BACKGROUND: Warm autoimmune hemolytic anemia (w-AIHA) is an uncommon disease with heterogeneous response to treatment. Steroids are the standard treatment at diagnosis, whereas rituximab has recently been recommended as the second-line therapy of choice. Our main objective was to document the response to treatment in patients with newly diagnosed w-AIHA, including the effectiveness of low-dose rituximab as frontline treatment and for refractory disease. METHODS: Patients with w-AIHA from 2002 to 2017 were included. Relapse-free survival (RFS), probability of maintained response (MR), and time-to-response were analyzed using the Kaplan–Meier method. Response was classified as complete, partial, and no response. RESULTS: We included 64 adults with w-AIHA (39 women and 25 men). The median age was 37 (16–77) years. Response rates to steroids alone were 76.7%, rituximab plus steroids, 100%; and cyclophosphamide, 80%. RFS with steroids at 6, 36, and 72 months was 86.3%, 65.1%, and 59.7%, respectively. Eighteen patients received rituximab at 100 mg/wk for 4 weeks plus high-dose dexamethasone as first-line therapy, with RFS at 6, 36, and 72 months of 92.3%, 58.7% and 44.1%, respectively. Eight patients refractory to several lines of therapy were treated with low-dose rituximab, and all achieved a response (three complete response and five partial response) at a median 16 days (95% confidence interval, 14.1–17.8), with a 75% probability of MR at 103 months; the mean MR was 81.93±18 months. CONCLUSION: Outcomes of w-AIHA treatment were considerably heterogeneous. Low rituximab doses plus high dexamethasone doses were effective for refractory disease.

It is not a common case for neurosurgery department and the other departments to perform joint operation at the same time. Patients with severe head injury are a condition in which vital signs are unstable due to severe brain swelling and increased intracranial pressure, and emergency surgery is required. A 44-year-old man visited the trauma center with a motorcycle accident. The Glasgow Coma Scale score at the time of emergency department was 3 points, and the pupil was fixed at 6 mm on both sides. His medical history was unknown. His vital signs including blood pressure (BP), heart rate, respiratory rate and oxygen saturation were stable. Associated injuries included multiple fractures of whole body. Brain computed tomography revealed subarachnoid hemorrhage, intraventricular hemorrhage and severe cerebral edema. During the preparation of the craniectomy, abdominal ultrasonography performed because of decreased BP resulted in a large amount of hemoperitoneum. The bi-coronal craniectomy and splenectomy were performed simultaneously for about 4 hours. After fifty days of treatment, he was discharged with Glasgow Outcome Scale-extended 4 points and is undergoing rehabilitation. In severe polytrauma patients, active concurrent surgery is a good method to save their lives.

The function of the spleen in tumor development has been investigated for years. The relationship of the spleen with hepatocellular carcinoma (HCC), a huge health burden worldwide, however, remains unknown. The present study aimed to examine the effect of splenectomy on the development of HCC and the possible mechanism. Mouse hepatic carcinoma lines H22 and Hepa1-6 as well as BALB/c and C57 mice were used to establish orthotopic and metastatic mouse models of liver cancer. Mice were divided into four groups, including control group, splenectomy control group (S group), tumor group (T group) and tumor plus splenectomy group (T+S group). Tumor growth, metastases and overall survival were assessed at determined time points. Meanwhile, myeloid-derived suppressor cells (MDSCs) were isolated from the peripheral blood (PB), the spleen and liver tumors, and then measured by flow cytometery. It was found that liver cancer led to splenomegaly, and increased the percentage of MDSCs in the PB and spleen in the mouse models. Splenectomy inhibited the growth and progression of liver cancer and prolonged the overall survival time of orthotopic and metastatic models, which was accompanied by decreased proportion of MDSCs in the PB and tumors of liver cancer-bearing mouse. It was suggested that splenectomy could be considered an adjuvant therapy to treat liver cancer.

