Accidental identification of peritoneal encapsulation during an autopsy after a car accident.

Peritoneal encapsulation is a rare congenital pathological condition. Typical of this pathology is the presence of an accessory peritoneal flap that encloses the entire mass of the small intestine. Subjects with this condition often do not show symptoms and, in most cases, finding of it is accidental. We report a case of peritoneal encapsulation, not previously identified and found during an autopsy; the deceased, positive for HIV and affected by a Kaposi's sarcoma, died following a road accident. Unlike other cases in the literature, the peritoneum encapsulated all abdominal organs and not only small intestines. Notwithstanding, there were no signs of intestinal ischaemia or intestinal obstruction.

The significance of post-radiotherapy parametrial involvement and the necessity of parametrial resection in locally-recurrent or persistent cervical cancer developed after radiotherapy.

OBJECTIVE: To retrospectively evaluated the prognostic significance of post-radiotherapy parametrial involvement (PMI), the necessity of parametrial resection, and the optimal salvage surgery in locally recurrent or persistent cervical cancer developed after radiotherapy. METHODS: Patients who developed recurrent or persistent cervical cancer in a previously irradiated field and were subsequently treated with salvage surgery were identified, and the prognostic impact of post-radiotherapy PMI on patient's survival was first investigated. Then, the optimal salvage surgery for patients with post-radiotherapy PMI as well as the predictors for post-radiotherapy PMI were evaluated. RESULTS: A total of 60 patients underwent salvage surgery for recurrent or persistent diseases. Of these, 21 (35.0%) showed post-radiotherapy PMI (PMI-group). Patients in PMI-group showed significantly shorter progression-free survival (PFS) than those in non-PMI-group (p = 0.01). In both PMI-group and non-PMI-group, PFS was affected by the completeness of salvage surgery. In non-PMI-group, less radical surgery achieved similar therapeutic efficacy to more radical surgery (3-year PFS rates: 62.5% versus 54.1%, p = 0.91). In contrast, in PMI-group, not less radical surgery but more radical surgery achieved curative therapeutic efficacy (3-year PFS rate: 0% versus 28.9%). Maximum tumor diameter, deep stromal invasion, and LVSI were found to be predictors of post-radiotherapy PMI. CONCLUSION: Post-radiotherapy PMI is an indicator of short survival after salvage surgery in patients with locally recurrent or persistent cervical cancer developed after radiotherapy. Both less radical and more radical surgery have curative therapeutic efficacies in patients without post-radiotherapy PMI, if the tumor could be resected with an adequate surgical margin. Thus, hysterectomy type should be tailored to the risk for post-radiotherapy PMI.

The International Pediatric Endosurgery Group Evidence-Based Guideline on Minimal Access Approaches to the Operative Management of Inguinal Hernia in Children.

Introduction: Minimally invasive surgery (MIS) for inguinal hernia repair (IHR) in children has been reported for more than two decades. The International Pediatric Endosurgery Group (IPEG) Evidence-Based Review Committee chose MIS IHR as the inaugural topic for review and presentation at the 2016 IPEG annual meeting. Materials and Methods: English language articles published between January 1, 2009, and December 31, 2015, were reviewed and included in this evidence-based review after searching PubMed, Cochrane Reviews, ClinicalTrials.gov, Google Scholar, and EMBASE. Results: Level 1a and 1b evidence supports the recommendations that operative time for bilateral IHRs should be considered shorter and postoperative complications rates should be considered lower in MIS repair over open. Recurrence rates are similar between the two methods (level 1a and 1b evidence). No level 1 evidence exists to support one MIS technique over another or that operating on a detected contralateral patent processus vaginalis during laparoscopy makes any difference in long-term outcome to the patient. Conclusions: The advantages of lower postoperative complications and shorter operative times have been found in studies of surgeons experienced in MIS repair and differences were small. The evidence in this review supports that MIS repair is a safe, effective method of IHR with proper training and mentorship.

Congenital peritoneal encapsulation: A review and novel classification system.

