One-layer pancreaticojejunostomy using reinforcing sutures in pancreaticoduodenectomy: A single surgeon’s experience with 122 cases

BackgroundDiscussions about pancreaticojejunostomy (PJ), which can reduce the incidence of postoperative pancreatic fistula (POPF) in pancreaticoduodenectomy (PD), are ongoing. Here we introduce the surgical technique of PJ performed at our hospital and analyze its safety and advantages. MethodsWe retrospectively analyzed 122 patients who underwent one-layer PJ using reinforcing sutures in PD. PJ was performed with reinforcing sutures on the pancreatic stump, including the insertion of a soft silastic catheter for internal drainage followed by suturing of the pancreas and jejunum with one layer. ResultsOf the 122 patients who underwent PJ with this technique, 62 (50.8%) developed POPF. However, 37 (30.3%) had grade A that did not affect the hospital course. Critical POPF occurred in 25 patients: grade B in 20 (16.4%) and grade C in 5 (4.1%). There was no significant difference in the critical POPF patient group according to the pancreas related disease related to pancreatic texture. ConclusionAlthough this technique cannot prevent POPF, we noted no significant difference in POPF versus other surgical techniques. In addition, this technique, which was designed to increase pancreatic texture, is practical and simple for PJ. Therefore, the inexperienced hepatobiliary and pancreatic surgeon can perform it without major complications.

Effect of different pancreatic stump closure techniques after distal pancreatectomy on frequency and severity of acute postoperative pancreatitis

Objective: to study the effect of different pancreatic stump closure techniques and diameter of the main pancreatic duct on frequency and severity of acute postoperative pancreatitis after distal pancreatectomy. Material and Methods. Distal pancreatectomy was performed on 126 patients with neoplasms of body and/or tail of the pancreas. Patients were distributed among four groups based upon the pancreatic stump closure technique applied after distal pancreatectomy: group 1 (control) included the patients with isolated suturing of the main pancreatic duct in the pancreatic stump with its subsequent sealing by the gastrocolic omentum or hemostatic sponge; group 2 patients underwent isolated suturing of the main pancreatic duct in the pancreatic stump with its subsequent sealing with 2-octyl cyanoacrylate biological glue; group 3 patients had their pancreatic stump closure performed with endoscopic linear cutter stapler; group 4 was composed of the patients with external transduodenal transnasal drainage of enlarged (D>3 mm) main pancreatic duct in the pancreatic stump. Results. The occurrence of acute postoperative pancreatitis in the control group amounted to 45.8%, while, in groups 2, 3 and 4, the frequencies were 44.4, 9.7 and 15.0(%), correspondingly. Besides, the control group was characterized by declined occurrence of the moderately severe form of acute postoperative pancreatitis. Use of endoscopic linear cutter stapler and external transduodenal transnasal drainage of the enlarged main pancreatic duct caused lower acute postoperative pancreatitis frequency in the patients with main pancreatic duct in their pancreatic stumps below 5 mm in diameter. Conclusion. Use of proposed pancreatic stump closure techniques after distal pancreatectomy resulted in lower frequencies of occurrence and severity of acute postoperative pancreatitis.

Enhanced Recovery After Pancreatic Surgery Does One Size Really Fit All? A Clinical Score to Predict the Failure of an Enhanced Recovery Protocol After Pancreaticoduodenectomy

