ABSTRACT
BACKGROUND AND OBJECTIVES: This study aimed to assess the effectiveness of Comprehensive Geriatric Assessment (CGA) in customizing care for elderly cancer patients, specifically focusing on colorectal cancer. The research compared treatment strategies and outcomes in older adults considered for surgery before and after the initiation of a Geriatric Oncology Service (GOS). METHODS: Conducting a comparative study, two cohorts of consecutive colorectal cancer patients aged 75 or older were examined: the control group (n = 156) and the GOS group (n = 158). Upon the treating surgeon's GOS consultation request, a geriatrician and an oncologist performed CGA, guiding treatment decisions and perioperative interventions. Postoperative complications were compared using propensity score matching (PSM). RESULTS: In the GOS group, 91% (n = 116) underwent CGA consultations, influencing decisions to forego surgery in 12 patients. After PSM for surgical cases (controls n = 146, GOS n = 146), each group comprised 128 patients. Perioperative physical therapy and pharmacist referrals were more frequent in the GOS group. The GOS group exhibited a significantly lower incidence of postoperative complications (22%) compared to the control group (33%) (p = 0.0496). CONCLUSION: Patients undergoing colorectal surgery post-GOS implementation experienced a notable reduction in postoperative complications, highlighting the positive impact of personalized geriatric assessment on surgical outcomes in the elderly.

BACKGROUND: Portal vein thrombosis (PVT) and venous thromboembolism (VTE) both result from partial or complete occlusion of a blood vessel by a blood clot. The prognosis of PVT is generally good; however, PVT with VTE, including pulmonary embolism (PE), has a high mortality rate. We report here a case of PE after surgery for small intestinal necrosis caused by idiopathic PVT. CASE PRESENTATION: A 69-year-old female attended our hospital with a chief complaint of upper abdominal discomfort, and was diagnosed with necrosis of the small intestine as a result of unexplained PVT. She underwent partial resection of the small intestine. On the second postoperative day, she suffered from respiratory distress and went into cardiopulmonary arrest. The patient recovered following cardiopulmonary resuscitation, but PE was detected. Extracorporeal veno-arterial cardiopulmonary resuscitation and anticoagulation therapy were initiated immediately and the thrombus was aspirated as much as possible. Two days later, extracorporeal veno-arterial cardiopulmonary resuscitation was withdrawn and anticoagulation therapy was continued. The patient subsequently recovered with no neurological damage and was discharged on day 26 after the above procedure. CONCLUSIONS: Idiopathic PVT is often associated with VTE, and a prompt diagnosis and intervention may result in a good prognosis.
ABSTRACT
BACKGROUND: Gastrectomy with D2 dissection and adjuvant chemotherapy is the standard treatment for locally advanced gastric cancer (LAGC) in Asia. However, administering chemotherapy with sufficient intensity after gastrectomy is challenging. Several trials demonstrated the efficacy of neoadjuvant chemotherapy (NAC). However, limited studies explored the feasibility of NAC-SOX for older patients with LAGC. This phase II study (KSCC1801) evaluated the safety and efficacy of NAC-SOX in patients with LAGC aged ≥ 70 years. METHODS: Patients received three cycles of SOX130 (oxaliplatin 130 mg/m2 on day 1, oral S-1 40-60 mg twice daily for two weeks every three weeks) as NAC, followed by gastrectomy with lymph node dissection. The primary endpoint was the dose intensity (DI). The secondary endpoints were safety, R0 resection rate, pathological response rate (pRR), overall survival, and relapse-free survival. RESULTS: The median age of 26 enrolled patients was 74.5 years. The median DI in NAC-SOX130 was 97.2% for S-1 and 98.3% for oxaliplatin. Three cycles of NAC were administered in 25 patients (96.2%), of whom 24 (92.3%) underwent gastrectomy with lymphadenectomy. The R0 resection rate was 92.3% and the pRR (≥ grade 1b) was 62.5%. The major adverse events (≥ grade 3) were neutropenia (20.0%), thrombocytopenia (11.5%), anorexia (11.5%), nausea (7.7%), and hyponatremia (7.7%). Postoperative complications of abdominal infection, elevated blood amylase, and bacteremia occurred in one patient each. Severe diarrhea and dehydration caused one treatment-related death. CONCLUSIONS: NAC-SOX130 is a feasible therapy for older patients, although systemic management and careful monitoring of adverse events are necessary.

