Incorporation of a Global Surgery Rotation into an Academic General Surgery Residency Program: Impact and Perceptions.

INTRODUCTION: Global surgery is increasingly recognized as a vital component of international public health. Access to basic surgical care is limited in much of the world, resulting in a global burden of treatable disease. To address the lack of surgical workforce in underserved environments and to foster ongoing interest in global health among US-trained surgeons, our institution established a residency rotation through partnership with an academic hospital in Kijabe, Kenya. This study evaluates the perceptions of residents involved in the rotation, as well as its impact on their future involvement in global health. MATERIALS AND METHODS: A retrospective review of admission applications from residents matriculating at our institution was conducted to determine stated interest in global surgery. These were compared to post-rotation evaluations and follow-up surveys to assess interest in global surgery and the effects of the rotation on the practices of the participants. RESULTS: A total of 78 residents matriculated from 2006 to 2016. Seventeen participated in the rotation with 76% of these reporting high satisfaction with the rotation. Sixty-five percent had no prior experience providing health care in an international setting. Post-rotation surveys revealed an increase in global surgery interest among participants. Long-term interest was demonstrated in 33% (n = 6) who reported ongoing activity in global health in their current practices. Participation in global rotations was also associated with increased interest in domestically underserved populations and affected economic and cost decisions within graduates' practices.

Global Surgery: The Challenges and Strategies to Win a War That Must Be Won.

Background: Modern science has conquered seas, land, and space. Although great strides have been made in technology and infectious diseases, global surgery, which was reborn in 2015, has not made much progress. The burden of surgical disease in low- and middle-income countries remains seemingly unconquerable, and its growth unstoppable. The myriad challenges in meeting the surgical needs of 5 billion people has intrigued the author. Methods: The author collected the views of plastic surgeons on sources and impediments to the scale-up of plastic surgery in low- and middle-income countries, as well as potential strategies for overcoming these obstacles. The author then performed a literature search reviewing the topics that arose from those discussions. The author proposes a strategy using plastic surgery as a model surgical discipline. Results: A root-cause analysis suggests that the Alma Ata Declaration, with its focus on primary healthcare, is the probable genesis of global surgery (GS) woes. The absence of a clear GS community leader and the fragmented nature of GS advocates who operate in multiple silos, without a clear unified goal, are the primary reasons GS advocates have achieved so little on the ground. Conclusions: Global surgery requires a business model to sustainably meet the surgical needs of the 5 billion people globally. The proposed and implemented strategies must meet rigorous criteria to ensure sustainability, as quick-fix solutions are counterproductive. The development of centers of excellence offers a viable solution to problems that must be addressed successfully.

Glomus Tumors: A Systematic Review of the Sub-Saharan Africa Experience.

Background: Glomus tumors are rare benign tumors that were first described in 1812 by Wood. They arise from normal glomus apparatus, usually located in the reticular dermis of the body. Although glomus tumors are universal in occurrence, the sub-Saharan Africa experience has not been well documented. Methods: The authors performed a systematic literature review of eligible studies between 1960 and August 2023, using the terms "glomus," "tumor," "glomangioma," "glomangiomyoma," and "Africa." We also performed a search of the AIC Kijabe Hospital pathology department database of about 140,000 records, covering 30 years, for the terms "glomus tumor," "glomangioma" and "glomangiomyoma." Results: The systematic literature search and institutional database search produced a total of 74 patients who had glomus tumors. These patients had a lag of between 3 months and 20 years from symptom development to definitive treatment. Conclusions: There are very few reports of glomus tumors from sub-Saharan Africa in the current literature: the authors' histopathology database of 140,000 specimens had 46 glomus tumors (0.03%), and only 28 additional patients were found in literature from sub-Saharan Africa. The low numbers of African patients may indicate racial differences in the occurrence of glomus tumors, although this may also be due to failure of clinicians to recognize glomus tumors. The prolonged lag period between symptom development and definitive treatment for glomus tumors indicates the need for diligence in the diagnosis and treatment of a simple problem that is otherwise the cause of incapacitating pain and misery.

The State of Surgical Research in Sub-Saharan Africa: An Urgent Call for Surgical Research Trainers.

