    ABSTRACT: The randomized controlled trial (RCT) is the gold standard tool used to evaluate therapeutic interventions. Methodological and ethical aspects should be adequately reported to enable readers to make informed and justified judgments regarding the validity of a trial and the treatment effectiveness. The aim of this study was to evaluate the methodological and ethical qualities of randomized clinical trials in gastrointestinal surgery and to assess the relationship between these two qualities. All of the articles chosen for review reported on phase III randomized controlled gastrointestinal surgical trials were published in 12 international journals during 2006 and 2007. The eligible studies were identified, selected, and then evaluated based on a broad set of predetermined criteria. The methodological quality was evaluated using the Jadad scale, and the ethical quality was evaluated using the Berdeu score. The mean Jadad score was 9.7 ± 1.78. The methodological quality was insufficient in 64 RCTs (37.4 %; Jadad score <9). The mean Berdeu score was 0.36 ± 0.08. The journal impact factor, number of randomized patients, and number of centers correlated with the outcome of the Jadad score, and the journal impact factor, industry funding, and year in which the trial began correlated with the outcome of the Berdeu score. Informed consent from patients was not obtained in 7 % (n = 12) of the RCTs, and research ethics committee approval was not mentioned in 14.6 % (n = 25) of the RCTs. The reporting of gastrointestinal surgery RCTs is less than optimal. In our study, the trials of higher methodological quality were more likely to provide information about their ethical aspects. These results suggest the need for more attention to be paid to the conduct of clinical research and the reporting of ethical aspects. The appropriation of the ethical rules by surgeons involved in human clinical trials could improve the methodology and reporting of RCTs in gastrointestinal surgery.

    ABSTRACT: Two surgical approaches are employed in the treatment of deep infiltrating endometriosis of the rectum (DIER): colorectal resection and nodule excision. In 2009, we introduced a new technique for transanal full thickness disc excision of endometriotic nodules infiltrating the low and middle rectum, using the Contour® Transtar™ stapler (Ethicon Endo-Surgery inc., Cincinnati, OH, USA). The aim of this retrospective study was to describe the technique and to present data on the feasibility of this technique. From April 2009 to October 2010, all patients presenting with DIER and undergoing full thickness excision using the Contour® Transtar™ stapler were enrolled in the study. Pre-, intra- and post-operative data were collected and reported. Six nulliparous women were managed using this technique during the study period. The rectal wall discs removed measured from 40 × 45 to 60 × 50 mm. In two cases, microscopic foci were noted on one of the margins but in four cases the limits were clear. Operating time varied from 180 to 450 min. Four women were completely free of post-operative digestive complaints. Despite the small numbers in this series, our data suggest that the new technique of transanal rectal disc excision using the contour stapler may be applied in patients with infiltrating endometrial nodules of the rectum up to 10 cm from the anal margin and up to 5 cm in diameter. This new procedure promises to be a useful addition to the surgeon's armamentarium in a multidisciplinary approach to deep pelvic endometriosis.

    ABSTRACT: Natural Orifice Transluminal Endoscopic Surgery (NOTES) is an emerging concept which has been recently applied to the field of rectal excision. The authors describe a case of total mesorectal excision using a transanal port and laparoscopic assistance. We described a procedure performed in a 45-year-old for a rectal adenocarcinoma (1 cm wide, T1sm3) 3 cm above the dentate line. The procedure is described in the text and in a didactic video.

    ABSTRACT: Rectal hypercontractility can lead to faecal incontinence (FI). Botulinum toxin (BT) has been used successfully for the treatment of bladder overactivity. This study aimed to evaluate the therapeutic value of intrarectal injections of BT in inhibiting colorectal contractions and relieving FI in patients suffering from FI as a result of overactive rectal contractions. A prospective open study was carried out in Rouen University Hospital. Six patients (four men and two women) with severe FI related to overactive rectal contractions underwent intrarectal submucosal injections of BT placed in three rows of 10, 1-ml injections (50 U/1 ml; Dysport(®)) starting 1 cm above the dentate line and repeated twice, at intervals of 5 cm proximally. The end-points included improvement in the FI score, in faecal incontinence quality of life (FIQL) and of manometric abnormality. All patients reported improvement in the FI score [18.2±1.1 at baseline vs 9.0±1.7 at 3 months (P=0.04)] and in FIQL. Rectal contractile activity was reduced. The frequency of contractions remained unaffected (28.1±6.6/h; P=0.46 vs baseline). High-amplitude contractions of >50 cmH(2)O were significantly decreased in all patients (16.6±3.9 vs 6.6±4.1/h; P=0.03). Patients with an 'overactive rectum' are a heterogeneous group, with varying causes of dysfunction. The dose of BT used was arbitrarily selected. Nevertheless, the study introduces a further therapeutic option in the treatment of FI caused by rectal overactivity.

    ABSTRACT: Vaginal reconstruction following pelvic exenteration surgery for malignant disease is an important step in the physical and psychological rehabilitation of such patients. Planning of such procedures must include a strategy for reconstruction of the vagina and the oncological surgical team must be aware of the surgical techniques available in order to optimally plan and execute such procedures. We described a procedure which involves supralevator exenteration of the pelvis along with primary colorectal anastomosis. A transposed right colon segment is used to reconstruct the vagina and an omental flap is interpositioned between the reconstructed vagina and the colorectal anastomosis. The procedure is described in the text and in a didactic video.

    ABSTRACT: Our aim was to evaluate medium-term results of transvaginal implantation of an artificial anal sphincter in a large series of patients. Women undergoing treatment for severe fecal incontinence at Rouen University Hospital, Rouen, France, from January 2003 through December 2007 were eligible for the study if the fecal incontinence had lasted for 6 months and if they had attempted other therapies without success. All patients received implantation of an artificial anal sphincter via a transvaginal approach. Incontinence was assessed with the Cleveland Clinic Florida Fecal Incontinence Scale (Wexner score). A total of 32 women entered the study. Their median age was 63 (range, 26-79) years. At entry, 20 (63%) had severe destruction and scarring of the perineum, which was a contraindication for implantation via a perineal approach. Nine patients (28.1%) had previously undergone implantation of an AAS which had been removed because of complications, and 5 had had a Pickrell procedure for anal agenesia. No deaths occurred during the study. The device was removed in a total of 9 patients (28.1%): in 7 because of septic adverse events within the first 6 months after the operation, in 1 because of poor function, and in 1 for psychological reasons despite good functional results. Implantation was successful in 23 patients (71.9%), and the device remained activated for a mean follow-up of 41 (range, 18-75) months, with a mean decrease in Cleveland Clinic incontinence score from 18.4 to 6.8 (P < .0001). None of the patients complained of dyspareunia. The transvaginal approach for implantation of an artificial anal sphincter permits treatment of women with fecal incontinence who have severe damage and scarring of the anterior perineum. This route provides an alternative for patients whose only therapeutic option would previously have been a defunctioning stoma.
