Methods:
For this prospective multicenter study, 40 patients were followed up through radiologic and clinical examinations for at least 1 year postoperatively. All surgical procedures were either single- or double-level LLIF using bioactive porous titanium spacers without bone grafts.
Results:
Four patients were excluded from the study owing to aggravation from other comorbidities. Another 36 patients, including 26 and 10 with single- and double-level LLIFs, respectively, participated in the follow-up. The mean age at the time of surgery was 63.7 years. The mean operating time was 50.5 minutes per level. The mean estimated intraoperative blood loss was 11.6 mL per level. Clinical scores improved in all cases and were maintained throughout the follow-up period. The intervertebral bony union rates were 67.4% and 84.8% at 6 and 12 months, respectively. Endplate cyst signs were observed in 13.0% and 8.7% of patients at 6 and 12 months, respectively. Fused segmental angles were maintained throughout the follow-up period, indicating no cage subsidence.
Conclusions
Single- and double-level LLIFs using bioactive porous titanium spacers without bone grafts were found to be minimally invasive, resulting in clinical and imaging results comparable with conventional procedures. Therefore, this type of implant may be an option for minimally invasive spinal fusion surgery.

Simultaneous creation of an enterostomy for enteral nutrition during esophagectomy has been useful in our experience, but bowel obstruction associated with intestinal fistula remains a problem. Therefore, in this study, we retrospectively reviewed 18 patients with esophageal cancer who underwent transdiaphragmatic transgastric tube enteral feeding catheter placement during gastric tube reconstruction via the mediastinal route after esophagectomy from November 2012 to March 2014. The catheter was guided from the gastric tube into the gastrointestinal tract, with the tip placed in the jejunum distal to the ligament of Treitz. From the gastric tube, the catheter was guided along the diaphragm to the anterior abdominal wall through the extraperitoneal route. No bowel obstruction associated with catheter placement has been observed in any of the patients from the time of surgery to this writing. Also, the procedure enabled jejunostomy use for more than 5 years, similar to conventional jejunostomy. We experienced 1 case of catheter deviation into the mediastinum. Overall, transgastric tube enteral feeding catheter placement for reconstruction of the posterior mediastinal gastric tube was useful for avoiding intestinal obstruction associated with jejunostomy. However, there may be a risk of catheter displacement into the mediastinum.

Retrospective cohort study. This study aimed to evaluate aggravated lateral recess stenosis and clarify the indirect decompression threshold by combined lateral interbody fusion and percutaneous pedicle screw fixation (LIF/PPS). No previous reports have described an effective radiographic indicator for determining the surgical indication for LIF/PPS. A retrospective review of 185 consecutive patients, who underwent 1- or 2-level lumbar fusion surgery for degenerative spondylolisthesis (DS). According to their symptomatic improvement, they were placed into either the “recovery” or “no-recovery” group. Preoperative computed tomography (CT) images were evaluated for the position of the superior articular processes at the slipping level, followed by a graded classification (grades 0–3) using the impingement line (I line), a new radiographic indicator. All 432 superior articular facets in 216 slipped levels were classified, and both groups’ characteristics were compared. There were 171 patients (92.4%) in the recovery group and 14 patients in the no-recovery group (7.6%). All patients in the no-recovery group were diagnosed with symptoms associated with deteriorated bony lateral recess stenosis. All superior articular processes of the lower vertebral body in affected levels reached and exceeded the I line (I line-; grade 2 and 3) on preoperative sagittal CT images. In the recovery group, most superior articular processes did not reach the I line (I line+; grade 0 and 1; In DS cases that are classified as grade 2 or greater, the risk of aggravated bony lateral recess stenosis due to corrective surgery is high; therefore, indirect decompression by LIF/PPS is, in principle, contraindicated.

A 70-year-old man with continuous diarrhea for over 1 month consulted a primary care doctor. He was treated with oral antibiotics and probiotics but his condition worsened. He developed generalized edema and was referred to our hospital. Abdominal ultrasound and computed tomography (CT) scan findings were suggestive of colon cancer with accompanying liver metastasis. Total colonoscopy and endoscopy for pathological diagnosis led to a diagnosis of cancer of the sigmoid colon accompanied with liver metastasis or liver abscess. We planned to perform sigmoidectomy with simultaneous resection of the liver lesion. However, we considered that he was not particularly fit to undergo two concurrent surgeries. Therefore, based on his physical condition, we planned to first do a sigmoidectomy. Before surgery, the fever persisted and a repeat CT scan showed deterioration of the liver lesion. We diagnosed the liver lesion as abscess and performed percutaneous transhepatic abscess drainage (PTAD). Three days after PTAD, we then performed sigmoidectomy. Subsequently, the liver abscess resolved and gradually disappeared. At 5 years after surgery, there has been no recurrence of the cancer or abscess.

