Effect of lower urinary tract conditions on surgical outcomes of different suburethral sling procedures for female stress urinary incontinence.

The suburethral sling procedure has been widely used as the first-line treatment for female stress urinary incontinence (SUI). This study retrospectively compared the long-term surgical outcomes and complications between retropubic and transobturator suburethral sling procedures. From 2010 to 2022, a total of 533 women with SUI underwent retropubic pubovaginal sling (PVS) or transobturator tape (TOT) procedures using a synthetic polypropylene mesh with or without concomitant anterior colporrhaphy. All patients underwent preoperative videourodynamic studies, Valsalva leak point pressure (VLPP), and voiding efficiency (VE). The success rate, postoperative complications, overactive bladder symptoms, transvaginal urethrolysis, and repeat procedures were compared among different surgical procedures. Among the patients, PVS was performed in 251 (47.1%) patients and with colporrhaphy in 58 (10.9%), TOT in 174 (32.6%) and with colporrhaphy in 50 (9.4%). The success rate was 87.4% in the PVS group and 75.4% in the TOT group, with or without colporrhaphy (p = 0.001). Urethrolysis was performed in 4.7% of the patients, and repeat suburethral sling procedures were performed in 8.3%. The overall success rate was significantly lower in TOT group, either with high or low VLPP, or with high or low VE. The rate of persistent OAB was significantly higher in TOT group regardless of VLPP or VE, whereas patients with VE < 90% at baseline had a significantly higher rate of postoperative dysuria. TOT procedures had an inferior long-term success rate than PVS procedures for female SUI. Additionally, no differences in the success rate were observed between patients with different bladder functions, high or low VLPP, and high or low VE.

To Stage or Not to Stage? Direct-to-Implant Versus Staged Reconstruction for Implant-Based Breast Reconstruction

Abstract Goals/Purpose Implant-based breast reconstruction remains the common method of reconstruction after mastectomy in the US. An increasing number of centers are now offering direct-to-implant (DTI) breast reconstruction, avoiding staged reconstructions with tissue expander placement first. However, little is known regarding the need for revisions following DTI. In this study we sought to investigate short- and long-term complications and revisions following DTI versus staged reconstruction. Methods/Technique We retrospectively reviewed all patients who underwent bilateral nipple-sparing-mastectomies seeking implant-based breast reconstruction between September 2016 to September 2021. We extracted demographic and clinical information for the selected patients. Patients were divided in two cohorts: the DTI cohort, and the staged cohort. Baseline differences among the two groups were assessed by performing non-parametric statistical tests. Number of complications and revisions were assessed by employing chi-square. Logistic regression was then employed to adjust for possible confounders. Results/Complications During the study period, we identified 143 patients, 69 in the DTI cohort and 74 in the staged cohort. Patients in the staged cohort were more likely to have higher BMI (mean 26 kg/m2 versus 24.3 kg/m2 in the DTI cohort) and have undergone prior radiotherapy than those in the DTI cohort. No differences based on age, race/ethnicity or comorbidities were present. According to our analysis and within the follow up period time of average 21 months, the two cohorts had similar rates of minor and major short- and long-term surgical complications. After adjusting for potential confounding factors, the DTI group had a significantly higher rate of overall revisions (OR 2.73, 95% CI 1.23-6.07, p-value 0.01) and specifically revisions with implant exchange (0R 3.06, 95% CI 1.06-8.85, p-value 0.03). Most common reason for reason was asymmetry or contour deformity. However, the DTI cohort had significantly lower charges associated with their care during the follow up period (d=-100,178.14 US dollars, p-value=0.001). Complications rates were similar among the two groups. Conclusion An increasing number of patients are now interested in DTI breast reconstruction. According to the results of our study, DTI patients may have increased number of revisions but share similar rates of complications. DTI breast reconstruction is also associated with lower charges, even after accounting for the additional necessary revision procedures. Careful selection of patients for DTI and appropriate education on the need for revisions in the future is paramount.

No Difference in Revision Rates up to 10 years Following Total Hip Arthroplasty in Patients Who Had Prior Bariatric Surgery When Compared to Patients Who Had Class III Obesity: A Propensity Matched Analysis

