Endometriosis with an acute colon obstruction: a case report

Endometriosis as an Uncommon Cause of Intestinal Obstruction-A Comprehensive Literature Review

The prevalence of intestinal endometriosis has been estimated to be between 3% and 37% of all endometriosis cases. Cases of intestinal occlusion due to endometriosis foci on the small bowel and on the large bowel are even rarer, with a reported prevalence of 0.1-0.7%. The aim of this literature review was to summarize the available published evidence on the diagnosis, characteristics, and management of intestinal occlusion due to endometriosis. The search on PubMed retrieved 295 records, of which 158 were rejected following a review of the title and abstract. After reviewing the full text, 97 studies met the Population, Intervention, Comparator, Outcomes, and Study (PICOS) criteria and were included in the analysis. The total number of patients with bowel occlusion due to endometriosis included in the studies was 107. The occlusive endometrial foci were localized on the ileum in 38.3% of the cases, on the rectosigmoid in 34.5% of the cases, at the ileocecal junction and the appendix in 14.9% of the cases, and at the rectum in 10.2% of the cases. Only one case reported large bowel obstruction by endometriosis of the hepatic flexure of the colon extending to the transverse colon (0.9%), and in one case the obstruction was caused by an omental giant endometrioid cyst compressing the intestines. We identified six cases of postmenopausal females with acute bowel obstruction due to endometriosis. Malignant degeneration of endometriosis was also identified as a cause of intestinal occlusion. The mechanisms of obstruction include the presence of a mass in the lumen of the intestine or in the wall of the intestine, extrinsic compression, adhesions, or intussusception.

Acute abdominal pain in women of reproductive age: keys to suggest a complication of endometriosis

Although endometriosis is a common gynecological condition in women of reproductive age, a complication of endometriosis is rarely considered as the differential diagnosis of acute abdominal pain in that context. However, acute events in women with endometriosis can represent life-threatening conditions, which require emergent treatment and often surgical management. Mass effect of endometriotic implants can give rise to obstructive complications, specifically occurring in the bowel or in the urinary tract, while inflammatory mediators released by ectopic endometrial tissue can lead to inflammation of the surrounding tissues or to superinfection of the endometriotic implants. Magnetic resonance imaging is the best imaging modality to reach the diagnosis of endometriosis, but an accurate diagnosis is possible on computed tomography, especially in the presence of stellar, mildly enhanced, infiltrative lesions in suggestive areas. The aim of this pictorial review is to provide an image-based overview of key findings for the diagnosis of acute abdominal complications of endometriosis.

Endometriosis Causing Large Bowel Obstruction: A Case Report

Endometriosis is defined as the presence of endometrial glands and stroma in ectopic locations, with extrapelvic sites being less commonly affected. Only a few cases of colonic endometriosis causing acute bowel obstruction have been reported in the literature, in which resection and primary anastomosis were the treatments performed. We present the case of a 40-year-old female who presented with signs and symptoms of acute large bowel obstruction thought to be due to malignancy; however, further evaluation confirmed the diagnosis of rectosigmoid endometriosis. The management plan was an immediate laparotomy with rectosigmoid resection and primary anastomosis.

One-stage, radical laparoscopic endometriosis excision involving three different organ systems: A case report from tertiary referral center

Introduction:

We present a case of an extensive endometriosis involving left paracolpium and left parametrium, rectovaginal septum, urinary bladder, left interiliac region between artery and vein, left ureter and rectum, presenting as dysmenorrhoea, alternating bouts of diarrhea and constipation and hydronephrosis.

Methods:

Laparoscopic surgery made by a multidisciplinary team consist of gynecologic, abdominal surgeon and urologist.

Results:

Successfully managed deep infiltrated endometriosis.

