Impact of age on central lymph nodes involvement in papillary thyroid cancer.

BACKGROUND: Total thyroidectomy is the main line of treatment for papillary thyroid cancer. Central lymph node dissection (CLND) is still debatable. In this study, we aimed to correlate the central lymph node status with the age of patients. METHODS: This is a retrospective study including patients with papillary thyroid cancer (PTC) who underwent total thyroidectomy and CLND at a tertiary cancer center during the period from January 2012 to September 2022. Patients were subdivided into 3groups: patients younger than 20 years old, patients between 20 and 40 years old, and patients older than 40 years old. Correlation between central lymph node status, lateral lymph node status, and harvest count with each other and between age groups was done. RESULTS: 315 patients were included. The younger the age group the higher the possibility of harboring positive central nodes, however, the positivity of lateral nodes was similar. Neither central nodal harvest nor positive central node count significantly differed between groups. The lateral nodal harvest was significantly higher in the < 20 years group with no affection to the number of positive nodes retrieved. The younger the age group the longer the disease-free survival (DFS). CONCLUSION: We can conclude that patients younger than twenty years had a higher probability of harboring malignancy in central nodes and higher lateral node harvest on dissection. In contrast, they do have a lower incidence of recurrence.

Multicenter validation of the PREDICT score for prediction of local recurrence after total mesorectal excision of rectal cancer.

BACKGROUND: Total mesorectal excision (TME) is the gold standard treatment for rectal cancer. Although TME has managed to decrease the rates of local recurrence after rectal cancer resection, local recurrence is still recorded at varying rates. The present study aimed to validate the PREDICT score in the prediction of local recurrence of rectal cancer after TME with curative intent. METHODS: This was a retrospective multicenter study on patients with nonmetastatic low or middle rectal cancer who underwent TME. The total PREDICT score was calculated for every patient and related to the onset of local recurrence. According to the final score, patients were allocated to one of three risk groups: low, moderate, and high, and the rates of local recurrence in each group were calculated and compared. RESULTS: The present study included 262 patients (50.4% males) with a mean age of 47.1 years. The overall local recurrence rate was 12.6%. 29.4% of patients were in the low-risk group, 63.7% in the moderate-risk group, and 6.9% in the high-risk group. The local recurrence rate was 3.9% (95% confidence interval [CI]: 0.8-10.9) in the low-risk group, 13.2% (95% CI: 8.4-19.3) in the moderate risk group, and 44.4% (95% CI: 21.5-69.2) in the high-risk group (p < 0.0001). The sensitivity of the PREDICT score was 72.7%, the specificity was 88.1%, and the accuracy was 86.3%. CONCLUSIONS: The PREDICT score had good diagnostic accuracy in the prediction of local recurrence after TME and a good discriminatory ability in the differentiation between patients at different risks to develop local recurrence.

Reconstruction of Oromandibular Defect After Tumor Resection by Sternomastoid-clavicular Flap.

ABSTRACT: The study aims to evaluate sternocleidomastoid-clavicular osteo-myocutaneous flap (SCM-OMCF) for reconstruction of mandibular defects after tumor resection. In the period between 2010 and 2018, thirteen patients with primary mandibular tumors underwent mandibular resection and reconstruction with SCM-OMCF. Patients were followed up for 10 to 66 months. Hospital was 13 ±â€Š4 days. All patients started fluid in the 2nd day. The mean time to start oral fluid was 7.5 ±â€Š0.8 day. Four (30.8%) patients suffered from complications (infection and salivary leak in 1 case due to partial flap loss, donor wound dehiscence in 1 case, deep venous thrombosis in 1 case and chest infection in 1 case). None of our cases experienced motor disability. Two cases (15.9%) underwent reoperations. The overall aesthetic outcome was found excellent in 5 cases, satisfactory in 5 cases and fair in 3 cases. The functional outcomes were satisfactory. Tumor recurrences were detected in 2 (15.9%) patients. Two patients died during follow up within 2 years after 1st surgery due to local and distant recurrences. SCM-OMCF is a versatile, safe and simple technique for reconstructing mandibular defects less than 11 cm.

