Purpose
Acute kidney injury (AKI) is a serious postoperative complication, negatively impacting mortality rates, extending length of stay, and raising hospital costs. The purpose of this study was to examine AKI following open ventral hernia repair (OVHR) using a large, heterogeneous database to determine the incidence and identify risk factors for this complication.Methods
Using the 2005–2012 ACS-NSQIP database, patients undergoing open ventral hernia repair were identified by CPT codes. Patients with acute kidney injury within 30 days of surgery were compared to controls by multivariate logistic regression across preoperative and intraoperative characteristics.Results
Of 48,629 open ventral hernia repair patients identified in the dataset, AKI developed in 1.4 % (681 patients). Multivariate logistic regression determined a number of factors associated with AKI. These include WHO Class III obesity (OR = 2.57, p < 0.001), history of cardiovascular disease (OR = 1.81, p < 0.001), diabetes (OR = 1.29, p = 0.028), hypoalbuminemia (OR = 1.42, p = 0.004), and chronic kidney disease (for a baseline GFR of 60?89 mL/min/1.73m2, OR = 1.62, p = 0.001; for 30?59 mL/min/1.73m2, OR = 2.25, p < 0.001; for 15?29 mL/min/1.73m2, OR = 4.96, p < 0.001). Intraoperative factors include prolonged operative time (for ≥1SD above the mean, OR = 1.68, p = 0.002; for ≥2SD above the mean, OR = 2.76, p < 0.001) and intraoperative transfusion (OR = 2.44, p < 0.001).Conclusions
Patients with a history of obesity, chronic kidney disease, cardiovascular history, diabetes, and hypoalbuminemia are at increased risk for AKI when undergoing OVHR. Intraoperative variables such as prolonged operative times and blood transfusions may also suggest increased risk. Preoperative identification of patients with these characteristics and perioperative hemodynamic stabilization are important first steps to minimize this complication.2.
Purpose
Insulin-like growth factor 1 (IGF1) gene single nucleotide polymorphism (rs5742612) has been associated with adolescent idiopathic scoliosis (AIS) in several studies with limited sample size and inconsistent outcomes. So we perform this meta-analysis to assess the precise association between IGF1 gene single nucleotide polymorphism (rs5742612) and AIS.Methods
We systematically searched Pubmed, Embase, Web of Science and Cochrane Library up to January 19, 2016 to obtain relevant studies using our research strategy. Four articles all belonging to case–control studies were included in our meta-analysis.Results
A total of four studies containing 763 cases and 559 controls satisfied the inclusion criteria after judgment by two reviewers. No significant associations were detected between IGF1 gene single nucleotide polymorphism (rs5742612) and AIS (T vs. C, OR = 1.10, 95 % CI 0.91–1.34, p = 0.32; TT vs. CC: OR = 1.28, 95 % CI 0.82–2.02, p = 0.28; TC vs. CC: OR = 1.29, 95 % CI 0.82–2.06, p = 0.27; TT/TC vs. CC: OR = 1.28, 95 % CI 0.83–1.98, p = 0.27; TT vs. TC/CC: OR = 1.06, 95 % CI 0.82–1.36, p = 0.66).Conclusions
IGF1 gene single nucleotide polymorphism (rs5742612) is not significant associated with susceptibility to AIS in either Asian or Caucasian populations. However, IGF1 gene rs5742612 may be associated with severity of AIS. Further studies with larger sample size and different population groups involving the relationship are required to confirm the potential association.3.

