Retrospective Research of Cases of Oral Mucosal Diseases: Diagnosis and Management Trends.

Objective: The purpose of this retrospective study was to look into patterns in the diagnosis and treatment of oral mucosal disorders over a 12-year period in a tertiary care environment. Methods: A comprehensive review of medical records from a Tertiary Care Center was conducted, encompassing 2010-2022. Data on patient demographics, clinical presentations, diagnostic methods, treatment modalities, and outcomes were systematically analyzed. Descriptive statistics and trend analyses were employed to discern patterns and changes over time. Results: A total of 500 cases were included in the research, with a mean age of 42.5 years. Aphthous ulcers, oral lichen planus, and candidiasis were the predominant diseases, collectively constituting 58% of cases. Diagnostic modalities varied, including biopsy and imaging. Treatment modalities ranged from topical agents to surgical procedures, tailored to specific diagnoses. The prevalence of squamous cell carcinoma was noteworthy at 8%. Conclusion: This research provides insights into the evolving landscape of oral mucosal disease diagnosis and treatment in tertiary care. Identified trends emphasize the importance of individualized care, advancements in diagnostic techniques, and ongoing research collaboration. Addressing challenges identified in this research is crucial for enhancing patient outcomes and shaping future research directions.

Pseudobowel perforation following endoscopic retrograde cholangiopancreatography.

We report two cases of pneumoperitoneum following endoscopic retrograde cholangiopancreatography for retained common bile duct (CBD) stones. These post-cholecystectomy patients underwent sphincterotomy, CBD clearance, and "T" tube removal at the same time. Post-procedure, both of the patients developed pneumoperitoneum. Pneumoperitoneum developed as a result of air traversing from the duodenum to the peritoneum through the ruptured "T" tube tract. "T" tube removal in the same sitting as sphincterotomy and CBD clearance may lead to pneumoperitoneum, which can be managed conservatively.

Antimicrobial susceptibility patterns of organisms causing secondary abdominal infections in patients with perforated abdominal viscus.

BACKGROUND: Secondary peritonitis, following intestinal perforation, constitutes a significant proportion of cases admitted as a surgical emergency and has a mortality rate of 6-21% worldwide. As a part of an antimicrobial stewardship program, we noted considerable variation among the choice of empirical regimens among such cases. Hence, we conducted a prospective study to generate the evidence for a rational empiric regimen for patients with secondary peritonitis following intestinal perforation. METHODS: The study included a complete follow up of 77 cases of secondary peritonitis admitted during a 12 month period. The intraoperative fluid (peritoneal) sample of the patient was sent for culture and sensitivity pattern analysis. RESULTS: The sites of perforation as seen in decreasing order were lower gastrointestinal (GI) (50.6%), upper GI (36.4%), and unclassified (13%). The most common organism found in the intraoperative fluid was Escherichia coli (47.9%) followed by Klebsiella pneumoniae (12.5%). amikacin, cefoperazone-sulbactam, piperacillin-tazobactam and imipenem were sensitive in 22 (out of 23 tested), 5 (out of 9), 13 (out of 13) and 22 (out of 22) isolates of E. coli and 3 (out of 6), 1 (out of 3), 4 (out of 6), 4 (out of 6) isolates of K. pneumoniae, respectively. The most common empirical antibiotic was cefoperazone-sulbactam (38.7%) followed by piperacillin-tazobactam (29.3%). CONCLUSION: Based on our prospective study, piperacillin-tazobactam or imipenem should be used empirically in patients presenting with complicated intra-abdominal infections secondary to perforated viscus, especially if they have sepsis or septic shock.

Placement of 0.5% bupivacaine-soaked Surgicel in the gallbladder bed is effective for pain after laparoscopic cholecystectomy.

BACKGROUND: This study aimed to determine the character of pain after laparoscopic cholecystectomy and its relief with 0.5% bupivacaine-soaked Surgicel placed in the gallbladder bed. METHODS: For this study, 60 patients with chronic cholecystitis were divided into four groups of 15 each: group A (bupivacaine-soaked Surgicel kept in gallbladder bed), group B (bupivacaine infiltrated at trocar sites), group C (bupivacaine infiltrated into the gallbladder bed and at trocar sites, and group D (normal saline in the gallbladder bed and at trocar sites). Postoperatively, the character of pain was noted, and its relief was assessed with visual analog scale (VAS) scoring. RESULTS: The findings showed that 78.33% of the patients had visceral pain, 70% experienced parietal, and 23.33% reported shoulder pain after laparoscopic cholecystectomy. The visceral pain was significantly less in the group A patients than in the control subjects (p < 0.05), and none of them experienced shoulder pain. The mean VAS score at 4, 8, and, 24 h in the group A patients also was less than in control group D: 26.37 +/- 16.24 versus 38.30 +/- 9.51, 23.23 +/- 14.28 versus 33.73 +/- 7.96, and 18.36 +/- 13.00 versus 28.60 +/- 9.42, respectively. Trocar-site infiltration alone was not effective in relieving the parietal pain. CONCLUSION: Visceral pain is prominent after laparoscopic cholecystectomy and can be effectively controlled by 0.5% bupivacaine-soaked Surgicel in the gallbladder bed alone. Trocar-site infiltration alone is ineffective.

