Contrast-enhanced ultrasound enhances survival in liver metastases

In a study involving 130 patients with unresectable colorectal cancer liver metastases, the use of contrast-enhanced intraoperative ultrasound (ce-ious) significantly improved hepatic recurrence-free survival rates compared to standard intraoperative ultrasound alone. Specifically, the ce-ious group demonstrated a lower recurrence rate (hazard ratio 0.55), especially in those with bilobar metastases, fewer than three tumors, or extrahepatic […]

Neoadjuvant chemotherapy shows promise for survival in rectal cancer

A national database study of locally advanced rectal adenocarcinoma patients reveals that neoadjuvant chemotherapy (NAC) combined with chemoradiation (CRT) leads to better overall survival (OS) outcomes than CRT alone. Those receiving NAC alone exhibited poorer pathologic outcomes, specifically lower rates of R0 resection and pathologic complete response. The results underscore the potential benefits of an […]

Intracorporeal anastomosis enhances recovery in laparoscopic surgeries

A systematic review of 720 patients revealed that while intracorporeal and extracorporeal anastomosis in laparoscopic right hemicolectomy presented no significant differences in anastomotic leakage (RR 0.93), the former showcased notable advantages. Intracorporeal anastomosis led to reduced postoperative ileus and surgical site infections, alongside quicker bowel function recovery and shorter hospital stays. This suggests that intracorporeal […]

MRI effectively assesses peritoneal cancer index in patients.

Results indicate that diffusion-weighted MRI (dw-MRI) demonstrates significant accuracy in evaluating the peritoneal cancer index (PCI) in colorectal cancer patients with peritoneal metastases. In a cohort of 87 patients, a strong correlation was found between MRI-derived PCI and histopathology (0.77), with surgical PCI showing excellent agreement with histopathology at 0.87. These findings support MRI’s potential […]

HALP score effectively predicts complicated acute diverticulitis

In a study involving 190 patients, the HALP score demonstrated significant potential in assessing the severity of acute diverticulitis. Key inflammatory markers and HALP scores were notably higher in complicated cases compared to uncomplicated ones, indicating robust prognostic value. ROC analysis revealed that the HALP score can reliably identify disease complexity, achieving an AUC of […]

Machine learning model predicts unplanned reoperation risk in rectal cancer

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 […]

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 […]

Minimum Ablative Margin of 5 mm Ensures Optimal Outcomes

A multicentre study on colorectal liver metastases establishes that an intraprocedural minimum ablative margin of at least 5 mm significantly reduces the risk of local disease progression. With data from 400 ablated tumors across various institutions, findings reveal 3-year progression rates drop to below 1% when margins exceed 4.6 mm. The results substantiate the proposed […]

Enhanced recovery protocols significantly reduce delayed recovery rates

Identifying key factors impacting recovery, clinicians analyzed data from 1,535 patients undergoing elective colorectal surgery across 22 hospitals. Despite a median adherence to protocols at 75%, 31.7% experienced delayed recovery. The study highlighted six critical protocol items, including pre-admission counseling and early removal of the nasogastric tube, which independently improved recovery outcomes. Notably, adherence to […]
