The Effect of Age on Pancreaticoduodenectomy; Comorbidities, Short-term Outcomes, and Survival.

OBJECTIVE: To evaluate the complications, mortality, and survival rates of patients aged >70 years undergoing pancreaticoduodenectomy, and to determine associated risk factors. STUDY DESIGN: Descriptive study. Place and Duration of the Study: General Surgery Clinic of Eskisehir Osmangazi University Medical Faculty Hospital, Eskisehir, Turkiye, from January 2014 to September 2020. METHODOLOGY: A retrospective scrutiny of 94 patients who had undergone pancreaticodueodenectomy, was carried out. The patients were separated into two age groups of younger and older than 70 years, and were compared in respect of clinicopathological characteristics, comorbidities, perioperative characteristics, and complications. Independent risk factors for the endpoints of perioperative mortality and survival were investigated. RESULTS: No significant difference was determined between the groups in respect of biochemical values, and perioperative and histochemical characteristics. Comorbidities were present at a higher rate in the older patients (77.8% vs. 38.8%, p<0.001). The postoperative complication rates were similar (33.3% vs. 32.7%, p=0.944). Perioperative mortality (first 30 days) was determined at a significantly higher rate in the older age group (20.0% vs. 4.1%, p=0.016). The age of patients >70 years increased the risk of mortality 4.851-fold but was not an independent predictive factor (p=0.086). The groups were similar in respect of disease-free survival (DFS) and overall survival (OS, Log-rank p=0.780, p=0.386). Age [Hazard Ratio (HR): 1.029, p=0.048] and pancreas adenocarcinoma (HR: 1.846, p=0.028) were determined to be independent prognostic factors for DFS, and pancreas adenocarcinoma (HR 1.940, p=0.023) for OS. CONCLUSION: Older age was not seen to change survival in patients undergoing pancreaticoduodenectomy, but mortality within the first 30 days was affected. Age is not accepted as an absolute contraindication. It is recommended that pancreaticoduodenectomy is performed on patients aged >70 years with careful patient selection, prudent preoperative preparation, a meticulous surgical technique, and close multidisciplinary postoperative support. KEY WORDS: Pancreaticoduodenectomy, Elderly, Comorbidity, Complication, Mortality, Survival.

Ethyl Pyruvate; from Liver Preservation Solutions University of Wisconsin (UW) Increases the Effectiveness of the Solution.

BACKGROUND: The most important factor affecting the success rate of liver transplants is the preservation of the normal histologic and biochemical properties of the cells in the tissue taken. The study aimed to identify the possible increase in efficacy of ethyl pyruvate, which has a hepatoprotective effect, on the University of Wisconsin (UW) solution. METHODS: Rats were randomly selected and divided into 4 groups. After a laparotomy, the small intestines were removed from the abdomen and the portal pedicle was identified. Arterial and venous circulation of the liver was interrupted. After the portal vein was cannulated (and the distal of the portal pedicle was ligated, the liver was perfused with a solution. Perfusion solution was selected as Ringer Lactate in Group 1. In group 2, UW solution was chosen as the perfusion solution. In Group 3, the perfusion solution was chosen as the UW solution, but ethyl pyruvate at a dose of 40 mg/kg was administered intraperitoneally to the experimental animals 30 minutes before hepatectomy. In Group 4, as a perfusion solution, a UW solution with 40 mg/kg dose of ethyl pyruvate added to it was used. RESULTS: With TUNEL and Caspase-3 staining, a significant decrease was found in the apoptosis rates of Groups 2, 3, and 4 at the 12th hour post hepatectomy when compared with Group 1. When the morphometric liver sinusoid/parenchyma ratios and vena centralis diameters of the groups were examined, it was found that all preservation solutions containing the UW solution were more protective than the RL solution. CONCLUSIONS: Ethyl pyruvate is regarded as a promising agent that can increase the effect of the UW solution on organ preservation solutions. Because this study is the first in literature to apply ethyl pyruvate in preservation solutions, additional studies with larger series and different doses are needed.

Lateral lymph node involvement presents another challenge in rectum cancer in the age of neoadjuvant chemoradiotherapy + total mesorectal excision: an evaluation of survival outcomes.