External duodenal fistula following closure of duodenal perforation.

AIM: Retrospective analysis of experience with management of external duodenal fistula (EDF) without using total parenteral nutrition (TPN). METHOD: Medical records of 31 patients with EDF following closure of duodenal ulcer perforation, treated over a 7-year period (1994-2001), were studied. Twenty-one patients (68%) had evidence of sepsis at presentation or during the course of treatment. None could afford TPN for optimum time. All patients received hospital-based enteral nutrition through nasojejunal tube, besides supportive medical treatment and/or surgery. Peritonitis or failure to insert nasojejunal tube for enteric alimentation led to early surgery. RESULTS: Two patients died of septicemia and multi-organ failure within 48 hours of admission. Fourteen patients (48.3%) initially received conservative treatment (Group I); six of them later required surgery. Fifteen patients (51.7%) underwent early surgery due to peritonitis (n=9) or failure to establish enteral feeding (n=6) (Group II); wound infection, intra-abdominal abscess and septicemia were more common in these patients than those in Group I. Survival rate was higher in Group I than in Group II (86% versus 40%; p< 0.05). Septicemia and gastrectomy were the independent factors associated with high mortality. CONCLUSIONS: EDF can be satisfactorily managed without TPN. Successful placement of enteral feeding line, supportive treatment and delayed surgery can achieve survival in 85% of patients. Minimum intervention is recommended when early surgery is performed in peritonitis or to establish enteral feeding line.

Necrotizing Soft Tissue Infection Caused by Spilled Gallstones.

We report a case of a 57-year-old woman who presented with a necrotizing soft tissue infection of the right anterior abdominal wall, 1 year after open cholecystectomy for gallbladder perforation. Surgical exploration revealed pigmented gallstones along with pus in the abdominal wall and gallbladder fossa. Intraoperative spillage of gallstones is common during both open and laparoscopic cholecystectomy, but, in rare cases, can lead to serious complications including necrotizing infection of the abdominal wall.

Spontaneous closure of stoma.

Intestinal loop stoma is a common surgical procedure performed for various benign and malignant abdominal problems, but it rarely undergoes spontaneous closure, without surgical intervention. Two male patients presented to our emergency surgical department with acute abdominal pain. One of them was diagnosed as having rectosigmoid perforation and underwent diversion sigmoid loop colostomy after primary closure of the perforation. The other was a known case of carcinoma of the rectum who had already undergone low anterior resection with covering loop ileostomy; the patient underwent second loop ileostomy, this time for complicated intestinal obstruction. To our surprise, both the loop colostomy and ileostomy closed spontaneously at 8 weeks and 6 weeks, respectively, without any consequences. Spontaneous stoma closure is a rare and interesting event. The exact etiology for spontaneous closure remains unknown, but it may be hypothesized to result from slow retraction of the stoma, added to the concept of a tendency towards spontaneous closure of enterocutaneous fistula.

FLT PET/CT Is Better Than FDG PET/CT in Differentiating Benign From Malignant Pancreatobiliary Lesions.

PURPOSE: F-fluorothymidine (FLT), unlike FDG, is incorporated exclusively into DNA and is considered a specific marker of cell proliferation. The role of FLT PET/CT scan in differentiating benign from malignant pancreatobiliary tumors is unknown. PATIENTS AND METHODS: Twenty-five suspected pancreatobiliary tumors on contrast-enhanced CT (CECT) scan in 23 patients were evaluated by FDG PET/CT and FLT PET/CT scans. The histopathology or fine-needle aspiration cytology was considered as criterion standard for the diagnosis. Surgeons were blinded to FLT PET/CT results. Management decision was guided by clinical and CECT scan and FDG PET/CT. RESULTS: Five of 23 patients had metastatic disease on CECT imaging. The remaining 18 underwent exploratory laparotomy. Two of them had synchronous lesions. Histopathology/fine-needle aspiration cytology confirmed malignancy in 17 lesions and benign disease in the remaining 8 lesions. All 8 benign lesions were negative on FLT PET/CT. Seven of the 8 benign lesions were clinically diagnosed as malignancy on CECT and FDG PET/CT. The specificity, positive predictive value, and accuracy were higher for FLT PET/CT (100%, 100%, and 92%) compared with CECT (12.5%, 70.83%, and 72%) and FDG PET/CT (12.50%, 69.57%, and 68%). However, the sensitivity of FLT PET/CT (88.24%) was similar to CECT (100%) and FDG PET/CT (94.12%). CONCLUSIONS: Molecular-based FLT PET/CT is a better imaging than FDG PET/CT in differentiating benign from malignant lesions in the pancreatobiliary region. It has a potential to bring down the incidence of preventable radical resection in suspected pancreatobiliary tumors.

