The Descriptive Features of Primary Spontaneous Pneumothorax Patients in King Abdulaziz Medical City, Riyadh, Saudi Arabia.

Background Primary spontaneous pneumothorax (PSP) is a fairly prevalent disorder in emergency medicine. PSP most frequently affects tall, thin male smokers and is most prevalent during adolescence. Published literature contains a wide range of Primary Spontaneous Pneumothorax (PSP) recurrence rates, but there is limited information on the variables affecting recurrence. Objective To identify the descriptive features of PSP in King Abdulaziz Medical City, Riyadh, Saudi Arabia. Methods This retrospective cross-sectional study was conducted in Surgery King Abdulaziz Medical City, Riyadh, Saudi Arabia. Including all PSP patients from 2016-2021, excluding pediatric and geriatric patients. Participants were selected using a simple random sampling technique, and data were collected from hospital records. Data analysis was conducted by using SPSS. Results In this study, we included a total of 131 participants. Most were males (93.1%), and most were aged between 21-30 years. Our findings showed that most PSP events occurred in winter (28.6%). Followed by fall (25.7%), summer (25.0%), and spring (20.7%). Concerning the smoking status of our respondents, our results revealed that most of them were active smokers (72.5%). Left-PSP was the most commonly reported type of PSP (43.5 %), followed by right-PSP (38.9%), non-simultaneous bilateral PSP (14.5%), and bilateral simultaneous PSP (3.1%). Moreover, we found that the recurrence rate of PSP was 42%. Regarding the management of PSP, almost half of the respondents were managed initially by Chest tube. The most frequently used surgical option was VATS- Bullectomy with Abrasion Pleurodesis. Finally, the recurrence rate of PSP was 42% among the patients. The percentage of patients with one recurrence only was 65.5% among the patients with recurrent PSP, second recurrence at 29.1%. Third, Fourth, and Fifth had the same recurrence percentage of 1.8%, and these percentages came to be statistically significant. (P value < 0.001) Conclusion Our study concluded that PSP was more prevalent in tall, thin, young male smokers. Almost half of the respondents suffered from at least one recurrence attack of PSP. The majority of the patients with recurrences experienced one recurrence only, and the second recurrence was estimated to be almost one-third. There is no significant association between the occurrence and seasons of the attack at a time. Most of the participants were managed initially by a chest tube. The most frequently used surgical option was Video Assisted Thoracoscopic Surgery (VATS) with abrasion pleurodesis.

Bronchoscopic resection of typical carcinoid tumors: literature review and case series.

Carcinoid tumors have been treated with formal oncological surgical resection, which is considered the gold standard approach. In the past two decades, bronchoscopic has gained popularity for treatment of carcinoid tumors. A 34-year-old female with an unresolving chronic cough, underwent a chest CT that showed right endobronchial lesion. Bronchoscopy and a biopsy were taken from the lesion; pathology confirmed the diagnosis to be a typical carcinoid tumor. Forty-six-year-old male, who was a smoker, suffered from hemoptysis. Pathology revealed it to be an endotracheal typical carcinoid tumor at the carina. Uncertainties, such as chances of recurrence, cost-effectiveness and the inability to achieve formal oncological resection have been discussed and challenged in the literature. With gaining use of this treatment approach, tissue-sparing surgery for carcinoids can improve patient quality of life both in the short and long term.

Compliance to endoscopic retrograde cholangiopancreatography according to current guidelines and adverse outcomes of suspected choledocholithiasis in an acute care setting.

INTRODUCTION: Common bile duct (CBD) stones are common among patients who underwent cholecystectomy. However, few studies have investigated the compliance with the guidelines for the prediction of choledochlithiasis (CL). Therefore, we aim to study the compliance with the American Society for Gastrointestinal Endoscopy (ASGE) guidelines for the identification of CL in a major hospital in Saudi Arabia's capital. METHODS: We conducted a retrospective chart review on adult patients admitted to emergency department at King Abdulaziz Medical City, Riyadh with gallstones between January 2016 and January 2019. Our data collection includes demographics and level of suspicion based on Transabdominal Ultrasound, liver function, amylase, and lipase tests. We then determined the likelihood of CL based on ASGE guidelines in order to assess the adherence to ASGE guidelines, the procedure's outcomes and adverse outcomes. RESULTS: We identified 826 patients who met the study's criteria: 384 (46.4%) were compliant, while 442 (53.6%) were non-compliant with ASGE guidelines. There was a significant association between compliance and the presence of stones on ERCP in high likelihood patients. 48 (21.3%) of total ERCP procedures among all the likelihoods had adverse outcomes. 13 (40.6%) of non-compliant ERCP performed in intermediate likelihood have experienced adverse outcomes. There was a significant association between having adverse outcomes and being non-complaint with ASGE guidelines. CONCLUSION: Despite ASGE guidelines' recommendations, a third of high likelihood cases and the majority of intermediate likelihood cases were non-compliant. Additionally, the current guidelines for the intermediate group are somewhat vague, giving ample leeway for patients to be placed in the intermediate group, which might subject them to unnecessary interventions. To conclude, there was a great lack of compliance with ASGE guidelines that is significantly associated with adverse outcomes. Hence, reassessing the current guidelines and monitoring healthcare facilities' compliance with the updated guidelines is highly recommended.

