Gallstone Disease

Positive association between advanced lung cancer inflammation index and gallstones, with greater impact on women: a cross-sectional study of the NHANES database

Background

Previous studies have shown that inflammation is crucial in gallstone formation. The Advanced Lung Cancer Inflammation Index (ALI) is a comprehensive measure that reflects inflammation and nutritional condition. However, there are no studies examining the relationship between ALI and gallstones. This study aimed to analyze this association in US adults.

Methods

This study used a cross-sectional research design with in-depth analyses using data from the National Health and Nutrition Examination Survey (NHANES). The association between gallstones and ALI was systematically assessed by logistic regression analysis, subgroup analysis, basic participant characteristics, and smooth curve fits.

Results

5,646 people participated in the study. ALI was converted into Quartile 1 (-1.47-1.00), Quartile 2 (1.00-1.34), Quartile 3 (1.34-1.69), and Quartile 4 (1.69-4.38). In the fully adjusted model, gallstone prevalence increased by 45% in participants in the highest quartile compared to those in the lowest quartile (OR = 1.45; 95% CI: 1.12-1.87; p = 0.005), and ALI was positively correlated with gallstones (OR = 1.22; 95% CI: 1.03-1.45; p = 0.0232). Smooth curve fits provided evidence in favor of this finding. Significant gender differences were found in the relationship between gallstones and ALI by subgroup analysis (OR = 1.43; 95% CI: 1.16-1.76; p for interaction = 0.0204).

Conclusion

The study concluded that ALI and gallstones had a positive correlation, with ALI having a higher effect on women's gallstone prevalence.

What are the clues to gallstone ileus when stones don't show up on scans? A case presentation and literature review

Gallstone ileus is a rare yet significant cause of mechanical bowel obstruction, particularly in elderly patients. This condition arises when gallstones migrate into the gastrointestinal tract through a cholecystoenteric fistula, often due to chronic inflammation. Despite medical advancements, gallstone ileus remains associated with high morbidity and mortality rates due to delayed diagnosis and nonspecific symptoms. The clinical presentation typically includes intermittent nausea, vomiting, abdominal pain, and constipation, which can obscure the diagnosis. Advanced imaging techniques, especially computed tomography (CT), are crucial for identifying key diagnostic features such as pneumobilia, ectopic gallstones, and signs of bowel obstruction. Gallstone ileus should be considered in any case of small bowel obstruction, even if CT imaging is inconclusive, as gallstones can be radiolucent. Indirect clues like pneumobilia and dilated small bowel loops can lead to the diagnosis. Effective management of gallstone ileus requires prompt surgical intervention to remove the obstructing gallstone and restore bowel patency. The primary surgical procedure is enterolithotomy, although additional procedures such as cholecystectomy and fistula repair may be necessary depending on the patient's condition and intraoperative findings. The choice of surgical approach should be individualized, considering the patient's overall health and the specific characteristics of the obstruction. Early recognition and timely surgical management are essential to prevent complications and improve patient outcomes.

Small bowel obstruction secondary to gallstone ileus: An unusual presentation of cholelithiasis

INTRODUCTION AND IMPORTANCE

Gallstone ileus remain a rare but significant cause of small bowel obstruction, especially in the elderly population. It is associated with high mortality due to nonspecific symptoms and delayed diagnosis.

CASE PRESENTATION

A 69-year-old male with a history of cholelithiasis presented with symptoms and signs suggestive of small bowel obstruction. Computed tomography (CT) scan showed pneumobilia, and small bowel obstruction, suggestive of gallstone ileus. Initial management involved exploratory laparotomy with enterotomy and gallstone removal followed by cholecystectomy and fistula closure three months later.

CLINICAL DISCUSSION

Gallstone ileus results from large gallstones causing mechanical intestinal obstruction, often via a cholecysto-intestinal fistula. CT scans are crucial for diagnosis, with surgical options for better patients' outcomes. Management of gallstone ileus involves removing the obstruction and repairing the cholecysto-intestinal fistula, but surgical approaches vary based on patient factors.

CONCLUSION

Surgeons should be aware of the variable clinical presentations and the rationale behind choosing either a one-stage or staged surgical approach, particularly in managing patients with fistulas or severe adhesions.

Imaging of Biliary Tree Abnormalities

Pathologic conditions of the biliary system, although common, can be difficult to diagnose clinically. Challenges in biliary imaging include anatomic variants and the dynamic nature of the biliary tract, which can change with age and intervention, blurring the boundaries of normal and abnormal. Choledochal cysts can have numerous appearances and are important to diagnose given the risk of cholangiocarcinoma potentially requiring surgical resection. Choledocholithiasis, the most common cause of biliary dilatation, can be difficult to detect at US and CT, with MRI having the highest sensitivity. However, knowledge of the imaging pitfalls of MRI and MR cholangiopancreatography is crucial to avoid misinterpretation. Newer concepts in biliary tract malignancy include intraductal papillary biliary neoplasms that may develop into cholangiocarcinoma. New paradigms in the classification of cholangiocarcinoma correspond to the wide range of imaging appearances of the disease and have implications for prognosis. Accurately staging cholangiocarcinoma is imperative, given expanding curative options including transplant and more aggressive surgical options. Infections of the biliary tree include acute cholangitis or recurrent pyogenic cholangitis, characterized by obstruction, strictures, and central biliary dilatation. Inflammatory conditions include primary sclerosing cholangitis, which features strictures and fibrosis but can be difficult to differentiate from secondary causes of sclerosing cholangitis, including more recently described entities such as immunoglobulin G4-related sclerosing cholangitis and COVID-19 secondary sclerosing cholangitis. The authors describe a wide variety of benign and malignant biliary tract abnormalities, highlight differentiating features of the cholangitides, provide an approach to interpretation based on the pattern of imaging findings, and discuss pearls and pitfalls of imaging to facilitate accurate diagnosis. ©RSNA, 2024 Supplemental material is available for this article.

Association between monocyte-to-high-density lipoprotein-cholesterol ratio and gallstones in U.S. adults: findings from the National Health and Nutrition Examination Survey 2017-2020

BACKGROUND

Studies have indicated that monocyte-to-high-density lipoprotein cholesterol ratio (MHR) can be a reliable indicator of various diseases. However, the association between MHR and gallstone prevalence remains unclear. Therefore, this study aimed to explore any potential association between MHR and gallstone prevalence.

METHODS

This study used data from the National Health and Nutrition Examination Survey (NHANES) 2017-March 2020. MHR was calculated as the monocyte count ratio to high-density lipoprotein cholesterol levels. Multiple logistic regression models, Cochran-Armitage trend test, and subgroup analyses were used to examine the association between MHR and gallstones.

RESULTS

This study included 5907 participants, of whom 636 (10.77%) were gallstone formers. The study participants had a mean age of 50.78 ± 17.33 years. After accounting for multiple covariables, the multiple logistic regression model showed a positive linear association between MHR and gallstone odds. The subgroup analyses and interaction testing results revealed that the association between MHR and gallstones was statistically different across strata, including sex, smoking, asthma, and hypertension.

