Abstract
Fecal incontinence has an enormous social and economic impact and may significantly impair quality of life. Even though fecal incontinence is a common complaint in (aging) adults, a structured pathophysiological model of the clinical presentations of fecal incontinence is missing in current literature. The most frequent manifestations of fecal incontinence are passive fecal loss, urge incontinence, or mixed fecal incontinence. At our institution, we treat 400 patients per year with defecation disorders, including a significant number of patients with fecal incontinence. On the basis of this experience, we have tried to create a concept that merges current insight in causes and treatment options in a clinically useful algorithm. By applying the system of anamnesis and physical examination described in this article and expanding it with simple additional anorectal examination, in most patients, one can determine the type of fecal incontinence and choose a targeted therapy.

Guedj N, Zappa M, Maggiori L, Bertin C, Hennequin C, Panis Y. Is it time to rethink the rule of total mesorectal excision? A prospective radiological and pathological study in 49 consecutive patients with mid-rectal cancer. Colorectal Dis 2016; 18:O314-21. [PMID: 27381492 DOI: 10.1111/codi.13449] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2015] [Accepted: 04/07/2016] [Indexed: 02/08/2023]
Abstract
AIM Total mesorectal excision (TME) after neoadjuvant chemoradiotherapy is the standard treatment for T3-T4 and/or N+ mid-rectal tumours, regardless of the exact tumour level. This leads to optimal oncological results but possible impaired functional results. Reducing rectal excision could reduce the functional drawbacks. This study prospectively assessed the risk of N+ or other mesorectal tumour deposit (OTD) below the tumour level by magnetic resonance imaging (MRI) performed after chemoradiotherapy and pathological examination of the TME specimen. METHOD Consecutive patients with mid-rectal cancer who underwent TME after chemoradiotherapy were included. A prospective evaluation by postchemoradiotherapy MRI and pathological examination was performed to assess the location of N+ nodes and/or OTDs. RESULTS Of 49 consecutive patients, 27 (55%) presented with nodes on postchemoradiotherapy MRI. However, only 12 nodes (size 2-4 mm) in 9 patients (18%) were under the tumour level. On pathological examination, 717 total lymph nodes were found, with 37 N+ and 22 OTD. According to the tumour level: (i) above tumour level, 21/453 nodes were N+ and 6 OTD; (ii) at tumour level, 16/166 nodes were N+ and 15 OTD; (iii) below tumour level, 0/98 nodes (0%) was N+ and only 1 OTD (2%) was noted at 2 cm below tumour level. CONCLUSION After chemoradiotherapy, N+ and/or OTD located under the level of the rectal cancer seems to be a very rare event. A postchemoradiotherapy MRI could help detect such patients. For others patients, conservation of the lower rectum with only a subtotal mesorectal excision could possibly improve function.

Reduced luminal circumference of tumors plays a key role in anorectal function during the early period after neoadjuvant chemoradiation therapy in rectal cancer patients. Int J Colorectal Dis 2015; 30:465-74. [PMID: 25712808 DOI: 10.1007/s00384-015-2155-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 02/02/2015] [Indexed: 02/04/2023]
Abstract
PURPOSE The deterioration of anorectal function after neoadjuvant chemoradiation therapy (nCRT) combined with surgery for rectal cancer has not been well defined. The aim of this study was to evaluate the relationship between the tumor response to nCRT and changes in anorectal function during a short-term period after nCRT. METHODS We analyzed 100 consecutive patients with available preoperative anorectal manometry data, both before and after nCRT, from 2010 to 2013. RESULTS Comparing the manometric data before and after nCRT, the values reflecting rectal sensory function after nCRT was significantly lower than those before nCRT. However, in patients who experienced changed tumor morphology and a reduction in luminal circumferential ratio (LCIR) of tumor after nCRT, the values reflecting rectal sensory function were significantly less decreased after nCRT. On multivariate analysis, the reduction of LCIR after nCRT was a very important factor preventing the impairment of anorectal function during the short-term period in terms of the first rectal sensory threshold (RST) (P = 0.002), the RST of "desire to defecate" (P = 0.006), and rectal compliance (P = 0.003). Additionally, in linear regression analysis, the RST for the desire to defecate was positively affected by tumor morphology (P = 0.015) and the reduced LCIR (P = 0.025), and rectal compliance was positively affected by the reduced LCIR (P = 0.001). CONCLUSION The nCRT impaired significantly rectal sensory function during the short-term period after nCRT and before a radical operation. However, this reduced LCIR of tumors after nCRT may prevent or minimize impediments to anorectal function during the short-term period after nCRT.

Abstract
INTRODUCTION The aim of this study was to investigate the clinical outcomes between 2 groups of elderly rectal cancer patients according to the time duration after which their diverting stoma can be reversed. METHODS We recruited 124 patients who were ≥65 years old and had undergone diverting stoma after rectal cancer surgery. In Group 1, the reversal of the stoma was predominantly performed after the sixth adjuvant chemotherapy. In Group 2, the reversal was predominantly performed after the third adjuvant chemotherapy. RESULTS The mean duration for which patients had a stoma was 28.6 ± 9.9 weeks in Group 1 and 17.1 ± 7.4 weeks in Group 2. The interval between stoma formation and stoma formation-related complications was slightly longer in Group 1 than in Group 2 (13.5 ± 9.7 vs. 8.0 ± 4.9 weeks, p = 0.075). There were 16 stoma-related complications in Group 1 (23.2%) and 10 in Group 2 (18.2%) (p = 0.516). There were 6 stoma closure-related complications in Group 1 (8.8%) and 6 in Group 2 (10.9%) (p = 0.766). DISCUSSION This study shows that stoma closure during adjuvant chemotherapy is no more harmful than stoma closure after termination of adjuvant chemotherapy. CONCLUSION It may be possible to limit the duration of diverting stoma following rectal cancer surgery, even if patients are elderly and undergoing adjuvant chemotherapy.

Abstract
BACKGROUND Rectal cancer patients' expectations of health and function may affect their disease- and treatment-related experience, but how patients form expectations of postsurgery function has received little study. OBJECTIVE We used a qualitative approach to explore patient expectations of outcomes related to bowel function after sphincter-preserving surgery for rectal cancer. DESIGN This was a cohort study of patients who were about to undergo sphincter-preserving surgery for rectal cancer. SETTINGS The study was conducted through individual telephone interviews with participants. PATIENTS Twenty-six patients (14 men and 12 women) with clinical TNM stage I to III disease were enrolled. MAIN OUTCOME MEASURES The semistructured interview script contained open-ended questions on patient expectations of postoperative bowel function and its perceived impact on daily function and life. Two researchers analyzed the interview transcripts for emergent themes using a grounded theory approach. RESULTS Participant expectations of bowel function reflected 3 major themes: 1) information sources, 2) personal attitudes, and 3) expected outcomes. The expected outcomes theme contained references to specific symptoms and participants' descriptions of the certainty, importance, and imminence of expected outcomes. Despite multiple information sources and attempts at maintaining a positive personal attitude, participants expressed much uncertainty about their long-term bowel function. They were more focused on what they considered more important and imminent concerns about being cancer free and getting through surgery. LIMITATIONS This study was limited by context in terms of the timing of interviews (relative to the treatment course). The transferability to other contexts requires further study. CONCLUSIONS Patient expectations of long-term functional outcomes cannot be considered outside of the overall context of the cancer experience and the relative importance and imminence of cancer- and treatment-related events. Recognizing the complexities of the expectation formation process offers opportunities to develop strategies to enhance patient education and appropriately manage expectations, attend to immediate and long-term concerns, and support patients through the treatment and recovery process.

