Otolaryngology burden of disease and surgical case triage in resource-limited settings: An example from Cameroon.

OBJECTIVES: Otolaryngology services worldwide faced an unprecedented demand for case triage during the SARS-CoV-2 pandemic. We propose and apply a novel case-leveling schema in a resource-limited setting. Describing the surgical burden of otolaryngologic disease in this setting may critically inform resource planning to address global surgical disparities. METHODS: This is a retrospective study of otolaryngology cases performed over a 28-month period (1/2016-4/2018) at a hospital in rural Cameroon. Case details were collated and categorized as a surrogate measure of otolaryngologic disease in resource-limited settings. A case-levelling schema based on temporal urgency and anticipated impact on health was proposed and applied. RESULTS: 1277 cases took place during the study. The largest proportion of cases were head and neck (517, 40%), followed by pediatrics (316, 25%). A four-tiered leveling system was generated: level 1 cases were immediately life-saving; level 2 cases were expected to result in a significant return to functions of daily living, or would prevent future death from cancer; level 3 cases aimed to significantly improve quality of life; level 4 cases were purely elective. Upon application of the schema, most cases were deemed to be level 2 (661, 52%). CONCLUSION: We use our experience in a resource-limited setting to generate and apply a novel schema to be used for otolaryngology case triage in services facing unprecedented states of emergency such as the SARS-CoV-2 pandemic. This is the first study describing the surgical otolaryngologic disease burden in a resource-limited setting, data which may be used for future resource allocation. LEVEL OF EVIDENCE: 4.

Is AJCC/UICC Staging Still Appropriate for Head and Neck Cancers in Developing Countries?

By 2030, 70% of cancers will occur in developing countries. Head and neck cancers are primarily a developing world disease. While anatomical location and the extent of cancers are central to defining prognosis and staging, the American Joint Committee on Cancer (AJCC)/International Union Against Cancer (UICC) have incorporated nonanatomic factors that correlate with prognosis into staging (eg, p16 status of oropharyngeal cancers). However, 16 of 17 head and neck surgeons from 13 African countries cannot routinely test for p16 status and hence can no longer apply AJCC/UICC staging to oropharyngeal cancer. While the AJCC/UICC should continue to refine staging that best reflects treatment outcomes and prognosis by incorporating new nonanatomical factors, they should also retain and refine anatomically based staging to serve the needs of clinicians and their patients in resource-constrained settings. Not to do so would diminish their global relevance and in so doing also disadvantage most of the world's cancer patients.

Laparoscopy Using Room Air Insufflation in a Rural African Jungle Hospital: The Bongolo Hospital Experience, January 2006 to December 2013.

INTRODUCTION: Carbon dioxide is the standard insufflation gas for laparoscopy. However, in many areas of the world, bottled carbon dioxide is not available. Laparoscopy offers advantages over open surgery and has been practiced using filtered room air insufflation since 2006 at Bongolo Hospital in Gabon, Africa. OBJECTIVE: Our primary goal was to evaluate the safety of room air insufflation related to intraoperative and postoperative complications. Our secondary aim was to review the types of cases performed laparoscopically at our institution. METHODS: This retrospective review evaluates laparoscopic cases performed at Bongolo Hospital between January 2006 and December 2013. Demographic and perioperative information for patients undergoing laparoscopic procedures was collected. Insufflation was achieved using a standard, oil-free air compressor using filtered air and a standard insufflation regulator. RESULTS: A total of 368 laparoscopic procedures were identified within the time period. The majority of cases were gynecologic (43%). There was a 2% (8/368) complication rate with one perioperative death. The 2 complications related to insufflation were episodes of hypotension responsive to standard corrective measures. No intracorporeal combustion events were observed in any cases in which the use of diathermy and room air insufflation were combined. The other complications and the death were unrelated to the use of insufflation with air. CONCLUSION: Insufflation complications with room air occurred in our study. However, the complications related to insufflation with room air in our study were no different than those described in the literature using carbon dioxide. As room air is less costly than carbon dioxide and readily available, confirming the safety of room air insufflation in prospective studies is warranted. Room air appears to be safe for establishing and maintaining pneumoperitoneum, making laparoscopic surgery more accessible to patients in low-resource settings.
