Comparison of ultrasonic energy, bipolar thermal energy, and vascular clips for the hemostasis of small-, medium-, and large-sized arteries.
BACKGROUND: Advanced laparoscopic procedures have necessitated the development of new technology for vascular control. Suture ligation can be time-consuming and cumbersome during laparoscopic dissection. Titanium clips have been used for hemostasis, and recently plastic clips and energy sources such as ultrasonic coagulating shears and bipolar thermal energy devices have become popular. The purpose of this study was to compare the bursting pressure of arteries sealed with ultrasonic coagulating shears (UCS), electrothermal bipolar vessel sealer (EBVS), titanium laparoscopic clips (LCs), and plastic laparoscopic clips (PCs). In addition, the spread of thermal injury from the UCS and the EBVS was compared. METHODS: Arteries in three size groups (2-3, 4-5 and 6-7 mm) were harvested from freshly euthanized pigs. Each of the four devices was used to seal 16 specimens from each size group for burst testing. A 5-Fr catheter was placed into the open end of the specimen and secured with a purse-string suture. The catheter was connected to a pressure monitor and saline was infused until there was leakage from the sealed end. This defined the bursting pressure in mmHg. The ultrasonic shears and bipolar thermal device were used to seal an additional 8 vessels in each size group, which were sent for histologic examination. These were examined with hematoxylin and eosin stains, and the extent of thermal injury, defined by coagulation necrosis, was measured in millimeters. Analysis of variance was performed and, where appropriate, a Tukey's test was also performed. RESULTS: The EBVS's mean burst pressure was statistically higher than that of the UCS at 4 or 5 mm (601 vs 205 mmHg) and 6 or 7 mm (442 vs 175 mmHg). EBVS had higher burst pressures for the 4 or 5-mm group (601 mmHg) and 6 or 7-mm group (442 mmHg) compared with its pressure at 2 or 3 mm (128 mmHg) ( p = 0.0001). The burst pressures of the UCS and EBVS at 2 or 3 mm were not significantly different. Both clips were statistically stronger than the thermal devices except at 4 or 5 mm, in which case the EBVS was as strong as the LC (601 vs 593 mmHg). The PC and LC were similar except at 4 or 5 mm, where the PC was superior (854 vs 593 mmHg). The PC burst pressure for 4 or 5 mm (854 mmHg) was statistically higher than that for vessels 2 or 3 mm (737 mmHg) but not different from the 6 or 7 mm pressure (767 mmHg). Thermal spread was not statistically different when comparing EBVS and UCS at any size (EBVS mean = 2.57 mm vs UCS mean = 2.18 mm). CONCLUSIONS: Both the PC and LC secured all vessel sizes to well above physiologic levels. The EBVS can be used confidently in vessels up to 7 mm. There is no difference in the thermal spread of the LigaSure vessel sealer and the UCS.

