Gastric Outlet Obstruction as a presentation of Metastatic Squamous Cell Carcinoma of the Bladder: A case report and review of the literature.

INTRODUCTION: Gastric outlet obstruction presents with a range of symptoms which include abdominal pain, early satiety, weight loss and vomiting caused obstruction secondary to tumors from outside the gastrointestinal tract or due to motility disorders. Bladder cancer is rarely associated with Gastric outlet obstruction. It usually presents with painless hematuria and urinary symptoms. Squamous cell carcinoma is a subtype of bladder malignancies that tends to present at a later stage and is associated with poorer prognosis in terms of metastasis and survival. CASE PRESENTATION: We present the case of a 79-year-old man, non-smoker, who presented to the emergency department with gastric outlet obstruction and was found to have non-bilharzial squamous cell carcinoma of the bladder metastatic to the retroperitoneal lymph nodes causing duodenal and small bowel obstruction. CLINICAL DISCUSSION: Squamous cell carcinoma of the bladder, tends to present at later stages and spread to adjacent organs or spread through lymphatics to lymph nodes, liver, bone, brain, lungs, and the gastro-intestinal tract. Diagnosis is made through cystoscopy, pathology and imaging. Non-Bilharzial Squamous cell carcinoma of the bladder is associated with increased morbidity and mortality than its Bilharzial counterpart. CONCLUSION: This is a unique case of non-bilharzial squamous cell carcinoma of the bladder, metastatic to retroperitoneal lymph nodes that lead to compression of the duodenum and small bowels and eventual gastric outlet obstruction. There are few reports of gastro-intestinal obstruction secondary to bladder cancer, however this is the first case metastatic non-bilharzial Squamous cell carcinoma of the bladder presenting as gastric outlet obstruction.

First prospective clinical assessment of the ILY® robotic flexible ureteroscopy platform.

PURPOSE: To present the initial prospective clinical assessment of the ILY® robotic ureteroscopy manipulator platform, focusing on its safety and effectiveness. METHODS AND MATERIALS: Data gathered from 31 kidney units which underwent elective robotic flexible ureteroscopy (FURS) for renal stone management utilizing the ILY® robotic system. Patient demographics, stone characteristics, surgical durations, perioperative and post-operative complications, and follow-up parameters were collected. Our primary outcome was evaluating the efficacy and safety of the ILY® robotic ureteroscopy for treating kidney stones. Therefore, we analyzed complication rates, surgical durations, and the stone-free rate during follow-up. RESULTS: Our cohort consisted of 29 patients, presenting with 45 stones with a median volume of 736.22 mm3. The median operation time was 85 min, accompanied by 3 min for robot draping, 3.5 min for robot docking, 48 min of console operation, and lasing time of 36.75 min. Post operative stay for all patients was 1 day, while complications were observed in 9.68% of cases. Notably, all complications were classified as CVD (Clavien-Dindo) class 1 due to pain requiring emergency department visit. The stone-free rate achieved was 93.55%, and none of the patient required reoperation for the treated stone. CONCLUSION: In the first prospective clinical experience of the ILY® robotic FURS, we demonstrated its efficacy and safety. To further investigate its clinical practical value, additional investigations are warranted, including direct comparative analyses with manual flexible ureteroscopy techniques.

Laparoscopic retroperitoneal heminephrectomy for renal cell carcinoma in horseshoe kidney: a case report and review of the literature.

