Results Melena and abdominal pain were their main symptoms. The diagnosis relied upon combination of sonography, CT, gastroscopy, and endoscopic ultrasonography.

Methods Nineteen cases with negative findings of other routine inspections such as B supersonic, CT, gastric endoscopy, and colonoscopy were analyzed. Among them, there were 5 cases with abdominal pain, 2 cases with diarrhea, 7 cases with obscure gastrointestinal bleeding, 2 cases with abdominal pain and melena, and 3 cases both with abdominal pain and diarrhea. Double balloon enteroscopy was performed on these 19 cases.

19例经B超、CT、胃镜、肠镜等常规检查不能明确病因的患者，其中腹痛待查5例，腹泻待查2例，不明原因的消化道出血7例，腹痛伴有黑便2例，腹痛伴有腹泻3例，接受双气囊小肠镜检查，评价其病变检出率、并发症及患者的耐受性等。

RESULTS: In this series, 6 cases showed hematemesis, 2 showed melena and 5 showed both symptoms. All cases underwent endoscopic examination after being hospitalized; 11 cases received a positive diagnosis by endoscopy (11/13, 85%), the success rate of first endoscopic therapy was 91%(10/11), and 4 cases were treated by laparotomic surgery (4/13, 31%). Among them, definitive surgery was performed under the guidance of endoscopic hemoclipping in 2 patients who failed to be treated by endoscopy. In another 2 cases, diagnosis was missed by endoscopy and definite diagnosis was made only following exploratory operation or on the basis of pathology after the operation.

结果：13例患者临床表现为单纯呕血者6例，呕血伴黑便者5例，单纯黑便者2例，所有病例入院后均行内镜检查；其中11例经内镜确诊(11/13， 85%)，首次内镜治疗成功率为91%(10/11)。4例经手术治疗(4/13， 31%)，其中2例内镜治疗失败者在内镜钛夹指引下实施确定性手术，另2例内镜漏诊者靠手术探查或术后病理确诊。10例随访患者无1例复发。

Various factors related to patients, tumors, and treatment including PEC were investigated using univariate and multivariate analysis with regard to delayed post-ESD bleeding, evidenced by hematemesis or melena, that required endoscopic treatment.

Results The most common symptom was melena in four cases (including one case with hematemesis). Upper abdominal pain occurred in one case, and one case's mass was detected under gastroscopy. All the six cases underwent surgical operation and were confirmed by immunohistochemistry. Partial gastrectomy was performed in four cases, distal gastric curative resection in one case, and local wedgy resection in one case. All the cases survived after operation.

结果 以黑便为首发症状4例（其中1例伴呕血）；上腹疼痛1例；1例行胃镜检查时发现；全部病例均经手术治疗，切除标本经病理检查及免疫组化证实；4例行胃大部分切除术（其中2例行近端胃大部分切除＋幽门成形术，2例行远端胃大部分切除术），1例行远端胃癌根治术，1例行病灶楔形切除术。
