TG13 guidelines for diagnosis and severity grading of acute cholangitis (with videos)

Since the publication of the Tokyo Guidelines for the management of acute cholangitis and cholecystitis (TG07), diagnostic criteria and severity assessment criteria for acute cholangitis have been presented and extensively used as the primary standard all over the world. However, it has been found that there are crucial limitations in these criteria. The diagnostic criteria of TG07 do not have enough sensitivity and specificity, and its severity assessment criteria are unsuitable for clinical use. A working team for the revision of TG07 was organized in June, 2010, and these criteria have been updated through clinical implementation and its assessment by means of multi-center analysis. The diagnostic criteria of acute cholangitis have been revised as criteria to establish the diagnosis where cholestasis and inflammation demonstrated by clinical signs or blood test in addition to biliary manifestations demonstrated by imaging are present. The diagnostic criteria of the updated Tokyo Guidelines (TG13) have high sensitivity (87.6 %) and high specificity (77.7 %). TG13 has better diagnostic capacity than TG07. Severity assessment is classified as follows: Grade III: associated with organ failure; Grade II: early biliary drainage should be conducted; Grade1: others. As for the severity assessment criteria of TG07, separating Grade II and Grade I at the time of diagnosis was impossible, so they were unsuitable for clinical practice. Therefore, the severity assessment criteria of TG13 have been revised so as not to lose the timing of biliary drainage or treatment for etiology. Based on evidence, five predictive factors for poor prognosis in acute cholangitis--hyperbilirubinemia, high fever, leukocytosis, elderly patient and hypoalbuminemia--have been extracted. Grade II can be diagnosed if two of these five factors are present. Free full-text articles and a mobile application of TG13 are available via http://www.jshbps.jp/en/guideline/tg13.html.

TG13 surgical management of acute cholecystitis

BACKGROUND

Laparoscopic cholecystectomy is now accepted as a surgical procedure for acute cholecystitis when it is performed by an expert surgeon. There are several lines of strong evidence, such as randomized controlled trials (RCTs) and meta-analyses, supporting the introduction of laparoscopic cholecystectomy for patients with acute cholecystitis. The updated Tokyo Guidelines 2013 (TG13) describe the surgical treatment for acute cholecystitis according to the grade of severity, the timing, and the procedure used for cholecystitis in a question-and-answer format using the evidence concerning surgical management of acute cholecystitis.

METHODS AND MATERIALS

Forty-eight publications were selected for a careful examination of their full texts, and the types of surgical management of acute cholecystitis were investigated using this evidence. The items concerning the surgical management of acute cholecystitis were the optimal surgical treatment for acute cholecystitis according to the grade of severity, optimal timing for the cholecystectomy, surgical procedure used for cholecystectomy, optimal timing of the conversion of cholecystectomy from laparoscopic to open surgery, and the complications of laparoscopic cholecystectomy.

RESULTS

There were eight RCTs and four meta-analyses concerning the optimal timing of the cholecystectomy. Consequently, it was found that cholecystectomy is preferable early after admission. There were three RCTs and two meta-analyses concerning the surgical procedure, which concluded that laparoscopic cholecystectomy is preferable to open procedures. Literature concerning the surgical treatment according to the grade of severity could not be quoted, because there have been no publications on this topic. Therefore, the treatment was determined based on the general opinions of professionals.

CONCLUSION

Surgical management of acute cholecystitis in the updated TG13 is fundamentally the same as in the Tokyo Guidelines 2007 (TG07), and the concept of a critical view of safety and the existence of extreme vasculobiliary injury are added in the text to call the surgeon's attention to the need to reduce the incidence of bile duct injury.

TG13 indications and techniques for gallbladder drainage in acute cholecystitis (with videos)

Percutaneous transhepatic gallbladder drainage (PTGBD) is considered a safe alternative to early cholecystectomy, especially in surgically high-risk patients with acute cholecystitis. Although randomized prospective controlled trials are lacking, data from most retrospective studies demonstrate that PTGBD is the most common gallbladder drainage method. There are several alternatives to PTGBD. Percutaneous transhepatic gallbladder aspiration is a simple alternative drainage method with fewer complications; however, its clinical usefulness has been shown only by case-series studies. Endoscopic naso-gallbladder drainage and gallbladder stenting via a transpapillary endoscopic approach are also alternative methods in acute cholecystitis, but both of them have technical difficulties resulting in lower success rates than that of PTGBD. Recently, endoscopic ultrasonography-guided transmural gallbladder drainage has been reported as a special technique for gallbladder drainage. However, it is not yet an established technique. Therefore, it should be performed in high-volume institutes by skilled endoscopists. Further prospective evaluations of the feasibility, safety, and efficacy of these various approaches are needed. This article describes indications and techniques of drainage for acute cholecystitis.Free full-text articles and a mobile application of TG13 are available via http://www.jshbps.jp/en/guideline/tg13.html.

