残胃癌临床诊治分析

目的分析和总结残胃癌的外科诊断、治疗及预后情况。方法对1990年以来收治的35例残胃癌的发病率、临床表现、治疗情况和预后进行回顾性分析。结果首次胃切除以胃溃疡为主,占65.7%,首次手术BillrothⅡ式占82.9%(29/35)。残胃癌早期缺乏特异的症状,主要为上腹部隐痛不适,首次手术距临床诊断残胃癌的间隔时间平均为16.3年。本组残胃癌手术切除率及根治性切除率分别为77.1%和54.3%,根治性切除患者1、3、5年生存率分为78.9%、52.6%、36.8%,Ⅰ期、Ⅱ期患者的5年生存率为72.7%。结论胃良性病行手术治疗时以BillrothⅠ式为首选,定期胃镜检查是早期诊断残胃癌的关键,根治性切除是治疗残胃癌的有效方法及影响残胃癌预后的重要因素。

Pericardial effusion following pulmonary resection

Objective Postoperative pericardial effusion commonly occurs after open heart surgery. However, after general thoracotomy such as pulmonary resection, there have been few reports of pericardial effusion. The purpose of this study is to investigate patients with pericardial effusion following pulmonary resection.Methods: Among 2,385 patients with pulmonary resection for lung neoplasm in our institute, eight patients, whose pericardium had never been opened during the operation, developed pericardial effusion. The clinical characteristics of the eight patients were analyzed.Results: Pericardial effusion after pulmonary resection was divided into two subtypes: pericardial effusion in three patients with left thoracotomy occurring within 30 days postoperatively, and pericardial effusion in the remaining five patients with right thoracotomy occurring more than 30 days postoperatively. Pericardiotomy or pericardiocentesis was performed in three symptomatic patients, and the remaining five asymptomatic patients were treated with diuretics. Pericardial effusion disappeared in three of the five patients about 1–3 months after the conservative treatment, while, in the remaining patients, because pericardial effusion had increased gradually, pericardiocentesis was performed.Conclusion: From our experience, the treatment strategy of drainage for early pericardial effusion and diuretics for late pericardial effusion seems to be appropriate.

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.     

输尿管口囊肿的微创手术治疗

目的评价输尿管口囊肿的微创手术治疗方法及其疗效。方法回顾性分析25例行经尿道电切（TURU）手术治疗输尿管口囊肿患者资料。男9例，女16例；年龄18—61岁，平均38岁；单侧18例，双侧7例；单纯输尿管囊肿22例，异位输尿管囊肿3例。结果25例患者手术一次成功22例，手术平均时间15min，术后平均住院3d。术后定期B超、膀胱造影随诊，随诊时间1—9年，3例异位输尿管囊肿合并重复肾、输尿管畸形患者存在术后膀胱输尿管返流，2例再次行开放手术后痊愈。结论TURU是治疗成人输尿管口囊肿的有效方法；当合并存在重复肾输尿管畸形或术后膀胱输尿管返流时，应采用输尿管膀胱抗返流手术。     

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.

Transurethral resection of a bladder tumor in pregnancy: A report of 2 cases

Carcinoma of the urinary bladder presenting during pregnancy is rare. We report two such cases presenting with gross hematuria, both of which were managed by transurethral electroresection of the tumor; there was no adverse effect on the pregnancies. Transurethral resection thus appears to be the procedure of choice in the management of this condition, and carries minimal morbidity even when performed during pregnancy. EDITORIAL COMMENT: As these authors point out, bladder tumors are rare in pregnancy and frequently present as gross hematuria that is mistaken for vaginal bleeding due to the pregnancy. Ultrasound is very helpful in distinguishing the causes of bleeding, and will show the bladder filled with clots and frequently the tumor as well. Standard transurethral resection is effective when performed during pregnancy, bearing in mind the need to heed to the anesthetic risks inherent in any operative procedure during pregnancy.
