Objective:To study the safety and feasibility of anatomic left hemihepatectomy via cranial-dorsal approach in the treatment of left hepatolithiasis.Methods:Clinical data of 47 patients with left intrahepatic bile duct stones who underwent cranial-dorsal approach laparoscopic anatomic left hemihepatectomy in Hunan People's Hospital from October 2016 to June 2022 were retrospectively analyzed, including 15 males and 32 females, aged (56.45±1.37) years old. The operative time, intraoperative blood loss, postoperative liver function and complications were analyzed. Patients were followed up by telephone and outpatient review.Results:All 47 patients successfully underwent laparoscopic surgery without conversion. The median operative time was 260 (range, 160-440) min. The median intraoperative blood loss was 100 ml (range, 20-400 ml). The total bilirubin, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were 15.7 (11.7, 21.9) μmol/L, 126.6 (91.7, 168.5) U/L, and 151.1 (98.0, 212.4) U/L on postoperative day (POD) 1, respectively, and decreased to 12.6 (9.6, 16.2) μmol/L, 97.9 (60.7, 156.9) U/L, 54.2 (40.0, 104.1) U/L on POD 3, respectively. The median postoperative hospital stay was 7 (range, 4-24) d. Postoperative abdominal effusion and infection occurred in one patient, and the complication rate was 2.1% (1/47). Postoperative CT review found residual stones in common bile duct in one patient [2.1% (1/47)]. No stone recurrence or death occurred during postoperative follow-up.Conclusion:Anatomic left hemihepatectomy via cranial-dorsal approach is a safe and feasible surgery for the treatment of left hepatolithiasis.

Comparison of percutaneous transhepatic choledochoscopic lithotripsy and traditional open hepatectomy in the treatment of regional hepatolithiasis with biliary cirrhosis / 中国医师杂志

Objective:To compare the therapeutic effects of percutaneous transhepatic choledochoscopic lithotripsy (PTCSL) and traditional open hepatectomy (OH) on regional hepatolithiasis with biliary cirrhosis.Methods:From January 2020 to August 2022, 110 cases of regional hepatolithiasis complicated with biliary cirrhosis treated in the hepatology department of Hunan Provincial People′s Hospital were retrospectively collected. According to the surgical methods of treating hepatolithiasis, the patients were divided into minimally invasive group and laparotomy group. The minimally invasive group received PTCSL, and the laparotomy group received OH. The clinical data of the two groups were compared and analyzed, and the postoperative exhaust time, gastrointestinal function recovery time, operation time and intraoperative bleeding volume were observed. The levels of alanine aminotransferase (ALT), γ-glutamyltransferase(GGT) and aspartate aminotransferase (AST) before and after operation were compared between the two groups. The incidence of complications and stone removal rate of the two groups were recorded.Results:The postoperative exhaust time (11.12±2.09)h, gastrointestinal function recovery time (25.76±4.28)h, operation time (108.51±16.19)h, intraoperative blood loss (20.16±3.59)ml and postoperative exhaust time (29.35±4.83)h and gastrointestinal function recovery time in the minimally invasive group were less than those in the laparotomy group (36.91±6.35)h, operation time (116.27±21.54)h and intraoperative blood loss (38.03±6.22)ml (all P<0.05). The levels of ALT (77.82±16.25)U/L, GGT (248.16±24.83)U/L and AST (65.42±16.82)U/L in the minimally invasive group after operation were lower than those in the laparotomy group [ALT (102.37±25.64)U/L, GGT (345.45±32.60)U/L and AST (96.30±22.17)U/L] (all P<0.05). The incidence of postoperative complications was 7.27%(4/55) in the minimally invasive group and that in the laparotomy group was 29.09%(16/55), with statistically significant difference ( P<0.05). The stone removal rate was 61.82%(34/55) in the minimally invasive group and 92.73%(51/55) in the laparotomy group, with statistically significant difference ( P<0.05). Conclusions:PTCSL and OH are effective in the treatment of regional hepatolithiasis complicated with biliary cirrhosis. The traditional OH has a high stone removal rate, and PTCSL has little influence on liver function, small complication rate and fast postoperative recovery.

