Publication Metadata only Enhanced recovery after pancreatic surgery: A prospective randomized controlled clinical trial(WILEY, 2021) ERGENÇ, MUHAMMER; Ergenc, Muhammer; Karpuz, Sakir; Ergenc, Merve; Yegen, CumhurBackground and Objectives The enhanced recovery after surgery (ERAS) protocol is a perioperative care bundle designed to achieve early healing after surgical procedures. This study aims to investigate the effect of the ERAS protocol on postoperative complications, length of hospital stay (LOS), and readmission rates in pancreatic surgery patients. Methods The study was designed as a prospective and randomized controlled study between January 2016 and November 2018 on pancreatic surgery patients. A total of 38 patients were analyzed, 18 of whom were in the ERAS group and 20 in the control group. Patient demographics, intraoperative variables, and postoperative outcomes were recorded. Results The groups were similar regarding age, sex, surgery type, American Society of Anesthesiologists scores, and laboratory results. There was no significant difference in the intraoperative variables. Early oral feeding was preferred, mostly in the ERAS group compared to the control group. Perioperative complication rates, including delayed gastric emptying and pancreatic fistula, LOS, and readmission rates, were similar between the two groups. Conclusions The ERAS protocol provided a minimal decrease in the total complication rates and had no effect on severe complications. Therefore, the ERAS protocol seems feasible and can be applied safely in pancreatic surgery patients.Publication Metadata only Turkish surgical association annual congress abstract supplement(2018-04-01) ERGENÇ, MUHAMMER; UPRAK, TEVFİK KIVILCIM; YEGEN, ŞEVKET CUMHUR; ATICI, ALİ EMRE; DEMİRBAŞ, BAHA TOLGA; Ergenç M., Uprak T. K., Yegen Ş. C., Atıcı A. E., Demirbaş B. T.Patient with Peutz-Jeghers Syndrome Presenting with Inoperable Periampullary TumorMuhammer Ergenç, Tevfik Kıvılcım Uprak, Şevket Cumhur YeğenDepartment of General Surgery, Marmara University School of Medicine, İstanbul, TurkeyIntroduction:Peutz-Jeghers syndrome (PJS) is an autosomal dominant inherited genetic syndrome characterized by multiple hamartomatous polyps and mucocutaneous pigmentation in the gastrointestinal tract. In patients with Peutz-Jeghers syn- drome, the risk of gastrointestinal and non-gastrointestinal malignancies is increased.Case:The patient, who had complaints of weight loss, nausea and vomiting for about 2 months was admitted to the emergency service and then referred to the general surgery unit for further examination and treatment. The patient’s physical examination revealed no evidence of defense-rebound in the abdomen, palpable mass lesions in the periumbilical region were present, and hyperpigmented areas were observed on the lips. The patient had undergone laparotomy about 25 years ago and had no knowl- edge about the reason. In laboratory tests; WBC was 14200, HGB was 10,6, Creatine was 1,51, Albumin was 3,6, and Bilirubin was N. A 10 cm mass at the head of the pancreas was detected in the tomography of the abdomen and the stomach was in a pitotic state. Upper gastrointestinal endoscopy showed polypoid appearance in the stomach fundus, pylorus could not be passed. The exploratory laparotomy was performed. At the head of the pancreas, all the retroperitoneal area filled with tumoral lesion was palpated. Implants on the gall bladder and hepatoduodenal ligaments were observed. Multiple invagination sites were observed in the small intestines and the polyps were palpated after being reduced. Multiple enterotomies were performed and polyps were excised. Gastrojejunostomy was performed on the patient due to duodenal obstruction secondary to lack of oral intake. The implants were biopsied and the operation was terminated. The