Abstract
Patients may present with anal incontinence (AI) following repair of a congenital anorectal anomaly years previously, or require total anorectal reconstruction (TAR) following radical rectal extirpation, most commonly for rectal cancer. Others may require removal of their colostomy following sphincter excision for Fournier's gangrene, or in cases of severe perineal trauma. Most of the data pertaining to antegrade continence enema (the ACE or Malone procedure) comes from the pediatric literature in the management of children with AI, but also with supervening chronic constipation, where the quality of life and compliance with this technique appears superior to retrograde colonic washouts. Total anorectal reconstruction requires an anatomical or physical supplement to the performance of a perineal colostomy, which may include an extrinsic muscle interposition (which may or may not be 'dynamized'), construction of a neorectal reservoir, implantation of an incremental artificial bowel sphincter or creation of a terminal, smooth-muscle neosphincter. The advantages and disadvantages of these techniques and their outcome are presented here.

Abstract
AIM This study aimed to assess long-term function after total perineal reconstruction (TPR) with dynamic graciloplasty (DG) and systematic Malone appendicostomy (MA) adjunction after abdominoperineal excision (APR) for rectal cancer. METHOD From 1999 to 2004, TPR using DG and MA was performed in 10 patients [seven women; median age 40 (range 28-55) years] after APR for rectal cancer (cT2 in one patient, cT3 in six patients and cT4 in three patients). We prospectively recorded early and late morbidity, mortality, oncological outcome, functional results (using the modified Working Party on Anal Sphincter Replacement 'WPASR' scoring system) and quality of life (QoL; using the European Organisation for Research and Treatment of Cancer 'EORTC' QLQ-C30 and QLQ-CR38 questionnaires). RESULTS There was no procedure-related mortality. One patient required intra-abdominal re-operation. Nine patients required local and multiple revisions [there was one coloperineal anastomosis (CPA) stenosis, five CPA mucosal prolapse, three stenosis related to graciloplasty, two MA stenosis and one MA reflux]. After a median follow up of 78 months, there was no local recurrence and six patients were alive and disease-free. Regarding the functional results, the median modified WPASR score, of 8, after a follow up of 78 months, was good. The overall QoL scores remained stable over time. CONCLUSION In carefully selected patients who want to avoid definitive abdominal colostomy after APR for rectal cancer, reconstruction involving MA and DG after APR for low rectal cancer is followed by good long-term function and QoL.

Abstract
AIMS To report the outcomes of anorectal reconstruction by electrostimulated graciloplasty as part of abdominoperineal resection, on data prospectively collected over 10 years. PATIENTS AND METHODS Twenty-three abdominoperineal resections were associated to coloperineal pull through, double graciloplasty and loop abdominal stoma. Fifteen patients also received an implantable pulse generator, either for unsatisfactory result after external-source intermittent electrostimulation and biofeedback (five cases) or during graciloplasty (10 cases). Follow-up was to a maximum of 10 years. Functional outcome was followed up in sixteen patients who underwent stoma takedown. RESULTS Mean actuarial survival at 5 years was 72.3%. Satisfactory results (score < or =8) occurred in 75% of patients (three without and 13 with stimulator) in the early stages, decreasing to 57% at 1 year and gradually increasing up to 100% at 5 years and over. CONCLUSIONS Total anorectal reconstruction yields a good functional outcome over time. Thus, despite, and because of, a high complication rate and a great drain on resources, it should be considered a suitable procedure only for selected, strongly motivated patients.

Abstract
AIM This prospective study was designed to evaluate functional results of a pseudocontinent perineal colostomy (PCPC) using Schmidt's technique. METHODS Functional results in eight patients whose rectum were resected due to cancer or anal epidermoid carcinoma and reconstructed by PCPC between January 1995 and July 2002 in our institution were evaluated. Surgical technique and post-operative care were described. Morbidity, functional results and degree of patient satisfaction were reported. Median follow-up was 40 months (18-70 months) and was completed in 100% of patients. RESULTS There were no operative deaths. Four patients had post-operative complications, whose two patients had partial disunion of sutures, and two patients had urinary infection that was treated by adequate antibiotherapy. No conversion to a definitive abdominal colostomy was performed. On a functional level, one patient has normal continence, six had gas incontinence, and one has occasional minimal soiling. Seventy-five percent of patients were either highly satisfied with their continence. DISCUSSION PCPC is a reliable technique, which can be proposed as an alternative to a left iliac colostomy following amputation of the rectum due to cancer, provided that certain requirements are met: careful selection of patients, informed consent, flawless surgical technique and lifetime daily colic irrigation.