Outcomes of emergency appendectomies and cholecystectomies performed at weekends.

PURPOSE: To determine the impact of hospital admissions and operations at weekends on two common emergency general surgeries (cholecystectomy and appendectomy) and their outcomes. METHODS: A total of 539 patients were included in the study. Information on patient demographics, comorbidities, admission date, surgery date, complications, readmission, and follow-up details were collected from electronic medical records. RESULTS: Most patients were admitted to hospital on weekdays (n = 391), and 444 surgeries were performed on weekdays, while 86 surgeries were performed at weekends. No significant difference was found between the type of surgery performed on weekday and weekend admissions (P = 0.384). Surgical procedures of patients admitted to hospital on a weekend tended to be delayed by a median of one day compared with weekday admissions, with a similar overall length of stay for both groups. Weekend admissions were associated with higher complication rates than weekday admissions (12.2 vs. 6.1%). Patients who were operated on at weekends were younger in age than those admitted on weekdays (32 vs. 30 years old, P = 0.019). More appendectomies were performed at weekends (77.9% vs. 45.9%), and fewer cholecystectomies were performed (22.1 vs. 54.1%, P = 0.000). CONCLUSIONS: The surgical procedures of patients admitted to hospital on weekends tended to be delayed by 1 day and had a higher rate of complications. Appendectomy was the most common performed weekend surgery.

Complications of Veress Needle Versus Open Technique in Abdominal Surgeries.

Introduction In any laparoscopic procedure, the first and most important step is abdominal entry. This is followed by the creation of pneumoperitoneum, which is essential for lifting the abdominal wall off of the internal organs and visualizing the entered space. However, the entry and establishment of pneumoperitoneum are not without risks and complications, the most serious of which include vascular injuries and bowel perforations in all the different techniques used. The most commonly used techniques for abdominal entry are the closed (Veress) and open (Hasson) techniques, the choice of which varies according to the surgeon's preference and other regional and local factors. Aim To compare the outcomes between the open technique and the Veress needle for accessing the peritoneum during laparoscopic surgery. Methodology This was a retrospective cohort study that aimed to compare the outcomes between the Veress needle and the open technique for entering the peritoneum in laparoscopic surgeries. A chart review was used as an instrument to collect data. The study was conducted in King Abdul-Aziz Medical City, Riyadh, Saudi Arabia. All patients who underwent abdominal laparoscopic surgery from 2006 to 2016 were included. Results We analyzed 365 patients who underwent laparoscopic abdominal surgery. The mean age of the patients was 32.6 years. The most common postoperative complication occurring during the admission period was abdominal pain (40.5%). Postoperative complications during admission were significantly associated with the type of needle used (χ2=10.641; p=0.001). Conclusion The type of technique used for entry and peritoneal access was associated with the occurrence of postoperative complications in abdominal surgeries. Thus, the choice of open or Veress technique for peritoneal access should be individualized based on factors such as patient sex, clinical diagnosis, and most importantly, the surgeons' experience and preference.

Do We Feel Safe About the Surgical Safety Checklist? A Cross-Sectional Study Between Two Periods.

Introduction: The aim of this study was to evaluate the change in the healthcare providers' perceptions regarding the World Health Organization Surgical Safety Checklist (WHO SSC) and patient safety in the operating room (OR) at a tertiary hospital in Riyadh, Saudi Arabia. Methods: This cross-sectional study was conducted at King Abdulaziz Medical City. Data were collected from two years (2011 and 2019) for comparison. The co-investigators distributed a self-administered Likert scale questionnaire in the various operating areas (35 ORs). Results: The total sample was 461. Number of participants enrolled from both years was 235 (51%) and 226 (49%), respectively. The results indicated a statistically significant difference in the attitude of the participants regarding all aspects of patient safety in the OR when the two periods were compared (p < 0.001). Similarly, healthcare providers' perceptions regarding the importance of the WHO SSC increased from 50% (2011) excellent to 68% excellent (2019) (p < 0.001). Conclusions: Currently, more healthcare providers recognize the importance of the WHO SSC, and more have a positive attitude toward teamwork, communication, and feeling free to speak out when surgical safety is compromised. All of these cultural changes have positive impact on the overall safety of the OR; however, there are still aspects requiring improvement to provide a safer OR and surgery. Educational interventions regarding the importance of communication and teamwork would improve the safety of surgical care in the OR.

