ABSTRACT

Locally advanced tumor with involvement of surrounding tissues and organs is a common situation in pelvic malignancies. Up to 10% of newly diagnosed rectal cancer cases infiltrate to adjacent tissues and organs. Satisfactory resection margins obtained by pelvic exenteration can achieve a 5-year survival rate similar to cases that without adjacent tissue invasion. The 5-year survival rate of patients with locally recurrent pelvic malignancies is almost zero if they are treated only with radiotherapy and chemotherapy. To obtain negative margins through pelvic exenteration is the only chance for a long-term survival of these patients. However, pelvic exenteration is a complicated procedure with higher morbidity and mortality. The development of fascia anatomy enables surgeons to have a deeper understanding and comprehensive application of pelvic fasciae. Meanwhile, the improvement of laparoscopic technology provides a clearer view for surgeons and enables the application of minimally invasive techniques in complex pelvic exenteration. The fascial space priority approach is based on the fascia anatomy of pelvis and giving priority to the separation of the pelvic avascular fascial spaces, which provides a reproducible surgical approach for complex pelvic exenteration.

ABSTRACT

Objective: To investigate the value of reconstruction of pelvic floor with biological products to prevent and treat empty pelvic syndrome after pelvic exenteration (PE) for locally advanced or recurrent rectal cancer. Methods: This was a descriptive study of data of 56 patients with locally advanced or locally recurrent rectal cancer without or with limited extra-pelvic metastases who had undergone PE and pelvic floor reconstruction using basement membrane biologic products to separate the abdominal and pelvic cavities in the Department of Anorectal Surgery of the Second Affiliated Hospital of Naval Military Medical University from November 2021 to May 2022. The extent of surgery was divided into two categories: mainly inside the pelvis (41 patients) and including pelvic wall resection (15 patients). In all procedures, basement membrane biologic products were used to reconstruct the pelvic floor and separate the abdominal and pelvic cavities. The procedures included a transperitoneal approach, in which biologic products were used to cover the retroperitoneal defect and the pelvic entrance from the Treitz ligament to the sacral promontory and sutured to the lateral peritoneum, the peritoneal margin of the retained organs in the anterior pelvis, or the pubic arch and pubic symphysis; and a sacrococcygeal approach in which biologic products were used to reconstruct the defect in the pelvic muscle-sacral plane. Variables assessed included patients' baseline information (including sex, age, history of preoperative radiotherapy, recurrence or primary, and extra-pelvic metastases), surgery-related variables (including extent of organ resection, operative time, intraoperative bleeding, and tissue restoration), post-operative recovery (time to recovery of bowel function and time to recovery from empty pelvic syndrome), complications, and findings on follow-up. Postoperative complications were graded using the Clavien-Dindo classification. Results: The median age of the 41 patients whose surgery was mainly inside the pelvis was 57 (31-82) years. The patients comprised 25 men and 16 women. Of these 41 patients, 23 had locally advanced disease and 18 had locally recurrent disease; 32 had a history of chemotherapy/immunotherapy/targeted therapy and 24 of radiation therapy. Among these patients, the median operative time, median intraoperative bleeding, median time to recovery of bowel function, and median time to resolution of empty pelvic syndrome were 440 (240-1020) minutes, 650 (200-4000) ml, 3 (1-9) days, and 14 (5-105) days, respectively. As for postoperative complications, 37 patients had Clavien-Dindo < grade III and four had ≥ grade III complications. One patient died of multiple organ failure 7 days after surgery, two underwent second surgeries because of massive bleeding from their pelvic floor wounds, and one was successfully resuscitated from respiratory failure. In contrast, the median age of the 15 patients whose procedure included combined pelvic and pelvic wall resection was 61 (43-76) years, they comprised eight men and seven women, four had locally advanced disease and 11 had locally recurrent disease. All had a history of chemotherapy/ immunotherapy and 13 had a history of radiation therapy. The median operative time, median intraoperative bleeding, median time to recovery of bowel function, and median time to relief of empty pelvic syndrome were 600 (360-960) minutes, 1600 (400-4000) ml, 3 (2-7) days, and 68 (7-120) days, respectively, in this subgroup of patients. Twelve of these patients had Clavien-Dindo < grade III and three had ≥ grade III postoperative complications. Follow-up was until 31 October 2022 or death; the median follow-up time was 9 (5-12) months. One patient in this group died 3 months after surgery because of rapid tumor progression. The remaining 54 patients have survived to date and no local recurrences have been detected at the surgical site. Conclusion: The use of basement membrane biologic products for pelvic floor reconstruction and separation of the abdominal and pelvic cavities during PE for locally advanced or recurrent rectal cancer is safe, effective, and feasible. It improves the perioperative safety of PE and warrants more implementation.