Background: Surgery in low- and middle-income countries (LMICs) is poorly developed because of years of neglect. Sustained research on global surgery led to its recognition as an indivisible and indispensable part of primary healthcare in 2015. However, this has had little visible effect on surgical ecosystems within LMICs, especially in sub-Saharan Africa (SSA). SSA surgical research systems strengthening, which includes skills transfer, with local priority setting driving the research agenda, is needed to propel global surgery into the future. Methods: The authors performed a literature review of the state of surgical research within SSA and also report the initial efforts of two research training nonprofits to empower young African surgeons with research skills. Results: Surgical research in SSA is disadvantaged even before it is birthed, facing monumental challenges at every stage of development, from research agenda determination to funding, study execution, and publication. Compared with a global output of 17.49 publications per 100,000 population, SSA produces 0.9 (P < 0.0001). The Surgeons in Humanitarian Alliance for Reconstructive, Research, and Education and Enabling Africa Clinical Health Research programs are involved in the longitudinal research mentorship of surgical residents within SSA; the improved quality of research and successful publications by participants suggest nascent steps in growing young surgical scientists. Conclusions: In the absence of an existing surgical research infrastructure within LMICs, global surgery research trainers should link up and collaborate to help develop a surgical research community that will provide the local data required to help transform the SSA surgical ecosystem.

Use of the osteomuscular dorsal scapular flap in the reconstruction of mandibular defects.

The gold standard for mandibular defect reconstruction is the fibular free flap. Nevertheless, the pedicled osteomuscular dorsal scapular flap as a reconstructive tool offers promise for mandibular defect reconstruction and could be the first choice in certain circumstances. Its use in resource-limited settings offers an excellent solution to otherwise difficult reconstructive problems of the mandible. In 8 patients, mandibular defects resulting from the excision of benign tumors (6), trauma (1), and chronic osteomyelitis (1) were reconstructed using the pedicled osteomuscular dorsal scapular flap; these defects included the central segment of the mandible. The pedicled osteomuscular dorsal scapular flap is an excellent choice for mandibular reconstruction; it may serve as the primary choice in patients with vascular pathology that precludes free tissue transfer, as well as in resource-limited environments, as a secondary choice after a failed free flap reconstruction.

Successful Shoulder Disarticulation under Local Anesthesia in the COVID-19 Era.

The use of the wide-awake local anesthesia no tourniquet, a tumescent local anesthetic technique in recent years, emerged as a powerful tool primarily in hand surgery. It has been adopted in many low- and middle-income countries where it was applied to an increasingly broad group of procedures. We report the case of an older patient with an arm liposarcoma for which surgery under general or regional anesthesia was deemed unsafe, but was successfully managed with a curative right shoulder disarticulation using tumescent local anesthesia.

Safety and Sustainability: Optimizing Outcomes and Changing Paradigms in Global Health Endeavors.

Background: The need to address inequities in global surgical care has garnered increased attention since 2015, after the Lancet Commission on Global Surgery underscored the importance of ensuring safe, accessible, affordable, and timely surgical and anesthetic care. The vast unmet global plastic surgery needs make plastic surgery care essential in reducing the global burden of disease. In the past, many nonprofit organizations undertook humanitarian activities within low- and middle-income countries that were primarily service-provision oriented. The Lancet Commission on Global Surgery report prompted a shift in focus from direct patient care models to sustainable global surgical models. The realization that 33% of deaths worldwide were due to unmet surgical needs led to a global shift of strategy toward the development of local systems, surgical capacity, and a focus on patient safety and quality of care within international global surgery partnerships. Methods: In this report, the authors explore some of the primary components of sustainable international global surgical partnerships discussed in a recent panel at the American Society of Plastic Surgeons Plastic Surgery The Meeting 2022, titled "Safety and Sustainability Overseas: Optimizing Outcomes and Changing Paradigms in Global Health Endeavors." A literature review elaborating the topics discussed was performed. Results: This report focuses on cultural competence and humility, international collaboration, and the use of technology and innovation, all of which are needed to promote sustainability and patient safety, within global surgery efforts. Conclusions: The adoption of these components into international surgical collaborations will lead to greatly enhancing the development and sustainability of mutually beneficial relationships.

Academic global surgical competencies: A modified Delphi consensus study.

Academic global surgery is a rapidly growing field that aims to improve access to safe surgical care worldwide. However, no universally accepted competencies exist to inform this developing field. A consensus-based approach, with input from a diverse group of experts, is needed to identify essential competencies that will lead to standardization in this field. A task force was set up using snowball sampling to recruit a broad group of content and context experts in global surgical and perioperative care. A draft set of competencies was revised through the modified Delphi process with two rounds of anonymous input. A threshold of 80% consensus was used to determine whether a competency or sub-competency learning objective was relevant to the skillset needed within academic global surgery and perioperative care. A diverse task force recruited experts from 22 countries to participate in both rounds of the Delphi process. Of the n = 59 respondents completing both rounds of iterative polling, 63% were from low- or middle-income countries. After two rounds of anonymous feedback, participants reached consensus on nine core competencies and 31 sub-competency objectives. The greatest consensus pertained to competency in ethics and professionalism in global surgery (100%) with emphasis on justice, equity, and decolonization across multiple competencies. This Delphi process, with input from experts worldwide, identified nine competencies which can be used to develop standardized academic global surgery and perioperative care curricula worldwide. Further work needs to be done to validate these competencies and establish assessments to ensure that they are taught effectively.

