Staged operation in the surgical treatment of granulomatous lobular mastitis.

Background: Granulomatous lobular mastitis (GLM) is a chronic inflammatory breast condition characterized by an unclear etiology and an undefined therapeutic approach. Surgical intervention is considered an alternative modality for managing GLM. Staged operation is the predominant and characteristic surgical approach in the treatment of GLM in our center; therefore, we evaluated the efficacy of staged operative techniques in this cohort study. Methods: We retrospectively reviewed 212 patients with GLM who underwent staged operation between August 2020 and July 2022 in the inpatient department of our institute. Their clinical history information, clinic complaints, treatment details, surgical outcomes, follow-up results, and scores on the satisfaction questionnaire were analyzed. The patients were called for follow-up and consultation with a deadline of August 2023. Results: The median follow-up time was 27 months (range, 14-37 months). In total, 212 patients were treated with three different staged procedures according to the individual assessment and patient willingness, including 168 patients who underwent one-stage debridement operation and two-stage suture operation (DO + SO), 25 patients who underwent one-stage debridement operation without suture (DO), and 19 patients who underwent one-stage debridement and simultaneous suture operation (DSO). The median recovery time was 29 days (range, 14-60 days). A minority of patients developed postoperative complications, including effusion (1.89%), flap ischemia (0.94%), areola-nipple ischemia (0.94%) and sinus tract formation (2.36%). The scores of the satisfaction questionnaire were 43.10±3.09, and 186 patients (87.74%) gave high scores for postoperative breast appearance. Only 5 of 212 patients (2.36%) developed recurrence. Conclusions: Staged operation performed in our institute is an effective and safe surgical therapy in patients with GLM, yielding a short recovery time, low recurrence and good cosmetic results.

Risk Factors and Exit Strategy of Intraoperative Neurophysiological Monitoring Alert During Deformity Correction for Adolescent Idiopathic Scoliosis.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To elucidate the risk factors of intraoperative neurophysiological monitoring (IONM) alert during deformity correction surgery for adolescent idiopathic scoliosis (AIS) and to describe the outcomes of patients who underwent staged correction surgery due to IONM alert during the initial procedure. METHODS: We reviewed 1 024 patients with idiopathic scoliosis who underwent deformity correction and were followed-up for ≥1 year. The pre-and postoperative Cobb angle of the major structural curve, operative time, estimated blood loss (EBL), number of levels fused, event that caused the IONM alert, and intervention required for the recovery of the signal were recorded. Patients who received IONM alerts (alert group) and those who did not (non-alert group) during the operation were compared. RESULTS: Compared to the non-alert group, the alert group had a significantly greater preoperative Cobb angle of the major structural curve (P < .001), number of levels fused (P = .003), operative time (P < .001), and EBL (P < .001). The percentage of correction did not significantly differ between the 2 groups (P = .348). Eight patients (.8%) underwent a staged operation because the IONM signal alert hindered correction of the deformity. The percentage of correction of patients who underwent staged operation was 64.9 ± 15.1%, and no permanent neurologic deficits occurred. CONCLUSIONS: A greater magnitude of preoperative deformity and surgical extent increases the risk of cord injury identified by IONM alerts during correction of deformities in patients with AIS. However, in patients in whom the IONM alert cannot be recovered or reproduced by proceeding with deformity correction, surgeons can minimize the risk by aborting the initial procedure and completing the correction using staged operations.

Staged operations for a hypervascular mixed germ cell tumor with growing teratoma syndrome: a case report.

INTRODUCTION: A mixed germ cell tumor with a teratoma component can become enlarged following chemotherapy, and such an event is diagnosed as growing teratoma syndrome. Removing large, hypervascular tumors including a tumor encased by developed vasculatures from the pineal region is challenging during a single operation. CASE REPORT: A 15-year-old male underwent chemotherapy for mixed germ cell tumors according to the KSPNO G082 protocol. This case of a mixed germ cell tumor with growing teratoma syndrome was recognized very early during chemotherapy. The tumor was completely removed during the staged operations. First, the anteriorly located tumor on the third ventricle was removed via the transcallosal interforniceal approach, and 1 month later, the occipital transtentorial approach was used for the pineal tumor with decreased vascularity. CONCLUSION: Performing staged operations could be recommended for large hypervascular pineal tumors, which can be safely removed during the second operation once vascularity has decreased.

