<p style="text-align: justify;">This restrospective study reviewed 60 cases of histologically documented gastric cancer admitted at the Davao Medical Center. There were 39 (65%) males and 21 (35%) females. Epigastric pain and pallor were the most common initial complaints and findings on admission. Sixty per cent of the patients presented as acid peptic disease and only 40 per cent were correctly diagnosed upon admission. Diagnosis was verified by endoscopy with biopsy in 68.3 per cent of cases. Forty two per cent of the lesions were found at the antrum and 32 per cent were noted in the proximal stomach. Using the TNM staging, 92 per cent had stage III and IV tumor and only 8 per cent were stage II. Most patients underwent palliative surgery (73.3%) with resections for cure limited to 23.3 per cent. Ninety nine per cent were adenocarcinoma, confirmed histopathologically. The associated perioperative complications were noted, with morbidity and mortality rates at 26.67 and 5 per cent, respectively. (Author)p>

The clinical presentation of Boerhaave’s syndrome (BS), a rare condition of the gastrointestinal tract characterized by a spontaneous rupture of the esophagus most often caused by vomiting after excessive alcohol drinking or after consuming a large meal, mimics other less serious illnesses, often leading to a missed or delayed diagnosis. The Mackler triad, which is rare and pathognomonic of BS, includes lower thoracic or chest pain, subcutaneous emphysema, and vomiting. Diagnosis is made through computed tomography scan and esophageal contrast studies. Treatment of BS is geared towards control of mediastinitis and sepsis, and repair of the perforation or reestablishment of the continuity of the gastrointestinal tract. We report the case of a 46-year-old male with BS, who was initially managed with a conservative resection of the perforated esophagus 48 hours after the onset of symptoms. When the mediastinitis persisted we decided to do a subtotal esophagectomy and subsequent esophageal reconstruction.
Esophagectomy

A 38-year-old female was admitted due to recurrent right upper quadrant (RUQ) abdominal pain. Three years prior to admission, the patient complained of a sudden onset of RUQ pain radiating to the right flank area. A month after the onset of pain, she consulted a physician, and she was advised to undergo endoscopy, but she did not comply. Three months after the consultation, an abdominal ultrasound was done, revealing a simple hepatic cyst. She then underwent aspiration of the cyst. However there was no resolution of the pain. A contrast-enhanced abdominal computed tomography (CT) scan revealed a recurrence of the hepatic cyst. Subsequently, she underwent laparoscopic fenestration of the cyst in liver segments VI, VII, and VIII. The biopsy results confirmed that the hepatic cyst was a hydatid cyst caused by Echinococcus granulosus. A month after the procedure, the abdominal pain recurred, and a repeat CT scan revealed another recurrence of the cyst. The patient was advised to undergo open surgery, but she did not consent. The patient denied taking anthelmintic drugs in the past. She did not experience any other symptoms—such as jaundice, nausea, vomiting, anorexia, or weight loss—along with the RUQ pain. She previously worked in Lebanon as a domestic helper for seven years and then moved to Taiwan, where she was employed for three years for the same work. She denied any direct exposure to dogs or sheep. On physical examination, she had a non-tender, firm, palpable mass in the RUQ area of the abdomen measuring 4x4 cm. The rest of the physical examination findings were unremarkable. A contrast-enhanced CT scan of the whole abdomen done two months prior to her admission showed multiple, well-defined, hypodense lesions in the right hepatic lobe. These lesions exhibited mildly enhancing walls and internal septations with rosette or honeycomb appearance. The two largest lesions seen in hepatic segments V and VII measured 8.6 x 6.1 x 5.2 cm and 9.5 x 8.5 x 7.4 cm, respectively (Figure 1). Similar hypodense lesions were seen in the right retroperitoneal space. At least two lesions were visible in the right perirenal space, measuring 8.8 x 6.1 x 6.5 cm and 6.1 x 5.9 x 3.8 cm, and at least two other lesions were visible in the right anterior pararenal space, within the region of the distal ascending colon, measuring 6.0 x 5.5 x 5.4 cm and 7.9 x 6.4 x 5.1 cm (Figure 2). At this point, we diagnosed the patient as having a recurrent hydatid cyst in the right hepatic lobe, with intraperitoneal extension in the right perirenal space and right anterior pararenal space, based on the CT scan findings. After securing medical clearance and administering mebendazole prophylactically at a dosage of 40 mg/kg/day, taken 3 times a day for 7 days prior to surgery, we aimed to sterilize the hydatid cysts and prevent surgical contamination.1 We did an exploratory laparotomy through a reverse L (Makuuchi) skin incision on the right upper abdominal quadrant (Figure 3). We subsequently performed a layered dissection down to the peritoneum. Intraoperatively, we noted adhesions at the posterior segments of the liver, right diaphragm and mid transverse colon. We then meticulously performed adhesiolysis. With extreme caution, we ensured to prevent any spillage of the cystic contents into adjacent structures and the abdominal cavity. Then, we covered the abdomen with abdominal packs soaked in 95% ethanol. Intraoperative liver ultrasonography revealed only one cystic lesion involving hepatic segments V, VI, and VII. The cyst was adherent