Long-Term Follow-Up Study of Liver-Related Outcome After Bilio-Pancreatic Diversion in Patients with Initial, Significant Liver Damage

Obesity Management of Liver Transplant Waitlist Candidates and Recipients

Obesity is increasing in prevalence in liver transplant candidates and recipients. The rise in liver transplantation for nonalcoholic steatohepatitis reflects this increase. Management of obesity in liver transplant candidates can be challenging due to the presence of decompensated cirrhosis and sarcopenia. Obesity may increase peritransplant morbidity but does not have an impact on long-term post-transplant survival. Bariatric surgery may be a feasible option in select patients before, during, or after liver transplantation. Use of weight loss drugs and/or endoscopic therapies for obesity management ultimately may play a role in liver transplant patients, but more research is needed to determine safety.

Liver transplantation for bariatric surgery-related liver failure: a systematic review of a rare condition

BACKGROUND

Protein malnutrition and bacterial overgrowth occurring after bariatric surgery (BS) might cause severe liver failure (LF) needing liver transplantation (LT).

OBJECTIVES

To evaluate indications and outcomes of LT for BS-related LF.

SETTING

University hospital in France.

METHODS

The EMBASE, MEDLINE, and COCHRANE central databases were systematically searched according to the PRISMA criteria from inception up through December 2017 for articles describing LT for LF after BS.

RESULTS

Fourteen studies reporting 36 patients listed for LT, of which 32 underwent the procedure, were retained. The types of previously performed BS included jejunoileal bypass (n = 16), bilio-pancreatic diversion according to Scopinaro (n = 14) or with duodenal switch (n = 3), bilio-intestinal bypass (n = 1), long-limb Roux-en-Y gastric bypass (n = 1), and single anastomosis omega gastric bypass (n = 1). Liver failure developed a median of 20 months after BS (mean ± SD: 105 ± 121 mo; range, 5-300 mo). This interval of time was significantly shorter after biliopancreatic diversion than jejunoileal bypass (mean ± SD: 22 ± 21 mo versus 269 ± 27 mo; P = .0001). Four patients (11.1%) died while on the waiting list for LT, and 4 more (12.5%) died after LT. Morbidity and liver retransplantation were reported in 8 (25%) and 2 (6.2%) patients, respectively. Twenty-one patients (65.6%) had their BS procedure reversed (1 patient before, 15 patients during, and 5 patients after LT, respectively). Biopsy-proven steatosis recurrence after LT was reported in 6 patients (18.7%), 4 of whom did not have BS reversal.

CONCLUSIONS

Severe LF occurring after BS, although rare, might require LT. When indicated, LT is effective at restoring liver function, even when BS reversal is performed synchronously.
