Living-Donor Uterus Transplantation: A Clinical Review

Uterus transplantation (UTx) is currently the only available treatment for absolute uterine factor infertility. More than 90 uterus transplantations have been performed worldwide, mostly from living donors. Living-donor (LD) UTx is a challenging surgical procedure since it poses ethical issues, and it is a high-risk and invasive surgery with higher hysterectomy-related risks compared to conventional hysterectomy. A total of 59 living-donor hysterectomies have been reported in the literature, including 35 performed with a laparotomic approach, 20 with a robotic approach and 4 with a laparoscopic approach. The mean donor age was 45.6 ± 9.1 years, and 22 were unrelated with the recipients, 34 were emotionally related (27 mothers, 5 sisters, 2 mother’s sisters). The mean recipient age was 28.8 ± 4.5 years. Mayer–Rokitansky–Küster–Hauser syndrome was the most common indication for uterus transplant. Robotic living-donor hysterectomy had the longest operative time but resulted in a lower blood loss and postoperative stay compared to laparotomic and laparoscopic approaches. Twenty-nine births from LD-UTx have been reported, four after robotic living-donor hysterectomy and twenty-five after a laparotomic procedure. UTx is now an effective treatment for women with UFI. While living-donor UTx in some cases may be considered an experimental procedure, it offers the extraordinary possibility to give women the opportunity to have a pregnancy. Many efforts should be made to reduce the potential risks for donors, including the use of mini-invasive techniques, and the efficacy of UTx in the recipients, giving the potential harm of immunosuppression in a recipient of a non-life-saving organ.

Impact of Metabolic Syndrome on Post-Operative Infection in Patients Undergoing Flexible Ureteroscopy Lithotripsy.

Background: To investigate retrospectively whether metabolic syndrome (MetS) of flexible ureteroscopy (fURS) lithotripsy can be used to predict post-operative infection. Patients and Methods: After screening, 1,110 patients who received fURS lithotripsy for upper urinary tract stones in our center between January 2015 and December 2022 were analyzed retrospectively. Patients were divided into MetS-positive group and MetS-negative group. Post-operative infection was divided into fever, urosepsis, and septic shock. Relevant data during the peri-operative period were collected. Univariable and multivariable logistic regression analyses were adopted to estimate the impact of metabolic syndrome on post-operative infection in patients undergoing fURS lithotripsy. Results: Among the 1,110 patients, 427 tested positive for MetS, whereas 683 tested negative. Eighty-eight patients suffered from fever (67 patients in the MetS-positive group and 21 in the MetS-negative group). Forty-nine patients had urosepsis (29 patients in the MetS-positive group and 20 in the MetS-negative group), of whom seven patients developed septic shock. No patient developed multiple organ failure or died because of infection. The prevalence of post-operative infections in the MetS-positive group was higher than that in the MetS-negative group (p < 0.001). Multivariable logistic regression analyses showed that diabetes mellitus, MetS-positive, positive urine culture, and longer operation time were positively correlated with post-operative fever. Positive MetS, positive urine culture, and longer operation time were strongly correlated with post-operative urosepsis. Conclusions: Metabolic syndrome was found to be associated with post-operative infection in patients undergoing fURS lithotripsy, suggesting it can serve as a predictive factor.

Combined Anterior–Posterior vs. Posterior-Only Approach in Adult Spinal Deformity Surgery: Which Strategy Is Superior?