BACKGROUND AND AIM: This study aimed to clarify the prognostic value of various inflammation-based prognostic scores (IBPSs) in patients who underwent radical surgery for colorectal cancer (CRC) and to develop a novel prognostic index using IBPSs and other predictive factors. METHODS: Data of 1157 patients who underwent radical surgery for CRC were reviewed. The predictive value of various IBPSs in determining the CRC prognosis was compared. A novel index score based on the IBPSs and other parameters that were associated with survival in patients with CRC was established, and its usefulness was evaluated. RESULTS: The patients were randomly divided into the training (n = 694) and validation (n = 463) sets. Male sex (P = 0.0001), age ≥ 75 years (P < 0.0001), a carcinoembryonic antigen (CEA) level of > 5 (P = 0.0009), a C-reactive protein/albumin ratio (CAR) of ≥ 0.04 (P = 0.0033), and a prognostic nutritional index (PNI) of < 43.1 (P = 0.0004) were poor independent prognostic factors of overall survival. The novel index score was calculated based on the scores of these five prognostic factors. The Kaplan-Meier survival curves showed that the CRC patients with higher novel index scores in the training and validation datasets had poorer overall survival. CONCLUSIONS: CAR and PNI were superior to other IBPSs for predicting the prognosis of CRC patients. The novel index score established based on sex, age, CEA level, CAR, and PNI can predict the prognosis of CRC with more precise and clearer stratification than the individual parameters alone.

Background: This study aimed to clarify the safety and efficacy of laparoscopic surgery for colorectal perforation by comparing the clinical outcomes between laparoscopic and open emergency surgery for colorectal perforation. Materials and Methods: We retrospectively reviewed the data of 116 patients who underwent surgery for colorectal perforation. The patients were categorized into two groups: the open group included patients who underwent laparotomy, and the laparoscopic group included those who underwent laparoscopic surgery. Clinical and operative characteristics and postoperative outcomes were evaluated. Results: The open and laparoscopic groups included 67 and 49 patients, respectively. More than half of the patients in both groups developed perforation in the sigmoid colon (open, 58.2%; laparoscopic, 61.2%). The most common cause of perforation was diverticulum, followed by colorectal cancer. The mean intraoperative blood loss was significantly lower in the laparoscopic group than in the open group (70.0 mL versus 160.3 mL; P = .0290). The incidence of surgical site infection was lower in the laparoscopic group than in the open group (2.0% versus 13.4%; P = .0430). There were no significant differences in either the short- or long-term outcomes between the two groups. Univariate and multivariate analyses showed that the choice of surgical approach (open versus laparoscopic) did not affect overall survival in patients with colorectal perforation. Conclusion: The laparoscopic approach for colorectal perforation in an emergency setting can be safely performed and provides certain advantages over an open approach in suitable patients.

BACKGROUND/AIM: Surgery for elderly patients with gastric cancer is becoming more common. However, the risk factors of the laparoscopic surgery for these patients are unknown, and thus it is difficult to determine appropriate treatments for such patients. The aim of this retrospective study was to clarify the risk factors for the treatment outcomes after laparoscopic gastrectomy in elderly patients. PATIENTS AND METHODS: Two hundred twenty-two patients who underwent laparoscopic gastrectomy for primary gastric cancer between January 2014 and December 2017 were enrolled. Clinical characteristics and short- and long-term prognoses were analyzed in 47 patients aged 75 years or older (elderly group) and in 175 patients who were under 75 years old (non-elderly group). RESULTS: The presence of comorbidities was more common in the elderly group than in the non-elderly group (91.5% vs. 61.7%, p<0.0001). The rate of postoperative complications in the elderly group was significantly higher than that in the non-elderly group (42.6% vs. 22.9%, p=0.01). The 5-year overall survival rate was significantly lower in the elderly group than in the non-elderly group (66.9% vs. 92.2%; p<0.0001). In the elderly group, 5-year overall survival in patients with a low preoperative prognostic nutritional index (PNI) was significantly worse than that in patients with a high preoperative PNI (25.0% vs. 80.9%; p<0.05). Multivariate analysis showed that the PNI value was independently associated with overall survival in elderly patients who underwent laparoscopic gastrectomy (p<0.05). In particular, the rate of non-cancer deaths after surgery in elderly patients was significantly higher than that in non-elderly patients (p<0.05). CONCLUSION: PNI value is an independent prognostic factor for overall survival in elderly patients who have undergone laparoscopic gastrectomy for gastric cancer; therefore, in elderly patients with low preoperative PNI, attention should be paid not only to recurrence of cancer, but also to the deterioration of general condition caused by malnutrition.