ABSTRACT

Objective: To investigate the surgical indications and perioperative clinical outcomes of pelvic exenteration (PE) for locally advanced, recurrent pelvic malignancies and complex pelvic fistulas. Methods: This was a descriptive study.The indications for performing PE were: (1) locally advanced, recurrent pelvic malignancy or complex pelvic fistula diagnosed preoperatively by imaging and pathological examination of a biopsy; (2)preoperative agreement by a multi-disciplinary team that non-surgical and conventional surgical treatment had failed and PE was required; and (3) findings on intraoperative exploration confirming this conclusion.Contraindications to this surgical procedure comprised cardiac and respiratory dysfunction, poor nutritional status,and mental state too poor to tolerate the procedure.Clinical data of 141 patients who met the above criteria, had undergone PE in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2018 to September 2022, had complete perioperative clinical data, and had given written informed consent to the procedure were collected,and the operation,relevant perioperative variables, postoperative pathological findings (curative resection), and early postoperative complications were analyzed. Results: Of the 141 included patients, 43 (30.5%) had primary malignancies, 61 (43.3%) recurrent malignancies, 28 (19.9%) complex fistulas after radical resection of malignancies,and nine (6.4%)complex fistulas caused by benign disease. There were 79 cases (56.0%) of gastrointestinal tumors, 30 cases (21.3%) of reproductive tumors, 16 cases (11.3%) of urinary tumors, and 7 cases (5.0%) of other tumors such mesenchymal tissue tumors. Among the 104 patients with primary and recurrent malignancies, 15 patients with severe complications of pelvic perineum of advanced tumors were planned to undergo palliative PE surgery for symptom relief after preoperative assessment of multidisciplinary team; the other 89 patients were evaluated for radical PE surgery. All surgeries were successfully completed. Total PE was performed on 73 patients (51.8%),anterior PE on 22 (15.6%),and posterior PE in 46 (32.6%). The median operative time was 576 (453,679) minutes, median intraoperative blood loss 500 (200, 1 200) ml, and median hospital stay 17 (13.0,30.5)days.There were no intraoperative deaths. Of the 89 patients evaluated for radical PE surgery, the radical R0 resection was achieved in 64 (71.9%) of them, R1 resection in 23 (25.8%), and R2 resection in two (2.2%). One or more postoperative complications occurred in 85 cases (60.3%), 32 (22.7%)of which were Clavien-Dindo grade III and above.One patient (0.7%)died during the perioperative period. Conclusion: PE is a valid option for treating locally advanced or recurrent pelvic malignancies and complex pelvic fistulas.

ABSTRACT

Objective: To explore the feasibility, safety, and short- and long-term efficacy of laparoscopic pelvic exenteration (LPE) in treating locally advanced rectal cancer. Methods: The clinical data of 173 patients who had undergone pelvic exenteration (PE) for locally advanced rectal cancer that had been shown by preoperative imaging or intraoperative exploration to have invaded beyond the mesorectal excision plane and adjacent organs in the Cancer Hospital, Chinese Academy of Medical Sciences (n=64) and Peking University First Hospital (n=109) from 2010 January to 2021 December were collected retrospectively. Laparoscopic PE (LPE) had been performed on 82 of these patients and open PE (OPE) on 91. Short- and long-term outcomes (1-, 3-, and 5-year overall and disease-free survival and 1- and 3-year cumulative local recurrence rates) were compared between these groups. Results: The only statistically significant difference in baseline data between the two groups (P>0.05) was administration of neoadjuvant therapy. Compared with OPE, LPE had a significantly shorter operative time (319.3±129.3 minutes versus 417.3±155.0 minutes, t=4.531, P<0.001) and less intraoperative blood loss (175 [20-2000] ml vs. 500 [20-4500] ml, U=2206.500, P<0.001). The R0 resection rates were 98.8% and 94.5%, respectively (χ2=2.355, P=0.214). At 18.3% (15/82), and the incidence of perioperative complications was lower in the LPE group than in the OPE group (37.4% [34/91], χ2=7.727, P=0.005). The rates of surgical site infection were 7.3% (6/82) and 23.1% (21/91) in the LPE and OPE group, respectively (χ2=8.134, P=0.004). The rates of abdominal wound infection were 0 and 12.1% (11/91) (χ2=10.585, P=0.001), respectively, and of urinary tract infection 0 and 6.6% (6/91) (χ2=5.601, P=0.030), respectively. Postoperative hospital stay was shorter in the LPE than OPE group (12 [4-60] days vs. 15 [7-87] days, U=2498.000, P<0.001). The median follow-up time was 40 (2-88) months in the LPE group and 59 (1-130) months in the OPE group. The 1-, 3-, and 5-year overall survival rates were 91.3%, 76.0%, and 62.5%, respectively, in the LPE group, and 91.2%, 68.9%, and 57.6%, respectively, in the OPE group. The 1, 3, and 5-year disease-free survival rates were 82.8%, 64.9%, and 59.7%, respectively, in the LPE group and 76.9%, 57.8%, and 52.7%, respectively, in the OPE group. The 1- and 3-year cumulative local recurrence rates were 5.1% and 14.1%, respectively, in the LPE group and 8.0% and 15.1%, respectively, in the OPE group (both P>0.05). Conclusions: In locally advanced rectal cancer patients, LPE is associated with shorter operative time, less intraoperative blood loss, fewer perioperative complications, and shorter hospital stay compared with OPE. It is safe and feasible without compromising oncological effect.