Abstract
BACKGROUND AND AIMS Surgical and functional results after abdominoperineal resection and total anorectal reconstruction by electrostimulated gracilis muscle transposition are still poorly documented. This study prospectively evaluated surgical and functional outcome over time in our patients. PATIENTS AND METHODS Twenty-three patients underwent abdominoperineal resection, coloperineal pullthrough, double graciloplasty, and loop abdominal stoma. Temporary external-source intermittent electrostimulation, biofeedback training, and selective delayed stimulator implantation to improve unsatisfactory results were carried out in the first 13 patients (1st series); thereafter (2nd series) the stimulator was implanted during graciloplasty. Surgical and oncological results were followed up in all patients. Functional results were evaluated in 16 patients who underwent abdominal stoma takedown, eight in each of the two series, by anomanometry (up to 1 year) and our own 0-20 scoring system (up to 8 years from initial surgery). RESULTS The rate of major and minor postoperative complications was 21.7% and 65%, respectively. Continuous electrostimulation proved effective on resting anal pressure. Early clinical assessments showed satisfactory functional results (considered as having a score < or =8) in all first-group patients, including five who had stimulator support, and in one-half of second-group patients. After impairment (at least 2 points) at 1 year in five patients, four of whom were from the first group, all functional results improved and became satisfactory from 5 years on (1st series) and from 4 years on (2nd series). CONCLUSION Despite marked morbidity the high rate of good results, which improved over time, suggests that total anorectal reconstruction is worth being performed as part of abdominoperineal resection in well-selected patients with a strong motivation to avoid a permanent colostomy.

Abstract
Presently, deep rectal carcinoma is usually treated by deep anterior rectal resection and colonal anastomosis. Abdominoperineal resection is needed only for the very few patients whose tumors infiltrate the pelvic base or sphincter musculature. This means the loss of normal anal function and thus of normal defecation. Many patients find the idea of a stoma unacceptable. In our experience, the construction of a functional neoanus after abdominoperineal rectal resection is a suitable option for patients in good general health and who are highly motivated.

Abstract
PURPOSE Until recently, patients who underwent abdominoperineal resections had to cope with a colostomy for the rest of their lives. For some of these patients this colostomy was a terrible burden, physically and mentally. Publications about abdominoperineal pull-through and double dynamic graciloplasty immediately after a Miles resection showed good results. The purpose of this study was to investigate the procedure as a secondary approach after abdominoperineal resections. METHODS In this study seven patients were evaluated. All had had an abdominoperineal resection and proved to have unbearable problems with their stoma. All had a secondary pull-through and double dynamic graciloplasty, a mean of 8.5 (range, 1.1-34.8) years after the Miles resection. RESULTS In five patients continence was regained; two were reversed to colostomy because of several complications. Patients who had a successful outcome also suffered from numerous complications, with a total mean hospital stay of 73.8 (range, 27-167) days, a mean of 3.1 (range, 1-6) additional operations, and 1.8 (range, 0-4) readmissions. CONCLUSION Secondary anorectal reconstruction after abdominoperineal resection is a feasible option, but with a high morbidity. Because of this the procedure was stopped at the beginning of 1997.

Abstract
PURPOSE Chronic low-frequency electrical stimulation can safely transform fatiguing muscle into fatigue-resistant muscle. This fundamental discovery was used to reconstruct the anal sphincter. Dynamic graciloplasty was found to be effective in the treatment of fecal incontinence. Our study was undertaken to investigate the oncologic, functional, and quality of life results of dynamic graciloplasty anal reconstruction after an abdominoperineal resection for carcinoma. METHODS Between April 1993 and April 1996, nine patients (4 males) with a median age of 51.2 (range, 29-69) years underwent an abdominoperineal resection for carcinoma (4 had a rectal adenocarcinoma and 5 had an epidermoidal anal tumor) and an anal sphincter reconstruction with electrically stimulated graciloplasty. Oncologic and functional results were evaluated after a mean follow-up of 32 (range, 14-50) months. A quality of life questionnaire was filled out by seven patients. RESULTS Sphincter reconstruction required the same hospitalization period as abdominoperineal resection. Two patients died from evolutive disease. Three patients were operated on twice, one for immediate colonic necrosis, two for colonic perforation after enema. One of them refused the graciloplasty and had an abdominoperineal resection. Six patients were dysfunctioned. The mean resting pressure was 24 +/- 10 mmHg, and the mean pressure during stimulation was 95 +/- 25 mmHg. Five patients were continent for solids and liquid; four wore less than three pads per day, and one wore more than three. Four patients used enemas twice a week; one patient had spontaneous evacuation. The quality of life questionnaire showed that the mean scores for social interaction, symptoms, and psychological and physical states were 2.1, 2.2, 2.4, and 2.7, respectively. The mean value was 1.5. CONCLUSIONS Total anorectal reconstruction with dynamic graciloplasty is an oncologically safe procedure. Functional results improve with time, but careful patient selection guarantees a successful functional outcome. Technical progress is necessary to improve the quality of life.

