RESUMO
BACKGROUND: We aimed to study the prognostic impact of sarcopenia on overall survival (OS), disease-free survival (DFS), and postoperative outcomes among patients with Hepatocellular carcinoma (HCC) who underwent curative hepatic resection. METHODS: Data were collected retrospectively from patients with HCC underwent curative hepatic resection and preoperative abdominal computed tomography (CT) at our institution between January 2010 and December 2020. Sarcopenia was evaluated by the skeletal muscle mass at the inferior direction of the third-lumbar-vertebra (L3) cross-sectional area based on preoperative CT imaging using software analysis. Cutoff values for skeletal muscle index (SMI) were 43.75 and 41.10 cm2/m2 for males and females. The patients were classified into sarcopenia and nonsarcopenia groups. The association between preoperative sarcopenia and clinicopathological factors, impact of sarcopenia on survival, and postoperative outcomes were analyzed. RESULTS: Sarcopenia was present in 39 of 83 (47.0%) patients who underwent curative hepatic resection for HCC and was significantly correlated with lower SMI, lower serum albumin levels, higher intraoperative blood loss, higher postoperative complications, and longer hospital stay. The 5-year OS was significantly lower in sarcopenic patients than in nonsarcopenic patients (58.2% vs 83.6%; P = .006), but the 5-year DFS was not significantly different between the 2 groups. Multivariate analysis revealed that sarcopenia was a significant risk factor for poor OS (HR 4.728; 95% CI, 1.458-15.329; P = .010). CONCLUSION: Sarcopenia was identified as a prognostic factor for poor OS after hepatic resection, and major postoperative complications were more frequent in sarcopenia. Early sarcopenia detection and management may improve OS and clinical outcomes in postoperative HCC.

