Porous Tantalum Metaphyseal Cones for Severe Femoral and Tibial Bone Defects in Revision Total Knee Arthroplasty are Reliable for Fixation at Mean 5-Year Follow-Up

BackgroundPorous tantalum metaphyseal cones may facilitate reconstructions of severe bone defects during revision total knee arthroplasty (TKA), but there remains a paucity of data on their outcomes at mean 5 years of follow-up. This study reports the component survivorship, patient satisfaction, functional outcomes, radiographic osseointegration, and complications of revision TKA with porous tantalum metaphyseal cones at mid-term (mean 5-year) follow-up. MethodsThis study included 152 patients who had a mean age of 66 years (range, 33 to 86 years) undergoing revision TKA with porous tantalum metaphyseal cones. Indications for surgery included aseptic loosening (n = 87, 57.3%), second-stage reimplantation for infection (n = 42, 27.6%), osteolysis with well-fixed components (n = 20, 13.2%), and periprosthetic fracture (n = 3, 2.0%). Component survivorship, clinical outcomes, radiographic outcomes, and any complications were recorded. The mean follow-up time was 5.6 years (range, 2.2 to 13.7). ResultsSurvivorship was 100% when the end point was revision of the metaphyseal cone (no cones were revised) and 83.8% (95% confidence interval: 77.9 to 90.2%) when the end point was reoperation for any reason at 5-year follow-up. Reoperations were performed for infection (n = 10), instability (n = 4), periprosthetic fracture (n = 2), and quadriceps rupture/dehiscence (n = 3). The mean patient satisfaction score was 78.8 ± 11.3 and the mean Forgotten Joint Score was 62.2 ± 16.7 at the final follow-up. The preoperative median University of California at Los Angeles score improved from 2 (interquartile range 2 to 3) to 6 points (interquartile range 5 to 6) (P < .001), and the preoperative Oxford knee score improved from 15.2 ± 3.8 to 39.4 ± 5.1 points (P < .001) at the final follow-up. All metaphyseal cones showed radiographic evidence of osteointegration without any subsidence or loosening. ConclusionsPorous tantalum metaphyseal cones enabled robust reconstructions of severe femoral and tibial bone defects during revision TKA. These reconstructions were associated with excellent survivorship, improvements in functional outcomes, and reproducible radiographic osseointegration at mean 5-year follow-up. The most common reasons for reoperation were infection and instability.

Revision Dual Mobility Constructs With Unmatched Acetabular and Femoral Components Do Not Increase Failure Rate

BackgroundDual mobility (DM) constructs for revision total hip arthroplasty (THA) have continued to grow in popularity to mitigate instability. This benefit comes at the cost of potential unique modes of failure, and there are theoretical concerns that combining femoral and acetabular components from different manufacturers could lead to increased failure rates. We aimed to investigate rates of reoperation between matched and unmatched DM implants used in revision THA. MethodsWe retrospectively reviewed 217 revision THAs performed with DM constructs between July 2012 and September 2021 at a single institution. Dual mobility (DM) constructs were classified as “matched” if the acetabular and femoral components were manufactured by the same company. They were classified as “unmatched” if the acetabular and femoral components were manufactured by different companies. The primary outcome was reoperation for any reason. ResultsThere were 136 matched DM constructs and 81 unmatched constructs. Average follow-up was 4.6 years (range, 2.0 to 9.6 years). There was no difference in reoperation rate between matched and unmatched groups (11.0 versus 13.6%, P = .576). The most common reasons for reoperation in both groups were instability and periprosthetic joint infection. There was 1 revision for intraprosthetic dislocation in the matched group. ConclusionsThe use of unmatched DM components in revision THA was common and did not increase the risk of reoperation at an average of 4.6-year follow-up. This information can be helpful in operative planning, but further research on long-term survival will be necessary.

Current Concepts: Corrective Osteotomy for Extra-Articular Deformity Following a Distal Radius Fracture.

