Spontaneous CSF Leaks From the Temporal Bone

Spontaneous cerebrospinal fluid leaks from the temporal bone seem to be rare; however, increasing numbers of cases are being reported. This paper reports 14 cases. The presenting symptoms included hearing loss, external leaks, mass in the middle ear and external meatus, and facial paresis. All cases were evaluated with computed tomography (CT), eight with CT cisternography, and six with magnetic resonance imaging. In all patients the defect was found in the tegmen; in two, an additional defect could be detected in the posterior fossa. All were surgically treated by a transmastoid extradural technique. There are no recurrences after a mean follow-up period of 1.2 years (5 months to 2.4 years).     

Successful treatment of a patient with a 13-year history of post-traumatic rhinorrhea due to malabsorption of cerebrospinal fluid.

Chronic cerebrospinal fluid (CSF) leaks associated with skull base fractures are rare but intractable and patients may be subjected to numerous operations. We present a 30-year-old man with a 13-year history of chronic CSF rhinorrhea following a cranial trauma. Computed tomography (CT) showed a bone defect in the planum sphenoidale. CT cisternography revealed a leak from the defect and CSF malabsorption. The absence of symptoms of CSF malabsorption may be attributable to external leakage of excess CSF. After closing the leak via the extended transsphenoidal approach we placed a ventriculoperitoneal shunt for occult hydrocephalus. We discuss the clinical symptoms of chronic CSF leakage and present therapeutic strategies dictated by the mechanisms underlying the leak.     

BioGlue for prevention of postoperative cerebrospinal fluid leaks in transsphenoidal surgery: A case series

BACKGROUND: The efficacy of BioGlue (CryoLife, Inc, Atlanta, Ga) surgical adhesive in transsphenoidal surgery was assessed as an adjunct in the prevention of postoperative CSF leaks. METHODS: All patients in whom BioGlue was used for an intraoperative skull base reconstruction were retrospectively identified. Intraoperative CSF leaks were graded according to size (grade 1, small weeping leak without obvious diaphragmatic defect; grade 2, moderate leak with a definite diaphragmatic defect; grade 3, large diaphragmatic and/or dural defect). CSF leak repair was tailored to CSF leak grade. BioGlue was applied as a reinforcement over collagen sponge as the last layer of the repair. RESULTS: Over 28 months, a total of 282 patients underwent endonasal surgery. Of these patients, 124 (79 women; age range, 8-84 years), in 128 procedures, had an intraoperative CSF leak repair reinforced with BioGlue. Pathology included 80 pituitary adenomas, 11 craniopharyngiomas, 7 Rathke's cleft cysts, 6 chordomas, 5 meningiomas, 4 spontaneous CSF leaks, 3 arachnoid cysts, and 8 other parasellar pathologies. There were 62 (48.4%) grade 1, 41 (32.0%) grade 2, and 25 (19.5%) grade 3 leak repairs. The overall repair failure rate was 1.6% (2 cases), with the failures occurring in patients with grade 3 leaks, including 1 who developed meningitis; there was no failure of grades 1 and 2 leaks. The 2 failures were attributed largely to technical aspects of the repair rather than to failure of BioGlue per se. CONCLUSIONS: BioGlue appears to be an effective adjunct in preventing postoperative CSF leaks after transsphenoidal surgery. However, careful attention to technical details of the repair is still required to prevent failures, especially when closing large dural and diaphragmatic defects.     

Spontaneous cerebrospinal fluid leaks in congenital and acquired temporal bone defects-a long-term follow-up

Twelve patients presenting with tegmen defects and requiring surgical repair were retrospectively reviewed from 1982 to 1993. One half of the patients presented with a cerebrospinal fluid leak at some time in the course of their illness. Nine cases were considered to be acquired, secondary to previous mastoid surgery or trauma. All 9 had encephalocoeles. Three spontaneous leaks were considered congenital; 2 of these patients had encephalocoeles. This report represents a long-term follow-up of these cases, with an average follow-up of 7,6 years. Computed tomography and magnetic resonance imaging technology, as well as contrast studies, have tremendously aided in diagnosis and planning of surgical repair. Nine repairs were done through a dual transmastoid and middle fossa approach, with the other 3 done via a transmastoid approach only. We favored temporalis muscle flaps and temporalis fascia over synthetic materials for defect repairs. The long-term results and complications are discussed.

