Background This study aimed to characterize the time‐dependent relationship between serum C‐reactive protein (CRP) and anastomotic integrity in the early post‐operative period and to develop a systematic use of CRP and computed tomography. Methods Patients aged 18 years or over who had the formation of a left‐sided colonic or a colorectal anastomosis, in Royal Sussex County Hospital, were included. The post‐operative day (POD) CRP cut‐off values were calculated according to receiver operating characteristic analysis to evaluate the sensitivities and specificities of the proposed cut‐off parameters. Results A total of 125 left‐sided colonic and colorectal anastomoses were recruited and analysed. When comparing to POD1 CRP cut‐off, the calculated CRP ratio cut‐off values of all the rest of PODs (2–5) were highly significant in the laparoscopic group and the overall group (P < 0.001). This statistically significant ratio was also demonstrated in the open group at POD2 (P < 0.0001). Conclusion CRP and CRP ratios cut‐off values were sensitive to detect an anastomotic leak in the early post‐operative period. The cut‐off values could facilitate the development of systematic use of CRP and computed tomography.

We describe a case of paediatric orbital cellulitis with subperiosteal abscess following blunt facial trauma. Clinical features of orbital cellulitis developed on day 1 post-trauma. A subperiosteal collection subsequently formed lateral to the globe, causing significant ocular compromise. Surgical drainage and sinus washout were performed via external incisions, with satisfactory outcome. This case highlights how trauma may represent a non-sinogenic aggravating factor in orbital cellulitis. We describe how a subperiosteal abscess may vary depending on its aetiology, and how the surgical approach can be modified to locate and drain a laterally sited subperiosteal abscess.

Slingshots or hand catapults, historically used as a military or hunting weapon, are common toys among children and young teenagers. Their use can be dangerous as a strike to the eye or orbit can result in significant injuries including blindness. We describe a rare case of a sino-orbital foreign body caused by a slingshot injury in a young boy. The case was managed by a multidisciplinary team involving ear, nose and throat, ophthalmology and paediatrics, and the foreign body of a metal ball bearing was removed using an endoscopic transnasal approach. Although the patient made a good recovery, the case highlights the danger of slingshot devices misused by children.

Oesophageal squamous cell papilloma is a very rare entity with a limited number of reports in the literature. The exact aetiology is uncertain, and it commonly overlaps with gastro-oesophageal reflux. Human papilloma virus (HPV) is deemed responsible for some cases. Although incidental discovery during upper gastrointestinal endoscopy for other reasons is the commonest presentation, symptomatic cases do occur. Endoscopic excision is the standard treatment. We report a case of HPV-positive squamous papilloma of the upper oesophagus, presenting with lateralising throat pain and diagnosed with office transnasal oesophagoscopy. We also discuss features of HPV-positive oesophageal squamous papilloma and the role of transnasal oesophagoscopy as a recent diagnostic modality of increasing popularity.

Aim This case highlights the need for appropriate training when adopting new techniques, even for relatively simple procedures. Method we report a rare complication of the innovative COVID-19 nasopharyngeal swab which is a new skill for many healthcare professionals and frequently performed with little or no training. Results We describe a case of iatrogenic epistaxis after a diagnostic nasopharyngeal swab was taken during the COVID-19 pandemic. The epistaxis was significant, causing haemodynamic and respiratory compromise. In a frail patient who is susceptible to epistaxis, the potenial for further harm is significant. After initially presenting with shortness of breath, this patient (who had no previous nasal pathology) underwent routine naso- and oro- pharyngeal swabbing to test for COVID-19. He felt immediate discomfort in his nasopharynx and epistaxis ensued. The bleeding persisted for several hours; bilateral anterior and posterior nasal packing was required to eventually cease the bleed. He was compromised with a falling haemoglobin, and aspiration of blood compounded his shortness of breath. Conclusions Epistaxis is a potentially serious side effect of nasopharyngeal swabbing; a procedural skill dramatically increasing in prevalence during the COVID-19 pandemic. We advocate for formal training of this procedure for all healthcare staff required to undertake it. Presenting such a case report can help us in understanding the complications of this procedure, and better thus inform the patient consenting process.

We present a case of pinna pressure necrosis secondary to the use of ear magnetic discs, used in the management of auricular haematoma. A man in his 20s sustained a left auricular haematoma while wrestling. His coach aspirated the haematoma and advised the use of commercially available compression magnets on either side of the pinna to prevent haematoma reaccumulation. 5 days later, he presented to accident and emergency with left ear pain and swelling. Perichondritis was evident on examination and the compression magnets were removed to reveal significant pressure necrosis of the pinna. The skin underlying the placement of magnets (both anteriorly and posteriorly) was black and necrosed, with erosion of the underlying cartilage. In addition to this, the haematoma had reaccumulated in the surrounding pinna. The haematoma was drained via an incision, and pressure dressing applied with dental rolls. The patient was given a course of oral antibiotics to manage the perichondritis. He was reviewed regularly in the ear, nose and throat emergency clinic to monitor wound healing. 3 months later, he was reviewed in the otology clinic; there was persistent helical rim deformity, and delayed cartilage augmentation was advised.This case highlights the importance of prompt and effective management of auricular haematoma, to prevent long-term deformity. Commercially available pinna magnets for auricular haematoma should be used with caution, and patients should be counselled as such.
