Symptom Duration and Surgeon Volume: Impact on Early Laparoscopic Cholecystectomy for Acute Cholecystitis.

BACKGROUND: The 'golden 72 hours' rule from the onset of symptoms still applies in laparoscopic cholecystectomy for acute cholecystitis. This rule has been discussed with increasing experience in laparoscopic surgery in recent years. OBJECTIVE: This study aims to determine the optimal symptom duration based on the surgeon's volume when deciding on early laparoscopic cholecystectomy for acute cholecystitis. MATERIALS AND METHODS:  The patients were categorized into two groups: Group 1 (≤3 days) and Group 2 (>3 days) based on the symptom duration, and high-volume surgeons (performing >100 laparoscopic cholecystectomies in a year) and low-volume surgeons (performing <100 laparoscopic cholecystectomies in a year) based on the surgeon volume. All surgeons had received advanced training in laparoscopic surgery. RESULTS: There was no statistical difference in postoperative outcomes between groups, except for a few data (p>0.05). The operative time was longer in Group 2, the postoperative hospital stay was longer for low-volume surgeons than for high-volume surgeons after three days, and operative time was longer after three days than the first three days in low-volume surgeons (p<0.05). CONCLUSIONS: Early laparoscopic cholecystectomy may be recommended for acute cholecystitis with symptom duration of more than three days, regardless of the surgeon volume, as long as they are competent in laparoscopic surgeries.

A New Risk Scoring System to Predict Malignancy in Gallbladder Polyps: a Single-Center Study.

OBJECTIVE: Ultrasonography (US) is the most commonly used radiological method in the diagnosis of gallbladder polyps (GBPs). Patients diagnosed with GBPs on US are operated on with risk factors that do not have a high level of evidence. Our aim in this study is to determine the sensitivity of US in diagnosis GBPs, to define risk factors for neoplastic (NP) polyps, and to develop the risk scoring system. MATERIALS AND METHODS: Between July 2011 and July 2021, 173 patients who were found to have GBPs in the pathology specimens after cholecystectomy were included in the study. Patients were divided into two groups: nonneoplastic and NP groups. RESULTS: GBPs in patients who underwent abdominal US for any reason was 4.5%. The sensitivity of US in the diagnosis of GBPs was 56.6%. Comparison between groups, age ≥50, presence of symptoms, polyp size >12.5mm, single polyp, concomitant gallstones, and gallbladder wall thickness ≥4mm were statistically in the NP group. A risk scoring system was developed using these values. If the risk score was <4, 0.6% of GBPs was NP polyps. If the risk score was ≥4, 63.2% of GBPs were NP polyps. CONCLUSION: Our risk scoring system can prevent unnecessary choelcystectomy. Because the incidence of NP polyps in low-risk patients (risk score <4) is extremely rare.

Comparison of the Pretzelflex Retractor and Nathanson Retractor in Laparoscopic Sleeve Gastrectomy Surgery.

PURPOSE: Retraction of the left lobe of the liver is an important step in most bariatric surgical procedures. The left lobe of the liver may be enlarged, and laceration, hematoma, or necrosis may develop in the liver due to retraction. In this study, the results of use of the Nathanson retractor (NR) and PretzelFlex retractor (PFR) in the patients undergoing laparoscopic sleeve gastrectomy (LSG) were compared. MATERIALS AND METHODS: The patients who underwent LSG were divided into three groups based on the type of liver retraction device used. Group 1: NR was used fixed during the operation; Group 2: PF retractor was used; Group 3: NR were used only for fundus dissection and when necessary. All groups were evaluated in terms of demographic characteristics, liver function tests, and developing complications. RESULTS: The study was conducted with a total of 120 consecutive patients. Operation time in the second group was found to be significantly lower than the other two groups (p = 0.009; p = 0.001; p < 0.01). The duration of retractor use in the first group was significantly higher than the other two groups (p = 0.001; p = 0.001; p < 0.01). While aspartate aminotransferase (AST) values were found to be high in Group 1, alanine aminotransferase (ALT) values were found to be high in Groups 1 and 3. CONCLUSION: PFR has shorter operating and retraction times. It causes less measurable liver damage. Although the NR will be used, intermittent use causes less damage to the liver as in PFR.

The Effect of Helicobacter pylori Eradication on Gastric Wall Thickness in Patients Undergoing Laparoscopic Sleeve Gastrectomy.

PURPOSE: The most important cause affecting the thickness of the gastric wall other than the tumor is chronic gastritis caused by Helicobacter pylori (Hp), which is most frequently detected in the antrum. This study aims to investigate the effect of bismuth-based treatment (BBT) combined with proton pump inhibitor (PPI) on wall thicknesses measured in the postoperative gastric specimen and early postoperative complications in patients with Hp-positive pre-LSG endoscopic gastric biopsies. MATERIALS AND METHODS: The patients who underwent LSG procedure for morbid obesity were divided into three groups as follows: Hp-negative, Hp-positive without eradication treatment, and Hp-positive, and LSG was performed after eradication treatment. Macroscopic and microscopic gastric wall thickness measurements were made at a distance of 1 cm from the proximal surgical margin, from the middle part of the specimen, and 1 cm from the distal surgical margin in the gastric specimen and the results were compared. RESULTS: A total of 132 patients were included in the study, 44 patients in each group. Microscopically measured antrum mucosal thickness was found to be statistically significantly higher in group 2 compared to other groups (groups 1.15, 1.35, 1.16 mm, respectively, p = 0.000). There was no difference between the groups in terms of early complications such as bleeding, wound site infection, or leakage from the staple line within the first 28 days after surgery. CONCLUSION: This study found that LSG had no effect on early complications due to Hp positivity or eradication of Hp. KEY POINTS: • The presence of HP increases the wall thickness of the gastric antrum mucosa. • After HP eradication, stomach antrum wall thickness returns to normal. • HP eradication before LSG reduces the wall thickness of the gastric antrum mucosa. • It was determined that HP scanning and eradication before LSG had no effect on postoperative complications.
