Laparoscopic cholecystectomy. Leave no (spilled) stone unturned

Consequences of Lost Gallstones During Laparoscopic Cholecystectomy: A Review Article

BACKGROUND

Laparoscopic cholecystectomy (LC) has become a popular and widespread procedure for the treatment of gallstone disease. There is still an increasing concern about specific complications of LC due to gallbladder perforation and spillage of bile and stones. Although unretrieved intraperitoneal gallstones rarely become symptomatic, their infective complications may cause serious morbidities even after a long interval from LC.

METHODS

We performed a review of the literature on the diagnosis, prevention, consequences, and management of lost gallstones. All studies with a focus on lost gallstones or perforated gallbladder were analyzed to evaluate the postoperative complications.

RESULTS

Between 1991 and 2015, >250 cases of postoperative complications of spilled gallstones were reviewed in the surgical literature. The most common complications are intraperitoneal abscesses and fistulas. Confusing clinical pictures due to gallstones spreading in different locations makes diagnosis challenging. Even asymptomatic dropped gallstones may masquerade intraperitoneal neoplastic lesions.

CONCLUSIONS

Every effort should be made to prevent gallbladder perforation; otherwise, they should be retrieved immediately during laparoscopy. In cases with multiple large spilled stones or infected bile, conversion to open surgery can be considered. Documentation in operative notes and awareness of patients about lost gallstones are mandatory to early recognition and treatment of any complications.

Gallstone-related abdominal abscess 8 years after laparoscopic cholecystectomy

An unusual collection of fluid in the perihepatic space needs to be investigated for abscess in patients with a remote history of cholecystectomy.

Background:

A common intraoperative complication during laparoscopic cholecystectomy is gallbladder perforation with spillage of gallstones. The undesirable consequence of spilled gallstones is the formation of abscesses months or years after an operation.

Case Description:

Our clinical report describes an intraabdominal abscess formation in an 82-year-old man that developed 8 years after a laparoscopic cholecystectomy. A computed tomography scan of the abdomen showed an elongated fluid collection in the right abdominal compartment musculature at the level of the internal oblique muscle. Abdominal ultrasonography confirmed a large fluid collection, with 2 echogenic masses in the dependent portion. Incision and drainage of the abscess were performed, and 2 gallstones were found.

Conclusion:

Any unusual collection of fluid in the perihepatic space and abdominal wall in the area of the surgical incision in a patient with a remote history of cholecystectomy should be evaluated for abscess related to retained gallstone. Early abscess formation is usually diagnosed and treated by the surgeon. However, the late manifestation might be a clinical problem seen in the primary care physician's office. Therefore, the primary care physician should incorporate diagnosis of gallstone-related abscess in patients with abdominal abscess formation of unknown etiology.

Consequences of spilt gallstones during laparoscopic cholecystectomy

To document the incidence of spilt gallstones during laparoscopic cholecystectomy, the cause and consequences of such spillage. The study included 150 consecutive laparoscopic cholecystectomies performed between October 2007 and November 2008. Data was collected in a prospective manner in accordance to proforma. Follow up were performed at the end of 1 week, 1 month, 6 months and 1 year. The spillage of gall stones during surgery occurred in 19.04 % of the cases. Majority of the spillage occurred due to perforation of the gall bladder during dissection, followed by application of toothed grasper. Although all visible spilt stones were retrieved during surgery, complication rate of 0.66 % was observed. The incidence and complications secondary to the spillage of gall stones during standard laparoscopic cholecystectomy is low but avoidable. Various complications can occur, over a large period of time. Thus it is advisable to retrieve as many gallstones as possible short of converting to a laparotomy Dasari and Loan (JSLS 13(1):73-76, 2009), Daradkeh and Suwan (World J Surg 22:75-77, 1998).

Complications of laparoscopic cholecystectomy: our experience in a district general hospital

BACKGROUND

Laparoscopic cholecystectomy is the procedure of choice for the treatment of symptomatic gallstone disease. Some of the associated complications are rare, but often serious. The purpose of this study is to present our data about the type and the incidence of these complications and our experience in their management, in a district hospital, during the last 8 years.

PATIENTS AND METHODS

A retrospective study was performed on 1009 patients, 229 males and 780 females, with age ranging from 19 to 84 years, who underwent laparoscopic cholecystectomy for symptomatic gallstone disease, during the period from January 2000 to January 2008. The procedure was performed urgently due to acute cholecystitis in 78 patients (7.73%).

RESULTS

Complications occurred in 96 (9.51%) patients. Bile leakage occurred in 15 patients (1.49%). One patient (0.10%) had a major bile duct injury (common bile duct transection). Bleeding occurred in 9 patients (0.89%), wound infection in 14 patients (1.39%), abdominal wall hematomas in 3 patients (0.30%), omental hematoma in 3 patients (0.30%), port site hernias in 3 patients (0.30%), subphrenic abscess in 1 patient (0.10%), subcapsular liver hematoma in 1 patient (0.10%), bowel injury in 5 patients (0.51%), postoperative acute pancreatitis in 4 patients (0.40%), respiratory and cardiovascular complications in 11 patients 1.09%). Finally in 14 patients (1.39%), the gallbladder was unintentionally opened during laparoscopic procedure and spillage of gallstones occurred into the peritoneal cavity. All patients had satisfactory results and no death occurred.

