Review
Radical gastrectomy with extended lymph node dissection and prophylactic resection of the omentum, peritoneum over the posterior lesser sac, pancreas and/or spleen was advocated at the beginning of the 1960s in Japan. In time, prophylactic routine resections of the pancreas and/or spleen were abandoned because of the high incidence of postoperative complications. However, omentectomy and bursectomy continued to be standard parts of traditional radical gastrectomy. The bursa omentalis was thought to be a natural barrier against invasion of cancer cells into the posterior part of the stomach. The theoretical rationale for bursectomy was to reduce the risk of peritoneal recurrences by eliminating the peritoneum over the lesser sac, which might include free cancer cells or micrometastases. Over time, the indication for bursectomy was gradually reduced to only patients with posterior gastric wall tumors penetrating the serosa. Despite its theoretical advantages, its benefit for recurrence or survival has not been proven yet. The possible reasons for this inconsistency are discussed in this review. In conclusion, the value of bursectomy in the treatment of gastric cancer is still under debate and large-scale randomized studies are necessary. Until clear evidence of patient benefit is obtained, its routine use cannot be recommended.

Abdominal cocoon syndrome is rare cause of intestinal obstruction characterized by small bowel encapsulation by a fibro-collagenous membrane or "cocoon".A 30 yearman presented in emergency department with abdominal pain. Preoperatively contrast enhanced computed tomography of abdomen revealed encapsulated cluster of mildly dilated and edematous small bowel loops with multiple air fluid levels with thin membrane and crowding of mesenteric vessels in left upper quadrant.Intra-operatively, the entire small bowel was found to be encapsulated in a dense fibrous sac. The peritoneal sac was excised, followed by lysis of the inter-loop adhesionswith smooth postoperative recovery.High index of suspicion is required in patient presenting with features of recurrent acute or chronic small bowel obstruction for diagnosis of abdominal cocoon syndrome. Contrast enhanced Computed Tomography of abdomen is a useful radiological to aid in preoperative diagnosis of syndrome. Keywords: Abdomen; abdominal cocoon; CECT; encapsulated cluster.

An ectopic pregnancy (EP) accounts for 1-2% of all pregnancies, of which 90% implant in the fallopian tube. An abdominal ectopic pregnancy (AEP) is defined as an ectopic pregnancy occurring when the gestational sac is implanted in the peritoneal cavity outside the uterine cavity or the fallopian tube. Implantation sites may include the omentum, peritoneum of the pelvic and abdominal cavity, the uterine surface and abdominal organs such as the spleen, intestine, liver and blood vessels. Primary abdominal pregnancy results from fertilisation of the ovum in the abdominal cavity and secondary occurs from an aborted or ruptured tubal pregnancy. It represents a very rare form of an EP, occurring in <1% of cases. At early gestations, it can be challenging to render the diagnosis, and it can be misdiagnosed as a tubal ectopic pregnancy. An AEP diagnosed >20 weeks' gestation, caused by the implantation of an abnormal placenta, is an important cause of maternal-fetal mortality due to the high risk of a major obstetric haemorrhage and coagulopathy following partial or total placental separation. Management options include surgical therapy (laparoscopy±laparotomy), medical therapy with intramuscular or intralesional methotrexate and/or intracardiac potassium chloride or a combination of medical and surgical management. The authors present the case of a multiparous woman in her early 30s presenting with heavy vaginal bleeding and abdominal pain at 8 weeks' gestation. Her beta-human chorionic gonadotropin (bHCG) was 5760 IU/L (range: 0-5), consistent with a viable pregnancy. Her transvaginal ultrasound scan suggested an ectopic pregnancy. Laparoscopy confirmed an AEP involving the pelvic lateral sidewall. Her postoperative 48-hour bHCG was 374 IU/L. Due to the rarity of this presentation, a high index of clinical suspicion correlated with the woman's symptoms; bHCG and ultrasound scan is required to establish the diagnosis to prevent morbidity and mortality.

