ABSTRACT

Objective:To investigate the clinical characteristics and pathogenic mutations of propionic acidemia.Methods:Clinical data of two patients with propionic acidemia admitted to the Obstetrics and Gynecology Hospital of Nanjing Medical University from May 2017 to June 2018 were collected. Genomic DNA was extracted from the peripheral blood of the patients and their parents. Inherited disease panel based on Ion Torrent semiconductor sequencing technology was performed to detect gene mutations, and those with suspected pathogenic mutations were verified by Sanger sequencing. Descriptive statistical analysis was used for data analysis.Results:Case 1 was suspected of sepsis and admitted to the Obstetrics and Gynecology Hospital of Nanjing Medical University due to "drowsiness and milk rejection" on the second day after birth. Tandem mass spectrometry suggested the level of propionyl carnitine and its ratios to acetylcarnitine and free carnitine were increased. Urine gas chromatography-mass spectrometry showed elevated 3-hydroxypropionic acid and methylcitric acid. Genetic analysis revealed that the infant carried c.331C>T (p.R111X)/c.1228C>T (p.R410W) compound heterozygous mutations in the PCCB gene. The infant was diagnosed with propionic acidemia and treated with a special diet with an L-Carnitine supplement but died of sudden coma and vomiting without precipitating factors at three months of age. Case 2 presented with sudden vomiting, drowsiness, and anergia on the admission at five-months old. Tandem mass spectrometry showed increased propionyl carnitine level and its ratios. Compound heterozygous mutations of c.146delG (p.G49EfsX16)/c.1253C>T (p.A418V) in the PCCB gene were identified in the patient, of which c.146delG (p.G49EfsX16) was a de novo mutation and was evaluated as a pathogenic mutation. The patient was on a special diet with an L-Carnitine supplement, but with disobedience. Followed up to the age of three years and eight months, the child was severely underdeveloped. Conclusions:Neonates with clinically suspected sepsis may have propionic acidemia, and tandem mass spectrometry and genetic testing should be performed as soon as possible to confirm or rule out the diagnosis. Further investigations on the pathogenesis and function of the new mutation are still needed.

ABSTRACT

Objective:To study the indications and clinical efficacy of video assisted small incision in treatment of infected pancreatic necrosis.Methods:A retrospective study was conducted on 27 patients with infected pancreatic necrosis treated by video assisted small incision at the Department of Pancreatic and Splenic Surgery, Hunan Provincial People's Hospital, from January 2018 to December 2019. The surgical approach, operation time, intraoperative blood loss, postoperative hospital stay and complications were analysed. Postoperative follow-up was carried out at outpatients’ clinic, and the patient's time to full recovery and long-term complications were studied.Results:The 27 patients successfully underwent the operations. There were 22 males and 5 females, aged (50.6±6.2) years. The treatment results were analyzed according to the different surgical approaches: the retroperitoneal approach group ( n=4); the omental sac approach group (n=14); the intercostal space approach group ( n=2); and the combined approach group ( n=7). The operation time was (85.3±31.6)min. The intraoperative blood loss was 65.0(45.2, 121.4)ml. The postoperative hospital stay was 23.0(12.5, 36.1)days. The incidence of complications (Clavien-Dindo grade Ⅲ and above) was 14.8%(4/27). There were 2 patients in this study who were admitted to the intensive care unit due to postoperative hemorrhage: 1 patient responded well to conservative treatment and the remaining patient required interventional treatment. Another patient because of poor results, underwent debridement by laparotomy 2 weeks after the operation. There was 1 patient who developed grade C pancreatic fistula which was cured by surgical treatment 6 months later. On follow-up, 2 patients developed colonic fistula 2 weeks after surgery and 2 patients gastric fistula 1 week and 3 weeks after surgery. These patients responded to conservative treatment. Conclusion:With proper case selection, video assisted small incision could safely and effectively be used to treat infected pancreatic necrosis.

