"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

Dr. Mamta Gupta,
"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

A colocutaneous fistula is a type of enterocutaneous fistula where communication exists between the colon and the skin of the abdominal wall. The present case report is of postoperative colocutaneous fistula in a 32-year-old male patient, who had undergone left open nephrectomy. This is unique, as nephrectomy is not a procedure that is usually associated with such colocutaneous fistulas, particularly as this was a case of non functioning kidney and was not associated with severe inflammation or adhesions, which are usually prerequisites for a fistula to arise. Following surgery, patient developed feculent discharge from the drain in the early postoperative period. A Contrast Enhanced Computed Tomography (CECT) scan was done to evaluate the cause of the leak was done, which showed a colocutaneous fistula arising from the proximal descending colon with an abscess surrounding the fistula tract. The abscess was drained and conservative management was initially attempted to allow for spontaneous resolution of the fistula as spontaneous closure is the norm, when there are no unfavourable factors hindering spontaneous closure, as was the case in this patient. However, despite all factors being favourable for spontaneous closure of the fistula, it failed to occur in the present case. Furthermore, this patient required multiple surgical procedures, which is also unusual for a fistula such as this, where all factors being favourable for its spontaneous healing. Closure of the fistula was finally achieved by resection of the fistula tract along with the segment of the bowel containing the internal opening. The present case report highlighted the challenges posed by cases of colocutaneous fistulas and shows that thorough knowledge of all the treatment modalities available for its treatment, is required to successfully treat it.

Case Report

This is a case report of 32-year-old male diabetic patient on regular follow-up who presented with complaints of burning micturition and increased frequency. After performing routine urine examination, the patient was diagnosed with urinary tract infection. Further workup revealed deranged renal function test parameters due to non functioning left kidney secondary to diabetic nephropathy, confirmed by Diethylenetriamine Pentaacetate (DTPA) scan. Following this left open nephrectomy was undertaken to remove the risk of future complications due to the non functioning kidney. Nephrectomy was performed through a left flank incision and intraoperatively left kidney was found to be shrunken, discoloured and free of adhesions. On postoperative day 3, patient developed feculent discharge from the drain placed at surgical site, with an output of ~150 mL per day. CECT scan of the abdomen and pelvis on postoperative day 6 was done which revealed an abscess with colocutaneous fistula of length of 7 cm and diameter ~7 mm in the wall of the colon without any distal obstruction as shown in (Table/Fig 1). As it was a low output fistula, with no history of underlying bowel disease and all other factors were favourable for spontaneous healing, patient was initially managed conservatively. Conservative management in this case included bowel rest, parenteral nutrition, antibiotics, drainage of abscess and regular dressings.

Conservative management was successful in controlling the local infection but feculent discharge from fistulous opening continued. Since conservative management failed to bring about spontaneous resolution of the fistula, patient was taken up for a defunctioning ileostomy, three months after nephrectomy (1). This was done to achieve diversion of intestinal contents away from fistula site to allow the affected segment to be rested and promote healing of the fistula. Diversion procedure was unsuccessful, in reducing output to ~30-50 mL/day, however fistula once again persisted as shown in (Table/Fig 2). Spontaneous closure did not occur even after six months of ileostomy.

Ultimately definitive surgical procedure was performed in the form of excision of the fistulous tract with resection of the involved segment of colon and side-to-side colocolic anastomosis. Intraoperatively fistulous tract was noted, arising from proximal descending colon as shown in (Table/Fig 3).

Resected segment of the descending colon along with the fistulous tract (Table/Fig 4) was sent for Histopathological Examination (HPE), which revealed signs of chronic inflammation of the fistulous tract with no epithelioid granuloma and unremarkable colonic mucosa and propria (Table/Fig 5). Patient recovered well after the surgery and was discharged with ileostomy. Patient was regularly followed-up and fistula site healing was noted. Patient was taken up for ileostomy reversal two months after resection and anastomosis. Following ileostomy reversal, patient was passing stools normally and was further followed-up for six months, with no evidence of fistula recurrence.

Discussion

Colocutaneous fistula is a type of Gastrointestinal (GI) fistulas, constituting ~10-30% of all GI fistulas (1),(2). Common causes of GI fistulas are: Diseased bowel extending to surrounding epithelialised structures, extra-intestinal disease extending into normal bowel, trauma to bowel and anastomotic disruption (3). GI fistulae can be classified anatomically, physiologically and aetiologically. Anatomically, fistula may originate from stomach, duodenum, proximal or distal small bowel, large bowel or rectum. Physiologically, they are classified based on output as being either low output (<200 mL/24 hour), moderate output (200-500 mL/24 hour) or high output fistulas (>500 mL/24 hour) (4),(5). Colocutaneous fistulas, in particular are those fistulae in which communication exists between colon and the external skin (6). They are further classified aetiologically into spontaneous or postoperative. About 25% of fistulas occur spontaneously, in the setting of cancer, post irradiation or inflammatory conditions like Inflammatory Bowel Disease (IBD), diverticular disease, or ischaemic bowel, with IBD being the most common. The remaining three-quarters of fistulas occur in the postoperative setting, most commonly subsequent to procedures performed for malignancy, IBD, or adhesive bowel obstruction (4),(5).

