Endoscopic Sphincterotomy for Cholecysto-Choledocholithiasis Complicates Subsequent Laparoscopic Cholecystectomy: A Retrospective Report From Sri Lanka.

OBJECTIVE: Published literature so far has supported the fact that patients who underwent endoscopic retrograde cholangio-pancreatography and sphincterotomy (ERCPS) had a difficult perioperative course after subsequent laparoscopic cholecystectomy. Through a retrospective study, this original report mentions statistics in a Southeast Asian population comparing the effect on conversion to open surgery in patients undergoing laparoscopic cholecystectomy after ERCPS in a university hospital in Sri Lanka. METHODS: The results of 205 patients who underwent laparoscopic cholecystectomy and 85 patients who were converted to open surgery between 2016 and 2018 were analyzed to find out whether ERCPS is a risk factor for conversion or subsequent perioperative morbidity. RESULTS: Demographics like age, gender and previous abdominal surgeries were comparable between the two groups. Cholecysto-choledocholithiasis and undergoing ERCPS for it were significant factors associated with conversion to open cholecystectomy. CONCLUSION: Performing laparoscopic cholecystectomy after ERCPS for cholecysto-choledocholithiasis is a significant challenge and preferably should be often handled by a more experienced surgeon.

Main title - Socio-economic effects on informal caregivers of long-term hospitalized adult patients: A cross-sectional study.

Introduction: A significant proportion of patients are being treated at hospitals in the government sector in Sri Lanka. Informal caregivers play a major role in taking care of hospitalized surgical patients while facing physical, social, and psychological challenges. Objective: To describe the socio-economic effects on informal caregivers of long-term hospitalized adult patients. Methods: A cross-sectional descriptive study was conducted among 202 informal caregivers of long-term hospitalized patients in a tertiary care hospital in Sri Lanka, using an interviewer-administered questionnaire. Sociodemographic assessment of both caregiver and care recipient, the health status of the care recipient, effects on social life, and economic aspect of informal caregiver were assessed. Results: Most of the caregivers were married (n=164, 81.2%), first degree relative of the care receiver (n=139, 68.8%), employed (n=115, 56.9%) and sole caregivers (n=130, 64.4%). Four out of 5 caregivers (n=181, 89.6%) showed moderate to severe socio-economic maladaptation. Increasing age (p=0.00), marital status (p=0.00) and sole caregiving (p=0.01) are significantly associated with the level of maladaptation. Conclusion: Moderate to severe levels of maladaptation is present among a substantial number of informal caregivers of long-term hospitalized patients. Sole caregiving is one of the contributing factors and can be addressed by adequate formal caregivers appointed by health care authorities or from voluntary services to minimize informal caregiver burnout.

Lymphangioma of the jejunal mesentery and jejunal polyps presenting as an acute abdomen in a teenager.

Cystic lymphangioma of the small bowel mesentery is a rare clinical entity, especially after childhood. Medical literature reveals a limited number of such cases presenting as acute abdomen due to bowel obstruction, small bowel volvulus and bleeding into the tumour. We present the management experience of an 18-year-old woman who presented with rapid onset diffuse peritonism and raised inflammatory markers. Computed tomography showed a mass in the small bowel mesentery with suspicion of segmental bowel ischaemia. Emergency laparotomy revealed a mass in the mid-jejunal mesentery close to the bowel wall with no bowel ischaemia. The patient made an uncomplicated recovery after segmental bowel resection and end-to-end anastomosis. Histology confirmed the mass as a cystic lymphangioma involving the jejunal mesentery and two small jejunal polyps. Lymphangioma could be considered in the differential diagnosis of an acute abdomen in a young adult when the presentation is atypical.

Two synchronous malignant tumors of the pancreas: a case report.

BACKGROUND: Only a limited number of multiple synchronous primary malignancies of the pancreas have been reported in the medical literature. We report a case of two solid malignant tumors of the pancreas diagnosed preoperatively. CASE PRESENTATION: We describe a 65-year-old Sri Lankan woman who presented with progressive obstructive jaundice. Initial contrast-enhanced computed tomography imaging detected a malignant tumor at the tail of her pancreas. A second tumor of the pancreatic head was detected with integrated imaging using multidetector computed tomography and multimodal magnetic resonance imaging. She underwent total pancreaticoduodenectomy and splenectomy. Gross examination of the specimen confirmed the presence of two separate tumors. Histology of the ampullary tumor showed pancreatic-type adenocarcinoma and the tumor in the tail of her pancreas showed a colloid-type adenocarcinoma. CONCLUSION: The possibility of multiple primary malignant solid tumors of different types with malignant potential has to be considered even without background pathology when managing multiple tumors in the pancreas.