CONCLUSIONS

Gallstone prevalence positively associated with elevated MHR, indicating that MHR can be employed as a clinical indicator to assess gallstone prevalence.

Mirizzi syndrome: Problems and strategies

Mirizzi syndrome is a serious complication of gallstone disease. It is caused by the impacted stones in the gallbladder neck or cystic duct. One of the features of Mirizzi syndrome is severe inflammation or dense fibrosis at the Calot's triangle. In our clinical practice, bile duct, branches of right hepatic artery and right portal vein clinging to gallbladder infundibulum are often observed due to gallbladder infundibulum adhered to right hepatic hilum. The intraoperative damage of branches of right hepatic artery occurs more easily than that of bile duct, all of which are hidden pitfalls for surgeons. Magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) are the preferable tools for the diagnosis of Mirizzi syndrome. Anterograde cholecystectomy in Mirizzi syndrome is easy to damage branches of right hepatic artery and bile duct due to gallbladder infundibulum adhered to right hepatic hilum. Subtotal cholecystectomy is an easy, safe and definitive approach to Mirizzi syndrome. When combined with the application of ERCP, a laparoscopic management of Mirizzi syndrome by well-trained surgeons is feasible and safe. The objective of this review was to highlight its existing problems: (1) low preoperative diagnostic rate, (2) easy to damage bile duct and branches of right hepatic artery, and (3) high concomitant gallbladder carcinoma. Meanwhile, the review aimed to discuss the possible therapeutic strategies: (1) to enhance its preoperative recognition by imaging findings, and (2) to avoid potential pitfalls during surgery.

Evaluating Patient Satisfaction and Quality of Life After Undergoing Laparoscopic Cholecystectomy in Al-Qunfudhah Governorate, Saudi Arabia

BACKGROUND

Gallstone disease, commonly referred to as cholelithiasis, is a prevalent medical condition that has substantial global implications. Due to its numerous benefits, such as cheaper costs and shorter hospital stays, laparoscopic cholecystectomy (LC) has replaced open surgery as the most often performed surgical method for treating a range of biliary problems in wealthy countries. Any medical procedure's long-term patient well-being must be assessed, starting with the quality of life (QoL), patient satisfaction, and postoperative healing.

AIM

The current study aims to evaluate patient satisfaction and QoL after undergoing LC in Al-Qunfudhah Governorate.

METHODS

 A cross-sectional study was conducted targeting all patients who underwent LC in Al-Qunfudhah Governorate during the period from January to March 2024. The online survey was initiated by the study researchers after an intensive literature review and experts' consultation. The validated questionnaire was uploaded online using Google Forms and distributed electronically via social media apps.

RESULTS

The current study included records of 200 participants where the highest proportion falls within the 26 to 35 age group, comprising 57 individuals (28.5%). In terms of gender, males represent the majority, with 109 participants (54.5%). A total of 122 individuals (61.0%) reported being satisfied with their procedures. Conversely, 18 patients (9.0%) expressed dissatisfaction. The majority of participants under investigation expressed satisfaction with their overall QoL after undergoing LC, with 84 patients (42.0%) reporting satisfaction and 67 patients (33.5%) reporting being very satisfied. Additionally, only a small proportion of participants expressed dissatisfaction or very dissatisfaction Conclusion: In summary, the current study demonstrated high satisfaction with the LC treatment and highly reported QoL, which were mostly attributable to a number of factors such as the staff's cooperation, the lack of severe problems, and the sufficiency of the pre-surgery information supplied.

Successful endoscopic laser lithotripsy in 2 cases of Bouveret syndrome and cholecystocolonic fistulae-induced colonic obstruction: a minimally invasive approach

Video 1Two successful cases of endoscopic treatment for Bouveret syndrome and gallstone ileus are shown, including imaging and endoscopic videos. Endoscopy is favored over surgery due to lower morbidity and mortality rates. Laser lithotripsy offers precision and minimal tissue damage.

The Diagnosis and Treatment of Acute Cholecystitis: A Comprehensive Narrative Review for a Practical Approach

Acute cholecystitis (AC), generally associated with the presence of gallstones, is a relatively frequent disease that can lead to serious complications. For these reasons, AC warrants prompt clinical diagnosis and management. There is general agreement in terms of considering early laparoscopic cholecystectomy (ELC) to be the best treatment for AC. The optimal timeframe to perform ELC is within 72 h from diagnosis, with a possible extension of up to 7-10 days from symptom onset. In the first hours or days after hospital admission, before an ELC procedure, the patient's medical management comprises fasting, intravenous fluid infusion, antimicrobial therapy, and possible administration of analgesics. Additionally, concomitant conditions such as choledocholithiasis, cholangitis, biliary pancreatitis, or systemic complications must be recognized and adequately treated. The importance of ELC is related to the frequent recurrence of symptoms and complications of gallstone disease in the interval period between the onset of AC and surgical intervention. In patients who are not eligible for ELC, it is suggested to delay surgery at least 6 weeks after the clinical presentation. Critically ill patients, who are unfit for surgery, may require rescue treatments, such as percutaneous or endoscopic gallbladder drainage (GBD). A particular treatment approach should be applied to special populations such as pregnant women, cirrhotic, and elderly patients. In this review, we provide a practical diagnostic and therapeutic approach to AC, even in specific clinical situations, based on evidence from the literature.

Research on the prognostic value of adjusting intraperitoneal three-dimensional quality evaluation mode in laparoscopic cholecystectomy patients

BACKGROUND

Benign gallbladder diseases have become a high-prevalence condition not only in China but also worldwide. The main types of benign gallbladder diseases include gallbladder polyps, acute and chronic cholecystitis, and gallstones, with gallstones being the most common, accounting for over 70% of cases. Although the mortality rate of benign gallbladder diseases is low, they carry obvious potential risks. Studies have shown that an increased incidence of benign gallbladder diseases can increase the risk of cardiovascular diseases and gallbladder cancer, resulting in a substantial disease burden on patients and their families.

AIM

To assess the medical utility of the Configuration-Procedure-Consequence (CPC) three-dimensional quality evaluation model in modulating the prognosis of laparoscopic cholecystectomy patients.

METHODS

A total of 98 patients who underwent laparoscopic cholecystectomy in our hospital from February 2020 to January 2022 were selected as the subjects. According to the random number table method, they were divided into a study group and a control group, with 49 patients in each group. The control group received routine perioperative care, while the study group had the addition of the CPC three-dimensional quality evaluation. The postoperative recovery-related indicators (time to first flatus, time to oral intake, time to ambulation, hospital stay), stress indicators (cortisol and adrenaline levels), distinctions in anxiety and depression status, and the incidence of perioperative complications were compared.

