Feasibility and operative outcomes of surgery in the liver area in advanced ovarian cancer.

OBJECTIVE: The study aimed to characterize intra-and postoperative complications according to a standardized anatomo-surgical classification for ovarian cancer metastases in the liver area. METHODS: Data from all patients with advanced ovarian cancer undergoing primary or secondary surgery with perihepatic liver involvement (May-2016 to May-2022), were retrospectively retrieved and classified according to a standardized anatomo-surgical classification, and clustered into four Classes: Class I "Peritoneal", Class II "Hepatoceliac-lymph-nodes", Class III "Parenchymal" and Class IV Mixed (≥ 2 classes). RESULTS: Data from 615 patients were collected. Intraoperative complications were observed in 15%, and severe postoperative complications in 17.6% of cases. While surgical complexity scores were similar, Class IV had longer operative times, higher blood loss, and a 30.4% intraoperative transfusion rate. Class II showed a higher prevalence of vascular injuries (8%). Classes II and IV were significantly associated with severe postoperative complications. Specific complications varied among classes, such as perihepatic collection and intrahepatic hematoma/abscess in Class III (p = 0.003, p < 0.001, respectively), and pleuric effusion, sepsis, anemia, and "other complications" in Class IV (p = 0.002, p = 0.004, p = 0.03, p = 0.03, respectively). Multivariable analysis identified Class II and IV (Class II: OR 4.991, p = 0.045; Class IV: OR 5.331, p = 0.030), Surgical Complexity Score group 3 (OR:3.922, p = 0.003), and the presence of residual tumor (OR:1.748, p = 0.048) as independent risk factors for severe postoperative complications. CONCLUSIONS: Liver procedures during advanced ovarian cancer surgery are feasible with acceptable complication rates According to the anatomo-surgical classification, metastatic patterns are related to both different surgical outcomes and postoperative complication profiles.

Impact of patient-reported salpingitis on the outcome of hysterectomy and adnexal surgery: A national register-based cohort study in Sweden.

INTRODUCTION: Salpingitis is caused by ascending microbes from the lower reproductive tract and contributes to tubal factor infertility, ectopic pregnancy, and chronic pelvic pain. The aim of this study was to analyze if the risk for complications and dissatisfaction after hysterectomy and adnexal surgery was increased in women reporting previous salpingitis. MATERIAL AND METHODS: This is an observational cohort study including women undergoing gynecologic surgery from 1997 to 2020, registered in the Swedish National Quality Register of Gynecologic Surgery (GynOp). Patient-reported previous salpingitis was the exposure. Complications up to 8 weeks and satisfaction at 1 year postoperatively were the outcomes. Multivariable logistic regression and ordinal regression were performed. Results were adjusted for potential confounders including age, body mass index, smoking and year of procedure as well as endometriosis and previous abdominal surgery. Multiple imputation was used to handle missing data. RESULTS: In this study, 61 222 women were included, of whom 5636 (9.2%) women reported a previous salpingitis. There was an increased risk for women reporting previous salpingitis in both the unadjusted and fully adjusted models to have complications within 8 weeks of surgery (adjusted odds ratio [aOR] 1.22, 95% confidence interval [CI] 1.14-1.32). The highest odds ratios were found for bowel injury (aOR 1.62, 95% CI 1.29-2.03), bladder injury (aOR 1.52, 95% CI 1.23-1.58), and postoperative pain (aOR 1.37, 95% CI 1.22-1.54). Women exposed to salpingitis were also more likely to report a lower level of satisfaction 1 year after surgery compared with unexposed women (aOR 0.87, 95% CI 0.81-0.92). CONCLUSIONS: Self-reported salpingitis appears to be a risk factor for complications and dissatisfaction after gynecologic surgery. This implies that known previous salpingitis should be included in the risk assessment before gynecologic procedures.

Preoperative OCT lens evaluation in posterior subcapsular cataract - prevention of complications from phacoemulsification.

