ABSTRACT
Objective:To summarize the clinical characteristics of patients with unicentric Castleman disease(UCD).Method:The clinical data of 8 abdominal UCD patients who received surgical resection at the Second Hospital of Hebei Medical University from Oct 2019 to Oct 2022 were analyzed, and the imaging characteristics, pathological types and prognosis were summarized.Result:There were 2 males and 6 females. The average age of patients was (33.0±13.7) years old, and their BMI was (23.2±4.5) kg/m 2. The median maximum diameter of the tumor was 4.5 (3.0-4.9) cm. The average postoperative hospital stay was 6.5 (3.3-12.0) days. One was lost during follow up, there was no recurrence or other postoperative complications in the remaining 7 patients. Conclusion:The incidence of unicentric Castleman disease is rare. Complete resection of the tumor is the main treatment for UCD patients, and the prognosis of UCD is good.
ABSTRACT
Objective:To evaluate and analyze the ultrasonic findings of idiopathic clubfoot and positional clubfoot deformities.Methods:Forty-nine newborn babies with congenital clubfoot were examined in the Department of Ultrasound of the Third Affiliated Hospital of Zhengzhou University from December 2020 to January 2022, Including 21 newborn babies(32 feet) with idiopathic clubfoot, and 28 babies(53 feet) with positional clubfoot. Twenty-two normal infants in the same period and the normal feet of the single clubfoot were selected as control group. The distance between medial malleolus and scaphoids of all feet were measured by ultrasound. The distance from the tangent line of the lateral edge of calcaneus to the midpoint of the lateral edge of the chondroid bone, medial soft tissue thickness and tibial calcaneal angle were measured by ultrasound. The data of idiopathic clubfoot group, positional clubfoot group and control group were statistically analyzed.Results:A total of 71 newborn babies with 142 feet were evaluated.The idiopathic clubfoot group had born and joint changes in the medial, lateral and posterior side, and the differences were statistically significant compared with the control group (all P<0.05). Compared with the control group, there were statistically significant differences in the medial and lateral side of the positional group(all P<0.05). But no significant changes in the posterior side( P>0.05). There were significant differences between medial and posterior side of idiopathic and positional clubfoot group (all P<0.05), but no significant differences in lateral side ( P>0.05). Conclusions:Ultrasonography can clearly display the tarsus bones in clubfoot, and observe the deformity changes of the idiopathic clubfoot and positional clubfoot.
ABSTRACT
Objective:To explore the clinical efficacy and safety of single-layer with full thickness of duct-to-mucosa pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.Methods:The clinical data of 45 patients who underwent laparoscopic pancreaticoduodenectomy with the procedures of single-layer with full thickness in Second Hospital of Hebei Medical University from Jan 2020 to Jan 2022 were retrospectively collected and compared with 45 matched patients with traditional two-layer pancreaticojejunostomy.Results:The laparoscopic pancreaticoduodenectomy procedures were successfully performed in all the 90 cases. The mean operation time (285.6±92.4 minutes) and the media pancreaticojejunostomy time 20(15, 35) minutes) of the single-layer with full thickness pancreaticojejunostomy group were shorter than those of the two-layer pancreaticojejunostomy group [the mean operation time: 317.0±85.5 minutes, the media pancreaticojejunostomy time: 46(30, 58) minutes] with significantly statistical differences (all P value<0.05). There were no significantly statistical differences on intraoperative blood loss, the postoperative complications or hospital stay between the two groups. Conclusions:Compared with traditional pancreaticojejunostomy, the single-layer with full thickness of duct-to-mucosa pancreaticojejunostomy is simple and safe, which has the advantage of easy manipulation and less time-consuming and can be recommended for laparoscopic procedures.
ABSTRACT
The incidence of portal vein tumor thrombus (PVTT) in patients with hepato-cellular carcinoma (HCC) is high and the prognosis is poor. The treatment mode of HCC+PVTT is changing to multidisciplinary comprehensive treatment. The authors make a deep investigation on the occurrence basis, classification, surgical treatment indication, postoperative adjuvant treatment and preoperative conversion treatment plan of HCC+PVTT, in order to provide reference for the diagnosis and treatment of this disease.
