PURPOSE: Traditional longitudinal incision for carotid endarterectomy (CEA) can be painful, aesthetically displeasing, and associated with a high incidence of cranial nerve injury (CNI). This study describes the outcomes of CEA performed through small (<5 cm long), transversely oriented incisions located directly over the carotid bifurcation, as identified by color-enhanced duplex ultrasound. MATERIALS AND METHODS: Patient demographics and operative data were collected retrospectively from an in-house database of consecutive vascular patients undergoing CEA with a small transversely oriented incision for both symptomatic and asymptomatic carotid artery stenoses. RESULTS: A total of 52 consecutive patients underwent CEA between 2012 and 2016 (median age, 73.5 years; interquartile range, 67-80.3; male/female ratio, 40:12). CEA was performed under regional/local anesthesia (LA) in 48 (92.3%) patients, with 4 (7.7%) being performed under general anesthesia. One patient under LA experienced intraoperative neurological dysfunction intraoperatively (manifesting as an inability to count out loud) that resolved with insertion of shunt. One patient experienced a transient neurological event (expressive dysphasia) within the immediate postoperative period, which resolved within 6 hours. No in-hospital death or perioperative major adverse cardiovascular events were noted. Follow-up data were available for a median period of 3.1 years and for all patients. Three patients experienced strokes following discharge (2 strokes contralateral to the operated side and 1 transient ischemic attack ipsilateral to the operated side). No persistent CNIs nor bleeding complications necessitating re-exploration were reported. CONCLUSION: Small, transversely orientated incisions, hidden within a neck skin crease can be safely performed in the majority of patients undergoing CEA.

INTRODUCTION: Timely administration of prophylactic antibiotics within 60 minutes before surgical incision is important for reducing surgical site infections. This quality improvement initiative aimed to work towards achieving 100% compliance with perioperative antibiotic administration. METHODS: We examined the workflow in our Anaesthesia Information Management System (AIMS) and proposed interventions using cause-and-effect analysis of anonymised anaesthetic records from eligible surgical cases extracted from AIMS. This ultimately led to the implementation of an antibiotic pop-up reminder. The overall process was done in a few small plan-do-study-act cycles involving raising awareness, education and reorganisation of AIMS before implementation of the antibiotic pop-up reminder. Data analysis took place from August 2014 to September 2016. Compliance was defined as documented antibiotic administration within 60 minutes before surgical incision, or as documented reason for omission. RESULTS: The median monthly compliance rate, for 33,038 cases before and 28,315 cases after the reminder was implemented, increased from 67.0% at baseline to 94.5%. This increase was consistent and sustained for a year despite frequent personnel turnover. Documentation of antibiotic administration also improved from 81.7% to 99.3%, allowing us to identify and address novel problems that were initially not apparent, and resulting in several department recommendations. These included administering antibiotics later for cases with predicted longer-than-expected preparation times and bringing forward antibiotic administration in lower-segment Caesarean sections. CONCLUSION The use of information technology and implementation of an antibiotic pop-up reminder on AIMS streamlined our work processes and brought us closer to achieving 100% on-time compliance with perioperative antibiotic administration.

The concept of theranostics, where individual patient-level biological information is used to choose the optimal therapy for that individual, has become more popular in the modern era of ‘personalised’ medicine. With the growth of theranostics, nuclear medicine as a specialty is uniquely poised to grow along with the ever-increasing number of concepts combining imaging and therapy. This special report summarises the status and growth of Theranostic Nuclear Medicine in Singapore.We will cover our experience with the use of radioiodine, radioiodinated metaiodobenzylguanidine, peptide receptor radionuclide therapy, prostate specific membrane antigen radioligand therapy, radium-223 and yttrium-90 selective internal radiation therapy.We also include a section on our radiopharmacy laboratory, crucial to our implementation of theranostic principles. Radionuclide theranostics has seen tremendous growth and we hope to be able to grow alongside to continue to serve the patients in Singapore and in the region.
