Doctor's Profile

Dr. John Poole is in charge of the colorectal surgery unit of the largest public hospital in the country, San Juan de Dios, Guatemala and has been Surgical Chief and Faculty there since 1995. Since his own student residency in the early 1980’s, Dr. Poole has been a guiding force at San Juan de Dios teaching the latest medical advances to  medical students and surgical residents alike,  as well as diagnosing and treating his own patients with the precision and compassion that comes from over thirty years of clinical experience.

Dr. Poole likes to take a holistic approach to treating new patients, so he takes plenty of time with them to learn all aspects of their health and lifestyle. This holistic approach allows him to examine all potential contributing factors that affect total wellbeing and consider these factors in assessing overall health. He strives to assess patients carefully and methodically, to avoid any misunderstandings or unnecessary office visits.

“Many proctology problems like irritable bowel and constipation are the result of not eating properly, so I take extra time for nutritional consulting, to promote proper dietary habits.” says Dr. Poole. Research suggests that up to 35 percent of cancers are related to poor diet. By modifying what you eat and being active, you can reduce your risk of cancer and other health problems. Dr. Poole recommends to eat a diet with more fruits and vegetables and less red meat. Drink plenty of water and get exercise to promote overall good health.

With cancer being a leading cause of death world-wide, we take colonoscopies very seriously and work in collaboration with multi-disciplinary oncologists (cancer doctors) to evaluate, confer and ultimately determine the plan of treatment that will yield the best chance of successful outcome for our patients. Some people may require a polypectomy, which will remove intestinal growths that could become cancerous, or a local excision to remove a suspicious tumor. If colorectal cancer does occur, early detection and treatment dramatically increase chances of survival.  The relative 5-year survival rate for colorectal cancer, when diagnosed at an early stage before it has spread, is about 90%.

In addition to performing various general internal surgery procedures, Dr. Poole is especially well-versed in thyroid and endocrine problems. He has either lead or assisted in the majority of thyroid operations performed in Guatemala.

Dr Poole has treated thousands of patients from all over the world, and from all walks of life. Several long-term patients in Guatemala trust him as their own primary care physician or internal medicine specialist. For highly-sophisticated internal surgeries or a dietary consultation, he accepts all forms of insurance and can adjust billing for those who need it.

“The best testimonial of continuing success”, says Dr Poole, “is that the patients keep coming back, and refer their friends too.”

Charity, Public Service, Donations

Public service and caring for the less fortunate is a way of life in the Latin culture

Dr. Poole’s medical talent, organizational skills, and generous heart compel him to contribute his time and energy to creating a new family clinic medical center for village residents near Tecpan, Guatemala. For some patients who live far away from the city, medical care is non-existent or of sub-standard quality. Dr. Poole draws from his extensive experience at the largest public hospital in the country, to helping the less fortunate who might not have easy access to prompt and efficient medical attention.

“San Juan de Dios” public hospital, in the historic district of Guatemala City, is well known to all Guatemalans as the general hospital for patients who need to depend on the generosity of social services to diagnose and treat them at a price they can afford.