RESULTS

The time to first flatus, time to oral intake, time to ambulation, and hospital stay of the study group patients were obviously lower than those of the control group patients, with statistical significance (P < 0.05). On the 1st day after admission, there were no obvious distinctions in cortisol and adrenaline levels in blood samples, as well as in the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores between the study group and the control group (P > 0.05). However, on the 3rd day after surgery, the cortisol and adrenaline levels, as well as SAS and SDS scores of the study group patients, were obviously lower than those of the control group patients (P < 0.05). The study group had 2 cases of incisional infection and 1 case of pulmonary infection, with a total incidence of complications of 6.12% (3/49), which was obviously lower than the 20.41% (10/49) in the control group (P < 0.05).

CONCLUSION

Implementing the CPC three-dimensional quality evaluation model for patients undergoing laparoscopic cholecystectomy can help accelerate their perioperative recovery process, alleviate perioperative stress symptoms, mitigate anxiety, depression, and other adverse emotions, and to some extent, reduce the incidence of perioperative complications.

Mirizzi syndrome: The Trojan horse of gallbladder disease

Background

The incidence of Mirizzi Syndrome ranges from 0.05 to 5.7 % of patients who undergo cholecystectomy. The purpose of this study is to examine the preoperative workup and postoperative outcomes for patients diagnosed with Mirizzi Syndrome.

Methods

Retrospective chart review was conducted between January 2018 and January 2022 at a single institution. All adult patients who underwent cholecystectomy were included.

Results

1628 patients underwent cholecystectomy of which 47 were diagnosed with Mirizzi Syndrome. The majority of patients had type 1 Mirizzi Syndrome. Preoperative studies were often nondiagnostic and 81 % of cases were diagnosed intraoperatively. 66 % of cases were performed laparoscopically, an open approach was required for type V Mirizzi Syndrome. The complication rate was 25 %; most commonly a bile leak requiring ERCP.

Conclusion

Mirizzi syndrome is more common than previously expected and related to patient's ability to seek timely medical care. Most cases can be completed laparoscopically however there is a high rate of complications.

Key message

This study presents an additional cohort of patients found to have Mirizzi syndrome and supports the hypothesis that it is difficult to diagnose preoperatively. Cases should be attempted laparoscopically but there remains a high complication rate.

Treatment of Bouveret syndrome with stone fragmentation using an endoscopic submucosal dissection knife

Video 1Treatment of Bouveret syndrome with stone fragmentation using an endoscopic submucosal dissection knife. A 61-year-old man with a 3-decade history of recurrent cholecystitis presented to the community emergency department with severe right upper quadrant pain. A CT scan was performed and revealed gangrenous cholecystitis with likely cholecystoduodenal fistulous communication.After discussion with the patient and the HPB team, the plan was made to attempt endoscopic extraction of the obstructing stone. This would be performed in the operating room, such that if endoscopic extraction was not possible, surgical management would proceed.During the endoscopy, 1 L of liquid material was suctioned and the retained solids were cleared as best as possible. The large obstructing stone was then seen in the duodenal cap. In the cap, we could appreciate the obstructing stone and the fistulous tract.We then passed a guidewire distal to the stone and advanced a 15- to 20-mm extraction balloon over the guidewire. The balloon was passed distal to the stone and inflated to 20 mm. We then applied firm, steady traction in an attempt to extract the stone.With the double-channel gastroscope, we passed a second wire and extraction balloon distal to the stone to increase the amount of traction that could be applied. Both balloons were inflated distal to the stone, and steady, firm traction was again applied. Unfortunately, this was not successful either.We then decided to use a regular ERCP needle knife to incise the stone. Because the knife was delicate, it was easily deformable, so we decided to switch to a triangle-tip knife.Using the "PreciseSECT" mode on the electrosurgical unit, the stone was repeatedly incised. Particular care was taken to avoid flinging the knife and damaging the duodenal wall.Saline was used as the irrigation solution to ensure electrosurgical conductivity when the current was applied.At this point, we could appreciate fragmentation of the stones after repeated incision.After about 3 hours of stone incision and fragmentation, the guidewire was passed beyond the stone; the extraction balloon was advanced over the wire; and the balloon was again inflated with steady traction applied. This time, the stone was successfully extracted from the stomach.The duodenum was then examined. There were no remaining large pieces of stone or any significant mucosal damage or perforation.Using a mechanical lithotripter, the remaining larger fragments of stone were fragmented and extracted. However, because the stone had a large diameter, lithotripsy at the center was not initially possible, and the smaller lateral aspects had to be performed until the stone was completely fragmented.This case demonstrates the incision and fragmentation of a massive gallstone with the use of an endoscopic submucosal dissection knife and electrosurgical unit.With cautious application of this technique, successful endoscopic management of a large gallstone causing Bouveret syndrome was achieved. This technique avoided open surgical management and allowed for elective cholecystectomy at a later date with less morbidity.

Mirizzi Syndrome-The Past, Present, and Future

Mirizzi syndrome is a complication of gallstone disease caused by an impacted gallstone in the infundibulum of the gallbladder or within the cystic duct, causing chronic inflammation and extrinsic compression of the common hepatic duct or common bile duct. Eventually, mucosal ulceration occurs and progresses to cholecystobiliary fistulation. Numerous systems exist to classify Mirizzi syndrome, with the Csendes classification widely adopted. It describes five types of Mirizzi syndrome according to the presence of a cholecystobiliary fistula and its corresponding severity, and whether a cholecystoenteric fistula is present. The clinical presentation of Mirizzi syndrome is non-specific, and patients typically have a longstanding history of gallstones. It commonly presents with obstructive jaundice, and can mimic gallbladder, biliary, or pancreatic malignancy. Achieving a preoperative diagnosis guides surgical planning and improves treatment outcomes. However, a significant proportion of cases of Mirizzi syndrome are diagnosed intraoperatively, and the presence of dense adhesions and distorted anatomy at Calot's triangle increases the risk of bile duct injury. Cholecystectomy remains the mainstay of treatment for Mirizzi syndrome, and laparoscopic cholecystectomy is increasingly becoming a viable option, especially for less severe stages of cholecystobiliary fistula. Subtotal cholecystectomy is feasible if total cholecystectomy cannot be performed safely. Additional procedures may be required, such as common bile duct exploration, choledochoplasty, and bilioenteric anastomosis. Conclusions: There is currently no consensus for the management of Mirizzi syndrome, as the management options depend on the extent of surgical pathology and availability of surgical expertise. Multidisciplinary collaboration is important to achieve diagnostic accuracy and guide treatment planning to ensure good clinical outcomes.

Double Trouble: A Case of Gallstone Ileus as a Result of Multiple Obstructive Gallstones

Gallstone ileus is a rare condition. It accounts for approximately 1% of small bowel obstruction and is more prevalent in the elderly population. It is usually present in relatively comorbid patients posing further operative challenges. The following report investigates the management of two large gallstones resulting in two different points of obstruction. Is double trouble doubly hard to manage?