PURPOSE: In the last decades, total mesorectal excision (TME) and neoadjuvant chemoradiotherapy (nCRT) have produced an undeniable improvement in the treatment of rectal cancer. However, local recurrence is still an important problem, and the effect of lateral lymph node (LLN) involvement on local recurrence is a controversial issue. The aim of this study was to investigate the effects of LLN status on local recurrence and survival in rectal cancers treated with nCRT + TME. METHODS: Clinical features, pre- and post-nCRT lateral pelvic region imaging, long-term local recurrence, and the survival outcomes of 114 patients who underwent nCRT + TME for rectal cancer were evaluated. RESULTS: On MRI before nCRT, 20 (17.5%) patients had lateral lymph nodes (LLN+), and 94 (82.5%) patients had no lymph nodes in the lateral pelvic compartments (LLN-). Local recurrences at 1 year in LLN+ and LLN- patients were 3 (15.8%) and 2 (2.3%), respectively (p=0.039). Five-year local recurrence-free survival rates and the mean duration of recurrence-free survival in LLN+ and LLN- patients were 56.2%, 42.6 months, and 87.3% 66.9 months, respectively (p=0.001). Disease-free survival and overall survival were shorter in LLN+ patients, but the difference was not statistically significant (p=0.096 and p=0.46, respectively). In the multivariate analysis, LLN involvement was determined to be an independent risk factor for local recurrence-free survival (Hazard Ratio 4.54, p=0.003). CONCLUSION: Lateral lymph node involvement causes local recurrence to remain high after nCRT + TME. LLN status should be considered in treatment planning. Further studies are needed to define precise criteria for LLN involvement and the effect of LLND on local recurrence and survival.

Distal spread and tumor regression patterns following preoperative chemoradiotherapy in rectal cancer patients

Background/aim/AIM: This study aimed to evaluate the regression pattern with the distal intramural spread (DIS) of rectum cancer after preoperative chemoradiation. Materials and methods: Specimens from 56 patients who underwent radical resection after preoperative chemoradiation for rectal cancer were examined. The regression pattern (total, fragmented) of the tumor was recorded. DIS status was evaluated by creating sections 0.2 to 0.3 cm thick. Results: A single macroscopic residual area was detected in all specimens. In 10 patients (17.8 %), pathologically complete responses were identified, and DIS was detected in 33 patients (58.9%). The average DIS distance was 0.56± 0.3 cm (range 0.2 ­ 1.8 cm); the spread was < 1 cm in 87.9% of the patients (29/33). The overall survival rates for 5 and 7 years were 76.8% and 73.2%, respectively. The survival rates between patients with and without DIS were not statistically different (94.6± 5.5 vs. 75.1 ± 10.2 months, respectively). In all of the patients, tumor regression pattern was total shrinkage of the tumor. Conclusion: A sufficient distal resection margin for rectal cancer after preoperative chemoradiation is 1 cm in the vast majority of cases. However, DIS may exceed 1 cm in a small proportion of patients.

Results of positive proximal margin after resection for hilar cholangiocarcinoma: An analysis of 42 cases.

BACKGROUND/AIMS: Hilar cholangiocarcinoma (HC) is a tumor that invades the confluence of the left and right hepatic bile ducts. Surgery is the definitive treatment but is also technically demanding. Here, we report our experience on 42 patients who underwent surgical resection for HC. The aim of the present study was to evaluate the margin status of resected specimens on frozen sections and the impact of R1 resection margin on survival. MATERIALS AND METHODS: A total of 42 patients with HC who underwent surgical resection in our clinic between January 2008 and January 2017 were included in the study. Patients' charts were evaluated retrospectively. RESULTS: The 1-, 2-, and 4-year overall survival rates of the 42 patients were 76.2%, 40%, and 10.7%, respectively. The median survival rates of the patients with negative and positive proximal surgical margins were 22 (11.93-32.06) and 17 (14.43-19.56) months, respectively. There was no statistically significant difference between these two groups. CONCLUSION: In HC, surgery achieving negative proximal surgical margin is often very difficult. Our results demonstrate that frozen sections are reliable for the assessment of the invasion status of the proximal and distal ductal surgical margins. Although complete resection is potentially curative, survival of the patients with HC is still poor. If there is no distant metastasis at the time of diagnosis, then extirpating surgery should be encouraged as survival of the patients with positive and negative margins is not significantly different.

Endoscopic Treatment of the Coloanal Anastomotic Dehiscence and Stricture: Stenting Via Rendezvous Technique.