A Staged Operation as a Surgical Strategy for a Patient with Type VI Isolated Superior Mesenteric Artery Dissection.

An isolated superior mesenteric artery (SMA) dissection (ISMAD) is extremely rare among visceral artery dissections. Its diagnosis is made by abdominal contrast CT scan which shows SMA occlusion partially or completely. The ISMAD is classified into 6 types: type I-V has partial occlusion and treated medically using antiplatelets or anticoagulants. On the other hand, type VI has complete occlusion and must be treated by urgent surgical operation. We present a 67-year-old female who presented with sudden onset abdominal pain and melena. An urgent contrast CT revealed type VI ISMAD. She underwent 3 staged operations as follows: (1) first, as laparotomy showed pale color in almost the extensive length of the small intestine, arterial bypassing of SMA was undertaken using SMA to the right common iliac artery bypass; (2) as the second-look operation on the next day, the terminal ileum was resected, and the remaining small intestine was able to be preserved. However, when the abdomen was tried to be closed, systemic blood pressure decreased to pre-shock condition, so the abdominal wall was closed at skin level with silastic sheet. (3) As the third-look operation on the 7th day, ileostomy was created, and the abdominal wall was safely closed. The postoperative course was uneventful. This case study shows that SMA grafting and staged operations might be an option to preserve the length of the small intestine when ISMAD is diagnosed as type VI.

[Staged surgery of Sanders type â £ calcaneal fractures with soft tissue three-degree swelling].

OBJECTIVE: To compare the clinical efficacy of staged surgery on Sanders Ⅳ calcaneal fractures with soft tissue Ⅲ swelling. METHODS: The clinical data of 76 patients with Sanders type Ⅳ closed calcaneal fracture with soft tissue three-degree swelling treated from June 2017 to May 2020 was retrospectively analyzed, including 54 males and 22 females, aged from 25 to 50 (38.16±10.24) years. The patients were divided into observation group and control group according to different treatment methods. Twenty-four patients in the observation group were treated by staged surgery stageⅠclosed prying traction reduction and Kirschner wire fixation, stageⅡopen reduction and internal fixation with titanium plate, including 17 males and 7 females, aged from 25 to 50 (36.12±9.56) years. There were 52 patients in the control group, including 37 males and 15 females, aged from 25 to 50 (38.32±10.67) years, these patients were treated with open reduction and internal fixation with titanium plate after the dermatoglyphic signs appeared. The swelling subsidence time, the length of hospitalization days, and the incidence of postoperative incision complications were compared between two groups. The Bhler angle, Gissane angle, and calcaneal varus angle were measured by X-ray before and 6 months after operation. American Orthopedic Foot and Ankle Society (AOFAS) about the ankle hindfoot score was used to evaluate the clinical efficacy. RESULTS: All 76 patients were followed up for 8 to 12 (9.52±2.01) months. The swelling subsidence time and hospitalization days in observation group were (12.12± 3.24) d and (24.53±6.44) d, respectively, which in control group were (15.16±4.16) d and (29.46±9.61) d, with statistical difference between two groups (P<0.05). Postoperative 6 months, Bhler angle, Gissane angle and calcaneal varus angle were (31.33±10.15)°, (145.34±8.04) ° and (10.31±3.23) ° in observation group, while those in control group were (20.24±8.23) °, (165.28±10.29) °and (21.24±5.27) °, with statistical difference between two groups (P<0.05). And there was significant difference in all patients between before and 6 months after operation (P<0.05). The AOFAS score of the observation group and control group were 71.76±9.84 and 57.23±10.76 at 6 months after operation, with significant different between two groups (P< 0.05). The excellent rate of observation group was significantly higher than that of control group (P<0.05). CONCLUSION: Compared with open reduction and internal fixation with titanium plate after the appearance of dermatoglyphic signs, staged surgery for Sanders type Ⅳ calcaneal fractures with soft tissue three-swelling does not increase the risk of soft tissue complications, and can significantly shorten the patient's swelling subsidence time and hospitalization days, improve the quality of fracture reduction and short term function, and relieve pain.

