Laparoscopic Resection for Rectal Cancer in a Centenarian: A Case Report Highlighting the Importance of Functional Independence over Chronological Age

Asahi Tokinaga, et al.

INTRODUCTION: Laparoscopic resection for rectal cancer in a centenarian is extraordinarily rare, with only a few cases of elective curative surgery reported worldwide. As the global population ages, the number of centenarians with malignancies is increasing; however, surgical intervention in this age group remains controversial due to frailty and limited physiological reserve.

Conversion Surgery for Alpha-Fetoprotein–Producing Esophagogastric Junction Cancer with Multiple Liver Metastases and Portal Vein Tumor Thrombus after Nivolumab Combination Chemotherapy: A Case Report and Literature Review

Masaaki Akai, et al.

INTRODUCTION: Alpha-fetoprotein–producing gastric cancer (AFPGC) is a rare subtype of gastric cancer associated with poor prognosis due to early liver metastasis. There have been limited reports on conversion surgery following nivolumab combination chemotherapy in cases of AFPGC with liver metastasis. Here, we present a case of alpha-fetoprotein–producing esophagogastric junction cancer (AFP-EGJC) successfully treated with this treatment.

Intratesticular Fetus in Fetu Arising from an Intra-Abdominal Undescended Right Testis: A Case Report

Fuminori Numano, et al.

INTRODUCTION: Fetus in fetu (FIF) is a rare congenital anomaly. The most common location of FIF is the retroperitoneum. FIF of testicular origin is extremely rare, with only 9 cases reported previously. We present a case of intratesticular FIF within an intra-abdominal undescended right testis and review previously reported cases to discuss the possibility of intratesticular FIF.

Evaluation of Remnant Esophageal Perfusion Using Indocyanine Green Fluorescence Imaging during Ivor Lewis Esophagectomy after Total Pharyngolaryngectomy: A Case Report

Shirou Kuwabara, et al.

INTRODUCTION: Head and neck cancer frequently coexists with synchronous or metachronous esophageal cancer, owing to shared carcinogenic exposures such as alcohol and tobacco use. In patients undergoing esophagectomy after total pharyngolaryngectomy (TPL), surgical reconstruction poses significant challenges due to dense adhesions and altered cervical anatomy. The McKeown procedure requires cervical manipulation, demanding careful preservation of the tracheal stoma and free jejunal graft blood supply. In contrast, the Ivor Lewis procedure eliminates the need for cervical maneuver but necessitates an intrathoracic anastomosis between the gastric conduit and the remnant esophagus. This raises concerns regarding potential ischemia of the remnant esophagus, particularly after prior TPL, in which proximal blood supply may be compromised. We report a case of successful robot-assisted Ivor Lewis esophagectomy after TPL, in which intraoperative indocyanine green (ICG) fluorescence imaging was used to confirm sufficient blood supply in the remnant esophagus and to ensure a safe anastomosis.

A Rare Case of Poorly Differentiated Lower Esophageal Cancer with Neuroendocrine Differentiation and α-Fetoprotein Production

Mamiko Takii, et al.

INTRODUCTION: Neuroendocrine differentiation and α-fetoprotein production (AFP) are 2 rarely reported features in poorly differentiated gastric carcinomas. We report an extremely rare case of esophageal carcinoma (EC) featuring both histologic types.

Fiber-Guided Red Light-Emitting Diode Localization of an Esophageal Blind End in Long-Gap Esophageal Atresia Surgery: A Case Report

Hiroki Kanamori, et al.

INTRODUCTION: Esophageal atresia (EA) Gross type A is a congenital malformation in which both the upper and lower esophagus have blind ends without a tracheoesophageal fistula. The gap between the segments is often long (long-gap EA), making intraoperative localization challenging. We report a case in which the lower esophageal blind end was readily localized using Tumguide (Otsuka Pharmaceutical Factory, Tokushima, Japan), a device that transmits biologically transparent red light from a light-emitting diode (LED) through an optical fiber.

Laparoscopic Repair of a Sciatic Hernia Using a Self-Fixating Mesh: A Case Report

Kimihiro Hattori, et al.

INTRODUCTION: A hernia that protrudes through the sciatic foramen is called a sciatic hernia and is classified as a pelvic hernia, although it is the rarest type. We aimed to report a case of elective laparoscopic repair of a sciatic hernia using a self-fixating mesh.

The Realization of a Remote Robotic Breast Surgery

Fujun Shi, et al.

INTRODUCTION: While remote telesurgery has advanced fields like urology and general surgery, its application in breast oncology remains unreported. We present a successful case of remote robotic nipple-sparing mastectomy (rNSM), which preliminarily confirms its technical feasibility and perioperative safety.

Solitary Hepatic Metastasis of Thymoma: A Case Report

Hiroshi Sakai, et al.

INTRODUCTION: Hepatic recurrence of thymomas is uncommon and its surgical treatment has rarely been reported. We report the case of a patient who underwent surgical resection for a solitary liver metastasis of a thymoma.

A Successfully Treated Case of Pediatric Traumatic Gastric Rupture Caused by Seat Belt Injury

Yumiko Tabata, et al.

INTRODUCTION: Gastrointestinal tract injury is estimated to occur in 0.9%–1% of blunt trauma cases, with gastric rupture occurring in approximately 3% of these cases. Blunt trauma injuries of the stomach are rare. In comparison to solid organ injuries, gastrointestinal tract injuries are less likely to be accompanied by hemorrhaging that can cause hemorrhagic shock, and the process is considered to be relatively slow.