Simple hepatic cysts are usually asymptomatic and rarely cause complications. Among the rare complications of liver cysts, intracystic hemorrhage is one of the most frequent, and can result in a rapid increase in cyst size. Some simple hepatic cysts may be large and can present with pressure effects, such as abdominal discomfort or obstructive jaundice. A 68-year-old female with a simple huge hepatic cyst was scheduled elective laparoscopic fenestration in 6 weeks. Before the operation, she developed acute cholangitis, resulting from an acute increase in cyst size due to intracystic hemorrhage. Upon open fenestration, 6.1 L of chocolate-like fluid was drained. A huge simple hepatic cyst complicated by intracystic hemorrhage resulted in an acute increase in cyst size. Distortion of the extrahepatic bile duct by the cyst obstructed the bile flow. Acute cholangitis was eventually developed.
RESUMO
Objectives: To investigate the risk factors for early recurrence after curative pancreatoduodenectomy for resectable pancreatic ductal adenocarcinoma. Methods: All data were retrospectively collected from patients with resectable pancreatic ductal adenocarcinoma who had undergone pancreatoduodenectomy at the Department of Surgery, Phramongkutklao Hospital, from January 2015 to December 2020. The preoperative and perioperative risk factors were included into the analysis. Results: In total, 34 patients were included in the study. The median time for recurrence and median survival time were 17 and 20 months, respectively. The 1, 3, and 5 year disease-free survival rates were 59.6%, 23.87%, and 23.87%, respectively, while the 1, 3, and 5 year overall survival rates were 81%, 24.7%, and 12.4%, respectively. Seventeen patients (50%) from a total of 34 patients had recurrence, and ten patients (29.41%) had recurrence within 12 months. The independent preoperative risk factor associated with adverse disease-free survival was tumor size > 4 cm (hazard ratio [HR], 14.34, p=0.022). The perioperative risk factors associated with adverse disease-free survival were pathological lymphovascular invasion (HR, 4.31; p=0.048) and non-hepatopancreatobiliary surgeon (HR, 5.9; p=0.022). Risk factors associated with poor overall survival were microscopical margin positive (R1) resection (HR, 3.68; p=0.019) and non-hepatopancreatobiliary surgeon (HR, 3.45; p=0.031). Conclusions: Tumor size > 4 cm from the preoperative imaging study was a poor prognostic factor for early recurrence after curative pancreatoduodenectomy for resectable pancreatic adenocarcinoma indicated that they may have radiological occult metastasis, thus, staging laparoscopy may reduce the number of unnecessary laparotomies and avoid missing radiologically negative metastases.
RESUMO
Type VI choledochal cysts or cystic duct dilatation cysts are a relatively new and rare condition. We report the case of a 35-year-old man who presented with a history of recurrent episodes of epigastrium pain. Magnetic resonance cholangiography revealed a cyst lodged between the cystic duct and the right anterior sectoral bile duct. He underwent a laparoscopic right anterior sectorectomy with cholecystectomy. Pathological examination revealed a cyst with a fibrous wall, dense chronic inflammatory infiltration, lined by columnar epithelium. Due to its rarity, the diagnosis is often made intraoperatively. The treatment of cystic duct cysts includes cholecystectomy, complete cyst excision, recontinuity of the common bile duct. Type VI choledochal cysts are extremely rare. Preoperative diagnosis, using either magnetic resonance cholangiopancreatography or endoscopic retrograde cholangiopancreatography, is vital to prevent postoperative complications. Treatment of this type of cysts includes cholecystectomy and complete cyst excision and biliary-enteric reconstruction if necessary.
RESUMO
Reactive lymphoid hyperplasia (RLH) of the liver is an extremely rare benign lesion, which is often misdiagnosed as a malignant liver tumour. We present the case of a 69-year-old man with an incidental liver tumour revealed on the ultrasonography of the kidney-urinary bladder system for benign prostatic hyperplasia. Hepatocyte-specific contrast (gadoxetate disodium) magnetic resonance imaging revealed a round 6-mm lesion, which was hypointense on T1-weighted images, slightly hyperintense on T2-weighted images and highly intense on diffusion-weighted images. Other findings included arterial hyperintensity, venous and delayed hypointensity and a defect in liver segment 6. The patient was diagnosed with hepatocellular carcinoma; laparoscopic partial hepatectomy was performed. Intraoperatively, a 7-mm greyish white solid nodule was observed. In conclusion, it may be difficult to distinguish RLH from other malignant liver tumours. However, it should be considered as a differential diagnosis for small liver lesions in young, female patients without liver cirrhosis.
RESUMO
Extensive surgery is the mainstay treatment for gallbladder cancer and offers a long-term survival benefits to the patients. However, the optimal extent of surgery remains debatable. We aimed to perform a meta-analysis of hepatectomy and no hepatectomy approaches in patients with T2 gallbladder cancer. We searched the following electronic databases for systematic literature: PubMed, Google Scholar, and the Cochrane Library. We selected studies that compared patients with T2 gallbladder cancer who underwent hepatectomy with those who did not. While the long-term overall survival (OS) and disease-free survival (DFS) were the primary outcomes, perioperative morbidity and mortality were the secondary outcome. We analysed over 18 studies with 4,587 patients. Of the total patients, 1,683 and 1,303 patients underwent hepatectomy and no hepatectomy, respectively. The meta-analysis revealed no significant difference between the hepatectomy and no hepatectomy groups, in terms of the overall morbidity (risk ratio [RR] = 1.85, 95% confidence interval [CI] = 0.66-5.20) and 30-day mortality (RR = 0.9, 95% CI = 0.1-8.2). The results were comparable in terms of the OS (RR = 0.76, 95% CI = 0.57-1.01), (HR = 0.74, 95% CI = 0.49-1.12), and DFS (RR = 0.99, 95% CI = 0.88-1.11). In conclusion, the perioperative and long-term outcomes of hepatectomy and no hepatectomy approaches were comparable. Hepatectomy may not be required in T2 gall bladder cancer if the preoperative evaluation confirms the depth of the tumour in the perimuscular connective tissue and the intraoperative frozen sections confirm microscopic negative margins. Likewise, for those whom gall bladder cancer was diagnosed from the pathological report after simple cholecystectomy, further hepatectomy may not necessary.

BACKGROUND: Recently for advanced gallbladder carcinoma, neoadjuvant chemotherapy has emerged as an important strategy in place of adjuvant chemotherapy with the hope that it will help to improve the resectability and survival. AIM AND OBJECTIVE: The goal was to conduct a systematic review of published publications on the benefits of neoadjuvant chemotherapy for advanced gallbladder cancer treatment. MATERIALS AND METHODS: This systematic review followed the Meta-analysis Of Observational Studies in Epidemiology standards. The clinical benefit rate of neoadjuvant chemotherapy, curative resectability rate, and R0 resection were the major outcomes of interest. The secondary outcomes of interest were overall and disease-free survival. RESULTS: Six published papers were included (n = 420). One-hundred and twenty-eight cases (30.47%) despite receiving neoadjuvant chemotherapy had disease progression. Although 67.38% of patients (283 of 420) in this systematic review showed good response to the neoadjuvant chemotherapy, just 51.66% (217 of 420 cases) were operated, out of which only 171 cases were deemed to be feasible for surgical resection and had curative resection. Out of the cases that underwent curative surgery, 91.81% had R0 resection (157 out of 171 patients). The overall survival rate was found to be 18.5-50.1 months for patients in whom curative surgery was done and 5.0-10.8 months for nonsurgery patients. CONCLUSION: No sufficient data exist to advocate the regular use of neoadjuvant chemotherapy in advanced gallbladder carcinoma, as data showed that only 1/3 of patients benefited and had a R0 resection. Further research should be the randomized controlled trials to further quantify the benefit of neoadjuvant chemotherapy in advanced gallbladder carcinoma.

