Laparoscopic assisted live donor nephrectomy--a comparison with the open approach.

Live donor renal transplantation provides significant advantages when compared with cadaveric donor renal transplantation in terms of improved patient and graft survival, a lower incidence of delayed function, and a shorter waiting time. Yet despite these advantages, live donors continue to be an under utilized source of kidneys for transplantation. Disincentives to live donation include the length of hospitalization, postoperative pain, cosmetic concerns, and the prolonged convalescence associated with the donor operation. In many instances minimally invasive video-assisted techniques have proven more efficacious than standard open procedures in terms of patient discomfort, length of hospital stay, cost, and length of time until the patient can return to full activity. Laparoscopic live donor nephrectomies are being performed at our institution in an attempt to make live donation more attractive to the potential donor. The purpose of this study was to retrospectively review the results of laparoscopic live donor nephrectomy (LapNx) and to compare them with those obtained using the standard open approach (OpenNx). Ten consecutive LapNx were performed from February 1995 through April 1996. The control group consisted of the 20 consecutive OpenNx performed at the same institution from January 1991 through January 1995 immediately before the initiation of the LapNx program. Live donors were considered candidates for LapNx if they possessed at least one kidney with normal renal anatomy with single renal vessels and a single ureter. LapNx was safely performed in all cases. No patients required open conversion or blood transfusions. The allograft warm ischemic time for the laparoscopic cases was 4.2+/-1.3 min. All kidneys harvested laparoscopically produced urine on the table immediately upon revascularization. Presently nine of the ten recipients have functioning allografts. At three months posttransplant the calculated recipient creatinine clearances were 67.0+/-11.5 ml/min and 64.8+/-21.4 ml/min for the LapNx and OpenNx groups, respectively (P=NS). The LapNx donors had a significantly decreased estimated blood loss, shorter time until resumption of oral intake, decreased postoperative pain (in terms of decreased analgesic requirements), shorter hospitalization, and a shorter interval until the resumption of full activities (P<0.05 for all). In addition, the LapNx group donors returned to work sooner than the OpenNx group (3.9+/-1.6 wk vs. 6.4+/-3.1 wk, respectively) (P=0.024). Four individuals agreed to donate a kidney only after learning of the availability of the laparoscopic approach. We conclude that laparoscopic live donor nephrectomy is technically feasible. In addition, it may offer significant advantages over the standard open approach in terms of patient comfort and convenience. These advantages may make live donor renal transplantation more attractive to prospective donors. The potential decrease in hospitalization and convalescence may also prove to be financially advantageous. We believe that further careful study of this procedure is warranted.

Kinetics of peripheral blood leukocyte alterations in Thai children with dengue hemorrhagic fever.

Peripheral leukocytes from 16 Thai children with dengue hemorrhagic fever were examined to determine the leukocyte composition on the day of presentation and on convalescent days 15 and 30. Mononuclear cells were isolated each time, and the concentrations of T, B, Fc receptor-bearing, and "null" cells were determined. On the day of hospitalization, in comparison to convalescent values, there was a significant increase in total lymphocytes, primarily due to concentrations of atypical lymphocytes. There was a significant loss of T cells with an increase in non-T, non-B, non-Fc receptor-bearing null cells. There were no changes in the concentrations of monocytes, B cells, or Fc receptor-bearing cells when acute and convalescent values were compared. During the convalescent period, a progressive increase in eosinophils was noted. Also, on day 15 but not on day 30 of the convalescent period, an increase was observed in the total leukocyte number due to an increase in granulocytes. There results indicate that in Thai children with dengue hemorrhagic fever, there are major shifts within several component cell subpopulations of the immune system.

[Fast-track colorectal cancer surgery].

Multimodal rehabilitation with preoperative information, reduction of surgical stress responses, optimised dynamic pain relief and early mobilisation and oral nutrition reduce hospital stay, morbidity and convalescence in colorectal procedures. In addition, the results of fast-track colonic surgery suggest that postoperative pulmonary, cardiovascular and muscle function are improved and body composition preserved. Consequently, the hospital stay may be reduced to about two to four days. Preliminary studies suggest similar improvements in more complex colorectal procedures.

Ureteral reimplantation for management of ureteral strictures: a retrospective comparison of laparoscopic and open techniques.

