Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver diseases, along with steatosis and non-alcoholic steatohepatitis (NASH), and is associated with cirrhosis and hepatocellular carcinoma. Candidate gene and genome-wide association studies have validated the relationships between NAFLD, NASH, PNPLA3, TM6SF2, and HFE. The present study utilized five polymorphisms in three genes: PNPLA3 (I148M and K434E) TM6SF2 (E167K), and HFE (H63D and C282Y), based on undocumented case–control studies in the Saudi Arabian population. A total of 95 patients with NAFLD and 78 non-NAFLD subjects were recruited. Genomic DNA was isolated, and polymerase chain reaction and Sanger sequencing were performed using specific primers for the I148M, K434E, E167K, H63D, and C282Y. NAFLD subjects were older when compared to controls and showed the significant association (p = 0.0001). Non-significant association was found between gender (p = 0.26). However, both weight and BMI were found to be associated. Hardy–Weinberg equilibrium analysis confirmed that H63D, I148M, and K434E polymorphisms were associated. Genotype analysis showed only K434E variant was associated with NAFLD and non-NAFLD (OR-2.16; 95% CI: 1.08–4.31; p = 0.02). However, other polymorphisms performed with NAFLD and NASH were not associated (p > 0.05), and similar analysis was found when ANOVA was performed (p > 0.05). In conclusion, we confirmed that K434E polymorphism showed a positive association in the Saudi population.

Introduction and importance: The literature described Candy cane syndrome (CCS) as causing various symptoms and affecting patients' quality of life. Most of the literature described this syndrome occurrence at gastrojejunostomy (GJ) anastomosis. The literature lacks data on this syndrome occurring at the jejunojejunostomy (JJ). Case presentation: We describe a patient who underwent revision of laparoscopic gastric bypass (LGB) due to weight regain and presented three days after the procedure with small bowel obstruction (SBO). The patient was admitted as she demonstrated a picture of SBO. A complete workup and contrast study was done and showed dilated bowel loops. The patient was taken for exploratory laparoscopy, which revealed dilated 10–15 cm candy cane near the JJ, causing and obstruction. Resection of the elongated blind pouch was done, and the patient tolerated the surgery with improvement in her symptoms. Preoperative imaging, perioperative management, procedure videos, and follow-up were used to describe the case. Clinical discussion: After reviewing the literature, eight papers reported CCS, 7 of those articles mentioned the syndrome located at the GJ. CCS located near the JJ can lead to symptoms including SBO. Management is mainly surgical, and prevention of occurrence can be achieved by limiting unnecessary elongated blind pouches. Conclusion: CCS is a well-established condition occurring at the GJ following LGB, but it can manifest similarly if an elongated blind limb is left unresected at the JJ. Highlights:

Concomitant surgery is an attractive option because of convenience. To our knowledge, this is the first study reporting concomitant laparoscopic sleeve gastrectomy (LSG) and laparoscopic right adrenalectomy. A retrospective review of three patients with obesity and a unilateral adrenal mass was conducted. The demographics, workup, surgical technique and outcome were presented. Patient 1 had a body mass index (BMI) of 41 kg/m2, diabetes mellitus (DM), hypertension (HTN) and a right adrenal pheochromocytoma. Patient 2 had a BMI of 40 kg/m2, insulin-dependent DM, uncontrolled HTN, chronic kidney disease, ischemic heart disease and an aldosterone secreting right adrenal adenoma. Patient 3 had a BMI of 41 kg/m2, dyslipidemia, HTN and gout. All patients underwent concomitant LSG and laparoscopic adrenalectomy (LA). LSG and LA is a feasible and safe concomitant surgery when performed under specific measures with minimal morbidity and more convenience.

This is the first report of a patient presenting with a splenic pseudocyst following laparoscopic sleeve gastrectomy (LSG). A 26-year-old male with no chronic medical illnesses who underwent LSG presented with vague abdominal pain. An abdominal contrast-enhanced computed tomography revealed a 15 cm well-circumscribed cyst originating from the spleen. Intraoperatively, the findings were significant for a superficial cyst located at the lower pole of the spleen. A laparoscopic spleen-preserving procedure was conducted, specifically marsupialization and packing with omentum. The postoperative period was uneventful, and the patient was discharged on Day 2 postoperatively. The patient was free from complaints at outpatient follow-up clinics. Follow-up visits at the outpatient clinic were free from complaints. Pathology confirmed a splenic pseudocyst, and cytology was unremarkable. Since dissection during LSG is close to the spleen, infarction could occur, predisposing to pseudocyst formation. Marsupialization is an excellent surgical option when applied to appropriate splenic cyst types.
