Endoscopy-assisted laparoscopic intragastric resection of early gastric cancer
In the minimally invasive approach to a gastric pathology, the association of laparoscopy with endoscopy (also called hybrid or collaborative surgery) emerges as an advanced therapeutic option for the surgical treatment of both benign and malignant intragastric lesions in selected patients.
We present the case of an elderly patient aged 86 with a serious medical history. She is endoscopically diagnosed with a gastric lesion located in the incisura angularis with a biopsy of high-grade dysplasia/carcinoma “in situ”.
Given the patient's age and her medical history, the multidisciplinary committee decided to perform a minimally invasive surgery. Submucosal dissection of the lesion using a hybrid approach (intragastric endoscopy/laparoscopy) was proposed.
The pathological area was marked and stained by endoscopy, followed by intragastric submucosal dissection with laparoscopic instruments assisted by means of endoscopy.
The surgery went smoothly and the patient could be discharged 48 hours after surgery.
Final pathological findings reported a well-differentiated tubular adenocarcinoma infiltrating the lamina propria and surgical resection margins free of tumor infiltration (pT1a Nx Mx (TNM 8th Ed. 2017)).

Endoscopic sleeve gastroplasty (ESG): live educational procedure with resolution of device-related complication
Endoscopic sleeve gastroplasty (ESG) is a novel endobariatric procedure with a mechanism of action totally different from the one used for a standard sleeve gastrectomy. An over-the-scope suturing system (OverStitch™, Apollo Endosurgery, Austin, TX) mounted on a dual-channel gastroscope (GIF- 2TH180, Olympus, Center Valley, PA) allowed to place full-thickness sutures in order to obtain gastric volume reduction and shrinking. The number of applied sutures relies on the gastric volume. Sutures are placed starting from the incisura to the fundus that is spared in a U-shaped fashion. A tissue-retracting helix device is used to grab the gastric wall. In this live educational video, Professor Silvana Perretta presented the case of a morbidly obese 38-year-old female patient with a BMI of 36.72kg/m2.
The procedure was performed with the patient under general anesthesia and carbon dioxide insufflation. An Overtube™ (Apollo Endosurgery, Austin, TX) was placed at the beginning of the procedure to protect the airways, the esophagus, and the hypopharynx. Each purse-string suture consisted of 6 to 8 full-thickness bites starting first on the anterior gastric wall, then on the greater curvature, and the posterior wall and moving backward in the opposite direction. Once completed, the suture was tied and knotted using a cinching device (EndoCinch™). During the live procedure, a complication occurred due to an excessive pressure placed on the EndoCinch™ handle which caused a break of the collar part of the cinch. The management of this complication was achieved by cutting the suture, so that the collar part of the cinch which grasped the mucosa could be detached with a grasper to allow for suture replacement. A total of 4 sutures were applied in order to obtain gastric tubulization.

Case studies of complicated surgical scenarios
In this short presentation, Professor Yen-I Chen, MD, expert in advanced endoscopy and pancreaticobiliary disease at McGill University (Montreal, Canada), introduces 3 video cases of complicated surgical scenarios which were managed endoscopically.
In the first video, he presents the case of a 58 year-old man with a previous history of pancreatic cancer (2016). The patient had had a pancreaticoduodenectomy (Whipple procedure). After 2 years, the patient presented cancer recurrence with septic cholangitis due to gastrojejunostomy obstruction (closed loop obstruction of the afferent limb and also loop obstruction of the efferent limb).
In the second video, Prof. Chen looks into what can go wrong during endoscopic ultrasound-guided gastrojejunostomy. Previous stent systems required dilatations prior to stent deployment, and here, the video presents a case scenario in which the stent was displaced causing gastric perforation in the abdominal cavity. This complication was managed using a NOTES procedure.
In the third video, he reports the case of a patient with a previous obstructed duodenal stent which required an endoscopic ultrasound-guided gastrojejunostomy using the Axios stent.

