Long-term survivorship and results in lower limb arthroplasty: a registry-based comparison study.

INTRODUCTION: Popularity of joint replacement surgery due to ever aging population surges the demand for a proper national joint registry. Our Chinese University of Hong Kong - Prince of Wales Hospital (CUHK-PWH) joint registry has passed the 30th year. The aims of this study are 1) summarize our territory-wide joint registry which has passed the 30th year since establishment and 2) compare our statistics with other major joint registries. METHODS: Part 1 was to review the CUHK-PWH registry. Demographic characteristics of our patients who underwent knee and hip replacements had been summarized. Part 2 was a series of comparisons with registries from Sweden, UK, Australia and New Zealand. RESULTS: CUHK-PWH registry captured 2889 primary total knee replacements (TKR) (110 (3.81%) revision) and 879 primary total hip replacements (THR) (107 (12.17%) revision). Median Surgery time of TKR was shorter than THR. Clinical outcome scores were much improved after surgery in both. Uncemented of hybrid in TKR were most popular in Australia (33.4%) and 40% in Sweden and UK. More than half of TKR and THR patients showed the highest percentage with ASA grade 2. New Zealand reflected the best cumulative percentage survival 20 years after surgery of 92.2%, 76.0%, 84.2% survivorship 20 years after TKR, unicompartmental knee replacement (UKR) and Hip. CONCLUSION: A worldwide accepted patient-reported outcome measure (PROM) is recommended to develop to make comparisons among registries and studies feasible. Completeness of registry data is important and useful to improve surgical performance through data comparisons from different regions. Funding from government on sustaining registries is reflected. Registries from Asian countries have yet to be grown and reported.

Impact of Coronavirus Disease-2019 Protocols on Primary and Revision Total Knee Arthroplasty.

Background: Surgical site infection (SSI) after total knee arthroplasty (TKA) is associated with increased morbidity and healthcare expenditures. During the coronavirus disease-2019 (COVID-19) pandemic, our institution intensified hygiene standards, including greater glove, personal protective equipment (PPE), and mask use. We assessed the effect of these changes on SSI rates in primary total knee arthroplasty (pTKA) and revision total knee arthroplasty (rTKA). Patients and Methods: A retrospective review was performed identifying TKA from January 2019 to June 2021 at a single institution. Baseline characteristics and outcomes were compared before (January 2019 to February 2020) and during (May 2020 to June 2021) the COVID-19 pandemic when no restriction on operative services was in place and were further analyzed during the first (May 2020 to November 2020) and second (December 2020 to June 2021) periods after full operative services were restored. Results: A total of 3,398 pTKA (pre-pandemic: 1,943 [57.2%]; pandemic: 1,455 [42.8%]) and 454 rTKA (pre-pandemic: 229 [50.4%]; pandemic: 225 [49.6%]) were included. For primary cases, superficial and deep SSI rates were similar before and during COVID-19; however, for revision TKA, the incidence of all (-0.32%, p = 0.035) and superficial (-0.32%, p = 0.035) SSIs decreased during COVID-19. Primary TKA had longer operative times (p < 0.001) and shorter length of stay (LOS; p < 0.001) during COVID-19. Both pTKA (p < 0.001) and rTKA (p = 0.003) were discharged to skilled nursing facilities less frequently during COVID-19 as well. Conclusions: After our hospital implemented COVID-19-motivated hygienic protocols, superficial SSI rates decreased in rTKA but not in pTKA. During COVID-19, patients were less likely to be discharged to skilled nursing facilities, and pTKA operative times increased. Although these changes occurred during intensified hygiene protocols, further research is needed to determine how these factors contributed to the observed changes.

Can revision of RYGB to sleeve gastrectomy be a solution to inadequate weight loss treatment?

We aimed to discuss the weight loss success of the revision of RYGB to sleeve gastrectomy (SG). Between January 2019 and June 2020, four patients' files were analyzed retrospectively. Post-RYGB mean minimal BMI was 27.4 ± 9.47 kg/m², before SG the mean BMI was 43.41 ± 4.16 kg/m2. Post-operative gastric fistula developed in two patients. The mean follow-up time after revision surgery was 17.25 ± 6.89 months, mean excess weight loss (EWL) was 74.77 ± 8.94%, and mean BMI was 32.65 ± 2.9 kg/m2. Despite high rate of major complications, revision of RYGB to SG is successful in weight loss and resolving certain complications of RYGB.

