ObjectiveTo explore the value of laparoscopic choledocholithotomy on hepatolithiasis patients with previous bile duct surgery contraindicating hepatectomy. MethodsEighty-six hepatolithiasis patients contraindicating hepatectomy accepted laparoscopic choledocholithotomy during March 2009 and March 2013 in the department of general surgery, AVIC 363 hospital. Among them, 26 cases with previous bile duct surgery(PBS group) and 60 cases without (NPBS group), 15 cases with left intrahepatic bile duct stone, 52 cases with right intrahepatic bile duct stone, and 19 cases with bilateral intrahepatic bile duct stone. Perioperative materials were reviewed between two groups retrospectively. ResultsThe operation time of the PBS group and NPBS group was(161.4±31.5) min and(155.7±28.1) min respectively(P > 0.05). And the intraoperative blood loss of them was(69.2±50.7) mL and(44.1±27.4) mL respectively (P < 0.05). Postoperative complication incidence of PBS group was 53.8%, among them, ascites was found obviously much more in PBS group than that in NPBS group(P < 0.05). The general residual stone incidence of two groups was 15.1%, and the general stone clearance rate was 98.8%. The long term postoperative complication occurrence in PBS group was 23.1%, which was higher significantly than that in NPBS group(P<0.05). ConclusionLaparoscopic choledocholithotomy is a safe, effective thus feasible choice for hepatolithiasis patients with previous bile duct surgery, especially for those without hepatic atrophy, bilateral hepatic bile ducts stone with hepatic bile duct stricture and hepatic bile duct stone with coexisting biliary cirrhosis.

Objective To analyze the causes and the reoperation therapies after salvage limb surgery with prosthesis for bone tumors. Methods The retrospective analysis was performed on 85 patients undergoing the limb salvage operation with prosthetic replacement for tumors from January 1994 to December 2004. Ofthe patients, 21 (13 males and 8 females, aged 18-58 years) underwent reoperations for various reasons. All the diagnoses were pathologically confirmed(10 patients with osteosarcoma, 4 with chondrosarcoma, 5 with giant cell tumor of the bone, 2 with osteofibrosarcoma). The distal femur was involved in 9 patients, proximal tibia in 8, proximal femur in 2, proximal humerus in 1, and acetabulum in 1. According to the Enneking surgical grading system, there were 5 patients in ⅠB and 16 in ⅡB. The time between the first operation and the reoperation was 2 weeks to 20 years. The common reasons for the reoperation were tumor recurrence in 8 patients, prosthetic loosening in 5, no healing of the incision in4,joint dislocation in 3, and implant fracture in 1. The amputation and the prosthesis revision were respectively performed on 6 patients, extensive resection ofthe tumor on 3, the myo-skin flap translocation on 4, internal hemipelvectomy without reconstruction on 1, and open reduction on 1.Results The follow-up in18 patients for 1-5 years (average, 3 years and 4 months) revealed that 4 patients died of osteosarcoma with pulmonary metastasis. The other 14 patients had no tumor recurrence or loosening of the prosthesis, and the incisions healed well. The assessment on the joint function was performed on 13 of the 18 patients and the results were as follows: excellent in 2 patients, good in 5, fair in 4, and poor in 2, with a satisfaction rate of the reoperation with limb salvage of 84.6%and an excellent-good rate of 53.8%. Conclusion Tumor recurrence is the most common reason for the reoperation after the limb salvage with prosthesis for tumors, and loosening of the prosthesis is an important reason, too. By therules of the bone tumor limb savage, the limb salvage operations can also beperformed, which can achieve a satisfactory result of the limb function.
ObjectiveTo analyze the reasons for the failure of scleral buckling (SB) in the treatment of rhegmatogenous retinal detachment, and observe the efficacy and safety of re-buckling.MethodsThis was a retrospective non-comparative clinical research. From July 2014 to June 2020, patients with first-time SB failure who visited the Beijing Tongren Hospital were included in this study. There were 42 patients, including 30 males and 12 females, with the average age of 29.40±16.13 years, and they were all monocular. The retinal detachment range＜1, 1-2 and＞2 quadrants were 9, 22 and 11 eyes, respectively. The macula was involved in 38 eyes. The average logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity (BCVA) was 0.99±0.57. Forty eyes and 2 eyes were performed 1 and 2 SB, and all the retina were not reattached. All patients were under general anesthesia, according to the conditions during the operation, re-freeze and located the holes under indirect ophthalmoscope. And selected the new external pressure material or retained the old one in combination with the other operations to reattaced the retina. The average follow-up time was 31.93±18.97 months. The reasons for the failure of the first surgery based on the records of this surgery were analyzed. The visual acuity changes, the rate of retinal reattachment and the occurrence of complications were observed. The visual changes were compared by paired t test.ResultsThe top three reasons for the failure were: 16 case of the displacement of the compression spine (38.10%); 9 cases of missing the retinal holes and 9 case of improper selection of compression substances (account for 21.43%, respectively); 6 cases of insufficient height of compression spine (14.29%). All of retina were reattached (100%, 42/42). The average logMAR BCVA was 0.52±0.40. The difference of logMAR BCVA between before and after surgery was statistically significant (t=6.106, P=0.000). There were a slight increase in intraocular pressure in 8 eyes, the average intraocular pressure was 25.00±2.61 mmHg (1 mmHg=0.133 kPa). No serious complications occurred after surgery.ConclusionsThe position deviation of the compression spine, the missed hole during the operation, the improper selection of external compression material, and the insufficient height of the compression spine are the main reasons for the failure of SB. After adjusting the reasons for the failure, there is still a higher rate of retinal reattachment.