ABSTRACT
Objective:To investigate the application value of three dimensional (3D) imaging fusion navigation system (hereinafter referred as navigation system) in laparoscopic pan-creatic surgery.Methods:The retrospective and descriptive study was conducted. The clinical data of two volunteers, including volunteer 1 undergoing laparoscopic pancreaticoduodenectomy for cholangiocarcinoma and volunteer 2 undergoing laparoscopic pancreaticotomy + splenectomy for pancreatic cancer, who were admitted to the Second Hospital of Hebei Medical University from December 2020 to May 2021 were collected. The 2 volunteers were females, aged 68 years and 40 years, respectively. The self-developed navigation system was applied in laparoscopic simulator model test, including in rigid-body model and prosthesis model, and clinical test. Observation indicators: (1) results of model test; (2) results of clinical test. Measurement data with normal distribution were represented as Mean± SD. Results:(1) Results of model test. The rigid-body model or prosthesis model with occlusion can be seen in the laparoscopic visual field of the initial laparoscopic simulator. The rigid-body model or prosthesis model with occlusion and rigid-body model or prosthesis model without occlusion can be seen in the 3D visual reconstruction image of enhanced computer tomography (CT) examination. The rigid-body model or prosthesis model with occlusion can be seen in the laparoscopic visual field of the initial laparoscopic simulator after the 3D visual reconstruction image was superimposed and fused with the real-time laparoscopic image. Both of the rigid-body model and prosthesis model were in high consistency, with the distance error of marker points were (0.26±0.11)mm and (0.29±0.18)mm, respectively. (2) Results of clinical test. The abdominal organs and blood vessels with occlusion of the 2 volunteers can be seen in the initial laparoscopic visual field. The location of tumor, important organs and blood vessels can be seen in the navigation system using the 3D visual reconstruction image of enhanced CT examination. The location of tumor, important organs and important blood vessels can be seen in the laparoscopic visual field after the 3D visual reconstruction image was superimposed and fused with the real-time laparoscopic image. The distance error of marker points of the volunteer 1 was (1.36±0.57)mm and the distance error of marker points of the volunteer 2 was (1.24±0.33)mm.Conclusions:The self-developed navigation system can integrate the preoperative 3D visual reconstruction image of enhanced CT examination and the intraoperative real-time laparoscopic image with a good effect. The relationship between deep tissue and blood vessels which is not clarified in conventional laparoscopy can be shown in the navigation system assisted laparoscopic pancreatic surgery.
ABSTRACT
Objective:To compare and analyze the perioperative outcomes of jaundiced patients undergoing laparoscopic pancreaticoduodenectomy (LPD) using preoperative percutaneous transhepatic cholangial drainage (PTCD) versus endoscopic nasobiliary drainage (ENBD).Methods:The perioperative data of 173 patients who underwent LPD at the Second Hospital of Hebei Medical University from January 2016 to December 2020 and were treated preoperatively with either PTCD versus ENBD to alleviate jaundiced were retrospectively analyzed. There were 100 males and 73 females, with age of (60.4±10.8) years old. These patients were divided into the PTCD group ( n=126) and the ENBD group ( n=47). Clinical data including operation time, blood loss, transfusion volume, R 0 resection, and postoperative complications were compared. Results:There was no convension to open surgery. There were no significant differences in operation time, blood loss, transfusion volume, R 0 resection rate, pathological results and hospital stay between the two groups ( P>0.05). For the PTCD group, the pancreatic fistula rate was 10.3% (13/126) and the post-operative hemorrhage rate was 8.7% (11/126). They were both significantly lower than those of the ENBD group [25.5% (12/47) and 25.5% (12/47) respectively, P<0.05]. There were also significant differences in the postoperative complications according to the Clavien-Dindo classification system between the two groups ( P=0.008). Conclusion:Compared with ENBD, PTCD had the advantages of lower post-operative pancreatic fistula and post-operative hemorrhage rates, resulting in a better postoperative recovery.
ABSTRACT
Objective:To study the factors related to development of pancreatic fistula after laparoscopic distal pancreatectomy.Methods:The clinical data of all patients who underwent laparoscopic distal pancreatectomy at the Second Hospital of Hebei Medical University from January 2019 to December 2020 were retrospectively analyzed. Gender, age, intraoperative blood loss, treatment of pancreatic stump, body mass index (BMI), pancreatic texture, albumin and other indicators were analyzed between patients with and without pancreatic fistula. Logistic regression analysis was used to determine independent risk factors for pancreatic fistula.Results:Of 93 patients in this study, there were 33 males and 60 females, mean age (49.23±15.62), range 16 to 76 years. The incidence of postoperative pancreatic fistula was 34.4% (32/93). On univariate analysis, BMI (χ 2=4.515, P=0.034), pancreatic texture (χ 2=3.891, P=0.049), preoperative serum albumin ( t=2.644, P=0.010) and albumin difference ( t=-2.293, P=0.024) were significantly associated with postoperative pancreatic fistula. Multivariate logistic regression analysis showed that low preoperative albumin ( OR=0.551, P<0.001), large difference in albumin ( OR=1.542, P<0.001), BMI≥25 kg/m 2 ( OR=3.303, P=0.035) and soft pancreatic texture ( OR=3.065, P=0.049) were independent risk factors for pancreatic fistula. Conclusion:For patients with BMI≥25 kg/m 2 and patients with a soft pancreas, there was a higher chance to develop pancreatic fistula after operation.