INTRODUCTION: In this case report, we demonstrate our technique of a retroperitoneal laparoscopic heminephrectomy for a T1b right hilar tumor in a horseshoe kidney. CASE PRESENTATION: A 77-year-old Vietnamese woman presented to the hospital because of right flank pain. On presentation, her serum creatinine was 0.86 mg/dL and glomerular filtration rate was 65.2 mL/minute/1.73 m2. According to her renal scintigraphy, glomerular filtration rates of the right and left moieties were 24.2 and 35.5 mL/minute, respectively. Computed tomography imaging demonstrated a 5.5 × 5.0 cm solid hilar mass with a cT1bN0M0 tumor stage was in the right moiety. After discussion, the patient elected a minimally invasive surgery to treat her malignancy. The patient was placed in a flank position. We used Gaur's balloon technique to create the retroperitoneal working space, and four trocar ports were planned for operation. Three arteries were dissected, including two arteries feeding the right moiety, one artery feeding the isthmus, and one vein, which was clipped and divided by Hem-o-lok. The isthmusectomy was performed with an Endostapler. Consequently, the ureter was clipped and divided. Finally, the whole right segment of the horseshoe kidney was mobilized and taken out via the flank incision. RESULTS: The total operative time was 250 min with an estimated blood loss of 200 mL. The patient's serum creatinine after surgery was 1.08 mg/dL, and glomerular filtration rate was 49.47 mL/minute/1.73 m2. The patient was discharged on postoperative day #4 without complication. Final pathologic examination of the tumor specimen revealed a Fuhrman grade II clear cell renal cell carcinoma, capsular invasion, with negative surgical margins. After a three-month follow-up, the serum creatinine was 0.95 mg/dL, and glomerular filtration rate was 57.7 mL/minute/1.73 m2. Local recurrence or metastasis was not detected by follow-up computed tomography imaging. CONCLUSIONS: Retroperitoneal laparoscopic heminephrectomy is a safe and feasible technique for patients with renal cell carcinoma in a horseshoe kidney and may be particularly useful in low income settings without access to robotic technology.

Syrian Refugees Seeking Hospital Care in Beirut: A Cross-Sectional Study of Reasons for Hospital Admissions.

INTRODUCTION: Lebanon has the highest Syrian refugee density worldwide. The influx of Syrian refugees has had various impacts on Lebanon, with one of the most significant effects observed in the already exhausted healthcare system. This study aimed to determine the reasons for hospitalization among registered Syrian refugees in Beirut who were admitted to Rafik Hariri University Hospital (RHUH) between December 2017 and June 2020. METHODS: Data from 7,480 diagnosed cases were collected from the RHUH archives between December 2017 and June 2020 and were analyzed using SPSS (IBM Corp., Armonk, NY, USA). The collected data included information related to demographics, admission date, primary diagnosis, and other related medical problems. Variations and correlations were then tested. RESULTS: Of the cases, 73.4% were females; the mean age was 28 ± 16.23 years. Fifty-seven percent of the admitted cases were solely due to pregnancy, childbirth, and puerperium reasons, and 91.14% of the deliveries were single deliveries by cesarean section. Common reasons for hospitalization were injuries (5.8%) and diseases of the digestive system (6.8%), circulatory system (4.7%), and respiratory system (4.4%). Non-communicable diseases (NCDs) constituted 61% of all hospital admissions, while only 6.6% belonged to communicable diseases. Reasons for hospitalization and the type of diagnosed diseases were associated with gender and age groups (p-values <0.001). CONCLUSION: The major reasons for hospitalization among Syrian refugees were related to pregnancies and NCDs. The burden of the Syrian refugee influx on the Lebanese healthcare system can be alleviated by improving community health education, public health services, and conditions for refugees.

Concurrent radical cystectomy and nephroureterectomy indications and outcomes: a systematic review and comparative analysis.

