Robot-Assisted Video Endoscopic Inguinal Lymph Node Dissection for Penile Cancer: An Indian Multicenter Experience.

Objective: To report outcomes of multicenter series of penile cancer patients undergoing robot-assisted video endoscopic inguinal lymph node dissection (RA-VEIL). Materials and Methods: In this retrospective analysis from 3 tertiary care centers in India, consecutive intermediate-/high-risk carcinoma penis (CaP) patients with nonpalpable inguinal lymphadenopathy and/or nonbulky (<3 cm) mobile inguinal lymphadenopathy undergoing RA-VEIL were included. Patients with matted/bulky (>3 cm) and fixed lymphadenopathy were excluded. Demographic, clinical, and intraoperative data were recorded. Perioperative complications were graded by the Clavien-Dindo classification (CDC). The International Society of Lymphology (ISL) {0-III} grading was used for the assessment of lymphedema. Incidence and pattern of recurrences were assessed on follow-up. Results: From January 1, 2011, to September 30, 2023, 115 patients (230 groins) underwent bilateral RA-VEIL for CaP. The median age of the cohort was 60 (50-69) years. Clinically palpable (either unilateral or bilateral) inguinal lymphadenopathy was seen in 54 patients (47%). The "per groin" median operative time was 120 (100-140) minutes with median lymph node yield of 12 (9-16). No complications were recorded in 87.8% groins operated, with major complications (CDC 3) seen in 2.6% groins. At a median follow-up of 13.5 months, 13 patients had documented recurrences and there were 10 cancer-related deaths. No port-site recurrences were observed. No/minimal lymphedema (ISL 0/I) was seen in 94% legs. Conclusion: RA-VEIL demonstrates safety and oncologic efficacy in penile cancer patients presenting with clinically nonpalpable and/or nonbulky inguinal lymphadenopathy, with favorable functional outcomes.

A retrospective analysis of the factors associated with increased risk of readmission within 30 days after primary transurethral resection of bladder tumor.

Background: Transurethral resection of bladder tumor (TURBT) is associated with perioperative morbidity of 5% to 10%, which can lead to unplanned readmissions. In this study, we aimed to identify the factors that lead to an increased risk of unplanned readmissions within 30 days of primary TURBT. Materials and methods: A retrospective study was conducted to identify patients who underwent primary TURBT at our institute from 2011 to 2019. Clinical and demographic factors, history of smoking, antiplatelet drugs intake, comorbidities, tumor size (<3 or >3 cm), multifocality, and histopathological type were abstracted. Patients who were readmitted were identified, and reasons for admission were recorded. Results: A total of 435 patients were identified. The median age of the patients was 66 years. From 378 male patients (86.9%), 110 (25.3%) and 37 (8.5%) had a history of smoking and antiplatelet agents intake, respectively. In the cohort, 166 patients (38.2%) were diabetic, 239 (54.9%) were hypertensive, 72 (16.6%) had chronic obstructive pulmonary disease, and 78 (7.9%) had hypothyroidism. A total of 206 patients (47.4%) had a tumor >3 cm; multifocality was seen in 140 (32.2%) patients, whereas muscle invasive tumors were present in 161 patients (37%). A total of 22 patients (5.06%) had readmissions within 30 days, with hematuria being the most common etiology. On univariate and multivariate analyses, a history of smoking (p = 0.006 and p = 0.008, respectively) or antiplatelet agents intake (p < 0.001 and p < 0.001, respectively) was significantly associated with increased unplanned readmission. Conclusions: Our study revealed smoking and antiplatelet agents intake as factors leading to an increased risk of unplanned readmissions.

Para-aortic nodal metastasis of mesenteric perivascular epithelioid cell tumor (PEComa).

Perivascular epithelioid cell tumors (PEComas) are a group of tumours of mesenchymal origin having a characteristic pathological presence of the epitheloid cell around blood vessels. They are uncommon tumours and hence their exact etiology and pathogenesis remain unclear. They can occur at any part of the body but the common sites of involvement are the gastrointestinal system and the genitourinary system. The isolated involvement of the intestinal mesentery is very rare, with only a few cases reported in the literature till date. The involvement of lymph nodes by these tumours is exceptionally rare. We report a hitherto undescribed case of mesenteric PEComa in a young female who developed para-aortic nodal metastasis.

