An Elbow Patch Reconstruction Technique for Narrowed Remnant Portal Veins during Right Lobe Living Donor Hepatectomy: A Rescue Surgery.

Background: Treatment of established portal vein narrowing after living donor hepatectomy is challenging. We aimed to present a new approach termed the "elbow patch reconstruction technique" to correct the narrowed remnant portal vein just or late after right lobe living donor hepatectomy. Methods: Demographic and clinical data of 12 living liver donors with narrowed remnant portal veins and treated with the "elbow patch reconstruction technique" were prospectively collected and retrospectively evaluated. Anatomic variation of the portal vein was defined in accordance with the Nakamura classification; six of the living liver donors had type A, three had type B, and the remaining three had type C. In eight of the living liver donors with a narrowed remnant portal vein, diagnosis was detected by intraoperative Doppler ultrasonography and visual inspection by experienced transplant surgeons in the living donor hepatectomy procedure. In the remaining four living liver donors, diagnosis was performed postoperatively when elevation of liver enzymes was noticed during the routine liver function test and Doppler US. The diagnosis was confirmed by multidetector computed tomography. Results: Data from nine males and three females aged 18 to 54 years were analyzed. All of the living liver donors were followed up for a median of 1710 days (min-max: 1178-4447 days; IQR: 1516 days), and none of the living liver donors had any structural or functional complications in the portal vein. Conclusions: Narrowing remnant portal veins are rare, but they are a life-threatening complication in living liver donors, and this condition requires urgent management. Image guided interventions and narrowed segment resection with end-to-end anastomosis using a vascular graft carried a potential risk for thrombosis and restenosis. To avoid these complications, we shared a technique named "elbow patch reconstruction technique". This technique can be very effective in relieving the narrowing of the remnant portal vein after right lobe living donor hepatectomy.

Diagnostic and therapeutic management algorithm for biliary complications in living liver donors.

This study aimed to demonstrate the efficacy of our diagnostic and therapeutic management algorithm and catheter-assisted (percutaneous transhepatic biliary tract drainage [PTBD] or transanastomotic feeding tube) hepaticojejunostomy (HJ) procedures in living liver donors (LLDs) with biliary complications. Living donor hepatectomy (LDH) was performed between September 2005 and April 2021 in 2 489 LLDs. Biliary complications developed in 220 LLDs (8.8%), 136 of which were male, and the median age was 29 (interquartile range [IQR]: 12) years. Endoscopic sphincterotomy ± stenting was performed in 132 LLDs, which was unsuccessful in 9 LLDs and required HJ. Overall, 142 LLDs underwent interventional radiologic procedures. Fifteen LLDs with biliary complications underwent HJ (PTBD catheter = 6 and transanastomotic feeding tube = 9) at a median of 44 days (IQR: 82). Following HJ, 14 LLDs did not have any complications throughout the median follow-up period of 1619 days (IQR: 1454). However, percutaneous dilation for HJ anastomotic stricture was performed in one patient. Biliary complications are very common following LDH; therefore, surgeons in the field should have a low threshold to perform HJ for biliary complications that persist after other treatments. Our catheter-assisted HJ techniques demonstrated a high success rate and aided HJ in a hostile abdomen during revisional surgery.

Microvascular Venous Invasion in Hepatocellular Carcinoma: Why Do Recurrences Occur?

