Complications of bariatric surgery in transplant patients

Organ transplanted	Study (first author, year of publication, and reference)	Type of bariatric surgery	Number of patients	Risks after transplantation
Liver	Heimbach 2013[30]	Sleeve gastrectomy	7	Gastric staple line leak, EWL
	Lin 2013[25]	Sleeve gastrectomy	9	Superficial wound infections, staple line leak, postoperative bleed requiring blood transfusion, transient encephalopathy, and temporary renal insufficiency
	Lin 2013[34]	Sleeve gastrectomy	9	Mesh dehiscence after a synchronous incisional hernia repair, bile leak from the liver surface requiring laparoscopic drainage, and postoperative dysphagia that required reoperation
	Ayloo 2015[20]	Not mentioned	Narrative review	Elevate risk of anastomotic or staple lines dehiscence or wound complications in bariatric surgery because of steroid therapy
	Tsamalaidze 2018[36]	LSG	12	Risk of complications (infections and leaks) due to immunosuppressive therapies. May potentially alter the absorption of the immunosuppressive medications
Liver and kidney	Dziodzio 2017[27]	Not mentioned	Narrative review	Bile leakage, early reoperation due to dysphagia, and bleeding
Kidney	Modanlou 2009[47]	Not mentioned	188	Cardiac and infectious complications
	Golomb 2014[18]	Sleeve gastrectomy	10	Acute renal failure and sleeve stricture
Heart and kidney	Rex 1991[39]	Vertical banded gastroplasty	1	Inadvertent laceration of the body of the pancreas during the dissection of dense retro gastric adhesions. Subsequently, developed a pancreatic pseudocyst which required percutaneous and then surgical drainage
LVAD	Greene 2017[40]	Sleeve gastrectomy	3	Reflux>30 days (so endoscopic balloon dilatation of a midsleeve was performed)

EWL=Excess weight loss; LSG=Laparoscopic sleeve gastrectomy; LVAD=Left ventricular assist device
