Standardized robotic D3-D4 lymphadenectomy improves survival in upper rectum and sigmoid colon cancer patients with more than N2 lymph node metastasis. Specific nodal stations contribute differently to overall survival, with common iliac vessels and infra-renal vein being significant predictors. Results suggest optimized surgical techniques and…
Researchers developed and validated machine learning (ML) models to predict the difficulty of laparoscopic total mesorectal excision (LaTME) in rectal cancer. In a study with 186 patients, four ML models—logistic regression (LR), support vector machine (SVM), random forest (RF), and decision tree (DT)—were developed using…
Clinicians developed a preoperative checklist to support clinical risk assessment and patient selection for patients with ulcerative colitis considering ileoanal pouch surgery (IPAA). The checklist includes risk factors such as gender, advanced age, obesity, comorbidities, sphincteric impairment, Crohn's disease, and pelvic radiation therapy. It also…
Effective maintenance therapies for Crohn's disease post-surgery include 5-aminosalicylic acid, adalimumab, and thiopurine analogues. Cochrane reviews show these agents have varying levels of efficacy in preventing recurrence after surgery, with 5-ASA being probably more effective than placebo and adalimumab showing promise in network meta-analysis. Clinicians…
Researchers used machine learning (ML) to quantify cumulative ileal injury on CT-enterography (CTE) scans for patients with ileal Crohn's disease (CD) to predict future bowel surgery. Analysis of 229 CTE scans with 8,424 mini-segments revealed strong agreement between ML and radiologists in grading bowel injury…
The study evaluated the effectiveness of endoscopic ultrasound (EUS) in predicting colorectal invasion in patients with pelvic masses. EUS showed high diagnostic accuracy with sensitivity of 83.3% and specificity of 97.8%. It is recommended for preoperative diagnosis by gynecologists to determine suitable surgical methods and…
Researchers conducted a multicenter prospective study to assess remote programming's effectiveness and patient satisfaction in stage I sacral neuromodulation (SNM). A total of 63 participants from 6 centers were divided into remote programming (RP) and outpatient control (OC) groups. The RP group showed high usability…
A nomogram incorporating treatment data proved better than the AJCC staging system in predicting overall survival for gastroenteropancreatic neuroendocrine tumors. Key factors include sex, age, race, tumor location, and treatment modalities. Internal and external validation showed superior performance, advocating for individual risk evaluation to enhance…
Researchers conducted a retrospective review of 394 microwave ablation (MWA) procedures on 328 patients with colorectal liver metastasis. The study found a low morbidity rate, with Clavien-Dindo grade III or IV complications occurring in 3.6% of patients, all of whom had concomitant procedures. Incomplete ablation…
Conversion from minimally invasive surgery to open surgery in colon cancer patients resulted in higher overall survival compared to upfront laparotomy. This survival advantage was particularly notable in patients over 65 years old, those with significant comorbidities, and individuals with left-sided tumors. Minimally invasive surgery…
