Modified hepaticocholecystoenterostomy technique for certain hepatobiliary and pancreatic diseases: Case series report by a single surgeon.

Prior to this research, very few reports of hepaticocholecystoenterostomy (HCE) and its modification have been published. Two anastomoses were used to establish a biliary bypass using the gallbladder as a conduit by a senior hepato-biliary surgeon. Between 2013 and 2019, 11 patients (five men and six women) with a mean age of 61.7±15.7 (range, 31-85) years were seen. Disease indications included periampullary malignant tumours of Vater (7 cases), chronic pancreatitis (1 patient), cystic pancreatic head tumours (2 patients), and choledochal cysts (1 patient). Pancreaticoduodenectomy, bypass, cholangiocarcinoma, and choledochal cystectomy were performed on 4, 4, 2, and 1 patients, respectively. Follow-up showed no jaundice at all with no recurrent biliary obstruction. HCE is both safe and effective in a subgroup of patients. This is a treatment of choice in some instances, such as a small common bile duct, a limited surgical field in the hilar area, or a difficult hepaticojejunostomy.

Laparoscopic cholecystectomy for the treatment of acute cholecystitis in a Vietnamese male patient with ankylosing spondylitis combined with chronic obstructive pulmonary disease: A rare case report.

INTRODUCTION: Ankylosing spondylitis (AS) presents with difficulty in intubation, restricted ventilatory abnormalities, and frequent cardiac involvement. However, with improvements in anaesthesiology and surgical expertise, laparoscopic cholecystectomy can be extended to individuals with kyphoscoliosis caused by AS. CASE PRESENTATION: We report the case of a 68-year-old man who had severe AS for more than 30 years following necrosis acute cholecystitis. Signs of severe AS included the patient's inability to lie down and difficulty in breathing. We utilised four trocars but changed the placement positions and used suction tubes during laparoscopic cholecystectomy. The patient was discharged from the hospital after 14 days. DISCUSSION: Severe AS is not a contraindication to laparoscopic surgery. However, patients with AS or kyphosis must be carefully assessed for respiratory dysfunction, cardiac impairment, difficult airway, and other special conditions. Anaesthesiologists and surgeons should collaborate with surgical decisions in patients with severe respiratory limitations. CONCLUSION: Laparoscopic cholecystectomy can be performed effectively in patients with severe AS. With the use of a laparoscopic hook and suction equipment, it is possible to easily dissect the Calot triangle during acute cholecystitis.

Trans-Lycopene and ß-Cryptoxanthin Intake and Stomach Cancer in Vietnamese Men: A Pilot Case-Control Study.

OBJECTIVE: To examine the association between dietary intake of Trans-Lycopene and ß-Cryptoxanthin and stomach cancer in Vietnamese men. METHODS: A case-control study including 80 male incident stomach cancer cases and 146 male controls was performed in a general hospital in Viet Nam. A validated semi-quantitative food frequency (SQFFQ) and demographic lifestyle questionnaire were designed, and venous blood samples were collected to determine H. pylori status by IgG ELISA. Nutrient intake was converted using the data of SQFFQ and the Nutritive Composition Table of Vietnamese Foods, updated in 2019. The respective associations between Trans-Lycopene and ß-Cryptoxanthin intake and stomach cancer were examined using unconditional logistic regression analysis with adjustments for possible cofactors. RESULTS: Both Trans-Lycopene and ß-Cryptoxanthin intake and stomach cancer showed a significantly inverse association, tertile-3 versus tertile-1, (OR = 0.15, 95%CI: 0.06-0.35, p trend = 0.00) and (OR = 0.34, 95%CI: 0.14-0.79, p trend = 0.02, respectively). For Trans-Lycopene intake stratifying by H. pylori status remained the benefit effect against stomach cancer among H. pylori-negative participants (OR = 0.15, 95%CI: 0.03-0.69, p trend = 0.02) and H. pylori-positive participants (OR = 0.13, 95%CI: 0.04-0.42, p trend = 0.00). CONCLUSIONS: Both Trans-Lycopene and ß-Cryptoxanthin intake showed a strong protective effect against stomach cancer. The findings suggest that these two types of fat-soluble micronutrients would be considered as an anti-cancer therapy for both primary and secondary prevention.

A ruptured pancreatic pseudocyst causes acute peritonitis with clinical characteristics of a gastrointestinal tract perforation.