Long-term survival case of esophageal carcinosarcoma coexisting with alcoholic liver cirrhosis successfully treated by staged operation: A case report.

INTRODUCTION: Patients with esophageal cancers including carcinosarcoma sometimes have underlying liver cirrhosis because of a history of heavy drinking. It is definitely required to determine the appropriate surgical strategy and to manage the patients promptly when performing esophagectomy for the esophageal carcinosarcoma coexisting with alcoholic liver cirrhosis. PRESENTATION OF CASE: A 56-year-old male patient with a history of chest pain and difficulty swallowing was admitted to our hospital. He had a history of drinking 250 g of alcohol per day. Endoscopy revealed an irregular protruding tumor on the left wall of the lower-third thoracic esophagus. Computed tomography showed a tumor lesion in the lower-third thoracic esophagus; the images also showed irregularities on the surface of the liver, suggestive of coexisting alcoholic liver cirrhosis. The preoperative diagnosis was T3N2M0, Stage III esophageal leiomyosarcoma. In consideration of the underlying alcoholic liver cirrhosis, a staged operation was planned for this patient as a curative treatment. The patient had an uneventful postoperative clinical course and was discharged on the 47th day after the first surgery. Final histopathological diagnosis was T2N0M0, Stage II esophageal carcinosarcoma. The patient is alive without recurrence three years after surgery. DISCUSSION: This is the first report of long-term survival case of esophageal carcinosarcoma with alcoholic liver cirrhosis that was treated successfully by staged operation. CONCLUSIONS: Despite coexisting with alcoholic liver cirrhosis, staged operation could reduce the surgical invasiveness, so that very good short-term outcome and long-term survival was obtained in the patient with esophageal carcinosarcoma.

Thoracoscopy-thoracotomy approach for an aortoesophageal fistula: a case report.

An aortoesophageal fistula is often fatal, and standard radical surgery is highly invasive because both bilateral thoracotomy and laparotomy are required. We successfully incorporated thoracoscopic esophagectomy into this procedure for a 43-year-old man with an aortoesophageal fistula. After detaching the esophagus from the adjacent tissue, and leaving just the fistula in the right thoracoscopic procedure, we performed an open aortic graft replacement. Subsequently, we created an omental pedicle graft and wrapped it over the graft. Through this thoracoscopy-thoracostomy approach, minimal destruction of the right thoracic wall was achieved and the successful dissection of the diseased esophagus could be carried out while reducing the amount of bleeding during anticoagulation for cardiopulmonary bypass, and the field of view for the aortic replacement was not disturbed during left thoracotomy. Four months later, we reconstructed the esophagus by a pedunculated small intestinal graft through the ante-thoracic route. A thoracoscopy-thoracotomy approach is therefore considered to be effective and useful for treating a patient with an aortoesophageal fistula.

The application of stemic-pulmonary shunt in staged operation for tetralogy of Fallot with hypoplasia pulmonary arteries / 中华胸心血管外科杂志

