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.

Laparoscopic distal gastrectomy with Roux-en-Y reconstruction for a prepyloric lesion: a live educational procedure
This is the case of a 70-year-old patient who underwent an esophagogastroduodenoscopy for gastric pain. The exam showed a 0.5cm prepyloric ulcerated lesion with Helicobacter pylori infection. After Helicobacter pylori eradication and a CT-scan negative for secondary lesions, the patient was scheduled for a distal gastrectomy with perioperative gastroscopy.
In this original live educational video, Dr. Woo Jin Hyung describes his technique of laparoscopic distal gastrectomy with Roux-en-Y reconstruction and discusses several topics such as the comparison between laparoscopic and robotic gastrectomy, the indication for omentectomy, the choice of the surgical strategy considering the tumor location, the benefit of fluorescence in lymphatic mapping, the type of lymphadenectomy, the comparison of different energy devices and the choice of the reconstruction technique.

Robotic Heller myotomy with Dor fundoplication for esophageal achalasia
Achalasia is an esophageal motility disorder characterized by an incomplete or absent esophagogastric junction (EGJ) relaxation associated with loss of peristalsis or uncoordinated contractions of the esophageal body in response to swallowing. All available treatments for achalasia are palliative, directed towards the elimination of the outflow resistance caused by abnormal lower esophageal sphincter (LES) function and aiming to improve the symptoms related to esophageal stasis, such as dysphagia and regurgitation. Laparoscopic Heller myotomy with partial fundoplication is the current standard of care for the treatment of achalasia. It is associated with symptom improvement or relief in about 90% of patients. However, it is a challenging procedure with the potential risk of esophageal perforation reported in up to 10% of cases. Interestingly, laparoscopic myotomy has some limitations which depend on the laparoscopic technique (bidimensional vision, poor range of movement) and on the surgeon’s experience. Recently, the use of the robotic technology has been proposed claiming that it might reduce intraoperative esophageal perforation rates and improve postoperative quality of life after Heller myotomy, mainly due to the 3D view and enhanced dexterity of the surgeon. Despite significant improvements in surgical treatment, the length of myotomy is still a matter of debate to date. Substantially, although some authors proposed a limited myotomy on the lower esophagus preserving a small portion of the LES to prevent postoperative reflux, most authors recommended a myotomy extending 4 to 6cm on the esophagus and 1 to 2cm on the gastric side. In this video, we performed a 6cm long esophagogastric myotomy, with a 2.5cm proximal extension above the Z-line (endoscopically recognized) and a 3.5cm distal extension below the same landmark. In a previous experimental study with intraoperative computerized manometry, we observed that myotomy of the esophageal portion of the LES (without dissection of the gastric fibers) did not lead to any significant variation in sphincteric pressure. Instead, the dissection of the gastric fibers for at least 2 to 2.5cm on the anterior gastric wall created a significant modification of the LES pressure profile. This may be due to the interruption of the anterior portion of gastric semicircular clasp and sling fibers, with consequent loss of their hook properties on the LES pressure profile.

Thoracoscopic repair of pure esophageal atresia
A full-term baby weighing 2.8 kg was diagnosed with pure esophageal atresia. No other associated anomalies were found by abdominal sonography and echocardiography. The primary anastomosis was completed thoracoscopically after mobilization of both esophageal pouches. The patient was placed in a prone position at the edge of the operating table. A 5mm, 30-degree angled scope was introduced one fingerbreadth below the lower angle of the scapula. Two 3mm working ports were also inserted; the first in the same costal space as the camera port 3cm from the middle line and the second as high as possible in the axilla. A thin fibrous strand was found connecting both ends of the esophagus. The azygos vein was left intact. Blunt dissection was used throughout the whole procedure to preserve the aortic branches to the lower pouch, dissecting in between them. Without traction, the distance between both pouches was approximately 4cm or 4 vertebral bodies. No tracheoesophageal fistula (TEF) was identified. Nine polyglactin 5/0 sliding tumble square knots were used to complete the anastomosis. The operative time was 85 minutes. The postoperative period was uneventful. Nasogatric tube feeding started on postoperative day 2, and the patient was discharged on postoperative day 6 after performing a contrast swallow test ensuring that there is no leakage.