Fracture malunion alters wrist and distal radioulnar joint (DRUJ) biomechanics, resulting in incongruence and instability of the DRUJ. Selected patients with painful functional limitation and significant deformity of the radius, but without advanced degenerative joint disease, may benefit from corrective distal radial osteotomy. Non-union and complications arising from metalwork are the most common reasons for reoperation. Surgeons should have a good understanding of risks and complications in order to fully inform their patients and manage expectations. This article reviews the biomechanical effects of radial malunion and the current concepts for treatment. Distal radial osteotomy is suitable for symptomatic patients with angular radial deformity and shortening. Evidence supports a volar approach without bone grafts for modest corrections. Bone grafts or synthetic bone substitutes are appropriate for larger corrections. Functional improvements are reported regardless of technique. Despite a high complication rate, patient satisfaction with the corrective radial osteotomy is high.

Minimally invasive tubular microdiscectomy for recurrent lumbar disc herniation: step-by-step technical description with safe scar dissection

IntroductionRecurrent lumbar disc herniation (RLDH) is one of the most common reasons for re-operation after primary lumbar disc herniation with an incidence ranging from 5 to 23%. Numerous RLDH studies have been conducted; however, no available studies have provided a specific description of the use of the tubular retractor discectomy technique for RLDH emphasizing safe scar dissection. The objective of this study is to describe a detailed step-by-step technique for RLDH.Material and methodsA surgical technique reporting on our experience from the year 2013–2021 in 9 patients with RLDH at the same level and same side was included in the study. Clinical outcomes were assessed using the visual analog score (VAS) for leg pain before and three months after surgery.ResultsA significant improvement was observed between the preoperative and postoperative VASs [mean (SD): 9.2 (1) vs. 1.5 (1)] for all patients. We did not report any incidental durotomy, neurological deficits or mortality in this study. One patient had superficial wound infection. The study is limited by small population, short follow-up and not reporting stability or spondylolisthesis.ConclusionA modified tubular discectomy technique with safe scar dissection is effective for RLDH treatment. Technically, the only scar needed to be dissected is the scar lateral to the exposed normal dura and the scar extended caudally till the level of the superior end plate of the targeted disc space where the scar can be entered ventrally and the disc fragment retrieved. Adherence to the step-by-step procedure described in our study will help surgeons operate with more confidence and minimize complications of recurrent lumbar disc herniation.

15-Year Follow-Up of Mobile Bearing Medial Unicompartmental Knee Arthroplasty

IntroductionMedial unicompartmental knee arthroplasty (UKA) is a successful treatment for antero-medial osteoarthritis. However, there are few published studies on the long-term survival of this procedure. The purpose of this study was to review the 15-year minimum outcomes and survival of a mobile-bearing medial UKA. MethodsA retrospective review was performed between July 2004 and December 2006 of all patients who underwent a medial UKA eligible for a minimum of 15-year follow-up. The initial query revealed 299 patients (349 knees). One hundred-seventeen patients died or were lost to follow-up, leaving 182 patients (219 knees) for analyses. Clinical outcomes and survivorship were analyzed. ResultsThere were 59 implant-related reoperations which occurred at a mean of 10 years (range, 0 to 16 years). The most common reasons for reoperation were arthritic progression (9.1%) and aseptic loosening (9.1%). The 10-year survival with revision to TKA was 89% (95% confidence interval: 86% to 92.4%), and the 15-year survival was 84.1% (95% confidence interval: 80.3% to 88%). There were no statistically significant differences in survival between sex, body mass index, and age. Patients who were not revised had statistically significant improvements in knee range of motion and Knee Society scores. ConclusionsThis study found similar long-term survival of a medial mobile-bearing UKA to published total knee arthroplasty outcomes. The implant evaluated in this study has undergone subsequent improvements in instrumentation and design. Further analyses should be performed on the long-term outcomes of the current implant platform.

