An optimized machine learning model was developed to predict the risk of unplanned reoperation (uro) after anterior resection for rectal cancer, utilizing data from 2,384 patients. The Random Forest model showed exceptional performance, achieving an accuracy of 84.2% and an AUC of 0.889. Key factors influencing uro risk included tumor location, previous surgeries, and operative […]

Powered circular stapler reduces complications in colorectal surgery
The systematic review and meta-analysis encompassing five studies and 2,379 patients reveals that using powered circular staplers (PCS) significantly lowers the rates of anastomotic leak (AL) and bleeding (AB) compared to manual circular staplers (MCS), with risk ratios of 0.44 and 0.23, respectively. However, no significant differences in conversion or reoperation rates were observed. The […]
A new classification improves outcomes for hepatocellular carcinoma patients
A novel resectability classification for hepatocellular carcinoma (HCC) categorizes patients into resectable, borderline resectable, and unresectable groups. Analysis of 409 patients showed that those classified as borderline demonstrated significantly worse progression-free and overall survival compared to resectable patients, with p-values indicating strong significance (p < 0.0001). This classification aids in predicting outcomes and may inform […]
Transoral robotic thyroidectomy shows favorable outcomes in 1,000 cases
A cohort of 1,000 patients undergoing transoral robotic thyroidectomy demonstrated promising results, particularly in cosmetic outcomes and postoperative recovery. The most common procedure was lobectomy (89.4%), with minimal complications (3.6%) and manageable postoperative pain scores. Average hospital stays were 2.6 days, and no recurrence was noted during a median follow-up of 39 months. A discernible […]
AI model predicts futility of surgery in cholangiocarcinoma patients
An artificial intelligence model effectively predicted “futile” surgeries in intrahepatic cholangiocarcinoma patients, utilizing ten preoperative factors. In a study of 827 cases, 378 (45.7%) experienced insufficient surgical outcomes, with notable rates of recurrence (78.6%) and mortality (21.4%) within 12 months. The model achieved high accuracy, with a training area under the curve of 0.830 and […]
Significant research trends in frailty and surgery identified
A comprehensive bibliometric analysis conducted from 1978 to 2024 highlights the extensive global research on perioperative frailty, involving 4,119 published papers by 21,879 authors from 95 countries. The United States leads in publication volume, with the University of California system producing the most papers. Key research areas identified include preoperative risk assessment, postoperative complications, and […]
Laparoscopic surgery shows advantages for gastrointestinal perforations
In a study involving 219 patients, laparoscopic surgery for lower gastrointestinal perforations demonstrated significant advantages over open surgery. Median operative time was reduced (126 vs. 146 minutes), with far less intraoperative blood loss (50.4 ml vs. 400.1 ml). Patients undergoing laparoscopic procedures had a lower rate of postoperative complications (20% vs. 66.5%), particularly wound infections […]
Preoperative oral nutritional supplements improve outcomes for gastrointestinal cancer surgery
A systematic review and meta-analysis of 12 studies involving 1,201 patients revealed that preoperative oral nutritional supplements (ONS) significantly reduce infectious complications and improve nutritional and immune status in gastrointestinal cancer patients. Key findings included a reduction in white blood cell count and C-reactive protein levels, alongside improved albumin and prealbumin levels. However, no significant […]
EUS-FNA/B shows strong diagnostic performance for PANNETs
A meta-analysis involving 2,978 patients confirms that endoscopic ultrasound-guided fine needle acquisition (EUS-FNA/B) is an effective method for diagnosing and pre-operatively grading pancreatic neuroendocrine tumors (PANNETs). The overall concordance rate with surgical grading was 0.77, with a notable increase in the G1 subgroup (0.88). Notably, fine needle biopsy (FNB) outperformed fine needle aspiration (FNA) in […]
Class III obesity increases postoperative risks in emergency surgery.
Findings indicate that class III obesity significantly correlates with adverse postoperative outcomes in emergency general surgery. Out of 78,578 patients analyzed, the risk of 30-day postoperative morbidity escalates with rising obesity classes, particularly highlighting class III obesity as a key risk factor (adjusted odds ratio of 1.14). Additionally, patients with higher obesity classes experienced increased […]
