Eleven years of primary closure of common bile duct after choledochotomy for choledocholithiasis.

BACKGROUND: The choice of surgical technique to extract stones from the common bile duct (CBD) depends on local experience, anatomical characteristics and also on the size, location and number of stones. Most authors consider choledochotomy an alternative to failed transcystic exploration, although some use it exclusively. Although the CBD is traditionally closed with T-tube drainage after choledochotomy, its use is associated with 11.3-27.5 % morbidity. This study examined the efficacy of laparoscopic CBD exploration (LCBDE) with primary closure for the treatment of CBD stones using intraoperative cholangiography (IOC). METHODS: Retrospective study of 160 patients who underwent LCBDE with primary closure after choledochotomy between January 2001 and December 2012. RESULTS: The diagnosis of choledocholithiasis was definitively made in all cases by IOC. The overall complication rate was 15 % and the biliary complication rate was 7.5 %. Bile leakage was reported in 11 patients (6.8 %). In over half the cases (63.6 %), no further action was required and the leak closed spontaneously. Six patients were reoperated (3.75 %), two for bile peritonitis and four for haemoperitoneum. The success rate for stone clearance was 96.2 %. The mortality rate and CBD stricture rate were 0 %. CONCLUSION: Primary closure after choledochotomy to clear stones from the CBD is a safe technique that confers excellent results and allows one-stage treatment.

Recurrence of biliary disease following non-operative management in elderly patients.

INTRODUCTION: The purpose of this study was to determine the proportion of symptomatic recurrence following initial non-operative management of gallstone disease in the elderly and to test possible predictors. METHODS: This is a single institution retrospective chart review of patients 65 years and older with an initial hospital visit (V1) for symptomatic gallstone disease, over a 4-year period. Patients with initial "non-operative" management were defined as those without surgery at V1 and without elective surgery at visit 2 (V2). Baseline characteristics included age, sex, Charlson comorbidity index (CCI), diagnosis, and interventions (ERCP or cholecystostomy) at V1. Outcomes assessed over 1 year were as follows: recurrence (any ER/admission visit following V1), surgery, complications, and mortality. A survival analysis using a Cox proportional hazards model was performed to assess predictors of recurrence. RESULTS: There were 195 patients initially treated non-operatively at V1. Mean age was 78.3 ± 7.8 years, 45.6% were male, and the mean CCI was 2.1 ± 1.9. At V1, 54.4% had a diagnosis of biliary colic or cholecystitis, while 45.6% had a diagnosis of cholangitis, pancreatitis, or choledocholithiasis. 39.5% underwent ERCP or cholecystostomy. Excluding 10 patients who died at V1, 31.3% of patients had a recurrence over the study period. Among these, 43.5% had emergency surgery, 34.8% had complications, and 4.3% died. Median time to first recurrence was 2 months (range 6 days-4.8 months). Intervention at V1 was associated with a lower probability of recurrence (HR 0.3, CI [0.14-0.65]). CONCLUSION: One-third of elderly patients will develop a recurrence following non-operative management of symptomatic biliary disease. These recurrences are associated with significant rates of emergency surgery and morbidity. Percutaneous or endoscopic therapies may decrease the risk of recurrence.

Management of a Rare Challenging Case of Duodenal Ampullary Lipoma.