PURPOSE: To assess the possibility of anterior segment optical coherence tomography (AS-OCT)-based preoperative evaluation of the lens in order to prevent and predict intraoperative complications of posterior subcapsular cataract (PSC) surgery. METHODS: This prospective study included 512 eyes diagnosed with PSC. AS-OCT was performed using Line, Cross Line and 3D Cornea scans to visualize the posterior capsule. The posterior capsule and opacities in the subcortical and cortical lens, their relationship and the state of the retrolenticular space were assessed. The study sample was divided into three groups while taking into account the revealed morphological changes in the lens. Groups 1, 2, and 3 comprised 312, 185 and 15 eyes, respectively, with each group characterized by a specific type (1, 2 or 3) of morphological AS-OCT changes in the PSC. Surgery consisted of ultrasound phacoemulsification with intraocular lens implantation. Well-known measures related to cataract surgery stages were performed, if required, to preserve the integrity of the posterior capsule, while taking into account the type of PSC changes. We preoperatively determined the eyes at risk for intraoperative posterior capsular rupture (PCR) and detection of posterior capsular plaque (PCP), and compared this data with the postoperative data on the state of the posterior capsule. RESULTS: The PSC cases with an expected rate of intraoperative complications of 0 to 10% were classified as those with a low risk, whereas the rest, with a high risk of complications. Only eyes with type 2 or type 3 PSC changes were expected to have a high risk of intraoperative PCP, and only eyes with type 3 PSC changes, a high risk of PCR. In groups 1, 2 and 3, the rates of intraoperative PCP were 0%, 100% and 46.7%, respectively, and the rates of intraoperative PCR, 0%, 0% and 53.3%, respectively. There was a significant positive correlation between preoperative OCT-based morphology of the lens and intraoperative complications (r = 0.88, p ≤0.001). Sensitivity and specificity for the method of AS-OCT-based evaluation of risks of intraoperative complications in PSC surgery were 98.8% and 96.5%, respectively. CONCLUSION: AS-OCT allows evaluating preoperatively posterior lens opacification morphology and posterior capsular changes, determining the risks of complications, and performing surgical planning for PSC. KEY MESSAGES: What is Known? Complications (posterior capsule (PC) rupture with or without vitreous loss and residual PC plaque) are common in, and affect the expected outcome of, posterior subcapsular cataract (PSC) surgery. What is new? PC plaque is most likely in eyes with preoperative type 2 changes in the PSC, whereas eyes with preoperative type 3 changes are likely to show PC rupture or residual PC plaque. AS-OCT enables an experienced surgeon to predict the risks of intraoperative complications in, and perform surgical planning for, PSC surgery.

Lung ultrasound diagnosis of pulmonary edema resulting from excessive fluid absorption during hysteroscopic myomectomy: a case report.

BACKGROUND: Hysteroscopic surgery is a safe procedure used for diagnosing and treating intrauterine lesions, with a low rate of intraoperative complications. However, it is important to be cautious as fluid overload can still occur when performing any hysteroscopic surgical technique. CASE PRESENTATION: In this case report, we present a unique instance where lung ultrasound was utilized to diagnose pulmonary edema in a patient following a hysteroscopic myomectomy procedure. The development of pulmonary edema was attributed to the excessive absorption of fluid during the surgical intervention. By employing lung ultrasound as a diagnostic tool, we were able to promptly identify and address the pulmonary edema. As a result, the patient received timely treatment with no complications. This case highlights the importance of utilizing advanced imaging techniques, such as lung ultrasound, in the perioperative management of patients undergoing hysteroscopic procedures. CONCLUSIONS: This case report underscores the significance of early detection and intervention in preventing complications associated with fluid overload during hysteroscopic myomectomy procedures.

Determinants of Perioperative Complications in Day-Surgery for Endometriosis: A Retrospective Cohort.

OBJECTIVES: Endometriosis is a common gynaecologic disease for which surgery is often required. Our objective was to evaluate the potential determinants of perioperative complications in day-surgeries for endometriosis. METHODS: We conducted a retrospective cohort study of patients undergoing day-surgeries for endometriosis using Canadian administrative data from between 2015 and 2019. A multilevel logistic model with a random intercept at the centre level was created to assess the association between potential determinants, including age, site(s) of endometriosis lesion, centre-volume, surgical intervention, and a composite outcome of complications or specific complications. RESULTS: We observed a higher risk of complications associated with greater age (40-44 vs. 20-24 years, adjusted odds ratio [aOR] 1.58; 95% CI 1.26-1.98); hysterectomies (aOR 2.29; 95% CI 1.73-3.06) compared with minor conservative surgery; lesions of the bowel or urinary tract system (aOR 1.54; 95% CI 1.16-2.06), and extra-pelvic sites of endometriosis (aOR 1.24; 95% CI 1.07-1.52) compared with endometriosis of the uterus; and with comorbidities (aOR 1.59; 95% CI 1.09-2.32). Endometriosis lesions to the bowel and urinary tract system and to extra-pelvic sites (compared with no endometriosis at the site) were associated with a greater risk of accidental damages (aOR 1.84; 95% CI 1.43-2.37) and urinary system complications (aOR 1.75; 95% CI 1.24-2.48), respectively. Among patients undergoing hysterectomies compared with those undergoing minor conservative surgery, infectious complications (aOR 8.56; 95% CI 4.70-15.59) and accidental damages (aOR 2.31; 95% CI 1.70-3.14) were more frequent. CONCLUSIONS: Complications in day-surgeries for endometriosis are more frequent with older age, hysterectomy, comorbidities, and endometriosis of the bowel, urinary tract system, and extra-pelvic locations. More extensive disease is associated with more extensive surgical dissection and a higher risk of complications.