OBJECTIVES: To compare the results of laparoscopic ureteral reimplantation with a previous series of open surgery. MATERIALS AND METHODS: We compared ten patients who underwent laparoscopic vesicopsoas-hitch with (n=4) or without Boari-flap (n=6) technique for ureteral obstructions with ten patients treated by open ureteroneocystostomy for similar pathologies. Patient demographics, preoperative symptoms, radiologic imaging, and postoperative outcomes were analyzed. Postoperative observation time averaged 17 mo (range: 9-23) in the laparoscopic and 65 mo (range: 18-108) in the open group. Success was defined as relief of obstruction in postoperative imaging studies and relief of pain. RESULTS: Mean length of stricture (28.5 vs. 25 mm) was comparable in both groups. In laparoscopy versus open surgery, mean operative time (228 vs. 187 min) was longer, blood loss (370 vs. 610 ml) and analgesic requirement (4.9 vs. 21.5mg) were significantly lower, and mean time to oral intake (1.5 vs. 2.9 d), hospital stay (9.2 vs. 19.1 d), and convalescence time (2.3 vs. 4.2 wk) were significantly shorter. Success rates yielded 10 of 10 after laparoscopy and 8 of 10 after open surgery. No intra- or postoperative major complications occurred in the laparoscopic series. After open surgery, two patients had major postoperative complications, including urinary extravasation with abdominal haematoma and anastomostic stricture, respectively. CONCLUSIONS: Laparoscopic ureteroneocystostomy is feasible, providing functional outcomes comparable to open surgery while offering the advantages of a minimal invasive technique (e.g., less postoperative analgesics, and shorter hospitalization and convalescence). Nevertheless, it requires a high level of laparoscopic expertise and should be carried out only in specialist centers.

Laparoscopic versus open gastric bypass: a randomized study of outcomes, quality of life, and costs.

OBJECTIVE: To compare outcomes, quality of life (QOL), and costs of laparoscopic and open gastric bypass (GBP). SUMMARY BACKGROUND DATA: Laparoscopic GBP has been reported to be a safe and effective approach for the treatment of morbid obesity. The authors performed a prospective randomized trial to compare outcomes, QOL, and costs of laparoscopic GBP with those of open GBP. METHODS: From May 1999 to March 2001, 155 patients with a body mass index (BMI) of 40 to 60 kg/m2 were randomly assigned to undergo laparoscopic (n = 79) or open (n = 76) GBP. The two groups were similar in age, sex ratio, mean BMI, and comorbidities. Main outcome measures included operative time, estimated blood loss, length of hospital stay, operative complications, percentage of excess body weight loss, and time to return to activities of daily living and work. Changes in QOL were assessed using the SF-36 Health Survey and the bariatric analysis of reporting outcome system (BAROS). Operative and hospital costs of the two operations were also compared. RESULTS: There were no deaths in either group. Mean operative time was longer for laparoscopic GBP than for open GBP, but operative blood loss was less. Two (2.5%) of the 79 patients in the laparoscopic group required conversion to laparotomy. Median length of hospital stay was shorter for laparoscopic GBP patients (3 vs 4 days). The rate of postoperative anastomotic leak was similar between groups. Wound-related complications such as infection (10.5 vs 1.3%) and incisional hernia (7.9 vs 0%) were more common after open GBP; late anastomotic stricture was less frequent after open GBP (2.6 vs 11.4%). Time to return to activities of daily living and work were shorter after laparoscopic GBP than after open GBP. Weight loss at 1 year was similar between groups. Preoperative SF-36 scores were similar between groups; however, at 1 month after surgery, laparoscopic patients had better physical conditioning, social functioning, general health, and less body pain than open GBP patients. At 6 months, the BAROS outcome was classified as good or better in 97% of laparoscopic GBP patients compared with 82% of open GBP patients. Operative costs were higher for laparoscopic GBP patients, but hospital costs were lower. CONCLUSIONS: Laparoscopic GBP is a safe and cost-effective alternative to open GBP. Despite a longer operative time, patients undergoing laparoscopic GBP benefited from less blood loss, a shorter hospital stay, and faster convalescence. Laparoscopic GBP patients had comparable weight loss at 1 year but a more rapid improvement in QOL than open GBP patients. The higher initial operative costs for laparoscopic GBP were adequately offset by the lower hospital costs.

Laparoscopic adrenalectomy: a single-center experience of 43 cases.