The significance and management of the leaking endograft.

Endoleak is the persistence of blood flow outside the lumen of an endograft, but within an aneurysm sac or adjacent vessel being treated by the graft. Diagnosis may be difficult, and treatment remains somewhat controversial. The purpose of this article is to discuss the clinical significance and appropriate management of endoleaks within the context of our current understanding of this phenomenon. The diagnosis of an endoleak can be made by conventional angiography, duplex ultrasound, intravascular ultrasound (IVUS), and computed tomography (CT) angiography. All of these modalities are effective, although CT angiography may be the most sensitive. Endoleaks can be categorized into 5 classes: (1) perigraft flow around the proximal end of the endograft; (2) perigraft flow around the distal end of the endograft; (3) flow through a defect in the body of the endograft; (4) flow between segments of a multicomponent endovascular graft; and (5) flow between arterial branches within an aneurysm sac. The first 4 classes have been shown to represent a clinical situation in which systemic arterial pressure is transmitted to an inadequately excluded aneurysm sac, placing the sac at risk of rupture. In contrast, branch-flow leaks do not appear to carry an increased risk of rupture, provided there is no increase in aneurysm sac diameter. However, an increase in the diameter of an aneurysm sac after endograft implantation may be a sign of occult endoleak, even if not visualized by current imaging techniques. Thus, we believe that collateral branch leaks with no associated aneurysm sac expansion may be observed with regular follow-up by CT angiography. All other endoleaks should be treated with adjunctive endovascular maneuvers or explanation of the endograft with standard open repair-in short, routine follow-up imaging on endografts to detect the presence of late endoleaks or aneurysm sac expansion.     

Prospective trial comparing contrast swallow,computed tomography and endoscopy to identify anastomotic leak following oesophagogastric surgery

Background Anastomotic leaks are a major complication of oesophagogastric surgery. We compare contrast swallow fluoroscopy, computed tomography (CT) with oral contrast and endoscopy in identifying anastomotic leaks following oesophagogastric surgery. Methods A prospective trial of 38 patients undergoing oesophagogastric resection was undertaken with informed consent and institutional review board (ethics committee) approval. Patients underwent all three investigations (over 24 hours) 1 week postoperatively. Results Eight (21%) had clinically apparent leaks. Three pseudo-leaks were suggested on contrast swallow but were confirmed normal on CT and endoscopy. Contrast swallow and CT missed one anastomotic leak each. Endoscopy identified anastomotic defects in three patients, in whom CT and contrast swallow were either normal or conflicting. Conclusions Routine tests of anastomotic integrity are unnecessary. When clinically suspected, contrast swallow or CT with oral contrast will identify most leaks. Endoscopy is useful in cases where there are incongruous results.     

Cerebrospinal fluid leaks from penetrating injuries: diagnosis and treatment

Penetrating Spinal Cord Injuries are often complicated by Cerebrospinal Fluid (CSF) leaks, which can be diagnosed either at initial presentation, or present themselves in a delayed fashion. Symptoms are usually non-specific and include positional headaches, nausea, vomiting, vertigo, and may even include hypotension, cranial nerve palsies, and in severe cases, meningitis. Imaging to detect CSF leaks include: plain radiographs, CT and MRI, CT-myelogram, radionuclide cisternograms, MRI with intrathecal gadolinium. Initial treatment of CSF leaks is conservative, including bedrest, hydration/overhydration, and medications such as caffeine and theophylline. Although overall treatment protocols are controversial, there seems to be a consensus that if a CSF leak persists for over 96 hours, it should be surgically treated, as it would inevitably increase the risks of pseudomeningocele formation and meningitis. Surgical options include a blood/fibrin patch, the placement of a lumbar drain, and ultimately surgical exploration and primary closure of the dural defect.     

Endoscopic endonasal approach for cerebrospinal fluid fistulae.

