Does CT Reduce the Rate of Negative Laparoscopies for Acute Appendicitis? A Single-Center Retrospective Study.

In surgical practice, surgeons request CT scans to rule out acute appendicitis, even in young patients. We aimed to assess the feasibility of using a CT scan to reduce the rate of negative laparoscopies in patients younger than 40 with equivocal signs of acute appendicitis. Therefore, we conducted a retrospective observational study on the patients admitted with a provisional diagnosis of acute appendicitis. Patients younger than 40 and with the Alvarado score between 3 and 6 were included. These were divided into two groups: those who had or did not have a CT scan. Each group was further subdivided into patients that had a laparoscopy and those that did not. Out of 204 patients included in the study, 16% were included in the CT group, and 84% in the non-CT group. 71.9% of the patients that underwent a CT scan had appendicitis and underwent an appendectomy. Five patients with a normal CT scan had appendectomy due to persistent signs of acute appendicitis. The histopathology of the 23 patients with positive CT was positive, and 3 of the 5 patients with negative CT that underwent appendectomy had positive histology results. The negative appendectomy rate for patients that had preoperative CT is 7.14% compared to 32.4% in patients without preoperative CT. The rate of negative laparoscopy in patients younger than 40 years old that undergo preoperative CT is significantly lower with a p-value of .00667.

Urinary catheters in the emergency department: a prospective audit to improve quality control.

INTRODUCTION: The best way to prevent urinary catheter related complications is to avoid unnecessary insertions of catheters and removing the catheters when they are no longer necessary. Previous studies have shown 47% documentation rate of urinary catheter (UC) insertion in the Emergency Department (ED) and have found one-sixth of patients in the ED have no indication for UC insertion. The aim of this audit was to record the indications and documentation of UC insertion in the ED and to propose an intervention to improve the quality of these processes. MATERIAL AND METHODS: A prospective audit was conducted in a tertiary university teaching hospital in Ireland over an eight-week period. A week-long intervention was conducted in the ED to educate staff, an ED doctor was involved in directly communicating this to the staff thereafter and concise labels were introduced to document relevant details about each UC insertion. The pre-intervention and post-intervention data was compared using Chi-Square tests. RESULTS: A total of 103 (50 pre-intervention and 53 post-intervention) consecutive age and gender matched patients were recruited in the audit over 8 weeks. The documentation for UC insertion improved by 22% (8% to 30%, (p <0.001, chi-square) while the non-indication for UC insertion reduced by 6% (36% to 30%, p = 0.53, chi-square). CONCLUSIONS: A simple intervention achieved significantly improved documentation of UC insertion and a trend toward increased appropriateness of UC insertion. This audit serves as an example to improve quality control around UC insertion which could be adopted in other institutions.

Postoperative Outcomes and Patient's Satisfaction after Hybrid TIPP with UHS and TEP Repair for Inguinal Hernias: A Single-Centre Retrospective Comparative Study.

Background: Transabdominal Preperitoneal (TAPP) and Totally Extraperitoneal (TEP) inguinal hernia repairs are largely acclaimed for their lower risk of chronic postoperative pain and acceptable recurrence rates. However, hybrid/combined open procedures are still a reliable option among surgeons. Our aim is to compare the outcomes and patients satisfaction of hybrid TIPP (hTIPP) procedure using the Ultrapro Hernia System with laparoscopic pre-peritoneal mesh repair approaches (TEP) to assess its safety and effectiveness. Patients and Methods: The study design is a single center, retrospective comparative study on 90 patients who had hTIPP and TEP inguinal hernia repair in the NAAS General Hospital, over a four-year period (2013-2017). Results: Unplanned postoperative hospital admission was comparable both groups, the figures were 3 patients for hTIPP and 3 patients for TEP. There was no statistically significant difference in the immediate, early and late postoperative pain and complications in both groups. The recurrence rate was nil in hTIPP group compared to one recurrent case in TEP. There is no statistical difference in the five outcomes of the PROM questionnaire and satisfaction rate between hTIPP and TEP. Conclusions: There is no significant difference between hTIPP and TEP in terms of postoperative outcomes and patient satisfaction. hTIPP approach is a safe and feasible alternative to TEP.

Intraoperative removal of a knotted Swan-Ganz catheter during lung transplantation.

We describe the case of a 52-year-old man with end-stage emphysema who underwent a right-sided lung transplantation. During preoperative monitoring an apparently non-functioning Swan-Ganz catheter could not be removed through the insertion site - right internal jugular vein. Another Swan-Ganz catheter was successfully installed through the left internal jugular vein, pulmonary artery pressures could be recorded and the transplant was performed uneventfully. Then, the first catheter was inspected and superior vena cava palpation surprisingly revealed a knot at approximately 25 cm. The catheter was pushed to the azygous vein, proximal and distal controls were obtained and a venotomy was performed. The knotted side was sectioned and removed, while the remaining catheter was removed through the insertion site. Despite being rare, knotted intravascular devices have been increasingly reported. Removal with interventional radiology techniques can be accomplished in most instances, nevertheless, complex knots or knots fixed into cardiac structures require open removal. Since in our case the knot was detected intraoperatively, it was readily removed through the azygous vein. To the best of our knowledge, this is the first report to describe such a route of removal.
