Mioma en remanente cervical tras histerectomía supracervical laparoscópica, presentación de un caso y revisión de la literatura / Myoma in cervical remnant after laparoscopic supracervical hysterectomy, case report and literature review

INTRODUCCIÓN: Los leiomiomas uterinos son el tumor pélvico más frecuente en la mujer, derivan de las células musculares lisas del miometrio y pueden localizarse en cualquiera de las porciones uterinas. Se clasifican según su relación con las diferentes capas del útero mediante la clasificación de la FIGO. Pueden ser asintomáticos o producir síntomas como sangrado, problemas reproductivos o dolor por compresión de estructuras vecinas. El tratamiento puede ser médico o quirúrgico, teniendo dentro de este último grupo, la posibilidad de realizar una miomectomía o una histerectomía total o subtotal. La histerectomía subtotal permite mantener el cérvix uterino, de tal forma que la técnica quirúrgica es más sencilla, sin embargo, requiere de la morcelación de la pieza para su extracción; mientras que la histerectomía total elimina el riesgo de recidiva de la patología uterocervical, aunque precisa de una mayor curva de aprendizaje. CASO CLÍNICO: Presentamos el caso de una paciente de 52 años a la que se le realizó una histerectomía supracervical laparoscópica por miomas. Posteriormente, se objetivó la aparición de un nuevo mioma en el remanente cervical, que requirió de una traquelectomía vía vaginal. CONCLUSIÓN: La histerectomía subtotal laparoscópica en úteros con múltiples miomas puede tener como efecto adverso la recidiva miomatosa en el cérvix o la aparición de miomas parasitarios secundarios a la morcelación uterina no estanca. Además, implica continuar con el cribado para la prevención del cáncer de cérvix uterino.

BACKGROUND: Uterine leiomyomas are the most frequent pelvic tumor in women. They derive from smooth muscle cells of the myometrium and can be in any of the uterine parts. They are classified according to their relationship with the different layers of the uterus by the FIGO classification. Uterine leiomyomas can be asymptomatic or produce symptoms such as compression pain, reproductive problems and metrorrhagia. The treatment can be medical or surgical. Within this last group there is the possibility of performing a myomectomy or a total or subtotal hysterectomy. The subtotal hysterectomy allows the uterine cervix to be maintained and therefore the surgical technique is simpler. However, it requires the morcellation of the piece for its removal. Alternatively, total hysterectomy eliminates the risk of recurrence of uterocervical pathology, but this procedure presents a steeper learning curve. CLINICAL CASE: We present the case of a patient of 52 years who underwent a laparoscopic supracervical hysterectomy for myomas. Subsequently, the appearance of a new myoma in the cervical remnant was observed, which required a vaginal trachelectomy. CONCLUSION: Laparoscopic subtotal hysterectomy in myomatous uterus can have as an adverse effect myomatous recurrence in the cervix or the appearance of parasitic myomas secondary to non-contained uterine morcellation. In addition, it involves continuing screening for the prevention of cervical cancer.

Laparoscopic excision of large omental cyst at department of pediatric surgery in Sanglah general hospital, Bali, Indonesia

Omental cyst is rare. All conditions most likely being of congenital or benign neoplastic lymphatic origin. Patients with Omental cysts usually present with abdominal distention and a painless abdominal mass. The most common physical finding of an omental cyst is a freely movable abdominal mass. The diagnostic procedure include CT scans. Complete excision by open or laparoscopically of the cysts is considered as the treatment of choice. Recurrence and malignant deterioration of omental cysts are rare. A case report of a large omental cyst which had been laparoscopically-treated using morcellator. Laparoscopic morcellation  is a technique used in gynecological surgeries such as hysterectomy and myomectomy to remove uteri and uterine fibroids (leiomyomas) through a small abdominal incision. Authors present a case of 3 year old female with pre-operative assessment tumor intra-abdominal suspect abdominal cyst. Subsequently, laparoscopic resection of omental cyst with morcellator was performed. The histopathological report was omental cyst. Omental cysts are rare, but can be shown to have atypical abdominal symptoms and radiologic findings, so clinicians must keep in mind that omental cysts causing abdominal symptoms can be misdiagnosed as simple ovarian cysts of inflammation. Omental cysts can be removed safety laparoscopically with morcellator without bowel or vessel injury.

