A Rare Case of Bilateral Retroperitoneal Ovaries: A Case Report and Review of the Literature

Introduction: Retroperitoneal gynecologic tumors and cysts are rare. They are often asymptomatic or present similarly to their intraperitoneal counterpart with vague abdominal discomfort and distention. Our literature review revealed that many retroperitoneal cysts are found intraoperatively due to their benign predominance consistent with their ultrasound findings. The rarity of retroperitoneal gynecologic tumors and cysts creates uncertainty regarding the best practice management for general gynecologists caught off guard by their location when found intraoperatively. Rarer still are retroperitoneal ovaries. There are few cases of retroperitoneal ovary displacement in the literature, most often associated with female neonatal incarcerated inguinal hernia repair surgery. We found one case report involving an intraoperatively found retroperitoneal ovarian cystadenofibroma in a patient with a hernia repair performed in infancy. To our knowledge, there are no bilateral retroperitoneal ovaries described in the literature. Objective: To report a rare case of bilateral retroperitoneal ovaries in an 11 year old female. Methods: Case report. Results: We present an 11-year-old female with a past medical history of Dandy-Walker malformation and hydrocephalus status post ventriculoperitoneal (VP) shunt with six laparoscopic VP shunt revisions who endorsed hirsutism and irregular, heavy, and painful menstrual periods. Her family history is significant for polycystic ovarian syndrome (PCOS), endometriosis, and Lynch syndrome. Physical exam revealed mild abdominal distention and lower abdominal tenderness. She had an elevated estradiol, luteinizing hormone (LH), and total and free testosterone. Normally, an elevated estradiol causes a negative feedback response that results in a low LH. Due to these abnormal results, a pelvic ultrasound was ordered to rule out a potential estrogen secreting ovarian tumor. Ultrasound revealed a large anechoic structure in the left adnexa not definitively separated from the ovary measuring 13.0 x 7.7 x 10.7 cm. Radiologic differential diagnosis included large simple cyst, hemorrhagic cyst, and serous neoplasm. A referral to an adolescent gynecologist was made where the patient presented five months later with 25-pound weight gain, constipation, and a hard belly. Repeat ultrasound was consistent with a left ovarian simple cyst with an increased size measuring 16.78 x 12.58 x 8.66 cm as well as a new finding consistent with a right ovarian simple cyst measuring 4.96 x 4.48 x 3.61 cm. Due to her history of severe abdominal adhesions secondary to multiple laparoscopic VP shunt revisions, likely endometriosis, and large ovarian cyst, she was referred to a gynecologic oncologist where she was consented for robotic assisted bilateral ovarian cystectomy and lysis of adhesions. In the operating room, extensive pelvic adhesions were lysed to reveal bilateral retroperitoneal ovaries. The right cyst was drained of clear fluid, revealing no internal complexity, and was completely excised. Persistent pelvic adhesions and cyst size prolonged the time required to excise the left ovarian cyst wall. Once open, papillary excrescences were seen inside the cyst raising concern for a borderline ovarian tumor. The decision was made to remove the cyst wall in its entirety regardless of increased risk of ovarian function compromise. Restoration of normal anatomy was not attainable, and her bilateral ovaries remained embedded in the side walls and superior to the iliac vessels. Pathology revealed a benign 8 cm right paratubal cyst and a benign 18 cm left serous cystadenoma with papillary excrescences. Conclusions: Pelvic anatomy can be greatly distorted secondary to prior abdominal surgeries or certain pathologies including endometriosis and congenital abnormalities. Ultrasound cannot easily discriminate between intraperitoneal and retroperitoneal ovarian cysts but is often the only preoperative imaging obtained prior to cystectomy. Thus, many retroperitoneal cysts are found intraoperatively resulting in diagnostic and therapeutic challenges. Therefore, general gynecologists must be aware of risk factors associated with abnormal pelvic anatomy and prepared to request intraoperative consultation if needed to ensure optimized patient care and safety.

