RESUMEN

When the COVID-19 pandemic unfolded in March 2020, surgical care was impacted globally. The developing nations in the Caribbean were unprepared with fragile, resource poor healthcare systems. A series of rapid policy changes in response to the pandemic radically changed surgical care and prevented the usual oversight in the operating theatre. Attending surgeons responded utilising readily available technology for distance mentoring. Using this model, postgraduate surgical residents were able to complete 96% of trauma laparotomies safely without major complications.

RESUMEN

Intussusception in adults is rare. Even more unusual is jejunal intussusception secondary to a heterotopic pancreas. The presence of pancreatic tissue in an ectopic location and lacking contiguity with the main pancreatic gland is defined as pancreatic heterotopia. It is very rarely symptomatic and usually diagnosed incidentally during surgical intervention for other conditions. We report the case of a 78-year-old lady who presented with a history of constipation, abdominal pain, and vomiting. A CT scan revealed features of a proximal jejunojejunal intussusception secondary to a small soft tissue density lead point. After laparotomy and segmental jejunal resection, histopathology confirmed the diagnosis of ectopic pancreatic tissue as the lead point. Although uncommon, heterotopic pancreatic tissue should be included in the differential diagnosis for proximal small bowel intussusception.

RESUMEN

Classic descriptions of the visceral surface of the human liver only define three fissures: transverse, sagittal and umbilical fissures. Any additional fissures that are present on the visceral surface of the liver are considered variant inferior hepatic fissures (IHFs). This study was carried out to document the prevalence of IHFs in the Eastern Caribbean. Knowledge of these variants is important to clinicians who treat liver disorders in persons of the Caribbean diaspora. In this study, two independent researchers observed all consecutive autopsies performed at the facility over a period of 10 weeks. They examined the visceral surface of the unfixed liver in situ. Any specimen with variant IHFs was selected for detailed study. We documented the relation of the variant IHFs to nearby viscera and then explanted the livers using a standardized technique. The following details were recorded for each liver: number, location, depth, length, and width of IHFs. All measurements were checked independently by two researchers and the average measurement was used as the final dimension. Each liver was then sectioned in 1 cm sagittal slices to document the relationship of intraparenchymal structures. We observed 60 consecutive autopsies in unselected cadavers. Variant IHFs were present in 21 (35%) cadavers at a mean age of 68.25 years (range: 61 - 83; median 64.5; standard deviation (SD) ± 8.45). The variants included a deep fissure in the coronal plane between segments V and VI in 19 (31.7%) cadavers (related to the right branch of the portal vein in 63.2% of cases), a well-defined segment VI fissure running in a sagittal plane in four (6.7%) cadavers, a well-defined fissure incompletely separating the caudate process from the caudate lobe proper in five (8.3%) cadavers, a consistent fissure that arose from the left side of the transverse fissure and coursed between segments II and III in three (5%) cadavers, and a deep coronal fissure dividing the quadrate to form an accessory quadrate lobe in one (1.7%) cadaver. Almost one in three unselected persons in this population have anatomically variant fissures on the visceral surface of the liver. The variants include Rouvière's sulci (31.7%), caudate notches (8.3%), segment VI fissures (6.7%), left medial segment fissures (5%), and quadrate fissures (1.7%). The clinical relevance of these variants is discussed. Any clinician treating liver diseases in persons of Caribbean extract should be aware of their presence.

RESUMEN

The incidence of tongue carcinoma in Trinidad and Tobago and the greater West Indies is unknown; therefore, the present study examines the frequency of tongue carcinoma cases, drawing comparisons to worldwide and regional data. A retrospective analysis of all confirmed cases of tongue carcinoma was conducted using eight years of data from the pathology records at the Port of Spain General Hospital (Port of Spain, Trinidad and Tobago). A total of 26 cases were confirmed, of which 21 were male (81%) and five were female (19%). The age range was 29-86 years, with a mean age of 57 years, and the most common group affected was the 61-70 years age group. In addition, the number of newly diagnosed cases per year ranged between one and seven, with an average of 3.25 new cases per year and a peak incidence of seven new cases in the year of 2009. In the 19 cases where the degree of differentiation was recorded, histological analysis revealed the extent of differentiation as follows: Five cases (26%) were poorly-differentiated squamous cell carcinoma (SCC); eight cases (42%) were moderately-differentiated SCC; and six cases (32%) were well-differentiated SCC. In addition, one case of chronic inflammatory process and one case of mucoepidermoid adenocarcinoma of the tongue in a 57-year-old female were identified. Overall, the incidence of tongue carcinoma in Trinidad and Tobago appears to be low, estimated at 0.46/100,000 individuals/year. The male:female ratio is 4:1 and SCC is the dominant cancer type (96% of cases). The peak age of occurrence is at 61-70 years. These findings are in agreement with previously determined global data, however, additional research of the risk factors and outcomes of surgery as a treatment strategy for tongue carcinoma is required.

