Surgical management of primary undifferentiated pleomorphic sarcoma of the rectum: a case report and review of the literature.

Background: Undifferentiated pleomorphic sarcoma (UPS) is a malignant soft tissue tumor that has been reclassified from malignant fibrous histiocytoma with the development of the pathological diagnosis. It principally occurs in the extremities but rarely occurs in the rectum. We herein report a rare case of UPS arising in the rectum.

[A case of primary mesenteric schwannoma with secondary ossification].

Schwannoma is a tumor that usually originates soft tissue peripheral nerves. Primary mesenteric schwannomas are rare, and furthermore, there are few reports of this with secondary ossification, which is extremely rare. Herein we report a case of primary mesenteric schwannoma with secondary ossification in a 46-year-old Japanese woman with recurrent postprandial abdominal pain and weight loss.

Colonoscopy-assisted percutaneous sigmoidopexy: a novel, simple, safe, and efficient treatment for inoperable sigmoid volvulus (with videos).

Background And Aims: Many patients with sigmoid volvulus are old with co-morbidities, making elective surgery prohibitive. Colonoscopic management is often successful but volvulus often recurs. We devised a method of colonoscopy-assisted percutaneous sigmoidopexy as an alternative method to prevent recurrence of sigmoid volvulus.

Double Percutaneous Transesophageal Gastrotubing for Gastric Cancer: A Pilot Study.

Background: The management of gastric cancer causing gastric outlet obstruction and dilatation must include decompression of the stomach and intravenous nutrition. Percutaneous transesophageal gastrotubing (PTEG) is an effective technique for either gastric decompression or enteral nutrition. Here, we investigated the efficacy and safety of double PTEG (dPTEG), that is, using PTEG for both purposes simultaneously, in patients with gastric cancer.

Endoscopic submucosal dissection for the diagnosis and therapy of pedunculated gastric cancer with prolapse into the duodenal bulb: A case report.

Introduction: Preoperative diagnosis of gastric cancer invasion is not always sufficiently accurate. Diagnostic endoscopic submucosal dissection (ESD) can be performed for the purpose of accurate decision making and to avoid partial treatment vs aggressive over-treatment. We present a patient with the gastric cancer with indeterminate pre-operative diagnosis for depth of the invasion.

Optimal timing of preoperative indocyanine green administration for fluorescent cholangiography during laparoscopic cholecystectomy using the PINPOINT® Endoscopic Fluorescence Imaging System.

Introduction: The PINPOINT® Endoscopic Fluorescence Imaging System (Novadaq, Mississauga, Canada) allows surgeons to visualize the bile ducts during laparoscopic cholecystectomy. Surgeons can continue operation while confirming the bile ducts' fluorescence with a bright-field/color image. However, strong fluorescence of the liver can interfere with the surgery.

Prophylactic retention suture for surgical site infection: a retrospective cohort study.

Background: Surgical site infection (SSI) is a common complication of gastrointestinal surgery. Because retention suture is known to prevent abdominal wound dehiscence, it is only considered indicated in high-risk patients. At present, there are no clear indications for retention suture.

Stomaplasty with pannicuectomy in an obese patient with stomal retraction: A case report.

Introduction: Stomal retraction is a common complication following stoma formation. A repeat surgical procedure for stomal revision is an invasive treatment that is often required as a result.

Case Presentation: An 81-year-old woman with obstructive rectal carcinoma and perforative peritonitis underwent an emergent anterior resection and colostomy (Hartmann's operation).

Crus incision without repair is a risk factor for esophageal hiatal hernia after laparoscopic total gastrectomy: a retrospective cohort study.

Background: Although postoperative esophageal hiatal hernia (EHH) is primarily considered a post-operative complication of esophagectomy, it is also a rare post-operative complication of laparoscopic total gastrectomy (LTG), with a reported incidence rate of 0.5 %. The purpose of this study is to analyze the incidence, clinical features, and prevention of EHH following LTG for gastric cancer.

New technique for treating abdominal surgical site infection using CT woundgraphy and NPWT: A case report.

Introduction: Negative pressure wound therapy (NPWT) for abdominal surgical site infection (SSI) is becoming increasingly common, although enterocutaneous fistula (ECF) has been reported as a complication. To avoid ECF, we used computed tomography (CT) woundgraphy to evaluate the relationship between the wound and the intestine, and then safely treated the abdominal SSI with NPWT.

Case Presentation: Following a laparoscopic intersphincteric resection for low rectal neuroendocrine tumor and covering ileostomy, a 59-year-old woman underwent stoma closure.
