Laparoscopic diagnosis of retrograde peristalsis and intussusception in Roux‐en‐Y limb after laparoscopic gastrectomy: A case report

The cause of jejunojejunal intussusception, a rare complication after Roux‐en‐Y gastric surgery, remains unclear. Here, we present a case of retrograde jejunojejunal intussusception that occurred after laparoscopic distal gastrectomy with Roux‐en‐Y reconstruction. A 51‐year‐old woman who had undergone laparoscopic distal gastrectomy and Roux‐en‐Y reconstruction for early gastric cancer 6 years previously was admitted to our hospital with abdominal pain. Abdominal CT revealed the “target sign,” and she was diagnosed as having small bowel intussusception. Laparoscopic surgery resulted in a diagnosis of retrograde intussusception of the distal jejunum of the Roux‐en‐Y anastomosis with retrograde peristalsis in the same area. The Roux‐en‐Y anastomosis site and intussuscepted segment were resected laparoscopically. To the best of our knowledge, this is the first report of laparoscopic diagnosis of retrograde peristalsis in the distal jejunum of a Roux‐en‐Y anastomosis. Additionally, relevant published reports concerning this unusual condition are discussed.     

Early gastric cancer successfully treated by endoscopic submucosal resection 1 year after laparoscopic sleeve gastrectomy with duodenal‐jejunal bypass

This case involved a 64‐year‐old female patient with a BMI of 35.3 kg/m² and poorly controlled type 2 diabetes mellitus. Preoperative upper gastrointestinal endoscopy revealed chronic, atrophic gastritis. Helicobacter pylori antibody was negative. The patient underwent laparoscopic sleeve gastrectomy with duodenal‐jejunal bypass as a metabolic surgery to treat obesity and type 2 diabetes mellitus. At 1 year postoperatively, routine endoscopy detected a flat elevated lesion at the distal gastric sleeve, near the posterior wall of the antrum; biopsy revealed adenocarcinoma. Endoscopic submucosal resection was performed without complication. This case shows the advantage of laparoscopic sleeve gastrectomy with duodenal‐jejunal bypass in screening the excluded stomach as compared to laparoscopic Roux‐en‐Y gastric bypass. Therefore, laparoscopic sleeve gastrectomy with duodenal‐jejunal bypass can be a viable alternative to laparoscopic Roux‐en‐Y gastric bypass for regions where gastric cancer is endemic.     

V‐loc™ capable of grasping surrounding tissue causes obstruction at the jejunojejunostomy after Roux‐en‐Y laparoscopic gastric bypass

Because of the increasing number of morbidly obese patients, laparoscopic Roux‐en‐Y gastric bypass surgery is increasingly being performed to treat these patients and achieve sustained weight loss. Postoperative abdominal symptoms suggestive of impaired gastrointestinal passage are a diagnostic challenge after Roux‐en‐Y gastric bypass. Here, we present the case of a V‐loc?‐induced obstruction at the jejunojejunostomy caused by the ability of the V‐loc suture to grasp surrounding tissue that required re‐laparoscopy. To our knowledge, this specific type of postoperative complication after Roux‐en‐Y gastric bypass has not been described previously.     

Gastric cancer after mini‐gastric bypass surgery: A case report and literature review

Gastric cancer in the stomach after Roux‐en‐Y gastric bypass or mini‐gastric bypass is rare, but a few cases have been reported since 1991, when the first case emerged. According to the literature, the interval between bypass surgery and the diagnosis of cancer ranged from 1 to 22 years. Given the difficulty of monitoring a bypassed stomach, the potential for gastric cancer must be considered, especially in countries with high incidence of this cancer. The literature reported the first case in the Asia–Pacific region – a woman developed advanced gastric cancer in her stomach 9 years after laparoscopic mini‐gastric bypass for morbid obesity.     

Laparoscopic total gastrectomy for advanced gastric cancer in a patient with situs inversus totalis

Situs inversus totalis (SIT) is a rare congenital anomaly. Generally, laparoscopic surgery is difficult to perform in patients with SIT because of both the potential challenges associated with unexpected vascular anomalies and the lack of standardized strategy for handling such cases. This is the first report of laparoscopic total gastrectomy with lymph node dissection for advanced gastric cancer in a patient with SIT. A 79‐year‐old man with SIT was diagnosed with advanced gastric cancer. We performed laparoscopic total gastrectomy with modified D2 lymph node dissection (D2 without splenectomy) and esophagojejunal anastomosis using an overlap method involving retrocolic Roux‐en‐Y reconstruction. The total operating time was 232 min, and blood loss was 110 mL. There were no postoperative complications. In summary, laparoscopic total gastrectomy for gastric cancer can be performed safely, even in a patient with SIT.     

