Reoperative antireflux surgery for dysphagia

International Society for Diseases of the Esophagus consensus on management of the failed fundoplication

Fundoplication is a durable, effective, and well-accepted treatment for gastroesophageal reflux disease. Nonetheless, troublesome postoperative symptoms do occasionally occur with management varying widely among centers. In an attempt to standardize definition and management of postfundoplication symptoms, a panel of international experts convened by the Guidelines Committee of the International Society for Diseases of the Esophagus devised a list of 33 statements across 5 domains through a Delphi approach, with at least 80% agreement to establish consensus. Eight statements were endorsed for the domain of Definitions, four for the domain of Investigations, nine for Dysphagia, nine for Heartburn, and four for Revisional surgery. This consensus defined as the treatment goal of fundoplication the resolution of symptoms rather than normalization of physiology or anatomy. Required investigations of all symptomatic postfundoplication patients were outlined. Further management was standardized by patients' symptomatology. The appropriateness of revisional fundoplication and the techniques thereof were described and the role of revisional surgery for therapies other than fundoplication were assessed. Fundoplication remains a frequently-performed operation, and this is the first international consensus on the management of various postfundoplication problems.

Determination of causes of post-operative dysphagia after anti-reflux surgery based on intra-operative planimetry

INTRODUCTION

Dysphagia after anti-reflux surgery (ARS) is one of the most common indications for re-operative anti-reflux surgery and a leading cause of patient dissatisfaction. Unfortunately, the factors affecting its development are poorly understood. We investigated the correlation between pre-operative manometric and the intra-operative impedance planimetry (EndoFLIP™) measurements and development of post-operative dysphagia.

METHODS

A review of patients who underwent index robotic ARS in our institution. Patients who underwent pre-operative manometry and intra-operative EndoFLIP™ were included in our study. Dysphagia was assessed pre-operatively and at 3-month after surgery.

RESULTS

Fifty-five patients (26.9%) reported post-operative dysphagia, and 34 (16.6%) reported new or worsening dysphagia. On pre-operative manometry, patients with post-operative dysphagia had a lower distal contractile integral [868.7 (IQR 402.2-1447) mmHg s cm vs 1207 (IQR 612.1-2111) mmHg s cm, p = 0.006) and lower esophageal sphincter (LES) pressure [14.7 IQR (8.9-23.6) mmHg vs 20.7 IQR (10.2-32.6) mmHg, p = 0.01] compared to those without post-operative dysphagia. They were also found to have higher pre-operative cross-sectional surface area (CSA) [83 IQR (44.5-112) mm2 vs 66 IQR (42-93) mm2, p = 0.02], and distensibility index (DI) [4.2 IQR (2.2-5.5) mm2/mmHg vs 2.9 IQR (1.6-4.6) mm2/mmHg, p = 0.003] compared to patients without post-operative dysphagia. Additionally, the decrease in CSA [- 34 (- 18.5, - 74.5) mm2 vs - 26.5 (- 10.5, - 53.7) mm2, p = 0.03] and DI [- 2.3 (- 1.2, - 3.7) mm2/mmHg vs - 1.6 (- 0.7, - 3.3) mm2/mmHg, p = 0.03] measurements were greater in patients with post-operative dysphagia.

CONCLUSION

Patients who developed dysphagia post-operatively had poorer pre-operative motility and a greater change in LES characteristics intra-operatively. This finding suggests the utility of pre-operative manometry and intra-operative EndoFLIP in identifying patients at risk of developing dysphagia post-operatively.

Percentage of intrathoracic stomach predicts operative and post-operative morbidity, persistent reflux and PPI requirement following laparoscopic hiatus hernia repair and fundoplication

PURPOSE

Large hiatus hernias are relatively common and can be associated with adverse symptoms and serious complications. Operative repair is indicated in this patient group for symptom management and the prevention of morbidity. This study aimed to identify predictors of poor outcomes following laparoscopic hiatus hernia repair and fundoplication (LHHRaF) to aid in counselling potential surgical candidates.

METHODOLOGY

A retrospective analysis was performed from a prospectively maintained, multicentre database of patients who underwent LHHRaF between 2014 and 2020. Revision procedures were excluded. Hernia size was defined as the intraoperative percentage of intrathoracic stomach, estimated by the surgeon to the nearest 10%. Predictors of outcomes were determined using a prespecified multivariate logistic regression model.

RESULTS

625 patients underwent LHHRaF between 2014 and 2020 with 443 patients included. Median age was 65 years, 62.9% were female and 42.7% of patients had ≥ 50% intrathoracic stomach. In a multivariate regression model, intrathoracic stomach percentage was predictive of operative complications (P = 0.014, OR 1.05), post-operative complications (P = 0.026, OR 1.01) and higher comprehensive complication index score (P = 0.023, OR 1.04). At 12 months it was predictive of failure to improve symptomatic reflux (P = 0.008, OR 1.02) and persistent PPI requirement (P = 0.047, OR 1.02). Operative duration and blood loss were predicted by BMI (P = 0.004 and < 0.001), Type III/IV hernias (P = 0.045 and P = 0.005) and intrathoracic stomach percentage (P = 0.009 and P < 0.001). Post-operative length of stay was predicted by age (P < 0.001) and emergency presentation (P = 0.003).

