[Transanal endoscopic microsurgery for local excision of rectal neoplasms].

We removed 30 benign, sessile, rectal polyps by the transanal approach between January 1990 and April 1994. In 16 patients we used transanal endoscopic microsurgery (TEM), while in 14 the adenoma was removed by submucosal excision (SE). There were 3 local recurrences in the SE group, but none as yet in the TEM group. There was no operative mortality. Early complications included myocardial infarction in 1 patient and persistent postoperative fever which responded to antibiotic treatment in another. Late complications included temporary, anal mucous leakage in 10% and 5% of the TEM and SE groups, respectively. TEM was found to be efficient for the removal of polyps in the upper and middle thirds of the rectum, and SE for those in the lower third. This enables safe removal of rectal polyps, avoiding the need for complex operations involving greater risks.

[Anal incontinence in patients with rectal neoplasms previous to surgical intervention].

HYPOTHESIS: Patients with rectal carcinoma may have anal continence disorders before the operation, in relation to age. AIM: To evaluate the anorectal function in a consecutive sample of patients with rectal carcinoma before the operation. MATERIAL AND METHODS: 56 consecutive patients with rectal carcinoma were studied and classified into two groups according to anal continence: continent and incontinent. Anorectal function were evaluated in all patients: Perineometry (perineal measurements at rest and during a straining effort), Anal manometry (anal pressures and rectal capacity), Pudendal nerve terminal motor latency. STATISTICAL ANALYSIS: quantitative data: -test (confidence interval), qualitative data: Fischer exact test. RESULTS: Anal continence: continent 41, incontinent 15. All patients with anal incontinence were more than 60 years old (p<0.01). Mean age: continent 61.3 +/- 12.4, incontinent 74.3 +/- 6 (p<0.01, CI 8.02-17.98). Perineal measurement: at rest: continent 2.97 +/- 0.69. incontinent 2.54 +/- 0.56 (p<0.05, CI 0.03-0.83), with straining effort: continent 1.37 +/- 0.86, incontinent 0.81 +/- 0.92 (p < 0.05, CI 0.03 - 1.86). Pudendal latency: continent 1.9 +/- 0.3, incontinent 2.3 +/- 0.5 (p<0.01, CI 0.11-0.69). There was no significant difference in the manometric data. CONCLUSION: Patients with rectal carcinoma have preoperative anal continence alterations, in relation to pelvic disorders and age.

[Value of preoperative colonoscopy in colon-rectal neoplasms].

The surgical approach to treat colo-rectal carcinoma is usually based on the findings of barium enema. In 102 patients we reviewed the yield of pre-operative colonoscopy. Barium enema revealed the cancer in 76 of 84 patients (91%), whereas colonoscopy did so in 96 of 102 subjects (94%). In addition, 5 associated cancerous lesions were demonstrated by colonoscopy and none by barium enema. Associated benign lesions were seen in 14 patients. In 5 patients the surgical plan based on the barium enema was modified by the findings at colonoscopy. Eight false negatives to barium enema were correctly diagnosed by colonoscopy. We conclude that colonoscopy yields valuable information, beyond that of barium enema, in patients with colo-rectal cancer.

[Opaque enema and radiography of defecation in the pre- and postoperative morpho-functional evaluation of rectal neoplasms].

From November 1989 to April 1990, 16 patients with rectal cancer were examined preoperatively by means of double contrast barium enema and defecography. Double contrast barium enema was used to identify the cancer: based on the distance of cancer from anal rima, the patients were divided into 3 groups: 1) less than 6 cm; 2) 6-11 cm; 3) more than 11 cm. In all patients defecography was performed at the end of barium enema to evaluate rectal wall mobility. Thus, the morphological information yielded by barium enema could be integrated with the dynamic data from defecography. The evaluation was thus possible of both longitudinal and, indirectly, transverse tumor spread. All the patients underwent surgery and radiological findings were compared with surgical ones. In those patients in whom defecography had shown rigidity of the rectal walls, extraparietal tumor spread was observed during surgical resection. Seven patients underwent anterior resection, and were subsequently examined by the same combination of barium enema and defecography. The combined use of the two methods was useful to evaluate the anastomosis and to show possible dynamic changes after surgery.

[Rectal neoplasms: the current state of surgical treatment].

The number of patients with rectal cancer ist increasing steadily in the BRD. Even if diagnosis of early stages of rectal cancer is not too difficult, the fatal diagnostic delay is 7-8 months on the average. After operative methods have been subtilized and radicalized only preventive medical examinations and early public instruction may improve the prognosis of the patients concerned. Additional treatment with cytostatical agents seems to be promising. If preventive medical care makes it possible to detect rectal cancer in its early stages, the same operative results can be obtained by the meanwhile developed continence-preserving methods as by the hitherto carried out widespread and continence-sacrificing rectal resection as our own experiences prove.
