Laparoscopic nephrectomy: the learning-curve experience.

OBJECTIVE: To report the learning-curve experience with laparoscopic nephrectomy. DESIGN: Case series. SETTING: A tertiary-care referral centre serving southern Saskatchewan. PATIENTS: Sixteen patients (7 men, 9 women), selected to undergo laparoscopic nephrectomy. They ranged in age from 19 to 83 years. Indications for surgery were: recurrent atrophic pyelonephritis with pain (three patients), obstruction at the ureteropelvic junction with pain (three), small ectopic kidney with pain (one), renovascular hypertension (two), a solid renal mass confirmed by computed tomography (four), Staghorn calculus (one), transitional cell tumour of upper ureter (one) and pyonephrosis with a nonfunctioning kidney (one). INTERVENTIONS: Laparoscopic nephrectomy. MAIN OUTCOME MEASURES: Postoperative morbidity, complications of the procedure and duration of postoperative hospitalization. RESULTS: Kidneys were removed laparoscopically in 13 patients. Open nephrectomy was necessary in three patients, owing to a lack of experience in patient selection in two cases and to intraoperative hemorrhage in the third. All patients resumed oral intake on the 1st postoperative day, and most did not require analgesics for relief of pain beyond 36 hours postoperatively. Complications of laparoscopic nephrectomy included pneumonia (one patient), low-grade fever (two patients), need for blood transfusion (three patients) and transient ischemic attack (one patient). The mean postoperative hospital stay was 4.3 days. CONCLUSIONS: When patients are properly selected, laparoscopic nephrectomy provides decreased postoperative morbidity, a shorter convalescence, and thus cost savings, compared with open nephrectomy.

Laparoscopic versus open partial nephrectomy.

OBJECTIVES: To compare, retrospectively, the results of laparoscopic partial nephrectomy (LPN) to open partial nephrectomy (OPN) using a tumor size-matched cohort of patients. Limited data are available comparing LPN to OPN in the treatment of small renal tumors. METHODS: Between September 2000 and September 2003, 27 LPNs and 22 OPNs were performed to treat renal masses less than 4 cm. Patient demographics and tumor location and size (2.4 +/- 1.0 cm versus 2.9 +/- 0.9 cm, respectively; P = not statistically significant) were similar between the LPN and OPN groups. RESULTS: Although the mean operative time was longer in the LPN than in the OPN group (210 +/- 76 minutes versus 144 +/- 24 minutes; P <0.001), the blood loss was comparable between the two groups (250 +/- 250 mL versus 334 +/- 343 mL; P = not statistically significant). No blood transfusions were performed in either group. The hospital stay was significantly reduced after LPN compared with after OPN (2.9 +/- 1.5 days versus 6.4 +/- 1.8 days; P <0.0002), and the postoperative parenteral narcotic requirements were lower in the LPN group (mean morphine equivalent 43 +/- 62 mg versus 187 +/- 71 mg; P <0.02). Three complications occurred in each group. With LPN, no patient had positive margins or tumor recurrence. Also, direct financial analysis demonstrated lower total hospital costs after LPN (4839 dollars+/- 1551 dollars versus 6297 dollars+/- 2972 dollars; P <0.05). CONCLUSIONS: LPN confers several benefits over OPN concerning patient convalescence and costs, despite prolonged resection times at our current phase of the learning curve. Long-term results on cancer control in patients treated with LPN continue to be assessed.

Human opsonins induced during meningococcal disease recognize transferrin binding protein complexes.

Patient serum opsonins against transferrin binding protein A+B (TbpA+B) complexes from two Neisseria meningitidis strains (K454 and B16B6, with 85- and 68-kDa TbpB, respectively) were quantified by a functional phagocytosis and oxidative burst assay. TbpA+B complexes adsorbed to fluorescent beads were opsonized with individual acute and convalescent sera from 40 patients infected by a variety of meningococcal strains. Flow cytometric quantitation of leukocyte phagocytosis products (PP) demonstrated that disease-induced serum opsonins recognized TbpA+B, and the highest anti-TbpA+B serum opsonic activities were found between admission to hospital and 6 weeks later. The PP values obtained with TbpA+B from strain B16B6 (PP(B16B6)) were higher than those obtained with TbpA+B from strain K454 (PP(K454)), with both acute and convalescent sera (P < 0.0001), and correlated positively with higher immunoglobulin G enzyme-linked immunosorbent assay titers against TbpA+B from strain B16B6 than from strain K454 (P < 0.001). In spite of considerable variations between individuals, significant correlations were found between the PP(B16B6) and PP(K454) values, and the PP values did not depend on the variability of the TbpB proteins of the disease-causing strains. Simultaneously measured oxidative burst activity correlated closely with the PP values. We conclude that highly cross-reactive anti-TbpA+B serum opsonins are produced during meningococcal disease. The anti-TbpA+B opsonic activities were not affected by the variability of the TbpB proteins of the disease-causing strains, which further adds to the evidence for the vaccine potential of meningococcal TbpA+B complexes.

