<b><i>Introduction:</i></b> Postoperative pancreatic fistula (POPF) represents the principal determinant of morbidity and mortality after pancreaticoduodenectomy. Since 1994 we have been performing pancreaticogastrostomy with duct-to-mucosa anastomosis (Wirsung-pancreaticogastric anastomosis [WPGA]), but postoperative morbidity, although limited, was still a concern. An original pancreas-transfixing suture technique, named “Blumgart’s anastomosis” (BA), has shown efficacy at reducing fistula rates from pancreaticojejunostomy. Few cohort studies have shown that WPGA with pancreas-transfixing stitches may help reduce the rate of POPF. We designed a novel “Blumgart-type” modification of WPGA (B-WPGA) aiming at harnessing the full potential of the Blumgart design. <b><i>Methods:</i></b> A prospective development study was designed around the application of B-WPGA after pancreaticoduodenectomy for primary periampullary tumors. It focused on describing the early iterations of this technique and on assessing the rate of POPF and delayed post-pancreatectomy hemorrhage (DPH) (primary outcomes), along with other perioperative outcomes. Technically, after mobilizing the pancreatic remnant for a few centimeters, the Wirsung duct is cannulated. A lozenge of seromuscular layer is excised from the posterior gastric wall, matching the shape and size of the pancreas’s cut surface. Two to four transparenchymal pancreatic-to-gastric submucosa U stitches with 4/0 Gore-Tex are positioned cranially and caudally to the Wirsung duct, respectively, mounted on soft clamps, and tied onto the gastric serosa only after duct-to-mucosa anastomosis. Postoperative follow-up was standardized by protocol and included a pancreatic enzyme check on the drain output. <b><i>Results:</i></b> From February 2018 to June 2019, in 15 continuous cases, B-WPGA was performed after pancreaticoduodenectomy. Indications for pancreaticoduodenectomy were mainly ampulla of Vater and pancreatic head adenocarcinomas. There was no operative mortality and no pancreatic anastomosis-related morbidity. Two events (13%) of transiently elevated amylase in the drain fluid, not matching the definition of POPF, were identified in patients with a soft pancreas on postoperative day 2. No DPHs were recorded after a minimum follow-up of 18.6 months. <b><i>Discussion/Conclusion:</i></b> The principles of BA may be safely applied to the WPGA model. B-WPGA allows (1) gentle compression and closure of the small secondary ducts in the pancreatic remnant; (2) partial invagination of the pancreatic body in the gastric wall, with the pancreatic cut surface protected by the gastric submucosa; and (3) prevention of parenchymal fractures, as the pancreaticogastric stitches are tied onto the gastric serosa. Despite the limited number of cases in this study, the absence of mortality and anastomosis-related complications supports further reproduction of this technical variant. Larger studies are necessary to determine its efficacy.

Abstract A 77-year-old woman with a solitary existence was referred to our hospital for the treatment of pancreatic tumors. Computed tomography revealed an 18-mm mass in the pancreatic head that had invaded the right side of the superior mesenteric vein (SMV) and a 32-mm mass in the pancreatic tail. We performed middle segment-preserving pancreatectomy (MSPP) with SMV resection and reconstruction. The TNM classifications were T2, N1, M0, stage IIB in the pancreatic head, and T2, N0, M0, stage IB in the pancreatic tail, respectively. Postoperatively, the blood glucose was well controlled using only hypoglycemic drug, and insulin preparation was not necessary. No fatty diarrhea was found using a pancreatic enzyme supplement. After 9 months of follow-up, no recurrence was found. MSPP for pancreatic head and tail carcinomas seemed acceptable for both preserving the postoperative quality of life and ensuring curative resection especially in elderly patient with a solitary existence.

