RESUMO
INTRODUCTION: Herlyn-Werner-Wunderlich syndrome (HWWS) is characterized by uterine didelphys, unilateral cervical obstruction, and ipsilateral renal defects. Owing to its rarity, no standard surgical approach exists. PRESENTATION OF CASE: An 11-year-old girl with severe dysmenorrhea had a duplicated uterus, a right cervical hemorrhagic cyst, and right ipsilateral kidney agenesis, indicative of HWWS. As transvaginal surgery was challenging, we turned to laparoscopic surgery for abdominal cavity inspection and surgical assistance. A longitudinal incision was made on the right uterus, followed by inserting a catheter tube fixed to an intrauterine device (IUD) into the right cervical canal from the anterior wall of the right uterine horn. Subsequently, the right external cervical os was inverted to prevent restenosis. Postoperatively, the hemorrhagic cyst at the right cervix disappeared. The patient had no symptom recurrence 24 months after the surgery. DISCUSSION: The preoperative diagnosis for female genital malformations is complicated, and transvaginal manipulation is often difficult in adolescent girls. Laparoscopy is a valuable tool for evaluating female genital malformations, allowing for a thorough diagnosis and safe surgical treatment. In cases of female genital malformation with cervical obstruction, as in this case, reconstruction of the uterine cervix is important to prevent restenosis after surgery. CONCLUSION: In female genital malformations, laparoscopy provides a comprehensive evaluation of the malformation, assisting in a precise diagnosis and safe surgical treatment. Insertion of the catheter tube with IUD into the uterus and reconstruction of the cervix contribute to preventing restenosis.
RESUMO
Cytokine release syndrome (CRS) is a systemic inflammatory condition caused by an excessive immune response and cytokine overproduction. CRS is a life-threatening condition that is often associated with chimeric antigen receptor T-cell therapy. Despite the increased use of immune checkpoint inhibitors (ICIs), ICI-induced CRS remains rare. The present study describes a case of CRS that occurred after the administration of ICIs for recurrent adenocarcinoma of the uterine cervix. A 49-year-old woman received paclitaxel, carboplatin and pembrolizumab for recurrent cervical adenocarcinoma. On day 27 of the third cycle, the patient was admitted with a fever and suspected pyelonephritis. The following day, hypotension, upper respiratory symptoms and myalgia of the extremities were noted, and the left ventricular ejection fraction (LVEF) was decreased to 20%. Multiorgan failure (MOF) occurred, and the patient received ventilator support and continuous hemodiafiltration. Rhabdomyolysis, pancreatitis, erythema multiforme and enteritis were observed. CRS was diagnosed based on elevated ferritin and IL-6 levels. Steroid pulse therapy was administered; however, the MOF did not improve and the anti-IL-6-receptor monoclonal antibody tocilizumab (TOC) was administered. Subsequently, the LVEF improved to 50%, and the patient was removed from the ventilator on day 4 and from the continuous hemodiafiltration unit on day 6 after TOC administration. The patient was discharged on day 21. In conclusion, considering that ICI-induced CRS is a rare but severe complication, fever and other systemic conditions following ICI administration should be monitored.
RESUMO
Robotic-assisted surgery enables precise manipulations with magnified vision, stereoscopic vision, and forceps with multi-joint functions. It requires unique procedures such as position setting, port placement, roll-in, and docking, which lead to prolonged operation and anesthesia time. Five conditions described below were established at our institution to reduce the time to the initiation of console: (1) changing the patients' position from the flat lithotomy position to the spread legs position; (2) attaching a Hasson cone to hold the umbilical cannula stable; (3) changing the cannula's obturator (inner tube) from blunt to bladeless; (4) fixing the team, and (5) conducting regular docking training. These outcomes were examined in this study. The study included 77 patients who underwent robotic-assisted total hysterectomy for benign uterine disease and stage IA uterine cancer at our individual institution between April 2019 and July 2022. We compared the median time from anesthesia to console initiation between the first half group (cases 1-40) and the second half group (cases 41-77). The former required 91.5 (53-131) minutes, whereas the latter required 59 (37-126) minutes. Appropriate equipment selection and team education can reduce the time to console initiation.

