Anatomical recognition of dissection layers, nerves, vas deferens, and microvessels using artificial intelligence during transabdominal preperitoneal inguinal hernia repair.

Purpose: In laparoscopic inguinal hernia surgery, proper recognition of loose connective tissue, nerves, vas deferens, and microvessels is important to prevent postoperative complications, such as recurrence, pain, sexual dysfunction, and bleeding. EUREKA (Anaut Inc., Tokyo, Japan) is a system that uses artificial intelligence (AI) for anatomical recognition.

Experience with chemotherapy for postoperative metastases of adenosquamous carcinoma of the esophagogastric junction and pathological study of its development.

We report here a case of postoperative recurrent adenosquamous carcinoma (ASC) of the esophagogastric junction (EGJ) treated with S-1 therapy. A 79-year-old woman was diagnosed with carcinoma of the EGJ. Thoracoscopic subtotal esophagectomy was performed, and pathological examination revealed advanced ASC with lymph node metastasis.

[A Case of Advanced Esophagogastric Junction Adenocarcinoma with Enlarged Lymph Node Metastases of the Middle Mediastinum and Intraperitoneal That Exhibited pCR by Preoperative SOX Therapy].

A 79-year-old man was diagnosed with esophagogastric junction adenocarcinoma, cT3N3M0, cStage Ⅲ, including enlarged lymph node metastases(Bulky N)in the middle mediastinum and intraperitoneal. A total of 2 cycles of S-1 plus oxaliplatin(SOX)was administered. After neoadjuvant chemotherapy, the primary tumor and enlarged lymph nodes had greatly decreased in size.

Blunt pharyngeal trauma detected by ultrasound sonography: A case report.

Pharyngeal perforation related to blunt neck trauma is a rare clinical entity. Here in, we report a case of pharyngeal perforation secondary to minor blunt neck trauma. A 46 year old female was brought to our emergency room with neck pain.

Laparoscopic reduction and repair of a strangulated interparietal inguinal hernia.

An interparietal hernia is defined as a hernia in which the hernial sac lies between the tissue layers comprising the abdominal wall. A strangulated interparietal inguinal hernia without an external bulge is a rare cause of an acute abdomen and difficult to diagnose preoperatively. We report a patient with a history of a right inguinal hernia who presented with abdominal pain without inguinal bulging.

Superior mesenteric venous thrombosis after laparoscopic exploration for small bowel obstruction.

Mesenteric venous thrombosis is a rare cause of intestinal ischemia which is potentially life-threatening because it can lead to intestinal infarction. Mesenteric venous thrombosis rarely develops after abdominal surgery and is usually associated with coagulation disorders. Associated symptoms are generally subtle or nonspecific, often resulting in delayed diagnosis.

[Long-term survival of a patient with giant liver metastatic breast cancer treated with trastuzumab].

We report the long-term survival of a patient with metastatic breast cancer treated with trastuzumab and chemoendocrine therapy. The patient was a 60-year-old female. She underwent right mastectomy with axillary lymphadenectomy I c for advanced right breast cancer in 1999.
