Purpose: Bochdalek hernia is a congenital diaphragmatic hernia. The incidence in adults is estimated around 0.17%. Right-sided hernias are much more seldom than left-sided ones because of faster closure of the right pleuroperitoneal canal and the protective effect of the liver. Due to its rarity, there have been no large prospective or retrospective studies following great need for evidence-based diagnostics and treatment strategies. In this systematic review, we evaluated the current evidence of diagnostics, treatment, and follow-up of adult right-sided Bochdalek hernias. Methods: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines a systematic literature review was conducted in PubMed and Cochrane library from 2004 to January 2021. The literature search included all studies with non-traumatic right-sided Bochdalek hernias. Literature on left- or both-sided, pregnancy-associated, pediatric, and other types of hernias were explicitly excluded. Quality assessment of the included studies was performed. Results: Database search identified 401 records. After eligibility screening 41 studies describing 44 cases of right-sided non-traumatic Bochdalek hernias in adulthood were included for final analysis. Based upon the systematic literature review, the current diagnostic, therapeutic, and follow-up management pathway for this rare surgical emergency is presented. Conclusion: This systematic review underlined that most studies investigating management of adult non-traumatic right-sided Bochdalek hernias are of moderate to low methodological quality. Hernias tend to occur more frequently in middle-aged and older women presenting with abdominal pain and dyspnea. A rapid and accurate diagnosis following surgical repair and regular follow-up is mandatory. High-quality studies focusing on the management of this rare entity are urgently needed.

Introduction: Inguinal hernias are among the most common surgical diseases in Africa. The current International HerniaSurge Guidelines recommend mesh-based surgical techniques in Low Resource Settings (LRS). This recommendation is currently unachievable in large parts of Africa due to the unaffordability of mesh and lack of appropriate training of the few available surgeons. There is, therefore, a need for formal training in mesh surgery. There is an experience in Hernia Repair for the Underserved in Central and South America, however, inadequate evidence of structured training in Africa. Material and methods: Since 2016, the aid Organizations, Surgeons for Africa and Operation Hernia have developed and employed a structured hernia surgical training program for postgraduate surgical trainees and medical doctors in Rwanda. This course consists of lectures on relevant aspects of hernia surgery and hands-on training in operating theatres. The lectures emphasize anatomy and surgical technique. All parts of the training were evaluated. Formal pre-course evaluation was conducted to assess the personal surgical experience of the trainees. Results: Over a 3-year period, a structured hernia training programme was employed to train a total of 36 surgical trainees in both mesh and also non mesh hernia surgery. The key principle in this course is the continuous competence assessment and feedback. Evidence is provided to demonstrate improvement in surgical skills as well as knowledge of surgical anatomy which is essential to acquiring surgical competency. With self-assessment, expressed on a Likert scale, the participants could improve the theoretical knowledge about hernias from median 4.4 (on a scale of 1–10) before training to 8.4 after the training. The specific knowledge about anatomy could be improved in the same assessment from 4.8 before training to 8.1. after the training. After training course 12 of the 36 participants (33.33%) were able to carry out both suture- and mesh-based operations of simple inguinal hernias completely and independently. 20 of the 36 participants (55.55%) required only minimal supervision and only four participants (11.11%) required surgical supervision even after the completion of the course. Conclusion: We have demonstrated that, medical personnel in Africa can be trained in mesh and non-mesh hernia surgery using a structured training programme. [ABSTRACT FROM AUTHOR]
