RESUMO
AIM: To identify factors influencing the Trendelenburg angle required during laparoscopic gynecological surgery. METHODS: Patients who underwent laparoscopic surgery at a single university hospital between May 1, 2019, and March 31, 2021 were enrolled. Data were extracted from the medical records, while magnetic resonance imaging scans and all laparoscopic surgery videos were retrospectively reviewed to assess the presence of the small intestine in the pelvic cavity as well as the adhesions at each site. Groups with and without the small intestine in the pelvic cavity, and those requiring a Trendelenburg angle above or below 13° were compared. RESULTS: In total, 219 patients were examined. The Trendelenburg angle was significantly higher (p = 0.004), while a significant increase in ovarian adhesions was observed (p = 0.033; odds ratio [OR], 2.30; 95% confidence interval [CI], 1.05-5.01) in the group without the presence of the small intestine in the pelvic cavity. Furthermore, the group requiring a Trendelenburg angle of ≥13° had significantly thicker subcutaneous fat (p = 0.044) and more ileal adhesions (p = 0.040, OR, 1.82; 95% CI, 1.03-3.23) than the group with an angle of <13°. CONCLUSION: Cases of ileal adhesions or thick subcutaneous fat are more likely to require a Trendelenburg angle of ≥13°. Therefore, Trendelenburg complications should be considered in this group. In addition, ovarian adhesions make it more difficult to exclude the small intestine from the small pelvic cavity, and may be associated with endometriosis.

OBJECTIVES: Human epididymis protein 4 (HE4), a protein secreted by ovarian tumors, has been used as an ovarian tumor marker. This study aimed to improve the usefulness of HE4 to detect malignant ovarian tumors by reviewing the cut-off values. DESIGN: A retrospective study without intervention was conducted. PARTICIPANTS: One hundred forty-nine healthy women (premenopausal, 126; postmenopausal, 23) and 24 patients with ovarian tumors (malignant, 12; benign, 12) participated in the study. SETTING: The study used the Department of Obstetrics and Gynecology of a university hospital in Japan and the university hospital as a workplace from 2016 to 2018. METHODS: The basic performance of the HE4 assay was evaluated, and the serum HE4 levels of participants were measured. Receiver operating characteristic analysis was performed using the HE4 data of the patients. RESULTS: There were no significant differences in HE4 levels between the pre- and postmenopausal groups of healthy women. When the global cut-off values (premenopausal, 70 pmol/L; postmenopausal, 140 pmol/L) were adopted, the clinical sensitivity, specificity, positive predictive value, and negative predictive value were 41.7%, 91.7%, 83.3%, and 61.1%, respectively. Based on the results of the receiver operating characteristic analysis, we set the HE4 cut-off level at 60 pmol/L, regardless of the menopausal status. With the newly set cut-off value, the clinical sensitivity, specificity, positive predictive value, and negative predictive value were 66.7%, 91.7%, 88.9%, and 73.3%, respectively. That is, the clinical sensitivity of HE4 was improved without lowering specificity. LIMITATIONS: The small number of subjects and the fact that the health status of the healthy women was evaluated based on questionnaires were limitations to the study. CONCLUSION: A clinically useful cut-off value for HE4 as an ovarian tumor marker was established regardless of the menopausal status of the women, with improved clinical sensitivity, positive predictive value, and negative predictive value without lowering specificity. Currently, different cut-off values for HE4 in pre- and postmenopausal women are used globally. The cut-off value for CA125 was the same between pre- and postmenopausal women. Therefore, with the newly established cut-off value, HE4 can be used more conveniently in a non-specialized setting, especially when it is used in combination with CA125.

