Colonoscopy is routinely used for the diagnosis and treatment of colorectal diseases. Bowel perforation is a rare but severe complication that significantly increases the morbidity and mortality. Tension pneumothorax is an uncommon complication of colonic perforation. We present a case of the successful treatment of a patient with tension pneumothorax, following colonoscopy, by using tube thoracostomy and Hartman-type resection of the rectosigmoid junction and proximal sigmoid. Surgeons, anesthesiologists, and endoscopists should consider the possibility of pneumothorax as a rare complication of colonoscopy. Early detection and urgent treatment is the key to successful management.

Pancreatic parenchyma-preserving procedures performed for benign and low-grade malignant tumors of the neck or body of this organ significantly reduce the incidence of postoperative exocrine and endocrine insufficiency compared to distal pancreatectomy. Tumor enucleation spares pancreatic parenchyma, but it can have positive surgical margins, and postoperative leakage after it is significant. We present our initial successful experience of laparoscopic central pancreatectomy. A patient was operated on for cystadenoma of the pancreatic neck. The organ was transected proximally with a linear stapler but distally with ultrasonic shares, and a caudal stump was used for the creation of the pancreaticogastrostomy. The postoperative period was uneventful. The four-month follow-up did not reveal any exocrine or endocrine insufficiency.

We present a case of the multiple venous intestinal infarction in patient with two inherited thrombophilias: Leiden factor V (LFV) and factor VIII elevation. The patient had a critical hypocoagulation caused by vitamin K antagonist (VKA) overdose. At laparotomy, several intestinal segments were necrotic and ischemic. Coagulopathy was corrected by the transfusion of the fresh frozen plasma. Because of the 4th duodenal segment infarction distal segmental duodenectomy with side-to-side duodenojejunostomy was done, which is a rarely performed procedure. On postoperative day 6 deep vein thrombosis developed, despite nadroparin profillaxes, early mobilisation and compressive stockings. Our case demonstrated that in patients with congenital thrombophilia, development of the mesenteric venous thrombosis is possible even with VKA induced severe hypocoagulation. Venous infarction of the small bowel can be associated with the hemoperitoneum and gastrointestinal bleeding. After resection of the fourth duodenal segment, side-to-side duodenojejunostomy is a feasible method of reconstruction.
