Can the presence of SLAP-5 lesions be predicted by using the critical shoulder angle in traumatic anterior shoulder instability?

OBJECTIVE: Although SLAP-5 lesions are associated with recurrent dislocations, their causes and pathomechanisms have not been fully elucidated. This study aimed to investigate the association between SLAP-5 lesions and scapular morphology in traumatic anterior shoulder instability (ASI). We hypothesized that there may be a relationship between SLAP-5 lesions and scapular morphology in traumatic ASI patients. MATERIALS AND METHODS: The study included 74 patients with isolated Bankart lesions and 69 with SLAP-5 lesions who underwent arthroscopic labral repair for ASI. Critical shoulder angle (CSA) was measured on the roentgenograms, while glenoid inclination (GI) and glenoid version (GV) were measured on magnetic resonance imaging (MRI) by two observers in two separate sessions blinded to each other. Both groups were compared in terms of CSA, GI, and GV. RESULTS: The mean ages of Bankart and SLAP-5 patients were 28.4±9.1 and 27.9±7.7 (P=0.89), respectively; their mean CSA values were 33.1°±2.6° and 28.2°±2.4°, respectively (P<0.001). The ROC analysis's cut-off value was 30.5°, with 75.0% sensitivity and 76.7% specificity (AUC = 0.830). SLAP-5 lesions were more common on the dominant side than isolated Bankart lesions (P=0.021), but no difference was found between the groups in terms of GI and GV (P=0.334, P=0.081, respectively). CONCLUSIONS: In ASI, low CSA values appeared to be related to SLAP-5 lesions, and the cut-off value of CSA for SLAP lesion formation was 30.5° with 75.0% sensitivity and 76.7% specificity. Scapula morphology may be related to the SLAP-5 lesions, and CSA can be used as an additional parameter in provocative diagnostic tests and medical imaging techniques for the detection of SLAP lesions accompanying Bankart lesions. LEVEL OF EVIDENCE: III retrospective case-control study.

Management of the staple line bleeding in laparoscopic sleeve gastrectomy: monopolar cautery versus oversewing.

OBJECTIVE: Staple line bleeding control (SLBC) after laparoscopic sleeve gastrectomy (LSG) is a serious problem. Cauterization alone is generally not preferred because of concerns about weakening the staple line. The aim of this study was to compare the suturing and monopolar cauterization methods for SLBC in LSG. METHODS: 212 patients were divided into two groups as cautery and suture groups. Demographic characteristics, intraoperative, and post-operative results were analyzed. RESULTS: Post-operative complications were seen in seven patients, four of them staple line bleeding (three patients were in the cautery group and one patient was in the suture group), and three of them leakage (all patients were in the suture group) from the staple line. There was no significant difference between the groups in terms of staple line bleeding (p = 0.35), staple line leakage (p = 0.09), blood loss (p = 0.12), intraoperative complications (p = 0.16), post-operative hemoglobin decrease (p = 0.63), and length of hospital stay (p = 0.35), but the operation time was longer in the suture group. CONCLUSION: This is the first study in literature comparing monopolar cauterization with another technique. Monopolar cauterization can be used for SLBC in LSG. It is a safe and efficient method as well as inexpensive.

OBJETIVO: El control del sangrado de la línea de grapas (SLBC) después de la gastrectomía en manga laparoscópica(LSG) es un problema grave. Generalmente, no se prefiere la cauterización sola debido a preocupaciones sobre el debilitamiento de la línea de grapas. El objetivo de este estudio fue comparar los métodos de sutura y cauterización monopolar para SLBC en LSG. MÉTODOS: 212 pacientes fueron divididos en 2 grupos de cauterización y sutura. Se analizaron las características demográficas, los resultados intraoperatorios y posoperatorios. RESULTADOS: Se observaron complicaciones posoperatorias en siete pacientes, cuatro de ellos sangrado en la línea de grapas (tres pacientes estaban en el grupo de cauterización, un paciente en el grupo de sutura) y tres de ellos fuga (todos los pacientes estaban en el grupo de sutura) del línea de grapas. No hubo diferencia significativa entre los grupos en términos de sangrado de la línea de grapas (p = 0.35), fuga dela línea de grapas (p = 0.09), pérdida de sangre (p = 0.12), complicaciones intraoperatorias (p = 0.16), disminución de hemoglobina postoperatoria (p = 0.63), duración dela estancia hospitalaria (p = 0.35), pero el tiempo de operación fue mayor en el grupo de sutura. CONCLUSIÓN: Este es el primer estudio que compara la cauterización monopolar con otra técnica. La cauterización monopolar se puede utilizar para SLBC en LSG. Es un método seguro, eficaz y económico.

