Etiology-Based Decision-Making Protocol for Pediatric Cholelithiasis

OBJECTIVES

We reviewed hospital records of pediatric cholelithiasis to develop an etiology-based decision-making protocol.

METHODS

This retrospective study was conducted on consecutive pediatric cholelithiasis patients from July, 2014 to June, 2019 in a tertiary care center. Pediatric cholelithiasis was classified according to etiology, and the outcome of medical/surgical treatment was noted.

RESULTS

Data of 354 pediatric patients were analyzed. Commonest (56.2%) etiology was idiopathic; followed by ceftriaxone pseudo-lithiasis (26.8%). Pigment stones were associated with the highest rate of complications. Non-hemolytic stones had a lower complication rate and a high rate of resolution with medical therapy.

CONCLUSIONS

Hemolytic and symptomatic stones warrant an early cholecystectomy, whereas asymptomatic idiopathic stones, ceftriaxone stones, and TPN-induced stones are candidates for medical therapy under close observation.

Frail geriatric patients with acute calculous cholecystitis: Operative versus nonoperative management?

INTRODUCTION

Nonoperative management of acute calculous cholecystitis (ACC) in the frail geriatric population is underexplored. The aim of our study was to examine long-term outcomes of frail geriatric patients with ACC treated with cholecystectomy compared with initial nonoperative management.

METHODS

We conducted a 2017 analysis of the Nationwide Readmissions Database and included frail geriatric (≥65 years) patients with ACC. Frailty was assessed using the five-factor modified frailty index. Patients were stratified into those undergoing cholecystectomy at index admission (operative management [OP]) versus those managed with nonoperative intervention (nonoperative management [NOP]). The NOP group was further subdivided into those who received antibiotics only and those who received percutaneous drainage. Primary outcomes were procedure-related complications in the OP group and 6-month failure of NOP (readmission with cholecystitis). Secondary outcomes were mortality and overall hospital length of stay.

RESULTS

A total of 53,412 geriatric patients with ACC were identified, 51.0% of whom were frail: 16,791 (61.6%) in OP group and 10,472 (38.4%) in NOP group (3,256 had percutaneous drainage, 7,216 received antibiotics only). Patients were comparable in age (76 ± 7 vs. 77 ± 8 years; p = 0.082) and modified frailty index (0.47 vs. 0.48; p = 0.132). Procedure-related complications in the OP group were 9.3%, and 6-month failure of NOP was 18.9%. Median time to failure of NOP management was 36 days (range, 12-78 days). Mortality was higher in the frail NOP group (5.2 vs. 3.2%; p < 0.001). The NOP group had more days of hospitalization (8 [4-15] vs. 5 [3-10]; p < 0.001). Both receiving antibiotics only (odds ratio, 1.6 [1.3-2.0]; p < 0.001) and receiving percutaneous drainage (odds ratio, 1.9 [1.7-2.2]; p < 0.001) were independently associated with increased mortality.

CONCLUSION

One in five patients failed NOP and subsequently had complicated hospital stays. Nonoperative management of frail elderly ACC patients may be associated with significant morbidity and mortality.

[National survey on the treatment of cholelitiasis in Spain during the initial period of the COVID-19 pandemic]

Introduction

The extraordinary impact of COVID-19 pandemic on Spanish hospitals has led to a redistribution of resources for the treatment of these patients, with a decreased capacity of care for other common diseases. The aim of the present study is to analyse how this situation has affected the treatment of cholecystitis and cholelythiasis.

Methods

It is a descriptive national study after online voluntary distribution of a specific questionnaire with Google Drive™ to members of the Spanish Association of Surgeons (AEC).

Results

We received 153 answers (one per hospital). Elective cholecystectomies have been cancelled in 96.7% of centres. Conservative treatment for acute cholecystitis has been selected in 90% (previously 18%), and if operated, 95% have been performed laparoscopically. Globally, only 49% perform preoperative diagnostic tests for SARS-CoV-2, and 58.5% recognize there have been cases confirmed postoperatively after other surgeries, with worse surgical outcomes in 54%.

Conclusions

This survey shows that most of the Spanish centers are following the surgical societies suggestions during the pandemic. However, some data requires to be taken into account for the next phase of the pandemic.

Beta-Thalassemia Intermedia: A Single Thalassemia Center Experience from Northeastern Iraq

OBJECTIVE

To determine the molecular characterization and disease-associated complications of beta-thalassemia intermedia (β-TI) patients in Sulaymaniyah province, northeastern Iraq.

METHODS

A total of 159 β-TI) patients in Sulaymaniyah province, northeastern Iraq. β-TI) patients in Sulaymaniyah province, northeastern Iraq.