OBJECTIVE: To analyze congenital lateral maxillary growth for patients with bilateral cleft lip and palate (BCLP). DESIGN: A retrospective study. SETTING: Kanagawa Children's Medical Center. MATERIALS: Images from computed tomography (CT) of patients with BCLP and control patients that were previously used for treatment. MAIN OUTCOME MEASURES: The following landmarks were used: A, the posterior most point of the piriform aperture; B, the superior most point of the acoustic meatus; C, the point at which line A-B intersects the line drawn perpendicular from line A-B to the maxillary tuberosity; and D, the apical most point of the nasal bone. The following distances were then measured using these landmarks: (1) A-B distance; (2) A-C distance; (3) A-C/A-B; (4) the angle between lines A-B and A-D (â BAD); and (5) B-D distance. RESULT: Mean A-B and A-C distances and A-C/A-B were significantly smaller in the BCLP group than in the control group (P < .01 each). Mean â BAD was significantly larger in the BCLP group than in the control group (P < .01). Mean B-D distance did not differ significantly between groups. CONCLUSIONS: Our results indicated that the lateral maxillary segments of patients with BCLP were more posterior than those of the control group, and segment length was shorter compared to the control group on 3D-CT analysis. The lateral maxillary segments of patients with BCLP were basically suggested to originally be underdeveloped.

Radiotherapy is an essential component of cancer therapy. Carbon ion radiotherapy (CIRT) promises to improve outcomes compared with standard of care in many cancers. Nevertheless, clinicians often observe in-field recurrence after CIRT. This indicates the presence of a subset of cancers that harbor intrinsic resistance to CIRT. Thus, the development of methods to identify and sensitize CIRT-resistant cancers is needed. To address this issue, we analyzed a unique donor-matched pair of clinical specimens: a treatment-naïve tumor, and the tumor that recurred locally after CIRT in the same patient. Exon sequencing of 409 cancer-related genes identified enrichment of somatic mutations in FGFR3 and FGFR4 in the recurrent tumor compared with the treatment-naïve tumor, indicating a pivotal role for FGFR signaling in cancer cell survival through CIRT. Inhibition of FGFR using the clinically available pan-FGFR inhibitor LY2874455 sensitized multiple cancer cell lines to carbon ions at 3 Gy (RBE: relative biological effectiveness), the daily dose prescribed to the patient. The sensitizer enhancement ratio was 1.66 ± 0.17, 1.27 ± 0.09, and 1.20 ± 0.18 in A549, H1299, and H1703 cells, respectively. Our data indicate the potential usefulness of the analytical pipeline employed in this pilot study to identify targetable mutations associated with resistance to CIRT, and of LY21874455 as a sensitizer for CIRT-resistant cancers. The results warrant validation in larger cohorts.

OBJECTIVE: The ubiquitin C-terminal hydrolase L1 (UCHL1) plays a key role in tumor invasion and metastasis. Ubiquitin C-terminal hydrolase L1 is overexpressed in various cancers and reported to be correlated with a poor prognosis. The objective of this study was to determine the prognostic significance of UCHL1 in endometrial cancer. METHODS: The expression of UCHL1 in endometrial cancer was assessed using quantitative reverse transcription polymerase chain reaction and immunohistochemistry in 56 and 215 resected tumor specimens, respectively. RESULTS: The 4-year survival rates of the high UCHL1 messenger RNA expression group and high UCHL1 protein expression group were 78% and 71%, respectively, compared with 96% and 95% for the low UCHL1 messenger RNA expression group and low UCHL1 protein expression group, respectively. Kaplan-Meier and log-rank tests indicated a significant correlation between expression of UCHL1 and disease-free survival and overall survival. Moreover, multivariate stepwise Cox proportional hazard regression model analysis showed that UCHL1 was a significant independent marker for predicting a poor disease-free survival and overall survival. In 43 patients with metastatic lesions, immunohistochemical analysis of metastatic lesions revealed that the recurrence rate and mortality rate were 62% and 41%, respectively, in 29 UCHL1-positive patients and 36% and 29%, respectively, in 14 UCHL1-negative patients. CONCLUSIONS: The results of this study suggest that high UCHL1 expression is a strong marker of poor prognosis of endometrial cancer. Furthermore, we suggest that UCHL1 may be involved in the development of distant metastasis in endometrial cancer.

