This study was designed to clarify the postoperative major complications of total pelvic exenteration for locally advanced colorectal cancer. Twenty-six patients (primary disease: 17, recurrent disease: 9) were retrospectively studied. Major complications developed in 30.8% (8 of 26); in 23.5% (4 of 17) for a primary disease and in 44.4% (4 of 9) for a recurrent disease. Only 2 patients (7.7%) died within 30 days after the operation; one patient died of hepatic failure and another of pelvic
sepsis

developed at a high rate of 11.5% (3 of 26). Ileo-ileal anastomotic leakage developed at a rate of 7.7% (2 of 26) and it commonly occurred following irradiation. The remaining one patient had gastrointestinal bleeding. These 6 patients surviving the operation were successfully managed conservatively. Conclusion was as follows: Total pelvic exenteration should be performed carefully and aggressively regardless of the development of postoperative complications.

Paralytic ileus is defined as an inhibition of propulsive intestinal motility.
Postoperative ileus
is the most common type, however, also during
sepsis
and critical illness paralytic ileus is a common finding. The pathogenesis of paralytic ileus is still debated. It is believed to result from the activation of inhibitory neural reflex pathways and activation of inflammatory processes. It is generally accepted that postoperative ileus results from the activation of an inhibitory neural reflex pathway. In our rat model we showed that different degrees of nociceptive stimulation activate different reflex pathways: laparatomy activates an adrenergic inhibitory reflex pathway, whereas manipulation results in additional activation of inhibitory NANC neurons releasing NO and VIP as neurotransmitters. We also demonstrated that blockade of the afferent limb of the reflex pathway by peripheral kappa-opioid agonists or by non-steroidal anti-inflammatory drugs ameliorated postoperative ileus. However, the use of prokinetics lead to disappointing results. In the murine septic model we demonstrated an important role for activation of inducible NO synthase in the endotoxin-induced delay in gastric emptying and small intestinal transit. We hypothesise that activation of the residential macrophages in the gut wall leads to the production of iNOS and other inflammatory mediators. These mediators will attract more inflammatory cells and influence smooth muscle contractility. Next, we provide evidence that production of iNOS results in the activation of guanylyl cyclase leading to the production of cGMP and smooth muscle relaxation. However, a parallel mechanism of action for NO via oxidative stress needs further investigation.

Postoperative ileus
(POI) is a complex phenomenon with important morbidity and mortality, well known in many surgical fields. POI occurs commonly after abdominal and pelvic surgery, especially in cancer patients. We report the case of a 63-year-old patient without known risk factors for POI, who underwent total hysterectomy with bilateral adnexectomy for ovarian tumor with suspicion of malignancy, invalidated by the extemporaneous pathology examination. The postoperative evolution is marked by reduced bowel movements, lack of intestinal transit for flatus and stool for 6 days. In cooperation with the general surgeon conservative treatment for POI was administered, without effect. The abdomen remained distended, with no nausea or vomiting. On the 6th postoperative day a wound dehiscence with incomplete evisceration occurred, after a CT scan of the abdomen and pelvic region was requested to make a differential diagnosis between an intestinal mass and other pathology involving the bowell. In conjunction with the General Surgery team the surgical reintervention was decided and performed. After the procedure, the patient successfully regained transit, with flatus and stool emission, but another 2 complications occurred, which were successfully treated:
sepsis
and deep vein thrombosis. Understanding the pathophysiology could help to prevent, diagnose, and implement protocols in order to avoid POI and its complications, to reduce hospital stay and cost burden.