Nuestro objetivo era discutir el éxito en la pérdida de peso de la revisión de BGYR a gastrectomía en manga (SG). Entre enero de 2019 y junio de 2020, se analizaron retrospectivamente los archivos de cuatro pacientes. El IMC mínimo medio post BGYR fue 27.4 ± 9.47 kg/m², antes de SG el IMC medio fue 43.41 ± 4.16 kg/m2. En dos pacientes se desarrolló una fístula gástrica posoperatoria. El tiempo medio de seguimiento después de la cirugía de revisión fue de 17.25 ± 6.89 meses, la pérdida media de exceso de peso (PEP) fue de 74.77 ± 8.94% y el IMC medio fue de 32.65 ± 2.9 kg/m2. A pesar de la alta tasa de complicaciones mayores, la revisión de BGYR a SG tiene éxito en la pérdida de peso y la resolución de ciertas complicaciones de BGYR.

No exponential rise in revision knee replacement surgery over the past 15 years: an analysis from the National Joint Registry.

OBJECTIVE: To investigate trends in the incidence rate and the main indication for revision knee replacement (rKR) over the past 15 years in the UK. METHOD: Repeated national cross-sectional study from 2006 to 2020 using data from the National Joint Registry (NJR). Crude incidence rates were calculated using population statistics from the Office for National Statistics. RESULTS: Annual total counts of rKR increased from 2,743 procedures in 2006 to 6,819 procedures in 2019 (149% increase). The incidence rate of rKR increased from 6.3 per 100,000 adults in 2006 (95% CI 6.1 to 6.5) to 14 per 100,000 adults in 2019 (95% CI 14 to 14) (122% increase). Annual increases in the incidence rate of rKR became smaller over the study period. There was a 43.6% reduction in total rKR procedures in 2020 (during the Covid-19 pandemic) compared to 2019. Aseptic loosening was the most frequent indication for rKR overall (20.7% procedures). rKR for aseptic loosening peaked in 2012 and subsequently decreased. rKR for infection increased incrementally over the study period to become the most frequent indication in 2019 (2.7 per 100,000 adults [95% CI 2.6 to 2.9]). Infection accounted for 17.1% first linked rKR, 36.5% second linked rKR and 49.4% third or more linked rKR from 2014 to 2019. CONCLUSIONS: Recent trends suggest slowing of the rate of increase in the incidence of rKR. Infection is now the most common indication for rKR, following recent decreases in rKR for aseptic loosening. Infection was prevalent in re-revision KR procedures.

Sars-Cov-2 infection as a possible risk factor for prosthesis endocarditis: A challenging redo-Bentall for subvalvular abscess.

BACKGROUND: Candida Parapsilosis is an unusual agent of prosthetic endocarditis in immunocompetent individuals but Coronavirus disease 2019 is reported to be associated with a transient immunodeficency that exposes patientes to opportunistic infections. CASE REPORT: We describe a dreadful case of Candida Parapsilosis endocarditis in a transient immunosuppressed patient recently infected with severe acute respiratory syndrome-Coronavirus 2019. CONCLUSION: Considering that the symptoms of Candida Parapsilosis infection and the symptoms of Coronavirus disease-2019 may overlap, it is important never to understimate the non-specific symptoms to improve patient outcome, especially in patient with previous Coronavirurs disease-2019 infection and with prosthetic material grafting.

Characterizing the volume of surgery and post-operative complications during the COVID-19 pandemic.

