Limberg flap in management of pilonidal sinus disease: systematic review and a local experience.

OBJECTIVES: To review published evidence of Limberg flap (LF) use in pilonidal sinus disease (PSD). We also included our local experience of LF. METHODS: Medline and Embase database were searched for the words 'pilonidal, sinus, Limberg, flap'. Non-English articles and those not-related to our scope of search were omitted. We included a retrospective study of patients underwent LF in our district hospital. Data including length of hospital stay, post-operative complications and recurrence were collected. RESULTS: Literature review revealed 68 studies (22 case series, 35 comparative studies, nine RCTs and two meta-analyses). Recurrence rate was 0-7.4% in case series. Recurrence rate in comparative studies was 0-8.3%, compared to 4-37.7% for primary closure and 0-11% for Karydakis flap. RCTs showed that LF or its modification is superior to primary closure, with comparable results to Karydakis flap. About 26 patients included in the cohort study (16 male, average age 27 years). Six patients presented with recurrent disease. Post-operative length of hospital stay was four to seven days. Post-operative complication rate was 11.5% - [two partial wound dehiscence, one wound infection]. Recurrence rate was 7.7%. Average follow-up was 18 months. CONCLUSIONS: Limberg flap presents a safe and effective method that can be offered for patients with primary or recurrent PSD.

Bilateral adrenal haemorrhage with renal infarction after ChAdOx1 nCoV-19 AstraZeneca vaccination.

Vaccine-induced thrombotic thrombocytopaenia (VITT) is a rare syndrome associated with the ChAdOx1 nCoV-19 (AstraZeneca) vaccine. We detail a case of vaccine-induced thrombotic thrombocytopaenia in a 47-year-old female who was found to have bilateral adrenal haemorrhage, renal vein thrombosis, renal infarction and pulmonary embolism 13 days post-vaccination with ChAdOx1 nCoV-19.

SARS-CoV-2 detection by a clinical diagnostic RT-LAMP assay.

The ongoing pandemic of SARS-CoV-2 calls for rapid and cost-effective methods to accurately identify infected individuals. The vast majority of patient samples is assessed for viral RNA presence by RT-qPCR. Our biomedical research institute, in collaboration between partner hospitals and an accredited clinical diagnostic laboratory, established a diagnostic testing pipeline that has reported on more than 252,000 RT-qPCR results since its commencement at the beginning of April 2020. However, due to ongoing demand and competition for critical resources, alternative testing strategies were sought. In this work, we present a clinically-validated procedure for high-throughput SARS-CoV-2 detection by RT-LAMP in 25 minutes that is robust, reliable, repeatable, sensitive, specific, and inexpensive.

Utilisation of the falciform ligament pedicle flap as an alternative approach for the repair of a perforated gastric ulcer.

An 83-year-old woman presented to the emergency department with sudden onset of severe abdominal pain. She had a background of ulcerative colitis managed surgically at the age of 18 years with panproctocolectomy and permanent ileostomy. On admission, clinical assessment suggested a visceral perforation and an urgent CT scan demonstrated a perforated prepyloric ulcer. Emergency laparotomy was performed and confirmed a 3 cm perforated pre-pyloric ulcer. Repair of the defect was challenging due to the absence of omental fat to patch the perforation. A modification to the standard technique was therefore performed: the falciform ligament was mobilised and its free end used as a patch to repair the defect. The patient made a good postoperative recovery. This case report highlights an alternative operative technique for the treatment of perforated gastric/duodenal ulcers in patients who lack omentum, or when omentum cannot be used to cover perforated gastroduodenal ulcers.