Chylothorax after esophagectomy for esophageal cancer: risk factors and management.

BACKGROUND: Chylothorax is an uncommon complication of esophagectomy. It carries significant morbidity and mortality. The predisposing factors are ill-defined. METHODS: We retrospectively evaluated the data of 45 patients of carcinoma esophagus who underwent esophagectomy after neoadjuvant chemoradiotherapy (NACRT) from January 2010 to July 2012 in our tertiary health care center. RESULTS: Four patients (8.88 %) had chylothorax. On analysis of perioperative factors, it was found that patients with chylothorax had tumor in middle third of thoracic esophagus (100 %), shown partial response to neoadjuvant chemoradiation (NACRT) (100 %) and were associated with difficult mediastinal dissection (75 %) leading to higher blood loss requiring transfusion unlike those without chylothorax. There was no significant difference in the incidence of chylothorax following transhiatal, 3/35 = 8.57 % or transthoracic esophagectomy 1/10 = 10 % (p = 0.898). Three patients were managed by transabdominal en masse ligation of tissue between aorta and azygos vein while one patient was managed conservatively. Patients were discharged after a mean hospital stay of 15.5 days. The 30-day mortality rates in the two groups were similar (0 % vs. 4.8 %). CONCLUSION: Difficult mediastinal dissection during esophagectomy in middle esophageal cancer may lead to thoracic duct injury. Complete response to NACRT may reduce the risk of chylothorax. Early transabdominal en masse ligation carries excellent results. Low output fistula following thoracic duct injury can be managed conservatively.

Thrombocytosis and Raised CRP Levels Predicts Advanced Stage in Esophageal Carcinoma.

PURPOSE: The significance of thrombocytosis and raised C-reactive protein (CRP) as prognostic markers in esophageal cancer is unclear. METHODS: We prospectively studied 50 consecutive patients with esophageal cancer and analyzed the relation of preoperative platelet count and CRP levels with the clinico-pathological characteristics and stage of the disease. The platelet count of 319 × 10(9)/L for thrombocytosis and CRP level >6 mg/dl were taken as cut-off values. RESULTS: The incidence of thrombocytosis as well as raised CRP level was 50 %. Eighty percent of patients with thrombocytosis had raised CRP levels. None of patients with early disease (stage I) had thrombocytosis while patients with advanced stage were associated with thrombocytosis, 81.81 % in stage III and 100 % in stage IV (p < 0.001). The incidence of elevated CRP levels has shown progressive linear co-relation with the stage of carcinoma, i.e., 0 % in pathological stage I, 16.67 % in stage II, 45.45 % in stage III, and 100 % in stage IV disease (p = 0.011). Patients with thrombocytosis and patients with raised CRP were associated with pathological nodal metastases in 84.61 % cases (p 0.005) and 61.53 % (p 0.030), respectively. CONCLUSION: Thrombocytosis alone or in combination with raised CRP had progressive linear relation with the stage of esophageal carcinoma.

Pericholecystic adhesions in single v multiple gallstones and their consequences for laparoscopic cholecystectomy.

BACKGROUND: Adhesions are amongst the common reasons for open conversion of laparoscopic cholecystectomy. It is not clear whether this problem is more common with single or multiple gallstones. PATIENTS AND METHODS: The clinical records of 110 patients with chronic cholelithiasis harboring multiple stones in the gallbladder (multiple stone group; MSG) and 45 patients with single stones in the gallbladder (SSG) undergoing laparoscopic cholecystectomy were analyzed for differences in the clinical presentation and outcome with special reference to the incidence of pericholecystic adhesions, size of the stones, and their implications for conversion and complications. RESULTS: Patients in the SSG had a significantly higher incidence of dense pericholecystic adhesions in the region of the porta hepatis (P = 0.003). Eleven patients in the SSG (24.4%) were converted to open cholecystectomy. Dense pericholecystic adhesions around the porta hepatis alone contributed to nine of these conversions (81.8%). The size of the stones was significantly greater (P < 0.001) in those patients of the SSG who required conversion to open cholecystectomy. Thirteen patients of the MSG (11.8%) required conversion to open cholecystectomy. Dense pericholecystic adhesions alone contributed to conversion in four cases (30.7%), and the size of the gallstones was not significantly different (P = 0.981) in patients with or without conversion to open cholecystectomy. There was no difference in the clinical presentation or complications in the two groups of patients. CONCLUSION: Dense adhesions in the porta hepatis are significantly more common in patients with single stones and are the most common reason for open conversion.