PURPOSE: The COVID-19 pandemic led to unprecedented changes in volume and quality of surgery. Utilizing the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database, the current study assesses the impact of COVID-19 on surgical volume during each quarter of 2020 in comparison to 2019. Quality of surgical care during 2020 was also investigated by assessing postoperative complications, readmissions, and reoperations during 2020 in comparison to the previous 5 years. MATERIALS AND METHODS: The NSQIP database was queried from 2015 to 2020. Descriptive statistics and a chi-squared test were utilized to compare demographic variables. A seasonal autoregressive integrated moving average time-series model was fit to assess the trend and seasonality of complications from 2015 to 2019 and was used to forecast the proportion of complications in the year 2020 and compared the forecast with the actual proportions graphically. RESULTS: There were fewer patients operated on in 2020 compared to 2019, with the most dramatic drop in Q2 with a nearly 27% decrease. Patients with ASA class 3 or greater were operated on at a greater proportion in every quarter of 2020. Q2 of 2020 represented the highest proportion of any operative complications since 2015 at ~13%. Q4 of 2020 demonstrated a return to 2020 Q1 complication proportions. CONCLUSION: Surgical volume was heavily affected in 2020, particularly in Q2. Patients during Q2 of 2020 were generally of a higher ASA class and had increased operative complications. Operative volume and overall surgical complication rate normalized over the next two quarters.

Impact of the COVID-19 Pandemic on Metabolic and Bariatric Surgery Utilization and Safety in the United States.

BACKGROUND: Metabolic and bariatric surgery (MBS) is a safe and effective treatment option for severe obesity. The utilization and health and safety outcomes of MBS in the United States (US) during the COVID-19 pandemic versus 2015-2019 among adolescent and adult populations and by ethnic group is largely unknown. METHODS: The 2015-2020 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) longitudinal (30-day) cohort data was used to compare adolescent and adult (N = 1,134,522) post-operative outcomes and to calculate MBS utilization pre-pandemic (2015-2019) versus pandemic (2020). Cochran-Armitage trend tests compared MBS utilization and safety outcomes over time from 2015 to 2020. Logistic regression analysis compared the odds of hospital readmission and MBS completion pre-pandemic versus pandemic by key characteristics. RESULTS: MBS utilization increased by 8.1% among youth (from 970 to 1140 procedures) and decreased by 10.2% among adults (from 205,232 to 167,384) from 2019 to 2020, respectively. MBS increased by 18.5% during the pandemic for youth who identified as other/multiracial (P trend < 0.001). Among US youth, the number of reoperations and reinterventions significantly decreased over the 6-year time frame (P trend < .001). Among US adults, 30-day post MBS mortality, reoperations, readmissions, and reinterventions all showed a significant decrease over time (P trend < .001) while septic shock and sepsis increased from pre-pandemic to the first year of the pandemic (P trend < 0.001). CONCLUSION: In comparison to 2019 (or to previous years), US MBS utilization increased for youth but decreased for adults during the first year of the COVID-19 pandemic. Safety outcomes were comparable to those of the pre-pandemic years.

Impact of COVID-19 Protocols on Primary and Revision Total Hip Arthroplasty.

BACKGROUND: Surgical site infection (SSI) after total hip arthroplasty (THA) is associated with increased morbidity, mortality, and healthcare expenditures. Our institution intensified hygiene standards during the COVID-19 pandemic; hospital staff exercised greater hand hygiene, glove use, and mask compliance. We examined the effect of these factors on SSI rates for primary THA (pTHA) and revision THA (rTHA). METHODS: A retrospective review was performed identifying THA from January 2019 to June 2021 at a single institution. Baseline characteristics and outcomes were compared before (January 2019 to February 2020) and during (May 2020 to June 2021) the COVID-19 pandemic and during the first (May 2020 to November 2020) and second (December 2020 to June 2021) periods of the pandemic. Cohorts were compared using the Chi-squared test and independent samples t-test. RESULTS: A total of 2,682 pTHA (prepandemic: 1,549 [57.8%]; pandemic: 1,133 [42.2%]) and 402 rTHA (prepandemic: 216 [53.7%]; Pandemic: 186 [46.2%]) were included. For primary and revision cases, superficial and deep SSI rates were similar before and during COVID-19. During COVID-19, the incidence of all (-0.43%, P = .029) and deep (-0.36%, P = .049) SSIs decreased between the first and second periods for rTHA. pTHA patients had longer operative times (P < .001) and shorter length of stay (P = .006) during COVID-19. Revision cases had longer operative times (P = .004) and length of stay (P = .046). Both pTHA and rTHA were discharged to skilled nursing facilities less frequently during COVID-19. CONCLUSION: During COVID-19, operative times were longer in both pTHA and rTHA and patients were less likely to be discharged to a skilled nursing facility. Although intensified hygienic standards may lower SSI rates, infection rates did not significantly differ after our hospital implemented personal protective guidelines and a mask mandate.

