Proposal of a Multivariable Prediction Model for Graded Morbidity after Liver Resection for Colorectal Metastases.

Prognostic models to predict individual early postoperative morbidity after liver resection for colorectal liver metastases (CLM) are not available but could enable optimized preoperative patient selection and postoperative surveillance for patients at greater risk of complications. The aim of this study was to establish a prognostic model for the prediction of morbidity after liver resection graded according to Dindo. N = 679 cases of primary liver resection for CLM were retrospectively analyzed using univariable and multivariable ordinal regression analyses. Receiver operating characteristics curve (ROC) analysis was utilised to assess the sensitivity and specificity of predictions and their potential usefulness as prognostic models. Internal validation of the score was performed using data derived from 129 patients. The final multivariable regression model revealed lower preoperative levels, a greater number of units of intraoperatively transfused packed red blood cells (pRBCs), longer duration of surgery, and larger metastases to independently influence postoperatively graded morbidity. ROC curve analysis demonstrated that the multivariable regression model is able to predict each individual grade of postoperative morbidity with high sensitivity and specificity. The areas under the receiver operating curves (AUROC) for all of these predictions of individual grades of morbidity were > 0.700, indicating potential usefulness as a predictive model. Moreover, a consistent concordance in Grades I, II, IV, and V according to the classification proposed by Dindo et al. was observed in the internal validation. This study proposes a prognostic model for the prediction of each grade of postoperative morbidity after liver resection for CLM with high sensitivity and specificity using pre- and intraoperatively available variables.

Surgical site infection after digestive surgery in a single tertiary hospital in Indonesia: six years of data

BACKGROUND Surgical site infection (SSI) is responsible for increasing cost, morbidity, and mortality related to surgical operations, and has continued to be a significant problem even in hospitals with advanced facilities. This study aimed to describe the SSI among patients after digestive surgery.
 METHODS From 2012 to 2017, all abdominal surgeries with SSI in Cipto Mangunkusumo Hospital, except obstetrics and gynecology cases, were included in the study. Demographic characteristics, nutritional status, preoperative and intraoperative conditions, wound contamination/SSI type, and mortality data were reported.
 RESULTS From 4,893 abdominal surgeries during the period, 135 subjects (2.8%) developed SSI with 42.2% of cases were the clean-contaminated type. Most of the cases were males (66.7%), aged between 25–65 years old (80.0%), subjective goal assessment B (46.7%), had normal weight (57.8%), had longer duration of surgery (70.4%), and had preoperative stay between 2–15 days (65.2%). Most of the SSI patients survived (77.8%).
 CONCLUSIONS Even though the SSI in Cipto Mangunkusumo Hospital was low, it still needs improvement in preoperative care, intraoperative care, and SSI awareness. Therefore, further studies are required to understand how to reduce the incidence, risk, and SSI-related mortality.

Decompressive Craniectomy in Spontaneous Intracerebral Hemorrhage: A Comparison with Standard Craniotomy Using Propensity-Matched Analysis

Spontaneous intracerebral hemorrhage carries a poor prognosis with a 30-day mortality rate of 35%-52%. There is no standardized surgical technique for treatment of spontaneous intracerebral hemorrhage. While minimally invasive techniques are popular, there has been renewed interest in decompressive craniectomy (DC). We compared surgical and functional outcomes of standard craniotomy and DC, both with hematoma evacuation, in the surgical treatment of supratentorial spontaneous intracerebral hemorrhage. This 4-year retrospective study compared outcomes of 2 surgical techniques: standard craniotomy in group A (n= 78) and DC in group B (n= 54). To minimize bias in case selection, propensity matching was performed to match preoperative Glasgow Coma Scale score and hematoma volume (group C). Hematoma evacuation was performed in 132 patients. Mean age of patients was 53.3 years, 50.5 years, and 52.06 years in groups A, B, and C, respectively. Median preoperative Glasgow Coma Scale score was 9, 7, and 8 (P= 0.01; P= 0.45), and mean hematoma volume was 46.21 mL, 50.91 mL, and 49.90 mL. Overall mortality was 26.5%; 62.9% (n= 22) of deaths were in group A, and 37.1% (n= 13) were in group B (P= 0.69). Median modified Rankin Scale score was similar in both groups, both at discharge and at 3 months. After determining propensity scores, mortality and outcomes of matched groups remained similar. DC with hematoma evacuation does not appear to provide a significant advantage over standard craniotomy with regard to functional outcomes and mortality. DC may overcome the need for subsequent surgery in accommodating postoperative mass effect in residual bleeds and rebleeds but is associated with greater blood loss and longer operative duration.