Different techniques have been proposed to repair cerebrospinal fluid rhinorrhea. Advances in nasal surgery led to a high success rate and low morbidity for the endonasal approach. It has become the favorite route for treating cerebrospinal fluid leaks of the anterior skull base. Better results have been obtained with the improvement of rigid endoscopes and intrathecal sodium fluorescein. In a prospective study, twenty-four patients with cerebrospinal fluid rhinorrhea were evaluated and treated by endoscopic endonasal surgery. In all cases intrathecal sodium fluorescein enabled a precise localization of the bone defect. The most common causes of CSF rhinorrhea were traumatic (8 cases, 33 %), spontaneous (6 cases, 25 %), and iatrogenic (5 cases, 20.8 %). Preoperative radiological evaluations (plane CT, CT cisternogram and MRI) showed the exact site and size of the defect in all patients. The most common site of leakage was the ethmoidal roof-cribriform plate. Primary closure was achieved in all patients. There were no major operative or postoperative complications. The endoscopic endonasal approach can be considered the first choice in the treatment of cerebrospinal fluid rhinorrhea.     

Efficacy of the over-the-scope clip (OTSC) for treatment of colorectal postsurgical leaks and fistulas

Background

Colorectal postsurgical leaks and fistulas are severe complications that dramatically increase morbidity and mortality. The aim of this study was to evaluate the clinical impact of over-the-scope clip (OTSC) closure to seal the visceral wall in the management of acute and chronic colorectal postsurgical leaks and fistulas.

Methods

We reviewed our prospective series of acute and chronic colorectal postsurgical leaks and fistulas observed between April 2008 and September 2011 and treated by OTSC. Indications were all cases with an orifice <15?mm in maximum diameter with no extraluminal abscess and luminal stenosis.

Results

Endoscopic OTSC closure was performed in 14 consecutive patients (mean defect?=?9.1?mm in diameter) by means of 10.5- or 12-mm clips, depending on the wall defect diameter. In eight cases, the indication was an acute leak and in six cases a chronic leak, mainly after anterior rectal resection; two cases were complicated by a rectovaginal fistula and in two other cases by a colocutaneous fistula. OTSC treatment was used to complete endoscopic vacuum-assisted closure of a large defect in three cases. The overall success rate was 86?% (12/14): 87?% (7/8) in acute and 83?% (5/6) in chronic cases. No OTSC-related complications occurred. Further surgery was required in one case.

Conclusion

Endoscopic OTSC closure of colorectal postsurgical leaks and fistulas is a safe technique, with a high success rate in both acute and chronic cases, including rectovaginal and colocutaneous fistulas.

Abstract：

Objective To explore surgical methods of repairing tibial skin defect using the anterolateral crural island flap.Methods The location,external diameters,anastomosis and distribution of perforators from the anterior tibial artery and the peroneal artery in the anterior septum were observed in 40 cadaveric specimens.Arterial angiography was performed in 4 fresh legs.Clinically,11 cases with tibial skin defect were repaired with the anterolateral crural island flap.There were 7 males and 4 females,with an average of 36 years (20-59 years).The area of the skin defect ranged from 6 cm×4 cm to 12 cm×4 cm.Results An arterial chain was formed by the interconnection of the superficial peroneal artery,the anterior septocutaneous perforator from distal part of the anterior tibial artery and the anterior end-perforator of the peroneal artery.It ran in the anterior septum and went along with the superficial peroneal nerve to supply blood to adjacent fascia and skin.The external diameters of the three perforators were (1.4±0.4) mm,(1.0±0.4) mm and (1.5±0.4) mm respectively,and the external diameter of the arterial chain was (0.6±0.2) mm.Clinically,we designed 4 methods to repair 11 cases of tibial skin defect successfully with the anterolateral cnnal island flap.The anterior septocutaneous perforator from distal part of the anterior tibial artery was used as pedicle in 2 cases;ascending branch of the anterior septocutaneous perforator from distal part of the anterior tibial artery was used as pedicle in 3 cases;descending branch of the anterior septocutaneous perforator from distalpart of the anterior tibial artery was used as pedicle in 3 cases;ascending branch of the anterior end-perforator of the peroneal artery was used as pedicle in 3 cases.The area of the flaps ranged between 7 cm×5 cm and 13 cm×5 cm.All patients were followed up with a mean time of 1.5 years.All flaps survived totally without diabrosis and swelling.Conclusion The anterolateral island flaps pedicled with perforators arising from the anterior septum of the lower leg is a good choice for surgeons to repair tibial skin defect.     

