Single-incision laparoscopic transabdominal preperitoneal repair in the treatment of adult female patients with inguinal hernia

BACKGROUND Women have a 3%lifetime chance of developing an inguinal hernia,which is not as common in men.Due to its cosmetic benefits,single-incision laparoscopic transabdominal preperitoneal(SIL-TAPP)inguinal hernia repair is becoming in-creasingly popular in the management of inguinal hernia in women.However,there are no studies comparing the safety and applicability of SIL-TAPP repair with conventional laparoscopic transabdominal preperitoneal(CL-TAPP)inguinal hernia repair for the treatment of inguinal hernia in women.AIM To compare the outcomes of SIL-TAPP and CL-TAPP repair in adult female patients with inguinal hernia and to estimate the safety and applicability of SIL-TAPP repair in adult female inguinal hernia patients.METHODS We retrospectively compared the clinical information and follow-up data of fe-male inguinal hernia patients who underwent SIL-TAPP inguinal hernia repair and those who underwent CL-TAPP inguinal hernia repair at the Affiliated Hos-pital of Nantong University from February 2018 to December 2020 and assessed the long-term and short-term outcomes of both cohorts.RESULTS This study included 123 patients,with 71 undergoing SIL-TAPP repair and 52 un-dergoing CL-TAPP repair.The two cohorts of patients and inguinal hernia charac-teristics were similar,with no statistically meaningful difference.The rate of intraoperative inferior epigastric vessel injury was lower in patients in the SIL-TAPP cohort(0,0%)than in patients in the CL-TAPP cohort(4,7.7%)and was significantly different(P<0.05).In addition,the median[interquartile range(IQR)]total hospitalization costs were significantly lower in patients in the SIL-TAPP cohort[$3287(3218-3325)]than in patients in the CL-TAPP cohort[$3511(3491-3599)].Postoperatively,the occurrence rate of trocar site hernia was lower in the SIL-TAPP cohort(0,0%)than in the CL-TAPP cohort(4,7.7%),and the median(IQR)cosmetic score was significantly higher in the SIL-TAPP cohort[10(10-10)]than in the CL-TAPP cohort[9(9-10)].CONCLUSION SIL-TAPP repair did not increase the incidence of intraoperative and postoperative complications in female in-guinal hernia patients.Moreover,female inguinal hernia patients who underwent SIL-TAPP repair had a lower probability of trocar site hernia and inferior epigastric vessel injury than female inguinal hernia patients who un-derwent CL-TAPP repair.In addition,female inguinal hernia patients who underwent SIL-TAPP repair reported a more aesthetically pleasing postoperative abdominal incision.Therefore,SIL-TAPP repair is a better option for the treatment of inguinal hernias in women.

Comparative Analysis of the Efficacy of Transabdominal Pre-Peritoneal Vs Open Tension-Free Hernia Repair in Treating Inguinal Hernia

Objective:To investigate and analyze the clinical outcomes of inguinal hernia patients treated with transabdominal pre-peritoneal repair(TAPP)versus open tension-free hernia repair.Methods:The study was carried out from January 2021 to August 2023,and a total of 50 inguinal hernia patients were selected for this study.The patients were randomly divided into a study group(n=25)and a control group(n=25)by the numerical table method.The patients in the control group were treated with open tension-free hernia repair,whereas the patients in the study group were treated with TAPP.The surgical and postoperative recovery indexes,complication rates,and recurrence rates of the two groups were compared.Results:There was no significant difference in the operative time and intraoperative blood loss between the two groups(P>0.05),and the postoperative feeding time,time out of bed,and hospitalization time of the study group were shorter than those of the control group(P<0.05);the incidence rate of postoperative complications in the study group was lower than that in the control group(P<0.05);and there was no significant difference in the recurrence rate of the two groups after operation(P>0.05).Conclusion:Compared to open tension-free hernia repair,TAPP offers a shorter postoperative recovery duration and hospitalization time,and reduces the incidence of complications.Therefore,this surgical method should be popularized in the treatment of inguinal hernia.

