Procedure Overview
Resection in the endocrine system means the complete surgical removal of a gland such as the thyroid, a parathyroid gland, an adrenal gland, or the pituitary, without any replacement structure put in its place. It is one of the most frequently performed procedures in endocrine surgery because so many endocrine conditions, from cancer to hormone-secreting tumors to autoimmune overactivity, are best treated by taking the entire gland out.
Common reasons include thyroid cancer or a large multinodular goiter, Graves' disease that has not responded to medication, a parathyroid adenoma causing hyperparathyroidism, an adrenal tumor such as a pheochromocytoma, or a pituitary tumor removed through the skull base. Because these glands regulate metabolism, blood pressure, calcium balance, and stress hormones, patients undergoing resection typically need lifelong hormone replacement or monitoring afterward, which their care team discusses well before surgery.
Anatomy & Axis Detail
Superior Parathyroid Gland, Right
The right superior parathyroid gland is one of typically four small, hormone-producing bodies embedded in or near the posterior surface of the thyroid, regulating calcium through parathyroid hormone secretion. Its resection is performed when this specific gland is identified as hyperfunctioning, commonly due to a solitary adenoma causing primary hyperparathyroidism, and preoperative localization studies such as sestamibi scanning or ultrasound help the surgeon target this gland specifically rather than exploring all four. Because superior glands are usually found in a more consistent anatomic position than inferior ones, dissection can often be more limited, but intraoperative parathyroid hormone monitoring is frequently used to confirm that removing this single gland has corrected the excess hormone level before closing.
Approach: Percutaneous Endoscopic
Percutaneous Endoscopic combines a puncture through skin or mucous membrane with insertion of an endoscope to visualize the procedure internally, as in laparoscopic cholecystectomy. It is distinguished from plain Percutaneous by the presence of scope-guided visualization, and from Via Natural or Artificial Opening Endoscopic by its route being a new puncture rather than an existing orifice or stoma.
Coding & Documentation
The operative report must confirm the entire gland was removed, not a lobe, nodule, or partial gland, since a partial removal is coded as excision instead. When a total thyroidectomy is performed in stages or as completion surgery after a prior partial removal, coders need to check whether any residual tissue remained from the earlier operation and code accordingly. A common mistake is coding bilateral adrenalectomy or parathyroidectomy as a single procedure when each gland is a separate body part value requiring its own code. Coders should also watch for cases where a resection is combined with a separate reconstructive or reconstructive-adjacent step, such as autotransplantation of a parathyroid gland fragment, which requires an additional code.