Introduction: Urothelial carcinoma can arise from the urinary bladder or from the upper urinary tract. In some instances, urinary bladder cancer (UBC) and upper tract urothelial carcinoma (UTUC) can be concurrently diagnosed, necessitating a combined radical cystectomy (RC) with radical nephroureterectomy (RNU). A systematic review was done on the combined procedure exploring outcomes and indications, in addition to a comparative analysis between the combined procedure and cystectomy alone. Methods: For the systematic review, three databases (Embase, PubMed, and Cochrane) were queried, selecting only studies that included intraoperative and perioperative data. For the comparative analysis, using the NSQIP database, CPT codes for RC and RNU were used to identify two cohorts, one with RC and RNU and one with RC alone. A descriptive analysis was performed on all preoperative variables, and propensity score matching (PSM) was performed. Postoperative events were then compared between the two matched cohorts. Results: For the systematic review, 28 relevant articles were included amounting to 947 patients who underwent the combined procedure. The most common indication was synchronous multifocal disease, the most common approach was open surgery, and the most common diversion technique was using an ileal conduit. Almost 28% of patients required blood transfusion and remained in the hospital for an average of 13 days. The most common postoperative complication was prolonged paralytic ileus. For the comparative analysis, 11,759 patients were included of which 97.5% underwent RC only and 2.5% underwent the combined procedure. After PSM, the cohort that had undergone the combined procedure showed an increased risk of renal injury, increased readmission rates, and increased reoperation rates. Whereas the cohort that had undergone RC only showed an increased risk of deep venous thrombosis (DVT), sepsis, or septic shock. Conclusion: A combined RC and RNU is a treatment option for concurrent UCB and UTUC that should be cautiously utilized as it is associated with high morbidity and mortality. Patient selection, discussion of the risks and benefits of the procedure, and explanation of the available treatment options remain the most important pillars in managing patients with this complex disease.

Gastric outlet obstruction - looking for a syndrome: Bouveret or Mirizzi?

INTRODUCTION AND IMPORTANCE: Gastric outlet obstruction can result from any pathological process that causes intrinsic blockage or extrinsic pressure on the distal stomach and duodenum. Gallstone related gastric outlet obstruction is a well-known entity classically due to a cholecystoenteric fistula formation. CASE PRESENTATION: We present here a case of a 36-year-old man who presented with right upper quadrant abdominal pain associated with marked nausea and vomiting. Abdominal CT scan done in the emergency department revealed a large impacted infundibular gallstone with signs of acute cholecystitis, associated with prominent gastric distention. Gastric outlet obstruction was due to stenosis at the duodenal level from external compression by the large impacted stone with no evidence of fistula. Laparoscopic cholecystectomy was performed with total resolution of symptoms. CLINICAL DISCUSSION: Gastric outlet obstruction can be secondary to many etiologies, and notably gallstone disease. Classically this is due to formation of a cholecystoenteric fistula and intrinsic obstruction by the migrated stone. Our case is unique in that a large impacted infundibular gallstone caused gastric outlet obstruction with absence of any fistula or gallstone migration. CONCLUSION: Gastric outlet obstruction due to external compression by a non-migrated gallstone is a rare undescribed entity. Surgical treatment should not be delayed to prevent complications and fistula formation.

A 12-Year Comparative Analysis of Hodgkin and Non-Hodgkin Lymphomas in Lebanon: Trend Characteristics and 10-Year Projections.

Background  Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) are two common malignancies worldwide and in Lebanon. Analysis of their trends plays a crucial role to better understand their origins and risk factors. This study will probe incidences of both types of lymphomas from 2005 to 2016, aiming to compare between the two malignancies according to age and sex and plot projections until 2026. Methods HL and NHL cases from 2005 to 2016 were collected from the National Cancer Registry of Lebanon. Data was stratified according to age and sex. Age-specific and age-standardized incidence rates were analysed using joinpoint regression; 10-year projections were predicted based on logarithmic models. Results Between 2005 and 2016, NHL was significantly more common than HL. NHL was higher in both genders. HL showed a bimodal age distribution while NHL peaked in elderly patients. NHL incidence rates in males increased significantly from 2005 to 2014 while HL incidence rates showed an insignificant rise. Over the next 10 years, NHL and HL cases are expected to increase in Lebanon. Conclusion HL and NHL are on the rise in Lebanon. Extensive research into the main factors contributing to these lymphomas is crucial in the fight against them. More efforts must be done by the government and health organizations to better control the disease.
