Surgery questions

A 35-year-old woman presents to the Emergency Department with a 3-day history of worsening anal pain, accompanied by fever and chills. She reports significant discomfort, especially when sitting or having bowel movements. Her past medical history is unremarkable. On physical examination, she appears acutely uncomfortable. Vital signs include a temperature of 101.5°F (38.6°C), heart rate of 98 bpm, and blood pressure of 120/75 mmHg. Local examination of the perianal area reveals a tender, indurated, erythematous swelling in the right posterior quadrant, approximately 3 cm in diameter. There is no overt fluctuance noted on palpation, but the area is extremely painful to touch. Digital rectal examination is deferred due to severe pain. Based on her presentation and findings, what is the most likely diagnosis and the immediate definitive management strategy?

A 28-year-old woman presents to an outpatient clinic complaining of a painless lump in her left breast, which she discovered approximately 2 weeks ago. Her past medical history is notable for mild asthma, well-controlled with an as-needed inhaler. Her mother was diagnosed with breast cancer at age 65. The patient's current medication includes a combined oral contraceptive pill. On physical examination, a 1.5 cm, non-tender, mobile, rubbery, and well-circumscribed mass is palpable in the upper outer quadrant of the left breast. The overlying skin appears normal, and there is no associated nipple discharge or regional lymphadenopathy. The right breast is unremarkable. Laboratory tests performed during the visit show: White Blood Cell count 6.2 K/uL, Hemoglobin 13.8 g/dL, and Platelet count 275 K/uL. What is the most appropriate initial diagnostic approach and management strategy for this patient?

A 68-year-old female, two days post-elective laparoscopic cholecystectomy, presents to the surgical ward nurse with persistent spiking fevers up to 102.5°F (39.2°C) since the evening of her surgery. Despite consistent encouragement from nursing staff, she has been reluctant to ambulate, declines using her incentive spirometer effectively, and complains of general malaise. On examination, coarse crackles are noted over her right lower lung field with dullness to percussion. Her white blood cell count is elevated. Given her clinical presentation and lack of response to initial supportive measures, what is the most appropriate next step for confirming the diagnosis and initiating definitive therapeutic management?

A 35-year-old woman presents to the emergency department after a motor vehicle collision where her upper abdomen struck the dashboard. She complains of persistent, vague epigastric pain and has noticeable bruising over the epigastrium. Her vital signs are stable: BP 118/72 mmHg, HR 88 bpm, RR 16/min, Temp 37.0°C. Initial physical examination reveals mild epigastric tenderness without rebound or guarding, and diminished bowel sounds. An abdominal X-ray, performed as part of the trauma workup, reveals free air adjacent to the right kidney and psoas muscle. Based on these findings and her presentation, what is the most likely diagnosis, and what is the definitive initial management strategy?

A 70-year-old woman is being managed in a step-down unit following an extensive abdominal surgery for a ruptured diverticulitis 48 hours prior. She experienced a prolonged period of intraoperative hypotension requiring vasopressor support. She now complains of new-onset, diffuse abdominal cramping that has progressively localized to her left lower quadrant over the past 4 hours. Approximately 30 minutes ago, she passed a loose, dark red stool. Her medical history includes well-controlled type 2 diabetes mellitus, hypertension, and chronic kidney disease stage 3. Her current medications include insulin glargine, lisinopril, and cefepime for presumed postoperative infection. On physical examination, the patient is awake and oriented but appears uncomfortable. Her temperature is 38.5 C (101.3 F), blood pressure is 98/55 mm Hg, pulse rate is 98/min, respiration rate is 20/min, and oxygen saturation is 95% on 2 L nasal cannula. Abdominal examination reveals mild distension with soft tenderness to palpation in the left lower quadrant, but no guarding or rebound tenderness. Bowel sounds are diminished. A recent flexible sigmoidoscopy, performed due to the persistent symptoms and bloody stool, showed segmental erythema, edema, and some friable mucosa in the rectosigmoid junction extending into the descending colon. Given her clinical course and recent findings, what is the most probable diagnosis, and what is the most appropriate initial management strategy?