Can revision of RYGB to sleeve gastrectomy be a solution to inadequate weight loss treatment?

We aimed to discuss the weight loss success of the revision of RYGB to sleeve gastrectomy (SG). Between January 2019 and June 2020, four patients' files were analyzed retrospectively. Post-RYGB mean minimal BMI was 27.4 ± 9.47 kg/m², before SG the mean BMI was 43.41 ± 4.16 kg/m2. Post-operative gastric fistula developed in two patients. The mean follow-up time after revision surgery was 17.25 ± 6.89 months, mean excess weight loss (EWL) was 74.77 ± 8.94%, and mean BMI was 32.65 ± 2.9 kg/m2. Despite high rate of major complications, revision of RYGB to SG is successful in weight loss and resolving certain complications of RYGB.

Nuestro objetivo era discutir el éxito en la pérdida de peso de la revisión de BGYR a gastrectomía en manga (SG). Entre enero de 2019 y junio de 2020, se analizaron retrospectivamente los archivos de cuatro pacientes. El IMC mínimo medio post BGYR fue 27.4 ± 9.47 kg/m², antes de SG el IMC medio fue 43.41 ± 4.16 kg/m2. En dos pacientes se desarrolló una fístula gástrica posoperatoria. El tiempo medio de seguimiento después de la cirugía de revisión fue de 17.25 ± 6.89 meses, la pérdida media de exceso de peso (PEP) fue de 74.77 ± 8.94% y el IMC medio fue de 32.65 ± 2.9 kg/m2. A pesar de la alta tasa de complicaciones mayores, la revisión de BGYR a SG tiene éxito en la pérdida de peso y la resolución de ciertas complicaciones de BGYR.

Is It Possible to Estimate the Liver Left Lobe Volume Using Preoperative Data Before Bariatric Surgery?

PURPOSE: Retraction of the left lobe of the liver (LLL) is an important step in bariatric surgical procedures. A good liver retraction will both facilitate the operation and reduce complications. The aim of the study is to identify patients with large LLL with preoperative anthropometric and laboratory data, and to reveal complications due to large LLL. MATERIALS AND METHODS: The data of 245 patients who underwent bariatric surgery in our department between April 2019 and March 2021 were retrospectively analyzed. The patients were divided into two groups according to the visibility of the caudate lobe of the liver, the left diaphragmatic artery-vein, and the fat pad on the esophagus after liver retraction. RESULTS: Univariate analyses revealed significant differences in BMI, waist and hip circumferences, TG, DM, and HbA1c values, but only BMI (p = 0.001) and the presence of DM (p = 0.017) were found to be independent predictors of LLL size. BMI ≥ 42.1 kg/m2 indicates the size of LLL with 83% sensitivity and 49% specificity. Retractor-related complications were significantly higher in the large LLL group (p = 0.036). There was no difference between the two groups in terms of complications related to trocar insertion (p = 0.014) and postoperative liver enzyme levels (p = 0.714). The operation time (laparoscopic sleeve gastrectomy [LSG]; p = 0.021) (laparoscopic Roux-N-Y gastric bypass [LRYGB]; p = 0.020) and the amount of bleeding (LSG; p < 0.001) (LRYGB; p = 0.011) are higher in patients with large LLL. CONCLUSION: Large LLL can be predicted and complications may be reduced with the help of preoperative data.

The impact of splenectomy on human lipid metabolism.