Aim: Oxaliplatin, an anticancer drug for advanced colorectal cancer, causes liver sinusoidal damage, sometimes with portal hypertension. We conducted a retrospective comparative study of the relationship of liver sinusoidal disorders and liver function with the prognosis in patients who underwent hepatectomy for colorectal liver metastasis (CRLM). Methods: In total, 158 patients who underwent hepatectomy for CRLM were included in the study, and the effect of chemotherapy-associated liver damage on the prognosis was examined. Results: Preoperative oxaliplatin was used in 75 of 158 patients; of these 75 patients, 26 had intraoperative blue liver (BL). In a comparison of the BL group (n = 26) and non-BL group (n = 132), patients in the BL group had a significantly lower serum albumin concentration and a significantly higher indocyanine green test result, aspartate aminotransferase-to-platelet ratio index (APRI), and FIB-4 score. Operative morbidities were not significantly different between the two groups. The overall survival rate after hepatectomy was significantly worse in the BL group than in the non-BL group. In the univariate analysis, the serum albumin concentration, indocyanine green test, a high tumor burden score (TBS), and the APRI were statistically significant poor prognostic factors. In the multivariate analysis, the APRI and a high TBS were independent poor prognostic factors. Conclusion: The APRI and TBS in patients with CRLM are prognostic predictors after hepatectomy for metastatic liver cancer. This study indicated that liver damage in patients treated with preoperative oxaliplatin has an effect on the prognosis.
ABSTRACT
PURPOSE: Selected patients with initially unresectable colorectal cancer (CRC) and liver metastases undergo conversion surgery after appropriate chemotherapy. The prognosis of these patients is good, with some even cured of the disease. This retrospective, single-institution study analyzes the clinical importance of patient characteristics on the outcomes of conversion hepatectomy. METHODS: We evaluated 229 consecutive patients with initially unresectable CRC and liver metastasis, who underwent systemic chemotherapy. The patients were assigned to groups depending on conversion hepatectomy. RESULTS: Conversion hepatectomy was performed in 30 patients (13.1%). The proportion of patients with extrahepatic metastasis was significantly lower in the conversion group than in the unresectable group (30.0 vs. 66.8%; P < 0.01). The rate of left-sided primary colorectal tumors was significantly higher in the conversion group than in the unresectable group (96.7 vs. 65.8%; P < 0.01). Multivariate analyses identified that left-sided tumors, no extrahepatic metastasis, H1 or H2 grade CLM, and treatment with molecular-targeted agents were associated with conversion hepatectomy (odds ratios: 16.314, 4.216, 7.631, and 4.070; P < 0.01). Overall survival was significantly longer in the conversion group than in the unresectable group (MST: 50.0 versus 14.7 months; P < 0.01). CONCLUSION: Left-sided primary tumors, absence of extrahepatic metastases, H1 or H2 grade, and use of molecular-targeted agents were associated with successful conversion hepatectomy; thus, patients with these characteristics may be candidates for conversion therapy.

BACKGROUND: Compared with open standard gastrectomy (OG), laparoscopic gastrectomy (LG) did not result in inferior disease-free survival for early-stage and locally advanced gastric cancer (AGC). However, whether LG for AGC in elderly patients is more beneficial than OG is unclear. METHODS: This study examined 458 patients with AGC. The mortality, morbidity, and prognosis were compared by age, gender, T and N factors, and pathological stage in the LG and OG groups using propensity score matching analysis. For the final analysis, 151 pairs of patients were selected from at each group. RESULTS: The results showed that no significant difference in mortality and morbidity existed between the two groups. The 5-year relapse-free survival (RFS) rates were 70% and 62% in the LG and OG groups, respectively (p = 0.104). The 5-year RFS rates in patients with pathological stages I, II, and III who had undergone LG were 84%, 80%, and 55%, respectively, and 78%, 70%, and 45%, respectively, in those who had undergone OG (p < 0.005). The 5-year RFS rates in nonelderly patients who underwent LG or OG were 75% and 68%, respectively, and 58% and 40%, respectively, in elderly patients who underwent LG or OG (p < 0.005). CONCLUSION: The 5-year RFS rates in patients with AGC at each stage did not significantly differ between LG and OG. However, the benefits at 5-year RFS in patients who underwent LG compared with OG were larger in elderly patients than those in nonelderly patients.

