In Switzerland, approximately 32,000 patients are hospitalized annually due to adverse drug reactions (ADRs), representing 2.3% of all hospitalizations. During the perioperative period, the administration of a variety of drugs from different classes over a relatively short period of time increases the risk of ADR. Here, we describe the case of a 32-year-old woman who was administered droperidol to treat nausea in the recovery room after a myomectomy and who subsequently became comatose. Correctable metabolic, respiratory, and cerebrovascular disorders were ruled out. Six hours after the event, she was extubated without residual effects. We discuss potential ADR for droperidol.

OBJECTIVE: To evaluate the use of dilute carboprost tromethamine injection at the endometrium/myoma junction during hysteroscopy to facilitate myoma expulsion and removal in a single procedure.
METHODS: Case series.
METHODS: Single high-volume academic medical center.
METHODS: Seven patients aged 32 to 51 years old with FIGO type 2 uterine myomas and symptoms of abnormal uterine bleeding or infertility undergoing hysteroscopic resection with a morcellation device from November 2022 to July 2023.
METHODS: Dilute injection of carboprost tromethamine (10 µg/mL) at time of hysteroscopic myomectomy.
RESULTS: The main outcome measure was ability to complete the hysteroscopic myomectomy in a single procedure using a hysteroscopic morcellator. Secondary outcomes included total operative time, fluid deficit, and postoperative pharmacologic side effects and/or surgical complications. Among our 7 patients, all had successful single procedure complete resections of myomas ranging from 0.9 to 4.6 cm in maximal diameter. Average operative time was 30 minutes, and average fluid deficit was approximately 839 mL. The carboprost dosages used ranged from 30 to 180 µg. One patient experienced prolonged postoperative nausea and vomiting that resolved with antiemetics. One patient experienced postoperative endometritis that improved with antibiotics.
CONCLUSIONS: In this pilot study, injection of dilute carboprost intraoperatively facilitated one-step hysteroscopic myomectomy of FIGO 2 myomas, via enhanced extrusion of the intramural portion of the fibroid into the uterine cavity, with both short operative times and acceptable fluid deficits.

BACKGROUND: Cellular uterine leiomyomas (CL) represent the prevailing subtype among uterine leiomyomas. In this study, we report a case of recurrent peritoneal disseminated uterine fibroids 2 years after single-port laparoscopic gasless myomectomy. This article endeavors to examine the potential limitations of the aforementioned surgical procedure and outline the distinguishing features of recurrent cases with primary postoperative pathology as CL. Additionally, it aims to provide a summary of previous retrospective studies on CL and propose the existence of immunohistochemical molecules that may serve as predictors for the postoperative recurrence of cellular uterine fibroids. The ultimate objective is to enhance clinicians\' comprehension of the disease.
METHODS: Two years ago, the patient underwent a single-port gasless laparoscopic myomectomy for uterine fibroids. Gynecological color Doppler ultrasound conducted 3 months ago revealed recurrence of uterine fibroids, and the patient experienced abdominal distension, mild urinary frequency, and constipation for the past month.
METHODS: After the second surgical procedure, a comprehensive pathological examination and immunohistochemical analysis of both the uterine mass and metastatic lesions revealed that the definitive diagnosis was CLs.
METHODS: The patient underwent the total hysterectomy, bilateral salpingectomy, pelvic adhesiolysis, omental mass resection, mesenteric mass resection, and pelvic peritoneal mass resection. All specimens were sent for rapid frozen examination and showed to be leiomyomas.
RESULTS: The patient was discharged from the hospital on the 10th day after the operation. At the date of writing the article, the patient had no recurrence for 1 year and 5 months.
CONCLUSIONS: The single-port gasless approach did not achieve the desired reduction in fibroid recurrence, as anticipated by the surgeon. The act of pulling the tumor towards the abdominal incision for resection, on the contrary, may serve as an iatrogenic factor contributing to postoperative recurrence of CL into peritoneal dissemination leiomyomatosis. The single-port gasless assisted bag may be a more suitable option for myomectomy. The utmost effort should be made to prevent the potential recurrence of myoma caused by iatrogenic factors.