RESULTS

Nineteen different β-globin gene mutations arranged in 37 various genotypes were determined. The most frequent were IVS-II-I (G>A) (47.2%), followed by IVS-I-6 (T>C) (23.3%) and IVS-I-110 (G>A) (5%). Among disease-related morbidities documented, bone disease amounted to 53% (facial deformity and osteoporosis), followed by endocrinopathies 17.6% (growth retardation and subclinical hypothyroidism), cholelithiasis 13.8%, pulmonary hypertension 11.3%, and abnormal liver function test 7.5%, whereas venous thrombosis, extramedullary hemopoiesis, and leg ulcer were less frequently observed. Age ≥ 35 and female sex were risk factors for cholelithiasis, while age was an independent risk for hypothyroidism and female sex was associated with increased risk for osteoporosis. Mean serum ferritin of ≥1000 μg/L was associated with an increased risk of osteoporosis, whereas chelation therapy was protective for a multitude of other complications. Transfusion, on the other hand, increased the risk of osteoporosis, yet it was protective for cholelithiasis and hypothyroidism. Moreover, splenectomy was protective for cholelithiasis, although it was an independent risk for hypothyroidism. Finally, hydroxyurea was associated with an increased risk of osteoporosis, while it was protective for cholelithiasis. Discussion and Conclusion. β +-thalassemia mutation had contributed to 41.25 of families with a less severe β-thalassemia phenotype in the northeastern part of Iraq, justifying the need to investigate the contribution of genetic modifiers in ameliorating disease severity. In addition, the substantial number of β-TI patients developed disease-related morbidities, which necessitates the need for more appropriate clinical management with earlier intervention.β-TI) patients in Sulaymaniyah province, northeastern Iraq. μg/L was associated with an increased risk of osteoporosis, whereas chelation therapy was protective for a multitude of other complications.

Recent advances in understanding and managing cholesterol gallstones

The high prevalence of cholesterol gallstones, the availability of new information about pathogenesis, and the relevant health costs due to the management of cholelithiasis in both children and adults contribute to a growing interest in this disease. From an epidemiologic point of view, the risk of gallstones has been associated with higher risk of incident ischemic heart disease, total mortality, and disease-specific mortality (including cancer) independently from the presence of traditional risk factors such as body weight, lifestyle, diabetes, and dyslipidemia. This evidence points to the existence of complex pathogenic pathways linking the occurrence of gallstones to altered systemic homeostasis involving multiple organs and dynamics. In fact, the formation of gallstones is secondary to local factors strictly dependent on the gallbladder (that is, impaired smooth muscle function, wall inflammation, and intraluminal mucin accumulation) and bile (that is, supersaturation in cholesterol and precipitation of solid crystals) but also to "extra-gallbladder" features such as gene polymorphism, epigenetic factors, expression and activity of nuclear receptors, hormonal factors (in particular, insulin resistance), multi-level alterations in cholesterol metabolism, altered intestinal motility, and variations in gut microbiota. Of note, the majority of these factors are potentially manageable. Thus, cholelithiasis appears as the expression of systemic unbalances that, besides the classic therapeutic approaches to patients with clinical evidence of symptomatic disease or complications (surgery and, in a small subgroup of subjects, oral litholysis with bile acids), could be managed with tools oriented to primary prevention (changes in diet and lifestyle and pharmacologic prevention in subgroups at high risk), and there could be relevant implications in reducing both prevalence and health costs.

Oriental cholangiohepatitis (recurrent pyogenic cholangitis): a case series from the Netherlands and brief review of the literature

Oriental cholangiohepatitis is a condition occurring in the Asian population, characterised by recurrent bacterial cholangitis and presence of calculi within the intrahepatic bile ducts, biliary strictures and an increased risk for cholangiocarcinoma. It is an uncommon disease in the West that may not always be considered. The therapeutic approach is multidisciplinary and highly individual, and includes antibiotic therapy, endoscopic and percutaneous biliary drainage with stone removal and dilation of strictures, and in selected cases surgical resection of affected liver segments. We report our experience with five relatively young adult patients largely originating from China, who presented with pyogenic cholangitis and were considered to suffer from oriental cholangiohepatitis. To our knowledge this is the first report of this condition in the Netherlands. Physicians treating patients with pyogenic cholangitis should be aware of this disease and consider the diagnosis in all Asian immigrants with biliary tract disease.

Usefulness of single-operator cholangioscopy-guided laser lithotripsy in patients with Mirizzi syndrome and cystic duct stones: experience at a tertiary care center

BACKGROUND AND AIMS

ERCP is an established technique for the management of bile duct stones. Large bile duct stones (>1.2 cm) require additional techniques such as mechanical lithotripsy and balloon sphincteroplasty for ductal clearance. The literature on endoscopic management of cystic duct stones (CDSs) and Mirizzi syndrome (MS) is limited. We report our experience with cholangioscopy-assisted extraction of CDSs and MS in patients in whom conventional endoscopic and surgical techniques failed.

METHODS

Between August 2011 and August 2014, 50 patients (15 males) diagnosed with MS (n = 40) and CDSs (n = 10) were recruited for the study. MRCP was the preferred diagnostic modality to outline the biliary anatomy. ERCP was performed by using an Olympus TJF 160/180 duodenoscope (Olympus, Tokyo, Japan). Cholangioscopy was performed by using the Spyglass system (Boston Scientific, Marlborough, Mass). Holmium laser lithotripsy (LL) was performed when conventional stone extraction techniques failed.

