Comparison of Botulinum Toxin Injection and Lateral Internal Sphincterotomy for the Treatment of Chronic Anal Fissure

AbstractPURPOSE: Botulinum toxin injection into the internal anal sphincter has been shown to be an effective treatment for chronic anal fissure. A randomized, prospective trial was conducted to compare botulinum toxin with lateral internal anal sphincterotomy as definitive management for chronic anal fissure. METHODS: Patients diagnosed as having chronic anal fissure were randomly assigned to one of the two treatment arms. In the botulinum toxin group (n = 61), 20 to 30 U (approximately 0.3 U/kg) of type A botulinum toxin (Botox®) was injected into the internal anal sphincter. The injection was repeated two months later if complete healing was not accomplished. Patients in the sphincterotomy group (n = 50) underwent lateral internal anal sphincterotomy. The same investigators evaluated the patients on postoperative/postinjection days 7 and 28, and then in a blinded manner at 2, 6, and 12 months. RESULTS: In the botulinum group, single injection resulted in complete healing in 45 of the 61 patients (73.8 percent) at the second month. Of the 16 failures, 6 patients refused further treatment, and 10 were treated with a second injection, which resulted in an overall healing rate of 86.9 percent (53/61) at 6 months. In the sphincterotomy group, the success rate was 82 percent (41/50) at day 28 and 98 percent (49/50) at the second month (P = 0.023 and P < 0.0001, respectively, compared with the botulinum group—single injection). At 6 months, 2 patients in the LIS group developed recurrences, and the healing rate was similar to that of the botulinum group (86.9 vs. 96.4 percent; P = 0.212). At 12 months, the success rate of the Botox® group fell to 75.4 percent (46/61) with 7 recurrences, whereas it remained stable in the sphincterotomy group (94 percent, P = 0.008). Sphincterotomy was associated with a significantly higher complication rate (8 cases of anal incontinence vs. none in the botulinum toxin group; P < 0.001). Full return to daily activities took significantly less time in the botulinum group (1 vs. 14.8 ± 5.7 days; P < 0.0001). CONCLUSION: Although the healing rate of chronic anal fissure is considerably high with botulinum toxin injection with earlier recovery and less complications compared with sphincterotomy, it occasionally requires a repeat injection, and the healing is slower. The early (two months) and late (one year) healing rates are significantly higher in the sphincterotomy group, the two groups reaching similar healing rates only at six months.

Modified Limberg Transposition Flap for Sacrococcygeal Pilonidal Sinus

Purpose.To investigate the results of wide rhomboid excision with Limberg transposition flap reconstruction to treat pilonidal sinus.Methods.We analyzed the well-documented records of 238 patients with sacrococcygeal pilonidal sinus who underwent wide excision with a Limberg transposition flap and were followed up for longer than 1 year postoperatively. After the first 40 operations, we modified this flap reconstruction by tailoring the rhomboid excision asymmetrically to place the lower pole of the flap 1–2 cm lateral to the midline. Wound infection rates, hospitalization, time required for free mobilization, and recurrence rates were recorded.Results.Postoperative infection developed in two patients (0.8%), which was easily managed by wound care, antibiotics, removal of skin staples, prolonged drainage, or a combination of these treatments. The mean hospitalization was 2.10 ± 0.20 days (range 1–3 days), and the mean time required for recovery and return to daily activities was 8.00 ± 2.50 days (range 4–17 days). There were only three recurrences (1.26%) after a mean follow-up of 29.20 ± 3.10 months (range 12–38 months). Since we started performing our modification of the technique by lateralization of the inferior apex, no further recurrences have been seen. The recurrence rate differed significantly between the classical Limberg flap group and the modified Limberg flap group (P = 0.004)Conclusion.These results provide further evidence that wide excision with a Limberg transposition flap reconstruction is an effective surgical method for primary or recurrent pilonidal sinus, associated with a low complication rate, short hospitalization and disability, and a low recurrence rate. A modification of the technique was devised to further enhance wound healing and reduce the risk of recurrence.

Modified Limberg flap reconstruction compares favourably with primary repair for pilonidal sinus surgery

Background:  The present study analyses the results of wide excision with primary closure (PC), wide excision with classical Limberg flap reconstruction (LF) and wide excision with modified Limberg flap reconstruction (MLF) in the surgical treatment of sacrococcygeal pilonidal disease.