ABSTRACT

With the development of existing surgical techniques, equipment and treatment concepts, more and more medical centers begin to carry out extensive resection for recurrent pelvic malignant tumors or those with multivisceral invasion. Exenteration may facilitate curative resection and improve the outcome of the patients. Therefore, pelvic exenteration has gradually become the standard of care for locally advanced pelvic malignancies. At present, pelvic exenteration leads to high intraoperative and postoperative complications and mortality, and therefore compromise the safety and long-term quality of life. Cumulating evidences suggest remnant cavity after exenteration might trigger the pathophysiological process and cause downstream complications which can be defined as empty pelvis syndrome. The literature related to empty pelvic syndrome was summarized, the possible cause of empty pelvic syndrome was analyzed. After the pelvic exenteration, the closed pelvic residual cavity formed continuous negative pressure with the gradual absorption of air in the cavity, bacterial propagation, and accumulation of fluid, which had an impact on the distribution of organs in the abdominal and pelvic cavity. At the same time, whether physical processes also play a role in the occurrence of empty pelvic syndrome remains to be explored. It is concluded that the diagnosis is mainly based on the patient's medical history, clinical manifestations and radiological findings, and the history of pelvic exenteration is the most important indicator in the diagnosis. In terms of prevention measures, we should identify the high-risk groups of the occurrence of empty pelvic syndrome, and then take accurate and individualized preventive measures. Various new biomaterials have more advantages in preventive pelvic cavity filling than traditional human tissue filling. Mesentery plays an important role in the morphology, peristalsis and arrangement of the small intestine. More attention should be paid to reducing the ectopic placement of the small intestine into the pelvic cavity by protecting the mesentery structure and restoring or rebuilding the mesentery morphology. In terms of treatment measures, there is still a lack of standard treatment pathway for empty pelvic syndrome.

ABSTRACT

Pelvic radiation injury can potentially involve multiple pelvic organs, and due to its progressive and irreversible nature, its late stage can be complicated by fistulas, perforations, obstructions and other complications involved multiple pelvic organs, which seriously affect the long-term survival and the quality of life of patients. As a multidisciplinary surgical approach, pelvic exenteration has potential application in the treatment of late complications of pelvic radiation injury by completely removing the irradiated lesion, relieving symptoms and avoiding recurrence of symptoms. In clinical practice, we should advocate the concept of "pelvic radiation injury", emphasize multidisciplinary collaboration, fully evaluate the overall status of patients, primary tumor and pelvic radiation injury. We should follow the principles of "damage-control" and "extended resection", and follow the principle of enhanced recovery after surgery to achieve the goal of ensuring the surgical safety, relieving patients' symptoms and improving patients' quality of life and long-term survival.

ABSTRACT

The treatment of locally advanced rectal cancer (LARC) or locally recurrent rectal cancer (LRRC) has been a difficulty and challenge in the field of advanced rectal cancer, while pelvic exenteration (PE), as an important way to potentially achieve radical treatment of LARC and LRRC, has been shown to significantly improve the long-term prognosis of patients. The implementation of PE surgery requires precise assessment of the extent of invasion of LARC or LRRC and adequate preoperative preparation through multidisciplinary consultation before surgery. The lateral pelvis involves numerous tissues, blood vessels, and nerves, and resection is most difficult, and the ureteral and Marcille triangle approaches are recommended; while the supine transabdominal approach combined with intraoperative change to the prone jacket position facilitates adequate exposure of the surgical field and enables precise overall resection of the bony pelvis and pelvic floor muscle groups invaded by the tumor. Empty pelvic syndrome has always been an major problem to be solved during PE. The application of extracellular matrix biological mesh to reconstruct pelvic floor defects and isolate the abdominopelvic cavity is expected to reduce postoperative pelvic floor related complications. Reconstruction of the urinary system and important vessels after PE is essential, and the selection of appropriate reconstruction methods helps to improve the patient's postoperative quality of life, while more new methods are also being continuously explored.