RESULTS

Cholangioscopy-guided LL was required in 34 of 50 patients (68%) with MS and CDSs. Stone extractions using conventional endoscopy techniques were successful in 8 patients and with surgery in another 8 patients, and these patients were excluded from the final statistical analysis. The mean stone size for MS was 21 mm (range 15-41 mm), and the CDS size was 8 mm (range 6-12 mm). Single-session ductal clearance could be achieved in 32 patients (94%). Adverse events were mild and included fever (2 patients), transient abdominal pain (2 patients), and self-limited pancreatitis (2 patients).

CONCLUSIONS

Cholangioscopy-guided LL is a useful technique for extraction of CDSs and in MS with high single-session success rates. It is also a rescue technique in patients in whom surgical stone extraction failed.

Transient Worsening of Photosensitivity due to Cholelithiasis in a Variegate Porphyria Patient

Variegate porphyria (VP) is an autosomal dominant disease caused by mutations of the protoporphyrinogen oxidase (PPOX) gene. This porphyria has unique characteristics which can induce acute neurovisceral attacks and cutaneous lesions that may occur separately or together. We herin report a 58-years-old VP patient complicated with cholelithiasis. A sequencing analysis indicated a novel c.40G>C mutation (p.G14R) in the PPOX gene. His cutaneous photosensitivity had been worsening for 3 years before the emergence of cholecystitis and it then gradually improved after cholecystectomy and ursodeoxycholic acid treatment with a slight decline in the porphyrin levels in his blood, urine and stool. In VP patients, a worsening of photosensitivity can thus be induced due to complications associated with some other disease, thereby affecting their porphyrin-heme biosynthesis.

Hepatolithiasis and intrahepatic cholangiocarcinoma: A review

Although the incidence of hepatolithiasis is decreasing as the pattern of gallstone disease changes in Asia, the prevalence of hepatolithiasis is persistently high, especially in Far Eastern countries. Hepatolithiasis is an established risk factor for cholangiocarcinoma (CCA), and chronic proliferative inflammation may be involved in biliary carcinogenesis and in inducing the upregulation of cell-proliferating factors. With the use of advanced imaging modalities, there has been much improvement in the management of hepatolithiasis and the diagnosis of hepatolithiasis-associated CCA (HL-CCA). However, there are many problems in managing the strictures in hepatolithiasis and differentiating them from infiltrating types of CCA. Surgical resection is recommended in cases of single lobe hepatolithiasis with atrophy, uncontrolled stricture, symptom duration of more than 10 years, and long history of biliary-enteric anastomosis. Even after resection, patients should be followed with caution for development of HL-CCA, because HL-CCA is an independent prognostic factor for survival. It is not yet clear whether hepatic resection can reduce the occurrence of subsequent HL-CCA. Furthermore, there are no consistent findings regarding prediction of subsequent HL-CCA in patients with hepatolithiasis. In the management of hepatolithiasis, important factors are the reduction of recurrence of cholangitis and suspicion of unrecognized HL-CCA.

Liraglutide-related cholelithiasis

Liraglutide is a glucagon-like peptide-1 analog and recently started to be using as an incretin-based treatment for diabetes mellitus. Liraglutide causes some adverse affects including nausea, vomiting, acute nasopharyngitis and acute pancreatitis. However, development of liraglutide-dependent cholelithiasis has not been reported in the literature. A 75-year-old female patient had been diagnosed with type 2 diabetes mellitus for 10 years and she has been treated by liraglutide for 6 months. The patient was admitted to the emergency service due to sudden onset of abdominal pain. After laboratory and imaging studies, she was diagnosed with acute cholecystitis and cholelithiasis. And then patient's oral intake was stopped, intravenous fluid and ceftriaxone 2 g/day were started. Furthermore, liraglutide treatment discontinued and ursodeoxycholic acid (UDCA) was started to treat cholelithiasis. During follow-up, abdominal pain completely relieved. Hepatobiliary ultrasonography in sixth month follow-up showed entirely regression of cholelithiasis. Any liraglutide-related cholelithiasis case has not been reported in the literature previously. Therefore, our case is the first case. Especially, elderly diabetic patients who are started to liraglutide treatment should be monitored closely for the formation of cholelithiasis. UDCA treatment would be an alternative prior to surgical treatment for liraglutide-related cholelithiasis.

Successful treatment of complex cholangiolithiasis following orthotopic liver transplantation with interventional radiology

Bile duct stones are a serious and the third most common complication of the biliary system that can occur following liver transplantation. The incidence rate of bile duct stones after liver transplantation is 1.8%-18%. The management of biliary stones is usually performed with endoscopic techniques; however, the technique may prove to be challenging in the treatment of the intrahepatic bile duct stones. We herein report a case of a 40-year-old man with rare, complex bile duct stones that were successfully eliminated with percutaneous interventional techniques. The complex bile duct stones were defined as a large number of bile stones filling the intra- and extrahepatic bile tracts, resulting in a cast formation within the biliary tree. Common complications such as hemobilia and acute pancreatitis were not present during the perioperative period. The follow-up period was 20 mo long. During the postoperative period, the patient maintained normal temperature, and normal total bilirubin and direct bilirubin levels. The patient is now living a high quality life. This case report highlights the safety and efficacy of the percutaneous interventional approach in the removal of complex bile duct stones following liver transplantation.

Endoscopic papillary large balloon dilation for removal of bile duct stones

AIM: To investigate the efficacy and outcomes of endoscopic papillary large balloon dilation (EPLBD) for bile duct stones in a multicenter prospective study.

