Background
A novel antireflux procedure combining laparoscopic Nissen fundoplication and Hill repair components was tested in 50 patients with paraesophageal hernia (PEH) and/or Barrett’s esophagus (BE) because these two groups have been found to have a high rate of recurrence with conventional repairs.Methods
Patients with symptomatic PEH and/or non-dysplastic BE underwent repair. Quality of life (QOL) metrics, manometry, EGD, and pH testing were administered pre- and postoperatively.Results
Fifty patients underwent repair. There was no mortality and four major complications. At 13-month follow-up, there was one (2 %) clinical recurrence, and two (4 %) asymptomatic fundus herniations. Mean DeMeester scores improved from 57.2 to 7.7 (p < 0.0001). Control of preoperative symptoms was achieved in 90 % with 6 % resumption of antisecretory medication. All QOL metrics improved significantly.Conclusions
The hybrid Nissen–Hill repair for patients with PEH and BE appears safe and clinically effective at short-term follow-up. It is hoped that the combined structural components may reduce the rate of recurrence compared to existing repairs.2.

Background
The pancreas and peripancreatic region may be a site of metastasis from distant sites. Recent data suggest that pancreatic metastasectomy may achieve long-term survival. We seek to examine our experience with this metastasectomy by reporting the perioperative and survival outcomes.Methods
Patients undergoing resection of isolated pancreatic metastasis were identified from a prospective pancreatic surgical database at the Department of Gastrointestinal Surgery, North Shore campus of the University of Sydney between January 2004 and June 2015 and selected for retrospective review. Data on operative morbidity and mortality were reported. Survival analysis was performed using the Kaplan–Meier method.Results
Fifteen patients underwent pancreatic metastasectomy after a median disease-free interval of 63 months (range 0 to 199). Pancreatoduodenectomy was performed in six patients (40 %), distal pancreatectomy with or without splenectomy in three patients (20 %), and pancreatectomy with other visceral organ resection in six patients (40 %). Major complications occurred in six patients (40 %) without mortality. The median survival was 40 months (95 % CI 24.3 to 53.7), and 1-, 3-, and 5-year survival were 76, 48, and 31 % respectively. Cox proportional hazard model identified margin negative resection (hazard ratio (HR) 10.5; P?=?0.044) as a predictor of improved survival.Conclusion
Long-term survival may be achieved in selected patients with pancreatic metastasis through pancreatic metastasectomy with acceptable morbidity. Selection of patients should be individualized and based on their primary disease origin, biological behavior of the tumor, resectability of the tumor, and the relative effectiveness of systemic or targeted therapies.3.

Background
The aim of this study is to evaluate the long-term results of Muzi’s tension free primary closure technique for pilonidal sinus disease (PSD), in terms of patients’ discomfort and recurrence rate.Methods
This study is a retrospective analysis of prospectively collected data. Five hundred fourteen patients were treated. Postoperative pain (assessed by a visual analog scale, VAS), complications, time needed to return to full-day activities, and recurrence rate were recorded. At 12, 22, and 54 months postoperative, patients’ satisfaction was evaluated by a questionnaire scoring from 0 (not satisfied) to 12 (greatly satisfied).Results
The median operative time was 30 min. The overall postoperative complication rate was 2.52%. Median VAS score was 1. The mean of resumption to normal activity was 8.1 days. At median follow-up of 49 months, recurrence rate was 0.4% (two patients). At 12 months’ follow-up, the mean satisfaction score was 10.3 ± 1.7. At 22 and 54 months’ follow-up, the score was confirmed.Conclusions
Muzi’s tension free primary closure technique has proved to be an effective treatment, showing in the long-term follow-up low recurrence rate and high degree of patient satisfaction. Therefore, we strongly recommend this technique for the treatment of PSD.4.
Purpose
To evaluate the efficacy and safety of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair in patients who have undergone robot-assisted laparoscopic radical prostatectomy (RALP).Methods
From July 2014 to December 2016, TAPP inguinal hernia repair was conducted in 40 consecutive patients who had previously undergone RALP. Their data were retrospectively analyzed as an uncontrolled case series.Results
The mean operation time in patients who had previously undergone RALP was 99.5 ± 38.0 min. The intraoperative blood loss volume was small, and the duration of hospitalization was 2.0 ± 0.5 days. No intraoperative complications or major postoperative complications occurred. During the average 11.2-month follow-up period, no patients who had previously undergone prostatectomy developed recurrence.Conclusions
Laparoscopic TAPP inguinal hernia repair after RALP was safe and effective. TAPP inguinal hernia repair may be a valuable alternative to open hernioplasty.5.