BackgroundThere is no clear research showcasing bariatric surgery’s (BS’s) impact on long-term surgical complications following total hip arthroplasty (THA). Therefore, this study compared the 10-year cumulative incidence and risk of revision following THA in patients who underwent BS when compared to the general population and class III obesity patients who did not undergo BS. MethodsPatients who underwent elective THA from 2010 to 2021 were identified using an all-payer claims database. Patients who underwent BS prior to THA were separately matched to a control of the general population and those who had class III obesity (body mass index ≥40) by age, sex, Charlson Comorbidity Index, and diabetes using a 1:4 ratio. Kaplan-Meier analyses generated 10-year cumulative incidence rates, and a Cox proportional hazard ratio (HR) model generated HRs and 95% confidence intervals (CIs). ResultsWhen compared to the general control, patients who have a history of BS had an elevated 10-year risk of all-cause revision (HR 1.31, 95% CI: 1.16 to 1.47, P < .001), prosthetic joint infection (HR: 1.62, CI: 1.30 to 2.04; P < .001), mechanical loosening (HR: 1.20, CI: 1.01 to 1.44; P = .040), and dislocation/instability (HR: 1.35, CI: 1.09 to 1.68; P = .007). There was no difference in the 10-year risk of all-cause revision or other indications for revision in the BS cohort compared to the matched class III obesity cohort (P = .142). ConclusionsThose who underwent BS before THA had comparable 10-year revision rates when compared to those who had class III obesity and higher rates compared to the general population. This suggests BS may not reduce the 10-year surgical risks associated with obesity when compared to a class III obese surgical population.

Laparoscopic Gastrogastrostomy – An Alternative Procedure for Stenosis after Sleeve Gastrectomy

Abstract Introduction: Reflux symptoms associated with stenosis after laparoscopic sleeve gastrectomy can occur secondary to anatomical abnormality including mechanical stenosis and axial deviation, commonly occurring mid-sleeve. Treatment options include endoscopic intervention, including dilatation, stenting, myotomy, and surgical revision, with Roux-en-Y gastric bypass (RYGB) being preferred by many. In this case series, we report six patients who have undergone laparoscopic gastrogastrostomy (GG) for gastric stenosis and propose this as a possible surgical alternative for appropriately selected patients with symptomatic angularis stenosis. Patients and Methods: Medical records for six patients who underwent laparoscopic GG for treatment of persistent reflux symptoms due to angularis stenosis were reviewed. All patients were preoperatively investigated with endoscopy and abdominal three-dimensional computed tomography. Hiatal hernia and esophageal dilation were excluded. After further consultation, patients proceeded to laparoscopic GG. Results: Complete resolution of symptoms was reported in three of six patients, with Visick score 1, while the other three reported significantly improved symptoms. Postoperative body mass index remained similar to prerevision baseline. There were no postoperative complications. Conclusion: Revision to RYGB is effective for stenosis and reflux but can be challenging with the potential for long-term nutritional deficiencies and surgical complications. For patients with angularis stenosis, laparoscopic GG is a simpler revisional procedure that has shown adequate initial outcomes with no short or anticipated long-term complications in this case series. Patients with persisting symptoms could undergo subsequent gastric bypass if needed.

Spondylodiscitis instrumented fusion, a prospective case series on a standardized neurosurgical protocol with long term follow up

PurposeTo investigate the fusion construct properties, construct length, intervertebral prosthesis (IVP) selection, bone grafting methods, complications management, and follow-up outcomes of spondylodiscitis fusion. MethodThis case series was conducted in Al-Zahra University referral hospital from March 2016 to November 2021. All the surgery-eligible patients were enrolled. Those who did not participate or failed the neurosurgical intervention were excluded. A unified neurosurgical protocol was defined. After operation and follow-up, all variables were documented. IBM SPSS v.26 was used for data analysis. P-value ≤ 0.05 was considered significant. ResultNinety-two patients were reviewed in the final analysis with 65.2 % males. The mean age was 55.07 ± 14.22 years old. The most frequent level of pathology and surgery was the lumbar spine (48.9 %). Short and long constructs were almost equally used (57.6 and 42.4 %, respectively). Bone graft mixture was the dominant IVP (75 %). The most frequent persistent postoperative symptom was back pain (55.4 %), while the neurological deficits resolution rate was 76.7 %. The fusion rate was 92.3 %. Proximal junctional kyphosis incidence was 16.3 % and had a significant association with on-admission neurological symptoms, thoracic and thoracolumbar junction involvements (p < 0.05). Follow-up Oswestry disability index scores showed 44.6 % of the patients had mild or no functional disabilities. Advanced age, On-admission deficits, comorbidities, titanium cages, and poor fusion status were associated with poor functional outcomes and higher mortality rates (P < 0.05). ConclusionThe introduced neurosurgical protocol could effectively achieve acceptable SD treatment, spine stabilization, and fusion with low long-term surgical complications. Autologous bone graft mixture in comparison to titanium cages showed a higher fusion rate with a lower mortality rate. Patients with older age, neurological symptoms, and comorbidities are expected to experience less favorable clinical outcomes.

