In this study, we retrospectively evaluated all attacks of diarrhoea in our renal transplant recipients that came to our medical attention between 1985 and 2000. Also, the clinical features of patients with diarrhoea were compared with the features of recipients without diarrhoea. We diagnosed 41 attacks of diarrhoea in 39 (12.6%) of 308 renal transplant recipients during this time period. An aetiology was detected in 33 (80.5%) of all diarrhoeal episodes and in seven (17.1%) of those the specific agent was diagnosed with the help of stool microscopy. The most frequent causes of diarrhoeal attacks were infectious agents (41.5%) and drugs (34%). Six (14.6%) episodes of diarrhoea were chronic and six were nosocomial. About two-thirds of diarrhoea developed within the late post-transplant period (>6 months). When recipients with diarrhoea were compared with those without diarrhoea, it was seen that diarrhoeal patients had significantly higher creatinine and significantly lower albumin levels when compared with the latter group (p < 0.05). Also, the frequency of antibiotic usage was significantly higher in diarrhoeal patients than in the control group (p < 0.05). Four (10.2%) patients with diarrhoea died despite institution of the appropriate therapy. Two of these deaths were primarily related to diarrhoea and the aetiological agent was Clostridium difficile in both these cases. During the 15-yr study period, 3.6% of all deaths and 5.1% of infection-related deaths in transplant recipients were secondary to diarrhoea. As a result, we observed that infections and drugs were the most frequent causes for diarrhoea in our series of renal transplant recipients. Also, diarrhoea was an important cause of mortality in this patient population.

Background There are various advantages and disadvantages attributed to superficial circumflex iliac artery perforator (SCIP) flap. The aim of this study is to evaluate the versatility and reliability of free SCIP flap by performing a systematic review and meta-analysis of the literature in terms of flap characteristics, pedicle types, and outcomes, including the different types of flap elevations. Methods PubMed, Embase OVID, and Cochrane CENTRAL were searched up to January 2019. All original articles and case reports published in English were included in the analysis. Anatomic descriptions, cadaveric studies, conference presentations, letter to the editors, local SCIP flaps, and review articles were excluded. Results A total of 36 articles including 907 SCIP flaps were available for the analysis. The most frequent causes of defects were tumors (38.2%) and lower extremities were the most common recipient areas (62.7%). The average flap dimension was 73.3 ± 23.0 cm2 with a pedicle length of 5.0 ± 0.6 cm. Vessel diameter average was 0.67 ± 0.12 mm. The average number of deep branch and superficial branch used per study was 14.4 ± 8.7 (18%) and 93.3 ± 75.0 (84%), respectively. Flap failure rate and complication rate were 2.7 and 4.2%, respectively. Conclusion SCIP flaps have been shown to be versatile in various aspects of reconstruction. The attributed disadvantages such as having short pedicle and small vessel diameter do not seem to limit the variable usage of this flap. Therefore, SCIP flap should be considered a workhorse flap.
