Laparoscopic fundoplication failures: patterns of failure and response to fundoplication revision

Management of gastroesophageal reflux disease in pediatric patients: a literature review

Gastroesophageal reflux (GER), defined as the passage of gastric contents into the esophagus, is a physiologic process that occurs throughout the day in healthy infants and children. Gastroesophageal reflux disease (GERD) occurs when gastric contents flow back into the esophagus and produce symptoms. The most common esophageal symptoms are vomiting and regurgitation. Lifestyle changes are the first-line therapy in both GER and GERD; medications are explicitly indicated only for patients with GERD. Surgical therapies are reserved for children with intractable symptoms or who are at risk for life-threatening complications of GERD. The laparoscopic Nissen antireflux procedure is the gold standard for the treatment of this pathology. A literature search on PubMed and Cochrane Database was conducted with regard to the management of GERD in children to provide a view of state-of-the-art treatment of GERD in pediatrics.

Evaluation and management of patients with symptoms after anti-reflux surgery

Over the past two decades, there has been an increase in the number of anti-reflux operations being performed. This is mostly due to the use of laparoscopic techniques, the increasing prevalence of gastroesophageal reflux disease (GERD) in the population, and the increasing unwillingness of patients to take acid suppressive medications for life. Laparoscopic fundoplication is now widely available in both academic and community hospitals, has a limited length of stay and postoperative recovery time, and is associated with excellent outcomes in carefully selected patients. Although the operation has low mortality and postoperative morbidity, it is associated with late postoperative complications, such as gas bloat syndrome, dysphagia, diarrhea, and recurrent GERD symptoms. This review summarizes the diagnostic evaluation and appropriate management of such postoperative complications. If a reoperation is needed, it should be performed by experienced foregut surgeons.

Resorbable synthetic mesh supported with omentum flap in the treatment of giant hiatal hernia

Covering a large hiatal hernia with a mesh has become a basic procedure in the last few years. However, mesh implants are associated with high complication rates (esophageal erosion, perforation, fistula, etc.). We propose using a synthetic resorbable mesh supported with an omental flap as a possible solution to this problem. A 54-year-old female patient with a large hiatal defect (9 cm) was laparoscopically implanted with a synthetic resorbable mesh supported with an omental flap. The surgical procedure was successful and the patient was discharged on postoperative day 2. On a follow-up examination 6 months after surgery, she remained free of relapse or complication signs. Supporting an implanted resorbable mesh with an omental flap may be a solution to the problems posed by large esophageal hiatus defects. However, more studies based on larger patient samples and longer follow-up periods are necessary.

MRI patterns of Nissen fundoplication: normal appearance and mechanisms of failure

PURPOSE

The purpose of the study was to assess the role of MR fluoroscopy in the evaluation of post-surgical conditions of Nissen fundoplication due to gastro-oesophageal reflux disease (GERD).

METHODS

A total of 29 patients (21 patients with recurrent/persistent symptoms and eight asymptomatic patients as the control group) underwent MRI of the oesophagus and gastro-oesophageal junction (GEJ) at 1.5 T. Bolus transit of a buttermilk-spiked gadolinium mixture was evaluated with T2-weighted half-Fourier acquisition single-shot turbo spin-echo (HASTE) and dynamic gradient echo sequences (B-FFE) in three planes. The results of MRI were compared with intraoperative findings, or, if the patients were treated conservatively, with endoscopy, manometry, pH-metry and barium swallow.

RESULTS

MRI was able to determine the position of fundoplication wrap in 27/29 cases (93% overall accuracy) and to correctly identify 4/6 malpositions (67%), as well as all four wrap disruptions. All five stenoses in the GEJ were identified and could be confirmed intraoperatively or during dilatation. MRI correctly visualized three cases with motility disorders, which were manometrically confirmed as secondary achalasia. Three patients showed signs of recurrent reflux without anatomical failure.

CONCLUSION

MRI is a promising diagnostic method to evaluate morphologic integrity of Nissen fundoplication and functional disorders after surgery.

KEY POINTS

MRI offers simultaneous morphological and functional imaging in one diagnostic method. MR fluoroscopy offers the possibility to identify the wrap position. MRI enables a non-invasive diagnosis, providing detailed information for the surgeon.

EAES recommendations for the management of gastroesophageal reflux disease

BACKGROUND

Gastroesophageal reflux disease (GERD) is one of the most frequent benign disorders of the upper gastrointestinal tract. Management of GERD has always been controversial since modern medical therapy is very effective, but laparoscopic fundoplication is one of the few procedures that were quickly adapted to the minimal access technique. The purpose of this project was to analyze the current knowledge on GERD in regard to its pathophysiology, diagnostic assessment, medical therapy, and surgical therapy, and special circumstances such as GERD in children, Barrett's esophagus, and enteroesophageal and duodenogastroesophageal reflux.

METHODS

The European Association of Endoscopic Surgery (EAES) has tasked a group of experts, based on their clinical and scientific expertise in the field of GERD, to establish current guidelines in a consensus development conference. The expert panel was constituted in May 2012 and met in September 2012 and January 2013, followed by a Delphi process. Critical appraisal of the literature was accomplished. All articles were reviewed and classified according to the hierarchy of level of evidence and summarized in statements and recommendations, which were presented to the scientific community during the EAES yearly conference in a plenary session in Vienna 2013. A second Delphi process followed discussion in the plenary session.

