[2][3] He earned a Ph.D. in Medical Sciences in October 1926 with the presentation of the thesis Autoseroterapia de los derrames (Auto-serum therapy of effusions) and then devoted himself largely as a teacher.
He considered diagnosis an art that had to be accomplished not only through clinical history, but through long, sustained, conversation with the patient about their health problems and living conditions.
Beginning in 1936, he conducted research and descriptions on colorectal pericolonic appendicular syndrome caused by parasites, and eight years later presented a paper on this topic at the National Academy of Medicine, the importance of which focused on developing a surgical treatment for the disease.
In Venezuela he did a series of interventions including pasacro nerve resection in the treatment of pelvic neuralgia, resection of the rectum with contra natura permanent anum, (1932), ovarian homografts (1936), the new technique of lymphatic blockade in infectious processes, carried out with electrosurgery linked with sulfonamide therapy (1938), the radical cure of rectal prolapse with fascia lata (aponeurosis of the thigh) ligation of the femoral artery by gangrene and embolectomy by phlebitis.
He also contributed to improving the treatment of Banti syndrome (abnormal growth of the spleen) and portal hypertension (usually caused by liver cirrhosis).