Laparoscopic repair of traumatic diaphragmatic injuries.
BACKGROUND: The purpose of this study was to evaluate the feasibility and limitations of laparoscopic repair of traumatic diaphragmatic injuries. METHODS: Laparoscopic repair of an acute traumatic diaphragmatic laceration or chronic traumatic diaphragmatic hernia was attempted in 17 patients between January 1997 and January 2001. The patients in the study included 13 men and 4 women with a mean age of 33.2 years (range, 15-63 years). Nine patients had a blunt injury, and eight patients had a penetrating injury. Laparoscopic repair was attempted for eight patients during their hospitalization for the traumatic injury (mean, 2.3 days; range, 0-6 days) and for ten patients with a chronic diaphragmatic hernia (mean, 89 months; range, 5-420 months). The chronic diaphragmatic hernias-presented with abdominal pain (9/9), or vomiting (3/9). RESULTS: Thirteen traumatic diaphragmatic injuries were repaired laparoscopically, and four (2 acute and 2 chronic) required conversion. Among the laparoscopically repaired diaphragmatic injuries, three defects (chronic) were repaired using expanded polytetrafluoroethylene (ePTFE), and nine were repaired primarily. The mean length of the diaphragmatic defects was 4.6 cm (range, 1.5-12 cm). The mean operative time was 134.7 min (range, 55-200 min). The mean estimated blood loss was 108.5 ml (range, 30-500 ml), and the postoperative length of stay was 4.4 days (range, 1-12 days). There were no intraoperative complications, but three patients developed pulmonary complications (atelectasis/pneumonia). Follow-up evaluation was available for 11 patients. There were no documented recurrences after a mean follow-up period of 7.9 months (range, 1 week to 24 months). Conversion resulted from a reluctance or inability to perform laparoscopic suture of transverse diaphragmatic lacerations longer than 10 cm anterior to the esophageal hiatus and adjacent to the pericardium (n = 2) or communicating with the esophageal hiatus (n = 2). One patient also required spleneotomy for an unrecognized splenic laceration that had occurred at the time of the original trauma. The four patients undergoing laparotomy had a mean postoperative discharge date of 8.7 days (range, 6-14 days). CONCLUSIONS: Laparoscopy is an alternative approach to repairing acute traumatic diaphragmatic lacerations and chronic traumatic diaphragmatic hernias. Large traumatic diaphragmatic injuries adjacent to or including the esophageal hiatus are best approached via laparotomy.

Laparoscopic vs open resection of gastric stromal tumors.
BACKGROUND: Gastric stromal tumors are rare neoplasms that may be benign or malignant. Given that malignant gastric stromal tumors rarely involve lymph nodes and require excision with negative margins, they appear amendable to laparoscopic excision. There are few reports of laparoscopic resection, and no comparisons have been done between laparoscopic and open surgery. This study compares the relative efficacy of the two approaches. METHODS: Between May 1994 and December 2000, 33 patients underwent 35 operations for gastric stromal tumors. Laparoscopic resections were performed in 21 patients; open resections were done in 12 patients. The medical records of the patients were reviewed retrospectively with regard to operating time, blood loss, length of stay, and clinical course. RESULTS: Patient demographics, tumor characteristics (mean tumor size, benign vs malignant), and presenting symptoms were similar for both groups. In the laparoscopic group, 15 wedge resections; three partial gastrectomies, and three transgastric needlescopic enucleations were performed. In the open group, six wedge resections, four antrectomies, and two partial proximal gastrectomies were performed. There were no significant differences in mean operative time (169 vs 160 min), mean estimated blood loss (106 vs 129 cc), or perioperative complication rate (9.5% vs 8.3%) between the laparoscopic and open groups, respectively. The mean length of stay was significantly less (p<0.05) in the laparoscopic group (3.8 vs 6.2 days). Average follow-up was 1.5 years. One patient in each group has died due to metastatic disease. There have been no trocar site recurrences. CONCLUSIONS: Laparoscopic resection of gastric stromal tumors is safe and appropriate. Tumor size, operating time, and estimated blood loss were equivalent to the open approach, and there was a statistically shorter hospital stay in the laparoscopic group.

Optimal teaching environment for laparoscopic ventral herniorrhaphy.
The introduction of laparoscopic techniques after residency training has created a new paradigm dependent on laparoscopic workshops. This study tested the benefit of an animate course and evaluated the role of proctoring in learning to perform laparoscopic ventral hernia repair (LVHR). Surgeons who had taken a 1-day LVHR course (n = 59) were polled to determine previous experience with laparoscopic procedures and experience with LVHR after the course. Forty-eight (81%) surgeons completing the course responded. Thirty-two (67%) surgeons had performed 179 LVHRS (mean 5.6) since the course. There were no statistically significant differences between the groups performing and not performing LVHR regarding academic/private practice (P=0.8) or opportunities to perform a ventral herniorrhaphy (P = 0.6). Fifteen (31%) surgeons were precepted in their hospital operating room by the lead author. Thirteen (87%) of precepted surgeons had performed a LVHR compared with 19 (58%) of the 33 surgeons taking the course without a precepted intervention (P = 0.05). Surgeons with experience performing laparoscopic inguinal hernia repair, Nissen fundoplication, and common bile duct exploration were more likely to perform LVHR (P=0.0001). Surgeons performing only laparoscopic cholecystectomy tended to be less likely to perform LVHR, nearing statistical significance (P=0.08). Surgeons with prior advanced laparoscopic surgery experience are thus more likely to perform LVHR after participating in a 1-day course. Surgeons precepted in their hospital operating room were also more likely to perform LVHR. Participation in an animate laboratory and a precepted experience can impact the future performance of advanced laparoscopic surgery.