Clipless laparoscopic adrenalectomy with needlescopic instruments.

PURPOSE: We describe our experience with clipless laparoscopic adrenalectomy using needlescopic instruments. We compared the results with those of a contemporary series of conventional laparoscopic adrenalectomy. MATERIALS AND METHODS: In 12 patients clipless laparoscopic adrenalectomy was performed with needlescopic instruments in an 8-month period. The technique included 2 or 3 subcostal 2 mm. ports and 1 umbilical 5/12 mm. port for the telescope and ultimate specimen extraction. Adrenal vessels were controlled by bipolar coagulation without endoscopic clips. Outcome data were retrospectively compared with those on 20 recent conventional laparoscopic adrenalectomies done at the same institution. The 2 types of laparoscopic adrenalectomy were performed transperitoneally. RESULTS: Patients in the clipless group had a lower mean analgesic requirement (7.5 versus 15.3 mg. morphine sulfate equivalent, p = 0.02), lower mean pain and scar scores (3.1 versus 5.3 and 1.1 versus 4.2, respectively, p <0.05) and more rapid convalescence (1.6 versus 3.3 weeks, p <0.01) but longer operative time (183 versus 136 minutes, p = 0.04). Similar blood loss, time to oral intake and hospital stay were noted in the 2 groups. No major complications, open conversions or postoperative secondary bleeding occurred in either group. A 2 mm. port was converted to a 10 mm. port in only 1 case in the clipless group due to the inability to retract a bulky liver properly with a needlescopic instrument. CONCLUSIONS: Clipless laparoscopic adrenalectomy with needlescopic instruments is feasible for most benign adrenal tumors. In addition to the benefits of conventional laparoscopic surgery, clipless needlescopic laparoscopic adrenalectomy further decreased postoperative pain, shortened convalescence and improved wound cosmesis.

Intensive rehabilitation. Recent experience in a chronic disease hospital.

An intensive rehabilitation program for persons with severe physical disabilities was carried on over a two-year period in a 35-bed unit at Rancho Los Amigos Hospital, a chronic disease hospital.Eighty-five patients were released (69 adults, 16 children) from the program after an average stay of six and a half months. Seventy-one per cent of these were discharged to their homes and the remainder were transferred to convalescent wards so much improved that they required less care, even worked on the grounds. Over half of the adult patients discharged to their homes became employed, not counting the women who resumed housework.The average hospitalization for patients in the same hospital without this program is three and a half years. Thus, despite a much higher cost per day for the patients in the intensive rehabilitation program, the total cost is about $7,640 less per patient discharged from the hospital.In addition the shorter period in hospital helps meet the ever-increasing demand for chronic disease beds.

[Incidence of the onset of disability and recovery of functional autonomy among the very old after one year].

BACKGROUND: This article measures the survival rate and explores the changes in functional autonomy among both men and women over a one-year period in a sample of 272 subjects aged 80-85. METHODS: Data were taken from the Quebec Longitudinal Study on Aging, a multi-cohort prospective study focusing on health and quality of life. The sample comprises two sub-groups, namely disabled and autonomous subjects. Eligible participants were selected from the Quebec Health Insurance Plan (QHIP) file. However, to obtain the required number of participants, the sample was completed from eligible subjects who volunteered in response to TV, billboard and newspaper advertising about the project. The Functional Autonomy Measurement System (SMAF) was used to assess disability. The SMAF assesses functional disability in 5 domains: activities of daily living (ADL), mobility, instrumental activities (IADL), communication, and mental functioning. RESULTS: After one year, nearly 5% of the subjects had died and 72.5% were still autonomous, i.e., they had a score under 4.5 on the SMAF. The annual incidence of the onset of disability (including death, lengthy hospitalization, functional incapacities and cognitive deficits) was 20%. However, no difference was found between the sexes in regard to the risk of losing autonomy. The main areas where disability occurred among the previously autonomous subjects were, in order of importance, domestic tasks, mobility and communication. The study confirmed that it is possible to recover autonomy, even at this advanced age, particularly for women (11.2%), but less so for men (3.6%). CONCLUSION: This phenomenon of recovering functional autonomy suggests that octogenarians have a residual potential and confirms the effectiveness of preventive and curative measures and the benefits of interventions by community and family networks.