Myomectomy for uterine preservation and fertility

Background: Leiomyomas are benign monoclonal smooth muscle tumors that are characterized by cellular mutations, growth factor dysfunction, and abnormalities in the extracellular matrix. The objective of this study was to analyse the patient selection, feasibility, complications and the outcomes of myomectomies done for uterine preservation and fertility.Methods: Out of 606 myomectomies performed over 23 years at a tertiary care endoscopy centre, retrospective analysis of 358 cases of laparoscopic myomectomy (LM) and 96 cases of abdominal myomectomy (AM) was done.Results: Myomectomies were done for symptomatic women who wanted to preserve their uterus either to improve fertility or pregnancy outcome. Sizes of myomas tackled by myomectomy ranged from 1 cm to 20 cms. The largest number removed by laparoscopy was 19. 9 out of 358 cases scheduled for LM were converted to AM. 6 patients had repeat myomectomy of myomas. About 0.44% had STUMP and 0.44% had leiomyosarcoma on HPE. Only 10/199 or 5% of patients who wanted to preserve their uterus had subsequent hysterectomies. 95% were satisfied with good symptom relief. 40.1% in LM and 37% in AM group conceived.Conclusions: Majority of the cases were successfully done by laparoscopy. With increasing experience more cases with bigger and multiple myomas could be tackled by laparoscopy. 10.3% in LM and 45.9% in AM were 10 cms-20 cms. The main method of retrieval was morcellation. There were no major complications. Both the methods were found to be safe, feasible and provided good result. With increasing experience bigger and multiple myomas could be tacked by LM, which has several advantages over AM.

A Novel Technique of Morcellation Using a Pneumovesicum After Holmium Laser Enucleation of the Prostate in Complicated Situations: Our Initial Experience and Tips / 대한배뇨장애요실금학회지

PURPOSE: To describe our initial experience with a novel method of adenoma retrieval using a pneumovesicum (PNV) after Holmium laser enucleation of the prostate (HoLEP). METHODS: From January 2016 to April 2018, a total of 93 consecutive patients treated with HoLEP were enrolled in this study. For tissue morcellation, we used the PNV morcellation technique for an initial series of 21 patients and the conventional technique (Lumenis VersaCut) for a consecutive series of 72 patients. We compared efficiency and safety between the novel technique and the traditional technique. Subgroup analysis was performed to assess the effectiveness of the current technique in the large prostate (>70 mL). RESULTS: There were significant differences in mean age and prostate volume between the 2 groups. However, there were no significant differences in the baseline characteristics and preoperative parameters in the subgroup analysis of large prostates (>70 mL). The mean morcellation efficiency was higher (8.50±1.94 minutes vs. 1.76±0.45 minutes, P<0.05) and the time of morcellation (7.81±1.25 minutes vs. 34.04±11.14 minutes, P<0.05) was shorter in the PNV group. Moreover, there were no significant differences between groups in hospitalization period (2.62±1.10 days vs. 2.90±1.26 days, P=0.852) and any other postoperative events, including recatheterization, reoperation, clot retention, and urethral stricture (P-value range, 0.194–0.447). In the PNV group, there were some cases of procedure-related complications, including postoperative extravesical leakage (5th case), clot retention (8th case), and recatheterization (9th case). CONCLUSIONS: This method has a higher tissue retrieval efficacy, with the advantage of excellent visibility compared to conventional morcellation. The current method can be applied when a transurethral morcellator is out of order or cannot be used.

