(d) Prolonged pH monitoring
Either 24h catheter based or 48h Bravo pH monitoring off acid suppression therapy is the gold standard to assess for extent of gastro-esophageal reux. In our experience impedance reux testing on therapy has not been very useful.
(e) Gastric Emptying Study (GES)
Nuclear medicine GES is useful to assess presence and degree of delayed gas­tric emptying and will help direct the need for gastric drainage procedure. A 4h study is preferable and moderate to severe delayed GE should be addressed with either a pyloroplasty or anterectomy at the time of redo surgery.
14.3 How toClassify Failed Fundoplication?
Failed fundoplication have most commonly classied anatomically based on recur­rence of hiatus hernia, relative location of the fundoplication to lower esophagus and geometry of the fundoplication. Jobe etal. [6] described in detail endoscopic charac­teristics of technically sound fundoplication and laid out the criteria for endoscopic
216

assessment. However, majority of endoscopic assessment done in the community do not describe the fundoplication adequately. An audit of reported endoscopic ndings by community gastroenterologists by Juhasz etal. [3] revealed a shockingly low con­cordance with subsequent ndings of an experienced foregut surgeon. Surprisingly they found that nearly a 1/3rd of the endoscopic reports did not even mention a previ­ous fundoplication while majority of the reports simply stated, “fundoplication changes noted” without any specic description. Proper and uniform endoscopic assessment of fundoplication is an import aspect in assessing causes of failure and devising a man­agement strategy. Various terminologies have been used to describe failed fundoplica­tion anatomy. Most commonly terms such as recurrent hiatus hernia, slipped, intra-thoracic, disrupted, twisted and telescopic fundoplication have been used. They have also been used interchangeably without accepted denitions. For example one may classify an intra-thoracic fundoplication is “slipped into the chest” or “telescoping in to the chest” while a fundoplication at the hiatus with GEJ above the hiatus may be called “ slipped below the GJ” or recurrent HH” or “misplaced fundoplication”.
Horagan etal. [7] were the rst to propose an anatomic classication for failed
fundoplication. They classied failed fundoplication into type IA (both EGJ and Fundoplication above the hiatus), type 1B (GEJ above hiatus with fundoplication below the hiatus, type II (only a portion of fundus/ greater curvature herniated above the hiatus) and type III ( body of the stomach used to create the wrap rather than the fundus) (Table14.1). More recently a standardized system based on location of the GEJ relative to the hiatus, the fundoplication relative to the GEJ and geometry of the fundoplication has been proposed by Mittal etal. [8] (Table14.2). Each of the com­ponent E, S, F and P are given a ‘sufx’ and nal description is given as E
xSxFxPx
.
While not discussed in literature till now a failed fundoplication may be better clas-
sied based on the underlying physiological derangements. Normal gastrointestinal function requires the ante-grade esophageal clearance thru the gastroesophageal junc­tion (GEJ) and gastric clearance thru the pylorus along with a competent lower esoph­ageal junction (LES) to prevent backow. Furthermore, some degree of GEJ complex incompetence (permissiveness) is desirable to allow for gastric venting i.e. belching.
Poor esophageal emptying due to either poor motility and/or non-compliant
lower esophageal sphincter- fundoplication (LES-F) complex will manifest with dysphagia and bland regurgitation. Not infrequently, in patients with poor motility, there may be aspiration associated cough or throat clearance. The patient or an inex­perienced physician may confuse these symptoms as recurrent reux, especially if regurgitation and cough are more prominent. On the other hand a non-functioning LES-F complex with poor competence allowing abnormal backow of gastric con­tents will present with true recurrent GERD.Underlying delayed gastric emptying either pre-existing or due to vagal injury will present with bloating, nausea and

epigastric pain, which may again be interpreted as recurrent GERD by patients and physicians alike. Not infrequently these symptoms become more prominent once reux symptoms are addressed specially in patients with underlying Irritable Bowel Syndrome (IBS). There is a signicant overlap in the clinical spectrum of GERD and IBS. Careful assessment of each dissatised post-fundoplication patient is essential to identify the underlying physiological derangement and one must be aware that more than one derangement may co-exist.
In the dissatised post-fundoplication patient, the anatomical and physiological
ndings should be concordant with symptomatology before surgical re-intervention is attempted. In our experience, patients with functional complaints without supportive objective ndings may present with “failed fundoplication” and as “dissatised patients” and are best addressed with reassurance and counseling rather than surgical re-intervention.
14.4 Causes ofFailed Fundoplication

