Use of ultrasonographic risk score in the timing of operative intervention for acute cholecystitis

Predictive factors for gangrene complication in acute calculous cholecystitis

Backgrounds/Aims

Gallbladder gangrene is a grave complication of acute calculous cholecystitis that is difficult to detect preoperatively. Ultrasound could show a gallbladder wall that is more thickened. In addition, other clinical measures were reported to be possible predictive factors. Therefore, we aim in this study to evaluate the gallbladder wall thickness measured by ultrasound and other clinical measures as predictive factors for gangrene complication in acute calculous cholecystitis.

Methods

A prospective cohort database analysis of the results of 674 patients diagnosed and treated for acute calculous cholecystitis between January 2010 and December 2014 was done. Patient's inclusion criteria were acute calculous cholecystitis in adults who were operated within three days of onset of symptoms.

Results

117 (17.4%) patients had gangrene. Gallbladder sonographic wall thickness 5.1–6 mm, more than 6 mm, male gender, diabetes mellitus, leukocytosis >15,000 cells/ml, and age ≥40 years were found to be factors predisposing to gangrene complicated acute calculous cholecystitis that represented a statistically significant difference (p≤0.01).

Conclusions

We conclude that gallbladder sonographic wall thickness 5.1–6 mm, more than 6 mm, male gender, diabetes mellitus, leukocytosis >15,000 cells/ml, and age ≥40 years were found to be factors predisposing to gangrene complicated acute calculous cholecystitis that represented a statistically significant difference. By implementing these risk factors, patients urgency for surgery can be decided in the emergency department. Other risk factors such as high alanine aminotransferase, elevated aspartate aminotransferase, and high alkaline phosphatase could be of help in the decision for early operation.

Significance and clinical applications of ultrasound score in assessing the clinical severity of acute cholecystitis in the elderly

OBJECTIVE

To investigate the feasibility and significance of the clinical application of ultrasound score in assessing the clinical severity of acute cholecystitis in the elderly.

METHODS

Pre-surgery ultrasonography was performed on 72 elderly patients with acute cholecystitis who were scheduled for cholecystectomy to determine the score based on ultrasonic imaging features to reflect clinical severity. Prior to operation, the cases were classified as mild, moderate, and severe according to clinical manifestation. The significance of ultrasonography for the prediction of the severity of acute cholecystitis and its pre-surgery guidance were evaluated based on intraoperative findings and postoperative pathology.

RESULT

In the aspect of clinical severity, of the 72 cases, 36 were mild, 21 were moderate, and 15 were severe. The cases that showed enlarged gallbladders, thickened gallbladder walls, double-layer images, gallbladder stones, incarcerated gall-stones, echoes in gallbladder fluid, peri-gallbladder effusions, or adherences were mostly moderate and severe cases. The difference in these cases with the mild cases exhibited statistical significance (P < 0.05). Of the 28 cases that scored ≤5, 26 (92.68 %) were mild cases. The 26 cases that scored between 6 and 9 mainly consisted of 15 moderate cases (57.7 %). The 18 cases that scored ≥10 mainly consisted of 13 severe cases (72.2 %). Significant differences were found in the cholecystostomy cases among the three groups (P < 0.05).

CONCLUSION

Prior to cholecystectomy, ultrasound score could accurately determine the severity of acute cholecystitis in the elderly and may be used as a reference for surgical intervention timing and mode selection to guide clinical therapy.

Acute gallstone cholecystitis in the elderly: treatment with emergency ultrasonographic percutaneous cholecystostomy and interval laparoscopic cholecystectomy

BACKGROUND

The treatment of acute cholecystitis in the elderly is still a subject of debate, particularly with reference to the timing of surgery and the role of laparoscopy.

PATIENTS

From January 1994 to June 2002 we observed 27 patients aged over 70 years with acute calcolous cholecystitis. The patients were submitted to ultrasonographic percutaneous cholecystostomy within 12 h of the acute attack. For two patients (7.4%) at high operative risk, we chose a conservative treatment. Twenty-five patients (92.6%) were submitted, in 15 cases (60%) within 5 days and in 10 patients (40%) within 8 days, to a laparoscopic cholecystectomy. Statistical significance was accepted when the value of p was less than 0.05.