Comparison of costs between laparoscopic and open Nissen fundoplication: a prospective randomized study with a 3-month followup.

BACKGROUND: Laparoscopic antireflux surgery has replaced conventional operation despite the fact that currently no randomized trials have been published regarding its cost effectiveness. The objective of the present study was to compare costs and some short-term outcomes of laparoscopic and open Nissen fundoplication. STUDY DESIGN: Forty-two patients with documented gastroesophageal reflux disease were randomized between October 1995 and October 1996 to either laparoscopic (LNF) or open (ONF) Nissen fundoplication. Some short-term outcomes, Gastrointestinal Quality of Life Index (GIQLI) hospital costs, and costs to society were assessed. Followup was 3 months. RESULTS: Medians of operation times in the LNF and ONF groups were 98 min and 74 min, respectively. Hospital stay was 2.5 days shorter after laparoscopic operation (LNF 3 days versus ONF 5.5 days). Both operations were equally safe and effective, but the LNF group experienced significantly less pain and fatigue during the first 3 postoperative weeks. Improvement in the GIQLI and overall patient satisfaction were comparable between the methods. Convalescence was faster in the LNF group: return to normal life being 14 versus 31 days and return to work being 21 versus 44 days in the LNF and ONF groups, respectively. Hospital costs were similar, $2,981 and $3,140 in the LNF and ONF groups, respectively, but total costs were lower ($7,506 versus $13,118) in the LNF group as a result of an earlier return to work. CONCLUSIONS: LNF is superior in cost effectiveness, assuming that the longterm results between the methods are comparable.

Clinical features of sporadic Campylobacter infections in Norway.

To assess risk factors and clinical impact of campylobacteriosis in Norway, a case-control study of sporadic cases of infection with thermotolerant Campylobacter spp. was conducted. This report describes: (1) the frequency and duration of signs and symptoms, antimicrobial treatment, hospitalization, and faecal carriage among the study patients; (2) diarrhoeal illness and campylobacter carriage among their household members; and (3) antimicrobial susceptibility pattern among bacterial isolates. A total of 135 patients with bacteriologically confirmed campylobacter infection were enrolled in the study. Of these, 58 (43%) were domestically acquired while 77 (57%) were acquired abroad. If the study enrollees are representative of the cases reported to the national surveillance system, the reported infections led to an estimated annual average of at least 8590 days of illness, 78 admissions to hospital, 329 days of hospital stay, 2236 days lost at work or at school, 1000 physician consultations, and 96 antimicrobial prescriptions among the 4.2 million Norwegians. Convalescent carriage of campylobacter was detected in 16% of the patients who submitted follow-up stool specimens; the organism was carried for a mean of 37.6 days (median 31, range 15-69) after the onset of illness. Antimicrobial treatment appeared to have reduced the likelihood of carriage once symptoms had resolved. Diarrhoeal illness was more commonly reported in members of case households than control households (OR = 5.44, p < 0.0001). Cases were more likely than controls to report antecedent recurrent diarrhoea (OR = 6.00, p = 0.034). Two cases of neonatal infection, probably acquired from the mother at the time of delivery, were detected.(ABSTRACT TRUNCATED AT 250 WORDS)

Heart rate variability in early phase of acute myocardial infarction and convalescence.