Duodenal lipoma is a very rare entity with limited case reports present in literature. But duodenal ampullary lipomas are even more rare in nature. Owing to the recent advances in endoscopy and modern imaging techniques, more cases are being diagnosed and treated. However, challenge lies in performing a less invasive and least morbid procedures to treat them surgically in such complex location of tumour. To study the diagnosis and treatment of duodenal ampullary lipoma in a young male patient and challenges faced during surgical management. A 15-year-old young boy presented to us with complaints of intermittent upper gastrointestinal bleed and jaundice since last 2 months. At admission, his serum haemoglobin was 3 g% for which he was transfused 3 units of packed blood cells for optimization. On further evaluation, CT scan abdomen revealed 71 × 49 mm large heterogeneous mass in D3 segment of duodenum causing duodeno-duodenal intussusception involving D1 and D2 segment along with ampullary region with mass being the lead point. There was compression of CBD with dilatation measuring 11 mm in diameter and mild IHBR dilatation. UGIE revealed narrowing at D1-D2 junction due to polypoidal lesion with overlying smooth mucosa with no active bleeding point identified. His blood parameters were normal except for low haemoglobin (before blood transfusion) and total serum bilirubin of 2.3 mg/dl.He was optimized for surgery and underwent exploratory laparotomy with duodenotomy at D2 with mass excision of 7 × 5 cm sessile polyp with base over ampulla followed by plastic repair of sphincter of Oddi (pancreas preserving procedure). He was started on oral liquids on POD 3 and was discharged on normal diet by POD 7 with an uneventful recovery. Result of histopathological report revealed, on gross cut section, the presence of mass of 7 × 5 × 3 cm size with smooth mucosa and fibrofatty tissue. On microscopic examination, diagnosis of submucosal lipomatous polyp was made. Our case report indicated duodenal ampullary lipoma is extremely rare entity. The symptoms are nonspecific and CT scan abdomen is the first investigation of choice for diagnosis. The treatment depends on the patient's condition as well as the size and position of the tumour. In our case report, the tumour base was exactly at the level of ampulla where we performed complex procedure of local excision of mass with sphincteroplasty avoiding major Whipple procedure for such benign condition. It provided rapid postoperative recovery to the patient.

Intraductal papillary mucinous neoplasm of the intrahepatic bile duct: a review of literature and a rare case report.

Background: Intraductal papillary neoplasm of the bile duct is a rare variant of bile duct tumors, which is characterized by papillary or villous growth inside the bile duct. Having papillary and mucinous features such as those found in pancreatic intraductal papillary mucinous neoplasm (IPMN) is extremely rare. We report a rare case of intraductal papillary mucinous neoplasm of the intrahepatic bile duct. Case report: A 65-year-old male Caucasian with multiple comorbidities presented to the emergency room with moderate constant pain at the right upper quadrant (RUQ) abdomen for the last several hours. On physical examination, he was found to have normal vital signs, with icteric sclera and pain on deep palpation at the RUQ region. His laboratory results were significant for jaundice, elevated liver function tests and creatinine, hyperglycemia, and leukocytosis. Multiple imaging studies revealed a 5 cm heterogeneous mass in the left hepatic lobe that demonstrated areas of internal enhancement, mild gall bladder wall edema, dilated gall bladder with mild sludge, and 9 mm common bile duct (CBD) dilatation without evidence of choledocholithiasis. He underwent a CT-guided biopsy of this mass, which revealed intrahepatic papillary mucinous neoplasm. This case was discussed at the hepatobiliary multidisciplinary conference, and the patient underwent an uneventful robotic left partial liver resection, cholecystectomy, and lymphadenectomy. Conclusion: IPMN of the biliary tract may represent a carcinogenesis pathway different from that of CBD carcinoma arising from flat dysplasia. Complete surgical resection should be performed whenever possible because of its significant risk of harboring invasive carcinoma.

Common bile duct injury following open conversion of laparoscopic cholecystectomy in 14-15 Weeks pregnancy: A rare case report.

Introduction: Common bile duct (CBD) injury is the most serious complication of Laparoscopic Cholecystectomy (LapC). Nonetheless, complications of LapC as a treatment for CBD injury are rare in pregnancy. There have been no published case reports regarding complications of CBD injury in gravida patients and their management. Case presentation: We reported a 32-year-old primiparous woman with CBD injury following open conversion of LapC in 14-15 weeks of pregnancy with enterocutaneous fistula complications. She presented with yellowish fluid leakage from an open wound in her abdomen, and had a history of gallbladder removal and corrective surgery due to bile leakage and intestinal adhesions. Tenderness and serous fluid were found in the area of the previous surgery scar. The laboratory examination showed that the patient was in anaemic condition; Fetal ultrasound examinations showed that the fetus' condition was within normal limits. The patient was given supportive and medical management with further MRCP plans as well as maternal-fetal close and regular monitoring. Clinical discussion: In addition to the history and physical examinations, biliary tract imaging holds a pivotal role in this case. LapC is a surgical technique recommended to treat symptomatic cholelithiasis in pregnancies. Despite being rare in pregnancy, prevention of CBD injury by recognizing the pearls and pitfalls of LapC should be done. Conclusion: Key points for successful treatment of this case are characterized by early recognition of CBD injury, fluid collection and infection control, nutritional balance, and multidisciplinary approaches of the Surgery Department and Obstetrics-Gynaecology Department.