Objective:The study aimed to evaluate the effect of systemic-pulmonary shunt(SPS) on the infants with tetralogy of Fallot(TOF) with hypoplasia pulmonary arteries.Methods:Among 949 infants less than three-year-old who underwent surgical intervention between January 2010 and December 2015, 853 infants underwent one-stage primary repair(group Ⅰ), whereas 96 infants underwent SPS(group Ⅱ). Among them, 546 were males and 403 were females. The average age and average weight at operation were 13 months and 9.4 kg, respectively. 20.8% infants had clinical symptoms before operation. Perioperative and follow-up parameters were assessed including age, weight, sex, transcutaneous oxygen saturation(SPO 2), preoperative clinic symptom, ratio of McGoon, NAKATA index, Z score of pulmonary annulus, left ventricular end diastolic diameter(LVEDD). Results:There were 28(3.0%) early postoperative deaths in the whole group. And no significant difference in mortality was found between group Ⅰ(2.9%) and group Ⅱ(3.1%). Compared with group Ⅰ, age and weight were significantly lower in patients in group Ⅱ[(0.95±0.56)years old vs.(1.09±0.59)years old] and[(8.6±1.8)kg vs.(9.5±2.1)kg], respectively. Patients in group Ⅱ had a lower SPO 2(0.75±0.09 vs. 0.85±0.09) and was more prone to appear hypoxic spell(30.2% vs. 19.7%) than patients in group Ⅰ. Patients in group Ⅱ had a more poor development in pulmonary artery. The ratio of McGoon, NAKATA index and Z score of pulmonary annulus in group Ⅱ were significantly less than that in group Ⅰ[1.4±0.3 vs. 1.9±0.5, (124±43)mm 2/m 2 vs.(222±88)mm 2/m 2 and-4.3±2.6 vs.-2.3±2.1], respectively. There was no difference of extubation time bewteen two groups. SPO 2 rose significantly from 0.75 to 0.83 after SPS. And after SPS, the diameter of main pulmonary artery, the ratio of McGoon, NAKATA index and Z score of pulmonary annulus increased significantly from 6.4 mm, 1.42, 126.4 mm 2/m 2 and -4.3 to 9.2 mm, 1.83, 212.6 mm 2/m 2 and -2.4, respectively. Moreover, LVEDD also increased significantly from 21.2 mm to 24.5 mm after SPS. Conclusion:SPS is safe and effective for little infants with anoxic spell and hypoplasia pulmonary arteries. SPS can improve oxygenation significantly and delay the age for radical surgery. SPS also promote the growth of the pulmonary arteries, pulmonary valve annulus and left ventricular, and it facilitates the preservation of pulmonary valve annulus and reduce the rate of transannular patching in a portion of infants.

[Study on the effect of simple incision of ventral tunica albuginea on the correction of penile curvature in hypospadias].

Objective: To investigate the therapeutic effect of simple tunica albugineaincision and ventral penile lengthening surgery on the correction of penile curvature due to asymmetry of the cavernous bodies in hypospadias. Methods: A retrospective analysis was performed in 39 children with hypospadias who underwent simple tunica albuginea incision and ventral penile lengthening surgery for correcting asymmetry of the cavernous bodies from January 2016 to December 2018(36 of them were from Department of Pediatric Urology surgery, The Children's Hospital, Zhejiang University School of Medicine, and 3 from Department of Urology surgery, Affiliated Hospital ofJiaxing University), all of whom aged from 0.5 to 5, with a median age of 1.1 years. During the first stage of the operation, firstly penile skin and sarcoma was released by completely degloving the skin and fascia of penis, secondly the factor of short urethral plate was solved by transection of urethral plate, and then the dorsal length of penis (A), the ventral length of the penis before and after straightening by incision of tunica albuginea (B and C) were measured and recorded; onto the second stage of the operation, an artificial erection test was performed to observe the curvature of the penis, the dorsal and ventral length of the penis (D and E) were measured. The dorsal and ventral length of the penis before and after straightening were compared. Results: The dorsal length of penis (A) was 33-39(35.6±3.2) mm, the length of ventral length of penis before straightening (B) was 28-35 (29.8±2.8) mm and the length of ventral length of penis after straightening (C) was 32-38 (34.3±2.1) mm, which were measured during the first stage of operation, and the difference between B and C was statistically significant (P<0.05), while the difference between A and C was not statistically significant (P>0.05). The dorsal length of penis (D) was34-41 (36.4±2.5) mm and the ventral length of penis (E) was 33-40 (35.7±3.6) mm, which were measured during the second stage of operation, and there was no significant difference between D and E (P>0.05). The degree of penile curvature at the time of erection was less than 15° by measuring with the side photos in all patients during 0.5 to 2.5 years of follow-ups with an average of 1.7 years. Conclusions: Penile curvature due to the asymmetry of the cavernous bodies could be effectively corrected by simple incision of ventral tunica albuginea, which showed a good result of early follow-up. The effect of this surgery on ventral penile straightening could be verified by measuring and comparing the ventral and dorsal length of penis during surgery.

