Disposable Gastrointestinal Scopes: A Systematic Review.

OBJECTIVE: Endoscopes are an essential tool in the diagnosis, screening, and treatment of gastrointestinal diseases. In 2019, the Food and Drug Administration issued a news release, recommending that duodenoscope manufacturers and health care facilities phase out fully reusable duodenoscopes with fixed endcaps in lieu of duodenoscopes that are either fully disposable or those that contain disposable endcaps. With this study, we systematically reviewed the published literature on single-use disposable gastrointestinal scopes to describe the current state of the literature and provide summary recommendations on the role of disposable gastrointestinal endoscopes. MATERIALS AND METHODS: For our inclusion criteria, we searched for studies that were published in the year 2015 and afterward. We performed a literature search in PubMed using the keywords, "disposable," "reusable," "choledochoscope," "colonoscope," "duodenoscope," "esophagoscope," "gastroscope," and "sigmoidoscope." After our review, we identified our final article set, including 13 articles relating to disposable scopes, published from 2015 to 2023. RESULTS: In this review, we show 13 articles discussing the infection rate, functionality, safety, and affordability of disposable gastrointestinal scopes in comparison to reusable gastrointestinal scopes. Of the 3 articles that discussed infection rates (by Forbes and colleagues, Ridtitid and colleagues, and Ofosu and colleagues), each demonstrated a decreased risk of infection in disposable gastrointestinal scopes. Functionality was another common theme among these articles. Six articles (by Muthusamy and colleagues, Bang and colleagues, Lisotti and colleagues, Ross and colleagues, Kang and colleagues, and Forbes and colleagues) demonstrated comparable functionality of disposable scopes to reusable scopes. The most reported functionality issue in disposable scopes was decreased camera resolution. Disposable scopes also showed comparable safety profiles compared with reusable scopes. Six articles (by Kalipershad and colleagues, Muthusamy and colleagues, Bang and colleagues, Lisotti and colleagues, Luo and colleagues, and Huynh and colleagues) showed comparable rates of AEs, whereas 1 article (by Ofosu and colleagues) demonstrated increased rates of AEs with disposable scopes. Lastly, a cost analysis was looked at in 3 of the articles. Two articles (by Larsen et al and Ross and colleagues) remarked that further research is needed to understand the cost of disposable scopes, whereas 1 article (by Kang and colleagues) showed a favorable cost analysis. CONCLUSIONS: After a review of the literature published since the 2015 Food and Drug Administration safety communication, disposable scopes have been shown to be effective in decreasing infection risks while maintaining similar safety profiles to conventional reusable scopes. However, more research is required to compare disposable and reusable scopes in terms of functionality and cost-effectiveness.

Intravascular large B-cell lymphoma masquerading as stroke successfully treated with R-Hyper-CVAD.

Intravascular large B cell lymphoma (IVLBCL) is exceedingly rare and difficult to diagnose. We describe a case of IVLBCL in a 56-year-old male which was identified after recurrent strokes. Right partial nephrectomy was then performed which demonstrated renal oncocytoma and IVLBCL. Chemotherapy was initiated with standard R-Hyper-CVAD which included intrathecal methotrexate and cytarabine. R-CHOP is largely considered the treatment of choice in IVLBCL, however low doses of chemotherapy in this regimen do not cross the blood brain barrier like in R-Hyper-CVAD. The patient achieved complete remission after completion of treatment and has remained in remission for 5 years after diagnosis.

Surgical Marking Pen Contamination: Writing a Postoperative Infection Into Your Preoperative Plan.

