Endometriosis is a common, chronic, benign, estrogen dependent gynecological disorder associated to pelvic pain and infertility. Its main characteristic is the presence of endometrial tissue outside the uterus. The prevalence of pelvic endometriosis ranges between 6% and 10% women during their reproductive years. Clinical symptoms of pelvic endometriosis are pelvic pain, dysmenorrhea, dispareunia and infertility. Distal ileum endometriosis is an uncommon cause of intestinal obstruction with a frequency of 7% to 23% of all cases with intestinal involvement. We report two patients, 30 and 34 years old, with terminal ileum endometriosis and intestinal obstruction that required surgery and intestinal resection. Both patients are well one year after the operation.

Post-operative peritoneal adhesions can cause pelvic pain, infertility, and potentially lethal bowel obstruction. We have designed and synthesized injectable hydrogels that are formed by mixing hydrazide-modified hyaluronic acid (HA) with aldehyde-modified versions of cellulose derivatives such as carboxymethylcellulose (CMC), hydroxypropylmethylcellulose (HPMC), and methylcellulose (MC). Gelation of these hydrogels occurred in less than 1 min, and had higher shear moduli than that of HA-HA gel (HAX). Hydrogels degraded in the presence of hyaluronidase in vitro, with HA-MC and HA-HPMC degrading more slowly than HAX and HA-CMC. The aldehyde-modified cellulose derivatives showed dose-dependent mild-to-moderate cytotoxicity to mesothelial cells and macrophages in vitro, but all were biocompatible in the murine peritoneum, causing no adhesions for 3 weeks. All the cellulose-derived gels showed efficacy in reducing the area of adhesion formation in a rabbit sidewall defect-bowel abrasion model.

Ovarian remnant syndrome is defined as residual ovarian tissue non intentionally left in place by the surgeon during a bilateral salpingo-oophorectomy. Patients present various symptoms usually including chronic pelvic pain, pelvic mass, bowel obstruction, hydronephrosis due to ureteral compression. We report a case of adenocarcinoma arising in such an ovarian remnant revealed by vaginal bleeding 5 years after total abdominal hysterectomy and bilateral oophorectomy for uterine fibroids. It was regarded as stage IIIc according to the FIGO classification because of common iliac lymph node involvement while there was no ascitis, no peritoneal nor omental implant but a unilateral hydronephrosis induced by extrinsec ureteral obstruction. Complete cytoreductive surgery was achieved including partial bladder and lower ureteral resection with colpectomy, omentectomy, pelvic and para-aortic lymphadenectomy. Paclitaxel-Platinum combination chemotherapy was given for nine cycles.

Postoperative peritoneal adhesions cause pelvic pain, infertility, and potentially lethal bowel obstruction. We have designed and synthesized an injectable hydrogel composed of cross-linkable modified hyaluronic acids (HAs) conjugated to dexamethasone (HAX-DEX), and investigated its anti-inflammatory function. HAX-DEX formed a hydrogel in <1min by cross-linking reactions between aldehyde groups and hydrazide groups. The hydrogel degraded in media over 5 days, releasing dexamethasone slowly over that time, reducing TNF-alpha and IL-6 production from lipopolysaccharide-stimulated primary mouse macrophages in vitro. HAX-DEX was biocompatible on subcutaneous injection, and caused less inflammation than unmodified cross-linked HA.

Adhesions resulting from gynaecological endoscopic procedures are a major clinical, social and economic concern, as they may result in pelvic pain, infertility, bowel obstruction and additional surgery to resolve such adhesion-related complications. Although the minimally invasive endoscopic approach has been shown to be less adhesiogenic than traditional surgery, at least with regard to selected procedures, it does not totally eliminate the problem. Consequently, many attempts have been made to further reduce adhesion formation and reformation following endoscopic procedures, and a wide variety of strategies, including surgical techniques, pharmacological agents and mechanical barriers have been advocated to address this issue. The present review clearly indicates that there is no single modality proven to be unequivocally effective in preventing post-operative adhesion formation either for laparoscopic or for hysteroscopic surgery. Furthermore, the available adhesion-reducing substances are rather expensive. Since excellent surgical technique alone seems insufficient, further research is needed on an adjunctive therapy for the prevention and/or reduction of adhesion formation following gynaecological endoscopic procedures.

Intra-abdominal adhesions are normally found after most surgical procedures. Many of the adhesions are asymptomatic, but in about 5% they will lead to readmission due to adhesion-related disorders, such as small bowel obstruction, pelvic pain and infertility. This review discusses possible ways to prevent abdominal adhesions and provides an update as comes to where we stand today in research regarding experimental and clinical use of various antiadhesive agents.