Background
In case of Krukenberg tumor (KT) of gastric origin it is controversial and debated whether radical surgery in case of synchronous KT or metastasectomy in case of metachronous ones is associated with additional benefits. Role of perioperative treatments is unclear.Methods
Among 2515 female patients who were diagnosed with gastric cancer between January 1990 and December 2012 from 9 Italian centers, 63 presented simultaneously or developed KT as recurrence.Results
Thirty patients presented with synchronous KT, while 33 developed metachronous ovarian metastases during follow-up. The differences between the two groups were analyzed and compared. The median age of 63 patients was 48.0 years (range 31–71). Resection was possible in 53 patients (20 synchronous and 33 metachronous). Twelve patients in the synchronous group and 15 patients of the metachronous group underwent hyperthermic intraperitoneal chemotherapy after resection of KT. All of them underwent adjuvant chemotherapy after KT resection. The median survival for all population was 23 months (95 % confidence interval, 7–39 months). The median survival time in the metachronous group was 36 months, which was significantly longer than that in the synchronous group, 17 months, p < 0.0001.Conclusions
KT remains a clinical challenge for gastric cancer therapy. The extent of disease and feasibility of removal of the metastatic lesion must be carefully evaluated prior to surgery to define the patients group who could benefit most from a resection associated with perioperative treatments.6.

Objective
Anatomic reconstruction of the medial patellofemoral ligament using autologous gracilis tendon in an implant-free technique on the patellar side to regain patellofemoral stability.Indications
Recurrent dislocations, primary dislocation with high risk of recurrence, and dislocations with (osteo-)chondral flake fractures. As combined approach together with other procedures (trochleoplasty, tibial tubercle osteotomy). Revisions.Contraindications
As an isolated procedure in patients with high degrees of trochlear dysplasia, chronic dislocation of the patella, and patellofemoral maltracking without instability.Surgical technique
Harvesting of the gracilis tendon. Drilling of a V-shaped tunnel with a special aiming device in anatomic position on the medial side of the patella. Drilling of a femoral tunnel in anatomic position under fluoroscopic control. Passage of the graft, arthroscopic-guided tensioning, and femoral fixation with a biodegradable interference screw.Postoperative management
Partial weight bearing (20 kg) for 1–2 weeks. No limitation in range of motion. No orthosis. Specific sports allowed after approximately 3 months.Results
Perioperative complications associated specifically with the technique were observed in 1.0?% (7 of 729 cases). In a series of 72 consecutive cases from May 2010 to October 2010, the following were recorded after 4.0 ± 0.1 years: recurrent dislocations in 3.2?%, a Tegner activity score of 5.1 ± 1.8, and subjective satisfaction in 92?% (follow-up rate 87.5?%). No fracture of the patella was seen in any of our patients.7.
Purpose
To identify the possible roles of carcinoembryonic antigen (CEA) testing after liver resection for synchronous colorectal liver metastasis (CLM).Methods
The subjects of this retrospective study were patients who underwent complete resection of primary tumors and synchronous CLM between 1997 and 2007 at 20 institutions in Japan. We studied the associations between perioperative CEA levels and the characteristics of recurrence.Results
Recurrence was detected during the median follow-up time of 52 months in 445 (73.7%) of the total 604 patients analyzed. A postoperative CEA level >5 ng/ml was an independent predictor, with the highest hazard ratio (2.25, 95% confidence interval 1.29–3.91, P = 0.004). A postoperative CEA level >5 ng/ml had a specificity of 86.2% and a positive predictive value of 84.2% for recurrence. Patients with a high postoperative CEA level had a significantly higher recurrence rate, with a shorter time until recurrence and a higher frequency of multiple metastatic sites than those with a low postoperative CEA level. Among the patients with recurrence, 173 (52.7%) had an elevated CEA level (>5 ng/ml) when recurrence was detected.Conclusions
A postoperative CEA level >5 ng/ml was an independent predictor of recurrence; however, CEA testing was not a reliable surveillance tool to identity recurrence after liver resection.8.

