Virtual Educational Channel

 

 

• Virtual Global interactive Staff Meetings around a clinical case

 

The constraints of the worldwide Covid-19 pandemic require OESO to adapt its educational structure.

A new initiative responds to this need: the OESO-SEMPIRE VIRTUAL EDUCATIONAL CHANNEL.

 

It is built on the basis, already operational, of the OESO-SEMPIRE Platform

coordinating the educational activities of a network of Pilot Centers of Excellence in Esophagology worldwide.

 

Like many of the previous ones, this approach is original, multi-disciplinary, and, from the outset, global.

Its implementation is made possible by use of the virtual techniques of communication available today.

 

Each time, one of the Pilot centers will propose a challenging clinical case open for interactive discussion, followed by the commentary of an invited expert.

The topic and time will be announced well in advance on the OESO website, with specification of the time to allow connection at a comfortable hour of the day.

 

 

Join us,

for an innovative series of international "Staff meetings" with experts from the five parts of the world.

 

The OESO-SEMPIRE virtual channel will welcome, in addition to the Pilot Centers of the network
able to connect, the contribution of

• all the members of OESO,
• other renowned specialists bringing their specific knowledge into the network, whatever their discipline,
• and, more widely, members of the international scientific community.

 

 

• Setting up a meeting

Specifications:

• Transmitted from one of the Pilot Centers of the OESO-SEMPIRE Platform.
• Intended for Pilot Centers in another part of the world, taking into account the time differences.
• Chaired by the Scientific Director of the Center with a member of the junior faculty.
• Short duration: 1-2 hours.

 

Content:

• Presentation of a challenging case in esophagology, preferably involving several disciplines,
  – Exchange of views between the presenters,
  – Discussion with people connected in another part of the world with their audience
     (prior announcements made by the Centers to encourage attendance).
• Invited commentary given by an internationally recognized expert who can also contribute his/her experience to the panel discussion.
  These experts don't have to belong to the OESO-SEMPIRE network.

 

Technology:

• Zoom type technology,
• with announcement well in advance requiring prior signing up of potential participants.
• Courses and discussions recorded and available on the OESO website.

 

• Time zones                                                                                          > Chart download pdf

Didactic presentation

Pepsin: molecular pathophysiology and diagnostic utility

Tina Samuels, MS, Program Manager

Gastroesophageal and extraesophageal reflux are prevalent and costly diseases. Recognition of the pathogenicity of nonacid reflux has stimulated interest in alternatives to acid-targeting diagnostics and therapeutics. Pepsin is the most deleterious enzyme in refluxate, eliciting inflammatory and carcinogenic effects irrespective of acid. Its presence in all refluxate and detection in saliva have situated pepsin as the most widely researched biomarker for reflux today. A summary of the emerging findings regarding pepsin-mediated damage during reflux and developments in pepsin-targeting diagnostics will be presented.

 

 

Didactic presentation

Fosamprenavir for the treatment of Laryngopharyngeal Reflux (LPR)

Nikki Johnston, PhD

Given the paucity of data supporting efficacy of acid-suppression therapy for laryngopharyngeal reflux (LPR), the America Gastroenterology Association recommends against its use in the absence of classic gastro-esophageal reflux disease (GERD) symptoms. With compelling evidence of nonacid proximal reflux of pepsin and its association with laryngeal and pharyngeal symptoms and endoscopic findings, a new treatment which specifically targets pepsin could be of great value. Fosamprenavir was found to bind to and inhibit pepsin, abrogating pepsin-mediated laryngeal inflammation and mucosal damage in an LPR mouse model. Fosamprenavir has a good safety profile, is well-tolerated, and targets a foreign virus, making it an ideal drug to repurpose/reformulate, allowing a more expeditious and limited safety assessment in a clinical trial compared to a new molecule. Furthermore, this new approach would be amenable to local treatment of readily accessible airways affected by LPR allowing lower dosing, limiting systemic side effects. FDA/IND approval has been obtained for a 12-week, randomized, placebo-controlled, double-blind, phase III clinical trial to assess the efficacy of oral fosamprenavir for the treatment of LPR. Safety, tolerability, and pharmacokinetic parameters of fosamprenavir administered by dry powder inhaler is also being assessed.

