Diagnostics in a Surgeon's Pocket-The History of Telepaque and Oral Cholecystograms.

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. This involved administration of contrast media that reliably had hepatic uptake and biliary excretion without causing significant side effects followed by radiograms of the abdomen. In the 1950s, iopanoic acid, known as telepaque, was a novel oral contrast, developed and clinical trialed for the use in diagnosing biliary pathology. A small, off-white colored powder available in a pill form, telepaque was readily available, conveniently administered by physicians at the bedside and produced beautiful cholangiograms within hours of administration. This paper briefly discusses the advent, physiology, and use of this novel compound that helped surgeons for many decades.

Portal Hypertension Due to a Traumatic Arteriovenous Fistula in a Patient With a Celiac Artery Aneurysm.

This article describes a rare case of a traumatic splenic arteriovenous fistula (AVF) causing portal hypertension in a patient presenting with abdominal pain, diarrhea, and melena. A 78-year-old was admitted to the hospital with abdominal pain. The patient's history was notable for prior laparotomy and left nephrectomy for a gunshot wound. Workup demonstrated portal hypertension with a dilated splenic vein with aneurysmal changes and a saccular celiac artery aneurysm. Celiac angiogram demonstrated a communication between celiac and portal circulation. The patient underwent laparotomy with ligation of the splenic artery and resection of the celiac artery aneurysm. In conclusion, splenic AVFs are relatively rare in clinical practice. Once the diagnosis is established, operative intervention is required to avoid complications of portal hypertension. Surgical ligation has been used in this case with a successful outcome.

Under the Microscope: The Evolution of Surgical Loupes.

Fine motor movements of the surgeon's hands are limited by the resolution of the eye. Surgical loupes have allowed the profession of surgery to surpass this threshold. This is a review of the historical milestones that lead up to the development of the modern-day loupes. We explore the Greco-Roman history of the magnifying lens, its subsequent application to corrective eyewear centuries later, and the multiple ground-breaking advancements of the compound lens microscope. Moreover, we review the development of pre-modern loupes as each iteration improved through time. The aim of this historical review is to kindle an appreciation for the millennia of development that led to such instrumental modern-day technology.

Nationwide Analysis of Hospital Admissions Prior to Hartmann's Procedure for Acute Diverticulitis.

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. Patients with prior hospital admissions were identified. The primary outcome was mortality after Hartmann's procedure. Secondary outcomes were prior hospital admission and previous percutaneous drain placement. Multivariable logistic regression was performed to control for confounding factors for each outcome and results were weighted for national estimates. RESULTS: There were 90,162 patients admitted with complicated diverticulitis requiring end colostomy creation. Prior hospital admissions were found in 28.1% (n = 25,307) and 14.4% (n = 12,947) had a previous percutaneous drain placed during a prior admission. The overall mortality rate was 5.9% (n = 5314) after Hartman's procedure. The mortality rate for patients with prior hospital admissions was 8.7% (P < .001), and the mortality rate for patients with previous percutaneous drain placement was 4.3% (P < .001). After controlling for confounding factors including comorbidities, patients with prior admission had an increased risk of mortality (OR 1.48 [1.40-1.58], P < .001) and patients with previous percutaneous drain placement had a decreased risk of mortality (OR .66 [.60-.72], P < .001). CONCLUSIONS: Hospitalizations for complications of diverticulitis are a costly burden to our healthcare system. By identifying those patients at high risk for readmission and emergency surgery, perioperative outcomes may be improved.

The Evolution of Bariatric Surgery-From Sewing Lips to Constructing the Sleeve.

Bariatric surgery remains the most durable weight loss option to address morbid obesity, providing lasting reduction of debilitating chronic comorbidities. This is a review of the historical milestones that led up to the development of this surgical practice. We explore perceptions and interventions for obesity as early as the 10th century, as well as pre-modern surgical perceptions and advancements in foregut and obesity surgery. Additionally, we recount select social and surgical landmarks in the modern bariatric era. The aim of this review is to reflect on and appreciate the centuries of progress that have led to such an instrumental branch of risk reductive surgery.

