Outcomes of Foot and Ankle Surgery in Diabetic Patients Who Have Undergone Solid Organ Transplantation

The association of chronic, enhanced immunosuppression with outcomes of diabetic foot infections

We investigated if a chronic, enhanced immunosuppressed condition, beyond the immunodeficiency related to diabetes, is associated with clinical failures after combined surgical and medical treatment for diabetic foot infection (DFI). This is a case-control cohort study in a tertiary centre for diabetic foot problems, using case-mix adjustments with multivariate Cox regression models. Among 1013 DFI episodes in 586 patients (median age 67 years; 882 with osteomyelitis), we identified a chronic, enhanced immune-suppression condition in 388 (38%) cases: dialysis (85), solid organ transplantation (25), immune-suppressive medication (70), cirrhosis (9), cancer chemotherapy (15) and alcohol abuse (243). Overall, 255 treatment episodes failed (25%). By multivariate analysis, the presence (as compared with absence) of chronic, enhanced immune-suppression was associated with a higher rate of clinical failures in DFI cases (hazard ratio 1.5, 95% confidence interval 1.1-2.0). We conclude that a chronic, enhanced immune-suppressed state might be an independent risk factor for treatment failure in DFI. Validation of this hypothesis could be useful information for both affected patients and their treating clinicians.

Complications and safety of the transplanted organ after upper extremity surgery in patients receiving immunosuppressant therapy after solid organ transplantation

PURPOSE

The purpose of this study was to evaluate the complications and safety of transplanted organs after upper extremity surgery in patients taking immunosuppressants after solid organ transplantation (SOT).

METHODS

Seventy-two transplant recipients underwent 99 upper extremity surgeries while on immunosuppressants after SOT at our institution between January 2009 and December 2018. We retrospectively reviewed the clinical data of these patients, including their demographic information and data related to the SOT and upper extremity surgery.

RESULTS

Trigger/tendon release (n = 31, 31.3%) was the most frequently performed upper extremity surgery, followed by incision and drainage for an infection (n = 16, 16.2%). Post-operative complications occurred after ten upper extremity operative procedures (10.1%), among which uncontrolled infection after surgery for an infection (n = 4) was the most common. According to the Clavien-Dindo classification, the complications of three surgical procedures were grade I, three were grade II, and four were grade III, and all were treatable. The occurrence rate of the complications was not significantly different between emergent and elective surgery. All transplanted organ-specific indicators did not worsen significantly after emergent or elective upper extremity surgery.

CONCLUSIONS

Since the function of the transplanted organ was well-preserved after emergent or elective upper extremity surgery, common upper extremity procedures do not seem to be a worrisome practice for SOT patients. However, when treating hand and upper extremity infections in SOT patients, surgeons should explain the possible need for multiple operations  and the high complication rate.

Risk factors for admission after shoulder arthroscopy

BACKGROUND

Shoulder arthroscopy is a common orthopedic procedure typically performed on an outpatient basis. Occasionally, patients require an unplanned hospital admission. An understanding of the incidence and risk factors for admission after shoulder arthroscopy may assist surgeons in determining which patients may be susceptible to unplanned admission after surgery.

METHODS

All consecutive shoulder arthroscopy procedures performed during a 10-year period were reviewed. A 2:1 control-case matching technique was used. Univariate analysis was performed to identify differences between patients admitted after surgery and the control group. Multivariate analysis was performed to identify variables associated with admission.

RESULTS

There were 5598 arthroscopic shoulder procedures performed, with 233 patients (4.2%) requiring admission. The most common reason for admission was respiratory monitoring. Risk factors for admission by multivariate analysis were chronic obstructive pulmonary disease (odds ratio [OR], 2.73; 95% confidence interval [CI], 1.51-4.95), diabetes (OR, 2.11; 95% CI, 1.28-3.48), obstructive sleep apnea (OR, 1.90; 95% CI, 1.13-3.21), age (OR, 1.02; 95% CI, 1.01-1.04), body mass index (OR, 1.04; 95% CI, 1.01-1.07), and operative time (OR, 1.01; 95% CI, 1.00-1.01). Regional with monitored anesthesia care decreased risk compared with general anesthesia and regional with general anesthesia (OR, 0.44; 95% CI, 0.30-0.63).

CONCLUSION

Chronic obstructive pulmonary disease, obstructive sleep apnea, diabetes, increasing age, increasing body mas index, and increasing operative time were all risk factors for admission after shoulder arthroscopy. The absence of general anesthesia was found to decrease the risk of admission.

Treating Charcot Arthropathy Is a Challenge: Explaining Why My Treatment Algorithm Has Changed

Charcot deformity is a challenge that foot and ankle surgeons struggle to manage successfully. Despite the advances in knowledge, technology, and treatment modalities, limb loss is still greater than 10%. This article discusses the efficacy of conservative measures and traditional surgical approaches. It proposes a multidisciplinary team approach, medical optimization, and lifestyle modification to put the patient in the best position to heal. Also discussed is the authors' staged surgical treatment protocol to enhance outcomes and decrease the rate of limb loss.