The Utility of Routine Postoperative Upper Gastrointestinal Swallow Studies Following Laparoscopic Sleeve Gastrectomy

Laparoscopic sleeve gastrectomy (LSG) has grown in popularity in recent years for the treatment of morbid obesity. Controversy exists regarding the usefulness of upper gastrointestinal (UGI) swallow studies on the first postoperative day in detecting possible complications. The aim of our study was to determine the efficacy and cost benefit of routine UGI studies on the first postoperative day following LSG. We retrospectively reviewed the hospital’s records to identify patients who underwent LSG between January 2012 and June 2013. All patients had iodine-based contrast swallow study on the first postoperative day. Reports from all imaging studies and medical files were retrospectively reviewed, and complications were recorded. The Institutional Review Board waived the requirement for informed consent. During the study period, 722 patients underwent LSG. Mean BMI was 43 kg/m² (range 25–70). Of the 722 UGI studies, 721 were normal. The 1 abnormal study showed complete obstruction due to an incarcerated hiatal hernia. Five patients presented with a leak (0.7 %). UGI swallow studies failed to detect any of the leaks resulting in a sensitivity of 0 %. All leaks were apparent on computed tomography (CT) scans on postoperative days 2, 5, 7, 23, and 90. The total cost of the UGI swallow studies was $180,500. Performing routine UGI studies on the first postoperative day following LSG is clearly not cost beneficial. UGI contrast studies are not efficient to screen for suture line leaks. We recommend obtaining a CT scan when there is clinical suspicion for a complication.     

Long-Term Follow-up Study of Biliary Reconstructions and Complications After Adult Living Donor Liver Transplantation: Feasibility of Duct-to-Duct Reconstruction With a T-Tube Stent

The aim of this study was to analyze the feasibility of duct-to-duct biliary reconstruction (hepaticohepaticostomy) with a T-tube stent (HH-T) after adult living donor liver transplantation (LDLT) based on long-term follow-up. We retrospectively evaluated 63 primary adult LDLTs who had survived >1 month from March 1999 to January 2008. We compared the incidence of bile leaks and biliary strictures (BS) in 3 groups of patients: Roux-en-Y hepaticojejunostomy (HJ; n = 18); duct-to-duct hepaticohepaticostomy with external stents except a T-tube (HH; n = 26); and HH-T (n = 19). Median follow-up was longer among the HJ (63 months) than the other groups (32 months in HH and 25 months in HH-T; P = .04). Bile leaks developed in 8 of the HJ cases (44%); 9 of the HH cases (33%); and 1 of the HH-T cases (5%; P = .02). All cases with bile leaks (n = 18) were treated using continuous drainage, 15 of them (83%) successfully. BS developed in 4 HJ cases (22%); 12 HH cases (46%), and 4 HH-T cases (21%; P = .12). Intervention for BS (n = 20) was successful in 10 cases (50%) via an endoscopic approach and 6 cases (30%) via a percutaneous transhepatic approach. Operative management for BS was required in 4 cases (20%). Biliary reconstruction using HH-T may be effective to prevent bile leaks after LDLT. However, HH-T may not decrease the incidence of BS after adult LDLT.     

Postoperative external alimentary tract fistulas.

Most series dealing with external gastrointestinal fistulas cover experience of many years and include a heterogeneous sample of fistulas. We present our experience with 117 cases of postoperative external alimentary tract fistulas treated since 1980. Only fistulas caused by anastomotic leaks and operative injury to bowel are included. The overall mortality rate was 37%. The fistulas are classified into four types: type I-abdominal, esophagus, gastroduodenal (mortality rate, 17%); type II-small bowel (mortality rate, 33%); type III-large bowel (mortality rate, 20%), and type IV-all sites associated with a large abdominal wall defect (mortality rate, 60%). The main cause of death was intra-abdominal infection. Seventy-six percent of the patients required further operations. We conclude that despite the availability of all modern diagnostic and management facilities, postoperative external gastrointestinal fistulas treated during the 1980s continue to represent a surgical "disaster." Only prevention and improved methods in the management of the associated intra-abdominal infections could improve the results.