Review
Introduction: Not only atraumatic surgical technique, precise bleeding control, removal foreign materials from the abdomen, but also avoiding desiccation or mechanical damage of peritoneal surface at abdominal surgery mean today evidence based expectation. Peritoneum with its extensive surface and special histological structure represents an important factor in normal physiological processes, furthermore as “Guard of abdomen” it has an important role to localise inflammatory reactions, useful as dialysing surface and provides also possibility for hyperthermic abdominal chemotherapy in tumour treatment. Largest part of peritoneal sac covers small intestine and colon. To prevent postoperative complications it is necessary to avoid desiccation of intestinal tract at laparoscopic and at open procedures as well – consequently “rehyration” is a routine recommendation today. Desiccation of intestinal tract results postoperative adhesions, furthermore damage of serosa will increase permeability of intestine wall and can result perforation. All the surgical recommendations suggest keeping intestine moist, whereas there are only a few real studies in surgical literature to support or to deny this theory. Our study reviews the pathophysiological and surgical respects of this situation and summarizes the results of latest researches of combined functions of peritoneum.

Review
Endometriosis affects approximately 10% of reproductive age women and represents a significant cause of pelvic pain and infertility. Unfortunately, the diagnosis of endometriosis is often delayed by years. Endometriosis may manifest as cystic lesions in the ovaries known as endometriomas. Superficial endometriosis is typically detected by laparoscopy along the pelvic peritoneum as these lesions tend to be difficult to detect by imaging. Deep infiltrative endometriosis may be detected by ultrasound, CT or MRI in classic locations within the pelvis, such as the posterior cul-de-sac and uterosacral ligaments. Endometriosis may also involve the thorax, gastrointestinal and urinary tracts, and locations such as the abdominal wall and abdominal organs. We present MRI and CT case examples, together with corresponding laparoscopic and histopathology images to enhance radiologists' understanding of this disease.

Although several studies have reported that the peritoneum does not contribute to the formation of a fascia between the urogenital organs and rectum, Denonvilliers' fascia (DF), a fascia between the mesorectum and prostate (or vagina) in adults, is believed to be a remnant of the peritoneum. Remnants of the peritoneum, however, were reportedly difficult to detect in other fusion fasciae of the abdominopelvic region in mid-term fetuses. To examine morphological changes of the pelvic cul-de-sac of the peritoneum, we examined 18 male and 6 female embryos and fetuses. A typical cul-de-sac was observed only at 7 weeks, whereas, at later stages, the peritoneal cavity did not extend inferiorly to the level of the prostatic colliculus or the corresponding structure in females. The cul-de-sac had completely disappeared in front of the rectum at 8 weeks and homogeneous and loose mesenchymal tissue was present in front of the rectum at the level of the colliculus at 12-16 weeks. We found no evidence that linearly arranged mesenchymal cells developed into a definite fascia. Therefore, the development of the DF in later stages of fetal development may result from the mechanical stress on the increased volumes of the mesorectum, seminal vesicle, prostate and vagina and/or enlarged rectum. Therefore, we considered the DF as a tension-induced structure rather than a fusion fascia. Fasciae around the viscera seemed to be classified into (1) a fusion fascia, (2) a migration fascia and (3) a tension-induced fascia although the second and third types are likely to be overlapped.

Review
The pouch of Douglas may become occupied by a variety of mass-like lesions, which may be challenging to providers who treat women. These lesions may initially be thought to arise from the uterus or adnexa. We conducted a literature review using a Medline search of the terms "Douglas' pouch," "pouch of Douglas," "cul-de-sac," and "rectouterine pouch." A review of the scope of pouch of Douglas lesions is presented to assist in developing a differential diagnosis if a patient with such a lesion is encountered.

A transomental hernia through the greater or lesser omentum is rare, accounting for approximately 4% of internal hernias. Transomental hernias are generally reported in patients aged over fifty. In such instances, acquired transomental hernias are usual, are commonly iatrogenic, and result from surgical interventions or from trauma or peritoneal inflammation. In rare cases, such as the one described in this study, internal hernias through the greater or lesser omentum occur spontaneously as the result of senile atrophy without history of surgery, trauma, or inflammation. A transomental hernia has a high postoperative mortality rate of 30%, and emergency diagnosis and treatment are critical. We report a case of a spontaneous transomental hernia of the small intestine causing intestinal obstruction. An internal hernia with strangulation of the small bowel in the lesser sac was suspected from the image study. After an emergency laparotomy, a transomental hernia was diagnosed.