BackgroundThe inability to comply with enhanced recovery protocols (ERp) after pancreaticoduodenectomy (PD) is a real but understated issue. Our goal is to report our experience and a potential tool to predict ERp failure in order to better characterize this problem.MethodsFrom January 1, 2014, to January 31, 2016, 205 consecutive patients underwent PD in our center and were managed according to an ERp. Failure to comply with postoperative protocol items was defined as any of: no active ambulation on postoperative day 1 (POD1); less than 4 h out of bed on POD2; removal of nasogastric tube and bladder catheter after POD1 and POD3, respectively; reintroduction of oral feeding after POD4; and continuation of intravenous infusions after POD4. Data were collected in a prospective database.ResultsTaking in consideration the number of failed items and the length of stay, we defined failure of the ERp as no compliance to two or more items. A total of 116 patients (56.6%) met this definition of failure. We created a predictive model consisting of age, BMI, operative time, and pancreatic stump consistency. These variables were independent predictors of failure (OR 1.03 [1.001–1.06] p = 0.01; OR 1.11 [1.01–1.22] p = 0.03; OR 1.004 [1.001–1.009] p = 0.02 and OR 2.89 [1.48–5.67] p = 0.002, respectively). Patient final score predicted the failure of the ERp with an area under the ROC curve of 0.747.ConclusionsIt seems to be possible to predict ERp failure after PD. Patients at high risk of failure may benefit more from a specific ERp.

Postoperative hyperamylasemia (POH) and acute pancreatitis after pancreatoduodenectomy (POAP): State of the art and systematic review

BackgroundPostoperative hyperamylasemia is a frequent finding after pancreatoduodenectomy, but its incidence and clinical implications have not yet been analyzed systematically. The aim of this review is to reappraise the concept of postoperative hyperamylasemia with postoperative acute pancreatitis, including its definition, interpretation, and correlation. MethodsOnline databases were used to search all available relevant literature published through June 2019. The following search terms were used: “pancreaticoduodenectomy,” “amylase,” and “pancreatitis.” Surgical series reporting data on postoperative hyperamylasemia or postoperative acute pancreatitis were selected and screened. ResultsAmong 379 screened studies, 39 papers were included and comprised data from a total of 9,220 patients. Postoperative hyperamylasemia was rarely defined in most of these series, and serum amylase values were measured at different cutoff levels and reported on different postoperative days. The actual levels of serum amylase activity and the representative cutoff levels required to reach a diagnosis of postoperative acute pancreatitis were markedly greater on the first postoperative days and tended to decrease over time. Most studies analyzing postoperative hyperamylasemia focused on its correlation with postoperative pancreatic fistula and other postoperative morbidities. The incidence of postoperative acute pancreatitis varied markedly between studies, with its definition completely lacking in 40% of the analyzed papers. A soft pancreatic parenchyma, a small pancreatic duct, and pathology differing from cancer or chronic pancreatitis were all predisposing factors to the development of postoperative hyperamylasemia. ConclusionPostoperative hyperamylasemia has been proposed as the biochemical expression of pancreatic parenchymal injury related to localized ischemia and inflammation of the pancreatic stump. Such phenomena, analogous to those associated with acute pancreatitis, could perhaps be renamed as postoperative acute pancreatitis from a clinical standpoint. Patients with postoperative acute pancreatitis experienced an increased rate of all postoperative complications, particularly postoperative pancreatic fistula. Taken together, the discrepancies among previous studies of postoperative hyperamylasemia and postoperative acute pancreatitis outlined in the present review may provide a basis for stronger evidence necessary for the development of universally accepted definitions for postoperative hyperamylasemia and postoperative acute pancreatitis.

Manual suture or stapler closure: management of pancreatic stump during distal pancreatectomy

Postoperative pancreatic fistula is the most common complication after distal pancreatectomy.With the update of the domestic and international guidelines or consensuses, the definition of pancreatic fistula has become more standardized.And the classification of pancreatic fistula is able to represent the severity of clinical outcomes more accurately.Currently, the determination of risk factors of pancreatic fistula after distal pancreatectomy, the establishment of prediction model, and the surgical closure mode of pancreatic stump still remain the major topics.With the rapid development of laparoscopic and robotic surgery in pancreatectomy, there are more and more selectionsin transection and managing the pancreatic stump after distal pancreatectomy for prevention of pancreatic fistula.However, there has not been a uniform fashion in terms of manual suture or stapler use to close the pancreatic stump.Herein the current status and development of pancreatic fistula after distal pancreatectomy are reviewed.The strategy of managing the pancreatic stump after distal pancreatectomy should be adopted individually according to the texture and thickness of pancreatic parenchyma.

