Microsurgery in low- and middle-income countries: Results of 20 years of experience in Cambodia

BACKGROUND

Microsurgical free tissue transfer is the gold standard for reconstructing major bone or soft tissue defects but requires complex training, and specific resources. Therefore, some authors have stated that microsurgery is impossible in low- and middle-income countries.

METHODS

Patients from Khmer underwent free flap surgery at the Children's Surgical Centre in Phnom Penh between 2004 and 2023. Two non-governmental organizations facilitated the program: Rose Charities Cambodia provided the facilities, patients and local staff, and Doctors of the World provided the surgeons, and anesthetists. At least one Khmer surgeon was trained during these operations. Digital data were collected retrospectively, and analyzed in June 2023.

RESULTS

Fifty-six free flaps in 54 patients have been performed since 2004. The most frequent sites requiring reconstruction were the head and neck (35.7%), lower limbs (30.4%), and upper limbs (21.4%). The most frequent free flaps were free fibula (44.6%), gracilis (19.6%), and anterolateral thigh (16.1%). Among the 56 flaps, 41 (= 73.2%) were viable long-term and 15 (26.7%) were microsurgical failures. Sixteen flaps underwent revision in the operating room. Twenty-three flap-related complications were reported in 21 patients with mostly vascular thrombosis (n = 12), hematoma (n = 3) and infections (3). However, 83.3% had improved or were cured of their initial pathology after final surgical management.

CONCLUSIONS

Free flaps performed in our series as part of international surgical collaborations in a low-income country are feasible, but we experienced higher failure rates, and later revisions compared to the results in high-income countries. We identified several solutions to improve the microsurgery outcomes in low-income settings.

International pediatric surgery partnerships in sub-Saharan Africa: a scoping literature review

Background

Sub-Saharan Africa (SSA) faces a critical shortage of pediatric surgical providers. International partnerships can play an important role in pediatric surgical capacity building but must be ethical and sustainable.

Objective

The purpose of this study is to perform a scoping literature review of international pediatric surgery partnerships in SSA from 2009 to 2019. We aim to categorize and critically assess past partnerships to aid in future capacity-building efforts.

Methods

We performed a scoping literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR) guidelines. We searched the PubMed and Embase databases for articles published from 2009 to 2019 using 24 keywords. Articles were selected according to inclusion criteria and assessed by two readers. Descriptive analyses of the data collected were conducted in Excel.

Results

A total of 2376 articles were identified. After duplicates were removed, 405 articles were screened. In total, 83 articles were assessed for eligibility, and 62 were included in the review. The most common partnership category was short-term surgical trip (28 articles, 45%). A total of 35 articles (56%) included education of host country providers as part of the partnership. Only 45% of partnerships included follow-up care, and 50% included postoperative outcomes when applicable.

Conclusions

To increase sustainability, more partnerships must include education of local health-care providers, and short-term surgical trips must be integrated into long-term partnerships. More partnerships need to report postoperative outcomes and ensure follow-up care. Educating peri-operative providers, training general surgeons in common pediatric procedures, and increasing telehealth use are other goals for future partnerships.
