Background: Female genital tuberculosis (FGTB) involves fallopian tubes in 95%–100% cases causing various tubal abnormalities. Objective: To evaluate the laparoscopic findings in FGTB with special reference to a new dried tree branch fallopian tubes sign. Materials and Methods: A total of eighty cases of FGTB diagnosed by demonstration of acid-fast bacilli on microscopy or culture on endometrial or peritoneal biopsy or positive endometrial or peritoneal biopsy or demonstration of epithelioid granuloma on biopsy or positive polymerase chain reaction to Mycobacterium tuberculosis on endometrial biopsy with findings of FGTB on laparoscopy or hysteroscopy were included in this prospective study. Diagnostic laparoscopy was performed in all cases. Results: Definite findings of FGTB such as caseous nodules, tubercles, beaded tubes were seen in 33 (41.2%) cases while probable findings of FGTB such as congested and hyperemic fallopian tubes, hydrosalpinx obstructed tubes, pelvic adhesions, and straw-colored fluid were observed in rest 47 (58.8%) cases. A new dried tree branch fallopian tubes sign was seen in 7 (8.0%) cases being bilateral in 4 (5%) and unilateral in 3 (3.7%) cases. Conclusion: The new sign Sharma's dried tree branch fallopian tubes sign appears to be a useful sign in FGTB. However, larger prospective studies are needed before its routine recommendation in clinical practice.

| Introduction|| |
As per the World Health Organization (WHO) report 2016, of 9 million tuberculosis (TB) cases annually globally, 3.2 million cases occur in women with 480,000 deaths. The WHO has recommended directly observed treatment short course (DOTS) strategy management of TB, and the same has been implemented by the Revised National TB Control Program (RNTCP) of Government of India for both pulmonary and extrapulmonary TB (EPTB) with almost 86% cure rate.,
Female genital TB (FGTB) is an important variety of EPTB and is an important cause of significant morbidity and short and long-term sequelae such as infertility, chronic pelvic pain, tubo-ovarian masses, and menstrual dysfunction in infected women, especially in developing countries like India.,,,,,,
There can be dilemma in diagnosis of FGTB due to paucibacillary nature of the disease. The gold standard diagnostic methods include detection of acid-fast bacilli (AFB) on microscopy or culture on endometrial or peritoneal biopsy or demonstration of epithelioid granuloma on histopathology of endometrial or peritoneal biopsy., However, they are positive in some cases only due to paucibacillary nature of disease.,,
Polymerase chain reaction (PCR) is highly sensitive but has high false positivity and alone should not be used to make diagnosis of FGTB.,
Gene Xpert is a newer diagnostic modality with nearly 100% specificity but lower (30%–40%) sensitivity.
Imaging modalities such as hysterosalpingography, ultrasound, computed tomography (CT) scan, magnetic resonance imaging (MRI), and positron emission tomography (PET) are mainly useful for tubercular tubo-ovarian masses but may give conflicting reports.,,
Endoscopic visualization by (both laparoscopy and hysteroscopy) has been used successfully for diagnosis of FGTB., Laparoscopy and dye test is the most reliable test to diagnose FGTB, especially tubal, ovarian, and peritoneal disease in both pelvic and abdominopelvic TB. Various laparoscopic findings include caseous nodules, tubercles, hyperemic and congested tubes, pelvic and abdominal adhesions, hydrosalpinx, pyosalpinx, and straw-colored fluid in pouch of Douglas., Fallopian Tubes often become dilated (hydrosalpinx), may have pus (pyosalpinx), or may become rigid in FGTB. We present our findings on new laparoscopic sign of dried tree branch fallopian tubes sign in FGTB in which tubes look rigid-like branches of a dried tree.
| Materials and Methods|| |
A total of eighty cases with diagnosis of FGTB on detection of AFB on microscopy or culture, on endometrial aspirate or peritoneal biopsy or demonstration of epithelioid granuloma on endometrial or peritoneal biopsy and or laparoscopic findings of FGTB were taken in this prospective study. The study was part of our large TB project which was ethically cleared from the Institute Ethics Committee. The study was conducted between June 2011 and June 2016 at a tertiary referral center in Northern India.
