Background: Pneumonectomy is still a high-risk surgical procedure. Postpneumonectomy bronchopleural fistula is an especially severe complication with a high mortality rate. Although several reports have discussed risk factors for early bronchopleural fistula after pneumonectomy, only a few have reported them for late bronchopleural fistula. We reviewed cases of late bronchopleural fistula after pneumonectomy and investigated its risk factors. Methods: Sixty-four patients with nonsmall cell lung cancer underwent pneumonectomy at our institution from June 1999 to December 2004. Among them, 5 who developed bronchopleural fistula were investigated. Results: All of the 5 patients were male; 3 had undergone right pneumonectomy and 2 left pneumonectomy. The period between surgery and the appearance of bronchopleural fistula ranged from 36 to 164 days. We found that the preoperative serum albumin level was significantly lower in the patients with late bronchopleural fistula. Induction therapy, surgical side, age, anemia, arterial blood oxygen, and respiratory function did not affect the occurrence of bronchopleural fistula after pneumonectomy. Conclusions: A preoperative low-serum albumin level, indicative of poor nutritional status, is a risk factor for late bronchopleural fistula after pneumonectomy for nonsmall cell lung cancer. © 2010 The Editorial Committee of Annals of Thoracic and Cardiovascular Surgery.

Objective: This study was undertaken to evaluate a modified form of Estimation of Physiologic Ability and Surgical Stress (E-PASS) for surgical audit comparing with other existing models. Background: Although several scoring systems have been devised for surgical audit, no nation-wide survey has been performed yet. Methods: We modified our previous E-PASS surgical audit system by computing the weights of 41 procedures, using data from 4925 patients who underwent elective digestive surgery, designated it as mE-PASS. Subsequently, a prospective cohort study was conducted in 43 national hospitals in Japan from April 1, 2005, to April 8, 2007. Variables for the E-PASS and American Society of Anesthesiologists (ASA) status-based model were collected for 5272 surgically treated patients. Of the 5272 patients, we also collected data for the Portsmouth modification of Physiologic and Operative Severity Score for the enUmeration of Mortality and morbidity (P-POSSUM) in 3128 patients. The area under the receiver operative characteristic curve (AUC) was used to evaluate discrimination performance to detect in-hospital mortality. The ratio of observed to estimated in-hospital mortality rates (OE ratio) was defined as a measure of quality. Results: The numbers of variables required were 10 for E-PASS, 7 for mE-PASS, 20 for P-POSSUM, and 4 for the ASA status-based model. The AUC (95% confidence interval) values were 0.86 (0.79-0.93) for E-PASS, 0.86 (0.79-0.92) for mE-PASS, 0.81 (0.75-0.88) for P-POSSUM, and 0.73 (0.63-0.83) for the ASA status-based model. The OE ratios for mE-PASS among large-volume hospitals significantly correlated with those for E-PASS (R = 0.93, N = 9, P = 0.00026), P-POSSUM (R = 0.96, N = 6, P = 0.0021), and ASA status-based model (R = 0.83, N = 9, P = 0.0051). Conclusion: Because of its features of easy use, accuracy, and generalizability, mE-PASS is a candidate for a nation-wide survey. © 2010 Lippincott Williams & Wilkins.

Distal advanced gastric cancer (AGC) occasionally causes gastric outlet obstruction (GOO). We developed a laparoscopic stomach-partitioning gastrojejunostomy (LSPGJ) to restore the ability of food intake.This was a retrospective study performed at a single institution. Of consecutive 78 patients with GOO caused by AGC between 2006 and 2012, 43 patients who underwent LSPGJ were enrolled. The procedure was performed in an antiperistaltic Billroth II fashion, and the afferent loop was elevated and fixed along the staple line of the proximal partitioned stomach. Then, patients for whom R0 resection was planned received chemotherapy prior to laparoscopic gastrectomy. The primary end point was food intake at the time of discharge, which was evaluated using the GOO scoring system (GOOSS). Short- and long-term outcomes were assessed as secondary end points. Overall survival was estimated and compared between the groups who received neoadjuvant chemotherapy followed by surgery (NAC group), definitive chemotherapy followed by curative resection (Conversion group), and best supportive care (BSC group).The median operative time was 92min, blood loss did not exceed 30g in any patient, and postoperative complications (Clavien-Dindo grade2) were only seen in four patients (9.3%). The median time to food intake was 3days, and GOOSS scores were significantly improved in 41 patients (95.3%). Chemotherapy was administered to 38 patients (88.4%), of whom 11 later underwent radical resection, and 4 of 11 patients underwent conversion surgery following definitive chemotherapy. Median survival times were significantly superior in the NAC (n=7; 46.8months) and Conversion (n=4; 35.9months) groups than in the BSC group (n=26; 12.2months); however, the difference was not significant between the Conversion and NAC groups.LSPGJ is a feasible and safe minimally invasive induction surgery for patients with GOO from surgical and oncological perspectives.