Reoperation of Maisonneuve fracture with quadricortical syndesmotic screw, zip tight and fibula elongation by autograph: a case report in covid-19 patient.

PURPOSE: . We report a Maisonneuve case of reoperation with proximal fibula fracture, diastasis of syndesmosis and parcel posterior detachment of the third malleolus. PRESENTATION OF CASES: We report a case of 49- year old patient with a Maisonneuve fracture. The first surgery has failed with three-cortical screw rupture.  The second surgery was based on the implantation of quadricortical screw, zip tight and fibula elongation with autograph. The results were excellent despite the patient having contracted Covid-19 virus during rehabilitation. DISCUSSION: Maisonneuve fracture is a misdiagnosed fracture. The diagnosis may be made by RX or TC of lower limb. There are many treatments provides to stabilized and reduced the ankle. We believe the gold standard is the correct realignment of syndesmosis and a strong synthesis. CONCLUSION: The Maisonneuve fracture accounts for 7% of all ankle fractures but misdiagnosed. We emphasize the importance of making good diagnosis of this fracture for an excellent surgical result and avoiding the chronic complications of incorrect treatment. In this case the physical rehabilitation is delayed by covid-19 infection so we suggest to carry out studies on post-operative period in orthopedic patients during this global pandemic.

The impact of the COVID-19 pandemic on alloplastic breast reconstruction: An analysis of national outcomes.

BACKGROUND: Immediate alloplastic breast reconstruction shifted to the outpatient setting during the COVID-19 pandemic to conserve inpatient hospital beds while providing timely oncologic care. We examine the National Surgical Quality Improvement Program (NSQIP) database for trends in and safety of outpatient breast reconstruction during the pandemic. METHODS: NSQIP data were filtered for immediate alloplastic breast reconstructions between April and December of 2019 (before-COVID) and 2020 (during-COVID); the proportion of outpatient procedures was compared. Thirty-day complications were compared for noninferiority between propensity-matched outpatients and inpatients utilizing a 1% risk difference margin. RESULTS: During COVID, immediate alloplastic breast reconstruction cases decreased (4083 vs. 4677) and were more frequently outpatient (31% vs. 10%, p < 0.001). Outpatients had lower rates of smoking (6.8% vs. 8.4%, p = 0.03) and obesity (26% vs. 33%, p < 0.001). Surgical complication rates of outpatient procedures were noninferior to propensity-matched inpatients (5.0% vs. 5.5%, p = 0.03 noninferiority). Reoperation rates were lower in propensity-matched outpatients (5.2% vs. 8.0%, p = 0.003). CONCLUSION: Immediate alloplastic breast reconstruction shifted towards outpatient procedures during the COVID-19 pandemic with noninferior complication rates. Therefore, a paradigm shift towards outpatient reconstruction for certain patients may be safe. However, decreased reoperations in outpatients may represent undiagnosed complications and warrant further investigation.

Comparison of Operating Room Air Quality in Primary Versus Revision Total Knee Arthroplasty.

BACKGROUND: Airborne biologic particles (ABPs) can be measured intraoperatively to evaluate operating room (OR) sterility. Particulate matter (PM) up to 2.5 microns can contain microbial species which may increase infection risk. Our study examines the differences in air quality and ABP count in primary total knee arthroplasty (TKA) and revision TKA (rTKA). METHODS: We analyzed primary and rTKAs in a single OR at an academic institution from January 2020 to December 2020. Procedures from March 15, 2020, to May 4, 2020, were excluded to avoid COVID-related confounding. Temperature, humidity, and ABP count per minute were recorded with a particle counter intraoperatively and cross-referenced with surgical data from the electronic health records using procedure start and end times. Descriptive statistics were used to evaluate the differences in variables. P values were calculated using t-test and chi-square test. RESULTS: A total of 107 TKA cases were included: 79 (73.8%) primary TKAs and 28 (26.2%) rTKAs. Time spent in an OR was significantly higher for rTKAs (primary: 176 ± 46.7 minutes vs revision: 220 ± 47.1 minutes, P < .0001). Compared to primary TKAs, rTKAs had significant percent increases in ABP rates for particles measuring 0.3 µm (+70.4%, P < .001), 0.5 µm (+97.2%, P < .0001), 1.0 µm (+53.2%, P = .001), and 2.5 µm (+30.3%, P = .017) and for PM 2.5 (+108.3%, P < .001) and PM 5.0 (+105.6%, P < .001). CONCLUSION: rTKAs had significantly longer time spent in an OR and significant percent increases in ABP rates for particles measuring 0.3 µm, 0.5 µm, and 1.0 µm compared to primary TKAs. Measurements of PM 2.5 and 5.0 (which can contain large numbers of microbes) were also significantly greater in rTKAs. Further research is needed to determine whether the size and quantity of ABPs translate to higher infection rates after rTKA.

