Pelvic floor reconstruction after major cancer surgery
BACKGROUND: Many surgical techniques to keep the small intestine out of
the pelvis after cancer surgery have been developed. METHODS: We used
part of the ileum and its mesentery sutured around the linea terminalis
in ten patients who underwent surgery for rectal or gynecologic
carcinomas. RESULTS: All imaging studies of our patients on the tenth
postoperative day confirmed the position of the bowel above the pelvis.
Four of ten patients had radiation treatment postoperatively without any
problems. CONCLUSION: Use of the ileum to reconstruct the pelvic floor
seems to be a simple and efficacious technique to keep the pelvic area
free. We believe this warrants further investigation in a larger number
of patients
Implantation of microballoons in the management of fecal incontinence
PURPOSE: The implantation of expandable microballoons has proved
successful for the treatment of stress urinary incontinence. This led us
to test its effectiveness in the treatment of severe fecal incontinence.
METHODS: Six patients (four male), of average age of 43 (range, 29-60)
years, with severe fecal incontinence, underwent implantation of
expandable microballoons in the submucosa of the anal canal. The
implantation was performed under intravenous sedation as an outpatient
procedure. Anal manometry, endosonography, and incontinence assessment
with a scoring system were performed before and after the implantation.
RESULTS: With a mean follow-up of 8.6 (range, 7-12) months, the
incontinence scores improved in all patients from an average of 16.16
(standard deviation: +/- 1.6) before the implantation to an average of 5
(standard deviation: +/- 1.26) after the procedure, The anal pressure at
rest was not improved in any patient (mean: 50.16 before treatment to a
mean of 53 after treatment). No significant adverse events were
associated with the procedure, and no serious postimplantation
complications were noted. DISCUSSION: Anal implantation of expandable
microballoons seems to be a simple, safe, and effective method that
restores the fecal continence without hindering normal defecation

A pilot assessment of whether external coil MRI is useful to assess evacuatory disorders
This study assessed the value of common surface coil magnetic resonance imaging (MRI) in patients with evacuatory disorders including fecal incontinence and constipation. These findings were then compared with those from other standard physiological examinations and/or surgical findings. From July 1996 to June 1997, 14 consecutive patients underwent surface coil MRI for evaluation of either fecal incontinence (n=5) or constipation (n=9). In patients with incontinence we compared the findings from endoanal ultrasound (EAUS), anal MRI, and surgery regarding morphopathological findings of the internal and external anal sphincter components. In constipated patients the findings of videoprography and dynamic pelvic MRI were compared regarding the presence of rectocele, rectoanal intussusception, and sigmoidocele as well as the measurements of anorectal angle and perineal descent. The five incontinent patients were all women, with a median age of 67 years (range 43-77). EAUS revealed an anterior sphincter defect in two patients, a posterior defect in one, and normal anal sphincter images in two. Surgical findings confirmed an anterior external anal sphincter scar in two patients, an internal anal sphincter defect in one, and an anatomically normal anal sphincter in two. In one patient, although anal MRI showed posterior external anal sphincter defect, EAUS and surgery revealed normal external anal sphincter appearance. The accuracy rate between EAUS and anal MRI was only 20%, that between surgery and anal MRI 40%, and that between surgery and EAUS 80%. Thus EAUS was more accurate than anal MRI in incontinent patients. The nine constipated patients were all women, with a mean age of 59 years (range 40-78). Videoproctography revealed an anterior rectocele in six patients, rectoanal intussusception in three, and sigmoidocele in five; no abnormalities were identified in two patients. On dynamic pelvic MRI anterior rectocele was seen in three patients and sigmoidocele in two, and five studies were interpreted as normal. One of the patients underwent sigmoidectomy for sigmoidocele, and five patients were treated by biofeedback. Thus the accuracy rate of dynamic pelvic MRI against videoproctography was 60% for anterior rectocele, 40% for sigmoidocele, and zero for rectoanal intussusception. In conclusion, neither MRI for the evaluation of patients with fecal incontinence nor for the evaluation of patients with constipation added any significant information that would warrant its continued use in these patient groups. Perhaps the more widespread availability of an endoanal coil will alter this conclusion; however, at the present time we cannot routinely endorse the expense, time, or inconvenience of these MRI investigations in patients with these diagnoses. Larger prospective comparative studies are required prior to endorsing the technique
