Osteosarcoma of the hyoid bone in a cat.

Case Summary: A 10-year-old male neutered Abyssinian cat was presented with the chief complaint of a right pharyngeal mass. On palpation, the mass was easily palpable; it appeared well demarcated and mobile, and oval in shape. Radiographic examination showed a radiopaque pharyngeal mass, which was revealed to be a well-demarcated mass lesion with a radiopaque marginal area on CT examination.

Comparison of Three Clinical Trials of Preoperative Predictors for Complicated Appendicitis.

Background/aim: We previously reported three items that preoperatively predicted complicated appendicitis (body temperature, C-reactive protein, and fluid retention around the appendix). In this study, we aimed to compare other predictors to confirm the usefulness of our predictors with those of previous reports on the items as predictors of complicated appendicitis preoperatively (criteria A which consist of 8 items, criteria B which consist of 7 items).

Patients And Methods: We retrospectively evaluated 417 adult patients who underwent surgery for acute appendicitis between January 2013 and December 2019 and compared our items with criteria A and criteria B according to the results of the area under the receiver operating characteristic curve (AUC), homogeneity, discriminatory ability, and Akaike information criterion (AIC).

Background: Spontaneous rupture of a hemorrhagic hepatic cyst is extremely rare. There is no standard treatment recommended for this condition. We report two cases of hemorrhagic hepatic cysts that spontaneously ruptured and were successfully treated with laparoscopic deroofing.

Laparoscopic repair of sciatic hernia recognizing the ureterohypogastric nerve fascia and vesicohypogastric fascia: a case report.

Background: Sciatic hernias are rare pelvic floor hernias that occur through the sciatic foramen and often present as abdominal or pelvic pain, particularly in women. Historically, they were repaired using an open approach, with limited reports on their laparoscopic treatment.

Case Presentation: Here we present the case of an 85-year-old woman who had repeated abdominal pain and was referred to our hospital for sciatic hernia surgery after conservative treatment.

Mixed neuroendocrine non-neuroendocrine neoplasm: a case report and review.

Mixed neuroendocrine non-neuroendocrine neoplasm (MiNEN) of the pancreas is a rare entity, and obtaining a preoperative diagnosis is difficult. We present a 70-year-old man in whom the possibility of MiNEN was successfully discovered preoperatively by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). Immunostaining revealed positive results for the neuroendocrine markers chromogranin A and synaptophysin.

Postoperative oral energy and protein intakes for an enhanced recovery after surgery program incorporating early enteral nutrition for pancreaticoduodenectomy: A retrospective study.

Background: Although postoperative early oral feeding in the enhanced recovery after surgery (ERAS) program for pancreaticoduodenectomy (PD) is deemed safe, the assessment of oral intakes has been insufficient. This study aimed to investigate postoperative oral intakes and the effectiveness of an ERAS program incorporating early enteral nutrition (EN).

Methods: In total, 203 patients with PD were enrolled retrospectively.

Retroperitoneal Bronchogenic Cyst Resected by Single-Incision Laparoscopic Surgery in an Adolescent Female: A Case Report.

A 16-y-old Japanese female was referred to our hospital with a suspicion of infected retroperitoneal cyst. Abdominal CT MRI revealed a 38-mm diameter retroperitoneal cyst under the left diaphragm. Because a retroperitoneal bronchogenic cyst was suspected, total resection was planned.

A lymphoepithelial cyst in the pancreatic accessory spleen: A case report.

We present the first report of a lymphoepithelial cyst. As additional cases will likely be encountered in the future, our study sets the precedent for future research.

Intussusception caused by small intestine metastasis of malignant pleural mesothelioma: a case report.

Malignant pleural mesothelioma (MPM) is an aggressive form of malignant tumor that originates in the pleural mesothelioma and presents as a local disease in the affected hemithorax. Small intestine metastasis is a rare complication. Herein, the case of a patient with jejunal intussusception caused by small intestine metastasis of MPM has been reported.

Perforation of the descending colon diverticulum in a patient following recovery from severe COVID-19 pneumonia: a case report.

The outcome of surgery in patients who have recovered from severe coronavirus disease 2019 (COVID-19) is unknown. Herein, we present a case of an emergency operation for acute pan-peritonitis due to perforation of the descending colon diverticulum in a patient who recovered from severe COVID-19 pneumonia. A 59-year-old man, who had recovered from severe COVID-19 pneumonia ~6 months previously, developed acute pan-peritonitis due to perforation of a diverticulum in the descending colon.

Management of acute cholecystitis in patient with cyclic neutropenia: a case report.

Background: Cyclic neutropenia is a disease that causes a neutropenic decrease in peripheral blood in a cycle of about 21 days. It is a rare hereditary disorder with an estimated incidence of 0.5-1 cases per million population.

Capecitabine Plus Bevacizumab for Cardiac Metastasis of Sigmoid Colon Cancer: Case Report and Literature Review.

Background/aim: Right ventricular cardiac metastasis from colorectal cancer (CRC) is rare and clinically silent. There is no standardised treatment. To date, only twelve cases have been reported in the literature.

Laparoscopic repair of traumatic diaphragmatic hernia with colon incarceration: A case report.

Traumatic diaphragmatic hernia is a serious complication of blunt trauma to the abdomen or thorax. Although traumatic diaphragmatic hernia is treated with surgical repair, a laparoscopic approach is infrequently employed. Here we present the case of a 66-year-old man with a bruise on the left side of his back.

Step-up approach combined with negative pressure wound therapy for the treatment of severe necrotizing pancreatitis: a case report.

A step-up approach and continuous drainage using NPWT was an effective strategy for the treatment of severe necrotizing pancreatitis. A 62-year-old woman developed severe necrotizing pancreatitis after endoscopic retrograde cholangiopancreatography, extending from the left anterior pararenal space to the interior renal pole. Endoscopic transluminal drainage and percutaneous catheter drainage were unsuccessful in controlling the disease.