Prevention of complications of pancreatoduodenal resection in pancreatic cancer

Introduction. Over the past few decades, the incidence of pancreatic cancer has dramatically increased worldwide. Despite the high prevalence of this oncological pathology, there is currently no consensus on the expediency of performing radical reconstructive-plastic surgeries in case of malignant pancreatic tumors.
 Aim: to study the influence of reconstructive-plastic techniques of surgical treatment of pancreatic cancer on the life expectancy of patients and its quality.
 Materials and methods. Analysis of the short and long-term outcomes of surgical treatment of pancreatic cancer was conducted. In total, radical operative interventions were carried out in 32 patients, including 14 men (56.25%) and 18 women (43,75%), aged 37 to 72 (61,5±10,0) years. Pyloro-preserving pancreatoduodenal resection was performed in 20 (62.5%) patients, gastropancreatoduodenal resection — in 6 (18.8%) patients, proximal resection — in 5 (15.6%) patients, distal pancreatic resection — in 1 case (3,1%). Areflux pancreatojejunal anastomosis was formed in patients by the clinic technique.
 Results. Hospital mortality was 6.25%. More than three years after surgery, 15.6% of patients are alive; the median survival rate is 19.5±2.4 months. An assessment of the quality of life and the function of the formed pancreatojejunostomy conducted in the immediate and remote periods showed that the presence of areflux valve reliably prevents the development of pancreatic stump, providing a high level of quality of life for patients.
 Conclusions. The use of organ-preserving and organ-modulating techniques in the treatment of operable pancreatic cancer does not affect survival, but provides an acceptable level of quality of life for patients in the short and long-term perspective after surgery.

A Novel Pancreatic Fistula Risk Score Including Preoperative Radiation Therapy in Pancreatic Cancer Patients

BackgroundPostoperative pancreatic fistula (POPF) is the most serious complication following pancreaticoduodenectomy (PD). Identifying patients at high or low risk of developing POPF is important in perioperative management. This study aimed to determine a predictive risk score for POPF following PD, and compare it to preexisting scores. MethodsAll patients who underwent open PD from 2012 to 2017 in two high-volume centers were included. The training dataset was used for the development of the POPF predictive risk score (using the 2016 ISGPS definition), while the testing dataset was used for external validation. The proposed score was compared to the fistula risk score (FRS), the NSQIP-modified FRS (mFRS), and the alternative FRS (aFRS). ResultsOverall, 448 and 213 patients were included in the training and testing datasets, respectively. A probabilistic predictive risk score was developed using four independent POPF risk factors (increasing age, no preoperative radiation therapy, soft pancreatic stump, and decreasing main pancreatic duct diameter). The discriminative capacities of the new score, FRS, mFRS, and aFRS were similar (AUC ranging from 0.73 to 0.79 in the training cohort and from 0.73 to 0.76 in the testing cohort). However, the new score identified more specifically patients at low risk of POPF compared with other scores, in both cohorts, with a 6% false-negative rate. ConclusionsPreoperative radiation therapy is an independent protective factor of POPF following PD. It should be included in the risk score of POPF to identify more precisely patients at low risk for this complication.

Impact of possible risk factors on pancreatic fistula development after pancreaticoduodenectomy: Prospective cohort study

