Rare Case of Lower Gastrointestinal Bleeding Secondary to Miliary Tuberculosis in the United States.

Tuberculosis (TB) remains a significant global health challenge. Miliary TB is a rare manifestation of TB that involves systemic lymphohematogenous dissemination of infection and presents diagnostic challenges due to its often asymptomatic or non-specific nature. This case report documents a rare occurrence of gastrointestinal (GI) bleeding secondary to miliary TB without pulmonary symptoms in an 81-year-old Filipino-American male living in the United States. Extensive imaging studies revealed a mass in the right colon with multiple bleeding vessels draped around it; it was not amendable to treatment with embolization and required right hemicolectomy with end ileostomy. The pathology report of the excised mass demonstrated miliary TB with necrotizing granulomas and granulomatous lymphadenopathy involving 23 lymph nodes. The patient was started on anti-tuberculosis medical management; however, the patient remained clinically unstable and expired on postoperative day 39. This case highlights the importance of the heightened clinical awareness required during times of globalization and in regions with dense immigrant populations. We aim to delineate the clinical understanding of gastrointestinal TB (GITB) and review possible indications for surgical management. We aim to help reduce diagnostic delay, therefore improving patient outcomes and limiting the spread of disease.

Case Report: Robotic-Assisted Minimally Invasive Repair of a Direct Sliding Left Inguinal Hernia Containing Bladder and Colon.

A direct sliding inguinal hernia descends through the superficial inguinal ring and encroaches on nearby organ structures, such as the bladder. This type of hernia is rare with a 2-5% incidence and occurs due to a weakness within the lower abdominal wall, usually associated with advancing age, that permits the distal colon to descend into the inguinal canal. Direct sliding inguinal hernias are a rare subset of inguinal hernias that require meticulous dissection due to their incorporation of nearby organs such as the bladder or colon. Few cases report repair of these hernias laparoscopically; however, the use of a hybrid laparoscopic/open approach has not been extensively documented and it may be beneficial to explore the use of this approach in inguinal hernia repair.  We present a case of a robotic-assisted minimally invasive repair of a direct sliding inguinal hernia in an 85-year-old male. He initially presented to the emergency department with left-sided groin pain and imaging revealed he had a direct sliding inguinal hernia that incorporated the bladder wall. He was admitted to surgery for a robotic-assisted minimally invasive inguinal hernia repair with mesh. During the surgery, after seeing the extent at which the hernia sac incorporated the bladder wall, the procedure was converted to an open approach to perform the remainder of the reduction; however the robot was reintroduced for mesh placement. Post-operatively, the patient experienced mild incisional abdominal pain with return of bowel function on day four and was discharged that same day.
