Fertility sparing double discoid excision of rectosigmoid deep endometriosis under robotic-integrated ultrasound guidance.

OBJECTIVE: To present the use of robotic-integrated ultrasound for performing a double discoid excision of multifocal rectosigmoid endometriosis. DESIGN: Video article. STATEMENT OF CONSENT: The patient included in this video gave consent for publication of the video and posting of the video online, including social media, journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus), and other applicable sites. PATIENT: A 26-year-old G0 woman with chronic pelvic pain, dyschezia, and dysmenorrhea refractory to medical management desired future fertility. Imaging was suggestive of deep infiltrating endometriosis involving the rectosigmoid colon. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Double discoid excision of multifocal rectosigmoid endometriosis using robotic-integrated ultrasound. RESULTS: Not applicable. CONCLUSIONS: Performing a complete preoperative evaluation in patients with suspected endometriosis is important for determining the extent of disease and necessity of a multidisciplinary approach. Robotic-integrated ultrasound can provide additional information, including the size and depth of bowel endometriosis lesions, which can play a role in surgical decision making. Performing a double discoid excision of multifocal rectosigmoid endometriosis using robotic-integrated ultrasound is a technique that can avoid the need for a segmental bowel resection.

Laparoscopic shaving of rectosigmoid deep infiltrating endometriosis under laparoscopic ultrasound guidance.

OBJECTIVE: To present laparoscopic shaving of rectosigmoid endometriosis using the novel approach of laparoscopic ultrasound guidance to enhance complete excision. DESIGN: Video article. SETTING: Academic Tertiary Hospital. PATIENT(S): A 41-year-old G3P2012 female with longstanding history of pelvic pain refractory to medical management. Imaging was suggestive of deep infiltrating endometriosis involving the rectosigmoid colon. INTERVENTION(S): Laparoscopy for rectosigmoid endometriosis with the use of intraoperative ultrasound. MAIN OUTCOME MEASURE(S): Laparoscopic excision of rectosigmoid endometriosis under ultrasound guidance. RESULT(S): N/A. CONCLUSION(S): It is important to perform a complete pre-operative evaluation to determine the extent of disease and the necessity of a multidisciplinary approach. Intraoperative laparoscopic ultrasound can provide additional information including size and depth of lesions, which could play a role in surgical decision making. Laparoscopic ultrasound may enhance complete excision of deep endometriosis lesions and decrease the incidence of recurrence.

Obstetric rectal laceration in the absence of an anal sphincter injury.

Rectal laceration in the absence of concurrent anal sphincter injury at the time of parturition is not a frequently reported finding. This rarely encountered injury is also referred to as a buttonhole injury. It is a disruption of the vaginal and rectal tissue with resultant disruption of the anal epithelium in the setting of an intact external anal sphincter. A 30-year-old gravida 1 para 0 at 39 weeks presented for induction of labour due to chronic hypertension. During her labour course, she developed with superimposed preeclampsia with severe features and magnesium sulfate was initiated. She underwent a spontaneous vaginal delivery of an infant weighing 3840 g. Following delivery, stool was visualised in the vagina. A rectal examination revealed a rectovaginal defect separate from the second-degree perineal laceration, which extended proximally to the cervix. The anal sphincter was noted to be intact with good tone. Both defects were repaired, and she had an uncomplicated recovery.

Percutaneous hepatic perfusion with melphalan in uveal melanoma: A safe and effective treatment modality in an orphan disease.

BACKGROUND: Metastatic uveal melanoma (UM) carries a poor prognosis; liver is the most frequent and often solitary site of recurrence. Available systemic treatments have not improved outcomes. Melphalan percutaneous hepatic perfusion (M-PHP) allows selective intrahepatic delivery of high dose cytotoxic chemotherapy. METHODS: Retrospective analysis of outcomes data of UM patients receiving M-PHP at two institutions was performed. Tumor response and toxicity were evaluated using RECIST 1.1 and Common Terminology Criteria for Adverse Events (CTCAE) v4.03, respectively. RESULTS: A total of 51 patients received 134 M-PHP procedures (median of 2 M-PHPs). 25 (49%) achieved a partial (N = 22, 43.1%) or complete hepatic response (N = 3, 5.9%). In 17 (33.3%) additional patients, the disease stabilized for at least 3 months, for a hepatic disease control rate of 82.4%. After median follow-up of 367 days, median overall progression free (PFS) and hepatic progression free survival (hPFS) was 8.1 and 9.1 months, respectively and median overall survival was 15.3 months. There were no treatment related fatalities. Non-hematologic grade 3-4 events were seen in 19 (37.5%) patients and were mainly coagulopathic (N = 8) and cardiovascular (N = 9). CONCLUSIONS: M-PHP results in durable intrahepatic disease control and can form the basis for an integrated multimodality treatment approach in appropriately selected UM patients.

Isolated Limb Infusion: A Single-Center Experience with Over 200 Infusions.

BACKGROUND: Isolated limb infusion (ILI) is a minimally invasive technique for delivering regional chemotherapy to an extremity for patients with locally advanced cutaneous malignancies and sarcoma. METHODS: A single-institution, prospectively collected database was analyzed for intention-to-treat with ILI. RESULTS: From 2007 to 2016, 163 patients underwent 205 procedures (201 were successfully completed), and four malignancies were treated: melanoma (72.1% of all ILIs), sarcoma (23.4%), squamous cell carcinoma (SCC; 2.0%) and Merkel cell carcinoma (MCC; 2.5%). A median grade II regional Wieberdink toxicity score was observed, with 88.1% of patients experiencing grade II or less. Median follow-up was 21.8 months, and overall response rate (ORR) was 59.0% for melanoma, 48.9% for sarcoma, 50.0% for SCC, and 60.0% for MCC. A significant difference (p = 0.04) between upper (76.9%) and lower extremity (55.1%) ORR was observed in patients with melanoma. When comparing responders with nonresponders, patients with melanoma had significantly longer in-field progression-free survival (IPFS; 14.1 vs. 3.2 months, p < 0.001), distant metastatic-free survival (DMFS; not reached vs. 25.8 months, p = 0.006), and overall survival (OS; 56.0 vs. 26.7 months, p = 0.0004). Sarcoma responders had a significantly longer IPFS (13.0 vs. 2.7 months, p < 0.0001), but no significant distant metastatic or OS advantage. Over a median follow-up of 19.3 months, sarcoma patients had an overall limb salvage rate of 68.4%. CONCLUSION: ILI is a well-tolerated procedure for patients with locally advanced melanoma, sarcoma, and other cutaneous malignancies. ILI responders had a significantly longer time to IPFS, while melanoma responders also had a DMFS and OS advantage.