Congenital peritoneal encapsulation (CPE) is a very rare, congenital condition characterised by the presence of an accessory peritoneal membrane which encases a variable extent of the small bowel. It is unclear how CPE develops, however it is currently understood to be a result of an aberrant adhesion in the peritoneal lining of the physiological hernia in foetal mid-gut development. The condition was first described in 1868, and subsequently there have been only 45 case reports of the phenomenon. No formal, systematised review of CPE has yet been performed, meaning the condition remains poorly understood, underdiagnosed and mismanaged. Diagnosis of CPE remains clinical with important adjuncts provided by imaging and diagnostic laparoscopy. Two thirds of patients present with abdominal pain, likely secondary to sub-acute bowel obstruction. A fixed, asymmetrical distension of the abdomen and differential consistency on abdominal palpation are more specific clinical features present in approximately 10% of cases. CPE is virtually undetectable on plain imaging, and is only detected on 40% of patients with computed tomography scan. Most patients will undergo diagnostic laparotomy to confirm the diagnosis. Management of CPE includes both medical management of the critically-unstable patient and surgical laparotomy, partial peritonectomy and adhesiolysis. Prognosis following prompt surgical treatment is excellent, with a majority of patients being symptom free at follow up. This review summarises the current literature on the aetiology, diagnosis and treatment of this rare disease. We also introduce a novel classification system for encapsulating bowel diseases, which may distinguish CPE from the commoner, more morbid conditions of abdominal cocoon and encapsulating peritoneal sclerosis.

Peritoneal Encapsulation - A Rare Cause of Small Bowel Obstruction.

Peritoneal encapsulation (PE) is a rare anatomic anomaly which occurs due to an accessory peritoneal sac covering the small bowel which can cause chronic recurrent abdominal pain and even small bowel obstruction, most often in children or patients with no previous surgical history. The diagnosis is usually made during surgery, but recently it has been suggested that mindful examination of the abdominal CT may be helpful in considering PE beforehand. We present the case of a 21-year old patient who was admitted due to intense abdominal pain, asymmetrical abdominal distension, air fluid levels on the abdominal X-ray, but no specific findings on the abdominal CT. He underwent emergency surgery and PE was found and the peritoneal sac was excised. The postoperative course was uneventful. Histopathologic examination of the specimen confirmed the diagnosis. PE is often misdiagnosed as abdominal cocoon or sclerosing encapsulating peritonitis, but it is a pathology with a much lower rate of recurrence and postoperative complications, which can be treated successfully if the surgeon is aware of this pathology when making the differential diagnosis.

Peritoneal encapsulation: a rare cause of small bowel obstruction.

Peritoneal encapsulation syndrome (PES) is a rare cause of small bowel obstruction (SBO) in patients with no prior history of abdominal surgery. First described by Cleland in 1868, PES is a congenital condition characterised by small bowel encasement in an accessory, but otherwise normal peritoneal membrane. 1 2 A result of abnormal rotation of the midgut during early development, the condition causes fibrous encapsulation of the intestines, thus preventing bowel distention.3 While preoperative diagnosis is difficult, several case reports have described clinical and imaging signs that can help clinicians with not only recognising the condition but also preparing appropriately for perioperative discovery of anatomical variants. 3 4.

[Pathologies of peritoneo-vaginal canal in pediatric surgery at the teaching hospital Gabriel Touré]. / Les Pathologies du Canal Peritoneo-Vaginal en Chirurgie Pediatrique du CHU Gabriel Toure.

