Methods: A total of 120 patients with AIS who underwent posterior spinal fusion from August 2006 to March 2017 at our facility and were followed up for 2 years or more were included. Radiological parameters were measured on whole-spine anteroposterior and lateral radiographs. Revised SRS-22 (SRS-22r) values were also recorded. Coronal trunk imbalance was defined as a deviation of ≥2.0 cm between the C7PL and the central sacral vertical line. Patients with and without coronal trunk imbalance at 2 years after surgery were defined as D (+) (decompensation type) and D (-), respectively. Mean SRS-22r values, including function, pain, self-image, mental health, and subtotal were compared between the D (+) and D (-) groups. Logistic regression analysis was performed to detect the preoperative factors related to D (+) using predictors, including curve type, maximum Cobb angle, and coronal trunk imbalance. Results: At 2 years after surgery, the D (+) group had a significantly lower self-image in the domain of SRS-22r scores compared with the D (-) group. Preoperative coronal trunk imbalance was significantly related to D (+) but not to significant changes in the postoperative SRS-22 score in any of the SRS-22 domains. Conclusions Postoperative C7PL deviation lowers the self-image in patients with AIS. Patients with preoperative coronal trunk imbalance were significantly more likely to be D (+).

STUDY DESIGN: Retrospective chart review. PURPOSE: This study evaluated long-term surgical outcomes of computer-assisted reconstruction using transarticular or cervical pedicle screws for cervical spine lesions caused by advanced rheumatoid arthritis (RA). OVERVIEW OF LITERATURE: We routinely employ C1–C2 transarticular and cervical pedicle screw instrumentation to reconstruct advanced and unstable RA cervical lesions. However, few reports are available on the long-term results of surgical reconstruction for rheumatoid cervical disorders, particularly regarding cervical pedicle screw fixation. METHODS: Six subjects (all female) with RA cervical lesions who underwent atlantoaxial or occipitocervical fixation and were followed for at least 10 years were retrospectively studied. A frameless, stereotactic, optoelectronic, computed tomography-based image guidance system was used for correct screw placement. Variables including the Japanese Orthopaedic Association score, EuroQol, Ranawat value, and C2–C7 angle before and 2, 5, and 10 years after surgery were assessed along with the occurrence of subaxial subluxation (SAS). RESULTS: Mean age at initial surgery was 58.2±7 years (range, 51–68 years), and mean follow-up period was 141±11 months (range, 122–153 months). Lesions included atlantoaxial subluxation (AAS, n=2) and AAS+vertical subluxation (n=4). Mean C2–C7 lordotic angle before and 2, 5, and 10 years after surgery was 20.1°±6.1°, 21.0°±4.0°, 18.8°±4.7°, and 17.8°±5.3°, respectively. SAS did not occur in cases maintaining the C2–C7 lordotic angle. In two cases where the C2–C7 lordotic angle declined from 5 years postoperatively, SAS occurred at the C2–C3 level in one and at the C4–C5 level in the other, both of which required reoperation. CONCLUSIONS: Patients with rheumatoid cervical lesions who undergo atlantoaxial or occipitocervical fixation using C1–C2 transarticular or pedicle screws carry a risk of SAS for up to 10 years postoperatively, which may require reoperation.

SUMMARY OF EVENT: Bacterial, mycotic peritonitis and Candida fungemia developed in a patient with moderate ascites who had undergone endoscopic ultrasound-guided biliary drainage (EUS-BD). Antibiotics and antifungal agent were administered and ascites drainage was performed. Although the infection improved, the patient's general condition gradually deteriorated due to aggravation of the primary cancer and he died. TEACHING POINT: This is the first report to describe infectious peritonitis after EUS-BD. Ascites carries the potential risk of severe complications. As such, in patients with ascites, endoscopic retrograde cholangiopancreatography (ERCP) is typically preferred over EUS-BD or percutaneous drainage to prevent bile leakage. However, ERCP may not be possible in some patients with tumor invasion of the duodenum or with surgically altered anatomy. Thus, in patients with ascites who require EUS-BD, we recommend inserting the drainage tube percutaneously and draining the ascites before and after the intervention in order to prevent severe infection.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic inflammatory disease of the gastrointestinal tract, with increasing prevalence worldwide. IBD Ahead is an international educational program that aims to explore questions commonly raised by clinicians about various areas of IBD care and to consolidate available published evidence and expert opinion into a consensus for the optimization of IBD management. Given differences in the epidemiology, clinical and genetic characteristics, management, and prognosis of IBD between patients in Japan and the rest of the world, this statement was formulated as the result of literature reviews and discussions among Japanese experts as part of the IBD Ahead program to consolidate statements of factors for disease prognosis in IBD. Evidence levels were assigned to summary statements in the following categories: disease progression in CD and UC; surgery, hospitalization, intestinal failure, and permanent stoma in CD; acute severe UC; colectomy in UC; and colorectal carcinoma and dysplasia in IBD. The goal is that this statement can aid in the optimization of the treatment strategy for Japanese patients with IBD and help identify high-risk patients that require early intervention, to provide a better long-term prognosis in these patients.

