| 2 | Colon perforation due to antigenemia-negative cytomegalovirus gastroenteritis after liver transplantation: A case report and review of literature显示文摘BACKGROUND Cytomegalovirus(CMV) remains a critical complication after solid-organ transplantation. The CMV antigenemia(AG) test is useful for monitoring CMV infection. Although the AG-positivity rate in CMV gastroenteritis is known to be low at onset, almost all cases become positive during the disease course. We treated a patient with transverse colon perforation due to AG-negative CMV gastroenteritis, following a living donor liver transplantation(LDLT).CASE SUMMARY The patient was a 52-year-old woman with decompensated liver cirrhosis as a result of autoimmune hepatitis who underwent a blood-type compatible LDLT with her second son as the donor. On day 20 after surgery, upper and lower gastrointestinal endoscopy(GE) revealed multiple gastric ulcers and transverse colon ulcers. The biopsy tissue immunostaining confirmed a diagnosis of CMV gastroenteritis. On day 28 after surgery, an abdominal computed tomography revealed transverse colon perforation, and simple lavage and drainage were performed along with an urgent ileostomy. Although the repeated remission and aggravation of CMV gastroenteritis and acute cellular rejection made the control of immunosuppression difficult, the upper GE eventually revealed an improvement in the gastric ulcers, and the biopsy samples were negative for CMV. The CMV-AG test remained negative, therefore, we had to evaluate the status of the CMV infection on the basis of the clinical symptoms and GE.CONCLUSION This case report suggests a monitoring method that could be useful for AGnegative CMV gastroenteritis after a solid-organ transplantation. | Takahiro Yokose Hideaki Obara Masahiro Shinoda Yutaka Nakano Minoru Kitago Hiroshi Yagi Yuta Abe Yohei Yamada Kentaro Matsubara Go Oshima Shutaro Hori Sho Ibuki Hisanobu Higashi Yuki Masuda Masanori Hayashi Miho Kawaida Takehiko Mori Takumi Fujimura Ken Hoshino Kaori Kameyama Tatsuo Kuroda Yuko Kitagawa | 2019 | World Journal of Gastroenterology2019，25，15： | 5 |

| 4 | Cutting edge of endoscopic full-thickness resection for gastric tumor显示文摘Recently,several studies have reported local full-thickness resection techniques using flexible endoscopy for gastric tumors,such as gastrointestinal stromal tumors,gastric carcinoid tumors,and early gastric cancer(EGC). These techniques have the advantage of allowing precise resection lines to be determined using intraluminal endoscopy. Thus,it is possible to minimize the resection area and subsequent deformity. Some of these methods include:(1) classical laparoscopic and endoscopic cooperative surgery(LECS);(2) inverted LECS;(3) combination of laparoscopic and endoscopic approaches to neoplasia with non-exposure technique; and(4) non-exposed endoscopic wall-inversion surgery. Furthermore,a recent prospective multicenter trial of the sentinel node navigation surgery(SNNS) for EGC has shown acceptable results in terms of sentinel node detection rate and the accuracy of nodal metastasis. Endoscopic full-thickness resection with SNNS is expected to become a treatment option that bridges the gap between endoscopic submucosal dissection and standard surgery for EGC. In the future,the indications for these procedures for gastric tumors could be expanded. | Tadateru Maehata Osamu Goto Hiroya Takeuchi Yuko Kitagawa Naohisa Yahagi | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，16： | 4 |
| 5 | Computed tomography attenuation values of ascites are helpful to predict perforation site显示文摘AIM:To evaluate the effect of computed tomography(CT) attenuation values of ascites on gastrointestinal(GI) perforation site prediction.METHODS:The CT attenuation values of the ascites from 51 patients with GI perforations were measured by volume rendering to calculate the mean values.The effect of the CT attenuation values of the ascites on perforation site prediction and postoperative complications was evaluated.RESULTS:Of 24 patients with colorectal perforations,the CT attenuation values of ascites were significantly higher than those in patients with perforations at other sites [22.5 Hounsfield units(HU) vs 16.5 HU,respectively,P = 0.006].Colorectal perforation was significantly associated with postoperative complications(P = 0.038).The prediction rate of colorectal perforation using attenuation values as an auxiliary diagnosis improved by 9.8% compared to that of CT findings alone(92.2% vs 82.4%).CONCLUSION:The CT attenuation values of ascites could facilitate the prediction of perforation sites and postoperative complications in GI perforations,particularly in cases in which the perforation sites are difficult to predict by CT findings alone. | Ryo Seishima Koji Okabayashi Hirotoshi Hasegawa Masashi Tsuruta Hiroki Hoshino Toru Yamada Yuko Kitagawa | 2015 | World Journal of Gastroenterology2015，21，5： | 3 |