History and current status of bariatric and metabolic surgeries in East Asia

Morbid obesity and obesity‐related comorbidities are major public health problems around the world, including in East Asia. Although Asian populations have been shown to have an elevated risk of type 2 diabetes mellitus, hypertension, and hyperlipidemia at a relatively lower BMI than Western populations, the Asian perspective on bariatric and metabolic surgeries has not been actively discussed until recently. Bariatric surgery in East Asia has undergone a paradigm shift since the first laparoscopic vertical bariatric surgery was performed in Taiwan in 1998, which was subsequently followed by the introduction of laparoscopic adjustable gastric banding, Roux‐en‐Y gastric bypass, and mini‐gastric bypass. Since 2006, use of laparoscopic sleeve gastrectomy has remarkably increased because of its ease, speed, and safety. With regard to metabolic surgery, a randomized controlled trial in Taiwan demonstrated that laparoscopic Roux‐en‐Y gastric bypass is more effective than laparoscopic sleeve gastrectomy for surgical treatment of poorly controlled type 2 diabetes mellitus and metabolic syndrome. In this article, we describe the history of bariatric procedures, revision surgeries, weight‐loss effect, and metabolic surgeries in Asian populations, and we also discuss minimally invasive bariatric surgery with some important citations.     

Superior mesenteric artery syndrome treated with single‐incision laparoscopy‐assisted duodenojejunostomy

Superior mesenteric artery (SMA) syndrome is an uncommon disease resulting from compression and partial obstruction of the third portion of the duodenum from the SMA. A 77‐year‐old man, who did not have a history of surgery, experienced repeated vomiting and developed abdominal distension. Abdominal CT showed a narrowed third portion of the duodenum, with a distended stomach and proximal duodenum. The patient was diagnosed as having SMA syndrome and was initially treated conservatively, but his condition did not improve. Single‐incision laparoscopy‐assisted duodenojejunostomy was performed. The patient recovered well and was discharged from hospital on postoperative day 8. Laparoscopic treatment is feasible for the treatment of SMA syndrome given its safety and minimal invasiveness. This is a report of the first case of single‐incision laparoscopy‐assisted duodenojejunostomy. This procedure is safer and less invasive than a conventional laparoscopic approach in a patient with SMA syndrome.     

Totally laparoscopic gastrectomy for early gastric cancer accompanied by huge hiatal hernia: A case report

We herein present a case in which we used a totally laparoscopic approach for early gastric cancer accompanied by a huge hiatal hernia. An 80‐year‐old Japanese woman was referred with a chief complaint of dysphagia. A clinical diagnosis of early gastric cancer, T1b (SM) N0M0, stage IA, accompanied by hiatal hernia, was made. Distal gastrectomy with D1 plus lymphadenectomy was carried out. After the gastrectomy, the hernial sac was excised and the hernial orifice was closed. Reconstruction using the Roux‐en‐Y method was selected. The postoperative course was uneventful and she was discharged on postoperative day 10.     

Jejunal intussusception at the jejunojejunostomy after laparoscopic total gastrectomy: A case report

Jejunal intussusception at the jejunojeunostomy after total gastrectomy with Roux‐en‐Y (RY) reconstruction is rare. We describe a case of jejunal intussusception at the jejunojeunostomy that developed in a 60‐year‐old woman who had undergone laparoscopic total gastrectomy with RY reconstruction for gastric cancer 4 years ago. The main presenting complaint was recurrent epigastric pain. Abdominal computed tomography showed a typical target sign suspected of antegrade intussusception into a blind loop at the jejunojeunostomy. We performed a laparoscopic operation, which revealed no intussusception or adhesions. We noted that the blind loop of the bilio‐pancreatic limb was longer and expanded. We divided the blind loop at the distal side of the jejunojeunostomy and performed suture plication between the bilio‐pancreatic limb and alimentary limb. Therefore, the appropriate length of the blind loop and the size of the jejunojeunostomy site should be carefully determined during RY reconstruction.     

