Laparoscopic gastrectomy for gastric cancer after liver transplantation
It has already been demonstrated that laparoscopic gastrectomy is a safe approach for early gastric cancer. It can provide the same oncological outcomes as open gastrectomy with the benefit of fewer complications and early recovery.
Liver transplantation has a high incidence rate in the Korean population, just like gastric cancer. Additionally, South Korea has the highest incidence of this type of cancer worldwide. Patients who had received a liver transplant might benefit from a better recovery thanks to laparoscopic gastrectomy, and this approach can be performed by experienced surgeons.
Please add in the text narrative how you performed the anastomosis.

Leiomyosarcoma paracaval laparoscopic resection
Primary retroperitoneal tumors are rare, usually malignant and of mesenchymal origin. Surgery is the treatment of choice and complete tumor excision is the main factor which determines the prognosis. They represent between 0.3 and 0.8% of all neoplasms.
The most frequent tumors are sarcomas in their different varieties (totaling 83.7%), mainly liposarcomas (6-20%) and leiomyosarcomas (8-10%); 85% of retroperitoneal tumors are malignant and, of these, about 50% are sarcomas.
The involvement of the inferior vena cava in different tumor processes has long represented a criterion of inoperability and unresectability.
Extirpative surgery of the entire lesion is the treatment of choice for retroperitoneal tumors, but it is not always possible due to the infiltrative commitment of vital structures, despite the possibility of large visceral resections (stomach, kidney, spleen, tail of the pancreas, duodenum, colon, abdominal cava, etc.) and in which case we will not talk about recurrence but about residual tumor.
The laparoscopic approach performed by a multidisciplinary team with experience and expertise can help establish a correct diagnosis and achieve a fine dissection of the lesion, even if it is in difficult anatomical regions.
The video shows a laparoscopic resection of a paracaval mass of unknown origin. This is the case of a 39-year-old female patient who presents with abdominal pain in the epigastrium and right hypochondrium with 2 weeks of evolution. She receives analgesic treatment without any improvement accompanied by vomiting of gastrobiliary content, exacerbation of pain (VAS of 9/10). Hematic biometrics and blood chemistry demonstrated normal results. Ultrasound, CT-scan of the abdomen, and magnetic resonance cholangiography showed a pericaval tumor of about 6 or 4cm, not compromising the inferior vena cava with intimate interphase. After an appropriate assessment by the multidisciplinary team, it is decided to perform a laparoscopic resection.
Operating time was 110 minutes with insignificant blood loss. The procedure is performed successfully without any complications. There were no intraoperative complications. Oral feeding was reintroduced on the first postoperative day and the patient was discharged on postoperative day 2, without complications. Histopathological examination revealed a low-grade leiomyosarcoma. 5 years of follow-up without adjacent lesions.

Proximal gastrectomy with stapled circular esophagogastrostomy: manual purse-string technique
Early tumors of the esophagogastric junction can be managed with a minimally invasive proximal gastrectomy. This operation has recently been reevaluated for early-stage tumors since it offers a good postoperative quality of life with oncological outcomes equivalent to more extended procedures. In this video, we present the case of a 72-year-old man presenting with a 2cm adenocarcinoma of the esophagogastric junction. The clinical stage of the lesion was T1N0. A laparoscopic proximal gastrectomy with stapled circular esophagogastrostomy was decided upon. Five ports were placed. The left trocar incision was enlarged to introduce the circular stapler for the anastomoses and for specimen extraction. The procedure began with a complete abdominal exploration to rule out peritoneal metastases. The gastrocolic and gastrosplenic ligaments were divided with an ultrasonic scalpel. Short splenic vessels were clipped and divided and the greater curvature completely isolated with careful preservation of the gastroepiploic arcade and of the right gastroepiploic artery and vein. Left gastric vessels were divided at their origin with a vascular stapler and the distal esophagus was isolated through the diaphragmatic hiatus. A gastric tube was created with multiple applications of a linear stapler. The anvil of the circular stapler was secured to the esophageal stump with a hand-sewn purse-string suture in order to avoid the overlap of two suture lines. The esophagogastric anastomosis was then achieved with a circular stapler.

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.

