A cohort study of the morbidity of combined anterior-posterior cervical spinal fusions: incidence and predictors of postoperative dysphagia

Purpose

To identify risk factors that may lead to the development of dysphagia after combined anterior and posterior (360°) cervical fusion surgery.

Methods

A single center, retrospective analysis of patients who had same-day, 360° fusion at Henry Ford Hospital between 2008 and 2012 was performed. Variables analyzed included demographics, medical co-morbidities, levels fused, and degree of dysphagia.

Results

The overall dysphagia rate was 37.7 %. Patients with dysphagia had a longer mean length of stay (p < 0.001), longer mean operative time (p < 0.001), greater intraoperative blood loss (p = 0.002), and fusion above the fourth cervical vertebra, C4, (p = 0.007). There were no differences in the rates of dysphagia when comparing patients undergoing primary or revision surgery (p = 0.554).

Conclusion

Prolonged surgery and fusion above C4 lead to higher rates of dysphagia after 360° fusions. Prior anterior cervical fusion does not increase the risk of dysphagia development.

     

The distribution of infection with <Emphasis Type="Italic">Propionibacterium acnes</Emphasis> is equal in patients with cervical and lumbar disc herniation

Background

Cervical and back pains are important clinical problems affecting human populations globally. It is suggested that Propionibacterium acnes (P. acnes) is associated with disc herniation. The aim of this study is to evaluate the distribution of P. acnes infection in the cervical and lumbar disc material obtained from patients with disc herniation.

Methods and material

A total of 145 patients with mean age of 45.21 ± 11.24 years who underwent micro-discectomy in cervical and lumbar regions were enrolled into the study. The samples were excited during the operation and then cultured in the anaerobic incubations. The cultured P. acnes were detected by 16S rRNA-based polymerase chain reaction.

Results

In this study, 145 patients including 25 cases with cervical and 120 cases with lumbar disc herniation were enrolled to the study. There was no significant difference in the age of male and female patients (p = 0.123). P. acnes infection was detected in nine patients (36%) with cervical disc herniation and 46 patients (38.3%) with lumbar disc herniation and no significant differences were reported in P. acnes presence according to the disc regions (p = 0.508.). Moreover, there was a significant difference in the presence of P. acnes infection according to the level of lumbar disc herniation (p = 0.028).

Conclusion

According to the results, the presence of P. acnes is equal in patients with cervical and lumbar disc herniation. There was a significant difference in the distribution of P. acnes infection according to level of lumbar disc herniation.

Short-term outcomes and one surgeon’s learning curve for thoracoscopic esophagectomy performed with the patient in the prone position

Purpose

Thoracoscopic esophagectomy with the patient in the prone position (TEP) is now being performed as minimally invasive esophagectomy for esophageal cancer. This study examines the short-term outcomes and the learning curve associated with TEP.

Methods

One surgeon (“Surgeon A”) performed TEP on 100 consecutive patients assigned to three periods based on treatment order. Each group consisted of 33 or 34 patients. The outcomes of the three groups were compared to define the influence of surgeon expertise.

Results

Outcomes improved as Surgeon A gained experience in performing this operation, as evidenced by reduced thoracic operative times between periods 1 and 2, and then between periods 2 and 3 (p = 0.0033 and p = 0.0326, respectively); an increased number of retrieved chest nodes between periods 1 and 2 (p = 0.0070); and a decline in recurrent laryngeal nerve (RLN) palsy between periods 2 and 3 (p = 0.0450). Period 2 was the pivotal period for each learning curve.

Conclusions

An individual surgeon’s learning curve over the course of 100 TEP procedures had three outcomes: a shortened operative time, a higher number of retrieved chest nodes, and a decreased rate of RLN palsy. Approximately 30–60 cases were needed to reach a plateau in the TEP procedure and a reduction in the morbidity rate.