Development of a gastrocutaneous fistula from a marginal ulcer after repair of duodenal injury with pyloric exclusion

Duodenal trauma is rare but can be associated with significant morbidity and mortality (Pandey et al., 2011) [1]. Adjunct procedures, such as pyloric exclusion, can be performed to assist in surgical repair of these injuries. However, pyloric exclusion can lead to severe long-term complications associated with significant morbidity that can be difficult to repair. A 35-year-old man with a history of duodenal trauma from a gunshot wound (GSW) status post pyloric exclusion and Roux-en-Y gastrojejunostomy presented to the Emergency Department (ED) with complaints of abdominal pain and leakage of food particles and fluid from an open wound around his surgical scar. Computed tomography (CT) scan on admission showed a tract extending from the gastrojejunostomy anastomosis to the skin representing a fistula. Esophago-gastro-duodenoscopy (EGD) reconfirmed a large marginal ulcer that had fistulized to the skin. After nutritional repletion, the patient was taken to the operating room (OR) for takedown of the enterocutaneous fistula and Roux-en-Y gastrojejunostomy, closure of gastrostomy and enterotomy, pyloroplasty and feeding jejunostomy tube placement. The patient was re-admitted after discharge with abdominal pain, vomiting and early satiety. EGD showed gastric outlet obstruction and severe pyloric stenosis which was managed with endoscopic balloon dilation. This case represents the severe and potentially life-threatening complications that may occur after pyloric exclusion with Roux-en-Y gastrojejunostomy. Gastrojejunostomies are prone to marginal ulceration which can perforate if not adequately treated. Free perforations cause peritonitis, but if the perforation is contained it can erode through the abdominal wall creating the rare complication of a gastrocutaneous fistula. Even after restoration of normal anatomy with a pyloroplasty, patients may suffer additional complications such as pyloric stenosis requiring continued intervention.

Paper 21: Functional Outcomes of Primary Ulnar Collateral Ligament Repair with Internal Bracing in Athletes

Objectives: The ulnar collateral ligament (UCL) is the primary restraint to valgus stress in the elbow. Injury to this ligament can occur in the setting of acute trauma as well as chronic overuse as seen in baseball players and other overhead athletes. Injury to the UCL continues to be a major source of morbidity in overhead-throwing athletes, with the incidence of UCL tears increasing dramatically over the past 15 years. UCL reconstruction using palmaris longus or hamstring autograft (also known as Tommy John surgery) has been considered the gold standard for the surgical treatment of symptomatic UCL injuries in overhead athletes for decades. Recently, there has been a renewed interest in UCL repair. In 2016, Dugas et al described the novel use of a collagen-dipped internal brace to augment UCL repair with encouraging biomechanical results from a cadaveric study. To date, only two studies have reported outcomes for this novel approach to UCL repair with internal brace (IB) augmentation, both with encouraging results. It is thought that the main advantages of UCL repair with IB augmentation compared to UCL reconstruction are comparable return to sport rates with a more rapid postoperative recovery, as well as restoration of normal anatomy that eliminates the need for an autograft and the associated complications of graft harvesting. Given the paucity of data examining this new surgical approach, this study seeks to add clinical outcome data for UCL repair to the scientific literature. The goal of this project is to evaluate functional outcomes following primary ulnar collateral ligament repair using internal brace augmentation and to describe new advancements in the surgical technique for this procedure. Methods: Approval was obtained from the Columbia University Irving Medical Center Institutional Review Board. A retrospective review of the electronic medical records of all consecutive patients who underwent medial UCL repair with internal brace augmentation between 2016 and 2022 was performed. All procedures were performed at a single tertiary institution and all patients were under the direct medical care of the senior author. Only patients with a focal UCL injury, such as a distal or proximal avulsion tear, were selected for UCL repair with internal brace augmentation. Evidence of chronic attritional disease, including calcification on MRI, or extensive ligamentous injury were contraindications to UCL repair. Additionally, only patients undergoing primary UCL repair with internal brace augmentation were included; those with prior UCL reconstructions or repairs were excluded as were patients with insufficient clinical follow-up data. Included in the chart review were patient demographics, level of sport, injury characteristics, preoperative imaging findings, operative data, and postoperative clinical outcomes including complications and reoperations. Patient reported outcomes were collected from the Pitch Registry, a national database maintained by Major League Baseball (MLB). Primary outcomes for this study include the ability to return to play (RTP) at the same previous level or higher, the time to return to competition, complications, and reoperations. Results: A total of 56 patients were included in this study (mean age at surgery was 19.5 ± 4.5 years; 55 men and 1 woman). The majority were baseball players (n=52) of which 43 were pitchers, while the remaining athletes played football, wrestled, or competed in Jujitsu. Twenty-eight were high school athletes, 23 played at the collegiate level, 4 played recreationally, and 1 played professionally. Symptoms of UCL injury preceded surgery by an average of 7.5 ± 15.0 months. The UCL was partially torn in 39 patients and fully torn in the remaining 17 patients, and it was torn proximally in 18, distally in 37, and mid-substance in 1 patient. The mean preoperative Kerlan-Jobe Orthopaedic Clinic (KJOC) score was 61.5 ± 15.3, the mean preoperative American Shoulder and Elbow Surgeons (ASES) score was 71.6 ± 14.9, and the mean preoperative Youth Throwing Score (YTS) was 40 ± 14. A concomitant arthroscopic osteophyte debridement and synovectomy was performed in 10 cases and a concomitant ulnar nerve transposition was performed in 4 cases. There were no intra-operative complications. The mean length of follow-up was 12.1 ± 7.1 months. Of the total cohort, 51 (91.0%) patients were able to return to play at an average of 7.8 ± 2.4 months. There were 4 reoperations (7.1%) including a single revision UCL reconstruction, 2 ulnar nerve transpositions, and 1 arthroscopic osteophyte debridement. Conclusions: Primary UCL repair with internal brace augmentation is a viable alternative to UCL reconstruction as supported by a rapid return to play and a low complication rate. There remains a paucity of data examining this encouraging and novel surgical approach. Additional data and analysis examining functional outcomes and optimal patient selection will be critical to address the rising epidemic of UCL injuries in young athletes.