Pylorus-preserving laparoscopic gastrectomy with pyloric balloon dilatation
Gastric cancer screening programs implemented by Japan and South Korea have shown impressive results in terms of the increasing proportion of early gastric cancer diagnosis. Because of this, more interest has been focused on preserving the organ function in order to improve postoperative quality of life aiming to reduce complications or sequelae and avoiding large resections. Pylorus-preserving gastrectomy (PPG) was first introduced by Maki et al. and it is probably the most representative technique of function-preserving gastrectomy. It has been reported that, due to an impaired pyloric function, patients may occasionally experience a sensation of gastric fullness after food intake as well as long-term food retention in the remnant stomach. This delayed gastric emptying caused by pyloric spasms has been shown to decrease the patient’s quality of life. There is no standardized management strategy at present, and consequently gastric surgeons have often found themselves hesitant to perform this minimally invasive, function-preserving surgery. Here, we present a PPG case followed by a pyloric spasm, which was successfully treated with balloon dilatation.

A young lady with dysphagia and GIST after a complicated sleeve gastrectomy for morbid obesity
A 34 year-old woman was referred to us for persistent dysphagia and retrosternal chest pain, aggravated by eating. Two years earlier, she underwent a laparoscopic sleeve gastrectomy for morbid obesity.
Her operation was complicated by septic shock due to an esophagogastric fistula with subphrenic abscesses, and on postoperative day 20, she underwent a laparotomy, abscess debridement and drainage, splenectomy and application of cyanoacrylate-based glue, followed by endoscopic positioning of a self-expandable partially coated prosthesis.
Three weeks afterwards, her prosthesis was replaced with a self-expandable fully coated prosthesis due to persistent leak. This prosthesis was finally removed after 7 weeks.
One year after her operation, at gastroscopy, a 25mm submucosal nodule covered with an ulcerated mucosa was found in the proximal antrum. Biopsy was negative, and endoscopic ultrasonography was suggestive of GIST.
She underwent an esophageal manometry, which was indicative of esophagogastric junction outflow obstruction. Her barium swallow test showed a delayed esophageal emptying due to the narrowing and twisting of the proximal part of the stomach. Her abdominal MRI was normal.
An exploratory laparoscopy was indicated for adhesiolysis and removal of the antral lesion.
Total duration of the operation was 3 hours. Her postoperative course was uneventful and she was discharged on postoperative day 6.
Her postoperative swallow study showed the easy passage of the contrast agent with no leaks. The patient completely recovered from her symptoms, and remained asymptomatic after 30 months. Final histology of her lesion evidenced a foreign body granuloma.

Laparoscopic Biliopancreatic Diversion with Duodenal Switch (BPD/DS)
Morbid obesity has reached epidemic proportions. Biliopancreatic diversion with duodenal switch (BPD-DS) is the most effective bariatric surgery procedure for weight loss. This procedure was first described by Scopinaro in 1979. It consisted of a horizontal gastrectomy, a transection of the bowel halfway from the ligament of Treitz and the ileocecal junction, and a Roux-en-Y reconstruction with a 50cm common channel. This was later modified: the duodenal switch was added and the gastrectomy was performed in a vertical sleeve fashion, thereby preserving the pylorus and increasing the common channel to 100cm. This modification greatly reduced the incidence of marginal ulceration, dumping, and nutritional deficiencies. However, this operation is still uncommon due to the perceived technical difficulty and risk of nutritional morbidity. This video demonstrates a standardized technique for this complex procedure.

Laparoscopic management of perforated ulcer of the stomach
A 43-year-old woman with a history of chronic use of NSAIDs was admitted to the emergency care unit for acute abdominal epigastric pain. CT-scan showed both free air and fluid in the peritoneal cavity with marked thickening and irregularity at the level of the gastric antrum and the duodenal bulb. The patient underwent emergency laparoscopy. A large amount of purulent fluid was found in the peritoneal cavity and evacuated. The gastric defect was identified at the level of the anterior wall of the gastric antrum. A 2/0 Vicryl suture is used to oversew the perforation. As an additional protection, an omental patch was brought in place and fixed against the sutured lesion. Abundant peritoneal lavage was performed. The patient was discharged on postoperative day 5. One month later, esophagogastroduodenoscopies (EGDs) with biopsies of the ulcer’s margins were performed.

Laparoscopic total gastrectomy
A multimodality approach remains the only potential treatment for advanced gastric cancer. Oncological outcomes seem to be equivalent either in open surgery or in minimally invasive surgery. Therefore, laparoscopic gastric resection is expanding in expert centers.
The authors present a clinical case of a 70-year-old woman with no relevant clinical past. She presented with a 1-month complaint of epigastric pain and melena. She underwent an upper endoscopy, which showed an ulcerated gastric lesion at the lesser curvature. Biopsy revealed a poorly cohesive gastric carcinoma with signet ring cells. Thoraco-abdominal-pelvic CT-scan revealed a thickening of the gastric wall associated with multiple perigastric and celiac trunk lymph nodes. She was proposed for perioperative chemotherapy. On the restaging CT-scan, there was no evidence of disease progression and therefore she underwent a laparoscopic radical total gastrectomy.
The benefits of minimally invasive surgery, combined with the increasing evidence of oncological results overlapping with open surgery, have contributed to the progressive implementation of laparoscopic surgery in the treatment of malignant gastric pathology.