Is robotic surgery feasible at a safety net hospital?

Robotic surgery offers potential advantages of improved ability to complete procedures using a minimally invasive approach, recovery, and clinical outcomes. It has been previously established that safety net hospitals are outliers for surgical complications. As such, the adoption of new technology may not achieve the same outcomes as other institutions. We hypothesized that, compared to laparoscopic and open surgeries, robotic surgeries have fewer post-operative Clavien-Dindo complications at our safety net hospital. All robotic surgeries performed from 2017 to 2019 at a single, safety net hospital were reviewed. Cases were matched 1:3 to laparoscopic controls. Surgeries commonly performed open were additionally matched 1:3 to open counterparts. The primary outcome was Clavien-Dindo complications at 90 days post-operatively. Secondary outcomes included inadvertent enterotomy, conversion to open, operative duration, wound class, surgical site infection (SSI), surgical site occurrence (SSO), length of stay (LOS), reoperation, readmission, and recurrence. A total of 160 robotic surgeries were included and matched to 480 laparoscopic surgeries and 108 open surgeries. Open surgeries were associated with greater risk of Clavien-Dindo complication (OR = 2.7, p = 0.040, 95% confidence interval 1.0-6.9) than either robotic or laparoscopic surgeries. Robotic cases had increased operative duration when compared to laparoscopic (p < 0.001) but not open cases (p = 0.093). No difference was seen in enterotomy, conversion to open, SSI, SSO, LOS, reoperation, readmission, or recurrence between robotic and laparoscopic, and robotic and open cases. Robotic surgery is safe and feasible at a safety net hospital. Robotic and laparoscopic surgeries were associated with fewer Clavien-Dindo complications than open surgery, but no differences were seen between robotic and laparoscopic cases. Robotic surgery, compared to both laparoscopic and open surgery, had longer operative durations. Further studies are needed to assess the value of robotic as opposed to laparoscopic surgery in a safety net setting.

Vaginal Hysterectomy in a Large Health Maintenance Organization: Retrospective Application of a Clinical Algorithm

The primary objective was to describe practice patterns of benign hysterectomy within a large community health maintenance organization (HMO) and evaluate clinical and surgeon characteristics associated with the performance of vaginal hysterectomy (VH). Secondary objectives were to retrospectively apply a VH algorithm to determine how our practice patterns conform, and compare rates of perioperative complications among patients who did and did not meet the algorithm. Patient and surgeon characteristics, and perioperative complications, were compared between patients who underwent VH and did or did not meet the VH algorithm. Retrospective cohort study. Large community HMO. Women undergoing benign hysterectomy. None. Route of hysterectomy, patient and surgeon characteristics, perioperative complications. One hundred and thirty-one of 984 (13.3%) benign hysterectomies from January 1, 2013 to June 30, 2015 were vaginal. Patients who were vaginally parous, Hispanic, had normal preoperative uterine size and documentation of uterine descent were more likely to have VH (all p <.05). High-volume surgeons performed 18.8% of their hysterectomies vaginally, as compared to low-volume surgeons who performed 11.4% of their hysterectomies vaginally (p <.01). VH were more likely to be performed by surgeons with longer practice durations than non-vaginal hysterectomies (16.3 vs 12.2 years, p <.01). Seventy-five percent of patients who met the VH algorithm underwent non-vaginal hysterectomy and they had longer operative durations and higher rates of postoperative complications compared to patients who underwent VH. Conversely, patients who underwent VH despite not meeting the VH algorithm did not have significantly different rates of perioperative complications or blood loss than patients who met the VH algorithm. Seventy-five percent of patients deemed appropriate for VH by our algorithm underwent non-vaginal hysterectomy and had more postoperative complications and longer operative durations. Our data suggest that surgeon characteristics, including surgical volume and duration of practice, may explain some of this performance gap. These findings contribute additional insight into current practice patterns and describe clinical factors that should be included in VH algorithms.

