RESUMO
BACKGROUND/OBJECTIVE: In the late's 90' a new surgical treatment, the stapled trans-anal rectal resection (STARR) was born to treat obstructed defecation syndrome (ODS). In this study we retrospectively analyze a series of 450 cases that underwent STARR in 10 years. METHODS: Between January 2001 to December 2011, 450 patients, diagnosed with ODS syndrome caused by rectocele or intussusception, underwent to STARR procedure. The presence of rectocele and/or intussusception was verified by dynamic defecography. The preoperative evaluation was completed with anorectal manometry and colonoscopy. Follow-up visits were scheduled 1 week, 1 month, 3 months, 1 years, 3 years and 5 years after surgery. RESULTS: Mean operative time was 30,2 min. In 408 cases (90.7%) hospital discharge occurred 24 hours after surgery. Among postoperative complications urinary retention was observed in 35 patients (7.8%). Five (1.1%) patients presented an early rectal bleeding and 8 (1.8%) patients presented a late bleeding. In 5 (1.1%) patients a stable pelvic hematoma was found. Six (1.3%) patients presented pelvic sepsis due to subperitoneal perforation. An asymptomatic partial dehiscence of stapler row occurred in 19 patients (4.2%).125 patients (27.8%) reported defecation urgency that completely vanished at 3 months follow-up in 83 patients (66,4%) and in further 42 patients (33,6%) at 6-months. The average preoperative ODS score was 14.1; 3.1 at one year; 4.3 at 3 years and 6.4 after five years. CONCLUSIONS: In expert hands, with right indications, STARR procedure is safe with good results in terms of improvement of the ODS score.

The aim of this article is to assess whether measures of abdominal fat distribution, visceral density, and antropometric parameters obtained from computed tomography (CT) may predict postoperative pancreatic fistula (POPF) occurrence.We analyzed 117 patients who underwent pancreatoduodenectomy (PD) and had a preoperative CT scan as staging in our center. CT images were processed to obtain measures of total fat volume (TFV), visceral fat volume (VFV), density of spleen, and pancreas, and diameter of pancreatic duct. The predictive ability of each parameter was investigated by receiver-operating characteristic (ROC) curves methodology and assessing optimal cutoff thresholds. A stepwise selection method was used to determine the best predictive model.Clinically relevant (grades B and C) POPF occurred in 24 patients (20.5%). Areas under ROC-curves showed that none of the parameters was per se significantly predictive. The multivariate analysis revealed that a VFV >2334âcm, TFV >4408âcm, pancreas/spleen density ratio <0.707, and pancreatic duct diameter <5âmm were predictive of POPF. The risk of POPF progressively increased with the number of factors involved and age.It is possible to deduce objective information on the risk of POPF from a simple and routine preoperative radiologic workup.