PURPOSE: To evaluate the surgical feasibility of laparoscopic adrenalectomy and what laparoscopy offers for the surgeon and the patient. PATIENTS AND METHODS: From March 1996 to June 2004, 43 transperitoneal laparoscopic adrenalectomies were performed for various pathological states. Functioning adrenal masses and solid masses>5 cm were the most common indications. The mean size of the masses on abdominal CT was 6.8 cm in the largest diameter. All patients were assessed regarding the operative time, blood loss, complications, and conversion to open surgery. The postoperative course was reported with special attention to the complications and hospital stay. RESULTS: The mean operative time was 125 minutes with a mean blood loss of 60 mL. Intraoperative complications occurred in 3 cases (6.9%), necessitating conversion to open surgery in 2 to control bleeding from the avulsed right adrenal vein. A third case of conversion was elective because of difficult dissection of a large left pheochromocytoma from the renal hilum, so there was a 6.9% rate of conversion to open surgery. All patients showed early ambulation, early start of eating, and a short hospital stay (mean 2.6 days). CONCLUSION: Laparoscopic adrenalectomy is surgically feasible and can be applied for different adrenal pathologies. The procedure can be performed with a reasonable operative time, minimal blood loss, and an acceptable rate of complications. Laparoscopic adrenalectomy provides excellent postoperative recovery and convalescence with a short hospital stay.

Tubeless percutaneous nephrolithotomy. A comparative study with standard percutaneous nephrolithotomy.

INTRODUCTION: To assess the efficacy, safety and morbidity of tubeless percutaneous nephrolithotomy. MATERIALS AND METHODS: One hundred and fifty-two patients with renal and upper ureteric calculi were included in this study. Sixty-nine patients (71 renal units; group 1) in whom no nephrostomy tube was placed at the conclusion of the procedure was compared with a similar control group of 83 patients (group 2) in whom a nephrostomy tube was placed. Operating time, blood loss, analgesia requirement, puncture site urinary leakage, hospital stay and mean convalescence period were compared in both groups. RESULTS: Both groups were similar with respect to age, sex distribution and stone size. Operating time and blood loss were less in group 1 although they did not reach statistical significance. The mean analgesic requirement, puncture site urinary leakage and hospital stay were significantly less in group 1. CONCLUSION: Tubeless percutaneous nephrolithotomy is a safe and effective procedure in this selected group of patients.

A survey of leptospirosis in febrile patients mainly from hospitals and clinics in Trinidad.

Acute and convalescent sera were obtained from 202 febrile patients, most of whom were admitted to or attended hospitals or clinics in northern Trinidad during the 12 months from mid-February 1977 to mid-February 1978. Laboratory tests confirmed that 10 of the patients were suffering from current leptospirosis while another 54 had serological evidence of previous leptospiral infections. Antibodies to strains of the Icterohaemorrhagiae serogroup were most commonly found, followed by those to the Hebdomadis and Autumnalis serogroups. Isolates were obtained from the blood of two and the urine of three of the 10 current cases. Four of these strains were identified as belonging to copenhageni serovar of the Icterohaemorrhagiae serogroup and one to serovar brasiliensis of the Bataviae serogroup. Seven of the patients suffering from leptospirosis were males, all rural dwellers, and all except one under 20 years of age. Two of the three female patients were over 60 years old and were urban dwellers. It was not possible to identify the sources of infection with certainty, although dogs may have been responsible for three of the Icterohaemorrhagiae and one of the Canicola infections. Of the 192 patients who were not currently infected, serological evidence of previous infection was obtained in 31 (40%) males and 23 (21%) females and was most common among farmers and rural workers.

Response of C-reactive protein and serum amyloid A to influenza A infection in older adults.

Influenza epidemics are associated with significant morbidity and mortality in the elderly, with a substantial proportion of deaths due to cardiovascular events. Elevations of acute-phase proteins have been associated with an increased risk of atherosclerotic events. Therefore, serum amyloid A (SAA) and C-reactive protein (CRP) were measured during influenza illness and 4 weeks later in 7 young persons, 15 elderly outpatients, and 36 hospitalized adults. Striking elevations were seen in mean acute SAA and CRP levels in all groups, but hospitalized patients had the highest levels (SAA, 503 vs. 310 microg/mL [P=.006]; CRP, 120 vs. 34 microg/mL [P<.001]). The presence of dyspnea, wheezing, and fever was also associated with high CRP levels. Influenza infection is associated with significant elevations of SAA and CRP levels in elderly patients, especially those who require hospitalization. It is possible that direct effects of CRP may exacerbate preexisting atherosclerotic lesions and may help explain cardiovascular events associated with acute influenza.

Comparative study of laparoscopic and open adrenalectomy.

