Colorectal cancer in an Eastern Caribbean nation: are we missing an opportunity for secondary prevention?

Objective: To establish whether there was any difference in disease stage in patients with screening-detected colorectal cancer (CRC) in a Caribbean country. Methods: The mode of presentation (elective vs. emergent), method of diagnosis (screening vs. symptomatic), and disease stage were retrospectively compared in all consecutive patients who had resections for CRC over a five-year period. Early CRC was defined as disease that could be completely resected with no involvement of adjacent organs, lymph nodes, or distant sites. Locally advanced CRC was disease that involved contiguous organs without distant metastases that was still amenable to curative resection. Results: There were 97 patients at a mean age of 64.9 ± 12.2 years treated for CRC, and only 21 (21.6%) had their diagnoses made through screening. Significantly more screening-detected lesions were early-stage CRCs (21.7% vs. 9.3%; p < 0.001). At the time of diagnosis, patients who did not have screening-detected lesions had a greater proportion of locally advanced (42.3% vs. 0) and metastatic (26.8% vs. 0) CRC. Those who did not have screening-detected lesions had a greater incidence of emergency presentations at diagnosis (26.8% vs. 0). Conclusions: The incidence of screening-detected CRC in this Caribbean nation was low. Consequently, most patients presented with locally advanced or metastatic CRC, for which there is less opportunity to achieve a cure. Significantly more screening-detected lesions were early-stage CRCs. It is time for policymakers to develop a national CRC screening program.

Colorectal resections for malignancy: A pilot study comparing conventional vs freehand robot-assisted laparoscopic colectomy.

BACKGROUND: Laparoscopic colectomy is widely accepted as a safe operation for colorectal cancer, but we have experienced resistance to the introduction of the FreeHand® robotic camera holder to augment laparoscopic colorectal surgery. AIM: To compare the initial results between conventional and FreeHand® robot-assisted laparoscopic colectomy in Trinidad and Tobago. METHODS: This was a prospective study of outcomes from all laparoscopic colectomies performed for colorectal carcinoma from November 29, 2021 to May 30, 2022. The following data were recorded: Operating time, conversions, estimated blood loss, hospitalization, morbidity, surgical resection margins and number of nodes harvested. All data were entered into an excel database and the data were analyzed using SPSS ver 20.0. RESULTS: There were 23 patients undergoing colectomies for malignant disease: 8 (35%) FreeHand®-assisted and 15 (65%) conventional laparoscopic colectomies. There were no conversions. Operating time was significantly lower in patients undergoing robot-assisted laparoscopic colectomy (95.13 ± 9.22 vs 105.67 ± 11.48 min; P = 0.045). Otherwise, there was no difference in estimated blood loss, nodal harvest, hospitalization, morbidity or mortality. CONCLUSION: The FreeHand® robot for colectomies is safe, provides some advantages over conventional laparoscopy and does not compromise oncologic standards in the resource-poor Caribbean setting.

Multicenter Study of Laparoscopic Common Bile Duct Exploration for Choledocholithiasis in the English-Speaking Caribbean.

Background Common bile duct (CBD) exploration to address choledocholithiasis is not widely practiced in the English-speaking Caribbean. This study sought to determine the frequency of laparoscopic CBD explorations in the English-speaking Caribbean and to document the stone clearance rates and short-term outcomes of this procedure. Methods We accessed records for all practicing laparoscopic surgeons in the English-speaking Caribbean who performed laparoscopic CBD explorations over a 10-year period from January 1, 2013, to June 30, 2023. The following data were extracted retrospectively from patient records: demographic details, operating time, stone clearance rates, retained stone rates, conversions, and complications. All data were analyzed with SPSS version 20 (IBM Corp., Armonk, NY). Results Over the 10-year study period, 35 patients underwent laparoscopic cholecystectomy and synchronous CBD exploration in Barbados, Cayman Islands, Guyana, Grenada, St Lucia, and Trinidad & Tobago. The procedure was performed at low volumes of only 0.7 procedures per surgical team per annum. The conversion rate to open CBD exploration was 13% and when laparoscopic CBD exploration was completed, it resulted in 96.3% stone clearance, 3.7% retained stones, mean hospitalization of two days, 9.7% minor morbidity, and no mortality. Conclusion Laparoscopic CBD exploration is feasible in the resource-poor Caribbean setting, and it yields good results, with 96.3% stone clearance rates, 9.7% minor morbidity, and no mortality. These results are better than those reported in Caribbean literature for stone extraction with endoscopic retrograde cholangiopancreaticography (ERCP).

