Modified H-pouch as an alternative to the J-pouch for anorectal reconstruction.

AIM: A modification is described of the J-pouch to facilitate ileoanal anastomosis in the presence of an anal or anovaginal fistula. METHOD: The bowel is divided at the level of the apex of the J-pouch, the distal limb is advanced to project beyond the proximal limb by 3-5 cm. The pouch is constructed by a side-to-side anastomosis to form the H-pouch with a distal ileal segment, which is passed through the anal canal to form an ileoanal anastomosis. RESULTS: The modification allows the treatment of anal and rectal disorders not resolvable by a usual J-pouch construction, as in cases where a rectal resection is needed for concomitant fistulation or destruction of the anal mucosa. The functional results are similar to those of the J-pouch, with no added postoperative morbidity. This technique helps to avoid permanent stoma in selected cases. CONCLUSION: The modified pouch is relatively simple to perform and can help the surgeon to address complex anorectal disorders.

Enhanced recovery after elective colorectal resection outside a strict fast-track protocol. A single centre experience.

INTRODUCTION: Optimising the management of hospitalised patients is a major concern. In colorectal surgery, the concept of enhanced recovery has been popularised by means of "fast-track" protocols, aiming at patient's discharge on the second postoperative day. Nevertheless, a strict fast-track protocol has several limitations. It is very demanding for the patient and therefore applicable only to a limited number of patients. AIM: In order to optimise, in every aspect, the postoperative recovery of each patient undergoing an elective colorectal resection inside our institution, we set up a "soft" enhanced recovery programme. MATERIAL-METHODS: A retrospective analysis was conducted in 92 patients evaluating the respective impact of protocol application throughout the duration of the hospital stay. RESULTS: When all the required measures of our protocol were correctly implemented, the median discharge day was postoperative day 3 (range 3-5 days). On the contrary, when deviations occurred, they resulted in longer hospital stay (p < 0.001). Patients operated by laparoscopy were discharged earlier than patients operated by laparotomy (p < 0.001). The use of nasogastric tube and postoperative drainage prolonged significantly the length of stay (p = 0.001 and p < 0.001 respectively). When the urinary catheter was not removed or oral feeding not resumed on postoperative day 1, the patients were discharged later (p < 0.001). CONCLUSIONS: There are substantial possibilities of optimising the recovery process after an elective colorectal resection, outside a strict fast-track protocol.

Outcome following laparoscopic and open total mesorectal excision for rectal cancer.

BACKGROUND: There are few reports on the oncological quality of resection and outcome after laparoscopic versus open total mesorectal excision (TME) for rectal cancer in everyday surgical practice. METHODS: Between January 2006 and October 2011, data for patients with mid or low rectal adenocarcinoma who underwent elective TME were recorded in the PROCARE database. A multivariable model and the propensity score as a co-variable in Cox or logistic regression models were used for adjustment of differences in patient mix and non-random assignment of surgical approach. RESULTS: Data for 2660 patients from 82 hospitals were recorded. Implementation of laparoscopic TME was highly variable. The oncological quality of resection was similar in the laparoscopic and the open group: incomplete mesorectal excision in 13·2 and 11·4 per cent respectively, circumferential resection margin positivity in 18·1 per cent, and a median of 11 lymph nodes examined per specimen in both groups. The hazard ratio for survival after laparoscopic versus open TME was 1·05 (95 per cent confidence interval 0·88 to 1·24) after correction for differences in patient mix, and 1·06 (0·89 to 1·25) after correction for the propensity score. The definitive colostomy rate was similar in the two groups: 31·0 per cent after open and 31·4 per cent after laparoscopic TME. Postoperative morbidity was lower and length of stay was shorter after laparoscopic TME compared with open TME. Survival was not negatively affected by converted laparoscopic resection, whereas postoperative morbidity, mortality and length of stay after converted laparoscopy were comparable with those after open TME. CONCLUSION: Oncological outcome is comparable after laparoscopic and open TME in everyday surgical practice.

Risk adjusted benchmarking of clinical anastomotic leakage rate after total mesorectal excision in the context of an improvement project.

