Rectal prolapse associated with traumatic fecal incontinence is a rare clinical combination. This study was designed to assess Delorme＇s operation with sphincteroplasty as a surgical management of this combination in terms of recurrence and improvement of fecal incontinence. In this prospective study, we enrolled patients suffering from short, full-thickness rectal prolapse associated with traumatic fecal incontinence who had been admitted to Alexandria main University Hospital during the period of may 2010-January 2013. Preoperative data including cause of trauma, duration of symptoms, results of anal manometry, and degree of fecal incontinence using Wexner score were collected from all patients. Delorme＇s procedure with overlap sphincteroplasty was done in all patients. Recurrence of prolapse and improvement of fecal incontinence were assessed after 1, 3, 6 and 12 months. The study included 13 patients aged （32±8.7） years, 9 females and 4 males. Cause of sphincteric injury included previous anal surgery in 7 patients and normal labor in 6 patients. Duration between sphinctefic injury and operation was （8.08±2.47） months. Preoperative Wexner＇s mean score was 16.07±3.4. Early postoperative complications included superficial wound infection （69.2%）, minor wound dehiscence （61.5%）, and postoperative bleeding （7.6%）. Recurrence was detected in 1 patient at 6 month follow-up. Wexner＇s score showed significant improvement for all patients after 6 months （4.00±2.04）. In conclusion, combination of Delorme＇s procedure and sphincteroplasty for treatment of patients with short complete rectal prolapse associated with traumatic fecal incontinence is a safe, effective surgical management with satisfactory results regarding anatomical and functional outcomes.

Abscess of the caudate lobe of the liver, a rare disease with a challenging management: a case report

引用

The Journal of Biomedical Research 2013年第5期27卷 430-434页

作者： Nasser A. Al Amer walid m. abd el maksoud Consultant of General Surgery Aseer Central Hospital Assistant Professor General Surgery Department Faculty of Medicine King Khalid University

We reported a rare case of abscess of the caudate lobe of the liver in a 60-year old man. We first tried computed tomography （CT） guided percutaneous drainage of the abscess but failed to eradicate the infection. Deterioration of the general condition of the patient necessitated open surgical drainage, which resulted in cure of the abscess. The peculiar anatomical location of caudate lobe abscess introduces a great challenge for the surgeon in plan- ning the appropriate management and paucity of patients with caudate lobe abscess has led to lack of guidelines for management. The non-operative interventional radiology approach has become the therapeutic choice for pyo- genic liver abscess, but is it applicable also for caudate lobe abscess？

The Journal of Biomedical Research 2017年第5期31卷 462-465页

作者： Dafer m. A1 Shehri abdullah K. Asiri walid m. abd el maksoud General Surgery Aseer Central Hospital Abha Saudi Arabia Faculty of medicine King Khalid University Abha Saudi Arabia. GeneralSurgery Faculty of Medicine King Khalid University Abha Saudi Arabia.

We describe a case of right ilio-psoas abscess caused by stump appendicitis 14 years after open *** appendicitis is a rare complication of appendectomy. Right ilio-psoas abscess was diagnosed in an immunecompetent patient and treated by ultrasound guided percutaneous drainage twice without identifying the cause of the abscess. The patient did not improve until diagnostic laparoscopy was performed revealing a long stump appendicitis to be the origin of infection. It was treated by completion appendectomy. Surgical exploration may be necessary in persistent or recurrent ilio-psoas abscesses. We identified 4 reported cases of post-appendectomy ilio-psoas abscess but without recognizing the cause of the abscess and its relation to appendectomy. This is the first reported case of ilio-psoas abscess that developed as a complication of stump appendicitis.

The stability constants of complexes of 2-hydrazinobenzoic acid and 4-hydrazinobenzoic acid with Ni (Ⅱ), Cu (Ⅱ), Zn (Ⅱ), Cd (Ⅱ), and Hg (Ⅱ) were determined potentiometricaIly at different temperatures. The thermodynamic parameters, △G0, △H0, and △S0 were calculated and proved that the complexation process is spontaneous and endothermic. The thermodynamic functions were analyzed in terms of electrostatic and non-electrostatic components and the results reveal that ionic bonds are formed between the studied ligands and metal ions. Conductometric titration was shown that the stoichiometry of the formed complexes are m:L and m:2L. The structure of the prepared solid complexes was characterized using IR, 1H NmR, 13C NmR spectroscopies as well as X-ray diffraction technique. Finally electrical conductivity of the ligands and their copper complexes was measured and shown that the ligands have a semiconductor behaviour.