OBJECTIVE: This study was done to evaluate the degree of change in autonomic activity, manifested as heart rate variability (HRV), from acute phase of MI to convalescent period of AMI. DESIGN: Single center, observational prospective study. PLACE AND DURATION OF STUDY: Department of Cardiology, Shaikh Zayed Hospital, Lahore. The study was completed in one year from June 2000 to July 2001. SUBJECTS AND METHODS: Thirty consecutive patients presenting within 24 hours of an ST segment elevation AMI with or without thrombolysis were included. First 24 hour Holter recording was done within 24-36 hours after AMI and the second was done before discharge. RESULTS: The mean hospital stay was 7.07 +/- 2.56 days. Mean duration between the two recordings was 5.47 +/- 2.36 days. The mean standard deviation of normal sinus interval (SDNN) was 65.07 +/- 25.11msec & 63-97 +/- 23.38msec; mean standard deviation of averaged sinus beats for 5 minutes segments of entire recording (SDANN) was 51.27 +/- 18.57msec and 55.83 +/- 19.65msec and mean SDDN index was 34.57 +/- 17.15msec and 30.57 +/- 14.89msec during early phase of acute MI & pre-discharge recordings respectively. There was no statistically significant difference in HRV between early phase of acute myocardial infarction and of pre-discharge recordings. CONCLUSION: HRV may be monitored for risk stratification at any time post AMI prior to discharge.

Detection of IgM antibodies specific for measles virus by capture and indirect enzyme immunoassays.

During a measles outbreak, 112 serum specimens from 88 hospitalized patients were received in our laboratory for investigation of a morbilliform rash. These specimens (88 acute- and 24 convalescent-phase) were tested for the presence of measles-specific IgM antibodies by a capture EIA (enzyme immunoassay) using peroxidase-conjugated measles virus antigens and by an indirect EIA. Commercially available indirect EIA kits for measles-specific IgM antibodies were also used and compared with our homemade EIAs. Specificity studies included a collection of serum specimens containing rheumatoid factor, antinuclear antibodies or IgM antibodies specific to other viruses, and sera from blood donors and healthy children. Sensitivity of capture EIA and indirect EIA to detect measles IgM was 91.8 and 90.3%, respectively, and specificity was 98.2% for both tests. Specific IgM antibodies were detected in 70.5% of serum specimens at the first day after rash onset and were present for a month following the rash. Among the commercial measles IgM detection assays, EIA "Behring" was found to be a valid alternative for detection of measles virus-specific IgM.

Toscana virus infections of the central nervous system in children: a report of 14 cases.

OBJECTIVE: To evaluate the pathogenicity of a recently discovered arthropod-transmitted bunyavirus (Toscana virus) on the CNS in children and to provide information on the epidemiologic and clinical aspects of Toscana virus infection. STUDY DESIGN: Case-series analysis of children hospitalized with clinical and cerebrospinal fluid examination compatible with a CNS disease of viral origin. METHODS: Cerebrospinal fluid, acute, and convalescent sera were investigated for conventional neurotropic viruses and for Toscana and tickborne encephalitis viruses. A clinical-epidemiologic analysis was carried out on confirmed Toscana virus cases to clarify the profile of Toscana virus infection in children. RESULTS: The study indicates that (1) Toscana virus has been endemic in the Siena province for at least 15 years; (2) the virus is responsible for at least 80% of acute viral infections of the CNS in children throughout the summertime; (3) the clinical signs and symptoms range from aseptic meningitis to meningoencephalitis; (4) infected children resided habitually or temporarily in rural or suburban areas of the Siena province, where ecological characteristics allow arthropods to be peridomestic in human settlements. CONCLUSIONS: Toscana virus is the most common viral agent involved in acute infections of CNS in children in central Italy.

Intact specimen extraction during renal laparoscopy: muscle-splitting versus muscle-cutting incision.

PURPOSE: To determine whether a muscle-splitting extraction incision decreases patient morbidity after renal laparoscopic surgery. PATIENTS AND METHODS: Twenty-one patients undergoing laparoscopic simple nephrectomy, radical nephrectomy, or nephroureterectomy had intact specimen extraction through a muscle-splitting incision. The operative and recovery data of these patients were retrospectively compared with those of a matched cohort of 21 patients who underwent specimen extraction through a muscle-cutting incision. With the exception of a greater percentage of male patients in the muscle-cutting group (86% v 52%), there were no statistically significant differences between the two groups. RESULTS: In the muscle-splitting and muscle-cutting groups, there was no significant differences in regard to analgesic use (9.0 +/- 6.6 mg of morphine sulfate equivalent v 7.9 +/- 4.9; P < 0.51), hospital stay (31.2 hours v 30 hours; P < 0.79), recovery (6.7 +/- 4.7 days v 5.7 +/- 4.7 days; P < 0.38), or convalescence (4.2 +/- 2.2 weeks v 4.1 +/- 2.0 weeks; P < 0.90). CONCLUSION: A muscle-splitting incision for intact renal specimen extraction does not necessarily decrease postoperative morbidity compared with a muscle-cutting extraction.

