Surgical management of gastroesophageal reflux disease

Laparoscopic antireflux surgery or PPIs in the management of reflux-related esophageal stricture

BACKGROUND

Gastroesophageal reflux disease (GERD) is often associated with esophageal stricture, particularly benign esophageal stricture. We aimed to evaluate the effects of balloon catheter dilation (BD) combined with laparoscopic fundoplication (LF) surgery and proton pump inhibitors (PPIs) in patients with reflux-induced esophageal strictures.

METHODS

We retrospectively analyzed 116 patients with reflux-induced benign esophageal strictures who underwent balloon dilatation therapy combined with PPIs (BD-PPIs group, n = 58) and balloon dilatation combined with LF (BD-LF group, n = 58). Patients were followed up for 24 months. The outcomes of the patients were monitored, including clinical success, symptom improvement, adverse events, and the frequency of esophagitis.

RESULTS

At the latest follow-up, the rate of clinical success was higher in BD-LF group than in BD-PPIs group (80.4% vs. 57.7%, P = 0.011). The patients in the BD-PPIs group required more dilation sessions to achieve successful dilation, as compared to those in the BD-LF group (2.1 ± 1.2 vs. 0.7 ± 0.8, P < 0.001). The DeMeester score, number of reflux episodes for which pH was < 4, and lower esophageal sphincter pressure were significantly better in the BD-LF group than in the BD-PPIs group (all P < 0.001). The incidence of reflux esophagitis was higher in the BD-PPIs group than in the BD-LF group, at 24 months (58.8% vs. 18.2%, P = 0.003).

CONCLUSIONS

Balloon dilatation with concomitant LF is effective and safe for esophageal stricture secondary to GERD. Moreover, antireflux surgery techniques, such as Nissen or Toupet procedure, should be added for reflux-induced benign esophageal stricture.

Endoscopic cardial constriction with band ligation in the treatment of refractory gastroesophageal reflux disease: a preliminary feasibility study

BACKGROUND

Gastroesophageal reflux disease (GERD) is a common digestive disease, could cause extra-esophageal symptoms. Peroral endoscopic cardial constriction with band ligation (PECC-b) is a minimally invasive method for the treatment of GERD in recent years. The goals of this study were to evaluate the clinical efficacy of PECC-b to treat gastroesophageal reflux-related symptoms.

METHODS

A retrospective study of patients undergoing PECC-b between January 2017 and December 2018 at a single institution was conducted. All patients confirmed GERD by endoscopy, esophageal PH-impedance monitoring, esophageal manometry and symptom questionnaires. The outcome measures included reflux-related scores, patients' satisfaction and drug independence after 12 months following surgery.

RESULTS

A total of 68 patients, with follow-up of 12 months post surgery, were included in the final analysis. The symptom scores were all significantly decreased as compared with preoperation (P < 0.05). The esophageal symptom scores showed a better improvement than extra-esophageal symptoms (P < 0.001). Fifty-three (77.9%) patients achieved complete drug therapy independence and 52 (76.5%) patients were completely or partially satisfied with the symptom relief following surgery.

CONCLUSIONS

The PECC-b is a safe, effective and recommended approach for the control of GERD-related symptoms. Further multicenter prospective studies are required to confirm these outcomes.

Role of fundoplication in treatment of patients with symptoms of hiatal hernia

Gastroesophageal reflux disease (GERD) is often associated with hiatal hernia (HH). However, the need for fundoplication during hiatal hernia repair (HHR) remains controversial. The objective of this study was to evaluate the effect of HHR with concomitant laparoscopic Nissen fundoplication (HHR-LNF) in HH patients. A total of 122 patients with symptomatic HH were randomized to receive either HHR (n = 61) or HHR-LNF (n = 61). The measures of evaluating outcomes included DeMeester scores (DMS), complications, Reflux Diagnostic Questionnaire and patients' satisfaction 24 months following surgery. Despite comparable values in both groups at randomization, the DMS, total numbers of reflux episodes and percentage of time with pH < 4 were significantly higher in HHR group than in HHR-LNF group (P = 0.017, P = 0.002 and P = 0.019, respectively) at 6 months after surgery. One months postoperatively, complications were higher in the HHR-LNF group than in the HHR group (all P < 0.001), and there was no difference between the two groups at 6 months. By the end of the 2-year follow-up, HHR-LNF group showed a significantly lower reflux syndrome frequency-intensity score and greater percentage of satisfaction compared with HHR group (all P < 0.001). Laparoscopic HHR should be combined with a fundoplication in GERD patients with HH. HHR-LNF is safe and effective, not only improve reflux-related symptom, but also reduce the incidence of complications.