Wilkie's syndrome surgery
Wilkie’s syndrome (or superior mesenteric artery syndrome) was first described by Von Rokitansky in 1861. It consists in an extrinsic pressure over the third duodenal portion originating from an uncertain cause. Wilkie found a decreased angle (25 degrees, or less) between the superior mesenteric artery and the aorta, conditioning a duodenal (3rd portion) obstruction of vascular origin. It is associated with weight loss. The real incidence remains unknown due to the lack of diagnosis. However, the estimated incidence varies between 0.013 to 1% of the population. The male/female ratio is 2:3, ranging age between 10 and 39 years old.
Symptoms include postprandial abdominal pain, nausea and vomiting, weight loss, early gastric fullness and anorexia (acute high gastroduodenal obstruction).
Diagnostic studies include barium esophageal gastroduodenal series, CT-scan, MRI, high endoscopy (peptic esophagitis, ulcer). Endoscopic studies must come together with barium esophageal gastroduodenal X-ray studies.
Surgical treatment is performed when there is no response to medical treatment, consisting in duodenojejunal anastomoses, with Treitz’s ligament division. Gastrojejunal anastomosis is an alternative option. Laparoscopic surgical treatment can be performed.

Robotic Nissen fundoplication with the da Vinci Xi robotic surgical system
For a long time, laparoscopic Nissen fundoplication has been used to treat gastroesophageal reflux disease (GERD). The main challenges of laparoscopic Nissen fundoplication involve the 2-dimensional visualization, exposure of complex gastroesophageal anatomy, and suturing of the wrap fundoplication. In 1999, robotic Nissen fundoplication, a completely new technique, was introduced, demonstrating advantages over conventional laparoscopic surgery due to improved manual dexterity, ergonomics, and 3-dimensional visualization. However, time spent on robotic platform docking and arm clashing during the procedure are factors that surgeons often find cumbersome and time-consuming. The newest surgical platform, the da Vinci Xi surgical robotic system, can help to overcome such problems. This video shows a stepwise approach of the da Vinci Xi docking process and surgical technique demonstrating fundoplication according to the Nissen technique.

Fully robotic Roux-en-Y gastric bypass
Roux-en-Y gastric bypass is becoming increasingly popular. The use of the surgical robot is developing rapidly, and this is especially true for digestive surgery. The aim of this video is to show that Roux-en-Y gastric bypass can be performed using a totally robotic approach. When using the robot, one follows the same steps as for a conventional intervention. The 3D vision and the degrees of freedom of the instruments facilitate the dissection, especially around the cardia, and for suturing procedures. The surgeon takes advantage of the console's user friendly set-up which does not put his/her shoulders or back in a vulnerable position, as they sometimes are when using a laparoscopic approach.

LIVE INTERACTIVE SURGERY: robotic total gastrectomy highlighting esojejunal anastomosis
This video presents the case of a 71-year-old man with a BMI of 29. He was admitted to the emergency room for fatigue, severe anemia, and abdominal pain. His past medical history was significant for cardiac disease, aortic valve stenosis, and small adrenal adenoma. His past surgical history included a cholecystectomy and a prostatectomy. Work-up started with an endoscopy which showed an ulcer at the antrum, which was biopsied and showed signet cell adenocarcinoma. CT-scan confirmed the presence of a large bulky lesion and ruled out the presence of a metastatic disease. The patient was admitted again for bleeding and hematemesis and he was scheduled for a total gastrectomy. He had an exploratory laparoscopy which showed no signs of carcinomatosis. He also had preoperative chemotherapy.
This live interactive video demonstrates a robotic total gastrectomy for gastric cancer, including a stepwise lymphadenectomy and precise thorough description of esojejunal anastomosis.

