A surgical solution to regain bowel continuity following an extended left colectomy—reviving and extending the indication for a “Flip-Flop” procedure

Background and aims Extended left hemicolectomy might be necessary for several indications. Once the resection is completed, it would be difficult or impossible to anastomose the transverse colon to the rectum due to the difficulty in mobilizing the transverse colon to reach for a tension-free rectal anastomosis. The aim of this report is to present the “Flip-Flop” technique to overcome this challenging situation. The procedure is based on a surgical technique published in the early 1960s to avoid permanent stoma after proctectomy and consists of changing the location of the right colon to reach the rectum. Methods Clinical parameters, surgical aspects, and postoperative outcome of patients that underwent the flip-flop procedure following an extended left colectomy in our medical service was reviewed. Results Three patients underwent a flip-flop procedure after an extended left colectomy performed for various reasons. The surgical technique is detailed in a step by step manner. Patients had uneventful postoperative recovery with an adequate functional outcome. Conclusions We believe that this approach should be revived and be considered also in cases when the full length of the rectum is preserved to avoid ileo-rectal anastomosis or a high-tension colocolonic anastomosis. Popularization of this surgical solution among surgeons is highly important.