Objective:To investigate the clinical efficacy of precise hepatectomy for the treatment of recurrent unilateral hepatolithiasis and prognostic factors.Methods:The retrospec-tive case-control study was conducted. The clinicopathological data of 166 patients with recurrent unilateral hepatolithiasis who were treated by precise hepatectomy in the First Affiliated Hospital of Anhui Medical University from January 2015 to January 2021 were collected. There were 51 males and 115 females, aged (58±12)years. Observation indicators: (1)diagnosis and classification; (2) surgical and intraoperative situations; (3) postoperative situations; (4) follow-up; (5) analysis of prognostic factors. Follow-up was conducted using the outpatient examination and telephone inter-view to detect final stone clearance or recurrence and survival of patients up to August 2021. Patients with T-tube were performed T-tube cholangiography or choledochoscopy to evaluate the final stone clearance rate at postoperative week 8. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers or percentages. Univariate and multi-variate analyses were conducted using the Logistic regression model. Results:(1) Diagnosis and classifica-tion: 166 patients were diagnosed as hepatolithiasis by preoperative imaging examination and intraoperative evaluation, including 134 cases with common bile duct stones. Of the 166 patients, 115 cases had stones located in the left lobe of liver and 51 cases had stones located in the right lobe of liver. There were 111 cases with bile pigment stones, 31 cases with cholesterol stones, 24 cases with mixed type of stones. There were 9 cases classified as Tsunoda type Ⅰ, 89 cases as Tsunoda type Ⅱ, 65 cases as Tsunoda type Ⅲ, 3 cases as Tsunoda type Ⅳ. There were 12 cases classified as type Ⅰ, 99 cases as type Ⅱ, 47 cases as type Ⅲ, 8 cases as type Ⅳ according to Japanese classification in 2001. All the 166 patients were classified as type Ⅰ based on Chinese classification. According to the classification of author team, 166 patients were classified as type Ⅱ. (2) Surgical and intra-operative situations: 119 of 166 patients had liver lobe or segment atrophy.

For biliary drainage methods of 166 patients, 120 patients received T-tube external drainage, 23 cases received choledochojejunostomy, 23 cases received choledochojejunostomy combined with T-tube external drainage. The original cholangiojejunal anastomotic stenosis was found and reconstructed in 10 patients. The operation time was (258±87)minutes and intraopera-tive blood transfusion rate was 16.87%(28/166) of 166 patients. All the 166 patients underwent fiber choledochoscopy, showing 77 cases with normal function of Oddi sphincter, 38 cases with disorder, 40 cases with dysfunction. There were 11 patients undergoing choledochojejunostomy who were not evaluate the function of Oddi sphincter. There were 21.69%(36/166)of patients with intra-hepatic biliary stricture. One hundred and forty-nine of 166 patients were conducted bile culture, showing the positive rate as 75.17%(112/149). There were 22 cases cultured multiple kinds of bacteria. The most common bacterium was Escherichia coli (43 cases), followed by Pseudomonas aeruginosa (12 cases), Klebsiella pneumoniae (9 cases), Klebsiella oxytoca (7 cases), Enterococcus faecium (7 cases). (3) Postoperative situations. The postoperative complication rate of 166 patients was 16.87%(28/166). In the 8 patients with serious complications of Clavien-Dindo grade Ⅲ, 6 cases were performed thoracocentesis or abdominocentesis for effusion, 1 case was stopped bleeding under gastroscopy for stress ulcerbleeding, 1 case was performed surgery for adhesive intestinal obstruction. Two patients with septic shock of Clavien-Dindo grade Ⅳ were converted to intensive care unit for treatment and discharged after recovery. There were 13 patients with biliary leakage, 10 patients with pulmonary infection, 6 cases with incision infection, which were improved after conservative treatments. There was no perioperative death. The instant stone clearance rate of 166 patients was 81.93%(136/166). The duration of postoperative hospital stay of 166 patients was (11±6)days. (4) Follow-up: 166 patients were followed up for (37±17)months. The final stone clearance rate and stone recurrence rate of 166 patients were 94.58%(157/166) and 16.87%(28/166), respectively. According to Terblanche classification of prognosis, there were 91, 36, 25, 14 cases of grade Ⅰ, Ⅱ, Ⅲ, Ⅳ in 166 patients, respectively. Five of the 166 patients underwent intrahepatic secondary malignancy in which 4 cases died. (5) Analysis of prognostic factors: results of univariate analysis showed that biliary culture, the number of previous surgeries, immediate stone clearance, final stone clearance were related factors affecting the prognosis of precise hepatectomy in patients with recurrent unilateral hepatolithiasis ( odds ratio=2.29, 7.48, 2.69, 4.52, 95% confidence interval as 1.09?4.85, 2.80?19.93, 1.16?6.25, 1.15?17.77, P<0.05).

