A 13-year experience with epilepsy surgery

Between 1985 and 1997, 563 therapeutic craniotomies were performed: 311 anterior temporal (ATL) and 158 extramesial temporal (XMT) resections, 67 callosotomies, 20 hemispherectomies and 7 multiple subpial transections. Sixty-seven percent of nonlesional ATL cases were seizure free (SF), and 76% of nonlesional ATL cases < or =18 years old were SF. Seventy-eight percent of lesional ATL cases with complete resection were SF. Seventy-three percent of lesional cases < or =18 were SF. Thirty-seven percent of nonlesional XMT cases were SF. Seventy percent of XMT lesional cases with complete resection were SF, and 82% of lesional XMT cases < or =18 were SF. Of the anterior callosotomy cases, there was a > or =90% decrease in generalized tonic-clonic seizures in 50% of patients, and in tonic seizures, drop attacks, absence and myoclonic seizures in approximately 60-70% of patients. Of 20 hemispherectomies, 65% were SF. Of 7 multiple subpial transections, 29% were SF.     

Minimally invasive surgery for achalasia: A 10-year experience

Minimally invasive esophagomyotomy for achalasia has become the preferred surgical treatment; the employment of a concomitant fundoplication with the myotomy is controversial. Here we report a retrospective analysis of 53 patients with achalasia treated with laparoscopic Heller myotomy; fundoplication was used in all patients except one, and 48 of the fundoplications were complete (floppy Nissen). There were no deaths or reoperations, and minor complications occurred in three patients. Good-to-excellent long-term results were obtained in 92% of the subjects (median follow-up 3 years). Two cases (4%) of persistent postoperative dysphagia were documented, one of which was treated with dilatation. Postoperative reflux occurred in five patients, four of whom did not receive a complete fundoplication; these patients were well controlled with medical therapy. We suggest that esophageal achalasia may be successfully treated with laparoscopic Heller myotomy and floppy Nissen fundoplication with an acceptable rate of postoperative dysphagia.

Dissociative anesthesia in ambulatory plastic surgery: A 10-year experience

The author describes extensive use of diazepam (Valium) with ketamine as a safe and efficacious technique of dissociative local anesthesia in an ambulatory plastic surgery facility. He finds these agents helpful in rhinoplasty, facial surgery, and breast augmentations as well as all other aesthetic and most reconstructive procedures.     

Initial experience with intraoperative magnetic resonance imaging in spine surgery

STUDY DESIGN: A case series of 12 patients who underwent spine surgery in an intraoperative magnetic resonance imager (IMRI). OBJECTIVES: To determine the advantages, limitations, and potential applications to spine surgery of the IMRI. SUMMARY OF BACKGROUND DATA: Existing stereotactic navigational systems are limited because images are obtained before surgery and are not updated to reflect intraoperative changes. In addition, they necessitate manual registration of fiducial landmarks on the patient's anatomy by the surgeon to the previously obtained image data set, which is a potential source of error. The IMRI eliminates these difficulties by using intraoperative acquisition of MRI images for surgical navigation with the capacity for both image update and image-guided frameless stereotaxy. The IMRI is a novel cryogenless superconducting magnet with an open configuration that allows the surgeon full access to the patient during surgery and intraoperative imaging. METHODS: T1- and T2-weighted fast spin echo images were obtained for localization, after surgical exposure and after decompression during the course of 12 spine surgeries performed in the IMRI. RESULTS: The authors performed a series of 12 procedures in the IMRI that included three lumbar discectomies, three anterior cervical discectomies with allograft fusion, three cervical vertebrectomies with allograft fusion, two cervical foraminotomies, and one decompressive cervical laminectomy. The system provided rapid and accurate localization in all cases. The adequacy of decompression by MRI during surgery was confirmed in 10 of 12 cases. CONCLUSIONS: The IMRI provided accurate and rapid localization in all cases and confirmed the adequacy of decompression in the majority of cases. Future applications of the IMRI to spine surgery may include intraoperative guidance for resection of spine and spinal cord tumors and trajectory planning for spinal endoscopy or screw fixation.     

