When performing laparoscopic gastrectomy, suturing the intestinal anastomosis presents one of the greatest challenges. The V-Loc unidirectional barbed suture has been introduced to eliminate the need to tie knots during closure. This device offers a fast, secure, and effective alternative to conventional suture repair during laparoscopic surgery. However, there have been reported cases of surgi...

Stricture formation is recognized as one of the complications of chronic radiation enteritis. Here, we present a case of a 73-year-old woman who presented with small bowel obstruction 16 years after pelvic irradiation for uterine cancer. Computed tomographic (CT) scan of the abdomen demonstrated a 1-cm foreign body in the terminal ileum. Laparotomy revealed a stone of ume (Japanese apricot) stu...

BACKGROUND The small bowel (SB) represents the most important dose-limiting structure in pelvic radiotherapy (RT). However, we observed that the majority of rectal cancer patients who received preoperative pelvic intensity modulated RT (IMRT) developed acute tenesmus without watery diarrhea. The objective of this study is to determine if the RT dose to SB affects the acute lower gastrointestina...

Epidemiological studies suggest that nonsteroidal anti-inflammatory agents decrease the risk of colorectal cancer. This is believed to be mediated, at least in part, by inhibition of cyclooxygenase (COX) activity. There are two COX isoenzymes, namely the constitutively expressed COX-1 and the inducible COX-2. COX-2 is overexpressed in adenomas and colorectal cancers, and COX-2-specific inhibito...

We report herein the case of a patient successfully treated by transhepatic portal venous stent placement for malignant portal vein obstruction with associated gastric and small bowel varices and repeated gastrointestinal bleeding. CT angiography and portography showed severe portal vein obstruction from recurrent pancreatic cancer 15 months following pancreaticoduodenectomy with tumor encaseme...

Cancers of the small bowel are relatively rare and account for approximately 1-2% of all gastrointestinal neoplasms. The most common histologic subtype - adenocarcinoma - constitutes 40% of all cases. These cancers generally present with vague abdominal discomfort and are often diagnosed at a late stage and carry a poor prognosis. The treatment of choice of early-stage small bowel adenocarcinom...
