Necrotizing Soft Tissue Infections of the Breast: A Potentially Lethal Surgical Emergency.

Necrotizing soft tissue infection (NSTI) of the breast is an extremely rare event in surgical practice. It is considered the most aggressive form of soft tissue infection and a true surgical emergency. It is also associated with a high risk of mortality if not diagnosed promptly. Few cases have been documented in the literature; the exact etiology and risk factors vary from those involving the limbs, trunk, and perineum. Early recognition, prompt surgical treatment, and broad-spectrum antibiotic therapy are crucial for reducing morbidity and mortality. These reports present cases of NSTIs in breasts with unique etiologies and challenges in their management.

Clinical yield of screening colonoscopies in Jamaica.

There is still no organised national screening programme for colorectal cancer in Jamaica. We sought to evaluate the detection of colorectal cancer precursor lesions in patients who underwent opportunistic screening over three years. Patients with colorectal polyps were selected for further study. In 431 procedures, there were 84 (19.5%) patients with colorectal polyps identified at screening colonoscopy, which gave a 19.5% sensitivity to identify patients with polyps at risk of developing colorectal cancer, 9.5% being <50 years of age. At the time of examination, 16.7% had already developed invasive adenocarcinoma. We conclude that it is time for policy makers to develop a national colorectal cancer screening programme to diagnose patients early and improve their therapeutic outcomes.

Congenital Dual Internal Hernias Causing Small Bowel Obstruction in a Man with no Prior Surgical History: A Report of a Very Rare Case.

BACKGROUND Internal hernias involve protrusion of the small bowel through a peritoneal or mesenteric space in the abdominal or pelvic cavity. Congenital internal small bowel hernias are rare and patients with them usually present with small bowel obstruction (SBO) at a young age, whereas in older patients, internal small bowel hernias usually are acquired secondary to previous surgery. The present report is of a rare case of SBO due to dual congenital internal small bowel hernias in a 51-year-old man with no history of abdominal surgery. CASE REPORT We report a case of dual congenital internal hernias of the small bowel in a patient who presented with symptoms and signs of SBO. He had no history of abdominal trauma, surgery, or comorbid conditions. His abdomen was mildly distended with minimal tenderness in the upper left quadrant but there was no guarding or rebound tenderness. Abdominal X-rays confirmed the SBO. A contrast-enhanced computed tomography scan of the patient's abdomen revealed SBO with transition at 2 points, suggestive of a closed-loop obstruction. However, the exact cause of the SBO was confirmed at laparotomy, which revealed dual internal hernias (intramesosigmoid and paraduodenal). The hernias were managed individually and the patient had a successful outcome after surgery. CONCLUSIONS Although the present report is of a rare presentation of internal small bowel hernia, the case underscores that patients with this condition may present with SBO. Successful surgical management requires knowledge of the intra-abdominal peritoneal spaces and management of the hernia sac.

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.

Epidemiology of neoplastic colorectal polyps in a Caribbean country.

Screening is practiced to identify and remove neoplastic colorectal polyps prior to their transformation into colorectal cancer (CRC). The aim of the present study was to document the epidemiology of neoplastic colorectal polyps in order to obtain important data that may then be used to guide screening protocols in Jamaica. For this purpose, an audit was performed to identify all consecutive patients who had neoplastic polyps detected at a screening colonoscopy at a facility in Jamaica from January 1, 2015 to December 30, 2018. The following data were collected: Patient demographics, polyp location, polyp synchronicity and histopathological information. The results revealed that a total of 480 colonoscopies were performed over the study period. With the exclusion of 2 patients with innumerable polyps as a part of polyposis syndrome, there were a total of 92 neoplastic polyps in 68 patients. Polyps were most commonly located in the right colon (55.6%), followed by the left colon (38%) and rectum (6.5%). Upon the histological evaluation, 63 polyps were found to be benign adenomas with mild to moderate dysplastic alterations, 15 were adenomas with severe dysplasia and/or carcinoma in situ and 14 had foci of invasive carcinomas. On the whole, the present study demonstrates that ~15% of the patients screened had neoplastic polyps that were recognized as precursor lesions for CRC. The majority of these were in the right colon. These results support the call for policy makers to institute national CRC screening programs, such as the National Comprehensive Cancer Network harmonized guidelines for the Caribbean.

Inferior Hepatic Fissures: Anatomic Variants in Trinidad and Tobago.

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.
