Successful overlapping anal sphincter repair: Relationship to patient age, neuropathy, and colostomy formation

BACKGROUND: Fecal incontinence from single anal sphincter defects are surgically remedial and commonly the result of obstetric injuries. Overlapping anal sphincter repair has previously been associated in small series with good results in 69 to 97 percent of patients. OBJECTIVES: The aims of this study were to assess the results of overlapping anal sphincter repair in one institution and to assess the effects of age, presence of a neuropathy, and addition of a temporary colostomy on the success of surgery. METHODS: A study of 57 overlapping anal sphincter repairs in 56 (54 females) patients at the Royal Prince Alfred Hospital during a six-year period was performed. All patients were investigated preoperatively with endoanal ultrasound and concentric needle electromyography. Patients have been assessed prospectively since 1994 with a questionnaire, including a four-point Likert scale of continence level, the St. Marks incontinence scoring system (range, 0–13), the Pescatori incontinence scoring system (range, 0–6), and patient assessment of success or failure of the overlapping anal sphincter repair. A colostomy was selectively formed in conjunction with an overlapping anal sphincter repair in 21 patients (8 preoperatively, 13 simultaneously), and 18 patients had a concomitant neuropathy (3 unilateral, 15 bilateral). RESULTS: After a median follow-up of 18 months, median continence scores overall had improved from St. Marks incontinence scoring 13 to 3 (P<0.0001) and Pescatori incontinence scoring 6 to 2 (P<0.0001). Forty-nine of 57 (86 percent) repairs have been successful, and 8 are considered to be failures. Twenty-one of 27 (78 percent) repairs in patients younger than 40 years of age were successful, as were 28 of 30 (93 percent) repairs in patients older than 40 years of age (P=0.10). Four of 18 (22 percent) repairs associated with a neuropathy failed compared with 4 of 39 (10 percent) without a neuropathy (P=0.21). Improved or normal continence was achieved in 17 of 21 (81 percent) patients with a stoma and overlapping anal sphincter repair and in 32 of 36 (89 percent) patients with an overlapping anal sphincter repair alone (P=0.32). The presence of a stoma did not improve the rate of wound healing by primary intention (62 percent for stomavs. 64 percent for overlapping anal sphincter repair alone;P=0.55). CONCLUSIONS: Single anal sphincter defects can be successfully treated with an overlapping anal sphincter repair. There is no improvement in primary healing with selective stoma formation. Age of the patient and presence of a neuropathy should not detract from proceeding with overlapping anal sphincter repair when singular anal sphincter defects are detected on endoanal ultrasound in muscle that is still active.

Systematic review of randomized controlled trials of the effectiveness of biofeedback for pelvic floor dysfunction

Pelvic floor dysfunction (PFD) is a type of functional constipation. The effectiveness of biofeedback as a treatment remains unclear.

Risk factors for prolonged ileus after resection of colorectal cancer: an observational study of 2400 consecutive patients.

Objective:Prolonged ileus—the failure of postoperative ileus to resolve within a few days after major abdominal surgery—leads to significant medical consequences for the patient and costs to the hospital system. The aim of this retrospective analysis of prospectively collected data was to identify independent preoperative and intraoperative risk factors for prolonged ileus in a large consecutive series of patients who had undergone resection for colorectal cancer. Methods:Patients were drawn from a hospital registry of 2400 consecutive resections over the period 1995–2009. Thirty-four potential predictors of prolonged ileus were analyzed by logistic regression. Results:Prolonged ileus occurred in 14.0% of patients. Statistically significant independent predictors of prolonged ileus were male sex (OR: 1.7, P < 0.001), peripheral vascular disease (OR: 1.8, P < 0.001), respiratory comorbidity (OR: 1.6, P < 0.001), resection at urgent operation (OR: 2.2, P < 0.001), perioperative transfusion (OR: 1.6, P < 0.010), stoma constructed (OR: 1.4, P < 0.001), and operation lasting ≥3 hours (OR: 1.6, P < 0.001). Conclusions:These features can be used to alert medical and nursing staff to patients likely to experience prolonged ileus after bowel resection so that they can be monitored closely in the postoperative period and available treatments targeted toward them. These features may also be useful in the research context to facilitate the more efficient selection of high-risk patients as subjects in clinical trials of prevention or treatment.