LIVE INTERACTIVE SURGERY: paraesophageal hernia repair: critical value of extrasaccular approach
Paraesophageal hernia (PEH) repair is a challenging procedure. Repositioning of the herniated stomach and the reduction of the sac from the mediastinum is mandatory in order to decrease the risk of recurrence. The dissection and reduction of the sac must be performed following stepwise and precise dissection rules: it must be carried out outside of the sac, in an anatomical cleavage plane. Recurrence is also related to the type of crural repair performed, some authors advocating the systematic use of prosthetic or biological reinforcement. In this video, we present a PEH repair and cruroplasty protected with an absorbable mesh and contemporary Nissen fundoplication.

LIVE INTERACTIVE SURGERY: thoracoscopic esophageal diverticulectomy and myotomy
A 65-year-old woman was referred to our hospital with complaints of dysphagia. She had a surgical history of cesarean section and cholecystectomy. Esophageal motility examination showed a normal lower esophageal sphincter (LES), and the absence of hiatal hernia and spasm in the distal part of the esophagus. The barium X-ray showed a bulky diverticulum in the middle thoracic esophagus and barium collecting inside the diverticulum without obstruction. The 3D-CT image also showed a giant diverticulum in the middle esophagus. The diverticulum was located below the azygos vein and carina of the bronchus and was sticking out from the middle esophagus in the contralateral side of the thoracic aorta. The diverticulum does not invade other organs. The patient was then proposed for an elective surgery, a thoracoscopic esophageal diverticulectomy and myotomy in a prone position.

Concurrent laparoscopic RYGB with a paraesophageal hernia (PEH) repair
This is the case of a 75-year old female patient with a medical history of bilateral mastectomy due to cancer, which occurred 30 and 15 years before referral. She was treated using adjuvant chemotherapy (tamoxifen) and radiotherapy, and had a liver-related kidney donation. The patient was found asymptomatic when she underwent a control abdominal ultrasound, which showed a 6cm hepatic mass in liver segments V and VI. A hepatic MRI was performed and showed a single liver lesion (68mm in diameter) located in the right liver lobe, and a PET-CT-scan demonstrated an increased hypermetabolic activity of the lesion without other systemic tumor dissemination. A laparoscopic right hepatectomy was scheduled. A laparoscopic surgery was performed. Laparoscopic exploration revealed multiple bilateral lesions, and an intraoperative ultrasound demonstrated a lesion in liver segment IV. An ALPPS approach was considered.
There were no complications and the patient was discharged on the third postoperative day.

Robotic partial splenectomy for cystic lesion of the spleen
We report the case of a 21-year-old woman with a cystic lesion of the spleen treated with a robotic partial splenectomy. The patient is placed in a right lateral decubitus position. Four ports are introduced into the left hypochondrium. The robot is placed at the level of the patient’s left shoulder. The intervention is begun with a lowering of the splenic flexure. Dissection is initiated at the upper pole of the spleen by retracting the stomach and by progressively dividing the different short vessels. It is decided to start the parenchymotomy approximately 1cm from the devascularized area. Transection is begun using an ultrasonic dissector. Hemostasis is subsequently achieved progressively. Transection is completed by means of a firing of the Endo GIA™ linear stapler. Hemostasis is further completed using the Aquamantys® system and bipolar sealers. The specimen is fully mobilized and placed in a bag. It is extracted by means of a small suprapubic Pfannenstiel’s incision. Pathological findings demonstrate the presence of an epidermoid cyst. The postoperative outcome is uneventful. The patient is discharged on postoperative day 4.
