ABSTRACT
Objective:To explore the feasibility, efficacy and limitation of robot-assisted laparoscopic surgery in the treatment of adrenal tumors in children.Methods:The clinical data of 5 children with adrenal tumors treated with robot-assisted laparoscopic surgery in Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science & Technology from October 2020 to March 2021 were retrospectively analyzed. All patients were males aged between 2 years and 4 months to 13 years and 1 month (median: 7 years and 7 months). One case had left adrenal adenomas and 4 cases had right adrenal adenomas.The maximum diameter of tumors was 3.0-6.0 cm (median: 4.8 cm).Results:Robot-assisted laparoscopic adrenalectomy was performed successfully on all 5 patients.The ope-ration time was 215-325 min (median: 275 min). The intraoperative bleeding was 10-50 mL (median: 28 mL). The indwelling time of the drainage tube after surgery was 3-5 days (median: 4 days). The postoperative hospital stay was 9-13 days (median: 11 days). The hospitalization cost was 51 268-58 157 yuan (median: 53 485 yuan). No complications occurred during or after the operation.Postoperative pathological tests suggested adrenal cortex adenocarcinoma in 1 case, pheochromocytoma in 1 case, gangliocytoma in 2 cases, and ganglioneuroblastoma in 1 case.Conclusions:Robot-assisted laparoscopic surgery is safe and feasible in children with adrenal tumors, but there are some limitations.This approach needs to be verified by further clinical research.
ABSTRACT
Objective To investigate the imaging characteristics of renal cell carcinoma associated with Xp11.2 translocation/TFE3 gene fusion. Methods We retrospectively analyzed the clinical and imaging data of five children with Xp11.2 tRCC confirmed by surgery and pathology in our hospital from January 2015 to December 2020. Four cases underwent CT plain scan and contrast-enhanced examination, and one case underwent MRI plain scan, contrast-enhanced examination and DWI examination. We observed and analyzed the location, size, shape, boundary, composition, enhancement pattern and degree, the relation with the renal hilum and adjacent large vessels, and the metastasis of the tumor. Results All cases were cortical-medullary type. Four cases were solid/cystic-solid lesions, iso- or slightly hyper-density on CT scans with calcification and necrosis, in which a few with bleeding or cystic lesions. Enhanced scanning primarily showed mild to moderate enhancement, and enhancement of pseudocapsule was seen during the delayed phase. One case was cystic lesion, the cystic fluid presented as hypo-density on CT, and T1 hypo-intensity and T2 hyper-intensity, as well as restricted diffusion on DWI. No enhancement was found in the cystic part after enhancement. There were irregular and thickened cystic wall and septum, and mural nodules on enhanced MRI. Conclusion Several characteristics of Xp11.2 tRCC in children could be drawn. Punctate and patchy calcifications in or around the solid/cystic-solid lesions and delayed "pseudocapsule sign" are typical. The possibility of Xp11.2 tRCC should be considered when there are irregular and thickened cystic wall and septum and the enhancement of mural nodules.
ABSTRACT
Liver injuries are the most common pediatric blunt abdominal injury, which is also the leading cause of trauma death in children.Currently, the severity of liver injuries has been universally classified according to criteria proposed by the American Association for the Surgery of Trauma (AAST). Within the past three decades, the management of liver injuries has evolved from obligatory operation to non-operative management in over 90% of cases.Moreover, the diagnosis and treatment of liver injuries in children is slightly different from that of adults because of special physiological and anatomical characteristics of children.Based on the World Society of Emergency Surgery (WSES) guidelines on the diagnosis and treatment of liver injuries, this study reviewed the development of children′s liver injuries, current diagnosis and treatment prospects and long-term treatment results in the combination with the physiological characteristics of children′s liver, aiming to improve the diagnosis and treatment, reduce mortality and complications of liver injuries in children.