Adenocarcinoma, HPV-independent, mesonephric type (hereafter referred to as "mesonephric carcinoma") arising from the cervix is rare, its treatment has not been established, and its sensitivity to chemotherapy has not been fully investigated. Here we report on a 30-year-old female patient who presented at our hospital with a chief complaint of abnormal genital bleeding. We suspected cervical cancer. Based on examination, biopsy, and imaging, she was diagnosed with stage IIA2 adenocarcinoma of the cervix and was scheduled for surgery. Because she had a SARS-COV-2 infection, she was given two courses of paclitaxel-carboplatin (TC) therapy, based on the then-current surgical risk assessment after SARS-COV-2 infection, with a waiting period of at least 8 weeks. The patient was deemed to have a partial response and was treated with paclitaxel and carboplatin, after which she was deemed to have a partial response and underwent total hysterectomy. A diagnosis of stage IIA2 mesonephric carcinoma, ypT1b2N0M0, was made after histopathologic examination of an excised specimen. The patient was treated with 4 additional courses of TC therapy after surgery, and has had no recurrence in 13 months. We report a first case of response to neoadjuvant chemotherapy with TC regimen in a patient with mesonephric carcinoma of the cervix.

Most cases of tubo-ovarian abscess (TOA) are due to transvaginal infection, while other internal diseases may also be associated with TOAs. We experienced a case of ovarian clear cell carcinoma and rectal carcinoma that was discovered to be a result of TOA. A 46-year-old woman was diagnosed with TOA and referred to our hospital. Laparoscopic abscess drainage was performed, and pathological findings confirmed the presence of ovarian clear cell carcinoma inside the abscess. The tumor marker carcinoembryonic antigen (CEA) was elevated, and rectal cancer was diagnosed by a gastrointestinal endoscopy. Abdominal computed tomography (CT) showed a left adnexal abscess with an air image inside, and penetration of the abscess wall and rectal cancer were observed. Histopathologically, there was an accumulation of neutrophils around the rectal tumor cells. We concluded that the rectal cancer had penetrated the existing ovarian tumor and formed TOA. Non-gynecological diseases may be associated with TOA. It is necessary to consider the possibility that other clinical diseases may be associated with the trigger of TOA.

A patient with schizoaffective disorder and receiving long-term treatment with lithium developed prolonged delirium. She had recently been diagnosed with stage IVB endometrial cancer and presented a deteriorating general condition. Toxic levels of lithium were measured in serum. After hemodialysis, lithium levels gradually decreased and the symptoms disappeared completely.
RESUMO
There is currently controversy regarding the criteria for low and intermediate risk of cervical cancer (CC) after surgery. In the present study, the Gynecology Oncology Group (GOG) score was used to detect intermediate risk. Adjuvant radiotherapy was applied in the case of a GOG score >120. The present study aimed to evaluate the validity of the recurrence risk classification using the GOG score for stage IB-IIA node-negative CC. All cases of stage IB-IIA node-negative CC who underwent radical surgery between February 2007 and December 2015 were retrospectively reviewed. The GOG scores were determined from clinical and pathological findings and accordingly, subjects were divided into 4 groups: A, ≤40; B, >40 and ≤70; C, >70 and ≤120; and D, >120. Overall survival (OS) and recurrence-free survival (RFS) curves were generated using the Kaplan-Meier method. The log-rank test produced an estimated P-value by comparing the OS and RFS of group A (low-score group) with those of others. The present study included 61 patients (mean age, 47.82 years; age range, 22-76 years) and the median follow-up was 79 (39-149) months. Of these, 60 patients were observed for at least 60 months. During the follow-up period, the OS and RFS rates of group C were 94.7 and 84.2%, respectively, while those of group D were 100 and 91.7%, respectively; the OS and RFS of groups A and B were 100%. Log-rank tests for all OS and RFS indicated no significant differences compared to group A. It was indicated that a GOG score ≤70 does not require adjuvant therapy; however, a GOG score >70 requires consideration of adjuvant therapy based on the risk factors which constitute the score.
RESUMO
Endometrioid carcinoma is the most common histological type of concurrent synchronous cancers of the uterus and ovary. Here we report a case of synchronous seromucinous carcinoma of the ovary and mucinous carcinoma of the endometrium with a literature review. A 51-year-old multiparous female complained of irregular bleeding and shortness of breath. Computed tomography revealed a large pelvic mass that consisted of cystic and solid components, a tumor of the endometrium, and a large amount of pleural effusion. An endometrial biopsy indicated adenocarcinoma, and adenocarcinoma cells were found in the pleural fluid. The patient with advanced ovarian cancer or endometrial cancer with massive pleural effusion received three courses of neoadjuvant chemotherapy (NAC) with paclitaxel and carboplatin followed by interval debulking surgery (IDS). The NAC was effective, and IDS was performed with no gross residual lesions. The post-operative diagnosis was seromucinous carcinoma of the ovary in FIGO (2014) stage IVA (ypT3cNxM1a) and mucinous carcinoma of the endometrium in FIGO (2008) stage IA (ypT1aNXM0). Three courses of postoperative TC therapy were performed, and maintenance therapy with Bevacizumab is ongoing. The patient is well without evidence of recurrence, sixteen months after surgery.

