Stapled Transanal Rectal Resection for Outlet Obstruction: A Prospective, Multicenter Trial

PURPOSE:This prospective, multicenter trial was designed to assess the safety and effectiveness of a novel technique in the treatment of outlet obstruction caused by the combination of intussusception and rectocele by using a double-transanal, 33-mm circular stapler.METHODS:From January to October 2001, 90 patients with outlet obstruction were operated on and followed (mean, 16.3 ± 2.9 months) by the validated Constipation Scoring and Continence Grading Systems, clinical examination, defecography, and anorectal manometry. Anal ultrasound also was performed in 58 multiparous patients.RESULTS:Operative time and hospital stay were short (mean, 43.3 ± 8.7 minutes and 2.1 ± 0.8 days, respectively), and postoperative pain was minimal. The mean time to resume normal activity was 10.2 ± 4.5 days. Complications were 17.8 percent fecal urgency, 8.9 percent incontinence to flatus, 5.5 percent urinary retention, 4.4 percent bleeding, 3.3 percent anastomotic stenosis, and 1.1 percent pneumonia. All constipation symptoms significantly improved (P < 0.001) without worsening of anal continence. No patient complained of dyspareunia. At postoperative defecography, all patients had a double incisure of the lower rectal outline in the site of anastomosis, with the disappearance of both intussusception and rectocele. Anal pressure was not significantly modified, whereas rectal compliance was restored (P < 0.05). No lesions of anal sphincters caused by the operation were found in multiparous patients. The outcome at one year was excellent in 48 of 90 patients, good in 33, fairly good in 5, and poor in 4.CONCLUSIONS:This novel technique seems to be safe and effective in the treatment of outlet obstruction caused by the combination of intussusception and rectocele. Randomized trials are required to confirm these findings.

Randomised controlled trial between stapled circumferential mucosectomy and conventional circular hemorrhoidectomy in advanced hemorrhoids with external mucosal prolapse

BACKGROUND This randomized prospective study compared the outcome of circular hemorrhoidectomy according to the Hospital Leopold Bellan (HLB) technique (Paris) with Longo stapled circumferential mucosectomy (LSCM) in two homogeneous groups of patients affected by circular fourth-degree hemorrhoids with external mucosal prolapse. METHODS From December 1996 to December 1999, 80 consecutive patients with fourth-degree hemorrhoids and external mucosal prolapse were randomly assigned to two groups. Forty patients (group A: 18 men, 22 women, mean age 50.5 years, range 21 to 82) underwent HLB hemorrhoidectomy, and 40 patients (group B: 15 men, 25 women, mean age 51.0 years, range 29 to 92) underwent LSCM. Before surgery, all patients were selected with a standard questionnaire for symptom evaluation, full proctological examination, flexible rectosigmoidoscopy, dynamic defecography, and anorectal manometry. No significant differences among the two groups were found. All patients were controlled with follow-up questionnaire and with clinical examination at 1, 2, 4, 12, and 54 weeks after the operation. A postoperative manometry was performed 3 months after surgery. RESULTS The length of the operation was significantly lower in group B (25 +/- 3.1 SD versus 50 +/- 5.3 minutes, P <0.001). Mean hospital stay was 3 +/- 0.4 days in group A and 2 +/- 0.5 days in group B (P <0.01). Mean duration of inability to work was 8 +/- 0.9 days in group B and 15 +/- 1.4 days in group A (P <0.001). Postoperative pain was significantly lower in group B (P <0.001). Mean length of follow-up was 20 +/- 8.0 months in group A and 20 +/- 7.8 months in group B. Late complications were similar in the two groups, with 0%, at present, recurrence rate. CONCLUSIONS Our results confirm that both operations are safe, easy to perform, and effective in the treatment of advanced hemorrhoids with external mucosal prolapse. However, the LSCM seems to be preferable owing to the fewer postoperative complications, easier postoperative management, and shorter time to return to work. A longer follow-up is required to confirm the true efficacy of this surgical method.

Laparotomic vs. laparoscopic rectopexy in complete rectal prolapse.

Aim: The aim of this study was to compare the functional and clinical results of laparotomic and laparoscopic rectopexy in 2 homogeneous groups of patients with complete rectal prolapse and fecal incontinence. Methods: Between January 1989 and December 1997, twenty-three patients underwent abdominal rectopexy. Thirteen patients (group A, 12 females and 1 male, mean age 57.3, range 22–76 years), and 10 patients (group B, 10 females, mean age 52.3, range 26–70 years) were submitted respectively to either Wells laparotomic or laparoscopic rectopexy by the same surgical team using the same surgical technique and materials. Before the operation a detailed clinical history was collected, and the patients were studied by inspection and digital examination of the anorectum, proctosigmoidoscopy, pancolonic transit time, dynamic defecography, anorectal manometry and anal electromyography. After the operation all patients underwent perineal physiotherapy, external electric stimulation, and perineal biofeedback. Mean follow-up was 37.1 (range 6–90) months in group A and 25.7 (range 6–49) months in group B. Values were compared by χ2, Mann-Whitney U, and Wilcoxon tests as appropriate. Differences were considered significant at p < 0.05. Results: In both groups dyschezia and fecal incontinence improved significantly (p < 0.05) after the operation. The basal pressure of the anal sphincter, squeezing pressure and rectoanal reflex improved without significance, and anal-perineal pain was not significantly reduced. In group B the postoperative hospital stay was lower than in group A, with a reduction in costs. Conclusion: Laparoscopic Wells rectopexy has the same clinical and functional results as laparotomic rectopexy, but with a shorter postoperative hospital stay and lower costs.

