Bladder invasion by appendiceal cancer resulting in a vesico-appendiceal fistula is an uncommon occurrence. Both radical tumor removal and functional preservation of the bladder are desirable in the surgical treatment of this disease, and there are few reports on detailed surgical methods. Here, we describe a case of primary appendiceal mucinous carcinoma with bladder invasion treated with robotic laparoscopy and endoscopy cooperative surgery (RECS).

Here, we described the cervical-first approach in thoracoscopic esophagectomy for an esophageal cancer patient with ARSA using the intraoperative nerve monitoring (IONM) system. First, a left cervical procedure proceeded to expose the left vagus nerve to attach the APS electrode of the IONM system, and the left cervical paraesophageal lymph nodes was dissected separately.

This study aimed to validate the new classification and determine the effect of stage migration and vice versa on the prognosis of each pathological stage due to these changes.
Materials And Methods: A total of 1,754 patients with surgically resected lung cancer were included.
Background: In breast reconstruction using the abdominal perforator flap, if the flap capacity is too large, secondary revision procedures can be performed to reduce flap volume and reconstruct the inframammary fold (IMF). We examined the various revision methods and cosmetic results.
Methods: This study included 28 patients who underwent secondary revision among 216 patients who had breast reconstruction using the abdominal perforator flap between April 2012 and March 2019.
Background: Atrial fibrillation (AF) and heart failure (HF) often coexist, leading to increased mortality. A cryoballoon-based approach is a potential treatment for patients with HF because of its safety and efficacy.
Objectives: The authors sought to evaluate the optimal timing of cryoballoon ablation after the first clinical diagnosis of AF and its prognosis for patients with HF.
Protein phosphorylation is a crucial process in various cellular functions, and its irregularities have been implicated in several diseases, including cancer. Antibodies are commonly employed to detect protein phosphorylation in research. However, unlike the extensive studies on recognition mechanisms of the phosphate group by proteins such as kinases and phosphatases, only a few studies have explored antibody mechanisms.

Methods: Eight trainees and 4 faculty surgeons were enrolled. Their right upper lobe sleeve reconstruction procedures were scored by 2 senior surgeons in a blinded fashion on a 5-point Likert scale on the following: airway wall tear, reapplied ligatures, reapplied needles, needle entry and exit, anastomotic bite, and caliber adjustment (full score: 30).
Background: The appropriate extent of hilar lymph node (LN) dissection in segmentectomy for lung cancer has not yet been fully investigated. Herein, we assessed the patterns of LN metastasis using network analyses.
Methods: Patients with nodal metastases of non-small-cell lung cancer measuring ≤30 mm in diameter who underwent anatomical resection were included.

Background: Facial sensory nerves play vital roles in daily functions like self-protection, facial expressions, speaking, and eating. Severing the infraorbital nerve (ION) during partial maxillectomy via the Weber-Ferguson incision can lead to sensory disturbances. This study presents immediate ION reconstruction using artificial nerve conduits and its short-term outcomes.
View Article and Find Full Text PDFBackground And Objectives: A recent Japanese phase three clinical trial for lung cancer suggested a possible advantage of segmentectomy over lobectomy in terms of death from other diseases. This study aimed to compare the risk of death from other diseases based on surgical procedures in lung cancer patients without recurrence.
Methods: We retrospectively reviewed 2121 patients without disease recurrence after curative resection for lung cancer at our institution.
Living donor liver transplantation (LT) and deceased donor split-LT often result in congestion within liver grafts. The regenerative process and function of congested areas, especially graft congestion associated with LT, are not well understood. Therefore, we created new rat models with congested areas in partially resected livers and orthotopically transplanted these livers into syngeneic rats to observe liver regeneration and function in congested areas.
View Article and Find Full Text PDFChildren with intestinal failure suffer liver damage associated with parenteral nutrition: a condition known as intestinal failure-associated liver disease (IFALD), which requires transplantation of both liver and intestine. In many countries, simultaneous transplantation of these two organs is performed using grafts from a deceased donor, but there have been no such cases in Japan, and the details of the procedure are not clear. Recently, we performed simultaneous split liver and intestinal transplantation in two premature infants with IFALD, using organs from identical deceased donors and achieved good results.

We investigated whether the poor outcomes of LDLT for PALF persisted in the contemporary transplant era.
Methods: We analyzed 193 patients who underwent LDLT between December 2000 and December 2020.
We developed a surgical support system that visualises important microanatomies using artificial intelligence (AI). This study evaluated its accuracy in recognising the thoracic nerves during lung cancer surgery. Recognition models were created with deep learning using images precisely annotated for nerves.

Trueperella pyogenes (T. pyogenes) causes pneumonia in cattle and is involved in secondary infections following viral infections.
View Article and Find Full Text PDFBackground: The indication of living donor liver retransplantation (re-LDLT) for retransplant candidates with chronic allograft failure (CAF) is increasing because of the high mortality rate of patients on the waiting list. However, evidence supporting re-LDLT for CAF remains scarce because of technical difficulties. We aimed to examine the feasibility based on our significant case experience.

We report a LAMN surgical case whose appendiceal tumor penetrated the sigmoid colon wall. An 87-year-old man was referred for endoscopic resection (ER) of a colon polyp.

Unlabelled: WHAT IS KNOWN ON THE SUBJECT?: Recovery-oriented practices in community-based mental health services are of increasing importance. The recovery journey of individuals with mental illness starts with a sense of agency, and a therapeutic relationship with the providers who support them is a prerequisite. In Japan, the construction of community-based integrated care systems for individuals with mental illness is positioned as a priority health issue, with communication with familiar individuals being particularly important for recovery in Japanese and Asian cultures.
