    Abstract Background/aim/aim: This study aimed to evaluate the regression pattern with the distal intramural spread (DIS) of rectum cancer after preoperative chemoradiation.
    Materials and methods: Specimens from 56 patients who underwent radical resection after preoperative chemoradiation for rectal cancer were examined. The regression pattern (total, fragmented) of the tumor was recorded. DIS status was evaluated by creating sections 0.2 to 0.3 cm thick.
    Results: A single macroscopic residual area was detected in all specimens. In 10 patients (17.8 %), pathologically complete responses were identified, and DIS was detected in 33 patients (58.9%). The average DIS distance was 0.56± 0.3 cm (range 0.2 – 1.8 cm); the spread was < 1 cm in 87.9% of the patients (29/33). The overall survival rates for 5 and 7 years were 76.8% and 73.2%, respectively. The survival rates between patients with and without DIS were not statistically different (94.6± 5.5 vs. 75.1 ± 10.2 months, respectively). In all of the patients, tumor regression pattern was total shrinkage of the tumor.
    Conclusion: A sufficient distal resection margin for rectal cancer after preoperative chemoradiation is 1 cm in the vast majority of cases. However, DIS may exceed 1 cm in a small proportion of patients.

    Abstract Background and aims: Pancreaticobiliary maljunction (PBM) is a malformation in which the pancreatic and bile ducts join outside the duodenal wall. It is associated with various biliary and pancreatic diseases. In addition, patients with PBM carry a substantial lifetime risk of developing biliary or gallbladder carcinoma. We aimed to present a multicenter case series of PBM from Turkey.
    Methods: This study was conducted in adult and pediatric PBM patients who were referred to three tertiary reference centers of Turkey for endoscopic retrograde cholangiopancreatography (ERCP) between July 2007 and May 2020. The clinical presentations, types of PBM, ERCP findings, surgical histories, and the postoperative courses, including the development of biliary malignancies, were retrospectively reviewed.
    Results: The study group included 47 (31 adult and 16 children) patients. Type D PBM was more frequent (13/41: 27.7%) than that reported in Eastern studies. Type A PBM was more common in the adults (51.6% vs. 12.5%, p < 0.05), whereas type C was more common in pediatric patients (31.3% vs. 13.2%, p < 0.05). Although fusiform anatomy was predominant in both of the groups, cystic dilatation was more common (25.8% vs. 12.5%) in adults and the common bile duct diameter was greater [22 mm (range 11-58) vs. 12 mm (range 5-33)] in adult patients compared to pediatric patients. Resective surgeries were more frequently done in pediatric patients (73.3% vs. 53.6%), whereas cholecystectomy was more frequently performed in adult patients (21.4% vs. 6.7%).
    Conclusion: Although our findings were compatible with Eastern studies, type D PBM (associated with pancreas divisum) was more frequent in our study population.

    Abstract Introduction: Diaphragmatic hernia secondary to traumatic rupture is a rare entity which can occur after stab wound injuries or blunt abdominal traumas. We aimed to report successfully management of dual mesh repair for a large diaphragmatic defect.
    Case report: A 66-year-old male was admitted with a right sided diaphragmatic hernia which occurred ten years ago due to a traffic accident. He had abdominal pain with worsened breath. Chest X-ray showed an elevated right diaphragm. Further, thoraco-abdominal computerized tomography detected herniation a part of the liver, gallbladder, stomach, and omentum to the right hemi-thorax. It was decided to diaphragmatic hernia repair. After an extended right subcostal laparotomy, a giant right sided diaphragmatic defect measuring 25×15cm was found in which the liver, gallbladder, stomach and omentum were herniated. The abdominal organs were reducted to their normal anatomic position and a dual mesh graft was laid to close the diaphragmatic defect. Patients' postoperative course was uneventful.
    Discussion: Diaphragmatic hernia secondary to trauma is more common on the left side of the diaphragm (left/right=3/1). A right sided diaphragmatic hernia including liver, stomach, gallbladder and omentum is extremely rare. The main treatment of diaphragmatic hernias is primary repair after reduction of the herniated organs to their anatomical position. However, in the existence of a large hernia defect where primary repair is not possible, a dual mesh should be considered.
    Conclusion: A dual mesh repair can be used successfully in extensive large diaphragmatic hernia defects when primary closure could not be achieved.

    Abstract Introduction: Situs inversus totalis (SIT) is a condition where the internal organs or organ systems are located contra-laterally to the norm, forming a mirror image. Laparoscopic sleeve gastrectomy (LSG) is an effective bariatric procedure that has become more common over the last two decades. We report on a morbidly obese patient with SIT who underwent a successful LSG.
    Case report: A 54-year-old female morbidly obese patient (136k; 167cm; body mass index (BMI): 48kg/m
    Discussion: SIT is a rare congenital condition, occurring in 1/10,000 to 1/50,000 live births. Organ function is generally normal, although it may sometimes be accompanied by respiratory or cardiovascular anomalies. Although undertaking LSG on morbidly obese patients with SIT may seem a daunting proposition at first, experienced laparoscopic surgeons can manage this operation with success.
    Conclusion: Although SIT is a rare congenital condition, LSG can be performed safely and effectively.