Hysteroscopic myomectomy without anesthesia

OBJECTIVE: Scarce literature about myoma removal without anesthesia has been published. The aim of this paper is to evaluate the feasibility of a new alternative for a hysteroscopic myomectomy in a conventional office setting, without need for anesthesia. METHODS: Step-by-step description of the surgical technique has been provided, based on video images. An office hysteroscopy was performed in a Gynecological Endoscopy Department of a tertiary European hospital. RESULTS: A 49-year-old woman was referred for management of severe hypermenorrhea. Consent and approval were received from the patient and the institutional review board, respectively. The introduction of a Truclear® hysteroscopic polyp morcellator of 5.5 mm with optic of 0 degrees into the uterine cavity did not require any kind of anesthesia or cervical dilatation. The use of saline flow helped distend the cavity and identify a submucosal myoma. Under direct vision, a full myomectomy was performed via mechanical energy with continuous cutting movements, without any complication. After the procedure was completed, the excised material was aspirated through the device into a collecting pouch. A successful complete morcellation of a Type-0 submucosal leiomyoma with a polyp morcellator device was performed in an outpatient setting. Good medical results, good tolerance by the patient besides lower surgical risks due to mechanical instead of electrical energy are shown. CONCLUSION: In conclusion, this video demonstrates that a hysteroscopic myomectomy can be performed successfully in office with lower risk of complications from the procedure and without use of general anesthesia besides good tolerance by the patient.

Disseminated peritoneal leiomyomatosis: a devastating sequelae of unconfined laparoscopic morcellation

There has been growing concern surrounding the use of unconfined power morcellation in laparoscopic surgeries for uterine leiomyoma due to its associated risks and long-term clinical sequelae, including parasitic leiomyomas and disseminated peritoneal leiomyomatosis (DPL). We present a case of DPL resulting from previous laparoscopic morcellation and a review of the existing literature. DPL is a potentially devastating consequence of unconfined laparoscopic morcellation in the surgical management of uterine fibroids. A multidisciplinary approach is recommended in the management of DPL, especially in cases of multivisceral involvement. Clinical caution ought to be exercised when using power morcellators; when unavoidable, confined laparoscopic morcellation offers a promising mitigation and should be adopted if practicable.

In-bag power morcellation technique in single-port laparoscopic myomectomy

OBJECTIVE: This study introduces and evaluates the feasibility, safety, and surgical outcomes of the in-bag power morcellation technique during single-port assisted (SPA) laparoscopic myomectomy in comparison with manual scalpel morcellation. METHODS: This is a retrospective review of a total of 58 patients who underwent SPA laparoscopic myomectomy employing in-bag power morcellation (n=27) or manual scalpel morcellation (n=31), performed between December 2014 and December 2016. Surgical outcomes, including total operation time, estimated blood loss, postoperative hemoglobin changes, postoperative hospital stay, postoperative pain (visual analog scale), perioperative and postoperative complications were evaluated. RESULTS: The demographics and patient characteristics were similar between both groups. The median patient age was 34 years and median body mass index was 20.84 kg/m2. The median specimen weight was 110 g. The median operating time was 138 minutes. The median estimated blood loss was 50 mL and the median postoperative hemoglobin change was 2.2 g/dL. The median postoperative hospital stay was 2 days and the median postoperative pain scores were 5 after 6 hours, 3 after 24 hours, and 2 after 48 hours. Occult malignancy was not identified in any patients. There were no intraoperative complications such as LapBag ruptures or gross spillage. CONCLUSION: In-bag power morcellation for SPA laparoscopic myomectomy is feasible and safe, minimizing the risks of open power morcellation. There were also no statistically significant differences in surgical outcomes.