Background
Emergency digestive surgery is being increasingly performed in elderly patients. The aim of the present study was to identify the predictors of mortality and morbidity following emergency digestive surgery in patients aged 80 years and older.Methods
A single-center retrospective review was performed of consecutive patients aged ≥65 years operated for a digestive surgical emergency between January 2011 and December 2013. Two groups were compared: group A (aged 65–79 years) and group B (aged ≥80 years).Results
The study population included 185 patients: 76 patients in group A and 109 in group B. The mean age was 79.9 years (65–104 years). The overall 90-day mortality rate was 23.2 and 31.9% at 1 year, which was similar between groups. The overall morbidity was 28.6%. No differences were noted between the two groups in overall, minor (Dindo I–II) or major (Dindo III–IV) morbidity rates. Multivariate analysis identified pulmonary disease (odds ratio, OR = 6.43, p = 0.02), bowel ischemia (OR = 11.41, p = 0.01), postoperative ICU stay (OR = 7.37, p < 0.0001) and the occurrence of postoperative complications (OR = 2.66, p = 0.03) as predictors of 90-day mortality. Predictors of in-hospital morbidity were preoperative hemoglobin <12 g/dL (OR = 2.49, p = 0.02) and postoperative intensive care unit (ICU) stay (OR = 6.69, p < 0.0001). An age ≥80 year was not associated with mortality or morbidity in this study.Conclusions
The decision to perform abdominal surgery in the emergency setting should be based on physiological status, which accounts for a patient’s comorbidities and health status, rather than on chronological age per se.4.

Purpose
Although the uptake of active surveillance (AS) appears to be increasing in published series, the uptake in most geographic regions remains largely unknown. Our aim was to examine practice patterns around the use of AS in low-risk prostate cancer in Canada. In addition, we examined regional variations in AS uptake, predictors of AS uptake, and persistent use for 12 months.Methods
This is a retrospective multicentre review of low-risk patients who underwent a prostate biopsy in 2010 in six centres in four provinces (BC, QC, MB and ON). AS was identified based on chart review and required a minimum of 6 months of follow-up after diagnosis without any active treatment.Results
Of 986 patients, 781 patients (mean age 64 years) were incident cases and over three-quarters (77.3 %) chose AS at diagnosis. There were significant differences in uptake of AS by centre (range 65.0–98.0 %, p ≤ 0.05). Key multivariate predictors of pursuing AS included older age (OR 1.34, p = 0.044), centre (p = 0.021), lower number of cores (OR 1.09, p = 0.025), lower number of positive biopsy cores (OR 0.52, p < 0.001), and lower percent core involvement (OR 0.84, p < 0.001). In total, 516 (85.4 %) men remained on AS over 12 months. Maintenance with AS over 12 months differed by centre, ranging from 64.1 to 93.9 % (p = 0.001). Predictors of maintenance with AS over 12 months included older age, centre, and lower number of positive cores.Conclusions
Active surveillance is widely practiced across Canada, but important regional differences were observed. Further analyses are required to understand the root causes of differences and to determine whether AS uptake is changing over time.5.

Background
Chronic Periodontitis (CP) is a common inflammatory disease affects supporting tissues of the teeth and can lead to tooth loss. The objective of this study was to determine the relationship between polymorphisms in the IL-28B gene and chronic periodontitis in an Iranian population.Methods
Two hundred and ten CP patients and one hundred healthy subjects were enrolled in the present case-control study. The rs12979860 and rs8099917 SNPs were identified using RFLP and T-ARMS-PCR methods respectively.Results
SNP analysis revealed that the G allele of rs8099917 SNP and T allele of rs12979860 SNP increased susceptibility to CP compared to the A allele and C allele (p < 0.0001, OR = 2.712, CI = 1.783-4.126; p < 0.0001, OR = 2.538, CI = 1.784-3.613 respectively). In addition, the CT/GT, TT/GG and TT/GT haplotypes were predominant in CP patients and significantly associated with the increased risk of CP.Conclusion
IL-28B polymorphisms may be useful predictive factors for chronic periodontitis and correlated to the susceptibility to CP infection in our population.6.

