Totally laparoscopic resection and extraction of specimens via transanal route in synchronous colon and gastric cancer.

INTRODUCTION: Synchronous colon and gastric cancer is a rare clinical entity. In the present case, it is aimed to show that in a patient with synchronous colon and gastric cancer, laparoscopic resection can be safely performed and both specimens can be delivered through a natural orifice. In our knowledge, this is the first example showing the delivery of the gastric resection specimen through the anus in a human being. CASE REPORT: Sixty-six years old male patient with an upper gastrointestinal bleeding and obstruction symptoms was admitted to our department and the evaluation revealed an advanced stage gastric and a synchronous colon cancer. A laparoscopic palliative subtotal gastrectomy with a subtotal colectomy was performed. All anastomoses were performed intracorporeally and colectomy and subtotal gastrectomy specimens were successfully delivered via trans-anal route without any difficulty. Despite major abdominal organ resections, the patients required quite less analgesics in the postoperative period. DISCUSSION: Specimen extraction through the natural orifices eliminates the need and problems of performing additional abdominal incisions to the patients which also leads to reduced postoperative pain. Synchronous surgical procedures do not prevent the natural orifice surgery.

Success rate of natural orifice specimen extraction after laparoscopic colorectal resections.

PURPOSE: To date, no data have been available to inform which cases are appropriate for natural orifice specimen extraction (NOSE) after laparoscopic colorectal resections (LCRRs). Our aim was to evaluate the success rate and the factors affecting the failure in patients who were scheduled for NOSE after LCRRs. METHODS: Seventy-two consecutive cases that were intended for NOSE after LCRR were enrolled. The transanal route was always chosen as the first option, and when it failed, the transvaginal route was tried in female patients. If both failed, the specimen was judged as unsuitable for NOSE and removed through an abdominal wall incision. Demographic data, surgical indications, resection localization, implemented procedures, incision sites, specimen extraction methods, specimen sizes, and failures of NOSE were recorded. RESULTS: A total of 349 colorectal resections (240 open and 109 laparoscopic) in a 3-year period were examined. The subset of 72 consecutive patients who met the criteria were analyzed. Five cases required a conversion to open surgery during resections. In the remaining 67 patients, NOSE after LCRR was successful in 49 cases (73.1%) but failed in 18 (26.9%). Specimens were extracted from transanal and transvaginal routes in 37 (75.5%) and 12 (24.5%) patients, respectively. The failure rate of NOSE after LCRR was higher in males, in colonic lesions, and in large-sized tumors. The mean sizes of transanal and transvaginal extracted specimens were 3.5 ± 3.1 and 5.4 ± 1.4 cm, respectively (p < 0.05). The mean size of the tumors in the failed cases was 6.5 ± 4.2 cm (p < 0.05). CONCLUSIONS: Approximately 2/3 of the unselected LCRRs were suitable for NOSE. The success rate increased with female gender, small-sized tumors, and rectal resections.

Laparoscopic right colectomy with transvaginal extraction in a patient with prior pancreaticoduodenectomy.

INTRODUCTION: Previous complicated abdominal surgeries such as pancreaticoduodenectomy with large abdominal incisions may keep the surgeons away from major laparoscopic procedures. To the best of our knowledge, there is no published study that shows the feasibility of major laparoscopic surgery in a patient with previous pancreaticoduodenectomy. CASE REPORT: A 68-year-old female (BMI 27 kg/m2, ASA II), was admitted for anemia. Her medical history included an open pancreaticoduodenectomy four years ago for chronic pancreatitis. She had an abdominal Mercedes incision. Computed tomography and colonoscopy showed a 5-cm cecal mass with a histological diagnosis of adenocarcinoma. We performed a totally laparoscopic right hemicolectomy and intracorporeal ileotransverse anastomosis. The specimen was extracted through the vagina. The operating time was 500 minutes and the blood loss was 400 ml. The patient was uneventfully discharged on postoperative day four. CONCLUSIONS: Laparoscopic colon surgery can be feasible and safe despite previous extensive abdominal surgeries such as pancreaticoduodenectomy. Moreover, laparoscopic surgery in these cases can also be completed with intracorporeal anastomosis and specimen extraction through a natural orifice.

Treatment of pilonidal disease by combination of pit excision and phenol application.