Post-operative ascites of unknown origin after laparoscopic cholecystectomy: Case report.

Introduction and importance: Post Laparoscopic cholecystectomy ascites is a rare complication that might be due to biliary leak, lymph duct injuries, infections, peritoneal reaction bowel injuries, malignancies and etc. Case presentation: Here we have reported post-cholecystectomy ascites presented with hypovolemic shock in a women of unknown origin. Different possible etiologies have been ruled out for her but her intra-peritoneal secretions had been decreased about one week of hospitalization and was discharged without figuring out its etiology. Clinical discussion: Post-cholecystectomy ascites is a rare condition that could be caused by biliary leak, lymphatic leak, ovarian hyper stimulation syndrome, infections, peritoneal reactions and malignancies that all of them should be considered for these patients to manage their problem. Conclusion: The exact cause of ascites in the presented case was still unknown and the condition was controlled by administration of corticosteroids, octreotide, albumin, and insertion of the stents in biliary ducts. More investigation esp. on immunologic causes are needed.

Portal Cavernoma Cholangiopathy in Children: An Evaluation Using Magnetic Resonance Cholangiography and Endoscopic Ultrasound.

BACKGROUND: Portal cavernoma cholangiopathy (PCC) refers to abnormalities of the extra- and intrahepatic bile ducts in patients with portal cavernoma. The literature on PCC in children is very scarce. This study aimed at characterizing PCC in children with extrahepatic portal venous obstruction (EHPVO) using endoscopic ultrasound (EUS) and magnetic resonance cholangiography/portovenography (MRC/MRPV). METHODS: A total of 53 consecutive children diagnosed with EHPVO were prospectively evaluated for PCC using MRC/MRPV and EUS. Chandra classification was used for type of involvement and Llop classification for grading of severity. RESULTS: All 53 children (100%) had PCC changes on MRC/EUS, but none were symptomatic. Extrahepatic ducts (EHDs) and intrahepatic ducts were involved in majority (85%), and 58.5% had severe changes. Periductal thickening/irregularity (71%) was the commonest change in intrahepatic ducts, whereas irregular contour of the duct with scalloping (68%); common bile duct (CBD) angulation (62.3%) were the frequent changes in the EHDs. Increased CBD angulation predisposed to CBD strictures (P = 0.004). Both left and right branches of portal vein were replaced by collaterals in all children. Among the EUS biliary changes, para-pericholedochal, intrapancreatic, and intramural gall bladder collaterals had significant association with severity, with higher frequency of occurrence in children with the most severe Llop Grade. CONCLUSIONS: PCC develops early in the disease course of EHPVO, in children, but is asymptomatic despite severe changes. EUS biliary changes are more likely to be observed with increasing severity of PCC.

Type Va Duplication of the Common Bile Duct With Type IIIa Intrahepatic Bile Duct Anatomy: A Rare Combination of Dual Biliary Ductal Anomaly With Difficulty to Extract Common Bile Duct Stone.

Extrahepatic duplication of the common bile duct (CBD) is an extremely rare anatomic variation seen in the biliary tract. It represents failure of regression of the primitive duplicated biliary ductal system, resulting in five different subtypes of the duplicated CBD as described by Choi et al. To date, only few such cases have been reported in the literature. Associated variation in branching of intrahepatic bile ducts presenting as combined dual ductal anomaly is even rarer phenomena to be seen. We report a case of a 67-year-old man with chronic kidney disease and obstructive jaundice resulting from choledocholithiasis. Evaluation revealed type IIIa branching of intrahepatic bile ducts with type Va duplication of the CBD.

Paradoxical alteration of indocyanine green concentration in bile and the visibility of the intra-operative fluorescence cholangiography in pigs.