Impact of New Technologies on the Clinical and Functional Outcome of Altemeier's Procedure: A Randomized, Controlled Trial

PurposeA randomized study was performed to assess whether new technologies offer advantages over the conventional technique on the clinical and functional outcome of patients with full-thickness rectal prolapse and fecal incontinence, submitted to Altemeiers procedure with levatorplasty.MethodsBetween January 1999 and December 2003, 58 patients (55 females; mean age, 70.9 ± 11.3 years) with full-thickness rectal prolapse were evaluated with continence score, colonoscopy, anorectal manometry, anal electromyography, and sacral reflex latency; 40 of them were selected and randomly assigned to two groups: 20 patients (Group 1; 19 females, 73.4 ± 10.4 years) were submitted to a conventional operation with monopolar electrocautery and handsewn anastomosis, and 20 (Group 2; 18 females, 71.5 ± 12.2 years) using harmonic scalpel and circular stapler. Patients were followed up with clinical examination, anorectal manometry, and anal electromyography, with mean follow-up 29.3 ± 8.5 and 27.5 ± 9.2 months in Groups 1 and 2, respectively.ResultsOperative time, blood loss, and hospital stay were significantly reduced in Group 2 (P < 0.001), whereas no differences were found in pain score, time to return to normal activity, morbidity, and mortality. Complications were two (10 percent) stenosis in Group 1. Fecal continence score significantly improved in both groups (P < 0.01), whereas anorectal manometry and neurophysiologic data were not significantly modified by the operation. Recurrence rates were 15 and 10 percent in Groups 1 and 2, respectively (P= not significant).ConclusionsThe clinical and functional long-term results of perineal rectosigmoidectomy with levatorplasty are not influenced by surgical instruments and type of coloanal anastomosis. The clinical relevance of the short-term results in high-risk patients should be specifically investigated.

What is the benefit of a new stapler device in the surgical treatment of obstructed defecation? Three-year outcomes from a randomized controlled trial.

PURPOSE: A randomized study was conducted to compare the clinical and functional outcomes of the stapled transanal rectal resection, using the traditional 2 circular staplers and a new, curved stapler device in patients with obstructed defecation caused by rectal intussusception and rectocele. Stapled transanal rectal resection gives good midterm results in patients with obstructed defecation syndrome, but the limited capacity of the casing of the circular stapler and the impossibility to control the positioning of the rectal wall and the firing of staples may result in incomplete removal of the prolapsed tissues, or serious complications. The new curved multifire stapler could avoid these drawbacks. METHODS: From January to December 2006, 100 women were selected, with clinical examination, constipation score, colonoscopy, anorectal manometry, and perineography, and randomly assigned to 2 groups: 50 patients underwent stapled transanal rectal resection with 2 traditional circular staplers (STARR group) and 50 had the same operation with a new, curved multifire stapler (TRANSTAR group). Patients were followed up with clinical examination, constipation score, and colpocystodefecography, with the recurrence rate as the primary outcome measure. RESULTS: Recurrence rates at 3 years were 12.0% in STARR group and 0 in the TRANSTAR group (P = .035). Operating time was significantly shorter in the STARR group (P = .008). Complications were 2 bleeds (4%) in the STARR group and 1 tear of the vagina in the TRANSTAR group. The incidence of fecal urgency was 34.0% in the STARR group and 14.0% in the TRANSTAR group (P = .035). All symptoms and defecographic parameters significantly improved after the operation (P < .001) without differences between groups. CONCLUSIONS: The curved Contour Transtar stapler device did not appear to offer significant advantages over the traditional PPH-01 device during the operation or in the clinical and functional outcomes. However, the lower incidence of fecal urgency and recurrences might justify the higher cost of the new stapler.

Stapled Transanal Rectal Resection in Solitary Rectal Ulcer Associated with Prolapse of the Rectum: A Prospective Study

