Purpose:
We evaluated the perioperative inflammatory mediators in a right hemicolectomy performed with single-incision laparoscopic surgery (SILS) and traditional multi-port laparoscopic surgery (MLS) to compare the postoperative inflammatory response and feasibility of SILS with that of MLS.
Methods:
In this retrospective study, we enrolled 56 consecutive colorectal cancer patients who underwent right hemicolectomy prospectively. Twenty patients underwent SILS, and 36 underwent MLS. The preoperative and postoperative levels of plasma vascular endothelial growth factor (VEGF), serum interleukin-6 (IL-6), and C-reactive protein (CRP) as well as the number of platelet cells were measured in all patients. The operation duration, number of harvested lymph nodes, length of the resected bowel, blood loss, and duration of hospital stay were also compared between the two groups.
Results:
Neither SILS nor MLS had any conversion cases. The operation duration was longer for MLS than for SILS. Blood loss tended to be lower among patients who underwent SILS than among those who underwent MLS. However, the number of harvested LNs was significantly lower with SILS than with MLS. In both pre- and postoperative blood examinations, there was no marked difference in inflammatory mediators between MLS and SILS.
Conclusion:
There was no systemic inflammatory advantage associated with SILS compared with MLS.
Insights
Single-incision laparoscopic surgery (SILS) for right hemicolectomy showed no systemic inflammatory advantage over traditional multi-port laparoscopic surgery (MLS). Both techniques demonstrated feasibility, but SILS had fewer harvested lymph nodes.
Area of Science:
- Colorectal Surgery
- Minimally Invasive Surgery
- Surgical Oncology
Background:
- Single-incision laparoscopic surgery (SILS) is an evolving minimally invasive technique.
- Comparing SILS with traditional multi-port laparoscopic surgery (MLS) is crucial for understanding its clinical benefits.
- Inflammatory response is a key indicator of surgical stress and recovery.
Purpose of the Study:
- To compare the perioperative inflammatory mediators between SILS and MLS for right hemicolectomy.
- To evaluate the feasibility and postoperative inflammatory response of SILS versus MLS.
- To assess key surgical outcomes including operation duration, blood loss, and lymph node harvest.
Main Methods:
- Retrospective analysis of 56 consecutive patients undergoing right hemicolectomy.
- Comparison between 20 patients in the SILS group and 36 patients in the MLS group.
- Measurement of plasma vascular endothelial growth factor (VEGF), serum interleukin-6 (IL-6), C-reactive protein (CRP), and platelet count pre- and postoperatively.
Main Results:
- No conversions to open surgery in either group.
- SILS was associated with a longer operation duration but potentially lower blood loss compared to MLS.
- No significant differences in perioperative inflammatory mediators (VEGF, IL-6, CRP) were observed between SILS and MLS groups.
- Significantly fewer lymph nodes were harvested in the SILS group.
Conclusions:
- Single-incision laparoscopic surgery (SILS) does not offer a systemic inflammatory advantage over multi-port laparoscopic surgery (MLS) for right hemicolectomy.
- While feasible, SILS may compromise lymph node retrieval compared to MLS.
- Further research is needed to optimize SILS techniques for oncologic adequacy.