METHODS: Lithotomy by EPLBD was conducted in 124 patients with bile duct stones ≥ 13 mm in size or with three or more bile duct stones ≥ 10 mm. After endoscopic sphincterotomy, the papilla was dilated using balloons 12-20 mm in diameter fitting the bile duct diameter.

RESULTS: The success rate of first-time lithotomy was 86.3% (107/124) and the final lithotomy success rate was 100% (124/124). Lithotripsy was needed in 10 of the 124 (13.6%) patients. Adverse events due to the treatment procedure occurred in 6 (4.8%) patients, all of which were mild. Performing large balloon dilation after endoscopic sphincterotomy in patients with large stones or multiple stones in the bile duct is considered to ensure the safety of treatment and to reduce the need for lithotripsy.

CONCLUSION: It is suggested that treatment by EPLBD for large bile duct stones may be safe and useful.

Cholesterol cholelithiasis in pregnant women: pathogenesis, prevention and treatment

Epidemiological and clinical studies have found that gallstone prevalence is twice as high in women as in men at all ages in every population studied. Hormonal changes occurring during pregnancy put women at higher risk. The incidence rates of biliary sludge (a precursor to gallstones) and gallstones are up to 30 and 12%, respectively, during pregnancy and postpartum, and 1-3% of pregnant women undergo cholecystectomy due to clinical symptoms or complications within the first year postpartum. Increased estrogen levels during pregnancy induce significant metabolic changes in the hepatobiliary system, including the formation of cholesterol-supersaturated bile and sluggish gallbladder motility, two factors enhancing cholelithogenesis. The therapeutic approaches are conservative during pregnancy because of the controversial frequency of biliary disorders. In the majority of pregnant women, biliary sludge and gallstones tend to dissolve spontaneously after parturition. In some situations, however, the conditions persist and require costly therapeutic interventions. When necessary, invasive procedures such as laparoscopic cholecystectomy are relatively well tolerated, preferably during the second trimester of pregnancy or postpartum. Although laparoscopic operation is recommended for its safety, the use of drugs such as ursodeoxycholic acid (UDCA) and the novel lipid-lowering compound, ezetimibe would also be considered. In this paper, we systematically review the incidence and natural history of pregnancy-related biliary sludge and gallstone formation and carefully discuss the molecular mechanisms underlying the lithogenic effect of estrogen on gallstone formation during pregnancy. We also summarize recent progress in the necessary strategies recommended for the prevention and the treatment of gallstones in pregnant women.

Endoscopic papillary balloon dilation: Revival of the old technique

Radiologists first described the removal of bile duct stones using balloon dilation in the early 1980s. Recently, there has been renewed interest in endoscopic balloon dilation with a small balloon to avoid the complications of endoscopic sphincterotomy (EST) in young patients undergoing laparoscopic cholecystectomy. However, there is a disparity in using endoscopic balloon papillary dilation (EPBD) between the East and the West, depending on the origin of the studies. In the early 2000s, EST followed by endoscopic balloon dilation with a large balloon was introduced to treat large or difficult biliary stones. Endoscopic balloon dilation with a large balloon has generally been recognized as an effective and safe method, unlike EPBD. However, fatal complications have occurred in patients with endoscopic papillary large balloon dilation (EPLBD). The safety of endoscopic balloon dilation is still a debatable issue. Moreover, guidelines of indications and techniques have not been established in performing endoscopic balloon dilation with a small balloon or a large balloon. In this article, we discuss the issue of conventional and large balloon endoscopic dilation. We also suggest the indications and optimal techniques of EPBD and EPLBD.

[Comparative evaluation of various methods of conservative therapy of early stage of cholelithiasis]

THE AIM OF INVESTIGATION: To explore the possibilities of use of conservative therapy in the early stage of cholelithiasis.

MATERIALS AND METHODS

In the treatment of patients with early stage of gallstone disease in 103 patients was used mineral water Uvinskaya, in 96--Ursosan and in 118--Ursosan combined with mineral water Uvinskaya.

RESULTS

The comparative evaluation of different variants of therapy showed that combined use of Ursosan and mineral water Uvinsky was the most effective to eliminate the clinical symptoms of the disease and reduce the lithogenic properties of bile.

Endoscopic retrograde cholangiopancreatography for stone burden in the bile and pancreatic ducts

Stones in biliary and pancreatic ducts are entities that plague hundreds of thousands of patients worldwide every year. Symptoms can be mild (pain) to life threatening (cholangitis, severe acute pancreatitis). In the last few decades, management of these stones has transitioned from exclusively surgical to now predominantly endoscopic techniques. This article reviews the evolution of endoscopic techniques used in the management of stones in the common bile duct and pancreatic duct.

[10 years of cholelithiasis classification (Central Scientific Research Institute of Gastroenterology): highlights of scientific and practical applications]

Clinical classification of cholelithiasisis presented, which includes 4 stages: stage without calculi, stage of formed gallstones, chronic calculous cholecystitis and complications. Sonographic description of main versions of biliary sludge, its causes and therapy efficacy are also given.

