Colorectal Surgery

Colorectal Surgery

Colorectal Surgery focuses on operative care of the colon, rectum, and anus, treating conditions such as cancer, diverticulitis, inflammatory bowel disease, polyps, fistulas, hemorrhoids, and pelvic floor disorders. CSTs in colorectal surgery support open, laparoscopic, robotic, and transanal procedures that require strong anatomical knowledge, precise instrument handling, and the ability to manage complex abdominal and pelvic workflows. This specialty demands expertise in bowel technique, anastomosis support, and sterile handling of contaminated fields.

Role of CSTs

  • Prepare colorectal instrument sets, laparoscopic tools, and robotic equipment for colon, rectal, and anal procedures.
  • Assist with patient positioning for abdominal, lithotomy, or lateral approaches.
  • Maintain sterile technique during procedures involving bowel, contamination risk, and multi‑quadrant access.
  • Anticipate surgeon needs during dissection, mobilization, resection, and anastomosis.
  • Manage stapling devices, energy platforms, and transanal access systems.
  • Support robotic workflows for rectal cancer, low anterior resection, and pelvic dissection.
  • Handle specimens including bowel segments, polyps, lymph nodes, and biopsies with accurate labeling.
  • Assist with counts, irrigation management, and efficient turnover during long, multi‑stage cases.

Essential Skills

  • Strong understanding of colorectal and pelvic anatomy.
  • Proficiency with laparoscopic, open, and robotic colorectal instruments.
  • Ability to anticipate surgeon needs during bowel mobilization and anastomosis.
  • Skilled in handling staplers, energy devices, and bowel clamps.
  • Competence with contaminated‑field sterile technique and isolation methods.
  • Ability to maintain an organized field during long pelvic procedures.
  • Effective communication with surgeons, anesthesia, and nursing teams.
  • Familiarity with ERAS‑aligned workflows and specimen handling.

Common Procedures

  • Colectomy (right, left, sigmoid)
  • Low anterior resection (LAR)
  • Abdominoperineal resection (APR)
  • Hemorrhoidectomy
  • Fistula and fissure repair
  • Transanal minimally invasive surgery (TAMIS/TEMS)
  • Robotic rectal cancer surgery
  • Diverticulitis resection
  • Stoma creation or reversal
  • Bowel obstruction surgery
  • Polypectomy (surgical)
  • Pelvic floor reconstruction

Instruments & Equipment

Instruments

  • Major colorectal sets (open and laparoscopic)
  • Bowel clamps (Doyen, Glassman)
  • Linear and circular staplers
  • Energy devices (LigaSure, Harmonic, monopolar, bipolar)
  • Transanal access platforms (TAMIS/TEMS)
  • Retractors (Bookwalter, Omni‑tract, Lone Star)
  • Robotic colorectal instruments
  • Specimen retrieval bags
  • Suction/irrigation and smoke evacuation tools

Equipment

  • Laparoscopic towers and insufflation units
  • Robotic surgical platforms
  • Electrosurgical generators
  • Suction and irrigation systems
  • Positioning devices for lithotomy and low pelvic access
  • Endoscopic visualization tools for transanal procedures
  • Warming devices and fluid warmers

Workflow & Case Progress

  1. Room setup with colorectal instruments, staplers, energy devices, and imaging equipment.
  2. Patient positioning based on abdominal or pelvic access.
  3. Prepping and draping with attention to contamination control.
  4. Initial access via laparoscopic, robotic, transanal, or open approach.
  5. Mobilization of bowel and identification of pathology.
  6. Resection of diseased segment and preparation for anastomosis.
  7. Anastomosis creation using staplers or suturing techniques.
  8. Leak testing, hemostasis, and specimen handling.
  9. Closure of incisions or trocar sites.
  10. Final counts and transfer to PACU with detailed handoff.

Sterile Technique Considerations

  • Maintain strict isolation technique during contaminated bowel cases.
  • Protect the sterile field during laparoscopic tower or robotic arm adjustments.
  • Handle staplers and anastomotic devices without contaminating the field.
  • Maintain sterile technique during long pelvic dissections with limited space.
  • Manage multiple trays and fluid‑heavy environments efficiently.
  • Ensure sterile technique during conversions from minimally invasive to open surgery.