Preoperative localization of sentinel lymph node in breast cancer patients by silver wire insertion or liquid charcoal injection guided by CT lymphography.

Dual localization of SLN in breast cancer patients using isotope & dye is the best-approved modality with limitations such as high cost of radioactive materials, complex logistic preparations & scheduling issues, especially in developing countries. We investigated the feasibility & accuracy of a novel technique for SLN localization using silver wire insertion or liquid charcoal injection guided by CT lymphography. 120 patients with clinically node-negative breast cancer were enrolled. In the test group, SLN was localized using preoperative CTLG guided injection of liquid charcoal or by placing a 3 cm silver wire. In addition, intraoperative SLN mapping was performed using methylene blue dye followed by searching for the SLN localized by both methods. In the control group, SLN was localized by the blue dye only. Feasibility, accuracy, detection rates, and number of SLNs retrieved were reported as well as matching between the LN detected with the CTLG and that detected with the dye technique. SLN could be detected in 59 out of 60 patients (98.3%) in the test group and in 54 out of 60 patients (90%) in the control group (P = .057). In self-controlled analysis of the test group comparing CTLG only to dye only was significant (P = .050). Comparing charcoal to silver wire in detection was statistically insignificant (P = .5). This novel method can offer advantages which are as follows: being more accurate than the dye alone, saving operative time, abandoning complex logistic preparations for the radioisotope, and solving the problem of timing.

Multicentric adrenocorticotropic hormone -producing steroid cell tumor of the fallopian tube & broad ligament in a 15 year old girl.

Steroid cell tumors occur usually in the ovaries with very few reported cases of extra-ovarian origin. Our patient was a fifteen year old female, complaining from secondary amenorrhea and voice deepening. Values of serum cortisol, DHEA, FSH & LH were normal. Serum Testosterone was elevated while ACTH-pm was markedly elevated. MRI described bilateral solid para-ovarian masses. Exploration revealed two bilateral tubal extraluminal cysts & a right broad ligament cyst which were all excised. Pathological examination led to the diagnosis of steroid cell tumor. Serum testosterone & ACTH returned to normal levels after surgery with subsequent regression of the virilizing symptoms. We can conclude that extra-ovarian steroid cell tumors are extremely rare. They are usually presented with virilizing symptoms and hormonal abnormalities. Surgery is the main line of treatment.

Role of P53, E-cadherin and BRAF as predictors of regional nodal recurrence for papillary thyroid cancer.

BACKGROUND: Regional nodal recurrence (RNR) in patients diagnosed with papillary thyroid carcinoma (PTC) has increased. Variable immunohistochemical (IHC) markers have been studied for predicting the likelihood of PTC for recurrence. We aimed to clarify the IHC expression of p53, Ecadherin and BRAF as potential markers of RNR in PTC. METHOD: 145 (73 study group and 72 control group) patients with PTC were analyzed retrospectively between January 2010 and June 2017. Further classification to a specific histological variant was done, and IHC expression of p53, Ecadherin and BRAF was analyzed both in the primary tumor and in nodal recurrence. RESULTS: Regarding the risk of RNR, we found certain clinicopathologic features as elder age ≥55 years, tumor size >1 cm, presence of microscopic extrathyroid extension, presence of lymphovascular emboli, and conventional papillary subtype. Furthermore, IHC results for negative E-cadherin, and positive P53 and BRAF are significant risk factors, while radioactive iodine (RAI) adjuvant therapy decrease recurrence risk. CONCLUSION: We found several risk factors for RNR in PTC diagnosed patients, all of which are easily achievable in clinical settings. In this regard, we suggested that patients with specific clinicopathologic and immunohistochemical features have strict follow up for early detection of RNR as it has a great impact on their survival.

