The authors outline the stages of abdominoperineal surgery due to rectal cancer to achieve the reconstruction of perineal-stomic continence. The operation is simple to perform, without particular vascular risks and sepsis; it does not necessitate temporary abdominal colostomy and, lastly, does not oblige postoperative stomic functional rehabilitation.

From 1981 to 1994, intra-operative radiotherapy after subtotal cystectomy was performed on 22 patients with invasive bladder carcinoma on whom radical cystectomy could not be recommended because of old age or condition. All the patients received 25 to 30 Gy of radiotherapy focused on trigonum and internal urethral orifice after subtotal cystectomy with uretero-cutaneostomy. Of 22 patients, 15 patients died. Five patients died of bladder cancer, one died of gastric cancer, one died of rectal cancer and the others died of pneumonia, heart failure, sepsis and senility. The five-year survival rate was 41% and the cause-specific five-year survival rate was 75%. Local recurrence was seen only in one patients, who received second intra-operative radiotherapy and recovered well in complete remission. We believe that intra-operative radiotherapy after subtotal cystectomy is useful for patients with invasive bladder carcinoma on whom radical cystectomy could not be recommended because of old age or condition.

Perioperative blood transfusion (PBT) has proved to increase the risk of sepsis after surgery. The hypothesis that PBT also might increase the occurrence of leak of rectal anastomoses has been tested. The data of 94 patients undergone low anterior resection for rectal cancer were reviewed. Thirty-nine of them (41%) received one or more packed red cells (PRC) units perioperatively. The total dehiscence rate was 14% (13 cases), and it was significantly lower in not-transfused (4%) compared to transfused patients (28%) (p < 0.005). The risk of dehiscence was increased by six-fold if up to two, and by fifteen-fold if more than two PRC units were given. These findings suggest that leakage of rectal anastomoses should be considered among the detrimental effects of PBT. The risk of dehiscence increases with the number of units transfused. A judicious administration of blood might contribute to reduce this complication.

Surgical treatment of carcinoma of the distal third of the rectum with anal sphincter preservation is increasingly used in accredited cancer centers. This study aimed to evaluate the diagnostic usefulness of radiological investigations in the management of patients who had undergone resection with coloanal anastomosis for carcinoma of the rectum, in the immediate post-operative period, during closure of the protective colostomy and in the follow-up of symptomatic recanalized patients. A total of 175 patients who had undergone total rectal resection with end-to-side anastomosis for carcinoma of the distal third of the rectal ampulla, most of whom had received postoperative radiotherapy, were evaluated radiologically. In the postoperative period radiological investigation was ordered only for symptomatic patients to detect pathology of the anastomosis and the pouch sutures and was used direct film abdominal radiography and contrast-enhanced radiography of the rectal stump with a water-soluble radio-opaque agent. Before closure of the colostomy, 2 months after rectal excision or approximately 4 months after if postoperative radiotherapy was given, the anastomosis and pouch of all patients, even asymptomatic ones, were studied with water-soluble contrast enema to check for normal canalization. In the follow-up after recanalization radiological examinations were done to complete the study of the large intestine if the endoscopist was not able to examine it up to the cecum. Of the 175 patients examined radiologically during the postoperative period and/or subsequent follow-up, 95 showed no pathological findings. Seventy-nine patients had fistulas of the coloanal anastomosis or the pouch, 23 of which supplied a presacral collection. In the absence of severe sepsis, the only therapeutic measures were systemic antibiotics and washing of the surgical catheters to maintain efficient operation. In 2 patients in whom transanal drainage was performed radiologically the fistula was cured in 1 week. In 36 cases of cicatricial stenosis, 17 at the coloanal anastomosis and 19 at the pouch, radiological examination always detected the lesion, correctly defining its anatomical characterisitics, nature and extension. Of the 19 cases of stenosis treated radiologically, 15 recovered an adequate intestinal calibre for tients operated on, 21 cases of reccurrence were detected. Radiological examination was requested as the first investigation in only one of these cases, for a patient with subocclusion. Radiological investigations in patients who have undergone colonanal anastomosis are of read diagnostic value in the immediate post-operative period, during closure of the protective colostomy and in the follow-up of symptomatic recanalized patients.

Prospective randomized clinical trials have shown the effectiveness of combined adjuvant 5-fluorouracil-based chemotherapy and radiotherapy after surgical resection of rectal cancer. To assess toxicity of this therapy, prospective data were collected from 236 Asian rectal cancer patients treated with combined 5-fluorouracil-based chemotherapy and radiotherapy after surgery. Almost 82% of patients completed planned therapy. Grade 3 and 4 diarrhea, stomatitis, and granulocytopenia occurred in approximately 18-21% of patients. There were two treatment-related deaths from granulocytopenia and sepsis. With median follow-up of 3.5 years, median disease-free and overall survival was 75 and 88 months, respectively. In conclusion, combined adjuvant 5-fluorouracil-based chemotherapy and radiotherapy after surgical resection of rectal cancer is tolerable in Asian patients with moderate toxicity.