     

The feasibility of transpedicular screw fixation of the subaxial cervical spine in the Arab population: a computed tomography-based morphometric study

Background

Transpedicular screw fixation of the cervical spine provides excellent biomechanical stability. The feasibility of inserting a 3.5-mm screw in the pedicle requires a minimum pedicle diameter of 4.5 mm. This diameter allows at least 0.5 mm bony bridge medially and laterally in order to avoid pedicle violation which can result in neurovascular complications. We aim to evaluate the feasibility of this technique in Arab people since no data are available about this population.

Materials and methods

This cross-sectional study involved a retrospective review of computed tomography scans of normal cervical spines of 99 Arab adults. Ten morphometric measurements were obtained. Data were analyzed using a p value of ≤0.05 as the cut-off level of statistical significance.

Results

Our sample included 63 (63.6 %) males and 36 (36.4 %) females, with a mean age of 35.5 ± 16.5 years. The morphometric parameters of C3–C7 spine pedicles were larger in males than in females. The outer pedicle width (OPW) was <4.5 mm in >25 % of all subjects at C3–C6 vertebrae. Statistically significant differences in the OPW between males and females were noted at C3 (p = 0.032) and C6 (p = 0.004).

Conclusions

Inserting pedicle screws in the subaxial cervical spine is feasible among the majority of Arab people.

The effectiveness of FloSeal® matrix hemostatic agent in thyroid surgery: a prospective,randomized, control study

Background

The objective of this study was to compare the effectiveness of FloSeal® matrix hemostatic agent with hemostatic surgical procedures and Tabotamp® in thyroid surgery.

Methods

One hundred fifty-five consecutive total thyroidectomy patients were recruited at our institution between January 2005 and December 2007. Exclusion criteria were applied. Patients were randomized to one of three hemostatic approaches: 49 received surgical procedures only, and 52 received oxidized regenerated cellulose patch (Tabotamp Fibrillar 2.5?×?5 cm) and 54 FloSeal (5,000 U/5 mL). The same surgeon performed all operations.

Results

Mean operating time was reduced in the FloSeal group (105 min) vs. surgical (133 min, p?=?0.02) and vs. Tabotamp (122 min, p?=?0.0003). Also, wound drain removal occurred earlier with FloSeal (p?=?0.006 vs. surgical; p?=?0.008 vs. Tabotamp) resulting in shorter postoperative hospital stay in the FloSeal group (p?=?0.02 vs. surgical; p?=?0.002 vs. Tabotamp).

Conclusions

FloSeal matrix is an effective additional agent to conventional haemostatic procedures in thyroid surgery.

     

Oxidative stress markers in type 2 diabetes patients with diabetic nephropathy

Background

Epidemiological studies show that 5–40 % of type 2 diabetes (T2DM) patients have diabetic nephropathy, and oxidative stress is one of several underlying mechanisms. We investigated associations between oxidative stress markers and severity of diabetic nephropathy.

Methods

Fifty-nine T2DM patients from the endocrinology outpatient department were included, and their levels of oxidative stress markers were measured. Three groups were determined by their urine albumin-to-creatinine ratio (UACR): group A (UACR < 30 mg/g, n = 22); group B (30 ≤ UACR < 300 mg/g, n = 22); and group C (UACR ≥ 300 mg/g, n = 15).

Results

Vitamin C levels correlated negatively and moderately with serum creatinine (γ = ?0.459, p < 0.001), urine albumin (γ _s = ?0.458, p = 0.001) and UACR (γ _s = ?0.408, p = 0.001), but only weakly with hydroxy-2-deoxyguanosine (8-OHdG) and estimated glomerular filtration rate (eGFR). Vitamin C levels decreased as 8-OHdG, serum creatinine, albumin and UACR increased. T2DM patients with more severe diabetic nephropathy had lower vitamin C levels.

Conclusion

Our results identified several oxidative stress markers that may be clinically important in diabetic nephropathy. Studies with larger sample sizes should be undertaken to confirm these findings.

