BACKGROUND A complex anal fistula is a challenging disease to manage. AIM To review the experience and insights gained in treating a large cohort of patients at an exclusive fistula center. METHODS Anal fistulas operated on by a single surgeon over 14 years were analyzed. Preoperative magnetic resonance imaging was done in all patients. Four procedures were performed: fistulotomy; two novel sphincter-saving procedures, proximal superficial cauterization of the internal opening and regular emptying and curettage of fistula tracts (PERFACT) and transanal opening of intersphincteric space (TROPIS), and anal fistula plug. PERFACT was initiated before TROPIS. As per the institutional GFRI algorithm, fistulotomy was done in simple fistulas, and TROPIS was done in complex fistulas. Fistulas with associated abscesses were treated by definitive surgery. Incontinence was evaluated objectively by Vaizey incontinence scores. RESULTS A total of 1351 anal fistula operations were performed in 1250 patients. The overall fistula healing rate was 19.4% in anal fistula plug ( n = 56), 50.3% in PERFACT ( n = 175), 86% in TROPIS ( n = 408), and 98.6% in fistulotomy ( n = 611) patients. Continence did not change significantly after surgery in any group. As per the new algorithm, 1019 patients were operated with either the fistulotomy or TROPIS procedure. The overall success rate was 93.5% in those patients. In a subgroup analysis, the overall healing rate in supralevator, horseshoe, and fistulas with an associated abscess was 82%, 85.8%, and 90.6%, respectively. The 90.6% healing rate in fistulas with an associated abscess was comparable to that of fistulas with no abscess (94.5%, P = 0.057, not significant). CONCLUSION Fistulotomy had a high 98.6% healing rate in simple fistulas without deterioration of continence if the patient selection was done judiciously. The sphincter-sparing procedure, TROPIS, was safe, with a satisfactory 86% healing rate for complex fistulas. This is the largest anal fistula series to date.
Background/aimsAs increasing numbers of Crohn’s disease (CD) cases are being recognized in India, so the differential diagnosis of CD and gastrointestinal tuberculosis (GITB) is becoming increasingly important. If patients are misdiagnosed with GITB, toxicity may result from unnecessary anti-TB therapy and treatment of the primary disease (ie, CD) gets delayed. We therefore aimed to assess the accuracy of various parameters that can be used to predict GITB diagnosis at index evaluation.Materials and methodsThis was a prospective, unicentric, observational study carried out in the gastroenterology department of a tertiary care hospital between August 2011 and January 2013. Patients who presented to our hospital and were suspected of having GITB were included in our study. Patients were then followed up over a 6-month period.Statistical analysisChi-square test was used to analyze the data.ResultsOf the 69 patients with GITB, 49 (71.01%) had thickening of the involved part of the colon and 33 (47.83%) had abdominal lymphadenopathy. The ileocecal valve was involved in 58 patients (84.05%) Histological detection of granulomas had 78.95% specificity, 36.23% sensitivity, and 51.40% accuracy. Tuberculosis polymerase chain reaction was found to have 78.95% specificity, 71.01% sensitivity, and 73.83% accuracy. BACTEC-MGIT culture was found to have 100% specificity, 20.29% sensitivity, and 48.60% accuracy.ConclusionAlthough histology is helpful in ruling out other conditions, TB-specific findings such as caseating granuloma and acid-fast bacilli are rarely seen. Instead, tuberculosis polymerase chain reaction has the highest diagnostic accuracy followed by BACTEC culture.
(1) Background: Several techniques for the treatment of pilonidal sinus disease (PSD) are in vogue, though none have emerged as the gold standard. Laying open (deroofing) and curettage under local anesthesia is one of the most straightforward procedures to treat PSD. In this study, the long-term follow-up in a large series was analyzed. (2) Methods: The laying open approach was performed for all types of consecutive PSD patients—simple, complicated, and abscess. The primary outcome parameter of the study was the healing rate. The secondary outcome parameters were operating time, hospital stay, time to resumption of normal work, and healing time. (3) Results: 111 (M/F–92/19, mean age-22.9 ± 5.7 years) consecutive patients were operated on and followed for 38 months (6–111 months). Of these, 24 had pilonidal abscesses, 87 had chronic pilonidal disease, while 22 had recurrent disease. Operating time and hospital stay were 24 ± 7 min and 66 ± 23 min, respectively. On average, patients could resume normal work in 3.6 ± 2.9 days and the healing time was 43.8 ± 7.4 days. Three patients were lost to follow-up. Complete resolution of the disease occurred in 104/108 (96.3%) patients, while 4 (3.7%) had a recurrence. One recurrence was due to a missed tract, while three recurrences presented after complete healing had occurred. Two patients with recurrence were operated on again with the same procedure, and both healed completely. Thus, the overall success rate of this procedure was 98.1% (106/108) with a recurrence rate after first surgery of 3.7% over a median follow-up of 38 months. (4) Conclusions: Pilonidal disease managed by laying open (deroofing) with curettage under local anesthesia is associated with a high cure rate. This procedure is effective in treating all kinds of pilonidal disease (simple, complicated, and abscess).
