Two kinds of intestinal sutures performed with the use of a precision technique were investigated on models of acute intestinal obstruction. One-row (serous-muscular-submucosal) and two-row (serous-musculo-submucosal and submucosal-mucosal) sutures provide an exact layer-after-layer connection of the intestinal wall layers and a sufficient mechanical firmness of the anastomosis with little traumatization. The dynamics of microcirculation changes in the anastomosis zone was followed with the help of contact intraoperative biomicroscopy. Symptoms of the traumatic inflammation were cupped off within 5 days and changed by reparative processes.

The duodenal diverticulum is a relatively frequent entity whose diagnosis has been increased over time with the development of new diagnostic and exploratory techniques. Periampullary diverticula (PAD) were classified as type 1, 2, or 3 according to the position of the major papilla from the endoscopic view: type 1, the major papilla was located inside of the diverticula; type 2, the major papilla was located at the edge of the diverticula; type 3, the major papilla was located outside of the diverticula. Complications of duodenal diverticula include ulceration, bleeding, perforation and inflammation with intestinal obstruction.

We present a case of a woman in her 70s who arrived in the emergency department with signs of small-bowel obstruction. CT scanning revealed acute cholecystitis with a cholecystoduodenal fistula, pneumobilia and small-bowel obstruction possibly secondary to gallstone ileus although no radio-opaque gallstones were seen. The patient underwent an emergency operation and intra-operative findings revealed mechanical small-bowel obstruction of the proximal jejunum where a 4×2 x 3 cm gallstone was impacted.

We report here a case of acute intestinal obstruction caused by an unusual rectal stenosis, for which he underwent a diversion stoma. On extensive evaluation for the etiology of the rectal stenosis, he was diagnosed with diffuse gastric cancer with Schnitzler's metastasis to the rectal submucosa.
