Filter by:In rectal cancer surgery, the organ/space surgical site infection (O/S-SSI) has an impact on patient's prognosis. Its influence in the oncologic outcomes remains controversial. The main objective is to assess the possible effect of O/S-SSI on long-term overall survival and cancer recurrence.
Brief Summary Background The preservation of the left colic artery (LCA) during rectal cancer resection remains a topic of controversy, and there is a notable absence of robust evidence regarding the outcomes associated with LCA preservation. And the advantages of robotic-assisted laparoscopy (RAL) surgery in rectal resection remain uncertain. The objective of this study was to assess the influence of LCA preservation surgery and RAL surgery on intraoperative and postoperative complications of rectal cancer resection. Methods Participants who underwent laparoscopic (LSC) or RAL with or without LCA preservation resection for rectal cancer between April 2020 and May 2023 were retrospectively assessed. The patients were categorized into two groups: low ligation (LL) which with preservation of LCA and high ligation (HL) which without preservation of LCA. A one-to-one propensity score-matched analysis was performed to decrease confounding. The primary outcome was operative findings, operative morbidity, and postoperative genitourinary function.
This study analyzed the efficacy differences between neoadjuvant therapy and direct surgical treatment in patients with locally advanced rectal cancer in the real world. The aim was to evaluate the impact of neoadjuvant therapy on overall survival, disease-free survival, and local recurrence-free survival in patients with locally advanced rectal cancer, explore the population benefiting most from neoadjuvant therapy, and provide evidence-based medicine for the benefits of neoadjuvant therapy in patients with colorectal cancer in the real world.
The goal of this observational study is to construct a multimodal intelligent model to predict the risk of heterochronous metastasis of rectal cancer, which is helpful for individualized diagnosis and treatment and follow-up planning. The main questions it aims to answer are: - what are the independent risk factors of distant metastasis (DM) in locally advanced rectal cancer (LARC) - What is the influence weight of the above factors on the heterochronous metastasis of LARC, and how to build a risk-prediction model This study will not affect or interfere with the routine medical diagnosis and treatment of participants, and will not increase the cost and risk of participants. Participant's information is protected and identified by a unique code.
The preservation surgery of the anal sphincter has become a standard procedure for the treatment of rectal cancer and is now possible even when the tumor is close to the anus, thanks to the advancement of surgical techniques. This procedure allows patients to avoid a permanent artificial anus and enables them to evacuate through the anus, maintaining the continuity of the intestine, making it a highly preferred surgical option. Additionally, advancements in tumor treatments have led to improved long-term survival rates. However, this anal sphincter preservation surgery inevitably can cause functional abnormalities in the rectum, and around 90% of patients experience changes in bowel habits after surgery. The characteristic symptoms occurring after rectal cancer surgery, such as diarrhea, urgency of bowel movements, frequent bowel movements, and fecal incontinence, are referred to as Anterior Resection Syndrome (ARS). Particularly, symptoms following low anterior resection surgery for lower rectal cancer are termed Low Anterior Resection Syndrome (LARS). These symptoms are most severe immediately after surgery, persisting up to 1-2 years, with some improvement over time. However, in many patients, LARS can remain a lifelong challenge, significantly impacting their quality of life. Currently, there is no definitive method to treat LARS, and symptom management is achieved through empirical treatment methods or medications. Many patients with LARS experience these symptoms predominantly at night, and it is presumed that their sleep quality is severely compromised, significantly affecting their overall quality of life. However, there is a lack of research on the prevalence of such patients and the appropriate treatments for them.
This study aimed to assess efficacy of ArtiSential® in reducing laparoscopic rectal cancer surgery duration. We retrospectively reviewed the data of patients who underwent laparoscopic low or ultralow anterior resection for primary mid-to-low rectal cancer, performed by a single surgeon in 2012-2022. Patients were divided into groups, use group vs. non-use group, based on the use or non-use of the ArtiSential®. The total mesorectal excision quality and resection margin status did not differ between the groups. ArtiSential® reduced operative time without impairing surgical quality or oncologic outcomes.
HA35 (Bioactive HA or B-HA or HA35) have good tissue permeability (B-HA injection, Ministry of Health, Registration number L20200708MP07707). HA35 might not lose HA's bioactivities of binding to a variety of hyaluronan's binding proteins or receptors, including the analgesic and anticancer effects of hyaluronan, therefore being named bioactive HA or B-HA (10) (B-HA injection, Ministry of Health, Registration number L20200708MP07707).
The goal of this prospective phase II study was to determine whether personalized planning-based nCRT for LARC would indeed decrease small bowel dose, and whether selected plans, specifically prioritizing lower dose to small bowel, would result in lower rates of acute GI toxicity compared with previously reported rates.
A comprehensive study with prospectively collected data. These patients were assigned to either the taTME group or the laTME group according to the surgery procedure received
we evaluated all related clinical and pathologic data of rectal NET cases, including the resection margin status, NET grading, and lymphovascular invasion status. Finally, the present study was aimed at (1) determining the risk factors for LN and distant metastases in colorectal NETs (2) clarifying the clinical significance of the salvage treatment for colorectal neuroendocrine tumors following initial endoscopic resection with positive resection margin status and (3) compare different salvage treatment of this uncommon disease through conducting a large, multi-center cohort study.