Background/Aims:To establish the efficacy of two-port appendectomy as an alternative to standard laparoscopic and open appendectomy in the management of acute appendicitis.Materials and Methods:Of the 151 patients included in the study, 47 patients were in the open group, 61 in two-port and 43 patients were included in the three-port group. Only patients with uncomplicated acute appendicitis were included in the study. Patients with complicated appendicitis like perforated appendix, appendicular lump and appendicular abscess were excluded from the study. Patients converted to open procedure after initial diagnosis and patients with other pathology in addition to appendicitis were also excluded. Patients with recurrent appendicitis and chronic appendicitis were excluded. The total number of excluded cases was 50. Data were compared with cases of open and three-port appendectomy.Results:The mean operative time was 43.94, 35.74, and 59.65 min (SD: 18.91, 11.06, 19.29) for open, two-port, and three-port appendectomy groups respectively. Mean length of stay in days was 3.02, 1.93, and 2.26 (SD: 1.27, 1.04,1.09) for open, two-port, and three-port appendectomy groups respectively. Surgical site infection was significantly lower (P = 0.03) in laparoscopy group as compared to that in open appendectomy group. Seven patients (4.63%) developed surgical site infection, 5 (10.63%) in the open and 2 (1.92%) in the laparoscopy group. Surgical site infection was 1.63% and 2.32% in two-port and three-port appendectomy groups respectively.Conclusions:For uncomplicated appendicitis, the two-port appendectomy technique significantly reduces operative time as well as length of hospital stay. It also reduces surgical site infection as compared to open appendectomy group.
Inflammatory myofibroblastic tumor (IMT) of bladder is an uncommon benign tumor of bladder, which is of unknown neoplastic potential, characterized by spindle cell proliferation with characteristic fibroinflammatory and pseudosarcomatous appearance. Essential criteria for the diagnosis of IMT are: spindle myoepithelial cell proliferation and lymphocytic infiltrate. Complete surgical resection is the treatment of choice.
Purpose In some anal fistulas, the internal/primary opening cannot be located even after examination and assessment on MRI or transrectal ultrasound. The efficacy of a simple new protocol to manage such therapeutically challenging fistulas was tested. Patients and Methods All anal fistula patients operated consecutively over 7 years were included in the study. A simple two-step protocol was followed for fistulas in which the internal opening was not locatable after clinical examination and MRI assessment. First, the MRI was reassessed. The site where the fistula was closest to the internal sphincter was noted. It was assumed that the internal-opening was located at that position and the fistula was treated accordingly. Second, in horseshoe anal fistulas with no apparent internal opening, it was assumed that the internal opening was located in the midline. Low fistulas were treated by fistulotomy and high fistulas by a sphincter-sparing procedure. Incontinence was evaluated by objective incontinence scores (Vaizey scores). Results A total of 757 patients were operated (median follow-up-33 months). Of these, 57 patients were excluded due to short or inadequate follow-up. In 154/700 (22%) patients, the internal opening could not be located while in 546/700 (78%), the internal opening was found. Both the groups were similar in all parameters. In the “internal-opening found” group, the fistula healed completely in 486/546 (89%) and in the ‘internal-opening not found group’, the fistula healed in 140/156 (90.9%) (p=1.01). The objective continence scores did not change significantly after surgery in both the groups. Conclusion This new protocol seems effective as a high cure rate could be achieved in ‘internal-opening not found’ fistulas which was comparable to fistula healing in the ‘internal-opening found’ group.
The term Amyand hernia refers to presence of appendix within inguinal hernia. The incidence of having a normal appendix within inguinal hernia is about 1%, whereas the finding of appendicitis in the inguinal hernia is only 0.1%.
Magnetic resonance imaging (MRI) is considered the gold standard for the evaluation of anal fistulas. There is sufficient literature available outlining the interpretation of fistula MRI before performing surgery. However, the interpretation of MRI becomes quite challenging in the postoperative period after the surgery of fistula has been undertaken. Incidentally, there are scarce data and no set guidelines regarding analysis of fistula MRI in the postoperative period. In this article, we discuss the challenges faced while interpreting the postoperative MRI, the timing of the postoperative MRI, the utility of MRI in the postoperative period for the management of anal fistulas, the importance of the active involvement and experience of the treating clinician in interpreting MRI scans, and the latest advancements in the field.