Long-Term Functional Outcomes After Laparoscopic and Open Rectopexy for the Treatment of Rectal Prolapse

PurposeLaparoscopic rectopexy to treat full-thickness rectal prolapse has proven short-term benefits, but there is little long-term follow-up and functional outcome data available.MethodsPatients who had abdominal surgery for prolapse during a ten-year period were identified and interviewed to ascertain details of prolapse recurrence, constipation, incontinence, cosmesis, and satisfaction. Additional details on recurrences that required surgery and mortality were obtained from chart review and the State Death Registry.ResultsOf 321 prolapse operations, laparoscopic rectopexy was performed in 126 patients, open rectopexy in 46, and resection rectopexy in 21 patients. At a median follow-up of five years after laparoscopic rectopexy, there were five (4 percent) confirmed full-thickness recurrences that required surgery. Actuarial recurrence rates of laparoscopic rectopexy were 6.9 percent at five years (95 percent confidence interval, 0.1–13.8 percent) and 10.8 percent at ten years (95 percent confidence interval, 0.9–20.1 percent). Seven patients underwent rubber band ligation for mucosal prolapse and seven required other surgical procedures. There was one recurrence after open rectopexy (2.4 percent) and one after resection rectopexy (4.7 percent), and there was no significant difference between groups. Overall constipation scores were not increased after laparoscopic rectopexy, with no significant difference to open rectopexy or resection rectopexy.ConclusionsThis study has demonstrated that laparoscopic rectopexy has reliable long-term results for treating rectal prolapse, including low recurrence rates and no overall change in functional outcomes.

Multicenter Randomized Trial of Centralized Nurse-Led Telephone-Based Care Coordination to Improve Outcomes After Surgical Resection for Colorectal Cancer: The CONNECT Intervention

PURPOSE To investigate the effectiveness of a centralized, nurse-delivered telephone-based service to improve care coordination and patient-reported outcomes after surgery for colorectal cancer. PATIENTS AND METHODS Patients with a newly diagnosed colorectal cancer were randomly assigned to the CONNECT intervention or usual care. Intervention-group patients received standardized calls from the centrally based nurse 3 and 10 days and 1, 3, and 6 months after discharge from hospital. Unmet supportive care needs, experience of care coordination, unplanned readmissions, emergency department presentations, distress, and quality of life (QOL) were assessed by questionnaire at 1, 3, and 6 months. RESULTS Of 775 patients treated at 23 public and private hospitals in Australia, 387 were randomly assigned to the intervention group and 369 to the control group. There were no significant differences between groups in unmet supportive care needs, but these were consistently low in both groups at both follow-up time points. There were no differences between the groups in emergency department presentations (10.8% v 13.8%; P = .2) or unplanned hospital readmissions (8.6% v 10.5%; P = .4) at 1 month. By 6 months, 25.6% of intervention-group patients had reported an unplanned readmission compared with 27.9% of controls (P = .5). There were no significant differences in experience of care coordination, distress, or QOL between groups at any follow-up time point. CONCLUSION This trial failed to demonstrate substantial benefit of a centralized system to provide standardized, telephone follow-up for postoperative patients with colorectal cancer. Future interventions could investigate a more tailored approach.

KARYDAKIS FLAP REPAIR FOR SACROCOCCYGEAL PILONIDAL SINUS DISEASE: HOW IMPORTANT IS TECHNIQUE?

Numerous operative and conservative treatments have been described in the published work for the management of sacrococcygeal pilonidal sinus; yet there remains considerable debate over its ideal treatment. This report is an audit of our results using the Karydakis flap repair in the management of this condition. We analysed prospective data on 70 patients who had had a Karydakis procedure. The length of follow up ranged from 1 to 79 months (median 36 months). Seventy‐one operations were carried out in 70 patients. This included 12 patients (17%) who had previously undergone between one and four procedures (median 2) for recurrent disease. Superficial wound breakdown occurred in 27 patients (38%) and complete wound breakdown occurred in six patients (8.4%). These wounds were allowed to heal by secondary intent. The median time to complete healing for superficial and complete wound breakdown was 80 and 84 days, respectively. Disease recurrence occurred in three patients (4.2%) – two of whom had recurrent disease at the time of this presentation. Of the three patients who had a recurrence after our surgery, two had a superficial breakdown and one had a complete wound breakdown. Sacrococcygeal pilonidal disease has a low recurrence rate when treated by the Karydakis operation involving flattening of the midline cleft. This procedure avoids the need for more complicated flap repairs.

