Lesions of the lacrimal drainage system: a clinicopathological study of 643 biopsy specimens of the lacrimal drainage system in Denmark 1910-1999.

PURPOSE: To determine the frequency of histologically verified lesions of the lacrimal drainage system in Denmark between the years 1910 and 1999. Furthermore, to correlate the clinical diagnosis with the pathology diagnosis. METHODS: Retrospective review of all pathology reports from 1910 to 1999 in the files of the Eye Pathology Institute, University of Copenhagen, describing a lesion of the lacrimal drainage system. In addition, a retrospective review of all reports describing a lesion of the lacrimal drainage system from the Danish Pathology Database. All specimens were re-evaluated, except in cases with a primary diagnosis of dacryocystitis. In these cases a sample of 25% was re-evaluated. RESULTS: A total of 643 lesions were collected. Dacryocystitis was the most frequent lesion, constituting 508 cases (79%). The remaining cases were diagnosed as dacryolithiasis (62 cases; 7.9%), tumour (29 cases; 4.5%), trauma (19 cases; 3.0%), congenital malformation (nine cases; 1.4%), canaliculitis (eight cases; 1.2%) and granulomatous inflammation (eight cases; 1.2%). Seventeen tumours were malignant, of which B-cell lymphoma was the most common (six cases). In 0.6% of cases with a clinical diagnosis of dacryocystitis/lithiasis a non-suspected malignant tumour was diagnosed. Micro-organisms were uncommon in dacryocystitis (9%) but frequent in cases of dacryolithiasis (87%). CONCLUSION: Dacryocystitis was by far the most frequent lesion of the lacrimal drainage system referred for histopathological evaluation. Dacryolithiasis was often associated with micro-organisms, especially Gram positive rods. Histopathology is necessary to confirm suspected tumours, more than half of which were inflammatory lesions, and to detect tumours that sometimes masquerade as inflammation.

Successful paratopic pancreas transplantation: a report of three cases with venous portal drainage and enteric exocrine drainage.

Pancreatic transplantation is able to produce euglycemia in patients with Type I diabetes mellitus. Current surgical techniques utilize revascularization of the graft through the recipient iliac vessels and drainage of the exocrine pancreatic secretions through a duodenal conduit into the bladder. We describe a technique utilized in 3 patients whereby venous pancreatic drainage is into the portal venous circulation via the proximal splenic vein. The exocrine pancreatic secretions are drained into the proximal jejunum via a side-to-side donor duodenum to proximal small bowel anastomosis. Results and complications of this technique are presented. Potential short-term and long-term advantages and disadvantages of this technique are discussed. Our early experience suggests that paratopic pancreatic transplantation with venous drainage into the portal vein and exocrine drainage into the proximal jejunum is both feasible and desirable.

Percutaneous catheter drainage of liver abscess: an alternative to open drainage?

Percutaneous catheter drainage is still a new concept. Only 4 cases have been reported thus far and this paper reports 2 further cases. The technique of percutaneous catheterization of a liver abscess under CAT scan control is described, and the management of the catheter by a closed irrigation system is set out. Unless there is another compelling reason to do a laparotomy, we feel that this procedure is well worth a trial in view of the high mortality still associated with open drainage. Further experience may well prove percutaneous catheter drainage to be the procedure of choice for liver abscess.

Prospective randomized trial of drainage alone vs. drainage and fistulotomy for acute perianal abscesses with proven internal opening.

PURPOSE: Incision and drainage (I & D) with concurrent or delayed fistulotomy is the usual treatment for abscess-fistula with a demonstrated internal opening. We compared incision and drainage alone vs. with concurrent fistulotomy for perianal abscesses with a demonstrated internal opening. METHODS: Consecutive patients with acute perianal abscesses and a demonstrated internal opening were prospectively randomized into either the I & D group or drainage with concurrent fistulotomy group. They were followed up at one month, three months, and one year. RESULTS: The I & D group had 21 patients, and the fistulotomy group had 24 patients. Thirteen patients had low intersphincteric abscess-fistula, and seven had low transsphincteric fistulas in the I & D group. The fistulotomy group had 9 intersphincteric abscess-fistula compared with 14 low transsphincteric ones. Median duration of surgery, hospital stay, and continence at final follow-up were the same in the two groups. Three had recurrent abscess-fistula in the I & D group compared with none in the fistulotomy group (P = 0.09). CONCLUSION: I & D alone for acute anal abscess-fistula with demonstrated internal opening showed a tendency to recurrence that did not reach a statistically significant difference compared with concurrent fistulotomy. I & D, therefore, puts only a few patients at risk for recurrence.