Introduction: Whether a combined anterior–posterior (AP) approach offers additional benefits over the posterior-only (P) approach in adult spinal deformity (ASD) surgery remains unknown. In a cohort of patients undergoing ASD surgery, we compared the combined AP vs. the P-only approach in: (1) preoperative/perioperative variables, (2) radiographic measurements, and (3) postoperative outcomes. Methods: A single-institution, retrospective cohort study was performed for patients undergoing ASD surgery from 2009 to 2021. Inclusion criteria were ≥5-level fusion, sagittal/coronal deformity, and 2-year follow-up. The primary exposure was the operative approach: a combined AP approach or P alone. Postoperative outcomes included mechanical complications, reoperation, and minimal clinically important difference (MCID), defined as 30% of patient-reported outcome measures (PROMs). Multivariable linear regression was controlled for age, BMI, and previous fusion. Results: Among 238 patients undergoing ASD surgery, 34 (14.3%) patients underwent the AP approach and 204 (85.7%) underwent the P-only approach. The AP group consisted mostly of anterior lumbar interbody fusion (ALIF) at L5/S1 (73.5%) and/or L4/L5 (38.0%). Preoperatively, the AP group had more previous fusions (64.7% vs. 28.9%, p &lt; 0.001), higher pelvic tilt (PT) (29.6 ± 11.6° vs. 24.6 ± 11.4°, p = 0.037), higher T1 pelvic angle (T1PA) (31.8 ± 12.7° vs. 24.0 ± 13.9°, p = 0.003), less L1-S1 lordosis (−14.7 ± 28.4° vs. −24.3 ± 33.4°, p &lt; 0.039), less L4-S1 lordosis (−25.4 ± 14.7° vs. 31.6 ± 15.5°, p = 0.042), and higher sagittal vertical axis (SVA) (102.6 ± 51.9 vs. 66.4 ± 71.2 mm, p = 0.005). Perioperatively, the AP approach had longer operative time (553.9 ± 177.4 vs. 397.4 ± 129.0 min, p &lt; 0.001), more interbodies placed (100% vs. 17.6%, p &lt; 0.001), and longer length of stay (8.4 ± 10.7 vs. 7.0 ± 9.6 days, p = 0.026). Radiographically, the AP group had more improvement in T1PA (13.4 ± 8.7° vs. 9.5 ± 8.6°, p = 0.005), L1-S1 lordosis (−14.3 ± 25.6° vs. −3.2 ± 20.2°, p &lt; 0.001), L4-S1 lordosis (−4.7 ± 16.4° vs. 3.2 ± 13.7°, p = 0.008), and SVA (65.3 ± 44.8 vs. 44.8 ± 47.7 mm, p = 0.007). These outcomes remained statistically significant in the multivariable analysis controlling for age, BMI, and previous fusion. Postoperatively, no significant differences were found in mechanical complications, reoperations, or MCID of PROMs. Conclusions: Preoperatively, patients undergoing the combined anterior–posterior approach had higher PT, T1PA, and SVA and lower L1-S1 and L4-S1 lordosis than the posterior-only approach. Despite increased operative time and length of stay, the anterior–posterior approach provided greater sagittal correction without any difference in mechanical complications or PROMs.

Prophylactic para-aortic lymph node dissection after neoadjuvant chemotherapy for gastric cancer with bulky lymph node metastasis.

344 Background: Neoadjuvant chemotherapy (NAC) followed by D2 gastrectomy with para-aortic lymph node dissection (PAND) is the standard treatment for gastric cancer with extensive lymph node metastasis (ELM) in Japan. ELM includes bulky lymph node metastasis along the celiac artery and its branches (Bulky N2) and metastasis of para-aortic lymph nodes (PAN). However, the benefit of PAND for gastric cancer with Bulky N2 but without PAN involvement is unclear. The aim of this study was to evaluate the efficacy of prophylactic PAND after NAC for this subgroup of patients. Methods: We retrospectively reviewed 21 patients who underwent NAC followed by curative (R0) gastrectomy for Bulky N2 (+) but PAN (-) gastric cancer from 2008 to 2019. Bulky lymph node was defined as one lymph nodes ≥ 3cm or two adjacent lymph nodes ≥ 1.5cm each. PAN metastasis included no. 16a2/16b1 lymph node metastasis. PAND was defined as systematic lymph node dissection of PAN. Patients were divided into two groups: a D2+PAND group (11 patients) and a D2 group (10 patients). We compared the clinicopathological features, recurrence patterns, and survival outcomes between the two groups. Results: The most common NAC regimen was S-1+cisplatin (12 patients: 57%), and other regimens in D2+PAND group included docetaxel+S-1+cisplatin or oxaliplatin. The D2+PAND group had longer operation time (p=0.006), and tended toward more undifferentiated histological type (p=0.063), better pathological response (p=0.086), and higher rate of adjuvant chemotherapy (p=0.090) than the D2 group. The ypStage was similar between the two groups. Pathological PAN metastasis was detected in two patients (18%) in D2+PAND group. Recurrence occurred in seven (70%) patients in D2 group and three (27%) patients in D2+PAND group, and lymph node recurrence was observed in four (40%), and one (10%) patients, respectively. The D2+PAND group had significantly better overall survival, recurrence-free survival, and disease-specific survival than the D2 group (p=0.008, 0.008, and 0.020, respectively). Conclusions: Prophylactic PAND after NAC may reduce recurrence risk for locally advanced gastric cancer with Bulky N2 but without PAN involvement.

Advantages of robotic surgery for advanced gastric cancer in short-term outcomes: A single-center retrospective study using propensity score matching.