| 6 | Pre-hepatectomy type Ⅳ collagen 7S predicts post-hepatectomy liver failure and recovery显示文摘BACKGROUND Liver resection is an effective treatment for benign and malignant liver tumors.However,a method for preoperative evaluation of hepatic reserve has not yet been established.Previously reported assessments of preoperative hepatic reserve focused only on liver failure in the early postoperative period and did not consider the long-term recovery of hepatic reserve.When determining eligibility for hepatectomy,the underlying pathophysiology needs to be considered to determine if the functional hepatic reserve can withstand both surgery and any postoperative therapy.AIM To identify pre-hepatectomy factors associated with both early postoperative liver failure and long-term postoperative liver function recovery.METHODS This study was a retrospective cohort study.We retrospectively investigated 215 patients who underwent hepatectomy at our hospital between May 2013 and December 2016.Early post-hepatectomy liver failure(PHLF)was defined using the International Study Group of Liver Surgery’s definition of PHLF.Long-term postoperative recovery of liver function was defined as the time taken for serum total bilirubin and albumin levels to return to levels of<2 mg/dL and>2.8 g/dL,respectively,and the time taken for Child-Pugh score to return to Child-Pugh class A.RESULTS Preoperative type IV collagen 7S was identified as a significant independent factor associated with both PHLF and postoperative long-term recovery of liver function.Further analysis revealed that the time taken for the recovery of Child-Pugh scores and serum total bilirubin and albumin levels was significantly shorter in patients with type IV collagen 7S≤6 ng/mL than in those with type IV collagen 7S>6 ng/mL.In additional analyses,similar results were observed in patients without chronic viral hepatitis associated with fibrosis.CONCLUSION Preoperative type IV collagen 7S is a preoperative predictor of PHLF and longterm postoperative liver function recovery.It can also be used in patients without chronic hepatitis virus. | Masatsugu Ishii Osamu Itano Masahiro Shinoda Minoru Kitago Yuta Abe Taizo Hibi Hiroshi Yagi Ayano Takeuchi Hanako Tsujikawa Tokiya Abe Yuko Kitagawa | 2020 | World Journal of Gastroenterology2020，26，7： | 3 |
| 7 | Current status and challenges in sentinel node navigation surgery for early gastric cancer显示文摘As an optimal surgical procedure to accurately evaluate lymph node(LN)metastasis during surgery with minimal surgical resection,we have been developing sentinel node(SN)biopsy for early gastric cancer since the 1990s.Twelve institutions from the Japanese Society of Sentinel Node Navigation Surgery(SNNS),including Keio University Hospital,conducted a multicenter prospective trial to validate the SN concept using the dual-tracer method with blue dye and a radioisotope.According to the results,397 patients were included in the final analysis,and the overall accuracy in detecting LN metastasis using SN biopsy was 99%(383 of 387).Based on the validation study,we are targeting cT1N0 with a primary tumor of≤4 cm in diameter as an indication for SN biopsy for gastric cancer.We are currently running a multicenter nonrandomized phaseⅢtrial to assess the safety and efficacy of SN navigation surgery.The Korean group has reported the result of a multicenter randomized phaseⅢtrial.Since meticulous gastric cancer in the remnant stomach was rescued by subsequent gastrectomy,the disease-specific survival was comparable between the two techniques,implying that SN navigation surgery can be an alternative to standard gastrectomy.With the development of SN biopsy procedure and treatment modalities,the application of SN biopsy will be expanded to achieve an individualized minimally invasive surgery. | Satoru Matsuda Tomoyuki Irino Hirofumi Kawakubo Hiroya Takeuchi Yuko Kitagawa | 2021 | Chinese Journal of Cancer Research2021，33，2： | 3 |
