Sonographically-guided Parasacrum Infrapiriformis Drainage of Deep Pelvic Abscesses: An Anatomical Safety Study Using SYNAPSE VINCENT.

Objectives: Deep pelvic abscesses are surrounded by the pelvic bones, bladder, gynecological organs, intestinal tract, and nerve and vascular systems, and are approached by various routes for drainage. The transgluteal approach is often performed under computed tomography guidance; however, if ultrasonography can be used to confirm the approach, it is considered more effective because it reduces radiation exposure and allows for real-time puncture under sonographic and fluoroscopic guidance.

Methods: This retrospective study was conducted at Tobata Kyoritsu Hospital (Fukuoka, Japan) between April 1, 2021, and December 31, 2022.

[Synchronous Lung Metastasis and Hilar Lymph Node Metastasis from Rectal Cancer-A Case Report].

A 64-year-old male was referred to our hospital with both advanced rectal cancer and lung tumor with swollen lymph nodes in the lung hilum.

Introduction: Laparoscopic low anterior resection (L-LAR) has become widely accepted for the treatment of rectal cancer. However, little is known about the superiority of L-LAR in a real-world setting (including low-volume hospitals) and the association between the short-term outcomes and hospital volume focusing on L-LAR.

Methods: This is a retrospective cohort study.

[A Case Report of Lateral Paracecal Hernia Treated with Single Port Surgery].

An 86-year-old female hospitalized for right femoral fracture complained of a sudden abdominal pain and vomited. Contrast-enhanced computed tomography (CECT) of the abdomen showed an ileal closed loop with dilatation of the oral side intestine. She was diagnosed with a bowel obstruction due to a paracecal hernia with incarceration and underwent an emergency operation.

The prognostic significance of the expression of monocarboxylate transporter 4 in patients with right- or left-sided colorectal cancer.

Aim: Monocarboxylate transporter 4 (MCT4) is a proton pump that exchanges lactate through the plasma membrane. The present study investigated the clinical significance of the expression of MCT4 in patients with right- or left-sided colorectal cancer (CRC).

Methods: Surgical specimens from 237 CRC patients were immunohistochemically stained with polyclonal anti-MCT4 antibodies.

Prognostic Significance of Mitochondrial Transcription Factor A Expression in Patients with Right- or Left-sided Colorectal Cancer.

Background/aim: Mitochondrial transcription factor A (mtTFA) is necessary for both the transcription and maintenance of mitochondrial DNA (mtDNA). The present study investigated the clinical significance of mtTFA in patients with right- and left-sided colorectal cancer (CRC).

Patients And Methods: Surgical specimens from 237 CRC patients were immunohistochemically stained with polyclonal anti-mtTFA antibody.

Novel technique of abdominal wall nerve block for laparoscopic colostomy: Rectus sheath block with transperitoneal approach.

A 62-year-old man who had acute rectal obstruction due to a large rectal cancer is presented. He underwent emergency laparoscopic colostomy. We used the laparoscopic puncture needle to inject analgesia with the novel transperitoneal approach.

Transperitoneal rectus sheath block and transversus abdominis plane block for laparoscopic inguinal hernia repair: A novel approach.

Introduction: A laparoscopic approach for inguinal hernia repair is now considered the gold standard. Laparoscopic surgery is associated with a significant reduction in postoperative pain. Epidural analgesia cannot be used in patients with perioperative anticoagulant therapy because of complications such as epidural hematoma.

A Case of Advanced Descending Colon Cancer in an Adult Patient with Intestinal Malrotation.

This report presents an operative case of advanced descending colon cancer in an adult patient with intestinal malrotation. A 63-year-old Japanese male was suffering from left side abdominal pain, abdominal distension, and constipation. An endoscopic examination revealed an advanced tumor in the descending colon.

Laparoscopic cecal cancer resection in a patient with a ventriculoperitoneal shunt: A case report.

Introduction: The presence of a ventriculoperitoneal shunt has been considered to be a contraindication for laparoscopic surgery till date; however, laparoscopic cholecystectomy was recently reported as safe for patients with this shunt.

Presentation Of Case: We present the first case, to the best of our knowledge, of laparoscopic colectomy for cecal cancer in a patient with a ventriculoperitoneal shunt. A 59-year-old woman with a ventriculoperitoneal shunt for hydrocephalus was referred to our hospital with cecal cancer.

[Evaluation of palonosetron for the prevention of nausea and vomiting induced by colon cancer chemotherapy].

Chemotherapy-induced nausea and vomiting(CINV)is one of the side effects causing significant psychological and physical suffering in patients receiving chemotherapy. First-generation 5-HT3 receptor antagonists(ondansetron, granisetron and ramosetron)are available, but some patients are still not treated adequately. Palonosetron is a second-generation 5-HT3 receptor antagonist with a prolonged duration of action and a higher receptor binding affinity than first-generation agents.

Development of perianal ulcer as a result of acute fulminant amoebic colitis.

We report a case of acute fulminant amoebic colitis that resulted in the development of a perianal ulcer in a 29-year-old Japanese homosexual man with acquired immunodeficiency syndrome (AIDS). The patient was admitted to our hospital with a persistent perianal abscess that was refractory to antibiotic therapy administered at another hospital. On admission, we observed a giant ulcer in the perianal region.