Intraperitoneal air in pancreatic pseudocysts is a rare complication that can jeopardize hemodynamic stability and requires emergency surgery. A 61-year-old man was admitted to our hospital after abdominal pain, vomiting and diarrhea. Computed tomography showed a hollow visceral perforation with intraperitoneal air and two pseudocysts close to the pancreas. The patient was transferred to the emergency operating room with symptoms of septic shock. We histopathologically diagnosed a ruptured pancreatic pseudocyst combined with an intracystic haemorrhage. We resected a portion of the pseudocyst wall using surface electrocautery inside the lumen, cholecystectomy and peritoneal toilet and maintained adequate external drainage. The patient was discharged on postoperative Day 12. The patient achieved relapse-free survival for 12 months postoperatively. Ruptured pancreatic pseudocysts with extraluminal gas are dangerous if effective medical interventions are not performed. Emergency surgery should be completed as soon as possible to drain the pancreatic cyst and cleanse the abdomen.

Interaction of Helicobacter pylori Infection with Waterpipe Tobacco Smoking in the Development of Stomach Cancer in Vietnamese Men.

OBJECTIVE: This study aims to examine the joint effect of H. pylori infection and tobacco smoking on the development of stomach cancer among Vietnamese men. METHODS: A total of 80 stomach cancer cases and 146 controls were recruited in a case-control study conducted in a general hospital. Information on sociodemographic, anthropometric characteristics, tobacco smoking, and the dietary pattern was obtained based on a semi-quantitative food frequency and demographic lifestyle questionnaire; and venous anti-H. pylori IgG antibodies were tested by ELISA. Unconditional logistic regression analysis with adjustment for potential confounding was performed to estimate the association between target exposures and stomach cancer. RESULTS: An increase in antibody level was related to an elevated odds of stomach cancer (Fifth versus bottom quintile, OR=3.07; 95%CI: 1.16, 8.12; p for trend = 0.032). Compared to participants who were negative with both H. pylori infection and tobacco smoking (either cigarette or waterpipe tobacco), individuals exposed to both these factors showed significantly greater odds of stomach cancer (OR=3.58. (95%CI: 1.32, 9.76, p=0.013). A similar combined impact of H. pylori infection and tobacco smoking was found in individuals who smoked a cigarette (excluded exclusive waterpipe tobacco smokers, ORs = 3.17; 95%CI: 1.13, 8.94, p=0.029) or waterpipe tobacco (excluded exclusive cigarette smokers; OR= 3.96, 95%CI: 1.28, 12.26, p=0.017). CONCLUSIONS: The present study suggests an interaction between H. pylori infection and tobacco smoking, even waterpipe tobacco, to induce stomach cancer.

Waterpipe Tobacco Smoking and Risk of Stomach Cancer: A Case-Control Study in Vietnamese Men.

OBJECTIVE: This study investigated the impacts of waterpipe tobacco (WTP) and cigarette smoking on stomach cancer development in Vietnamese men. METHODS: A total of 80 stomach cancer cases and 146 controls were recruited in a hospital-based case-control study. Data on sociodemographic, anthropometric characteristics, tobacco smoking, and the dietary pattern was obtained based on a semi-quantitative food frequency and demographic lifestyle questionnaire; and venous anti-Helicobacter pylori IgG antibodies were tested by ELISA. Unconditional logistic regression analysis with adjustments for potential confounding was performed to estimate the association between target exposures and stomach cancer. RESULTS: Compared to the never tobacco smokers, the risk of stomach cancer significantly increased among tobacco smokers (OR 2.95, 95%CI 1.26-6.90, p=0.013). Those who early started tobacco smoking before 26 years old had a high risk of SC (OR 3.04, 95%CI 1.29-7.20, p for trend=0.011). For types of tobacco, It was increased risk in exclusively cigarette smokers (OR 2.85, 95%CI 1.19-6.85, p=0.019) and in WPT smokers (OR 3.09, 95%CI 1.24-7.68, p=0.015). The daily frequency and longer duration of exclusively WPT or cigarette smoking tended to be significantly higher SC risk. CONCLUSIONS: The findings suggest that tobacco smoking, particularly water pipe tobacco smoking, dramatically and independently increased the risk of stomach cancer.

