Restoration of fecal continence after functional gluteoplasty: long-term results, technical refinements, and donor-site morbidity

Baiona's Consensus Statement for Fecal Incontinence. Spanish Association of Coloproctology

Faecal incontinence (FI) is a major health problem, both for individuals and for health systems. It is obvious that, for all these reasons, there is widespread concern for healing it or, at least, reducing as far as possible its numerous undesirable effects, in addition to the high costs it entails. There are different criteria for the diagnostic tests to be carried out and the same applies to the most appropriate treatment, among the numerous options that have proliferated in recent years, not always based on rigorous scientific evidence. For this reason, the Spanish Association of Coloproctology (AECP) proposed to draw up a consensus to serve as a guide for all health professionals interested in the problem, aware, however, that the therapeutic decision must be taken on an individual basis: patient characteristics/experience of the care team. For its development it was adopted the Nominal Group Technique methodology. The Levels of Evidence and Grades of Recommendation were established according to the criteria of the Oxford Centre for Evidence-Based Medicine. In addition, expert recommendations were added briefly to each of the items analysed.

Unstimulated Gluteus Maximus Sphincteroplasty for Bowel Incontinence

Background Gluteus maximus, by virtue of its continued adjunct contraction with the anal sphincter, has many characteristics and histomorphological features mimicking type I musculature. Hence, anal sphincter replacement therapy with gluteus maximus has all avenues for lasting successful results. This study aimed to evaluate the efficiency of unstimulated gluteus maximus sphincteroplasty for anal incontinence reconstruction and neosphincter reconstruction in perineal colostomy cases.

Methods From March 2015 to March 2020, the records of patients who underwent gluteus maximus sphincteroplasty for fecal incontinence were analyzed in this retrospective cohort study. The mean age was 31.55 years. Eleven patients (females = 4, males = 7) underwent anal incontinence reconstruction. All these cases were followed up for an average period of 28.46 months.

Results Good continence was observed in all patients with an average Cleveland Clinic Florida Faecal Incontinence Score of 3.18 (p = 0.0035). At the end of the follow-up period, the average median resting pressure found via manometry was 44.64 mm Hg, and the average median squeeze pressure was 103.55mm Hg. The mean of the average continence contraction time at the end of the follow-up period was found to be 3.64 minutes. None of our patients had complete continence failure. None of our patients used perineal pads or made any lifestyle alterations at the end of the follow-up period. Most of the patients expressed satisfactory continence.

Conclusion Despite being untrained with implantable electrodes, the gluteus maximus muscle produced very good continence results with our way of construct. In addition, with its good lumen occluding effect, it achieves good resting and squeeze anal pressure around the anal canal/bowel with trivial reeducation. Hence, it has become our institution's procedure of choice for anal sphincter reconstruction.

Composite Antropyloric Valve and Gluteus Maximus Muscle Wrap for Neoanal Reconstruction: Initial Results

BACKGROUND

Severe fecal incontinence has a significant negative impact on patient well-being. Current surgical methods of total anorectal reconstruction to substitute a colostomy have suboptimal results. A composite graft using antropyloric valve transposition and gracilis wrap has been described with good outcomes. However, this procedure requires extensive training of patients. Gluteus maximus, an accessory muscle for continence, may be better suited for this purpose.

OBJECTIVE

The purpose of this study was to evaluate the outcomes of composite antropylorus-gluteus graft for intractable fecal incontinence.

DESIGN

Patients underwent a 3-stage procedure: antropyloric transposition with diversion stoma followed by gluteus wrap. Stoma was closed after ensuring the anatomic and functional integrity of the graft.

SETTINGS

This study was conducted at a single tertiary care institution.

PATIENTS

Patients who were on permanent colostomy for intractable incontinence or would have had one after abdominoperineal resection were included.

MAIN OUTCOME MEASURES

Endoultrasonography, MRI, loopogram, saline holding test, anal manometry, St. Mark's fecal incontinence score, and personal interviews were used for measurement.

