Association between preoperative lactate level and early complications after surgery for isolated extremity fracture. BMC Musculoskelet Disord 2024; 25:314. [PMID: 38654188 PMCID: PMC11036590 DOI: 10.1186/s12891-024-07409-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 04/02/2024] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND The role of lactate level in selecting the timing of definitive surgery for isolated extremity fracture remains unclear. Therefore, we aimed to elucidate the use of preoperative lactate level for predicting early postoperative complications. METHODS This was a single-center retrospective observational study of patients with isolated extremity fracture who underwent orthopedic surgery. Patients who underwent lactate level assessment within 24 h prior to surgery were included. The incidence of early postoperative complications was compared between patients with a preoperative lactate level of ≥ 2 and < 2 mmol/L. Moreover, subgroup analyses were performed based on the time from hospital arrival to surgery and fracture type. RESULTS In total, 187 patients were included in the study. The incidence of postoperative complications was significantly higher in patients with a preoperative lactate level of ≥ 2 mmol/L than those with a preoperative lactate level of < 2 mmol/L. This result did not change after adjusting for age and severity. Further, a high preoperative lactate level was associated with a greater incidence of postoperative complications in patients who underwent definitive surgery within 6 h after arrival. CONCLUSION A preoperative lactate level of ≥ 2 mmol/L was associated with a greater incidence of early postoperative complications in isolated extremity fractures. Nevertheless, this correlation was only observed among patients who underwent definitive fixation within 6 h after hospital arrival.

Is Routine Post-operative Biological Laboratory Assessment Necessary After Sleeve Gastrectomy? Obes Surg 2024; 34:707-715. [PMID: 38273145 DOI: 10.1007/s11695-024-07065-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 01/17/2024] [Accepted: 01/18/2024] [Indexed: 01/27/2024]
Abstract
BACKGROUND Incidence of post-operative complications after sleeve gastrectomy (SG) is low. However, the early identification of these complications remains crucial. Here, we report the impact of routine laboratory monitoring for the early diagnosis of complications after SG. MATERIAL AND METHODS From January 2018 to December 2019, all consecutive patients who underwent primary SG (n = 457) were included. This was a comparative study of patients undergoing primary SG. Patients were divided into two groups: one group with routine laboratory monitoring performed at postoperative day (POD) 1 and 3 (LAB group) and another group without routine laboratory monitoring (control group). The study's primary endpoint was the overall impact of routine laboratory monitoring. The secondary endpoints were evaluation of patients with complications. RESULTS The population in the two groups were similar in term of demographic and intra-operative data. There was a statistical difference between the two groups in term of length of stay (5.7 days in the LAB group and 3.5 days in the control group (p < 0.001)). There were 19 complications (6.0%) in the LAB group and 5 complications in the control group (3.5%) (p = 0.25). A cut-off C-reactive protein level of 46.3 mg/l was found to be significant (p = 0.006). In the LAB group, 9 patients (2.9%) required readmission vs. three patients (2.0%) in the control group (p = 0.62). CONCLUSION The interest of routine laboratory monitoring after SG seems limited. Routine laboratory monitoring alone is not associated with earlier diagnosis of complications. This routine monitoring is associated with an increase of stay in hospital.

Post-operative complications of total knee arthroplasty in patients with hypertension. INTERNATIONAL ORTHOPAEDICS 2023; 47:701-709. [PMID: 36576519 DOI: 10.1007/s00264-022-05668-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Accepted: 12/14/2022] [Indexed: 12/29/2022]
Abstract
BACKGROUND Hypertension is one of the most common comorbidities among patients undergoing surgery. However, few studies have focused on patients undergoing knee arthroplasty, and most of them had small sample sizes. This study aimed to analyze post-operative complications associated with hypertension in patients who underwent knee replacement surgery. METHODS Data from the 2019 National Inpatient Sample (NIS) database were used. Patients who underwent primary total knee arthroplasty (pTKA) and those who underwent aseptic revision total knee arthroplasty (rTKA) were analyzed separately. Propensity score matching was performed to reduce the effects of demographic factors and comorbidities other than hypertension on post-operative complications. A multinomial logistic regression that included all significantly different demographics and comorbidities was performed to verify the results and evaluate the odds ratios. RESULTS A total of 107,981 patients who underwent pTKA and 6571 who underwent rTKA owing to mechanical complications were identified in the 2019 NIS database. Compared with the non-hypertension group, patients with hypertension had a higher risk of developing acute renal failure and electrolyte disorders after TKA. Further analysis revealed that hyponatraemia and hypokalaemia were associated with hypertension. CONCLUSIONS Hypertension was associated with the incidence of acute renal failure after TKA. It is important to identify patients with risk factors for acute renal failure (in addition to hypertension) and take careful measures to prevent acute renal failure in them.