目的应用外固定架结合皮瓣技术治疗合并软组织缺损的胫、腓骨骨折。方法应用单臂或环型外固定架固定胫骨骨折，根据小腿皮肤软组织损伤情况选用背阔肌皮瓣、股前外侧皮瓣、腓肠肌皮瓣、足背岛状皮瓣等8种不同皮瓣修复。结果临床应用30例，其中合并软组织缺损的胫、腓骨骨折急诊治疗16例、骨或钢板外露12例、骨不愈合及软组织瘢痕2例。经2年以上随访全部骨折均愈合，无感染发生。2例皮瓣出现小面积组织坏死，经换药后治愈，其余皮瓣成活良好。结论应用外固定架结合皮瓣技术是治疗合并软组织缺损的胫、腓骨骨折的有效方法。     

同种原位肝移植术的胆管重建及其术后并发症的防治

目的探讨同种原位肝移植(OLT)的胆管重建方式及其术后并发症的防治。方法回顾性分析1999年2月至2003年1月间103例终末期肝病患者施行OLT胆管重建及术后并发症的防治情况。103例患者中,75例采用经典式原位肝移植伴体外静脉转流、17例采用经典式原位肝移植不伴转流、11例采用背驮式原位肝移植。胆道重建过程中有94例行胆管端端吻合,9例行胆肠吻合。胆管端端吻合的患者中,62例带T管引流,32例不带T管,但11例经受者胆囊管置入小橡胶管引流。术后胆管并发症的诊断主要依据临床表现、B型超声波、磁共振胰胆管成像或逆行胰胆管造影检查。所有患者均随访1年以上。结果103例OLT患者术后胆管并发症发生率为7.8%(8/103)。62例带T管引流的患者中,6例(9.6%)发生胆管并发症,其中4例术后发生胆漏,2例拔除T管后发生局限性腹膜炎;32例不带T管引流的患者中,1例(3.1%)发生胆管狭窄。9例胆肠吻合中,1例(11.1%)术后发生胆漏。7例胆漏患者,2例经再次手术引流,其余继续保持引流胆漏自愈。不带T管引流的患者中的胆管狭窄为吻合口狭窄,经内镜取出异物、球囊扩张与安放内支架后治愈。1例患者因胆漏导致肝动脉吻合口假性动脉瘤及腹腔大出血,经介入法明确诊断并行栓塞治疗后治愈。患者中无胆管并发症而引起的死亡。结论胆管吻合口的胆漏与狭窄是OLT术后最常见的胆管并发症。良好的胆管血供与胆管吻合技术是防止胆管并发症发生的关键。及时的内镜检查与放射学技术是诊断和治疗胆管并发症的有效手段。     

Ilizarov外固定架治疗胫骨骨缺损及骨短缩

目的探讨应用Ilizarov外固定架治疗胫骨骨不连及骨缺损的方法及临床疗效。方法对19例胫骨骨不连及骨短缩患者（肢体短缩4~17cm,平均9cm）,根据Iuizarov治疗原则,采用微创截骨、直接拉伸延长或骨段滑移术修复骨缺损和延长肢体,在连续硬膜外麻醉下手术置入外固定架。骨不连者调整外固定架使骨断端对合并加压;骨缺损短缩者则做骨段搬移术或直接拉长。定期复查X片,直至骨愈合满意后拆除外固定架。结果本组术后经1～5年随访。所有骨缺损愈合,肢体长度恢复正常或接近正常,感染无复发。结论Ilizalov外固定架技术是治疗胫骨大段骨缺损的有效方法。软组织感染创面可在骨段滑移中逐渐缩小并闭合,骨感染可在骨段滑移中逐渐被控制并随骨连接而愈合。
