Simplified Technique of Conventional Cholecystectomy in a Patient with Situs Inversus Totalis: A Case Report from Nepal

Introduction: Situs inversus is a rare autosomal recessive disorder occurring in 1:5,000 to 1:20,000 indiviuals. Cholecystectomy is a standard treatment for symptomatic gallbladder stone. We report a case of cholelithiasis in patient with inversus totalis who underwent cholecystectomy. Case presentation: A 48 years old obese female patient with dextrocardia and hypertention presented with a recurrent left upper abdominal pain for two years. Ultrasound abdomen showed gallbladder stone. Conventional cholecystectomy was done with a small left subcostal incision. The postoperative period was uneventful and the patient was discharged on 3rd post operative day. Conclusion: Cholecystectomy is the treatment of choice in patients with a left sided gallbladder stone, like in normal gallbladder and it is safe.

The Double Gut Point: A Novel Sonographic Sign of Pneumoperitoneum

Pneumoperitoneum is a life-threatening condition, caused by hollow organ perforation. The diagnosis is often difficult, and Point-of-care ultrasound can be useful to distinguish from different conditions, and early set the indication of urgent surgery. We report a critically ill patient presented to the Emergency Department with sudden increase in upper abdominal pain and distension with a diagnosis of small bowel obstruction on ultrasound using a curvilinear probe. After repeating the ultrasound using a linear probe, two dynamic points at mesogastrium very similar to the “double lung point” seen in thoracic ultrasound was detected. This “double gut point” due to bowel ischemia and perforation was confirmed on a computed tomography scan. In this case, the finding of an abdominal “double gut point” allowed us to diagnose pneumoperitoneum, being a novel sign not previously described, that could aid to diagnose small amounts of free air in the peritoneal cavity.

Spontaneous intramural duodenal hematoma in a young woman

Summary: Non-traumatic spontaneous intramural duodenal hematoma is a rare cause of proximal gastrointestinal obstruction which may present with hemorrhage, jaundice and pancreatitis. In this case report we present a case of spontaneous duodenal hematoma in a 28-year-old female with a history of acute pancreatitis, admitted to hospital for convulsive upper abdominal pain with vomiting as suspected pancreatitis. An MRI examination of the abdomen confi rmed intraluminal bleeding into the duodenum. Following supportive therapy the clinical symptoms spontaneously subsided and laboratory parameters improved. Due to early dia gnosis and therapy the patient had a good outcome, without requiring surgery. Repeated imaging showed hematoma resorption. Key words: abdominal pain – vomitus – duodenal hematoma – hemorrhage

Effect of Electrical Impedance Tomography-Guided Early Mobilization in Patients After Major Upper Abdominal Surgery: Protocol for a Prospective Cohort Study

Background: Pulmonary complications are common in patients after upper abdominal surgery, resulting in poor clinical outcomes and increased costs of hospitalization. Enhanced Recovery After Surgery Guidelines strongly recommend early mobilization post-operatively; however, the quality of the evidence is poor, and indicators for quantifying the effectiveness of early mobilization are lacking. This study will evaluate the effectiveness of early mobilization in patients undergoing an upper abdominal surgery using electrical impedance tomography (EIT). Specifically, we will use EIT to assess and compare the lung ventilation distribution among various regions of interest (ROI) before and after mobilization in this patient population. Additionally, we will assess the temporal differences in the distribution of ventilation in various ROI during mobilization in an effort to develop personalized activity programs for this patient population.Methods: In this prospective, single-center cohort study, we aim to recruit 50 patients after upper abdominal surgery between July 1, 2021 and June 30, 2022. This study will use EIT to quantify the ventilation distribution among different ROI. On post-operative day 1, the nurses will assist the patient to sit on the chair beside the bed. Patient's heart rate, blood pressure, oxygen saturation, respiratory rate, and ROI 1-4 will be recorded before the mobilization as baseline. These data will be recorded again at 15, 30, 60, 90, and 120 min after mobilization, and the changes in vital signs and ROI 1-4 values at each time point before and after mobilization will be compared.Ethics and Dissemination: The study protocol has been approved by the Institutional Review Board of Liaocheng Cardiac Hospital (2020036). The trial is registered at chictr.org.cn with identifier ChiCTR2100042877, registered on January 31, 2021. The results of the study will be presented at relevant national and international conferences and submitted to international peer-reviewed journals. There are no plans to communicate results specifically to participants. Important protocol modifications, such as changes to eligibility criteria, outcomes, or analyses, will be communicated to all relevant parties (including investigators, Institutional Review Board, trial participants, trial registries, journals, and regulators) as needed via email or in-person communication.