PURPOSE: Hepatocellular carcinoma is the most common primary cancer of the liver. It is almost always associated with cirrhosis and it is usually diagnosed in later stages of the disease. Furthermore, recurrence rate following liver transplantation ranges between 15 and 30%. The most important factor determining the recurrence is vascular invasion. METHODS: In this review, the issue of microvascular invasion causing hepatocellular carcinoma recurrence is reviewed. Macroscopic vascular invasion is almost easy to diagnose on radiologic evaluation. However, microscopic vascular invasion is almost always diagnosed with pathologic evaluation. On the other hand, microscopic vascular invasion is associated with early recurrences and reduced disease-free survival. The type of vessel that is invaded determines the nature of the spread of the tumor cells. Invasion of the hepatic venous tributaries leads to systemic metastasis whereas portal venous invasions lead to intrahepatic spread of the tumor. Microscopic vascular invasion should be diagnosed before liver transplantation or liver resection in order to deliver the appropriate therapy to the patients. RESULTS: Yet, there is no ideal marker to suggest microscopic vascular invasion before any intervention. Markers such as alpha-fetoprotein, des carboxy prothrombin, or gamma-glutamyl transferase have been found to be correlated with microscopic vascular invasion. These parameters are not very efficient to be used in routine clinical practice. CONCLUSION: Therefore, further research is needed to define ideal marker associated with microscopic vascular invasion.

Is peritoneal dialysis prior to kidney transplantation a risk factor for ureteral stenosis after adult to adult live kidney transplantation.

OBJECTIVES: Major urinary complications such as urinary leaks, stenosis or urinary tract infections after kidney transplantation can lead to graft or patient loss. The effect of peritoneal dialysis on post-kidney transplantation complications have been discussed but its effect on ureteral stenosis is unknown. In this study, it was aimed to analyze factors effecting major ureteral complications after living donor kidney transplantation and impact of peritoneal dialysis and double J-stents (JJ stents). MATERIAL AND METHODS: This study included 116 adult to adult living donor kidney transplant patients. Factors effecting major urologic complications after living donor kidney transplantation were analyzed. The donors were primary relatives of the recipients. RESULTS: Major urologic complications after living donor kidney transplantation was 8/116 (6.9%). Urinary leak was present in 2 (1.7%) patients. Ureteral stenosis was encountered in 6 (5.2%) patients. Double J stents were used in 84 (72.4%) of the cases. The effect of JJ ureteral stent was not statistically significant for urinary leak, ureteral stenosis (p= 0.074, p= 0.470, respectively). A total of 29 (25%) patients had peritoneal dialysis before kidney transplantation. Preoperative peritoneal dialyses and bacteriuria after kidney transplantation were independent risk factors for ureteral stenosis in multivariate analysis (p= 0.013, and p= 0.010 respectively). CONCLUSION: In the guidance of the results of the present study, peritoneal dialysis prior to kidney transplantation and bacteriuria are independent risk factors for ureteral stenosis after living donor kidney transplantation. JJ stents have no effect on urologic complications after living donor kidney transplantation.

Liver Transplantation for Hepatocellular Carcinoma: Malatya Experience and Proposals for Expanded Criteria.

Survival was examined from a Turkish liver transplant center of patients with HCC, to identify prognostic factors. Data from 215 patients who underwent predominantly live donor liver transplant for HCC at our institute over 12 years were included in the study and prospectively recorded. They were 152 patients within and 63 patients beyond Milan criteria. Patients beyond Milan criteria were divided into two groups according to presence or absence of tumor recurrence. Recurrence-associated factors were analyzed. These factors were then applied to the total cohort for survival analysis. We identified four factors, using multivariate analysis, that were significantly associated with tumor recurrence. These were maximum tumor diameter, degree of tumor differentiation, and serum AFP and GGT levels. A model that included all four of these factors was constructed, the 'Malatya criteria.' Using these Malatya criteria, we estimated DFS and cumulative survival, for patients within and beyond these criteria, and found statistically significant differences with improved survival in patients within Malatya criteria of 1, 5, and 10-year overall survival rates of 90.1%, 79.7%, and 72.8% respectively, which compared favorably with other extra-Milan extended criteria. Survival of our patients within the newly defined Malatya criteria compared favorably with other extra-Milan extended criteria and highlight the usefulness of serum AFP and GGT levels in decision-making.

Analysis of risk factors of mortality in abdominal trauma.

