Clinical Consultation Guide: Nerve-sparing Techniques for Retroperitoneal Lymph Node Dissection in Testicular Cancer.

Reptroperitoneal lymph node dissection (RPLND) is associated with a risk of morbidity and ejaculatory dysfunction. Nerve-sparing RPLND shows promise in preserving ejaculation alongside oncological efficacy. Laparoscopic and robot-assisted modalities are feasible with good outcomes, highlighting the need for ongoing scientific research and refinement of surgical skills.

Guillain-Barré Syndrome following intravesical Bacillus Calmette-Guérin therapy for bladder cancer: a rare and intriguing case report.

Intravesical Bacillus Calmette-Guérin (BCG) therapy is a standard treatment for non-muscle invasive bladder cancer, but some patients experience side effects that lead to treatment discontinuation. Local side effects are typically mild, while systemic side effects can be severe and life-threatening. BCG therapy has immunotherapy effects on bladder cancer, but the mechanism is not fully understood. Due to its effect on the immune system, patients may also develop rare autoimmune complications, such as neuropathy. This case report suggests a potential association between BCG therapy and Guillain-Barré Syndrome (GBS), as a patient developed GBS after receiving intravesical BCG therapy for invasive bladder cancer.

Choosing the best way for urinary decompression and developing a novel predictive model for septic shock using SOFA in these patients.

OBJECTIVES: To identify predictive factors for the development of sepsis/septic shock postdecompression of calculi-related ureteric obstruction using the Sequential Organ Failure Assessment (SOFA) score and to compare clinical outcomes and odd risk ratios of patients developing sepsis/septic shock following the insertion of percutaneous nephrostomy (PCN) versus insertion of retrograde ureteral stenting (RUS). METHODS: Clinico-epidemiological data of patients who underwent PCN and/or RUS in two institutions for calculi-related ureteric obstruction were retrospectively collected from January 2014 to December 2020. RESULTS: 537 patients (244 patients in PCN group, 293 patients in RUS group) from both institutions were eligible for analysis based on inclusion and exclusion criteria. Patients with PCN were generally older, had poorer Eastern Cooperative Oncology Group status, and larger obstructive ureteral calculi compared to patients with RUS. Patients with PCN had longer durations of fever, the persistence of elevated total white cell and creatinine, and longer hospitalization stays compared with patients who had undergone RUS. RUS up-front has more unsuccessful interventions compared with PCN. There were no significant differences in the change in SOFA score postintervention between the two interventions. In multivariate analysis, the higher temperature just prior to the intervention (adjusted odds ratio [OR]: 2.039, p = 0.003) and Cardiovascular SOFA score of 1 (adjusted OR:4.037, p = 0.012) were significant independent prognostic factors for the development of septic shock postdecompression of ureteral obstruction. CONCLUSIONS: Our study reveals that both interventions have similar overall risk of urosepsis, septic shock and mortality rate. Despite a marginally higher risk of failure, RUS should be considered in patients with lower procedural risk. Patients going for PCN should be counseled for a longer stay. Post-HDU/-ICU monitoring, inotrope support postdecompression should be considered for patients with elevated temperature within 1 h preintervention and cardiovascular SOFA score of 1.

The efficacy of on-demand sedation colonoscopy: a STROBE-compliant retrospective cohort study.