An anastomotic leak is a serious complication of colorectal surgery. Leak management is often grueling, and a definitive stoma is often mandatory for rescue therapy. Herein, we present a patient who experienced coloanal anastomotic dehiscence and complete stricture at the proximal part of the anastomosis. This case was successfully treated with a fully covered self-expandable metallic stent placement via the combined endoscopic (per ileostomy) and manual (per anal channel) rendezvous technique.

Pancreatic stump closure using only stapler is associated with high postoperative fistula rate after minimal invasive surgery.

BACKGROUND/AIMS: Postoperative pancreatic fistula (POPF) is the most common cause of morbidity and mortality after distal pancreatectomy (DP). The aim of the present study is to determine the risk factors that can lead to POPF. MATERIALS AND METHODS: The study was conducted between January 2008 and December 2012. A total of 96 patients who underwent DP were retrospectively analyzed. RESULTS: Overall, 24 patients (25%) underwent laparoscopic distal pancreatectomy (LDP) and 72 patients (75%) open surgery. The overall morbidity rate was 51% (49/96). POPF (32/96, 33.3%) was the most common postoperative complication. Grade B fistula (18/32, 56.2%) was the most common fistula type according to the International Study Group on Pancreatic Fistula definition. POPF rate was significantly higher in the minimally invasive surgery group (50%, p=0.046). POPF rate was 58.6% (17/29) in patients whose pancreatic stump closure was performed with only stapler, whereas POPF rate was 3.6% (1/28) in the group where the stump was closed with stapler plus oversewing sutures. Both minimally invasive surgery (OR: 0.286, 95% CI: 0.106-0.776, p=0.014) and intraoperative blood transfusion (OR: 4.210, 95% CI: 1.155-15.354, p=0.029) were detected as independent risk factors for POPF in multi-variety analysis. CONCLUSION: LDP is associated with a higher risk of POPF when stump closure is performed with only staplers. Intraoperative blood transfusion is another risk factor for POPF. On the other hand, oversewing sutures to the stapler line reduces the risk of POPF.

Mixed Adeno-Neuroendocrine Carcinoma; Case Series of Ten Patients with Review of the Literature

Aims: Mixed adeno-neuroendocrine carcinoma is a rare entity, diagnosed with immunohistochemical studies. Literature mainly includes case reports and series which are very few. In our study, we aimed to report a case series from a tertiary hospital with demographics of the patients, detailed tumor and clinical findings and follow-up plus survival conditions. Methods: Pathology database was explored for patients with the pathological diagnosis of 'mixed adeno-neuroendocrine carcinoma' and patients were identified retrospectively and evaluated in means of demographics, histopathological examination, tumor properties. Results: Ten patients had been diagnosed with mixed adeno-neuroendocrine carcinoma in our center, diagnosed at a mean age of 64.7. Stomach was found to be the most common localization. Five patients (50%) were diagnosed as grade 3. Following surgery, median follow-up was 15 months with a median survival time of 20.6 months. Conclusion: This case series may contribute to the literature on the pathological and clinical aspects of the mixed adenoneuroendocrine carcinoma of the gastrointestinal system.

Comparison of Early Postoperative Outcomes after Total Gastrectomy and D2 Lymph Node Dissection with and without Splenectomy.

BACKGROUND: A famous prognostic ingredient for gastric cancer is the lymph node metastasis. Previously in the therapy of gastric cancer, splenectomy was considered as a definitive part of lymph node dissection. Currently, preservation of the spleen is the accepted approach during total gastrectomy and routine splenectomy is abandoned. The aim of this study was to estimate the impression of splenectomy for D2 lymph node dissection with total gastrectomy. METHODOLOGY: Between February 1998 and January 2012, 1531 patients underwent gastric cancer surgery. Of these 257 patients, 205 patients underwent total gastrectomy with splenectomy, and the remaining 52 underwent a spleen-preserving total gastrectomy. RESULTS: No statistical difference between these two groups in terms of age, gender, comorbidity, stage and American Society of Anesthesiologists score, surgical complications were detected. A significant difference was not seen in these groups with regard to postoperative mortality too. CONCLUSION: Early postoperative results were similar after TG ± splenectomy. Performing splenectomy did not increase the postoperative morbidity and mortality.How to cite this article: Oter V, Dalgic T, Ozer I, Colakoglu K, Cayci M, Ulas M, Bostanci EB, Akoglu M.