Background: Splenectomy impacts hematological, immunological, and metabolic functions of the patient. Since our understanding of its metabolic effects, in particular effects on lipid metabolism, is limited, this study aims to investigate the effects of splenectomy on lipid metabolism. Methods: The data from 316 patients undergoing splenectomy between 2009 and 2019 were retrospectively analyzed. Thirty-eight patients whose serum lipid values were measured both preoperatively and 1 year after surgery were included in this study. Results: Significantly higher levels of total cholesterol, low-density lipoprotein (LDL), and non-high-density lipoprotein (HDL) lipid profile were found in the postsplenectomy measurements. However, no significant differences were recorded in levels of triglyceride, HDL, or very-LDL. Conclusion: We determined that splenectomy does impact lipid metabolism, and that the metabolic effects of splenectomy should further be investigated.

Splenic surgery: a ten years experience of a tertiary center in Turkey.

AIM: Splenectomy has been performed for various indications. In this study, we aimed to present the experience of a tertiary center on splenic surgery and analyze what has changed in the last 10 years. MATERIAL AND METHODS: Three hundred and sixteen patients who underwent splenic surgery were enrolled in the study. Demographic data, comorbidities, American Society of Anesthesiologists score, indications, operation type, postoperative complications, and mortality were analyzed retrospectively. RESULTS: The most common indication was traumatic splenic injury. Immune thrombocytopenic purpura (ITP) and gastric cancer were the second and third. Splenectomy was performed on 300 (94.9%) patients. Splenorrhaphy, partial splenectomy, and splenopexy were the other procedures performed. Postoperative complications occurred in almost onethird of the patients (n=118, 37.3%). Most of them were grade 5 according to the Clavien-Dindo classification. CONCLUSIONS: Splenectomy has become a less preferred treatment option with the development of non-operative management in splenic trauma, medical treatments for hematological diseases, and a better understanding of the immune, hematological and metabolic functions of the spleen. In the future, minimally invasive and spleen-sparing surgeries will be performed more frequently for patients who need splenectomy even for those with trauma. KEY WORDS: Cyst, Hematology, Laparoscopy, Sepsis, Splenectomy, Trauma.

Galectin-3 levels and inflammatory response in patients undergoing bariatric surgery.

PURPOSE: Obesity, a low-grade systemic inflammatory disease, causes inflammation in metabolic tissues. Galectin-3(Gal-3) is one of the lectin molecules involved in inflammatory processes. We evaluated the possible relationship between Gal-3 level and the metabolic inflammatory process before and after obesity surgery. METHODS: One hundred participants were included in the study and classified as normal weight, overweight, Class I, II, and III obese. Class III obese group underwent bariatric surgery and evaluated in the 3rd and 6th months after surgery. Glucose, insulin, glycated hemoglobin A1c (HbA1c), homeostatic model assessment of insulin resistance (HOMA-IR), high sensitivity C-reactive protein (hsCRP), Gal-3, interleukin (IL)-6, IL-10, adiponectin, and leptin levels were determined. RESULTS: Gal-3 levels were higher in Class III obese compared to the normal weight group. Postoperative leptin and hsCRP levels were decreased significantly, but the decrease in IL-6 and Gal-3 levels were not significant. Postoperative increased adiponectin and IL-10 levels were significant. Gal-3 was found significantly higher in insulin resistant group. The correlation between Gal-3 with BMI, adiponectin, leptin, hsCRP levels, and HOMA-IR was found weak. CONCLUSION: These findings might support the fact that Gal-3 is one of the molecules involved in the linkage between insulin resistance and meta-inflammation in morbid obese.

Helicobacter pylori Increases Gastric Compliance on Resected Stomach After Laparoscopic Sleeve Gastrectomy.