Extra-ampullary Peutz-Jeghers polyp causing duodenal intussusception leading to biliary obstruction: a case report.

BACKGROUND: Duodenal Peutz-Jeghers polyp is a rare cause of duodenal or biliary obstruction. However, a sporadic Peutz-Jeghers polyp leading to simultaneous biliary and duodenal obstruction has not been reported. CASE PRESENTATION: We report a case of a 25-year-old Sri Lankan woman presenting with features of recurrent upper small intestinal obstruction and biliary obstruction. She had clinical as well as biochemical evidence of intermittent biliary obstruction. Evidence of duodenal intussusception was found in a computed tomography enterogram and a duodenal polyp was noted as the lead point. Marked elongation and distortion of her lower common bile duct with intrahepatic duct dilatation was also noted and the ampulla was found to be on the left side of the midline pulled toward the intussusceptum. Open polypectomy and reduction of intussusception were done and she became fully asymptomatic following surgery. Histology of the resected specimen was reported as a typical "Peutz-Jeghers polyp". As there was not enough evidence to diagnose Peutz-Jeghers syndrome this was considered to be a sporadic Peutz-Jeghers polyp. CONCLUSION: Rare benign causes such as a duodenal polyp should be considered and looked for in initial imaging, when the cause for concurrent biliary and intestinal obstruction is uncertain, particularly in young individuals.

A sonographic scoring system to assess the risk of thyroid malignancy.

Prediction of thyroid malignancy with fine needle aspiration cytology or individual ultrasound characteristics has several limitations. This study evaluates the usefulness of a combination of ultrasound characteristics in predicting malignancy in patients with thyroid nodules. We assessed 189 thyroid nodules using ultrasonography and histology. Each nodule was assigned a score based on ultrasonographic characteristics. This score was compared with histology to identify ability to predict malignancy. There were 28 malignant nodules. The scoring system was appropriate for clinical use, obtaining an area under ROC curve of 0.822 [p< 0.0001] 95% confidence. FNAC of nodules with a score of more than 4 can be recommended (100% sensitivity). Nodules with a score less than 8 can be offered total thyroidectomy when FNAC is inconclusive (97.5% sensitivity). A combination of ultrasonographic criteria increase the accuracy of predicting malignancy in thyroid nodules.

Evaluation of bactericidal effect of three antiseptics on bacteria isolated from wounds.

OBJECTIVE: Antiseptics are widely used in wound management to prevent or treat wound infections due to their proven wound healing properties regardless of their cytotoxicity. The objective of this study was to determine the bactericidal effects of three antiseptics on pathogens known to cause wound infections. METHOD: The study was carried out at a tertiary care hospital and a university microbiology laboratory in Sri Lanka in 2013. The three acids (acetic acid, ascorbic acid and boric acid) in increasing concentration (0.5%, 0.75% and 1%) were tested against bacterial suspensions equivalent to 0.5 McFarland standard. The Bacteria isolates used were isolated from wound and standard strains of Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. RESULTS: There were 33 (68.8%) Coliforms, 10 (20.8%) Pseudomonas species, and 5 (10.4%) strains of Staphylococcus aureus. Acetic acid at concentration of 0.5% inhibited growth of 37 (77%) and 42 (87.5%) of tested isolates when exposed for 30 and 60 minutes, respectively. However 100% inhibition was achieved at four hours. At a concentration of 0.75%, 40 (83.3%) and 44 (91.7%) were inhibited when exposed for 30 and 60 minutes, respectively, with 100% inhibition at 4 hours. At concentration of 1%, 46 (95.8%) inhibition was seen at 30 minutes and 100% inhibition at 60 minutes. Ascorbic acid, at 0.5% and 0.75 % concentrations, inhibited growth of 45(93.7%) and 47(97.9%) of isolates respectively when exposed for 30 minutes. At these two concentrations, 100% inhibition was achieved when exposed for one hour. At 1% concentration, 100% inhibition was achieved at 30 minutes. Boric acid did not show bactericidal effect at concentrations of 0.5%, 0.75 % and 1%. Pseudomonas species were inhibited at 30 minutes by 0.5% acetic acid. Bactericidal effect against all the standard strains was seen with three acids at each concentration tested from 30 minutes onwards CONCLUSION: Ascorbic acid was bactericidal for all organisms tested within the shortest exposure time at the lowest concentration compared to other two acids. Despite promising bactericidal effects, further studies warrant, as ongoing debates on toxicity of acids on tissue epithelialisation. Application of antiseptics for a shorter duration could overcome this problem without losing bactericidal activity. DECLARATION OF INTEREST: The authors have no conflict of interest and no funding was received for this study.