The supraclavicular artery flap: a versatile flap for neck and orofacial reconstruction.

PURPOSE: The supraclavicular skin is thin and pliable; it closely resembles that of the neck and facial skin, making it the perfect source of tissue for neck and orofacial reconstructions. The author sought to provide a concise compilation of the use of the supraclavicular artery flap, including surgical landmarks, modifications, uses, common complications, and anomalies, and experience with the use of the flap in a sub-Saharan African country. MATERIALS AND METHODS: A literature search was performed on the Internet and PubMed for anatomic and clinical studies/reports in the English language on the supraclavicular artery flap with a minimum of 10 subjects and sufficient data on postoperative complications. RESULTS: Five anatomic studies (2 of which included clinical cases) and 12 clinical series qualified for inclusion. These articles included 146 flaps from 73 cadaveric studies and 376 supraclavicular flaps in patients (including a series of 22 flaps by the present author). The supraclavicular artery was present in 99% of anatomic dissections and was a branch of the transverse cervical artery in 91% of anatomic dissections. Safe margins for elevation of the supraclavicular artery flap were delimited anteriorly by the clavicle, posteriorly by the superior border of the trapezius, and distally by the insertion of the deltoid muscle. Common flap complications included tip and partial flap necroses. The flap was used successfully in nononcologic and oncologic reconstructions, even with concurrent neck dissection. CONCLUSIONS: The pedicled supraclavicular fasciocutaneous flap is emerging as a versatile reconstructive tool for the neck and orofacial regions. It is an excellent option, especially in resource-poor environments and in patients in whom free flaps may be technically difficult. Anatomic and clinical studies have shown it to be consistently reliable, with excellent color matching for the face and neck regions, and have established reliable surgical landmarks, modifications, uses, common complications, and anomalies.

Osteosarcoma of the jaws: a review of literature and a case report on synchronous multicentric osteosarcomas.

BACKGROUND: In the head and neck region, osteosarcoma is the most common primary malignant bone tumor, representing 23% of total head and neck malignancies. Osteosarcomas of the jaws are nevertheless rare lesions, representing only 2 to 10% of all osteosarcomas. This report reviews a single-center histopathology experience with craniofacial osteosarcomas, and reports the management of unusually large synchronous mandibular and maxillary osteosarcomas in a patient. PATIENTS AND METHODS: A search of the hospital pathology database for specimens with a histological diagnosis of osteosarcomas submitted between July 1992 and May 2011 was made. A chart review of a patient with large synchronous maxillary and mandibular osteosarcomas was performed, and is reported. CASE PRESENTATION: A 21-year-old African man with large maxillary and mandibular tumors under palliative care presented with increasing difficulties with eating, speech, and breathing. Surgical debulking was performed, with histology confirming synchronous osteosarcomas of the mandible and maxilla. The patient is well after one year, with no evidence of recurrence, having undergone no further treatment. CONCLUSION: Osteosarcomas of the jaw remain enigmatic, and a number of difficulties related to their diagnosis and treatment are yet to be resolved. True synchronous multicentric osteosarcomas of the jaws are extremely rare but, like other osteosarcomas of the jaws, have a favorable outcome, and palliative resection of such lesions, though challenging, can therefore lead to an enormously improved quality of life and self-image, and may even offer the opportunity for cure.

Pediatric surgical site infection in the developing world: a Kenyan experience.

BACKGROUND: The purpose of the current study was to determine the incidence of pediatric surgical site infections(SSIs) at an academic children's hospital in rural sub-Saharan Africa and to identify potentially modifiable risk factors. METHODS: Prospectively collected data from 1,008 surgical admissions to Bethany Kids Kijabe Hospital (Kijabe, Kenya) were analyzed retrospectively. Follow-up data were available in 940 subjects. RESULTS: SSIs occurred in 6.8% of included subjects(N = 64). Superficial (69%) and deep (29%) infections of the back (38%) and head (25%) were most common. When comparing children who developed SSI to those who did not, we found that wound contamination classification and duration of operation were the only variables with significant differences between groups. CONCLUSIONS: Our rate of SSI among pediatric patients insub-Saharan Africa is the lowest reported in the literature to date. More work is needed to identify modifiable risk factors for pediatric SSI in low- and middle-income countries.

