Feasibility of laparoscopic resection for perforated diverticulitis: a retrospective observational study of 77 consecutive patients.

Background: Perforated colonic diverticulitis with purulent or fecal contamination (PCD) is a surgical emergency with high morbidity and mortality. Traditionally, open surgery as a Hartmann procedure (HP) has been performed. Feasibility of the laparoscopic approach (LA) either with primary anastomosis (PA) or as an HP has been shown, but evidence and implementation into daily routine remain low.

Access to Surgery and Quality of Care for Acute Cholecystitis During the COVID-19 Pandemic in 2020 and 2021 - an Analysis of 12,545 Patients from a German-Wide Hospital Network.

Purpose: To determine effects on admission, treatment, and outcome for acute cholecystitis during the course of the COVID-19 pandemic in 2020 and 2021.

Methods: Retrospective analysis of claims data from 74 German hospitals. Study periods were defined from March 5, 2020 (start of first wave) to June 20, 2021 (end of third wave) and compared to corresponding control periods (March 2018 to February 2020).

The transversus abdominis plane block may reduce chronic postoperative pain one year after TAPP ingunial hernia repair.

Introduction: Chronic postoperative inguinal pain (CPIP) is defined as pain impacting daily activities lasting at least 3 months. With an incidence of 0.5-6.

Adenocarcinoma of an ileal conduit developing 8 years after cystoprostatectomy for locally advanced prostate carcinoma.

A 70-year-old patient was treated in September 2017 for a malignancy in an ileal conduit (IC) which he received in 2009 for the treatment of prostate cancer. The tumour was found incidentally during a routine sonography. A CT scan revealed a mass near the IC.

Abdominal Abscesses and Destruction of Inguinal Canal with Mesh Dislocation caused by a Perforated Diverticulitis.

The diverticulitis is a frequent disease of the gastrointestinal tract. It may lead to a variety of severe complications. In some cases, it has to be surgically treated.

[Avoiding Clustering and Urge in Transanal Surgery for Deep Distal Rectocele].

Discrimination between functional and morphological influences in obstructive defecation syndrome is challenging. The predictability of surgical success is still in discussion. Final understanding of the rectally induced variability in colonic motility is still missing, so that morphological changes cannot solely serve as indication.

Malignant intestinal obstruction during twin pregnancy: surgical resection of a myxoid liposarcoma without induction of labour.

Myxoid liposarcoma (MLS) represents one of the three main morphological subgroups of liposarcomas. Extrapulmonary recurrence to the retroperitoneum and abdomen is common in MLS. A pregnant patient was referred to our hospital due to abdominal pain and obstipation.

Patient reported outcome following incisional hernia repair: A survey on 163 patients at two maximum care hospitals.

Introduction: Incisional hernias of the abdominal wall are frequent complications after laparotomy (9-20%) and often need incisional hernia repair (IHR). In order to ensure wound healing and to therefore prevent postoperative short and long term morbidity carrying an abdominal binder (AB) and physical rest is frequently advised. However, there is a lack of evidence concerning clinical effects regarding these recommendations.

Mesenchymal chondrosarcoma metastasising to the pancreas.

The mesenchymal chondrosarcoma (MC) is a rare malignant tumour and accounts for less than 3% of primary chondrosarcomas. Mostly MC arises from the craniofacial bones, the ribs, the ilium, the femur and the vertebrae. A 54-year-old man was treated due to an icterus of unknown origin.

Postoperative-treatment following open incisional hernia repair: A survey and a review of literature.

Introduction: Incisional hernias of the abdominal wall are frequent complication after laparotomy (9-20%). Open incisional hernia repair with sublay mesh placement (SMP) on the posterior rectus sheath is described as being a sufficient method for repairing incisional hernia. In order to ensure wound healing and to therefore prevent recurrence, carrying an abdominal binder (AB) or a pressure dressing (PD) and physical rest for a certain time is the common postoperative recommendation, though the evidence for post-operative treatment is low.

Liver abscess and sepsis caused by Clostridium perfringens and Klebsiella oxytoca.

Introduction: Clostridium (C) perfringens and Klebsiella (K) oxytoca are pathogenous human bacteria. Due to the production of several toxins C. perfringens is virulent by causing i.

[Register of Difficult Surgical Situations].

Every surgical problem that increases the likelihood of intraoperative and postoperative complications is considered to be a difficult surgical situation. Based on this definition, Korenkov et al. proposed to classify patients according to the following intraoperative difficulty levels (I to IV): (I) ideal situation (easy to operate, no problems), (II) fairly easy/manageable/simple (some minor difficulties may occur), (III) difficult/problematic (difficult to operate; some operative techniques are considerably more difficult than others), and (IV) very difficult (every operative step is difficult/challenging).

Abdominal surgery in pregnancy--an interdisciplinary challenge.

Background: Abdominal operations are performed during ca. 2% of all pregnancies. They represent an unusual situation not only for the patient, but also for the involved surgeons and anesthesiologists.

Ultrastaging of colon cancer by sentinel node biopsy using fluorescence navigation with indocyanine green.

Purpose: Lymph node status is the most important prognostic factor in colon cancer, but the role of sentinel lymph node biopsy (SLNB) as a tool for identification of micrometastatic disease and extraanatomical lymph nodes for adjuvant strategies and a tailored approach still remains unclear. Indocyanine green (ICG) fluorescence detection is a new method for SLNB allowing real-time lymphography and lymph node detection. This study was designed to evaluate the feasibility of fluorescence-guided sentinel lymph node detection in colon carcinoma.

Hepato-pericardial fistula following radiofrequency ablation (RFA) for liver metastasis: a case report and review of the literature.

Introduction: Recent large-scale studies have demonstrated the efficiency and safety of radiofrequency ablation (RFA) for unresectable hepatic tumors. Nevertheless, severe side effects especially relating to non-target thermal injury have occurred after radiofrequency ablation.

Case Report: We observed the development of a hepato-pericardial fistula leading to pericardial empyema after RFA of a metastatic hepatic lesion.

VEGF isoforms and mutations in human colorectal cancer.

We wished to demonstrate vascular endothelial growth factor (VEGF) transcript polymorphism in human colon cancer. RNA was extracted from 25 primary human colorectal adenocarcinomas followed by VEGF transcript amplification, fragment elution, subcloning, positive selection via insert analysis and sequencing. Four distinct splice variants were consistently expressed in cancer, including VEGF121, VEGF165, VEGF189 and the newly identified truncated splice variant VEGF145.

Vascular closure staples-a new technique for biliary reconstruction: prospective randomized comparison with manual suture in an animal model.

Background: In orthotopic liver transplantation the incidence of biliary complications is up to 49%. In view of the relative frequency of such complications despite seemingly good preconditions, method-related disadvantages of conventional suture must also be considered as a possible cause. These include perforating needle injury of the choledochal wall with at least temporary exposure of suture material in the lumen, suboptimal approximation of the mucosa, and an additional decrease in blood flow in the choledochal stumps as a result of suture-related tissue strangulation.
