Perforated peptic ulcer (PPU) is developed in 2%-10 % of peptic ulcer. The essential treatment is emergent surgical repair. Usually, the surgical repair with or without an omental patch is performed by laparotomy. The laparoscopic emergency surgery (LES) for PPU is increasingly being preferred with the innovation of laparoscopic devices and procedures and increase of surgeon’s expertise and experiences. Generally, a laparoscopic approach is recommended in stable patient. And, in selected patient with instability, a laparoscopic approach may be adopted. The patient selection criteria is recommended in hemodynamic stability, surgeon’s skills, cardiovascular or pulmonary comorbidity and Boey score. These LES rate differences for PPU are resulted that the variability in the healthcare infrastructure and patient-related factors between countries. The surgeon’s decision about LES for PPU is affected by various factors. Even surgeon’s fatigue, physical strength, stressful feelings and poor emotional mood may be one of factors. According to published literature, the practical LES performance is affected by various limiting factors. Although guideline about laparoscopic emergency knotless suture repair for PPU is absent, the 4 retrospective studies about LES for PPU between knotless and interrupted suture repair revealed that the laparoscopic knotless suture repair using barbed suture material is alternative, feasible, safe, simple and non-inferior method. However, the recommendation evidence about single port LES for PPU is unclear.

Small bowel bleeding (SBB) accounts for 5%-10% of all gastrointestinal bleeding (GIB) cases. Several diagnostic modalities in SBB are performed. However, the small bowel is beyond the reach of these diagnostic modalities. A large amount of bleeding in GIB is a key factor leading to a poor prognosis. Appropriate and prompt diagnostic and treatment strategies are needed. Several diagnostic and management algorithms have been proposed. However, the processing of algorithm is complex and frequent mistakes are happened. Because of surgical aspects and sudden or gradual development of hemodynamic instability in SBB, algorithms considering surgical role and treatment have been published. The intra-operative enteroscopy (IOE) is a gold-standard method for detecting lesions in SBB. The primary goal of IOE is to detect specific bleeding focus in SBB. The determining the resection range is the secondary goal. In most cases in SBB, segmental resection is treatment of choice. However, in bleeding distal duodenum from distal to the ampulla of Vater to Treitz ligament, pancreas preserving distal duodenectomy could be performed. In terminal ileum bleeding, after resection of pathologic bowel, the reconstruction option is ileo-colic anastomosis or end enterostomy. Because of frequently developed postoperative morbidity and mortality, post-operative critical care is perfectly fit for an acute care surgeon’s role. Therefore, in the entire management process, an interprofessional team or multidisciplinary approach is critical for improving the quality of care of SBB and decreasing mistakes.

The retroperitoneum is a posterior space of the peritoneum, which has many visceral and vascular structures. Spontaneous retroperitoneal hemorrhages have variable causes, the most common of which are diseases of retroperitoneal organs. However, retroperitoneal hemorrhages may be caused by bare area injury. In this case study, a bare area was observed in the right upper quadrant (RUQ) of the retroperitoneum, the posterosuperior region of Couinaud liver segment 7 (bare area) is directly connected to the anterior pararenal space. The rupture or exophyte of the hepatocellular carcinoma on the bare area could invade the retroperitoneum, which may lead to inaccurate diagnosis of the condition. When the mass or the hemorrhage in the RUQ of the retroperitoneum is observed in computed tomography images, it is possible that ruptured hepatocellular carcinoma or a mass on the bare area of the liver, looks like a spontaneous retroperitoneal hemorrhage in the RUQ area for example a right adrenal hemorrhage.