Conclusion:

The aim of this report is to demonstrate benefit of one-stage, minimally invasive radical surgical procedure performed in a tertiary referral center. To the best of our knowledge, this report presents an extremely complex case because we successfully managed deep infiltrating endometriosis in three different organ systems at the same time, using minimally invasive nerve-sparing technique. A case with the same constellation has not been published yet since reported cases of extrapelvic endometriosis chiefly address one organ system involvement.

Acute abdominal pain in non-pregnant endometriotic patients: not just dysmenorrhoea. A systematic review

Endometriosis, defined as the presence of functional endometrial tissue outside the uterine cavity, presents mainly with pelvic pain and infertility. Acute abdominal pain in non-pregnant patients with endometriosis might be minimised as a typical feature of the disease, while endometriosis is rarely considered in the differential diagnosis of acute abdominal pain. Our objective was to conduct a systematic review of the current literature of cases of acute abdomen/acute abdominal pain in non-pregnant endometriotic patients. We performed a PubMed/MEDLINE search of studies published from January 1990 to December 2018, selecting English language reports and series of non-pregnant patients with acute abdomen and histological confirmation of endometriosis. The studies were revised by two independent authors. Data were abstracted and compiled for analysis. Fifty articles reporting 62 patients were identified. The complications were classified according to anatomical sites in bowel, urinary tract, and genital organs emergencies. Rarely was the first diagnostic hypothesis endometriosis, misdiagnosis was frequent. The time frame from symptoms onset to management was often long. This is the first systematic review evaluating acute abdomen/acute abdominal pain in non-pregnant endometriotic patients. These conditions are rare but possibly life-threating and require prompt diagnosis and emergent medical or surgical treatment.

Endometriosis Mimicking a Cecum Mass with Complete Bowel Obstruction: An Infrequent Cause of Acute Abdomen

Endometriosis is a common entity among fertile women which unfortunately manifests through variable symptomatology. Intestinal involvement in endometriosis is quite common and can simulate several diseases such as Crohn's disease, appendicitis, tubo-ovarian abscess, or malignant tumors. Intestinal obstruction due to endometriosis is rare, and preoperative diagnosis is difficult because the signs and symptoms are nonspecific and can be easily confused. In the case of patients without a history of endometriosis, diagnosis is further complicated. We present a case of a 41-year-old female patient. She presented to the emergency room with complete bowel obstruction and a mass in the cecum. Surgery was decided, and the patient underwent full recovery. Endometriosis was the final diagnosis for the observed condition.

Intestinal obstruction caused by endometriosis: Endoscopic stenting and expedited laparoscopic resection avoiding stoma. A case report and review of the literature

INTRODUCTION

Endometriosis is the growth of endometrium outside the uterine cavity. In 5-15% of cases the disease can affect the colon and small bowel, causing complete obstruction and requiring resection in about 1% of cases.

CASE SUMMARY

We describe a case of sigmoid obstruction due to endometriosis in a 38 years old woman with personal history of endometriosis. She was admitted for abdominal pain and constipation. The patient was treated with endoscopic stenting and subsequent laparoscopic sigmoidectomy.

DISCUSSION

Bowel obstruction caused by endometriosis is a rare event. Its diagnosis can thus be a clinical and radiological challenge but it may be suspected in all young woman with colonic obstruction. At present, the management of endometriosis is an integrate approach of both medical and surgical therapy. In case of irreversible colonic obstruction surgery is mandatory. The treatment of choice is usually an emergency procedure (either Hartmann procedure or resection and anastomosis with stoma placement). This approach entails all the risks related to emergency procedures and can have important psychological and biological drawbacks.

CONCLUSION

Endoscopic prosthesis placement as bridge to surgery is a feasible therapeutic strategy in colonic obstruction due to endometriosis. It brings about all the advantages of an expedited one step laparoscopic surgical procedure. Laparoscopic elective resection has a lower rate of stoma placement and has a postoperative pregnancy rate grater than open surgery.

Laparoscopic Treatment of a Retroduodenopancreatic Endometriotic Cyst Observed Postpartum

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.