BACKGROUND: Endometrial cytology by direct intrauterine sampling is the most common test for an initial evaluation of the endometrium in Japan. However, its diagnostic value for endometrial cancer remains unknown. Here, we assess the correlation between cytopathology and histopathology to evaluate the diagnostic value of cytology for endometrial cancer. METHODS: Patients with histologically confirmed endometrial cancer and controls with a normal endometrium confirmed by hysterectomy had all undergone preoperative endometrial cytology between 2001 and 2010 at our eight institutions and were retrospectively analyzed. The cytological results were compared by clinical stage, histological type, differentiation, and sampling instrument. RESULTS: We analyzed 1,441 endometrial cancer and 1,361 control cases. Endometrial cytology detected cancer in 1,279 (916 positive and 363 suspicious) cases with a sensitivity (positive plus suspicious cases) of 88.8% and a specificity of 98.5%. The positive rate was high in advanced-stage, nonendometrioid, and undifferentiated cases, but there was no significant difference in sensitivity between these clinical conditions. CONCLUSION: Endometrial cytology shows a relatively high sensitivity and specificity for endometrial cancer, and neither statistical measure is significantly affected by clinical stage, histological type, differentiation, sample numbers, or sampling instrument. These findings form a superior dataset for evaluating the efficacy of endometrial cytology.

The mucosal graft and flaps method (MG method) is a palatoplasty technique that was developed for the purpose of improving maxillary growth in patients with cleft palate. In the MG method, full-thickness buccal mucosa is grafted onto the raw surface created by pushback palatoplasty. The method is unlikely to result in severe scarring and has a favorable effect on maxillary growth. In addition, it is unlikely to result in oronasal fistula and provides good speech results. Overall, postive long-term treatment results have been obtained. Although the MG method is technically difficult and requires a lengthy surgery, the technique is considered to be effective for palate closure in terms of speech and maxillary growth.

In patients with bilateral cleft lip and palate (BCLP) with protrusion and/or torsion of the premaxilla, achieving a favorable outcome with adequate facial and maxillary development remains challenging. In the present study, we report a retrospective cohort of patients with complete BCLP who were treated between 2017 and 2020 at a single center in Japan. We investigated the effects and complications of primary vomerine osteotomy (PVO) with gingivoperiosteoplasty (GPP) following pre-surgical orthodontics (PSO) for premaxillary protrusion and/or torsion. For patients with residual premaxillary protrusion and/or torsion after PSO, PVO, and GPP were performed. The distances and angles of the premaxilla were measured on dental casts before PSO, on the day of PVO, after PVO, and on the day of palatoplasty after cheiloplasty. We further assessed postoperative complications. From a total of 36 patients with complete BCLP after PSO, seven patients underwent PVO with GPP. Proper positioning of the premaxilla was achieved in all seven patients. The distance between the anterior edge of the premaxilla and the anterior edge of the lateral segment and the length of the premaxillary-lateral segment on both sides continued to decrease over time. Loosening of GPP sutures occurred in two cases, although no major complications such as necrosis of the premaxilla or fistula formation occurred. Vomerine osteotomy with GPP before primary cheiloplasty is a potential treatment option in BCLP when the premaxilla still protrudes despite PSO or because PSO cannot be applied.

OBJECTIVE: In Japan, perioperative prophylaxis of pulmonary embolism (PE) in gynecologic cancer patients with preoperative asymptomatic venous thromboembolism (VTE) has not been well established yet. The GOTIC-VTE trial was a prospective, multi-center, single-arm clinical trial to investigate the prevention of postoperative symptomatic PE onset by seamless anticoagulant therapy from the preoperative period to 4 weeks after surgery instead of using intermittent pneumatic compression. METHODS: Anticoagulant therapy was started immediately after asymptomatic VTE diagnosis and stopped preoperatively according to the rules of each institution. Unfractionated heparin administration was resumed within 12 hours postoperatively, and this was followed by the switch to low-molecular-weight heparin and subsequently, edoxaban; this cycle was continued for 28 days. Primary outcome was the occurrence of symptomatic PE in 28 days postoperatively. Secondary outcomes were the incidence of VTE-related events in 28 days and 6 months postoperatively and protocol-related adverse events. RESULTS: Between February 2018 and September 2020, 99 patients were enrolled; of these, 82 patients were assessed as the full analysis set, including 58 for ovarian cancer, fallopian tube, or peritoneal cancer; 21 for endometrial cancer; and 3 for cervical cancer. No symptomatic PE was observed within 28 days postoperatively; two patients had bleeding events (major bleeding and clinically relevant nonmajor bleeding) and three had grade 3 adverse events (increased alanine transaminase, aspartate aminotransferase, or gamma-glutamyl transferase). CONCLUSION: The multifaceted perioperative management for gynecologic malignancies with asymptomatic VTE effectively prevented postoperative symptomatic PE. TRIAL REGISTRATION: JRCT Identifier: jRCTs031180124.