Antioxidant protection against iron in children with meningococcal sepsis.

OBJECTIVE: To assess antioxidant protection against iron-catalyzed reactive oxygen species in meningococcal sepsis and to establish whether severity of illness is related to deficiencies in these antioxidant systems. DESIGN: Prospective, controlled study. SETTING: Pediatric intensive care unit of a postgraduate teaching hospital. PATIENTS: Twenty children aged 6 months to 15 yrs (median, 5 yrs) with meningococcal septic shock were studied. Paired convalescent samples taken 8-10 wks after discharge were available in nine children. INTERVENTIONS: Routine management for meningococcal sepsis. MEASUREMENTS AND MAIN RESULTS: Patients were classified for disease severity using the Glasgow Meningococcal Septicaemia Prognostic Score. Paired acute and convalescent samples were compared. Transferrin level (1.77 +/- 0.08 g/L) and total iron-binding capacity (46.2 +/- 2.0 microM) were significantly decreased in acute patients compared with paired convalescent samples (2.85 +/- 0.10 g/L and 74.4 +/- 2.5 microM, respectively; p <.0001). The iron saturation of transferrin was significantly increased in acute disease (36.9% +/- 2.5%) compared with convalescence (18.8% +/- 1.5%; p =.0003). Iron-binding antioxidant protection was not significantly different in acute (81.4% +/- 1.7%) and paired convalescent samples (85.6% +/- 2.5%; p =.54). However, patients with more severe meningococcal septicemia (GMSPS, >10; n = 12) had significantly diminished protection (77.5% +/- 2.4%) compared with less severe disease (87.1% +/- 1.6%; p =.0028), and there was a significant correlation between disease severity and iron-binding antioxidant protection (R =.48; p =.00067) in acute disease. Paired ceruloplasmin levels were available in six patients and were decreased in acute disease (0.29 +/- 0.02 g/L) compared with convalescence (0.40 +/- 0.04 g/L), although not statistically significant (p =.076). However, there was a significant correlation between plasma ceruloplasmin and disease severity (Pearson product moment correlation, p =.038) in the acute patients. Iron-oxidizing antioxidant assays were performed in four paired samples and were diminished in acute patients (53.3 +/- 4.4%) compared with convalescence (67.8 +/- 3.2%; p =.015). Acute samples demonstrated a significant relationship between iron-oxidizing antioxidant protection and both disease severity (r =.30; p =.012) and plasma ceruloplasmin levels (r =.48; p =.00067). CONCLUSIONS: Children with meningococcal septicemia exhibit abnormal plasma iron chemistry and decreased protection against iron-catalyzed oxidative damage. Such deficiencies correlate with disease severity.

Effect of standard rest periods on convalescent preterm infants.

OBJECTIVE: To examine the effects of standardized rest periods on the sleep-wake states of preterm infants who were convalescing. DESIGN: A randomized experimental study conducted from time of infants' entry into intermediate care until their discharge from the hospital. Because subjects' time in this study varied, data were analyzed cross-sectionally using the observation made between 5-11 days of the study and longitudinally over 3 weeks using a subset of subjects. SETTING: The intermediate care nursery of a tertiary care hospital. SUBJECTS: Forty-six preterm infants (23 matched pairs). A subset of 12 pairs, in which infants in the experimental and the control groups were in the study for 3 weeks, was analyzed longitudinally. INTERVENTIONS: Four standardized rest periods each day. MAIN OUTCOME MEASURES: Infants were observed once a week between noon and 8 p.m. Three sleep-wake states--quiet awake, active, and sleep--were measured as percentages of the naps and total observation. RESULTS: Within 5 days, infants in the experimental group exhibited more sleep (F[1,44] = 2.37, p < 0.05) and less active states (F[1,44] = 3.06, p < 0.01) during nap time. Infants receiving the intervention for 3 weeks had more sleep (F[1,22] = 4.63, p < 0.05) and less quiet waking states (F[1,22] = 13.85, p < 0.01) during naps. State patterns over the entire observation did not differ between the groups at 5 days, but by 3 weeks, infants in the experimental group had less quiet waking (F[1,22] = 17.44, p < 0.001) and longer uninterrupted sleep bouts (F[1,22] = 5.19, p < 0.05). CONCLUSIONS: A simple modification of nursing care had an impact on the sleeping and waking states of preterm infants.