Aim: The most important complication that develops after pancreaticoduodenectomy is anastomosis leak and pancreatic fistula. Pancreatic fistula is thought to be the cause of major complications such as intra-abdominal abscess. The relationship between the development of fistula after pancreaticoduodenectomy and intraoperative risk factors (resection type, pancreatic anastomosis type, pancreatic duct diameter and pancreatic stump structure), along with the effect of pancreatic fistula on morbidity were investigated. Methods: Forty-one patients who had undergone pancreaticoduodenectomy due to periampullary region tumors were included in this study. Patients were divided into two groups as with and without pancreatic fistula, and compared in terms of demographics, preoperative serum bilirubin and serum albumin values, and intraoperative risks (resection type, pancreatic anastomosis type, pancreatic duct diameter and pancreatic stump structure). In addition, the groups were evaluated for the development of post-operative complications. Results: When both groups were compared in terms of intraoperative risk factors (resection type, pancreatic anastomosis type, pancreatic duct diameter and pancreatic stump structure), similar results were obtained for biochemical parameters (P=0.719, 0.599, 0.250, 0.906, respectively). A statistically significant association was found between the occurrence of pancreatic fistula and delay of gastric emptying (P=0.028). No significant relationship was detected between intraabdominal collection-abscess, intraabdominal hemorrhage, wound infection parameters and pancreatic fistula (P=0.204, 0.950, 0.116, respectively). Conclusion: No factors were found to be solely associated with the development of pancreatic fistula following pancreaticoduodenectomy; however, it was concluded that pancreaticoenteric anastomosis technique and the consistency of pancreatic stump may be closely and significantly related.

A Novel Technique for Pancreatic Stump Closure: Clip Ligation of the Duct and Associated Suturing of Pancreas.

Pancreatic fistula (PF) remains the primary source of morbidity after distal pancreatectomy (DP). There is currently no optimal stump closure technique to reduce PF rates. We present a novel technique for pancreatic stump closure using Clip Ligation of the duct and Associated Suturing of Pancreas (CLASP). Five patients (three females) with a median age of 65 years underwent DP and splenectomy for pancreatic body or tail tumour using the CLASP technique. Four of those operations were done laparoscopically. Only one patient developed grade A PF. No other postoperative complications were noticed. The mean length of stay was 5.4 days. The CLASP technique was applicable in both laparoscopic and open distal pancreatectomy. The key points include mobilisation of the pancreatic body from the retroperitoneum and division of the parenchyma with energy device. The technique of pancreatic stump closure involves the isolation of the pancreatic duct (PD), application of a double ligaclip on the proximal duct, division of the PD and finally suturing of the pancreatic stump. The CLASP technique is an effective and safe alternative technique to the current traditional methods of pancreatic stump closure.

Blumgart method using LAPRA-TY clips facilitates pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.

The modified Blumgart method for pancreaticojejunostomy has been shown to reduce the rate of postoperative pancreatic fistula (POPF) in open surgery. We describe a modified Blumgart method using LAPRA-TY suture clips to facilitate laparoscopic pancreaticojejunostomy.We prepared a double-armed 4-0 nonabsorbable monofilament, which was ligated using the LAPRA-TY clip at the tail end, 12-cm in length. Next, the U-suture was placed through the pancreatic stump and the seromuscular layer of the jejunum. We performed duct-to-mucosa suturing with a 5-0 absorbable monofilament. After completing the duct-to-mucosa suturing, as a final step we placed the sutures through the seromuscular layer of the jejunum on the ventral side and tightly secured the thread with the LAPRA-TY clips. We performed laparoscopic Blumgart pancreaticojejunostomy during pancreaticoduodenectomy in 39 patients. We compared the surgical outcomes of 19 patients who underwent Blumgart pancreaticojejunostomy using the LAPRA-TY clips (LAPRA-TY group) with 20 patients undergoing surgery not using the LAPRA-TY clips (conventional group).The rate of clinically relevant postoperative pancreatic fistula in the LAPRA-TY group was 21.1%, which did not differ significantly from the rate of the conventional group. However, the mean time of pancreaticojejunostomy in the LAPRA-TY group was 56.2 min (range, 39–79 min), which was significantly shorter than that of the conventional group (69.7 min; range, 53–105 min, P < .001).Although the modified Blumgart pancreaticojejunostomy using LAPRA-TY suture clips did not improve the pancreatic fistula rate, it allowed for shorter operative times. Thus, this procedure lends itself to positive surgical and patient outcomes.

