First Global Report of Catastrophic Results Due to Internal Herniation of Roux Limb in the Space Between the Gastric Pouch and Band: a Series of 3 Cases of Banded Roux-en-Y Gastric Bypass (BRYGB).

BACKGROUND: Banded Roux-en-Y gastric bypass (BRYGB) is associated with complications known with the bypass along with specific complications related to the band. Roux-limb gangrene, due to herniation between the gastric pouch and band, however, has no mention in literature. METHODS: We report this potentially fatal complication of BRYGB and its management in a series of 3 patients. RESULTS: All 3 patients were women, 35-45 years, with a BRYGB (roux limb-150 cm, biliopancreatic limb-100 cm) using a MiniMizer or a Fobi ring with 2-point fixation to the gastric pouch 2 cm above the gastrojejunostomy. All patients presented 3-4 years post-BRYGB, with an average total body weight loss (TWL%) of 41.28%. To discuss video of a single case, a 35-year-old female presented with abdominal pain, hematemesis and signs of abdominal tenderness and guarding. X-Ray abdomen showed distended small bowel loops and CT-scan revealed ischemic small bowel loops with free fluid. Diagnostic laparoscopy showed alimentary/roux limb (AL) gangrene, from the gastrojejunostomy to the jejunojejunostomy. The entire AL had herniated between the gastric pouch and band which had formed an obstructive ring around the herniated bowel loop and led to compromise of blood supply and gangrene. Resection of gangrenous bowel with reversal of BRYGB was done. CONCLUSION: Early diagnosis and timely management may save a patient from gangrene. It also raises questions: Is a 2-point fixation of the band to the gastric pouch insufficient? Does a longer roux limb make it prone to herniating in the space between the gastric pouch and band?

Caregiver distress: A mixed methods evaluation of the mental health burden of caring for children with bladder exstrophy.

Introduction: Caring for children with bladder exstrophy-epispadias complex (BEEC) exacts a long-term emotional toll on caregivers. Previous studies leave a gap in understanding the impact that caring for a child with BEEC has on caregivers in low- and middle-income countries (LMIC). We hypothesize that families and caregivers experience psychological distress that has long gone unaddressed. Materials and methods: From 2018 to 2020, researchers conducted a multi-method evaluation of caregiver distress with participants recruited as part of the annual International Bladder Exstrophy Collaboration based in Ahmedabad, Gujarat, India. In 2018, pilot data was collected through cognitive interviews. In 2019, researchers conducted structured interviews predicated on themes from the previous year, which subsequently prompted formal mental health screenings in 2020. Caregivers who reported suicidal thoughts were immediately referred for intervention. Results: In 2018, caregivers described the primary source of stigma arose from their village (n = 9, 26.5%). Caregivers also identified long-term concerns (n = 18, 52.9%), including future fertility and marital prospects, as sources of anxiety. In 2019, caregivers substantiated preliminary findings with the primary source of anticipated (n = 9, 31%) and experienced (n = 19, 65.5%) stigma again stemming from their communities. Both cohorts identified the collaboration as a positive source of support (n = 23, 36.5%). In 2020, caregivers stated decreased emotional wellbeing as number of subsequent repairs increased (n = 54, 75%, p = 0.002). Caregivers of children who underwent initial surgery within 5 years of screening reported higher anxiety (n = 46, 63.8%) and this was exacerbated as the number of subsequent repairs increased (p = 0.043). Conclusion: Complex, long-term course of care, including additional surgeries, significantly impacts caregiver distress in the LMIC setting. Screening for caregivers of children with complex congenital anomalies, like BEEC, should be an essential element of any comprehensive effort to alleviate the global burden of disease.

Contemporary Incidence and Predictors of Occult Inguinal Lymph Node Metastases in Men With Clinically Node-negative (cN0) Penile Cancer.

OBJECTIVE: To (1) examine the contemporary incidence of occult inguinal LN metastases and (2) identify predictors of occult inguinal LN metastases to improve selection of cN0 patients for inguinal lymphadenectomy (ILND). METHODS: We identified 590 men with cTany cN0 cM0 penile cancer who underwent partial/radical penectomy and ILND from 2006-2016 in the NCDB. Rates of pN+ disease were examined, and a multivariable regression model was constructed to identify features associated with pN+ disease. RESULTS: Tumors were ≤pT1 in 21%, pT2 in 43%, and pT3/pT4 in 24% of patients. A median of 15 (IQR 8-22) LNs were removed at ILND. The overall pN+ rate was 24% and did not vary over the study period. The pN+ rate, stratified by pT stage, varied from 18-33%. On multivariable analysis, only higher tumor grade (OR 2.16; P = 0.02 for grade 2; OR 2.81; P = 0.005 for grade 3-4, versus grade 1) and lymphovascular invasion (OR 3.12; P <0.001) were independently associated with pN+ disease, whereas pT stage was not. CONCLUSION: The contemporary rate of occult LN metastases in men with cN0 penile cancer remains high at approximately 24%. Our results suggest that high tumor grade and/or lymphovascular invasion are better determinants of lymph node involvement than primary tumor stage.

The Role of Lymphadenectomy in Patients with Advanced Renal Cell Carcinoma.

The role of lymph node dissection (LND) in the management of renal cell carcinoma (RCC) is controversial. LND serves an indisputable staging role by providing pathologic nodal stage. However, while earlier observational studies had suggested a survival benefit to LND, more recent observational evidence and a randomized trial do not support a survival benefit. The majority of patients with isolated lymph node involvement appear to harbor occult metastatic disease. Still, LND is not associated with increased perioperative morbidity when performed in experienced centers. LND may therefore play a predominantly staging role in patients at increased risk of lymph node metastases.
