Endoscopic management of symptomatic pancreatic fluid collections (PFCs) is now considered to be first line therapy. Expanded use of endoscopic ultrasound (EUS) techniques has resulted in increased applicability, safety, and efficacy of endoscopic transluminal PFC drainage. Steps include EUS-guided trangastric or transduodenal fistula creation into the PFC followed by stent placement or nasocystic drain deployment in order to decompress the collection. With the remarkable improvement in the available accessories and stents and development of exchange free access device; EUS drainage techniques have become simpler and less time consuming. The use of self-expandable metal stents with modifications to drain PFC has helped in overcoming some previously encountered challenges. PFCs considered suitable for endoscopic drainage include collection present for greater than 4 weeks, possessing a well-formed wall, position accessible endoscopically and located within 1 cm of the duodenal or gastric walls. Indications for EUS-guided drainage have been increasing which include unusual location of the collection, small window of entry, nonbulging collections, coagulopathy, intervening varices, failed conventional transmural drainage, indeterminate adherence of PFC to the luminal wall or suspicion of malignancy. In this article, we present a review of literature to date and discuss the recent developments in EUS-guided PFC drainage.

The histologic analysis of gastrointestinal stromal tumors (GISTs) is a common method to detect the mitotic activity and to subsequently determine the risk of GISTs for malignancy. The potential false negative error due to inadequate yield of specimens and actual determination of malignancy risk requires analysis of the whole tumor. We aimed to assess the role of contrast enhanced endoscopic ultrasound (CE-EUS) in the management of GISTs. Two authors individually did review of English literatures to identify nine peer-reviewed original articles using keywords- contrast endoscopic ultrasound, GIST and submucosal tumor. Studies were heterogeneous in their aims looking either at differentiating submucosal lesions from GISTs, estimating malignant potential of GISTs with histologic correlation or studying the role of angiogenesis in malignant risk stratification. CE-EUS had moderate to high efficacy in differentiating GISTs from alternative submucosal tumors. CE-EUS had a higher sensitivity than EUS-guided fine needle aspiration, contrast computed tomography and Doppler EUS for detection of neo-vascularity within the GISTs. However, the evidence of abnormal angiogenesis within GIST as a prognostic factor needs further validation. CE-EUS is a non-invasive modality, which can help differentiate GISTs and provide valuable assessment of their perfusion patterns to allow better prediction of their malignant potential but more experience is needed.

Introduction: Pre-operative identification of patients with
inadequate hamstring graft for anterior cruciate ligament
reconstruction is still a subject of interest. The purpose of
this study is to correlate dimension of a harvested
dimensions graft with patient physical anthropometric
variables.
Materials and methods: This cohort study included 280
patients (male = 226, female = 54) scheduled for primary
anterior cruciate ligament (ACL) reconstruction.
Interrelationships between quadruple semitendinosus (ST)
graft and anthropometric parameters (age, sex, height,
weight, and BMI) were assessed using Pearson Correlation
test and regression analysis. Difference among gender was
analysed using Mann Whitney and t test. The observed graft
diameter was also compared with the literature using Bland
– Altman plot.
Results: Mean age of cohort was 29 years (range, 17-50
years), mean height was 1.69m (range, 1.6-1.9m), mean
weight was 75 kg (range, 50-116kg) and mean BMI was
26kg/m2 (range 16.65-40.40kg/m2). Mean quadruple length
of harvested ST graft was 7cm (7.1±0.6 cm, range, 5.6-
8.8cm) and mean diameter was 8mm (8.2±0.8mm, range,
6.5-10mm). Only height and weight were significantly
correlated with graft length and diameter in both sex (p value
<0.05). Female, compared to male, had significantly smaller
(p<0.0001) and thinner graft (p<0.0001). There was a strong
agreement between the literature and our observed graft
diameter, but with an overestimated graft diameter in 18.5%
of the cases.
Conclusion: Among anthropometric parameter, only height
and weight had moderate positive correlation with graft
diameter. Males had longer and wider ST graft in contrast to
age-matched female group.

Introduction: Few authors have addressed risk factors
related to an ipsilateral graft rupture and contralateral
anterior cruciate ligament (ACL) injury after return to sports
(RTS) following primary ACL reconstruction.
Material and Methods: Patients with ACL re-injury to
either knee after successful primary ACLR were included in
Group I and those with no further re-injury were included in
Group II. Variables including age, gender, side, body mass
index (BMI), thigh atrophy, anterior knee laxity difference
between both knees measured by KT-1000 arthrometer,
mean time of return to sports (RTS), graft type, type of game,
mode of injury, Tegner Activity Score, hormone levels,
femoral tunnel length (FTL), posterior tibial slope (PTS) and
notch width index (NWI) were studied. Binary logistic
regression was used to measure the relative association.
Results: A total of 128 athletes were included with 64 in
each group. Mean age in Group I and II were 24.90 and
26.47 years respectively. Mean follow-up of Group I and
Group II were 24.5 and 20.11 months respectively.
Significant correlation was present between ACL re-injury
and following risk factors; PTS of >10º, KT difference of
>3.0mm, thigh atrophy of >2.50cm and time to RTS <9.50
months P value <0.05). No correlation was found with age,
sex, BMI, type of game, Tegner Activity Score, mode of
injury, NWI, size of graft, FTL and hormone levels.
Conclusion: Possible risk factors include PTS of ≥ 10º, KT
difference of ≥ 3.0mm at 1 year follow-up, thigh atrophy of
≥ 2.50cm at 1 year follow-up and RTS <9.5 months after
primary ACLR.

Introduction: The preferred management of medial
meniscus tears has notably moved from meniscectomies
towards repair. With a higher volume of meniscal repairs
being done all across the world with every passing day, the
lack of an objective and definitive sign suggesting the
adequacy of its repair is daunting. The purpose of our study
was to introduce a unique and novel arthroscopic sign
formed after adequate repair of the medial meniscus, the
AMR (Adequacy of Medial meniscus Repair) sign. We
hypothesised that it is not only the objective end point for
repair, but can also form the indicator for excellent clinical,
functional, and radiological outcome even in the long term.
Materials and methods: This was a multicentric,
prospective study initiated by the corresponding author, and
the findings validated subsequently by the other authors.
Overall, it included 804 patients of isolated medial meniscus
tear operated with arthroscopic all-inside technique between
January 2014 and December 2017. Patients were segregated
into three groups based on whether an S-shaped curve in the
free, inner edge of the medial meniscus sign was formed
post-repair, lost after further tightening, or not formed upon
subjective completion of repair. All the patients were
followed-up and evaluated based of medial joint line
tenderness, McMurray’s test for medial meniscus, IKDC
score, WOMET score, and radiologically using an MRI at
the terminal follow-up.
Results: The mean terminal follow-up was 42.34±4.54
months. There was significant (p<0.01) improvement in all
patients at the terminal follow-up post-surgery, irrespective
of the group. The group in which AMR sign was formed and
maintained showed a significantly better functional outcome
on terminal follow-up as well as lower failure rates
compared to the other two groups.
Conclusion: AMR sign is an S-shaped fold at the inner, free
edge of medial meniscus, formed after an adequate repair of
isolated medial meniscus tear, as viewed on arthroscopy. It is
an objective sign denoting regained integrity of the collagen
architecture of the medial meniscus following repair. It is
also a reliable indicator of excellent long term functional,
clinical, and radiological outcome and also lower failure
rates in patients after arthroscopic medial meniscus repair.
