Introduction: The Boston Scientific Swiss LithoClast® Trilogy lithotripter was intended for use in percutaneous nephrolithotomy. We performed, to our knowledge, the first two robotic pyelolithotomies using the Trilogy lithotripter for intracorporeal lithotripsy.

Case description: Two cases are presented involving a 65-year-old female with a complete left staghorn calculus and hydronephrosis secondary to a left ureteropelvic junction (UPJ) obstruction, and a 69-year-old male with a large left staghorn calculus and multiple large left sided simple renal cysts. In both cases, a robotic pyelolithotomy was scheduled for stone removal along with concurrent UPJ repair and cyst decortication respectively. Following pyeloplasty and cyst decortication respectively, and following stone visualization, the 2.4-mm Trilogy probe was inserted into the 12-mm assistant port and under direct visualization the stone was fragmented and removed using Trilogy's built-in mechanisms. Both patients were treated successfully without complications and were found to be stone-free on follow-up.

Conclusion: The Trilogy lithotripter may be an effective tool for stone management when introduced during robotic pyelolithotomy and provides additional optionality when manual extraction poses challenges.

Pelvic floor hernias represent a rare type of hernia and a rare etiology of pelvic symptoms. The rarest type of pelvic floor hernias are sciatic hernias, which present with a variety of symptoms depending on the hernia contents and location. Many different treatment approaches are described in the literature. A 73-year-old female presented to our outpatient minimally invasive surgery (MIS) clinic with one year of colicky left flank pain. She had previously presented to an emergency department, at which time a computed tomography (CT) scan demonstrated left-sided hydronephrosis in the setting of a left-sided ureterosciatic hernia. She was asymptomatic and had no palpable hernia bulge. An operative repair was offered based on her prolonged symptoms. The patient was brought electively to the operating room with minimally invasive and urological surgeons. A left ureteral stent was placed over a guidewire. A robotic repair was performed with a round piece of biosynthetic mesh, secured in place with fibrin glue. Sciatic hernias are an extremely rare etiology of pelvic symptoms and require a high index of suspicion to identify. Obstructive and neuropathic symptoms may be intermittent, so diagnosis is often made using CT imaging. We report a successful treatment with pre-operative ureteral stenting followed by a robotic repair using biologic mesh secured with fibrin glue fixation. We believe this is a durable repair although acknowledge that longer follow-up is needed to establish the longevity of our treatment modality.

Introduction: We report a case of a patient who presented with incarceration of the epiploic appendix in a spigelian hernia, subsequently treated by a robotic-assisted surgical approach.

Case description: This is a case of a 52 year-old male patient who presented with nausea and two-week history of worsening left lower quadrant pain. On examination, the patient had an irreducible left lower quadrant mass. Computed tomography scan showed an epiploic appendagitis in a left Spigelian hernia. The patient underwent a robotic transabdominal preperitoneal hernia repair successfully and was discharged home the same day.

Conclusion: The robotic platform was a safe and effective approach to treating the patient with no postoperative complications.

Epithelial tumors with neuroendocrine and nonendocrine components constitute the rare yet aggressive entity of neoplasms of the gastro-entero-pancreatic tract. These tumors were first named "mixed adeno-neuroendocrine carcinomas" (MANECs) by the World Health Organization in 2010 and in 2017 renamed "mixed neuroendocrine non-neuroendocrine neoplasms" (MiNENs). Combined adenocarcinoma and neuroendocrine carcinoma neoplasms are a rare occurrence within the gastrointestinal tract. In this report, we describe two separate cases of mixed rectal adeno-neuroendocrine carcinomas and their treatment. We describe two cases at one institution of mixed neuroendocrine non-neuroendocrine rectal neoplasms. Given the rarity of diagnosis and inconsistencies in both nomenclature and treatment recommendations in the literature, mixed adeno-neuroendocrine carcinoma epidemiology and prognosis are not yet fully understood. Future prospective trials with a focus in management of MiNENs will offer valuable insight into these rare mixed carcinomas.

Introduction: Internal hernias are the most common cause of small bowel obstruction following laparoscopic Roux-en-Y gastric bypass surgery (LRYGBP) with four distinct types. Herein, we report the clinical course of a patient with two independent hernias at the Petersen's space and a rarer subtype at the jejunojejunal window. A high index of suspicion for less common subtypes of internal hernias and the possibility of multiple, simultaneous internal hernias is critical.

Case description: We describe the case of a 52-year-old female with a history of LRYGBP who presented with abdominal pain and emesis due to an internal hernia at Peterson's defect, requiring subsequent laparoscopic repair. On postoperative day three, the patient presented again with recurrent abdominal pain and emesis. Repeat exploratory laparoscopy found a separate internal hernia involving the jejunojejunal window with the previously repaired Petersen's defect intact.