RESUMEN Se presenta paciente de 28 años, bangladeshi, ingresado en el Cuban Hospital de Qatar por dolor abdominal, fiebre moderada e ictericia ligera, elevación de las enzimas hepáticas y pancreáticas, además de presentar patrón humoral de colestasis. La ecografía abdominal y la tomografía de abdomen con contraste endovenoso detectaron vesícula biliar distendida con pared gruesa, litiasis en las vías biliares extra e intrahepáticas con dilatación de las mismas y escasa cantidad de líquido y edema peri pancreático, concluyéndose como pancreatitis aguda secundaria a colecistitis litiásica. Se realizó una colangiopancreatografia retrógrada endoscópica, y se comprobaron estos hallazgos y estenosis del conducto hepático derecho asociado a no permeabilidad del conducto hepático izquierdo. El diagnóstico cambió a colangitis piógena oriental. Por esta vía se extrajeron los cálculos y se colocó stent. El paciente fue tratado complementariamente con antibióticos, piperacilina y tazobactam vía IV, egresado con evolución satisfactoria después de nueve días del ingreso. Actualmente se encuentra en seguimiento por equipo multidisciplinario para definir conducta quirúrgica definitiva.

ABSTRACT A 28-year-old Bangladeshi patient is presented, admitted to the Cuban Hospital in Qatar for:abdominal pain, moderate fever and mild jaundice, elevated liver and pancreatic enzymes, as well as a humoral pattern of cholestasis. Abdominal ultrasound and abdominal tomography with intravenous contrast detected a distended gallbladder with a thick wall, lithiasis in the extra and intrahapatic bile ducts with dilatation of the same and little amount of fluid and peri-pancreatic edema, concluding as acute pancreatitis secondary to lithiasic cholecystitis. An endoscopic retrograde cholangiopancreatography was performed, verifying these findings and stenosis of the right hepatic duct associated with non-patency of the left hepatic duct, the diagnosis changed to oriental pyogenic cholangitis. By this route, the stones were extracted and a stent was placed. The patient was treated with complementary antibiotics, piperazine and IV tazobactam, and was discharged with satisfactory evolution nine days after admission. He is now being followed by a multidisciplinary team to define definitive surgical conduct.

Clinical efficacy of perihilar surgical techniques for diffuse hepatolithiasis / 中华消化外科杂志

Objective:To investigate the clinical efficacy of perihilar surgical techniques for diffuse hepatolithiasis.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 122 patients with diffuse hepatolithiasis who were admitted to Hunan Provincial People's Hospital from January 2010 to December 2015 were collected. There were 39 males and 83 females, aged from 21 to 82 years, with a median age of 51 years. After perihilar hepatectomy, the first, second and third divisions of hepatic ducts were opened longitudinally. Strictures in the bile ducts were relieved by stricturoplasty and internal bile duct anastomosis, and stones were removed by multiple methods under direct vision. After resection of severe atrophic liver segment along the plane of hepatic atrophy or bile duct stricture, T-tube or hepaticojejunos-tomy was used for internal drainage. Observation indicators: (1) surgical situations; (2) stricture relief and stone removal. (3) Follow-up. Follow-up was conducted by Wechat, telephone interview or outpatient examination. Patients were followed up once every 3 months in the postoperative 1 year through liver function and abdominal B-ultrasound examination. Subsequently, liver function and abdominal B-ultrasound were reexamined once a year. Magnetic resonance cholangiopancreato-graphy and computed tomography were performed when cholangitis or stone recurrence was suspected to analyze stone recurrence and patient survival. The follow-up was up to July 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range). Count data were expressed as absolute numbers or percentages. Results:(1) Surgical situations: for the 122 patients, the operation time, hepatic portal occlusion time, volume of intraoperative blood loss, duration of postoperative hospital stay were (253±71)minutes, 15 minutes(range, 14?38 minutes), 200 mL(range, 100?1 100 mL), (12±5)days. Postoperative complications occurred to 40 of 122 patients. There were 9 cases of incision infection, 8 cases of bile leakage (5 cases of bile leakage at hepatic section, 3 cases of choledochojejunostomy leakage), 8 cases of septicemia, 7 cases of pleural effusion, 5 cases of abdominal abscess, 3 cases of liver failure, 1 case of biliary bleeding. Some patients had multiple complications. Among the 122 patients, 2 cases died after operation, including 1 case of postoperative liver failure and 1 case of disseminated intravascular coagulation caused by biliary-intestinal anastomotic leakage complicated with sepsis. Patients with bile leakage and abdominal abscess were improved after puncture and drainage under the guidance of B-ultrasound. Patients with cholangiojejunal anastomotic bleeding were embolized through the right hepatic artery. The other complications were improved after conservative treatment. (2) Stricture relief and stone removal: 85 of 88 patients with biliary stricture were relieved, with the stricture relief rate of 96.59%(85/88). Among the 122 patients, 103 cases had stones completely removed and 19 cases had residual stones. The immediate stone clearance rate was 84.43%(103/122). Of the 19 patients with residual stones, choledochoscopy was refused in 3 cases and choledochoscope lithotripsy was performed in 16 cases, of which 7 cases were removed and 9 cases were still residual stones. Of the 122 patients, 110 cases were finally removed stones, 12 cases were eventually residual stones, and the final stone clearance rate was 90.16%(110/122). (3) Follow-up: among the 122 patients, 120 cases including 110 cases with find stone removal and 10 cases with residual stones were followed up for (78±14)months. The 1-, 3, 5-year stone recurrence rates of 120 patients were 0.83%(1/120), 6.67%(8/120), 9.17%(11/120), respectively. The 1-, 3-, 5-year stone recurrence rates of 110 patients with final stone removal were 0, 5.45%(6/110), 5.45%(6/110), respectively. The number of cases with stone recurrence at postoperative 1-, 3- and 5-year of 10 patients with residual stones were 1, 2, 5 cases, respectively. Of 120 patients with follow-up, 1 case died of end-stage liver disease, and the other patients had good survival.Conclusion:Perihilar surgical techniques for diffuse hepatolithiasis is safe and effective.