A Chinese randomized prospective trial of floppy Nissen and Toupet fundoplication for gastroesophageal disease

INTRODUCTION

To evaluate the clinical outcomes of laparoscopic floppy Nissen fundoplication (LNF) and laparoscopic Toupet fundoplication (LTF) for the treatment of gastroesophageal disease (GERD).

METHODS

A total of 84 patients with GERD were randomized to either LNF (n = 43) or LTF (n = 41) between January 2010 and January 2013. The primary endpoint measures were the DeMeester score, distal esophageal amplitude (DEA), peristaltic frequency, lower esophageal sphincter pressure (LESP), short-term and long-term postoperative dysphagia and recurrence rate. The secondary endpoints were improvements in symptom scores and quality of life (QoL), and perioperative complications.

RESULTS

LNF group had a lower DeMeester score and a higher LESP compared to LTF group after surgery (DeMeester score: P = 0.007; LESP: P = 0.027). The mean DEA and peristaltic frequency both improved significantly after surgery in 2 groups. There was no difference in the incidence of short-term adverse events (including dysphagia, heartburn, regurgitation et al.) between the two groups (P = 0.157). At the time of the latest follow-up, there was no difference in the incidence of symptomatic reflux symptom (heartburn and regurgitation) between the two groups (heartburn: P = 0.363; regurgitation: P = 1.000). A higher frequency of dysphagia was present in the LNF group compared with the LTF group (P = 0.023).

DISCUSSION

LNF is associated with an excessive elevation of LESP which may lead to further persistent dysphagia. Partial fundoplication may provide adequate reflux control, improve esophageal body motility and minimize complications associated with an 'over-tight' fundal wrap.

CONCLUSION

LTF seems to be as safe and effective on the long-term as LNF, but with a lower incidence of postoperative dysphagia (ChiCTR-TRC-13003945).

[Comparison of surgical patients with gastroesophageal reflux disease and Barrett's esophagus]

INTRODUCTION

Barrett's esophagus (BE) is the only known precursor of adenocarcinoma occuring in the lower third of the esophagus. According to statistics, severity and elapsed time of gastroesophageal reflux disease (GERD) are major pathogenetic factors in the development of Barrett's esophagus.

PATIENTS AND METHODS

In a retrospective study between 2001 and 2008, we compared the preoperative results (signs and sympthoms, 24 hour pH manometry, esophageal manometry, Bilitec) and treatment efficacy of 176 GERD patients and 78 BE patients, who have undergone laparoscopic Nissen procedure for reflux disease.

RESULTS

The two groups of patients had similar demographic features, and elapsed time of reflux sympthoms were also equal. Both groups were admitted for surgery after a median time of 1.5 years (19.87 vs. 19.20 months) of ineffective medical (proton pump inhibitors) treatment. Preoperative functional tests showed a more severe presence of acid reflux in the BE group (DeMeester score 18.9 versus 41.9, p < 0.001). On the other hand, mano-metry - despite confirming lower esophageal sphincter (LES) damage - did not show difference between the two groups (12.10 vs. 12.57 mmHg, p = 0.892). We did not experience any mortality cases with laparoscopic antireflux procedures, although in two cases we had to convert during the operation (1 due to extensive adhesions, and 1 due to injury to the spleen). 3 months after the procedure - according to Visick score - both groups experienced a significant decrease, or lapse in reflux complaints (group I: 73%, group II: 81% of patients), LES functions improved (17.58 vs.18.70 mmHg), and the frequency and exposition of acid reflux decreased (DeMeester score 7.73 vs. 12.72).

CONCLUSION

The severity of abnormal acid reflux occuring parallel with the incompetent function of the damaged LES triggers not only inflammation in the gastroesophageal junction (GEJ), but also metaplastic process, and the development of Barrett's esophagus. Laparoscopic Nissen procedure for reflux disease can further improve outcome among patients with GERD not responding to conservative therapy.