to the right subdiaphragmatic area. We also noted multiple intraperitoneal cysts: one adherent to the right perirenal area measuring 8 x 6 cm, another adherent to the distal ascending colon and the mid transverse colon measuring 7 x 6 cm, and a third one non-adherent and floating in the anterior pararenal area measuring 4 x 4 cm. Before excising the intrahepatic mother cyst, we aspirated approximately 30-40 ml of cyst fluid and infused the cyst with an equivalent amount of 95% ethanol. After 15 minutes, we reaspirated the infused ethanol. We first carefully excised the intraperitoneal extensions of the cyst, (Figure 4) starting with the cyst in the distal ascending colon, then the cyst in the anterior pararenal area, and finally the right perirenal cyst, taking extreme caution to avoid rupturing the cyst. We then proceeded with the dissection of the hepatoduodenal ligament, where the portal triad is located, to provide access for our Pringle Maneuver. This step was followed by adhesiolysis at the right subdiaphragmatic area. Because of dense adhesions, there was a diaphragmatic injury, for which we performed phrenicorrhaphy. We then mobilized the right hepatic lobe through careful dissection of the triangular and coronary ligaments. The margins were marked under ultrasound guidance and the Pringle Maneuver was applied intermittently. We then carried out a parenchymal-sparing resection of segments V, VI, and VII. After securing hemostasis, we placed a Jackson Pratt drain in the subhepatic area. At the end of the surgery, we successfully resected hepatic segments V, VI, and VII, which contained an intrahepatic mother cyst with multiple spherical daughter cysts. Additionally, we excised three secondary cysts from the intraperitoneal area. Grossly, the excised specimen showed the right posterior segment of the liver with a surgically resected yellowish multiseptated cyst attached to it. This cyst has a fibrous rim and it contains several variable-sized daughter cysts (Figure 5). The excised intraperitoneal cyst from the distal ascending colon to mid transverse colon area (Figure 6), has a thick wall with a laminated external layer (Figure 7). The histopathological examination of the hydatid cyst showed E. granulosus protoscolices containing four acetabula and an armed rostellum with 30 to 36 hooks (Figure 8) . Sections of the liver showed liver parenchyma that was infiltrated by mononuclear cells. Adjacent to the liver parenchyma, the hydatid cyst wall contains an outer acellular laminated membrane, a germinal membrane, and remnants of the E. granulosus protoscolices, which resembled grains of sand (Figure 9 and 10). Postoperatively, the patient complained of dyspnea and tachypnea. On chest physical examination, we noted decreased breath sounds on the right. A chest x-ray done revealed a right-sided pneumothorax. Pneumothorax can occur during hepatectomy due to the escape of intraperitoneal carbon dioxide gas into the pleural cavity.2 We performed a chest tube thoracostomy insertion, and removed the tube after 5 days, once we observed full expansion of the patient’s right lung. We discharged the patient on the 9th postoperative day and prescribed oral antibiotics and pain relievers as home medications. Cystic echinococcosis (CE) or hydatid disease is a zoonotic parasitic disease caused by infection with the larval stage of the tapeworm E. granulosus. Dogs and other carnivores are definitive hosts, while sheep, cattle, and goats are intermediate hosts. Humans are accidental, intermediate hosts and become secondarily infected by ingesting food or water contaminated with eggs or gravid proglottids that are excreted in the definitive host’s feces. CE is endemic in North and East Africa, South America, China and Central Asia, and the Mediterranean countries.3 4 5 6 This disease has a low prevalence in Southeast Asia, particularly the Philippines.7 In our case, the patient probably acquired the infection when she worked in Lebanon, where echinococcosis is endemic. The liver and the lungs are the most common sites of the disease in humans. The concomitant occurrence of the cyst in the retroperitoneum or other intra-abdominal spaces is extremely rare,8 9 and it is associated with a high mortality and disability rate.10 Abdominal CT scan is a good imaging technique for visualizing wall calcifications in CE,11 and in our patient, enhancing walls and internal septations, which represent the walls of daughter cysts, were seen. Peritoneal seeding or cyst dissemination can occur due to a previous hepatic hydatid cyst surgery or after a spontaneous or traumatic rupture.12 These secondary cysts are formed from the liberated protoscolices caused by rupture of the daughter cysts.13 Although rare, when a cyst ruptures into the peritoneal cavity, it can lead to reactions ranging from mild hypersensitivity reaction to potentially fatal anaphylactic shock.14 A preoperative course of oral albendazole or mebendazole, as in the case of our patient’s medication, sterilizes the cysts and reduces their tension, thereby facilitating the surgery.15 16 It also kills most of the protoscolices within the hepatic hydatid cyst.17 Postoperatively, these drugs significantly reduce the risk of cyst recurrence.16 The prognosis of CE is generally good, and a complete cure is possible with total surgical excision without spillage.18 For hepatic echinococcosis, it is crucial to prioritize radical surgical resection in the initial surgery and preoperative anthelmintic therapy to minimize morbidity and recurrence often linked with conservative surgery.16 19