Outcomes of cardiac surgery in nonagenarians: a 10-year experience

BACKGROUND: With an increasing awareness of health issues and greater emphasis on preventive medicine, the general population is living longer and healthier lives than ever before. Physicians are taking care of older patients, many of whom may require cardiac surgical procedures. Improving cardiopulmonary bypass technology allows for safer procedures with reduced morbidity and mortality even in older patients. METHODS: We have performed a retrospective analysis of 42 consecutive nonagenarian patients who underwent open-heart procedures over a 10-year period (1993 to 2002) at our institution. Their demographic profiles, operative data, perioperative results, and long-term outcomes were recorded and analyzed. RESULTS: Twenty-two women and 20 men with an age range of 90 to 97 years (mean, 91.4 years) had open-heart surgery over the study period. The complication rate was 67% overall, consisting of 7% respiratory (pneumonia, respiratory failure, reintubation), 7% hemorrhagic or embolic (postoperative bleeding, cerebral vascular accident), 12% infectious (wound infection, sepsis), and 31% new arrhythmia (atrial fibrillation, atrial flutter, ventricular tachycardia, ventricular fibrillation). Despite these complication rates, average hospital stay was 17.5 days (median, 11 days), with an intensive care unit stay of 12.0 days (median, 5 days). Thirty-day survival was 95% and survival to discharge was 93% (three deaths total; one cardiac arrest at hospital day 134 and two perioperative deaths; one ventricular arrhythmia, one cerebral vascular accident). The only statistically significant risk factor of mortality was emergency surgery. Currently, 81% are still alive an average of 2.53 years since surgery (range, 0.16 to 7.1 years). CONCLUSIONS: With improving techniques and greater attention to detail, the select nonagenarian can safely undergo cardiac surgery.     

Parenchymal sparing surgery in patients with hereditary renal cell carcinoma: 10-year experience

PURPOSE: von Hippel-Lindau disease, hereditary papillary renal cell carcinoma, the Birt-Hogg-Dubé syndrome and familial renal oncocytoma are familial renal tumor syndromes. These hereditary disorders are noteworthy for the development of multiple bilateral renal tumors and the risk of new tumors throughout life. One management strategy is observation of solid renal tumors until reaching 3 cm, then performing parenchymal sparing surgery. We present a 5-year update on our experience. MATERIALS AND METHODS: From May 1988 to October 1998, 49 patients with hereditary renal cell carcinoma, including von Hippel-Lindau disease in 44, hereditary papillary renal cell carcinoma in 4 and the Birt-Hogg-Dubé syndrome in 1, and 1 with familial renal oncocytoma underwent exploration to attempt renal parenchymal sparing surgery. Patients were followed prospectively with periodic screening for recurrence, metastasis and loss of renal function. Median followup was 79.5 months (range 0.7 to 205). RESULTS: A total of 50 patients underwent 71 operations resulting in unilateral nephrectomy in 6, bilateral nephrectomy in 1 and partial nephrectomy in 65, with 1 to 51 tumors removed from each kidney (mean 14.7). Mean patient age was 39.5 years (range 18 to 70). Of the 65 (40%) partial nephrectomies 26 were performed with cold renal ischemia. Mean blood loss was 2.9 +/- 0.5 l (range 0.15 to 23). Postoperative complications included renal atrophy in 3 patients. Mean preoperative serum creatinine was 1.05 +/- 0.03 mg/dl (range 0.6 to 1.8), and postoperative creatinine was 1.06 +/- 0.04 mg/dl (range 0.6 to 2.0). No patient who underwent renal parenchymal sparing surgery required renal replacement therapy. Metastatic disease developed in 1 patient with a 4.5 cm renal tumor. CONCLUSIONS: Parenchymal sparing surgery with a 3 cm threshold in patients with hereditary renal cancer appears to be an effective therapeutic option to maximize renal function while minimizing the risk of metastatic disease.     

A 10-year experience of complex liver trauma

BACKGROUND: Liver trauma is a relatively rare surgical emergency but mortality and morbidity rates remain significant. It is likely that surgeons outside specialist centres will have limited experience in its management; therefore best practice should be identified and a specialist approach developed. METHODS: Data collected from 52 consecutive patients over a 10-year interval were examined to identify best practice in the management of these injuries. RESULTS: The majority of injuries occurred as a result of road traffic accidents; 39 (75 per cent) of the 52 patients were stable at presentation to the referring hospital. In 36 patients (69 per cent) the liver injury was a component of multiple trauma. Ultrasonography, computed tomography or no radiological investigation was used in the referring hospital in 18 (35 per cent), 25 (48 per cent) and nine (17 per cent) patients respectively. Operative management was undertaken in the referring hospital in 26 patients (50 per cent). The overall mortality rate was 23 per cent (12 of 52 patients), and increased with increasing grade of severity. Eight of 26 patients managed surgically at the referring hospital died, compared with four of the 26 patients managed without operation (P not significant). The median time from arrival at the referring hospital to operation was 4 h for haemodynamically stable patients and 3 h for those who were haemodynamically unstable. CONCLUSION: Most patients with liver trauma can be managed conservatively. Operative management carried out in non-specialized units is associated with high mortality and morbidity rates. Abdominal injuries should raise a high index of suspicion of liver injury, and the data suggest that computed tomography of the abdomen should precede laparotomy (even in some haemodynamically unstable patients) to facilitate discussion with a specialist unit at the earliest opportunity.     