Pancreatoduodenectomy in abdominal trauma: a viable alternative.

Pancreatoduodenectomy was performed in five patients with severe pancreatoduodenal trauma following vehicular accidents. Three of them presented within five hours of injury and two patients, four and ten days later. Surgery was performed within 6-12 hours of hospitalization. All patients underwent pancreatoduodenectomy; in one the pancreatic stump was closed completely owing to its friability. Three patients survived; two succumbed to ongoing preoperative septicemia due to late presentation. The results of pancreato-duodenectomy are good when patients are operated on early, before the development of sepsis.

Ectopic pregnancy presenting as lower gastro-intestinal hemorrhage.

A patient with ruptured tubal pregnancy presenting with lower gastrointestinal bleed is described. Colonoscopy and other investigations were not helpful; laparotomy was diagnosis as well as therapeutic.

Hepatopancreatoduodenectomy in advanced carcinoma gall bladder.

A patient with advanced carcinoma of the gall bladder was treated by hepatopancreatoduodenectomy. She had no postoperative complication, and is anicteric six months after surgery despite local recurrence.

Posterior segment duct injury in laparoscopic cholecystectomy.

We report a 34-year-old woman with posterior segment duct injury during laparoscopic cholecystectomy. The diagnosis was made by intra- and postoperative cholangiogram. The injured duct was repaired over a T-tube. The patient recovered uneventfully.

Pseudoaneurysm of external iliac artery secondary to appendicular abscess.

Infective pseudoaneurysm of External iliac artery, a new complication of appendicular abscess is described. It's etiopathogenesis, clinical presentation and management are briefly reviewed.

Biliary mishaps in laparoscopic cholecystectomy.

AIM: To determine the incidence and types of biliary complications following laparoscopic cholecystectomy in our patients. METHODS: The clinical records of one hundred and fifty-five patients undergoing laparoscopic cholecystectomy were reviewed. RESULTS: Five patients developed biliary mishaps. The overall incidence of biliary complications was 3.2% (5/155). The incidence of major complications was 1.9% (3/155) and the incidence of minor biliary complications was 1.2% (2/155). In 3 out of 5 patients the mishap was attributed to developmental anomalies. Dense pericholecystic adhesions and cystic duct blow out were responsible for biliary complications in one patient each. Bilioenteric anastomosis was performed in two patients and restoration of continuity of the common hepatic duct over a T-tube was done in one patient. Side hole in an accessory duct was repaired over a T-tube and cystic duct blow out was managed with endoscopic biliary drainage alone. CONCLUSIONS: A high index of suspicion of developmental anomalies, cautions approach in difficult cases and readiness to consider conversion to open cholecystectomy are recommended to reduce the incidence of biliary complications in laparoscopic cholecystectomy.

Clinical significance of carcinoembryonic antigen in colorectal malignancy.

Carcinoembryonic antigen (CEA) assay was performed in 40 patients of histologically proven colorectal carcinoma. The overall incidence of positivity was 72.5%. The incidence increased from 40% in Duke's A stage to 84.6% in Duke's C stage. Similarly the mean CEa levels also increased as the disease advanced i.e. 4.96 ng/ml, 8.07 ng/ml and 12.7 ng/ml in Duke's A, B and C respectively. Cancer with poor prognosis i.e. poorly differentiated and colloid carcinoma, had significantly less rise in CEA values (P < 0.05) as compared to well differentiated carcinoma. There was no relation of CEA values with the gross appearance of the tumour and lymph node involvement. CEA level came down in all the patients after surgery. Based on the postoperative CEA estimation, complete tumour clearance had been achieved in 86.2% of patients.

Management of duodenal trauma.

The surgical management of fifteen cases of duodenal trauma is reported. Blunt injury of the abdomen was the commonest mode of injury. Thirteen patients (86.6%) had associated intra-abdominal and/or extra-abdominal injuries. Diagnosis of duodenal injury was made at laparotomy in all patients. In the majority of patients (n = 11), either duodenal repair, or anastomosis with the pylorus or jejunum was done. Duodenal diverticulization or pancreaticoduodenectomy were undertaken in 2 patients each. Feeding jejunostomy was an important adjunct for nutritional support. Septicemia with multisystem organ failure and duodenal fistula were lethal complications. Mortality in the present series was 46.6%.