Complications and adverse events in lymphadenectomy of the inguinal area: worldwide expert consensus.

BACKGROUND: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes. The aim of this study was to devise a system to standardize the classification and reporting of inguinal lymph node dissection perioperative complications by creating a worldwide collaborative, the complications and adverse events in lymphadenectomy of the inguinal area (CALI) group. METHODS: A modified 3-round Delphi consensus approach surveyed a worldwide group of experts in inguinal lymph node dissection for melanoma, penile and vulval cancer. The group of experts included general surgeons, urologists and oncologists (gynaecological and surgical). The survey assessed expert agreement on inguinal lymph node dissection perioperative complications. Panel interrater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS: Forty-seven experienced consultants were enrolled: 26 (55.3%) urologists, 11 (23.4%) surgical oncologists, 6 (12.8%) general surgeons and 4 (8.5%) gynaecology oncologists. Based on their expertise, 31 (66%), 10 (21.3%) and 22 (46.8%) of the participants treat penile cancer, vulval cancer and melanoma using inguinal lymph node dissection respectively; 89.4% (42 of 47) agreed with the definitions and inclusion as part of the inguinal lymph node dissection intraoperative complication group, while 93.6% (44 of 47) agreed that postoperative complications should be subclassified into five macrocategories. Unanimous agreement (100%, 37 of 37) was achieved with the final standardized classification system for reporting inguinal lymph node dissection complications in melanoma, vulval cancer and penile cancer. CONCLUSION: The complications and adverse events in lymphadenectomy of the inguinal area classification system has been developed as a tool to standardize the assessment and reporting of complications during inguinal lymph node dissection for the treatment of melanoma, vulval and penile cancer.

Effect of non-invasive follicular thyroid neoplasm with papillary-like features (NIFTP) terminology on surgical management concepts.

BACKGROUND: Despite the strict diagnostic criteria recently proposed for non-invasive follicular thyroid neoplasm with papillary-like features (NIFTP), its incidence is still unknown. Employing a retrospective analysis of the follicular variant of papillary thyroid carcinoma (FVPTC), we investigated the diagnosis, prevalence and postoperative course of NIFTP. METHODS: We examined retrospectively the records of 112 patients who had undergone thyroid surgery and had a postoperative diagnosis of FVPTC at our hospital from 2010 to 2021. All clinical, radiologic, and pathologic features were evaluated. RESULTS: Only 34 (27.9%) patients met the strict pathologic criteria for NIFTP; 11 cases having been diagnosed as NIFTP initially and 23 after re-evaluation of histopathologic slides. None of the 11 NIFTP patients underwent a 2-stage operation, in contrast to 10 (29.4%) patients initially diagnosed as FVPTC who had a completion thyroidectomy after the initial hemithyroidectomy. The median follow-up was 14.5 (ranging from 0 to 78) months. None of the cases developed a recurrence. CONCLUSION: To avoid unnecessary treatment or the follow-up advised for papillary thyroid carcinoma, clinicians and pathologists should be familiar with the terminology and the corresponding diagnostic criteria for NIFTP and their impact on management.

Fungating and Ulcerating Breast Cancer: Wound Closure Algorithm, Complications, and Survival Trends.

Fungating breast cancer severely affects patients' daily lives, and patient management poses major oncology challenges. To present 10-year outcomes of unique tumor presentation, suggesting a focused algorithm for surgical management and providing deep analysis for factors affecting survival and surgical outcomes. Eighty-two patients with fungating breast cancer were enrolled in the period from January 2010 to February 2020 in the Mansoura University Oncology Center database. Epidemiological and pathological characteristics, risk factors, different surgical treatment techniques, and surgical and oncological outcomes were reviewed. Preoperative systemic therapy was used in 41 patients, with the majority (77.8%) showing progressive response. Mastectomy was performed in 81 (98.8%) patients, with primary wound closure in 71 (86.6%), and wide local excision in a single patient (1.2%). Different reconstructive techniques in non-primary closure operations were used. Complications were reported in 33 (40.7%) patients, of which 16 (48.5%) were of Clavien-Dindo grade II category. Loco-regional recurrence occurred in 20.7% of patients. The mortality rate during follow-up was 31.7% (n = 26). Estimated mean overall survival (with 95% CI) was 55.96 (41.98-69.9) months; estimated mean loco-regional recurrence-free survival (with 95% CI) was 38.01 (24.6-51.4) months. Surgery is a cornerstone fungating breast cancer treatment option, but at the expense of high morbidity. Sophisticated reconstructive procedures may be indicated for wound closure. A suggested algorithm based on the center's experience of wound management in difficult mastectomy cases is displayed.