ABSTRACT
Objective To study the use of laparoscopy in the diagnosis and treatment of obstructive infantile cholestasis.Methods The clinical data of 106 patients with obstructive infantile cholestasis from January 2012 to June 2017 were studied retrospectively.After two weeks of conservative treatments which failed to decrease the bilirubin levels significantly,these patients were subjected to laparoscopic diagnosis and treatment.Results A correct diagnosis was established in all these 106 patients by laparoscopic biliary tract exploration and cholangiography.Eighty-eight patients were diagnosed to have biliary atresia (83.0％),16 patients inspissated bile syndrome (15.1％) and 2 patients biliary hypoplasia (1.9％).Thirty-eight of the 88 biliary atresia patients gave up operative treatment after laparoscopic biliary tract exploration and cholangiography.The remaining 50 biliary atresia patients were treated with open Kasai portoenterostomy.The prognosis of the biliary atresia patients were different from the non-biliary atresia patients.On follow-up for 4 months to 5 years,all the 18 non-biliary atresia patients were in good condition and there was no recurrence of jaundice after laparoscopic cholecystostomy and biliary tract irrigation.Conclusions The laparoscopic minimally invasive technique helped to establish diagnosis and treatment in patients with obstructive infantile cholestasis.For patients with biliary atresia,this procedure gave a definitive diagnosis and offered an opportunity for surgery.For patients with inspissated bile syndrome and biliary hypoplasia patients,laparoscopic cholecystostomy and biliary tract irrigation established the correct diagnosis and reduced liver damage resulted by cholestasis.
ABSTRACT
Objective To explore the value of laparoscopy in the diagnosis and treatment of recurrent inguinal hernia in children.Methods The clinical data of 67 cases receiving laparoscopic treatment for recurrent inguinal hernia in children at the Department of General Surgery,Wuhan Children's Hospital,Tongji Medical College,Huazhong University of Science & Technology were retrospectively analyzed,including the type of hernia recurrence,operation time,intraoperative and postoperative complications,such as short-term hydrocele formation and testicular atrophy and so on.Results In 67 cases,there were 65 males and 2 females.Open repair surgery and laparoscopic surgery were respectively performed in 48 cases and 19 cases for the first operation and the hernia defects were found after operation.Contralateral patent vaginal process deformities were found in 11 sides in the reoperation.Among 67 cases of recurrent inguinal hernia,incomplete ligation of hernia sac was found in 21 cases,low level ligation of hernia sac in 17 cases,no ligation of hernia sac in 14 cases,omissive direct inguinal hernia in 4 cases,loose ligation of hernia sac in 4 cases,overlarge inner ring in 4 cases,weak abdominal muscles in 2 cases,and increased abdominal pressure (long-term constipation,asthma) in 1 case.All the patients were treated by laparoscopic hernia repair and no serious complications occurred during the operation.The average time of unilateral operation was (15.0±2.2) minutes (13-25 minutes),and bilateral operation was (27.0±4.3) minutes (18-41 minutes).All patients were discharged on the second day.Two patients showed short-term postoperative hydrocele and were cured with conservative treatment.During the follow-up time of (23±2) months (9-39 months),no recurrence or testicular atrophy was found.Conclusions Laparoscopy can confirm the type of recurrent inguinal hernia and contribute to reduce postoperative recurrence.Laparoscopic management of recurrent inguinal hernia in children is safe and feasible,which is expected to replace open hernia repair.
ABSTRACT
Objective To explore the etiology,clinical characteristics,diagnosis and treatment of the bile duct perforation in children.Methods The clinical data of 7 children with the bile duct perforation were retrospectively summarized in Wuhan Children's Hospital from April of 2009 to April of 2014.Results There were 7 cases of the children with perforation of the bile duct,1 male and 6 female,the average age was 2.05 years.The most common presenting symptoms were abdominal distension in 7 cases(100.0％),nausea and vomiting in 6 cases(85.7％),abdominal pain in 5 cases(71.4％),jaundice in 1 case(14.3％) and diarrhea in 1 case(14.3％).Six cases experienced preoperative abdominal paracentesis,which all gained bilious ascites.Both abdominal ultrasound and computed tomography(CT) showed ascites in 5 cases.On exploration,sites of perforation were seen in 3 cases(42.8％) at the junction of the common hepatic duct and cystic duct,1 case(14.3％) at common hepatic duct,and 1 case(14.3％) at common bile duct,while sites of perforation in other 2 cases(28.6％) were not localized.In the cases(case 1,2,5 and 7) whose site of perforation was large,the T-tube drainage and peritoneal drainage through laparotomy or laparoscopic surgery was performed.In case 4 whose site of perforation was very small,and case 3 and 6 whose site of perforation was not localized,the cholysystostomy and peritoneal drainage was performed through laparotomy or laparoscopic surgery.Simple closure of the perforation was performed in case 4.Case 4 and 5 showed recurrent abdominal pain after operation and abdominal CT revealed biliary tract dilatation,and then biliary reconstruction was performed.Both of the patients recovered well postoperatively.The other 5 children recovered well and had an uneventful postoperative period from the 7 months to 5 years follow-up.Conclusions Early diagnosis of perforation of the bile duct can be made based on clinical manifestations,abdominal ultrasound and CT and abdominal paracentesis.Active surgical treatment should be performed once diagnosis was made.Depending on the size of perforation of the bile duct,appropriate surgical drainage scheme is made.The children with recurrent abdominal pain and biliary tract dilatation should receive biliary reconstruction.
