Endometrioid ovarian adenocarcinoma is a common subtype of epithelial ovarian cancer that can arise on a background of endometriosis. Maximal cytoreductive effort with an aim to remove all macroscopic disease (achieve R0) is the single independent prognostic factor for survival. Complex multidisciplinary surgeries may be required in order to achieve this.

OBJECTIVE: This video illustrates a rare surgical case involving a urethral diverticulum, urethrovaginal fistula, and mesh erosion.
METHODS: We present a 58-year-old patient attending a tertiary care center with a suspected urethrovaginal fistula. Her concerns included stress urinary incontinence (SUI), recurrent urinary tract infection, and vaginal pain. The surgical history was notable for the placement of two different mesh slings during the same procedure to treat SUI. Preoperative evaluation and findings are illustrated in detail. The video uses a high-definition surgical camera to emphasize the initial intraoperative evaluation with localization of the fistula and diverticulum. We then demonstrate the approach to the dissection with the goal of ensuring complete resection of the diverticulum, fistula, and mesh, while preserving healthy tissue for subsequent closure. The utilization of unique and specialized tools for each portion of the procedure is also illustrated. A layered vaginal closure, including a Martius flap, is created to prevent recurrence.
RESULTS: The surgery was accomplished without complications.
CONCLUSIONS: To our knowledge, concomitant findings of a urethral diverticulum, urethrovaginal fistula, and mesh erosion are unique in the literature. We postulate that this triad could have resulted from the mesh burden in this particular patient.

UNASSIGNED: Secondary hematocolpos is a rare but serious complication after cystocele repair. This warrants multidisciplinary management (gynecology and urology) to optimize outcomes & minimize iatrogenic risks.
UNASSIGNED: Hematocolpos is the term used for the accumulation of menstrual blood in the vagina. It is most commonly seen in adolescent girls but can also occur in elderly women as a result of gynecological conditions. We present the case of a 48-year-old female who presented with amenorrhea and abdominal pain following surgical repair of a cystocele. Investigation revealed secondary hematocolpos due to surgical trauma. Surgical drainage and correction of the uterus were performed, resulting in immediate pain relief. This case underscores the importance of considering hematocolpos in patients with post-surgical amenorrhea, and further research is needed to better understand its causes, risk factors, and optimal management strategies.

(1) Introduction: The laparoscopic approach to low pelvic tumors is challenging and hindered by suboptimal tumor visualization and dissection, with possible oncological failure. Stereotactic navigation provides real-time image guidance that may optimize safety, accuracy, and precision when dissecting challenging low pelvic tumors. (2) Methods: Preoperative CT images were acquired with eight skin-fixed fiducials and loaded into a navigation system. A patient tracker was mounted on the bed side. Patient-to-image paired point registration was performed, and an instrument tracker was mounted on a laparoscopic instrument and calibrated for instrument tracking. Surgical operations were performed with real-time stereotactic navigation assistance. (3) Results: Three patients underwent stereotactic navigation surgery. Fiducial registration errors were good to optimal (±1.9, ±3.4, and ±3.4 mm). Lesions were easily identified and targeted with real-time navigation. Surgeries were uneventful. Histopathology examinations identified one retro-rectal schwannoma, one lateral pelvic recurrence from rectal adenocarcinoma, and one advanced anal canal carcinoma. No navigation-related complications, readmissions, or postoperative mortalities were observed. (4) Conclusions: The application of laparoscopic stereotactic navigation surgery to complex low pelvic tumors is feasible and could impact oncological surgical quality by enabling tumor targeting and ensuring resection margins. Further wider series are needed to confirm stereotactic navigation\'s impact on challenging low pelvic tumors.

We present the case of a patient who developed a massive right pleural effusion after pelvic surgery, not thoracic surgery. Lymphatic leakage into the abdominal cavity after pelvic surgery can cause massive pleural effusion when complicated with porous diaphragm syndrome.

