Background Idiopathic orbital inflammatory pseudotumor (IOIP) is a commom orbital disease,with serious eye symptoms and replase tendency,and its pathogenesis is still unclear.Nuclear factor-κB (NF-κB)-related proteins participate in many important pathophysiological process,however,whether NF-κB plays a role in the IOIP process is worthy of attention.Objective This study was to explore the roles of NF-κB pathway in IOIP pathogenesis.Methods Twenty-four IOIP specimens were collected during surgery in Beijing Tongren Hospital from September 2010 to May 2016.The histopathological characteristics of IOIP were examined by hematoxylin and eosin staining.The expression and location of NF-κB/p65,p-p65,p50 and inhibitor of κB (IκB-ot) were detected by immunohistochemistry and verified by immunocytochemistry and Western blot assay.Results The histopathological features of IOIP were numerous small lymphocyte infiltraion and fibrous tissue proliferation,and a lot of epithelioid cells were seen in lacrimal gland-involved specimens.NF-κB/p65 was positively expressed in the cytoplasm of all 24 specimens and the nucleus in 15 specimens with the expressing rate of 62.5％.p50 was expressed in the cytoplasm in 22 specimens with the expressing rate of 91.7％ and in the nucleus in 17 specimens with the expressing rate of 70.8％.The positive expression of p-p65 was found in 22 specimens with the expressing rate of 91.7％,and IκB-α was expressed in the cytoplasm of 11 specimens with the expressing rate of 45.8％.These results were confirmed by immunocytochemistry and Western blot assay.Conclusions NF-κB pathway is activiated during IOIP process,and NF-κB pathway may be involved in the pathogenesis of IOIP.

Objective:To summarize the technical points of laparoscopic pancreaticoduodenectomy (LPD) carried out in a single center.Methods:The clinical data of 102 patients who underwent laparoscopic pancreaticoduodenectomy in 2018 at the Department of Hepatobiliary Surgery of the Second Hospital of Hebei Medical University were retrospectively analyzed, and the general conditions, operation time, intraoperative blood loss, and surgical operation were analyzed. Post-operative complications, hospital stay and other indicators were studied.Results:Of the 102 patients who were included, there were 57 males and 45 females, aged 15.0 to 79.0 (59.9±11.8) years old, with a body mass index (23.6±3.6) kg/m 2. For the 102 patients who underwent LPD, 6 were total pancreatic resection. Three were combined with vascular resection in the form of portal vein-superior mesentery vein segmental resection. The operation time was (376.6±87.2) min, the intraoperative blood loss was 350 (100, 800) ml, and the postoperative hospital stay was (17.0±5.9) days. Postoperative complications occurred in 26 of the 102 patients (25.5%), and more than two complications occurred in 17 patients. B/C grade pancreatic fistula occurred in 9 patients (9.4%), abdominal bleeding in 8 patients (7.8%), gastrointestinal bleeding in 2 patients (2.0%), biliary fistula in 4 patients (3.9%), and gastric emptying disorder in 5 patients (4.9%), 8 patients had pulmonary infection (7.8%). Five patients (4.9%) died during the perioperative period. Conclusion:The main technical points of LPD included en bloc resection, pancreaticojejunostomy, and vascular reconstruction. The basis of LPD is en bloc resection. Combined resection and reconstruction of vascular segments is a sign of maturity of LPD technology and a prerequisite for further development as a routine procedure.

Objective:To study the clinical characteristics and management strategies of late bleeding after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of 58 patients with post-pancreaticoduodenectomy hemorrhage (PPH) admitted to the Department of Hepatobiliary Surgery of the Second Hospital of Hebei Medical University from March 2018 to March 2022 were retrospectively analyzed, including 42 males and 16 females, aged (61.88±11.02) years old. According to the occurrence of intra-abdominal erosion factors (e.g., pancreatic fistula, biliary fistula, gastrointestinal anastomotic fistula, intra-abdominal abscess), patients were divided into the erosion group ( n=42) and non-erosion group ( n=16). All patients underwent standard lymphadenectomy. Clinical data including the PPH time-point, occurrence of rebleeding, and treatment outcomes were accessed. The management strategies of PPH in the two groups of patients were analyzed. Results:The PPH time-point in the erosion group and non-erosion patients was 8.00 (5.00, 19.25) d and 21.50 (12.75, 26.75) d, respectively ( P=0.001). PPH can occurred within one month after surgery in both erosion and non-erosion groups. In the erosion group, 31 cases (73.81%, 31/42) were treated by re-operation, two (4.76%, 2/42) by interventional radiology and nine (21.43%, 9/42) with conservative protocol, respectively. In the non-erosion group, five cases (31.25%, 5/16) were treated by re-operation, seven (43.75%, 7/16) by interventional radiology and four (25.00%, 4/16) with conservative protocol, respectively. The incidence of re-bleeding is higher in the erosion group [47.6% (20/42) vs 12.5% (2/16), P<0.05]. Clinical manifestations, sites and severity of bleeding, and treatment outcomes were also different in the erosion and non-erosion groups (all P<0.05). Conclusions:The occurrence of intra-abdominal erosion factors can affect the clinical characteristics and treatment strategy of late bleeding after laparoscopic pancreaticoduodenectomy. Surgery remains the treatment of choice for post-pancreaticoduodenectomy hemorrhage either as an urgent or last resort.