| 8 | Endoscopic removal of foreign bodies:A retrospective study in Japan显示文摘BACKGROUND The ingestion of foreign bodies(FBs)and food bolus impaction(FBI)in the digestive tract are commonly encountered clinical problems.Methods to handle such problems continue to evolve offering advantages,such as the avoidance of surgery,reduced cost,improved visualization,reduced morbidity,and high removal success rate.However,to date,no studies have evaluated the endoscopic management of FBs in Japan.AIM To elucidate level of safety and efficacy in the endoscopic management of FBs and FBI.METHODS A total of 215 procedures were performed at Keio University Hospital between November 2007 and August 2018.Data were collected from medical charts,and endoscopic details were collected from an endoscopic reporting system.Procedures performed with a flexible gastrointestinal endoscope were only taken into account.Patients who underwent a technique involving FB or FBI from the digestive tract were only included.Data on patient sex,patient age,outpatient,inpatient,FB type,FB location,procedure time,procedure type,removal device type,success,and technical complications were reviewed and analyzed retrospectively.RESULTS Among the 215 procedures,136(63.3%)were performed in old adults(≥60 years),180(83.7%)procedures were performed in outpatients.The most common type of FBs were press-through-pack(PTP)medications[72(33.5%)cases],FBI[47(21.9%)],Anisakis parasite(AP)[41(19.1%)cases].Most FBs were located in the esophagus[130(60.5%)cases]followed by the stomach[68(31.6%)cases].AP was commonly found in the stomach[39(57.4%)cases],and it was removed using biopsy forceps in 97.5%of the cases.The most common FBs according to anatomical location were PTP medications(40%)and dental prostheses(DP)(40%)in the laryngopharynx,PTP(48.5%)in the esophagus,AP(57.4%)in the stomach,DP(37.5%)in the small intestine and video capsule endoscopy device(75%)in the colon.A transparent cap with grasping forceps was the most commonly used device[82(38.1%)cases].The success rate of the procedure was 100%,and complication were observed in only one case(0.5%).CONCLUSION Endoscopic management of FBs and FBI in our Hospital is extremely safe and effective. | Kenji JL Limpias Kamiya Naoki Hosoe Kaoru Takabayashi Yukie Hayashi Xi Sun Ryoichi Miyanaga Kayoko Fukuhara Seiichiro Fukuhara Makoto Naganuma Atsushi Nakayama Motohiko Kato Tadateru Maehata Rieko Nakamura Koichi Ueno Junichi Sasaki Yuko Kitagawa Naohisa Yahagi Haruhiko Ogata Takanori Kanai | 2020 | World Journal of Gastrointestinal Endoscopy2020，12，1： | 3 |

| 19 | Association of anastomotic leakage with long-term oncologic outcomes of patients with esophagogastric junction cancer显示文摘BACKGROUND Despite improvements in surgical procedures and peri-operative patients management,the postoperative complications in esophagogastric junction(EGJ)cancer remain high because of technical aspects.Several studies have indicated the negative influence of postoperative infectious complications on long-term survival after gastrointestinal surgery.However,no study has shown the association between postoperative complications and long-term survival of patients with EGJ cancer.AIM To elucidate influence of postoperative complications on the long-term outcomes of patients with EGJ cancer.METHODS A total of 122 patients who underwent surgery for EGJ cancer at the Keio University were included in this study.We examined the association between complications and long-term oncologic outcomes.RESULTS In all patients,the 3-year overall survival(OS)rate was 71.9%,and the recurrencefree survival(RFS)rate was 67.5%.Compared with patients without anastomotic leakage,those with anastomotic leakage had poor median OS(8 mo vs not reached,P=0.028)and median RFS(5 mo vs not reached,P=0.055).Among patients with cervical anastomosis,there were not significant differences between patients with and without anastomotic leakage.However,among patients who underwent intrathoracic anastomosis,patients with anastomotic leakage had significantly worse OS(P=0.002)and RFS(P=0.005).CONCLUSION Anastomotic leakage was significantly associated with long-term oncologic outcomes of patients with EGJ cancer,especially those who underwent intrathoracic anastomosis.Cervical anastomosis with subtotal esophagectomy may be an option for the patients who are at high risk for anastomotic leakage. | Masashi Takeuchi Hirofumi Kawakubo Satoru Matsuda Shuhei Mayanagi Tomoyuki Irino Jun Okui Kazumasa Fukuda Rieko Nakamura Norihito Wada Hiroya Takeuchi Yuko Kitagawa | 2022 | World Journal of Gastrointestinal Surgery2022，14，1： | 1 |