Intraoperative adverse events among surgeons in Singapore: a multicentre cross-sectional study on impact and support.

BACKGROUND: It is known that many surgeons encounter intraoperative adverse events which can result in Second Victim Syndrome (SVS), with significant detriment to their emotional and physical health. There is, however, a paucity of Asian studies in this space. The present study thus aimed to explore the degree to which the experience of an adverse event is common among surgeons in Singapore, as well as its impact, and factors affecting their responses and perceived support systems. METHODS: A self-administered survey was sent to surgeons at four large tertiary hospitals. The 42-item questionnaire used a systematic closed and open approach, to assess: Personal experience with intraoperative adverse events, emotional, psychological and physical impact of these events and perceived support systems. RESULTS: The response rate was 57.5% (n = 196). Most respondents were male (54.8%), between 35 and 44 years old, and holding the senior consultant position. In the past 12 months alone, 68.9% recalled an adverse event. The emotional impact was significant, including sadness (63.1%), guilt (53.1%) and anxiety (45.4%). Speaking to colleagues was the most helpful support source (66.7%) and almost all surgeons did not receive counselling (93.3%), with the majority deeming it unnecessary (72.2%). Notably, 68.1% of the surgeons had positive takeaways, gaining new insight and improving vigilance towards errors. Both gender and surgeon experience did not affect the likelihood of errors and emotional impact, but more experienced surgeons were less likely to have positive takeaways (p = 0.035). Individuals may become advocates for patient safety, while simultaneously championing the cause of psychological support for others. CONCLUSIONS: Intraoperative adverse events are prevalent and its emotional impact is significant, regardless of the surgeon's experience or gender. While colleagues and peer discussions are a pillar of support, healthcare institutions should do more to address the impact and ensuing consequences.

Accuracy of Ultrasound in the Prediction of the FIGO Classification of Placenta Accreta Spectrum.

OBJECTIVES: To evaluate the accuracy of greyscale ultrasound (US) and colour Doppler detecting placenta accreta spectrum (PAS) based on the newly recommended International Federation of Obstetrics and Gynaecology (FIGO) grading system. METHODS: This prospective study was conducted on women diagnosed with placenta previa or low-lying placenta involving the anterior uterine wall and associated with PAS as identified by the US. Transabdominal and transvaginal greyscale US was performed on admission between 34 and 36 weeks of gestation and compared to clinical grading and histopathological examination after cesarean hysterectomy. RESULTS: In total, 36 pregnant females who underwent a cesarean hysterectomy due to placenta previa complicated by PAS were included in this study. All patients had a history of previous cesarean deliveries, ranging from 1 to 5 deliveries. The US has an overall sensitivity of 33%, 55%, and 84.62%, and specificity of 100%, 75%, and 60% in detecting the 3 degrees of PAS, respectively. US cannot differentiate between the different subtypes of PAS grade 3 (a, b, and c). CONCLUSION: The overall US evaluation was highly significant in predicting the FIGO diagnosis of PAS; however, all ultrasonographic signs were equally relevant in diagnosing grade 1 and/or 2 PAS and were inaccurate in differing the subtypes of PAS grade 3.

Safety and efficacy of frameless stereotactic robot-assisted intraparenchymal brain lesion biopsies versus image-guided biopsies: a bicentric comparative study.

