Small bowel ischemia secondary to gastric pacemaker wires-a case report.

Gastric stimulator has been used as a surgical option for patients with gastroparesis refractory to medical management. Only one previous report of small bowel gangrene secondary to gastric pacemaker wires has been reported in the literature. Our patient was a 38-year-old woman with a history of systemic lupus erythematosus and history of total colectomy who underwent an uneventful open gastric pacemaker placement for idiopathic gastroparesis. Four months after the initial placement of the pacemaker, she presented to the emergency department with acute abdominal pain and was found to have gangrene of 140 cm of small bowel secondary to looping of gastric pacemaker wires around small bowel mesentery. She underwent uneventful small bowel resection and anastomosis with an ileorectal anastomosis. This case highlights the need for a high index of suspicion for this catastrophic complication in patients with gastric pacemakers.

Case Report of Surgical Management of Duodenal Perforation Secondary to Stent in a Patient With Gastric Outlet Obstruction Due to a Rare Neuroendocrine Adenocarcinoma of Duodenum.

Neuroendocrine adenocarcinomas of the duodenum comprise a rare subset of neuroendocrine tumors and commonly present with symptoms of gastric outlet obstruction (GOO). Most of the time, patients are recommended a GI bypass in the setting of metastatic disease. In a small subset of patients who prefer a non-operative approach or are poor surgical candidates, duodenal stenting can often accomplish similar results as surgery. However, duodenal stenting is associated with numerous complications, including duodenal stent migration and, less commonly, duodenal perforation. We present a case where duodenal stenting resulted in a perforation of the second portion of the duodenum that ultimately required a definitive pancreaticoduodenectomy.

Surgical Management of Gallstone Ileus: A Clinical Case Report.

A 74-year-old female with a past medical history of hypertension, osteoarthritis, osteoporosis, bladder suspension, and right hip surgery presented with a one-day history of cramping abdominal pain, intermittent vomiting, and obstipation. Bowel obstruction was confirmed with imaging, and the decision was made to proceed to the operating room for an exploratory laparotomy. During the procedure, a gallstone was found in the terminal ileum and was removed.

Sternal Tumor Resection and Reconstruction Using Iliac Crest Autograft.

Primary malignant tumors of the sternum are rare among bone tumors. Even with radical resection, the survival rate for sternal tumors remains low. Resection often results in significant bone defects in the chest wall, and reconstruction must provide adequate protection for pulmonary and respiratory structures. Flexible materials have historically been used for sternal reconstructions following failed sternotomies in cardiac surgery. Although these have had some success, they fail to provide adequate support for patients undergoing reconstruction secondary to tumor resection, who are otherwise healthy and active. Although rigid materials offer greater protection, they frequently cause chronic pain and respiratory complications. More recently, bone grafts have been used to reconstruct sternal defects, and the limited published reports are promising. METHODS: We present the case of a patient diagnosed with an extramedullary solitary bone plasmacytoma who underwent a sternal resection and reconstruction with an autogenous bone graft taken from the iliac crest and secured in place with 5 plates (3 sternal and 2 mandibular). RESULTS: At 9-month follow-up, bone marrow biopsy showed no evidence of multiple myeloma. X-ray, computed tomography, and Pulmonary Function Test (PFT) scans confirmed graft stability, and the patient has returned to normal activities. CONCLUSIONS: Sternal resection and reconstruction is an effective method for treating extramedullary solitary plasmacytoma when radiation is ineffective. In cases of significant segmental defects, iliac crest bone graft may be a viable option for repairing sternal defects following tumor resection.

Rectus Sheath Hematoma: A Rare Surgical Emergency.

A rectus sheath hematoma (RSH) is a rare medical condition that consists of blood accumulating in the rectus abdominis muscle sheath. RSH is most frequently due to a hemorrhage from the superior or inferior epigastric artery. RSH has many specific risk factors, such as anticoagulant use. As the use of anticoagulants increases, the incidence of RSH has also increased. This condition can present with the infrequent complication of abdominal compartment syndrome (ACS), which can require surgical decompression of the abdomen to avoid high morbidity and mortality. We present the case of a 79-year-old male who, after receiving anticoagulants, developed a right-sided RSH which progressed to ACS. The patient was transferred to our care for community-acquired pneumonia, pneumothorax, and increasing respiratory support. He was admitted to the medical intensive care unit (MICU), was placed on a nasal cannula, and given vancomycin and Zosyn for pneumonia. After two days, the patient was switched to enoxaparin for anticoagulation. After three days, the patient's pneumothorax had resolved. At this time, the patient reported swelling in his right lower quadrant (RLQ) with mild pain, nausea, vomiting, and difficulty voiding completely. The physical examination confirmed RLQ swelling, and a kidney, ureter, and bladder (KUB) x-ray and ultrasound were ordered. A CT with and without contrast was also obtained which showed a large right rectus sheath hematoma extension into preperitoneal space and a small amount of intraperitoneal fluid along the right paracolic gutter. Soon after, the patient became lightheaded and fell after using the restroom. Vitals at the time were a blood pressure of 79/56, heart rate (HR) of 127, and oxygen saturation of 88% with his hemoglobin dropping from 11.4 g/dL earlier that morning to 8.4 g/dL. The patient's care was transferred to our surgical team in the surgical intensive care unit (SICU). He received an arterial line, two doses of protamine, 1-liter of crystalloids, and two units of packed red blood cells (PRBC). The patient's vitals normalized. Interventional radiology (IR) was consulted but they requested the coagulopathy be corrected before any intervention. Reversal of his Lovenox® was thromboelastographic (TEG)-guided and included platelets, cryoprecipitate, and prothrombin complex concentrate/fresh frozen plasma (PCC/FFP), in addition to more PRBCs. During these interventions, the patient acutely decompensated with hypotension, difficulty breathing, and expansion of his hematoma. A bladder pressure in the 30s was obtained, causing him to be sent to the operating room (OR) for decompression, extraperitoneal packing, and the wound was temporarily closed. The patient returned and IR was able to embolize the right inferior epigastric artery. The patient was taken to the OR again for exploration, removal of packing, and closure. RSH is a rare complication that can occur due to trauma, coagulopathy, obesity, and muscle strains during a pregnancy. Larger hematomas tend to occur below the arcuate line because there is an absence of the posterior rectus sheath which enables the hematomas to spread. An RSH can be treated with conservative measures, but for patients who continue to bleed, more aggressive measures should be taken to avoid life-threatening complications, such as ACS.