Abstract
OBJECTIVE. There is no consensus regarding reconstruction type after anterior resection for rectal cancer. We conducted a meta-analysis of relevant randomized controlled trials (RCTs) to compare outcomes of colonic J-pouch (CJlP) and side-to-end anastomosis (STEA) after anterior resection of rectal cancer. METHODS. Electronic databases were searched in January 2013, with six RCTs selected for further analysis, for a total of 451 patients (229 CJP, 222STEA). Outcome measures included surgical, physiologic, and functional outcomes, as well as postoperative complications. The odds ratio (OR) was used in the statistical analysis; in other circumstances, qualitative descriptions were performed. RESULTS. As far as surgical outcomes and postoperative complications, there was no difference between groups. While functional outcomes were substantially impaired, this was similar between groups. CJP demonstrated better function in the early postoperative period. No difference was seen between groups with regards to physiologic outcome. CONCLUSION. CJP and STEA are comparable when choosing the type of reconstruction for restoration of bowel continuity in anterior resection for rectal cancer.

Abstract
Background Neoadjuvant chemoradiation therapy followed by curative surgery has gained acceptance as the therapy of choice in locally advanced rectal cancer. However, deterioration of anorectal function after long-course neoadjuvant chemoradiation therapy combined with surgery for rectal cancer is poorly defined. The aim of this study was to evaluate the physiological and clinical change of anorectal function after neoadjuvant chemoradiation therapy for rectal cancer. Methods We analyzed 30 patients on whom preoperative anorectal manometry data were available both before and after chemoradiation from October 2010 to September 2011. All patients underwent long-course neoadjuvant chemoradiation therapy. We compared manometric parameters between before and after neoadjuvant chemoradiation therapy. Results Of 30 patients, 20 were males and 10 females. The mean age was 64.9 ± 9.9 years (range, 48-82). Before nCRT, the rectal compliance was higher in patients with ulceroinfiltrative type (P = 0.035) and greater involvement of luminal circumference (P = 0.017). However, there was the tendency of increased rectal sensory threshold for desire to defecate when the patient had decreased circumferential ratio of the tumor (P = 0.099), down-graded T stage (P = 0.016), or reduced tumor volume (P = 0.063) after neoadjuvant chemoradiation. Conclusions Neoadjuvant chemoradiation therapy did not significantly impair overall sphincter function before radical operation. The relationship between tumor response of chemoradiation and sensory threshold for desire to defecate may suggest that neoadjuvant chemoradiation may be helpful for defecatory function as well as local disease control, at least in the short-term period after the radiation in locally advanced rectal cancer patients.

Abstract
PURPOSE The use of barium enemas to confirm the anastomotic integrity prior to ileostomy closure is still controversial. The purpose of the study was to determine the utility of routine contrast enema prior to ileostomy closure and its impact on patient management in patients with a low pelvic anastomosis. METHODS One hundred forty-five patients had a temporary loop ileostomy constructed to protect a low colorectal or coloanal anastomosis following low anterior resection for rectal cancer. All patients were evaluated by physical examination, proctoscopy, and barium enema prior to ileostomy closure. RESULTS The median time from ileostomy creation to closure was 8 months. Five (3.5%) of the 144 patients were found to have clinically relevant strictures at the colorectal anastomosis on routine barium enema. One patient (0.7%) showed anastomotic leak on their barium enema. Overall, 141 patients (97.9%) had an uncomplicated postoperative course. Postoperative complication occurred in three patients (2.1%). None of them showed abnormal barium enema finding, which suggested that routine contrast enema examination did not predict postoperative complication. CONCLUSION Routine barium enema evaluation of low pelvic anastomoses before loop ileostomy closure did not provide any additional information for postoperative colorectal anastomotic complication.

Abstract
AIM Transanal irrigation (TAI) has been reported to be a cheap and effective treatment for the 'anterior resection syndrome (ARS)'. This study aimed to evaluate its effect on the quality of life (QOL) of patients suffering from ARS. METHOD In a prospective study involving two colorectal centres, 14 patients (11 male; median age 68 (45-80) years) were included in the study. The median duration of ARS was 19 (9-48) months. The median number of defaecations was 8 (4-12)/day and 3 (2-5)/night. All patients were trained to perform TAI using the Peristeen™ System under the guidance of a stoma nurse. Anal physiology was performed, quality of life (QOL) was estimated by the SF-36 and Rockwood (ASCRS) questionnaires and continence by the Cleveland Incontinence Score. RESULTS At the last follow up the median time of using TAI was 29 (15-46) months. The median volume of water used for the irrigation was 900 (500-1500) ml. There was a significant decrease in the number of defaecations during the day (baseline, 8 [4-12]; last follow up, 1 [1-2]) and at night (baseline, 3 [2-5]; last follow up, 0 [0-0]). The Cleveland Incontinence Score fell from 17 [15-20] (baseline) to 5 [4-9] (last follow up) and the mental component of the SF-36 and all domains of the Rockwood QOL instrument improved. CONCLUSION Transanal irrigation is an effective treatment of anterior resection syndrome and results in a marked improvement of the continence score and QOL.

Abstract
The introduction of total mesorectal excision (TME) for rectal cancer has reduced local recurrence rates and improved oncologic outcomes, although complication rates such as anastomotic leak have also been a consequence. With the advent of neoadjuvant therapy for rectal cancer, many are questioning how this development may change the role of TME. This review presents a history of how TME evolved and a description of this technique. Complication rates, the impact of neoadjuvant therapy on local recurrence, variations of TME such as nerve-sparing proctectomy and cancer-specific mesorectal excision, and a review of functional outcomes for various methods of reconstruction are presented.

Abstract
There are approximately 40,000 new rectal cancer cases diagnosed each year in the United States, representing the second most common gastrointestinal malignancy (behind colon cancer). With the advent of sphincter preserving techniques, patients with mid and low colorectal cancers enjoy the benefits of better postoperative functional outcomes and quality of life; however, controversy exists over which reconstructive technique is superior in restoring bowel continuity. Construction of a straight coloanal anastomosis is technically simpler, but functional outcomes are inferior compared with colonic reservoirs. The purpose of this review is to summarize the current data regarding reconstructive techniques following proctectomy.

