Introduction: Ileorectal fistulas following sigmoid colon vaginoplasty are rare. Reports on the management of the surgical complications of sex reassignment operations among transgender patients are few.
Presentation Of Case: A 40-year-old patient with a male-to-female sex identity disorder underwent sigmoid vaginoplasty for sex reassignment 4 months prior to presentation.
The present study aimed to investigate whether side-to-end anastomosis could provide an improved surgical outcome, such as lower anastomotic leakage rate, compared with end-to-end anastomosis, following anterior resection for rectal and rectosigmoid cancer. This retrospective study included 162 patients with rectal cancer who underwent elective anterior resection between January 2012 and October 2019 at a single institution. Patients with double cancers or colonic J-pouch were excluded.

Nine months later, his serum carcinoembryonic antigen (CEA) level had increased, and the diagnosis of recurrent peritoneal dissemination was made based on positron emission tomography/computed tomography (PET/CT) findings. Although systemic chemotherapy comprising S-1 and oxaliplatin (SOX) plus bevacizumab was initiated, severe diarrhea occurred on day 4 of the second cycle despite reduction in S-1 dose.

The treatment remains controversial and depends on institutional expertise. Although laparoscopic surgery is a good adaptation for the repair of ventral hernias, only a few cases have been reported in the literature.

Introduction: The lateral approach is the standard for laparoscopic splenectomy. However, when the modified Hassab's operation is performed laparoscopically, the patient is placed in the supine position and then the right semi-lateral or lateral decubitus position. Based on our experience with laparoscopic adrenalectomy and splenectomy, we laparoscopically performed the modified Hassab's operation with the patient in the right lateral decubitus position.

The objective of this article is to introduce the new technique and to examine whether the technique provides sufficient resistance to abdominal pressure.
Methods: We conducted two tests using a porcine model, a traction experiment and artificial pneumoperitoneum test.
Background/aims: This study was to examine the utility of a modified double-stapling end-to-end gastroduodenostomy method ('Tornado' anastomosis) compared to a method with an additional gastrotomy ('Anterior Incision' method) in laparoscopy-assisted distal gastrectomy.
Methodology: Forty-two patients with gastric cancer who underwent laparoscopy-assisted distal gastrectomy were analyzed retrospectively. Billroth-I using an additional gastrotomy was performed in 24 patients (AI group) and Billroth-I without an additional gastrotomy was performed in 18 (TOR group).
Non-occlusive mesenteric ischemia (NOMI), leading to intestinal gangrene without a demonstrable occlusion in the mesenteric artery, is a rare condition with extremely high mortality. We report a case of NOMI diagnosed preoperatively by computed tomography and treated successfully with surgery, assisted by indocyanine green (ICG) fluorescence in the HyperEye Medical System (HEMS), a new device that can simultaneously detect color and near-infrared rays under room light. This allowed for precise intraoperative evaluation of the mesenteric and bowel circulation.

Physical examination revealed anal stenosis associated with a circular mass arising in the anal canal. Histological examination of biopsy specimens confirmed a diagnosis of moderately differentiated squamous cell carcinoma.
View Article and Find Full Text PDFA 78-year-old Japanese man with a history of colon cancer was referred to our department of neurosurgery for the management of asymptomatic left chronic subdural hematoma (CSDH). He was receiving bevacizumab therapy for colon cancer, and the size of the CSDH increased or decreased depending on bevacizumab administration. Simple drainage was performed because of the risk of a critical increase in the size of CSDH during bevacizumab therapy, but since the CSDH was organized and firm, the drainage was insufficient.

On the other hand, in Europe, it was earlier that the first laparoscopic examination was tried in 1901 by Kelling. After that, laparoscopic surgery was developed by originating in a gynecologic surgery.

Purpose: This prospective study was conducted to clarify the association between the short-term outcome of laparoscopic colorectal surgery and visceral obesity (VO) based on waist circumference (WC).
Methods: WC and body mass index (BMI) were preoperatively measured in 98 consecutive patients with colorectal cancer undergoing laparoscopic surgery between June 2004 and February 2006. VO was defined as both BMI >or=25 kg/m2 and WC >or=85 cm in male patients, or WC >or=90 cm in female patients.
Background: Peroxisome proliferator-activated receptor-gamma (PPARgamma) is a member of the steroid receptor superfamily. Liganded PPARgamma can inhibit cancer cell proliferation. The in vitro and in vivo inhibitory effect of the synthetic ligands, ciglitazone (CGZ) and pioglitazone (PGZ), on human colon cancer was investigated.
View Article and Find Full Text PDFTissue factor (TF) is a transmembrane glycoprotein that plays roles in the blood coagulation and intracellular signaling pathways, and has also been suggested to modulate the biological behavior of cancer cells. In order to examine the clinicopathologic significance of TF expression in pancreatic ductal adenocarcinoma, TF expression was determined by immunohistochemistry using a newly raised anti-TF monoclonal antibody in 113 patients who had undergone surgical resection of pancreatic ductal adenocarcinoma. According to the incidence of tumor cell immunopositivity, patients were divided into "negative TF" (0%), "weak TF" (<25%), or "high TF" (25% or more) groups, which accounted for 11.