BACKGROUND: The relationship between high body mass index (BMI) and Helicobacter pylori (HP) was reported previously. But the mechanism is not clear. We aimed to evaluate the effect of HP on gastric compliance and volumes in obese patients. MATERIALS AND METHODS: One hundred fifty-nine patients who underwent sleeve gastrectomy due to morbid obesity were enrolled in the study and were divided into two groups as HP+ (n = 86) and HP- (n = 73) according to the HP status in resection materials. Demographics, pathological data, specimen sizes, volume, and compliance were retrospectively analyzed. RESULTS: The median age of the study group was 34 years (17-64 years) while the median BMI was 43 kg/m2 (35-64, 3 kg/m2). Most of the patients (n = 134, 84.3%) were female. The median diameter of the widest point of the specimen was 22.5 cm (14-32 cm), and the median volume of the specimen was 790 cc (330-1920 cc). Both the diameter of the widest point and the volume of the specimens were significantly increased in the HP+ group compared to the HP- group (p < 0.001 and p = 0.017, respectively). In addition, the median compliance was 52.6 cc/mmHg, and the compliance was significantly higher (p < 0.001) in the HP+ group. There were no significant differences in specimen sizes between the two groups. CONCLUSION: This is the first study showing that HP increases gastric compliance in obese patients who underwent LSG. The etiology and the effects of this increase in compliance have not been fully clarified yet. Further studies are needed to shed light on these effects.

Being on the side of old findings: progesterone elevation on the day of oocyte maturation induction does not affect embryological parameters throughout the blastocyst culture period.

PURPOSE: To investigate whether there is any detrimental effect of progesterone elevation (PE) on the day of oocyte maturation induction on embryological development potentials. METHODS: This retrospective single-center cohort study included a total of 1485 individual intracytoplasmic sperm injection (ICSI) cycles between January 2014 and December 2018. Serum progesterone (P) levels were measured on the day of oocyte maturation induction following the GnRH antagonist suppression protocol. Embryological parameters such as maturation, fertilization rate (FR), top-quality embryo (TQE) formation rate per 2PN on day 3, and excellent-quality blastocyst (EQB) formation rate per 2PN on day 5/6 were recorded. The inclusion criteria for women were an age ≤ 37 years, a BMI ≤ 30 kg/m2, and access to a total sperm concentration ≥ 2 million. Groups were stratified according to the serum P levels using the cut-off levels of < 0.8 ng/ml; 0.8-1.49 ng/ml; and ≥ 1.5 ng/ml. RESULTS: Peak E2 level and total number of oocytes retrieved were significantly related to PE (p < 0.001). FR did not display a significance difference between groups (p = 0.108). The TQE and the blastulation rates were not affected by PE (p = 0.82 and p = 0.68, respectively). Chi square analysis revealed a significant relationship between PE and the EQB formation rate (p = 0.01). GEE analysis failed to present any statistical significance regarding the effect of PE on neither the TQE nor the EQB formation rates per 2PN [OR 1.07; 95% (0.98-1.16) p = 0.113 and OR 0.93; 95% (0.80-1.07) p = 0.32, respectively]. CONCLUSIONS: In accordance with previously published papers, our study could not find any detrimental effect of PE on embryological outcomes throughout the blastocyst culture period.

The critical shoulder angle, the acromial index, the glenoid version angle and the acromial angulation are associated with rotator cuff tears.

PURPOSE: To compare the critical shoulder angle (CSA), acromion index (AI), acromion angulation (AA) and glenoid version angle (GVA) between patients with full-thickness rotator cuff tears (RCTs) and patients with intact rotator cuffs. METHODS: Between 2014 and 2018, the CSA, AI, AA and GVA were measured in consecutively included patients aged > 40 years who underwent shoulder arthroscopy for full-thickness RCTs. A total of 437 patients with RCTs and a mean age of 51.2 years (± 5.8) were included, 35.7% of whom were male. In the control group, there were n = 433 patients (36.3% male) with an intact rotator cuff, and the mean age was 50.7 years (± 5.3). RESULTS: The mean AI for the RCT group was 0.7 ± 0.1, which was significantly higher than the mean AI for the control group (0.6 ± 0.1, p < 0.001). The mean CSA for the RCT group was 33.6° ± 3.9°, which was significantly higher than the mean CSA for the control group (31.5° ± 4°, p < 0.001). The mean AA for the RCT group was 13.9° ± 9°, which was significantly higher than the mean AA for the control group (12.4 ± 8.6, p = 0.012). The mean GVA for the RCT group was - 3.5° ± 4.6° and significantly retroverted compared with the mean GVA for the control group (- 2.2° ± 4.6°, p < 0.001). The cutoff values determined by the ROC curve analyses were as follows: 0.6 for AI, 31.4° for CSA, 9.6° for AA and - 2.6° for GVA. CONCLUSION: The CSA, AI, GVA and AA values measured by MRI were determined to be significantly related to full-thickness rotator cuff ruptures. The AI, CSA, AA and GVA may be considered risk factors for degenerative rotator cuff tears. Assessing the CSA, AI, GVA and AA can be helpful for diagnostic evaluation of patients with full-thickness RCTs. LEVEL OF EVIDENCE: III.