TG13 miscellaneous etiology of cholangitis and cholecystitis

This paper describes typical diseases and morbidities classified in the category of miscellaneous etiology of cholangitis and cholecystitis. The paper also comments on the evidence presented in the Tokyo Guidelines for the management of acute cholangitis and cholecystitis (TG 07) published in 2007 and the evidence reported subsequently, as well as miscellaneous etiology that has not so far been touched on. (1) Oriental cholangitis is the type of cholangitis that occurs following intrahepatic stones and is frequently referred to as an endemic disease in Southeast Asian regions. The characteristics and diagnosis of oriental cholangitis are also commented on. (2) TG 07 recommended percutaneous transhepatic biliary drainage in patients with cholestasis (many of the patients have obstructive jaundice or acute cholangitis and present clinical signs due to hilar biliary stenosis or obstruction). However, the usefulness of endoscopic naso-biliary drainage has increased along with the spread of endoscopic biliary drainage procedures. (3) As for biliary tract infections in patients who underwent biliary tract surgery, the incidence rate of cholangitis after reconstruction of the biliary tract and liver transplantation is presented. (4) As for primary sclerosing cholangitis, the frequency, age of predilection and the rate of combination of inflammatory enteropathy and biliary tract cancer are presented. (5) In the case of acalculous cholecystitis, the frequency of occurrence, causative factors and complications as well as the frequency of gangrenous cholecystitis, gallbladder perforation and diagnostic accuracy are included in the updated Tokyo Guidelines 2013 (TG13).

TG13 diagnostic criteria and severity grading of acute cholecystitis (with videos)

Since its publication in 2007, the Tokyo Guidelines for the management of acute cholangitis and cholecystitis (TG07) have been widely adopted. The validation of TG07 conducted in terms of clinical practice has shown that the diagnostic criteria for acute cholecystitis are highly reliable but that the definition of definite diagnosis is ambiguous. Discussion by the Tokyo Guidelines Revision Committee concluded that acute cholecystitis should be suspected when Murphy's sign, local inflammatory findings in the gallbladder such as right upper quadrant abdominal pain and tenderness, and fever and systemic inflammatory reaction findings detected by blood tests are present but that definite diagnosis of acute cholecystitis can be made only on the basis of the imaging of ultrasonography, computed tomography or scintigraphy (HIDA scan). These proposed diagnostic criteria provided better specificity and accuracy rates than the TG07 diagnostic criteria. As for the severity assessment criteria in TG07, there is evidence that TG07 resulted in clarification of the concept of severe acute cholecystitis. Furthermore, there is evidence that severity assessment in TG07 has led to a reduction in the mean duration of hospital stay. As for the factors used to establish a moderate grade of acute cholecystitis, such as leukocytosis, ALP, old age, diabetes, being male, and delay in admission, no new strong evidence has been detected indicating that a change in the criteria used in TG07 is needed. Therefore, it was judged that the severity assessment criteria of TG07 could be applied in the updated Tokyo Guidelines (TG13) with minor changes. TG13 presents new standards for the diagnosis, severity grading and management of acute cholecystitis.

Interns' perspectives about communicating bad news to patients: a qualitative study

INTRODUCTION

Communicating bad news to patients and families is an essential skill for physicians but can be difficult for interns. Very little is known about skills in this area for interns in developing countries.

METHOD

Two focus groups, consisting of a total of 12 interns, were conducted in the Seth G.S. Medical College and KEM Hospital in Mumbai, India. The grounded theory approach was used to identify common themes and concepts, which related to: (1) barriers in communicating bad news, (2) interns' confidence in communicating bad news, (3) interns' perceptions about their need for such training and (4) interns' suggested methods for training.

RESULTS

Interns described barriers in time constraints, language, their personal fears, patients' illiteracy, crowded wards with no privacy and lack of training. All interns lacked confidence in breaking news of death, but seven were confident in breaking bad news about chronic diseases or cancers. Subjects reported they had received very little classroom teaching or formal instruction in this area, though they had had opportunities to observe a few instances of breaking bad news. They expressed need for increased focus on communication skills curriculum in the form of case discussions, workshops and small group teaching, in addition to clinical observation.

CONCLUSIONS

Interns in our school in Mumbai reported inadequate training and low comfort and skill in communicating bad news and expressed need for focused training.

Effectiveness of box trainers in laparoscopic training

RATIONALE AND OBJECTIVES

Various devices are used to aid in the education of laparoscopic skills ranging from simple box trainers to sophisticated virtual reality trainers. Virtual reality system is an advanced and effective training method, however it is yet to be adopted in India due to its cost and the advanced technology required for it. Therefore, box trainers are being used to train laparoscopic skills. Hence this study was undertaken to assess the overall effectiveness of the box-training course. STUDY PROCEDURE: The study was conducted during six-day laparoscopic skills training workshops held during 2006. Twenty five surgeons; age range of 26 to 45 years, of either sex, who had not performed laparoscopic surgery before; attending the workshop were evaluated. Each participant was given a list of tasks to perform before beginning the box-training course on day one and was evaluated quantitatively by rating the successful completion of each test. Evaluation began when the subject placed the first tool into the cannula and ended with task completion. Two evaluation methods used to score the subject, including a global rating scale and a task-specific checklist. After the subject completed all sessions of the workshop, they were asked to perform the same tasks and were evaluated in the same manner. For each task completed by the subjects, the difference in the scores between the second and first runs were calculated and interpreted as an improvement as a percentage of the initial score.

STATISTICAL ANALYSIS

Wilcoxon matched-paired signed-ranks test was applied to find out the statistical significance of the results obtained.

RESULTS

The mean percentage improvement in scores for both the tasks, using global rating scale, was 44.5% ± 6.930 (Mean ± SD). For task 1, using the global rating scale mean percentage improvement was 49.4% ± 7.948 (Mean ± SD). For task 2, mean percentage improvement using global rating scale was 39.6% ± 10.4 (Mean ± SD). Using Wilcoxon matched-paired signed-ranks test, 2-tailed P-value<0.0001 which is extremely significant.

