A Case of a Gastric Stent Complication Presenting With a Gastrojujenal Fistula.

Laparoscopic sleeve gastrectomy (SG) is a widely performed bariatric procedure known for its safety and efficacy, yet complications, particularly postoperative leaks, remain a concern. Endoscopic stenting is one of the approaches for leak management that has some complications such as the rare fistula with adjacent organs. Here, we present a unique case of a 56-year-old diabetic female who developed a gastroenteric fistula following endoscopic stent placement for a post-SG leak. The patient had a delayed stent removal, and three weeks later she presented with dysphagia and vomiting in a follow-up appointment. Esophagogastroduodenoscopy (EGD) showed an esophageal stricture and a large gastroenteric fistula that was confirmed by imaging to be a fistula between the pylorus and proximal small bowel. The patient's symptoms improved gradually with conservative management, and imaging showed the resolution of the fistula and associated esophageal stricture. This case highlights the importance of timely stent removal (ideally within 6-8 weeks) and close follow-up with EGD and CT to detect and manage potential complications, while emphasizing the need for further research on optimal stent placement duration.

The Effect of Bariatric Surgery on Metabolic Syndrome: A Three-center Experience in Saudi Arabia.

PURPOSE: The prevalence of metabolic syndrome (MetS) increases in parallel with the increasing incidence of obesity. Hence, bariatric surgery is potentially curative in obese patients with MetS. We aim to measure the effect of bariatric surgery as well as the potential factors leading to MetS resolution in the Saudi population. METHODS: A retrospective review of three tertiary care centers in Saudi Arabia was done. We identified 386 patients who have MetS and underwent bariatric surgery during the period between January 2016 and December 2018. After exclusion of patients with insufficient follow-up, data from 275 patients was analyzed. MetS diagnosis, persistence, and resolution were determined using the International Diabetes Federation consensus worldwide definition. RESULTS: MetS resolution was achieved in 78%, 79%, 73%, and 82% at 1, 2, 3, and 4 years after bariatric surgery, respectively. Accumulatively, 80% achieved MetS resolution with an average follow-up period of two and a half years. Patients who experienced resolution had younger age, lower BMI, lower systolic blood pressure, lower triglycerides, lower fasting plasma glucose, and lower HbA1c preoperatively in addition to a higher percentage of excess weight loss after bariatric surgery when compared to those who had persistence of MetS. CONCLUSION: More than three fourths of patients with MetS achieved resolution after bariatric surgery. Certain patient characteristics, such as young age and higher excess weight loss postoperatively, were associated with a higher chance of MetS resolution.

An insidious case of infectious mononucleosis presenting with acute appendicitis diagnosed postoperatively: a case report.

Infectious mononucleosis (IM) is a syndrome caused by the Epstein-Barr virus. IM typically presents with fever, pharyngitis and lymphadenopathy. Rarely, it can cause acute appendicitis. We report the case of a 19-year-old female presenting with a chief complaint of colicky, non-radiating abdominal pain for 2 days. Abdominal examination revealed rebound tenderness in right iliac fossa tenderness and splenomegaly. The diagnosis of acute appendicitis was confirmed by computed tomography. She underwent laparoscopic appendectomy and mesenteric lymph node biopsy. She was later diagnosed with IM based on laboratory findings and histopathology results. She received a course of intravenous acyclovir and was discharged. This shows that IM may present with acute appendicitis as the initial presentation and may not be accompanied by any other significant symptoms of IM.

Preoperative Helicobacter pylori Screening and Treatment in Patients Undergoing Laparoscopic Sleeve Gastrectomy.

BACKGROUND: The role of preoperative screening and treatment of Helicobacter pylori (HP) in asymptomatic patients undergoing laparoscopic sleeve gastrectomy (LSG) remains unclear. This study aims to define the preoperative prevalence and management of HP and their effect on postoperative outcomes at our institution. MATERIALS AND METHODS: We reviewed the medical records and surgical specimens of all LSG performed at an academic centre in Toronto, ON between 2010 and 2017. RESULTS: Review of our institutional database identified 222 patients that underwent LSG, of which 200 had preoperative HP screening: 18% tested positive and 15% were treated. Seven surgical specimens were HP-positive (3.2%). No association was found between preoperative HP status, treatment or HP-positive specimen and postoperative complications at 1 year. CONCLUSION: Although preoperative screening and treatment likely reduce the prevalence of HP in LSG specimens, our findings suggest that they may be of limited clinical value in LSG as they have little influence on surgical morbidity.

