Effective treatment of gallbladder neuroendocrine carcinoma with nivolumab.

An 89-year-old patient with gallbladder neuroendocrine neoplasms (GB-NENs) and lung cancer metastasis underwent nivolumab monotherapy, resulting in tumor shrinkage. Surgery and adjuvant nivolumab showed efficiency despite low expression of PD-L1.

A case of bladder and pelvic dead space inflammation successfully treated with endoscopic ultrasound drainage.

Key Clinical Message: Interventional endoscopic ultrasound (EUS) is effective not only for biopsy, but also for abscess drainage. We report the first use of EUS to drain inflammation of the bladder and pelvic dead space through the ileal conduit. EUS-guided drainage is effective in treating postoperative abscesses and should be employed more routinely.

The first case of splenic flexure volvulus treated with reduced port surgery using single-incision laparoscopy.

Introduction: Splenic flexure volvulus (SFV) is a rare disease. We encountered a case of SFV, caused by congenital anomalies and persistent constipation.

Case Presentation: A 43-year-old woman with a 35-year history of persistent constipation presented to the emergency department with acute lower abdominal pain.

Ascending colon stenosis caused by repeated diverticulitis that clinically mimicked advanced colon cancer: A case report.

Introduction: We experienced a rare case of right-sided large bowl obstruction (LBO) of the colon caused by chronic diverticulitis, which was challenging to diagnose.

Presentation Of Case: A young male was admitted to our department with a fever, diarrhea, and right-sided lateral abdominal pain for several days. CT showed a thickened ascending colon wall with stenosis and adjacent retroperitoneal inflammation without marked diverticula.

Two cases of splenic neoplasms with differing imaging findings that required laparoscopic resection for a definitive diagnosis.

Introduction And Importance: Splenic tumors are rare and are sometimes found incidentally. In such cases, laboratory tests and imaging studies should be performed based on the diagnostic algorithm to determine whether the tumor is benign or malignant. However, we clinicians sometimes encounter challenging cases.

The first case of POEMS syndrome with synchronous breast cancer: What are the associated diagnostic challenges?

Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, Skin changes (POEMS) syndrome is a rare plasma cell disorder that causes a paraneoplastic syndrome. We report the first case of POEMS syndrome with synchronous breast cancer. The patient was at risk of being misdiagnosed with metastatic cancer, and it is important to emphasize that physical examinations provided vital diagnostic clues.

Primary rectal diffuse large B-cell lymphoma associated with ulcerative colitis: a case report.

We need to be aware of primary intestinal lymphoproliferative disease (PILD) associated with ulcerative colitis (UC). We should carefully monitor UC patients, particularly patients who meet the following conditions; a previous Epstein-Barr virus infection, treatment duration ≧4 years, male, and age ≧50 years.
