The aim of this study was the detection of criteria that support the indication for laparoscopic adhesiolysis in patients presenting with unspecific symptoms. A prospective analysis investigates the value of laparoscopic adhesiolysis in patients with chronic abdominal pain after exclusion of other pathologic findings; 58 consecutive patients were followed after laparoscopic adhesiolysis. Endpoints of investigation were extent of adhesions, complications, postoperative hospitalization, and postoperative quality of life. A comparison was drawn to patients following laparoscopic cholecystectomy, laparoscopic cholecystectomy plus adhesiolysis, and conventional cholecystectomy. The results showed that major complications occurred in 10% of cases. In 45% of patients we found a complete remission, in 35% a substantial improvement, and in 20% a persistence of complaints. In a correlation between the preoperative complaints and the extent of adhesions we found small adhesions to cause recurrent abdominal pain without other symptoms while large adhesions produce recurrent abdominal pain in combination with symptoms indicative of intermittent bowel obstruction. Finally, the results of this study indicate a certain "ideal constellation" for an enduring successful adhesiolysis per laparoscopy: it is the subjective complaint of recurrent abdominal pain with a localized and reproducible punctum maximum in combination with a circumscribed area of adhesions at that site.

Anorectal manometry has only limited diagnostic value; although rather exact quantifications of individual parameters can be achieved, the impact of these measurements should be regarded rather critically, since only SL and RP appeared to be reproducible parameters.

OBJECTIVE . We assessed the value of sonography in predicting intraoperative difficulties for patients undergoing laparoscopic cholecystectomy and in identifying indicators for conversion to conventional cholecystectomy. SUBJECTS AND METHODS . Upper abdominal sonography was performed (according to a checklist) in 75 consecutive patients before laparoscopic cholecystectomy. Sonographic findings were verified by the surgeon in the operating room.RESULTS . Conversion from laparoscopic surgery to laparotomy was performed in five patients (6.7%). Of 75 patients, 19 had sonograms revealing gallbladder wall thickening (>4 mm); surgical preparation difficulties in 16 of these patients led to laparotomy in four patients. Sensitivity, specificity, positive predictive value, and accuracy of wall thickening as an indicator of technical difficulties were 66.7%, 94.1%, 84.2%, and 85.3%, respectively. Sensitivity, specificity, positive predictive value, and accuracy of wall thickening as an indicator of surgical conversion were 80.0%, 78.6%, 21.1%, and 78.7%, respectively. Technical difficulties at laparoscopy occurred in all five patients with pericholecystic fluid on sonography (sensitivity, 20.8%; specificity, 100%; positive predictive value, 100%; accuracy, 74.7%) and led to laparotomy in three patients (sensitivity 60.0%, specificity 97.1%, positive predictive value 60%, accuracy 94.7%). The accuracy of sonography for cholecystolithiasis was 100%.CONCLUSION . On sonography, gallbladder wall thickening is the most sensitive indicator and pericholecystic fluid is the most specific indicator of technical difficulties during laparoscopic cholecystectomy. Such difficulties may require conversion to laparotomy.
