Minimally invasive lateral corpectomy for thoracolumbar traumatic burst fractures

OBJECTIVEThe need for anterior column reconstruction after thoracolumbar burst fractures remains controversial. Here, the authors present their experience with minimally invasive lateral thoracolumbar corpectomies for traumatic fractures.METHODSBetween 2012 and 2019, 59 patients with 65 thoracolumbar fractures underwent 65 minimally invasive lateral corpectomies (MIS group). This group was compared to 16 patients with single-level thoracolumbar fractures who had undergone open lateral corpectomies with the assistance of general surgery between 2007 and 2011 (open control group). Comparisons of the two groups were made with regard to operative time, estimated blood loss, time to ambulation, and fusion rates at 1 year postoperatively. The authors further analyzed the MIS group with regard to injury mechanism, fracture characteristics, neurological outcome, and complications.RESULTSPatients in the MIS group had a significantly shorter mean operative time (228.3 ± 27.9 vs 255.6 ± 34.1 minutes, p = 0.001) and significantly shorter mean time to ambulation after surgery (1.8 ± 1.1 vs 5.0 ± 0.8 days, p < 0.001) than the open corpectomy group. Mean estimated blood loss did not differ significantly between the two groups, though the MIS group did trend toward a lower mean blood loss. There was no significant difference in fusion status at 1 year between the MIS and open groups; however, this comparison was limited by poor follow-up, with only 32 of 59 patients (54.2%) in the MIS group and 8 of 16 (50%) in the open group having available imaging at 1 year. Complications in the MIS group included 1 screw misplacement requiring revision, 2 postoperative femoral neuropathies (one of which improved), 1 return to surgery for inadequate posterior decompression, 4 pneumothoraces requiring chest tube placement, and 1 posterior wound infection. The rate of revision surgery for the failure of fusion in the MIS group was 1.7% (1 of 59 patients).CONCLUSIONSThe minimally invasive lateral thoracolumbar corpectomy approach for traumatic fractures appears to be relatively safe and may result in shorter operative times and quicker mobilization as compared to those with open techniques. This should be considered as a treatment option for thoracolumbar spine fractures.

Objective: To estimate the efficacy of our technique of zero ischemia time partial nephrectomy (ZTPN) with hemostatic running suture and compare it to the standard technique, in terms of perioperative complications, operative time (OT) and estimated blood loss (EBL). Materials and methods: We retrospectively analysed 180 consecutive patients who underwent ZTPN using a supra 11th or supra 12th rib mini flank approach. First group numbered 90 patients treated with running suture hemostatic technique (RSHT), while the control group enrolled 90 patients in whom we performed standard reconstruction technique (SRT). According the propensity score, both groups were similar in terms of tumor size, age and PADUA score. Patients with solitary tumour limited to the kidney (T1-T2a) were included. Our technique included a running suture of surgical bed edges and closure of the renal cortex by the positioning of peri-renal fat within the cortical bed and fixation with interrupted sutures. Results: PADUA score and tumor size were comparable between groups (7.12 ± 1.33 vs 7.1 ± 2.11, p = 0.4 and 52.9 ± 14.8 vs 50.0 ± 13.2, p = 0.3). The mean operative time (OT) was significantly longer in first group (165.2 vs 95, p = 0.04), while median estimated blood loss (EBL) was significantly reduced (250 vs 460 ml, p = 0.02). Surgical resection margins were negative in 100% of cases and no patient developed a local or distant recurrence during follow up. There was significant difference in postoperative GFR value between groups (p < 0.05). Conclusions: Our technique could be safely performed in local, low volume facilities, thus reducing the need for expensive and more challenging minimal invasive surgical techniques..