Radiological assessment and surgical management of cervical spine involvement in patients with rheumatoid arthritis. Rheumatol Int 2023; 43:195-208. [PMID: 36378323 PMCID: PMC9898347 DOI: 10.1007/s00296-022-05239-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Accepted: 10/21/2022] [Indexed: 11/16/2022]
Abstract
The purpose of the present systematic review was to describe the diagnostic evaluation of rheumatoid arthritis in the cervical spine to provide a better understanding of the indications and options of surgical intervention. We performed a literature review of Pub-med, Embase, and Scopus database. Upon implementing specific inclusion and exclusion criteria, all eligible articles were identified. A total of 1878 patients with Rheumatoid Arthritis (RA) were evaluated for cervical spine involvement with plain radiographs. Atlantoaxial subluxation (AAS) ranged from 16.4 to 95.7% in plain radiographs while sub-axial subluxation ranged from 10 to 43.6% of cases. Anterior atlantodental interval (AADI) was found to between 2.5 mm and 4.61 mm in neutral and flexion position respectively, while Posterior Atlantodental Interval (PADI) was between 20.4 and 24.92 mm. 660 patients with RA had undergone an MRI. A pannus diagnosis ranged from 13.33 to 85.36% while spinal cord compression was reported in 0-13% of cases. When it comes to surgical outcomes, Atlanto-axial joint (AAJ) fusion success rates ranged from 45.16 to 100% of cases. Furthermore, the incidence of postoperative subluxation ranged from 0 to 77.7%. With regards to AADI it is evident that its value decreased in all studies. Furthermore, an improvement in Ranawat classification was variable between studies with a report improvement frequency by at least one class ranging from 0 to 54.5%. In conclusion, through careful radiographic and clinical evaluation, cervical spine involvement in patients with RA can be detected. Surgery is a valuable option for these patients and can lead to improvement in their symptoms.

Postoperative lymphocyst formation after pelvic lymphadenectomy for gynecologic cancers: comparison between laparoscopy and laparotomy. Int J Clin Oncol 2022; 27:602-608. [PMID: 35119580 DOI: 10.1007/s10147-021-02052-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Accepted: 10/08/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE The goal of this study was to evaluate, using definitive diagnostic criteria, the incidence of lymphocyst formation following pelvic lymphadenectomy for gynecological cancer, and to compare rates between the approaches of laparoscopy and laparotomy. METHODS We retrospectively reviewed the medical records of all patients who underwent pelvic lymphadenectomy for cervical or endometrial cancer between March of 2010 and March of 2016. We defined a lymphocyst as a circumscribed collection of fluid within the pelvic cavity, with a diameter of 2 cm or more, as diagnosed with ultrasound or computed tomography. RESULTS During the six-year observational period, a pelvic lymphadenectomy was conducted in 196 women with clinical stage I uterine cancer; 90 cases underwent laparoscopy, 106 underwent laparotomy. The minimally invasive laparoscopic group had a lower estimated blood loss (p < 0.01), shorter hospital stay (p < 0.01). Lymphocysts were observed in 14.4% (13/90) of the laparoscopy cases, and in 15.1% (16/106) of the laparotomy cases which means no significant difference of lymphocyst (p = 1.00). The median size of symptomatic lymphocyst was significantly larger in laparotomy group than in laparoscopy group (4.8 cm v.s. 2.8 cm, median) (p = 0.04). Symptomatic lymphocysts were more common in laparotomy [7/90 (7.8%) vs 14/106 (13.2%) (p = 0.253)]. CONCLUSIONS In a retrospective analysis with a strict diagnostic criteria, we could find no statistical difference in lymphocyst occurrence between laparoscopy and laparotomy. The median size of the lymphocyst was bigger and lymphocyst was likely to be symptomatic in the laparotomy group.

Analysis of prognostic factors for postoperative complications and reinterventions after open surgical repair and endovascular aneurysm repair in patients with abdominal aortic aneurysm. Ann Vasc Surg 2021; 77:172-181. [PMID: 34416285 DOI: 10.1016/j.avsg.2021.05.018] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 04/28/2021] [Accepted: 05/05/2021] [Indexed: 12/20/2022]
Abstract
OBJECTIVE A definitive treatment for patients with abdominal aortic aneurysm considering age and comorbidities has not been identified. In the present study, we retrospectively validated treatment outcomes in Japanese patients and proposed the treatment strategy of open surgical repair (OSR) and endovascular aneurysm repair (EVAR). METHODS We retrospectively analyzed data for patients undergoing EVAR or OSR between 2006 and 2017. Patients with ruptured abdominal aortic aneurysm were excluded. We examined post-operative complications, operative mortality, re-intervention and prognosis. RESULTS Throughout the study period, 405 patients underwent EVAR and 176 patients underwent OSR. The percentage of patients with post-operative complications was 35.8% in the OSR group, compared with 13.1% in the EVAR group (P < 0.01). The operative mortality rate was 0.49% in the EVAR group and 0.57% in the OSR group (P = 1.00). With a multivariate analysis, age, hemodialysis, modified Frailty Index (mFI), and OSR were risk factors for post-operative complications. The 5-year re-intervention free survival rate was 63.0 % with hostile neck EVAR compared with 83.1 % with favorable neck EVAR and 86.1 % with OSR group (P < 0.01). With a multivariate analysis, hemodialysis, mFI, and hostile neck EVAR were risk factors for re-intervention. The 5-year overall survival rate was 51.9 % with hostile neck EVAR compared with 73.2 % with favorable neck EVAR and 79.0 % with OSR group (P < 0.01). With a multivariate analysis, age, mFI, and hostile neck EVAR were poor prognostic factors. CONCLUSION Age, mFI, hemodialysis and hostile neck anatomy are useful predictors of post-operative complications, re-intervention and overall survival, and could be useful for informing treatment selection between OSR and EVAR.

