Meta-Analysis Review
PURPOSE
To evaluate the effectiveness of pancreatic duct stent placement for preventing postoperative pancreatic fistula after pancreaticoduodenectomy.
METHODS
PubMed, the Cochrane Central Register of Controlled Trials, Embase and ClinicalTrials.gov databases were searched up to February 26, 2022. Studies comparing outcomes following pancreaticoduodenectomy with or without pancreatic duct stents were included. The primary outcome measured was postoperative pancreatic fistula rate, and secondary outcomes were in-hospital mortality rate, reoperation rate, delayed gastric emptying rate and wound infection rate.
RESULTS
Seven RCTs involving 847 patients met the inclusion criteria. No statistically significant difference between the stent group and non-stent group was detected in the incidence of postoperative pancreatic fistula (RR = 0.85, 95%CI: 0.57-1.26, P = 0.41), in-hospital mortality, reoperation, delayed gastric emptying rate and wound infection. Subgroup analyses revealed that use of an external stent significantly reduced the incidence of pancreatic fistula (RR = 0.61, 95%CI: 0.43-0.86, P = 0.005).
CONCLUSIONS
Our preliminary results from this systematic review and meta-analysis revealed that pancreatic duct stents did not reduce the risk of POPF and other complications after pancreaticoduodenectomy compared with no stents. External stents were associated with a reduced POPF rate compared with no stents. Large-scale RCTs are required to assess the effectiveness and assist in clarifying the real role of pancreatic duct stents with respect to the POPF rates after pancreaticoduodenectomy.

Review
BACKGROUND AND AIMS
Routine drainage after pancreatoduodenectomy is a controversial issue. In this article, we present and discuss the current evidence on abdominal drains in pancreatic surgery.
MATERIAL AND METHODS
Review of the pertinent English-language literature.
RESULTS
There is a growing body of evidence showing a lack of benefit of prophylactic drainage after pancreatoduodenectomy. Randomized trials have reported similar outcomes with or without routine drains. If drains were used, early removal was found to be superior to late removal in patients with a low risk of postoperative pancreatic fistula. Consequently, criteria for early drain removal have been developed based on the measurement of drain amylase levels. On the contrary, there exists a subgroup of patients where drains may have a role. In patients with high risk of pancreatic fistula formation, such as those having a soft pancreatic texture, small pancreatic duct and high body mass index, the placement of drains may give sentinel information about future clinical deterioration. The drain may thus help reduce failure-to-rescue rates.
CONCLUSION
Despite much research, there are many unanswered questions regarding drains in pancreatic surgery. It is evident that routine drainage should be abandoned for a more selective strategy. Furthermore, what is needed is a postoperative warning score that early on can identify patients at risk of a pancreatic fistula, without the routine placement of drains.

Review
: Postoperative pancreatic fistula is the most troublesome complication after pancreaticoduodenectomy, and is an on-going area of concern for pancreatic surgeons. The specific pancreatic reconstruction technique is an important factor influencing the development of postoperative pancreatic fistula after pancreaticoduodenectomy. : In this paper, we briefly introduced the definition and relevant influencing factors of postoperative pancreatic fistula. We performed a search of all meta-analyses published in the last 5 years and all published randomized controlled trials comparing different pancreatic anastomotic techniques, and we evaluated the advantages and disadvantages of different techniques. : No individual anastomotic method can completely avoid postoperative pancreatic fistula. Selecting specific techniques tailored to the patient's situation intraoperatively may be key to reducing the incidence of postoperative pancreatic fistula.

AIMS
To compare the short-term outcomes of patients undergoing open DP (ODP) and laparoscopic DP (LDP); and to analyze the association between the section site of the pancreas and pancreatic fistula.
MATERIALS AND METHODS
Clinical, perioperative, and histopathologic data of patients who underwent ODP and LDP between 2009 and 2019 were retrospectively analyzed.
RESULTS
70 patients were included. 39 (56%) underwent ODP and 31 (44%) underwent LDP. The tumor size in ODP group was 70mm and in LDP group was 45mm (p = 0,032) Blood loss was lower in LDP group (229mL versus 498mL) (p = 0,001). Operative time, spleen preservation, B/C pancreatic fistula, major morbidity, reoperation, and length of hospital stay, were similar in both groups. There was no postoperative mortality. No differences were found in B/C pancreatic fistula rate regarding to pancreatic transection site.
CONCLUSIONS
LDP is a safe procedure, with perioperative outcomes similar to ODP and with less blood loss. The pancreatic transection site did not influence post-operative pancreatic fistula rate.

