Background: The management of complicated appendicitis is inconclusive. Guidelines have not been established for the use of personalized antibiotic treatment.

Objectives: To investigate specific risk factors to consider during the initial first-choice antibiotic therapy in children with complicated appendicitis.

Methods: This study included all pediatric patients younger than 18 years of age who underwent a laparoscopic appendectomy during 2012–2022 at a single tertiary medical center.

Results: In total, 300 pediatric patients underwent laparoscopic appendectomy due to complicated appendicitis. The patients were treated with ceftriaxone + metronidazole (CM). For 57 (19%) patients, the empirical treatment was changed to tazobactam/piperacillin (TP) due to resistant bacteria or clinical deterioration. The presence of generalized peritonitis during surgery and C-reactive protein (CRP) levels above 20 mg/L at admission were identified as risk factors for changing the antibiotic regimen from CM to TP.

Conclusions: Generalized peritonitis and CRP > 20 gr/L were highly correlated with changing the antibiotic regimen to TP. For such patients, initial treatment with TP may result in clinical improvement and shorter hospitalization. 

Background: Rectal intussusception, rectocele and rectal prolapse are anatomic disorders in obstructed defecation syndrome. A relatively new surgical approach, Stapled Transanal Rectal Resection, was designed to treat these anomalies.

Objectives: To present our preliminary results with this technique.

Methods: Thirty patients with ODS[1] not responding to medical treatment or biofeedback were operated on with the STARR[2] technique. All the patients underwent a complete workup in the Pelvic Floor Unit. The operation was performed according to the technique described elsewhere.

Results: The patients' mean age was 67.1 years, and the median duration of symptoms was 7 years. The mean operating time was 40 minutes (range 35–80 min) and the mean hospital stay was 2 days (range 1–4 days). The mean follow-up was 26 months (range 6–48 months). ODS symptoms were ameliorated in 27 patients (90%), decreased significantly in 18, and in 9 patients the symptoms disappeared. The procedure failed in 3 patients (10%). Complications included minor bleeding that required homeostasis in eight patients during the operation. Three patients had transient tenesmus and five patients had anal pain. There were no cases of mortality or pelvic sepsis.

Conclusions: STARR is an effective and safe procedure for the treatment of obstructed defecation syndrome due to rectal intussusception, rectocele and small rectal prolapse.

Background: Mid- and lower rectum cancer is a technical challenge to the surgeon aiming to preserve the anal sphincter. The choice between abdominoperineal resection and anterior resection is often related to surgical skills.

Objectives: To evaluate the role of a specialized colorectal unit in preserving the anal sphincter mechanism in the treatment of rectal cancer.

Methods: Between 1991 and 1996, 75 patients with rectal cancer up to 12 cm from the anal verge were operated at the Sheba Medical Center. Among them, 21 patients (group 1) underwent surgery in the colorectal unit and 54 patients (group 2) in the other two surgical departments. All patients had a complete preoperative investigation and were followed for 12–90 months.

Results: Background and tumor parameters were similar for both groups. In group 1, 20 patients (95%) had low anterior resection and 1 patient (5%) had abdominoperineal resection as compared to 20 patients (37%) and 34 patients (63%), respectively, in group 2 (P < 0.005). There was no statistical difference in the systemic recurrence rate. Local recurrence was more frequent in group 2 (P < 0.05).

Conclusions: Special training in colorectal surgery enables the surgeon, in keeping with the principles of oncologic surgery, to preserve the anal sphincter mechanism in most patients with adenocarcinoma located in the mid- and lower third of the rectum.