Diseases of the Gallbladder and Biliary Tree

Diseases of the gallbladder include a spectrum of gallstone diseases (cholelithiasis, cholecystitis, choledocholithiasis, and cholangitis), cysts, polyps, and malignancy. In this review, we present the incidence, risk factors, clinical presentation, diagnosis, and treatment of these various conditions. Importantly, we report when more urgent referral is indicated, as well as red flags that warrant further intervention and/or management.

Use of Percutaneous Cholecystostomy for the Management of Complicated Cholecystitis Causing Gastric Outlet Obstruction in an Elderly Patient

The management of complicated cholecystitis in an elderly patient can present a complex clinical decision for surgeons. There is literature supporting the use of immediate laparoscopic cholecystectomy for cases of uncomplicated cholecystitis in elderly patients and complicated cholecystitis in the general population. There are, however, no clear guidelines for treating the unique presentation of an elderly patient with complicated cholecystitis. This is likely due to the many clinical risk factors that must be considered when caring for these complex patients often with many medical comorbidities. In this report, we present the case of an 81-year-old male with complicated chronic cholecystitis leading to the exceedingly rare complication of gastric outlet obstruction. The patient was successfully treated with percutaneous cholecystostomy tube placement and interval subtotal laparoscopic cholecystectomy.

Abdominal Pain and Hypotension in a 70-Year-Old Woman

A 70-year-old woman with hypertension, atrial fibrillation, congestive heart failure, and gallstones had 3 days of nausea, vomiting, and abdominal pain. Abdominal computed tomography showed a thickened gallbladder wall with intraluminal air adherent to the duodenum and a gallstone in the middle ileum with proximal bowel distension. What is the diagnosis and what would you do next?

Bouveret Syndrome simultaneous with an incidental solitary Gastric Neuroendocrine Tumor in a 44-year-old female - A Case Report

Bouveret Syndrome (BS) is a rare type of gallstone ileus, where a gallstone passes via a cholecystoduodenal fistula and causes gastric outlet obstruction. It comprises 0.3-0.5% of cholelithiasis complications. It primarily affects females with an average incidence age of 74 years. Gastric Neuroendocrine Tumors (G-NETs) make up merely 2% of all forms of gastric neoplasia and are known to be an extremely rare occurrence. Their annual incidence is estimated to be one to two per 1 million individuals, and they comprise 8.7% of all known neuroendocrine neoplasia of the gastrointestinal system.

Case presentation

We present the case of a 44-year-old Middle Eastern female who presented to the clinic due to multiple episodes of food containing biliary nonprojectile emesis accompanied by epigastric pain. Preoperative radiological workup revealed a Bezoar blocking the gastric outlet and a G-NET in the mucosal layer of the stomach.

Clinical discussion

Surgical intervention consisted of excising the impacted calculus to relieve the existing gastric outlet obstruction simultaneous to performing an uncut Roux-en-Y to treat the G-NET condition. The patient underwent complete recovery.

Conclusion

BS is an extremely rare form of gallstone ileus and gastric outlet obstruction. Its clinical presentation is nonspecific and results in misdiagnosis. Additionally, it is rare to occur in our patient's age group. NETs are also profoundly rare forms of neoplasia. To the best of our knowledge, no previous cases of simultaneous BS and G-NET have been documented. Therefore, clinical awareness should be raised to timely implement the necessary therapeutic interventions.

A rarer cause of Bouveret syndrome - A case report

INTRODUCTION AND IMPORTANCE

Bouveret syndrome is a rare type of gallstone ileus causing gastric outlet obstruction with high morbidity and mortality risk, and hence important to have a high degree of clinical suspicion on presentation for prompt diagnosis and management.

CASE PRESENTATION

We present a case of an elderly woman with abdominal pain, haematemesis, and an unremarkable radiograph whose initial emergent endoscopy showed a gastric obstruction and a duodenal diverticulum with a non-bleeding broad based duodenal ulcer. Subsequent computerised tomographic (CT) scan revealed a cholecystoduodenal fistula and gastric outlet obstruction secondary to a 5 cm stone in the duodenojejunal (DJ) flexure. A repeat endoscopy was attempted for endoscopic removal prior to proceeding to open enterolithotomy.

CLINICAL DISCUSSION

This case highlights the challenges in diagnosis and discusses the latest literature on multimodal management consisting of endoscopy and surgery.

CONCLUSION

The location of the obstructing stone at the duodenojejunal flexure is extremely rare and therefore will add to world literature on Bouveret syndrome.

An unusual case of mechanical bowel obstruction due to cholecysto-intestinal fistula and impacted gallstone: A case report and literature review

Gallstone ileus is a rare entity and constitutes an uncommon complication of gallstone disease. It is caused by the impaction of a gallstone in the gastrointestinal tract and may cause serious symptoms or even life-threatening complications. It should be part of the differential diagnosis of acute abdomen especially in patients presenting with signs and symptoms of bowel obstruction and known gallstone disease. An early diagnosis is essential, and surgical treatment is the gold standard in order to relieve the obstruction. We present the case of an 84-year-old male patient with gallstone ileus due to cholecysto-intestinal fistula and impacted gallstone at jejunum. He was treated via urgent enterolithotomy, and his post-operative period was uneventful. This report aims to further educate clinical doctors on this rare medical condition which may pose a potentially serious health risk.

Multiparameter diagnostic model based on 18F-FDG PET metabolic parameters and clinical variables can differentiate nonmetastatic gallbladder cancer and cholecystitis

OBJECTIVE

To evaluate the diagnostic value of a multiparameter model based on ¹⁸F-fluorodeoxyglucose positron emission tomography (¹⁸F-FDG PET) metabolic parameters and clinical variables in differentiating nonmetastatic gallbladder cancer (GBC) from cholecystitis.

PATIENTS AND METHODS

In total, 122 patients (88 GBC nonmetastatic patients and 34 cholecystitis patients) with gallbladder space-occupying lesions who underwent ¹⁸F-FDG PET/CT were included. All patients received surgery and pathology, and baseline characteristics and clinical data were also collected. The metabolic parameters of ¹⁸F-FDG PET, including SUVmax (maximum standard uptake value), SUVmean (mean standard uptake value), SUVpeak (peak standard uptake value), MTV (metabolic tumour volume), TLG (total lesion glycolysis) and SUVR (tumour-to-normal liver standard uptake value ratio), were evaluated. The differential diagnostic efficacy of each independent parameter and multiparameter combination model was evaluated using the receiver operating characteristic (ROC) curve. The improvement in diagnostic efficacy using a combination of the above multiple parameters was evaluated by integrated discriminatory improvement (IDI), net reclassification improvement (NRI) and bootstrap test. Decision curve analysis (DCA) was used to evaluate clinical efficacy.

RESULTS

The ROC curve showed that SUVR had the highest diagnostic ability among the ¹⁸F-FDG PET metabolic parameters (area under the curve [AUC] = 0.698; sensitivity = 0.341; specificity = 0.971; positive predictive value [PPV] = 0.968; negative predictive value [NPV] = 0.363). The combined diagnostic model of cholecystolithiasis, fever, CEA > 5 ng/ml and SUVR showed an AUC of 0.899 (sensitivity = 0.909, specificity = 0.735, PPV = 0.899, NPV = 0.758). The diagnostic efficiency of the model was improved significantly compared with SUVR. The clinical efficacy of the model was confirmed by DCA.