Background
In patients with IgA nephropathy (IgAN), recurrence after steroid pulse therapy is associated with reduced renal survival. However, the predictors of recurrence have not yet been clarified.Methods
All patients who received 6-month steroid pulse therapy from 2004 to 2010 in our four affiliated hospitals and achieved a reduction of proteinuria to <0.4 g/day 1 year after treatment were retrospectively evaluated. The primary outcome was proteinuria ≥1.0 g/day during follow-up or additional antiproteinuric therapy. Two histological classifications were evaluated, the Oxford Classification with a split system and Japanese histological grades (HGs) with a lumped system.Results
During a median follow-up of 3.4 years, 27 (26.7 %) of the 101 patients showed recurrence. Multivariate analysis showed that HG was the only significant predictor of recurrence, with HG 2+3+4 vs HG 1 having a hazard ratio of 7.38 (95 % confidence interval 1.52–133). Furthermore, in patients with mesangial hypercellularity according to the Oxford Classification, cumulative rate of recurrence-free survival was greater in patients with steroid therapy plus tonsillectomy compared with those who received steroid therapy alone (Log-rank test, P = 0.022). However, this association was not observed in patients without mesangial hypercellularity.Conclusions
HG is a novel predictor of recurrence after steroid pulse therapy in patients with IgAN. Moreover, the combination of steroid pulse therapy plus tonsillectomy may indicate a lower risk of recurrence in patients with mesangial hypercellularity, as defined by the Oxford Classification.10.

Background
Approximately 10–20 % of esophageal cancer patients in whom recurrence is diagnosed experience late recurrence beyond 2 years after esophagectomy. However, the risk of late recurrence is still unclear. The aim of this study was to identify the risk factors of late recurrence for appropriate postoperative surveillance.Methods
A total of 447 patients underwent radical esophagectomy and reconstruction for esophageal cancer from 2005 to 2014. Patients who had recurrence beyond 2 years after esophagectomy were defined as the late recurrence group and the remaining patients with recurrence as the early recurrence group. A comparison of the clinicopathological factors and prognosis was performed between patients with early recurrence, late recurrence, and no recurrence.Results
Recurrences were recognized in 117(26.2 %) of the 447 patients. Recurrence was diagnosed within 2 years after surgery in 103 patients (88.0 %) and after 2 years in 14 patients (12.0 %). Patients with late recurrence showed a favorable prognosis compared with those with early recurrence (P = 0.0131), and late recurrence was an independent factor associated with a favorable prognosis after recurrence (HR 0.199, P = 0.025). In the comparison between patients with late recurrence and those with no recurrence who had a minimal recurrence-free survival of 2 years, pathological lymph node metastasis at esophagectomy was found to be an independent predictor of late recurrence (HR 7.296, P = 0.043).Conclusions
Pathological lymph node metastasis at esophagectomy is a risk factor of late recurrence for esophageal cancer, and a close, lifelong follow-up is recommended for such patients.11.

Purpose
This study aimed to determine the outcome of perineal hernia repair with a biological mesh after abdominoperineal resection (APR).Method
All consecutive patients who underwent perineal hernia repair with a porcine acellular dermal mesh between 2010 and 2014 were included. Follow-up was performed by clinical examination and MRI.Results
Fifteen patients underwent perineal hernia repair after a median of 25 months from APR. Four patients had a concomitant contaminated perineal defect, for which a gluteal fasciocutaneous flap was added in three patients. Wound infection occurred in three patients. After a median follow-up of 17 months (IQR 12–24), a clinically recurrent perineal hernia developed in 7 patients (47 %): 6 of 11 patients after a non-cross-linked mesh and 1 of 4 patients after a cross-linked mesh (p = 0.57). Routine MRI at a median of 17 months revealed a recurrent perineal hernia in 7 of 10 evaluable patients, with clinical confirmation of recurrence in 5 of these 7 patients. No recurrent hernia was observed in the three patients with combined flap reconstruction for contaminated perineal defects.Conclusion
A high recurrence rate was observed after biological mesh repair of a perineal hernia following APR.12.