AIM: Anastomotic leakage (AL) after total mesorectal excision (TME) is a major adverse event. This study evaluates variability in AL between centres participating on a voluntary basis in PROCARE, a Belgian improvement project, and how further improvement of the AL rate might be achieved. METHOD: Between January 2006 and March 2011, detailed data on 1815 patients (mean age 65.5 years, 63% male) who underwent elective TME with colo-anal reconstruction for rectal cancer were registered by 48 centres. Variability in early clinical AL rate was analysed before and after adjustment for gender, age > 60 years, American Society of Anesthesiologists score of 3 or more and body mass index > 25 kg/m(2). RESULTS: The overall AL rate was 6.7% (95% CI 5.6%-7.9%). Early AL required reoperation in 86.8% of patients. It increased length of hospital stay from 14.7 days to 32.4 days and in-hospital mortality from 1.1% to 4.8%. Statistically significant variability in AL rate between centres was not observed, either before or after risk adjustment. Nonetheless, further improvement may be achievable in some centres by targeting the adjusted performance of better performing centres. These centres used neoadjuvant treatment, rectal irrigation, mobilization of the splenic flexure, resection of the sigmoid colon, side-to-end colo-anastomosis with or without pouch and defunctioning stoma at primary surgery in a significantly higher proportion of patients than less well performing centres. CONCLUSION: The overall AL rate was low but needs to be interpreted with caution because of incomplete registration. Further improvement might be achieved by adopting the approach of better performing centres.

Short course chemotherapy followed by concomitant chemoradiotherapy and surgery in locally advanced rectal cancer: a randomized multicentric phase II study.

BACKGROUND: Induction chemotherapy has been suggested to impact on preoperative chemoradiation efficacy in locally advanced rectal cancer (LARC). To evaluate in LARC patients, the feasibility and efficacy of a short intense course of induction oxaliplatin before preoperative chemoradiotherapy (CRT). PATIENTS AND METHODS: Patients with T2-T4/N+ rectal adenocarcinoma were randomly assigned to arm A-preoperative CRT with 5-fluorouracil (5-FU) continuous infusion followed by surgery-or arm B-induction oxaliplatin, folinic acid and 5-FU followed by CRT and surgery. The primary end point was the rate of ypT0-1N0 stage achievement. RESULTS: Fifty seven patients were randomly assigned (arm A/B: 29/28) and evaluated for planned interim analysis. On an intention-to-treat basis, the ypT0-1N0 rate for arms A and B were 34.5% (95% CI: 17.2% to 51.8%) and 32.1% (95% CI: 14.8% to 49.4%), respectively, and the study therefore was closed prematurely for futility. There were no statistically significant differences in other end points including pathological complete response, tumor regression and sphincter preservation. Completion of the preoperative CRT sequence was similar in both groups. Grade 3/4 toxicity was significantly higher in arm B. CONCLUSIONS: Short intense induction oxaliplatin is feasible in LARC patients without compromising the preoperative CRT completion, although the current analysis does not indicate increased locoregional impact on standard therapy.

Different surgical strategies in the treatment of familial adenomatous polyposis: what's the role of the ileal pouch-anal anastomosis?

BACKGROUND AND STUDY AIMS: Restorative coloproctectomy (RCP) with ileal pouch-anal anastomosis (IPAA), is one of the surgical responses to the crucial question of prophylactic treatment in familial adenomatous polyposis (FAP). No consensus has been reached, until now, to choose between IPAA and ileo-rectal anastomosis (IRA), the rectal sparing prophylactic colectomy. This paper aims to review the latest issues related to IPAA and highlights its specificities compared to IRA. METHODS: PubMed database was searched using the following search items: familial adenomatous polyposis, surgery, ileal pouch-anal anastomosis, ileo-rectal anastomosis. Papers published between 1978 and 2010 were selected. RESULTS: Absence of mortality, acceptable morbidity and good functional results combined to high quality of life have promoted the IPAA technique. New technical issues such as the double stapled technique, mesenteric lengthening, omission of temporary protective stoma can be addressed almost systematically for these patients. A laparoscopic approach, lessening the body image impact, has proven to be as effective and safe as the open approach to perform IPAA. Further advantages of laparoscopic IPAA rely on the lower adhesion formation resulting in less small bowel occlusion. Sexuality, fertility and childbirth are important functional issues often cited as threatened by the pelvic manoeuvres of the IPAA technique which can be prevented by close rectal wall dissection and a laparoscopic approach. CONCLUSION: IPAA offers the best available prophylaxis in FAP patients. Technical enhancements in IPAA will most probably decrease the functional risks. Thus IPAA remains the alternative to IRA for the prophylactic treatment of FAP.Nevertheless, based on the latest evidence, the choice between both procedures is still matter of debate.

Quality of care indicators in rectal cancer.

Quality of health care is a hot topic, especially with regard to cancer. Although rectal cancer is, in many aspects, a model oncologic entity, there seem to be substantial differences in quality of care between countries, hospitals and physicians. PROCARE, a Belgian multidisciplinary national project to improve outcome in all patients with rectum cancer, identified a set of quality of care indicators covering all aspects of the management of rectal cancer. This set should permit national and international benchmarking, i.e. comparing results from individual hospitals or teams with national and international performances with feedback to participating teams. Such comparison could indicate whether further improvement is possible and/or warranted.