In the past, quadratus lumborum block (QLB) was mostly used for postoperative analgesia in patients, and few anesthesiologists applied it during surgery with opioid-free anesthesia (OFA). Consequently, it is still unclear whether QLB in the supine position can provide perfect analgesia and inhibit anesthetic stress during surgery under the OFA strategy. To observe the clinical efficacy of ultrasound-guided quadratus lumborum block (US-QLB) in the supine position with OFA for lower abdominal and pelvic surgery. A total of 122 patients who underwent lower abdominal or pelvic surgery in People\'s Hospital of Wanning between March 2021 and July 2022 were selected and divided into a quadratus lumborum block group (Q) (n = 62) and control group (C) (n = 60) according to the random number table method. Both groups underwent general anesthesia combined with QLB in the supine position. After sedation, unilateral or bilateral QLB was performed via the ultrasound guided anterior approach based on images resembling a \"human eye\" and \"baby in a cradle\" under local anesthesia according to the needs of the operative field. In group Q, 20 ml of 0.50% lidocaine and 0.20% ropivacaine diluted in normal saline (NS) were injected into each side. In group C, 20 ml of NS was injected into each side. The values of BP, HR, SPO2, SE, RE, SPI, NRS, Steward score, dosage of propofol, dexmedetomidine, and rocuronium, the number of patients who needed remifentanil, propofol, or diltiazem, puncture point, block plane, duration of anesthesia, catheter extraction, and wakefulness during the operation were monitored. There were no significant differences in the general data, number of cases requiring additional remifentanil, propofol, or diltiazem treatment, as well as puncture point and puncture plane between the two groups (P > 0.05). HR, SBP, and DBP values were higher in group Q than in group C at T1; HR, SPI, and SE, while RE values were lower in group Q than in group C at T3, SE, and RE; the Steward score was higher in group Q than in group C at T4 and T5, and the difference was statistically significant (P < 0.05). The extubation and awake times were lower in group Q than in group C, and the difference was statistically significant (P < 0.05). The SE, RE, and SPI values were lower at T1, T2, T3, and T4 than at T0. The Steward scores at T4 and T5 were higher in group Q than in group C, and were lower than at T0, with a statistically significant difference (P < 0.05). There were significant differences in the effectiveness of postoperative analgesia between the two groups at t1, t3 and t4 (P < 0.05). US-QLB in the supine position with OFA is effective in patients undergoing lower abdominal or pelvic surgery with stable intraoperative vital signs, complete recovery and better postoperative analgesia.

The obturator artery (OA) is typically a branch of the anterior division of the internal iliac artery. However, an aberrant obturator artery origin may lead to clinical complications. Because of its location in the pelvic cavity, the OA is at high risk of injury or laceration during a variety of pelvic surgeries. Regarding this, variations in the origins of the OA may result in bleeding that can often be overlooked, rendering treatment ineffective. Our study aimed to assess the origins and course of the OA in Midwestern American donor bodies. Sixty-two donor bodies were obtained from the Gift of Body Donation Program at A.T. Still University\'s Kirksville College of Osteopathic Medicine. The origin of each OA was documented and photographed. The OA was identified by observing the vessel\'s passage through the obturator foramen. Of 132 OAs studied, 72 (54.5%) had an aberrant OA. Further, 22 (16.7%) had an aberrant OA origin from the inferior epigastric artery, 20 (15.2%) had an aberrant OA origin from the posterior division of the internal iliac artery, 22 (16.7%) had an aberrant OA origin from dual origins of the anterior division of the internal iliac artery and the inferior epigastric artery, and eight (6.1%) had other aberrant OA origins. Overall, our results indicated anatomical variations are common in the origins and course of the OA. These data highlight the importance of considering variations in the OA and the prevalence of those variations during vascular and orthopedic procedures.