Percutaneous transhepatic endobiliary drainage of hepatic hydatid cyst with rupture into the biliary system: an unusual route for drainage.

The most common and serious complication of hydatid cyst of the liver is rupture into the biliary tract causing obstructive jaundice, cholangitis and abscess. The traditional treatment of biliary-cystic fistula is surgery and recently endoscopic sphincterotomy. We report a case of complex heterogeneous cyst rupture into the biliary tract causing biliary obstruction in which the obstruction and cyst were treated successfully by percutaneous transhepatic endobiliary drainage. Our case is the second report of percutaneous transbiliary internal drainage of hydatid cyst with rupture into the biliary duct in which the puncture and drainage were not performed through the cyst cavity.

Randomized trial of drainage after cholecystectomy. Suction vaersus static drainage through a main wound versus a stab incision.

One hundred eighty-four patients who underwent biliary surgery were randomly allocated to four groups arranaed in a 2 by 2 design. In 92 patients the drain was brought out through the wound and in the other 92 through a stab incision. In half of the patients in each group the drain was connected to a suction system and in the other half to a sterile bag. Suction was found to impair rather than enhance intraperitoneal drainage. In patients who underwent elective cholecystectomy and early operation for acute cholecystitis, the amount of discharge was more than twice as large when suction was omitted than when it was applied. After common duct operations the amount of discharge was very large and there was little difference in cases with and without suction. Prolonged drainage, static or suction, resulted in an increase in the serum haptoglobin level. Analysis of out data suggested that after a few days the drain starts to act as a traumatic stimulus. No difference was found between cases with the drain brought out through a stab incision and those with the drain brought out through the main wound. A number of studies have ascertained the superiority of closed to open drainage. The results of the present trial lead us to recommend that after biliary surgery the closed us to recommend that after biliary surgery the closed drain should not be connected to a suction apparatus and that after elective cholecystectomy the drain should preferably be removed after a few days.

Drainage of hepatic, intraabdominal, and mediastinal abscesses guided by computerized axial tomography. Successful alternative to open drainage.

Opens surgical drainage of intraabdominal, intrahepatic, and mediastinal abscess is well established. Although this may be the procedure of choice when there are indications for treatment of concurrent intraabdominal and mediastinal surgical disease, with the advent of computerized axial tomography and ultrasonography we have identified a patient population best served by percutaneous catheter drainage. The procedure involves precise localization using ultrasound or CAT scanning, fine needle aspiration for confirmation of diagnosis, and injection of radiopaque contrast medium with fluoroscopic observation to localize the abscess. Catheter placement is usually achieved by a Seldinger technique, although a trochar-cannula method is occasionally required. Our experience with 4 patients, as well as review of the world literature provides a cumulative experience of 252 patients, has led us to believe that this approach is successful 83 percent of the time with a minimal incidence of complications. Percutaneous catheter drainage of intrahepatic, intraabdominal, and mediastinal abscess guided by computerized axial tomography is the treatment of choice in patients who do not have other indications for exploration.

Drainage of intraabdominal abscesses. A comparison of surgical and computerized tomography guided catheter drainage.

Over an 18 month period, 130 patients were sent to the radiology department for diagnostic CT scans to localize intraabdominal abscesses. Of these patients, 71 (55 percent) were diagnosed as having intraabdominal abscesses. Fifty-one surgical procedures and 17 radiologic drainage procedures were done. The cure rate of patients undergoing an operative procedure was 88 percent, and the major complication rate was 23 percent. The cure rate of patients undergoing CT guided catheter drainage was 47 percent and the complication rate was 6 percent. CT guided catheter drainage may be the initial treatment of choice in institutions that specialize in invasive procedures performed by radiologists. However, in institutions that have not concentrated their efforts on this problem, the results may not be as good, and it may not be wise to assume these data have general applicability. Greater cooperative efforts between departments of radiology and surgery should lead to better results in treatment of intraabdominal abscesses and better understanding of the best methods of treating them.