Miomectomía por laparoscopia con extracción por colpotomía posterior: reporte de tres casos / Laparoscopic myomectomy with extraction by posterior colpotomy: Report of three cases

Resumen ANTECEDENTES La extracción de un mioma, posterior a la resección laparoscópica, puede ser: directa, mediante colpotomía posterior, minilaparotomía, morcelación intraabdominal estándar o eléctrica. La mayor parte de estas opciones suele requerir la colocación de un trocar de 10-12 mm o la ampliación de la incisión en la piel y fascia para extraer el tejido; esto implica desventajas estéticas y clínicas, como el riesgo de hernias incisionales. CASOS CLÍNICOS Se comunican tres casos de pacientes con diagnóstico de miomatosis de grandes elementos (7 cm el menor y 15 cm el mayor) en los que posterior a la miomectomía por laparoscopia se extrae la pieza quirúrgica íntegra mediante colpotomía posterior, con evolución posquirúrgica favorable y sin síntomas concomitantes. CONCLUSIÓN La extracción transvaginal mediante colpotomía posterior es una alternativa segura y efectiva para retirar piezas quirúrgicas porque la elasticidad de la vagina permite extraer de forma segura piezas grandes, y evitar así el uso del morcelador y sus posibles riesgos. Además, se evita ampliar las incisiones abdominales, lo que implica menor dolor posoperatorio, recuperación más rápida y mejores resultados cosméticos. La vía vaginal es segura, con mínimo riesgo de complicaciones y con mejores resultados posquirúrgicos comparada con el resto de las opciones de cirugía laparoscópica.

Abstract BACKGROUND The extraction of the myoma after laparoscopic resection can be done by: direct extraction, standard intra-abdominal morcellation, electric morcellation, extraction by posterior colpotomy or by minilaparotomy. Most of these options generally require placement of a 10-12 mm trocar and / or enlargement of the skin incision and fascia for tissue removal; In addition to the aesthetic disadvantages, it represents clinical implications such as the risk of incisional hernias. CLINICAL CASES We present 3 cases of patients with diagnosis of myomatosis of large elements, the smallest being 7 cm and the largest being 15 cm, in greater diameter, after the laparoscopic myomectomy the extraction of the complete surgical piece is performed through posterior colpotomy, presenting a favorable postoperative recovery, without associated symptoms. CONCLUSIONS The transvaginal extraction through posterior colpotomy represents a safe and effective alternative for the extraction of surgical pieces, the elasticity of the vagina allows the safe extraction of large pieces, avoiding the use of the morcellator and its possible risks; It also avoids expanding the abdominal incisions, associating to less postoperative pain, faster recovery and better cosmetic results. The vaginal route is a safe option with minimal risk of complications, and with better postsurgical results compared to the other options in laparoscopic surgery.

Leiomiomatosis benigna metastásica: reporte de caso clínico / Benign intraperitoneal metastatic leiomyomatosis: a case report

Benign intraperitoneal metastatic leiomyomatosis is a rare benign disease that is observed when a leiomyoma is present in the peritoneal surface. Women who have undergone hysterectomy for leiomyomas are most commonly affected. Patients are usually asymptomatic at presentation, being frequently an incidental finding in imaging studies. Ultrasound and CT play an important role in the diagnosis. The lesions are histologically identical to their uterine counterparts. There are different theories about the pathogenesis of the disease, including peritoneal seeding after laparoscopic hysterectomy. Others support the hypothesis of multiple independent foci of smooth muscle proliferation. Treatment, as in uterine leiomyomatosis, is generally conservative. We report a 53-year-old hysterectomized woman with intraperitoneal leiomyomas detected in a routine physical examination as mobile abdominal masses who underwent successful laparoscopic resection.

Severe postoperative dyspnea caused by neglected massive intraperitoneal fluid collection during laser enucleation and morcellation of the prostate: a case report / 대한마취과학회지

Laser enucleation and morcellation of the prostate is an increasingly used surgical management of benign prostatic hyperplasia. However, it can cause several complications including capsular perforation, ureteral orifice injury, and bladder mucosal morcellation injury. Herein, we report a case of severe postoperative dyspnea caused by neglected massive intraperitoneal fluid collection during laser surgery of the prostate. The patient experienced massive abdominal distension and severe respiratory difficulty after the procedure. Although immediate postoperative cystogram showed no leakage of contrast dye, the computed tomography scan of the abdomen and pelvis showed massive fluid collection in the abdominal pelvic cavity suggesting bladder wall injury. After percutaneous drainage of intraperitoneal fluid, abdominal distention and dyspnea were relieved.