Classifying the causes of morbidity and error following treatment of facial fractures. Br J Oral Maxillofac Surg 2021; 60:308-312. [PMID: 34753656 DOI: 10.1016/j.bjoms.2021.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2021] [Accepted: 07/04/2021] [Indexed: 11/23/2022]
Abstract
Analysing morbidity and using this to improve the quality of patient care is an important component of clinical governance. Several methods of data collection and clinical analysis have been suggested, but to date none have been widely adopted. All adult patients sustaining facial fractures were prospectively identified between 01 March 2019 and 28 February 2020, and matched to those who required a return to theatre for surgical complications. Morbidity resulting in a return to theatre was determined using the Clavien-Dindo classification and the Northwestern University error ascribing method. During this period, return to theatre occurred for 33/285 (11.6%) procedures and 23/173 (13.3%) of patients being treated for facial fractures. According to the 27 procedures discussed, Clavien-Dindo Grade IIIb was most commonly found (20/27). Error in judgement (13/35) and nature of disease (12/35) were ascribed as the most common causes of error. Presence of a consultant was associated with increased odds of a return to theatre (p = 0.014). Standardised national data collection of morbidity and error is required for comparisons of outcomes within a single institution or between institutions. To the best of our knowledge, this is the first paper to utilise these widely used methods of morbidity analysis for facial fracture surgery. We would recommend further development of an error analysis method that is more specific to complications from facial fracture surgery.

Limb Graft Occlusion Following Endovascular Aneurysm Repair for Infrarenal Abdominal Aortic Aneurysm with the Zenith Alpha, Excluder, and Endurant Devices: a Multicentre Cohort Study. Eur J Vasc Endovasc Surg 2021; 62:532-539. [PMID: 34266764 DOI: 10.1016/j.ejvs.2021.05.015] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2020] [Revised: 03/26/2021] [Accepted: 05/08/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE Limb graft occlusion (LGO) is a serious complication after endovascular aneurysm repair (EVAR) and while device development enables treatment of increasingly complex aortic anatomy, little is known about how endograft type affects the risk of occlusion. This observational study aimed to explore the incidence of LGO after EVAR for three major endograft systems. METHODS All patients with standard EVAR as the primary intervention for infrarenal abdominal aortic aneurysm (AAA), between January 2012 and December 2018, at five Swedish vascular surgery centres, were included in this multicentre retrospective cohort study. LGO was defined as a total limb occlusion regardless of symptoms, or a treated significant stenosis. A nested case control (NCC) design with incidence density sampling of 1:3 was used for analysis of potential per-operative and morphological risk factors. Conditional logistic regression was used to estimate multivariable odds ratios (OR) with 95% confidence intervals (CI) RESULTS: A total of 924 patients were included. The majority were male (84%), the mean age was 76 years (± 7.5 SD), and median AAA diameter was 59 mm (IQR 55, 67). Patients were treated with Zenith Alpha (n = 315, ZISL limbs), Excluder (n = 152, PLC/PXC limbs), and Endurant (n = 457, ETLW/ ETEW limbs). During median follow up of 37 months (IQR 21, 62), 55 occlusions occurred (5.9%); 39 with Zenith Alpha (12.4%), one with Excluder (0.7%), and 15 with Endurant (3.3%). In the NCC analysis, the Zenith Alpha device (OR 5.31, 95% CI 1.97 - 14.3), external iliac artery (EIA) landing (OR 5.91, 95% CI 1.30 - 26.7), and EIA diameter < 10 mm (OR 4.99, 95% CI 1.46 - 16.9) were associated with an increased risk of LGO. CONCLUSION Endograft device type is an independent risk factor for LGO after EVAR. Specifically, the Zenith Alpha demonstrated an increased risk of LGO compared with the Endurant and Excluder devices. In addition, a narrow EIA and landing zone in EIA are also risk factors for LGO.

A Systematic Review and Narrative Synthesis of Risk Prediction Tools Used to Estimate Mortality, Morbidity, and Other Outcomes Following Major Lower Limb Amputation. Eur J Vasc Endovasc Surg 2021; 62:127-135. [PMID: 33903018 DOI: 10.1016/j.ejvs.2021.02.038] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 02/14/2021] [Accepted: 02/20/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE The decision to undertake a major lower limb amputation can be complex. This review evaluates the performance of risk prediction tools in estimating mortality, morbidity, and other outcomes following amputation. METHODS A systematic review was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The MEDLINE, Embase, and Cochrane databases were searched to identify studies reporting on risk prediction tools that predict outcomes following amputation. Outcome measures included the accuracy of the risk tool in predicting a range of post-operative complications, including mortality (both short and long term), peri-operative morbidity, need for re-amputation, and ambulation success. A narrative synthesis was performed in accordance with the Guidance on the Conduct of Narrative Synthesis In Systematic Reviews. RESULTS The search identified 518 database records. Twelve observational studies, evaluating 13 risk prediction tools in a total cohort of 61 099 amputations, were included. One study performed external validation of an existing risk prediction tool, while all other studies developed novel tools or modified pre-existing generic calculators. Two studies conducted external validation of the novel/modified tools. Nine tools provided risk estimations for mortality, two tools provided predictions for post-operative morbidity, two for likelihood of ambulation, and one for re-amputation to the same or higher level. Most mortality prediction tools demonstrated acceptable discrimination performance with C statistic values ranging from 0.65 to 0.81. Tools estimating the risk of post-operative complications (0.65 - 0.74) and necessity for re-amputation (0.72) also performed acceptably. The Blatchford Allman Russell tool demonstrated outstanding discrimination for predicting functional mobility outcomes post-amputation (0.94). Overall, most studies were at high risk of bias with poor external validity. CONCLUSION This review identified several risk prediction tools that demonstrate acceptable to outstanding discrimination for objectively predicting an array of important post-operative outcomes. However, the methodological quality of some studies was poor, external validation studies are generally lacking, and there are no tools predicting other important outcomes, especially quality of life.

