Horseshoe abscesses and fistulas: how are we doing?
BACKGROUND: Various surgical treatments exist for horseshoe abscesses and fistulae, including posterior midline sphincterotomy, catheter drainage, cutting and draining setons, and advancement flaps. The aim of this study was to evaluate the long-term results of patients treated for these complex anorectal problems. METHODS: A retrospective review was undertaken of patients with a diagnosis of horseshoe abscess, horseshoe fistula, postanal space abscess, or postanal space fistula from 1990 to 2001. Long-term follow-up was accomplished by telephone questionnaire. RESULTS: Thirty-one patients were identified, of whom 17 (54.8%) had a diagnosis of Crohn disease. The diagnosis at presentation included unilateral (ischiorectal) abscess (32.3%), bilateral horseshoe abscess (51.6%), bilateral horseshoe fistula (9.7%), and postanal space abscess (6.4%). Endoanal ultrasonography was used during the preoperative evaluation in 11 patients (35.5%). After referral to our institution, patients underwent a median of four operations (range, 1 to 9). At a mean follow-up of 49.3 months, 60.7% of patients had either healed perineal disease or were asymptomatic with controlled disease. Patients who had a posterior midline sphincterotomy were more likely to be asymptomatic (P=.047). Patients who had a diagnosis of Crohn disease required more operations than those without Crohn disease (3 vs 1.86, P=.02). Only patients who had a diagnosis of Crohn disease had a stoma at their last follow-up (4 of 17, 23.5% vs 0 of 11, 0%; P=.05). CONCLUSIONS: Patients with horseshoe abscess or fistulae often require multiple operations for treatment but can expect reasonable rates of long-term success in controlling or curing their disease. Those who undergo posterior midline sphincterotomy seem to benefit with higher rates of improved symptoms. Patients with a diagnosis of Crohn disease may fare less well. The role of endoanal ultrasonography in directing therapy remains to be defined.

Colorectal cancer screening: do we practice what we preach?
OBJECTIVE: Compliance rates for colorectal cancer screening have been reported as low, and ignorance is the most common factor sighted to explain this. The aim of this study was to determine screening compliance among colorectal surgeons assumed to be educated of the risks of colorectal cancer. METHODS: A postal survey was distributed to the members of the American Society of Colon and Rectal Surgeons. RESULTS: A total of 1195 members were surveyed. All respondents indicated that they advocate screening. Colonoscopy every 10 years and annual fecal occult blood testing were the most common strategies advocated to individuals with baseline risk. Colonoscopy every 5 years and annual fecal occult blood testing were the most common strategies advocated to patients with a first-degree relative with polyps or cancer. Most of these colorectal surgeons initiated their screening before 50 years of age. CONCLUSION: Colorectal cancer screening compliance is high among members of the American Society of Colon and Rectal Surgeons. These rates may be the result of awareness of the risks of colorectal cancer.

Holmium: yttrium aluminium garnet laser lithotripsy for symptomatic Kock pouch calculi.
Kock first described continent ileostomy for fecal diversion in 1969 as an alternative procedure to conventional ileostomy. Later, this procedure was replaced by restorative proctocolectomy with ileal pouch anal anastomosis as the procedure of choice. The main reasons for its virtual abandonment include technical difficulty, high morbidity, and the need for a stoma. To our knowledge, this report is the first published case of successful enterolith destruction and retrieval from a Kock pouch, using a Holmium: yttrium aluminium garnet laser. This outpatient procedure can avoid the morbidity and cost of a laparotomy.

Management of ulcerative colitis in the morbidly obese patient: is bariatric surgery indicated?
Ulcerative colitis and obesity share a systemic chronic inflammatory response manifested by increased inflammatory markers. There are data suggesting a benefit in both diseases after inflammatory markers are decreased. We present a 39-year-old morbidly obese male with a history of ulcerative colitis who manifested significant symptomatic improvement after an 86.8% excess weight loss following gastric bypass surgery. We believe that this result may have been due to a reduction of inflammatory markers secondary to considerable weight loss. Although to our knowledge there are no publications showing a direct relationship between symptomatic improvement of ulcerative colitis and weight loss in the obese patient, we believe that weight loss surgery could become a promising tool in the treatment of ulcerative colitis when associated with morbid obesity.

