OBJECTIVE. The purposeof this studywas to determinethe usefulnessof contrast-en hanced radiography of the Hartmann's pouch for evaluating postoperative abnormalities.MATERIALS AND METHODS. We performed a retrospectivestudy of 84 patients with a Hartmann's pouch who underwent contrast-enhanced radiography of the pouch during a recent 7-year period. Sixty-four patients underwent single-contrast barium studies of the pouch, 17 underwent studies with a water-soluble contrast medium, and three underwent both types of studies. The radiographic studies were reviewed to determine the types and fre quencyof abnormalitiesinvolvingthe pouch.Medical recordswere also reviewedto deter mine clinical presentation andcourse.RESULTS. Abnormalitiesof the Hartmann'spouchwere detectedon contrast-enhanced radiography in 16 (19%) of the 84 patients. Of the 70 patients who underwent routine con trast-enhanced radiography of the pouch, 11 (16%) had abnormalities, including diversion colitis in three,leaks in two, adhesionsin two, recurrentcarcinomain two, ulcerativecolitis involving the pouch in one, and a stricture in one. In both patients with clinically silent leaks, the contrast-enhanced radiography was performed 3 months or more after creation of the pouch. Of the remaining 14 patients who underwent contrast-enhanced radiography because of suspectedcomplications involving the pouch, five (36%) had abnormalities revealed, in cluding leaks in two, fistulas in two, and recurrent carcinoma in one.CONCLUSION. Contrast-enhanced radiographyof the Hartmann'spouchrevealedab normalitiesof thepouchin 19% of patients,includingleaksor fistulas,diversioncolitis,adhe sions, strictures, and recurrent tumor. Because two patients had clinically silent leaks that were detected during the late postoperative period, it may be prudent to perform these studies with a water-soluble contrast medium to avoid the problems associated with extravasation of barium into the extra-or intraperitoneal spaces.T he Hartmann's procedure is a common surgical procedure in which a temporarydiverting co lostomy and blind-ending rectal or colonic stump closed by suture (Hartmann's pouch) are created after partial colectomy or sig moidectomy [1]. This procedureis usually performed on an emergent basis in patients with complicated diverticulitis, obstructing or perforated sigmoid carcinoma, or pene trating trauma [2,3]. When such patients un dergo sigmoid resection, a Hartmann's procedure is performed rather than primary reanastomosis of the bowel because of the risk of anastomotic rupture associated with inadequate bowel preparation, complicating peritonitis,or both.The creationof a tempo rary diverting colostomy allows peritoneal inflammationto subside;the colostomycan then be taken down and reanastomosed to the pouch during the second stage of the proce dure to restore colonic continuity.Leakage or even blowout ofthe blind-end ing rectal or colonic stump can occur as a po tentially life-threatening complication of the Hartmann's procedure [4â€"7].
