A systematic review and network meta-analysis identified eight effective interventions for preventing postoperative esophageal stenosis following endoscopic resection of superficial cancer. Notable approaches included the combination of polyglycolic acid with a steroid and botulinum toxin. These interventions also led to significant reductions in the number of endoscopic balloon dilatation sessions needed. Importantly, none of the […]

Laparoscopic surgery shows benefits for metachronous colorectal cancer patients
In a comparative study of 59 patients with metachronous colorectal cancer, laparoscopic surgery demonstrated significant advantages over open surgery. Patients who underwent laparoscopic procedures experienced less blood loss (56.80 ml vs. 136.47 ml), faster recovery of bowel function, and shorter hospital stays (7.24 days vs. 10.79 days). Additionally, those in the laparoscopic group returned to […]
Tumor-Stroma Ratio Accurately Predicts Peritoneal Metastasis in Gastric Cancer
Analysis reveals a strong correlation between tumor-stroma ratio (tsr) and peritoneal metastasis (pm) in gastric cancer patients. The study included 640 patients across several cohorts, establishing a diagnostic model integrating tsr with CA125, CA724, and Borrmann type. The model demonstrated robust predictive capabilities, achieving an area under the curve (AUC) of 0.85 in the training […]
Transanal TME shows equivalent disease-free survival compared to laparoscopic TME.
In a study involving 1,115 patients with mid-low rectal cancer, transanal total mesorectal excision (TME) demonstrated a 3-year disease-free survival rate of 82.1%, while laparoscopic TME showed 79.4%, indicating noninferiority. The local recurrence rates were 3.6% and 4.4%, respectively. Additionally, overall survival rates were 92.6% for transanal TME and 90.7% for laparoscopic TME. These findings […]
Outcomes of Pelvic Pouch Procedure Highlight Risks and Survival Rates
Over a 40-year analysis involving 5,070 patients, significant differences in pouch survival rates were observed among various diagnoses. Ulcerative colitis (UC) had a 20-year survival rate of 92%, while Crohn’s disease (CD) was lower at 87%. Patients with familial adenomatous polyposis (FAP) exhibited the best outcomes, with a 95% survival rate and fewer complications. However, […]
Gallbladder and biliary tract cancer incidence continues to rise.
Between 1990 and 2021, gallbladder and biliary tract cancer (GBTC) saw a substantial increase, with new cases rising by 101.09% and deaths by 74.26%. In 2021, there were approximately 216,768 new cases and 171,961 deaths globally, predominantly affecting females and older adults. Although age-standardized incidence and death rates have trended downward over the years, projections […]
Preoperative ctDNA status predicts recurrence risk in esophageal cancer
Preoperative circulating tumor DNA (ctDNA) analysis shows significant prognostic value in patients with esophageal squamous cell carcinoma (ESCC) undergoing neoadjuvant chemotherapy followed by surgery. Among 25 patients, those with ctDNA detected post-treatment faced a recurrence-free survival rate of only 8% at 36 months, compared to 92% for ctDNA-negative patients (p < 0.001). These findings highlight […]
Significant research waste identified in gastroesophageal trials
Over the past 20 years, an analysis of 182 randomized controlled trials (RCTs) on gastroesophageal reflux disease and hiatal hernia highlighted that over 86.7% exhibited significant research waste. The majority of trials were drug-related, primarily conducted in North America and Asia, with deficiencies found in various aspects such as reporting adequacy and design flaws. This […]
Necrosis extent and QNI classification predict step-up needs.
A study of seventy patients undergoing EUS-guided drainage revealed that 35.7% required step-up procedures, mainly endoscopic necrosectomy. Independent predictors included necrosis ≥60% and classification in the high-risk Quadrant Necrosis Infection (QNI) group. Clinical success was high, at 92.9%, with those in the high-risk group experiencing longer hospital stays. EUS evaluations showed a tendency to overestimate […]
Preoperative tumor markers predict surgical outcomes in peritoneal metastases
Clustering preoperative tumor marker patterns aids in predicting surgical outcomes for patients with peritoneal metastases. Among 138 with pseudomyxoma peritonei (pMP), two distinct clusters emerged—pMP cluster-1 had a 5-year overall survival rate of 77%, while pMP cluster-2 faced a significantly poorer prognosis of 36%. A similar pattern was observed in 213 colorectal peritoneal metastases patients, […]