Background: A significant difference exists between the reported optimal timing of indocyanine green (ICG) injection during fluorescence cholangiography and ICG dissipation time from the serum. There are no reports on alterations in ICG concentration in biliary fluid over time. Herein, we measured the concentration of ICG and the fluorescence intensity ratio between the common bile duct (CBD) and liver, which was recognized as a parameter of the visibility of the CBD. Materials and methods: ICG (0.05 mg/kg) was injected intravenously into female pigs (n = 7). Afterwards, the fluorescence of the CBD and liver was detected at 30 min, 2 h, and 4 h. Biliary fluid was collected from cannulated CBD tubes. The fluorescence intensity was measured using captured images and calculated using the ImageJ image-processing program. ICG concentration was measured using spectrophotometry and compared using an analysis of variance test. Results: Biliary ICG concentrations at 30 min, 2 h, and 4 h were 92.07 ± 27.72 µg/mL, 37.14 ± 9.76 µg/mL (p < 0.05 vs. 30 min), and 13.91 ± 5.71 µg/mL (p < 0.05 vs. 30 min), respectively; p < 0.01. The CBD/liver fluorescence intensity ratios at 30 min, 2 h, and 4 h were 1.25 ± 0.72, 2.39 ± 1.28 (p < 0.05 vs. 30 min and 4 h), and 3.38 ± 1.73 (p < 0.05 vs. 30 min and 2 h), respectively. Conclusions: The ICG biliary concentration was highest at 30 min, whereas the CBD/liver fluorescence intensity ratio was highest at 4 h. Decreasing the fluorescence intensity of the liver may be an important approach for improving the visualization of the CBD during fluorescence cholangiography. Institutional protocol number: PE/EA/491-5/2020.

Development of a prognostic MRCP-score (DiStrict) for individuals with large-duct primary sclerosing cholangitis.

Background & Aims: Magnetic resonance cholangiopancreatography (MRCP) is used for the diagnosis and follow-up of individuals with primary sclerosing cholangitis (PSC). The aim of our study is to develop an MRCP-score based on cholangiographic findings previously associated with outcomes and assess its reproducibility and prognostic value in PSC. Methods: The score (DiStrict score) was developed based on the extent and severity of cholangiographic changes of intrahepatic and extrahepatic bile ducts (range 0-8) on 3D-MRCP. In this retrospective, multicentre study, three pairs of radiologists with different levels of expertise from three tertiary centres applied the score independently. MRCP examinations of 220 consecutive individuals with PSC from a prospectively collected PSC-cohort, with median follow-up of 7.4 years, were reviewed. Inter-reader and intrareader agreements were assessed via intraclass correlation coefficient (ICC). After consensus, the prognostic value of the score was assessed using Cox-regression and outcome-free survival rates were assessed via Kaplan-Meier estimates. Harrell's C-statistic was calculated. Results: Forty patients developed outcomes (liver transplantation or liver-related death). Inter-reader agreement between experienced radiologists was good (ICC 0.82; 95% CI 0.74-0.87, and ICC 0.81; 95% CI 0.70-0.87, respectively) and better than the agreement for the pair of experienced/less-experienced radiologists (ICC 0.48; 95% CI 0.05-0.72). Agreement between radiologists from the three centres was good (ICC 0.76; 95% CI 0.57-0.89). Intrareader agreement was good to excellent (ICC 0.85-0.93). Harrell's C was 0.78. Patients with a DiStrict score of 5-8 had 8.2-fold higher risk (hazard ratio 8.2; 95% CI 2.97-22.65) of developing outcomes, and significantly worse survival (p <0.001), compared to those with a DiStrict score of 1-4. Conclusions: The novel DiStrict score is reproducible and strongly associated with outcomes, indicating its prognostic value for individuals with PSC in clinical practice. Impact and implications: The diagnosis of primary sclerosing cholangitis (PSC) is based on magnetic resonance cholangiopancreatography (MRCP). However, the role of MRCP in the prognostication of PSC is still unclear. We developed a novel, simple, and reproducible risk-score, based on MRCP findings, that showed a strong association with prognosis in individuals with PSC (DiStrict score). This score can be easily used in clinical practice and thus has the potential to be useful in clinical trials and in patient counselling and management.

Gallstone Disease in Cirrhosis-Pathogenesis and Management.