CONCLUSION

This study confirms that a short-term, intensive, focused course does improve laparoscopic skills of trainees. Box-trainers can be used to change the present day didactic training into objective and competency-based. Global rating scale and checklist provide an inexpensive and effective way of objective assessment of performance of laparoscopic skills.

Laparoscopic splenectomy using conventional instruments

Introduction:

Laparoscopic splenectomy (LS) is an accepted procedure for elective splenectomy. Advancement in technology has extended the possibility of LS in massive splenomegaly [Choy et al., J Laparoendosc Adv Surg Tech A 14(4), 197–200 (2004)], trauma [Ren et al., Surg Endosc 15(3), 324 (2001); Mostafa et al., Surg Laparosc Endosc Percutan Tech 12(4), 283–286 (2002)], and cirrhosis with portal hypertension [Hashizume et al., Hepatogastroenterology 49(45), 847–852 (2002)]. In a developing country, these advanced gadgets may not be always available. We performed LS using conventional and reusable instruments in a public teaching the hospital without the use of the advanced technology. The technique of LS and the outcome in these patients is reported.

Materials and Methods:

Patients undergoing LS for various hematological disorders from 1998 to 2004 were included. Electrocoagulation, clips, and intracorporeal knotting were the techniques used for tackling short-gastric vessels and splenic pedicle. Specimen was delivered through a Pfannensteil incision.

Results:

A total of 26 patients underwent LS. Twenty-two (85%) of patients had spleen size more than 500 g (average weight being 942.55 g). Mean operative time was 214 min (45–390 min). The conversion rate was 11.5% (n = 3). Average duration of stay was 5.65 days (3–30 days). Accessory spleen was detected and successfully removed in two patients. One patient developed subphrenic abscess. There was no mortality. There was no recurrence of hematological disease.

Conclusion:

Laparoscopic splenectomy using conventional equipment and instruments is safe and effective. Advanced technology has a definite advantage but is not a deterrent to the practice of LS.

Ergonomics in laparoscopic surgery

Laparoscopic surgery provides patients with less painful surgery but is more demanding for the surgeon. The increased technological complexity and sometimes poorly adapted equipment have led to increased complaints of surgeon fatigue and discomfort during laparoscopic surgery. Ergonomic integration and suitable laparoscopic operating room environment are essential to improve efficiency, safety, and comfort for the operating team. Understanding ergonomics can not only make life of surgeon comfortable in the operating room but also reduce physical strains on surgeon.

Intraoperative localization of vascular malformation of small bowel by selective intra-arterial dye injection

Angiomatous malformation is the most common vascular abnormality, accounting for 30-40% cases of obscure GI bleeding from small bowel. Surgical resection is the treatment of choice in severe or recurrent hemorrhage requiring multiple blood transfusions. However, the diffuse nature of the lesions poses a challenge to localize them accurately preoperatively, for exact resection. We present a case in which we have used selective mesenteric angiography with selective cannulation and exact localization of the lesion by injecting dye such as methylene blue, indigo carmine, and fluorescein, to localize the angiomatous malformation before surgical resection and also to determine the exact resection to be done.

Laparoscopic training in India: need for criterion-based training and objective assessment of surgical skills

Over the past 2 decades, laparoscopic techniques have evolved from diagnostic laparoscopy to more complex procedures. Minimally invasive techniques are routinely used for bariatric, colonic and advanced gastrointestinal surgical procedures. These new techniques require highly developed psychomotor skills and place an extra demand upon surgeons to acquire, maintain and develop a wide range of operative skills in the middle of their careers. In developed countries, training is imparted in skills centres, which use various models not only to teach a skill, but also as a means of assessment, both of technical competence and of decision-making. In addition, these centres are playing an expanding role in providing credentials to surgeons and maintaining the standards of skills. In India, laparoscopic training for community surgeons is unstructured and opportunistic, while resident's training is not uniform. There is a need for structured training programmes that include giving residents and community surgeons experience in skills laboratories, alongwith an objective assessment of acquired skills.

Influence of timing on performance of laparoscopic cholecystectomy for acute biliary pancreatitis

AIM

Gallstone disease is the most common cause of acute pancreatitis. Cholecystectomy is mandatory to avoid recurrence of pancreatitis. Our objective was to evaluate the results of laparoscopic cholecystectomy (LC) in patients with gall-stone induced pancreatitis.

METHODS

All patients presenting to us within the time frame from February 2004 to June 2008 with acute biliary pancreatitis were included in the study. The severity of pancreatitis was assessed by Ranson's criteria. ERCP and endoscopic sphincterotomy was performed when the common bile duct (CBD) was dilated (>6 mm) with either calculi or sludge as seen on imaging. Patients with successful ERCP with predicted demanding laparoscopic cholecystectomy were discharged instead for an elective LC, 4-6 weeks later. Patients with mild pancreatitis (with Ranson's score of 3 or less) and predicted uncomplicated LC underwent surgery at the same admission. The difficulty of the procedure was determined by the presence of adhesions in the gallbladder area, dissection in Calot's triangle, tackling the dilated cystic duct, intra-operative bleeding, and the need for a drain.