Case 4:

 

Presenter: Prof. Serhat Bor

Chair, Department of Gastroenterology, Ege University, School of Medicine, Izmir, Turkey

 

27 year old female referred for the evaluation of anti-reflux surgery

 

She has been suffering because of heartburn, acid regurgitation and especially hoarseness daily for three years. She wakes up with heartburn and cough.

PPI response is less than 50% for all symptoms.

There is no alarm symptom. Upper gastrointestinal Endoscopy shows LA-A esophagitis.

24 h MII-pH monitoring shows “weak acid reflux”. SAP and SI are negative.

High resolution esophageal manometry is normal.

The patient is also consulted by Psychiatry. She diagnosed with somatisation disorder.

Her strong desire for the antireflux surgery was discusssed during the reflux team meeting and refused. She was put on alginate. She refused the neuromodulators at the beginning but convinced. Amitryptillin 10 mg was started and increased to 20 mg. She is in a much better situation now.

Topic: Esophageal cancer in young patients

Subtheme: a celebration of the first fellowship between two Pilot Centers of the OESO-SEMPIRE Platform

The discussion will be based around two cases

 

Presentation of the cases: Dr Matthew Read and Prof Russell E. White

 

​Case 1: a 23-year-old man, originally from East Africa, recently presented to St Vincent’s Hospital in Melbourne with a four-month history of chest tightness, progressive dysphagia and headache. This was subsequently investigated with endoscopy which revealed a cancer at the GEJ. Subsequent staging excluded metastatic disease.

 

​               

​Figure 1                                                   ​Figure 2                                              ​Figure 3

 

Figure 1: Endoscopic images detailing the GEJ from above

Figure 2: Endoscopic images detailing the GEJ from below

Figure 3: FDG PET avid lesion at the GEJ

 

 

Case 2: a 16-year-old male patient presented with an eight-month history of progressive dysphagia, anorexia, and weight loss.

 

• Despite multiple visits to health facilities and being treated for a range of different ailments, no endoscopy was performed until seven months later.
• There were no associated risk factors, no history of smoking and no alcohol intake. There was also no significant family history of cancer.
• Histology revealed a moderately differentiated adenocarcinoma.
• Following surgery, the patient made a good recovery. However, they subsequently developed an anastomotic stricture which required serial dilatation. During the post-operative period they also required treatment for a bowel obstruction secondary to a band adhesion.
• Patient developed suicidal ideation in association with a major depressive illness and is currently receiving psychotherapy (12 sessions to date).

 

Discussion points:

• What challenges exist in the diagnosis & management of esophageal cancer in the younger patient.
• Balancing care, quality of life and survivorship. How to tailor the best approach.
• How do cancers between a younger patient and an older patient compare? Are they different entities and should we be more aggressive with our management?
• Management of esophageal cancer in a resource limited environment.
• Highlighting the significance of the first fellowship between OESO Pilot centers.

The discussion will also include the following presentations:

• Surgery for cancer of the GEJ. How I do it. Dr. Yong Li, Thoracic Surgeon of the Beijing National Cancer Center, China.
• Clinicopathological features of GEJ cancer of the younger patient. Assoc Prof Qin Huang, Harvard Medical School / Brigham and Women’s Hospital, Boston.

 

 

Panel for discussion:

• Michael Mwachiro (Program Director, Tenwek)
• Dr Guifang Xu, GI Gastroenterologist of Nanjing Drum Tower Hospital, China
• Dr Lei Wang, GI Gastroenterologist of Nanjing Drum Tower Hospital, China
• Dr Yong Li, Thoracic Surgeon of the Beijing National Cancer Center, China
• Assoc Prof Qin Huang, Harvard Medical School, Boston
  
  

Registration is free, but mandatory:

 

The next clinical case coming up for discussion will be proposed in May by the Pilot Center of Stanford.