BACKGROUND: Uterine abscess is a rare gynecologic entity and only a few cases have been reported so far. This study aimed to describe our clinical experience in this case. Initially, hematoma was diagnosed without detail previous medical record. Finally, laparotomy was performed due to refractory fever and highly possible diagnosis of uterine abscess. We successfully performed a hysterectomy and the patient had an uneventful recovery.
METHODS: A 44-year-old nulliparous woman underwent myomectomy in the local hospital, 45 days ago. She complained of irregular fever (up to 40 °C) without abdominal pain since the surgery.
METHODS: Due to lack of her detail medical record, equivocal images and her strong intention to preserve uterus, she was misdiagnosed with hematoma and treated with antibiotic treatment. Finally, intraoperative findings revealed that the huge myometrial abscess contained a mass of pus.
METHODS: Laparotomy was performed due to refractory high-grade fever and highly possible diagnosis of uterine abscess. Total hysterectomy was performed to avoid the possibility of life-threatening sepsis.
RESULTS: The postoperative course was uneventful and the patient was discharged 10 days after surgery.
CONCLUSIONS: Complete imaging examinations are recommended prior myomectomy to facilitate the differential diagnosis of postoperative complications. In addition, several measures, such as maintaining aseptic conditions during surgery and postoperative drainage, play a critical role in preventing nosocomial infections. Rare uterine abscess is often mistaken for hematoma with fever. If the patient develops high fever after myomectomy, accompanied by a mass in the myometrium, the possibility of infection or even abscess formation should not be excluded. For women who need to preserve their fertility, the early diagnosis and timely administration of appropriate medication is crucial for preventing uterine loss.

Hemoglobin M (Hb M) is a group of abnormal Hb variants that form methemoglobin, which leads to cyanosis. Patients with Hb M appear cyanotic but are usually asymptomatic. Cyanosis with low peripheral oxygen saturation is unresponsive to oxygen therapy despite normal partial pressure of oxygen. As such, close attention should be paid during anesthesia. We report the first case of a Hb M patient undergoing laparoscopic uterine myomectomy under general anesthesia.

Hysteroscopy is an exploratory endoscopic technique that studies the interior of the uterine cavity and the endocervical canal. Various fluids, such as physiological saline, are used to optimise visualisation of the internal structures during this procedure. A rare complication of hysteroscopy is fluid overload, which can be associated with intravascular absorption syndrome, usually after lengthy procedures or tissue dissection. There are no data on the incidence and prevalence of this syndrome, and few cases involving physiological saline solution have been reported. We present a case of hysteroscopic myomectomy complicated by vascular absorption syndrome, which gave rise to acute pulmonary oedema that required admission to the intensive care unit.

We present the unique case of a 44-year-old gravida 3 para 2 woman with complaints of monolateral perception of fetal movements who underwent elective cesarean section and hysterectomy for the presence of an exceptionally voluminous infralegamentary leiomyoma. Cesarean section required in-depth preoperative planning and was possible only after gravid uterus exteriorization. Myomectomy and hysterectomy were then necessary to reestablish the physio-anatomical pelvic environment. The patient was discharged after regular and uncomplicated postoperative time. In recent years, the paradigma of avoiding cesarean myomectomy due to fear of hemorrhage has been questioned by many authors and in certain cases cesarean myomectomy may even be undeferrable. We describe an innovative surgical technique which could be useful to obstetricians approaching similar uterine masses during cesarean sections.