Comparison of survival outcomes between transthoracic and transabdominal surgical approaches in patients with Siewert-Ⅱ/Ⅲesophagogastric junction adenocarcinoma:a single-institution retrospective cohort study

Objective： To compare the survival outcomes of transabdominal （TA） and transthoracic （TT） surgical approaches in patients with Siewert-II/III esophagogastric junction adenocarcinoma. Methods： This retrospective study was conducted in patients with Siewert-II/III esophagogastric junction adenocarcinoma who underwent either TT or TA operations in the West China Hospital between January 2006 and December 2009. Results： A total of 308 patients （109 in the TT and 199 in the TA groups） were included in this study with a follow-up rate of 87.3%. The median （P25, P75） number of harvested perigastric lymph nodes was 8 （5, 10） in the TT group and 23 （16, 34） in the TA group （P〈0.001）, and the number of positive perigastric lymph nodes was 2 （0, 5） in the TT group and 3 （1, 8） in the TA group （P〈0.004）. The 5-year overall survival （OS） rate was 36% in the TT group and 51% in the TA group （P=0.005）. Subgroup analysis by Siewert classification showed that 5-year OS rates for patients with Siewert II tumors were 38% and 48% in TT and TA groups, respectively （P=0.134）, whereas the 5-year OS rate for patients with Siewert III tumors was significantly lower in the TT group than that in the TA group （33% vs. 53%; P=0.010）. Multivariate analysis indicated that N2 and N3 stages, RI/R2 resection and a TT surgical approach were prognostic factors for poor OS. Conclusions： Improved perigastric lymph node dissection may be the main reason for better survival outcomes observed with a TA gastrectomy approach than with TT gastrectomy for Siewert III tumor patients.

Laparoscopic repair via the transabdominal preperitoneal procedure for bilateral lumbar hernia: Three cases report and review of literature

A lumbar hernia is a rare entity, and a bilateral lumbar hernia is much rarer. From May 2015 to October 2017, we treated only three patients with bilateral lumbar hernias. One patient came to the hospital presenting with right-sided abdominal pain, and the other two patients presented with bilateral lumbar masses. The previous bilateral lumbar hernia reported in the literature was repaired by open surgery. The laparoscopic approach via the transabdominal preperitoneal(TAPP) procedure with the self-gripping Parietex ProG rip? mesh was performed at our center. The laparoscopic repair was conducted by a skilled hernia surgeon, and was successfully performed in the three patients. The patients resumed a semiliquid diet and had no activity restriction after six hours following the operation. No antibiotics were used after the surgery. The operative times of the three patients were 120 min, 85 min, and 130 min. The blood loss volumes of the three patients were 20 mL, 5 mL, and 5 mL. The visual analogue scale pain scores of the three patients were 1, 2, and 2 on postoperative day 1, and were 1, 2, and 1 on postoperative day 3. No perioperative complications, such as bulge, wound infection and hematoma, occurred after the surgery. All of the patients were discharged on the third day after the operation. There was no chronic pain and no hernia recurrence during the follow-up. This study showed that the laparoscopic TAPP approach with the self-gripping mesh is safe and feasible, and can be considered an alternative method for the treatment of bilateral lumbar hernias.

Use of barbed suture for peritoneal closure in transabdominal preperitoneal hernia repair

AIM:To investigate the use of the V-Loc wound closure device for transabdominal preperitoneal hernia repair. METHODS:We performed conventional transabdominal preperitoneal hernia repair in 19 patients, including one single incisional case using V-Loc. Except for the use of V-Loc for peritoneal closure, the procedures were the same as those used in conventional techniques. RESULTS:Although the operators included 2 residents who have no experience in laparoscopic herniorrhaphy and intracorporeal suture, the operations were completed. We believe that V-Loc is especially suitable for inexperienced surgeons and the use of V-Loc reduces the operative time by a small amount but reduces operator stress significantly. CONCLUSION:We conclude that V-Loc is the ideal peritoneal closure device for transabdominal preperitoneal hernia repair.