Introduction
Pulmonary metastases are the most common among extrahepatic recurrences from hepatocellular carcinoma (HCC). It causes high risk of HCC-related death, despite recent progress in therapeutic options. However, a role of pulmonary metastasectomy as well as prognostic factors after metastasectomy has not been well established. We aimed to investigate survival outcomes and prognostic factors after pulmonary resection for metastases from HCC.Methods
A series of 93 patients who underwent pulmonary resections for metastases from HCC between June 1990 and July 2013 from multi-institutional database were retrospectively evaluated. Perioperative clinicopathological data and their association with prognosis were investigated.Results
Of 93 patients, 77 had one pulmonary metastasis, and 16 had two or more. Recurrence after pulmonary resection was noted in 60 patients (64.5 %). The estimated 5-year overall survival rate was 41.4 % with median survival time after pulmonary metastatectomy of 39.0 months. Univariate prognostic analysis showed that disease-free interval of ≥12 months was significantly associated with favorable outcomes in both overall survival (5-year rate, 59.3 vs. 28.7 %, p = 0.026) and disease-specific survival (5-year rate, 62.5 vs. 36.2 %; p = 0.038) after pulmonary metastatectomy. A multivariate analysis revealed that disease-free interval was an independent prognostic factor (HR = 2.020, 95 % CI, 1.069–3.816, p = 0.030).Conclusion
We have shown that a disease-free interval was an independent prognostic factor in patients who underwent pulmonary resection for metastasis from HCC. Also, pulmonary metastasectomy can be one of the therapeutic choices for select patients.13.
Purpose
To investigate the risk factors of recurrence of pneumothorax following thoracoscopic bullectomy in young adults.Methods
Between January, 2005 and September, 2015, 167 patients aged ≤40 years underwent initial thoracoscopic bullectomy for primary spontaneous pneumothorax (PSP) at our hospital. Recurrence-free probability was calculated from the date of surgery to recurrence or last follow-up, using the Kaplan–Meier method.Results
Sixteen (9.6%) of the 167 patients suffered a recurrence (collective total, 16 recurrences). The recurrence-free intervals were 3–107 months (median 25.8 months), and the 5-year recurrence-free probability was 85.9%. Multivariate Cox analysis demonstrated that age ≤23 years (p = 0.029) and a history of ipsilateral pneumothorax before surgery (p = 0.029) were significantly associated with higher risk of recurrence. The 5-year recurrence-free probability was 72.3% for patients aged ≤23 years and a history of ipsilateral pneumothorax before surgery and 94.1% for those with neither of these factors (p = 0.001). Recurrence developed within 3 years after surgery in 14 of the 16 patients.Conclusions
Patients ≤23 years of age with a history of ipsilateral pneumothorax before surgery are at significantly high risk of its recurrence, frequently within 3 years; thus, the risk of postoperative recurrence of a pneumothorax must be kept in mind.14.
Objectives
There are only a few detailed reports concerning the prognosticators following surgical resection of pulmonary metastases (PMs) from renal cell carcinoma (RCC). We investigated the prognosis of patients with RCC PMs undergoing pulmonary metastasectomy and identified prognostic factors in a multi-institutional retrospective study.Methods
We retrospectively evaluated 84 patients who underwent resection of PMs from RCC between 1993 and 2014. We assessed the clinicopathological characteristics, focusing on the histological findings of PMs. We classified the histology into three types: pure clear cell carcinoma (N = 68), clear cell carcinoma combined with other histology type (N = 8), and non-clear cell carcinoma (N = 8). We examined the relationship between these histological types and the prognosis of patients with PMs from RCC.Results
Complete resection was achieved in 78 patients (93%). The 5-year overall survival rate after metastasectomy was 59.7%. In multivariate analysis, three factors were found to be independent favorable prognostic factors of overall survival after lung metastasectomy [tumor size <2 cm, hazard ratio (HR) = 0.31, 95% confidence interval (CI) 0.13–0.78, P = 0.012; clear cell type, HR = 0.37, 95% CI 0.16–0.83, P = 0.025; and complete resection, HR = 0.27, 95% CI 0.10–0.78, P = 0.015].Conclusions
This study indicates that a histological finding of the clear cell type is a significant favorable prognostic factor in addition to complete resection and a tumor size <2 cm. Histological evaluation of PM lesions is important for predicting survival after metastasectomy.15.