Age-related decrease in supratrochanteric torsion and increase in infratrochanteric torsion in healthy pediatric femurs: an MRI study.

The aim of the study was to evaluate the correlation between femoral anteversion, supratrochanteric torsion (STT), and infratrochanteric torsion (ITT) in healthy developing pediatric femurs using MRI. This study included 282 (164 males and 118 females) patients aged 1-18 years. The axial MRI of patients with benign tumoral lesions of the femur was retrospectively reviewed. The measurements were performed through axial images of contralateral healthy femurs. Femoral anteversion, STT, and ITT were measured twice by two orthopedic surgeons. The Pearson correlation coefficient was used to test for the correlation of age between STT, ITT, and femoral anteversion in children. All femoral anteversion, STT, and ITT measurements showed excellent intraobserver and interobserver reliability (P < 0.001). The mean STT changed from 68.5° to 37.2° ± 4.2, the mean ITT changed from -37.4° to -21.2° ± 4.2, and the mean femoral anteversion changed from 31.1° to 18.8° ± 2.2 in patients aged 1-18 years. Through the linear regression model, STT, ITT, and femoral anteversion had a significant association (P < 0.001) with age. For an increase of one year in age, the corresponding STT decreased 1.32 times (P < 0.001, R2 = 0.510), the corresponding ITT increased 0.39 times (P < 0.001, R2 = 0.079), and the corresponding femoral anteversion decreased 0.94 times (P < 0.001, R2 = 0.507). ITT increases and STT decreases with age. The decrease in STT contributes more to femoral anteversion than does the increase in ITT. STT and ITT contribute to femoral anteversion with different patterns according to age.

Comparison of intramuscular versus subcutaneous aqueous progesterone for luteal phase support in artificially prepared frozen embryo transfer cycles.

OBJECTIVE: Cryopreservation of embryos for future transfer attempts has noticeably increased in the last decade, especially due to the technological developments in in vitro fertlization (IVF) laboratories. In parallel, different progesterone (P) replacement regimens preceding artificially prepared frozen embryo transfer (AC-FET) attempts, especially with respect to the route of application and dosing scheme, have been widely argued so far. We aimed to provide more information about the efficacy profile of novel subcutaneous aqueous progesterone (SP) in AC-FET cycles. MATERIALS AND METHODS: This retrospective, single-centre cohort study included a total of 507 AC-FET cycles performed between June 2018 and April 2020. Three hundred forty-nine (68.8%) patients received 50 mg of intramuscular progesterone as once daily, 158 (31.2%) patients received 25 mg of SP as twice daily. Only, the first and single blastocyst transfers from the same cohort were accepted. The inclusion criteria were as follows: females aged <37 years, body mass index ≥18 kg/m2 and ≤35 kg/m2, sperm concentration ≥5x106/mL. Pre-implantation genetic testing cycles were not included. The primary outcome was the live birth rate (LBR). RESULTS: The number of previous IVF attempts, type of infertility, peak estradiol (E2) levels, the total number of retrieved oocytes, mature oocytes, and the number of 2PN was significantly different between the groups. Positive pregnancy (p=0.474) and clinical pregnancy rates (p=0.979), LBR (p=0.404), and missed abortion rates (p=0.144) were comparable between the groups. The total number of oocytes [adjusted odds ratios (AOR)=1.024, 95% confidence interval (CI): 1.002-1.047; p=0.03)], endometrial thickness (AOR=1.121, 95% CI: 1.003-1.253; p=0.044), and cryopreservation day 5/6 (AOR=0.421, 95% CI: 0.226-0.788; p=0.007) achieved statistical significance following binary logistic regression analysis. However, P administration type did not achieve statistical significance (p=0.731). CONCLUSION: As a novel option, SP has comparable efficacy in pregnancy outcomes and may be accepted as an alternative for luteal phase support in AC-FET cycles.

