ABSTRACT
Objective:To investigate the clinical characteristics of choledocholithiasis com-bined with periampullary diverticulum and influencing factor for difficult cannulation of endoscopic retrograde cholangiopancreatography (ERCP).Methods:The retrospective case-control study was conducted. The clinical data of 1 920 patients who underwent ERCP for choledocholithiasis in 15 medical centers, including the First Hospital of Lanzhou University, et al, from July 2015 to December 2017 were collected. There were 915 males and 1 005 females, aged (63±16)years. Of 1 920 patients, there were 228 cases with periampullary diverticulum and 1 692 cases without periampullary diverticulum. Observation indicators: (1) clinical characteristics of patients with choledocholithiasis; (2) intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis; (3) influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and com-parison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Logistic regression model was used for univariate and multivariate analyses. Results:(1) Clinical characteristics of patients with choledocholithiasis. Age, body mass index, cases with complications as chronic obstructive pulmonary disease, diameter of common bile duct, cases with diameter of common bile duct as <8 mm, 8?12 mm, >12 mm, diameter of stone, cases with number of stones as single and multiple were (69±12)years, (23.3±3.0)kg/m 2, 16, (14±4)mm, 11, 95, 122, (12±4)mm, 89, 139 in patients with choledocholithiasis combined with periampullary diverticulum, versus (62±16)years, (23.8±2.8)kg/m 2, 67, (12±4)mm, 159, 892, 641, (10±4)mm, 817, 875 in patients with choledocholithiasis not combined with periampullary diver-ticulum, showing significant differences in the above indicators between the two groups ( t=?7.55, 2.45, χ2=4.54, t=?4.92, Z=4.66, t=?7.31, χ2=6.90, P<0.05). (2) Intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis. The balloon expansion diameter, cases with intraoperative bleeding, cases with hemorrhage management of submucosal injection, hemostatic clip, spray hemostasis, electrocoagulation hemostasis and other treatment, cases with endoscopic plastic stent placement, cases with endoscopic nasal bile duct drainage, cases with mechanical lithotripsy, cases with stone complete clearing, cases with difficult cannulation, cases with delayed intubation, cases undergoing >5 times of cannulation attempts, cannulation time, X-ray exposure time, operation time were 10.0(range, 8.5?12.0)mm, 56, 6, 5, 43, 1, 1, 52, 177, 67, 201, 74, 38, 74, (7.4±3.1)minutes, (6±3)minutes, (46±19)minutes in patients with choledocholithiasis combined with periampullary diverticulum, versus 9.0(range, 8.0?11.0)mm, 243, 35, 14, 109, 73, 12, 230, 1 457, 167, 1 565, 395, 171, 395, (6.6±2.9)minutes, (6±5)minutes, (41±17)minutes in patients with choledocholithiasis not combined with periampullary diverticulum, showing significant differences in the above indicators between the two groups ( Z=6.31, χ2=15.90, 26.02, 13.61, 11.40, 71.51, 5.12, 9.04, 8.92, 9.04, t=?3.89, 2.67, ?3.61, P<0.05). (3) Influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Results of multivariate analysis showed total bilirubin >30 umol/L, number of stones >1, combined with periampullary diverticulum were indepen-dent risk factors for difficult cannulation in patients with periampullary diverticulum who underwent ERCP for choledocholithiasis ( odds ratio=1.31, 1.48, 1.44, 95% confidence interval as 1.06?1.61, 1.20?1.84, 1.06?1.95, P<0.05). Results of further analysis showed that, of 1 920 patients undergoing ERCP for choledocholithiasis, the incidence of postoperative pancreatitis was 17.271%(81/469) and 8.132%(118/1 451) in the 469 cases with difficult cannulation and 1 451 cases without difficult cannula-tion, respectively, showing a significant difference between them ( χ2=31.86, P<0.05). In the 1 692 patients with choledocholithiasis not combined with periampullary diverticulum, the incidence of postopera-tive pancreatitis was 17.722%(70/395) and 8.250%(107/1 297) in 395 cases with difficult cannula-tion and 1 297 cases without difficult cannulation, respectively, showing a significant difference between them ( χ2=29.00, P<0.05). In the 228 patients with choledocholithiasis combined with peri-ampullary diverticulum, the incidence of postoperative pancreatitis was 14.865%(11/74) and 7.143%(11/154) in 74 cases with difficult cannulation and 154 cases without difficult cannulation, respectively, showing no significant difference between them ( χ2=3.42, P>0.05). Conclusions:Compared with patients with choledocholithiasis not combined with periampullary divertioulum, periampullary divertioulum often occurs in choledocholithiasis patients of elderly and low body mass index. The proportion of chronic obstructive pulmonary disease is high in choledocholithiasis patients with periampullary diverticulum, and the diameter of stone is large, the number of stone is more in these patients. Combined with periampullary diverticulum will increase the difficult of cannulation and the ratio of patient with mechanical lithotripsy, and reduce the ratio of patient with stone complete clearing without increasing postoperative complications of choledocholithiasis patients undergoing ERCP. Total bilirubin >30 μmol/L, number of stones >1, combined with periampullary diverticulum are independent risk factors for difficult cannulation in patients of periampullary diverticulum who underwent ERCP for choledocholithiasis.