AIM: To examine the results of our minimal invasive treatment for pilonidal disease. METHODS: Total 83 patients treated by pit excision and consecutive phenol applications on an outpatient setting. All procedures were performed under local anesthesia, without any preoperative testing, colon cleansing, prophylactic antibiotics or sedation. A pit excision (mean length 1.3 ± 0.5 cm) including several close midline orifices was done. Separated pit excisions were done to the remaining midline and lateral orifices. Sinus cavity was cleared of hair and debris, and the walls of the cavity were sclerosed using a cotton bud dipped in 80% liquid phenol. Phenolization was repeated twice on day one and seven. RESULTS: Mean procedure time was 22.2 ± 7.4 min. Rates of patients who did not required analgesics at first, second, third and fourth days after surgery were 58, 85, 91 and 100%, respectively. All the patients returned to work/school after 3 days. Mean wound closure time was 28.5 ± 14.9 days. Total 86.7% of the patients were asymptomatic after a mean 25.7 ± 8.5 months follow-up. CONCLUSION: Simple pit excision and sclerosing the pilonidal sinus cavity consecutively was an effective and minimal invasive method for relief of pilonidal symptoms.

Tramadol or paracetamol do not effect the diagnostic accuracy of acute abdominal pain with significant pain relief - a prospective, randomized, placebo controlled double blind study.

OBJECTIVES: To examine the effects of early administration of analgesics in patients with acute abdominal pain on pain severity, abdominal findings and diagnostic accuracy. METHODS: 210 patients with non-traumatic acute abdominal pain lasting less than 72 hours were enrolled to this trial. Patients were administrated by placebo, tramadol (1 mg/kg), or paracetamol (15 mg/kg) randomly after the first evaluation of pain severity scores (standard 100 mm visual analog scale) and abdominal findings (rebound, rigidity, tenderness). After 20 and 40 minutes of administrations, pain severity scores and abdominal findings were re-examined. Complete blood count, electrocardiography, plain abdominal x-ray, urine analysis and abdominal ultrasound were used for the initial diagnosis. The final diagnoses were decided after re-examinations, biochemical blood analysis, abdominal computed tomography in all patients and consultations or other diagnostic methods when necessary. RESULTS: There were 70 patients in each group. Baseline pain severity scores and abdominal findings were similar at all groups. After 20 minutes, pain severity scores were decreased in tramadol and paracetamol groups compared with the placebo group as 55% and 45% vs 1% respectively (p < 0.001). After 40 minutes, decreases on pain severity scores were more significant at treatment groups, 67% and 60% vs 0 (p < 0.001). When compared to placebo tramadol and paracetamol increased the new onset or worsening nausea or vomiting. There was no difference on abdominal findings among the groups after 20 and 40 minutes examinations. Diagnostic accuracy of tramadol, paracetamol and placebo groups were 96%, 94% and 94% respectively. CONCLUSIONS: Early administration of tramadol and paracetamol provided effective pain relief in patients with non-traumatic acute abdominal pain and those administrations did not interfere with diagnosis.

Does laparoscopic-guided transversus abdominis plane block have an effect on postoperative pain and recovery after sleeve gastrectomy?

OBJECTIVE: Postoperative pain management is thought to have an effect on patient comfort, morbidity, and mortality after bariatric surgery. Local anesthetic agents are frequently used for this purpose. Local anesthetics can be used in many different ways. In this study, we aimed to investigate the effect of transversus abdominis plane (TAP) block on postoperative pain by laparoscopic method. PATIENTS AND METHODS: A prospective randomized clinical trial was performed. While TAP block was applied to one group with bupivacaine, no action was taken for the other group. Postoperative analgesia was given to both patient groups with the "patient-controlled analgesia (PCA)" device. Demographic, operational, and postoperative clinical and pain data of the patients were recorded. RESULTS: TAP block and non-TAP block groups consisted of 30 patients each. Visual analog scale (VAS) scores of the patients at 6, 12, and 24 hours were lower in the TAP group compared to the non-TAP group (p=0.015, 0.018, 0.04, respectively). According to the PCA device data, the analgesic requirement was lower in the TAP group at 6, 12, and 24 hours (p <0.001). Rescue analgesia was required more in the non-TAP group (p=0.04). There was no statistically significant difference between the two groups in terms of gas discharge time (p=0.102), stool discharge occurred earlier in the TAP group (p=0.02). Oral intake times (p=0.554) and length of stay hospital (p=0.551) were similar. CONCLUSIONS: Laparoscopic TAP block using bupivacaine can be safely administered in morbidly obese patients and reduces postoperative analgesic requirements. Thus, side effects that may develop secondary to the use of analgesics are avoided.