4.Precision lymphadenectomy for locally advanced gastric cancer.
Chinese Journal of Gastrointestinal Surgery 2016;19(2):138-143
Based upon studies from randomized clinical trials, the extended (D2) lymph node dissection is now recommended as a standard procedure for local advanced gastric cancer worldwide. However, the rational extent lymphadenectomy for local advanced gastric cancer has remained a topic of debate in the past decades. Patients with more lymph nodes harvested may have better survival. Negative node count may provide prognostic information for gastric cancer patients. The extranodal metastasis is significantly associated with the survival of gastric cancer patients and should be incorporated into N stage. In total gastrectomy for proximal gastric cancer without great curvature invasion, prophylactic splenectomy should be avoided not only for operative safety but also for survival benefit. The metastatic rate of No14v nodes for patients with distal stage III( disease is about 20%, so D2+ No.14v lymphadenectomy may be an option in a potentially curative gastrectomy for tumors with metastasis to the No.6 nodes. According to JCOG9501, extend D2+PAND should not be used to treat curable stage T2b, T3, N1-2 (II(B-III(A) gastric cancer. But the clinical benefit of D2+PAND for patients with stage T4 and/or stage N3 (III(B, III(C) disease could not be determined. The quality control of D2 procedure is very important for the prognosis of gastric cancer patients. Base on the experience from Europe, Unite States and China, centralization of gastric cancer treatment will improve the outcome of gastric cancer operation effectively.

Although the clinical benefit of laparoscopic splenectomy and devascularization (LSD) has been elaborated in many studies, its application in massive splenomegaly remains controversial. We conducted a retrospective research to assess the curative efficacy of LSD for massive splenomegaly due to portal hypertension. Forty-seven patients with massive splenomegaly due to portal hypertension were enrolled in this study, and divided into two groups. Twenty-one patients underwent open splenectomy and devascularization (OSD) from June 2010 to October 2012 (OSD group). From March 2013 to February 2015, LSD was performed on 26 patients (LSD group). Perioperative variables were analyzed. Compared to OSD, LSD was associated with less blood loss (241.9±110.0 mL vs. 319.0±139.5 mL, P<0.05), more rapid resumption of oral diet (2.46±0.95 days vs. 3.76±1.09 days, P<0.05), and shorter postoperative hospital stay (5.35±1.65 days vs. 7.24±1.55 days, P<0.05). It was concluded that for patients with massive splenomegaly due to portal hypertension, LSD is feasible and as safe as OSD.

Sclerosing angiomatoid nodular transformation (SANT) is an exceedingly rare, benign and proliferative vascular lesion that arises from the splenic red pulp. It is often an incidental finding on imaging. The diagnosis of SANT is confirmed via histopathological examination of the resected spleen. Herein, we present a case of SANT and describe its typical imaging characteristics. An asymptomatic 39-year-old man was found to have a 3.1 cm × 2.7 cm × 2.3 cm hypoechoic splenic lesion during abdominal ultrasonography, which was performed to investigate his elevated gamma-glutamyl transpeptidase and alanine transaminase levels. Contrast-enhanced computed tomography suggested a vascular splenic lesion, while magnetic resonance imaging demonstrated features consistent with SANT. In view of the increasing size of the lesion on follow-up imaging, the patient elected for splenectomy. Histopathological examination confirmed SANT, and the lesion was completely resected by laparoscopic splenectomy.

