AIM: To examine the allegations in malpractice litigations related to gastrointestinal endoscopy in Japan. METHODS: A retrospective review of cases tried in the civil court system during the 21-year period from 1985 to 2005, identified in a computerized legal database, was undertaken. RESULTS: Eighteen malpractice litigations and a total of 30 allegations were identified. Of the 18 (44%) malpractice litigations, 8 (44%) were related to esophagogastroduodenoscopy, 4 (22%) to colonoscopy, 4 (22%) to endoscopic sphincterotomy, and 2 (11%) to endoscopic retrograde cholangiopancreatography. Seventeen (94%) cases pertained to complications, and the remaining (6%) case pertained to misdiagnosis. In 10 cases, the patient died of the complications. Allegations were categorized as: (1) performance error during the endoscopic procedure (n = 12, 40%); (2) lack of informed consent (n = 9, 30%); (3) performance error during the treatment after the endoscopic procedure (n = 4, 13%); (4) premedication error (n = 3, 10%); (5) diagnostic error (n = 1, 3%); and (6) indication error for the endoscopic procedure (n = 1, 3%). CONCLUSION: These data may aid in the design of risk prevention strategies to be used by gastrointestinal endoscopists.
The purpose of this review was to examine a remarkable technical advance regarding the indications for and the technique of endoscopic resection of early gastric cancer. Endoscopic mucosal resection (EMR) of early gastric cancer with no risk of lymph node metastasis has been a standard technique in Japan, probably owing to the high incidence of gastric cancer in Japan and the fact that more than half of Japanese gastric cancer cases are diagnosed at an early stage. Very recently, several EMR techniques have become increasingly accepted and regularly used in Western countries. Although these minimally invasive techniques are safe, convenient, and efficacious, they are unsuitable for large lesions in particular. Difficulty in correctly assessing the depth of tumor invasion and an increase in local recurrence when standard EMR procedures are used have been reported in cases of large lesions, because such lesions are often resected piecemeal owing to the technical limitations of standard EMR. A new development in therapeutic endoscopy, called endoscopic submucosal dissection (ESD), allows the direct dissection of the submucosa, and large lesions can be resected en bloc. ESD is not limited by resection size and is expected to replace surgical resection. However, it is still associated with a higher incidence of complications than standard EMR procedures and requires a high level of endoscopic skill. The endoscopic indications, techniques, and management of complications of ESD for early gastric cancer for properly carrying out established therapeutic endoscopy are described.
The high prevalence of gastroesophageal reflux disease (GERD) in Western societies has accelerated the need for new modalities of treatment. Currently, medical and surgical therapies are widely accepted among patients and physicians. The minimally invasive treatment revolution, however, has stimulated several new endoscopic techniques for GERD. Up to now, the data is limited and further studies are necessary to compare the advantages and disadvantages of the various endoscopic techniques to medical and laparoscopic management of GERD. This systematic review reports the efficacy and durability of various endoscopic therapies for GERD whilst the potential for widespread use of these techniques is also discussed. Despite the limited number of studies and remarkable differences between various trials, strict criteria were used for the pooled data presented and an effort was made to avoid bias by including only studies that used off-antisecretory medication scoring as baseline and intent to treat.