Management of Laparoscopic Cholecystectomy-Related Bile Duct Injuries: A Tertiary Center Experience.

BACKGROUND: Laparoscopic cholecystectomy (LC)-related bile duct injuries remains a challenging issue with major implications for patient's outcome. METHODS: Between January 2008 and December 2012, we retrospectively analyzed the management and treatment outcomes of 90 patients with bile duct injury following LC. RESULTS: Forty-seven patients (52.2%) were treated surgically while the remaining 43 patients (47.8%) underwent non-surgical intervention. Injuries of Strasberg Type A and C were significantly more frequent in the non-surgical intervention group (P = 0.016, P = 0.044) whereas Type E2 was more frequent in the definitive surgery group (P < 0.001). The success rate of non-surgical intervention decreased as the waiting time increased whereas the success of definitive surgery was not time-dependent (P = 0.048). Initial jaundice (direct biluribin >1.3 gr/dL) significantly reduced the success rate of non-surgical interventions (P = 0.017). Presence of intraabdominal abscess significantly increased the complication rate after both definitive surgery and non-surgical interventions (P = 0.04, P = 0.023). Treatment success rates were similar in both surgery and non-surgical intervention groups according to the distribution of Strasberg injury types. CONCLUSION: A multimodality approach is recommended in planning for patient-based treatment. Delayed referral reduces the success of nonsurgical interventions while it does not seem to significantly affect the success of surgical interventions when intraabdominal sepsis is under control.

Changing Trends in Gastric Cancer Surgery.

Gastric cancer is one of the most common causes of cancer-related death. It requires multimodal treatment and surgery is the most effective treatment modality. Radical surgery includes total or subtotal gastrectomy with lymph node dissection. The extent of lymphadenectomy still remains controversial. Eastern surgeons have performed D2 or more extended lymphadenectomy while their Western colleagues have performed more limited lymph node dissection. However, the trend has been changing in favour of D2 lymph node dissection in both hemispheres. Currently, D2 is the recommended type of lymphadenectomy in experienced centres in the west. In Japan, D2 lymph node dissection is the standard surgical approach. More extensive lymphadenectomy than D2 has not been found to be associated with improved survival and generally is not performed. Bursectomy and splenectomy are additional controversial issues in surgical performance, and trends regarding them will be discussed. The performance of bursectomy is controversial and there is no clear evidence of its clinical benefit. However, a trend toward better survival in patients with serosal invasion has been reported. Routine splenectomy as a part of lymph node dissection has largely been abandoned, although splenectomy is recommended in selected cases. Minimally invasive surgery has gained wide popularity and indications for minimally invasive procedures have been expanding due to increasing experience and improving technology. Neoadjuvant therapy has been shown to have beneficial effects and seems necessary to provide a survival benefit. Diagnostic laparoscopy should be kept in mind prior to treatment.

Risk Factors for Development of Biliary Complications after Surgery for Solitary Liver Hydatid Cyst.

Biliary leakage (BL) is the most common cause of postoperative morbidity after conservative liver hydatid cyst surgery. The objective of this study was to determine incidence of BL and related risk factors in patients with solitary liver hydatid cyst who underwent conservative surgery. A total of 186 patients were included in this study. Age, gender, cyst recurrence, diameter, and localization, World Health Organization Informal Working Group on Echinococcosis (WHO-IWGE) classification, cavity management techniques, cyst content, and alkaline phosphatase (ALP) levels were evaluated with univariate and multivariate analyses. Of these patients 104 were female and 82 were male. The mean age was 43.5 ± 14.7 years. Postoperative BL was detected in 36 (19.4%) patients. Cyst diameter (P = 0.019), cyst localization (P = 0.007), WHO-IWGE classification (P = 0.017), and ALP level (P = 0.001) were the most significant risk factors for BL. Independent risk factors for BL were perihilar localization, large cyst diameter, high ALP level, and advanced age according to WHO-IWGE classification.

A Retrospective Analysis of Factors Affecting Early Stoma Complications.