UK poSt Arthroplasty Follow-up rEcommendations (UK SAFE): what does analysis of linked, routinely collected national data sets tell us about mid-late term revision risk after hip replacement? Retrospective cohort study.

OBJECTIVE: To identify patients at risk of mid-late term revision of hip replacement to inform targeted follow-up. DESIGN: Analysis of linked national data sets from primary and secondary care (Clinical Practice Research Datalink (CPRD-GOLD); National Joint Registry (NJR); English Hospital Episode Statistics (HES); Patient-Reported Outcome Measures (PROMs)). PARTICIPANTS: Primary elective total hip replacement (THR) aged≥18. EVENT OF INTEREST: Revision surgery≥5 years (mid-late term) after primary THR. STATISTICAL METHODS: Cox regression modelling to ascertain risk factors of mid-late term revision. HR and 95% CI assessed association of sociodemographic factors, comorbidities, medication, surgical variables and PROMs with mid-late term revision. RESULTS: NJR-HES-PROMs data were available from 2008 to 2011 on 142 275 THR; mean age 70.0 years and 61.9% female. CPRD GOLD-HES data covered 1995-2011 on 17 047 THR; mean age 68.4 years, 61.8% female. Patients had minimum 5 years postprimary surgery to end 2016. In NJR-HES-PROMS data, there were 3582 (2.5%) revisions, median time-to-revision after primary surgery 1.9 years (range 0.01-8.7), with 598 (0.4%) mid-late term revisions; in CPRD GOLD, 982 (5.8%) revisions, median time-to-revision 5.3 years (range 0-20), with 520 (3.1%) mid-late term revisions.Reduced risk of mid-late term revision was associated with older age at primary surgery (HR: 0.96; 95% CI: 0.95 to 0.96); better 6-month postoperative pain/function scores (HR: 0.35; 95% CI: 0.27 to 0.46); use of ceramic-on-ceramic (HR: 0.73; 95% CI: 0.56 to 0.95) or ceramic-on-polyethylene (HR: 0.76; 95% CI: 0.58 to 1.00) bearing surfaces.Increased risk of mid-late term revision was associated with the use of antidepressants (HR: 1.32; 95% CI: 1.09 to 1.59), glucocorticoid injections (HR: 1.33; 95% CI: 1.06 to 1.67) and femoral head size≥44 mm (HR: 2.56; 95% CI: 1.09 to 6.02)No association of gender, obesity or Index of Multiple Deprivation was observed. CONCLUSION: The risk of mid-late term THR is associated with age at primary surgery, 6-month postoperative pain and function and implant factors. Further work is needed to explore the associations with prescription medications observed in our data.

Patient Perspectives on Defining Textbook Outcomes Following Major Abdominal Surgery.

