Abstract:
Introduction: The elective method of surgical intervention with curative intent in colorectal neoplasm is a radical surgery with a classic approach followed by different types of anastomosis. These types
of surgical interventions are accompanied by a series of postoperative complications with impact on the
period of recovery of the patient; these complications can be prevented by knowing the precipitating factors that favor their occurrence.
Materials and methods: We performed a prospective study in which 750 patients with colorectal
neoplasm resection were selected, 284 females and 465 males. The patients suffered surgical interventions
with the classic approach and received segmental or total colorectal resections at the 3rd Surgical Clinic
(Cluj-Napoca, Romania) between 01.01.2009 -01.12.2010. The study is based on postoperative complications and the following criteria were selected: bleeding, suppurated wound, anastomotic fistula, systemic
complications (evisceration, abdominal abscess, urine retention, and thrombo-embolism, respiratory or
cardiac complications) and fecal incontinence. The observed data was collected from patient observation
files and standard sheets specially designed for this study.
Results: We observed an increased prevalence of postoperative wound suppurations in patients that
were living in urban areas with a frequency of 47.22% male patients with a frequency of 43.83%. Suppurative wound surgery is validated significantly in frequency among patients who had increased biological parameters that were evaluated preoperatively: 54.08% for urea, 54% for creatinine, 46.08% for
TGO, 50% for TGP, 50% for platelet count, 51,4% for total bilirubin, 50.86% for amylases, 38.15% for
blood glucose, 49.09% for hemoglobin, 52.63% for total protein, 90.9% for CEA, 54.45% for patients who
received preoperative transfusions, 55.23% for patients that received preoperative anticoagulation treatment, 53.39% for patients that did not received intraoperative transfusions and 47.19% for those who
claimed chronic alcoholism.
In patients whose neoplastic process underwent surgical intervention in one surgical step and who
underwent direct anastomosis the most common postoperative complication of suppurative wound had
relevant percentage of 53.84%. The study found a relative dispersion taking in account the majority of
elements for suppurative wound complications who weren’t significantly correlated with the location of
the incision in segmental resection for different levels on the colorectal framework, for the ascending
colon we got a percentage of 41.17%, 80% for the transverse colon, 60% for the descending colon, 60%
for the sigmoid colon, 48.38% for the superior and medium thirds of the rectum and 35% for the inferior
third of the rectum. Also the analyzed data are showing a relevant percent of 51.47 for the patients whose
anastomosis was done in a single layer.
Conclusions: The most common postoperative complication is suppurative wound and it is determined by the living area of the patient, sex of the patient and requires a faithful correction of the biological parameters with tendency for homeostasis. The distribution of the complications regarding the level
for the segmental resection is statistically insignificant because of the dispersion rates of the occurrence
of postoperative suppurative wound for different locations for segmental resection along the colorectal
frame. The dates are also suggesting that the surgery steps in which the patients with neoplastic processes
are operated is significantly related to postoperative events.
