Satisfactory functional and MRI outcomes at the foot and ankle following harvesting of full thickness peroneus longus tendon graft.

AIMS: To evaluate the donor site morbidity and tendon morphology after harvesting whole length, full-thickness peroneus longus tendon (PLT) proximal to the lateral malleolus for ligament reconstructions or tendon transfer. METHODS: A total of 21 eligible patients (mean age 34.0 years (standard deviation (SD) 11.2); mean follow-up period 31.8 months (SD 7.7), and 12 healthy controls (mean age, 26.8 years (SD 5.9) were included. For patients, clinical evaluation of the donor ankle was performed preoperatively and postoperatively. Square hop test, ankle strength assessment, and MRI of distal calf were assessed bilaterally in the final follow-up. The morphological symmetry of peroneal tendons bilaterally was evaluated by MRI in healthy controls. RESULTS: Among the patients, the mean pre- and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and Karlsson-Peterson score were 98.7 (SD 2.5; p = 0.480) and 98.5 (SD 2.4; p = 0.480), and 98.3 (SD 2.4; p = 0.162) and 97.9 (SD 2.5; p = 0.162), respectively. There was no significant difference between square hop test bilaterally (p = 0.109) and plantar flexion peak force bilaterally (p = 0.371). The harvested limb had significantly less eversion peak force compared to the contralateral limb (p < 0.001). Evidence of probable tendon regeneration was observed in all the patients by MRI and the total bilateral peroneal tendon index (mean ratio of harvested side cross-sectional area of peroneal tendon compared with the contralateral side) was 82.9% (SD 17.4). In 12 healthy controls, peroneal tendons (mean 99.4% (SD 4.3) were found to be morphologically symmetrical between the two sides. CONCLUSION: The current study showed satisfactory clinical foot and ankle outcomes after full-thickness PLT harvesting and indicated the regenerative potential of PLT after its removal. Level of Evidence: Level IV, therapeutic retrospective case series. Cite this article: Bone Joint J 2020;102-B(2):205-211.

Efficacy of Follow-up Care System of Living Kidney Donors in Monitoring of Residual Kidney Function.

BACKGROUND: The possibility of an increased risk of end-stage renal disease is a major concern associated with living kidney donation. Therefore, monitoring of residual kidney function becomes most essential. METHODS: A data analysis of 156 living kidney donors (LKDs) was conducted. The efficacy of the long-term care system with regard to monitoring residual kidney function was evaluated. RESULTS: The analyzed group consisted of 102 (65.4%) women. The mean follow-up period was 5.44 years. The rise in value of mean serum creatinine concentration after donation was observed, but it was within the range of normal during the observation period. Despite its initial decline after nephrectomy, mean glomerular filtration rate (GFR) remained >60 mL/min/1.73 m2. A MDRD (Modification of Diet in Renal Disease) GFR in the range of 45-60 mL/min/1.73 m2 was observed in 53 donors (33.97%). It was found to be <45.0 mL/min/1.73 m2 in 15 cases (9.6%). No patient developed end-stage renal disease. Only 25.0% of those analyzed had their CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) GFR estimated on 45-60 mL/min/1.73 m2 and 4.49% were found to have levels of <45 mL/min/1.73 m2 (down to 33.7 mL/min/1.73 m2). Mean postdonation CKD-EPI GFR was estimated at 69.99% of its predonation value. CONCLUSION: A reliable qualification process could minimize the probability of kidney donation by someone with an increased risk of chronic kidney failure. The CKD-EPI formula seems to be more precise than the MDRD for estimatation of LKDs' GFR, as their loss of GFR is a result of nephrectomy and not kidney or systemic disease. Using the MDRD formula may lead to inappropriate diagnosis of CKD in some cases.

Quality of Life After Living Donor Hepatectomy for Liver Transplantation.

BACKGROUND: Living donor liver transplantation (LDLT) involves healthy individuals undergoing voluntary major hepatic resection. LDLT program only started in 2012 in Pakistan and its impact on donor's quality of life (QOL) post resection is not known. The objective of this study was to determine health-related QOL in donors who underwent hepatectomy in country's first liver transplant program. METHODS: A total of 60 donors who underwent hepatectomy between 2012 and 2014 with a minimum follow-up of 6 months were included in the study. Short form (SF-36) and Profile of mood states (POMS-65) was used to assess QOL. In addition scores were compared between patients who did and did not develop complications. RESULT: Mean time duration between hepatectomy and administration of questionnaire was 15 ± 5.1 months. Median age was 28 (19-45) years. Mean BMI was 24.4 ± 3.7. A total of 7 (11.6%) Grade 3 and above complications were observed in donors. Donors exceeded a score of 90 in 6 out of 8 evaluated categories on SF-36. The highest mean score was recorded for emotional role limitation 95.5 ± 17.1 and lowest for energy 84.8 ± 17.5. The mean score for anger was 6.6 ± 7.5. Donors also did well on the POMS vigor score with a mean of 22.7 ± 5. No significant difference in scores was observed between donors with and without complications for any of the categories except tension. Donors who developed complications post-operatively had a significantly low mean tension score of 1.5 versus 3.8 for donors without complications. CONCLUSION: Acceptable post donation QOL was achieved and surgical complications did not adversely affect SF-36 and POMS scores.

