ABSTRACT
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. All the 166 patients underwent precise hepatectomy combined with different methods of drainage, of which 28 cases underwent left hemihepatectomy, 11 cases underwent right hemihepatectomy, 1 case underwent liver resection of segment Ⅰ, 5 cases underwent liver resection of segment Ⅱ, 5 cases underwent liver resection of segment Ⅲ, 8 cases underwent liver resection of segment Ⅳ (left medial lobe), 3 cases underwent liver resection of segment Ⅴ, 2 cases underwent liver resection of segment Ⅵ, 2 cases underwent liver resection of segment Ⅷ, 68 cases underwent liver resection of segment Ⅱ and Ⅲ (left lateral lobe), 3 cases underwent liver resection of segment Ⅴ and Ⅵ, 6 cases underwent liver resection of segment Ⅴ and Ⅷ (right anterior lobe), 21 cases underwent liver resection of segment Ⅵ and Ⅶ (right posterior lobe), 1 case underwent liver resection of segment Ⅱ, Ⅲ and Ⅳa, 1 case underwent liver resection of segment Ⅴ, Ⅵ and Ⅶ, 1 case underwent liver resection of segment Ⅰ, Ⅱ, Ⅲ and Ⅳ. 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). Results of multivariate analysis showed that the number of previous surgeries ≥3 was an independent risk factor affecting the prognosis of precise hepatectomy in patients with recurrent unilateral hepato-lithiasis ( odds ratio=6.05, 95% confidence interval as 2.20?16.62, P<0.05). Conclusions:Precise hepatectomy is safe and effective for the treatment of patients with recurrent unilateral hepato-lithiasis. The number of previous surgeries ≥3 is an independent risk factor affecting the prognosis of precise hepatectomy in patients with recurren t unilateral hepatolithiasis.
ABSTRACT
Objective:To explore the postoperative biliary leakage and severe complication rate and its related risk factors of hepaticojejunostomy (HJ) for biliary disease.Methods:The clinical data of patients undergoing HJ for benign biliary diseases at the First Affiliated Hospital of Anhui Medical University from Jan 2003 to Dec 2017 were retrospectively analyzed. Multi-factor analysis was used to find a risk factor for postoperative bile leakage and severe complications.Results:Two hundred and eighty-three patients received HJ. The median age was 39 years.The short-term complication rate after surgery was 19.1% ( n=54), and the biliary leakage rate was 11.7% ( n=33), and the severe complication rate was 15.2% ( n=43). By multi-factor analysis: preoperative sepsis[ OR=3.875, 95% CI (1.583, 9.485), P=0.003], liver cirrhosis [ OR=3.212, 95% CI (1.001, 10.307), P=0.050], intraoperative blood loss≥400 ml [ OR=6.054, 95% CI (1.231, 29.781), P=0.027],postoperative hospitalization ≥9 days [ OR=6.738, 95% CI (2.287, 19.855), P=0.001] are the independent risk factors for postoperative bile leakage. Main bile duct stone[ OR=2.764, 95% CI (1.174, 6.510), P=0.020], preoperative sepsis [ OR=4.310, 95% CI (1.666, 11.149), P=0.003], intraoperative bleeding ≥400 ml [ OR=5.944, 95% CI (1.231, 29.781), P=0.022] and postoperative hospitalization ≥ 9 days [ OR=11.422, 95% CI (1.317, 49.859), P=0.001] are the independent risk factors for serious complications. Conclusions:HJ should be conducted when the sepsis was under control and sufficient bile drainage.The patients' condition should be comprehensively and accurately assessed before operation. The indications for partial hepatectomy need to be strictly defined.