Outcomes for laparoscopic bilateral adrenalectomy.
BACKGROUND AND PURPOSE: Laparoscopic adrenalectomy has become the preferred surgical approach to manage adrenal disorders. Bilateral adrenalectomy is performed for diseases that are unresponsive to medical management and, frequently, for neoplastic disease. The aim of this study was to review our experience with laparoscopic bilateral adrenalectomy and to evaluate its safety, efficacy, and outcomes. PATIENTS AND METHODS: Between July 1996 and May 2001, five male and two female patients with a mean age of 46 years (range 15-69 years) presented for bilateral adrenalectomy (pheochromocytoma [N = 3], Cushing's disease [N = 3], and metastatic cancer [N = 1]). All procedures were performed using a lateral transperitoneal approach. One gland was excised, the patient was repositioned to the opposite lateral decubitus position, and the remaining gland was removed. RESULTS: Laparoscopic bilateral adrenalectomy was completed in all seven patients. The mean tumor/gland size on the right was 5.0 cm (range 3.1-7.0 cm) and on the left was 5.6 cm (range 3.6-7.0 cm). The mean operative time was 308 minutes (range 190-430 minutes), and the mean estimated blood loss was 138 mL (range 30-300 mL). One patient with a pheochromocytoma experienced intraoperative hypertension necessitating treatment. There were no postoperative complications. The mean postoperative hospital stay was 5.1 days (range 3-9 days). All patients have been treated postoperatively with daily hydrocortisone and fludrocortisone replacement. After a mean follow-up of 33 months (range 2-45 months), six patients are alive. The patient undergoing bilateral adrenalectomy for metastatic lung cancer died from recurrent disease 13 months after resection. CONCLUSION: Laparoscopic bilateral adrenalectomy is safe and effective. Patients are discharged postoperatively in a relatively short time with few complications. Appropriate steroid replacement and close follow-up allows these patients to return to self-reliance.

Laparoscopic adrenalectomy for pheochromocytoma.
BACKGROUND: Laparoscopic adrenalectomy for Conn's syndrome, Cushing's disease, cortisol-producing adenomas, and nonfunctioning adenomas has been well established. This study was intended to evaluate the clinical outcomes of patients undergoing laparoscopic adrenalectomy for pheochromocytoma, and to assess the efficacy and safety of a minimally invasive approach. METHODS: Data were collected prospectively on all patients undergoing laparoscopic adrenalectomy for pheochromocytoma over a 5-year period. RESULTS: In this study, 39 consecutive patients underwent laparoscopic resection of a pheochromocytoma: 38 adrenal (23 left, 15 right) and 1 extraadrenal paraganglioma. There were no conversions to open surgery. The mean tumor size was 5.2 cm (range, 2-12.1 cm). Average operative time was 159 min (range, 100-265 min), and average estimated blood loss was 72 ml (range, 30-350 ml). Intraoperative hypertension (systolic blood pressure > 170 mmHg) occurred in 67% of the patients, and hypotension (systolic blood pressure < 90 mmHg) in 39% of the patients. The mean length of stay was 2.1 days (range, 1-4 days). There were three minor postoperative complications. During a mean follow-up period of 14 months, there were no mortalities or recurrences of endocrinopathy. CONCLUSIONS: Laparoscopic resection of pheochromocytomas can be accomplished safely despite frequent episodes of hemodynamic variability equal to those of historic open control subjects. A short hospital stay with expedient recovery,minimal wound complications, and lack of endocrinopathy recurrence makes a minimally invasive approach the procedure of choice for the management of pheochromoctyoma.