Robot-Assisted Radical Antegrade Modular Pancreatosplenectomy Including Resection and Reconstruction of the Spleno-Mesenteric Junction

This article shows the technique of robot-assisted radical antegrade modular pancreatosplenectomy, including resection and reconstruction of the spleno-mesenteric junction, for cancer of the body-tail of the pancreas. The patient is placed supine with the legs parted and a pneumoperitoneum is established and maintained at 10 mmHg. To use the surgical system, four 8 mm ports and one 12 mm port are required. The optic port is placed at the umbilicus. The other ports are placed, on either side, along the pararectal line and the anterior axillary line at the level of the umbilical line. The assistant port (12 mm) is placed along the right pararectal line. Dissection begins by detaching the gastrocolic ligament, thus opening the lesser sac, and by a wide mobilization of the splenic flexure of the colon. The superior mesenteric vein is identified along the inferior border of the pancreas. Lymph node number 8a is removed to permit clear visualization of the common hepatic artery. A tunnel is then created behind the neck of the pancreas. To permit safe resection and reconstruction of the spleno-mesenteric junction, further preemptive dissection is required before dividing the pancreatic neck to bring in clear view all relevant vascular pedicles. Next, the splenic artery is ligated and divided, and the pancreatic neck is divided, with selective ligature of the pancreatic duct. After vein resection and reconstruction, dissection proceeds to complete the clearance of peripancreatic arteries that are peeled off from all lympho-neural tissues. Both celiac ganglia are removed en-bloc with the specimen. The Gerota fascia covering the upper pole of the left kidney is also removed en-bloc with the specimen. Division of short gastric vessels and splenectomy complete the procedure. A drain is left near the pancreatic stump. The round ligament of the liver is mobilized to protect the vessels.

Postoperative pancreatic fistula after pancreatic resection.

The failure of pancreatic anastomosis after the proximal pancreaticoduodenectomy (PD) and the failure of pancreatic stump after the distal pancreatectomy with a resulting postoperative pancreatic fistula remain the most feared complications after pancreatic resection. Surgeons have been trying to find a reliable reconstructive technique of pancreatic anastomosis for decades. A literature search was performed to January 2020. Studies giving a detailed description of the pancreatic anastomosis after open PD and pancreatic stump closure techniques after the distal pancreatectomy were included. The aim of this study was review reported data derived from meta-analyses concerning the incidence of POPF according to the International Study Group of Pancreatic Surgery. A comparison of various surgical techniques and their impact on POPF incidence was made. In the group of clinically relevant POPF (CR- POPF), a well established difference between the patients undergoing POPF-associated interventional drainage or reoperation was observed. Meta-analyses showed that the patients with CR- POPF were statistically more likely to have a small duct size, soft gland texture, particular pancreatic neoplasms and an excessive intraoperative blood loss. Grade C POPF following PD, although uncommon, occurs with a defined incidence and is associated with a substantial morbidity, prolonged hospitalization, delayed recovery and a significant mortality. According to the results of various meta-analyses, pancreatogastrostomy and pancreatojejunostomy seemed to be comparable anastomotic techniques following PD (Ref. 54).

Reinforced stapler vs. ultrasonic dissector for pancreatic transection and stump closure for distal pancreatectomy: a propensity-matched analysis

Reinforced stapler vs. ultrasonic dissector for pancreatic transection and stump closure for distal pancreatectomy: a propensity-matched analysis

КЛИНИКО-ЭПИДЕМИОЛОГИЧЕСКИЕ ОСОБЕННОСТИ ПРИ ОЧАГОВОЙ ПАТОЛОГИИ ГОЛОВКИ ПОДЖЕЛУДОЧНОЙ ЖЕЛЕЗЫ НА ФОНЕ ХРОНИЧЕСКОГО ОПИСТОРХОЗА

In this retrospective study basic morphologic, clinical and epidemiological features of pancreatic head lesions in patients with and without concomitant chronic opisthorchiasis are compared. The analysis of 63 consecutive pancreaticoduodenectomies performed at out low-volume center from 2007 to 2019 revealed increased rate of opisthorchiasis being present simultaneously with neoplastic and benign pancreatic head lesions in rural population which is due to dietary habits of suburbanite. Active cholangitis in comorbid patients was seen 13,6 times more often when compared with “pure” lesion. Daily amount of bile (in patients with biliary drainage tubes) was on average 105 ml more in the group of patients with chronic opisthorchiasis. Surprisingly, we didn’t observe some morphologic features we expected in Opisthorchis felineus group. The rates of hard pancreatic stumps and wide pancreatic ducts were equal in both group of patients. However, further studies should reveal, if O. felineus is independent risk factor for biliary and/or pancreatic fi stula.