A hypertensive man with chronic kidney disease (CKD) secondary to polycystic disease was hospitalized for symptoms related to hypoglycemia. Fasting test elicited symptomatic hypoglycemia after 12 hours, which was associated with inappropriately unsuppressed normal insulin and C-peptide levels. Neither ultrasonography (US) nor magnetic resonance imaging detected any pancreatic tumor. Endoscopic ultrasonography (EUS) showed a small isoechogenic nodule suspect for neuroendocrine tumor in the pancreatic head. 68Gallium-DOTA-Tyr3-octreotide positron emission tomography/computed tomography revealed intense uptake by a small region in the pancreatic head. Surgical exploration together with intraoperative US confirmed the nodule in the pancreatic head and evidenced another hypoechogenic one in the uncinate process. Both nodules were enucleated, but only the latter, which had not been previously detected by EUS, proved compatible with insulinoma on combined histology and immunohistochemistry. After nodule enucleation, hypoglycemia resolved and did not relapse. Insulinoma, as a major cause of unexplained hypoglycemia, requires careful hormonal and instrumental workup. In patients with CKD, the interpretation of biochemical criteria for the diagnosis of insulinoma can be challenging. Localization techniques may display pitfalls. Surgery is curative in most patients but long-term follow-up is required.

Resection Of The Pancreas

The experience of surgical treatment of 154 patients having chronic pancreatitis with preferential injury of the pancreas head which underwent different operative interventions: isolated resection of pancreatic head ( based upon Berger surgery - 24, Frey surgery - 39), pancreatoduodenal resection ( with gastric resection - 22, with preserved pylorus - 43) and drainage surgeries - 26 is presented in the article. The surgery of isolated resection of pancreatic head has less number of nearest unfavorable results compared with pancretoduodenal resection with preserved pylorus. Proximal resection of the pancreas the variants of which are different isolated resection of pancreatic head is superior upon surgeries with full or partly resection of the duodenum due to fast normalization of the motor-evacuation function, less rate of the intestinal reflux and portion character of duodenal evacuation. In the follow-up period after pancreatoduodenal resection, atrophic processes occur in distal areas of the pancreas which are followed by clinical manifestations of exo- and endocrinous insufficiency. The surgery of longitudinal pancreatic jejunostomy does not avoid pathologic changes in the organ head and pain syndrome.

Purpose: To analyze and compare the results of robotic partial nephrectomy (RPN) at a single center with the previous large-scale studies in terms of perioperative and oncological outcomes.Materials and Methods: We retrospectively evaluated 1,013 cases of RPN in our center database from December 2008 to August 2018. Total 11 cases were excluded in final analysis. We evaluated perioperative outcomes as the Trifecta achievement, which is defined as no positive surgical margin (PSM), no perioperative complications greater than Clavien-Dindo classification I and a warm ischemia time of <25 minutes. In addition, we analyzed pathological and oncological outcomes; recurrence, metastasis, all-cause deaths, cancer-specific deaths, and 5-year survival rates.Results: In 1,002 cases, the Trifecta achievement was 61.1% (n=612). The postoperative complication was 18.4% (n=184) but most were grade 2 or less (14.9%, n=145). Ninety-three cases (9.28%) had benign and 907 cases (90.5%) had malignant pathologies. A local recurrence were 14 cases (1.54%) and distant metastasis were 20 cases (2.2%) during follow-up periods. Allcause death rate was 1.2% (n=11) and cancer-specific death rate was 0.2% (n=2). The median follow-up period was 39 months. A 5-year recurrence-free survival rate, cancer-specific survival rate, and overall survival rate were 95.2%, 99.7%, and 98.4%.Conclusions: In summary, our data shows comparable perioperative outcomes to other largescale studies of RPN in terms of the Trifecta achievement with similar baseline characteristics. In terms of oncological outcomes, there was lower rate of PSM and similar recurrence free survival rate.