Preoperative staging of colon cancer patients: ultrasound can be a valuable alternative to computed tomography.

OBJECTIVE: The aim of this study was to compare the results of ultrasound and CT assessment in preoperative staging of colonic cancer, and to determine whether CT offers any benefits beyond ultrasound. PATIENTS AND METHODS: Sixty-one cases of intraperitoneal colon cancer were assessed by preoperative abdominal ultrasound and CT. The ultrasound and CT findings were assessed for ascites, hepatic and peritoneal metastases, invasion of adjacent organs, and findings of other diseases. RESULTS: The sensitivity rates of CT for liver metastases, adjacent organ invasion, ascites and peritoneal metastases were 81 %, 25 %, 29 % and 20 % respectively, while those of ultrasound were 69 %, 6 %, 43 % and 0%, respectively. Both methods had similar sensitivity, specificity and accuracy rates regarding the detection of all criteria. Ultrasound was more sensitive for detecting ascites and liver metastasis when compared to peritoneal metastasis and invasion (p<0.05). CT allowed the detection of liver metastasis to be more sensitive when compared to the other three criteria (p<0.05). In addition to ultrasound, CT gave no more additional knowledge indicating the necessity of altering the clinical management in patients. CONCLUSION: The first-line scanning technique should be the ultrasound and there is no need for CT scan, should no abnormalities be found upon ultrasound examination. CT investigation plays a role in cases where the ultrasound findings are suspicious (Tab. 1, Ref. 16). Full Text in free PDF www.bmj.sk.

Surgical treatment of phytobezoars causes acute small intestinal obstruction.

PURPOSE: Our aim was to perform a clinical analysis of small intestinal obstructions caused by surgically treated phytobezoars. METHODS: Twenty-four patients, with small intestinal obstructions caused by phytobezoars, underwent surgery in our department between 1998 to 2008, were reviewed retrospectively. RESULTS: Twenty (83.3%) of 24 patients had previous gastric surgery. Preoperative computed tomography (CT) was performed in nine patients and seven (77.8%) patients, showed results consistent with a bezoar and subsequently, underwent surgery on the same day. The remaining patients had no preoperative diagnosis of a phytobezoar were typically followed-up for postoperative adhesion intestinal obstruction. Only those patients who showed no response to nonoperative treatment options underwent surgery. The phytobezoar was fragmented and milked into the cecum in 11 (45.8%) patients or extracted via longitudinal enterotomy in 12 (50%) patients; the remaining patient (4.2%) was treated via laparoscopy. Three patients had gastric phytobezoars, which were extracted via gastrotomy. There was no postoperative mortality. Two patients with previous enterotomy had either postoperative wound infection or wound infection and evisceration. CONCLUSIONS: Phytobezoars should be considered in the differential diagnosis of acute small intestinal obstruction in patients with prior gastric surgery, poor dentition, or consume fiber-rich foods. Abdominal CT is useful for both diagnosis and for the decision to perform emergency surgery. When possible, the phytobezoar should be fragmented and milked into the cecum. Laparoscopic fragmentation may be useful in such cases (Tab. 3, Ref. 28). Full Text (Free, PDF) www.bmj.sk.

Living Donor Re-transplantation for Repeated Acute Liver Failure.

Emergency liver transplantation (LT) for acute liver failure (ALF) is a life-saving treatment. Occurrence of this situation in the same patient twice is very rare. Herein, we describe a patient who underwent two emergency LTs for ALF, both from living donors. When she was 26 years old, she underwent a right lobe living donor LT (LDLT) from her sister for ALF due to use of herbal weight loss medications. The next 3 years were uneventful but another ALF developed during a terminal stage pregnancy (37th week). Despite medical treatment, her liver functions worsened, and the baby was delivered by caesarean section. The second time, her brother was the donor and she recovered after the emergency right lobe re-LDLT. Both patient and baby were well at the 2-month follow-up. As far as we know, there is no reported similar case, and we concluded that LDLT is a paramount treatment option for both primary and secondary ALFs.

Telescopic Biliary Reconstruction in Patients Undergoing Liver Transplantation With 1-Year Follow-up.