Object The main aim of this study was to compare clinical and radiological outcomes after stabilization by a percutaneous transpedicular system and stabilization from the standard open approach for thoracolumbar spine injury. Methods Thirty-seven consecutive patients were enrolled in the study over a period of 16 months. Patients were included in the study if they experienced 1 thoracolumbar fracture (A3.1–A3.3, according to the AO/Magerl classification), had an absence of neurological deficits, had no other significant injuries, and were willing to participate. Eighteen patients were treated by short-segment, minimally invasive, percutaneous pedicle screw instrumentation. The control group was composed of 19 patients who were stabilized using a short-segment transpedicular construct, which was performed through a standard midline incision. The pain profile was assessed by a visual analog scale (VAS), and overall satisfaction by a simple 4-stage scale relating to performance of daily activities. Working ability and return to original occupation were also monitored. Radiographic follow-up was defined by the vertebral body index (VBI), vertebral body angle (VBA), and bisegmental Cobb angle. The accuracy of screw placement was examined using CT. Results The mean surgical duration in the percutaneous screw group was 53 ± 10 minutes, compared with 60 ± 9 minutes in the control group (p = 0.032). The percutaneous screw group had a significantly lower perioperative blood loss of 56 ± 17 ml, compared with 331 ± 149 ml in the control group (p < 0.001). Scores on the VAS in patients in the percutaneous screw group during the first 7 postoperative days were significantly lower than those in the control group (p < 0.001). There was no significant difference between groups in VBI, VBA, and Cobb angle values during follow-up. There was no significant difference in screw placement accuracy between the groups and no patients required surgical revision. There was no significant difference between groups in overall satisfaction at the 2-year follow-up (p = 0.402). Working ability was insignificantly better in the percutaneous screw group; previous working position was achieved in 17 patients in this group and in 12 cases in the control group (p = 0.088). Conclusions This study confirms that the percutaneous transpedicular screw technique represents a viable option in the treatment of preselected thoracolumbar fractures. A significant reduction in blood loss, postoperative pain, and surgical time were the main advantages associated with this minimally invasive technique. Clinical, functional, and radiological results were at least the same as those achieved using the open technique after a 2-year follow-up. The short-term benefits of the percutaneous transpedicular screw technique are apparent, and long-term results have to be studied in other well-designed studies evaluating the theoretical benefit of the percutaneous technique and assessing whether the results of the latter are as durable as the ones achieved by open surgery.

AbstractTranexamic acid (TXA) reduces surgical blood loss and alleviates inflammatory response in total hip arthroplasty. However, studies have not identified an optimal regimen. The objective of this study was to identify the most effective regimen of multiple-dose oral TXA in achieving maximum reduction of blood loss and inflammatory response based on pharmacokinetic recommendations. We prospectively studied four multiple-dose regimens (60 patients each) with control group (group A: matching placebo). The four multiple-dose regimens included: 2-g oral TXA 2 hours pre-operatively followed by 1-g oral TXA 3 hours post-operatively (group B), 2-g oral TXA followed by 1-g oral TXA 3 and 7 hours post-operatively (group C), 2-g oral TXA followed by 1-g oral TXA 3, 7 and 11 hours post-operatively (group D) and 2-g oral TXA followed by 1-g oral TXA 3, 7, 11 and 15 hours post-operatively (group E). The primary endpoint was estimated blood loss on post-operative day (POD) 3. Secondary endpoints were thromboelastographic parameters, inflammatory components, function recovery and adverse events. Groups D and E had significantly less blood loss on POD 3, with no significant difference between the two groups. Group E had the most prolonged haemostatic effect, and all thromboelastographic parameters remained within normal ranges. Group E had the lowest levels of inflammatory cytokines and the greatest range of motion. No thromboembolic complications were observed. The post-operative four-dose regimen brings about maximum efficacy in reducing blood loss, alleviating inflammatory response and improving analgaesia and immediate recovery.

Minimally invasive video-assisted thyroidectomy (MIVAT) has gained acceptance as an alternative to conventional thyroidectomy. This technique results in less bleeding, postoperative pain, shorter recovery time, and better cosmetic results without increasing morbidity. We retrospectively assessed outcomes in 583 patients having MIVAT from May 2005 to September 2014. The study population was divided into groups according to periods: 2005 to 2009 and 2010 to 2014. Operative data, complications, and length of stay were collected and compared. Total thyroidectomy was undertaken in 185, completion thyroidectomy in 49, and hemithyroidectomy in 349. Malignancy was present in 127 (21.8%). Mean incision was 3.4 ± 0.7 cm and estimated blood loss was 23.7 ± 21.7 mL. Mean operative time was 86.5 ± 39.3 minutes for all operations, 78.5 ± 37.0 minutes for hemithyroidectomy, 70.9 ± 30.1 minutes for completion thyroidectomy, and 106.8 ± 41.3 minutes for total thyroidectomy. Postoperatively, 56 (9.6%) had unilateral vocal cord dysfunction, which resolved except for one case (0.17%). Fifty-nine patients (10.1%) developed hypocalcemia, but only three cases (0.51%) became permanent. Only one patient required readmission. In conclusion, MIVAT results in short operative times, minimal blood loss, and few complications and is safely performed in an academic institution.