The closure anomalies of the peritoneal-vaginal canal include several clinical entities, which are at the origin of various symptomatology. OBJECTIVE: To study the anatomo-clinical and therapeutic aspects of pathologies of the peritoneal-vaginal canal. MATERIALS AND METHOD: This was a prospective study from January 1st to December 31st, 2015 carried out in the pediatric surgery department of University Hospital Gabriel Touré. It covered all children aged 0-15 years old with a pathology of the peritoneal-vaginal canal operating in the department during the study period. This study did not include cases that were not operated on or not seen during the study period. RESULTS: During the study period, 2,699 children were treated in pediatric surgery, of which 150 cases of pathology of the peritoneal-vaginal canal had a hospital frequency of 5.5%. The average age was 3.25 ± 9.63 years. The sex ratio was 14. The reason for consultation was intermittent or permanent inguinal or inguino-scrotal swelling in all children. The pathology was discovered by the parents during the pushing efforts in 46.7%. Inguino-scrotal swelling was found on physical examination in 40% of cases. The right side was reached in 60% of the cases. Hernia accounted for 80.6% of these pathologies. We recorded 31 cases of strangulation and 11 cases of craze. Immediate operative follow-up was simple in 92% of patients. This rate was 96% after 6 months. CONCLUSION: Pathologies of the peritoneal-vaginal canal are very common in pediatric surgical practice. The first place of these pathologies is occupied by hernia. They preferentially affect male infants.

Les anomalies de fermeture du canal péritonéo-vaginal (CPV) regroupent plusieurs entités cliniques qui sont à l'origine d'une symptomatologie variée. OBJECTIF: étudier les aspects anatomo-cliniques et thérapeutiques des pathologies du canal péritonéo-vaginal. MATÉRIELS ET MÉTHODE: il s'agissait d'une étude prospective du 1er Janvier au 31 Décembre 2015 réalisée dans le service de chirurgie pédiatrique du CHU Gabriel Touré. Elle a porté sur tous les enfants de 0-15 ans présentant une pathologie du canal péritonéo-vaginal opérés dans le service pendant la période d'étude. N'ont pas fait partie de cette étude, les cas non opérés et ou non vus pendant la période d'études. RÉSULTATS: Durant la période d'étude 2699 enfants ont été pris en charge en chirurgie pédiatrique dont 150 cas de pathologies du canal péritonéo-vaginal soit une fréquence hospitalière de 5,5%. L'âge moyen était de 3,25± 9,63 ans. Le sexe ratio était de 14. Le motif de consultation était la tuméfaction inguinale ou inguino-scrotale intermittente ou permanente chez tous les enfants. La pathologie a été découverte par les parents lors des efforts de poussées dans 46,7%. La tuméfaction inguino-scrotale a été retrouvée à l'examen physique dans 40% des cas. Le côté droit était atteint dans 60% des cas. La hernie a représenté 80,6% de ces pathologies. Nous avons enregistré 31 cas d'étranglement et 11 cas d'engouement. Les suites opératoires immédiates ont été simples chez 92% des patients. Ce taux était de 96% après 6 mois. CONCLUSION: Les pathologies du CPV sont très fréquentes dans la pratique chirurgicale pédiatrique. La première place de ces pathologies est occupée par la hernie. Elles touchent préférentiellement les nourrissons de sexe masculin.

Peritoneal encapsulation - an unexpected cause of acute intestinal obstruction.

Peritoneal encapsulation (PE) is a rare congenital anomaly that is formed due to an accessory peritoneal layer encapsulating the small bowel. Kinking of bowel within the accessory peritoneal layer or adhesions between the bowel loops and the peritoneal layer causes symptoms ranging from colicky abdominal pain to rarely intestinal obstruction. Cleland was the first person to have reported this condition as early as 1868 and since then only around 30 cases have been reported. Here, we present a case of acute intestinal obstruction in a 22-year-old woman. Imaging showed dilated bowel loops confined to the centre of the peritoneal cavity. Intraoperatively it was seen to be a case of peritoneal encapsulation. The small intestine was freed and accessory layer excised. This report is to demonstrate this rare congenital anomaly.

Imaging of the pediatric peritoneum, mesentery and omentum.