RESULTS

Recommendations for pathophysiologic and epidemiologic considerations, symptom evaluation, diagnostic workup, medical therapy, and surgical therapy are presented. Diagnostic evaluation and adequate selection of patients are the most important features for success of the current management of GERD. Laparoscopic fundoplication is the most important therapeutic technique for the success of surgical therapy of GERD.

CONCLUSIONS

Since the background of GERD is multifactorial, the management of this disease requires a complex approach in diagnostic workup as well as for medical and surgical treatment. Laparoscopic fundoplication in well-selected patients is a successful therapeutic option.

Long-term maintenance effect of radiofrequency energy delivery for refractory GERD: a decade later

BACKGROUND

Patients with gastroesophageal reflux disease (GERD) often seek alternative therapy for inadequate symptom control, with over 40% not responding to medical treatment. We evaluated the long-term safety, efficacy, and durability of response to radiofrequency treatment of the lower esophageal sphincter (Stretta).

METHODS

Using an intent-to-treat analysis, we prospectively assessed 217 patients with medically refractory GERD before and after Stretta. There was no concurrent control group in the study. Primary outcome measure was normalization of GERD-health-related quality of life (GERD-HRQL) in 70% or greater of patients at 10 years. Secondary outcomes were 50% reduction or elimination of proton pump inhibitors (PPIs) and 60% or greater improvement in satisfaction at 10 years. Successful treatment was defined as achievement of secondary outcomes in a minimum of 50% of patients. Complications and effect on existing comorbidities were evaluated. The results of a 10-year study are reported.

RESULTS

The primary outcome was achieved in 72% of patients (95% confidence interval 65-79). For secondary outcomes, a 50% or greater reduction in PPI use occurred in 64% of patients, (41% eliminating PPIs entirely), and a 60% or greater increase in satisfaction occurred in 54% of patients. Both secondary endpoints were achieved. The most common side effect was short-term chest pain (50%). Pre-existing Barrett's metaplasia regressed in 85% of biopsied patients. No cases of esophageal cancer occurred.

CONCLUSIONS

In this single-group evaluation of 217 patients before and after Stretta, GERD-HRQL scores, satisfaction, and PPI use significantly improved and results were immediate and durable at 10 years.

Hiatal hernia repair with biologic mesh reinforcement reduces recurrence rate in small hiatal hernias

The utility of mesh reinforcement for small hiatal hernia found especially during antireflux surgery is unknown. Initial reports for the use of biological mesh for crural reinforcement during repair for defects greater than 5 cm have been shown to decrease recurrence rates. This study compares patients with small hiatal hernias who underwent onlay biologic mesh buttress repair versus those with suture cruroplasty alone. This is a single-institution retrospective review of all patients undergoing repair of hiatal hernia measuring 1-5 cm between 2002 and 2009. The patients were evaluated based on surgical repair: one group undergoing crural reinforcement with onlay biologic mesh and other group with suture cruroplasty only. Seventy patients with hiatal hernia measuring 1-5 cm were identified. Thirty-eight patients had hernia repair with biologic mesh, and 32 patients had repair with suture cruroplasty only. Recurrence rate at 1 year was 16% (5/32) in patients who had suture cruroplasty only and 0% (0/38) in the group with crural reinforcement with absorbable mesh (statistically significant, P = 0.017). Suture cruroplasty alone appears to be inadequate for hiatal hernias measuring 1-5 cm with significant recurrence rate and failure of antireflux surgery. Crural reinforcement with absorbable mesh may reduce hiatal hernia recurrence rate in small hiatal hernias.

LINX(®) Reflux Management System in chronic gastroesophageal reflux: a novel effective technology for restoring the natural barrier to reflux

Gastroesophageal reflux disease (GERD) results from incompetency of the lower esophageal sphincter that allows the contents of the stomach to reflux into the esophagus, the airways, and the mouth. The disease affects about 10% of the western population and has a profound negative impact on quality of life. The majority of patients are successfully treated with proton-pump inhibitors, but up to 40% have incomplete relief of symptoms even after dose adjustment. The laparoscopic Nissen fundoplication represents the surgical gold standard, but is largely underused because of the level of technical difficulty and the prevalence of side effects. These factors have contributed to the propensity of patients to continue with medical therapy despite inadequate symptom control and complications of the disease. As a consequence, a significant 'therapy gap' in the treatment of GERD remains evident in current clinical practice. The LINX(®) Reflux Management System (Torax Medical, St. Paul, MN, USA) is designed to provide a permanent solution to GERD by augmenting the sphincter barrier with a standardized, reproducible laparoscopic procedure that does not alter gastric anatomy and is easily reversible. Two single-group trials confirmed that a magnetic device designed to augment the lower esophageal sphincter can be safely and effectively implanted using a standard laparoscopic approach. The device decreased esophageal acid exposure, improved reflux symptoms and quality of life, and allowed cessation of proton-pump inhibitors in the majority of patients.

Management of the patient with incomplete response to PPI therapy

Proton pump inhibitors (PPIs) remove most of the acid from the gastroesophageal refluxate. However, PPIs do not eliminate reflux and the response of specific GERD symptoms to PPI therapy depends on the degree to which acid drives those symptoms. PPIs are progressively less effective for heartburn, regurgitation, chest pain and extra-oesophageal symptoms. Hence, with an incomplete PPI response, obtaining an accurate history, detailing which symptoms are 'refractory' and exactly what evidence exists linking these symptoms to GERD is paramount. Reflux can continue to cause symptoms despite PPI therapy because of persistent acid reflux or weakly acidic reflux. Given these possibilities, diagnostic testing (pH or pH-impedance monitoring) becomes essential. Antireflux surgery is an alternative in patients if a clear relationship is established between persistent symptoms, particularly regurgitation, and reflux. Treating visceral hypersensitivity may also benefit the subset of GERD patients whose symptoms are driven by this mechanism.