ABSTRACT
Objective:To explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.
ABSTRACT
Objective:To investigate characteristics of the 18F-flurodeoxyglucose ( 18F-FDG) uptake intensity and ranges in distinct hepatic alveolar echinococcosis lesions. Methods:The clinical data of 39 patients with position emission tomography during Jan 2017 to Dec 2019 in the First Affiliated Hospital of Xinjiang Medical University were enrolled. Among them, there were 17 males and 22 females, aging from 15 to 65 years (median 34 years). Lesions were classified into six groups based on heterogenic scales of calcification and liquefaction: A. non-calcified and non-liquefied ( n=7); B. obvious calcified and non-liquefied ( n=7); C. partial calcified and partial liquefied( n=10); D. obvious calcified and partial liquefied ( n=5); E. partial calcified and subtotal liquefied ( n=5); F. obvious calcified and subtotal liquefied ( n=5). Tumor to background ratio (TBR) and width (W) of lesion infiltrative boundary were measured and calculated. Statistical comparison using Mann-Whitney U test as well as correlation analysis was performed. Results:TBR values [ M( Q1, Q3)] for each group were 4.40(3.66, 7.03), 2.55(1.69, 3.60), 3.73(3.37, 5.21), 2.90(2.75, 3.60), 3.80(3.49, 6.36), 2.49(2.21, 3.97), among which A>B, A>D, A>F, C>B, E>B ( U=3.0, 4.0, 4.5, 11.0, 5.0, all P<0.05); From the perspective of the calcification in each group, it was found that the lighter the calcification was, the greater the TBR value was. W values [ M( Q1, Q3)] for each group were [12.5(10.0, 19.5), 11.2(10.5, 12.5), 12.2(10.9, 13.2), 7.8(7.3, 9.3), 10.0(7.3, 13.4), 7.3(6.8, 7.6)] mm, among which A>D, A>F, B>D, B>F, C>D, C>F (all U=0, all P<0.05); According to the degree of calcification and liquefaction of lesions in each group, the lighter the calcification was, the greater the W value was; The heavier the liquefaction was, the smaller the W value was. A mild strength linear correlation has been observed between the TBR value and W value ( r=0.4136, P<0.05). Conclusions:Less calcification and liquefaction implicated higher 18F-FDG uptake intensity and wider range. Radical resection margins and tissue sampling should be individualized based on different lesion features in surgical treatment.