Correlating the Fecal Incontinence Quality-of-Life Score and the SF-36 to a proposed Ostomy Function Index in patients with a stoma.
Quality of life is affected by the creation of a stoma. To assess the validity of the Ostomy Function Index in patients with a stoma, a prospective survey was conducted from July 2000 to September 2001 among patients participating in local United Ostomy Association chapters (N = 99; 55 with a colostomy and 44 with an ileostomy). The Short Form 36 general health survey, Fecal Incontinence Quality of Life Scale, and the proposed Cleveland Clinic Florida Ostomy Function Index were used to assess general health and stoma function in patients with an ostomy. The average proposed function index score (7 = excellent function, 35 = poor function) was 11.97 (range 7 to 22). The proposed function Index correlated with the Fecal Incontinence Quality of Life Scale and the physical and mental component scales of the SF-36 (P < 0.05). The correlation between the proposed function index and the Fecal Incontinence Quality of Life Scale was stronger in colostomy than in ileostomy patients. With the exception of the SF-36 role-emotional domain in ileostomy patients, the function index correlated with all SF-36 scales (P <0.05) in both patient groups. The results of this study suggest that ostomy function is variable and correlates with quality of life and that the Fecal Incontinence Quality of Life Scale offers a limited assessment of quality of life in colostomy patients. The Cleveland Clinic Florida Ostomy Function Index offers an objective assessment of ostomy function that reflects on quality of life. Additional studies to refine measurement of quality of life in stoma patients are warranted.

Surgical management of rectal prolapse.
BACKGROUND: The problem of complete rectal prolapse is formidable, with no clear predominant treatment of choice. Surgical management is aimed at restoring physiology by correcting the prolapse and improving continence and constipation with acceptable mortality and recurrence rates. Abdominal procedures are ideal for young fit patients, whereas perineal procedures are reserved for older frail patients with significant comorbidity. Laparoscopic procedures with their advantages of early recovery, less pain, and possibly lower morbidity are recently added options. Regardless of the therapy chosen, matching the surgical selection to the patient is essential. OBJECTIVE: To review the present status of the surgical treatment of rectal prolapse. DATA SOURCES: Literature review using MEDLINE. All articles reporting on rectopexy were included. STUDY SELECTION: Articles reporting on prospective and retrospective comparisons were included. Case reports were excluded, as were studies comparing data with historical controls. DATA EXTRACTION: The results were tabulated to show outcomes of different studies and were compared. Studies that did not report some of the outcomes were noted as "not stated." DATA SYNTHESIS: Abdominal operations offer not only lower recurrence but also greater chance for functional improvements. Suture and mesh rectopexy produce equivalent results. However, the polyvinyl alcohol (Ivalon) sponge rectopexy is associated with an increased risk of infectious complications and has largely been abandoned. The advantage of adding a resection to the rectopexy seems to be related to less constipation. Laparoscopic rectopexy has similar results to open rectopexy but has all of the advantages related to laparoscopy. Perineal procedures are better suited to frail elderly patients with extensive comorbidity. CONCLUSIONS: Abdominal procedures are generally better for young fit patients; the results of all abdominal procedures are comparable. Suture and mesh rectopexy are still popular with many surgeons-the choice depends on the surgeon's experience and preference. Similarly, the procedure may be done through a laparoscope or by laparotomy. Perineal procedures are preferable for patients who are not fit for abdominal procedures, such as elderly frail patients with significant comorbidities. The decision between perineal rectosigmoidectomy and Delorme procedures will depend on the surgeon's preference, although the perineal rectosigmoidectomy has better outcomes.