ABSTRACT

The China PelvEx Collaborative, under the direction of Colorectal Cancer Committee of the Chinese Medical Doctor Association, Gastrointestinal Surgery Committee of China International Exchange and Promotive Association for Medical and Health, has formulated and issued the Chinese expert consensus for primary rectal cancer beyond total mesorectal excision planes and locally recurrent rectal cancer (2023 edition) , with the academic support of the Chinese Journal of Gastrointestinal Surgery and Chinese Journal of Colorectal Disease (Electronic Edition). This Consensus refers to the expert consensus developed by the International PelvEx Collaboration, incorporates the latest international multi-center research results and combines the latest research results in China. The Consensus unifies some definitions, clarifies the surgical indications, and puts forward the definition and preventive measures of "empty pelvic syndrome" earlier. For the controversial classification of local recurrent rectal cancer, the Chinese classification was proposed for the first time in Consensus. At the same time, the definition of pelvic exenteration is controversial, and a more consistent cognition is proposed. It is believed that, with the in-depth research on complicated rectal cancer, C-PelvEx will gather more higher-level data from clinical research in several domestic centers, so as to further enrich the content of the updated Consensus.

ABSTRACT

In recent years, with advances in pelvic oncology and surgical techniques, surgeons have redefined the boundaries of pelvic surgery. Combined pelvic exenteration is now considered the treatment of choice for some patients with locally advanced and locally recurrent rectal cancer, but it is only performed in a few hospitals in China due to the complexity of the procedure and the large extent of resection, complications, and high perioperative mortality. Although there have been great advances in oncologic drugs and surgical techniques and equipment in recent years, there are still many controversies and challenges in the preoperative assessment of combined pelvic organ resection, neoadjuvant treatment selection and perioperative treatment strategies. Adequate understanding of the anatomical features of the pelvic organs, close collaboration of the clinical multidisciplinary team, objective assessment and standardized preoperative combination therapy creates the conditions for radical surgical resection of recurrent and complex locally advanced rectal cancer, while the need for rational and standardized R0 resection still has the potential to bring new hope to patients with locally advanced and recurrent rectal cancer.

ABSTRACT

Pelvic exenteration is often required for primary rectal cancer beyond total mesorectal excision (PRC-bTME) and locally recurrent rectal cancer (LRRC). Some patients with radical resection can achieve long-term survival, but they need to face risks, such as huge surgical trauma, serious perioperative complications, permanent loss of organ function and decline in quality of life. Preoperative evaluation of PRC-bTME and LRRC should emphasize multidisciplinary collaboration, and develop individualized diagnosis and treatment strategies. The principles of function preservation and risk-benefit balance in surgery oncology should be followed, and R0 resection should be emphasized. Perioperative complications, surgical trauma and organ function loss should be minimized to achieve the best quality control and balance point. This consensus was formulated by the Colorectal Cancer Committee of the Chinese Medical Doctor Association and the Gastrointestinal Surgery Committee of China International Exchange and Promotive Association for Medical and Health Care. The draft was formed based on the summary of domestic and foreign research progress and expert experience. After discussion, review and modification by experts, an anonymous voting was conducted for each major opinion, and in-depth verification was carried out according to the principles of evidence-based medicine. Finally, the Chinese expert consensus on the pelvic exenteration with primary rectal cancer beyond total mesorectal excision planes and locally recurrent rectal cancer (2023 edition) was formed. This consensus mainly summarizes the indications and contraindications of PE for PRC-bTME and LRRC, preoperative diagnosis and evaluation, perioperative treatment, as well as the resection scope, surgical methods, reconstruction of related organs, safety and complications of PE, postoperative follow-up and other issues, in order to provide guidance for PE in patients with PRC-bTME and LRRC.

ABSTRACT

Introducción. La evisceración intestinal transvaginal es consecuencia, en la gran mayoría de casos, de dehiscencia del muñón vaginal posterior a histerectomía en pacientes postmenopáusicas. A través de la dehiscencia vaginal se produce la salida del contenido abdominopélvico, que puede presentarse como una evisceración simple, incarceración, obstrucción, estrangulamiento y perforación de un asa intestinal. Caso clínico. Mujer de 78 años, con antecedente inmediato de colpocleisis y colporrafia con malla de polipropileno por prolapso vaginal, que presentó dehiscencia del muñón vaginal debido a rechazo de la malla, que condicionó la solución de continuidad de la pared vaginal, con prolapso, incarceración, obstrucción y perforación de íleon. Con el diagnóstico de evisceración intestinal transvaginal incarcerada con perforación intestinal se llevó a tratamiento quirúrgico, con abordaje inicial por vía vaginal para liberar el asa intestinal, luego por laparotomía se realizó resección y anastomosis de íleon, sacrocolpopexia con malla y plastia de Douglas. Presentó buena evolución postoperatoria.Conclusión. La evisceración intestinal transvaginal con perforación intestinal es una entidad de muy rara presentación. El órgano más frecuentemente comprometido es el intestino delgado, especialmente el íleon. Puede complicarse con incarceración, obstrucción intestinal, isquemia y perforación. El manejo quirúrgico involucra resección intestinal, cuando hay signos de necrosis, con reparación y fijación del muñón vaginal.


