SUCCESSFUL ENDOSCOPIC CLOSURES OF COLONIC PERFORATIONS REQUIRING ABDOMINAL DECOMPRESSION AFTER ENDOSCOPIC MUCOSAL RESECTION AND ENDOSCOPIC SUBMUCOSAL DISSECTION FOR EARLY COLON CANCER

Endoscopic submucosal dissection (ESD) for colorectal cancer is not widely accepted because of its technical difficulty and the risk of perforation. In addition, the risk of peritonitis cannot be completely eliminated even if a perforation is closed successfully. Reported here are two cases of early colon cancer in which the patients sustained iatrogenic perforations of the ascending colon during conventional endoscopic mucosal resection and of the sigmoid colon during ESD, respectively, requiring abdominal decompression with an 18 G Medicut needle. Both of these perforations were successfully treated by endoscopic clipping. In conclusion, conservative medical management may be possible in patients who have undergone successful closure of colonic perforations using endoscopic clipping. In order to perform immediate endoscopic closure, abdominal decompression has been useful to decrease patient discomfort and colonic lumen collapse. Now, CO₂ insufflation is being used effectively for the prevention of pneumoperitoneum.     

下颈椎骨折脱位伴关节突交锁的治疗策略选择

[目的]探讨并评估在下颈椎骨折脱位伴关节突交锁时安全、简便和有效的治疗策略。[方法]对16例创伤性下颈椎骨折脱位伴关节突交锁的患者于清醒状态及X线透视机监视下先行早期持续闭合颅骨牵引复位。所有患者在治疗前均行X线片和MRI/CT检查及ASIA神经功能评级。持续闭合牵引复位时行动态ASIA神经功能评级及X线透视机监视。损伤至开始牵引复位的间隔平均为31 h(6~52 h)。复位成功后维持颅骨牵引并择期行颈前路或颈前后路联合手术。9例患者于复位成功后再次行MR I扫描。[结果]治疗前MRI显示分别有8例和5例患者存在脱位节段的椎间盘突出和损坏;ASIA神经功能评级分别为:C级7例,D级5例,E级4例。16例患者均闭合复位成功且无一例出现神经功能恶化。复位成功后再次MRI扫描显示:6例脱位节段的椎间盘突出中有2例接近自动回纳,4例仍维持原样;3例脱位节段的椎间盘损坏中有2例维持原样,另1例转变为椎间盘突出。平均牵引重量为19 kg(10~32kg),平均牵引时间为53 min(30~135 min)。[结论]当患者处于清醒及检体合作的状态下通过动态神经功能评级及X线透视机监视,对下颈椎骨折脱位伴关节突交锁行早期持续闭合颅骨牵引复位,择期根据全身及局部状况行颈前路或颈前后路联合手术是一种安全、简便和有效的治疗策略。

Performance measures for evaluating services for people with a first episode of psychosis

Aim: The purpose of this project was to operationalize and apply a previously identified set of performance measures designed to evaluate services for those experiencing a first episode of a schizophrenia spectrum disorder. Methods: Operational definitions were developed for previously identified measures through an iterative process of discussions between clinical experts and health‐care evaluators. Data were collected from existing sources including corporate databases, clinical databases and chart review. Results: Definitions were developed for 44 measures covering seven of eight domains recommended for service level evaluation by the Canadian Institute for Health Information domains. Forty measures could be calculated. Conclusions: The measures represent a comprehensive set of performance measures suitable for the evaluation of services for people with a first‐episode psychosis. The measures could be used by other services in order to establish standards and norms for routine clinical practice.     

