULTS

The database search found 109 patients, including 98 (5.6 per cent) of 1751 patients who had primary surgery in the authors' unit. Indications for surgical revision were dysphagia (52 patients), recurrent reflux (36), mechanical symptoms related to paraoesophageal herniation (16) and atypical symptoms (five). The median time to revision was 26 months. Outcome data were available for 104 patients (median follow-up 66 months) and satisfaction data for 102, 88 of whom were highly satisfied (62.7 per cent) or satisfied (23.5 per cent) with the outcome. Patients who had revision for dysphagia had a higher incidence of poorly controlled heartburn (20 versus 2 per cent; P = 0.004), troublesome dysphagia (16 versus 6 per cent; P = 0.118) and a lower satisfaction score (P = 0.023) than those with recurrent reflux or paraoesophageal herniation.

CONCLUSION

Revisional surgery following laparoscopic fundoplication can produce good long-term results, but revision for dysphagia has less satisfactory outcomes.

Surgical reintervention after failed antireflux surgery: a systematic review of the literature

BACKGROUND

Outcome and morbidity of redo antireflux surgery are suggested to be less satisfactory than those of primary surgery. Studies reporting on redo surgery, however, are usually much smaller than those of primary surgery. The aim of this study was to summarize the currently available literature on redo antireflux surgery.

MATERIAL AND METHODS

A structured literature search was performed in the electronic databases of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials.

RESULTS

A total of 81 studies met the inclusion criteria. The study design was prospective in 29, retrospective in 15, and not reported in 37 studies. In these studies, 4,584 reoperations in 4,509 patients are reported. Recurrent reflux and dysphagia were the most frequent indications; intraoperative complications occurred in 21.4% and postoperative complications in 15.6%, with an overall mortality rate of 0.9%. The conversion rate in laparoscopic surgery was 8.7%. Mean(+/-SEM) duration of surgery was 177.4 +/- 10.3 min and mean hospital stay was 5.5 +/- 0.5 days. Symptomatic outcome was successful in 81.1% and was equal in the laparoscopic and conventional approach. Objective outcome was obtained in 24 studies (29.6%) and success was reported in 78.3%, with a slightly higher success rate in case of laparoscopy than with open surgery (85.8% vs. 78.0%).

CONCLUSION

This systematic review on redo antireflux surgery has confirmed that morbidity and mortality after redo surgery is higher than after primary surgery and symptomatic and objective outcome are less satisfactory. Data on objective results were scarce and consistency with regard to reporting outcome is necessary.