OBJECTIVE
To determine the incidence of clinically relevant postoperative pancreatic fistula (CR-POPF) following radical gastrectomy and to identify independent risk factors of CR-POPF.
BACKGROUND
CR-POPF and its sequelae are potential complications following radical gastrectomy. The reported incidence of CR-POPF was quite different across various regions, and no consensus was reached.
METHODS
Between December 2017 to November 2018, patients who underwent radical gastrectomy from 22 centers across 13 regions in China were prospectively recruited. The primary endpoint was the occurrence of CR-POPF, defined by the International Study Group of Pancreatic Fistula (ISGPF) in 2016. Clinically relevant change and short-term outcomes were recorded to diagnose and grade the POPF. Multivariate regression analyses were performed to identify independent risk factors of clinically relevant postoperative pancreatic fistula (CR-POPF).
RESULTS
A total of 2089 cases were analyzed. The incidence of biochemical leakage (BL) and CR-POPF were 19.6% and 1.1% respectively. All CR-POPF patients recovered well after appropriate treatment and no Grade C POPF were recorded. Logistic regression analysis showed pTNM III (OR, 2.940; 95% CI 1.180-7.325; P = 0.021) and LigaSure usage (OR, 6.618; 95% CI 1.847-23.707; P = 0.004) were independent risk factors of CR-POPF. LigaSure usage (OR, 4.817; 95% CI 1.184-19.598; P = 0.028), the drain amylase content (D-AMY) on postoperative day 3 (POD3) ≥5 times the upper limit of normal amylase (OR, 3.476; 95% CI 1.240-9.744; P = 0.018) and open surgery (OR, 2.463; 95% CI 1.003-6.050; P = 0.049) were independent predictors for identifying CR-POPF from BL.
CONCLUSION
In rich-experienced gastric cancer centers, there is high prevalence of BL secondary to radical gastrectomy without clinical impact. Fewer patients suffered Grade B POPF, and Grade C POPF was less common. The patients with pTNM III or LigaSure usage were prone to suffer CR-POPF. Surgery procedure, LigaSure usage combined with D-AMY measurement on POD3 are promising for early identification of CR-POPF.

Review
Pancreaticopleural fistula, an abnormal communication between the pancreas and the pleural cavity, is a rare complication of pancreatic disease in children and is mainly associated with acute pancreatitis, chronic pancreatitis, trauma or iatrogenicinjury. The present review presents the current available data concerning the pathogenesis, clinical features, diagnosis and management of this unusual but difficult clinical problem among children, in order to shed light on its pathologic manifestation and raise clinical suspicion. The review of the literature was performed through a PubMed search of pediatric original articles and case reports, using the key words "pancreaticopleural fistula", "pancreatitis", "pleural effusion", "pseudocyst" and "children". The literature search revealed 47 cases of pediatric patients with pancreaticopleural fistula. Diagnosis is based on the patient's medical history, physical examination and imaging, while the cornerstone of diagnosis is the presence of high pleural effusion amylase levels. The management of this disorder includes conservative, endoscopic and surgical treatment options. If treated promptly and properly, this clinical entity could have a lower rate of complications. The incidence of pancreaticopleural fistula in children may be underestimated in the literature, due to a reduced degree of clinical suspicion. A more heightened awareness of this entity is needed to improve the quality of life in children that suffer from this condition, as early diagnosis is essential for effective treatment and improved outcome.

BACKGROUND
Clinically relevant postoperative pancreatic fistula (CR-POPF) is a major complication of pancreatoduodenectomy (PD). A pancreatic stent is usually used for drainage of the pancreatic duct, but the best type of the stent remains unclear. The aim of this study was to investigate perioperative factors and their influence on the risk of CR-POPF following PD.
METHODS
From 2006 to 2019, the records of 246 patients who underwent PD were retrospectively reviewed, and the relationship between perioperative factors including type of pancreatic stent and CR-POPF was investigated. External or internal pancreatic stents were used for drainage of the pancreatic duct, and the internal stent was inserted 1 cm into the jejunum to decrease stent obstruction.
RESULTS
External and internal pancreatic stents were used in 137 and 109 patients, respectively. Multivariate analysis revealed that the diameter of the main pancreatic duct (odds ratio = 0.292, 95% confidence interval = 0.140-0.605, P = 0.001), diagnosis (odds ratio = 3.359, 95% confidence interval = 1.498-7.693, P = 0.003), and type of pancreatic stent (odds ratio = 0.435, 95% confidence interval = 0.203-0.934, P = 0.033) were independent factors related to CR-POPF after PD. Internal stent was associated with a low rate of CR-POPF (P < 0.001) and short postoperative hospital stay (P < 0.001) compared to external stent.
CONCLUSION
A short pancreatic internal stent could decrease the incidence of CR-POPF.

