Endometriosis occurs in 5%-10% of fertile women, usually in the pelvic region, such as the ovaries, uterine ligaments, pelvic peritoneum, and rectovaginal septum. A mesenteric endometriotic cyst is an exceptional observation and difficult to diagnose preoperatively. We report a case of a large mesenteric endometriotic cyst treated by laparoscopy. A 21-year-old Caucasian woman was admitted as an emergency to our Academic Hospital on the 30th day postpartum for abdominal pain and a palpable epigastric mass. A CT scan revealed a mass measuring 7.5 × 5.5 cm showing a fluid content, located below the pancreas. A preoperative diagnosis of mesenteric cyst was made and confirmed by MRI. A dissection of the mass from the inferior vena cava, pancreas, and duodenum was achieved by a laparoscopic approach. During the blunt dissection, avoiding any spillage, the cyst was aspirated to preserve a safe cleavage plane with the lower third of the duodenum showing tenacious adhesions to the mass. Histology revealed an endometriotic cyst of the mesenterium. To our knowledge, this is the first case reported in the literature of laparoscopic treatment of a retroduodenopancreatic endometriotic cyst observed postpartum. In dedicated centers, laparoscopic management could be the gold standard.

Background and Objectives:Laparoscopic transperitoneal left adrenalectomy (LTLA) has become the standard treatment for adrenal masses <6 cm. LTLA involves the dissection of splenic suspensory ligaments, which replicates their congenital absence or weakening, present in cases of wandering spleen (WS). WS is a rare condition in which the spleen migrates from the left upper quadrant to a more caudal location in the abdomen. A unique case of WS after LTLA was described by Corcione et al. In this prospective study, we investigated the possibility of WS as a consequence of LTLA.Methods:Twenty-four patients, 8 men and 16 women, who underwent LTLA with the dissection of splenoparietal and splenorenal ligaments were selected.Results:Clinical and ultrasonographic follow-up showed no evidence of postoperative WS.Conclusions:In the literature, WS is not commonly reported as a postoperative complication of LTLA. In effect, especially in the case of small adrenal masses, the spleen's repositioning in its seat is autonomous. However, the alarming possibility of WS should not be ignored, especially in the case of extensive dissection of the left colic flexure. It would be useful for other authors to signal this complication, so that different approaches and consequent results may be compared.

Background: Since 1990’s the use of self-expanding metal stent has been known. Initially, this kind of technique has been debated in literature. Actually, is a widely used technique for treatment of bowel neoplastic obstruction. This procedure is important to restore bowel canalization but is feasible performed by expert endoscopists and a dedicated anesthesiologist team. More difficult seems to be the treatment of strictures longer than 9 cm of large bowel or synchronous very close stenosis of rectal-sigmoid junction and rectum. This technical note demonstrated how SEMS positioning can be performed for treatment of long and extreme large bowel obstruction. Methods: In this case series we have treated all patients admitted in our department with diagnosis of extreme bowel neoplastic obstruction, with “stent in stent” technique, in deep sedation. Results: From January to August 2019 we admitted in our Surgical and Endoscopic Unit two patients, a 90- year-old for bowel obstruction by synchronous colorectal cancer and a 80-year-old female for 15 cm large bowel neoplastic obstruction. Patients were submitted to “Stent-in-Stent” technique. No complications and perforation were observed with restore of bowel canalization after few hours from SEMS positioning. Both patients had no signs of bowel obstruction at abdomen X-Ray control, after 48 hours. 80-year-old female patient was submitted to left colectomy after 6 days without complications, while 90-year-old was discharge after 3 days. Conclusion: This study demonstrated how is possible to perform endoscopic SEMS positioning to treat longer than 15 cm neoplastic large bowel obstruction and synchronous colorectal cancer with “Stent-inStent” technique. Our technical note describes, point by point, all passages of this procedure and suggests as is possible to treat synchronous sigmoid-rectal neoplastic obstruction using two different kind of metal stent.