Obesity does not associate with 5-year surgical complications following anatomic total shoulder arthroplasty and reverse total shoulder arthroplasty.

Although obesity has been shown to increase the risk of short-term medical complications following total shoulder arthroplasty (TSA), evidence is lacking on the influence of obesity on longer-term surgical complications such as revision. The purpose of this study was to assess the association of increasing obesity with 2- and 5-year all-cause revision, periprosthetic joint infection (PJI), aseptic loosening, and manipulation under anesthesia (MUA) among patients undergoing reverse total shoulder arthroplasty (RTSA) or TSA. Patients who underwent RTSA or TSA with a minimum 5-year follow-up were identified in a national claims database (PearlDiver Technologies). Patients with obesity (body mass index [BMI]≥30) were compared to patients who are normal or overweight (18.5 ≤ BMI < 30). Those with obesity were further stratified to those with class I or II obesity (30 ≤ BMI < 40) and those with class III obesity (BMI ≥ 40). Outcomes for comparison included all-cause revision, PJI, aseptic loosening, and MUA within 2 or 5 years. These cohorts were compared using univariate and multivariable analysis. Patients with obesity had no significant difference in any surgical complication within 2 or 5 years for both those who underwent TSA or RTSA. After stratifying by class I or II obesity and class III obesity, there was still no significant difference in surgical complications with 2 or 5 years for both TSA patients and RTSA patients. Obesity, when other major comorbidities are controlled for, was not associated with increased risk of long-term surgical complications after shoulder replacement surgery.

Long-Term Surgical Outcomes and Possible Postoperative Complication with Severe Corneal Endothelial Cell Loss After Trabeculectomy for Cytomegalovirus-Associated Anterior Uveitis with Secondary Glaucoma

ABSTRACT Purpose We assess long-term surgical outcomes after an initial trabeculectomy for cytomegalovirus-associated anterior uveitis with secondary glaucoma (CMV-SG). Methods We retrospectively reviewed the medical records of 16 eyes of 15 patients with CMV-SG and 157 eyes of 157 patients with primary open-angle glaucoma. The average follow-up period was approximately 3 years. Surgical success was defined as intraocular pressure (IOP) below 18 mmHg and at least 20% lower than baseline. Results Kaplan–Meier survival analysis revealed that bleb survival rates were not significantly different in the CMV-SG and POAG groups (P = 0.75). Bullous keratopathy occurred in 2 of 16 eyes with CMV-SG postoperatively but did not occur in the POAG group. The corneal endothelial cell density decreased by 34.2 ± 22.7% in the CMV-SG group during an average follow-up period of 2.7 ± 2.0 years. Conclusion Trabeculectomy effectively controlled IOP in CMV-SG, but attention must be paid to corneal endothelial cell loss.

Comparison of clinical outcomes between laparoscopic orchiopexy and open orchiopexy in the treatment of palpable undescended testes.

To compare the clinical effects of laparoscopic orchiopexy (LO) and open orchiopexy (OO) in the treatment of palpable undescended testes. Seventy-six children with palpable undescended testes treated in Zaozhuang Municipal Hospital from June 2019 to January 2021 were selected in this observational retrospective study. Patients were grouped according to their different surgical methods, 33 patients received OO (Open-group) and 43 patients received LO (Laparoscopic-group). The clinical outcomes of the two groups were compared, including surgical-related indicators, near and long-term surgical complications and postoperative testicular growth. Operation time, intraoperative bleeding, first ambulation time and hospitalization time in the Laparoscopic-group were lower than those in the Open-group (p<0.05). The short-term complication rate in the Laparoscopic-group was lower than that in the Open-group (2.27% vs 15.15%; p<0.05), but the long-term complication rate in the Laparoscopic-group was not significantly different from the Open-group (4.65% vs 3.03%; p>0.05). Follow-up was up to 18 months post-operation, with the rate of testicular growth (97.67% vs 96.97%; p>0.05) and testicular volume (0.59 ± 0.14ml vs 0.58 ± 0.12ml p>0.05) not significantly different between the Laparoscopic-group or Open-group respectively. LO is as clinically effective as OO in the treatment of palpable undescended testes, however, shorter operation time, less intraoperative bleeding and rapid recovery time have been noted with LO.