Improving Quality of Life for People with Incurable Large-Bowel Obstruction: Randomized Control Trial of Colonic Stent Insertion.

BACKGROUND: Surgery remains the dominant treatment for large-bowel obstruction, with emerging data on self-expanding metallic stents. OBJECTIVE: The aim of this study was to assess whether stent insertion improves quality of life and survival in comparison with surgical decompression. DESIGN: This study reports on a randomized control trial (registry number ACTRN012606000199516). SETTING: This study was conducted at Royal Prince Alfred Hospital, Sydney, and Western Hospital, Melbourne. PATIENTS AND INTERVENTION: Patients with malignant incurable large-bowel obstruction were randomly assigned to surgical decompression or stent insertion. MAIN OUTCOME MEASURES: The primary end point was differences in EuroQOL EQ-5D quality of life. Secondary end points included overall survival, 30-day mortality, stoma rates, postoperative recovery, complications, and readmissions. RESULTS: Fifty-two patients of 58 needed to reach the calculated sample size were evaluated. Stent insertion was successful in 19 of 26 (73%) patients. The remaining 7 patients required a stoma compared with 24 of 26 (92%) surgery group patients (p < 0.001). There were no stent-related perforations or deaths. The surgery group had significantly reduced quality of life compared with the stent group from baseline to 1 and 2 weeks (p = 0.001 and p = 0.012), and from baseline to 12 months (p = 0.01) in favor of the stent group, whereas both reported reduced quality of life. The stent group had an 8% 30-day mortality compared with 15% for the surgery group (p = 0.668). Median survival was 5.2 and 5.5 months for the groups (p = 0.613). The stent group had significantly reduced procedure time (p = 0.014), postprocedure stay (p = 0.027), days nothing by mouth (p = 0.002), and days before free access to solids (p = 0.022). LIMITATIONS: This study was limited by the lack of an EQ-5D Australian-based population set. CONCLUSIONS: Stent use in patients with incurable large-bowel obstruction has a number of advantages with faster return to diet, decreased stoma rates, reduced postprocedure stay, and some quality-of-life benefits.

Defunctioning of the anorectum

BACKGROUND: Creating a defunctioning stoma for anorectal disease in patients in whom no resection or anastomosis is required appears eminently suited for laparoscopic techniques, with the intended advantages of early recovery, reduced pain, and avoidance of a laparotomy. OBJECTIVES: The study contained herein was undertaken to determine the feasibility of laparoscopic defunctioning stoma formation using a three-port technique (including one at the stoma site) and to compare initial results with a historical control group. METHODS: Duration of operation (anesthetic plus surgery), the time to tolerance of a liquid and then a solid diet, time to passage of flatus and feces, patient morphine requirements in the first 48 hours, and day of discharge were documented. RESULTS: Nineteen laparoscopic stomas were attempted (3 converted to open) and 23 open stomas were formed in the control group. The laparoscopic stoma group had lower morphine requirements (mean, 47.7vs. 89.9 mg;P<0.01), an earlier tolerance of both liquid (mean, 2.1vs. 3.7 days; P<0.01) and solid diets (mean, 3.6vs. 5.5 days;P<0.001), and an earlier time to passage of both flatus (mean, 2.2vs. 3.6 days;P<0.001) and feces (mean, 3.7vs. 5.6 days;P<0.001). Operating time was longer for the laparoscopic group (mean, 176vs. 104 minutes;P<0.001), whereas median time to discharge from hospital was shorter (median, 8vs. 11 days;P=0.014). Postoperative 30-day morbidity occurred in 1 of 19 laparoscopic group patients and 4 of 23 open group patients. CONCLUSIONS: In this select group of patients requiring defunctioning stoma only, laparoscopic surgery is feasible and safe and may have advantages over open procedures of less pain, earlier tolerance of diet, earlier return of bowel function, and a shorter median length of stay.