RESULTS

Eleven patients underwent the procedure with a median follow-up of 16 months (range, 13-34 mo). Digital rectal examination revealed a resting tone with a distinct squeeze provided by the composite graft. Radiological imaging confirmed healthy grafts. There was a significant improvement in mean anal manometry values (resting pressure: preoperative = 10.25 mm Hg vs postoperative = 20.45 mm Hg; squeeze pressure: preoperative = 22.63 mm Hg vs postoperative = 105.18 mm Hg) and mean incontinence score postprocedure (preoperative = 22.8 vs postoperative = 8.6). On personal interview, majority of the patients were continent and expressed satisfaction with the procedure.

LIMITATIONS

The study was limited by its small sample size with no control group.

CONCLUSIONS

Composite graft in patients with intractable fecal incontinence can serve as a viable novel method for total anorectal reconstruction. However, it should only be recommended for a highly select group of individuals in a surveillance setting. Its long-term outcomes remain to be determined as well as its risk versus benefit.

Current surgical strategies to treat fecal incontinence

Fecal incontinence is a devastating condition, vastly under-reported, and may affect up to 18% of the population. While conservative management may be efficacious in a large portion of patients, those who are refractory will likely benefit from appropriate surgical intervention. There are a wide variety of surgical approaches to fecal incontinence management, and knowledge and experience are crucial to choosing the appropriate procedure and maximizing functional outcome while minimizing risk. In this article, we provide a comprehensive description of surgical options for fecal incontinence to help the clinician identify an appropriate intervention.

Systematic Review of Surgical Treatments for Fecal Incontinence

BACKGROUND

No systematic review has examined the collective randomized and nonrandomized evidence for fecal incontinence treatment effectiveness across the range of surgical treatments.

OBJECTIVE

The purpose of this study was to assess the efficacy, comparative effectiveness, and harms of surgical treatments for fecal incontinence in adults.

DATA SOURCES

Ovid MEDLINE, EMBASE, Physiotherapy Evidence Database, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine, and the Cochrane Central Register of Controlled Trials, as well as hand searches of systematic reviews, were used as data sources.

STUDY SELECTION

Two investigators screened abstracts for eligibility (surgical treatment of fecal incontinence in adults, published 1980-2015, randomized controlled trial or observational study with comparator; case series were included for adverse effects). Full-text articles were reviewed for patient-reported outcomes. We extracted data, assessed study risk of bias, and evaluated strength of evidence for each treatment-outcome combination.

INTERVENTIONS

Surgical treatments for fecal incontinence were included interventions.

MAIN OUTCOME MEASURES

Fecal incontinence episodes/severity, quality of life, urgency, and pain were measured.

RESULTS

Twenty-two studies met inclusion criteria (13 randomized trials and 9 observational trials); 53 case series were included for harms. Most patients were middle-aged women with mixed FI etiologies. Intervention and outcome heterogeneity precluded meta-analysis. Evidence was insufficient for all of the surgical comparisons. Few studies examined the same comparisons; no studies were high quality. Functional improvements varied; some authors excluded those patients with complications or lost to follow-up from analyses. Complications ranged from minor to major (infection, bowel obstruction, perforation, and fistula) and were most frequent after the artificial bowel sphincter (22%-100%). Major surgical complications often required reoperation; few required permanent colostomy.

LIMITATIONS

Most evidence is intermediate term, with small patient samples and substantial methodologic limitations.

CONCLUSIONS

Evidence was insufficient to support clinical or policy decisions for any surgical treatments for fecal incontinence in adults. More invasive surgical procedures had substantial complications. The lack of compliance with study reporting standards is a modifiable impediment in the field. Future studies should focus on longer-term outcomes and attempt to identify subgroups of adults who might benefit from specific procedures.

