Our Summary

This research paper is about a new surgical training device called Sigmaster that was created to simulate the sigmoid colon, a part of the human intestine. The device is designed to closely mimic the actual layers and structures found in the body, including blood vessels, nerve sheaths, and intestinal tracts. It is made from dry polyester fibers and has conductivity, which means that energy devices can be used on it. The layer adhesion is adjustable to allow for realistic peeling techniques. This device is used to train surgeons on performing a laparoscopic sigmoidectomy, a minimally invasive surgical procedure that removes part of the colon. The paper compares the results of a simulated surgery using the Sigmaster and an actual surgery.

Doctor’s Tip

One helpful tip a doctor might tell a patient about sigmoidectomy is to follow post-operative care instructions carefully, including taking prescribed medications, eating a healthy diet, and avoiding strenuous activities until fully healed. It is important to attend follow-up appointments with your healthcare provider to monitor your recovery and address any concerns.

Suitable For

Patients who may be recommended for a sigmoidectomy include those with conditions such as diverticulitis, colorectal cancer, inflammatory bowel disease, or a bowel obstruction. Sigmoidectomy may also be recommended for patients with severe or recurring diverticulitis that does not respond to other treatments, or for those with a large polyp or tumor in the sigmoid colon. Additionally, patients with a history of chronic constipation or bowel motility disorders may benefit from a sigmoidectomy to improve their quality of life. It is important for patients to discuss their individual medical history and treatment options with their healthcare provider to determine if a sigmoidectomy is the best course of action for their condition.

Timeline

Before sigmoidectomy:

  1. Patient presents with symptoms such as abdominal pain, bloating, constipation, and changes in bowel habits.
  2. Patient undergoes diagnostic tests such as a colonoscopy or CT scan to confirm the presence of a sigmoid colon issue.
  3. Patient consults with a surgeon to discuss treatment options, including the possibility of a sigmoidectomy.
  4. Patient undergoes pre-operative preparations such as fasting, bowel preparation, and medical evaluations.

During sigmoidectomy:

  1. Surgeon performs a laparoscopic sigmoidectomy using the Sigmaster training device to practice the procedure.
  2. Surgeon makes small incisions in the abdomen and removes the affected part of the sigmoid colon.
  3. Surgeon reconnects the remaining parts of the colon and closes the incisions.
  4. Patient is monitored in the recovery room before being transferred to a hospital room for post-operative care.

After sigmoidectomy:

  1. Patient experiences pain, discomfort, and bloating in the abdomen, which is managed with pain medications.
  2. Patient is gradually allowed to resume eating and drinking, starting with clear liquids and progressing to solid foods.
  3. Patient is encouraged to walk and perform breathing exercises to prevent complications such as blood clots and pneumonia.
  4. Patient is discharged from the hospital once they are able to tolerate food, have normal bowel movements, and are free from complications.
  5. Patient follows up with the surgeon for post-operative visits to monitor healing and address any concerns.

What to Ask Your Doctor
