Öğe Effect of triclosan-coated sutures on surgical site infections in pilonidal disease: Prospective randomized study(Springer, 2018) Arslan, Naciye Çiğdem; Atasoy, Gülsen; Altıntaş, Tansu; Terzi, CemPurpose The aim of this study is to investigate the effect of triclosan-coated sutures on surgical site infections after wide excision and primary closure for pilonidal disease. Methods One hundred seventy-seven patients were randomized into two groups: 91 in control and 86 in triclosan groups. In the control group, 1/0 monofilament polypropylene retention sutures, 3/0 polyglactin subcutaneous sutures, and 3/0 polypropylene skin sutures were used. In the triclosan group, 1/0 triclosan-coated monofilament polydioxanone, 3/0 triclosan-coated polyglactin, and 3/0 triclosan-coated monofilament polydioxanone were used. Postoperative care and follow-up was made by a surgeon according to Centers for Disease Control guideline. Surgical site infection rates between groups were compared. Secondary outcomes were seroma and wound dehiscence. Results Seroma was seen in 30 (16.9%) patients: 20 (23.3%) in the triclosan group and 10 (10.9%) in the control group (p= 0.030). Thirteen (7.3%) patients had superficial wound dehiscence: 5 (5.5%) patients in the control group and 10 (11.6%) patients in the triclosan group (p = 0.116). Overall surgical site infection (SSI) rate was 15.8% (n = 28): 19 (20.8%) patients in the control group and 9 (10.5%) patients in the triclosan group (p = 0 .0 44). Healing was observed on mean 17.8 +/- 6.7 days. Primary and secondary healing rates and time to healing were similar between groups. Conclusion Triclosan-coated sutures decreased surgical site infection rate but had no effect on time to healing in pilonidal disease. Seroma and wound dehiscence were more common in triclosan groups. Randomized trials are needed to clear the effect of triclosan-coated sutures on postoperative wound complications.Öğe Randomized controlled trial of 8 weeks' vs 12 weeks' interval between neoadjuvant chemoradiotherapy and surgery for locally advanced rectal cancer(Wiley, 2020) Terzi, Cem; Bingül, Meryem; Arslan, Naciye Çi?dem; Öztürk, Ersin; Canda, Aras Emre; Işık, Özgen; Yılmazlar, Tuncay; Obuz, Funda; Görken, İlknur Bilkay; Kurt, Meral A.; Ünlü, Mehtat Ş.; U?raş, Nesrin; Kanat, Özkan; Öztop, İlhanAim The aim was to compare the pathological complete response (pCR) rate at 8 compared to 12 weeks' interval between completion of neoadjuvant chemoradiotherapy (CRT) and surgery in patients with locally advanced rectal cancer. Method This was a randomized trial which included a total of 330 patients from two institutions. Patients with locally advanced (T3-4N0M0, TxN+M0) rectal cancer were randomized into 8- and 12-week interval groups. All the patients received long-course CRT (45 Gy in 1.8 Gy fractions and concomitant oral capecitabine or 5-fluorouracil infusion). Surgery was performed at either 8 or 12 weeks after CRT. The primary end-point was pCR. Secondary end-points were sphincter preservation, postoperative morbidity and mortality. Results Two-hundred and fifty-two patients (n = 125 in the 8-week group, n = 127 in the 12-week group) were included. Demographic and clinical characteristics were similar between groups. The overall pCR rate was 17.9% (n = 45): 12% (n = 15) in the 8-week group and 23.6% (n = 30) in the 12-week group (P = 0.021). Sphincter-preserving surgery was performed in 107 (85.6%) patients which was significantly higher than the 94 (74%) patients in the 12-week group (P = 0.016). Postoperative mortality was seen in three (1.2%) patients overall and was not different between groups (1.6% in 8 weeks vs 0.8% in 12 weeks, P = 0.494). Groups were similar in anastomotic leak (10.8% in 8 weeks vs 4.5% in 12 weeks, P = 0.088) and morbidity (30.4% in 8 weeks and 20.1% in 12 weeks, P = 0.083). Conclusion Extending the interval between CRT and surgery from 8 to 12 weeks resulted in a 2-fold increase in pCR rate without any difference in mortality and morbidity.Öğe Wound irrigation with chlorhexidine gluconate reduces surgical site infection in pilonidal disease: Single-blind prospective study(Mary Ann Liebert, 2020) Arslan, Naciye Çiğdem; Değirmenci, Ali Kadir; Özdenkaya, Yaşar; Terzi, CemBackground: The aim of this study was to determine whether incision irrigation with chlorhexidine gluconate (CHG) reduces surgical site infections (SSIs) in pilonidal disease surgery. Methods: Between 2013 and 2018, patients who underwent wide excision with primary closure for pilonidal disease were enrolled in this prospective observational multi-institutional cohort. The incision was irrigated with either saline or 0.05% CHG before skin closure. The infection risk of each patient was determined by the National Nosocomial Infection Surveillance System. Post-operative site care and follow-up were carried out according to the U.S. Centers for Disease Control and Prevention guideline by two surgeons blinded to the irrigation solution used. Surgical site infection rates in the saline and 0.05% CHG groups were compared. The secondary outcomes were seroma formation, incision dehiscence, and time to healing. Results: There were 129 patients in the control group and 138 patients in the CHG group. The mean age was 25.1 +/- 5.4, and 225 patients (84.3%) were male. Surgical site infection was seen in 35 patients (13.1%): 26 (20.2%) in the control group and 9 (6.5%) in the CHG group (p = 0.001). There were no differences in seroma formation (n = 12; 9.3% in the control vs n = 12; 8.7% in the CHG group; p = 0.515) or incision dehiscence (n = 9; 7% in the control vs n = 9; 6.5% in the CHG group; p = 0.537). The primary healing rate was higher in the CHG group (n = 130; 94.2%) than in the control group (n = 104; 80.6%). Time to healing was 20.5 +/- 7.8 days in the control group and 16 +/- 4.3 days in the CHG group (p < 0.001). Conclusion: Intra-operative incision irrigation with CHG decreased the SSI rate and time to healing in pilonidal disease surgery. Further randomized trials should focus on specific irrigation methods and procedures to build a consensus on the effect of incision irrigation on SSIs.
