The outcomes of laparoscopic resection of bowel endometriosis

Endometriosis in the Cecum: A Rare Clinical Entity

Cecal endometriosis is uncommon and may mimic other tumors of the colon, making it difficult to safely diagnose preoperatively. We report a case of a 50- year-old female who was found to have a cecal lesion during an endoscopic examination, which was performed for the investigation of anemia. It was also confirmed by conducting a computed tomography (CT) scan. Due to the high possibility of this mass identification as a neoplasm, the patient underwent a laparoscopic right hemicolectomy with an extracorporeal side-to-side isoperistaltic anastomosis. However, the postoperative histological diagnosis of the mass was cecal endometriosis, as the histopathology report noted endometrial tissues in the submucosa and muscolaris propria of the ileocecal region. Endometriosis of the cecum is a rare manifestation and can often be misdiagnosed as a malignant tumor. Further research is required, concerning preoperative characteristics of bowel masses in women, in order to provide optimal operative treatment and avoid unnecessary invasive procedures.

Preservation of the inferior mesenteric artery in laparoscopic nerve-sparing colorectal surgery for endometriosis

Laparoscopic rectosigmoid resection for endometriosis is usually performed with the section of the inferior mesenteric artery (IMA) distal to the left colic artery (low-tie ligation). This study was to determine outcomes in IMA-sparing surgery in endometriosis cases. A single-center retrospective study based on the analysis of clinical notes of women who underwent laparoscopic rectosigmoid segmental resection and IMA-sparing surgery for deep infiltrating endometriosis with bowel involvement between March the 1st, 2018 and February the 29th, 2020 in a referral hospital. During the study period, 1497 patients had major gynecological surgery in our referral center, of whom 253 (17%) for endometriosis. Of the 100 patients (39%) who had bowel endometriosis, 56 underwent laparoscopic nerve-sparing rectosigmoid segmental resection and IMA-sparing surgery was performed in 53 cases (95%). Short-term complications occurred in 4 cases (7%) without any case of anastomotic leak. Preservation of the IMA in colorectal surgery for endometriosis is feasible, safe and enables a tension-free anastomosis without an increase of postoperative complication rates.

Laparoscopic treatment of deep infiltrating endometriosis: results of the combined laparoscopic gynecologic and colorectal surgery

BACKGROUND

The short-term results of a retrospective consecutive series of multidisciplinary laparoscopic approach to deep infiltrating endometriosis with intestinal involvement requiring segmental bowel resection procedures are presented.

METHODS

Patients with radiologically or intraoperative-confirmed endometriosis, who underwent a combined laparoscopic segmental bowel resection by a team of gynecologists and colorectal surgeons, were retrospectively reviewed. The postoperative data were collected in a specific database and analyzed for short-term (30 days) postoperative outcomes with the comparison between two specimen's extraction methods.

RESULTS

Forty-one patients (median age of 36 years, range 25-44) have been operated by a combined team of gynecologist and colorectal surgeons. The median operative time was 247.5 min (range 155-375), and median estimated blood loss was 300 ml (range 100-1300). In 20 patients, the surgical specimens were extracted transvaginally, while in 21 cases, a sovrapubic transverse Pfannenstiel minilaparotomy was used. No intraoperative complications or conversion to laparotomy were reported. An acceptable cumulative rate of postoperative morbidity was observed (6/41, 15 %), without any postoperative deaths. Comparing the two subgroups of patients with different modalities of specimen retrieval, postoperative pain (assessed by visual analog scale) was significantly reduced in the transvaginal extraction group (median: 1 and range: 0-2 vs median: 3, 5 and range: 1-6; p = 0.002), without any statistically significant differences in terms of complications.

CONCLUSION

Laparoscopic bowel segmental resection combined with gynecologic surgery for deep infiltrating endometriosis with intestinal involvement is a valid treatment option with a low rate of postoperative complications. Transvaginal specimen extraction allows the same results of minilaparotomic incision, minimizing surgical trauma and warranting a clear benefit in terms of reduction of postoperative pain.

Diagnosis, management, and long-term outcomes of rectovaginal endometriosis

Rectovaginal endometriosis is the most severe form of endometriosis. Clinically, it presents with a number of symptoms including chronic pelvic pain, dysmenorrhea, deep dyspareunia, dyschezia, and rectal bleeding. The gold standard for diagnosis is laparoscopy with histological confirmation; however, there are a number of options for presurgical diagnosis, including clinical examination, transvaginal/transrectal ultrasound, magnetic resonance imagining, colonoscopy, and computed tomography colonography. Treatment can be medical or surgical. Medical therapies include birth control pills, oral progestins, gonadotropin-releasing hormone agonists, danazol, and injectable progestins. Analgesics are often used as well. Surgery improves up to 70% of symptoms. Surgery is either ablative or excisional, and is conducted via transvaginal, laparoscopic, laparotomy, or combined approaches. Common surgical techniques involve shaving of the superficial rectal lesion, laparoscopic anterior discoid resection, and low anterior bowel resection and reanastomosis. Outcomes are generally favorable, but postoperative complications may include intra-abdominal bleeding, anastomotic leaks, rectovaginal fistulas, strictures, chronic constipation, and the need for reoperation. Recurrence of rectal endometriosis is a possibility as well. Other outcomes are improved pain-related symptoms and fertility. Long-term outcomes vary according to the management strategy used. This review will provide the most recent approaches and techniques for the diagnosis and treatment of rectovaginal endometriosis.

Bowel Endometriosis with Hemoperitoneum Complicating Pregnancy

Case Report

We report a case of bowel endometriosis complicated by spontaneous hemoperitoneum and miscarriage in a 33-year-old primigravida at the 24th week of gestation. An emergency laparotomy showed spontaneous rupture of the left uterine artery and bowel wall endometrioma. Artery suture, bowel resection and cesarean section on demised fetus were performed.

Conclusions

Although pregnancy may have beneficial effects on endometriosis, rare but significant endometriosis-associated pregnancy complications may also occur.
