RESUMO
BACKGROUND/AIM: This study aimed to evaluate the clinical impact of the level of inferior mesenteric artery (IMA) ligation in patients with advanced low rectal cancer. PATIENTS AND METHODS: All enrolled patients (n=350) underwent curative resection of rectal cancer with D3 lymph node dissection, with either IMA (high-tie) or superior rectal artery (SRA) (low-tie) ligation. RESULTS: There were 27 and 65 patients in the high-tie and low-tie groups, respectively. There was no significant difference in the postoperative complication rate. Postoperative anastomotic leakage developed in five patients in the low-tie group and none in the high-tie group. The overall recurrence rates were 37.0% (n=10) and 40.0% (n=26) in the high-tie and low-tie groups, respectively, with no significant difference between the two groups (p=0.748). Local recurrences and lymph node metastases developed in five and no patients in the high-tie group and in 13 and one patient in the low-tie group, respectively. In the multivariate analysis, pathological T4 and pathological N2 and N3 were independent poor prognostic factors for overall survival (OS), whereas left colic artery (LCA) preservation was not significant. CONCLUSION: No significant difference in oncological outcomes was observed in advanced low rectal cancer surgery with respect to the level of the IMA ligation. Thus, the less complicated high-tie procedure should be adopted as a standard procedure.