Surgical management of pediatric gastroesophageal reflux disease

Gastroesophageal reflux (GER) is common in the pediatric population. Most cases represent physiologic GER and as the lower esophageal sphincter (LES) matures and a solid diet is introduced, many of these patients (>65%) experience spontaneous resolution of symptoms by two years of age. Those who continue to have symptoms and develop complications such as failure to thrive, secondary respiratory disease, and others are classified as having gastroesophageal reflux disease (GERD). Goals of GERD treatment include the resolution of symptoms and prevention of complications. Treatment options to achieve these goals include dietary or behavioral modifications, pharmacologic intervention, and surgical therapy. This paper will review the clinical presentation of GERD and discuss options for surgical management and outcomes in these patients.

Gastroesophageal reflux disease treatment: side effects and complications of fundoplication

Even skilled surgeons will have complications after antireflux surgery. Fortunately, the mortality is low (<1%) with laparoscopic surgery, immediate postoperative morbidity is uncommon (5%-20%), and conversion to an open operation is <2.5%. Common late postoperative complications include gas-bloat syndrome (up to 85%), dysphagia (10%-50%), diarrhea (18%-33%), and recurrent heartburn (10%-62%). Most of these complications improve during the 3-6 months after surgery. Dietary modifications, pharmacologic therapies, and esophageal dilation may be helpful. Failures after antireflux surgery usually occur within the first 2 years after the initial operation. They fall into 5 patterns: herniation of the fundoplication into the chest, slipped fundoplication, tight fundoplication, paraesophageal hernia, and malposition of the fundoplication. Reoperation rates range from 0%-15% and should be performed by experienced foregut surgeons.

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.

Laparoscopic Nissen fundoplication in the treatment of Barrett's esophagus - 10 years of experience

Introduction

Barrett's esophagus (BE) is a state in which the distal portion of esophageal mucosa becomes lined with cylindrical epithelium as a result of adaptive remodeling. It is widely accepted that the metaplastic lesions result from chronic irritation with gastric and/or duodenal contents in the course of reflux disease. For many years, research centered on the risk factors of BE and resulting adenocarcinoma. Anti-reflux operations are the only procedures which offer the possibility of treating the cause by restoring the anatomic barrier responsible for guarding against irritating effects of gastroduodenal content on the distal esophagus. Total (i.e. 360°) laparoscopic Nissen fundoplication (LNF) is considered the most effective amongst these procedures. Still, controversies related to the indications for anti-reflux surgery are frequently encountered.

Aim

Retrospective analysis of long-term treatment outcomes in patients with BE subjected to laparoscopic Nissen fundoplication.

Material and methods

The group included 42 BE patients, amongst them 30 men and 12 women. Initially, all the patients were treated conservatively for at least 1 year. The subgroup with dysplasia was subjected to preoperative argon plasma coagulation (APC). From 1 year after surgery (laparoscopic Nissen fundoplication), control biopsy specimens were obtained from the gastroesophageal junction of all the patients.

Results

None of the patients showed the development of esophageal adenocarcinoma during the follow-up period. Furthermore, no cases of dysplasia progression or de novo development of dysplasia were observed in the analyzed group. In the initial 12-24 months after surgery, complete regression of metaplasia was documented in 7 (31.8%) patients from group A, and a reduction in the area of Barrett's metaplasia was observed in another 7 patients (31.8%). Throughout the period of this study, persistent planoepithelial re-epithelialization was observed in 14 (70%) group B patients, i.e. in individuals with baseline dysplasia subjected to preoperative argon plasma ablation. In the remaining patients of this group, the developed changes of BE character were less advanced than at baseline.

Conclusions

Our opinion is that laparoscopic Nissen fundoplication, as a result of high effectiveness, represents the method of choice in the treatment of BE in the case of patients who were qualified for surgery.

Allograft dermal matrix hiatoplasty during laparoscopic primary fundoplication, paraesophageal hernia repair, and reoperation for failed hiatal hernia repair

BACKGROUND

Hiatal repair failure is the nemesis of laparoscopic paraesophageal hernia repair as well as the major cause of failure of primary fundoplication and reoperation on the hiatus. Biologic prosthetics offer the promise of reinforcing the repair without risks associated with permanent prosthetics.

DESIGN

Retrospective evaluation of safety and relative efficacy of laparoscopic hiatal hernia repair using an allograft (acellular dermal matrix) onlay. Patients with symptomatic failures underwent endoscopic or radiographic assessment of hiatal status.

RESULTS

Greater than 6-month follow-up was available for 252 of 450 consecutive patients undergoing laparoscopic allograft-reinforced hiatal hernia repair between January 2007 and March 2011. No erosions, strictures, or persisting dysphagia were encountered. Adhesions were minimal in cases where reoperation was required. Failure of the hiatal repair at median 18 months (6-51 months) was significantly (p < 0.005) different between groups: group A (primary fundoplication with axial hernia ≤ 2 cm), 3.7 %; group B (primary fundoplication with axial hernia 2-5 cm), 7.1 %; group G (giant/paraesophageal), 8.8 %; group R (reoperative), 23.4 %. Additionally, mean time to failure was significantly shorter in group R (247 days) compared with the other groups (462-489 days).