In present case report, fistula was developed following left open nephrectomy. Postoperative colocutaneous fistulas occur due to anastomotic leakage, breakdown of enterotomy closure, missed enterotomy or occasionally after instrumentation or drainage of an appendiceal, diverticular fluid collection or abscess. Fistula formation is predisposed by factors such as distal obstruction, intrinsic intestinal disease (e.g., Crohn’s disease), radiation enteritis, or a hostile abdominal environment, like peritonitis/abscess. The risk is also higher in emergencies when the patient may be malnourished or poorly prepared. Factors which prevent spontaneous closure of fistulas are high output, severe disruption of intestinal continuity, active IBD of involved segment, malignancy, radiation enteritis, distal obstruction, undrained abscess cavity, foreign body in fistula cavity, fistula tract <2.5 cm, epithelisation of tract (1),(6). The first step in the management of a colocutaneous fistula is to prevent its occurrence. Reducing the likelihood of an anastomotic leak requires adherence to sound surgical principles and proper techniques (7). If a fistula forms, management involves several phases that are applied systematically and simultaneously. The initial phase is aimed at stabilisation of the patient, with prompt fluid resuscitation and electrolyte replacement followed by sepsis control, which may require all infections to be adequately drained, either percutaneously or operatively, along with appropriate antibiotic administration (4),(5),(6),(8). Nutritional support is paramount in this phase with total parenteral nutrition being particularly valuable, especially for high output fistulas (4),(5),(6),(8). Wound and fistula care using a stoma bag with applications of zinc oxide, aluminum paste ointment and occasionally effluent control by intubation of the fistula tract with a drain maybe necessary (4),(5),(6),(8),(9). Next phase involves evaluation of anatomical and aetiological characteristics (4),(5),(6),(8). This allows us to identify factors which are unfavourable for spontaneous healing of fistula and correct them, if possible (6). With such an orchestrated approach, approximately 60-90% of fistulas with favourable factors close spontaneously, with 90% closing within 4-6 weeks, and <10% closing in 2-3 months (4),(10),(11). For patients in whom fistulas fail to resolve with conservative management, operative intervention will eventually be necessary (4),(5),(6),(8).

A convalescent period of >6 weeks to allow recovery of immunologic competence, improvement of nutritional status, and resolution of period of dense inflammatory reaction is imperative, for the success of surgical intervention (1),(4),(5),(6),(8). Surgery can be either single-staged procedure or two-staged procedure (4),(5),(6),(8). Early procedures are typically limited to drainage of infected fluid/collections, defunctioning, or exteriorisation of the defect. Preferred option for definitive repair is excision of fistulous tract and resection of the involved segment of intestine and primary anastomosis or exteriorisation of both ends of the intestine, if primary anastomosis is deemed unsafe (4),(5),(6),(8). Basic surgical considerations include attempting a one-stage procedure, careful adhesiolysis, addressing compromised tissues with wedge excision or intestinal resection, covering sutures with viable tissues, and avoiding friable areas.

As discussed in a study by Kumar P et al., most colocutaneous fistulas have postoperative aetiology and various factors need to be taken into account when planning the management of such cases (12). As shown by Hajong R et al., and Balachandra D et al., there are a multitude of factors to be considered when planning management of colocutaneous fistula (13),(14). It is uncommon for any colocutaneous fistula to resist spontaneous closure, once all influences that are unfavourable for such as outcome have been mitigated. However, the present case was unusual, since it required surgical intervention, in spite of conditions favouring its spontaneous resolution. Despite the absence of any unfavourable factors, the fistula failed to resolve spontaneously with conservative management. A defunctioning ileostomy was first attempted to provide bowel rest to the affected segment and facilitate spontaneous closure of the persisting colocutaneous fistula. A two-stage procedure is not commonly used, but in this particular case, two-staged procedure was undertaken, however, all factors were favourable for spontaneous resolution. All efforts to promote spontaneous closure ultimately failed, thus requiring definitive repair i.e., resection of the involved segment with primary anastomosis, to finally resolve this determined fistula.

Conclusion

The present case report was of colocutaneous fistula that developed following left open nephrectomy procedure in a diabetic pateint. Conservative management failed to bring about spontaneous resolution of the fistula, so defunctioning ileostomy was done. This procedure was also unsuccessful, so definitive surgical procedure was performed in the form of excision of the fistulous tract with resection of the involved segment of colon and side-to-side colocolic anastomosis. Surgeons should be aware of all the factors, that hinder spontaneous closure of fistula. Sound practice of surgical principles along with timely decision making, was employed in the present case for best outcome of this seemingly simple, but challenging case.
