It was Antonie van Leeuwenhoek, the Father of Microbiology, who first observed then described single-celled organisms, which are later called as microorganisms. In fact, with the help of a crude but still useful microscope, he was able to perform bacterial cells observation such as the study the muscle fibers of bacteria, human blood, and spermatozoa.

Clinical Manifestations

Dysphagia (difficulty in swallowing) is the primary symptom of esophageal motor disorders. Its perception by the patient is a bal¬ance between the severity of the underlying abnormality causing the dysphagia, and the adjustment made by the patient in altering eating habits. Consequently, any complaint of dysphagia must include an assessment of the patient’s dietary history. It must be known whether the patient experiences pain, chokes, or vomits with eating: whether the patient requires liquids with the meal, is the last to finish, or is forced to interrupt a social meal; and whether he or she has been admitted to the hospital for food impaction. These assessments, plus an evaluation of the patient’s nutritional status, help to determine how severe the dysphagia is and evaluate the indications for surgical therapy. (more…)

Nissen Fundoplication

The most common antireflux procedure is the Nissen fundoplication. The procedure can be performed through an abdominal or a chest incision, as well as through a laparoscope. Rudolph Nissen described the procedure as a 360-degree fundoplication around the lower esophagus for a distance of 4 to 5 cm. Although this provided good control of reflux, it was associated with a number of side effects that have encouraged modifications of the procedure as originally described. These include using only the gastric fundus to envelop the esophagus in a fashion analogous to a Witzel jejunostomy, sizing the fundoplication with a 60F bougie, and limiting the length of tip fundoplication to 1 to 2 cm. The essential elements necessary for the performance of a transabdominal fundoplication are com¬mon to both the laparoscopic and open procedures and include the following: (more…)

Principles of Surgical Therapy

Compound light microscopes are just examples of microscopes used in the medical field today. These compound light microscopes aid clinicians and surgeons in tissue assessment, magnification and disease diagnosis. Esophageal tissue samples can be sent to the laboratory for biopsy and further studies with the use of compound light microscopes to rule out other differential diagnosis. (more…)

The selection of a curative versus a palliative operation for cancer of the esophagus is based on the location of the tumor, the patient’s age and health, the extent of the disease, and intraoperative staging. A diagnosis of esophageal malignancy is done when tissue samples are studied under compound light microscopes for biopsy. (more…)