ABSTRACT

Objective:To study the value of metastatic positivety in lymph nodes group 8a in deciding on extended lymph node dissection in pancreaticoduodenectomy(PD) for pancreatic head cancer.Methods:A retrospective study on 165 patients with pancreatic head cancer treated with PD at the Department of Pancreas and Spleen Surgery, Hepatobiliary Hospital of Hunan Provincial People's Hospital between January 2014 to June 2019 was performed. There were 101 males and 64 females with ages ranging from 38 to 75 (median 57) years. Patients who underwent standard lymph node dissection were included in the standard group ( n=88), and extended lymph node dissection in the extended group ( n=77). These patients were further divided into 4 subgroup. Subgroup A (standard PD in patients with negative nodes in group 8a, n=61), Subgroup B (extended PD in patients with negative nodes in group 8a, n=47), Subgroup C (standard PD in patients with positive nodes in group 8a, n=27), and Subgroup D (extended PD in patients with positive nodes in group 8a, n=30). The operation time, intraoperative blood loss, postoperative survival rates, complications were compared among the groups and subgroups. Results:The operation time and intraoperative blood loss of the standard group were (456.8±30.4) min and (264.28±101.14) ml, respectively, which were significantly lower than the extended group of (507.1±45.7) min and (388.9±155.3) ml (all P<0.05). The incidence of postoperative complications in the extended group (31.2%, 24/77) was significantly higher than that in the standard group (14.8%, 13/88) ( P<0.05). When compared with subgroup B, the cumulative survival rate of patients in subgroup A was not significantly different ( P>0.05). However, the cumulative survival rate of patients in subgroup C was significantly lower than that in subgroup D ( P<0.05). The cumulative survival rate of subgroup A was also significantly better than that of subgroup C ( P<0.05). There was no significant difference in the cumulative survival rates between group B and group D ( P>0.05). Conclusions:PD with extended lymph node dissection improved the survival rates in patients with cancer of the head of the pancreas with positive lymph nodes in group 8a. For these patients, extended lymph node dissection is recommended. With negative lymph nodes in group 8a, standard lymph node dissection is recommended.

ABSTRACT

Objective To investigate the expression and clinicopathological significance of Bcl-2 and Bax genes in colorectal cancer (CRC) patients complicated with schistosomiasis. Methods The CRC patients receiving surgical treatment in the First Affiliated Hospital of Dali University from June 2016 to June 2020 were recruited as the study subjects, and 30 subjects were randomly sampled from the CRC patients complicated with schistosomiasis (CRC-S group) and 30 subjects were randomly sampled from the CRC patients without schistosomiasis (CRC group) using a random number table method. The cancer specimens were sampled from subjects in the CRC-S and CRC groups, and the peri-cancer specimens were sampled from subjects in the CRC group. The Bcl-2 and Bax expression was quantified in cancer and peri-cancer specimens using a real-time fluorescent quantitative PCR (qPCR) assay and immunohistochemistry at transcriptional and translational levels, and the cell apoptosis was detected in cancer specimens using HE staining. Results A total of 60 subjects were enrolled, including 30 cases in the CRC group and 30 cases in the CRC-S group. There were no significant differences between the two groups in terms of gender distribution (χ2 = 0.271, P > 0.05), mean age (t = -0.596, P > 0.05), tumor growth pattern (χ2 = 0.275, P > 0.05), tumor location (χ2 = 4.008, P > 0.05), tumor invasion depth (χ2 = 0.608, P > 0.05), degree of tumor differentiation (χ2 = 0.364, P > 0.05), or presence of vascular metastasis (χ2 = 1.111, P > 0.05), while significant differences were seen between the two groups in terms of histological type, presence of lymph node metastasis and TMN staging (χ2 = 5.963, 8.297 and 5.711, all P values < 0.05). qPCR assay and immunohistochemistry quantified significantly higher Bcl-2 and Bax expression in cancer specimens from the CRC and CRC-S groups than in the peri-cancer specimens from the CRC group at both translational and transcriptional levels (all P values < 0.05), and higher Bcl-2 and lower Bax expression were seen in the cancer specimens from the CSC-S group than that from the CRC group (all P values < 0.05). In addition, the cell apoptotic rate was significantly greater in the cancer specimens in the CRC group than in the CRC-S group (42.00% vs. 23.35%; χ2 = 41.500, P = 0.000). Conclusion Schistosomiasis may be involved in the development and progression of CRC through affecting Bcl-2 and Bax gene expression in the apoptosis signaling pathway.