343 Background: The advantages of robotic gastrectomy (RG) for gastric cancer are being demonstrated. However, there are few reports that have focused on advanced gastric cancer and examined the advantages of RG for laparoscopic gastrectomy (LG). We conducted the following study to clarify the advantages of RG for advanced gastric cancer. Methods: This single-center retrospective study reviewed the clinical data of 1531 patients who underwent either RG or LG from 2014 to 2023. 473 patients were with clinically diagnoses as having advanced gastric cancer. They were divided into the RG group (n = 143) and the LG group (n = 330). Propensity score matching was employed to adjust the background of the two groups, as covariates of age, gender, BMI, surgical method (distal gastrectomy/total gastrectomy), stage (early cancer/advanced cancer), and presence or absence of preoperative chemotherapy. Then, the treatment results were compared and examined. Results: 130 patients in each group were extracted by propensity score matching. There were no significant differences in age, gender, and ECOG-PS between the two groups. Compared to the LG group, the RG group had more cases with deeper invasion depth ≥T3 (93.1 vs 84.6%, P = 0.04), more D2 dissection (96.9 vs 88.5%, P = 0.01), and longer operative time (339.5 vs 294.5min, P &lt;0.01). The number of retrieved lymph nodes was larger (49.5 vs. 44, P &lt;0.01) in the RG group. Importantly, in the RG group, there were fewer complications with Clavien-Dindo (CD) classification ≥Grade II (11.5 vs 21.5%, P = 0.04) and CD classification ≥Grade III (0.8% vs 6.9%, P = 0.01). Postoperative hospital stay was shorter (8 vs 9 days, P = 0.01) in the RG group. Conclusions: RG for advanced gastric cancer has the potential to reduce complications compared to LG. Long-term survival outcomes should be investigated.

Reduction in drain-related adverse events using the barbed suture method for chest tube wound closure.

A chest tube is usually placed in patients undergoing general thoracic surgery. Although the barbed suture method has been introduced for chest tube wound closure, its superiority to the conventional suture methods for drain management remains unclear. The study aimed to determine whether the barbed suture method could reduce drain-related adverse events compared to the conventional method. We retrospectively reviewed the medical records of patients who underwent general thoracic surgery between January 2021 and December 2022, 1year before and after the introduction of the barbed suture method at our institution. Patients who underwent the barbed suture or conventional method were included. Univariate and multivariate analyses of drain-related adverse events were performed. Of the 250 participants, 110 and 140 underwent the barbed suture method and conventional suture method, respectively. The univariate analysis showed that a higher body mass index, preoperative malignant diagnosis, lobectomy, longer operative time, larger tube size, longer chest drainage duration, surgical complications, and conventional method were risk factors for drain-related adverse events. The multivariate analysis showed that the barbed suture method was a protective factor against drain-related adverse events (odds ratio 0.267; 95% confidence interval 0.103-0.691; P = 0.007). The barbed suture method could reduce drain-related adverse events compared to the conventional method. Therefore, it might be a potential standard method for chest tube wound closure in patients undergoing general thoracic surgery.

Comparison of substernal and posterior mediastinal route of reconstruction after minimally invasive esophagectomy for esophageal cancer

BackgroundSubsternal (ST) and posterior mediastinal (PM) routes are the two most common for reconstruction after esophagectomy with cervical anastomosis. Recent evidence showed similar outcomes between the routes; thus, the superior choice remained controversial. This study aimed to compare the short-term outcomes of the ST to the PM route for reconstruction after esophagectomy for esophageal cancer (EC).MethodThis retrospective cohort study included 132 patients who underwent McKeown minimally invasive esophagectomy (MIE) with gastric conduit for EC between March 2015 and December 2022. Among these, 89 and 43 patients received the ST route and PM route for reconstruction, respectively. Short-term outcomes including operative characteristics, postoperative morbidity, and mortality were evaluated.ResultThere was no conversion from ST to PM route. The ST group had longer operating time (375 min vs. 341 min). Oral feeding initiation, postoperative hospital stays, and overall complication rates were comparable in the two groups. The rate and severity of anastomotic leakage were similar between the groups. The ST group had a significantly lower incidence of postoperative ICU admission and pneumonia compared to the PM group (5.6% vs. 16.3% and 19.1% vs. 37.2%, respectively). Azygos vein bleeding, obstruction at feeding jejunostomy site, and conduit–trachea fistula were severe complications that only occurred in PM route.ConclusionST route was superior to PM route in term of postoperative ICU admission and pneumonia. This route may prevent severe complications that only occur in PM route. ST route can be favorable option for reconstruction after McKeown MIE for EC.