Abstract BACKGROUND: The minimally invasive lateral retroperitoneal approach for lumbar fusions is a novel technique with good results, but also with significant sensory and motor complications. OBJECTIVE: To present the early results of a modified surgical technique, in which the psoas muscle is dissected under direct visualization. METHODS: Thirteen consecutive patients with L4-5 or L3-4 pathology were prospectively followed after being treated using a minimally invasive lateral approach with direct exposure of the psoas muscle before dissection. There were 7 woman and 6 men with a mean age of 52.3 years. Perioperative parameters like operative time, estimated blood loss, and length of stay, were noted. Pain, paresthesia, and motor weakness, as well as any other complications, were evaluated at 2 weeks and 3 months postoperatively. RESULTS: The mean operative time, estimated blood loss, and length of stay were 163 minutes, 126 mL, and 3 days, respectively. One patient exhibited anterior thigh pain and paresthesia at 2 weeks, both of which resolved by 3 months. Two patients experienced superficial wound infections that healed with antibiotics. The genitofemoral nerve was identified and protected in 7 patients; in 4 patients, it had a more posterior anatomic location than expected. The femoral nerve was not exposed or detected in the operative field by neuromonitoring, nor were there any symptoms related to a femoral nerve injury in any patient. CONCLUSION: Dissection of the psoas muscle under direct visualization during the minimally invasive lateral approach may provide increased safety to the genitofemoral and femoral nerves.

Introduction Laparoscopic liver resection (LLR) in obese patients has been reported to be particularly challenging owing to technical difficulties and various comorbidities. Methods The safety and efficacy outcomes in 314 patients who underwent laparoscopic or open nonanatomical liver resection for colorectal liver metastases (CRLM) were analyzed retrospectively with respect to the patients’ body mass index (BMI) and visceral fat area (VFA). Results Two hundred and four patients underwent LLR, and 110 patients underwent open liver resection (OLR). The rate of conversion from LLR to OLR was 4.4%, with no significant difference between the BMI and VFA groups ( P = .647 and .136, respectively). In addition, there were no significant differences in terms of operative time and estimated blood loss in LLR ( P = .226 and .368; .772 and .489, respectively). The incidence of Clavien-Dindo grade IIIa or higher complications was not significantly different between the BMI and VFA groups of LLR ( P = .877 and .726, respectively). In obese patients, the operative time and estimated blood loss were significantly shorter and lower, respectively, in LLR than in OLR ( P = .003 and < .001; < .001 and < .001, respectively). There was a significant difference in the incidence of postoperative complications, organ/space surgical site infections, and postoperative bile leakage between the LLR and OLR groups ( P = .017, < .001, and < .001, respectively). Conclusion LLR for obese patients with CRLM can be performed safely using various surgical devices with no major difference in outcomes compared to those in nonobese patients. Moreover, LLR has better safety outcomes than OLR in obese patients.

Spinal metastases compressing the spinal cord are a medical emergency and should be operated on if possible; however, patients’ medical condition is often poor and surgical complications are common. Minimizing surgical extant, operative time, and blood loss can potentially reduce postoperative complications. This is a retrospective study describing the patients operated on in our department utilizing a minimally invasive surgery (MIS) approach to decompress and instrument the spine from November 2013 to November 2014. Five patients were operated on for thoracic or lumbar metastases. In all cases a unilateral decompression with expandable tubular retractor was followed by instrumentation of one level above and below the index level and additional screw at the index level contralateral to the decompression side. Cannulated fenestrated screws were used (Longitude FNS) and cement was injected to increase pullout resistance. Mean operative time was 134 minutes and estimated blood loss was minimal in all cases. Improvement was noticeable in neurological status, function, and pain scores. No complications were observed. Technological improvements in spinal instruments facilitate shorter and safer surgeries in oncologic patient population and thus reduce the complication rate. These technologies improve patients’ quality of life and enable the treatment of patients with comorbidities.

ABSTRACT The number of fixed segments in the surgical treatment of thoracolumbar burst fractures remains controversial. This study aims to compare the results of short and long fixation in thoracolumbar burst fractures through a meta-analysis of studies published recently. MEDLINE and Cochrane databases were used. Randomized controlled trials and non-randomized comparative studies (prospective and retrospective) were selected. Data were analyzed with the software Review Manager. There was no statistically significant difference in the Cobb angle of preoperative kyphosis. Long fixation showed lower average measurements postoperatively (MD = 1.41; CI = 0.73-2.08; p<0.0001) and in the last follow-up (MD = 3.98; CI = 3.22-4.75; p<0.00001). The short fixation showed the highest failure rates (RD = 4.03; CI = 1.33-12.16; p=0.01) and increased loss of height of the vertebral body (MD = 1.24; CI = 0.49-1.98; p=0.001), with shorter operative time (MD = -24.54; CI = -30.16 - -18.91; p<0.00001). There was no significant difference in blood loss and clinical outcomes. The high rates of kyphosis correction loss with short fixation and the lower correction rate in the immediate postoperative period were validated. There was no significant difference in the blood loss rates because arthrodesis was performed in a short segment in the analyzed studies. The short fixation was performed in a shorter operative time, as expected. No study has shown superior clinical outcomes. The short fixation had worse rates of kyphosis correction in the immediate postoperative period, and increased loss of correction in long-term follow-up, making the long fixation an effective option in the management of this type of fracture.

