AbstarctThe use of diathermy to achieve haemostasis after tonsillectomy remains controversial. We have reviewed the English language literature, and found no convincing evidence that diathermy is any more likely to cause post-operative haemorrhage than the use of ligatures. The results of a prospective, randomized study of 1036 consecutive tonsillectomies are presented. No significant difference was found in post-operative haemorrhage rates when either diathermy or ligatures were used. Diathermy was found to reduce operating time compared to ligatures. The possibilities for day-case tonsillectomy are discussed.
A case of acute isolated sphenoid sinusitis is described in a twelve year old boy who presented with ophthalmic complications. The literature is reviewed to emphasize the potential dangers of this condition.
Background
This study aimed to determine the impact of pulmonary complications on death after surgery both before and during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic.
Methods
This was a patient-level, comparative analysis of two, international prospective cohort studies: one before the pandemic (January–October 2019) and the second during the SARS-CoV-2 pandemic (local emergence of COVID-19 up to 19 April 2020). Both included patients undergoing elective resection of an intra-abdominal cancer with curative intent across five surgical oncology disciplines. Patient selection and rates of 30-day postoperative pulmonary complications were compared. The primary outcome was 30-day postoperative mortality. Mediation analysis using a natural-effects model was used to estimate the proportion of deaths during the pandemic attributable to SARS-CoV-2 infection.
Results
This study included 7402 patients from 50 countries; 3031 (40.9 per cent) underwent surgery before and 4371 (59.1 per cent) during the pandemic. Overall, 4.3 per cent (187 of 4371) developed postoperative SARS-CoV-2 in the pandemic cohort. The pulmonary complication rate was similar (7.1 per cent (216 of 3031) versus 6.3 per cent (274 of 4371); P = 0.158) but the mortality rate was significantly higher (0.7 per cent (20 of 3031) versus 2.0 per cent (87 of 4371); P < 0.001) among patients who had surgery during the pandemic. The adjusted odds of death were higher during than before the pandemic (odds ratio (OR) 2.72, 95 per cent c.i. 1.58 to 4.67; P < 0.001). In mediation analysis, 54.8 per cent of excess postoperative deaths during the pandemic were estimated to be attributable to SARS-CoV-2 (OR 1.73, 1.40 to 2.13; P < 0.001).
Conclusion
Although providers may have selected patients with a lower risk profile for surgery during the pandemic, this did not mitigate the likelihood of death through SARS-CoV-2 infection. Care providers must act urgently to protect surgical patients from SARS-CoV-2 infection.
We report a case in which a squamous cell carcinoma was found to have arisen from a delto-pectoral skin flap used in pharyngeal reconstruction. The flap had been forming a neo-pharynx for 24 years. No other signs of recurrent disease had developed in this period. This raises the possibility of tumour induction in heterotopic skin used for oropharyngeal reconstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