The epidemiological and clinicopathological characteristics of multifocal/multicentric breast cancer in the Egyptian Delta and its impact on management strategies.

BACKGROUND: Multifocal (MFBC)/multicentric (MCBC) breast cancer is being more recognized due to the improved imaging modalities and the greater orientation with this form of breast cancer, however, optimal surgical treatment, still poses a challenge. The standard surgical treatment is mastectomy, however, breast-conserving surgeries (BCS) may be appropriate in certain situations. METHODS: A total of 464 cases of MF/MCBC out of 4798 cases of breast cancer were retrospectively analyzed from the database of the Oncology Center, Mansoura University (OCMU), between January 2008 and December 2019. RESULTS: Radiologic involvement of multiple quadrants was reported in 27.9% by ultrasonography, 19% by mammography, and 59.1% by magnetic resonance imaging. BCS was performed in 32 cases (6.9%) while 432 cases underwent a mastectomy. Postoperative pathology revealed infiltration of other quadrants grossly in 23.5%, and under the microscope in 63.6% of the examined cases. Mean disease-free and overall survival were 95.5 and 164.6 months, respectively. When compared with MFBC, MCBC showed higher pathologic tumor size (p < 0.001), higher stages (p < 0.001), higher recurrence rates (p = 0.006), and lower DFS (P = 0.009) but with similar OS (P = 0.8). CONCLUSION: Mastectomy is still the primary treatment option for MCBC with higher recurrence rates compared with MFBC. However, BCS for properly selected MFBC is considered oncologically safe, following the same rules of breast conservation for unifocal disease.

Is it essential to remove the submandibular gland in neck dissection in tongue cancer patients?

INTRODUCTION: Submandibular sialadenectomy is a part of the classic technique of neck dissection for oral cavity cancers. However, its removal is associated with a reduction in the salivary outflow in many patients, as well as, some uncommon complications such as lingual and hypoglossal nerve injuries. Assessment of the necessity of such maneuvers should be addressed. PATIENTS AND METHODS: The data of 105 patients with tongue cancer who underwent neck dissection in the Oncology Center, Mansoura University from January 2008 to March 2019 were reviewed and analyzed retrospectively. RESULTS: In all the included patients, whether showing pathologic positive or negative lymph nodes, none showed capsular or parenchymal submandibular gland metastasis except for one patient who showed direct infiltration of the gland by the primary tumor. CONCLUSION: Submandibular sialadenectomy may not be indicated as a part of neck dissection in tongue cancer patients. Further research should be conducted to focus on the effect of its preservation on disease-free and overall survival.

The Impact of Narrow and Infiltrated Distal Margin After Proctectomy for Rectal Cancer on Patients' Outcomes: a Systematic Review and Meta-analysis.

