BACKGROUND
Dense adhesion due to severe endometriosis between the posterior cervical peritoneum and the anterior sigmoid or rectum obliterates the cul-de-sac and distorts normal anatomic landmarks. Surgery for endometriosis is associated with severe complications, including ureteral and rectal injuries, as well as voiding dysfunction. It is important to develop the retroperitoneal avascular space based on precise anatomical landmarks to minimize the risk of ureteral, rectal, and hypogastric nerve injuries. We herein report the anatomical highlights and standardized and reproducible surgical steps of total laparoscopic hysterectomy for posterior cul-de-sac obliteration.
OPERATIVE TECHNIQUE
We approach the patient with posterior cul-de-sac obliteration using the following five steps. Step 1: Preparation (Mobilization of the sigmoid colon and bladder separation from the uterus). Step 2: Development of the lateral pararectal space and identification of the ureter. Step 3: Isolation of the ureter. Step 4: Development of the medial pararectal space and separation of the hypogastric nerve plane. Step 5: Reopening of the pouch of Douglas.
CONCLUSION
Surgeons should recognize the importance of developing the retroperitoneal avascular space based on precise anatomical landmarks, and each surgical step must be reproducible.

An 8-month-old intact male domestic shorthair cat was referred to the Emergency Service of the Veterinary Teaching Hospital (VTH) of the Department of Veterinary Science of the University of Parma (Italy) from the Parma municipal multi-cat shelter, during the winter season (January 2023), for lethargy, anorexia, hypothermia, and hypoglycemia. At the VTH, upon cardiologic examination, an increase in heart rate, under normal blood pressure conditions, was detected. Signalment, clinical history, basal metabolic panel (BMP), ultrasound investigations, and cytological findings were all consistent with a diagnosis of feline infectious peritonitis (FIP). FIP was confirmed in the effusive abdominal fluid by a molecular genetic test (real-time PCR for feline coronavirus RNA). The molecular genetic investigation also detected an FCoV gene single-nucleotide mutation: biotype M1058L. At necropsy, an effusive collection was recorded in the abdomen, thoracic cavity, and pericardium sac. White parenchymal nodules, of about 1 mm diameter, were found on the surface and deep in the lungs, liver, kidneys, and heart. Histopathology revealed the typical FIP pyogranulomatous vasculitis and IHC confirmed the presence of the FIP virus (FIPV) antigen. The most relevant histopathological finding was the myocarditis/myocardial necrosis associated with the presence of the gene-mutated FCoV (M1058L biotype). This is the first case of myocarditis in a cat positive for the FCoV/FIP M1058L biotype. Further studies are necessary to support the mutated FCoV M1058L biotype, as an uncommon, but possible, causative pathogen of myocarditis in FCoV/FIP-positive cats. Studies including several FCoV/FIP M1058L-positive cases could allow us to make a correlation with heart gross pathology, histopathology, and immunolocalization of the FCoV/FIP M1058L biotype in the myocardium. The investigation will potentially allow us to determine the effective tropism of the FCoV/FIP M1058L biotype for myocardiocytes or whether myocardiocyte lesions are evident in the presence of concomitant causes related to the patient, its poor condition, or external environmental distress such as cold season, and whether the aforementioned concomitant events are correlated.

Incidentally Diagnosed Low-Grade Primary Peritoneal Serous Carcinoma Within the Umbilical Hernia Sac in a Male: A Report of an Extremely Rare Case and Review of the Literature.
Primary peritoneal serous carcinoma (PPSC) is a rare tumor that develops in the peritoneum. PPSC originates from embryonic nests of Müllerian cells in the peritoneum, which are also present in the epithelium of the ovary. This similarity explains the histopathological resemblance between PPSC and low-grade serous ovarian carcinoma. While PPSC primarily affects women, it is an extremely rare occurrence in males, and it is believed that the significant difference in diagnosis rates between males and females is due to the inhibition of Müllerian system growth by substances produced by male Sertoli cells. These substances are present at higher levels in males, which may prevent the development of Müllerian system-derived tumors in men. We describe a 65-year-old male patient who presented for elective bariatric surgery and umbilical hernia repair, and an incidental finding of low-grade PPSC was made based on hernia sac pathology. The patient underwent further management, including tumor debulking and hyperthermic intraperitoneal chemotherapy (HIPEC), with positive outcomes. Long-term follow-up and oral letrozole treatment are planned.