Treatment outcome of hepatolithiasis: Nepalese experience

Background: Hepatolithiasis is a rare disease with high rate of treatment failure and recurrence. This study aims to review the burden, management and outcome from an endemic region.Methods: A retrospective review of database of patients with hepatolithiasis managed surgically from 2015 to 2019 was performed. Diagnosis was based on the clinical findings and radiological investigations. Demographic data, clinical presentation, extent of disease and type of surgical management were evaluated. The outcome measures included immediate stone clearance, postoperative complications and follow-up.Results: Hepatolithiasis was seen in nine (0.34%) out of 2,600 patients being evaluated for gallstone disease. Three patients were young, while the remaining six were in the middle-age group. The presenting symptoms were pain abdomen (78%) and jaundice (22%). Hepatolithiasis was located in the left, right and both ductal systems in 5, 1 and 3 patients respectively. Liver resection for unilateral disease was done in 3 patients: left hepatectomy (n=2) and left lateral segmentectomy (n=1). High bile duct exploration and bilio-enteric drainage was done in 5 patients. One patient required hepatolithotomy and T-tube drainage due to cholangitis. Complete stone clearance was achieved in 78%. Complications included surgical site infection and cholangitis in 2 patients. There was no operative mortality. Histopathology revealed recurrent pyogenic cholangitis. At median follow-up of 28 months, 7 patients are symptom-free.Conclusions: Hepatectomy is an effective treatment when disease is confined to the left lobe. Combined surgical procedure is an acceptable option for bilateral or right-sided hepatolithiasis.

Hepatolitiasis izquierda manejada con hepatectomía: Reporte de un caso

La hepatolitiasis es un desorden de las vías biliares caracterizado por la presencia de cálculos en los conductos biliares intrahepáticos. Existen varios factores de riesgo asociados a esta patología, pero su complicación más temida es el desarrollo de un colangiocarcinoma. En el Ecuador no hay literatura sobre el manejo de esta patología y su pronóstico postoperatorio. Se presenta el caso de un paciente masculino de 50 años de edad, con un cuadro de dolor abdominal en epigastrio, acompañado de hiporexia y náusea, sin hallazgos relevantes en el examen físico. Se encontraron pruebas de función hepática alteradas y marcadores tumorales elevados, además, los estudios radiológicos evidenciaron dilatación de la vía biliar intrahepática, con litos en su interior. Se decidió realizar una hepatectomía izquierda y, posteriormente, el estudio histopatológico evidenció cambios sugestivos de displasia en los conductos intrahepáticos. El paciente es dado de alta con una evolución dentro de los parámetros esperados y es remitido a seguimiento por Consulta Externa. En conclusión, la hepatolitiasis es una condición que al no ser tratada puede desarrollar un colangiocarcinoma, aumentando el riesgo del paciente

Hepatolithiasis is a bile duct disorder characterized by the presence of stones in the intrahepatic bile ducts1. There are several risk factors associated with this pathology, but its most feared complication is the development of cholangiocarcinoma2. In Ecuador there is not published literature regarding the management and prognosis of this pathology. A 50-year-old male patient with a picture of abdominal pain in the epigastrium, accompanied by hyporexia and nausea, without relevant findings on the physical exam. Altered liver function tests and raised tumor markers were found, in addition, radiological studies showed dilation of the intrahepatic bile duct, with bile stones inside. A left hepatectomy was performed, and subsequently the histopathological study demonstrated suggestive dysplasia changes in the intrahepatic ducts. Patient is discharged with a positive evolution and is referred to clinic for further follow up. To sum up, hepatolithiasis is a condition that should promptly be treated to avoid the development of a cholangiocarcinoma, which could put in risk the patient's life.

