  • Cryptococcus neoformans infection usually occurs in patients with advanced human immunodeficiency virus (HIV) infection or with a CD4 T lymphocyte count of <100 cells/µL. Pulmonary and central nervous system infections are the most frequently encountered forms of cryptococcosis; however, colonic cryptococcosis is uncommon. We describe the case of a 41-year-old antiretroviral-naïve man with HIV infection diagnosed eight years prior and intermittent diarrhea for 4 months who presented to the emergency department with a 1-day history of low-grade fever and confusion. Brain magnetic resonance imaging and cerebrospinal fluid analysis revealed normal results; however, he was diagnosed with Pneumocystis jirovecii pneumonia based on chest computed tomography and bronchoalveolar lavage analysis. Trimethoprim-sulfamethoxazole administration was initiated followed by antiretroviral treatment. Although his condition gradually improved, he developed fever and abdominal discomfort, and the diarrhea worsened. Endoscopy revealed a small ulcer in the distal transverse colon. Histopathological examination of a colon tissue sample revealed cryptococcal infection. He improved substantially during liposomal amphotericin B and fluconazole treatment. We encountered a rare case of colonic cryptococcosis that caused chronic diarrhea in a patient with advanced HIV infection. Colonic cryptococcosis should be considered when patients with acquired immune deficiency syndrome present with gastrointestinal symptoms.

  • Diaphragmatic reconstruction is required for extensive diaphragmatic defects associated with tumor resection. Methods using artificial mesh and autologous tissues, such as pedicled flaps, have been reported predominantly for diaphragmatic reconstruction. We present the case of a 61-year-old woman who presented with a 14×13×12 cm tumor in the abdominal cavity of the upper left abdomen on computed tomography. The diaphragm defect measuring 12×7 cm that occurred during excision of the malignant tumor was reconstructed using the rectus abdominis muscle and fascial flap. The flap has vertical and horizontal vascular axes; therefore, blood flow is stable. It also has the advantage of increasing the range of motion and reducing twisting of the vascular pedicles. Fascial flap does not require processing such as thinning and can be used during suture fixation. This procedure, which has rarely been reported so far, has many advantages and may be a useful option for diaphragm reconstruction.

  • The vascular anatomy of the deep inferior epigastric artery perforator (DIEP) flap has been well studied in the planning for autologous breast reconstruction. Preoperative imaging with computed tomography angiography (CTA) provides accurate assessment of this vascular anatomy, which varies widely across patients. Several papers to date have described their encounter with an anomalous "epiperitoneal" or "peritoneo-cutaneous" perforator during flap harvest, a perforator that pierces the posterior rectus sheath from a peritoneal origin, to traverse rectus abdominis and supply the DIEP flap integument. In the course of over 3,000 CTA assessments of the vascular anatomy of the abdominal wall, we have encountered dominant peritoneo-cutaneous perforators in 1% of cases, and smaller perforators seen in many more cases, approaching 5% of cases. With increasing sensitivity of imaging, we also describe a unique case of multiple large bilateral peritoneo-cutaneous perforators, and present these findings in the context of DIEP flap harvest. It is critical to recognize these peritoneo-cutaneous perforators preoperatively to avoid mistaking them for a DIEP during the raising of a DIEP flap. The routine use of preoperative CTA enables the safe identification of individual vascular anatomy, including significant peritoneo-cutaneous perforators.

  • Trauma remains a significant healthcare burden, causing over five million yearly fatalities. Notably, the liver is a frequently injured solid organ in abdominal trauma, especially in patients under 40 years. It becomes even more critical given that uncontrolled hemorrhage linked to liver trauma can have mortality rates ranging from 10% to 50%. Liver injuries, mainly resulting from blunt trauma such as motor vehicle accidents, are traditionally classified using the American Association for the Surgery of Trauma grading scale. However, recent developments have introduced the World Society of Emergency Surgery classification, which considers the patient's physiological status. The diagnostic approach often involves multiphase computed tomography (CT). Still, newer methods like split-bolus single-pass CT and contrast-enhanced ultrasound (CEUS) aim to reduce radiation exposure. Concerning management, nonoperative strategies have emerged as the gold standard, especially for hemodynamically stable patients. Incorporating angiography with embolization has also been beneficial, with success rates reported between 80% and 97%. However, it is essential to identify the specific source of bleeding for effective embolization. Given the severity of liver trauma and its potential complications, innovations in diagnostic and therapeutic approaches have been pivotal. While CT remains a primary diagnostic tool, methods like CEUS offer safer alternatives. Moreover, nonoperative management, especially when combined with angiography and embolization, has demonstrated notable success. Still, the healthcare community must remain vigilant to complications and continuously seek improvements in trauma care.