Despite advances in surgical techniques and products for stoma care, stoma-related complications are still common. A retrospective analysis was performed of the medical records of 462 consecutive patients (295 [63.9%] female, 167 [36.1 %] male, mean age 55.5 ± 15.1 years, mean body mass index [BMI] 25.1 ± 5.2) who had undergone stoma creation at the Gastroenterological Surgery Clinic of Turkiye Yuksek Ihtisas Teaching and Research Hospital between January 2008 and December 2012 to examine the incidence of early (ie, within 30 days after surgery) stoma complications and identify potential risk factors. Variables abstracted included gender, age, and BMI; existence of malignant disease; comorbidities (diabetes mellitus, hypertension, coronary artery disease, chronic respiratory disease); use of neoadjuvant chemoradiotherapy; permanent or temporary stoma; type of stoma (loop/end stoma); stoma localization; and the use of preoperative marking of the stoma site. Data were entered and analyzed using statistical software. Descriptive statistics, chi-squared, and Mann-Whitney U tests were used to describe and analyze all variables, and logistic regression analysis was used to determine independent risk factors for stoma complications. Ostomy-related complications developed in 131 patients (28.4%) Of these, superficial mucocutaneous separation was the most frequent complication (90 patients, 19.5%), followed by stoma retraction (15 patients, 3.2%). In univariate analysis, malignant disease (P = .025), creation of a colostomy (P = .002), and left lower quadrant stoma location (P <.001) were all significant indicators of stoma complication. Only stoma location was an independent risk factor for the development of a stoma complication (P = .044). The rate of stoma complications was not significantly different between patients who underwent nonemergent surgery (30% in patients preoperatively sited versus 28.4% not sited) and patients who underwent emergency surgery (27.1%). Early stoma complication rates were higher in patients with malignant diseases and with colostomies. The site of the stoma is an independent risk factor for the development of stoma complication. Preoperative marking for stoma creation should be considered to reduce the risk of stoma-related complications. Prospective, randomized controlled studies are needed to enhance understanding of the more prevalent risk factors.

Surgical Outcomes of Solid Pseudopapillary Neoplasm of the Pancreas: A Single Institution's Experience of 16 Cases.

INTRODUCTION: Solid-pseudopapillary tumor (SPT) of the pancreas is a rare tumor, generally characterized by a well-encapsulated mass. The aim of the current study was to analyse the clinicopathological characteristics and treatment outcomes of patients with SPT. In this study, we report our clinical experience with 16 cases of SPTs. METHODS: Sixteen patients who underwent surgery for pathologically confirmed SPT were included. Data of the patients were reviewed from the prospectively recorded database. Patients' demographics, laboratory values, clinical presentation, radiological imaging findings, surgical treatment, perioperative complications, pathological features, post-operative course, and long-term survival were collected and analyzed. Statistical analyses were performed using the computer program Statistical Package for Social Sciences (SPSS) 16.0 for Windows. RESULTS: The tumors ranged from 2 to 11 cm in diameter and were located in the head in ten patients (62.5%), the neck in two patients (12.5%), and the body or tail in four patients (25%). All patients were women whose ages ranged from 21 to 79 years (mean age was 41.62 ± 15.08). Patients had resection margins free of tumor resections and there were no preoperative or postoperative mortalities. There was no recurrence or metastasis after the surgical resection. All patients were alive at a mean follow-up of 49.06 ± 29.53 months (range 6 to 99). CONCLUSION: SPT is a rare pancreatic neoplasm with a low malignant potential, and is common in young women. If SPT is diagnosed before surgery, complete surgical resection, generally enucleation is the most effective therapy for SPT.

The rationality of resectional surgery and palliative interventions in the management of patients with gallbladder cancer.

The aim of the present study was to evaluate in a retrospective manner, the survival period and survival rate according to stages and groups after R0, R1, R2 resections and palliative interventions. Between 2003 and 2012, 67 patients diagnosed with gallbladder carcinoma were retrospectively analyzed. Patient demographics, the survival period, and survival rate according to stages and groups after R0, R1, R2 resections and palliative interventions were retrospectively analyzed. Sixty-seven patients were diagnosed with gallbladder carcinoma. Thirty-eight patients (56.7%) were female and 29 patients (43.3%) were male. The median survival period was significantly longer in stage II and III diseases than in stage IV disease (P < 0.001). The R0, R1, and R2 resection rates in patients who underwent surgery with curative intent were 67.7, 19.4, and 12.9 per cent, respectively. The R0 resection rate according to the tumor stages was 100 per cent for stage I, 87.5 per cent for stage II, 66.7 per cent for stage III, and 42.8 per cent for stage IV disease. The median follow-up period was six months (eight days to 36 months). During this follow-up period, 53 patients (79.1%) died. In conclusion, R0 resection rate decreases when tumor stage increases. The highest survival rates after R0 resection are achieved in patients with stage I, II, and III diseases. Radical surgery has no benefit over palliative surgery for stage IV disease in terms of survival.