The utility of the Altemeier procedure in strangulated rectal procidentia secondary to rectal cancer. A case report.

INTRODUCTION AND IMPORTANCE: Altemeier rectosigmoidectomy has been cited in the literature as a suitable approach for incarcerated rectal prolapse when a large segment of bowel is involved. However, the literature is devoid of cases that employed the technique as an oncological procedure for rectal carcinoma. For this reason, this case report heralds a new perspective on an old technique. CASE PRESENTATION: We describe the case of a male in his 6th decade who presented with stage four rectal cancer. Computed tomography imaging showed a rectal mass at the rectosigmoid junction with pelvic lymphadenopathy and a solitary hepatic lesion in segment two of the liver. While admitted to the hospital a 16 cm segment of bowel containing the mass prolapsed and became incarcerated, eventually becoming necrotic. A modification of the Altemeier procedure was performed along with a diverting ileostomy and hepatic wedge resection of the solitary metastases. Histological assessment of the surgical specimens confirmed that adequate resection margins were obtained with one of twenty-one lymph nodes positive for malignancy. He is currently being followed up in the outpatient oncology clinic and has commenced adjuvant chemotherapy. CLINICAL DISCUSSION: Synchronous excision of rectal carcinoma with hepatic metastasectomy is a feasible surgery even in the emergency setting and can offer improved patient survival. CONCLUSION: The combination of both an abdominal and perineal approach was suitable for this patient given his improved quality of life and negative pathological margins.

Post-operative haemorrhage secondary to cinnamon use. A case report.

INTRODUCTION: Herbal medicine plays a significant role in modern medicine. The difficulty in integrating the two, lies in the unknown quantities of active ingredients in herbal remedies. This proved true in this clinical scenario. The quantity of coumarin, in the form of cinnamon ingested by this patient over ten months is unknown. The only quantifiable measure was the derangement in his extrinsic coagulation pathway. PRESENTATION OF CASE: A 49-year-old male with a history of celiac disease presented with haematochezia secondary to a malignant adenocarcinoma of the transverse colon. The patient underwent a laparoscopic subtotal colectomy and on the second post-operative day, he was noted to have peritonitis and a positive Fox sign. Diagnostic laparoscopy confirmed intraabdominal bleeding. Over the next four days, the patient's haemoglobin plummeted from 17.4 g/dL to 8.0 g/dL. Investigations revealed an INR of 1.59, which led to further questioning into dietary practices. The patient admitted he had been taking Ceylon cinnamon one tablespoon daily for ten months in the period leading up to surgery. DISCUSSION: Coumarin is a chemical compound readily available in food items such as cinnamon. Coumarin possesses the ability to inhibit vitamin K epoxide reductase complex 1 which is responsible for the recycling of vitamin K. This impedes the gamma-carboxylation of coagulation factors II, VII, IX, X. Vitamin K antagonism can manifest as a prolonged INR and normal activated partial thromboplastin time. CONCLUSION: Bleeding diathesis secondary to dietary coumarin is a rare but dangerous phenomenon that emphasizes the need for a thorough interrogation into a patient's dietary history.

Epidemiology of colorectal cancer in Barbados: A short report.

