type:text, Introduction: Endometriosis is a rare cause of intussusceptions in adults. Although intestinal endometriosis sometimes arises as a consequence of direct involvement of the pelvic organs with endometrial tissue, there is no report that this type of endometriosis causes ileocecal intussusception. Case presentation: Computed tomography assessment of a 40-year-old woman who presented with abdominal pain revealed ileocecal intussusceptions. The patient was managed by endoscopic reduction followed by laparoscopic resection. Adhesion between the right uterine adnexa and caecum was identified during surgery; therefore, combined resection of the uterine adnexa and ileocecum was performed. Pathological findings revealed that endometriosis, arising from the uterine tube and directly involving the cecal wall, had caused the intussusceptions. Conclusion: Although rare, endometriosis should be considered as part of a differential diagnosis of intussusception in adult women who present with abdominal pain. A preoperative diagnosis is sometimes difficult, therefore, surgical resection could be a reasonable strategy to achieve a precise diagnosis.

Also, patients with stage II CRC who are considered to be at high risk of disease recurrence often receive the same adjuvant chemotherapy treatment. We prospectively investigated the extent and degree of neuropathy suffered by stage III and high-risk stage II resectable CRC patients who underwent sequential approach involving 3 months of an oxaliplatin-based regimen followed by 3 months of capecitabine. Patients and methods: Patients with completely resected stage III and high-risk stage II CRC aged ≥20 years were eligible. Patien

type:text, An 18-year-old girl presented with abdominal pain and a tumor was subsequently detected in the jejunum. We therefore carried out a wedge resection of the jejunum. The diagnosis of GIST was confirmed histologically, and a mutation in exon 9 of the c-kit gene was observed. GISTs are rare in pediatric populations and pediatric GISTs occur predominantly in females and are characterized by a multifocal gastric location and a wild-type phenotype for the c-kit genes. The features of pediatric GISTs of the small intestine have not yet been categorized, and to date, only 11 cases in patients younger than 18 years have been reported. These cases did not occur primarily in females and tended to present as single tumors with mutations in the c-kit gene. This suggests that these cases do not have the same features as pediatric gastric GISTs, but instead are similar to adult GISTs.
