Background The aim of the present study was to investigate the prognostic impact of transfusion following distal pancreatectomy (DP) for left-sided pancreatic ductal adenocarcinoma (PDAC). Methods Retrospective analysis was performed to identify prognostic factors in patients who underwent DP from July 1992 to October 2012. Results Forty-eight patients were male, and 35 were female with a mean age of 62 ± 9 years. Twenty-three (27.7%) of the patients received intraoperative blood transfusion. In univariate analysis, combined organ resection (P = 0.046), intraoperative transfusion (P

Background This study aimed to investigate the clinical relevance of splenic vein thrombosis (SVT) in the splenic vein remnant following minimally invasive distal pancreatosplenectomy (DPS). Methods Medical records of patients who underwent laparoscopic or robotic distal pancreatectomy (DP) with or without splenectomy between January 2006 and August 2012 were reviewed. Rates of SVT and clinically relevant postoperative pancreatic fistula (POPF) were compared in a group of patients undergoing DPS and a group having spleen-preserving DP. Results Seventy-nine patients had minimally invasive DP, of whom 38 (48 per cent) developed SVT in the splenic vein remnant. DPS was associated with POPF (P = 0·001) and SVT (P < 0·001). SVT length was closely related to the amount of peripancreatic fluid collection (P = 0·025) and POPF (P = 0·045). In a comparison of splenic vessel-sacrificing, spleen-preserving DP and DPS, postoperative platelet count was significantly higher in the DPS group (P < 0·001). In addition, grade of SVT (P = 0·092) and POPF (P = 0·065) tended to be associated with DPS, suggesting that SVT may be related to both splenectomy and POPF. Conclusion Minimally invasive DPS is associated with SVT and POPF. Preservation of the spleen should be considered when treating patients with benign and borderline malignant tumours of the distal pancreas.

목적 : 위암 환자에 있어서 위절제술 후 빈혈은 흔한 만성 합병증으로 알려져있다. 하지만 수술전, 수술중, 수술후 혈액학적 지표의 변화의 관계에 대한 연구는 잘 이루어지지 않았다. 본 연구에서는 혈액학적 지표를 포함하여 위 절제술 후 빈혈에 영향을 미치는 인자에 대해 살펴보았다. 방법 : 위절제술을 시행받은 227명의 환자를 대상으로 임상적 소견, 혈액학적 지표, 혈액내 철분 수치를 분석하였다. 또한, 수술 후 빈혈의 진단까지의 기간을 분석하였다. 결과 : 수술전 빈혈 환자는 99명이었고 그 중 24명은 철 결핍성빈혈이었다. Folate 와 cobalamine 결핍 환자는 없었다. 수술 직후 회복기를 관찰하였을 때 수술 방법에 따른 의미있는 혈액학적 소견의 차이는 없었다. 하지만 장기 추적 관찰시 위절제술후 빈혈에 관련된 세가지 위험 인자가 통계학적으로 의미있게 나타났다. 결론 : 위절제술 후 빈혈에 관여하는 위험 인자로는 수술전 철결핍성 빈혈, 수술후 7일째 낮은 헤모글로빈 수치, 수술 방법의 차이 등이 있었다. 특히, 수술전 철 결핍성 빈혈이 진단된 환자가 위절제술후 빈혈 환자의 절반에 가까운 비중을 차지해 수술전 철결핍성 빈혈의 진단과 치료가 위절제술 후 빈혈의 예방에 도움이 될 수 있다는 가능성을 생각해 볼 수 있다.

Few studies have evaluated the risk factors for in-hospital mortality in critically ill surgical patients who have undergone emergency gastrointestinal (GI) surgery. The aim of this study was to identify the risk factors associated with in-hospital mortality in critically ill surgical patients after emergency GI surgery. The medical records of 362 critically ill surgical patients who underwent emergency GI surgery, admitted to intensive care unit between January 2007 and December 2011, were reviewed retrospectively. Perioperative biochemical and clinical parameters of survivors and nonsurvivors were compared. Logistic regression multivariate analysis was performed to identify the independent risk factors of mortality. The in-hospital mortality rate was 15.2% (55 patients). Multivariate analyses revealed cancer-related perforation (odds ratio [OR] 16.671, 95% confidence interval [CI] 2.629–105.721, P = 0.003), preoperative anemia (hemoglobin

Air embolism following central venous catheter (CVC) removal is a relatively uncommon complication. Despite its rare occurrence, an air embolism can lead to serious outcomes. One of the most fatal complications is cerebral air embolism. We report a case of cerebral air embolism that occurred after the removal of a CVC in a patient with an underlying idiopathic pulmonary fibrosis, subcutaneous emphysema, pneumomediastinum, and a possible intrapulmonary shunt. Although the patient had a brief period of recovery, his condition deteriorated again, and retention of carbon dioxide was sustained due to aggravation of pneumonia. Despite full coverage of antibiotics and maximum care with the ventilator, the patient died about 5 weeks after the removal of the CVC. We suggest that strict compliance to protocols is required even while removing the catheter. Furthermore, additional caution to avoid air embolism is demanded in high-risk patients, such as in this case.

Purpose Herein, we firstly present the robotic single-site cholecystectomy (RSSC) as performed in Asia and evaluate whether it could overcome the limitations of conventional laparoscopic single-site cholecystectomy. Materials and Methods From October 2013 to November 2013, RSSC for benign gallbladder (GB) disease was firstly performed consecutively in five patients. We evaluated these early experiences of RSSC and compared factors including clinicopathologic factors and operative outcomes with our initial cases of single-fulcrum laparoscopic cholecystectomy (SFLC). Results Four female patients and one male patient underwent RSSC. Neither open conversion nor bile duct injury or bile spillage was noted during surgery. In comparisons with SFLC, patient-related factors in terms of age, sex, Body Mass Index, diagnosis, and American Society of Anesthesiologist score showed no significant differences between two groups. There were no significant differences in the operative outcomes regarding intraoperative blood loss, bile spillage during operation, postoperative pain scale values, postoperative complications, and hospital stay between the two groups (p