BACKGROUNDSurgical treatment has become the standard treatment for nontraumatic diseases of the spleen. This meta-analysis compared the relative merits of laparoscopic splenectomy (LS) with open splenectomy (OS) for nontraumatic splenic diseases.
METHODSA literature search was performed to identify studies comparing perioperative outcomes in patients who underwent LS or OS for nontraumatic diseases. Pooled odds ratios (ORs) and weighted mean differences (WMD) with 95% confidence intervals (CIs) were calculated using a fixed- or random-effects model.
RESULTSThirty-five studies matched the selection criteria. Of the 7 269 patients included 3 981 underwent LS and 3 288 underwent OS for nontraumatic diseases. OS was associated with shorter operation time (WMD = 42.65, 95% CI: 25.58-59.73), whereas LS was associated with reduced operative blood loss (WMD = -133.95, 95% CI: -229.02 to -38.88), need for blood transfusion requirement (OR = 0.53, 95% CI: 0.39-0.72), overall postoperative morbidity rate (OR = 0.44, 95% CI: 0.38-0.51), postoperative mortality rate (OR = 0.38, 95% CI: 0.24-0.59), and length of hospital stay (WMD = -2.73, 95% CI: -3.34 to -2.12).
CONCLUSIONSLS is superior to OS for nontraumatic diseases, with reduced operative blood loss, need for blood transfusion, postoperative morbidity and mortality rates, and length of hospital stay, although OS is associated with reduced operation time. LS may be a good alternative to OS for patients with nontraumatic splenic diseases.

Journal of Minimally Invasive Surgery 2013;16(4):91-97
PURPOSE: Laparoscopic splenectomy (LS) is one method for treatment of various diseases of the spleen, especially hematological conditions. However, few recent long-term follow-up results have been reported. The purpose of this study is to evaluate the outcome of patients in a single institution who recently underwent LS and to analyze their long-term follow-up results. METHODS: Of 366 splenectomies, this study was conducted as a retrospective review of 52 patients who underwent LS for treatm ent of hematological or primary diseases of the spleen from January 1998 to October 2011. The data included age, sex, pathological diagnosis, operative time, postoperative hospital stay, rate to open conversion, perioperative transfusion, morbidity, mortality, and relapse. We analyzed outcomes of variable results through long-term follow-up. RESULTS: The mean follow-up period was 84 months (range, 4~147 months). The most common indication for LS was immune thrombocytopenic purpura (ITP). The median postoperative hospital stay was eight days (range, 3~28 days). Mean operative time was 203 minutes (range, 115~475 minutes). Two patients underwent open conversion. Thirty eight patients received perioperative transfusions. The mean spleen weight was 294.9 g (range, 31~2,564 g). The overall morbidity rate was 5.8% and one patient experienced relapse. Of the 28 patients with ITP, 89.3% responded to LS. CONCLUSION: LS should be one of the best treatment options regardless of splenomegaly and spleen-associated diseases. In particular, for patients with ITP, LS has shown very effective long-term follow-up results. Therefore, LS should be more actively considered as an early treatment option in surgical disease of the spleen, such as ITP.

OBJECTIVE:
To evaluate the surgical outcomes of laparoscopic splenectomy and to investigate the learning curve of laparoscopic splenectomy.
METHODS:
Forty cases of laparoscopic splenectomy (performed by W.Y. between September 2008 and August 2010) in our general surgery department were reviewed, and the cases were divided equally into 4 groups (group I, II, III, IV) according the time sequence of the operations. The operating time, blood loss, conversion to open surgery, conversion to hand-assisted laparoscopic splenectomy, postoperative hospital stay, postoperative liquid diet recovery time, intra- and postoperative complications and the operative frequency were compared.
RESULTS:
There were no statistical differences among the groups in age and gender (P>0.05). The operating time, blood loss and postoperative hospital stay of groups III and IV were significantly less than those of groups I and II (P<0 .05). Postoperative liquid diet recovery time appear to show a gradual shortening trend from Group I to Group IV, but the differences were not at standard statistical thresholds (P>0.05). Frequency of conversion to open surgery, of conversion to hand-assisted laparoscopic splenectomy, of complications among the four groups were also not statistically different (P>0.05). The operative frequency of group I-IV increased from 1.25/month to 2.5/month.
CONCLUSION
The learning curve of laparoscopic splenectomy for surgeon who was experienced in open splenectomy and laparoscope cholecystectomy is approximately 20 cases, and the operative frequency is about 1.33/month.