CONCLUSIONS

We conclude that laparoscopic cholecystectomy is a safe procedure, although it is associated with some serious complications. The most usual complication during laparoscopic cholecystectomy is bile leakage, which remains a significant cause of morbidity. Early identification and management of these complications will minimize a potentially devastating outcome.

Lost gallstones in laparoscopic cholecystectomy: all possible complications

BACKGROUND

Laparoscopic cholecystectomy (LC) has been the gold standard for symptomatic gallstones for 15 years. During that time, several studies and case reports have been published which outline the possible complications of lost gallstones. The aim of this review is to categorize these complications and to evaluate the frequency and management of lost gallstones.

DATA SOURCES

A Medline search from 1987 to 2005 was performed. A total of 111 case reports and studies were found, and all reported complications were listed alphabetically. Eight studies with more than 500 LCs that reported lost gallstones and perforated gallbladder were analyzed for frequency and management of lost gallstones.

CONCLUSION

Lost gallstones have a low incidence of causing complications but have a large variety of possible postoperative problems. Every effort should be made to remove spilled gallstones to prevent further complications, but conversion is not mandatory.

Peritoneal gallstones following laparoscopic cholecystectomy

BACKGROUND

Gallstone spillage during laparoscopic cholecystectomy (LC) is a common intraoperative event. Although gallstones left in the peritoneal cavity were initially considered harmless, a significant number of complications have been reported. Our aim was to quantify the likelihood, and to document the range, of subsequent complications.

METHODS

A Medline search from 1987 to January 2003 was performed. Articles with more than 500 LCs that quantified the frequency of complications due to peritoneal gallstones were reviewed, as were representative case studies of different stated complications.

RESULTS

Six studies, covering 18,280 LCs, were found. The incidence of gallbladder perforation was 18.3%, that of gallstone spillage was 7.3%, and that of unretrieved peritoneal gallstones was estimated to be 2.4%. There were 27 patients with complications. The likelihood of a complication when gallstone spillage occurred was 2.3%, which increased to 7.0% when unretrieved peritoneal gallstones were documented.

CONCLUSION

Spilt gallstones have a small but quantifiably real risk of causing a wide range of significant postoperative problems.

Transdiaphragmatic abscess: late thoracic complication of laparoscopic cholecystectomy

Spillage of gallstones into the peritoneal cavity is a frequent problem during laparoscopic cholecystectomy (as much as 30%) and is frequently dismissed as a benign occurrence. However, several complications associated with spillage of gallstones have been reported recently. Most of these complications presented late after the original procedure, many with clinical pictures not related to biliary etiology, confounding and delaying adequate management. For patients presenting with intraabdominal or thoracic abscesses of unknown etiology, if there is a history of laparoscopic cholecystectomy, regardless of the time interval, certain evaluations should be considered. A sonogram and a CT scan are advisable to detect retained extraluminal gallstones, as most patients will require, not only drainage of fluid collections, but also removal of the stones. A case is described of a patient who presented with a right empyema and transdiaphragmatic abscess 18 months after a laparoscopic cholecystectomy. Treatment included decortication, enbloc resection of the abscess, repair of the diaphragm, and drainage.

Iatrogenic Gallbladder Perforation during Laparoscopic Cholecystectomy: Etiology and Sequelae

Iatrogenic perforation of the gallbladder (PGB) during laparoscopic cholecystectomy (LC) leads to spillage of bile and gallstones into the peritoneal cavity, which can result in serious postoperative infection. The objective of this study is to prospectively evaluate with long-term follow-up the risk factors, mechanisms, and complications associated with PGB in patients undergoing LC. Data from 1412 patients undergoing LC were collected prospectively between 1989 and 1995. Patients with and without iatrogenic gallbladder perforation were compared. Long-term follow-up was obtained using mailed questionnaires and telephone interviews, when needed. Of the 1412 patients, 512 (36%) sustained a PGB. Male sex, weight, gallbladder inflammation, thickening of the gallbladder, presence of adhesions, and a difficult hilar dissection were all associated with an increased incidence of PGB. The most common mechanisms of PGB were laceration due to grasper traction (55%) and electrocautery dissection (40%). Both the operating time and length of hospital stay were significantly longer in the PGB group. No difference was observed in the rate of wound infections between PGB and non-PGB patients (1.6% versus 1.8%). Only one patient (with an inflamed and perforated gallbladder) developed an early postoperative intra-abdominal abscess. Long-term follow-up averaging 48 months was achieved with a response rate of 44 per cent. No late intra-abdominal abscesses or complications attributable to retained gallstones were discovered.

Unusual abscess patterns following dropped gallstones during laparoscopic cholecystectomy

BACKGROUND

Laparoscopic cholecystectomy has become the standard treatment for symptomatic cholelithiasis. Numerous clinical trials have deemed it a safe procedure, regardless of the known increased risk of bile duct injury. However, the consequences and incidence of less well-known complications are still being addressed.