Date and details on time will be announced on the OESO website and in next Newsletters.

​Case 1

Immunotherapy-induced pneumonia following neo-adjuvant chemoradiation plus PD-1 inhibitor in a patient with locally advanced esophageal squamous cell carcinoma.

 

A 61-year-old female with a lesion at the lower thoracic esophagus found by gastroscopy in routine check-up. – Squamous cell carcinoma confirmed by biopsy.

 

Presentation of the case: Hong Yang – Zerui Zhao (Guangzhou)

 

• EUS and contrast CT scan showed a cT2N1 locally advanced esophageal squamous cell carcinoma.
• Normal respiratory function and diffusion capacity.

 

The patient signed a consent for participation in a phase II trial (NCT04006041) on feasibility of combination of Toripalimab (PD-1 inhibitor) and neoadjuvant chemoradiation in esophageal cancer.

 

• Chemoradiation on April 1st, 2021, with

          – 44 Gy in 20 fractions over 4 weeks.

          – 4 cycles of Paclitaxel with Cisplatin carried out weekly simultaneously.

          – 2 doses of PD-1 inhibitor on day 1 and day 22 during the same time.

• Re-do EUS showed tumor shrinkage, but the subcarinal lymph node
  (endo-bronchial ultra-sound guided needle aspiration) suggested the existence of several atypical cells tumor metastases suspected.

• Minimally invasive McKeown esophagectomy performed about 8 weeks following completion of neoadjuvant treatment.
• The pathological report showed a pathological complete response with no evidence of tumor in both primary tumor and resected lymph nodes.

 

The development of pulmonary dysfunction required mechanical ventilation during the first postoperative week, but the symptoms of dyspnea did not remiss following antibiotic treatment. Besides, only mild elevation of white blood cells and procalcitonin was found by several blood tests. A CT scan carried out on postoperative day 15 showed bilateral lung effusion and pneumonia.

Hence, the multi-disciplinary team specialists in our Institute suggested that the patient might be experiencing immunotherapy induced pneumonia.

• Administration of Prednisolone / 10 days resulted in significant remission of the pneumonia showed by CT scan on postoperative day 25.

 

The patient was discharged on postoperative day 27 and recovered uneventfully in the out-patient visit 6 months after surgery.

Case 2

Removal of an esophageal foreign body penetrating into the mediastinum by minimally invasive transcervical mediastinoscopy-assisted approach

 

Background

Ingestion of foreign bodies, especially animal bones, is one of the most common endoscopic emergencies, especially in China. Foreign bodies can be fishbones, pills, capsules, bottle lids and even false teeth. Fortunately, most of them can be easily be removed by skilled endoscopists, thanks to the development of endoscopic techniques. Only 1% or less require surgery, including foreign bodies with sharp-ends which penetrate the esophageal wall, causing esophageal perforations and remaining in the mediastinum space. The perforating esophageal foreign bodies may cause severe complications, including bleeding and migration.

 

Traditional approach can be surgery through cervical skin incision. However, for foreign bodies which penetrate in the thoracic esophagus (more than 20 cm from incisors), cervical approach may not be effective and surgery through the chest wall would be inevitable.

In our case, instead of a traditional transcervical approach, we tried a novel, minimal invasive approach with the help of a mediastinoscope.

 

A 65-year-old woman swallowed a fishbone 10 hours before she was admitted to our hospital with substernal pain.

 

Presentation of the case: Lijie Tan – Zongwei Chen (Shanghai)

 

• CT scan and EUS showed upper-thoracic esophageal perforation caused by a foreign body, the distal end being at the level of aortic arch.

 

The foreign body was located outside the esophageal wall and was adjacent to the upper edge of the aortic arch.

• A transparent cap was attached to the front of the endoscope, showing a longitudinal ulcer, about 0.8 cm/length, 20 cm from the incisors.
• A hook knife was used to cut the esophageal wall along the damaged area, and to expose the submucosal and muscular layers.
  In spite of careful examination, no foreign body was found.
• After hemostasis with hot biopsy forceps, the wound was closed with clips.