Predictive value of 4th post-operative-day CRP in the early detection of complications after laparoscopic bowel resection for endometriosis. J Gynecol Obstet Hum Reprod 2021; 50:102148. [PMID: 33872816 DOI: 10.1016/j.jogoh.2021.102148] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 03/23/2021] [Accepted: 04/15/2021] [Indexed: 01/20/2023]
Abstract
OBJECTIVE Post-operative CRP on postoperative day 4 (POD) is used for the early detection of complications after colorectal surgery for cancer, but there is no evidence yet that justifies the use of this marker for bowel resection in case of endometriosis. STUDY DESIGN We retrospectively included 66 consecutive patients who underwent bowel resection for endometriosis (stage 4) in Lille university hospital, France, from August 1, 2015 until January 31, 2017. The composite endpoint of our study included anastomotic leakages, infectious or thrombo-embolic complications, hematomas, bowel stenosis, rectorrhagia, voiding dysfunction, and rehospitalization for related symptoms. RESULTS CRP on POD 4 presents a satisfying area under the curve of 0.85, for the composite endpoint. A CRP cut off value of 56 mg/L yielded a sensitivity of 0.61 (IC95%: 0.36 to 0.83) and a specificity of 0.98 (IC95%: 0.89 to 1). The negative and positive predictive values were 0.87 and 0.92. CONCLUSION The negative predictive value of the CRP on POD 4 after bowel resection for endometriosis is a useful early indicator for detecting a complication. Therefore, this biomarker might be safely used as an additional criterion for a safe discharge from hospital after colorectal resection in endometriosis.

Challenging proximal hypospadias repairs: An evolution of technique for two stage repairs. J Pediatr Urol 2021; 17:225.e1-225.e8.

Abstract
INTRODUCTION Proximal hypospadias repair remains challenging. Our approach to the first stage of two-stage proximal hypospadias repairs has evolved from using Byars' flaps to preputial inlay grafts in anatomically suitable cases and pedicled preputial flaps in more complex repairs. We reviewed our outcomes, hypothesizing that inlay grafts and pedicled preputial flaps were associated with lower complication risks than Byars' flaps. STUDY DESIGN A single institution, retrospective, cohort study of consecutive two-stage, primary, proximal hypospadias repairs performed from 2007 to 2017 was conducted. Patients with <6 months follow-up and incomplete operative reports were excluded. Risk of complications (fistula, dehiscence, diverticulum, meatal stenosis, stricture) were evaluated following urethroplasty and stratified by first-stage repair technique. As technique refinements have been made since 2012, comparisons between two temporal subgroups (those who underwent repair in 2007-2012 and in 2013-2017) were made. RESULTS 78 of 127 patients met inclusion criteria. Overall complication rate was 47% (Summary Table). Median follow-up was 25.4 months (range 6.4-128.5 months) after urethroplasty. Pedicled preputial flaps (hazards ratio [HR] 0.30; 95% Confidence Interval [CI] 0.14-0.65) and inlay grafts (HR 0.32; 95% CI 0.11-0.95) were associated with lower complication risks compared to Byars' flaps (Summary Table). Median time to complication was significantly shorter for Byars' flaps (5.7 months) than for inlay grafts (40.6 months) and pedicled preputial flaps (79.2 months) by Kaplan Meier analysis. Temporal subgroup comparisons showed that overall complication rates decreased from 70% to 31% (p = 0.001), but differences in complication rates by first-stage technique were not statistically significant. DISCUSSION In our cohort, repairs with Byars' flaps had the highest complication rate, which is consistent with our observations that urethras tubularized from Byars' flaps lack appropriate backing and are hypermobile and irregular. To overcome these shortcomings, modifications were made to our approach to two-stage proximal hypospadias repairs with the use of inlay grafts and pedicled preputial flaps quilted to the underlying corporal bodies to optimize the stability of the urethral plate. Our preliminary results are promising. CONCLUSION Approach to the first stage of two-stage repairs affects outcomes. Pedicled preputial flaps and inlay grafts were associated with lower complication risks than Byars' flaps. Refinement of technique and patient selection may have resulted in fewer complications in the short term. However, long-term follow-up is needed.