BACKGROUND: Biliary complications are important during liver transplantation because of their effect on recipient and graft survival, incidence, and the long treatment period. These complications are associated with 50% morbidity and 30% mortality rates in recent studies. One of the most important reasons for biliary anastomosis complications is arterial ischemia. We present the results of our telescopic biliary anastomosis technique performed on the mucosa of the main biliary duct. PATIENTS AND METHODS: Fifty-six cases of telescopic biliary reconstruction were performed in 203 patients during 2015. Fifty cases and 52 patients who underwent standard reconstruction were chosen and compared. All patients had been scanned retrospectively. Statistical analyses were conducted with χ2 and Mann-Whitney U tests for the complications that occurred during the first 3 months. A P value <.05 was considered significant. RESULTS: No clinical or demographic differences were detected between the groups. About 90% of both groups were living donor liver transplantation cases. Five (10%) anastomotic leaks occurred in telescopic reconstruction group (n = 50), and 13 (25%) occurred in the standard reconstruction group (n = 52; P < .05). CONCLUSION: The arterial blood supply is better if the biliary anastomosis is made on the mucosal side of the main biliary duct. Early period anastomotic leaks may decrease significantly.

Can Patients Who Develop Cerebral Death in Fulminant Liver Failure Despite Liver Transplantation Be Previously Forseen?

BACKGROUND: The outcome of medical treatment is worse in fulminant liver failure (FLF) developing on acute or chronic ground. Recently, liver transplantations with the use of living and cadaveric donors have been performed in these diseases and good results obtained. In this study, we aimed to present the factors affecting the recovery of cerebral functions after liver transplantation in hepatic encephalopathy (HE) developing in FLF, to identify irreversible patient groups and to prevent unnecessary liver transplantation. METHODS: In Inonu University's Liver Transplant Institute, 69 patients who made an emergency notice to the National Coordination Center for liver transplantation owing to FLF from January 2012 to December 2015 were included in the study. Patients were divided into 2 groups. Group 1 consisted of 52 patients who underwent liver transplantation and recovered normal brain function, and group 2 had 17 patients who underwent liver transplantation and did not recover normal brain function and had cerebral death. All patients were evaluated before surgery for clinical encephalopathy stage, light reflex, and convulsions. Groups were compared and assessed according to age (>40, 10-40 and <10 years), body mass index, etiologic factor, preoperative laboratory values, transplantation type, mortality, and encephalopathy level. Multivariate analysis was done for specific parameters. RESULTS: Prothrombin time (PT), international normalized ratio (INR), and total bilirubin values were significantly different between the groups. There was no significant difference between the groups regarding ammonia and lactate levels. There was a statistically significant difference between the groups regarding sodium and potassium levels from serum electrolytes. However, the averages of both groups were within normal limits. pH and total bilirubin levels were meaningful for multivariate analysis. CONCLUSIONS: HE reversibility, mortality, and morbidity are important in patients with HE who undergo liver transplantation. Therefore, West Haven clinical staging and serum INR, PT, and total bilirubin level may be helpful in predicting the reversibility of FLF patients with HE before liver transplantation. It was determined that West Haven encephalopathy grading is important in determining the reversibility of HE after transplantation in FLF; especially the probability of reversibility of stage 4 HE decreases significantly. High PT and INR levels, hyperbilirubinemia, and serum sodium and potassium concentrations were risk factors for the reversibility of HE in this study.

Effects of nucleoside analogues on liver regeneration 70% partially hepatectomized rats.

The alternatives for prophlaxis and treatment of recurrent hepatitis B virus infection have increased since new oral nucleoside analogues have become available. We conducted this experimental study to investigate the effect in the liver of these agents on the expression of transforming growth factor alpha (TGF-alpha) and on proliferation index, estimated by Ki-67. Thirty male Wistar albino rats were randomized into three groups: group A (n = 10) received adefovir dipivoxil (40 mg/kg/d per gavage); group B (n = 10), lamivudine (L; 30 mg/kg/d per gavage); and group C (n = 10) did not receive any treatment and were the control group. Groups A and B were treated for 3 days. Animal treatment began on day -1. After performing 70% partial hepatectomy on day 0, all rats were sacrificed on postoperative day 2 to harvest liver tissues for histopathological examination. We stained and indexed Ki-67 and TGF-alpha immunohistochemically on the hepatectomy surface and in the parenchyma, Ki-67 and TGF-alpha indices were significantly higher in group A compared with group B (P = .001 and P = .004, respectively, and P = .003 and P = .001, respectively). When the L group was compared with the control group for results on the hepatectomy surface and the parenchyma, Ki-67 and TGF-alpha indexes were insignificantly different (P = .6 and P = .3, respectively, and P = .1 and P = .6, respectively). Based on the results of this experimental study, we concluded that Adefovir dipivoxil has greater proliferative effect on liver parenchyma and in the cut surface than does lamivudine.