Esophageal cancer is one of the malignant tumors with the poorest prognosis. Esophagectomy, which is the mainstay of curative-intent treatments, imposes excessive surgical stress on the patients, and postoperative morbidity and mortality rates after esophagectomy remain high. On the other hand, the number of survivors after esophagectomy for esophageal cancer is increasing due to recent improvements in surgical techniques and multidisciplinary treatments for this cancer. However, esophagectomy still has a great influence on the fundamental aspect of patients' lives, that is, the health-related quality of life (HR-QOL), including their physical, emotional, and social functions in the short- and long-term postoperatively. HR-QOL is a multifactorial concept used to assess the symptoms and functional changes caused by the disease itself and treatments from the patients' perspectives. Therefore, assessing the HR-QOL of patients with esophageal cancer after esophagectomy is becoming increasingly important. However, the status of HR-QOL changes after esophagectomy has not been satisfactorily evaluated, and there is no worldwide consensus as to how the postoperative HR-QOL can be improved. This review aimed to raise awareness of healthcare providers, such as surgeons and nurses, on the importance of HR-QOL in patients with esophageal cancer after curative-intent esophagectomy by providing multifaceted information concerning the short- and long-term HR-QOLs, including the status of changes and the determinants of HR-QOL after esophagectomy, and furthermore, essential points for improvement of HR-QOL after esophagectomy.

BACKGROUND: Intraductal papillary mucinous neoplasm (IPMN) can lead, via the adenoma-carcinoma sequence, to invasive adenocarcinoma, which has a poor prognosis. Most IPMNs do not meet the indications for surgery and instead are monitored regularly, but no biomarkers of malignant transformation during surveillance have been established. PATIENTS AND METHODS: A total of 50 patients with IPMN who underwent pancreatectomy were evaluated retrospectively. Clinicopathological parameters during the surveillance period before surgery were assessed to explore biomarkers for predicting malignancy. RESULTS: The serum level of carbohydrate antigen 19-9 was significantly higher in IPMN-derived invasive adenocarcinoma. The neutrophil-to-lymphocyte ratio was significantly lower in low-grade IPMN than high-grade and Inv-IPMN cases by univariate and multivariate analysis. Disease-free survival was significantly shorter in patients with high-grade and invasive IPMN compared with those with low-grade IPMN. In patients whose preoperative surveillance was performed for more than 12 months, the neutrophil-to-lymphocyte ratio was significantly higher in those with high-grade and invasive IPMNs compared with patients with low-grade IPMN in the year before surgery. CONCLUSION: The NLR is a useful biomarker for distinguishing between low-grade and high-grade IPMN and thus should be monitored during surveillance.

BACKGROUND: In laparoscopic gastrointestinal surgery, the location of the tumor is identified mainly with marking methods, such as ink tattooing and intraoperative gastrointestinal endoscopy and marking with a metal clip followed by confirmation with intraoperative x-ray fluoroscopy. Each method has disadvantages, such as complexity, instability of ink sticks, and radiation exposure. Thus, a simple and less-invasive marking method is needed. METHODS: We developed a wireless light-emitting marker with a miniature light-emitting diode that uses a magnetic field resonance mechanism. It emits 4 individual colors-red, blue, green, and white. We confirmed the usefulness of this marker system in ex vivo and in vivo animal experiments. RESULTS: In the ex vivo experiment in porcine intestines, use of the wireless marker was successful, as each color of emitted light was recognized from outside the intestine. In the live animal experiment, it was confirmed that the light emitted by the marker system was visible in the porcine intestinal tract during laparoscopic surgery. The light emitted by the wireless marker in the intestinal tract was confirmed with a laparoscope in a simulated animal surgery. CONCLUSION: We have developed an innovative, radiation-free and reliable light-emitting marker system that uses a magnetic field resonance mechanism that emits four colors of light during laparoscopic surgery.