Surgical site infection after trochanteric and subtrochanteric fractures: a single centre retrospective analysis

Surgical site infection (SSI) following osteosynthesis of trochanteric or subtrochanteric fractures is a rare but serious complication with incidence rate ranging from 1 to 3%. SSIs are associated with higher mortality and increased length of hospital stay resulting in higher healthcare costs and loss of life quality. In this retrospective analysis all patients with SSI following osteosynthesis of trochanteric or subtrochanteric fractures at the Department of Trauma Surgery were identified. We included all surgical procedures performed from 1992 to 2018, using data from electronic health records and SSI-Trauma-Registry. The aim was to describe epidemiological data, as well as to identify parameters correlating with the occurrence of SSI and mortality. Of 2753 patients, 53 (1.9%) developed SSI. Longer operative time was demonstrated among patients with SSI (P = 0.008). Mortality during the first postoperative year was significantly higher in the SSI group (32.1% vs. 19.1%; P = 0.018), with detection of methicillin-sensitive (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA; HR 4.13, CI 95% 1.24–13.80; P = 0.021) or Enterococcus spp. (HR 5.58, CI 95% 1.67–18.65; P = 0.005) being independent risk factors. Male sex (HR 2.25, 95% CI 1.86–2.73; P < 0.001) and higher mean age (HR 1.05, 95% CI 1.04–1.06; P < 0.001) were found to be predictors for 1-year mortality in non-infected patients. SSI rate was low with 1.9% and longer duration of surgery was associated with infection. Patients with SSI had a higher 1-year mortality, with detection of MSSA, MRSA and enterococci significantly increasing the risk of dying. Male sex and higher age were risk factors for one-year mortality in patients without SSI.

Associations of parecoxib and other variables with recovery and safety outcomes in total knee arthroplasty: insights from a retrospective cohort study.

Early mobilization post-total knee arthroplasty (TKA) significantly affects patient outcomes. While parecoxib is known to reduce postoperative pain and morphine use with a favorable safety profile, its impact on mobilization timing post-TKA remains uncertain. This retrospective study aims to assess parecoxib's influence on postoperative mobilization timing in TKA patients without compromising safety. This study included unilateral TKA patients treated for primary knee osteoarthritis under general anesthesia. We divided the study period into two intervals, 2007-2012 and 2013-2018, to evaluate temporal differences. Both the control group and parecoxib group received standard postoperative oral analgesics and as-needed intramuscular morphine. The control group did not receive parecoxib, while the parecoxib group did. Primary outcomes compared postoperative complications and mobilization timing between groups, with secondary outcomes including length of hospital stay (LOS), Visual Analog Scale (VAS) scores for pain, as-needed morphine use, and postoperative nausea/vomiting. Parecoxib did not increase postoperative complications. Unmatched comparison with patients in controlled group found that patients in parecoxib group had significantly shortened mobilization time (2.2 ± 1.1 vs. 2.7 ± 1.6 days, P < 0.001) and LOS (6.7 ± 2.5 vs. 7.2 ± 2.1 days, P = 0.01). Multivariate analysis linked parecoxib use with faster mobilization (β = -0.365, P < 0.001) but not LOS. Males showed increased mobilization time and LOS compared to females during the period of 2007-2018, but gender had no significant association with LOS during the period of 2013-2018. The 2013-2018 period saw significant reductions in both mobilization time and LOS. Use of a tourniquet and local infiltration analgesia showed no significant impact. ASA classification 1-2 was positively associated with faster mobilization but not LOS. Longer operation times were linked to delayed mobilization and increased LOS. In this study, intravenous parecoxib injection, female gender, and shorter OP time had consistent positive association with shorter time to mobilization after individual multivariate analysis in 2 different period. The use of parecoxib had consistent no significant association with LOS. Only shorter OP time was consistent positive associated with shorter LOS.

Comparison of the surgical outcomes of the posterior approach, video-assisted thoracic surgery, and combined approach for thoracic dumbbell tumors based on a new classification: a retrospective study

The appropriate surgical treatment strategy was based on the regions of tumor invasion. There is no classification to aid the surgeon in selection. A retrospective study of the clinical data of patients who underwent resection of thoracic dumbbell tumors at the Neurosurgery and Thoracic Surgery Department of Hospital between January 1, 2016, and December 31, 2021 was conducted. Patient data, images, and surgical outcome data were collected. The thoracic spine was divided into areas A, B, and C with respect to the line through the middle of the intervertebral foramen and the line of the costo-transverse joint lateral margin in the horizontal plane. Type I tumors were located in areas A or A and B, type II tumors were located in areas B or B and C, and type III tumors were located in areas A, B, and C. Fifty-five patients with thoracic dumbbell tumors were surgically treated (mean age, 43.1 years; 22 (40%) female). The patients with type I and III tumors underwent the posterior approach, type III tumors had more bleeding during the operation and longer operation times than type I. Among the patients with type II tumors who underwent video-assisted thoracic surgery and the posterior approach, the posterior group had more bleeding and a longer operation time than the others. The patients with type III tumors underwent the combined approach and the posterior approach; although there was no clear difference in the bleeding volume or operation time, the combined approach group had a lower incidence of complications. The new classification of different types of thoracic dumbbell tumors can simply and effectively guide the selection of surgery.