Introduction Preoperative marking is an essential safety practice to prevent "never" events, including wrong site surgery. Moreover, the Joint Commission regulations of the Universal Protocol require that patients be marked to indicate the operative site. Marking typically occurs with a pen or marker, which may be disposable or reusable. Previous studies have demonstrated that methicillin-resistant Staphylococcus aureus (MRSA) can survive in the dark, moist, capped environment of the marking pen and thus could plausibly be a nidus for transmission from patient to patient. The Joint Commission has established no increased risk of postoperative infection with these markings. With this study, we aimed to determine the colonization of surgical marking pens in the plastic surgery population. Methods Two marking pens from five different attending plastic surgeons at a single institution were cultured in standard fashion for aerobic and anaerobic growth. All pens were used repeatedly in office settings for performing patient markings. Those same ten marking pens were then used to mark incision sites on mock patients. Standard povidone-iodine prepping was then performed in a paint-only fashion over the skin markings, and cultures were again taken. A control group consisted of cultures from five sterile pens from the operating room. Each sterile pen was opened, uncapped, and then swabbed. All twenty-five cultures were analyzed in the hospital laboratory in a blinded fashion. Results The five control pens revealed no bacterial growth. Of the 10 direct pen cultures, two samples grew coagulase-negative staphylococci and one culture contained Pseudomonas aeruginosa. The 10-patient marked and prepped specimens showed eight negative cultures and two with coagulase-negative staphylococci. Although Pseudomonas was detected on standard pen culture, no pseudomonal growth was present in any of the samples after patient marking and prepping with povidone-iodine. Conclusions Our findings reaffirm that marking pens may be vehicles for bacterial transmission and expand upon previous studies by describing the presence of bacterial colonization on marking pens even after surgical site preparation with povidone-iodine.

Delayed Thoracodorsal Artery Perforator Free Flap for Calcaneal Degloving Injury Reconstruction.

The thoracodorsal artery perforator (TDAP) flap has a long vascular pedicle that is ideal for lower extremity reconstruction, but it generally relies on the presence of a dominant septocutaneous perforator vessel. Surgical delay optimizes flap survival by creating relative ischemia to augment perforator vessels. In this report, we describe the use of a delayed free TDAP flap in the setting of an absent dominant perforator vessel for the reconstruction of a calcaneal degloving injury. A 22-year-old actively smoking patient with a body mass index of 33.5 presented with a nonhealing left heel wound with overlying necrotic changes after traumatic degloving injury. The entire weight-bearing portion of the calcaneal fat pad and the flanking regions were debrided. The TDAP flap was elevated, revealing three small thoracodorsal artery perforators. Given that a dominant perforator was absent, the flap was surgically delayed. Free-tissue transfer occurred 8 days later. This operation was conducted entirely in left lateral decubitus with simultaneous wound preparation and flap harvest. The flap was elevated on two perforators to elongate the pedicle's length and inset to cover exposed calcaneus and pad the heel. Six months postoperatively, the patient is doing well without flap compromise or ulceration. The TDAP flap is a versatile microsurgical tool, and surgical delay extends the utility of this flap when a dominant septocutaneous perforator is unavailable. Recipient site debridement may occur simultaneously with the TDAP delay procedure. Importantly, only one position is required for flap elevation, microsurgical anastomosis, and insetting, thus obviating intraoperative repositioning.

Primary Cutaneous Secretory Carcinoma: A Case Report and Literature Review.

Cutaneous secretory carcinomas (CSCs) are primary neoplasms of the skin that have been just recently described in the literature through case reports and series. In this case, a cutaneous lesion was found on the left temporal region of an 83-year-old male. He was referred to plastic surgery for complete excision, with negative margins confirmed by pathology. Histology, immunostaining, and genetic testing showed characteristics confirming the diagnosis of CSC and were supported by the information present in the current literature. Our patient showed no evidence of nodal disease or recurrence during regular follow-ups. Given the rarity of CSCs, we aim to present our experience regarding the diagnosis, pathological analysis, and management of our patient as well as summarize the present literature to further open avenues of research.

A fully stapled technique for gastrojejunal anastomosis creation in robotic Roux-en-Y gastric bypass.

PURPOSE: The purpose of this paper is to showcase a fully stapled approach to creating a gastrojejunostomy during a robot-assisted Roux-en-Y gastric bypass. METHODS: We utilize two robotic 12-mm ports, two robotic 8-mm ports, and one 8-mm assistant port. The tools used are a fenestrated bipolar forceps, vessel sealer, cadiere grasper, needle driver, and a robotic stapler. After the partial gastrectomy, the roux limb is brought up to the gastric pouch where monopolar scissors are used to create a gastrotomy and enterotomy. The gastrotomy is made just above the staple line of the gastric pouch. The enterotomy is created 2 cm distal to the roux limb's staple line. The stapler is inserted into both the gastrotomy and enterotomy to create the common channel. A 2-0 vicryl suture is used to place four interrupted sutures across the remaining enterotomy in full thickness bites. An endoscope or Visigi bougie is advanced across the anastomosis into the roux limb before the final suture. The tails of the most lateral and medial sutures are grasped and lifted towards the abdominal wall. The stapler is advanced over the approximated enterostomy while holding tension with the suture tails. The stapler is fired transversely across the suture line to seal the gastrojejunostomy. The staple line may be oversewn with silk sutures. A leak test is performed prior to completing the reconstruction with the jejunojejunostomy. CONCLUSIONS: A fully stapled technique of anastomosis creation may reduce operative time, standardizes the process for reproducibility, and increases consistency across operators and patients.

