Percutaneous removal of "dropped" gallstones after laparoscopic cholecystectomy

Percutaneous Endoscopy and Image-guided Retrieval of Dropped Gallstones - A Case Series

BACKGROUND

Recurrent abscesses can happen due to dropped gallstones (DGs) after laparoscopic cholecystectomy (LC). Recognition and appropriate percutaneous endoscopy and image-guided treatment options can decrease morbidity associated with this condition.

MATERIALS AND METHODS

We report a minimally invasive endoscopy and image-guided technique for retrieval of dropped gallstones in a series of 6 patients (M/F=3/3; median age: 75.5 years [68 to 82]) presenting with recurrent or chronic intra-abdominal abscesses secondary to dropped gallstones. Technical success was defined as the visualization and retrieval of all stones. DGs were identified on pre-procedure imaging. Number of abscesses recurrence was 12 (1/6), 1 (3/6), and 0 (2/6) with a median interval of 2 months (1 to 21) between cholecystectomy and abscess development.

RESULTS

Percutaneous endoscopy and fluoroscopy guidance were utilized in all cases. Technical success was achieved in 4 patients (66%). The median procedure time was 65.8 minutes (39 to 136). The median fluoroscopy time and dose were 12.6 min (3.3 to 67) and 234 mGy (31 to 1457), respectively. There were no intraprocedure and postprocedure complications. No abscess recurrence was reported among successful procedures during a median follow-up of 193 days (51 to 308).

CONCLUSION

Percutaneous image and endoscopy-guided lithotripsy/lithectomy are safe and effective. This technique is a suitable alternative to open surgery for dropped gallstones.

Dropped Gallstone Presenting as Recurrent Abdominal Wall Abscess

Dropped gallstones are a known complication of laparoscopic cholecystectomy. Rarely, dropped stones may be embedded within the potential intraperitoneal spaces or abdominal wall, mimicking metastatic implants, tuberculosis, peritoneal loose body, actinomyces, and primary tumors, which when coupled with the fact that most bile stones are radiolucent, leads to diagnostic challenges. Here, we report a case of abdominal wall abscess due to a dropped stone that presented over 15 years after laparoscopic cholecystectomy. An 86-year-old male with laparoscopic cholecystectomy for management of acute cholecystitis complicated by post-cholecystectomy choledocholithiasis over 15 years back presented to the emergency department with intermittent, asymmetric abdominal “bulging” and a reported 16-pound weight loss of 3 months duration. He remained hemodynamically stable and physical examination demonstrated approximately 9 cm × 7 cm, nontender and slightly fluctuant mass appreciable on the right lateral abdominal wall extending to the right flank. Laboratory revealed leukocytosis and elevated lactic acid. Abdominal ultrasound and abdominal computed tomography demonstrated a 10.6 × 7 × 16 cm cystic mass with echogenic debris adjacent to the anterior segment of the right hepatic lobe. The patient presented multiple times with re-accumulation. A drain was subsequently placed and antibiotic therapy initiated with subsequent resolution. Follow-up magnetic resonance imaging revealed a punctate calcification within the abscess pocket. Retained stones should be considered in the differentials of patients presenting with abdominal discomfort and abdominal “masses.” The clinical suspicion must remain high secondary to the potential temporally prolonged presentation, indolent nature of inflammation, and unusual sites of physical manifestations.

Spilled gallstones simulating peritoneal carcinomatosis: A case report and literature review

INTRODUCTION

Laparoscopic cholecystectomy (LC) has become the "gold standard" for the treatment of symptomatic gallstones. However, this surgical technique increases the risk of bile duct injury and lost gallstones. Since over 90% of split gallstones never become symptomatic, they often present as incidental findings on CT-scans. Careful removal of as many stones as possible, intense irrigation and suction are recommended. It has been reported that 8.5% of lost gallstones will lead to a complication, most common are abscesses.

PRESENTATION CASE

We report a case of spilled gallstones simulating peritoneal metastases on radiological investigations. Diagnosis was very difficult, not even an US-guided biopsy of the lesion was decisive. Only a diagnostic laparoscopy confirms the diagnosis.

DISCUSSION

The reaction associated with lost gallstones can mimic other causes, such as soft tissue sarcoma, malignant lymphoma or, as in our case peritoneal carcinomatosis.

CONCLUSION

Spilled gallstones are associated with uncommon, but significant complications, and even the diagnosis of such a condition can cause serious difficulties. Serious effort must be made to prevent gallbladder perforation, and accidental stone spillage should be promptly recognized and properly managed.

Ultrasound-guided percutaneous retrieval of a dropped gallstone following laparoscopic cholecystectomy

Removal of intraabdominal dropped gallstones remains a challenging problem for both surgeon and radiologist. We describe in this report a novel, minimally invasive technique to successfully remove a dropped gallstone, causing recurrent intra-abdominal infection, from a patient who had undergone laparoscopic cholecystectomy.

