应用吻合器行中、下段直肠癌切除术后吻合口漏──附10例报告

我科自１９８１年３月至１９９１年１２月应用吻合器行中、下段直肠癌切除术６７例，同期发生吻合口漏１０例（１４９％）。本文分析了吻合口漏发生的因素。病变部位、病灶范围、术中操作技术、术前肠道灌洗以及术后骶前引流是影响吻合口漏的重要因素。本文总结了吻合口漏的治疗方法，提倡保守治疗，或加作暂时性横结肠造口术。     

An improved method of flexible endoscopic creation of tracheoesophageal fistula for voice restoration

We present improvements of a previously reported method of tracheoesophageal puncture for voice restoration in postlaryngectomy patients. Our method utilizes a flexible endoscope to enable the tracheoesophageal puncture to be made under direct visualization using only local anesthesia and intravenous sedation. After 3 days, the created tracheoesophageal fistula tract is mature enough to allow placement of a voice prosthesis in the office. This allows the entire procedure to be performed in an outpatient setting with minimal risk. Received: 24 October 1996/Accepted: 24 January 1997     

Ectopic cervical salivary glands

Summary Ectopic salivary glands in the neck are very unusual lesions. Generally they are localized to the oropharyngeal region, near the mandible and para-parotid lymph nodes. They occur occasionally on the anterior border of the sternocleidomastoid muscle in the soft tissues of the neck. We wish to report on a singular association of ectopic salivary glands with partial hearing loss, preauricular fistula, palatoschisis, anal fistula, and an arteria lusoria. Morphological, histological and embryological aspects are discussed.

Recognition and management of patients with high-risk vesicovaginal fistulas: Implications for teaching and research

Vesicovaginal fistulas (VVFs) occurring as a result of obstetric trauma are a vast problem in Nigeria and Ghana, where at least 20 000 women await repair, and fewer than 50 physicians have the necessary expertise. Through a series of conferences those VVFs that are at high risk and those at low-risk for repair failure, were identified. A clinic was established where repair of low-risk VVFs was done on an ongoing basis in a remote region of Ghana. A visiting surgical team was utilized to repair the difficult, or high-risk, VVFs, which included 4–6 cm VVFs (3), recurrent VVF (1), combined VVF and RVF (rectovaginal fistula), a large 5 cm juxtacervical VVF (1), and a vesicouterine fistula (1). Management of these patients and others with VVF repair complications is discussed.     

TOTAL LARYNGECTOMY WITH PRIMARY VOICE RESTORATION

Forty-three patients were prospectively studied following tracheo-oesophageal puncture at the time of laryngectomy (primary voice restoration). Blom-Singer voice prostheses were used. The surgery was regarded as successful if a patient continued to use the voice prosthesis as the major means of communication with clear intelligibility 4 months after the operation. Using this criterion, the success in this series was 70%. No attempt was made to assess the quality of speech. Complications and causes of failure are discussed.     

Effects of N-acetyl-L-cysteine on Teratogenicity of Cadmium in Mice

ABSTRACT Embryotoxicity and teratogenicity of cadmium (Cd) and modulation of its effects by N-acetyl-L-cysteine (NAC) were evaluated in mice. Pregnant ICR mice were intraperitoneally injected with 3.5 mg/kg of CdCl₂ on day 10 or 11 of gestation (vaginal plug = day 0). Pregnant mice were pretreated with 160 mg/kg of NAC intravenously 2 hours before dosing with CdCl₂. Pregnant mice were killed on day 17 of gestation. Fetuses were examined for external malformations, especially limb malformations, cleft palate and abnormal palatal rugae. There was little difference in body weight gain of dams during the gestation period in the groups treated with NAC plus Cd as compared with the groups treated with Cd alone. Pretreatment with 160 mg/kg of NAC decreased the fetal mortality, incidence of cleft palate and abnormal palatal rugae induced by Cd on day 11. On day 10, pretreatment with NAC decreased the incidence of Cd induced abnormal palatal rugae. These results clearly indicate that NAC exerts protective effects against embryotoxicity and teratogenicity of Cd.     

Unusual CT and MRI findings in palatal myoclonus

A 23-year-old man suffered from palatal myoclonus for 2 years. It had appeared one week after a minor head trauma. MRI and basal cisternography revealed a localized atrophy of the left paramedian part of the medulla, encroached upon the left vertebral artery. Clonazepam treatment was beneficial. This particular case is discussed in relation to etiopathogenesis and other causes of palatal myoclonus.     

经未显影的岩下窦途径栓塞海绵窦区硬脑膜动静脉瘘

目的探讨经未显影的岩下窦途径栓塞海绵窦区硬脑膜动静脉瘘(CSDAF)的治疗方法。方法回顾性分析7例CSDAF病人的临床资料,均经未显影的岩下窦插管,以微弹簧圈栓塞海绵窦和瘘口。结果5例插管成功并达到完全致密栓塞;2例导管虽插入海绵窦,但海绵窦分隔致导管位置与瘘口不相通,而改行面静脉-眼静脉途径插管行栓塞治疗。7例病人均治愈,随访5～20个月,均无复发。结论经岩下窦途径栓塞是CSDAF最常用的治疗方法,即使岩下窦未显影,也有相当部分病人可插管和治疗成功。     

Sentinel Bleeding After Pancreaticoduodenectomy: A Disregarded Sign

Introduction Delayed massive hemorrhage induced by pancreatic fistula after pancreaticoduodenectomy is a rare but life-threatening complication. The purpose of this study was to analyze the clinical course of patients with late hemorrhage, with or without sentinel bleeding, to better define treatment options in the future. Material and Methods From April 1998 to December 2006, 189 pancreaticoduodenectomies were performed. Eleven patients, including two patients referred from other hospitals, were treated with delayed massive hemorrhage occurring 5 days or more after pancreaticoduodenectomy. Sentinel bleeding was defined as minor blood loss via surgical drains or the gastrointestinal tract with an asymptomatic interval until development of hemorrhagic shock. The clinical data of patients with bleeding episodes were analyzed retrospectively. Results Eight of the 11 patients had sentinel bleeding, and seven of them had it at least 6 h before acute deterioration. Seven out of 11 patients died, five out of eight with sentinel bleeding. No differences could be detected between patients with or without sentinel bleeding before delayed massive hemorrhage. The only difference found was that non-surviving patients were significantly older than surviving patients. Delayed massive hemorrhage is a common cause of death after pancreaticoduodenostomy complicated by pancreatic fistula formation. The observation of sentinel bleeding should lead to emergency angiography and dependent from the result to emergency relaparotomy to increase the likelihood of survival.