Comparison of the application value of transvaginal ultrasound and transabdominal ultrasound in the diagnosis of ectopic pregnancy

BACKGROUND Ectopic pregnancy(EP) is one of the most common acute abdominal diseases in gynecology. Once the condition of EP is delayed, it may lead to massive hemorrhage, shock, and even death in a short time, seriously threatening the patient’s life. Early diagnosis is the key to preventing and improving the prognosis of EP.Transabdominal ultrasound(TAS) and transvaginal ultrasound(TVS) are the main diagnostic methods for abdominal diseases. The purpose of this study is to explore the application value and effect of TAS and TVS in the diagnosis of EP,hoping to provide more valuable references for the diagnosis of EP.AIM To explore the application value of TAS and TVS in the diagnosis of EP and to improve the level of clinical diagnosis.METHODS A total of 140 patients with EP admitted to our hospital from July 2018 to July 2020 were selected for this study. All patients were divided into two groups according to the examination methods. 63 patients who underwent abdominal ultrasound examination were set as the TAS group, while 77 patients who underwent TVS examination were set as the TVS group. We compared the diagnostic accuracy and misdiagnosis rates between the two types of ultrasound examinations, as well as the postoperative pathological results of the two diagnostic methods for different types of ectopic pregnancies. We also analyzed the sonograms for the presence of mixed ectopic masses,adnexal masses, ectopic gestational sacs, the presence or absence of visible embryo and fetal heart in the ectopic sac shadow, and the detection of fluid in the rectal fossa of the uterus, such as the adnexal area, yolk sac, and embryo, etc. In addition, the diagnosis time, days of gestational sac appearance, operation time, endometrial thickness, and blood flow resistance index were compared as well.RESULTS After performing both types of ultrasound examinations in 140 patients with EP, we found that the diagnostic accuracy of TVS was significantly higher than that of TAS, and the misdiagnosis rate was significantly lower than that of TAS. The differences were statistically significant(P < 0.05). In addition, the detection rate of TVS was better than that of TAS for the presence of mixed masses,adnexal masses, ectopic gestational sacs, the presence or absence of visible embryo and fetal heart in the shadow of the ectopic sac, and sonograms such as the adnexal area, yolk sac, and embryo,etc. The coincidence rate of its postoperative pathological examination results was significantly higher than those of TAS. The diagnosis time and the days of gestational sac appearance by TVS were significantly shorter than that by TAS, and the operation time was earlier than that by TAS.What’s more, the detection rates of the endometrial thickness ￡ 1.5 mm and blood flow resistance ￡0.5 were significantly higher in TVS diagnosis of EP than in TAS. All differences were statistically significant(P < 0.05).CONCLUSION Compared with TAS, TVS has the advantages of high detection accuracy and good sonogram performance.

Comparison of transthoracic and transabdominal surgical approaches for the treatment of adenocarcinoma of the cardia

Background and Objective: Transthoracic and transabdominal approaches are commonly used for the surgical treatment of adenocarcinoma of the cardia. Which approach is better has been controversial for quite a long time. Our study aimed to compare the surgical trauma, range of lymph node dissection, and the prognosis of the transthoracic and transabdominal approaches for the treatment of adenocarcinoma of the cardia. Methods: The medical records of 331 patients with adenocarcinoma of the cardia treated in our hospital between 1994 and 2003 were analyzed. Of the 331 patients, 284 underwent operation via transthoracic approach and 47 via transabdominal approach. Surgery-related status, postoperative complications, range of removed lymph nodes and prognosis of the two groups were compared. Results: There was no significant difference in surgery-related status and postoperative complications between the two groups (P >0.05). The mean number of removed lymph nodes from the thoracic cavity was much higher in transthoracic group than in transabdominal group (P < 0.001), while that from the abdominal cavity was similar in both groups (P = 0.404). The thoracic lymph node metastasis rate was 18.8% in transthoracic group and 13.3% in transabdominal group. The median survival time was 29 months in transthoracic group and 28 months in transabdominal group, and the 5-year survival rates were 34.9% and 40.1% (P= 0.599). Conclusions: For the surgical treatment of adenocarcinoma of the cardia, the surgical trauma of the transthoracic approach is similar with that of transabdominal approach. The transthoracic approach has the advantage in thoracic lymph node dissection. The two approaches have no obvious effect on the prognosis.