Total Laparoscopic Approach for Rectal Cancer Resection—a Novel Technique and Review of the Literature
Quantificação da função esfincteriana pela medida da capacidade de sustentação da pressão de contração voluntária do canal anal Sphincteric function quantification by measuring the capacity to sustain the squeeze pressure of the anal canal
RACIONAL: Tem sido demonstrado que a pressão máxima de contração voluntária e a pressão média de repouso não refletem a real situação clínica do paciente portador de incontinência fecal, não traduzem a realidade funcional do canal anal, além de poder estar comprometendo a conduta a ser tomada devido ao não-encaminhamento à terapêutica específica. OBJETIVO: Com a hipótese de que contrair e manter a contração é mais importante que simplesmente contrair, mesmo com pico momentaneamente elevado de pressão, analisou-se a capacidade de sustentação da pressão de contração voluntária do canal anal com o intuito de quantificar a função esfincteriana relativa à continência fecal. MATERIAL E MÉTODOS: Submeteram-se a exame manométrico anorretal 72 pacientes (56 mulheres) portadores de incontinência fecal de vários graus e 15 (9 mulheres) indivíduos continentes (normais), avaliando-se a pressão média de repouso, a pressão máxima de contração voluntária e a capacidade de sustentação da pressão de contração voluntária. RESULTADOS: Os indivíduos continentes apresentaram valores normais de pressão média de repouso e de pressão máxima de contração voluntária, além de adequada capacidade de sustentação da pressão de contração voluntária. Os pacientes incontinentes apresentaram pressão média de repouso e pressão máxima de contração voluntária com valores pressóricos normais ou abaixo do normal e perfil semelhante de capacidade de sustentação da pressão de contração voluntária, ou seja, moderada na fase inicial e ruim nas fases intermediária e final, com queda da mesma superior a 35% em 78% dos pacientes. A pressão máxima de contração voluntária apresenta excelente especificidade (100%) porém, sensibilidade baixa (46%) para incontinência fecal. Comparativamente, a capacidade de sustentação da pressão de contração voluntária apresenta elevadas especificidade (93%) e sensibilidade (78%) para incontinência fecal. Embora a pressão máxima de contração voluntária não indique falso-positivos, apresenta 72% de falso-negativos. A probabilidade deste fato acontecer com a medida de capacidade de sustentação da pressão de contração voluntária é, praticamente, 20% menor, valor estatisticamente significativo. CONCLUSÃO: O indicativo de função esfincteriana é melhor analisado pela capacidade de sustentação. A capacidade de sustentação traduz com mais exatidão, a capacidade funcional do canal anal em relação à continência voluntária, sendo isoladamente, melhor que a pressão máxima de contração voluntária.<br>BACKGROUND: It has been demonstrated that the maximum squeeze pressure and the mean resting pressure do not reflect the true clinical situation of patients having fecal incontinence, as well as the functional status of the anal canal. Furthermore, a wrong diagnosis could be obtained and therefore misleading to a not effective treatment. AIM: Under the hypothesis that squeezing and sustaining the anal canal contraction is more important than the maximum squeeze pressure, the capacity to sustain the squeeze pressure of the anal canal was analyzed aiming to quantify the sphincteric function. METHODS: Seventy-two patients having fecal incontinence in different degrees (56 female) and 15 normal individuals (9 female) were submitted to anorectal manometry to measure the mean resting pressure, the maximum voluntary squeeze pressure and the capacity to sustain the squeeze pressure. RESULTS: Normal individuals had normal values of mean resting pressure and maximum squeeze pressure, and adequate capacity to sustain the squeeze pressure of the canal anal. Incontinent patients had mean resting pressure and maximum squeeze pressure with normal or below normal pressoric values and similar profile of capacity to sustain which was moderate in the initial phase and worse in the intermediate and final phases, with decreasing of the capacity to sustain more than 35% in 78% of the patients. The maximum squeeze pressure presented excellent specificity (100%), but low sensitivity (46%) for fecal incontinence. Comparatively, the squeeze pressure presented high specificity (93%) and high sensitivity (78%) for fecal incontinence. Although the maximum squeeze pressure did not indicate false positive, it presented a 72% false negative. The probability of this event to happen with the capacity to sustain measure is 20% lower, and it was statistically significant. CONCLUSION: Sphincteric function can be better analyzed by using the capacity to sustain the squeeze pressure. capacity to sustain indicates more precisely the functional capacity of the anal canal in relation to voluntary continence, and it is better than maximum squeeze pressure as an isolated index