BACKGROUND: Laparoscopic surgical approaches, including total extraperitoneal repair (TEP), have been widely accepted for inguinal hernia repair in Japan. However, there are limited data regarding recurrence after TEP in Japan, given the limited versatility of this procedure. This study retrospectively evaluated the rates of hernia recurrence after TEP and open mesh repair at multiple Japanese centers. METHODS: This retrospective study evaluated 1917 patients who underwent inguinal hernia repair at 32 institutions in the Oita prefecture between January 2014 and December 2015. Eligible patients were grouped according to whether they underwent TEP (1011 patients) or open mesh repair (636 patients). Propensity score matching was performed 1:1 (total: 1076 patients, 538 patients from each group). The outcomes of interest were recurrence, morbidity, and postoperative recovery. RESULTS: The TEP and open mesh repair groups had similar baseline characteristics. After propensity score matching, there was no significant difference between the two groups in terms of recurrence rate (TEP: 0.5% vs open mesh repair: 1.0%, P = .375). However, the TEP group had significantly longer operating times (median: 70.2 min vs 65.0 min, P < .001), significantly less blood loss (0-5.1 mL vs 0-20.4 mL, P < .001), and significantly shorter postoperative hospital stays (median: 5.0 days vs 6.4 days, P < .001). The overall incidences of morbidity were 6.2% in the TEP group and 7.2% in the open mesh repair group (P = .535). CONCLUSION: This multicenter retrospective study with propensity score matching revealed that the recurrence rates were similarly low for TEP and open mesh repair of inguinal hernia. Thus, a well-trained surgical team could use TEP as a standard procedure.
RESUMO
AIM: Sarcopenia has been reported as a prognostic predictor in various conditions; however, it has not been examined in patients with perforation panperitonitis. METHODS: A total of 103 consecutive patients with perforation panperitonitis who underwent emergency surgery from 2008 to 2016 were retrospectively evaluated. Skeletal muscle index (SMI) was measured as the cross-sectional area (cm2) of skeletal muscle in the L3 region on computed tomography images normalized for height (cm2/m2). Sarcopenia was defined as an SMI of ≤43.75 and ≤41.10 cm2/m2 in men and women, respectively. The impact of sarcopenia on postoperative outcomes was investigated. RESULTS: Sarcopenia was present in 50 (48.5%) patients. Severe complications (Clavien-Dindo grade ≥IIIb) and in-hospital mortality were more frequently observed in patients with than without sarcopenia (28.0% vs 9.4%, P = .015) (20.0% vs 5.7%, P = .029) respectively. Multivariate analysis showed that age, sarcopenia, and renal dysfunction were independent risk factors for severe complications and in-hospital mortality. The optimal cut-off levels of age and SMI for predicting these were ≥79 years and SMI <38 cm2/m2, respectively. Among the patients aged ≥79 years, those with SMI <38 cm2/m2 had a severe complication rate of 71% and an in-hospital mortality rate of 57%, whereas the rate of those with SMI ≥38 cm2/m2 was 22% (P = .011) and 11% (P = .008), respectively. CONCLUSION: Sarcopenia is a predictive factor of severe complications and in-hospital mortality following emergency surgery for perforation panperitonitis, especially in elderly patients. Estimation of sarcopenia may identify patients eligible or not eligible for emergency surgery among elderly patients.
RESUMO
BACKGROUND: Blood flow of the remnant stomach is supplied via the right gastric and right gastroepiploic vessels after proximal gastrectomy (PG). Whether the remnant stomach can be safely preserved in patients who undergo pylorus-preserving pancreatoduodenectomy (PPPD) after PG remains unclear. We herein report two cases in which the remnant stomach was safely preserved by performing PPPD. CASE PRESENTATION: The first patient, a 76-year-old man, was diagnosed with cancer of the common bile duct and underwent PPPD 2 years after PG for gastric cancer. The remnant stomach and right gastroepiploic vessels were safely preserved. The second patient, a 56-year-old man with a history of PG for gastric cancer 20 years previously, was diagnosed with cancer of the common bile duct and underwent PPPD. We could safely preserve the remnant stomach and right gastroepiploic vessels. CONCLUSION: The remnant stomach could be preserved in performing PPPD following PG by preserving the right gastroepiploic vessels.
RESUMO
BACKGROUND: Plexiform fibromyxoma (PF) is a rare gastric mesenchymal tumor, with approximately 80 cases reported to date. Gastrointestinal stromal tumor, the most common primary mesenchymal tumor of the stomach, shows different biological and clinical characteristics between adult and pediatric patients. OBJECTIVES: This systematic literature review was conducted to elucidate the pathological and clinical features of pediatric PF compared to adult PF. METHODS: MEDLINE (1948 to March 2018) and EMBASE (1947 to March 2018) were searched, and all English articles that reported clinical data on PF patients were identified. Two authors independently reviewed the articles and extracted data to assess immunohistochemistry, sex, chief complaint, tumor size, tumor-related mortality, and tumor recurrence and metastasis. RESULTS: A total of 41 reports with 80 PF patients (of whom 70 were adult PF and 10 were pediatric PF patients) confirmed by histological and immunohistochemical findings were included. Of a total of 80 tumors, 62 (78%) were located in the gastric antrum, 42 (65%) presented with ulceration, and 48 (74%) were resected by partial gastrectomy. Median tumor size of the resected specimen was larger in pediatric PF than in adult PF cases (5.3âcm vs 4.0âcm, Pâ=â.036). However, there was no difference between pediatric and adult PFs in immunohistochemical expression, sex predominance, chief complaint, tumor-related mortality, and tumor recurrence and metastasis during the follow-up periods. CONCLUSION: Other than increased tumor growth in pediatric PFs, PF is a single disease entity with similar pathological features and benign clinical behavior regardless of onset age.

BACKGROUND: Obturator hernia (OH) is a rare but serious disease associated with high morbidity and mortality due to advanced patient age and comorbidities. This study evaluated the feasibility of a laparoscopic approach to OH. STUDY DESIGN: We retrospectively reviewed the records of 32 patients (median age 84 years; 31 women) with OH treated between 2003 and 2016. RESULTS: Five patients with incidental OH underwent total extraperitoneal (TEP) repair. Of 27 patients with incarcerated OH, 18 patients underwent laparotomy, 13 of which required bowel resection, and the remaining 9 patients underwent preoperative ultrasound-guided manual OH reduction. Of 6 patients with successful OH release, 3 and 2 patients underwent TEP and transabdominal preperitoneal repair, respectively, and 1 patient declined the operation. Three patients with failure underwent laparoscopic exploration and conversion to open operation for bowel resection. Comparing the open and laparoscopic groups, the median operation times were 67.5 minutes vs 124 minutes, respectively (p = 0.004); median postoperative stay was 19 vs 11 days, respectively (p = 0.028); and Clavien-Dindo grade II or higher complications tended to be lower (28% vs 8%, respectively; p = 0.359). Even in patients without bowel resection, the median postoperative stay was significantly shorter in the laparoscopic group compared with the open group (7.5 vs 15 days, respectively; p = 0.032). During a mean follow-up of 24.5 months, the 3-year recurrence rate for OH was 25% for non-mesh repair and 0% for mesh repair (p = 0.335). Three- and 5-year cumulative survival rates were 83% and 71%, respectively. CONCLUSIONS: Laparoscopic operations after ultrasound-guided manual reduction can be an alternative to emergent laparotomy in select OH patients.

