Retrospective analysis of secondary resection of the cervical stump after subtotal hysterectomy: why and when?

Purpose The rates of hysterectomy are falling worldwide, and the surgical approach is undergoing a major change. To avoid abdominal hysterectomy, a minimally invasive approach has been implemented. Due to the increasing rates of subtotal hysterectomy, we are faced with the following questions: how often does the cervical stump have to be removed secondarily, and what are the indications? Methods This was a retrospective, single-centre analysis of secondary resection of the cervical stump conducted from 2004 to 2018. Results Secondary resection of the cervical stump was performed in 137 women. Seventy-four percent of the previous subtotal hysterectomy procedures were performed in our hospital, and 26% were performed in an external hospital. During the study period, 5209 subtotal hysterectomy procedures were performed at our hospital. The three main indications for secondary resection of the cervical stump were prolapse (31.4%), spotting (19.0%) and cervical dysplasia (18.2%). Unexpected histological findings (premalignant and malignant) after subtotal hysterectomy resulted in immediate (median time, 1 month) secondary resection of the cervical stump in 11 cases. In four patients, the indication was a secondary malignant gynaecological disease that occurred more than 5 years after subtotal hysterectomy. The median time between subtotal hysterectomy and secondary resection of the cervical stump was 40 months. Secondary resection of the cervical stump was performed vaginally in 75.2% of cases, laparoscopically in 20.4% of cases and abdominally in 4.4% of cases. The overall complication rate was 5%. Conclusion Secondary resection of the cervical stump is a rare surgery with a low complication rate and can be performed via the vaginal or laparoscopic approach in most cases. The most common indications are prolapse, spotting and cervical dysplasia. If a secondary resection of the cervical stump is necessary due to symptoms, 66.6% will be performed within the first 6 years after subtotal hysterectomy.

Sentinel Lymph Node Mapping in Endometrial Cancer after Supracervical Hysterectomy

Background Occult endometrial cancer after supracervical hysterectomy is uncommon. Even if optimal management of those rare cases is still unproven, to guide the need for adjuvant treatment, restaging should be recommended in this situation. Methods The study was approved by institutional review board (DIPUSVSP-27-07-20107). We report the case of a 52-year-old woman with occult grade 2 endometrioid endometrial adenocarcinoma (pT1a) with negative surgical margin and smooth uterine muscle of uncertain malignant potential after supracervical hysterectomy and bilateral salpingo-oophorectomy performed for pelvic pain and uterine fibroids in a local hospital. Preoperative CT scan of chest-abdomen-pelvis did not show any lymphadenopathy or distant metastasis. Pelvic US scan revealed a normal cervical stump and a hypoechoic 18-mm right parametrial nodule. We describe the feasibility of laparoscopic sentinel lymph node identification with cervical stump injection of indocyanine green. Results The patient underwent laparoscopic radical trachelectomy, left pelvic sentinel lymph node biopsy, right pelvic lymphadenectomy, peritoneal washing. Patient did not report any intraoperative or postoperative complication. At final histology cervix, SLN (ultrastaging) and pelvic lymph nodes were negative, while parametrial nodule was reported as metastasis from endometrial adenocarcinoma. Surgical margins were clear. Patient was staged as FIGO IIIB and underwent adjuvant chemo-radiation. She is now alive and disease-free, 12 months after the surgery. Conclusions This video (Video 1) underlines the fact that SLN mapping with cervical injection is a feasible and safe technique also without the uterine corpus after supracervical hysterectomy. The unilateral mapping could be due to the presence of metastatic parametrium on the right side.

Cervical stump necrosis after laparoscopic supracervical hysterectomy: successful management by laparoscopic approach

Persistent bleeding from the remaining cervix after laparoscopic supracervical hysterectomy (LSH) is normally related to the presence of residual functioning endometrial tissue. However, postoperative significant vaginal hemorrhage caused by cervical necrosis following LSH is relatively rare. A 39-year-old nulligravida was admitted to the emergency department with hypovolemic shock after LSH performed in another hospital for treatment of uterine fibroids 18 days previously. Following hemodynamic stabilization and mechanical tamponade of the bleeding uterine cervix, laparoscopic simple trachelectomy was carried out and antibiotics were administered. The patient developed no surgical or clinical complications and was discharged 4 days after surgery. Histologic examination revealed extensive areas of tissue necrosis and no signs of malignancy. Stump necrosis and accompanying bleeding are rare but serious complications of LSH. Infection is an important component of this entity and should be treated. Endoscopic management of this condition appears to be feasible and safe.

Characteristics, complications, and outcomes of early-stage cervical stump carcinoma: laparoscopy versus laparotomy

Objective To compare the characteristics, surgical complications, and overall survival between patients undergoing laparoscopy versus laparotomy for treatment of early-stage cervical stump carcinoma. Methods Patients with International Federation of Gynecology and Obstetrics (FIGO, 2009) stage IA2 to IIA2 cervical stump carcinoma who underwent laparoscopy or laparotomy in the Obstetrics and Gynecology Hospital of Fudan University from January 2000 to June 2018 were retrospectively reviewed. All patients’ clinical characteristics, pathological features, complications, and follow-up data were retrieved. Results Seventy-two patients were included in the analysis; 58 underwent laparoscopy and 14 underwent laparotomy. With respect to surgical complications, laparoscopy was associated with a significantly lower complication rate, less blood loss, a shorter operative time, and a higher hospitalization fee than laparotomy. Survival was not significantly different between the laparoscopy and laparotomy groups. Conclusions Although survival was not significantly different between the two surgical approaches, the rate of surgical complications was much lower in the laparoscopy than laparotomy group.

Stump Pyometra Secondary to Human Topical Estrogen Hormone Exposure in a Spayed Female Chihuahua

ABSTRACT A 6 yr old female spayed Chihuahua was presented for evaluation of intermittent vulvar discharge, stranguria, and vomiting. This dog had an ovariohysterectomy as a puppy and did not experience any evidence of estrous until 4.5 yr later. The owner had been using a topical hormone replacement therapy (estradiol spray) twice daily for the duration of the dog’s clinical signs of 1 yr. On presentation, the dog had truncal alopecia, comedones, enlarged vulva with a malodorous, and purulent discharge. Bloodwork showed a leukocytosis with a neutrophilia, döhle bodies, and moderate toxic changes. An abdominal ultrasound revealed an enlarged uterine stump with a thickened wall, ovoid projection cranially, and echogenic luminal contents. An exploratory laparotomy identified an enlarged cervical stump. Histopathology revealed chronic suppurative vaginitis with endometritis, necrosis, and intraluminal coccoid bacteria. The dog recovered well from surgery. A baseline estrogen level post operatively was measured at 56.4 pg/mL (<50.0 pg/mL for a spayed bitch), at this time, the dog had been separated from the owner for 7 days. After surgery, the clinical signs disappeared, and the dog’s dermatologic changes improved. This is the first reported case of stump pyometra following exposure to the owner’s topical estradiol replacement medication.