Do robot-related complications influence 1 year reoperations and other clinical outcomes after robot-assisted lumbar arthrodesis? A multicenter assessment of 320 patients

BackgroundRobot-assisted platforms in spine surgery have rapidly developed into an attractive technology for both the surgeon and patient. Although current literature is promising, more clinical data is needed. The purpose of this paper is to determine the effect of robot-related complications on clinical outcomesMethodsThis multicenter study included adult (≥18 years old) patients who underwent robot-assisted lumbar fusion surgery from 2012-2019. The minimum follow-up was 1 year after surgery. Both bivariate and multivariate analyses were performed to determine if robot-related factors were associated with reoperation within 1 year after primary surgery.ResultsA total of 320 patients were included in this study. The mean (standard deviation) Charlson Comorbidity Index was 1.2 (1.2) and 52.5% of patients were female. Intraoperative robot complications occurred in 3.4% of patients and included intraoperative exchange of screw (0.9%), robot abandonment (2.5%), and return to the operating room for screw exchange (1.3%). The 1-year reoperation rate was 4.4%. Robot factors, including robot time per screw, open vs. percutaneous, and robot system, were not statistically different between those who required revision surgery and those who did not (P>0.05). Patients with robot complications were more likely to have prolonged length of hospital stay and blood transfusion, but were not at higher risk for 1-year reoperations. The most common reasons for reoperation were wound complications (2.2%) and persistent symptoms due to inadequate decompression (1.5%). In the multivariate analysis, robot related factors and complications were not independent risk factors for 1-year reoperations.ConclusionThis is the largest multicenter study to focus on robot-assisted lumbar fusion outcomes. Our findings demonstrate that 1-year reoperation rates are low and do not appear to be influenced by robot-related factors and complications; however, robot-related complications may increase the risk for greater blood loss requiring a blood transfusion and longer length of stay.

Pediatric cerebral cysts: comparison of early complications following fenestration versus shunting procedures

ABSTRACT Objective: Characterize practice patterns and acute (30-day) surgical complications following fenestration and shunt procedures for the treatment of cerebral cysts in pediatric patients. Methods: This study utilized the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Pediatric database. Patients were identified by International Classification of Disease codes for cerebral cysts and Current Procedural Terminology codes for shunting or fenestration. Demographic data, preoperative comorbidities, and postoperative complications were compared between the two procedures. Results: 741 patients were included in the data analysis, with a majority aged 4 years or younger (55.9%) and a male predominance (62.6%). Fenestration was performed in 590 (79.6%) patients. Primary shunting was performed in 151 (20.4%) patients. Patients who received shunts were more commonly aged 0–4 years and had proportionately worse preoperative health status. No statistically significant differences in postoperative complications were detected. Reoperation rate was 7.9% and 8.6% in the shunt and fenestration groups, respectively. Common reasons for reoperation were shunt revision or replacement and shunt placement after fenestration. Patients requiring shunting after a failed fenestration tended to be younger with higher American Society of Anesthesiologists (ASA) classification. Discussion: Fenestrations are performed more often than shunting. Generally, children who receive shunts are younger than those who undergo fenestration. Acute surgical risk appears to be similar for both operations.

Résultats de l’arthroplastie de la tête radiale implantée en press-fit après fracture complexe de la tête radiale

