Celiac Plexus Denudation in Triangle Dissection in Pancreatico Duodenectomy: Perioperative Anesthetic Implications.

This is a case report of inadvertent right celiac plexus denudation during triangle dissection during the surgery for carcinoma of pancreas under combined general epidural anaesthesia. Operative removal of the ganglia has its own autonomic effects, which are important to observe for anesthesiologists and perioperative critical care physicians alike.

Energy utilization in cattle with steady state and non-steady state methods: the importance of thermal neutrality.

The efficiency by which animals utilize dietary energy is fundamental to the cost of production for protein of animal origin and to the carbon footprint an animal industry has. Hence, the development of cost effective methodology for determining these measurements of efficiency is important. The objective of the present study was to investigate the use of infrared thermography in a rapid, non-steady state method for measuring energy loss in cattle. Data from 241 yearling bulls and steers as well as heifers and mature cows are presented. Infrared images were collected following a 24h feed withdrawal period. The infrared thermal response in these animals was significantly ranked (P < 0.03) with conventional measurements of feed efficiency using residual feed intake values for animals demonstrated to be within a thermal neutral zone. When animals were not within a thermal neutral zone there was no significant ranking. The data suggests that the use of a non-steady state approach using infrared thermography for identifying metabolic efficiency in animals may be a more rapid and less expensive method for identifying differences in energy utilization. The data also demonstrates the importance of maintaining thermal neutrality when measuring metabolic efficiency irrespective of the methodology.

Laparoscopic Approach for Management of Hydatid Cyst of Liver.

BACKGROUND: Laparoscopy surgery trials are small and unconvincing at present and are limited to higher centers. The objective of the study is to determine the clinical features, prevalence of site of hydatid cyst and complications of this modality of this treatment. METHODS: A cross sectional study was carried out in all patients with one or two hepatic hydatid cyst who underwent laparoscopic management in KMCTH from January 2013 to March 2015 were included in the study. Aspiration, deroofing and evacuation of the hydatid cyst were done. RESULTS: Twenty six patients underwent laparoscopic management for liver hydatid cysts. Males were seven (65.38%) and females were 9(34.61%).The mean age was 35.5±13.1 years (range 21-55years.) The commonest complaint was pain and discomfort in 13(50%) patients and lump in 6(13.06%) patients. Twenty four (92.3%) patients were successfully treated with laparoscopic approach. Two (7.69%) patients had to be converted to laparotomy because of dense adhesions and bleeding. Mean operation time was 43.6±10.6 minutes. Two (7.69%) patients had port site infection. One (3.84%) patient had bile leak and no recurrence and mortality in our series. CONCLUSIONS: Laparoscopic management of liver hydatid cyst was safe and effective in selective group of patients in equipped hospital.

Effectiveness of 0.2% Glyceryl Trinitrate and 0.5% Nifedipine in the Treatment of Chronic Anal Fissure.

INTRODUCTION: Anal fissure is an ischemic ulcer caused by combination of spasm of internal anal sphincter and poor blood supply to the posterior midline of anal canal. This study aimed to assess the efficacy of Glyceryl Trinitrate and Nifedipine in the treatment of chronic anal fissure. METHODS: Ninety patients with symptomatic anal fissure in Kathmandu Medical College Teaching Hospital are allocated for study in two groups of 45 each from March 2013 to April 2014. The patients are assigned alternatively to GTN group and Nifedipine group. All patients were assessed every week till 8 weeks in regards to headache, compliance, healing and recurrence. The patients who had complete healing in 8 weeks were further followed up for 6 weeks to detect recurrence. RESULTS: Patients in the two groups were comparable in regard to demographic data (age and sex) as well as clinical factors. Headache was main complaint of patients using GTN in high percentage (16.6%) than complained by patients using topical Nifedipine (6.9%). This factor led to poor compliance with GTN compared with Nifedipine. Nifedipine showed better healing rate 82.5% compared with GTN 60%. Recurrence was comparable among the two groups. CONCLUSIONS: Nifedipine ointment showed better results than GTN ointment in chronic anal fissure regarding headache, compliance, healing and recurrence in 6 weeks of follow up period after complete healing of fissure in 8 weeks.

Visualisation of Rouviere's Sulcus during Laparoscopic Cholecystectomy.

INTRODUCTION: Safe dissection of Calot's Triangle is important during the performance of laparascopic cholucystectomy. The purpose of the study is to determine the frequency of demonstrable Rouviere's sulcus in patients with symptomatic gall stones and its role in safe dissection in Calot's triangle. METHODS: This is a prospective descriptive study design done in Department of surgery, Kathmandu Medical College Teaching Hospital from Jan 2013 to Jan 2015. Patients who were posted for laparoscopic cholecystectomy were included. During laparoscopy, Rouviere's sulcus was noted in the operative note and classified according to following: Type I: Open type was defined as a cleft in which the right hepatic pedicle was visualized and the sulcus was opened throughout its length. Type II: if the sulcus was open only at its lateral end. Type III If the sulcus was open only at its medial end. Type IV: Fused type was defined as one in which the pedicle was not visualized. RESULTS:  A total of 200 patients underwent laparoscopic cholecystectomy during period of 2 years. Out of which Rouviere's sulcus was visualized in 150 patients (75 %).Type I (open type) was commoner in 54%, type II in 12%, Type III in 9% and type IV (fused type) in 25%. CONCLUSION: Rouviere's Sulcus is an important extra biliary land mark for safe dissection of Calot's triangle during laparoscopic cholecystectomy.  KEYWORDS: Rouviere's Sulcus, Laparoscopic cholecystectomy, Bile duct injury.