Preoperative distal aortic diameter is a significant predictor of late aorta-related events after endovascular repair for chronic type B aortic dissection.

OBJECTIVES: Long-term therapeutic effects of thoracic endovascular aortic repair (TEVAR) for chronic type B aortic dissection remain controversial. This study aimed to evaluate the possible predictors of late aortic rupture and re-interventions after TEVAR. METHODS: We retrospectively reviewed the operative outcomes of 40 patients who underwent TEVAR for chronic type B aortic dissection at Kyushu University Hospital. During a mean follow-up period of 39.2 months, we assessed aortic morphology via computed tomography and then employed a multivariable Cox regression analysis in an attempt to identify the predictors of late aorta-related events. RESULTS: The early success rate of TEVAR was 100%. During the follow-up, however, three patients died from aortic rupture. Eight patients required aortic re-intervention, including thoraco-abdominal aortic graft replacement, repeated TEVAR, total arch replacement and EVAR. Multivariable Cox regression analysis revealed that the preoperative maximum distal aortic diameter was a significant predictor of late aorta-related events. The cutoff value of the distal aortic diameter was 40 mm. Freedom from aorta-related events was 94.6% at 1 year and 78.3% at 3 years. The survival rate was not significantly different despite the re-intervention. CONCLUSIONS: TEVAR is an effective treatment for chronic type B dissection, with acceptable mid-term results. The preoperative distal aortic diameter is a significant risk factor for late aorta-related events. When the maximum distal aortic diameter is ≥ 40 mm, a therapeutic strategy should be developed taking into consideration the possible need for aortic re-intervention.

[Comparison of early effectiveness and safety of simultaneous and staged bilateral unicompartmental knee arthroplasty for bilateral anteromedial compartment osteoarthritis].

OBJECTIVE: To compare the early effectiveness and safety of simultaneous bilateral and staged bilateral unicompartmental knee arthroplasty (UKA) in treatment of anteromedial compartment osteoarthritis. METHODS: The clinical data of 31 patients with bilateral anteromedial compartment osteoarthritis who underwent bilateral UKAs between January 2015 and January 2017 was retrospectively analyzed. Of them, 17 patients were treated with simultaneous bilateral UKAs (simultaneous group) and 14 patients with staged bilateral UKAs (staged group). There was no significant difference in gender, age, body mass index, osteoarthritis grading, and preoperative hip-knee-ankle angle, knee society score (KSS), visual analogue scale (VAS) score, and range of motion (ROM) of knee between the two groups ( P>0.05). The operation time, blood loss, hospitalization stay, minimum hemoglobin value during 10 days after operation, and hospitalization cost were recorded. The staged group was compared by the sum of two operations. The effectiveness was evaluated by KSS score, VAS score, ROM at 3, 6, 12 months after operation, and patient satisfaction scores were recorded at 12 months after operation. RESULTS: The operation time, hospitalization stay, and hospitalization cost of the simultaneous group were significantly lower than those of the staged group ( P<0.05). There was no significant difference in blood loss and the minimum hemoglobin value during 10 days after operation between the two groups ( P>0.05). Superficial infection occurred in 1 side of 1 case (7.1%) in staged group. Postoperative delirium occurred in 1 case (5.9%) in simultaneous group. There was no significant difference in incidence of postoperative complications between the two groups ( P=1.000). Patients in both groups were followed up 12-32 months (mean, 24.7 months). There was no significant difference in KSS score between the two groups at 3 months after operation ( t=0.896, P=0.392). KSS scores were significanly higher in simultaneous group than in staged group at 6 and 12 months after operation ( P<0.05). There was no significant difference in ROM and VAS scores between the two groups at 3, 6, and 12 months after operation ( P>0.05). At 12 months after operation, the patient satisfaction scores were significantly higher in simultaneous group than in staged group ( P<0.05). X-ray films showed no loosening of the prosthesis in the two groups. CONCLUSION: Simultaneous bilateral UKAs has the same security as staged bilateral UKAs. Meanwhile knee function recovery was better, hospitalization stay and hospitalization cost reduced, and patient satisfaction was higher in simultaneous bilateral UKAs.