CONCLUSIONS

The multiparameter diagnostic model composed of ¹⁸F-FDG PET metabolic parameters (SUVR) and clinical variables, including patient signs (fever), medical history (cholecystolithiasis) and laboratory examination (CEA > 5 ng/ml), has good diagnostic efficacy in the differential diagnosis of nonmetastatic GBC and cholecystitis.

Surgical Management of Cholecystoenteric Fistula in Patients With and Without Gallstone Ileus: An Experience of 29 Cases

Background

Cholecystoenteric fistula (CEF) is an uncommon complication of cholelithiasis. Here, we report our experience on diagnostic methods and surgical management of CEF patients with and without gallstone ileus (GI).

Methods

This is a retrospective cases series over an 11-year period (2011–2022). Data analyzed included preoperative characteristics, ultrasound, imaging features, operation findings and postoperative course.

Results

A total of 29 patients diagnosed with CEF were enrolled, 51.7% (15/29) of whom were female, with a median age of 66 years (range: 35–96 years). With regards to subtype distribution, seventeen patients had cholecystoduodenal fistula (CDF), six had cholecystoconlonic fistula (CCF), three exhibited cholecystogastric fistula (CGF), one CDF combination with CCF and two CDF combination with type I Mirizzi syndrome. Twelve patients presented with gallstone ileus, and received one stage procedure or simple Enterolithotomy. The median operation time and blood loss of 157 min (range: 65–360 min) and 40 ml (range: 10–450 ml), respectively. Surgical complications, evidenced by fistula recurrence, were recorded in three patients (3/22; 13.6%), while four (4/29; 13.8%) and one patient (1/29; 3.4%) presented with wound infection and residual stone in common bile duct, respectively. No deaths were reported in our study.

Conclusion

CEF is a rare complication of gallstone disease that is occasionally found during operation. To date, no consensus has been reached regarding efficacious treatment therapies for CEF patients. For a CEF patient with GI, one stage procedure should be selected prudently, while simple Enterolithotomy would be a mainstream choice for relieving bowel obstruction.

Minimally invasive management of Mirizzi syndrome Va: Case series and narrative review of the literature

INTRODUCTION

Mirizzi's Syndrome (MS) is a rare pathology, known to be a challenge for the surgeon. In the surgical management, open approach vs laparoscopic is a topic of discussion due to anatomic variations. The aim of this study is to analyze our experience in the laparoscopic management of this condition in Type Va.

METHODS

We made a descriptive retrospective study of patients diagnosed with MS type Va and treated by laparoscopic approach from 2014 to 2019, in two high volume centers of Bogotá, Colombia.

RESULTS

1073 patients who presented complications from gallstones were evaluated, of which 16 were diagnosed with MS type Va. 75% were females and 25% males; 80% presented jaundice and 90% abdominal pain; 12 patients showed cholecystoduodenal fistula and 4 cholecystocolic fistula. All patients underwent laparoscopic management, total cholecystectomy and fistula resection with primary closure was possible on a 100% of the patients. Conversion rate was 0%. The follow up was 18 months.

CONCLUSION

Laparoscopic management of MS is feasible and safe; the experience of the surgery group and selection of the patients is the key to a successful outcome.

Type IV Mirizzi Syndrome: Brief Report and Review of Management Options

Mirizzi syndrome is a rare complication of chronic calculous cholecystitis. Preoperative diagnosis is challenging due to the absence of pathognomonic signs and symptoms and low sensitivity rates of imaging tests. Historically, laparotomy has been the preferred choice of surgical management. Endoscopic and laparoscopic approaches have been increasingly described as diagnostic and therapeutic options for Mirizzi type I and II, but data is limited regarding the management of more complex cases. We describe a staged endoscopic and laparoscopic approach for the management of type IV Mirizzi syndrome and review the management options.

Bouveret Syndrome: A Rare Case and Review of the Literature

Bouveret syndrome is a subtype of gallstone ileus, wherein a calculus becomes entrapped in the duodenum via a cholecystocolic fistula, leading to gastric outlet obstruction. Due to the non-specific symptoms the patients present with, a diagnosis is reliant on computed tomography (CT), magnetic resonance imaging (MRI) or direct endoscopic visualisation. We report a case of Bouveret syndrome and review current literature, outlining the aetiopathogenesis and management strategies of this condition.

Indocyanine green fluorescence: A surgeon's tool for the surgical approach of gallstone ileus

Fluorescence cholangiography has been shown to improve biliary anatomy identification. A case of 60-year-old man with intestinal obstruction is reported, an entero-biliary fistula is suspected, and intravenous application of indocyanine green is decided, despite the great inflammatory process and fibrotic tissues found during the procedure, safe open cholecystectomy was achieved.

Beyond acute cholecystitis-gallstone-related complications and what the emergency radiologist should know

The purpose of this study is to emphasize the imaging features of complications of gallstones beyond the cystic duct on ultrasound (US), enhanced and nonenhanced computed tomography (CECT and NECT), magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP). This article includes a brief overview of gallstone imaging and emerging trends in the detection of gallstones. This review article will highlight complications of gallstones, including choledocholithiasis, gallstone pancreatitis, acute cholangitis, Mirizzi syndrome, cholecystobiliary and cholecystoenteric fistulas, and gallstone ileus. Imaging findings and limitations of US, CT, MRI, and ERCP will be discussed. The review article will also briefly discuss the management of each disease. The presence of gallstones beyond the level of the cystic duct can lead to a spectrum of diseases, and emergency radiologists play a critical role in disease management by providing a timely diagnosis. Documenting the location of a gallstone within the common bile duct (CBD) in symptomatic cholelithiasis and the presence of acute interstitial edematous pancreatitis and/or ascending cholangitis plays a pivotal role in disease management. Establishing the presence of ectopic gallstones and biliary-enteric fistulae has a significant role in directing patient management.

Gas in the Portal Vein: An Emergency or Just Hot Air?

We report the case of a 87-year-old woman admitted to our Emergency Department for mild abdominal pain associated with vomiting. An abdominal X-ray showed gas present in the portal venules of the left hepatic lobe, a finding associated with numerous surgical and medical conditions. The patient was successfully managed with conservative treatment. Isolated intrahepatic gas is a rare radiologic finding; emergency surgery should be performed only when there are signs of associated acute intestinal infarction.

