Type IV Mirizzi Syndrome: Brief Report and Review of Management Options.

Mirizzi syndrome is a rare complication of chronic calculous cholecystitis. Preoperative diagnosis is challenging due to the absence of pathognomonic signs and symptoms and low sensitivity rates of imaging tests. Historically, laparotomy has been the preferred choice of surgical management. Endoscopic and laparoscopic approaches have been increasingly described as diagnostic and therapeutic options for Mirizzi type I and II, but data is limited regarding the management of more complex cases. We describe a staged endoscopic and laparoscopic approach for the management of type IV Mirizzi syndrome and review the management options.

Laparoscopic sleeve gastrectomy for giant gastric lipoma in morbid obese patient.

ANTECEDENTES: Los lipomas gástricos corresponden al 5% de los lipomas gastrointestinales. Muchos de ellos son solitarios, pequeños y asintomáticos, pero también pueden ocasionar síntomas obstructivos y sangrados. El tratamiento estándar es quirúrgico. CASO CLÍNICO: Mujer de 50 años con antecedente de obesidad mórbida, índice de masa corporal de 47.4 kg/m2, que se presenta con síntomas de epigastralgia y anemia. Se diagnostica un lipoma gástrico de 6.3 cm mediante tomografía y se confirma por biopsia endoscópica. DISCUSIÓN: La paciente fue exitosamente tratada a través de gastrectomía laparoscópica en manga. CONCLUSIÓN: La gastrectomía laparoscópica en manga es el procedimiento de elección para el tratamiento de los lipomas gástricos gigantes en los pacientes con obesidad mórbida cuando la anatomía lo permite. BACKGROUND: Gastric lipomas account for 5% of all gastrointestinal lipomas. Most of them are solitary, small and asymptomatic, however, they can cause severe symptoms such as obstruction, bleeding and intussusception. The standard treatment is surgical resection. CASE REPORT: 50 years old female with history of morbid obesity with a body mass index (BMI) of 47.4 Kg/m2, who presented with symptoms of epigastric pain and anemia. CT scan of the abdomen revealed a 6.3 cm gastric lipoma, confirmed by endoscopic biopsy. DISCUSSION: Laparoscopic sleeve gastrectomy is the procedure of choice for the excision of giant gastric lipomas in the morbidly obese, when anatomically feasible.

Blunt Traumatic Occlusion of the Common Iliac Artery Repaired With Segmental Excision and Internal Iliac Artery Patch Angioplasty.

Common iliac artery (CIA) occlusion as a result of blunt trauma is rare and seldom reported. This has been associated with pelvic fractures and other great vessel lesions. Management options include endovascular covered stent placement, open anatomic repair with autogenous conduit, or open extra-anatomic repair with prosthetic material. We report the case of a middle-aged male with a right CIA injury secondary to blunt trauma who underwent a successful repair using an internal iliac artery patch for injury to a 2 cm segment of CIA with peritoneal contamination. There is no definitively superior method to address CIA injuries in this setting reported in the literature. The use of the internal iliac artery as a patch can be regarded as an additional safe repair option when an autogenous repair is required for a large defect in the CIA as this can enable mobilization of the vessel for primary repair and offer a source for an autogenous patch.

Diffuse hepatic epithelioid hemangioendothelioma developed in a patient with hepatitis C cirrhosis.

Hepatic epithelioid hemangioendothelioma (HEHE) is an infrequent vascular tumor of endothelial origin that primarily occurs in women in the mid-fifth decade of life without underlying chronic liver disease or cirrhosis. Liver transplant should be the first-line of therapy in patients with large or diffuse unresectable tumors even in the presence of metastatic disease due to the favorable long-term outcome. We report the case of a 48-year-old female who complained of abdominal pain and weight loss. She has a history of cirrhosis secondary to chronic hepatitis C (HCV) and was treated with interferon and ribavirin with sustained virological response. Her work-up revealed multiple confluent infiltrating bilobar liver masses diagnosed as HEHE. She underwent a successful liver transplant without evidence of recurrent HCV infection. She developed cervical spine (C4-C6) HEHE metastases 4 years after transplant. She underwent surgical resection and local radiotherapy after resection with good clinical response. To the best of our knowledge, this is the first report of HEHE that developed in a patient with HCV cirrhosis successfully treated with antiviral therapy before transplant and liver transplant with good allograft function without evidence of recurrent liver tumor or HCV infection but developed metastases to the cervical spine 4 years after transplant.

Outcomes in the management of appendicitis and cholecystitis in the setting of a new acute care surgery service model: impact on timing and cost.

BACKGROUND: The acute care surgery model is a novel notion in the provision of emergency general surgery. To date, several studies have analyzed the effects on patient health outcomes and timeliness of care for nontrauma patients within the scope of acute general surgery and emergencies, but none have assessed the cost benefits of this model. STUDY DESIGN: A retrospective analysis of patients undergoing appendectomy or cholecystectomy in the setting of acute abdomen was performed to compare data from 2 cohorts, the traditional model from July 2009 to June 2010 and the acute care surgery model from July 2010 to June 2011. Categorical variables and comparison means were examined using chi-square and independent 2-tailed sample t-tests. RESULTS: One hundred and seventy-five patients underwent appendectomy and 113 underwent cholecystectomy. The traditional model team staffed 82 appendectomies and 51 cholecystectomies, and the acute care surgery team staffed 93 and 62, respectively. In the appendectomy group, there was a statistically significant mean reduction of time to surgical evaluation (2.19 hours; p < 0.001) and time to the operating room (5.38 hours, p = 0.006), there were 7 fewer patients with complications (p = 0.06) and a reduced length of stay (1 day, p = 0.002) for the acute care surgery cohort. Similar statistically significant differences were observed in the cholecystectomy group in the acute care surgery cohort: surgical evaluation difference = 5.84 hours (p = 0.03), time to operating room difference = 25.37 hours (p = 0.002), 8 fewer patients with complications (p = 0.01), and length of stay difference was 2 days (p = 0.03) compared with the traditional model cohort. CONCLUSIONS: The newly implemented acute care surgery model in our institution accomplished earlier treatment and shorter length of stay for the 2 most common causes of acute abdomen in our setting. Overall, the new model translated to better outcomes for patients and savings per case for the hospital.