Gastric outlet obstruction by a lost gallstone: Case report and literature review

INTRODUCTION

Spilled gallstones from a laparoscopic cholecystectomy can be a source of significant morbidity, most commonly causing abscesses and fistulae. Preventative measures for loss, careful removal during the initial surgery, and good documentation of any concern for remaining intraperitoneal stones needs to be performed with the initial surgery.

CASE REPORT

An 80-year-old male with a history of complicated biliary disease resulting in a cholecystectomy presented to general surgery clinic with increasing symptoms of gastric outlet obstruction. CT imaging was concerning for a malignant process despite negative biopsies. A distal gastrectomy and Billroth II reconstruction was performed and final pathology showed dense inflammation with a single calcified stone incarcerated within the gastric wall of the inflamed pylorus and no malignancy.

DISCUSSION

Stones lost during laparoscopic cholecystectomy are not innocuous and preventative measures for loss, careful removal during the initial surgery, and good documentation of any concern for remaining intraperitoneal stones.

CONCLUSION

This is the first case of gastric outlet obstruction caused by an intramural obstruction of the pylorus from a spilled gallstone during a laparoscopic cholecystectomy and subsequent inflammation. This is an etiology that must be considered in new cases of gastric outlet obstruction and can mimic malignancy.

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.

Laparoscopic management of chronic abscess due to spilled gallstones

INTRODUCTION

Bile and gallstones are spilled during 13% to 40% of all laparoscopic cholecystectomies. They can act as a septic focus and cause complications. We present 2 cases of perihepatic abscess formation due to dropped gallstones presenting some years later. Delayed diagnosis resulted in unnecessary investigations and had negative economic consequences.

CASE DESCRIPTION

In 1 patient a posterolateral cutaneous fistula had developed that was initially biopsied by cardiothoracic surgeons before computed tomography showed the cause. The other patient presented with recurrent Pyrexia of unknown origin (PUO) causing repeated absence from work and was diagnosed only after 18 months of medical investigation. Both patients were treated with laparoscopic drainage of the abscess and successful retrieval of all stones.

DISCUSSION

Radiologic and open drainage and retrieval of stones have been well described in these cases. We suggest that a laparoscopic approach is superior because the cavity can be clearly identified and stones visualized and removed under direct vision. The need for a formal laparotomy is avoided. We also highlight the economic burden to both patient and health care professional of delayed diagnosis, as shown in these 2 cases. Spilled gallstones are a recognized complication of laparoscopic cholecystectomy. All stones should be actively sought and removed to avoid complications. Laparoscopic drainage is preferable to open or radiologic drainage. Dropped gallstones should be considered a possible diagnosis in patients who have had a previous cholecystectomy and present with unusual symptoms.

Asymptomatic omental granuloma following spillage of gallstones during laparoscopic cholecystectomy protects patients and influences surgeons' decisions: a review

Spillage of gallstones in the peritoneal cavity during laparoscopic cholecystectomy (LC) occurs at rates varying from 5.7% to 16%. These gallstones often cannot be retrieved and can cause early and late abscesses at rates ranging from 0.08% to 1.4%. The case of an 86-year-old woman with colon cancer is described because during an elective right hemicolectomy a granuloma of the omentum with retained gallstones from LC performed 8 years earlier was unexpectedly found. Importantly, the gallstones were found high up in the abdominal cavity. Moreover, this report reaffirms the excellent response of the peritoneal cavity defence mechanisms for protecting patients against gallstones through asymptomatic omental granuloma. Current data indicate that every effort should be made to retrieve spilled gallstones, but routine conversion to an open cholecystectomy is not recommended. Identifying factors that impair host defence mechanisms should help surgeons' decision-making.

Combined percutaneous and endoscopic approach in management of dropped gallstones following laparoscopic cholecystectomy

Dropped gallstones due to accidental perforation of gallbladder wall during laparoscopic cholecystectomy are often encountered. However, dropped gallstones as nidus of infection with subsequent abscess formation is a rare complication of laparoscopic cholecystectomy (0.3%). Most of the reported cases of complicated dropped stones required open surgical drainage. Minimally invasive measures were less frequently employed. We report a case of dropped gallstones that were removed endoscopically through a percutaneous drainage tract.

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.

Retroperitoneoscopy to Extract Dropped Gallstones After Laparoscopic Cholecystectomy

Complications resulting from gallstones left in the peritoneal cavity are most often reported after laparoscopic treatment of cholelitiasis. Gallstones are frequently dropped in the posterior subhepatic space, which can lead to the development of abscesses that usually require laparotomy for extraction of the stones. We present a novel technique for treating collections associated with dropped gallstones, using retroperitoneoscopy with two 10-mm ports after ultrasound localization of the abscess. We carried out this procedure in two patients and successfully extracted the gallstones without postoperative complications or recurrences. We consider this approach to be technically feasible, safe, and effective. It avoids the usual inefficacy of simple percutaneous drainage of these collections and the complications associated with the drainage of intra-abdominal abscesses by laparotomy.

