简介:AbstractObjectives:Timing of drain removal and its effects on complications after major pancreatectomy remain controversial. We designed this study to assess whether early drain removal after major pancreatectomy influences the incidence of complications in the patients with low risk of postoperative pancreatic fistula (POPF).Methods:This is a single-center randomized controlled trial (RCT). A total of 144 patients undergoing pancreaticoduodenectomy (PD) and distal pancreatectomy (DP) who met the criteria, including drain amylase on postoperative day (POD) 1 and 3 less than 5000 U/L and drain output within POD 3 less than 300 mL/d, were randomly assigned to early drain removal (POD 3) or standard drain removal (≥POD 5). The primary outcome was major complications (Clavien-Dindo grades 2-4), and the secondary outcome was POPF, reintervention treatment, readmission, and total medical expense within 3 months after surgery.Results:A total of 5 patients in early drain removal group had at least 1 major complications (grades 2-4), compared to 15 patients in standard drain removal group (P=.028). The incidence of grade B/C pancreatic fistula was not significantly different (2.8% vs 0%). Multivariate analysis demonstrated that early drain removal was an independent factor associated with a reduced risk of major complications (P=.039, odds ratio=0.314). Majority of major complications occurred in PD patients, and only very few cases occurred in DP patients. Stratified analysis showed that early drain removal significantly reduced the major complications only in the patients undergoing PD.Conclusion:This single-center RCT shows early drain removal on POD 3 is safe for both DP and PD patients, under our criteria. Early drain removal could reduce the incidence of major complications in patients undergoing PD.
简介:AbstractBackground:Defunctioning stoma is widely used to reduce anastomotic complications in rectal cancer surgery. However, the complications of stoma and stoma reversal surgery should not be underestimated. Furthermore, in some patients, stoma reversal failed. Here, we investigated the complications of defunctioning stoma surgery and subsequent reversal surgery and identify risk factors associated with the failure of getting stoma reversed.Methods:In total, 154 patients who simultaneously underwent low anterior resection and defunctioning stoma were reviewed. Patients were divided into two groups according to whether their stoma got reversed or not. The reasons that patients received defunctioning stoma and experienced stoma-related complications and the risk factors for failing to get stoma reversed were analysed.Results:The mean follow-up time was 47.54 (range 4.0-164.0) months. During follow-up, 19.5% of the patients suffered stoma-related long-term complications. Only 79 (51.3%) patients had their stomas reversed. The morbidity of complications after reversal surgery was 45.6%, and these mainly consisted of incision-related complications. Multivariate analyses showed that pre-treatment comorbidity (HR =3.17, 95% CI 1.27-7.96, P =0.014), postoperative TNM stage (HR =2.55, 95% CI 1.05-6.18, P =0.038), neoadjuvant therapy (HR =2.75, 95% CI 1.07-7.05, P =0.036), anastomosis-related complications (HR =4.52, 95% CI 1.81-11.29, P =0.001), and disease recurrence (HR =24.83, 95% CI 2.90-213.06, P =0.003) were significant independent risk factors for a defunctioning stoma to be permanent.Conclusions:Defunctioning stoma is an effective method to reduce symptomatic anastomotic leakage, but the stoma itself and its reversal procedure are associated with high morbidity of complications, and many defunctioning stomas eventually become permanent. Therefore, surgeons should carefully assess preoperatively and perform defunctioning stomas in very high risk patients. In addition, doctors should perform stoma reversal surgery more actively to prevent temporary stomas from becoming permanent.