patient who started the regimen on the postopera- tive 2nd day passed gas on the 3rd day. On the 4th day, the patient who started tolerating the regimen was discharged from the hospital. According to the patient`s pathology, the implants were reported to be compatible with mucinous adenocarcinoma and multiple hamartomatous small intestine polyps.Conclusion:The patient was examined with the pre-diagnosis of gastric outlet obstruction and was detected a mass on the head of the pancreas. The patient was diagnosed with PJ syndrome with multiple PJS type polyps and characteristic pigmenta- tions on the lips. Pancreatic cancer has been reported in 11-36% of patients with Peutz-Jeghers syndrome. Patients and their relatives were informed about PJS family screening.Mass in the Right Lower Quadrant; Retroperitoneal Localized Gastrointestinal Stromal TumorMuhammer Ergenç, Tevfik Kıvılcım Uprak, Şevket Cumhur YeğenDepartment of General Surgery, Marmara University School of Medicine, İstanbul, TurkeyIntroduction:Gastrointestinal stromal tumors (GIST) develop from Cajal cells, which are pacemaker cells responsible for the adjustment of peristalsis in the digestive tract. The prevalence is 7-15 per million. GISTs can be seen in all gastrointestinal tract, in order of frequency; stomach (60%), jejenum and ileum (30%), duodenum (5%) and colorectal (5%). Small intestine GISs may present with a small nodule or a giant tumoral mass. Although the clinical symptoms and signs are generally nonspecific, they may cause gastrointestinal bleeding, intestinal obstruction, pelvic mass, acute pain like appendicitis, tumor rupture and acute abdomen.Case:A 58-year-old woman was admitted to the general surgery outpatient unit with a complaint of abdominal pain. Physicalexamination was unremarkable. In the abdominal USG, a well-defined hypervascular solid lesion 19x19x21 mm in size, in theright lower quadrant of the abdomen was observed; its origin could not be detected. Abdominal computed tomography showed a 21x23 mm lesion in the right lower quadrant adjacent to the psoas muscle. Laparoscopic exploration was performed. Retroperi- toneal area was entered from the ileocecal region. Retroperitoneal area was opened and surrounding of the mass was cleaned and the lesion that was found to be ileum wall originated was resected via endostapler and the operation was terminated. The patient who was comfortable during the abdominal examination on the postop 1st day was started a diet and the patient was discharged. Pathology was reported as 3.5 cm in size, gastrointestinal stromal tumor, with spindle cell, in low risk group.Conclusion:In patients presenting with a mass in the right lower quadrant, the ileal gist should be kept in mind. Laparoscopic mass excision can be performed safely.Our Laparoscopic Splenectomy Experience in Patients with Idiopathic Thrombocytopenic Purpura (ITP) DiagnosisBaha Tolga Demirbaş, Muhammer Ergenç, Ali Emre Atıcı, Şevket Cumhur YeğenDepartment of General Surgery, Marmara University Pendik Hospital, İstanbul, TurkeyObjective:ITP is an autoimmune etiology characterized by blood platelets below 100000/mm3. Its prevalence in the community is 4,000 per 100000. Patients who do not respond to steroid and intravenous immunoglobulin therapy have an indication of sple- nectomy. Laparoscopic splenectomy has been successfully performed in recent years with ITP patients with normal size spleen.Material and Methods:A total of 23 ITP patients underwent laparoscopic splenectomy at Marmara University Pendik Train- ing and Research Hospital between May 2012 and January 2018. The data of these patients were analyzed retrospectively. Of the patients who underwent laparoscopic splenectomy, 12 of them were female and 11 of them were male. The median age of the patients was 33 years. The mean duration of