Trans gastric sinus stent placement and drainage in management of persistent external pancreatic fistula / 中华肝胆外科杂志

Objective:To study the use of trans gastric sinus stent placement and drainage in management of persistent external pancreatic fistula.Methods:The clinical data of 12 patients who developed persistent external pancreatic fistulae after severe acute pancreatitis, pancreatic trauma or pancreatic surgery who were treated at the First Medical Center of Chinese PLA General Hospital from August 2018 to December 2020 were retrospectively analyzed. There were 10 males and 2 females, aged 30 to 65 years, median 43.5 years. These patients underwent trans gastric sinus stent placement and drainage, and were followed-up to study persistence of pancreatic fistula, new pancreatic fluid accumulation, complications and death.Results:In this study, there were 9 patients who developed persistent external pancreatic fistulae after severe acute pancreatitis, 2 patients after pancreatic trauma, and 1 patient after pancreatic surgery. The median operation time was 47 min (range 38-54 min). The technical success rate was 100.0% (12/12). The median follow-up was 22.5 months (range 2-29 months). Seven days after stenting, the percutaneous drainage tubes (urinary catheters) of all the patients were removed. One patient (8.3%) developed recurrence of pancreatic fistula 17 days after treatment. The same procedure of placing another stent was done and the patient recovered. Six months after treatment, 2 patients (16.7%) lost their stents, and 1 patient developed a pseudocyst (recurrence of pancreatic fistula). The maximum diameter of this pseudocyst increased gradually to 7cm after 9 months. A double pigtail drainage tube was placed under endoscopy in this patient, and the patients recovered. All the other patients did not develop recurrence of pancreatic fistula or pseudocyst. During the follow-up period, no patient developed any new complications including pancreatic fluid accumulation, fever, bleeding, infection and organ dysfunction, and no patients died.Conclusion:It was safe and efficacious to use trans gastric sinus stent placement for treatment of persistent external pancreatic fistula. However, the long-term outcomes require further studies.

Pancreatic fistula and mortality after surgical management of pancreatic trauma: analysis of 81 consecutive patients during 11 years at a Korean trauma center

PURPOSE: Pancreatic trauma is infrequent because of its central, deep anatomical position. This contributes to a lack of surgeon experience and many debates exist about its standard care. This study aimed to investigate the postoperative pancreatic fistula (POPF) and mortality of pancreatic trauma after operation. METHODS: We reviewed records in the trauma registry of our institution submitted from January 2006 to December 2016. The grade of pancreatic injury, surgical management, morbidity, mortality, and other clinical variables included in the analyses. RESULTS: Data from a total of 26,072 trauma patients admitted to the Emergency Department were analyzed. Pancreatic trauma was observed in 114 of these patients (0.44%). Laparotomy was performed in 81 patients (2 pan creatico duodenectomies, 2 pancreaticogastrostomies, peripancreatic drainage in 41 patients, distal pancreatectomies in 34 patients, and 9 patients who underwent surgery for damage control). The incidence of POPF was 38.3%. The overall mortality was 8.8% (7 of 81). In multivariate analysis, pancreas injury grade IV (≥4) (adjusted odds ratio [AOR], 4.071; P = 0.029) and preoperative peritonitis signs (AOR, 2.903; P = 0.039) were independent risk factors for POPF. All patients who died had also another major abdominal injury (≥grade 3). Multiorgan failure was a major cause of death (6 of 7, 85.7%). The mortality rate of isolated pancreas injury was 0%. CONCLUSION: The pancreas injury grade and preoperative peritonitis were significant risk factors of POPF. The mortality rate of isolated pancreatic trauma was very low.

Pancreatite crônica: resultados do tratamento cirúrgico em 74 pacientes / Results of the surgical management of 74 patients with Chronic pancreatitis

OBJETIVO: Analisar as indicações, técnicas e resultados do tratamento cirúrgico de 74 pacientes operados por complicações da pancreatite crônica. MÉTODO: Foram pacientes consecutivos, estudados prospectivamente pelo preenchimento de um protocolo individual, no período de 1971 a 2000. Foram realizadas cirurgias de derivação e ressecção. O acompanhamento foi feito pelo agendamento de consultas no ambulatório, por convocação por cartas e telefonemas. RESULTADOS: Dos 270 pacientes com pancreatite crônica, acompanhados pelo Serviço, 74 (27,4 por cento) foram operados. Destes 74 pacientes, 97,7 por cento eram do sexo masculino e a idade variou de 15 a 63 anos, com média de 39,4 anos para alcoolistas e 33,1 para aqueles com outras etiologias. O alcoolismo foi a causa da doença em 68 pacientes (90,5 por cento) e os outros casos estiveram relacionados a hiperparatiroidismo(1), pancreatite hereditária (1), fibrose retroperitoneal (1) e em três casos a etiologia não foi definida. As seguintes causas únicas ou associadas definiram a indicação cirúrgica:1. dor em 44,6 por cento dos pacientes; 2. compressão de vias biliares em 28,4 por cento; 3. pseudocistos em 12,2 por cento; 4. fístulas internas em 10,8 por cento. Cinqüenta pacientes (67,5 por cento) foram submetidos a operações de derivação e 24 (32,5 por cento) a cirurgias de ressecção. Oito pacientes derivados (16,0 por cento) complicaram, ocorrendo três óbitos; dez ressecados (41,6 por cento) complicaram, com cinco óbitos. Os óbitos estiveram relacionados a abscessos, às deiscências e às hemorragias cirúrgicas. CONCLUSÕES: As cirurgias de derivação mostraram-se mais seguras e as complicações que evoluíram com infecção foram as mais graves e ocorreram com mais freqüência nas ressecções.

BACKGROUND: To evaluate the indications, methods and results of the surgical treatment of 74 patients operated on for chronic pancreatitis complications. METHOD: Consecutive patients' charts were studied prospectively, during the years of 1971 to 2000. Surgery was indicated for pain, billiary tract stricture, pseudocysts, pancreatic ascitis and pancreaticopleural fistulas. Pancreaticojejunal anastomosis, billiary tract derivations and resections were performed. Follow-up was achieved through ambulatorial appointments or by mail and telephone calls. RESULTS: Of 270 patients listed with chronic pancreatitis, 74 (27.4 percent) were operated on. 97.7 percent of them were males. Patients varied in age from 15 to 63 years old, with an average of 39.4 years for alchoolists and 33.1years for those with pancreatitis of other etiologies. The disease was caused by alchool in 68 patients (90.5 percent). The other causes were: hyperparathyroidism (1), hereditary pancratitis (1), retroperitoneal fibrosis(1) and in three patients the etiology was unknown. Indications for surgery were: 1. Pain in 44.6 percent of the patients; 2. Billiary tract stricture (28.4 percent); 3.Pseudocysts (12.2 percent); 4. Pancreatic ascitis and pancreaticopleural fistulas (10.8 percent). Derivations were performed in 50 patients (67.5 percent), and resections in 24 (32.5 percent). Complications ocurred in eight patients with five hospital deaths related to abscesses, suture leaking and surgical bleeding. CONCLUSIONS: There was less morbidity and mortality for derivations and than after resections.