Gastrointestinal stromal tumor (GIST) mistaken for pancreatic pseudocyst – case report and literature review

A 74‐year‐old female patient underwent a Roux‐en‐Y cystjejunostomy for pancreatic pseudocyst developed several melena episodes and she was surgically reappraised. The main diagnostic concern was a pancreatic cystic neoplasm. A 12 × 8.0 × 5.0 cm retro‐gastric lesion was resected and pathology report indicated an unsuspected gastrointestinal stromal tumor (GIST). The report aimed to describe an atypical presentation of GIST.     

Usefulness of indocyanine green fluorescence imaging: A case of laparoscopic distal gastrectomy after distal pancreatectomy with splenectomy

Safe preservation of the remnant stomach during distal gastrectomy in patients who have undergone distal pancreatectomy is important. During distal pancreatectomy, the splenic artery that supplies arterial blood to the cardiac part of stomach is resected. Previous reports suggested that blood flow to the remnant stomach may be insufficient when supplied by only the left inferior phrenic artery. In the present case, a 79‐year‐old woman who underwent distal pancreatectomy with splenectomy 20 years before she was diagnosed with gastric cancer and referred to our hospital. We performed laparoscopic distal gastrectomy and Roux‐en‐Y reconstruction because preoperative CT scan indicated a developed left inferior phrenic artery. To evaluate the blood supply, we employed indocyanine green fluorescence and were able to safely preserve the remnant stomach. Our experience suggests that indocyanine green fluorescence is potentially useful for evaluating blood flow to the remnant stomach.     

Laparoscopic gastrectomy after coronary artery bypass grafting using the right gastroepiploic artery: A report of two cases

We successfully executed laparoscopic distal gastrectomy in two patients who had previously undergone coronary artery bypass grafting using the right gastroepiploic artery (RGEA). A laparoscopic distal gastrectomy preserving the RGEA graft with Roux‐en‐Y reconstruction was performed on two men, one 69 years of age and one 73 years of age. In both cases, the RGEA was used during coronary artery bypass grafting for the posterior descending branch. The laparoscopic approach helped avoid injury to the RGEA associated with laparotomy and retractor placement. In addition, the locations of ports necessary for laparoscopy were situated away from the RGEA graft and from adhesions resulting from bypass. Using typical laparoscopic settings, we were able to easily identify the grafted RGEA. Thus, laparoscopic distal gastrectomy is not only less invasive than open gastrectomy procedures, but it is also associated with a lower risk of injury to the RGEA graft.     

Wilkie's syndrome in monozygotic twins treated by 3‐D laparoscopic duodenojejunostomy

Superior mesenteric artery syndrome, also known as Wilkie's syndrome, is a rare cause of proximal duodenum obstruction in children. Here, we describe the first pediatric case of superior mesenteric artery syndrome in monozygotic twin brothers. Both patients underwent 3‐D laparoscopic duodenojejunostomy at the same age with an uneventful recovery.     

全胃切除术后两种常用消化道重建方式的比较

目的探讨全胃切除术合理的消化道重建方式。方法回顾分析我院1999—2008年所开展全胃切除手术病例,选择其中最常采用的P袢空肠Roux—en—Y重建术和功能性空肠间置吻合术,对其手术难度、术后病人的并发症及营养差异进行比较。结果两种手术方法手术难度、术后并发症相差不太。P袢空肠Roux—en—Y重建术后早期适应性较好;功能性空肠间置吻合术后病人后期营养优于前者。结论全胃切除后,P袢Roux—en—Y吻合术和功能性空肠间置吻合术在改善患者术后症状和生活质量等方面是比较理想的重建术式,但功能性空肠间置吻合术是一种更符合生理,更能解决全胃切除后病人发生营养障碍的术式。     

Results of a national survey on laparoscopic bariatric surgery in Japan, 2000-2009

Introduction: In Japan, laparoscopic bariatric surgery has not been popular until recently because morbidly obese patients were infrequently encountered previous and Japanese health insurance does not cover this type of surgery. In 2010, the Japan Research Society for Endoscopic and Laparoscopic Treatments of Obesity undertook the first nationwide survey on laparoscopic bariatric surgery to evaluate its current status and outcomes. Methods: A mail survey was sent to the society's 64 member institutions, which included almost all institutions in Japan actively performing laparoscopic gastrointestinal surgery. Results: From 2000 to 2009, 340 laparoscopic bariatric procedures, in total, were performed in nine of the 64 institutions (14%). The most popular procedure was laparoscopic Roux‐en‐Y gastric bypass (LRYGB, n=147), second was laparoscopic sleeve gastrectomy (LSG, n=102), and third was laparoscopic adjustable gastric banding (LAGB, n=55). However, the number of LRYGB procedures has decreased while the number of LSG procedures has rapidly increased. Total morbidity rates were 12.2% for LRYGB, 10.9% for LAGB, and 7.8% for LSG. Percent excess weight loss was 78% at 5 years after LRYGB, 52% at 4 years after LAGB, and 68% at 2 years after LSG. Although the bariatric procedures frequently resolved or improved obesity‐related comorbidities, LRYGB appears to be superior to LAGB, as was previously reported. Conclusion: The first nationwide survey of laparoscopic bariatric surgery in Japan clearly showed the current status and outcomes of this group of procedures. The Japanese results appear to be comparable to similarly undertaken surveys in Europe and the USA.