A Novel Technique for the Removal of Elastic Intramedullary Nail in Pediatric Long Bones: A Technical Note.

Elastic stable intramedullary nails have been commonly used to treat unstable long bone fractures in children. The nail tip at the insertion site can cause problems. The nail tip should be of optimal length as a prominent nail tip or a short nail tip, or both, may cause different sets of problems. If the nail tip is short, nail removal after fracture union can be difficult and may pose challenges. A short nail tip may lead to difficulty in nail removal, longer duration of surgery, and need for special equipment for extracting the nail. Few techniques have been suggested in the past for removing elastic nail with the short tip, but all these techniques need special instruments. We describe a surgical technique using a metallic suction cannula to aid elastic nail removal. This method utilizes an easily available instrument in the operating room and does not need any special equipment.

Investigation of recurrent laryngeal palsy rates for potential associations during thyroidectomy.

There are many clinical associations and potential mechanisms of injury resulting in recurrent laryngeal nerve palsy (RLNP) after thyroidectomy. One possible cause of RLNP is focal intralaryngeal compression of the recurrent laryngeal nerve (RLN), which may be associated with the tracheal tube (TT). Therefore, we examined current RLNP rates to investigate potential associations, including intralaryngeal, airway, anaesthetic and anthropometric factors. We analysed 1003 patients undergoing thyroid surgery at The Alfred from 2010 to 2017, who had anatomically intact RLNs at the conclusion of thyroidectomy. All included patients underwent pre- and post-operative flexible nasendoscopy. The primary outcome was RLNP rate. We analysed potential associated factors including age, sex, operative time, surgical indication, pathology, American Society of Anaesthesiologists Physical Status, Mallampati scores, body mass index, intubation grade, TT size and specimen weight. The independent risk factors were identified by logistic regression analysis. Overall, RLNP occurred in 83 patients (8.3%) of which one was permanent (0.1%). On univariate analysis, RLNP was associated with male sex (P = 0.02), and duration of surgery (P = 0.002). On multivariate analysis, both male sex (P = 0.047) and duration of surgery (P = 0.04) remained significant. Further, factors postulated to cause intralaryngeal compression of the RLN, including TT size, body mass index, intubation grade and Mallampati score, were not significantly associated with RLNP. Our study showed a RLNP rate of 8.3%, and associations with longer operative duration, and male sex. Potential intralaryngeal factors were not identified.

Trends in hospital readmissions and emergency room visits 60 days after robotic-assisted and laparoscopic hysterectomy

ObjectiveHospital readmission after surgery is one of the major contributors to the increased healthcare cost. Robotic-assisted hysterectomy (RAH) is an innovative surgical procedure most commonly performed within the last decade. The purpose of this study was to analyze the effects on hospital readmission patterns and emergency room (ER) visits within 60 days of discharge for women who had RAH versus laparoscopic hysterectomy (LH) in an academic community hospital in Texas. MethodWe performed a retrospective study of women with RAH or LH. We used the univariate and multivariate logistic regression to examine the impact of patients' risk factors, the type of surgery, age, number of comorbidities, and duration of surgery on the 60-day hospital readmissions and ER visits. ResultsA total of 291 cases with RAH or LH for benign and malignant indications were examined. The number of comorbidities and duration of surgery were similar between the two treatment groups (p > 0.05). Patients in the RAH group were younger than the LH group (RAH: 45.4 ± 9.9 y, LH: 49.8 ± 11.5 y, p < 0.05). No significant difference neither in hospital readmission or ER visits between the two groups was observed (p = 0.544 and p = 0.109, respectively). Younger age and longer duration of surgery were significantly associated with a higher risk of ER visits (p < 0.05). ConclusionRAH is comparable with LH in hospital readmissions and ER visits. The younger age and longer operation time could lead to ER visits.

Early Onset of Postoperative Gastrointestinal Dysfunction Is Associated With Unfavorable Outcome in Cardiac Surgery: A Prospective Observational Study.