Surgical Antibiotic Prophylaxis in Children Undergoing Surgery: A Systematic Review and Meta-Analysis.

Background: To establish the role of surgical antibiotic prophylaxis (SAP) in the prevention of surgical site infection (SSI) in children undergoing surgery. Design: A systematic review and meta-analysis of six databases: MEDLINE (PubMed), EMBASE, CINAHL Plus, Cochrane Library, Web of Science, and Scopus. Study Selection: Included studies (irrespective of design) compared outcomes in children undergoing surgery, aged 0 to 21 years who received SAP with those who did not, with SSI as an outcome, using the U.S. Centers for Disease Control and Prevention (CDC) definitions for SSI. Data Extraction: Two independent reviewers applied eligibility criteria, assessed the risk of bias, and extracted data. Results: A total of six randomized control trials and 26 observational studies including 202,593 surgical procedures among 202,405 participants were included in the review. The pooled odds ratio of SSI was 1.20; (95% confidence interval [CI], 0.91-1.58) comparing those receiving SAP with those not receiving SAP, with moderate heterogeneity in effect size between studies (τ2 = 0.246; χ2 = 69.75; p < 0.001; I2 = 57.0%). There was insufficient data on many factors known to be associated with SSI, such as cost, length of stay, re-admission, and re-operation; it was therefore not possible to perform subanalyses on these. Conclusions: This review and metanalysis did not find a preventive action of SAP against SSI, and our results suggest that SAP should not be used in surgical wound class (SWC) I procedures in children. However, considering the poor quality of included studies, the principal message of this study is in highlighting the absence of quality data to drive evidence-based decision-making in SSI prevention in children, and in advocating for more research in this field.

Primary cutaneous malignancies in sub-Saharan Africa.

Cutaneous malignancies are the most common malignancies in Whites; traditionally considered rare among Blacks, their occurrence in sub-Saharan Africa is yet to be fully characterized.Data on specimens submitted between 1992 and April 2008 on all histologically proven primary cutaneous malignancies were collected from the Pathology Department, including patient age, sex, anatomic site of malignancy, and histologic diagnosis. There were 1900 patients with primary cutaneous malignancies, aged between 8 months and 110 years, with a mean age of 49 years. There were 14 different types of malignancies found, with squamous cell carcinoma representing 45% of the total. A number of the rarer types have not been reported previously, from this region.Cutaneous malignancies in Africa present a number of management challenges including the following: difficulties in early diagnosis in the dark skin, late presentation, access to treatment, and the ability to pay for the appropriate treatment. The current human immunodeficiency virus/acquired immune deficiency syndrome scourge on the continent may lead a significant increase in cutaneous malignancies, posing even bigger challenges.

Marjolin's ulcers in sub-Saharan Africa.

BACKGROUND: Cutaneous malignancies are considered rare among Africans. Trauma, its sequelae, and other chronic non-healing wounds are known to predispose to malignant degeneration. Not much is known of the demographics of Marjolin's ulcers in sub-Saharan Africa. METHODS: Pathology records on patients suspected to have Marjolin's ulcers submitted to the Pathology Department were extracted from a database of 75,124 specimens. A review of the English literature on Marjolin's ulcers from Nigeria, a sub-Saharan country, was also performed. RESULTS: Of 210 specimens from suspected Marjolin's ulcers, 167 records had a histological diagnosis of malignancy, with a male to female ratio of 1:1.4, and a mean age of 48 years (range: 4-97 years). There were 163 (97.6%) squamous cell carcinomas, 3 (1.8%) sarcomas, and 1 (0.6%) malignant melanoma. Burn scars, chronic ulcers, osteomyelitis, and "other" ulcers constituted 82 (49%), 70 (42%), 9 (5.4%), and 6 (3.6%), respectively. Subjects in six sub-Saharan Marjolin's ulcer studies had a mean age between 36 and 42 years, with a mean latent period 16 years. CONCLUSIONS: Marjolin's ulcers in sub-Saharan African have a shorter latent period, and they occur in younger patients. Provision of early stable wound cover is essential for prevention of malignant degeneration of scars, while early appropriate intervention is crucial in the treatment of chronic ulcers.

"Blitz surgery": redefining surgical needs, training, and practice in sub-Saharan Africa.