RESULTS

A total of 26 patients (12 male and 14 female; age range 23-75 years) with acute biliary pancreatitis comprised the study group. Eleven patients with suspected choledocholithiasis underwent ERCP and clearance of the CBD was done in all of them. Nine patients (2 ERCP and 7 non-ERCP) underwent early LC in the same admission. Seventeen patients (9 ERCP and 8 non-ERCP) were predicted as difficult cases for LC and underwent delayed LC. No patient had recurrent pancreatitis in the interval period.

CONCLUSION

There was no significant difference in the operative difficulty between early and delayed LC when patients were selected for timing of LC based on pre-defined criteria.

Varied presentations of gastrointestinal stromal tumour

Gastrointestinal stromal tumours (GIST) are soft tissue tumours arising from the mesenchyma in the gastrointestinal tract. These are rare tumours. However, over the past few years with the better understanding of the pathogenesis of GIST and better imaging facilities, the diagnosis is made more frequently. The characteristic diagnostic feature of GIST is the expression of CD34 and receptor tyrosine kinase KIT, CD117 by these tumours. The use of tyrosine kinase inhibitor imatinib mesylate has led to improved outcome. The presentation of GIST however remains non-specific, and varies depending upon the size and the organ of origin. We present a series of four cases of GIST with varied presentation.

Networking in medical education: creating and connecting

Social networking is being increasingly used as a tool of choice for communications and collaborations in business and higher education. Learning and practice become inseparable when professionals work in communities of practice that create interpersonal bonds and promote collective learning. Individual learning that arises from the critical reconstruction of practice, in the presence of peers and other health professionals, enhances a physician's capability of clinical judgment and evidence-based practice. As such, it would be wise for medical schools, whose responsibility it is to prepare students to make a transition to adult life with the skills they need to succeed in both arenas, to reckon with it.

Mucormycosis of the bile duct: a case report

A case of isolated localised mucormycosis of the bile duct in an immuno-competent 54 year old female patient is described. Mucormycosis is rare in immuno-competent patients. Isolated localised mucormycosis of the bile duct has not yet been described in the literature.

Spectrum and outcome of pancreatic trauma

BACKGROUND AND AIMS

Pancreatic trauma is associated with high morbidity and mortality. Diagnosis is often difficult and surgery poses a formidable challenge.

METHOD

Data from 17 patients of pancreatic trauma gathered from a prospectively maintained database were analysed and the following parameters were considered: mode of injury, diagnostic modalities, associated injury, grade of pancreatic trauma and management. Pancreatic trauma was graded from I through IV, as per Modified Lucas Classification.

RESULTS

The median age was 39 years (range 19-61). The aetiology of pancreatic trauma was blunt abdominal trauma in 14 patients and penetrating injury in 3. Associated bowel injury was present in 4 cases (3 penetrating injury and 1 blunt trauma) and 1 case had associated vascular injury. 5 patients had grade I, 3 had grade II, 7 had grade III and 2 had grade IV pancreatic trauma. Contrast enhanced computed tomography scan was used to diagnose pancreatic trauma in all patients with blunt abdominal injury. Immediate diagnosis could be reached in only 4 (28.5%) patients. 7 patients responded to conservative treatment. Of the 10 patients who underwent surgery, 6 required it for the pancreas and the duodenum. (distal pancreatectomy with splenectomy-3, pylorus preserving pancreatoduodenectomy-1, debridement with external drainage-1, associated injuries-duodenum-1). Pancreatic fistula, recurrent pancreatitis and pseudocyst formation were seen in 3 (17.05%), 2 (11.7%) and 1 (5.4%) patient respectively. Death occurred in 4 cases (23.5%), 2 each in grades III and IV pancreatic trauma.

CONCLUSIONS

Contrast enhanced computed tomography scan is a useful modality for diagnosing, grading and following up patients with pancreatic trauma. Although a majority of cases with pancreatic trauma respond to conservative treatment, patients with penetrating trauma, and associated bowel injury and higher grade pancreatic trauma require surgical intervention and are also associated with higher morbidity and mortality.

Role of computed tomography in the diagnosis of rib and lung involvement in tuberculous retromammary abscesses

OBJECTIVE

To assess the role of computed tomography (CT) in the diagnosis of rib and lung involvement in tuberculous abscess in the retromammary region.

DESIGN AND PATIENTS

Eight patients with tuberculous retromammary abscess were examined by CT and the findings were evaluated. A cold abscess (purulent collection with absence of acute inflammation) was aspirated in all cases. Diagnosis was confirmed by acid-fast bacillus culture, or histologic examination.

RESULTS

CT showed a relatively well marginated, inhomogeneous, hypodense lesions in all eight cases. Following administration of intravenous contrast medium, these lesions showed enhancing walls, suggestive of an infective collection. Lung involvement was seen in one patient. A direct communication from the retromammary lesion through the thoracic wall into the pleura was seen in five cases. In four cases destroyed rib fragments within the abscess were noted.

CONCLUSION

A tuberculous abscess in the retromammary region is usually shown on CT as a focal, well-marginated, inhomogeneous, hypodense lesion with a surrounding enhancing rim. A direct communication with the pleura, a destroyed rib fragment in the abscess, and associated lung involvement may be revealed by CT.

