| 1 | Pseudomembranous colitis presenting as acute colonic obstruction without diarrhea in a patient with gastric Burkitt lymphoma显示文摘Pseudomembranous colitis (PMC) usually manifests asfever and diarrhea in hospitalized patients treated withsystemic antibiotics. We described a case of PMC withintestinal obstruction but without diarrhea. A 60-yearold man was hospitalized for chemotherapy for the treatment of Burkitt lymphoma of the stomach. The patient became febrile and complained of crampy abdominal pain during the post-chemotherapy nadir. Plain abdominal radiography showed some intestinal gas and niveau. Because stool cytotoxin assay for clostridium difficile was positive and colon fiberscopic examination showed a pseudomembrane at the left side of the colon,and a diagnosis of PMC was made. Treatment with intracolonic vancomycin administration by colonoscopy and nasoileus tube was successful. Physicians should take into account the possibility of bowel obstruction due to PMC occurring in patients undergoing chemotherapy and perform emergency colonoscopy examination of suspected cases. | Kenichi Nomura Kohei Fukumoto Daisuke Shimizu Takashi Okuda Naohisa Yoshida Yuri Kamitsuji Yosuke Matsumoto Hideyuki Konishi Yuji Ueda Shigeo Horiike Takeshi Okanoue Masafumi Taniwaki | 2005 | World Journal of Gastroenterology2005，11，17： | 5 |
| 2 | Recurrent chromosomal rearrangements at bands 8q24 and 11q13 in gastric cancer as detected by multicolor spectral karyotyping显示文摘AIM: To identify chromosomal translocations specific to gastric cancer (GC), spectral karyotyping (SKY) analysis was performed on established cell lines and cancerous ascitic fluids.METHODS: SKY analysis of 10 established cell lines and seven cancerous ascitic fluid samples identified recurrent chromosomal breakpoints and translocations in GC,several of which involved chromosomal loci of oncogenes or tumor suppressor genes.RESULTS: A total of 630 chromosomal breaks were identified. Chromosome no.8 was the most frequently involved in rearrangements (65 breaks), followed by chromosomes no. 11 (53), no. 1 (49), no. 7 (46), no. 13 (37), no. 3 (36), no. 17 (33), and no. 20 (29). Frequent breakpoints were detected in 8q24.1 (30 breaks), 11q13 (29), 13q14 (16), 20q11.2 (14), 7q32 (13), 17q11.2 (13),18q21 (12), 17q23 (9), 18q11.2 (9). SKY analysis identified a total of 242 chromosomal rearrangements including 190 reciprocal and non-reciprocal translocations. The recurrent combinations of chromosomal bands involved in translocations were 8q24.1 and 13q14 (3 cases), 8q24.1 and 11q13 (3), 11q13 and 17q11.2 (2), and 18q11.2 and 20q11.2 (2). Our study validated the ability of SKY to characterize in detail the chromosomal rearrangements in solid tumors and derived cell lines. Moreover,fluorescence in situ hybridization helped to identify the insertions, translocations, and homogeneously staining regions of MYCand CCND1 gene loci.CONCLUSION: The non-random co-localization of certain cytogenetic bands suggests the importance of chromosomal translocations in gastric carcinogenesis, by serving as landmarks for the cloning of GC causing genes. | Yasuhide Yamashita Kazuhiro Nishida Takashi Okuda Kenichi Nomura Yosuke Matsumoto Shoji Mitsufuji Shigeo Horiike Hiroyuki Hata Chohei Sakakura Akio Hagiwara Hisakazu Yamagishi Masafumi Taniwaki | 2005 | World Journal of Gastroenterology2005，11，33： | 4 |

| 5 | Peritoneal dissemination of pancreatic cancer caused by endoscopic ultrasound-guided fine needle aspiration:A case report and literature review显示文摘BACKGROUND Endoscopic ultrasound-guided fine needle aspiration(EUS-FNA)is a biopsy technique widely used to diagnose pancreatic tumors because of its high sensitivity and specificity.Although needle-tract seeding caused by EUS-FNA has been recently reported,dissemination of pancreatic cancer cells is generally considered to be a rare complication that does not affect patient prognosis.However,the frequency of dissemination and needle-tract seeding appears to have been underestimated.We present a case of peritoneal dissemination of pancreatic cancer due to preoperative EUS-FNA.CASE SUMMARY An 81-year-old man was referred to the Department of Surgery of our hospital in Japan owing to the detection of a pancreatic mass on computed tomography during medical screening.Trans-gastric EUS-FNA revealed that the mass was an adenocarcinoma;hence laparoscopic distal pancreatectomy with lymphadenectomy was performed.No intraoperative peritoneal dissemination and liver metastasis were visually detected,and pelvic lavage cytology was negative for carcinoma cells.The postoperative surgical specimen was negative for carcinoma cells at the dissected margin and the cut end margin;however,pathological findings revealed adenocarcinoma cells on the peritoneal surface proximal to the needle puncture site,and the cells were suspected to be disseminated via EUSFNA.Hence,the patient received adjuvant therapy with S-1(tegafur,gimeracil,and oteracil potassium);however,computed tomography performed 5 mo after surgery revealed liver metastasis and cancerous peritonitis.The patient received palliative therapy and died 8 mo after the operation.CONCLUSION The indications of EUS-FNA should be carefully considered to avoid iatrogenic dissemination,especially for cancers in the pancreatic body or tail. | Hideaki Kojima Minoru Kitago Eisuke Iwasaki Yohei Masugi Yohji Matsusaka Hiroshi Yagi Yuta Abe Yasushi Hasegawa Shutaro Hori Masayuki Tanaka Yutaka Nakano Yusuke Takemura Seiichiro Fukuhara Yoshiyuki Ohara Michiie Sakamoto Shigeo Okuda Yuko Kitagawa | 2021 | World Journal of Gastroenterology2021，27，3： | 1 |

| 8 | Successful endoscopic hemostasis for gastric arterial bleeding due to invasion of malignant lymphoma显示文摘A 75-year-old male with malignant lymphoma (ML) accompanied with gastric lesion was treated with combination chemotherapy. The patient produced tarry stool on the 4th d, and emergency gastroscopy showed arterial bleeding from the lesion. Hemostasis was achieved by injecting pure ethanol and using hemostatic clips. There is only one previous report on endoscopic hemostasis being effective for bleeding due to lymphoma. Since gastric bleeding causes significant mortality, endoscopic hemostasis should be considered as first-line treatment for ML patients who were treated with chemotherapy. | Kenichi Nomura Shinya Yamada Daisuke Shimizu Takashi Okuda Yuri Kamitsuji Naohisa Yoshida Yosuke Matsumoto Naoki Wakabayashi Kazuya Mikami Shigeo Horiike Takeshi Okanoue Masafumi Taniwaki | 2005 | World Journal of Gastroenterology2005，11，27： | 0 |