[Organized colorectal screening in French Community of Belgium and polyp surveillance]. / Le dépistage organisé du cancer colorectal en Communauté française de Belgique et surveillance des polypes.

Colorectal cancer is an important health care problem in Belgium and screening is now widely recommendend. The French Community has launched in March 2009, a campaign to build public and professional awareness of the importance of screening for colorectal cancer. With the goal of encouraging all persons age 50 to 74 to actively gain information and seek screening with the active participation of their house doctors, the campaign will work to clarify any myths or fears about screening options and ensure that the importance of screening and early detection will be understood. The program in the French Community propose guaiac-based fecal occult blood testing for average risk people and, in case of positivity a colonoscopy must be performed. A high quality colonoscopy should be offered first in case of significant personal and familial history of adenomas, colorectal cancer and some specific extracolonic neoplasia. Several strategies will be used to ensure follow up of this program and encourage wide participation of the population.

Elective colorectal surgery without bowel preparation: a historical control and case-matched study.

BACKGROUND: Although full bowel preparation, including mechanical washout and non-absorbable antibiotherapy, has been considered for decades as a prerequisite to any elective colorectal surgery, recent literature has suggested that this habit was perhaps unjustified. The aim of this study was to assess the safety of ileocolic, colocolic and colorectal anastomosis in the absence of pre-operative mechanical bowel preparation. METHODS: During a 1-year period, 59 consecutive patients underwent elective colorectal surgery with ileocolic, colocolic or colorectal anastomosis without any pre-operative preparation. This "non-prepared group" (NPG) was compared to a "control group" (CG) composed of the previous 127 consecutive cases of classically managed patients. To improve the statistical power we also compared the NPG to a "match-controlled group" (MCG) of 59 patients within the CG. Primary end-points were anastomotic leakage and abdominal infections. Secondary end-points were oral diet resume time and hospital stay. RESULTS: There were no differences between the 3 groups for age, gender, BMI, immunodepression status, anastomosis site and suture technique. There were no differences between NPG and CG or MCG for anastomotic leakage (3.5%, 4.7% and 6.8% respectively, NPG/CG p = 0.68 and NPG/MCG p = 0.4) or for infectious abdominal complications. Mean diet resume time was 1.4 (1-5) days in the NPG versus 3.4 (1-19) days in the CG and 3.1 (1-6) days in the MCG (p < 0.00001). Median length of postoperative hospital stay was 5 (2-81) days in the NPG versus 8 (4-100) and 8 (4-100) in the CG and the MCG respectively. CONCLUSIONS: In accordance with the recent literature, the present experience does not show any benefit of mechanical bowel preparation in elective colorectal resection. This suggests that bowel preparation could be omitted before this type of surgery.

Tailgut cyst associated with a carcinoid tumor: case report and review of the literature.

We report the case of a 49-year-old woman who presented a tailgut cyst lined by a variety of epithelium including squamous, columnar and transitional. Fortuitously a microscopic carcinoid tumor expressing immunohistochemically neuroendocrine markers was identified in the cystic wall. Tailgut cysts are congenital abnormalities located in the presacrococcygeal area occurring usually in adult patients. Clinical diagnosis is difficult because they are often asymptomatic. Patients may present symptoms resulting from local mass effects or complications. The differential diagnoses include rectal duplication cysts, cystic sacrococcygeal teratomas, epidermal cysts, epidermoid cysts, anal duct or gland cysts. Magnetic resonance imaging has recently become the modality of choice to image the cyst. Malignant transformation is rare; 23 cases including 10 carcinoid tumors have been reported in the literature. To our knowledge, this is the eleventh case of carcinoid tumor arising in a tailgut cyst.

Long-term results after excision haemorrhoidectomy versus stapled haemorrhoidopexy for prolapsing haemorrhoids; a Belgian prospective randomized trial.

PURPOSE: To compare the postoperative evolution and the long-term efficacy after stapled haemorrhoidopexy (PPH) and Milligan-Morgan haemorrhoidectomy (MM). METHODS: In a prospective randomized study, 40 patients requiring surgical treatment for prolapsing haemorrhoids grade II or III were assigned to either MM or PPH (20 each). Postoperative pain, wound healing were evaluated, as well as anal pressures and sphincter anatomy. Mean follow-up is 46 months. RESULTS: Postoperative pain at rest and during defecation was less important after PPH if no resection of external piles or skin tags was associated (P < 0.0001). Healing time was shorter after PPH (P < 0.0001). Endoanal ultrasound remained unchanged postoperatively. Resting and squeeze pressures decreased after MM, but not after PPH (P < 0.01). After a mean follow-up of 46 months (12-56), persistent or recurrent symptoms, mostly mild and temporary, were observed after both MM and PPH, in 7 and 11 patients respectively (NS). After PPH, five patients (25%) complained of recurrent external swelling and/or prolapse (P = 0.047 vs. MM) requiring redo surgery in four of them, after 10, 13, 14 and 21 months. No redo-surgery was required after MM. Long term patient satisfaction after PPH was not better than after MM. CONCLUSIONS: Postoperative pain is less important after PPH. This advantage disappears if any resection is associated with the stapling. At medium to long-term follow-up, PPH seems to carry a higher risk of symptomatic external haemorrhoidal disease, needing further surgery.