Laparoscopic orchidectomy for undescended testis in adults

BACKGROUND

Impalpable testis is a significant diagnostic and therapeutic challenge in adults, for both radiologist and surgeons, with few reports in literature addressing this problem in adults. Laparoscopy is a reliable and definitive procedure obviating the necessity of advance investigation and subsequent inguinal exploration in adults.

AIMS

To study the utility of laparoscopy as combined diagnostic and therapeutic modality for undescended testis in adults.

SETTINGS AND DESIGN

Prospective study from a single surgical unit of a large tertiary referral centre during August 2000 to January 2002.

METHODS AND MATERIAL

Nine patients of unilateral undescended testis with average age 22.7 years (range 13-31 years) underwent diagnostic laparoscopy and orchidectomy subsequent to detailed clinical, ultrasound and examination under anaesthesia (EUA) procedure. All patients were operated with one 10 mm umbilical camera port, one suprapubic port and 1 lateral port.

RESULTS

None of the patients had palpable testis or an inguinal cough impulse on clinical examination and during EUA. In only 3(33.3%) patients, the ultrasound could locate the testis situated at the deep ring. On laparoscopy all testes were identified, 4 were present at the deep ring, 3 were intra-abdominal and 2 had blind ending vas entering the deep ring. Mesh plug was inserted in the internal ring in these 2 patients, after dissecting the peritoneum. None of the patients had intra or post-operative complications and all were discharged on the next day.

CONCLUSION

Laparoscopy is one of the most satisfactory methods for the diagnosis and management of non-palpable testis in adult cryptorchid patients.

Necrotising perineal infection: a fatal outcome of ischiorectal fossa abscesses

INTRODUCTION

Necrotizing perineal infection or Fournier's gangrene is an uncommon but lethal complication of ischiorectal fossa abscesses. It is associated with a high mortality, especially in diabetics and immunocompromised individuals. Attempts have been made to study factors which could serve as prognostic indicators. The role of faecal diversion has not been clearly determined.

MATERIALS AND METHODS

The medical records of 8 patients who presented with necrotizing perineal infection as a complication of ischiorectal fossa abscesses were reviewed. Various parameters were studied to see if any of them could serve as predictors of outcome. Mean surface area of involvement was calculated using modified burns assessment criteria. To study the effect of colostomy on the general condition of the patient the physiological and biochemical parameters before and after the procedure were compared. Statistical analysis was done using the unpaired and paired 't' tests.

RESULTS

The mean age of the patients was 50.6 +/- 10.3 years. Five patients were diabetic, of whom four died; all the non-diabetics survived. The mean surface area of involvement was 5.1 +/- 0.75%, among the survivors, and 9.6 +/- 3.4% among the non-survivors. Colostomy was performed in four patients one of whom died. While in one patient the colostomy was created along with the initial radical debridement, in three other patients it was formed on days three, five and five, respectively. There was a significant improvement in their general status and biological parameters. All patients with testicular involvement died.

CONCLUSION

Evidence of systemic sepsis at presentation, extent of tissue and testicular involvement, a low haematocrit, a high blood urea and creatinine and a low serum albumin, were associated with a higher mortality. Prompt recognition of the condition, urgent radical surgical debridement and the use of appropriate antibiotics are the mainstays of management. Formation of a diverting colostomy appears to favour survival.

Paraesophageal mediastinal drainage with diversion for delayed presentation of esophageal perforation

Esophageal perforation is a serious condition; a delay of more than 48 hours in initiation of treatment leads to increased morbidity and mortality. Management of such patients is a surgical dilemma. We successfully managed 4 patients (2-iatrogenic, 1-tuberculous, 1-Boerhaave's syndrome) with delayed presentation of esophageal perforation by esophageal exclusion and paraesophageal mediastinal drainage, achieving good control of mediastinal sepsis, healing of perforation and at the same time avoiding thoracotomy and subsequent second surgery.

Giant prosthesis for reinforcement of visceral sac for complex bilateral and recurrent inguinal hernias: a prospective evaluation

AIMS

To evaluate giant prosthesis for reinforcement of visceral sac (GPRVS) as a treatment for complex bilateral and recurrent inguinal hernias.

SUBJECTS AND METHODS

The prospective study carried out in a single surgical unit at a tertiary health care center involved consecutive series of 31 patients with complex bilateral and recurrent inguinal hernias who underwent GPRVS. All were men and the mean age was 58 years (range 49-95 years). Factors predicting high risk for recurrence included a large hernia ( greater, similar5cms, 32%, 10/31 patients), failure of one or more previous repairs (45%, 14/31 patients), chronic obstructive pulmonary disease (25%, 8/31 patients) and poor muscle tone (70%, 22/31 patients). Operative time, length of postoperative stay, complications and death were the main outcome measures.

RESULTS

Mean -/+ SEM operative time was 65 -/+ 11 minutes (range 45-115 minutes). Mean -/+ SEM length of stay was 3.5 -/+ 0.7 days (range 2-5 days). There were 4 minor complications, but no mesh infections and death. Follow up was obtained for a mean period of 14.6 months (range 12-23 months); there were no recurrences.

CONCLUSION

GPRVS provides a definitive and safe cure for repair of complex bilateral and recurrent inguinal hernias because of its simplicity, ease of the procedure, good results and low recurrence rate.

Shouldice's herniorrhaphy versus Moloney's darn herniorrhaphy in young patients (a prospective randomised study)

AIMS

Shouldice's repair (SR) and Moloney's darn repair (DR) are commonly practised repairs for hernias in the young age group with acceptably low recurrence rates. The SR is considered technically challenging and difficult, while the DR is gaining popularity in recent years. Therefore, there is a need to compare these repairs.