Biliary drainage: conversion of external to internal drainage.

A percutaneously inserted biliary drainage catheter was converted from external to internal drainage with the use of an additional catheter advanced through the gastrostomy opening. This technique was successful in one patient with unresectable cancer of the head of the pancreas, in whom it was performed to overcome the various disadvantages of external biliary drainage.

CT-Guided transgluteal drainage of deep pelvic abscesses in children: selective use as an alternative to transrectal drainage.

OBJECTIVE: The transgluteal approach to abscess drainage through the greater sciatic foramen has been described in adults, but this route has not been as extensively studied in children. We performed CT-guided transgluteal percutaneous abscess drainage in seven children and assessed the results of drainage and catheter tolerance. CONCLUSION: Transgluteal catheters are well tolerated by children, and the transgluteal route is an effective approach to selected pelvic abscesses in children.

[Technic of pleural drainage (emergency pleural drainage)].

Pleural effusion is still often poorly drained: - incorrect introduction of the drain into the thorax, - ill-chosen position of the drain. Simple drainage, a minima, is considered here, that which requires no broad surgical incision and which, in cases of effusion with compression of the lung, is often a life saving procedure which any doctor should be able to carry out, especially if he deals with emergencies. The surest technique consists of placing a No. 30 drain, using a pleurotomy trocart, type Monod or Coquelet, under local anaesthesia. Introduction of the drain using a forceps after an incision with the scalpel blade is only justified if one has no trocart available. So-called disposable drains, mounted on a pointed bevelled needle prepared in advance, are practical but dangerous. Capillary drainages are methods of second choice. They are often excluded within short delays. The efficacy of the drainage depends on its position.

[Slit drainage--progress in drainage treatment after herniotomy].

In a prospective randomized study was conducted on 80 patients undergoing elective hernia repair to assess whether a new slit-suction drainage is less painful than a Redon-suction drainage. Main endpoint of the study was the traction power in order to remove the drain. Other endpoints were pain at the time of removal of the drain and the effectiveness to draw off secretion. To remove redon drain the average traction power was 226 pond and to remove slit drain the average traction power was only 25 pond. The difference was significant (p less than 0.01). At the time of removal patients with slit drain rarely complained about pain (p less than 0.01). On contrary, patients with Redon drain always complained about pain. Clotting were seldom shown in slit drains and were frequently shown in redon drains. Both slit drains and redon drains were effective to drain secretion. As the new slit drain was more comfortable for patients following hernia repair slit drain should always be used as subcutaneous suction drainage.

Percutaneous catheter drainage for acute empyema. Improved cure rate using CAT scan, fluoroscopy, and pigtail drainage catheters.

Percutaneously inserted pigtail nephrostomy catheters were used to treat empyemas in 12 patients. Thoracic computed tomographic (CT) scan and fluoroscopy were used to localize precisely and place the catheters into loculated collections of fluid. Percutaneous catheter drainage (PCD) of empyema was successful in seven of seven patients (100%) in whom standard tube thoracostomy (STT) had initially failed and in three of five patients (60%) who had PCD as the initial drainage procedure. Overall, PCD was successful in treating empyema in ten of 12 patients (83%). The procedure was well tolerated and there were no complications. PCD is a safe and effective method for drainage of loculated empyemas as the initial procedure or after STT has failed.

Sump drainage versus static drainage after cholecystectomy.

Sump drainage was compared with closed static drainage in a randomized trial using a restricted sequential plan. Sump drains were converted into static drains by closing the air-vent tubes and by omitting suction. Sump drains so converted evacuated more intraperitoneal fluid during the first 24 hours after cholecystectomy than did drains in which the sump was functioning. For drainage after cholecystectomy, the sump drain is inferior to the passive drain in a closed circuit.

Laser-aided external drainage of subretinal fluid: prospective randomized comparison with needle drainage.

In a prospective randomized study of 50 consecutive eyes, we compared the safety and efficacy of draining subretinal fluid transchoroidally in primary scleral buckling for rhegmatogenous retinal detachment using a needle, with the safety and efficacy of the same procedure using an angulated endolaser probe set at 1 W for 0.2 seconds, using an average of 2.4 laser burns. There were no significant complications associated with the laser-aided drainage procedures (25 eyes). In the transchoroidal needle drainage procedures (25 eyes), subretinal hemorrhage occurred in three eyes and retinal incarceration in one. Thus, though our numbers are small, there appears to be some advantage of laser-assisted drainage in terms of a lower incidence of complications.