Staged surgery for tandem cervical and lumbar spinal stenosis: Which should be treated first?

PURPOSE: Tandem spinal stenosis (TSS) refers to lumbar and cervical spinal canal stenosis. Staged surgery is often chosen, but sometimes, mere decompression of one stenosis is adequate to relieve symptoms. Therefore, we intend to analyze whether starting with the cervical or the lumbar region is the most logical option. METHODS: We retrospectively reviewed the data of 47 patients with TSS, having first-stage decompression for the most symptomatic stenosis, and classified into two groups (Group A: lumbar decompression first, Group B: cervical decompression first). Postoperative outcomes were analyzed for at least 2 years, and they were cautiously watched for symptoms of the non-operated stenosis; if such symptoms were debilitating, second-stage surgery for the non-operated stenosis was done. RESULTS: The demographic characteristics of Group A (n = 11) and Group B (n = 36) were comparable. One patient (9%) in Group A and 25 patients (67%) in Group B had resolution of symptoms and good functional recovery. The need for a second-stage surgery for the non-operated stenosis was significantly high (p = 0.001) among patients in Group A. They suffered a significant worsening of both the mJOA score and the Nurick's grade; whereas, patients in Group B experienced staged improvement of both scales. CONCLUSION: First-stage surgery for the cervical stenosis significantly lowers the need of the second-stage surgery. In contrast, if lumbar stenosis was treated first, a dramatic exacerbation of the symptoms related to the cervical stenosis can occur soon. Therefore, treatment of cervical stenosis first seems to be more appropriate. These slides can be retrieved under Electronic Supplementary Material.

Result of Staged Operation in Ruedi-Allgower Type II and III Open Tibia Pilon Fractures with Severe Comminution / 대한족부족관절학회지

PURPOSE: This study analyzed the clinical and radiological results of Reudi-Allgower type II and III open tibia pilon fracture patients who underwent plate fixation after the recovery of a soft tissue injury after external fixation. MATERIALS AND METHODS: From 2010 to 2015, this study analyzed 14 patients who were treated for open tibial pilon fractures and could be followed up at least one year. The mean age was 49 years and the average follow-up period was 19 months. An emergency operation was performed for external fixation and open wounds, and secondary surgery was performed for definitive fixation using a plate. The radiological and clinical evaluations were analyzed retrospectively. Complications, such as post-traumatic osteoarthritis and wound infections were also analyzed. RESULTS: The mean duration between two-staged surgery was 21 days and the mean bone union time was 9.2 months. Three cases of delayed union and one case of nonunion were reported. The malunion did not occur in all cases. The average American Orthopaedic Foot and Ankle Society (AOFAS) score was 68 points. A limitation of the ankle motion occurred in all cases. In four cases, wound infections due to initial open wounds occurred; one patient underwent a below the knee amputation due to chronic osteomyelitis. Post-traumatic arthritis occurred in 10 cases. CONCLUSION: Severe comminuted tibial plateau open fractures of Reudi-Allgower type II and III, which are high-energy injuries that result in extensive soft tissue damage, have a higher incidence of complications, such as ulcer problems and osteomyelitis, than closed tibia plateau fractures. Post-traumatic arthritis is the most common complication of tibia plateau open fractures, and staged surgery is recommended because of the relatively satisfactory clinical results.

Meanwhile knee function recovery was better, hospitalization stay and hospitalization cost reduced, and patient satisfaction was higher in simultaneous bilateral UKAs.

Staged Repair of Truncus Arteriosus Associated with Complete Atrioventricular Septal Defect.

We report a case of successful repair of truncus arteriosus (TA) associated with complete atrioventricular septal defect (c-AVSD) using a staged approach. TA associated with c-AVSD is a very rare congenital cardiac anomaly. No report of successful staged repair in South Korea has yet been published. We performed bilateral pulmonary artery banding when the patient was 33 days old, and total correction using an extracardiac conduit was performed at the age of 18 months. The patient recovered uneventfully and is doing well.