Limb Salvage Resection of Massive Dedifferentiated Thigh Liposarcoma in a Patient Lost to Follow-Up.

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. Although rare due to advances in reconstructive techniques, amputation for DDL of the extremities should be considered in which appropriate tumor resection cannot be performed without adequate preservation of limb function. We present the clinical progression of a patient with a large DDL of the right thigh who was initially lost to follow-up, but ultimately underwent delayed definitive therapy with the intent for limb salvage. This case illustrates the importance of assessing neurovascular, osseous, and soft tissue involvement to properly predict and preserve limb function while achieving adequate tumor resection.

Gluteal Compartment Syndrome After Prolonged Immobilization in Drug Abusers.

Background There has been an increasing incidence of drug abuse patients presenting with rhabdomyolysis after prolonged immobilization. Our study was to assess etiology and management challenges with patients presenting with gluteal compartment syndrome after drug abuse. Methodology We did a retrospective analysis of five patients who presented with gluteal compartment syndrome secondary to drug abuse over one year. Results We had a 100% association with rhabdomyolysis and acute renal injury necessitating hemodialysis. There was a frequent association with the involvement of additional compartments like thigh and leg. Conclusion Patients with drug overdose can present with unusual compartment syndrome involvement like the gluteal compartment. Compartment syndrome is a surgical emergency and needs multidisciplinary involvement.

Major Bleed Post Minimally Invasive Surgical Repair of Inguinal Hernia.

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. The factors leading to bleeding were analyzed and are reported herein to increase awareness and prevent the occurrence of these complications during inguinal hernia surgery.

Pelvic Rectal Stercoral Perforation Resulting in Diffuse Pneumatosis.

An 83-year-old woman with oral corticosteroid use for chronic autoimmune conditions presented with abdominal pain and constipation for the previous seven days. CT of the abdomen and pelvis revealed a large fecaloma with diffuse pneumatosis involving the retroperitoneum, subcutaneous tissue, and mediastinum. An emergent exploratory laparotomy revealed perforation of the rectum below the peritoneal reflection into the retroperitoneum. An end-colostomy with Hartmann's operation was then performed intra-operatively. Despite operative treatment complicated by prolonged intubation, the patient succumbed to multiorgan failure and expired.

Delayed Presentation of Foot Compartment Syndrome.

A 30-year-old male after consuming alcohol and drugs lost consciousness and passed out in his bathroom. After 10 hours, he was found immobilized stuporous on his bathroom floor and brought by emergency service to the emergency room. He was found to have compartment syndrome of the right lower limb and underwent emergency fasciotomy of three compartments of the thigh and four compartments of the leg. The postoperative course was complicated by acute kidney injury necessitating hemodialysis. On postoperative day three from the index fasciotomy patient was found to develop foot compartment syndrome despite not having foot compartment involved in the initial presentation. In opioid abuse, patients' additional compartments can get involved during the disease process, and it is essential to identify them with regular physical examination and use of biomarkers.

Idiopathic Pneumatosis of Small Bowel and Bladder.

An 81-year-old woman presented with multiple episodes of loose bowel movements. CT scan of the abdomen and pelvis revealed pneumatosis cystoides intestinalis and asymptomatic emphysematous cystitis. The patient had an extensive workup with no obvious identified pathology to explain diffuse pneumatosis of the small bowel and bladder. Her symptoms improved with symptomatic management, empirical antibiotics, and no surgical intervention.

Fulminant Ischemic Pancolitis: A Severe Variant of Ischemic Colitis.

We present the case of a 75-year-old female with abdominal pain and a sudden change in mental status. She progressed rapidly with manifestations of acidosis without episodes of bloody bowel movements or diarrhea. The patient underwent emergent exploratory laparotomy, and a diagnosis of fulminant ischemic pancolitis was made with visual confirmation of infarcted colon from cecum to proximal rectum leading to subtotal colectomy and ileostomy. Postoperatively, the patient showed improved acidosis and mental status; unfortunately, over the subsequent days, the patient declined and was transferred to hospice and palliative care.