Transumbilical single‐incision laparoscopic ileocecal resection for Crohn's disease in a child

We report the pediatric case of ileal Crohn's disease in which the patient underwent transumbilical single‐incision laparoscopic ileocecal resection. A 14‐year‐old boy with severe growth disturbance presented with intestinal obstruction. Transanal double‐balloon enteroscopy and contrast study during endoscopy revealed a cobble stone appearance and a severe stricture 15 cm in length located slightly proximal to the ileocecal valve. There was no evidence of fistula or abscess formation. Ileocecal resection was performed via an umbilical incision with conventional laparoscopic instruments, and the postoperative course was uneventful. Single‐incision laparoscopic ileocecal resection is a good procedure for uncomplicated Crohn's disease patients in childhood.     

Combined laparoscopic abdominoperineal resection and robotic‐assisted prostatectomy for synchronous double cancer of the rectum and the prostate

Here we report a combined laparoscopic abdominoperineal resection and robotic‐assisted prostatectomy. A 74‐year‐old man was diagnosed with T4b low rectal and prostate cancer. The operation was performed after neoadjuvant chemotherapy for the rectal cancer. The procedure used eight ports in total, five for laparoscopic abdominoperineal resection and six for robotic‐assisted prostatectomy. First, laparoscopic total mesorectal excision including division of the inferior mesenteric artery was performed, and then, robotic dissection of the prostate was performed. The en bloc specimen was removed through the perineal wound. Then, robotic urethrovesical anastomosis was performed. An extraperitoneal end colostomy was created to finish the operation. The operating time was 545 min, and blood loss was 170 mL. The postoperative course was uneventful, and the patient discharged on postoperative day 17. The combined laparoscopic abdominoperineal resection and robotic‐assisted prostatectomy were performed safely without any additional technical difficulty, as both procedures shared port settings and patient positions.     

Laparoscopic total pelvic exenteration with en bloc lateral lymph node dissection after neoadjuvant chemoradiotherapy for advanced primary rectal cancer

Total pelvic exenteration (TPE) may be the only procedure that can cure T4 rectal cancer that directly invades the urinary bladder or prostate. Here, we describe our experience of laparoscopic TPE with en bloc lateral lymph node dissection for advanced primary rectal cancer. A 62‐year‐old man diagnosed with advanced lower rectal cancer (T4bN0M0) underwent laparoscopic TPE with en bloc lateral lymph node dissection after neoadjuvant chemoradiotherapy. Ligation of the dorsal vein complex was performed under direct visualization through the perineal approach, and the large perineal defect was reconstructed using bilateral V‐Y advancement of the gluteus maximus musculocutaneous flaps. The ileal conduit was constructed extracorporeally through an extended umbilical port that was extended to 4 cm. The total operative time was 831 min and estimated blood loss was 600 mL. Laparoscopic TPE appears to be safe and feasible in selected patients.     

Endoscopy‐assisted laparoscopic submucosal dissection for a duodenal epithelial tumor

We present the case of a 46‐year‐old obese woman with a 3.5‐cm adenoma in the descending part of the duodenum who was treated with a totally laparoscopic approach. The preoperative examination revealed a pedunculated superficial tumor on the side of pancreas from the inferior duodenal angulus to 5 cm proximal to the papilla that was associated with massive blood flow. We chose not to perform endoscopic submucosal dissection, pancreaticoduodenectomy, or transduodenal tumor excision with laparotomy for this obese patient because of the poor exposure, risk of bleeding, and substantial invasiveness. We performed endoscopy‐assisted laparoscopic submucosal dissection as a novel laparoscopic‐endoscopic cooperative surgical approach in this patient. This surgery was surgically and oncologically safe.
