Background: Pilonidal sinus disease (PSD) is a common surgical disease. Multiple surgical methods exist in the literature, without clear consensus regarding which should be the first‐line treatment. Minimally invasive methods such as the Gips procedure are gaining popularity in recent years. The aim of our study was to assess recurrence rates following the Gips procedure and to determine whether using the same surgical approach during re‐operation is efficient and successful. Methods: This is a single‐center retrospective observational study of pediatric patients that underwent Gips procedure due to PSD between the years 2012–2022. Results: 565 pediatric patients underwent an elective surgery for PSD in the study period. Recurrence rate was 8.1% (n = 46). In all the patients with recurrence, re‐operation took place on average 9 months following the first surgery and using the same surgical method. Following the second surgery, only 8 patients (1%) had multiple recurrences. Conclusions: We found a relatively low recurrence rate in the pediatric population using the Gips method, and nearly 100% success rate following the second operation. Our findings set a new benchmark for pediatric recurrence following PSD operation, with clear recommendation to use the same method of surgery upon further recurrences as well.

Background: The timing of surgical intervention in Crohn's disease (CD) may depend on pre-operative optimization (PO) which includes different interventions to decrease the risk for unfavourable post-operative outcome. The objective of this study was to investigate the effect of multi-model PO on the post-operative outcome in CD. Method: This is a multicentre retrospective cohort study. The primary outcome was 30-day post-operative complications. Secondary outcomes were intra-abdominal septic complications, surgical site infection (SSI), re-operation, length of post-operative stay in a hospital and re-admission. PO included nutritional support, discontinuation of medications, pre-operative antibiotic course and thrombosis prophylaxis. Results: Two hundred and thirty-seven CD elective bowel resections were included. Mean age was 39.9 years SD 14.25, 144 (60.8 %) were female and 129 (54.4 %) had one or more types of medical treatment pre-operatively. Seventy-seven patients (32.5 %) optimized by at least nutritional support or change in pre-operative medications. PO patients were more likely to have penetrating disease phenotype ( p = 0.034), lower albumin ( p = 0.015) and haemoglobin ( p = 0.021) compared to the non-optimized. Multivariate analyses showed that treatment with anti-TNF alpha agents OR 2.058 CI [1.043-4.4.064] and low haemoglobin OR 0.741 CI [0.572-0.0.961] increased the risk of overall post-operative complications. Co-morbidity increased the risk of SSI OR 2.567 CI [1.182-5.576] while low haemoglobin was a risk factor for re-admission OR 0.613 CI [0.405-0.926]. Low pre-operative albumin correlated with longer stay in hospital. Conclusions: PO did not change post-operative outcome most likely due to selection bias. Anti-TNF alpha agents, low haemoglobin, low albumin and co-morbidity were associated with unfavourable outcome. [ABSTRACT FROM AUTHOR]