Laparoscopic Wedge Resection of a Cesarean Scar Ectopic Pregnancy at Nine Weeks Gestation

<h3>Study Objective</h3> To demonstrate an approach to laparoscopic wedge resection of a cesarean scar pregnancy (CSP). <h3>Design</h3> Video abstract. <h3>Setting</h3> Tertiary care Centre. <h3>Patients or Participants</h3> This case is of a 40-year-old G6P3, with 3 prior cesarean sections who was referred with a possible ectopic pregnancy at 8+3 weeks gestation after presenting with cramping and irregular bleeding. Following admission to hospital, transvaginal ultrasound revealed a CSP and a type 1 placenta percreta with no bladder involvement. The patient wished for fertility-sparing management which was planned to include pre-operative intragestational methotrexate and uterine artery embolization followed by laparoscopic wedge resection. Before pre-operative interventions could be done, the patient experienced acute vaginal bleeding and she was taken urgently for surgical management. <h3>Interventions</h3> Laparoscopic wedge resection of the CSP. <h3>Measurements and Main Results</h3> Laparoscopy revealed bladder adhesions high over the lower uterine segment and the CSP. Wedge resection of the CSP was successfully achieved with restoration of normal anatomy using a systematic approach to lysis of adhesions as well as intraoperative vascular control using dilute vasopressin and pre-emptive skeletonization of the uterine vessels. Surgical blood loss was 100mL. There were no intraoperative or postoperative complications, and the patient was discharged home post-operative day 1. The patient's beta HCG levels returned to normal within one month. <h3>Conclusion</h3> CSPs account for approximately 4% of all ectopic pregnancies. Management is individualized and often requires a multi-modal approach. This case demonstrates a safe and successful approach to fertility-sparing laparoscopic wedge resection.

Isthmocele endometriosis: the relationship between cesarean section and endometriosis