Recurrent abdominal pain due to small bowel volvulus after transabdominal preperitoneal hernioplasty:A case report and review of literature

BACKGROUND Compared with open mesh repair,transabdominal preperitoneal(TAPP)hernioplasty results in less chronic postoperative inguinal pain and faster postoperative recovery.However,it may still lead to rare but serious complications.Here we report a case of intestinal volvulus with recurrent abdominal pain as the only clinical symptom,which occurred 3 mo after TAPP repair for bilateral inguinal hernia.CASE SUMMARY A 50-year-old male patient underwent laparoscopic TAPP for bilateral inguinal hernias.After the operation,he experienced recurring pain in his lower right abdomen around the surgical area,which was relieved after symptomatic treatment.Three months after the surgery,the abdominal pain became severe and was aggravated over time.The whirlpool sign of the mesentery was seen on contrast-enhanced computed tomography(CT).Laparoscopic exploration confirmed that a barb of the V-Loc™suture penetrated the peritoneum,which caused the adhesion of the small intestinal wall to the site of peritoneal injury,forming intestinal volvulus.Since there was no closed-loop obstruction or intestinal ischemia,recurrent abdominal pain became the only clinical manifestation in this case.After laparoscopic lysis of adhesions and reduction of intestinal volvulus,the patient recovered and was discharged.CONCLUSION The possibility of intestinal volvulus should be considered in patients who experience recurrent abdominal pain following TAPP surgery during which barbed V-Loc sutures are used for closing the peritoneum.Contrast-enhanced CT and active laparoscopic exploration can confirm the diagnosis and prevent serious complications.

Transabdominal Pre-Peritoneal Mesh for Inguinal Hernia Repair with External Fixation versus Mesh Stapling

Background: It is unknown whether stapling the mesh affects recurrence rate, incidence of neuralgia, and port-site hernia. We chose to fix it to the exterior reducing port size, cost and pain, at the same comparing this with traditional mesh stapling. Methods: We conducted a prospective trial for laparoscopic TAPP inguinal hernia repair on 120 patients in which we fixed the mesh to the anterior abdominal wall using either two prolene threads that passed to the exterior and tied in place or traditional mesh stapling. Results: The operative time is ranged from 35 to 70 minutes for external fixation, 30 to 60 minutes for mesh stapling, and 4 to 51 months for follow-up, and no recurrence occurred in both groups during the procedure. Two cases with post TAPP pain in mesh stapling patients are discussed with reduction of the cost and port size in external fixation patients. Conclusion: It is not necessary to secure the mesh during laparoscopic TAPP inguinal hernia repair from the interior and it is fixed only to the exterior allowing a reduction in size of the ports and considerable reduction in cost with elimination of TAPP associated post operative pain.

Single Incision Laparoscopic Transabdominal Preperitoneal Repair for Strangulated Groin Hernia