BACKGROUND: The composite metric textbook outcome (TO) has recently gained interest as a novel quality measure. However, the criteria for defining a TO have not been rigorously defined and patient perspectives on the characteristics of TO are unknown. METHODS: Patients who underwent major abdominal surgery at a single tertiary care center were administered a customized survey designed to ascertain their perspectives on defining TOs. The relationship between patient-reported and clinically defined TO rates was compared. RESULTS: Among 79 patients who underwent gastrointestinal (51%), pancreatic (29%), hepatic (18%), or other major abdominal (3%) operations, 57% were female and 86% had an ASA class ≥3. Most patients underwent surgery for malignancy (87%) with 60% undergoing an open operation. Patients most commonly valued no mortality following surgery (96%), no reoperation (75%), and having a margin negative resection (73%) as "extremely important." In contrast, those outcomes that were most commonly valued as "not important at all" or "minimally important" were receiving a blood transfusion (24%) and not having any complications (13%). Using previously published criteria for TOs, 47 (60%) patients were classified as having a clinically defined TO; in contrast, 68 patients (86%) self-reported their outcome was textbook. Self-reported responses were concordant with clinically defined TO criteria 63% of the time (McNemar's test: S=15.2, p<0.01, evidence of disagreement). CONCLUSION: There was significant discordance between patient-reported versus clinically defined measures of TOs, suggesting patients value other considerations beyond traditional factors when evaluating the success of their surgery. Future studies should delineate these relationships and incorporate these factors to refine TO definitions.

Acute Corneal Transplant Rejection After Severe Acute Respiratory Syndrome Coronavirus 2 mRNA-1273 Vaccination.

PURPOSE: The purpose of this article was to report a case of full-thickness corneal transplant rejection 3 days after immunization with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Moderna mRNA-1273 vaccine. METHODS: Case Report. RESULTS: A 51-year-old man with a history of keratoconus and penetrating keratoplasty underwent repeat penetrating keratoplasty for graft failure. The patient had an uncomplicated intraoperative and postoperative course with improved vision and a healthy graft. The patient received the SARS-CoV-2 Moderna vaccine on postoperative week 3, and within 3 days, the patient began developing eye pain, photophobia, and blurred vision. The patient was found to have graft rejection with corneal edema and endothelial keratic precipitates. The rejection did not improve despite a trial of increased topical steroids and ultimately evolved into graft failure. CONCLUSIONS: To the best of our knowledge, this case of full-thickness graft rejection after the Moderna SARS-CoV-2 mRNA vaccination is the first to be reported worldwide. The temporal relationship between vaccination and subsequent rejection is highly suggestive of causation due to the short interval (3 days) between vaccination and rejection and the lack of other inciting factors in an otherwise healthy graft. Patients with corneal transplants who plan to take the COVID-19 vaccinations should be counseled on symptoms and closely monitored, and an individualized plan should be made in discussion with the ophthalmologist.

The PROCEM study protocol: Added value of preoperative contrast-enhanced mammography in staging of malignant breast lesions - a prospective randomized multicenter study.

BACKGROUND: Correct preoperative estimation of the malignant extent is crucial for optimal planning of breast cancer surgery. The sensitivity of mammography is lower in dense breasts, and additional imaging techniques are sometimes warranted. Contrast-enhanced mammography (CEM) has shown similar sensitivity and in some cases better specificity, than magnetic resonance imaging (MRI) in small, observational studies. CEM may be more cost-effective than MRI, and may provide better identification of the tumor extent, however, no randomized trials have been performed to date to investigate the added value of CEM. In a feasibility study, we found that the treatment was changed in 10/47 (21%) cases after additional CEM. The purpose of the present study is to evaluate the added value of CEM in preoperative staging of breast cancer in a randomized study. METHOD: This prospective randomized study will include 440 patients with strongly suspected or established diagnosis of breast malignancy, based on assessment with mammography, ultrasound and core biopsy/cytology, and for whom primary surgery is planned. Patients will be randomized 1:1 using a web-based randomization tool to additional investigation with CEM or no further imaging. The CEM findings will be taken into consideration, which may lead to changes in primary treatment, which is the primary endpoint of this study. Secondary endpoints include rate of reoperation and number of avoidable mastectomies, as well as a cost-benefit analysis of additional CEM. Patient-reported health-related quality of life will be investigated at 1 year with the validated Breast-Q™ questionnaire. The rate of local recurrence or new cancer ipsi- or contralaterally within 5 years will be assessed from medical records and pathology reports. DISCUSSION: The aim of this trial is to explore the added value of CEM in preoperative staging of breast cancer. The results obtained from this study will contribute to our knowledge on CEM as an additional imaging method to standard investigation with digital mammography and ultrasound. The findings may also provide additional information on which patient groups would benefit from CEM, and on the economic aspects of CEM in standard preoperative practice. TRIAL REGISTRATION: This trial is registered at clinicaltrials.gov , registration no: NCT04437602 , date of registration: June 18, 2020.