ABSTRACT

To investigate the safety and feasibility of longitudinal transpancreatic U-sutures invaginated pancreatojejunostomy (Chen's pancreaticojejunostomy technique) in laparoscopic pancreaticoduodenectomy (LPD). Clinical data of 116 consecutive patients who underwent LPD using Chen's pancreaticojejunostomy technique in Hunan Provincial People's Hospital from May 2017 to December 2018 were retrospectively analyzed. Among these patients, 66 were males and 50 were females. The median age was 58 years old (32-84 yeas old). All 116 patients underwent pure laparoscopic whipple procedure with Child reconstruction method, using Chen's pancreaticojejunostomy technique. The intraoperative and postoperative data of patients were analyzed. All 116 patients underwent LPD successfully. The mean operative time was (260.3±33.5) minutes (200-620 minutes). The mean time of pancreaticojejunostomy was (18.2±7.6) minutes (14-35 minutes). The mean time of hepaticojejunostomy was (14.6±6.3) minutes (10-25 minutes). The mean time of gastrojejunostomy was (12.0±5.5) minutes (8-20 minutes). The mean estimated blood loss was (106.0±87.6) ml (20-800 ml). Postoperative complications were: 11.2%(13/116) of cases had postoperative pancreatic fistula (POPF), including 10.3% (12/116) of biochemical fistula and 0.9%(1/116) of grade B POPF, no grade C POPF occurred; 10.3%(12/116) had gastrojejunal anastomotic bleeding; 3.4%(4/116) had hepaticojejunal anastomotic fistula; 3.4%(4/116) had delayed gastric emptying; 4.3% (5/116) had localized abdominal infection; 12.1%(14/116) had pulmonary infection; postoperative mortality were 0(0/116) and 1.7%(2/116) within 30 days and 90 days, respectively. One patient died of massive abdominal bleeding secondary to Gastroduodenal artery pseudoaneurysm rupture, the other patient died of extensive tumor recurrence and metastasis after surgery. Chen's pancreaticojejunostomy technique is safe and feasible for LPD.It is an option especially for surgeons who have not completed the learning curve of LPD.

ABSTRACT

Objective:To establish a hypergravity loading model with a high-acceleration centrifugal loading device and to investigate the effects of different hypergravity loading and icariin on osteoblast adhesion and cytoskeleton.Methods:MC3T3-E1 cells were seeded in the dishes of cell culture at a density of 2×10 5/cm 2. And the experiment was divided into 6 groups: control group (without icariin and loading); simple administration group (only icariin); 10 G loading group (only loading); 10 G administration group (with icariin and loading); 40 G loading group (only loading); 40 G administration group (with icariin and loading). The experimental loading group was loaded with MC3T3-E1 cells using a high-acceleration centrifugal loader. And continuous loading for 3 d, 30 min per d. The control group and the simple administration group were exposed to normal gravity, and the remaining conditions were not different from the experimental group. Icariin was used at a concentration of 10 -7 mol/L in all administration groups, and the experiments were carried out according to the method of preventive administration. At the same time, the related molecular biological techniques such as alizarin red staining, alkaline phosphatase (ALP) activity measurement, CCK-8 cell proliferation experiment, cytoskeleton phalloidin staining, qPCR and Western Blot were used to detect the effects of icariin on osteoblasts adhesion protein integrin α5 and integrin β1 and cytoskeleton protein F-actin under hypergravity extreme mechanical environment. Results:All models were successfully prepared. The alizarin red staining: The icariin could significantly promote the formation of osteoblastic calcified nodules. And the 10 G loading could also promote the mineralization of osteoblasts and increase the number of mineralized nodules, while the mineralization and the number of mineralized nodules of osteoblasts are significantly reduced in 40 G loading. ALP activity test: The OD values of simple administration group, 10 G loading group and 40 G loading group were 0.246, 0.331 and 0.163, respectively. Compared with 0.207 in the control group, the differences were statistically significant ( P<0.05). The 10 G administration group and the 40 G administration group were 0.373 and 0.180, and the differences were statistically significant ( P<0.05). The results of CCK-8 proliferation experiments: The OD value of simple administration group were 0.650, which was statistically significant compared with 0.551 of control group ( P=0.031). The 10 G loading group and 40 G loading group were 1.193 and 0.245, and their differences with the control group were both statistically significant ( P<0.05). The OD value of 10G administration group and the 40 G administration group were 1.300 and 0.310, which were significantly different from the respective loading groups ( P<0.05). Phalloidin staining: 10 G loading significantly increased the number of cells, but the changes in cells morphology and skeleton were not obvious. 40 G loading significantly inhibited the increase of the number of cells, meanwhile, made the pseudopods of cells more shorter and even disappeared. 40 G loading made the seriously damage of the cytoskeleton and even cause the cells to death. Icariin had no effect on the cells morphology, but it did has a certain repair effect after the cells loading. The results of qPCR and Western Blot experiments all confirmed that the expressions of integrin α5, integrin β1 and F-actin were up-regulated after icariin treatment. 10 G loading could promote the expression of integrin α5, integrin β1 and F-actin, and 40 G loading significantly inhibited the expression of the mRNA and proteins. Conclusion:Both 10 G condition and icariin can promote the development, cell adhesion and the cytoskeleton's stability of osteoblasts, while 40 G has a significant inhibitory effect.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) complicated with pulmonary tuberculosis (PTB) is becoming more and more common. The coexistence of two diseases brings difficulty to the control of the disease. Smoking, biofuel exposure, vitamin D deficiency and diabetes may be common risk factors for both diseases. Complementary prevention and control strategies can be designed for the above risk factors. This article contains review with tuberculosis as a risk factor for COPD, COPD combined with tuberculosis, and the prevention strategies for both diseases.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is a common, preventable and treatable disease that is characterized by persistent respiratory symptoms and airflow limitation due to airway and/or alveolar abnormalities usually caused by significant exposure to noxious particles or gases. In addition to smoking COPD caused by cigarette smoke, the phenotype of non-smoking COPD accounts for at least 1/4. Non-smoking COPD accounts for a large proportion, especially in developing countries. Non-smoking COPD and smoking COPD should be paid equal attention. More in-depth study on the prognosis of non-smoking COPD is needed.