OBJECTIVES: This study aimed to evaluate the long-term outcomes of neoadjuvant chemoradiotherapy with S-1 in patients with locally advanced rectal cancer. METHODS: A multi-institutional, prospective, phase II trial was conducted between April 2009 and August 2011. The study enrolled 37 patients with histologically proven rectal carcinoma (T3-4 N0-3 M0) who underwent neoadjuvant chemoradiotherapy with S-1. Total mesorectal excision with D3 lymphadenectomy was performed 4-8 weeks after completion of neoadjuvant chemoradiotherapy with S-1 in 36 patients. We then analyzed late adverse events, overall survival, and disease-free survival. RESULTS: The median patient age was 59 years (range: 32-79 years); there were 24 men and 13 women. Ten patients had Stage II disease, and 27 had Stage III disease. Severe late adverse events occurred in 7 patients (18.9%). The 5-year disease-free survival was 66.7%, and the 5-year overall survival was 74.7%. The median follow-up period was 57 months. Local recurrences developed in 5 patients (13.5%), and distant metastases developed in 8 (21.6%). CONCLUSION: Neoadjuvant-synchronous chemoradiotherapy with S-1 for locally advanced rectal cancer is feasible in terms of adverse events and long-term outcomes.

RESUMO
PURPOSE: More effective methods are needed for breast reconstruction after breast-conserving surgery for breast cancer. The aim of this clinical study was to assess the perioperative and long-term outcomes of adipose-derived regenerative cell (ADRC)-enriched autologous fat grafting. METHODS: Ten female patients who had undergone breast-conserving surgery and adjuvant radiotherapy for breast cancer were enrolled. An ADRC-enriched fat graft prepared from the patient's adipose tissue was implanted at the time of adipose tissue harvest. The perioperative and long-term outcomes of the grafts, which included safety, efficacy, and questionnaire-based patient satisfaction, were investigated. RESULTS: The mean operation time was 188 ± 30 min, and the mean duration of postoperative hospitalization was 1.2 ± 0.4 days. No serious postoperative complications were associated with the procedure. Neither recurrence nor metastatic disease was observed during the follow-up period (7.8 ± 1.5 years) after transplantation. Of 9 available patients, "more than or equal to average" satisfaction with breast appearance and overall satisfaction were reported by 6 (66.7%) and 5 (55.6%) patients, respectively. CONCLUSIONS: ADRC-enriched autologous fat transplantation is thus considered to be safe perioperatively, with no long-term recurrence, for patients with breast cancer treated by breast-conserving surgery, and it may be an option for breast reconstruction, even after adjuvant radiotherapy.

Treatment results of locally advanced rectal cancer without preoperative chemoradiotherapy (CRT) in Japan do not differ from those of Western countries. Preoperative CRT with new anticancer agents may decrease local recurrence rate and prevent distant metastases, thus improving survival. We conducted a trial to evaluate feasibility of neoadjuvant CRT using S-1 in patients with locally advanced rectal cancer. A multi-institutional (17 specialized centres), interventional, phase II trial was conducted from April 2009 to August 2011. Patients fulfilling the following requirements before neoadjuvant CRT were included: histologically proven rectal carcinoma; tumour in the upper or lower rectum; cancer classified as T3-4 N0-3 M0. Neoadjuvant CRT with S-1 (80 mg/m2/day on days 1-5, 8-12, 22-26, and 29-33) and irradiation (total 45 Gy/25 fr, 1.8 Gy/day, on days 1-5, 8-12, 15-19, 22-26, and 29-33) was performed. Total mesorectal excision with D3 lymphadenectomy was performed during weeks 4 and 8 after completion of neoadjuvant CRT. The primary endpoint was completion rate of neoadjuvant CRT. Secondary endpoints were response rate to neoadjuvant CRT, short-term clinical outcomes, curative resection rate, and pathologic response (grade 2/3). Of the 37 patients included, 86.5% completed neoadjuvant CRT (95% CI, 75.5-97.5%), and 10.8% (4) experienced an adverse event (grade 3/4). Response rate (RECIST 1.0) was 56.8% (95% CI, 40.8-72.7%), and pathologic response rate was 48.6% (95% CI, 32.5-64.8%). This study demonstrated that neoadjuvant-synchronous S-1+radiotherapy for locally advanced rectal cancer was feasible in terms of pathologic response and adverse events.