BACKGROUND: Laparoscopic adrenalectomy (LA) had become the preferred operation for management of adrenal neoplasm. We conducted this cohort study to evaluate the outcome of laparoscopic and open adrenalectomy (OA). METHODS: A total of 67 patients with complete medical records were included in this study. Thirty patients underwent OA and the other 37 patients received LA. The intraoperative and perioperative data analyses focused on surgery time, blood loss, pain scale rating, resumption of oral feeding, hospital stay, complications and convalescence. RESULTS: LA was completed in all 37 patients without conversion to OA or mortality. The surgery times (203.4 vs. 192.9, p = 0.776) were similar for both OA and LA groups. There was less blood loss in the LA group (355.0 vs. 104.0, p = 0.021). The postoperative pain scale rating was lower in the LA group (5.6 vs. 4.5 p = 0.035) as was analgesia demand (57.4 vs. 3.7, p < 0.001). Oral feeding resumed earlier in the LA group (91.7 vs. 16.4, p < 0.001) and these patients had a shorter postoperative hospital stay (8.4 vs. 3.9, p < 0.001). The complication rate in both groups was similar. In the LA group, patients with primary aldosteronism had shorter surgery times and less blood loss than patients with other tumor types (p < 0.05). CONCLUSIONS: LA results in good surgical outcome without increased risks. We suggest that LA should be the preferred choice for management of adrenal neoplasms. We also suggest that surgeons inexperienced in LA consider beginning with a case of primary hyperaldosteronism.

Experience of using convalescent plasma for severe acute respiratory syndrome among healthcare workers in a Taiwan hospital.

OBJECTIVES: To describe the immunological responses and clinical outcome of coronavirus (SARS) infected healthcare workers (HCW) who had been administered with convalescent plasma as a treatment. METHODS: Convalescent plasma (500 mL) was obtained from each of three SARS patients and transfused into the three infected HCW. Donors were blood type O and seronegative for hepatitis B and C, HIV, syphilis and human T-cell lymphotropic virus types I and II (HTLV-I and -II). Serum antibody (IgG) titre was >640. Apharesis was performed with a CS 3000 plus cell separator followed by the forming of the convalescent phase plasma. As part of the routine check with donated plasma, the convalescent plasma was confirmed free of residual SARS-CoV by RT-PCR. Serial serum samples obtained from the recipients of the convalescent plasma were collected to undertake real-time quantitative RT-PCR for SARS-CoV for direct measurement of viral concentration. Specific immunoglobulin IgM and IgG concentrations were titrated using an antigen microarray developed in-house. RESULTS: Viral load dropped from 495 x 10(3), 76 x 10(3) or 650 x 10(3) copies/mL to zero or 1 copy/mL one day after transfusion. Anti-SARS-CoV IgM and IgG also increased in a time-dependent manner following transfusion. All three patients survived. One HCW became pregnant subsequently, delivering 13 months after discharge. Positive anti-SARS-CoV IgG was detected in the newborn. Passive transfer of anti-SARS-CoV antibody from the mother was considered as a possibility. CONCLUSIONS: All infected HCW whose condition had progressed severely and who had failed to respond to the available treatment, survived after transfusion with convalescent plasma.

[Descriptive analysis of patients admitted to hospital for acute cerebrovascular disease].

INTRODUCTION: Acute cerebrovascular disease (ACVA) makes up a high proportion of the neurological patients admitted to hospital, but we do not know the exact figures in our setting. We consider that it would be useful if the use of health-care resources for attending these patients was to be evaluated and studied by the neurologists who direct them. OBJECTIVE: To analyze a predetermined series of variables related to strokes in our setting. Patients and methods. We made a descriptive analysis by means of a questionnaire, recording variables related to the admission to the neurology department of patients with probable ACVA, at 100 days and with further evaluation 6 months later. RESULTS: We recorded 107 cases with ACVA confirmed in 101 of 104 patients with averages of: 70.54 years, average admission 13.53 days and intrahospital mortality 5.8%. The most common neurological findings were paralysis and speech disorder. The proportion of ischaemic stroke as compared with haemorrhagic stroke was 87.5% to 12.5%. The prevalence of usual risk factors was: arterial hypertension, diabetes and cardiopathy. The percentage of patients given rehabilitation treatment during their admission was 41.34%. A proportion, 37.2%, of the patients were referred to Hospital San Rafael for convalescence and treatment. The average time before evaluation by a neurologist was 30.23 hours. Eleven of 86 patients who answered a weekly questionnaire died (12.8%) and 54/86 had no rehabilitation treatment during the week (62.8%). CONCLUSIONS: We found no differences in the epidemiological characteristics as compared with other studies. The excessive lapse of time before attending the emergency department was striking, as was the delay in receiving neurological attention since there was no emergency neurologist available and fewer haemorrhagic strokes since there was no neurosurgical service available. There was little use of salicylates as a platelet anti-aggregrant agent on discharge from hospital, little rehabilitation treatment six months after the stroke, and twice as much mortality as when the patients were in hospital. We consider that a more detailed and extensive analysis would be fully justified in our setting, preferably with more people interested in the early and late treatment of ACVA taking part and prolonged follow-up of these patients.
