Abstract  The patient was a 46-year old Japanese female who had undergone wide excision of the iliac bone and hip transposition at our institute's orthopedics department 2 years earlier. She presented with a growing incisional hernia and was transferred to our gastroenterological surgery department for surgical treatment. We planned a mesh repair for the incisional hernia, which protruded over the right iliac bone. The dimensions of the abdominal defect were 15×9 cm, and we used prolene mesh to repair the defect. The mesh was fixed at the inner part of the iliac bone, folded back at the iliac horn and fixed to the abdominal oblique muscles. The postoperative course was smooth, and recurrence was not seen at 3.5 years after the operation. An incisional hernia as seen in this patient's case is very rare, but we found that the underlay technique and prolene mesh were very useful for the three-dimensional hernia repair.

Abstract The operative mortality and morbidity of pancreaticoduodenectomy (PD) remain high. We analyzed PD patientsʼ clinical characteristics and surgical outcomes and discuss how PD clinical outcomes could be improved. We retrospectively reviewed the cases of 400 patients who underwent a PD between January 1998 and April 2014 at Okayama University Hospital, a very-high-volume center. We identified and compared the clinical outcomes between two time periods (period 1: 1998-2006 vs. period 2: 2007-2014). The total postoperative mortality and major complication rates were 0.75 and 15.8 , respectively, and the median postoperative length of stay (LOS) was 32 days. Subsequently, patients who underwent a PD during period 2 had a significantly shorter LOS than those who underwent a PD during period 1 (29 days vs. 38.5 days, p<0.001). The incidence of mortality and major complications did not differ between the two periods. In our multivariate analysis, period 1 was an independent factor associated with a long LOS (p<0.001). The improvement of the surgical procedure and perioperative care might be related to the shorter LOS in period 2 and ot the consistently maintained low mortality rate after PD. The development of multimodal strategies to accelerate postoperative recovery may further improve PDʼs clinical outcomes.

Abstract We reviewed post-operative complication and mortality rates from 1995 through 2014 and evaluated the changes in those rates across that 20-year period. Two thousand and three hundred sixteen patients with lung cancer underwent resection at our institution between 1995 and 2014. This timespan was divided into four 5-year periods. Each patientʼs age, Charlson comorbidity index score, and extent of surgery in each 5-year period were summarized, and the changes in these factors over the 20-year span were evaluated. The complication and mortality rates were calculated for each 5-year period, and the changes in those rates over the 20-years were evaluated. The number of patients with higher Charlson comorbidity index scores increased during the 20-year period. Of the 455 patients who developed complications, 97 developed life-threating complications. There were 16 post-operative deaths and 23 in-hospital deaths. There were no significant changes in the complication rate or mortality rate during the 20-year period. Both rates were significantly correlated with the extent of resection. Although the number of patients with comorbidities increased in the 20-year period, the post-operative complication and mortality rates, as well as in-hospital mortality, did not change significantly.

Abstract In minimally invasive partial nephrectomy (MIPN), it is important to preoperatively predict the degree of difficulty of tumor resection. When severe adhesions occur between the renal capsule and perinephric adipose tissue, detachment can be difficult. Preoperative prediction of adhesion is thought to be useful in the selection of surgical procedure. Subjects were 63 patients of a single surgeon who had received MIPN between April 2008 and August 2013 at Okayama University Hospital. Of these patients, this study followed 47 in whom the presence or absence of adhesions between the renal capsule and perinephric adipose tissue was confirmed using intraoperative videos. Data collected included: sex, BMI, CT finding (presence of fibroids in perinephric adipose tissue), comorbidities and lifestyle. Adhesion was observed in 7 patients (14.9%). The mean operative time was 291.6min in the adhesion group, and 226.3min in the group without. The increased time in the adhesions group was significant (p<0.05). Predictive factors were a positive CT finding for fibroid structure and comorbidity of hypertension (p<0.05). In MIPN, difficulty of surgery can be affected by the presence of adhesion of the perinephric adipose tissue. Predicting such adhesion from preoperative CT is thus important.

Abstract  Primary mucinous adenocarcinoma of the duodenum is rare. Here we report a case we recently encountered, and we review 16 cases reported in Japan. An 82-year-old Japanese woman was admitted to our hospital complaining of abdominal pain and heartburn. An endoscopic examination revealed a Type 2 tumor in the descending limb of the duodenum, and endoscopically obtained specimens revealed a poorly differentiated adenocarcinoma. We performed a curative pancreatoduodenectomy with lymph node resection, and the surgical specimen revealed that the duodenum was the primary site of the mucinous adenocarcinoma. The patient is currently alive > 1 year after the operation without any evidence of recurrence. Of the 16 patients reviewed, all patients had advanced tumors those depth were T3-T4. 9 patients had lymph node metastasis and 4 patients had peritoneal dissemination at the time of surgery. Since mucinous adenocarcinoma of the duodenum is often progressive cancer at a diagnosis, which is tend to have a worse prognosis than other histological types.

Abstract Computer-assisted spinal surgery is becoming more common; however, this is the first technical report to describe the technique of minimally invasive spinal posterior lumbar interbody fusion (MIS-PLIF) without using C-arm fluoroscopy. The authors report 2 years of follow-up of a 49-year-old female patient with L4 degenerative spondylolisthesis. The patient suffered from low back pain and intermittent claudication for more than 6 years. The authors performed computer-assisted MIS-PLIF without C-arm fluoroscopy. Instead, O-arm® navigation, the use of which reduces radiation exposure to patients as well as others in the operating room, was employed. Surgery was successful, and correct lumbar alignment was maintained. She had neither neurological deficits nor low back pain at her 12-month final follow-up. In conclusion, computer-assisted MIS-PLIF without C-arm fluoroscopy is a useful technique that reduces radiation exposure to the surgeon and operating room staff.