Introduction: Single incision laparoscopic surgery (SILS) has become more popular for various surgical procedures including hernia surgery. Initial results of SILS in elective hernia repair were comparable to those of conventional laparoscopic approaches. However the use of SILS in emergency case has not been widely reported. This study aimed to evaluate the feasibility of the use of single incision laparoscopic transabdominal preperitoneal (TAPP) repair for patients presenting with strangulated groin hernia. Method: Emergency single incision laparoscopic TAPP repair were performed in our unit from June 2011 onwards for selected patients. Retrospectively data including the patient demographics, operative time, type of hernia, hospital stay, complications and recurrence rate were collected and analyzed. Result: There were a total of five patients in this series from June 2011 to June 2012. The median age was 62 years old with a male to female ratio of 4:1. Four patients had unilateral hernia (one femoral and three inguinal hernias) and one had bilateral hernia (unilaterally strangulated femoral hernia and bilaterally reducible indirect inguinal hernia). The median operative time was 75 minutes for patients with unilateral repair. None of the patients required bowel resection. The conversion rate to either conventional laparoscopic or open repair was zero. The median hospital stay was 2 days. No major complication or recurrence was detected. Conclusion: This series showed that single port laparoscopic TAPP repair for strangulated groin hernia is a feasible option with no major complication reported.

Laparoscopic Transabdominal Preperitoneal Mesh Hernioplasty: A Medical College Experience

Objectives: To determine the feasibility and patient’s outcome of laparoscopic transabdominal preperitoneal mesh hernioplasty for inguinal hernias. Patients and Methods: This study was carried out from March 2011 to April 2014. A total of 130 patients underwent laparoscopic transabdominal preperitoneal mesh hernioplasty (TAPP) for uncomplicated inguinal hernia. Of this, 10 patients presenting with bilateral inguinal hernias were operated in the single sitting. A 15 cm × 12 cm polypropylene mesh was used in all cases. Operative morbidity, postoperative pain, seroma formation, evidence of superficial infection, chronic groin pain and hernia recurrence were noted. The majority of the patients were discharged within 24 hours and follow-up was done at 1 week, 1 month, and 6 months. Results: 130 patients presenting with uncomplicated inguinal hernias were operated over a period of three years in the department of surgery, Govt. Medical College Srinagar. The mean age of the patients was 39.18 years (range: 18 - 70 years). The median duration of operation was 48.5 minutes (range: 18 - 120 minutes). None of the procedure was converted to open inguinal hernia repair. Postoperative pain was observed in 9.23% of the cases and was easily controlled by oral analgesics. Six patients (4.62%) developed seroma, out of which one required aspiration while others settled conservatively. Two patients (1.54%) developed wound infection and one patient (0.77%) had recurrence. None of the patients developed scrotal hematoma or neuralgia. Return to normal activity after TAPP repair was found to be after a median of 16.1 days. Conclusion: Transabdominal preperitoneal repair for inguinal hernia using proline mesh may be a safe and effective procedure with low morbidity, early return to normal activity and with a very low recurrence after six months follow-up.

Clinical study in diagnosis of placental implantation abnormality with transabdominal Doppler ultrasound

Objective: To evaluate the ultrasonographic charateristics and the diagnostic value in placental implantation abnormality (PIA) with transabdominal Doppler ultrasound, and improve the rate of diagnosis accuracy in the prenatal and postnatal of PIA with transabdominal Doppler ultrasound, for early diagnosis and treatment, to avoid hysterectomy caused by fatal bleeding. Methods: There were 61 cases complicated with PIA by operation and pathologically confirmed in our hospital. 33 cases were prenatal PIA, and 28 cases were postnatal PIA. The sonographic characteristics of PIA were summarized, the sensitivity and false negative rate of transabdominal Doppler ultrasound were analyzed with the results of surgical and pathological diagnosis. Results: In the images of prenatal PIA, the incidence of abundant blood flow signals in muscular layer of the placenta was the highest, which could reached 85.7%, followed by placenta 'vortex' and placenta previa;placental remnants were major sonographic performance in postnatal PIA, the incidence rate was 100%, followed by abundant blood flow signals in muscular layer of the placenta and disappeared boundary between myometrium and placenta. 14 cases could be diagnosed as prenatal PIA accurately by transabdominal Doppler ultrasound, the sensitivity was 42.4%, and the false negative rate was 57.6%. 21 cases could be diagnosed as postnatal PIA accurately by transabdominal Doppler ultrasound, the sensitivity was 75.0%, and the false negative rate was 25.0%. Conclusions: The specificity was low in prenatal PIA by transabdominal Doppler ultrasound, but the false negative rate was high. If necessary, the diagnostic accuracy could be improved combined with MRI. The specificity was much higher in postnatal PIA, and the false negative rate was low. The ultrasonography of PIA has some certain characteristics, we should strengthen the consciousness of the diagnosis in PIA, especially in the prenatal PIA, and improve the auxiliary diagnosis.