     

Major perioperative complications after spine surgery in patients with cerebral palsy: assessment of risk factors

Purpose

A prospective, longitudinal cohort was studied to determine the incidence, consequences, and risk factors of major perioperative complications in patients with cerebral palsy (CP) treated with spinal fusion. There is a wide variety of data available on the complications of spine surgery; however, little exists on the perioperative complications in patients with CP.

Methods

A prospective multicenter dataset of consecutive patients with CP treated with spinal fusion was evaluated. All major perioperative complications were identified and stratified into categories: pulmonary, gastrointestinal, other medical, wound infection, neurological, instrumentation related, and unplanned staged surgery. Univariate and multivariate analyses were performed to identify various risk factors for major perioperative complications.

Results

127 patients were identified with a mean age of 14.3 ± 2.6 years. Overall, 39.4 % of the patients had a major perioperative complication. Occurrence of a complication [no complication (NC), yes complication (YC)] resulted in significantly increased intensive care unit (ICU) (NC = 3.2 days, YC = 7.8 days, p < 0.05) and hospital stays (NC = 7.7 days, YC = 15.6 days, p < 0.05). Variables associated with greater risk of a complication included: increased estimated blood loss (EBL) (p < 0.001), larger preoperative kyphosis (p = 0.05), staged procedures (p < 0.05), a lack of antifibrinolytic use (p < 0.05), and a trend toward lower body mass index (BMI) (p = 0.08). Multivariate regression analysis revealed an increased EBL as independently associated with a major perioperative complication (p < 0.05).

Conclusions

In this cohort of patients with CP who underwent spinal fusion, 39.4 % experienced a major perioperative complication, with pulmonary being the most common. The occurrence of a major perioperative complication lengthened both ICU and hospital stay. Risk factors for major perioperative complications included greater preoperative kyphosis, staged procedures, a lack of antifibrinolytic use, and increased EBL, with the latter being an independent predictor of a major perioperative complication.

Usefulness of Inflammation-Based Prognostic Score in Patients Undergoing Lung Metastasectomy for Colorectal Carcinoma

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.

     

Feasibility of the liver-first approach for patients with initially unresectable and not optimally resectable synchronous colorectal liver metastases

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.

     

Native tissue repair or transvaginal mesh for recurrent vaginal prolapse: what are the long-term outcomes?

Introduction and hypothesis

The objective of this study was to assess outcomes in native tissue (NT) and transvaginal mesh (TVM) repair in women with recurrent prolapse.

Methods

A retrospective two-group observational study of 237 women who underwent prolapse repair after failed NT repair in two tertiary hospitals. A primary outcome of “success” was defined using a composite outcome of no vaginal bulge symptoms, no anatomical recurrence in the same compartment beyond the hymen (0 cm on POPQ) and no surgical re-treatment for prolapse in the same compartment. Secondary outcomes assessed included re-operation for prolapse in the same compartment, dyspareunia and mesh-related complications.

Results

Of a total of 336 repairs, 196 were performed in the anterior compartment and 140 in the posterior compartment. Compared with the TVM groups, women undergoing repeat NT repair were more likely to experience anatomical recurrence (anterior 40.9 % vs 25 %, p?=?0.02, posterior 25.3 % vs 7.5 %, p?=?0.01), report vaginal bulge (anterior 34.1 % vs 12 %, p?<?0.01, posterior 24.1 % vs 7.5 %, p 0.02) and had a higher prolapse re-operation rate (anterior 23.9 % vs 7.4 %, p?<?0.01, posterior 19.5 % vs 7.5 %, p?=?0.08). Using composite outcomes, the success rate was higher with TVM repair in both compartments (anterior 34.2 % vs 13.6 %, p <0.01, posterior 56.6 % vs 23.0 %, p <0.01). Re-operations for mesh exposure were 9.3 % anteriorly and 15.1 % posteriorly. Although the number of women requiring a prolapse re-operation is lower in the TVM group, the overall re-operation rate was not significantly different when procedures to correct mesh complications were included.