ABSTRACT
Objective:To evaluate the safety and efficacy of endoscopic retrograde biliary drainage (ERBD) for acute obstructive suppurative cholangitis (AOSC) in the elderly.Methods:A retrospective analysis was performed on the clinical data of AOSC patients admitted to the First Affiliated Hospital of Xinjiang Medical University from January 2018 to January 2020. Patients aged 75 years and over ( n=49) were assigned to the elderly group and patients under 75 years old were assigned to the control group ( n=63). General data, American Society of Anesthesiologists (ASA) grading, procedure-related indicators, incidence of postoperative complications and mortality were compared. Results:There were significant differences in age (82.6±5.1 years VS 64.6±4.5 years, t=19.98, P<0.001), albumin levels (29.1±5.9 g/L VS 34.6±8.8 g/L, t=-3.94, P<0.001) and ASA grade ( χ2=8.37, P=0.015) in the elderly group and the control group . The elderly group were accompanied by more basic diseases, i.e. hypertension [57.14% (28/49) VS 34.9% (22/63), χ2=5.51, P=0.019], coronary heart disease [55.1% (27/49) VS 27.0% (17/63), χ2=9.14, P=0.003], chronic obstructive pulmonary diseases/asthma [24.5% (12/49) VS 6.3% (4/63), χ2=7.41, P=0.006]. There were no significant differences in the operation time (31.4±8.1 min VS 30.4±8.0 min, t=-0.61, P=0.543) or hospital stay (6.1±1.7 days VS 5.7±1.4 days, t=1.35, P=0.182). The incidences of postoperative complications were 14.3% (7/49) in the elderly group and 12.7% (8/63) in the control group, showing no significant difference ( χ2=0.06, P=0.807). No ERBD-related death was observed in either group during hospital stay. Conclusion:For elderly patients with AOSC over 75 years old, emergency ERBD, which can quickly relieve the disease, is safe and effective. Advanced age is not an absolute contraindication for emergency ERBD.
ABSTRACT
Objective:To investigate the feasibility, safety and efficacy of simultaneous combined surgery for hepatic and renal cystic echinococcosis (CE).Methods:Clinical data of consecutive 11 hepatic and renal CE patients undergoing surgical treatment at the First Affiliated Hospital of Xinjiang Medical University from Oct 2009 to Feb 2017 were analyzed retrospectively.Results:There were 8 males and 3 females, median age was 44 years (22-60 years). Main symptoms were abdominal and/or flank pain and fever; nine and 2 patients respectively had cysts in liver plus right kidney and left kidney; median volume of cyst load for each patient was 944.1 cm 3 (67.1-9 310.4 cm 3). All patients were treated simultaneously by combined surgery, including total and subtotal cystectomies, hepatic or renal resections as well as extra lesions resection. All surgeries went uneventfully, radical rate was 63.6% (7/11), There was no postoperative liver or kidney dysfunctions. Median operative time, bleeding and length of hospital stay were 2.5 h (1.4-4.5 h), 100 ml (50-200 ml) and 7 d (5-10 d) respectively. All were followed-up for median 42 mouths (34-123 mouths) and all doing well without disease recurrence. Conclusions:Simultaneous combined surgery for recurrent or primary hepatic and renal double organ CE patients could be a feasible and effective approach.
ABSTRACT
Objective:To investigate the safety and feasibility of hepatectomy in the treatment of hepatic alveolar echinococcosis with secondary cavernous transformation of the portal vein.Methods:The clinical data of 7 patients undergoing surgery at the First Affiliated Hospital of Xinjiang Medical University from Jan 2010 to Dec 2019 were retrospectively analyzed.Results:There were 1 case of cavernous type Ⅰ transformation of the portal vein and 6 cases of type Ⅱ. All patients underwent partial hepatectomy. The average operation time was (9.24±4.09) h. Two patients underwent resection of cavernous segment of portal vein and reconstruction by graft, Albendazole was taken orally for 2 years after discharge. Anticoagulants were taken orally in patients with artificial vascular reconstruction. No recurrence and vascular complications were found. Five patients underwent palliative resection without resection of the cavernous segment of the portal vein. During the follow-up, cavernous transformation of the portal vein progressed in 3 patients, 2 of them esophageal varices rupture and bleeding.Conclusion:Radical hepatectomy and revascularization are the first choice for the treatment of hepatic alveolar echinococcosis complicated with secondary cavernous transformation of portal vein the result was fair.
