Regional anaesthesia and propofol sedation for carotid endarterectomy

ANZ JOURNAL OF SURGERY, Issue 7 2005
Christopher Barringer
Background: Many surgeons now perform carotid endarterectomy under regional anaesthesia. The aim of the present study was to review a sedation technique using a computer-controlled infusion of propofol. Methods: A consecutive series of 84 carotid endarterectomies done by a single surgeon and commenced under regional anaesthesia with sedation was studied. There were 54 men and 27 women (three bilateral procedures), with a median age of 71 years (range 48,87 years). All patients had carotid stenosis >70% 80 procedures were done for symptomatic disease and three asymptomatic patients were treated before cardiac surgery (one bilateral). Results: Seventy-seven procedures were completed under regional anaesthesia and sedation alone; seven required conversion to general anaesthetic, usually for intolerance of the operation. An intraoperative shunt was required on only four occasions (5%). Postoperatively eight patients required critical care monitoring, usually for blood pressure control. The remainder were nursed on the vascular ward, and 68% were discharged home on the day after surgery. No patient died, but there were two neurological complications. One patient had a cerebellar stroke 10 days after surgery, but recovered fully after 4 months. A second developed cerebral oedema due to severe intraoperative hypertension and required intensive care for 15 days. He too recovered fully. Five patients had a further episode of transient cerebral ischaemia within 1 month of operation, but in all cases duplex imaging showed a widely patent carotid and there were no sequelae. Conclusion: Target controlled propofol infusion is an effective method of sedation in patients undergoing carotid endarterectomy. [source]

Comparison of laparoscopic and open adrenalectomy for pheochromocytoma in a single center

ASIAN JOURNAL OF ENDOSCOPIC SURGERY, Issue 3 2010

Abstract Introduction: Laparoscopic adrenalectomy is recognized as a safe and feasible surgical procedure for removing adrenal masses, though some reports have questioned its use because of an increased risk of cardiovascular complications. This study aims to compare laparoscopic surgery and open surgery for pheochromocytoma. Methods: We analyzed 26 patients operated on for adrenal pheochromocytoma (laparoscopic surgery: 11 patients; open surgery: 15 patients) at Kyorin University Hospital from April 1995 to July 2009. Patient records were analyzed with regards to operative time, blood loss, complications, blood pressure during surgery, amount of analgesia required in patient-controlled analgesia, time to oral intake, length of hospital stay, and other factors. Results: Mean tumor size was greater in the open surgery patients. Blood loss was significantly less extensive in the laparoscopic surgery patients. Rates of intraoperative hypertension (defined as a sudden rise in systolic blood pressure of >200 mmHg) and hypotension (systolic blood pressure of <80 mmHg) immediately after clamping of the adrenal vein were significantly lower in the laparoscopic surgery patients. No significant differences were found between the two groups with respect to operative time, occurrence of complications, and analgesic requirements. Only one case (9.1%) required conversion from laparoscopic to open surgery because intraoperative complications, specifically uncontrollable hemorrhaging. Time to oral intake after surgery and hospital stay were significantly shorter in the laparoscopic surgery patients. During the follow-up period, there was no mortability or recurrence of endocrinopathy in the two groups. Conclusion: We consider the safety of laparoscopic adrenalectomy for pheochromocytoma to be similar to that of open surgery. [source]

Peri-operative complications of holmium laser enucleation of the prostate: experience in the first 280 patients, and a review of literature

BJU INTERNATIONAL, Issue 1 2007

OBJECTIVE To evaluate, in a prospective study, the complications in 280 patients undergoing holmium laser enucleation of the prostate (HoLEP) at our institution, and to review previous reports to determine the overall incidence and types of various complications, and analyse their causes and means of prevention. PATIENTS AND METHODS We analysed the patients' demographic, peri-operative and follow-up data, and the complications during and after surgery. RESULTS HoLEP was completed successfully in 268 patients (95.7%); eight required conversion to transurethral resection of the prostate (TURP) during the initial experience. The morcellation device and laser malfunctioned in two patients each. A blood transfusion was required during HoLEP in one patient; other complications included capsular perforation (9.6%), superficial bladder mucosal injury (3.9%) and ureteric orifice injury (2.1%). A blood transfusion was needed after HoLEP in 1.4% of patients and cystoscopy with clot evacuation in 0.7%. Transient urinary incontinence was the commonest complication after HoLEP, in 10.7% of patients, but recovered spontaneously in all except two (0.7%). Other rare complications were re-catheterization (3.9%), urinary tract infection (3.2%), epididymitis (0.7%), meatal and submeatal stenosis (2.5%), bulbar urethral stricture (2.1%), bladder neck contracture (0.35%) and myocardial infarction (0.35%). CONCLUSIONS There was a low incidence of complications with HoLEP; most were minor and easily managed. Our results are comparable with those published previously, and establish HoLEP as safe and reproducible procedure. While gaining experience, HoLEP can be converted to TURP with no harm to the patient. [source]

Routine use of laparoscopic repair for perforated peptic ulcer

Background: Laparoscopic repair of perforated peptic ulcer was reported in 1990 but has not gained wide acceptance. The aim of this study was to evaluate the safety and efficacy of laparoscopic repair for perforated peptic ulcer in routine clinical practice. Methods: This was a prospective analysis of 172 patients who underwent laparoscopic repair of a perforated peptic ulcer between July 1997 and June 2003. Results: One hundred and seventy-two patients of mean age 54 (range 14,93) years had perforated peptic ulcer diagnosed by laparoscopy. There were 172 duodenal ulcers, 22 prepyloric and 13 non-juxtapyloric gastric ulcers. One hundred and sixty-five patients underwent omental patch closure of perforations; there were six Pólya gastrectomies and one ulcerectomy. Thirty-seven patients (21·5 per cent) required conversion to laparotomy. The mean operating time was 64·8 (range 14,180) min. The median postoperative requirement for intramuscular pethidine was one dose. The median postoperative hospital stay was 6 days. Complications occurred in 28 patients (16·3 per cent) resulting in three reoperations. Six patients with intra-abdominal collections were managed by percutaneous drainage. Two patients who underwent conversion developed a wound infection. Fourteen patients (8·1 per cent) died, 11 of whom were American Society of Anesthesiologists grade III and IV. Conclusion: Laparoscopic repair of perforated peptic ulcer is a safe emergency procedure in routine clinical practice for patients with perforated pyloroduodenal ulcer.