CONCLUSIONS

Use of allograft reinforcement to the hiatus is safe at 18 months median follow-up. Reoperations had a significantly higher failure rate and shorter time to failure than the other groups despite allograft, suggesting that primary repairs require utmost attention and that additional techniques may be needed in reoperations. Patients with hiatal hernias >2 cm axially had a recurrence rate equal to that of patients undergoing paraesophageal hiatal hernia repair, and should be treated similarly.

LINX(™) Reflux Management System: magnetic sphincter augmentation in the treatment of gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD), commonly manifested by heartburn or regurgitation, is a chronic, progressive condition in which failed sphincter function allows the contents of the stomach to reflux into the esophagus, the airways and the mouth. Chronic GERD affects 10% of Western society. The majority of patients receive adequate relief from proton pump inhibitors, but up to 40% have incomplete relief of symptoms that cannot be addressed by increasing the dose of medications. The laparoscopic Nissen fundoplication is the surgical gold standard; however, the level of technical difficulty and its side effects have limited its use to less than 1% of the GERD population. These factors have contributed to the propensity of patients to persist with medical therapy, even when inadequate to control symptoms and complications of the disease. Consequently, a significant gap in the treatment continuum for GERD remains evident in current clinical practice. The LINX(™) Reflux Management System (Torax Medical) is designed to provide a permanent solution to GERD by augmenting the physiologic function of the sphincter barrier with a simple and reproducible laparoscopic procedure that does not alter gastric anatomy and can be easily reversed if necessary.

Multislice computed tomography for the study of complications of gastric fundoplication

The traditional approach to the imaging evaluation of patients after gastric fundoplication is an upper gastrointestinal series obtained by fluoroscopy. In this article, we describe a new technique using multislice computed tomography that we think can be useful to evaluate patients with suspected complications or late failure after gastric fundoplication.

Revision of failed traditional fundoplication using EsophyX transoral fundoplication

Background

Laparoscopic revision of failed traditional fundoplication is difficult and involves risk of gastric, esophageal, and vagal nerve injury that is higher than that of the primary fundoplication. This study assessed feasibility and clinical outcomes of the transoral approach to revision of loose Nissen.

Methods

Between November 2009 and August 2011, a total of 11 patients underwent transoral repair as opposed to 70 patients who underwent laparoscopic or open revision of a failed fundoplication. Subjective and objective outcomes were evaluated with the GERD health-related quality of life (GERD-HRQL) questionnaire and the reflux symptom index (RSI) questionnaire and ambulatory pH testing. The competency of the new antireflux barrier was evaluated by endoscopy. Wilcoxon signed-rank test was used to compare pre- and postoperative variables.

Results

All 11 patients evidenced loosening of the Nissen fundoplication without evidence of hiatal failure. Mean age was 57 years, BMI was 25.1 kg/m², and 4 of 11 (36 %) were female. Indications for operation were abnormal pH-metry off PPIs (6), impedance/pH on PPIs (3), esophagitis (1), and evidence of free reflux on barium swallow (1). One patient developed a postoperative bleed requiring transfusion. Two patients had laparoscopic revision at 6 and 8 months after the transoral procedure. At a median follow-up of 14 (range = 6–28) months, 8/10 patients reported resolution of their primary symptoms. Eight patients had pH testing off PPIs both pre- and postoperatively; median % time with pH <4 improved by dropping from 8.1 % (21–4.8 %) to 0.6 % (13.4–0.01 %) (p = 0.008). Esophageal acid exposure normalized in 5/6 patients. Mean GERD-HRQL score improved significantly by dropping from 28.6 (10.6) preoperatively to 6.7 (6.1) post-TIF (p = 0.016). Mean RSI score improved more than 50 % in 5/7 patients.

Conclusion

Transoral revision of failed traditional fundoplication without herniation is technically feasible. It results in symptomatic and objective improvement of GERD without the risks of laparoscopic dissection for a majority of patients.

Rectus abdominus fascial sheath usage for crural reinforcement during surgical management of GERD: preliminary report of a prospective randomized clinical trial

PURPOSE

Many materials are currently being used to reinforce the crural repair. Perforation, intensive fibrosis, and price are limiting the usage of these materials. Our purpose was to seek an alternative, cheap, always available, and inert material to use for cruroplasty reinforcement.

METHODS

Twenty-four patients participated and were randomly divided into 2 groups (graft+laparoscopic Nissen fundoplication and laparoscopic Nissen fundoplication alone) with 12 patients in each group. Total operation time, postoperative dysphagia rate, dysphagia improvement time, postoperative pain, recurrence, and incisional hernia rate were compared.

RESULTS

There was no difference in terms of study parameters between both groups except for the mean operation time.

CONCLUSIONS

Autograft hiatoplasty seems to be a good alternative for crural reinforcement. It provides safe reinforcement, has the same dysphagia rates as meshless hiatoplasty, and avoids potential complications of redo surgery by minimizing extensive fibrosis. Furthermore, the rectus abdominus sheath is always available and inexpensive.

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.

Five-year efficacy of laparoscopic Nissen fundoplication versus anterior 180° partial fundoplication in the management of reflux esophagitis: A randomized controlled trial

AIM: To evaluate the long-term clinical outcome of laparoscopic Nissen fundoplication versus anterior 180° partial fundoplication in the management of reflux esophagitis.