A combination chemotherapy of paclitaxel plus carboplatin (TC) is the most frequently used regimen for gynecological malignancies. As long as it is effective, a carboplatin-containing combination chemotherapy is used for every relapse. This implies that the number of platinum administrations and the frequency of hypersensitivity reaction (HSR) increase as the prognosis improves. When a patient develops HSR to carboplatin, we have three options: 1) desensitizing and continuing to use carboplatin, 2) switching to other platinum drugs, or 3) changing to a non-platinum drug. Here we report an experience of an HSR to carboplatin in a patient with recurrent uterine carcinosarcoma. The patient was treated by surgery and TC therapy initially, resulting in no residual disease. The patient relapsed 18 months after the completion of the first-line chemotherapy and was treated with TC therapy again as second-line. An HSR to carboplatin occurred at the 10th cycle of TC in total. We replaced the carboplatin with cisplatin. A chemotherapy including cisplatin and adriamycin was repeated without further HSR. We reviewed the literature regarding HSR to carboplatin and in this paper we summarize the management for dealing with it.

AIM: To evaluate the perioperative complications and the anatomical outcomes of our laparoscopic uterosacral ligament (USL) colpopexy, which is a novel laparoscopic technique for the management of uterine prolapse. The objective was to report on outcome after 2 years of a technique using laparoscopic USL colpopexy. METHODS: A total of 152 uterine prolapse patients underwent laparoscopic USL colpopexy from May 2013 to April 2015. We described the surgical technique and performed a retrospective analysis of this laparoscopic technique. Patients underwent standardized assessment and examination using pelvic organ prolapse quantification (POP-Q) score. The dependent values of Ba point (bladder), C point (vaginal cuff) and Bp point (rectum) were recorded preoperatively, and at 1, 3, 6, 12 and 24 months of postoperative examination. Pre/postoperative data were compared using the Kaplan-Meier method. RESULTS: Mean age, operative time and amount of hemorrhage were 68.2 ± 7.5 years, 118.3 ± 36.4 min and 60.5 ± 73.3 mL, respectively. Overall recurrent prolapse, which was defined as POP-Q stage II or higher, was noted in 29 patients (19%). However, only 2 patients presented recurrent rectocele among 51 patients with preoperative POP-Q stage II of uterine prolapse alone (recurrence rate; 3.9%). The pre/postoperative average POP-Q scores were -0.2/-2.7 cm (P < 0.05) at Ba point, -1.9/-5.1 cm (P < 0.05) at C point and -2.4/-2.3 cm (P = 0.06) at Bp point. CONCLUSION: Laparoscopic visualization of uterosacral ligaments may result in safe colpopexy. Our results show this will be a useful procedure for apical support as native tissue repair.

AIM: Vascular or intestinal injuries at the time of the first trocar insertion can cause serious complications during laparoscopic surgeries. In this study, we evaluate the usefulness of ultrasound scans of the umbilical region as well as intraumbilical conditions to help prevent serious complications. METHODS: The subjects included 430 cases who underwent laparoscopic gynecologic surgeries. The umbilical ultrasound scan was performed after tracheal intubation to observe the intestinal movements associated with respiration. Structures of the umbilical region as well as peristalsis and the movement of the intestinal tract were observed. Then, the thickness of the subcutaneous fat (between the umbilical skin surface and the rectus fascia) and the preperitoneal fat (between the rectus fascia and the peritoneum) were measured. The relationship between body mass index (BMI), insertion time of the first trocar and ultrasound measurements were analyzed. RESULTS: The anatomical structures of the umbilical region (the subcutaneous tissue and the preperitoneal fat) were clearly observed in all cases. The BMI score had a significant relationship with subcutaneous fat thickness (r = 0.547), but remarkably not with preperitoneal fat thickness (r = 0.174). There was no significant relationship between BMI and insertion time. However, insertion time of the first trocar had a significant relationship with preperitoneal fat thickness (r = 0.534). CONCLUSIONS: Preoperative ultrasonography of the umbilical region is asimple process, and it is helpful inpreventing serious complications caused by the first trocar insertion. We have found that preperitoneal fat thickness seems to be an important factor in predicting the potential difficulty of the first trocar insertion.

INTRODUCTION AND HYPOTHESIS: Transvaginal ipsilateral uterosacral ligament colpopexy for pelvic organ prolapse (POP), which was reported by Shull et al. (Shull's colpopexy) in 2000, is one of the most frequently performed non-mesh pelvic floor reconstructive surgical procedures. Despite its excellent anatomical outcomes, ureteral injury and difficulty in uterosacral ligament detection (especially in patients with severe POP) are typical issues with this procedure. METHOD: This video demonstrates the procedure in a 58-year-old woman, gravida 2 para 2, with POP-Q stage II uterine prolapse and stage I cystocele. At the beginning of the operation, the bilateral uterosacral ligaments were confirmed and separated from the ureters after entering the retroperitoneal space. The inferior hypogastric nerve and pelvic nerve plexus were also separated from the uterosacral ligament. After total laparoscopic hysterectomy, three ipsilateral delayed absorbable monofilament sutures were placed between the uterosacral ligament and the vaginal cuff. Retroperitonealization was then performed using a continuous suture with closure of the Douglas pouch. CONCLUSION: Laparoscopic Shull's colpopexy for POP is a secure procedure with the advantages of laparoscopy (magnification and sharing the operative field). This may become one of the most useful operations for apical support as native tissue repair.

