    Abstract Arcuate line hernias are a rare type of hernia with limited publications regarding their successful repair. The arcuate line is the inferior limit of the posterior leaf of the rectus sheath. An arcuate line hernia is a type of intraparietal hernia, meaning it is not a truly complete fascial defect of the abdominal and, therefore, may present with atypical symptoms. Although published data on arcuate line hernia repairs are limited to a handful of case reports and one literature review, reports regarding robotic repair are exceptionally rare. This case report is the second documented robotic approach to arcuate line hernias known to these authors.

    Abstract Gastric bypass has grown in popularity in recent years due to its high efficacy in achieving long-term weight loss in patients with morbid obesity. Gastric bypass has been described to further exacerbate baseline nutritional deficiencies due to reduced gastric capacity and malabsorption. In rare cases, when protein deficiency is severe, Kwashiorkor disease may arise. The incidence of Kwashiorkor specifically following gastric bypass is rare, with an incidence of 4.7%. We report a case of a female patient who underwent a gastric bypass and subsequently developed Kwashiorkor. Physicians' suspicion of index for Kwashiorkor should be high for patients presenting with signs or symptoms of severe malnutrition following weight-loss procedures.

    Abstract Post-cholecystectomy syndrome (PCS) is a well-documented complication of incomplete cholecystectomy. The etiology is often post-surgical chronic inflammation from unresolved cholelithiasis, which is secondary to anatomical abnormalities, including a retained gallbladder or a large cystic duct remnant (CDR). An exceedingly rare consequence is retained gallstone fistulization into the gastrointestinal tract. We present a case of a 70-year-old female with multiple comorbidities 4 years status-post incomplete cholecystectomy, who developed PCS with cholecystoduodenal fistula secondary to retained gallstone in the remnant gallbladder, with CDR involvement, treated via robotic-assisted surgery. Reoperation in PCS has been traditionally performed via laparoscopic approach with recent advances made in robotic-assisted surgery. However, we report the first documented case of PCS complicated by bilioenteric fistula repaired with robotic-assisted surgery. This highlights the value of robotic-assisted surgery in complicated cases, where one must contend with post-surgical anatomic abnormalities and visualization difficulties. Subsequent investigation is necessary to objectively quantify the safety and reproducibility of our approach.

    Abstract Despite well-established clinical guidelines and use of radiologic imaging for diagnosis, challenges are faced when accurate decisions must be made within seconds. Patients with life-threatening injuries represent 10-15% of all hospitalized trauma patients. In fact, 20% of abdominal injuries will require surgical intervention. In abdominal trauma, it is important to distinguish the difference between surgical intervention, which includes damage control procedures and definitive treatment. The main objective of damage control surgery is to control the bleeding, reduce the contamination and delay additional surgical stress at a time of physiological vulnerability of the patient, along with abdominal containment, visceral protection and avoiding aponeurotic retraction in situations where primary abdominal closure is not possible. However, this technique has high morbidity and comes with a myriad of complications, including development of catastrophic abdomen and formation of enterocutaneous fistulas.

    Abstract Prone ventilation refers to the delivery of mechanical ventilation with the patient lying in the prone position. The improvement of oxygenation during prone ventilation is multifactorial, but occurs mainly by reducing lung compression and improving lung perfusion. CT imaging modeling data demonstrated that the asymmetry of lung shape leads to a greater induced pleural pressure gravity gradient when supine as compared to prone positioning. Although proning is indicated in patients with severe ARDS who are not responding to other ventilator modalities, this technique has moved away from a salvage therapy for refractory hypoxemia to an upfront lung-protective strategy intended to improve survival in severe ARDS, especially due to the current COVID-19 pandemic. In view of different roles, we surgeons had to take during the COVID-19 pandemic, it is of importance to learn how to implement this therapeutic measure, especially in a surgical critical care unit setting. As such, this article aims to review the physiological principles and effects of the prone ventilation, positioning, as well as its contraindications and complications.

