653 LAPAROSCOPIC TOUPET FUNDOPLICATION RARELY INFLUENCES THE DECLINE IN FEV1 SEEN AFTER LUNG TRANSPLANT

Lung allografts have the shortest survival of any solid organ transplant. The leading cause of chronic lung allograft dysfunction (CLAD) is bronchiolitis obliterans syndrome (BOS). The aetiology of BOS remains poorly understood, with infections, immunosuppression and gastro-oesophageal reflux disease (GORD) amongst the proposed co-factors. A recent systematic review of GORD and BOS examined six retrospective case series with relatively small numbers and conflicting results. Our dataset is the largest cohort reported to date. Methods Retrospective review of a prospectively maintained database containing 149 consecutive lung transplant recipients undergoing laparoscopic Toupet fundoplication. A single expert surgeon (>5000 procedures) with published high-quality long-term outcomes in the non-transplant population did the operations. All were referred with symptoms of GORD and/or positive 24-hour ambulatory pH study. FEV1 was measured at three time points before (6, 3 and 1 month) and after (3, 6 and 12 months) surgery. Data were analysed using random intercept generalised linear (mixed) models to examine changes in FEV1 across time, as well as graphical methods (least squares method for FEV1 trendlines and two-tailed t-test). Results Median age was 56 (IQR 44–66) years; 84/149 were male. 132 had bilateral sequential single lung transplantation. The underlying pathologies were representative—emphysema, cystic fibrosis, interstitial lung disease. 8 patients died within 6 months of fundoplication. Using a linear mixed model there was no significant change in FEV1 across time after surgery compared with the last pre-operative measurement (p = 0.48). A significant reduction in FEV1 was seen in those undergoing fundoplication after CLAD was diagnosed (1.47 L, 95% CI 1.21–1.72, p < 0.001). There was no change in trajectory of FEV1 when trendlines for each patient were analysed (p = 0.777). Conclusion As with any solid organ transplant, lung allografts unfortunately suffer failure with time. Laparoscopic Toupet fundoplication performed in a high-volume centre by an experienced surgeon did not appear to alter this. In particular, once CLAD is diagnosed it seems that the decline in function (FEV1) is accelerated and cannot be salvaged by fundoplication. A minority of patients had their declining FEV1 stabilised or improved by surgery, but it is not yet possible to predict response.

74 LAPAROSCOPIC MANAGEMENT OF A PULSION EPIPHRENIC OESOPHAGEAL DIVERTICULUM SECONDARY TO ACHALASIA.

This is a video submission of a laparoscopic resection of an epiphrenic oesophageal pulsion diverticulum secondary to achalasia. A Heller’s cardiomyotomy is also performed together with a Toupet fundoplication. Methods The patient is a 40 year old woman with a 12 month history of worsening dysphagia, reflux symptoms, as well as occasional regurgitation of food, worse at night. Barium swallow showed a distal oesophageal diverticulum and oesophageal manometry confirmed type 1 achalasia. Upper GI endoscopy showed no other intra-luminal findings. Results The patient underwent a laparoscopic resection of the diverticulum, together with a Heller’s cardiomyotomy and Toupet fundoplication. There were no post-operative complications. She remains well and asymptomatic at 9 month follow-up. Conclusion Pulsion diverticula secondary to achalasia are a known but rare entity. A few variations exist on how to manage this condition surgically, especially with respect to the type of fundoplication. We present our preferred technique for dealing with this condition.