Mini-laparoscopic versus laparoscopic approach to appendectomy.
BACKGROUND: The purpose of this clinical study is to evaluate the feasibility of using 2-mm laparoscopic instruments to perform an appendectomy in patients with clinically suspected acute appendicitis and compare the outcome of this mini-laparoscopic or "needlescopic" approach to the conventional laparoscopic appendectomy. METHODS: Two groups of patients undergoing appendectomy over 24 months were studied. In the first group, needlescopic appendectomy was performed in 15 patients by surgeons specializing in advanced laparoscopy. These patients were compared with the second or control group that included 21 consecutive patients who underwent laparoscopic appendectomy. We compared the patients' demographic data, operative findings, complications, postoperative pain medicine requirements, length of hospital stay, and recovery variables. Differences were considered statistically significant at a p-value < 0.05. RESULTS: Patient demographics, history of previous abdominal surgery, and operative findings were similar in both groups. There was no conversion to open appendectomy in either group. No postoperative morbidity or mortality occurred in either group. The needlescopic group had a significantly shorter mean operative time (p = 0.02), reduced postoperative narcotics requirements (p = 0.05), shorter hospital stay (p = 0.04), and quicker return to work (p = 0.03) when compared with the laparoscopic group. CONCLUSIONS: We conclude that the needlescopic technique is a safe and effective approach to appendectomy. When performed by experienced laparoscopic surgeons, the needlescopic technique results in significantly shorter postoperative convalescence and a prompt recovery.

Minimally invasive management of paraesophageal herniation in the high-risk surgical patient.
BACKGROUND: Traditional management of symptomatic paraesophageal herniation involves hernia reduction, hiatal closure, and an antireflux procedure or gastropexy. Patients with significant comorbidities may not tolerate operative repair. A new technique, laparoscopic-assisted endoscopic reduction and fixation of the stomach, may provide a minimally invasive treatment alternative. METHODS: Eleven elderly patients with symptomatic paraesophageal herniation were managed with flexible endoscopy and double percutaneous endoscopic gastrostomy (PEG) tube insertion with or without laparoscopic assistance. RESULTS: All patients presented with a symptomatic paraesophageal hernia. Mean age was 78.3 years (range 72 to 84). Each was deemed at high risk for definitive repair due to preexisting coronary artery disease as well as at least two other serious comorbidities. Hernia reduction and intra-abdominal fixation of the stomach was achieved in each case using flexible endoscopy and double PEG insertion. Laparoscopic assistance for reduction and gastropexy was utilized in 9 cases. Mean operative time was 61 minutes (range 28 to 104). Average length of stay was 2.8 days (range 0 to 12). One minor and three major postoperative complications occurred. Over a mean follow-up of 4.1 months (range 2 to 7), all patients have resumed oral intake and achieved weight gain. CONCLUSIONS: Patients with symptomatic paraesophageal herniation require intervention to alleviate symptoms and avoid the complications of gastric incarceration. For the high-risk patient, endoscopic reduction and PEG with laparoscopic assistance appears to provide effective treatment.

Lateral approach to laparoscopic cholecystectomy in the previously operated abdomen.
BACKGROUND: In the past, prior abdominal surgery was often felt to be a contraindication to laparoscopic cholecystectomy. The presence of adhesions precludes using a simple paraumbilical open approach for insufflation and initial trocar insertion because of an increased risk of bowel perforation and the difficulty in obtaining adequate exposure. PATIENTS AND METHODS: We report 32 consecutive patients with previous upper midline incisions who underwent laparoscopic cholecystectomy with cholangiography and describe the technique and lateral positioning to facilitate this approach. RESULTS: In our series, there were no complications. The mean length of hospital stay was 1.3 days, and the conversion rate to an open procedure was 3%: one patient who had had 22 previous abdominal operations. CONCLUSION: Laparoscopic cholecystectomy performed with the patient in the lateral position is safe and effective for patients who have had previous midline incisions.