[Minimally invasive surgery for the severe degenerative lumbar scoliosis: two stage protocol].

Objective: To investigate the surgical outcome of minimally invasive surgery(MIS) for severe degenerative lumbar scoliosis(DLS) and put forward a two-stage MIS surgical strategy. Methods: Prospective study of MISDEF Ⅲ DLS patients from June 2016 to August 2017 in the Second Affiliated Hospital of Zhejiang University was carried out, excluding the patients whose apex vertebrae of scoliosis was above L(1/2) level or whose facet joint got spontaneous fusion. Fifty-three patients were included in this study for staging evaluation and MIS surgical treatment. Information was recorded, including gender, age, body mass index, follow-up period, pelvic incidence (PI), blood loss, operation time, visual analogue pain score (VAS), Oswestry disability index (ODI), complications in the perioperative period and follow-up period, and also the radiographic parameters such as scoliosis Cobb angle, the mismatch between pelvic incidence and lumbar lordosis (PI-LL), sagittalvertical axis (SVA), coronal balance (CB) before and after each stage of surgery or latest follow-up. The paired-samples t test was used to analyze the effectiveness of staging surgery. Results: Fifty-three patients (18 males and 35 females) were included in this study. All patients had completed clinical and the follow-up records, with an average follow-up period of 11.52 months (6-20 months). A total of 168 segments fusions were performed with CLIF, 113 segments were performed with anterior column realignment (ACR), the average correct angle was 15.6°±6.3°(7°-28°) in sagittal plane each level. After the stage Ⅰ surgery, lumbar scoliosis cobb had been corrected for 55.35%, after the stage Ⅱ surgery, rate of correction was 75.6%. PI-LL had been matched (-32.8°±14.9° to -2.5°±9.4°), SVA was changed from 5.7 cm to 0.6 cm, the stage Ⅰ rate of correction was 80.3 and stage Ⅱ was 88.8%, pelvic tilt (PT), lumbar lordosis (LL) and CB had been restored; 13 (24.5%) patients were performed paraspinal approach transforaminal decompression. The posterior minimally invasive fixation indexes: 11(20.8%) patients were performed paraspinal approach transforaminal multi-segment transforaminal osteotomy (TFO) and internal fixation; 36(67.92%) cases were performed paraspinal approach transforaminal multi-segment fixation; 6(11.33%) patients were treated with percutaneous pedicle screw fixation. The average fixed segments was 7.4±1.4 in each patient. The blood loss of stage Ⅰ and stage Ⅱ operation was (157±71) ml, (343±224)ml, respectively. The operation time was (214±60) min, (190±54)min respectively in the two stage operations. The low back pain and leg pain VAS score and ODI improved after the stage Ⅰ and Ⅱ surgery (t=17.948, 10.099, 14.619, all P<0.001). Conclusions: MIS for the severe degenerative lumbar scoliosis can achieve good clinical outcome and deformity correction. The two-stage protocol has the advantages of less complications and is well-tolerated.

Staged Repair of Truncus Arteriosus Associated with Complete Atrioventricular Septal Defect

We report a case of successful repair of truncus arteriosus (TA) associated with complete atrioventricular septal defect (c-AVSD) using a staged approach. TA associated with c-AVSD is a very rare congenital cardiac anomaly. No report of successful staged repair in South Korea has yet been published. We performed bilateral pulmonary artery banding when the patient was 33 days old, and total correction using an extracardiac conduit was performed at the age of 18 months. The patient recovered uneventfully and is doing well.

Ileum preserving expanded jejunectomy and pancreaticoduodenectomy with combined resection of the superior mesenteric artery for huge retroperitoneal solitary fibrous tumor.

We encountered a patient with a large retroperitoneal solitary fibrous tumor, in whom we could preserve approximately 150 cm of the ileum even after pancreaticoduodenectomy combined with resection of the superior mesenteric artery, thus preventing short bowel syndrome.