Direct Bypass Surgery for Moyamoya and Steno-occlusive Vasculopathy: Clinical Outcomes, Intraoperative Blood Flow Analysis, Long-term Follow-up, and Long-term Bypass Patency in a Single Surgeon Case Series of 162 Procedures

Cerebral extracranial-intracranial (EC-IC) direct bypass is a commonly used procedure for the treatment of cerebral hypoperfusion secondary to chronic steno-occlusive vasculopathy. We sought to determine clinical outcomes, intraoperative blood flow analysis, long term follow up, and long term patency rates from a single surgeon's series of direct cerebral bypass for moyamoya disease, moyamoya syndrome, and steno-occlusive disease. We reviewed clinical, demographic, operative and neuroimaging records for all patients who underwent a direct EC-IC bypass by the senior author between August 1999 and November 2020. Primary outcomes analyzed were functional long-term outcomes (by modified Rankin score [mRS]), surgical complications, and short-term and long-term bypass patency. A total of 162 revascularization procedures in 124 patients were performed. Mean clinical follow up time was 2 years 11 months. The combined immediate and long term postoperative stroke and/or intracerebral hemorrhage rate was 6.2%. There were 17 bypasses (10%) that were found to be occluded at long-term follow-up, all but one were asymptomatic. Long-term graft occlusion was correlated with presence of complete collateralization on preoperative angiography but not cut flow index (CFI). Overall, patients had a significant clinical improvement with a mean mRS score 1.8 preoperatively and 1.2 postoperatively. In our consecutive series of patients treated with direct EC-IC cerebral bypass, there was significant improvement in functional outcome as measured by the mRS. The long term patency rate was 90%. There was a statistically significant correlation between complete or incomplete angiographic collateralization patterns and long-term bypass occlusion. There was no correlation between bypass type, clinical syndrome, or CFI and long-term occlusions. The role of bypass surgery and the need for surgical expertise remain strong in the treatment of moyamoya variants and a select group of atherosclerotic steno-occlusive patients.

Laparoscopic vs Open Distal Gastrectomy for Locally Advanced Gastric Cancer

The long-term safety of laparoscopic distal gastrectomy for locally advanced gastric cancer (AGC) remains uncertain given the lack of 5-year follow-up results. To compare the 5-year follow-up results in patients with clinically AGC enrolled in the Korean Laparoendoscopic Gastrointestinal Surgery Study (KLASS)-02 randomized clinical trial who underwent laparoscopic or open distal gastrectomy. The KLASS-02, a multicenter randomized clinical trial, showed that laparoscopic surgery was noninferior to open surgery for patients with locally AGC. The present study assessed the 5-year follow-up results, including 5-year overall survival (OS) and relapse-free survival (RFS) rates and long-term complications, in patients enrolled in KLASS-02. From November 21, 2011, to April 29, 2015, patients aged 20 to 80 years diagnosed preoperatively with locally AGC were enrolled. Final follow-up was on June 15, 2021. Data were analyzed June 24 to September 9, 2021. Patients were treated with R0 resection either by laparoscopic gastrectomy or open gastrectomy as the full analysis set of the KLASS-02 trial. Five-year OS and RFS rates, recurrence patterns, and long-term surgical complications were evaluated. This study enrolled a total of 1050 patients. A total of 974 patients were treated with R0 resection; 492 (50.5%) in the laparoscopic gastrectomy group (mean [SD] age, 59.8 [11.0] years; 351 men [71.3%]) and 482 (49.5%) in the open gastrectomy group (mean [SD] age, 59.4 [11.5] years; 335 men [69.5%]). In patients who underwent laparoscopic and open distal gastrectomy, the 5-year OS (88.9% vs 88.7%) and RFS (79.5% vs 81.1%) rates did not differ significantly. The most common types of recurrence were peritoneal carcinomatosis (73 of 173 [42.1%]), hematogenous metastases (36 of 173 [20.8%]), and locoregional recurrence (23 of 173 [13.2%]), with no between-group differences in types of recurrence at each cancer stage. The correlation between 3-year RFS and 5-year OS at the individual level was highest in patients with stage III gastric cancer (ρ = 0.720). The late complication rate was significantly lower in the laparoscopic than in the open surgery group (32 of 492 [6.5%] vs 53 of 482 [11.0%]). The most common type of complication in both groups was intestinal obstruction (13 of 492 [2.6%] vs 24 of 482 [5.0%]). The 5-year outcomes of the KLASS-02 trial support the 3-year results, which is the noninferiority of laparoscopic surgery compared with open gastrectomy for locally AGC. The laparoscopic approach can be recommended in patients with locally AGC to achieve the benefit of low incidence of late complications. ClinicalTrials.gov Identifier: NCT01456598.