The efficacy of a nerve stimulator (Cavermap) to enhance autonomic nerve identification and confirm nerve preservation during total mesorectal excision.
PURPOSE: Sexual dysfunction after total mesorectal excision may be caused by injury to the autonomic nerves. During surgery, nerve identification is not always achieved, and, to date, there has been no method to objectively confirm nerve preservation. The aim of this study was to assess the efficacy of a nerve-stimulating device (CaverMap) to assist in the intraoperative identification of the autonomic nerves during total mesorectal excision, and objectively confirm nerve preservation after proctectomy is completed. PATIENTS AND METHODS: Sexually active consecutive male patients undergoing total mesorectal excision were prospectively enrolled in this study. During pelvic dissection, the surgeon attempted to localize the hypogastric and cavernous nerves. CaverMap was used to confirm these findings and to facilitate the identification in cases of uncertainty. At the completion of proctectomy, the nerves were restimulated to ensure preservation. Factors that could affect the surgeon's ability to localize the nerves and CaverMap to confirm this were evaluated. RESULTS: Twenty-nine male patients with a median age of 58 years were enrolled in this study. An attempt to visualize the hypogastric nerves during dissection was made in 26 patients; the surgeon was able to identify the nerves in 19 (73 percent) patients. CaverMap successfully identified the nerves in six of the seven remaining patients, and failed to identify them in only one case. An attempt to localize the cavernous nerves during dissection was made in 13 patients, of which localization was successful in 8 (61.5 percent) patients. CaverMap improved the identification rate in four of the remaining five patients. After proctectomy, CaverMap successfully confirmed the preservation of both hypogastric and cavernous nerves in 27 of 29 (93 percent) patients. A history of previous surgery statistically correlated with failure to identify the hypogastric nerves by the surgeon (P = 0.005). There were no adverse events related to use of the device. CONCLUSION: CaverMap may be a useful tool to facilitate identification of the pelvic autonomic nerves during total mesorectal excision and to objectively confirm nerve preservation.

Management of Perianal Crohn's Disease.
Perianal manifestations of Crohn's disease usually coexist with active inflammation of other primary sites of the disease. Although treatment of active proximal disease may sometimes alleviate perianal symptoms, it is reasonable to separately treat symptomatic perianal disease. The diversity of perianal manifestations in Crohn's disease mandates a tailored, individualized approach in every case. Medical therapy is the best treatment option for hemorrhoids and anal fissures. The medical management of patients with perianal Crohn's disease includes the use of systemic antibiotics, immunosuppressive agents, and infliximab. Infliximab is now recognized as a very efficacious agent for treating fistulizing Crohn's disease, including perianal fistulae. It may also reduce the need for surgical intervention in specific cases. Abscesses and fistulae are treated by control of sepsis, resolution of inflammation and optimal preservation of continence, and quality of life. Abscesses require surgical drainage that may need to be prolonged to achieve complete healing. Fistulae may be treated medically, especially in cases of concurrent proctitis. Refractory fistulae may require surgical treatment including an occasional need for fecal diversion or proctectomy. The role of new treatment options such as natalizumab and CDP571 is evolving and requires further investigation.

Pelvic outlet obstruction.
Despite the wide variety of definitions and descriptions of constipation, ideally, the diagnostic approach should be uniform. The evaluation process should begin with a careful and thorough patient history and physical exam; appropriate efforts should be made to exclude organic causes of constipation. Patients suffering from pelvic outlet obstruction often respond poorly to conservative treatment. Diagnostic tests include intestinal transit studies, anorectal manometry, defecography, balloon expulsion, and anal sphincter electromyography. For many patients constipation is multifactorial and accordingly, so is the treatment. In our opinion the first line of treatment should be based on conservative measures including adequate intake of fluids, dietary fiber supplementation, and laxatives. Biofeedback training should be offered, particularly to patients with paradoxical puborectalis contraction. Surgical management can, in very limited circumstances, be offered only to those patients with disabling symptoms who have failed other standard therapeutic measures.

Laparoscopic surgery for ulcerative colitis.
Laparoscopic techniques have revolutionized management of colorectal diseases; however, inflammatory diseases of the intestine have proven challenging because of the technical demands of their nature. Intense investigation and subsequent refinements in technique and technology have recently led to considerable advances and a clear role for laparoscopic management of Crohn's disease. and diverticulitis; laparoscopy for ulcerative colitis has not proven as promising. Laparoscopic procedures for ulcerative colitis require a significant learning curve. Although numerous experienced laparoscopic teams have documented their ability to complete them, long operative times and elevated rates of morbidity in some studies appear to counter the advantages. The question remains as to the universal application and appropriateness of these procedures in surgical management of ulcerative colitis.