Robotic Colostomy Takedown in a Patient with Extensive Ventral Hernias and Adhesive Disease.

STUDY OBJECTIVE: To demonstrate a surgical video wherein a robot-assisted colostomy takedown was performed with anastomosis of the descending colon to the rectum after reduction of ventral hernias and extensive lysis of adhesions. DESIGN: Case report and a step-by-step video demonstration of a robot-assisted colostomy takedown and end-to-side anastomosis. SETTING: Tertiary referral center in New Haven, Connecticut. A 64-year-old female was diagnosed with stage IIIA endometrioid endometrial adenocarcinoma in 2015 when she underwent an optimal cytoreductive surgery. In addition, she required resection of the sigmoid colon and a descending end colostomy with Hartmann's pouch, mainly secondary to extensive diverticulitis. After adjuvant chemoradiation, she remained disease free and desired colostomy reversal. Body mass index at the time was 32 kg/m2. Computed tomography of her abdomen and pelvis did not show any evidence of recurrence but was notable for a large ventral hernia and a parastomal hernia. She then underwent a colonoscopy, which was negative for any pathologic condition, except for some narrowing of the distal rectum above the level of the levator ani. INTERVENTIONS: Enterolysis was extensive and took approximately 2 hours. The splenic flexure of the colon had to be mobilized to provide an adequate proximal limb to the anastomosis site. An anvil was then introduced into the distal descending colon through the colostomy site. A robotic stapler was used to seal the colostomy site and detach it from the anterior abdominal wall. Unfortunately, the 28-mm EEA sizer (Covidien, Dublin, Ireland) perforated through the distal rectum, caudal to the stricture site. A substantial length of the distal rectum had to be sacrificed secondary to the perforation, which mandated further mobilization of the splenic flexure. The rectum was then reapproximated with a 3-0 barbed suture in 2 layers. This provided us with approximately 6- to 8-cm distal rectum. An end-to-side anastomosis of the descending colon to the distal rectum was performed. Anastomotic integrity was confirmed using the bubble test. Because of the lower colorectal anastomosis, a protective diverting loop ileostomy was performed. The patient had an uneventful postoperative course. A hypaque enema performed 3 months after the colostomy takedown showed no evidence of anastomotic leak or stricture. The ileostomy was then reversed without any complications. CONCLUSION: Robot-assisted colostomy takedown and anastomosis of the descending colon to rectum were successfully performed. Although there is a paucity of literature examining this technique within gynecologic surgery, the literature on general surgery has supported laparoscopic Hartmann's reversal and has demonstrated improved rates of postoperative complications and incisional hernia and reduced duration of hospitalization [1]. Minimally invasive technique is a feasible alternative to laparotomy for gynecologic oncology patients who undergo colostomy, as long as the patients are recurrence free.

Posterior tilt in nondisplaced femoral neck fractures increases the risk of reoperations after osteosynthesis. A systematic review and meta-analysis.

OBJECTIVE: To conduct a systematic review on the effect of posterior tilt on reoperations, patient reported outcome measures (PROM) and functional outcome following osteosynthesis of undisplaced FNFs (uFNF). MATERIAL AND METHODS: A search string was developed with the aid of a scientific librarian and the search was performed in PubMed, CINAHL and Embase. The studies were screened independently by two authors using Covidence. Data were extracted by two authors and quality assessment was performed using Robins-I tool. The meta-analyses were performed in STATA IC 16 using Risk Ratio as the primary effect estimate. RESULTS: In total, 617 studies were screened and ten studies were included with a total of 3,131 patients. The mean age ranged from 68.3 to 85.0 years and the prevalence of posterior tilt ≥20° in the studies ranged from 4.5% to 27.6%. There were 10.3% reoperations when posterior tilt was <20° whereas there were 24.5% when posterior tilt was ≥20° The meta-analysis therefore demonstrated an overall risk ratio of 0.11 (95% confidence interval; 0.04-0.18). Only one study investigated functional outcome, using ADL as measurement, but found no significant difference. No studies investigated PROM. In general, the studies were assessed to be of poor quality mainly due possible bias and confounding. CONCLUSION: A posterior tilt ≥20° leads to a higher risk of reoperations in uFNF. Even though the studies were of poor quality, the results suggest that we should include the measurement of posterior tilt in national guidelines.

