G. Borzellino et al., DETECTION OF ABDOMINAL ADHESIONS IN LAPAROSCOPIC SURGERY - A CONTROLLED-STUDY OF 130 CASES, Surgical laparoscopy & endoscopy, 8(4), 1998, pp. 273-276
The risk of visceral injury during laparoscopy occurs mainly during th
e creation of the pneumoperitoneum and the insertion of the first troc
ar and is substantially greater in patients with a previous history of
laparotomic surgery or peritonitis, owing to the possible presence of
abdominal wall adhesions. In this study we assessed the results of pr
eoperative ultrasonography of the parietal wall for the diagnosis of p
eritoneal adhesions, through the detection of two signs unrelated to o
ne another, for the purpose of minimizing the number of false-negative
results. Ultrasonography of the parietal wall was performed preoperat
ively in 130 patients who had previously undergone laparotomy. The ult
rasound results were transcribed in the form of a map of the abdominal
wall and checked during laparoscopy. The overall diagnostic accuracy
was 88.5%, the specificity was 31.8%, and the sensitivity was 100%. Th
e hazardous laparoscopic maneuvers were performed in adhesion-free are
as in all cases, and there were no cases of complications due to visce
ral injury.