Advances in the surgical treatment of fecal incontinence.
Although surgery for fecal incontinence has been shown to be effective, it is still very challenging and sometimes frustrating. Overlapping sphincteroplasty, by far the most common procedure, is effective in patients with sphincter defects; however, recent data suggest that success rates tend to deteriorate over time. A thorough preoperative evaluation incorporates numerous factors, including patient characteristics, severity of incontinence, type and size of the sphincter defect as assessed by physical examination, anal ultrasound, and anorectal physiology studies including anal manometry, electromyography, and pudendal nerve terminal motor latency assessment. The use of these evaluation methods has allowed better patient assignment for a variety of new alternative treatment options. Innovations in the surgical treatment of fecal incontinence range from simple, office-based sphincter augmentation techniques to surgical implantation of mechanical devices. This article reviews 5 alternative surgical treatment options for fecal incontinence: injection of carbon-coated beads in the submucosa of the anal canal, radiofrequency energy delivery, stimulated graciloplasty, artificial bowel sphincter, and sacral nerve stimulation.

Formalin instillation for hemorrhagic radiation proctitis.
Although formalin instillation has been proven to be an effective treatment of hemorrhagic radiation proctitis, different techniques with varying success rates have been reported. The aim of this study was to assess our experience with formalin instillation for the treatment of radiation proctitis. After Institutional Review Board approval, all patients who presented with radiation proctitis and were treated with 4% formalin instillation were identified from a prospective database. Techniques of instillation were as follows: a formalin-soaked sponge stick was applied via a proctoscope (SS) and placed at each quadrant with a mean contact of 2.5 minutes (range, 0.5-3 minutes), or the formalin solution was introduced through a proctoscope in aliquots for a total of 350 to 400 mL irrigation (IR), with a mean contact time of 30 seconds in each aliquot. The patients were divided into two groups according to the method of formalin instillation and their outcomes were compared. Between March 1995 and September 2003, 21 patients who underwent formalin treatment were identified: 17 patients were in the SS and 4 patients were in the IR group. The mean age was 74.8+/-6.4 years and 70.5+/-6.8 years and the male/female ratio was 16:1 and 3:1 in the SS and IR groups, respectively. Indications for radiation therapy were prostate cancer in 19 patients: 16 (95.1%) SS patients and 3 (75%) IR patients. Four (23.5%) patients in the SS group were receiving anticoagulants or antiplatelet medications before the procedure. The mean duration of bleeding before formalin instillation was 11.7 months (range, 2-48 months) in the SS and 10.5 months (range, 7-12 months) in the IR group. Sixteen (94.1%) patients in the SS and 4 (100%) in the IR group had previous treatments for radiation proctitis, including hydrocortisone enema, 5-aminosalicylate mesalamine, and endoscopic coagulation. Eight (47.1%) patients in the SS and 2 (50%) in the IR group received a preprocedural blood transfusion, and 1 patient in the SS group required a blood transfusion after the formalin instillation. This patient subsequently underwent restorative proctosigmoidectomy because of persistent bleeding. The mean length of the procedure was 27.1+/-10.8 minutes in the SS group and 22.5+/-6.5 minutes in the IR group. The bleeding was successfully stopped on the first attempt in 14 patients (82.4%) in the SS group and 3 (75%) in the IR group. The instillation was repeated in 1 patient (5.9%) in the SS group and in 1 (25%) in the IR group. Four patients (23.5%) in the SS group experienced rectal pain after the procedure. One patient (5.9%) developed a new onset of fecal incontinence, while another (5.9%) had anococcygeal pain accompanied by worsening of fecal incontinence. One patient (25%) in the IR group developed acute colitis consistent with formalin instillation, which was managed by intravenous antibiotics. The patients were followed for a mean of 10 months (range, 1 to 38 months). Formalin instillation is effective in controlling refractory hemorrhage secondary to radiation proctitis.