A uterine diverticulum is defined as the presence of a niche within the inner contour of the uterine myometrial wall. Although secondary uterine diverticula can occur after hysterotomy such as cesarean section, reports of diverticula after myomectomy are extremely rare.
A 45-year-old nulliparous woman undergoing infertility treatment was referred to our hospital because of abnormal postmenstrual bleeding after myomectomy. Transvaginal sonography and magnetic resonance imaging revealed a diverticulum in the isthmus. Fat-saturated T1 image showed a blood reservoir in the diverticulum. Hysteroscopic surgery was performed to remove the lowed edge of the defect and coagulate the hypervascularized area. Two months after surgery, the abnormal postmenstrual bleeding and chronic endometritis improved.
This report highlights the similarities of the patient\'s diverticulum to cesarean scar defects in terms of symptoms and pathophysiology. First, this patient developed a diverticulum with hypervascularity after myomectomy and persistent abnormal bleeding. Second, after hysteroscopic surgery, the symptoms of irregular bleeding disappeared. Third, endometrial glands were identified within the resected scar tissue. Fourth, preoperatively identified CD138-positive cells in endometrial tissue spontaneously disappeared after hysteroscopic resection. To the best of our knowledge, this is the first report of symptomatic improvement following hysteroscopic surgery in a patient with an iatrogenic uterine diverticulum with persistent irregular bleeding after myomectomy.

Uterine diverticulum is classified into congenital and acquired types. The acquired type is caused by caesarean scar syndrome, which occurs after caesarean section. There are no detailed reports on diverticulum after enucleation of uterine fibroids. Most cases are treated with hysteroscopy or laparoscopy, but a management consensus is lacking. We treated a patient with a uterine diverticulum that had formed after uterine fibroid enucleation by combining hysteroscopic and laparoscopic treatments.
The patient was a 37-year-old Japanese woman, G1P0. A previous doctor had performed abdominal uterine myomectomy for a pedunculated subserosal uterine fibroid on the right side of the posterior wall of the uterus near the internal cervical os. Menstruation resumed postoperatively, but a small amount of dark-red bleeding persisted. MRI two months after the myomectomy revealed a diverticulum-like structure 3 cm in diameter, communicating with the uterine lumen, on the right side of the posterior wall of the uterus. Under suspicion of uterine diverticulum after uterine fibroid enucleation, the patient sought treatment at our hospital approximately four months after the myomectomy. Through a flexible hysteroscope, a 5-mm-diameter fistula was observed in the posterior wall of the uterus, and a contrast-enhanced pocket, measuring approximately 3 cm, was located behind it. Uterine diverticulum following enucleation of a uterine fibroid was diagnosed, and surgery was thus deemed necessary. The portion entering the fistula on the internal cervical os side was resected employing a hysteroscope. Intra-abdominal findings included a 4-cm mass lesion on the posterior wall on the right side of the uterus. The mass was opened, and the cyst capsule was removed. A 5-mm fistula was detected and closed with sutures. Resuturing was not performed after dissection of the right round ligament due to tension. The postoperative course has been good to date, with no recurrence.
Uterine diverticula after myomectomy may be treated with a combined laparoscopic and hysteroscopic approach, similar to caesarean scar syndrome.

BACKGROUND: Omental Infarction (OI) is uncommon and mimics common causes of acute abdomen. It is important to differentiate it from other abdominal conditions that require emergency management. It was first reported in literature in 1896 and about 400 cases have been reported till date.
METHODS: We reported on a 41 year-old Para 0+0 Ibo house wife who presented with 10 years history of supra-pubic mass and five months history of excessive menstrual flow. After physical examination, a diagnosis of symptomatic uterine fibroid was made. She had myomectomy and the raw surface created after the excision of the myomas was covered with omentum. Wound infection developed on the 8th post-operative day leading to a wound breakdown and later partial extrusion of infarcted omental tissue through the dehisced wound. During re-exploration, the infarcted omental tissue was extracted and the residual abdominal abscess was drained. Surgical site wound infection occurred on the 3rd day after re-operation and a sub-acute intestinal obstruction developed on the 4th day thereafter which responded to conservative management.
CONCLUSIONS: Careful surgical technique is imperative when utilizing the omentum for reconstructive abdominal surgery. Torsion of the omentum and creation of excess tension while using the omentum for reconstructive procedures should be avoided and increase awareness of this uncommon disease condition by the surgeon is also important. This case is to report a rare finding of omental infarction following myomectomy.