178 RANDOMIZED CONTROLLED TRIAL COMPARING ANGLE OF HIS ACCENTUATION WITH TOUPET FUNDOPLICATION IN PATIENTS UNDERGOING LAPAROSCOPIC HELLERS MYOTOMY: INTERIM RESULTS

Laparoscopic Heller’s Cardiomyotomy (LHCM) is the surgical treatment of choice for achalasia. Addition of an antireflux procedure is recommended to reduce the postoperative reflux. However, there is no consensus regarding the ideal antireflux procedure. In an earlier study we have shown that Angle of His accentuation (AOH) is similar to Dor fundoplication. In this study we present the interim results of an RCT comparing AOH with Toupet fundoplication as an adjunct to LHCM. Methods Patients of Achalasia cardia presenting after October 2017 were randomised to receive either AOH or Toupet following Heller cardiomyotomy based on computer generated random sequence. Primary outcome was incidence of post-operative symptomatic reflux and esophagitis on endoscopy. Secondary outcome was relief of dysphagia and Achalasia specific health related Quality of life assessment (ASHRQoL). Symptom scores for dysphagia, regurgitation and heartburn as well as ASHRQoL were noted pre operatively and at 3 monthly intervals. Objective evaluation was done using timed barium swallow, Upper GI endoscopy and oesophageal manometry. Data was recorded on excel spreadsheet and analysis done using SPSS v5. Results A total of 52 patients (25 Toupet, 27 AOH) were included in the analysis. All patients were successfully operated laparoscopically with no conversions, intraoperative perforations or perioperative mortality. The mean operative duration was 128 min in the AOH group and 146 min in the Toupet group (p < 0.05). There was significant improvement in symptom scores as well as objective parameters in both groups with no difference between the 2 groups at a mean follow-up of 6 months (5-9 months; Table 1). 3 patients in AOH group (11%) and 4(16%) patients had new onset reflux with esophagitis in 2 patients in each group. Conclusion AOH is technically easier and can be performed in a shorter time. The symptom relief is similar in both groups with similar incidence of heartburn and esophagitis in the short term. A longer follow up is recommended in a larger number of patients.

633 CONVERSION TO TOUPET FUNDOPLICATION WITH DISTAL GASTRECTOMY AND ROUX-EN-Y GASTROJEJUNOSTOMY AFTER FAILED NISSEN FUNDOPLICATION

Laparoscopic Nissen Fundoplication fails in almost 15% of patients and most of them must be re-operated in order to improve reflux symptoms, esophagitis, or hiatal hernia. Surgical options are to redo LNF, distal gastrectomy alone or combination of both procedures. Redoing LNF, is associated with high rate of postoperative complications and re-failure. Purpose To present the early and medium-term postoperative outcomes of patients submitted to Laparoscopic Toupet Fundoplication combined with Distal Gastrectomy with Roux-en-Y gastrojejunostomy. Methods prospective study including 23 patients submitted to Laparoscopic Nissen Fundoplication who presented recurrence of gastroesophageal reflux after the operation. They were studied with endoscopy, barium swallow, manometry and 24 h pH monitoring in order to determine presence of esophagitis, anatomical deformities, defective Lower Esophageal Sphincter and pathologic acid reflux. Surgical process consisted on re-establishing the anatomy of the esophago-gastric junction, and then perform laparoscopic Toupet fundoplication combined with distal gastrecvtomy and Roux Y gastrojejunostomy. Results After surgery statistically significant improvement regarding heartburn (p < 0.0001), dysphagia (p < 0.0001) and retrosternal chest pain (p < 0.0001) as well as in the endoscopic esophagitis was observed. No significant LES pressure increase after the operation was observed. (from 7.88 + 2.7 to 10.5 + 3.36) (p = 0.15), but the abnormal acid reflux improved significantly after the reoperation, %time pH < 4 decreases from 12.00 + 6.62 to 4.3 + 4.04 (0.0004) and DeMeester score from 44.82 + 21.8 to 11.95 + 5.14 (0.0008) respectively. Conclusion The proposed procedure is safe option to treat successfully patients after failed Nissen fundoplication. Reflux symptoms, esophagitis, presence oh hiatal hernia and reflux score improved after the procedure.