ABSTRACT
Objective:To analyze the risk factors for postoperative pancreatic fistula after pancreaticoduodenectomy (PD).Methods:The clinical data of 185 patients undergoing PD who were admitted to the Hepatobiliary and Pancreatic Surgery Center of First Affiliated Hospital of Anhui Medical University from January 2014 to December 2018 were retrospectively analyzed. Risk factors for pancreatic fistula after PD were investigated using univariate and multivariate logistic regression analyses.Results:Among 185 patients, pancreatic fistula occurred in 37 patients after PD, and the incidence was 20.0%. Of 34 patients (18.4%) developed grade B pancreatic fistula, and 3 patients (1.6%) developed grade C pancreatic fistula. There were two deaths directly related to postoperative pancreatic fistula (5.4%). Patients with grade B and C postoperative pancreatic fistula had significantly increased hospitalization time and medical expenses. Univariate analysis identified that pancreatic duct diameter ≤3 mm, soft pancreas and serum albumin ≤30 g/L(χ 2=7.236, 6.948, 8.063, all P<0.05) were risk factors for pancreatic fistula after PD. Multivariate logistic regression analysis identified that pancreatic duct diameter≤3mm, soft pancreatic texture and serum albumin ≤30 g/L ( OR=0.401, 0.629, 0.326, 95% CI 0.167-0.968, 0.411-0.963, 0.150-0.711, all P<0.05) were independent risk factors for pancreatic fistula after PD. Postoperative pancreatic fistula patients had a median survival time of 827.0 days, 1-year survival rate was 94.7%, and a 3-year survival rate was 35.8%. There was no significant correlation between postoperative pancreatic fistula and postoperative survival(χ 2=1.367, P=0.242). Conclusions:Patients with a smaller pancreatic duct diameter (≤3 mm), soft pancreatic texture, and low postoperative albumin(≤30 g/L) may have a high incidence of pancreatic fistula after PD. Postoperative pancreatic fistula did not significantly affect the patients′ long-term survival.
ABSTRACT
Objective:To explore the clinicopathological characteristics of the primary hepatic adenosquamous carcinoma(ASC).Methods:A retrospective analysis was performed on the clinical data of 5 ASC patients admitted to the First Affiliated Hospital of Anhui Medical University from 2006 to 2019 who underwent surgical resection and were pathologically confirmed.Results:Among the 5 ASC cases, there were 4 males and 1 female. The age ranged from 48 to 73 years. As for the initial symptoms, there were 5 cases complaining upper abdominal pain, 2 cases presenting fever, 1 case presenting weight loss and 1 case presenting jaundice. CA19-9 was significantly higher than normal in 4 cases, while AFP was normal in all. None had definite preoperative diagnosis.All the 5 patients underwent surgical resection with pathology proved primary hepatic ASC. Lymph node metastasis was found in 4 cases and nerve invasion in 2 cases. There were 4 cases at TNM stage ⅣA, one at stage ⅠB. The median disease-free survival (DFS) was 5 months and the overall survival (OS) was 9 months.Conclusions:Primary hepatic adenosquamous carcinoma is a rare type of liver malignant tumor with an extremely poor prognosis. Surgical resection helps little in improving the prognosis.
ABSTRACT
Objective:To investigate the incidence and related risk factors related to early postoperative complications after hepaticojejunostomy surgery for iatrogenic bile duct injury.Methods:A retrospective analysis was made on the data of 110 cases undergoing a hepaticojejunostomy at the First Affiliated Hospital of Anhui Medical University and Anhui Provincial Hospital from January 2001 to December 2018. The univariate and multivariate analyses were performed to explore the impact risk factors on the short-term complications.Results:Patients′ median age was 44 years old. The short-term postoperative complication rate was 35.5% and the serious complication rate was 17.3%. Univariate analysis showed that male, a failed repair was attempted before referral, intraoperative bleeding>400 ml, and duration of surgery were significantly related to the occurrence of early postoperative complications (all P<0.05). Multivariate analysis showed that male, pre-referral failed surgical repair, preoperative bile leakage, initially combined with hepatectomy, and intraoperative bleeding>400 ml were independent risk factors for postoperative short term complications (all P<0.05). Univariate and multivariate analysis of early postoperative severe complications(Clavien-Dindo≥Ⅲ) revealed that pre-referral surgical repair, combined liver resection, and intraoperative bleeding>400 ml can significantly affect the occurrence of early postoperative severe complications (all P<0.05) . There was no significant correlation between the timing of biliary repair and the occurrence of complications ( P>0.05). Conclusions:Upon the occurrence of iatrogenic bile duct injury, the surgeon is advised to refrain from doing a repair instead sending the patient to a referral hospital. If bile leakage persists before surgery, sufficient bile drainage should be given priority to control infection.