CONCLUSION

In a multivariate regression model, intrathoracic stomach percentage was predictive of operative and post-operative morbidity, PPI use, and failure to improve reflux symptoms at 12 months.

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

BACKGROUND:

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

AIMS:

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

METHODS:

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

RESULTS:

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

CONCLUSIONS:

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

Redo fundoplication and early Roux-en-Y diversion for failed fundoplication: a 3-year single-center experience

BACKGROUND

Redo fundoplication (RF) and Roux-en-Y diversion (RNY) are both accepted surgical treatments after failed fundoplication. However, due to higher reported morbidity, RNY is more commonly performed only after several surgical failures. In our experience, RNY at an earlier point of the disease progression seems to be related with better outcomes. The aim of this study was to investigate this aspect by comparing the results between RF and RNY performed by a single surgeon over 3 years at our institution.

METHODS

A prospectively maintained database was reviewed to identify patients who underwent RF or RNY at our institution between 2016 and 2019 by a single surgeon (author SKM). Patients with previous bariatric surgery were excluded.

RESULTS

Of 43 patients, 28 underwent RF and 15 underwent RNY (mean body mass index 28.6 and 32.7 kg/m², respectively, p = 0.01). The number of previous antireflux surgeries for the RF and RNY groups was 1 (82% vs 80%, p > 0.99), 2 (18% vs 7%, p = 0.4), and more than 2 (0% vs 13%, p = 0.1). RNY took longer than RF (median, 165 vs 137 min, p = 0.02), but both groups had a median estimated blood loss of 50 ml (p = 0.82). There was no difference in intraoperative complications (25% vs 20% for RF and RYN, respectively, p > 0.99). Postoperative complications were more common in the RF than in the RYN group (21% vs 7%, p = 0.39). Median hospital stay was 3 days for both groups (p = 0.78). At short-term follow-up, the mean quality of life score was similar for the RF and RYN groups (11.5 vs 12.2, p = 0.8).

CONCLUSIONS

RNY diversion, if performed by experienced hands and at an earlier point of disease progression, has comparable perioperative morbidity to RF and should be considered as a feasible and safe option for definitive treatment of failed antireflux surgery.

Comparative Analysis of Patients with Robotic Hiatal Hernia Repairs with and without Collis Gastroplasty

INTRODUCTION

After extensive mediastinal dissection fails to achieve adequate intra-abdominal esophageal length, a Collis gastroplasty(CG) is recommended to decrease axial tension and reduce hiatal hernia recurrence. However, concerns exist about staple line leak, and long-term symptoms of heartburn and dysphagia due to the acid-producing neoesophagus which lacks peristaltic activity. This study aimed to assess long-term satisfaction and GERD-related quality of life after robotic fundoplication with CG (wedge fundectomy technique) and to compare outcomes to patients who underwent fundoplication without CG. Outcomes studied included patient satisfaction, resumption of proton pump inhibitors (PPI), length of surgery (LOS), hospital stay, and reintervention.

METHODS

This was a single-center retrospective analysis of patients from January 2017 through December 2018 undergoing elective robotic hiatal hernia repair and fundoplication. 61 patients were contacted for follow-up, of which 20 responded. Of those 20 patients, 7 had a CG performed during surgery while 13 did not. There was no significant difference in size and type of hiatal hernias in the 2 groups. These patients agreed to give their feedback via a GERD health-related quality of life (GERD HRQL) questionnaire. Their medical records were reviewed for LOS, length of hospital stay (LOH), and reintervention needed. Statistical analysis was performed using SPSS v 25. Satisfaction and need for PPIs were compared between the treatment and control groups using the chi-square test of independence.

RESULTS

Statistical analysis showed that satisfaction with outcome and PPI resumption was not significantly different between both groups (P > .05). There was a significant difference in the average ranks between the 2 groups for the question on postoperative dysphagia on the follow-up GERD HRQL questionnaire, with the group with CG reporting no dysphagia. There were no significant differences in the average ranks between the 2 groups for the remaining 15 questions (P > .05). The median LOS was longer in patients who had a CG compared to patients who did not (250 vs. 148 min) (P = .01). The LOH stay was not significantly different (P > .05) with a median length of stay of 2 days observed in both groups. There were no leaks in the Collis group and no reoperations, conversions, or blood transfusions needed in either group.

CONCLUSION

Collis gastroplasty is a safe option to utilize for short esophagus noted despite extensive mediastinal mobilization and does not adversely affect the LOH stay, need for reoperation, or patient long-term satisfaction.