ABSTRACT
Human alveolar echinococcosis is a chronic infectious disease caused by Echinococcus multilocularis infection. It predominantly injuries the liver and grows like the malignant tumor. The therapeutic options and prognosis depend on types of human alveolar echinococcosis, clinical stages, biological activity, vascular invasion, pathological characteristics, and patient's immune status. However, despite of multiple classification methods, there are still lacking of comprehensive typing schemes. which leads to inappropriate diagnosis and therapy. This research systematically reviewed the recent studies on human alveolar echinococcosis at home and abroad and analyzed the classifications based on ultrasound, computer tomography, magnetic resonance imaging, positron emission computed tomography, serology and pathology, and some novel technologies and summarized the individual advantage and disadvantage for each classification Relationships and their advantages plus disadvantages have been assessed comprehensively. Meanwhile, the possible reference factors or theoretical basis for optimized future classification are proposed, in order to establish a unified classification system to provide guidance for clinical diagnosis and treatment.
ABSTRACT
Objective:To explore the curative effect of laparoscopic surgery for hepatic cysticercosis.Methods:Search the literature from February 2010 to February 2020 on literature platforms such as Wanfang Data, VIP, CNKI, Pubmed, ScienceDirect, Web of Science, etc. the key words were "肝囊型包虫病" , "细粒棘球蚴" , "手术" , "开腹手术" , "腹腔镜" , "微创手术" , " echinococcosis " , " liver or hepatic " , " laparoscopic or minimal invasive " . Data on intraoperative indicators (e.g., operation time, bleeding volume), postoperative complications, hospital stay, recurrence rate, etc. in the literature included in the study were extracted and meta-analyzed.Results:A total of 9 articles were included, including 2 prospective studies and 7 retrospective case-control studies. A total of 1031 patients were enrolled, including 272 in the laparoscopic group and 759 in the laparotomy group. The results of the meta-analysis showed that the total postoperative complication rate in the laparoscopic group was lower than that in the laparotomy group ( OR=1.64, 95% CI: 1.10-2.45, P<0.05). Incision-related complications in the laparoscopy group and laparotomy group the difference was statistically significant ( OR=2.81, 95% CI: 1.03-7.70, P<0.05), and the hospital stay in the laparoscopic group was shorter ( SMD=1.21, 95% CI: 0.47-1.96, P<0.05). There was no significant difference between the two groups in operation time, postoperative bile leakage, residual cavity infection and effusion, and postoperative recurrence rate ( P>0.05). Conclusions:Under the premise of strictly grasping the indication of laparoscopic surgery, the incidence of complications after laparoscopic surgery is low, the hospitalization time is short.
ABSTRACT
Compression by hepatic hydatid lesions may invade the portal vein and cause cavernous transformation of the portal vein (CTPV), which has difficulties and high risks in surgery, and conventional hepatectomy cannot achieve radical treatment. This article reviews the etiology, classification, clinical manifestations, and auxiliary examinations of hepatic echinococcosis with CTPV and summarizes the treatment strategies for this disease. It is believed that the treatment of hepatic echinococcosis with CTPV should combine the resection of hydatid lesions with the effective relief of portal hypertension, and revascularization and ex-vivo liver resection with auto-transplantation play an important role in radical resection.
ABSTRACT
Objective:To explore the application of perioperative nutrition management strategy in patients with hepatic cystic echinococcosis.Methods:From October 2017 to February 2019, 53 patients with hepatic cystic echinococcosis who met the inclusion criteria were selected as the control group. Another 53 patients from June 2018 to January 2019 were collected as the experimental group, the nutritional index, liver function, complication rate and postoperative recovery were compared between the two groups.Results:The levels of retinol-binding protein, prealbumin and transferrin were (24.32 ± 3.76) μg/L, (167.00 ± 24.12) mg/L, (2.08 ± 0.43) μg/L on the day of admission in the experimental group, and one day before the operation were (27.78± 4.98) μg/L, (245.00 ± 22.02) mg/L,(2.47 ± 0.54)μ g/L, there was no significant difference ( t=0.576-3.552, P < 0.05). The incidence of infection, biliary leakage and hemorrhage in the experimental group were 0, 1.89% (1/53) and 0 respectively, which were lower than 9.43% (5/53), 13.21% (7/53), 11.32% (6/53) in the control group ( χ2 value was 4.867, P < 0.05). The aspartate aminotransferase and alanine aminotransferase of the experimental group on the 7th day after operation were (51.50 ± 6.30), (29.54 ± 2.03) U/L, which were significantly different from (69.53 ± 7.07), (43.72±3.67) U/L of the control group ( t value was 2.032, 2.015, P<0.05). Anal exhaust, defecation time, hospitalization time and expenses in the experimental group were (15.89±8.34) h, (49.12±10.56) h, (8.69 ± 1.69) d, (2.84±1.37) thousand yuan, which were significantly different from (34.13±7.13) h, (63.45±11.03) h, (11.51±4.18) d, (3.76±1.53) thousand yuan in the control group. There was statistical significance ( t values were 3.372-12.592, P<0.05). Conclusions:The application of perioperative nutrition management strategy in patients with hepatic cystic echinococcosis can improve the nutritional status of patients during perioperative period, promote the recovery of liver function and reduce the occurrence of postoperative complications.