Conclusions

Although the success rate is better with the use of TVM for recurrent prolapse, the total re-operation rates are similar when mesh complication-related surgeries are included.

     

Factors associated with adverse postoperative outcomes in patients with long bone post-traumatic osteomyelitis

Aims

To evaluate short-term clinical and functional outcomes following operative treatment of long bone post-traumatic osteomyelitis (PTOM).

Methods

We retrospectively analyzed a consecutive cohort of 142 adult patients undergoing operative treatment of long bone PTOM at our Level I trauma center over a 10-year study period. In addition to subjective patient evaluations, surveyed postoperative outcomes included incidence of residual infection, fracture malunion or nonunion, and requirement for limb amputation. All included patients had a minimum follow-up of 12 months postoperatively.

Results

Patients suffering an adverse postoperative outcome tended to have a higher incidence of polymicrobial infection (25.4 vs. 11.4%, p = 0.042) and requirement for skin grafting (58.1 vs. 37.9%, p = 0.024) and free-flap procedures (43.6 vs. 19.5%, p = 0.003) compared to those achieving complete healing. Sequential administration of parenteral and oral antibiotic therapies was associated with a reduced incidence of adverse postoperative outcome (p = 0.047).

Discussion

Patients with long bone PTOM and extensive soft tissue defects often fail to develop complete remission of their symptoms by 12 months postoperatively. Sequential administration of parenteral and oral antibiotics may help to limit infection recurrence. Further research is required to inform optimal treatment strategy.

     

Analysis of cervical sagittal alignment variations after lumbar pedicle subtraction osteotomy for severe imbalance: study of 59 cases

Objective

To evaluate postoperative changes within the cervical alignment following surgical lumbar correction by pedicle subtraction osteotomy (PSO) in patients affected with sagittal global malalignment disease.

Methods

This was a monocentric, radiographic, and prospective study. 79 patients, who underwent sagittal correction by PSO, performed an EOS imaging pre- and postoperatively between January 2008 and December 2013 at the University Hospital of Bordeaux. Inclusion criteria were a performed pre- and postoperative EOS imaging and a preoperative C7SVA > 5 cm. Were excluded patients who did not allow EOS with a viewable cervical spine due to hyperkyphosis. The study involved the analysis of pelvic, lumbar, thoracic, cervical, and cranial parameters before and after the surgery.

Results

59 patients met the criteria. Mean follow-up was 38 months. The lumbar PSO significantly improved sagittal alignment including L1S1 lordosis, T1T12 kyphosis, and C7SVA (p < 0.001). We did not reported a significant change within cervical parameters after PSO (C2C7 lordosis 22.7°–21.5° p = 0.64, C1C7 lordosis 50.6°–48.8° p = 0.56, C1C2 angle 28.2°–27.9° p = 0.82, C7 slope stayed constant 32.3°–30.5° p = 0.47, OC2 angle 15.54°–15.56° p = 0.99). However, cranial slope decreased significantly (p < 0.05). We did not find correlation between lumbar lordosis and cervical lordosis variations (R = 0.265). Cervical lordosis was highly correlated with the C7 slope (R = 0.597) and with the Spino Cranial Angle (R = ? 0.867).

Conclusion

Reciprocal changes in cervical spine after PSO are difficult to approach. Maintaining a horizontal gaze involves locoregional mechanisms of compensation adapting to the slope of C7. The cranial system by decreasing the cranial slope allows the gaze alignment and is the first compensation mechanism to get involved after a loss of lumbar lordosis. Restoring optimal C7SVA is necessary to prevent the development of secondary cervical painful symptomatology when the cranial compensation is outdated.

     

Interest of intra-operative 3D imaging in spine surgery: a prospective randomized study

Purpose

We report a single-center, prospective, randomized study for pedicle screw insertion in opened and percutaneous spine surgeries, using a computer-assisted surgery (CAS) technique with three-dimensional (3D) intra-operative images intensifier (without planification on pre-operative CT scan) vs conventional surgical procedure.

