Stapled transperineal rectovaginal fistula repair for low- and mid-level rectovaginal fistulas: A comparison study with rectal mucosal advancement flap repair.

Background: As an innovative treatment, stapled transperineal rectovaginal fistula repair (STR) for rectovaginal fistula (RVF) has demonstrated effectiveness in preliminary reports. This study aims to compare STR with rectal mucosal advancement flap repair (RAF), a widely utilized surgical procedure, for the surgical outcome of the low- and mid-level RVF.

Methods: In this retrospective cohort study, patients with low- and mid-level RVF who underwent STR or RAF were included from both the Sixth Affiliated Hospital of Sun Yat-sen University and Xi'an Daxing Hospital.

Association between Dietary Inflammatory Index and Risk of Colorectal Adenomatous Polyps in Kashgar Prefecture of Xinjiang, China.

Malignant colorectal tumors and precancerous lesions are closely associated with chronic inflammation. Specific dietary patterns can increase chronic inflammation in the body, thereby promoting the occurrence of tumors and precancerous lesions. We have conducted a case-control study in Kashgar Prefecture, Xinjiang, China, to explore the association between the energy-adjusted dietary inflammatory index (E-DII) and the risk of colorectal adenomatous polyps (CAP).

Single-Cell RNA Sequencing Reveals Heterogeneity in the Tumor Microenvironment between Young-Onset and Old-Onset Colorectal Cancer.

Background: The incidence of sporadic young-onset colorectal cancer (yCRC) is increasing. Compared with old-onset colorectal cancer (oCRC), yCRC has different clinical and molecular characteristics. However, the difference in the tumor microenvironment (TME) between yCRC and oCRC remains unclear.

Mucocele: a rare complication following stapled haemorrhoidopexy.

Background: Stapled haemorrhoidopexy (SH) has resulted in a unique collection of procedural complications with postoperative mucocele a particularly rare example. This study is designed to comprehensively describe the characteristics of rectal mucocele and discuss its pathogenesis following SH surgery.

Methods: A database of patients presenting with a rectal mucocele following an SH procedure was established and studied retrospectively.

Comparison of seven screening methods in the diagnosis of bladder cancer.

Background: We compared the validity (evaluated by sensitivity and specificity), reliability (evaluated by reproducibility) and yield (evaluated by predictive value, examining complexity and cost) of individual and combined tests for bladder tumour antigen stat (BTAstat), nuclear matrix protein 22 (NMP22), hyaluronic acid (HA), survivin, CD44v6, vascular endothelial growth factor (VEGF), and voided urine cytology (VUC) in detecting bladder cancer. And at the same time we evaluated the clinical value of these seven detecting methods in the diagnosis of bladder cancer.

Methods: The six markers and VUC were detected in the urine of cancer group (151 patients with bladder cancer) and two control groups (50 patients with benign urological diseases and 50 healthy controls).
