Spilled gallstones found incidentally in a direct inguinal hernia sac: Report of a case

Lost gallstones during laparoscopic cholecystectomy as a common but underestimated complication-case report and review of the literature

Introduction

Laparoscopic cholecystectomy (LC) represents one of the most commonly performed routine abdominal surgeries. Nevertheless, besides bile duct injury, problems caused by lost gallstones represent a heavily underestimated and underreported possible late complication after LC.

Methods

Case report of a Clavien-Dindo IVb complication after supposedly straightforward LC and review of all published case reports on complications from lost gallstones from 2000-2022.

Case Report

An 86-year-old patient developed a perihepatic abscess due to lost gallstones 6 months after LC. The patient had to undergo open surgery to successfully drain the abscess. Reactive pleural effusion needed additional drainage. Postoperative ICU stay was 13 days. The patient was finally discharged after 33 days on a geriatric remobilization ward and died 12 months later due to acute cardiac decompensation.

Conclusion

Intraabdominal abscess formation due to spilled gallstones may present years after LC as a late complication. Surgical management in order to completely evacuate the abscess and remove all spilled gallstones may be required, which could be associated with high morbidity and mortality, especially in elderly patients. Regarding the overt underreporting of gallstone spillage in case of postoperative gallstone-related complications, focus need be put on precise reporting of even apparently innocuous complications during LC.

Incarcerated Inguinal Hernia Containing a Gallstone Found Decades After a Laparoscopic Cholecystectomy

Iatrogenic gallbladder perforation and subsequent gallstone spillage is a common problem in laparoscopic cholecystectomy. While most commonly asymptomatic, complications due to spilled gallstones have been reported. In this case study, we report the case of a 96-year-old female with a history of laparoscopic cholecystectomy at an unknown time who presented with an incarcerated inguinal hernia and small bowel obstruction. Imaging revealed an extraluminal radiopaque foreign body located near the hernia sac. At the time of the repair, she was found to have a single gallstone located within the hernia sac, confirmed by pathology. The hernia was repaired using Lichtenstein, and her bowel obstruction was resolved postoperatively. Although gallstone spillage from iatrogenic gallbladder perforation during laparoscopic cholecystectomy is a relatively common problem, it is rarely symptomatic and may be associated with infection, abscess, and fistula formation. A rarer complication includes the formation of hernias containing gallstones, documented in fewer than 10 cases in the literature. This case demonstrates a rare consequence of leaving behind spilled gallstones following gallbladder perforation during laparoscopic cholecystectomy. It emphasizes the importance of preventing iatrogenic gallbladder perforation and retrieving any spilled gallstones during the procedure to minimize associated complications.

Consequences of the spilled gallstones during laparoscopic cholecystectomy: a systematic review

INTRODUCTION

Complications secondary to spilled gallstones can be classified in the category of disease of medical progress because prior to advent of laparoscopic cholecystectomy very few reports published on the topic. The aim of the present study was to investigate the predisposing factors and the complication rate of spilled gallstones during laparoscopic cholecystectomy over the past 21 years.

METHODS

Embase, Pubmed, Medline, Google scholar and Cochrane library were systematically searched for pertinent literature.

RESULTS

Seventy five out of 181 articles were selected including 85 patients; of those 38% were men and 62% women. The median age of the cohort was 64 years old and ranged between 33 and 87 years. Only 23(27%) of the authors reported the incident of spillage of the gallstones during the operation. Time of onset of symptoms varied widely from the second postoperative day to 15 years later. Ten of 85 patients were asymptomatic and diagnosed with spilled gallstones incidentally. The rest of the patients presented with complications of severe morbidity and almost, 87% of the patients needed to be treated with surgical intervention and 12% with US ± CT scan guidance drainage. Only one perioperative death reported.

CONCLUSIONS

Symptomatic patients with lost gallstones present with severe morbidity complications and required mostly major surgical procedures. Therefore, standardisation of the management of spilled gallstones is needed urgently. Hospitals need to review their policy with audits and recommendations and clinical guidelines are needed urgently.

Spilled gallstones after laparoscopic cholecystectomy: a systematic review

<b> Aim: </b> The study was conducted to analyse the recent peer-reviewed literature related to symptomatic spilled gallstones after Laparoscopic Cholecystectomy (LC). </br></br> <b>Materials and methods:</b> Articles published in the peer-reviewed journals of repute from 20122022 were evaluated for nine variables including: [I] age of the patient, [II] gender, [III] interval since index LC, [IV] index LC if emergent/difficult or elective/straightforward, [V] clinical presentation, [VI] spilled gallstones if detected by imaging, [VII] management, [VIII] approach to management, [IX] number of spilled gallstones. </br></br> <b>Results:</b> There were a total of 71 cases (37 males and 34 females) with a mean age of 63.7 years. The time of onset of symptoms from spilled gallstones, after index LC, ranged from 2 days to 15 years and 57 patients (80.3%) presented within 6 years. Forty (56.3%) patients were unaware of the fact that gallstone spillage had occurred during index LC. The retained gallstones were detected by imaging in 47 (66.1%) cases and they were multiple in 51 (71.8%). In 52 patients (73.2%), the stones manifested as abdominal abscess/foreign body granuloma; the other presentations being pelvic pain/fistula, intestinal obstruction, abdominal lump simulating malignancy, incidental finding of metastatic lesions and generalized peritonitis. The major approaches adopted to retrieve the retained stones included open surgery, laparoscopy and percutaneous drainage. There were two deaths (2.9%) due to spilled gallstones. </br></br> <b>Conclusion:</b> Retained gallstones represent a complication of laparoscopic cholecystectomy (LC) that has a potential to create morbidity and diagnostic difficulties, even after a substantial delay. There is a need to spread awareness about the adverse effects of spilled stones so that they are actively looked for and retrieved if gallbladder perforates during cholecystectomy. Whenever such a complication occurs, the patient should be properly informed and the details should be very clearly mentioned in the operation notes.

Management of Postcholecystectomy Complications

Cholecystectomy is one of the most common general surgery procedures performed worldwide. Complications include bile duct injury, strictures, bleeding, infection/abscess, retained gallstones, hernias, and postcholecystectomy syndrome. Obtaining a critical view of safety and following the other tenets of the Safe Cholecystectomy Task Force will aid in the prevention of bile duct injury and other morbidity associated with cholecystectomy.