[Factors affecting contractile function of the gall blader in patients with cholelithiasis]

In article the data on interrelation between gallbladder contractility and a level of hormones of a thyroid gland (threeiodethyronine, thyroxine, thyrotropin hormone (TTH) and antibodies to thyreoperoxidase (AT to TPO)) in plasma of blood at 470 healthy persons and 540 patients with gallstone disease are submitted. The contractility function of a gallbladder on ultrasonic at persons with gallstone disease is authentic less, than at healthy persons. Dysfunction of a thyroid gland is found out in women with gallstone disease: increase TTH and AT to TPO. Among men hormonal shifts are not revealed. Contact chemical litholysis with methyl tert butyl ether of cholesterol stones in gallbladder except for their dissolution, improves its contractility activity.

[Innovations in the diagnosis and treatment of cholelithiasis]

AIM

To determine the density of densitometric gallstones and biliary sludge in order to clarify the possibility of lithotherapy in patients with gallstone disease (GSD).

MATERIALS AND METHODS

70 patients were carried out a comprehensive clinical examination with determination of densitometric density of gallstones and/or biliary sludge by means of computer tomography (CT), ultrasound of the abdomen, biochemical blood analysis. Assigned to the complex lithotherapy (Ursofalk and Kholit) in standard dosages, the results were evaluated in a year.

RESULT

It was found that the density of bile in patients with GSD was ranging from +4 to +10 HU, sludge - +17,5 HU, gall stones - over +20 HU. The main factor of the exoediency of conservative therapy of GSD is to determine the density of gallstone by CT, which should not exceed +54 HU (+29,6 +/- 3,4 HU). Visualization of stones on CT is much higher (30%) than in Rg (10%), and its density is observed at more than +75,0 HU. Sludge particle less than 2.0 mm, but having a density more than +20,0 HU, should be viewed as a gallstone. Kholit, a herbal medicine, improves functional and structural indicators of biliary tract, digestive processes of cavity, and may be recommended as a monotherapy in stage I of GSD, as well as a component of combination therapy of cholelithiasis.

[Current principles of cholelithiasis prophylaxis in the practice of district physician]

The key task of the district physician is staged diagnostic search and clinical detection of functional disorders--conduction of laboratory tests and device investigations (in cholelithiasis patients--ultramicroscopic investigation of bile, x-ray methods, ultrasonography) to initiate prophylactic-therapeutic measures (medico-social, pharmacological and therapeutic-dietary).

Single-operator cholangioscopy-guided laser lithotripsy in patients with difficult biliary and pancreatic ductal stones (with videos)

BACKGROUND

Scant data exist on the utility of the holmium:yttrium-aluminum-garnet laser for the treatment of biliary or pancreatic duct stones.

OBJECTIVE

To evaluate the efficacy and safety of fiberoptic probe and catheter system-guided holmium laser lithotripsy of difficult biliary and pancreatic duct stones.

DESIGN

Prospective study.

SETTING

Tertiary-care referral center.

PATIENTS

This study involved 64 patients who underwent holmium laser stone fragmentation.

INTERVENTION

A total of 64 patients (60 bile duct stones, 4 pancreatic duct stones) underwent endoscopic retrograde stone fragmentation with a holmium laser and a fiberoptic probe and catheter system. The inclusion criterion for bile duct stones was stones not amenable to retrieval by mechanical lithotripsy and/or balloon sphincteroplasty or standard techniques. Pancreatic duct stones included in this study were not amenable to removal by stone retrieval basket or balloon.

MAIN OUTCOME MEASUREMENTS

Rates of ductal clearance and procedural complications.

RESULTS

All 64 patients had successful fragmentation of biliary and pancreatic duct stones with the holmium laser. Fifty of 60 patients (83.3%) had complete biliary duct clearance after a single session; 10 patients required an additional session. All pancreatic duct stones were fragmented in a single session. Mean duration of ERCP sessions was 45.9 minutes (range 30-90 minutes). Complications were mild and were encountered in 13.5% of patients; fever (n = 3), transient abdominal pain (n = 4), and biliary stricture (n = 1).

LIMITATIONS

No comparative treatment group.

CONCLUSION

The fiberoptic probe and catheter system facilitates transpapillary access for holmium laser fragmentation of difficult biliary and pancreatic duct stones. The technique is safe and highly effective for single-setting duct clearance. Complications are minimal and transient.

[The application of sinusoidal modulated currents for the treatment of biliary sludge in an outpatient clinic]

The objective of the present study was to evaluate therapeutic effects of sinusoidal modulated currents (SMC) applied for the treatment of patients at different stages of biliary sludge (BS) under conditions of an outpatient clinic. Biliary sludge is currently considered to be a precursor of cholelithiasis known to be a leading pathology of the digestive system responsible for the high surgery rate. It was shown that the introduction of the technique based on sinusoidal modulated currents into the clinical practice of an outpatient clinic increases the efficacy of management of the patients presenting with stage 1 and 2 biliary sludge and showing neither well-apparent clinical symptoms nor signs of metabolic disorders that imply the necessity of more thorough examination and combined application of sinusoidal modulated currents and mediacmental therapy.

[Frequency and causes for hospitalization of children with cholelithiasis - own observations]

THE AIM

of this study was to assess the incidence and the cause of hospitalization of children with cholecystolithiasis.

