A comparative retrospective analysis on robot-assisted laparoscopic surgery compared to conventional laparoscopy in case of myomectomy: experience in a third-level hospital of Southern Italy.

Uterine myomas are the most common gynecological disease in reproductive-aged women, present several symptoms, and require effective medical and/or surgical strategies. This study aimed to compare robotic-assisted laparoscopic myomectomy (RALM) with laparoscopic myomectomy (LM) in terms of operative times, intraoperative estimated blood loss, pre- and post-hemoglobin levels drop, and length of hospital stay. Data from 50 clinical records (25 RALM in Group A and 25 LM in Group B) of patients with uterine fibroids were collected from December 2022 to December 2023 at Gynecological Unit of DAI Materno-Infantile Federico II in Naples, Italy. Patients aged 30-49 years with symptomatic fibroids were included. Data on peri-operative outcomes, including operative time for myomectomy (OTM), overall operative time (OOT), intraoperative estimated blood loss (EBL), pre- and post-operative hemoglobin levels, and length of hospital stay were analyzed. The OTM in the presence of > 5 myomas was 59 [52-65] vs 69 min [61-96] (p < 0.001) for RALM and LM groups, respectively. Moreover, also in presence of ≤ 5 myomas, a difference was observed in the RALM group 48[43-55] compared to the LM group 53[50-61] min (p = 0.07). The OOT was also statistically significant for Group A compared to Group B (83[65-93] vs 72[56-110] min, p < 0.001). There were no significant differences between the two groups in terms of pre- and post-operative hemoglobin levels and EBL (p = 0.178). Group A demonstrated a notably shorter hospital stay 1.2 [1-2] days compared to Group B 2.9[3-3.75] days (p = 0.007). Our study suggests potential advantages of RALM over LM in terms of reduced operative times and shorter hospital stays. The standardized approach and extensive surgical experience likely contributed to the favorable outcomes of RALM.

Laparotomic versus robotic surgery in elderly patients with endometrial cancer: A systematic review and meta-analysis.

BACKGROUND: Although robotics has been shown to improve outcomes in some high-difficulty surgical category patients, it is unclear if such an approach may improve outcomes in elderly patients with endometrial carcinoma (EC). OBJECTIVE: To compare robotic and laparotomic surgery in the treatment and staging of elderly EC patients. MATERIALS AND METHODS: A systematic review and meta-analysis was performed assessing the risk of overall, intra-operative, and peri-operative complications associated with the surgical approach (laparotomic vs robotic) for elderly patients with EC by relative risk (RR). Pooled means ± standard deviation of length of stay were compared with the unpaired t test. Subgroup analyses for overall complications were performed based on different age cut-offs (>70, >65, and >75 years) and severity of complications (minor and major). A value of P less than 0.05 was considered significant. RESULTS: Five studies with 7629 EC patients were included. Pooled RR for robotic compared with laparotomic surgery was 0.40 (P < 0.001) for overall, 0.46 (P = 0.18) for intra-operative, and 0.43 (P < 0.001) for peri-operative complications. Pooled difference between means ± standard deviation of length of stay for robotic versus laparotomic surgery was -3.34 (P < 0.001). At subgroup analyses, pooled RR of overall complications for robotic surgery versus laparotomic surgery was 0.34 (P < 0.001) in the >70 years, 0.51 (P < 0.01) in the >65 years, 0.20 (P = 0.12) in the >75 years groups. Pooled RR was 0.50 (P = 0.1) in the minor complications subgroup, and 0.42 (P = 0.002) in the major complications subgroup. CONCLUSION: Robotics might be a viable alternative to the laparotomic approach for EC in elderly patients because it significantly decreases the risk of overall and peri-operative complications (mainly major complications), and the length of stay when compared with laparotomy. The decrease in risk of overall complications is greater with increasing patient age.

Combined hysteroscopic findings and 3-dimensional reconstructed coronal view of the uterus to avoid laparoscopic assessment for inpatient hysteroscopic metroplasty: pilot study.