Modified morcellation procedure in holmium laser enucleation of the prostate / 中华男科学杂志

<p><b>Objective</b>To evaluate the efficiency and safety of the modified versus conventional morcellation procedure in holmium laser enucleation of the prostate (HoLEP).</p><p><b>METHODS</b>We treated 195 patients with benign prostatic hyperplasia (BPH) by HoLEP, using conventional morcellation for 100 cases and modified morcellation for the other 95. We recorded the morcellation time, the total volume of resected tissue, the rate of morcellation, and associated complications, and compared the data obtained between the two groups.</p><p><b>RESULTS</b>The volumes of resected tissue were similar between the conventional and modified morcellation groups (［72.3±19.8］ vs ［71.1±17.7］ g, P>0.05). The morcellation time was significantly longer in the conventional than in the modified morcellation group (［12.8±2.8］ vs ［8.5±2.0］ min, P<0.01), and the morcellation rate was remarkably lower in the former than in the latter (［4.9±1.4］ vs ［7.1±0.9］ g/min, P<0.01). No statistically significant differences were observed in the incidence of complications, bladder injury for instance, between the two groups of patients.</p><p><b>CONCLUSIONS</b>The modified morcellation procedure can be used for mocellation of various types of tissue, with a higher efficiency than the conventional technique, and therefore deserves wide clinical application.</p>

A rare case of post-hysterectomy vault site iatrogenic endometriosis

A 45-year-old woman with a prior history of hysterectomy due to adenomyosis and leiomyomas was presented at our outpatient gynecology clinic 13 months later with sudden lower pelvic discomfort and vaginal bleeding symptoms. The patient underwent vaginal vault biopsy however diagnosis was still uncertain. Additional evaluation was required due to massive rebleeding incidents. After an emergent explorative laparoscopic operation with total excision of the vault, a diagnosis of vaginal vault endometriosis was made. Our theory is that a possible transplantation of endometrial cells during morcellation of the adenomyotic uterus which then may have progressed to iatrogenic endometriosis of the vaginal vault. Therefore, vault endometriosis must be considered in incidences of delayed massive bleeding occurring in post-hysterectomy patients when other diagnoses have been excluded.

Intrapelvic dissemination of early low-grade endometrioid stromal sarcoma due to electronic morcellation

Endometrioid stromal sarcoma is a rare malignancy that originates from mesenchymal cells. It is classified into low-grade endometrioid stromal sarcoma (LGESS) and high-grade endometrioid stromal sarcoma. Ultrasonographic findings of LGESS resemble those of submucosal myomas, leading to the possible preoperative misdiagnosis of LGESS as uterine leiomyoma. Electronic morcellation during laparoscopic surgery in women with LGESS can result in iatrogenic intraabdominal dissemination and a poorer prognosis. Here, we report a patient with LGESS who underwent a supracervical hysterectomy and electronic morcellation for a presumed myoma in another hospital. Disseminated metastatic lesions of LGESS in the posterior cul-de-sac and rectal serosal surface were absent on primary surgery, but found during reexploration. In conclusion, when LGESS is found incidentally following previous morcellation during laparoscopic surgery for presumed benign uterine disease, we highly recommend surgical reexploration, even when there is no evidence of a metastatic lesion in imaging studies.

Specimen processing during laparoscopic renal surgery: a review of techniques and technologies

Laparoscopic surgery has well-defined benefits for patients and has become accepted over time as a standard access strategy for the management of benign and malignant urologic diseases. Unlike in open surgery, the surgeon is often faced with the additional challenges of specimen retrieval and extraction at the end of laparoscopic extirpative procedures. This final step often requires significant laparoscopic skill to entrap and safely extract the laparoscopic specimens. Failure to apply safe exit steps at the end of a laparoscopic procedure may lead to significant morbidity. The aim of this review is to explore the different techniques and technologies available for laparoscopic kidney retrieval, entrapment and safe extraction. .