Purpose: Integrated care pathway (ICP) is structured multidisciplinary care plan that aim to improve the quality of care. ICP could be effective in providing quality End-of-Life (EOL) care in long-term care facilities (LTCFs). However, the outcomes and components of ICP for EOL care in LTCFs are not clear. Methods: We conducted a scoping review to identify the outcomes and components. We searched electronic databases (PubMed, CINAHL, Cochrane Library, PsycINFO, Ichushi) and conducted an additional hand search for relevant journal articles related to EOL care. We searched intervention and implementation studies for ICP in EOL care in LTCFs. Results: Thirteen papers met the inclusion criteria. We identified the following components of ICP: documents, education regarding EOL care and ICP, support by experts, and regular conferences among care providers. The effects of ICP were reported as reductions in transfers to hospitals and improvement in staff confidence regarding EOL care. Conclusion: With reference to the components of ICP identified in this study, ICP should be developed based on the characteristics of LTCFs, and the effects of intervention or implementation studies using a more robust design should be examined.

　　Safe introduction of laparoscopic partial liver resection (LPLR) requires the selection of appropriate cases not exceeding the surgeon's skills as well as standardization of surgical procedures. After introduction at our institution, 60 LPLR procedures were performed between April 2010 and May 2016. To identify indices for case selection, short-term perioperative parameters were analyzed, including operative time, blood loss, postoperative complications, and postoperative hospital stay. Operative time was significantly shorter in the last 30 cases compared with the first 30 cases (182.5 min vs. 253 min; p＝0.023) and in 16 cases involving the left lobe (S2-4) compared with 44 cases involving the right lobe (S1, S5-8; 148.5 min vs. 246 min; p＝0.004). Blood loss was significantly less (0 mL vs. 50 mL; p＝0.028) and operative time was significantly shorter (185 min vs. 250 min; p＝0.048) in 27 cases with tumor diameter ＜2.5 cm compared with 33 cases with tumor diameter ≥ 2.5 cm. Operative time tended to be longer in 9 cases of multiple-site resection compared with 51 cases of single-site resection (207 min vs. 260 min; p＝0.085). BMI, pathology, and hepatitis virus status showed no significant difference in perioperative short-term results. For the introduction of LPLR, it may be preferable to select cases located in the left lobe with a tumor diameter ＜2.5 cm and to accumulate a certain amount of experience in similar cases first.

Surgical procedures for atlantoaxial (C1–C2) fusion in young children are relatively uncommon. The purpose of this study was to report on a surgical treatment for a case of atlantoaxial instability caused by os-odontoideum in association with quadriparesis and respiratory paralysis in a 5-year-old girl. We present the patient's history, physical examination, and radiographic findings, describe the surgical treatment and a five year follow-up, and provide a literature review. The instability was treated by halo immobilization, followed by C1–C2 transarticular screw fixation using a computed tomography-based navigation system. At the five year follow-up, the patient had made a complete recovery with solid union. The authors conclude that C1–2 transarticular screw fixation is technically possible as in a case of atlantoaxial instability in a five-year-old child.