Salvage Options for Fundoplication Failure

PURPOSE OF REVIEW

Gastroesophageal reflux disease (GERD) affects millions of people worldwide. Many patients with medically refractory symptoms ultimately undergo antireflux surgery, most often with a laparoscopic fundoplication. Symptoms related to GERD may persist or recur. Revisional surgery is necessary in some patients.

RECENT FINDINGS

A reoperative fundoplication is the most commonly performed salvage procedure for failed fundoplication. Although redo fundoplication has been reported to have increased risk of morbidity compared with primary cases, increasing experience with the minimally invasive approach to reoperative surgery has significantly improved patient outcome with acceptable resolution of reflux symptoms in the majority of patients. Recurrence of reflux symptoms after an initial fundoplication requires a thorough work-up and a thoughtful approach. While reoperative fundoplication is the most common procedure performed, there are other options and the treatment should be tailored to the patient, their history, and the mechanism of fundoplication failure.

[Report of 12 years experience in the surgical treatment of 286 paraesophageal hernias]

BACKGROUND

In contrast to axial hiatus hernias, paraesophageal hernias are rare but can lead to chronic iron deficiency anemia and severe acute complications. Treatment is manifold and consistent standards are lacking.

OBJECTIVES

The aim of this study was to describe our experiences of 286 patients with paraesophageal hernias, who underwent surgery from 2003 to 2014 at a tertiary referral center. The study was particularly concerned with morbidity, mortality, quality of life and recurrence rates.

MATERIAL AND METHODS

In 12 years a total of 286 paraesophageal hernias were surgically treated, 255 with a minimally invasive procedure and 31 with an open approach. In 138 patients (48 %) the suture-based hiatoplasty was reinforced by means of a lightweight mesh, which was fixed with fibrin glue in 90 cases. Abdominal fixation of the stomach consisted of a gastropexy and anterior (n = 244) or posterior (n = 42) fundoplication.

RESULTS

Complications arose in 8.4 % of the patients. The mean hospital stay was 5.3 (± 2.8) days for elective surgery and 24.7 (± 17.8) days for emergency operations. The gastrointestinal quality of life index according to Eypasch significantly increased from mean preoperative values of 92.8 (± 22.5) to 109.6 (± 20.2) in the postoperative course (p < 0.001). Of the patients 20 (7 %) suffered a recurrence requiring surgery, including 7 early and 13 late recurrences. During the immediate postoperative period radiographically detected recurrences were promptly revised. The strategy of late recurrences in the long-term course was based on patient symptoms and asymptomatic hernias were treated conservatively while symptomatic hernias were surgically treated. Symptomatic late recurrences developed in 4.6 % of the patients, including 7.4 % (11 out of 148) without and 1.4 % (2 out of 138) with primary mesh repair.

CONCLUSION

The repair of paraesophageal hernias in 286 patients provided excellent patient satisfaction and symptom improvement with low perioperative morbidity and mortality. Mesh reinforcement reduced the recurrence rate. The quality of life index is a suitable clinical course parameter for evaluation of paraesophageal hernias.

Long-term outcomes of reintervention for failed fundoplication: redo fundoplication versus Roux-en-Y reconstruction

BACKGROUND

Redo fundoplication (RF) is the mainstay of treatment for failed fundoplication. A subset of patients with failed fundoplication requires Roux-en-Y reconstruction (RNY) for symptom relief. The aim of this study was to compare the long-term subjective outcomes between RF and RNY in patients with failed fundoplication.

METHODS

After Institutional Board Review approval, retrospective review of a prospective database identified 119 RF (mean = 54.1 years, 78 women) and 64 RNY (mean = 54.8 years, 35 women) patients who underwent reoperative surgery between December 2003 and September 2009. Data variables analyzed included demographics, esophageal manometry, 24-h pH study, type of procedure, perioperative findings, complications, pre- and postoperative symptom (heartburn, regurgitation, dysphagia, and chest pain) scores (scale 0-3), and patient satisfaction score (scale 1-10). Patients with grade 2 and 3 scores were considered to have significant symptoms.

RESULTS

Patients who underwent RNY had a significantly higher body mass index, higher mean number of risk factors, and higher preoperative severity of heartburn and regurgitation compared to the RF group. Of the 183 patients, long-term (>3 years) follow-up was available for 132 (89 RF and 43 RNY) patients. Symptom severity significantly improved after both procedures, with the exception of dysphagia in the RNY group. Overall, there was no significant difference in patients' satisfaction between the RF and RNY groups. In subset analysis, patients with morbid obesity, esophageal dysmotility, or ≥4 risk factors have better satisfaction with RNY compared to RF (p = 0.027, 0.031, and 0.045, respectively).

CONCLUSIONS

RF and RNY have equally good patient satisfaction at 3 years follow-up. RNY may have improved outcomes in patients who are morbid obese, have esophageal dysmotility, or have four or more risk factors.

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.
