Abstract

Delayed healing of the extraction socket is not uncommon when tooth extraction is performed on patients taking prednisolone. This study aimed to identify specific dosage of prednisolone and factors associated with delayed healing of the extraction socket in patients taking prednisolone. This single-center retrospective study included 80 patients who underwent tooth extraction under local anesthesia and were taking prednisolone orally. Patients were divided into the nondelayed healing group (n = 50) and delayed healing group (n = 30), and their background and dosage of prednisolone were compared. The dosage of prednisolone was significantly higher in the delayed healing group than in the nondelayed healing group. A receiver operating characteristics curve analysis resulted in moderate accuracy when the cutoff value was set at 8.0, with 67% sensitivity, 76% specificity, and 0.765 area under the curve. The multivariate logistic regression analysis revealed that prednisolone dosage >8.0 mg/day (odds ratio [OR], 10.8; 95% confidence interval [CI], 2.79–41.6) and osteosclerotic changes beyond the alveolar bone around the tooth to be extracted (OR, 10.3; 95% CI, 2.81–37.8) in X-ray imaging had significant effects on delayed healing. The results of this study suggested that delayed healing following tooth extractions in patients taking prednisolone was related to a dosage of 8.0 mg/day or higher and osteosclerotic changes.

Abstract

Background: Anastomotic leakage (AL) after colorectal surgery is associated with insufficient vascular perfusion of the anastomotic ends. This study aimed to evaluate the effect of high vs. low ligation of the ileocolic artery and inferior mesenteric artery, respectively, on the vascular perfusion of the bowel stumps during ileocecal resection (ICR) and anterior rectal resection (AR). Methods: We retrospectively evaluated patients who underwent ICR or AR between 2016 and 2020. Real-time indocyanine green fluorescence angiography was performed to measure the fluorescence time (FT) as a marker of the blood flow in the proximal and distal stumps before anastomosis. Results: Thirty-four patients with lower right-sided colon cancer underwent laparoscopic ICR. Forty-one patients with rectosigmoid colon or rectal cancer underwent robotic high AR (HAR) (n = 8), robotic low AR (LAR) (n = 6), laparoscopic HAR (n = 8), or laparoscopic LAR (n = 19). The FT was similar in the ileal and ascending colon stumps (p = 1.000) and did not differ significantly between high vs. low ligation of the ileocolic artery (p = 0.934). The FT was similar in the sigmoid colon and rectal stumps (p = 0.642), but high inferior mesenteric artery ligation significantly prolonged FT in the sigmoid colon during AR compared with low ligation (p = 0.004), indicating that the high ligation approach caused significant hypoperfusion compared with low ligation. The AL rate was similar after low vs. high ligation. Conclusions: Low vascular perfusion of the bowel stumps may not be an absolute risk factor for AL. High inferior mesenteric artery ligation could induce sigmoid colon stump hypoperfusion during anterior rectal resection.

Abstract

Background and Aims: Endoscopic papillary balloon dilation (EPBD), a low-risk procedure for bleeding, has been suggested as an alternative to endoscopic sphincterotomy for papillary dilatation in patients undergoing endoscopic stone removal who are at a higher risk of bleeding. Several guidelines recommend that combination of two antiplatelet agents should be reduced to single antiplatelet therapy when endoscopic sphincterotomy is performed. However, there is no evidence that EPBD affects the risk of bleeding in patients receiving a combination of two antiplatelet agents; thus, we aimed to explore this problem., Methods: We included 31 patients who underwent EPBD for common bile duct stones at our hospital from May 2014 to August 2022 and received either a combination of two antiplatelet agents or single antiplatelet therapy prior to the procedure. The group receiving a combination of two antiplatelet agents included patients who underwent EPBT without antiplatelet therapy withdrawal or with a shorter withdrawal period than those recommended by the guidelines., Results: In the group that received a combination of two antiplatelet agents, one of the two antiplatelet agents used was thienopyridine. No bleeding was observed after EPBD in this study. We did not find any significant between-group differences in hemoglobin levels and rate of post-endoscopic retrograde cholangiopancreatography pancreatitis., Conclusions: In patients treated with a combination of two antiplatelet agents, EPBD could be safely performed without bleeding. Therefore, future prospective studies are warranted.