Safe thyroid surgery requires meticulous hemostasis. The objective of the current study is to compare the effectiveness and safety of ultrasonic dissection (UD) and electronic vessel sealing (EVS) in patients undergoing thyroidectomy. A retrospective analysis of a prospectively maintained database was performed. Between January 1, 2007 and January 25, 2008, hemostasis was achieved using EVS (LigaSure Precise, Valleylab, Boulder, CO). Since January 25, 2008, hemostasis has been achieved using UD (Harmonic Focus, Ethicon Endo-Surgery, Cincinnati, OH). Operative time, estimated blood loss, gland weight, and postoperative complications were compared. Differences were analyzed using unpaired t test and Chi square with significance assigned P < 0.05. Seventy-four patients underwent total thyroidectomy (EVS n = 59, UD n = 15). Operative time (EVS 115.0 ± 38.3 min, UD 88.0 ± 14.0 min, P = 0.012) was significantly decreased in the UD group compared with the EVS group. There were no significant differences in mean age (EVS 50.4 ± 13.9 years, UD 49.1 ± 15.6 years), gender distribution (EVS 78% female, UD 87% female), estimated blood loss (EVS 49.4 ± 44.7 mL, UD 47.0 ± 70.4 mL), and gland weight (EVS 67.4 ± 66.4 gm, UD 41.3 ± 26.6 gm). Analysis of complications, including hematoma, hypocalcemia, and recurrent laryngeal nerve palsy showed no significant difference. Based on the current analysis, ultrasonic dissection is a safe method of hemostasis for thyroid surgery. Its use decreases operative time when compared with electronic vessel sealing.

Good outcome has been reported with the laparoscopic approach in uncomplicated appendicitis, but a higher incidence of postoperative intraabdominal abscesses has been reported after laparoscopic appendectomy in complicated appendicitis. This retrospective comparative study compares outcome after laparoscopic (LA) and open appendectomy (OA) in complicated appendicitis. All patients who had LA or OA for complicated appendicitis between January 2003 and February 2006 were included in the study. Data collection included demographics, operative time, estimated blood loss, length of stay (LOS), complications, readmission, and reoperative rates. The primary end points for analysis were postoperative intraabdominal abscess and complication rates and secondary end points were LOS and operative time. All data were analyzed on an intent-to-treat basis. Of 104 patients, 43 patients underwent LA and 61 had OA. The mean age (24.8 ± 16.5 versus 31.3 ± 18.9, P = 0.08) in the LA group was lower than the OA group because there was a significantly higher proportion of pediatric patients (34.8% versus 14.8%, P = 0.02) who had LA. There was no significant difference in gender (female/male, 14/29 versus 27/34, P = 0.3) or American Society of Anesthesiologists class distribution (American Society of Anesthesiologists 1/2/3/4/, 35/7/1/0 versus 45/12/3/1, P = 0.68) between the two groups. The operative time (100.5 ± 36.2 versus 81.5 ± 29.5 minutes, P = 0.03) was significantly longer and the estimated blood loss (21 mL versus 33 mL, P = 0.01) was lower in LA when compared with OA, but there was no significant difference in the number of patients with preoperative peritonitis versus abscesses (7/36 versus 13/48, P = 0.6) in both groups. There was no difference in the median LOS (6 [interquartile range 5–9] versus 6 [interquartile range 4–8], P = 0.7) in the two groups. The conversion rate in LA was 18.6% (n = 8). There was also no significant difference in the complication (17/43 [39.5%] versus 21/61 [34.4%], P = 0.54), reoperative (3/43 [7%] versus 0/61 [0%], P = 0.07), and 30-day readmission (5/41 [11.6%] versus 3/61 [4.9%], P = 0.23) rates between the two groups. The rate of postoperative intraabdominal abscesses was significantly higher in the LA group when compared with the OA group (6/43 [14%] versus 0/61 [0%], P = 0.04) and the wound infection (1/43 [2.3%] versus 5/61 [8.2%], P = 0.4) and pulmonary complication (0/43 [0%] versus 3/61 [4.9%], P = 0.26) rate was higher in the OA group. There was no mortality in the LA group, but there was one mortality in the OA group resulting from postoperative myocardial infarction. Laparoscopic appendectomy can be performed in patients with complicated appendicitis with a comparative operative time, LOS, and complication rates but results in a significantly higher intraabdominal abscess rate and lower wound infection rate when compared with OA.