ObjectiveTo discuss outcomes of arch reintervention for post-repair recoarctation in children.MethodsFrom 2009 to 2019, 48 patients underwent reintervention for post-repair recoarctation in Shanghai Children’s Medical Center. Of the 48 patients, 22 patients had surgical repair, 25 patients had balloon angioplasty (BA), and 1 patient had a stent implantation. The clinical data were analyzed, and the difference in time-to-event distribution between the surgical group and the BA group was determined by a log-rank test.ResultsThe median age at reintervention was 15.0 months (range, 3.0 months-15.1 years). The median weight at reintervention was 9.8 kg (range, 3.0-58.0 kg). The time to reintervention after initial repair was 12.5 months (range, 2.0 months-7.8 years). One patient (2.1%) died in hospital and 1 patient (2.1%) experienced arrhythmia after surgical repair. One late mortality (2.1%) occurred after surgical reintervention. One patient (2.1%) experienced aortic dissection after BA. No patient died after BA. Freedom from residual coarctation or new recurrences was 66.7%, 61.3%, and 56.9%, respectively, at 1, 2, and 5 years after reintervention. Freedom from residual coarctation or new recurrences was 90.0%, 81.8%, and 70.1%, respectively, at 1, 2, and 5 years after surgical repair. Freedom from residual coarctation or new recurrences was 52.0%, 48.0%, and 48.0%, respectively, at 1, 2, and 5 years after BA. Compared with BA, surgery-based reintervention had a lower incidence of residual coarctation or recurrences (χ2=4.400, P=0.036).ConclusionReintervention for recoarctation has favorable early outcomes. Compared with balloon angioplasty, surgical repair has a more lasting effect in relieving the recoarctation.
Objective To investigate the efficacy of leaflet augmentation technique to repair the recurrent mitral valve (MV) regurgitation after mitral repair in children. Methods A retrospective analysis was conducted on the clinical data of children who underwent redo MV repair for recurrent regurgitation after initial MV repair, using a leaflet augmentation technique combined with a standardized repair strategy at Fuwai Hospital, Chinese Academy of Medical Sciences, from 2018 to 2022. The pathological features of the MV, key intraoperative procedures, and short- to mid-term follow-up outcomes were analyzed. Results A total of 24 patients (12 male, 12 female) were included, with a median age of 37.6 (range, 16.5–120.0) months. The mean interval from the initial surgery was (24.9±17.0) months. All children had severe mitral regurgitation preoperatively. The cardiopulmonary bypass time was (150.1±49.5) min, and the aortic cross-clamp time was (94.0±24.2) min. There were no early postoperative deaths. During a mean follow-up of (20.3±9.1) months, 3 (12.5%) patients developed moderate or severe mitral regurgitation (2 severe, 1 moderate). One (4.2%) patient died during follow-up, and one (4.2%) patient underwent a second MV reoperation. The left ventricular end-diastolic diameter was significantly reduced postoperatively compared to preoperatively [ (43.5±8.6) mm vs. (35.8±7.8)mm, P<0.001]. Conclusion The leaflet augmentation technique combined with a standardized repair strategy can achieve satisfactory short- to mid-term outcomes for the redo mitral repair after previous MV repair. It can be considered a safe and feasible technical option for cases with complex valvular lesions and severe pathological changes.
This paper reports twelve patients underwent repeat hepatic resection because of the recurrence of hepatocellular carcinomas after primary resection. The indication of reoperation, selection of incision, difficults encountered in the operation and the treatment after operation are discussed. The authors believe that the second operation is technically more difficult than the first one, some troubles my be happened during the operation and put forward some ways to deal with this situations.
