V-OG01 Minimally invasive oesophagectomy: Technique of linear stapled anastomosis

Background Several anastomotic techniques have been described when performing an oesophagectomy. Each technique has its own merits and drawbacks. The stapled side to side technique creates a widely patent anastomosis with low stricture rate. Methods This video highlights the technique adopted and developed over the last 5 years. There are several key steps that need to be adhered to, to create a reliable, robust and reproducible anastomosis. These include the orientation of the oesophagus during transection, the use of mucosal retaining sutures, the use of a 34 bougie for the oesophagotomy and the correct retraction of the conduit when performing the anastomosis. Results The anastomosis was successfully performed without complications. Check endoscopy revealed a widely patent secure join. The anastomosis typically now takes 15–18 minutes. At the end of the procedure, the conduit cap was buried under the pleura and the anastomosis wrapped in omental fat. The patient was discharged on day 10 on a low residue diet. Conclusions This technique has been adopted and developed over the last 5 years. It has proved reliable and reproducible with a low stricture rate and a very low leak rate. It is easier to perform than a total hand sewn anastomosis and permits visualisation of the luminal oesophagus prior to anastomosis.

P601 Are Inflammatory Bowel Disease patients’ expectations met by dietetic services?

Background Guidelines recommend that Inflammatory Bowel Disease (IBD) patients should have access to specialised dietitian support. Literature suggests that patients are often dissatisfied with their access to reliable nutrition information and dietitian services. Our aim was to assess whether New Zealand (NZ) dietetic services were meeting the expectations of patients. Methods In early 2020 an electronic survey to explore experience of dietetic services was disseminated to approximately 2000 patients (and parents) by Crohn’s and Colitis NZ and IBD health professionals. Quantitative responses were analysed via non-parametric methods and qualitative responses were analysed via inductive analysis. Results Responses were received from 407 IBD patients. Participants were asked if it ‘is useful for patients diagnosed with IBD to have access to a dietitian for nutrition advice?’ with 86% responding ‘Yes’ and 12% ‘Maybe’. Almost all (95%) patients had nutrition topics that they would like to discuss with a dietitian but only 52% had seen a dietitian and 45% had never been referred. Patients were interested in various nutrition topics (Table 1). Most (65%) would like access to a dietitian whenever a new nutrition issue arises. The most frequent nutrition advice received was to follow a specific diet, most commonly a low fermentable carbohydrate diet followed by a low residue diet, or general nutrition advice. Two-thirds (66%) of respondents found the dietitian advice at least moderately useful while 18% reported it was not at all useful. Patients who saw a dietitian in a private clinic were more likely to find the advice useful (p=0.0001), as were those who had received written advice (p<0.0001). Common themes in response to open-ended questions included: frustration at difficulty accessing dietetic services; desire for routine dietitian referral at diagnosis and ongoing access; the need for dietitians to have specialist knowledge of IBD; a perception that some medical staff believe nutrition is not relevant in IBD management. Conclusion Many patients have never been referred to a dietitian and a proportion of patients did not find dietitian advice useful. Dietitian advice appears to be on the topics most commonly of interest to patients. Access to dietetic services needs to improve and exploration is needed to elucidate why some aspects of services are not meeting patient expectations.

A132 ENDOSCOPIC ULTRASOUND-GUIDED GASTROENTEROSTOMY USING A NOVEL DOUBLE BALLOON DEVICE IN THE MANAGEMENT OF MALIGNANT GASTRIC OUTLET OBSTRUCTION

Background EUS-gastroenterostomy (EUS-GE) is a novel modality in the management of malignant gastric outlet obstruction (MGOO). It is, however, technically challenging limiting its widespread application. To facilitate EUS-GE, a double balloon catheter has been developed in Japan. While this tool is not available outside of Asia, we have conceived a similar device using a widely available vascular balloon catheter. We aim to determine the clinical efficacy and safety of EUS-GE using this double balloon device (DBD). Aims We aim to determine the clinical efficacy and safety of EUS-GE using this double balloon device (DBD). Methods This is a single-centre, retrospective study of consecutive patients who underwent DBD assisted EUS-GE for MGOO from January 2019-June 2020 (IRB approved). The DBD consists of two 60 mm vascular balloons (Coda, Cook Medical, USA) fashioned together with the balloons 10 cm apart (Figure 1). It is inserted across the obstruction over a wire to the ligaments of Treitz. Both balloons are then inflated followed by saline and contrast infusion into the occluded small bowel segment to facilitate EUS-guided insertion of a 15 mm cautery assisted lumen apposing metal stent (AxiosTM, Boston Scientific Inc, USA). The primary endpoint is the rate of technical success defined as adequate deployment of the stent. Secondary endpoints include rate of clinical success and adverse events. Results A total of 11 patients were included in this study. 45% were female with a mean age of 64.9 ± 8.6 years old. The etiology of MGOO was 73% pancreatic cancer, 9% gastric cancer, 9% duodenal cancer, and 9% metastatic cervical cancer. Procedures were performed under general anesthesia and conscious sedation in 82% and 18%, of patients respectively. The mean procedure time was 64.8 ± 25.8 minutes. Technical and clinical success (intention to treat) was 91%. The only technical failure was due to poor patient tolerance of the procedure under conscious sedation. There was one adverse event (9%) due to stent migration rated as severe. Two patients (18%) required re-intervention for stent obstruction secondary to food impaction associated with non-compliance to a low-residue diet. Following re-enforced instructions, no further obstruction occurred. All patients started a clear liquid diet within 1 day of the procedure with a mean time to a low residue diet of 3.25 days ± 2.5. The median length of hospital stay following the procedure was 5 days ± 13. The median follow-up time was 84 days (IQR 152). Conclusions DBD assisted EUS-GE is clinically effective and safe. This balloon device may greatly facilitate the technical aspect of EUS-GE while potential enhancing its safety and clinical use. Larger studies are needed to validate this approach to EUS-GE.
