Over 9000 surgical procedures are performed each year in the Department of Surgery. The core group of 9 surgeons includes 3 general surgeons, 2 orthopedic surgeons, 1 obstetrician-gynaecologist, 2 paediatric surgeons and 1 paediatric rehabilitation surgeon. This group is supported by a number of visiting surgeons representing neurosurgery, ENT, plastics, urology and orthopaedics. Kijabe Hospital is very grateful to these visitors who help in the management of complex surgical cases, teach our trainees, and allow our permanent staff to further their continuing medical education.

General surgery continues to be the mainstay of the department, with the majority of procedures done by general surgeons. Many of these cases would be done by other surgical specialists - such as neurosurgeons and urologists - in the major urban centres of Kenya or in developed countries. The expertise and training that visiting surgical staff provide is greatly appreciated.

Obstetrics/Gynaecology is comprised of a maternity ward, neonatal nursery, maternal child health clinic, satellite AIC peripheral 'mobile' health clinics and weekly gynaecology clinics. This department serves as a referral centre for high-risk obstetric and complicated gynaecologic cases.

BethanyKids at Kijabe Hospital (BKKH) is a paediatric surgical centre which was opened in November 2004. This highly specialized program was developed for the treatment of children with neurosurgical conditions (such as spina bifida and hydrocephalus) as well as a broad spectrum of otehr paediatric surgical conditions (such as intestinal problems, urologic conditions, burn contractures, cleft lip and palate, and others). BKKH provides valuable specialized training in paediatric surgery and neurosurgery for registrars through the Pan-African Academy of Christian Surgeons (PAACS) and the College of Surgeons of East, Central, and Southern Africa (COSECSA). 

The anaesthesia department provides general and regional anaesthesia (including over 1,500 spinal anaesthetics) for neonatal, paediatric and adult patients. The Nursing Council of Kenya has approved the Nurse Anaesthesia Training Program that was developed at KH. This program is the first of its kind in East Africa. Members of the department are also involved in the training of physicians at the University of Nairobi.