To determine prognostic factors of methotrexate-associated lymphoproliferative disorder (MTX-LPD) and evaluate the efficacy and safety of biological therapy in rheumatoid arthritis (RA) complicated with MTX-LPD.Thirty RA patients who developed MTX-LPD were investigated in this study. We compared the clinical and laboratory parameters of patients who achieved regression of LPD by MTX withdrawal with those who required chemotherapy and evaluated the clinical course of RA after LPD development.Twenty-three patients (76.7%) achieved regression of LPD by MTX withdrawal. Chemotherapy-free patients had a tendency of shorter RA duration (13.1 vs. 22.0 years, p=0.108) and higher doses of MTX at LPD diagnosis (8.0 vs. 5.3mg/w, p=0.067) than patients who required chemotherapy. A significantly higher positive rate of peripheral blood Epstein-Barr virus (EBV)-DNA was observed in the chemotherapy-free group (9/9 vs. 0/3, p=0.0002). Of 15 patients that received biological agents after LPD development, 14 patients (93.3%) demonstrated an improved disease activity of RA and persistent remission of LPD, whereas only one patient experienced relapse of LPD during tocilizumab therapy.Peripheral blood EBV-DNA positivity is a potential prognostic marker of better outcome in MTX-LPD. Biological agents could be an option for the treatment of RA patients with MTX-LPD.

Conclusions: The current study suggests the possibility of surgical audit for postoperative OS in gastric cancer. Further studies including high-volume centers will be necessary to validate this idea.Background: Previous studies for surgical audit have focused on short-term outcomes, such as perioperative mortality. There has been no gold standard how to evaluate quality of care for long-term outcomes in surgical oncology. This preliminary study aims to propose a method for surgical audit targeting long-term outcome following gastrectomy for gastric cancer.Methods: We prospectively investigated a set of variables relating to physiologic conditions, tumor characteristics and operations in patients who underwent gastrectomy for gastric cancer between June 2005 and July 2008 in 18 referral hospitals in Japan. Overall survival (OS) is the endpoint. Cox hazard regression analysis was used to generate a model to predict OS. The calibration and discrimination power of the model were assessed using the Hosmer-Lemeshow (H-L) test and area under the receiver-operating characteristic curve (AUC), respectively. The ratio of observed-to-estimated 5-year OS rates (OE ratio) was defined as a measure of quality.Results: Among 762 patients analyzed, 697 (91 %) completed the 5-year follow-up. The constructed model for OS exhibited a good discrimination power (AUC, 95 % confidence interval 0.89, 0.86–0.91), which was significantly better than that for the UICC stage (0.81, 0.77–0.84). This model also demonstrated a good calibration power (H-L: χ2 = 27.2, df = 8, P = 0.77). The OE ratios among the participating hospitals revealed no significant variation between 0.74 and 1.1. © 2014, The International Gastric Cancer Association and The Japanese Gastric Cancer Association.