[Percutaneous bile drainage in neoplastic obstructive pathology of the biliary tract. Experience of the Hotel-Dieu of France in 100 drainages].

Between 1981 and 1994, a 100 biliary drainages were introduced transhepatically in 71 patients with malignant biliary disease. Eighty-six endoprosthesis were inserted, 6 internal-external drainages and 8 external drainages. Our success rate in catheterization of the stenosis was 97%. The early complication rate was 17% (12/71) most often due to hemorrhage (n = 3), infection (n = 4), duodenal perforation (n = 1), biliary leak (n = 2) and death by septic shock (n = 2). Twenty-nine patients with 39 endoprosthesis had a long-term follow-up. The most common late complication observed was occlusion (15/39, 37%) and migration (1/39, 2.5%). Specific treatment of complications was carried out in 10 of the 29 patients (35%). It is concluded that patients with inoperable malignant obstruction of the bile ducts should be offered an indwelling endoprosthesis whatever their prognosis; an occluded stent can be removed or at least bypassed in nearly all patients, thereby maintaining palliation of symptoms.

Managing selenium-contaminated agricultural drainage water by the integrated on-farm drainage management system: role of selenium volatilization.

The Integrated on-Farm Drainage Management (IFDM) system was designed to dispose of selenium (Se)-contaminated agricultural irrigation drainage water through the sequential reuse of saline drainage water to grow crops having different salt tolerance. This study quantified the extent of biological volatilization in Se removal from the IFDM system located in the western San Joaquin Valley, California. Selenium volatilization from selected treatment areas, including pickleweed (Salicornia bigelovii Torr.), saltgrass (Distichlis spicata L.), bare soil, and the solar evaporator, was monitored biweekly using an open-flow sampling chamber system during the pickleweed growing season from February to September 1997, and monthly from September 1997 to January 1998. Biological volatilization from the pickleweed section removed 62.0 +/- 3.6 mg Se m(-2) y(-1) to the atmosphere, which was 5.5-fold greater than the Se accumulated in pickleweed tissues (i.e., phytoextraction). The total Se removed by volatilization from the bare soil, saltgrass, and the solar evaporator was 16.7 +/- 1.1, 4.8 +/- 0.3, and 4.3 +/- 0.9mg Se m(-2) y(-1), respectively. Selenium removal by volatilization accounted for 6.5% of the annual total Se input (957.7mg Sem(-2) y(-1)) in the pickleweed field, and about 1% of the total Se input (432.7 mg Se m(-2) y(-1)) in the solar evaporator. We concluded that Se volatilization under naturally occurring field conditions represented a relatively minor, but environmentally important pathway of Se removal from the IFDM system.

[Studies on the lymph drainage of the eye. 1. Quantitative registration of the lymph drainage from the orbita of the rabbit with radioactive tracers (author's transl)].

For the investigation on the lymph drainage from the orbita 99mTc-microcolloid, 99mTc-albumin and 198Au-colloid have been injected into the retrobulbar space of 24 rabbits. Measurements of the activity's distribution have been made in vivo with an Anger type camera (pho-Gamma-IV Hp, Searle Nuclear Chicago) and in vitro after section with a sodium iodine crystal well counter (Clinimat-200, Picker). A significant concentration of the activity could be observed for the most part in the equilateral Lymphonoduli cervicales profundi and superficiales and for the less part also in the equilateral Lymphonoduli mandibulares and contralateral Lymphonoduli cervicales profoundi. Furthermore significant activities could be pointed out in the optic nerves as well as in the contralateral retrobulbar space. The data substantiate a lymph drainage from the orbita as well as a partly reverse "prelymphatic-lymphatic" flow and are of importance for discussions about lymphostatic ophthalmopathy and sympathetic ophthalmitis. For application on man 99mTc-microcolloid (Lymphoscint) shoud be preferred, because with this tracer 1. the lymph drainage can be measured quantitatively quite exactly by extern measurement with the Anger-camera, 2. the allowable radiation dosis for the lens is lying between 0.5-1.0 rad/mCi.
