Dr. Mario Antonio García López

Dr. Mario Antonio García López is a senior general surgeon at Hospital Centro Médico, one of Guatemala City's established private hospitals serving both local and international patients. With 18 years of surgical practice and the distinction of Fellowship in the American College of Surgeons (FACS), he brings internationally recognised surgical standards to Guatemala's private healthcare sector. His practice spans the full breadth of general surgery, with particular expertise in minimally invasive laparoscopic techniques, bariatric surgery for obesity management, and colorectal surgery for benign and malignant disease. Dr. García López trained in Guatemala and completed advanced surgical fellowships in the United States and Colombia, giving him direct exposure to high-volume laparoscopic and bariatric programmes that have shaped his technical approach. He is bilingual in Spanish and English, and his FACS credential is widely respected as a benchmark of surgical training and ethical practice. He is an active member of the Asociación Guatemalteca de Cirugía and the Federación Latinoamericana de Cirugía, contributing to surgical education and quality standards across the region.

Dr. García López completed his medical degree at the Universidad Francisco Marroquín in Guatemala City, followed by a surgical residency at a major Guatemalan referral hospital where he received comprehensive training in open and laparoscopic surgical techniques. He subsequently undertook a fellowship in minimally invasive and bariatric surgery at a centre in the United States, gaining experience in high-volume laparoscopic cholecystectomy, advanced laparoscopic hernia repair, sleeve gastrectomy, and Roux-en-Y gastric bypass. He completed additional training in colorectal surgery in Colombia, reinforcing his skills in elective and emergency colorectal procedures including colectomy, low anterior resection, and stoma management. Dr. García López was elected a Fellow of the American College of Surgeons (FACS) following peer review of his training, practice standards, and ethical conduct — a credential that places him among a select group of surgeons in Central America to hold this international recognition. He continues his professional development through the annual congresses of the Federación Latinoamericana de Cirugía and through participation in surgical skills courses in Guatemala and abroad.

Dr. García López's operative expertise is centred on laparoscopic and open general surgical procedures with a strong focus on minimising patient recovery time and surgical risk. He performs laparoscopic cholecystectomy for symptomatic gallstone disease, a procedure he undertakes in both elective and semi-urgent contexts with consistently low complication rates. He manages acute appendicitis with laparoscopic appendectomy, offering patients a minimally invasive approach with rapid return to normal activity. His hernia repair experience encompasses inguinal, femoral, umbilical, incisional, and hiatal hernias, using both laparoscopic and open techniques with prosthetic mesh where appropriate. In colorectal surgery, he performs resections for colorectal cancer, diverticular disease, inflammatory bowel disease, and benign anorectal conditions, with experience in laparoscopic colectomy and sphincter-preserving rectal surgery. His bariatric surgery practice includes laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass for eligible patients with obesity, combined with a structured pre- and post-operative programme addressing nutrition, behaviour, and follow-up. For abdominal malignancies, he works within a multidisciplinary oncology framework at Hospital Centro Médico, performing curative and palliative surgical resections as part of coordinated cancer care.

Dr. García López has contributed to surgical research addressing outcomes in laparoscopic surgery and bariatric procedures in the Guatemalan and Central American patient population. He has presented case series on laparoscopic cholecystectomy outcomes and complications at national surgical congresses, and has contributed data on bariatric surgery results — including weight loss outcomes and resolution of obesity-related comorbidities — to regional registries coordinated through the Federación Latinoamericana de Cirugía. He is involved in surgical quality improvement initiatives at Hospital Centro Médico, including audit of perioperative complication rates and adherence to enhanced recovery after surgery (ERAS) protocols. He also participates in surgical education, providing training in laparoscopic techniques to surgical residents and junior surgeons through workshops in Guatemala City.

Hospital Centro Médico in Guatemala City caters to an international patient base, and Dr. García López is well positioned to manage overseas patients seeking general surgery procedures at significantly lower cost than in North America or Europe. Commonly sought procedures from international patients include laparoscopic cholecystectomy, hernia repair, and bariatric surgery. Dr. García López conducts pre-operative video consultations for patients travelling from abroad, reviews imaging and medical records sent in advance, and provides comprehensive post-operative documentation and follow-up guidance for patients returning to their home country. His fluency in English facilitates direct communication with patients and their overseas medical teams. Guatemala City is served by La Aurora International Airport with direct connections to major North American hubs, and Hospital Centro Médico is located in a central urban district with convenient access to accommodation.

Dr. García López's election as a Fellow of the American College of Surgeons (FACS) is his most prominent professional distinction, representing an internationally peer-reviewed credential that affirms his surgical training, competence, and ethical standards. He has been recognised by the Asociación Guatemalteca de Cirugía for his contributions to advancing minimally invasive surgical practice in Guatemala and for his role in surgical education. His participation in the Federación Latinoamericana de Cirugía reflects his standing in the broader Latin American surgical community. Hospital Centro Médico has acknowledged his contribution to building the hospital's bariatric surgery programme, which has expanded access to weight loss surgery for Guatemalan patients and medical tourists from across Central America.
