ABSTRACT
Lumbar epidural steroid injections (LESIs) are commonly used for managing lower back pain (LBP) and radicular pain. LESIs are generally considered safe with only rare serious complication. One very rare complication that is frequently cited in the literature is adhesive arachnoiditis. However, a literature search failed to detect even one published manuscript, clearly documenting LESI induced arachnoiditis. This article presents two patients who received a transforaminal L5-S1 and two L3-L4 interlaminar LESIs. Although the presented patients developed clear radiological (MRI) findings of arachnoiditis, they were not accompanied by any improvement or deterioration in their clinical condition. The article also reviews the literature on the prevalence, pathogenesis, diagnosis, and clinical features of adhesive arachnoiditis. Literature suggests that adhesive arachnoiditis following LESIs is a rare entity, which - as seen in our patients - has clear radiological characteristics but uncertain pathogenesis. It has a large spectrum of clinical presentation, ranging from an incidental finding to a serious neurological sequela. In at least some patients with adhesive arachnoiditis following LESI, the radiological and clinical findings may fail to correlate with each other. In light of the fact that LESI is one of the most commonly performed procedures for managing LBP, clinicians should be aware of this rare yet existing entity.
ABSTRACT
BACKGROUND: The surgical treatment for liver tumors, whether metastatic or hepatic in origin, traditionally used the open approach through large incisions. In recent years the laparoscopic approach became popular but few centers use this method routinely. OBJECTIVES: To assess the results of our initial experience with liver resection using the laparoscopic approach, in terms of patient safety and oncologic surgical outcome. METHODS: Between August 2007 and April 2008 we performed 10 liver resections in 9 patients using the hand-assisted laparoscopic surgery technique. RESULTS: The main indication for surgery was metastatic colorectal carcinoma in seven patients and hepatocellular carcinoma in two. The mean age was 67 +/- 11 years. The tumor was solitary in seven patients. Five patients had neoadjuvant chemotherapy. Altogether, 12 lesions with an average size of 17 +/- 9 mm were resected. The mean operative time was 180 +/- 52 minutes. Average postoperative stay was 6.5 +/- 3.5 days. There was no perioperative mortality. There was one conversion to open surgery due to bleeding from the left hepatic vein. No major perioperative complications were encountered. All resected margins were free of malignancy. CONCLUSIONS: Liver resection using HALS is safe and feasible and should be considered in selected patients.