Discussion: This case illustrates a unique scenario of a patient post-LRYGBP with multiple internal hernias at the Peterson's space and the less common jejunojejunal window, which was missed during the index surgery. Failure to identify simultaneous hernias may result in additional invasive intervention and further morbidity.

Conclusion: Multiple less-common variants of internal hernias may present simultaneously following LRYGBP.

Introduction: To report a case of ovarian torsion following ovarian hyperstimulation with subsequent detorsion and oocyte retrieval.

Case description: The patient was diagnosed with torsion following acute onset abdominal pain following her leuprolide acetate trigger injection. The patient underwent diagnostic laparoscopy which confirmed right ovarian torsion. Following detorsion, the patient underwent oocyte retrieval as planned with 72 total oocytes and 70 mature oocytes retrieved. Thirty-six mature oocytes were cryopreserved; 34 were inseminated with conventional in vitro fertilization, of which 27 (79.4%) were fertilized. Sixteen blastocyst stage embryos were cryopreserved.

Discussion: Ovarian torsion during ovarian hyperstimulation is a rare event, but consideration should be given to detorsion first, followed by oocyte retrieval. We demonstrate that mature oocytes can be retrieved even after temporary vascular compromise to the ovary with subsequent excellent fertilization and blastocyst conversion rates.

Introduction: Cutaneous gluteal vaginal fistula is a rare but significant postoperative complication which may present years after sacrospinous ligament fixation (SSLF) surgery There is limited data on the management of cutaneous vaginal fistula following SSLF.

Case description: This case report describes a 77-year-old who presents twenty years after SSLF with cutaneous gluteal vaginal abscess and fistula. She underwent successful management with CT-guided percutaneous drainage of gluteal abscess and placement of guiding cutaneous vaginal catheter, laparoscopic pelvic wall dissection and evaluation, and transvaginal localization and removal of the infected permanent suture.

Discussion: Multi-disciplinary approach should be considered in the treatment of chronic fistula status post SSLF, including interventional radiology, urogynecology, and minimally invasive gynecologic surgery.

Diaphragmatic hernias are uncommon, and can appear secondary to trauma or as a congenital defect. These hernias can be asymptomatic or have various clinical presentations. One of the clinical scenarios is incarceration of bowel through the diaphragmatic defect. A bowel obstruction from an incarcerated diaphragmatic hernia is a rare occurrence. We present a case of a small bowel obstruction caused by a congenital diaphragmatic hernia that was successfully managed with laparoscopy.

Introduction: Obstructed hemivagina ipsilateral renal agenesis (OHVIRA) is a rare syndrome with limited data on both treatment and postoperative sequelae, specifically of ectopic ureters to the vagina.

Case description: This case study describes a 22-year-old patient with OHVIRA syndrome presenting with pelvic pain and drainage from a chronic vaginal abscess secondary to a remnant distal ectopic ureter after nephrectomy and proximal ureterectomy. Imaging was significant for a right paravaginal abscess. Previously, the patient was treated with conservative therapy and on presentation her evaluation confirmed a right paravaginal abscess. She subsequently underwent a robot-assisted incision and drainage of the paravaginal abscess and excision of the remnant distal ectopic ureter. She did well postoperatively without recurrence.

Discussion: We discuss the successful surgical technique used to identify and excise a paravaginal abscess. We also highlight the unique anatomy of a patient with OHVIRA syndrome. Lastly, we underline the importance of a complete resection of an ectopic ureter to the vagina at the time of nephrectomy, given the potential risk of ascending chronic infection and recurrent abscess formation.

Background: We present two cases of incidentally found heterotopic pancreas during laparoscopic bariatric surgery. Heterotopic pancreas is a rare congenital anomaly where pancreatic tissue is located outside of the pancreas. These lesions may be encountered incidentally during surgery, which raise unexpected management questions.

Case 1: A single pathology confirmed ectopic pancreas lesion encountered in the jejunem during laparoscopic Roux-en Y gastric bypass.

Case 2: Two pathology confirmed heterotopic pancreas lesions encountered in the jejunem during laparoscopic Roux-en Y gastric bypass.

Discussion: Heterotopic pancreas lesions are generally benign and encountered incidentally during intra-abdominal surgery. Surgeons must decide whether to resect the incidentally found mass. When encountered intraoperatively, a heterotopic pancreas lesion found in the small bowel without concerning features should be considered benign and does not warrant resection or biopsy.