Early enteral feeding in intestinal anastomosis.

BACKGROUND: Routine practice after major GI surgery has been to keep patient nil per oral till the return of bowel sound with a belief that this will prevent post operative nausea and vomiting and protect the anastomotic site where as the trend has been changing to encourage enteral feeding as soon as possible as various studies has shown early enteral feeding to be beneficial in terms of nutritional, immunological aspect and for faster recovery of patient. METHODS: Patients undergoing major elective GI surgery in department of Surgery, Kathmandu Medical college Teaching Hospital who were given early enteral feeding (within 24 hrs of operation) were studied prospectively and were compared retrospectively with historical control who underwent similar procedure. RESULTS: Early enteral feeding in patient undergoing major G.I surgery showed early return of bowel movement, decreased ICU and hospital stay with a significant reduction in postoperative cost. CONCLUSIONS: Early enteral feeding promotes faster recovery while reducing hospital stay and treatment cost in patient undergoing major GI surgery.

Single incision laparoscopic cholecystectomy vs conventional cholecystectomy in developing country.

INTRODUCTION: Use of laparoscopic surgery has demanded principles of less trauma of access hence less scar and so probably less complications. Hence conventional laparoscopic surgeries were tried with natural orifice transluminal surgery (NOTES) and then single incision laparoscopic surgery (SILS). With refinement in instruments and surgeons skills SILS have bridged up between conventional and NOTES in order to quench the desire of less or no scar at all. METHODS: Comparative case control study between conventional laparoscopic cholecystectomy and SILS in public teaching hospital. RESULTS: Total 20 patients underwent SILS cholecystectomy and 20 underwent conventional cholecystectomy and found that no difference between both in terms of post operative pain score, hospital stay and post operative wound infection except significant difference in mean operative time and patient's level of satisfaction was less in patient with SILC if were subjected to pay for instruments in order to maintain cosmesis. CONCLUSIONS: Though SILS have gained rapid acceptance in surgical fraternity, large number of randomized controlled trials are necessary to show its benefit over conventional laparoscopic cholecystectomy.

Information leaflet as an adjunct to verbal counseling in obtaining informed consent.

INTRODUCTION: This study evaluates if addition of information leaflet after the usual verbal counseling improves the level of understanding of patients undergoing surgery about their disease, the need for surgery and its complications. METHODS: It is a prospective observational case control study in which the control group receives verbal counseling only and the study group is given an information leaflet in addition to the verbal counseling after random allocation. An interviewer (surgical resident) interviews both the group using a set questionnaire. The answers are scored and added to give total marks. RESULTS: There were total 114 patients undergoing gall bladder surgery with 59 in the study group and 55 in the control group. The level of understanding was good or satisfactory in 18.2 % in the control group compared to 76.3% in the study group (P < 0.000). This statistically significant improvement was seen even among illiterate group when analyzed separately. CONCLUSIONS: Addition of information leaflet significantly improves the patients understanding of their disease irrespective of their education status.

Serum gamma glutamyl transferase and alkaline phosphatase in acute cholecystitis.

BACKGROUND: The serum level of gamma glutaryl transferase and alkaline phosphatase is raised in acute calculus cholecystitis and common bile duct stone. However, the rise in serum level of these enzymes in acute cholecystitis implies stone in the common bile duct is not well studied. Thus, it may lead to retained CBD stone on one side and unnecessary CBD exploration on the other during emergency laparoscopic cholecystectomy. The objective of the study is to predict presence of CBD stone by assessing serum level of gamma-glutamyltransferase (gamma-GT)and alkaline phosphatase. METHODS: A prospective study was designed which included 40 patients with clinically diagnosed and radiologically confirmed acute cholecystitis and 40 patients who had choledocholithiasis with or without cholangitis. Their serumgamma glutaryl transferase and alkaline phosphatase were analyzed. RESULTS: Both acute cholecystitis and CBD pathology had significant increase in alkaline phosphatase (p-value: 0.05). However, in acute cholecystitis there was 1.69±0.118 fold increase and in CBD pathology there was 2.5±0.57 fold increase in alkaline phosphatase than normal.(130 IU /L). There was no statistically significant difference ingamma- GT in both acute cholecystitis and CBD pathology(p-value: 0.390). However it increases by 2.8±0.47fold in acute cholecystitis and by 2.2±0.16 in CBD pathology(p value: 0.627). CONCLUSIONS: Although there is rise in serumγ-GT and alkaline phosphatase level in acute cholecystitis and CBD stone,only more than 2.5 fold rise in serum alkaline phosphatase level predicts CBD stone.