    Abstract Introduction: Congestive heart failure (CHF) is a known risk factor for increased postoperative morbidity. However, the safety in patients with CHF has not been well established. The objective of this study was to assess the safety of surgery in patients with a history of CHF undergoing bariatric surgical procedures.
    Methods: Retrospective review of a prospectively maintained Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Center of Excellence database. Patients with known CHF undergoing bariatric procedures over an 11-year period were reviewed.
    Results: Over the 11-year period, 4470 total bariatric surgeries were performed, of which 41 (.92%) patients had known CHF. Twenty-one patients were men (51.2%) with a mean age of 55.8 years and mean body mass index (BMI) of 51.9. Comorbidities included hypertension (87.8%), obstructive sleep apnea (80.5%), osteoarthritis (63.4%), gastroesophageal reflux disease (56%), and diabetes (53.7%). Surgical procedures included 16 sleeve gastrectomies (SGs) (39%), 11 Roux-en-Y gastric bypasses (RYGBs) (26.8%), 10 laparoscopic adjustable gastric bands (LAGBs) (24.4%), 1 removal of a gastric band and conversion to SG (2.4%), 1 removal of a gastric band to RYGB (2.4%), 1 gastric band over RYGB pouch (2.4%), and 1 gastric band replacement (2.4%). All cases were performed minimally invasively (73.2% laparoscopic and 26.8% robotic). Mean LOS was 2.53 days. Thirty-day complications included 2 readmissions (4.9% [1 small bowel obstruction and 1 pulmonary edema]), 1 reoperation (2.4% [small bowel obstruction]), and 1 mortality (2.4%) on postoperative day 30 unrelated to the surgery.
    Conclusions: Bariatric surgery can be performed safely in patients with CHF.

    Abstract Introduction: During the COVID pandemic, elective global surgical missions were temporarily halted for the safety of patients and travelling healthcare providers. We discuss our experience during our first surgical mission amidst the pandemic. We report a safe and successful treatment of the patients, detailing our precautionary steps and outcomes.
    Methods: Retrospective manual chart review and data collection of patients' charts was conducted after IRB approval. We entail our experience and safety steps followed during screening, operating and postoperative care to minimize exposure and improve outcomes during a surgical mission in an outpatient setting during the pandemic. The surgical mission was from February 8 to February 12, 2022.
    Results: A total of 60 patients who were screened. 33 patients underwent surgical intervention. One patient required postoperative hospitalization for a biliary duct leak. No patient or healthcare provider tested positive for COVID at the end of the mission. The average age of patients was 46.9 years. The average operative time was 116 min, and all patients had local nerve blocks. It included 45 health work providers.
    Conclusions: It is safe to perform outpatient international surgery during the pandemic while following pre-selected precautions.

    Abstract Background: Placement of a tracheostomy for patients requiring prolonged mechanical ventilation (PMV) improves patients' comfort, decreases dead space ventilation, allows superior airway hygiene, and reduces the incidence of ventilator-associated pneumonia. Controversy still exists regarding the role of standard tracheostomy (ST) as opposed to the less frequently done Björk flap tracheostomy (BFT). This study compares the functional outcomes of these two techniques.
    Study design: Seventy-nine patients receiving tracheostomy in a 12-month period: 38 BFT vs. 41 ST. Data included demographics, indications for PMV, ventilator days before tracheostomy, time to and a number of patients who passed the fiberoptic endoscopic evaluation of swallowing (FEES), time to and a number of patients decannulated.
    Results: Indications in both groups were PMV from trauma (18/38 vs 15/41), pneumonia (13/38 vs 13/41), and ARDS (7/38 vs 11/4), respectively (p > 0.05). Patients in both groups did not differ with regard to age, sex, GCS, duration of PMV before tracheostomy, the time to and a number of patients who passed the 1st FEES. However, the number of days and the number of FEES required before the next successful FEES in the 20 BFT and 21 ST patients who failed the 1st was 9 (4) vs. 16 (5), and 2 (1) vs. 4 (1), respectively (p < 0.05). Additionally, the number of intraoperative complications in aggregate were 0/38 in the BFT as opposed to 6/41 in the ST group (p < 0.05).
    Conclusion: We conclude that BFT may be associated with an overall shorter time to restoration of normal swallowing when compared to ST.

    Abstract Background/aim: This study represents the first report that evaluates the experience gathered from diagnosis, surgical treatment and outcome of insulinoma patients from Azerbaijan.
    Materials and methods: We retrospectively review of insulinoma patients for a 10-year period. Collected data included patient demographics, laboratory and imaging tests, detailed surgical reports, histopathological examination of resected specimens, and clinical follow-up.
    Results: Twenty-one insulinoma patients were identified. Male patients comprised 52.4%; mean age was 44 years. Mean time to diagnosis was 14 months; 61% patients had ≥3 medical referrals due to hypoglycemia-related symptoms. Diagnosis sensitivity of CT, MRI and US was 85%, 80%, and 55%, respectively. The mean glucose, insulin, C-peptide levels were 35.7 ± 9.5 mg/dL, 33.5 ± 21.9 μU/mL, and 3.74 ± 1.88 ng/mL, respectively. Pancreatic head and tail were the most frequent tumor locations; mean tumor size was 1.5 ± 0.7 cm. No statistical association was found between the tumor size and preoperative glucose, C-peptide and insulin levels. Distal pancreatectomy and enucleation were the most common surgical procedures. Local tumor recurrence rate was 14%. There was no mortality.
    Conclusions: To prevent delayed diagnoses, physicians should be familiar with the typical symptoms of these rare tumors.