Trends in bariatric surgery and incidentalomas at a single institution in Saudi Arabia: a retrospective study and literature review.

BACKGROUND: Data are lacking on trends in bariatric surgery and the frequency of incidental findings in Saudi Arabia. OBJECTIVE: Report on trends in bariatric surgery as well as our experience in incidental findings along with a literature review (mainly on gastrointestinal stromal tumor). DESIGN: Retrospective chart and literature review. SETTINGS: Academic tertiary care center. PATIENTS AND METHODS: We conducted a retrospective study at King Khalid University Hospital and analyzed the data collected from 2009 to 2019. We collected data on age, body mass index (BMI), H pylori infection, type of bariatric surgery performed, and type and location of incidental findings. MAIN OUTCOME MEASURES: Incidental findings during or after bariatric surgery (in pathology specimen). SAMPLE SIZE: 3052 bariatric surgeries, 46 patients with incidentalomas. RESULTS: The mean and standard deviation for the age of the 46 patients with incidentalomas was 42.1 (13.9) years and the mean (SD) preoperative BMI was 43.4 (6.4) kg/m2. Of 3052 bariatric surgeries performed, the most common type was sleeve gastrectomy (93.9%), followed by gastric bypass surgery (4.58%) and gastric banding (1.47%). The total frequency of incidentalomas was 1.5%; 10.8% of patients had gastrointestinal stromal tumors (GIST), with the stomach being the commonest site for incidental findings. Eighty percent of the patients with GIST were positive for H pylori (P=.01 vs negative patients). CONCLUSION: The number of incidentalomas and other findings were consistent with other reports. All these findings suggest that bariatric surgeons should take special care before, during, and after a laparoscopic operation in obese patients. LIMITATIONS: Since this is a single-center, retrospective study, we did not collect data on important variables such as gender, socioeconomic status of the patient, and family history of obesity, and we did not perform a preoperative esophagogastroduodenoscopy. CONFLICT OF INTEREST: None.

Characteristics of morbid obese patients with high-risk cardiac disease undergoing laparoscopic sleeve gastrectomy surgery.

INTRODUCTION: Bariatric surgery is an efficient and safe method of weight reduction among patients who have morbid obesity which cannot be treated by the conservative approach. Safety and feasibility of bariatric surgery among high-risk patients are understudied. Therefore, we aimed to report the patient-level characteristics and outcome among high-risk obese patients undergoing laparoscopic sleeve gastrectomy surgery in Saudi Arabia. METHODS: A retrospective analysis was performed among 13 morbidly obese (BMI >39 kg/m2) patients with high-risk cardiac disease, who were referred to Upper Gastro-Intestinal Surgery Clinic at King Khalid University Hospital, which is a center of excellence in bariatric surgery, for consideration for weight loss surgery. Retrospective data on preoperative weight, height, and BMI, operative details, perioperative complications, length of stay, and information on comorbidities and endocrinal disease were collected for analysis and reporting. RESULTS: A total of 13 patients were included in the analysis. Of the total, 61.5% were males with a mean age 40.38 (SD: 16.28) and a mean BMI 51.87 (SD: 7.69). The mean duration of surgery was 33.30 min (SD: 31.01), while the mean duration of anesthesia was 83.61 min (SD: 34.73). The mean length of stay was 6.76 days (SD: 3.89). Three patients required postoperative HDU admission with a mean length of stay of 1 day, while 5 patients required postoperative ICU admission with a length of stay ranging from 1 to 3 days. Within 30 days after discharge, only 1 patient required ER visit and none of the patients reported any postoperative morbidity and mortality. CONCLUSION: Through this study, we can conclude that laparoscopic sleeve gastrectomy surgery can be considered a safe procedure. However, further studies with a large sample size and a more robust methodology are needed to build upon the findings of this study.

Prevalence and Risk Factors of Gastroesophageal Reflux Disease in Southwestern Saudi Arabia.