Diagnosis and treatment of faecal incontinence: Consensus statement of the Italian Society of Colorectal Surgery and the Italian Association of Hospital Gastroenterologists

Faecal incontinence is a common and disturbing condition, which leads to impaired quality of life and huge social and economic costs. Although recent studies have identified novel diagnostic modalities and therapeutic options, the best diagnostic and therapeutic approach is not yet completely known and shared among experts in this field. The Italian Society of Colorectal Surgery and the Italian Association of Hospital Gastroenterologists selected a pool of experts to constitute a joint committee on the basis of their experience in treating pelvic floor disorders. The aim was to develop a position paper on the diagnostic and therapeutic aspects of faecal incontinence, to provide practical recommendations for a cost-effective diagnostic work-up and a tailored treatment strategy. The recommendations were defined and graded on the basis of levels of evidence in accordance with the criteria of the Oxford Centre for Evidence-Based Medicine, and were based on currently published scientific evidence. Each statement was drafted through constant communication and evaluation conducted both online and during face-to-face working meetings. A brief recommendation at the end of each paragraph allows clinicians to find concise responses to each diagnostic and therapeutic issue.

Adynamic and dynamic muscle transposition techniques for anal incontinence

Gracilis muscle transposition is well established in general surgery and has been the main muscle transposition technique for anal incontinence. Dynamization, through a schedule of continuous electrical stimulation, converts the fatigue-prone muscle fibres to a tonic fatigue-resistant morphology with acceptable results in those cases where there is limited sphincter muscle mass. The differences between gluteoplasty and graciloplasty, as well as the techniques and complications of both procedures, are outlined in this review. Overall, these techniques are rarely carried out in specialized units with experience, as there is a high revision and explantation rate.

Emerging surgical therapies for faecal incontinence

Faecal incontinence is a common condition and is associated with considerable morbidity and economic cost. The majority of patients are managed with conservative interventions. However, for those patients with severe or refractory incontinence, surgical treatment might be required. Over the past 20 years, numerous developments have been made in the surgical therapies available to treat such patients. These surgical therapies can be classified as techniques of neuromodulation, neosphincter creation (muscle or artificial) and injection therapy. Techniques of neuromodulation, particularly sacral nerve stimulation, have transformed the management of these patients with a minimally invasive procedure that offers good results and low morbidity. By contrast, neosphincter procedures are characterized by being more invasive and associated with considerable morbidity, although some patients will experience substantial improvements in their continence. Injection of bulking agents into the anal canal can improve symptoms and quality of life in patients with mild-to-moderate incontinence, and the use of autologous myoblasts might be a future therapy. Further research and development is required not only in terms of the devices and procedures, but also to identify which patients are likely to benefit most from such interventions.

Surgical management of fecal incontinence

The surgical approach to treating fecal incontinence is complex. After optimal medical management has failed, surgery remains the best option for restoring function. Patient factors, such as prior surgery, anatomic derangements, and degree of incontinence, help inform the astute surgeon regarding the most appropriate option. Many varied approaches to surgical management are available, ranging from more conservative approaches, such as anal canal bulking agents and neuromodulation, to more aggressive approaches, including sphincter repair, anal cerclage techniques, and muscle transposition. Efficacy and morbidity of these approaches also range widely, and this article presents the data and operative considerations for these approaches.

Erysipelas of the thigh and the gluteal region: retrospective multicenter analysis of a very rare entity in 39 patients

BACKGROUND

Erysipelas of the thigh and the gluteal region are rarely described and not well characterized. Therefore we aim to describe the prevalence, clinical characteristics, and risk factors of these erysipelas types.

METHODS

The files of 1,423 patients with erysipelas were analyzed. Data from patients with erysipelas of the thigh or the gluteal region were compared between the two groups and with a control group with erysipelas of the lower leg.

RESULTS

The thigh was exclusively affected in 2.1%, and the gluteal region in 0.6% of erysipelas patients. Gluteal erysipelas had conspicuous irregular borders and sometimes appeared bilaterally. Major risk factors for erysipelas of both sites were previous surgical interventions. Gluteal erysipelas was common in patients with the metabolic syndrome and required a more intense antibiotic therapy.

CONCLUSION

Erysipelas of the thigh and the gluteal region are rare and significantly associated with prior surgical disruption of lymphatic vessels.