Consequences and complications of postsurgical intra-abdominal adhesion formation not including small bowel obstruction and secondary infertility are substantial but are under-exposed in the literature. Inadvertent enterotomy during reopening of the abdomen or subsequent adhesion dissection is a feared complication of surgery after previous laparotomy. The incidence can be as high as 20% in open surgery and between 1% and 100% in laparoscopy depending on the underlying disease. Delayed postoperative detection of enterotomy is a particular feature of laparoscopy associated with significant morbidity and mortality. Adhesions to the ventral abdominal wall are responsible for the majority of trocar injuries. Both trocar injuries and inadvertent enterotomies result in conversion from laparoscopy to laparotomy in almost 100% of cases. There is a paucity of data on other organ injury, such as liver laceration or bladder perforation. Dissecting adhesions before executing the planned operation takes on average 20 min, being one-fifth of the total operating time in patients having had previous open colorectal surgery. There is some evidence that postoperative morbidity and mortality of patients who need adhesiolysis is higher than that of patients with a virgin abdomen. The necessity to dissect adhesions is associated with increased hospital stay. Postsurgical adhesions are considered a main reason for conversion from laparoscopy to laparotomy in many types of procedures including laparoscopic colonic resection. Adhesion formation is part of the innate peritoneal defence mechanism in peritonitis. Abscess formation and bleeding, organ injury and fistula formation at 'on demand' relaparotomies are well-known complications after surgery for intra-abdominal sepsis associated with fibrinous adhesions. The clinical magnitude hereof is poorly researched. Postsurgical adhesions may cause pain as evidenced by pain mapping clinical experiments. Filmy adhesions between movable organs and the peritoneum appear to be worse in terms of generating pain. The high caseload of gynaecological and some colorectal practices suggest an enormous impact of adhesion-related chronic abdominal and pelvic pain on patient's wellbeing and socio-economic costs. The significant risk of inadvertent enterotomy, conversion to laparotomy and trocar injury, and the associated postoperative morbidity and mortality and increased length of hospital stay warrant routine informed consent of adhesiolysis related complications in patients scheduled for abdominal or pelvic reoperation.

Mounting evidence highlights that adhesions are now the most frequent complication of abdominopelvic surgery, yet many surgeons are still not aware of the extent of the problem and its serious consequences. While many patients go through life without apparent problems, adhesions are the major cause of small bowel obstruction and a leading cause of infertility and chronic pelvic pain in women. Moreover, adhesions complicate future abdominal surgery with important associated morbidity and expense and a considerable risk of mortality. Studies have shown that despite advances in surgical techniques in recent years, the burden of adhesion-related complications has not changed. Adhesiolysis remains the main treatment even though adhesions reform in most patients. Recent developments in adhesion-reduction strategies and new anti-adhesion agents do, however, offer a realistic possibility of reducing the risk of adhesions forming and potentially improving the clinical outcomes for patients and reducing the associated onward burden to healthcare systems. This paper provides a synopsis of the impact and extent of the problem of adhesions with reference to the wider literature and also consideration of the key note papers presented in this special supplement to Colorectal Disease. It considers the evidence of the risk of adhesions in colorectal surgery and the opportunities and strategies for improvement. The paper acts as a 'call for action' to colorectal surgeons to make prevention of adhesions more of a priority and importantly to inform patients of the risks associated with adhesion-related complications during the consent process.

Tissue trauma in the peritoneal and pelvic cavities following surgery or bacterial infection results in adhesions that are a debilitating cause of intestinal obstruction, chronic pelvic pain, and infertility in women. We recently demonstrated that CD4(+) alphabeta T cells are essential for development of this process. Using a murine model of experimental adhesion formation, we now demonstrate that adhesion formation is characterized by the selective recruitment of Tim-3(+), CCR5(+), CXCR3(+), IFN-gamma(+) cells, indicating the presence of a Th1 phenotype. We further demonstrate that adhesion formation is critically dependent on the function of Th1 cells because mice genetically deficient for IFN-gamma, T-bet, or treated with Abs to the Th1-selective chemoattractant IL-16 show significantly less adhesion formation than wild-type mice. In addition, disrupting the interaction of the Th1-specific regulatory molecule Tim-3, with its ligand, significantly exacerbates adhesion formation. This enhanced response is associated with increases in the level of neutrophil-attracting chemokines KC and MIP-2, known to play a role in adhesiogenesis. These data demonstrate that the CD4(+) T cells orchestrating adhesion formation are of the Th1 phenotype and delineate the central role of T-bet, Tim-3, IFN-gamma, and IL-16 in mediating this pathogenic tissue response.

Abdominal and pelvic adhesions are a frequent occurrence and are responsible for significant morbidity resulting in abdominal and pelvic pain, infertility, and small bowel obstruction. The process of adhesion development begins when damage to peritoneal surfaces from any source (operative trauma, infection, foreign bodies, desiccation, irradiation, allergic reaction, or chemical injury) induces a series of biochemical/molecular biologic cascades involving different elements. These elements include peritoneal fluid, neutrophils, leukocytes, macrophages, cytokines, mesothelial cells, and tissue and coagulation factors, which teleologically have the intention of peritoneal repair; however, these processes also result in adhesion development. Major pathways that play significant roles in the healing process of peritoneal damage leading to adhesion development are the fibrinolytic system, extracellular matrix deposition, growth factor and cytokines, cell adhesion molecules, angiogenesis, apoptosis and proliferation, and remesothelialization. Greater understanding of the regulation and interaction of these processes provides the potential for reduction of postoperative adhesion development.