Introduction. Transvaginal intestinal evisceration is a consequence, in the vast majority of cases, of dehiscence of the vaginal stump after hysterectomy in postmenopausal patients. Through vaginal dehiscence, the exit of the abdominopelvic content occurs, which can present as a simple evisceration, incarceration, obstruction, strangulation and perforation of an intestinal loop. Clinical case. A 78-year-old woman with an immediate history of colpocleisis and polypropylene mesh colporrhaphy due to vaginal prolapse, presents dehiscence of the vaginal stump caused by rejection of the mesh that conditioned the solution of continuity of the vaginal wall, prolapse, incarceration, obstruction and perforation of the ileum. Surgical treatment was performed with the diagnosis of incarcerated transvaginal intestinal evisceration with intestinal perforation. The initial approach was to free the intestinal loop vaginally, followed by laparotomy, ileal resection and anastomosis, mesh sacrocolpopexy, and Douglas plasty were performed. He presented good postoperative evolution.Conclussion. Transvaginal intestinal evisceration with intestinal perforation is a very rare entity. The most common organ involved is the small intestine, especially the ileum. It can be complicated by incarceration, intestinal obstruction, ischemia, and perforation. Surgical management involves intestinal resection, when there are signs of necrosis, with repair and fixation of the vaginal stump.

ABSTRACT

RESUMEN Antecedentes: el uso de la proteína C reactiva (PCR) ha adquirido relevancia como identificador de complicaciones posoperatorias La morbilidad en cirugía colorrectal se estima en un 30% de los pacientes operados, lo que demanda medidas para su temprana identificación y terapéutica. Objetivo: describir las curvas de mediciones sucesivas de PCR y su relación con el desarrollo de complicaciones posoperatorias y niveles de glóbulos blancos en una serie de pacientes operados de cirugía colorrectal. Materiales y métodos: se realizó una revisión retrospectiva sobre un registro prospectivo de 2205 pacientes operados por la División de Cirugía Gastroenterológica del Hospital de Clínicas, entre enero de 2019 y julio de 2020. Se incluyeron 69 pacientes que cumplieron con los criterios de selección. Se consignaron datos del seguimiento clínico y dosaje de PCR, recuento de glóbulos blancos, vía de abordaje y desarrollo de complicaciones. Resultados: el promedio de edad fue de 59 años (DS 13,6; rango 33-85), 31 fueron hombres (43%). La tasa de complicaciones fue del 13,04%; más frecuente fue la fístula anastomótica (fístula, colección), seguida por complicaciones de la herida (hematoma, evisceración). Todos los pacientes mostraron un ascenso inicial del valor de PCR entre el 2° y 3er día, en relación con la lesión quirúrgica, los no complicados presentaron una cinética de descenso y los complicados. curvas de segundo ascenso o no descenso en las mediciones seriadas de PCR, y exhibían valores superiores de PCR cada día Se advirtieron diferencias estadísticamente significativas entre los valores de proteína C reactiva al 5° día posoperatorio en el subgrupo de pacientes complicados con respecto a aquellos con un curso indolente (28 mg/dL vs. 6,1 mg/dL, p < 0,001; IC: 11,24-39,61). hubo diferencia significativa al 5o día entre complicados y no complicados, independientemente de la vía de abordaje. con un valor de corte de PCR de 10,92 mg/dL obtuvimos una sensibilidad del 87,50% y una especificidad del 100% para excluir complicaciones. Conclusiones: la medición de la proteína C reactiva de forma seriada en los posoperatorios de cirugía colorrectal mostró un correlato con la identificación temprana de las complicaciones en nuestra serie, tanto en sus valores absolutos diarios como en la cinética de su comportamiento. se formula el uso de valores de corte para el alta segura.


ABSTRACT Background: The use of C-reactive protein (CRP) has gained relevance as a marker of marker of postoperative complications. As the incidence of complications of colorectal surgery is estimated to be of 30%, measures should for their early identification and treatment. Objective: To describe the performance of consecutive CRP determinations and their relationship with the development of postoperative complications and with white blood cell count in a series of patients undergoing colorectal surgery. Materials and methods: A retrospective review was performed using a prospective registry of 2205 patients operated on at the Department of Digestive Surgery of Hospital de Clínicas, between January 2019 and July 2020. A total of 69 patients fulfilling the selection criteria were included. Clinical follow-up data, CRP levels, white blood cell count, type of approach and development of complications were recorded. Results: Mean age was 59 years (SD 13.6; range 33-85) and 31 were men (43%). The complication rate was 13.04%. Anastomotic leak (fistula, fluid collection) was the most common complication, followed by surgical site complications (hematoma, evisceration). All patients showed an initial increase in CRP values between days 2 and 3, in relation with the surgical lesion, and then decreased in those without complications. Patients with complications had second rise or lack of decrease in serial CRP measurements, and higher CRP values each day. There were statistically significant differences between the CRP levels on postoperative day 5 in the subgroup of patients with complications compared with those with an indolent course (28 mg/dL vs. 6.1 mg/dL, p < 0.001; CI: 11.24-39.61). There was a significant difference on day 5 between patients with and without complications, irrespective of the approach. With a cut-off value of CRP of 10.92 mg/dL on postoperative day 5 we obtained a sensitivity of 87.50% and specificity of 100% to rule out complications. Conclusions: Serial determination of CRP in the postoperative period after colorectal surgery was associated with early identification of complications in our series, both in daily absolute values and in the kinetics of its performance. The use of cut-off values for safe discharge is proposed.

