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.

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.

378 REDO LAPAROSCOPIC FUNDOPLICATON IN A PATIENT WITH WRAP MIGRATION FOLLOWING TWICE FAILED NISSEN FUNDOPLICATION

Re-operation for wrap failure is a complex procedure required in 3–6% of patients. This video demonstrates a successful laparoscopic redo fundoplication in a patient who had previously undergone laparoscopic Nissen's fundoplication twice for GERD in another institution, first for GERD in 2014 and then for recurrence of reflux. Patient presented to us with dysphagia and regurgitation. The work-up revealed wrap migration into the right pleural cavity. A successful redo laparoscopic Toupet fundoplication was performed. Methods The video describes the procedure of laparoscopic re do fundoplication. Results Patient is doing well at a follow up of 16 months. Conclusion Re-do laparoscopic fundoplication can be successfully accomplished through laparoscopic approach. Video https://drive.google.com/file/d/1Perelnr0fwGIk1kiAexYvXnJY01cO98C/view?usp=sharing.

Peculiarities of surgical treatment of patients with gastroesophageal reflux disease

Objective. To analyze the effectiveness of various methods of laparoscopic antireflux operations in patients with gastroesophageal reflux disease. Materials and methods. The results of treatment of 177 patients with gastroesophageal reflux disease from 2015 to 2021 were analyzed. Patients were divided into three groups: 1st - 62 patients who underwent laparoscopic antireflux surgery of our own modification (Patent of Ukraine No 59772); 2nd - 91 patients who underwent laparoscopic Nissen fundoplication; 3rd - 24 patients who underwent laparoscopic Toupet fundoplication. Results. 36 months after surgery in the 1st group the recurrence rate of gastroesophageal disease was 1.6%, recurrence of hernia of the esophageal orifice - 1.6%, in the 2nd group - 7.7 and 3.3%, respectively; in the 3rd group - 12.5 and 8.3%, respectively. Conclusions. The application of a new integrated approach to the surgical treatment of gastroesophageal reflux disease reduces the number of postoperative complications (gas -bloat syndrome - 3 times, dysphagia - 5 times), the recurrence rate of gastroesophageal reflux disease - 5 times and recurrence of esophageal hernia - 2 times, improves the quality of life of patients 36 months after surgery in 2.6 times and increases the timeliness of diagnosis and facilitates the choice of differentiated treatment tactics.

P169 COMPARISON OF LAPAROSCOPIC TOUPET FUNDOPLICATION AND MAGNETIC SPHINCTER AUGMENTATION IN PATIENTS WITH 3-5 CM HIATUS HERNIA

Aim To compare quality of life in patients with large hiatus hernia undergoing laparoscopic Toupet fundoplication and magnetic sphincter augmentation. Background and Methods Laparoscopic Toupet fundoplication (LTF) and laparoscopic magnetic sphincter augmentation (MSA) have been compared in a previous retrospective study (Asti E et al, Medicine, 2016) in patients with small hiatal hernia (<3 cm). There is no universal consensus in the use of MSA in patients with large hiatus hernia. This is an observational, retrospective, comparative cohort study. Patients with <3 cm or >5 cm hiatus hernia measured by endoscopy and barium swallow study and those with previous esophago-gastric surgery were excluded. The primary outcome was quality of life based on the Gastro-Esophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) questionnaire. Secondary outcomes were proton pump inhibitors (PPI) use, incidence of dysphagia and gas-related symptoms, and hiatus hernia recurrence rate. Results Between March 2007 and June 2018, 150 patients with GERD met the inclusion criteria; 88 underwent a LTF and 62 a MSA procedure. Both groups had similar preoperative features. The mean follow-up was 64 months and all patients were followed for at least one year after surgery. There was no statistically significant difference between LTF and MSA in GERD-HRQL scores (p=0.178), PPI use (p=0.327), gas-related symptoms (p=0.162), dysphagia (p=0.254), and reoperation rate (p=0.167). Conclusion Both LTF and MSA have similar safety profile and disease-specific quality of life in patients with large hiatal hernia.
