Background: Endoscopic sphincterotomy (ES) for bile duct stones (BDS) can cause basket impaction with stone, complicating the procedure. In this study, we evaluated the utility and safety of small incision ES combined with endoscopic papillary balloon dilation (sES + EPBD) (balloon dilated up to the stone size), compared with ES alone for BDS <12 mm.
Methods: The primary endpoint was the frequency of mechanical lithotripsy (ML), indicating the risk of basket impaction with stone; however, the secondary endpoints were procedure time, successful stone removal, and early adverse events.
Co-infections with human papillomavirus (HPV) of multiple genotypes mainly occur due to increased sexual activity. To address the prevalence and trend of HPV co-infections in Japan, HPV-type-specific data from Japanese women (n = 8128) aged < 40 years and newly diagnosed with cervical abnormalities at 24 hospitals between 2012 and 2023 were analyzed. These included cervical intraepithelial neoplasia grade 1/2 (CIN1/2, n = 2745), CIN3/adenocarcinoma in situ (AIS) (n = 3953), and invasive cervical cancer (ICC, n = 1430).

- The study aimed to explore the impact of adjuvant chemotherapy on survival rates in patients diagnosed with stage I uterine leiomyosarcoma (uLMS).
- A systematic review of 16 studies, involving nearly 5,700 patients, found that adjuvant chemotherapy was used by about 38.5% of patients but showed no significant difference in overall survival or disease-free survival compared to those who received observation only.
- Despite a variety of chemotherapy regimens being assessed, including drugs like doxorubicin and cisplatin, results indicated no clear survival advantage from using adjuvant chemotherapy in these patients.
Background: Mature cystic teratomas or dermoid cysts of the pancreas complicate surgical approaches because of their anatomical position and ever-growing size. Herein, we report a case of a giant mature cystic teratoma of the pancreas that was successfully resected via complete laparoscopic distal pancreatectomy (LDP).
Case Presentation: A 39-year-old female patient was referred to our hospital for the evaluation of a pancreatic tumor.
Objectives: Most of the pancreatic cyst protrusions detected by B-mode endoscopic ultrasound (BM-EUS) are nonneoplastic and are not enhanced by contrast-enhanced EUS (CE-EUS) using ultrasound contrast agent (USCA). This study aimed to identify useful findings for distinguishing between neoplastic and nonneoplastic pancreatic cyst protrusions on BM-EUS to facilitate efficient USCA use.
Materials And Methods: A total of 151 pancreatic cyst protrusions in 119 consecutive patients who underwent CE-EUS were analyzed.