Endoanal and endorectal ultrasound have an important role in colorectal surgery. They can be applied in the management of faecal incontinence, rectal tumours and inflammatory perianal conditions. In faecal incontinence, anal ultrasound will confirm the presence or absence of sphincter defects. This will direct any operative intervention such as direct sphincter repair. Ultrasound in rectal cancer allows staging of the tumour by assessing the depth of invasion through the bowel wall and involvement of mesenteric nodes. Such staging might influence the choice of operation and determine which patients might benefit from preoperative chemotherapy and radiotherapy. Ultrasound has a particular role in recurrent and complex anal fistula and perianal sepsis. Preoperative and perioperative planning with accurate delineation of fistula tracts, extensions and sphincter involvement might help prevent recurrence and impaired continence from sphincter damage after surgery. Correct interpretation of ultrasound images requires training and experience so that the results can be properly correlated with the clinical situation.

Accurate staging of rectal and anal carcinoma is crucial for planning surgery and indicating adjuvant therapy. Although, computed tomography and magnetic resonance imaging are very sensitive in detecting metastatic disease, the local staging of rectal cancer with these techniques has been disappointing. Endorectal ultrasound (ERUS) and anal endosonography (AE) remain the most accurate methods for staging rectal and anal cancer. Anal endosonography is also of value in evaluating perianal sepsis: it can assist the surgeon in planning the surgical strategy by delineating the anatomy of fistula tracts, and can aid in puncturing abscesses in the operating room. Continued research and development has made the instrumentation for ERUS and AE more accurate and user-friendly. New techniques that have contributed significantly to the evolution of ERUS include three-dimensional ERUS, high-frequency miniprobes, transrectal ultrasound-guided biopsy techniques and hydrogen peroxide-enhanced endosonography. Further improvements can be expected from contrast enhancement with microbubbles and colour Doppler imaging. In this new millennium, new developments in ERUS and anal endosonography, such as tri-dimensional ERUS and anal endosonography and radial electronic probing, widen the role of ERUS in the staging of rectal and anal carcinoma, as well as for perianal inflammatory conditions.

A case of a 64 years old female patient who had had a Miles operation 6 years ago for rectal cancer and at the present hospital admission she came in with a severe infection around her left colostomy. Initially, she presented a quite localized peristomal infection but, subsequently, the infection has evolved to an extensive necrotizing fasciitis of the abdomen, a large dehiscence of colostomy and severe sepsis. Repeated surgery and transverse colostomy, to put at rest infected left colostomy, plus aggressive medical treatment resulted in a good recovery, with the wounds healing and redo of the left colostomy. Now she is on the waiting list to get rid of the transverse colostomy.

Anorectal diseases require imaging for proper case management. At present, endoanal ultrasonography and endorectal ultrasonography have become important parts of diagnostic workup of patients with fecal incontinence, perianal fistulas, and rectal cancer and provides sufficient information for clinical decision-making in many cases. However, with the currently available ultrasonographic equipment and techniques, a good deal of relevant information may remain hidden. The advent of high-resolution three-dimensional endoluminal ultrasound, constructed from a synthesis of standard two-dimensional cross-sectional images, and of "Volume Render Mode," a technique to analyze information inside a three-dimensional volume by digitally enhancing individual voxels, promises to revolutionize diagnosis of pelvic floor disorders. By use of the different postprocessing display parameters, the volume-rendered image provides better visualization performance when there are not large differences in the signal levels of pathologic structures compared with surrounding tissues. The anatomic structures in the pelvis, the axial and longitudinal extension of anal sphincter defects, the anatomy of the fistulous tract in complex perianal sepsis, and the presence of slight or massive submucosal invasion in early rectal cancer may be imaged in greater detail. This additional information will bring an improvement for both planning and conduct of surgical procedures.

A 75-year-old previously healthy man presented for elective resection of rectal cancer under general anesthesia. Six days before the operation, he had a high-grade fever, and elevated leukocyte count and C-reactive protein concentration, but this was resolved by an intravenous antibiotic. His condition was well controlled before the operation. Soon after the operation started, severe hypoxemia emerged, with low arterial pressure. Fiberoptic bronchoscopy demonstrated a massive amount of plasma-like edema fluid; the total amount of suctioned fluid was approximately 800 ml at the end of the surgery. This acute pulmonary edema appeared to be due to increased permeability rather than pulmonary congestion as indicated by chest radiography, pulmonary artery occlusion pressure, echocardiogram, and the protein-rich edema fluid. Elevated concentrations of the proinflammatory cytokines, interleukin (IL)-6 and IL-8, in both plasma and the pulmonary edema fluid, suggested a possible role of systemic and pulmonary inflammation in the development of this acute pulmonary capillary leak. According to the "two-hit" hypothesis, the bacterial infection preceding the operation may have primed the immune cells, and the following surgical stress may have then triggered rapid progression of acute respiratory distress syndrome. We should keep in mind that, especially following sepsis, sudden massive pulmonary capillary leak can occur during elective surgery, even though the patient's condition is well controlled.
