Current practice in the management of acute cholecystitis

Outcomes of Consistent Conservative Management for Acute Cholecystitis Followed by Delayed Cholecystectomy

OBJECTIVE

This study's objective was to assess outcomes of a totally conservative strategy for acute cholecystitis (AC) followed by delayed elective cholecystectomy.

PATIENTS AND METHODS

Consecutive patients who underwent cholecystectomy for AC were divided into the Emergent and Elective cholecystectomy groups. Patients in the elective cholecystectomy group were divided into early, medium, and late groups according to time from symptoms onset.

RESULTS

The success rate for conservative management reached 97.2%. Increased blood loss and a higher conversion rate were significantly associated with the emergent group. Patients in the late group had significantly lower operative time and tended to have lower blood loss and less frequent conversion to open surgery than those in the early and medium groups.

CONCLUSIONS

Most AC cases could be managed conservatively, and elective cholecystectomy was performed safely regardless of the time. Elective cholecystectomy carried out in late phase was likely to be associated with decreased surgical difficulty.

Mortality associated with the treatment of gallstone disease: a 10-year contemporary national experience

BACKGROUND

Gallstones remain a common clinical problem requiring skilled operative and nonoperative management. The aim of the present population-based study was to investigate causes of gallstone-related mortality in Scotland.

METHODS

Surgical deaths were peer reviewed between 1997 and 2006 through the Scottish Audit of Surgical Mortality (SASM); data were analyzed for patients in whom the principal diagnosis on admission was gallstone disease.

RESULTS

Gallstone disease was responsible for 790/43,271 (1.83%) of the surgical deaths recorded, with an overall mortality for cholecystectomy of 0.307% (176/57,352), endoscopic retrograde cholangiopancreatography (ERCP) of 0.313% (117/37,345), and cholecystostomy of 2.1% (12/578) across the decade. However, the majority of patients who died were elderly (47.6% ≥ 80 years or older) and were managed conservatively. Deaths following cholecystectomy usually followed emergency admission (76%) and were more likely to have been associated with postoperative medical complications (n = 189) than surgical complications (n = 36).

DISCUSSION

Although cholecystectomy is a relatively safe procedure, patients who die as a result of gallstone disease tend to be elderly, to have been admitted as emergency cases, and to have had co-morbidities. Future combined medical and surgical perioperative management may reduce the mortality rate associated with gallstones.

Urgent cholecystectomy for acute cholecystitis in a district general hospital - is it feasible?

INTRODUCTION

Laparoscopic cholecystectomy has become the gold standard for treatment of symptomatic gall stone disease. However, its place remains controversial in the management of acute cholecystitis due to a high reported incidence of bile leaks and conversion rate. Tertiary referral centres have reported good results. We present a series of cases after the introduction of an urgent cholecystectomy pathway in a district general hospital.

PATIENTS AND METHODS

A practice of urgent cholecystectomy for acute cholecystitis was introduced by three consultant general surgeons. All prospective patients having an urgent laparoscopic cholecystectomy for acute cholecystitis, over an 8-month period were entered into a database. A dedicated ultrasound service was instituted to provide prompt diagnosis in these patients. Their demographic details, operative findings, laboratory results were recorded in a prospective database. Timing of ERCP, postoperative complications and conversion rate and hospital stay were also noted.

RESULTS

There were 64 patients in the study with a median age of 51 years (range, 21-84 years). There were 21 males and 43 females. All patients underwent laparoscopic cholecystectomy during the index admission. Eleven patients had pre-operative ERCP and 12 patients had on-table cholangiogram. There were no conversions. Postoperative ERCP was required in six patients. The median time interval between admission and operation was 3 days (range, 2-7 days). There were two bile leaks but no common bile duct injury. There were two cases of superficial wound infection. One patient required re-operation for small bowel obstruction secondary to a port site hernia.

CONCLUSIONS

Urgent laparoscopic cholecystectomy for acute cholecystitis is a feasible treatment option in a district general hospital. A safe practice can be ensured by adherence to a care pathway and a multidisciplinary, consultant-delivered service. Urgent cholecystectomy service can be provided safely in a district general hospital with outcomes comparable to previously published literature.

Need for criteria for the diagnosis and severity assessment of acute cholangitis and cholecystitis: Tokyo Guidelines

The Tokyo Guidelines formulate clinical guidance for healthcare providers regarding the diagnosis, severity assessment, and treatment of acute cholangitis and acute cholecystitis. The Guidelines were developed through a comprehensive literature search and selection of evidence. Recommendations were based on the strength and quality of evidence. Expert consensus opinion was used to enhance or formulate important areas where data were insufficient. A working group, composed of gastroenterologists and surgeons with expertise in biliary tract surgery, supplemented with physicians in critical care medicine, epidemiology, and laboratory medicine, was selected to formulate draft guidelines. Several other groups (including members of the Japanese Society for Abdominal Emergency Medicine, the Japan Biliary Association, and the Japanese Society of Hepato-Biliary-Pancreatic Surgery) have reviewed and revised the draft guidelines. To build a global consensus on the management of acute biliary infection, an international expert panel, representing experts in this area, was established. Between April 1 and 2, 2006, an International Consensus Meeting on acute biliary infections was held in Tokyo. A consensus was determined based on best available scientific evidence and discussion by the panel of experts. This report describes the highlights of the Tokyo International Consensus Meeting in 2006. Some important areas focused on at the meeting include proposals for internationally accepted diagnostic criteria and severity assessment for both clinical and research purposes.

Impact of treatment policies on patient outcomes and resource utilization in acute cholecystitis in Japanese hospitals

Background

Although currently available evidence predominantly recommends early laparoscopic cholecystectomy (LC) for the treatment of acute cholecystitis, this strategy has not been widely adopted in Japan. Herein, we describe a hospital-based study of patients with acute cholecystitis in 9 Japanese teaching hospitals in order to evaluate the impact of different institutional strategies in treating acute cholecystitis on overall patient outcomes and medical resource utilization.

Methods

From an administrative database and chart review, we identified 228 patients diagnosed with acute cholecystitis who underwent cholecystectomy between April 2001 and June 2003. In order to examine the relationship between hospitals' propensity to perform LC and patient outcomes and/or medical resource utilization, we divided the hospitals into three groups according to the observed to expected ratio of performing LC (LC propensity), and compared the postoperative complication rate, length of hospitalization (LOS), and medical charges.

Results

No hospital adopted the policy of early surgery, and the mean overall LOS among the subjects was 30.9 days. The use of laparoscopic surgery varied widely across the hospitals; the adjusted rates of LC to total cholecystectomies ranged from 9.5% to 77%. Although intra-operative complication rate was significantly higher among patients whom LC was initially attempted when compared to those whom OC was initially attempted (9.7% vs. 0%), there was no significant association between LC propensity and postoperative complication rates. Although the postoperative time to oral intake and postoperative LOS was significantly shorter in hospitals with high use of LC, the overall LOS did not differ among hospital groups with different LC propensities. Medical charges were not associated with LC propensity.

Conclusion

Under the prevailing policy of delayed surgery, in terms of the postoperative complication rate and medical resource utilization, our study did not show the superiority of LC in treating acute cholecystitis patients. The timing of surgery and discharge was mainly determined by the institutional policy in Japan, rather than by the clinical course of the patient; however, considering the substantially less postoperative pain and shorter recovery time of LC compared to OC, LC should be actively applied for the treatment of acute cholecystitis. If the policy of early surgery were universally applied, the advantage of LC over OC may be more clearly demonstrated.