hospitalization of the patients was 4.1 days. No mortality was observed in any patient. Intraoperative and postoperative bleeding were minimal. Therefore, blood transfusion was not required. Atelectasis developed in 1 patient as morbidity.Results:Idiopathic thrombocytopenic purpura is a hematological disease characterized by autoimmune etiology, mucocutane- ous bleedings and low platelet counts. The cause of the disease is the formation of autoantibodies against platelets. Therefore, platelets are rapidly destroyed in the spleen and mucocutaneous and petechial hemorrhages occur as a result of thrombocyto- penia. Hemorrhage may give symptom in the form of menometrorrhagia in gingivas as hematuria or melena. The risk of intracra- nial hemorrhage is high when the platelet count falls below 10000/mm3. The first-line treatment of the disease is 1 mg/kg/day prednisone treatment. Relapses are quite common after 3 weeks of treatment. In this case, intravenous immunoglobulin treat- ment may be given. However, splenectomy is necessary if it does not respond to this treatment. Platelet counts rapidly increase to normal levels after splenectomy in 75-85% of the patients. However, complications such as surgical site infection, pancreatitis and hemorrhage can be seen in 15-20% of patients receiving steroid therapy, with immunosuppressive effect, for a long time before the surgery. Therefore, the application of minimally invasive surgery in patients with ITP suggests that good results can be obtained. In our series, the morbidity rate was 4%. No intraoperative bleeding occurred. We had no mortality.Conclusion:Laparoscopic splenectomy can be performed safely in elective conditions in patients with ITP.Publication Open Access Prognostic significance of metastatic lymph node ratio in gastric cancer: a Western-center analysis(2023-08-01) UPRAK, TEVFİK KIVILCIM; AKIN, MUHAMMED İKBAL; ÇELİKEL, ÇİĞDEM; YEGEN, ŞEVKET CUMHUR; ERGENÇ, MUHAMMER; Ergenç M., Uprak T. K., Akın M. İ., Hekimoğlu E. E., Çelikel Ç., Yegen Ş. C.BackgroundTumor-node-metastasis (TNM) staging is the central gastric cancer (GC) staging system, but it has some disadvantages. However, the lymph node ratio (LNR) can be used regardless of the type of lymphadenectomy and is considered an important prognostic factor. This study aimed to evaluate the relationship between LNR and survival in patients who underwent curative GC surgery.MethodsAll patients who underwent radical gastric surgery between January 2014 and June 2022 were retrospectively evaluated. Clinicopathological features of tumors, TNM stage, and survival rates were analyzed. LNR was defined as the ratio between metastatic lymph nodes and total lymph nodes removed. The LNR groups were classified as follows: LNR0 = 0, 0.01 < LNR1 ≤ 0.1, 0.1 < LNR2 ≤ 0.25 and LNR3 > 0.25. Tumor characteristics and overall survival (OS) of the patients were compared between LNR groups.ResultsAfter exclusion, 333 patients were analyzed. The mean age was 62 ± 14years. According to the LNR classification, no difference was found between groups regarding age and sex. However, TNM stage III disease was significantly more common in LNR3 patients. Most patients (43.2%,n = 144) were in the LNR3 group. In terms of tumor characteristics (lymphatic, vascular, and perineural invasion), the LNR3 group had significantly poorer prognostic factors. The Cox regression model defined LNR3, TNM stage II—III disease, and advanced age as independent risk factors for survival. Patients with LNR3 demonstrated the lowest 5-year OS rate (35.7%) (estimated mean survival was 30 ± 1.9months) compared to LNR 0–1–2.ConclusionOur study showed that a high LNR was significantly associated with poor OS in patients who underwent curative gastrectomy. LNR can be used as an independent prognostic predictor in GC patients.Publication Open