INTRODUCTION: Maxillary development is often inadequate in bilateral cleft patients. The use of presurgical orthopedics (PSO) and gingivoperiosteoplasty (GPP) may promote bone formation at the alveolar cleft, but can also have detrimental effects on maxillary development. Our objective was to investigate the effect of PSO and GPP on maxillary development in bilateral cleft lip and alveolus (BCLA) patients. SUBJECTS AND METHODS: We had 3 complete BCLA patients who had received PSO. All patients underwent cheiloplasty and GPP simultaneously. At 4 years, maxillary protraction head gear was used as part of the protocol. They were evaluated by cephalometric analysis at 4 and 8 years of age, and by CT imaging at 5 years of age. RESULTS: At 4 years of age, patients with all BCLA had anterior crossbite of deciduous central incisors. As a result of maxillary protraction, jaw development at 8 years was good. Among all patients, only one showed bone formation at the alveolar cleft sufficient to avoid alveolar bone grafting (ABG). DISCUSSION: All patients presented anterior crossbite in the premaxillary region, but had good maxillary growth at 8 years old as a result of maxillary protraction. The combination of PSO and GPP can potentially eliminate the need for ABG and does not significantly retard maxillary development. PSO with GPP and protraction head gear may be an option, but long-term growth is not known.

Characteristic features of popliteal pterygium syndrome (PPS) associated with the craniofacial region include cleft palate, syngnathia, and difficulty with reconstruction. We developed a new procedure of submucosal dissection with periosteotomy to close the folded mucosa in bilateral cleft lip and palate patients with PPS. This technique could be applicable for patients with wide cleft palate.
RESUMO
BACKGROUND: Distraction osteogenesis is now an important clinical tool in craniofacial surgery. However, controlling the distance and vector of distraction in infants with syndromic craniosynostosis with good repeatability is a task that still proves difficult today. We have developed a new facial osteogenesis distraction system that combines the advantages of external and internal distraction devices to enable control of both the distraction distance and vector. This article describes the method and short-term results of this system. METHODS: Our distraction system uses both a conventional external distraction device and a newly developed internal distraction device. Postoperative control of the distraction vector is performed using the external device, whereas control of distraction distance is done with the adjustable-angle internal device. This system was used for 2 patients with Crouzon syndrome. RESULTS: The system enabled control of lengthening distance and vector, and no complications occurred during the procedures. CONCLUSIONS: We developed a facial distraction system leveraging the advantages of external and internal distraction devices, which we then used to successfully control both lengthening distance and vector. The system would be particularly indicated in patients with severe scarring due to multiple follow-up surgeries and in patients requiring distraction of 20 mm or more. Aligning the periorbital profile at 5 to 6 years old caused the maxilla to rotate counterclockwise, and we consider that a procedure combining Le Fort III osteotomy with Le Fort I and II osteotomies is required to prevent these rotations.

Furlow double-opposing Z-plasty (FDOZ) as primary palatoplasty for the bilateral cleft lip and palate (BCLP) closure often leads to a palatal fistula formation in cases with wide clefts. We examined the utility of the calculated maximum closable cleft width to determine the feasibility of a direct palatal closure without lateral incisions. In this retrospective study, we analyzed consecutive patients with a BCLP who were treated for 5 years from 2009. In sixty-three BCLP patients, the following dimensions were measured preoperatively: an actual distance between maxillary tuberosities (Actual X); actual cleft height, calculated from the line joining the maxillary tuberosities to the cleft edge (Actual Y); and actual cleft width at the hard-soft palate junction (Actual Z) and calculated maximum cleft width requiring a direct closure (CMZ). Six months postoperatively, the relationships between the fistula occurrence and actual Z/CMZ were examined. Median values (interquartile range) of Actual X, Y, and Z and CMZ were 35.0 (33.0-39.0) mm, 7.0 (6.0-8.0) mm, 10.0 (8.0-11.0) mm, and 4.6 (2.7-5.7) mm, respectively. The median age at operation was 8.0 (7.0-17.0) months. Fistulae at the hard-soft palate junction developed postoperatively in three cases with more than a 10-mm cleft width (4.76%). A receiver operating characteristic (ROC) curve analysis indicated that actual Z was a better predictor of a postoperative fistula formation than CMZ. An actual cleft width was a better predictor of the fistula occurrence than a calculated maximum cleft width after FDOZ for a BCLP repair. The low fistula rate of FDOZ suggested that FDOZ could be used to close the palate with less than a 10-mm cleft width.