PURPOSE: User-friendly robotic assistance and image-guided tools have been developed in the past decades for intraparenchymal brain lesion biopsy. These two methods are gradually becoming well accepted and are performed at the discretion of the neurosurgical teams. However, only a few data comparing their effectiveness and safety are available. METHODS: Population-based parallel cohorts were followed from two French university hospitals with different surgical methods and defined geographical catchment regions (September 2019 to September 2022). In center A, frameless robot-assisted stereotactic intraparenchymal brain lesion biopsies were performed, while image-guided intraparenchymal brain lesion biopsies were performed in center B. Pre-and postoperative clinical, radiological, and histomolecular features were retrospectively collected and compared. RESULTS: Two hundred fifty patients were included: 131 frameless robot-assisted stereotactic intraparenchymal brain lesion biopsies in center A and 119 image-guided biopsies in center B. The clinical, radiological, and histomolecular features were comparable between the two groups. The diagnostic yield (96.2% and 95.8% respectively; p = 1.000) and the overall postoperative complications rates (13% and 14%, respectively; p = 0.880) did not differ between the two groups. The mean duration of the surgical procedure was longer in the robot-assisted group (61.9 ± 25.3 min, range 23-150) than in the image-guided group (47.4 ± 11.8 min, range 25-81, p < 0.001). In the subgroup of patients with anticoagulant and/or antiplatelet therapy administered preoperatively, the intracerebral hemorrhage > 10 mm on postoperative CT scan was higher in the image-guided group (36.8%) than in the robot-assisted group (5%, p < 0.001). CONCLUSION: In our bicentric comparative study, robot-assisted stereotactic and image-guided biopsies have two main differences (shorter time but more frequent postoperative hematoma for image-guided biopsies); however, both techniques are demonstrated to be safe and efficient.

Diagnostic accuracy of intrathecal fluorescein versus other radiological modalities in evaluating non-congenital skull base defects: a systematic review and meta-analysis.

PURPOSE: The intraoperative detection of cerebrospinal fluid (CSF) leaks during endoscopic skull base surgery is critical to ensure watertight sealed defects. Intrathecal fluorescein (ITF) is a valuable adjunct to intraoperative investigation. Hence, our aim is to summarize the evidence of the efficacy of ITF as an accurate diagnostic modality and reconstruction guide for non-congenital skull base defects. METHODS: Using the Cochrane Central, MEDLINE, and Embase databases, we identified studies involving the use of ITF in non-congenital CSF leaks which were published until November 2023. The STATA 18 software was used for meta-analysis. RESULTS: Fourteen studies met the inclusion criteria, in which seven studies were included in the meta-analysis. ITF was used in 1898 (90.3%) of patients, with a detection rate of 88.1%. The overall detection rate of non-congenital CSF leaks among ITF concentrations of 5% and 10% had a statistically significant pooled effect size of 2.6 (95% CI = 2.25, 2.95), while when comparing the ITF to other alternative radiological tests, it was not statistically significant with a mean difference of 0.88 (95% CI = - 0.4, 2.16). Moreover, the pooled prevalence was statistically significant in regards of the complications associated with ITF with an effect size of 0.6 (95% CI = 0.39, 0.82), indicating that 60% of patients who underwent ITF would experience at least one of the measured complications. CONCLUSION: ITF is considered as an efficient tool in localizing skull base defects. However, there was no significant results when comparing the ITF to other alternative radiological tests. Accordingly, if the ITF intervention is indicated, patients should be carefully selected based on their clinical need.

Intraoperative surgical complications of open surgery for congenital diaphragmatic hernia: a multicenter, observational study in Japan.

PURPOSE: This study aimed to clarify surgical complications associated with open surgery for congenital diaphragmatic hernia (CDH). METHODS: We performed an exploratory data analysis of the clinical characteristics of surgical complications of neonates with CDH who underwent laparotomy or thoracotomy between 2006 and 2021. Data of these patients were obtained from the database of the Japanese CDH Study Group. RESULTS: Among 1,111 neonates with left or right CDH, 852 underwent open surgery (laparotomy or thoracotomy). Of these 852 neonates, 51 had the following surgical complications: organ injury (n = 48; 6% of open surgeries); circulatory failure caused by changes in the organ location (n = 2); and skin burns (n = 1). Injured organs included the spleen (n = 30; 62% of organ injuries), liver (n = 7), lungs (n = 4), intestine (n = 4), adrenal gland (n = 2), and thoracic wall (n = 2). Fourteen of the patients who experienced organ injury required a blood transfusion (2% of open surgeries). The adjusted odds ratio of splenic injury for patients with non-direct closure of the diaphragm was 2.2 (95% confidence interval, 1.1-4.9). CONCLUSION: Of the patients who underwent open surgery for CDH, 2% experienced organ injury that required a blood transfusion. Non-direct closure of the diaphragmatic defect was a risk factor for splenic injury.