Providencia rettgeri Infection Compromising Post-Burn Recovery: A Lesson in the Importance of Follow-Up Care.

Early burn excision and skin grafting have been essential to improving patient outcomes following a burn injury. However, there remain significant barriers to recovery for burn patients, especially in the post-discharge period, as follow-up care is essential to the timely identification of complications. While the infection is a common complication of a post-burn wound, Providencia rettgeri is an uncommon bacterial pathogen that rarely causes wound infections. Although P. rettgeri has been infrequently reported as a cause of wound infections, it is a pathogen with growing clinical significance due to innate and acquired mechanisms of antimicrobial resistance that may complicate patient treatment. While our report describes the clinical outcome of a patient with a wound infection with Providencia rettgeri, it also represents a case that underscores the importance of social determinants of health in the care of burn patients. This is a case report of an elderly male who sustained burns to his bilateral arms and back and was subsequently readmitted to our burn unit for graft loss associated with a Providencia rettgeri wound infection. His readmission required multiple operations to resect necrotic tissue and nonviable graft due to delayed wound healing and incomplete graft take. Inadequate access to transportation led to significantly delayed follow-up for this patient.

A Severe Case of Odontogenic Infection and Necrotizing Fasciitis of the Anterior Chest Wall and Neck.

Necrotizing fasciitis is a life-threatening infection that can be rapidly fatal. Early identification and emergent surgical management are essential to minimize morbidity and mortality. This case report describes a 25-year-old male who presented to the emergency department with a three-day history of worsening left lower dental infection and new-onset neck pain and swelling. He received broad-spectrum antibiotics and intravenous fluid resuscitation and underwent computed tomography of the neck and chest. Following intensive care unit admission, he underwent tooth extraction where intraoperative evaluation revealed subcutaneous crepitus. Immediate debridement was performed, revealing copious foul-smelling purulent discharge and necrotic tissue extending over the anterior chest wall and neck. During his hospital course, he underwent multiple debridements to manage the expanding infection. The final tissue defect was substantial, with deep dissection to muscle extending over the entire anterior surface of the rib cage to just inferior to the clavicles. This significant tissue defect was managed with skin grafts, and he was discharged home in stable condition. The patient is doing well almost a year after discharge. The key to our patient's survival was the early identification and debridement of the affected tissue. Our study reinforces the tenants of wound care and aggressive management required to bolster patient odds of survival in the setting of necrotizing fasciitis and underscores the importance of maintaining vigilance in patients presenting with dental infections. This study is unique in that our patient was young, with a past medical history significant for polydrug use, and the area of debridement was substantial.

Trastuzumab Associated With Recurrent Severe Thrombocytopenia and Successful Use of Pertuzumab Monotherapy.

Trastuzumab is a mainstay chemotherapeutic agent used in the treatment of human epidermal growth factor receptor 2 (HER2)/neu-positive breast cancer that, though generally well-tolerated, is classically associated with side effects like cardiotoxicity. Cytopenias can be seen but are generally secondary to other chemotherapeutic agents used in conjunction with trastuzumab. Herein, we present a case of recurrent severe thrombocytopenia following trastuzumab use that resolved following discontinuation. Our patient then finished a year of maintenance therapy with pertuzumab alone and is still in remission four years later. This is the eleventh report of this severe adverse effect described in the literature. This report contributes to the body of work describing this severe side effect by illustrating a clear temporal relationship between trastuzumab and severe thrombocytopenia, while also providing an alternate treatment option with chemotherapy and pertuzumab monotherapy. Given that pertuzumab is typically only used in addition to trastuzumab, evidence of its successful independent use is of clinical value to patients who may not be able to tolerate trastuzumab.

A Severe Case of Siliconoma-induced Hypercalcemia due to Illicit Gluteal Silicone Injections.

