Effective sealing of biliary and pancreatic fistulas with a novel biodegradable polyurethane-based tissue sealant patch

The latest guidelines from the Enhanced Recovery After Surgery (ERAS®) Society stated that early drain removal after pancreatoduodenectomy (PD) is beneficial in decreasing complications including postoperative pancreatic fistulas (POPFs). This study aimed to ascertain the actual benefits of early drain removal after PD. The data of 450 patients who underwent PD between 2018 and 2020 were retrospectively reviewed. The surgical outcomes were compared between patients whose drains were removed within 3 postoperative days (early removal group) and after 5 days (late removal group). Logistic regression analysis was performed to identify the risk factors for clinically relevant POPFs (CR-POPFs). Among the patients with drain fluid amylase < 5000 IU on the first postoperative day, the early removal group had fewer complications and shorter hospital stays than the late removal group (30.9% vs. 54.5%, p < 0.001; 9.8 vs. 12.5 days, p = 0.030, respectively). The incidences of specific complications including CR-POPFs were comparable between the two groups. Risk factor analysis showed that early drain removal did not increase CR-POPFs (p = 0.163). Although early drain removal has not been identified as apparently beneficial, this study showed that it may contribute to an early return to normal life without increasing complications.

Pancreatic Fistulas

AbstractPostoperative pancreatic fistulas are complex, challenging problems that often take weeks, months, or longer to resolve. Multiple interventions may be required to achieve a successful outcome. As such, resolution typically involves a multidisciplinary approach by a team whose skills include abdominal imaging, specialized surgery, advanced endoscopy, and interventional radiology. Intensive resources and time are often required, which impacts both patients and their caregivers. While treatment(s) continue to improve, a primary goal of research efforts in this area is the prevention of this significant source of postoperative morbidity, mortality, and economic strain.

Background/Purpose: This study aimed to evaluate the feasibility and safety of a novel pancreaticogastrostomy technique for diminishing pancreatic fistulas after pancreaticoduodenectomy using gastric wrapping of the pancreatic stump with a twin square-shaped horizontal mattress and a suture fixing the main pancreatic duct to the gastric mucosa anastomosis [twin square wrapping (TSW) method]. Methods: Fifty-three patients undergoing pancreaticogastrostomy after pancreaticoduodenectomy were included in the study and chronologically divided into a conventional group (n = 32) and a TSW group (n = 21). The perioperative factors and the postoperative outcomes were retrospectively analyzed. Results: The operating time for the pancreatic anastomosis, the total operating time, and the blood loss volume in the TSW group were lower than in the conventional group, but without a statistically significant difference. The TSW group had a significantly lower postoperative white blood cell count and C-reactive protein level, with a reduced intra-abdominal fluid accumulation as assessed by computed tomography on postoperative day 7, had a lower incidence of postoperative complications and pancreatic fistulas, and achieved a shorter duration of drain placement and shorter postoperative hospital stays as compared to the conventional group. Conclusions: The TSW technique should be considered for reducing pancreatic fistulas by diminishing the postoperative inflammatory response and improving patient outcomes without increasing the operating time.

Objective. Gelatin-thrombin matrix (GTM) tissue sealant use was previously identified as an independent predictor of pelvic infection following hysterectomies. We aim to elucidate contributing factors by assessing influence of GTM on bacterial colony formation and characterizing bacteria present at the vaginal cuff.Methods.Escherichia coliwas incubated in phosphate-buffered saline (PBS) and pelvic washings with and without GTM to assess influence on colony formation. Pelvic washings of the vaginal cuff were collected from hysterectomies occurring from June through October 2015.In vitrotechniques, 16S rRNA gene qPCR, and 16S amplicon sequencing were performed with washings to characterize bacteria at the vaginal cuff.Results. Mean bacterial colony formation in PBS was greater forE. coliincubated in the presence of GTM (1.48 × 107 CFU/mL) versus without (9.95 × 105 CFU/mL) following 20-hour incubation (p=0.001). Out of 61 pelvic washings samples, 3 were culture positive (≥5000 CFU/mL) withEnterococcus faecalis.Conclusion.In vitroexperiments support a facilitating role of GTM on colony formation ofE. coliin PBS. However, given the negative results of surgical site washings following adequate disinfection, the role of GTM in promoting posthysterectomy pelvic infections may be limited. Analysis of pelvic washings revealed presence ofE. faecalis, but results were inconclusive. Further studies are recommended.