Evaluation of streptozyme and antistreptolysin O tests in streptococcal pyodermal nephritis.

The evaluation of the streptozyme test in sera from 34 patients with streptococcal pyodermal nephritis was studied. Ninety-seven percent of the patients developed high titers of antistreptozyme antibodies on the first bleeding after hospitalization, in contrast to only 40% of patients who developed elevated antistreptolysin O titers. The high antistreptozyme titers declined during convalescence and reached normal levels in the sixth month after onset of the disease. The most significant fall in titers occurred between 1 and 2 months from the onset of disease. The streptozyme test may be particularly helpful as a rapid screening test for antibodies in streptococcal pyodermal nephritis.

Does gender affect outcome of cardiac surgery in octogenarians?

The long-term results of cardiac surgery in 212 consecutive octogenarians (116 men, 96 women) were reviewed retrospectively. Preoperative functional status, Euroscore, and the incidences of hypertension and chronic obstructive pulmonary disease were similar in both sexes. Women had more diabetes mellitus (45% versus 25%; p < 0.05) but less renal dysfunction (16% versus 29%; p < 0.05). Men required emergency procedures more frequently (p < 0.05). Women underwent complete revascularization more often and had more arterial grafts. Hospital mortality was similar (11.5% in women versus 12.9% in men), but women had more complications (76% versus 64%), longer convalescence (24.3 versus 18.5 days), fewer psychiatric disorders (14% versus 23%) and less heart block (9% versus 19%). Men had a slightly better outcome in terms of functional class and Euroqol score during follow-up of up to 114 months. Median survival was longer in women (3.15 versus 2.96 years) but 1-, 3-, and 5-year survival rates and late deaths were similar. Outcomes appear to be equitable for both sexes among octogenarians.

Influence of median sternotomy on the psychosomatic outcome in coronary artery single-vessel bypass grafting.

OBJECTIVES: New less invasive surgical techniques for the treatment of coronary artery single-vessel disease have been developed by either avoiding median sternotomy or cardiopulmonary bypass or both, however, until now no prospective randomized trial has been carried out to compare these techniques to the conventional approach with special respect to the psychosomatical effects. METHODS: In a prospective randomized trial four different surgical techniques were compared. Group 1: conventional technique (median sternotomy, cardiopulmonary bypass) in ten patients (eight male, two female, age 59.6 +/- 11.0 years); Group 2: off-pump coronary artery bypass with median sternotomy in nine patients (six male, three female, age 65.7 +/- 11.1 years); Group 3: lateral minithoracotomy and cardiopulmonary bypass in eight patients (five male, three female, age 62.3 +/- 9.9 years). Group 4: off-pump procedure and lateral minithoracotomy in nine patients (eight male, one female, age 63.8 +/- 11.3 years). All patients due to coronary artery single-vessel disease. The tests used for psychosomatic situation were post-traumatic stress disorders scale, pain behavior rating scale, pain visual analog scale, and 6' walking-distance. For detection of false results due to surgical technical failures 3-month follow-up was undertaken including echocardiography and coronary angiogram. RESULTS: There were no deaths or major complications. Operative time was longer in lateral minithoracotomy procedures, but intensive care unit stay and hospitalization were equal in all groups. Pain visual analog scale and pain behavior rating scale showed a peak on post-operative day 4 in median sternotomy procedures. Post-traumatic stress disorder scale revealed higher values on post-operative day 4 and equalizing with lateral minithoracotomy procedures 1 month post-operatively. Six-minutes walking distance on post-operative day 4 was longer in the group with lateral minithoracotomy. Three-month follow-up revealed patency of all grafts. CONCLUSIONS: Even if surgery is successful in all procedures, operative time is longer in lateral minithoracotomy procedures without compromising intensive care unit stay and hospital stay. More pain with multiple post-traumatic stress disorders is related to median sternotomy, and post-operative convalescence is superior for lateral minithoracotomy procedures.
