Scopul acestui studiu a fost de a analiza tehnicile miniinvazive laparoscopice şi endoscopice actuale utilizate pentru rezecţia tumorilor gastrointestinale superioare.
Metode: S-a realizat o cercetare sistematică a literaturii cu privire la tehnicile hibride laparoscopice şi endoscopice în tratamentul tumorilor stromale gastrointestinale. Au fost incluse doar studiile care utilizează aceste tehnici pentru rezecţia tumorilor stromale gastrice, tumorile benigne submucoase şi cancerul gastric şi duodenal incipient. Astfel au fost identificate 25 de studii. Au fost evaluate dimensiunea şi localizarea tumorii, tipul tehnicii folosite, durata intervenţiei, tipul de închidere a defectelor peretelui visceral, pierderile de sânge, complicaţiile şi durata spitalizării.
Rezultate: Un total de 706 de pacienţi au fost operaţi miniminvaziv. Tumorile rezecate au fost tumori stromale gastrointestinale, tumori benign submucoase, cancer gastric precoce (pT1a şi pT1b) şi cancerul duodenalincipien. Tehnicile operative identificate au fost: laparoscopic endoscopic cooperative surgery (LECS), laparoscopic assisted endoscopic full thickness resection (LAEFR), clean non-exposure technique and non-exposed endoscopic wall inversion surgery (NEWS). S-au evaluat indicaţiile, caracteristicile tehnicilor şi rezultatele pe termen scurt.
Concluzie: Împreună cu tehnicile tradiţionale, noi proceduri precum LECS, LAEFR şi NEWS reprezintă o mare promisiune pentru viitorul procedurilor oncologice minim invazive.

The purpose of the study was to investigate the laparoscopic and endoscopic techniques used for the resection of upper gastrointestinal tumors.
Methods: A systematic research of the literature was performed about hybrid laparoscopic and endoscopic techniques. Only studies using these techniques for the resection of gastric stromal tumors, benign submucosal tumors and early gastric and duodenal cancer were included. 25 studies were identified. The study design, number of cases, tumor size and location, operative technique, operative time, type of closure of visceral wall defect, blood loss, complications and length of hospital stay were evaluated.
Results: A total of 706 patients were operated with this hybrid technique. The tumors resected were gastrointestinal stromal tumors, various benign submucosal tumors, early gastric cancer (pT1a and pT1b) and early duodenal cancer. The operative techniques identified were: laparoscopic endoscopic cooperative surgery (LECS), laparoscopic assisted endoscopic full thickness resection (LAEFR), clean non-exposure technique and non-exposed endoscopic wall inversion surgery (NEWS). Each technique is illustrated with the roles of the endoscopic and laparoscopic teams; the indications, characteristics and short-term results are described.
Conclusion: Along with the traditional cooperative techniques, new procedures like LECS, LAEFR and NEWS hold great promise for the future of minimally invasive oncologic procedures.
