Article Abstract
Background: There are a few cases of lateral lymph node (LLN) metastasis (LLNM) of T1 rectal cancer. Moreover, LLNM is easily missed, especially in patients with early-stage rectal cancer. To our knowledge, the possibility of bilateral LLNM before surgery has not been reported in previous studies.
Case Summary: A 36-year-old woman underwent endoscopic submucosal dissection at a local hospital owing to a clinical diagnosis of a rectal polyp. The pathology report showed a diagnosis of T1 rectal mucinous adenocarcinoma. She was considered to have bilateral LLNM after the examination at our hospital. Laparoscopic total mesorectal excision plus bilateral LLN dissection was performed and the pathological outcomes indicated unilateral LLNM. The patient received long-course adjuvant chemoradiotherapy with no recurrence or metastasis observed during the 1-year follow-up period.
Conclusion: T1 rectal cancer could lead to LLNM and possibly, bilateral LLNM. Therefore, adequate clinical evaluation is essential for these patients.

Persistent high-risk human papillomavirus (hHPV) infection, especially HPV-16, plays a central role in the development of high-grade squamous intraepithelial lesions (HSIL). This study aimed to evaluate the performance of co-testing (cytology and hHPV detection) in a real-world cohort of men who have sex with men (MSM) and transgender women (TW) living with HIV. We conducted a prospective study (2017-2023) at a tertiary care center in Spain.

Solitary rectal ulcer syndrome (SRUS) is an uncommon, benign condition that presents with a wide range of symptoms mimicking other pathological conditions, often leading to misdiagnosis and delays in treatment. A 60-year-old male patient was diagnosed with SRUS with rectal stricture with the help of colonoscopy, anorectal manometry, magnetic resonance defecography, and histopathological examination. He was managed with high-fiber diet, laxatives, biofeedback therapy, argon plasma coagulation, and stricture dilatation, which effectively alleviated the patient's condition.

Methods: Using data from the Japanese National Clinical Database, we analyzed 109 754 low anterior resection cases between January 2018 and December 2023, categorized into pre-pandemic (February 2020 and earlier), pandemic (March 2020-April 2023), and post-pandemic (May 2023 onward) periods. Trends in the number of low anterior resection cases, postoperative intensive care unit utilization, and complications, including anastomotic leakage and pneumonia, were examined.