IntroductionPress-fit radial head arthroplasty (RHA) is increasingly popular in treating complex radial head fractures. This study assessed the outcome of RHA, including the outcome following re-operation, and explored potentially influencing factors. HypothesisComplex radial head fractures treated with press-fit radial head prosthesis would have a favorable outcome. Material and methodsData on all consecutive patients treated with anatomic press-fit RHA from February 2002 to February 2015 were analyzed. Post-surgery clinical and x-rays assessments included a post-discharge evaluation of function. Standardized methods implemented include the assessment of range of motion (ROM), the Mayo Elbow Performance Score (MEPS) and subjective satisfaction scales. ResultsForty-five patients were recruited and 71 % were classified in Mason IV and 62.2 % had the “terrible triad”. Re-operation was performed in 26.7 % and prosthesis removal in 15.6 %. Mean follow-up was 140.8 months (95 % CI 117.7-164) and prosthesis survival was 69.5 % at 24 months. Mean MEPS before re-operations was 86.3±15.9. Pain and/or instability were the most common reasons for re-operation, and re-operations were significantly more frequent in patients having one or more “associated injuries” (p=0.05), but not the terrible triad; and in patients with radiological ‘loosening’ signs (p<0.01). Subjective scores were relatively good in most patients, although the functionality perceived in the re-operation with implant removal group was rather low. DiscussionSeveral studies of complex radial head fractures treated with press-fit radial head prosthesis have also shown favorable results, but the patients in such studies generally had less severe lesions. Moreover, differently from previous reports, this study with a long follow-up has included a younger population with high functionality requirements. Pain and/or instability, as observed in several previous reports, were the most common reasons for re-operation, but contrary to the expectation, the terrible triad was not associated with unfavorable outcome. ConclusionTreatment of complex fractures with press-fit radial head prosthesis, including re-operation with implant removal yields satisfactory results. Most scores of functional and subjective outcome improved following the re-intervention and most patients returned to their usual occupation. Level of evidenceLevel IV; Case Series; Treatment Study.

Long-Term Functional Outcomes Following Septal Extension Grafting in Open Rhinoplasty

BACKGROUND: Septal extension grafts in rhinoplasty can successfully support tip projection/position, tension the lower lateral cartilages, and thereby open the nasal airway. Since long cartilage grafts under tension may warp or collapse over time, long-term outcomes must be evaluated in these patients. We aimed to assess long-term functional outcomes in a large series of patients who underwent septal extension grafting. METHODS: Retrospective chart review was performed on all patients who underwent an open rhinoplasty approach that included use of a septal extension graft performed by a single surgeon from February 2013 through December 2018. Patients with a minimum 12-month postoperative follow-up were included. Pre- and postoperative functional outcomes including history of nasal obstruction, snoring, sleep apnea, sinus congestion, and sinus headaches were recorded. Patient demographics, types of grafts used, patient complaints, readmission, and reoperation rates were recorded. Statistical analysis was performed using McNemar’s test. RESULTS: Of the 385 patients who underwent open rhinoplasty with septal extension grafting during the study period, 127 with adequate follow-up were included; 72% females, 28% males, mean age 28 (range: 5–72) years. 83.5% primary rhinoplasty, 16.5% secondary rhinoplasty. Mean follow-up was 24.2 (range: 11.2–74.0) months. 10.2% had history of cleft lip, 49.6% had history of nasal trauma. Other graft types used included tip/infratip (92.9%), dorsal onlay (90.6%), spreader graft/flap (92.1%), and columellar strut/onlay (7.9%). 85.0% underwent a turbinate outfracture/coblation. Patients reported an improvement in (pre- versus postoperative) nasal airway obstruction (89.8% versus 11.8%; P < 0.001), snoring (55.1% versus 1.6%; P < 0.001), sleep apnea (5.5% versus 0.0%; P = 0.016), sinus congestion (45.7% versus 15.7%; P < 0.001), and sinus headaches (6.3% versus 0.0%; P = 0.008). All patients reported an improvement in aesthetic appearance, with 7.9% undergoing touch-up procedures such as filler or fat injection to smooth a minor contour deformity. 6.5% of patients in this cohort required reoperation; the most common reasons for reoperation were for nasal deformity/deviation (72.0%), persistent airway obstruction (20.0%), and scar revision/dermabrasion (8.0%). Only 3.1% of noncleft, nontrauma patients required revision. No patients reported worsening of nasal airway patency. CONCLUSIONS: Septal extension grafts, when applied in open rhinoplasty patients, can reliably and significantly improve functional outcomes in addition to the aesthetic benefits to tip projection and rotation. Quantitative analysis of nasal airway changes following septal extension grafting will be presented.