The average hospital stays after surgery in the three groups were 30.64±18.54 d, 25.94±16.37 d, 51.29±29.43 d ( P<0.05), There were significant statistical differences, and the results showed that the group B was significantly less than other two groups. The incidence of IVC related complications in group A and B was 20.0% and 9.7%. Among all the subjects, RHIVC stenosis was found in 9 patients and thrombus was formed in 4 patients in postoperative. Conclusions:RHIVC reconstruction methods can be selected appropriately according to the defect degree of lumen after resection.
ABSTRACT
Objective:To investigate the risk factors related to choledocholithiasis in gallstone patients.Methods:The clinical data of 140 patients with gallstones or gallstones complicated with choledocholithiasis treated at our hospital from Jan 2017 to Dec 2019 were analyzed retrospectively.Results:The results showed gallstones≥ 10 mm (χ 2=7.896, P=0.019), parapapillary diverticulum (χ 2=10.849, P=0.013), the number of gallstones (single vs. multiple) (χ 2=9.760, P=0.080), age ( t=2.767, P=0.006), diameter of common bile duct ( t=8.068, P=0.000), total bilirubin level ( t=2.372, P=0.019), alkaline phosphatase ( t=2.448, P=0.016), significantly related to the formation of common bile duct stones. Logistic regression analysis showed that gallstone ≥ 10 mm, common bile duct dilatation, parapapillary diverticulum and multiple gallstones were all independent risk factors for choledocholithiasis in gallstone patients. Conclusion:A variety of risk factors were responsible for the formation of choledocholithiasis in gallstone patients.
ABSTRACT
Objective:To analyze the treatment and the impact of brain metastases on patients with hepatic alveolar hydatid disease.Methods:The data of 11 patients with hepatic alveolar hydatidosis with brain metastases treated at the First Affiliated Hospital of Xinjiang Medical University from January 2014 to December 2019 were retrospectively analyzed. There were 7 males and 4 females. The age range was 19~49 years, with an average of 34 years. Of 11 patients, 7 were treated with surgery combined with drugs and 4 with drugs only. Analyze the treatment and results of patients.Results:Of the 7 patients who were treated with surgery and drugs, 2 patients underwent hepatectomy. They were treated with regular postoperative oral medication and were well on follow-up. Three patients underwent only brain surgery. On follow-up from 1 to 3 years, one patient developed pneumonia with atelectasis, another patient developed ascites and jaundice with physical decline. The third patient was stable and had an independent life. Two patients underwent partial hepatectomy and hydatidectomy, with one patient requiring repeated hydatidectomies. On follow-up for one of these 2 patients for 5 years, the patient was home bound and could not take care of himself. The other patient was followed up for 3 years and was stable, alive and able of self-care. Four patients were treated with albendazole liposome, including one patient who developed ascites, a second one with weight loss, physical decline, limb edema and a third one with pleural effusion, pelvic effusion and pneumonia. These patients were still alive with improvement of symptoms on supportive treatment.Conclusion:The treatment of hepatic alveolar hydatidosis with brain metastases is still mainly surgery and anti-hydatid drugs. The prognosis of most patients was poor. The surgical principle is neurosurgery first, followed by surgery on liver, lung, spleen and other organs involved by hydatid disease.
