Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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. Patients with esophageal carcinosarcoma sometimes have underlying liver cirrhosis because of a history of heavy drinking. Postoperative severe complications often occur after esophagectomy in patients with liver cirrhosis. Staged operation could reduce the surgical invasiveness and manage these patients.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.
