6.6 GI Procedures and Surgical Suffixes
Key Takeaways
- GI procedure terms are built from a body-part root plus a suffix for viewing, incision, opening, removal, repair, or fixation.
- The contrast among -otomy, -ostomy, and -ectomy is essential for digestive and ostomy-related terms.
- Colonoscopy, gastroscopy, appendectomy, colectomy, colostomy, ileostomy, gastrostomy, and anastomosis are high-yield procedure terms.
- Terminology exams often use the correct organ with the wrong suffix as a distractor, so define the action before choosing.
GI Procedures and Surgical Suffixes
Digestive procedure terms reward careful suffix reading. A learner may know that gastr/o means stomach and col/o means colon, but the suffix decides whether the term means visual examination, incision, creation of an opening, removal, repair, or fixation. Many wrong answers in medical terminology practice are built from the right root and the wrong action. That is why you should define both parts every time.
Procedure Suffix Core
| Suffix | Meaning | GI example | Plain definition |
|---|---|---|---|
| -scopy | visual examination | colonoscopy | visual examination of the colon |
| -scope | instrument for viewing | gastroscope | instrument used to view the stomach |
| -graphy | process of recording or imaging | cholangiography | imaging of bile ducts |
| -gram | record or image | cholangiogram | image or record of bile ducts |
| -otomy | incision into | gastrotomy | incision into the stomach |
| -ostomy | creation of an opening | colostomy | creation of an opening into the colon |
| -ectomy | surgical removal | appendectomy | removal of the appendix |
| -plasty | surgical repair | pyloroplasty | repair of the pylorus |
| -pexy | surgical fixation | gastropexy | fixation of the stomach |
| -rrhaphy | suturing | herniorrhaphy | suturing or repair of a hernia |
| -anastomosis | surgical connection | enteroenterostomy or anastomosis context | connection between two tubular structures |
-otomy, -ostomy, and -ectomy
These three suffixes deserve special practice. -otomy means incision into. -ostomy means creation of an opening. -ectomy means removal. Gastrotomy is incision into the stomach. Gastrostomy is creation of an opening into the stomach. Gastrectomy is removal of all or part of the stomach. Colotomy is incision into the colon. Colostomy is creation of an opening into the colon. Colectomy is removal of all or part of the colon.
Ostomy terms often refer to surgically created openings that allow waste, feeding, or drainage to pass through a new route. A colostomy creates an opening from the colon to the outside of the body. An ileostomy creates an opening from the ileum. A gastrostomy creates an opening into the stomach, often discussed in feeding tube contexts. A jejunostomy creates an opening into the jejunum. The root tells you where the opening is.
Viewing Procedures
| Term | Roots | Meaning |
|---|---|---|
| gastroscopy | gastr/o + -scopy | visual examination of the stomach |
| colonoscopy | colon/o + -scopy | visual examination of the colon |
| sigmoidoscopy | sigmoid/o + -scopy | visual examination of the sigmoid colon |
| esophagoscopy | esophag/o + -scopy | visual examination of the esophagus |
| esophagogastroduodenoscopy | esophag/o + gastr/o + duoden/o + -scopy | visual examination of the esophagus, stomach, and duodenum |
A scope term may appear in a real procedure that includes biopsy, treatment, or sample collection, but the word-part meaning of -scopy is visual examination. In a pure terminology question, choose the answer that reflects viewing. If the term ends in -gram, think record or image. If it ends in -graphy, think the process of producing a record or image.
Removal and Repair Terms
Appendectomy is removal of the appendix. Colectomy is removal of colon tissue. Gastrectomy is removal of all or part of the stomach. Hemorrhoidectomy is removal of hemorrhoids. Herniorrhaphy is suturing or repair of a hernia, while hernioplasty is surgical repair of a hernia, often with reinforcement depending on context. Pyloroplasty is surgical repair of the pylorus.
Case-Style Decoding
Suppose a question says a patient has a surgically created opening from the ileum to the abdominal wall. The root ile/o points to ileum and -ostomy means creation of an opening, so ileostomy is the best answer. If the question says the appendix was surgically removed, appendectomy is best because -ectomy means removal. If the question says the colon was viewed with a scope, colonoscopy is best because -scopy means visual examination.
Before leaving this section, drill the suffixes without organs. Say incision, opening, removal, repair, visual exam, image, and suturing. Then add roots. This prevents the common mistake of selecting a familiar GI word that names the right body part but the wrong procedure.