Minilaparoscopic appendectomy.
The purpose of this study was to evaluate the feasibility of using 2-mm laparoscopic instruments in the treatment of appendicitis and to identify risk factors that may limit their use. Minilaparoscopic appendectomy was performed through a 2-mm port in the umbilicus for a videoendoscope, a 2-mm working port in the right upper quadrant, and a 5/12-mm suprapubic port for an endoscopic stapler. Minilaparoscopic appendectomy was attempted in 26 consecutive patients with appendicitis. Thirty-two consecutive patients undergoing conventional laparoscopic appendectomy with 5- and 10-mm instruments and videoendoscopes before the availability of 2-mm instrumentation were analyzed for comparison. Statistical comparisons were made by the Student t test and Fisher exact test. Differences were considered statistically significant at a P value less than 0.05. There were no conversions to an open appendectomy in the minilaparoscopic appendectomy or conventional laparoscopic appendectomy group. The mean operative time was 69.5 minutes for the minilaparoscopic appendectomy group and 85.5 minutes for the conventional laparoscopic appendectomy group (P = 0.02). The mean postoperative length of stay was 1.7 days for the minilaparoscopic appendectomy group and 2.5 days for the conventional laparoscopic appendectomy group (P = 0.08). There was no significant difference in the complication rates (P = 0.31). Minilaparoscopic appendectomy was completed in 13 (50.0%) patients. Independent risk factors (P = 0.05) for conversion to 5- or 10-mm ports were a retrocecal appendix and increasing patient age. There were no differences in the mean postoperative length of stay (P = 0.12) or complication rate (P = 0.39) between the two groups, but mean operative time was longer (P = 0.05) in the converted group. Perioperative outcomes for minilaparoscopic appendectomy are comparable to those of conventional laparoscopic appendectomy. The use of 2-mm instrumentation in the management of appendicitis is limited in patients with retrocecal appendicitis. Increasing patient age and a history of abdominal surgery may influence the need to convert 2-mm ports to 5- or 10-mm ports.

Laparoscopic splenectomy in patients with normal-sized spleens versus splenomegaly: does size matter?
Laparoscopic resection has become the standard means for removal of normal-sized spleens in many medical centers. The application of minimally invasive techniques in the setting of splenomegaly is less well defined and was previously considered a contraindication to the laparoscopic approach. The purpose of this prospective study of consecutive patients was to compare the outcomes of patients undergoing laparoscopic splenectomy for normal-sized spleens (150 g or less) versus those with clear evidence of splenomegaly (500 g or greater). One hundred forty-two patients met the inclusion criteria. The most common diagnosis in the normal-sized spleen group was idiopathic thrombocytopenia purpura (67 of 82, 82%). Malignant hematologic diseases (lymphoma and leukemia) were the most common diagnoses in the splenomegaly group (35 of 60, 58%). Mean operative times (127 vs 172 minutes) and estimated blood loss (123 vs 173 cm3) were lower for those patients with normal-sized spleens (P < 0.05). There were no statistical differences in conversion rates, lengths of stay, or complications between the two groups. We conclude that laparoscopic splenectomy is safe and effective in the setting of splenomegaly despite modest but statistically longer operative times and increased operative blood loss when compared with laparoscopic splenectomy for normal-sized spleens.