The patient was admitted again for bleeding and hematemesis and he was scheduled for a total gastrectomy. He had an exploratory laparoscopy which showed no signs of carcinomatosis. He also had preoperative chemotherapy.
This live interactive video demonstrates a robotic total gastrectomy for gastric cancer, including a stepwise lymphadenectomy and precise thorough description of esojejunal anastomosis.
Laparoscopic revision of Nissen fundoplication to Roux-en-Y gastric bypass
Introduction: Obesity is a known etiological factor for gastroesophageal reflux disease (GERD) and is also a growing public health concern. Although Nissen fundoplication is a highly effective technique to treat GERD, it may fail in obese patients. Roux-en-Y gastric bypass provides excellent long-term control of GERD symptoms with the additional benefit of weight loss.
Clinical case: A 57-year-old woman underwent a laparoscopic Nissen fundoplication for GERD (BMI 30.0 Kg/m2) with excellent outcomes during the first postoperative year in 2011. Two years later, GERD symptoms recurred, and her weight increased progressively (BMI of 36.0 Kg/m2). The patient was proposed to a laparoscopic conversion of Nissen fundoplication to a Roux-en-Y gastric bypass. The procedure was uneventful, and the patient was discharged on postoperative day 4. One year later, she remained asymptomatic, off antacids medication, and with her weight decreased to 63.5Kg which corresponded to a BMI of 25.4 Kg/m2.
Discussion/conclusion: Roux-en-Y gastric bypass successfully reduces GERD symptoms by diverting bile away from the esophagus, decreasing acid production in the gastric pouch, therefore limiting the amount of acid reflux and by promoting weight loss decreases abdominal pressure over the lower esophageal sphincter and esophageal hiatus. In obese patients (BMI>35) with GERD, Roux-en-Y gastric bypass seems to be the most effective and advantageous treatment since it provides control of GERD symptoms with the additional benefit of weight loss. In patients who have previously undergone anti-reflux surgery, bariatric surgery can be technically demanding. However, if performed by high-volume surgeons in high-volume centers, it is perfectly feasible with low morbidity and excellent results.

Laparoscopic subtotal gastrectomy with ICG-oriented extended D2 (D2+) lymphadenectomy
The concept of fluorescence-guided navigation surgery based on indocyanine green (ICG) testifies to a developing interest in many fields of surgical oncology. The technique seems to be promising, also during nodal dissection in gastric and colorectal surgery in the so-called “ICG-guided nodal navigation”.
In this video, we present the clinical case of 36-year-old man with a seeming early stage antral gastric adenocarcinoma, as preoperatively defined, submitted to a laparoscopic subtotal gastrectomy and D2+ lymphadenectomy.
Before surgery, the patient was submitted to endoscopy with the objective to inject indocyanine green near the tumor (2mL injected into the mucosa 2cm proximally and 2cm distally to the tumor) in order to visualize the lymphatic basin of that tumor during the operation.
Thanks to the ICG’s fluorescence with the light emitted from the photodynamic eye of our laparoscopic system (Stryker 1588® camera), it is possible to clearly visualize both the individual lymph nodes and the lymphatic collectors which drain ICG (and lymph) of the specific mucosal area previously marked with indocyanine green.
This technique could allow for a more precise and radical nodal dissection and a safer work respecting vascular and nerve structures.

Giant hiatal hernia: pleural incision helping defect closure without tension
Incidence of hiatal hernias (HH) increases with age. Approximately 60% of persons aged over 50 have a HH. Most of them are asymptomatic patients and may be discovered incidentally; others may be symptomatic and their presentation differs depending on hernia type.
We present the case of a 65-year-old woman, complaining of abdominal pain and vomiting. CT-scan showed a giant hiatal sliding hernia with almost the whole stomach in an intrathoracic position. Surgery was put forward to the patient for HH correction and Nissen procedure and she accepted it.
Although a uniform definition does not exist, a giant HH is considered a hernia which includes at least 30% of the stomach in the chest. Usually, a giant HH is a type III hernia with a sliding and paraesophageal component, and consequently patients may complain of pain, heartburn, dysphagia, and vomiting. Surgery ordinarily includes four steps: hernia sac dissection and resection, esophageal mobilization, crural repair, and fundoplication. To prevent tension due to a large hiatus, relaxation of the diaphragmatic crura can be associated with the use of a mesh. However, mesh use is still a matter of debate because of severe associated complications, such as erosions requiring gastric resection. In this case, we decided to deliberately make a pleural incision, in order to reduce tension preventing the use of a mesh with all of its potential complications. This procedure, already described by some authors, is not associated with respiratory complications because of the difference in abdominal and respiratory pressures observed in laparoscopic surgery. The patient progressed favorably and was discharged asymptomatically on postoperative day 2.
