OBJECTIVE
The incidence of recurrent hernia after radical resection of prostate cancer is high, so this article discusses the incidence and risk factors of inguinal hernia after radical resection of prostate cancer.
METHODS
This case control study was conducted in The First People's Hospital of Huzhou clinical data of 251 cases underwent radical resection of prostate cancer in this hospital from March 2019 to May 2021 were retrospectively analyzed. According to the occurrence of inguinal hernia, the subjects were divided into study group and control group, and the clinical data of each group were statistically analyzed, Multivariate Logistic analysis was performed to find independent influencing factors for predicting the occurrence of inguinal hernia. The Kaplan-Meier survival curve was drawn according to the occurrence and time of inguinal hernia.
RESULTS
The overall incidence of inguinal hernia after prostate cancer surgery was 14.7% (37/251), and the mean time was 8.58 ± 4.12 months. The average time of inguinal hernia in patients who received lymph node dissection was 7.61 ± 4.05 (month), and that in patients who did not receive lymph node dissection was 9.16 ± 4.15 (month), and there was no significant difference between them (P > 0.05). There were no statistically significant differences in the incidence of inguinal hernia with age, BMI, hypertension, diabetes, PSA, previous abdominal operations and operative approach (P > 0.05), but there were statistically significant differences with surgical method and pelvic lymph node dissection (P < 0.05). The incidence of pelvic lymph node dissection in the inguinal hernia group was 24.3% (14/57), which was significantly higher than that in the control group 11.8% (23/194). Logistic regression analysis showed that pelvic lymph node dissection was a risk factor for inguinal hernia after prostate cancer surgery (OR = 0.413, 95%Cl: 0.196-0.869, P = 0.02). Kaplan-Meier survival curve showed that the rate of inguinal hernia in the group receiving pelvic lymph node dissection was significantly higher than that in the control group (P < 0.05).
CONCLUSION
Pelvic lymph node dissection is a risk factor for inguinal hernia after radical resection of prostate cancer.

INTRODUCTION
Over the last decade there has been a transition from traditional laparoscopy to robotic surgery for the treatment of endometrial cancer. A number of gynecological oncology surgical fellowship programmes have adopted robot-assisted laparoscopy, but the effect of training on complications and survival has not been evaluated. Our aim was to assess the impact of a proficiency-based progression training curriculum in robot-assisted laparoscopy on peri-operative and survival outcomes for endometrial cancer.
METHODS
This is an observational cohort study performed in a tertiary referral and subspecialty training center. Women with primary endometrial cancer treated with robot-assisted laparoscopic surgery between 2015 and 2022 were included. Surgery would normally include a hysterectomy and salpingo-oophorectomy with some form of pelvic lymph node dissection (sentinel lymph nodes or lymphadenectomy). Training was provided according to a training curriculum which involves step-wise progression of the trainee based on proficiency to perform a certain surgical technique. Training cases were identified pre-operatively by consultant surgeons based on clinical factors. Case complexity matched the experience of the trainee. Main outcome measures were intra- and post-operative complications, blood transfusions, readmissions < 30 days, return to theater rates and 5-year disease-free and disease-specific survival for training versus non-training cases. Mann-Witney U, Pearson's chi-squared, multivariable regression, Kaplan-Meier and Cox proportional hazard analyses were performed to assess the effect of proficiency-based progression training on peri-operative and survival outcomes.
RESULTS
Training cases had a lower BMI than non-training cases (30 versus 32 kg/m, = 0.013), but were comparable in age, performance status and comorbidities. Training had no influence on intra- and post-operative complications, blood transfusions, readmissions < 30 days, return to theater rates and median 5-year disease-free and disease-specific survival. Operating time was longer in training cases (161 versus 137 min, = < 0.001). The range of estimated blood loss was smaller in training cases. Conversion rates, critical care unit-admissions and lymphoedema rates were comparable.
DISCUSSION
Proficiency-based progression training can be used safely to teach robot-assisted laparoscopic surgery for women with endometrial cancer. Prospective trails are needed to further investigate the influence of distinct parts of robot-assisted laparoscopic surgery performed by a trainee on endometrial cancer outcomes.