RESUMO
BACKGROUND: Metastasis to lymph nodes is a bad prognostic factor in patients with gallbladder carcinoma who undergo radical cholecystectomy. During the past decade, studies have brought focus on lymph node ratio (LNR) as an additional valuable prognostic factor in these cases.Our research studied the factors that predicted the recurrence of disease and survival of patients with gallbladder carcinoma who were treated with surgical resection, concentrating especially on the lymph nodal status as a prognostic factor and LNR in node-positive T1-T3 cases. METHODS: In our hospital, Mahavir Cancer Institute and Research Centre, we reviewed retrospective data, from 2009 to 2014, of 60 patients who had undergone radical cholecystectomy for gallbladder carcinoma. We staged the patients as per the AJCC eight edition. Predictive factors that affect disease-free survival (DFS), like age, gender, postoperative complications, lymphovascular invasion (LVI) and perineural invasion (PVI), lymph node dissection, differentiation, T stage, N stage, number of lymph nodes involved, and LNR, were examined statistically. RESULTS: Lymph nodal involvement was found to be a principal predictive factor in cases in whom radical cholecystectomy was done. The number of lymph nodes dissected determined the prognosis in N0 cases. LNR was a strong prognostic factor for DFS in cases of curatively resected gallbladder cancer. CONCLUSION: LNR is a strong predictive factor in radically resected gallbladder carcinoma cases. HOW TO CITE THIS ARTICLE: Naveed S, Qari H, Thau CM, et al.

RESUMO
PURPOSE: It has been reported that there are left and right hepatic arterial arcades via the blood vessels around the hilar bile duct; therefore, when the hilar bile duct is preserved, hepatic artery reconstruction may not be necessary. We compared the short-term and long-term outcomes in patients with distal cholangiocarcinoma who underwent pancreatoduodenectomy (PD) with right hepatic artery resection without right hepatic artery reconstruction (RHAR group) with those patients who underwent conventional PD. METHODS: All data were retrospectively collected from patient records. A 1:4-propensity score-matched case-control study was conducted in patients with distal cholangiocarcinoma who received treatment at Tokyo Women's Medical University from February 1985 to April 2015. RESULTS: There was no statistical difference in the overall morbidity rate between the two groups. No patient in the RHAR group (10 patients) had liver failure, liver abscess, or cholangitis in the postoperative period; one patient died postoperatively because of a bleeding pseudoaneurysm in the gastroduodenal artery. The PD group (40 patients) had a significantly better median time regarding the recurrence (34 vs. 11 months, p=0.027) and 5-year disease-free survival (35% vs. 10%, p=0.027) rates than the RHAR group, which may be attributed to the presence of a more severe disease in patients in the RHAR group. CONCLUSION: We concluded that pancreaticoduodenectomy with right hepatic artery resection without reconstruction has a comparable overall morbidity rate with that of a conventional pancreaticoduodenectomy surgery and may be performed as an alternative procedure when tumor invasion of the right hepatic artery is suspected.

It is well known that surgery is the mainstay treatment for duodenal adenocarcinoma. However, the optimal extent of surgery is still under debate. We aimed to systematically review and perform a meta-analysis of limited resection (LR) and pancreatoduodenectomy for patients with duodenal adenocarcinoma. A systematic electronic database search of the literature was performed using PubMed and the Cochrane Library. All studies comparing LR and pancreatoduodenectomy for patients with duodenal adenocarcinoma were selected. Long-term overall survival was considered as the primary outcome, and perioperative morbidity and mortality as the secondary outcomes. Fifteen studies with a total of 3166 patients were analyzed; 995 and 1498 patients were treated with limited resection and pancreatoduodenectomy, respectively. Eight and 7 studies scored a low and intermediate risk of publication bias, respectively. The LR group had a more favorable result than the pancreatoduodenectomy group in overall morbidity (odd ratio [OR]: 0.33, 95% confidence interval [CI] 0.17-0.65) and postoperative pancreatic fistula (OR: 0.13, 95% CI 0.04-0.43). Mortality (OR: 0.96, 95% CI 0.70-1.33) and overall survival (OR: 0.61, 95% CI 0.33-1.13) were not significantly different between the two groups, although comparison of the two groups stratified by prognostic factors, such as T categories, was not possible due to a lack of detailed data. LR showed long-term outcomes equivalent to those of pancreatoduodenectomy, while the perioperative morbidity rates were lower. LR could be an option for selected duodenal adenocarcinoma patients with appropriate location or depth of invasion, although further studies are required.
