Due to the absence of an extemporaneous biopsy, the resection margin was defined by a formula developed by the authors: 5 cm for patients under 5 years, 5 cm plus 1 cm per age from 6-10 years, and 5 cm plus 0.5 cm per age above 10 years. Post-operative mortality and complication rates were equally computed. Descriptive statistics were calculated for continuous variables. Discharge-to-Follow-up data were visualized using time-to-event curves.</p><p><strong>Results: </strong>Thirty-one patients aged 195 (interquartile range: 18-669) days were included in this study. Thirteen (58.93%) were from mining areas. The patients were surgically managed and follow-up for a year. 6.45% died in the 30-day post-operative period and 19.35% were lost to follow-up. The complaints were recorded from the fourth month following the surgery with most of the patients complained about fecal soiling (58.06%). The overall complaint rate was 80% (95%CI:56.20%-90.69%). The overall rate of incontinence was different compared to those with fecal soiling (p = 0.04). Although lacking statistical significance, the length of stay (LoS) post-surgery predicting an 9% increased incidence of complaints during the follow-up period (adjusted Hazard Ratio: 1.09, 95% CI:0.97-1.23).</p><p><strong>Conclusion: </strong>HD cause avertable morbidity in South Kivu. These data suggest that the long-term outcome in HD can be mitigated through appropriate surgical management during the operative and intervention aimed at optimizing the LoS.</p>","PeriodicalId":49229,"journal":{"name":"BMC Surgery","volume":"25 1","pages":"96"},"PeriodicalIF":1.6,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11899727/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143617806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