Barbados is a Caribbean island with a high incidence of colorectal cancer. This study collected epidemiologic data from Barbadian patients with colorectal cancer. There was an opportunity for targeted screening in patients actively enrolled in clinics for management of chronic diseases, accounting for 72% of cases. We also identified areas of high incidence where resources should be directed in a screening programme.

Time to abandon the old dictum of delayed laparoscopic cholecystectomy after acute cholecystitis has settled in Caribbean practice.

Although laparoscopic cholecystectomy is the gold standard treatment for acute cholecystitis, many Caribbean surgeons are reluctant to operate during the acute attack. We collected data for all consecutive patients who underwent laparoscopic cholecystectomy for acute cholecystitis from January 1 to 31 December 2018. Delayed cholecystectomy was done >6 weeks after acute cholecystitis settled. We compared data between early and delayed groups. Delayed laparoscopic cholecystectomy was performed in 54 patients, and 42 had early laparoscopic cholecystectomy. Delayed surgery resulted in significantly more complications requiring readmission (39% vs 0), longer operations (2.27 vs 0.94 h) and lengthier post-operative hospitalisation (1.84 vs 1.1 days). Caribbean hospitals should abandon the practice of delayed surgery after cholecystitis has settled. Early laparoscopic cholecystectomy would be financially advantageous for our institutions, and it would save patients recurrent attacks of gallstone disease.

Colorectal cancer demographics in Barbados.

Barbados is an island in the Eastern Caribbean that is reported to have the 8th highest incidence of colorectal cancer (CRC) worldwide. However, these figures are based only on estimates, and there is little available epidemiological data collected from Barbadians with CRC. The present study sought to collect epidemiologic data from patients in Barbados diagnosed with CRC. This information is considered important to shape national public health policies. For this purpose, hospital admission registers at all tertiary care facilities in Barbados were retrospectively audited over a four-year period from January 1, 2014 to December 31, 2018 to identify patients who underwent operative treatment for CRC. The following data were extracted: Age, sex, ethnicity, the location of the primary tumour and tumour stage. Descriptive statistical analyses were generated using SPSS version 21.0. The results revealed that there were 97 patients with CRC at a mean age of 64.9 years (SD ±12.2) and a male preponderance (1.3:1). The majority (93.8%) were from the African diaspora. Only 18.5% of diagnoses were made at (opportunistic) screening. Consequently, two thirds of the patients had advanced-stage disease at diagnosis. The disease staging of the patients was as follows: Stage 0 (1%), stage I (10.3%), stage II (23.7%), stage III (38.1%) and stage IV (26.8%). Right-sided primary tumours were most common (44.3%), followed by left-sided (41.2%) and rectal lesions (14.4%). Women were significantly more likely to have right-sided lesions (55 vs. 45%) and males were more likely to have rectal lesions (77 vs. 23%). On the whole, the present study highlights the need to implement a national screening programme in this high-risk population of African origin with a predominantly right-sided distribution of CRC primary tumours. This is reinforced by the fact that 10% of patients will be diagnosed before the age of 50 years with more aggressive disease.

Laparoscopic Liver Resection by Distance Mentoring - Trinidad to Barbados: A Report.

Laparoscopic liver resections require advanced laparoscopic skill sets. In the Caribbean, a unique situation exists where centers of excellence for liver resections exist, but surgeons who are trained in advanced laparoscopic surgery are not available throughout the region. Therefore, many patients who are candidates for liver resection in the Caribbean do not have the opportunity to receive laparoscopic operations.  We report a case of distance mentoring using readily available, inexpensive equipment to complete a laparoscopic liver resection, mentored by an expert hepatobiliary surgeon. It may be considered, in special cases, as a way to increase the availability of laparoscopic operations. We acknowledge that there are many limitations to the use of this technology and we discuss the pros and cons of distance mentoring for this purpose.