Background: Endoscopic ultrasonography (EUS) is an important tool for diagnosis and pretreatment staging of primary gastric lymphoma. The aim of the study was to evaluate the diagnostic importance of endosonography (EUS)in gastric lymphoma; to assess the depth of tumoral infiltration in low-grade gastric lymphoma of mucosa-associated lymphoid tissue (MALT) and to assess EUS response to medical treatment (Cyclophosphamid/Mabtera and/or anti-Helicobacter pylori therapy). Methods: 26 patients with MALT gastric lymphoma were investigated by EUS. Six of them were evaluated after the eradication of Helicobacter pylori infection and 20 after and during the cyclophosphamide/Mabtera and anti H.pylori treatment. EUS staging was compared with histopathology. Tumors were staged according to the 2000 TNM and modified Ann Arbor classification. Results: Six patients were treated with anti - Helicobacter pylori eradication therapy. Full regression of lymphoma was observed in 2 of 6 (33.3%) patients, which was endoscopicaly and histologicaly proved. EUS correlated with histology in all (6/6). In 20 patients treated with cyclophosphamide/Mabtera therapy, EUS revealed regression of lymphoma in 14 cases. Positive correlation with histology was found in 11 patients (11/14; 78%). The initial EUS showed an increased wall thickness more than 5mm in 24 of 26 patients (92%). The thickening was predominantly of mucosa and submucosa and in 11 patients extended the muscularis propria. After the therapy, the gastric wall thickening returned to normal in 14 patients, however, 3 of them still had positive histology findings. In 2 cases, during the follow-up, the EUS showed remained thickening of gastric wall, whereas biopsies were negative. Six months later histology revealed progressive low-grade MALT lymphoma in this cases. Conclusion: EUS appears to be a sensitive procedure for initial staging and assessment of treatment response and long-term follow up in patients with gastric lymphoma. The importance of EUS lies in ability to detect relapse early, too.

OBJECTIVEDuring the mini-open posterior corpectomy, percutaneous instrumentation without fusion is performed above and below the corpectomy level. In this study, the authors' goal was to compare the perioperative and long-term implant failure rates of patients who underwent nonfused percutaneous instrumentation with those of patients who underwent traditional open instrumented fusion.METHODSAdult patients who underwent posterior thoracic corpectomies with cage reconstruction between 2009 and 2014 were identified. Patients who underwent mini-open corpectomy had percutaneous instrumentation without fusion, and patients who underwent open corpectomy had instrumented fusion above and below the corpectomy site. The authors compared perioperative outcomes and rates of implant failure requiring reoperation between the open (fused) and mini-open (unfused) groups.RESULTSA total of 75 patients were identified, and 53 patients (32 open and 21 mini-open) were available for followup. The mean patient age was 52.8 years, and 56.6% of patients were male. There were no significant differences in baseline variables between the 2 groups. The overall perioperative complication rate was 15.1%, and there was no significant difference between the open and mini-open groups (18.8% vs 9.5%; p = 0.359). The mean hospital stay was 10.5 days. The open group required a significantly longer stay than the mini-open group (12.8 vs 7.1 days; p < 0.001). Overall implant failure rates requiring reoperation were 1.9% at 6 months, 9.1% at 1 year, and 14.7% at 2 years. There were no significant differences in reoperation rates between the open and mini-open groups at 6 months (3.1% vs 0.0%, p = 0.413), 1 year (10.7% vs 6.2%, p = 0.620), and 2 years (18.2% vs 8.3%, p = 0.438). The overall mean follow-up was 29.2 months.CONCLUSIONSThese findings suggest that percutaneous instrumentation without fusion in mini-open transpedicular corpectomies offers similar implant failure and reoperation rates as open instrumented fusion as far out as 2 years of follow-up.

Retroperitoneal Lymph Node Dissection

Abstract Introduction/background: Although a full bilateral template RPLND is thought to be the standard of care for the management of postchemotherapy retroperitoneal residual masses for nonseminomatous germ cell tumors (NSGCT), in the past decade modified templates have become increasingly popular. In this study, we aimed to present our oncological and perioperative outcomes of consecutive seventeen NSGCT patients who underwent a modified template unilateral PC-RPLND for retroperitoneal residual disease. Materials and Methods: We retrospectively evaluated the medical records of 17 consecutive NSGCT patients who underwent modified template unilateral PC-RPLND in our university hospital between 2017 and 2020. All patients had normal serum tumour markers with residual disease in the retroperitoneum. Surgical characteristics including the size of the retroperitoneal residual mass, residual tumor pathology, removed lymph nodes, positive percentage of removed lymph nodes, accompanying operations, complications, mean operation time and hospital stay, and long-term results including survival and antegrade ejaculation were evaluated. Results: Eleven patients underwent left and six right-sided surgery. Median residual lymph node diameter was 41mm. Median hospitalisation time was 3.5 days. Median follow-up time was 10.5 months. Necrosis/fibrosis was seen in 6 patients, and teratoma in 11 patients. No viable tumour was seen. No patients died in the follow-up period. None of the patients relapsed during follow-up. Ten/seventeen patients had antegrade ejaculation. Conclusions: Modified template unilateral PC-RPLND leads to very good oncological outcomes with decreased perioperative morbidity as well as better antegrade ejaculation rates. Low volume retroperitoneal disease seems to fit this procedure best.