We herein report a retrospective analysis of the efficacy of a combination therapy of pelvic irradiation that excluded the common iliac lymph nodes region and image-guided brachytherapy (IGBT) for non-bulky (≤4 cm) cervical cancer. Thirty-three patients with stage I-II cervical squamous cell carcinoma (≤4 cm) and without pelvic/para-aortic lymphadenopathy who were treated with definitive radiotherapy alone between February 2009 and September 2016 were included. The radiotherapy consisted of CT-based small-pelvis irradiation (whole pelvis minus common iliac lymph node area) of 20 Gy/10 fractions followed by pelvic irradiation with a midline block of 30 Gy/15 fractions and IGBT of 24 Gy/4 fractions (6 Gy/fraction for high-risk [HR] clinical target volume [CTV] D90%). In-room computed tomography (CT) imaging with applicator insertion was used for brachytherapy planning, with physical examinations and diagnostic magnetic resonance imaging (MRI) also being referred to for determination of HR CTV. Over a median follow-up of 60.5 months (range, 7-89), two patients developed distant recurrence and one developed local and distant recurrence. Two patients died from cervical cancer, one from hepatocellular carcinoma and one from non-cancerous disease. The 2/5-year local control (LC), progression-free survival (PFS) and overall survival (OS) rates were 100%/96.7%, 93.8%/90.6% and 93.9%/93.9%, respectively. No pelvic/para-aortic lymph node recurrence was observed. There were no late complications of grade 3 or higher in the small bowel, large bowel/rectum, or bladder. Our results suggest that a combination therapy of IGBT plus small-pelvis irradiation excluding common iliac lymph nodes provides reasonable clinical outcomes and can be a treatment option in non-bulky (≤4 cm) cervical squamous cell carcinoma.

The aim of this study was to retrospectively estimate intervention outcomes and to establish suitable indications for autogenous tiered cartilage augmentation (ATCA) of the posterior pharyngeal wall for velopharyngeal insufficiency (VPI). The sample cohort comprised 17 consecutive patients with VPI (10 boys, 7 girls), excluding syndromic cases. Pre- and postoperative findings were comprehensively evaluated using a combination of speech assessment and lateral pharyngography (LPG). Hypernasality and consonant distortion were scored (normal: 0; mild: 1; moderate: 2; severe: 3). Velopharyngeal gap size at rest (AC) and at maximum closure (BC) were measured on LPG. All patients displayed improvements in velopharyngeal function and speech score, and no patients required re-operation. Pre- and postoperative hypernasality scores were 1.9 ± 0.5 and 0.6 ± 0.5, respectively (Pâ<â.001). Pre- and postoperative consonant distortion scores were 1.9 ± 0.6 and 0.6 ± 0.5, respectively (Pâ<â.001). Pre- and postoperative AC distances were 8.2 ± 3.4 mm and 5.9 ± 2.6 mm, respectively (Pâ<â.001). Pre- and postoperative BC distances were 3.9 ± 2.4 mm and 0.3 ± 0.8 mm, respectively (Pâ<â.001). Conclusions: ATCA appears effective for surgical treatment of VPI patients with a gap less than 10 mm.

