¿Puede la cirugía mínimamente invasiva resultar en sitios inusuales de metástasis?

ObjectiveTo compare sites of metastasis for the laparoscopic (LRC) and open (ORC) approaches in a cohort of patients at a district general hospital. Morbidity and mortality for the two approaches are assessed using secondary outcomes of length of stay and complication rate. Metastasis rate and site are compared.MethodsA retrospective case note review was carried out for all patients who underwent cystectomy for bladder malignancy at Pinderfields General Hospital, Wakefield between 2010 and 2016 (n = 219). There were 150 males and 69 females in 107 minimally invasive cases and 87 open (missing data on 25 cases). Data were analysed using Microsoft Excel XLSTAT.ResultsRecurrence rate was 25.1% and did not differ significantly with approach (p = 0.89). Sites of recurrence did not differ with operative approach, the most frequent being pelvis, chest and bone. Unusual sites of recurrence included abdominal wall and sigmoid colon which both occurred in LRC. Length of stay was greater for the open approach (median LRC = 10, ORC = 13, p < 0.01). Five-year survival was 74.9%. Survival distribution did not significantly differ with operative approach (p = 0.43), and there was no significant association between operative approach and patient death within the follow-up period (p = 0.09). Stricture rate was 4.1% and was not significantly different between the two groups (p = 0.29). Median time to stricture was 130 days. Clavien-Dindo scores for complications did not differ with approach (p = 0.93), and there was no significant association between operative approach and whether complications developed (p = 0.19).ConclusionsThe adverse oncological outcomes in minimally invasive approaches suggested by some studies are not confirmed here. Those in the LRC group were discharged sooner, though this did not translate into differences in morbidity or survival. Analysis of the association between individual complications and length of stay may clarify this further. Shorter hospital stay is also likely to have significant financial implications.Despite no significant difference in outcomes, the findings demonstrate potential benefits of LRC. Extensions of this study could include: cost-benefit analysis, examination of individual complications’ effect on length of stay; and analysis of approach-specific factors contributing to perioperative deaths.     

Unique challenges and outcomes of young women with breast cancers from a tertiary care cancer centre in India

BackgroundYoung (≤40 years) breast cancers (YBC) are uncommon, inadequately represented in trials and have unique concerns and merit studying.MethodsThe YBC treated with a curative intent between 2015 and 2016 at our institute were analysed.ResultsThere were 1228 patients with a median age of 36 (12–40) years; 38 (3.1%) had Stage I, 455 (37.1%) - II, 692 (56.3%) –III, and remaining 43 (3.5%) Stage IV (oligo-metastatic) disease; 927 (75.5%) were node positive; 422 (34.4%) were Triple negatives (TNBC), 331 (27%) were HER-2 positive. There were 549 (48.2%) breast conservations and 591 (51.8%) mastectomies of which 62 (10.4%) underwent breast reconstruction. 1143 women received chemotherapy, 617 (53.9%) received as neoadjuvant and 142 (23.1%) had pathological complete response; 934 (81.9%) received adjuvant radiotherapy. At the median follow-up of 48 (0–131) months, 5-year overall and disease-free survival was 79.6% (76.8–82.5) and 59.1% (55.8–62.6). For stage I, II, III and IV, the 5-year overall-survival was 100%, 86.7% (82.8–90.6), 77.3% (73.4–81.2), 69.7% (52.5–86.9) and disease-free survival was 94% (85.9–100), 65.9% (60.3–71.5), 55% (50.5–59.5), and 29.6% (14–45.2) respectively. On multivariate analysis, TNBC and HER-2+ subgroups had poorer survival (p = 0.0035). 25 patients had BRCA mutations with a 5-year DFS of 65.1% (95% CI:43.6–86.6). Fertility preservation was administered in 104 (8.5%) patients; seven women conceived and 5 had live births. Significant postmenopausal symptoms were present in 153 (13%) patients.ConclusionMore than half of the YBC in India were diagnosed at an advanced stage with aggressive features leading to suboptimal outcomes. Awareness via national registry and early diagnosis is highly warranted. Menopausal symptoms and fertility issues are prevalent and demand special focus.     