Gallbladder Torsion Masking as Acalculus Cholecystitis: A Review of Two Cases Including Unsuccessful Management With Percutaneous Cholecystostomy

Gallbladder torsion is a rare cause of abdominal pain; however, it is important to diagnose pre-operatively. We report two cases of gallbladder torsion, both of which were not recognized until the time of surgery. Both patients were elderly thin females, presenting with right upper quadrant pain, and on examination had a positive Murphy’s sign, and pre-operative imaging was suggestive of acalculus cholecystitis. One patient was initially managed by percutaneous insertion of a cholecystostomy tube, with progression to a laparoscopic cholecystectomy after a failure of resolution of symptoms. The second patient was taken to theater shortly after presentation, with the gallbladder torsion recognized intra-operatively. In both cases, the gallbladder was distorted and a routine laparoscopic cholecystectomy was performed with good recovery following. These two cases highlight the need for gallbladder torsion to be considered as a diagnostic possibility in those presenting with right upper quadrant pain, particularly those groups at most risk, including elderly thin females. Whilst other causes of cholecystitis can be managed non-operatively, at least in the acute phase, gallbladder torsion requires urgent operative intervention.

Gallstone ileus associated with cholecystogastric fistula: Case report, diagnosis and surgical treatment

Introduction

Gallstone Ileus is a rare complication of cholelithiasis, associated with multiple episodes of cholecystitis, with the formation of adhesions and fistulas between the gallbladder and adjacent organs. Its diagnosis is difficult, requiring complementary imaging tests such as computed tomography or radiography.

Presentation of case

Female patient, with intestinal obstruction for 7 days, associated with abdominal pain and previous episodes of pain in the right hypochondrium for 3 months. Abdominal CT scan identified aerobilia, gallstone impacted in the ileocecal valve and small loop dilatation, in addition to a probable cholecystogastric fistula. Opted for exploratory laparotomy, enterolithotomy and fistula correction in one surgical time.

Discussion

Gallstone ileus is rare among the complications of cholelithiasis, in addition to the fact that cholecystogastric fistula is associated with gastric pylorus obstruction and not impaction on the ileocecal valve. Imaging tests are useful to complement the diagnosis, and if Rigler's triad is present, the suspicion of gallstone ileus is increased. The presence of fistula between the gallbladder and stomach presents a frequency between 0 and 13.3%. There is no gold standard treatment for gallstone ileus, but surgery options for each type of patient and severity level.

Conclusion

There is no definitive protocol for optimal surgical treatment for biliary ileus, but the possibility of enterolithotomy associated with cholecystectomy and fistula correction can be evaluated in selected patients.

•

Gallstone ileus is a rare cause of intestinal obstruction.

•

Cholecystogastric fistula may be associated with ileum obstruction.

One-step surgical treatment can be used in specific patients

Laparoscopic management of gallstone ileus: A case report and literature review

Introduction and importance

Gallstone ileus is an uncommon complication of cholelithiasis. It is usually presented as a small bowel obstruction. Elderly patients are commonly affected. The diagnosis is challenging, since needs a high index of suspicion and imagenology is key. Surgery is the mainstay management, most commonly performed by laparotomy, but laparoscopy is summing cases. Nevertheless the approach is still controversial. We report a gallstone ileus case, that was managed totally laparoscopic in our medium complex public institution.

Case presentation

An 71 years-old male patient, with symptomatic cholelithiasis, consulted in emergency department with symptoms and signs of small bowel obstruction. Computed tomography of abdomen and pelvis showed the classical Rigler's triad. Totally laparoscopic enterolithotomy alone was performed successfully. Postoperative evolution was without incidents, being discharge at fifth day.

Clinical discussion

Gallstone ileus represents around 0,3–0,5% of cholelithiasis complications. Mostly affect elderly women patients, with comorbidities. Mortality and morbidity is still high nowadays. The classical management of gallstone ileus is the open surgery, but the laparoscopic approach has been described and it can be done.

Conclusion

The laparoscopic management of gallstone ileus is effective and secure procedure and seems reasonable to attempt if the conditions and skills are available.

Surgical outcome of Mirizzi syndrome: Value of endoscopic retrograde cholangiopancreatography and laparoscopic procedures

BACKGROUND

Laparoscopic cholecystectomy (LC) with associated procedures and endoscopic retrograde cholangiopancreatography (ERCP) have been the standard treatments for both common and rare biliary diseases. Mirizzi syndrome (MS) is a rare and complex biliary condition. We report our experience with MS treatment and investigate the value of laparoscopic procedures and ERCP in patient management.

METHODS

From 2004 to 2017, 100 consecutive patients with MS were diagnosed by ERCP and underwent surgery in a referral center. Sixty patients were treated with intended LC, and 40 patients were treated with open cholecystectomy (OC). The clinical manifestations, ERCP and associated procedures, surgical procedures, and postoperative outcomes were investigated.

RESULTS

The surgical mortality rate was 1%, while the surgical morbidity rate was 15%. The patients treated with intended LC suffered from less morbidity (5%). The percentage of postoperative residual biliary stones was 32% (n = 32), and only three patients underwent re-operation (laparotomy) for stone removal. The laparotomy conversion rate in the intended LC group was 16.7% (10/60). The length of hospitalization for the patients with successful LC was significantly shorter than that for the patients with conversion and intended OC. Csendes classification was a risk factor for conversion from LC to OC (type I vs types II to V, P < .0001).

CONCLUSIONS

A combination of a laparoscopic procedure and ERCP may provide therapeutic benefits for patients with MS.

Minimally invasive management of Mirizzi syndrome Va: Case series and narrative review of the literature

INTRODUCTION

Mirizzi's Syndrome (MS) is a rare pathology, known to be a challenge for the surgeon. In the surgical management, open approach vs laparoscopic is a topic of discussion due to anatomic variations. The aim of this study is to analyze our experience in the laparoscopic management of this condition in Type Va.

METHODS

We made a descriptive retrospective study of patients diagnosed with MS type Va and treated by laparoscopic approach from 2014 to 2019, in two high volume centers of Bogotá, Colombia.

RESULTS

1073 patients who presented complications from gallstones were evaluated, of which 16 were diagnosed with MS type Va. 75% were females and 25% males; 80% presented jaundice and 90% abdominal pain; 12 patients showed cholecystoduodenal fistula and 4 cholecystocolic fistula. All patients underwent laparoscopic management, total cholecystectomy and fistula resection with primary closure was possible on a 100% of the patients. Conversion rate was 0%. The follow up was 18 months.

CONCLUSION

Laparoscopic management of MS is feasible and safe; the experience of the surgery group and selection of the patients is the key to a successful outcome.

The Use of Bedside Ultrasound for Gallstone Disease Care within a Community-based Emergency Department: A Confirmation Bias

INTRODUCTION

Traditional evaluation for suspicion of gallstone or gallbladder-related disease includes evaluation with a formal technician-performed ultrasound. However, the use of point-of-care bedside ultrasounds (Bedside US) has been shown to be a viable alternative for the diagnosis of gallstones and gallbladder-related diseases. Purpose Statement: The purpose of this study was to evaluate the impact of Bedside US use in gallbladder evaluation on key patient care outcomes within our community-based emergency department setting.

