Sharma's sigmoid colonic adhesive band - A new laparoscopic sign in female genital tuberculosis

Background: Female genital tuberculosis (FGTB) is a form of extra pulmonary tuberculosis (EPTB) affecting women of reproductive age group. It causes significant morbidity in women especially infertility particularly in developing countries. Diagnosis is by endometrial sampling for acid fast bacilli (AFB) microscopy, culture, gene Xpert, polymerase chain reaction (PCR), histopathological evidence of epithelioid granuloma and by laparoscopic findings suggestive of tuberculosis.

Aim: Present study was conducted to observe the prevalence of a new "Sharma's Sigmoid colonic adhesive band "in FGTB on laparoscopy.

Methods: It was a prospective study in a tertiary referral center as a part of our ongoing tuberculosis project on 148 infertile women found to have FGTB on microbiological or laparoscopic findings over previous 10 years. A new laparoscopic "Sharma's Sigmoid colonic adhesive band" was looked for in these cases on laparoscopy.

Results: The mean age, parity and duration of infertility and incidence of poor socioeconomic status was 26.9 years, 0.49, 5.3 years and 65.54% respectively. All patients had infertility with 83.78% primary and 16.22% secondary infertility while menstrual dysfuction especially hypomenorrhoea (31.75%), oligomenorrhoea (32.48%) were seen in respective cases. Constitutional symptoms like pyrexia (21.62%), weight loss (31.75%) appetite loss (33.5%) and abdominal pain (11.48%) and pelvic pain (27.70%) or abdominal mass (8.78%) and pelvic masses (35.81%) were also seen. Diagnosis of FGTB was made on endometrial or peritoneal biopsy microscopy or culture for AFB or positive gene Xpert or positive polymerase chain reaction (PCR) or histopathological demonstration of epithelioid granuloma or on laparoscopic findings of FGTB. Various laparoscopic findings were tubercles on pelvic organs (45.27%), shaggy areas (white deposits) on pelvic organs (43.91%),beaded or convoluted tubes (9.45%), hyperemic tubes (29.05%), caseous nodules in pelvis (29.72%), encysted ascites (14.18%), abdominal adhesions (32.43%), pelvic adhesions (42.56%), calcified and rigid tubes (6.08%). The new laparoscopic sigmoid colonic adhesive band was seen in 49 (33.10%) patients of FGTB.

Conclusion: The new laparoscopic "Sharma's Sigmoid colonic adhesive band" appears to be an important finding in patients with FGTB.