Access Outcomes of proximal versus total gastrectomy for proximal gastric cancer: A propensity score-matched analysis of a western center experience(2023-01-01) UPRAK, TEVFİK KIVILCIM; ERGENÇ, MUHAMMER; AKMERCAN, AHMET; YEGEN, ŞEVKET CUMHUR; UPRAK T. K., ERGENÇ M., AKMERCAN A., YEGEN Ş. C.Purpose: In this western study, we aimed to compare perioperative outcomes, postoperative complications, and overall survival in patients who underwent total gastrectomy (TG) or proximal gastrectomy (PG) for proximal gastric cancer (GC). Methods: Patients who underwent GC surgery at Marmara University Hospital between January 2014 and December 2021 were evaluated retrospectively. Propensity score matching (PSM) was performed to balance the baseline characteristics of patients undergoing PG and TG. Data on patients’ demographics, clinicopathological features of tumors, complications, and survival rates were analyzed. Perioperative outcomes and overall survival of the patients were compared between PG and TG groups. Results: A total of 212 patients were included in this study, with 53 patients in the PG and 159 in the TG group. After 1:1 matching according to PSM, 46 patients in the PG group were matched to 46 in the TG group. After PSM, there were no differences in clinicopathological outcomes except retrieved lymph nodes. In terms of short-term outcomes, overall perioperative morbidity (Clavien Dindo ≥ 3a) was significantly higher in the PG group (p = 0.01). However, there was no significant difference when the complications were considered separately. In the long-term follow-up, reflux esophagitis was associated with the PG group (p=0.04). In multivariate analysis, positive surgical margin and lymphovascular invasion were significant factors related to overall survival. Overall, 5-year survival was 55% in matched patients. The difference in survival was not statistically significant (57 vs. 69 months, p = 0.3) between the two groups. Conclusions: Proximal gastrectomy is applicable to patients up to stage 3 disease, with no difference in overall survival, with caution in early complications and reflux esophagitis. Among all demographic and oncological factors, lymphovascular invasion and resection margin were significantly associated with worse survival.Publication Metadata only Pankreas cerrahisi yapılan hastalarda eras uygulamasının etkisi(2021-06-14) ERGENÇ, MUHAMMER; KARPUZ, ŞAKİR; YEGEN, ŞEVKET CUMHUR; Ergenç M., Karpuz Ş., Ergenç E. M., Yegen Ş. C.Amaç:Cerrahi sonrası hızlandırılmış iyileşme (ERAS: Enhanced Recovery After Surgery) hastaya detaylı eğitim verilerek ve hasta güvenliği gözetilerek uygulanan, perioperatif dönemde intravenöz hidrasyonun kısıtlanması, postoperatif erken oral rejim başlanarak sıvı ihtiyacını bu yolla giderilmesi, daha etkin analjezi sağlanması, yerleştirilen drenlerin daha erken çekilmesi ve hastanın erken mobilize edilmesi esasına dayanan bir protokoldür. Son dekadda tanımlanan bu protokol ile elektif cerrahiler sonrası hastanede yatış sürelerinin kısaltılması ve ilişkili komplikasyonların azaltılması hedeflenmiştir. Bu çalışmada ERAS protokolünün pankreas cerrahisi hastalarında postoperatif komplikasyonlar, yatış süresi, tekrarlayan hastane yatışı ve reoperasyon oranlarına etkisinin araştırılması hedeflenmiştir.Gereç ve Yöntem:Çalışma Ocak 2016 ile Kasım 2018 tarihleri arasında Marmara Üniversitesi Pendik Eğitim Araştırma Hastanesi Genel Cerrahi Kliniği’nde laparotomi ile elektif pankreas kanseri cerrahisi geçiren hastalar üzerinde prospektif olarak yapılmış olup hastalar standart bakım ve ERAS protokolü esasına göre iki gruba randomize edildi. Hastaların demografik verileri, laboratuvar tetkik sonuçları ile birlikte perioperatif verilen sıvı miktarı, kanama ve transfüzyon durumu kaydedildi. Postoperatif sonda çekilme günleri, ağrı ve gelişen komplikasyonlar ve taburculuk günleri takip edilerek kaydedildi.