Unraveling Variations in Celiac Trunk and Hepatic Artery by CT Angiography to Aid in Surgeries of Upper Abdominal Region

Understanding of variations in the course and source of abdominal arteries is crucial for any surgical intervention in the peritoneal space. Intricate surgeries of the upper abdominal region, such as hepato-biliary, pancreatic, gastric and splenic surgeries, require precise knowledge of regular anatomy and different variations related to celiac trunk and hepatic artery. In addition, information about the origin of inferior phrenic artery is important in conditions such as hepatocellular carcinoma and gastroesophageal bleeding management. The present study gives an account of anatomical variations in origin and branching pattern of celiac trunk and hepatic artery by the use of CT (computed tomographic) angiography. The study was performed on 110 (66 females and 44 males) patients in a north Indian population. Results unraveled the most common celiac trunk variation as hepatosplenic trunk with left gastric artery, which was observed in 60% of cases, more common in females than in males. Gastrosplenic and hepato-gastric trunk could be seen in 4.55% and 1.82% cases respectively. Gastrosplenic trunk was more commonly found in females, whereas hepato-gastric trunk was more common in males. A gastrosplenic trunk, along with the hepato-mesenteric trunk, was observed in 1.82% cases and was more common in males. A celiacomesenteric trunk, in which the celiac trunk and superior mesenteric artery originated as a common trunk from the aorta, was seen only in 0.91% of cases, and exhibited an origin of right and left inferior phrenic artery from the left gastric artery. The most common variation of hepatic artery, in which the right hepatic artery was replaced and originated from the superior mesenteric artery, was observed in 3.64%, cases with a more common occurrence in males. In 1.82% cases, the left hepatic artery was replaced and originated from the left gastric artery, which was observed only in females. Common hepatic artery originated from the superior mesenteric artery, as observed in 1.82% cases, with slightly higher occurrence in males. These findings not only add to the existing knowledge apart from giving an overview of variations in north Indian population, but also give an account of their correlation with gender. The present study will prove to be important for various surgeries of the upper abdominal region.

Electrical Impedance Tomography Predicts Weaning Success in Adult Patients With Delayed Upper Abdominal Surgery: A Single-Center Retrospective Study

Objective: To evaluate the predictive value of electrical impedance tomography (EIT) in patients with delayed ventilator withdrawal after upper abdominal surgery.Methods: We retrospectively analyzed data of patients who were ventilated >24 h after upper abdominal surgery between January 2018 and August 2019. The patients were divided into successful (group S) and failed (group F) weaning groups. EIT recordings were obtained at 0, 5, 15, and 30 min of spontaneous breathing trials (SBTs) with SBT at 0 min set as baseline. We assessed the change in delta end-expiratory lung impedance and tidal volume ratio (ΔEELI/VT) from baseline, the change in compliance change percentage variation (|Δ(CW-CL)|) from baseline, the standard deviation of regional ventilation delay index (RVDSD), and global inhomogeneity (GI) using generalized estimation equation analyses. Receiver operating characteristic curve analyses were performed to evaluate the predictive value of parameters indicating weaning success.Results: Among the 32 included patients, ventilation weaning was successful in 23 patients but failed in nine. Generalized estimation equation analysis showed that compared with group F, the ΔEELI/VT was lower, and the GI, RVDSD, and (|Δ(CW-CL)|) were higher in group S. For predicting withdrawal failure, the areas under the curve of the ΔEELI/VT, (|Δ(CW-CL)|), and the RVDSD were 0.819, 0.918, and 0.918, and 0.816, 0.884, and 0.918 at 15 and 30 min during the SBTs, respectively.Conclusion: The electrical impedance tomography may predict the success rate of ventilator weaning in patients with delayed ventilator withdrawal after upper abdominal surgery.

Do ARISCAT scores help to predict the incidence of postoperative pulmonary complications in elderly patients after upper abdominal surgery? An observational study at a single university hospital

Background The incidence of postoperative pulmonary complications (PPCs) is increasing in line with the rise in the number of surgical procedures performed on geriatric patients. In this study, we determined the incidence and risk factors of PPCs in elderly Thai patients who underwent upper abdominal procedures, and we investigated whether the Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score helps to predict PPCs in Thais. Methods A retrospective study was conducted on upper abdominal surgical patients aged over 65 years who had been admitted to the surgical ward of Siriraj Hospital, Mahidol University, Thailand, between January 2016 and December 2019. Data were collected on significant PPCs using the European Perioperative Clinical Outcome definitions. To identify risk factors, evaluations were made of the relationships between the PPCs and various preoperative, intraoperative, and postoperative factors, including ARISCAT scores. Results In all, 1100 elderly postoperative patients were analyzed. Their mean age was 73.6 years, and 48.5% were male. Nearly half of their operations were laparoscopic cholecystectomies. The incidence of PPCs was 7.7%, with the most common being pleural effusion, atelectasis, and pneumonia. The factors associated with PPCs were preoperative oxygen saturation less than 96% (OR = 2.6, 1.2–5.5), albumin level below 3.5 g/dL (OR = 1.7, 1.0–2.8), duration of surgery exceeding 3 h (OR = 2.0, 1.0–4.2), and emergency surgery (OR = 2.8, 1.4–5.8). There was a relationship between ARISCAT score and PPC incidence, with a correlation coefficient of 0.226 (P < 0.001). The area under the curve was 0.72 (95% CI, 0.665–0.774; P < 0.001). Conclusions PPCs are common in elderly patients. They are associated with increased levels of postoperative morbidities and extended ICU and hospital stays. Using the ARISCAT score as an assessment tool facilitates the classification of Thai patients into PPC risk groups. The ARISCAT scoring system might be able to be similarly applied in other Southeast Asian countries.