Randomized Controlled Trial
BACKGROUND
Previous studies reported a higher rate of postoperative pancreatic fistula after minimally invasive distal pancreatectomy compared to open distal pancreatectomy. It is unknown whether the clinical impact of postoperative pancreatic fistula after minimally invasive distal pancreatectomy is comparable with that after open distal pancreatectomy. We aimed to compare not only the incidence of postoperative pancreatic fistula, but more importantly, also its clinical impact.
METHODS
This is a post hoc analysis of a multicenter randomized trial investigating a possible beneficial impact of a fibrin patch on the rate of clinically relevant postoperative pancreatic fistula (International Study Group for Pancreatic Surgery grade B/C) after distal pancreatectomy. Primary outcomes of the current analysis are the incidence and clinical impact of postoperative pancreatic fistula after both minimally invasive distal pancreatectomy and open distal pancreatectomy.
RESULTS
From October 2010 to August 2017, 252 patients undergoing distal pancreatectomy were randomized, and data of 247 patients were available for analysis: 87 minimally invasive distal pancreatectomy and 160 open distal pancreatectomies. The postoperative pancreatic fistula rate after minimally invasive distal pancreatectomy was significantly higher than that after open distal pancreatectomy (28.7% vs 16.9%, P = .029). More patients were discharged with an abdominal surgical drain after minimally invasive distal pancreatectomy compared to open distal pancreatectomy (30/87, 34.5% vs 26/160, 16.5%, P = .001). In patients with postoperative pancreatic fistula, additional percutaneous catheter drainage procedures were performed less often (52% vs 84.6%, P = .012), with fewer drainage procedures (median [range], 2 [1-4] vs 2, [1-7], P = .014) after minimally invasive distal pancreatectomy.
CONCLUSION
In this post hoc analysis, the postoperative pancreatic fistula rate after minimally invasive distal pancreatectomy was higher than that after open distal pancreatectomy, whereas the clinical impact was less.

Review
With the development of imaging technology and surgical techniques, pancreatic resections to treat pancreatic tumors, ampulla tumors, and other pancreatic diseases have increased. Pancreaticoduodenectomy, one type of pancreatic resection, is a complex surgery with the loss of pancreatic integrity and various anastomoses. Complications after pancreaticoduodenectomy such as pancreatic fistulas and anastomosis leakage are common and significantly associated with patient outcomes. Pancreatic fistula is one of the most important postoperative complications; this condition can cause intraperitoneal hemorrhage, septic shock, or even death. An effective way has not yet been found to avoid the occurrence of pancreatic fistula. In most medical centers, the frequency of pancreatic fistula has remained between 9% and 13%. The early detection and routine drainage of anastomotic fistulas, pancreatic fistulas, bleeding, or other intra-abdominal fluid collections after pancreatic resections are considered as important and effective ways to reduce postoperative complications and the mortality rate. However, many recent studies have argued that routine drainage after abdominal operations, including pancreaticoduodenectomies, does not affect the incidence of postoperative complications. Although inserting drains after pancreatic resections continues to be a routine procedure, its necessity remains controversial. This article reviews studies of the advantages and disadvantages of routine drainage after pancreaticoduodenectomy and discusses the necessity of this procedure.

PURPOSE
Postoperative pancreatic fistula (POPF) is a complication discussed in the context of pancreatic surgery, but may also result from splenectomy; a relationship that has not been investigated extensively yet.
METHODS
This retrospective single-center study aimed to analyze incidence of and risk factors for POPF after splenectomy. Patient characteristics included demographic data, surgical procedure, and intra- and postoperative complications. POPF was defined according to the International Study Group on Pancreatic Surgery as POPF of grade B and C or biochemical leak (BL).
RESULTS
Over ten years, 247 patients were identified, of whom 163 underwent primary (spleen-associated pathologies) and 84 secondary (extrasplenic oncological or technical reasons) splenectomy. Thirty-six patients (14.6%) developed POPF of grade B/C or BL, of which 13 occurred after primary (7.9%) and 23 after secondary splenectomy (27.3%). Of these, 25 (69.4%) were BL, 7 (19.4%) POPF of grade B and 4 (11.1%) POPF of grade C. BL were treated conservatively while three patients with POPF of grade B required interventional procedures and 4 with POPF of grade C required surgery. POPF and BL was noted significantly more often after secondary splenectomy and longer procedures. Multivariate analysis confirmed secondary splenectomy and use of energy-based devices as independent risk factors for development of POPF/BL after splenectomy.
CONCLUSION
With an incidence of 4.5%, POPF is a relevant complication after splenectomy. The main risk factor identified was secondary splenectomy. Although POPF and BL can usually be treated conservatively, it should be emphasized when obtaining patients' informed consent and treated at centers with experience in pancreatic surgery.