Biofeedback therapy after perineal rectosigmoidectomy or J pouch procedure.
The aim of this study was to determine the outcome and to identify possible predictors of success for biofeedback therapy after perineal rectosigmoidectomy (PRS) or coloanal or ileoanal J pouch. A retrospective chart review of all patients with electromyography-based biofeedback therapy due to fecal incontinence after PRS or a J pouch procedure was undertaken. Follow-up was obtained by telephone survey. Fourteen patients (4 men and 10 women) were included in this study. In the 9 patients after PRS, the frequency of daily bowel movements was 3.6+/-2.8 preoperatively, 4.1+/-3.2 prebiofeedback, and 2.2+/-1.3 postbiofeedback (P<.05). The frequency of daily incontinent episodes was reduced from 2.4+/-2.2 preoperatively and 2.0+/-1.9 prebiofeedback to 0.26+/-0.3 postbiofeedback (P<.05). The incontinence scores decreased from 17+/-3.1 preoperatively to 16+/-2.1 prebiofeedback and to 8.2+/-5 postbiofeedback (P<.001). At a follow-up of 15.8+/-7.1 months, 5 patients after the J pouch had decreased daily bowel frequency from 6.6+/-4.2 prebiofeedback to 3.3+/-2 postbiofeedback and 3.1+/-2 at follow-up (P<.05). The frequency of daily incontinent episodes was reduced from 1.9+/-1.3 prebiofeedback to 0.9+/-0.7 postbiofeedback to 0.7+/-0.8 at follow-up (P<.05). The incontinence scores decreased from 13.4+/-2.7 prebiofeedback to 8.8+/-5.1 postbiofeedback to 6.8+/-5.5 at follow-up (P<0.05). In both groups, the postbiofeedback incontinence score correlated with the prebiofeedback incontinence score. Furthermore, there was no correlation between outcome and age, interval between surgery and biofeedback therapy, frequency of biofeedback sessions, or manometry results in either group. Biofeedback therapy is an effective option for patients with fecal incontinence after perineal rectosigmoidectomy or colonic or ileal J pouch.

Small bowel transit does not correlate with outcome of surgery in patients with colonic inertia.
Colonic inertia is a motility disorder that may involve dysfunction of the entire intestinal tract. The aim of this study was to assess whether small bowel transit time is associated with the outcome of total abdominal colectomy in patients with colonic inertia. A retrospective review of the medical records of patients who underwent total abdominal colectomy for colonic inertia was performed to identify those individuals who had a preoperative small bowel transit study. The outcome of surgery was correlated with the results of the small bowel transit study. Fifty-two female patients underwent total abdominal colectomy for colonic inertia between 1988 and 2000, of whom 17 (33%) had a preoperative small bowel transit study. The small bowel transit time was normal in 11 patients (65%), and the time was abnormally prolonged in 6 (35%). At a mean follow-up of 37 months, there was no significant difference in the outcome of surgery between the two groups. A good result was achieved in 36% of the normal small bowel transit time group compared with 33% in the abnormal group; the result was fair in 63% and 33%, and poor in 0% and 33%, respectively (P=NS). The small bowel transit study does not reliably predict the outcome of total abdominal colectomy in patients with colonic inertia.

Clinical presentation and surgical outcome in patients with solitary rectal ulcer syndrome.
Solitary rectal ulcer syndrome is a poorly understood clinical condition, and the schema of treatment has not yet been defined. This study reviewed the clinical spectra and outcome of various surgical treatments in patients with solitary rectal ulcer syndrome. The medical records of all patients with solitary rectal ulcer syndrome between 1992 and 1998 were retrospectively reviewed. Patients in the study population with symptoms and histopathologic findings suggestive of solitary rectal ulcer syndrome were placed in the primary solitary rectal ulcer syndrome group, and patients who underwent surgery for other diseases in whom histopathology confirmed concomitant solitary rectal ulcer syndrome were in the incidental group. Clinical features and outcomes of surgical treatment were documented. Improvement was considered as resolution of presenting symptoms, and non-improvement was considered if presenting symptoms persisted or worsened. The study cohort comprised 49 patients: 20 in the primary group and 29 in the incidental group. Ulcerative morphology was seen predominantly in the primary group (70%); erythematous (45%) and polypoid lesions (34%) were predominant in the incidental group (P = .0025). Clinical improvement after surgery was seen in 74% of patients with primary and 79% with incidental solitary rectal ulcer syndrome (P = NS). Manifestations such as tenesmus and digitation correlated with poorer outcome after surgery in both groups. Solitary rectal ulcer syndrome is a clinical condition associated with functional anorectal evacuatory disorders. The results of this study show the positive role of surgical treatment for underlying functional disorders in the improvement of incidental solitary rectal ulcer syndrome.
