First steps of laparoscopic surgery in Lubumbashi: problems encountered and preliminary results

Current state of minimally invasive general surgical practice in Africa: A systematic review and meta-analysis of the laparoscopic procedures performed and outcomes

BACKGROUND

Minimally invasive surgery, including laparoscopy and robotics, has significantly improved general surgical (GS) practice globally. While robot-assisted GS practice is yet to be adopted in the majority of Africa, laparoscopy has been utilized to improve surgical outcomes. This study aims to review the laparoscopic GS procedures (LGSPs) performed and evaluate outcomes such as conversion to open surgery, morbidity, and mortality in Africa.

METHODS

Four databases (PubMed, Google Scholar, WoS, and AJOL) were searched, identifying 8022 publications. Following screening, 40 studies across Africa that reported LGSPs (n ≥ 2) performed and outcomes met the inclusion criteria. A meta-analysis conducted using R statistical software estimated the pooled prevalences with the 95% CI of conversion, morbidity, and mortality.

RESULTS

A total of 6381 procedures performed in 15 African countries were analyzed in this study. Majority, 72.89%, of the procedures were performed in Senegal, South Africa, and Nigeria. The major procedures performed were cholecystectomy (37.09%), appendicectomy (33.36%), and diagnostic laparoscopy (9.98%). The meta-analysis revealed a conversion rate of 5% [95% CI: 4, 7]. Adhesion (28.13%), hemorrhage (16.67%), technical difficultly (12.50%), and equipment failure (11.46%) were the predominant indications for conversion. Surgical site infection (42.75%) was the major cause of morbidity. The prevalences of morbidity and mortality were 7% [95% CI: 5, 10] and 0.12% [95% CI: 0, 0.29], respectively.

CONCLUSION

A wide range of basic and advanced LGSPs were performed. The outcomes obtained indicate successful implementation of the laparoscopic approach. Importantly, this study serves as a foundational work for further research on minimally invasive surgery in Africa.

First experience in laparoscopic surgery in low and middle income countries: A systematic review

BACKGROUND

Laparoscopic surgery has reduced morbidity and mortality rates, shorter postoperative recovery periods and lower complication rates than open surgery. It is routine practice in high-income countries and is becoming increasingly common in countries with limited resources. However, introducing laparoscopic surgery in low-and-middle-income countries (LMIC) can be expensive and requires resources, equipment, and trainers.

AIM

To report the challenges and benefits of introducing laparoscopic surgery in LMIC as well as to identify solutions to these challenges for countries with limited finances and resources.

METHODS

MEDLINE, EMBASE and Cochrane databases were searched for studies reporting first experience in laparoscopic surgery in LMIC. Included studies were published between 1996 and 2022 with full text available in English. Exclusion criteria were studies considering only open surgery, ear, nose, and throat, endoscopy, arthroscopy, hysteroscopy, cystoscopy, transplant, or bariatric surgery.

RESULTS

Ten studies out of 3409 screened papers, from eight LMIC were eligible for inclusion in the final analysis, totaling 2497 patients. Most reported challenges were related to costs of equipment and training programmes, equipment problems such as faulty equipment, and access to surgical kits. Training-related challenges were reliance on foreign trainers and lack of locally trained surgeons and theatre staff. The benefits of introducing laparoscopic surgery were economic and clinical, including a reduction in hospital stay, complications, and morbidity/mortality. The introduction of laparoscopic surgery also provided training opportunities for junior doctors.

CONCLUSION

Despite financial and technical challenges, many studies emphasise the overall benefit of introducing laparoscopic surgery in LMICs such as reduced hospital stay and the related lower cost for patients. While many of the clinical centres in LMICs have proposed practical solutions to the challenges reported, more support is critically required, in particular regarding training.

Serious fungal diseases in Democratic Republic of Congo - Incidence and prevalence estimates

A literature review was conducted to assess the burden of serious fungal infections in the Democratic Republic of the Congo (DRC) (population 95,326,000). English and French publications were listed and analysed using PubMed/Medline, Google Scholar and the African Journals database. Publication dates spanning 1943-2020 were included in the scope of the review. From the analysis of published articles, we estimate a total of about 5,177,000 people (5.4%) suffer from serious fungal infections in the DRC annually. The incidence of cryptococcal meningitis, Pneumocystis jirovecii pneumonia in adults and invasive aspergillosis in AIDS patients was estimated at 6168, 2800 and 380 cases per year. Oral and oesophageal candidiasis represent 50,470 and 28,800 HIV-infected patients respectively. Chronic pulmonary aspergillosis post-tuberculosis incidence and prevalence was estimated to be 54,700. Fungal asthma (allergic bronchopulmonary aspergillosis and severe asthma with fungal sensitization) probably has a prevalence of 88,800 and 117,200. The estimated prevalence of recurrent vulvovaginal candidiasis and tinea capitis is 1,202,640 and 3,551,900 respectively.Further work is required to provide additional studies on opportunistic infections for improving diagnosis and the implementation of a national surveillance programme of fungal disease in the DRC.

First steps of laparoscopic surgery in a sub-Saharan African setting: a nine-month review at the Douala Gynaeco-Obstetric and Pediatric Hospital (Cameroon)

OBJECTIVES

To describe the first laparoscopic surgeries in a tertiary hospital in Cameroon.

METHODS

We carried out a descriptive study at the Douala Gynaeco-Obstetric and Pediatric Hospital (DGOPH). We examined the files of the 45 patients who underwent laparoscopic surgery from November 1, 2015 to July 31, 2016. Descriptive statistics were computed for patients' characteristics and surgical parameters.

RESULTS

Mean (SD) age was 36.8(11.9) years. Women made up 86.7% of the sample. Twelve patients (26.7%) had a previous laparotomy. Cash deposit (86.7%) was the main mode of payment. Thirty-two (71.1%) laparoscopies were gynaeco-obstetrical (GO) and 13 (28.9%) were digestive. Main indications were infertility (59.4%) and chronic cholecystitis (30.8%) for GO and digestive laparoscopies respectively. Mean (SD) durations were 89.1(57.5) and 55.5(41.0) minutes for digestive and GO laparoscopies respectively. Mean (SD) costs were 1065.4 (406.1) and 934.2 (657.0) USD for digestive and GO laparoscopies respectively. Mean (SD) lengths of hospital stays were 5.5 (2.5) and 5.5 (2.5) days for digestive and GO laparoscopies respectively. Local staff carried out all GO laparoscopies while foreign (Belgian) experts did digestive cases. Only one (2.2%) complication (colic perforation) was registered.

CONCLUSION

The beginnings of laparoscopy at the DGOPH were successful thanks to strong local leadership and Belgian technical assistance.
