In critically ill patients with gallbladder stones and cholecystitis, percutaneous gallbladder drainage serves as a temporizing procedure, palliating the gallbladder-related sepsis. Compared with surgery in critically ill patients, percutaneous drainage has a relatively low complication rate and is rapidly effective. We report our institution s experience in using percutaneous cholecystostomy tube (PCT) insertion as a temporizing measure prior to laparoscopic cholecystectomy. Design: A retrospective study on prospectively collected data Settings: Tertiary care center in Riyadh, Saudi Arabia Subjects: Patients who underwent PCT insertion for acute cholecystitis Intervention: PCT insertion Main outcome measure(s): Clinical picture of the patient, hospital stay and sepsis indicators Results: A total of 5 patients underwent a PCT insertion for acute cholecystitis. Clinical improvement of the patients symptoms (right upper quadrant pain and fever) and normalization of white blood cells following the insertion of the PCT was achieved in 66 hours.75 days (range : - 7 days). The mean hospitalization time was 5. days and the median was 5 ( ) days. All patients subsequently underwent laparoscopic cholecystectomy without conversion nor common bile duct injury in our series. Conclusion: PCT insertion followed by laparoscopic cholecystectomy is an effective and safe treatment in patients with acute cholecystitis and concomitant comorbidities. KEYWORDS: acute care, emergency surgery, empyema, gallbladder, gallstone disease INTRODUCTION Eleven to 0% of patients with symptomatic gall stones present with acute cholecystitis [,]. Although the laparoscopic approach was initially contraindicated, owing to experience, the application of laparoscopic surgery has extended to the treatment of patients with acute cholecystitis. Notably, laparoscopic cholecystectomy has similar operation times, shorter hospital stay and smaller complication rates compared to that of the open technique [,]. The conversion rate of laparoscopic cholecystectomy for acute cholecystitis has been reported to range from % to % [,5], which is significantly higher than the rate reported for elective laparoscopic cholecystectomy (less than 5%) [5]. With conversion, not only is the advantage of this minimally invasive procedure lost, but the cost and complication rates are also increased []. In critically ill patients with gallbladder stones and cholecystitis, percutaneous gallbladder drainage serves as a temporizing procedure, palliating the gallbladderrelated sepsis while the underlying critical conditions are treated. Subsequently, surgery can be performed semi- electively. Compared with surgery in critically ill patients, percutaneous drainage has a relatively low complication rate and is rapidly effective [6].

96 Percutaneous Cholecystostomy Tube in Acute Cholecystitis: Our Experience in a Tertiary Center... June 0 Percutaneous Cholecystostomy Tube (PCT) placement PCT insertion was performed in critically ill patients with strong clinical and imaging evidence of acute cholecystitis who were deemed unfit to undergo immediate surgery (Table ). Acute cholecystitis was diagnosed based on both the clinical and radiological picture. All of our patients were kept in fasting and broad-spectrum IV antibiotics were administered as part of their initial managment. Percutaneous cholecystostomy technique PCT insertion was performed under sterile conditions using intravenous sedation and local anesthesia with % lidocaine hydrochloride. The procedure was performed using ultrasound (US) guidance in 0 patients. Adequate visualization of the gallbladder using US was not possible in patients, who then underwent PCT insertion under computerized tomography (CT) scan guidance. Additionally, patients underwent cholecystostomy tube placement intra-operatively. An -F pigtail catheter was placed into the gallbladder using a single step technique via a transhepatic or transperitoneal approach. PCT was considered technically successful when the pigtail catheter was visualized sonographically in the gallbladder lumen and the gallbladder contents could be aspirated freely through the PCT. All patients had their vital signs monitored and were observed for symptoms of local pain or shoulder discomfort upto four hours after the procedure. RESULTS Demographics and pre-operative status There were 7 males and females. Mean patient age was 5.56 years (range 0-0 years) (Table ). The diagnosis of acute cholecystitis was made in all patients on the basis of clinical and radiological findings (Table ). The most common symptoms were right upper quadrant pain in 5 patients (00%), vomiting in patients (6%), nausea in patients (%), and fever in patients (%) (Table ). While the most common sign was right upper quadrant tenderness in patients (9%), patients (%) also presented with fever (temperature > C), and a palpable mass in patients (%). Eighteen patients (7%) had leukocytosis (Table ). None of the patients developed gallstone pancreatitis. Associated factors were advanced cardiovascular diseases (5, 0%), advanced respiratory diseases (, %), empyema of the gall bladder (5, 0%), unresponsiveness to broad spectrum antibiotics (, %), unclear anatomy