Medical Milestone in Diagnosis of Lung Ailments

It will now be much easier to diagnose lung diseases at Kenyatta National Hospital following the success of a ground-breaking procedure at the facility.A  team of medics at Kenya’s premier referral hospital employed the latest technology to obtain samples of tissue from the lungs of a 64-year-old patient, enabling them to make a swift and accurate diagnosis.

This marks the first time the process, widely known as Transbronchial Lung Cryobiopsy (TBLC), has been carried out in a public hospital in Kenya. A transbronchial cryobiopsy involves removing large pieces of tissue from the lung through bronchoscopy under general anaesthesia. Medics say this minimally invasive process is a safe and effective way of diagnosing potential problems within the organ.


Dr. Wanjiku Kagima, who heads the Medicine Department led the team of medics conducting
the procedure, explained that the intervention was prompted by a CT scan revealing a significant mass noted in the patient`s airways. Other medics involved in the procedure included Dr Joseph Mutie, a Cardiothoracic Surgeon,
Dr Peter Waweru, and Dr Naveed Merali, all guest Pulmonologists. The dedicated team also
included Nurses Joan Kagema, and John Ndung’u, as well as three anaesthetists Dr. Brenda Lasoi, Dr. Gathukia Kinyua and Dr. Hazo Oginga.


“TBLC is a minimally invasive technique allowing biopsy without major surgery. This innovative
technology holds significant promise for accurately diagnosing various conditions such as Interstitial Lung Diseases and Lung Cancer, while also aiding in the removal of foreign objects obstructing the airway,” she stated. A trans bronchial cryobiopsy procedure usually takes approximately one hour to conclude.
During the procedure, a doctor passes a flexible bronchoscope into the lungs to examine the airways. To locate the target, the cryoprobe via bronchoscopy, (technique used to look at your air passages with a small camera that is located at the end of a flexible tube), is advanced during cryobiopsy. After freezing the cryoprobe for 3 to 4 seconds, the flexible bronchoscope and cryoprobe are simultaneously pulled back, followed by immediate inflation of the endobronchial balloon for hemostasis (the mechanism that leads to cessation of bleeding from a blood vessel) Dr. Kagima further elaborated, “In the event hemostasis is not achieved, Argon Plasma Coagulation (APC) can be employed to achieve it, enabling effective debulking.” Debulking refers to the process where a specialist removes as much of a large mass as possible; to remove airway obstructions which enables a patient to breathe with ease.

This ground-breaking procedure promises reduced hospital stays and quicker recovery times compared to conventional thoracic surgery. This represents a novel approach to patient management. Kenyatta National Hospital Chief Executive Officer, Dr. Evanson Kamuri CBS, EBS, hailed the team for another interventional milestone. “This is an internal medicine and institutional landmark. We have attained yet another achievement in fulfilling our mandate as a top premier referral hospital,” he said. “I’d like to thank the team of doctors and those assisting them for a job well done. This confirms that we have the very best of medics and technology at KNH,” he concluded.