The clinical conundrum of a catecholamine secreting giant adrenal myelolipoma.

Adrenal myelolipomas are uncommon tumours of unknown aetiology. They arise from the adrenal cortex and comprise lipomatous and myeloid elements. They are considered to be functionally inert, and metabolic evaluation is not mandatory for them. Adrenal myelolipomas can rarely be functionally active, and patients may present with hypertension, electrolyte imbalance or features of Cushing's syndrome. The association of these tumours with catecholamine secretion is exceptionally rare. We describe a case of a functional adrenal myelolipoma associated with catecholamine secretion in a 55-year-old female patient with a history of hypertension. The surgical excision of the mass resulted in normalisation of the urinary catecholamine levels and resolution of the hypertension.

The use of preoperative neutrophil-lymphocyte ratio and lymphocyte-monocyte ratio in predicting survival and groin node involvement of patients with squamous cell carcinoma of penis.

INTRODUCTION: The association between inflammation and malignancies is being recognized. In this study, we assessed the use of preoperative neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR) in predicting cancer-specific survival (CSS) and inguinal node involvement in patients with carcinoma penis. METHODS: Sixty-nine patients operated for squamous cell carcinoma penis with inguinal node dissection between 2012 and 2020 were identified. We recorded the type of surgery (partial/total penectomy), T stage, grade, lymphovascular invasion (LVI), perineural invasion (PNI), pathological status of inguinal nodes and nodal stage (pN1-3), extranodal extension (ENE), and CSS. The hemogram performed within 2 weeks of surgery was used for calculating NLR and LMR. RESULTS: Partial penectomy was the most common surgery (65.22%) and pT2 was the most common stage (53.62%). Grade 2 was seen in 66.67%, LVI in 34.78%, PNI in 37.68%, 52.17% had inguinal node involvement with pN3 being the most common (36.23%), and 36.23% had ENE. Kaplan-Meier analysis revealed that NLR of >3 and the LMR ≤3 indicated an inferior CSS (P = 0.05 and 0.04, respectively). T stage, inguinal node involvement, LVI, pN stage, and ENE were also associated with inferior CSS (P < 0.05). On multivariate analysis, T stage was significantly associated with CSS (P = 0.02). The NLR >3 and LMR ≤3 were also significantly associated with the presence of pathological inguinal node involvement (P = 0.001 and 0.026). CONCLUSION: NLR and LMR may help in predicting CSS and inguinal node involvement in patients of carcinoma penis.

Simplifying Laparoscopic Nephrectomy for Beginners: Double Window Technique With En Bloc Hilar Stapling.

Laparoscopic nephrectomy is a commonly performed procedure. As with any surgical procedure, this too has a significant learning curve. The management of renal hilum is the most critical part of this surgery. It requires a meticulous intra-hilar dissection to identify the renal artery and vein. The kidneys are extremely vascular structures and any injury to these vessels during dissection can result in life-threatening bleeding. Hence, it is obvious that beginners most often face difficulty and apprehension at this step of the laparoscopic nephrectomy. We describe a simple technique of laparoscopic nephrectomy which includes the creation of two windows, one at the lower pole and the second at the upper pole, isolation of the hilum, and en bloc stapling of the renal hilar vessels. This method safeguards against collateral damage to the surrounding structures. It also avoids the need for intra-hilar dissection, hence decreasing the chances of vascular injuries.

Laparoscopic management of isolated metachronous adrenal metastases in a patient with esophageal cancer: a case report.