Comparison of clinical outcomes between unilateral biportal endoscopic discectomy and percutaneous endoscopic interlaminar discectomy for migrated lumbar disc herniation at lower lumbar spine: a retrospective controlled study

BackgroundBoth Unilateral Biportal Endoscopic Discectomy (UBED) and Percutaneous Endoscopic Interlaminar Discectomy (PEID) have resulted in favorable clinical outcomes in the management of LDH. The aim of this study is to comprehensively compare the efficacy of UBED and PEID in treating migrated LDH in the lower lumbar spine, with a specific focus on high-grade migrated LDH.Methods96 patients who underwent UBED (31 cases) and PEID (65 cases) procedures were enrolled in the study. All patients received a minimum follow-up period of 6 months. Clinical outcomes of the patients were assessed with incision length, operation time, total hemoglobin loss, hospital stay, intraoperative fluoroscopy times, visual analogue scale (VAS) for lower back and leg pain, Oswestry disability index (ODI), modified MacNab criteria, complications, area of lamina loss and increased intervertebral height.ResultsThe VAS scores for lower back and leg pain and ODI significantly decreased in both groups after the operation. Preoperatively, at 1 day, 1 month, and 6 months after the procedure, the VAS and ODI scores exhibited no significant differences between the two groups. There was no significant difference in terms of modified MacNab criteria, area of lamina loss, and increased intervertebral height. The UBED group had a longer incision length, operation time and postoperative hospital stay, and fewer intraoperative fluoroscopy times than to the PEID group. Complications were noted in both groups throughout the follow-up period, but there was no significant difference in the rate of complications. Moreover, there were no notable differences in clinical outcomes between the two groups in the high-grade migrated LDH.ConclusionsBoth UBED and PEID could achieve favorable clinical outcomes for treating migrated LDH at the lower lumbar spine. Despite the longer operative time and postoperative hospital stay associated with the UBED group, UBED remains safe and innovative for treating migrated LDH at the lower lumbar spine.

Impact of tumor size on the outcomes of hepatic resection for hepatocellular carcinoma: a retrospective study

BackgroundTo evaluate the impact of tumor size on the perioperative and long-term outcomes of liver resection for hepatocellular carcinoma (HCC).MethodsWe reviewed the patients’ data who underwent liver resection for HCC between November 2009 and 2019. Patients were divided into 3 groups according to the tumor size. Group I: HCC < 5 cm, Group II: HCC between 5 to 10 cm, and Group III: HCC ≥ 10 cm in size.ResultsThree hundred fifteen patients were included in the current study. Lower platelets count was noted Groups I and II. Higher serum alpha-feto protein was noted in Group III. Higher incidence of multiple tumors, macroscopic portal vein invasion, nearby organ invasion and presence of porta-hepatis lymph nodes were found in Group III. More major liver resections were performed in Group III. Longer operation time, more blood loss and more transfusion requirements were found in Group III. Longer hospital stay and more postoperative morbidities were noted in Group III, especially posthepatectomy liver failure, and respiratory complications.The median follow-up duration was 17 months (7–110 months). Mortality occurred in 100 patients (31.7%) and recurrence occurred in 147 patients (46.7%). There were no significant differences between the groups regarding recurrence free survival (Log Rank, p = 0.089) but not for overall survival (Log Rank, p = 0.001).ConclusionHCC size is not a contraindication for liver resection. With proper selection, safe techniques and standardized care, adequate outcomes could be achieved.

Neurological prognosis in surgically treated acute aortic dissection with brain computed tomography perfusion.

