First-World Care at Third-World Rates: Pakistan, an Attractive Destination for Bariatric Tourism.

Introduction Obesity, a complex and multifactorial disease, is defined by a body mass index (BMI) greater than 30 kg/m². When the BMI exceeds 40 kg/m², it is classified as morbid obesity. This condition leads to excessive fat accumulation, which impairs normal body function and metabolism. For individuals grappling with morbid obesity and those who have faced significant hurdles in their quest for substantial weight loss, bariatric surgery emerges as a vital option. Purpose The study aims to explore the dynamics of bariatric surgical tourism in Pakistan, shedding light on factors influencing the choice of Pakistan as a destination for bariatric tourism. Materials and methods A retrospective cross-sectional study design was adopted. Data were gathered from the medical records database, including all patients who had undergone bariatric surgery from 2018 until 2022. The data collection process involved comprehensive patient outreach, where investigators conducted phone interviews and collected patient satisfaction assessments. During these phone interviews, valuable information was gathered by posing questions. These inquiries encompassed various aspects, including the patient's overall satisfaction with the surgical experience, their countries of origin, the specific bariatric procedures they underwent, the motivating factors behind their decision to travel abroad for surgery, their postoperative follow-up routines, and any complications they may have encountered. Results One hundred and nine patients traveled to Pakistan for bariatric surgery from 2018 to 2022. Out of 109 patients, 78 responded to the questionnaire by phone or email. The proforma was filled by 41 (52.5%) males and 37 (47.5%) females. Forty-seven (60.2%) of these patients underwent Roux-en-Y gastric bypass and 31 (39.8%) patients underwent sleeve gastrectomy. Out of 78 bariatric patients, 72 (92.3%) were satisfied with their surgery, five patients (6.4%) were neutral in their response and one patient (1.3%) was dissatisfied with the surgery. Most of the patients (26, 33.3%) declared money as the main driving force for traveling, with long waiting times being the close second reason (19, 24.36%) patients. Conclusion At least 2% of worldwide bariatric procedures are provided for medical tourists. Countries such as Mexico, India, Lebanon, and Romania dominate as providers for patients mainly from the USA, UK, and Germany. The lack of affordable bariatric healthcare and long waiting lists are some of the reasons for patients choosing bariatric tourism. The 92.3% satisfaction rate of patients with the surgery and its outcomes is a significant finding, as it suggests that bariatric surgery services provided in Pakistan are meeting or exceeding the expectations of international patients. The exceptionally high level of patient satisfaction speaks to the quality of care provided by the medical institutions in Pakistan. The data and analysis presented in this study shed light on the motivations and experiences of international patients traveling to Pakistan for bariatric surgery. These insights are invaluable for healthcare providers, policymakers, and the medical tourism industry as they seek to enhance the accessibility, affordability, and quality of healthcare services for domestic and international patients.

Evaluating the use of coronary artery calcium scoring as a tool for coronary artery disease (CAD) risk stratification and its association with coronary stenosis and CAD risk factors: a single-centre, retrospective, cross-sectional study at a tertiary centre in Pakistan.

