Abstract
PURPOSE: In a previous, prospective, randomized study of the use of nasogastric tubes in patients undergoing elective abdominal colorectal surgery, we found that patients who did not have nasogastric (NG) decompression postoperatively had a significantly higher rate of abdominal distention, nausea, and vomiting. Patients from that study have now been followed for a median duration of 5.3 years to evaluate whether this elevation in perioperative intra-abdominal pressure would subsequently lead to an increased incidence of incisional hernia. RESULTS: Of the 251 patients who received NG decompression, 8 (3.2 percent) developed incisional hernias compared with 15 (6.6 percent) of 229 patients who were not decompressed (P=0.085). CONCLUSIONS: The increase in postoperative abdominal distention and vomiting that occurs in patients who do not receive NG decompression does not lead to a significantly increased incidence of incisional hernia. Furthermore, we continue to support avoidance of routine prophylactic post-operative nasogastric decompression in uncomplicated, elective abdominal colorectal surgery.