OBJECTIVE: Laparoscopic sacrocolpopexy (LSC) has been reported to achieve lower recurrence rates, shorter recovery time, and less dyspareunia. However, as a pelvic organ prolapse (POP) surgery, LSC is problematic because it requires specific techniques and it takes a comparatively longer operative time. In this study, we present our surgical techniques of LSC and their effectiveness for shortening operative times and raising safety. METHODS: Thirty-four women with stage 2 or greater POP who underwent LSC in our hospital between September 2014 and October 2015 were enrolled in this study. The notable points of our operative procedures are as follows: (1) fixing the sigmoid colon to the left lateral abdominal wall for a clearer visualization of the sacral promontory, (2) making a retroperitoneal tunnel (not opening the peritoneum) from the sacral promontory to the Douglas pouch, (3) dissection of the vaginal wall after transvaginal hydrodissection, (4) fixation of mesh to the vaginal wall by using absorbable tacks, and (5) limiting usage of posterior mesh for the patients with posterior vaginal wall descent. RESULTS: The median operative time was 140 (range, 90-255) minutes, and blood loss was 50 (range, 10-1600) mL. The operative time decreased as the surgical techniques improved through experience. No major intra- or postoperative complications occurred. The mean follow-up period was 4 (range, 1 -14) months, and only one patient presented a recurrent grade 2 cystocele. CONCLUSION: Our unique procedures will help shorten operative times and reduce complications of LSC.
RESUMO
Whether nutritional control can retard senescence of immune function and decrease mortality from infectious diseases has not yet been established; the difficulty of establishing a model has made this a challenging topic to investigate. Caenorhabditis elegans has been extensively used as an experimental system for biological studies. Particularly for aging studies, the worm has the advantage of a short and reproducible life span. The organism has also been recognized as an alternative to mammalian models of infection with bacterial pathogens in this decade. Hence we have studied whether the worms could be a model host in the fields of immunosenescence and immunonutrition. Feeding nematodes lactic acid bacteria (LAB) resulted in increases in average life span of the nematodes compared to those fed Escherichia coli strain OP50, a standard food bacteria. The 7-day-old nematodes fed LAN from age 3 days were clearly endurable to subsequent salmonella infection compared with nematodes fed OP50 before the salmonella infection. The worm could be a unique model to study effects of food factors on longevity and host defense, so-called immunonutrition. Then we attempted to establish an immunosenescence model using C. elegans. We focused on the effects of worm age on the Legionella infection and the prevention by immunonutrition. No significant differences in survival were seen between 3-day-old worms fed OP50 and 3-day-old worms infected with virulent Legionella strains. However, when the worms were infected from 7.5 days after hatching, the virulent Legionella strains were obviously nematocidal for the worms' immunosenescence. In contrast, nematodes fed with bifidobacteria prior to Legionella infection were resistant to Legionella. C. elegans could act as a unique alternative host for immunosenescence and resultant opportunistic infection, and immunonutrition researches.

This study aimed to develop a convenient model to investigate the senescence of host defenses and the influence of food and nutrition. A small soil nematode, Caenorhabditis elegans, was grown for 3 days from hatching on a lawn of Escherichia coli OP50 as the normal food source, and subsequently some of the nematodes were fed lactic acid bacteria (LAB). The life spans of worms fed LAB were significantly longer than the life spans of those fed OP50. To investigate the effect of age on host defenses, 3- to 7-day-old worms fed OP50 were transferred onto a lawn of Salmonella enterica serovar Enteritidis for infection. The nematodes died over the course of several days, and the accumulation of salmonella in the intestinal lumen suggested that the worms were infected. The 7-day-old worms showed a higher death rate during the 5 days after infection than nematodes infected at the age of 3 days; no clear difference was observed when the worms were exposed to OP50. We then investigated whether the LAB could exert probiotic effects on the worms' host defenses and improve life span. Seven-day-old nematodes fed LAB from the age of 3 days were more resistant to salmonella than worms fed OP50 until they were infected with salmonella. This study clearly showed that LAB can enhance the host defense of C. elegans and prolong life span. The nematode appears to be an appropriate model for screening useful probiotic strains or dietetic antiaging substances.