STUDY OBJECTIVE: To assess the use of 3-dimensional (3D) reconstructed coronal view of the uterus and intraoperative hysteroscopic findings to avoid diagnostic laparoscopy during inpatient hysteroscopic metroplasty. DESIGN: Pilot study (Canadian Task Force classification II). SETTING: University hospital infertility clinic. PATIENTS: Fifty-nine patients with recurrent abortion and double uterine cavity with 3D sonographic diagnosis of septate uterus undergoing inpatient hysteroscopic metroplasty. INTERVENTIONS: Inpatient hysteroscopic treatment of septate uterus without laparoscopic diagnosis. In addition to sonographic observations, 2 intraoperative hysteroscopic criteria were used to confirm the diagnosis: visualization of muscular fibers and myometrial blood vessels. MEASUREMENTS AND MAIN RESULTS: Operative parameters (operative time and fluid absorption), complications (incomplete resection and uterine perforation), requirement for a second intervention, and shape of the uterine cavity at hysteroscopic follow-up. In 56 of 59 patients (94.9%), intervention was performed without complications, and in 3 cases, intervention was suspended because of intraoperative suspicion of bicornate uterus. These 3 patients underwent laparoscopy, which confirmed the diagnosis of septate uterus. In all cases, incision was considered sufficient. Postoperative diagnostic hysteroscopy in all patients showed a normal cavity (fundal notch <1 cm). CONCLUSIONS: Combined use of hysteroscopic confirming criteria and 3D sonography seems to be a reliable and simple strategy for characterizing the presence of septate uterus and to perform inpatient metroplasty usually without laparoscopic visualization of the uterine fundus.

Relationship between morular metaplasia and squamous differentiation in endometrial carcinoma.

Morular metaplasia (MM) is a peculiar type of metaplastic change commonly observed in endometrial lesions, which is defined by the absence of overt squamous features and a characteristic immunophenotype. The nature of MM and its relationship with conventional squamous differentiation (SD) is still undefined. Here, we present a morphological and immunophenotypical study of cases with mixed MM/SD and conventional SD, providing new insights on this field. Twenty cases of endometrioid carcinoma (10 with mixed MM and SD and 10 with conventional SD) were assessed by immunohistochemistry for ß-catenin, CD10, CDX2, ki67, p63, p40, estrogen receptor (ER), progesterone receptor (PR) and cytokeratins (CK) 5/6, 7, 8/18 and 19. In mixed MM/SD cases, SD was mostly located within the MM areas; several degrees of SD development were observed within MM, from cells with larger cytoplasm and prominent membrane, to overt SD with morular shape and ghost cell keratinization. In the MM→SD transition, there was progressive loss of nuclear ß-catenin, CD10, CDX2 and CK8/18 expression, increase of CK5/6 and CK7 expression, and stable CK19 positivity. ER, PR and ki67/MIB1 expression was low-to-negative in both MM and SD. The squamous cell markers p63 and p40 were mostly expressed at the interfaces between MM and SD. Conventional SD cases showed direct transition from glandular epithelium to SD with a surface growth and no ghost cell keratinization; immunohistochemistry showed strong positivity for ER, PR and all CKs, basal positivity for p63, p40 and ki67/MIB1, negativity for nuclear ß-catenin, CD10 and CDX2. In conclusion, MM appears as the precursor of a peculiar form of SD, which differs morphologically and immunophenotypically from conventional SD. Defining MM based on the absence of overt squamous might not be meaningful. Further studies are necessary to clarify the nature of MM.

Robotic Hysterectomy as a Step of Gender Affirmative Surgery in Female-to-Male Patients.

INTRODUCTION: To evaluate the feasibility and safety of robotic hysterectomy in the "transgender male/non-conforming" population and the short and long-term surgical outcomes of robotic surgery in these patients. MATERIALS AND METHODS: A retrospective analysis was carried out from February 2016 to January 2018. Twenty female transgender patients with a previous psychiatric diagnosis of gender dysphoria who did not present genital pathologies were included in the study. The robotic hysterectomies were performed from June 2016 to March 2018 using a Da Vinci Xi Robot (Intuitive Surgical, Sunnyvale, CA, USA). RESULTS: No intraoperative or postoperative complications were recorded. The median duration of the intervention was of 90 minutes, including docking which lasted 16 minutes, while the median stay in the operating room was of 140 minutes. The median time of duration of intervention was of 90 minutes. The median blood loss was about 90 ml with a percentage decrease in hemoglobin between pre- and post-operative of about 8%. Postoperative pain was assessed using the VAS scale in the immediate postoperative period, on the first and second day, resulting of 3 and 2, respectively. The pathological examination of surgical specimens confirmed the absence of malignancy. CONCLUSIONS: The robotic approach represents a feasible, safe, and effective surgical option for hysterectomy for "transgender male" affected by gender dysphoria.

Stanford parameters stratify the risk of recurrence in gynecologic smooth muscle tumors of uncertain malignant potential.