Laparoscopic Surgery for Intestinal Obstruction Caused by an Internal Paracecal Hernia.

Paracecal hernia is rarely associated with ischemia and has seldom been reported in the few published studies in the review literature. We present a case of incarcerated paracecal hernia with intestinal obstruction that was effectively treated with laparoscopic intervention. A 64-year-old woman who had not previously undergone any intestinal surgery arrived complaining of abdominal pain and vomiting at our hospital. Abdominal computed tomography suggested intestinal obstruction. A laparoscopic emergency procedure demonstrated an incarcerated small bowel loop in the paracecal region. The confined small bowel was removed from the paracecal area. On the fourth postoperative day, the patient was discharged. This case is unusual because the patient presented with small bowel strangulation, leading to intestinal obstruction. Laparoscopic surgery is beneficial for diagnosing internal hernias and curing small-bowel obstructions caused by paracecal hernias.

Long- and short-term survival following laparoscopic and open pancreaticoduodenectomy for patients with periampullary tumors in Vietnam.

BACKGROUND: Laparoscopic pancreaticoduodenectomy (LPD) is a less invasive alternative to the traditional open pancreaticoduodenectomy (OPD) approach used to treat periampullary tumors. However, previous studies examining the advantages of this surgery over OPD have produced mixed results. Here, a retrospective observational approach was used to compare the short- and long-term outcomes of patients with periampullary tumors who underwent LPD or OPD at a single institution in Vietnam. MATERIALS AND METHODS: Data were obtained from hospital medical records collected over five years from patients that underwent OPD or LPD. Information on demographics, medical status, tumor characteristics, operative variables, complications, and mortality was examined. Survival curves were constructed and the stepwise multivariate Cox proportional hazard model was used to identify the factors associated with the risk of death following surgery. RESULTS: Eighty-four patients aged 26-80 years were included. Twenty-two patients underwent LPD and 62 received OPD. The operative time for the LPD group was significantly longer than that for the OPD group, and the LPD group was less likely to require a blood transfusion during surgery. While the short- and long-term survival rates did not differ for the procedures, the factors associated with the risk of death following surgery were tumors at the N1 stage and an age >65 years. CONCLUSION: Both LPD and OPD procedures for treating periampullary tumors exhibited comparable safety profiles, with similar short-term outcomes and long-term survival rates observed. Future studies with a larger sample size should be conducted to further examine the treatment outcomes following these surgical approaches.

Efficacy of laparoscopic-assisted pancreaticoduodenectomy in Vietnamese patients with periampullary of Vater malignancies: A single-institution prospective study.

INTRODUCTION: Minimally invasive pancreaticoduodenectomy is a technically complex technique, that is being used to treat periampullary malignancy. We provide our experience with laparoscopic-assisted pancreaticoduodenectomy (LAPD) with statistics on the outcomes of periampullary cancer patients. MATERIAL AND METHOD: Thirty patients underwent surgery between June 1, 2016 and May 30, 2020, with 21 undergoing classical PD and 9 undergoing pylorus-preserving pancreaticoduodenectomy (PPPD). Prospectively gathered data on surgical outcomes and long-term oncological results are given. RESULTS: The median operative time was 277.5 min (range, 258.7-330 min), and the median intraoperative estimated blood loss was 319.5 mL (range, 241.2-425 mL). The rate of conversion to OPD, surgical reintervention, and mortality was 20%, 13.3%, and 10% respectively. Cumulative surgery-related morbidity was 33.4%, including bleeding (n = 4), severe POPF (n = 4), biliary fistula (n = 1), DGE (n = 2), and intestinal obstruction (n = 1). Pathologic diagnoses were AoV cancer (n = 23), distal CBD cancer (n = 4), PDAC (n = 2), and AoV NET (n = 1). The mean survival time of the LAPD group was 29.9 months. The long-term survival time of the N0 group was 36.8 months, which was significantly longer than that of the N1 group. The long-term survival times of stages I-B, II-A, and II-B were 36.9, 26.5, and 15.7 months, respectively (p = 0.016). CONCLUSION: LAPD has a high rate of conversion to OPD, morbidity, and mortality. However, LPD is feasible technique for highly selected patients. Lymph node metastasis and stage of disease are the risk factors for long-term survival.

Pancreaticoduodenectomy for hepatic portal lymph node metastasis after hepatic resection for hepatocellular carcinoma: A clinical case report.