METHODS: One hundred and seven patients with reflux esophagitis were enrolled and randomly allocated into two groups to undergo laparoscopic Nissen fundoplication (Nissen group) and laparoscopic anterior 180° partial fundoplication (partial fundoplication group). The patients were followed for 5 years after operation, and clinical data, such as the incidences of heartburn, dysphagia, bloating or flatulence, belching ability, and degree of satisfaction with the operation, were collected.

RESULTS: There were no statistical significances between the two groups for the incidence of heartburn symptom and consumption of PPI. Though the incidence of dysphagia was similar between the two groups, the severity of the symptom in the partial fundoplication group was much lower than that in the Nissen group. There is a higher incidence of epigastric bloating, difficulty of belching and flatulence in the Nissen group. The degree of overall satisfaction with the operation was similar between the two groups. Most patients were free of reflux symptoms during the 5-year follow-up period.

CONCLUSION: Laparoscopic anterior 180° partial fundoplication has good and durable anti-reflux effect and is associated with a lower incidence of post-operative complications compared to Nissen fundoplication, and can be employed as a routine procedure for treatment of gastroesophageal reflux disease.

The LINX® reflux management system: confirmed safety and efficacy now at 4 years

BACKGROUND

Sphincter augmentation with the LINX® Reflux Management System is a surgical option for patients with chronic gastroesophageal disease (GERD) and an inadequate response to proton pump inhibitors (PPIs). Clinical experience with sphincter augmentation is now available out to 4 years.

METHODS

In a multicenter, prospective, single-arm study, 44 patients underwent a laparoscopic surgical procedure for placement of the LINX System around the gastroesophageal junction (GEJ). Each patient's baseline GERD status served as the control for evaluations post implant. Long-term efficacy measures included esophageal acid exposure, GERD quality-of-life measures, and use of PPIs. Adverse events and long-term complications were closely monitored.

RESULTS

For esophageal acid exposure, the mean total % time pH < 4 was reduced from 11.9 % at baseline to 3.8 % at 3 years (p < 0.001), with 80 % (18/20) of patients achieving pH normalization (≤ 5.3 %). At ≥ 4 years, 100 % (23/23) of the patients had improved quality-of-life measures for GERD, and 80 % (20/25) had complete cessation of the use of PPIs. There have been no reports of death or long-term device-related complications such as migration or erosion.

CONCLUSIONS

Sphincter augmentation with the LINX Reflux Management System provided long-term clinical benefits with no safety issues, as demonstrated by reduced esophageal acid exposure, improved GERD-related quality of life, and cessation of dependence on PPIs, with minimal side effects and no safety issues. Patients with inadequate symptom control with acid suppression therapy may benefit from treatment with sphincter augmentation.

Laparoscopic prosthetic hiatal reinforcement for large hiatal hernia repair

BACKGROUND

Large hiatal hernia (LHH) is defined by a hiatal defect larger than 6cm; repair is indicated whenever it becomes symptomatic. As the risk of recurrence after most techniques is relatively high, laparoscopic repair with prosthetic reinforcement of the hiatus has been proposed to reduce the recurrence rate. Our technique and outcomes are reported.

PATIENTS AND METHODS

Laparoscopic prosthetic hiatal reinforcement was performed in 58 patients between August 1997 and October 2009. Prolene(®), Mersilene(®), Goretex(®), and Parietex(®) were the four types of prosthetic material used. Since January 2004, the double-sided V shaped Crurasoft(®) mesh was introduced. Surgical evaluation was based on anatomical and functional criteria: the anatomical results included the presence of recurrent hiatal hernia or esophageal stricture as evaluated by an upper gastrointestinal (UGI) series; functional evaluation was based on a questionnaire concerning long-term patient satisfaction according to the Visick score. Median follow-up was 51 months.

RESULTS

Postoperative UGI series were performed during the initial hospitalization in 37 patients: results were judged to be satisfactory. A routine follow-up UGI series was obtained at 8 months and one year in 46 patients. Two patients underwent reoperation for lower esophageal stricture at 6 months and 16 months. Forty-five patients (77.6%) were reevaluated. Of these, 29 patients (64.4%) were free of symptoms with a good quality of life, eight patients (17.7%) complained of moderate dysphagia and two patients (4.4%) had severe dysphagia. Four patients (8.9%) had moderate pyrosis while severe pyrosis requiring long term PPI treatment was observed in three patients (6.7%). No prosthesis-induced ulceration or perforation was noted. Late follow-up UGI series, performed in 21 patients, showed two patients with severe stricture and a single case of recurrence, but neither of these patients required surgical management.

CONCLUSION

The addition of mesh reinforcement to surgical repair of large hiatal defects is safe and beneficial in terms of quality of life.

Prospective randomized trial of laparoscopic Nissen fundoplication with anterior versus posterior hiatal repair: late outcomes

BACKGROUND

The technique used for hiatal closure in laparoscopic Nissen fundoplication might have an impact on the risk of postfundoplication dysphagia and hiatal herniation. In 1997, we commenced a randomized trial to evaluate the impact of anterior versus posterior hiatal repair techniques on these outcomes. In the present study, we evaluated the 10-year outcomes from this trial.

METHODS

A total of 102 patients were randomized to undergo laparoscopic Nissen fundoplication with either anterior (47 patients) or posterior (55 patients) repair of the diaphragmatic hiatus. Outcomes were assessed using standardized clinical assessment scores that evaluated reflux symptoms, dysphagia, and satisfaction with the outcome following surgery.