Endoscopic Submucosal Dissection (ESD) of the rectum for a large rectal polypoid lesion: a live educational procedure
Endoscopic Submucosal Dissection (ESD) is an endoscopic technique which allows ‘en bloc’ resection of early stage tumors and polyps in the gastrointestinal tract. In this case, Professor Yahagi presents the case of a 67-year-old male patient with an incidental finding of a large rectal polyp during an MRI study. Colonoscopy revealed a 5cm laterally spreading tumor granular type (LST-G) of the rectum, extending to one fourth of the rectal circumference. The ESD was performed with a dual channel gastroscope in retrovision due to the proximity of the LST-G to the anal verge. Glycerol and indigo carmine were injected into the submucosal plane to lift the target lesion. The mucosal incision followed by submucosal dissection was performed with a 1.5mm DualKnife™ (Olympus) using a swift coag electrosurgical setting. Hemostasis of large vessels was performed switching to the forced coag effect. The vascular submucosal network has been carefully assessed. All critical steps are evaluated during the procedure.

All you need to know to perform an ERCP for biliary stones extraction: live procedure
An 82-year-old man underwent an emergency endoscopic retrograde cholangiopancreatography (ERCP) for acute cholangitis secondary to choledocholithiasis 11 days earlier. At that time, since the patient was under Clopidogrel, the sphincterotomy was not performed and a plastic stent was released in the common bile duct (CBD) to bypass the stones. In this live procedure, Dr. Boškoski performs an ERCP with sphincterotomy and biliary stones extraction. During the procedure, the operator gives every fundamental tips and tricks to perform the correct procedure. At the end of the intervention, a 3D cholangiography is performed to confirm complete biliary stones extraction.

Endoscopic sleeve gastroplasty (ESG): live procedure
In this live procedure, Professor Perretta performs an endoscopic sleeve gastroplasty (ESG) using the OverStitch™ endoscopic suturing system (Apollo Endosurgery) in a 50-year-old obese male patient (with a BMI of 35.3). In this particular case, preoperative esophagogastroduodenoscopy (EGD) showed a Barrett’s esophagus with positive histology for intestinal metaplasia, which is not a contraindication for this kind of endoscopic intervention. ESG is performed with the patient under general anesthesia and carbon dioxide insufflation. The supine position is preferred because it is safer than the left lateral decubitus position as it allows for a better exposure of the stomach. Sutures are placed in a U-shaped fashion from the incisura angularis to the fundus, which is spared using the OverStitch™ suturing system, mounted on a double channel Olympus scope. The system allows for the placement of durable full-thickness stitches to obtain gastric volume reduction and shrinking.

Peroral endoscopic myotomy of a suspected type III achalasia with a double scope control
A 59-year-old woman was referred to our unit for progressive dysphagia and chest pain associated with heartburn and chest fullness. A nutcracker esophagus was suspected at the HD manometry and the patient was scheduled for a peroral endoscopic myotomy (POEM). The procedure started with an esophagogastroduodenal series (EGDS), which showed abnormal contractions of the distal esophagus and increased resistance at the level of the esophagogastric junction (EGJ) with a high suspicion of type III achalasia. The tunnel was started 12cm above the EGJ in a 5 o’clock position. After submucosal injection, a mucosal incision was made with a new triangle-tip (TT) knife equipped with water jet facility. The access to the submucosa was gained and a submucosal longitudinal tunnel was created until the EGJ, dissecting the submucosal fibers with the TT knife. The myotomy was performed by completely dissecting the circular muscular layer muscle fibers using swift coagulation. To assess the extension of the myotomy just at the level of the EGJ, a “double scope control” was performed by inserting a pediatric scope, which confirmed the presence of the mother scope light in the esophagus. The submucosal tunnel and the myotomy were then extended together for 1 to 2cm. A second check with the pediatric scope showed the presence of the mother scope light in the correct position above the EGJ. The mucosal incision site was finally closed using multiple endoclips.

Once the Overtube™ was placed, the scope equipped with the OverStitch™ (Apollo Endosurgery®, Austin, Tex) suturing device was inserted through the stomach, and the suturing was initiated at the level of the incisura. The tissue-retracting helix device was used to grab the stomach wall, allowing for full-thickness bites. Each suture consisted of multiple sequential U-shaped bites along the anterior wall, the greater curvature, the posterior wall, and then in the opposite direction. Once completed, the suture was tied and knotted using a cinching device. Three sutures were applied in order to obtain gastric tubulization, and to spare the fundus.