Missed positional gluteal compartment syndrome in an obese patient after foot surgery: a case report. Patient Saf Surg 2020; 14:35. [PMID: 32973924 PMCID: PMC7493869 DOI: 10.1186/s13037-020-00260-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Accepted: 09/08/2020] [Indexed: 11/13/2022] Open
Abstract
Background Gluteal compartment syndrome is an uncommon condition and can be difficult to diagnose. It has been diagnosed after trauma, vascular injury, infection, surgical positioning, and prolonged immobilization from drug or alcohol intoxication. The diagnosis is based on clinical findings and, in most cases, recognizing these symptoms and making a diagnosis early is critical to a complete recovery. Case presentation A 53-year-old male who underwent left foot surgery had severe pain to his contralateral hip and posterior gluteal compartment radiating to the right lower extremity immediately postoperative. He was positioned supine with a “bump” placed under his right hip to externally rotate his operative leg during the surgery. Due to the patient’s complex past medical history, a presumptive diagnosis of a herniated disc and/or compression of the sciatic nerve was made as a cause for the patient’s pain. This resulted in a misdiagnosis period of 36 h until the patient was diagnosed with unilateral gluteal compartment syndrome. Performing a fasciotomy was decided against due to the increased risk of complications. The patient was treated with administration of IV fluids and closely monitored. On post-op day 6, the patient was discharged. At three months post-op, the patient was walking without a limp and he had no changes in his peripheral neurologic examination compared to his preoperative baseline. Conclusion Gluteal compartment syndrome is a surgical emergency that must be considered postoperatively especially in obese patients with prolonged operation times who experience acute buttock pain. The use of positional bars or “bumps” in the gluteal area should be used with caution and raise awareness of this complication after orthopedic surgeries.

Acute normovolemic hemodilution reduced allogeneic blood transfusion without increasing perioperative complications in patients undergoing free-flap reconstruction of the head and neck. J Anesth 2019; 34:187-194. [PMID: 31768720 PMCID: PMC7223952 DOI: 10.1007/s00540-019-02714-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Accepted: 11/14/2019] [Indexed: 01/25/2023]
Abstract
Purpose The present case–control study was conducted to evaluate whether acute normovolemic hemodilution (ANH) can reduce the need for perioperative allogeneic blood transfusion (ABT) and affect the incidence of perioperative complications in free-flap reconstruction of the head and neck. Methods This single-center, retrospective, observational study included the perioperative data of 123 patients who underwent free-flap reconstruction of the head and neck following oncological surgery. Patients were divided into the following two groups according to whether they received ANH: ANH group and non-ANH group. We investigated whether ANH can reduce the need for perioperative ABT using propensity score-adjusted logistic regression analysis. Results Of the 123 patients, 113 patients were assessed; 57 patients were in the ANH group and 56 patients were in the non-ANH group. The rate [ANH group vs. non-ANH group, n (%): 2 (3.5%) vs. 23 (41.1%), p < 0.0001] and amount [median (IQR): 0 mL (0, 0) vs. 0 mL (0, 280), p < 0.0001] of ABT were significantly lower in the ANH group than in the non-ANH group. Propensity score-adjusted multivariate logistic regression analysis indicated that ANH use [odds ratio (OR): 0.040; 95% confidence interval (CI) 0.005, 0.320; p = 0.0024)] was one of the independent predictors of perioperative ABT. There were no significant differences in the incidences of post-operative complications between the two groups. Conclusion ANH use can reduce the need for perioperative ABT in patients undergoing free-flap reconstruction of the head and neck without increasing the incidence of post-operative complications.

Severe Intraoperative Orbital Venous Congestion during Resection of a Frontal Meningioma Presenting with Post-operative Vision Loss and Ophthalmoplegia: A Case Report. Neuroophthalmology 2018; 43:265-268. [PMID: 31528194 DOI: 10.1080/01658107.2018.1527856] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2018] [Revised: 09/01/2018] [Accepted: 09/20/2018] [Indexed: 10/28/2022] Open
Abstract
We describe a unique case of a middle-aged man who noticed complete vision loss in the right eye after awaking from resection of a large right-sided frontal meningioma. Visual acuity was hand motions, and there were multiple signs of right orbital venous congestion. Magnetic resonance imaging and venography (MRI/V) of the brain and orbits demonstrated expected post-operative findings with no evidence of cavernous sinus thrombosis or fistula. Empiric treatment with intravenous antibiotics and intravenous methylprednisolone were ineffective. Immediate post-operative computerised tomography (CT) images were re-reviewed and revealed right restricted diffusion of the entire intraorbital right optic nerve. Discussion with the neurosurgical team revealed that during craniotomy, a prominent diploic venous plexus in the frontal bone adjacent to the meningioma was identified and coagulated with bone wax. Review of pre-operative imaging revealed large diploid flow voids in the right frontal bone, corresponding to the intraoperative findings. This prominent venous plexus appeared to drain from the meningioma posteriorly into the vein of Labbe. A second pathway drained anteriorly through the right angular vein into the orbit. We hypothesise that the posterior outflow pathway was coagulated intraoperatively, causing redirection of all venous outflow from the meningioma into the right orbit through the anterior pathway. This resulted in significant orbital hypertension with manifest signs and symptoms. Furthermore, sudden rise in intraorbital pressure led to infarction of the optic nerve, leaving the patient with hand motions vision. We suggest that pre-operative vascular imaging should be performed in patients with large meningiomas, as pre-operative embolisation of venous outflow channels may prevent severe post-operative complications.

