Background: Obesity is a known risk factor for cancer, and bariatric surgery is increasingly used in obese patients. The single anastomosis jejunal bypass (SASJ) is a newer bariatric procedure, but its efficacy and safety remain unclear, especially regarding its impact on cancer risk and management. Methods: We present a case of a 62-year-old female with obesity who underwent SASJ six years prior and developed symptoms suggestive of gastric cancer. Despite initial challenges in diagnosis due to post-SASJ anatomy changes, a thorough evaluation led to the diagnosis of early-stage adenocarcinoma of the antrum. Results: The patient underwent successful total gastrectomy with D2 lymph node dissection and Roux-en-Y esophagojejunostomy. Pathological analysis revealed a PT1 N0 Mx stage tumor with a signet ring cell appearance, highlighting the challenge of diagnosing and managing cancer in post-bariatric surgery patients. Conclusion: This case underscores the importance of considering the impact of bariatric surgery on cancer diagnosis and treatment. Further research is needed to better understand the long-term effects of SASJ on cancer risk and management in obese patients.

Vesicouterine fistula is one of the rare urogenital fistula, usually following C/S. Youssef syndrome is characterized by hematuria, amenorrhea, and urinary incontinence. To confirm the diagnosis for these patients necessitated a comprehensive history and combination of diagnostic modalities, we present the case of complete opening of the anterior uterine wall into the urinary bladder with classic symptoms of Youssef syndrome following the 4th time C/S. sonography and cystoscopy were used for anatomical determination. Transabdominal total hysterectomy, partial cystectomy, and repair were done.

Adrenocortical tumors, while rare in childhood, exhibit aggressive traits, often diagnosed in early childhood or during adolescence. This case report centers on an 8-year-old girl presenting with severe virilization, hirsutism, and sound harshness, persisting for 8 months. Prior medical treatments had been administered thrice before her admission to the pediatric ward for further investigation. Imaging studies revealed a sizable homogeneous mass measuring 65x52x53 mm in the right adrenal gland. Laboratory tests indicated elevated adrenal androgens. Postoperative pathology identified the mass as an adrenocortical neoplasm, favoring a benign type, with a tumor weight of 125 grams and a size of 7 cm. The report indicated no identified venous invasion, extension into peripheral tissue, capsular invasion, tumor necrosis, or atypical mitosis. Notably, while virilization was present in 60% of cases, in this instance, it was predominantly associated with Cushingoid features. The findings corroborate prior studies noting a predilection for right-sided carcinomas, and they highlight the delayed presentation of adenomas, contrasting with the earlier presentation of carcinomas in childhood adrenocortical tumors.

Esophageal achalasia, a rare primary motility disorder, stems from the loss of inhibitory nitregic neurons within the esophageal myenteric plexus, leading to impaired peristalsis and sphincter relaxation during swallowing. Characterized by its rarity, it affects an estimated 1 per 100,000 people with a prevalence of 10 per 100,000. Diagnosis primarily relies on high-resolution esophageal manometry (HREM), categorizing achalasia into three types based on motility patterns. Despite various treatment modalities—pharmacologic, endoscopic, and surgical—aiming to alleviate lower esophageal sphincter hypertonicity, restoration of normal peristalsis remains elusive. Pharmacologic approaches, limited in efficacy, are typically reserved for non-surgical candidates. Surgical interventions, including pneumatic dilatation, Heller myotomy, Dor fundoplication, and per-oral endoscopic myotomy (POEM), are frequently employed. Notably, Heller myotomy and fundoplication demonstrate superior long-term clinical outcomes. An evaluation spanning two decades (June 1999 - June 2019) involving 111 patients undergoing minimally invasive treatments—96 laparoscopic and 15 robotic—examined the effectiveness of laparoscopic Heller myotomy and Dor fundoplication. Patient demographics revealed a mean age of 49 years and a dysphagia duration averaging 96 months. Among those undergoing pH monitoring, 18 cases exhibited pathologic reflux out of 50 patients.

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a commonly performed bariatric surgery worldwide. However, one rare complication following LRYGB is the development of bezoars, which can lead to small bowel obstructions (SBO). We present a unique case of a patient who developed a gastric bezoar with subsequent migration to the biliopancreatic limb after One Anastomosis Gastric Bypass (OAGB) surgery. Case Report: A 65-year-old female with a history of OAGB surgery presented with acute weight loss and abdominal pain. Imaging studies revealed a bezoar in the duodenal diverticulum causing obstruction in the small bowel. An urgent laparoscopic intervention was performed to remove the bezoar and alleviate the obstruction. The patient experienced post-operative complications, including gastrostomy drainage and subsequent biliobezoar migration. Additional surgeries were required to address these complications. Conclusion: This case highlights the importance of recognizing and managing bezoars as a potential complication following bariatric surgery. Prompt diagnosis and appropriate surgical intervention are crucial to prevent complications and optimize patient outcomes.
