Chronic pelvic pain is a hidden issue which needs to involve many different usually uncoordinated specialists. For this reason there is a risk that treatments, in the absence of well-defined pathways, common goals, and terminology, may be poorly effective. The aim of the present paper is to summarize the evidence on anorectal pelvic pain, offering useful evidence-based practice parameters for colorectal surgeons' daily activity. Analysis of chronic anorectal and pelvic pain syndromes, the diagnostic and clinical optimal needs for evaluation, and the innumerable low evidence treatments and therapeutic options currently available suggests that a multimodal individualized management of pain may be the most promising approach. The limited availability of dedicated centers still negatively affects the applicability of these principles., (© 2024. Springer Nature Switzerland AG.)

Staging of pancreatic cancer still represents a challenge for surgeons involved in this field. Diagnostic methods of radiological imaging used routinely (CT, NMR, angiography) may understage this neoplasm. In fact, the presence of peritoneal or subglissonian hepatic micrometastases (< 2 cm) is a frequent surprise at laparotomy and forces the surgeon to use a palliative procedure. Actually this policy has not to be followed because the possibility to perform non-surgical palliation of jaundice or pain respectively by percutaneous radiological stent insertion and celiac alcoholization. In this viewpoint, preoperative staging has acquired an important role for a correct treatment, be it surgical or medical. Laparoscopy allows it to overcome the understaging produced by the more common diagnostic means, with the possibility to view directly the celomatic space and the surface of the abdominal viscera; moreover, during this procedure it is possible to perform a peritoneal washing to obtain other information about the cancer stage. In our experience, 56 patients were judged as resectable by radiologic methods; 31 were excluded from surgery by laparoscopy; 10 of the remaining 25 cases were submitted to radical resection. The operative resectability rate resulted in 40%, against 18% in cases where we submitted to surgery all the patients. Seven patients underwent peritoneal washing, always with a negative result; all were submitted to surgery and radically resected. In our opinion, laparoscopy and peritoneal washing represent useful tools in the staging of patients affected by pancreatic cancer.

To analyze the implication of retroperitoneal perineural lymphatic infiltration (rpli) for the survival of patients affected by exocrine pancreatic cancer, we considered 17 cases which underwent radical resection at our Institute from 1980 to 1993. Histology of specimens showed an rpli in 15 cases, without any correlation between this anatomopathologic aspect and the neoplasm size or the presence of lymph node metastases. The 2 patients without rpli are both alive and have been free from disease during a follow-up period of more than 5 years. In the group of 15 patients with positive rpli, 3 (21.4%) have remained free from disease (2 alive and 1 dead for other reason). Eleven remained with disease (1 is alive and 10 have died). One died in the postoperative period and could not be included in the evaluation. These observations have led the surgeon to consider the necessity, during resection, of an accurate dissection not only of the regional lymph nodes but also of the retropancreatic tissue and the neural structures present in this area. This approach may lead to a more correct staging of the neoplasia, a better radical surgery and perhaps a longer survival. Moreover it may represent an important marker for an adjuvant protocol of chemotherapy and/or radiotherapy.

The staging of pancreatic cancer still represents a challenge for surgeons involved in this field; radiological diagnostic methods used routinely (CT, NMR, angiography) may under-estimate this neoplasm; in fact, the presence of peritoneal or subglissonian hepatic micrometastasis (< 2 cm) is a frequent surprise at laparotomy and force the surgeon to undertake a palliative procedure. This policy need not be followed because it is possible to perform non-surgical palliation of jaundice or pain respectively by percutaneous radiological stent insertion and coeliac alcoholisation. Pre-operative staging thus acquires an important role in the correct treatment, surgical or medical. Laparoscopy allows us to overcome the understaging of the more common diagnostic methods and view directly the coelomatic space and the surface of the abdominal viscera; moreover during this procedure it is possible to perform a peritoneal wash to obtain other information on the cancer stage. We judged 56 patients by radiological diagnosis; 31 were excluded from surgery by laparoscopy; 10 of the other 25 cases were submitted to radical resection. The resectability operative rate was 40%, compared with 18% if we had submitted patients to surgery. Several patients underwent peritoneal wash, always with negative results; all were submitted to surgery and radically resected. In our opinion, laparoscopy and peritoneal wash represent useful tools in the staging of patients affected with pancreatic cancer.
