"Redo" fundoplications: satisfactory symptomatic outcomes with higher cost of care

Minimally Invasive Roux-en-Y Gastric Bypass for Fundoplication failure offers Excellent Gastroesophageal Reflux Control

Roux-en-Y gastric bypass (RYGB) may represent a superior alternative to reoperative fundoplication in patients with symptomatic failure. Our goal was to assess early outcomes of patients after RYGB for failed fundoplication. Records of patients who underwent fundoplication takedown and RYGB from March 2007 to June 2013 were reviewed for demographics, comorbidities, operative findings, and perioperative outcomes. Data are reported as medians (range). Forty-five patients who had undergone 64 prior antireflux procedures (range, one to three fundoplications) were identified. Median patient age was 56 years (range, 25 to 72 years) with a body mass index of 33 kg/m2 (range, 22 to 51 kg/m2). Most patients had comorbidities: hypertension (60%), anxiety/ depression (44.4%), dyslipidemia (33.3%), asthma (31%), obstructive sleep apnea (26.7%), arthritis (22.2%), and diabetes (11.1%). Median symptom-free interval was 3 years (range, 0 to 25 years). All patients had an anatomic reason for failure: 83 per cent had a hiatal hernia and 35 per cent had a slipped Nissen fundoplication. The procedures were accomplished laparoscopically in 28, robotically in 13, and open in four cases. Median operative time was 367 minutes (range, 190 to 600 minutes) and estimated blood loss averaged 100 mL (range, 25 to 500 mL). Five patients (11%) required reoperation: one for an anastomotic leak, one for anastomotic obstruction, and three for early obstruction resulting from adhesions. Two patients developed respiratory failure requiring prolonged mechanical ventilation. Length of stay averaged four days (range, 1 to 33 days) with two readmissions: one for melena and one for vomiting and dehydration; neither required intervention. There was no mortality. At 11 months of follow-up (range, 2.3 to 54 months), 93.3 per cent of patients were symptom-free. When primary fundoplication for gastroesophageal reflux disease fails, fundoplication takedown and RYGB can be accomplished safely with minimally invasive techniques. The conversion to a RYGB has an acceptable perioperative morbidity and excellent early symptom control, and, therefore, should be considered for reoperative patients gastroesophageal reflux disease.

The risk of mortality following secondary fundoplication in a population-based cohort study

BACKGROUND

Mortality following laparoscopic fundoplication has been found to be negligible. However, some patients require secondary fundoplication, and the risk of mortality following such procedure is scarcely studied.

METHODS

This nationwide Swedish population-based cohort study included all patients undergoing secondary fundoplication following primary laparoscopic fundoplication in 1997 to 2013, regardless of indication. Primary outcome was mortality within 90 days of surgery, and secondary outcome was postoperative length of hospital stay.

RESULTS

A total of 9,765 patients underwent primary laparoscopic fundoplication, 540 (5.5%) patients underwent secondary fundoplication. About 382 (70.7%) were conducted laparoscopically, and 158 (29.3%) were conducted with an open technique. No deaths occurred within 90 days of the secondary fundoplication. Median length of stay was longer following secondary fundoplication (4.8 days, interquartile range 1.0 to 5.0 days), compared to primary laparoscopic fundoplication (2.5 days, interquartile range 1.0 to 3.0 days).

CONCLUSIONS

This population-based cohort study indicates that secondary fundoplication following primary laparoscopic fundoplication is a safe procedure. The longer hospital stay following secondary fundoplication compared to primary laparoscopic fundoplication is likely explained by the higher rate of open surgical approach.

