Intraabdominal abscess after cholecystectomy: Do not forget the stones

Abstract

Gallbladder perforation is one of the frequent complications in laparoscopic cholecystectomy, which can cause a loss of gallstones in the abdominal cavity. Usually these are removed. But in cases where they are not completely removed it can cause intraabdominal abscess even years after. Here we present a patient who was admitted with a sepsis due to an intraabdominal abscess. *Correspondence to: Nadshathra Varathan, Kleinriehenstrasse 304058 – Basel, Switzerland, E-mail: nadshathra.varathan@clarunis.ch Received: June 12, 2019; Accepted: June 25, 2019; Published: June 28, 2019 Introduction Acute cholecystitis is one of the most frequent encountered acute abdominal diseases worldwide. The prevalence of gallstones is reported in a range between 10% and 15% among adults [1]. Cholesterol gallstones account for 80-90% in western societies. Approximately 80% of gallstones remain asymptomatic [2,3], 1-2% of individuals with gallstones become symptomatic each year [2,4]. Of those with symptomatic gallstones, 10% will develop an acute cholecystitis [5]. In people younger than 50 years, women are three times more likely than men to develop an acute cholecystitis [6]. Laparoscopic cholecystectomy is the standard treatment for acute cholecystitis [7]. The timing of surgical intervention in acute cholecystitis is still a subject of ongoing studies. Initial studies concluded that early laparoscopic cholecystectomy for acute cholecystitis was associated with a higher conversion rate, more complications and longer surgery times [8]. However, with advances in laparoscopic techniques, early laparoscopic cholecystectomy became the standard practice for treatment of acute cholecystitis [7]. One of the common complications of laparoscopic cholecystectomy is a gallbladder perforation [9]. The incidence varies from 1.3 to 40% [10,11]. This can cause gallstone spillage, which in most cases remain clinically asymptomatic, however in 0.04 to 19% of the cases adverse events were reported [11]. The intra-abdominal abscesses formation is the most frequent complication [12]. The presence of pigment stones is correlated to development of complications [12]. We present the case of sepsis due to intraabdominal abscess years after laparoscopic cholecystectomy. Case presentation In July 2018, a 78-year-old male patient presented at the emergency room in an outside hospital with acute right upper quadrant pain and nausea for two days. In the prior weeks he suffered from intermitting fever, loss of appetite and loss of weight. His medical history was remarkable for status post laparoscopic cholecystectomy in 2000 where gallstones were lost and left in the peritoneal cavity. In cause of a sepsis with the need of surveillance in an intensive care unit the patient was moved to our hospital. Infection signs in the blood (white blood cells and CRP) were clearly elevated. The computer tomography (CT) of the abdomen confirmed an abdominal abscess in the right lower quadrant close to the colon ascendens. A CT-guided drainage of the abscess collection was performed, and we began an antibiotic treatment with Piperacillin/Tazobactam 4.5 g three times a day. Due to the cardiac situation and the anticoagulation with Marcoumar (due to an atrial fibrillation) with an INR > 2 an operative treatment could not be performed. The result of the puncture fluid showed enterobacter aerogenes, the antibiotic therapy was adjusted according to the resistance profile to Imipenem 4 × 500 mg. The following CT after two weeks showed a new abscess collection in the iliac and lesser pelvic area, a second drainage was necessary. After another 2 weeks a third drainage had to be placed in another collection in the left paracolic area. Over time the symptoms dissolved, and the infection signs remained normal. The antibiotic treatment was changed to Ciproxin 2 × 500 mg and Co-Amoxicillin 3 × 625 mg p.o. and all three drainages were removed. After 40 days the patient was discharged to a rehabilitation facility.