ABSTRACT
Objective To evaluate 3D visualization technology in the preoperative planning of hepatic malignancy surgery.Methods The clinical data of 42 patients with hepatic malignancy undergoing radical resection after 3D reconstruction assessment from Feb 2015 to Feb 2018 in our center was retrospectively studied.The predicted resected liver volume were compared with that of resected specimen.Results Surgery was successful in all the 42 patients,and there were no operative deaths.The average operation time was (303 ± 109) minutes,the average intraoperative blood loss was (510 ±482) ml,and 28 patients had intraoperative hepatic inflew occlusion.Postoperative Clavien Ⅲ complications occurred in 4 cases.In terms of the resection liver volume,there was no significant difference between the predicted results (PELV) and actual results [resection liver volume (AELV):(1 143 ± 584) ml vs.(1 091 ± 570) ml,t =0.414,P ＞ 0.05].There is a strong positive correlation between AELV and PELV (r =0.996,P ＜ 0.01).PELV was highly consistent with AELV data (ICC =0.998).Conclusion Three-dimensional visualization technology can accurately reflect the anatomic relationship between intrahepatic tumors and vessels,and correctly assess liver volume,guide surgical resection,thus,it can instruct radical resection of liver malignancy.
ABSTRACT
Retrospective analysis of clinical data was conducted in the patients with secondary hyperparathyroidism( SHPT) undergone parathyroidectomy ( PTX ) in our department from September 2015 to September 2016. Uni- and multivariate analyses were conducted to define independent influencing factors for persistent severe hypocalcemia. The results showed that 27 cases(31％ ) suffered from persistent severe hypocalcemia in a total of 87 patients. Univariate analysis revealed that age, weight, hospitalization time after operation, the year of increased serum creatinine, preoperative alkaline phosphatase ( ALP), preoperative intact parathyroid hormone (iPTH), preoperative albumin, postoperative 1 d serum calcium and phosphorus level, renal hypertension, and degeneration of bone were risk factors of persistent severe hypocalcemia. Multivariate analysis revealed that the year of increased serum creatinine, preoperative ALP, and preoperative albumin were the independent influence factors for persistent severe hypocalcemia.
ABSTRACT
Purpose To investigate the clinicopathological characteristics and treatment of combined hepatocellular carcinoma-cholangio carcinoma (cHCC-CC).Methods 24 cases of cHCC-CC were collected.The clinical pathological characteristics,imaging,immunophenotyping and clinical features were retrospectively analyzed and reviewed the literature.Results There were 18 males and 6 females in 24 cases of cHCC-CC.The age ranged from 36 to 68 years (mean age was 54.38).Tumour location:right hepatic lobe in 15 cases,left hepatic lobe in 6 cases,both left lobe and right hepatic lobe in 1 case,hepatic caudate and left lateral lobe in 1 case,diffuse nodular liver tumors in 1 case.Grossly,the texture and color of tumor was related to the composition of tumor.Microscopically,classic cHCC-CC had two areas composed of hepatocellular carcinoma area and cholangiocar cinoma area of mixed distribution or migration distribution.3 cases were cHCC-CC with stem cell properties (cholangiolocellular carcinoma type,CLC type).Immunohistochemical staining revealed that HCC like area mainly expressed CD10,CK8,Hepatocyte and CD10,cHCC-CC area expressed CK7 and EMA.CLC type expressed the immunophenotypic features of intermediate type of HCC.Conclusion The clinical manifestations of cHCC-CC are not specific,the preoperative diagnosis is difficult,and it should be combined with pathological characteristics,imaging features and immunophenotype diagnosis.
