Results of laparoscopic reoperation for failed antireflux surgery: does the indication for redo surgery affect the outcome?

Management of Adults With Esophageal Atresia

Esophageal atresia (EA) with or without trachea-esophageal fistula is relatively common congenital malformation with most patients living into adulthood. As a result, care of the adult patient with EA is becoming more common. Although surgical repair has changed EA from a fatal to a livable condition, the residual effects of the anomaly may lead to a lifetime of complications. These include effects related to the underlying deformity such as atonicity of the esophageal segment, fistula recurrence, and esophageal cancer to complications of the surgery including anastomotic stricture, gastroesophageal reflux, and coping with an organ transposition. This review discusses the occurrence and management of these conditions in adulthood and the role of an effective transition from pediatric to adult care to optimize adult care treatment.

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.

When should we use mesh in laparoscopic hiatal hernia repair? A systematic review

The use of mesh in laparoscopic hiatal hernia repair (LHHR) remains controversial. The aim of this systematic review was to determine the usefulness of mesh in patients with large hiatal hernia (HH), obesity, recurrent HH, and complicated HH. We performed a systematic review of the current literature regarding the outcomes of LHHR with mesh reinforcement. All articles between 2000 and 2020 describing LHHR with primary suturing, mesh reinforcement, or those comparing both techniques were included. Symptom improvement, quality of life (QoL) improvement, and recurrence rates were evaluated in patients with large HH, obesity, recurrent HH, and complicated HH. Reported outcomes of the use of mesh in patients with large HH had wide variability and heterogeneity. Morbidly obese patients with HH should undergo a weight-loss procedure. However, the benefits of HH repair with mesh are unclear in these patients. Mesh reinforcement during redo LHHR may be beneficial in terms of QoL improvement and hernia recurrence. There is scarce evidence supporting the use of mesh in patients undergoing LHHR for complicated HH. Current data are heterogeneous and have failed to find significant differences when comparing primary suturing with mesh reinforcement. Further research is needed to determine in which patients undergoing LHHR mesh placement would be beneficial.

A retrospective multicenter analysis on redo-laparoscopic anti-reflux surgery: conservative or conversion fundoplication?

BACKGROUND

Nearly 20% of patients who undergo hiatal hernia (HH) repair and anti-reflux surgery (ARS) report recurrent HH at long-term follow-up and may be candidates for redo surgery. Current literature on redo-ARS has limitations due to small sample sizes or single center experiences. This type of redo surgery is challenging due to rare but severe complications. Furthermore, the optimal technique for redo-ARS remains debatable. The purpose of the current multicenter study was to review the outcomes of redo-fundoplication and to identify the best ARS repair technique for recurrent HH and gastroesophageal reflux disease (GERD).

METHODS

Data on 975 consecutive patients undergoing hiatal hernia and GERD repair were retrospectively collected in five European high-volume centers. Patient data included demographics, BMI, techniques of the first and redo surgeries (mesh/type of ARS), perioperative morbidity, perioperative complications, duration of hospitalization, time to recurrence, and follow-up. We analyzed the independent risk factors associated with recurrent symptoms and complications during the last ARS. Statistical analysis was performed using GraphPad Prism^® and R software^®.

RESULTS

Seventy-three (7.49%) patients underwent redo-ARS during the last decade; 71 (98%) of the surgeries were performed using a minimally invasive approach. Forty-two (57.5%) had conversion from Nissen to Toupet. In 17 (23.3%) patients, the initial Nissen fundoplication was conserved. The initial Toupet fundoplication was conserved in 9 (12.3%) patients, and 5 (6.9%) had conversion of Toupet to Nissen. Out of the 73 patients, 10 (13%) underwent more than one redo-ARS. At 8.5 (1-107) months of follow-up, patients who underwent reoperation with Toupet ARS were less symptomatic during the postoperative period compared to those who underwent Nissen fundoplication (p = 0.005, OR 0.038). Patients undergoing mesh repair during the redo-fundoplication (21%) were less symptomatic during the postoperative period (p = 0.020, OR 0.010). The overall rate of complications (Clavien-Dindo classification) after redo surgery was 11%. Multivariate analysis showed that the open approach (p = 0.036, OR 1.721), drain placement (p = 0.0388, OR 9.308), recurrence of dysphagia (p = 0.049, OR 8.411), and patient age (p = 0.0619, OR 1.111) were independent risk factors for complications during the last ARS.

