ABSTRACT
Background: Transverse colon volvulus is an uncommon cause of bowel obstruction. The total number of cases reported in the literature is 100. It constitutes a surgical emergency since it can lead to bowel infarction, peritonitis, and death if not diagnosed at once. It seemed appropriate to report this case that was treated at the Department of Visceral Surgery A, Lucien Hussel Hospital in Vienne, France Case presentation: We report a rare case of transverse colon volvulus in a 42-year-old Arabic man, with no particular history, who presented to our emergency department with a 5-day history of constipation, progressive abdominal pain, nausea, and vomiting. His last bowel movement had been 3 days ago. Abdominal radiography showed a large bowel obstruction with a “U-shaped” loop in the left upper abdomen. Abdominal computed tomography was not performed because of impaired renal function. He was operated on urgently after conditioning and the diagnosis of a transverse colon volvulus was done intraoperatively. Rotated in a 360° clockwise direction on its mesentery, the bowel was intact without signs of ischemia. An extended right hemicolectomy was carried out with end-to-side ileocolic anastomosis. Through this case, we will try to discuss its physiopathology, etiologies, diagnosis, and management in emergencies. Conclusion: This case is unusual because no etiological factor has been found. Its diagnosis can be difficult and management effectiveness remains controversial. It is important to highlight this case and those of the literature, as many surgeons may have never seen a case of transverse colon volvulus. Volvulus of the transverse colon may therefore not be considered in the differential diagnosis of recurrent intermittent abdominal pain or acute intestinal obstruction. Prompt recognition with emergency intervention constitutes the key to a successful outcome.

ABSTRACT
Objective: To present the epidemiological, clinical and histological aspects of bladder cancer at the National Hospital of Zinder (Niger). Materials and methods: This is a retrospective, descriptive and analytical study covering the period from June 2014 to January 2022concerning the files of patients followed up for bladder cancer. The patients come from three regions bordering Zinder (Maradi, Agadez, Diffa). The parameters studied were epidemiology, age, sex, clinical signs, paraclinical tests, and histological results. Results: A total of 6724 patients were consulted during the period, which brings to 1.23% the incidence of bladder cancer at Zinder national hospital (HNZ). The median age of patients was 56.83 years with extremes of 24 and 77 years. The sex ratio was 7/1. A history of chronic smoking for an average of 5 pack-years was found in 8 cases (9.63%). Among the other risk factors, a history of urinary schistosomiasis in 58 cases (69.87%). The reasons for consultation were: total hematuria 63 cases (76.41%), permanent pollakiuria 8 cases (9.32%), acute urine retention 7 cases (8.33%), renal failure 3 cases (3.54%), exophytic tumor 2 cases (2.40%). Additional diagnostic tests were: ultrasound, cystoscopy, computed tomography (CT). Histology found 66 cases (79.51%) of squamous cell carcinoma, 15 cases (18.07%) of urothelial carcinoma and 2 cases (2.42%) of adenocarcinoma.

ABSTRACT
A peculiar case of ischuria secondary to Zinner syndrome. A complete excision via laparoscopic approach given a 100 percent symptomatic relief is a safe and effective. Symptomatic congenital cysts require an appropriate management. Case Description: Case of 21 years male presented in urology unit with features of obstructive uropathy, acute urinary retention and severe lower abdominal pain on evaluation found to had left kidney agenesis and left seminal vesical cyst [1]. A Three port laparoscopic transperitoneal approach performed and left side seminal vesical cyst removal done. The peritoneum was incised between the bladder and the rectum to reveal the left seminal vesicle, which was resected from the surrounding tissue and removal of the cyst done. Discussion: Aim of the study was to show the advancement and usefulness of the laparoscopic approach with short hospital stay and painless procedure, minimal blood loss. Procedure lasted for 60 mins. Unrecordable post intraoperative complications. Patient had been discharged after 36 hours after the procedure, on follow up patient is asymptomatic for 24 months of the procedure. Symptomatic Zinner syndrome with appropriate identification and laparoscopic approach and magnified view better than open and other invasive techniques should be a method of choice in treatment of the congenital seminal vesical cyst and currently a golden surgical standard.