Abstract
PURPOSE The purpose of this study was to evaluate the short-term preoperative effects of neoadjuvant chemoradiation on anorectal function, excluding the bias of postoperative impairment. METHODS We analyzed 80 patients on whom preoperative anorectal manometry data were available for both prechemoradiation and postchemoradiation. Patients were divided into 2 groups according to the tumor location; lower rectum (n = 52) and mid rectum (n = 28). The paired t test was used to compare prechemoradiation and postchemoradiation parameters including the mean resting pressure, maximum squeeze pressure, percentage asymmetry of the resting and squeeze sphincter, length of the high-pressure zone, rectal sensory threshold, and rectal compliance. RESULTS In patients with a lower rectal cancer, there were significant differences in the percentage asymmetry of the squeeze sphincter (27.81 +/- 6.46 vs 25.38 +/- 5.93%, P < .01), length of the high-pressure zone (2.14 +/- 0.74 vs 2.33 +/- 0.72 cm, P = .05), and rectal compliance (1.14 +/- 0.41 vs 1.02 +/- 0.40 mL/mmHg, P = .04). In patients with midrectal cancer, only the mean resting pressure increased significantly (45.08 +/- 18.57 vs 52.83 +/- 17.87 mmHg, P < .01). Clinical symptom evaluation demonstrated a significant decrease in the number of defecations and the frequency of tenesmus. CONCLUSION Neoadjuvant chemoradiation did not impair overall short-term sphincter function significantly, regardless of the location of the primary tumor. Although there was a decrease in rectal compliance, it seemed that the tumor-downsizing effect compensated the expected worsening of anorectal function in the early postchemoradiation period.

Abstract
Many retrospective studies have found that the functional outcome after a low anterior resection for rectal cancer is better with colonic J-pouch reconstruction than with conventional straight anastomosis. This advantage was demonstrated in prospective, randomized trials and meta-analyses. However, despite its increasing popularity there are several areas of controversy about the use of the colonic J-pouch reconstruction. These issues include anastomotic leaks, the part of the colon used for the pouch, the pouch size, causes of difficulty in evacuation, indications (the optimum level of anastomosis), appropriateness for the elderly, and long-term (2 years or more after surgery) functional outcome. All relevant articles identified from MEDLINE databases were reviewed. The incidence of anastomotic leaks is apparently reduced by colonic J-pouch reconstruction. A 5-cm colonic J-pouch using the sigmoid colon increases the reservoir function without compromising evacuation, and provides better functional outcome than straight anastomosis, even 2 years or more after surgery, in patients whose anastomosis is less than 8 cm from the anal verge. Patients with ultralow anastomoses, less than 4 cm from the verge, appear to benefit the most. At a time when the indications for abdominoperineal excision appear to be reduced for low rectal cancer, the demand for colonic J-pouch reconstruction (the best technique in pouch operations) is therefore likely to increase.

Abstract
BACKGROUND AND AIMS This study aims to evaluate the therapeutic effect of retrograde colonic irrigation in patients with faecal incontinence after a low anterior resection for a rectal carcinoma. MATERIALS AND METHODS Patients with a previous low anterior resection, who were selected for treatment with retrograde colonic irrigation for faecal incontinence between 2005 and 2008, were included in the study. The data from the patients were gathered by chart research and an interview by phone. RESULTS Thirty patients were included in the study. Three patients died and one patient was not able to answer questions due to a cognitive disorder. The data of the remaining 26 patients were analysed. Five patients had already stopped with the retrograde colonic irrigation treatment due to side effects. Twelve of the 21 patients (57.46%) who still performed RCI became completely (pseudo)continent, three patients (14.2%) were incontinent for flatus and six patients (29.4%) were still incontinent for liquid stool. Five patients stopped with the retrograde colonic irrigation treatment due to side-effects. CONCLUSION Retrograde colonic irrigation is an effective method to treat patients with faecal incontinence after a low anterior resection for rectal carcinoma. Retrograde colonic irrigation is not invasive and has only mild side effects.

Abstract
Surgery is the cornerstone of rectal cancer treatment. Oncological cure and overall survival continue to be the main goals, but sparing of the anal sphincter mechanism and functional results are also important. The modern management of rectal cancer is a multidisciplinary approach, and pre-operative staging is of crucial importance when planning treatment in these patients. Pre-operative staging is used to determine the indication for neoadjuvant therapy prior to surgical resection or to determine whether local excision is an option in carefully selected patients with early rectal cancer. Surgery in the form of total mesorectal excision (TME) has become the standard of care for mid and distal rectal cancers. Early rectal cancers do not require neoadjuvant therapy. For locally advanced cancers of the lower two-thirds of the rectum, the combination of surgical resection with chemoradiotherapy decreases local recurrence rates and probably improves overall survival. Whereas in the past local excision was only contemplated in patients who were unfit for radical surgery or for local palliation in cases of metastatic disease, over the last number of years there has been increasing interest in local treatment with curative intent in early rectal cancer.

Abstract
AIM: To evaluate the quality of life and local recurrence for rectal cancer which under vent posterior pelvic exenteration (PPE) with anal sphincter preservation.
METHODS: Sixty cases with rectal cancer invading female reproductive system underwent PPE with anal sphincter preservation (SP group) or colon stoma (CS group) respectively. Thirty cases with low anterior resection rectal cancer were selected as control group (LAR group).Wexner scoring systems and vectorial manometry were used to compare the quality of life between the SP group and LAR group, and compare the 2-year local recurrence rate and survival rate between the SP group and CS group.
RESULTS: Three months after surgery, the Wexner score of SP group was higher than that of the LAR group (10.1 vs 6.1, P < 0.05), but there were no significant difference in score 1 year after surgery between two groups (P > 0.05), and the results of vectorial manometry between two groups also showed no significant difference (P > 0.05). The local recurrence rate and survival rate were 20% and 83.3% for SP group, 23.3% and 80% for CS group with no significant difference observed (both P > 0.05).
CONCLUSION: The quality of life after posterior pelvic exenteration with anal sphincter preservation could reach the level of low anterior resection, and the local recurrence rate and survival rate were similar with colon stoma operation.

Abstract
The aim of this study was to describe bowel problems, self-care practices, and information needs of patients who have recovered from the acute effects of sphincter-saving surgery for colorectal cancer. A retrospective, descriptive survey was conducted using a structured telephone interview and mailed questionnaires. The sample consisted of 101 patients who had undergone sphincter-saving surgery for colorectal cancer in the last 6 to 24 months. Most participants (71.3%) reported a change in bowel habits after surgery. The 6 most frequently reported gastrointestinal problems were incomplete evacuation (75.2%), excessive flatus (75.2%), urgency (73.3%), straining (61.4%), perianal soreness or itching (49.5%), and bloating (43.6%). Incontinence of feces (varying from smears to complete bowel action) was reported by 37.6% of participants. The most frequently reported information needs were related to diet (50.5%) and managing conditions such as diarrhea (31.7%), bloating/wind/gas (28.7%), pain (21.8%), and incomplete emptying of the bowel (18.8%). Patients who had recovered from the acute effects of sphincter-saving surgery for colorectal cancer reported a wide range of bowel problems and ongoing concerns about managing symptoms. Findings from this study provide valuable information to guide the development of educational resources to prevent or better manage bowel problems after surgery.