intraoperatively (, %), hemodynamic instability (, %), uncontrolled diabetes mellitus (, %), advanced malignancy (, %), and surgeons preference (, %) (Table ). Our radiological studies consisted of abdominal US as the initial confirmatory test for acute cholecystitis, which almost all our patients underwent ( of the 5). The US diagnostic criteria used were the signs of acute inflammation of the gall bladder; this included presence of gall stones, sludge, wall thickening, pericholecystic fluid, sonographic Murphy s sign, and gas in the gallbladder wall (Table ). US was diagnostic of acute cholecystitis in patients (96%), and one patient (%) had his diagnostic US at another institution. Abdominal CT scan was performed in seven patients (%). Hepatobiliary (HIDA) scan was not done for any of our patients. Post-operative outcomes The procedure was successful at the time of insertion of the catheter in all patients. Clinical improvement of the patients symptoms (right upper quadrant pain and fever) and normalization of WBC following the insertion of the PCT was achieved in 66 hours (.75 days on average). All patients showed clinical improvement within a week of tube placement, although notably, the majority (%) improved within days (Table ). Table : Time taken for improvement after PCT insertion (i.e. normal WBC, no fever, no pain) Time till improvement (days) - 7 Number of patients (%) (%) The mean hospitalization time was 5. days, ranging from - days. The majority of patients (%) spent weeks or less in the hospital. While the mean draining duration was 9.67 days, around two thirds of the PCTs drained for a month or less ( patients, 6%). Five PCTs continued to drain for 56 days (0%), whereas a minority continued to drain until an urgent laparoscopic cholecystectomy was performed ( patients, %). Patients were observed daily for early or late complications, including bile peritonitis, bleeding, vagal hypotension and bradycardia, vagal bradycardia alone, respiratory distress and catheter dislodgment. There were no immediate complications. Two patients did have a minor leak, however they did not need any further biliary intervention. Twenty patients (0%) later underwent elective laparoscopic cholecystectomy with no conversion and no common bile duct (CBD) injury, two patients
June 0 KUWAIT MEDICAL JOURNAL 97 (%) had urgent cholecystectomies, one patient (%) had the PCT removed and is being followed up while receiving chemotherapy, one patient (%) died due to a cardiac arrest unrelated to PCT, and one patient (%) was lost to follow up (Fig. ). We didn t encounter any CBD injury nor did we need to convert to an open procedure in any of the operated cases. Cholecystocholangiography was performed prior to the removal of the catheter to visualize the bile tree and gallbladder in patients (%), 0 patients (0%) had a normal flow and two patients (%) had a stone at the cystic duct, while the other patients (5%) did not undergo choelcystocholangiography. PCT was removed in patients (%) after resolution of symptoms and signs, and a nil output from the PCT was observed. Seven patients (%) had PCT removed when the output was nil and the cholecystocholangiography was within normal flow. Three patients (%) had PCT removed with a normal result of cholecystocholangiography regardless of the output. Two patients (%) had the PCT removed intraoperatively. Finally, one patient (%) was lost to follow up with the tube. No complications were faced in the patients (96%) after removal of the PCT, however as aforementioned, one patient (%) was lost to follow up before removal of the PCT. All patients subsequently underwent laparascopic cholecystectomy without conversion or CBD injury in our series. DISCUSSION PCT is an effective, safe, temporizing treatment in patients with acute cholecystitis who have a concomitant co-morbidity that prevents them from undergoing immediate cholecystectomies [7-9]. There is a wide range of reasons for not performing cholecystectomy and thus inserting a PCT instead, but the most common are cardiopulmonary disorders [0]. In rare cases, potentially difficult emergency surgery can be avoided with PCT insertion []. Following PCT insertion, most patients will have resolution of their symptoms [9]. Therefore, cholecystectomy can be performed at a later stage as an elective procedure when the patient s condition has improved []. Drains can be safely removed when drainage has stopped without the need for cholangiography. If drainage continues, then cholangiography needs to be performed. A normal study means PCT can be safely removed []. Laparoscopic cholecystectomy remains the definitive treatment when the patient s condition permits []. CONCLUSION Percutaneous cholecystostomy tube insertion, followed by laparoscopic cholecystectomy, is an effective and safe treatment in patients with acute cholecystitis and concomitant comorbidities. The drains can be safely removed after a nil output reading, or with normal result of a cholangiogram, regardless of the output. This is to be followed by a laparoscopic cholecystectomy in a later elective setting. We have not experienced any conversion procedures nor biliary injuries. However, larger studies are needed to generalize this statement.