Background
The urine output is an important clinical parameter of renal function and blood volume status, especially in critically ill multiple trauma patients. In the present study, the minute-to-minute urine flow rate and its variability were analyzed in hypotensive multiple trauma patients during the first 6 h of their ICU (intensive care unit) stay. These parameters have not been previously reported.Methods
The study was retrospective and observational. Demographic and clinical data were extracted from the computerized Register Information Systems. A total of 59 patients were included in the study. The patients were divided into two study groups. Group 1 consisted of 29 multiple trauma patients whose systolic blood pressure was greater than 90 mmHg on admission to the ICU and who were consequently deemed to be hemodynamically compromised. Group 2 consisted of 30 patients whose systolic blood pressure was less than 90 mmHg on admission to the ICU and who were therefore regarded as hemodynamically uncompromised.Results
The urine output and urine flow rate variability during the first 6 h of the patients’ ICU stay was significantly lower in group 2 than in group 1 (p < 0.001 and 0.006 respectively). Statistical analysis by the Pearson method demonstrated a strong direct correlation between decreased urine flow rate variability and decreased urine output per hour (R = 0.17; P = 0.009), decreased mean arterial blood pressure (R = 0.24; p = 0.001), and increased heart rate (R = 0.205; p = 0.001).Conclusion
These findings suggest that minute-to-minute urine flow rate variability is a reliable incipient marker of hypovolemia and that it should therefore take its place among the parameters used to monitor the hemodynamic status of critically ill multiple trauma patients.7.
Purpose
Trauma care poses many challenges in small hospitals in rural settings. This report was designed to assess the role of a rural general surgeon with trauma patients.Methods
A cohort study was designed using a retrospective analysis of a cohort at Bozk?r Community Hospital that included trauma patients admitted to the emergency department between June 2007 and May 2009. The patients of group 1 were those treated during the first year of the study period, when the hospital staff was only non-specialist physicians. In the second year, a general surgeon was added to the staff, and the patients from this period constituted group 2.Results
The top three leading causes of injuries were falls (46.5 %), piercing/cutting injuries (38.2 %), and assault (6.5 %). The frequency of trauma due to falls was higher in group 1, and assault and piercing/cutting injuries were higher in group 2 (p < 0.001 for each). The percentage of discharged and transferred patients was not significantly different between groups (p = 0.065 and p = 0.082, respectively). Similar mortality rates were also detected (group 1: 0.5 %, group 2: 0.3 %, p = 0.479).Conclusions
The presence of a solo general surgeon was not found to be adequate for improving the outcome for trauma patients in a rural hospital.8.

Background
The incidence of osteoporosis and rotator cuff tears increases with age. Cement augmentation of bones is an established method in orthopedic and trauma surgery.Questions/Purposes
This study analyses if polymethylmethacrylate or bioabsorbable cement can improve the primary stability of a bioabsorbable suture anchor in vitro in comparison to a non-augmented suture anchor in osteoporotic human humeri.Methods
The trabecular bone mineral density was measured to ensure osteopenic human specimens. Then the poly-l-lactic acid Bio-Corkscrew® FT was implanted in the greater tuberosity footprint with polymethylmethacrylate Refobacin® cement augmentation (n = 8), with Cerament? Bone Void Filler augmentation (n = 8) and without augmentation (n = 8). Using a cyclic testing protocol, the failure loads, system displacement, and failure modes were recorded.Results
The Cerament? augmented Bio-Corkscrew® FT yielded the highest failure loads (206.7 N), followed by polymethylmethacrylate Refobacin® augmentation (206.1 N) and without augmentation (160.0 N). The system displacement was lowest for Cerament? augmentation (0.72 mm), followed by polymethylmethacrylate (0.82 mm) and without augmentation (1.50 mm). Statistical analysis showed no significant differences regarding the maximum failure loads (p = 0.1644) or system displacement (p = 0.4199). The main mode of failure for all three groups was suture slippage.Conclusion
The primary stability of the Bio-Corkscrew® FT is not influenced by bone cement augmentation with polymethylmethacrylate Refobacin® or with bioabsorbable Cerament? in comparison to the non-cemented anchors. The cement augmentation of rotator cuff suture anchors in osteoporotic bones remains questionable since biomechanical tests show no significant advantage.9.
