There is no standard treatment in patients with high risk metachronous peritoneal carcinomatosis (PC) in colonic cancer, as perforated tumour or synchronous ovarian metastasis. Icodextrin 4% (ICDX), presently used to prevent postoperative abdominal adhesions, could inhibit the coactivation of the tumour cells and the microenvironment cells, associated with the development of PC. The aim of this study was to inhibit the formation of the PC in a murine model mimicking surgical situation using ICDX and intraperitoneal (IP) prophylactic chemotherapy...

INTRODUCTION: During Robotic-Assisted Radical Prostatectomy (RARP), the prostate may be approached extraperiteoneally (eRARP) or transperitoneally (tRARP). The former avoids the abdominal cavity which might be of benefit in patients who have had prior abdominal or pelvic surgery (PAPS). Our objective was to compare the outcomes of patients with PAPS undergoing either technique. METHODS: A retrospective review of patients treated with RARP from July 1, 2003-Dec. 31, 2014 with a minimum follow-up of 3 months was undertaken...

BACKGROUND: Gossypiboma is a serious and potentially dangerous medico-legal problem. CASE PRESENTATION: We present a case of lower abdominal gossypiboma that presented as an abdominal cystic mass mimicking ovarian teratoma. The mass and the adhesive intestine loop were en blocly resected. The cut section confirmed gossypiboma diagnosis. CONCLUSIONS: The present experience and related literature results indicate that gossypiboma should always be kept in mind for the differential diagnosis of cystic soft-tissue mass detected in patients with a prior operation history despite its rarity and diagnosis difficulty...

BACKGROUND/GOAL: Intra-abdominal adhesions are probably underdiagnosed cause for chronic abdominal pain. Our aim was to evaluate late (>10 y) effect of laparoscopic adhesiolysis on chronic abdominal pain. STUDY: This was a nonrandomized follow-up study of 68 patients (9 males, 59 females) who suffered chronic abdominal pain. The index operation (laparoscopy and adhesiolysis; n=72 patients) was performed during 1997 to 2001. A quality-of-life questionnaire was asked after the mean follow-up time of 15 years...

We present a rare case of indirect vesicovaginal fistula (VVF) in a patient with small capacity bladder. The fistula was between abdominal pseudocyst (APC) arising from bladder and vagina - and hence, an indirect VVF. A 35-year-old female had a history of emergency obstetric hysterectomy with iatrogenic bladder injury. Postoperatively, the patient developed VVF and large APC. Patient's micturating cystourethrogram was suggestive of small capacity bladder with bilateral Grade IV vesicoureteral reflux with a well-defined APC arising from superior surface of bladder to L4-L5 lumbar vertebrae...

BACKGROUND: The clinical prognosis of gastric cancer with peritoneal dissemination is poor because of its chemoresistance and rich fibrosis. While several gastric cancer cell lines have been used to establish models of peritoneal dissemination by intraperitoneal injection, most peritoneal tumors that form adopt a medullary pattern in microscopic appearance. This histological finding for the model differs from that in the clinical situation. This study was performed to demonstrate the contribution of human peritoneal mesothelial cells (HPMCs) to fibrotic tumor formation and to establish a new xenograft model with high potential for peritoneal dissemination with organ invasion and extensive fibrosis...

BACKGROUND: Large sheet-type surgical materials (e.g., absorbable hemostat, adhesion barrier membranes, and flat surgical mesh) are difficult to introduce into a corporeal cavity using a 5-mm trocar; however, laparoscopic surgeries that use mainly 5-mm trocars are increasing. Furthermore, it is necessary not only to introduce but also to secure the applied surgical material and expand it from the original surgical site. To address these challenges, we developed a novel procedure for introducing such surgical materials into a corporeal cavity using a 5-mm trocar and a self-expanding origami structure, called the "chevron pleats procedure (CPP)"...

BACKGROUND: Normal saline gained wide popularity in abdominal surgery as a basic compound used in intraoperative drainage of the peritoneal cavity. However, recent studies have revealed that saline solution is not quite biocompatible with the intraperitoneal enviroment and may promote peritoneal adhesions. OBJECTIVES: The aim of the study was to evaluate the function and viability of human mesothelial cells cultured in vitro in 0.9% NaCl solution from intraperitoneal lavage carried out during laparoscopic cholecytectomies...