To present a case of endometriosis within an isthmocele membrane and concomitant diffuse peritoneal endometriosis after cesarean sections. In addition, we describe a unique, color-contrasted surgical repair technique and propose a possible correlation between isthmocele formation and endometriosis. Narrated video article featuring the diagnosis, unique surgical management, and pathological findings of a case of isthmocele endometriosis. Informed consent was obtained from the patient, and all identifiers were removed. University-affiliated hospital. A 44-year-old patient with three prior cesarean sections and a laparoscopic appendectomy, in none of which endometriosis was visualized. She presented with progressive pelvic pain, dysmenorrhea, dyspareunia, and secondary infertility with recurrent embryo transfer failures. The progressively debilitating symptoms started 14 years ago, shortly after her last cesarean section. Magnetic resonance imaging and ultrasound demonstrated a retroverted uterus and a prominent, thin, fluid-filled cesarean scar defect with a residual myometrial thickness of 1.1 mm. A combined hysteroscopic and laparoscopic approach was performed to allow for complete resection of the defect and reconstruction of the myometrium. The bladder was backfilled with indocyanine green dye to help identify its borders. Methylene blue was added to the hysteroscopy irrigation solution to create contrast and assist with the isthmocele identification. Wide excision of the isthmocele was performed, followed by a three-layer closure and excision of all apparent peritoneal lesions using the Aqua Blue Contrast Technique. Restoration of normal anatomy, resection of isthmocele, and resolution of the symptoms. In the pathological assessment, multiple foci of endometriosis were identified within the isthmocele membrane, clearly differentiated from intrauterine endometrial tissue. Additionally, all seven excised peritoneal specimens contained peritoneal endometriosis. Two weeks after the procedure, a transvaginal sonographic scan confirmed a thick anterior uterine wall with a myometrial thickness of 9.2 mm, and the patient reported almost complete resolution of her symptoms. This case demonstrates endometriosis within the isthmocele membrane, with concomitant symptomatic peritoneal endometriosis. We propose a laparoscopic isthmocele excision technique and a three-layer reconstruction, followed by peritoneal endometriosis excision using methylene blue contrast. We suggest a possible link between isthmocele and endometriosis and emphasize the need for wide excision of the isthmocele margins and maintaining clean borders, given the possibility of endometriosis within the isthmocele, which may be a cause or a contributor to the tissue weakness and isthmocele formation.

Fertility-Preserving Surgical Management of a Cesarean Section Scar Ectopic Pregnancy

To demonstrate techniques used for fertility-preserving surgical management of a cesarean scar ectopic pregnancy. A narrated video case report demonstrating techniques and surgical approach. With the increasing number of cesarean deliveries being performed, cesarean scar ectopic pregnancies (CSEP) have an increasing incidence affecting approximately 1 in 2000 pregnancies. CSEP can be associated with serious complications, which include maternal hemorrhage, uterine rupture, and even maternal death. This video highlights a case presentation of a 28-year-old G6P4014 with a history of 4 previous cesarean deliveries who presented with a persistent cesarean scar ectopic pregnancy that had failed previous medical management. This video highlights the techniques that allow for fertility-preservation with restoration of normal anatomy as well as minimizing blood loss with a potentially morbid procedure. Techniques used to allow for fertility preservation with restoration of normal anatomy: 1. Utilization of avascular spaces and identification of critical structures to restore anatomy that is often distorted by the CSEP. 2. Limited use of electrosurgery to allow for adequate postoperative healing. 3. Identification of the endometrial cavity to allow for complete removal of the CSEP and isthmocele repair. Techniques used to minimize blood loss: 1. Intracervical injection of dilute vasopressin. 2. Intrauterine injection of dilute vasopressin (20U in 60 cc of injectable saline). 3. Temporary occlusion of bilateral gonadal vessels using surgical clips. The surgical techniques highlighted in this video allow for the surgical removal of a cesarean scar ectopic pregnancy with concurrent repair of the uterine defect, allowing for restoration of normal anatomy. This is a safe and feasible fertility-preserving option that can be performed using a minimally-invasive approach.

Isolated Upward Rotation of the Fetal Cerebellar Vermis (Blake’s Pouch Cyst) Is a Normal Variant: An Analysis of 111 Cases

