ABSTRACT
Abstract Objective Several techniques are used to repair the anal sphincter following injury. The aim of the present study is to comprehensively analyze the short- and long-term outcomes of overlap repair following anal sphincter injury. Methods A search was conducted in the PubMed, Medline, Embase, Scopus and Google Scholar databases between January 2000 and January 2020. Studies that described the outcomes that are specific to overlap sphincter repair for fecal incontinence with a minimum follow-up period of one year were selected. Results A total of 22 studies described the outcomes of overlap sphincter repair. However, 14 studies included other surgical techniques in addition to overlap repair, and were excluded from the analysis. Finally, data from 8 studies including 429 repairs were analyzed. All studies used at least one objective instrument; however, there was significant heterogeneity among them. Most patients were female (n=407; 94.87%) and the mean age of the included individuals was 44.6 years. The majority of the procedures were performed due to obstetric injuries (n=384; 89.51%). The eight included studies described long-term outcomes, and seven of them demonstrated statistically significant improvements regarding the continence; one study described poor outcomes in terms of overall continence. The long-term scores were significantly better compared with the preoperative scores. However, compared with the shortterm scores, a statistically significant deterioration was noted in the long-term. Conclusion The majority of the studies described good long-term outcomes in terms of anal continence after overlap sphincter repair. However, further studies are needed
Resumo Objetivo Diversas técnicas são usadas no reparo do esfíncter anal após lesões. O objetivo deste estudo é fazer uma análise completa dos desfechos nos curto e longo prazos do reparo por sobreposição após lesão do esfíncter anal. Métodos Realizou-se uma busca nas bases de dados PubMed, Medline, Embase, Scopus e Google Scholar entre janeiro de 2000 e janeiro de 2020. Estudos que descreviam desfechos específicos do reparo de esfíncter por sobreposição para incontinência fecal, com um mínimo de 1 ano de seguimento, foram selecionados. Resultados No total, 22 estudos descreviam os desfechos do reparo de esfíncter por sobreposição. No entanto, 14 estudos incluíam outras técnicas cirúrgicas além do reparo por sobreposição, e foram excluídos da análise. Por fim, dados de 8 estudos que incluíam 429 reparos foram analisados. Todos os estudos usaram pelo menos um instrumento objetivo, mas havia uma heterogeneidade significativa entre eles. A maioria dos pacientes era do sexo feminino (n=407; 94,87%), e a idade média dos indivíduos incluídos foi de 44,6 anos. A maioria das cirurgias foi realizada devido a lesões obstétricas (n=384; 89,51%). Os oito estudos incluídos descreveram os desfechos no longo prazo, e sete deles demonstraram melhoras estatisticamente significativas com relação à continência; um estudo descreveu resultados ruins em termos gerais com relação à continência. As pontuações no longo prazo foram significativamente melhores em comparação com as pontuações no pré-operatório. No entanto, em comparação com as pontuações no curto prazo, percebeu-se uma piora estatisticamente significativa no longo prazo. Conclusão A maioria dos estudos descrevia bons resultados no longo prazo em termos de continência anal depois do reparo do esfíncter por sobreposição. Entretanto mais estudos são necessários para que se identifiquem os fatores associados aos desfechos ruins para auxiliar na seleção de pacientes para o reparo por sobreposição.

Fistula in ano is a common perianal disease of the mankind. It is secondary to mainly cryptoglandular infections & abscess. Persistence of chronic infection will lead to fistula formation.1 Management of high-level fistulas is complicated due to incontinence, which is troublesome; hence, many procedures have been tried by many surgeons, but without any supremacy over others. Immediate reconstruction of divided sphincter muscle will give good result.2 We have done fistulectomy & repair of the external anal sphincter & followed for the last two decades with no incontinence & minimal recurrences.METHODS192 cases of fistula in ano for the last 20 years operated by a single surgeon (1st author) were studied & were followed up to now. The differences, in the selection of cases, surgical skill & post-operative management are excluded in the study by including cases done by a single surgeon (first author) only. 136 males & 56 females were operated. Intersphincteric 45.8%, trans-sphincteric 49%, high level fistulas 5.2%, trans-sphincteric & high fistulas with considerable external sphincter loss (54 cases) were repaired with 1–0 Vicryl. Fistula in ano is associated with haemorrhoids in 24/192 & ano rectal abscess (20/192). Fistulotomy done in 16/192, simple & subcutaneous tracts - fistulectomy done in 65%. Curetting of the high tracts done in 16/192.RESULTSMales are predominantly affected 70.8%. This is more common in 3rd, 4th & 5th decades (80.1%). Single external opening was seen in (90%). Posterior & lateral fistula tracts are more commonly seen in (89.6%). Non-specific pyogenic infective pathology is seen 99%. Recurrences- 6/192. Time taken to heal is 3–6 weeks. Incontinence is not seen in any case. No recurrence or incontinence seen in primary sphincter repair of 54 cases.CONCLUSIONSPrimary sphincter repair is simple & best procedure with minimal or no recurrence & decreases the healing time. It is more suitable & advised in fistulas with considerable external sphincter loss.