RESULTS

Clinical outcomes 10 years after surgery were available for 93% of patients, and outcome scores were obtained for 43 patients in each group. Patients undergoing anterior hiatal repair were less likely to report dysphagia for lumpy solid foods (14.0% vs. 39.5%, p = 0.01), although there were no significant differences in dysphagia outcomes for six other dysphagia assessment scores. There were no differences between the two groups for reflux symptoms, medication use, and overall satisfaction with the outcome of surgery.

CONCLUSIONS

At the 10-year follow-up, the outcomes for the two groups were similar. Anterior hiatal repair is an acceptable technique for hiatal closure during laparoscopic Nissen fundoplication.

Quality of life after collis gastroplasty for short esophagus in patients with paraesophageal hernia

BACKGROUND

Collis gastroplasty is an important component of laparoscopic giant paraesophageal hernia (GPEH) repair in patients with persistent shortened esophagus after aggressive laparoscopic mobilization. Concerns remain, however, regarding symptomatic outcomes compared with fundoplication alone. This study assessed the impact of Collis gastroplasty on quality of life after laparoscopic GPEH repair.

METHODS

We performed 795 nonemergent laparoscopic GPEH repairs with fundoplication (with Collis, n = 454; fundoplication alone, n = 341). Radiographic follow-up and symptom assessment were obtained a median 22 months and 20 months, respectively, after fundoplication alone and 36 and 33 months, respectively, after Collis (p < 0.001). Radiographic recurrence, reoperation for recurrent hernia or intolerable symptoms, overall symptom improvement, and quality of life were examined.

RESULTS

Compared with fundoplication alone, Collis patients had significantly larger GPEH (p = 0.027) and fewer comorbidities (p = 0.002). Radiographic recurrences were similar (p = 0.353). Symptom improvement was significant for both (p < 0.001), although Collis was associated with better pain resolution (p < 0.001) and less gas bloat (p = 0.003). Quality of life was good to excellent in 88% (90% Collis versus 86% fundoplication alone, p = 0.17).

CONCLUSIONS

Symptomatic outcomes after laparoscopic fundoplication with Collis gastroplasty are excellent and comparable with those of fundoplication alone. These results confirm that utilization of Collis gastroplasty, based on intraoperative assessment for shortened esophagus, is not detrimental to the overall outcome or quality of life associated with the laparoscopic approach to GPEH. Collis gastroplasty is recommended as an important procedure in the surgeon's armamentarium for laparoscopic repair of GPEH.

Laparoscopic redo fundoplication for intrathoracic migration of wrap

Laparoscopic fundoplication is fast emerging as the treatment of choice of gastro-esophageal reflux disease. However, a complication peculiar to laparoscopic surgery for this disease is the intrathoracic migration of the wrap. This article describes a case of a male patient who developed this particular complication after laparoscopic total fundoplication. Following a trauma, wrap migration occurred. The typical history and symptomatology is described. The classical Barium swallow picture is enclosed. Laparoscopic redo fundoplication was carried out. The difficulties encountered are described. Postoperative wrap migration can be suspected clinically by the presence of a precipitating event and typical symptomatology. Confirmation is by a Barium swallow. Treatment is by redo surgery.

A comparison of pre-operative comorbidities and post-operative outcomes among patients undergoing laparoscopic nissen fundoplication at high- and low-volume centers

INTRODUCTION

Commonly cited data promoting laparoscopic Nissen fundoplication (LNF) as safe and efficacious are typically published by single centers, affiliated with teaching institutions with a high volume of cases, but LNF is not universally performed at these hospitals. The purpose of this study is to assess where these procedures are being done and to compare pre-operative comorbidities and post-operative outcomes between high-and low-volume centers using a state-wide inpatient database.

METHODS

This is a retrospective study using data from the North Carolina Hospital Association Patient Data System. Selected patients include adults (>17 years old) that have undergone laparoscopic Nissen fundoplication for gastroesophageal reflux disease as an inpatient from 2005 to 2008. Patients that underwent operative management for emergent purposes or had associated diagnoses of esophageal cancer or achalasia were excluded from the study. High-volume centers were defined as institutions that performed ten or more LNFs per year averaged over a period of 4 years. Comparative statistics were performed on comorbidities and complications between high- and low-volume centers.

RESULTS

A total of 1,019 patients underwent LNF for GERD in North Carolina between 2005 and 2008 in the inpatient setting. High-volume centers performed 530 LNFs (52%) while low-volume centers performed 489 LNFs (48%). Patients at high-volume centers were older (median 52.5 years old vs. 49.0 years old, p = 0.019), had a higher incidence of diabetes (13.4% vs. 8.8%, p = 0.026), chronic obstructive pulmonary disease (5.1% vs. 2.0 %, p = 0.015), hyperlipidemia (9.6% vs. 4.7%, p = 0.004), and cystic fibrosis (2.8% vs. 0.8%, p = 0.03). Patients with a history of transplantation were also more likely to undergo LNF at a high-volume center (15.8% vs. 1.6%, p < 0.0001). There were no deaths among the two groups and also no difference between median length of stay (2.7 days for high-volume center vs. 2.6 days for low-volume center). Low-volume centers had a higher incidence of intraoperative accidental puncture or laceration (3.3% vs. 0.9%, p = 0.017) while high-volume centers had a higher incidence of atelectasis (5.3% vs. 2.5%, p = 0.031).

