1/55. Epidural hematoma following epidural catheter placement in a patient with chronic renal failure.

    PURPOSE: We report a case of epidural hematoma in a surgical patient with chronic renal failure who received an epidural catheter for postoperative analgesia. Symptoms of epidural hematoma occurred about 60 hr after epidural catheter placement. CLINICAL FEATURES: A 58-yr-old woman with a history of chronic renal failure was admitted for elective abdominal cancer surgery. Preoperative laboratory values revealed anemia, hematocrit 26%, and normal platelet, PT and PTT values. General anesthesia was administered for surgery, along with epidural catheter placement for postoperative analgesia. Following uneventful surgery, the patient completed an uneventful postoperative course for 48 hr. Then, the onset of severe low back pain, accompanied by motor and sensory deficits in the lower extremities, alerted the anesthesia team to the development of an epidural hematoma extending from T12 to L2 with spinal cord compression. Emergency decompressive laminectomy resulted in recovery of moderate neurologic function. CONCLUSIONS: We report the first case of epidural hematoma formation in a surgical patient with chronic renal failure (CRF) and epidural postoperative analgesia. The only risk factor for the development of epidural hematoma was a history of CRF High-risk patients should be monitored closely for early signs of cord compression such as severe back pain, motor or sensory deficits. An opioid or opioid/local anesthetic epidural solution, rather than local anesthetic infusion alone, may allow continuous monitoring of neurological function and be a prudent choice in high-risk patients. If spinal hematoma is suspected, immediate MRI or CT scan should be done and decompressive laminectomy performed without delay.

2/55. Duodenal perforations after laparoscopic cholecystectomy.

    Duodenal perforations after laparoscopic cholecystectomies are rarely reported. The aim of this study is to focus on this complication and to suggest ways to reduce its occurrence and avoid diagnostic mistakes and therapeutical delays that could be fatal. We reviewed four personal cases and a number of others reported in the literature. Duodenal perforations are caused by improper use of the irrigator-aspirator device when retracting the duodenum, or by electrosurgical and laser burns. A duodenal perforation should be suspected in cases of bile leakage, peritonitis, intraabdominal or retroperitoneal collections, high serum or drainage amylase concentration, absence of bile leakage from the biliary tree, and the existence of a retroduodenal mass. Diagnosis requires a gastrografin upper GI series. Differential diagnosis is mainly with biliary lesions and other causes of peritonitis. Relaparoscopy may require intraoperative upper GI endoscopy or Kocher's duodenal mobilization to detect the perforation. early diagnosis allows primary repair, usually by laparoscopy. Perforations of the duodenal cap are easier to diagnose and have a better prognosis than those of the descending duodenum. A lumbar abscess is a frequent complication.

3/55. Delayed presentation of splenic rupture after colonoscopy.

    splenic rupture is a rare but potentially deadly complication of colonoscopy. We present the case of a 70-year-old male who presented with abdominal pain, initially stable, almost 2 days after colonoscopy. The patient's clinical status deteriorated shortly after abdominal CT scan identified splenic rupture.

4/55. Anaesthetic management for a left pneumonectomy in a child with bronchopleural fistula.

    The anaesthetic management of a left pneumonectomy in a 18-month-old girl with a bronchopleural fistula is described. An ordinary tracheal tube was slit at the bevel to ensure upper lobe ventilation on right endobronchial intubation. A combination of a bronchial blocker, endobronchial intubation with a slit tube, and nerve blocks for these manoeuvres was used. Pain relief by a thoracic epidural block ensured good physiotherapy and a comfortable postoperative period.

6/55. Late operative site pain with isola posterior instrumentation requiring implant removal: infection or metal reaction?

    OBJECTIVES: To elucidate the cause of late operative site pain in six cases of scoliosis managed with Isola posterior instrumentation that required removal of the implants. METHOD: Microbiologic examination of wound swabs and enriched culture of operative tissue specimens was undertaken in all cases. Histologic study of the peri-implant membranes also was conducted. RESULTS: The presentation in all cases was similar: back pain appearing between 12-20 months after surgery, followed by a local wound swelling leading to a wound sinus. In only one of these cases was the discharge positive for bacterial growth. Implant removal was curative. Histologic examination of tissue specimens revealed a neutrophil-rich granulation tissue reaction suggestive of an infective etiology despite the failure to isolate organisms. Within the granulation tissue was metallic debris that varied from very sparse to abundant from fretting at the distal cross-connector junctions. A review of recent literature describing similar problems suggests that late onset spinal pain is a real entity and a major cause of implant removal. CONCLUSIONS: On reviewing the evidence for an infective etiology versus a metallurgic reaction etiology for these cases of late onset spinal pain, it was concluded that a subacute low-grade implant infection was the main cause. Histologic findings would seem to confirm low-grade infection. There may be more than one causative factor for late operative site pain, as it is possible that fretting at cross connection junctions may provide the environment for the incubation of dormant or inactive microbes.

7/55. Acellular dermal matrix allograft in the treatment of mucogingival defects in children: illustrative case report.

