| 1 | Risk factors for bleeding after endoscopic submucosal dissection for gastric lesions显示文摘AIM:To assess risk factors for bleeding after gastric endoscopic submucosal dissection(ESD) and to develop preventive measures.METHODS:This retrospective study was performed in a tertiary referral center.A total of 328 patients underwent ESD for 398 gastric neoplasms between July 2007 and June 2009.The main outcome was association between post-ESD bleeding and the following:age;sex;comorbidities;daily use of medicine potentially related to gastric injury/bleeding;location,size,and histological depth of lesions;ulceration;experience of operator coagulating the ulcer floor,and duration of operation.We also determined the relationship between the location of post-ESD bleeding and risk factors for hemorrhage.RESULTS:Univariate analysis revealed significant risk factors:tumor location [odds ratio(OR),2.86;95% CI:1.21-6.79,P=0.024],coagulator experience(OR,4.29;95% CI:1.43-12.86,P=0.009),and medicine potentially related to gastric injury/bleeding(OR,2.80;95% CI:1.14-6.90,P=0.039).Multivariate logistic regression analysis confirmed significant,independent risk factors:tumor in lower third of stomach(OR,2.47;95% CI:1.02-5.96,P=0.044),beginner coagulator(OR,3.93;95% CI:1.29-11.9,P=0.016),and medicine(OR,2.76;95% CI:1.09-6.98,P=0.032).We classif ied cases of post-ESD bleeding into two groups(bleeding at the ulcer margin vs bleeding at the center) and found that bleeding at the margin occurred more frequently with beginner coagulators compared with experts(OR,16.00;95% CI:1.22-210.59,P=0.040).CONCLUSION:Beginner coagulators,tumor in the antrum,and medicines were significant risk factors for post-ESD bleeding.Bleeding at the ulcer margin frequently occurred with beginner operators. | Yosuke Tsuji Ken Ohata Takafumi Ito Hideyuki Chiba Tomohiko Ohya Toshiaki Gunji Nobuyuki Matsuhashi | 2010 | World Journal of Gastroenterology2010，16，23： | 60 |
| 2 | Prospective controlled study on the effects of polyethylene glycol in capsule endoscopy显示文摘AIM:To prospectively confirm whether a small amount of polyethylene glycol(PEG)ingested after swallowing endoscopy capsule improves image quality and completion rate.METHODS:Forty-four consecutive patients referred to us for capsule endoscopy(CE)were randomized to two groups.All patients were restricted to clear fluids for 12 h before the examination.Patients in group A(22 cases)received no additional preparation,while those in group B(20 cases)ingested 500 mL of PEG within a 2 h period starting 30 min after swallowing the capsule.Clear fluids and meals were allowed 2 h and 4 h after capsule ingestion,respectively.Image quality was assessed as the percentage of visualized bowel surface area as follows:1:<25%;2:25%-49%;3:50%-74%;4:75%-89%;5:>90%.The small bowel record was divided into five segments by time,and the score for each segment was evaluated.All CE examinations were performed with the Pillcam SB capsule endoscopy sys-tem(Given Imaging Co.Ltd.,Yoqnem).RESULTS:This study ended in December 2009,because sample size was considered large enough.A total of 44 patients were enrolled.Two patients in group B were excluded from the analysis because small bowel images could not be obtained from these patients;one had a full stomach,while the other presented with a massive gastric bleed.Thus,22 patients from group A and 20 patients from group B completed the study.There was no significant difference in age(P=0.22),sex(P=0.31),and indication for CE.No significant adverse events occurred in any of the study patients.In group A,image quality deteriorated as the capsule progressed distally.However,in group B,image quality was maintained to the distal small bowel.In each of the five segments,the visibility score was significantly higher in group B than in group A(segment 1:4.3± 0.7vs 4.7±0.5,P=0.03;segment 2:4.2±0.9vs 4.8 ±0.4,P=0.01;segment 3:4.0±1.0 vs 4.6±0.7,P =0.04;segment 4:3.6±1.1 vs 4.5±0.6,P=0.003;segment 5:2.7±1.0vs 4.4±0.8,P=0.00004).Thus,the use of PEG during CE examination significantly improved image quality in all time segments,and this effect was more pronounced in the distal ileum.The completion rate to the cecum was not significantly different between groups A and B(81.8%vs 85.0%,P =0.89).There was no difference in the gastric transit time between groups(36.2±35.0 min vs 54.0±56.6 min,P=0.23),but the small bowel transit time was significantly longer in group A than in group B(246.0± 107.0 minvs 171.0±104.0 min,P=0.04).CONCLUSION:The ingestion of a small amount of PEG after the swallowing of an endoscopy capsule significantly improved CE image quality,but did not enhance the completion rate to the cecum. | Takafumi Ito Ken Ohata Akiko Ono Hideyuki Chiba Yosuke Tsuji Hajime Sato Nobuyuki Matsuhashi | 2012 | World Journal of Gastroenterology2012，18，15： | 7 |