STUDY DESIGN: Multicenter analysis of two groups of patients surgically treated for degenerative L4 unstable spondylolisthesis. PURPOSE: To compare the clinical and radiographic outcomes of posterolateral fusion (PLF) and posterior lumbar interbody fusion (PLIF) for degenerative L4 unstable spondylolisthesis. OVERVIEW OF LITERATURE: Surgery for lumbar degenerative spondylolisthesis is widely performed. However, few reports have compared the outcome of PLF to that of PLIF for degenerative L4 unstable spondylolisthesis. METHODS: Patients with L4 unstable spondylolisthesis with Meyerding grade II or more, slip of >10degrees or >4 mm upon maximum flexion and extension bending, and posterior opening of >5 degree upon flexion bending were studied. Patients were treated from January 2008 to January 2010. Patients who underwent PLF (n=12) and PLIF (n=19) were followed-up for >2 years. Radiographic findings and clinical outcomes evaluated by the Japanese Orthopaedic Association (JOA) score were compared between the two groups. Radiographic evaluation included slip angle, translation, slip angle and translation during maximum flexion and extension bending, intervertebral disc height, lumbar lordotic angle, and fusion rate. RESULTS: JOA scores of the PLF group before surgery and at final follow-up were 12.3+/-4.8 and 24.1+/-3.7, respectively; those of the PLIF group were 14.7+/-4.8 and 24.2+/-7.8, respectively, with no significant difference between the two groups. Correction of slip estimated from postoperative slip angle, translation, and maintenance of intervertebral disc height in the PLIF group was significantly (p<0.05) better than those in the PLF group. However, there was no significant difference in lumbar lordotic angle, slip angle and translation angle upon maximum flexion, or extension bending. Fusion rates of the PLIF and PLF groups had no significant difference. CONCLUSIONS: The L4-L5 level posterior instrumented fusion for unstable spondylolisthesis using both PLF and PLIF could ameliorate clinical symptoms when local stability is achieved.

STUDY DESIGN: Retrospective chart review. PURPOSE: A comparison of mini open foraminotomy (MOF) for cervical radiculopathy using either large tubular (LT) or TrimLine (TL) retractors. OVERVIEW OF LITERATURE: Posterior foraminotomy relieves compression of the cervical nerve root in radiculopathy patients. However, invasion of the paravertebral muscle may cause major problems in these patients. To address these problems, we performed MOF. METHODS: Twenty cervical radiculopathy patients (16 male and 4 female) who underwent MOF between May 2004 and August 2011 were assigned to LT and TL groups. Each group contained 10 subjects. Surgical and clinical outcomes were compared. RESULTS: The average operating time in the TL group was significantly shorter than that in the LT group. The final follow-up mean neck disability indices significantly improved compared to the preoperative values (LT group, 12.0+/-7.8 vs. 28.0+/-9.4; TL group, 6.0+/-5.9 vs. 21.9+/-10). The final follow-up neck pain visual analog scale (VAS) scores also decreased significantly from the preoperative of 8.0+/-1.5 and 2.5+/-2.5 to the final follow-up values of 2.2+/-2.2 and 1.0+/-2.5 in the LT and TL groups, respectively. The recovery rate for the neck pain VAS score was 70.0+/-31.9 in the LT group and 87.0+/-32.0 in the TL group, thus suggesting no significant difference between the two groups. CONCLUSIONS: MOF with the TL retractor is an easy and safe procedure. Furthermore, the use of the TL retractor allows for a minimally invasive and effective surgical treatment of cervical radiculopathy patients.

STUDY DESIGN: A retrospective study. PURPOSE: The present study aimed to evaluate mid-term results of cervical pedicle screw (CPS) fixation for cervical instability. OVERVIEW OF LITERATURE: CPS fixation has widely used in the treatment of cervical spinal instability from various causes; however, there are few reports on mid-term surgical results of CPS fixation. METHODS: Record of 19 patients who underwent cervical and/or upper thoracic (C2-T1) pedicle screw fixation for cervical instability was reviewed. The mean observation period was 90.2 months. Evaluated items included Japanese Orthopaedic Association (JOA) score and C2-7 lordotic angle before surgery and at 5 years after surgery. Postoperative computerized tomography was used to determine the accuracy of screw placement. Visual analog scale (VAS) for neck pain and radiological evidence of adjacent segment degeneration (ASD) at the 5-year follow-up were also evaluated. RESULTS: Mean JOA score was significantly improved from 9.0 points before surgery to 12.8 at 5 years after surgery (p=0.001). The C2-7 lordotic angle of the neutral position improved from 6.4degrees to 7.8degrees at 5 years after surgery, but this was not significant. The major perforation rate was 5.0%. There were no clinically significant complications such as vertebral artery injury, spinal cord injury, or nerve root injury caused by any screw perforation. Mean VAS for neck pain was 49.4 at 5 years after surgery. The rate of ASD was 21.1%. CONCLUSIONS: Our mid-term results showed that CPS fixation was useful for treating cervical instability. Severe complications were prevented with the assistance of a computed tomography-based navigation system.