Introduction: The objective of the study was to provide more detailed data about fetal isolated upward rotation of the cerebellar vermis rotation (Blake’s pouch cyst) in particular regarding pregnancy outcome. Methods: This is a retrospective study of all cases of fetal isolated upward rotation of the cerebellar vermis (URCV) diagnosed in 3 referral centers in Italy from January 2009 to November 2019. Whenever possible, prenatal magnetic resonance imaging (MRI) was performed and a fetal karyotype was obtained. A detailed follow-up was obtained by consultation of medical records, interview with the parents, and the pediatricians. Results: Our study population included 111 patients with a prenatal diagnosis of isolated URCV made at a median gestational age of 21 weeks +3 days (interquartile range (IQR) 21 + 0–22 + 2). The median brain stem-vermis (BV) angle was 27° (IQR 24–29°). In 37.9% of the cases, a regression of the finding with restoration of normal anatomy was noted at a follow-up scan or at postnatal checks. A BV angle of 25° or less predicted regression with a probability in excess of 90%. MRI was performed in utero or at birth in 101 patients and always confirmed sonographic diagnosis. Fetal CGH array and/or karyotype was available in 97 cases and was always normal, but in 1 case. A postnatal follow-up was available in 102 infants (mean 7 months, range 0–10 years of age) and documented a normal neurologic development in all the cases. Conclusions: Isolated URCV is most likely a normal variant of fetal anatomy without clinical consequences, at least at an early follow-up. A BV angle of 25° or less predicts intrauterine regression of the finding, but the outcome is good in all the cases. When a confident sonographic diagnosis is made, MRI is not mandatory. The risk of a chromosomal anomaly in these cases is probably low.

Identification and treatment of a cervical sinus tract in a patient with 10 years of infertility

To introduce a special case of endometrial cavity fluid (ECF), highlighting the application of hysteroscopy and laparoscopic surgical techniques in the treatment of cervical sinus tract. Narrated video featuring the diagnosis and surgical management of a case of recurrent ECF. Informed consent was obtained from the patient, and approval was granted by the ethics committee of the First Affiliated Hospital of the Wenzhou Medical University. Academic tertiary hospital. A 36-year-old woman, gravida 0, had menstrual spotting for 13 years after abdominal myomectomy of a 104 × 86 × 111-mm myoma on the posterior uterine wall near the cervix. She failed to conceive after her marriage for 10 years, and 5 operations, including hysteroscopy and laparoscopy, were performed to increase pregnancy opportunities. She also underwent invitro fertilization and embryo transfer procedures many times, but failed. Transvaginal sonography preoperatively suggested that ECF sometimes appeared and sometimes disappeared. The local echo of the posterior wall of the cervix was enhanced. A 40-mm cystic dark area was found beside the right ovary, which seemed to connect with the cervical hyperechoic part. Additionally, a solid mass of the right adnexa with abundant blood supply was detected. First, hysteroscopy was performed to explore the ECF. A deep and narrow cervical sinus with a steady stream of accumulated blood overflowed in the lower part of the cervix, and a normal uterine cavity was found. Laparoscopic adhesiolysis and enucleation of the cystic structure that connected to the sinus tract then were performed. Hysteroscopy was repeated to determine the thinnest cervical region by the light transmission test. A horizontal incision was made on the thinnest layer. Scar tissues were removed. The incision was sutured in full layer intermittently and continuously under laparoscopy. The postoperative thickness of the muscular layer in the sinus was confirmed by light transmission test of hysteroscopy. The patient was discharged on the third day after operation, uneventfully. Histopathologic examination showed that the cystic structure and scar tissue contained smooth muscle tissue and were covered by both mucinous columnar epithelium of the cervical canal and endometrial glandular epithelium. Restoration of normal anatomy, removal of uterine effusion, and symptomatic relief. At the 6-month follow-up, the patient's menstrual cycles returned to normal without the recurrence of menstrual spotting. The ultrasound scan also showed a symmetrical uterus without ECF. Patients with ECF who underwent assisted reproductive surgeries were related to the poor prognosis. However, the treatment should be different according to the causes, appearance time, and accumulation amount, including expectant treatment, postponement of embryo transfer, transvaginal aspiration, laparoscopic salpingectomy, or proximal tubal occlusion. For patients with recurrent ECF and/or special appearance on ultrasound, endoscopic examination is necessary. In addition, patients with large myomas at difficult locations required a uniform strategy to reduce the intraoperative and postoperative complications, especially for the nulligravida women.