Smooth muscle tumor of uncertain malignant potential (STUMP) is an ill-defined category of neoplasms, which represent a diagnostic challenge. We aimed to assess whether the Stanford parameters, that is, high mitotic index (≥10/10HPF), significant atypia (moderate-to-severe), and coagulative tumor cell necrosis (CTCN), even when focal or ambiguous, may be used to stratify the risk of recurrence in gynecological smooth muscle tumor of uncertain malignant potential (STUMP). Electronic databases were searched from their inception to October 2019. All studies assessing the Stanford parameters in gynecological STUMP series were included. STUMPs were subdivided according to the presence of the three Stanford parameters: high mitotic index, significant atypia, and CTCN. A Kaplan-Meier survival analysis was performed for recurrence-free survival; hazard ratio (HR) was calculated in each category. Fourteen studies with 219 STUMPs were included. In 15.5% of cases, none of the three Stanford parameters were present, with a recurrence risk of 5.9%; 2.7% of cases showed high mitotic index alone, with a recurrence risk of 0% (HR = not calculable); 43.8% of cases showed significant atypia alone, with a recurrence risk of 18.7% (HR = 3.3; p = 0.012); 26.5% of cases showed CTCN alone, with a recurrence risk of 17.2% (HR = 3.1; p = 0.029); and 11.4% of cases showed at least two Stanford parameters, with a recurrence risk of 32% (HR = 7.5; p = 0.003). Stanford parameters may stratify the risk of recurrence of STUMP. Significant atypia and CTCN, but not high mitotic index, may be stand-alone risk factors for recurrence in STUMP. The presence of at least two Stanford parameters, even if equivocal (e.g., uncertain or focal CTCN, focal significant atypia, mitotic index around 10/10HPF), might still be enough to support a diagnosis of leiomyosarcoma. Further studies are necessary in this field.

Endometrial polyps in infertile patients: do high concentrations of interferon-gamma play a role?

OBJECTIVE: To assess levels of interferon-gamma (IFN-γ) both in serum and in endometrial biopsy samples from infertile patients with endometrial polyps, to investigate the molecular background involved in the formation of endometrial polyps and its potential role in infertility. DESIGN: Prospective controlled trial. SETTING: Academic infertility clinic. PATIENT(S): Twenty-one infertile women affected by endometrial polyposis represented the study group, and 21 homogeneous women without endometrial polyps were enrolled as control subjects. INTERVENTION(S): Blood and endometrial biopsy collection from infertile women with and without endometrial polyps. MAIN OUTCOME MEASURE(S): IFN-γ-positive cells were analyzed and counted as spot-forming colonies. RESULT(S): IFN-γ levels were significantly higher both in serum and in tissue biopsies of women with endometrial polyps. CONCLUSION(S): High concentrations of IFN-γ were detected in infertile patients with endometrial polyps. The possible role of an inflammatory factor in a proliferative pathology represents a novel insight into the understanding of endometrial polyposis and its relationship with infertility.

Are we underutilizing Palmer's point entry in gynecologic laparoscopy?

OBJECTIVE: To report our experience using Palmer's point entry in women undergoing gynecologic laparoscopic surgery. DESIGN: Retrospective observational study. SETTING: University teaching hospital, London, United Kingdom. PATIENT(S): We reviewed all patients who underwent laparoscopic gynecologic surgery under the care of the senior author between January 1, 2005, and December 31, 2008. INTERVENTION(S): Gynecologic laparoscopic surgery. MAIN OUTCOME MEASURE(S): Indications, incidence, success, and complications of using Palmer's entry. RESULT(S): Three hundred eighty-five patients underwent laparoscopic surgery. We used umbilical entry in 249 (64.6%) and Palmer's entry in 136 (35.4%). In almost three fourths of cases, the indications for using Palmer's point were previous laparotomy or the presence of large uterine fibroids. The next most common reasons for choosing Palmer's point were known documentation of intra-abdominal adhesions from prior laparoscopies, large ovarian cysts, and hernias or hernia repairs. Entry via Palmer's point was successful in all but two cases (98.5%), and there were no entry-related complications. CONCLUSION(S): Our experience shows that laparoscopic entry using the left upper quadrant is safe with a low failure rate. Because the vast majority of gynecologic laparoscopies are done using subumbilical entry, it seems that Palmer's entry is underused by many gynecologists, despite it being safer in patients at risk of underlying adhesions and more appropriate in the presence of a large pelvic mass or a nearby hernia.