[RESUMEN]. Objetivo. Determinar las diferencias en el estadio de la enfermedad en pacientes con cáncer colorrectal diagnosticado mediante un programa de detección sistemática en un país del Caribe. Métodos. Se realizó una comparación en retrospectiva de la modalidad de presentación (programada o de urgencia), el método de diagnóstico (por detección sistemática o por síntomas) y el estadio de la enfermedad en todos los pacientes consecutivos con resecciones por cáncer colorrectal en un período de cinco años. Se definió el cáncer colorrectal en fase inicial o incipiente como una enfermedad que puede extirparse completamente sin la afectación de los órganos adyacentes, los ganglios linfáticos o focos distantes. Se consideró el cáncer colorrectal localmente avanzado como una enfermedad que afecta a los órganos contiguos sin metástasis a distancia y aún susceptible de resección curativa. Resultados. Hubo 97 pacientes de una media de edad de 64,9 ± 12,2 años en tratamiento por cáncer colorrectal y únicamente 21 (21,6%) habían recibido un diagnóstico mediante un programa de detección sistemática. Un número significativamente mayor de los diagnósticos dados por detección sistemática se trató de cáncer colorrectal de fase inicial (21,7 % frente a 9,3 %; p < 0,001). En el momento del diagnóstico, se registró una mayor proporción de cáncer colorrectal localmente avanzado (42,3 % frente a 0) y metastásico (26,8 % frente a 0) en los pacientes sin lesiones diagnosticadas en un programa de detección sistemática. Los pacientes cuyas lesiones no fueron diagnosticadas mediante la detección sistemática registraron una mayor incidencia de presentaciones de urgencia en el momento del diagnóstico (26,8 % frente a 0). Conclusiones. La incidencia de cáncer colorrectal diagnosticado mediante detección sistemática en este país del Caribe fue baja. En consecuencia, la mayoría de los pacientes presentó cáncer colorrectal localmente avanzado o metastásico, cuya oportunidad de cura es menor. Un número significativamente mayor de lesiones diagnosticadas mediante detección sistemática se trató de cáncer colorrectal de fase inicial. Ha llegado el momento de que las personas responsables de las políticas elaboren un programa nacional de detección sistemática de cáncer colorrectal.

[RESUMO]. Objetivo. Determinar se houve diferença no estágio da doença detectada no exame de prevenção de câncer colorretal em um país do Caribe. Métodos. Fatores como tipo de apresentação (eletiva vs. de emergência), método de diagnóstico (prevenção vs. detecção sintomática) e estágio da doença foram comparados retrospectivamente em todos os pacientes consecutivos submetidos a cirurgia de ressecção de câncer colorretal em um período de cinco anos. Definiu-se doença em estágio inicial como o tumor passível de ressecção total sem o envolvimento de órgãos adjacentes, gânglios linfáticos ou sítios a distância, e doença localmente avançada como o tumor envolvendo órgãos contíguos, sem metástase a distância, mas passível de resseção curativa. Resultados. Noventa e sete pacientes com média de idade de 64,9 ± 12,2 anos foram tratados devido ao câncer colorretal e apenas 21 (21,6%) tiveram a doença diagnosticada no exame de prevenção. Um percentual significativamente maior de lesões detectadas no exame de prevenção estava em estágio inicial (21,7% vs. 9,3%; p < 0.001). No momento do diagnóstico, os pacientes cujas lesões de câncer colorretal não foram detectadas com o exame de prevenção apresentaram um maior percentual de doença localmente avançada (42,3% vs. 0) ou metastática (26,8% vs. 0). Houve também, entre esses pacientes, uma maior incidência de apresentação em caráter de emergência (26,8% vs. 0). Conclusões. Observou-se uma baixa incidência de câncer colorretal na população deste país do Caribe. Porém, a maioria dos pacientes apresentou doença localmente avançada ou metastática no diagnóstico – uma situação associada a uma menor chance de cura. O percentual de lesões detectadas em estágio inicial com o exame de prevenção foi significativamente maior. As autoridades de saúde devem aproveitar a oportunidade e instituir um programa nacional de prevenção do câncer colorretal.