Preoperative chemoradiotherapy with capecitabine and triweekly oxaliplatin versus capecitabine monotherapy for locally advanced rectal cancer: a propensity-score matched study

BackgroundDistant metastasis has been the main failure pattern for locoregionally advanced rectal cancer (LARC) patients, and intensified neoadjuvant chemotherapy has become a popular research topic. The present study aimed to compare the survival outcomes, acute toxicities and surgical complications in LARC patients who received preoperative chemoradiotherapy with triweekly oxaliplatin and capecitabine (triweekly XELOX) or capecitabine.Methods: Between 2007 and 2017, patients with clinically staged II-III rectal cancer who were treated with preoperative chemoradiotherapy using either triweekly XELOX (oxaliplatin 130 mg/m2 plus capecitabine 825 mg/m2) or capecitabine were included. Variables potentially influencing chemotherapy treatment selection were used to generate propensity scores (PS). The association between chemotherapy regimens and survival endpoints, including distant metastasis-free survival (DMFS), overall survival (OS) and disease-free survival (DFS), were evaluated and adjusted with PS. The acute toxicities and surgical complications were also compared.ResultsA total of 810 patients were included in the analysis; 277 (34.2%) patients received triweekly XELOX, and 533 (65.8%) received capecitabine. The pathological complete response (pCR) rates were 20.2 and 19.9% (P = 0.912) for the groups treated with triweekly XELOX and capecitabine, respectively. The 5-year DMFS, OS and DFS with triweekly XELOX versus capecitabine were 75.6% vs. 77.6% (P = 0.555), 79.2% vs. 83.3% (P = 0.101), and 69.9% vs. 73.7% (P = 0.283), respectively. Triweekly XELOX was not associated with an increased risk of severe toxicity during chemoradiotherapy, but it increased the risk of postoperative complications compared to capecitabine. After PS adjustment, the differences between the two groups remained insignificant in pCR rate, survival outcomes, and acute toxicities, and the difference in surgical complications disappeared.ConclusionsTriweekly XELOX or capecitabine concurrent with neoadjuvant radiotherapy leads to similar long-term survival outcomes, acute toxicities and surgical complications in LARC patients.

Outcomes of Pars Plana Vitrectomy and 4-Point Sutured Scleral Fixation of Akreos AO60 Intraocular Lens in Clinical Settings: A Case Series

To determine the long-term anatomic outcomes and surgical complications of pars plana vitrectomy (PPV) and 4-point Gore-Tex-sutured Akreos AO60 intraocular lens (IOL) scleral fixation. Retrospective, multicenter, multisurgeon case series. Ninety-seven patients in tertiary eye care centers. The patients underwent PPV and intraocular fixation of the Akreos AO60 IOL using Gore-Tex CV-8 sutures between January 2015 and April 2020. The inclusion criteria were aphakia, no capsular support, and a minimal 1 year of follow-up. Uncorrected visual acuity (VA), complication rates or types, and refraction. Data from 101 eyes of the 97 patients were analyzed (mean follow-up duration, 33.4 months; range, 12-62 months). The mean ± standard deviation uncorrected logarithm of the minimum angle of resolution VA improved from 1.04 ± 0.73 (20/200 Snellen equivalent) before surgery to 0.66 ± 0.65 (20/80) at 6 months after surgery (P < 0.001). The most prevalent complications included hypotony (12.9%), ocular hypertension (12.9%), corneal edema (8.9%), cystoid macular edema (6.9%), and vitreous hemorrhage (5.9%). Refraction was measured between 3 and 6 months after surgery, and 61.8% of the patients had spherical equivalent of ± 2.0 diopters. Most complications occurred in the first postoperative month and resolved spontaneously or with medical treatment. The results demonstrated that this surgical technique is well tolerated by the eyes, with a low complication rate in the long term. The rates of IOL opacification were infrequent for up to 62 months of follow-up.

Predictors of Long-Term Complications of Femoropopliteal Bypass with Autovenous Graft