Pringle manoeuvre versus selective hepatic vascular exclusion: outcome of a case series in a tertiary referral centre.

A retrospective comparative study was done to compare the outcome of intermittent Pringle manoeuvre (IPM) and selective hepatic vascular exclusion (SHVE) in 19 major hepatectomies in non-cirrhotic patients that were done from October 2003 to June 2009. Intra-operative blood loss (IBL), total operative time (TOT) and immediate outcome were assessed in the two groups. Thirteen underwent IPM and the others underwent SHVE. The mean age was 50 years (SHVE) and 39.2 years (IPM). Mean IBL was 641 ml and 802 ml in the SHVE and IPM groups respectively (p > .05). TOT was 4.7 hours in both groups. There was one mortality from myocardial infarction in the IPM group and no morbidities in both groups. The results obtained from this study shows that IPM is equivalent to SHVE, with regards to IBL, TOT and immediate outcome in major hepatectomies in non-cirrhotic patients.

Therapeutic value and outcome of gastric access loops created during hepaticojejunostomy for iatrogenic bile duct injuries.

BACKGROUND AND PURPOSE: Hepaticojejunostomy is the reconstructive procedure performed for iatrogenic bile duct injuries. Anastomotic site stricture is the most significant complication of this operation. Revision surgery is associated with a significant morbidity and mortality. Creation of access to the anastomotic site facilitates the management of such strictures by minimal access techniques and reduces the need for revision surgery. This retrospective study aims to investigate the technical accessibility, usefulness, morbidity related to and the outcome of hepaticojejunostomy with gastric access loops performed as the treatment for iatrogenic bile duct injuries. METHODOLOGY: Twenty-seven consecutive patients who have undergone hepaticojejunostomy (including three revision surgeries and a re-revision surgery) with gastric access loops from July 2005 to October 2009 were followed up for clinical, biochemical, radiological and endoscopic evidence of anastomotic site occlusion and the need for intervention. Morbidity related to gastric access loops was assessed by dyspepsia disability score. RESULTS: Mean follow up was 35.4 (range 6-61) months. Three patients developed anastomotic strictures at 4, 22 and 5 months after hepaticojejunostomy and had successful endotherapy via the gastric access loop. They remain well at 33rd, 31st and 3rd months, respectively, following intervention. Based on the dyspepsia disability score none of the patients had symptomatic dyspepsia affecting daily activities. CONCLUSIONS: Gastric access loop is accessible and useful for stricture dilation and other endotherapeutic procedures. In the absence of significant symptoms related to bile reflux, gastric access loop could be considered as a useful and safe adjunct in the management of hepaticojejunostomy by surgeons especially in settings with limited facilities and expertise for radiological manipulations.

(131)I-MIBG radionuclide therapy is safe and cost-effective in the control of symptoms of the carcinoid syndrome.

BACKGROUND: The standard treatment used to control the symptoms of carcinoid syndrome (CS) involves subcutaneous injections of the somatostatin analogue octreotide. This is expensive (US $8000--16,000 per year), and treatment may be for many years. The aim of this study was to evaluate the efficacy and cost-effectiveness of our experience over the last 5 years with 1-131-labelled metaiodobenzylguanidine (MIBG) radionuclide therapy in the palliation of patients with CS. METHODS: A consecutive series of 20 symptomatic patients (referred between 1994 and 1999) with CS were evaluated. Fifteen of them underwent(123)I-MIBG scanning. Of the 13 patients with significant tracer uptake in metastatic deposits compared to background, 12 underwent a course of therapeutic(131)I-MIBG (one patient refused). Symptoms, biochemical markers, CT scans, follow-up(123)I-MIBG scans, and the requirement for octreotide were used to assess outcome of treatment. Costs of(131)I-MIBG and octreotide treatments were compared. RESULTS: MIBG treatment was well tolerated in all with only transient side-effects. Ten patients showed a measurable clinical improvement. Seven had a complete clinical response. The mean duration of response was 15.4 months. Octreotide was not required or was reduced in eight patients. Treatment with(131)I-MIBG resulted in a saving of US $1000 per patient, with effective symptom control, when compared to octreotide. CONCLUSION: 1-131 MIBG therapy is a safe and cost-effective therapeutic option to successfully control symptoms in patients with carcinoid syndrome.