Informed written consent was taken from all the study participants. All patients underwent a detailed clinical and laboratory evaluation for FGTB. Diagnostic laparoscopy with or without hysteroscopy was performed in all patients. Careful inspection of whole abdominal cavity was made by rotating the laparoscope by 360° in the abdomen for any tubercular lesions and abdominal and pelvic adhesions. All tuberculous lesions such as tubercles, caseous nodules, shaggy areas, nodular or patchy salpingitis, hydrosalpinx, pyosalpinx, beading of tubes, hyperemia and congestion of tubes and patency of tubes and looks of tubes were carefully observed and findings were carefully recorded. After confirmation of diagnosis of FGTB, all women were given Category I antitubercular therapy (ATT) under RNTCP of India under DOTS strategy using isoniazid, rifampicin, pyrazinamide and ethambutol thrice a week for 2 months (intensive phase) followed by rifampicin and isoniazid thrice a week for 4 months (continuation phase). All women were followed up every 2 months for liver function tests and any adverse effects.
Descriptive statistics such as mean, median, standard deviation, and range values were calculated for study characteristics such as age, body mass index (BMI), and duration of infertility. Continuous variables were tested for normality assumptions using Kolmogorov–Smirnov tests. Chi-square test or Fisher's exact test was used for frequencies of categorical variables. A two-tailed probability level P< 0.05 was considered for statistical significance. All data analyses were carried out using IBM SPSS statistics for windows, version 19.0. Armonk, New York, IBM Corp.
| Results|| |
Characteristics of the patients and disease at baseline are shown in [Table 1]. Thus, age ranged between 20 and 45 years with mean being 28.5 ± 3.25 years. The mean parity was 0.6 while the mean BMI was 22.3 ± 2.15 kg/m 2. Infertility was seen in all 80 (100%) cases with primary infertility in 62 (77.5%) and secondary infertility being in 18 (22.5%) cases. The mean duration of infertility was 4.2 years. Various menstrual characteristics are also shown in [Table 1]. Normal menstrual cycles were seen in 22 (27.5%) cases, hypomenorrhea in 25 (31.2%) cases, oligomenorrhea in 26 (32.5%) cases, primary amenorrhea in 2 (2.5%), secondary amenorrhea in 10 (12.5%) cases while menorrhagia was seen in 3 (3.75%) women.
Fever, weight loss, and anorexia were seen in 18 (22.5%), 29 (36.2%) and 31 (38.7%) women, respectively. Abdominal pain was observed in 5 (6.25%) women, chronic pelvic pain in 33 (41.2%) cases, abdominal mass in 6 (7.5%), pelvic or adnexal mass in 30 (37.5%) cases with some women having more than one symptom. Diagnosis of FGTB was made as per findings in [Table 2] with some women having more than one finding. Positive AFB on microscopy of endometrial aspirate was seen in 10 (12.5%) cases, culture of AFB on endometrial aspirate was positive in 11 (13.7%) cases, positive AFB on microscopy or culture of peritoneal biopsies in 7 (8.7%) cases, epithelioid granuloma on endometrial biopsy in 23 (28.7%) cases, or peritoneal and caseous nodule biopsy in 18 (22.5%) cases. Positive PCR on endometrial or peritoneal fluid was seen in 76 (95%) cases. Hysterosalpingography (HSG) was not routinely performed in FGTB cases due to risk of flare up of disease. However, in some cases of unsuspected FGTB, HSG had already been done from outside. It showed marked narrowing of uterine cavity with appearance of rigid dried tree branch in both fallopian tubes with no spill (blocked tubes) [Figure 1].

Definite findings of FGTB on laparoscopy were seen in 33 (41.2%) cases while probable findings of FGTB on laparoscopy were seen in 47 (58.8%) cases.
Various diagnostic laparoscopic findings in FGTB cases are shown in [Table 3]. Tubercles were observed on fallopian tubes, ovaries, uterus, pouch of Douglas, or pelvic peritoneum in 33 (41.2%) cases. Hydrosalpinx was observed in 19 (23.7%) cases, pyosalpinx in 4 (5%) cases, beaded tubes in 7 (8.7%) cases, shaggy area on uterus, fallopian tubes, or pelvic peritoneum were observed in 32 (40%) cases, congested and hyperemic tubes in 33 (41.2%) cases, caseous nodules on fallopian tubes, pelvic peritoneum [Figure 2], or pouch of Douglas in 26 (32.5%) cases, encysted ascites in 13 (16.2%) cases, abdominal adhesions in 28 (35%) cases and pelvic adhesions in 33 (41.2%) cases. Fallopian tubes were rigid dried tree branch like with no distension on introduction of dye (Sharma's) dried tree branch sign in 7 (8.7%) cases which was bilateral in 4 (5%) [Figure 3] and unilateral in 3 (3.7%) cases [Figure 4].