BACKGROUND: The present study aims to analyze blunt and penetrating abdominal traumas that were evaluated in our emergency department, the treatment approaches and risk factors of mortality. METHODS: Six hundred and sixty-four patients were admitted to our emergency department for surgical evaluation for trauma between January 2009 and April 2019. After the exclusion of dead on arrival, patients with missing data and patients without abdominal trauma were excluded from this study. Hundred and thirteen patients with abdominal trauma admitted to our department were evaluated in this study. Demographic, clinical, prognostic and mortality related factors were retrospectively analyzed. RESULTS: The mean age of the patients was 36.08±16.1 years. There were 90 male patients. Eighty patients (70.8%) had blunt abdominal trauma (BAT). Twenty-eight patients (24.7%) had isolated liver and two patients (1.7%) had isolated spleen injury. Combined liver and spleen injury was found in two patients (1.7%). Twenty-two (19.4%) patients had mortality. Causes of mortality were an irreversible hemorrhagic shock (40.9%) and central nervous system (13.6%) injuries. BAT was the main mechanism of injury in patients with mortality (86.4% versus 67%; p<0.001). The frequency of retroperitoneal injury was significantly higher in patients with mortality (50% versus 16.5%, p<0.001). The frequency of extra-abdominal injury in patients with mortality was higher (68.1% versus 49.4%; p=0.047). Mean arterial pressure at admission was found to be significantly lower in patients with mortality (67±26.8 mmHg versus 84.3±17 mmHg; p=0.02). The number of packed erythrocytes transfused in patients with mortality was higher (8.8±8.6 versus 3.3±5.9 units; p=0.047). Mean international normalized ratio (INR) was significantly higher in patients with mortality (4.3±7.1 versus 2.7±4; p=0.016). Mean lactate dehydrogenase level was higher in patients with mortality (1685.7±333.8 versus 675.8±565.3 IU/mL; p<0.001). Mean alanine aminotransferase (ALT) was significantly higher in patients with mortality (430±619 versus 244±448 IU/mL; p<0.001). Mean alkaline phosphatase (ALP) level in patients with mortality was higher (76.9±72.8 versus 67.3±27.8 IU/mL; p=0.003). The presence of retroperitoneal injury and ALT >516 IU/mL were independent risk factors o mortality. CONCLUSION: We have found certain laboratory variables to increase in patients with mortality. These are related to the severity of trauma. Retroperitoneal injury and increased ALT levels being risk factors of mortality is the most important finding of this study. Our results can guide other centers in the evaluation of trauma patients, and high-risk groups can be identified.

Liver transplant for large hepatocellular carcinoma in Malatya: The role of gamma glutamyl transferase and alpha-fetoprotein, a retrospective cohort study.

BACKGROUND: There is increasing interest in transplanting patients with hepatocellular carcinoma (HCC) with tumors greater than 5 cm (Milan criteria). AIM: To investigate possible prognostically-useful factors for liver transplantation in HCC patients with large tumors. METHODS: In this clinical study, 50 patients with HCC who were transplanted at our Liver Transplant Center between April 2006 and August 2019 and had tumors greater than 6 cm maximum diameter were retrospectively analyzed. Their survival and full clinical characteristics were examined, with respect to serum alpha-fetoprotein (AFP) and gamma glutamyl transpeptidase (GGT) levels. Kaplan-Meier survival estimates were used to determine overall survival and disease-free survival in these patients. The inclusion criterion was evidence of HCC. Exclusion criteria were the presence of macroscopic portal vein thrombosis or metastasis and a follow-up period of less than 90 d. RESULTS: Using receiver operating characteristic curve (ROC) analysis, cutoff values of AFP 200 ng/mL and GGT 104 IU/L were identified and used in this study. Significantly longer overall survival (OS) and disease-free-survival (DFS) were found in patients who had lower values of either parameter, compared with higher values.  Even greater differences in survival were found when the 2 parameters were combined. Two tumor size bands were identified, in searching for the limits of this approach with larger tumors, namely 6-10 cm and > 10 cm. Combination parameters in the 6-10 cm band reflected 5-year OS of 76.2% in patients with low AFP plus low GGT vs 0% for all other groups. Patients with tumors greater than 10 cm, did not have low AFP plus low GGT. The most consistent clinical correlates for longer survival were degree of tumor differentiation and absence of microscopic portal venous invasion. CONCLUSION: Serum levels of AFP and GGT, both alone and combined, represent a simple prognostic identifier in patients with large HCCs undergoing liver transplant-ation.