The objective of this study was to propose prognostic factors and optimal treatment strategies by analyzing the clinicopathological features and programmed death-ligand 1 (PD-L1) expression. We analyzed 31 patients diagnosed with uterine or ovarian melanoma between 1997 and 2017 in the Kansai Clinical Oncology Group/Intergroup. Twenty-four and seven patients with cervical and ovarian melanomas were included, respectively. Immune checkpoint inhibitors were used in seven patients, and the objective response rate was 40%. Notably, two patients with objective responses had a high PD-L1 expression. Ten and four patients with cervical and ovarian melanomas, respectively, had high PD-L1 immunohistochemical expressions. Multivariate analysis revealed that tumor stage was an independent prognostic factor for progression-free survival in patients with cervical melanomas. In patients with ovarian melanomas, the 1-year cumulative progression-free and overall survival rates were 0 and 29%, respectively. Kaplan-Meier analyses revealed that age <60 years was associated with poorer progression-free and overall survivals in patients with ovarian melanomas. In patients with cervical melanomas, the 1-, 3-, and 5-year cumulative overall survival rates were 53, 32, and 16%, respectively. Histological atypia was associated with a poorer progression-free survival, but there was no difference in survival between patients who underwent radical hysterectomy and those who did not. The present study is a large cohort study of uterine and ovarian melanomas, which are aggressive tumors with a significantly poor prognosis, even after standard surgery and adjuvant therapy. The use of immune checkpoint inhibitors is a promising and effective treatment option.

Cleft palate patients with a short palate are sometimes encountered and it is difficult to achieve effective primary palatoplasty and good speech in these cases. Our purpose was to establish an effective palatoplasty for a cleft palate patient with Randall type III short palate. Buccal musculomucosal flap on the nasal side and skin graft on the oral side were performed, along with double opposing Z-plasty. Speech improved postoperation. This procedure brought the nasopharyngeal area closer to the normal anatomical state. In terms of disadvantages, the procedure is rather complicated and depends on the engraftment rate.
RESUMO
A case of congenital short palate was treated by bilateral buccal musculomucosal flaps. The levator veli palatini muscle formed a continuous sling, but the anterior portion was attached to the posterior border of the hard palate. The speech outcome improved from severe to normal.
RESUMO
It takes quite a long time to finish treating patients with cleft lip and palate. Usually, lip closure, palate repair, secondary alveolar bone grafting, and secondary repair of lip/nose have been given to patients at appropriate time according to their growth. However, these series of surgical interventions impose a considerable burden on the patients and their families. As for palate repair, it is considered that the earlier the better for the sake of speech, but it should be delayed to approximately 1(1/2) years of age for maxillary growth. However, we have developed a palate repair technique that will hardly result in marked maxillary growth impairment by modifying the Furlow method, so we have become able to perform palate repair between 3 and 10 months after birth. Accordingly, we can perform lip and palate repair simultaneously, which have been performed separately. As we have developed a 1-stage repair of cleft lip and palate including primary alveolar bone grafting from nasal concha and/or hard plate and gingivoperiosteoplasty or gingivomucoperiosteal flap, we report on our technique and treatment outcome.

Patients with bilateral cleft lip and palate (BCLP) generally require several stages of treatment, and adequate maxillary development without orthognathic surgery is not easy to achieve. The purpose of this study was to determine short-term outcomes of orthodontic premaxillary setback (OPS) and premaxillary osteotomy (PO) for complete BCLP treatment. PATIENTS AND METHODS: Twenty-six patients with BCLP were consecutively treated for 4 years by a single surgeon. All patients were categorized by three indications for the first operation: OPS1, cheiloplastyâ¯+â¯gingivoperiosteoplasty (GPP)â¯+â¯palatoplasty; OPS2, cheiloplastyâ¯+â¯GPP; and PO, cheiloplastyâ¯+â¯GPPâ¯+â¯PO. Cephalograms for maxillary growth and velopharyngeal function (VPF) were judged at 4 years old, before orthodontic treatment. RESULTS: OPS1 was performed in 14 cases, OPS2 in 8 cases, and PO in 4 cases. As for cephalometric analysis at 4 years old, no significant differences between groups were seen in any cephalometric measurements. As for speech outcomes, assessment of VPF at 80.8±14.8 months was good in 17 cases, slightly impaired in 8 cases, and marginally impaired in 1 case, with no severely impaired cases. DISCUSSION: No significant differences in maxillary growth or speech outcomes were seen between OPS1, OPS2, and PO groups at 4 years old, possibly because all groups showed the same position of the premaxilla after the first operation. CONCLUSIONS: No significant differences in maxillary growth or speech outcomes were seen for 26 patients with BCLP between OPS1, OPS2, and PO groups at 4 years old. However, the long-term growth characteristics remain unclear.