PurposeAt present, none of the conventional surgical treatments of solitary rectal ulcer associated with internal rectal prolapse seems to be satisfactory because of the high incidence of recurrence. The stapled transanal rectal resection has been demonstrated to successfully cure patients with internal rectal prolapse associated with rectocele, or prolapsed hemorrhoids. This prospective study was designed to evaluate the short-term and long-term results of stapled transanal rectal resection in patients affected by solitary rectal ulcer associated with internal rectal prolapse and nonresponders to biofeedback therapy.MethodsFourteen patients were selected on the basis of validated constipation and continence scorings, clinical examination, anorectal manometry, defecography, and colonoscopy and were submitted to biofeedback therapy. Ten nonresponders were operated on and followed up with incidence of failure, defined as no improvement of symptoms and/or recurrence of rectal ulceration, as the primary outcome measure. Operative time, hospital stay, postoperative pain, time to return to normal activity, overall patient satisfaction index, and presence of residual rectal prolapse also were evaluated.ResultsAt a mean follow-up of 27.2 (range, 24–34) months, symptoms significantly improved, with 80 percent of excellent/good results and none of the ten operated patients showed a recurrence of rectal ulcer. Operative time, hospital stay, and time to return to normal activity were similar to those reported after stapled transanal rectal resection for obstructed defecation, whereas postoperative pain was slightly higher. One patient complained of perineal abscess, requiring surgery.DiscussionThe stapled transanal rectal resection is safe and effective in the cure of solitary rectal ulcer associated with internal rectal prolapse, with minimal complications and no recurrences after two years. Randomized trials with sufficient number of patients are necessary to compare the efficacy of stapled transanal rectal resection with the traditional surgical treatments of this rare condition.

Prospective clinical and functional results of combined rectal and urogynecologic surgery in complex pelvic floor disorders

BACKGROUND The aim of this prospective study was to evaluate the results of combined rectal and urogynecologic surgery in women with associated obstructed defecation, urinary incontinence, or genital prolapse. METHODS One hundred forty-two selected patients with obstructed defecation in isolation or associated with urinary incontinence, enterocele, or genital prolapse were consecutively operated on by stapled transanal rectal resection alone or associated with transobturator tape, vaginal repair of the enterocele, or vaginal hysterectomy, respectively, and followed up by clinical controls and defecography. RESULTS At 2 years, all symptom, quality-of-life, and defecographic parameters had significantly improved in all groups (P < .001). The association with hysterectomy showed higher risk for severe complications, longer operative time, hospital stay, and time of inability (P < .001). Recurrence of urinary incontinence was observed in 3 of 24 patients, while 2 of 21 showed residual vaginal prolapse. CONCLUSION The combination of rectal and urogynecologic surgery is effective, with higher morbidity in the association with vaginal hysterectomy. Randomized trials comparing surgery in 1 and more stages and longer follow-up are necessary for a definitive conclusion.

Trans-obturator colonic suspension during Altemeier’s operation for full-thickness rectal prolapse: preliminary results with a new technique

Utility of Hydrogen and Methane Breath Tests in Combination with X-Ray Examination after a Barium Meal in the Diagnosis of Small Bowel Bacterial Overgrowth after Jejuno-Ileal Bypass for Morbid Obesity

To study why the symptoms of abdominal bloating occurring in a number of patients after jejuno-ileal bypass for morbid obesity become resistant to antibiotics, we used a method which combined a hydrogen breath test after lactulose with an X-ray examination of the abdomen after barium. Ten operated patients with bloating symptoms resistant to antibiotics, ten operated patients without symptoms or with pre-existing symptoms, that had remitted after antibiotic treatment and ten non-operated obese controls were investigated. There was a significant correlation between post-surgical symptoms persisting after antibiotics and the exhalation of large amounts of hydrogen of colonic origin (> 100 parts per million) after lactulose. Furthermore, symptomatic patients had high prevalence of colonic motility disorders (slow transit). In these patients, treatment with a prokinetic (cisapride 40 mg/kg/day for 10 days) reduced colonic transit time, colonic hydrogen production and bloating symptoms. Abdominal symptoms in these patients may therefore have other causes than small-bowel bacterial overgrowth alone. All operated patients with persistent abdominal bloating should therefore be investigated before starting empirical treatment with antibiotics.

Pudendal Neuralgia: A New Option for Treatment? Preliminary Results on Feasibility and Efficacy

OBJECTIVE The aim of this prospective study was to investigate the feasibility and report the short-term results of a new procedure for treatment of pudendal neuralgia, consisting of transperineal injections of autologous adipose tissue with stem cells along the Alcocks canal. METHODS Fifteen women with pudendal neuralgia not responsive to 3-months medical therapy were examined clinically, with VAS score, validated SF-36 questionnaire, and pudendal nerve motor terminal latency (PNMTL). These patients were submitted to pudendal nerve lipofilling. Clinical examinations with VAS, SF36, and PNTML were scheduled during 12 months follow-up, with the incidence of pain recurrence (VAS > 5) as primary outcome measure. Appropriate tests were used for statistics. RESULTS All patients had preoperative increase of pudendal nerve latencies. Twelve patients completed the follow-up protocol. There was no mortality, and no complications. Two patients had no pain improvement and continued to use analgesic drugs. At 12 months VAS significantly improved (3.2 ± 0.6 vs 8.1 ± 0.9, P < 0.001), as well SF36 (75.5 ± 4.1 vs 85.0 ± 4.5 preoperative, P < 0.01), while PNTML showed a nonsignificant trend to a better nerve conduction (2.64 ± 0.04 vs 2.75 ± 0.03 preoperative, P = 0.06). CONCLUSIONS The new technique seems to be easy, with low risk of complications, and with significant improvement of symptoms in the short period. A larger study with appropriate controls and longer follow-up is now needed to assess its real effectiveness.
