Management of biliary tract disease in heart and lung transplant patients

Acute abdomen in the immunocompromised patient: WSES, SIS-E, WSIS, AAST, and GAIS guidelines

Immunocompromised patients are a heterogeneous and diffuse category frequently presenting to the emergency department with acute surgical diseases. Diagnosis and treatment in immunocompromised patients are often complex and must be multidisciplinary. Misdiagnosis of an acute surgical disease may be followed by increased morbidity and mortality. Delayed diagnosis and treatment of surgical disease occur; these patients may seek medical assistance late because their symptoms are often ambiguous. Also, they develop unique surgical problems that do not affect the general population. Management of this population must be multidisciplinary.This paper presents the World Society of Emergency Surgery (WSES), Surgical Infection Society Europe (SIS-E), World Surgical Infection Society (WSIS), American Association for the Surgery of Trauma (AAST), and Global Alliance for Infection in Surgery (GAIS) joined guidelines about the management of acute abdomen in immunocompromised patients.

Acute cholecystitis in recent lung transplant patients: a single-institution series of 10 cases

OBJECTIVE

To evaluate the clinical and imaging findings of acute cholecystitis in recent lung transplant patients.

METHODS

We retrospectively reviewed all abdominal ultrasounds and computed tomography (CT) scans of patients who developed acute cholecystitis in the early postoperative period following lung transplantation from November 2014 to December 2020 in a tertiary care university hospital.

RESULTS

Ten patients (4.4%) were included in this series (6 male, mean age 62.9 years ± 2.1 [standard deviation]) of a total 227 lung transplant patients performed from November 2014 to December 2020 (172 unilateral and 55 bilateral). Nine (90%) patients received a double-lung transplant and seven (70%) required extracorporeal circulation during surgery. Acute cholecystitis occurred during the initial admission for lung transplantation (average of 33 ± 25.9 days post-transplantation). Six patients (60%) died during admission with an average of 24.3 ± 21.8 days after cholecystectomy. The most frequent imaging findings were gallbladder wall discontinuity or decreased gallbladder mural enhancement (100%, 10 patients) and gallbladder distension (90%, 9 patients). All acute cholecystitis were found to be ischemic / gangrenous at surgery and/or pathology, 40% (4 patients) were hemorrhagic and 30% (3 patients) were perforated, one of them with a cholecystoduodenal fistula. Fungal cholecystitis was demonstrated at histological exam in one patient.

CONCLUSION

Acute cholecystitis in the early postoperative period after lung transplantation is an important cause of morbidity and mortality. Ischemic or gangrenous cholecystitis prevails. The key imaging findings are parietal perfusion defects and gallbladder distension, which can easily go unnoticed if not specifically looked for.

Emergency abdominal surgery after solid organ transplantation: a systematic review

AIMS

Due to the increasing number of solid organs transplantations, emergency abdominal surgery in transplanted patients is becoming a relevant challenge for the general surgeon. The aim of this systematic review of the literature is to analyze morbidity and mortality of emergency abdominal surgery performed in transplanted patients for graft-unrelated surgical problems.

METHODS

The literature search was performed on online databases with the time limit 1990-2015. Studies describing all types of emergency abdominal surgery in solid organ transplanted patients were retrieved for evaluation.

RESULTS

Thirty-nine case series published between 1996 and 2015 met the inclusion criteria and were selected for the systematic review. Overall, they included 71671 transplanted patients, of which 1761 (2.5 %) underwent emergency abdominal surgery. The transplanted organs were the heart in 65.8 % of patients, the lung in 22.1 %, the kidney in 9.5 %, and the liver in 2.6 %. The mean patients' age at the time of the emergency abdominal surgery was 49.4 ± 7.4 years, and the median time from transplantation to emergency surgery was 2.4 years (range 0.1-20). Indications for emergency abdominal surgery were: gallbladder diseases (80.3 %), gastrointestinal perforations (9.2 %), complicated diverticulitis (6.2 %), small bowel obstructions (2 %), and appendicitis (2 %). The overall mortality was 5.5 % (range 0-17.5 %). The morbidity rate varied from 13.6 % for gallbladder diseases to 32.7 % for complicated diverticulitis. Most of the time, the immunosuppressive therapy was maintained unmodified postoperatively.