Preferential infiltration of large bowel endometriosis along the nerves of the colon.

BACKGROUND: Little is known about the mode and the extent of infiltration of endometriotic lesions in the large bowel. METHODS: In 31 patients undergoing large bowel resection for severe deep-infiltrating endometriosis of the sigmoid and rectum with severe digestive symptoms, we performed a prospective morphological, histological and immunohistological study (using the monoclonal antibodies S100 for the detection of the nerves and CD10 for the detection of the endometriotic stromal cells) on the large bowel resection specimen. The evaluation of invasion of the large bowel by endometriosis was performed by studying the presence, localization and mean number of lesions in the different layers of the colon, the relationship between endometriosis and the nerves of the colon, the nerve density in the respective layers of the large bowel and the presence of endometriosis on the resection margins. RESULTS: The most richly innervated layers of the large bowel are the most intensely involved by endometriosis. We found that 53 +/- 15% of endometriotic lesions were in direct contact the nerves of the colon by means of perineurial or endoneurial invasion. The mean largest diameter of the lesion does not seem to be correlated with the depth of infiltration. The margins were positive in 9.7% of cases. In cases of positive margins, the endometriotic lesions were in close histological relationship with the nerves. CONCLUSIONS: There is a close histological relationship between endometriotic lesions of the large bowel and the nerves of the large bowel wall. Endometriotic lesions seem to infiltrate the large bowel wall preferentially along the nerves, even at distance from the palpated lesion, while the mucosa is rarely and only focally involved.

Warty carcinoma of the anus: a variant of squamous cell carcinoma associated with anal intraepithelial neoplasia and human papillomavirus infection.

Warty carcinoma (WC) is a rare variant of squamous cell carcinoma primarily described in the vulva in younger women and classically associated with human papillomavirus (HPV) infection. The gross findings are similar to those of verrucous carcinoma with large, exophytic tumors with a papillomatous surface. Microscopically, the tumor is papillated and contains fibrovascular cores covered by hyperkeratotic epithelium showing presence of koilocytes. We report a case of anal squamous cell carcinoma showing similar features, occurring in a young immunosuppressed male patient with a history of multifocal anal intraepithelial neoplasia (AIN). HPV-16 has been demonstrated both in the WC and in adjacent AIN, but the HPV status appears different in the two lesions: integrated in WC and episomal in AIN lesions. We also have demonstrated by immunohistochemistry that both WC and AIN are highly proliferative entities sharing the same MIB-1 pattern, and that WAF1/CIP1 protein expression is common in the two lesions irrespective of p53 protein expression.

[Preoperative evaluation of rectal cancer]. / Evaluation préopératoire du cancer du rectum.

For a patient with a rectal tumor, the preoperative staging should answer four questions: Is the rectal tumor unique? Is the patient operable? Are there distal metastases? What is the loco-regional extension? The loco-regional extension is well evaluated by the echo-endoscopy while the involvement of the surrounding organs is better assessed by CT-scan or resonance magnetic imaging.

[Treatment of colorectal cancer: a resolute multidisciplinary approach]. / Le traitement du cancer colorectal: une approche résolument multidisciplinaire.

Significant developments have been occurred in the field of colorectal cancer treatments over these last years, surgery clearly remaining the only curative therapy. Optimalized surgical approaches, such as total mesorectum excision, aggressive resections of liver metastases and development of innovative techniques of local destruction of hepatic lesions using radiofrequency attempt to prolong survival. New chemotherapeutic and biological agents, associated with a better knowledge of tumor biology open promising perspectives with regards to an increasing of survival, an improvement of quality of life and the possibility to resect curatively liver metastases initially unresectable, after neoadjuvant chemotherapy. The present paper aims to review the therapeutic approaches at the different stages of the disease and strongly insists on the multidisciplinary strategy required for an optimal management and a global view of colorectal cancer, shared by the surgeon, the gastroenterologist and/or the oncologist and the radiotherapist.

Fistula in ano: the place of rectal advancement flap technique.

Classical surgical techniques for anal trans- or suprasphincteric fistulas imply the division of the sphincters likely to induce postoperative continence impairment. The rectal advancement flap technique achieves healing of the fistula in a significant number of patients, while avoiding any sphincter division, and therefore the development of further incontinence.