Successful repair using thymus pedicle flap for tracheoesophageal fistula: a case report. Surg Case Rep 2018; 4:49. [PMID: 29796790 PMCID: PMC5966367 DOI: 10.1186/s40792-018-0458-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2018] [Accepted: 05/17/2018] [Indexed: 11/22/2022] Open
Abstract
Background Treatment for tracheoesophageal fistula (TEF), a life-threatening complication after esophagectomy, is challenging. Case presentation A 75-year-old man with thoracic esophageal cancer underwent subtotal esophagectomy and gastric tube reconstruction through the post-mediastinal root after neoadjuvant chemotherapy. Owing to postoperative anastomotic leakage, an abscess formed at the anastomotic region. Sustained inflammation from the abscess caused refractory TEF between the esophagogastric anastomotic site and membrane of the trachea, and several conservative therapies for TEF failed. Hence, the patient underwent surgery including division of the fistula, direct suturing of the leakage sites, and reinforcement with the flap of the thymus pedicle. As a result, the abscess and TEF disappeared after surgery and the patient was immediately administered an oral diet and discharged home 103 days after initial surgery. Conclusions Although pedicle flaps for the reinforcement of TEF are usually obtained from muscle or pericardium, these flaps need enough lengths to overcome moving distance. We are the first in the existing literature to have successfully treated TEF with surgical repair using a thymus flap located close to TEF. The thymus pedicle might be another candidate for the reinforcement flap in TEF.

Lateral trochanteric pain following total hip arthroplasty: radiographic assessment of altered biomechanics as a potential aetiology. Ir J Med Sci 2018; 187:663-668. [PMID: 29335832 DOI: 10.1007/s11845-017-1701-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2017] [Accepted: 10/16/2017] [Indexed: 12/20/2022]
Abstract
INTRODUCTION Lateral trochanteric pain (LTP) complicates up to 17% of cases of total hip arthroplasty (THA). Studies have refuted underlying trochanteric bursitis. Restoration of the femoral offset and reproduction of the natural femoral centre of rotation are important in successful arthroplasty. LTP is believed to be associated with their alteration. AIM The aim of our study was to evaluate the effect of femoral offset and centre of rotation on the incidence of LTP post-THA. METHODS A retrospective case control study was developed from 158 patients who underwent a THA over a two-year period to form two patient cohorts. Twenty-nine patients diagnosed with LTP were matched with 110 control subjects. The direct lateral approach was used in all cases. Anterior-posterior pelvic radiographs before and after surgery were compared to assess the femoral, cup and global offsets and limb length discrepancies between the two groups. Statistical analyses were performed using the Mann-Whitney U test and independent samples t test. RESULTS Twenty-nine diagnosed with post-operative LTP. Sixty-two percent of symptomatic patients were female (p = 0.13). The median ages were 74.33 (symptomatic) and 70.71 (control) (p = 0.11). The differences (pre-post) of the femoral (p = 0.17), cup (p = 0.5) and global offsets (p = 0.99) and mean of limb length discrepancy (LLD) (p = 0.83) were not significant between the two groups. CONCLUSION No relationship was found between LTP and femoral offset or femoral centre of rotation. Disruption of the soft tissues during a lateral approach with resultant abductor tear, tendon defects and tendinitis might play a role in LTP and explain the apparent efficacy of corticosteroid injections.

A case report of an unusual cause of postoperative leg pain after posterior lumbar fusion. Ann Med Surg (Lond) 2017; 19:29-32. [PMID: 28616222 PMCID: PMC5458057 DOI: 10.1016/j.amsu.2017.05.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2017] [Revised: 05/19/2017] [Accepted: 05/20/2017] [Indexed: 11/28/2022] Open
Abstract
We report the case of a 36-year old man who underwent elective posterior lumbar spinal fusion after presenting with bilateral leg pain with associated back pain. He had undergone a L5/S1 discectomy in 2001, which provided good symptomatic relief. On this admission, he underwent elective L4-S1 posterolateral fusion and bilateral L4/5 and L5/S1 decompression. Intra-operatively a pedicle screw had to be re-inserted after fluoroscopy confirmed a lateral breech. The patient had no major postoperative complications until the sixth day when the patient re-presented with acute leg pain and weakness. Following a local multidisciplinary meeting (MDT) an MRI showed a large haematoma at the right psoas muscle. CT angiogram confirmed a bleeding lumbar segmental vessel at the site of the previous misplaced screw and an emergency fluoroscopic guided embolisation of the vessel was performed. The patient recovered well post operatively and was discharged back to the community 12 days later. Haemorrhage, as in this case a psoas haematoma should be considered as one of the differentials in patients with recurrent post-operative radiculopathy following posterior lumbar spine fusion. This should be suspected particularly if there has been a misplacement of one or more screws as this can cause injury to blood vessels and be fatal for the patient.

Abstract
Autologous microsurgical flap reconstruction has become commonplace in most plastic surgery units, and the success rates of this procedure have markedly increased over recent years. However, the possibility of flap failure still needs to be considered. A review of the literature reveals that the critical period for flap-threatening complications is the first 24-48 post-operative hours; however, the window for the onset of these complications remains open for up to 7 days post-operatively. In this study, we focus on the timing of flap complications, aiming to elucidate the time period over which meticulous flap monitoring can positively contribute to flap salvage rates. The relevant literature on the study topic was collated and reviewed in conjunction with the senior author's case series, which consisted of a total of 335 free flaps used during a 2-year period for breast and head and neck reconstruction or limb trauma. Patients' series were then divided into groups according to the complications timing. The correlation between the timing of complications and the flap salvage rate was investigated among the groups. Overall analysis of both the literature and our own data on 335 free flaps showed a progressive reduction in flap salvage rate during post-operative days; the correlations between the times of complication onset and the flap salvage rates in all groups were significant up to the third post-operative day. The correlations between salvage rates and later complications were not significant. Our results suggest that hourly flap monitoring should be compulsory during the first 48 post-operative hours, but clinical monitoring four times daily should be sufficient thereafter.