CONCLUSIONS

Failure of ARS rarely occurs in the hands of experienced surgeons. Redo-ARS is feasible using a minimally invasive approach. According to our study, in terms of recurrence of symptoms, Toupet fundoplication is a superior ARS technique compared to Nissen for redo-fundoplication. Therefore, Toupet fundoplication should be considered in redo interventions for patients who initially underwent ARS with Nissen fundoplication. Furthermore, mesh repair in reoperations has a positive impact on reducing the recurrence of symptoms postoperatively.

A Modified Technique to Create a Standardized Floppy Nissen Fundoplication Without a Bougie

INTRODUCTION

Nissen fundoplication is frequently applied in the surgical treatment of patients with gastroesophageal reflux disease (GERD). When the gastroesophageal junction remains too large or becomes too narrow, persistent GERD or dysphagia may occur. To assure a correct size of the gastroesophageal junction, the fundoplication can be created over a bougie. However, this increases the risk of esophageal perforation. Therefore, we have modified a previously described technique to create a standardized fundoplication without the use of a bougie. In this article, we describe this technique and demonstrate the initial results.

MATERIALS AND METHODS

We describe a technique to create a standardized Nissen fundoplication. After suture repair of the hiatal hernia, three marking sutures were placed on the gastric fundus, based on an equilateral triangle. The size of this triangle determines the final diameter of the fundoplication. With these measurements, we assure sufficient patency, minimize rotation, and create a more reproducible fundoplication that may reduce postoperative dysphagia.

RESULTS

We have operated 15 patients according to this technique. Mean operative time was 69.5 (SD 8.4) minutes, no complications occurred. There was no early dysphagia and the mean length of stay was 1.3 days (1-2). Quality of life after 1 year was excellent.

CONCLUSIONS

This modified method for standardized Nissen fundoplication is safe and might reduce postoperative dysphagia. Quality of life after 1 year is excellent. The effect on postoperative dysphagia and the reproducibility of this technique should be established in a large prospective study.

Laparoscopic revision surgery for gastroesophageal reflux disease

Laparoscopic antireflux surgery is a frequently performed procedure for the treatment of gastroesophageal reflux in surgical clinics. Reflux can recur in between 3% and 30% of patients on whom antireflux surgery has been performed, and so revision surgery can be required due to recurrent symptoms or dysphagia in approximately 3% to 6% of the patients. The objective of this study is to evaluate the mechanism of recurrences after antireflux surgery and to share our results after revision surgery in recurrent cases.From 2001 to 2014, revision surgery was performed on 43 patients (31 men, 12 women) between the ages of 24 and 70 years. The technical details of the first operation, recurrence symptoms, endoscopy, and manometry findings were evaluated. The findings of revision surgery, surgical techniques, morbidity rates, length of hospitalization, and follow-up period were also recorded and evaluated.The first operation was Nissen fundoplication in 34 patients and Toupet fundoplication in 9 patients. Mesh hiatoplasty was performed for enforcement in 18 (41.9%) of these patients. The period between the first operation and the revision surgery ranged from 4 days to 60 months. The most common finding was slipped fundoplication and presence of hiatal hernia during revision surgery. Revision fundoplication and hernia repair with mesh reinforcement were used in 33 patients. The other techniques were Collis gastroplasty, revision fundoplication, and hernia repair without mesh. The range of follow-up period was from 2 to 134 months. Recurrence occurred in 3 patients after revision surgery (6.9%). Although revision surgery is difficult and it has higher morbidity, it can be performed effectively and safely in experienced centers.