The normal peritoneal structures, including the mesenteries and the omenta, are only a few cell layers thick and are visible on imaging based upon the tissues (e.g., fat) and structures (e.g., blood vessels and lymph nodes) contained within them. These structures become more visible and change in appearance when involved by pathological processes. In this pictorial essay, we discuss the normal anatomy of the various abdominopelvic peritoneal structures and illustrate numerous developmental and acquired diagnoses that involve these structures in the pediatric and young adult population.

[Recent advances in miR-200c and fibrosis in organs].

In the fibrosis and pterygium of lung, liver, kidney, peritoneum or skin, miR-200c was aberrantly expressed. It has been shown that the regulatory effect of miR-200c on fibrosis in organ was involved in TGF-ß-mediated epithelial-mesenchymal transition. The abnormal level of miR-200c in serum may be a basis for early diagnosis of lung fibrosis. Furthermore, miRNA mimics, miRNA agomir, and miRNA inhibitor are potential therapeutic tools for fibrosis. In present review, we summarize the recent progress in relevant studies on the expression and regulatory function of miR-200c and focus on its role in diagnosis, treatment, and prognosis of fibrosis in organ.

Peritoneal encapsulation; a rare cause of bowel obstruction.

Peritoneal encapsulation is a rare congenital cause of bowel obstruction in children. We present the case of a 12-year-old male with severe dehydration and recurrent episodes of vomiting. This pathology should be considered in cases of bowel obstruction with a virgin abdomen.

Abdominal Pain due to a Wandering Liver.

Wandering liver syndrome is an extremely rare congenital disorder. It is mainly diagnosed within the first years of life. Herein we report the case of a 40-year-old woman with hepatoptosis due to the absence of anatomical peritoneal attachments of the liver. Surgical treatment consisted in inserting the floppy right lobe of the liver in a subphrenic retroperitoneal pouch. This original technique provided excellent postoperative result.

Cysts of the canal of Nuck: A rare sonographic diagnosis.

The canal of Nuck is a remnant of a peritoneal evagination associated with the round ligament in women. Rarely, the canal of Nuck can remain patent allowing for development of cysts. These cysts are difficult to diagnose due to their rare incidence and because they are often mistaken for other causes of inguinal pain in women. This case series of three women presenting with groin or labial masses highlights the role of sonography as the primary imaging modality in the diagnosis of canal of Nuck cysts. © 2016 Wiley Periodicals, Inc.

Relationship between Undescended Testis Position and Prevalence of Testicular Appendices, Epididymal Anomalies, and Patency of Processus Vaginalis.

OBJECTIVES: To assess the incidence of testicular appendices (Tas), epididymal anomalies (EAs), and processus vaginalis (PV) patency in patients with undescended testis (UT) according to testicular position and to compare them with human fetuses. METHODS: We studied 85 patients (108 testes) with cryptorchidism and compared the features with those of 15 fetuses (30 testes) with scrotal testes. We analyzed the relationships among the testis and epididymis, patency of PV, and the presence of TAs. We used the Chi-square test for statistical analysis (p < 0.05). RESULTS: In 108 UT, 72 (66.66%) had PV patent, 67 (62.03%) had TAs, and 39 (36.12%) had EAs. Of the 108 UT, 14 were abdominal (12.96%; 14 had PV patency, 9 TAs, and 7 EAs); 81 were inguinal (75%; 52 had PV patency, 45 TAs, and 31 EAs), and 13 were suprascrotal (12.03%; 6 had PV patency, 13 TAs, and 1 EAs). The patency of PV was more frequently associated with EAs (p = 0.00364). The EAs had a higher prevalence in UT compared with fetuses (p = 0.0005). CONCLUSIONS: Undescended testis has a higher risk of anatomical anomalies and the testes situated in abdomen and inguinal canal have a higher risk of presenting patency of PV and EAs.

Nonobliteration of the Processus Vaginalis. Sonography of Related Abnormalities in Children.

