Retrograde intussusception causing small bowel obstruction in a 35 year old Female patient following a Roux en Y Bypass. Case report.

INTRODUCTION: Intestinal intussusception is an uncommon entity when preceded by Roux en Y gastric bypass. Retrograde intussusception is an enigmatic phenomenon characterized by reversely intussuscepted intestinal loop that may involve any piece of the Roux en Y limbs. Computed Tomography is gold standard for diagnosis. Surgical management is highly debatable. CASE PRESENTATION: A 35 years old female known for morbid obesity, post roux en Y gastric bypass since 5 years with 100 % excess weight loss presenting for on-off episodes of small bowel obstruction symptoms. She was diagnosed laparoscopically for retrograde intussusception that was reduced easily with closure of Peterson's pouch due to high suspicion of an internal hernia. She did well postoperatively and followed up adequately with no recurrence of her symptoms. CONCLUSION: Retrograde intussusception remains an interesting uncommon phenomenon in the horizon of the roux en Y gastric bypass surgeries. Several surgical options were discussed in the last 12 years and they are still debatable.

Bilateral inguinal masses or hernias in a female teenager with delayed menarche: Think of Complete Androgen Insensitivity Syndrome (CAIS), a case report.

INTRODUCTION: Complete Androgen Insensitivity Syndrome (CAIS) is a rare sexual development disorder with X-linked recessive inheritance. It is prevalent in 1:20400 to 1:99000 of female phenotypes, yet characterized by an XY genotype. Cases of CAIS usually present with primary amenorrhea together with unilateral/bilateral inguinal hernias. CASE PRESENTATION: A previously healthy 19 year old sexually inactive girl presents to our clinics for delay in menarche and bilateral palpable inguinal masses 3 years ago. She has normal female habitus, tanner stage 3 and external female genetalia with sparse pubic hair. She has a family history of 2 aunts (mother side) having infertility with Bilateral inguinal hernias surgery. Hormonal tests showed male range testosterone levels. MRI showed bilateral inguinal masses with Mullerian structures agenesis and a misdiagnosis of Mayer-Rokitansky-Küster-Hauser syndrome (MRHKS) was interpreted. While karyotype showed XY genotype. She is then planned for bilateral orchiectomy. Final pathology of the 2 specimens taken showed testicular tissue correlating with CAIS. DISCUSSION: CAIS patients presents with near normal female external genetalia, absence of Mullerian structures, taller status than regular females and testosterone levels equal or higher than male levels. Different imaging types together with karyotyping are crucial in diagnosing and differentiating CAIS from other entities such as MRHKS and Swyer syndrome. Treatment debates include prepubertal or postpubertal gonadectomy correlating with the age related malignancy rate and site of testis followed by Hormonal replacement therapy. CAIS management needs a multidisciplinary approach and decisions by the patient or his family sometimes. CONCLUSION: CAIS must be suspected in any case of young females with bilateral inguinal hernias as in our case, and precise diagnostics tests such as MRI and Karyotyping must be done followed by biopsy or excision for diagnosis and then adequate treatment. Hormonal therapy must be continued after gonadectomy that is best to be postpubertal.

Gallbladder Volvulus: An Unusual Presentation.

BACKGROUND Gallbladder torsion is a rare entity of acute abdomen that can be fatal if not diagnosed and treated promptly. It presents in a multitude of ways but the most common is a presentation similar to acute cholecystitis. Diagnosis can be made clinically by abdominal ultrasound with Doppler flow, and treatment is detorsion with cholecystectomy. CASE REPORT A 57-year-old female presented to the emergency department with severe abdominal pain, bilious vomiting, and loose stools. An initial diagnosis of gastroenteritis was made, however, the patient did not respond to symptomatic treatment and continued having pain, nausea and vomiting. Abdominal ultrasound revealed signs of acute cholecystitis and the patient underwent an open cholecystectomy where the gallbladder was found to be black, gangrenous, and voluminous due to torsion. Detorsion and cholecystectomy were performed without any complications. CONCLUSIONS Gallbladder torsion is a rare entity of acute abdomen that can be fatal if not diagnosed and treated promptly. Gallbladder torsion should be a part of the differential diagnosis of any patient presenting with an acute abdomen and unusual symptoms of acute cholecystitis.
