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.

Laparoscopic ileo-cecectomy for ileo-ceco-colic double intussusception due to a cecal adenoma harboring multifocal high grade dysplasia in a 24 years old male: A case report.

INTRODUCTION: Intestinal Intussusception is defined as invagination of the intussusceptum into the intussuscepien, and is responsible of 1% of all bowel obstructions. It is rare in adults and common in children. It is mostly due to organic causes in adults that form lead points. Enteroenteric intussusception is the most common type. Signs and symptoms are more classic in children but nonspecific in adults. Usually diagnosis is made intraoperatively, while abdomino-pelvic CT scan is the best preoperative imaging modality. Intestinal Intussusception in adults, especially when the colon is involved, is best treated by surgical resection. CASE PRESENTATION: A 24 years old previously healthy male with no surgical or documented familial history presenting for severe crampy abdominal pain and distention, obstipation and palpable right lower quadrant abdominal mass. Abdominal Multi-slice CT diagnosed an ileo-colic intussusception without signs of bowel suffering. Laparoscopic ileo-cecetomy. Final Pathology showed a 4 cm cecal tubular adenomatous polyp with multifocal high grade dysplasia. CONCLUSION: Intestinal intussusception in adults is an interesting rare entity that have the interest of general surgeons. Malignant lesions can be lead-points and they form a great counterpart among other colonic lesions. Minimally invasive laparoscopic surgery is gaining interest in management, and surgical resection remains the gold standard while reduction before surgery is debatable and can be considered in selected cases.

Giant parathyroid adenoma presenting with a pathological left clavicular fracture: An extremely rare case report.

INTRODUCTION: Parathyroid gland has a distinct physiologic and endocrinologic role in the body system. Primary hyperparathyroidism is the most common cause of hypercalcemia with a marked female dominance. It is characterized by hypercalcemia, hypophosphatemia and elevated parathyroid hormone. Parathyroid adenoma, parathyroid hyperplasia and parathyroid carcinoma form the differential diagnosis. Giant parathyroid adenomas are rarely symptomatic than non-giant parathyroid adenomas and parathyroid carcinoma. CASE PRESENTATION: A 41 years old previously healthy male patient with undetectable surgical and familial history presenting with left clavicle fracture by mild trauma. He was diagnosed for primary hyperparathyroidism after the finding of multiple bony lesions and elevated serum calcium and Parathyroid hormone. Preoperative imaging aided in diagnosis of a parathyroid lesion and secondary bone resorption lesions (brown tumors). After adequate medical treatment and preparation, selective right lower parathyroidectomy was held, and the final pathology came with a giant parathyroid adenoma. CONCLUSION: Primary hyperparathyroidism should be suspected when dealing with a hypercalcemic patient having osteolytic bony lesions. Distinguishing Parathyroid adenoma from carcinoma is a challenging and essential preoperative step in planning and surgical procedure.

Infarcted accessory spleen due to segmental portal hypertension.

Accessory spleens are frequent entities, but their infarction due to arterial stasis caused by segmental portal hypertension is extremely rare. We present this case of a 38-year-old female patient with a three-week history of abdominal pain and an abdominal CT scan revealing a 7 cm mass near the spleen and tail of pancreas with segmental portal hypertension. The patient had no hematologic disease. This mass was surgically resected, with a pathological diagnosis of an infarcted accessory spleen.

Epidermoid cyst of the spleen: case report.

Splenic cysts, very rare pathologies, are classified into parasitic and the highly uncommon, non parasitic cysts. Based on the presence or absence of an epithelial lining wall, the latters are classified into true cysts and false cysts. We present a case of a 23-year-old male who presented to our clinic with a several-month history of abdominal discomfort that was due to the compressive effect of a huge nonparasitic true splenic cyst.

Open partial nephrectomy with selective renal parenchymal control: a new reliable clamp.

We describe our experience of open partial nephrectomy with a parenchymal clamp, the Reni-Clamp, in 30 patients from January 2002 to May 2005. The mean operative and clamping time was 150 and 27 minutes, respectively, and the blood loss was 150 mL. The Reni-Clamp enabled us to perform partial nephrectomy safely in all cases of polar or external edge renal tumor.
