Rescue from complications after pancreaticoduodenectomies at a low-volume Caribbean center:Value of tailored peri-pancreatectomy protocols

BACKGROUND Pancreaticoduodenectomy(PD)is a technically complex operation,with a re-latively high risk for complications.The ability to rescue patients from post-PD complications is as a recognized quality measure.Tailored protocols were instituted at our low volume facility in the year 2013.AIM To document the rate of rescue from post-PD complications with tailored protocols in place as a measure of quality.METHODS A retrospective audit was performed to collect data from patients who experienced major post-PD complications at a low volume pancreatic surgery unit in Trinidad and Tobago between January 1,2013 and June 30,2023.Stan-dardized definitions from the International Study Group of Pancreatic Surgery were used to define post-PD complications,and the modified Clavien-Dindo classification was used to classify post-PD complications.RESULTS Over the study period,113 patients at a mean age of 57.5 years(standard deviation[SD]±9.23;range:30-90;median:56)underwent PDs at this facility.Major complications were recorded in 33(29.2%)patients at a mean age of 53.8 years(SD:±7.9).Twenty-nine(87.9%)patients who experienced major morbidity were salvaged after aggre-ssive treatment of their complication.Four(3.5%)died from bleeding pseudoaneurysm(1),septic shock secondary to a bile leak(1),anastomotic leak(1),and myocardial infarction(1).There was a significantly greater salvage rate in patients with American Society of Anesthesiologists scores≤2(93.3%vs 25%;P=0.0024).CONCLUSION This paper adds to the growing body of evidence that volume alone should not be used as a marker of quality for patients requiring PD.Despite low volumes at our facility,we demonstrated that 87.9%of patients were rescued from major complications.We attributed this to several factors including development of rescue protocols,the competence of the pancreatic surgery teams and continuous,and adaptive learning by the entire institution,cul-minating in the development of tailored peri-pancreatectomy protocols.

Surgical relevance of anatomic variations of the right hepatic vein

BACKGROUND Variations in the anatomy of hepatic veins are of interest to transplant surgeons,interventional radiologists,and other medical practitioners who treat liver diseases.The drainage patterns of the right hepatic veins(RHVs)are particularly relevant to transplantation services.AIM The aim was to identify variations of the patterns of venous drainage from the right side of the liver.To the best of our knowledge,there have been no reports on RHV variations in in a Caribbean population.METHODS Two radiologists independently reviewed 230 contrast-enhanced computed tomography scans performed in 1 year at a hepatobiliary referral center.Venous outflow patterns were observed and RHV variants were described as:(1)Tributaries of the RHV;(2)Variations at the hepatocaval junction(HCJ);and(3)Accessory RHVs.RESULTS A total of 118 scans met the inclusion criteria.Only 39%of the scans found conventional anatomy of the main hepatic veins.Accessory RHVs were present 49.2%and included a well-defined inferior RHV draining segment VI(45%)and a middle RHV(4%).At the HCJ,83 of the 118(70.3%)had a superior RHV that received no tributaries within 1 cm of the junction(Nakamura and Tsuzuki type I).In 35 individuals(29.7%)there was a short superior RHV with at least one variant tributary.According to the Nakamura and Tsuzuki classification,there were 24 type II variants(20.3%),six type III variants(5.1%)and,five type IV variants(4.2%).CONCLUSION There was significant variation in RHV patterns in this population,each with important relevance to liver surgery.Interventional radiologists and hepatobiliary surgeons practicing in the Caribbean must be cognizant of these differences in order to minimize morbidity during invasive procedures.

Right hepatectomy with a cholangiojejunostomy and hepaticojejunostomy for unilobar Caroli’s syndrome

Choledochal cysts are benign cystic dilatations of the extra-and intrahepatic bile ducts[1,2].If untreated,their sequelae include recurrent cholangitis,secondary biliary cirrhosis,acute pancreatitis,and cholangiocarcinoma[3,4].Todani et al.[5]classified choledochal cysts into 5 subtypes,of which type V is Caroli’s disease.The disease is either localized,where unilobar biliary dilatation,commonly in the left,is present,or diffuse,where the entire liver is involved.

Faecal incontinence and health related quality of life in inflammatory bowel disease patients: Findings from a tertiary care center in South Asia