Wagner Cone Midterm Survivorship and Outcomes

BackgroundTotal hip arthroplasty (THA) in patients with abnormal proximal femoral anatomy requires an individualized treatment approach to prevent complications. Metaphyseal engaging stems in this population risk fracture, size/offset mismatch, and aseptic loosening. The Wagner conical femoral implant is a short diaphyseal engaging femoral stem that could improve treatment success in this difficult patient population. MethodsWe identified 302 consecutive patients undergoing THA using the Wagner cone femoral prosthesis between January 2010 and January 2017. Clinical, radiographic, and patient-reported outcomes were obtained through chart review and radiographic measurements of postoperative X-rays. We used multivariate analysis to determine predictors of poor outcomes. Kaplan-Meier curves were created to demonstrate implant survivorship with reoperation and revision as endpoints. The average follow-up was 3.2 years, with a minimum of 2 years. ResultsThe implant retention survival rate during the 3.2-year study period was 98.7%. The overall reoperation rate was 4.2%, with infection followed by fracture being the most common reasons for reoperation. No patients were revised for aseptic loosening, and no patients were revised for subsidence. The average subsidence was 1.1 mm. The Harris Hip Score improved from 48.6 ± 7.3 (range, 28-64) preoperatively to 86.1 ± 8.5 (range, 66-100) at latest follow-up. The patient-reported satisfaction rate was 98.3%. ConclusionThe Wagner cone femoral prosthesis demonstrated excellent clinical, radiographic, and patient-reported functional outcomes at midterm follow-up. We recommend use of the Wagner cone in THA patients with challenging proximal femoral anatomy, small femoral diameter, or poor metaphyseal bone quality.

Long-Term Assessment of a Prospective Cohort of Patients Undergoing Laparoscopic Sacrocolpopexy.

To report long-term outcomes after laparoscopic sacrocolpopexy. We conducted a prospective descriptive cohort study on 331 consecutive patients who underwent laparoscopic sacrocolpopexy for symptomatic prolapse (Pelvic Organ Prolapse Quantification [POP-Q] system stage 2 or greater) at one center, with minimum 1.5 years of follow-up by April 30, 2014. Primary outcome measures were Patient Global Impression of Change score and failure at the apex (C≥-1 cm; POP-Q stage 2 or greater). Secondary outcomes were anatomical failure in other compartments, duration of follow-up, occurrence and time point of complications, reinterventions, and functional outcomes by response to a standardized 24-question interview on prolapse and bladder, bowel, and sexual function. Assessment was by an experienced clinician not involved in patient management. The follow-up rate was 84.6% (280/331); 185 of 331 (55.9%) patients were both physically examined and interviewed, and 95 of 331 (25.7%) were interviewed only. The median age at interview was 72 years (interquartile range 13 years), with a follow-up period of 85.5 months (interquartile range 46 months). Approximately 83% (231/280) reported improvement; 5.7% (16/280) were unchanged, 5.7% (16/280) felt slightly worse, and 6.8% (17/280) reported clear deterioration. Anatomical failure at point-C was 8.6% (16/185); anterior (22.2%, 41/185) and posterior (28.6%, 53/185) prolapse were more common than apical prolapse. Of those with level-I anatomical cure, 10.1% (17/185) felt worse; half of them (9/17) because of prolapse in another compartment. The others had urinary problems (41.2%, 7/17), obstructive defecation (11.8%, 2/17), or dyspareunia (11.8%, 2/17). Conversely, the majority of patients with recurrence at the vault (62.5%, 10/16) self-reported to be improved. The reoperation rate was 17.8% (48/270), including 19 (7.0%) for graft-related complications and nine (3.3%) for prolapse. More than four out of five patients (82.5%) felt improved 86 months after laparoscopic sacrocolpopexy. Of those not improved, two thirds had recurrent prolapse; however, typically mid-vaginal. The other third reported urinary or bowel problems or dyspareunia. Reintervention for prolapse was 3.3%. The most common reasons for reoperation were graft-related complications (7.0%) and urinary incontinence (6.7%).