MATERIAL AND METHODS

To compare these techniques a total of 50 cases (age group 18-40 years) were randomised to two groups (SR 25, DR 25). These were well matched for age, the side and the type of hernia. Both groups were studied with respect to operative time; postoperative pain at 6,12 and 24 hours (evaluated by pain scale 1-10) need for analgesia, ambulation (evaluated by a four-point scale), complications and return to work.

RESULTS

The SR required a longer time (average 81 minutes) compared to DR (average 43 minutes). Patients undergoing SR complained of pain of a higher scale at 6, 12 and 24 hours post surgery and had a significant higher need for analgesia on day 1 and 2 (p < 0.05). Ambulation grades were significantly better in the DR group on the first postoperative day (p < 0.05). There was no significant difference in the two groups with respect to postoperative complications, return to work, and recurrences rate (2-year follow-up).

CONCLUSION

The SR and DR are comparable for young patients having a primary hernia. However, DR is superior in terms of the time taken, post-operative pain, need for analgesia and early ambulation.

Spontaneous oesophageal perforation due to mediastinal tuberculous lymphadenitis - atypical presentation of tuberculosis

Spontaneous non-traumatic oesophageal perforation secondary to bursting of a mediastinal tuberculous abscess into the oesophagus is rare. The diagnosis is delayed, as perforation remains localised due to mediastinal lymph nodes. Patient can be effectively managed by paraoesophageal drainage of the mediastinal abscess and oesophageal diversion.

Synchronous primary adenocarcinoma of small and large bowel

Synchronous cancer of the small and large bowel is rare. We report a 45-year-old woman with synchronous primary cancer of the jejunum and descending colon who presented with intestinal obstruction.

A study of stress in medical students at Seth G.S. Medical College

BACKGROUND

It is usually observed that medical students undergo tremendous stress during various stages of the MBBS course. There is a high rate of suicide among them.

METHODS

To determine incidence of stress and factors controlling stress in medical students at various stages of MBBS course at Seth G S Medical college, 238 students (First year 98, Second 76, Third 64) were asked to complete a questionnaire on personal data (gender, stay at hostel, mode of travel, time spent in travel every day, medium of study in school, place of school education.), Stress inducing factors, Zung's depression scale, ways of coping, stress relievers, perceived social support and personality type. Statistical tests used were ANOVA, critical ratio and Student's 't' test.

RESULTS

Majority of medical students (175/238--73%) perceived stress. Stress was found to be significantly more in Second and Third MBBS students rather than First MBBS levels (p < 0.05). Stress was not found to differ significantly on the basis of sex, stay at hostel, model of travel, time spent in travel every day, medium of study in school, place of school education. Stress was found to be significantly more in students having more than 95% of marks at 12th Standard as compared to others. Academic factors were greater perceived cause of stress in medical students. There was no significant difference in the students at different levels of MBBS regarding academic factors and social factors as a stress inducing factors. Physical factors were found to be significantly more in Second and Third MBBS students as compared to First MBBS students. Emotional factors were found to be significantly more in First MBBS students as compared to Second & Third MBBS students. Stress was more common in medical students who have dominant strategy of coping as positive reappraisal, accepting responsibility and planful problem solving. Stress was less common in medical students at Seth G S Medical College who have dominant strategy of coping as escaping and distancing from difficult situation. Family and Friend as perceived social supports were more in Second MBBS than First MBBS medical students. Stress was not found to be significantly more in students having their personality factor contributing to stress (Type A--52/67) as compared to others (Type B--123/171). This indicates that the stress was not trait oriented but was process oriented (p = NS).

CONCLUSION

Stress in medical students is common and is process oriented. It is more in second and third year. Academic factors are greater perceived cause of stress in medical students at Seth G S medical college. Emotional factors are found to be significantly more in First MBBS. It is dependent on person's ways of coping and social support.

Fetus in fetu or a retroperitoneal teratoma--a controversy revisited. A case report and review of literature

A 25 year old man male presented with a lump in the left side of the abdomen. Ultrasonography revealed an echogenic retroperitoneal mass with hyperechoic areas within it suggestive of bone. CT scan confirmed the presence of a large retroperitoneal mass with bone within it. On exploration there was a large encapsulated retroperitoneal lump. There was a soft tissue mass within the lump surrounded by a yellow pultaceous material admixed with pus. Examination of the specimen showed a bone at the cephalic end with teeth embedded within it. There were two limb buds near the cephalic end. The whole specimen was covered with skin with all its appendages. There was coelomic cavity present. The distinction between fetus in fetus and teratoma has for long been the subject of controversy. According to the criteria described by Willis, there should be a vertebral axis present to make the diagnosis of fetus in fetu. But there have been a few reports where cases have been described as fetus in fetu even in the absence of a vertebral axis. A review of the literature concerning this controversy is briefly given.

Factors predicting morbidity and mortality in intestinal fistulae

INTRODUCTION

Intestinal fistulae are a daunting clinical problem.

AIM

To evaluate the influence of various severity factors on morbidity and mortality in patients with intestinal fistulae.