CONCLUSIONS

Emergency abdominal surgery in transplanted patients is not a rare event. Although associated with relevant mortality and morbidity, a prompt and appropriate surgery can lead to satisfactory results if performed taking into account the patient's immunosuppression therapy and hemodynamic stability.

Postoperative outcomes with cholecystectomy in lung transplant recipients

INTRODUCTION

There is a paucity of data on outcomes for lung transplant (LT) recipients requiring general surgery procedures. This study examined outcomes after cholecystectomy in LT recipients using a large database.

METHODS

The National Inpatient Sample Database (2005-2010) was queried for all LT patients requiring laparoscopic cholecystectomy (LC) and open cholecystectomy (OC).

RESULTS

There were a total of 377 cholecystectomies performed in LT patients. The majority were done for acute cholecystitis (n = 218; 57%) and were done urgently/emergently (n = 258; 68%). There were a total of 304 (81%) laparoscopic cholecystectomies and 73 (19%) OC. There was no difference in age when comparing the laparoscopic and open groups (53.6 vs 55.5 years; P = .39). In addition, the Charlson Comorbidity Index was similar in the 2 groups (P = .07). Patients undergoing OC were more likely to have perioperative myocardial infarction, pulmonary embolus, or any complication compared with the laparoscopic group. Total hospital charges ($59,137.00 vs $106,329.80; P = .03) and median duration of stay (4.0 vs 8.0 days; P = .02) were both greater with open compared with LC.

CONCLUSION

Cholecystectomy can be performed safely in the LT population with minimal morbidity and mortality.

Abdominal Surgery after Lung Transplantation

Among 450 patients who underwent lung transplantation (LuT) between April 1994 and April 2009 at a single academic hospital, 75 received surgical consultation, and 52 underwent 65 abdominal operations. Operations included colectomy (17), cholecystectomy (14), exploratory laparotomy (10), ulcer repair (five), hernia repair (four), Nissen fundoplication (four), pancreatic debridement (four), ostomy takedown (two), drainage of intra-abdominal abscess (two), and major vascular procedure, gastrostomy, splenectomy, fascial closure, laparoscopic common bile duct exploration, and small bowel resection (one each). Fourteen patients (27%) died within 30 days of surgery. On univariate analysis, age, race, comorbidities, history of previous abdominal surgery, transplant type, and timing of surgery after transplant were similar between the patients who survived and died. On multivariate analysis, emergent surgery, multiple medical comorbidities, and male gender were predictive of 30-day mortality ( P ≤ 0.05). Ulcer repair, major vascular procedures, pancreatic surgery, splenectomy, and exploratory laparotomy were associated with ≥ 50 per cent 30-day mortality. This is the largest series reporting outcomes of abdominal operations after LuT. Elective operations in LuT patients are safe, whereas emergent operations carry an extremely high short-term mortality rate. Aggressive prophylaxis for ulcer disease and early elective intervention for potential surgical problems, such as gallstones and uncomplicated diverticulitis, should be considered.

Cholelithiasis in patients on the kidney transplant waiting list

OBJECTIVES

To evaluate the prevalence of cholecystopathy in chronic renal patients awaiting kidney transplants.

INTRODUCTION

The prevalence and management of cholelithiasis in renal transplant patients is not well established.

METHODS

A total of 342 chronic renal failure patients on the waiting list for a kidney transplant were studied. Patients were evaluated for the presence of cholelithiasis and related symptoms, previous cholecystectomies and other abdominal surgeries, time on dialysis, and general data (gender, age, number of pregnancies, and body mass index).

RESULTS

Cholelithiasis was found in 41 out of 342 patients (12%). Twelve of these patients, all symptomatic, had previously undergone cholecystectomies. Five out of 29 patients who had not undergone surgery were symptomatic. Overall, 17 patients (41.5%) were symptomatic. Their mean age was 54 (range 32-74) years old; 61% were female, and their mean body mass index was 25.4. Nineteen (76%) out of 25 women had previously been pregnant, with an average of 3.6 pregnancies per woman.

CONCLUSIONS

The frequency of cholelithiasis was similar to that reported in the literature for the general population. However, the high frequency of symptomatic patients points toward an indication of routine pre-transplant cholecystectomy to avoid serious post-transplant complications.