Contrast-enhanced computed tomography in evaluation of pancreatic stump volume in pancreaticoduodenectomy

To analyze the role of contrast-enhanced computed tomography in evaluation of pancreatic stump volume for prediction of significant pancreatic fistula. A retrospective analysis enrolled 99 patients. Patients were divided into 2 groups depending on the course of postoperative period and development of clinically significant pancreatic fistula. The first group included 24 patients (25%) with clinically significant postoperative pancreatic fistula. The second group included 75 patients (75%) without postoperative complications. Pancreatic structure, pancreatic parenchyma thickness (mm), pancreatic duct diameter (mm) and volume of pancreatic stump (cm3) were preoperatively analyzed considering contrast-enhanced computed tomography data. The risk of postoperative pancreatic fistula is 10 times higher in case of soft structure of the pancreas, 1,7 times higher in decrease of pancreatic duct diameter, 9,3 times higher in increased volume of residual pancreatic parenchyma, 8.6 times higher in increase of pancreatic parenchyma thickness. Contrast-enhanced computed tomography is valuable for preoperative evaluation of the volume of residual pancreatic parenchyma and identification of patients with high risk of postoperative pancreatic fistula.

EUS-guided drainage of post-distal pancreatectomy collections using lumen apposing metal stent: a single center experience

Introduction: Postoperative fluid collections (PoFC) are common complications after distal pancreatectomy. Symptoms related to PoFC include signs of infection, pain, dyspepsia and left-upper quadrant pressure sensation, although are more frequently asymptomatic radiological findings during post-operative routine controls. No recommendations exist regarding the management of PoFC. Endoscopic ultrasound (EUS) guided drainage of symptomatic PoFC allows to avoid reoperation, long-term percutaneous drainage and development of external pancreatic fistulas. Material and Methods: From January 2017 and December 2018, 92 consecutive distal pancreatectomies (24 of them spleen-preserving) were performed at our institution. All the patients who developed PoFC were included in the study. All the symptomatic PoFCs were drained using lumen apposing metal stents (LAMS; Hot-AXIOS, Boston Scientific, USA) Results: Fifteen patients (16%) developed PoFC at the resection margin of the pancreatic stump. All these patients had a PoPF (5 grade A and 10 grade B). Six of them were symptomatic and the complication was observed at CT scan within one month after discharge. Nine of them were asymptomatic and were observed at post-operative ultrasound scan follow-up. All the 6 patients with PoFC related symptoms underwent EUS-guided trans-gastric drainage using LAMS as first choice. Five out of six had an uneventful course. In one female patient, dislocation of the LAMS into the stomach occurred during endoscopic debridement 8 days after the procedure. An urgent laparotomy was necessary with open drainage and gastric suture with complete resolution of the condition. The other stents were removed after one month and no recurrence of collection were observed. Conclusions: Most of PoFCs are asymptomatic but whenever symptoms are present, the EUS guided drainage is feasible and safe and has a high success rate. When the collections are not completely accessible from the stomach or the duodenum, percutaneous or minimally invasive surgical approach should be preferred.

Position of the Pancreas Division Line and Postoperative Outcomes After Distal Pancreatectomy.