Imaging findings of successful and failed fundoplication

Postoperative imaging findings contribute to the diagnosis of successful and failed fundoplication procedures. Gastroesophageal reflux disease, a common illness in the United States, is primarily treated medically but may require surgery if there are persistent symptoms or reflux complications despite medical treatment. Laparoscopic Nissen fundoplication has become the most used and successful surgical antireflux procedure since its introduction in 1991. Radiologists should understand the anatomy of the esophagogastric junction, antireflux and esophageal protective mechanisms, and preoperative radiologic findings that contribute to selection of the surgical technique, as well as the most commonly used antireflux operations and their indications. Barium examination and computed tomography of the thorax and abdomen play an important role in the follow-up of patients with gastric fundoplication, including evaluation of surgical effectiveness and detection and characterization of postoperative complications. Failed fundoplications are classified into six types: tight Nissen, incompetent repair, disruption of the wrap, stomach slippage above the diaphragm, slipped Nissen, and transdiaphragmatic wrap herniation. Classification is based on radiologic visualization of the obstructed esophageal lumen, recurrence of gastroesophageal reflux, integrity and location of the gastric wrap, stomach slippage, and recurrence of hiatal hernia. Imaging findings are useful in detecting complications, providing anatomic information to identify the cause of surgical failure, and selecting appropriate medical or surgical management.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

A Single Institution's Experience and Journey with over 1000 Laparoscopic Fundoplications for Gastroesophageal Reflux Disease

There have been great advances in laparoscopic surgery for gastroesophageal reflux disease (GERD), including laparoendoscopic single-site (LESS) surgery. This study details our experience with over 1000 patients undergoing fundoplication for GERD and the journey therein. A total of 1078 patients have been prospectively followed after fundoplication. Patients scored the frequency/severity of symptoms using a Likert scale (0 = never/not bothersome to 10 = always/very bothersome). We compared the outcomes of the first and last 100 patients. Median data are reported. Of 1078 patients, 943 underwent conventional laparoscopic fundoplication and 135, most recently, underwent LESS fundoplication. Before fundoplication, patients noted frequent/severe symptoms (e.g., heartburn: frequency = 8, severity = 8). Fundoplication ameliorated frequency/severity of symptoms (e.g., heartburn: frequency = 2, severity = 0; less than preoperatively, P < 0.05). Relative to our first 100 patients, patients after LESS surgery had similar symptom control (e.g., heartburn: frequency = eight to two vs eight to zero, severity = eight to one vs six to one) but had shorter hospital stays (2 vs 1 day, P < 0.05) and had no apparent scars. Laparoscopic fundoplication provides durable and efficacious treatment for GERD; long-term symptom resolution and patient satisfaction support its continued application. The advent of LESS surgery advances surgeons’ abilities to provide safe and salutary care while promoting cosmesis.

Update on fundoplication for the treatment of GERD

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

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

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

PATIENTS AND METHODS

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

RESULTS

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

CONCLUSION

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

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.

Trends and perioperative outcomes of inpatient antireflux surgery in the United States, 1993-2006

Antireflux surgery is an effective treatment for gastroesophageal reflux disease, but postoperation complications and durability may be problematic. The objective of the study was to determine whether inpatient antireflux surgery continued to decline in the United States due to concerns about its long-term effectiveness and the popularity of gastric bypass surgery and to assess recent changes in its perioperative outcomes. Using the Nationwide Inpatient Sample, we identified adult patients undergoing inpatient antireflux surgery during 1993-2006 and compared the trends of inpatient antireflux surgery with inpatient gastric bypass surgery. Perioperative complications included laceration, splenectomy, transfusion, esophageal dilation, total parenteral nutrition, and infection. Inpatient antireflux surgery increased from 9173 in 1993 to 32 980 in 2000 (+260%) but then decreased to 19 668 in 2006 (-40%). Compared with 2000, patients undergoing inpatient antireflux surgery in 2006 were older (49.9 ± 32.4 vs. 54.6 ± 33.6 years) and had a longer length of stay (3.1 ± 10.0 vs. 3.7 ± 13.4 days), more complications (4.7% vs. 6.1%), and higher mortality (0.26% vs. 0.54%) (all P < 0.05). Compared with inpatient gastric bypass surgery, length of stay was longer and mortality was higher for inpatient antireflux surgery in 2006, but neither was significant controlling for age. In 2006, perioperative outcomes of inpatient antireflux surgery were better in high-volume hospitals (all P < 0.01). Inpatient antireflux surgery continued to decline in the United States from 2000 to 2006, concomitant with a dramatic increase in inpatient gastric bypass surgery. Older patient age and worsening perioperative outcomes for inpatient antireflux surgery suggest increased medical complexity and possibly a larger share of reoperations over time. Designating centers of excellence for antireflux surgery based on local expertise may improve outcomes.

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.