14.4.1 Poor Patient Selection

Objective evidence of the presence of pathological reux is important before a sur­gical fundoplication. Campos etal. showed that a good response to acid- suppression therapy, abnormal preoperative 24-h pH score and typical symptoms were good predictors of success of fundoplication [9]. While logical, it is surprising that it is
218
S. Mittal
not uncommon for patients with failed fundoplication to not have had an adequate documentation of disease prior to surgery. In these patients, it is hazardous to guess whether the surgery has failed or the disease never existed.
In our opinion, ‘objective’ evidence of GERD are: a classical history of heart-
burn or regurgitation with a very good response to acid suppressive therapy or grade B or greater reux esophagitis noted on endoscopy. In absence of these, an elevated 24-h pH score as measured by prolonged monitoring off acid suppression is consid­ered gold standard test.
In addition to above clinical scenario, esophago-gastric motility assessment
should be done prior to surgery. High-resolution manometry and video esophagram are used to assess esophageal function and a gastric emptying study is used as indi­cated by patient symptoms to assess gastric motility. Additionally we strongly advo­cate that the operating surgeon performs an endoscopic assessment preferably pre-operatively and if not possible in the operative room prior to surgery.
Common foregut symptoms of heartburn, regurgitation and dysphagia span the
gamut of underlying esophageal disorders from GERD to Achalasia and not infre­quently are simply functional. Included in these are scleroderma patients who often present with severe reux. Precise diagnosis is needed to direct appropriate surgical procedure. Patients with scleroderma and primary aperistalsis (non– Achalasia) may be better managed with primary laparoscopic Roux-en-Y gastric bypass (LRYGB) rather than a partial fundoplication.

14.4.2 Improper Surgical Technique

Multitude of fundoplication congurations both via thoracic and abdominal cavity have been described ranging from partial anterior or posterior to a complete fundo­plication. All types of fundoplications require obtaining an adequate intra- abdominal length of the esophagus around which the fundus is wrapped such that the entire complex lays tension free below a closed hiatus.
The surgical technique needs to sufciently mobilize the mediastinal esophagus
to achieve adequate infra-diaphragmatic esophageal length. The crus pillars need to be approximated to close the hiatus with or without mesh reinforcement. Finally, the fundus (part of the stomach above an imaginary horizontal plane from the GEJ) is wrapped and anchored around the distal esophagus. Inadequate esophageal length will result in the positioning of fundoplication around the proximal stomach result­ing in a “slipped wrap”. Inadequate integrity of crus closure will result in re­herniation of the GEJ above the hiatus with (herniated) or without (slipped) fundoplication. Using the body of the stomach rather than fundus to create the ‘fun­doplication’ usually results in a twisted fundoplication. We routinely perform and strongly recommend that an intra-operative endoscopy should be done to assess fundoplication prior to nishing the procedure.
Inadequate attention to these essential surgical steps will increase the likelihood
of “failed fundoplication”.

14.4.3 Inadequate Patient Counseling

A correctly created fundoplication increases barrier pressure and decreases the compliance (i.e., permissiveness) of the GEJ compared to the non-operative state. This requires patients to eat slowly and to chew the food bolus thoroughly, other­wise they risk experiencing dysphagia. Additionally, given the inherent loss of tran­sient lower esophageal sphincter relaxations (TLESRs) after the fundoplication, patients may not be able to belch easily, and must avoid carbonated beverages espe­cially in the immediate post-operative period. It is imperative that the patients be counseled to be cautious and expect these symptoms in the early post-operative period. These tend to resolve to a great extent in the rst few weeks following fundoplication.
Retching, gagging and vomiting increase the likelihood of wrap herniation or
disruption, resulting in recurrent GERD.This is a life-time caution that the patients must be aware of and take precautions against and, have easy and ready access to anti-emetics. We have also encountered some patients who gag themselves during vigorous tongue cleansing and this increases failure. Simple counselling to avoid this has helped tremendously [10].
Additionally, it has been proposed that heavy lifting should be avoided in the
early post-operative period to allow for healing of apposed tissues. Comprehensive patient counseling should improve patient compliance with post-operative care and help reduce failure rates.

14.4.4 Fundoplication/Hiatus Disruption

Crus closure and fundoplication are secured with sutures. Natural forces and tissue characteristics may slowly or abruptly disrupt these anchoring sutures and the scar­ring, resulting in recurrent hiatus hernia and or disrupted fundoplication. Use of synthetic mesh has been shown to decrease recurrence of hiatus hernia but is also associated with increased incidence of severe complications [11, 12]. On the other hand, bio-prosthesis, though safer, have been shown to decrease only short term recurrence without affecting long term recurrence rate [13]. Improved understand­ing of factors leading to recurrent hiatus hernia and development of better surgical techniques/tools including mesh is needed to decrease these causes of failure.