ABSTRACT

ABSTRACT Introduction: One of the most remarkable characteristics of urothelial carcinomas is multifocality. However, occurrence of synchronous bladder cancer and upper urinary tract urothelial cancer (UTUC) is exceptional. Minimally invasive approach for these synchronous tumors was just occasionally reported (1-4). The aim of this video article is to describe step-by-step the technique for simultaneous laparoscopic nephroureterectomy and robot-assisted anterior pelvic exenteration with intracorporeal ileal conduit urinary diversion (ICUD). Patients and methods: A 66-year-old female presented with synchronous BCG refractory non-muscle invasive bladder cancer and a right-side UTUC. She was a former smoker and had previously been submitted to multiple transurethral resections of bladder tumor, BCG and right distal ureterectomy with ureteral reimplant. We performed a simultaneous laparoscopic right nephroureterectomy and robot-assisted anterior pelvic exenteration with totally intracorporeal ICUD. Combination of robot-assisted and pure laparoscopic approaches was proposed focusing on optimization of total operative time (TOT). Results: Surgery was uneventful. TOT was of 330 minutes. Operative time for nephroureterectomy, anterior pelvic exenteration and ICUD were 48, 135, 87 minutes, respectively. Estimated blood loss was 150mL. Postoperative course was unremarkable and patient was discharged after 7 days. Histopathological evaluation showed a pT1 high grade urothelial carcinoma plus carcinoma in situ both in proximal right ureter and bladder, with negative margins. Twelve lymph nodes were excised, all of them negative. Conclusion: In our preliminary experience, totally minimally invasive simultaneous nephroureterectomy and cystectomy with intracorporeal ICUD is feasible. Pure laparoscopic approach to upper urinary tract may be a useful tactic to reduce total operative time.

ABSTRACT

ABSTRACT Pelvic exenteration has showed to be beneficial therapeutically and palliatively in locally advanced colorectal cancer. Reconstruction of urinary transit posterior to a cystectomy has always been challenging with many associated complications. We present a 58-year-old male with locally advanced rectal cancer in which a pelvic exenteration and a double-barreled wet colostomy (DBWC) was created for urinary reconstitution. We present the surgical technique of DBWC. DBWC is a good alternative to other urinary reconstructions because fecal and urinary derivation occurs in only one stoma, the stoma output is easier to manage, and fewer complications are seen compared to other urinary reconstructions. Long-term surveillance is mandatory in patients with a DBWC because there is an increased risk of neoplasm in the reservoir.


RESUMO A exenteração pélvica mostrou-se benéfica, tanto terapêutica quanto paliativamente, em casos de câncer colorretal localmente avançado. A reconstrução do trânsito urinário após uma cistectomia sempre foi desafiadora, com muitas complicações associadas. Os autores apresentam o caso de um homem de 58 anos de idade com câncer retal localmente avançado, submetido a uma exenteração pélvica e uma colostomia úmida em dupla-boca (CUDB) para reconstituição urinária. Os autores apresentam a técnica cirúrgica da CUDB, uma boa alternativa para outras reconstruções urinárias, já que a derivação fecal e urinária ocorre em apenas um estoma, a saída do estoma é mais fácil de gerenciar e o método apresenta menos complicações em comparação com outras reconstruções urinárias. A vigilância a longo prazo é obrigatória em pacientes com CUDB, pois há um risco aumentado de neoplasia no reservatório.