RESUMEN

BACKGROUND: An epidemiologic analysis of bone tumours in Trinidad & Tobago. METHODS: A retrospective analysis of primary and secondary bone tumours, site of origin and demographic data was conducted. RESULTS: 63 bone tumours were analysed and included 27 primary benign (43%), 12 primary malignant (19%), 19 metastatic (30%) and 5 by contiguous spread (8%). The most common malignant primary tumour was the osteosarcoma (n = 7), originating from the femur in mostly males in the 11-20 age group. There was 1 chondrosarcoma, 2 fibrosarcomas and 2 plasmacytomas. Benign tumours consisted of 8 osteochondromas, 2 osteomas, 3 giant cell tumours, 3 bone cysts and 11 cases of fibrous dysplasia. CONCLUSION: Bone tumours are rare with a low incidence of 1.125 per 100,000 population annually and malignant tumours being even rarer at an incidence of 0.18 per 100,000 population annually. There is need for better documentation and data registries in Trinidad and Tobago.

RESUMEN

BACKGROUND: We sought to determine the association between the presence of a fecalith and acute/nonperforated appendicitis, gangrenous/perforated appendicitis and the healthy appendix. METHODS: We retrospectively analyzed appendectomies performed between October 2003 and February 2012. We collected data on age, sex, appendix histology and the presence of a fecalith. RESULTS: During the study period, 1357 appendectomies were performed. Fecaliths were present in 186 patients (13.7%). There were 94 male (50.5%) and 92 female patients, and the mean age was 32 (range of 10-76) years. The fecalith rate was 13%- 16% and was nonexistant after age 80 years. The main groups with fecaliths were those with acute/nonperforated appendicitis (n = 121, 65.1%, p = 0.041) and those with a healthy appendix (n = 65, 34.9%, p = 0.003). The presence of fecaliths in the gangrenous/perforated appendicitis group was not significant (n = 19, 10.2%, p = 0.93). There were no fecaliths in patients with serositis, carcinoid or carcinoma. CONCLUSION: Our data confirm the theory of a statistical association between the presence of a fecalith and acute (nonperforated) appendicitis in adults. There was also a significant association between the healthy appendix and asymptomatic fecaliths. There was no correlation between a gangrenous/perforated appendix and the presence of a fecalith. The fecalith is an incidental finding and not always the primary cause of acute (nonperforated) appendictis or gangrenous (perforated) appendicitis. Further research on the topic is recommended.


CONTEXTE: Nous avons voulu examiner le lien entre la présence d'un fécalome et l'appendicite aiguë/non perforée, l'appendicite gangreneuse/perforée et un appendice sain. MÉTHODES: Nous avons analysé de manière rétrospective les appendicectomies effectuées entre octobre 2003 et février 2012. Nous avons recueilli des données sur l'âge, le sexe, l'histologie de l'appendice et la présence d'un fécalome. RÉSULTANTS: Durant la période de l'étude, 1357 appendicectomies ont été effectuées. Des fécalomes étaient présents chez 186 patients (13,7 %). L'étude regroupait 94 hommes (50,5 %) et 92 femmes; l'âge moyen était de 32 ans (entre 10 et 76 ans). Le taux de fécalome était de 13 % à 16 % et non existant après l'âge de 80 ans. Les principaux groupes porteurs de fécalomes étaient ceux qui présentaient une appendicite aiguë/non perforée (n = 121, 65,1 %, p = 0,041) et ceux dont l'appendice était sain (n = 65, 34,9 %, p = 0,003). La présence de fécalomes dans le groupe souffrant d'appendicite gangreneuse/perforée s'est révélée non significative (n = 19, 10,2 %, p = 0,93). Les patients qui souffraient de sérosite, de carcinoïde ou de carcinome ne présentaient pas de fécalomes. CONCLUSION: Nos données confirment la théorie d'un lien statistique entre la présence d'un fécalome et une appendicite aiguë (non perforée) chez l'adulte. On a également observé un lien significatif entre un appendice sain et des fécalomes asymptomatiques. On n'a observé aucune corrélation entre un appendice gangreneux/perforé et la présence de fécalomes. Le fécalome est une observation accessoire qui n'est pas toujours la principale cause de l'appendicite aiguë (non perforée) ou de l'appendicite gangreneuse (perforée). Une recherche plus approfondie à ce sujet est recommandée.