BACKGROUND: Versius CMR is a novel robotic system characterized by an open surgical console and independent bedside units. The system has potentials of flexibility and versatility, and has been used in urological, gynecological, and general surgical procedure. The aim is to depict a comprehensive analysis of the Versius system for pelvic surgery.
METHODS: This is a study involving two Institutions, ASST Santi Paolo and Carlo, Milan, and Apuane Hospital, Massa, Italy. All interventions performed in the pelvic area with the Versius were included. Data about indications, intra-, and post-operative course were prospectively collected and analyzed.
RESULTS: A total of 171 interventions were performed with the Versius. Forty-two of them involved pelvic procedures. Twenty-two had an oncological indication (localized prostate cancer), the remaining had a non-oncological or functional purpose. The mostly performed pelvic procedure was radical prostatectomy (22) followed by annexectomy (9). No intra-operative complication nor conversion to other approaches occurred. A Clavien II complication and one Clavien IIIb were reported. Malfunctioning/alarms requiring a power cycle of the system occurred in 2 different cases. An adjustment in trocar placement according to patients\' height was required in 2 patients undergoing prostatectomy, in which the trocar was moved caudally. In two cases, a pelvic prolapse was repaired concomitant with other gynecological procedures.
CONCLUSIONS: Pelvic surgery with the Versius is feasible without major complications; either dissection and reconstructive steps could be accomplished, provided a proper OR setup and trocar placement are pursued. Versius can be easily adopted by surgeons of different disciplines and backgrounds; a further multi-specialty implementation is presumed and long-term oncological and functional outcomes are awaited.

OBJECTIVE: Pelvic fractures in older adults are a major public health problem and socioeconomic burden. The standard of care has changed over the past years, and there is limited consensus on which patients benefit from surgical fixation. There is currently no nationwide treatment protocol to guide the decision-making process. Therefore, the aim of this survey was to provide more insight into if, when, and why patients with a fragility fracture of the pelvis (FFPs) would be considered for additional imaging and surgical fixation by treating physicians.
METHODS: An online clinical vignette-based survey of hypothetical scenarios was sent out to all orthopedic and trauma surgeons in the Netherlands. The questionnaire comprised multiple-choice questions and radiographic images. Differences between subgroups were calculated using the X2 test or the Fisher exact test.
RESULTS: 169 surgeons responded to the survey, with varying levels of experience and working in different types of hospitals. In a patient with a simple pubic ramus fracture and ASA 2 or ASA 4, 32% and 18% of the respondents would always advise a CT scan for further analysis. In the same patients, 11% and 31% of the respondents would not advise a CT scan, respectively. When presented with three cases of increasing severity of co-morbidity (ASA) and/or increasing age and/or different clinical presentation of an FFP type 3c on a CT scan, an increasing number of respondents would not consider surgical fixation. There was significant variation in practice patterns between the respondents who do not work in a hospital performing pelvic and acetabular (P&A) fracture surgery and those who do work in a P&A referral hospital. Most respondents (77%) refer patients 1-5 times a year to an expert center for surgical fixation.
CONCLUSIONS: There is currently a wide variety of clinical practices regarding the imaging and management of FFPs, which seems to be influenced by the type of hospital the patients are presented to. A regional or national evidence-based treatment protocol should be implemented to ensure a more uniform approach.

A 67-year-old woman was referred to our hospital for further evaluation of a positive fecal occult blood test. Colonoscopy revealed an elevated rectal lesion (10 mm in size) with a central depression. A rod-like object was noted in the center of the lesion. Magnifying endoscopy with narrow-band imaging showed obscure surface structures and dilated vessels. Magnifying endoscopy with crystal violet staining showed that the pit pattern had disappeared. These endoscopic findings suggested that the lesion was comprised of granulation tissue. A detailed medical history revealed that she had undergone a total hysterectomy with mesh placement for bladder prolapse. We reasoned that the mesh used during pelvic surgery might have penetrated the rectum. She underwent subsequent surgery to remove the mesh. Although most foreign bodies in the rectum are swallowed or self-inserted, pelvic surgery is another source of foreign bodies in the rectum.