14.4.5 Patient Body Habitus

Obesity is a risk factor for GERD and prevalence of obesity has dramatically increased in the Western world especially in the US.Perez etal. [14] were the rst to report that morbid obesity is associated with poor outcomes after primary
220
S. Mittal
anti- reux surgery. However, others [5] have argued that obesity does not affect outcomes. However, most surgeons agree that fundoplication may not be the best procedure for reux control in morbidly obese patients. Laparoscopic Roux en Y Gastric Bypass (LRYGB) is an excellent anti-reux operation that additionally pro­vides for signicant weight loss and it’s associated salutatory effects on health. Most
2
surgeons would steer morbidly obese patients (BMI>35kg/m
2
as primary intervention. While BMI>35kg/m
has been used as a cut of to direct
) towards a LRYGB
towards bariatric procedure a study by Akimoto etal. [15] showed that patients with
2
BMI>30kg/m
have similar patterns of failure after fundoplication as those with BMI > 35 kg/m2 and these are distinct from failure patterns in patients with BMI<30kg/m2. Performing a fundoplication in a morbidly obese patient can be judged partly a wrong patient choice and partly a wrong procedure choice, but occa­sionally it has to be considered in severely symptomatic patients (especially with volume regurgitation and pulmonary disease) if insurance denies coverage for bar­iatric procedure.

14.5 Conclusions

Recurrent GERD after fundoplication is a complex situation and requires exclusion of other diagnoses which may mimic GERD symptoms (delayed gastric emptying or post fundoplication achalasia) as well as separating the real symptoms from func­tional ones. Not infrequently, an anatomically distorted fundoplication will not have any associated symptoms and these should not undergo redo surgery. In cases with objective recurrence of the disease, many underlying factors—both patient and technical, may be responsible and must be explored to avoid failure of redo surgery. In certain situations such as missed short esophagus or failure to create a symmetri­cal fundoplication, there is technical inadequacy or surgical inexperience. However, non-identication of severe dysmotility or even achalasia and delayed gastric emp­tying, and proceeding with fundoplication should be diligently avoided.
What Is the Current Knowledge and What Future Direction Is Required
• Laparoscopic anti-reux surgery in form of hiatus hernia repair and fundo­plication is the gold standard for denitive management of pathological GERD. Excellent patient centered outcomes have been reported with greater than 90% patient satisfaction at 10 years.
• A subset of patients require re-operative intervention for failed fundoplica­tion which is technically more difcult and associated with increased peri-operative morbidity along with lesser patient oriented outcomes compared to primary fundoplication.

• A uniformly accepted and widely endorsed denition of what constitutes a failed fundoplication is needed which may help tailor the subsequent treat­ment strategies.
• Understanding the causes of failure need to be elucidated and best strate­gies to minimize these undertaken.
• Additionally, surgical outcomes of community centers (where majority of the procedures are done) are less than stellar and have scared patients and referring physicians alike resulting in signicant decline in use of the procedure.
• Future undertakings need to critically assess learning curve for laparo­scopic anti-reux surgery and incorporating appropriate curricula for train­ing surgeons to work-up patients prior to surgical intervention.

Management ofRecurrent Paraesophageal Hernia

15.1 Introduction

Laparoscopy has become the standard approach for management of most benign foregut disease including antireux and hiatal hernia repair. Anatomic recurrence after repair of paraesophageal hernias is high, however, the clinical signicance of such ndings seems to be less relevant [1]. Reoperative foregut surgery has a sig­nicantly higher morbidity and mortality than their primary counterparts. Fortunately, recurrence leading to reintervention is far less common, with a 10 year cumulative risk close to 7% [2].
The risk of recurrence is likely multifactorial, and many different factors have been investigated. The best results are typically achieved during initial intervention. Despite some controversies, complete mediastinal dissection and sac reduction, adequate esophageal length, crural closure, and a well constructed fundoplication, constitute some of the surgical principles to be followed at the time of paraesopha­geal hernia repair [1]. Recently, the role of preoperative body mass index has been taken into consideration as one of the most important factors that predict recurrence after repair [3].
The goal of this chapter is to review the clinical presentation, preoperative eval­uation, and surgical planning relevant to repair of recurrent paraesophageal hernias.