Risk Factors for Post-operative Complications in Primary Oral Cancer Surgery-a Prospective Study. Indian J Surg Oncol 2017; 9:28-34.

Abstract
The surgical treatment of oral cavity cancers can be influenced by post-operative complications. Identification of risk factors based on clinical characteristics may assist in therapeutic planning and thereby helps in reducing complications. Here, an attempt is made to identify the factors associated with post-operative complications (complications developing within 1 month of surgery) in patients undergoing primary oral cancer surgery. Six hundred seventy-six consecutive patients who underwent primary surgery for oral cancer from December 2007 to May 2010 were prospectively evaluated. The risk factors that predict for post-operative complications were analyzed. There was one mortality and 15% (103 patients) had post-operative complications. The complications included metabolic complications, primary site problems, donor site problems, and systemic complications. Fifteen factors were found statistically significant for the development of post-operative complications by univariate analysis. On multivariate analysis, three of the 15 factors, i.e., presence of COPD, full thickness wide excision, and increased duration of surgery were found to be independently associated with the development of post-operative complications. Presence of COPD, full thickness wide excision, and increased duration of surgery were identified as independent risk factors for post-operative complications in primary oral cancer surgery. The development of complications invariably resulted in increased hospital stay. Hence, the prompt recognition of risk factors for complications based on pre-operative clinical characteristics plus the identification of the risks associated with the surgical procedure can help in determining the appropriate therapeutic planning to prevent complications and in achieving cost effectiveness.

Post-operative outcomes after cleft palate repair in syndromic and non-syndromic children: a systematic review protocol. Syst Rev 2017; 6:52. [PMID: 28279195 PMCID: PMC5345151 DOI: 10.1186/s13643-017-0438-2] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2016] [Accepted: 02/17/2017] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND There is a lack of high-level evidence on the surgical management of cleft palate. An appreciation of the differences in the complication rates between different surgical techniques and timing of repair is essential in optimizing cleft palate management. METHOD A comprehensive electronic database search will be conducted on the complication rates associated with cleft palate repair using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. Two independent reviewers with expertise in cleft pathology will screen all appropriate titles, abstracts, and full-text publications prior to deciding whether each meet the predetermined inclusion criteria. The study findings will be tabulated and summarized. The primary outcomes will be the rate of palatal fistula, the incidence and severity of velopharyngeal insufficiency, and the rate of maxillary hypoplasia with different techniques and also the timing of the repair. A meta-analysis will be conducted using a random effects model. DISCUSSION The evidence behind the optimal surgical approach to cleft palate repair is minimal, with no gold standard technique identified to date for a certain type of cleft palate. It is essential to appreciate how the complication rates differ between each surgical technique and each time point of repair, in order to optimize the management of these patients. A more critical evaluation of the outcomes of different cleft palate repair methods may also provide insight into more effective surgical approaches for different types of cleft palates.

Surgical apgar score predicts early complication in transfemoral amputees: Retrospective study of 170 major amputations. World J Orthop 2016; 7:832-838. [PMID: 28032037 PMCID: PMC5155260 DOI: 10.5312/wjo.v7.i12.832] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2016] [Revised: 08/25/2016] [Accepted: 10/27/2016] [Indexed: 02/06/2023] Open
Abstract
AIM To assess whether the surgical apgar score (SAS) is a prognostic tool capable of identifying patients at risk of major complications following lower extremity amputations surgery.
METHODS This was a single-center, retrospective observational cohort study conducted between January 2013 and April 2015. All patients who had either a primary transtibial amputation (TTA) or transfemoral amputation (TFA) conducted at our institution during the study period were assessed for inclusion. All TTA patients underwent a standardized one-stage operative procedure (ad modum Persson amputation) performed approximately 10 cm below the knee joint. All TTA procedures were performed with sagittal flaps. TFA procedures were performed in one stage with amputation approximately 10 cm above the knee joint, performed with anterior/posterior flaps. Trained residents or senior consultants performed the surgical procedures. The SAS is based on intraoperative heart rate, blood pressure and blood loss. Intraoperative parameters of interest were collected by revising electronic health records. The first author of this study calculated the SAS. Data regarding major complications were not revealed to the author until after the calculation of SAS. The SAS results were arranged into four groups (SAS 0-4, SAS 5-6, SAS 7-8 and SAS 9-10). The cohort was then divided into two groups representing low-risk (SAS ≥ 7) and high-risk patients (SAS < 7) using a previously established threshold. The outcome of interest was the occurrence of major complications and death within 30-d of surgery.
RESULTS A logistic regression model with SAS 9-10 as a reference showed a significant linear association between lower SAS and more postoperative complications [all patients: OR = 2.00 (1.33-3.03), P = 0.001]. This effect was pronounced for TFA [OR = 2.61 (1.52-4.47), P < 0.001]. A significant increase was observed for the high-risk group compared to the low-risk group for all patients [OR = 2.80 (1.40-5.61), P = 0.004] and for the TFA sub-group [OR = 3.82 (1.5-9.42), P = 0.004]. The AUC from the models were estimated as follows: All patients = [0.648 (0.562-0.733), P = 0.001], for TFA patients = [0.710 (0.606-0.813), P < 0.001] and for TTA patients = [0.472 (0.383-0.672), P = 0.528]. This indicates moderate discriminatory power of the SAS in predicting postoperative complications among TFA patients.
CONCLUSION SAS provides information regarding the potential development of complications following TFA. The SAS is especially useful when patients are divided into high- and low-risk groups.