İstatistiksel analizde sayısal değerler için nonparametrik t testi, kategorik değerler için ki kare kullanıldı.Bulgular:On sekizi ERAS protokolü, 20’si standar t bakım protokolü olmak üzere toplam 38 hastanın verileri istatiksel analize dahil edildi. Gruplar yaş cinsiyet, laboratuvar değerleri, cerrahi tipi ve ASA skorları açısından benzer dağılmaktaydı. Ameliyat süresi, ameliyatta verilen iv sıvı ve transfüzyon açısından fark saptanmadı. Kanama miktarı ERAS grubunda median değer 300 ml (100-550) iken, kontrol grubunda 500 ml (200-750) bulundu. Postoperatif takipte; günlük verilen iv sıvı ortalaması, nazogastrik çekilme günü, postoperatif vizüel analog skala skoru değerleri, mobilizasyon, postop gaz çıkışı ve defekasyon yönünden ERAS ve kontrol grubu arasında fark yoktu. ERAS gurunda tüm hastalara epidural analjezi uygulanırken kontrol grubunda uygulanmadı. ERAS grubunda 17 (%94) hastaya erken beslenme uygulanırken bu oran kontrol grubunda 11 (%55) idi. En sık gelişen komplikasyonlar olan gecikmiş mide boşalması ve pankreatik fistül dahil olmak üzere postoperatif komplikasyon açısından iki grup arasında fark izlenmedi. Çalışmanın primer çıkarımı olan hastanede kalma süresi ve yeniden yatış açısından ERAS ve kontrol grubu arasında anlamlı fark izlenmedi.Sonuç:Sunulan çalışmada ERAS uygulamalarının total komplikasyon oranını azalttığı, özellikle abdominal enfeksiyon, hastane yatış süresi, mide boşalma güçlüğü gibi hafif olanları etkilerken, pankreas fistülü, reoperasyon, tekrar yatış ve mortalite gibi ağır olanlar üzerine etkisi olmadığı ortaya konulmuştur. Bu uygulamaların başlatılması pankreas cerrahisi için güvenlik tehdidi oluşturmamaktadır.Anahtar kelimeler:Pankreas cerrahisi, Cerrahi sonrası hızlandırılmış iyileşme, ERASPublication Open Access Pancreaticoduodenectomy in patients < 75 years versus ≥ 75 years old: a comparative study(2024-12-01) ERGENÇ, MUHAMMER; UPRAK, TEVFİK KIVILCIM; KARPUZ, ŞAKİR; COŞKUN, MÜMİN; YEGEN, ŞEVKET CUMHUR; ATICI, ALİ EMRE; ERGENÇ M., UPRAK T. K., Özocak A. B., KARPUZ Ş., COŞKUN M., YEGEN Ş. C., ATICI A. E.Objective: This study aimed to compare the postoperative outcomes of < 75-year-old patients and ≥ 75-year-old patients who underwent pancreaticoduodenectomy (PD) for pancreatic head and periampullary region tumors. Methods: Patients who underwent PD in our hospital between February 2019 and December 2023 were evaluated. Demographics, Eastern Cooperative Oncology Group Performance Status (ECOG-PS) scores, American Society of Anesthesiologists (ASA) scores, comorbidities, hospital stays, complications, and clinicopathological features were analyzed. Patients were divided into < 75 years (Group A) and ≥ 75 years (Group B) groups and compared. Results: The median age of the entire cohort (n = 155) was 66 years (IQR = 16). There was a significant difference between Group A (n = 128) and Group B (n = 27) regarding the ECOG-PS and ASA scores. There was no significant difference between the groups regarding postoperative complications. The 30-day mortality rate was greater in Group B (p = 0.017). Group B had a cumulative median survival of 10 months, whereas Group A had a median survival of 28 months, with a statistically significant difference (p < 0.001). When age groups were stratified according to ECOG-PS, for ECOG-PS 2–3 Group A, survival was 15 months; for ECOG-PS 2–3 Group B, survival was eight months, and the difference was not statistically significant (p = 0.628). Conclusions: With the increasing aging population, patient selection for PD should not be based solely on age. This study demonstrated that PD is safe for patients older than 75 years. In older patients, performance status and the optimization of comorbidities should be considered when deciding on a candidate’s suitability for surgery.
