Thoracic endovascular aortic repair (TEVAR) has emerged as the preferred treatment for descending thoracic aortic aneurysms (TAA), but one of its major complications, type 1A endoleaks, can lead to aneurysm rupture and mortality if not managed promptly and effectively. This case report details an 87-year-old male patient who developed a type 1A endoleak following a TEVAR procedure for a large descending TAA. The patient's complex vascular anatomy, including a dominant right vertebral artery and an aneurysmal left subclavian artery, necessitated a tailored surgical approach.

Biliary diseases such as cholelithiasis, choledocholithiasis, and cholecystitis all rely on imaging modalities to help make diagnoses. In modern times, ultrasound, computer tomography, and nuclear medicine scans help precisely visualize biliary and hepatic anatomy and pathology. The predecessor of these imaging modalities was the cholecystogram.

Introduction: Diverticular disease is one of the most common gastrointestinal diseases that require hospital admission. This study aims to identify trends in prior hospital admissions for patients that ultimately require a Hartmann's procedure for complicated diverticulitis.

Methods: The Nationwide Readmissions Database for 2010-2014 was queried for all patients aged 18 years or older admitted with an ICD-9 code for colonic diverticulitis and end colostomy creation.

Dedifferentiated liposarcoma (DDL) is a rare soft tissue tumor that represents a non-lipogenic progression of well-differentiated liposarcoma (WDL). Unlike WDL, DDL has the propensity for metastasis and is associated with an increased incidence of local recurrence. For DDL of the extremities that is resectable with acceptable functional outcomes, treatment includes primary surgical resection with negative margins.

At our center, over 200 patients undergo minimally invasive repairs of inguinal hernias every year using a laparoscope and a robotic-assisted technique. In three patients who underwent a minimally invasive procedure for uncomplicated indirect inguinal hernia, the postoperative course was complicated with bleeding and required an exploratory laparotomy. Post-procedure, the patients developed tachycardia and hypotension with a drop in hemoglobin, for which the patients required surgical re-exploration in an emergent fashion.

A Spigelian hernia is a very rare hernia, making up approximately 0.1% of all abdominal wall hernias. This hernia goes through a defect in the Spigelian fascia which is the part of the transversus abdominis aponeurosis lateral to the rectus muscle, often at the level of the arcuate line, where the fascia is widest and weakest.

We would like to report an unusual case of a pericecal hernia in a 93-year-old female. The patient did not report a history of previous abdominal surgery and presented with acute abdominal pain, constipation, nausea, and vomiting. Diagnosis was made with computerized tomography and laparoscopy was performed, which was significant for loops of small bowel in the pericecal region in a defect of peritoneum.

The Grynfeltt-Lesshaft hernia is a rare posterior abdominal wall defect that allows for the herniation of retro- and intraperitoneal structures through the upper lumbar triangle. While this hernia may initially present as a small asymptomatic bulge, the defect typically enlarges over time and can become symptomatic with potentially serious complications. In order to avoid that outcome, it is advisable to electively repair Grynfeltt hernias in patients without significant contraindications to surgery.

Teratomas are bizarre neoplasms derived from embryonic tissues that are typically found only in the gonadal and sacrococcygeal regions of adults. Retroperitoneal teratomas are rare and present challenging management options. We report here the case of a histologically unusual retroperitoneal tumor detected on computed tomography during the workup of abdominal pain in a 32-year-old male.