METHOD

In 29 patients with intestinal fistulae, eight severity factors, viz., age, associated bowel disease, anemia, hypoalbuminemia, high-output fistula, category IV fistula, excoriation of skin surrounding the stoma, and sepsis, were analyzed prospectively to assess their effect on healing of fistulae and mortality. Chi-squared test with Yates' correction was used.

RESULTS

Age, presence of associated bowel disease, and hemoglobin levels had no significant effect on healing or mortality. Hypoalbuminemia, category IV fistulae, presence of local skin excoriation, and sepsis significantly delayed healing (p < 0.05). High-output fistula, category IV fistula, local skin excoriation, and sepsis were significantly associated with high mortality (p < 0.05).

CONCLUSION

Identification of these prognostic factors in intestinal fistulae may guide the need for more intensive care or intervention.

Biliary sepsis: an ascending infection

AIM

To study the bacteriology of normal and obstructed biliary tree and determine the mode of biliary infection.

METHODS

Fifty seven patients undergoing elective biliary surgery for calculous biliary disease cholecystitis 45, obstructive jaundice 12) were studied. Bile samples collected separately from gall bladder, common bile duct and duodenum at the time of surgery were processed for aerobic and anaerobic cultures and antibiotic assays. To locate endogenous foci of infection, urine, nasal swab and throat swab cultures were done. Isolates from/biliary tract were compared with those from other sites.

RESULTS

Thirty eight patients (66.7%) had bactobilia. The prevalence was higher in patients with obstructive jaundice (10/12, 83.3%) than (p = 0.5) in those with non-obstructed biliary tree. Single bacterial infection (31 cases, 81 %) was more common than mixed infection (7 cases, 19%). Colonization of more than one segment of the biliary tree was seen in 30 patients (79%). E coli was the most frequently isolated organism. In 24 cases (63.2%), strains of organisms from the common bile duct and gall bladder were similar to those from the duodenum, and in only 10 cases (23.2%) were similar to those found in the nose, throat and urine. The antibiotic concentrations in the common bile duct after single doses of preoperative antibiotic (gentamicin and cephazolin) were lower in the obstructed biliary tree (1.5 +/- 0.4 milligrams/mL and 2.8 milligrams/mL respectively) than in the non-obstructed system (3.9 +/- 1.7 milligrams and 12.6 milligrams/mL/mL respectively) (p = 0.5 for both antibiotics).

CONCLUSION

Ascending infection forms the mode of biliary sepsis in a majority of cases. Prophylactic antibiotics give low levels in the bile in an obstructed biliary tree.

Laparoscopic versus mini-lap cholecystectomy for gallstone disease

AIM

To compare the outcome of laparoscopic cholecystectomy (LC) and mini-lap cholecystectomy (MC) in patients with symptomatic gallstone disease.

METHOD

One hundred patients undergoing LC (50) or MC (50) were evaluated for duration of surgery, morbidity, need for analgesia, duration of hospitalization and interval to return to normal work.

RESULTS

The mean operative time was significantly longer in the LC group (94 +/- 17 vs 129 +/- 33 min; p < 0.05). The rate of morbidity and conversion to open surgery were similar in the two groups. Patients in the MC group required more oral analgesia (p = ns). The mean post-operative hospital stay in this group was 3.3 +/- 1.5 days as compared to 3.3 +/- 2.7 days in the LC group (p = ns). Patients in the LC group took the same time to return to normal work (19.1 +/- 3.2 days) as those in the MC group 19.5 +/- 5.4 days (p = ns).

CONCLUSION

MC and LC are comparable procedures for treatment of gallstone disease in our country.

Scintigraphic detection of bile leak and follow-up in a post-cholecystectomy patient with recognition of tail sign

Early detection of site and extent of biliary tract disruption can significantly reduce mortality and morbidity in a postoperative biliary leak. We report a case in whom extent and location of post surgical biliary leak was detected with the help of 99mTc BULIDA cholescintigraphy and showed a good correlation with "T" tube cholangiography. Cholescintigraphy was also useful in assessing the follow up of this patient. We conclude that 99mTc BULIDA cholescintigraphy is a non-invasive, safe, simple and sensitive procedure in the detection of the site, extent of the leak and in follow up of the postoperative biliary leak.

Intraperitoneal abscesses: diagnostic dilemmas and therapeutic options

BACKGROUND

The diagnosis of intraperitoneal abscesses is difficult, resulting in delay in treatment and poor prognosis. Although recent advances in the management have led to significant improvement in prognosis, the choice of therapeutic modality is unclear.

AIMS

The role of clinical features and investigations in the diagnosis of intraperitoneal abscesses was studied. The relation of prognosis to delay in diagnosis was also analyzed. Also assessed was the efficacy of various therapeutic modalities.

METHODS

Thirty consecutive patients diagnosed to have intraperitoneal abscesses were analyzed. Abscesses were analyzed. Abscesses were divided on the basis of ultrasonography findings into simple and complex (with or without fecal fistula). The following points were evaluated: clinical features, and hematological, biochemical and microbiological reports, imaging findings and the role of therapeutic modalities like percutaneous aspiration (single or multiple), catheter drainage and operative drainage (transperitoneal, extraperitoneal and percutaneous).

