Intercostal abdominal hernia in the 11th intercostal space was identified in a leopard cat. Although mild leukopenia was found in laboratory examinations, no remarkable abnormality was revealed in medical imaging. To investigate abdominal organs, diagnostic laparoscopy was performed after hernia repair. In laparoscopic view, closure of the herniation site and a lesion with whitish discoloration in the liver (left medial lobe) were observed. Subsequently, laparoscopic liver biopsy was performed against the affected hepatic tissue. Histologically, the sample was diagnosed as mild hepatic lipidosis. Laparoscopy is considered useful for abdominal visceral examination and liver biopsy in a leopard cat patient.

When jaundice persists for more than 14 days postnatally, the early diagnosis of surgical jaundice is important for the prognosis in extrahepatic biliary atresia after draining procedure. The role of diagnostic laparoscopy to differenctiate medical causes of jaundice from biliary atresia is evaluated in this report. Four patients with prolonged jaundice have been included in this study. When the gallbladder was not visualized we proceeded to laparotomy. In patients with enlarged gallbladder visualized at laparoscopy, laparoscopic guided cholangiogram was performed, and laparoscopic liver biopsy was done for those who had a patent biliary tree. Two patients had small atretic gallbladder and underwent a Kasai hepato-portoenterostomy. One patients showed a patent gallbladder and common bile duct with atresia of the common hepatic and intrahepatic ducts, and they underwent a Kasai hepatic-portoenterostomy. One patient showed an enlarged gallbladder and laparoscopic-guided cholangiogram were normal. Laparoscopic liver biopsy was performed. There were no complications. Laparoscopy with laparoscopic-guided cholangiogram may be a valuable method in accurate and earlier diagnosis in an infant with prolonged jaundice.

Four dogs and two cats received laparoscopic or laparoscopic-assisted biopsy of abdominal organs for definite diagnosis of illness. Patients were presented with a chief complaint of acute or chronic vomiting excluding case 5 (seizure). Two patients needed the liver biopsy (case 1 and 5), and others did stomach and small intestine biopsy excluding case 2 (small intestine biopsy only). Surgical procedure was performed with modified standard methods. All patients recovered uneventfully and did not require any hospitalization without complications. Laparoscopic and laparoscopic-assisted biopsy could offer benefits of reduced incision length and rapid postoperative recovery.

A 10-year-old, 24.1 kg, intact female Siberian husky dog (case 1) and 11-year-old, 5.0 kg, intact male Shihtzu dog (case 2) presented with chief complaints of polydipsia, anorexia, vomiting and exercise intolerance (case 1) and stranguria (case 2). Splenic nodule (case 1) and mass (case 2) were identified in these patients through ultrasonographic examination. Laparoscopic splenectomy was conducted for the histopathologic evaluation. In addition, laparoscopic ovariohysterectomy, liver biopsy (case 1) and castration (case 2) were performed for treatment or diagnosis of primary symptoms. Under general anesthesia, 5 mm three-portal access laparoscopic splenectomy was performed using the Sonicision$^{TM}$ equipment. The dogs were rotated onto right lateral recumbency. The spleen was elevated using a fan or goldfinger retractor, which revealed the ventral aspect of the spleen. Resection of vessels was started at the caudal aspect of the spleen using the Sonicision$^{TM}$. The excised spleen was removed from the abdominal cavity using a 12 mm endo-bag via the enlarged instrument portal. There were no post-operative complications in either patient. Histopathologic diagnoses were splenic lymphoid hyperplasia (case 1) and splenic nodular hyperplasia (case 2). Based on our experience, laparoscopic splenectomy is sufficient to replace traditional splenectomy in small animal surgery. The use of the Sonicision$^{TM}$ could be a novel surgical technique for three-portal laparoscopic splenectomy, regardless of patient size.

Insulinoma, which arises from insulin-producing pancreatic beta cells, is a rare tumor in children. Only 5%-10% of insulinomas are malignant and undergo metastasis. We report a case of an 11-year-old girl who experienced hypoglycemia-related seizures induced by an insulinoma; after resection of the primary tumor, she developed hepatic focal nodular hyperplasia (FNH). Laboratory test results indicated marked hypoglycemia with hyperinsulinemia. Abdominal ultrasonography (US) and computed tomography results were normal; however, magnetic resonance imaging (MRI) showed a solid mass in the pancreatic tail. Therefore, laparoscopic distal pancreatectomy was performed. Two months after the surgery, an abdominal MRI revealed multiple nodular lesions in the liver. An US-guided liver biopsy was then performed, and histological examination revealed FNH without necrosis or mitotic activity. The patient has been free of hypoglycemia for 2 years, and recent MRI studies showed a decrease in the size of FNH lesions, without any evidence of metastasis. Even though no metastatic lesions are noted on imaging, close observation and follow-up imaging studies are required in a child with insulinoma that has malignant potential on histopathologic findings.

A 67 year old male at a regular checkup underwent esophagogastroduodenoscopy. On performing esophagogastroduodenoscopy, a lesion about 1.2 cm depressed was noted at the gastric angle. The pathology of the biopsy specimen revealed a well-differentiated adenocarcinoma. On performing an abdominal computed tomography (CT) scan & positron emission tomography-computed tomography (PET-CT) scan, no definite evidence of gastric wall thickening or mass lesion was found. However, lymph node enlargement was found in the left gastric and prepancreatic spaces. This patient underwent laparoscopic assisted distal gastrectomy and D2 lymph node dissection. On final examination, it was found out that the tumor had invaded the mucosal layer. The lymph node was a metastasized large cell neuroendocrine carcinoma with an unknown primary site. The patient refused chemotherapy. He opted to undergo a close followup. At the postoperative month 27, he had a focal hypermetabolic lesion in the left lobe of the liver that suggested metastasis on PET-CT scan. He refused to undergo an operation. He underwent a radiofrequency ablation.