Incarcerated Spigelian Hernias: A Rare Cause of a High-grade Small Bowel Obstruction.

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 present the case of a 77-year-old female with no past surgical history who presented to our teaching hospital with high-grade small bowel obstruction secondary to an incarcerated Spigelian hernia. She was taken to the operating room for a laparotomy and a portion of the small bowel mesentery was found to be strangulated. The hernia was reduced, and the defect was repaired primarily. The diagnosis of a Spigelian hernia can often be difficult to diagnose on history and physical examination alone, but computed tomography (CT) imaging can be a valuable adjunct in diagnosis. Prompt surgical treatment should ensue when the diagnosis of high-grade bowel obstruction is made in a patient with imaging findings consistent with a Spigelian hernia.

Pericecal Hernia Presenting as Acute Appendicitis.

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 small bowel loops were mobilized back in the intraperitoneal location and the defect was closed to prevent further herniation. Our case is an extremely rare presentation of a rare condition, as there have only been five reported cases of pericecal hernias that required immediate surgical intervention and outlined explicit details of the surgical procedure. Pericecal hernias are unusual occurrences and occur more frequently in older women. Since the clinical signs and symptoms mimic acute appendicitis, delays in diagnosis are common. Thus, this case highlights the importance of suspecting strangulated internal hernias in patients with signs and symptoms of acute appendicitis to prevent significant morbidity and mortality.

Hepatic Artery Aneurysm in the Setting of Acute Pancreatitis and Giant Cell Arteritis.

Visceral artery aneurysms are rare with an incidence of 0.1%-0.2%. Of these, 20% are hepatic artery aneurysms (HAAs). Despite the potential of remaining asymptomatic for long periods of time, the risk of rupture for HAAs is 20%-80%. Treatment includes operative management with open or endovascular techniques. HAA in the setting of pancreatitis has been reported in two prior cases outside of the United States. However, there have been no cases describing the association of HAA and giant cell arteritis (GCA). We present a rare case of an 80-year-old male with a history of GCA who was found to have developed HAA following an episode of acute pancreatitis that was repaired surgically with an open technique. To our knowledge, the association between HAA with acute pancreatitis and GCA has not been reported before.

Grynfeltt Hernia: A Deceptive Lumbar Mass with a Lipoma-Like Presentation.

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. Due to the limited number of lumbar hernioplasties performed, there has not been a large study that definitively identifies the best repair technique. It is generally accepted that abdominal hernias such as these should be repaired by tension-free methods. Both laparoscopic and open techniques are described in modern literature with unique advantages and complications for each. We present the case of an unexpected Grynfeltt hernia diagnosed following an attempted lipoma resection. We chose to perform an open repair involving a combination of fascial approximation and dual-layer polypropylene mesh placement. The patient's recovery was uneventful and there has been no evidence of recurrence at over six months. Our goal herein is to increase awareness of upper lumbar hernias and to discuss approaches to their surgical management.

Acute abdominal pain secondary to chilaiditi syndrome.

Chilaiditi syndrome is a rare condition occurring in 0.025% to 0.28% of the population. In these patients, the colon is displaced and caught between the liver and the right hemidiaphragm. Patients' symptoms can range from asymptomatic to acute intermittent bowel obstruction. Diagnosis is best achieved with CT imaging. Identification of Chilaiditi syndrome is clinically significant as it can lead to many significant complications such as volvulus, perforation, and bowel obstruction. If the patient is symptomatic, treatment is usually conservative. Surgery is rarely indicated with indications including ischemia and failure of resolution with conservative management.

Giant primary retroperitoneal teratoma in an adult: a case report.

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. The evaluation and treatment of this condition and a review of the literature are included in this paper.