Gallstones are more common in patients with cirrhosis of the liver, and the incidence increases with severity of liver disease. Pigment stones are the most frequent type of gallstones (GSs) in cirrhotics, and majority remain asymptomatic. Hepatitis C virus infection and nonalcoholic fatty liver disease are the underlying etiologies of liver diseases that most often associated with GSs. Multiple altered mechanisms in cirrhosis such as chronic hemolysis due to hypersplenism, reduced bile acid synthesis and transport, decreased cholesterol secretion, decreased apolipoprotein A-I and A-II secretion, gallbladder hypo-motility, autonomic dysfunction, and portal hypertension collectively lead to increased risk of lithogenesis. Asymptomatic GSs should be followed up closely and offered laparoscopic cholecystectomy once symptomatic in Child-Pugh class A and B patients. The model for the end-stage liver disease score is the best predictor of the outcome after cholecystectomy. In patients of Child-Pugh class C, conservative or minimally invasive approaches should be used to treat complications of GSs.

Long-Term Outcomes of Endoscopic Management of Patients with Symptomatic Portal Cavernoma Cholangiopathy with No Shuntable Veins for Surgery or Failed Surgery.

Background and Aim: Shunt surgery is the definitive treatment for symptomatic patients with portal cavernoma cholangiopathy (PCC), but few patients are non-surgical candidates or fail to improve even after surgery. This study aims to analyze the long-term outcomes of endoscopic therapy in these patients. Methods: Retrospective review of a prospectively maintained database of all patients with symptomatic PCC managed with endoscopic retrograde cholangiography (ERC) followed by stent placement. Outcomes studied included number of biliary interventions, complications, resolution of stricture, development of decompensation and mortality. Results: Thirty-five patients (68.6% males, median age = 35 years) with a median follow-up duration of 46 months (12-112) were included in the analysis. Presentation was only jaundice in 51.4% cases while one-third (37.1%) of the patients presented with cholangitis. Patients underwent a total of 363 endoscopic sessions with a median of 9 procedures (3-29) per patient. Hemobilia was the most common complication of the procedure (6.06%). Ten (28.5%) patients required frequent stent exchanges. Patients who required frequent stent exchanges had higher number of cholangitis episodes and hospitalization. Secondary biliary cirrhosis developed in 4 (11.4%) patients and 2 (5.7%) patients had mortality. Of the 5 (14.3%) patients who were given a stent free trial, 3 patients required restenting due to redevelopment of symptoms. Conclusion: Patients with PCC without shuntable veins for surgery or those who failed to improve after surgery can be managed long-term with repeated endoscopic intervention with a slightly increased risk of non-fatal hemobilia.

Misdiagnosis of sphincter of Oddi disorder treated as familial Mediterranean fever for ten years: A case report.

INTRODUCTION: Sphincter of Oddi dysfunction is a rare disease caused by sphincter of Oddi functional or mechanical abnormality. Misdiagnosis of familial Mediterranean fever is very high due to overlapping symptoms with many diseases. Our case is the first case report in the medical literature which describes the misdiagnosis of Sphincter of Oddi dysfunction as familial Mediterranean fever. CASE PRESENTATION: A 46-year-old woman presented with recurrent episodes of abdominal pain and arthralgia. The patient had familial Mediterranean fever for ten years which was diagnosed clinically without performing genetic tests. Analysis of the mutation in the MEFV gene was performed and was negative. Thereby, the diagnosis of familial Mediterranean fever was eliminated and colchisine was discontinued. Afterward, laboratory and radiological tests were performed, and the diagnosis of sphincter of Oddi disfunction was confirmed. The patient underwent biliary sphincterotomy and take sulpiride daily. DISCUSSION: The most common diseases were misdiagnosed with familial Mediterranean fever are appendicitis, acute rheumatic fever, gastrointestinal diseases and inflammatory arthritis. Endoscopic retrograde cholangiopancreatography with Manometry of the Sphincter of Oddi is the gold-standard test. CONCLUSION: Sphincter of Oddi dysfunction may interfere with many other disorders and should be considered as a differential diagnosis for any recurrent abdominal pain. Misdiagnosis of familial Mediterranean fever is common in endemic countries due to the reliance on clinical symptoms without analysis of the mutations in the MEFV genes particularly, before 1997.