Abstract
OBJECTIVE Colonic pouch formation with pouch-anal anastomosis is the treatment of choice following restorative anterior resection for low rectal cancers with a proximal loop ileostomy to defunction the anastomosis. Controversy exists as to whether anastomotic integrity needs to be checked prior to ileostomy reversal. The aim of this prospective study was to audit our current practice. METHOD Data on all patients undergoing resectional surgery for rectal cancer in our unit are entered prospectively onto a database. Patients who underwent an anterior resection with pouch formation and defunctioning ileostomy were identified and a review of notes and radiological records was carried out. RESULTS Forty-two patients with rectal adenocarcinoma underwent an anterior resection with colo-colonic pouch, colo-anal anastomosis and a covering loop ileostomy. Of these, 38(90.5%) had water-soluble contrast enemas (WSCE) 6-8 weeks postoperatively. Two studies (5.3%) confirmed the presence of normal colo-colonic pouch but 24(63.2%) normal reports made no mention of the presence of pouch. Three studies (7.9%) reported true leaks, one study (2.6%) an anastomotic stricture and eight studies (21.1%) anastomotic leaks. Review by radiologists and surgeons, and examination with flexible sigmoidoscopy of these final eight confirmed that these appearances were consistent with normal colo-colonic pouches and anastomosis with no leak. These patients went on to have uneventful stoma closure. CONCLUSION Our study suggests that Colon pouches are difficult to clearly delineate on WSCE and appearances may be mistaken for leaks leading to questioning of the suitability of WSCE in assessing anastomotic integrity. A true positive leak rate of 7.9% would suggest that postoperative assessment prior to closure is still necessary in some patients.

Abstract
BACKGROUND Total mesorectal resection (TME) has led to improved survival and reduced local recurrence in patients with rectal cancer. Straight coloanal anastomosis after TME can lead to problems with frequent bowel movements, fecal urgency and incontinence. The colonic J pouch, side-to-end anastomosis and transverse coloplasty have been developed as alternative surgical strategies in order to improve bowel function. OBJECTIVES The purpose of this study is to determine which rectal reconstructive technique results in the best postoperative bowel function. SEARCH STRATEGY A systematic search of the literature (MEDLINE, Cancerlit, Embase and Cochrane Databases) was conducted from inception to Feb 14, 2006 by two independent investigators. SELECTION CRITERIA Randomized controlled trials in which patients with rectal cancer undergoing low rectal resection and coloanal anastomosis were randomized to at least two different anastomotic techniques. Furthermore, a measure of postoperative bowel function was necessary for inclusion. DATA COLLECTION AND ANALYSIS Studies identified for potential inclusion were independently assessed for eligibility by at least two reviewers. Data from included trials was collected using a standardized data collection form. Data was collated and qualitatively summarized for bowel function outcomes and meta-analysis statistical techniques were used to pool data on postoperative complications. MAIN RESULTS Of 2609 relevant studies, 16 randomized controlled trials (RCTs) met our inclusion criteria. Nine RCTs (n=473) compared straight coloanal anastomosis (SCA) to the colonic J pouch (CJP). Up to 18 months postoperatively, the CJP was superior to SCA in most studies in bowel frequency, urgency, fecal incontinence and use of antidiarrheal medication. There were too few patients with long-term bowel function outcomes to determine if this advantage continued after 18 months postop. Four RCTs (n=215) compared the side-to-end anastomosis (STE) to the CJP. These studies showed no difference in bowel function outcomes between these two techniques. Similarly, three RCTs (n=158) compared transverse coloplasty (TC) to CJP. Similarly, there were no differences in bowel function outcomes in these small studies. Overall, there were no significant differences in postoperative complications with any of the anastomotic strategies. AUTHORS' CONCLUSIONS In several randomized controlled trials, the CJP has been shown to be superior to the SCA in bowel function outcomes in patients with rectal cancer for at least 18 months after gastrointestinal continuity is re-established. The TC and STE anastomoses have been shown to have similar bowel function outcomes when compared to the CJP in small randomized controlled trials; further study is necessary to determine the role of these alternative coloanal anastomotic strategies.

Abstract
BACKGROUND AND AIMS Because of their low morbidity and mortality, limited resection or local excision are accepted therapeutical approaches in early colorectal cancer treatment. Even though, recent publications report recurrence rates after local excision of rectal cancer in up to 30%. This prompted us to evaluate our data for T1N0 colorectal cancer treated by radical surgery regarding recurrence, morbidity, mortality, and survival rates. MATERIALS AND METHODS Clinical, histopathological, and surveillance data from our prospective "colorectal cancer database" from 1979 to 2005 were analyzed to evaluate outcome and prognosis of T1N0 colorectal cancer treated by radical surgery. Only curative resections were included in this study. All patients were followed in an internal surveillance program, which enabled us to prospectively assess morbidity, mortality, and survival. RESULTS A total of 105 T1N0 colon and 69 rectal carcinomas were included in the study. Overall morbidity was 25% (colon) and 34% (rectum). Thirty-day mortality was 1.9% (colon) and 4.3% (rectum). After a median follow-up of 92 and 87 month, no isolated local recurrence occurred. One patient developed both local recurrence and liver metastases. Distant metastases were seen in 4.9% (colon) and 7.5% (rectum). The 5- and 10-year overall survival was 86 and 71% (colon) and 82 and 68% (rectum), respectively. CONCLUSION Even if radical surgical approaches are associated with a higher rate of morbidity and mortality, our data show that radical surgery for T1N0 colorectal cancer results in excellent tumor control which is of paramount importance for the patients' prognosis and survival. Combining the data presented with those of the current literature suggests that local approaches to rectal cancer can be recommended for highly selected T1N0 tumors, in palliative situations, or if the patient is unfit for general surgery.

Abstract
Treatment of rectal cancer over the last two decades has evolved with changes in techniques of surgery and radiation based on national and international trials. Preoperative adjuvant radiation is now preferred over postoperative adjuvant radiation, and total mesorectal excision with preservation of pelvic nerves is the gold standard for surgical treatment of rectal cancer. Preservation of the anal sphincter without compromising oncological outcome is an additional benefit for patients with carcinoma in the distal rectum. Further progress in imaging and a multidisciplinary team approach will facilitate individualization of treatment strategy with more focus on quality of life.

