Intestinal transplant (IT) is one of the least common forms of organ transplant but is increasing both in volume of cases and number of centers performing intestinal transplants, with the busiest centers in North America and Europe. IT can be performed in isolation or as part of a multivisceral transplant (MVT). Intestinal failure either in the form of short gut syndrome or functional bowel problems is the primary indication for IT. The normal post-surgical anatomy can be variable due to both recipient anatomy in regard to amount of residual bowel and status of native vasculature as well as whether the transplant is isolated or part of an multivisceral transplant...

BACKGROUND: In view of the rarity of vaginal agenesis, malignancy arising in the neovagina is extremely rare. CASE PRESENTATION: Here, we report a 76-year-old female with an adenocarcinoma arising in the sigmoid colon neovagina which was constructed 53 years ago for congenital vaginal agenesis. Vaginal endoscopy to examine vaginal bleeding revealed a protruding lesion occupying three quarters of the lumen in the vicinity of anastomosis of the residual vagina and sigmoid colon...

Colorectal cancer is the third most common malignant tumor among men, and the second most common malignant tumor among women worldwide. As one of the most common malignant tumor, colorectal cancer has a great threat to the health of people. Although the development of radiotherapy and chemotherapy could improve the prognosis of colorectal cancer, surgery, the complete resection of the tumor, remains the only chance for the cure of this disease. Over the past hundred years, surgical oncology went in the direction of protecting organ function and improving quality of life...

Dispite continual improvements in diagnostic and management techniques, anastomotic leak (AL) remains one of the most devastating consequences of rectal cancer surgery. Recently, many investigations have attempted to identify the risk factors and established risk model to predict and prevent anastomotic leakage after low anterior resection. The distance between the lower edge of rectal cancer and the anal verge measured by magnetic resonance imaging was demonstrated as one of the independent risk factors associated with AL...

BACKGROUND: Decreasing anastomotic leak rates remain a major goal in colorectal surgery. Assessing intraoperative perfusion by indocyanine green (ICG) with near-infrared (NIR) visualization may assist in selection of intestinal transection level and subsequent anastomotic vascular sufficiency. This study examined the use of NIR-ICG imaging in colorectal surgery. METHODS: This was a prospective phase II study (NCT02459405) of non-selected patients undergoing any elective colorectal operation with anastomosis over a 3-year interval in three tertiary hospitals...

BACKGROUND: Selective digestive decontamination is commonly used to decrease lumenal bacterial flora. Preoperative bowel decontamination may be associated with a lower wound infection rate but has not been shown to decrease risk of intra-abdominal abscess or lower leak rate for enteric anastomoses. Alternatively, the decontamination disrupts the normal flora of the gastrointestinal tract and may affect normal physiology, including immunologic function. This study reports complication rates of an intestine transplant program that has never used bowel decontamination...

BACKGROUND: Disturbance of intestinal wound closure leads to insufficient anastomotic healing and is associated with considerable morbidity following colorectal resections. Matrix metalloproteinases (MMPs) play a crucial role in regulation of wound closure. Here fluorescence endoscopy was evaluated for assessment of MMP-2/-9 expression during failed intestinal anastomotic healing. METHODS: Distal colonic anastomoses were performed as a model for disturbed healing in 36 Balb/c mice...

BACKGROUND: Whereas the adult literature has demonstrated the acceptable safety profile of stapled anastomoses when compared to the hand-sewn alternative, the choice of intestinal anastomosis using sutures or staples remains inadequately investigated in children. The purpose of this study is to compare the anastomotic outcomes of both techniques in children under 5years of age. METHODS: A retrospective analysis of patients undergoing intestinal anastomosis at a single tertiary centre (2012-2016) was undertaken...

Cancer patients treated with radiotherapy (RT) could develop severe late side effects that affect their quality of life. Long-term bowel complications after RT are mainly characterized by a transmural fibrosis that could lead to intestinal obstruction. Today, surgical resection is the only effective treatment. However, preoperative RT increases the risk of anastomotic leakage. In this study, we attempted to use mesenchymal stromal cells from adipose tissue (Ad-MSCs) to improve colonic anastomosis after high-dose irradiation...

HISTORY AND FINDINGS UPON ADMISSION:  A 50-year-old man presented at the emergency unit with abdominal pain in the right lower quadrant and dysuria. He described an increase in pain during micturition. EXAMINATIONS:  After multiple examinations (CT-scan, MR-scan, ileocolonoscopy) were performed to no avail, a toothpick was detected in the terminal ileum during an ultrasound scan of the small intestine. Prompted elevation of intra-abdominal pressure led to migration of the radiolucent sharp foreign body into the wall of the urinary bladder, inducing pain...

Anastomotic leak (AL) is a serious complication of intestinal surgery with various predisposing factors. This study aims to assess several risk factors associated with AL after small intestinal and colonic anastomoses through a multivariate analysis. Two hundred twenty-four patients (126 males) with intestinal anastomosis of a median age of 44 years were reviewed. Independent factors associated with AL were male gender (OR = 2.59, P  = 0.02), chronic liver disease (CLD) (OR = 8.03, P  < 0.0001), more than one associated comorbidity (OR = 5...
