Splenectomy for Visceral Leishmaniasis Out of an Endemic Region: A Case Report and Literature Review.

Visceral leishmaniasis (also known as kala-azar) is characterized by fever, weight loss, swelling of the spleen and liver, and pancytopenia. If it is not treated, the fatality rate in developing countries can be as high as 100% within 2 years. In a high risk situation for perioperative bleeding due to severe thrombocytopenia/coagulopathy, we present a rare challenge for urgent splenectomy in a patient with previously undiagnosed visceral leishmaniasis. A histologic examination of the spleen revealed a visceral leishmaniasis, and the patient was successfully treated with amphotericin B.

Impact of prolonged liver ischemia during intermittent Pringle maneuver on postoperative outcomes following liver resection.

BACKGROUND: The aim of this study was to compare postoperative outcomes following liver resection between patients with prolonged cumulative ischemia time (CIT) which exceeded 60 min and patients with CIT less than 60 min. METHODS: Between March 2020 and October 2022, 164 consecutive patients underwent liver resection at the Unit for hepato-bilio-pancreatic surgery, University Clinic for Digestive Surgery in Belgrade, Serbia. Intermittent Pringle maneuver was routinely applied. Depending on CIT during transection, patients were divided into two groups: group 1 (CIT <60 min) included 101 patients, and group 2 (CIT ≥60 min) included 63 patients. RESULTS: Median operative time (210 vs. 400 min) and CIT (30 vs. 76 min) were longer in the Group 2 (p < 0.001). Intraoperative blood loss was higher in the Group 2 (150 vs 500 ml), p < 0.001. The perioperative transfusion rate was similar between the groups (p = 0.107). There was no difference in postoperative overall morbidity (50.5% vs. 58.7%, p = 0.337) and major morbidity (18.8 vs. 19%, p = 0.401). In-hospital mortality, 30-day mortality, and 90-day mortality were similar between the groups (p = 0.408; p = 0.408; p = 0.252, respectively). Non-anatomical liver resection was the only predictive factor of 90-day mortality identified by multivariate analysis (p = 0.047; Relative Risk = 0.179; 95% Confidence Interval 0.033-0.981). CONCLUSION: Intermittent Pringle maneuver with CIT exceeding 60 min is a safe method for bleeding control during liver resection with no impact on postoperative morbidity and mortality.

"Bezoar Egg"-A Rare Cause of Small Bowel Obstruction.

Small bowel obstruction is a frequent medical condition with various causes, the most common being postoperative adhesions, volvulus, intussusception, hernias, and tumors. A bezoar-induced blockage of the small intestine is a rare condition that accounts for approximately 4% of all small bowel obstruction cases. Herein, we present the case report of a 71-year-old patient with diffuse abdominal pain caused by a small bowel obstruction due to a calcified bezoar (bezoar egg) resulting from a post-radiation intestinal stricture. The patient underwent a small bowel excision with the extraction of the bezoar, after which a full recovery was made.

Is there any benefit from expanding the criteria for the resection of hepatocellular carcinoma in cirrhotic liver? Experience from a developing country.

BACKGROUND: Patients with large-size (>10 cm) hepatocellular carcinoma (HCC) in Child B cirrhosis are usually excluded from curative treatment, i.e., hepatic resection, because of marginal liver function and poor outcome. This study was designed to evaluate the feasibility of the radiofrequency (RF)-assisted sequential "coagulate-cut liver resection technique" in expanding the criteria for resection of large HCC in cirrhotic livers with impaired liver function. METHODS: Forty patients with Child-Pugh A or B cirrhosis underwent liver resection from December 1, 2001 to December 31, 2008. Of these, 20 patients (13 Child-Pugh A and 7 Child-Pugh B) with advanced stage HCC (stage B and C according to Barcelona-Clinic Liver Cancer Group) underwent major liver resection. The two groups were comparable in terms of patient age, liver cirrhosis etiology, tumor number, and size. RESULTS: All resections were performed without the Pringle maneuver. There was no significant difference found between the two groups regarding resection time, perioperative transfusion, postoperative complications, hospital stay, and day 7 values of hemoglobin and liver enzymes. Likewise, there was no significant difference found in the overall survival between Child A and Child B patients who underwent major liver resection CONCLUSIONS: RF-assisted sequentional "coagulate-cut liver resection technique" may be a viable alternative for management of patients with advanced HCC in cirrhotic liver with impaired function.

Actinomycotic hepatic abscess in woman with longstanding intrauterine contraceptive device.

We present a case of a 50 year-old female bearing an intrauterine contraceptive device for 20 years who was diagnosed with abdominopelvic actinomycosis with liver dissemination. The patient was successfully treated by a combination of surgical resection and a 3-month course of amoxicillin.

Hepatocellular carcinoma: From clinical practice to evidence-based treatment protocols.