RESUMEN

The epidemiology of parotid gland tumours in Trinidad and Tobago and the wider Caribbean is currently unknown. Therefore, an analysis of the pathological records was conducted to determine the pattern of this disease in Trinidad and Tobago. A retrospective analysis was conducted on all parotid gland tumours and the demographic and histological data were analysed. Data from 60 cases were collected over a period of 8 years (October, 2003 to February, 2012), including 56 primary and 4 secondary tumours (1 basal cell carcinoma and 3 metastatic tumours). The patients included 31 men and 29 women, with a mean age of 48.7 years and an age range of 21-73 years (peak age, 51-60 years). The surgical interventions included 53 superficial parotidectomies, 6 radical parotidectomies and 1 biopsy. Of the 56 primary tumours, 41 were benign [34 pleomorphic adenomas and 7 Warthin's tumours (adenolymphomas)], accounting for 73.2% of the cases. The malignant lesions included 6 squamous cell carcinomas, 3 mucoepidermoid carcinomas, 2 acinic cell carcinomas, 2 adenoid cystic carcinomas, 1 anaplastic carcinoma and 1 papillary carcinoma, accounting for 26.8% of the total cases, without any age predominance. The pattern of disease distribution was similar to that indicated by worldwide data, with benign primary lesions accounting for ~80% of the cases (pleomorphic adenomas, 80% and Warthin's tumours, 20%). The most common carcinomas were mucoepidermoid and adenoid cystic types, as indicated by worldwide data; however, in our series, squamous cell carcinoma was the most common type, followed by mucoepidermoid, acinic cell and adenoid cystic carcinomas. The present study will hopefully provide useful information on parotid pathology in Trinidad and Tobago and encourage further research in this field.

RESUMEN

A case of massive upper gastrointestinal bleeding in a 37-year-old female is presented showing a submucosal mass in the gastric body. At laparotomy a pedunculated submucosal mass was found located on the posterior wall at the junction of the body and antrum of the stomach, 8 cm from the pylorus. Pathology confirmed that it was a 4 cm benign gastric lipoma with a bleeding central ulcer. Gastric lipomas are rare, benign, typically submucosal tumors occurring in the gastric antrum. They are usually asymptomatic but can become symptomatic depending on size, location, and if there is ulceration of the lesion. These lesions may be mistaken as malignant tumors or present with upper GI bleeding or intussusception. The diagnosis can be made using a combination of upper endoscopy, endoscopic ultrasound, CT, and MRI with surgical excision being the definitive treatment of choice. We hope that this case highlights the fact that these lesions can present with massive upper GI haemorrhage and should be included in the diagnosis when appropriate.

RESUMEN

This is the first report of dengue haemorrhagic fever and dengue shock syndrome in Trinidad. Dengue infection was confirmed serologically or by viral isolation in five patients, aged 15 to 33 years, who presented with fever, thrombocytopenia and haemoconcentration. Three patients developed dengue shock syndrome, which was fatal; although there was no haemorrhagic tendency among these patients, bleeding occurred shortly before death in one of them. Two patients who had dengue haemorrhagic fever survived. The co-circulation of dengue virus serotypes 1, 2 and 4 in the Caribbean facilitates the development of dengue shock syndrome (DSS) or dengue haemorrhagic fever (DHF). Clinicans should therefore be aware of their clinical features, laboratory diagnosis and clinical management. Appropriate public health interventions and improved surveillance should be implemented to reduce the risk of DHS/DSS associated mortality in Trinidad and Tobago.(AU)

RESUMEN

Dengue is endemic throughout most of the Caribbean, and increased activity has been noted within recent times. The co-circulation of dengue virus serotypes 1, 2 and 4 has been a cause of concern regarding the development of dengue shock syndrome/dengue haemorrhagic fever. The clinical presentation, investigate findings and confirmatory evidence for dengue infection in four patients are described. In all cases, there were fever, marked thrombocytopenia and haemoconcentration. The youngest patient was 15 years old and the oldest was 53 years. In two cases, there was no haemorrhagic tendency but profound shock ensued. Bleeding occurred preterminally in one of these. Both patients with dengue shock syndrome died but the two cases of dengue haemorrhagic fever survived. Dengue infection was confirmed serologically in three cases and by viral isolation in the other. This, to our knowledge, is the first report of dengue haemorrhagic fever/dengue shock syndrome in Trinidad, and clinicians should be aware of the clinical features and management. It is also crucial that public health measures be put in place to minimize dengue virus-associated mortality in Trinidad (AU)