Background
Tube thoracostomy (TT) can be an effective therapy for thoracic pathologies. Ineffective placement of TT is common and associated with significant complications. Complications require additional interventions to repair damaged tissues or replace dysfunctional TT. We hypothesize that complicated TT insertion increases cost to the hospital system.Methods
Adult trauma patients requiring TT at a level 1 trauma center (2012–2013) were reviewed. Intraoperative or image-guided TT placements were excluded. Baseline demographics and TT insertion cost (normalized and assigned by hospital billing records) were recorded. Costs included initial TT equipment, radiographs, and subsequent operative or radiologic intervention to correct TT complications. Complications were categorized using previously validated method. Secondary outcomes included: number of TT inserted, number of chest radiographs performed, and TT dwell time utilizing a standardized TT discontinuation protocol.Results
A total of 154 patients with 246 TT were included. Ninety TT (37%) had complication. Complication categories are postremoval (n = 15, 16.7%), insertional (n = 13, 14.4%), positional (n = 62, 68.9%). Overall median complicated TT cost was 9 times greater than uncomplicated TT insertion, p = 0.001. Insertional complications median cost 21 times greater than an uncomplicated, due to operative and radiologic interventions (p = 0.0001). Positional and postremoval complication rates increased median cost by 3 times compared to uncomplicated TT (p = 0.03). Operative or radiologic interventions (n = 10) were performed for organ injury or uncontrolled hemo-/pneumothorax. Increased dwell time median [IQR] was associated with complicated TT compared to uncomplicated 3 [1–5] versus 2 [1–3], p = 0.01.Conclusion
TT is a common procedure. TT complications are often considered benign. However, patients with a complicated TT insertion, especially related to insertional subtypes, have markedly increased hospitalization costs due to need for operative or radiologic repair.Level of evidence
Level V—retrospective study.Study type
This is a retrospective single-institution study.10.
Purpose
Massive bleeding usually leads to critically low levels of clotting factors, including fibrinogen. Although reduced fibrinogen levels correlate with increased mortality, predictors of hypofibrinogenemia have remained poorly understood. We investigated whether findings available on admission can be used as predictors of hypofibrinogenemia.Methods
We retrospectively reviewed serum fibrinogen levels tested on arrival in 290 blunt trauma patients transported to a level I trauma center during a 3-year period. The primary outcome was prehospital predictors for hypofibrinogenemia. Covariates included age, sex, prehospital fluid therapy, prehospital anatomical and physiological scores, time from injury, base excess, and lactate on arrival. All variables with values of p < 0.10 in univariate analysis were included in a multivariate logistic regression model. The relationships between the variables and the 7-day mortality rate were evaluated in a Cox proportional hazards model.Results
Patient’s age [odds ratio (OR): 0.97, p < 0.001], Triage Revised Trauma Score (T-RTS) (OR: 0.81, p = 0.003), and prehospital fluid therapy (OR: 2.54, p = 0.01) were detected as independent predictors for hypofibrinogenemia in multivariate logistic regression analysis. Serum fibrinogen level [hazard ratio (HR): 0.99, p = 0.01] and T-RTS (HR: 0.77, p < 0.01) were associated with the 7-day mortality rate.Conclusion
T-RTS is considered to play an important role in predicting hypofibrinogenemia and 7-day mortality in blunt trauma patients.11.
Purpose
Colorectal perforations are a serious condition associated with a high mortality. The aim of this study was to describe the clinical characteristics and identify predictors for the surgical mortality in adult patients with colorectal perforation, thereby achieving better outcomes.Methods
A retrospective study of adult patients diagnosed with colorectal perforation operated was performed. The clinical variables that might influence the surgical mortality were first analyzed, and the significant variables were then analyzed using a logistic regression model.Results
A total of 423 patients were identified, and the surgical mortality rate was 36.9 %. The most common etiology was diverticulitis (38.2 %). The highest etiology-specific mortality was for colorectal cancer (61.5 %) and ischemic proctocolitis (59.8 %). In a logistic analysis, the significant predictors for the surgical mortality were ≥3 comorbidities (p = 0.034), preoperation American Society of Anesthesiologists score ≥4 (p = 0.025), preoperative sepsis or septic shock (p < 0.001), colorectal cancer or ischemic proctocolitis (p = 0.035), reoperation (p = 0.041), and Hinchey classification grade IV (p = 0.024).Conclusion
We demonstrated that ≥3 comorbidities, a preoperation American Society of Anesthesiologists score ≥4, preoperative sepsis or septic shock, colorectal cancer or ischemic proctocolitis, reoperation, and Hinchey classification grade IV are predictors for the surgical mortality in the adult cases of colorectal perforation. These predictors should be taken into consideration to prevent surgical mortality and to reduce potentially unnecessary medical expenses.12.