Material and method

We included 143 patients: Group C (conventional, 72 patients) and Group N (3D Fluoronavigation, 71 patients). We measured the pedicle screw running time, and surgeon’s radiation exposure. All pedicle runs were assessed according to Heary by two independent radiologists on a post-operative CT scan.

Results

3D Fluoronavigation appeared less accurate in percutaneous procedures (24 % of misplaced pedicle screws vs 5 % in Group C) (p = 0.007), but more accurate in opened surgeries (5 % of misplaced pedicle screws vs 17 % in Group C) (p = 0.025). For one vertebra, the average surgical running time reached 8 min in Group C vs 21 min in Group N for percutaneous surgeries (p = 3.42 × 10^?9), 7.33 min in Group C vs 16.33 min in Group N (p = 2.88 × 10^?7) for opened surgeries. The 3D navigation device delivered less radiation in percutaneous procedures [0.6 vs 1.62 mSv in Group C (p = 2.45 × 10^?9)]. For opened surgeries, it was twice higher in Group N with 0.21 vs 0.1 mSv in Group C (p = 0.022).

Conclusion

The rate of misplaced pedicle screws with conventional techniques was nearly the same as most papers and a little bit higher with CAS. Surgical running time and radiation exposure were consistent with many studies. Our work hypothesis is partially confirmed, depending on the type of surgery (opened or closed procedure).

     

The effect of subscapularis tenotomy in athletes operated on for recurrent anterior shoulder dislocation

Purpose

Some authors consider preservation of the subscapularis tendon as one of the most important elements for a successful long-term outcome in patients operated on with open capsulorrhaphy for recurrent anterior shoulder dislocation. The purpose of this study was to evaluate whether vertical tenotomy of the subscapularis tendon might affect internal rotation strength recovery in patients operated on with open capsulorrhaphy for recurrent anterior shoulder dislocation.

Methods

Ninety-six patients were retrospectively followed up at a mean of 72.5 months. They underwent clinical evaluation, Rowe and Walch–Duplay scoring scales, the Visual Analog Scale (VAS), and dynamometric measurements (side-to-side) of internal and external rotation, forward elevation, and abduction. All patients were athletes: 25% were practising risk-free sports, 44% contact sports, 14.5% sports with cocking of the arm, and 14.5% high-risk sports activities.

Results

Five (5.2%) recurrences were registered, and all patients returned to pre-operative sports activity. The Rowe score was 98.12, the Walch–Duplay score 92.25, and the VAS score 0.1. Dynamometric assessment showed no significant differences (side-to-side) in internal rotation (p = 0.34), external rotation (p = 0.9), flexion (p = 0.7), and abduction (p = 0.7). Dominant arms showed better results than non-dominant arms (p < 0.01).

Conclusion

Complete tenotomy of the subscapularis tendon does not seem to negatively affect internal rotation strength recovery or external rotation movement in athletes.

     

Risk factors for complications after diverting ileostomy closure in patients who have undergone rectal cancer surgery

Purpose

To clarify the risk factors for complications after diverting ileostomy closure in patients who have undergone rectal cancer surgery.

Methods

The study group comprised 240 patients who underwent a diverting ileostomy at the time of lower anterior resection or internal anal sphincter resection, in our department, between 2004 and 2015. Univariate and multivariate analyses of 18 variables were performed to establish which of these are risk factors for postoperative complications.

Results

The most common complications were intestinal obstruction and wound infection. Univariate analysis showed that an age of 72 years or older (p?=?0.0028), an interval between surgery and closure of 6 months or longer (p?=?0.0049), and an operation time of 145 min or longer (p?=?0.0293) were significant risk factors for postoperative complications. Multivariate analysis showed that age (odds ratio, 3.4236; p?=?0.0025), the interval between surgery and closure (odds ratio, 3.4780; p?=?0.0039), and operation time (odds 2.5179; p?=?0.0260) were independent risk factors.

