Cecal volvulus in rural Kenya: delayed presentation contributes to high mortality.

BACKGROUND: Cecal volvulus, which is a torsion involving the cecum, terminal ileum, and ascending colon around its own mesentery, results in a closed-loop obstruction. It is a rare reported cause of adult intestinal obstruction. This study aimed to review the clinical presentation, management, and outcomes at a rural, resource-limited referral center. METHODS: We performed a retrospective review of all patients with a diagnosis of cecal volvulus between January 1st, 2009 and December 31st, 2019 at Tenwek Hospital in Bomet, Kenya. The outcome of survival was compared by the time to presentation. Mortality was also compared with prior reports of intestinal obstruction at our institution. RESULTS: Thirteen patients were identified with a mean age of 52 years and a mean symptom duration of 5 days. All patients presented with abdominal pain and distension. Seven patients (54%) presented with perforation, gangrene, or gross peritoneal contamination. Identified risk factors were Ladds bands with malrotation, adhesions, and a sigmoid tumor. Procedures included primary resection and anastomosis (7), damage control (3) with anastomosis on second-look in 2 of these, simple surgical detorsion (1), and surgical detorsion and cecopexy (2). There were four mortalities (31%), of which all had delayed presentation with perforation and fecal contamination. Delays to presentation were associated with mortality (p = 0.03). Cecal volvulus resulted in increased perioperative mortality compared to all intestinal obstructions presenting to the institution (p < 0.0001). CONCLUSIONS: Cecal volvulus carries a high risk of mortality. A high index of suspicion and early consideration in the differential diagnosis of intestinal obstruction should be considered to reduce the mortality associated with the delay in preoperative diagnosis.

Design of a Novel Online, Modular, Flipped-classroom Surgical Curriculum for East, Central, and Southern Africa.

Objective: We describe a structured approach to developing a standardized curriculum for surgical trainees in East, Central, and Southern Africa (ECSA). Summary Background Data: Surgical education is essential to closing the surgical access gap in ECSA. Given its importance for surgical education, the development of a standardized curriculum was deemed necessary. Methods: We utilized Kern's 6-step approach to curriculum development to design an online, modular, flipped-classroom surgical curriculum. Steps included global and targeted needs assessments, determination of goals and objectives, the establishment of educational strategies, implementation, and evaluation. Results: Global needs assessment identified the development of a standardized curriculum as an essential next step in the growth of surgical education programs in ECSA. Targeted needs assessment of stakeholders found medical knowledge challenges, regulatory requirements, language variance, content gaps, expense and availability of resources, faculty numbers, and content delivery method to be factors to inform curriculum design. Goals emerged to increase uniformity and consistency in training, create contextually relevant material, incorporate best educational practices, reduce faculty burden, and ease content delivery and updates. Educational strategies centered on developing an online, flipped-classroom, modular curriculum emphasizing textual simplicity, multimedia components, and incorporation of active learning strategies. The implementation process involved establishing thematic topics and subtopics, the content of which was authored by regional surgeon educators and edited by content experts. Evaluation was performed by recording participation, soliciting user feedback, and evaluating scores on a certification examination. Conclusions: We present the systematic design of a large-scale, context-relevant, data-driven surgical curriculum for the ECSA region.