Effects of Indocyanine Green (ICG) Imaging-Assisted Cholecystectomy on Intraoperative and Postoperative Complications: A meta-Analysis.

BACKGROUND: Accurate recognition of Calot's triangle during cholecystectomy is important in preventing intraoperative and postoperative complications. The use of indocyanine green (ICG) fluorescence imaging has become increasingly prevalent in cholecystectomy procedures. Our study aimed to evaluate the specific effects of ICG-assisted imaging in reducing complications. MATERIALS AND METHODS: A comprehensive search of databases including PubMed, Web of Science, Europe PMC, and WANFANGH DATA was conducted to identify relevant articles up to July 5, 2023. Review Manager 5.3 software was applied to statistical analysis. RESULTS: Our meta-analysis of 14 studies involving 3576 patients compared the ICG group (1351 patients) to the control group (2225 patients). The ICG group had a lower incidence of postoperative complications (4.78% vs 7.25%; RR .71; 95%CI: .54-.95; P = .02). Bile leakage was significantly reduced in the ICG group (.43% vs 2.02%; RR = .27; 95%CI: .12-.62; I2 = 0; P = .002), and they also had a lower bile duct drainage rate (24.8% vs 31.8% RR = .64, 95% CI: .44-.91, P = .01). Intraoperative complexes showed no statistically significant difference between the 2 groups (1.16% vs 9.24%; RR .17; 95%CI .03-1.02), but the incidence of intraoperative bleeding is lower in the ICG group. CONCLUSION: ICG fluorescence imaging-assisted cholecystectomy was associated with a range of benefits, including a lower incidence of postoperative complications, decreased rates of bile leakage, reduced bile duct drainage, fewer intraoperative complications, and reduced intraoperative bleeding.

Importance of local and systemic factors in preventing implant displacement in the mandibular body: a scoping review of existing literature.

BACKGROUND: The aim of this research was to analyse the current literature on displaced dental implants in the mandibular body, including local and systemic variables related to their cause, and to identify the most frequent location. METHODS: The study conducted a search of three databases (Pubmed, Scopus, and Web of Science) using specific index terms such as 'dental implant', 'displacement', 'dislocation', 'displaced', and 'mandible'. The analysis focused on the direction of displacement and the characteristics of the bone tissue (bone quality, density, and quantity) in cases where dental implants were displaced. RESULTS: A total of 371 articles were obtained. Thirteen of these articles were selected and read in full. To define bone quality, the Lekholm and Zarb classification, modified by Rosas et al., was used. The type II-B bone, which is characterized by thick cortical bone surrounding cancellous bone with extremely wide medullary spaces, presented the largest number of complications. Twenty-two cases were found in which the displacement direction was horizontal. Of these, four were displaced vestibularly, fourteen lingually, and four remained in the center. Additionally, 24 cases presented vertical displacement, with 12 displaced towards the inferior border of the mandible, 9 towards the middle or adjacent to the inferior dental nerve canal, and 3 above the inferior dental nerve canal. CONCLUSION: The accidental displacement of implants within the mandibular body is associated with various risk factors, including the characteristics of the bony trabeculum and the size of the medullary spaces. It is reasonable to suggest that only an adequate pre-surgical diagnostic evaluation, with the help of high-resolution tomographic images that allow a previous evaluation of these structures, will help to have better control over the other factors, thus minimizing the risk of displacement.

A meta-analysis examining the impact of open surgical therapy versus minimally invasive surgery on wound infection in females with cervical cancer.

A meta-analysis study was executed to measure the effect of minimally invasive surgery (MIS) and open surgical management (OSM) on wound infection (WI) in female's cervical cancer (CC). A comprehensive literature study till February 2023 was applied and 1675 interrelated investigations were reviewed. The 41 chosen investigations enclosed 10 204 females with CC and were in the chosen investigations' starting point, 4294 of them were utilizing MIS, and 5910 were utilizing OSM. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were utilized to compute the value of the effect of MIS and OSM on WI in female's CC and by the dichotomous approaches and a fixed or random model. The MIS had significantly lower WI (OR, 0.23; 95% CI, 0.15-0.35, p < 0.001) with no heterogeneity (I2 = 0%) and postoperative aggregate complications (PACs) (OR, 0.49; 95% CI, 0.37-0.64, p < 0.001) in females with CC and compared OSM. However, MIS compared with OSM in females with CC and had no significant difference in pelvic infection and abscess (PIA) (OR, 0.59; 95% CI, 0.31-1.16, p = 0.13). The MIS had significantly lower WI, and PACs, though, had no significant difference in PIA in females with CC and compared with OSM. However, care must be exercised when dealing with its values because of the low sample size of some of the nominated investigations for the meta-analysis.

