Gardner's syndrome(GS) is a rare syndrome with autosomal dominant inheritance, which is characterized by multiple intestinal polyps, dental anomalies, desmoid tumors, and soft tissue tumors. All gastrointestinal symptoms seen in GS are associated with the underlying familial adenomatosis polyposis and abdominal desmoid tumors, with the most common symptoms being anemia, lower gastrointestinal bleeding, abdominal pain, diarrhea, obstruction, and mucous defecation. To our best knowledge, no case of GS that has presented with gastrointestinal perforation and bleeding has ever been reported in the English language medical literature. A 37-year-old male who had been diagnosed with GS five years earlier was referred to our clinic for lower gastrointestinal bleeding. Despite the absence of a bleeding focus on conventional angiography, the patient was operated on with laparotomy, due to the persistence of both signs and symptoms of mild peritonitis. On the laparotomy, the patient was noted to have areas of perforation in the duodenum, splenic flexura, and midrectum. The third and fourth part of the duodenum, the proximal 15 cm segment of the jejunum, a 10 cm segment of the terminal ileum, the whole colon, and the upper and middle rectum were resected, and duodenojejunal side-to-side anastomosis and terminal ileostomy were performed. The histopathological analysis of the large mass measuring 30 cm × 20 cm was reported as a desmoid tumor. The pathological examination of the tumor foci detected in the colonic specimen revealed poorly differentiated adenosquamous carcinoma.

With the developments in medical technology and increased surgical experience, advanced laparoscopic surgical procedures are performed successfully. Laparoscopic abdominal surgery is one of the best examples of advanced laparoscopic surgery (LS). Today, laparoscopic abdominal surgery in general surgery clinics is the basis of all abdominal surgical interventions. Laparoscopic abdominal surgery is associated with systemic and splanchnic hemodynamic alterations. Inadequate splanchnic perfusion in critically ill patients is associated with increased morbidity and mortality. The underlying pathophysiological mechanisms are still not well understood. With experience and with an increase in the number and diversity of the resulting data, the pathophysiology of laparoscopic abdominal surgery is now better understood. The normal physiology and pathophysiology of local and systemic effects of laparoscopic abdominal surgery is extremely important for safe and effective LS. Future research projects should focus on the interplay between the physiological regulatory mechanisms in the splanchnic circulation (SC), organs, and diseases. In this review, we discuss the effects of laparoscopic abdominal surgery on the SC.

BACKGROUND Most patients with hydatid cysts are asymptomatic, and they are diagnosed incidentally during radiological evaluations performed for other ***, some patients develop symptoms and complications due to cyst size,location, and the relationship between the cyst and adjacent structures. The most serious complications that can occur are rupture of the cysts into the biliary tract,vascular structures, hollow viscus, and peritoneal cavity. We aimed to describe the management of four cases of intraperitoneal rupture of hydatid *** SUMMARIES Four patients aged between 27 and 44 years(two men and two women) were admitted to our clinic with sudden abdominal pain(n = 4), hypotension(n = 3),and anaphylaxis(n = 2). Three of the perforated cysts were located in the liver,and one was located in the spleen. Two patients developed cyst rupture after minor trauma, and the other two developed spontaneous rupture. Enzymelinked immunosorbent assay IgG results were positive for two patients and negative for the other two. All patients received albendazole treatment after surgical intervention(range: 2-6 mo). Two patients developed hepatic abscesses requiring drainage; one of these patients also developed hydatid cyst recurrence during postoperative follow-up(range: 25-80 mo).CONCLUSION Intraperitoneal rupture is a life-threatening complication of hydatid cysts. It is important to manage patients with surgical intervention as soon as possible with aggressive medical treatment for anaphylactic reactions.