Primary reverse shoulder arthroplasty using contemporary implants is associated with very low reoperation rates

The early results of reverse shoulder arthroplasty (RSA) were influenced to some extent by the use of first-generation implants and surgeons' learning curves, resulting in relatively high reoperation rates. The purpose of this study was to quantify the burden of and identify the indications for reoperation after primary RSA using contemporary implants and techniques. A retrospective review of 1649 primary RSAs implanted consecutively between 2009 and 2015 at a single institution was conducted. All arthroplasties were performed by 5 fellowship-trained shoulder surgeons at a tertiary referral center. Demographic characteristics, indications for primary RSA, and reoperations were analyzed and categorized for trends associated with each type of reoperation performed. A total of 39 reoperations (2.37%) were performed for a variety of indications. Overall, only a few patients with infection or instability required reoperation (0.55%). The most common indications for reoperation were related to the humeral component (1.03%); the majority of humeral component complications were related to a specific design flaw of 1 implant system. RSAs performed for proximal humeral fracture sequelae more commonly underwent reoperation owing to instability or humeral component-related issues; all 4 cases of aseptic humeral stem loosening occurred in the setting of proximal humeral fracture sequela treatment. Only 0.36% of all primary RSAs required reoperation because of glenoid complications. Primary RSA performed with contemporary implants and surgical techniques seems to be associated with a very low rate of reoperation. The most common reasons for reoperation were humeral component fracture for 1 particular implant, humeral loosening, dislocation, infection, and glenoid failure, each occurring at a rate under 1%.

Muscle-Splitting Augmentation-Mastopexy: Implant Protection With an Inferior Dermoglandular Flap.

Simultaneous augmentation-mastopexy can achieve excellent patient and surgeon satisfaction but continues to pose a challenge, with revision rates of up to 25%. Recurrent ptosis and poor overall breast shape are 2 common reasons for reoperation, whereas some of the most feared complications is breast implant exposure, infection, and loss secondary to wound breakdown; excessively large implants or too much tension during closure are possible contributing factors. We describe a technique for augmentation-mastopexy combining a muscle-splitting pocket for implant placement along with an inferior flap, which helps secure the implant in place and provides coverage in case of wound dehiscence. A retrospective chart review was performed (January 2015 to December 2017) of women who underwent augmentation-mastopexy with round, textured silicone gel implants using a muscle-splitting technique combined with an inferior de-epithelialized dermoglandular flap. A total of 118 patients (236 breasts) were operated on. Mean follow-up was 13 months (10-42 months). Mean patient age was 33.3 years (24-55 years). Mean operative time was 102.9 minutes (80-135 minutes), and implant size ranged from 175 to 350 mL (mode, 275 mL). There were no cases of implant extrusion, nipple-areola complex ischemia, or surgical site infection; however, 1 patient required revision surgery for implant malposition, and 2 had a postoperative hematoma. In summary, the technique we describe combines 2 established mammaplasty techniques, ensuring upper pole fullness with good cleavage, implant protection in case of wound breakdown, and good patient satisfaction as evidenced by a low revision rate and minimal complications. LEVEL OF EVIDENCE: IV, therapeutic. Evidence obtained from multiple time series with or without the intervention, such as case studies.

Reoperation Rate After Primary Augmentation With Smooth, Textured, High Fill, Cohesive, Round Breast Implants (RANBI-I Study).