Purpose
To investigate the outcomes of patients with colorectal cancer and initially unresectable or not optimally resectable liver metastases, who were treated using the liver-first approach in the era of modern chemotherapy in Japan.Methods
We analyzed and compared data retrospectively on patients with asymptomatic resectable colorectal cancer and initially unresectable or not optimally resectable liver metastases, who were treated either using the liver-first approach (n = 12, LF group) or the primary-first approach (n = 13, PF group).Results
Both groups of patients completed their therapeutic plan and there was no mortality. Postoperative morbidity rates after primary resection and hepatectomy, and post-hepatectomy liver failure rate were comparable between the groups (p = 1.00, p = 0.91, and p = 0.55, respectively). Recurrence rates, median recurrence-free survival since the last operation, and 3-year overall survival rates from diagnosis were also comparable between the LF and PF groups (58.3 vs. 61.5 %, p = 0.87; 10.5 vs. 18.6 months, p = 0.57; and 87.5 vs. 82.5 %, p = 0.46, respectively).Conclusions
The liver-first approach may be an appropriate treatment sequence without adversely affecting perioperative or survival outcomes for selected patients.13.

Objectives
There is increasing evidence that Glasgow Prognostic Score (GPS), based on systemic inflammatory response and albumin level, is a useful predictor of overall survival in patients with various types of cancer.Methods
Patients with lung metastasis from colorectal carcinoma who underwent a lung metastasectomy from 2000 to 2015 were retrospectively investigated. Routine laboratory measurements including serum C-reactive protein (CRP), albumin, and the tumor marker carcinoembryonic antigen were performed before the metastasectomy.Results
Ninety-nine patients underwent 132 lung metastasectomy procedures during the study period. Kaplan–Meier analysis revealed that GPS (p = 0.017), number of metastases (p = 0.004), and the presence of liver metastasis (p = 0.010) were associated with overall survival, while univariate analysis selected GPS (p = 0.028), number of metastases (p = 0.005), and liver metastasis (p = 0.014) as predictive factors associated with overall survival. Multivariate analysis also indicated GPS (p = 0.004), number of metastases (p = 0.004), and liver metastasis (p = 0.013) as predictive factors associated with overall survival.Conclusion
In addition to number of metastases and liver metastasis, GPS is an important predictor of overall survival in colorectal cancer patients who undergo a lung metastasectomy.14.

Purpose
Trauma patients with diabetes mellitus (DM) represent a unique population as the acute injury and the underlying disease may both cause hyperglycemia that leads to poor outcomes. We investigated how insulin-dependent DM (IDDM) and noninsulin-dependent DM (NIDDM) impact mortality after serious trauma without brain injury.Methods
The National Trauma Data Bank (NTDB) version 7.0 was queried for all patients with moderate to severe traumatic injury [injury severity score (ISS) >9]. Patients were excluded if missing data, age <10 years, severe brain injury [head abbreviated injury scale (AIS) >3], dead on arrival or any AIS = 6. Logistic regression modeled the association between DM and mortality as well as IDDM, NIDDM and mortality.Results
Overall 166,103 trauma patients without brain injury were analyzed. Mortality was 7.6 and 4.4 % in patients with and without DM, respectively (p < 0.01). Mortality was 9.9 % for patients with IDDM and 6.7 % for NIDDM (p < 0.01). The increased mortality associated with DM was only significantly higher for DM patients in their forties (5.6 vs. 3.3 %, p < 0.01). Regression analyses demonstrated that DM (AOR 1.14, p = 0.04) and IDDM (AOR 1.46, p < 0.01) were predictors of mortality compared to no DM, but NIDDM was not (AOR 1.02, p = 0.83).Conclusions
While DM was a predictor for higher mortality after serious trauma, this increase was only observed in IDDM and not NIDDM. Our findings suggest IDDM patients who present after serious trauma are unique and attention to their hyperglycemia and related insulin therapy may play a critical role in recovery.15.