| 3 | Y chromosome microdeletion screening using a new molecular diagnostic method in 1030 Japanese males with infertility显示文摘The azoospermia factor(AZF)region is important for spermatogenesis,and deletions within these regions are a common cause of oligozoospermia and azoospermia.Although several studies have reported this cause,the present research,to the best of our knowledge,is the first large-scale study assessing this factor in Japan.In this study,1030 male patients with infertility who were examined for Y chromosome microdeletion using the polymerase chain reaction-reverse sequence-specific oligonucleotide(PCR-rSSO)method,a newly developed method for Y chromosome microdeletion screening,were included.The study enrolled 250 patients with severe oligospermia and 717 patients with azoospermia.Among the 1030 patients,4,4,10,and 52 had AZFa,AZFb,AZFb+c,and AZFc deletions,respectively.The sperm recovery rate(SRR)of microdissection testicular sperm extraction in patients with AZFc deletions was significantly higher than that in those without AZF deletions(60.0%vs 28.7%,P=0.04).In patients with gr/gr deletion,SRR was 18.7%,which was lower than that in those without gr/gr deletion,but was not statistically significant.In conclusion,our study showed that the frequency of Y chromosome microdeletion in male patients in Japan was similar to that reported in patients from other countries,and SRR was higher in patients with AZFc deletion. | Masashi Iijima Kazuyoshi Shigehara Hideki Igarashi Koichi Kyono Yasuo Suzuki Yuji Tsuji Yoshitomo Kobori Hideyuki Kobayashi Atsushi Mizokami | 2020 | Asian Journal of Andrology2020，22，4： | 4 |

| 14 | Usefulness of continuous suction mouthpiece during esophagogastroduodenoscopy: A single-center, prospective,randomized study显示文摘AIM: To develop a new continuous suction mouthpiece(CSM) and evaluate its usefulness for screening esophagogastroduodenoscopy(EGD).METHODS: A total of 196 patients who were scheduled to undergo screening EGD were assigned to one of two groups: a group using the CSM and a group using a conventional mouthpiece. Extent of salivary flow,frequency of saliva suction, number of choking episodesduring the examination, and incidence of aspiration pneumonia after the examination were evaluated and compared between the two groups. Adverse events during and after EGD were also examined. In addition, the oral cavity was meticulously examined after the EGD.RESULTS: The same number of patients was randomly allocated to each group. There were no significant differences between the two groups in sex, age,biopsy procedure, duration of procedure and depth of sedation. Aspiration pneumonia and other significant adverse events were not observed in either group. The grade of extent of salivary flow was significantly lower in patients with the CSM than in patients with the conventional mouthpiece(P < 0.001). Although there was no significant difference, less frequent suctioning and fewer choking episodes were observed in patients with the CSM than in patients with the conventional mouthpiece(P = 0.082 and P = 0.084, respectively). In addition, there were no patients in the CSM group who required saliva suctioning during the procedure.CONCLUSION: Use of the CSM during screening EGD can reduce the extent of salivary flow. The device is expected to reduce complications and contamination with saliva. | Takao Maekita Jun Kato Yukihiko Nakatani Shotaro Enomoto Ema Takano Masahiro Tsuji Tsuyoshi Nakaya Kosaku Moribata Yosuke Muraki Naoki Shingaki Toru Niwa Hisanobu Deguchi Kazuki Ueda Izumi Inoue Mikitaka Iguchi Hideyuki Tamai Masao Ichinose | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，10： | 0 |