 

Surgery was therefore needed.

The patient was placed in supine position under general anesthesia with bilateral lung ventilation.

 

• A 5cm incision was made about 1cm lateral to the SCM.
• A lap-protector (FF00707 Hakko Co Ltd, Japan) with matched retractor (Hakko Co Ltd, Japan), each pre-inserted with three E-Z Trocars
• (5-70mm Short Hakko Co Ltd, Japan), was inserted into the cervical incision.
• ​Carbon dioxide was insufflatted at a pressure of 8mmHg into the mediastinum to enlarge the very limited mediastinal surgical field, and VISERA ELITE II System OTV-S300 with deflectable laparoscope (Olympus Corporation, Tokyo Japan) was used as mediastinoscope to ensure the maximal surgical view for the operator.
• The operator first inserted a LigasureTM Maryland Jaw sealer (Medtronic) held in the right hand into the upper mediastinum under endoscopic vision, and then inserted a suction stick (which also acted as a retractor) held in the left hand set into the upper mediastinum to provide counter traction on the operative field and remove smoke produced by Ligasure.
• Mobilization of the upper thoracic esophagus was then performed, starting from the left and posterior side of the esophagus.
• The tip of the fishbone was found in the mediastinum before reaching the aortic arch, and a dissecting forceps was used to remove the whole fishbone from the mediastinum.
• The incision was closed after a drainage tube was placed in the surgical field.

 

Discussion

For most cases of esophageal foreign bodies, a gastroscope is effective. However, once penetrating the esophageal wall, the foreign body cannot be found by gastroscope, and surgery is needed.

In this case, referring to mediastinoscope and laparoscope-assisted esophagectomy, we used the minimally invasive transcervical approach with the help of a deflectable laparoscope to remove the foreign body in the mediastinal space

 

Preoperative workup is crucial, to investigate the location of the foreign body as to the surrounding important tissues and organs or arteries.

Previous reports demonstrated that CT was useful for a precise, definitive diagnosis of an esophageal foreign body, or when complications were suspected.

CT should be performed again before surgery, because of the risk of migration of the foreign body following the previous maneuvers such as EUS, or movements of the patient.

A disabling case of GERD after esophagectomy

 

A 48 year old female with history of heartburn and episods of dysphagia for 30 years.

46 Kg, 160 cm (BMI 17 Kg/m²)

 

• HRM (July 2015) Type 2 achalasia.
  – 2 sessions of endoscopic dilation: improvement of symptoms, gained 5 Kgs. During the last session, identification of a superficial, 18mm lesion on mid third of the esophagus.
  – Pre-operative workup: T1 squamous cell tumor.
  – Endoscopic removal planned in June 2015, but failed, due to submucosal fibrosis precluding submucosal dissection.

 

• Ivor Lewis procedure performed on July 2016 by laparoscopy and thoracoscopy approach.
  – Pathology: T1 N0 R0 squamous cell cancer.
  – Postoperative course complicated by gastroparesis which delays oral feeding.
  – Patient discharged on POD 17.

 

• October 2016: suffers from repeated vomits, necessitating a naso-gastric tube.
  – Endoscopy shows a large gastric ulcer at the site of the staple line.
  – Endoscopic dilation of the pylorus.
  – Oral feeding stopped and replaced by enteral nutrition by jejunostomy which falls 2 months later.

 

• January 2017: weight is 45 Kg (+ 2 Kg).
  – Endoscopy shows a persistent ulcer with negative biopsies.
  – Oral feeding is still very difficult,
  – Endoscopic submucosal pylorotomy performed with poor clinical results.

 

• March 2017: weight is 34 Kg.
  – Naso gastro duodenal tube placed for nutrition.
  – Enteral feeding associated with a clinical improvement.

