Zorluk: KolayPreoperative and Postoperative Care

On his sixth day of recovery following an open appendectomy for perforated appendicitis, a 65-year-old man reports progressive abdominal bloating and bilious vomiting. He has not passed flatus or stool for the past 48 hours. Vital signs show a heart rate of 110/min and blood pressure of 115/75 mmHg. Physical examination reveals a markedly distended, tympanitic abdomen with high-pitched 'tinkling' bowel sounds. There is diffuse mild tenderness but no rebound or guarding. Arrange the following management steps in the most appropriate chronological sequence for this patient's condition, progressing from initial intervention to definitive management.

  1. 1Initiate strict nil per os (NPO) status and begin intravenous fluid resuscitation.
  2. 2Place a nasogastric tube for gastrointestinal decompression.
  3. 3Obtain a contrast-enhanced computed tomography (CT) scan of the abdomen and pelvis.
  4. 4Proceed to the operating room for an exploratory laparotomy.

Cevap

The correct sequence is: 1) Initiate NPO and IV fluids, 2) Place a nasogastric tube, 3) Obtain a CT scan of the abdomen, and 4) Proceed with an exploratory laparotomy.
The management of an uncomplicated early postoperative small bowel obstruction follows a well-defined progression of care. Initial management focuses on stabilizing the patient by making them NPO and providing intravenous fluid resuscitation to combat hypovolemia from third-spacing. This is immediately followed by nasogastric tube placement to decompress the stomach and prevent aspiration. Once stabilized, a CT scan is obtained to confirm the diagnosis, identify the transition point, and rule out complications like strangulation. Surgical intervention (exploratory laparotomy) is reserved as the final step if conservative management fails after several days or if the patient develops signs of ischemia or peritonitis.

Adım Adım Çözüm

1
Recognize the clinical presentation of an early postoperative small bowel obstruction.
The patient's obstipation, vomiting, distension, and high-pitched bowel sounds confirm the suspected diagnosis.
Accurate identification dictates the subsequent algorithmic management.
2
Prioritize initial stabilization with NPO status and IV fluids.
Intravascular volume is restored and further gastrointestinal input is halted.
Third-spacing of fluids into the bowel lumen leads to significant hypovolemia that must be corrected immediately.
3
Implement mechanical decompression via a nasogastric tube.
Gastric contents and swallowed air are evacuated.
This reduces the risk of aspiration and alleviates patient discomfort.
4
Acquire diagnostic imaging to stratify risk and guide definitive therapy.
A CT scan provides visualization of the bowel wall and transition point.
Imaging differentiates a partial obstruction (which may resolve conservatively) from a complete obstruction or ischemia.
5
Reserve surgical exploration for definitive failure of conservative therapy.
Laparotomy is performed only after conservative measures are exhausted or if complications arise.
Many early postoperative bowel obstructions resolve with supportive care alone; surgery is the final step in the algorithmic pathway.