BACKGROUND: Most reconstructive surgery in Sub-Saharan Africa is provided by numerous noncoordinated individuals and organizations, in multiple short trips, or "surgical blitzes." Because many such groups do not train local surgeons, these communities have become dependent on unsustainable systems. By providing much-needed care to otherwise neglected areas, the blitzes offer an easy solution to what would otherwise be the source of a significant headache to local governments. METHODS: The collection of data and other material in this highly ambiguous and fluid field is nearly impossible, as scientific papers on the results of poor surgical treatment, especially in the realm of humanitarian medicine, do not exist: The author has had to rely on personal experience and community interaction to reach the views and conclusions articulated in this article. RESULTS: Although not the rule, blitz surgeries have poorer outcomes than in-hospital procedures, primarily because of inadequate preoperative and postoperative care. CONCLUSIONS: Although the value of blitz surgery in meeting some of the surgical needs of otherwise neglected communities is undeniable, the author seeks to provoke a sober reexamination of these efforts vis-à-vis the long-term sustainability of such programs, with the objective of harnessing strengths that would see the evolution of a new reconstructive surgical service tailor-made for Africa--affordable and sustainable yet able to deliver quality surgical care to the remotest villages. Otherwise, these humanitarian efforts' will continue to be 'drops in the ocean, meeting the needs of a few in the community but resulting in no long-term gains.

Marjolin's ulcers: theories, prognostic factors and their peculiarities in spina bifida patients.

BACKGROUND: Due to improved care, more and more children born with spina bifida in rural Kenya are surviving into adulthood. This improved survival has led to significant challenges in their lifestyles, especially the need to ensure pressure ulcer prevention and treatment. Malignant degeneration of pressure ulcers in spina bifida patients is very rare. The author describes the clinical presentation of two pressure ulcer carcinomas that are at variance from classical descriptions. MATERIALS AND METHODS: An internet/Medline/PubMed search of English literature for theories on Marjolin's ulcer evolution and prognostic features of Marjolin's ulcers was performed.A chart review of two young adults with spina bifida who had presented to the author's hospital between 2004 and August 2010 with chronic pressure ulcers found to be Marjolin's ulcers on histo-pathological examination was performed, and the clinical features are reported. RESULTS: The two ulcers appeared clinically benign: one was a deep ulcer, while the other was shallow; both had normal, benign-appearing edges, and a foul smelling discharge. The two ulcers were surrounded by induration and multiple communicating sinuses, with no evidence of chronic osteomyelitis. The internet search revealed a total of nine theories on Marjolin's ulcer development, as well as seven clinical and four histological prognostic features. DISCUSSION: The multifactorial theory, a coalescence of a number of proposed theories, best explains the evolution of Marjolin's ulcers. Poor prognostic features include pressure ulcer carcinomas, lesions and location in the lower limbs/trunks, all present in the two patients making their prognosis dim: this is despite the surgical margins being clear of tumor. Benign appearance, induration and presence of multiple communicating sinuses are features that have not been previously described as presenting features of pressure ulcers carcinomas. CONCLUSION: There is need for spina bifida patients and their guardians/caretakers to receive a close follow-up throughout life; health education focused on pressure ulcer prevention as well as early treatment of pressure ulcers when they occur, will avert the development of Marjolin's ulcers, and save lives.

Engineering an adhesive based on photosensitive polymer hydrogels and silver nanoparticles for wound healing.

Hemostasis, wound closure and prevention of infection are critical to wound healing after an injury. Skin adhesives have been used to seal incisions, thus aiding primary wound healing, as well as creating a barrier to microbes. We constructed a skin adhesive with antibacterial and hemostatic activities (AHAs) for wound management. The adhesive was made by using methacrylated hyaluronan-polyacrylamide (MHA-PAAm) hydrogels, integrated with silver nanoparticles (AgNPs) and bonded to gelatin. Because of the three-dimensional network structure of the hydrogels, nanoscale particles can be encapsulated into their voids; the AgNPs, through sustained delivery of silver ions, endow the adhesives with sustained broad-spectrum antibacterial activity. Furthermore, due to the introduction of MHA which can be crosslinked by visible light, the polyacrylamide hydrogel matrix can be formed through photo crosslinking. In addition, gelatin can be bonded to both the hydrogel matrix and host tissues because of the interaction between carboxyl and amino-moieties. Our animal studies demonstrated that the AHAs which possess tissue adhesive and antibacterial properties were easy to stretch, and were able to stop bleeding in rat tail amputation and liver injury models. AHAs enhance wound granulation tissue formation, vascular tissue formation, and collagen formation, as well as alleviate inflammation. These properties promoted wound closure in rat wound infection models, promising great potential for applying AHAs in clinical uses.