Gallstone formation after pancreas and/or kidney transplantation: an analysis of risk factors

Pancreas and kidney transplantation (SPK) is the treatment of choice for patients with type 1 diabetes mellitus and end-stage renal failure. Gallstones are common after SPK transplantation but little is known about the true incidence and etiology of gallstones in this group. We therefore evaluated the incidence of gallstones and the presence of transplant-related risk factors in patients after SPK and kidney transplantation alone (KTA). Data were evaluated of 56 consecutive patients who underwent SPK transplantation and compared the results with those of 91 consecutive nondiabetic patients who underwent KTA transplantation at the Leiden University Medical Center between 1987 and 1994. Of the 58 evaluable KTA patients, 20.7% developed gallstones during 7.7 yr of follow-up and in the SPK group 43.9% of the 41 evaluable patients developed gallstones during 7.1 yr of follow-up. Postoperative weight loss and cyclosporin A-related hepatotoxicity correlated with gallstone formation both in SPK and KTA patients. In addition, the duration of postoperative fasting and autonomic neuropathy correlated with gallstones in SPK patients. It is concluded that both in patients after SPK transplantation and in patients after KTA transplantation, the risk to develop gallstones is significantly increased. Physicians should be aware of the high incidence of gallstones in SPK recipients.

Asymptomatic cholelithiasis: is cholecystectomy really needed? A critical reappraisal 15 years after the introduction of laparoscopic cholecystectomy

Asymptomatic cholelithiasis is increasingly diagnosed today, mainly as a result of the widespread use of abdominal ultrasonography for the evaluation of patients for unrelated or vague abdominal complaints. About 10-20% of people in most western countries have gallstones, and among them 50-70% are asymptomatic at the time of diagnosis. Asymptomatic gallstone disease has a benign natural course; the progression of asymptomatic to symptomatic disease is relatively low, ranging from 10-25%. The majority of patients rarely develop gallstone-related complications without first having at least one episode of biliary pain ("colic"). In the prelaparoscopy era, (open) cholecystectomy was generally performed for symptomatic disease. The minimally invasive laparoscopic cholecystectomy refueled the discussion about the optimal management of asymptomatic cholelithiasis. Despite some controversy, most authors agree that the vast majority of subjects should be managed by observation alone (expectant management). Selective cholecystectomy is indicated in defined subgroups of subjects, with an increased risk for the development of gallstone-related symptoms and complications. Concomitant cholecystectomy is a reasonable option for good-risk patients with asymptomatic cholelithiasis undergoing abdominal surgery for unrelated conditions. Routine cholecystectomy for all subjects with silent gallstones is a too aggressive management option, not indicated for most subjects with asymptomatic cholelithiasis. An in-depth knowledge of the natural history of gallstone disease is required to select the optimal management option for the individual subject with silent gallstones. Management options should be extensively discussed with the patient; he or she should be actively involved in the process of therapeutic decision making.

Gastrointestinal complications following transplantation

Gastrointestinal complications are common after kidney, liver, pancreas, heart, and lung transplantation. Complications can include gastrointestinal conditions preceding the transplantation, viral, fungal, and bacterial gastrointestinal infections, and gastrointestinal side effects of medications including immunosuppressive agents. Establishing the etiology of gastrointestinal complaints is often difficult because any one or a combination of these factors might be contributory in the same patient.

Intraabdominal complications after lung transplantation

BACKGROUND

Because more lung transplant recipients survive the perioperative period, nonpulmonary complications become a major source of morbidity and mortality. Of these, intraabdominal complications are of particular concern because of the potential need for surgical intervention. So appropriate management of these complications becomes paramount.

STUDY DESIGN

We retrospectively reviewed 229 lung transplant recipients in a university medical center, between January 1997 and December 2004 developed in forty-seven patients. Abdominal complications. Detailed reviews of these patients' hospital charts were performed. Complications were categorized as early or late depending on if they occurred within 30 days of transplantation or later. The primary outcomes variable studied was mortality.