Background
The incidence of esophagogastric junction (EGJ) carcinoma is increasing, but its optimal surgical management remains controversial.Methods
We retrospectively reviewed the database of 400 patients with Siewert type II EGJ carcinoma who were treated surgically at 7 institutions between March 1986 and October 2010. We examined the clinicopathological characteristics, prognostic factors, and risk factors associated with each recurrence pattern.Results
The 5-year overall survival rate of all patients with Siewert type II EGJ carcinoma was 58.4 %. Multivariate analysis showed that T and N stages were independent prognostic factors. We also found that the incidence of lower mediastinal lymph node metastasis (17.7 %) and para-aortic lymph node metastasis (16.1 %) was relatively high. In addition, the para-aortic lymph nodes (N = 39, 9.8 %) were the most frequent node recurrence site, followed by the mediastinal lymph nodes (N = 23, 5.8 %). Lung recurrence was more common than was peritoneal recurrence. Considering each type of recurrence, multivariate analysis showed that the differentiated type was associated with a higher risk of lung recurrence than was the undifferentiated type, and N stage (pN2–3) and positive venous invasion were independent risk factors for liver recurrence.Conclusions
This study is one of the largest retrospective studies to evaluate patients with Siewert type II EGJ carcinoma. Para-aortic and mediastinal lymph node metastasis and recurrence rates were relatively high. During the postoperative follow-up of patients with differentiated Siewert type II EGJ carcinoma, patients should be monitored for lung recurrence more closely than that for peritoneal recurrence.16.

Introduction
The Kono-S (antimesenteric functional end-to-end handsewn) anastomosis has been used for Crohn’s disease in Japan and the USA since 2003 and 2010, respectively. This technique was designed to reduce the risk of anastomotic surgical recurrence. This study reviews the outcomes a decade after the introduction of the Kono-S anastomosis to clinical practice.Methods
This study was conducted at five hospitals (four in Japan and one in the USA). A total of 187 patients in Japan (144 patients, group J) and the USA (43 patients, group US) who underwent Kono-S anastomosis for Crohn’s disease between September 2003 and September 2011 were included.Results
With a median follow-up of 65 months, two surgical anastomotic recurrences have occurred in group J. Kaplan–Meier analysis showed that 5 and 10 years surgical recurrence-free survival rate was 98.6 % in group J. No surgical anastomotic recurrences have been detected in group US with a median follow-up of 32 months. The Kono-S anastomosis was technically feasible and performed in all patients.Conclusion
The Kono-S anastomosis appears to be safe and effective in reducing the risk of surgical recurrence in Crohn’s disease.17.

Objectives
There is increasing evidence that Glasgow Prognostic Score (GPS), based on systemic inflammatory response and albumin level, is a useful predictor of overall survival in patients with various types of cancer.Methods
Patients with lung metastasis from colorectal carcinoma who underwent a lung metastasectomy from 2000 to 2015 were retrospectively investigated. Routine laboratory measurements including serum C-reactive protein (CRP), albumin, and the tumor marker carcinoembryonic antigen were performed before the metastasectomy.Results
Ninety-nine patients underwent 132 lung metastasectomy procedures during the study period. Kaplan–Meier analysis revealed that GPS (p = 0.017), number of metastases (p = 0.004), and the presence of liver metastasis (p = 0.010) were associated with overall survival, while univariate analysis selected GPS (p = 0.028), number of metastases (p = 0.005), and liver metastasis (p = 0.014) as predictive factors associated with overall survival. Multivariate analysis also indicated GPS (p = 0.004), number of metastases (p = 0.004), and liver metastasis (p = 0.013) as predictive factors associated with overall survival.Conclusion
In addition to number of metastases and liver metastasis, GPS is an important predictor of overall survival in colorectal cancer patients who undergo a lung metastasectomy.18.

Purpose
To establish the most effective methods of postoperative surveillance to detect early recurrence of lung adenocarcinoma.Methods
The subjects of this retrospective study were 485 patients with p-stage I–III lung adenocarcinoma, who underwent postoperative surveillance. We examined the sites and detection modes of recurrence and calculated the recurrence-free probabilities. Patients with stage I disease were divided into low- and high-risk recurrence groups using a risk score calculated by assigning points proportional to risk factor regression coefficients.Results
Of the 112 patients with recurrence, 86 had intrathoracic recurrence. Routine computed tomography (CT) revealed recurrence in 60 patients. The recurrence-free probability curves showed that 95% of recurrences were identified within the first 4 years after resection in patients with stage II/III disease. In patients with stage I disease, the predictors of recurrence included male sex, positive pleural lavage cytology, moderate-to-poor differentiation, and visceral pleural invasion. Postoperative recurrences were detected throughout the follow-up period in the high-risk group.Conclusions
Routine chest CT plays an important role in the postoperative surveillance of lung adenocarcinoma. We recommend intensive follow-up during the early post-resection period for patients with advanced stage disease and long-term follow-up for high-risk patients with stage I disease.20.