AIM: To analyze the frequency and severity of faecal incontinence(FI) and its effect on the quality of life(QOL) in inflammatory bowel disease(IBD) patients. METHODS: All patients who attended surgical and medical gastroenterology outpatient clinics in a tertiary care center with an established diagnosis of either ulcerative colitis(UC) or Crohn's disease(CD) over a period of 10 mo were included in this study. Before enrollment into the study, the patients were explained about the study and informed consent was obtained. The patients with unidentified colitis were excluded. The data on demographics, disease characteristics, FI(Vaizey score), and quality of life(IBD-Q) were collected. Data were analyzed using SPSS version 21.RESULTS: There were 184 patients(women = 101, 54.9%; UC = 153, 83.2%) with a female preponderance for UC(male/female ratio = 1:1.5) and a male preponderance for CD(male/female = 2:1). Forty-eight(26%) patients reported symptoms of FI. Among the patients with FI, 70.8% were women(n = 34) and 29.2% were men(n = 14) with an average age of 52.7 years(range, 20-78 years). Average age of onset of FI was 48.6(range, 22-74) years. Ten percent(n = 5) reported regular FI. Incontinence to flatus was seen in 33.3%(n = 16), to liquid faeces in 56.2%(n = 27), to solid faeces in 6.2%(n = 3) and to all three in 4.1%(n = 2). Twenty-one percent(n = 10) complained of disruption of their physical and social activity. There was no association between FI and type of IBD. Significant associations were found between FI and age(P = 0.005) and gender(P < 0.001). QOL in our cohort of patients was significantly affected by FI.CONCLUSION: In our study, nearly a quarter of patients reported FI. There was a significant correlation between FI and QOL. Therefore, enquiring about FI in IBD patients can lead to identification of this debilitating condition. This will enable early referral for continence care in this group of patients.

Whipple’s operation with a modified centralization concept:A model in low-volume Caribbean centers

Conventional data suggest that complex operations,such as a pancreaticoduodenectomy(PD),should be limited to high volume centers.However,this is not practical in small,resource-poor countries in the Caribbean.In these settings,patients have no option but to have their PDs performed locally at low volumes,occasionally by general surgeons.In this paper,we review the evolution of the concept of the high-volume center and discuss the feasibility of applying this concept to low and middle-income nations.Specifically,we discuss a modification of this concept that may be considered when incorporating PD into low-volume and resource-poor countries,such as those in the Caribbean.This paper has two parts.First,we performed a literature review evaluating studies published on outcomes after PD in high volume centers.The data in the Caribbean is then examined and we discuss the incorporation of this operation into resource-poor hospitals with modifications of the centralization concept.In the authors’opinions,most patients who require PD in the Caribbean do not have realistic opportunities to have surgery in high-volume centers in developed countries.In these settings,their only options are to have their operations in the resource-poor,low-volume settings in the Caribbean.However,post-operative outcomes may be improved,despite low-volumes,if a modified centralization concept is encouraged.

Pain relief in upper abdominal malignancy

The symptom of cancer most feared by many patients is pain. The physical and psychological distress of constant pain without relief should not be underestimated, and all complaints of pain should be actively treated. The clinician should not forget however that drugs used in the treatment of

Changing clinical profile,management strategies and outcome of patients with biliary tract injuries at atertiary care center in SriLanka

BACKGROUND: Biliary tract injuries are mostly iatrogenic Related data are limited in developing countries. There are lessons to be learned by revisiting the clinical profiles management issues and outcome of patients referred to a tertiary care center in Sri Lanka, compared with the previous data from the same center published in 2006. Such a review is particularly relevant at a time of changing global perceptions of iatrogenic biliary injuries. This study aimed to analyze and compare the changes in the injury pattern, management and outcome following biliary tract injury in a Sri Lankan study population treated at a tertiary care center. METHODS: A retrospective analysis was made of 67 patients treated between May 2002 and February 2011. The profiles of the last 38 patients treated from October 2006 to February 2011 were compared with those of the first 29 patients treated from May 2002 to September 2006. Definitive management options included endoscopic biliary stenting, reconstructive hepaticojejunostomy with creation of gastric access loops and biliary stricture dilation. Post-treatment jaundice cholangitis and abdominal pain needing intervention were considered as treatment failures. RESULTS: In the 67 patients, 55 were women and 12 men Their mean age was 40.6 (range 19-80) years. Five patients had traumatic injuries. Thirty-seven injuries (23 during the second study period) were due to laparoscopic cholecystectomy and 25 (10 during the second study period) to open cholecystectomy The identification rate of intra-operative injury was 19% in the laparoscopic group and 8% in the open group. Bismuth typeI, II, III and IV injuries were seen in 18, 18, 15 and 12 patients, respectively. Endoscopic stenting was the definitive treatment in 20 patients. In 35 patients who had hepaticojejunostomy, 33 underwent creation of the gastric access loop. Twenty- two reconstructions were performed during the second study period. A gastric access loop was used for endotherapy in three patients with anastomotic occlusion at the site of hepaticojejunostomy. The overall outcome was satisfactory in the majority of patients. There were four injury-related deaths. CONCLUSIONS: Biliary tract injuries associated with laparoscopic cholecystectomy have become the most frequent cause of biliary injury management at our center. Although endotherapy was useful in selected patients, in the majority, surgical reconstruction with hepaticojejunostomy was required as the definitive treatment. Creation of the gastric access loop was found to be a useful adjunct in the management of hepaticojejunostomy strictures.