Abstract
PURPOSE The aims of the study contained herein were to analyze the efficacy and safety of a chronically electrostimulated double-wrap graciloplasty for restoration of continence after a curative abdominoperineal resection for rectal carcinoma and to evaluate late results of a stimulation protocol that was begun early. METHODS During the last six years, 31 consecutive patients underwent this procedure: in 24 patients, electrostimulated double-wrap graciloplasty was performed simultaneously with abdominoperineal resection for lower rectal cancer, 7 strictly selected patients underwent conversion to an abdominal stoma following previous abdominoperineal resection (mean length of time from stoma creation, 71.4 months) Anorectal reconstruction was performed following a surgical scheme already standarized since 1985 in 102 patients: after abdominoperineal resection, the distal colon was pulled through to the perineum and surrounded by both gracilis muscles following an "alfa and new-sling" configuration; using platinumiridium electrodes, both muscles were then connected to pulse generator, which was implanted subcutaneously in the abdomen. All surgical steps were performed during the same surgical session to allow early postoperative stimulation of the transposed muscles. A contemporary covering stoma was abandoned as a standard procedure; the distal colon was left closed for a few postoperative days, then it was resected and sutured to the perineum under local anesthesia. Eighteen patients underwent preoperative or postoperative radiotherapy or both, without any significant adverse outcome. To increase gracilis resistance to prolonged "tonic" contraction, patients underwent a chronic, low-frequency stimulation protocol. In the last 11 patients, a new "over-the-nerve and intramuscular" implant was adopted to optimize fiber recruitment and to reduce electrostimulation thresholds. At regular intervals, all patients were evaluated using continence scores and questionnaires, electromanometry, endoluminal ultrasound study, and defecography. RESULTS Twenty-six of 31 patients were evaluated for continence, with a mean length of follow-up of 37.8 (range, 4-68) months; 3 patients died because of cancer recurrence, 1 underwent conversion to an abdominal stoma, and 1 is waiting for stoma closure. Continence to liquid and solid stools was achieved in 22 patients (85 percent), and electromanometry findings confirmed a good muscular contraction postoperatively and during follow-up intervals. No postoperative mortality (40 days) was observed; the postoperative complication rate was high 22-percent), but early treatment (drainage and temporary diversion in 7 patients) led to favorable outcomes (4 resolutions, 3 partial muscular impairments). Four stimulators had to be temporarily explanted because of late complications, and two stimulators had to be replaced because of battery exhaustion after three years of use with high stimulation parameters. A significant difference was observed comparing full-contracting threshold after intramuscular (14 patients) and the new over-the-nerve and intramuscular implant technique. CONCLUSIONS The study contained herein confirms the efficacy of the surgical scheme we have adopted since 1985 to reconstruct sphincteric apparatus after abdominoperineal resection of the rectum. The "one-step" timing of surgical and electrostimulation-related procedures and the early start of stimulation did not show a significant increase in the complication rate and did not produce noticeable muscular or nerve damage. Adoption of chronic electrostimulation protocols using implantable devices increased the rate of fully continent patients; nevertheless, the overall cost for devices and medical staff duties was high, and a small increase of late morbidity was observed. Finally, the preliminary experience with our new technique of electrode implants encourages further application.

Abstract
PURPOSE To review and to update the results of Total Anorectal Reconstruction with Electrostimulated Graciloplasty (ES-TAR) at the same time as or following abdominoperineal resection (APR). SETTING A university hospital in Italy. METHODS Retrospective study. POPULATION A series of 98 consecutive anorectal cancer patients who had undergone ES-TAR (in 88 cases at the same time as APR; in 10 cases following APR), 61 of whom are still evaluable in respect of continence (median follow-up period 55 months). RESULTS There was no mortality. Thirty-seven percent of patients had postoperative complications with no impact on survival or functional outcome. The 5-year survival rate in 50 patients was 61% and the 5-year estimated cumulative probability of survival in 81 patients was 65%. Local recurrence rate was 16%. Continence was achieved in 87% of patients with a chronically stimulated TAR, and in 69% of patients with short-term stimulation. CONCLUSION ES-TAR is a safe and effective method for both curing anorectal cancer and restoring continence. It may be considered a reliable alternative to sphincter-saving procedures in lower rectal cancer patients.