BACKGROUND: Ectopic variceal bleeding is a rare but life-threatening complication of portal hypertension (PH). Oxaliplatin-based chemotherapy for colorectal cancer (CRC) is associated with sinusoidal obstruction syndrome of the liver, which can lead to PH. CASE PRESENTATION: Here, we report a successful hybrid surgery that included intraoperative obliteration of ileal conduit stomal varices (ICSVs) for a 66-year-old woman with CRC and liver metastasis that had been treated multimodally during the previous 4 years, including 17 courses of oxaliplatin-based chemotherapy. She was admitted to our hospital for massive hemorrhage from an ileal conduct stoma. Image findings showed ICSVs as a part of portosystemic shunt, which were afferently supplied from the superior mesenteric vein (SMV) and drained by the numerous cutaneous veins connected to the left femoral vein. Obliteration of the stomal varices by interventional radiologic techniques alone was inappropriate because of difficulties of cannulating the efferent cutaneous veins. We, therefore, performed hybrid surgery for the ICSV, which included cannulation into the SMV branch and antegrade obliteration of the varices with a 5% solution of ethanolamine oleate with iopamidol under blocking the SMV flow, using a vascular clip and ligation. Hemorrhage in her ileal conduit stoma disappeared completely. CONCLUSION: Customized treatment of ectopic varices should be based on their precise vascular anatomy; hybrid surgery with intraoperative angiography is an alternative treatment for ectopic varices such as ICSV.
ABSTRACT
Esophageal bypass surgery is an effective treatment strategy for esophageal cancer with esophago-tracheobronchial fistula. We herein report an esophageal cancer patient with esophago-pulmonary fistula who achieved a long-term survival but died suddenly because of cardiac tamponade. A 70-year-old male patient with esophago-pulmonary fistula due to esophageal tumor invasion underwent definitive chemoradiotherapy as the initial treatment. Esophageal bypass surgery followed by additional chemotherapy was performed, and the patient survived for a long time. Four years and six months later, a small abscess in an esophago-pulmonary fistula was visualized on computed tomography. One month later, he suffered suddenly severe dyspnea and died. An autopsy suggested that the direct cause of death had been cardiac tamponade due to atrio-pericardial fistula. Definitive therapy for esophageal cancer with fistula after esophageal bypass is an effective treatment, but close special attention must be paid to the possibility of irradiation-related late toxicity.

BACKGROUND/AIM: The safety and efficacy of laparoscopic total gastrectomy (LTG) for remnant gastric cancer (RGC) remains unclear. The purpose of this study was to compare the clinical outcomes of LTG with open total gastrectomy (OTG) for RGC. PATIENTS AND METHODS: Twenty-two patients who underwent total gastrectomy for RGC were enrolled in this study. RESULTS: LTG was carried out in seven patients, and OTG was performed in the remaining 15 patients. The mean operation time in the LTG group was longer than that in the OTG group. The estimated blood loss in the LTG group was less than that in the OTG group. No cases in the LTG group required open conversion. Postoperatively, the first meal and defecation were earlier in the LTG group than in the OTG group. The overall survival rates of the two groups were comparable. CONCLUSION: Laparoscopic total gastrectomy is a feasible surgical option for RGC.

BACKGROUND/AIM: Pancreatic surgery is associated with a high risk of developing deep venous thrombosis (DVT) and malnutrition. We aimed to evaluate the factors predicting the development of DVT, focusing on nutrition assessment tools. PATIENTS AND METHODS: One hundred patients who underwent pancreatic surgery were postoperatively examined for DVT. We assessed the risk factors for the development of DVT after surgery. RESULTS: Postoperative DVT was detected in 11 patients (11%). Patients who developed DVT after surgery were significantly older (p=0.016) and had higher preoperative D-dimer levels (p=0.005) than those who did not. The preoperative prognostic nutritional index (PNI) was mostly associated with the development of DVT (p=0.079). Furthermore, PNI ≤44.3, BUN >20 mg/dl, D-dimer ≥1.9 µg/ml were independent predictors for the development of DVT after surgery. CONCLUSION: A poor nutrition status and dehydration should be preoperatively improved for patients who are identified, as having a high risk of developing DVT after pancreatic surgery.