Abstract
BACKGROUND Anal incontinence is experienced by some patients with rectal cancer who received low anterior resection. This study was to examine the efficacy and adverse effects of the alpha-1 adrenergic agonist phenylephrine, which causes contraction of the internal anal sphincter and raises the resting pressure in these patients. PATIENTS AND METHODS Thirty-five patients with anal incontinence were treated with 30% phenylephrine or a placebo randomly allocated in a double-blind study. The efficacy of the drug was assessed by changes in the following standardized questionnaire scores: the fecal incontinence severity index (FISI), fecal incontinence quality of life (FIQL) scales, and a global efficacy question. Anal sphincter function was evaluated using anorectal manometry. RESULTS Phenylephrine did not improve either the FISI score or any of the four FIQL scores. Five of 17 (29%) patients reported subjective improvement after phenylephrine compared with 4 of 12 (33%) using the placebo. The maximum resting anal pressure did not differ between baseline and after 4 weeks application of phenylephrine (30.0 to 27.3 mmHg). In the phenylephrine group, allergic dermatitis was developed in five patients and headache in two. CONCLUSION In the patients with anal incontinence after low anterior resection for rectal cancer, phenylephrine gel did not seem to be helpful in relieving symptoms with some adverse effects.

Abstract
PURPOSE Both motor and sensory dysfunction have been implicated in the pathogenesis of obstructed defecation. We have found that despite preservation of a defecatory urge, patients with obstructed defecation have lost the normal predefecatory augmentation in frequency and amplitude of colonic propagating pressure waves. This observation might be explainable by either altered rectal sensory thresholds or by dysfunction in the colonic motor apparatus. By measuring rectal sensory thresholds and proximal colonic motor responses to rectal mechanical and chemical stimuli, we tested the hypotheses that central perception of rectal stimuli is enhanced and that the proximal colonic motor response to rectal stimulation is attenuated. METHODS In seven patients with obstructed defecation and ten healthy volunteers we measured proximal colonic motor responses and sensory thresholds in response to both rectal balloon distention and rectal instillation of chenodeoxycholic acid. RESULTS In controls, but not in patients, rectal mechanical distention significantly reduced and chemical stimulation significantly increased the frequency of proximal colonic propagating sequences (P = 0.01). There was no significant difference in rectal sensory thresholds between patients and controls. Prior instillation of chenodeoxycholic acid significantly reduced (P < 0.03) maximum tolerated balloon volume and defecatory urge volume to comparable degree in both patients and controls. CONCLUSIONS In obstructed defecation, 1) the normal rectocolonic pathways mediating stimulation-induced proximal colonic propagating pressure waves are nonfunctioning, and. 2) central perception of these rectal stimuli is normal.

Abstract
PURPOSE The purpose of this national study was to examine the long-term results of transanal excision compared with major surgery of T1 rectal cancer. METHODS This prospective study from the Norwegian Rectal Cancer Project included all 291 patients with a T1M0 tumor within 15 cm from the anal verge treated by anterior resection, abdominoperineal resection, Hartmann's procedure, or transanal excision in the period from November 1993 to December 1999. RESULTS Two hundred fifty-six patients were treated by major surgery and 35 patients by transanal excision. None of the patients had neoadjuvant therapy. Macroscopic tumor remnants (R2) occurred in 17 percent (6/35) of the transanal excisions, while major surgery obtained 100 percent R0 resections. Eleven percent of the patients treated with major surgery had glandular involvement. There were no significant differences according to tumor localization, size, or differentiation between Stage I and Stage III tumors. Patients treated with transanal excision were older than patients having major surgery (mean age, 77 vs. 68 years, P < 0.001). After curative resection (R0, R1, Rx) the five-year rate of local recurrence was 12 percent (95 percent confidence interval, 0-24) in the transanal excision group compared with 6 percent (95 percent confidence interval, 2-10) after major surgery (P = 0.010). The overall five-year survival was 70 percent (95 percent confidence interval, 52-88) in the transanal excision group compared with 80 percent (95 percent confidence interval, 74-85) in the major surgery group (P = 0.04) and the five-year disease-free survival was 64 percent (95 percent confidence interval, 46-82) in the transanal excision group compared with 77 percent (95 percent confidence interval, 71-83) in the major surgery group (P = 0.01). CONCLUSIONS The main problem of transanal excision for early rectal cancer in the present study was the inability to remove all the malignancy. Patients treated with transanal excision had significantly higher rates of local recurrence compared with patients who underwent major surgery. Patients who had transanal excision had inferior survival, but they were older than those who had major surgery.

Abstract
PURPOSE Sphincter-preserving surgery is technically feasible for many rectal cancers, but functional results are not well understood. Therefore, the purpose of this study was to develop an instrument to evaluate bowel function after sphincter-preserving surgery. METHODS A 41-item bowel function survey was developed from a literature review, expert opinions, and 59 patient interviews. An additional 184 patients who underwent sphincter-preserving surgery between 1997 and 2001 were asked to complete the survey and quality-of-life instruments (Fecal Incontinence Quality of Life, European Organization for Research and Treatment of Cancer QLQ 30/Colorectal Cancer 38). A factor analysis of variance was performed. Test-retest reliability was evaluated, with 20 patients completing two surveys within a mean of 11 days. Validity testing was done with clinical variables (gender, age, radiation, length of time from surgery), surgical variables (procedure: local excision, low anterior resection, coloanal anastomosis), reconstruction (J-pouch, straight), anastomosis (handsewn, stapled), and quality-of-life instruments. RESULTS The survey response rate was 70.1 percent (129/184). Among the 127 patients with usable data, 67 percent were male, the median age was 64 (range, 38-87) years, and the mean time for restoration of bowel continuity after sphincter-preserving surgery was 22.9 months. Patients had a median of 3.5 stools/day (range, 0-30), and 37 percent were dissatisfied with their bowel function. Patients experienced a median of 22 symptoms (range, 7-32), with 27 percent reported as severe, 37 percent as moderate, and 36 percent as mild. The five most common symptoms were incomplete evacuation (96.8 percent), clustering (94.4 percent), food affecting frequency (93.2 percent), unformed stool (92.8 percent), and gas incontinence (91.8 percent). The factor analysis identified 14 items that collapsed into three subscales: FREQUENCY (alpha = 0.75), DIETARY (alpha = 0.78), and SOILAGE (alpha = 0.79), with acceptable test-retest reliability for the three subscales and total score (0.62-0.87). The instrument detected differences between patients with preoperative radiation (n = 67) vs. postoperative radiation (n = 15) vs. no radiation (n = 45) (P = 0.02); local excision (n = 10) vs. low anterior resection (n = 55) vs. coloanal anastomosis (n = 62) (P = 0.002); and handsewn (n = 18) vs. stapled anastomosis (n = 99) (P = 0.006). The total score correlated with 4 of 4 Fecal Incontinence Quality of Life (P < 0.01) and 9 of 17 European Organization for Research and Treatment of Cancer subscales (all P < 0.01). CONCLUSIONS Patients undergoing sphincter-preserving surgery for rectal cancer have impaired bowel function, and those treated with radiation, coloanal anastomoses, or handsewn anastomoses have significantly worse function. This reliable and valid instrument should be used to prospectively evaluate bowel function after sphincter-preserving surgery in patients undergoing rectal cancer therapy.