A 45-year-old woman presents to an outpatient gastroenterology clinic complaining of severe, constant rectal pain that began approximately 36 hours ago. She reports a long-standing history of chronic constipation, often requiring significant straining during bowel movements. She denies fever, chills, or systemic symptoms. On physical examination, perianal inspection reveals a tense, purplish-blue, exquisitely tender nodule, about 2 cm in diameter, located at the anal verge, consistent with an acute perianal mass. There is no associated discharge or surrounding cellulitis. Considering the clinical presentation and findings, what is the most likely diagnosis, and what would be the definitive management strategy?

A 30-year-old previously healthy woman presents to an outpatient gastroenterology clinic for evaluation of intermittent, painless rectal spotting noted over the past month. She denies nausea, vomiting, abdominal pain, or significant change in bowel habits. Her detailed family history is notable: her father underwent a total colectomy at age 45 due due to extensive colonic polyposis and later developed prostate carcinoma. Her paternal uncle also had colonic polyps requiring surgery in his early 40s. Additionally, her mother was diagnosed with breast carcinoma at 50 years of age, and a maternal aunt had breast carcinoma at 55 years. Physical examination is unremarkable, and rectal examination reveals no palpable masses or active bleeding. Initial laboratory studies, including a complete blood count and comprehensive metabolic panel, are within normal limits. A flexible sigmoidoscopy performed during her visit reveals hundreds of small sessile and pedunculated polyps, most measuring less than 1 cm in diameter, densely carpeting the rectosigmoid colon, making a precise count impossible. Biopsies from two representative lesions confirm benign tubular adenomas. Given her compelling family history and endoscopic findings, what is the most appropriate definitive diagnostic step and subsequent long-term management strategy to mitigate future malignancy risk, and which genetic defect is most commonly associated with this condition?

A 62-year-old male with a history of type 2 diabetes and hypertension underwent laparoscopic cholecystectomy with intraoperative cholangiogram and common bile duct exploration due to recurrent episodes of cholangitis caused by choledocholithiasis. He was discharged on postoperative day 2. On his follow-up visit to the surgical outpatient clinic 7 days after the procedure, he complains of persistent incisional pain, malaise, and a low-grade fever at home for the past 24 hours. His wife noted purulent discharge from one of the port sites. On examination, his temperature is 38.5 C (101.3F), heart rate 92 bpm, blood pressure 130/80 mmHg. The abdominal incision site around the umbilical port appears erythematous, indurated, and tender to palpation, with a small amount of cloudy drainage. What is the most likely diagnosis and the initial management strategy for this patient?

A 38-year-old woman is brought to the trauma bay after sustaining a high-velocity projectile injury to her abdomen. She reports severe abdominal pain and recalls a single impact, followed by immediate recognition of significant bleeding. Initial assessments included the placement of two large-bore peripheral intravenous lines. Her vital signs upon arrival were blood pressure 105/75 mm Hg, pulse 118/min, and respirations 28/min with an oxygen saturation of 95% on supplemental oxygen. Her head and neck are without injury, and her lung sounds are clear bilaterally. A bullet entry wound is noted in the left lower quadrant of the abdomen, with an associated exit wound in the left flank. Frank blood is actively extruding from the entry site. Her abdomen is distended, exquisitely tender to palpation, and exhibits board-like rigidity with absent bowel sounds. Rectal examination reveals good sphincter tone but gross blood on the examining finger. Distal pulses in all extremities are strong. Despite receiving a 2-liter intravenous crystalloid bolus, her blood pressure subsequently drops to 78/45 mm Hg and her pulse accelerates to 138/min. She appears pale, diaphoretic, and her mental status deteriorates to lethargy. Considering her persistent hemodynamic instability and clinical presentation, what is the most appropriate definitive diagnosis and immediate surgical management?

A 72-year-old man with a history of long-standing hypertension, 40-pack-year smoking history, hyperlipidemia, and a known 5.5 cm abdominal aortic aneurysm noted incidentally 6 months ago, presents to the emergency department. He reports sudden-onset excruciating tearing abdominal pain radiating to his back that began 30 minutes prior. On examination, he is pale, diaphoretic, and hypotensive with a blood pressure of 78/50 mm Hg, a pulse of 135/min, and a respiratory rate of 30/min. His abdomen is distended, diffusely tender with guarding, and a palpable, pulsatile abdominal mass is noted just above the umbilicus. Flank ecchymosis is also observed. Peripheral pulses are diminished. Considering his clinical presentation and a known history, what is the most appropriate immediate diagnostic and management step for this patient?