ABSTRACT

OBJECTIVE@#To investigate the value of neoadjuvant chemoradiotherapy (nCRT) combined with total pelvic exenteration (TPE) in the treatment of primary T4b rectal cancer.@*METHODS@#A retrospective cohort study was conducted to analyze the clinicopathological data of 31 patients with primary T4b rectal cancer who underwent TPE from January 2008 to December 2015 at Peking University First Hospital.@*INCLUSION CRITERIA@#preoperative clinical stage (cTNM) was defined as cT4b primary rectal cancer with only front wall Invasion; the lower edge of tumor was within 10 cm from the anal margin; TPE was performed; R0 resection was confirmed by pathology. Patients with recurrent rectal cancer, distant metastasis, and undergoing TPE for non-rectal tumors were excluded. Patients were divided into nCRT group and non-nCRT group according to whether receiving nCRT before surgery. The nCRT group received long course radiotherapy (total dose 50 Gy in 25 daily fractions) with concomitant chemotherapy (Capecitabine), and the surgery was performed 6-8 weeks after the neoadjuvant chemoradiation, while the non-nCRT group received surgery directly. The intraoperative, postoperative and pathological conditions and local recurrence were compared between the two groups. The survival curves were drawn by Kaplan-Meier method and the survival of two groups were compared.@*RESULTS@#A total of 31 patients were enrolled, including 13 patients in the nCRT group and 18 patients in the non-nCRT group. The baseline data, such as age, duration of disease, preoperative basic disease, body mass index, smoking rate, and tumor distance from the anal margin, were not significantly different between the two groups (all P>0.05). In the nCRT group and non-nCRT group respectively, the ratio of anal preservation was 30.8%(4/13) and 38.9%(7/18) (P=0.468), the median intraoperative blood loss was 1 000 ml and 800 ml (P=0.644), the operation time was (531.7±137.2) minutes and (498.0±90.1) minutes (P=0.703), the median hospital stay was 18 days and 14 days (P=0.400), the morbidity of complications within 30 days after surgery was 23.1%(3/13) and 38.9%(7/18)(P=0.452), the incidence of postoperative abdominal abscess was 15.4%(2/13) and 0 (P=0.168), the proportion of secondary surgery was 7.7%(1/13) and 11.1%(2/18)(P=1.000), whose differences were not significantly different. The proportion of postoperative pathological pT4b in whole group was 58.1%(18/31), including 53.8%(7/13) in nCRT group and 61.1%(11/18) in non-nCRT group, which was not significantly different between the two groups (P=0.691). The number of harvested lymph node in nCRT group was 13.5±5.9, which was significantly less than 23.0±11.8 in non-nCRT group (P=0.013). There was no pathological complete remission (ypCR) case in nCRT group, and among 13 patients, tumor regression grade (TRG) of 2, 3, 4, and 5 was in 1 case (7.7%), 6 cases (46.2%), 5 cases(38.5%), and 1 case (7.7%), respectively. The median follow-up time was 33 (2 to 115) months, and the follow-up rate was 93.5%(29/31). One case was lost in both the nCRT group and non-nCRT group. The 3-year disease-free survival rate was 43.5% in pooled data, and was 43.6% and 43.3% in nCRT group and non-CRT group respectively without significant difference (P=0.833). The 3-year overall survival rate was 51.1% in pooled data, and was 45.7% and 54.7% in nCRT group and non-nCRT group respectively without significant difference (P=0.653).The local recurrence rate of nCRT and non-nCRT groups was 8.3%(1/12) and 5.9%(1/17) respectively, and the distant metastasis rate was 50.0%(6/12) and 41.2%(7/17) respectively, whose differences were not statistically significant as well (P=1.000 and P=0.865, respectively).@*CONCLUSION@#For primary T4b rectal cancer which can achieve R0 resection through total pelvic exenteration, neoadjuvant chemoradiotherapy has not been demonstrated any advantage in tumor regression, reducing local recurrence, or improving survival, and may increase postoperative complications.

ABSTRACT

<p><b>Background</b>Pelvic exenteration (PE) for primary and recurrent cervical cancer has resulted in favorable survival outcomes, but there are controversies about specific prognosis factors, and up to now, there have been no published reports from China. This study aimed to share our experiences of PE, which were performed in a single institution.</p><p><b>Methods</b>From January 2009 to January 2016, 38 patients with recurrent or persistent cervical cancer were included in the study, and they were followed up until January 2017. Epidemiological and clinicopathological characteristics of patients were compared for survival outcomes in univariate and Cox hazard regression analysis.</p><p><b>Results</b>There were thirty-one and seven patients with recurrent and persistent cervical cancer, respectively. The median age of patients was 45 years (range 29-65 years). Total, anterior, and posterior PE consisted of 52.6%, 28.9%, and 18.4% of cases, respectively. Early and late complications occurred in 21 (55.3%) patients and 15 (39.5%) patients, respectively. Two (5.3%) patients died due to complications related to surgeries within 3 months after PE. The median overall survival (OS) and disease-free survival (DFS) were 28.5 months (range 9-96 months) and 23 months (range 4-96 months), respectively, and 5-year OS and DFS were 48% and 40%, respectively. Cox hazard regression analysis showed that, the margin status of the incision and mesorectal lymph node status were independent risk factors for OS and DFS.</p><p><b>Conclusion</b>In our patients with recurrent and persistent cervical cancer, the practice of PE might achieve favorable survival outcomes.</p><p><b>Trial Registration</b>ClinicalTrials.gov, NCT03291275; https://clinicaltrials.gov/ct2/show/NCT03291275?term=NCT03291275&rank=1.</p>