The aim of this study was to explore the prognostic value of brain computed tomography perfusion (CTP) for postoperative new stroke in acute type A aortic dissection (ATAAD) patients. Patients with ATAAD and suspected cerebral malperfusion who underwent brain CTP and surgical repair were retrospectively analysed. Brain perfusion was quantified mainly with the averaged cerebral blood flow. Significant clinical and imaging findings were identified through univariable and multivariable regression analysis. Furthermore, the added prognostic benefit of perfusion parameters was confirmed with the receiver operating characteristic curves in the entire cohort and subgroup analysis. The incidence of postoperative new stroke was 30.8% (44/143). The independent adjusted predictors of postoperative new stroke included an impaired averaged cerebral blood flow (ml/100 ml/min) (odds ratio: 0.889; P < 0.001), severe stenosis (odds ratio: 5.218; P = 0.011) or occlusion (odds ratio: 14.697; P = 0.048) of the true lumen in common carotid artery (CCA), hypotension on admission (odds ratio: 9.644; P = 0.016) and a longer surgery time (odds ratio: 1.593; P = 0.021). The area under the receiver operating characteristic curves significantly improved after adding perfusion parameters to clinical and computed tomography angiography characteristics (P = 0.048). This benefit was more pronounced in patients with severe stenosis or occlusion in CCA true lumen (P = 0.004). Brain CTP could be a useful prognostic tool for surgically treated ATAAD patients and especially beneficial in patients with severe stenosis or occlusion of the CCA true lumen.

Risk Factors Analysis and Nomogram Model Establishment of Hidden Blood Loss in Overweight and Obese Elderly Patients After Total Hip Arthroplasty.

Total hip arthroplasty (THA) has become the first-choice treatment for elderly patients with end-stage hip disease. The high amount of hidden blood loss (HBL) in overweight and obese patients after THA not only affects rapid recovery, but also results in a greater economic burden. We aimed to identify risk factors that contribute to elevated HBL in overweight and obese patients after THA by retrospective analysis, and establish a nomogram prediction model for massive HBL in overweight and obese patients after THA. A total of 505 overweight and obese patients treated with THA were included and randomly divided into modeling and validation sets according to a 7:3 ratio. The demographic and relevant clinical data of the patients were collected. The independent risk factors affecting HBL after THA in overweight and obese patients were obtained by Pearson, independent sample T-test, and multiple linear regression analyses. R software was used to establish a nomogram prediction model for postoperative HBL, as well as a receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA). HBL was 911±438 mL, accounting for 79.5±13.1% of the total perioperative blood loss (1104±468 mL). A multiple linear regression analysis showed that HBL was associated with necrosis of the femoral head, absence of hypertension, longer operative time, higher preoperative erythrocytes, and higher preoperative D-dimer levels. The areas under the ROC curve (AUC) for the modeling and validation sets were 0.751 and 0.736, respectively, while the slope of the calibration curve was close to 1. The DCA curve demonstrated a better net benefit at a risk of HBL ≥1000 ml in both the training and validation groups. HBL was an important component of total blood loss (TBL) after THA in overweight and obese patients. Necrosis of the femoral head, absence of hypertension, longer operative time, higher preoperative erythrocytes, and higher preoperative D-dimer levels were independent risk factors for postoperative HBL in these patients. The predictive model constructed based these data had better discriminatory power and accuracy, and could result in better net benefit for patients.

Laparoscopy and Laparotomy for Endometrioid Adenocarcinoma: Short‐ and Long‐Term Outcomes’ Comparison

Aims. To analyze the short‐term and long‐term outcomes of laparoscopy versus laparotomy in treatment of endometrioid adenocarcinoma and examine the benefits of laparoscopy. Methods. From January 2012 to July 2020, 693 endometrioid adenocarcinoma patients undergoing laparoscopy versus laparotomy were retrospectively identified and enrolled in this study. Basic information for the patients, their perioperative indexes, and recurrence rates were reviewed to assess the therapeutic effect of these two approaches for endometrioid adenocarcinoma. Results. A total of 365 endometrioid adenocarcinoma patients underwent laparoscopy, and 328 patients underwent laparotomy. When compared with the laparotomic group, the laparoscopic group had longer operative times, lower intraoperative bleeding volumes, and shorter postoperative hospital stays. The rate of less‐radical hysterectomy and radical hysterectomy performed in the laparoscopic group (59/365, 16.16%) was significantly lower than that in the laparotomic group (162/328, 49.39%). There was no statistically significant difference in the local recurrence rate between the two groups; however, the remote recurrence rate in the laparotomic group (15/308, 4.87%) was significantly higher than that in the laparoscopic group (3/351, 0.85%). A further subgroup analysis revealed a higher survival benefit both in I/II patients (314/314, 100%, vs. 7/242, 28.93%) and III/IV patients (35/37, 94.59%, vs. 51/66, 77.27%) in the laparoscopic group, when compared with the laparotomic group. Conclusion. Patients who received laparoscopic surgery had a faster surgical recovery and a lower postoperative recurrence rate in the short term than patients who received laparotomic surgery. Laparoscopic surgery is a safe and effective treatment for endometrioid adenocarcinoma.