Differences in intraoperative and surgical outcomes between normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs) and hypertensive PPGLs: results from the PHEO-RISK STUDY.

PURPOSE: To compare the intraoperative and surgical outcomes of normotensive pheochromocytomas and sympathetic paragangliomas (PPGLs), hypertensive PPGLs and non-PPGL adrenal lesions. METHODS: This a retrospective multicenter cohort study of patients with PPGLs from 18 tertiary hospitals. A control group of histologically confirmed adrenocortical adenomas (non-PPGL group) was selected to compare intraoperative and surgical outcomes with of the normotensive PPGLs. RESULTS: Two hundred and ninety-six surgeries performed in 289 patients with PPGLs were included. Before surgery, 209 patients were classified as hypertensive PPGLs (70.6%) and 87 as normotensive PPGLs. A higher proportion of normotensive PPGLs than hypertensive PPGLs did not receive alpha presurgical blockade (P = 0.009). When we only considered those patients who received presurgical alpha blockers (200 hypertensive PPGLs and 76 normotensive PPGLs), hypertensive PPGLs had a threefold higher risk of intraoperative hypertensive crisis (OR 3.0 [95% 1.3-7.0]) and of hypotensive episodes (OR 2.9 [95% CI 1.2-6.7]) than normotensive PPGLs. When we compared normotensive PPGLs (n = 76) and non-PPGLs (n = 58), normotensive PPGLs had a fivefold higher risk of intraoperative complications (OR 5.3 [95% CI 1.9-14.9]) and a six times higher risk of postoperative complications (OR 6.1 [95% CI 1.7-21.6]) than non-PPGLs. CONCLUSION: Although the risk of intraoperative hypertensive and hypotensive episodes in normotensive PPGLs is significantly lower than in hypertensive PPGLs, normotensive PPGLs have a greater risk of intraoperative and postoperative complications than non-PPGL adrenal lesions. Therefore, it is recommended to follow the standard of care for presurgical and anesthetic management of PPGLs also in normotensive PPGLs.

The impact of case complexity in resident-performed cataract surgery.

PURPOSE: To evaluate the association of capsular dye and/or a pupil expansion device (PED) usage on the rate of major complication in resident-performed cataract extraction. METHODS: Resident cataract surgeries between 2016 and 2019 were included. The primary outcomes were anterior or posterior vitrectomy (AVx and PPVx). Cases were grouped by the use of a PED and/or capsular staining along with additional preoperative risk factors. RESULTS: Of the 1,348 cases, 371 (27.5%) documented capsular staining ("Dye-only"), 91 (6.8%) required pupil expansion ("PED-only"), and 100 (7.4%) used both capsular stain and a PED ("Both"). The remainder of cases (n=786, 58.3%) were classified as "Routine." Compared to the "Routine" group, "PED-only" and "Both" had significantly higher odds of an AVx (OR=2.90, 95% CI 1.27-6.19, P=0.01) and/or a PPVx (OR=2.33, 95% CI 1.07-5.12, P=0.04). Among the PPVx cases, the "PED-only" group has significantly higher odds than "Routine" and "Dye-only" (OR=4.64, 95% CI 1.68-12.79, P=0.01; and OR=6.48, 95% CI 1.7-25.0, P=0.005, respectively). In case-control analysis, vision, intraocular pressure, anterior chamber depth, axial length, cataract type, or severity had no significant overall association with complication. When compared to nuclear sclerotic cataract, posterior subcapsular (OR=7.86, 95% CI 1.46-42.47, P=0.017) and white/mature cataracts (OR=3.05, 95% CI 1.1-8.43, P=0.032) had increased odds of complication. CONCLUSION: Resident-performed cataract surgery frequently required capsular staining and/or a PED, and intuitively, these cases had a higher overall complication rate compared to routine cases. However, the use of a PED independently was associated with significantly higher odds of a major complication requiring an unplanned vitrectomy independent of predisposing factors.

A systematic review of the scientific evidence of venous supercharging in autologous breast reconstruction with abdominally based flaps.