RESUMO
INTRODUCTION: Hydrocele of the canal of Nuck is a rarely encountered entity. We report a case underwent laparoscopic totally extraperitoneal (TEP) treatment for a hydrocele of the canal of Nuck extending in the extraperitoneal space mainly. PRESENTATION OF CASE: A 37-year-old woman complained of painless and reducible swelling in her left groin, and referred to our hospital for surgical management against left inguinal hernia with the incarcerated ovary. Ultrasonography and MR images revealed a cystic mass in the retroperitoneal space, and we diagnosed as an unusual type of hydrocele of the canal of Nuck. The patient was scheduled for laparoscopic treatment. Laparoscopic findings on pneumoperitoneum showed an extraperitoneal cystic tumor with no contact with the left ovary. The fascia and peritoneum of the port site were closed, and then an extraperitoneal space was created. The cystic tumor with the round ligament of the uterus was dissected and resected by the TEP technique. The extended deep inguinal ring was repaired with polypropylene mesh. Postoperative course was uneventful. DISCUSSION: Hydrocele of the canal of Nuck in the adult female is a rare condition. The accurate diagnosis of an inguinal hydrocele in a female is seldom made. Laparoscopic examination provides surgeons with information of inguinal swelling accompanied with retroperitoneal cyst, and consecutive treatment by laparoscopic technique, especially TEP, is useful in regard to minimal damage of the peritoneum. CONCLUSION: Laparoscopic diagnosis and TEP treatment offers a useful alternative in selected patients with hydrocele of the canal of Nuck.
RESUMO
BACKGROUND: To prevent hepatic failure after major hepatectomy, it is important to assess preoperative factors related to liver failure. METHODS: We examined 80 patients who underwent right-sided hepatectomy. Hyperbilirubinemia, uncontrolled ascites, and prolonged postoperative hospital stay were defined as liver failure after hepatectomy, and these 3 factors were evaluated in relation to clinicopathological and surgical factors. RESULTS: In the 80 patients, hyperbilirubinemia was observed in 10 (12.7%) patients, uncontrolled ascites in 18 (22.5%) patients, and prolonged hospital stay after surgery in 39 (48.8%) patients. Multivariate analyses identified platelet count as a risk factor of hyperbilirubinemia, uncontrolled ascites, and prolonged postoperative hospital stay, and the ratio of remnant liver volume to body surface area (RLV/BSA ratio) as an additional risk factor of hyperbilirubinemia and prolonged postoperative hospital stay. CONCLUSIONS: Platelet count and RLV/BSA ratio are useful risk factors for prediction of liver failure after right-sided hepatectomy.

In Western countries, the standard treatment for locally advanced rectal cancer is preoperative chemoradiotherapy followed by total mesorectal excision. However, in Japan, the treatment results without preoperative chemoradiotherapy are by no means inferior; therefore, extrapolation of the results of preoperative treatment in Western countries to Japan is controversial. We consider that survival may be improved by preoperative chemoradiotherapy with new anticancer agents as they are expected not only to decrease the local recurrence rate but also to prevent distant metastases. We are conducting a multicentre Phase II study to evaluate the safety and efficacy of neoadjuvant chemoradiotherapy using S-1 in patients with locally advanced rectal cancer. The primary endpoint is the rate of complete treatment of neoadjuvant chemoradiotherapy. Secondary endpoints are the response rate of neoadjuvant chemoradiotherapy, short-term clinical outcomes, rate of curative resection and pathological evaluation. The short-term clinical outcomes are adverse events of neoadjuvant chemoradiotherapy and surgery-related complications. Thirty-five patients are required for this study.