ABSTRACT

Laparoscopic anatomical hepatectomy of hepatic vein approach is a laparoscopic hepatectomy technique based on anatomical hepatectomy and guided by hepatic vein. It not only can completely remove the focus and retain the structural integrity of the remaining liver tissue, but also has the advantages of less trauma and rapid recovery by laparoscopy. When the transection plane is guided by complete exposure of hepatic vein, the ineffective liver tissue without inflow and outflow tract can be completely removed, the possibility of postoperative tumor recurrence and postoperative complications can be reduced, so as to improve the survival rate of patients. At present, it is of great clinical value and widely carried out. This article will review the development of anatomical hepatectomy of hepatic vein approach and the main points of laparoscopic anatomical hepatectomy of hepatic vein approach.

One case with intraperitoneal hemorrhage which represented as small amount of dark red liquid in the drainage tube of jejunum loop was cured after puncture-duct-douch treatment with noradrenaline sodium chloride solution. (3) Follow-up: Of the 121 patients, 113 (44 of type Ⅰ, 7 of type Ⅱ, 46 of type Ⅲ, 16 of type Ⅳ) were followed up for 3-58 months, with an average time of 34 months. During the follow-up, 13 patients (5 of type Ⅰ, 1 of type Ⅱ, 6 of type Ⅲ, 1 of type Ⅳ) had the recurrence of pain or pancreatitis, 55 patients (15 of type Ⅰ, 40 of type Ⅲ) with abdominal pain were improved significantly, and 45 patients (24 of type Ⅰ, 6 of type Ⅱ, 15 of type Ⅳ) did not have abdominal pain. Of the 37 patients (13 of type Ⅰ, 2 of type Ⅱ, 17 of type Ⅲ, 5 of type Ⅳ) with diabetes , 20 (6 of type Ⅰ, 2 of type Ⅱ, 12 of type Ⅲ) had blood glucose returned to normal and 17 (7 of type Ⅰ, 5 of type Ⅲ, 5 of type Ⅳ) needed controlling blood sugar with medicine. There were 5 patients (4 of type Ⅰ, 1 of type Ⅲ) diagnosed with diabetes and 3 patients (1 of type Ⅱ, 2 of type Ⅲ) with diarrhea postoperatively. Two patients of type Ⅲ chronic calcifying pancreatitis died, including 1 died of pancreatic cancer at 18 months after pancreaticoduodenectomy and 1 died of severe acute pancreatitis at 5 months after duodenum-preserving pancreatic head spoon-type resection.Conclusions:Chronic calcifying pancreatitis is a benign disease and should be treated to preserve functional tissues. Different surgical procedures should be adopted to treat different types of calcifying pancreatitis.