Role of high tibial osteotomy in medial compartment osteoarthritis of the knee: Indications,surgical technique and outcomes

Knee osteoarthritis (OA) is the most common joint disorder worldwide. In particular, primary knee OA often presents with a varus malalignment. This increases the loads going through the medial compartment resulting in cartilage degeneration and symptomatic arthritis. High tibial osteotomy (HTO) is the workhorse surgical procedure for treating medial knee OA. When performed precisely in the hands of an experienced surgeon, HTO can delay or avoid knee arthroplasty. Of note, outcomes of knee arthroplasty are at best unpredictable in patients of younger age. Hence, there is a growing need for joint preservation procedures for younger patients presenting with knee OA, of which HTO is one. Through this article, the authors of whom all are joint preservation surgeons with a special interest in osteotomy hope to share from their experience as well as the available literature on the indications, perioperative planning, surgical technique, outcomes as well as pearls and pitfalls of HTO.     

Elevated neutrophil to lymphocyte ratio is associated with poor long-term survival and graft failure after lung transplantation

PurposeWe aimed to assess the prognostic value of Neutrophil to Lymphocyte Ratio (NLR) on long-term outcomes and graft dysfunction after lung transplantation.MethodsWe retrospectively reviewed all patients receiving a lung transplant at our institution from 2011 to 2014. The primary exposure was elevated NLR at the time of transplant, defined by NLR>4. The primary outcomes were graft failure and three-year all-cause mortality. Multivariate logistic regression and Kaplan-Meier survival analysis were used to analyze outcomes.Results95 patients were included. 40 patients (42%) had an elevated NLR. Elevated NLR was associated with graft failure (OR: 4.7 [1.2–18.8], p = 0.02), and three-year mortality (OR: 5.4 [1.3–23.2], p = 0.03) on multivariate logistic regression. Patients with elevated NLR demonstrated significantly lower survival on Kaplan-Meier analysis (50% versus 74%, p = 0.02). The c-statistic for our multivariate model was 0.91.ConclusionElevated neutrophil to lymphocyte ratio is associated with poor long-term survival and graft failure after lung transplantation.     

The association of Hospital Medicare beneficiary payer-mix,national quality rankings and outcomes following hepatopancreatic surgery

IntroductionWe sought to determine the impact of payer-mix on post-operative outcomes among Medicare beneficiaries following hepatopancreatic surgery.MethodsMedicare beneficiaries who underwent hepatopancreatic surgery were identified. Hospital quality markers were obtained from the Hospital General Information dataset. Hospitals were dichotomized (low/average vs. high) based on Medicare patient days versus all patient days irrespective of payer type.ResultsHigh Medicare patient-mix hospitals were more likely to be ranked higher than the national average relative to safety of care (29.4% vs. 38.1%) and timeliness of care (15.4% vs. 26.3%) versus low burden Medicare hospitals (both p < 0.001). However, Medicare beneficiaries who had hepatopancreatic surgery at a high Medicare patient-mix hospital were at higher risk of a complication (OR = 1.13, 95%CI 1.04–1.22), and death within 30-days (OR = 1.37, 95%CI 1.23–1.53) following surgery.ConclusionWhile hospitals caring for higher numbers of Medicare beneficiaries generally performed better on CMS quality indicators, these rankings did not equate to improved post-operative outcomes.     

Does Early Debridement,Antibiotic Therapy and Implant Retention (DAIR) have a Role in Managing Periprosthetic Joint Infection of the Knee in Indian Scenario: A Retrospective Analysis of Outcomes

