Impact of the Specific Extraction-Site Location on the Risk of Incisional Hernia After Laparoscopic Colorectal Resection

A novel robotic right colectomy for colon cancer via the suprapubic approach using the da Vinci Xi system: initial clinical experience

Purpose

We developed a technique of totally-robotic right colectomy with D3 lymphadenectomy and intracorporeal anastomosis via a suprapubic transverse linear port. This article aimed to introduce our novel robotic surgical technique and assess the short-term outcomes in a series of five patients.

Methods

All colectomies were performed using the da Vinci Xi system. Four robot trocars were placed transversely in the supra pubic area. Totally-robotic right colectomy was performed, including colonic mobilization, D3 lymphadenectomy, and intra corporeal stapled functional anastomosis. The 2 middle suprapubic trocar incisions were then extended to retrieve the specimen.

Results

Five robotic right colectomies via the suprapubic approach were performed between August 2015 and February 2016. The mean operation time was 183 ± 29.37 minutes, and the mean estimated blood loss was 27 ± 9.75 mL. The time to clear liquid intake was 3 days in all patients, and the mean length of stay after surgery was 6.2 ± 0.55 days. No patient required conversion to conventional laparoscopic surgery. There were no perioperative complications. According to the pathology report, the mean number of harvested lymph nodes was 36.6 ± 4.45. Four patients were stage III, and 1 patient was stage II according to the 7th edition of the American Joint Committee on Cancer system.

Conclusion

Totally-robotic right colectomy via the suprapubic approach can be performed successfully in selected patients. Further comparative studies are required to verify the clinical advantages of our technique over conventional robotic surgery.

Incisional hernia prevention using a cyanoacrilate-fixed retrofascial mesh

INTRODUCTION

The rate of incisional hernia in high-risk patients (obesity, cancer, etc.) is high, even in laparoscopic surgery. The aim of this study is to evaluate the safety of the use of cyanoacrylate fixed prophylactic meshes in the assistance incision in overweight or obese patients undergoing laparoscopic colorectal surgery.

METHODS

A prospective, non-randomized cohort study of patients undergoing elective laparoscopic resection for colorectal cancer between January 2013 and March 2016 was performed. Those with a body mass index greater than 25kg / m² were evaluated to implant a prophylactic meshes fixed with cyanoacrylate (Histoacryl®) as reinforcement of the assistance incision.

RESULTS

52 patients were analyzed (mean body mass index: 28.4±2kg / m ²). Prophylactic meshes was implanted in 15 patients. The time to put the mesh in place was always less than 5minutes. There was no significant difference in wound infection rate (12% vs. 10%). No mesh had to be explanted. Although the mean follow-up was shorter (14.1±4 vs. 22.3±9 months), there were no incisional hernia in the mesh group. On the other hand, in the non-mesh group, 1 acute evisceration (2.7%) and 4 incisional hernia of the assistance incision were observed (10.8%). There were no significant differences between groups regarding trocar incisional hernia (6.6 vs. 5.4%).

CONCLUSIONS

The implantation of a reinforcement prophylactic mesh in overweight or obese patients undergoing laparoscopic colorectal surgery is safe and seems to reduce the short-term rate of incisional hernia. Fixation with cyanoacrylate is a rapid method that facilitates the procedure without additional complications.