BACKGROUND: The presence of isolated metachronous adrenal metastasis in patients with esophageal cancer is rare. There is significant controversy regarding the management of such patients. Adrenal metastasectomy has been shown to be of benefit in some reports. Minimally invasive approach, although the gold standard for adrenalectomy, has not been used commonly in a postesophagectomy setting owing to the anticipated technical difficulties. We describe one such case wherein this approach helped in early recovery and long-term survival. CASE PRESENTATION: A 59-year-old male of Asian ethnicity presented with an isolated left adrenal nodule, 3 years after an Ivor Lewis esophagectomy for a lower esophageal adenocarcinoma. The biopsy of the nodule was suggestive of metastatic adenocarcinoma. The patient underwent laparoscopic excision of the left adrenal gland. CONCLUSION: Adrenal metastasectomy, in postesophagectomy patients can provide good oncological control. Laparoscopic approach, though technically challenging, can provide results equivalent to those of open surgery, albeit with less morbidity.

Unusual presentation of castrate-resistant prostate cancer with urethral and inguinal nodal metastasis.

Metastatic involvement of the urethra is a rare finding in patients with carcinoma prostate. The signs and symptoms overlap with those of a primary urethral malignancy. The diagnosis is made following a biopsy of the suspected lesions. We describe the case of a 66-year-old patient with carcinoma prostate who presented with penile pain, 18 months after the treatment with androgen deprivation therapy. Ga-68 prostate-specific membrane antigen positron emission tomography/computed tomography helped in the identification of the urethral and inguinal nodal metastasis, which was confirmed histologically. We also discuss the management of this unusual clinical scenario.

Laparoscopic and robotic video endoscopic inguinal lymphadenectomy by the lateral approach.

INTRODUCTION: Video endoscopic inguinal lymphadenectomy (VEIL) improves on open inguinal node dissection because it offers decreased morbidity. In conventional VEIL, port placement is along the long axis of the femur, above the knee joint. In the laparoscopic approach, this placement is fraught with problems because the camera hits the knee, the surgeon must reach over the camera, and sword fighting occurs between the instruments. In the robotic approach, external collisions are likewise not uncommon because of a lack of optimal spacing between the robot's arms. Here, we describe our lateral approach technique that can be used for both laparoscopic and robotic platforms and can help solve the problems presented by conventional VEIL. METHODS: A retrospective review was performed to examine the records of all patients who had undergone VEIL at our institution for management of squamous cell carcinoma of the penis. Patients who had undergone lateral VEIL were identified. The clinical factors, surgery details, time to discharge and drain removal, postoperative complications, and nodal pathology were recorded. RESULTS: A total of 30 VEILs-26 laparoscopic and 4 robotic-were performed by the lateral approach. On clinical examination, none of the patients had clinically palpable nodes. The mean operative time on one side was 100 minutes (range, 80-140 minutes). The blood loss was minimal in all cases, and there were no conversions to open procedures. The mean time to drain removal was 7 days (range, 5-12 days). Two patients developed bilateral lymphoceles. CONCLUSIONS: Lateral VEIL is feasible and can be used as an alternative to conventional VEIL.

Pulmonary lymphangitis carcinomatosa in a patient with carcinoma of urinary bladder.

Pulmonary lymphangitis carcinomatosa occurs due to dissemination of cancer cells in pulmonary lymphatics. It is only rarely seen with urological malignancies and portends a grave prognosis. Its presence in patients with urothelial carcinoma of the urinary bladder is uncommon. We present a case of a nested variant of transitional cell carcinoma of the urinary bladder associated with pulmonary lymphangitis carcinomatosa. We also discuss the symptoms and radiological features that might aid in timely diagnosis of this entity.

Society of Onco-Anesthesia and Perioperative Care (SOAPC) advisory regarding perioperative management of onco-surgeries during COVID-19 pandemic.

Coronavirus disease 2019 (COVID-19) has gripped the world and is evolving day by day with deaths every hour. Being immunocompromised, cancer patients are more susceptible to contract the infection. Onco-surgeries on such immunocompromised patients have an increased risk of infection of COVID-19 to patients and health care workers. The society of Onco-Anesthesia and Perioperative Care (SOAPC) thereby came out with an advisory for safe perioperative management of cancer surgery during this challenging time of the COVID-19 pandemic.

