Long-term results of laparoscopic colorectal cancer resection.

No abstract

Laparoscopic right colectomy with D3APEM is feasible, associated with acceptable morbidity and fast recovery; now in readiness for introduction in specialized colorectal institutions.

In Natural Orifice Transluminal Endoscopic Surgery (NOTES), the procedures are performed through natural body openings, such as the mouth, vagina, urtehra and anus. By avoiding skin incisions, it is possible to prevent scars, hernias and wound infections. NOTES in humans should at this point in time only be performed within approved clinical studies.

Aims: The treatment of gastric cancer has changed in the western countries during the last decade. This includes multidisciplinary team (MDT) meetings, perioperative chemotherapy, extended lymph node dissection, and laparoscopic surgery, all of which were gradually implemented at our department from 2008. The aim of the present study was to determine the effect of these changes on morbidity and survival. Material and Methods: 185 patients with gastric cancer were operated with curative intent from 2000 until 2016 in this retrospective, observational, follow-up study; 83 before implementation of modern principles in 2008 (period 1) and 102 were treated after 2008 (period 2). Results: The resection rate (94% vs 92.8%) and mortality rates (4.8% vs 2.9%) did not differ between the two periods. In period 2, 48 patients (47.1%), received neoadjuvant chemotherapy. In 36 patients (35.3%), laparoscopic surgery with D2 lymphadenectomy was performed. There was a significantly higher yield in the number of lymph nodes in period 2 compared to period 1 (14 vs 8, p < 0.001). This is also apparent between laparoscopic and open The five-year survival rate was significantly improved after the change in treatment principles with an estimated improvement from 30% to 40% between the periods (p = 0.033). Conclusion: The combined effect of MDT meetings, neoadjuvant chemotherapy, extended lymphnode dissection and laparoscopy has improved the prognosis of gastric cancer patients.