Graft-versus-host disease after living donor liver transplantation: an unpredictable troublesome complication for liver transplant centers.

OBJECTIVE: The aim of this study was to report on graft-versus-host disease (GvHD) following living donor liver transplantation (LDLT). METHODS: Between May 2002 and January 2019, a total of 2387 LT procedures were performed in our Liver Transplantation Institute. Seven patients (0.29%) were admitted to our outpatient clinic with signs and symptoms compatible with GvHD following LT. Demographic, clinical and histopathological characteristics of patients with GvHD were retrospectively evaluated. RESULTS: There were six male and one female patient aged from 18 months to 67 years. Acute GvHD was detected in six patients and chronic GvHD in one. Grade II GvHD was detected in six patients, and Grade IV was detected in one patient. Time from LT to GVHD ranged from 4 to 657 days (median: 59 days). Time from beginning of clinical findings to histopathological diagnosis ranged from 2 to 160 days (median: 7 days). Initial clinical manifestations were as follows: skin rash + diarrhea (n = 2), skin rash (n = 2), skin rash + flushing (n = 1), diarrhea (n = 1), and skin rash + fever (n = 1). Despite intensive treatments, five out of seven patients (71.4%) died due to sepsis (n = 4) and gastrointestinal hemorrhage (n = 1). The remaining two patients are still alive without complications. CONCLUSION: GvHD is a life-threatening complication despite aggressive treatment. To achieve success in GvHD, preventive measures, early diagnosis, early initiation of treatment, antimicrobial prophylaxis, and proper supportive care should be ensured.

Usability of Inferior Vena Cava Interposition Graft During Living Donor Liver Transplantation: Is This Approach Always Necessary?

PURPOSE: To share the outcome of caval reconstruction technique in patients who underwent living donor liver transplantation (LDLT) with inferior vena cava (IVC) interposition grafting. METHODS: Between January 2009 and December 2018, an artificial or homologous interposition vascular graft was used for the continuity of resected native (IVC) due to various reasons in 29 of 1740 patients who underwent LDLT at our institute. Demographic, clinical, and radiological data were prospectively collected and retrospectively analyzed. RESULTS: Sixteen female and 13 male patients ranging 6-67 years of age were included. Right, left, and left lobe lateral segments were used in 22, 5, and 2 patients, respectively. The three leading LDLT indications were primary or idiopathic Budd-Chiari syndrome (BCS) (n = 12), alveolar echinococcosis (n = 7), and secondary BCS (n = 5). The three leading indications for IVC interposition grafting were thrombosis, dense fibrosis, and IVC invasion caused by tumor or echinococcosis. Homologous IVC graft was used in 17, homologous aortic graft in 7, and Dacron graft in 5 patients. Throughout the follow-up period, ascites ± pleural effusion and elevated liver enzymes were detected in 12 and 4 patients, respectively. Stenosis and/or thrombosis requiring one or more procedures such as 1-6 sessions balloon angioplasty, stent, and thrombus aspiration were observed in half of the patients. CONCLUSION: Retrohepatic IVC damages are not a contraindication for LDLT. The presence or absence of venous collateral circulation is an important indicator of the need for IVC interposition graft use.

Eligibility of Circumferential Fence With the Autologous Peritoneal Patch for Venous Reconstruction in Right Lobe Living-Donor Liver Transplant: A Case Control Study.