ABSTRACT
Gastrointestinal bleeding is common in children. The causes of hemorrhage is numer-ous and varies with age. Most of them can be identified by conventional endoscopy and imaging examina-tion. For unexplained bleeding,especially repeated bleeding which failed to conservative therapy,a one-stop hybrid procedure of gastrduodenoscopy,colonoscopy and laparoscopy showed great clinical application value. Endoscopic hematischesis is widely used for minimally invasiveness,effectiveness,and recognition of biopsied lesions. With the progress of laparoscopic technology,single-port transumbilical laparoscopy is increasingly applied in pediatric gastrointestinal bleeding. While surgical exploration is still mandatory for massive hemorrhage in emergency circumstances.
ABSTRACT
Objective To explore the feasibility and effect of laparoscopic Ladd's surgery for the treatment of intestinal malrotation in infants.Methods The clinical data of 50 infants with intestinal malrotation who were admitted to the Wuhan Medical & Health Center for Women and Children from January 2011 to December 2013 were retrospectively analyzed.Of 50 infants, 27 infants receiving the open Ladd's surgery were allocated into the open surgery group and 23 infants receiving the laparoscopic Ladd's surgery were allocated into the laparoscopy group.The operation time, time to anal exsufflation, duration of hospital stay, postoperative incision infection and intestinal obstruction in the 2 groups were observed.All the patients were followed up by outpatient examination or telephone interview till March 2014.The measurement data with normal distribution were presented as x-± s and analyzed by the t test, and count data were analyzed using the chi-square test or Fisher exact probability.Results The operation time, time to anal exsufflation and duration of hospital stay were (69 ± 7)minutes, (41 ±9)hours and (10.4 ± 2.4)days in the open surgery group, which was significantly different from (92 ± 13)minutes, (28 ±5)hours and (6.4 ± 1.5) days in the laparoscopy group (t =6.21, 16.50, 6.34,P ＜ 0.05).Two infants had incision infection and 1 infant had intestinal obstruction in the open surgery group.There was no patient with complications in the laparoscopy group.All the patients were followed up for the median time of 13 months (range, 6-24 months), with a good survival and no other symptoms.Conclusion Laparoscopic Ladd's surgery is safe and feasible compared with open surgery, and it could be used as a prior operation method for treatment of intestinal malrotation in infants.
ABSTRACT
Objective To investigate the clinical features of pedistric Littre hernia.Methods Clinical data of 11 cases of Littre hermia admitted from January 2002 to December 2010 was studied retrospectively.Results The diagnosis of Littre hernia was all established by laparotomy.All of the 11 cases were boys,the median age was 1.2 years (22 days to 3 years and 7 months).The main clinical features were:painful,irregular and nonresetable mass in the groin area (11/11),vomiting in 6 cases (6/11 ),fever (＞38.5 ℃ ) in 4 cases (4/11 );X-ray showed intestinal obstruction in 9 cases (9/11 ),Ultrasound found mixed mass in the groin area in 11 cases ( 11/11 ),pouch-like structure were found in 6 cases (6/11).Eight cases (8/11) presented with elevated WBC ( ＞ 10000).Palpable lobulated structure were fell in 5 cases (5/11).All cases of Littre hernia were successfully operated on,Meckel diverticulum perforation was found in 2 cases ( 2/11 ),Meckel diverticulum adhered to the hernia sac in 8 eases (8/11).All patients were cured by surgery,and postoperative follow-up (10ms-8y) found no recurrence.Conclusions Pediatric Littre hernia is rare,preoperative diagnosis is difficult.Avoiding preoperative violent reduction and intraoperative injuring Meekel's diverticulum or the small bowel helps improve the cure rate of Littre hernia in children.