CONCLUSION

A significant proportion of the LNFs in North Carolina are performed at low-volume centers. High-volume centers perform LNF on older patients with more comorbidities. Low-volume centers have three times more accidental perforations, yet there is no detectable difference in mortality or median length of stay. It is impossible to tell if these perforations are managed at these low-volume centers or transferred to facilities with a higher level of care. These findings argue for regionalization of LNF and for a reevaluation of the global safety of this operation.

Long-term results after laparoscopic reoperation for failed antireflux procedures

BACKGROUND

Surgery for failed antireflux procedures is technically more demanding than primary fundoplication. The success rate does not equal that of the primary procedures. This retrospective analysis aimed to assess long-term subjective and objective outcomes in patients who underwent laparoscopic surgery for fundoplication failure.

METHODS

Objective and subjective outcomes were assessed by radiological and endoscopic methods, symptom questionnaire and quality-of-life index at a minimum follow-up of 12 (mean 75·8) months.

RESULTS

The study included 129 consecutive patients who had laparoscopic redo surgery after fundoplication had failed. The most frequent patterns of failure were hiatal herniation (50 patients) and slippage (45). Resolution of the symptoms that led to redo surgery was achieved in 27 of 37 and 11 of 16 patients operated for recurrence and for dysphagia respectively. Objective failure was demonstrated in 16 of 39 patients with herniation and six of 22 with slippage. Seven patients underwent an additional surgical procedure.

CONCLUSION

Long-term assessment of objective and subjective results after laparoscopic repair for failed fundoplication revealed a high failure rate that increased with the length of follow-up. Unexpected and untreated oesophageal shortening may be responsible for this failure rate.

Simple suture or prosthesis hiatal closure in laparoscopic repair of paraesophageal hernia: a retrospective cohort study

Laparoscopic repair of paraesophageal hernia (PEH) involves removal of the hernia sac, cruroplasty, and fundoplication. Mesh application to cruroplasty seems to reduce hernia recurrence rate, but may be associated with dysphagia. The aim of the study was to review the clinical and laboratory outcomes of a series of patients with PEH after laparoscopic repair. Patients with PEH, who had laparoscopic repair and 1-year postoperative follow-up, were included in the study. Pre- and postoperative testing included symptom questionnaires, barium esophagogram, pH-monitoring, barium swallow testing. In the first half cases, suturing of large hernia gaps was reinforced with prosthesis (PR), whereas in the second half only suture cruroplasty (SC) was performed. Sixty-eight patients (36 male) with PEH were included in the study. There were no conversions to open. Postoperatively, dysphagia grading was significantly correlated to esophageal transit time (P < 0.001). There were seven recurrences; one paraesophageal and six wrap migrations. Also, four cases with stenosis were identified all in the PR group. Dysphagia was more common (P= 0.05) and esophageal transit more delayed (P= 0.034) after PR than after SC. Two revisions, one for esophageal stenosis and one for recurrent PEH, derived from the SC group. Reflux was more common after Toupet fundoplication than after Nissen fundoplication (NF) (P= 0.031) in patients with impaired esophageal motility. Laparoscopic repair of PEH with SC is associated with satisfactory clinical outcomes and low rate of wrap migration, at least similar to PR hiatal repair. NF is effective as an antireflux procedure in all cases.

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.

Laparoscopic sphincter augmentation device eliminates reflux symptoms and normalizes esophageal acid exposure: one- and 2-year results of a feasibility trial

OBJECTIVES

One- and 2-year evaluation of a feasibility trial (clinicaltrials.gov registration numbers NCT01057992, NCT01058070, and 01058564) to assess the safety and efficacy of a laparoscopically implanted sphincter augmentation device for the treatment of gastroesophageal reflux disease (GERD).

METHODS

A sphincter augmentation device (LINX Reflux Management System; Torax Medical, Shoreview, MN), designed to prevent reflux due to abnormal opening of the lower esophageal sphincter (LES), was laparoscopically implanted at the gastroesophageal junction in 44 patients. At baseline, all patients had abnormal esophageal acid exposure on 24-hour pH monitoring and improved, but persistent, typical GERD symptoms while on acid suppression therapy with proton pump inhibitors (PPIs). The device comprises a miniature string of interlinked titanium beads, with magnetic cores, placed around the gastroesophageal junction. The magnetic bond between adjacent beads augments sphincter competence. The beads temporarily separate to accommodate a swallowed bolus, allow belching or vomiting, and reapproximate to augment the LES in the closed position. Patients were evaluated after surgery by GERD Health-Related Quality of Life symptom score, PPI usage, endoscopy, esophageal manometry, and 24-hour esophageal pH monitoring.

RESULTS

The total mean GERD Health-Related Quality of Life symptom scores improved from a mean baseline value of 25.7 to 3.8 and 2.4 at 1- and 2-year follow-up, representing an 85% and 90% reduction, respectively (P < 0.0001). Complete cessation of PPI use was reported by 90% of patients at 1 year and by 86% of patients at 2 years. Early dysphagia occurred in 43% of the patients and self-resolved by 90 days. One device was laparoscopically explanted for persistent dysphagia without disruption of the anatomy or function of the cardia. There were no device migrations, erosions, or induced mucosal injuries. At 1 and 2 years, 77% and 90% of patients had a normal esophageal acid exposure. The mean percentage time pH was less than 4 decreased from a baseline of 11.9% to 3.1% (P < 0.0001) at 1 year and to 2.4% (P < 0.0001) at 2 years. Patient satisfaction was 87% at 1 year and 86% at 2 years.