ABSTRACT
Objective:To study the impact of selective occlusion of hepatic arterial blood flow in external capsule excision for hepatic cystic echinococcosis.Methods:A retrospective analysis was conducted on the data of 80 patients with hepatic cystic echinococcosis who underwent surgical treatment from January 2017 to January 2019 in the First Affiliated Hospital of Xinjiang Medical University. There were 36 males and 44 females, with an average age of 47 years. All patients underwent external capsule excision of hepatic cystic echinococcosis. According to the type of intraoperative blood flow occlusion, the patients were divided into: group A ( n=42), selective occlusion of hepatic artery; group B ( n=38), Pringle’s maneuvre. The hospitalization stay, intraoperative blood loss, postoperative ventilation time and complications were compared between the two groups. The postoperative alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, and total bilirubin were compared between the two groups. Results:The intraoperative blood loss (215.7±29.6) ml, postoperative ventilation time (2.3±0.1)d, and hospital stay (11.6±1.0) d in group A were better than those in group B (254.8±20.6) ml, (3.2±0.2) d, (12.7±0.7) d, the differences were significant (all P<0.05). There were 4 patients (9.5%) who developed postoperative complications in group A and 5 patients (13.2%) in group B. There was no significant difference between the two groups ( P>0.05). Group A had better ALT, AST, albumin, and total bilirubin on day 3 after operation, and the differences were significant (all P<0.05). The ALT (62.8±5.2) U/L, AST (32.7±2.6) U/L, albumin (39.1±0.3) g/L, total bilirubin (12.1±0.5) μmol/L in Group A were better than group B (121.9±5.6) U/L, (53.9±8.0) U/L, (32.2±0.6) g/L, (19.3±0.9) μmol/L on day 5 after operation, the differences were significant (all P<0.05). Conclusion:Selective occlusion of the hepatic artery in external capsule excision for hepatic cystic echinococcosis was superior to the traditional Pringle’s maneuver in controlling intraoperative bleeding and postoperative liver function recovery.
ABSTRACT
Objective@#To investigate the feasibility and safety of the concept of enhanced recovery after surgery (ERAS) in the perioperative application of ambulatory laparoscopic cholecystectomy (ALC).@*Methods@#A retrospective analysis was made on 168 patients (ALC group) undergoing ALC in the daytime ward from Aug 2017 to Aug 2018 in our hospital vs conventional laparoscopic cholecystectomy CLC in the general ward in 165 patients (CLC group) . Clinical data, operation time, intraoperative blood loss, conversion to laparotomy, postoperative complication, readmission, pain score after 6h, patient satisfaction, first postoperative anal exhaust, average length of hospital stay, and hospitalization expenses were compared between the two groups.@*Results@#In the ALC group, the pain score, the first anal exhaust time, the average length of hospital stay, and the hospitalization cost were significantly lower than those in the CLC group. Compared with the CLC group, the satisfaction of patients in the ALC group was significantly improved. There was no significant difference in the incidence of postoperative complications (biliary leakage, postoperative bleeding, bile duct injury, infection of the incision) and readmission rate.@*Conclusion@#Use of enhanced recovery after surgery in laparoscopic cholecystectomy in day surgery is safe and feasible. It has many advantages such as reducing hospitalization costs and postoperative pain and accelerating postoperative recovery.
ABSTRACT
Objective@#To study the clinical outcomes using laparoscopic complete dissection of cysts, subtotal cystectomy and partial hepatectomy in the treatment of hepatic cystic echinococcosis.@*Methods@#A retrospective study was conducted on 40 patients with hepatic cystic echinococcosis treated by laparoscopic surgery from January 2014 to June 2018 at the First Affiliated Hospital of Xinjiang Medical University. According to the different surgical methods, these patients were divided into three groups: group A (n=14): the laparoscopic complete capsulectomy group, group B (n=14): the laparoscopic subtotal capsulectomy group, group C (n=12): the laparoscopic partial hepatectomy group. The operation time, intraoperative blood loss, time to pass first flatus, duration of drainage tube placement, days of hospitalization after operation, hospitalization expenses, complications of the residual cavity and local recurrence were compared among the 3 groups.@*Results@#In this study, all the 40 patients with hepatic cystic hydatidosis were cured, and no death occurred during the perioperative period. The intraoperative blood loss, postoperative duration of drainage tube placement, and hospitalization cost of the three groups were significantly the highest in group C (all P<0.05). The operative time and the time to pass first flatus in group C were both significantly greater than group B (P<0.05). The length of postoperative hospitalization in group A was significantly less than in group C (P<0.05). Postoperative recurrence and complications in group B were significantly worse than those in group A and group C (all P<0.05).@*Conclusion@#Laparoscopic complete dissection of the external capsule turned out to be the best laparoscopic treatment of hepatic cystic echinococcosis, followed by laparoscopic partial hepatectomy. Open surgery should be considered in patients with lesions which are evaluated preoperatively to have difficulty in carrying out laparoscopic complete dissection of capsule or partial hepatectomy.