Bipolar disorder in children and adolescents: obstacles to early diagnosis and future directions

Aim: This article reviews research centred around juvenile bipolar disorder with particular reference to diagnostic difficulties. Putative deficits are scrutinized with respect to trait likelihood and the roles of neuropsychology and neuroimaging in enhancing our understanding of juvenile bipolar disorder are discussed. Methods: Search terms including childhood, adolescent, youth and juvenile combined with the terms ‘bipolar disorder’, mania, depression and hypomania were used to identify relevant studies in MEDLINE and PsychLit. Results: Over recent years research into this relatively new disorder has increased phenomenally. Key issues within the field include diagnostic specificity, the heritability of the disorder, the impact of comorbidity and the implications of neuropsychological and neuroimaging findings. Conclusion: Despite concerning controversies in literature the diagnosis of bipolar disorder in children and adolescents as compared with adults, promising future research directions include better neurological characterization of the disorder through the application of findings from clinical populations, neuropsychological and neuroimaging research.     

Is endoscopic one‐piece mucosal resection essential for early gastric cancer?

Background: Endoscopic mucosal resection (EMR) is widely accepted as a minimally invasive treatment for early gastric cancer (EGC) in Japan. However, the criteria for EMR must be strictly adhered to otherwise patients will miss the chance for additional therapy. We assess the important factor in expanding the indication of EMR. Methods: We investigated 1101 EGCs that had been resected by EMR at the National Cancer Center Hospital (NCCH), Tokyo, Japan, according to the indication recommended by Japanese Gastric Cancer Association (JGCA) and the expanded indication proposed by NCCH. Curability and local recurrence of the EMRs were assessed related to the applied indication and the number of resected specimens. Results: The recurrence rate of non‐evaluable resection was higher than that of evaluable resection (P < 0.0001). Eighty‐three lesions among 772 lesions in the JGCA group were non‐evaluable. Thirty‐seven leisons among 329 lesions in the NCCH group were non‐evaluable. There was no difference in the rate of non‐evaluable resection between JGCA and NCCH groups (P = 0.8329). However, the rate of curative resection was lower in the NCCH group than in the JGCA group (P = 0.0009). In piecemeal resection, there was no difference in the rate of non‐evaluable resection between JGCA and NCCH groups (P = 0.0527). In one‐piece resection, the rate of non‐evaluable resection was lower in the NCCH group than the JGCA group (P = 0.0137). Conclusion: Based on our series of cases, we propose one‐piece resection as a gold standard for EMR because it enables accurate histological evaluation, even in the EMR, according to the expanded indication.     

Enteral versus parenteral nutritional support in acute pancreatitis: A clinical review

Abstract   A critical analysis of the trials comparing enteral with parenteral nutritional support in acute pancreatitis is presented with particular scrutiny of the clinical endpoints in each trial. The heterogeneity of the trials and the discrepancies in caloric intake between enterally and parenterally fed patients are discussed. The hazards of each route of nutritional support are highlighted and the concept of 'nutritional bioavailability' in the context of acute pancreatitis is introduced. It is concluded that although there is evidence to support enteral feeding as the preferred option, both routes have a role.     

A CASE OF EARLY GASTRIC CANCER ACCOMPANIED BY DIEULAFOY ULCER IN A YOUNG WOMAN

A case of early gastric carcinoma accompanied by Dieulafoy ulcer is presented. The patient, a 26‐year‐old female, visited our emergency room with chief complaints of massive hematemesis and tarry stool. The initial endoscopic examination revealed a superficial depressed lesion with a faded color accompanied by a tiny ulcer with converging folds at the anterior wall of the middle gastric body. Although no active bleeding vessel was found at that time, the patient was admitted to our hospital for further check‐ups and treatment. On the 6th hospital day, she developed massive hematemesis resulting in shock. Urgent endoscopy, this time, disclosed an exposed bleeding vessel at the small ulcer floor previously mentioned, and endoscopic hemostasis was achieved. Since, however, a biopsy at initial examination from the surrounding depressed area proved carcinoma, a partial distal gastrectomy was subsequently carried out. Histological examination of the resected specimen confirmed the diagnosis of carcinoma limited to the mucosa and submucosa along with findings consistent with Dieulafoy ulcer. This is a rare case of combination of early cancer and Dieulafoy ulcer particularly in such a young patient. A review of the literature is also presented.