REVIEW OF 5 YEARS RESULTS AFTER SURGERY FOR GASTRO-OESOPHAGEAL REFLUX DISEASE: NISSEN VS TOUPET

INTRODUCTION Multiple studies attempt to demonstrate the superiority of Toupet fundoplication over the classic Nissen technique in the treatment of gastro- oesophageal reflux disease (GERD). In our study we compared the results of both techniques. MATERIAL AND METHODS A retrospective descriptive study of patients operated because of GERD using laparoscopic Nissen and Toupet fundoplication in our centre between January 1, 2015 and December 31, 2019. RESULTS 80 patients were operated, 56 Nissen (70%) versus 24 Toupet (30%). Both groups are comparable in terms of mean age, distribution by sex, obesity, toxic habits, the prevalence of typical symptoms, DeMeester, and presurgical lower oesophagal sphincter pressure; although there are differences regarding the presence of associated hiatal hernia and within them the type. A similar surgical time (136.59 vs 132.71 minutes) and mean stay (4.02 vs 5 days) were observed. In the Nissen group, 12 patients (21.42%) presented initial postoperative dysphagia, requiring 2 endoscopic dilations and 5 reoperations, compared to 5 patients (20.83%) in the Toupet group, that did not require dilation and with 1 reoperation. The conversion and mortality rate was 0% in both groups, with a variable follow-up of 22.08 versus 14.45 months. CONCLUSIONS Both techniques present similar results, including the rate of postoperative dysphagia, which is one of the most feared complications. However, it would be necessary to increase the size and longer follow-up to establish long-term results.

RefluxStopTM, a novel device to address gastroesophageal reflux disease: Short-term results

Objective To report safety, feasibility, and patient’s functional short-term outcome of novel RefluxStop anti reflux operation. Methods All patients (n = 20) who received laparoscopic implantation of the RefluxStop device from September 2018 to November 2020 in a university hospital were included for retrospective analysis. Incidence of adverse device-effects and procedure-related adverse events are reported as safety endpoints. Feasibility was assessed reporting operation duration, rate of conversion to open surgery and technically correct position of the device by control radiography during patient’s follow up. Subjective (Gastroesophageal Reflux Disease - Health Related Quality of Life (GERD-HRQL) - questionnaires; after 6 weeks and every six-month thereof) and objective data (24h-pH-manometry, barium swallows and upper endoscopies) are reported as functional outcome parameters. Comparison between values at baseline versus post-procedure follow-up are performed using the paired samples T-test, if appropriate. Results Median follow up was 4 (1 – 22) month. Three out of 20 patients had previous upper gastrointestinal surgery (EndoStim implantation). No serious adverse device related events occurred. One patient with dysphagia required balloon dilatation at the oesophageal gastric junction 4 weeks postoperatively. Median duration of surgery was 85 (59-188) minutes. There was no conversion to open surgery. There was significant reduction in the mean of total GERD-HRQL score at baseline compared to 6-weeks after surgery with 23.9 and 4.3 (p < 0.001) as well as at baseline and 6 month after surgery with 28.4 and 6.8 (p = 0.021), respectively. At 6 weeks follow up, all of the subjects had over 50% improvement of the GERD-HRQL score compared to baseline. One patient with acceptable device positioning developed symptom recurrence and received conversion to laparoscopic Toupet fundoplication after 10 months. Conclusion RefluxStop procedure seems to be a safe operation with promising short-term results. For high-level recommendation, further studies looking for long-term results and randomized comparisons to the standard anti reflux procedures like Nissen or Toupet fundoplication are required.

Severe Referred Shoulder Pain Following Revision Fundoplication From a Stich on the Diaphragm

Complications following fundoplication surgery for hiatal hernias are rare. Herein, we present the case of a 61-year-old woman who underwent a Nissen fundoplication, complicated by dysphagia, and a revision modified Toupet fundoplication for a hiatal hernia, after which she began to experience severe prandial referred left shoulder pain that was refractory to medical management. We hypothesized that a diaphragmatic suture placed during the revision fundoplication could be the source of the pain, and we elected to remove the suture, resulting in resolution of the pain. This pain remained resolved at the most recent follow-up on postoperative week six, and the patient had no further concerns.