Evaluation of The Effectiveness of Abdominal and Vaginal B-Ultrasound in The Diagnosis of Acute Abdomen in Obstetrics and Gynecology

Objective: To explore the clinical effect of the combined application of abdominal and vaginal B-ultrasound in the diagnosis of acute abdomen in obstetrics and gynecology. Methods: Eighty patients admitted to our hospital from March 2023 to March 2024 were selected, all of whom were acute abdomen patients admitted to the Department of Obstetrics and Gynecology. In this study, the patients were divided into two groups. One group of 40 patients was given a simple abdominal B-ultrasound diagnosis (control group). The other group of 40 patients was given both abdominal and vaginal B-ultrasound examinations (experimental group). The diagnostic accuracy between the two groups was compared. Results: Patients in the experimental group had higher consistency rates with pathological diagnosis results in ectopic pregnancy rupture, embryonic arrest, acute pelvic inflammation, corpus luteum rupture, and intrauterine adhesions as compared to the control group. At the same time, the inspection accuracy rate of the experimental group (92.50%) was higher than that of the control group (70.00%) (P < 0.05). Conclusion: The combined application of abdominal and vaginal B-ultrasound in the diagnosis of acute abdomen was of great significance in improving the accuracy of clinical diagnosis and guiding doctors to provide effective treatment.

Analysis of the Efficacy of Prenatal B-Ultrasound in Diagnosing Fetal Abnormalities

Objective:To explore the positive significance of using prenatal B-ultrasound in diagnosing fetal abnormalities.Methods:A total of 200 pregnant women who visited Shaanxi Provincial People’s Hospital between January 2023 and January 2024 were recruited as the research subjects.All pregnant women received prenatal examinations.A retrospective analysis was carried out to analyze the positive significance of prenatal B-ultrasound examination in the diagnosis of fetal abnormalities.Results:Prenatal B-ultrasound examination detected 10 cases of fetal abnormalities,with a detection rate of 5.00%.When compared with the postnatal examination results of 5.50%,the difference was insignificant(P>0.05).Moreover,comparing the fetal limb abnormalities and cardiovascular abnormalities in prenatal B-ultrasound examination and postnatal examination,one case of congenital heart disease was missed in the prenatal B-ultrasound examination,and the others were consistent with the postnatal examination results,with a coincidence rate of 90.91%,indicating a high compliance rate.Conclusion:Fetal abnormalities have a great impact on mothers,babies,and families,and it is particularly important to strengthen diagnosis during this process.Prenatal B-ultrasound examination can improve the accuracy of diagnosis of fetal abnormalities and can be promoted in clinical practice as a basis for screening fetal abnormalities.

Problem analysis and solutions of the B-ultrasound-guided peripherally inserted central catheter process

Objective： The purpose of this study was to address the issues that occur during the B-ultrasound guided peripherally inserted central catheter（PICC） process and to give a summary of the effective management to these issues accordingly.Methods： The information was collected retrospectively on all of the 1950 PICCs inserted during the 2-year period from July 2013 to July 2015. PICC catheter insertion was performed using the Seldinger approach and was delivered from the basilic vein to the superior vena cava in a B-ultrasound guided manner. Moreover, the point raised during the PICC process would be treated immediately.Results： All of the PICCs were inserted successfully. The problems encountered are shown in the inserted central catheter（PICC） process, such as failures of venipuncture, the problem of inserting guide wire, the catheter was dif？cult to be delivered etc.Conclusions： The B-ultrasound guided approach enhanced the average success regarding the PICC insertion, particularly for the subset with a poor condition in the elbow super？cial vein. Due to the items that emerged in the PICC process, the effective prevention prior to surgery and treatment during the operation would be necessary.