Siliconoma-induced hypercalcemia is a rare complication of siliconoma, occurring secondary to a foreign body granulomatous process induced by the introduction of silicone into soft tissue. This is a case report of a woman presenting with sequelae of illicit silicone injections performed in an unknown woman's basement in Florida 20 years before presentation. A 39-year-old woman presented with a 2-month history of 20-pound weight loss, malaise, and intractable vomiting with a remote history of unregulated cosmetic injections to the bilateral gluteal and thigh regions. Her laboratory studies were consistent with severe hypercalcemia secondary to a foreign body granulomatous process. Initially, she was medically managed, with mild improvements in her symptomatic hypercalcemia and later underwent palliative debridement with siliconoma removal. Postoperatively, her course was complicated by delayed wound healing and graft failure, but the surgical defect was later closed successfully with split-thickness skin grafting after months of wound care. Although the procedure was not intended to treat her hypercalcemia, there were significant improvements in serum and ionized calcium in the months following her procedure. Severe hypercalcemia in the context of previous unregulated cosmetic injections or possible silicone implant rupture should prompt consideration of siliconoma-induced hypercalcemia as the underlying etiology. In addition to the established utility of IV fluids, bisphosphonates, and glucocorticoids, there may also be a role for surgical intervention in the management of this unique patient population's hypercalcemia.

The Relationship between Body Mass Index and Operative Complications in Patients undergoing Immediate Postpartum Tubal Ligation.

OBJECTIVE: The objective of this study is to examine the relationship between body mass index (BMI) and complications for patients undergoing postpartum permanent contraception. STUDY DESIGN: Retrospective cohort study of patients aged 18 or older who had a vaginal delivery at an academic hospital between 2011 and 2016 and underwent a postpartum tubal ligation during the delivery admission. There were three comparative groups: nonobese (BMI ≤ 29 kg/m2), obese (BMI 30-39 kg/m2), and morbidly obese BMI (≥40 kg/m2). The outcome of interest was composite operative complications which included any occurrence of an intraoperative, postoperative, or anesthesia complication. RESULTS: A total of 921 patients were included for analysis. Average operative time was statistically longer for patients in the morbidly obese group (33 minutes) vs. the nonobese (25 minutes) and obese (29 minutes) groups (p < 0.0001). Composite complications were greater for the obese groups, but not statistically significant (5.1 vs. 6 vs. 16%, p = 0.06). Wound complications were significantly greater for the obese groups (0.8 vs. 1.5 vs. 5.5%, p = 0.01). A logistic regression model demonstrated that only operative time was predictive of operative complications. CONCLUSION: Overall complications of postpartum tubal complications are low; however, our study did demonstrate significantly longer operative time and wound complications for patients with obesity. The findings of our study indicate that postpartum permanent contraception can remain as an option for these patients. Further studies may help identify the best practices to decrease operative time and subsequent wound complications. This study contributes to the limited data regarding obesity and postpartum permanent contraception. We found increased operative time and wound complications for obese patients. Additional studies may identity best practices to decrease these complications. Given our findings of overall low operative complications, postpartum permanent contraception can remain an option for obese patients.

Acute angle closure glaucoma precipitated by homeopathic eyedrops containing Atropa belladonna.

Acute angle closure glaucoma is a sight-threatening condition that may lead to blindness. This is a case report of a woman who presented to the emergency department (ED) with acute angle closure glaucoma following use of an over-the-counter (OTC) homeopathic eye drop containing atropa belladonna (deadly nightshade). A 55-year-old woman presented to the ED with a 5-day history of left eye redness, swelling, tearing, and foreign-body sensation that had acutely worsened in the last two days. Her exam revealed mild left conjunctival injection with watery tearing and a hazy appearance of her left cornea. Fluorescein staining was negative, while tonometry revealed elevated intraocular pressure on the left, suggestive of acute angle closure glaucoma. She was urgently referred to ophthalmology. The etiology of the acute angle closure glaucoma was initially unclear however, with additional prompting, she revealed that two days prior she had started using homeopathic OTC eye drops. Inspection of the eyedrop's ingredients revealed that atropa belladonna was the primary ingredient and likely precipitated her isolated episode of acute angle closure glaucoma. A high level of clinical suspicion and focused ophthalmic exam including tonometry is essential to identify acute angle closure glaucoma in the ED. We present a case report of acute angle closure glaucoma associated with the use of homeopathic belladonna-containing eyedrops. Our report reinforces the necessity to perform thorough medication and supplement history given the prevalence of physiologically active substances available in OTC medications.