Reoperative antireflux surgery

Patient satisfaction with primary antireflux surgery is high, but a small percentage of patients experience recurrent reflux and dysphagia, requiring reoperation. The major anatomic causes of failed fundoplication are slipped fundoplication, failure to identify a short esophagus, and problems with the wrap. Minimally invasive surgery has become more common for these procedures. Options for surgery include redo fundoplication with hiatal hernia repair if needed, conversion to Roux-en-Y anatomy, or, as a last resort, esophagectomy. Conversion to Roux-en-Y anatomy has a high rate of success, making this approach an important option in the properly selected patient.

Modern medical and surgical management of difficult-to-treat GORD

Approximately 30-40% of patients taking proton pump inhibitors (PPIs) for presumed gastro-oesophageal reflux (GOR) symptoms do not achieve adequate symptom control, especially when no oesophageal mucosal breaks are present at endoscopy and when extra-oesophageal symptoms are concerned. After failure of optimization of medical therapy, a careful work up is mandatory that aims at determining whether symptoms are related to GOR or not. Most patients with refractory symptoms do not have GOR-related symptoms. Some may have symptoms related to weakly acidic reflux and/or oesophageal hypersensitivity. Baclofen is currently the only antireflux compound available as add-on therapy to PPIs, but its poor tolerability limits its use in clinical practice. There is room for pain modulators in patients with hypersensitive oesophagus and functional heartburn. Antireflux surgery is a suitable option in patients responding to medical therapy who want to avoid taking medication or if persisting symptoms can be clearly attributed to poorly controlled GOR.

Laparoscopic revision of failed antireflux surgery: a systematic review

BACKGROUND

Laparoscopic antireflux surgery is an accepted treatment for persistent gastroesophageal reflux but about 4% of patients will eventually require revision surgery.

METHODS

We searched The Cochrane Collaboration, Medline, and EMBASE databases, augmented by Google Scholar and PubMed related articles from January 1, 1990, to November 22, 2010. Twenty studies met the inclusion criteria, reporting on 930 surgeries.

RESULTS

The mean surgical duration was 166 minutes and conversion to open revision fundoplication was required in 7% of cases. Complications were reported in 14% of cases and the mean length of stay varied between 1.2 and 6 days. A good to excellent result was reported for 84% of surgeries and 5% of patients required a further revisional procedure.

CONCLUSIONS

Laparoscopic revision antireflux surgery appears to be feasible and safe, but subject to somewhat greater risk of conversion, higher morbidity, longer hospital stay, and poorer outcomes than primary laparoscopic fundoplication.

Anatomical failure following laparoscopic antireflux surgery (LARS): does it really matter?

INTRODUCTION

Failure rates of laparoscopic antireflux surgery (LARS) vary from 2-30%. A degree of anatomical failure is common, and the most common failure is intrathoracic wrap herniation. We have assessed anatomical integrity of the crural repair and wrap using marking Liga clips placed at the time of surgery and compared this with symptomatic outcome.

PATIENTS AND METHODS

A prospective study was undertaken on 50 patients who underwent LARS in a single centre over a 3-year period. Each had an X-ray on the first postoperative day and a barium swallow at 6 months at which the distance was measured between the marking Liga clips. An increase in interclip distance of > 25-49% was deemed 'mild separation', and an increase of > 50% 'moderate separation'. Patients completed a standardised symptom questionnaire at 6 months.

RESULTS

At 6 months' postoperatively, 22% had mild separation of the crural repair with a mean Visick score of 1.18, and 54% had moderate separation with a mean Visick score of 1.26. Mild separation of the wrap occurred in 28% with a mean Visick score of 1.21 and 22% moderate separation with a mean Visick score of 1.18. Three percent had mild separation of both the crural repair and wrap with a mean Visick score of 1.0, and 16% moderate separation with a mean Visick score of 1.13. Of patients, 14% had evidence of some degree of failure on barium swallow but only one of these was significant intrathoracic migration of the wrap which was symptomatic and required re-do surgery.

CONCLUSIONS

The prevalence of some form of anatomical failure, as determined by an increase in the interclip distance, is high at 6 months' postoperatively following LARS. However, this does not seem to correlate with a subjective recurrence of symptoms.

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.
