小血管套叠粘接吻合法在血液透析者中建立动静脉内瘘的应用

慢性肾病患者常需要建立动静脉内瘘进行透析，常规间断缝合法吻合动静脉难度大、耗时长。为了缩短吻合时间，提高远期通畅率，进行了套叠粘接吻合法建立动静脉内瘘的实验研究，并将这一方法应用于透析患者建立动静脉内瘘的血管吻合。将动脉端套入静脉端，只需吻合两针，用医用胶封闭吻合口。经８个月观察，通畅率达１００％，血流量均超过３００ｍｌ／ｍｉｎ。达到了透析需要。     

A Rare Case of Biliobiliary Fistula

Abstract: Biliobiliary fistula is a rare clinical entity. The case of a 72 year old female, who presented with epigastric pain and jaundice, is detailed herein. Endoscopic retrograde cholangiopancreatography (ERCP) revealed two stones, one each in the common bile duct and the gallbladder. Continuous endoscopic nasobiliary drainage (ENBD) was performed to relieve obstructive jaundice. Further study with contrast medium administered via the ENBD tube revealed a fistula between the neck of the gallbladder and the common bile duct. The cystic duct was intact. A stone was considered to have migrated into the common bile duct through the fistula. A diagnosis of biliobiliary fistula, Corlette type I was made. However, in this particular case, a biliobiliary fistula was noted at a site below the junction of the cystic duct and common bile duct. Removal of the gallbladder stones was followed by cholecystectomy. The common bile duct was then repaired by utilizing a T-tube. No evidence of malignancy was recognized in the resected gallbladder specimen. In the one year to date since surgery, the patient has been asymptomatic and without signs of biliary disease.     

BILIARY HYPERPRESSURE IN RAT EXTRAHEPATIC CHOLESTASIS ALTERS HORSERADISH PEROXIDASE BILIARY EXCRETION

1. The authors investigated the effect of two extrahepatic cholestasis models (one by bile duct ligation and the other by choledocho-jugular fistula) on the hepatic clearance of horseradish peroxidase in male Sprague-Dawley rats divided into four groups. 2. In groups A (n = 5 rats) and B (n = 5), bile duct ligation was performed, while a choledocho-jugular fistula was created in groups C (n = 5) and D (n= 7). A 10 mg intravenous bolus of horseradish peroxidase was injected after 24 h (groups A and C), 48 h (groups B and D) or 1 h (Group E; five sham-operated rats). Serum and bile samples were then serially collected for 2 h. 3. In all groups, serum horseradish peroxidase levels increased soon after injection and then rapidly decreased, the curves being similar. Biliary excretion increased for 30 min and then slowly decreased. The highest horseradish peroxidase biliary concentrations and outputs were found in Group B followed by Group A; both groups had significantly higher levels than Group E. No difference was found between horseradish peroxidase biliary excretion of groups C and D and that of sham-operated rats. 4. When each group was considered separately, sampling times correlated with the corresponding ratios of bile/ plasma HRP. Significant differences were found between the relative slopes of groups A, B and E, but not between those of groups C, D and E. 5. In conclusion, bile duct obstruction greatly affects the plasma-bile transfer of fluid phase markers, such as horseradish peroxidase, while single retention, caused by choledocho-jugular fistula, has no influence. The increased biliary hyperpressure related to the duration of cholestasis may account for the degree of horseradish peroxidase transfer which, in turn, probably depends on an enhanced paracellular passage.     

Ileocutaneous fistula formation following laparoscopic polypropylene mesh hernia repair

A rare case of enterocutaneous fistula caused by chronic erosion of polypropylene mesh after laparoscopic repair of a recurrent inguinal hernia is described. Successful treatment was achieved by fistulectomy, total resection of the implanted mesh, and small-bowel segmental resection. The patient recovered well postoperatively, and at follow-up 18 months later, the herniorrhaphy has remained intact. This complication needs to be added to the differential diagnosis in patients who present inflammation, abscess formation, or cutaneous fistula following laparoscopic hernia repair.

A new operational approach for the piriform sinus fistula

It has been well documented that piriform sinus fistulae often cause suppurative thyroditis; however, when a piriform sinus fistula does not present this symptom, making a correct diagnosis is very difficult. We have experienced 11 cases of a piriform sinus fistula. The conventional operational approach was performed in the initial eight patients, among which there were four recurrences in two patients. Therefore, a new operational approach was introduced for the three most recent cases and one recurrent case. First, the existence of the internal orifice of the fistula is confirmed with a laryngoscope, after which a transverse incision on the neck is made and the abscess dissected. The side wall of the piriform sinus is then opened with the help of a laryngoscope and the bottom part of the mucosa of the sinus transected with the internal orifice of the fistula, after which the fistula is removed en bloc with the bottom part of the sinus and abscess cavity. Using this operation, we experienced no complications and there has been no recurrence so far.This paper was presented at the 23rd Annual Meeting of Pacific Association of Pediatric Surgeons, June 1990 in Kona, Hawaii.     

AN UNUSUAL CAUSE OF RECTOVAGINAL FISTULA

An unusual case of rectovaginal fistula is reported. An 81 year old woman presented to the geriatric team with a request to review her faecal incontinence. It was discovered that she had a predilection for placing foreign objects in her vagina. In this instance a carbonated drink top had formed a rectovaginal fistula.     

Vesicocutaneous fistula: An unusual complication of inguinoscrotal hernia

Involvement of the urinary bladder in an inguinal hernia is common, but massive bladder hernia is rare. Most urinary bladder herniations are discovered and repaired during surgery. We report a case of large incarcerated inguino-scrotal hernia, which was reduced only to present as a scrotal abscess and vesicocutaneous fistula; an unusual complication. The patient was managed conservatively due to underlying comorbidities.

Off-pump resection of a coronary arterial fistula using the Harmonic Scalpel

Off-pump surgery was performed in a patient with post-infarction angina complicated with aneurysmal coronary-pulmonary arterial fistula. Epicardial echocardiography localized the artery feeding the fistula in the myocardium, which had not been revealed by visual inspection, palpation, or transesophageal echocardiography. The patient underwent off-pump coronary artery bypass grafting concomitant with aneurysmectomy. The feeding arteries were dissected easily using a Harmonic Scalpel and ligated. The flow in the aneurysm disappeared immediately and aneurysmectomy was performed without bleeding.
