Intra-Corporeal Anastomosis Result in Quicker Return of Bowel Function/Earlier Discharge (RICART)

July 17, 2026 updated by: James W. Ogilvie, Corewell Health West

Randomized Trial of Intra-Corporeal Anastomosis for RighT Colectomies (RICART Study)

Adult patients who are regularly scheduled to undergo a right hemicolectomy via a minimally invasive approach (robotic or laparoscopic) with the creation of an anastomosis.

Detailed Description

The purpose of this trial is to investigate whether minimally invasive right colectomies done with an intra-corporeal anastomosis result in quicker return of bowel function and earlier discharge. The primary endpoint of this study will be return of bowel function as measured by passage of flatus and bowel motions. The secondary endpoints will be inpatient length of stay, incision length, postoperative narcotic use, surgical site infection (superficial, deep and organ-space), perioperative morbidity and operating room charges.

Description

Inclusion Criteria:

  • Eligible patients are those over 18 years of age who are regularly scheduled to undergo a right hemicolectomy via a minimally invasive approach (robotic or laparoscopic) with the creation of an anastomosis. Right colectomy will be defined as removal of the ascending colon, ligation of the ileocolic artery and vein, +/- removal of the terminal ileum, +/- removal of the proximal transverse colon, and +/- removal of the right branch of the middle colic artery and vein.

Exclusion Criteria:

  • Pregnant women
  • Additional colon resection is planned (i.e. left colectomy or proctectomy)
  • Vulnerable populations such as prisoners or adults unable to give consent
  • If the scheduled surgery is planned at Butterworth hospital (as to standardize the nursing care received postoperatively)
  • Emergent cases

Patients will be excluded from the study intra-operatively if:

  • The procedure is converted to an open resection
  • If a loop ileostomy is performed in addition to the right colectomy