Background For selected patients with early-stage breast cancer (BC), intraoperative radiation therapy (IORT) has emerged as a convenient alternative to standard whole breast irradiation (WBI). We report a single institution experience with IORT in terms of oncologic outcomes, toxicities, and cosmesis. Methods Clinicopathological and perioperative outcomes of patients who underwent IORT for early-stage BC at a public hospital from 2017 to 2020 were retrospectively retrieved. Toxicity was categorized to acute or chronic based on 6 months post-IORT cutoff. Results 85 patients underwent IORT and had complete data, aged 49‐85 years (mean 62). Intraoperative radiation therapy added 23 minutes on average to the total operative time. Final stage was 0, I, and II in 40%, 58.9%, and 1.1% of patients, respectively. Mean tumor size was 0.8 cm (range .1-2.1), with ductal histology comprising 94% of cases. Surgical margins were positive in 2 patients, and adjuvant WBI was required in 5 patients. After a median follow‐up of 17 months (range 3-41), none of the patients had local recurrence and no mortality was recorded. Early wound complications included wound dehiscence (n = 1), seroma/hematoma (n = 15), and re-operation with loss of nipple-areola complex (n = 1). Chronic skin toxicities were reported in 10 (12%) patients and good or excellent cosmetic outcome was reported in 93% of patients. Conclusions Utilizing IORT among low-risk early BC patients may be a safe and more convenient alternative to traditional WBI, with low toxicity rate, acceptable cosmetic results, and good oncologic outcomes at 17 months. Longer follow-up and further prospective controlled studies are needed to confirm these findings.

Objective: We aimed to evaluate perioperative outcomes and complications of a modified technique of ileal conduit diversion. Methods: Forty-seven cases of radical cystectomy with modified ileal conduit diversion were performed at our institution from January 2015 to January 2020. After radical cystectomy, a segment of ileum was used to pack the conduit and was placed below the digestive anastomosis. Then, the mesentery window of the ileo-ileal anastomosis was sutured. The ureters were anastomosed on their native side on single loop ureteral stents. All procedures were performed by a single surgical team. Intra- and postoperative complications were classified and reported according to the Satava and Clavien–Dindo grading systems. Results: The mean age of population was 66.40±10.14 years, and 76.6% were male. Concomitant diabetes was found in 31.9% of patients. About three quarters of patients had T2G3 bladder cancer. Mean blood loss was 449.36±246.50 ml, and hospitalization was 10.32±5 days. With a mean follow-up of 17.36±12.63 months, the recurrence rate was 17%, and 14.9% of patients died of bladder cancer. Out of the 47 patients, three (4.3%) experienced intraoperative complications, while 15 (31.9%) had postoperative complications. Of these, only three patients experienced Clavien–Dindo complications ⩾grade 3. Multivariate logistic regression model showed that diabetes ( p=0.023) and higher blood loss ( p=0.010) were significantly associated with an increased risk of postoperative complications. We reported one case of ureterointestinal anastomosis stenosis on the left side and none on the right side. Despite our results being promising, larger randomized trials with longer follow-up are needed to explore further the feasibility of this technique on a larger scale. Conclusion: We describe a safe and simple surgical technique with a similar postoperative complications rate and a lower incidence of ureteroileal anastomosis stenosis compared to the standard technique. Level of evidence 4.