Rectal cancer is a common tumor within a difficult anatomic constraint. Total mesorectal excision with longitudinal and circumferential free margins is considered imperative for good prognosis. In this article, the authors systematically reviewed all published literature with specific Mesh terms until the end of year 2019. Thereafter, retrieved articles were assessed using the Newcastle-Ottawa Scale and meta-analysis was conducted comparing local recurrence among 1-cm, 5-mm, and narrow (< 1-mm)/infiltrated margins. Thirty-nine articles were included in the study. Macroscopic distal margin < 1 cm carried a higher incidence of recurrence for those who did not receive neoadjuvant radiation, without affecting neither estimated overall nor disease-free survival. Less than 5-mm margin after radiation therapy is accepted oncologically. Infiltrated margins and narrow margins (< 1 mm) microscopically are associated with higher incidence of local recurrence and shorter overall and disease-free survival. Surgeons should aim at 1-cm safety margin in radiotherapy-naïve patients and microscopic free margin > 1 mm for those who received neoadjuvant therapy. The cost/benefit of reoperation for patients with infiltrated margins is still inadequately studied.

Impact of Morbid Obesity on the Outcomes of Type II Endometrial Cancer: a Cohort Study.

Obesity has long been associated with endometrial cancer. However, there is a paucity of studies addressing the impact of morbid obesity in type II endometrial cancer on oncologic and surgical outcomes. In this study, the author retrospectively compared morbid to non-morbid obese in clinico-epidemiologic, surgical, and oncologic outcomes. Both groups were comparable as regards all clinico-epidemiologic parameters. Vaginal involvement, survival, and recurrence were also comparable between the 2 groups. Para-aortic adenopathy and treatment with preoperative therapy were the only significant predictors of DFS. Surgery is feasible with equivalent complications and oncologic outcomes in morbidly obese patients with type II endometrial cancer.

Prognostic value of androgen receptor expression in different molecular types of breast cancer in women.

BACKGROUND: Breast cancer is a common women's disease. Usually, oestrogen is blamed in the aetiology and correlated with the prognosis; however, androgens are recently raising concern about its role in the breast cancer treatment and prognosis. METHODS: In this study we retrieved archival paraffin blocks of breast cancer patients and stained it for androgen. Thereafter, we compared clinico-epidemiologic parameters, histopathology, neoadjuvant response and recurrence rate and pattern among patients with and without androgen receptor (AR) expression. RESULTS: In total, 119 patients fulfilled enrolment criteria; AR expression were present in 77.3% of the patients. AR expression was associated with less grade III (6.8% versus 36.4%), and less triple negative (6.2% versus 25%), but similar overall recurrence rate (25% versus 22.2%). However, distant recurrence was significantly higher in androgen positive patients (91.3% versus 33.3% of all recurrences). CONCLUSION: Androgen expression appears to be common among breast cancer, but with no clear implication in tumour aggressiveness or effect on the rate of recurrence. However, being commonly associated with distant spread may have an impact on survival of the patients.

Fibroadenoma of the breast; incidence of malignancy and indicators for surgical intervention: An analysis of 1392 patients.

BACKGROUND: Fibroadenomas are common among young females. The size of the lesion used to be an indication for further assessment or excision. With arising of the watch and see proponents, criteria for selecting patients are important to establish. METHODS: This is a retrospective study of a prospectively maintained database where all patients having the clinical/radiological provisional diagnosis of fibroadenoma and attending our center - from January 2008 to March 2020 - were enrolled. The primary outcome was the incidence of malignancy and the secondary outcomes were the correlation of malignancy-risk with epidemiologic and radiologic criteria. RESULTS: The study enrolled 1392 patients. The mean age of the patients was 35.7 + ∕- 13.1 years. The median of the longest diameter of the detected breast lesions was 25 mm. The incidence of malignancy was 188 (13.5%). The size of the lesion measured by largest diameter was insignificant (p = 0.99), while the patients' age, marital status, and imaging criteria as measured by BIRADS score were significant (<0.001). CONCLUSION: Approaching patients with the age above 35 or with BIRADS 4 provisionally diagnosed with fibroadenomas should be cautious with biopsy and short-term follow-ups The size of the tumor alone should not be used as an indication for surgical intervention.

Operative Feasibility and Short-Term Oncologic Outcome of Rigid Versus Flexible Platforms in Transanal Total Mesorectal Excision.

