Validation of 3D virtual modelling (3DVM) demonstrated a 96% accuracy for identifying arteriovenous variations in laparoscopic complete mesocolic excision with central vascular ligation (CMECVL) among 26 patients. Compared to 49 standard mesocolic excision controls, CMECVL showed no intraoperative complications and similar 30-day morbidity rates, although intraoperative times were longer initially. Aimed at improving surgical safety, […]

Sugarbaker technique shows lower recurrence in parastomal hernia repair
Findings from a retrospective analysis of 81 patients reveal a 25.9% recurrence rate and a 16.0% complication rate for large parastomal hernia repairs using lap-re-do techniques. Notably, the lap-re-do Sugarbaker technique demonstrated a significantly lower recurrence rate of 12.2% compared to 40% for the Keyhole technique. Complication and reoperation rates were also more favorable with […]
Robotic-assisted NOSE offers superior outcomes in colorectal surgery
This meta-analysis compared robotic-assisted natural orifice specimen extraction (NOSE) with traditional robotic transabdominal wall specimen retrieval (TWSR) in colorectal cancer surgeries involving 717 patients. Findings revealed that the NOSE technique resulted in significantly lower overall postoperative complications (OR 0.55; p=0.01) and indicated its safety and effectiveness as an alternative to TWSR. Enhanced recovery metrics were […]
Computer vision algorithm outperforms experts in predicting SMA margin status.
A computer vision algorithm was developed to predict superior mesenteric artery (SMA) margin status in pancreatic ductal adenocarcinoma patients using preoperative CT scans. In a study involving 200 patients, the algorithm achieved a sensitivity of 0.43, outperforming radiologists (0.23) and surgeons (0.36). Specificity was high across the board, with both the algorithm and a radiologist […]
Preoperative hypoalbuminemia increases mortality and complications post-esophagectomy.
Preoperative hypoalbuminemia is linked to higher 30-day mortality and complications after esophagectomy. In a study involving 803 patients with hypoalbuminemia compared to 7046 controls, matched analyses revealed mortality rates of 4.48% for those with low albumin versus 3.00% for those without. Findings suggest that recognizing and addressing preoperative hypoalbuminemia may be a cost-effective risk stratification […]
CT-based radiomics model effectively predicts fibrosis in PDAC patients
The study established tumor fibrosis as an independent prognostic factor for survival in pancreatic ductal adenocarcinoma (PDAC) patients, identifying a 40% collagen fraction cut-off value crucial for prognosis differentiation. Utilizing a CT-based radiomics model, researchers achieved areas under the curve of 0.825 and 0.745 in training and test cohorts, respectively, outperforming traditional models in predicting […]
Complete pathologic response significantly enhances survival in esophageal adenocarcinoma
Achieving complete pathologic response in esophageal adenocarcinoma is linked to a notable survival benefit. Among 16,169 patients analyzed, 11.4% achieved this response, rising to 17.5% in those diagnosed from 2016 to 2020. Key independent predictors included female sex, black race, Hispanic ethnicity, and clinical stage II disease, while clinical stage III correlated with lower response […]
Colorectal cancer imposes significant economic burdens on society.
A systematic review of 37 studies highlights that colorectal cancer incurs substantial direct and indirect costs, primarily driven by direct medical expenses such as hospitalization, surgery, and chemotherapy. Face significant financial impacts are experienced by families, the health system, and broader society. The findings advocate for preventive measures and lifestyle modifications to alleviate this economic […]
Transrectal drainage tubes effectively reduce postendoscopic submucosal dissection complications
A multicenter randomized controlled trial evaluated the efficacy of transrectal drainage tubes (TDTS) in preventing postendoscopic submucosal dissection (PECS) in 224 patients. The results showed a significantly lower incidence of PECS in the TDT group (6.25%) compared to the non-TDT group (17.86%), with a relative risk of 0.350 (p = 0.008). Subgroup analyses indicated that […]
Pancreas-guided technique enhances laparoscopic colon surgery efficiency
The pancreas-guided splenic flexure mobilization technique demonstrated significant benefits during laparoscopic left hemicolectomy compared to the classic approach. The mean surgical duration and intraoperative blood loss were notably lower in the pancreas-guided group (p < 0.01). Additionally, no retro-pancreatic space penetrations occurred in this group, contrasting with 4.3% in the classic group (p < 0.05). […]