Inflammatory Pseudotumor of the Renal Pelvis.

Background: Inflammatory pseudotumor of the kidney is a rare disease of unknown etiology. There are no specific clinical or radiologic findings. The lesion can mimic renal cell carcinoma or transitional cell carcinoma depending on the site of involvement. These tumors, if diagnosed correctly, may respond to medical management. We present a case in which an inflammatory pseudotumor of the renal pelvis was misdiagnosed as a transitional cell carcinoma and unwarranted surgical intervention was performed. Case Presentation: A 39-year-old man presented with left flank pain and gross hematuria. On MRI, there was a hypointense 2.4 × 1.8 cm lesion involving the left renal pelvis. The urine cytology and biopsy of the lesion were inconclusive. On follow-up cans the lesion increased in size and patient had repeated hematuria. The lesion was clinically presumed to be a transitional cell carcinoma of the left renal pelvis. A laparoscopic left side nephroureterectomy along with bladder cuff excision and para-aortic lymphadenectomy was performed. The histology report revealed the lesion to be inflammatory pseudotumor of the renal pelvis. Conclusion: Inflammatory pseudotumor should always be considered in differential diagnosis of pelvic tumors, especially when image findings and biopsies are inconclusive.

Short-term Alteration of Renal Function and Electrolytes after Percutaneous Nephrolithotomy.

PURPOSE: To analyse the changes in renal function and serum electrolytes in the early post-operative period ofpercutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: A total of 110 patients with normal renal function, who underwent PCNL in our institutewere evaluated prospectively. Haemoglobin percentage, packed cell volume, blood urea nitrogen, serum creatinineand serum electrolytes, namely sodium, potassium, chloride and ionized calcium were measured on the day beforesurgery and after 72 hours of the procedure. Renal function was assessed by Cockcroft-Gault formula and estimatedglomerular filtration rate was calculated by modification of diet in renal disease formula. RESULTS: Serum creatinine increased significantly from a mean value of 0.89 ± 0.199 mg/dL to 0.96 ± 0.252 mg/dL(P = 0.0002) and both creatinine clearance and estimated glomerular filtration rate experienced a significant fall -from a median value (interquartile ranges) of 82.99 (72.37 to 96.88) mL/min to 75.38 (63.89 to 94.05) mL/min incase of creatinine clearance (P = 0.0004) and from a mean value of 95.18 ± 19.87 mL/min/1.73 m2 to 89.30 ± 23.14mL/min/1.73 m2 in case of estimated glomerular filtration rate (P = 0.003). Furthermore, there were significantdrops in both haemoglobin percentage and packed cell volume. There were no significant alterations in serum electrolytes- sodium and potassium (mmol/L) [Median (IQR)] changed from a pre-operative figure of 137.5 (134.0 to140.0) and 3.85 (3.60 to 4.10) to a post-operative value of 138 (135.0 to 140.0) and 3.85 (3.50 to 4.10) respectively. CONCLUSION: Even though there is no significant variation in serum electrolytes, PCNL causes significant reductionin renal function in the early post-operative period.

Robotic Donor Nephrectomy: The Right Way Forward.

Donor nephrectomy is an extremely challenging procedure. The stakes are high, as two lives-the donor and the recipient-depend on it. Robotic donor nephrectomy has an edge over a laparoscopic approach.

Solitary fibrous tumor of the ovary.

Solitary fibrous tumors commonly occur in the pleura and are rare elsewhere, especially in the female genital system. We present a case of a solitary fibrous tumor arising from the ovary in a young female in the reproductive age group. The tumor could be excised laparoscopically. We also describe the histopathological and immunohistochemical features that can help establish its diagnosis.

Bone in the Stone.

Heterotrophic bone formation in the pelvicalyceal system acting as a nidus for stone formation is a rare phenomenon. We report a case of a 16-year-old female who, during percutaneous nephrolithotomy for right renal calculi, was found to have bone attached to the renal pelvic epithelium over which stone formation had occurred.