Objective:The distribution of postoperative gastrointestinal (GI) dysfunction and its association with outcome were investigated in cardiac surgery patients. Gastrointestinal function was evaluated using the Acute Gastrointestinal Injury (AGI) grade proposed by the European Society of Intensive Care Medicine.Design:Prospective observational study at a single center.Setting:University hospital.Patients:Consecutive patients presenting for elective cardiac surgery with extracorporeal circulation (ECC).Interventions:None.Results:Daily assessment using the AGI grade was performed on the first 3 postoperative days in addition to standard care. For analysis, 3 groups were formed based on the maximum AGI grade: AGI 0, AGI 1, and AGI ≥2. Five hundred and one patients completed the study; 32.7%, 65.1%, and 2.2% of the patients scored a maximum AGI 0, AGI 1, and AGI ≥2, respectively. Patients with AGI grade ≥2 had more frequently undergone thoracic aortic surgery and had longer surgery duration and time on ECC. Patients with AGI grade ≥2 had statistically significant higher frequency of GI complications within 30 days (63.6% vs 1.2% and 5.5% in patients with AGI 0 and AGI 1) and higher 30-day mortality (9.1% vs 0.0% and 1.8% in patients with AGI 0 and AGI 1).Conclusions:Early GI dysfunction following cardiac surgery was associated with an unfavorable outcome. Increased attention to GI dysfunction in cardiac surgery patients is warranted and the AGI grade could be a helpful adjunct to a structured approach.

Impact of Regional Block Failure in Ambulatory Hand Surgery on Patient Management: A Cohort Study.

Regional anesthesia (RA) is an anesthetic technique essential for the performance of ambulatory surgery. Failure rates range from 6% to 20%, and the consequences of these failures have been poorly investigated. We determined the incidence and the impact of regional block failure on patient management in the ambulatory setting. This retrospective cohort study includes all adult patients who were admitted to a French University Hospital (Hôpital Saint-Antoine, AP-HP) between 1 January 2016 and 31 December 2017 for unplanned ambulatory distal upper limb surgery. Univariate and stepwise multivariate analyses were performed to determine factors associated with block failure. Among the 562 patients included, 48 (8.5%) had a block failure. RA failure was associated with a longer surgery duration (p = 0.02), more frequent intraoperative analgesics administration (p < 0.01), increased incidence of unplanned hospitalizations (p < 0.001), and a 39% prolongation of Post-Anesthesia Care Unit (PACU) length of stay (p < 0.0001). In the multivariate analysis, the risk factors associated with block failure were female sex (p = 0.04), an American Society of Anesthesiologists (ASA) score > 2 (p = 0.03), history of substance abuse (p = 0.01), and performance of the surgery outside of the specific ambulatory surgical unit (p = 0.01). Here, we have documented a significant incidence of block failure in ambulatory hand surgery, with impairment in the organization of care. Identifying patients at risk of failure could help improve their management, especially by focusing on providing care in a dedicated ambulatory circuit.

Occurrence and management of postoperative pneumocephalus using the semi-sitting position in vestibular schwannoma surgery

BackgroundThe semi-sitting position in neurosurgical procedures is still under debate due to possible complications such as venous air embolism (VAE) or postoperative pneumocephalus (PP). Studies reporting a high frequency of the latter raise the question about the clinical relevance (i.e., the incidence of tension pneumocephalus) and the efficacy of a treatment by an air replacement procedure.MethodsThis retrospective study enrolled 540 patients harboring vestibular schwannomas who underwent posterior fossa surgery in a supine (n = 111) or semi-sitting (n = 429) position. The extent of the PP was evaluated by voxel-based volumetry (VBV) and related to clinical predictive factors (i.e., age, gender, position, duration of surgery, and tumor size).ResultsPP with a mean volume of 32 ± 33 ml (range: 0–179.1 ml) was detected in 517/540 (96%) patients. The semi-sitting position was associated with a significantly higher PP volume than the supine position (40.3 ± 33.0 ml [0–179.1] and 0.8 ± 1.4 [0–10.2], p < 0.001). Tension pneumocephalus was observed in only 14/429 (3.3%) of the semi-sitting cases, while no tension pneumocephalus occurred in the supine position. Positive predictors for PP were higher age, male gender, and longer surgery duration, while large (T4) tumor size was established as a negative predictor. Air exchange via a twist-drill was only necessary in 14 cases with an intracranial air volume > 60 ml. Air replacement procedures did not add any complications or prolong the ICU stay.ConclusionAlthough pneumocephalus is frequently observed following posterior fossa surgery in semi-sitting position, relevant clinical symptoms (i.e., a tension pneumocephalus) occur in only very few cases. These cases are well-treated by an air evacuation procedure. This study indicates that the risk of postoperative pneumocephalus is not a contraindication for semi-sitting positioning.