Streamlining brain tumor surgery care during the COVID-19 pandemic: A case-control study.

BACKGROUND: The COVID-19 pandemic forced a reconsideration of surgical patient management in the setting of scarce resources and risk of viral transmission. Herein we assess the impact of implementing a protocol of more rigorous patient education, recovery room assessment for non-ICU admission, earlier mobilization and post-discharge communication for patients undergoing brain tumor surgery. METHODS: A case-control retrospective review was undertaken at a community hospital with a dedicated neurosurgery and otolaryngology team using minimally invasive surgical techniques, total intravenous anesthesia (TIVA) and early post-operative imaging protocols. All patients undergoing craniotomy or endoscopic endonasal removal of a brain, skull base or pituitary tumor were included during two non-overlapping periods: March 2019-January 2020 (pre-pandemic epoch) versus March 2020-January 2021 (pandemic epoch with streamlined care protocol implemented). Data collection included demographics, preoperative American Society of Anesthesiologists (ASA) status, tumor pathology, and tumor resection and remission rates. Primary outcomes were ICU utilization and hospital length of stay (LOS). Secondary outcomes were complications, readmissions and reoperations. FINDINGS: Of 295 patients, 163 patients were treated pre-pandemic (58% women, mean age 53.2±16 years) and 132 were treated during the pandemic (52% women, mean age 52.3±17 years). From pre-pandemic to pandemic, ICU utilization decreased from 92(54%) to 43(29%) of operations (p<0.001) and hospital LOS≤1 day increased from 21(12.2%) to 60(41.4%), p<0.001, respectively. For craniotomy cohort, median LOS was 2 days for both epochs; median ICU LOS decreased from 1 to 0 days (p<0.001), ICU use decreased from 73(80%) to 29(33%),(p<0.001). For endonasal cohort, median LOS decreased from 2 to 1 days; median ICU LOS was 0 days for both epochs; (p<0.001). There were no differences pre-pandemic versus pandemic in ASA scores, resection/remission rates, readmissions or reoperations. CONCLUSION: This experience suggests the COVID-19 pandemic provided an opportunity for implementing a brain tumor care protocol to facilitate safely decreasing ICU utilization and accelerating discharge home without an increase in complications, readmission or reoperations. More rigorous patient education, recovery room assessment for non-ICU admission, earlier mobilization and post-discharge communication, layered upon a foundation of minimally invasive surgery, TIVA anesthesia and early post-operative imaging are possible contributors to these favorable trends.

Room for Improvement: The Trephination Procedure for Pediatric Patients with Pilonidal Disease.

BACKGROUND: Pilonidal disease is common amongst adolescent males and females and often leads to recurrent symptoms and life-altering morbidity. The traditional surgical approach includes wide excision of the involved area and carries a high rate of postoperative morbidity. A minimally invasive surgical approach using trephines was described by Gips in 2008 and has since been widely adopted by many surgeons. The aim of this study was to explore outcomes of the trephination procedure for pediatric and adolescent patients by evaluating postoperative wound healing and disease recurrence. MATERIALS AND METHODS: A retrospective cohort study for patients that underwent the trephination procedure as part of standard of care for the treatment of pilonidal disease from November 1, 2019-November 1, 2020 was performed. Patient demographics, presenting characteristics, and previous treatment history were identified. Outcome measures included healing time, recurrent disease, and need for reoperation. RESULTS: A total of 19 patients underwent the trephination procedure at a mean age of 16.4 years of age. An average of 3.8 pits were excised and there were no reported intraoperative complications. Following trephination, 26.3% of patients were healed at 30-day's, with just over 40% showing complete healing by 6-months. The recurrence rate was 16.1% at 6-months and approximately 15% of patients required a second surgery. CONCLUSION: Early results for trephination at our institution show a high rate of healing complications and frequent reoperation. Future research is needed to establish the role of the trephination procedure in the context of defining the best practices for treating this challenging disease.