METHODS

This retrospective study compared the use of no ultrasound (No US), a formal technician performed ultrasound (Tech US) and Bedside US for gallstone and gallbladder related diseases within a community hospital emergency department between January 1, 2015 and January 1, 2018. Initial vitals, lab work, patient socio-demographics, medical history, emergency department length of stay in hours and disposition were reviewed.

RESULTS

Of a total N = 449 patients included, patients who received a Bedside US had the fewest computerized tomography scans (No US 62% vs. Tech US 29% vs. Bedside US 16%; p < 0.0001), the shortest median emergency department length of stay (No US 4.5 days vs. Tech US 5.0 days vs. Bedside US 3.0 days; p < 0.0001), and were more likely to be discharged home (No US 41% vs. Tech US 55% vs. Bedside US 81%; p = 0.0006) compared to those that received no ultrasound or a formal ultrasound. Patients who received a Bedside US also had the statistically significant highest incidence of prior cholelithiasis (No US 29.4% vs Tech US 14.3% vs. Bedside US 31.3%; p = 0.001) and lowest total median bilirubin levels (No US 0.5 vs. Tech US 0.5 vs. Bedside US 0.3; p = 0.016) when compared to the other two groups.

CONCLUSIONS

Although there was a confirmation bias, these study results indicate that point-of-care bedside ultrasound could be a viable alternative for gallstones and gallbladder-related diseases with benefits of use in a community hospital setting.

Upper Gastrointestinal Bleeding: A Potential Precursor to Bouveret's Syndrome

Bouveret's syndrome is a rare complication of cholelithiasis. It is characterized by a gallstone entering the intestine through a cholecystoenteric fistula, impacting the duodenum and causing gastric outlet obstruction. Rarely, it presents with hematemesis and melena. The diagnosis involves computed tomography (CT) and the treatment depends on the patient's stability, the location of the obstruction, stone size, and the fistula. Endoscopy or minimally invasive lithotripsy can be considered initially. If this fails, surgical intervention is recommended. We present a case of upper gastrointestinal bleeding (UGIB) preceding the development of Bouveret's syndrome.

Role of Prophylactic Cholecystectomy After Endoscopic Sphincterotomy for Biliary Stone Disease: A Systematic Review and Meta-analysis

OBJECTIVE

The aim of this study was to perform a structured systematic review and meta-analysis to evaluate the effectiveness and complication rate of cholecystectomy deferral versus prophylactic cholecystectomy among patients post-endoscopic biliary sphincterotomy for common bile duct stones.

BACKGROUND

Although previous reports suggest a decreased risk of biliary complications with prophylactic cholecystectomy, biliary endoscopic cholangiopancreatography (ERCP) with sphincterotomy may provide a role for deferring cholecystectomy with the gallbladder left in situ.

METHODS

Searches of PubMed, EMBASE, Web of Science, and Cochrane Library databases were performed through August 2019 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Meta-Analysis of Observational Studies in Epidemiology guidelines. Measured outcomes included: mortality, recurrent biliary pain or cholecystitis, pancreatitis, cholangitis, and eventual need for cholecystectomy. Random effects models were used to determine pooled effect size and corresponding 95% confidence intervals (CIs).

RESULTS

Nine studies (n = 1605) were included. A total of 53.8% (n = 864) patients had deferred cholecystectomy post-sphincterotomy. Deferral cholecystectomy as compared to prophylactic cholecystectomy resulted in a significant increased risk of mortality [odds raio (OR) 2.56 (95% confidence interval, CI 1.54-4.23); P < 0.0001; I2 = 18.49]. Patients who did not undergo prophylactic cholecystectomy developed more recurrent biliary pain or cholecystitis [OR 5.10 (95% CI 3.39-7.67); P < 0.0001; I2 = 0.00]. Rate of pancreatitis [OR 3.11 (95% CI 0.99-9.83); P = 0.053; I2 = 0.00] and cholangitis [OR 1.49 (95% CI 0.74-2.98); P = 0.264; I2 = 0.00] was unaffected. Overall, 26.00% (95% CI 14.00-40.00) of patients with deferred prophylactic cholecystectomy required eventual cholecystectomy.

CONCLUSIONS

Prophylactic cholecystectomy remains the preferred strategy compared to a deferral approach with gallbladder in situ post-sphincterotomy for patients with bile duct stones. Future studies may highlight a subset of patients (ie, those with large balloon biliary dilation) that may not require cholecystectomy.

Gallstone ileus after recent cholecystectomy. Case report and review of the literature

INTRODUCTION AND IMPORTANCE

Gallstone ileus in cholecystectomized patients is very infrequent and when it happens shortly after surgery is even rarer. We report the case of a patient who presented Gallstone ileus few days after open cholecystectomy which has not been reported before in literature.

CASE PRESENTATION

A 52-year-old male with a history of recent open cholecystectomy was referred to our center due to a presumable surgical complication. During his hospitalization while trying to restart the oral route he presented abdominal pain and nausea. He evolved toward a bowel obstruction. We suspected gallstone ileus based on medical history as well as preoperative image study. We confirmed the diagnostic using a Computed Tomography. Surgical management was performed and a large gallstone was extracted from the bowel. The patient progressed favorably and was discharged. He was asymptomatic during the follow-up.

CLINICAL DISCUSSION

Cholecystectomized patients who have been reported with Gallstone ileus demonstrate different pathophysiological mechanisms or extraordinary presentations. This case describes a unique presentation illustrating relevant aspects of this pathology such as showing that acute cholecystitis can be its clinical manifestation or that it could happen after a cholecystoenteric fistula is found during a cholecystectomy.

CONCLUSION

Gallstone ileus in cholecystectomized patients is very rare. Clinical suspicion remains the cornerstone of diagnosis.

Biliary microbiota and mucin 4 impact the calcification of cholesterol gallstones

BACKGROUND

Cholesterol gallstones account for over 80% of gallstones, and the pathogenesis of gallstone formation involves genetic and environmental factors. However, data on the evolution of cholesterol gallstones with various densities are limited. This study aimed to determine the roles of microbiota and mucins on the formation of calcified cholesterol gallstones in patients with cholelithiasis.

METHODS

Paired gallbladder tissues and bile specimens were obtained from cholelithiasis patients who were categorized into the isodense group and calcified group according to the density of gallstones. The relative abundance of microbiota in gallbladder tissues was detected. Immunohistochemistry and enzyme-linked immunosorbent assay were performed to detect the expression levels of MUC1, MUC2, MUC3a, MUC3b, MUC4, MUC5ac and MUC5b in gallbladder tissues and bile. The correlation of microbiota abundance with MUC4 expression was evaluated by linear regression.