The objective of this pictorial essay is to systematically classify processus vaginalis­ related disorders in the light of embryology and present illustrative sonograms with corresponding diagrams. Failure of the processus vaginalis to obliterate during gestation results in a wide spectrum of anomalies, including communicating and noncommunicating hydroceles and inguinal and inguinoscrotal hernias, along with other related disorders of the genital system. There are varying classifications in the literature regarding the aforementioned entities. Proper and timely diagnosis of these entities is essential, given the differences in treatment. Although physical examination can narrow the differential diagnosis, sonography plays an essential role in establishing the diagnosis.

Laparoscopic Appendectomy for Chronic Right Iliac Fossa Pain: Correlating Histology with Outcome.

BACKGROUND: Chronic right iliac fossa (CRIF) pain in children is associated with repeated hospital attendance, inconclusive investigations, and missed school days. There is increasing evidence for the role of laparoscopic appendectomy for the management of CRIF pain. However, currently there is no substantial evidence to correlate histological changes identified in the appendixes removed with resolution of pain. METHOD: This study collected prospective data for a single surgeon's series of laparoscopic appendectomy performed for CRIF pain between 2003 and 2014. RESULTS: Forty patients with a median age of 13 years (range 5-19 years) underwent laparoscopic appendectomy for CRIF pain. Twenty-nine patients (73%) had macroscopically normal appendixes, but histological changes were identified in 28 patients (70%). Other findings at laparoscopy included gynecological pathology (ovarian/para-ovarian cysts), unfixed mobile caecum, and a well-defined peritoneal band extending from the caecum to the anterolateral abdominal wall (caeco-peritoneal band). Patients were followed up for a median of 2 months (range 1-15 months). All patients reported resolution of CRIF pain. DISCUSSION: Laparoscopic appendectomy appears to be an effective treatment for CRIF pain, while also providing the opportunity to diagnose and treat potential sources of CRIF pain other than the appendix. Consistent with the literature, a small number of patients appear to have resolution of pain, despite no histological change being identified in the appendix removed and no other pathology having been identified. The same histological changes commonly seen have also been demonstrated in appendixes removed incidentally. Caution therefore should be applied when interpreting the significance of histological changes seen.

Comparison of Two Techniques of Laparoscopy-Assisted Peritoneal Vaginoplasty.

Neovagina creation is essential for patients with the Mayer-Rokitansky-Kuster-Hauser syndrome. We compared a technique involved the pushing down of the peritoneum with the technique of separating the peritoneum for laparoscopy-assisted peritoneal vaginoplasty. We collected patients with congenital absence of vagina who underwent laparoscopy-assisted peritoneal vaginoplasty of the First Affiliated Hospital of Zhengzhou University between January 2011 and May 2013. The 2 surgical groups (pushing group and separating group) were compared for various parameters. The values of the following parameters were significantly lower for the pushing group compared with the separating group: mean operating time (78 ± 13 minutes vs 135 ± 28 minutes), mean duration of hospitalization (12.9 ± 2.7 days vs 18.0 ± 3.8 days), mean cost of hospitalization (14 016 ± 1640 RMB vs 18 783 ± 2143 RMB), requirement for a drainage tube (4% vs 27%; χ(2) = 8.864), requirement for analgesic drugs (20% vs 40%; χ(2) = 3.977), and postoperative rehospitalization (3.3% vs 10.0% at 2 months and 6.7% vs 26.7% at 6 months; χ(2) = 4.268 and 5.196). Mean values for blood loss (57 ± 19 mL vs 66 ± 20 mL), time to pass gas (21 ± 4 hours vs 23 ± 7 hours), and length of the reconstructed vagina (9.0 ± 0.4 cm vs 8.9 ± 0.5 cm) were not significantly different between the 2 groups. In addition, mean postoperative Female Sexual Function Index score did not differ significantly between the 2 groups or among the 2 groups and a control group (27.0 ± 4.8 vs 26.7 ± 5.2 vs 27.9 ± 4.5; p > .05). The technique involving pushing down of the peritoneum offers advantages of reduced cost, complications, hospitalization, operative time, and pain over the traditional technique. Sexuality approaches so-called "normal" sexuality.