RESULTS

Fifty-three surgical consultations for abdominal symptoms were requested in these 47 patients. Twenty-two of the 47 patients (47%) with intraabdominal complications required 24 operative interventions. Overall 5-year survival was substantially worse in patients with intraabdominal complications (34%) than in those without (62%, p=0.01). There was no marked difference in the 30-day mortality for patients experiencing early (27%, 4 of 15) versus late (24%, 9 of 38) complications. Mortality in patients with intraabdominal complications was lower among those treated operatively (n=2, 9%) compared with those treated nonoperatively (n=11, 44%, p=0.02).

CONCLUSIONS

Mortality for patients with intraabdominal complications is high after lung transplantation. Operative intervention is well tolerated and associated with lower mortality. A high index of suspicion and timely operative intervention are necessary for the treatment of intraabdominal complications in lung transplant recipients.

Critical care issues in lung and heart transplantation

Although much has been accomplished in HTx and LTx in the past few decades, much remains to be conquered. It is an ever-changing, always fascinating field. Though science and technology know no limits, the primary limitation of HTx and LTx continues to be the availability of donor organs. One can only hope that further advances in educating the public will help close the large gap between the list of those waiting and the organs available for transplantation.

Gallstone disease in heart transplant recipients

OBJECTIVE

To review the outcome of cholecystectomy after heart transplant.

SUMMARY BACKGROUND DATA

The optimal timing for gallbladder surgery in heart transplant patients is controversial.

METHODS

Between April 1985 and October 2000, 518 cardiac transplants were performed at Ochsner Foundation Hospital. Data gathered included ultrasound reports, cholecystectomy operative reports, gallbladder pathologic reports, complications, and deaths.

RESULTS

Charts were available for 509 patients (98%), 68 (13%) of whom underwent cholecystectomy before transplantation. Of the 509, 53 (10%) had serial ultrasound examinations and 29 of the 53 (55%) developed gallstones. After transplant, 47 (9%) underwent cholecystectomy. Five cholecystectomies were performed during the immediate postoperative course. Two patients who underwent cholecystectomy had acalculous cholecystitis; one was incidental. Four patients died (one with rejection and three with sepsis). After discharge, 42 cholecystectomies were performed: 16 for biliary colic (no deaths, three patients with complications), 19 for acute cholecystitis (one death, nine patients with complications), 5 for biliary pancreatitis (1 death, 1 patient with complications), and 2 others.

CONCLUSIONS

The risk of morbidity and mortality from gallstone disease is high in cardiac transplant patients, particularly immediately posttransplant. Posttransplant patients require annual ultrasound examinations to detect the onset of gallstone disease, and this risk is higher than in the general population. Gallstones alone are an indication for cholecystectomy in the cardiac transplant patient. Pretransplant cholecystectomy should be considered in clinically stable patients with gallstones.

GI complications after lung transplantation in patients with cystic fibrosis

STUDY OBJECTIVE

Lung transplantation is now available for patients with cystic fibrosis (CF) and end-stage lung disease. While pulmonary graft function is often considered the major priority following transplantation, the nonpulmonary complications of this systemic disease also continue. We examined the GI complications in a cohort of patients who underwent transplantation.

DESIGN

This was a retrospective study of all patients with CF who underwent transplantation between March 1988 and December 1998 in Toronto. Medical records were reviewed, and a short questionnaire was mailed to patients who were alive as of December 1998.

RESULTS

There were 80 bilateral lung transplants performed in 75 patients. The questionnaire was distributed to 43 patients, of whom 27 patients (63%) responded. Pancreatic insufficiency requiring enzyme intake was evident in 72 of 75 patients (96%) at the time of surgery. Of three pancreatic-sufficient patients (4%), pancreatic insufficiency was diagnosed in two patients later. Biliary cirrhosis was diagnosed in three patients prior to transplantation. Distal intestinal obstruction syndrome (DIOS) was recorded for 15 patients (20%). Ten patients had a single episode, of which eight episodes occurred early in the postoperative period. Five patients had recurrent episodes. All were medically treated, except for two patients who underwent surgery. Other complications included cholecystitis (n = 3), mucocele of the appendix (n = 1), peptic ulcer disease (n = 3), and colonic carcinoma (n = 1).

CONCLUSION

GI complications after lung transplantation are common in patients with CF, and attention should be paid to the risk for DIOS in the early postoperative period. Prevention and early medical treatment are important in order to avoid acute surgery. Close collaboration with the CF clinic, in order to diagnose and treat CF-related complications, is recommended.