Abstract The effects of stone composition on transurethral lithotripsy (TUL) have not been sufficiently elucidated. The purpose of this study was to identify how calcium phosphate stone composition impacts TUL. Two hundred eighty-nine cases of semi-rigid and/or flexible TUL for upper urinary tract calculi were reviewed retrospectively. Inclusion criteria were a preoperative assessment by noncontrast computed tomography (NCCT) and a stone composition analysis. Small stones and those without calcium composition were excluded. Stone core radiodensity (SCR) was measured by taking the average of the upper 3 of 5 points in the proximity of the center of the stone on NCCT. Fifty-three patients with calcium phosphate composition (CaP) and 118 patients with calcium oxalate and without phosphate composition were eligible for analysis. SCR was significantly higher in the CaP group (p<0.01). The CaP patient group needed a significantly longer operation time (p=0.014) and more laser energy (p=0.085), and tended to have a lower rate of complete lithotripsy (p=0.096) and higher incidence of postoperative pyelonephritis (p=0.181). Stones containing calcium phosphate are harder, demand more laser energy, and require a longer operating time. NCCT evaluation can estimate stone composition preoperatively, and may be a useful tool for predicting operative outcomes.

Abstract We evaluated the usefulness of preoperative 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) examinations to predict the pathological features in primary breast cancer. In particular, we evaluated the correlation between the maximum standardized uptake values (SUVmax) obtained by 18F-FDG PET/CT and the Ki67 expression in estrogen receptor (ER)-positive invasive ductal carcinoma (IDC). Primary IDC patients operated between March 2009 and July 2013 at Okayama University Hospital were enrolled. We evaluated the correlations between the SUVmax and age, postoperative pT, histological grade, lymph vascular invasion, status of hormone receptor, human epidermal growth factor receptor 2 (HER2), Ki67 expression and node status. The Ki67 expression was classified as high (>14%) versus low (<14%). We enrolled 138 patients with IDC. Their median SUVmax was 3.85 (range:0-52.57). In a univariate analysis, the SUVmax was significantly related to age, pT, histological grade, lymphovascular invasion, hormone receptor status, HER2 status, node status and Ki67. In the 113 patients with ER-positive IDC, there was a significant correlation between Ki67 and SUVmax (p=0.0030). The preoperative 18F-FDG PET/CT results of IDC patients had significant relationships with pathological status parameters. The determination of the preoperative SUVmax might help classify Luminal A and Luminal B patients among luminal-type breast cancer patients.

Abstract A 46-year-old man was found to be positive for occult blood at a medical checkup and was revealed to have a 14-cm tumor on the right side of abdominal aorta by a subsequent abdominal CT scan. The endocrinology laboratory data showed elevations in the levels of serum noradrenaline, and ectopic pheochromocytoma was suspected. The tumor was compressing the inferior vena cava and portal vein, the superior mesenteric artery and the pancreas. Since it would be difficult to cure by operation, neoadjuvant therapy was started using radioisotope therapy by I-131 metaiodobenzylguanidine (131I-MIBG) and chemotherapy (CVD therapy ; cyclophosphamide, vincristine, dacarbazine). He was treated with three courses of radioisotope therapy and 16 courses of chemotherapy, which significantly reduced the tumor size. This made radical resection possible ; we were able to avoid the merger excision of great vessels and other organs. On pathological and immunopathological findings, the tumor was diagnosed as ectopic pheochromocytoma. Regarding the safety and curability of the treatment, neoadjuvant therapy may be useful in treating very large tumors that show invasion of other organs.

Title Alternative Non-high-output cardiac failure in patients undergoing hemodialysis through an arteriovenous shunt
FullText URL 127_203.pdf
Author Ugawa, Toyomu|
Abstract Background: Hemodialysis-related heart failure has been considered to be associated with excessive blood flow through the arteriovenous (AV) shunt used for vascular access. However, some patients undergoing dialysis have heart failure in the absence of an increase in cardiac output (CO) related to shunt blood-flow loading because the loading cannot be compensated for by increasing CO. This condition may be challenging to manage ; thus, early diagnosis is important. Methods and Results: Twelve patients (mean age, 71 years ; 9 men) with end-stage renal disease, dialysis-related heart failure, a high brain natriuretic peptide (BNP) level, and a mean New York Heart Association (NYHA) class of II underwent AV shunt closure. Their cardiac index (CI), pre- and post-dialysis BNP levels, and several cardiac variables were assessed pre- and postoperatively. All patients achieved relief of heart failure symptoms and a reduction in NYHA class after AV closure, but six patients had a postoperative increase in CI (the "non-high-output" cardiac failure group), whereas the other six had a decrease in CI (the "high-output" cardiac failure group). The high-output patients had greater improvements in BNP levels and most cardiac variables compared to the non-high-output group ; therefore, the heart failure in the non-high-output patients was considered more serious than that in the high-output group. Conclusions: The selection of effective strategies for treating dialysis-related heart failure may depend partly on identifying which patients have non-high-output failure. Such identification requires serial measurements of BNP levels and evaluations of cardiac variables other than the ejection fraction.