MATERIAL AND METHODS

A retrospective analysis was carried out using medical data of children and adolescents treated in the Department of Pediatrics, Gastroenterology, and Pediatric Allergology of Bialystok Medical University. The analysis included causes of hospitalization, its course and accompanying illnesses. During the 4 years of analysis, 47 children (17 boys, 30 girls), aged from 7 months to 18 years, with the diagnosis of cholecystolithiasis were treated. The comprised 1.18% of children hospitalized with gastrointestinal disorders.

RESULTS

Cholecystolithiasis without complications was diagnosed in 29 children (61.7%), with cholecystitis in 13 (27.7%), choledocholithiasis was diagnosed in 5 children (10.6%). In 11 children (23.4%) the complication presented in form of acute pancreatitis. In 23 children (48.9%) factors predisposing to chorocholelithiasis were identified. In 20, the following were considered to be a possible significant factor: in 7 children there was a positive family history (14.9%), in 6 children (12.8%) - it was obesity, in 3 children (6.4%) lipid metabolic errors: prematurity and parenteral feeding in 2 children (4.3%) and spherocytosis in 2 children (4.3%). Apart from the above, cholelithiasis was diagnosed in two children with hypothyreosis and in two with Down's Syndrome. In treatment of 20 children (42.6%) antibiotics were prescribed and in 4 children (8.5%) endoscopic sphincterotomy was performed. 25 children (53.2%) were referred for laparoscopic cholecystectomy. In 16 children (34.0%), treatment with ursodeoxycholic acid was recommended.

CONCLUSIONS

Cholecystolithiasis is a rare cause of hospitalization in pediatric departments. However, it occurs in even the youngest children. It usually runs without complications, but there is a certain risk of serious complications. In the differential diagnosis of abdominal pain, cholelithiasis should be taken into account, even in the youngest children. Special consideration should be given to the premature, with low birth weight and extremely low birth weight.

Can a small endoscopic sphincterotomy plus a large-balloon dilation reduce the use of mechanical lithotripsy in patients with large bile duct stones?

BACKGROUND

Endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (EST) is technically difficult in the patients with large extrahepaic bile duct stones. Small endoscopic sphincterotomy combined with large-balloon dilation (ESLBD) currently seems to be a promising alternative for patients with difficult bile duct stones that cannot be extracted by EST. This study compared the therapeutic benefits and complication rates of ESLBD with those of EST alone.

METHODS

This study investigated 149 patients treated for stones (≥10 mm) or multiple stones in the extrahepatic bile duct. The ESLBD group (n = 72) was compared with the conventional EST group (n = 77). Mechanical lithotripsy was performed when the stone could not be removed using a Dormia basket.

RESULTS

The two groups did not differ significantly in terms of mean bile duct diameter, common bile duct angulation, and presence of periampullary diverticulum. The ESLBD group compared with the EST-alone group had similar outcomes in terms of overall successful stone removal but showed significant differences in complete stone removal during the first session (87.5 vs. 74.0%; P = 0.036) and the use of mechanical lithotripsy for large bile duct stones (≥15 mm) (17.9 vs. 45.8%; P = 0.026). For the patients with a periampullary diverticulum, ESLBD and EST showed similar results only for efficacy and complications.

CONCLUSIONS

The ESLBD technique may be a safe, effective alternative to conventional EST for endoscopic removal of large common bile duct stones, and it can reduce the use of mechanical lithotripsy compared with EST alone.

Antegrade papillary balloon dilation for extrahepatic bile duct stone clearance: lessons learned from treating 300 patients

PURPOSE

To report the authors' experience with percutaneous papillary balloon dilation for extrahepatic bile duct stone clearance to the duodenum in 300 patients.

MATERIALS AND METHODS

During a 16-year period, 300 patients with extrahepatic bile duct stones who underwent papillary balloon dilation were retrospectively evaluated. Two hundred eighty-six patients with retained extrahepatic bile duct stones were treated through a postoperative drain placed during cholecystectomy; 245 patients were treated through a T-tube route and 41 through a transcystic approach. In the remaining 14 patients, the procedure was performed through a newly created percutaneous transhepatic route. Success rates, technical features, reasons for failure, and complications were evaluated.

RESULTS

Biliary duct stone removal after papillary dilation was successful in 288 patients (96%). In 244 patients, the procedure was successfully completed on the first attempt. Forty-three patients needed two sessions, and in one patient it took three sessions. Stone diameters ranged from 4 mm to 18 mm (mean, 8 mm). Two hundred fourteen patients had four or fewer stones (mean, 2.3), and 86 patients had more than four (mean, 8.8; range, 5-25). Two patients required surgical intervention after loss of transcystic drainage, with subsequent development of peritonitis. During the follow-up period (mean, 26.6 months), no clinical or laboratory abnormalities were observed.

CONCLUSIONS

Percutaneous antegrade papillary balloon dilation and stone clearance is a safe and effective tool in removing common bile duct stones. Some technical issues should be considered to achieve complete stone removal while minimizing the incidence of complications.