INTRODUCTION: Atherosclerotic lesion of lower limb arteries often occurs with the development of chronic and later with critical ischemia of the lower limbs. Revascularization in these conditions has always been at the center of attention of vascular surgeons worldwide.&#x0D; AIM: To analyze long-term complications after femoropopliteal bypass (FPB) with the autovenous graft.&#x0D; MATERIALS AND METHODS: This retrospective open study was conducted in Scientific the Research Institute Regional Clinical Hospital No. 1 named after Professor S. V. Ochapovsky (Krasnodar) in the period from January 10, 2016, to December 25, 2019, and included 464 patients who underwent FPB with venous autograft. The following autovenous conduits were used: n = 266, reverse vein (great saphenous vein (GSV)); n = 59, autovein (GSV) prepared in situ; n = 66, autovein (GSV) prepared ex situ; and n = 73, veins of an upper limb. The long-term follow-up period was 16.6 10.3 months.&#x0D; RESULTS: During the postoperative hospital period, single cases of lethal outcome and myocardial infarction were noted. No ischemic strokes were recorded. Shunt thrombosis developed in 4.5% of the patients, and 2.1% required limb amputation. Postoperative wound revision caused by bleeding was performed in 1.7% of the cases. In the remote follow-up period, adverse cardiovascular events were noted in every fifth patient (21.8%). Shunt thrombosis was diagnosed in 17.4% of cases, and limb amputation was performed in 5.1% of the cases. To identify the factors for poor prognosis, the whole sample was divided to two groups: group 1 (n = 366) included those without long-term complications and group 2 (n = 99) comprised patients with long-term complications. Using the odds ratio (OR), the following predictors of adverse cardiovascular events were identified: degree I obesity (р 0.0001; OR = 3.24; 95% confidence interval (CI) = 1.935.43), degree II obesity (р = 0.0005; ОR = 4.84; 95% CI = 1.7113.67), and stage IIB chronic lower limb ischemia (CLLI) (р = 0.0006; ОR = 2.24; 95% CI = 1.423.52). Protective factors were postinfarction cardiosclerosis (р = 0.04; ОR = 0.51; 95% CI = 0.270.95), excessive body mass (р = 0.01; ОR = 0.56; 95% CI = 0.350.88), and stage IV CLLI (р = 0.01; ОR = 0.53; 95% CI = 0.320.86).&#x0D; CONCLUSIONS: FPB with venous autograft is characterized by a low frequency of complications in the hospital and long-term follow-up periods, making this technique a method of choice for the open surgical treatment of patients with extended atherosclerotic lesion of the superficial femoral artery. Predictors of adverse cardiovascular events in the long-term period are degree I obesity, degree II obesity, and stage IIB CLLI. Protective factors against the development of long-term surgical complications are postinfarction cardiosclerosis, overweight, and stage IV CLLI. The presented results should be considered when constructing stratification risk scales for adverse cardiovascular events in patients who underwent FPB. Precision management of patients with identified predictors of complications will allow the reduction of the risks for the development of these conditions and increase long-term survival free from shunt thrombosis and limb amputation.

Celiac Disease and Bariatric Surgery: A Systematic Review of Current Literature

Background: Celiac disease (CD) is a clinical entity increasingly recognized in the severe obese population and its impact on outcomes following bariatric surgery is not currently understood. We aimed to systematically review the nutritional and clinical outcomes for patients with obesity and CD following bariatric surgery. Methods: Systematic search of MEDLINE, Embase, Scopus, and Web of Science was conducted in September 2021. Study followed PRISMA guidelines. Studies evaluating adult patients with CD undergoing bariatric surgery were included. Outcomes were descriptive due to limited studies. Results: Our literature review produced 9 studies with 152 patients. The weighted mean age of included patients was 44.2 years (±9.55 years) and 98% (n = 149) were female. Patients diagnosed with CD post-operatively appear to experience substantial perioperative and nutritional complications following bariatric surgery. However, pre-operative diagnosis may allow patient optimization and current studies suggest similar bariatric surgery outcomes can be achieved in these patients when the diagnosis is known. However, this study also highlights a scarcity of evidence evaluating the rate of CD and outcomes for these patients after bariatric surgery. Conclusion: Current literature lacks quality, comparative studies investigating the short- and long-term surgical complications and nutritional outcomes of bariatric surgery within patients who have co-diagnoses of obesity and CD. Despite these limitations, our group recommends pre-operative CD screening in patients experiencing either classical GI symptoms of CD including diarrhea, steatorrhea, bloating, or undifferentiated abdominal pain.

Pediatric Liver Transplantation: Long-Term Follow-Up Issues.

Pediatric liver transplant is an established life-saving procedure for children with end-stage liver diseases, achieving excellent graft and patient survival but with effects on quality of life and psychological welfare in the long-term. With the natural increase in the number of pediatric transplant patients becoming adults, it is essential to successfully plan and manage issues affecting late outcomes in the vulnerable pediatric transplant population. This study offers an overview of the long-term surgical complications, the consequences of immunosuppression (such as posttransplant diabetes, hypertension, cardiovascular disease, and renal dysfunction), and the infection and malignancy risks. Finally, because quality of life is now an inclusive measurement of patient satisfaction, guidance on how to facilitate the transition to adulthood, empowering transplant recipients, is also provided.

Surgical outcomes in survivors of childhood cancer undergoing thyroidectomy: A single-institution experience.