BACKGROUND: Abdominally based free flaps are commonly used in breast reconstruction. A frequent complication is venous congestion, which might contribute to around 40% of flap failures. One way to deal with it is venous supercharging. The primary aim of this study was to investigate the scientific evidence for the effects of venous supercharging. METHODS: A systematic literature search was conducted in PubMed, CINAHL, Embase, and Cochrane library. The included articles were critically appraised, and certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. RESULTS: Thirty-six studies were included. Most studies had serious study limitations and problems with directness. Three studies report 'routine' use of venous supercharging and performed it prophylactically in patients who did not have clinical signs of venous congestion. Seventeen studies report on flap complications, of which one is a randomised controlled trial demonstrating statistically significant lower complication rates in the intervention group. The overall certainty of evidence for the effect of a venous supercharging on flap complications, length of hospital stay and operative time, in patients without clinical signs of venous congestion, is very low (GRADE ⊕ ⊕ ⊝ ⊝), and low on and surgical takebacks (GRADE ⊕ ⊕ ⊝ ⊝). Twenty-one studies presented data on strategies and overall certainty of evidence for using radiological findings, preoperative measurements, and clinical risk factors to make decisions on venous supercharging is very low (GRADE ⊕ ⊝ ⊝ ⊝). CONCLUSION: There is little scientific evidence for how to predict in which cases, without clinical signs of venous congestion, venous supercharging should be performed. The complication rate might be lower in patients in which a prophylactic venous anastomosis has been performed. TRIAL REGISTRATION: PROSPERO (CRD42022353591).

Bilateral medial sacrospinous ligament suture for apical suspension through natural spaces: A single-center study with low perioperative complications.

Sacrospinous ligament fixation (SSLF) is one of the most used native tissue approaches for apical suspension with a high rate of perioperative complications. This study aimed to review cases undergoing a modified SSLF and assess its perioperative adverse events. It was a retrospective study of 168 consecutive patients undergoing modified transvaginal SSLF at a single tertiary center from 2017 to 2021. The sutures were placed on the sacrospinous ligament (SSL) approaching the sacrum through natural spaces under direct vision. Moreover, it was performed bilaterally. Patient demographics and perioperative complications were reviewed. The median age was 65 years, and 85.7% (144/168) had stage III-IV prolapse. Among the 168 patients undergoing this modified SSLF, 161 were for uterovaginal prolapse, and seven were for posthysterectomy vaginal vault prolapse. 83.9% (135/161) patients were concomitant with hysterectomy, and 70.2% (118/168) were with anteroposterior colporrhaphy. The median operation time was 82 min (interquartile range [IQR], 61-100 min), and the median intraoperative blood loss was 50 ml (IQR, 30-50 ml). Two cases had pelvic hematoma, and both were cured after expectant treatment. No patient required a homologous blood transfusion, and none complained about buttock or lower limb pain 2 weeks postoperatively. Nor did injury of the ureters, bladder, or rectum occur intraoperatively. This modified transvaginal SSLF procedure was safe and had no severe perioperative complications.

Hypotension Prediction Index guided Goal Directed therapy and the amount of Hypotension during Major Gynaecologic Oncologic Surgery: a Randomized Controlled clinical Trial.

Intraoperative hypotension (IOH) is associated with increased morbidity and mortality. Hypotension Prediction Index (HPI) is a machine learning derived algorithm that predicts IOH shortly before it occurs. We tested the hypothesis that the application of the HPI in combination with a pre-defined Goal Directed Therapy (GDT) hemodynamic protocol reduces IOH during major gynaecologic oncologic surgery. We enrolled women scheduled for major gynaecologic oncologic surgery under general anesthesia with invasive arterial pressure monitoring. Patients were randomized to a GDT protocol aimed at optimizing stroke volume index (SVI) or hemodynamic management based on HPI guidance in addition to GDT. The primary outcome was the amount of IOH, defined as the timeweighted average (TWA) mean arterial pressure (MAP) < 65 mmHg. Secondary outcome was the TWA-MAP < 65 mmHg during the first 20 min after induction of GA. After exclusion of 10 patients the final analysis included 60 patients (30 in each group). The median (25-75th IQR) TWA-MAP < 65 mmHg was 0.14 (0.04-0.66) mmHg in HPI group versus 0.77 (0.36-1.30) mmHg in Control group, P < 0.001. During the first 20 min after induction of GA, the median TWA-MAP < 65 mmHg was 0.53 (0.06-1.8) mmHg in the HPI group and 2.15 (0.65-4.2) mmHg in the Control group, P = 0.001. Compared to a GDT protocol aimed to SVI optimization, a machine learning-derived algorithm for prediction of IOH combined with a GDT hemodynamic protocol, reduced IOH and hypotension after induction of general anesthesia in patients undergoing major gynaecologic oncologic surgery.Trial registration number: NCT04547491.