In our hospital, we typically perform laparoscopic partial gastrectomy as surgical treatment for extragastric growth type of submucosal tumor (SMT), and laparoscopic intragastric surgery for intragastric growth type. In 2008, laparoscopic and endoscopic cooperative surgery (LECS) was reported for the first time by Hiki et al. Against the background of LECS as laparoscopic local gastric resection with endoscopic resection, we started LECS for gastric SMT from 2015. We performed laparoscopic (LAP) surgery for 15 gastric SMT cases from 2009, and compared 5 cases for which LECS was performed and 10 cases for which LAP was performed. Tumor diameter was 15–21 mm (mean 19.2 mm) in the LECS group, and 20–53 mm (mean 35.5 mm) in the LAP group; the LECS group had a significantly smaller tumor diameter. Operative time was 299 ± 45 min in LECS and 222 ± 25 min in LAP. The volume of blood loss was 24 ± 13 mL in LECS and 33 ± 13 mL in LAP. Hospitalization days was 14.0 ± 3.0 days in LECS and 12.9 ±0.8 days in LAP. There was no significant difference between them.

A 17-year-old male was admitted to our hospital because of strong abdominal pain. His symptoms gradually worsened even after hospitalization, and contrast computed tomography (CT) revealed hemorrhage in the abdominal cavity. Interventional radiology (IVR) was performed to identify the bleeding site. No obvious source of bleeding was identifiable on IVR, so we opted to perform laparoscopic examination and hemostasis. The intraperitoneal finding was hematoma in the omentum, and omentectomy was performed for idiopathic omental hemorrhage because there was no history of trauma. The postoperative course was good and the patient was discharged after postoperative day 4. Performing laparoscopic surgery for omental hemorrhage facilitated minimally invasive treatment with a short hospital stay.

We report here 2 cases of traumatic diaphragmatic hernia. Case 1 was a 76-year-old man who was injured in a road traffic accident (RTA). Chest X-ray and computed tomography (CT) revealed prolapse of the stomach into the left thoracic cavity. We performed laparotomy with a diagnosis of traumatic left diaphragmatic hernia. A 12-cm hole was seen in the central tendon of the left diaphragm and this was repaired by suturing. Case 2 was a 75-year-old man who was also injured in an RTA. Chest X-ray and CT revealed prolapse of the stomach and transverse colon into the left thoracic cavity. We performed laparotomy with a diagnosis of traumatic left diaphragmatic hernia. A 15-cm hole was seen in the central tendon of the left diaphragm and this was repaired by suturing. Traumatic diaphragmatic hernia is a relatively rare condition and one that requires surgical repair. It is important to make prompt diagnosis with appropriate radiological investigations. Additionally, patients with diaphragm hernia caused by blunt trauma often have injuries to other organs. Care should be taken so as not to miss associated injuries.

Objective: In 2000, the Ministry of Health and Welfare issued an advisory that recommended intake of 0.4mg of folic acid in dietary supplements to reduce the risk of development of neural tube defects. Since subsequent reports of questionnaire surveys by various investigators showed a low in the intake rate, we surveyed and evaluated the folic acid intake rate among the pregnant women consulting the Japan Drug Information Institute in Pregnancy.
Methods: We evaluated differences in folic acid intake rate according to the consulting women’s background factors. i.e., age, pregnancy planning, pregnancy history, and taking of anticonvulsant drugs in the 1053 women capable of participating in the survey among the 1061 pregnant women who requested a consultation with the Japan Drug Information Institute in Pregnancy between April 2006 and August 2008.
Results: According to the result of our survey, the intake rate of folic acid was 29% of the 1053 pregnant women. The only 3 women of the 42 pregnant women taking anticonvulsant drugs took folic acid before they got pregnant.
Conclusion: Even now, 8 years after the Ministry of Health and Welfare advisory, the folic acid intake rate is low. Drawing upon successful measures promoting intake in the U.S. and Canada,we play a vital role in delivering this critical health information to pregnant women.