X-ray-free ultrasound-guided versus fluoroscopy-guided percutaneous nephrolithotomy: a comparative study with historical control

PurposeTo compare the outcomes and complications of supine X-ray-free ultrasound-guided percutaneous nephrolithotomy (XG-PCNL) with fluoroscopy-guided (FG)-PCNL in both prone and supine positions.MethodsThis was a comparative study that included a prospective cohort and historical control groups. This study analysed 40 consecutive patients who undergone supine XG-PCNL between October 2019 and March 2020. The control groups were composed of historical control formed from the last 40 consecutive patients who underwent FG-PCNL in both supine and prone positions from our PCNL database from January 2018 and September 2019. Patients’ demographics, stone characteristics and intraoperative and postoperative outcomes were compared.ResultsA total of 120 patients were classified into the supine XG-PCNL, supine FG-PCNL, and prone FG-PCNL groups (each N = 40). They had similar baseline characteristics and initial stone burden. The supine XG-PCNL group had higher puncture attempts, nephrostomy tube placement, and longer surgery duration than both the supine and prone FG-PCNL groups. However, the stone-free rate was similar in all groups (85%, supine XG-PCNL; 72.5%, supine FG-PCNL; 77.5% prone FG-PCNL; p = 0.39). No significant difference was found in the complication rate and length of stay among the three groups.ConclusionSupine XG-PCNL is an alternative to both supine and prone FG-PCNL with similar efficacy and complication rates for kidney stone patients. This could be a good alternative to urological centres with no access to fluoroscopy.

Postoperative Hypothermia in Surgical Patients at Azadi Teaching Hospital

Introduction: The sensation to cold, shake occurrence and shivering are events that are commonly developed following general anesthesia administration postoperatively. Hypothermia has been considered as the most frequent outcome of surgery underwent by anesthesia. Inadvertent hypothermia has been taken into account as common side effect in the postoperative period immediately and it is related to wide impairments and anomalies of different body organs. Concentration on predictive factors of hypothermia would be important to reduce the incidence rate and correct preventable unnecessary risks for patients in the health settings following surgical operations. The aim of study is to assess the magnitude and associated factors of postoperative hypothermia recovery room in patients underwent general anesthesia. Methods: A hospital based prospective cross-sectional study was conducted on200patients with different age groups of both genders who underwent a scheduled non-cardiac surgery and general anesthesia consecutively during the period between the October 1stand the November1st2016. Results: The study revealed that the overall core hypothermia in the study sample was31%. The study showed that the post-operative temperatures decreased statistically significantly in all study patients and separately in adults, children, males, or females P&lt;0.001. The study also revealed that the operation duration(p=0.045)and pre-operative temperature P&lt;0.001were predictors of post-operative hypothermia in study sample. Conclusions: The incidence of hypothermia among study sample was not so high. A significant reduction in core body temperature of patients between pre and post-operation times was found. Those patients with longer operation duration, lower room temperature, and lower pre-operative temperature were at more risk of post-operative hypothermia.

Efficacy of Thiol Disulfide Homeostasis and Ischemia Modified Albumin Values in Estimating the Degree of Difficulty for Laparoscopic Cholecystectomy.

The aim of this study was to investigate the efficacy of thiol disulfide homeostasis and Ischemia Modified Albumin (IMA) values in predicting the technical difficulties that might be encountered during laparoscopic cholecystectomy. The study included 65 patients who underwent laparoscopic cholecystectomy due to cholelithiasis at the General Surgery Clinic of Ankara Numune Training and Research Hospital. All patients' demographic data, previous history of cholecystitis, a history of chronic illness, preoperative white blood count (WBC), liver function tests (AST, ALT), amylase and lipase levels, intra-operative adhesion score, the ultrasonographic appearance of gall bladder, duration of hospital stay, duration of operation, thiol disulfide and IMA values were evaluated. Native thiol and total thiol averages were higher in patients without a history of cholecystitis, and on the other hand, disulfide, disulfide/native thiol rate, disulfide/total thiol rate, native thiol/total thiol rate and IMA averages were higher in patients with a history of cholecystitis. While there was a statistically significant negative correlation between native and total thiol values and age, duration of surgery and duration of hospital stay; IMA, disulfide, disulfide/Total thiol, Native/Total thiol and disulfide/Native thiol rates were higher in older patients with a longer duration of surgery and hospital stay. In addition, preoperative IMA, disulfide, disulfide/Total thiol, Native/Total thiol and disulfide/Native thiol were observed to increase as the degree of intraoperative pericholecystic adhesion increased. We believe that the evaluation of thiol disulfide homeostasis and IMA parameters prior to laparoscopic cholecystectomy can be used as an effective method for predicting intraoperative difficulties.