[Pathology of biliary tract IN elderly patients with the system approach. Principles of therapy]

The biliary tract pathology gains the increasing distribution.So cholelitiasis in different camps is registered from 7.8 to 38%. In Russia the given indicator from 3 to 12%. Special importance cholelitiasis and chronic cholecystitis without cholelitiasis get at persons of the advanced age, connected as with morfofunkcional'nymi changes in an organism of senior citizens, and with a wrong way of life. All it demands the differentiated approach to treatment of this group of patients and includes change of a way of life, a dietotherapy, farmako- and physiotherapeutic treatment.

[Efficacy of balneotherapy in cholelithiasis]

AIM

To assess therapeutic efficacy of mineral water Uvinskaya at a prestone stage of cholelithiasis.

MATERIAL AND METHODS

A total of 135 cholelithiasis patients entered the trial. Of them 57 patients had a prestone stage and 78--stone stage of the disease. The stages were verified by clinical data, findings of dynamic hepatobiliscintigraphy, biochemical bile tests, anatomoemission spectroscopy with induction-bound plasma.

RESULTS

57 patients at prestone stage of cholelithiasis received balneotherapy with mineral water Uvinskaya. The treatment relieved pain syndrome, dyspeptic symptoms, enhanced absorption-excretion function of the liver, prolonged the time of maximal gall-bladder filling, shortened radiopharmaceutical half-life in the gall-bladder, raised the level of trace elements (magnesium, iron, potassium) in the bile, improved gall-bladder contraction, lithogenic bile characteristics.

CONCLUSION

Mineral water Uvinskaya has a positive effect in a physical-chemical stage of cholelithiasis.

[Therapeutic tactics in cholelithiasis in children]

Biliary tract diseases in children in recent years increasingly attracted the attention of not only physicians and surgeons, but this problem is becoming increasingly important in pediatric practice. Thus, gallstone disease in childhood is becoming a serious medical and social problem because of its chronic relapsing course, the development of severe complications, reduced quality of life and social adaptation of children. A particular difficulty is to select treatment tactics at cholelithiasis in childhood. The aim of this study was to demonstrate on the basis of own experience observing children with cholelithiasis, advantages and disadvantages of both surgical and conservative treatment of cholelithiasis in children, suggest alternative approaches for different periods of childhood.

[Treatment of patients with cholelithiasis and concomitant gastritis using sodium-calcium sulfate mineral water]

Choledocholithiasis (CDL) is known to be associated with gastric problems, such as disturbances of secretory function of the stomach. A frequent occurrence in this pathological condition is chronic gastritis with atrophy of gastric mucosa. It was shown that consumption of Uvinskaya mineral water during the period preceding calculi formation has beneficial therapeutic effect not only on the gallbladder function but also on both the morphological structure of the stomach and the secretory function of its mucous membrane.

[Transfistular approach for the treatment of retained biliary stones]

INTRODUCTION

Residual stones are those persisting in the biliary duct after a surgical intervention. They are found in approximately 2% of cases after a simple cholecistectomy and in 4% to 15% after an exploration of the common duct.

MATERIAL AND METHODS

Between January 2009 and June 2008, 81 patients were treated because of residual stones. Age, sex, number of stones, days in the hospital, laboratory, complications and diagnosis were analyzed.

RESULTS

Forty-eight patients were male and 33 female. The mean age was 42.5 years. Mean stay at hospital was 1.3 days. The mean number of procedures was 1.19. Fifty-two patients came from another institution and 28 belonged to our institution. The total of complications was 6.5%.

CONCLUSIONS

The percutaneous treatment for the residual stones is the goal standard in patients with "T" tube drainage and elevated risk for surgery. The advantage of this procedure is that it is economic, effective and with low risks for the patient. For the treatment of this disease, the collaboration of surgeons, endoscopists, and interventional radiologists is needed.

Therapeutic approach and prevention in recurrent acute biliary pancreatitis

OBJECTIVES

Acute biliary pancreatitis (ABP) is caused by alteration of the papillary patency. The normal transpapillar flux and the cleaning of the common biliary duct (CBD) may prevent potentially avoidable recurrent pancreatitis.

METHODS

In the period September 1997/December 2008 we have treated 224 ABP (34 severe, 190 mild/moderate): 162 (72,4%) with the first attack, 62 (27.6%) with recurrent ABP (second or further attack). The patients with recurrent pancreatitis had not undergone, in the previous hospital stay elsewhere, the evaluation and, if necessary, the treatment of the papillary obstacle and/or CBD stones, sludge, etc. In our hospital all patients had undergone the treatment of ABR The treatment was completed with cholecystectomy. All the patients, after the discharge, were introduced in a follow-up program (clinical and ultrasonographic (US) control after 180 days and 1 year).

RESULTS

In the follow-up of recurrent pancreatitis we have controlled 35 patients (56%-27 lost). The results of the follow-up showed, beside the absence of recurrent acute episodes, the stable normalization of laboratory cholestasis tests and US control. The same controls in 78 patients (48.1%) with a first attack of acute pancreatitis resulted normal in absence of a new acute episode.

CONCLUSIONS

Recurrent ABP have been caused by persistent papillary obstacle. Therefore we confirm therapeutic validity of the instrumental control (US/MRCP) and the possible treatment of papillary or biliary lithiasic obstacle for the prevention of recurrent ABP?