Giant mucinous cystadenocarcinoma of the ovary is rarely described. Huge ovarian masses are mostly benign, but malignancy should be ruled out by investigations and clinical assessment. Here, we present a case of a large mucinous cystadenocarcinoma of the ovary in a 48-year-old postmenopausal woman. Imaging examinations revealed a large cystic tumor that filled the whole abdominal cavity. Despite the difficulties presented by the size of the tumor and its malignant potential, laparotomy was carried out, which included bilateral salpingo-oophorectomy, total abdominal hysterectomy, exploration of other intra-abdominal organs, and pelvic lymphadenectomy. Histopathology indicated the presence of mucinous cystadenocarcinomas. Adjuvant chemotherapy was given post-operatively, and the patient maintained remission during follow-up. This case emphasizes the need for early detection by simple imaging modalities such as ultrasonography in cases of ovarian masses. Most adnexal masses, if detected early, are amenable to surgical management with a good prognosis. Large masses underline the need for a multidisciplinary approach to improve patient outcomes.

INTRODUCTION
Cervical cancer management often relies on surgical interventions, among which open total mesometrial resection (TMMR) has gained prominence. This abstract gives an insight into the technique of TMMR in the surgical treatment of cervical cancer. TMMR involves precise dissection of the mesometrium surrounding the cervix, aiming for optimal oncological outcomes while minimizing surgical morbidity.
METHODS OR TECHNIQUE
TMMR entails meticulous dissection of the mesometrium surrounding the cervix, following embryonic planes to ensure complete removal of the primary tumour and associated lymphadenectomy. Access to the abdomen is achieved through either a muscle-cutting transverse or midline abdominal incision. The procedure emphasizes meticulous dissection and removal of the tumour-containing area, with careful attention to preserving vital structures such as the ureters and pelvic autonomic nerves to minimize postoperative complications. Extensive lymphadenectomy, including first and second echelon nodal groups, and in selected cases, third echelon nodes such as lower paraaortic nodes, is performed.
CONCLUSION
TMMR offers several advantages, including precise identification and preservation of vital structures, thorough lymphadenectomy, and favourable oncological outcomes with improved survival rates. Importantly, TMMR allows for the avoidance of radiation therapy in the majority of operable cervical cancer cases. In conclusion, TMMR represents a cornerstone in the surgical management of cervical cancer, striking a balance between oncological efficacy, radiation avoidance, and preservation of patients' quality of life.

OBJECTIVE
To assess the feasibility, safety, and efficiency of simultaneous anterograde video laparoscopic inguinal and pelvic lymphadenectomy for penile cancer.
MATERIALS AND METHODS
We reviewed retrospectively the records of 22 patients (44 lateral) who underwent inguinal lymph nodes dissection for penile cancer. The procedure was standardized as two planes, three holes, and six steps. Two Separate-planes: superior plane of eternal oblique aponeurosis/ / fascia lata; inferior plane of superficial camper fascia. Three holes: two artificial lateral boundary holes, the internal and external boundary holes, and the hole of oval fossa. Six steps: separate the first separate-plane; separate the second layer; separate two artificial lateral boundary holes; free great saphenous vein; separate the third hole and clean up the deep inguinal lymph nodes; pelvic lymphadenectomy.
RESULTS
A total of 22 cases were included and 9 patients underwent simultaneous pelvic lymphadenectomy. The average operation time on both sides was 7.52 ± 3.29 h, which was 0.5-1 h/side after skilled. The average amount of bleeding was 93.18 ± 50.84 ml. A total of 8 patients had postoperative complications, accounting for 36.36%, and no complications great than Clavien-Dindo class III occurred.
CONCLUSION
This study demonstrated that the video laparoscopic simultaneous anterograde inguinal and pelvic lymphadenectomy is a feasible and safe technique. Indocyanine Green was helpful for lymph node identify.

Review
In rectal cancer treatment, the diagnosis and management of lateral pelvic lymph nodes (LLN) are critical for preventing local recurrence. Over time, scholars have reached a consensus: when imaging suggests LLN metastasis, combining neoadjuvant chemoradiotherapy (nCRT) with selective LLN dissection (LLND) can mitigate the risk of recurrence. Selective LLND typically encompasses lymph nodes in the internal iliac and obturator regions. Recent studies emphasize distinctions between internal iliac and obturator lymph nodes regarding prognosis and treatment outcomes, prompting the need for differentiated diagnostic and treatment approaches.