Several transanal platforms were used to perform transanal total mesorectal excision (TaTME). They can be classified into rigid reusable platforms or flexible single-use platforms. The choice of transanal platform usually depends on the availability and the surgeon's discretion. To the best of our knowledge, this is the first study to compare the operative and oncologic outcome of flexible and rigid platforms during TaTME. This is a retrospective cohort study in which rectal cancer patients operated by TaTME in two tertiary centers from June 2013 to April 2019 were included. They were classified into two groups according to the platform used either the rigid platform group (n = 17) or the flexible platform (n = 14). Operative feasibility and short-term oncologic data were analyzed and reported. A total number of 31 patients were divided into either the rigid platform group (n = 17) versus the flexible platform one (n = 14). Shorter operating time, less blood loss, better TME specimens, and lymph node yield were reported in the flexible platform group. Flexible platforms were associated with better operative outcomes. Although there were no differences in circumferential and distal margins between the two groups, better TME specimens' quality and lymph node yield were reported in the flexible platform group. Future prospective trials are encouraged to provide better evidence.

Electro-thermal bipolar vessel sealing versus clipping of the inferior mesenteric vessels during minimally invasive proctectomy.

INTRODUCTION: The introduction of new energy vessel sealing devices in minimally invasive proctectomy led to better hemostatic effect, less blood loss, and shorter operating time. At present, the available evidence from literature about the use of electro-thermal bipolar vessel sealers (EBVS) in laparoscopic rectal cancer surgery is weak where most studies are retrospective with non-homogenous patient groups. METHODS: This is a retrospective cohort study where 40 rectal cancer patients operated by laparoscopic TME or laparoscopic assisted transanal total mesorectal excision were classified in two groups according to approach of inferior mesenteric vessels ligation (EBVS versus Clipping). RESULTS: The operative time was significantly longer and the blood loss was significantly more in the EBVS group. However, hospital stay, time to oral, time to starting stoma function, and number of retrieved lymph nodes were not significantly affected by the method of vascular control. CONCLUSION: Both methods for control of vascular pedicle during minimally invasive rectal cancer surgery are safe, as such it is at the discretion of the operating surgeon to which method to use. Prospective well-designed trials are awaited to provide stronger evidence.

ANTECEDENTES: La introducción de nuevos dispositivos de sellado de vasos energéticos en la proctectomía mínimamente invasiva condujo a un mejor efecto hemostático, una menor pérdida de sangre y un tiempo de operación más corto. Actualmente, la evidencia disponible en la literatura sobre el uso de EBVS (electro-thermal bipolar vessel sealers) en cirugía laparoscópica de cáncer rectal es débil, pues la mayoría de los estudios son retrospectivos con grupos de pacientes no homogéneos. MÉTODO: Estudio de cohorte retrospectivo con 40 pacientes con cáncer rectal operados por escisión mesorrectal total laparoscópica o asistida por laparoscopia, clasificados en dos grupos según el enfoque de la ligadura de los vasos mesentéricos inferiores (EBVS vs. recorte). RESULTADOS: El tiempo operatorio fue significativamente mayor y la pérdida de sangre fue significativamente mayor en el grupo EBVS. Sin embargo, el método de control vascular no afectó significativamente el tiempo de hospitalización, el tiempo hasta el inicio de la función del estoma ni el número de ganglios linfáticos recuperados. CONCLUSIÓN: Ambos métodos para el control del pedículo vascular durante la cirugía de cáncer rectal mínimamente invasiva son seguros, por lo que queda a discreción del cirujano el método a utilizar. Se esperan ensayos prospectivos bien diseñados para proporcionar pruebas más sólidas.

Transanal Versus Laparoscopic Total Mesorectal Excision: A Comparative Prospective Clinical Trial from Two Centers.