Background
Open abdomen (OA) permits the application of damage control surgery principles when abdominal trauma, sepsis, severe acute peritonitis and abdominal compartmental syndrome (ACS) occur.Methods
Non-traumatic patients treated with OA between January 2010 and December 2015 were identified in a prospective database, and the data collected were retrospectively reviewed. Patients’ records were collected from charts and the surgical and intensive care unit (ICU) registries. The Acosta “modified” technique was used to achieve fascial closure in vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) patients. Sex, age, simplified acute physiology score II (SAPS II), abdominal compartmental syndrome (ACS), cardiovascular disease (CVD) and surgical technique performed were evaluated in a multivariate analysis for mortality and fascial closure prediction.Results
Ninety-six patients with a median age of 69 (40–78) years were included in the study. Sixty-nine patients (72%) underwent VAWCM. Forty-one patients (68%) achieved primary fascia closure: two patients (5%) were treated with VAWC (37 median days) versus 39 patients (95%) who were treated with VAWCM (10 median days) (p = 0.0003). Forty-eight patients underwent OA treatment due to ACS, and 24 patients (50%) survived compared to 36 patients (75%) from the “other reasons” group (p = 0.01). The ACS group required longer mechanical ventilator support (p = 0.006), length of stay in hospital (p = 0.005) and in ICU (p = 0.04) and had higher SAPS II scores (p = 0.0002).Conclusions
The survival rate was 62%. ACS (p = 0.01), SAPS II (p = 0.004), sex (p = 0.01), pre-existing CVD (p = 0.0007) and surgical technique (VAWC vs VAWCM) (p = 0.0009) were determined to be predictors of mortality. Primary fascial closure was obtained in 68% of cases. VAWCM was found to grant higher survival and primary fascial closure rate.16.
Background
Multiple perioperative complications increase mortality risk, and certain complications synergistically increase this risk to a greater degree than might be expected if the complications were independent, but these effects are not well established.Methods
This is a retrospective cohort study of 422,827 intraabdominal general surgery patients (American College of Surgeons National Surgical Quality Improvement Program 2005–2011). Eight complications were evaluated: acute respiratory failure (ARF), acute kidney injury (AKI), sepsis/septic shock, stroke, cardiac arrest (CA), myocardial infarction (MI), deep vein thrombosis/pulmonary embolus, and transfusion. Each combination of two complications (28 total) was modeled using a Cox model for 30-day mortality, with adjustment for preoperative comorbidities and risk factors. Additive interaction was determined with the relative excess risk due to interaction (RERI). A positive RERI indicates that the mortality risk with both complications is greater than the sum of the individual mortality risks. Bonferroni correction was applied (α = 0.05/28 = 0.0018).Results
Seven combinations demonstrated positive interaction: sepsis-CA (RERI 88.1; p < 0.0001), ARF–AKI (RERI 50.5; p < 0.0001), AKI–sepsis (RERI 33.9; p < 0.0001), sepsis–stroke (RERI 33.9; p < 0.0001), ARF–stroke (RERI 32.3; p < 0.0001), AKI–MI (RERI 24.5; p = 0.0013), and ARF–sepsis (RERI 19.2; p < 0.0001). Two combinations demonstrated negative interaction: ARF–CA (RERI ?65.1; p = 0.0017) and CA-transfusion (RERI ?52.0, p < 0.0001).Conclusions
Interaction effects exist between certain complications to increase the risk of short-term mortality. ARF, AKI, sepsis, and stroke were most likely to be involved in positive interactions. Further research into the mechanisms for these effects will be necessary to develop strategies to minimize the compounding effects of multiple complications in the perioperative period.17.