Due to chronic tuberculous infection of fallopian tubes and cornual blockage, the tube becomes hard, nonpliable, nondistensible and nonelastic like the branch of dried tree (dried tree branch sign). It does not take any dye due to cornual blockage. The overall incidence of dried tree fallopian tubes sign was 8.7% being bilateral in 5% cases and unilateral in 3.7% cases.
Diagnostic laparoscopy in FGTB is hazardous and difficult as shown in [Table 4]. Difficulty in pneumoperitoneum was observed in 19 (23.7%) cases, difficulty in insertion of trocar and cannula was seen in 11 (13.7%) cases, difficulty in visualization of pelvic organs due to adhesions was seen in 13 (16.2%) cases, excessive bleeding was seen in 7 (8.7%) cases, subacute intestinal obstruction was observed in 7 (8.7%) cases, while flare up of tuberculosis was seen in 4 (5.0%) cases. Excessive bleeding was managed by cauterization of bleeder. Subacute intestinal obstruction and flare up of TB cases were managed by keeping the patients admitted for 2–3 days in hospital and were all controlled on conservative treatment. None of the patients needed laparotomy.

The various complications of ATT are shown in [Table 5]. The compliance rate was 100% with four women needing readjustment of ATT due to derangement of liver function tests but all women completed ATT. The treatment was given under supervision with DOTS with responsibility of treatment being on DOTS provider.
| Discussion|| |
FGTB is a common disease in developing countries causing significant morbidity and short- and long-term sequelae, especially infertility.,,,,, Fallopian tubes are involved in 90%–100% cases, uterus in 50%–80% cases, ovaries in 20–30 cases, cervix in 5–15% cases, vagina and vulva in 1% cases., Involvement of fallopian tubes is usually bilateral. Various types of TB salpingitis are TB endosalpingitis, exosalpingitis, interstitial TB salpingitis, and salpingitis isthmica nodosa., In TB endosalpingitis, the infection starts from endosalpinx and is usually through hematogenous route of spread with thickening, enlargement and tortuosity of fallopian tubes. Sometimes unilateral or bilateral pyosalpinx may be formed due to caseation in tubal wall with blockage of both ends of fallopian tubes due to fibrosis. Endosalpinx may be edematous, hyperplastic, or may be totally destroyed.,
In tuberculous exosalpingitis, disease starts at muscularis mucosa of fallopian tubes with congestion of tubes. Later, there occur beaded tubes with calcifications and tubal blockage, tubo-ovarian masses, hydrosalpinx, pyosalpinx, and massive adhesions formation.,
Diagnosis of FGTB is made by demonstrating AFB on microscopy and culture on endometrial or peritoneal biopsy or histopathological demonstration of epithelioid granuloma on endometrial or peritoneal biopsy, but diagnosis may be missed due to paucibacillary nature of disease.,,, PCR is highly sensitive but may be false positive and alone is not diagnostic of FGTB., Imaging modalities (HSG, ultrasound, CT scan, MRI, and PET) are useful in only TB tubo-ovarian masses but are not diagnostic of TB.,,
Diagnostic hysteroscopy and laparoscopy are very useful in diagnosis of FGTB by demonstration of tubercles, caseous nodules, and adhesions.,, Laparoscopy and dye test remains the mainstay of diagnosis in FGTB and may show definite findings of FGTB (tubercles, caseous nodules, and beaded tubes) or probable findings of FGTB (congested tubes, hydrosalpinx, obstructed lumen, pelvic and abdominal adhesions, and encysted ascites). In the present study, definite findings of FGTB were seen in 33 (41.2%) cases, while probable findings were seen in 47 (58.8%) cases. In our previous studies on FGTB, we observed hanging gall bladder and ascending colonic adhesions in cases of abdomino pelvic TB.,
We also observed blue python sign in fallopian tubes on laparoscopy and dye test in FGTB cases with alternate dilation and constriction of fallopian tubes resembling blue python  due to damage of fallopian tube by TB with partial blockage. We also observed Sharma's kissing fallopian tubes sign in a case of FGTB with fusion of fimbrial ends of both fallopian tubes due to caseous material.
We observed dried tree branch sign in 7 (8.7%) in FGTB (bilateral in 5%, unilateral in 3.7%) cases in which the fallopian tubes are rigid pipes with no uptake of dye due to tubal blockade and fibrosis resembling branchs of a dried tree.
| Conclusion|| |
The new sign Sharma's dried tree branch fallopian tubes sign appears to be a useful sign in FGTB. However, larger prospective studies are needed before its routine recommendation in clinical practice.