OBJECTIVES: : Our aim was to evaluate the eligibility of hepatic venous drainage technique using circumferential fence with peritoneal patch graft and saphenous vein graft in right lobe living-donor liver transplant. MATERIALS AND METHODS: Between November 2007 and December 2017, our center performed 1413 rightlobe living-donor liver transplants. A circumferential fence was created using the peritoneal patch graft for venous drainage reconstruction in 31 of these patients. We compared data of these 31 patients with data of 62 patients who had circumferential fence created with cryopreserved homologous saphenous vein graft (1:2 ratio). Patients with anastomotic stenosis (n = 10) and without anastomotic stenosis (n = 69) were also compared. RESULTS: No statistically significant differences were found between the peritoneal patch graft group and the saphenous vein graft group in terms of clinical parameters, circumferential fence diameter, and postoperative anastomotic stenosis (7.1% vs 26.1%; P = .056). Postoperative anastomotic stenosis developed in 10 patients. No statistically significant differences were found between patients with and without anastomotic stenosis in terms of clinical parameters except for diameter of circumferential fence (P = .001). Diameter of circumferential fence less than 18 mm in patients with and without anastomotic stenosis was shown in 80% and 34.6% of patients, respectively (P = .02). Stenosis-free survival in saphenous vein graft group was significantly better than in the peritoneal patch graft group (P = .023). Our correlation analyses showed a strong correlation between diameter of circumferential fence and the tenosis rate in patients (P = .001). CONCLUSIONS: Autologous peritoneal patch graft can be used for creating circumferential fence for hepatic outflow in living-donor liver transplant patients if no better option is available. Despite high anastomotic stenosis rates, peritoneal fencing responded well to radiologic dilatation or stent applications and provided good long-term patency.

Carcinoid tumors of appendix presenting as acute appendicitis.

BACKGROUND: We aim to present the data of patients who underwent appendectomy due to acute appendicitis, and incidental carcinoid tumor was detected on pathology. METHODS: Retrospective analysis of the patient charts between January 1999 and September 2018 were performed. RESULTS: 2778 appendectomy was performed due to acute appendicitis. Appendiceal carcinoid tumor was detected in 12 (0.43%) patients. Eight patients were (66.7%) female. Median age 37.5 years (range: 21-60). The median tumor size was 0.7 cm (range: 0.1-2.5). No perforation was detected. Eleven patients underwent appendectomy, and one patient had right hemicolectomy. The median follow-up period was 41.5 months (range: 22-49). There were no recurrences. CONCLUSION: Appendix carcinoid tumors are quite rare, usually asymptomatic and diagnosed incidentally on histopathological examination after appendectomy. The treatment of carcinoid tumors of the appendix is directly related to the tumor size, localization, presence of lymphovascular and mesoappendix invasion, mitotic activation rate and level of Ki67. Thus, it is important to follow the histopathological results after appendectomy. The prognosis of appendix carcinoid tumors is very good if the appendix is non-perforated.

Management of Acute Cholecystitis During Pregnancy: A Single Center Experience.

BACKGROUND: This study aimed to present to evaluate the results of two different approaches in the management of acute cholecystitis during pregnancy: immediate surgery and delayed surgery following conservative management. METHODS: In this study, 20 pregnant women who were treated in our clinic for acute cholecystitis between 2010 and 2018 were included in the analysis. Demographic characteristics, parameters related with acute cholecystitis (gallbladder wall thickness, laboratory data), duration of hospitalization, readmission rates, and preterm labor rate were retrospectively evaluated. RESULTS: The median age was 29.5 years. The median gestational week was 20 (6-32) weeks. Laparoscopic cholecystectomy was performed in 6 (30%) patients on admittance. When compared with the conservative management group, patients who received immediate surgery had higher gallbladder wall thickness. WBC count, and CRP, ALT, AST, ALP, and GGT levels (p<0.05). Furthermore, readmission rate and duration of hospitalization were lower in the patients who underwent immediate surgery (p<0.05). The preterm labor rate in conservative management and immediate surgery groups were 28.5% and 0%, respectively (p>0.05). CONCLUSION: In this study, even though these patients had thicker gallbladder wall and higher inflammatory markers suggesting severe inflammation, the outcome of early surgery was better than conservative management. Although the characteristics of the conservative management group was more favorable, complication rate seemed to be high.