Neuropraxia: An Underappreciated Morbidity of Liver Transplantation

BackgroundPeripheral nerve injuries can be devastating complications of surgery, potentially resulting in severe functional disability and decreased quality of life. Long surgeries with considerable tissue manipulation, for example, liver transplantation, may present increased risk; however, neuropraxia in transplantation has not been well investigated. Materials and methodsThis is a retrospective study of all adult patients undergoing liver transplantation at a large academic center between January 2013 and December 2015. Descriptive analyses, logistic regressions, and forward selection procedures were used to determine the odds of developing neuropraxia and associated factors. ResultsOf the 283 liver recipients, the mean age was 55.8 y, 35.1% were female, 65.6% were Caucasian, 8.9% were African American, 16.7% were Hispanic, and mean model for end-stage liver disease sodium score at transplant was 24.2 ± 10.9. The underlying etiology was alcohol (26.2%), hepatitis C (34.8%), nonalcoholic steatohepatitis (13.1%), and other (14.2%). The incidence of neuropraxia after liver transplantation was 8.3% (n = 25), with 60% (n = 16) upper extremities, 82% left sided, and 84% male. There was no difference in age, race, body mass index, hypertension, diabetes, hyperlipidemia, or smoking in those with neuropraxia versus those without. In multivariate analysis, neuropraxia was significantly associated with male gender, lower model for end-stage liver disease score, and longer duration of surgery (P < 0.05). Symptoms lasted median 5 d, with a wide range up to 187 d. Neuropraxia-specific treatment (physical therapy or medications) was required in 32% (n = 9). ConclusionsPeripheral nerve injuries are an unexplored complication of liver transplantation. Although transient, a high number (8.2%) of patients developed neuropraxia, negatively affecting their ability for recovery. Exploration of mechanisms for minimizing risk and intraoperative detection and prevention should be considered to mitigate this complication.

Incidence & Risk Factors of Postoperative Delirium After Spinal Surgery in Older Patients

Although postoperative delirium is a common complication in older patients, few papers have described risk factors after of spinal surgery. The purpose of this study was to analyze various perioperative risk factors for delirium after spinal surgery in older patients. This study was performed on retrospective data collection with prospective design. We analyzed 138 patients over 65 years of age who underwent spinal surgery. Preoperative factors were cognitive function (Mini-Mental State Examination-Korean (MMSE-K) and the Korean version of the Delirium Rating Scale-Revised-98 (K-DRS 98)), age, sex, type of admission, American Society of Anesthesiologist classification, metabolic equivalents, laboratory findings, visual analog scale, and Oswestry Disability Index. Intraoperative factors were operation time, blood loss, and type of procedure. Postoperative factors were blood transfusion and type of postoperative pain control. Postoperative delirium developed in 25 patients (18.16%). Patients were divided into two groups: Group with delirium (group A) and group without delirium (group B). MMSE-K scores in Group A were significantly lower than in Group B (p < 0.001). K-DRS 98 scores were significantly higher in Group A than Group B (p < 0.001). The operation time was longer in Group A than Group B (p = 0.059). On multivariate regression analysis, the odds ratio of K-DRS 98 was 2.43 (p = 0.010). After correction for the interaction between age and MMSE-K, patients younger than 73 years old had a significantly lower incidence of delirium with higher MMSE-K score (p = 0.0014). Older age, low level of preoperative cognitive function, long duration of surgery, and transfusion were important risk factors of postoperative delirium after spinal surgery. It is important to recognize perioperative risk factors and manage appropriately.

Preventing iatrogenic facial pressure ulcers during spinal surgery: Prospective trial using a novel method and review of literature.