Influence of duration of symptoms over perioperative outcomes during emergency laparoscopic cholecystectomy.

BACKGROUND: Laparoscopic cholecystectomy is a gold standard treatment for gall stone diseases. Early surgical intervention in acute calculus cholecystitis is feasible and duration of onset of symptoms does not influence the conversion rate. OBJECTIVE: To compare the safety and feasibility between urgent and delayed laparoscopic cholecystectomy in patients with acute calculus cholecystitis. MATERIALS AND METHODS: This is a comparative study conducted in Department of Surgery, Kathmandu Medical College, during the period of January 2006 to January 2008. Alltogether, 436 patients were analysed out of which 55 were selected as urgent laparoscopic cholecystectomy and were included in the study. Among 55 patients presented with acute calculus cholecystitis were divided into two groups. Group 1 underwent laparoscopic cholecystectomy within 72 hours of onset of pain abdomen and Group 2 after 72 hours of onset of pain abdomen. RESULTS: Conversion rate in Group 1 was 19.44% whereas it was 263% in Group 2 (p = .693). There was no statistically significant difference in mean operating time (p = .412), total hospital stay (p = .626), bile duct injury and postoperative complications. CONCLUSION: Urgent laparoscopic cholecystectomy is safe and duration of onset of pain abdomen does not influence conversion rate.

Hospital based analytic study of peptic ulcer disease in patients with dyspeptic symptoms.

BACKGROUND: Peptic ulcer disease is one of the most common diseases prevalent in developing country like Nepal and with availability of endoscopy there have been increase in diagnosis and therapeutic use of endoscopy. OBJECTIVE: The aim of this study is to investigate the prevalence of peptic ulcer disease in patient who came for upper gastrointestinal endoscopy in Kathmandu Medical College Teaching Hospital. MATERIALS AND METHODS: All patients who were referred to department of endoscopy from outpatient department (OPD) and inpatient department with symptoms like dyspepsia, upper GI bleeding were included from August 2004 to August 2008. RESULTS: A total of 2761 patient were evaluated, with mean age group of 40.57 years (range 8- 95 years) and with sex distribution of male 1353 (49%) and female 1408 (51%) and racial difference into Aryan 2050 (74.2%) and Mongoloid 771 (25.8%). There were 983 patients (35.60%) with peptic disease which includes erosive gastritis, non erosive gastritis, duodenitis and gastroduodenitis without obvious ulcer. The prevalence of peptic disease with or without ulcer was more common in age group of 20- 49 years (n= 764, 27.67 %) with 70 patient with gastric ulcer (2.5%) and 50 patient with duodenal ulcer (1.8%). There was no significant racial difference among incidence of peptic ulcer (P value= 0.527). CONCLUSIONS: Peptic ulcer disease is a significant cause of morbidity in urban population of Nepal with more prevalent of erosive diseases in productive age group (20-49 years). However both male and female have equal incidence of peptic ulcer disease and there was no significant racial difference in its incidence.

The role of sedation and pulse oximetry during upper gastrointestinal endoscopy.

INTRODUCTION: To determine the changes in oxygen saturation, blood pressure and pulse rate during endoscopic procedure and to evaluate--oesophagogastroduodenoscopy (OGD) related discomfort assessed by the patient. METHODS: It is observational case control study. Baseline pulse, blood pressure and oxygen saturation were monitored before procedure, at one minute of procedure, at five minute and soon after procedure. Patients were randomly selected according to lottery system (1: without sedation and 2: with sedation) and divided into two groups; without and with sedation. Before leaving department they were asked about level of discomfort during and after procedure. RESULTS: Patient's mean age +/- SD: 36.65, +/- 11.42 years and 53.3% were men. Base line mean oxygen saturation among sedated patient were 96.77 +/-1.56 % and 97.23, +/- 2.26 % respectively (P = 0.358). Mild to moderate hypoxia was noted more in sedated patient than in non sedated patient. Severe hypoxia was noted in 3.3% of sedated patient. No statistically significant change was noticed in pulse and blood pressure in both the group. None or only slight discomfort was experienced by 9.4% in non sedated group and 90.6% in sedated group. Severe discomfort by 96.4% in non sedated group and 3.6% in sedated group. CONCLUSIONS: There is slight more incidence of mild hypoxia in sedated group than in non sedated group but no change in pulse and blood pressure. However, sedated patient have significant less level of discomfort than in non sedated group. Though routine use of pulse oxymeter is not necessary, routine use of sedation during endoscopy is recommended.

Inguinal vasal obstruction following polypropylene mesh repair.

Inguinal vasal obstruction following hernia repair is related to either direct injury to vas or ischemic injury leading to delay stricture. Not much has been described regarding the long term impact of synthetic mesh as far as integrity of the cord structure is concerned. Here, we report a case that underwent mesh explantation for posthernioplasty inguinodynia as well as recurrence and found to have total occlusion of the lumen of vas segment adherent to the explanted mesh on microscopic examination.