Childhood cancer survivors (CCS) are at increased risk for thyroid disease, and many require definitive management with thyroid surgery. Despite this, there is limited evidence on surgical outcomes among CCS. We sought to evaluate postoperative outcomes at our institution among CCS undergoing thyroid surgery compared to patients without a history of primary childhood malignancy. Medical records were reviewed for 638 patients treated at the Children's Hospital of Philadelphia Pediatric Thyroid Center between 2009 and 2020. Rates of surgical complications, including recurrent laryngeal nerve (RLN) paralysis and hypoparathyroidism, among CCS were compared to patients with sporadic/familial thyroid cancer, Graves' disease, and other benign thyroid conditions. Operative time and intraoperative parathyroid hormone levels were also evaluated. There were no significant differences in long-term surgical complication rates, such as permanent RLN paralysis and hypoparathyroidism, between CCS and patients without a history of primary childhood malignancy (all p>.05). For all surgical outcomes, there were no significant differences in complication rates when CCS were compared to those undergoing surgery for sporadic/familial thyroid cancer or Graves' disease (all p>.05). CCS with benign final pathology had significantly higher rates of transient hypoparathyroidism compared to patients with benign thyroid conditions (p<.001). Our study suggests that CCS are not at higher risk of long-term complications from thyroid surgery when treated by high-volume surgeons within a multidisciplinary team.

Challenges in Diagnosis and Prevention of Iatrogenic Endometriosis as a Long-Term Surgical Complication after C-Section.

Endometriosis is a gynecological condition caused by the development of endometrial tissue outside the uterine cavity. Naturally, it commonly occurs at locations such as the ovaries and pelvic peritoneum. However, ectopic endometrial tissue may be discovered outside of the typical sites, suggesting the possibility of iatrogenic seeding after gynecological operations. Based on this hypothesis, we developed a study aiming to establish the root cause of atypical implantation of endometrial foci, as the main end point, and to determine diagnostic features and risk factors for this condition, as a secondary target. The research followed a retrospective design, including a total of 126 patients with endometriosis who met the inclusion criteria. A group of 71 patients with a history of c-section was compared with a control group of patients with endometriosis and no history of c-section. Endometriosis that developed inside or in close proximity to surgical incisions of asymptomatic patients before surgical intervention was defined as iatrogenic endometriosis. Compared with patients who did not have a c-section, the c-section group had significantly more minimally invasive pelvic procedures and multiple adhesions and endometriosis foci at intraoperative look (52.1% vs. 34.5%, respectively 52.1% vs. 29.1%). The most common location for endometriosis lesions in patients with prior c-section was the abdominal wall (42.2% vs. 5.4%), although the size of foci was significantly smaller by size and weight (32.2 mm vs. 34.8 mm, respectively 48.6 g vs. 53.1 g). The abdominal wall endometriosis was significantly associated with minimally invasive pelvic procedures (correlation coefficient = 0.469, p-value = 0.001) and c-section (correlation coefficient = 0.523, p-value = 0.001). A multivariate regression analysis identified prior c-section as an independent risk factor for abdominal wall endometriosis (OR = 1.85, p-value < 0.001). We advocate for strict protocols to be implemented and followed during c-section and minimally invasive procedures involving the pelvic region to ensure minimum spillage of endometrial cells. Further research should be developed to determine the method of abdominal and surgical site irrigation that can significantly reduce the risk of implantation of viable endometrial cells. Understanding all details of iatrogenic endometriosis will lead to the development of non-invasive disease diagnosis and minimally invasive procedures that have the potential to reduce postoperative complications.

Comparison of long-term results of trabeculectomy and phacotrabeculectomy in patients with pseudoexfoliation glaucoma and primary open-angle glaucoma: a single-center study.

To evaluate long-term surgical success and complications in pseudoexfoliation glaucoma (PEXG) and primary open-angle glaucoma (POAG) after trabeculectomy or phacotrabeculectomy. 96 PEXG eyes and 114 POAG eyes who underwent primary trabeculectomy and phacotrabeculectomy were retrospectively evaluated considering intraocular pressure (IOP), the number of glaucoma medications, surgical success, and rate of complications. Two success criteria were used: Complete success comprised IOP of 5-18mmHg and 20% reduction of baseline IOP without medication. Qualified success comprised IOP of 5-18mmHg and 20% reduction of baseline IOP irrespective of medication. Success rates in PEXG and POAG groups, trabeculectomy and phacotrabeculectomy groups, and four groups divided according to surgery and etiology were analyzed via Kaplan-Meier survival analysis. The complete and qualified success were not different between PEXG and POAG groups. The qualified success curves show a similar pattern among the four groups throughout the follow-up of 1,2,3,5,7 and 9years. Baseline IOP and the number of medications were similar in all four groups (p = 0.275 and p = 0.209, respectively). IOP levels and the number of medications were not statistically different between the four groups during the follow-up of 2,5 and 7years. The total number of complications and interventions were similar between PEXG and POAG groups (p = 0.258). Phacotrabeculectomy is an effective procedure as trabeculectomy with similar surgical success rates and few surgical complications when it comes to treating PAOG and PEXG patients. Both approaches resulted in similar postoperative IOP levels and medication numbers in both groups.