Effect of Chinese herbal compound on liver fibrosis in rabbits with schistosomiasis by B-ultrasound

Objective: To explore the value of B-ultrasound on the evaluation of the effects of traditional Chinese medicine compound of Radix astragali , Salvia miltiorrhiza and Angelica sinensis , and TCM + praziquantel on liver fibrosis in rabbits with schistosomiasis. Methods: The hepatic fibrosis model in rabbits with schistosomiasis was established. The experimental animals (24 rabbits) were randomly divided into four groups (group A, B, C and D, n =6). Group A (control group) was only treated by praziquantel; Group B was treated by mixture of Radix astragali and Salvia miltiorrhiza + praziquantel; Group C was treated by mixture of Radix astragali and Angelica sinensis + praziquantel; Group D was treated by mixture of Radix astragali, Salvia miltiorrhiza and Angelica sinensis + praziquantel. Then B-ultrasonogram was used to evaluate the effects. Results: Each group showed certain curative effect on liver fibrosis in rabbits with schistosomiasis. The efficacy of group B, C and D was better than group A, and that of group D was the best. The differences in long diameter, thickness diameter, transverse diameter and portal vein inner diameter of liver before and after treatment were statistically significant ( P <0.05). The liver function indexes and liver fibrosis indexes were significantly improved after treatment ( P <0.05). Conclusions: The mixture of Radix astragali, Salvia miltiorrhiza and Angelica sinensis combined with Western medicine treatment can obviously improve the efficacy on liver fibrosis of schistosomiasis.

Analysis of B-ultrasound and contrast-enhanced ultrasound characteristics of different hepatic neuroendocrine neoplasm

BACKGROUND Hepatic neuroendocrine neoplasm(hNEN) is a highly heterogeneous tumor. The exact identification of the source and malignant degree of hNEN is important.However, there is a lack of information regarding diagnosis of hNEN with imaging. In addition, no studies have compared the imaging between hNEN and hepatocellular carcinoma(HCC) and among different sources and malignant degrees of hNEN.AIM To compare the ultrasound characteristics between hNEN and HCC and among different sources and malignant degrees of hNEN.METHODS A total of 55 patients with hNEN were recruited and defined as the hNEN group.Among them, 35 cases of hNET were defined as the hNET group. Twenty cases of hepatic neuroendocrine carcinoma(hNEC) were defined as the hNEC group.Among the 55 lesions, 29 were transferred from the pancreas, 20 were from the gastrointestinal tract, and six were from other sites. In total, 55 patients with HCC were recruited and defined as the HCC group. The characteristic differences of Bmode ultrasound and contrast-enhanced ultrasound(CEUS) between hNEN and HCC and among different sources and malignant degrees of hNEN were compared.RESULTS In the hNEN group, the proportions of multiple liver lesions, unclear borders,and high echo lesions were higher than those in the HCC group. The proportions of non-uniform echo and peripheral acoustic halo were lower than those in the HCC group(P < 0.05). The washout to iso-enhancement time and washout to hypo-enhancement time were lower than those in the HCC group(P < 0.05). The characteristics of B-ultrasound and CEUS among different sources of hNEN were similar, and the differences were not statistically significant(P > 0.05). B-mode ultrasound characteristics of hNET and hNEC were similar. The proportions of low enhancement at portal venous phase, non-uniform enhancement forms, and combined tumor vasculature in the hNEC group were larger than those in the hNEN group(P < 0.05).CONCLUSION Compared with HCC, hNEN showed multiple intrahepatic lesions, uniform high echo, uniform high enhancement at arterial phase, and rapid washout. Low enhancement at portal venous phase, overall non-uniform enhancement form,and the proportion of combined tumor vasculature in hNEC were larger than those in hNET.