BACKGROUND AND OBJECTIVES: Small-bowel obstruction (SBO) is a common surgical emergency that occurs in 9% of patients after abdominal surgery. Up to 73% are caused by peritoneal adhesions. The primary purpose of this study was to compare the rate of SBOs between patients who underwent laparoscopic (LPS) and those who had open (OPS) colorectal surgery. The secondary reasons were to evaluate the rate of adhesive SBO in a cohort of patients who underwent a range of colorectal resections and to assess risk factors for the development of SBO...

Background: A 32-year-old woman with tubal factor infertility due to bilateral laparoscopic salpingectomy conceived twins with in vitro fertilization (IVF). She developed moderate ovarian hyperstimulation syndrome which was treated with anticoagulant therapy. The subsequent course of the twin pregnancy was normal until the 17th week of gestation when she presented to hospital because of a sharp pain in the right lower abdomen which ceased after admission. Case: Except for a single incident of vomiting, patient had no other subjective symptoms...

BACKGROUND: Adhesion grades and adhesion breaking strength are widely used to assess severity of intraperitoneal adhesion in animal models. However, the results of adhesion grades have the large deviations due to vary personal experience. Adhesion breaking strength ignores the details of adhesion. This study introduced work of separation, the energy consumption during breakage of adhesion, to better evaluate intraperitoneal adhesion. METHODS: The intraperitoneal adhesion was induced by traumas created at rat cecum and adjacent abdominal wall...

BACKGROUND: Monocyte chemoattractant protein-1 (MCP-1)-mediated inflammatory mechanisms have been shown to play a crucial role in atrial fibrosis induced by pressure overload. In the present study, we investigated whether left atrial endothelial cells would quickly respond structurally and functionally to pressure overload to trigger atrial fibrosis and fibrillation. METHODS AND RESULTS: Six-week-old male Sprague-Dawley rats underwent suprarenal abdominal aortic constriction (AAC) or a sham operation...

Sepsis continues to result in high morbidity and mortality. General anesthesia is often administered to septic patients, but the impacts of general anesthesia on host defense are not well understood. General anesthesia can be given by volatile and intravenous anesthetics. Our previous in vitro study showed that volatile anesthetic isoflurane directly inhibits leukocyte function-associated antigen-1 (LFA-1) and macrophage-1 antigen (Mac-1), critical adhesion molecules on leukocytes. Thus, the role of isoflurane exposure on in vivo LFA-1 and Mac-1 function was examined using polymicrobial abdominal sepsis model in mice...

Splenic injury is an extremely rare, yet serious, complication related to colonoscopy. So far, less than 80 cases have been reported worldwide since 1970. With the increasing use of colonoscopy, endoscopists, surgeons and radiologists are more likely to encounter this unusual complication. Increased splenocolic adhesions, splenomegaly or underlying splenic disease might, inter alia, constitute a predisposing factor. However, it might also occur in patients without significant adhesions or underlying splenic pathology...

Background: Adhesions to intraperitoneally implanted meshes (IPOM) are a common problem following hernia surgery and may cause severe complications. Recently, we showed that missing peritoneal coverage of the intestine is a decisive factor for adhesion formation and 4DryField(®) PH (4DF) gel significantly prevents intestine-to-mesh adhesions even with use of uncoated Ultrapro(®) polypropylene mesh (UPM). The present study investigates adhesion prevention capability of coated Parietex(®) mesh (PTM) and Proceed(®) mesh (PCM) in comparison to 4DF treated UPM...

Mingxing Sui, Yanling Pei, Dong Li, Qiaori Li, Peining Zhu, Tianmin Xu, Manhua Cui
Cervical minimal deviation adenocarcinoma (MDA) is a rare variant of cervical adenocarcinoma that is difficult to diagnose due to the deep location, endogenous growth pattern, deceptively benign appearance of tumor cells, and lack of connection to human papillomavirus (HPV). Cytological evaluation and biopsies offer suboptimal detection and transvaginal sonography or Magnetic Resonance Imaging (MRI) only reveal multiple lesions that mimic multiple benign nabothian cysts. Besides, standard screening, diagnostic tools, and treatments are not established...