Inadvertent, intraoperative, non- to minimally displaced periprosthetic humeral shaft fractures in RTSA do not affect the clinical and radiographic short-term outcome.

INTRODUCTION: Little information is available on the clinical and radiographic outcome of intraoperative, non- to minimally displaced humeral fractures that occur during implantation of a stemmed, reverse shoulder prosthesis but are only recognized on routine postoperative radiographs. The goal of this study is to report the clinical and radiographic outcome for this rarely reported fracture type. MATERIALS AND METHODS: 39 conservatively treated non- to minimally displaced intraoperative periprosthetic humeral fractures after stemmed RTSA were detected from our radiographic database between 1.1.2006 and 31.1.2018. Exclusion criteria were lack of patient consent, preoperative humeral fracture, and revision arthroplasties. Clinical (absolute and relative Constant score, the Subjective Shoulder Value) and radiographic (conventional radiographs) assessment was performed preoperatively, at 6 weeks (only radiographically) and at latest follow-up with a minimum follow-up of 2 years. RESULTS: 35 patient's with a mean age of 72 years (range 32-88, SD ± 11 years) and a mean follow-up of 53 months (range 24-124, SD ± 31) were included in the study. At latest follow-up, all clinical outcome parameters except external rotation improved significantly. A complication rate of 17% (n:6) was recorded. At 6 weeks after the index surgery, none of the radiographs showed a fracture displacement or a sintering of the stem. At latest follow-up, all fractures were healed and no stem loosening was observed in any of the shoulders. CONCLUSIONS: Non- to minimally displaced intraoperative periprosthetic humeral fractures in RTSA have an incidence of about 5% in this series of mainly uncemented press-fit stems. They generally heal without any further treatment and are not associated with stem loosening or compromise the clinical outcome after primary RTSA. Except slight restriction in the postoperative rehabilitation protocol, no further attention or action is needed.

Iatrogenic nerve injury in primary and revision reverse total shoulder arthroplasty.

INTRODUCTION: Iatrogenic nerve injury in orthopedic surgery can impair functional outcomes. During the last years, a steady increase in the number of performed reverse total shoulder arthroplasties has been reported and complications associated with this procedure are continuously described. Neurological complications, however, remain underreported. The aims of this study were to calculate the incidence of iatrogenic nerve injury after primary and revision reverse total shoulder arthroplasty in a large patient cohort, as well as identify associated patient-and surgery-related risk factors. MATERIALS AND METHODS: A retrospective review of our institution's internal Reverse Total Shoulder Arthroplasty (RTSA) database from September 2005 to December 2019 was undertaken and 34 patients with iatrogenic nerve injuries were identified, resulting in a neurological complication rate of 2.6%. Group comparisons between patients with nerve injuries (n = 34) and the remaining cohort without nerve injuries (n = 1275) were performed to identify patient- and surgery-related risk factors. RESULTS: Of the 34 cases with iatrogenic nerve injury, damage to terminal nerve branches occurred in 21 patients, whereas a brachial plexus lesion was diagnosed in the other 13. Nerve revision surgery was necessary in four patients. At final follow-up 13 patients (45%) had residual motor deficits and 17 (59%) had residual sensory deficits. Higher numbers of previous surgeries of the affected shoulder correlated with subsequent nerve injury (p = 0.035). Operative time was significantly longer in patients, who developed a neurologic deficit, showing a correlation between duration of surgery and occurrence of nerve injury (p = 0.013). Patients with neurologic complications were significantly younger than patients without nerve damage (median 68 vs. 72 years, p = 0.017). CONCLUSIONS: In specialists' hands reverse total shoulder arthroplasty is a rather safe procedure regarding the risk of neurologic injury. However, multiple previous surgeries of the affected shoulder increase the risk of neurological complications. Cases with post-operative neurologic compromise are rare and usually recover well, with few patients suffering long-term functional deficits from iatrogenic nerve injury. LEVEL OF EVIDENCE: Level III, retrospective cohort study.
