Article Synopsis
- The study investigates long-term outcomes for patients who experienced a first episode of acute uncomplicated diverticulitis (UD) in the left colon, finding that almost 50% had at least one recurrence over a decade of follow-up.
- Out of 105 patients, nearly 20% eventually required elective surgery, primarily due to multiple recurrences, with male patients being more likely to need surgery.
- The research indicates that common classification systems do not effectively predict recurrences, though a specific stage (CDD 1a) was linked to lower chances of requiring surgery.
Direct toll-like receptor triggering in colorectal cancer-associated stromal cells elicits immunostimulatory properties leading to enhanced immune cell recruitment.

Background: Postoperative pain represents an important issue in traditional hemorrhoidectomy. Optimal pain control is mandatory, especially in a surgical day care setting.
Objective: The aim of this study was to investigate the use of pudendal nerve block in patients undergoing hemorrhoidectomy.
Lumbo-sacral chordoma is a rare, slow-growing tumor, arising from embryonic nothocordal remnants. Wide en bloc excision with clear margins remains mandatory to achieve satisfactory recurrence rates and disease-free survival. No chemotherapy has been demonstrated to be effective and radiotherapy is only marginally effective.

The body mass index (BMI) does not always correlate to intra-abdominal fat distribution. Our hypothesis was that simple anthropometric measures that reflect VO, could predict technical difficulty in laparoscopic colorectal surgery, as reflected by the operative time, more accurately than the BMI.

Objective: We hypothesized that pursestring near-complete closure of the stoma site would lead to fewer surgical site infections compared with conventional primary closure.
Purpose: A sacral chordoma is a rare, slow-growing, primary bone tumor, arising from embryonic notochordal remnants. Radical surgery is the only hope for cure. The aim of our present study is to analyse our experience with the challenging treatment of this rare tumor, to review current treatment modalities and to assess the outcome based on R status.

The aim of this study was to analyze risk factors for surgical site infection (SSI) in this context.
Methods: All consecutive patients undergoing excision and primary closure for PD from January 2002 through October 2008 were retrospectively assessed.
Background: Stoma closure has been associated with a high rate of surgical site infection (SSI) and the ideal stoma-site skin closure technique is still debated. The aim of this study was to compare the rate of SSI following primary skin closure (PC) versus a skin-approximating, subcuticular purse-string closure (APS).
Methods: All consecutive patients undergoing stoma closure between 2002 and 2007 by two surgeons at a single tertiary-care institution were retrospectively assessed.
Purpose: Transanal endoscopic microsurgery provides a minimally invasive alternative to radical surgery for excision of benign and malignant rectal tumors. The purpose of this study was to review our experience with transanal endoscopic microsurgery to clarify its role in the treatment of different types of rectal pathology.
Methods: A prospective database documented all patients undergoing transanal endoscopic microsurgery from October 1996 through June 2008.
Derived-band click-evoked auditory brainstem responses (ABRs) were obtained for normal-hearing (NH) and sensorineurally hearing-impaired (HI) listeners. The latencies extracted from these responses, as a function of derived-band center frequency and click level, served as objective estimates of cochlear response times. For the same listeners, auditory-filter bandwidths at 2 kHz were estimated using a behavioral notched-noise masking paradigm.
View Article and Find Full Text PDFObjective: To compare transanal endoscopic microsurgery (TEMS) with conventional transanal excision (TAE) in terms of the quality of resection, local recurrence, and survival rates in patients with stage I rectal cancer.
Background: Although TEMS is often considered a superior surgical technique to TAE, it is poorly suited for excising tumors in the lower third of the rectum. Such tumors may confer a worse prognosis.
Purpose: In this study we compared the outcomes of patients with complex cryptoglandular fistulas treated by endorectal advancement flap or anal fistula plug.
Methods: We performed a retrospective analysis of patients with transsphincteric anal fistulas treated by endorectal advancement flap or anal fistula plug from January 1996 through April 2007. Patients with noncryptoglandular fistulas or insufficient follow-up were excluded.
Purpose: Anal fistulas that involve a significant amount of sphincter may be difficult to treat without compromising continence function. In this study, we evaluated our experience with the Surgisis anal fistula plug, which was recently reported to be successful in >80 percent of patients with complex fistulas.
Methods: We retrospectively collected patient and fistula characteristics, procedure details, and follow-up information for all patients treated with the anal fistula plug at our institution from January 2006 through April 2007.