Technical Aspects of Holmium Laser Enucleation of the Prostate for Benign Prostatic Hyperplasia

Holmium laser enucleation of the prostate (HoLEP) is a minimally invasive procedure and a size-independent treatment for benign prostatic hyperplasia with excellent long-term surgical outcome. HoLEP has become an alternative to conventional transurethral resection of the prostate or open prostatectomy owing to its efficacy and safety. Although HoLEP is known to have a steep learning curve, very few articles have addressed the technical aspects of HoLEP. Herein, we described detailed techniques and tips for HoLEP as performed at Seoul National University Hospital in a step-by-step manner with extensive review of the literature.

Hallazgo de fragmentos uterinos intrabdominales poshisterectomía / Intraabdominal uterine fragments after laparoscopic hysterectomy

Se presentan los casos de tres pacientes en su quinta década de vida que fueron sometidas a histerectomia por miomas uterinos sintomáticos. Caso 1: Paciente sometida a histerectomia supracervical laparoscópica. El cuerpo uterino fue extraído del abdomen mediante morcelación eléctrica. Cuatro años después presenta intenso dolor pélvico cíclico que requiere hospitalizaciones. La resonancia magnética sugiere nodulos vascularizados en pelvis. Se efectúa laparotomía diagnóstica resecándose implantes de tejido miometrial y endometrio en pelvis. Caso 2: Paciente sometida a histerectomia subtotal laparoscopica hace 12 años por miomatosis uterina. Consulta por dolor en fosa iliaca izquierda con exacerbación cólica de larga evolución. La tomografia helicoidal sin contraste (pielo TAC) muestro imagen hipodensa en fosa iliaca izquierda. Se realiza laparoscopia quirúrgica resecándose el tumor. La biopsia fue informada como muestra constituida por pared tipo corporal uterino. Caso 3: Paciente sometida a histerectomia total abdominal. Dos años después en ecotomografía vaginal de rutina se pesquisa tumor pelviano sólido de probable origen anexial izquierdo. La resonancia magnética sugiere leiomioma. La laparoscopia diagnóstica objetiva tumor sólido en relación a la cúpula vaginal compatible con mioma. Se reseca el tumor y el estudio anátomo patológico confirma el diagnóstico. Conclusión: La retención de fragmentos uterinos es una complicación infrecuente de la histerectomia supracervical laparoscópica que sería posible prevenir. La laparoscopia tiene un rol en la resolución de retención de fragmentos uterinos post histerectomia. La resonancia magnética aportó información relevante en estos casos.

We will present the cases of three patients in the fifth decade of their life, that had undergone an histerec-tomy with the diagnosis of uterine leiomyoma. Case 1: Pacient had undergone a supracevical laparocopic hysterectomy. The uterus had been extracted from the abdominal cavity by electrical morcellation. Four years after the procedure, she presents ciclic pelvic pain which requires hospitalization. The magnetic resonante suggests vascularized tumors in the pelvis. A diagnostic laparoscopy was done, removing miometrial and endometrial tissue. Case 2: Pacient had undergone a supracevical laparocopic hysterectomy twelve years ago with the diagnosis of leiomyoma. She requires medical attention because of a colic pain in the left ilac fossa. The unhenhanced helicoidal CT- Scan shows an hipodense image in the left iliac fossa. A diagnostic laparoscopy was done, removing the tumor. The biopsy showed a sample constituded of uterine corpus. Case 3: Pacient had undergone an abdominal histerectomy. Two years after the procedure, a vaginal ecotomography showed a solid pelvian tumor that was propably located in the left adnexa. The magnetic resonante suggests a leyomioma. The diagnostic laparoscopy shows a solid tumor in touch with the cúpula vaginalis, the tumor was removed. The biopsy confirms the diagnosis. Conclusion: The uterine fragments retention is an infrecuent complication of the supracervical laparoscopic hysterectomy that can be prevenible. The laparoscopy has a role in the resolution of the uterine fragments post histerectomy. The magnetic resonance contributed with relevant information in this cases.