METHODS

Between 1993 and 1995, 1,130 laparoscopic cholecystectomies were performed at two major metropolitan medical centers. Of these patients, we know of 3 (0.3%) who subsequently developed abscesses as a consequence of dropped stones during the laparoscopic cholecystectomy. One additional patient who underwent prior laparoscopic cholecystectomy at another institution developed late infection as well.

RESULTS

All 4 patients developed late purulent abscesses that ultimately required open surgical drainage, and 1 patient developed trocar site "tumor" masses that were secondary to inflammatory tissue around gallstone fragments. All patients were successfully treated by surgical drainage, stone removal, and antibiotics. Trocar site inflammatory masses required excision only. Significant costs were involved in the diagnosis, management, and duration of therapy for these problems.

CONCLUSIONS

This experience closely resembles that of other centers and points out the existence of a late postoperative complication following laparoscopic cholecystectomy that was rarely encountered with open cholecystectomy. Strategies for avoiding this problem are discussed. Whether dropped stones are an indication for conversion to open cholecystectomy remains unclear. Thorough irrigation at time of laparoscopic cholecystectomy with or without placement of a drain in the subhepatic space does not prevent this complication.

The fate of intraperitoneally retained gallstones with different morphologic and microbiologic characteristics: an experimental study

Management of intraperitoneally retained gallstones after laparoscopic cholecystectomy (LC) is controversial, as their natural course is not known. This study was undertaken to assess the probable effects of stone morphology and clinically obvious infection on the outcome of retained gallstones in a mouse model. Forty albino mice were divided into four groups. Group I served as the control group (simple laparotomy, n = 10). Groups II, III, and IV (n = 10 in each group) were study groups. "Intact-sterile-cholesterol" (group II), "crushed-sterile-cholesterol" (group III), and "intact" (n = 5) [group IVa] and "crushed" (n = 5) [group IVb] "infected-cholesterol" gallstones aseptically retrieved from three different human patients were implanted to the peritoneal cavity of the animals. Group IV animals were implanted with stones retrieved from an acutely inflamed gallbladder with proven infection. Animals were sacrificed 6 and 12 weeks after the operations. Cultures and tissue samples were obtained. No animal was lost, no microscopic or macroscopic abnormality was observed in groups I and II, and cultures remained negative. In group III, adhesions surrounding the fragmented stones were evident at the 12th week, and no mortality was encountered. The histopathology revealed a fibroblastic reaction, and cultures remained negative in group III. In group IV, three animals from group IVb and one animal from group IVa died because of intra-abdominal sepsis before their sacrifice. All remaining mice showed severe adhesions with localized abscesses at the 12th week. In conclusion, intraperitoneally retained cholesterol gallstones remain inert and do not cause serious peritoneal reaction unless they are crushed into fragments or are from an acutely inflamed gallbladder. It is for this group of patients that laparotomy for total stone clearance is probably not justifiable. Better stone retrieval techniques or even laparotomy may be worthwhile considering in patients with crushed and particularly infected retained stones.

Spilled gallstones causing pelvic pain

Spillage of gallstones in laparoscopic cholecystectomy has resulted in an increase in reported complications. Surgeons must be aware of the long-term morbidity associated with this adverse event.

The spilled stone. A potential danger after laparoscopic cholecystectomy

The application of laparoscopic techniques in digestive surgery to areas in which there was no previous experience has favored the appearance of new complications and clinical situations that were not observed during the open era. Initial opinion considered that stones left in the abdominal cavity were harmless, and a few clinical and experimental studies supported this opinion. But cumulative reports of cases suggest a potential danger. From 1991 to date, 49 cases of complications related to stones left in the abdominal cavity have been reported with severe complications that required an open surgical procedure. Stone spillage has not always been considered an indication of conversion of laparoscopic cholecystectomy but is now accepted as a source of infrequent but severe complications that may require a reintervention for treatment. Therefore it is recommended that efforts should be made to retrieve all spilled stones; the surgical procedure should be prolonged until this is achieved, in order to reduce one source of unpredictable morbidity. Open retrieval should be considered in selected cases if a large number or large stones are lost.

Incarcerated paraumbilical incisional hernia and abscess--complications of a spilled gallstone

Gallstones may fall into the peritoneal cavity during performance of cholecystectomy. They are more easily retrieved in an open operation. Some controversy exists as to what should be done with gallstones lost during laparoscopic cholecystectomy (LC) because complications of abandoned stones have been reported. This case report describes a patient who presented with an incarcerated hernia and an associated abscess cavity containing a large spilled gallstone, which on computed tomography scan suggested a possible abdominal wall tumor. Spilled stones may cause subsequent problems and should be removed whenever possible, but should not be an indication for conversion to open operation.

Abscess formation as a late complication of dropped gallstones

We describe a case of abscess formation 1.5 years postoperatively in a patient with dropped gallstones from laparoscopic cholecystectomy. The entity was initially recognized on computed tomography (CT) and the diagnosis was confirmed with ultrasound. Although this is a rare complication of laparoscopic cholecystectomy, it should be recognized as a potential source of abscess formation even in a patient presenting months after the procedure.