In distal pancreatectomy (DP), the position of the pancreas division line (PDL) changes depending on the location or nature of the tumor. Here, we investigated the relationship between PDL and postoperative complications after DP. We retrospectively analyzed data of 140 patients who underwent DP at Tokyo Medical and Dental University Hospital between January 2011 and September 2018. PDL was defined as the distance from the left margin of the portal vein to the edge of the pancreatic stump on the coronal plane of computed tomography. The mean PDL was 15.1 (range 0-74.3) mm. PDL was significantly longer in patients with portal venous system thrombosis (PVST) than in those without PVST (47.6 vs. 0mm, p < 0.001). The PDLlong (≥ 20mm) group underwent surgery with a significantly shorter duration (253 vs. 294min, p < 0.001) and experienced a lower volume of blood loss (20 vs. 256.5mL, p < 0.001) than the PDLshort (< 20mm) group. Six months after surgery, the increase in HbA1c level was significantly higher in the PDLshort group than in the PDLlong group (0.5 vs. 0.35%, p = 0.041). Except for PVST, there was no significant difference in postoperative complications between the two groups. In DP, pancreas resection with a longer PDL resulted in a significantly shorter duration of surgery, lower estimated blood loss, and superior glucose tolerance than that with a shorter PDL.

Possibility of prognostication for unfavorable results of the pancreaticoduodenal resection on background of the obturation jaundice syndrome

Objective. To determine the possibility of prognostication of unfavorable course of postoperative period in the aspect of the planned pancreaticoduodenal resection for focal affection of pancreaticoduodenal zone on background of obturation jaundice.&#x0D; Materials and methods. The pancreatic head cancer was verified in 174 (64.0%) patients, cancer of the duodenal papilla magna - in 20 (7.4%), cancer of distal hepaticocholedochus - in 24 (8.8%), chronic pseudotumoral pancreatitis - in 54 (20.0%) patients. In the main group (112 patients) preparation to operative intervention was conducted in accordance to elaborated algorithm, and in a control group (160 patients) - in accordance to conventional standards.&#x0D; Results. Pancreaticoduodenal resection with formation of termino-lateral anastomosis in accordance to Whipple procedure was performed in 38 (14.0%) patients, termino-terminal anastomosis in accordance to procedure of Shalimov-Kopchak - in 40 (14.7%), ductomucous pancreaticojejunoanastomosis - in 127 (46.7%), pancreaticogastroanastomosis with invagination of the pancreatic stump into the gastric stump - in 35 (12.9%), pancreaticogastrostomy with deepening of the pancreatic stump into the sleeve, made of the big gastric curvature - in 32 (11.8%). Insufficiency of pancreaticodigestive anastomosis have occurred in 32 (11.8%) patients. Mortality have constituted 5.1%.

Network meta-analysis comparing techniques and outcomes of stump closure after distal pancreatectomy.

The incidence of postoperative pancreatic fistula (POPF) after distal pancreatectomy remains high, and different pancreatic stump closure techniques have been used to reduce the incidence. A network meta-analysis was undertaken to compare the most frequently performed pancreatic stump closure techniques after distal pancreatectomy and determine the technique associated with the lowest POPF rate. A systematic search of the Scopus, PubMed, MEDLINE and Embase databases was conducted to identify eligible RCTs. The primary outcome was the occurrence of clinically relevant POPF. Secondary outcomes were duration of operation, blood loss, intrabdominal collections, postoperative complications and 30-day mortality. Sixteen RCTs including 1984 patients and eight different pancreatic stump closure techniques were included in the network meta-analysis. Patch coverage of the pancreatic stump (round ligament or seromuscular patch) after stapler or suture closure ranked best, with the lowest rates of clinically relevant POPF, lowest volume of intraoperative blood loss, fewer intra-abdominal abscesses, and lower rates of overall complications and 30-day mortality. Round ligament patch closure outperformed seromuscular patch closure in preventing clinically relevant POPF with a significantly larger cohort for comparative analysis. Pancreaticoenteric anastomotic closure consistently ranked poorly for most reported postoperative outcomes. Patch coverage after stapler or suture closure has the lowest POPF rate and best outcomes among stump closure techniques after distal pancreatectomy.