ABSTRACT

Objective:To investigate the clinical features, diagnosis, treatment and prognosis of primary testicular diffuse large B-cell lymphoma (PT-DLBCL).Methods:The clinical data of 2 patients with PT-DLBCL in the Second People's Hospital of Lianyungang treated in May 2013 and April 2018 was retrospectively analyzed. The clinical features, diagnosis, treatment and prognosis of PT-DLBCL were summarized with review of these 2 cases combining with other 42 cases reported in domestic literature.Results:Case 1, a 71 years old man, complained of bilateral scrotal enlargement with pain and discomfort for 2 months. Case 2, an 85 years old man, presented with left scrotal mass for 3 months. All 2 patients underwent orchiectomy. Both of the 2 patients were diagnosed as PT-DLBCL and non-germinal center B-cell (non-GCB) subtype and had Ann Arbor stage Ⅰ E after operation. Case 1 received only 2 cycles of CHOP (cyclophosphamide, epirubicin, vincristine, prednisone) due to lack of financial support. Case 2 refused chemotherapy and right testis irradiation because of advanced age. They were followed up for 71 months and 12 months, respectively. They were both alive without recurrence at last time of the follow-up. The median age of 44 patients (2 cases in this study and 42 cases reported in the domestic literature) was 64 years old (range 45-87 years old). The most common symptom was unilateral painless testicular swelling (left testis 17 cases and right testis 24 cases). Twenty-one patients were Ann Arbor stage Ⅰ, 6 patients were stage Ⅱ, 6 patients were stage Ⅲ, and 11 patients were stage Ⅳ. Thirty-one patients were non-GCB subtype. Twelve patients were international prognostic index (IPI) score ≥3. Serum lactate dehydrogenase (LDH) level was elevated in 13 patients. All patients underwent orchiectomy. CHOP/R-CHOP chemotherapy was given to 40 patients and prophylactic radiation to contralateral testis was given to 12 patients. Twenty-two patients received prophylactic intrathecal chemotherapy. After a median follow-up of 17 months (range 3-135 months), 14 patients died and the median overall survival time was 13 months (range 3-96 months). Conclusions:PT-DLBCL is rare. Its diagnosis mainly depends on pathology, with the majority of patients diagnosed in early Ann Arbor clinical stage and non-GCB subtype. The radical orchiectomy and R-CHOP chemotherapy is recommended due to local relapse and systemic dissemination. It is curable in the early stage while patients with advanced stage have a very poor prognosis. Prophylactic radiation to contralateral testis and intrathecal chemotherapy can decrease the risk of recurrence.

ABSTRACT

With the development of the 3rd-generation high-throughput sequencing technology and tissue engineering, recent studies show that many long-chain non-coding RNAs (LncRNAs) have played an important role in osteogenic differentiation of mesenchymal stem cells (MSCs). LncRNAs, which are involved in the regulation of mechanical regulation, further regulate bone-related cell functions and play a regulatory role at multiple levels, including transcription, post-transcriptional and epigenetic. LncRNAs may be involved in the osteogenic differentiation and bone remodeling of MSCs, the regulation of bone-related cell functions as a mechanical response molecule, as well as the pathological process of skeletal diseases.

ABSTRACT

Lung cancer is the leading cause of cancer-related deaths worldwide, and about 1.6 million people die of it each year. In China, the incidence and mortality of lung cancer rank the first, as evidenced by the fact that about 780 000 people suffering from lung cancer every year, and the 5-year survival rate is less than 20%. In addition, 85% of patients with lung cancer are non-small cell lung cancer (NSCLC), and 70% of lung cancer patients are found to have advanced cancer or tumor metastasis. The therapies of lung cancer include surgical resection, radiotherapy, chemotherapy, targeted therapy and immunotherapy. However, these therapies have certain limitations, severe toxic and side effects, and high costs. Therefore, it is urgent to find drugs with appropriate price and reliable efficacy. Traditional Chinese medicine (TCM) is the treasure of China, with more than 5 000 years of practical experience. In ancient books, there are records of therapies for lung amassment and pneumothorax, and modern studies have proved that there are many advantages, such as multiple targets, slight side effect, wide sources and reliable effects, and it is often used as an auxiliary treatment for lung cancer. The clear mechanism of TCM against lung cancer remains to be solved. The studies on the effect of TCM against NSCLC mainly start at the effective ingredients of TCM and end at the efficacy, and explore the "process"—mechanism. At present, the mechanism of TCM against NSCLC includes inducing apoptosis and autophagy of tumor cells, inhibiting the growth, proliferation, metastasis and invasion of tumor cells, which rises to molecular and genetic level. Based on the above mechanism, aiming at the effect target and pathway, this paper summarizes the literatures of the mechanism of TCM against non-small cell lung cancer in recent years, and sorted out some anti-lung cancer TCM about property, flavor and meridian-tropism on the basis of previous studies, in order to provide ideas for scholars to study the mechanism and clinical application of TCM in resisting lung cancer, and references for the studies of the correlation between the lung cancer as well as property, flavor and meridian-tropism.