RESULTS

Ultrasonographic percutaneous cholecystostomy was performed successfully in all patients, without major morbidity or mortality, and complete resolution of clinical symptoms was obtained within 48 h. The conversion rate of laparoscopy was 20% (13.3% in patients submitted to surgery within 5 days and 30% in the group submitted within 8 days--p > 0.05). The postoperative morbidity rate was 24%; it was higher (40% versus 15%) in patients converted to laparotomy (p > 0.05); mortality was 4%. The period of hospitalization was 11 days in patients operated laparoscopically and 21 days in those converted to open cholecystectomy (p < 0.001).

CONCLUSIONS

The more rational treatment of acute calcolous cholecystitis in elderly patients is represented by ultrasonographic percutaneous cholecystostomy followed, within 5 days, by laparoscopic cholecystectomy using an abdominal insufflation maximum to 12 mmHg and a limited 10-15 degrees head-up tilt.

Application of trocar technique in ultrasound-guided drainage of the gallbladder

OBJECTIVE

The ultrasound-guided drainage of the gallbladder (USDGB) is mainly performed by Seldinger technique. We aim to evaluate the use of the easier performable trocar technique in draining critically ill patients with acute calculous or acalculous cholecystitis.

PATIENTS AND METHODS

Critically ill patients with acute acalculous (AAC; n=29) or calculous cholecystitis (ACC; n=7) underwent trocar technique application of USD. Technical problems, complications and patients' further courses were recorded.

RESULTS

In group 1 (AAC) 29/29 patients could be drained without problems or complications. Three dislocations of the USDGB were seen. In group 2 (CAC) only four out of seven could be drained by this technique, in these four patients (a) major bleeding and (b) pericholecystic fluid collections were observed. In both groups no further complications during USDGB or its removal were seen.

CONCLUSIONS

In acute acalculous cholecystitis the use of trocar technique in applying the USDGB is easy and bedside performable, in acute calculous cholecystitis the USD should be done by Seldinger technique.

Acute cholecystitis: ultrasonographic staging and percutaneous cholecystostomy

Experience in the treatment of acute cholecystitis with percutaneous cholecystostomy in 29 high-risk and elderly patients is reported. The treatment group included 14 men and 15 women, 21 of whom were over 70 years of age. The suspected clinical diagnosis of acute cholecystitis was confirmed in all cases by ultrasonography (accuracy: 95.6%). The percutaneous cholecystostomy was successful in 27 of 29 cases and these patients had a sudden improvement in their clinical condition; failure of the procedure was due in one patient to dislodgement of the catheter and in another patient to the guide-wire slipping out of the gallbladder. Six patients complained of pain radiating to the right shoulder which disappeared within 30-60 minutes after the procedure. Twenty-three of the 27 patients subsequently underwent elective cholecystectomy. In 22 patients the ultrasonographic findings were compared with the histology; thus enabling us to establish an ultrasonographic staging of acute cholecystitis related to the seriousness of the disease. Percutaneous cholecystostomy is the treatment of choice in high-risk patients, in the elderly, as well as in young patients with impending perforation.

Changing trends in surgery for acute cholecystitis

Surgery for acute cholecystitis has become the most frequent abdominal surgery in most hospitals, yet aspects of its management remain controversial. The aim of this study was to focus on the recent trends by demonstrating the principal differences between 2 series of patients operated on during 10-year intervals. Two hundred fifty-six consecutive operations for acute cholecystitis were performed from 1970 to 1977 (group O) and were compared to 260 cases operated from 1980 to 1987 (group N). Thirty-six variables were recorded in each case. All data obtained were computer recorded and analyzed. Several trends were observed in group N: 1. The population was significantly older with a higher proportion of males and diabetics. 2. There was a marked increase in common bile duct stones, acalculous cholecystitis, and gangrenous changes in the gallbladder. 3. There was a significant increase in patients operated on within 48 hours of admission. 4. There was a significant increase in the number of patients without previous history of biliary symptoms. 5. There was a significant decrease in the rate of wound infections and no statistically significant differences in mortality (N: 3.0%, O: 2.7%). 6. A decrease of the average postoperative hospital stay of 3.2 days was observed. In spite of the older and sicker population in group N, no significant increase in mortality occurred and the postoperative hospital stay was reduced.