OBJECTIVE: Coronary artery disease (CAD) risk stratification plays a fundamental role in the early detection and optimal management of CAD. The aim of our study is to investigate the use of coronary artery calcium scoring (CACS) as a tool for CAD risk stratification through evaluation of its correlation with the degree of coronary stenosis and its association with conventional cardiovascular risk factors in asymptomatic patients. DESIGN: Single-centre, retrospective, cross-sectional study. SETTING: The study was conducted at a tertiary centre (Shifa International Hospital) in Islamabad, Pakistan, through review of medical records of patients who underwent coronary CT between the years 2016 and 2020. PARTICIPANTS: A total of 1014 patients were included in the study. The study population was analysed for presence of conventional risk factors (gender, age, diabetes, hypertension, body mass index, dyslipidaemia) and association with CACS (zero: n=534; minimal: 0 to ≤10, n=70; mild: >10 to ≤100, n=130; moderate: >100 to ≤400, n=118; and severe: >400, n=49). The association of CACS with the degree of coronary artery stenosis seen on CT scan (significant: ≥50% stenosis, n=216; non-significant: <50% stenosis, n=685) was also analysed. OUTCOME MEASURES: The main outcome was the association of coronary artery stenosis with CACS. The secondary outcome was the association of CACS with conventional CAD risk factors. RESULTS: A significant positive association was shown between CACS and coronary artery stenosis (zero vs minimal: OR 0.39, 95% CI 0.20 to 0.79, p=0.01; zero vs mild: OR 0.16, 95% CI 0.10 to 0.27, p<0.0001; zero vs moderate: OR 0.05, 95% CI 0.03 to 0.08, p<0.0001; zero vs severe: OR 0.02, 95% CI 0.01 to 0.050, p<0.0001). Age >45 (OR 1.03, 95% CI 1.01 to 1.05, p<0.0001), hypertension (OR 1.16, 95% CI 0.79 to 1.71, p=0.001) and diabetes (OR 1.33, 95% CI 0.88 to 1.99, p<0.0001) were associated with an increased risk of coronary artery stenosis. Moreover, plaques with higher calcium burden were found in the left anterior descending artery (mean CACS: 386.15±203.89), followed by right coronary (239.77±219.83) and left circumflex (175.56±153.54) arteries. CONCLUSION: The results indicate a strong positive association of CACS with coronary artery stenosis. CACS was also significantly associated with conventional CAD risk factors in this population.

Diagnostic, Surgical, and Postoperative Challenges of Neuroendocrine Tumors of the Neck: Clinical Experience and Literature Review.

BACKGROUND: Neuroendocrine tumors of the neck are rare swellings, which constitute about 0.03% of all tumors. Most are sporadically arising paragangliomas. Over 50% arise from the carotid bodies and pose difficulties in diagnosis and surgical management, which may result in disabling complications. OBJECTIVE: To determine the diagnostic, surgical, and postoperative challenges, and how to overcome them, in the management of neuroendocrine tumors of the neck. STUDY DESIGN: Descriptive case series. METHODS: A retrospective analysis of 19 patients who presented to our surgery clinics between 2010 and 2015 with neck swelling and suspicion of neurogenic tumors were included in the study. All patients received preoperative evaluation with Doppler studies and neck computed tomography scan, with the finding of suspicion of neurogenic tumor. Preoperative tissue diagnosis was not attempted as this usually required excisional biopsy. All tumors were surgically excised. Data regarding mean tumor size, neurovascular invasion, postoperative complications, and histopathological findings were recorded and statistically analyzed. RESULTS: Nineteen patients (7 male) with median age of 45 years were included. Mean size of the tumor was 7.5 cm (range: 4.0-11.8 cm). Six of the tumors were right sided and 13 left sided. Clinical findings often were nonspecific and mimicked other conditions. Operative challenges were encountered in 11 (57.9%) patients, who had tumors of more than 5 cm. Vascular invasion was found in 2 (10.5%) patients, but bleeding requiring preoperative transfusion was not required in any patient. Neurological complications occurred in 11 (57.8%) patients; 3 had transit hypoglossal nerve palsy, with full recovery; 2 had complete nerve palsy, with reasonable rehabilitation without further surgical intervention; and 5 developed neurological deficits (hoarseness, dysphagia, or Horner's syndrome) but recovered and compensated well without further operation. Two patients who had vascular invasion required vascular reconstruction. Histopathology in 14 (73.7%) cases was carotid body tumor and 5 were Schwannomas (1 vagal and 4 sympathetic chain). All 4 patients with Schwannomas of cervical sympathetic chain developed Horner's syndrome; 2 of them have compensated well with reasonable recovery; 2 have had tarsorrhaphy for cosmetic reasons. The patient with vagal Schwannoma developed hoarseness and swallowing difficulties, which resolved without intervention. No malignancy was encountered in this series, and there was no mortality. CONCLUSIONS: Neuroendocrine tumors of the neck present diagnostic challenges because of nonspecific clinical findings mimicking other conditions. Preoperative tissue diagnosis is mostly unsuccessful, and exact diagnosis requires excisional biopsy. Surgical excision, which is the main treatment, often has associated technical difficulties and unavoidable complications requiring further intervention.