Unexpected histopathological findings after sleeve gastrectomy.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) represents one of the most commonly performed bariatric procedures and, in contrast to the Roux-en-Y gastric bypass, produces a specimen for pathologic examination. This study aims to describe unexpected histopathological findings in order to better define preoperative management of patients undergoing LSG. METHODS: All LSG cases performed at an academic center in Toronto, Ontario between 2010 and 2017 were reviewed. All specimens underwent histopathological assessment, while those with findings suspicious for neoplasia or the presence of Helicobacter pylori underwent additional immunohistochemical stainings. Baseline patient characteristics and surgical outcomes were obtained from our internal database. RESULTS: A total of 222 patients underwent LSG during the study period and had their specimens examined histologically. Among them, 22.5% underwent preoperative endoscopy. The most common histopathological diagnosis was no abnormal findings (50.9%) followed by gastritis (25.7%). Abnormal findings warranting a change in postoperative management or follow-up were discovered in 8.6% of specimens and included H. pylori infection, intestinal metaplasia, malignancy, and atrophic gastritis. Only 4.7% of all patients had not undergone preoperative endoscopy and had truly unexpected findings. No significant association was found between abnormal findings and age, sex, or baseline body mass index (BMI). CONCLUSIONS: Although a majority of patients had a gastric specimen within normal limits, 8.6% had findings requiring a change in postoperative management. This rate dropped to 4.7% when patients whose diagnoses were known preoperatively were excluded. Our findings suggest that further research is needed to better define the role of preoperative endoscopy to potentially reduce the number of unexpected findings following LSG.

Epidemiology of traumatic head injury in children and adolescents in a major trauma center in Saudi Arabia: implications for injury prevention.

BACKGROUND AND OBJECTIVES: Injury to the head is the most common affected body part in pediatric trauma and could be associated with deleterious consequences. It presents a challenge for developing countries since many injuries are preventable and there are few epidemiological data to support injury prevention programs. The current study aimed to determine demographic characteristics, etiology and outcome of head injury in the pediatric population and compare findings to international figures. DESIGN AND SETTINGS: Retrospective review of consecutive cases registered in major trauma center database, Riyadh, from 2001 to 2009. PATIENTS AND METHODS: The database registry was limited to hospitalized patients following injury. Any head injury in a patient ≤18 years was included. RESULTS: Of 3796 patients identified, 1219 patients (32.1%) suffered head injury (mean age 8.6 years; males 78.4%). Children under 12 years comprised 66.3%. Motor vehicle crash (MVC) was the commonest cause (34.2%), followed by pedestrian injury (30.3%) and falls (28.4%). When stratified by age, falls (45.6%) were the most common etiology under 6 years while MVC was the leading cause in high school students (74.4%). The latter group had the lowest mean (SD) Glascow coma scale scores ( 8.58 [4.7]), highest mean injury severity scale scores (23.4 [21]), highest rate of craniotomy (7%) and highest mortality (20%). CONCLUSION: One third of pediatric trauma requiring hospital admission suffered head injury. Preschoolers and elementary school students were mostly affected. The striking incidence of pedestrian and fall injuries call for organized national prevention programs. Additionally, more attention should be directed to reduce MVC among high school students given their comparative high rate of severe injuries and deaths following trauma.

Toward an objective assessment of technical skills: a national survey of surgical program directors in Saudi Arabia.

BACKGROUND: After almost a decade of implementing competency-based programs in postgraduate training programs, the assessment of technical skills remains more subjective than objective. National data on the assessment of technical skills during surgical training are lacking. We conducted this study to document the assessment tools for technical skills currently used in different surgical specialties, their relationship with remediation, the recommended tools from the program directors' perspective, and program directors' attitudes toward the available objective tools to assess technical skills. METHODS: This study was a cross-sectional survey of surgical program directors (PDs). The survey was initially developed using a focus group and was then sent to 116 PDs. The survey contains demographic information about the program, the objective assessment tools used, and the reason for not using assessment tools. The last section discusses the recommended tools to be used from the PDs' perspective and the PDs' attitude and motivation to apply these tools in each program. The associations between the responses to the assessment questions and remediation were statistically evaluated. RESULTS: Seventy-one (61%) participants responded. Of the respondents, 59% mentioned using only nonstandardized, subjective, direct observation for technical skills assessment. Sixty percent use only summative evaluation, whereas 15% perform only formative evaluations of their residents, and the remaining 22% conduct both summative and formative evaluations of their residents' technical skills. Operative portfolios are kept by 53% of programs. The percentage of programs with mechanisms for remediation is 29% (19 of 65). CONCLUSION: The survey showed that surgical training programs use different tools to assess surgical skills competency. Having a clear remediation mechanism was highly associated with reporting remediation, which reflects the capability to detect struggling residents. Surgical training leadership should invest more in standardizing the assessment of surgical skills.