OBJECTIVE
This study aimed to determine whether the number of resected pelvic lymph nodes (PLNs) affects the prognosis of endometrial cancer (EC) patients at post-operative risk of recurrence.
METHODS
JGOG2043 was a randomized controlled trial to assess the efficacy of three chemotherapeutic regimens as adjuvant therapy in EC patients with post-operative recurrent risk. A retrospective analysis was conducted on 250 patients who underwent pelvic lymphadenectomy alone in JGOG2043. The number of resected and positive nodes and other clinicopathologic risk factors for survival were retrieved.
RESULTS
There were 83 patients in the group with less than 20 PLNs removed (group A), while 167 patients had 20 or more PLNs removed (group B). There was no significant difference in patients' backgrounds between the two groups, and the rate of lymph node metastasis was not significantly different. There was a trend toward fewer pelvic recurrences in group B compared with group A (3.5% vs. 9.6%; p=0.050). Although Kaplan-Meier analysis showed no statistically significant difference in survival rates between the two groups (5-year overall survival [OS]=90.3% vs. 84.3%; p=0.199), multivariate analysis revealed that resection of 20 or more nodes is one of the independent prognostic factors (hazard ratio=0.49; 95% confidence interval=0.24-0.99; p=0.048), as well as surgical stage, high-risk histology, and advanced age for OS.
CONCLUSION
Resection of 20 or more PLNs was associated with improved pelvic control and better survival outcomes in EC patients at risk of recurrence who underwent pelvic lymphadenectomy alone and were treated with adjuvant chemotherapy.

INTRODUCTION AND IMPORTANCE
With the widespread use of positron emission tomography and computed tomography (PET/CT), a significantly greater proportion of patients with advanced ovarian cancer (OC) are now diagnosed with superior renal-vein lymph node metastases involving retrocrural and mediastinal nodes. To the authors' knowledge, retrocrural lymphadenectomy has not yet been reported in patients with OC. The authors performed retrocrural lymph node resection in a patient with ovarian cancer.
CASE PRESENTATION
A 64-year-old woman with ovarian cancer who had not undergone surgery upon initial diagnosis was admitted to the authors' hospital because tumour markers increased during bevacizumab maintenance therapy. PETCT imaging revealed adnexal masses and multiple metastases in pelvic, paraaortic, retrocrural, and mediastinal lymph nodes. Reduction surgery was performed, and retrocrural lymph nodes were excised. However, the patient's postoperative course was complicated by a chylothorax. Because of the failure of conservative treatment, interventional embolization was performed, but failed to obstruct lymphatic vessels. The patient underwent reoperation. A fistula was located where Hem-o-lock clips penetrated the pleura, clearly indicating the injury site, which was then sutured and embedded in the surrounding diaphragmatic tissue and filled with gel sponge. The patient recovered from chylous leakage postoperatively. She later underwent chemotherapy and targeted maintenance therapy.
CLINICAL DISCUSSION
The authors may have injured the communicating branch of the thoracic duct posterior to the diaphragm during the first operation and did not ligate it. The accumulated chylous fluid finally penetrated through the weak point on the pleura and led to chylothorax 3 days later. If conservative treatment or interventional embolization are unsuccessful, surgical treatment should be selected in time.
CONCLUSION
The location of the retrocrural lymph node at the anastomosis of the chylous cistern and the thoracic duct may pose a significant risk of chylous leakage as a complication of lymphadenectomy. Full exposure of the surgical field and thorough ligation of the lymphatic vessels may lead to successful superior renal-vein lymphadenectomy.

Technique modifications that aim to improve ergonomics of the surgical procedure without repositioning the upper tract urothelial carcinoma patients remain a challenge to urologists. We offer a novel technique to perform intraperitoneal laparoscopic single-site radical nephroureterectomy and pelvic lymph nodes dissection/retroperitoneal lymph nodes dissection in a supine position. Our novel technique is feasible and offers a significant improvement in operative efficiency, particularly in patients with locally advanced disease.

Colorectal cancer ranks among the most commonly diagnosed cancers globally, and is associated with a high rate of pelvic recurrence after surgery. In efforts to mitigate recurrence, pelvic lymph node dissection (PLND) is commonly advocated as an adjunct to radical surgery. Neoadjuvant chemoradiotherapy (NACRT) is a therapeutic approach employed in managing locally advanced rectal cancer, and has been found to increase the survival rates. Chua have proposed a combination of NACRT with selective PLND for addressing lateral pelvic lymph node metastases in rectal cancer patients, with the aim of reducing recurrence and improving survival outcomes. Nevertheless, certain studies have indicated that the addition of PLND to NACRT and total mesorectal excision did not yield a significant reduction in local recurrence rates or improvement in survival. Consequently, meticulous patient selection and perioperative chemotherapy may prove indispensable in ensuring the efficacy of PLND.