ABSTRACT
Objective@#To analyze the changes of local immune cells in liver of mice caused by nanosecond pulse therapy for hepatocellular carcinoma.@*Methods@#Forty C57BL-6J of mice were randomly divided into four groups: negative control group (n=10), tumor group (n=10), surgical resection group (n=10) and nanosecond pulse group (n=10). Hepa 1-6 cells were injected into the left hepatic lobe of mice in tumor group, resection group and nanosecond pulse group to construct the orthotopic xenograft tumor model. Left hepatic lobectomy was performed in the surgical excision group and nanosecond pulse was performed in the nanosecond pulse group 7 days after the construction. All mice were sacrificed 7 days after the treatment. CD3＋ was detected by flow cytometry in the left hepatic lobe lesion, the nanosecond pulse group and the normal liver tissue of the right hepatic lobe in the liver and tumor groups of the blank control group. T, CD4＋T, CD8＋T, regulatory T cells (Treg), myeloid-derived suppressor cells (MDSC), natural killer cells (NK), B cells, and the ratio of CD4＋T to CD8＋T.@*Results@#In the blank control group, the tumor group the number of lesion in the mice and the pulse area of the nanosecond pulse group CD4＋T cells in blank control group (normal liver)>nanosecond pulse group>tumor group [(25.77±3.76)% vs. (15.72±2.70)% vs. (12.68±3.13)%, P<0.05]; CD8＋T cell tumor group>blank control group>nanosecond pulse group [(14.01±2.75)% vs. (13.99±1.41)% vs. (8.42±2.21)%, P<0.05]. The ratio of CD4＋T to CD8＋T in nanosecond pulse group > blank control group > tumor group [(1.90±0.17) vs. (1.86±0.32) vs. (0.93±0.21), P<0.05]; B cell nanosecond pulse group> blank control group > tumor group [(47.65±3.77)% vs. (33.74±3.91)% vs. (15.94±6.10)%, P<0.05]; MDSC cell tumor group > nanosecond pulse group > blank control group [(18.49±2.74)% vs. (8.41±3.05)% vs. (2.15±0.69)%, P<0.05]. However, CD3＋T cells, NK cells and Treg cells showed no statistical significance among the three groups (all P>0.05). Normal liver tissue in right lobe of liver in 4 groups the ratio of CD4＋T to CD8＋T in blank control group >nanosecond pulse group >surgical resection group >tumor group [(1.86±0.32) vs. (1.85±0.43) vs. (1.52±0.16) vs. (1.36±0.29), P<0.05]; B cell nanosecond pulse group >surgical resection group >blank control group> Tumor group [(46.85±8.30)% vs. (34.23±6.17)% vs. (33.74±3.91)% vs. (27.64±2.20)%, P<0.05]; Treg cell tumor group >resection group>nanosecond pulse group>blank control group [(26.34±6.23)% vs. (7.01±2.04)% vs. (3.63±1.59)% vs. (3.19±1.50)% , P<0.05]; MDSC in tumor group >resection group>nanosecond pulse group>blank control group [(12.22±2.02)% vs. (5.00±0.73)% vs. (2.87±0.96)% vs. (2.15±0.69)%, P<0.05]. However, there were no statistically significant differences in CD3＋T, CD4＋T, CD8＋T and NK cells among the four groups (all P>0.05).@*Conclusion@#Nanosecond pulse ablation of primary hepatocellular carcinoma of mice can induce immune response in ablation area and other hepatic lobes, which may be due to the anti-tumor immunity induced by nanosecond pulse.
ABSTRACT
