| 1 | Improved techniques for double-balloon-enteroscopy-assisted endoscopic retrograde cholangiopancreatography显示文摘AIM: To investigate the clinical outcome of double balloon enteroscopy (DBE)-assisted endoscopic retrograde cholangiopancreatography (DB-ERCP) in patients with altered gastrointestinal anatomy. METHODS: Between September 2006 and April 2011, 47 procedures of DB-ERCP were performed in 28 patients with a Roux-en-Y total gastrectomy (n = 11), Billroth Ⅱ gastrectomy (n = 15), or Roux-en-Y anastomosis with hepaticojejunostomy (n = 2). DB-ERCP was performed using a short-type DBE combined with several technical innovations such as using an endoscope attachment, marking by submucosal tattooing,selectively applying contrast medium, and CO2 insufflations. RESULTS: The papilla of Vater or hepaticojejunostomy site was reached in its entirety with a 96% success rate (45/47 procedures). There were no significant differences in the success rate of reaching the blind end with a DBE among Roux-en-Y total gastrectomy (96%), Billroth Ⅱ reconstruction (94%), or pancreatoduodenectomy (100%), respectively (P = 0.91). The total successful rate of cannulation and contrast enhancement of the target bile duct in patients whom the blind end was reached with a DBE was 40/45 procedures (89%). Again, there were no significant differences in the success rate of cannulation and contrast enhancement of the target bile duct with a DBE among Roux-en-Y total gastrectomy (88 %), Billroth Ⅱ reconstruction (89%), or pancreatoduodenectomy (100%), respectively (P = 0.67). Treatment was achieved in all 40 procedures (100%) in patients whom the contrast enhancement of the bile duct was successful. Common endoscopic treatments were endoscopic biliary drainage (24 procedures) and extraction of stones (14 procedures). Biliary drainage was done by placement of plastic stents. Stones extraction was done by lithotomy with the mechanical lithotripter followed by extraction with a basket or by the balloon pull-through method. Endoscopic sphincterotomy was performed in 14 procedures with a needle precutting knife using a guidewire. The mean total duration of the procedure was 93.6 ± 6.8 min and the mean time required to reach the papilla was 30.5 ± 3.7 min. The mean time required to reach the papilla tended to be shorter in Billroth Ⅱ reconstruction (20.9 ± 5.8 min) than that in Roux-en-Y total gastrectomy (37.1 ± 4.9 min) but there was no significant difference (P = 0.09). A major complication occurred in one patient (3.5%); perforation of the long limb in a patient with Billroth Ⅱ anastomosis.CONCLUSION: Short-type DBE combined with several technical innovations enabled us to perform ERCP in most patients with altered gastrointestinal anatomy. | Takashi Osoegawa Yasuaki Motomura Kazuya Akahoshi Naomi Higuchi Yoshimasa Tanaka Terumasa Hisano Souichi Itaba Junya Gibo Mariko Yamada Masaru Kubokawa Yorinobu Sumida Hirotada Akiho Eikichi Ihara Kazuhiko Nakamura | 2012 | World Journal of Gastroenterology2012，18，46： | 7 |
| 2 | Hematogenous umbilical metastasis from colon cancer treated by palliative single-incision laparoscopic surgery显示文摘Sister Mary Joseph’s nodule(SMJN)is a rare umbilical nodule that develops secondary to metastatic cancer.Primary malignancies are located in the abdomen or pelvis.Patients with SMJN have a poor prognosis.An 83-year-old woman presented to our hospital with a1-month history of a rapidly enlarging umbilical mass.Endoscopic findings revealed advanced transverse colon cancer.computer tomography and fluorodeoxyglucose-positron emission tomography revealed tumors of the transverse colon,umbilicus,right inguinal lymph nodes,and left lung.The feeding arteries and drainage veins for the SMJN were the inferior epigastric vessels.Imaging findings of the left lung tumor allowed for identification of the primary lung cancer,and a diagnosis of advanced transverse colon cancer with SMJN and primary lung cancer was made.The patient underwent local resection of the SMNJ and subsequent single-site laparoscopic surgery involving right hemicolectomy and paracolic lymph node dissection.Intra-abdominal dissemination to the mesocolon was confirmed during surgery.Histopathologically,the transverse colon cancer was confirmed to be moderately differentiated tubular adenocarcinoma.We suspect that SMJN may occur via a hematogenous pathway.Although chemotherapy for colon cancer and thoracoscopic surgery for the primary lung cancer were scheduled,the patient and her family desired home hospice.Seven months after surgery,she died of rapidly growing lung cancer. | Tomohide Hori Noriyuki Okada Masaya Nakauchi Shuji Hiramoto Ayako Kikuchi-Mizota Masahisa Kyogoku Fumitaka Oike Hidemitsu Sugimoto Junya Tanaka Yoshiki Morikami Kaori Shigemoto Toyotsugu Ota Masanobu Kaneko Masato Nakatsuji Shunji Okae Takahiro Tanaka Daigo Gunji Akira Yoshioka | 2013 | World Journal of Gastrointestinal Surgery2013，5，10： | 2 |

| 5 | Management of the late effects of disconnected pancreatic duct syndrome: A case report显示文摘BACKGROUND There have been few reports about the late effects of disconnected pancreatic duct syndrome(DPDS). Although few reports have described the recurrence interval of pancreatitis, it might be rare for recurrence to occur more than 5 years later.Herein, we describe a case of recurrence in an 81-year-old man after the treatment of walled-off necrosis(WON) with pancreatic transection 7 years ago.CASE SUMMARY An 81-year-old man visited our hospital with chief complaints of fever and abdominal pain 7 years after the onset of WON due to severe necrotic pancreatitis. His medical history included an abdominal aortic aneurysm(AAA),hypertension, dyslipidemia, and chronic kidney disease. Computed tomography(CT) scan showed that the pancreatic fluid collection(PFC) had spread to the aorta with inflammation surrounding it, and CT findings suggested that bleeding occurred from the vasodilation due to splenic vein occlusion. First, we attempted to perform transpapillary drainage because of venous dilation around the residual stomach and the PFC. However, pancreatic duct drainage failed because of complete main pancreatic duct disruption. Second, we performed endoscopic ultrasound-guided drainage. After transmural drainage, the inflammation improved and stenting for the AAA was performed successfully. The inflammation was resolved, and he has been free from infection for more than 2 years after the procedure.CONCLUSION This case highlights the importance of continued follow-up of patients for recurrence after the treatment of WON with pancreatic transection. | Reiko Yamada Yuhei Umeda Yasunori Shiono Hiroaki Okuse Naoki Kuroda Junya Tsuboi Hiroyuki Inoue Yasuhiko Hamada Kyosuke Tanaka Noriyuki Horiki Yoshiyuki Takei | 2019 | World Journal of Clinical Cases2019，7，9： | 1 |

| 8 | 2-D localization system utilizing M-sequence encoded laser beam scanning显示文摘In this paper, as the active position measurement system, a novel method for a two-dimensional localization system using M-sequence signal is proposed. The feature of this system is to realize a position measurement only by scanning the encoded laser beams from fixing points to a measurement field, and by observing it. First, both the system configuration and encoding method were practically considered, and an order and an initial value of M-sequence signal were selected for encoding. This method is based on discrete angle measurement therefore the resolution has its own limitation. To overcome this limitation, analogue phase shift detecting method was introduced. System design was performed and applied to position measurement experiments. The experimental results show that the measurement error of the analogue method is 1/3 of that of the discrete method. | Shinji Ohyama Kiyoshi Tanaka Junya Takayama | 2007 | 仪器仪表学报2007，28，3： | 0 |
