This study included 36 patients for whom we analyzed the demographic and clinical data relevant to age, sex, co-morbid factors, location of tumour, site of specimen extraction, hernia occurrence, surgical site infection, postoperative pain, length of hospital stay for patients underwent hand assisted anterior resection under general anesthesia, was performed using the four port method.

in categorical variables between groups were analyzed using the chi-squared test and Fisher‘s exact test, and quantitative variables and independent groups were compared with the Mann–Whitney test and the t test. Statistical significance was defined by P value.
The current study results suggest that hernia occurrence, surgical site infection, postoperative pain, length of hospital stay are less in specimen extraction through pfaneinnsteil incision than lower midline