Using autologous peritoneal graft for portal vein injury due to blunt thoracoabdominal trauma.

BACKGROUND: Autologous vein or prosthetic materials are used as patch or tube graft for portal or caval vein reconstruction after trauma or tumor resection. Preparation of autologous veins requires extra incisions and is time consuming that is crucial especially in trauma patients. This condition adversely affects postoperative morbidity and mortality, particularly in trauma cases. Prosthetic materials may not be available in some centers, and their use is associated with an increased risk of infection. DESCRIPTION OF CASE: A 28-year-old hemodynamically unstable man presented to the emergency room with complete transection of main portal vein, right hepatic artery and common bile duct with tissue defect on hepatoduodenal ligament due to blunt thoracoabdominal trauma. Reconstructing of the portal vein was performed using an autologous peritoneal tube graft. CONCLUSION: Autologous peritoneal graft is a very good option in the treatment of major vascular injuries which can not be repaired with primary suturing. It is also easy to prepare and use, safe, without a need of additional incision, as an alternative to autologous veins and prosthetic materials especially under emergency conditions.

Retained Foreign Body in Transplanted Liver.

Liver transplantation is a technically complex and long surgical procedure. A large quantity of various materials such as catheters, sutures, needles and clips are frequently used during the procedure. These materials may enter in the liver from the vascular or biliary orifices inadvertently. A 50-year-old patient who had hepatic failure due to HBV underwent a deceased-donor liver transplantation. The deceased donor was a 75-year-old HbsAg(+) man. The recipient had subfebrile fever and leukocytosis post-operatively. A control computed tomography revealed a cuneiform ischemic area, and a foreign body inside the right anterior portal vein branch proximal to this ischemic region. A 10-F Nelaton catheter, 5-cm long, was removed from the portal vein by surgery. Retrospectively, we understood that the portal vein was cut during the back-table procedure and the portal vein catheter was replaced with a larger one for better irrigation. Most probably, the original catheter was cut together with the portal vein, and the tip of the catheter was retained in the portal system and migrated into the liver. As far as we know, such a complication of liver transplantation has never been described previously.

Circumferential Fence With the Use of Polyethylene Terephthalate (Dacron) Vascular Graft for All-in-One Hepatic Venous Reconstruction in Right-Lobe Living-Donor Liver Transplantation.

Integration of hepatic vein tributaries with a diameter ≥ 5 mm into the drainage system in right-lobe living-donor liver transplantation (LDLT) is of vital importance for graft function. Recently, the most commonly emphasized hepatic venous reconstruction model is the all-in-one reconstruction model. In the final stage of this model that aims to form a common large opening, allogeneic vascular grafts are almost always used to construct a circumferential fence. To date, no other study has reported the use of polyethylene terephthalate (Dacron) vascular graft as a circumferential fence in LDLT. We aimed to present the 1st 4 cases of circumferential fences created with Dacron vascular graft. Four right-lobe grafts weighing 522-1,040 g were used. A polytetrafluoroethylene vascular graft was used for the integration of segment 5 vein and segment 8 vein into the drainage model, whereas a Dacron graft was used to creating a circumferential fence. The patency of hepatic outflow evaluated with the use of multidetector computerized tomography at postoperative day 7. Venous outflow obstruction was not detected in any cases. This study suggested that owing to its flexible structure the polyethylene terephthalate vascular graft can be an alternative to allogeneic vascular grafts in forming circumferential fence.

Futility Versus Acceptability of the Use of Grafts Taken From End of Line in the National Organ-Sharing Network.