Comparison of clinical and histopathological features of patients who underwent incidental or emergency appendectomy.

BACKGROUND: Incidental appendectomy can be defined as the removal of a clinically normal appendix during another surgical procedure unrelated to appendicitis or other appendicular diseases. AIM: To compare the demographic, biochemical, and histopathological features of the patients who underwent incidental and standard appendectomy. METHODS: The demographic, biochemical, and histopathological data of 72 patients (Incidental App group) who underwent incidental appendectomy during living donor hepatectomy at our Liver Transplant Center between June 2009 and December 2016 were compared with data of 288 patients (Acute App group) who underwent appendectomy for presumed acute appendicitis. The Incidental App group was matched at random in a 1:4 ratio with the Acute App group in the same time frame. Appendectomy specimens of both groups were re-evaluated by two experienced pathologists. RESULTS: Statistically significant differences were found between groups in terms of age (P = 0.044), white blood cell count (P < 0.001), neutrophil (P < 0.001), lymphocyte (P < 0.001), red cell distribution width (P = 0.036), mean corpuscular hemoglobin (P = 0.001), bilirubin (P = 0.002), appendix width (P < 0.001), and presence of acute appendicitis histopathologically (P < 0.001). However, no statistically significant differences were found between groups in terms of gender, platelet, mean platelet volume, mean corpuscular volume, platelet distribution width, appendix length. While the most common histopathological findings in the Incidental App group were normal appendix vermiformis (72.2%), fibrous obliteration (9.7%) and acute appendicitis (6.9%), the most common histopathological findings in the Acute App group were non-perforated acute appendicitis (62.8%), perforated appendicitis (16.7%), lymphoid hyperplasia (8.3%), and appendix vermiformis (6.3%). CONCLUSION: Careful inspection of the entire abdominal cavity is useful for patients undergoing major abdominal surgery such as donor hepatectomy. We think that experience is parallel to the surgeon's foresight, and we should not hesitate to perform incidental appendectomy when necessary.

The management of acute appendicitis in liver transplant patients: How effective is the Alvarado score?

OBJECTIVE: The incidence of acute appendicitis after liver transplantation (LT) is extremely low, reported to be 0.09% to 0.49%, but the efficacy of the Alvarado score in this patient group has not been studied. This study was an investigation of the clinical management of patients who developed acute appendicitis after LT and the usefulness of the Alvarado score in the diagnosis. METHODS: The study was performed using the data of 7 patients treated for acute appendicitis who were among 1990 patients who underwent LT between March 2002 and July 2017. The Alvarado score of the patients was calculated and reliability was analyzed. RESULTS: In this study, the incidence of acute appendicitis in LT patients was 0.35%. All of the patients were in the adult age group; 86% were male. The mean age was 46.4±10.7 years and the timeframe for the development of appendicitis after transplantation was a median of 12 months (range: 4-101 months). The median Alvarado score was 7 (range: 5-9). All of the patients had an Alvarado score above 5 and 71% had a score of 7 or more. CONCLUSION: Acute appendicitis is very rare in LT patients. As with non-transplant patients, Alvarado scoring can be safely performed in LT patients.

Two cases of laparoscopic total colectomy with natural orifice specimen extraction and review of the literature.

