Background: The impact of lymph nodes (LNs) removed on the survivals of patients with stage III gastric cancer, especially on that of those who undergo the adjuvant chemotherapy as a compensation for a possibly insufficient lymphadenectomy, is still unclear.
Methods: Consecutive patients (n = 488) with stage III gastric cancer under R0 curative resection followed by adjuvant chemotherapy were analyzed. The overall survival (OS) was compared between patients with insufficient LNs removed (ILNr, <16 LNs) and sufficient LNs removed (SLNr, ≥16 LNs).
Background: Magnetic resonance imaging and endoluminal ultrasound play an important role in the restaging of locally advanced rectal cancer after preoperative chemoradiotherapy, yet their diagnostic accuracy is still controversial.
Objective: Meta-analysis was performed to estimate the diagnostic performance of MRI and endoluminal ultrasound.
Data Sources: Electronic databases from 1996 to March 2012 were searched.
Purpose: Whether the introduction of extralevator abdominoperineal excision (ELAPE) improves survival and safety remains controversial. We conducted a systematic review and meta-analysis of all comparative studies to define the efficacy and safety of ELAPE and standard abdominoperineal excision (APE).
Materials And Methods: A search for all major databases and relevant journals from inception to July 2013 without restriction on languages or regions was performed.
Background: Gut barrier failure caused by endotoxemia is a life-threatening problem. The present study aimed to determine whether any specific intestinal site is highly correlated with gut barrier failure, and whether recombinant human growth hormone (rhGH) can ameliorate gut barrier failure in a rat model of endotoxemia.
Methods: Enterostomy tubes were surgically placed in adult male Sprague-Dawley rats three days before induction of endotoxemia by lipopolysaccharide (LPS) injection.
Article Synopsis
- The study aimed to compare the safety and effectiveness of self-expanding metallic stents (SEMS) as a pre-surgical bridge versus emergency surgery for patients with left-sided malignant colorectal obstruction.
- A thorough literature search identified 14 studies with 1,083 patients, and a meta-analysis was conducted to analyze the outcomes of both methods.
- Results showed that SEMS led to lower short-term mortality and overall complications, higher resection rates, shorter operation times, and quicker recovery, indicating it is a safer and more effective option than emergency surgery.