    Mucogingival defects can occur in children and are of particular concern when orthodontic treatment is indicated. The rationale for surgical intervention is predicated on the need to repair the mucogingival defect and to establish adequate thickness of attached gingiva. The free gingival graft, usually obtained from the hard palate, is often used to increase the amount of attached gingiva. The prospect of a second surgical site, and its inherent risks and complications, which may include pain, discomfort, and bleeding, is especially undesirable in children. Important to consider is the possibility that a child may not have adequate tissue thickness at the donor site. A case report is presented utilizing the alternative soft tissue graft, Alloderm, to correct a mucogingival defect prior to orthodontic treatment. Adhering to the free gingival autograft technique, an acellular dermal matrix allograft was utilized at the graft site. The patient revealed good post-operative healing, tissue vascularization, and a healthy zone of attached gingiva at the six month follow up visit. Comparable results to the conventional autograft were obtained with less surgical time, surgical sites, and discomfort to the patient.

8/55. Repeated failure of epidural analgesia: an association with epidural fat?

    BACKGROUND AND OBJECTIVES: To report the case of a patient who experienced repeated failed epidural analgesia associated with an unusual amount of fat in the epidural space (epidural lipomatosis). CASE REPORT: A 44-year-old female presented for an elective small bowel resection. An L(1-2) epidural catheter was placed for postoperative analgesia. The patient gave no indication of having pain at the time of emergence from general anesthesia or in the first 2 hours in the recovery room. Assessment of the level of hypoesthesia to ice while the patient was comfortable in the recovery room suggested a functional epidural catheter (cephalad level of T(10)). Two hours after admission to the recovery room the patient began to complain of increasing pain. Another 6 mL 0.25% bupivacaine was administered via the catheter. The patient's pain decreased, but remained substantial, and there was minimal evidence of sensory block above the T(10) level. Subsequently, a T(10) epidural catheter was placed. Testing confirmed proper placement of the catheter in the epidural space at the T(10) level. A test dose of 5 mL 0.25% bupivacaine resulted in prompt and complete relief of the patient's pain. However, the level of hypoesthesia to ice did not exceed the T(10) level. Approximately 1 hour later the patient complained of increasing discomfort again. There was no evidence of any sensory block, and there was no response to a bolus of 8 mL 1% lidocaine. A thorough examination of the patient did not suggest any cause for the pain other than a malfunctioning epidural catheter. A third epidural catheter was placed at the T(8-9) level. This catheter was again confirmed to be in the epidural space with a test dose of 10 mL 0.5% bupivacaine. The level of hypoesthesia to ice was restricted to a narrow bilateral band from T(7)-T(9). analgesia failed 2 hours later. The epidural catheter was removed and the patient's pain was subsequently managed with intravenous patient-controlled analgesia (PCA) morphine. A magnetic resonance imaging (MRI) scan revealed extensive epidural fat dorsal to the spinal cord from C(5)-C(7) and from T(3)-T(9). An imaging diagnosis of asymptomatic epidural lipomatosis was established. CONCLUSION: We have described a case of repeated failure of epidural analgesia in a patient with epidural lipomatosis.

9/55. Rapid communication: laparoscopic Anderson-Hynes dismembered pyeloplasty using the da Vinci robot: technical considerations.

    PURPOSE: To present our initial experience with laparoscopic pyeloplasty utilizing the da Vinci robot for upper tract reconstruction. Case Report: A four-port transperitoneal approach was used in a 73-year-old man. The ureteropelvic (UPJ) obstruction was identified with a crossing vessel. After dismemberment of the UPJ, the renal pelvis was trimmed and reconstructed using the da Vinci robot. The total operative time was 5 hours; the time spent for reconstruction was 45 minutes. blood loss was <150 mL. The postoperative analgesic requirement was 8 mg of morphine and 25 mg of hydrocodone. There were no intraoperative or postoperative complications. CONCLUSION: The da Vinci robot can serve as a vital surgical tool during pyeloplasty with extensive reconstruction.

10/55. hemolysis caused by G-6PD deficiency after a difficult and prolonged therapeutic endoscopic retrograde cholangiopancreatography.

    Endoscopic retrograde cholangiopancreatography (ERCP), together with its substantial therapeutic capabilities, carries a higher potential for complications than other endoscopic procedures. Common major complications specific to pancreaticobiliary instrumentation include pancreatitis, post-sphincterotomy hemorrhage, perforation, and cholangitis with or without systemic sepsis. Two patients underwent therapeutic ERCP for recurrent episodes of abdominal pain and elevation of hepatobiliary enzymes. Endoscopic sphincterotomy was difficult and prolonged. The calculi were successfully extracted by sweeping the choledochus with a balloon-tipped catheter or basket in both cases. The patients experienced postprocedure diffuse abdominal pain unassociated with nausea or vomiting. Laboratory data showed normal serum amylase and lipase 2, 6, and 18 h after the end of procedure, a fall in hematocrit level, and an increase of indirect bilirubin and lactic dehydrogenase. The abdominal pain subsided in 4 to 6 h. The hematocrit level remained stable during the next 3 days, and the patients were very well when discharged. Examination of glucose-6-phosphate dehydrogenase (G-6PD) enzyme levels in red cells 20 days later showed complete enzyme deficiency. This report highlights the importance of examining G-6PD deficiency in patients with post-ERCP abdominal pain, normal serum amylase and lipase, and laboratory findings of hemolysis.