Hepatocellular carcinoma (HCC) is one of the major malignant diseases in many healthcare systems. The growing number of new cases diagnosed each year is nearly equal to the number of deaths from this cancer. Worldwide, HCC is a leading cause of cancer-related deaths, as it is the fifth most common cancer and the third most important cause of cancer related death in men. Among various risk factors the two are prevailing: viral hepatitis, namely chronic hepatitis C virus is a well-established risk factor contributing to the rising incidence of HCC. The epidemic of obesity and the metabolic syndrome, not only in the United States but also in Asia, tend to become the leading cause of the long-term rise in the HCC incidence. Today, the diagnosis of HCC is established within the national surveillance programs in developed countries while the diagnosis of symptomatic, advanced stage disease still remains the characteristic of underdeveloped countries. Although many different staging systems have been developed and evaluated the Barcelona-Clinic Liver Cancer staging system has emerged as the most useful to guide HCC treatment. Treatment allocation should be decided by a multidisciplinary board involving hepatologists, pathologists, radiologists, liver surgeons and oncologists guided by personalized -based medicine. This approach is important not only to balance between different oncologic treatments strategies but also due to the complexity of the disease (chronic liver disease and the cancer) and due to the large number of potentially efficient therapies. Careful patient selection and a tailored treatment modality for every patient, either potentially curative (surgical treatment and tumor ablation) or palliative (transarterial therapy, radioembolization and medical treatment, i.e., sorafenib) is mandatory to achieve the best treatment outcome.

The effects of early rehabilitation in patients with surgically treated colorectal cancer.

Colorectal cancer is one of the most common cancer. Caught early, it is often curable. The important role in functional recovery of these patients, have enhanced recovery after surgery (ERAS) clinical care protocol and early rehabilitation. The goal of this research is the objective evaluation of the effects of early rehabilitation in patients after surgical treatment of colorectal cancer, respecting their functional recovery and quality of life, before and after rehabilitation. Tis study was made as experimental, randomized, controlled clinical trial, opened type.The examination included 58 patients (39 males and 19 females), age from 36 to 85 years, average 63.3, with surgically treated colorectal cancer. All patients had appropriate early multimodal accelerated rehabilitation program.The mean value of this program was 7,24 days. As observing parameter was used short form, 36 items health related questionnaire (SF-36), with two summary measures-Physical component summary (PCS) and Mental component summary (MCS), for the evaluation of quality of life, before and after treatment. For the statistical analysis of the aquired data, before and after therapy, was used Student's t-test. Afer therapy, the quality of life of patients was significantly improved, physical health (p< 0.01), as well as mental health (p<0,01). SF36 score after rehabilitation, show important improvement of quality of life in early treated patients. These results show exellent therapeutic possibilities of enhaced recovery clinical care protocol and early rehabilitation procedures. Acording to the results of this study, it can be concluded that early rehabilitation accelerated program is very effective in treatment of patients with surgically treated colorectal cancer.

Heparin-induced thrombocytopenia with iliacofemoropopliteal thrombosis in a patient operated for colorectal carcinoma liver metastases.

We report a case of heparin-induced thrombocytopenia thrombosis (HITT) syndrome in a patient prophylactically treated with low molecular weight heparin. A 66-year-old men underwent radiofrequency-assisted partial liver resection for colorectal carcinoma liver metastases a year-and-a-half after he had been operated for rectal cancer. In the postoperative period, patient was prophilactically treated with reviparin sodium. On the 8th postoperative day, the platelet count decreased by more than 50% without clinical signs of thrombosis. HITT syndrome was suspected on the 19th postoperative day, after iliacofemoropopliteal thrombosis had developed, and related diagnosis was supported by the strongly positive particle gel agglutination technique immunoassay. Heparin was withdrawn and alternative anticoagulant, danaparoid sodium, was introduced in therapeutic doses. Despite delayed recognition, favorable clinical outcome was achieved. HITT syndrome should be considered with priority among the possible causes of thrombocytopenia in a surgical patient on heparin.

A radiofrequency-assisted minimal blood loss liver parenchyma dissection technique.

BACKGROUND/AIMS: Intraoperative blood loss is still a major concern for surgeons operating on the liver since it is associated with a significantly higher rate of postoperative complications and shorter long-term survival. An original radiofrequency (RF)-assisted minimal blood loss technique for transecting liver parenchyma is presented. METHODS: In a prospective study, starting November 2001 and ending December 2005, a total of 90 RF-assisted liver resections were done. Pre-cut coagulative desiccation was produced by the Cool-tip (Valleylab, Tyco) water-cooled, single, RF tumor ablation electrode connected to a 480-kHz 200 W generator (Valleylab Cool-tip RF System). Vascular occlusion techniques and low central venous pressure anesthesia were not used. RESULTS: Only 14 (15.5%) patients received blood transfusion (mean transfused blood volume 397 ml; mode 310 ml) and 10 of 14 patients received <310 ml of blood. There was no statistical difference between the patients who underwent major and minor liver resection in frequency of blood transfusion. Blood loss was associated with dense adhesions and difficult liver mobilization and not with liver transection. CONCLUSION: The 'sequential coagulate-cut' RF-assisted liver resection technique is a safe liver transection technique associated with minimal blood loss and it has facilitated tissue-sparing liver resection.

Surgery for colorectal liver metastases: expanding the boundaries but where have all the patients gone.

AIM: To review and discuss the current strategies and controversies in the surgical management of colorectal cancer liver metastases. METHODS: An analysis of indications, contraindications and scoring systems and concepts for expanding the indications for resection are discussed. The findings and discussion are related to our own experience, especially with radiofrequency assisted liver resection for colorectal cancer liver metastases. RESULTS: Resection is the only management strategy that can potentially cure the patient. Certain controversies still exist, such as contraindications for surgery, timing of treatment of synchronous metastases, significance of extra-hepatic disease etc. Strategies that can improve respectability are discussed. Parenchyma oriented, tissue sparing surgery facilitates reresection should it become necessary. CONCLUSION: The management of colorectal cancer liver metastases is still a confusing issue for general oncologists and general surgeons. A multidisciplinary approach that tailors the management strategy to the individual patient is the only option that provides optimal results for patients with advanced disease.