RESULTS

Clinical features and hematological investigations, though sensitive, were non-specific in diagnosis. Klebsiella was the commonest organism cultured, followed by Proteus, E coli and Pseudomonas. Blood culture was positive in only 6 percent of cases. Real-time ultrasonography had an accuracy of 84%. Contrast X-rays were required in 43% of cases. All the deaths (4 of 30) occurred when the diagnosis and treatment were delayed by more than 4 days. USG-guided aspiration (single and multiple) and USG-guided catheter drainage were effective in simple abscesses but failed in complex abscesses. Transperitoneal operative drainage was successful in 15 of 18 cases (6 of 8 simple abscesses and 9 of 10 complex abscesses). The mortality in patients with simple and complex abscesses was 2 of 17 and 2 of 13 respectively.

CONCLUSIONS

Early detection with consequent early treatment is vital for good prognosis of intraperitoneal abscesses. Early diagnosis requires a high degree of clinical suspicion and appropriate use of imaging modalities. USG-guided percutaneous drainage is effective for simple abscesses whereas complex abscesses require operative drainage, sometimes in combination with initial USG-guided drainage.

Esophageal endoscopic sclerotherapy in children using 3% aqueous phenol

OBJECTIVE

To study the efficacy of endoscopic variceal sclerotherapy (EST) in controlling acute variceal bleeding and preventing recurrence of bleeding from esophageal varices in children.

METHODS

Ninety children (mean age 7.3 +/- 3.0 years) with portal hypertension [extra-hepatic portal venous obstruction (EHPVO) 83, cirrhosis 7] presenting with hematemesis and/or melena were subjected to EST using 3% phenol in water as sclerosant.

RESULTS

Active variceal bleeding could be controlled in 31 of 34 (91%) cases. Varices could be obliterated in 87% of patients with a mean of 5.4 +/- 2.5 injection sessions. Pre-obliteration variceal rebleeding was observed in 15% of patients. Complications such as esophageal ulceration, stricture and perforation were observed in 32%, 4.5% and 1% of patients respectively. Strictures responded to dilatation whereas perforation responded to conservative treatment. Recurrence of varices was seen in 22% of patients at a mean interval of 5.8 +/- 1.9 months. The mortality in the emergency group was 9.5% and nil in the elective group. Ten percent of patients required surgical intervention.

CONCLUSION

EST with 3% phenol in water is effective in controlling active bleeding as well as preventing recurrent bleeding from esophageal varices in children.

Effect of venous hypercarbia and hyperventilation on myocardial contractility in canine haemorrhagic shock

To study the effect of venous hypercarbia on myocardial contractility, haemorrhagic shock was produced in six healthy mongrel dogs by ex-sanguination of 15 ml of blood/kg body weight every 20 minutes till a loss of 45 ml/kg was achieved. After recording haemodynamic and respiratory parameters, the dogs were hyperventilated by positive pressure ventilation for 30 minutes and haemodynamic and blood gas parameters reassessed. During haemorrhagic shock, mean cardiac output decreased from 4.23 l min to 0.98 l min (p < 0.01), stroke index from 2.25 to 0.35 ml/kg (p < 0.05) and left ventricular stroke work index from 3.72 to 0.19 g. m/kg. The mean mixed venous pCO2 increased from 35 mmHg to 56.7 mmHg (p < 0.05). During hypoventilation, mixed venous pCO2 decreased to 40 mmHg (p < 0.05) and without any volume replacement, mean cardiac output increased 2.5 l min (P < 0.05), stroke index to 1.13 ml/kg (p < 0.05) and left ventricular stroke work index, and index of myocardial contractility, increased to 0.78 g.m/kg (p < 0.05). Thus, although hypovolaemia is the major cause of low cardiac output in haemorrhagic shock, this study shows that venous hypercarbia (which probably indicates tissue respiratory acidosis) further worsens circulatory failure by decreasing myocardial contractility. Hyperventilation improves cardiac functions and increases output by relieving tissue hypercarbia in spite of persistent hypovolaemia.

Radionuclide assessment of peritoneovenous shunt patency

Denver shunt patency can be easily assessed by sequential scintigraphy with a Gamma camera after an intraperitoneal injection of 99mTc sulphur colloid. If the shunt is patent, the tracer will be seen throughout the shunt upto it's opening into the right atrium. The following case report illustrates the application and usefulness of this procedure.

Endoscopic esophageal variceal sclerotherapy using 3% aqueous phenol

Endoscopic esophageal variceal sclerotherapy was performed in 301 patients with portal hypertension (emergency, 72 and elective, 229) using 3% aqueous phenol as sclerosant. The cause of portal hypertension was cirrhosis of the liver in 189 patients (Child's class A-48, B-66, and C-75), extrahepatic portal venous obstruction (EHPVO) in 90, and non-cirrhotic portal fibrosis in 22 patients. In the emergency group, active bleeding was controlled in 87% of cases. Re-bleeding occurred in 101 of 290 (35%) surviving patients. Obliteration of varices was achieved in 228 (84%) patients, with a mean of 5.14 +/- 2.27 sclerotherapy sessions. Of 301 patients, 29 (9.6%) had an early in-hospital mortality (30.5% in emergency and 3% in elective group), with 16 deaths due to variceal bleeding. Of the remaining 272 patients, 40 (15%) died during follow-up, of which only 11 died of variceal bleeding. Complications, such as superficial ulcers, dysphagia, and strictures, were observed in 14%, 7% of emergency, and 3% of elective patients. None of the patients developed systemic toxicity. In conclusion, 3% aqueous phenol is an effective, safe, and economical sclerosant for esophageal variceal sclerotherapy.