We herein report a case of sarcomatoid carcinoma that developed in a remnant stomach. A 76-year-old male with a history of distal gastrectomy for a duodenal ulcer 28 years earlier underwent investigation for a tumor in the remnant stomach. An endoscopic survey showed a round elevated tumor measuring 6 cm in diameter, and a biopsy specimen suggested carcinosarcoma. A total gastrectomy of the remnant stomach was performed, and the excised tumor was identified to be a malignant neoplasm consisting of both carcinomatous and sarcomatous components. A diagnosis of sarcomatoid carcinoma was made since the epithelial markers were positive even in the mesenchymal elements of the tumor. To our knowledge, only 4 cases of sarcomatoid carcinoma of the stomach have been reported in the English literature so far.

We report herein the case of 70-year-old woman in whom colon cancer and a synchronous metastatic liver tumour were successfully resected laparoscopically. The tumours were treated in two stages. Both post-operative courses were uneventful, and there has been no recurrence during the 8 months since the second procedure.
RESUMO
INTRODUCTION: A patient with gastroduodenal obstruction caused by an unresectable gastroduodenal or periampullary cancer cannot ingest food and/or liquid. The patient's quality of life rapidly deteriorates, resulting in a dismal prognosis. Stomach-partitioning gastrojejunostomy has been previously reported, and here, we evaluate the laparoscopic procedure. METHODS: We performed laparoscopic stomach-partitioning gastrojejunostomy in 18 patients with unresectable gastroduodenal or periampullary cancers. Data on operation time, blood loss, complications, and postoperative course were retrospectively collected. RESULTS: The mean operation time was 152 min, and conversion to open surgery was not required in any patients. Postoperative complications occurred in three patients (17%) and included cholangitis, anastomotic ulcer hemorrhage, and enterocolitis. The mean time to oral intake was 4.5 days, and the mean and median duration of oral intake were maintained for 133 and 88 days, respectively. CONCLUSION: Laparoscopic stomach-partitioning gastrojejunostomy is a safe and effective procedure that allows patients with gastroduodenal outlet obstruction to eat again and improve the quality of their remaining life.

BACKGROUND AND OBJECTIVES: In patients with acute cholecystitis who cannot undergo early laparoscopic cholecystectomy (within 72 hours), 6 weeks to 12 weeks after onset is widely considered the optimal timing for delayed laparoscopic cholecystectomy. However, there has been no clear consensus about it. We aimed to determine optimal timing for delayed laparoscopic cholecystectomy for acute cholecystitis. METHODS: Medical records of 100 patients who underwent standard laparoscopic cholecystectomy were reviewed retrospectively. Patients were divided into group 1, patients undergoing laparoscopic cholecystectomy within 72 hours of onset; group 2, between 4 days to 14 days; group 3, between 3 weeks to 6 weeks; group 4, >6 weeks. RESULTS: No significant differences existed between groups in conversion rate to open surgery, operation time, blood loss, or postoperative morbidity, and hospital stay. However, total hospital stay in groups 1 and 2 was significantly shorter than that in groups 3 and 4 (P<.01). In addition, the total hospital stay in group 3 was also significantly shorter than that in group 4 (P<.01). CONCLUSIONS: Best timing of laparoscopic cholecystectomy for acute cholecystitis may be within 72 hours, and the delayed timing of laparoscopic cholecystectomy in patients who cannot undergo early laparoscopic cholecystectomy is probably as soon as possible after they can tolerate laparoscopic cholecystectomy.