CONCLUSIONS

The new laparoscopically implanted sphincter augmentation device eliminates GERD symptoms without creating undue side effects and is effective at 1 and 2 years of follow-up.

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.

Mesh erosion as a complication of laparoscopic fundoplication with prosthetic hiatal closure: report of a case

BACKGROUND

Laparoscopic fundoplication has become the standard procedure for surgical management of gastroesophageal reflux disease. Simple cruroplasty is associated with a high recurrence rate and most authors recommend the use of prosthetic meshes for crural closure.

METHODS

Herein we report a patient who was admitted with the complaint of severe dysphagia a year after laparoscopic fundoplication with prosthetic hiatal closure.

RESULTS

The patient presented with mesh erosion into the esophagus and required a distal esophageal resection.

CONCLUSIONS

This case demonstrates that appropriate surgical technique is important for preventing mesh-related complications. A small-sized mesh should be placed so as to have no contact with the esophagus and should be secured sufficiently to the diaphragmatic crura to avoid the potential complications of mesh reinforcement.

Internal herniation of the anterior gastric wall through an attenuated Nissen Fundoplication wrap: an unusual complication and its laparoscopic management

Laparoscopic Nissen fundoplication is the treatment of choice for medically refractive gastro-oesophageal reflux disease as it is considered safe, cost efficient and effective. Unusual variants of internal abdominal herniation, however, have been reported after the procedure. Here, we present a case of a 38-year-old woman who presented 3 months after a successful laparoscopic Nissen Rossetti fundoplication, with abdominal pain and persistent vomiting. Abdominal X-ray at the time of admission was normal but CT suggested internal herniation of the stomach. Laparoscopy confirmed internal herniation of the anterior wall of the stomach through an attenuated fundoplication wrap. We show that a prompt diagnosis of this complication, which we have not found reported previously in the English literature, can be achieved by CT, permitting an early laparoscopic intervention to preserve the viability of the obstructed segment of stomach.

Medical comorbidities should not deter the application of laparoscopic fundoplication

INTRODUCTION

Laparoscopic Nissen fundoplication offers significant improvement in gastroesophageal reflux disease (GERD) symptom severity and frequency. This study was undertaken to determine the impact of preoperative medical comorbidities on the outcome and satisfaction of patients undergoing fundoplication for GERD.

METHODS

Prior to fundoplication, patients underwent esophageal motility testing and 24-h pH monitoring. Before and after fundoplication, the frequency and severity of reflux symptoms were scored using a Likert scale. Medical comorbidities were classified by organ systems, and patients were assigned points corresponding to the number of medical comorbidities they had. In addition, all patients were assigned Charlson comorbidity index (CCI) scores according to the medical comorbidities they had. A medical comorbidity was defined as a preexisting medical condition, not related to GERD, for which the patient was receiving treatment. Analyses were then conducted to determine the impact of medical comorbidities as well as CCI score on overall outcome, symptom improvement, and satisfaction.

RESULTS

Six hundred and ninety-six patients underwent fundoplication: 538 patients had no medical comorbidities and 158 patients had one or more medical comorbidities. Preoperatively, there were no differences in symptom severity and frequency scores between patients with or without medical comorbidities. Postoperatively, all patients had improvement in their symptom severity and frequency scores. There were no differences in postoperative symptom scores between the patients with medical comorbidities and those without. The majority of patients were satisfied with their overall outcome; there was no relationship between the number of medical comorbidities and satisfaction scores. These findings were mirrored when patients' CCI scores were compared with satisfaction, overall outcome, and symptom improvement.

CONCLUSION

These results promote further application of laparoscopic Nissen fundoplication, even for patients with medical comorbidities.

Hiatal mesh is associated with major resection at revisional operation

BACKGROUND

Mesh-assisted hiatal closure during foregut surgery is increasing. Our aim was to evaluate the complications that follow revisional foregut surgery. Specifically, we compared surgical indications and perioperative outcomes between patients with and without prior hiatal mesh (PHM).

METHODS

We conducted an institutional review board (IRB)-approved retrospective cohort study from a single tertiary-care referral center. Over 37 months, 91 patients underwent revisional foregut surgery. We excluded 13 cases including operations performed primarily for obesity or achalasia. Of the remaining 78 patients, 10 had PHM and 68 were nonmesh patients (NM).

RESULTS

The groups were similar in terms of age, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, and rates and types of anatomic failure. Compared with NM patients, PHM patients had increased estimated blood loss (410 vs. 127 ml, p < 0.01) and operative time (4.07 vs. 2.89 h, p < 0.01). The groups had no difference in perioperative blood transfusion or length of stay. Complete fundoplication was more commonly created in NM patients (2/10 vs. 42/68, p = 0.03). Three of the 10 PHM patients and 3 of the 68 NM patients required major resection. Therefore, PHM patients had 6.8-fold increased risk of major resection compared with NM patients [95% confidence interval (CI) = 1.585, 29.17; p = 0.05]. The NM patients with multiple prior hiatal operations had 4.6-fold increased risk of major resection compared with those with one prior operation (95% CI = 2.919, 7.384; p = 0.03). In PHM patients, however, the number of prior hiatal operations was not associated with major resection.

CONCLUSIONS

PHM is associated with increased risk of major resection at revision. The pattern of failure was not different in patients with hiatal mesh, suggesting that hiatal mesh does not eliminate the potential for revision. When performing hiatal herniorrhaphy, the increased risk of recurrence without mesh must be weighed against the potential risk for subsequent major resection when using mesh.