Complications Following Gender-Affirming Phalloplasty: A NSQIP Review

Abstract Background Gender-affirming phalloplasty has a complication rate as high as 76.5%. This is the first study to determine the predictors of 30-day complications following phalloplasty using a national registry. Methods The National Surgical Quality Improvement Program database (2012–2021) was queried for transgender men and Current Procedural Terminology codes pertaining to flap or microsurgery procedures to select for single- and first-stage phalloplasty cases. Included were patients with a length of total hospital stay ≥ 5 days and operating time &gt; 4 hours to select for primary phalloplasty cases. The primary outcome was incidence of major and minor complications, and the secondary outcome was indication for unplanned reoperation. Bivariate analysis and multivariate logistic regression were performed to determine significant predictors of complications. Results Of 90 patients, 18 (20.0%) patients developed at least one complication. The most common complication was unplanned reoperation (n = 10, 11.1%) due to hematoma evacuation (n = 3, 30.0% of reoperations, 3.3% of all patients). A total of 43 (47.8%) underwent single-stage phalloplasty, and 47 (52.2%) underwent first-stage phalloplasty. Compared with patients without complications, those with minor complications are more likely to have had single-stage phalloplasty (n = 37 [45.1%], n = 6 [75.0%]; p = 0.145), but the association was not statistically significant. Longer operating time was associated with greater odds of major complications (adjusted odds ratio [aOR] 95% confidence interval [CI] 1.01 [1.002–1.018]). Patients who smoked within 1 year of surgery had 123 times the odds of 30-day minor complications (surgical site infection, urinary tract infection, wound dehiscence, pneumonia) compared with nonsmokers (aOR [CI] 123.3 [1.4– &gt; 100.0]). Conclusion There were no significant differences in complication rates between single- and first-stage phalloplasties. Patients should be counseled about the overall risk of 30-day complications following phalloplasty. Reducing operating time, smoking cessation, and strict preoperative nicotine testing may assist in mitigating odds of 30-day complications following phalloplasty.

Exploring the Impact of Gender-Specific Approaches inRetrograde Intrarenal Surgery: Effects on Operative Efficiency and Patient Recovery.

Very limited data are available exploring the potential influence of gender on Retrograde Intrarenal Surgery outcomes. This study investigates the gender-specific influence of ShuoTongureteroscopy (ST-urs) and Flexible Ureteroscopy (F-urs) surgeries on operation efficacy and patient recovery in a sample of the Somali population. We enrolled 390 participants. Participants were stratified into four gender-specific subgroups based on ureteroscopy operation type: 27.7% males in S-urs (group1), 44.4% females in S-urs (group2), 18.7% males in F-urs (group3), and 9.2% females in F-urs (group4). Primary outcomes included operation time, postoperative hospital stay duration, and VAS Pain Score. Multivariate logistic regression was used to assess associations. The mean age was 29.53 ± 7.61 years, 72.1% male and 27.9% female, with 46.4% of the patients undergoing ST-urs and 53.6% undergoing F-urs. Women had higher odds of prolonged hospital stays (OR = 2.62, 95% CI: 1.43-4.82, p < 0.001) and post-operation pain (OR = 5.06, 95% CI: 2.95-8.68, p = 0.002). Among men who underwent F-urs procedure, there was a significantly higher odds ratio (OR) of 6.14 (95% CI: 2.86-13.19, p < 0.001) for experiencing a long operation time. Conversely, for females, those who underwent S-urs surgery had a notably lower OR of 0.32 (95% CI: 0.13-0.79, p = 0.013) for long operation time, whereas those who underwent F-urs surgery exhibited a substantially elevated OR of 5.36 (95% CI: 1.85-15.53, p < 0.001). Both females undergoing F-urs surgery (OR: 5.16, 95% CI: 2.61-10.21, p < 0.001) and those undergoing F-urs surgery (OR: 5.25, 95% CI: 2.17-12.73, p < 0.001) experienced significantly higher post-operative pain. Our research reveals gender disparities in retrograde intrarenal surgery outcomes. Women experience longer hospital stays and higher postoperative pain levels compared to men. F-urs procedures are associated with longer operation times and hospital stays, particularly affecting women. Contrarily, ST-urs offers shorter operation times for women but leads to prolonged hospital stays and heightened postoperative pain.

Lymphadenectomy in clinically early epithelial ovarian cancer and survival analysis (LILAC): a Gynecologic Oncology Research Investigators Collaboration (GORILLA-3002) retrospective study.