ABSTRACT

Objective@#To investigate the safety and feasibility of longitudinal transpancreatic U-sutures invaginated pancreatojejunostomy (Chen′s pancreaticojejunostomy technique) in laparoscopic pancreaticoduodenectomy (LPD) .@*Methods@#Clinical data of 116 consecutive patients who underwent LPD using Chen′s pancreaticojejunostomy technique in Hunan Provincial People′s Hospital from May 2017 to December 2018 were retrospectively analyzed. Among these patients, 66 were males and 50 were females. The median age was 58 years old (32-84 yeas old). All 116 patients underwent pure laparoscopic whipple procedure with Child reconstruction method, using Chen′s pancreaticojejunostomy technique. The intraoperative and postoperative data of patients were analyzed.@*Results@#All 116 patients underwent LPD successfully. The mean operative time was (260.3±33.5) minutes (200-620 minutes). The mean time of pancreaticojejunostomy was (18.2±7.6) minutes (14-35 minutes) . The mean time of hepaticojejunostomy was (14.6±6.3) minutes (10-25 minutes). The mean time of gastrojejunostomy was (12.0±5.5) minutes (8-20 minutes). The mean estimated blood loss was (106.0±87.6) ml (20-800 ml). Postoperative complications were: 11.2% (13/116) of cases had postoperative pancreatic fistula (POPF) , including 10.3% (12/116) of biochemical fistula and 0.9% (1/116) of grade B POPF, no grade C POPF occurred; 10.3% (12/116) had gastrojejunal anastomotic bleeding; 3.4% (4/116) had hepaticojejunal anastomotic fistula; 3.4% (4/116) had delayed gastric emptying; 4.3% (5/116) had localized abdominal infection; 12.1% (14/116) had pulmonary infection; postoperative mortality were 0(0/116) and 1.7% (2/116) within 30 days and 90 days, respectively. One patient died of massive abdominal bleeding secondary to Gastroduodenal artery pseudoaneurysm rupture, the other patient died of extensive tumor recurrence and metastasis after surgery.@*Conclusions@#Chen′s pancreaticojejunostomy technique is safe and feasible for LPD.It is an option especially for surgeons who have not completed the learning curve of LPD.

There were 3 males and 7 females, aged from 40 to 69 years, with an average age of 57 years. Patients received abdominal color Doppler ultrasound examination, magnetic resonance cholangiopancreatography, and upper abdominal spiral computed tomography (CT) thinly scanning + enhanced examination. Data of CT examination were imported into RVS. RVS was used to locate hepatolithiasis, relationship between stones and vessels, anatomy of bile ducts and vessels in hepatic hilus. Surgical methods included RVS-guided hilar cholangiotomy, biliary stricturoplasty, bilateral hepatojejunostomy, hepatic segmentectomy (lobectomy), and hepatolithotomy. Observation indicators: (1) surgical and postoperative situations; (2) typical case analysis; (3) follow-up. Follow-up using outpatient examination was performed to detect residual stones up to June 2019. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers.@*Results@#(1) Surgical and postoperative situations: 10 patients underwent RVS-guided surgeries successfully for complicated hepatolithiasis, with successful match in RVS (difference between CT images and ultrosound images <2 mm). No residual stone was identified by choledochoscope during operation. The operation time and volume of intraoperative blood loss were 285 minutes (range, 210-360 minutes) and 200 mL (range, 100-600 mL), respectively. 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.