BackgroundReoperation after primary breast augmentation remains an important clinical issue.ObjectiveThe authors sought to evaluate incidence and causes of reoperation in patients who underwent primary augmentation.MethodsThis retrospective, noninterventional study conducted at 16 Canadian sites reviewed medical records and patient-completed questionnaires of women who underwent primary breast augmentation with smooth or textured Natrelle Inspira implants containing TruForm 1 or TruForm 2 gel. Patients were aged ≥22 years, received implants via inframammary fold incision, and returned for follow-up at 2 to 4 years.ResultsA total of 319 women received Inspira implants (smooth TruForm 2, n = 205; textured TruForm 2, n = 99; smooth or textured TruForm 1, n = 15). At follow-up, 30 women (9.4%) had undergone reoperation, including 19 (9.3%) in the smooth TruForm 2 subgroup and 9 (9.1%) in the textured TruForm 2 subgroup. The mean time to reoperation was 1.2 years; the risk rate for reoperation was 9.9% at 3 years. The most common reasons for reoperation were implant malposition (36.7%), capsular contracture (33.3%), and the patient’s request for a change in implant size or style (20.0%). Most women were very or somewhat satisfied with the initial surgery (89.3% overall; 90.7% smooth TruForm 2; 86.9% textured TruForm 2). Thirty-four women (10.7%) reported adverse events, including 20 (9.8%) in the smooth TruForm 2 subgroup and 14 (14.1%) in the textured TruForm 2 subgroup.ConclusionsThis analysis suggests that Natrelle Inspira TruForm 2 implants are safe when used in primary breast augmentation, resulting in low reoperation rates that are consistent with those for other breast implants.Level of Evidence: 4

National Surgical Quality Improvement Program analysis of unplanned reoperation in patients undergoing low anterior resection or abdominoperineal resection for rectal cancer

BackgroundThe rate of unplanned reoperation for rectal cancer can provide information about surgical quality. We sought to determine factors associated with unplanned reoperation after low anterior resection and abdominoperineal resection for patients with rectal cancer and outcomes after these reoperations. MethodsThe American College of Surgeons National Surgical Quality Improvement Program database was used to conduct this retrospective study. Patients who underwent elective low anterior resection and abdominoperineal resection for rectal cancer from 2012–2014 were identified. The primary outcomes were 30-day reoperation rates and postoperative complications. ResultsA total of 454 low anterior resection patients (5.9%) and 289 abdominoperineal resection patients (8.1%) required reoperation within 30 days of their index operation. The most common reasons for reoperation were infection, bleeding, and bowel obstruction. Multivariate analysis revealed that male sex (odds ratio: 1.5, P = .001), poor functional status (odds ratio: 2.2, P = .04), operative time (odds ratio: 1.001, P = .01), low preoperative albumin (odds ratio: 0.79, P = .04), and lack of ostomy (odds ratio, 0.66, P = .005) were independent risk factors for reoperation after low anterior resection. Smoking (odds ratio: 1.7, P = .001), chronic obstructive pulmonary disease (odds ratio: 1.8, P = .03), poor functional status (odds ratio: 2.1, P = .032), operative time (odds ratio: 1.003, P < .001), low preoperative albumin (odds ratio: 0.69, P = .007), and open approach (odds ratio: 1.5, P = .02) were independent risk factors for reoperation after abdominoperineal resection. Postoperative complication rates are high for those undergoing reoperation, often leading to non-home discharge (P < .001) after reoperation. ConclusionReoperation after low anterior resection and abdominoperineal resection for rectal cancer is not uncommon. This study highlights the indications for reoperation, potentially modifiable preoperative risk factors for reoperation, and the morbidity associated with such operations.

Acute Surgical Risk Profile of Intramedullary Spinal Cord Tumor Resection in Pediatric Patients: A Pediatric National Surgical Quality Improvement Program Analysis