We present two cases of natural orifice specimen extraction (NOSE) after laparoscopic total colectomy and ileorectal anastomosis (TC-IRA), and we also review all of the previously reported cases. Our aim was to focus on patient selection for NOSE after TC-IRA. The PubMed and Google Scholar databases were scanned. Demographic features, surgical indications, and techniques were analyzed. Basic calculations were used for statistical analysis. A total of 13 cases were detected in addition to our 2 cases. All of the specimens were removed through the natural orifices successfully. No case required a diverting ileostomy. No patients were converted to open surgery or to conventional laparoscopy. Complications were reported in three patients. Transanal extractions were performed in 12 cases (10 colonic inertia, 2 polyposis), and transvaginal extractions were performed in 3 cases (2 malignancy, 1 colonic inertia). Both transanal and transvaginal specimen extractions after laparoscopic TC-IRA can be preferred. However, transanal extraction seems to be feasible in cases of TC for benign disease with a limited mesenteric-omental resection. If the indication is a malignancy requiring a mesenteric-omental resection, a transvaginal route should be preferred for a voluminous specimen.

Consequences of the use of extended criteria donors in living donor liver transplantation.

BACKGROUND: Donor selection criteria are being continuously modified to expand the potential donor pool in living donor liver transplantation (LDLT). This retrospective study reports our center's experience in utilizing extended criteria donors for LDLT. MATERIAL AND METHODS: The charts of 342 LDLT donors who underwent right hepatectomy between September 2007 and December 2010 were reviewed. Donors who were older than 55 years, and/or with BMI >30, and/or with a remnant liver volume of <30% were defined as extended criteria donors. The surgical complications in the extended criteria donors and non-extended criteria donors were compared. RESULTS: There were 61 extended criteria donors (21 male, 40 female; mean age 41 years) and 281 non-extended criteria donors (189 male, 92 female; mean age 31 Years). Surgical morbidities were observed in 70 (20.4%) of donors. The number of patients with complications according to Clavien's system were: Grade I, 30 (43%); Grade II, 11 (16%); Grade IIIa, 12 (17%); Grade IIIb, 16 (23%); and Grade IV, 1 (1%). Postoperative complications were observed in 17 (28%) of 61 extended criteria donors, and 53 (19%) of 281 non-extended donors (p>0.05). However, only the Grade IIIb complication rate in donors with extended criteria was significantly higher than in non-extended criteria donors (p=0.04). Complications developed in 3 of 7 donors aged >55 years and with BMI >30. There was no donor mortality. CONCLUSIONS: Although there was no statistical difference between the 2 groups' postoperative complication rates, Grade IIIb complications were statistically significantly higher in the extended group. Having more than 1 extended criteria may increase the donor's postoperative complications in LDLT. Thus, the elimination of the donors should be considered in the presence of more than 1 extended criteria.

Conversion to Stoppa procedure in laparoscopic totally extraperitoneal inguinal hernia repair.

BACKGROUND AND OBJECTIVES: Conversion to open surgery is an important problem, especially during the learning curve of laparoscopic totally extraperitoneal (TEP) inguinal hernia repair. METHODS: Here, we discuss conversion to the Stoppa procedure during laparoscopic TEP inguinal hernia repair. Outcomes of patients who underwent conversion to an open approach during laparoscopic TEP inguinal hernia repair between September 2004 and May 2010 were evaluated. RESULTS: In total, 259 consecutive patients with 281 inguinal hernias underwent laparoscopic TEP inguinal hernia repair. Thirty-one hernia repairs (11%) were converted to open conventional surgical procedures. Twenty-eight of 31 laparoscopic TEP hernia repairs were converted to modified Stoppa procedures, because of technical difficulties. Three of these patients underwent Lichtenstein hernia repairs, because they had undergone previous surgeries. CONCLUSION: Stoppa is an easy and successful procedure used to solve problems during TEP hernia repair. The Lichtenstein procedure may be a suitable option in patients who have undergone previous operations, such as a radical prostatectomy.