ABSTRACT
Objective To study the clinical effect of total parathyroidectomy with subcutaneous autotransplantation (TPTX + AT) in the treatment of secondary hyperparathyroidism(SHPT) in patients with chronic renal failure.Methods One hundred and thirty-four patients undergoing TPTX + AT in our hospital from January 2013 to October 2014 were includud in this study.The preoperative,postoperative and follow-up intact parathyroid hormone (iPTH),serum calcium,serum phosphorus and calcium-phosphorus product were statistically analyzed.The Kidney Disease Quality of Life Short Form (KDQOL-SFTM) scale was used to evaluate quality of life before and one year after parathyroidectomy.Postoperative complications and recurrence were observed.Results Postoperative iPTH,serum calcium,serum phosphorus and calciumphosphorus product decreased significantly compared with that before surgery.The difference had statistical significance (all P ＜ 0.05).One patient died in perioperative period.Temporary injury of recurrent laryngeal nerve was found in eight patients.Early postoperative hypocalcemia was frequently seen in 124 patients (92.5％) and in 7 cases (5.2％) occured intractable hypocalcemia.The quality of life was significantly improved one year after parathyroidectomy.Recurrence developed in 5 patients after operation.Conclusions TPTX + AT is safe and effective in the treatment of SHPT in patients with chronic renal failure and can significantly improve the patient's quality of life.
ABSTRACT
Objective To compare the effects of intramuscular or subcutaneous forearm parathyroid autotransplantation after total parathyroidectomy on patients with renal hyperparathyroidism.Methods From Jan.2012 to Dec.2013,total parathyroidectomy was carried out in 90 patients with renal hyperparathyroidism.According to the location of their parathyroid autograft,patients were divided into intramuscular group (n =39)and subcutaneous group(n =51).One patient in the intramuscular group and two in the subcutaneous group were excluded for the high levels of intact parathyroid hormone (iPTH) the day after operation.iPHT was analyzed 2 weeks,1 month,3 and 6 months after surgery.Results The time of autotransplantation was significantly shorter in subcutaneous group than in intramuscular group (11.46 (2.63) min vs 22.12 (3.78) min;t =0.632,P ＜ 0.05).iPTH levels were significantly lower in subcutaneous group than in intramuscular group 2 weeks after operation (P ＜ 0.05).There was no significant difference between the 2 groups regarding iPTH levels at 1 month,3 or 6 months after surgery.In the follow-up one patient in intramuscular group and one in subcutaneous group had graft-dependent hyperparathyroidism.Conclusion As compared to intramuscular parathyroid autotransplantation,subcutaneous parathyroid autotransplantation has advantages of simpler to operate,shorter autoimplantation time and easier to autograftectomy.
ABSTRACT
Objective To compare the complication and long-term efficacy of standard and extended pancreaticoduodenectomy for carcinoma of the head of pancreas by meta-analysis.Methods A literature search was performed of PubMed,Web of Science,Springer,WanFang,CNKI and CBMDisc databases from January 1990 to August 2014.Qualitative analysis of these literatures was conducted using Jadad evaluation.Patients with pancreatic head carcinoma undergoing extended radical resection and standard radical resection were divided into treatment group (extended pancreaticoduodenectomy group,EPD) and control group (standard pancreaticoduodenectomy group,SPD),respectively.Based on the heterogeneity test,meta-analysis of a fixed-or random-effect model were used.Results A total of 5 studies suitable for the selection criteria were chosen,involving 597 patients (299 in EPDs and 298 in SPDs).The results of meta-analysis showed that the EPDs have significantly longer operative time (MD =64.36,95％ CI =23.88-104.85,P =0.002) and more dissected lymph nodes (MD =16.45,95％ CI =9.61-23.29,P ＜ 0.000 01) than SPDs.There was no statistical difference (OR =1.76,95 ％ CI =0.66-4.65,P =0.26) in postoperative complications (46.3％ vs 36.0％) mortality (OR =1.31,95％ CI =0.47-3.69,P =0.61),1-year survival rate (OR =0.70,95 ％ CI =0.49-0.99,P =0.05),3-year survival rate (OR =0.79,95％ CI =0.55-1.15,P =0.22),and 5-year survival rate (OR =-0.02,95％ CI =-0.17-0.12,P =0.77).Conclusions Compared with standard radical resection,extended radical resection for pancreatic head carcinoma does not prolong the postoperative 1-,3-,and 5-year survival rates with comparable postoperative mortality and morbidity and prolonged operative time.