Conclusions

Age, interval between surgery and closure, and operation time were independent risk factors for postoperative complications after diverting ileostomy closure. Thus, temporary ileostomy closure should be performed within 6 months after surgery for rectal cancer.

     

Factors that regulate spinal cord position after expansive open-door laminoplasty

Introduction

Although appropriate dorsal migration of the spinal cord is a desired end point of cervical laminoplasty, it is difficult to predict in advance the spinal cord position after surgery and to control it during surgery. The aim of the present study was to investigate the factors that affect postoperative spinal cord position after cervical laminoplasty using multivariable analysis.

Materials and methods

We retrospectively assessed 56 consecutive patients with cervical spondylotic myelopathy treated by open-door laminoplasty. The postoperative anterior space of the spinal cord was measured at 204 levels, and its maximum value was measured at 56 levels within the decompressed area. To identify the factors that regulate the postoperative spinal cord position, we evaluated seven radiological parameters, including the C3–C7 lordosis angle (LA), LA of the decompressed area, C3–C7 spinal cord lordosis angle (SCLA), SCLA of the decompressed area, spinal canal sagittal diameter at C5, number of expanded lamina, and postoperative dural sac diameter.

Results

The postoperative anterior space of the spinal cord was 5.5 ± 1.4 mm, and its maximum value was 6.4 ± 1.3 mm. A multiple linear regression analysis revealed that the number of expanded laminae (standardized partial regression coefficient: β = 0.17, p = 0.009) and dural sac diameter (β = 0.43, p < 0.001) was significantly associated with anterior space of the spinal cord. Although these parameters were also significantly associated with the maximum value, their relative contributions were reversed; β = 0.49 (p < 0.001) for the number of expanded laminae and 0.25 (p = 0.029) for the dural sac diameter.

Conclusions

The number of expanded laminae and dural sac diameter was significantly associated with the spinal cord position after laminoplasty. These factors could help to predict spinal cord position following laminoplasty and achieve adequate indirect decompression of the spinal cord.

     

Prognostic value of urinary cytology and other biomarkers for recurrence and progression in bladder cancer: a prospective study

Purpose

Urinary cytology (C) and cystoscopy remain the gold standard for the detection and screening of bladder cancer (BC). In this prospective study, we analyzed whether baseline C, ImmunoCyt (I), BTA Stat (B), hemoglobin dipstick (H), and NMP22 BladderChek (N) can predict recurrence and progression.

Methods

Urinary samples from 91 patients with BC were prospectively collected over an 18-month period. Baseline characteristics of the population included patient demographics, various clinicopathological variables and use of intravesical therapy. Progression and recurrence were then assessed after a median follow-up of 48 months (IQR 23.7–59.5). Univariate and multivariate analyses were performed using COX proportional hazards models.

Results

On univariate analysis, C (HR 1.36; p = 0.26), I (HR 0.89; p = 0.66), B (HR 0.80; p = 0.42), H (HR 0.75; p = 0.30), and N (HR 0.82; p = 0.48) were not associated with recurrence-free survival (RFS). With regard to progression-free survival (PFS), C was significantly prognostic (HR 2.67; p = 0.017), whereas I, B, H, and N were not. On multivariable analysis, NMP22 was the only marker to be independently associated with RFS (HR 0.41, p < 0.01) and PFS (HR 0.32, p = 0.02).

Conclusion

Based on the results of this study, baseline C, B, I, and H were not independently prognostic. Prognostic impact of NMP22 requires further validation in a multicenter larger study.

     

Comparison of pain management after laparoscopic distal gastrectomy with and without epidural analgesia

Purpose

The optimal analgesia following laparoscopic distal gastrectomy (LDG) has not been determined; moreover, it has been unclear whether epidural anesthesia has benefits for laparoscopic surgery. In this study, we evaluated the effectiveness of epidural analgesia after LDG.

