Management of acute appendicitis during the COVID-19 pandemic: a retrospective cohort study.

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) pandemic profoundly impacted delivery of health care. South Western Sydney Local Health District (SWSLHD) experienced some of the highest cases, admissions and deaths during the Delta and Omicron waves in New South Wales. This study aims to determine the impact of the pandemic on emergency surgery services for adults presenting with acute appendicitis. METHODS: A retrospective review of patient records was performed of adults presenting with acute appendicitis between 1st March 2021 and 31st March 2022, which was compared to a pre-COVID control period of the same dates in 2019-2020. Patients managed operatively or conservatively were included. RESULTS: 1556 patients were included in the operative arm; 723 and 833 respectively in the study and control groups, which were comparable at baseline. 1.66% were COVID positive. During the pandemic, patients were significantly more likely to be investigated with computered tomography (CT) scan (p ≤ 0.001), present with complicated appendicitis (p = 0.03), and require caecectomy (p = 0.005). They had higher American Society of Anaesthesiology (ASA) scores (p = 0.001) and significantly lower negative appendectomy rates (p = 0.001). Fifty-two patients were included in the conservative arm; 29 and 23 respectively in the pandemic and control groups. Patients were comparable at baseline. There were two COVID positive patients. During the pandemic, there was a significant reduction in complications (p = 0.033), readmissions (0.044) and interval appendicectomy (p = 0.0044). CONCLUSION: We identified higher rates of complicated appendicitis, caecectomies and greater reliance on CT imaging preoperatively during the pandemic in SWSLHD.

Functional restoration after early tendon transfer in high radial nerve paralysis.

We assessed the effect of an early transfer of pronator teres to extensor carpi radialis brevis on hand function in patients with high radial nerve paralysis. Power grip and precision grip were measured preoperatively and postoperatively using a dynamometer. Fifteen patients were operated on, of which ten could be assessed at the end of 6 months. At 6 months after surgery, there was a median increase of 48% in power grip, 162% in tip pinch, 90% in key pinch and 98% in palmar pinch. Decreased palmar flexion was seen in four patients. Fraying of the periosteal extension and rupture of sutures at the junction site were each seen in one patient, leading to unsatisfactory results. Early tendon transfer quickly restored efficient grip while awaiting reinnervation of wrist extensors, avoiding the need for prolonged external splintage.
