RT Journal A1 Clay RC, Tierney NA T1 ONe-stage, en bloc resection for colonic-uterine fistula caused by diverticulitis JF JAMA JO JAMA YR 1969 FD January 20 VO 207 IS 3 SP 555 OP 557 DO 10.1001/jama.1969.03150160067018 UL http://dx.doi.org/10.1001/jama.1969.03150160067018 AB A sigmoidouterine fistula due to diverticulitis of the colon developed in one patient. This was treated by one-stage, en bloc resection of the uterus and sigmoid segment. Because of the difficulty of determining that a sigmoidouterine fistula is not due to cancer, which could be implanted in the operative field if the involved organs were separated during removal, en bloc resection when it is technically feasible seems to offer an improved chance of total recovery.