RESULTS

A total of 23 patients with gallbladder stones were included. The density of gallstones in the isodense group was significantly lower than that of the calcified group (34.20 ± 1.50 vs. 109.40 ± 3.84 HU, P < 0.0001). Compared to the isodense group, the calcified group showed a higher abundance of gram-positive bacteria at the fundus, in the body and neck of gallbladder tissues. The concentrations of MUC1, MUC2, MUC3a, MUC3b, MUC5ac and MUC5b in the epithelial cells of gallbladder tissues showed no difference between the two groups, while the concentrations of MUC4 were significantly higher in the calcified group than that in the isodense group at the fundus (15.49 ± 0.69 vs. 10.23 ± 0.54 ng/mL, P < 0.05), in the body (14.54 ± 0.94 vs. 11.87 ± 0.85 ng/mL, P < 0.05) as well as in the neck (14.77 ± 1.04 vs. 10.85 ± 0.72 ng/mL, P < 0.05) of gallbladder tissues. Moreover, the abundance of bacteria was positively correlated with the expression of MUC4 (r = 0.569, P < 0.05) in the calcified group.

CONCLUSIONS

This study showed the potential clinical relevance among biliary microbiota, mucins and calcified gallstones in patients with gallstones. Gram-positive microbiota and MUC4 may be positively associated with the calcification of cholesterol gallstones.

A Unique Presentation of Bouveret's Syndrome: Two Large Gallstones Obstructing Both the Gastric Outlet and the Common Bile Duct Simultaneously

Bouveret's syndrome refers to a gastric outlet obstruction secondary to impaction of a gallstone in the pylorus or proximal duodenum. Thus, it can be considered a very proximal form of gallstone ileus and is infrequent. We describe such a unique case that a female patient presents with Bouveret's syndrome and concomitant common bile duct obstruction by a second gallstone. The decision over its surgical management is complicated, based on risk factors, clinical presentations, radiographic evidence, surgical risk assessment, and specific considerations tailored to individual case. Because of her stable clinical picture and low surgical risk, we proceeded with stone extractions, fistula take-down, and common bile duct exploration in a one-stage procedure. Her postoperative course was complicated by bile stained drainage through closed suction drain that resolved with conservative management.

Gallstone ileus caused by a gallstone impacted at a cecum neoplasm - A case report

BACKGROUND

Gallstone ileus is an infrequent complication of biliary disease that produces a mechanical intestinal obstruction. It is caused by a gallstone passing through a bilio-digestive communication, usually a cholecystoduodenal fistula. The presence of neoplasms can decrease the bowel lumen size and may cause the gallstone to impact at the narrowing site.

CASE SUMMARY

In this report, we present a unique case of gallstone ileus due to a gallstone impacted in a cecum tumor, causing obstruction at the level of the ileocecal valve. The patient needed an urgent right hemicolectomy to solve both his problems. The gallbladder and the enterobiliary fistula remained in situ.

DISCUSSION

The clinical presentation is not always straightforward and sometimes the diagnosis is only made by imaging, mostly resorting to an abdominal CT. The mainstay of management is surgical relief of the gastrointestinal obstruction, with the surgical method being based on what is found intra-operatively and according to the patient general condition.

CONCLUSION

Although a rare disease, gallstone ileus should be suspected in elderly patients with intestinal obstruction and a previous history of biliary problems, keeping in mind that other conditions may be present and can alter the surgical treatment of choice.

Focus on management of gallstone ileus

Gallstone ileus is a rare form of intestinal obstruction and an uncommon complication of gallstone disease resulting from the impaction of one or more gallstones in the bowel owing to biliary intestinal fistula. The increasing incidence of gallstone ileus is related to the high prevalence of cholelithiasis, the aging of the population, and the more sensitive diagnostic tools. The diagnosis is often delayed due to the lack of typical clinical manifestations. In this paper, we discuss the pathogenesis of gallstone ileus, factors that result in its diagnosis, and therapeutic strategies by performing a systematic review of the literature. We also emphasize the specificity and complexity of gallstone ileus. We suggest that on the basis of observing the basic principles, the management should be rationalized and individualized in clinical practice so as to improve the prognosis of gallstone ileus.

Type III Mirizzi, successfully treated with a free gallbladder flap, a case report

BACKGROUND

Mirizzi syndrome is a type of biliary obstruction caused by an impacted stone in the gallbladder neck or cystic duct that causes and extrinsic obstruction of the common bile duct, this condition if left untreated can lead to duct erosion, fistula, and cholangitis. Preoperative diagnosis is difficult since if not diagnosed correctly can elevate the risk of intraoperative bile duct injury.

CASE PRESENTATION

We present the case of a 61-year-old patient, she presented to our hospital with obstructive jaundice, and a type III Mirizzi syndrome was identified. Preoperative diagnosis was completed, and she was successfully treated using a gallbladder free flap. On follow-ups, the patient is doing well.

CONCLUSION

Mirizzi Syndrome is a rare syndrome that can lead to anatomical disturbances and surgical difficulties due to the hostile territory it creates. High clinical awareness, an emphasis on the preoperative diagnosis, and safe surgical techniques minimizing bile duct injury can improve patients outcome.

Challenging biliary strictures: pathophysiological features, differential diagnosis, diagnostic algorithms, and new clinically relevant biomarkers - part 1

It is frequently challenging to make the correct diagnosis in patients with biliary strictures. This is particularly important as errors may have disastrous consequences. Benign-appearing strictures treated with stents may later be revealed to be malignant and unnecessary surgery for benign strictures carries a high morbidity rate. In the first part of the review, the essential information that clinicians need to know about diseases responsible for biliary strictures is presented, with a focus on the most recent data. Then, the characteristics and pitfalls of the methods used to make the diagnosis are summarized. These include serum biomarkers, imaging studies, and endoscopic modalities. As tissue diagnosis is the only 100% specific tool, it is described in detail, including techniques for tissue acquisition and their yields, how to prepare samples, and what to expect from the pathologist. Tricks to increase diagnostic yields are described. Clues are then presented for the differential diagnosis between primary and secondary sclerosing cholangitis, IgG4-related sclerosing cholangitis, cholangiocarcinoma, pancreatic cancer, autoimmune pancreatitis, and less frequent diseases. Finally, algorithms that will help to achieve the correct diagnosis are proposed.

Bouveret Syndrome: A Rare Case of Instance and Treatment in a Younger Patient

Bouveret syndrome, a specific form of gallstone ileus, is the obstruction of the gastric outlet by a gallstone, which can enter the duodenum through a fistula. While the average age of individuals with Bouveret syndrome is 74 years, our patient was 42 years of age at the time of operation, significantly younger than the average patient afflicted with this condition. In the treatment of our patient's condition, the operation conducted entailed a partial duodenectomy, gastrojejunostomy, cholecystectomy, common bile duct exploration, extraction of bile duct stones, and insertion of a t-tube in the bile duct. The patient was found to be in healthy condition upon check-up six months after the operation. The outcome of our case suggests that younger Bouveret patients can safely undergo multiple surgical procedures in the treatment of Bouveret syndrome. Our case also suggests that a cholecystectomy and the removal of the obstructing gallstone can both be carried out within one operation, although coupling these two procedures in one operation might be riskier for patients within the normal age range of Bouveret syndrome. We also suggest that fistula repair be carried out for younger Bouveret patients in particular and that the patient be subjected to a CT scan in the diagnosis of Bouveret syndrome when this condition is suspected.