Parameters impacting the live birth rate per transfer after frozen single euploid blastocyst transfer.

BACKGROUND: To assess the predictive value of patient characteristics, controlled ovarian stimulation and embryological parameters on the live birth outcome of single euploid frozen-warmed blastocyst transfer (FBT). METHODS: This was a retrospective cohort study including 707 single FBTs after preimplantation genetic testing for aneuploidy (PGT-A) that were performed from October 1, 2015, to January 1, 2018. The effects of patient-, cycle- and embryology-related parameters on the live birth outcome after FBT were assessed. RESULTS: In the subgroup analysis based on live birth, patients who achieved a live birth had a significantly lower body mass index (BMI) than patients who did not achieve a live birth (22.7 (21.5-24.6) kg/m2 vs 27 (24-29.2) kg/m2, p<0.001). The percentage of blastocysts with inner cell mass (ICM) A or B was significantly higher among patients achieving a live birth, at 91.6% vs. 82.6% (p<0.001). Day-5 biopsies were also more prevalent among patients achieving a live birth, at 82.9% vs 68.1% (p<0.001). On the other hand, the mitochondrial DNA (mtDNA) levels were significantly lower among cases with a successful live birth, at 18.7 (15.45-23.68) vs 20.55 (16.43-25.22) (p = 0.001). The logistic regression analysis showed that BMI (p<0.001, OR: 0.789, 95% CI [0.734-0.848]), day of trophectoderm (TE) biopsy (p<0.001, OR: 0.336, 95% CI [0.189-0.598]) and number of previous miscarriages (p = 0.004, OR: 0.733, 95% CI [0.594-0.906]) were significantly correlated with live birth. Patients with elevated BMIs, cycles in which embryos were biopsied on day-6 and a higher number of miscarriages were at increased risks of reduced live birth rates. CONCLUSION: A high BMI, an embryo biopsy on day-6 and a high number of miscarriages negatively affect the live birth rate after single euploid FBT.

Measuring the serum progesterone level on the day of transfer can be an additional tool to maximize ongoing pregnancies in single euploid frozen blastocyst transfers.

BACKGROUND: Endometrial preparation with hormone replacement therapy (HRT) is the preferred regimen for clinicians due to the opportunity to schedule the day of embryo transfer and for patients due to the requirement of fewer visits for frozen-warmed embryo transfers (FET). The increasing number of FETs raises the question of the serum P levels required to optimize the pregnancy outcome on the embryo transfer day. METHODS: This prospective cohort study includes patients who underwent single euploid FET. All patients received HRT with oestradiol valerate (EV) and 100 mg of intramuscular (IM) progesterone (P). FET was scheduled 117-120 h after the first IM administration of 100 mg P. The serum P level was analyzed 1 h before the embryo transfer (ET). In all cycles, only embryos that were biopsied on day 5 were utilized for FET. Next generation sequencing (NGS) was used for comprehensive chromosomal analysis. RESULTS: Overall, the ongoing pregnancy rate (OPR) was 58.9% (99/168). Data were then categorized according to the presence (Group I; n = 99) or the absence (Group II; n = 69) of an ongoing pregnancy. No significant differences regarding, female age, body mass index (BMI), number of previous miscarriages, number of previous live birth, sperm concentration, number of oocytes retrieved, number of mature oocytes (MII), rate of fertilized oocytes with two pronuclei (2PN), trophectoderm score, inner cell mass (ICM) score, endometrial thickness (mm), oestrodiol (E2) and P levels prior to IM P administration were found between two groups. The P levels on the day of ET (ng/ml) were significantly higher in Group I (28 (5.6-76.4) vs 16.4 (7.4-60) p = 0.039). The P level on the day of ET was a predictor of a higher OPR (p < 0.001 OR: 1.033 95%CI [1.009-1.056]) after multivariate analysis. The ROC curve showed a significant predictive value of serum P levels on the day of ET for OPR, with an AUC (95%CI) = 0.716 (0.637-0.795). The optimal cut-off value for prediction of the OPR was a P level of 20.6 ng/ml (71.7% sensitivity, 56.5% specificity). CONCLUSIONS: The present study suggests a minimum threshold of the serum P value on the day of ET that needs to be reached in HRT cycles to optimize the clinical outcome. Individualization of the P dosage should be evaluated in further studies.