Methods

This retrospective study included 84 patients who underwent LDG for gastric cancer. Patients received either combined thoracic epidural and general anesthesia (Epidural group, n = 34) or general anesthesia alone (No epidural group, n = 50). We recorded data on the patients, surgery, postoperative outcomes and anesthesia-related complications.

Results

In the Epidural group, the first day of flatus was significantly earlier (2.21 vs. 2.44 days, p = 0.045) and the number of additional doses of analgesics was significantly lower (2.85 vs. 4.86 doses, p = 0.007) than in the No epidural group. Postoperative urinary retention occurred at a significantly higher rate in the Epidural group (n = 7; 20.6 %) than in the No epidural group (p < 0.001).

Conclusion

Epidural anesthesia may reduce the need for additional analgesics after LDG, but increases the risk of urinary retention.

     

Trends in Procedures at Major Trauma Centres in New South Wales,Australia: An Analysis of State-Wide Trauma Data

Objectives

To describe the trend in major trauma surgical procedures and interventional radiology in major trauma patients in Australia over the past 6 years.

Methods

This was a retrospective review of adult major trauma (Injury Severity Score greater than 15) patients using the New South Wales Statewide Trauma Registry between 2009 and 2014. Major trauma surgical procedures were classified into abdominal, neurosurgery, cardiothoracic and interventional radiology. The proportion of patients undergoing such procedures per year was the outcome of interest.

Results

There were around ten thousand cases analysed. The proportion of cases undergoing interventional radiology procedures increased from 1% in 2009 to around 6% in 2014. Other major trauma surgical procedures remained stable. Only around 100 laparotomies were performed in 2014. The predictors of having an IR procedure performed were increasing from 2009 (OR 1.5 95% CI 1.4, 1.6 p < 0.001), hypotension (OR 1.5 95% CI 1.1, 2.1 n = 0.01), severe abdominal injury (OR 4.2 95% CI 3.2, 5.3 p < 0.001) and lower limb (including pelvic) injury (OR 3.8 95% CI 3.0, 4.7 p < 0.001).

Conclusion

There has been a rapid increase in the use of interventional radiology over the past few years which will need to be addressed in future trauma service planning and models of care.

     

A prospective,randomized trial comparing thulium vapoenucleation with holmium laser enucleation of the prostate for the treatment of symptomatic benign prostatic obstruction: perioperative safety and efficacy

Introduction and objectives

To compare the perioperative outcomes of thulium vapoenucleation of the prostate (ThuVEP) with holmium laser enucleation of the prostate (HoLEP) for patients with symptomatic benign prostatic obstruction (BPO).

Methods

Forty-eight and 46 patients were prospectively randomized to ThuVEP and HoLEP. All patients were assessed preoperatively and 4-week postoperatively. The complications were noted and classified according to the modified Clavien classification system. Patient data were expressed as median (interquartile range) or numbers (%).

Results

Median age at surgery was 73 (67–76) years and median prostate volume was 80 (46.75–100) cc and not different between the groups (p = 0.207). The median operative time was 60 (41–79) minutes without significant differences between both groups (p = 0.275). There were no significant differences between the groups regarding catheterization time [2 (2–2) days, p = 0.966] and postoperative stay [2 (2–3) days, p = 0.80]). Clavien 1 (13.8%), Clavien 2 (3.2%), Clavien 3a (2.1%), and Clavien 3b (4.3%) complications occurred without significant differences between the groups. However, the occurrence of acute postoperative urinary retention was higher after HoLEP compared to ThuVEP (15.2 vs. 2.1%, p ≤ 0.022). At 1-month follow-up, peak urinary flow rates (10.7 vs. 22 ml/s), post-void residual volumes (100 vs. 20 ml), International Prostate Symptom Score (20 vs. 10) and Quality of Life (4 vs. 3) had improved significantly (p ≤ 0.005) without significant differences between the groups.

Conclusions

ThuVEP and HoLEP are safe and effective procedures for the treatment of symptomatic BPO. Both procedures give equivalent and satisfactory immediate micturition improvement with low perioperative morbidity.