This study aimed to evaluate the therapeutic role of lymphadenectomy in patients surgically treated for clinically early-stage epithelial ovarian cancer (EOC). This retrospective, multicenter study included patients with clinically early-stage EOC based on preoperative abdominal-pelvic computed tomography or magnetic resonance imaging findings between 2007 and 2021. Oncologic outcomes and perioperative complications were compared between the lymphadenectomy and non-lymphadenectomy groups. Independent prognostic factors were determined using Cox regression analysis. Disease-free survival (DFS) was the primary outcome. Overall survival (OS) and perioperative outcomes were the secondary outcomes. In total, 586 patients (lymphadenectomy group, n=453 [77.3%]; non-lymphadenectomy groups, n=133 [22.7%]) were eligible. After surgical staging, upstaging was identified based on the presence of lymph node metastasis in 14 (3.1%) of 453 patients. No significant difference was found in the 5-year DFS (88.9% vs. 83.4%, p=0.203) and 5-year OS (97.2% vs. 97.7%, p=0.895) between the two groups. Using multivariable analysis, lymphadenectomy was not significantly associated with DFS or OS. However, using subgroup analysis, the lymphadenectomy group with serous histology had higher 5-year DFS rates than did the non-lymphadenectomy group (86.5% vs. 74.4%, p=0.048; adjusted hazard ratio=0.281; 95% confidence interval=0.107-0.735; p=0.010). The lymphadenectomy group had longer operating time (p<0.001), higher estimated blood loss (p<0.001), and higher perioperative complication rate (p=0.004) than did the non-lymphadenectomy group. In patients with clinically early-stage EOC with serous histology, lymphadenectomy was associated with survival benefits. Considering its potential harm, lymphadenectomy should be performed according to histologic subtype and subsequent chemotherapy in patients with clinically early-stage EOC.

Effect of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy on epithelial ovarian, fallopian tube, and peritoneal cancer: An institutional review of outcomes and its clinical implications

BACKGROUND: Ovarian, fallopian tube, and peritoneal cancer patients with advanced-stage diagnosis or recurrences spread to the peritoneal surface of the abdomen. Hyperthermic intraperitoneal chemotherapy (HIPEC) can penetrate and eradicate tumors that are microscopic up to those with a diameter of 2.5 cm from the peritoneal surface following cytoreductive surgery (CRS). OBJECTIVES: The study aimed to determine the efficacy and safety of CRS with HIPEC versus CRS alone for patients with epithelial ovarian, fallopian tube, and peritoneal cancer. MATERIALS AND METHODS: This retrospective cohort study included 50 patients (20 patients underwent CRS + HIPEC, while 30 patients underwent CRS alone). Records of these patients from January 2014 to June 2020 were reviewed, tabulated, and analyzed. RESULTS: The difference in recurrence rate between CRS with HIPEC and CRS alone was not statistically significant (50% vs. 43%, P = 0.774). The median time to recurrence was 10 and 9 months, respectively (P = 0.636). Five percent in the HIPEC group succumbed to the disease, while 13% died in the CRS alone group (P = 0.636). More post-operative complications were noted in the HIPEC group (45% vs. 10%, P = 0.007), but among these, only 2 cases had grade 3 to 4 complications (10%). The addition of HIPEC in the management of these patients resulted in a longer operative time (360 vs. 240 min, P &lt; 0.001) and postoperative hospital stay (8 vs. 6 days, P = 0.026). There were no intra- or peri-operative mortalities in both groups. CONCLUSION: CRS with HIPEC and CRS alone showed similar time to recurrence and recurrence rate. CRS with HIPEC had low risk of grade 3-4 complications and may still be considered as a treatment option for advanced, progressive, and recurrent epithelial ovarian, fallopian tube, and peritoneal cancer.

Significance of prothrombin, activated partial thromboplastin, and thrombin times in early rehabilitation after tibial fracture surgery.

To assess the role of prothrombin time (PT), activated partial thromboplastin time (APTT), and thrombin time (TT) in guiding early rehabilitation following tibial fracture surgery. A retrospective analysis was conducted on 168 patients treated for tibial fractures from May 2020 to May 2022. Patients were divided into good and poor rehabilitation groups based on treatment outcomes. Data on age, gender, BMI, Schatzker classification, operation time, blood loss, PT, APTT, and TT were collected for univariate analysis. ROC curve analysis determined optimal cut-off values, followed by multivariable logistic regression to identify independent risk factors. A nomogram prediction model was then constructed. Independent risk factors for early recovery included age ≥45 years, Schatzker type III, operation time ≥99.5 minutes, APTT≥28.5 seconds, and TT≥13.5 seconds. The nomogram model demonstrated high prediction accuracy with a C-index of 0.980. Prolonged APTT, extended TT, longer operation time, and higher Schatzker classification were identified as independent risk factors influencing early recovery post-surgery. A logistic regression-based prediction model was developed, facilitating the design of personalized rehabilitation training programs to improve patient outcomes.