Endoscopic mucosal resection (EMR) of multiple hyperplastic polyps of the stomach
A 69 year-old man with a history of hypertension, type 2 diabetes, and renal insufficiency underwent a gastroscopy for chronic anemia. During this procedure, a 3cm hyperplastic gastric polyp was discovered. The patient was scheduled for endoscopic submucosal dissection (ESD). The procedure started with a gastroscopy, which showed a normal duodenum and many gastric hyperplastic polyps. The largest one was a pedunculated polyp of about 3cm in size at the level of the greater curvature. The operator opted for endoscopic mucosal resection (EMR) of the multiple polyps. After submucosal injection, polyps were resected using a snare (ENDO CUT® Q mode). All resected polyps were retrieved with a Roth Net® for histological evaluation.

Endoscopic internal drainage of gastric fistula after sleeve gastrectomy
Gastric fistula is a major adverse event after sleeve gastrectomy.
In this live instructional video, authors present the case of a 45-year-old woman with a complex postoperative course after sleeve gastrectomy due to a gastric leakage and a twisted stomach. The patient had already been managed with the endoscopic placement of a fully covered metal stent and a percutaneous drainage with no resolution of the fistula.
The first step of the procedure consists in the removal of a 16cm fully covered stent using a grasper. After contrast injection, the leakage and the gastric twist are visualized. Under fluoroscopic control, a 30mm pneumatic dilatation of the twist is obtained. Two double pigtail plastic stents are placed between the stomach and the abscess cavity in order to achieve internal drainage and facilitate the healing process. The percutaneous drainage will be removed one day after the procedure while the plastic stents will be removed after 3 months.

ERCP in a patient with previous subtotal gastrectomy for cancer: hybrid approach with transjejunal access
Endoscopic retrograde cholangiopancreatography (ERCP) in patients with prior gastric surgery (Roux-en-Y gastric bypass, partial or subtotal gastrectomy) is a challenging procedure. Despite technological advances in endoscopy, reaching the duodenum and entering the bile duct remains difficult. Laparoscopic assisted ERCP (LAERCP) allows the duodenum to be accessed through the excluded stomach in case of previous RYGB or through the proximal jejunum in case of gastric resection. The objective of this video is to demonstrate the hybrid approach in a patient with a previous subtotal gastrectomy for gastric cancer.

Endoscopic mucosal resection (EMR) of laterally spreading tumor in rectum and resolution of late bleeding
The objectives of this video are manifold, namely to present the totally endoscopic treatment of a laterally spreading tumor in the upper rectum with a piecemeal technique, and how to act against one of its most frequent complications, post-polypectomy bleeding.
Methods: The procedure was performed in an advanced flexible endoscopy unit, with the patient lying supine, with anesthesia (Propofol), and insufflation of carbon dioxide. A videocolonoscope was used, the lesion was identified and elevated with hydroxyethyl starch (Voluven). It was dried with a hot snare in parts ("piecemeal" technique), thereby achieving complete resection. The defect was closed with metal clips. The specimen was recovered for histopathological study.
Results: During screening colonoscopy, a 56-year-old patient was found with a 30mm granular laterally spreading tumor of the rectum (LST-G or nodular mixed type), located 15cm from the anal verge. Complete endoscopic resection of the lesion with a curative intent was performed. On postoperative day 5, proctorrhagia presented without hemodynamic alteration. Emergency endoscopy was decided upon. Upon entering with the colonoscope, we identified a clot attached to the surgical site. Once the bleeding had been confirmed, a saline solution with 1/20,000 adrenaline was injected. And then, with a hot snare, electrocoagulation was performed in the same area, combining an injection method with a thermal one and achieving a satisfying hemostasis. The patient was discharged on the same day without any other complications. The pathology report showed a villous adenoma with low-grade dysplasia, including patches of high-grade dysplasia, and injury-free resection margins.
Conclusions: EMR of laterally spreading tumors is safe, although it is not devoid of complications such as bleeding, which is present in up to 9.8 of every 100,000 polypectomies in some series (Reumkens et al., AJG 2016). It is essential to suspect and know how to solve it efficiently with the tools available at that time of emergency.
