The surgical treatment of gastrointestinal malignancies has undergone significant development in recent years due to the introduction of innovative technologies, minimally invasive approaches, and multidisciplinary strategies. The aim of this article is to provide an overview and critical analysis of modern innovative surgical techniques used in the treatment of gastrointestinal malignancies, with a focus on their oncological outcomes, safety, and potential for clinical application.
Major areas of innovation are reviewed, including hyperthermic intraperitoneal chemotherapy (HIPEC), indocyanine green (ICG) fluorescence navigation, sentinel lymph node navigation surgery, as well as 3D modeling and the use of augmented and virtual reality technologies in preoperative planning and intraoperative navigation. Data from randomized clinical trials, systematic reviews, and meta-analyses are presented, evaluating the effectiveness of these approaches in different gastrointestinal localizations, especially gastric and colorectal carcinoma.
The analysis shows that HIPEC may offer benefits in carefully selected patients with peritoneal carcinomatosis, but it remains experimental at present due to conflicting evidence of improvement in overall survival. In contrast, ICG fluorescence navigation has demonstrated convincing results in terms of improved lymphadenectomy, better vascular visualization, and reduced postoperative complications, establishing it as a promising standard in minimally invasive gastrointestinal surgery. Sentinel lymph node navigation surgery offers the possibility of organ-sparing interventions in early gastric cancer without compromising oncological safety.
In conclusion, the integration of innovative surgical techniques, navigation technologies, and multidisciplinary approaches leads to more personalized and precise treatment of gastrointestinal malignancies, and future efforts should focus on standardization, long-term results, and high-level evidence.