BACKGROUND: Neuroendocrine carcinoma (NEC) of the esophagus and the stomach is aggressive. The purpose of this study was to determine the optimal therapeutic strategy. METHODS: Both clinicopathological factors and treatment results were examined in 34 patients with immunohistochemically diagnosed NEC of the upper gastrointestinal tract (esophagus 22; stomach 12). RESULTS: Twenty-nine tumors showed protruding and localized type, like submucosal tumor. Esophagectomy and gastrectomy were performed in six and eight patients, respectively. Among the six patients with esophageal NEC, three with node metastasis developed recurrence within seven months, while the other three (pT1bN0) had no recurrence. Regarding gastric NEC, three patients with pT3N1 or 2 tumor received adjuvant chemotherapy and achieved a 5-year survival. However, the other five experienced recurrence after gastrectomy. Systemic chemotherapy was performed as the main treatment for 18 patients with advanced NEC. The median survival was 10 months after initial chemotherapy. No marked differences in the response were recognized between the 14 cases with esophageal NEC and the 4 with gastric NEC. The median survival was 14.3 and 5.3 months for the 11 effective and 7 non-effective patients, respectively. CONCLUSIONS: A macroscopically unique appearance, like submucosal tumor, suggests the possibility of NEC. Esophagectomy is an effective treatment option for limited-stage NEC without node metastasis, while gastrectomy followed by adjuvant chemotherapy may be effective for NEC even with node metastasis when R0 resection can be achieved. Systemic chemotherapy is relatively effective for advanced NEC, although early progression frequently develops.

BACKGROUND/AIM: The aim of this study was to determine the significance of immunonutritional and physical index in the assessment of risk associated with pancreaticoduodenectomy (PD) in the elderly. PATIENTS AND METHODS: This study enrolled 92 patients who underwent PD. They were divided into 2 groups: Group A included patients 79 years and younger (n=79) and Group B patients 80 years and older (n=13). Among 37 patients, physical function and body composition were also evaluated. RESULTS: Significantly higher neutrophil-lymphocyte ratio, lower prognostic nutritional index (PNI), and controlling nutritional score were observed in Group B. Muscle strength and walking ability were significantly impaired in Group B, although there was no significant difference in body composition. Age was not correlated with the incidence of postoperative complications, overall survival or recurrence-free survival by univariate and multivariate analysis. CONCLUSION: PD is justified for the elderly, with acceptable morbidity and prognosis. However, immunonutritional status and physical function are significantly impaired; thus, appropriate case selection and active nutritional support are required for the elderly.

Portal vein thrombosis (PVT) is considered to be a frequent complication of liver cirrhosis. However, unlike PVT in patients without cirrhosis, very few data are available on the natural history and management of PVT in cirrhosis, despite its association with potentially life-threatening conditions, such as gastroesophageal bleeding and acute intestinal ischemia. Moreover, no consensus regarding PVT in cirrhosis exists. Suggested causes of PVT in cirrhosis include reduced portal blood flow velocity, multiple congenital or acquired thrombophilic factors, inherited or acquired conditions, and derangement of liver architecture. However, the understanding of PVT in cirrhosis is incomplete. In addition, information on the management of PVT in cirrhosis is inadequate. The aims of this review are to: (1) assemble data on the physiopathological mechanism, clinical findings, diagnosis and management of PVT in cirrhosis; (2) describe the principal factors most frequently involved in PVT development; and (3) summarize the recent knowledge concerning diagnostic and therapeutic procedures.
ABSTRACT
INTRODUCTION: Laparoscopic devascularization of the upper stomach and splenectomy (Dev+Sp), is technically difficult in patients with portal hypertension because of enlarged collateral vessels and spleen. This report presents the efficacy and safety of hand-assisted laparoscopic (HALS) Dev+Sp. METHODS: Ten patients underwent HALS Dev+Sp as a treatment for esophagogastric varices between 2005 and 2012 (HALS group). A vessel-sealing system was used for devascularization of vessels. An autosuture device was applied to dissect the splenic hilum and the left gastric and enlarged short gastric vessels. The operative and postoperative data were compared between patients who previously underwent laparoscopic Dev+Sp (LAP group, n = 9) and conventional Dev+Sp (OP group, n = 10) between 2001 and 2008. RESULTS: The mean operative time was 328, 336, and 245 min (P < 0.05) and the mean blood loss was 1786, 981, and 250 mL (P < 0.05) in the OP, LAP, and HALS groups, respectively. Laparoscopic surgery was converted to HALS in one patient and to open surgery in three patients. There were no conversions in the HALS group. There was no significant difference in the cumulative recurrence rate and bleeding rate in the groups. CONCLUSION: HALS Dev+Sp is a feasible and effective surgery in patients with portal hypertension.