146 Ligamentization and Remnant Integration: Implications for Scapholunate Reconstruction

Abstract Introduction Scapholunate interosseous ligament (SLIL) injuries are common but remain a therapeutic challenge. Current treatment modalities prioritize restoration of normal anatomy with reconstruction where appropriate. To date, no reconstructive technique has been described that discusses the potential benefit of the preservation of the scapholunate ligament remnant. Little is known about the ‘ligamentization’ of grafts within the wrist. However, a growing body of knee literature suggests that remnant sparing may confer some benefit. In the absence of wrist specific studies, this literature must guide areas for potential augmentation of current surgical practices. Method We conducted a systematic review of the literature using Pubmed, Embase and Medline. Keywords were ‘Ligament’ AND ‘Reconstruction’ AND ‘Remnant’. We identified 366 original studies for title and abstract review. A total of 5 studies were included in the final analysis. Results In 5 animal studies, remnant stump integration resulted in enhanced ligamentization of grafted tissue as measured by vascularity, biomechanics, and proprioception. Conclusions Our review demonstrates a trend towards enhanced early ligamentization in grafts that incorporate the remnant stump. Remnant preservation is not currently performed in SLIL reconstruction and may provide an avenue for enhanced therapies. As such, it is a promising area for further, wrist specific, research.

Recurrent hiatal hernias. To operate or not?

The recurrence of a hiatal hernia after surgical treatment is the most serious and far from resolved problem in this area of surgery. The validity and effectiveness of surgical treatment of recurrent hiatal hernia of the diaphragm remains the subject of clinical research and scientific discussion. The main problems of such interventions are the difficulty of eliminating the anatomical or functional factors that underlie the failure of the primary operation. The stated provisions determine the need for further searches for a solution of this problem. In the period from 2015 to 2020, 61 patients with recurrent hernia of the gastrointestinal orifice of the diaphragm underwent surgical treatment. Indications for the operation were gastroesophageal reflux refractory to drug therapy or anatomical changes that carry the risk of developing life-threatening conditions. In 58 (95.1%) cases, surgery was performed laparoscopically, in 3 (4.9%) through left-side thoracotomy. In 54 (88.5%) cases, complete restoration of normal anatomy with closure of the hiatal opening with prosthetic material is performed. In 7 (11.5%) cases, when the esophagus was shortened, the fundoplication cuff was created in the chest cavity, and the hiatal opening was performed only with its own tissues. Complications occurred in 11 (18.0%) cases (7 pneumothorax, 2 bleeding, 2 perforation of a hollow organ). Long-term results (12-48 months) were evaluated in 57 (93.4% of operated) people. Repeated recurrence of hiatal hernia of the diaphragm was detected in 6 (10.5%) cases. In 44 (77.2%) cases, the natural anatomical position of the abdominal organs was documented. In 7 (12.3%) patients, with a fundoplication cuff formed in the chest, its initial position was ascertained.

1901 Obliterated Rectovaginal Space Dissection

Video Objective Show dissection techniques in a completely obliterated cul-de sac. Setting Stage 4 Endometriosis patient. Interventions Robotic assisted excision of endometriosis, hysterectomy and restoration of normal anatomy. Conclusion Stage 4 Endometriosis causes frozen pelvis and complete distortion of normal anatomy. Restoration of normal anatomy and excision of endometriosis is the goal of surgery in such patients whether or not hysterectomy is performed. It is essential to restore the normal anatomy and identify the key structures before undertaking hysterectomy to avoid inadvertent injuries and also to provide symptomatic relief to the patient. Deeply infiltrative fibrotic endometriosis infiltrates through rectovaginal space and causes complete obliteration of the cul-de sac, displacement of ureters, distorted pelvic side walls and perirectal fossas. The dissection is started by identifying the ureters on each side, develop normal space between the ureter and colon as well as between the rectum and uterosacral ligaments. The instinct is to tackle the midline but a minimally invasive gynecologic surgeon should know that the correct approach is in developing the spaces laterally before dissecting in the midline.

Robotic Resection of Abdominal Wall Endometriosis

Video Objective To describe surgical techniques used to resect abdominal wall endometriosis. Setting The patient is a 49 year old female who presents to a tertiary care academic institution with complaints of cyclic pelvic pain. Interventions Minimally invasive excision of extrapelvic endometriosis. Conclusion The goals of resection of abdominal wall endometriosis are restoration of normal anatomy and adequate excision of pathology in order to decrease risk of recurrence. Robotic excision of abdominal wall endometriosis is feasible with understanding of anatomy and mastery of basic surgical techniques.