Purpose: Laparoscopic total mesorectal excision (LapTME) faced many obstacles in obese male with narrow pelvis and bulky mesorectum with increased risk of incomplete mesorectal excision and positive circumferential resection margin (CRM) and distal resection margin (DRM). Transanal total mesorectal excision (TaTME) is reported to result in a better quality total mesorectal excision (TME) specimen, lower incidence of CRM and DRM involvement, and higher rates of sphincter preservation. To date, there is still a debate about the feasibility and efficacy of transanal versus the laparoscopic approach for TME in middle and low rectal cancer. Materials and Methods: This is a prospective controlled clinical trial where 38 patients of middle or low rectal cancer from two tertiary centers were nonrandomly assigned to either TaTME or LapTME. Results: Eighteen patients were operated by TaTME versus 20 patients by LapTME. Mean body mass index was significantly higher in the TaTME group (30.74 ± 7.79) than in the LapTME group (25.99 ± 4.68) (P = .03). TaTME was associated with more transanal specimen extraction (55.5% versus 20%, P = .06). No significant differences were detected in CRM, DRM, peri- or postoperative complications, or conversion rates with more reported Clavien-Dindo grade III complications in the TaTME group (P = .29). Conclusions: TaTME facilitated rectal cancer surgery in obese patients and increased the chance of transanal specimen extraction with equivalent oncological outcomes to conventional LapTME. Further studies are recommended to build better evidence.

Significance of Omental Infiltration in Gastric Cancer Patients: a Retrospective Cohort Study.

BACKGROUND: Stomach cancer is a curative disease in early stages. The optimal extent and approach for gastric resection are still evolving. PATIENTS AND METHODS: In this study, we examined the value, as well as, the predictors of omental disease spread, retrospectively, in a group of patients with gastric cancer who attended the Oncology Center, Mansoura University, in the period between January 2006 and April 2017. RESULTS: Nodal metastasis, especially heavy disease (N2 and beyond), and advanced stage are predictors of the presence of omental disease. However, neither overall nor disease-free survival is affected by omental infiltration. CONCLUSION: Omental resection will continue being an integral part of gastric resection, but the level of omental cutting needs further studies.

Short-Term Surgical Outcomes of Standard and Lateral Video Endoscopic Inguinal Lymphadenectomy: A Multinational Retrospective Study.

Background: Video endoscopic inguinal lymphadenectomy (VEIL) is a minimally invasive technique that gives superior surgical outcomes than open inguinal lymphadenectomy (IL) for treating lymph node metastasis in penile, vulvar, and skin cancers. This study compared surgical outcomes obtained with two different approaches of VEIL, standard VEIL and lateral VEIL (L-VEIL), in cancer patients. Methods: Sixty-two patients who underwent standard VEIL (n = 15) or L-VEIL (n = 47) for treatment of lymph node metastasis were evaluated retrospectively from three centers in Brazil, Egypt, and India. Primary endpoint analyzed was conversion rate to open IL in the two groups, and the secondary endpoints included operative time, estimated blood loss, nodal yield, nodal positivity, postoperative drain duration, and postoperative complications. Results: The conversion rate to open IL was higher in L-VEIL compared with VEIL group (2% vs. 0%). Significantly lesser blood loss was reported with L-VEIL compared with VEIL (mean difference: 3.63 mL; P = .01). Postoperative drain duration was significantly lower with L-VEIL (-4.34 days; P < .05) than VEIL. The L-VEIL group had a higher number of lymph nodes without infiltration (mean difference: -0.48; P = .02). Operative time, nodal yield, nodal positivity, and hospitalization duration were similar in both groups. Postoperative complications were higher in the L-VEIL versus VEIL group (35 vs. 11 cases). Lymphedema events were significantly higher with L-VEIL in comparison with VEIL (38.8% vs. 16.7%; P = .03). Among patients with penile cancer, no significant difference was observed in outcomes obtained with VEIL and L-VEIL. Conclusion: As L-VEIL and VEIL approaches lead to comparable surgical outcomes, surgeons may choose either of these as per their convenience.