Background Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal disorders that has substantial health and economic consequences. Several modifiable risk factors are associated with GERD, hence we conducted the present study to assess the prevalence and risk factors of GERD in a previously understudied population of southwestern Saudi Arabia. Methods A cross-sectional study was carried out to calculate the prevalence of GERD and assess its risk factors. A structured self-administered questionnaire was distributed on a random sample of 853 participants from Jazan region, Saudi Arabia. The questionnaire consisted of questions on the participants' sociodemographic and lifestyle characteristics. The presence of GERD was detected using the GERD questionnaire (GerdQ). Data were analyzed using descriptive statistics and chi-square test, with a significance level of P < 0.05 or P < 0.01. Results The study included 853 participants; 69.1% males and 30.9% females. The proportion of participants who scored >8 on the GerdQ (had GERD) was 32.2%. GERD was associated with age (P < 0.01), marital status (P < 0.01), employment status (P < 0.01), fast food intake (P < 0.01), analgesics use (P < 0.01), and smoking (P < 0.01). GERD was more common among Khat chewers compared to non-Khat chewers (P < 0.05) and showed a significant association with the frequency of Khat use. Conclusion The results show a high prevalence of GERD in the general population of Southwestern Saudi Arabia. Several sociodemographic and lifestyle characteristics were associated with the disease.

Incidental Duodenal Pancreatic Heterotopia During Laparoscopic Sleeve Gastrectomy: A Case Report and Literature Review.

BACKGROUND Heterotopic pancreas is pancreatic tissue that presents outside the normal anatomical location. It is mostly discovered in the upper gastrointestinal tract (mostly the foregut). We report the first case report of incidentaloma of duodenal heterotopic pancreas in obese patients during laparoscopic sleeve gastrectomy. CASE REPORT A 15-year-old Saudi male obese patient was admitted electively for laparoscopic sleeve gastrectomy. Incidentally, during intraoperative procedure, a duodenal nodule was noted in the first part of the duodenum. A wedge resection of the mass was done after a standard laparoscopic sleeve gastrectomy was accomplished and it had an uneventful postoperative course. The histopathological examination showed heterotopic pancreas tissue. CONCLUSIONS Gastrointestinal stromal tumors are found to be the most common incidental pathology during bariatric surgery. The safety and efficacy of excision of similar lesions during laparoscopic sleeve gastrectomy needs to be further investigated.

Inflammatory fibroid polyps of the appendix: different presentation and literature review.

Inflammatory fibroid polyps (IFPs), or Vanek's tumor, are rare benign mesenchymal lesions of the gastrointestinal tract (GIT). IFPs can be found throughout the GIT but most frequently in gastric antrum or ileum, with the appendix accounting for only <1% of all IFPs. The clinical presentation is usually vague yet depends on the location. We report a case of 50-year-old healthy male presented to the emergency department with a sub-acute complaint of non-specific abdominal pain, which was suspected to be appendicitis. Abdominal CT scan was done as well as colonoscopy and histopathology were scheduled. A week later, he presented in the clinic, still complaining of abdominal pain; thus, the decision was made to schedule him for laparoscopy with appendectomy. Finally, the post-operative course was unremarkable and the patient was discharged home. This is a rare case of IFPs originating in the appendix presenting as an atypical sub-acute appendicitis.

Outcomes of common general surgery procedures for patients discharged over weekends at a tertiary care hospital in Saudi Arabia.

BACKGROUND: Hospitals usually reduce staffing levels and services over weekends. This raises the question of whether patients discharged over a weekend may be inadequately prepared and possibly at higher risk of adverse events post-discharge. OBJECTIVES: To assess the outcomes of common general surgery procedures for patients discharged over weekends, and to identify the key predictors of early readmission. DESIGN: Retrospective cohort study. SETTING: A tertiary care center. PATIENTS AND METHODS: Patients discharged from general surgery services during the one-year period between January and December 2016 after cholecystectomy, appendectomy, or hernia repairs were included. Patient demographic information, comorbidities, and complications as well as admission and follow-up details were collected from electronic medical records. MAIN OUTCOME MEASURES: Outcomes following weekend discharge, and the predictors of early readmission. SAMPLE SIZE: 743 patients. RESULTS: The operations performed: 361 patients (48.6%) underwent a cholecystectomy, 288 (38.8%) an appendectomy, and 94 (12.6%) hernia repairs. A significantly lower number of patients were discharged over the weekend (n=125) compared to those discharged on weekdays (n=618). Patients discharged during the weekend were younger, less likely to have chronic diseases, and had a significantly shorter average length of stay (LOS) (median 2 days, IQR: 1, 4 vs. median 3 days, IQR: 1, 5, P=.002). Overall, the 30-day readmission rate was 3.2% (n=24), and weekend discharge (OR=2.25, 95% CI 0.52-9.70) or any other variable did not predict readmission in 30 days. However, 14-day post-discharge follow-up visits were significantly lower in the weekend discharge subgroup (83.1% vs. 91.2%, P=.006). CONCLUSION: Weekend discharge was not associated with higher readmission rates. Physicians may consider discharging post-operative patients over a weekend without an increased risk to the patient. Day of discharge, length of stay and increased patient age are not predictors of early readmission. LIMITATIONS: Single-center study and retrospective. CONFLICT OF INTEREST: None.