  • Gastric wall abscess, a localized form of phlegmonous gastritis, is a rare complication of endoscopic resection. We report the first case of gastric wall abscess developing after endoscopic submucosal dissection in Korea. A 72-year-old woman visited our clinic to receive treatment for gastric adenoma. The patient successfully underwent endoscopic submucosal dissection with no complications. The final diagnosis was well-differentiated tubular adenocarcinoma. We performed follow-up endoscopy 10 weeks later and found a large subepithelial lesion on the posterior wall of the gastric antrum. Abdominal computed tomography revealed hypodense wall thickening and a 5 cm heterogenous multilobular mass in the submucosal layer of the gastric antrum. Submucosal invasion with mucin-producing adenocarcinomas could therefore not be excluded. The patient agreed to undergo additional gastrectomy due to the possibility of a highly malignant lesion. The final diagnosis was acute suppurative inflammation with the formation of multiple abscesses in the mural layers and omentum. The patient was discharged with no complications.

  • A 50-year-old male presented gradually growing pancreatic body mass. An abdominal computed tomography showed a 9.9-cm mass, larger than the 8.9-cm mass one year ago. As the patient did not have complaints for any symptomatic problems, the gastroenterologist decided to check it with regular follow-up. However, as the tumor grew faster than expected, the patient was recommended for surgical resection. Laparoscopic pylorus preserving pancreaticoduodenectomy was done. Since the tumor abutted to the superior mesenteric vein and the portal vein, wedge resection of vessel was inevitable. Pathology was serous cystadenoma. The patient was discharged without postoperative complications. Herein, we report this case with asymptomatic large serous cystic neoplasm treated by laparoscopic approach. The appropriateness of current guidelines for surgery in serous cystic neoplasm is also discussed.

  • Iatrogenic perforations are severe complications of gastrointestinal endoscopy; therefore, their management should be adequately planned. A 77-year-old man with a history of diverticulosis underwent a colonoscopy for anemia. During the procedure, an iatrogenic perforation occurred suddenly in the sigmoid colon, near a severe angle among the numerous diverticula. Through-the-scope clips were immediately applied to treat it and close mucosal edges. Laboratory tests showed increased levels of inflammation and infection, and although there were no complaints of abdominal pain, the patient had an extremely distended abdomen. A multidisciplinary board began management based on a conservative approach. Pneumoperitoneum was treated with computed tomography-assisted drainage. After 72 hours, his intestinal canalization and laboratory tests were normal. Though this adverse event is rare, a multidisciplinary board should be promptly gathered upon occurrence, even if the patient appears clinically stable, to consider a conservative approach and avoid surgical treatment.

  • Patients with symptomatic gastrointestinal stromal tumor (GIST) typically present with gastrointestinal bleeding and abdominal pain. This report presents an unusual case of fundic GIST complicated by gastroduodenal intussusception, manifesting as acute pancreatitis. The patient presented with epigastric pain and pancreatic enzyme elevation; thus, he was diagnosed with acute pancreatitis. Computed tomography showed evidence of pancreatitis and a 4×4.7 cm well-defined hyperdense lesion in the 2nd part of the duodenum, compressing the pancreatic head and pancreatic duct. Esophagogastroduodenoscopy revealed invagination of the gastric folds into the duodenum, causing pyloric canal blockage consistent with gastroduodenal intussusception. Spontaneous reduction of the lesion during endoscopy revealed a 4 cm pedunculated subepithelial mass with central ulceration originating from the gastric fundus. Endoscopic ultrasound demonstrated a heterogeneous hypoechoic lesion originating from the 4th layer of the gastric wall. Laparoscopic-endoscopic intragastric wedge resection of the fundic lesion was subsequently performed, and surgical histology confirmed GIST.