Spilled gallstones after laparoscopic cholecystectomy

Spilled gallstones have emerged as a new issue in the era of laparoscopic cholecystectomy. We treated a 77-year-old woman who underwent laparoscopic cholecystectomy. Subsequently, a right flank abscess developed. During the cholecystectomy, the gallbladder was perforated and stones were spilled. After a failed attempt to drain the abscess percutaneously, the patient required open drainage, which revealed retained gallstones in the right flank. The abscess resolved, although the patient continued to have intermittent drainage without evidence of sepsis. Review of the literature revealed 127 cases of spilled gallstones, of which 44.1% presented with intraperitoneal abscess, 18.1% with abdominal wall abscess, 11.8% with thoracic abscess, 10.2% with retroperitoneal abscess, and the rest with various clinical pictures. In case of gallstone spillage during laparoscopic cholecystectomy, every effort should be made to locate and retrieve the stones.

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.

EFEITO DE CÁLCULOS BILIARES HUMANOS NA CAVIDADE PERITONEAL DE RATOS

Este estudo tem por objetivo analisar experimentalmente as características macroscópicas e microscópicas de cálculos biliares humanos na cavidade peritoneal de ratos. Foram utilizados 32 ratos Wistar, machos, pesando entre 205 e 268 g. Estes animais foram distribuídos em dois grupos e o procedimento cirúrgico foi realizado em cada grupo: no grupo A (n =16), os animais foram submetidos a manipulação intestinal; no grupo B (n=16), cálculos biliares humanos foram colocados na cavidade peritoneal. Os ratos foram avaliados no 21º e 42º dias do período pós-operatório. Os resultados mostraram que a simples manipulação causou aderências nos animais (n=10). As aderências foram notadas em 11 cálculos no grupo B. Histologicamente não houve fibrose intensa em torno do cálculo, principalmente no 42º dia do período pós-operatório. Não foram observados macro ou micro abscessos e não houve evidências de fluído livre intra-peritoneal. Este estudo demonstra que apesar da baixa incidência de complicações, todas as tentativas devem ser feitas para recuperar cálculos perdidos durante colecistectomia.

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.

Retroperitoneal abscess as a complication of retained gallstones following laparoscopic cholecystectomy

Retroperitoneal abscess formation secondary to retained spilled gallstones after laparoscopic cholecystectomy is a rare complication. We describe the case of a patient with this complication as well as a novel method utilizing interventional radiologic localization with subsequent operative drainage and removal of the stones. A review of the literature is provided.

Abscess formation due to dropped gallstone after laparoscopic cholecystectomy

Laparoscopic cholecystectomy is a popular treatment modality of symptomatic gallstones with decreased major complications and shortened hospital stay. Complications following laparoscopic cholecystectomy, most of them involving strictures of biliary tract have been well described in recent reports. However, there are only a few reported cases about dropped gallstones after the procedure, all of which were opaque and easily demonstrated with multiple imaging modalities. An unusual complication of laparoscopic cholecystectomy; abscess formation due to a dropped non-opaque gallstone is described in which diagnosis was suggested with the combination of ultrasound and computed tomography findings and confirmed by surgery.

Abscesses caused by "dropped" stones after laparoscopic cholecystectomy for cholelithiasis: a report of three cases

While laparoscopic cholecystectomy is a standard therapeutic option for gallbladder stones, it is associated with a significant risk of injury to the gallbladder wall, which may result in the dispersion of free stones within the peritoneal cavity. However, the incidence and consequences of these dropped stones remains unclear. We report herein the cases of three patients in whom abdominal abscesses developed as a result of dropped stones during this procedure. Of particular interest was the relatively long interval from the procedure to the onset of symptoms and the unusual progression of the inflammation. These case reports strongly reinforce the risk of dropped stones during laparoscopic cholecystectomy.

Complex pleural effusion associated with a subphrenic gallstone phlegmon following laparoscopic cholecystectomy

A 90-year-old man presented with a large right-sided complex pleural effusion 4 months after a laparoscopic cholecystectomy. An initial thoracic CT scan confirmed the presence of the effusion, and the results of thoracentesis on three separate occasions were consistent with an exudative process. Another CT scan of the chest with thin-section cuts through the diaphragm along with an abdominal ultrasound revealed a retrohepatic subdiaphragmatic gallstone collection that eroded into the right hemidiaphragm. Thoracoscopic evacuation of the phlegmon, removal of the spilled gallstones, and repair of the diaphragm resulted in resolution of the effusion.

Lost gallstones found in a hernial sac

Spillage of bile and gallstones is not a rare event during laparoscopic cholecystectomy. The natural history of spilled and retained stones is not well defined. We report of such lost stones that were found several months later in a hernia sac.

The treatment of gall stones

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.

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.

Cholelithoptysis: an unusual complication of laparoscopic cholecystectomy

Laparoscopic cholecystectomy is emerging as a preferred surgical method in the treatment of cholecystitis. Decreased morbidity and mortality rates make this an attractive alternative to conventional cholecystectomy. Recently, specific complications including bile duct transection, biloma formation, and liver lacerations have been reported. We report here, however, an unusual case of intraoperative spillage of stones into the intraperitoneal cavity. Subsequent erosion through the diaphragm resulted in expectoration of stones, or cholelithoptysis.
