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.
ObjectiveTo investigate the value of carbon nanoparticle adopted in reoperation for thyroid cancer recurrence. MethodsFrom July to November of 2015, patients diagnosed with thyroid cancer recurrence in department of Thyroid & Parathyroid surgery, West China Hospital, Sichuan University were enrolled in the research. All enrollment patients underwent carbon nanoparticles location guided by ultrasonography before reoperation. Relative data about surgery and location were analyzed retrospectively. ResultsTwenty-two patients were enrolled in the research. Mean operation time was (60.45±12.91) minutes. During surgery, a total of 405 (average 18.4) lymph nodes were harvested, and the staining rate was 71.9% (291/405). The pathological examination showed that there was a significant difference in the positive rate between carbon nanoparticles stained lymph nodes (45.0%, 131/291) and non-stained lymph nodes (5.3%, 6/114), P < 0.001. In addition, the positive rate in non-targeted stained lymph nodes was 30.2% (62/205). By contrast, it was 5.3% (6/114) in non-targeted non-stained lymph nodes. The difference showed significant significance (P < 0.001). ConclusionsAdoption of carbon nanoparticles in reoperation for thyroid cancer, which improves efficiency of dissection for the non-palpable lymph nodes metastasis, is worth generalizing in clinical practice.
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.
Abstract： Objective To summarize surgical experiences and explore risk factors of patients undergoing repeated heart valve surgery. Methods Clinical records of 325 consecutive patients who underwent repeated heart valve surgery from January 1998 to December 2008 in Changhai Hospital of Second Military Medical University were retrospectively analyzed. There were 149 male patients and 176 female patients with their average age of （47.1±11.8） years. Following variables were collected: preoperative morbidity， heart function， indications and surgical strategies of repeated heart valve surgery， postoperative mortality and morbidity， which were compared with those clinical data of patients who underwent their first heart valve surgery during the same period. Multivariate logistic regression was used to determine risk factors of perioperative death of patients undergoing repeated heart valve surgery. Results The main reasons for repeated heart valve surgery were mitral valve restenosis after closed mitral commissurotomy and new other valvular diseases. Postoperatively， 28 patients died in the early-stage with the overall mortality of 8.6% （28/325）. The main reasons of in-hospital death included low cardiac output syndrome （LCOS）and acute renal failure. Compared with patients undergoing their first heart valve surgery， patients who underwent repeated heart valve surgery were more likely to have chronic obstructive pulmonary disease （COPD)， New York Heart Association (NYHA） classⅢ-Ⅳ， and atrial fibrillation， preoperatively. Their cardiopulmonary bypass time and aortic cross clamp time were comparatively longer. They also had more postoperative morbidities such as LCOS， acute renal failure and acute respiratory distress syndrome （ARDS）. Multivariate logistic regression showed that preoperative critical state （OR=2.82， P=0.002）， cardiopulmonary bypass time longer than 120 minutes （OR=1.13， P=0.008）， concomitant coronary artery bypass grafting （OR=1.64， P=0.005）， postoperative LCOS（OR=4.52， P＜0.001）， ARDS （OR=3.11， P＜0.001） and acute renal failure （OR=4.13， P＜0.001）were independent risk factors of perioperative death of patients undergoing repeated heart valve surgery. Conclusion Repeated heart valve surgery is a difficult surgical procedure with comparatively higher risks. Full preoperative assessment of the valvular lesions， proper timing for surgery and perioperative management are helpful to reduce postoperative mortality and morbidity.
ObjectiveTo examine the cause of failure of mitral valve repair. MethodWe retrospectively anal-yzed the clinical data of 89 consecutive patients with non-rheumatic mitral valve diseases who underwent reoperation for failure of mitral valve repair in our hospital from January 2009 through January 2016. There were 54 males and 35 females at age of 36.2±17.4 years. ResultsThere were 16 patients with reoperation of mitral valve repairs and 73 patients of mitral valve replacements. The failure reasons of initial mitral valve repair were technique-related in 63 patients (70.8%) and valve-related in 18 patients (20.2%). Technique-related causes of repair failure included leaflet suture dehiscence (20 patients, 22.5%), edge-to-edge procedure (11 patients, 12.4%), leaflet thickening or retraction (11 patients, 12.4%), ring dehiscence (8 patients, 9.0%), inappropriate annuloplasty (6 patients, 6.7%), incomplete repair (4 patients, 4.5%), and chordal elongation or rupture (3 patients, 3.4%). Median interval since previous repair was 4.0 (0.04-18.0) years for the technique-related failure group, and 9.7 (0.21-35.6) years for valve-related failure group (P < 0.05). ConclusionTechnique-related factors are main causes of repair failure, which include leaflet suture dehiscence, edge-to-edge procedure, and leaflet thickening or retraction. Reoperation for technique-related failure needs to be adopted early.