Carbon Monoxide in Pancreatic Islet Transplantation: A New Therapeutic Alternative to Patients With Severe Type 1 Diabetes Mellitus.

Pancreatic islet transplantation is a minimally invasive procedure to replace β-cells in a subset of patients with autoimmune type 1 diabetic mellitus, who are extremely sensitive to insulin and lack counter-regulatory measures, and thereby increasing their risk of neuroglycopenia and hypoglycemia unawareness. Thus, pancreatic islet transplantation restores normoglycemia and insulin independence, and prevents long-term surgical complications associated with whole-organ pancreas transplantation. Nonetheless, relative inefficiency of islet isolation and storage process as well as progressive loss of islet function after transplantation due to unvoidable islet inflammation and apoptosis, hinder a successful islet transplantation. Carbon monoxide (CO), a gas which was once feared for its toxicity and death at high concentrations, has recently emerged as a medical gas that seems to overcome the challenges in islet transplantation. This minireview discusses recent findings about CO in preclinical pancreatic islet transplantation and the underlying molecular mechanisms that ensure islet protection during isolation, islet culture, transplantation and post-transplant periods in type 1 diabetic transplant recipients. In addition, the review also discusses clinical translation of these promising experimental findings that serve to lay the foundation for CO in islet transplantation to replace the role of insulin therapy, and thus acting as a cure for type 1 diabetes mellitus and preventing long-term diabetic complications.

Comparison of Acute and Chronic Surgical Complications Following Robot-Assisted, Laparoscopic, and Traditional Open Radical Prostatectomy Among Men in Taiwan

Few studies have evaluated long-term surgical complications in patients with prostate cancer (PC) who receive open radical prostatectomy (ORP), laparoscopic radical prostatectomy (LRP), or robot-assisted radical prostatectomy (RARP). To examine the perioperative and postoperative surgical complications among patients with PC who underwent ORP, LRP, or RARP. This cohort study included patients who received a diagnosis of resectable PC and underwent RP between January 1 and December 31, 2015. Participants were enrolled in the Taiwan Cancer Registry. The index date was the date of surgery, and the follow-up duration was the period from the index date to December 31, 2018. Data analysis was performed in September 2020. ORP, LRP, or RARP. Two multivariate mixed models accounting for hospital clusters were fitted to ascertain the association of RARP with treatment outcomes (ie, hospital stay, blood transfusion, postoperative pain, erectile dysfunction, urinary incontinence, and hernia); general linear regression models were used for continuous outcomes, the amount of blood transfused, and hospital stay, and logistic regression models were used for analyzing postoperative outcomes and surgical complications. Of the 1407 patients included in this study, 315 (22.4%) received ORP (mean [SD] age, 66.4 [6.8] years), 276 (19.6%) received LRP (mean [SD] age, 66.8 [6.4] years), and 816 (58.0%) received RARP (mean [SD] age, 66.1 [6.7] years). Mean (SD) follow-up in the full cohort was 36.7 (4.6) months. No statistically significant differences were observed in age, clinical tumor stage, pathological tumor stage, Gleason score, Gleason grade group, preoperative prostate-specific antigen concentration, D'Amico risk classification, and hospital level. A shorter hospital stay was observed for patients undergoing RARP vs those undergoing ORP (mean [SE] difference, -1.64 [0.22] days; P < .001) and LRP (mean [SE] difference, -0.57 [0.23] days; P = .01). Patients undergoing RARP had lower odds of receiving a blood transfusion (RARP vs ORP: adjusted odds ratio [aOR], 0.25; 95% CI, 0.17-0.36; RARP vs LRP: aOR, 0.58; 95% CI, 0.37-0.91). For postoperative pain, RARP was associated with a decrease in the odds of moderate to severe postoperative pain for as long as 12 weeks compared with both ORP and LRP (eg, RARP vs LRP at week 12: aOR, 0.40; 95% CI, 0.19-0.85; P = .02). The aORs for RARP vs those for ORP and LRP in the third year after RP were, for erectile dysfunction, 0.74 (95% CI, 0.45-0.92) and 0.60 (95% CI, 0.36-0.98), respectively; for urinary incontinence, 0.93 (95% CI, 0.65-0.99) and 0.60 (95% CI, 0.42-0.86), respectively; and for hernia, 0.51 (95% CI, 0.31-0.84) and 0.82 (95% CI, 0.46-0.92), respectively. In this study, undergoing RARP was associated with fewer acute and chronic postoperative complications than undergoing ORP or LRP.