ABSTRACT
PURPOSE: This study was designed to evaluate the outcome of anterior sphincter repair and factors influencing the outcome in patients with obstetric fecal incontinence. METHODS: Thirty-three patients undergoing sphincter repair for obstetric fecal incontinence were prospectively evaluated. Preoperatively, standardized interviews and physiologic studies were performed. The severity of incontinence was graded according to the Parks' classification. Patients' satisfaction was classified as excellent, good, fair, and no improvement. An anterior overlapping sphincteroplasty was performed with or without levatorplasty. Interviews and manometry were repeated three months after the operation. Four years after the operation, the severities of incontinence and patients' satisfaction were reevaluated. RESULTS: Preoperatively, all patients showed high-grade incontinence (grade 3 or 4). Three months after the operation, 28 patients (84.8%) had successfully recovered continence (incontinence grade 1 or 2), and 25 of those patients (75.8%) replied with satisfaction (excellent or good). The maximal average squeeze pressure (MASP) and the high-pressure zone (HPZ) length, but not the maximal average resting pressure (MARP), had significantly increased in patients with successfully recovered continence. At the 4-year follow ups, the outcomes were significantly worse than thase at 3 months, but 24 patients (72.7%) still maintained good outcome, and 25 patients (66.7%) still replied with satisfaction that was not significantly worse than that at 3 months. Patients with a young age (<45 years), a shorter duration of incontinence (<10 years), a larger increase in MASP or MASP at 3 months after the operation, no pudendal neuropathy, and a good result at 3 months were more likely to maintain low-grade incontinence. The addition of levatorplasty and an increase in the HPZ length at 3 months did not affect the outcome. CONCLUSIONS: At the 4-year follow-ups, the outcomes had significantly deteriorated, but patients' satisfaction had not. Age, the duration of incontinence, a postoperative increment in MASP or MASP, pudendal neuropathy, and a short-term good outcome were closely related to the long-term outcome.

PURPOSE: We designed this study to evaluate efficacy of sphincter repair and factors influencing in patients with postobstetric fecal incontinence. METHODS: Twenty-one patients (mean age 42 years; range 23~67) undergoing sphincter repair for postobstetric fecal incontinence (mean duration 12 years; range 6 months~46 years) were evaluated prospectively. Preoperatively, standardized interviews, anorectal manometry and measurement of pudendal nerve terminal motor latency (PNTML) were performed. Incontinence was graded according to the Parks' classification: Grade 1 - continence to stool and flatus; Grade 2 - incontinent to flatus, some urgency to stool present but no incontinence; Grade 3 - incontinent to liquid stool; Grade 4 - incontinent to formed stool. Sphincter repair methods were overlap repair of external anal sphincter (EAS) in 4 patients, overlap repair of EAS with anterior levatorplasty in 15 patients, and overlap repair of EAS with anterior levatorplasty and postanal repair in 2 patients. Anorectal manometry at 3 months, and interviews at 3 months and 6 months after sphincter repair were performed again. Patients' satisfaction was classified as excellent, good, fair, and no improvement. RESULTS: Difficulty in first delivery was noticed in 18 patients and history of previous sphincter repair was noticed in 5 patients. Preoperatively, most patients showed high grade incontinence (grade 3 in 13 and grade 4 in 8 patients). After sphincter repair, 18 patients (85.7%) became grade 1 or 2, and 16 patients (76.2%) replied their functional satisfaction excellent or good. There were no difference between the results at 3 months and 6 months. Poor functional outcome was in 2 of 3 patients with bilaterally prolonged preoperative PNTML. Short duration of incontinence and young age at the time of repair favored good results. Previous sphincter repair did not influence the outcome. Postoperatively both anal pressure and high pressure zone length were significantly increased in patients with improved continence Postoperative complications were wound infection in 2 patients and necrosis at the apex of the advancement skin flap in 1 case but these did not influence the outcome. CONCLUSIONS: Most postobstetric fecal incontinence can be successfully treated with sphincter repair. Excellent results are expected when the duration of incontinence is short and the patients are young. Pudendal neuropathy seemed to be related to poor outcome.
