Percutaneous Chemical and Mechanical Necrosectomy for Walled-Off Pancreatic Necrosis.

PURPOSE: To test the hypothesis that percutaneous combined chemical and mechanical necrosectomy using a Malecot anchor drain and an Arrow-Trerotola percutaneous thrombolytic device (PTD) in patients with walled-off pancreatic necrosis (WOPN) is feasible, safe, and effective compared with a control group undergoing mechanical necrosectomy alone. MATERIALS AND METHODS: In a retrospective analysis, patients with WOPN not amenable to endoscopic-guided cystogastrostomy placement were studied as case and control groups. The patients in the case group underwent percutaneous combined chemical (hydrogen peroxide 3%) and mechanical necrosectomy using a Malecot anchor drain and/or Arrow-Trerotola PTD from December 2020 to April 2022. The controls underwent mechanical necrosectomy alone without chemical necrosectomy. Clinical success was defined as complete resolution of the cavity on follow-up noncontrast computed tomography scans with subsequent drain removal. RESULTS: Thirteen patients in the case group and 11 patients in the control group underwent percutaneous drain placement followed by percutaneous combined chemical and mechanical necrosectomy (case group) or mechanical necrosectomy only (control group) for WOPN. Drain placement and necrosectomy were technically successful in all patients studied. One patient in the case group developed postprocedural sepsis because of communication between the cavity and the splenic vein. Another patient in the case group developed bleeding from a branch of the pancreaticoduodenal artery on postnecrosectomy day 9, which was successfully embolized by interventional radiology. No pancreaticocutaneous fistula was reported at the 3-month follow-up. The clinical success rates in the case and control groups were 100% and 38.4%, respectively (P = .003). CONCLUSIONS: Percutaneous combined chemical and mechanical necrosectomy is a feasible, safe, and effective treatment of WOPN.

A Novel Approach to Managing a Strangulated De Garengeot's Hernia.

De Garengeot's hernia, the presence of an incarcerated vermiform appendix within a femoral hernia, is a rare general surgery emergency that predominantly affects elderly female patients. Due to its rarity, there is significant variation in surgical technique; however, most case reports favor an open approach. Here we present a case of a De Garengeot's hernia with a unique hybrid open and laparoscopic repair, utilizing the hernia defect as a port site. We will also review the relevant literature.

Frailty assessment in the acute care surgery population - the agreement and predictive value on length of stay and re-admission of 3 different instruments in a prospective cohort.

BACKGROUND: We compared the Emergency General Surgery Specific Frailty Index (EGSFI), Risk Analysis Index (RAI-C) and the Katz Index (KI) at assessing frailty in acute care surgery (ACS). METHODS: A prospective cohort of ACS patients was stratified into frail or non-frail by the EGSFI, RAI-C and KI. The agreement between scales were compared. RESULTS: Of 272 eligible patients, 72, 75, and 56 were categorized as frail by the EGSFI, RAI-C, and KI respectively. There was weak to no agreement between instruments and consensus among all three scales was 59.4%. CONCLUSION: Between 21 and 28% of patients seen in this ACS cohort were categorized as frail using the EGSFI, RAI-C and KI. These frailty tools have different measures of what constitutes frailty and there was poor agreement between them. Only the KI definition of frailty was associated with a longer LOS. The KI may be more useful for assessing ACS patients in a tertiary care facility.

Cholecystitis.

Cholecystitis is the most prevalent surgical condition affecting populations in industrialized countries. Rather than a single clinical entity, cholecystitis is a class of related disease states with different causes, degrees of severity, clinical courses, and management strategies. Appropriate care of the patient who has a diseased gallbladder requires a broad understanding of the acute, chronic, and acalculous cholecystitis syndromes, and awareness of their particular clinical nuances and potential complications.

Distal splenorenal shunt: preferred treatment for recurrent variceal hemorrhage in the patient with well-compensated cirrhosis.

HYPOTHESIS: Distal splenorenal shunt (DSRS) is a safe and effective treatment for patients with Child-Pugh class A and B cirrhosis with recurrent variceal hemorrhage after failed transjugular intrahepatic portosystemic shunt. DESIGN: Retrospective case review. SETTING: Hepatobiliary surgery and liver transplantation department in a tertiary referral medical center. PATIENTS: Between August 1, 1985, and May 1, 2005, 119 patients with Child-Pugh class A and B cirrhosis underwent DSRS for recurrent variceal hemorrhage. Of these, 17 (14.3%) had thrombosed or failing transjugular intrahepatic portosystemic shunt prior to DSRS. INTERVENTION: Distal splenorenal shunt for recurrent variceal hemorrhage after failure of conservative management. MAIN OUTCOME MEASURES: Morbidity, mortality, and subsequent liver transplantation rate. RESULTS: The overall perioperative morbidity rate was 31.5%. Thirteen patients (11.7%) developed encephalopathy and 6 (5.4%) had recurrent variceal hemorrhage. Other complications included portal vein thrombosis, pancreatitis, pancreatic pseudocyst, pneumonia, and wound infection. The 30-day operative mortality rate was 6.4% (n = 7). The 1-year survival rate was 85.9%. The incidence of DSRS for failed transjugular intrahepatic portosystemic shunt during the first 12 years of the study (1985-1997) was 11.1% (9/81). This proportion increased to 26.7% (8/30) during the second half of the study (1997-2005). During the 20-year period, 15 patients (13.5%) underwent liver transplantation a mean of 5.1 years after DSRS without an increase in morbidity or mortality after transplantation. CONCLUSIONS: Distal splenorenal shunt may be the preferred treatment for recurrent variceal hemorrhage in the patient with well-compensated cirrhosis. In addition, DSRS does not cause increased morbidity or mortality in subsequent liver transplantation.

Hepatobiliary surgery: lessons learned from live donor hepatectomy.

The liver is unique in the rapid tissue regeneration occurs after resection or injury, and affords the surgeon the opportunity to safely remove up to 60% to 70% of the liver volume for treatment of cancer or for use as a live donor graft for transplantation. The complex development of the liver and biliary system in utero results in multiple and complicated anatomic variations. The hepatobiliary surgeon of today must be able to integrate a broadening array of radiologic and liver resection techniques that may improve patient safety and surgical outcome. Equally important is the ability to quickly recognize postoperative complications so that prompt intervention can be instituted. Successful outcome requires a balance between sound judgement, technical acumen, and attention to detail. Herein, we provide lessons learned from live donor liver transplantation that are directly applicable to any patient undergoing major hepatic resection.