Solitary plasmacytoma of the cecum and the ascending colon: surgical resection as a treatment modality.

Colonic solitary plasmacytoma is a rare disease, with few reports occurring in the literature. Solitary plasmacytoma is defined as a plasma cell tumour with no evidence of bone marrow infiltration. Plasmacytoma can present as a solitary tumour in bone or in other parts of the body. The gastrointestinal tract is rarely the site of the disease. We report on the case of a 51-year-old man presenting with a colonic symptomatic mass with unclear biopsy results. A resected specimen showed a solitary plasmacytoma. Surgical resection was an adequate treatment modality in this case. Endoscopic resection, radiotherapy, and chemotherapy are also preferred treatments in selected gastrointestinal plasmacytoma cases.

Unresectable pancreatic adenocarcinoma with complete clinical response following chemoradiotherapy.

Locally advanced or metastatic disease is present in 2/3s of patients with pancreatic cancer. Pancreatic cancer patients are assessed as resectable, potentially resectable (borderline) and unresectable according to pre-operative examinations. The chance for operability may be enhanced by using adjuvant-neoadjuvant systemic chemotherapy, radiotherapy or both. The rates of R0 resection may be increased by means of treatment delivered this way. This case report presents a pancreatic adenocarcinoma case that was assessed to be resectable but was identified to be unresectable during surgical exploration, thus received adjuvant chemoradiotherapy. The patient was then re-evaluated, identified as resectable and received pancreaticoduodenectomy.

The analysis of clinico-pathologic characteristics in patients who underwent surgery due to stricturing and non-perineal fistulizing forms of Crohn's disease: a retrospective cohort study.

BACKGROUND: The diagnosis of Crohn's disease is based mainly on the patient's history and clinical examination and supported by serologic, radiologic, endoscopic, and histologic findings. AIMS: The main purpose of the present study was to evaluate in a retrospective manner the clinico-pathological characteristics of patients who underwent surgery due to stricturing or non perineal fistulizing Crohn's disease. MATERIAL AND METHODS: Between January 2007 and June 2012, 75 patients who were operated on for stricturing and non-perineal fistulizing forms of Crohn's disease were analyzed according to their clinico-pathological characteristics. RESULTS: The L3 localization (Montreal Classification) was detected significantly more often in the non-perineal fistulizing group than in the stricturing group (P < 0.03). Wound infection (18 patient, 24%) was the most commonly observed postoperative complication, followed by postoperative ileus (5 patients, 6.7%) and intraabdominal abscess (4 patients, 5.2%). The distribution of postoperative complications according to the two groups was not significantly different (P = 0.772). Submucosal fibrosis, ulcers and transmural inflammation were the three most common histopathological signs in resected specimens from both groups. Pseudopolyps, microabscess, granuloma, mononuclear inflammation and deep fissures were significantly far more frequent in the non perineal fistulizing group when compared to the stricturing group (P < 0.05). On the other hand, superficial ulcers were significantly more frequent in the stricturing group (P = 0.007). CONCLUSION: No specific clinical feature was found to differentiate patients with the stricturing form of Crohn's disease from the fistulizing form. However, histopathological analysis of the resected specimens revealed significant differences in some parameters between the two disease forms.

Modified single stapler technique in anterior resection for rectal cancer.

Technical difficulties during colorectal surgery increase the complication rates. We introduce a modified single stapler technique for patients in whom technical problems are encountered while performing double stapler technique. Before pelvic dissection, descending colon is divided at minimum 10 cm proximal to the tumoral segment. Tumor specific mesorectal excision is performed and two purse string sutures are placed at the distal margin with an interval of 1 - 2 cm. After introducing a circular stapler via the anus, the distal purse string suture is tied around the central shaft of the stapler and the proximal purse string suture around the colonic lumen. After the resection is completed between the two sutures, the anvil shaft is connected to the central shaft and the stapler is closed and fired. None of the patients had an anastomotic leak. This technique may be a safe alternative particularly in patients with narrow pelvis and distal tumors.

Brain Death after Liver Transplantation for Fulminant Hepatic Failure: A Report of Two Cases.