Choledocholithiasis: endotherapy versus surgery

When multiple treatment options are available, debate invariably persists regarding the optimal option. Confusion and controversy must then be resolved based on scientific evidence, but one needs to be practical because options depend on the available expertise. We aimed to evaluate the efficacy of endotherapy vis-à-vis surgery in patients with choledocholithiasis. The records of 349 patients with stone disease from February 2005 to January 2010 were analyzed. A total of 349 patients were analyzed: 279 patients with gallstones alone, 56 with choledocholithiasis, 3 with stones with stricture, 5 with common bile duct (CBD) and pancreatic duct (PD) stones, and 6 with combined choledocholithiasis and hepatolithiasis. In the 56 patients with choledocholithiasis alone, preoperative endoscopic retrograde cholangio pancreatography (ERCP) and endotherapy were followed by cholecystectomy within 48 hours. Endotherapy was successful in 15 patients, whereas surgery was required in the remaining 41 patients. Surgery is an efficacious option and can be carried out safely with acceptable morbidity and no mortality, even in difficult situations.

[Contact laser lithotripsy--an effective minimally traumatic method of treatment of cholelithiasis with calculi of the kidney, ureter and urinary bladder]

An experience with using contact laser lithotripsy is presented in treatment of such actual disease as cholelithiasis. This kind of modern minimally traumatic lithotripsy used in 73 patients has shown it to be effective independent of localization of the calculi: both in the urinary bladder and the kidney and ureter.

development of quality and consequences of medical care evaluation test at chronic calculouse cholecystitis by the expert--gastroenterologist. Defined defects, that statistically significantly determined negative outcomes, had fixed distribution within groups by frequency of these defects. Analysis resulted in calculation of the cumulative information value score of each case separately for diagnosis and treatment processes with assessment of probabilistic limits by binary logistic regression method with determination of limits of appropriate and inadequate medical care provision to chronic calculouse cholecystitis patients provide the algorithm for gastroenterologist.

Cholangiopancreatoscopy: a comprehensive review

Cholangiopancreatoscopy (CP) is a well-established modality for the direct visualization of intrahepatic biliary, extrahepatic biliary, and pancreatic ductal systems. The use of CP in the treatment of difficult biliary stones has become paramount when standard endoscopic retrograde cholangiopancreatography is ineffective. This article describes the available cholangioscopic devices and technical and clinical applications of cholangiopancreatoscopy. The efficacy and limitations of CP, as well as published comparative studies, are briefly reviewed.

Endosonography in the management of biliopancreatic disorders

Over the past two decades, endoscopic endosonography (EUS) has evolved into an indispensible diagnostic and therapeutic utility in the diagnosis and treatment of patients with pancreatobiliary disease. In this article, we summarise its current potential and provide an update of the latest literature.

Management of intrahepatic biliary lithiasis after pancreatic cancer surgery

Intrahepatic biliary lithiasis is fairly rare in western countries. In the case described here, liver stones had developed as a late consequence of biliary derivative surgery, which is well known to lead to this complication. However, this case is unusual because people who have undergone radical surgery for cancer of the head of the pancreas seldom survive long enough for liver stones to develop. Treatment for this 65-year-old woman, previously submitted to duodeno-cephalopancreatectomy, involved percutaneous balloon bilioplasty, with several passages in order to open the anastomosis. We then positioned two inner-outer biliary drains, through which repeated lavages were done. Finally, the patient underwent laser lithotripsy of the intrahepatic calculi and the fragments were cleared using a Dormia basket. Repeated cholangiographic monitoring showed progressively fewer stones, until the intrahepatic biliary tree was finally completely clear 120 days after the initial diagnosis. At the last follow-up, the patient was healthy, with normal blood values, considering her overall condition.

[Functional recovery of Oddi's sphincter after balloon dilatation of the papilla of Vater. An experimental study in rabbits]

INTRODUCTION

Balloon dilatation of the papilla of Vater is used to treat biliary lithiasis. The results and complications rate of this technique are excellent. Published data indicate that this procedure does not significantly alter the physiology of the sphincter of Oddi and that normal function is maintained. Papillary balloon dilatation would therefore provide an advantage over other techniques in which sphincteric function is abolished. The objective of this study was to evaluate the functional status of the sphincter of Oddi after balloon dilatation of the papilla of Vater.

MATERIAL AND METHODS

Twenty-four New Zealand albino rabbits were used. All animals underwent laparotomy and duodenotomy with balloon dilatation of the papilla of Vater. Manometric study of the biliary tract and of the sphincter of Oddi was also performed before, shortly after, and 21 days after dilatation. Biliary and sphincter of Oddi pressures and phasic activity of the sphincter (frequency, amplitude and duration of waves) were used as measuring variables for each of the stages of the experiment.

RESULTS

Papillary balloon dilatation immediately provoked substantial sphincter relaxation. Comparison of the values of basal biliary and sphincter of Oddi pressures with those found 21 days after dilatation showed no statistically significant differences. No significant differences were found when the variables related to phasic activity of the sphincter (frequency, amplitude and duration) were compared between the distinct phases of the experiment.

CONCLUSIONS

The results of the present study suggest complete recovery of sphincter function 21 days after balloon dilatation.