Abstract
AIM: There is some evidence of functional superiority of colonic J-pouch over straight coloanal anastomosis (CAA) in ultralow anterior resection (ULAR) or intersphincteric resection. On the assumption that colonic J-pouch anal anastomosis is superior to straight CAA in ULAR with upper sphincter excision (USE: excision of the upper part of the internal sphincter) for low-lying rectal cancer, we compare functional outcome of colonic J-pouch vs the straight CAA.
METHODS: Fifty patients of one hundred and thirty-three rectal cancer patients in whom lower margin of the tumors were located between 3 and 5 cm from the anal verge received ULAR including USE from September 1998 to January 2002. Patients were randomized for reconstruction using either a straight (n = 26) or a colonic J-pouch anastomosis (n = 24) with a temporary diverting-loop ileostomy. All patients were followed-up prospectively by a standardized questionnaire [Fecal Inco-ntinence Severity Index (FISI) scores and Fecal Incontinence Quality of Life (FIQL) scales].
RESULTS: We found that, compared to straight anastomosis patients, the frequency of defecation was significantly lower in J-pouch anastomosis patients for 10 mo after ileostomy takedown. The FISI scores and FIQL scales were significantly better in J-pouch patients than in straight patients at both 3 and 12 mo after ileostomy takedown. Furthermore, we found that FISI scores highly correlated with FIQL scales.
CONCLUSION: This study indicates that colonic J-pouch anal anastomosis decreases the severity of fecal incontinence and improves the quality of life for 10 mo after ileostomy takedown in patients undergoing ULAR with USE for low-lying rectal cancer.

AIM To report the clinical and oncological data of patients operated on for rectal cancers 3-5 cm from the AV over a 10 year period, including the Sphincter preservation (SP) rate. METHODS We reviewed medical records of 304 patients with rectal cancers 3-5 cm from the AV who underwent surgical resection from January 1991 through December 2000. The 10 years were divided into three periods based on the introduction of new surgical techniques, specifically, ultralow anterior resection (ULAR) with double stapling in March 1994 and ULAR with coloanal anastomosis in April 1997. The rates of SP, complications and patient survival during these periods were compared. RESULTS The SP rate increased significantly over the 10 years, from 16.4% in period I (January 1991-February 1994), to 53.0% in period II (March 1994-March 1997), to 86.5% in period III (April 1997-December 2000) (p<0.001). Over time, the age of the patients increased (p=0.004), the length of the distal resection margin became shorter (p=0.005), and the rate of lymph node metastasis increased (p=0.016). The factors significantly influencing SP were the period (p<0.001) and the distance from the AV (p<0.001). Over time, morbidity did not increase, and overall and disease free survival rates did not decrease. In contrast, the overall survival of N2 cases significantly increased over time (p=0.0492). CONCLUSION Over 10 years, the SP rate in rectal cancers 3-5 cm from the AV was significantly increased by the introduction of the double stapling and coloanal anastomosis techniques. These surgical methods, however, had no effect on morbidity, disease free survival and overall survival rates.

Abstract
Anterior resection of the rectum is a frequent surgical procedure. However, abnormal bowel habits following this procedure are frequently reported. The functional evaluation of these patients is usually limited to the anorectal area. By means of colonic manometry, we have evaluated a patient with frequent urge for defecation and increased bowel frequency following anterior resection of the rectum with straight coloanal anastomosis and almost normal anorectal function. Analysis of the tracing revealed a reduction of contractile segmental activity and much more high-amplitude propagated contractions than which occur in healthy subjects. These high-amplitude propagated contractions, representing the manometric equivalent of mass movements, were always in association with urge for defecation and, sometimes, with loose stools. High-amplitude simultaneous contractions were also observed. We feel that the surgical resection of a potential physiological brake may be responsible for these observations.

Abstract
Our aim was to review the results of total mesorectal excision (TME) in a specialised colorectal unit. Perioperative and follow-up data were prospectively collected in a computerised database. A review of all the records was made. The morbidity rate was about 14%, and was higher in patients with coloplasty due to a higher anastomotic leak rate. The local recurrence rate was 2%, the distant metastasis rate was 11%, and both local and distant metastasis occurred in 4%. About 95% of recurrence occurred within 3 years. There was better bowel function in patients with a colonic J-pouch in the first 2 years after surgery, but the advantage disappeared thereafter. There were no differences in function between descending and sigmoid colonic J-pouches. TME in a specialised colorectal unit has low morbidity and mortality. Our procedure of choice is that of a sigmoid colon J-pouch anal anastomosis.

Abstract
Multiple colonic polyps, almost guaranteed colorectal cancer by the age of forty-five and an increased risk of non-colonic cancers characterise the autosomal dominant condition Familial Adenomatous Polyposis (FAP) [1]. The patients and families faced with such a diagnosis present many difficult management challenges, both surgical and non-surgical. We discuss the current surgical options for treatment of the more significant manifestations of FAP arising in the colorectum and duodenum as well as desmoid disease

Abstract
PURPOSE To date, there is a consensus to consider colonic J-pouch-anal anastomosis as the standard form of reconstruction after proctectomy for cancer. However, one drawback of colonic J-pouch is evacuation difficulties, which are observed at some degree in almost one-half of patients. To improve functional outcome after coloanal anastomosis, we describe a new technique of isoperistaltic colonic H-pouch. METHODS The functional results after construction of this pouch were assessed prospectively in ten patients and compared with those obtained in a control group of matched patients with a colonic J-pouch. RESULTS At six months and one year, there were no differences between both pouches for bowel function, continence score, and evacuation difficulties. CONCLUSIONS This preliminary study showed that the creation of a new isoperistaltic colonic H-pouch did not improve the functional results after coloanal anastomosis compared with colonic J-pouch. Because colonic H-pouch is technically more complex to fashion, it should not be performed routinely and the J-pouch remains the benchmark for routine clinical practice.

Abstract
BACKGROUND Colonic pouch formation with pouch-anal anastomosis is now regarded as the procedure of choice for restoration of intestinal continuity following anterior resection for low rectal cancers. The aim of this study was to review the necessity for routine colonic pouchography prior to closure of a diverting loop stoma. METHODS This was a prospective study of 52 consecutive patients who underwent colonic pouch formation between 1 June 1999 and 31 May 2002, four of whom have subsequently died. Each pouch was assessed clinically and radiologically prior to stoma closure. RESULTS There were no clinical anastomotic leaks. Forty-six of 48 surviving patients have had a colonic pouchogram and in no case was either a pouch or pouch-anal anastomotic defect identified. To date 40 patients have undergone stoma closure without an anastomosis-related complication. CONCLUSION Following successful colonic pouch formation, routine study of the pouch by contrast radiology does not add to clinical assessment. As a consequence radiological imaging is unnecessary and can be omitted.

