Abstract. The development of surgical and postoperative management techniques has improved the treatment outcomes of esophageal cancer resection. However, respiratory morbidity is still the most frequent complication after esophagectomy. The objective of the present study was to identify risk factors for respiratory complications following resection for esophageal cancer. This study included 96 patients with esophageal cancer who had undergone esophagectomy with lymph node dissection. The patients were divided into 2 groups according to the presence (20 patients, 17 had pneumonia and 3 had acute respiratory distress syndrome) or absence (76 patients) of postoperative respiratory complications (PRC). The two groups were compared with respect to their preoperative clinical variables, such as age, body mass index, smoking history, serum albumin, serum C-reactive protein (CRP), number of lymphocytes, %VC, FEV1.0% and FEV1.0. Furthermore, multiple logistic regression analyses were used to estimate relative risk factors for respiratory complications. Results of the univariate analysis showed that smoking history (+/-, patients with PRC, 19/1 and without PRC, 53/23), serum CRP (≥1.0 mg/ dl/<1.0 mg/dl, patients with PRC, 6/14 and without PRC, 6/70) and FEV1.0% (≥60%/<60%, patients with PRC, 16/4 and without PRC, 73/3) were significantly different between the two groups. Multiple logistic regression analysis showed that FEV1.0% was the strongest predictor of PRC. FEV1.0%, serum CRP and smoking history are reliable predictors of the risk of respiratory complications following esophageal cancer resection. For patients with these factors, perioperative management for the prevention of postoperative respiratory complications should be considered.

Elevated serum CRP levels after chemoradiotherapy may predict poor response to chemoradiotherapy more accurately than before chemoradiotherapy, and IL-6 may be a possible target associated with chemoradiotherapy resistance.

SUMMARY Six patients in the neurosurgical ward of Fukushima Medical College Hospital suffering from ventriculitis due to Achromobacter xylosoxidans infection had undergone craniotomy or cranial trepanation before the infection. The strains of A. xylosoxidans isolated from the patients were resistant to streptomycin, ampicillin, cephaloridine, gentamicin, and colistin. They were also resistant to chlorhexidine digluconate (Hibitane) in a concentration of 2%. When a study of the chlorhexidine used in the hospital was carried out four strains of A. xylosoxidans were isolatedfrom 20 containers of chlorhexidine solution in the surgical ward but not from those in the operating theatre.

Despite recent technological advances in the treatment of hepatobiliary pancreatic disease, intractable external pancreatic fistula is still a major critical complication after pancreaticoduodenectomy, and the treatment strategy is not well defined. We report here a case that was successfully treated by our novel interventional internal drainage technique. A 62-year-old woman underwent pylorus-preserving pancreaticoduodenectomy for carcinoma of the papilla of Vater, with reconstruction by a modified Child's procedure. One year later, she was readmitted to our hospital because of external pancreatic fistula. Both computed tomography and fistulography demonstrated a pancreatic fistula derived from dehiscence of the pancreatico-jejunal anastomosis. The pancreatic fistula persisted for 1 week with conservative management. Therefore, we performed repeated fistulography and cannulation, using two comparatively stiff guidewires introduced into the main pancreatic duct and stenotic anastomosed jejunal lumen, respectively, and we placed an endoprosthesis, using bilateral guidewires to connect the two lumens. Consequently, the pancreatic fistula was successfully closed within a few days. Our novel technique is simple, rapid, and not costly. Therefore, it should be considered an effective treatment strategy for persistent pancreatic fistula following pancreaticoduodenectomy that fails to respond to initial conservative management and an endoscopic approach. Also, this technique is applicable to other intractable fistulous situations.