Trends in laparoscopic surgery for colorectal cancer: 10-year experience worldwide

Laparoscopic colorectal surgery was introduced in 1991 and has been performed around the world. We review the English literature on this technique, including reports of case series, case-control studies, and randomized controlled trials. These reports show that laparoscopic surgery for colorectal cancer is safe and useful and that the short-term results of this technique are acceptable and satisfactory. Port-site metastasis is rare in the more recent experience of skilled laparoscopic surgeons, and the survival rates of patients after laparoscopic surgery are comparable to those after conventional open procedures. In the near future, long-term results, including 5-year survival rates, will be clarified in randomized controlled trials comparing laparoscopic and open resections of colorectal cancer.     

Salvage surgery for locally recurrent nasopharyngeal carcinoma-A 10-year experience.

OBJECTIVE: To evaluate the result of salvage surgery for patients with primary recurrence of nasopharyngeal carcinoma (NPC) after radiation therapy. STUDY DESIGN AND SETTING: Prospective cohort at a tertiary referral center. PATIENTS AND METHODS: Thirty-eight consecutive patients with primary recurrence of NPC after radiation failure underwent salvage surgery for curative intention via the facial translocation approach from July 1993 to December 2002. The follow-up time ranged from 2 to 88 months. Twelve patients with intracranial and skull base invasion needed a combined neurosurgical approach. Eight patients had additional postoperative radiation therapy. RESULTS: The actuarial 3-year survival and local control rate was 60% and 72.8%, respectively. Ten (83.3%) of 12 patients with intracranial and skull base invasion achieved local control. There was no surgical mortality, and the morbidity rate was only 13.2%. CONCLUSION AND SIGNIFICANCE: The results of this study reveal better outcome of salvage surgery than that of most published literature of reirradiation for recurrent NPC. With the adequate exposure provided by the facial translocation approach, an integrated concept of skull base surgery, and the collaboration of neurosurgeons, we can extend our surgical indications of salvage surgery and resect many advanced lesions with acceptable mortality and morbidity.     

Plastic surgery training missions in developing countries. A 10-year experience at missions in Mali

Humanitarian plastic surgery missions are often a substitute, as plastic surgery training missions are essential for the development of plastic surgery in developing countries. This training must be progressive and adapted to the country's needs. Several simple plastic surgery techniques are sufficient to treat a large number of patients: split-skin grafts, full-thickness skin grafts, Z-plasties, latissimus dorsi myocutaneous pedicle flap.     

Pregnancy in patients with prosthetic cardiac valve. A 10-year experience

Pregnancy after valve replacement has been considered hazardous because of maternal and fetal complications secondary to anticoagulant medication, in addition to basic myocardial problems. Of 229 females aged 15-45 years with prosthetic valve replacement, 37 (including 34 with Bj?rk-Shiley valve and anticoagulants) subsequently had a total of 47 pregnancies. Fullterm delivery of a normal infant was achieved in 40 cases. There were three premature births, two spontaneous abortions, one stillbirth and one ectopic pregnancy. The fetal mortality was 8.5%. Valve thrombosis developed in two cases, but surgical treatment was successful. Oral anticoagulants (acenocoumarin and dipyridamole) were continued throughout pregnancy. Heparin was substituted before labour began, but discontinued after delivery, when effective oral anticoagulation was resumed. Our experience showed that pregnancy in women with mechanical heart valve prosthesis and continued oral intake of anticoagulants is safe and successful in most cases.

Clinical outcome versus post-mortem finding in thoracic surgery: a 10-year experience

Objectives: The role of post-mortem following thoracic surgery has not been previously studied. Most importantly, the clinical diagnosis of thoracic surgical mortality cannot be certain unless post-mortem analysis has been performed. Methods: Consecutive post-mortem data were collected on 110 patients between 1992 and 2001 (66.3% of all in-hospital thoracic surgical deaths). Clinically attributed causes of death were compared with post-mortem findings. Results: A total of 4302 thoracic operations were performed during the 10-year period, with overall mortality 3.8%. The mean age was 63.6 years (range 21–87) with 73.6% male. In the 110 patients undergoing post-mortem examination, the operations performed were pneumonectomy 24.5%, lobectomy 14.5%, oesophagectomy 12.7%, lung biopsy 8.2%, pleurectomy/bullectomy 6.4%, decortication 4.5%, lung volume reduction 1.8%, other thoracic 13.6%, other oesophageal 9.1%, and other procedures 4.5%. The mean time to death was 12.5 days (range 0–85). The causes of death were respiratory 47.3%, cardiac 16.4%, multiple organ failure 8.2%, sepsis 6.4%, gastrointestinal 4.5%, haemorrhage/technical failure 10%, and others 7.3%. Post-mortem revealed an unsuspected cause of death in 34 (31%) patients, comprising pulmonary 17, cardiac 5, gastrointestinal 3, haemorrhage/technical failure 2, multiple organ failure 2 and other 5. Conclusion: Post-mortem determined unsuspected diagnoses in a high proportion of patients undergoing thoracic surgery. Post-mortem continues to be the ‘gold standard’ method for attributing the cause of death. Accurate outcome data following thoracic surgery are essential for proper audit, and hence for improvements in clinical practice to occur.