Abstract
UNLABELLED OBJECTIVES AND IMPORTANCE: Cochlear implantation is an established, reliable, and safe procedure with a low complication rate. Electrode array extrusion through the posterior aspect of external ear canal is a potential major complication of cochlear implant surgery that may result in revision surgery or explantation. Although there have been previous case reports of such extrusions through the tympanic membrane, this is the first well-documented report of an extrusion through the posterior canal wall which was previously intact. CLINICAL PRESENTATION In this case report, we present a case of electrode array extruding through an initially intact posterior canal wall presenting as a delayed post-operative complication in a 13-year old Asian boy. INTERVENTION With reference to existing relevant literature, the case is discussed focusing on its management, possible contributing factors, and prevention strategies. CONCLUSION Excessive thinning of the bony wall should be avoided as it can potentially break down. Abutment on the posterior canal wall by a coiled electrode array in the mastoid cavity exerting undue pressure on the bony wall can further contribute to additional stress. The implant surgeon must be cognizant of mastoid growth patterns in children. Life-long regular follow-up in implanted patients is crucial.

Abstract
Liver transplantation is a technically complex and long surgical procedure. A large quantity of various materials such as catheters, sutures, needles and clips are frequently used during the procedure. These materials may enter in the liver from the vascular or biliary orifices inadvertently. A 50-year-old patient who had hepatic failure due to HBV underwent a deceased-donor liver transplantation. The deceased donor was a 75-year-old HbsAg(+) man. The recipient had subfebrile fever and leukocytosis post-operatively. A control computed tomography revealed a cuneiform ischemic area, and a foreign body inside the right anterior portal vein branch proximal to this ischemic region. A 10-F Nelaton catheter, 5-cm long, was removed from the portal vein by surgery. Retrospectively, we understood that the portal vein was cut during the back-table procedure and the portal vein catheter was replaced with a larger one for better irrigation. Most probably, the original catheter was cut together with the portal vein, and the tip of the catheter was retained in the portal system and migrated into the liver. As far as we know, such a complication of liver transplantation has never been described previously.

Removal of bicortical screws and other osteosynthesis material that caused symptoms after bilateral sagittal split osteotomy: a retrospective study of 251 patients, and review of published papers. Br J Oral Maxillofac Surg 2014; 52:756-60.

Abstract
Rigid fixation with either bicortical screws or miniplates is the current standard way to stabilise the mandibular segments after bilateral sagittal split osteotomy (BSSO). Both techniques are widely used and the superiority of one or other method is still debatable. One complication of rigid fixation is the need to remove the osteosynthesis material because of associated complaints. The main aim of this retrospective study was to analyse how often we needed to remove bicortical screws because they caused symptoms after BSSO in our clinic. Review of other published papers also enabled us to investigate the reported rates of removal of screws and miniplates at other centres. The mean (SD) duration of follow-up of 251 patients (502 sites) was 432 (172) days, and the number of bicortical screws removed in our clinic was 14/486 sites (3%). Other methods of fixation were used at 16 sites. We found no significant association between removal of bicortical screws and age, sex, presence of third molars, or bad splits. Published rates of removal of bicortical screws and miniplates are 3.1%-7.2% and 6.6%-22.2% per site, respectively. These findings show that fixation with bicortical screws after BSSO is associated with a low rate of removal of osteosynthesis material. Reported incidences imply a lower rate of removal for screws than for miniplates.

Off-pump coronary bypass grafting causing stunned myocardium. J Tehran Heart Cent 2012; 7:143-6.

Abstract
The term "stunned myocardium" refers to abnormalities in the myocardial function following reperfusion and is common in on-pump coronary artery bypass grafting (CABG) and is exceedingly rare in off- pump CABG. A 53-year-old man presented with unstable angina due to the severe stenosis of the left anterior descending coronary artery (LAD) and the obtuse marginal. Laboratory findings and Chest X-ray revealed nothing abnormal. The intraoperative course was uneventful. The patient left the operating room without any inotropic support. Six hours later, however, he developed low cardiac output. At exploration, cardiac tamponade was excluded and flowmetry showed that the graft had adequate function. Cardiac enzymes were normal. High-dose adrenalin and Dobutamine were administrated and an intra-aortic balloon pump was used. After hemodynamic stabilization, the patient left the Intensive Care Unit without an intra-aortic balloon pump and inotropic support. On the fifth postoperative day, coronary angiography showed patent grafts and correct anastomotic sites. On the seventh postoperative day, the akinetic lateral wall of the left ventricle changed to dyskinesia. Finally after hospital discharge on the thirtieth postoperative day, an echocardiogram showed normal left ventricular function without regional wall motion abnormalities.
