A medical team on the road with a car, portable tools, and a clear goal has shown that advanced medical care can reach people who have been left behind for a long time. A study led by the Medical University of South Carolina (MUSC) Global Surgery Program and George Regional Hospital found that a mobile endoscopy service performed more than 500 diagnostic procedures in rural South Africa. These procedures found a lot of disease that wasn't being treated and cancers in their early, more treatable stages. 

The study, which came out in December 2025 in BMJ Open Gastroenterology, looked at procedures that happened between January and November 2024 in five district hospitals in the Western Cape of South Africa, where endoscopy is not usually offered. The results show both how common gastrointestinal illnesses are in rural areas and how it would work to bring professional care directly to patients. 

A healthcare gap that makes diagnosis take longer 

There aren't enough experts in South Africa—there are only 0.1 gastroenterologists for every 100,000 people. For people who live in rural areas, this means they have to wait up to nine weeks for a routine endoscopy and drive a long way to get care. At the same time, the country has one of the highest rates of Helicobacter pylori infections in the world. This strain is a common bacterium that can make the lining of the stomach swell and raise the risk of stomach cancer and ulcers. 

All of these things make it harder to get to the hospital and cause diseases to get worse and be diagnosed later. This is especially true in rural areas where the cost of travel and time away from work and family obligations can make it impossible to go. 

To fill this gap, doctors started a programme at George Regional Hospital called "endoscopy on wheels". A small group of people drove portable endoscopy equipment to each spot two to four times a month based on referrals. The MUSC Global Surgery Program helped with the project. Mike Mallah, M.D., and Hugo Stark, M.D., were in charge of it locally. 

What they found 

The marketing team did 515 procedures on 495 adults, most of whom were women and had an average age of 56. Upper endoscopies, in which a thin camera is put through the mouth to look at the food pipe and stomach, made up almost all of the operations. 

The data showed a widespread disease that can be treated. Gastritis, which means inflammation of the lining of the gut, was found in 76% of the patients. About 70% of them had a hiatal hernia, which is when part of the stomach pushes into the chest. Another 69% had oesophagitis, which is an inflammation of the food pipe. These health problems often lead to heartburn and pain that last for a long time. 

A lot of people had problems that were similar. Lead author Michael Deal, M.D., said that having gastritis, oesophagitis, and a hiatal hernia was common in people who had acid reflux for years without getting treatment. 

Most importantly, the tool found serious diseases early on. Twelve people were found to have oesophagus cancer, and five people were found to have stomach cancer. Seven of the patients were sent for more advanced care, such as surgery, which shows how important early identification is. 

Deal praised the people who worked hard on the scheme. "Dr Stark is a never-ending source of compassion. "That's what made him want to become a doctor, do surgery, and run this programme. It's what keeps him going on these long drives to care for his patients. 

Getting rid of travel and building trust 

Less travel was the most obvious effect right away. Patients had to drive about 63 miles to get to George Regional Hospital but just over eight miles to get to a mobile site. Each visit saved people in the most rural area an average of 137 miles. 

The change was huge for 18 patients from very rural areas. Together, they saved more than 1,800 miles of trip time. Deal said, "Not only did they possibly not have reliable transport, but they might also have jobs or family duties that making that trip would make impossible, even if it was just for half a day." 

The team built trust by going to the patients' neighbourhoods. Deal said, "They know that you have come to their community to give them the same level of care they would get at a major regional hospital." 

A model that applies around the world 

A study like this one found similar success in rural India. It shows that mobile, low-cost specialist services can help fill in the gaps in healthcare in low- and middle-income countries. The writers admitted that there were some problems, like the fact that topical throat anaesthetic was used and there were no long-term outcome data. However, they think that the study has a lot of room to grow. 

Deal said, "It would be amazing to take this kind of programme and make it bigger so that it includes more clinical support all over South Africa." "This is what we did for endoscopy." "Can we do this for surgery with minimal damage?" 

The show proves that distance doesn't have to stop people from getting timely care by bringing analysis to their door.