Abstract
BACKGROUND The National Colorectal Cancer Care Survey was undertaken to determine the management patterns for individuals newly diagnosed with colorectal cancer in Australia. METHODS Between 1 February and 30 April 2000, all new cases of colorectal cancer registered at each Cancer Registry within Australia were entered into the survey. This generated a questionnaire that was sent to the treating surgeons. Chi-squared and logistic regression analyses were used to determine levels of statistical significance for the various comparisons of interest. RESULTS Of 2383 surgical questionnaires generated, 2015 (85%) were completed. A total of 1911 patients (95% of those who responded to the questionnaire) had an operation. Of the 86 guidelines for the management of colorectal cancer published by the National Health and Medical Research Council, the survey allowed for comparison between 18 of these, which covered a spectrum of surgical management. Thromboembolic prophylaxis was given to 1843 patients (96.4%) undergoing surgery. Prophylactic antibiotics were commonly used, but there appear to be issues regarding the best regimen to use. Curative resections were carried out in 1563 patients (81.8%), with anterior resections being the most commonly performed procedure. Adjuvant therapy was regularly used, but not all eligible patients were offered such treatment. CONCLUSION With the considerable resources required to develop clinical practice guidelines, studies like this are essential to monitor the impact of the guidelines. To ensure that the guidelines are in line with current evidence, regular reviews of the guideline recommendations are required.

Abstract
OBJECTIVE To determine the contribution of total mesorectal excision (TME), short-course pre-operative radiotherapy (SCRT), the level of the anastomosis and other putative contributory factors to the incidence and degree of faecal incontinence after anterior resection of the rectum. PATIENTS AND METHODS Survivors of anterior resection of the rectum performed between February 1996 and February 2001, with a functioning anastomosis, were asked to complete a telephone questionnaire regarding their current bowel habit. Faecal incontinence was scored using the St. Mark's Incontinence Score. RESULTS The median age of 124 patients who completed the questionnaire was 76 years. Of these, 104 patients had neoplastic disease, 66 (53%) patients exhibited some degree of incontinence, median St. Marks' Score 6, interquartile range 3-10. There was a significant association between the anastomotic level, and the St. Mark's Score (P < 0.0001, linear regression). Male sex (P = 0.047), SCRT (P = 0.0014) and an anastomotic leak (P = 0.038) were associated with significantly higher incontinence scores. Age, splenic flexure mobilization, TME, anastomotic configuration or use of a temporary stoma had no detectable independent effect on incontinence scores. CONCLUSIONS Poor functional outcome following anterior resection was associated with a low anastomosis, SCRT or an anastomotic leak. The finding that SCRT was a predictor of postoperative incontinence emphasizes the need for stringent patient selection for this treatment modality.

Abstract
OBJECTIVES To compare a colonic J-pouch or a side-to-end anastomosis after low-anterior resection for rectal cancer with regard to functional and surgical outcome. SUMMARY BACKGROUND DATA A complication after restorative rectal surgery with a straight anastomosis is low-anterior resection syndrome with a postoperatively deteriorated anorectal function. The colonic J-reservoir is sometimes used with the purpose of reducing these symptoms. An alternative method is to use a simple side-to-end anastomosis. METHODS One-hundred patients with rectal cancer undergoing total mesorectal excision and colo-anal anastomosis were randomized to receive either a colonic pouch or a side-to-end anastomosis using the descending colon. Surgical results and complications were recorded. Patients were followed with a functional evaluation at 6 and 12 months postoperatively. RESULTS Fifty patients were randomized to each group. Patient characteristics in both groups were very similar regarding age, gender, tumor level, and Dukes' stages. A large proportion of the patients received short-term preoperative radiotherapy (78%). There was no significant difference in surgical outcome between the 2 techniques with respect to anastomotic height (4 cm), perioperative blood loss (500 ml), hospital stay (11 days), postoperative complications, reoperations or pelvic sepsis rates. Comparing functional results in the 2 study groups, only the ability to evacuate the bowel in <15 minutes at 6 months reached a significant difference in favor of the pouch procedure. CONCLUSIONS The data from this study show that either a colonic J-pouch or a side-to-end anastomosis performed on the descending colon in low-anterior resection with total mesorectal excision are methods that can be used with similar expected functional and surgical results.

Abstract
BACKGROUND Rectum resection with total mesorectal excision (TME) and neorectal anastomosis often compromises anorectal function. Insight into the underlying mechanisms is lacking. Therefore, a prospective study was designed to investigate the relationship between clinical and functional outcomes preoperatively and postoperatively. METHODS Eleven patients with rectal cancer were examined before and 4 and 12 months after surgery and compared with 11 healthy volunteers (HVs). Anorectal (neorectal) function was examined by clinical outcome questionnaire, anal manometry, rectal compliance, and sensation. Six HVs also underwent barostat measurements in the sigmoid colon. RESULTS Clinical parameters of soiling and passive incontinence (loss of stool without sensation) increased significantly until 12 months postoperatively, whereas urgency and tenesmus increased temporarily, returning to preoperative values at 12 months. In anorectal measurements, anal sphincter function was grossly preserved; however, rectal-anal inhibitory reflex (RAIR) was decreased at 4 months but recovered after 1 year. Neorectal compliance was similar to that of HV sigmoid, increasing slightly after 12 months but still significantly lower than that of normal rectum. Neorectal sensation to pressure distention was similar to that of normal rectum, however accompanied by smaller volumes. Neorectal distention induced contractions of large amplitude at 4 months, returning to normal after 12 months. CONCLUSIONS Our results suggest that the transient increase in urgency and tenesmus after surgery results from a temporary increase in neorectal "irritability" accompanied by some adaptation of compliance in time. In contrast, episodes of incontinence and soiling are increased after 1 year most likely because of reduced neorectal capacity and RAIR recovery in the presence of a low basal anal sphincter pressure.

Abstract
Abstract
Background
Total pelvic exenteration (TPE) for the treatment of advanced colorectal cancer usually involves a double stoma for faecal and urinary excretion, which reduces patient quality of life. In this study, a stomaless reconstruction method for patients normally requiring TPE was evaluated.
Methods
Five patients underwent stomaless TPE. After removal of the tumour with an adequate surgical margin, the urethra was transected at the urogenital diaphragm and the rectum at the anal canal. An ileal neobladder was constructed and coloanal anastomosis was performed. The major omentum was used to construct a septum between the anastomoses. A transgastric ileus tube was used as an intestinal stent to prevent ileus.
Results
All patients were alive 12–39 months after operation. Faecal continence was preserved in four patients whose diverting colostomies were closed. All five patients were able to void urine spontaneously, with daytime continence. All but one, in whom cancer recurred, were mobile in the community.
Conclusion
Stomaless TPE may be considered for locally advanced colorectal cancers that invade the genitourinary organs, provided that neither the anal canal nor the urogenital diaphragm is affected.