INTRODUCTION: In 2018, Hepatocellular carcinoma (HCC) was predicted to be the sixth most commonly diagnosed cancer. Extra-hepatic metastasis due to HCC is a poor prognostic factor, depending on the stage of the disease. PRESENTATION OF CASE: We report a case of a 52-years old male who had undergone Segment 5 (S5) hepatectomy for HCC of 4.7 × 2 cm. Transcatheter arterial chemoembolization (TACE) four times postoperatively was performed based on a preoperative diagnosis of a recurrent tumour at the S1. After 2 years, the solitary tumour (7.5 × 2.5 × 3.5 cm) is located behind the right lobe of the liver and the head of the pancreas. The tumour was abnormally supplied with blood from the superior mesenteric artery (SMA) and the gastroduodenal artery (GDA). The patient was underwent pancreaticoduodenectomy (PD) to remove a large tumour. Postoperative pathology and immunohistochemical staining showed metastatic HCC. There was no tumour recurrence after 6 months. DISCUSSION: The organs in the body that liver cancer cells most often spread to are the lungs (44%), the portal vein (35%), the hepatobiliary ganglion (27%), and a small number of cases of bone, eye socket, bronchus metastases. Otherwise, recurrence of lymph nodes (LNs) after hepatectomy for HCC is very rare. CONCLUSIONS: HCC can metastasize to the hepatic pedicle LN after hepatectomy and maybe confused with recurrent liver tumours in the S1. Indications for PD are feasible for solitary metastatic at peri-pancreas. Pathology incorporating immunohistochemistry can determine the origin of metastases.

Outcomes of surgical management of peptic ulcer perforation using the falciform ligament: A cross-sectional study at a single centre in Vietnam.

INTRODUCTION: Peptic ulcer perforation (PUP) is one of the most common critical surgical emergencies. The omentum flap is commonly used to cover a PUP. However, the omentum cannot be used in cases of severe peritonitis or previous surgical removal. This is the first study conducted in Vietnam that was designed to analyse the outcomes of patients with PUPs who were treated using the falciform ligament. METHOD: In this study, we retrospectively identified 40 consecutive patients who were treated for PUP at a single high-volume centre in Vietnam from February 2018 to February 2021. Peptic ulcer perforation was measured during diagnostic evaluation based on preoperative imaging, such as X-ray, and CT scan. Patients who had malignancy, laparoscopic surgery, omentopexy and nonoperative treatment were excluded from this research. RESULTS: Forty patients were included; the mean age of the patients was 66.3 years (range 33-99 years), and some patients had comorbid disease (57.5%), hypertension (30%), diabetes (10%), cirrhosis (7.5%), and chronic renal failure (7.5%). The PUPs were located in the duodenum (80%), or the pyloric (15%) and prepyloric (5%) regions. The procedures used to treat the patients included duodenostomy (32.5%), gastrojejunostomy (37.5%), and antrum resection (2.5%). The average operative time was 88.6 min (45-180 min), hospital stay was 9.6 days (2-35 days), and oral intake was started at 4.1 days (3-8 days); additionally, the 30-day mortality (17.5%) and incidences of pneumonia (25%), multiorgan failure (15%), acute liver failure (5%), wound infection (7.5%), and ulcer peptic fistula (0%) were assessed. Univariate tests showed that an ASA ≥ III and comorbidities, such as pulmonary complications, liver failure and multiorgan failure, were associated with mortality. The multivariate test showed that multiorgan failure was the only factor related to mortality. CONCLUSION: The falciform ligament can be efficiently used for the closure of a PUP. Although there were no instances of complication with a reperforated peptic ulcer, the mortality rate was slightly highly related to severe comorbidities and postoperative multiorgan failure.