A 50-year-old woman who was given a diagnosis of acute appendicitis was referred to our hospital. Because an abdominal enhanced CT revealed a dilated and cystic lesion in the appendix, operation was performed under the diagnosis of the suspicion of acute appendicitis or appendiceal mucocele. We performed laparoscopic cecal resection because of the intraoperative diagnosis of intussusception of the appendix. On the resected specimen, an elevated lesion was identified near the base of appendix. Histopathologically it was shown to be a true diverticulum in which the proper muscle layer are intact. To the best of our knowledge, this is the first report of true diverticulosis of the appendix with intussusception in the Japanese literature.

INTRODUCTION: Although laparoscopic totally extraperitoneal hernia repair (TEP) is reported to have a low recurrence rate, few reports address treatment for contralateral occurrence after primary TEP. Most studies on surgical treatment for recurrent inguinal hernia reported on laparoscopic transabdominal preperitoneal repair. The aim of this study was to evaluate the efficacy of repeat TEP for contralateral occurrence after primary TEP for unilateral inguinal hernia. METHODS: We retrospectively reviewed the medical charts of 215 patients undergoing TEP performed between April 2003 and May 2009. We employed a similar approach to that of standard TEP for primary hernia. RESULTS: Twenty eight of 215 patients who underwent unilateral TEP also underwent repeat TEP for contralateral-side hernia occurring after primary TEP. The initial hernia was on the right side in 15 patients and on the left side in 13. The initial hernia was indirect in 26 patients and direct in 2. Mean duration of primary TEP to contralateral occurrence was 54.4 months. Mean operation time for the contralateral occurrence was 73.3 minutes, and there was little intraoperative blood loss. Three patients were converted to an anterior approach because of insufficient surgical field due to injury of the peritoneum. Although the inferior epigastric artery and vein were divided in 4 patients, there were no difficulties during surgery. The postoperative course in all patients was uneventful. CONCLUSIONS: TEP after primary TEP for contralateral occurrence is feasible. Repeat TEP might be an alternative technique for new occurrence of contralateral inguinal hernia after primary TEP.

AIM: To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan. METHODS: We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient's characteristics at PEG using log-rank tests and Cox proportional hazard models. RESULTS: Nine hundred and thirty one patients were followed up for a median of 468 d. A total of 502 deaths were observed (mortality 53%). However, 99%, 95%, 88%, 75% and 66% of 931 patients survived more than 7, 30, 60 d, a half year and one year, respectively. In addition, 50% and 25% of the patients survived 753 and 1647 d, respectively. Eight deaths were considered as PEG-related, and were associated with lower serum albumin levels (P = 0.002). On the other hand, among 28 surviving patients (6.5%), PEG was removed. In a multivariate hazard model, older age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.00-1.03; P = 0.009], higher C-reactive protein (HR, 1.04; 95% CI: 1.01-1.07; P = 0.005), and higher blood urea nitrogen (HR, 1.01; 95% CI: 1.00-1.02; P = 0.003) were significant poor prognostic factors, whereas higher albumin (HR, 0.67; 95% CI: 0.52-0.85; P = 0.001), female gender (HR, 0.60; 95% CI: 0.48-0.75; P < 0.001) and no previous history of ischemic heart disease (HR, 0.69; 95% CI: 0.54-0.88, P = 0.003) were markedly better prognostic factors. CONCLUSION: These results suggest that more than half of geriatric patients with PEG may survive longer than 2 years. The analysis elucidated prognostic factors.

When a patient with a ventriculoperitoneal shunt (VPS) undergoes laparoscopic surgery, there is the concern about possible problems with the shunt due to increased intra-abdominal pressure. We conducted a simplified reflux experiment on VPS valves to demonstrate safety. Each of five different VPS valves was connected via tubes to a glass vessel of our own making. Carbon-dioxide gas was consecutively insufflated into the vessel at 3-25 mm Hg pressure to determine whether reflux occurred when the valves and tubes were empty (opened test) and when filled with physiologic saline (closed test). Reflux occurred for two of five valves at an insufflation pressure of 5 mm Hg or more in the opened test, while not for any valves until 25 mm Hg in the closed test. In clinical settings, there would be no possibility of reflux under the pneumoperitoneum in VPS systems draining cerebrospinal fluid. Laparoscopic surgery in patients with VPS would be performed safely if characteristics of VPS valves are taken advantage of.