PurposeTo report outcomes of Debridement, Antibiotic therapy and Implant Retention (DAIR) for periprosthetic knee joint infections (PJI) in the Indian population and to study factors influencing outcomes.MethodsThis was a Retrospective study of 80 cases of acute PJI after total knee arthroplasty who were treated by DAIR, within 2 weeks of onset of infection. A standardised institutional management protocol was applied to all cases. Patients were followed up for a minimum 1 year. Outcomes of DAIR were classified as successful or unsuccessful based on resolution or persistence of infection, and subsequent requirement of revision surgery. Influence of factors, like comorbidities, culture status and microbiological characteristics of causative organism, on outcomes was assessed.ResultsOverall 55 patients (68.75%) had successful eradication of infection after DAIR. 27 (33.7%) patients were culture negative and 53 (66.2%) patients grew organisms on culture. There was no statistically significant difference in outcomes (p = 0.082) between culture-positive cases (69.8% success rate) and (66.7% success rate) in culture negative cases. Furthermore, no difference in outcomes was observed in culture-positive patients between those who grew Gram-positive organisms versus Gram-negative organisms (p = 0.398) Similarly, patient comorbidities did not significantly alter the outcomes after DAIR (p = 0.732).ConclusionOur study demonstrates that early DAIR within 2 weeks of onset of infection using a standard protocol during surgery and postoperatively can result in good outcomes. Patient comorbidities, culture status (positive versus negative), Gram staining characteristics of organisms and the identity of pathogenic bacteria did not influence outcomes of DAIR for acute PJI.     

Efecto sobre el comportamiento de dexmedetomidina como premedicación anestésica en la población pediátrica: Estudio prospectivo observacional

Premedication in the pediatric population is of vital importance to reduce anxiety and facilitate anesthetic induction. Midazolam and ketamine have been used for this purpose, drugs that have shown long-term changes in neurodevelopment. Dexmedetomidine promotes a sedative, analgesic effect and lacks neurotoxic effects, its intranasal application is easy and minimally invasive. We studied the sedative and behavioral effect of intranasal dexmedetomidine 2 mcg/kg in ASA 1 and 2 children for elective surgery. They were evaluated at 10, 20 and 30 minutes of administered, in the separation of the parents and placement of the mask for inhalation induction with behavioral and sedation scores (classified from 1 to 4), we considered acceptable for admission to operating room categories 3 and 4.ResultsThirty patients between 1 and 10 years old were included in the period from September 2017 to April 2018. The sedation score obtained at 30 minutes was acceptable in 46.6% of the patients and the behavior score was in 96% of the cases. In 63% of cases the acceptance of the facial mask placement for inhalation induction was achieved. The procedure was well tolerated in all cases and parents were satisfied in 100% of the cases.     

Outcomes of patients older than 55 years undergoing abdominoplasty after bariatric surgery

BackgroundBariatric surgery has become widely performed for treating patients with morbid obesity, and the age limits are being pushed further and further as the procedure proves safe. After massive weight loss, many of those patients seek body-contouring surgery for excess skin and fat.ObjectivesTo analyze the feasibility and the safety of abdominoplasty in patients older than 55 years old after bariatric surgery.SettingUniversity hospital medical center.MethodsWe performed a retrospective review of prospectively collected data from patients aged older than 55 years who had undergone abdominoplasty following massive weight loss due to a bariatric surgery at a single institution from 2004 to 2017. The data analyzed included age, gender, preoperative body mass index, associated interventions, co-morbidities, and postoperative complications.ResultsWe retrieved records for 104 patients; 85.6% percent of them were female, and the mean age was 60.1 ± 3.9 years old. Of the 104 patients, 21 (20.2%) underwent a sleeve gastrectomy and 77 (74%) underwent a Roux-en-Y gastric bypass. The mean interval between the bariatric surgery and the abdominoplasty was 33.6 ± 26.9 months. The mean preoperative weight and body mass index were 76.1 ± 14.5 kg and 28.9 ± 4.5 kg/m², respectively. A total complication rate of 20% was observed. The only factor significantly associated with postoperative morbidity was the associated procedure (P = .03), when we performed another procedure at the same time as the abdominoplasty. Complications included postoperative bleeding in 5 patients (4.8%), seromas in 5 patients (4.8%), surgical site infections in 12 patients (11.5%), and wound dehiscence or ischemia in 2 patients (1.9%). No mortality occurred.ConclusionAbdominoplasty can be safely performed in carefully selected patients older than 55 years old after weight loss surgery, and does not present increased morbidity or mortality. We recommend that surgeons avoid adding concomitant procedures when possible, to decrease the risk of complications. It is also important to look at the patient’s previous maximum BMI levels, as a higher maximum BMI can predict higher postoperative risks and longer hospital stays.