Abstract
OBJECTIVE: The anal sphincters, neorectal capacity and motility may be affected by injury to the autonomic nerves during rectal resection. Anorectal function also depends on the method used for restoration of intestinal continuity, and colonic reservoir reconstruction has been recommended in ultralow anastomosis. This study was undertaken to evaluate the results after nerve preserving mesorectal excision and colorectal anastomosis without a reservoir. PATIENTS AND METHODS: Thirty-five consecutive patients who underwent low anterior resection with primary healing of the anastomosis, were included. Anal manometry with stationary pull through technique, rectal volumetry and symptom scoring (written questionnaires with visual analogue scales) were performed prior to and 12 months after surgery. Anal sphincter function was evaluated in all patients, but five patients with a colonic reservoir were excluded from the other evaluations. Thirty patients entered the main study; 14 patients having a total mesorectal excision (TME) and a low anastomosis (LA) (4-6 cm) and 16 patients a partial mesorectal excision (PME) and a high anastomosis (HA) (7-11 cm from the anal verge). RESULTS: Anal resting and squeeze pressure and rectal sensibility (threshold volume) were unchanged after the operation. The rectal volume eliciting urge to defecate was reduced from median 95 ml to 70 ml (P < 0.01), and the maximum tolerable rectal volume was reduced from 200 to 135 ml (P < 0.01) after the operation. The maximum tolerable volume was significantly lower in patients with LA than in patients with HA (P < 0.01). Overall functional results were good. The patients reported problems with complete bowel emptying (median VAS-score reduction from 90 to 60, P < 0.01), and minor incontinence problems (median VAS-score reduction from 100 to 90, P= 0.03). The reduction of VAS-scores was more pronounced in LA than HA patients (without reaching statistical significance). CONCLUSIONS: Anal sphincter function was preserved after mesorectal excision. Neorectal capacity was reduced, most pronounced in patients with LA. The overall functional results were satisfactory and slightly better in patients with HA than in those with LA.

Abstract
For patients with resectable rectal cancer treated with total mesorectal excision, the routine use of radiotherapy should be omitted for stage I of the disease and for lesions located higher than 10 cm from the anal verge. Preoperative radiotherapy may be considered for all patients with a lesion with deep perirectal fat infiltration located in the lower two thirds of the rectum. The other option is to offer postoperative radiotherapy for patients with a positive surgical margin, N+ stage disease, mesorectal tumour implants, high tumour grade, perineural invasion, extramuscular blood and lymphatic vessel invasion and with inadvertent tumour perforation. The lower risk of small bowel damage and probable higher efficacy are arguments for the use of preoperative radiotherapy instead of postoperative radiotherapy. The impairment of anorectal function appears to be most frequent late postirradiation sequel. The analysis of acute complications (including toxic deaths) compliance, cost and convenience favours 5 x 5 Gy preoperative irradiation with immediate surgery for patients with resectable tumours in comparison to other commonly used schemes of radiotherapy. These advantages should be weighed against approximately 1.5% risk of late neurotoxicity. There is no clear answer to the question whether preoperative conventional radio(chemo)therapy offers an advantage in sphincter preservation. To answer this question, the results of two ongoing randomised trials are awaited. For patients with unresectable cancers, long-term preoperative radio(chemo)therapy with delayed surgery is a preferable scheme. The total mesorectal irradiation should be employed for mid- and low-lying lesions. Therefore, during radiotherapy planning, a contrast enema should be used to identify the anorectal ring, anatomically corresponding with the lowest edge of the mesorectum.

Abstract
Rectal excision followed by low anastomosis is associated with high bowel frequency, urgency and faecal incontinence. These functional disorders results from the loss of the rectal pouch and may be also related to the damage of the anal sphincter or the loss of normal anorectal sensation. Formation of a colonic J pouch reduces the severity of the symptoms of the anterior resection syndrome mainly by decreasing bowel frequency. Creation of a J pouch may also improve the healing of coloanal anastomoses. However, there is no evidence of the role of the colonic J pouch in long term functional outcome of coloanal anastomoses. Moreover, the size of the J pouch increases with time and this may induce evacuation difficulties. Finally, the J pouch cannot be used in all patients, because of technical difficulties especially in obese men. Because the results after colonic J pouch are not perfect, new colonic pouches are developed. The caecal pouch is performed by using an ileocoecal interposition graft between the sigmoid and the anus. The transverse coloplasty is similar to that of stricturoplasty. The side-to-end coloanal anastomosis, giving a colonic blind end, is an other type of pouch. The first procedure seems technically complex with no demonstrated advantage. The second procedure is easy to construct and may be performed in all patients; however, there is a potential higher risk of leakage and functional results must be evaluated. The third procedure showed few advantages compared to a straight anastomosis.

Abstract
This report is based on a series of 108 patients with clinically staged T2 (9), T3 (94) and T4 (5) rectal cancer treated with preoperative irradiation with 25 Gy, 5 Gy per fraction given for one week. In 77% of patients. the tumour was located within 7 cm of the anal verge and in 15% the anal canal was involved. Surgery was usually undertaken during the week after irradiation. For low tumours, total mesorectal excision was performed, and for middle and upper cancers, the whole circumference of the mesorectum was excised at least 2 cm below the lower pole of a tumour. Tumour was resected in 103 patients, and sphincter-preserving surgery was performed in 73% of them. In the subgroup where the tumour was located higher than 4 cm from the anal verge, sphincter-preserving surgery was performed in 95%. The follow-up period ranged from 10 to 49 months, with a median of 25 months. Local recurrences were observed in 4% of patients. Anorectal dysfunction caused impairment of social life in 40% of patients and 18% admitted that their quality of life was seriously affected however, none of them stated that they would have preferred a colostomy. These preliminary data suggest that following high dose per fraction short-term preoperative radiotherapy a high rate of sphincter-preserving surgery can be reached, with acceptable anorectal function and an acceptable rate of local failure and late complications. The results of our own data and literature review indicate the need for a randomized clinical trial comparing high dose per fraction preoperative radiotherapy with immediate surgery with conventional preoperative radiochemotherapy with delayed surgery.

Abstract
Recent advances in surgery have enabled low rectal cancers to be resected, while at the same time restoring bowel continuity and preserving the anal sphincter. Although a permanent stoma is avoided and the operation is oncologically sound, function may be compromised. Many patients with a straight coloanal anstomosis suffer from urgency, incontinence, and bowel frequency-the so-called anterior resection syndrome. Over the last 15 years, surgical developments have aimed at improving function after restoration of bowel continuity, essentially by creating a neorectum. The best known and most widely practiced operation involves formation of a colonic J-pouch. The physiological and functional outcomes of the colonic J-pouch are discussed, along with controversies surrounding construction. Although a J-pouch improves some aspects of function, the results are not perfect. Alternatives to the colonic J-pouch are appraised, indicating future areas of development.