KEY CLINICAL MESSAGE
This report emphasizes the significance of acknowledging infrequent yet severe complications such as bowel perforation and transanal protrusion post ventriculoperitoneal shunt (VPS) surgery. VPS patients should be observed for atypical indicators and manifestations that could suggest the presence of such complications, even in the lack of traditional clinical signs of peritonitis or bowel perforation.
ABSTRACT
Placing an intracranial shunt, may be a reasonable approach to decrease the complications of hydrocephalus and it can be done either simultaneous to cranioplasty or not. Ventriculoperitoneal shunts were first proposed in 1905 and has been used since. Similar to any other procedure, there are different complications to this surgery. Abdominal complications, including peritoneal pseudocysts, intestinal volvulus, protruding in hernial sac or extrusion through vagina, scrotum, umbilicus or gastrointestinal tract, are rare but according to previous studies happen in 5%-47% of cases. Bowel perforation is a rare complication and can happen in 0.01%-0.07% of patients. It's also worth mentioning that only 25% of patients with bowel perforation experience the classic clinical symptoms of peritonitis or bowel perforation. This particular complication should not be overlooked since it can cause a high mortality rate of 15%. Here we present a case of transanal protrusion of ventriculoperitoneal shunt after an asymptomatic bowel perforation, in an adult who has undergone surgery after a traumatic brain injury. The patient has undergone surgery and lastly the shunt was manually removed from anus. He was monitored for 3 days and eventually discharged.

INTRODUCTION AND IMPORTANCE
Uterine rupture is a rare condition that typically occurs in a scarred uterus and can happen during late pregnancy, labor, or the early postpartum period. Since most cases are seen in patients with a history of cesarean surgery, the anterior lower uterine segment is the most affected area. Most patients present with acute symptoms that compromise the fetus and the mother in a life-threatening manner.
CASE PRESENTATION
We present a case of uterine rupture with subacute symptoms occurring in the second trimester, which is extremely rare. The patient was a stable second-trimester multiparous woman with chronic abdominal pain, but without any signs of peritoneal bleeding or instability. No history of previous cesarean section was present, and she had recently undergone a non-complicated hysteroscopic polypectomy. Transabdominal and transvaginal ultrasounds were performed, revealing a significant full-thickness myometrial defect in the posterior uterine lower segment. This defect allowed the amniotic sac to protrude into the posterior cul-de-sac. No abdominopelvic hematoma was detected. These findings were confirmed in an urgent MRI, and the patient underwent a laparotomy during which a significant full-thickness defect was discovered at the posterior of the uterus. As it was impossible to continue the pregnancy, the fetus was surgically removed and then prepared using multiple layers.
CLINICAL DISCUSSION
The difference between our case and the previously reported one is in the aspect of gradual stable presentation and lacks of vaginal bleeding.
CONCLUSION
Previous hysteroscopy carries a risk for future pregnancy complications, such as uterine rupture.

BACKGROUND
Metastatic germ cell tumors (GCTs) involving body cavity effusions and cerebrospinal fluid (CSF) are rare. Diagnosis is challenging because of limited morphological and clinicopathological information in the literature.
METHODS
A database search of our institution from 1990 to 2024 identified 27 cases of metastatic GCTs, comprising five pediatric and 22 adolescent and adult patients, in serous cavities or the CSF, including peritoneal (15), pleural (nine), CSF (two), and pericardial (one) fluid.
RESULTS
The most common primary site was the testis (n = 10), followed by the ovaries (n = 7), mediastinum (n = 4), retroperitoneum (n = 3), pineal gland (n = 2), and sacrum/coccyx (n = 1). The primary tumors in 14 patients were mixed GCTs (six with a seminoma component), followed by immature teratomas (six), yolk sac tumors (three), embryonal carcinomas (two), pure seminomas (one), and postpubertal teratomas (one). The median interval between primary tumor diagnosis and diagnosis of fluid positivity was 7 months (range: 0-134 months). In nine cases, the malignant fluid was diagnosed simultaneously with or within 1 month of the primary tumor. GCT subtyping was performed on 23 of the 27 cytological specimens. Twenty-four patients (89%) also had metastases to other sites. Thirteen patients died of the disease (48%), with a median survival time of 4 months.
CONCLUSIONS
Metastatic GCTs in serous effusions and CSF are often associated with disseminated disease and poor prognosis. Subtyping can be performed by cytomorphology combined with immunohistochemistry.