H. pylori Infection and Colorectal Cancers by Anatomical Locations.

BACKGROUND: H. pylori infection may play a role in the development of colorectal cancers (CRC). We aimed to examine the association between H. pylori infection and the risk of CRC by anatomical locations. METHODS: We conducted a case-control study on 91 incidence cases of CRC and 224 hospital controls. CRC was determined by histopathological examinations. H. pylori IgG antibody in serum was tested. We collected data on the diet, nutrition, and lifestyle by the validated semi-quantitative food frequency and demographic lifestyle questionnaire. The odds ratio and 95% confidence interval (OR (95%CI) were estimated for CRC and its subgroups. RESULTS: Overall 54.95% of CRC cases and 42.41% of the controls were H. pylori-seropositive, OR (95%CI): 1.56 (0.88, 2.74), p for trend=0.115. Positive dose-response association in quartiles, highest vs lowest, was observed for total CRC, OR (95%CI): 2.14 (1.00, 4.58), p for trend=0.049, for proximal colon, OR (95%CI): 1.52 (0.37, 6.25), p for trend=0.571), and for distal colon and rectum cancers combined, OR (95%CI): 2.38 (1.03, 5.50), p for trend=0.039. CONCLUSIONS: There is a positive association between H. pylori and colorectal cancers, especially distal colon and rectum cancers combined, but additional research is needed to determine the underlying mechanism of chronic H. pylori infection-induced CRC in humans.

Fruit and Vegetable Intake and Stomach Cancer among Male Adults: A Case-Control Study in Northern Viet Nam.

OBJECTIVE: This study investigated the association between fruit and vegetable intake and stomach cancer, with considering the impacts of Helicobacter pylori (H. pylori) infection and tobacco smoking. METHODS: A case-control study featuring 80 male incident stomach-cancer cases and 146 male controls was conducted in a general hospital in Viet Nam. A semi-quantitative food frequency and demographic lifestyle questionnaire were used; and venous blood samples were collected to determine H. pylori status by IgG ELISA. The respective associations between fruit and vegetable intake and stomach cancer were examined using unconditional logistic regression analysis with adjustments for possible cofactors. RESULTS: Fruit intake and stomach cancer showed a weak inverse association when this became non-significant after adjusting for H. pylori infection (OR = 0.50, 95%CI: 0.22-1.12, p trend = 0.094). Stratifying by H. pylori status returned a negative trend for fruit intake and stomach cancer among H. pylori-negative participants (OR = 0.21, 95%CI: 0.06-0.69, p trend = 0.010), but no significant interaction for H. pylori-positive participants (OR = 0.76, 95%CI: 0.21-2.68, p trend = 0.670). Vegetable intake and stomach cancer showed no association, regardless of H. pylori status. Compared to ever-smokers with low intake, never-smokers with high vegetable (OR = 0.25, 95% CI: 0.06-0.95) and fruit intake (OR = 0.20, 95%CI: 0.06-0.65) showed the lowest odds of stomach cancer. CONCLUSIONS: Fruit, but not vegetable, intake showed a weak inverse association with stomach cancer. H. pylori infection and tobacco-smoking status may influence the protective effects of fruit and vegetable intake on stomach cancer.

Nutritional status and feeding practices in gastrointestinal surgery patients at Bach Mai Hospital, Hanoi, Vietnam.

BACKGROUND AND OBJECTIVES: The nutritional status and hospital feeding practices of surgical patients in Vietnam are not well documented. Based on a cross-sectional study at Bach Mai Hospital (BMH), the prevalence of malnutrition was found to be 33% in the surgical ward using a body mass index (BMI<18.5 kg/m(2). We conducted an observational study over a three month period to evaluate the feeding practices in the gastrointestinal (GI) surgery ward at Bach Mai Hospital (BMH) in Hanoi, Vietnam. METHODS AND STUDY DESIGN: Investigators from the U.S. and the Vietnamese National Institute of Nutrition (NIN) enrolled 72 subjects admitted for elective GI surgery in an observational study at BMH. Baseline anthropometrics and changes over time, body mass index (BMI), Subjective Global Assessment (SGA) and daily kcal and protein intake from oral diet, tube feeding, and parenteral nutrition (PN) from admission until discharge were documented. RESULTS: A total of 50% of subjects scored a B or C on the SGA; 48% of subjects had a BMI<18.5, while mean mid upper arm circumference was in the lownormal range (24±4 cm). Nearly all patients (98%) were given PN postoperatively, with oral feeding starting on an average of postoperative day 4. Only one patient was tube fed. Mean daily total calorie intake was 15 kcal/kg/day and protein intake was 0.61 g/kg/day during hospitalization. Micronutrient supplementation was minimal in subjects receiving PN. CONCLUSIONS: Hospital malnutrition in surgical patients in Vietnam is a significant problem, peri-operative feeding appears suboptimal and use of early postoperative PN was routine.
