A critical appraisal of pathogenesis and morbidity of surgical treatment of chronic anal fissure
No full textPreoperative and postoperative manometric findings and the results of lateral internal sphincterotomy were analyzed in 44 consecutive patients affected with chronic anal fissure. Preoperatively, resting anal pressure was increased in 32 patients. At one month postoperatively, 23 patients showed normal pressures, whereas 14 were still hypertonic and seven, hypotonic. Only three patients still had a weak sphincter six months postoperatively. The overall morbidity rate was 31.8 percent. Minor complications occurred in 11 patients. Major complications affected three patients. Overall, impaired continence was recorded in eight patients, although only two complained of persistent, albeit lesser, defects of continence not requiring the use of pads. Nonoperative treatment should be reserved for few selected patients with recent, acute fissures. As for chronic and fissures, compared with other operative or nonoperative modalities of treatment, lateral internal sphincterotomy is a highly successful procedure and its minimal morbidity is well accepted by the patient

Impact of Computed Tomography versus intrarectal ultrasound on the diagnosis, resectability, and Prognosis of locally recurrent Rectal Cancer.
No full textThe use of modern techniques of imaging in the postoperative follow-up is reported to allow an earlier diagnosis of local recurrence in patients operated on with anterior resection for rectal cancer and, consequently, to allow a higher percentage of local recurrence resection to be performed. Although intrarectal ultrasound (IU) has proved highly reliable in preoperative staging, its value in relapse detection has been investigated only in retrospective studies and rarely compared with that of computed tomography (CT). The present prospective study aims at evaluating the role of IU vs. CT in the diagnosis of local recurrence and at verifying whether an earlier diagnosis and a higher resectability rate of recurrence result in an acceptable long-term survival. Thirty-seven patients who had undergone low and ultralow anterior resection for rectal cancer (anastomosis within 10 cm of the anal verge) were investigated prospectively. All the patients have been followed up by IU and CT at predetermined intervals. Six local recurrences were detected. CT correctly identified all the local recurrences (sensitivity = 100 percent, specificity = 93 percent, and accuracy = 94.5 percent); IU correctly identified only four of six local recurrences (sensitivity = 66.6 percent, specificity = 93 percent, and accuracy = 89 percent). Four patients with local recurrence underwent surgical treatment (resectability rate = 66.6 percent). Abdominoperineal resection in three patients and Hartmann's procedure in one patient were performed. In the other two patients, extensive metastatic liver involvements contraindicated surgery. All the resected patients were alive after one year; two of them are disease free, and the other two experienced recurrent disease. In conclusion, CT seems to have a higher sensitivity and accuracy in relapse detection. The increase in the local recurrence resectability rate does not result in a significant improvement in long-term survival. However, the good quality of life justifies the high cost of an intensive follow-up and a more aggressive surgical approach