BACKGROUND: The number of suitable donors for organ transplantation is limited in many countries. This limitation can be overcome with the use of organs removed from marginal donors (expanded-criteria donors [ECDs]). We examined the long-term results of 187 patients who underwent marginal cadaveric liver transplantation in our institution. METHODS: The data of patients who underwent cadaveric liver transplantation from January 2007 to April 2014 were retrospectively reviewed. ECDs were evaluated by considering 19 internationally accepted criteria. The clinical data of recipients including age, clinical status, and Model for End-Stage Liver Disease (MELD) score were also assessed. RESULTS: A total of 287 patients underwent cadaveric liver transplantation. A graft from an ECD was used in 181 (63.06%) patients. The mean MELD score was 18.8. In all, 45 patients (24.86%) underwent transplantations for fulminant liver failure and 136 patients (75.14%) underwent transplantations for other chronic conditions. The majority of donors died of cerebrovascular disease and trauma. Only hypotension requiring inotropic drugs and obesity significantly affected survival. The 90-day and 12-month survival rates of the recipients who received a graft from an ECD were 51.93% and 46.2%, respectively. CONCLUSIONS: The use of ECD allografts immediately and significantly expands the existing donor pool. Because of persistent organ scarcity, pressure to use a greater proportion of the existing donor pool will continue to increase.

Histopathological Examination of Explanted Liver After Transplantation in Patients With Cryptogenic Cirrhosis.

OBJECTIVES: Cryptogenic cirrhosis is a common indication for liver transplantation. Diagnosis is made after exclusion of other causes of cirrhosis. In this study, the aim was to evaluate patients with cryptogenic cirrhosis after histopathological examination of explanted liver. MATERIALS AND METHODS: A retrospective histopathological chart review of 117 patients with cryptogenic cirrhosis who had liver transplantation between November 2009 and June 2014 was performed. Age, sex, operative features, survival rates, and preoperative and postoperative diagnosis were evaluated. RESULTS: During the study period, 123 liver transplantations were performed for these 117 patients. Deceased donor liver transplantations were performed in 23 (18.7%) of the cases. Retransplantations were performed in 5 patients. Median age was 48 years, and female-to-male ratio was 41:76. Hepatosteatosis were observed in 29 patients. Nonalcoholic fatty liver disease and nonalcoholic steatohepatitis were observed in 20 (12%) and 9 (7.7%) of these patients, respectively. Autoimmune hepatitis was observed in 2 patients. The definitive cause of cirrhosis was unclear in 68 (58%) of the patients. Incidental malignant and premalignant lesions were observed in 15 patients. CONCLUSIONS: Histopathological examination of the explanted liver after liver transplantation in those patients with cryptogenic cirrhosis may significantly help to diagnose the cause of cirrhosis, such as nonalcoholic steatohepatitis or autoimmune hepatitis, with using the scoring system developed by the International Autoimmune Hepatitis Workgroup. In addition, incidental malignant or premalignant lesions may be observed.

Living Donor Liver Transplantation With Vena Cava Replacement.

OBJECTIVES: This study sought to evaluate the indications, techniques, and results of inferior vena cava (IVC) replacement at living donor liver transplantation (LDLT). MATERIALS AND METHODS: We performed 821 LDLTs and 11 (1.3%) patients required concomitant IVC replacement. We analyzed the indications, replacement materials, and outcomes. RESULTS: Right, left, and left lateral liver lobes were transplanted in 7, 2, and 2 patients, respectively. The indications for IVC replacement were thrombosis/fibrosis in 7 patients (Budd-Chiari 4, hereditary tyrosinemia 1, congenital hepatic fibrosis 1, cryptogenic 1), involvement with mass in 3 patients (Echinococcus alveolaris 2, hepatoblastoma 1) and iatrogenic narrowing at IVC in 1 patient. Cryopreserved grafts (aorta n = 5, IVC n = 4, iliac vein n = 1) or synthetic graft (n = 1) were used for replacements. In 1 patient, hepatic outflow obstruction developed at 39 days and was treated successfully by interventional radiology. There was only 1 hospital mortality (8.9%) that was unrelated to caval replacement (subarachnoid hemorrhage). Of the remaining patients, the caval grafts were patent after a mean 7.7 months of follow-up (range 1 to 17 months). CONCLUSIONS: Although rare, IVC replacement can be necessary at LDLT. Budd-Chiari and E. alveolaris are the main underlying diseases for replacement requirements. Caval replacement with cryopreserved vascular grafts can provide successful short-term and long-term patency.
