Catheter Tip Granuloma Associated with Sacral Region Intrathecal Drug Administration

NEUROMODULATION, Issue 4 2003
Fernandez Julius MD
Abstract Spinal cord compression from catheter tip granulomatous masses following intrathecal drug administration may produce devastating permanent neurologic deficits. Some authors have advocated intrathecal catheter placement below the conus medullaris to avoid the possibility of spinal cord involvement. Multiple cases of catheter tip granulomas in the thoracolumbar region have been reported. We present a unique case of a sacral region catheter tip inflammatory mass producing permanent neurologic deficits. A 71-year-old white male with a diagnosis of failed back surgery syndrome was referred to the senior author for evaluation. After more extensive conservative therapy, including spinal cord stimulation, failed to yield adequate pain relief, he was offered implantation of an intrathecal pump for opioid administration. Excellent pain relief was achieved in the postoperative period; however, three years after implantation, he presented with progressive saddle anesthesia and bowel/bladder incontinence. Magnetic resonance imaging demonstrated a space occupying lesion associated with the catheter tip. The patient underwent emergent second level complete sacral laminectomy with partial resection of an intradural extra-axial mass and removal of intrathecal catheter. At discharge, the patient had no restoration of neurologic function. Histologic examination of the mass confirmed a sterile inflammatory mass. It has been suggested that intrathecal catheters be placed below the conus medullaris to avoid the possibility of spinal cord involvement. We present an unusual case documenting devastating permanent neurologic deficits from a catheter tip granuloma in the sacral region. [source]

Intrathecal Catheter Granuloma Associated with Continuous Sufentanil Infusion

PAIN MEDICINE, Issue 6 2010
Anita Gupta DO, PharmD
Abstract Intrathecal sufentanil is a minimally utilized opioid for patients with intractable pain refractory to traditional intrathecal medications. We present an 86-year-old female with a history of multiple spine surgeries who eventually progressed to having chronic, intractable, and diffuse low back pain. After failing medical management, she underwent a successful intrathecal trial of opioid therapy and was subsequently treated with an implantable drug delivery system (IDDS) or intrathecal pump. We describe the first reported case of formation of a catheter tip granuloma associated with intrathecal infusion of sufentanil. Due to increasing opioid requirements and gradually escalating pain, a computed tomography myelogram was performed to explore neuraxial etiologies of her symptoms. This investigation revealed the presence of a catheter tip-associated inflammatory mass (granuloma). All patients receiving intrathecal medications, including sufentanil, must be considered for the possibility of catheter-associated granuloma, particularly with symptoms of altered neurological function and/or increasing medication requirements associated with worsening pain.

Laparoscopic resection with transcolonic specimen extraction for ileocaecal Crohn's disease,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2010
E. J. Eshuis
Background: Ileocolic resection for Crohn's disease can be performed entirely laparoscopically. However, an incision is needed for specimen extraction. This prospective observational study assessed the feasibility of endoscopic transcolonic specimen removal. Methods: Endoscopic specimen removal was attempted in a consecutive series of ten patients scheduled for laparoscopic ileocolic resection. Primary outcomes were feasibility, operating time, reoperation rate, pain scores, morphine requirement and hospital stay. To assess applicability, outcomes were compared with previous data from patients who had laparoscopically assisted operations. Results: Transcolonic removal was successful in eight of ten patients; it was considered not feasible in two patients because the inflammatory mass was too large (7,8 cm). Median operating time was 208 min and median postoperative hospital stay was 5 days. After surgery two patients developed an intra-abdominal abscess, drained laparoscopically or percutaneously, and one patient had another site-specific infection. The operation took longer than conventional laparoscopy, with no benefits perceived by patients in terms of cosmesis or body image. Conclusion: Transcolonic removal of the specimen in ileocolic Crohn's disease is feasible in the absence of a large inflammatory mass but infection may be a problem. It is unclear whether the technique offers benefit compared with conventional laparoscopic surgery. Copyright © 2010 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

Intrathecal inflammatory masses: is the yearly opioid dose increase an early indicator?

NEUROMODULATION, Issue 2 2010
Rui V. Duarte BSc
Objectives:, The objective of this study is to investigate the association between intrathecal drug, flow rate, drug concentration, and drug dose with the formation of intrathecal inflammatory masses. Methods:, A retrospective longitudinal study of 56 consecutive patients receiving long-term intrathecal analgesic administration was undertaken through screening of medical records. Data regarding drug flow rate, dose per day, and concentration of drugs administered were recorded for morphine, diamorphine, bupivicaine, clonidine and baclofen and averages computed. Results:, The average follow-up time post-implant was 91 ± 55 months (range: 9,209). Four of the 56 patients were diagnosed with intrathecal granuloma indicating a rate of 7%, the equivalent to 0.009 events per patient year. Twenty-one of the patients had received morphine either alone or combined; 22 had received diamorphine either alone or mixed; and 13 crossed over from morphine to diamorphine or the inverse. None of the patients with granuloma crossed over before diagnosis. A significant correlation was found between opioid dose (r= 0.275, p < 0.05), yearly increase of the opioid dose (r= 0.433, p < 0.05), and granuloma formation. Clonidine appeared to have a protective effect for the non-granuloma patients. No association was found with flow rate (r= 0.056) or opioid concentration (r= 0.214). Conclusion:, This is the first detailed study showing an association of diamorphine with granulomas. This study supports the previous finding of intrathecal opioid dose being a risk factor for intrathecal granulomas and clonidine being protective. In addition we have found that the yearly increase in opioid dose is a risk factor for granulomas and could serve as an indicator for closer surveillance. [source]

Retroauricular Hairline Incision for Removal of Upper Neck Masses

THE LARYNGOSCOPE, Issue 12 2005
Jong-Lyel Roh MD
Abstract Background/Objectives: The general population has been increasingly concerned about cosmesis and hopeless about prominent or invisible postoperative scars of the face and neck. The purpose of this study was to evaluate the benefit of a retroauricular hairline incision (RAHI) by comparing it with conventional cervical incision for removal of upper neck masses. Study Design: Prospective clinical study. Methods: Thirty-four patients with upper neck masses were divided into two surgical groups of RAHI (17) and conventional cervical incision (17) matched by age, sex, marital status and size, location, pathology of lesions. The operation time, complications, length of hospital stay, and subjective satisfaction with incision scar checked by visual analogue scale were compared between groups. Results: The lesions of each group were congenital cysts (6), abscesses (2), inflammatory masses (2), and benign (6) or malignant (1) tumors and located in the upper neck. Mean operation time was 51 ± 17 minute in the RAHI group and 41 ± 13 minutes in the controls (P = .064). Mean hospital stay and complication rates were comparable between groups. Mean score of patient's satisfaction was 8.9 ± 0.7 in the RAHI group and 4.5 ± 2.7 in the controls (P < .001). The degree of incision scarring did not differ between groups, but the scars were less visible in the RAHI group because of hiding by the auricle and hair. Conclusions: The postauricular approach leading to a potentially invisible area of operation has a clear cosmetic benefit compared with conventional cervical incision. This will be helpful for patients with surgically indicated upper neck masses who hope for invisible incision scars. [source]