    Abstract Gastric cancer is one of the most common causes of cancer-related death. It requires multimodal treatment and surgery is the most effective treatment modality. Radical surgery includes total or subtotal gastrectomy with lymph node dissection. The extent of lymphadenectomy still remains controversial. Eastern surgeons have performed D2 or more extended lymphadenectomy while their Western colleagues have performed more limited lymph node dissection. However, the trend has been changing in favour of D2 lymph node dissection in both hemispheres. Currently, D2 is the recommended type of lymphadenectomy in experienced centres in the west. In Japan, D2 lymph node dissection is the standard surgical approach. More extensive lymphadenectomy than D2 has not been found to be associated with improved survival and generally is not performed. Bursectomy and splenectomy are additional controversial issues in surgical performance, and trends regarding them will be discussed. The performance of bursectomy is controversial and there is no clear evidence of its clinical benefit. However, a trend toward better survival in patients with serosal invasion has been reported. Routine splenectomy as a part of lymph node dissection has largely been abandoned, although splenectomy is recommended in selected cases. Minimally invasive surgery has gained wide popularity and indications for minimally invasive procedures have been expanding due to increasing experience and improving technology. Neoadjuvant therapy has been shown to have beneficial effects and seems necessary to provide a survival benefit. Diagnostic laparoscopy should be kept in mind prior to treatment.

    Abstract Background and objective: To evaluate the clinical role of the routine use of a drain in an elective laparoscopic cholecystectomy operation applied to patients with symptomatic cholelithiasis not showing acute inflammation.
    Method: Following laparoscopic removal of the gallbladder, patients were separated into two groups of 30 each, either with subhepatic drain placement or without. The presence of subhepatic fluid collection was evaluated with transabdominal ultrasonography (USG) at 24 hours postoperatively and on the 7th day. The other parameters evaluated were postoperative morbidity, shoulder and abdominal pain.
    Results: No statistically significant difference was found between the two groups in respect of demographic characteristics and operative details. The median pain score was determined to be statistically significantly higher in the group with a drain applied compared to the group without a drain (p=0.007). In the comparison between the groups of fluid collection on USG at 24 hours and shoulder pain persisting until the 7th day, although seen less in the group with no drain applied, no statistically significant difference was determined (p=0.065, p=0.159). In the examinations made on the 7th day, no hematoma or significant fluid collection was determined on USG and no wound infection was observed in any patient of either group.
    Conclusion: The routine application of prophylactic subhepatic drain in laparoscopic cholecystectomy procedure did not show any benefit to the patient.

    Abstract Laparoscopic cholecystectomy (LC) is seen as a gateway to minimally invasive surgery. We defined a new three-port technique with different port sites and compared the postoperative results with traditional four-port LC procedure in a case-match study. Between June 2012 and May 2013, 104 consecutive patients underwent three-port LC by same experienced surgeon. In the same center, 2963 consecutive patients underwent four-port LC, and of these 2963 patients, a matched group of 104 patients was selected. Data included patient age, gender, body mass index, American Society of Anesthesiologists score, history of abdominal operations, intraoperative data about operating time and conversion to open surgery, and postoperative data about length of hospital stay and postoperative complications were recorded prospectively. We concluded that our new three-port technique with different port sites is as feasible and safe as traditional four-port technique.

    Abstract Background: Several studies have documented human papillomavirus (HPV) in extra-cervical tumors. We aimed to detect HPV type 16 and HPV other than type 16 (OT-16) DNA in esophageal papilloma and esophagus squamous cell carcinoma (ESCC) samples and to compare clinicopathological features of HPV positive and negative patients.
    Methods: Materials were obtained from a tertiary care public hospital and studied in an university hospital for this cross-sectional study. Seventy-six tissue samples (50 papilloma and 26 ESCC) were included. After deparaffinization by xylene and DNA extraction by phenol chloroform-isoamyl-alcohol, 76 samples were studied with a G6PDH control kit. Forty-four papilloma and 21 ESCC samples with enough tissues were studied for HPV DNA. HPV OT-16 DNA and HPV type 16 were detected by real time-polymerase chain reaction.
    Results: Twelve (27.3%) and one (2.3%) of the papilloma samples were HPV type 16 and other than type 16 positive, respectively. Eleven (52.4%) and one (4.8%) of ESCC samples were HPV type 16 and mixed type positive, respectively.
    Conclusions: We suggest that HPV infection is common in esophageal papilloma and ESCC. Due to the wellknown association of HPV with premalignant and malignant conditions, follow-up of these patients accompanied by HPV should be implemented.

    Abstract Background/aims: Postoperative pancreatic fistula (POPF) is the most common cause of morbidity and mortality after distal pancreatectomy (DP). The aim of the present study is to determine the risk factors that can lead to POPF.
    Materials and methods: The study was conducted between January 2008 and December 2012. A total of 96 patients who underwent DP were retrospectively analyzed.
    Results: Overall, 24 patients (25%) underwent laparoscopic distal pancreatectomy (LDP) and 72 patients (75%) open surgery. The overall morbidity rate was 51% (49/96). POPF (32/96, 33.3%) was the most common postoperative complication. Grade B fistula (18/32, 56.2%) was the most common fistula type according to the International Study Group on Pancreatic Fistula definition. POPF rate was significantly higher in the minimally invasive surgery group (50%, p=0.046). POPF rate was 58.6% (17/29) in patients whose pancreatic stump closure was performed with only stapler, whereas POPF rate was 3.6% (1/28) in the group where the stump was closed with stapler plus oversewing sutures. Both minimally invasive surgery (OR: 0.286, 95% CI: 0.106-0.776, p=0.014) and intraoperative blood transfusion (OR: 4.210, 95% CI: 1.155-15.354, p=0.029) were detected as independent risk factors for POPF in multi-variety analysis.
    Conclusion: LDP is associated with a higher risk of POPF when stump closure is performed with only staplers. Intraoperative blood transfusion is another risk factor for POPF. On the other hand, oversewing sutures to the stapler line reduces the risk of POPF.