Correlation between Radiological Parameters and Functional Outcome of Healed Unstable Fracture Distal Radius after External Fixation

Background: Wrist fractures represent about one-sixth of all fractures seen in emergency department. The goal of treating such fractures is no longer only fracture union, but also the restoration of normal anatomy with early functional recovery, as well as full and painless motion of the wrist. In this prospective study we intend to evaluate the correlation between functional outcome and radiological parameters of the unstable fracture of the distal radius when treated with external fixator.&#x0D; Methods: A hospital based, observational study was conducted at department of Orthopedics, College of Medical Sciences Teaching Hospital, Bharat-pur, Chitwan, during the period of January 2011 to November 2013, 54 patients, 33 male and 21 female, with unstable fracture of the distal end of radius were treated with external fixator and followed for a period of 18 weeks.&#x0D; Results: The clinical and radiological outcome were evaluated on the basis of Modification, by Sar-miento et al., of the Demerit Point system of Gartland and Werley and Sarmiento et al’s modification of Lid-strom’s scoring system respectively at the end of 18 weeks. The clinical result was excellent in 25 cases, good in 19 cases and fair in eight cases. There were 8 (15.4%) excellent, 25 (48.1%) good, 15 (28.8%) fair and 4 (7.7%) poor cases according to radiological scoring.&#x0D; Conclusions: In this study we found no correla-tion between clinical outcome and radiological parameters following external fixation in distal radius fractures.

Defining the “mediolateral widening of tibial plateau” as a guide for reduction in tibial plateau fractures: An Indian perspective

PurposeThe primary aim in fixation of the tibial plateau fractures is the restoration of normal anatomy. Evaluation of the widening of the tibial plateau, which has been linked with adverse long term outcomes, still needs precise markers for quantification. The purpose of this study is to analyze the normal limits of tibial plateau widening in the Indian population in relation to the distal femur in a standardized manner to provide important radiological parameters for the same. MethodsWe retrospectively analyzed electronically archived true AP radiographs of uninjured normal knee joints during one year between 2018 and 2019. We measured the mediolateral width of the articular surface and extraarticular extent of the tibial plateau and compared them with the distal femoral articular and extra-articular extents. The measurements were compared between the male and female groups. ResultsTibial plateau articular width was found to be 4% wider in relation to the distal femoral articular surface. The medial articular rim of distal femur matches closely to the medial articular rim of the tibial plateau. The lateral articular rim of distal femur lies medial to the lateral articular rim of tibial plateau with a mean distance of 3.49 mm. ConclusionsOwing to individual variations in bony extents around the knee, the differential extent of tibial plateau relative to distal femur would be a more reliable parameter than absolute measurements. Medially the articular extent of distal femur matches closely with the articular extent of tibial plateau while the lateral extra-articular extent of distal femur matches closely with the lateral tibial articular extent. Gender-based differences do not significantly affect these two parameters.

37: A 20-centimeter peritoneal inclusion cyst presenting as vaginal prolapse

This video shows the surgical evaluation and excision of a peritoneal inclusion cyst with laparoscopic repair of the pelvic floor. Our case is that of a 44-year-old female referred to urogynecology for pelvic organ prolapse. The patient reported bulge sensation for six months. On examination, a vaginal mass descended four centimeters outside of the introitus. The mass was reducible and unchanged while standing or straining. Dynamic MRI demonstrated a 20-centimeter intraabdominal cystic mass located between the uterus and the rectum and extending into the vagina. Robotic assisted laparoscopic evaluation showed endometriosis and a large peritoneal inclusion cyst extending from the pelvic brim to the rectovaginal septum. After the fluid was drained, redundant peritoneal tissue was excised. The distended posterior vaginal wall was then laparoscopically reduced using interrupted sutures of 2-0 PDS to imbricate the posterior vagina down to the perineal body. Uterosacral ligaments were plicated at the apex of the vagina with interrupted 2-0 PDS, suspending the posterior vaginal apex and uterus. Given the large peritoneal defect from the dissection, a culdoplasty was performed with purse string sutures using 2-0 monocryl. On repeat vaginal exam, restoration of normal anatomy was confirmed. At the six-week post-operative visit, the patient denied further bulge symptoms and had a normal vaginal exam. Pathology revealed benign simple mesothelial cyst without malignancy. We present a unique presentation of a large peritoneal inclusion cyst presenting as vaginal prolapse. Laparoscopic repair can be performed similarly to closing an enterocele. Consideration for laparoscopic repair of a high rectocele can be performed in specific cases when already working laparoscopically to avoid vaginal incisions. Further studies are needed to determine the efficacy of laparoscopic versus transvaginal rectocele repair.