 

• May 2017: weight is 45 Kg.
  – Oral feeding possible but still uncomfortable.
  She complains of vomiting, reflux and coughing at night. Healing of gastric ulcer.
  
  

• March 2018: duodenal diversion performed, with uneventful postoperative course.

 

• Two months later, stable weight at 44 Kg
  – oral feeding possible and sufficient,
  – but still regurgitations and episodes of vomits.
  The nutritional status does not improve, due to persistent difficulties for feeding.
  
  

•  June 2020: jejunostomy: 1 liter of enteral nutrition each night, and 3 meals per day.
  
  
•  July 2021, weight is 49 Kgs, with normal oral feeding.
  
  
•  Removal of the jejunostomy planned for December 2021.

 

Conclusion: severe gastroparesis after Ivor Lewis procedure in a patient who suffered from Type 2 achalasia.

 

Duodenal diversion performed by our team in similar, but less severe situations in 9 patients.

This time, duodenal diversion did not meet our expectations.

Gist of the Case:

Presentation of the case:

• Stéphane Bonnet (IMM)
• Nicole Faermark (IMM)

 

A 68-year-old patient, with intermittent dysphagia to liquids and solids,

painful thoracic spasms and intermittent vomiting. Loss of weight around 15 kg.

 

Diagnosis process:

• CT scan: 5cm long circumferential thickening of the mid thoracic esophagus.
• Endoscopy: pseudo tracheal aspect of the esophagus («trachealization») with multiple rings and no peristalsis.
• Biopsies: normal without eosinophilic esophagitis.
• PET/CT: suspicious 12cm long esophageal fixation (SUV max 15,6).
• Echo-endoscopy: thickening and fusion of wall layers, 36 to 39cm from dental arch.
• High-resolution manometry: impaired relaxation of LES, pan esophageal pressurization pattern.

 

Therapeutic process:

• After multidisciplinary discussions,
  a first series of Botox injections was performed with slight beneficial effect on pain.
• ​Considering the atypical outcome,
  a new echo-endoscopy was performed showing a corkscrew aspect of the esophagus and a pseudo diverticulization between 30 to 42cm from dental arch.
•  Following a new board discussion,
  a myotomy, achieved by thoracoscopic approach in prone position, was performed.

 

Follow-up: Six months later, the patient eats normally, with no pain, and is gaining weight.

 

Discussion points: the difficult problems of diagnostic and therapeutic approach regarding atypical dysphagia.

• Pre-treatment imaging and endoscopic workup and its interpretation,
• Choice of management (endoscopic or surgical approach),
• Long-term results.

 

​Discussion led by Brice Gayet and Stéphane Bonnet, IMM, Paris

with a top level panel currently being assembled.

3rd meeting:

Saturday, October 3, 2020

 

Hosted by Russel White and Michael Mwachiro

From Tenwek Hospital (Bomet, Kenya)

 

Multidisciplinary Panel for discussion:

Matthew Read (Melbourne) – Kumwinder Dua (Milwaukee) 

• Time: 7-9 am EAT (East African Time, GMT+3)

• Zoom technology applied
• Zones in a comfortable time to connect to the meeting:

 

Gist of the Case:

An unusual case of a 6 year old female involving a foreign body lodged in the esophagus for an extended period of time. The case required a multidisciplinary approach between surgeons and endoscopists to provide appropriate initial care for the patient, and for the complications which arose.

 

The patient complained of a persistent cough of at least three months duration. She had a chest radiograph performed which revealed the presence of a foreign body in the oesophagus at the level of the tracheal carina. Neither she nor her mother recalled the incident of ingesting the foreign body. The child was able to tolerate a normal diet without difficulty. She did not appear to be in any significant distress, but did have a persistent cough.

 

Upper GI endoscopy revealed a metallic foreign body, firmly wedged in the mid-esophagus. There appeared also to be a trachea-esophageal fistula present in the anterior surface of the esophagus.

 

Discussion points, with a panel of experts:

• What would you do with this patient?
• What would be your therapeutic strategy?
• How would you proceed surgically?