To assess the outcome of a novel method of preventing facial pressure ulcers in spinal surgery and a review of literature. A prospective trial using a novel method of facial protection using paraffin tulle gras dressing to cover bony prominences during spinal surgical procedures was performed. Patients were reviewed at 24 hours and 6 weeks. A telephone survey was also conducted post discharge. Over an 8-month period, 12 patients (7F:5M, age 9-72 years) underwent spine surgery for tumour stabilisation (n = 7), deformity correction (n = 4), and degenerative presentation (n = 1) with mean operative time of 472 minutes (range 150-785 minutes) in prone position. All patients were managed by the same team using an agreed protocol. No pressure ulcers were noted in our study. One patient sustained minimal erythema, which resolved after 24 hours. All patients were satisfied with the care received. Facial pressure ulcers though much reduced are still common in spinal surgery. The common factors are the long duration of surgery, shear, friction, moisture, and intrinsic factors. Our strategy of an appropriate facial support and constant vigilance helped eliminate the incidence of iatrogenic facial ulcers in spinal surgery.

OS-MRS as a predictor of hospital length of stay – a retrospective audit of patients submitted to elective gastric bypass surgery

Background: Obesity is an important public health problem, with a high prevalence worldwide. Bariatric surgery emerged as an effective therapeutic tool, with improvement of quality of life and a decrease in all-cause mortality. Obesity Surgery Mortality Risk Score (OS-MRS) predicts 90-day mortality after bariatric surgery, but its association with hospital length of stay (LOS) has not been elucidated. We aimed to evaluate the association between OS-MRS and LOS after gastric bypass surgery.&#x0D; Methodology: We retrieved clinical and demographic data of 474 patients who had been submitted to gastric bypass surgery for this retrospective audit at Hospital de Santo António, Centro Hospitalar Universitário do Porto, Porto, (Portugal), between January 2010 and May 2015. The patients were classified as Class A, B or C. The primary goal was to evaluate whether there was an association between OS-MRS and LOS after gastric bypass surgery. The study of the relationship between duration of surgery (DS) and LOS was also performed.&#x0D; Results: After application of exclusion criteria, 402 patients were included in the statistical analysis (172 patients Class A, 187 Class B and 43 Class C). Patients classified as OS-MRS Class A had a significant shorter LOS (3.5 ± 2.3 days) than patients classified as Class B (4.2 ± 5.1 days) and Class C (5.7 ± 12.6 days; p&lt;0.001). A significant positive correlation between DS and LOS was observed, although the degree of that correlation was weak (ρ=0.203; p=0.001).&#x0D; Conclusion: A positive association of OS-MRS with hospital length of stay and duration of surgery was observed; the patients with higher OS-MRS classes had longer length of stay in the hospital and longer duration of surgery. Moreover, longer length of stay was slightly associated with longer surgery duration.&#x0D; Citation: Miguel DS, Ramos P, Oliveira J, Ferreira C, Cruz F.

Failure of enhanced recovery after surgery in laparoscopic colorectal surgery: a systematic review.

Enhanced recovery after surgery programs has been applied extensively in laparoscopic colorectal surgery. However, several studies have found that some patients fail from ERAS programs. It is important to identify these patients so that remedial action can be taken in a timely manner. The aim of this study was to perform a systematic review of ERAS failure and related risk factors following laparoscopic colorectal surgery. A literature search of the PubMed, EMBASE, OVID, and Cochrane databases was performed. The search strategy involved terms related to ERAS, failure, and colorectal surgery. The main outcomes were definitions of ERAS failure and related risk factors. Seven studies including 1463 patients were analyzed. The definition of ERAS failure was mostly associated with a prolonged postoperative length-of-stay (poLOS). Twenty-four kinds of identified risk factors were divided into three parts, the operative part, the pathophysiological part, and the ERAS elements, of which operative factors including more intraoperative blood loss and longer operative duration were the most frequently identified. ERAS failure was mostly related to a prolonged poLOS, and operative factors were the most frequently identified risk factors for ERAS failure following laparoscopic colorectal surgery. These findings will help physicians to take remedial action in a timely manner. Nonetheless, high-quality randomized controlled trials following a standardized framework for evaluating ERAS programs are needed in the future.
