Endoscopic versus laparoscopic drainage of pseudocyst and walled-off necrosis following acute pancreatitis: a randomized trial.

BACKGROUND: Pancreatic fluid collections (PFC) may develop following acute pancreatitis (AP). Endoscopic and laparoscopic internal drainage are accepted modalities for drainage of PFCs but have not been compared in a randomized trial. Our objective was to compare endoscopic and laparoscopic internal drainage of pseudocyst/walled-off necrosis following AP. PATIENTS AND METHODS: Patients with symptomatic pseudocysts or walled-off necrosis suitable for laparoscopic and endoscopic transmural internal drainage were randomized to either modality in a randomized controlled trial. Endoscopic drainage comprised of per-oral transluminal cystogastrostomy. Additionally, endoscopic lavage and necrosectomy were done following a step-up approach for infected collections. Surgical laparoscopic cystogastrostomy was done for drainage, lavage, and necrosectomy. Primary outcome was resolution of PFCs by the intended modality and secondary outcome was complications. RESULTS: Sixty patients were randomized, 30 each to laparoscopic and endoscopic drainage. Both groups were comparable for baseline characteristics. The initial success rate was 83.3% in the laparoscopic and 76.6% in the endoscopic group (p = 0.7) after the index intervention. The overall success rate of 93.3% (28/30) and 90% (27/30) in the laparoscopic and endoscopic groups respectively was also similar (p = 1.0). Two patients in the laparoscopic group required endoscopic cystogastrostomy for persistent collections. Similarly, two patients in the endoscopic group required laparoscopic drainage. Postoperative complications were comparable between the groups except for higher post-procedure infection in the endoscopic group (19 vs. 9; p = 0.01) requiring endoscopic re-intervention. CONCLUSIONS: Endoscopic and laparoscopic techniques have similar efficacy for internal drainage of suitable pancreatic fluid collections with < 30% debris. The choice of procedure should depend on available expertise and patient preference.

Long-Term Disease Course and Pregnancy Outcomes in Women with Inflammatory Bowel Disease: An Indian Cohort Study.

BACKGROUND: The literature on interaction between pregnancy and inflammatory bowel disease (IBD) is inconsistent, and there are no reports on this aspect from Asia. This study evaluated the impact both IBD and pregnancy have on each other in a large cohort of Indian patients. METHODS: In total, 514 females with ulcerative colitis (UC) or Crohn's disease (CD) aged between 18 and 45 years attending IBD clinic, at our institute, from July 2004 to July 2013 were screened, and patients with data on pregnancy status were included (n = 406). Pregnancies were categorized as either before, after or coinciding with disease onset. Long-term disease course was ascertained from prospectively maintained records. Pregnancy and fetal outcomes were recorded from antenatal records or individual interviews. RESULTS: Of 406 patients (UC: 336, CD: 70), 310 became pregnant (UC: 256, CD: 54), with a total of 597 pregnancies (UC: 524, CD: 73). More UC patients with pregnancies were in long-term remission than non-pregnant patients (56.7 vs. 43.4 %, p = 0.04). Long-term remission was less frequent in UC patients in whom pregnancy coincided with disease onset than patients with pregnancies before and after/pregnancy after the disease onset (41.4 vs. 62.5 %, p = 0.023). Pregnancies after the disease onset were associated with more cesarean sections and adverse fetal outcomes than pregnancies before disease onset in both UC and CD patients. CONCLUSIONS: Long-term disease course in UC patients was better in pregnant as compared to non-pregnant patients. Among pregnant UC patients, disease course was worst when pregnancy coincided with disease onset. Pregnancy and fetal outcomes were worse in pregnancy after disease onset than pregnancy before disease onset.

Reduction in mortality in severe acute pancreatitis: A time trend analysis over 16 years.

BACKGROUND: The trend in the outcome of patients with acute pancreatitis (AP) as a result of evolving management practices is not known. OBJECTIVE: To study and compare the outcomes of patients with AP at a tertiary care academic center over a period of 16 years. METHODS: In a retrospective study on a prospectively acquired database of patients with AP, we analyzed time trends of severity and mortality of AP. The influence of determinants of severity [APACHE II score, organ failure (OF), infected pancreatic necrosis (IPN)], and management strategy on the actual and predicted mortality was assessed. The actual mortality was adjusted for severity to analyze the severity-adjusted mortality at different times as a reflection of management practices over time. RESULTS: A total of 1333 patients were studied. The number of patients hospitalized with AP has been increasing over time. The proportion of patients with severe AP also increased from 1997 to 2013 as shown by increasing incidence of organ failure and IPN (Spearman's rank correlation coefficient (ρ): OF ρ(17) = 0.797, p < 0.01; IPN ρ(17) = 0.739, p < 0.001), indicating an increasing referral of sicker patients. Consequently, the overall mortality has been increasing (ρ(17) = 0.584; p = 0.014). However, despite increasing severity of AP, the mortality adjusted for OF has decreased significantly (ρ(17) = -0.55, p = 0.02). CONCLUSION: Even with increasing proportion of patients with severe AP, there has been a significant decrease in organ failure adjusted mortality due to AP suggesting improved management over years.

Primary hepatic lymphoma.

Primary hepatic lymphoma (PHL) is a lymphoproliferative disorder confined to the liver without evidence of involvement of spleen, lymph nodes, bone marrow or other lymphoid structures. This is in contrast to Non Hodgkin's Lymphoma (NHL) that often involves the liver as a secondary manifestation. PHL is a rare disease and constitutes 0.016% of all cases of NHL. PHL typically occurs in middle aged men, and usually the chief presenting symptoms are non specific which includes right upper quadrant pain, B symptoms like fever and weight loss and constitutional symptoms. Most frequent physical finding is hepatomegaly which occurs in 75% of patients. Jaundice is rare and present only in less than 5% of patients. Majority of PHL originates from B cells. The blood investigations and imaging findings are nonspecific. Histopathology is essential and confirms the diagnosis. Treatment modalities include combination of surgical resection, chemotherapy and radiotherapy. The prognosis without therapy is grim. The prognosis and management of PHL is different from hepatocellular carcinoma or metastatic disease, hence it is essential to differentiate it from these diseases. The purpose of this review is to emphasize the importance of accurate diagnosis before implementing therapeutic plan for any hepatic space occupying lesion in liver.

Primary and Secondary Organ Failures Cause Mortality Differentially in Acute Pancreatitis and Should be Distinguished.

OBJECTIVE: The aim of this study was to study the development of early and late organ failure (OF) and their differential impact on mortality in patients with acute pancreatitis (AP). METHODS: Consecutive patients (N = 805) with acute pancreatitis were included in an observational study. Organ failure was categorized as primary if it occurred early due to pancreatitis per se and secondary if it occurred late due to infected pancreatic necrosis (IPN). Primary outcome was a relative contribution of primary OF, secondary OF, and IPN to mortality. RESULTS: Of the 614 patients (mean age, 38.8; standard deviation, 14.6 years; 430 males) in a derivation cohort, 274 (44.6%) developed OF, with 177 having primary OF and 97 secondary OF due to sepsis. Primary OF caused early mortality in 15.8% and was a risk factor for IPN in 76% of patients. Mortality in patients with primary OF and IPN was 49.5% versus 36% in those with IPN and secondary OF (P = 0.06) and 4% in those with IPN but without OF (P < 0.001). The results of the 191 patients in the validation cohort confirmed the relative contribution of primary and secondary OF to mortality. CONCLUSION: Primary and secondary OF contributed to mortality independently and are distinct in their timing, window of opportunity for intervention, and prognosis.