Background and objectives
Hepatic resection is established as the treatment for HCC. However, patients sometimes experience early recurrence of HCC (ER HCC) after curative resection.Methods
A retrospective analysis was conducted for 193 patients with single HCC who underwent curative liver resection in our medical center between April 2000 and March 2013. We divided the cohort into two groups; early recurrence group (ER G) which experienced recurrence within 6 months after resection, and non-early recurrence group (NER G). Risk factors for ER HCC were analyzed.Results
Thirty-nine out of 193 (20.2 %) patients had ER HCC. Univariate analysis showed Glasgow prognostic score (GPS, p = 0.036), neutrophil to lymphocyte ratio (NLR, p = 0.001), level of PIVKA-II (p = 0.0001), level of AFP (p = 0.0001), amounts of blood loss (p = 0.001), operating time (p = 0.002), tumor size (p = 0.0001), stage III and IV (p = 0.0001), and microvascular invasions (portal vein: p = 0.0001 and hepatic vein: p = 0.001) to be associated with ER HCC. By multivariate analysis, there were significant differences in high NLR (p = 0.029) and high AFP (p = 0.0001) in patients with ER HCC.Conclusions
Preoperative high AFP (more than 250 ng/ml) and high NLR (more than 1.829) were independent risk factors for ER HCC.18.

Purpose
The aim of this study was to assess return-to-sport outcomes following the Latarjet–Bristow procedure.Methods
This retrospective study included all athletes <50 years old, who underwent a Latarjet–Bristow procedure for anterior shoulder instability in 2009–2012. Main criteria assessments were the number of athletes returning to any sport and the number returning to the same sport at their preinjury level. The main follow-up was 46.8 ± 9.7 months.Results
Forty-seven patients were analyzed, 46 men/1 women, mean age 27.9 ± 7.9 years. Eighteen patients practiced competitive sports and 29 recreational sports. None of them were professional athletes. One hundred percent returned to sports after a mean 6.3 ± 4.3 months. Thirty/47 (63.8 %) patients returned to the same sport at the same level at least and 10/47 (21.3 %) patients changed sport because of their shoulder. Compared to patients who returned to the same sport at the same level, patients who changed sports or returned to a lower level had practiced overhead or forced overhead sports [OR = 4.7 (1.3–16.9), p = 0.02] before surgery, experienced avoidance behavior at the final follow-up (p = 0.002), apprehension (p = 0.00001) and had a worse Western Ontario Shoulder Instability Index score and sub-items (p = 0.003) except for daily activities (p = 0.21). At the final follow-up, 45/47 (95.7 %) patients were still practicing a sport.Conclusion
All the patients returned to sports, most to their preinjury sport at the same level. Patients who practiced an overhead sport were more likely to play at a lower level or to change sport postoperatively.Level of evidence
IV, retrospective study—Case series with no comparison group.19.
Purpose
The Lichtenstein technique (LT) has been recognized as the standard treatment for inguinal hernia in adults owing to the high recurrence rates of tissue-based repairs. However, Desarda technique (DT) appeared as promising tissue-based repair that provided low incidence of recurrence without the need for implanting prosthetic or foreign materials in the inguinal canal. This meta-analysis of randomized controlled trials (RCTs) comparing DT and LT for primary inguinal hernia in adults aimed to determine which technique had better clinical outcome regarding recurrence and complication rates.Methods
A systematic literature search for RCTs comparing between DT and LT was conducted using electronic databases and Google scholar service. Patients’ characteristics, technical details, recurrence and complication rates, and time to resume daily activities were extracted from the original studies and analyzed.Results
Six RCTs comprising 2159 patients (89% males) were included. No significant difference in the incidence of recurrence between both techniques was detected (OR = 0.946; P = 0.91). The overall complication rate of LT was significantly higher than DT (OR = 1.86; P < 0.001). LT had significantly higher rates of seroma formation and surgical site infection (OR = 2.17; P = 0.007) and (OR = 2.17; P = 0.029), respectively. Postoperative pain, operation time, and time to resume normal activities were comparable in both groups.Conclusion
Both DT and LT provided satisfactory treatment for primary inguinal hernia with low recurrence rates and acceptable rates of complications that were significantly less after DT. More well-designed RCTs with longer follow-up are required for further validation of the DT.20.
