Robotic Laparoscopy and Endoscopy Cooperative Surgery for Primary Appendiceal Mucinous Carcinoma Masquerading as Bladder Cancer: A Case Report.

Bladder invasion by appendiceal cancer resulting in a vesico-appendiceal fistula is an uncommon occurrence. Both radical tumor removal and functional preservation of the bladder are desirable in the surgical treatment of this disease, and there are few reports on detailed surgical methods. Here, we describe a case of primary appendiceal mucinous carcinoma with bladder invasion treated with robotic laparoscopy and endoscopy cooperative surgery (RECS).

A noninvasive urinary microRNA-based assay for the detection of pancreatic cancer from early to late stages: a case control study.

Background: Pancreatic cancer is highly aggressive and has a low survival rate primarily due to late-stage diagnosis and the lack of effective early detection methods. We introduce here a novel, noninvasive urinary extracellular vesicle miRNA-based assay for the detection of pancreatic cancer from early to late stages.

Methods: From September 2019 to July 2023, Urine samples were collected from patients with pancreatic cancer (n = 153) from five distinct sites (Hokuto Hospital, Kawasaki Medical School Hospital, National Cancer Center Hospital, Kagoshima University Hospital, and Kumagaya General Hospital) and non-cancer participants (n = 309) from two separate sites (Hokuto Hospital and Omiya City Clinic).

Risk factors for local recurrence in patients with clinical stage II/III low rectal cancer: A multicenter retrospective cohort study in Japan.

Background: Identifying risk factors for local recurrence (LR) is pivotal in optimizing rectal cancer treatment. Total mesorectal excision (TME) and lateral lymph node dissection (LLND) are the standard treatment for advanced low rectal cancer in Japan. However, large-scale studies to evaluate risk factors for LR are limited.

Peritonitis After Endometrial Cytology in a Woman With Hydrosalpinx Caused by Chronic Infection.

Some women infected with (CT) are asymptomatic, while others experience lower abdominal discomfort when the inflammatory process extends to the fallopian tubes. Without treatment, salpingitis can progress to pelvic peritonitis and subsequently, peritonitis in the upper abdomen, a condition known as Fitz-Hugh-Curtis syndrome, in some cases. A nucleic acid amplification assay is required for diagnosing CT infection.

Cervical-First Approach in Thoracoscopic Esophagectomy With Intraoperative Nerve Monitoring for an Esophageal Cancer Patient With Aberrant Right Subclavian Artery.

An aberrant right subclavian artery (ARSA) is a rare vascular anomaly accompanied by nonrecurrent inferior laryngeal nerve (NRILN). Here, we described the cervical-first approach in thoracoscopic esophagectomy for an esophageal cancer patient with ARSA using the intraoperative nerve monitoring (IONM) system. First, a left cervical procedure proceeded to expose the left vagus nerve to attach the APS electrode of the IONM system, and the left cervical paraesophageal lymph nodes was dissected separately.
