Klek, Stanislaw; Kulig, Jan; Sierzega, Marek; Szczepanek, Kinga; Szybiński, Piotr; Scislo, Lucyna; Walewska, Elzbieta; Kubisz, Aldona; Szczepanik, Antoni M
BACKGROUND & AIM/OBJECTIVE:The immunomodulating enteral diets are intended to reduce the incidence of postoperative complications in surgical patients. The aim of the study was to assess the clinical effect of such nutrition. MATERIALS AND METHODS/METHODS:Between June 2004 and September 2007 196 well-nourished patients undergoing resection for pancreatic and gastric cancer were randomized in double-blind manner to receive postoperative enteral nutrition with immunostimulating diet (IMEN group) or standard oligopeptic diet (SEN group). Outcome measures were: number and type of complications, length of hospital stay, mortality, treatment tolerance, liver and kidney function. RESULTS:One hundred and ninety six patients were initially enrolled, finally 183 patients (91 SEN, 92 IMEN group; 69 F, 114 M, median age 61.2) were analyzed. Median postoperative hospital stay was 12.4 days (SD 5.9) in SEN and 12.9 days (SD 8.0) in IMEN group (p=0.42). Complications were observed in 21 patients (23.1%) in SEN and 23 (25.2%) in IMEN group (p>0.05). Four (4.4%) patients in SEN group and 4 (4.4%) in IMEN had surgical complications (p>0.05). There were no differences in liver and kidney function, visceral protein turnover and treatment tolerance. CONCLUSION/CONCLUSIONS:Results of our study showed no benefit of immunomodulating enteral nutrition over standard enteral nutrition in patients after major gastrointestinal surgery. The Trial was registered in Clinical Trials Database--number: NCT00576940.

[The value of endorectal ultrasound (ERUS) in the assessment of the clinical severity of ulcerative colitis]
Kibil, Wojciech; Kłek, Stanisław; Gurda-Duda, Anna; Kopciński, Paweł; Kulig, Jan
AIM/OBJECTIVE:Endorectal ultrasonography (ERUS) represents a relatively new diagnostic tool enabling easy and precise assessment of rectal wall lesions, used mostly in diagnosing of the carcinoma of the rectum. It seems to be a valuable examination in the evaluation of the severity of ulcerative colitis. METHODS:56 patients (23 F, 33 M; mean age 51.4, range 17-72) with histopathologically confirmed ulcerative colitis, operated at 1st Departament of General and GI Surgery in Cracow, were enrolled to the study. In all patients endorectal ultrasonography was performed to assess the severity of the disease. The diagnostic accuracy, sensitivity and specificity, PPV and NPV of ERUS were analyzed basing on intraoperative surgical assessment and postoperative histopathological examination. RESULTS:The sensitivity of ERUS reached 85.7 per cent, specificity was high - 97.3 per cent PPV - 88.9 per cent, NPV - 92.4 per cent and overall accuracy 95 per cent. CONCLUSIONS:The assessment of the severity of ulcerative colitis using endorectal ultrasonography corresponds with clinical severity of the disease. ERUS is a valuable, relatively cost-effective diagnostic tool of high overall accuracy, which may be helpful in clinical evaluation and monitoring of ulcerative colitis.

The role and value of endorectal ultrasonography in diagnosing T1 rectal tumors
Kulig, Jan; Richter, Piotr; Gurda-Duda, Anna; Gach, Tomasz; Klek, Stanislaw
Rectal carcinoma in 50% to 60% of cases is localized in the rectum and, if diagnosed early can be locally excised. The authors evaluated the diagnostic accuracy of the preoperative endorectal ultrasonography (ERUS) in the staging of rectal tumors and the usefulness of the method to assess patients' suitability for local excision. In the retrospective analysis, we analyzed 29 patients with rectal cancer. The depth of invasion into the rectal wall was assessed by ERUS and all patients were qualified for tumor excision with transanal endoscopic microsurgery (TEM). We analyzed overall accuracy of ERUS and the effectiveness of treatment. In the analyzed group, diagnostic accuracy of ERUS in assessing T1 carcinomas was 89.2%, sensitivity 92.3% and specificity 50%. Local excision with TEM was deemed to be curative in 86.2% patients with rectal tumors detected by ERUS. ERUS is an accurate method of preoperative assessment of T1 and T2 carcinomas and its diagnostic accuracy is sufficient to qualify patients for anal-saving operations.

Outcome of gastric cancer surgery in elderly patients
Kolodziejczyk, P; Kulig, J; Popiela, T; Sierzega, M; Jedrys, J; Czupryna, A; Kubisz, A; Szczepanik, A; Klek, Stanislaw
BACKGROUND/AIMS/OBJECTIVE:The aim of the study was to review cases of gastric cancers in elderly adults (70 years of age and older), and compare demographic, clinical, pathologic features and outcomes of surgical treatment with younger patients (below 70 years of age). METHODOLOGY/METHODS:The analysis included 3431 patients treated for gastric cancer between 1977 and 1998 at eight university surgical centers cooperating for the Polish Gastric Cancer Study Group (PGCSG). Patients were analyzed retrospectively according to data obtained from standardized forms and divided into two groups: group I--patients 70 years of age and over, group II--younger patients. RESULTS:There were no significant differences between these two groups in clinical symptoms at the time of diagnosis and tumor advancement. The incidence of the intestinal type according to Lauren (55.9% vs. 43.9%;p<0.05) and distally-located cancers (40.8% vs. 31.3%; p<0.05) was higher in group I. Total gastrectomies and extended lymph node dissection were performed more often in younger patients. There were no significant differences in postoperative complications between both groups, except the higher incidence of abdominal abscesses in the younger group. The overall 5-year survival was 24% and 35% for group I and II, respectively (p<0.05), and increased to 35% and 53% after radical resections, respectively. However, there were no statistically significant differences in stage-specific survival between both groups. CONCLUSIONS:Surgical resection is the method of choice in the treatment of gastric cancer. Age of the patients is not a contraindication to surgical treatment of gastric cancer.
