Article Synopsis
  • Complete surgical resection with negative margins is crucial for treating rectal cancer, but local recurrence can be challenging; a new surgical technique was developed to resect the pubic arch and ischial bone for recurrent cases.
  • A case study demonstrated this technique on a patient with a fourth local recurrence where the tumor invaded the pubic arch; an osteotomy successfully removed the affected bones while ensuring no cancer cells were present in the margins.
  • This innovative approach may significantly aid in achieving complete resection in patients with recurrent rectal cancer, improving treatment outcomes.

Case Presentation: A 61-year-old female was referred to our hospital with a neoplastic lesion in the duodenum. Computed tomography with contrast enhancement revealed a 10-mm tumor in the duodenum. Upper gastrointestinal endoscopy revealed a submucosal tumor-like lesion in the descending part of the duodenum.

Background/aim: Stoma prolapse is a common complication in the late phase after stoma creation. With advances in chemotherapy, a double-orifice colostomy or ileostomy and chemotherapy are used to treat primary unresectable colorectal cancer. Preoperative therapy with a double-orifice colostomy or ileostomy is performed to aid primary colorectal cancer miniaturization.

Background: Liposarcoma originating from peripancreatic fat tissue is extremely rare. This case report presents a surgical case of a giant liposarcoma originating from peripancreatic fat tissue with origin identification using 3-Dimensional Computed Tomography Angiography (3D-CTA).

Case Presentation: A 59-year-old female was referred to our hospital with a giant abdominal tumor.

Ureteroenteric anastomotic strictures (UEAS) are typical complications after creating an ileal conduit for total pelvic exenteration (TPE) of rectal tumors. We report the ileal conduit for reconstruction in three patients, in the age-range of 47-73 years. Case 1 was when a left-sided UEAS had sufficient length of ureter for anastomosis, Case 2 was a right-sided UEAS with sufficient length of ureter for anastomosis, and Case 3 was a left-sided UEAS with insufficient length of ureter for anastomosis.

The frequency of resection for the recurrence of colorectal cancer has not been investigated in previous studies. Likewise, the related postoperative complications and the limit for indicating surgical resection has not been reported. Herein, we reported the complications of a highly frequent surgical approach for rectal cancer recurrence, i.

Article Synopsis
  • Hyperchloremic metabolic acidosis is a rare complication following total pelvic exenteration (TPE), often linked to urinary diversion via an ileal conduit.
  • A new technique for retrograde catheterization of a ureteral stent into the ileal conduit was developed to address this issue, collaborating between endoscopists and radiologists.
  • After implementing this method on a 70-year-old patient with complications post-TPE, his condition significantly improved, suggesting the technique’s effectiveness and potential for broader application.

Article Synopsis
  • - The study examined the surgical outcomes of total pelvic exenteration combined with sacral resection for rectal cancer, focusing on how the level of sacral resection affects short-term results.
  • - Data from 20 cases indicated that patients with recurrent cancers experienced significantly higher complication rates, particularly with "Upper" sacral resections compared to "Lower" resections.
  • - The findings suggest that patients undergoing "Upper" sacral resections for recurrent rectal cancer are at a greater risk for complications, emphasizing the necessity for careful postoperative monitoring.

Introduction: Adult intussusception is a rare condition with a pathological lead point. Intraoperative reduction of adult intussusception can eliminate the need for extensive or invasive resection. We safely performed a manual laparoscopy-assisted intraoperative reduction that allowed functional preservation of tissue.

Purpose: It has been suggested that inflammatory mediators such as cytokines released during intestinal ischemia and reperfusion increase permeability in the lungs. Cytokines exist at concentrations several hundred times higher at the site of inflammation than in the blood. When absorbed, the locally produced cytokines may affect multiple remote organs.