The purpose of the present study was to characterize the acute (30-day) surgical risk profile of pediatric patients undergoing surgical resection of intramedullary spinal cord tumors (IMSCTs). Preoperative factors were collected from the Pediatric American College of Surgeons National Surgical Quality Improvement Program database for patients identified by Current Procedural Terminology codes for laminectomy and International Classification of Diseases codes for IMSCTs from 2012 to 2016. The postoperative outcomes were compared by tumor location and type. The mean age of the 139 patients meeting all inclusion criteria was 8.7 years, with a male predominance (58.7%). The cervical and thoracic IMSCT populations had worst preoperative health status, as indicated by American Society of Anesthesiologists class, and a greater proportion of malignant tumors compared with the lumbar IMSCT population. No patient died; 8.6% of the patients were readmitted, and 6.5% required reoperation. Of the 12 readmissions, 8 were required for patients with malignant tumors. The patients with cervical IMSCTs returned to the operating room at a significantly greater rate than did the thoracic and lumbar IMSCT populations. Two common reasons for reoperation in the cervical population were issues related to respiration and hydrocephalus management. The complications included 13 cases of infection, 6 of urinary tract infection, and 5 cases of surgical site infection. Resection of IMSCTs in the pediatric population is a relatively low-risk procedure in terms of acute surgical complications. However, surgeons operating in the cervical spine should be aware of the increased risk of reoperation, in particular as it pertains to respiratory issues and hydrocephalus.

Thirty-Day Outcomes After Craniotomy for Primary Malignant Brain Tumors: A National Surgical Quality Improvement Program Analysis.

Despite improved perioperative management, the rate of postoperative morbidity and mortality after brain tumor resection remains considerably high. To assess the rates, causes, timing, and predictors of major complication, extended length of stay (>10 d), reoperation, readmission, and death within 30 d after craniotomy for primary malignant brain tumors. Patients were extracted from the National Surgical Quality Improvement Program registry (2005-2015) and analyzed using multivariable logistic regression. A total of 7376 patients were identified, of which 948 (12.9%) experienced a major complication. The most common major complications were reoperation (5.1%), venous thromboembolism (3.5%), and death (2.6%). Furthermore, 15.6% stayed longer than 10 d, and 11.5% were readmitted within 30 d after surgery. The most common reasons for reoperation and readmission were intracranial hemorrhage (18.5%) and wound-related complications (11.9%), respectively. Multivariable analysis identified older age, higher body mass index, higher American Society of Anesthesiologists (ASA) classification, dependent functional status, elevated preoperative white blood cell count (white blood cell count [WBC], >12 000 cells/mm3), and longer operative time as predictors of major complication (all P<.001). Higher ASA classification, dependent functional status, elevated WBC, and ventilator dependence were predictors of extended length of stay (all P<.001). Higher ASA classification and elevated WBC were predictors of reoperation (both P<.001). Higher ASA classification and dependent functional status were predictors of readmission (both P<.001). Older age, higher ASA classification, and dependent functional status were predictors of death (all P<.001). This study provides a descriptive analysis and identifies predictors for short-term complications, including death, after craniotomy for primary malignant brain tumors.

A nationwide analysis of re-exploration after liver transplant

BackgroundA retrospective review to investigate rate and outcomes of re-exploration following liver transplantation in the United States. MethodsThe NIS database was used to examine outcomes of patients who underwent re-exploration following liver transplantation from 2002 to 2012. Multivariate regression analysis was performed to compare outcomes of patients with and without reoperation. ResultsWe sampled a total of 12,075 patients who underwent liver transplantation. Of these, 1505 (12.5%) had re-exploration during the same hospitalization. Hemorrhagic (67.9%) and biliary tract anastomosis complication (14.8%) were the most common reasons for reoperation. Patients with reoperation had a significantly higher mortality than those who did not (11.6% vs. 3.8%, AOR: 3.01, P < 0.01). Preoperative coagulopathy (AOR: 1.71, P < 0.01) and renal failure (AOR: 1.57, P < 0.01) were associated with hemorrhagic complications. Peripheral vascular disorders (AOR: 2.15, P < 0.01) and coagulopathy (AOR: 1.32, P < 0.01) were significantly associated with vascular complications. Risk of wound disruption was significantly higher in patients with chronic pulmonary disease (AOR: 1.50, P < 0.01). ConclusionRe-exploration after liver transplantation is relatively common (12.5%), with hemorrhagic complication as the most common reason for reoperation. Preoperative coagulation disorders significantly increase hemorrhagic and vascular complications. Further clinical trails should investigate prophylactic strategies in high risk patients to prevent unplanned reoperation.