Abstract
PURPOSE Total anorectal reconstruction with a double dynamic graciloplasty was performed after abdominoperineal reconstruction (APR) for low rectal cancer. In four patients an additional pouch was constructed to improve neorectal motility and capacity. The aim of this study was to evaluate the results in the first 20 patients and to report on the preliminary results of patients with an additional pouch. METHODS Twenty patients with a mean age of 52 (range, 25-71) years and a rectal tumor at a mean of 3 (range, 0-5) cm from the anal verge were treated. In 14 patients the Miles resection, colon pull-through, and construction of a neosphincter were performed in one session. Six patients had the double graciloplasty at an average of 4.1 (range, 1.1-8.8) years after APR. In four patients a pouch was constructed with an isolated segment of distal ileum. RESULTS After a mean follow-up of 24 (range, 1-60) months after APR, none of the patients developed local recurrence, whereas four patients developed distant metastasis. Fifteen of 20 patients were available for evaluation, and 5 patients were still in training. Of these 15 patients, 8 patients were continent (53 percent), 2 patients were incontinent, and in 5 patients the perineal stoma was converted to an abdominal stoma. Failures were attributable to necrosis of the colon stump (n = 2) and incontinence (n = 3). At 26 weeks mean resting pressure was 44 (standard deviation (SD), 28) mmHg, and mean pressure during stimulation was 90 (SD, 46) mmHg at a mean of 3.5 (SD, 1.2) volts at 52 weeks. Mean defecation frequency was three times per day (range, 1-5). Of the eight patients who were continent, six used daily enemas. Mean time to postpone defecation was 11 (range, 0-30) minutes. CONCLUSION In experienced hands, the double dynamic graciloplasty is an oncologically safe procedure that can have an acceptable functional outcome in a well-selected group of patients. However, to improve the outcome, further modifications will be necessary. So far, the addition of a pouch has not resulted in improved outcome.

Abstract
OBJECTIVE The authors investigated the feasibility and effectiveness of combining electrically stimulated gracilis neoanal (ESGN) sphincter and a coloperineal anastomosis in selected patients after abdominoperineal excision of the rectum (APER). SUMMARY BACKGROUND DATA The ESGN is effective in the treatment of idiopathic fecal incontinence. METHODS Between March 1989 and September 1993, 12 patients (9 men, 3 women) with a median age of 59.25 years (range, 45-70) underwent the procedure. The underlying disease was adenocarcinoma in 10, anal malignant melanoma in 1, and a sweat gland tumor in the other. In all patients, a sphincter saving resection was contraindicated. The procedure was performed in stages. Stage 1 involved a conventional APER with the formation of a perineal stoma. Eleven patients underwent a vascular delay procedure. All patients were defunctioned. In stage 2, the gracilis was mobilized, transposed around the anal canal, and the electrodes and hardware needed for electrical stimulation were implanted. Once muscle conversion was complete, the defunctioning stoma was closed. RESULTS Eight patients were closed successfully. In seven of the eight patients, complete physiologic measurements were taken. Median basal and maximum neosphincter pressures were 30 and 122 cm H2O, respectively, at the start of electrical stimulation and 22.5 and 76.2 cm H2O, respectively, after 1 year. Median functioning neosphincter pressure was 36 cm H2O at 1 year. All of the patients whose stomas were closed experienced episodes of incontinence to solid stool and wore pads for persistent fecal soiling. They all reported difficulty in evacuation. Despite imperfect continence, no patient wished to go back to life with a stoma. CONCLUSIONS The incorporation of ESGN as part of total anorectal reconstruction is technically feasible. The majority of patients are satisfied with their function and pleased to avoid a permanent stoma.

Abstract
PURPOSE To review the complications, survival, and long-term functional outcome of patients with anorectal cancer who had restorative perineal graciloplasty (RPG) simultaneously with abdominoperineal resection (APR). METHODS Between 1985 and 1994, 81 patients underwent APR plus RPG. Gracilis muscles were then conditioned by electrostimulation, either intermittently or chronically. Thirtyseven surviving patients were followed for a mean of 78.6 months and were analyzed for long-term functional outcome of RPG. RESULTS Postoperative complications occurred in 30 patients (37 percent). Crude five-year survival rate was 58 percent, and five-year estimated cumulative probability of survival was 65 percent. There was no statistically significant difference for probability of survival and for probability of disease-free interval between uncomplicated and complicated patients. Fecal continence was obtained in 90 percent of patients. CONCLUSION RPG does not reduce the effectiveness of APR in the cure of cancer. Postoperative complications, though frequent, were not serious and resolved without sequelae. There was no statistically significant impact on the probability of survival and of disease-free interval by graciloplasty. Continence was achieved by most patients (90 percent) who underwent RPG simultaneously with APR.