No blood transfusion was needed during the operations. The duration of hospital stay was 20.5 days (range, 14.0-29.0 days). There was no perioperative death. One patient had postoperative biliary leakage and abdominal infection, and was cured after conservative treatment. (2) Typical case analysis: the tenth patient, female, 60 years old, was diagnosed with complicated hepatolithiasis, and was prepared to undergo hepatolithotomy+ quadrate lobectomy and hilar cholangioplasty+ bilateral hepatojejunostomy. Preoperative CT images and intraoperative color Doppler ultrasound images of the patient were fused and matched on the sagittal section of the portal vein and the cross section of the right branch of portal vein, and stones and important vessels were marked on the images. After accurate positioning, a curette was used to remove the stones. Removal of biliary stones through hepatic parenchyma and peripheral dilated bile ducts was conducted at the site where stones obviously existed. After the stones were removed, the intrahepatic bile duct and hilar bile duct merged. The left end of the bile duct split was confirmed by real-time ultrasound. After location of portal vein was determined by ultrasound, vascular plastic surgery was perfomed to avoid stenosis. (3) Follow-up: 10 patients were followed up for 6-12 months, with a median follow-up time of 8 months. One of 10 patients was suspected residual stones at the right peripheral hepatic anterior lobe by postoperative angiography at 2 months after surgery, and was not removed stones by choledochoscope. The patient had no recurrent symptoms after T-tube removal. The other 9 patients had no residual stones.@*Conclusion@#RVS applied in complicated hepatolithiasis is helpful for the precise intraoperative diagnosis, and the surgical treatment can be safe and effective.

Minimally invasive integrated traditional Chinese and Western medicine therapy for hepatolithiasis based on the SELECT concept / 临床肝胆病杂志

Hepatolithiasis is difficult to treat in clinical practice and has high recurrence rate and incidence rate of complications, improper diagnosis and treatment can easily lead to hepatic insufficiency, and thus it has become one of the difficult problems to be solved in clinical practice. With the improvement of medical equipment and the wide application of various minimally invasive endoscopic techniques, most patients with hepatolithiasis can receive effective treatment. Traditional Chinese medicine therapy can prevent the recurrence of calculi and promote patients’ recovery during the perioperative period. Based on the SELECT (Spyglass, ERCP, Laparoscopy, EUS, Choledochoscopy, Traditional Chinese Medicine) concept, minimally invasive treatment with a combination of various endoscopies should be selected according to the type and clinical features of hepatolithiasis and integrated traditional Chinese and Western medicine therapy should be given in the perioperative period to realize the minimally invasive, diversified, and individualized integrated traditional Chinese and Western medicine therapy for hepatolithiasis.

Treatment strategies of complicated extrahepatic bileduct stones / 中华消化外科杂志

Complicated extrahepatic bile duct stone is defined as not easy to achieve the treatment standard of total stone clearance, stricture removal, unobstructed drainage and recurrence preventing in a single operation or combined with other liver diseases, which include hepatic hilar bile duct stones incarceration, distal bile duct stone incarceration, Mirizzi syndrome, residual cystic duct stones, recurrent extrahepatic bile duct stones, and combined with portal hypertension or intrahepatic bile duct stones. Through comprehensive and meticulous preoperative evaluation, we can clarify the cause of extrahepatic bile duct stones, the location of stones and bile duct stenosis, the variability of bile duct, the anatomy of the hepatoduodenal ligament, the condition of liver function and biliary tract infection, and make the proper surgery plan. During the surgery, we apply the perihilar surgical techniques, pancreatic hilar plate reduction techniques, Oddi sphincter incision and shaping, and choledochoscopic lithotripsy and lithotomy comprehensively to achieve the goal of reducing residual stone rate and recurrence rate. It is important that reasonably select endoscopic retrograde cholangiopancreatography indications, correctly hold indications of bilioenteric anastomosis, and prevent iatrogenic injury of extrahepatic bile ducts on the premise of clearing stones.