Left sided Amyand's hernia.

The presence of the appendix in an inguinal hernia sac has been referred to as Amyand's hernia. Vermiform appendix located in an external hernia sac is not an uncommon condition, and the incidence of these cases is approximately 1%. In Amyand's hernias, appendices are frequently found in the hernia sac; but an incarceration particularly on the left side is a very unusual sight. In this report we present 32-year-old male with Amyand's hernia on the left side.

Could serum ß-hCG levels and gestational age be the indicative factors for the prediction of the degree of trophoblastic invasion into tubal wall in unruptured ampullary pregnancies?

OBJECTIVE: To evaluate the predictive value of gestational age and maternal serum ß-hCG concentration for the determination of the depth of trophoblastic invasion into the tubal wall. METHODS: This is a retrospective trial conducted on women with a diagnosis of ampullary pregnancy (71) who were submitted to salpingectomy. Serum ß-hCG measurements were obtained at the initial admission of hospital. Histological investigation was performed by a single well-experienced pathologist who was blind to the clinical and laboratory characteristics of the patients. Ampullary pregnancy was classified histologically according to the depth of trophoblastic infiltration into tubal wall: trophoblast limited to the tubal mucosa (stage I), extended to muscularis layer (stage II) and complete tubal wall infiltration up to serosal layer (stage III). RESULTS: There was a significant difference in maternal serum ß-hCG concentrations regarding the histological stages of trophoblastic invasion. The serum ß-hCG concentrations that the best predicted for stage III trophoblastic invasion was 6,475 mIU/ml, with a sensitivity of 100 %, a specificity of 92 %. CONCLUSION: The depth of trophoblastic tissue infiltration into tubal wall is correlated with serum ß-hCG levels, but not with gestational age. These findings may explain the reason for conservative management failure of EP in women with high ß-hCG concentrations.

Effects of lumbar lordosis and pelvic inlet orientation on the outcome of the transobturator tape sling operation in women.

PURPOSE: To determine the association between changes in lumbar lordosis (LL) and/or pelvic inlet (PI) orientation and the outcome of a transobturator tape (TOT) sling procedure. METHODS: The study population consisted of 70 patients who underwent the TOT sling procedure for stress urinary incontinence, and were evaluated by a stress test at the sixth month after the surgery. The women were defined as continent on the absence of both subjective complaint of leakage and objective leakage as a result of the test. Cases that failed, even though improvement may have been observed, were considered incontinent. With the use of a standardized protocol, lateral lumbosacral spine/pelvic X-rays were taken with the participants standing in their usual upright posture with hands kept at chest level. From these X-rays, the angle of LL and PI were measured. RESULTS: Of the 70 cases, 42 were continent and 28 were incontinent according to the evaluation done during the sixth month after the TOT procedure. There were no significant differences with respect to age, body mass index, gravidity, vaginal parity, pelvic organ prolapse and comorbid diseases between the continent and incontinent groups. The mean angle of PI in the continent group (34°, range 20-50) was significantly lower than in the incontinent group (37°, range 28-60) (p = 0.012). There was no significant difference in the median angle of LL (32°, range 15-50 in continent group, 34.5°, range 21-56 in incontinent group, p = 0.13) between the two groups. CONCLUSIONS: Women with continence after the TOT sling procedure have lower angle of PI than women with incontinence.