Effectiveness of the ultrasonic coagulating shears, LigaSure vessel sealer, and surgical clip application in biliary surgery: a comparative analysis.
Advancements in laparoscopic surgery are often dictated by the limitations of technical instrumentation. Energy sources other than electrosurgery have become popular with the promise of quick and effective vascular control. With their success surgeons have begun using these on structures other than blood vessels with little or no data establishing their efficacy or safety. This study evaluates alternative energy sources in sealing ductal structures for possible use in liver or gallbladder surgery. After elective cholecystectomy cystic ducts (n = 45) were resealed ex vivo with surgical clips (n = 14), ultrasonic coagulating shears (n = 16), or electrothermal bipolar vessel sealer (n = 15), and bursting pressures were measured. Nineteen additional human cystic ducts were randomized to seal by ultrasonic coagulating shears (n = 9) or electrothermal bipolar vessel sealer (n = 10) and fixed in 10 per cent buffered formalin for histologic evaluation of thermal spread (mm). After this nine adult pigs were randomized to laparoscopic ligation and transection of the common bile duct using surgical clips (n = 3), ultrasonic coagulating shears (n = 3), or electrothermal bipolar vessel sealer (n = 3). The animals underwent necropsy for assessment of seal integrity on the sixth postoperative day. In the ex vivo study the mean cystic duct bursting pressure was 621 mm Hg with surgical clips and 482 mm Hg with the electrothermal bipolar vessel sealer (P = 0.39). The mean cystic duct bursting pressure after ultrasonic coagulating shears was 278 mm Hg, which was statistically less than surgical clips (P = 0.007) and electrothermal bipolar vessel sealer (P = 0.02). The mean thermal spread was 3.5 mm for ultrasonic coagulating shears and 13.4 mm for electrothermal bipolar vessel sealer (P = 0.0002). All animals undergoing ligation and transection of the common bile duct with ultrasonic coagulating shears and electrothermal bipolar vessel sealer developed bile peritonitis by postoperative day 6 as a result of seal leak. All animals undergoing surgical clip ligation and transection of the common bile duct maintained seal integrity. The mean common bile duct pressure above the surgical clip was 12 mm Hg (range 10-14). In conclusion the acute ex vivo study demonstrated a significant difference in the cystic duct bursting pressure between surgical clips and ultrasonic coagulating shears and between electrothermal bipolar vessel sealer and ultrasonic coagulating shears. The ultrasonic coagulating shears and electrothermal bipolar vessel sealer failed to maintain seal integrity in the in vivo animal study. Given the failure of the ultrasonic coagulating shears and electrothermal bipolar vessel sealer in the animal model these energy sources should not be used for transection of the cystic duct or major hepatic ducts during hepatobiliary surgery.

Laparoscopic anterior esophageal myotomy and toupet fundoplication for achalasia.
Achalasia is an esophageal motility disorder characterized by the failure of lower esophageal sphincter relaxation and the absence of esophageal peristalsis. The purpose of this study was to evaluate the clinical outcomes of patients undergoing laparoscopic esophageal myotomy and Toupet fundoplication for achalasia. A 9-cm myotomy was performed in most cases extending 7 cm above and 2 cm below the gastroesophageal junction. Severity of dysphagia, heartburn, chest pain, and regurgitation was graded preoperatively and postoperatively using a five-point symptomatic scale (0-4). Patients also graded their outcomes as excellent, good, fair, or poor. Between December 1995 and November 2000 a total of 49 patients (23 male, 26 female) with a mean age of 44.3 years (range 23-71 years) were diagnosed with achalasia. Mean duration of symptoms was 40.2 months (range 4-240 months). Thirty-seven patients (76%) had had a previous nonsurgical intervention or combinations of nonsurgical interventions [pneumatic dilation (23), bougie dilation (five), and botulinum toxin (19)], and two patients had failed esophageal myotomies. Forty-five patients underwent laparoscopic esophageal myotomy and Toupet fundoplication. Two patients received laparoscopic esophageal myotomies without an antireflux procedure, and two were converted to open surgery. One patient presented 10 hours after a pneumatically induced perforation and underwent a successful laparoscopic esophageal myotomy and partial fundoplication. Mean operative time was 180.5 minutes (range 145-264 minutes). Mean length of stay was 1.98 days (range 1-18 days). There were five (10%) perioperative complications but no esophageal leaks. There was a significant difference (P < 0.05) between the preoperative and postoperative dysphagia, chest pain, and regurgitation symptom scores. All patients stated that they were improved postoperatively. Eighty-six per cent rated their outcome as excellent, 10 per cent as good, and 4 per cent as fair. Laparoscopic anterior esophageal myotomy and Toupet fundoplication effectively alleviates dysphagia, regurgitation, and chest pain accompanying achalasia and is associated with high patient satisfaction, a rapid hospital discharge, and few complications.

