Arteriovenous Malformation of the Jejunum, Causing Massive Gastrointestinal Bleeding, Treated With Intraoperative Enteroscopy Guidance: A Case Report.

Arteriovenous malformations of the small intestine are an important differential in cases of occult gastrointestinal bleeding. Localization of the source of gastrointestinal bleeding can be a difficult task, especially in resource-limited settings where balloon-assisted enteroscopy or video capsule endoscopy are unavailable. We herein report the use of intraoperative enteroscopy to help localize and resect a short bowel segment containing a bleeding arteriovenous malformation of the jejunum in a 50-year-old man who presented with hematochezia and pallor leading to hemorrhagic shock. Esophagogastroduodenoscopy and colonoscopy showed no abnormalities, but a contrast-enhanced computed tomography scan of the abdomen revealed a contrast blush in the proximal jejunum. Angiography with coil embolization failed to control his symptoms, and he underwent exploratory laparotomy with intraoperative enteroscopy to try and localize the bleeding, followed by resection of the diseased segment and anastomosis of the small bowel, which led to the successful resolution of the patient's issues.

Transmesenteric hernia with closed-loop small bowel obstruction: A case report.

BACKGROUND: Transmesenteric hernia is a subtype of internal abdominal hernia (IAH) and a rare cause of small bowel obstruction in adults. Difficulty in reaching a definitive diagnosis due to non-specific clinical and imaging findings often cause life-threatening bowel ischemia. CASE REPORT: We report a case of a 37-year-old female who presented with clinical and imaging features of small bowel obstruction. She underwent an emergency laparotomy where the diagnosis of transmesenteric hernia causing closed-loop obstruction was made. The non-viable portion of the intestine was resected, anastomosis of the ileum along with the closure of the mesenteric defect was performed. DISCUSSION: IAH is the protrusion of abdominal viscera, most commonly small bowel loops through a peritoneal or mesenteric defect into the abdominal or pelvic cavity. Considered common in children, it is rare in adults and is most common after abdominal surgeries like Roux-en-Y gastric bypass surgery. Clinical features and imaging findings are non-specific causing delay in the diagnosis. CONCLUSION: A high index of suspicion is required while assessing the patient with symptoms suggestive of acute bowel obstruction as the preoperative diagnosis of a transmesenteric hernia is challenging.

Transduodenal surgical ampullectomy for intra-ampullary papillary tubular neoplasm (IAPN): A case report.

INTRODUCTION AND IMPORTANCE: Intra-ampullary papillary tubular neoplasms (IAPNs) are relatively rare kind of neoplasms occurring in the region of the papilla which exhibit significant malignant transformation. The patient was concerned about his pain and the possibility of malignancy. CASE PRESENTATION: We report a case of a 47-year-old male who presented with persistent upper abdomen pain. Following detail investigations, he was diagnosed as IAPN and managed by transduonal ampullectomy (TDA). CLINICAL DISCUSSION: The insidious onset of IAPN along with its high risk of malignancy makes it mandatory for its proper treatment. Although, endoscopic approach is advantageous for initial therapy, it has some technical difficulties. Hence TDA forms the cornerstone in the management of IAPN with good prognosis. CONCLUSION: Transduodenal ampullectomy is a safe and feasible option for IAPN. It can be the first choice of treatment in selected cases where endoscopic papillectomy is not available.

Intra-abdominal propylene suture fragment leading to complete small bowel obstruction: A case report.

INTRODUCTION: Propylene sutures are non-absorbable sterile surgical sutures, which when present intra-abdominally act as a foreign body leading to adhesion formation. Post-operative adhesions are a common cause of bowel obstruction, with complete closed loop obstruction presenting as a surgical emergency. CASE DETAILS: A 66-year-old man who had undergone a laparotomy for bowel obstruction two years back, presented to our emergency department with features of complete bowel obstruction. Midline laparotomy revealed propylene suture and intra peritoneal adhesions acting as a constricting band around the jejunum to be the cause. DISCUSSION: Adhesions are common perturbing problem after surgeries. The presence of a foreign body further incites the process of adhesion formation by causing hindrance to the fibrinolysis process. In this case, the adhesive bands acted synergistically with the encircling prolene suture material from the previous surgery in causing a complete loop obstruction. CONCLUSION: Propylene sutures used in routine surgical procedures can migrate intra-abdominally, and lead to adhesion formation. Adhesions along with the non-absorbable suture can cause complete bowel obstruction.

Birth rate and its correlation with the lunar cycle and specific atmospheric conditions.

OBJECTIVE: This study was undertaken to use the Arizona State birth certificate database for Phoenix metropolitan hospitals, in conjunction with National Weather Service records to determine whether there is a relationship between birth rate and meteorologic or lunar conditions. This study attempts to dispel or lend significance to beliefs among hospital staff that the phase of the moon and/or meteorologic conditions are related to birth rate. STUDY DESIGN: Birth records were limited to spontaneous vaginal deliveries, 37 to 40 weeks' gestation, in Phoenix, between 1995 and 2000 (n = 167,956). Daily birth counts were merged with daily surface weather statistics from the National Weather Service for Sky Harbor Airport, and records of lunar phase for the same period. RESULTS: The analyses revealed no significant correlates of birth rate. CONCLUSION: Although there exists a popular belief that the phase of the lunar cycle and weather conditions affect birth rate, no such evidence was found in this study.