Comparison of the classic limberg flap and modified limberg flap in the treatment of pilonidal sinus disease: A retrospective analysis of 416 patients

PurposePilonidal sinus disease (PSD) is usually seen on the sacrococcygeal region in adolescent patients. The current study analyzed the outcome of the rhomboid excision and the Limberg flap procedure (cLF) in comparison to the modified Limberg flap procedure (mlF) for PSD.MethodsFour hundred and sixteen patients with PSD were operated on under spinal or general anesthesia by cLF and mlF. The patients were divided into two groups. In Group 1, cLF was performed on 211 patients. In Group 2, mlF was performed on 205 patients.ResultsNo significant difference was detected between Groups 1 and 2 in terms of sex, age, preoperative disease period, follow-up time, the mean hospital stay, and hypoesthesia. The mlF group had better clinical results than the cLF group. The recurrence rate was statistically higher in the cLF group 1 than in the mlF group (P = 0.036). The time to return to work, time to walk without pain, and time to be able to sit on the toilet without pain were longer in the cLF group (P = 0.001). The maceration and wound infection rate were statistically higher in the cLF group than in the mlF group (P = 0.020 and P = 0.019, respectively).ConclusionThe mlF is a more effective treatment than cLF for the surgical management of PSD.

Results of Lateral Internal Sphincterotomy for Chronic Anal Fissure With Particular Reference to Quality of Life

PurposeThe aim of this study was to investigate the effects of lateral internal sphincterotomy on quality of life in patients with chronic anal fissure using the Gastrointestinal Quality of Life Index and the Fecal Incontinence Quality of Life Scale.MethodsAdult patients with chronic anal fissure underwent lateral internal sphincterotomy with the open technique. Two hundred forty-four patients completed the Gastrointestinal Quality of Life Index questionnaire at admission and at 12 months postoperatively. The Fecal Incontinence Severity Index score was calculated preoperatively and at 2 and 12 months postoperatively. The Fecal Incontinence Quality of Life Scale was administered to any patient who had a Fecal Incontinence Severity Index score greater than 0 at 12 months postoperatively.ResultsThe mean preoperative Gastrointestinal Quality of Life Index score was 118.34 ± 6.33, which developed to 140.74 ± 2.38 postoperatively (P< 0.001). At the two-month follow-up, 18 patients (7.38 percent) had a Fecal Incontinence Severity Index score greater than 0. By 12 months, the number of patients with Fecal Incontinence Severity Index score greater than 0 was reduced to seven (2.87 percent). These seven patients had a Gastrointestinal Quality of Life Index score similar to that of the group with postoperative Fecal Incontinence Severity Index score of 0, and only three patients (1.22 percent) had evident deterioration in the Fecal Incontinence Quality of Life Scale. The 12-month total Gastrointestinal Quality of Life Index score of the three patients who developed anal abscess/fistula after sphincterotomy (139.33 ± 3.21) was similar to the Gastrointestinal Quality of Life Index score of those without complications. However, the Gastrointestinal Quality of Life Index score of the recurrent cases (111.53 ± 3.53) was apparently low.ConclusionThe gastrointestinal quality of life improved significantly following lateral internal sphincterotomy, regardless of the surgical complications or postoperative disturbances of continence. Only 1.2 percent of the patients experienced deterioration in Fecal Incontinence Quality of Life Scale.

Extent of Lateral Internal Sphincterotomy: Up to the Dentate Line or Up to the Fissure Apex?

PURPOSEThe aim of this randomized, prospective study was to compare the results of lateral internal sphincterotomy up to the dentate line or up to the fissure apex in the treatment of chronic anal fissure.METHODSAdult patients with chronic anal fissure were randomly assigned to undergo lateral internal sphincterotomy to the level of the dentate line or to the level of the fissure apex. The patients were reexamined on postoperative Days 1, 7, 14, 28, and then at 2 and 12 months.RESULTSThe time required for relief of pain postoperatively was 2.08 ± 1.44 days in the dentate line group, which was significantly shorter than that for the fissure apex group (4.72 ± 4.86 days; P = 0.002). Objective healing was achieved in 23.7 percent and 17.6 percent at 14 days, 97.4 percent and 88.2 percent at 28 days, and 100 percent and 97.7 percent at 2 months in the dentate line and fissure apex groups, respectively (P > 0.05 for all comparisons). Only sphincterotomy up to the dentate line caused a significant change in anal incontinence (P = 0.016). Both groups had significantly lower anal resting pressures at 4 months postoperatively, compared with their corresponding preoperative levels (P = 0.005 and P = 0.007). The postoperative resting pressures did not differ significantly between the two groups (P = 0.273). By 12 months postoperatively, no treatment failures or recurrences were noted in the dentate line group (100 percent healing rate). In the fissure apex group, there was one nonhealing case and four recurrences, resulting in a 13.2 percent rate of treatment failure (P = 0.058).CONCLUSIONSSphincterotomy up to the dentate line provided a faster and definitive healing within the time limits of this study, but it was associated with a significant alteration in anal continence. In turn, sphincterotomy up to the fissure apex was free of significant disturbance of continence, but its healing effect was slower and it was prone to an insignificantly higher rate of treatment failure.

