Sentinel node navigation in gastric cancer: new horizons for personalized minimally invasive surgical oncology?

Complete (R0) resection and regional lymph nodes (LNs) dissection represent undoubtedly the basic surgical tools for patients with gastric cancer. It is reported that the LN metastasis rate in patients with early gastric cancer (EGC) is approximately 15-20%. Therefore, the innovative clinical application of sentinel node navigation surgery (SNNS) for EGC might be able to prevent unnecessary LN dissection as well as to reduce significantly the volume of gastric resection.

Low-molecular-weight heparins and Daflon for prevention of postoperative thromboembolism.

The efficacy of low-molecular-weight heparins (LMWH) alone versus a combination of Daflon 500 mg with LMWH in preventing postoperative symptomatic thromboembolism was investigated. A total of 1372 patients aged 40 years or older undergoing major abdominal, pelvic, or abdominal wall surgery were randomized into four groups. Group A (n = 591) received enoxoparin 20 mg or fraxiparin 0.

Short-term antibiotic prophylaxis in elective colorectal surgery.

In the last 2 years, 50 patients who underwent elective colorectal surgery were prospectively studied about antibiotic prophylaxis. Two groups of 25 patients each were randomly selected. Both received: (a) a colic preparation: hypactic drugs and two enemas during the day before surgery and (b) metronidazole 0.