Background We developed a new method of intracorporeal gastroduodenostomy, the delta-shaped anastomosis, in which only endoscopic linear staplers are used. In this report, we present the short- and long-term outcomes of our initial experience with this procedure. Methods We retrospectively analyzed 100 consecutive gastric cancer patients who underwent the delta-shaped anastomosis procedure from May 2001 to November 2006. All of them underwent a laparoscopic distal gastrectomy with regional lymph node dissection. Quality of life was assessed with a questionnaire 6 months or more postoperatively, and the gastric remnant was evaluated by endoscopy one year following the surgery. Results Eight surgeons successfully performed the deltashaped anastomosis without any conversion to laparotomy. The learning curve for all surgeons was steep and the mean time for the anastomosis was 13 min. Only one patient developed an anastomotic leak, and the leak was minor. Sixty-five patients tolerated a 1500 kcal/day soft diet at the time of discharge. The mean follow-up period was 54.9 months. Only one patient reported symptoms indicative of dumping. Two patients were diagnosed with reflux esophagitis, and approximately 70% had evidence of bile reflux, but severe gastritis of the remnant stomach on endoscopy was uncommon. Conclusions The wide lumen of the delta-shaped anastomosis led to early, adequate postoperative oral intake without a significant incidence of dumping syndrome. The delta-shaped anastomosis is safe and simple and provides satisfactory postoperative results. © The International Gastric Cancer Association and The Japanese Gastric Cancer Association 2011.

A randomised, double-blind, phase II, dose escalation trial was conducted to assess the safety, tolerability and pharmacokinetics of the tyrosine kinase inhibitor nintedanib, alone and when added to ongoing pirfenidone therapy, in Japanese patients with idiopathic pulmonary fibrosis. 50 Japanese patients were randomised to receive nintedanib or placebo in one of three cohorts (nintedanib 50 mg twice daily or 100 mg twice daily for 14 days, or 150 mg twice daily for 28 days). Patients receiving pirfenidone at inclusion were stratified to every nintedanib dose group and placebo. Adverse events were reported in nine out of 17 patients receiving nintedanib alone and 10 out of 21 patients receiving nintedanib added to pirfenidone. All adverse events were mild or moderate in intensity. Gastrointestinal disorders were the most common adverse event. Maximum plasma concentration and area under the curve at steady state for nintedanib and its metabolites tended to be lower when nintedanib was added to pirfenidone. Nintedanib had no effect on the pharmacokinetics of pirfenidone. In conclusion, further study is needed to evaluate the safety and tolerability profile of nintedanib when added to pirfenidone in patients with idiopathic pulmonary fibrosis. There was a trend toward lower exposure of nintedanib when it was added to pirfenidone. Copyright © ERS 2015.

Neurological deficits following coil embolization of anterior circulation aneurysms due to the toxicity of contrast medium are rare. Here, we describe a patient with mild consciousness impairment and left hemiparesis following coil embolization of a large right middle cerebral artery aneurysm without evidence of ischemia or hemorrhage, who recovered completely with conservative treatment. The patients clinical course and radiological findings led us to conclude that the neurological deficits were due to the toxic effect of contrast medium used during the coil embolization.

In Japan, transabdominal preperitoneal (TAPP) inguinal hernia repair is performed by firmly pulling the peritoneum inwards to lift it from the underlying deep layer of subperitoneal fascia. It decreases the postoperative pain and discomfort in the inguinal area. The aim of this study was to evaluate the feasibility of the sandwich approach, which is a new technique for creating a preperitoneal space.The operation was performed via the sandwich approach. We made sure to protect the preperitoneal fascia areolar layer when making the preperitoneal space.We performed TAPP in 745 patients (876 hernias) treated between October 2006 and April 2015 at Himeji Medical Center and Kurashiki Central Hospital. Before October 2010, we did not use the sandwich approach, and recurrence was observed in three patients. From October 2010, we always used the sandwich approach and never experienced any cases of recurrence. Clavien-Dindo classification Grade 3 or higher postoperative complications occurred in 6 patients (0.8%) between October 2006 and April 2015. Mesh-related ileus was the most frequently observed morbidity. There were no cases of vas differentia or spermatic vessel injury, postoperative chronic pain, or urinary retention.The sandwich approach is feasible as another standard dissective procedure for TAPP.

A 45-year-old man with severe left flank pain was brought by ambulance to our hospital early in the morning. On arrival, his circulation dynamics were stable. His urinalysis results were normal, and ultrasonography showed no hydronephrosis. Abdominal dynamic computed tomography (CT) showed a huge retroperitoneal hematoma suspected of hemorrhage from a left adrenal artery aneurysm. After 3 hours of absolute bed rest, the patient experienced episodes of anemia, decreased blood pressure and increased pulse. Recheck of CT showed bleeding into the peritoneal cavity. Therefore, the patient was immediately treated with transcatheter arterial embolization.