Elastic one-stage cutting seton for the treatment of high anal fistulas: preliminary results

BackgroundThe management of high and complicated anal fistulas remains a therapeutic challenge, and the oldest and theoretically the simplest technique is to use a seton. In this article, we document our recent experience in managing high anal fistulas with a simple modification of the cutting seton.Patients and methodsSurgical outcomes of patients treated by the elastic cutting seton for anal fistulas that involved more than half of the sphincter muscles or for anterior trans-sphincteric fistulas in female patients were analyzed. The elastic seton, which was created by cutting a thin (2–3 mm) circular strip from a surgical glove, including its thicker sleeve, was inserted through the remaining tract in a double-strand fashion, and then tied on the sphincter with two knots in a slightly tight manner.ResultsComplete healing was achieved in 9 cases (45%) at 1 month and in all cases (100%) at 3 months postoperatively. Recurrent fistula was noted in a single patient (5%) at 8 months. Worsening of preoperative continence was noted in 4 patients (20%). However, the postoperative incontinence score (0.70±1.22) did not differ significantly from the preoperative score (0.41±0.41; p=0.059, Wilcoxon’s test).ConclusionsThe preliminary results of this series suggest that the elastic cutting seton may be a valid alternative for the treatment of high anal fistulas. The possible positive contribution of the slow and stable cutting of the sphincter on the maintenance of continence is further supported. An important practical disadvantage of the conventional seton treatment, namely the need for postoperative adjustments, is also eliminated.

Intradermal methylene blue injection for the treatment of intractable idiopathic pruritus ani: results of 30 cases.

Abstract.Some cases of idiopathic pruritus anu may be refractory to treatment with dietary and hygienic instructions and short-term topical medications. In this study, we documented our technique and results with methylene blue injection in a large series of patients with intractable idiopathic pruritus ani. The results of 30 adult patients with well-documented intractable idiopathic pruritus ani who were treated with intradermal methylene blue injection are reported. No antibiotic prophylaxis, anesthesia or sedation was used. A total of 15 ml of a 1% methylene blue solution was injected intracutaneously and subcutaneously in the affected perianal area. A second injection (rescue treatment) was offered one month later to patients who declared partial response, and follow-up was restarted. One month after injection, 24 patients (80%) were symptom-free, 5 declared partial remissions, and one patient still had the same degree of pruritus ani. Five patients with partial remission underwent a second methylene blue injection, which provided complete relief in four. Therefore, the early response rate was 80% with single injection and 93.3% (28 of 30) with the rescue treatment. At six months, three recurrences were noted, indicating to a success rate of 83.3% (25 of 30). At 12 months after treatment, 23 patients (76.7%) were symptom free. This study has shown that intradermal methylene blue injection is a safe, simple, fast and efficient method of treating intractable idiopathic pruritus ani.

Transperineal Rectocele Repair with Polyglycolic Acid Mesh: A Case Series

PurposeThis study was designed to evaluate the outcome of transperineal rectocele repair using polyglycolic acid mesh.MethodsEighty-three consecutive females with predominant, symptomatic Stage II or Stage III rectocele underwent transperineal rectocele repair using polyglycolic acid (Soft PGA Felt®) mesh and finished their six-month follow-up. No additional interventions, including levatoroplasty or perineorraphy, were performed. The preoperative and postoperative symptom scores and stages of the posterior vaginal wall prolapse were recorded. The end points were reassessed at six months, postoperatively.ResultsPreoperatively, 39 patients had Stage II and 44 patients had Stage III rectocele. The mean total symptom score was 9.87 ± 1.93, which was reduced to 1.62 ± 0.59 postoperatively (P < 0.0001). Objective evaluation of anatomic repair revealed that 74 patients (89.2 percent) had anatomic cure. Surgical complications were seen in a total of seven patients (8.4 percent), including hemorrhage (3.6 percent) and wound infection (4.8 percent). Mesh erosion, mesh infection, or worsening of sexual function was not noted.ConclusionsTransperineal repair of rectocele with the polyglycolic acid mesh is an efficient therapy for patients with rectocele. It is highly successful in eliminating symptoms of obstructed defecation, and it is free of significant complications.

Keyhole Deformity: A Case Series

ObjectiveKeyhole deformity is frequently encountered after posterior internal sphincterotomy but may be observed after lateral internal sphincterotomy or in patients without any history of previous anal surgery. The aim of the present study is to emphasize the surgical significance of this entity and discuss the possible strategies in the treatment of the deformity.Material and MethodsPatients in whom keyhole deformity developed after surgical or conservative treatment applied for chronic anal fissure in our clinic and patients referred from other centers were recruited.ResultsNine-hundred twenty-six patients were treated for chronic anal fissure. A hundred of these patients directly underwent lateral internal sphincterotomy. The remaining 826 patients initially received conservative management, and 676 of them eventually underwent lateral internal sphincterotomy. In total, 15 patients were diagnosed to have significant keyhole deformity. Initially, all patients received conservative treatment for keyhole deformity, which was successful in two patients. Of the 13 patients in whom conservative management failed, nine underwent advancement flap reconstruction and the remaining four diamond flap reconstruction.ConclusionKeyhole deformity is occasionally seen as a late complication of chronic anal fissure and may be well tolerated by the patients without any well-defined symptoms. The treatment strategy is directed toward the degree of functional alteration.