ABSTRACT

OBJECTIVE: To determine the effect of surgeon experience on intraoperative, postoperative and long-term outcomes among patients undergoing pelvic exenteration for gynecologic cancer. METHODS: This was a retrospective analysis of all women who underwent exenteration for a gynecologic malignancy at MD Anderson Cancer Center, between January 1993 and June 2013. A logistic regression was used to model the relationship between surgeon experience (measured as the number of exenteration cases performed by the surgeon prior to a given exenteration) and operative outcomes and postoperative complications. Cox proportional hazards regression was used to model survival outcomes. RESULTS: A total of 167 exenterations were performed by 19 surgeons for cervix (78, 46.7%), vaginal (43, 25.8%), uterine (24, 14.4%), vulvar (14, 8.4%) and other cancer (8, 4.7%). The most common procedure was total pelvic exenteration (69.4%), incontinent urinary diversion (63.5%) and vertical rectus abdominis musculocutaneous reconstruction (42.5%). Surgical experience was associated with decreased estimated blood loss (p < 0.001), intraoperative transfusion (p = 0.009) and a shorter length of stay (p = 0.03). No difference was noted in the postoperative complication rate (p = 0.12–0.95). More surgeon experience was not associated with overall or disease specific survival: OS (hazard ratio [HR] = 1.02; 95% confidence interval [CI] = 0.97–1.06; p = 0.46) and DSS (HR = 1.01; 95% CI = 0.97–1.04; p = 0.66), respectively. CONCLUSION: Patients undergoing exenteration by more experienced surgeons had improvement in intraoperative factors such as estimated blood loss, transfusion rates and length of stay. No difference was seen in postoperative complication rates, overall or disease specific survival.

ABSTRACT

Objetivo: El objetivo de este estudio es mostrar los resultados inmediatos y alejados de la exenteración pélvica total (EPT) en el manejo de tumores primarios de recto localmente avanzados. Se describe una alternativa técnica en los casos de EPT supraelevador. La EPT puede ser la única oportunidad de curación en pacientes con tumores pélvicos de gran volumen. Material y método: Se incluyen tumores T4 por la estadificación clínica o los hallazgos operatorios sometidos a una EPT con intención curativa. Resultados: En un periodo de 16 años se intervienen con esta técnica 10 pacientes, 6 de los cuales recibieron radioquimioterapia neoadyuvante. La técnica clásica se empleó en 3 pacientes y la EPT supraelevador, en 6. El promedio de hospitalización fue de 36 días (rango, 18-97) y la morbilidad alcanzó el 80%. El estudio de la pieza operatoria confirmó un tumor T4 en 6 pacientes, T3 en 3 y T0 en uno. Los 6 pacientes con neoadyuvancia son 1 ypT0N0M0, 2 ypIIA, 2 ypIIC y 1 ypIIIB. El resto eran 2 pIIC y 2 pIIIC. En el seguimiento hay 5 pacientes vivos entre 30 y 180 meses, y 3 fallecen por metástasis a distancia sin recidiva local. Conclusión: La EPT es una intervención asociada a una elevada morbilidad y larga estadía hospitalaria. La EPT supraelevador protegida mediante una ileostomía transitoria evitó una colostomía definitiva en 6 de 10 casos. La ileostomía urinaria muestra resultados funcionales satisfactorios en el largo plazo. La sobrevida prolongada en la mitad de los pacientes justifica la indicación de la técnica en casos seleccionados.


Aim: To report the results of total pelvic exenteration (TPE) in patients with locally advanced primary rectal tumors. Material and method: We report 10 patients with stage 4 rectal tumors subjected to a potentially curative TPE in a period of 16 years. Results: Six patients received also adjuvant chemoradiotherapy. A classic technique was used in 3 patients and a supra-elevator technique in 6. Mean hospitalization length was 36 days, and 80% of patients had complications. The pathological study of the surgical piece confirmed a T4 tumor in 6 patients, T3 in 3 and T0 in one. Among patients who received chemoradiotherapy, one was in stage ypT0N0M0, 2 in ypIIA, 2 in ypIIC, one in ypIIIB, 2 in pIIC and 2 in pIIIC. During follow up 3 patients survived between 30 and 180 months and three died due to distant metastases without local relapse. Conclusion: TPE requires long hospital stays and has a high rate of complications. Supra-elevator TPE protected with a transitory ileostomy avoided definitive colostomy in 6 of 10 cases. Urinary ileostomy had satisfactory long term functional results. The prolonged survival of half of the patients justifies the use of this surgical technique.