BACKGROUND: Colonoscopy has been routinely performed with sedation. Previous studies showed that on-demand sedation colonoscopy is acceptable in patients. We aim to compare the clinical outcomes of patients undergoing colonoscopy with and without sedation. METHODS: A prospectively collected retrospective matched cohort study was performed. 290 consecutive patients who underwent colonoscopy without sedation were included into the study. Another 290 patients who underwent colonoscopy with sedation were then selected based on matched sex and age group distribution. Data were collected in a prospective database. Age, sex, race, and procedural variables were collected. Outcomes analyzed included adenoma detection rate, Boston bowel preparation scores, time spent in the recovery room, cecal intubation time, and presence of pain during colonoscopy. RESULTS: A total of 580 patients were included in the study. Of the 290 patients who underwent colonoscopy without sedation, 10 patients (3.45%) required sedation to be administered to complete the scope. Intention-to-treat analysis was performed. Multivariate analysis demonstrated that the administration of sedation was a significant predictor of prolonged recovery time (increase in 34.76 min, 95% CI 29.56-39.55, p < 0.001). Comparing the group who underwent colonoscopy without sedation to the group who underwent colonoscopy with sedation, there was no statistically significant difference in mean cecal intubation time (11.28 vs. 10.38 min, p = 0.129), adenoma detection rates (25.1 vs. 35.8%, p = 0.060), percentage of patients who experienced no pain at all during the procedure (93.5 vs. 93.5%, p = 1.000), and Boston bowel preparation scores (2.23 vs. 2.34, p = 0.370). CONCLUSIONS: Our data suggest that on-demand sedation colonoscopy can be performed in patients, with a significant decrease in time spent in the recovery room prior to discharge. Cecal intubation time, adenoma detection rates, and percentage of patients experiencing no pain at all during the procedure were similar in both groups of patients.

Linitis plastica of the rectum secondary to metastatic prostate cancer: A case report of a rare presentation and literature review.

Linitis plastica is a rare tumor with poor prognosis. It is a circumferentially infiltrating intramural tumor which can result in rigid, nondistensible thickening of the affected organ. It most commonly affects the stomach, followed by the rectum, and can be due to primary or secondary cancer. Secondary rectal linitis plastica (RLP) caused by metastatic cancers has been reported from the stomach, breast, gallbladder, urinary bladder, and very rarely, the prostate, with only <5 reported cases in the literature. We report the case of a 66-year-old man who presented with altered bowel habit and loss of weight, with elevated prostate-specific antigen of 180.6 ng/mL. Sigmoidoscopy showed thickened rectal mucosa, and biopsy was negative for malignancy. Magnetic resonance imaging showed circumferential wall thickening, "target sign" appearance suggestive of RLP, PIRADS 5 lesion with extraprostatic extension, infiltrating bilateral seminal vesicles, and right neurovascular bundle. Repeat colonoscopy was performed under anesthesia, and deeper biopsy revealed poorly differentiated metastatic prostate adenocarcinoma. This case report highlights the atypical presentation of metastatic prostate cancer secondary to RLP, the rarity of this condition, and emphasizes the importance of deeper biopsy in RLP due to disease involvement predominantly in the submucosa and muscularis propria layers.

Wunderlich syndrome secondary to cyst rupture and concurrent anticoagulation.

Wunderlich syndrome (WS) is a rare triad of flank pain, flank mass and hypovolemic shock and is classically attributed to angiomyolipomata or neoplasms. Treatment is guided by clinical severity: conservative, selective arterial embolization, or nephrectomy. We report an atypical case of a 69-year old man with a pre-existing 9 cm left renal tumor who developed WS secondary to anticoagulation and simple cyst rupture from his contralateral kidney, complicated by abdominal compartment syndrome with hemodynamic instability despite inotropic support and robust resuscitation. Early recognition and source control via radical nephrectomy were essential in securing a positive outcome.

A case report of bleeding from a duodenal varix: Rare cause of upper gastrointestinal bleeding.

INTRODUCTION: Ectopic variceal bleeding is uncommon, accounts for 2-5% of variceal bleeding, of which 17% is in duodenum. PRESENTATION OF CASE: 62-year-old lady with newly diagnosed liver cirrhosis on admission, presented with severe upper gastrointestinal bleeding (UGIB), was ultimately diagnosed with bleeding duodenal varices with single-balloon enteroscopy, after multiple oesophagogastroduodenoscopies (OGDs) and CT scans which failed to identify the varices. She was treated successfully with duodenectomy. DISCUSSION: Endoscopy and CT angiography remain the diagnostic modalities of choice. However, diagnosis can be difficult as evidenced by three OGDs and two CTMAs yielding negative findings in this case. Endoscopic diagnosis is challenging and often delayed due to its rarity and unusual location. CONCLUSION: Ectopic variceal bleeding is a rare but important cause of UGIB. Diagnosis is challenging and management of this condition should take a multidisciplinary approach, involving experienced gastroenterologists, interventional radiologists and surgeons. Endoscopic ligation or sclerotherapy is the first-line of treatment.