Objective To discuss the resection extent of primary surgery for papillary thyroid carcinoma （PTC） based on the analysis of the remaining thyroid gland residue and lymph nodes metastasis. Methods The clinical data of 163 patients with PTC received reoperation from January 2009 to September 2011 in our hospital were analyzed retrospectively. Results There were 24 males and 139 females in these patients. The age was 10-75 years old with （38.22±14.57） years old. Among 131 patients received residual thyroid thyroidectomy，88 patients were below 45 years old，and the cancer residual rate was 60.23% （53/88）；the others were over 45 years old，and the cancer residual rate was 76.74% （33/43），which was no significant difference （P?=?0.062）.The lymph nodes metastasis rate was 77.14% （81/105） in the patients below 45 years old and 81.13%?（43/53） in the patients over 45 years old among 158 patients received cervical lymph nodes dissection，which was no significant difference （P?=?0.958）.The cancer residual rate was 74.36%?（58/78），53.66%?（22/41），50.00%?（6/12），and 0 （0/32） in the patients with the tissue less than one lobe resection，lateral lobe （isthmus） resection，lateral lobe plus opposite side subtotal resection，total or subtotal resection，respectively. The total cancer residual rate was 65.65% （86/131） and the bilateral cancer residual rate was 52.76%?（86/163） after reoperation.79.75%?（130/163） of the patients didn’t received lymph nodes dissection in the primary surgery. The lymph nodes metastasis rate was 71.21%?（94/132） and 80.58% （83/103） in the reoperation patients received central region lymph nodes dissection and cervical lateral lymph nodes dissection, respectively. Conclusions Multifocus is an obvious character of PTC. Patients over 45 years old have more opportunities of tumor residual than that of the youngers （below 45 years old），but the result was no statistic value. For the most patients with PTC，a smaller resection extent suggests a larger risk for cancer residual，and total thyroidectomy or subtotal thyroidectomy leads to the least possibility for the risk. Cervical lymph node is a major type for its metastasis. Proper lymph nodes dissection is an essential way to reduce recurrence and reoperation. The Revised American Thyroid Association Management Guidelines for Patients with Thyroid Nodules and Differentiated Thyroid Cancer （2009） could be a best choice for therapy of PTC. And it is proposed to take central region lymph nodes dissection during primary surgery.
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.
To assess long-term outcomes of reoperation for recurrent lumbar disc herniation, and to compare results of different methods. Methods There were 95 patients who had reoperation for recurrent lumbar discherniation between February 1998 to February 2003, among whom a total of 89 (93.7%) were followed up and their primary data were reviewed. There were 76 patients, with the mean age of 42 years (range from 23 to 61), who met the inclusion criteria and were included. Among them, there were 55 males and 21 females. All patients had the history of more than one sciatic nervepain. The mean recurrent time was 69 months(range from 8 to 130 months). There were 48 patients in L4,5 and 28 patients in L5, S1, of whom we chose 30 to undergo larger vertebral plate discectomy (or two-side fenestration) and nucleus pulpose discectomy (group A), 24 to undergo the whole vertebral discectomy (group B) and 22 to undergo the whole vertebral discectomy and 360degrees intervertebral fusion(group C). The patients’ cl inical results in the three groups were compared, and the cl inical curative effects were evaluated by using cl inical functional assessment standard. Results Cl inical outcomes were excellent or good in 80.3% of the patients, including 80.0% of group A, 79.2% of group B and 81.8% of group C. There was no significant difference in each group (P gt; 0.05). These three groups were not different in age, pain-free interval and follow-up duration (P gt; 0.05). The mean intraoperative blood losses in the three groups were (110.7 ± 98.8), (278.7 ± 256.3), (350.7 ± 206.1) mL, respectively. The mean surgery time were (65.9 ± 22.8), (111.6 ± 24.3), (127.3 ± 26.7) minutes, respectively, and the mean hospital ization time were (6.7 ± 1.4), (10.2 ± 1.8), (12.2 ± 2.3) days, respectively. Group A was significantly less than group B or C (P lt; 0.05) and there was no significant difference between group B and C. All the patients were followed up for 36 to 96 months with an average of 86 months, and with (87.6 ± 27.0), (84.5 ± 19.8), (83.6 ± 13.5) months of group A, B and C, respectively. At the endof the follow-up, there were more cases of spinal instabil ity at the same level in group B (19 patients) than in group A (1 patient) or group C (no patient) in X-ray, and the difference was significant (P lt; 0.05). Conclusion Reoperation for recurrent lumbar disc herniation is effective. Larger vertebral plate discectomy or tow-side fenestration is recommended for managing recurrent lumbar disc herniation.
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.
Objective To explore the reoperative techniques of differentiated thyroid carcinoma. Methods Clinical data of 56 patients who treated in The First Affiliated Hospital of General Hospital of PLA and General Hospital of PLA from Feb. 2011 to Feb. 2013 were analyzed retrospectively. Results All performed surgeries were successful. Surgeries took 90-150 minutes with an average of 120 minutes. Bleeding during surgeries was 70-200 mL with an average of 120 mL. Postoperative drainage was 90-210 mL with an average of 100 mL. The pathological diagnosis of the second surgery in 44 cases were as the same as the first， but there were no malignant tumor tissues of dissected glands in 12 cases. All patients had no postoperative bleeding and bucking， but 8 patients experienced hand and foot numbness， and 5 patientsexperienced transient hoarseness. Fifty patients were followed-up for 6-30 months （average 10.8 months） from the reoper-taion and 18-66 months （average 45.2 months） from the first operation， and rate of postoperative followed-up was 89.3%（50/56）. During the followed-up， 1 patient with papillary thyroid carcinoma and 1 patient with follicular thyroid carcinoma died in 44 months and 38 months respectively， 3 patients suffered lymph node metastasis at non-Ⅵ region ofaffected side， no one suffered recurrence. Conclusions For differentiated thyroid carcinoma patients who are undergoingthe second surgery， thorough whole body condition analysis should be performed and appropriate type of surgery should be chosen. By using recurrent laryngeal nerve monitoring， carbon nanoparticles for lymph node clearance， and protecting parathyroid gland to lower the possibility of postoperative complication， to improve survival rate and life quality.