Thoracoscopic decortication as first-line therapy for pediatric parapneumonic empyema. A case series.
STUDY OBJECTIVES: Previous articles have promoted the early use of thoracotomy and decortication for refractory empyema. This study examines thoracoscopy and decortication at the time of initial chest tube placement in pediatric patients with parapneumonic empyema. DESIGN: We reviewed the medical records of 16 consecutive patients who were children with parapneumonic empyema. RESULTS: Thirteen children (group 1) underwent thoracoscopic decortication and tube thoracostomy as their initial operative procedures; 3 children (group 2) had tube thoracostomy alone. In both groups, chest tubes were removed prior to their discharge to home. The mean (+/- SD) operative time for thoracoscopy was 81 +/- 19 min with no complications. On average, chest tubes were removed by postoperative day 4. The mean time to discharge was 8.3 days. Two children eventually required lobectomy. The mean operative time for chest tube placement alone was 21 +/- 3 min. Children required chest tube drainage for an average of 12.3 days. The mean time to discharge was 16.6 days. Two patients required a total of five additional operative procedures, including two additional chest tube placements, two open decortications, and one lobectomy. CONCLUSIONS: Thoracoscopic decortication is effective in the early treatment of pediatric parapneumonic empyema. It facilitates visualization, evacuation, and mechanical decortication of the pleural space with no additional morbidity and may lead to reduced time for chest tube drainage, shorter hospitalization, and more rapid clinical recovery.

Laparoscopic intraoperative ultrasonic localization and resection of an extra-adrenal pheochromocytoma.
With advances in minimally invasive techniques, the safety and efficacy of laparoscopic adrenalectomy is well documented. Compared with open surgery, the laparoscopic approach results in shorter hospital stay, reduced morbidity, and more rapid recovery. In the setting of pheochromocytoma, tumor resection is feasible although somewhat more difficult because of catecholamine liberation and frequent large lesion size. We report the successful laparoscopic resection of a para-aortic, extra-adrenal paraganglioma using ultrasound guidance.

Survival, quality of life, and charges in critically III surgical patients requiring prolonged ICU stays.
UNLABELLED: Critical care consumes a significant portion of health care costs. Although there are currently increasing pressures to limit expenditures, data are not always available to allow physicians and patients to make informed therapeutic or triage decisions regarding prolonged intensive care unit (ICU) stays. The purpose of this study was to evaluate long-term outcome, quality of life, and charges in surgical patients requiring prolonged ICU stays (> 14 days). METHODS: Adults requiring over 14 days of surgical ICU care from January 1991 to September 1993 were selected from our ICU data base. Survivors to hospital discharge were evaluated for outcome and quality of life by mail survey and/or telephone interview in addition to chart review. RESULTS: Eighty-three patients spent over 14 days in the surgical ICU during the study period. Fifty-two patients (62.6%) survived to hospital discharge. Average age was 53 years, average ICU length of stay was 26 days, and average hospital length of stay was 50 days. Complete follow-up data were available for 39 patients (75%). Thirty of the 39 patients (77%) were alive at an average follow-up of 18 months. Long-term survival in patients over 65 years old was 67% compared with 83% for younger patients (p < 0.05). Seventy percent reported less than 50% functional recovery. Seventy percent wer living at home and 23% were on disability. Of 11 patients employed before discharge, five had returned to work. Eighty percent of respondents reported good to fair quality of life, and 81% stated that they would undergo critical care again. The average ICU charge was $51,512 per patient, and the average hospital charge was $164,019 per patient. The average charge to achieve one long-term survivor was $247,812. CONCLUSIONS: In this population, prolonged ICU stays resulted in acceptable quality of life and a relatively high survival rate despite significant economic investment. This study does not support withdrawal of therapy or triage decisions based solely or primarily on age or length of ICU stay.