The relationship between gait and functional outcomes in patients treated with circular external fixation for malunited tibial fractures

BackgroundLower extremity fractures have a profound negative effect on a patient’s gait and outcomes. Correction of deformity, and with it normalization of objective gait parameters, may result in better subjective and objective functional outcomes in patients treated with circular external fixation for malunited tibial fractures. AimThe purpose of this study was to investigate the relationships between gait parameters, patient reported outcome measures (PROMs), and health related quality of life measures in patients treated with circular external fixation for the correction of deformity related to tibial malunions. MethodsThis retrospective study included patients with posttraumatic tibial deformities, aged 14–65, with a minimum follow-up of 24 months following deformity correction. Patients with congenital deformities, head injuries, spinal cord injury, neurological disorders, or contralateral lower limb amputation were excluded. Functional outcomes were assessed by the Foot Function Index (FFI); Short Form 12 (SF-12); the EQ 5D; and the ASAMI score. Gait analysis was performed using Dartfish® and the Edinburgh Visual Gait Score (EVGS). The relationships between the EVGS and functional outcome scores were analyzed using Pearsons’ moment correlations with Bonferroni corrections. ResultsEleven patients with a mean age of 42 (range 23–57) were analyzed. The mean EVGS was 2.6 ± 2.1, the mean FFI 29.6 ± 33.4, the mean EQ5 Index Value 0.7 ± 0.2, the mean EQ5 VAS 85.4 ± 19.5, the SF12 mean Physical Component Score (PCS) 46.7 ± 11.1, and the mean Mental Component Score (MCS) 55.2 ± 7.5. The following relationships were strong and significant: EVGS and FFI (r = 0.7; P = 0.02), EVGS and PCS (r = −0.82; P = 0.02), and FFI and EQ5 (r = −0.79, P = 0.05). SignificanceThe results of this study suggest that correction of deformity with realignment and restoration of normal anatomy was associated with improved functional outcomes and physical well-being. Patient reported quality of life is strongly associated with patient perceived functional outcome, but not with objective gait parameters.

This is a prospective study conducted over a period of 2 years and 1 month (from September 2005 to October 2007). 60/117 (52.17%) patients who had laparoscopy for infertility at GMH had endometriosis. 60 patients operated for endometriosis at SHC and 40 patients managed at Anu Infertility Centre during the same period are also included in this study. All the 60 patients underwent operative laparoscopy for endometriosis. Adhesiolysis, electrocautery of surface endometriosis of the ovary, enucleation of endometriotic cyst, mobilization of ovary from uterus and pouch of Douglas and restoration of normal anatomy were carried out. Treatment interventions: Therapeutic hysteroscopy and laparoscopy, medical treatment by various ovulation induction protocols, monitoring by follicular sonography followed by pregnancy management were done in these women. Results: GMH—Seventeen 17 out of 18 coming for follow up conceived, 14 following ovulation induction and 3 after COH + IUI, by one year at GMH. SHC—14 out of 18 patients coming for follow up at the end of one year conceived, following ovulation induction 6, COH + IUI-3, IVF-3 and spontaneous 2. ANU—Out of 11 conceptions, COH + IUI resulted in 6, IVF in 4, spontaneous in 1—by one year. Pregnancy outcome: GMH: Ten delivered, Triplets in one, missed abortion two, emergency laparotomy in one. Pregnancy is continuing in 4. SHC: Eight patients delivered. Pregnancy is continuing in 4 patients. Ectopic-1, missed abortion-1. ANU: Five patients delivered. Pregnancy is continuing in 3 women, missed abortion-2, second trimester abruption-1. Discussion: The conception rate was 50% at the end of 6 months follow up <span s
