Predictive factors for surgical indication in adhesive small bowel obstruction

Area of Science:

• Gastroenterology
• Surgical Oncology
• Abdominal Surgery

Background:

• Small bowel obstruction (SBO) is a common complication following abdominal surgery.
• Intestinal decompression with a long nasointestinal tube (LT) is a primary treatment, but treatment failure occurs in some patients.

Purpose of the Study:

• To identify predictive factors for LT decompression failure in adhesive SBO.
• To determine the optimal timing for surgical intervention (laparotomy) in cases of non-response.

Main Methods:

• Retrospective analysis of clinical and laboratory data from 53 patients with adhesive SBO.
• Evaluation of factors predicting LT decompression failure.
• Assessment of outcomes for patients undergoing LT decompression versus laparotomy.

Main Results:

• Complete SBO and elevated serum creatine phosphokinase (CPK >or= 130 IU/L) were independent predictors of LT failure.
• Laparotomy was required in 14 patients (26.4%), while 39 patients (73.6%) had successful LT decompression.
• Resolution of SBO took significantly longer in complete SBO (6.3 days) compared to partial SBO (2.6 days).

Conclusions:

• Complete SBO and high CPK levels indicate a higher likelihood of failed LT decompression.
• Laparotomy is advised for complete SBO after 7 days of failed LT decompression and for partial SBO after 3 days.
