Totally Laparoscopic Ileocolic Resection with Intracorporeal Anastomosis for Crohn's Disease: A Comparative Study.

Background: Although minimally invasive surgery for Crohn's disease has been validated in previous studies, most of those reports have referred to laparoscopic-assisted procedures with an extra-corporeal anastomosis.
Objectives: To evaluate the short- and long-term outcomes of total laparoscopic ileocolic resection with an intracorporeal anastomosis for Crohn's disease patients.
Methods: We conducted a single-center retrospective review of all patients who underwent primary ileocolic resection for Crohn's disease between 2010 and 2021. Group A included 34 patients who underwent total laparoscopic ileocolic resection with intracorporeal anastomosis. Group B comprised 144 patients who underwent an open or laparoscopic-assisted procedure.
Results: No differences were noted in operative time (mean 167 minutes vs. 152 minutes, P = 0.122), length of stay (median 6.4 days vs. 7.5 days, P = 0.135), readmission rates (11.8% vs. 13.2%, P = 1), and microscopic involvement of surgical margins (7.7% vs. 18.5%, P = 0.249). Group A had significantly fewer postoperative surgical site infections (2.9% vs. 22.2% respectively, P = 0.013), with no differences in other complications prevalence. After a median follow-up of 46 months, there were similar rates of endoscopic recurrence (47.1% vs. 51.4%, P = 0.72), clinical recurrence (35.3% vs. 47.9%, P = 0.253), and surgical recurrence (2.9% vs. 4.9%, P = 0.722).
Conclusions: Total laparoscopic ileocolic resection with intracorporeal anastomosis for Crohn's disease is safe and resulted in favorable outcomes in terms of postoperative wound healing. The long-term disease recurrence rates were like those of laparoscopic-assisted and open ileocolic resection.
