Comparison of Postoperative and Oncologic Outcomes in Laparoscopic and Open Right Colectomy for Colon Cancer: A 5-year Experience.

Abstract

Laparoscopic colectomy is a procedure which is being performed for three decades and is gaining popularity continuously over the traditional open colectomy. This study was conducted in order to compare postoperative and oncologic results based on several factors in laparoscopic and open right colectomy for right colon cancer. This is a retrospective study of right colectomy at a single institution from 2015 until 2020. The factors that were studied included postoperative values of C-reactive protein (CRP), lactate dehydrogenase (LDH), creatine phosphokinase (CPK), the number of excised lymph nodes, the use of postoperative analgesics and the length of hospital stay. We collected data from 21 open and 17 laparoscopic right colectomies through a 5-year period. Measurements on the second postoperative day revealed mean CRP and CPK values significantly lower in the laparoscopic group compared to the open group, while LDH levels did not affirm major differences between the two groups. The mean number of lymph nodes excised during the open procedure was superior to those harvested in the laparoscopic group. The use of analgesics throughout the entire hospital stay was a combination of pethidine and tramadol for the first three postoperative days in open procedures, while paracetamol and, occasionally, tramadol were administered upon patient request following laparoscopic procedures. The mean hospital stay was substantially shorter in the laparoscopic group compared to the open surgery group. Laparoscopic right colectomy is superior compared to open right colectomy with regards to postoperative analgesia and length of hospital stay, but also in certain postoperative laboratory values. Despite these there was no supremacy considering oncologic clearance.