INTRODUCTION AND IMPORTANCE
Diverticula are sac-shaped formations resulting from the inward folding of the intestinal wall's lining. While they predominantly occur in the colon, they can manifest in other parts of the gastrointestinal tract, with jejunal diverticulum being the most prevalent. Symptoms are infrequent in most cases, and when they do occur, intestinal perforation is the most severe complication. In such instances, prompt surgical intervention is imperative, typically entailing the excision of the affected intestinal segment, followed by a end-to-end anastomosis.
CASE PRESENTATION
A 75-year-old female patient presented at the emergency department with sharp abdominal pain. Imaging revealed the presence of perforated jejunal diverticula. Diagnostic laparoscopy confirmed a perforated jejunal diverticulum along with generalized peritonitis and multiple diverticula in the same region. Consequently, we performed a segmental intestinal resection and anastomosis.
CLINICAL DISCUSSION
Jejunal diverticulosis, a rare condition primarily affecting the elderly, is found in 0.5-2.3 % of imaging studies. Although its exact cause remains elusive, potential contributing factors include abnormal intestinal movements and elevated gut pressure. Symptoms are generally vague, such as abdominal discomfort. Diagnosis often occurs incidentally during imaging, leading to a high mortality rate when complications occurs. While computed tomography (CT) scans are useful for detecting intestinal wall protrusions, definitive diagnosis typically requires laparoscopy or laparotomy. Treatment varies based on symptoms and complications, with surgery often necessary for perforations or when medical treatment fails.
CONCLUSION
Jejunal diverticulosis is often asymptomatic or displays non-specific symptoms. Timely diagnosis and prompt surgical intervention in case of perforation is crucial.

Amyand's hernia is defined as the presence of an appendix contained within an inguinal hernia. An inguinal hernia is the protrusion of a small or large bowel through a peritoneal defect of the groin. In rare cases, the appendix can become incarcerated or strangulated within the hernia, cutting off the blood supply to the organ. If incarcerated, the appendix is at risk for strangulation, which can lead to rupture and cause worsening of symptoms and/or collapse. We report a case of a 76-year-old male with a history of inguinal hernia repair 30 years prior, who presented with 30 days of intermittent right lower quadrant pain and unintentional weight loss. He required emergent treatment and management. This case underscores the challenge of diagnosing concurrent inguinal hernia and appendicitis and places an emphasis on timely intervention. Treatment options vary based on the appendix's apparent condition within the hernia sac. Despite the complications, including additional drainage site and enterocutaneous fistula, the patient was discharged in stable condition. This case contributes insights into managing complex inguinal pathologies, particularly in the geriatric population.

Fertility and Sterility Apr 2024To present the laparoscopic management of heterotopic cesarean scar pregnancy and discuss other treatment options.
OBJECTIVE
To present the laparoscopic management of heterotopic cesarean scar pregnancy and discuss other treatment options.
DESIGN
Surgical video article. The Institutional Ethics Committee approved the video reproduction.
SETTING
Tertiary referral to a university hospital PATIENT: A 29-year-old woman with spontaneous heterotopic cesarean scar pregnancy presented for vaginal spotting. Ultrasound revealed two gestational sacs at 7 weeks and 6 days of gestation with fetal cardiac activity. One sac was in a normal intrauterine (IU) location, and the other was in a previous cesarean section scar.
INTERVENTIONS
Scar pregnancy was excised laparoscopically, preserving IU pregnancy. No additional measures were taken to reduce bleeding. The bladder was filled with 150 cc isotonic to determine its boundaries. The peritoneum was dissected away from the cervix. After removing the ectopic pregnancy material, the myometrial defect was excised. The uterine wall was closed in three layers using 2-0 V-Loc sutures.
MAIN OUTCOME MEASURES
Ongoing IU pregnancy after laparoscopic removal of cesarean scar pregnancy and term delivery.
RESULTS
The procedure was completed in 67 minutes. Total blood loss was <100 cc. The ongoing pregnancy follow-up was uneventful. Delivery was planned for the 37th-38th weeks. Although instructed to visit immediately after experiencing pain, the patient arrived after the 38th week and reported having pain for 2 days. During the cesarean section, a rupture was observed at the previous incision site, which was fortunately incomplete. A healthy male infant (weight, 3,210 g; Apgar score, 9/10) was delivered.
CONCLUSIONS
The most common approach for heterotopic scar pregnancy is embryo reduction with potassium chloride injection. However, the mass persists in the scar area, resulting in complications associated with excessive bleeding during a cesarean section in approximately half of cases. Moreover, almost all published cases of embryo reduction resulted in premature births before week 36. Considering the present case, laparoscopic surgery may be appropriate for managing heterotopic cesarean scar pregnancy by preserving IU pregnancy.

INTRODUCTION/IMPORTANCE
Peritoneal encapsulation (PE) is a rare congenital anomaly characterised by the presence of an accessory peritoneal membrane which encases part of the small bowel. Typically, this remains asymptomatic, however; in rare cases, a person may present with symptoms suggestive of a small bowel obstruction.
CASE PRESENTATION
Here we present a case of a 58 year old gentleman with congenital PE causing a bowel obstruction which was revealed on commuted tomography scan. He required a laparotomy and excision of the accessory sac.
CLINICAL DISCUSSION
Pre-operative diagnosis of PE can be challenging. It can present as a bowel obstruction with unique features including asymmetric distension of the abdomen on clinical exam and cocoon-like cluster of small bowel on imaging.
CONCLUSION
Congenital PE is a rare cause of bowel obstruction and should be considered early in patients presenting with symptoms of bowel obstruction without previous abdominal surgery.