[The first successful adult right-lobe living donor liver transplantation in Hungary]. / Az elsô sikeres élô donoros felnôttkori jobb lebenyes májtranszplantáció Magyarországon.

The authors report on their experiences related to the first adult live donor liver transplantation performed in Hungary. The transplantation was done between brother and sister on 19th of November, 2007. The right lobe of the 33-year-old healthy male's donor liver (segments 5-8) was removed and implanted into the 23-year-old female suffering from cirrhosis on the ground of autoimmune hepatitis. The implantation of the right liver lobe was done after own hepatectomy in orthotopic position. Liver function has improved rapidly following the transplantation. The donor was discharged on the 10th post-operative day with stable liver function. He had full rehabilitation, got back to work, and control check-ups showed a significant liver regeneration. Two years after transplantation, the recipient also lives an active life with compensated liver function and she is under regular medical check-up. With the case report, authors overview the indications and techniques of living donor right-lobe liver transplantation.

Reconstruction of epidermis by grafting of keratinocytes cultured on polymer support--clinical study.

BACKGROUND: Extensive wound coverage still represents a challenge for contemporary medicine. We demonstrate the results of a clinical trial of the grafting of cultured keratinocytes directly on a polymer cultivation support in the treatment of skin defects in seriously burned patients and in patients with trophic ulcers. METHODS: Wound closure was evaluated clinically. The morphology and phenotypic pattern of the reconstructed epidermis, including the basal lamina, as well as the presence of Langerhans cells, were evaluated immunocytochemically using a panel of monoclonal antibodies. RESULTS: All layers of the reconstructed epidermis were normally differentiated (cytokeratin immunocytochemistry). The basal lamina contained collagen type IV and laminin. The reconstructed epidermis was extensively colonized by Langerhans cells. CONCLUSIONS: The results of the described technology are encouraging, especially in patients after a burn injury. The described procedure is suitable for the treatment of skin defects in clinical practice.

[Replacement of the anterior cruciate ligament with a patellar tendon transplant]. / Ersatz des vorderen Kreuzbandes mit dem Patellarsehnentransplantat.

The bone-patellar tendon-bone graft (BTPB) was the most commonly used graft for many years. The scientific database is more complete than for every other graft option. This review article presents the surgical techniques of ACL reconstruction with the BPTB graft, aspects of rehabilitation, clinical results, and postoperative problems with special emphasis on donor site morbidity.

Living kidney donation: a comparison of laparoscopic and conventional open operations.

Laparoscopic donor nephrectomy has the potential to lessen the burden placed on live kidney donors. This study describes the first British comparison of donor morbidity and recovery following conventional open donor nephrectomy (ODN) and laparoscopic donor nephrectomy (LDN). An initial series of LDN (n=20) was compared to a historical control group of ODN (n=34). Laparoscopic operations were performed via a transperitoneal approach, the kidney being removed through a 6--12 cm Pfannensteil incision. Open operations were performed using a retroperitoneal flank approach with resection of the 12th rib. Postoperatively, donors were managed with a patient controlled analgesia system. LDN was associated with shorter mean (SD) inpatient stay (6 (2) v 4 (1) days; p=0.0001) and lower parenteral narcotic requirements (morphine 179 (108) v 67 (54) mg; p=0.0001). Laparoscopic donors started driving their cars sooner (2 (1.5) v 6 (4) weeks; p=0.0001) and returned to work more quickly (5 (3) v 12 (6) weeks; p=0.0001) than open nephrectomy donors. There were no differences in recipient serum creatinine levels at three months post-transplant but two recipients of transplant kidneys retrieved laparoscopically (10%) developed ureteric obstruction, whereas this complication did not occur after ODN (p=0.13). LDN is associated with less postoperative pain and a substantial improvement in donor recovery times. It is not yet clear whether or not the outcome of the recipient kidney transplants are the same after ODN and LDN and much more experience is required before the place of this new technique can be defined.

A retrospective comparison of abdominal muscle strength following breast reconstruction with a free TRAM or DIEP flap.

Abdominal weakness is a known potential complication of breast reconstruction with a pedicled or free TRAM flap. It has been presumed that the DIEP flap, which involves no muscle resection, does not compromise abdominal muscle strength but little objective research exists to substantiate this. The aims of this retrospective study were to compare abdominal muscle strength following free TRAM flap and DIEP flap, to compare both groups with a control group and to establish the effect of both procedures on functional activities. Fifty women (23 with a DIEP flap, 27 with a free TRAM flap) plus 32 non-operated controls underwent assessment of their abdominal and back extensor muscle strength on a KIN COM isokinetic dynamometer. Two questionnaires were used to establish the impact on function. The TRAM flap group had significant weakness of the abdominal and back extensor muscles compared with the DIEP flap group and the control group. The trend was for the DIEP flap group to have weaker abdominal muscles than the control group. There was a higher level of abdominal pain and a greater number of reported functional difficulties in the TRAM flap group than in the DIEP flap group. This study demonstrates that whilst the DIEP flap can reduce the strength deficit caused by the free TRAM flap, abdominal weakness can still result from the DIEP flap. A randomised controlled trial is currently underway to investigate the effect of preoperative abdominal exercises in preventing/minimising postoperative abdominal muscle weakness in this group.
